This review presents a comprehensive and updated overview of bigerminal choristomas (hairy polyps) of naso-oropharynx/oral cavity, and discusses the controversies related to nosology and origin from a clinico-embryologic perspective. English-language texts of the last 25 years (January 1989–January 2014) were collected from the PubMed/MEDLINE database using the given keywords. Of the 330 records, 64 full-text articles (mostly case reports/series) were selected, incorporating clinical data from 78 patients, after screening through duplicates and the given exclusion criteria. With the available evidence, hairy polyps appear more common than generally believed, and are increasingly being recognized as an important, often-missed cause of respiratory distress and feeding difficulty in neonates and infants. Such a child without any apparent cause should be examined with flexible nasopharyngoscope to specifically look for hairy polyps which might be life-threatening, especially when small. The female preponderance as believed today has been found to be an overestimation in this review. These lesions are characteristically composed of mature ectodermal and mesodermal tissue derivatives presenting as heterotopic masses, hence termed choristoma. However, little is known about their origin, and whether they are developmental malformations or primitive teratomas is debatable. Involvement of Eustachian tube and tonsils as predominant subsites and the speculated molecular embryogenesis link hairy polyps to the development of the first and second pharyngeal arches. They are exceptionally rare in adults, but form a distinct entity in this age-group and could be explained as delayed pluripotent cell morphogenesis or focal neoplastic malformations, keeping with the present-day understandings of the expanded “teratoma family”. © 2014, Springer-Verlag Berlin Heidelberg.

Postoperative nausea and vomiting (PONV) are still common following surgery. This is not only distressing to the patient, but increases costs. The thorough understanding of the mechanism of nausea and vomiting and a careful assessment of risk factors provide a rationale for appropriate management of PONV. Strategy to reduce baseline risk and the adoption of a multimodal approach will most likely ensure success in the management of PONV. Copyright © 2011 S. Chatterjee et al. Source

The study examines India's performance based on its publication output in dental sciences during 1999-2008, based on several parameters, including the country annual average growth rate, global publication share & rank among 25 most productive countries of the world, national publication output and impact in terms of average citations per paper, international collaboration output and share and contribution of major collaborative partners, contribution and impact of select top 25 Indian institutions and select top 15 most productive authors, patterns of communication in national and international journals and characteristics of its 45 high cited papers. The study uses 10 years (1999-2008) publications data in dental sciences of India and other countries drawn from Scopus international multidisciplinary bibliographical database. © 2010 Akadémiai Kiadó, Budapest, Hungary.

Forty-one patients with an intercondylar fracture of the humerus (21 recent and 20 ununited) were treated by total elbow arthroplasty using Baksi's recent version of the sloppy hinge from January 2003 to April 2009. Twelve were AO classification type C2 and nine were type C3 recent closed fractures of seven days' mean duration according to Muller classification. Patient's mean age was 64 years. There were 20 nonunions (nine untreated nonunions of a mean of 11 months duration and 11 following failed internal fixation of a mean of 14 months duration); mean patient age was 58 years. The follow up period was 12-88 (mean 55.5) months. Mean arc of postoperative elbow flexion was 25-130° obtained in 39 (95.1%) patients. Mean arc of 65° pronation and 60° supination was obtained in 33(80.5%) patients. According to the Mayo elbow performance score, in the fresh-fracture group, excellent results were seen in 19 (90.5%), good in one (4.8%), and failure in one (4.8%), whereas in the nonunion group, excellent results were obtained in 17 (85%), good in two (10%), and failure in one (5%). Failure in the two patients was due to deep infection requiring prosthesis removal. Other complications were transient ulnar neurapraxia in three, disassembly of the prosthesis in one, patchy heterotopic ossification in two and localised radiolucency around the flanges of the humeral stem in one. © Springer-Verlag 2010.

Schizophrenia is a mental disorder characterized by delusion, hallucination, formal thought disorder, disorganized or catatonic behavior, negative symptoms (e.g. emotional blunting, decreased initiative, impoverished speech etc.) and cognitive dysfunction. Though not described as diagnostic criteria, cognitive dysfunction is the strongest determinant of functional recovery as it has a gradual deteriorating effect on social and occupational functioning. It precedes coincides and outlasts positive symptoms. Among different cognitive abilities it affects attention, memory, processing speed, social cognition and executive function most. Recent studies are showing schizophrenia affects those who have compromised cognitive function or low IQ. Moreover different brain imaging techniques have shown structural and functional abnormality in certain areas. This article has tried to answer few questions like, are cognitive dysfunctions inevitable in schizophrenic patients and if it is then what are the areas what is the nature of affection. It is also important to know how and why they affect the long term outcome of this disorder. © 2015, Bhattacharya. Source
