المستخلص: Total no. of patient (100) stool samples were collected, during the period from February to the end of May of 2008, for children under two years old suffering from non-bloody and bloody diarrhea at (Children Welfare Teaching Hospital) in Baghdad.
The study evaluates the relationship between etiological agent of diarrhea and sex, age group, type of feeding, presence of blood in stool of the patients. All samples were examined microscopically to identify parasitic agent and serological test for Rotavirus to identify viral infection, also biochemical and serological tested for specimen's culture on different culture media and antibiotic sensitivity test.
Results show from 100 cases 64] represents the etiological agent of diarrhea and the most common of this agent was Rotavirus represent (37.5 %), respectively then Entamoeba histolytica (21.9 %), other agents were include Proteus (12.5 %), Enteropathogenic E.coli (10.9 %), Citrobacter braakii (7.8 %), Salmonella typhi (6.3 %), and Giardia lamblia (3.1 %). The remaining 36 isolates represent of unknown etiological agent for another's pathogen.
The prevalence ratio of infection in male (75.0 %) was more than in female (25.0 %), in the first year of age especially in the age group (0-6) months (42.2 %). children depending on artificial feeding represent about (57.8 %) higher natural and mixed feeding, the bloody diarrhea associated with Entamoeba histolytica (57.1 %) in contrast to some etiological agent of non-bloody diarrhea.
Eleven types of antibiotics were used for sensitivity test show all serotype of Enteropathogenic E.coli and Salmonella typhi are sensitive to Imipenem and Ciprofloxacin. The predominant serotypes of Enteropathogenic E.coli which represent serotype O111 and serotype O125 these strains show resistance to Cefotaxime (CTX), Trimethoprim-sulfamethaxazole (SXT), Ampicillin (AM), Metronidazole (MET), Cefoperazone (CEP), Cefixime (CFM), also the serotype O111 resistance to Gentamicin (CN) represent (45.0 %), while the most resistance of Salmonella was to Amikacin (100.0 %).
This may reflect the fact that the increased resistance in older children and adult may be associated with the development of immunity or the loss of receptors for some specific adhesion.
In Iraq Rotavirus infection is estimated to account for (10-29 %) in early childhood, While in neighboring countries the rate ranges between (19-46 %). The study show infected males more than female and the highest diarrheal infection was caused by Rotavirus, the Imipenem and Ciprofloxacin antibiotic was the most effective one against pathogenic strains of Enteropathogenic E.coli and Salmonella typhi while all isolates were resistant to Trimethoprim-Sulfamethaxazole, Ampicillin, Metronidazole.

المستخلص: This study was conducted to detect the invasive aspergillosis inimmunocompromised patients with rapid diagnostic method (ELISA).This study was conducted on 50 immunocompromised patients, theywere the attendants of Hematology / Oncology Department of BaghdadTeaching Hospital, pediatric oncology wards. The patients presented withfever which is not responding to antibiotics along with cough and sputumand abnormality on chest x - ray . And 11 healthy Iraqi individuals wereincluded in this study. from March 2013 till October 2013.Sputum and serum. initially direct microscopical examination donefor each sample and stained with gram stain. Sputum was immediatelycultured on Sabouraud dextrose agar (SAB) and Brain heart infusion agar(BHI) labeled with same code number of that sputum. Wet preparationwas down from colonies on Sabouraud dextrose agar plate or Brain heartinfution agar for isolation and identification of species of growingmould.This study showed that female to male ratio among patients studygroup was (1.2 : 1) .The age of the patients ranged from from 2 to 70 years with a meanage (31.8 ± 0.8) years. For the control the age ranged from 11 to 60 yearswith a mean age (31.1 ± 0.1) years. The peak mean age group (10 - 20)years with (5.1 ± 0.1).This study showed that 33( 66%) of patients were havingneutropenia which it is highly significant = 11.58 when the P value(P<0.01) , 10 ( 20% ) of patients were having neutrophilia and 7 (14%)of patients were having normal blood film results.IIThis study showed that sputum culture for Aspergillus positive in 18cases and it was negative in 17 patients, it was not done in 15 casesbecause some are from patients were sputum sampling was difficult to beobtained (pediatric), or have no sputum . And the Aspergillus speciesisolated from this culture showed that Aspergillus fumigatus is the most common species isolated from sputum culture 11 (61.1%) of positive culture results.The results showed high significant of AML diseases which composed 18 of 50 (36%) of patients , and most of the patients 24 of 50 (48%) of patients were on amphotericin B treatment.The results of the detection of galactomannan antigen detected by ELISA showed that the difference between the mean cutoff value of the patients and the control group was statistically significant (T = 0.135 and P value <0.05). In patient study group the ELISA test was positive in 39 of 50 (78% ) which it is highly significant when compared with noncancerous control group who were all negative 11 of 11 (100%) at p - value <0.001.Finally this study showed that (28 of 50) 56% of patients were dead because they are have invasive pulmonary aspergillosis (IPA) which is serious and potentially fatal disease that might kill the patients if any delay occurs in lab. diagnosis. So early diagnosis of invasive pulmonary aspergillosis may give higher cure rates.

