Future specialization interests among medical students in southern India.

Background. A consideration of the future specialization interests of undergraduate medical students might help to understand the needs of higher medical education and future manpower availability for healthcare. Methods. A cross-sectional study was conducted among 373 undergraduate students of a medical college in southern India using a self-administered questionnaire. Results. Of the 373 students, 188 (50.4%) were men. Almost all of them (370 [99.2%]) wanted to pursue postgraduation. Of these, 267 (72.4%) wanted to pursue postgraduation in India. Overall, the first choice subject was surgery (120 [32.2%]) followed by internal medicine (85 [22.8%]) and paediatrics (43 [11.5%]). The third preference for men and women differed, with men choosing orthopaedics and women choosing obstetrics and gynaecology. The factors that influenced the choice of specialization were interest in the speciality (Likert scale score 4.7), job satisfaction (4.6), employment opportunities (4.0), job security (4) and high income potential (3.9). Conclusion. It was evident from the proportion of students desiring to do postgraduation and their choice of specialties that most of them will end up working at hospitals instead of at primary healthcare centres. The deficiencies of certain specialists such as ophthalmologists are likely to persist. This is a cause for concern as the majority of our population lives in rural areas and there is already a maldistribution of doctors.

A comparison of responses to alcohol expectancy questionnaire (CEOA) of Indian and Malaysian medical students.

Alcohol addiction is a social problem faced by every country worldwide. Young people are more at risk of this menace. In spite of a clear knowledge and message about the effects of alcohol on individual health and social fabric, it is hard to curb the overuse of this beverage. In the present study, we compared the outcome of a survey using Comprehensive effects of Alcohol (CEOA) in two private Medical institutions in two Asian countries, viz. KMC, Mangalore, India (n=180) and AIMST, Kedah, Malaysia (n=170). The study included both males and female students. The result suggested that the negative reinforcement responses were rated higher in both the study groups. But those who have tasted alcohol before had a higher rating that alcohol may cause positive reinforcement. Both groups of respondents showed similar trend suggesting that the alcohol expectancies are similar in Indian students and Malaysian students. From the results we could conclude that the responses of the two sample groups were comparable to each other. While the male respondents were inclined show higher affinity towards acceptance of alcohol females are very much less so. However, the respondents of both groups appeared to be well aware of the negative aspects of alcohol. Importantly previous exposure to alcohol intake dramatically changed the perception and showed increased inclination towards alcoholism. This study thus provides an important clue to the clinician, counselors and parents regarding the importance of guiding the young people about the alcoholism.

Determinants of low birth weight: A case control study in a district hospital in Karnataka.

A Case-control study was conducted in District Lady Goschen hospital, Dakshina Kannada district, Southern Karnataka. Subjects were mothers who underwent normal delivery and their neonates. A total of 150 cases and 300 controls were selected. Significant risk factors identified in univariate analysis included pre pregnancy maternal weight (<45 kgs)(OR=6.77), anaemia in pregnancy (Hb<11gm%) (OR=3.11), age less than 20 years (OR=2.96) and maternal height (<145 cms) (OR=2.79). Multiple logistic regression analysis revealed that pre pregnancy maternal weight (<45 kgs)(OR=7.02), anemia in pregnancy (OR=4.37) and maternal age less than 20 years (OR=3.96) were the significant risk factors of low birth weight of term babies. The strategy needs to focus attention on nutrition education to facilitate better weight gain during adolescent period. Discouraging teenage pregnancy is also essential in order to reduce the burden of LBW babies.

Prevalence of goitre among school children in Belgaum District.

Objective. A school survey was conducted to estimate the prevalence of goitre among schoolchildren in Belgaum district. Methods. A cross-sectional study was conducted in primary, middle and high schools of villages selected. All the children of the selected schools were examined for the presence of goitre and the salt samples obtained from their homes were tested for iodine content. Results. Overall prevalence of goitre was 16.7%. Prevalence of palpable goitre was 16.4 % and visible goitre was very low (0.3%). Higher prevalence was found among females (21.1%) when compared to that of male children (12.8 %). Prevalence of goitre increased significantly with advancement of age until 16-yr. 72.1 % children were consuming rock salt and only 27.9 % were consuming powdered salt at their homes. Estimation of Iodine content in the salt samples showed that 68.7 % of the sample had inadequate iodine content. Prevalence of goitre was significantly high among children who consumed rock salt (16.2%) as compared to those who used powdered salt (11%). Conclusion. Strict implementation of salt codization and marketing in rural area is desired. Also health education programme be showed.

