Objective: The aim of this study was to determine the diagnostic accuracy of biopsy-based tests in the detection of Helicobacter Pylori infections keeping histopathology as a gold standard. Materials and Methods: This validation study was conducted from August 2018 to February 2019 at Khyber medical college, pathology department, Peshawar, and comprised biopsy samples of 87 patients obtained via endoscopy which was done at the gastrointestinal endoscopy department, Hayatabad medical complex (HMC). Patients with a history of prior antibiotics and PPIs were excluded from the study. Rapid urease test (RUT) and culture of gastroduodenal biopsies were validated against the histopathological examination of gastroduodenal mucosa. Results: Out of 87 patients, 57.47% (50/87) were male and 42.52% (37/87) were female patients with an age range of 18 -80 years and a mean age of 45 years. Endoscopic findings showed 64.36% (56/87) of patients with gastritis, duodenitis with 6.89% (6/87), peptic and duodenal ulcers with 22.98% (20/87), erosion with 4.59% (4/87) and adenocarcinoma of stomach with 2.29% (2/87). The sensitivity and specificity of culture were 45.45% and 90.7% respectively, while positive and negative predictive values were 62.5% and 83% respectively. The sensitivity and specificity of the rapid urease test (RUT) were 81.81% and 90% while positive and negative predictive values were 90% and 94% respectively. Conclusion: The sensitivity and specificity of the rapid urease test were 82 and 90% respectively, while that of culture was 45 and 91% respectively.

Objectives: To determine the pattern of histological findings in prostatic chips obtained from cases of enlarged prostate gland and to correlate the findings with PSA levels. Materials and Methods: It was a cross sectional descriptive study conducted in Northwest General Hospital , Peshawar from 1st January 2018 to 23rd December 2021. A total of 500 male cases with features of enlarged prostate, frequency, urgency and dribbling with mean age of 52 ± 12.3 years (range 45 -80 years) were included in the study. The prostatic biopsy specimens were obtained and PSA levels were done in all cases. The histological specimens were subjected to microscopic examinations and findings were recorded in proforma. The findings were correlated with the PSA levels. Mean and standard deviation were used for quantitative data. Frequency and percentages were used for qualitative data Results: Out of 500 cases of enlarged prostate, benign prostate hypertrophy was seen in 375 (75%) cases. 125 cases (25%) had micro invasive carcinoma prostate . All 375 cases of benign prostate hypertrophy had prostate specific antigen levels less than 4ng. Out of 125 cases of micro invasive carcinoma, 120 (96%) had PSA levels >10ng . Sensitivity of PSA at levels of 10ng/ml for prostatic carcinoma was 96%. Conclusion: Benign prostate hypertrophy is the commonest lesion in cases of prostate pathology. PSA is useful marker to determine the presence or absence of micro invasive carcinoma in patients with prostate hypertrophy. Keywords: Benign prostate hypertrophy, micro invasive carcinoma prostate, prostate specific antigen.

Objective: The objective of this study is to find out protective effect of olive oil to prevent bone loss by decreasing osteoclast count in patient receiving Anastrazole. Study Design: Experimental study. Setting: Pakistan Council for Scientific and Industrial Research (PCSIR) Animal House, Peshawar and Pathology Lab KGMC Peshawar. Period: March 2019 to December 2019. Material & Methods: Sixty female albino mice 6-8 weeks of age were selected for this experimental study and Aromatase inhibitor drug Anastrazole was given alone and in combination with olive oil once daily for 30 successive days. Femur bone samples were collected and stained with Eosin and Hematoxylin for histomorphological evaluation of osteoclast cell count in three all three groups i.e. control group, those receiving Anastrazole alone and those given Anastrazole and olive oil in combination. Results: The mean weight of all experimental female albino mice before study was 30.77- 33.05 grams and after the study was 30.84- 21.31 grams. Control group 1 which was given normal diet showed increased weight of mice with less osteoclast cell count as compared to experimental groups (2 and 3).  In group 2 (Drugged) which was given Anastrazole, weight of were lesser than control group 1 and group 3(Anastrazole + olive oil), while, osteoclast score was greater than group 1(control) and group 3 (Anastrazole + olive oil). Group3 (Drugged+ Olive oil) showed greater weight of mice than group 2 (Anastrazole) but, lesser than control group 1. Osteoclast score was greater than control group but lesser than group 2 (Anastrazole). Conclusion: The results showed positive and protective effects of olive oil against Anastrazole induced bone loss in female albino mice.
