Publication Fallopian Tube Papilloma – Case Report of a Rare Tumor(Kathmandu University, 2013) Narasimhaiah, A; Ansari, M; Haritwal, A; Awasthi, SABSTRACT Fallopian tube neoplasms are rare. We report a rare case of fallopian tube papilloma discovered incidentally in a 45 year old female, operated for procidentia. Right tube was dilated at the infundibular region, with friable grey white tissue in the lumen. Microscopy showed delicate branching papillae lined by a single layer of epithelium resembling tubal lining. There were no features to suggest a reactive hyperplasia in response to inflammation or of aggressive behaviour.

So, school screening records were used to obtain data useful for planning of refractive services. Methods Data are provided from school screening conducted by Geta Eye Hospital during February/March 2008. The cases with complete data sets on visual acuity, refractive error and age were included and analyzed using computer software. Results Of 1165 children (mean age 11.6±2.5 years) examined, 98.8% (n= 1151) had uncorrected visual acuity of 6/9 and better in at least one eye whereas 1.2% (n= 14) had acuity 6/12 and worse in both eyes. Among them, either eye of 9 children improved to 6/9 and better with correction. However, visual acuity was 6/12 and worse in both eyes of 5 children even after correction. There were 24 children with refractive errors (myopia, 1.54%; n= 18 and hypermetropia, 0.51%; n=6) in at least one eye. The spherical equivalent refraction was not significantly different with age and gender. Conclusions The incidence of reduced vision and refractive errors among school children of this semi rural district were low.

Objective To validate recent evidence from India of the effectiveness and cost of alternate school visual acuity screening models involving all class teachers (ACTs) versus a few selected teachers (STs). Method This was a prospective cluster randomized controlled study. The sample size was 5000 students. Five schools were randomly selected for the all-class teachers or intervention arm and four schools for selected teachers or standard arm. Teachers from both arms were trained to identify children aged 6 years and above with Snellen visual acuity 6/9 or worse in either eye as well as obvious ocular abnormalities and refer them to an ophthalmic team. The screen positive and negative children as well as cost for screening were calculated in STATA software (version 11.0; StataCorp, Texas, USA). Result All class teachers (80 teachers) screened 3713 children and STs (9 teachers) screened 2064 children aged 6 to 15 years. All class teachers had better sensitivity, 95.1% (95% CI: 91.9-98.2) and specificity, 92.8% (95% CI: 92.0-93.6) compared to selected teachers: sensitivity, 73.2% (95% CI: 64.4-82.0) and specificity, 85.3% (95% CI: 83.8- 86.7). The cost of screening per child with refractive error and or other ocular abnormalities was $3.05 for all class teachers and $ 5.29 for selected teachers. Conclusion A school vision screening involving all class teachers in Nepal was more accurate than selected teachers in identifying refractive error and or other ocular abnormalities at approximately 60% of the cost.
