Hydroxychloroquine for COVID-19: A Single Center, Retrospective Cohort Study

@#Introduction: The outbreak of coronavirus disease (COVID-19) in December 2019 called for a rapid solution, leading to repurposing of existing drugs. Due to its immunomodulatory effect and antiviral properties, hydroxychloroquine (HCQ) has been used in early 2020 for treatment of COVID-19 patients. This study was conducted to evaluate the treatment outcome of HCQ monotherapy in Malaysia. Methods: A retrospective cohort study was conducted in COVID-19 ward in Hospital Kuala Lumpur (HKL), from March to April 2020. A total of 446 COVID-19 patients were recruited, only 325 patients were finally included for analysis. Statistical analysis was done using SPSS, with a significant value set at p<0.05. Results: The mean age of the patients were 38.5 ±15.5. They were majority male, (n=210, 64.6%) Malaysian (n=239, 73.5%) and Malay ethnicity (n=204, 62.8%). Ninety-one (28%) patients received HCQ monotherapy. HCQ monotherapy was associated with worse outcome (OR: 10.29, 95% CI 1.17-90.80). There was a significant difference in mean length of stay between those with and without HCQ treatment (t323=5.868, p<0.001, 95% CI, 2.56-5.31). The average length of stay for HCQ treated group was 3.84 days longer than those without treatment. 6.6% of the patient receiving HCQ monotherapy encountered adverse drug effects. Conclusion: Similar to study reported worldwide, our study demonstrated that HCQ did not improve length of stay and the outcome of COVID-19 patients.

Hypertension in the absence of urinary abnormalities - An unusual presentation of anaphylactoid purpura

@#Henoch-Schonlein Purpura (HSP) or anaphylactoid purpura, currently named IgA vasculitis is the most common form of systemic vasculitis in children. In adults and young infants, HSP tends to have atypical presentations with higher rates of severe gastrointestinal problems and delayed renal complications. While hypertension is a known complication of HSP nephritis, it is rarely seen in individuals with normal renal function and urinary findings. We report a case of a 7-year-old boy with HSP, who presented with abdominal pain and severe hypertension without other features of glomerulonephritis.

The Psychological Impact and Functional Disability of Patients With Acne Vulgaris in Hospital Serdang, Malaysia: A Cross Sectional Analysis

@#Introduction: Acne vulgaris is not only associated with physical morbidity, but also associated with significant psychosocial disturbances, such as depression and suicide. The objective of this study was to examine the functional disability and psychological impact of acne vulgaris. Methods: A cross-sectional study of 55 acne patients, aged more than 12, was conducted in the dermatology clinic of Serdang Hospital from January to March 2017. Data on demographics, clinical features, current treatment modalities were collected. Acne severity was graded using Comprehensive Acne Severity Scale (CASS), Cardiff Acne Disability Index (CADI) was used to assess functional disability, while DASS-21 was used to assess three related states of depression, anxiety and stress. Statistical analysis was done using SPSS software. A p value ≤ 0.05 considered significant. Results: The mean age was 23.2 (14-46), majority were females (39, 70.9%), Malays (44, 80%) and students (34, 61.8%). 53 (96.4%) subjects had almost clear (CASS = 1) to moderate (CASS = 3) acne severity. Majority had facial acne with or without truncal involvement, 53 (96.3%). The average age of disease onset was 17.8 (9-45). 45 (81.8%) patients found their acne mild to moderately disabling. 69.1%, 45.8% and 41.8% reported feeling anxious, depressed and stressed out. CADI was found to be significantly related with depression (p=0.012), anxiety (p= 0.015) and stress (p=0.001). Relationship between CASS with CADI (p=0.07), stress (p=0.09), anxiety (p=0.13) and depression (p=0.12) were insignificant. Conclusion: Although acne vulgaris is not hazardous, it is associated with psychosocial disturbances. Early and effective treatments are necessary, especially when dealing with facial lesions

Pulmonary actinomycosis masquerading as lung cancer: A case report

Pulmonary actinomycosis is a rare yet important and challenging diagnosis to make. It is commonly confused with other lung diseases, such as tuberculosis and bronchogenic carcinoma, leading to delay diagnosis or misdiagnosis. A 49-year-old man presented with a chronic cough, hemoptysis, and pleuritic chest pain. His initial imaging studies including computed tomography (CT) was suggestive of bronchogenic carcinoma. A subsequent CTguided biopsy was consistent with pulmonary actinomycosis and excluded the possibility of bronchogenic carcinoma. He was treated with antibiotic therapy and achieved remission with complete radiological resolution upon follow-up.

Contact sensitisation in adults: a 5-year retrospective review in hospital Kuala Lumpur

Background: The pattern of contact sensitisation should be monitored in order to detect the changing trend of sensitising allergens. We aim to evaluate contact sensitisation in adults suspected to have allergic contact dermatitis. Methods: This is a five-year retrospective review on contact sensitisation in adults patch-tested with the European Standard and extended series between 2011 and 2015 in the Department of Dermatology, Hospital Kuala Lumpur. Results: There were 689 adults (M:F= 1:2.04; mean age 40.5 years) who were patch-tested. The majority (175, 25.4%) were white collar workers and 118 (17.1%) were healthcare workers. The provisional diagnoses of patients included contact dermatitis (80.8%); endogenous eczema (7.9%); hand eczema (3.2%); hand and foot eczema (3.5%); foot eczema (1.4%) and photodermatitis (1.2%). The allergens selected for testing were based on past and present history of exposure. Almost all (688, 99.8%) were patch-tested with the European standard allergens and 466 (67.6%) were tested with the extended series. About three quarter (528, 76.6%) developed at least one positive reaction. The top five most frequent reactions were to nickel sulphate (35.3%); potassium dichromate (16.5%); methylchloroisothiazolinone (12.9%), fragrance mix I (12.6%), and cobalt chloride (10.2%). The commonest sensitisations identified in the extended series were palladium chloride (23/105, 21.9%), stannous chloride (18/85, 21.2%), miconazole (7/44, 15.9%), gold(I)sodium thiosulfate (16/105, 15.2%) and thimerosal (29/202, 14.4%). Conclusion: Contact sensitisation was detected in 76.6% of adults patch-tested. Nickel sulphate was found to be the most frequently sensitising allergen. The rising prevalence of methylchloroisothiazolinone/methylisothiazolinone sensitization poses significant concern.
