Background: Anogenital human papillomavirus (HPV) is the most frequent reported sexually transmitted infection in the world. We aim to describe the local demographic data and the clinical characteristics of anogenital warts (AGWs). Methods: This is a retrospective study on all patients with AGWs who attended the GUM clinic between 2015 and 2020. Data was obtained from case notes and further analysed. Results: A total of 935 patients with AGWs attended the GUM clinic between 2015 and 2020. The mean age was 30.4 years (range 12-84). The male to female ratio was 2.35:1. Majority were Malaysian (97%). Majority of the Malaysian were Malays (61.5%) followed by Chinese (27.7%) and Indian (8.9%). About 5.6% had a history of substance abuse. While the majority (57.9%) were heterosexual, 34.8% were homosexual and 6.4% were bisexual. About 59.8% had more than one sexual partner. A quarter (25.6%) was infected with the human immunodeficiency virus. The most frequent site of AGWs in males was the perianal area (52.6%), followed by the penis (45.7%), and with a fifth of them having lesions at multiple sites. For female patients, the most frequent site of AGWs was the posterior fourchette (45.2%) followed by the labia minora (33%) with 46.6% had involvement at multiple sites. Approximately 17.6% had other concomitant sexually transmitted infections. Local treatment application used included cryotherapy (86.4%), podophyllin (35.3%), tri-chloroacetic acid (26.8%) and imiquimod (2.6%). About 41.5% required combination of these modalities. Nearly 6.2% experienced recurrence. About 2% required surgical intervention. Conclusions AGWs was more commonly observed in male. The most frequent site of involvement was perianal for male (52.6%) and posterior fourchette in female (45.2%).

Summary Staphylococcal toxic shock syndrome (TSS) is a clinical disease with acute onset of fever, rash, hypotension and multi-organ system involvement. Staphylococcal scalded skin syndrome (SSSS), mostly described in neonate and children, is a superficial blistering disease caused by the exfoliative toxin of specific strains of Staphylococcus aureus. TSS and SSSS rarely occur concurrently in adults. We here describe a 35-year-old woman who was initially referred to dermatology team as toxic epidermal necrolysis. She presented with a rapid epidermal detachment without mucosal involvement, fever and shock, associated with acute kidney injury and transaminitis, severe metabolic acidosis, complicated by COVID-19 infection, and finally succumbed within 36 hours of hospitalization. Early recognition and prompt treatment are the key factors in the management as TSS itself can lead to mortality. Staphylococcal TSS and SSSS are important differential diagnosis to consider in acute epidermal detachment, as not all cases are drug-induced.

Antihistamine is standard chronic spontaneous urticaria (CSU) therapy. Weight gain is a side effect of concern as prolonged high dose therapy is common. We investigated the effects of 12-weeks loratadine therapy on weight, appetite and parameters of metabolic syndrome (MetS). A cohort study was performed involving CSU patients aged ≥18 years. Patients with diseases or on drugs affecting weight or appetite were excluded. CSU was treated according to standard management. Weight, height, waist circumference (WC), body mass index (BMI) and blood pressure (BP), Urticaria Activity Score 7 (UAS7), Dermatology Life Quality Index (DLQI), hunger and satiety questionnaire, fasting blood sugar (FBS) and fasting lipid profile (FLP) were obtained at baseline, week 6 and week 12. Loratadine cumulative dose were determined. Thirteen (33.33 %) males and 26 (66.67 %) females aged 33.00 (12.00) years participated. Median weight was 62.55 (18.30) kg, BMI 24.60 (6.80) kg/m2, 13(33.33%) patients had normal weight, 12 (30.77%) overweight, 11 (28.21%) obese and 3 (7.69%) underweight. Significant weight gain was observed at week 6, 67.56 ± 16.14 kg vs 68.16 ± 16.95 kg, p < 0.05 and 67.56 ± 16.14 kg vs 64.73 ± 14.60 kg, p = 0.04 at week 12. Changes in BMI, WC, BP, FBS and FLP were insignificant. Three patients developed MetS. Hunger and satiety scores were unaffected. Loratadine induced weight gain despite no effects on appetite. Weight should be monitored in patients on long term loratadine therapy.

Background: Psoriasis can be a presenting feature of human immunodeficiency virus (HIV) infection. Our objective was to determine the frequency of HIV infection among patients with psoriasis and to describe the clinical features, treatment and quality of life in this population. Methods: This is a multi-centre retrospective cross-sectional study of psoriasis patients who were registered to the Malaysian Psoriasis Registry (MPR) from January 2007 to December 2018. Results: Of a total of 21,735 patients registered, 105 (0.5%) had HIV infection. Among these patients, 90 (85.0%) were male, mean age was 40.90 ± 10.85 years, and plaque psoriasis was the most frequently encountered presentation (85.7%). Significantly more patients with HIV had severe psoriasis (61.3% vs 49.9%, p=0.043), face and neck (62.7% vs 51.4%, p=0.022) involvement, and nail disease (69.9% vs 56.2%, p=0.005) compared to those without HIV. Only n patients (8.7%) had psoriatic arthropathy, and only 9 (8.8%) received systemic therapy, namely acitretin and methotrexate. None received a biologic, and only one patient was treated with narrowband ultraviolet-B therapy. The mean Dermatology Life Quality Index (DLQI) score at enrolment was 10.98 ± 7.07 for the HIV cohort compared to 8.68 ± 6.60 for the non-HIV cohort (t=2.190, p=0.029). More patients with HIV reported a DLQI score >10 compared to those without HIV (51.5% vs 40.2%, p=0.021). Conclusion The frequency of HIV infection among patients with psoriasis in the MPR was 0.5%. Patients with HIV had more severe disease, more nail, face and neck involvement, and greater impairment of quality of life. Treatment of HIV patients with psoriasis remains conservative in Malaysia.

