Abstract: البطين الايمن او البطين المنسي هو عبارة عن حجرة ذات شكل غير منتظم وتركيب هندسي معقد . على الرغم من ان التركيز كان في السابق على الجزء الايسر من القلب من الناحية الوظيفية والمرضية ، فهناك عدد متزايد من الادلة على اهمية البطين الايمن وخاصة اهميته في الحفاظ على استقرار الدورة الدموية للجسم ، مستوى النشاط في المرضى الذين يعانون من قصور القلب المزمن ومدى التحسن في المرضى الذين يعانون من امراض صمامات القلب.ارتفاع ضغط الدم الشرياني هو مشكلة صحية عامة رئيسية واسعة الانتشار على المستوى العالمي. تعرف امراض القلب الناتجة عن ارتفاع ضغط الدم باعتلال عضلة القلب الناتجة عن استجابة عضلة القلب للاجهاد الميكانيكي الناتج عن ارتفاع ضغط الدم وتاثير الهرمونات العصبية وعوامل النمو التي تؤدي الى تشوهات متنوعة تشمل تضخم البطين الايسر , الاضطراب الانقباضي والانبساطي ، ومضاعفاتها السريرية بما في ذلك عدم انتظام ضربات القلب وقصور القلب.في دراسة صدى القلب للبطين الايمن ، يجب اجراء التقييم الشامل باستخدام نوافذ صوتية متعددة وتقنيات مختلفة. ان طريقة تتبع البقع الصغيرة باستخدام تخطيط صدى القلب ثنائي الاتجاه هي طريقة جديدة لحساب تشوه عضلة القلب في الصور القياسية ذات المقياس الرمادي حيث كل قطعة صغيرة من عضلة القلب في صورة تخطيط صدى القلب لديها نمط فريد خاص بها من البقع.كان الهدف من هذه الدراسة هو : تقييم تاثير ارتفاع ضغط الدم الشرياني على وظيفة البطين الايمن الانقباضي والانبساطي مقارنة مع المجموعة الضابطة وتحديد تاثير ارتفاع ضغط الدم الشرياني على ميكانيكة البطين الايمن بقياس قيمة التشوه الطولي ثنائي البعد .وكان العدد الاجمالي المشمول في الدراسة ( 200 ) شخص من كلا الجنسين ( 118 من الرجال و82 من الاناث ) ، تتراوح اعمارهم من ( 40 - 60 ) سنة ، وتم تقسيمهم الى مجموعتين : 1 - 100 شخص من المرضى الذين يعانون من ارتفاع ضغط الدم الشرياني . 2 - 100 شخص من الاشخاص الاصحاء يمثلون المجموعة الضابطة. وقد تم اخذ التاريخ الطبي الكامل ، تخطيط القلب الكهربائي , قياس ضغط الدم , تصوير الصدر بالاشعة السينية وقياسات الطول والوزن لكل الاشخاص , تم اجراء تخطيط صدى القلب لجميع الاشخاص باستخدام جهاز GE Vivid E9® .نتائج هذه الدراسة اكدت وجود فرق معتد من الناحية الاحصائية فيما يتعلق بوظيفة البطين الايمن الانبساطية بين مجموعة المرضى والمجموعة الضابطة ( P = 0.001 ) .وفيما يتعلق في قياس قيمة التشوه في البطين الايمن كذلك اكدت الدراسة انخفاض قيمة التشوه في البطين الايمن للمرضى مقارنة بالمجموعة الضاغطة وكان الفرق معتد من الناحية الاحصائية ( P = 0.001 ) .و كشفت الدراسة ان نسبة الارجحية من الانحدار اللوجستي متعدد المتغيرات ان سمك الحاجز بين البطينين كان المؤثر الاكبر على قيمة التشوه في البطين الايمن .نتائج هذه الدراسة وضحت انخفاض نسبة التشوه الطولي للبطين الايمن وبالتالية تاثر الوظيفة الانقباضية عند مجموعة المرضى وعلاقة هذا التاثر القوية مع تضخم الحاجز بين البطينين الشيء الذي لم تستطع الفحوصات التقليدية في اكتشافه | The right ventricle or the forgotten chamber is multi - compartmental in orientation with a complex structural geometry. Although the focusing in cardiology was placed on left heart physiology and pathology in the past, there is a growing body of evidence for the importance of the RV especially the maintenance of normal body hemodynamics, exercise capacity in chronic heart failure and survival in patients with valvular heart disease. Arterial hypertension is a major public health problem due to its high prevalence globally. Hypertensive heart disease is the cardiomyopathy which result from myocardial response to the mechanical stress from elevated blood pressure , the influences of neurohormones , growth factors, and cytokines and then leads to variety of abnormalities includes left ventricular hypertrophy (LVH), systolic and diastolic dysfunction, and their clinical complication including arrhythmias and heart failure .In echocardiographic studies, a comprehensive assessment of the right ventricle should be performed using multiple acoustic windows and different image techniques .The two dimensions speckle tracking echocardiography is a novel non - invasive echocardiographic method to calculate myocardial deformation in standard grey - scale images in which every little piece of myocardium in echocardiography image has its own unique pattern of speckles. The aim of this study was to : evaluate the effect of systemic arterial hypertension on systolic and diastolic right ventricular function and to determine the effect of systemic arterial hypertension on right ventricle mechanics using two dimensional longitudinal strains.The total number of hypertensive patients and apparently healthy control subjects were (200) of either sex (118 male and 82 female), their age range from (40 - 60) year; they were divided into two groups : 100 Patients with hypertension, 100 apparently healthy control subjects. Each patient and control subject was submitted to full medical history, physical examination, ECG, chest X - Ray, blood pressure determination and subject’s anthropometry measurements. Echocardiography was performed for all subjects using a GE Vivid E9® system in which M - mode, two dimensional , color, pulse and continuous wave Doppler , tissue Doppler and speckle tracking imaging were obtained according to the American Society of Echocardiography guideline of using Echocardiography in Adult Hypertension.Trans - tricuspid E/A ratio was decreased in hypertensive group (1.10±0.12) versus (1.39±0.28) in normotensive group with statistically significant difference p value =0.001. The mean tricuspid E/ é ratio was (4.95±1.34) in hypertensive patients while was (3.90±0.98) in control group, the p value was 0.001 and there was significant difference between them. It was observed that the mean 2D - RVGLS was ( - 20.12 ± 3.80) % in hypertensive patients versus ( - 25.90 ± 2.18) in normal subjects, the P value was 0.001 and there was significant difference between the two groups. The odds ratio of multivariate logistic regression revealed that the diastolic interventricular septum thickness was the strongest factor affect RVGLS in this study, odds ratio for IVSD, RWT, and LVPW were respectively 2.418, 1.978, and 1.761. This study conclude that RV longitudinal strain is significantly impaired in hypertensive patients group and strongly correlates with heart remodeling and it is superior to more conventional functional parameters of RV systolic function.