المستخلص: الداء الزلاقي هو مرض مزمن، يحدد مناعيا من شكل الاعتلال المعوي الذي يؤثر في الامعاء الدقيقة عند الاطفال والبالغين ذوالميول الوراثي . وتظهر بشكل سريع عند ابتلاع الاطعمة التي تحتوي على الغلوتين. ويشار ايضا الى انه ذرب الاضطرابات الهضمية والحساسية من الغلوتين في الامعاء او غير ذرب الاستوائية. يمكن تعريف الغلوتين بانه كتلة البروتين المطاط الذي يبقى عندما يتم غسل عجين القمح لازالة النشا. مكونات البروتين الرئيسية في الغلوتين (غليادين وغلوتينين) وهي بروتينات التخزين في الحنطة. استجابة الخلايا المناعية للغليادين تشمل زيادة التعبير من المستقبلات السطحية. بعض من هذه المستقبلات تشمل HLA - DR ، جزيء التصاق ما بين الخلايا ، CD3 ( في خلايا Tالناضجة ) ، CD25 وCD69 ( في خلايا T المنشطة والخلايا القاتلة الطبيعية ) .هدف هذه الدراسة هو التحقيق في القيمة السريرية لستخدام علامات CD في تشخيص الداء الزلاقي . اشتملت هذه الدراسة على 40 مريضا (21 من الذكور و19 من الاناث) مصابين بالداء الزلاقي حضروا مستشفى الجهاز الهضمي والكبد التعليمي في مدينة الطب ، وخلال الفترة ما بين فبراير 2013 الى حزيران 2013. كذلك تالفت مجموعة السيطرة من 40 شخصا اصحاء الذين لم يشكو من اي مشكلة في الجهاز الهضمي. وتم اخذ عينات من الدم الوريدي لكل شخص ( الدماء الجديدة لاجراء اختبار الكشف عن العلامات السطحية باستخدام تقنية التدفق الخلوي والامصال لاجراء اختبار tTG الاضداد الذاتية باستخدام تقنية الاليزا ) . هذه الدراسة بينت ان اعمار المرضى المصابين بالداء الزلاقي في هذه الدراسة قد تراوحت ما بين سنتين الى ستة وخمسين سنة وبمتوسط عمر (15.6 ± 13.1) سنة. انخفاض مستوى الدم من خلاياT اللمفاوية الموجبة لعلامة CD3 بشكل ملحوظ في الحالات ( المرض الزلاقي ) التي تراوحت بين (7.6 - 62.3) بمتوسط (36.8 ± 16.7) مقارنة مع مجموعة السيطرة التي تراوحت بين (4.4 - 62.1) بمتوسط (41.9 ± 16.9). في حين ان مستوى الدم من خلايا T اللمفاوية الموجبة لعلامة CD6بزيادة كبيرة في مجموعة الحالات التي تراوحت بين(1.8 - 25.6) بمتوسط (10.5 ± 5.1) بالمقارنة مع مجموعة السيطرة التي تراوحت بين(1 - 9.4) بمتوسط (3.6 ± 2.2) . كما اثبتت الدراسة الحالية ان هناك فروقات ذات دلالة احصائية في مستويات المصل الذي يحتوي اضداد ذاتية tTG - A (p < 0.001) والمصل الذي يحتوي اضداد ذاتية tTG - G (p < 0.007) بين الحالات والسيطرة. اخيرا استنتجنا ان علامة CD69 هي اداة دقيقة لتشخيص اولي للداء الزلاقي . كذلك هناك ارتباط كبيربين كل من المصل الذي يحتوي اضداد ذاتية tTG - A والمصل الذي يحتوي اضداد ذاتية tTG - G مع خلايا Tاللمفاوية الموجبة لعلامة CD69 في المرضى الذين يعانون من الداء الزلاقي | Coeliac disease is a chronic, immunologically determined form of enteropathy affecting the small intestine in genetically predisposed children and adults. It is