<p><b>Aims: </b>To determine the correlation between our questionnaire scores and two standard Parkinson's disease (PD) disability scores [Unified Parkinsons' Disease Rating Scale (UPDRS) and Hoehn and Yahr (H and Y)], and to study the correlation between the various subgroups of our dysphagia screening questionnaire.</p>

<p><b>Settings and Design: </b>This study was conducted at a movement disorder clinic in a tertiary care hospital in Kochi, Kerala. This was a cross-sectional observational study.</p>

<p><b>Materials and Methods: </b>A questionnaire was developed comprising 11 items, keeping in mind the most relevant swallowing issues in PD patients. The questions were subdivided into four groups representing the different stages of swallowing. Reliability and validity studies were conducted for the questionnaire. Corresponding UPDRS and H and Y scores were documented on the same day.</p>

<p><b>Statistical Analysis Used: </b>Mean and standard deviation (SD) values of the scores in each group and the correlation between scores (Pearson correlation coefficient) were done.</p>

<p><b>Results: </b>Responses were obtained from 106 PD patients (67 males, 39 females), with a mean age of 66.9 years (SD, 8.62). Our questionnaire score showed a high coefficient of variation (145%) compared to the UPDRS and H and Y scores. There was also moderate correlation between our questionnaire score and the two standard scores with a significant P value. Finally, the highest mean scores were for questions from group A and the least for questions from group D.</p>

<p><b>Conclusions: </b>The association between worsening motor symptoms and swallowing difficulties has been documented in this study. The oral stage of swallowing remains the most affected in PD, which can be recognized early using our questionnaire.</p>

Anu Sasidharan, John, A., and Prof. K. R. Sundaram, “Comparison of knowledge, attitude and practice FF self-learning among different levels of faculty members”, Journal of South India Medicolegal Association, vol. 9, pp. 18-25, 2017.[Abstract]

The teaching methodologies in medical colleges can be tilted towards teacher centric or learner centric kind of approach. Recently Medical Council of India has been mandating revised faculty training programmes and one of the objectives of such training programmes is to promote a learner-centred approach. Self-Learning is the vital component of a learner-centred approach in medical education. Through self-learning the learners assume responsibility for their learning thereby facilitating adult learning. However till date, there is no published literature on the existing knowledge, attitude and practice of self-learning among faculty members of a medical college. Unless the existing scenario is clear, it is not possible to decide on the emphasis of self-learning in the revised faculty training programmes across the country. Moreover unless the faculty members are trained adequately, it is near to impossible to promote self-learning in the learners. This pilot research work was chosen as a beginning to determine this gap of knowledge of existing scenario amongst the faculty members in medical colleges. 30 junior level and 30 senior level faculty members voluntarily participated in this study that lasted six months. The results have shown that the attitude and practice of self-learning in faculty members, especially juniors were disappointing and it is high time for research works relating to medical education to be taken up involving faculty members in order to understand the pitfalls in the existing system. © 2017 South India Medico-Legal Association.

Prof. K. R. Sundaram, Dwivedi, S. N., and Sreenivas, V., Medical Statistics : Principles and Practice, 2/e. New York & New Delhi : Wolters Kluwer, 2015.[Abstract]

Medical treatment is nowadays driven by evidence. To derive reliable evidence, well planned and carefully carried out studies with appropriate analyses and interpretations are necessary. In this regard, biostatistical methods are the recognized tools. Hence, training of medical and public health student and researchers invariably includes biostatistical methods. The second edition of this book is aimed at providing updated and accurate information on relevant topics. It will serve as a textbook of biostatistics for both graduate and postgraduate medical courses, public health and epidemiology courses and other allied health science courses such as biostatistics, pharmacology, health administration, nursing, and clinical research.
