چکیده
Parallel rays of light striking the eye in the position of rest are refracted and brought to a focus on the 1 retina. An eye that exhibits this condition is said to be emmetropic (normal). Refractive error or ametropia is said to occur when light rays striking the eye at rest are refracted but, not focused on the retina. Anisometropia is said to occur if there is a 2 difference in the refractive state of the two eyes. A survey in Dambatta district of Kano state, the location of our hospital showed that 2.05% of those examined had low vision and refractive error was 3 the cause in 5%. Uncorrected refractive errors can lead to amblyopia causing serious problems for children and without appropriate optical correction, millions of children can loose life time educational 4 opportunities. A study in Saudi Arabia showed that refractive error is the commonest cause of bilateral 5 visual loss in 56% of children with low vision. The aim of the study is to retrospectively determine the prevalence and different types of refractive errors seen in children (aged 15 years and below) in Aminu Kano Teaching Hospital Kano, Nigeria from January to December, 2007.

Modelling of Telephony Systems with Finite Number of Resources
The paper proposes an analytical method for determining basic traffic characteristics of systems servicing multi-rate overflow traffic streams generated by a finite number of sources. In particular, we describe an optimum solution for the implementation of telephony system. Analytical results of blocking probability calculated using the presented methodology has been compared with the data obta...
متن کاملBat Nipah Virus, Thailand
Surveillance for Nipah virus (NV) was conducted in Thailand's bat population. Immunoglobulin G antibodies to NV were detected with enzyme immunoassay in 82 of 1,304 bats. NV RNA was found in bat saliva and urine. These data suggest the persistence of NV infection in Thai bats.
متن کاملSchistosomiasis Presenting as Colonic Polypoid Masses in a Nigerian Patient
Intestinal Schistosomiasis is a serious disease and is commonly produced by S. mansoni and japonicum. The presence of viable ova of the organism in the colon elicits inflammation, formation of granuloma, ulcers, haemorrhage and colonic fibrosis with subsequent longterm sequelae. Schistosoma mansoni is endemic in the Middle East, Africa, Central and South America. This is a case of a Nigerian wi...
متن کاملSurvey for Bat Lyssaviruses, Thailand
Surveillance for lyssaviruses was conducted among bat populations in 8 provinces in Thailand. In 2002 and 2003, a total of 932 bats of 11 species were captured and released after serum collection. Lyssavirus infection was determined by conducting virus neutralization assays on bat serum samples. Of collected samples, 538 were either hemolysed or insufficient in volume, which left 394 suitable f...
