Aim: This study aims to investigate any modification of serological FSCN1 in prostate cancer patients compared with patients without neoplasia. Material & methods: Clinical data and blood specimens from patients with and without prostate cancer were obtained. A quantitative sandwich ELISA method was used to determine serological values of FSCN1. Results: Although serum values of FSCN1 were dissimilar in the two cohorts of patients (6.90 vs 7.33 ng/ml), the difference was not statistically significant (p = 0.20). Serum values of FSCN1 stratified for Gleason score groups were not significantly distinguishable (p = 0.65). A negative correlation (rho = -0.331; p = 0.009) was reported between FSCN1 and age. Conclusion: Further studies are required to evaluate a possible diagnostic role of FSCN1 in prostate cancer.

PURPOSE: To investigate the causes of the raised risk of lung cancer in patients who have had Hodgkin’s disease, and in particular the relationship to treatment. PATIENTS AND METHODS: A nested case-control study was conducted within a cohort of 5,519 patients with Hodgkin’s disease treated in Britain during 1963 through 1993. For 88 cases of lung cancer and 176 matched control subjects, information on treatment and other risk factors was extracted from hospital case-notes, and odds ratios for lung cancer in relation to these factors were calculated. RESULTS: Risk of lung cancer was borderline significantly greater in patients treated with mechlorethamine, vincristine, procarbazine, and prednisone (MOPP) chemotherapy than those who did not receive this treatment (relative risk [RR] = 1.66; 95% confidence interval [CI], 0.99 to 2.82), and increased with number of cycles of MOPP (P = .07). Exclusion of lung cancers for which histologic confirmation was not available strengthened these associations (RR = 2.41; 95% CI, 1.33 to 4.51; P = .004 for any MOPP and P = .007 for trend with number of cycles of MOPP). Risks were not raised, however, after chlorambucil, vinblastine, procarbazine, and prednisone treatment. There was evidence that the raised risk of lung cancer occurring in relation to radiotherapy was restricted to histologies other than adenocarcinoma. CONCLUSION: The results suggest that MOPP chemotherapy may lead to elevated risk of lung cancer, at least in certain subgroups of patients. The role of chemotherapy in the etiology of lung cancer after Hodgkin’s disease deserves further investigation.

Background: In the developing countries where TB is endemic; an ideal test for tuberculous meningitis should be economic, minimally invasive, of high accuracy and quick to perform.In many countries, also in India, several studies were conducted to establish the ADA activity as a sensitive and specific test of tuberculous meningitis.So it is very much needed to evaluate the diagnostic role of CSF ADA in tuberculous meningitis in Bangladesh. Aim: This study aimed to find out CSF ADA as a sensitive and specific test for early diagnosis of tuberculous meningitis. Methods: This case control study was carried out in the Department of Neurology, SSMC and Mitford Hospital, Dhaka from June 2011 to July 2012, to evaluate ADA activity in CSF for diagnosis of tuberculous meninigitis. Results: In the present study, sixty meningitis patients were enrolled. Of which, 30(50%) were tuberculous meningitis (TBM) taken as cases and rest 30(50%) were non-tuberculous meningitis (NTBM) taken as control.The CSF ADA activity from TBM patients was compared with CSF ADA from non-TBM infectious meningitis patients. The mean CSF ADA activity was found to be significantly higher in CSF of TBM patients, 14.01 ± 12.4 (1.0–65.2), mean ± SD with range, than in the CSF from non-TBM infectious meningitis, 7.2 ± 8.2 (1.8–49.1) P = 0.01.A cut-off value of >7.6 U/L for the TBM patients was calculated from the mean ±SD of the non-TBM patients.The ADA sensitivity is 81.82%,specificity 65.31%,accuracy 68.33%, PPV 34.62%,NPV 94.12%, positive likelyhood ratio 2.3 and lastly negative likelyhood ratio 0.2 for infectious TBM when this cut-off value was used.ROC curve shows area under curve of .736 suggests a moderate accuracy of the test in detection of tuberculous meningitis. Conclusion: This study demonstrated that ADA activity in the CSF of TBM patients, using a cut off value 7.6 U/L, can be useful for the early differential diagnosis of TBM. This test can be performed in any pathology laboratory where more sophisticated methods are not available. Bangladesh Journal of Neuroscience 2013; Vol. 29 (2) : 79-87