precipitated by the ingestion of gluten - containing foods. It is also referred to as coeliac sprue, gluten - sensitive enteropathy, or non tropical sprue. Gluten can be defined as the rubbery protein mass that remains when wheat dough is washed to remove starch. The major protein components of gluten—gliadin and glutenin—are storage proteins in wheat. The response of immune cells to gliadins includes the increased expression of surface receptors. Some of these receptors include HLA - DR, intercellular adhesion molecule, CD3 (in mature T - cells), CD25 and CD69 (in activated T - cells and natural killer cells). This study conducted to investigate the clinical value of using CD markers in diagnosis of coeliac disease. A total of 40 patients (21 males & 19 females) with coeliac disease attending the Gastroenterology and Hepatology Teaching Hospital in the Baghdad Medical City, during the period between February 2013 - June 2013.The control group consisted of 40 apparently healthy individuals who were not complaining of any gastro - intestinal problem. Venous blood samples were taken from each subject (fresh blood tested for detection of surface markers by flow cytometry and sera tested for Anti - tissue transglutaminase auto - antibodies by Enzyme Link Immune Sorbent Assay).This study shows that the age of coeliac disease patients in this study was ranged between (2 - 56) years with the mean age of (15.6 ± 13.1) years. Blood level of CD3 positive T - lymphocytes was not significantly decreased in cases group that ranged between (7.6 - 62.3) with mean (36.8 ± 16.7) when compared with controls group that ranged between (4.4 - 62.1) with mean (41.9 ± 16.9), While the blood level of CD69 positive T - lymphocytes was significantly increased in cases group that ranged between (1.8 - 25.6) with mean (10.5 ± 5.1) when compared with controls group that ranged between (1 - 9.4) with mean (3.6 ± 2.2). Also the current study has been demonstrated that there were a statistical significant difference in the serum levels of tissue transglutaminase - A auto - antibodies (p < 0.001) and tissue transglutaminase - G auto - antibodies (p < 0.007) between cases and controls. Finally this study concluded that CD69 marker is an accurate tool for the diagnosis of coeliac disease. There were significant correlations between each of Serum tTG - A auto - antibodies and Serum tTG - G auto - antibodies with CD69 positive T - lymphocytes in coeliac disease patients.

