RESUMO
BACKGROUND: In the past, textbook or printed material was the only source of information for medical students or post-graduate students. After the introduction of internet, knowledge can be accessed easily which is updated with various aids such as animation, videos which improve the learning efficiency. This study was conducted to compare the learning efficiency between textbook-based seminar to that of internet-based seminar in postgraduate students of the department of dermatology. MATERIALS AND METHODS: It was a non-randamized controlled study. The postgraduate students in the department of dermatology, Jawaharlal Nehru Medical college, DMIMS(DU),Sawangi (Meghe), Wardha, Maharashtra, India were divided into two equal groups by simple randomization method by flipping the coin. Totally 20 seminar topics were divided into two groups (A and B) consisting of 10 seminars in each group. Postgraduate students assigned in group A were asked to prepare seminar solely from textbooks while in group B, students were asked to prepare seminar by referring internet. Feedback form which consists of 7 points, i.e. appearance, completeness of preparation, clarity of presentation, appropriate use of audio visual aids, understanding of subject, ability to answer questions, and overall performance were filled up from faculties and postgraduate students after completion of each seminar. Pretest and post-test were filled up from postgraduate students before and after each seminar respectively. Learning gain was calculated by comparing the scores of pretest and posttest. Paired t-test was used to compare results in the group and unpaired t-test was used to compare results between the two groups. RESULTS: Faculties' feedback on overall performance was higher (4.59 ± 0.15) in web-based seminars as compared to in textbook-based seminars (3.85 ± 0.1) with significant P = 0.008. Furthermore, postgraduate students' feedback showed statistical significant value of 0.02 in web-based seminars (4.65 ± 0.06) compared to textbook-based seminars (3.2 ± 0.06). Learning gain was significantly higher in web-based seminar compared to textbook-based seminar with P = 0.02. CONCLUSION: It can be concluded that web-based learning can improve the learning efficiency in postgraduate medical students.
RESUMO
Stewart-Bluefarb acroangiodermatitis is the occurrence of pseudo-kaposiform changes with an underlying arterio-venous malformation. Parkes-Weber syndrome is a triad of arterio-venous malformation with varicose veins with bony and soft-tissue hypertrophy involving the extremity. A 13 year-old-female presented with ulcerated growth with bleeding episodes on right leg since past four years. A reddish discoloration over right leg was noticed at four years of age which remained unchanged until nine years of age, after which it showed rapid increase in size along with disproportionate increase in length and girth of right lower limb. Examination revealed hyperpigmented soft verrucous plaque over the right lower one-third of leg, along with presence of ulcers and dilated tortuous veins in the right lower leg with thrill and bruit over the right popliteal and inguinal region. A differential diagnosis of verrucous hemangioma and arterio-venous malformation with pseudo-kaposiform change was considered. Skin biopsy showed multiple fenestrated capillaries with perivascular lymphocyte infiltrate suggestive of capillary malformations. X-ray showed osteolytic defect in right tibia. Duplex ultrasound and magnetic resonance imaging of right leg showed multiple fast flowing small and medium sized arterio-venous malformations of small to moderate size. Thus, on the basis of clinical and radiological features, we made a diagnosis of Stewart-Bluefarb type of acroangiodermatitis with Parkes-Weber syndrome. She was managed conservatively with compression stockings.
