A Study On Impact Of Online Education And Traditional Anatomy Teaching On Student

Background:The emergence of corona pandemic situation in india during april 2020 forced the institutes to send students to their respective hometowns. Faculty had no option but to continue teaching online in such situation. In comparison to other basic medical science subjects, learning anatomy online was felt difficult as the students were unable to understand the three dimensional structures in human body. Rising concerns among students urged to evaluate strength and weakness of ongoing online teaching and learning methods. Aim:To compare the effectiveness of teaching anatomy subject online anatomy theory and practical online teaching.Material And Methods:Study is conducted on 2019-2020 first MBBSbatch 100 student participate in it from my collage. A cross sectional study was conducted among 100 MBBSfirst year medical students from Dr. MK.Shah medical collegeand research centre, Chandkeda,Ahmedabad. Informed consent was obtained from all the students prior to the start of the study. The online classes were conducted due to covid-19 lockdown in our institution from April 2020 as per the guidelines from government. The study was conducted by taking feedback from the students in the form of pre-formed questionnaire regarding the online classes in Google forms for 1styear MBBSstudents. Questionnaire consisted of information related to difficulties encountered by students during online class andunderstanding of subject during online class.Result:A 60% studentsagree thatlectures areeffective to understand in online teaching.76% student use mobile for attendonline lecture. 50% student disagree that dissection in anatomy can effective by online teaching.Online lecture on zoom is accepted method for online teaching by 78% of student.69% students attend 30 minute online class out 60 min class.90% student recommends that for dissection teaching in dissection hall is more effective.Again 75%student offline class for demonstration class is effective.61% student facing internet issue during online class.Conclusion:Students preferred classroom teaching over online teaching for anatomy subject. Between the platforms used in online teaching, google meet has an edge over google classroom in terms of learning.

A Study On The Morphological Variations Of The Human Liver And Its Clinical Implications In Gujarat Region

Background:liver is a soft, friable and largest gland in the body, occupying the upper part of the abdominal cavity just beneath the right diaphragm. The greater part of it is situated under cover of the ribs, extending to the left to reach the left diaphragm. Objective: to determine gross anatomical variations of liver and their clinical and surgical implications. To study variations in lobes, fissures and accessory lobes were observed. Material And Methods:a total of 50 formalin-fixed adult human livers, irrespective of the sex, were studied over a period of three years from Dr M K shah medical college. These livers were specifically observed for any variant or anomalous surface morphology. Result:out of 50 specimens, 16 were considered normal without any ac-accessory fissures, lobes, or presence of a pones hepatis. 34 livers had one or more morphological variations.14 liver has accessory fissure, 10 liver are present with riedel’s lobe present in liver, 10 liver are present with pons hepatic. Conclusion:liver being the largest abdominal organ, the knowledge of its normal and variant morphology is essential for the clinicians. In general, accessory hepatic fissures/sulci are potential sources of diagnostic errors during imaging. On ultrasound or computerized tomography, any collection of fluid in these fissures may be mistaken for a liver cyst, intrahepatic hematoma, or liver abscess, which would require further radiologic workup.

Origin of left accessory hepatic artery from the left gastric artery.

In recent years there has been an increase in number of transplantation surgeries, especially live donor liver transplantation in the western countries. So, anatomical variations of Hepatobiliary vessels gained special attention from anatomists, Gastroenterological surgeons and Interventional radiologists. We report a case of the accessory hepatic artery that arise from the left gastric artery, entered the liver at an independent site from the portahepatis to supply the left lobe of the liver. Transplantation of such livers with multi vascular pedicles may pose a challenge during anastomosis of these accessory hepatic arteries of the donor liver to the nearby arteries of the recipient.

Impacts of mining activities on water and soil.

Seven coal mines are situated in Wardha River Valley. These mines are located at Wani (Dist. Yavatmal of Maharashtra). Out of these, 5 open cast coal mines are run by Western Coal Field Ltd. India. The present study has been undertaken to assess the impacts of mining activities in the adjacent areas. Total 25 samples of water and 19 samples of soil from Nilapur, Bramhani, Kolera, Gowari, Pimpari and Aheri were analyzed for pH, TDS, hardness, alkalinity, fluoride, chloride, nitrite, nitrate, phosphate, sulfate, cadmium, lead, zinc, copper, nickel, arsenic, manganese, sodium and potassium, and the results were compared with the limits of Indian Standards: 10500.

Ciprofloxacin in typhoid fever.

The study covers 78 children with typhoid fever who were hospitalized in April & May 1990. Serious complications were present in 32% (toxemia 22%, ileus 25% and myocarditis 8%). Blood cultures were positive in 30 of 49 tested. Others were diagnosed by positive Widal test. In vitro cultures of S. typhi were resistant to chloramphenicol (90%), ampicillin (93%) and co-trimoxazole (97%). However all were highly sensitive to ciprofloxacin and moderately sensitive to cephalexin and gentamycin. Ciprofloxacin alone or in combination was given in 73 of the 78 children and found to be remarkably effective in controlling the disease and preventing relapse. No serious side effects were noted. The cohort is being followed up for possible long term adverse effects.

Prophylactic use of mexiletine in the elderly with acute myocardial infarction.

A double blind randomised study comparing the effects of oral mexiletine and placebo given to elderly patients (65 years and older) immediately following hospital admission with suspected myocardial infarction (MI) is described. The study comprised one hundred and fifty-four patients of which 74 had confirmed myocardial infarction according to the diagnostic criteria of the study. Eighty patients without definite evidence of myocardial infarction were subsequently excluded from the study. Thirty-three patients (44.5%) with confirmed MI treated with mexiletine, compared with 41 (51%) in the placebo group showed no significant difference in mortality at 48 hours and 14 days. The mexiletine treated group showed a significant reduction (p less than 0.05) in certain forms of ventricular dysrhythmias. Six of these patients (18%) taking mexiletine had the drug withdrawn because of possible adverse drug reactions compared with two (4.8%) of the placebo group. None of the patients withdrawn because of possible adverse drug reactions had any long term side effect. Mild confusion observed in one patient was reversed after withdrawal of therapy. Results of this study indicate the safety of mexiletine as an anti-arrhythmic drug and its efficacy in suppression of certain ventricular dysrhythmias in the elderly with acute myocardial infarction. The overall mortality rate in both groups (mexiletine and placebo) remained unchanged.