Abstract: ان الصحة الانجابية هي انعكاس للحالة الصحية العامة والتي تشمل الصحة العقلية والفيزيائية والاجتماعية وليس مجرد مجموعه الامراض المتعلقة بالجهاز التناسلي ووظائفه وعليه يعد العقم مرضا يستحق التشخيص والعلاج . يعرف العقم على انه عدم القدرة على الانجاب بعد سنة من الزواج بدون وجود اي مانع للعلاقة بين الزوجين . يشمل العامل الذكري حوالي 25 - 30 % من كل حالات العقم وايضا 30% اخرى بالاشتراك مع العامل الانثوي . ان 60% من عقم الرجال ناتج عن عوامل جينية اما الاسباب الاخرى فقد تكون نتيجة لدوالي الخصيتين ، عوامل بيئية ، عقاقير طبية ، تعاطي الكحول او التعرض المستمر للحرارة العالية او المواد الكيميائية....الخ. يعد مرض دوالي الخصيتين من الامراض الشائعة بين الرجال الذين يعانون من العقم وهو عبارة عن توسع وتعرج الاورده الناقلة للدم الراجع من الخصيتين نتيجة لتلف الصمامات الوريدية وينعكس ذلك سلبا على الوظيفة الطبيعية للخصية نتيجة لارتفاع درجه حرارة الخصية بسبب تراكم الفضلات الكيميائية من الغدد فوق الكلوية وكذلك الكليتين اضافة الى اسباب اخرى. يشكل دوالي الخصية السريري حوالي 15% بين الرجال ويشخص سريريا بفحص الخصيتين . اما في حالات اخرى لايمكن تشخيص دوالي الخصيه عن طريق الفحص السريري فقط وعليه تستخدم وسائل اخرى للتشخيص حيث يتم استخدام اجهزه الفحص بالموجات فوق الصوتية (السونار) لغرض تشخيص حالات كهذه ويسمى الدوالي غير السريريه وهو موضوع البحث . اجريت الدراسة على 122مريضا في عيادة علاج العقم في مستشفى اليرموك التعليمي بغداد/العراق. وقد استثني من الدراسة اي مريض مصاب باي مرض ممكن ان يتعارض مع الخصوبة وقد اخذت معلومات عامة من المرضى كذلك تم قياس الطول والوزن وقد اجريت لهم بعض التحاليل المختبرية كتحليل السائل المنوي وقياس مستوى بعض الهرمونات في الدم والتي شملت الهرمون المحفز للحويصلات((FSH,هرمون الجسم الاصفر (LH) وهرمون الشحمون الذكري(Testosterone) .كذلك تم فحص السائل المنوي للتاكد من وجود جينFasL)) لمجموعه تتكون من 60 مريضا والذين يعانون من الدوالي غير السريريه في مختبرات جامعة مانشستر مترو بوليتان في المملكة المتحدة. قسم المرضى الى مجموعتين الاولى تشمل المرضى المصابين بالدوالي السرير ي والمجموعة الثانية وتشمل المرضى المصابين بالدوالي غير السريري وقد تم مقارنه النتائج مع 50 مريضا سليما وقادرا على الانجاب . لقد اجريت عمليات جراحيه لعلاج الدوالي غير السريريه ل 60 مريضا وملاحظه التغيرات التي قد تطرا على متغيرات السائل المنوي والهرمونات وكذلك حجم الخصية . اوضحت الدراسة تاثيرا سلبيا بين المرضى الذين يعانون من الدوالي السريريه ومتغيرات السائل المنوي حيث كان التاثير واضحا في قله اعداد الحيوانات المنوية وكذلك سرعتها وشكلها الطبيعي كما اثر سلبا على حجم الخصيه المصابة وكذلك اظهر الفحص زيادة معنويه في هرمون (FSH) ونقص واضح في الهرمون الذكري (T).دون التاثير على هرمون LH)). اظهرت الدراسة تاثير دوالي الخصية غير السريري على متغيرات ا لسائل المنوي حيث كان التاثير على عدد الحيوانات المنوية وكذلك على سرعه الحيوانات المنوية وعلى شكلها الطبيعي دون التاثير على حجم الخصية او على هرمونات FSH),) او LH)).مع تاثير معنوي واضح على هرمون التستوستيرون(T) وكانت نتائج فحص ال FasL))مرتفعه لدى مرضى المجموعه. يستنتج من هذه الدراسة ان دوالي الخصية غير السريريه له تاثير واضح على بعض متغيرات السائل المنوي والهرمون الذكري وان اجراء العملية الجراحية لبعض المرضى يساعد في تحسن مستوى الخصوبة لديهم | Reproductive health is a state of complete physical, mental and social well - being and not merely the absence of disease or infirmity in all matters relating to the reproductive system and to its functions and processes. Infertility should, therefore considered to be a disease process worthy of investigation and treatment. Infertility defined as the inability of a couple to conceive after 1 year of unprotected intercourse. Male factors alone constitute about 25% - 30% of all cases of infertility, and they contribute to another 30% in combination with female factors and about 60% of male factor infertility may be due to genetic causes, others could be due to varicocele, genitourinary infections, environmental agents drugs, alcohol, life style factors like age and obesity. Varicocele is a state of dilated, elongated and tortuous veins of the pampiniform plexus of the spermatic cord typically developed during adolescent and have been found in about 15٪ of the general populations This condition is pathophysiologically characterized by retrograde flow in testicular veins found clinically as the presence of a palpable, soft scrotal mass, could be associated with mild to moderate pain, and they can also be associated with infertility. The size of varicocele is variable according to the severity of the disease. It ranges from large palpable mass of veins easily felt by the patient to varicocele that is only discovered by ultrasound study called subclinical varicoele. The treatment of the large sized varicocele is recommended and known to cause relief of the symptoms and might cause improvement to the seminal fluid quality and the state of fertility while the subclinical varicoele treatment is still controversial as there are results of some studies that showed a significant improvement of fertility after surgical treatment otherwise the treatment in many centers is still not indicated. The study objectives were to determine the relationship between subclinical varicocel and male fertility parameters in addition to follow up treated subclinical patients to determine the effects of surgical treatment on the seminal fluid and fertility. Data analyzed for 122 patients included in this study , full comprehensive history was taken ,physical examination ,testicular color Doppler ultrasound examination , pre and post operative assessments of seminal fluid analysis also evaluation serum levels of some reproductive hormonal profile includes, Follicle stimulating hormone (FSH), Luteinizing hormone (LH) and Testosterone (T) in addition to the expression of FasL mRNA gene in seminal sperms of the patients with subclinical varicocele . The Doppler ultrasound was done to all included patients to measure the testicular volume and the accurate size of the dilated testicular veins to diagnose the subclinical cases , the veins diameter 2.5 mm was used as a cutoff point. Follow up was done for 60 patients of subclinical group pre and post varicocelectomy .Fifty healthy fertile male of similar age were included in this study as a control group.The study was done in male infertility clinic of Al - Yarmouk Teaching Hospital Baghdad, Iraq from the 1st of October 2013 to the end of December 2014 while the FasL expression of 60 samples of subclinical varicocele patients were studied in Manchester Metropolitan University . Health and science laboratories - UK. Results showed that the subclinical varicocele affects male fertility with a significant negative correlation between subclinical group and some of semen parameters including : sperm morphology, percentage of progressive motile sperms and also a significant positive correlation between sperm count and FasL gene. The results also supported the hypothesis of clinical varicocele effects on male fertility as there was a significant negative correlation with the total sperm count, percentage of progressive motile sperms and also there was a significant increase in FSH with decreased testosterone (T) and mild decrease in the testicular volume. From this study we can conclude that subclinical varicocele cause decrease in sperm count, motility and sperm morphology and to some extend hormonal serum levels but no significant changes for testicular volume. Samples of subclinical patients showed a significant expression of FasL RNA and the surgical treatment of such cases gave an improvement to the state of fertility.

Cryopreservation may lead to deleterious changes of sperm structure and function. Cryoinjury is not limited to the freezing process but may also occur during the thawing process as the ice melts or recrystallizes. It have been reported that cryopreservation/thawing significantly lead to alterations of sperm DNA integrity and could alter the quality of the spermatozoon’s nucleus. Cryopreservation induces oxidative stress in the spermatozoa due to increasing rate of lipid peroxidation and suppression of the antioxidant enzyme defense mechanism. These effects of cryopreservation lead to spermatozoa damage including nucleic acids. Subjects and methods : This prospective study carried on 70 cryopreserved semen samples. Each sample wasdivided into two parts, one part is unprepared and other part was prepared by swim - up technique and each part is divided into 3 parts, freezed and thawed by three methods of thawing by laser irradiation till melting for one part, and by room temperature and water bath at 37°C for the other two parts. The semen parameters were assessed by microscopical examination and the DNA integrity assessed by acridine orange test and comet assay before vitrification and after the three methods of thawing as well as before and after preparation. Result : The results of cryopreserved semen samples showed that laser irradiation thawing has a significant increase in sperm motility as well as a significant decreased DNA fragmentation (P < 0.05) versus room temperature and water bath thawing in addition sperm preparation by swim up method also lead to improve sperm motility and DNA integrity (P < 0.05).Conclusions : Vitrification has a deleterious effect on sperm DNA integrity and motility. Laser irradiation thawing methods of post freezing sperm improves post - thaw motility and DNA integrity. Sperm preparation by swim up technique for sperm preparation increasing motility and decrease DNA damage after thawing . The results of the acridine orange test and comet assay gave relatively similar predictive values for DNA fragmentation.

