RESUMEN
Objective: To compare three growth references that can be used to assess the weight status of school-aged youth living in India, with a particular focus on identifying overweight and obese youth. Study Design: Cross-sectional study. Kappa scores were used to measure agreement between growth references. Regression models were used to test for differences in weight status by grade level, gender, and school type, using each growth reference. Setting: Private (n=4) and Government schools (n=4) in Delhi, India. Participants: Students (n=1818) in eighth and tenth grade attending the schools. Main outcome measures: Weight status was derived using age- and gender-specific cut-points provided by: (a) a national growth reference specific to India; (b) an international reference recommended by the International Obesity Task Force (IOTF); and (c) a new international reference recommended by the World Health Organization (WHO). Results: The IOTF reference consistently classified participants in a lower weight status category, compared with the national reference (κ=0.57) and the WHO reference (κ=0.69). The agreement between the WHO and the national references was higher (κ=0.84). Conclusions: To date, all published studies of childhood obesity in India have used the IOTF reference, the national reference, or an old WHO reference to measure weight status among school-going youth. The new WHO reference may be a better choice. Compared to the IOTF reference, it does not appear to underestimate obesity and can still be used to compare trends, globally.
RESUMEN
This cross-sectional study was conducted in different sizes of pars tensa perforation in patients with chronic suppurative otitis media (CSOM) tubo-tympanic type undergoing myringoplasty. A total of 50 patients were recruited from the outpatient Department of Otorhinolaryngology - Head and Neck Surgery in TU Teaching Hospital from June 2003 to May 2004. Cases of CSOM tubo-tympanic type with dry central perforation, conductive type of hearing loss were subjected to myringoplasty. Preoperative audiometric evaluations were done. While operating under microscope diameter of perforations were measured and perforations were grouped according to the size. This study showed that the hearing loss was found to be more at lower frequencies and less as the frequencies increased. Hearing loss is more marked at lower frequencies as compared to higher frequencies, irrespective any size or location of perforation of pars tensa.

This is a case report of myiasis in modified radical mastoidectomy cavity in a 48 years old male presented in the Department of ENT and Head and Neck Surgery, T.U.Teaching Hospital, Katmandu, Nepal. Around 50 maggots were removed from his mastoid cavity. Patient was managed with turpentine oil and antibiotics which was given to prevent secondary infection. Literature search revealed only one case report of Myiasis infestation in a postoperative mastoid cavity.

This prospective study was done to assess the level of preoperative hearing impairment in different sizes of pars tensa perforation in patients with chronic suppurative otitis media (CSOM) tubo-tympanic type undergoing myringoplasty. A total of 50 patients were recruited from the outpatient Department of Otorhinolaryngology - Head and Neck Surgery from June 2003 to May 2004. Cases of CSOM tubo-tympanic type with dry central perforation, conductive type of hearing loss were subjected to myringoplasty. Preoperative audiometric evaluations were done. While operating under microscope diameter of perforations were measured and perforations were grouped according to the size. It was observed that greater hearing loss was reported in group D perforation (44 dB), where as in group A, it was 31 dBHL. The average hearing loss at 500 Hz was 46.40 dB, at 1000 Hz was 30.90 dB and at 2000 Hz it was 31.9 dB. This shows that the hearing loss is more at lower frequencies and less as the frequencies increase. This study shows that as the size of perforation is increased, the hearing loss also increases. The hearing loss is more marked at lower frequencies as compared to higher frequencies.
