Publication Comparative attitude and plans of the medical students and young Nepalese doctors(Kathmandu University, 2009) Lakhey, M; Lakhey, S; Niraula, SR; Jha, D; Pant, RAbstract Introduction: Many doctors are leaving Nepal to work abroad. To understand this problem better, we decided to study the attitude and plans of young doctors and medical students. Materials and methods: This cross-sectional study was conducted at Kathmandu Medical College involving 65 first- year medical students, 100 interns and 100 house officers. The data collected was entered in Microsoft excel and analysed by SPSS (Statistical Package for Social Sciences) programme. Chi-square test was used to compare two proportions. Significance level was set at 5%. Results: Only 2% house officers said that their job prospects were excellent as compared to 22.4% of students, whereas 20% house officers as compared to 9% students thought job prospects in Nepal were poor (p= 0.003). Eighty two percent of students thought that a doctor’s service to his country was very important as compared to 51% of interns (p=‹ 0.001) and 58% of house officers. Forty percent of students, 58% of interns and 48% of house officers (no statistical significance between the three groups) planned to migrate to a developed country after graduation. Eighty eight percent of students, 89% interns and 74% of house officers (no statistical significant differences between the three groups) were of the opinion that improving career opportunities or working environment of the doctor could make the profession more attractive. Conclusion: Although majority of students, interns and house officers were of the opinion that a doctor’s service to his community/country was very important, almost half of them still planned to migrate to a developed country after graduation. Improving the chances of professional advancement and professional working environment can make the profession more attractive, and therefore, may decrease this tendency for brain drain from our country. Key words: Attitude, medical students, migration, young doctors, statistical significance.Publication Correlation of serum free prostate-specific antigen level with histological findings in patients with prostatic disease(Kathmandu University, 2010) Lakhey, M; Ghimire, R; Shrestha, R; Bhatta, ADAbstract Background: Prostate Specific Antigen (PSA) has been widely used in the diagnosis and management of patients with prostate cancer. It may be elevated in other prostatic diseases and surgical procedures. PSA exists in two forms, a major bound form (cPSA) and a free form (fPSA). Objectives: The objective of the study was to determine the relationship between serum fPSA levels and histologic findings in biopsy specimens of men with prostatic disease. Material and methods: This study includes 91 patients planned for transurethral resection of prostate (TURP). Blood samples were collected before TURP and tested for fPSA. Histology of the tissue samples collected after TURP were studied and the relationship with fPSA analysed using SPSS 11.5. Results: The median values for benign, premalignant and malignant lesions were 1.8ng/ml, 4.5ng/ml and 13.20ng/ml respectively (p<0.001). Most cases of benign prostatic hyperplasia(BPH) without inflammation had fPSA levels <2ng/ ml, while most with active inflammation had levels >5ng/ml. Low grade prostatic intraepithelial neoplasia (LGPIN) saw levels <5ng/ml while high grade intraepithelial neoplasia (HGPIN) and prostate cancer (PCa) had levels > 5ng/mL (p<0.05). For detection of high grade lesions (HGPIN and PCa), the sensitivity and specificity of fPSA level > 5ng/ml was found to be 88.8% and 90.2% respectively. Conclusions: Serum fPSA is elevated marginally in patients with BPH without inflammation. Active inflammation and high grade lesions are associated with fPSA level more than 5 ng/ml. Key words: Benign prostatic hyperplasia, fPSA, prostate cancer, prostatic intraepithelial neoplasia.Publication Diagnosis of multiple myeloma by demonstration of M protein in bone marrow aspirate by agar gel electrophoresis: A case report(Kathmandu University, 2006) Mehta, KD; Khambu, B; Lakhey, M; Lakhey, S; Baral, N; Majhi, SA number of laboratory tests are used to confirm the diagnosis of multiple myeloma, including M protein in the serum. Since M protein in the serum originate from tumour cells in the bone marrow before circulating in the serum, demonstration of M protein in bone marrow aspirate can be added to the batteries of diagnostic parameters. Keywords: Multiple myeloma, Bone marrow aspirate, M band, Agar gel electrophoresisPublication Evaluation of fine needle aspiration cytology of lymph nodes in Kathmandu Medical College, Teaching hospital(Kathmandu University, 2009) Hirachand, S; Lakhey, M; Akhter, J; Thapa, BAbstract Background: Fine Needle Aspiration Cytology (FNAC) is a simple and rapid diagnostic technique. Because of early availability of results, simplicity, minimal trauma and complications, the aspiration cytology is now considered a valuable diagnostic aid and is part and parcel of a pathologist’s repertoire. Objectives: The aim of the study was to evaluate the results of fine needle aspiration cytology (FNAC) of lymph nodes in our institution in comparison to result of histopathology. Materials and methods: The present study on 130 patients of lymphadenopathy was conducted in the Department of Pathology Kathmandu Medical College Teaching hospital, Kathmandu from June 2006 to