Background: Urine cytology has an acceptable sensitivity, & specificity that justifies its use in the current diagnostic protocol. In Iraq transitional cell carcinoma (TCC) constitute about 62.1 % of bladder cancer (which ranks the third according to the results of Iraqi Cancer Registry 1995-1997). Urine cytology used in the primary diagnosis, follow up, and in the screening programs of asymptomatic but high-risk patients.
Patients and methods: This study was conducted on 93 patients, diagnosed or clinically suspected to have TCC of the urinary bladder attending to the Urological department in ALKadhimiya Teaching Hospital, AL-Yarmouk Teaching Hospital, and Baghdad Medical City. During the period from July 2004to July 2005. 76 were males & 17 were females.
Urine cytological examination was done to those patients using two types of stain (hematoxylin and eosin, and papanicoloau stain) to detect malignant cells with the identification of the degree of differentiation, if possible, the cytological findings were correlated with the histopathological findings. And the cytological findings compared regarding each type of stain.
Results:. Mean age of the patients was 59 year. Male:female ratio was 4.4:1. Main clinical presentation was hematuria (45.8%) of the total. Urine cytological examination has a sensitivity of 87.7%, specificity of 100% with an overall accuracy of 78% in the detection of TCC of urinary bladder. The main chief complaint of patients with TCC was haematuriawitch constitute 45.8% of the total. The percentage of highgrade cases in urine cytology was higher than that in histopathology.the percentage of cases of TCC diagnosed by papanicoloau stain was more than that diagnosed by H & E (73.24% by pap stain versus 70.42% by H&E).
Conclusion: Urine cytology has an acceptable sensitivity, specificity and an overall accuracy in the diagnosis of TCC of urinary bladder, and it offers a good chance for determination of the grade of the tumor especially in high grade tumor. Pap stain was better in the diagnosis of TCC.
The current research aims to evaluate the appraisal form for Arabic language teachers in light of comprehensive quality standards by designing standards for the competencies of primary school teacher in accordance with comprehensive quality requirements. The researcher adopted the descriptive approach. The research community included the Arabic language supervisors in the Education Directorates of Diyala Provincial and Baghdad. The research sample consisted of (14) supervisors from the Diyala Provincial Department of Education and the First Rusafa Education Directorate in Baghdad Governorate by (8) supervisors and (6) Supervisors respectively specializing in Arabic language. As for the research tool, questionnaire prepared by the researc

Show MoreThe activity of Alanine aminopeptidase( AAP ) was measured in the urine of healthy and urinary tract cancer patients , the results showed higher activity of (AAP) in patients compared to healthy . AAP was Purified from the urine of healthy and patients with urinary tract cancer by dialysis and gel filtration (Sephadex G – 50) and two isoenzymes of (AAP) were separated from urine by using ion-exchang resin (DEAE – Sephadex A – 50 ) in previous study. The kinetics studies showed that both isoenzymes I and II obeyed Michaelis – Menton equation . with optimal concentration of alanine-4-nitroanilide as substrate for isoenzymes I and II which was (2 x 10-3 mol/L ). The two isoenzymes obeyed Arrhenius equation up two 37° C and t
... Show MoreTwo isolates of Staphylococcus xylosus (urease producer and non urease producer) were injected in mice at a dose of 2 × 108 colony-forming units (CFU) intraurethrally. Results showed that both isolates were able to colonize kidney and bladder of the injected mice, regardless of their urease production. Moreover, there were insignificant differences between the two groups. These results emphasized the pathogenicity of this bacteria in UTI.
Background: Oral squamous cell carcinoma continues to be a major health problem in Iraq as well as in other countries. Many attempts were made to study molecular markers in oral squamous cell carcinoma and to link them to tumor grade, stage and prognosis, besides studying their role in carcinogenesis. The present study has been designed to detect mRNA of c-myc in oral squamous cell carcinoma compared to oral dysplasia and to link the marker to grade and degree of the two pathologies.
Materials and methods: Forty two cases, including 30 cases of oral squamous cell carcinoma and 12 cases of oral dysplasia were included in this study. Sections on positively charged slides were made from their paraffin blocks
Background: Salivary biomarkers, a non-invasive alternative method to serum and tissue based biomarkers and it is consider as an effective modality for early diagnosis. Salivary microRNA 21, a nucleotide biomarker, was reported to increase in patients with oral squamous cell carcinoma. This study was conducted to measure the fold change of microRNA 21 in stimulated saliva and to study its association with smoking and occurrence of oral squamous cell carcinoma. Materials and methods: A 20 patients with oral squamous cell carcinoma who used to be smokers was included in addition to 40 control subjects (20 smokers and 20 non- smokers health looking subjects). Stimulated saliva was collected under standardized condition. Salivary microRNA 21 wa

The aim of this study is to evaluate the Immunohistochemical expression MMP-2, VEGF and D2-40 expression in OSCC and VSCC. Materials and methods: Thirty formalin fixed paraffin embedded tissue blocks of OSCC and another twelve VSCC were collected and Four micrometer thick sections were cut from each block and mounted on positively charged slides and stained immunohistochemically with monoclonal antibodies to MMP-2, VEGF and D2-40. Results: there is no statistical difference between SCC and VSCC regarding the immunoexpression of MMP-2 and VEGF. While the lymphatic vessels density were higher in SCC than V

Show MoreA study that collected 240 samples and divided into two groups: the first 120 samples were for diabetics and the second 120 samples were for healthy people, and each group included (90, 20.10) samples from the mouth, urine and vagina respectively, The results showed positive (28.67, 4.00, 1.67) isolates of Candida. In the mouth, urine and vagina, respectively, of diabetic patients compared to (9.33, 2.33, 5.00) positive isolates in the mouth, urine and vagina, respectively, in the healthy. The rate of positive isolates in women was high in women with diabetes and healthy, and it reached 25.33 and 9.00 isolates, respectively, compared with the rate of isolates in men with Candida disease for diabetic patients and healthy people 14.67 and 2.0
... Show MoreAutomated medical diagnosis is an important topic, especially in detection and classification of diseases. Malaria is one of the most widespread diseases, with more than 200 million cases, according to the 2016 WHO report. Malaria is usually diagnosed using thin and thick blood smears under a microscope. However, proper diagnosis is difficult, especially in poor countries where the disease is most widespread. Therefore, automatic diagnostics helps in identifying the disease through images of red blood cells, with the use of machine learning techniques and digital image processing. This paper presents an accurate model using a Deep Convolutional Neural Network build from scratch. The paper also proposed three CNN
