Psychosis and Seizure Disorder: Challenges in Diagnosis and Treatment

Bipolar disorder is associated with high mortality, and people with this disorder on average may die 10–20 years earlier than the general population. This excess and premature mortality continues to occur despite a large and expanding selection of treatment options dating back to lithium and now including anticonvulsants, antipsychotics, and evidence-based psychotherapies. This review summarizes recent findings on mortality in bipolar disorder, with an emphasis on the role of suicide (accounting for about 15 % of deaths in this population) and cardiovascular disease (accounting for about 35–40 % of deaths). Recent care models and treatments incorporating active outreach, integrated mental and physical health care, and an emphasis on patient self-management have shown promise in reducing excess mortality in this population.     

Anthoceros subtilis Steph: A Rare Disjunct Species,New to North East India from Brahmaputra Valley

A rare bryophyte, Anthoceros subtilis Steph., earlier reported in India only from Western Ghats, (Karnataka and Maharashtra), Gujarat, Rajasthan and elsewhere in world from China, Thailand and Vietnam, has been discovered from southern Brahmaputra flood plains of Assam.     

Comparative analysis of different methods used for molecular characterization of Burkholderia cepacia complex isolated from noncystic fibrosis conditions

PurposeBurkholderia is a Gram-negative opportunistic bacterium capable of causing severe nosocomial infections. The aim of this study was to characterize Burkholderia cepacia complex and to compare different molecular methods used in its characterization.MethodsIn this study, 45 isolates of Burkholderia cepacia complex (Bcc) isolated from clinical cases were subjected to RAPD (Random amplified polymorphic DNA), recA-RFLP (Restriction fragment length polymorphism), 16SrDNA-RFLP, whole-cell protein analysis, recA DNA sequencing and biofilm assay.ResultsOf the 45 isolates tested, 97.7% were sensitive to ceftazidime, 82.2% were sensitive to Cotrimoxazole, 73.3% were sensitive to meropenem, 55.5% were sensitive to minocycline and 42.2% were sensitive to levofloxacin. Majority of the isolates harbored all the tested virulence genes except bpeA and cblA. The RAPD generated 11 groups (R1-R11), recA-RFLP 10 groups (A1-A10), 16SrRNA-RFLP 5 groups (S1–S5) and SDS-PAGE (Sodium Dodecyl Sulphate-Polyacrylamide gel electrophoresis) whole cell protein analysis revealed 12 groups (C1–C12). recA sequencing revealed that most of the isolates belonging to the genomovar III Burkholderia cenocepacia. Though all the methods are found to be efficient in differentiating Burkholderia spp., recA-RFLP was highly discriminatory at 96% similarity value. The study also identified a new strain Burkholderia pseudomultivorans for the first time in the country. Further, recA sequencing could identify the strains to species level. Majority of the multidrug-resistant strains also showed moderate to strong biofilm-forming ability, which further contributes to the virulence characteristics of the pathogens.ConclusionsThe study highlights the importance of combination of molecular methods to characterize Burkholderia cepacia complex. Molecular typing of these human pathogens yields important information for the clinicians in order to initiate the most appropriate therapy in the case of severe infections and to implement preventive measures for the effective control of transmission of Burkholderia spp.     

Pellagra in a child–A rare entity

This case has been presented as pellagra, which is very rare in children. Pellagra is due dietary deficiency of niacin. Usually seen in alcoholics, malabsorption syndromes occur very rarely in children. A 11-y-old girl presented with well-defined, hyperpigmented, hyperkeratotic, symmetrical, thick scaly plaques surrounded by erythema on the dorsum of the hands, arms, feet, legs up to knees, and along the sides of the neck. The child was given 100 mg of Nicotinamide. Skin lesions resolved rapidly with the treatment and the child improved.
