Abstract Introduction: Other than nickel, fragrance and rubber, preservatives are well known sensitizers. Objectives: To study the pattern of preservative allergy among patients patch tested at Patch Test Unit Selayang Hospital. Materials & Methods: We conducted a retrospective analysis of the data of all the patients patch tested with preservative sensitizers present in the European Baseline Series and other commercial series in Selayang Hospital from January 2011 to December 2011. Results: 243 patients were patch tested. 28.4% of the patients had a positive reaction to one or more of the preservative sensitizers. Paraben mix was the most frequently positive allergen (11.8%). 17.8% of the Indians had paraben allergy, as compared to 11.3% of Malays and 11.2% of Chinese. Females were more significantly associated with a positive reaction to one or more of the preservative sensitizers (p=0.010). A younger age group (<35) was more significantly associated with formaldehyde allergy. “Face and upper limbs combined” presentation was significantly associated with a positive reaction to formaldehyde and methylchloroisothiazolinone/ methylisothiazolinone (p=0.042 and p<0.001 respectively). Conclusion: Our data differ from most other countries in that paraben mix was the most frequently positive preservative sensitizer and that younger age group was significantly associated with sensitization to formaldehyde.

Introduction: DRESS is an uncommon severe cutaneous adverse drug reaction, which is under recognized. In this review, we aim to study the clinical characteristics of patients with DRESS that presented to our hospital. Methods: We conducted a retrospective analysis on the data of all the patients with DRESS from January 2006 to December 2012 in Selayang Hospital. Results: Twenty-one patients were included with median age of 33 and male to female ratio of 1:1. Allopurinol was the most frequent causative drug followed by anti-tuberculous drugs. The mean latency period was 28.6 days. All patients had macula-papular rash of which 6 progressed to erythroderma. Liver was the most frequent extra cutaneous organ involvement with median peak alanine transaminase of 746 iu/l, (range 45-3677) and median peak aspartate transaminase of 632 iu/l (range 30-3136). Six patients (28.5%) had acute liver failure. The mainstay of treatment was systemic corticosteroid. Mortality rate was 23.8%. Conclusion: DRESS is a severe cutaneous adverse drug reaction with a myriad of clinical presentation and is associated with mortality. Our series has higher mortality compared to most other reported studies, most probably due to referral bias. Early recognition is crucial.

Introduction: Peripheral arterial disease(PAD) and abdominal aortic aneurysm(AAA) are two important underdiagnosed vascular pathologies. As they share common risk factors with coronary arterial disease, we conducted a study to look at their prevalence among patients with acute coronary syndrome(ACS). Materials and Methods: Patients with ACS admitted to Queen Elizabeth Hospital, Malaysia, from February 2009 till August 2009 were screened prospectively for PVD and AAA. Patients’ data and clinical findings were gathered and analyzed. Measurements of ankle brachial index (ABI) and abdominal aortic diameter were performed by a single assessor. PAD was defined as ABI ≤ 0.9 or diabetic patients with signs and symptoms of PAD and absence of pedal pulses. AAA was defined as abdominal aortic diameter ≥ 3cm. Results: 102 patients were recruited with mean age of 59.5 years old. Male: female ratio was 6:1. 40.2% of patients had NSTEMI; 45.1%, STEMI and 14.7%, unstable angina. Risk factors profile is as follows: hypertension- 68.6%, smoking-56.9%, hypercholesterolemia- 52.9%, diabetes mellitus-35.3% and history of stroke- 5.9%. Median ABI was 1.1 with lowest reading of 0.4. Mean abdominal aortic size was 2.0cm with largest diameter of 3.3cm. PAD was present in 24.5% of patients and AAA in 2.0%. 68.0% of patients with PAD were asymptomatic. Smoking and age more than 60 years were independent predictors for PAD among ACS patients. Conclusions: PAD is strongly correlated with CAD with old age and smoker as independent predictors. However, association between AAA and ACS could not be established.

Objective: To determine the Dermatology Life Quality Index (DLQI) among the subtypes of leprosy and to examine correlation with deformity and lepra reactions. Methods: This was a cross-sectional study done at Dermatology Outpatient Clinic, Queen Elizabeth Hospital and two health clinics in Kota Kinabalu between 1st April 2019 and 30th November 2019. A standardised case report form was formulated to collect the demographic data and disease profile of the leprosy patients. The quality of life (QoL) was assessed using Dermatology Life Quality Index (DLQI) questionnaire. Results: A total of 54 patients were included with a male to female ratio of 2.4:1 (38 males and 16 females). The mean DLQI score was 8.31±6.15. The difference between the mean DLQI scores among the leprosy subtypes was not significant. The most affected domain was symptoms and feeling followed by daily activities and leisure. Twenty-one patients (38.9%) had facial deformity and they were found to have significantly higher DLQI score. WHO grade 1 and 2 disability were observed in 37 patients (68.5%) with higher DLQI score compared to those without any disability. More than half of patients with MB leprosy (52.2%) developed lepra reactions but the difference of mean DLQI scores were not significant. Conclusions: Leprosy-related disabilities may predispose patients to develop psychosocial problems which may have negative impact on QoL. Thus, periodic assessment of QoL should be incorporated into the management of leprosy patients

IntroductionManagement of leprosy in pregnancy is challenging. Here we aim to describe the clinical characteristicsand the management of leprosy in pregnancy.MethodsThis is a retrospective study on pregnant women with leprosy managed in the Department ofDermatology in Hospital Kuala Lumpur, Hospital Pulau Pinang, Hospital Sultanah Bahiyah andHospital Queen Elizabeth between 1994 and 2015.ResultsThere were ten patients with 12 pregnancies with a median age of 27.5 years (range: 16-33). Fivewere foreigners. There were four cases of lepromatous leprosy, two cases of borderline lepromatous,two cases borderline tuberculoid leprosy and one case each for tuberculoid and mid borderline leprosy.Seven pregnancies (58%) were documented to have reactions. Four reversal reactions (33%), threeerythema nodusom leprosum (25%) and two Lucio’s phenomenon (17%) were documented. Bothpatients with Lucio’s phenomenon had undiagnosed leprosy and presented with preterm labour,anemia, oligohydramnios and intrauterine growth restriction. Mortality was recorded in one patientdue to dapsone induced hypersensitivity syndrome complicated with septicaemia. All patients wereprescribed multidrug therapy but in three pregnancies, the patients chose to defer the treatment. Therewas a spontaneous miscarriage at second trimester and a case of early neonatal death. The neonatalcomplications recorded for the 10 live deliveries were low birth weight, jaundice and clofazimineinducedhyperpigmentation.ConclusionThe majority of our patients with leprosy had complications throughout the pregnancies. Earlydetection and prompt treatment can prevent unfavorable fetal outcome & threatened maternal health.
