The incidence of methicillin-resistant Staphylococcus aureus (MRSA) infections in intensive care units in Malaysia is significant. Invasive MRSA infections are commonly treated with vancomycin. In clinical practice, the serum vancomycin trough concentration is used as a surrogate marker of vancomycin efficacy. A low concentration of vancomycin may result in less effective therapy and increase the risk of bacterial resistance. We evaluated the relationship between the resolution of MRSA infections and trough concentrations of vancomycin. ⋯ In this critically ill population, a vancomycin dose of 15 mg/kg/day was found sufficient to produce optimal trough concentrations to eradicate the MRSA infection. This study demonstrated the significant relationship between response to treatment of MRSA infection and serum vancomycin trough concentrations.

New, effective antibiotics are only likely to become available in 15 - 20 years. To prevent deaths from untreatable Gram-negative infections in South Africa, the rights of any doctor, whether in general or in hospital practice, to indiscriminately prescribe whatever antibiotic they wish, and in whatever fashion, must be challenged. Furthermore, although prevention of the emergence and subsequent spread of carbapenem-resistant Enterobacteriaceae (CRE) has focused on acute and chronic care facilities and inter alia on antibiotic exposure in these institutions, CRE may soon become an issue within entire communities, highlighting a role for public health authorities in CRE prevention efforts.

Allergic rhinitis (AR) is an important disease in South Africa. The South African Allergic Rhinitis Working Group (SAARWG) has published previous guidelines for AR diagnosis and management. Areas of concern have arisen that require additional information, including the management of AR in infancy, appropriate and inappropriate allergy testing, cost of AR management, diagnosis and distinguishing the condition from sinusitis, use of over-the-counter medications, and the concept of the 'united airway'. ⋯ The SAARWG proposed an algorithm for the diagnosis and management of rhinitis in South Africa. AR is common, important and troubling to patients; therefore, every effort should be made to target therapy correctly. Patient education is important in the management of AR.