Abstract: العقم هو مرض من امراض الجهاز التناسلي يقصد به عدم قدرة الزوجين على الانجاب او تحقيق الحمل السريري بعد 12 شهرا او اكثر من الجماع الطبيعي الغير المحمي. هرمون مضاد مولريان (AMH) هو البروتين الذي يرتبط هيكليا الى اكثر من 35 الببتيدات مثل انهيبين، اكتيفين، وبروتينات العظام الشكلية وعوامل تمايز النمو، وكثير من هذه الببتيدات تشارك في الوظيفة الانجابية في كلا الجنسين. هرمون مضاد مولريان يمثل علامة بيولوجية للحجم النسبي لاحتياطي المبيض، وعدد الخلايا في الاحتياطي الجريبي الذي يساعد في التقنيات المساعدة على الانجاب ويمكن استخدامها للتنبؤ بتوقيت انقطاع الطمث. قد يكون هرمون مضاد مولريان مفيد كعلامة لضعف المبيض في متلازمة تكيس المبايض، حيث تعكس مستويات هرمون مضاد مولريان عدد الجريبات النامية من المبيض. وهومفيد ايضا في التنبؤ ببعض حالات عجز المبيض في متلازمة تكيس المبايض لكون مستويات هرمون مضاد مولريان تعكس عدد جريبات المبيض النامية. وهو مفيد ايضا في التنبؤ في حالة عدم استجابة المبيض خلال عمليات التخصيب في المختبر او اطفال الانابيب (IVF). مستويات هرمون مضاد مولريان مفيدة في اتخاذ قرار بشان بروتوكولات التحفيز في عمليات اطفال الانابيب (IVF) ويساعد في تحديد عدد الاجنة التي يتم نقلها في عمليات التقنيات المساعدة على الانجاب لزيادة معدلات نجاح الحمل وتقليل خطر متلازمة فرط المبيض. اجريت هذه الدراسة في مستشفى كمال السامرائي لعلاج العقم واطفال الانابيب ومركز بغداد التخصصي لعلاج العقم واطفال الانابيب / بغداد - العراق، تم تقسيم مجموعات الدراسة الى مجموعتين، اللواتي لديهن متلازمة تكيس المبايض والمجموعة الثانية تتالف من الذين ليس لديهم تكيس المبايض (انثى عادية على ما يبدو مع عامل العقم ذكري)، وقد سجلت في هذه الدراسة المرتقبة ، خمسة واربعين مريضة تتراوح اعمارهن بين 18 و42 عاما يخضعن لعملية الحقن المجهري. وقد صممت الدراسة لمعرفة دور مستويات مصل الدم ومستويات السائل الجريبي( (FFمن هرمون مضاد مولريان(AMH)، الهرمون المنبه للجريب ((FSH ،الهرمون المنشط للجسم الاصفر( (LH،هرمون الاسترادايول (E₂) والانسولين في التنبؤ بالنتيجة السريرية (الحمل) بعد عمليات الحقن المجهري في النساء اللواتي يعانين من متلازمة تكيس المبايض واللواتي لديهم اباضة اعتيادية (عامل ذكري). ولاعداد قيم قطعية محددة لهرمون مضاد مولريان في مصل الدم والسائل الجريبي للاستفادة منها في التنبؤ بنتائج الحمل، وكدلك تقييم العلاقة بين النتائج التي تم الحصول عليها للهرمونات المدروسة في مصل الدم والسائل الجريبي. اظهرت نتائج هذه الدراسة وجود زيادة معنوية في مستوى هرمون مضاد مولريان في مصل الدم لدى النساء اللواتي يعانين من تكيس المبايض من النساء اللواتي لا يعانون من تكيس المبايض (P = 0.001)، فيما يتعلق بالهرمونات المقاسة الاخرى، اظهرت النتائج عدم وجود فرق معنوي بين مستويات الهرمونات في مصل الدم بين النساء اللواتي يعانين من تكيس المبايض من النساء اللواتي لا يعانين من تكيس المبايض (P = 0.034)، كما لوحظ وجود زيادة معنوية في مستوى هرمون الاسترادايول في مصل الدم في اليوم الثاني للدورة الشهرية لدى النساء اللواتي يعانين من تكيس المبايض من النساء اللواتي لا يعانين من تكيس المبايض (P = 0.025) فيما يتعلق بالهرمونات المقاسة الاخرى، كشفت النتائج عن عدم وجود فرق معنوي بين مستويات السائل الجريبي لهذه الهرمونات في النساء اللواتي يعانين من تكيس المبايض من النساء اللواتي لا يعانين من تكيس المبايض. عند اجراء المقارنة بين مستوى هرمون مضاد مولريان في مصل الدم وسائل الجريبات ومستويات الهرمونات الاخرى عند النساء اللواتي يعانين من تكيس المبايض والنساء اللواتي لا يعانين من تكيس المبايض من خلال قياس قيم الاختلافات المقترنة، كانت اكبر القيم في مستوى هرمون الاسترادايول ₂E بعده هرمون مضاد مولريان ، ثم هرمون المنبه للجريب (FSH) ، ثم الهرمون المنشط للجسم الاصفر (LH)،ثم الانسولين تعاقبا. عند اجراء دراسة القيم القطعية في مصل الدم والسائل الجريبي لهرمون مضاد مولريان لغرض التنبؤ بنتائج الحمل باستخدام منحنى النسب المئوية 90 و95 عند النساء اللواتي يعانين من تكيس المبايض والنساء اللواتي لا يعانين من تكيس المبايض وجميع المرضى في الدراسة، وهذا قد يساعد في التنبؤ بالنتائج السريرية (الحمل). لوحظ ارتباط مستوى هرمون مضاد مولريان مباشرة مع نتائج الحمل السريري. باستخدام غير الحوامل (الذين لديهم تكيس المبايض والذين لا يعانون من تكيس المبايض) بشكل عام لادخال مستوى قيم قطعية للتنبؤ بنتيجة الحمل. اظهرت مؤشرات حساسية وخصوصية هرمون مضاد مولريان والهرمونات الاخرى في المصل والسائل الجريبي ان مؤشر حساسية وخصوصية هرمون مضاد مولريان في المصل هي (79٪) وفي السائل الجريبي هي (70.3٪) وهما يمثلان اعلى قيمة مقارنة بالهرمونات المقاسة الاخرى، وهي هرمون الاسترادايول ₂E ، هرمون المنبه للجريب (FSH) ، الهرمون المنشط للجسم الاصفر (LH)، الانسولين ومقاومة الانسولين. ومن خلال دراسة منحنى روك للمصل والسائل الجريبي لهرمون مضاد مولريان وغيرها من الهرمونات وهي الاسترادايول ₂E ، هرمون المنبه للجريب (FSH) ، الهرمون المنشط للجسم الاصفر (LH)، الانسولين ومقاومة الانسولين ، تبين ان اكبر مساحة لما تحت المنحنى ((AUC كانت تعود لهرمون مضاد مولريان في المصل وبعدها لهرمون مضاد مولريان في السائل الجريبي. من هذه الدراسة نستنتج الاهمية السريرية لقياس هرمون مضاد مولريان في المصل وفي السائل الجريبي في تقييم النتائج السريرية (الحمل) بعد عمليات الحقن المجهري في النساء اللواتي تعانين من متلازمة تكيس المبايض ، ايضا ان قياس مستويات هرمون مضاد مولريان في المصل وفي السائل الجريبي مهمة في التنبؤ بحالات متلازمة تكيس المبايض في النساء التي تقوم بعملية الحقن المجهري، حيث ان زيادة مستويات هرمون مضاد مولريان تعكس شدة المرض. ان القيم القطعية التي تم الحصول عليها من تركيزات هرمون مضاد مولريان في المصل وفي السائل الجريبي مهمة جدا للتنبؤ بنتائج تقنية الحقن المجهري (ICSI) واستكمالها او انهاءها في (النساء اللواتي يعانين من متلازمة تكيس المبايض والنساء اللواتي لا يعانين منها ). | Infertility is a disease of the reproductive system refers to an inability of a couple to achieve a clinical pregnancy after 2 years or more of regular unprotected sexual intercourse. Anti - Müllerian hormone (AMH) is a protein that is structurally related to more than 35 peptides like inhibin , activin, bone morphogenetic proteins (BMPs) and growth differentiation factors, many of these involved in reproductive function in both sexes. AMH serves as a biomarker for the relative size of the ovarian reserve; the number of cells in the follicular reserve that helps in assisted reproduction and can be used to predict the timing of menopause. AMH may be useful as a marker of ovarian impairment in polycystic ovary syndrome, since AMH levels reflect number of the developing ovarian follicles. It is also useful in prediction of poor ovarian response during in vitro fertilization (IVF). AMH levels are useful in deciding what stimulation protocols for IVF cycles and helps in decisions about the number of embryos to transfer in assisted reproduction techniques to increase the pregnancy success rates and decreasing the risk of ovarian hyperstimulation syndrome. The study was designed to investigate the role of serum and follicular fluid levels of AMH, Follicular stimulating hormone (FSH), Luteinizing hormone (LH), Estradiol (E2) and insulin in prediction of clinical outcome (pregnancy) in women with PCOS undergoing intracytoplasmic sperm injection(ICSI) and those with normal ovulation and to set up the cutoff values of serum and follicular fluid AMH concentration for prediction of pregnancy outcome, and to evaluate the relationship between the obtained results of the studied women’s in blood serum and in follicular fluid (FF). This study was conducted in Kamal Al - Samarrai hospital for infertility treatment and IVF and in Baghdad Specialist Center for treatment of infertility and IVF/Baghdad - Iraq, the study groups were divided into two groups, those with polycystic ovarian syndrome (PCOs) and those without PCOs (normal female with male factor infertility), forty five female patients aged between 18 - 42 years undergoing IVF/ICSI treatment were enrolled in this prospective study. The results of this study showed a significant increase in serum AMH level of PCOs women’s than that of non PCOs women’s (0.001), in regard to other measured hormones, the results revealed that there was no significant difference between serum levels of these hormones in PCOs and non PCOs women’s. There was significant increase in follicular fluid (FF) AMH level of PCOs women’s than that of non PCOs women’s (P= 0.034).There was also a significant increase in FFE₂ level in non PCOs women’s than in PCOs women’s (P=0.025), in regard to other measured hormones, the results revealed that there was no significant difference between FF levels of these hormones in PCOs and non PCOs women’s. In comparison between the serum and follicular fluid ( FF) AMH level and other parameters in PCOs women’s and in non PCOs women’s by measuring the paired differences values, the greatest values was in the E₂ level after that the AMH, then the FSH, LH, Insulin consequently. By studying the cutoff values of the serum and follicular fluid AMH concentration for prediction of pregnancy outcome by using the percentiles 90 and 95 in PCOs, non PCOs and all patients in the study, this may help in prediction of clinical outcome (pregnancy). AMH was directly correlated with clinical pregnancy outcome. Using non pregnant (PCOs and non PCOs) in general to introduce a cutoff level for prediction of pregnancy outcome. The sensitivity and specificity index of serum and follicular AMH and other hormones, revealed that the sensitivity and specificity index of serum AMH (79%) and of follicular AMH (70.3%) have the highest value in comparison with other routine measured hormones, E₂, FSH, LH, Insulin and Insulin resistance. The Receiver operating characteristic (ROC) curve for serum and follicular fluid AMH and other parameters, E₂, FSH, LH, Insulin and Insulin resistance, the greater area was founded belong to serum AMH then the FF AMH. From this study concluded the clinical importance of the measurements of serum and FF levels of AMH in assessment of successful ICSI techniques in PCOS infertile women, also the measurements of serum and FF levels of AMH are important in prediction of cases of PCOS in women’s undergoing ICSI techniques. The obtained cut - off values of serum and FF AMH concentrations are very important for prediction of the outcome of the ICSI technique and its continuation or termination in (PCOs and non PCOs).

