ABSTRACT
Background: Accurate knowledge of gestational age of the foetus is essential for planning a timely and uneventful outcome. Biparietal diameter, head circumference, abdominal circumference and femur length reliably predict gestational age. The humerus length is not widely used as biometric parameter for determining the GA so the present study was done to estimate foetal gestational age by measuring humerus length between 18 to 36 weeks of normal singleton pregnancies and to compare humerus length with routine parameters.Methods: This was a hospital based descriptive cross-sectional study, 200 women with viable singleton pregnancy, with known LMP, between 18 weeks to 36 weeks of gestation were included. Various foetal measurements such as biparietal diameter, head circumference, abdominal circumference, femur length and humerus length were measured using electronic calipers on ultrasound. Data were statistically analyzed.Results: The mean humerus length at 18 weeks was 25.27±1.16 mm and at 36 weeks of gestation was 57.11±1.58 mm. Simple linear regression analysis shows a strongly significant linear relationship between humerus length and gestational age. Where, gestational age (weeks) Y= 0.5213 x humerus length (X) + 4.905; with high degree of correlation coefficient (R2 =0.9785 and P≤0.0001). When Compared with BPD, HC, AC and FL, humerus length also shows a linear correlation.Conclusions: The measurement of the humerus length can be an important additional parameter for estimating gestational age along with other parameters and can be used to predict the gestational age of fetuses in special circumstances.
ABSTRACT
Background: The present study was designed to assess awareness regarding rational drug therapy and fixed dose combinations (FDC) amongst interns and II MBBS students in a tertiary-care teaching hospital in Maharashtra, India.Methods: This cross-sectional, questionnaire-based study containing MCQ and analytical questions on rational drug therapy, fixed dose combinations and role of Pharmacist in dispensing correct drug to the patients was carried out in both interns (n=80) and II MBBS students (n=100). The completed questionnaires were then collected and analysed statistically for responses.Results: Mean average score obtained by II MBBS students (score - 36.66marks) was significantly better than interns (score- 20marks) which probably may be due to pharmacology teaching they were undergoing. II MBBS students were found to be better informed as compared to the interns (p<0.05) on questions related to rational drug therapy. On the questions related to rationality of FDC in Yes/No type, interns and II MBBS students were found to be equally informed (p>0.05). However, on question related to justification of FDC, interns were found to be better informed as compared to the II MBBS students (p<0.05). On single question pertaining to role of pharmacist, interns were found to be better informed than II MBBS students possibly due to their better understanding of patient-pharmacist relationship.Conclusions: Our study highlights the significance regarding knowledge of rational drug therapy and fixed dose combination (both rational and irrational), both rational and irrational, amongst both interns and II MBBS students while identifying the possible areas of interventions to make them rational clinicians.