May 2008 (2 years). Results: In this series of FNAC cervical lymph nodes were 66 (50.76%), and axillary lymph nodes were 20 (15.38%). Male to female ratio of the patients was 1: 0.9. Th age of patients ranged from 3 to 85 years. FNAC diagnosis was found to be as follows : reactive hyperplasia 54( 41.55%), tubercular lymphadenitis 36 (28 %), metastatic carcinoma 16 (12.3%), granulomatous lymphadenitis 12 ( 9.2 % ), lymphoma 8 (6%) and suppurative lymphadenitis 4(3%) . Out of 28 cases of FNAC 26 (92.85%) were consistent with histopathological diagnosis of tubercular lymphadenitis. In metastatic carcinoma to lymph nodes sensitivity and specificity of FNAC were 100% each. Conclusion: FNAC is useful and reliable in diagnosing neoplastic and non- neoplastic lesions of lymph nodes. It helps in planning surgery for malignant cases, where definitive operative intervention can be performed in one session. Key words: FNAC, lymphadenopathy.Publication Fine needle aspiration (FNA) of soft tissue tumours (STT)(Kathmandu Unversity, 2007) Hirachand, S; Lakhey, M; Singha, AK; Devkota, S; Akhter, JObjectives: The cytological findings of 50 ST Ts were evaluated aiming to determine the role of FNA in diagnosis of STTs Methods: Fifty patients with soft tissue tumours underwent FNA in the preoperative investigation during a one year period. The smears were stained with Papanicolaou and May-Graunvald Giemsa stains. Results: Forty-four cases were reported as benign, whereas 2 were malignant. Four cases revealed insufficient material. The malignant STTs were small round cell tumour and malignant spindle cell tumour. Cytological and histological correlation could be achieved in 40 cases. The overall sensitivity and specificity were 25% and 100% respectively with overall accuracy of 80%. Conclusion: A reliable diagnosis of STTs can be made with FNA when supported by other clinical and other diagnostic data. Key words: FNA, soft tissue tumoursPublication Incidence of tuberculosis in enlarged neck nodes, our experience(Kathmandu University, 2009) Maharjan, M; Hirachan, S; Kafle, PK; Bista, M; Shrestha, S; KC, Toran; Lakhey, MAbstract Objectives: To determine the incidence of tuberculous lymphadenitis in enlarged neck nodes. Materials and methods: Continuous prospective study is carried out in the department of otorhinolaryngology head & neck surgery, Kathmandu Medical College, Kathmandu, during two years, from January 2006 to January 2008. The study included a group of 155 patients with cervical lymphadenopathy. Each patient underwent a detail clinical Ear, Nose and Throat (ENT) examination and a battery of investigations which included Fine Needle Aspiration Cytology (FNAC) of the nodes, Montoux’s test, blood Erythrocyte Sedimentation Rate (ESR) and chest X-ray. Those patients with tubercular lymphadenitis were referred to Directly Observed Therapy System (DOTS) clinic for anti-tubercular therapy. Others with reactive lymphadenitis were treated with antibiotic and those with metastatic neck nodes were treated accordingly. Results: Of the 155 cases with enlarged neck nodes, 83 (54%) had tubercular lymphadenitis. Fifty two (33%) cases had reactive lymphadenitis and 17 (11%) cases were diagnosed with metastatic neck nodes. Fine needle aspiration cytology was found to be highly effective in the diagnosis of tubercular lymphadenitis with 94% accuracy. Majority of patients were otherwise healthy adults, aged between 8 – 71 years. No difference was observed between male and female in this study. Posterior triangle (PT) nodes were most commonly affected group of nodes accounting for 35 (42%) cases and preauricular region 1 (1%) case being the least commonly affected site. Fifteen (18%) cases presented with abscess formation. Only 42 (50%) cases had family history of tuberculosis but 8 (9%) patients had previous history of various forms of tuberculosis. Twelve (14%) patients had positive chest X-ray findings suggesting of concurrent pulmonary tuberculosis. All the patients were referred to DOTS clinic and were treated with category (CAT) - III anti tubercular therapy (ATT). Others with concurrent pulmonary tuberculosis were treated with CAT I regime. None of the patients required surgical treatment. Conclusion: There is high incidence of tubercular cervical lymphadenitis in patients with enlarged neck nodes in developing countries like Nepal. Involvement of cervical lymphnodes are the most commonly affected group of nodes. Therefore, it is important that otolaryngologists are aware of tuberculosis in the head and neck region.

The present prospective case control study was undertaken to evaluate the platelet aggregation response in IHD and the effects of aspirin therapy on it. Platelet aggregation was conducted on whole blood by the Chrono- Log whole blood Aggrometer model 540-VS. Various agonists used for platelet aggregation were collagen, ADP, Epinephrine and Thrombin. High platelet aggregation was observed in-patients of IHD as compared to controls by few or all of the reagents used. Platelet aggregation was high in both MI and angina as compared to control cases. However, cases of MI showed higher response than those of angina. Aspirin intake was associated with a decrease in platelet aggregation in patients of IHD. The platelet aggregation response was higher in PRP as compared to whole blood with similar concentration of reagents, however whole blood was equally effective as PRP in detecting hyper- responsive platelets in - patients of IHD.
