Role of yoga in diabetes.

The science of yoga is an ancient one. It is a rich heritage of our culture. Several older books make a mention of the usefulness of yoga in the treatment of certain diseases and preservation of health in normal individuals. The effect of yogic practices on the management of diabetes has not been investigated well. We carried out well designed studies in normal individuals and those with diabetes to assess the role of yogic practices on glycaemic control, insulin kinetics, body composition exercise tolerance and various co-morbidities like hypertension and dyslipidemia. These studies were both short term and long-term. These studies have confirmed the useful role of yoga in the control of diabetes mellitus. Fasting and postprandial blood glucose levels came down significantly. Good glycaemic status can be maintained for long periods of time. There was a lowering of drug requirement and the incidence of acute complications like infection and ketosis was significantly reduced. There were significant changes in the insulin kinetics and those of counter-regulatory hormones like cortisol. There was a decrease in free fatty acids. There was an increase in lean body mass and decrease in body fat percentage. The number of insulin receptors was also increased. There was an improvement in insulin sensitivity and decline in insulin resistance. All these suggest that yogic practices have a role even in the prevention of diabetes. There is a beneficial effect on the co-morbid conditions like hypertension and dyslipidemia.

OBJECTIVE: The aim of this paper is to report the psychiatric, neuroradiological and linguistic characteristics in a native speaker of Dutch who developed speech symptoms which strongly resemble Foreign Accent Syndrome. BACKGROUND: Foreign Accent Syndrome is a rare speech production disorder in which the speech of a patient is perceived as foreign by speakers of the same speech community. This syndrome is generally related to focal brain damage. Only in few reported cases the Foreign Accent Syndrome is assumed to be of psychogenic and/or psychotic origin. METHOD: In addition to clinical and neuroradiological examinations, an extensive test battery of standardized neuropsychological and neurolinguistic investigations was carried out. Two samples of the patient’s spontaneous speech were analysed and compared to a 500,000-words reference corpus of 160 normal native speakers of Dutch. RESULTS: The patient had a prominent French accent in her pronunciation of Dutch. This accent had persisted over the past eight years and has become progressively stronger. The foreign qualities of her speech did not only relate to pronunciation, but also to the lexicon, syntax and pragmatics. Structural as well as functional neuroimaging did not reveal evidence that could account for the behavioural symptoms. By contrast psychological investigations indicated conversion disorder. CONCLUSIONS: To the best of our knowledge this is the first reported case of a foreign accent like syndrome in conversion disorder.

We investigated three subjects with unexplained sensory loss meeting criteria for conversion disorder using brain fMRI during unilateral and bilateral vibrotactile stimulation. In each subject, stimulation of the affected limb did not produce activation of the contralateral primary somatosensory (S1) region, whereas bilateral limb stimulation did. These findings implicate selective alterations in primary sensorimotor cortex activity in conversion disorder, and may also reconcile the discordant results of previous studies.

Motor training results in performance improvement. It is not yet fully understood the extent to which functional improvement is reflected in changes in brain structure. To investigate the presence and degree of structural brain plasticity induced by long-term bimanual motor activity, we studied 17 right-handed professional typists with average duration of typing practice of 11 years. Using optimized voxel-based morphometry, we correlated the duration of practice and grey matter volume. Regions of interest were applied using 116 previously segmented predefined brain sites. We found a significant positive regression between grey matter volume and duration of practice in brain regions related to the programming of motor tasks. Long-term bimanual training may increase grey matter volume in the brains of professional typists.

Traditional Chinese herbal remedies for asthma and food allergy.

The increasing prevalence of allergic diseases in Westernized countries is a significant health problem. Curative therapies for these diseases are not available. There are also significant concerns regarding the potential side effects from the chronic use of conventional drugs such as corticosteroids, especially in children. Many patients with chronic allergic conditions seek complementary and alternative medicine therapies including traditional Chinese medicines. This trend has begun to attract interest from mainstream health care providers and scientific investigators and has stimulated government agencies in the United States to provide support and guidance for the scientific investigation of complementary and alternative medicine. This effort may lead to improved therapies and better health care/patient outcomes. This review presents an update on the most promising Chinese herbal remedies for asthma and food allergy.
