METHODS: This was a comparative case-control study done on patients in Hospital Universiti Sains Malaysia (Hospital USM), requiring split-thickness skin grafting, whereby, the skin graft donor site was divided to almost equal halves, and applied with both gamat-based gel on one side, with Duoderm® hydrogel on the other side. The epithelialization of the wounds was observed and compared on days 10, 14 and 21. Pain score, and pruritus score were also observed. Repeated measure analysis of variance (ANOVA) test and Paired t-test was used to test statistical significance accordingly.
RESULTS: No significant differences were seen in rates of epithelialization of wounds on days 10, 14 and 21 (p > 0.01). No significant difference was also seen in the pain score and pruritus score (p > 0.01).
CONCLUSIONS: A gamat-based gel is comparable to conventional hydrogels in treatment of split-skin graft donor site. No adverse effects were observed in either group.
MATERIALS AND METHODS: In the initiation phase, the mice received a single dose of 100µl/100 µg DMBA (group I-V) or 100µl acetone (group VI) topically on the dorsal shaved skin area followed by the promotion phase involving treatment with the respective test solutions (100 µl of acetone, 10 mg/kg curcumin or MEMM (30, 100 and 300mg/kg)) for 30 min followed by the topical application of tumour promoter (100µl croton oil). Tumors were examined weekly and the experiment lasted for 15 weeks.
RESULTS: MEMM and curcumin significantly (p<0.05) reduced the tumour burden, tumour incidence and tumour volume, which were further supported by the histopathological findings.
CONCLUSION: MEMM demonstrated chemoprevention possibly via its antioxidant and anti-inflammatory activities, and the action of flavonoids like quercitrin.
OBJECTIVE: To determine the clinical characteristics, culprit drugs and outcome of patients with AGEP.
METHODS: A retrospective note review of all AGEP patients seen from 2001-2015.
RESULTS: Among 21 AGEP patients, 76% were Malays, 9.5% Chinese, 9.5% Indians, and 5% Iban. Sixteen were females and 5 were males. Median age of patients was 40 years (IQR: 26). The main culprit drug was amoxicillin (10 cases), followed by cloxacillin (three cases), phenytoin (two cases) and one case each of carbamazepine, sulphasalazine, allopurinol, cephalexin, ceftriaxone, celecoxib and herbal product. The median time from drug initiation to onset of AGEP was 3 days (IQR: 5.5). Fever was documented in 52.4 %, mucosal involvement 9.5%, purpura 4.7% and blisters 4.7%. Neutrophilia was observed in 63.6% of patients and eosinophilia in 28.5%. While most patients required admission (67%), all achieved complete recovery within 15 days without any sequela.
CONCLUSIONS: AGEP predominantly affects Malay females in this study. The most common culprit drug was amoxicillin. Our patients exhibited the classic clinical manifestations of AGEP and confirmed the generally benign nature of this reaction upon drug withdrawal. Although the overall prognosis is good, prompt diagnosis of AGEP is important because drug withdrawal is the mainstay therapy.
