Introduction of active learning method in learning physiology by MBBS students.

CONTEXT: Active learning has received considerable attention over the past several years, often presented or perceived as a radical change from traditional instruction methods. Current research on learning indicates that using a variety of teaching strategies in the classroom increases student participation and learning. AIM AND OBJECTIVES: To introduce active learning methodology, i.e., "jigsaw technique" in undergraduate medical education and assess the student and faculty response to it. SUBJECTS AND METHODS: This study was carried out in the Department of Physiology in a Medical College of North India. A topic was chosen and taught using one of the active learning methods (ALMs), i.e., jigsaw technique. An instrument (questionnaire) was developed in English through an extensive review of literature and was properly validated. The students were asked to give their response on a five-point Likert scale. The feedback was kept anonymous. Faculty also provided their feedback in a separately provided feedback proforma. The data were collected, compiled, and analyzed. RESULTS: Of 150 students of MBBS-first year batch 2014, 142 participated in this study along with 14 faculty members of the Physiology Department. The majority of the students (>90%) did welcome the introduction of ALM and strongly recommended the use of such methods in teaching many more topics in future. 100% faculty members were of the opinion that many more topics shall be taken up using ALMs. CONCLUSION: This study establishes the fact that both the medical students and faculty want a change from the traditional way of passive, teacher-centric learning, to the more active teaching-learning techniques.

Aberrant promoter methylation and reduced expression of p16 gene in esophageal squamous cell carcinoma from Kashmir valley: a high-risk area.

Esophageal squamous cell carcinoma (ESCC) is one of the most prevalent cancer in Jammu and Kashmir region of India and has multi-factorial etiology involving dietary habits, genetic factors, and gene environmental interactions. Inactivation of the p16 gene expression by aberrant promoter methylation plays an important role in the progression of esophageal carcinoma. In the present investigation, we have studied the role of p16 promoter methylation in 69 histopathologically confirmed ESCC tissues and compared it with corresponding normal adjacent tissues for DNA methylation in the CpG island in the p16 promoter region by methylation-specific polymerase chain reaction (MSP) and p16 protein expression by immunoblotting. The results showed loss of p16 expression in 67% (46/69) of tumor tissues compared to only 3% in control tissues (2/69). Promoter methylation was observed in 52% (36/69) of tumor tissues and it gradually increased with the increasing severity of histological grades of the cancer (P = 0.0001). Loss of p16 expression with promoter methylation was observed in 26 of 36 cases (72%). Analysis of patients dietary habits revealed a strong association between promoter methylation and high consumption of hot salted tea (P < 0.05) which is a most favourite drink commonly consumed by Kashmiri people.

Albendazole as an adjuvant to the standard surgical management of hydatid cyst liver.

BACKGROUND: The treatment options for hydatid cyst liver include non-operative and operative methods. Operative methods include conservative and radical procedures. Non-operative methods include chemotherapy and percutaneous treatment of liver hydatidosis. MATERIAL AND METHODS: The study was conducted at Sher-i-Kashmir Institute of Medical Sciences, Soura, Srinagar, Kashmir, India, over a period of two years from March 2001 to February 2003 with further follow-up of 5-6 years. The study included 64 cases in the age group of 15 years to 64 years, comprising 36 males and 28 females. The aim of the study was to know the effect of preoperative and postoperative albendazole therapy on the viability of protoscolices and recurrence rate of hydatid disease of liver. Patients were divided into four group of 16 each. In group A, patients were directly subjected to surgery. In group B, patients were given albendazole for 8 weeks followed by surgery. In group C, patients were given albendazole for 8 weeks preoperatively followed by further postoperative course for 8 weeks. In group D, patients were first taken for surgery followed by postoperative course of albendazole for 8 weeks. RESULTS: Out of those patients who received preoperative albendazole only 9.37% had viable cysts at the time of surgery as compared to 96.87% of patients who did not receive any preoperative albendazole. In those patients who did not receive any albendazole therapy, recurrence rate was 18.75% whereas recurrence was 4.16% in patients who received albendazole therapy. CONCLUSION: We conclude that albendazole is safe and effective adjuvant therapy in the treatment of hydatid liver disease.
