1.A 5-year retrospective study on onychomycosis and its causative organisms in University Malaya Medical Centre (UMMC)
Malaysian Journal of Dermatology 2009;23(-):11-15
Introduction Onychomyosis is a common infection of the nails, caused by dermatophytes, nondermatophyte
moulds or yeasts. There are four main types of onychomycosis which include lateral
and distal onychomycosis, proximal onychomycosis, superficial white and total dystrophic
onychomycosis. We performed a retrospective analysis looking into the recent trends of
onychomycosis in a University Hospital in Malaysia.
Materials and methods Data was collected from all patients who had their nail clippings cultured
for fungal infection from January 2004 to December 2008, and were analysed.
Results There were 272 nail specimens in total. The majority of specimens were from adults
(65.8%), followed by the elderly (23.9%) and children and adolescents made up 10.3%. The mean
age of the study population was 49.9 ± 19SD years. Of the 189 specimens with positive fungal
culture, 110 (40.4%) were non-dermatophyte moulds, followed by yeasts predominantly Candida
species (17.6%), 3 (1.1%) were dermatophytes, and 28 (10.3%) were a mixed infection of
dermatophytes, non-dermatophyte moulds and yeasts.
Conclusion From this study, it was found that onychomycosis in our hospital from 2004 to 2008
were mainly caused by non-dermatophyte moulds. Treatment may be challenging as nondermatophyte
onychomycosis are more resistant to treatment.

Cat fleas were reported to attack human in RPR Batu Kawa, a housing area about 3 km from Kuching town, resulting in an outbreak. A total of 19 people (10 adults and 9 children) were attacked by fleas. They presented with red spots, slightly raised (swollen) and irritation of skin, mostly found on the ankles and legs. The first 4 cases were reported on 29 September 2007 and the last case was on 17 November 2007. The remaining 12 cases which represent the majority of cases reported on 4th October 2007. The study conducted based mainly on field investigation and flea sampling from animals on field at that moment to find out the causes of the disease spread. Flea samples from human and cats were found to be Ctenocephalides felis; which is the most prevalent species in the world. However, no fleas were found on dog, rabbit and rat. This is the first reported case in Kuching; the study was carried out to determine the cause and the epidemiological pattern of the disease. This is important, because cat flea might attack human especially if house owners fail to monitor their pets and practice proper sanitation method to avoid the presence of cat flea larvae at home.