It results from dopaminergic neuronal degeneration mainly in substantia nigra that may extend to other parts of the brain. The main cause of this disorder still unknown, although many factors that contributes in its pathogenesis. Of these factors, there are inflammation, oxidative stress, and mitochondrial dysfunction in addition to genetic predisposition.Symptoms related to Parkinson’s disease are motor, non - motor. The present study relates the autonomic dysfunction of Parkinson disease with the acetylcholine, antioxidants, and tumor necrosis factor in three study groups which are Parkinson patients with autonomic dysfunction, Parkinson patients without autonomic dysfunction and the control groups. The autonomic assessment is done by studying the autonomic tests including cardiovascular autonomic study (Valsalva ratio, 30 : 15 ratio, blood pressure change with posture), and sympathetic skin response, in addition to biochemical testing of acetylcholine, antioxidant, and Tumor necrosis factor levels. Regarding autonomic testing, the results difference that is statistically significant regarding changes of blood pressure in response to posture, in addition Parkinson disease. Acetylcholine level decrease as the disease progress from Parkinson patients without autonomic dysfunction to Parkinson patients with autonomic dysfunction. While antioxidant level was not significant difference between Parkinson patients with and without dysautonomia. On the other hand, tumor necrosis factor increases as the disease worsen to involve autonomic dysfunction. This study shows the effect of tumor necrosis factor and oxidative stress affecting the pathogenesis of Parkinson disease as a whole and autonomic dysfunction in specific

Abstract: Cervical radiculopathy can be defined as pain in a radicular pattern in one or both upper extremities related to compression and/or irritation of one or more cervical nerve roots. In the electrodiagnostic laboratory, various types of electrodiagnostic studies may be considered when evaluating a patient for cervical radiculopathy. Potential tests including (needle electromyography, motor and sensory nerve conduction studies, late responses, and somatosensory evoked potentials) serves to confirm the presence of radiculopathy, establish the involved nerve root level, determine if axon loss or conduction block is present, grade the severity of the process, estimate the age of the radiculopathy and exclude other peripheral nerve diseases that mimic radiculopathy.The aim of this study was to approve the usefulness of the electrodiagnostic studies (NCS, EMG and SSEP) in the diagnosis of cervical radiculopathy, asses the role and accuracy of the SSEP test (specifically spinal N13 component) in the diagnosis of cervical radiculopathy, identify the extent and distribution of cervical paraspinal muscles denervation in cervical radiculopathy and match the electrodiagnostic results with imaging data in the localization of the root lesion involved.This is case control study had been conducted during the period from April 2016 to October 2017. Ninety five (95) patients with cervical radiculopathy with a mean age of (48.4±11) years and twenty six (26) healthy control subjects with a mean age of (45.2±10.1) years involved in the study. Each subject submitted for medical history, clinical examination and electrophysiological study using Nicolete Viking Quest , EMG, NCS, EP measuring system.XIIFor SNCS, Onset latency, SNAP amplitude and conduction velocity, while for MNCS, distal motor latency, CMAP amplitude and conduction velocity, in addition to the minimal F wave latency (that assess the late response) of median and ulnar nerves are performed.Whereas for right and left sides median nerve SSEP test, the following peak and interpeak latencies (1) N9; (2) N13; (3) N20; (4) N9 - N20; (5) N9 - N13 ; (6) N13 - N20 are measured.Concerning the needle EMG, the following parameters; insertional activity, spontaneous activity and motor units action potential characteristics (duration and phases) of the right and left trapezius, rhomboids major, deltoid, biceps, triceps, extensor indicis and first dorsal interosseous muscles are considered and recorded. In addition to the assessment of the spontaneous activity of the cervical paraspinal muscles.The results of this study revealed that there are significant differences; higher values for the patients when compared with that of control groups regarding Rt and Lt sides N13 peak latency, N9 - N13 and N13 - N20 inter - peak latency. Moreover, the sensitivity of SSEP components in comparison with the MRI (as a gold standard) is the higher for that of spinal N13.From the EMG and MRI findings, C6 and C7 cervical roots are the most roots affected in respect to C5, C8 or C4 roots.Consequently, there are mismatching in the percentages of cervical radiculopathies when diagnosed by the MRI of the cervical spine, needle EMG of the upper limbs muscles and that of the cervical paraspinal muscles, in such a way that Rt C7 radiculopathy 71.6% by cervical spine MRI mismatched with that of upper limbs EMG (66.3%) and 5.3% by the cervical paraspinal muscles.However, the percentages of each level of cervical radiculopathy proved to be higher by the combination of the EMG abnormaities of the cervical paraspinalXIIImuscles with that of the upper limbs muscles than by using the EMG of the paraspinal muscles or upper limbs muscles in an isolation (for Rt C6 radiculopathy 4.2% by paraspinal muscles EMG, 66.3% by upper limb and 68.4% by combination.Furthermore, the sensitivity of the EMG in cervical radiculopathy (using the MRI as a gold standard) increases by the combination of the abnormalities of the cervical paraspinal muscles with that of the upper limbs muscles, for example the sensitivity of Lt C6 radiculopathies 89.9% by upper limbs EMG, 93.2% by the combination of the EMG of PSM with that of the upper limbs muscles.In conclusion, traditional electrodiagnostic tests (NCS, EMG and SSEP) proved to be useful and complementary to the clinical examination in the evaluation of patients with cervical radiculopathy. The benefit of SSEP test for the evaluation of radiculopathies is based on the fact that signs and symptoms in radiculopathies can usually be related to injury of the afferent fibers and the SSEP test can monitor injury to these fibers.In addition to, spinal N13 is a sensitive technique suitable for detecting early and mild symptomatic cervical nerve root lesion.Moreover, cervical paraspinal muscles EMG is complementary to the upper limbs muscles EMG since that significant percentages of cervical radiculopathy will be missed if the examination of PSM is not part of the electrodiagnostic evaluation of patients with suspected radiculopathy. Furthermore, the sensitivity of the needle EMG is increased by the combination of the EMG of the paraspinal muscles with that of the upper limbs muscles, without paraspinal muscles needle EMG the screen of cervical radiculopathy misses much of its sensitivity. Finally, EMG and MRI are valuable and complementary diagnostic tools in the localization and extent of the cervical roots lesion.

