Perception of peer teaching on learning anatomy: A qualitative study.

The aim of this study was to identify the effectiveness of peer-assisted learning while giving presentation on assigned anatomy topics in class by medical students for enhancement of their learning and communication skills. Sixty top performing students were selected for the study. They were given assigned topics related to anatomy to be presented in the class after taking their consent. The duration of the study was 32 weeks. At the completion of the projects by the students, each of them was interviewed for three to five minutes; the questions were very precise and few in number and were then analysed. Focus group discussions were conducted from the rest of the class who were the audience and enjoyed the activity. The study showed that by conducting such an activity among medical students their knowledge about the subject, communication and teaching skills and confidence are enhanced. It is a fun activity for them and can be added in the routine timetable for its beneficial outcomes.

Gene expression of Interleukin-18 in rheumatoid arthritis patients on disease modifying anti-rheumatic drug therapy.

BACKGROUND & OBJECTIVES: The hallmark of rheumatoid arthritis is the inflammation that is mediated by the macrophages and monocytes that cause release of pro-inflammatory cytokines like interleukin-18. It is highly expressed in serum of patients suffering from rheumatoid arthritis and has a positive association with disease activity. The aim of this study was to analyze the gene expression of interleukin-18 in rheumatoid arthritis patients on disease modifying anti-rheumatic drug therapy. METHODS: The cross sectional comparative study is conducted at Department of Biochemistry and Molecular Biology and Center for Research in Experimental and Applied Medicine (CREAM-1Lab), Army Medical College, Rawalpindi, in collaboration with Rheumatology Department, Military Hospital, Rawalpindi. Study was conducted on two groups consisting of Group-I of rheumatoid arthritis patients on diseases modifying anti-rheumatic drugs and control Group-II comprising of normal healthy individuals. Non-probability purposive sampling was done from patients and controls. The duration of study was one year i-e from November 2015 to November 2016. Relative quantification of gene expression of interleukin-18 was done by Real time PCR using ∆∆CT method. RESULTS: Expression analysis for interleukin-18 showed down regulation of gene in rheumatoid arthritis patients as compared to controls. CONCLUSION: Interleukin-18 gene shows down regulation in rheumatoid arthritis patients on disease modifying anti-rheumatic drugs therapy.

Expression of Estrogen Receptors (ER), Progesterone Receptors (PR) and HER-2/neu receptors in Endometrial Carcinoma and their associations with histological types, grades and stages of the tumor.

OBJECTIVE: To study and detect immunohistochemical expression of Estrogen Receptors, Progestrone Receptors and HER-2/neu Receptors in Endometrial Carcinoma (EC) and to find their associations with histological types, grades and stages of the tumor. METHODS: A cross sectional study of one year duration from January 2016 to January 2017 was conducted at Histopathology department of Army Medical College, Rawalpindi. A non-probability purposive sampling technique was used to include 56 cases of EC. The specimens were tested for ER, PR and HER-2/neu expression using immunohistochemical analysis. Data was analyzed in SPSS and the significance of association of expression of the receptors with histological types, grades and stages of the tumor was assessed. RESULTS: Significant association of Her-2/neu overexpression with histological types and grades of EC was seen, whereas the association of ER and PR expression with histological types, grades and stage of EC was statistically insignificant. CONCLUSION: It is suggested that EC showing over expression of HER2/neu with immunohistochemistry may be treated with anti HER-2/neu treatment with better chances of survival and decreased post-treatment morbidity.

Usefulness of needle biopsy in the diagnosis of paediatric liver disorders.

OBJECTIVE: To see the usefulness of liver biopsy in the diagnosis and to document the spectrum of paediatric liver diseases. METHODS: A retrospective, cross sectional survey at Histopathology Department of Army Medical College Rawalpindi from January 2000 to December 2003. The liver biopsies were taken with Menghini needle. The fixed tissues were processed under standard conditions. RESULTS: During four years period, a total of 100 cases with age range of 1.5 months to 16 years were studied. The most common histological findings in order of frequency were secondary haemochromatosis (30%), biliary atresia (20%), storage disorders (16%), cirrhosis of liver (10%) and neonatal hepatitis (10%). The less common entities were chronic hepatitis (6%), nonspecific reactive hepatitis (3%) and granulomatous hepatitis (1%). One case each of hepatoblastoma, haemophagocytic lymphohistiocytosis and congenital fibrosis was also noted. These findings have been compared with local and international histological studies. CONCLUSION: Liver biopsy is a useful diagnostic technique in the diagnosis of paediatric liver diseases. Biliary atresia, strorage disorders and neonatal hepatitis are the most common entities in our set up.

Morphological features correlation with serum tumour markers in prostatic carcinoma.

OBJECTIVE: To find out Gleason grades, scores and to see the correlation of these morphological features with tumour markers in prostatic carcinoma. DESIGN: A descriptive study. PLACE AND DURATION OF STUDY: The study was conducted at the Departments of Histopathology and Chemical Pathology, Armed Forces Institute of Pathology, Rawalpindi, over a period of one year. MATERIALS AND METHODS: Fifty cases of prostatic carcinoma were studied. Gleason grades and score of tumour were determined by doing haematoxylin and eosin (HE) staining. Pre-operative serum prostatic acid phosphatase (PAP) and prostate-specific antigen (PSA) assays were carried out in these cases. RESULTS: The patients seen were between 50-102 years of age with an average of 70.9 years. There were 49 cases of adenocarcinoma and 01 case of mixed adeno and transitional cell carcinoma of prostate. Twenty-eight (56%) patients had Gleason score of 5-7. Twenty-nine (58%) patients were having serum PSA levels between 10.0 ng/ml and 50.0 ng/ml. Thirteen (26%) cases showed PSA assays >50 ng/ml. The sensitivity of PSA test was 84 % in these cases. Thirty-five (70%) patients were having PAP values >3.7 U/l (sensitivity 70 %). CONCLUSION: The Gleason grading system is a specific morphological predictor. The serum PSA showed better sensitivity and specificity with Gleason grades and scores as compared to serum PAP. The serum PAP levels showed better correlation with morphological features as compared to serum PSA.
