Introduction:Cutaneous adverse drug reactions are one of the most common adverse drug reactions. Publicationson clinical correlation between cutaneous presentations and causative agents are limited among thelocal population. This study aims to determine the clinical presentations of cutaneous adverse drugreactions and the causative drugs in the local population.Methods:A retrospective, cross sectional study was conducted from the pharmacy cutaneous adverse drugreaction database from January 2014 to December 2016 in Tawau, Keningau & Queen Elizabeth (KotaKinabalu) Hospitals.Results:A total of 859 cases of cutaneous adverse drug reactions were identified. Out of these, 53.3% (n=458)were females and 46.7% (n=401) were males. The mean age was 36 years old. Majority of patients were20-29 years old (16.6%) followed by 50-59 years old (15.1%). Most of the cases were reported amongthe Chinese community (16.4%), followed by the Malay (15.9%), Dusun (14.7%) and Bajau (14.0%)populations. The most common cutaneous manifestations were urticaria and or angioedema (49%, n=421) and maculopapular rash (39.6%, n=340). Severe cutaneous adverse reactions (SCAR) constituted2.8% in total. The major causative agent was antibiotic which accounted for 55.1% (n=473), followedby nonsteroidal anti-inflammatory drugs (NSAIDs), 28.1% (n=241) and analgesics, 10.8% (n=93).Conclusion:The types of cutaneous manifestations and causative drugs in Sabah are similar to those reported inother states of the country and abroad. This study provides evidence of local cutaneous adverse drugreaction characteristics in different ethnic group.

ABSTRACT Presently there is a lack of health-related quality of life (HRQOL) measure and its corresponding utility values for oral cancer and oral potentially malignant disorders (OPMD). This limits patient-centered outcomes for cost-effectiveness evaluations. The study aimed to determine post-treatment HRQOL of patients and ascertained differences between OPMD, early and late-stage oral cancer. A cross-sectional survey was conducted among patients in oral maxillofacial specialist clinics in two public tertiary hospitals. Consented participants were required to complete the EQ-5D-5L questionnaire with the EQ Visual Analogue System (VAS). Kruskal-Wallis test was used to explore differences in values between stages. Multiple linear regression was used to explore factors that influenced the HRQOL. A total of 50 OPMD and 52 oral cancer patients were surveyed. The mean EQ-5D-5L health utility values was 0.842 (n = 50, SD = 0.139), 0.822 (n = 10, SD = 0.150) and 0.626 (n = 42, SD = 0.310) for OPMD, early- and late-stage cancer, respectively. The mean values of the EQ-5D-5L index and EQ-VAS scale showed significant differences between groups and between early- and late-stage cancer with good discriminative properties. Results of the multiple linear regression indicated that ethnicity, income, residency, diagnosis, and treatment modality were able to significantly account for 25% of EQ-5D-5L utility values, F(10,91) = 3.83, p < 0.001, R2 = 0.360. Indian ethnicity, rural location, income less than RM4,360, late-stage cancer, and multi-modal therapies were all predictors of poorer HRQOL. This study evidenced disease severity and treatment modality to greatly impact the HRQOL of patients, in addition to socio-demographic factors such as ethnicity and income.