Furthermore, it is intricate by a rising incapability to preserve common stages of protein metabolism products (such as urea, creatinine, standard blood pressure, hematocrit, sodium, water, calcium phosphate homeostasis, potassium and acid base balance). A further frequent involvement is the Peripheral neuropathy of Chronic kidney disease. Nevertheless, patients who suffer CKD are further exposed to increase peripheral polyneuropathy. Neurological impediments that is subsidiary to the uremic status, participate fundamentally to the sickness and death to patients who suffer renal failure. The occurrence of peripheral neuropathy stays extreme in advanced renal dysfunction Electrophysiological study (nerve conduction study NCS and electromyography EMG) is useful adjunct test to the medical history and clinical examination in the diagnosis of such complication, early detection and differentiation from an axonal type of peripheral neuropathy. The aims of this study are designed to : (1) Evaluate the function of electrophysiological study (NCS and EMG) in diagnosing the neuropathy for patients who suffer CKD. (2) Decide and rule out the most necessary parameters of NCS and EMG, to be performed as preliminary test in the diagnosis of small fiber neuropathy. (3) Correlation between the severity of the peripheral neuropathy and the level of serum creatinine.Three groups of subjects included in this study : Adult patients of chronic kidney disease not on dialysis yet, Patients on hemodialysis and control subjects. The present study was carried out at the neurophysiology unit in Al - Yarmouk Teaching Hospital, in the a period from June/2016 to September /2017.The control group consists of forty two (42) healthy volunteers (22 males and 20 females). The age of this group ranged between 20 to 75 years with a mean 52.48 ±10.63 years. Males are 22 - 75 years with a mean of age 53.54± 14.57 years, and 20 - 74 years for females with a mean of age 51.42±11.91 years. Eighty patients included in this study had chronic kidney disease. They consist of two groups : A - Forty (40) patients with chronic kidney disease on customary attend the Kidney and Dialysis clinic not on dialysis with steadily high serum creatinine (> 2.5 mg/dl of) either sex (22 males and 18 females), their ages ranging between 35 and 72 years with a mean 55.35 ± 9.05 years. The duration of CKD is ranged between 2 – 10 years, with mean 8.72 ± 3.65 yearsB - Forty (40) patients with chronic kidney disease on regular hemodialysis (21 males and 19 females), their ages ranging between 43 to 70 years with a mean 56.98 ±7.40 years. The duration of CKD is ranged between 7 - 20 years with mean 13.87 ± 5.41 years. All of 122 subjects (patients and control) that were included in this study were informed about the aim and technique of the study and their acceptance was taken.Each subject was submitted to medical history and electrophysiological tests (NCS and EMG) of the two limbs i.e. the upper and the lower. These tests include : 1 - Sensory nerve conducting study (SNCS) for Median, Ulnerand Sural nerves, in which, distal sensory latency, sensory nerve action potential (SNAP) amplitude and sensory nerve conduction velocity (SNCV) are performed. 2 - Motor nerve conducting study (MNCS) for Median, Ulnar, Fibular (Common peroneal), and tibial nerves , which includes measurement of distal motor latency (DML), compound muscle action potential (CMAP) amplitude, Motor nerve conduction velocity (MNCV), Mean F - wave latency, Terminal latency index (TLI), Temporal dispersion (TD%) and Conduction block (CB%).3 - Sympathetic skin response (SSR) of right median and right fibular nerves. 4 - Needle EMG for proximal and distal muscles like : biceps, and 1st dorsal interosseous muscles for upper limb and vastusmedialus, tibialis anterior and Extensor digitorium brevis for lower limb, in which insertional activity, spontaneous activity, motor unit action potential (duration, amplitude and polyphasia%) and recruitment pattern are considered. The results of this study revealed that sensory NCS was considerably altered in all kinds of CKD patients as weigh against the healthy control subjects in the form of prolonged distal sensory latency, decreased SNAP amplitude and slowing of SNCV. However, there were not statistically significant differences (P>0.05) between pre dialysis and post dialysis Peripheral Neuropathy except in the SNAP amplitude of right and left median and right ulnar and sural sensory nerves whereas the differences are statistically significant (p<0.05).As for the study of motor nerve conduction, theprolonged DML, slowing of conduction velocity and prolonged mean F - wave latency are perceived in both groups of patients when compared with those of healthy control subjects. However, the differences are also statistically significant (P<0.01) in the TLI of right median and ulnar nerves, distal CMAP amplitude of the right ulnar nerve, distal motor latency (DML) of left median and right ulnar nerves, MNCV (m/sec.) of left median nerve and prolongation or mean F - wave latency of left median, common peroneal and right tibial nerves (P<0.05). Also Sympathetic Skin Response significantly (P<0.01) changed detected in both groups of patients when compared with those of healthy control.Moreover, in both patients groups, abnormal TD% are observed increased temporal dispersion in CKD pre dialysis patients is found in 39 out of 204 nerves (19.3%) However the higher percentage of abnormal TD% is in the right common peroneal nerve (28.57%), while the lower percentage is in the right ulnar nerve (12.5%).Increased temporal dispersion in CKD post dialysis patients is found in 36 out of 203 nerves (17.73%) However the higher percentage of abnormal TD% is in the right common peroneal nerve (24.13%), while the lower percentage is in the right median nerve (12.5%).In both patients groups, abnormal CB% are observed that the higher percentage of conduction block (CB%) in motor nerves of CKD pre dialysis patient involves right median nerve (25%), while the lower percentage involves right tibial nerve (11.11%).Whereas there are 38 out of 204 examined nerve with conduction block (18.62%).And also show that the higher percentage of conduction block (CB%) in motor nerves of CKD post dialysis patient involves left median nerve (25%), while the lower percentage involves right tibial nerve (7.69%). Whereas there are 34 out of 203 examined nerve with conduction block (16.74%).In conclusion, this study reveals Sensory NCS is more useful and helpful than the motor NCS in the diagnosis of early peripheral neuropathy in CKD pre dialysis also Sympathetic skin response (SSR) abnormality are very useful in the detection of small fiber neuropathy in CKD patients (pre and post dialysis).Moreover, the serum creatinine level have strong correlation with NCS parameters in CKD pre dialysis patients (when increase level of s.cr lead to decrease the NCS parameters).Most CKD patients had abnormal NCS parameters in both limbs, but the abnormalities in the lower limbs are more than the upper limbs

Abstract: يعتبر العقم من المشاكل المتعلقة بصحة الانسان ويؤثرعلى سدس الازواج في عمر الانجاب تقريبا. يعد الذكر مسؤلا عن خمسين بالمئه من مجموع الحالات.الوظيفه الرئيسيه لتقنيات الانجاب المعان هي علاج العقم بما فيها حالات العقم الذكري وزيادة فرص الحمل من خلال التغلب عل | Infertility is a health concern affecting nearly 17% of young couples in their reproductive age. Male factor infertility accounts for 50% of all cases. The key responsibility of assisted reproductive technologies (ART) is the management of male infertility by bypassing seminal fluid disorders. Defective Sperm parameters were responsible for deciding the fertility potential and related to pregnancy rate in vivo as well as in vitro.Today, the classic seminal fluid analysis is found to be of limited importance in describing a couple’s fertility status. There is now clinical evidence to show that damage to human sperm DNA may adversely affect reproductive outcomes and the spermatozoa of infertile men possess substantially more DNA damage than do spermatozoa of fertile men and there appears to be a threshold of sperm DNA damage beyond which embryo development and pregnancy are impaired.In view of that, the aims of the present study were : Evaluation of the influence of defective sperm parameters including concentration, morphology and motility on intracytoplasmic sperm injection (ICSI) outcome represented by fertilization rate, cleavage rate, embryo quality and pregnancy rate. Assessment of the sperm chromatin maturity in infertile men using acidic aniline blue stain and compare it with that of men with normal spermiogram. Discovering the relationship between sperm chromatin status and the semen parameters in infertile males. Finding the relationship between sperm chromatin status and ICSI outcome.This study included 60 infertile couples complaining from either primary or secondary infertility attended the clinics of infertility treatment center and underwent intracytoplasmic sperm injection.They were classified according to their spermiogram to normozoospermic group (N), whose female partner had bilateral tubal block, oligoasthenoteratozoospermic group (OAT) and finally, asthenoteratozoospermic group (AT). The female partners of the last two groups had normal reproductive function according to gynecological examination and laboratory investigations. All female partners included in this study were less than 35 years old to minimize the influence of advanced maternal age on ICSI outcome. Seminal fluid analysis were done for all and aniline blue stain was used in this study to evaluate sperm chromatin integrity. The main results of this study showed that infertile couples with impaired sperm parameters show high percentage of positive aniline blue stain i.e., sperm chromatin maturity defect and it is significantly higher than that in couples with normal spermiogram. The best cut off point of positive chromatin percentage associated with pregnancy was 40% i.e., when sperm chromatin abnormality exceeds 40% as detected by aniline blue staining method; the pregnancy rate start to regress. No significant differences in fertilization rate, cleavage rate, embryo quality and pregnancy rate were found among studied groups.No significant difference in ICSI outcome including pregnancy rate between couples with high percentage of sperm chromatin damage ?30% and those with low percentage of sperm chromatin damage < 30% were found. So the main conclusions are : Defective sperm parameters and chromatin immaturity are significantly associated with each other.Forty percent is the threshold of sperm chromatin immaturity after which ICSI outcome deteriorate and depending 30% as a threshold in this study revealed no significant difference in ICSI outcome among studied groups. Intracytoplasmic sperm injection has corrective and therapeutic role for defective sperm parameters and shows a unique capability to treat the most difficult cases of male infertility.

