A first record from Thailand of human external ophthalmomyiasis due to Oestrus ovis.

A case of external ophthalmomyiasis caused by Oestrus ovis was first reported from Lopburi Province, Central part of Thailand, in January, 1997. A 18-year-old man presented with a several hours history of foreign body sensation in his left eye accompanied by irritation. Eight Oestrus ovis first-instar larvae were removed from lower palpebral conjunctiva. Symptoms and clinical signs resolved in 24 hours after mechanical removal of the larvae. There was no history of contact fly and domestic animals. The larvae were identified by light microscopic examination.

Cryptosporidiosis in Siriraj Hospital, Bangkok, Thailand.

During January to July 1986, 1,500 fecal specimens from out and in-patients attending Siriraj Hospital, Bangkok were examined for Cryptosporidium oocysts by modified acid fast technique. Eight were found to be positive. The prevalence of cryptosporidiosis was 3.7% in children with acute diarrhoea. Medical records of the patients showed that the main clinical presentation was acute diarrhoea with fever for one to 7 days duration. Stool examinations and cultures revealed no white blood cells or parasites or other enteropathogenic bacteria. All recovered within two weeks. The study suggest that Cryptosporidium is a relatively common nonviral cause of acute diarrhoea in young children and routine laboratory study to detect Cryptosporidium may be justified.
