An audit of the students\u27 corner of Journal of the Pakistan Medical Association

Objective: To analyze the pattern of the first author\u27s institutional affiliation and the distribution of different article types published in the students\u27 corner of the Journal of Pakistan Medical Association.Methods: This cross-sectional study was carried out in July 2005 and analyzed the students\u27 corner (whenever present) of the Journal of Pakistan Medical Association from January 1998 to June 2005.Results: For the 90 issues of the journal in the stipulated period, 96 articles were published in the students\u27 corner. Original studies 46 (47.9%) were the most commonly published article category followed by personal opinion/review category (43.8%) and case-reports 8 (8.3%). The number of personal opinion/review articles has been steadily decreasing. Students from Aga Khan University contributed 74 (77.1%) articles followed by students from Ziauddin Medical University 10 (10.4%). Almost 95% of the authors were from private medical colleges. Sindh was the location of the first authors institution in 90 (93.8%) cases.CONCLUSION: A major chunk of all articles published in the students\u27 corner of the Journal of Pakistan Medical Association originates from two private medical colleges in Sindh. Efforts must be made to increase student participation across the country. This may be done by asking students to begin scientific writing by submitting personal opinion articles. Further research is needed to assess the status of student research in terms of published output in Pakistan

Primary splenic hydatid cyst: a case report with characteristic imaging appearance

A middle-aged lady presented with pain, tenderness and swelling in the left hypochondrium since one month. She had a history of contact with dogs and grazing animals. Sonography and computed tomography showed the pathognomonic signs of hydatid disease. The patient refused surgical treatment. She was discharged on Albendazole therapy and did not return for a follow up

Tuberculosis of the scapula

Tuberculosis (TB) of the scapula is an extremely rare presentation of osteoarticular tuberculosis. In a tuberculosis endemic setting with a rising burden of acquired immunodeficiency syndrome, this rare presentation may become more frequent. The common presentation is with longstanding Complaints of pain and swelling in the shoulder region, typically in young adults. Classic radiographic features include a well defined radiolucent lesion with minimal sequesteration. The erythrocyte sedimentation rate is usually elevated and initially these patients are frequently mis-diagnosed and thus a high index of clinical suspicion is required. Medical therapy with antituberculous drugs is the standard modality of treatment. This case serves to higlight the salient features of scapular TB

Why Medical Students Are Crucial to the Future of Research in South Asia

One long-term strategy for promoting health research in developing countries is to target medical students early in their careers

A case of non-resolving cough and weight loss.

Sarcoidosis is a chronic granulomatous multi-system disease with a clinical picture often mimicking tuberculosis. We present a case of a patient who presented with a clinical picture akin to both of these granulomatous disorders and was started on anti-tuberculous regimen despite the lack of any solid evidence pointing towards tuberculosis. As a result her clinical condition continued to deteriorate for months until finally a bronchoscopic biopsy established her disease process as sarcoidosis. She was then started on systemic corticosteroid therapy for sarcoidosis and during the ensuing period has shown marked improvement in her clinical picture with near normalization of the biochemical and radiographic parameters of her pathology. This case illustrates the need for vigilant interpretation of the clinical scenario in patients such as these where a misdiagnosis may lead to significant patient distress as well as weighing down on the economic and health resources

Pharmacological basis for medicinal use of Ziziphyus nummularia (Rhamnaceae) leaves in gastrointestinal disorders

Purpose: To explore the pharmacological basis for the folkloric use of Ziziphus nummularia for treating diarrhea and gastrointestinal spasm.Methods: Ziziphus nummularia crude extract (Zn.Cr) was investigated for  antidiarrheal activity (50, 100 and 300 mg/kg) in terms of reduction diarrhea  droppings as well as for antisecretory activity (300 and 1000 mg/kg) in castor-oil induced model in mice. The effect of the extract on potassium chloride (KCl, 80 mM)-induced contractions in isolated rabbit jejunum tissues were was also  examined. Furthermore, the antiulcer properties of the extract was assessed in an ethanol-induced gastrointestinal ulcer model.Results: Zn.Cr (50 – 1000 mg/kg) exhibited protective effect against castor  oil-induced diarrhea (p <0.05, p < 0.01 vs saline group) and intestinal fluid  accumulation (p < 0.001 vs. castor oil group) in mice. In isolated rabbit jejunum model, Zn.Cr concentration-dependently (0.01, 0.1, 0.3, 0.5, 1 and 3 mg/mL) caused relaxation of spontaneous and KCl-induced contractions, similar to  verapamil. Calcium antagonistic effect was indicated, as pretreatment of intestinal tissues with Zn.Cr (0.3, 0.5 and 1.0 mg/mL) produced a rightward shift in Ca2+ concentration-response curves, with suppression of maximum contraction. In ethanol-induced gastric ulceration assay, Zn.Cr (300 and 1000 mg/kg) caused52.5 and 93.6 % inhibition, respectively (p < 0.001 vs. saline group).Conclusion: These results reveal that Ziziphus nummularia possesses anti-diarrheal, anti-secretory, anti-spasmodic and anti-ulcer actions, mediated possibly through voltage-gated Ca2+channel blockade.Keywords: Ziziphus nummularia, Anti-diarrheal, Anti-secretory, Anti-spasmodic, Anti-ulce