Alcohol expectancy responses from first year medical students: Are they prone to alcoholism?

CONTEXT: Modern life style and affluence lead to changes in people's outlook on various habits, including alcohol intake. Some of them will fall prey to the addictive nature of the drink. AIMS: Present study was done to evaluate the responses to comprehensive alcohol expectancy questionnaire (comprehensive effects of alcohol - CEOA) in order to test the tendency towards alcohol intake among the First Year Medical (MBBS) students of our college - that is, to assess the positive or negative reinforcement they would expect if they consumed alcohol. SETTINGS AND DESIGN: The study was done by giving a set of questionnaires to be answered by the students. MATERIALS AND METHODS: Questionnaires of CEOA had 38 responses, in which both negative and positive feelings were represented. All questions were again grouped into four groups of positive and three groups of negative responses. Each question was rated to what degree they agreed, by 4-point Likert-type scale (1 = disagree, 2 = slightly disagree, 3 = slightly agree, 4 = agree). The positive and negative responses were analyzed to group them into agreeing or disagreeing type. STATISTICAL ANALYSIS USED: Analysis of responses by Student 't' test and 2-way ANOVA was done to analyze the results. 'P' RESULTS: Results showed that negative expectancies outweighed positives significantly (2.8017 +/- 0.58554 vs. 2.3055 +/- 0.67604, t = 7.526; P< 0.001.). Females rated the negatives more firmly (P< 0.001). However, there was no statistically significant difference with respect to different religious beliefs, places of origin or incomes of the respondents. An experience of alcohol had a significant effect on the responses where they had stronger positive expectancy, which is an important point revealed in this study. CONCLUSIONS: In this study, we have observed a general acceptance that alcohol could provide positive reinforcement, especially among those who have had a prior experience of intake of alcohol. Thus, this study throws light on whether there is likelihood of youngsters falling into addiction in the later part of their life; hence it can act as a useful predictor for parents, health professionals, social counselors and the society as a whole so that they can take preventive measures against alcohol addiction.

Safety and radiosensitizing efficacy of sanazole (AK 2123) in oropharyngeal cancers: randomized controlled double blind clinical trial.

Oropharynx is an important site of cancer in India. Global comparison indicates higher incidences in India. Radiotherapy remains an important treatment modality. Efforts to improve loco-regional treatment and prolong survival are areas of focus. Radiosensitizers in hypoxic tumors have shown promise. AIM: To study the safety and radiosensitizing efficacy of sanazole in oropharyngeal squamous cell carcinoma (stage T2-4, N0-3, M0) as phase-II double blind controlled trial in patients treated with conventional radiotherapy. SETTINGS AND DESIGN: Single institutional, randomized, double-blind, placebo-controlled trial. MATERIALS AND METHODS: Group 1 (control; n = 23) received normal saline infusion, group 2 (test; n = 23) received sanazole biweekly 1.25 g intravenous infusion 15 minutes before radiotherapy. Surrogate end points of efficacy were tumor and nodal size; safety parameters were mucositis, salivary and skin reactions, dysphagia, vomiting, dysgeusia and neurological deficit. Investigators blinded to the trial evaluated patients, weekly during treatment for six weeks and thereafter monthly for three months. STATISTICAL METHODS: Non-parametric, Friedman's, Chi square, Mann-Whitney U tests. RESULTS: In the test, 15 (65%) patients had complete response, five (22%) partial/no response, two (9%) died, one (4%) lost to follow up. In the control, five (22%) patients had complete response, 16 (70%) partial/no response, one (4%) died, one (4%) lost to follow up. Short-term loco-regional response was better in the test (DF = 3, 95% Confidence Interval 0.418, 0.452, P = 0.0048). In the test group significant vomiting and one case of grade 3 neurological deficit was observed. CONCLUSION: The study validates the usefulness of sanazole for initial loco-regional control in oropharyngeal cancers.

Immunohistochemical evaluation of expression of cytokeratin 19 in different histological grades of leukoplakia and oral squamous cell carcinoma.

