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.

2.The Psychological Impact and Functional Disability of Patients With Acne Vulgaris in Hospital Serdang, Malaysia: A Cross Sectional Analysis
Malaysian Journal of Medicine and Health Sciences 2019;15(2):56-61
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 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.

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.

Abstract
Atopic eczema (AE) is a complex, chronic and recurrent inflammatory pruritic skin condition that
impacts the quality of life and exerts an economic toll on patients and their families. One of the factors
contributing to AE is the immune dysregulation of the Janus kinase-signal transducers and activators
of transcription (JAK-STAT) inflammatory pathway. This has prompted the conduct of various large
clinical trial programs to evaluate the efficacy and safety of Janus kinase inhibitors (JAK-i) for AE.
The overall and significant benefit of these drugs from clinical studies resulted in regulatory approvals
for JAK-i to treat moderate-to-severe atopic eczema. The objective of this position paper was to
evaluate the safety, efficacy and role of upadacitinib, baricitinib and abrocitinib in managing AE and
update the current recommended treatment algorithm within the 2018 Malaysian Clinical Practice
Guidelines for the Management of Atopic Eczema. The Persatuan Dermatologi Malaysia recommends
that these JAK-i can be considered as an option for systemic therapy in severe AE.

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.
