Abstract. Community-acquired methicillin-resistant Staphylococcus aureus (CA-MRSA) is a pathogen recognized to be distinct in both phenotype and genotype from hospital-acquired MRSA. We have identified CA-MRSA cases in Universiti Kebangsaan Malaysia Medical Centre, Kuala Lumpur, Malaysia, including their antibiotic susceptibility patterns and genotypic characteristics. Cases were identified during January to December 2009 from routine clinical specimens, where culture and antibiotic susceptibility results yielded pauci-resistant MRSA isolates suspected as being CA-MRSA. The patients' clinical data were collected and their specimens were sent for molecular confirmation and analysis. Five cases of CA-MRSA were identified, which had a multi-sensitive pattern on antibiotic susceptibility tests and were resistant to only penicillin and oxacillin. All cases were skin and soft-tissue infections, including diabetic foot with gangrene, infected scalp hematoma, philtrum abscess in a healthcare worker, thrombophlebitis complicated with abscess and infected bedsore. All five cases were confirmed MRSA by detection of mecA. SCCmec typing (ccr and mec complex) revealed SCCmec type IV for all cases except the infected bedsore case. Panton-Valentine leukocidin gene was positive in all isolates. As clinical features among methicillin-sensitive Staphylococcus aureus, CA-MRSA and "nosocomial CA-MRSA" are indistinct, early recognition is necessary in order to initiate appropriate antibiotics and infection control measures. Continual surveillance of pauci-resistant MRSA and molecular analysis are necessary in order to identify emerging strains as well as their epidemiology and transmission, both in the community and in healthcare setting.

A Specialist Clinic was commenced in August 1983, from the Medical School at Universiti Sains Malaysia, Penang, Malaysia to assess: 1) the present control and 2) the incidence of complications in a diabetic population already receiving primary health care at Penang General Hospital. The ethnic groups among the diabetics were Chinese (39%), Malays (26%) and Indian (35%). There was a greater percentage of Indians than would be expected from the ethnic distribution of the population of Penang. The results of the first 100 (43 males and 57 females) non-insulin dependent diabetic patients are reviewed. The mean age was 54 years, 41% had relatives with diabetes, and all were taking oral agents. The diet comprehension and compliance were poor. 65% of the group, 54% of males and 75% of females were obese. The mean blood glucose was 11 m.mols/l (fasting) and 12.8 m.mols/1 (2 hours post prandial). The complications seen in the 100 diabetics were: albuminurea 41, skin infection 37, cataracts 35, hypertension 32, peripheral sensory neuropathy 32, retinopathy 22, ischaemic heart disease 19, autonomic neuropathy 10, impaired renal function 4 (urea or creatinine elevated), foot ulcer 2 and gangrene 1. Urinalysis for glucose at the Clinic showed very little correlation with blood glucose at the same time. Nine out of 43 males admitted to impotence on questioning. Comparisons of findings in Penang were made with recent studies in Singapore and Hong Kong.
