Abstract

There has been a shift from the teacher oriented teaching learning (TL) methods to learner oriented teaching learning methods. The traditional didactic lecture is frowned upon by many. The internet is looked up to, as a source of unlimited information by both the teaching as well as student fraternity. In this comparative study the knowledge retention immediately after instruction by internet based teacher guided self-study and conventional didactic lecture is assessed. Objectives: To evaluate and assess the knowledge gained by the two teaching methodology. Materials and Methods: Interventional study done with sixty students, an informed consent was taken and divided into two groups of 30 each. Pre test was done. Conventional didactic lecture was used as the method of TL in one group and Internet based teacher guided self-study (IBGSS) was used as the TL method for other. Post test was done after the session. Results: 1. The post test scores after traditional didactic lecture and internet based teacher guided self-study methods where significantly more than pre test, paired t test showed p = 0 and p = 0 respectively; 2. The post test scores of traditional lecture were significantly higher than IBGSS, unpaired t test showed p < 0> The study shows that traditional lecture is better than internet based guided self-study for knowledge assimilation and retention. Keywords: Didactic lecture, Self-study, Medical education.

Abstract

Helicobacter pylori is a bacteria found in many untreated water sources in developing countries. They colonize the luminal surface of gastric epithelium in about 50% of population. Though most infections are asymptomatic, they are the major microorganism causing duodenogastric ulcers, carcinoma of the gastric region and gastric mucosa associated lymphoid tissue (MALT) lymphoma. The serologic study to detect prevalence of Helicobacter pylori was done on healthy blood donors. The cross sectional study was done in a medical college hospital in the state of Kerala; India. The sample was collected from the donated blood. The serum was subjected to serological studies to detect Helicobacter pylori specific IgM and IgG antibodies. The results were noteworthy. A seroprevalence of 29.29% to Helicobacter pylori antibodies was detected in the study group. This is less than similar seroprevalence studies done in different parts of the world. Keywords: Helicobacter pylori, Seroprevalence, Blood donors, Asymptomatic.
