BACKGROUND: The mainstay of treatment for carbuncles involves the early administration of antibiotics in combination with surgical intervention. The conventional saucerisation, or incision and drainage, under normal circumstances results in moderate to large wounds, which may need secondary surgery such as skin grafting, resulting in a longer duration of wound healing and jeopardising cosmetic outcome.

CASE REPORTS: The reported three cases presented with extensive carbuncles over the chin, face and lips region. In addition to early commencement of intravenous antibiotics, the pus was drained, with minimal incision and conservative wound debridement, with the aim of maximal skin conservation. This was followed by thrice-daily irrigation with antibiotic-containing solution for a minimum of 2 consecutive days. The wounds healed within two to four weeks, without major cosmetic compromise.

BACKGROUND: With increasing demand for hospitals to provide end-of-life care, the low quality of palliative care provided in hospital settings is an issue of growing concern in developing countries. Most dying patients receive their care from general nurses, irrespective of the nurses' specialty or level of training.

METHOD: A structured cross-sectional questionnaire survey was conducted of 553 nurses working at a teaching hospital in Malaysia.

RESULTS: The mean scores for nurses' knowledge about end-of-life care, their attitudes towards end-of-life care and the perceived quality of end-of-life care were low. The factors identified as significantly associated with the quality of end-of-life care were nurses' levels of knowledge and their attitudes towards end-of-life care.

DISCUSSION: Factors that contributed to the low quality of end-of-life care were inadequate knowledge and negative attitudes. These findings may reflect that end-of-life care education is not well integrated into nursing education.

CONCLUSION: The findings of this study suggest that there is a need to increase the nurses' level of knowledge and improve their attitude towards end-of-life care in order to enhance the quality of care provided to dying patients.

METHODS: The Filipino β-deletion was identified using gap-polymerase chain reaction (PCR) in the parents of transfusion dependent β-thalassaemia patients who were homozygous for the Filipino β-deletion in the indigenous population of Sabah, Malaysia. Hb subtypes were quantified on the BioRad Variant II Hb analyser. Concurrent α-thalassaemia was identified by multiplex gap-PCR for deletions and amplification refractory mutation system (ARMS)-PCR for non-deletional mutations.

RESULTS: The mean HbA2 level for Filipino β-thalassaemia trait was 5.9 ± 0.47 and with coinheritance of α-thalassaemia was 6.3 ± 0.44 (-α heterozygous) and 6.7 ± 0.36 (-α homozygous). The HbA2 levels were all >4% in keeping with the findings of classical β-thalassaemia trait and significantly higher than levels seen in non-deletional forms of β-thalassaemia.

METHODS: B. subtilis was exposed to 5 to 150 μg/mL of ZnO NPs for 24 h. The parameters employed to evaluate the antimicrobial potential of ZnO NPs were the growth inhibitory effect on B. subtilis, the surface interaction of ZnO NPs on the bacterial cell wall, and also the morphological alterations in B. subtilis induced by ZnO NPs.

RESULTS: The results demonstrated a significant (p <0.05) inhibition of ZnO NPs on B. subtilis growth and it was in a dose-dependent manner for all the tested concentrations of ZnO NPs from 5 to 150 μg/mL at 24 h. Fourier transformed infrared (FTIR) spectrum confirmed the involvement of polysaccharides and polypeptides of bacterial cell wall in surface binding of ZnO NPs on bacteria. The scanning electron microscopy (SEM) was used to visualize the morphological changes, B. subtilis illustrated several surface alterations such as distortion of cell membrane, roughening of cell surface, aggregation and bending of cells, as well as, the cell rupture upon interacting with ZnO NPs for 24 h.