Abstract: الخلفية : يعتبر اعتلال الاعصاب المحيطية السكري من اكثر مضاعفات داء السكري شيوعا التي تؤثر على الاوعية الدموية الدقيقة. سريريا يؤثر المرض اولا على الاطراف القصيه مؤديا الى فقدان الاحساس في تلك الاطراف على نمط الجورب والقفاز. يؤثر المرض على كل من الالياف ال | Background : diabetic peripheral neuropathy (DPN) is the most common microvascular complication of diabetes mellitus (DM). Clinically, it affects the most distal extremities first resulting in a stock and glove pattern of sensory loss. It affects both small fibers (myelinated and un - myelinated) as well as the large myelinated nerve fibers. However, the earliest manifestations might be due to small fiber dysfunction. Hyperglycaemia and subsequent metabolic derangement is the main pathogenitic factor of DPN. However, oxidative stress, deficiency of neuroprotective factors and neurovascular insufficiency might play a role.AIMS : This study aims to : 1. Test the value of applying SFEMG in the diagnosis of diabetic peripheral neuropathy. 2. Determine the usefulness of SFEMG, compared to the standard NCS, in the early diagnosis of diabetic peripheral neuropathy. 3. Evaluate the correlation of the antioxidant/oxidant status in patients with and without diabetic peripheral neuropathy.Materials and methods : The study was conducted in the period from Nov. 2012 till Apr. 2014 and included 188 patients with type 2 DM that fall within age group of 45 - 65 years. Diabetics that suffer from clinical features of peripheral nerve dysfunction documented with abnormal electrophysiological findings were considered as patients with DPN (138 patients) and those who had no complaint of peripheral nerve dysfunction with normal electrophysiological study were considered as patients without DPN (50 patients). The study also included normal healthy persons who their age and gender matched that patients and considered as control subjects (50 persons). The patients and control enrolled in the study had undergone comprehensive assessment that included : clinical assessment (history and full examination), biochemical assessment (measurement of fasting blood sugar, glycated haemoglobin, total antioxidant capacity and advanced glycation end products) and electrophysiological assessment that included sensory and motor nerve conduction studies (NCS) with single fiber electromyography (SFEMG).Results : The study found that patients with DPN in comparison to patients without DPN and control subjects are older (p?0.05), had longer duration of DM (p?0.01), poorer glycemic control reflected by fasting blood sugar (p?0.01) and glycated haemoglobin (p?0.01), lower level of total antioxidant capacity (p?0.01) and higher advanced glycation end products level (p?0.01). Also, the study showed that the level of total antioxidant capacity and advanced glycation end products on one hand were correlated with the duration of the diabetes (p?0.01) and not correlated with glycated haemoglobin level on the other hand.The electrophysiological findings showed that patients with DPN had significant differences in NCS parameters when compared to patients without DPN and to control subjects in the form of axonal degeneration and demyelination with abnormal single fiber jitter and fiber density which were correlated with the duration of diabetes (p?0.01) but not correlated with glycemic control. Also the study demonstrated that SFEMG findings were correlated with NCS parameters (namely sural nerve) in patients with DPN. This study had concluded that the duration of diabetes, age, glycemic control and oxidative stress are important risk factors of DPN. Routine NCS is important mean for diagnosing DPN but it has limited sensitivity in the diagnosis of early stages of the disease and in assessing nerve degeneration and regeneration. Sensory nerves of lower limbs are helpful in discovering early stages of DPN when other tested nerves are normal. SFEMG examination in diabetic patients is important in showing the degree of re - innervation and nerve regeneration and in identification of subclinical nerve dysfunction.

Abstract: يعتبر داء السكري المصاحب للحمل هو احد مضاعفات الحمل الاكثر شيوعا والتي ترتبط بمعدلات هامة من الاعتلال والوفاة ما حول الولادة , ان العلاج الفعال لداء السكري ما قبل الحمل ولداء السكر المصاحب للحمل قد تبين تحسين النتائج والحد من وفيات ما حول الولادة بالمقارن | Diabetes mellitus complicating pregnancy is one of the most common antenatal complications that are associated with significant perinatal mortality and morbidity(Magee et al., 1993, Schmidt et al., 2001and Platt et al., 2002). Effective treatment of pre - existing as well as gestational diabetes mellitus was shown to improve outcome and reduce perinatal mortality, as compared to untreated patients (Lao TT, et al., 2001and Langer , et al., 2005). Doppler studies have conventionally been utilized for fetal surveillance. The use maternal uterine artery Doppler as a screening tool to predict subsequent development of pre - eclampsia and fetal growth restriction in later gestation have gained acceptance in recent years. Umbilical artery Doppler, middle cerebral artery Doppler have been widely used for the assessment of growth restricted fetuses. The role of Doppler study in diabetic pregnancies has not been unequivocally evaluated. An atherogenic factor, that promotes vascular endothelial growth, insulin - like growth factor - 1 has been implicated with micro vascular complication during pregnancy (Kathryn 2000). Presently, short - term beneficial metabolic effects of recombinant human insulin - like growth nfactor - 1 (rhIGF) - 1 therapy have been demonstrated in numerous diabetic conditions, including type 1 diabetes mellitus, type 2 diabetes mellitus. Until recently, insulin - like growth factor - 1, based upon its endothelial growth promotion, was considered a mediator of vascular disease( Bayes - genis et al., 2001a; 2001b). Conversely, increasing evidence indicate the protective mechanism of insulin - like growth factor - 1 against vascular derangements, relating to its ability of nitric oxide production (Okura et al., 2001). We sought to investigate the impact of insulin - like growth factor - 1 levels on maternal/fetal blood flow in diabetic non - hypertensive pregnant women; an avenue of research that has yet to be fully explored. Taken together, this information will materialize the intervention needed to prevent or at least ameliorate diabetes maternal and fetal outcomes. OBJECTIVES1 - To evaluate effect of diabetes mellitus on utero - and cerebro - placental Doppler velocimetry in pregnant women, such as resistive index (RI), pulsatility index (PI), Systolic/diastolic ratio (S/D)2 - To find whether a meaningful correlation exists between the above mentioned parameters and the levels of HBA1c and maternal IGF - 1.3 - To predict the most sensitive parameter detecting complications of diabetes mellitus on fetal outcomes. MATERIAL AND METHOD In this prospective cohort study a total of 190 pregnant women with single viable fetus, cephalic presentation, were enrolled after having their verbal and written consent and approval of the ethical committee at Faculty of Medicine. They were divided into two Groups : group (Ia) women with gestational diabetes mellitus (n=70), group ( Ib ) women with pre - gestational diabetes mellitus (n=64) and the remaining (n=56) participants (group II) were free from diabetes and hypertension and served as a control group. The study performed at Al Ameer Diagnostic Center in Al Najaf, between March, 2013 and August, 2014.Examination of the participants done twice, in the second and third trimesters. In each time, history and clinical examinations performed with Doppler ultrasonography of the pregnant women including interrogations of bilateral maternal uterine arteries, fetal umbilical and middle cerebral arteries in addition to measurement of IGF - 1 and HbA1c concentrations. RESULTS AND CONCLUSIONS 1 - IGF - 1 mean± SD in second trimester was 582.61± 183.7 ng/ml in group Ia, 429.5± 231.3 ng/ml in group 1b and 278.6 ± 60.8 ng/ml in the group II with significant difference among the groups (P=0.0001) In the third trimester the mean± SD was 653.69 ±197.6 ng/ml in group Ia, 487.5± 242.4 ng/ml in group Ib and 316.6 ± 60.9 ng/ml in group II with significant difference among the groups (P=0.0001).2 - HbA1c mean± SD in second trimester was 6.59± 0.89 % in group Ia, 6.42 ± 0.9% in group Ib and 5.35 ± 0.56 % in group II with significant difference between group Ia and group II, as well as between Ib and group II, but no significant difference between Ia and Ib groups.Third trimester HbA1c mean value was 6.29 ± 0.78 % in group Ia , in group Ib 6.27 ± 0.87 % and 5.08 ± 0.57% in group II.There was no significant difference between group Ia and Ib (P=0.843) , while there was a significant difference between group Ia and group II as well as between group Ib and group II(P=0.0001).3 - Uterine artery Doppler velocimetry was considered more sensitive predictor than other arteries in evaluation of fetal outcomes and its sensitivity in the total studied population (190) was 44.3%, in gestational diabetic pregnancy group was 58.3%, in pregestational diabetic pregnancy 34.3% and in control was 29.4%.4 - Multiple maternal and fetal arterial Doppler studies at same time yield high predictive values in evaluation of fetal outcomes with general sensitivity in the total studied population was 63.6%, specificity 79.4%79, PPV 72.2% and NPV 71.7%. In gestational diabetic pregnancy the sensitivity was 94.4%, specificity was 61.8%, PPV was 72.3%, NPV was 91.3%. In pregestational diabetic pregnancy sensitivity was 88.6%, specificity was 86.2 %, PPV was 88.6 %, NPV was 86.2%. In control healthy pregnancies the sensitivity was 70.6 %, specificity was 71.8%, PPV was 52.2%, NPV was 84.8 %.

