Management of geriatric mania complicated by hyponatremia and psychogenic adipsic hypernatremia

A 70-year-old male presented with first episode mania and hyponatremia, which were later corrected with an infusion of hypertonic saline. His clinical condition deteriorated because of adipsic hypernatremia associated with hypokalemic periodic paralysis. Hypernatremia correction and potassium supplementation were started but could not be achieved because of manic symptoms as the patient's oral intake was poor. He was restarted on sodium valproate and olanzapine. Over the next few days, the patient's manic symptoms improved significantly and oral intake improved, which eventually led to correction of hypernatremia. Clinicians should evaluate the existence of electrolyte imbalance while dealing with a case of geriatric mania

Population differences in brain morphology: Need for population specific brain template

Brain templates provide a standard anatomical platform for population based morphometric assessments. Typically, standard brain templates for such assessments are created using Caucasian brains, which may not be ideal to analyze brains from other ethnicities. To effectively demonstrate this, we compared brain morphometric differences between T1 weighted structural MRI images of 27 healthy Indian and Caucasian subjects of similar age and same sex ratio. Furthermore, a population specific brain template was created from MRI images of healthy Indian subjects and compared with standard Montreal Neurological Institute (MNI-152) template. We also examined the accuracy of registration of by acquiring a different T1 weighted MRI data set and registering them to newly created Indian template and MNI-152 template. The statistical analysis indicates significant difference in global brain measures and regional brain structures of Indian and Caucasian subjects. Specifically, the global brain measurements of the Indian brain template were smaller than that of the MNI template. Also, Indian brain images were better realigned to the newly created template than to the MNI-152 template. The notable variations in Indian and Caucasian brains convey the need to build a population specific Indian brain template and atlas

The 3rd Schizophrenia International Research Society Conference, 14-18 April 2012, Florence, Italy: Summaries of oral sessions

The 3rd Schizophrenia International Research Society Conference was held in Florence, Italy, April 14-18, 2012 and this year had as its emphasis, The Globalization of Research . Student travel awardees served as rapporteurs for each oral session and focused their summaries on the most significant findings that emerged and the discussions that followed. The following report is a composite of these summaries. We hope that it will provide an overview for those who were present, but could not participate in all sessions, and those who did not have the opportunity to attend, but who would be interested in an update on current investigations ongoing in the field of schizophrenia research. © 2012 Elsevier B.V
