Background: Individuals with AD have an increased susceptibility to colonization with Staphylococcus aureus (S. aureus), contributing to the exacerbation of the disease. Sodium hypochlorite (bleach) has both in vitro and in vivo antimicrobial activity against S.aureus. Objectives: To evaluate the efficacy and safety of diluted sodium hypochlorite (bleach) baths in patients with moderate to severe atopic dermatitis in our Malaysian population. Methods: This was a prospective randomized, investigator-blinded, placebo-controlled study. Patients were randomly assigned through computer generated simple randomized numbers to treatment (bleach baths) or placebo (distilled water baths). Patients were instructed to soak in the baths neck down for 10 minutes, twice a week for 2 months. The efficacy outcome measures were the Eczema Area and Severity Index (EASI) score, percentage body surface area involved, quantitative S. aureus counts and patient’s assessment of overall response (including itch scores). Safety outcomes were also assessed. Results: A total of 36 patients completed the study. EASI scores and body surface area showed significant improvement between treatment and placebo groups at 2 months (p=0.02, p=0.02). At baseline, 88% of patients yielded S. aureus from lesional skin. Although most cultures in the treatment group continued to yield S. aureus, there was a reduction in the density over time, although not statistically significant. Five patients reported burning/stinging and dry skin in the treatment arm which did not differ significantly compared to placebo. Conclusion: Diluted sodium hypochlorite baths as an adjunctive treatment decreased the clinical severity of patients with moderate to severe atopic dermatitis and may reduce S. aureus density. This treatment was well tolerated with minimal adverse effects.

Background & Objective: Symptomatic sarcocystosis has been said to be rare until recent years, when there were reports of outbreaks of febrile myositis for travellers returning from the Malaysian island resorts. In 2012, an outbreak of Sarcocystis nesbitti infection involving 92 college students and staff occurred after returning from Pangkor Island, Malaysia. A few months after recovering from the febrile illness, some patients complained of hair loss. This study aimed to determine the prevalence, clinical features and outcome of this disorder. Methods: All patients who became sick in the outbreak were asked whether they had the hair loss. For those who had, they were interviewed with standard questionnaires, examined and investigated. Patients were followed-up via an online survey 2 years later. Results: Out of 89 patients who were ill, 19 patients (21.4%) complained of alopecia. The mean peak onset was 4 months after the initial illness. Eleven patients (57.9%) reported the hair fall of more than 100 per day. The other symptoms were itch 10 (52.6%), scaling 10 (52.6%), erythema 4 (21.1%), none had scarring. Eleven patients (57.8%) had positive antinuclear factor with high titre (speckled or nucleolar pattern). Two years after the event, 10 had complete or near complete spontaneous recovery, 1 had partial response and 1 had no improvement. Conclusions: A delayed transient diffuse alopecia is seen in close to half of patients with Sarcocystis nesbittiinfection. This high frequency of positive ANF suggested an immune-mediated mechanism.

Syphilis is an ancient sex u a l ly transmitted infection, described since centuries ago, caused by the bacterium Treponema pallidum. Syphilis or luetic disease is known as the great imitator as it can have myriads of clinical presentations, often making it a diagnostic challenge to clinicians. We report a patient with secondary syphilis, wh o presented with scaly plaques on his trunk and face, sparing the palms and soles.

Introduction: Steven-Johnson syndrome and Toxic Epidermal Necrolysis are rare but life threatening severe cutaneous adverse reactions to drugs. To determine the epidemiology of SJS, TEN and SJS/TEN overlap in University Malaya Medical Centre (UMMC). Methods: All patients admitted to UMMC from year 2013-2015 for SJS, SJS/TEN, TEN were recruited. The classification of SJS, SJS/TEN overlap and TEN was made based on the criteria laid down by Bastuji et al.2 Results: A total of 32 patients were recorded to have SJS, SJS/TEN overlap and TEN from 2013 to 2015. Drugs (n=32, 86.49%) remained the most common aetiology of SJS and TEN. The top three commonest drugs are allopurinol (n=6), followed by carbamazepine (n=5) and bactrim (n=3). Conclusion: This study demonstrates that drugs were the most common cause of SJS/TEN. Antibiotics were the most common drug group that caused SJS/TEN. Awareness of the common etiology such as drug is important and high index of suspicion of SJS and TEN is needed if patients were on the above medications.

BACKGROUND: Previous Caucasian studies have described venous thromboembolism in pregnancy; however, little is known about its incidence during pregnancy and early postpartum period in the Chinese population. We investigated the risk of venous thromboembolism in a “real-world” cohort of pregnant Chinese women with no prior history of venous thromboembolism. METHODS: In this observational study, 15,325 pregnancies were identified in 14,162 Chinese women at Queen Mary Hospital, Hong Kong between January 2004 and September 2016. Demographic data, obstetric information, and laboratory and imaging data were retrieved and reviewed. RESULTS: The mean age at pregnancy was 32.4±5.3 years, and the median age was 33 years (interquartile range, 29–36 yr). Pre-existing or newly diagnosed diabetes mellitus was present in 627 women (4.1%); 359 (0.7%) women had pre-existing or newly detected hypertension. There was a small number of women with pre-existing heart disease and/or rheumatic conditions. Most deliveries (86.0%) were normal vaginal; the remaining were Cesarean section 2,146 (14.0%). The incidence of venous thromboembolism was 0.4 per 1,000 pregnancies, of which 83.3% were deep vein thrombosis and 16.7% were pulmonary embolism. In contrast to previous studies, 66.7% of venous thrombosis occurred in the first trimester. CONCLUSION: Chinese women had a substantially lower risk of venous thromboembolism during pregnancy and the postpartum period compared to that of Caucasians. The occurrence of pregnancy-related venous thromboembolism was largely confined to the early pregnancy period, probably related to the adoption of thromboprophylaxis, a lower rate of Cesarean section, and early mobilization.