المستخلص: One - hundred and twenty samples ( corneal scraping) were collected from patients diagnosed to have microbial keratitis (corneal ulcer) who attended Ibn Al - Haitham Teaching Eye Hospital from the period between May 2013 and November 2013, Pseudomonas aeruginosa was reported 26 (21.6%) from the total cases. All bacterial isolates were diagnosed by conventional and biochemical tests, and confirmed by Vitek 2 Compact System.The role of proteases enzymes ( Elastase ( LasB), LasA, Alkaline protease and Protease IV ) of Pseudomonas aeruginosa in the corneal ulcer was studied by using genetic and molecular biological method by real time PCR, and the results indicated that three bacterial isolates of Pseudomonas aeruginosa possessed elastase gene (LasB) (11.5%), and only one bacterial isolate of Pseudomonas aeruginosa harbored LasA protease gene ( 3.8%). All bacterial isolates of Pseudomonas aeruginosa were harbored alkaline protease gene (100%), and twenty bacterial isolates were harbored protease IV (76.9%).The results of real - time PCR analysis indicated that four bacterial isolates of Pseudomonas aeruginosa (15.3%) were harbored more than one gene of different proteases enzymes ( elastase, alkaline protease, and protease IV).On the other hand our results showed that one bacterial isolates (3.8%) harbored both LasA protease and alkaline protease genes, and twenty bacterial isolates of Pseudomonas aerugenosa (76.9%) were harbored alkaline protease and protease IV genes.The LasA protease was extracted from Pseudomonas aeruginosa isolate by cooling centrifuge and precipitated supernatant by ammonium sulfate at saturation (80%). The resulted extracted crude enzyme concentration was 60 μg/ml. Then the crude enzyme was partially purified by dialysis and gel filtration chromatography by using Sephadex G - 100. The concentration of partial purified enzyme reached 40μg/ml.IIISummaryThe results of the experimental treatment of bacterial keratitis ( in vivo) of infected eyes rabbits caused by Methicillin Sensitive Staphylococcus aureus showed that the efficacy of LasA protease was effective was as Lysostaphin in eradicating Methicillin Sensitive Staphylococcus aureus from the infected corneas after approximately 15 h after giving the drug at dose 100 μl ( concentration 1μg / ml ) . While Vancomycin gave us very little potency in eradicating S. aureusfrom corneas in comparison with potency of LasA protease and Lysostaphin duringthis time but showed good potency very late approximately after 3 days of applicationof treatment.The results of the experimental treatment in vitro (in the test tube ) that is caused by Methicillin Sensitive Staphylococcus aureus showed that the efficacy of LasA protease was similar to that of Lysostaphin drug in the killing of Methicillin Sensitive Staphylococcus aureus in the bacterial broth.

المستخلص: Colonic cancer is a very common disease world - wide being fourth most common cancer characterized by abnormal proliferation of the epithelium of colon at beginning then taking full colon wall thickness then to surrounding lymph nodes and tissues and finally metastasis. It is one of most complicated diseases with debilitating symptoms which becomes more severe, prominent and specific with advancing stage with high percent of fatality and relatively short survival if diagnosed late or if left untreated.Therefore, finding an easy, non - invasive and readily available means (marker) of screening and diagnosing colonic cancer would be of great value particularly if the same biomarker can be used for diagnosis, screening, prognosis and monitoring the efficacy of different treatment modalities.Aims of study : - To investigate the efficacy and validity of serum Cancer Antigen 19 - 9 (CA19 - 9) and Colon Cancer Specific Antigen - 4 (CCSA - 4) levels in the screening and prognosis of colon cancer and their validity for this.Patients and methods : - This study was applied on 35 patients (17 females & 18 males) with colon cancer with ages ranged 53 - 82 years old ( 6 patients received chemotherapy and 5 of them have undergone surgical removal of the primary tumor and 4 different patients received immunotherapy) with 20 smokers and 4 alcoholic, 35 patients (19 females & 16 males) with benign polyps ages ranged 29 - 56 years old and 16 (7 females & 9 males) negative controls ages ranged 25 - 43 years age. According to DUKE's staging : 6 colon cancer patients were stage A, 12 were stage B, 12 were stage C and 5 were stage D.All individuals in this study (whom attended Baghdad Teaching Hospital and Gastroenterology and Hepatic Diseases Center) were subjected to blood sampling for measuring their serum CA19 - 9 and CCSA - 4 using Enzyme Linked ImmunoSorbent Assay (ELISA) technique which was done at microbiology unit / university of Baghdad.Results : - The present study has shown that colonic cancer patients were presented at ages between 53 - 82 years of age (mean 68.5±6.4 years of age).Serum levels of CCSA - 4 were significantly elevated in those patients with advancing stages (C & D) compared with stages (A & B) and lower levels found in patients who had surgical removal of tumor or received chemotherapy.Also a positive relation found between CCSA - 4 with alcohol intake and smoking, however, less significant levels and relations found with CA19 - 9.Conclusion : - Serum CCSA - 4 is sensitive and specific indicator for diagnosis, prognosis and screening of colonic cancer.
