Evaluation of quality of DNA extracted from buccal swabs for microarray based genotyping.

Buccal cell usage has been shown by many to be a cost effective and safe method to isolate DNA for various biological experiments especially large epidemiological studies (Garcia-Closas et al. Cancer Epidemiol Biomarkers Prev 10:687-696, 2001). Non-invasive DNA collection methods are preferred over phlebotomy in order to increase study participation and compliance in research centers and for sick patients in hospital settings.

Low cost calibrated mechanical noisemaker for hearing screening of neonates in resource constrained settings.

Background & Objectives: There is a need to develop an affordable and reliable tool for hearing screening of neonates in resource constrained, medically underserved areas of developing nations. This study valuates a strategy of health worker based screening of neonates using a low cost mechanical calibrated noisemaker followed up with parental monitoring of age appropriate auditory milestones for detecting severe-profound hearing impairment in infants by 6 months of age.

Methods: A trained health worker under the supervision of a qualified audiologist screened 425 neonates of whom 20 had confirmed severe-profound hearing impairment.

Tracheal resection with end-to-end anastomosis for post-intubation cervical tracheal stenosis: study of 14 cases.

Background And Objectives: The incidence of acquired laryngeal stenosis is increasing. This retrospective study aimed to assess the long term results of circumferential resection with end-to-end tracheal anastomosis for isolated post-intubation stenosis of the cervical trachea, and to review the relevant literature.

Methods: Twelve male and two female patients (aged 16-30 years, mean age 24 years) treated between February 2003 and December 2008 were included.