Abstract: انخفاض الخصوبة مشكلة شائعة ولكن علاجها في بعض الاحيان غير كافي لعدم تشخيص الاسباب بالكامل. الحديد عنصر ناقل للاوكسجين ولذلك فهو محفز لحيوية كل الخلايا والانسجة في الجسم. نقص الحديد من اكثر مشاكل نقص الغذاء الشائعة في العالم. لذلك ربط الحديد مع الخصوبة يح | Subfertility is a common problem, but the treatment is sometimes inadequate because the causes are not fully diagnosed. Iron is essential for oxygen transport and therefore promotes health of all cells and tissues. Iron deficiency is the most common nutritional deficiency in the world. Therefore, the connection between iron and fertility need more explanation. Some researchers have suggested that iron may be important for ovulation as the egg has an increased demand for iron while it matures and women who do not get sufficient amounts of iron may suffer anovulation and possibly poor egg health, which can inhibit pregnancy at a rate 60% higher than those with sufficient iron stores in their blood. However women planning to become pregnant should test for serum ferritin level and accordingly if low they can use iron supplements because they may help them to prevent iron deficiency and also improve fertility. Vitamin C is essential for the uptake and absorption of iron. The objective of this study was to assess the iron status, vitamin C and some hormone levels in subfertile women. The sample of study consists of 106 women subdivided into two groups : first consist of 76 subfertile women were taken from the outpatient to fertility center in the gynecological and obstetrical teaching hospital in Kerbala city and from multiple gynecology/obstetrics privet clinics. Second consist of 30 fertile women (control and comparative) who obtained from outpatients and some relatives. The subfertile women subdivided into two subgroups according to the cause of subfertility in presented study : first group : ovarian dysfunction (OD) either due to polycystic ovary syndrom (PCOS) or due to other cause (OC) like anovulation, hyperprolactenemia, premature ovarian failure. Second group : unexplained (idiopathic). Also the subfertile women subdivided into two subgroups according to the type of subfertility : primary and secondary. All of them were at reproductive age (16 - 45) years and there BMI ranged between (20 - 45 kg/m2). The study was achieved throughout a period which extends from July 2012 - October 2013. The protocol of study summarized as following : At day 3±1of menstrual cycle (menstrual phase), all women underwent the measurement of concentrations for multiple hormones in the blood like luteinizing hormone, follicle stimulating hormone, estradiole, prolactine and Testosterone. In addition to iron status (serum iron, serum ferrtin and total iron binding capacity) and vitamin C also assessed. And at day 13 of menstrual cycle (near time of ovulation), all women underwent two investigations : first : the measurement of concentrations of luteinizing hormone, serum Leptin and antioxidants as vitamin C and glutathione. In addition to Iron status (serum iron, serum ferrtin and total iron binding capacity) and hemoglobin concentration also estimated. Second : estimation the size and the number of dominant follicles in both ovaries by ultrasonograghy. While at day 23±1 of menstrual cycle (secretary phase), all women underwent two investigations : first : estimation the concentration of serum progesterone to detect ovulation. Second : estimation the endometrial thickness by ultrasonograghy. The results of study shows : • A significant increase (P<0.05) in number of subfertile women with age group (16 - 25) years and there were highly significant decreases (P<0.001) in number of women with age 36 - 45 years for both primary and secondary subfertility. While no significant difference (p>0.05) in age group (26 - 35) years.• A significant increases (P<0.05) in body mass index for subfertile women due to polycystic ovary syndrome. Also a significant increase (P<0.05) in serum leptin for women with overweight and obese as compared with normal weight.• A significant increase (P<0.05) in serum ferritin level for polycystic ovary syndrome at day 13 of menstrual cycle. Also, a significant decreases (P<0.05) in number of polycystic ovary syndrome in those having serum ferritin lower than normal at day 13 of menstrual cycle.• A significant increase (P<0.05) in the number of subfertile women due to ovarian dysfunction other than polycystic ovary syndrome who having a lower serum level of vitamin C at day 3 of menstrual cycle. • A significant increase (P<0.05) in serum testosterone level in polycystic ovary syndrome group at day 3 of menstrual cycle. • A significant increase (P<0.05) in serum prolactine level in group of ovarian dysfunction due to other cause at day 3 of menstrual cycle. when serum ferritin level lower than or within normal value. • A significant decrease (P<0.05) in serum level of luteinizing hormone for group of ovarian dysfunction due to other cause at day 13 of menstrual cycle when serum ferritin less than normal but no significant differences (P>0.05) in serum luteinizing hormone when serum ferritin within normal value. • A significant decrease (P<0.05) in serum luteinizing hormone for group of ovarian dysfunction due to O.C when vitamin C within normal value at day 13 of menstrual cycle.• A highly significant decrease (p<0.001) in endometrial thickness for all subfertile group at day 23 of menstrual cycle.• No significant difference (P>0.05) in serum levels of follicle stimulating hormone, estradiole and glutathione as compared with other parameters in fertile and subfertile women.It was concluded that the decrease in serum ferritin and vitamin C levels in the blood may be associated directly or indirectly with subfertility caused by ovarian dysfunction.

Abstract: يسجل الرسم الكهربائي للدماغ الفعالية الكهربائية الذاتية المتولدة في قشرة الدماغ. اشارة الرسم الكهربائي للدماغ هي قياس للتيارات المتحركة في قشرة الدماغ. عندما تحفز خلايا الدماغ (العصيبات), يتم توليد التيار الارتباطي في التشجرات العصبية للخلايا. يولد هذا ال | Electroencephalography (EEG) records the spontaneous electrical activity generated in the cerebral cortex. When brain cells (neurons) are active, synaptic currents are produced within their dendrites and this current generates an electrical field over the scalp. The EEG waves measure this current that flow during synaptic excitations of pyramidal neurons' dendrites. Preeclampsia is a disease of pregnancy characterized by a blood pressure of 140/90 mmHg or more on two separate occasions after the 20th gestational week in a previously normotensive woman. This is accompanied by significant proteinuria (>300 mg in 24 hours) and is associated with endothelial cell damage. The markers of endothelial activation or inflammation have been blamed to play an active role in preeclampsia (Sibai et al., 2005). This study included 97 pregnant with a confirmed diagnosis of preeclampsia as a patient group with a gestational age ranging between 20 - 38 weeks. They are divided into three subgroups according to their gestational age (20 - 26 wk, 27 - 32 wk and 33 - 38 wk) and the mean of their age was 29.34±4.82, 30.14±5.33 and 32.54±6.22 years respectively. In addition, 72 women with normal pregnancy have been included as control group. These were also subdivided into three subgroups just like that of the patients and their age matches them too. Participants belong to both patient and control groups had underwent same procedure, examinations and tests like EEG and serological tests for Intracellular Adhesion Molecule 1 (ICAM I), interleukin - 6 (IL6) and C - reactive protein (CRP), in parallel. Results showed that there were statistically significant increased levels (P < 0.05) of ICAMI, IL - 6 and CRP values between patient and control groups and between the patient with mild and those with severe preeclampsia in all tested gestational age subgroups. This supports the hypothesis stating a role of cytokines and inflammatory biomarkers in the mechanism underlying preeclampsia. Moreover, and at all gestational age subgroups, the ICAMI, CRP and IL - 6 values were higher in patients with severe disease when compared with those having milkd disease. This strengthens more the relation of these biomarkers with the progression of preeclampsia. There were abnormal EEG changes in about 52 % of the patients with preeclampsia and these changes were reported in all gestational age subgroups and were in the form of spikes, polyspikes, slow sharp waves. This shows that preeclamptic females are prone to some excessive brain activities that may put them in danger of abnormal brain function. Furthermore, these EEG abnormalities were related to the severity of the preeclampsia as they were recorded in severe cases more and at all gestational age subgroups. Also there were statistically significant elevation regarding ICAMI (at the second and third gestational age subgroups), IL - 6 values (at the second gestational age subgroup) and CRP (at all gestational age subgroups) among patients with and without abnormal EEG changes. This suggests a strong relation between these inflammatory biomarkers with the occurrence of abnormal EEG changes in preeclamptic females. In conclusion, an inflammatory process is blamed to be the underlying mechanism of preeclampsia as proved by the elevated levels biomarkers in these patients. Both the abnormally elevated biomarkers and the abnormal EEG changes occur in preeclamptic patient in different gestational ages above 20 weeks and occur in different disease severity.

