BACKGROUND:Team-based learning (TBL) combines small and large group learning by incorporating multiple small groups in a large group setting. It is a teacher-directed method that encourages student–student interaction. This study compares student learning and teaching satisfaction between conventional lecture and TBL in the subject of pathology.AIMS:The present study is aimed to assess the effectiveness of TBL method of teaching over the conventional lecture.SETTINGS AND DESIGN:The present study was conducted in the Department of Pathology, GMERS Medical College and General Hospital, Gotri, Vadodara, Gujarat. The study population comprised 126 students of second-year MBBS, in their third semester of the academic year 2015–2016.METHODOLOGY:“Hemodynamic disorders” were taught by conventional method and “transfusion medicine” by TBL method. Effectiveness of both the methods was assessed. A posttest multiple choice question was conducted at the end of “hemodynamic disorders.” Assessment of TBL was based on individual score, team score, and each member's contribution to the success of the team. The individual score and overall score were compared with the posttest score on “hemodynamic disorders.” A feedback was taken from the students regarding their experience with TBL.STATISTICAL ANALYSIS USED:Tukey's multiple comparisons test and ANOVA summary were used to find the significance of scores between didactic and TBL methods. Student feedback was taken using “Student Satisfaction Scale” based on Likert scoring method.RESULTS AND CONCLUSIONS:The mean of student scores by didactic, Individual Readiness Assurance Test (score “A”), and overall (score “D”) was 49.8% (standard deviation [SD]-14.8), 65.6% (SD-10.9), and 65.6% (SD-13.8), respectively. The study showed positive educational outcome in terms of knowledge acquisition, participation and engagement, and team performance with TBL.

Background: Trichomonas vaginalis is the most common cause of vaginitis. Diagnosis based on clinical presentation is often inaccurate. Clinical presentation with adjuvant laboratory evidence of trichomoniasis is required for the confirmation of the diagnosis and initiation of therapy. The aim of the present study was to compare the sensitivity and specificity of rapid staining Acridine Orange method for detection of trichomonas vaginalis infection with the routinely employed Papanicolaou staining. Materials and Methods:Vaginal swab smears were prepared from 300 patients attending gynaecology outpatients' clinic of S.S.G. Hospital, Vadodara with complain of abnormal vaginal discharge. The prospective study was conducted over a period of two years (from January' 98 to December' 99). The Papanicolaou and Acridine Orange stained smears were screened for presence of Trichomonas vaginalis infection. Results:In the present study, the incidence of Trichomonas vaginalis infection was 12.3%. Considering Papanicolaou stain as standard, the sensitivity and specificity of Acridine Orange (AO) stain for detection of T. vaginalis was 92.8% and 93.01% respectively. The positive and negative predictive values were 74.2% and 99.2%, while false positive and false negative values are 3% and 0.66% respectively. Conclusion:Trichomonas vaginalis infection is a sexually transmitted disease of the reproductive age group, which needs to be timely diagnosed to prevent its adverse effects. The rapidity, ease and reliability of Acridine Orange stain justify its use in routine laboratory diagnosis of Trichomonas vaginalis infection.