INTRODUCTION: The impact of noninvasive follicular thyroid neoplasm with papillary-like nuclear features (NIFTP) on the risk of malignancy (ROM) in fine-needle aspiration cytology (FNAC) per The Bethesda System for Reporting Thyroid Cytopathology has not been well reported in Singapore. METHODS: We retrospectively identified 821 thyroid nodules with preoperative FNAC from 788 patients out of 1,279 consecutive thyroidectomies performed between January 2010 and August 2016 in a tertiary general hospital in Singapore. Possible cases of NIFTP were reviewed for reclassification and the impact of NIFTP on ROM was analysed. RESULTS: The incidence of NIFTP was 1.2% (10 out of 821). If NIFTP is considered benign, ROM in Bethesda I through VI were 8.6%, 3.5%, 26.3%, 20.0%, 87.7%, 97.0% versus 8.6%, 4.2%, 28.1%, 26.7%, 89.2% and 100% if NIFTP is considered malignant. Eight patients with NIFTP had follow-up of 15 to 110 months. One had possible rib metastasis as evidenced by I131 uptake but remained free of structural or biochemical disease during a follow-up period of 110 months. None had lymph node metastasis at presentation, nor locoregional or distant recurrence. CONCLUSION Classifying NIFTP as benign decreased ROM in Bethesda II through VI, but the benignity of NIFTP requires more prospective studies to ascertain. The impact of NIFTP on ROM in our institution also appears to be lower than that reported in the Western studies.

Background: Topical corticosteroids are the mainstay of treatment for patients with atopic dermatitis. However, adverse effects associated with long-term steroid use often limit its use. This interventional study compared the efficacy of a proprietary moisturiser containing licochalcone A, omega-6 fatty acids, and ceramide 3 against 1% hydrocortisone cream in treating patients with mild-to-moderate atopic dermatitis. Methods: Patients with mild-to-moderate atopic dermatitis affecting either the cubital fossa or popliteal fossa symmetrically were given twice-daily applications of the moisturiser and hydrocortisone on opposite sides of the body and monitored for a total of three weeks in a non-randomised half body, doubleblind study. Hydrocortisone was switched to aqueous cream after two weeks, whereas the application of the moisturiser continued until study completion. The assessment of SCORing Atopic Dermatitis (SCORAD) index and Dermatology Life Quality index was performed at baseline and every subsequent follow-up visit to measure patients’ response to treatment. Results: The licochalcone A (LA) moisturiser and 1% hydrocortisone (HC) cream both demonstrated significant reduction in sign and symptom scores after only 1 week of treatment (percentage of reduction in sign and symptom scores: 52.8% [LA] vs 58.5% [HC]). Further reduction in mean sign and symptom scores for both treatments was observed at week 2 (61.3% [LA] vs 56.8% [HC]) and also at week 3 when HC was switched to aqueous cream (70.5% [LA] vs 63.5% [HC→aqueous cream]) (p<0.001 vs baseline within the same treatment arm at weeks 1, 2 and 3). When comparing the mean difference in SCORAD index for both individual as well as total skin signs and symptoms between LA and HC (i.e. inter-arm comparison), there was no significant difference between the two treatments for all the assessed parameters. Patients reported improvements in itching, sleeplessness, and overall quality of life over the course of treatment. Conclusion The licochalcone A moisturiser can be considered as an effective steroid-sparing alternative to topical corticosteroids in managing mild-to-moderate atopic dermatitis.

INTRODUCTIONThe aim of this study was to determine the extent to which primary care doctors assessed patients newly diagnosed with hypertension for the risk factors of cardiovascular disease (CVD) during the patients' first clinic visit for hypertension. The study also aimed to examine the trend of assessment for CVD risk factors over a 15-year period.

METHODSThis retrospective study was conducted between January and May 2012. Data was extracted from the paper-based medical records of patients with hypertension using a 1:4 systematic random sampling method. Data collected included CVD risk factors and a history of target organ damage (TOD), which were identified during the patient's first visit to the primary care doctor for hypertension, as well as the results of the physical examinations and investigations performed during the same visit.

RESULTSA total of 1,060 medical records were reviewed. We found that assessment of CVD risk factors during the first clinic visit for hypertension was poor (5.4%-40.8%). Assessments for a history of TOD were found in only 5.8%-11.8% of the records, and documented physical examinations and investigations for the assessment of TOD and secondary hypertension ranged from 0.1%-63.3%. Over time, there was a decreasing trend in the percentage of documented physical examinations performed, but an increasing trend in the percentage of investigations ordered.

CONCLUSIONThere was poor assessment of the patients' CVD risk factors, secondary causes of hypertension and TOD at their first clinic visit for hypertension. The trends observed in the assessment suggest an over-reliance on investigations over clinical examinations.
