Intestinal parasitosis among subjects undergoing cataract surgery at the eye camps in rural hilly areas of Nepal.

Present study investigated the intestinal parasitosis among 221 subjects undergoing cataract surgery (M: 129 and F: 92; aged 13-86 years) at the eye camps in three rural hilly districts (Ramechhap, Sindhupalchok and Dhading) in 2006. Stool samples collected in clean, dry, screw capped plastic containers were examined locally by direct smear technique and anti-parasitic drugs were distributed to parasite positive subjects. The remaining stool samples were fixed with 10% formal-saline, transported to Shi-Gan Health Foundation/Nat'l Inst of Trop Med and Public Health Research, Kathmandu and re-examined by formal-ether sedimentation technique. A total of 148 samples (66.9%) were positive for some kind of intestinal parasites (F: 68.5% and M: 65.9%; P > 0.05). Ramechhap (Manthali) and Sindhupalchok (Chautara) had higher positive rate (71.8% and 70.7%, respectively) than in Dhading (Salyantar) (60.0%) (P > 0.05). Tibeto-Burman (indigenous nationalities) ethnic group had highest positive rate (70.1%) compared with Indo-Aryan (64.7%) and Dalits (57.7%). Subjects without toilet (latrine) had marginally higher positive rate (69.7%) than those having toilet at their home (65.5) (P> 0 .05). Age was independent of positive rate. Vegetarians had marginally higher parasitic infection rate compared to their non-vegetarian counterparts. Helminths were more common than protozoa. Overall, hookworm was the commonest parasite detected. However, Ascaris was common in Dhading District. Entamoeba histolytica was most common among protozoa and was followed by Cyclospora and others.

Involuntary human bite to the eyebrow.

Human bites to the face are very rare and only one case of human bite to the eyebrow has so far been reported. The final functional and cosmetic result of reconstruction mainly depends on the size of the injury, the viability of the tissue and the promptness of surgical intervention. We here present one case of human bite to the eyebrow that resulted in complete avulsion and loss of tissue due to delayed presentation to the hospital. The lesion was reconstructed in two stages with good functional and decent cosmetic outcome. Unfortunately long term follow up was not possible for this patient.
