Severe adverse cutaneous drug reactions: The 5 year Kuala Lumpur Hospital experience

Introduction: Stevens Johnson syndrome (SJS), Stevens Johnson Syndrome - toxic epidermal necrolysis overlap syndrome (SJS-TEN overlap), toxic epidermal necrolysis (TEN) and drug-induced hypersensitivity syndrome (DHS) are well known severe adverse cutaneous drug reactions (SACDRs). All clinicians are responsible for the diagnosis and management of SACDR. Objective: To retrospectively review the clinical patterns, management strategies and outcome of 134 patients with severe adverse cutaneous drug reactions managed at the Department of Dermatology, Kuala Lumpur Hospital between 2006 and 2010. Results: The mean age of presentation was 44.8 years (13-83). The male: female ratio was 1:1. There were 68 cases (50.7%) of SJS, 10 cases (7.5%) SJS-TEN overlap, 32 cases (23.9%) TEN and 24 cases (17.9%) DHS. The five commonest drugs associated with SACDRs were allopurinol (26.9%), carbamazepine (13.4%), phenytoin (9.7%), non-steroidal anti-inflammatory drugs (11.2%) and co-trimoxazole (7.5%). The mean duration of drug exposure before the onset of reaction was 2.8 weeks. A hundred and thirty patients (97%) were managed as in-patient. The mean duration of in-patient stay was 12.4 days. All identified culprit drugs were withheld. Systemic corticosteroids was given to 96% cases of DHS with mean duration of 9.7 weeks; 52.9% of SJS with mean duration of 2.8 weeks; 60% of SJS-TEN overlap with mean duration of 2.3 weeks; and 62.5% of TEN with mean duration of 3.3 weeks. Thirteen patients (42%) with TEN were treated with intravenous immunoglobulin. Eight patients (6%) died, of which 7 were TEN and one DHS. Conclusion: SACDRs are life-threatening emergencies which not only results in significant morbidity and mortality; but also potentially increases the health care cost and burden. Clinicians should recognize high risk medications and prescribe them with great caution.

Monitoring performance of specialists in conducting skin biopsy using Cumulative Sum (CUSUM) technique: Results of a pilot study in Kuala Lumpur Hospital

Introduction: Cumulative Sum (CUSUM) technique is an objective statistical method used in assessing and monitoring doctor’s performance. It has been incorporated into quality improvement strategies in clinical services by the Ministry of Health, Malaysia. A pilot study was aimed at evaluating its usefulness in monitoring the performance of specialists in conducting skin biopsy. Methods: All skin biopsies performed by specialists in the Department of Dermatology, Kuala Lumpur Hospital from September 2009 to April 2011 were included in the prospective observational study. Outcomes monitored were wound complications within 14 days post-biopsy, and tissue sample being adequate and representative for histopathological interpretation. CUSUM scores of each consecutive biopsy performed by individual specialist were calculated and charted with the eCUSUM web application (https://app.acrm.org.my/eCUSUM). Results: A total of 870 skin biopsies were performed by 15 clinical specialists and three consultant dermatologists during the study period. Wound infection or dehiscence were reported in 13 (4.1%) of the 318 biopsy wounds evaluated. Tissue samples were inadequate in 10 (1.2%) and non-representative in 11 (1.3%) of the 817 histopathological reports evaluated. No learning curve was observed in all CUSUM charts indicating that all specialists had been adequately trained for the procedure. However, out-of-control signals indicating unacceptable wound complication rates and either inadequate or non-representative tissue samples were detected in three clinical specialists. Feedback and counseling were given while monitoring was continued. Conclusions: The CUSUM method is a useful performance monitoring tool which is able to promptly detect unacceptable outcomes in skin biopsy. It is invaluable in the supervision of junior doctors and trainees as well as self-monitoring for the trained specialists.

The impact of acne vulgaris on the quality of life in Sarawak,Malaysia

Background There is lack of data on the impact of acne vulgaris on the quality of life in Malaysia. Thus, this study was done to determine the impact of acne vulgaris on the quality of life in Sarawak, Malaysia and to examine its relationship with the severity of acne. Methods A cross-sectional study of 173 patients in 3 dermatology clinics in Sarawak utilizing the dermatology life quality index (DLQI). Results The mean DLQI score was 4.1. Patients with family income < RM 3000 had higher mean DLQI scores (4.8 vs. 3.2, p = 0.02). There was also a tendency for indigenous groups to have higher DLQI scores compared to Chinese although it was not statistically significant (4.5 vs. 3.5, p = 0.15). Females were significantly more impaired in the domains of symptoms and feelings (2.1 vs. 1.5, p = 0.02); and work and school (0.3 vs. 0.2, p = 0.04). DLQI was weakly correlated with acne severity in patients with mild acne (Pearson coefficient = 0.27, p = 0.01) but become insignificant for patients with moderate and severe acne. No correlation was seen between DLQI and age of patients. Conclusion Acne vulgaris has a quality of life impact similar to that of psoriasis in Sarawak and must be addressed. Health care providers and administrators should view acne as a psychologically disabling disease requiring optimal management and resource allocation. Education of junior doctors and medical student on this issue is also important.

Primary Cutaneous Anaplastic Large Cell Lymphoma: Report of 3 cases from Hospital Kuala Lumpur

Primary cutaneous anaplastic large cell lymphoma (c-ALCL) is an uncommon type of cutaneous T cell lymphoma currently classified as one of the CD30+ lymphoproliferative disorders of the skin under the WHO-EORTC classification1. We describe a series of three patients with c-ALCL from 2005-2009 in the Department of Dermatology, Hospital Kuala Lumpur.