Abstract: في هذه الدراسة العرضية, تم اختيار 140 شخصا بصورة عشوائية, من بينهم 90 كان مصابا بالسكري والباقون كانوا سليمين ,لدراسة تاثير ارتداء طقم الاسنان الكلي والجزئي من قبل مرضى السكري على فحوصات كفاءة الرئتين وبالتحديد, , السعة الحيوية القسرية (FVC)و الحجم الزفير | In this cross sectional study, a total number of 140 subjects selected randomly, 90 of them were diabetic and the remaining were normal, to study the effect of complete and partial dentures wearing by diabetic patients on pulmonary function test particularly peak expiratory flow rate (PEFR), forced expiratory volume in the first second (FEV1), forced expiratory volume ratio (FEV1/FVC) ratio (FEV1%), forced vital capacity (FVC), and also the retropharyngeal space (RPS), the level of Endothelial selectin (E - selectin) and the level of Vascular Cell Adhesion Molecule - 1(VCAM - 1)was also compared, in this study, between the diabetic and the normal subjects.The results indicate that the spirolab III was accurate and reproducible and can be used in all related studies.The effect of wearing of complete and partial dentures by diabetic patients on FVC, FEV1, PEFR and also the degree of alteration of the RPS were measured.1) The results of the study shows a significant increase in values of FEV1, FEV1%, PEFR and retropharyngeal space (RPS) (p<0.05), while there was no significant change in the value of FVC after the replacement of complete denture.2) No statistically significant differences in the values of FVC, FEV1, FEV1%, PEFR and retropharyngeal space (RPS) was observed after replacement of partial denture without free end extension3) There was a significant increase in values of FEV1, FEV1%, PEFR and retropharyngeal space (RPS) (p<0.05), never the less there was no significant change in the value of FVC after the replacement partial denture with unilateral free end extension.4) There was a significant increase in values of FEV1, FEV1%, PEFR and retropharyngeal space (RPS) (p<0.05), However there was no significant change in the value of FVC after the replacement partial denture with bilateral free end extension5) The results showed that in poor and good control diabetic patients there was a significant decrease in the values of FEV1, PEFR, FEV1%and RPS after the removal of all types of dentures(p<0.05), while no significant change in FVC.6) Statistical significant increase in Serum E - selectin and VCAM - 1 level was found in diabetic patients when compared to that of the normal subjects (p<0.05).7) No statistical significant difference between serum E - selectin and VCAM - 1 level in diabetic patients after and before denture placement (p>0.05). The cause of the significant change in the values of FEV1, FEV1%, PEFR and retropharyngeal space (RPS) in case of complete and partial denture with free end extension replacement may be due to pressing of the retropharyngeal space bilaterally and unilaterally by the complete and partial denture and the FVC was not significantly changed because it may not be affected by denture support, while the elevated Serum E - selectin and VCAM - 1 level might indicate endothelial activation and inflammation.In conclusion we can conclude that 1. The spirolabIII used in this study is an accurate and reproducible device and can be used in the assessment of lung function test.2. Values of FEV1, FEV1%, PEFR and retropharyngeal space (RPS) where significantly higher after the replacement of complete denture and partial denture with bilateral and unilateral free end extension in diabetic patients (p<0.05), while there was no significant change in the value of FVC.3. No statistically significant differences in the values of FVC, FEV1, FEV1%, PEFR and retropharyngeal space (RPS) was observed after partial denture without free end extension has been replaced in diabetic patients.6. In poor and good control diabetic patients there was no significant change in the value of FVC, while the values of FEV1, PEFR, FEV1%and RPS where significantly decrease after the removal of all types of dentures.8. Statistical significant increase in Serum E - selectin and VCAM - 1 level was found in diabetic patients when compared to that of the normal subjects.9. The results for serum level of E - selectin and VCAM - 1 shows no significant difference diabetic patients after the placement of all types of dentures (p>0.05).

Abstract: الخلفية : الاعتلال العصبي اللاارادي القلبي له تاثير سلبي على الحياة ونوعيتها للاشخاص المصابين بالسكري. الاعتلال العصبي اللاارادي القلبي يعتبر نوع فرعي من الاعتلال العصبي السكري. هذا النوع من الاعتلال هو الاكثر بروزا لتهديده للحياة وبسبب توفر الفحص القلبي | Background : Cardiac autonomic neuropathy (CAN) has a negative effect on survival and quality of life in people with diabetes mellitus (DM) and is regarded as a subtype of the diabetic autonomic neuropathy. This type of neuropathy is the most prominent focusing because of its life threatening and the availability of the cardiovascular tests that can diagnose it. It has been thought that many factors in DM like leptin causing increase the risk of cardiovascular disease. Researches about the relation of leptin with CAN and cardiovascular disease are yet limited.Aim of study : This study aims to determine the prevalence of CAN in patients with type 2 diabetes mellitus, evaluate the association between CAN the presence of left ventricular dysfunction in these patients, test the association between CAN and ischemic heart disease and assess the relationship between the presence and severity of CAN with fasting serum leptin in these patients.Patients, materials and methods : This cross sectional study included 103 (56 males and 47 females) diabetic patients without hypertension or pre - diagnosis of ischemia. They had attended to the diabetic center in Marjan Medical City in Hilla from March 2013 to February 2014. The patients had undergone thorough assessments that included clinical (history and full examination) and biochemical assessments (measurement of fasting plasma sugar, glycated haemoglobin, lipid profile, blood urea, serum creatinine and serum leptin level). Cardiac autonomic reflex tests were also assessed along with echocardiography and treadmill test. Cardiac autonomic reflex tests included the five tests of Ewing protocol. Patients who had two or more abnormal tests were considered as having CAN (75 patients) and those with less than two abnormal tests were considered as patients without CAN (28 patients). Results : The study found that most diabetic patients (84%) were obese (BMI?25 kg/m2) and most of the diabetic patients presented with CAN (72.8%). Fasting serum leptin level was higher in female than in male in both study groups (with and without CAN). Patients with CAN were older when compared to patients without CAN (p?0.01) and had longer duration of DM (p?0.01) with significantly higher fasting serum leptin levels. The leptin level showed a tendency to increase as the score of CAN increased. However, these changes were not significant (P>0.05). The most abnormal sympathetic response was diastolic blood pressure response to hand grip while the most abnormal parasympathetic response was heart rate response to breathing. On contrary, the lowest abnormal response was found in postural blood pressure test. Echocardiography showed that most of the diabetic patients (89.8%) had a left ventricular hypertrophy by measuring the left ventricular mass index. However, there were no significant changes in echocardiographic results between patients with CAN and those without.Conclusions : This study concludes that CAN is a common complication of type 2 diabetes that affected a large percentage of diabetic patients. The duration of the diabetes and the age of patients are important non modifiable risk factors for the development of CAN. Additionally, heart rate variability is considered as an important test for early detection of CAN. On the other hand, CAN has no impact on the occurrence of left ventricular diastolic dysfunction. Leptin level was high in diabetic patients and even higher in those with CAN and its levels related positively with the severity of CAN. Also, there were high leptin levels in diabetic patients with positive treadmill test results, although these changes were not significant (P>0.05).