Recent progress in understanding the biology of keratins together with the development of monoclonal antibodies to individual keratin proteins provide the foundation for studying the keratin expression in normal and pathological oral epithelia. Cytokeratin (CK) alterations have been reported in carcinomas and these have been associated with specific aspects of tumour behaviour. Immunohisto-chemistry with monospecific CK19 antibody was used to study the expression pattern in normal mucosa, dysplasias, and oral squamous cell carcinomas (OSCC). In non-keratinzed normal mucosa, CK19 was detected in the basal cell layer, while in dysplasias (diagnosed in H and E stained sections, mild-severe) stained strongly for CK 19 in the basal and supra basal cell layers indicating layer specificity for CK 19 expression. In OSCC, in the number of CK19 labelled cells increased from well to poorly differentiated tumour. Thus the results of the present study indicate an alteration in synthesis of keratin proteins when exposed to carcinogens.

Occupational dermatoses in beedi rollers.

A total of 91 beedi workers were analyzed for the pattern of cutaneous lesions. Period of rolling beedi ranged from 2 months to 40 years. Dermatological findings included; callosities seen in 51 (56.04%) of workers on fingers and feet, nail changes in 22 (24.18%) like pigmentation, paronychia, dystrophy which were more prominent on the right index finger, fungal infections in 15 and eczemas in 29. Callosities and localised nail changes can be considered to be occupational marks in beedi rollers correlated to use of scissors for cutting leaves and use of gum and artificial metallic nails for rolling beedis.

Topical phenytoin in diabetic ulcers: a double blind controlled trial.

Data of 57 patients who completed the trial and 13 who did not, were analysed. With phenytoin, there was a marginal: increase in the reduction of mean ulcer area and acceleration of effect 3rd on 4th week. With control: the number completing the trial was larger: response to treatment was better in grade II ulcers, Table IV. This study has the hall marks of a real clinical trial, has raised the possibility of wound healing properties of phenytoin and confirms the results of others.

Evaluation of immunoglobulin G synthesizing plasma cells in periapical granuloma and cyst.

Immunoglobulin synthesizing plasma cells for IgG were quantitated in 20 periapical granulomas and 20 periapical cysts, using unlabelled antibody peroxidase-antiperoxidase complex method. Result showed that immunoglobulin G producing plasma cells were predominant in periapical cyst as compared with periapical granuloma. A statistical significant relation was observed between these two lesions.

Exponential model for weight using 'RJ index'.

We screened a sample of 204 children between the age of 3 months to 5 years and 3 months were during a general health survey conducted by the Department of Community Medicine, Kasturba Medical College, Mangalore from March 1992 to December 1993 at Kumpala village under PHC Ullal about 10 kms from Mangalore City. We developed a new index RJ as RJ = Mid upper Arm Circumference x (Height)2 x 10(-4) and tested the correlation of RJ index and weight for age. We found the correlation coefficient (r = 0.8) to be very significant (P < 0.001). Thus we propose the model as Weight = A x exp (RJ x B). We found that the available data fit in this model. We hope that this study will be a new step in looking at arm circumference as a tool in estimating weight of pre-school children.

Vaccination coverage assessment survey in Mangalore (urban), Karnataka.

A vaccination coverage assessment survey regarding the U.I.P. vaccines, among 210 children aged 12-23 months and 210 mothers of infants was undertaken in Mangalore (urban) in February--March 1991, with the specific objectives of assessing the extent of achievement here of the U.I.P. objectives for the vaccine coverages, and identifying the reasons for immunization failures as well the sources of immunization. The sample population was selected by the standard WHO. 30 cluster sampling technique. A door-to-door survey was undertaken in the study population and the data was elicited by interview of mothers (and confirmed from vaccination cards or registers if available). The investigator inquired about DPT 3, OPV 3, one dose each of BCG and Measles vaccine and TT2/B for mothers. The coverages for the individual vaccines were observed as follows (and indicated in parentheses) DPT 3 (91.9%) OPV 3 (92.3%), BCG (91%), Measles vaccine (69.5%) and TT2/B for mothers (94.7%). The drop-out rates from first to third dose of both DPT and OPV were observed to be 2.5%. The major reasons for immunization failures were reported to be unawareness of need, illness of child, and fear of side reaction. Hospitals were availed of more than private sources for immunization services. The universal immunization coverage in Mangalore (urban) was found to be highly satisfactory.
