Knowledge about HIV transmission, behavior and self- perception about risk of getting HIV among men
(Institute of Medicine, 2012) Oli, NL
Abstract
Introduction: In spite on a lot of work done by nongovernmental organizations of men having sex with men (MSM) with the collaboration of Nepal government there is high prevalence of unprotected anal sex with a high incidence of sexual partner change. The purpose of this study was to explore knowledge about Human Immunodeficiency Virus (HIV) transmission, behavior and self-perception about risk of getting HIV among men having sex with men in Kathmandu Valley.
Methods: This is cross-sectional explorative study. Study was carried out between July 2010 and December 2010 in 97 men having sex with men in Kathmandu Valley using snow balling sampling technique. The verbal consent was taken and the respondents were interviewed using structured questionnaire.
Results: Although overall knowledge regarding HIV/AIDS and Sexual transmitted Infections (STI) is high some misconception about way of transmission is present. Majority of respondents still practiced unsafe sexual behaviors, which included multiple sex partners, irregular use of condom, frequent and regular anal sex, sex in exchange of money. More than half of them considered that they had little risk of getting HIV/AIDS.
Conclusion: Sexual behavior of men having sex with men needs to be further addressed in order to promote safer and responsible sexual behavior.

Sinonasal Inverted Papilloma
(Institute of Medicine, 2012) Thapa, N; Pradhan, B
Abstract
Introduction: Sinonasal inverted papilloma is a rare tumour comprising about 0.5-4% of total nose and paranasal sinus tumours. Though various factors have been implicated its exact cause is unknown. This longitudinal, prospective study was carried out to find out demographical profile, association of this tumour with smoking, occupation, variation with ethnic races and outcome of surgery.
Methods: This study was carried out in the department of ENT-HNS, Tribhuvan University Teaching Hospital, Maharajgunj, Kathmandu from April, 2005 to March, 2011.
Result: Out of 34 patients, there were 25 male and 9 female with ratio of 2.78:1. Age of the patients ranged from 14-76 years with median age of 51.5±2.74 SE years. Disease was more common in 4th to 7th decade. It was common in farmers (20). Eighteen patients were smoker and 16 nonsmoker. The disease was more common in mongoloids than in Indo-aryans. Out of 16 patients having stage III disease, 9 were smoker and 7 nonsmoker. Eighteen patients underwent endoscopic medial maxillectomy and 15 patients underwent medial maxillectomy via lateral rhinotomy approach. One patient who had bilateral disease underwent medial maxillectomy via lateral rhinotomy on the left side and endoscopically on the right side. There was recurrence of tumour in 2 patients who underwent surgery via lateral rhinotomy approach whereas in 1 patient who underwent surgery endoscopically.
Conclusion: This study showed that sinonasal inverted papilloma was common in mongoloids than in Indo-aryans and farmers but no association with smoking. Endoscopic medial maxillectomy has less reccurence of tumour in comparison to lateral rhinotomy approach.

Tear Film Evaluation in Contact Lens Wearers and Non Wearers
(Institute of Medicine, 2012) Shrestha, G.S; Sujakhu, D; Shrestha, J.B; Shrestha, J.K
Abstract
Background: Dry eye symptoms are more frequent in contact lens wearers than in non wearers. Dry eye is considered relatively common in contact lens wearers than non-wearers. However, there was no any report in our clinical setting that compared and addressed the issue related to dry eye and its symptom in contact lens wearers. The present study was conducted to compare pre-ocular tear film in contact lens wearers (CLW) and contact lens non wearers (CLNW), and evaluate the relationship between clinical and subjective assessment of dry eye symptoms.
Methods: It was a comparative study conducted among 131 subjects (262 eyes) attended in the contact lens clinic at BP Koirala Lions Center for the Ophthalmic Studies. Sixty five were daily soft contact lens wearers; sixty-six were non wearers.
Tear function assessment included non- invasive tear break up time, invasive tear break up time, tear prism height and Schirmer II test. Subjective assessment of dry eye symptoms was carried out using McMonnies questionnaires.
Results: Mean age of CLNW was 23.01± 5.53 and CLW was 23.6± 4.61. Female (89 subjects) visited more than male (42 subjects) in contact lens clinic. Mean symptom score in CLW was significantly higher than CLNW (p<0.001). But, distribution of symptomatology was not significantly different in both groups. Symptomatic subjects were elder (p<0.001) and female (p<0.05) in CLNW and only elder subjects in CLW. Tear function tests were significantly lower in symptomatic subjects in CLW and CLNW; Overall tear function test scores were also lower in CLW than CLNW. Tear function tests scores were insignificantly different in male and female. Coefficient of correlation was positive and weak for all tear function tests scores.
Conclusions: Though, tear function tests scores were reduced in CLW than CLNW, dry eye symptomatology was almost similar. Subjective assessment of symptoms is as important as clinical tests.