Background: Adolescents, who aged between 10 and 19 years old, comprise about 20% of the world’s population. They are vulnerable to acquisition of sexually transmitted infections (STIs). Here, we aim to determine the demography and pattern of STIs among adolescents attending Genito-Urinary Medicine (GUM) Clinic, Hospital Kuala Lumpur (HKL). Methods: This is a retrospective study on all adolescents attending GUM clinic between 2014 and 2018. Data was obtained from case notes and further analysed. Results: A total of 111 adolescents attended GUM clinic between 2014 and 2018. The mean age was 18 years (range 12-19). The male to female ratio was 2.26:1. All patients were Malaysian. Only 2 were foreign nationals. The majority were Malays (85.3%) followed by Indians (11%) and Chinese (3.7%). About 46.8% were still schooling, 28.8% were employed and 23.4% were unemployed. About 8.3% had a history of substance abuse. The majority (67.6%) were heterosexual, about 17.1% were homosexual and 3.6% were bisexual. Nearly 95% engaged in unprotected sex. Majority (46%) had casual sex. The most frequent presenting symptoms for male and female adolescents were discharge (43.2%) followed by swelling/growth (23.4%). About 83% had confirmed STIs. The most common STIs among the male were gonorrhoea (44.1%), genital warts (23.4%) and non-gonococcal urethritis (14.7%). The most common STIs among the female were herpes genitalis (50%), genital warts (33.3%) and syphilis (8.3%). Six patients were infected with the human immunodeficiency virus (HIV). Conclusion The most common STI among adolescents between 2014 and 2018 was gonorrhoea for male and herpes genitalis for female.

Background: Oral lichen planus is an idiopathic autoimmune inflammatory condition and oral lichenoid reactions are lesions that resemble oral lichen planus clinically and histopathologically, but develop secondary to various underlying causes. Oral lichenoid reactions have been reported to be caused by contact allergy to dental materials. This study aims to describe the characteristics of patients with a clinical and/or histopathological diagnosis of oral lichen planus who underwent patch testing in Hospital Kuala Lumpur, Malaysia. Methods: This is a 5-year retrospective study of patients who had oral lichen planus and had undergone patch testing at the Department of Dermatology, Hospital Kuala Lumpur, Malaysia between January 2015 and Cecember 2019. Patch tests were performed with European Baseline Series and relevant extended series, which include dental and metal series as well as patients’ own products. Patch test results were recorded according to the International Contact Dermatitis Research Group recommendation. Results: There were 41 patients with oral lichen planus who underwent patch test. The median age was 56 (range 21 to 73) with 70.7% of patients being female. There were 29 (70.7%) patients who developed at least one positive reaction. The most frequent sensitizing allergens were nickel sulfate (34.1%), gold(I)sodium thiosulphate dihydrate (22.0%), fragrance mix I (19.5%), cobalt chloride (14.6%), Peru balsam (12.2%) and sodium tetrachloropalladate (II) hydrate (12.2%). Current relevance was recorded in 16 patients (39.0%) and of these patients, 12 of them had positive patch test reactions to allergens found in dental materials such as dental fillings, dental implants, orthodontic braces, dentures and dental crowns. Conclusion Contact sensitization was detected in about 70% of our patients with oral lichen planus. The most common sensitizing allergen was nickel sulfate. Current relevance was found mainly towards dental materials.

Background: Although Dermatology is primarily a non-acute, outpatient-centered clinical specialty, some of them require in-patient care for intensive skin management. We aim to describe the demographic data, clinical characteristics, and outcomes of Dermatology inpatients in Hospital Kuala Lumpur (HKL). Methods: This is a retrospective study on all dermatology inpatients in HKL between 2016 and 2020. Data was obtained from admission records and further analyzed. Results: A total of 1567 patients were admitted to the Dermatology ward between 2016 and 2020 accounted for 2292 admissions. The mean age was 45 years (range 8-93). The male to female ratio was 1.16:1. The majority were Malaysian (99.2%). Most Malaysian were Malays (60%) followed by Chinese (19.3%) and Indian (17.1%). About 91% of the admissions were arranged from the dermatology clinic. The mean length of stay was 5.06 days (range 0-63). About 20% of the patients required multiple admissions. The main dermatological diagnosis requiring inpatient care were non-infective dermatoses (60.4%) which included eczematous dermatoses, autoimmune dermatoses, psoriasis, cutaneous adverse drug reactions, inflammatory and non-inflammatory dermatoses. This was followed by cutaneous infections (24.5%) and drug allergy testing & drug provocation tests (7.9%). About 3% of patients were transferred to other departments for further intensive management, and the rest were discharged home well. No mortality occurred in the Dermatology ward. Conclusion The Dermatology ward HKL managed 2292 admissions between 2016 and 2020. The three main dermatological diagnoses requiring intensive skin management were eczematous conditions, cutaneous infections, and autoimmune dermatoses.

There are geographical, regional, and ethnic differences in the phenotypes and endotypes of patients with drug hypersensitivity reactions (DHRs) in different parts of the world. In Asia, aspects of drug hypersensitivity of regional importance include IgE-mediated allergies and T-cell-mediated reactions, including severe cutaneous adverse reactions (SCARs), to beta-lactam antibiotics, antituberculous drugs, nonsteroidal anti-inflammatory drugs (NSAIDs) and radiocontrast agents. Delabeling of low-risk penicillin allergy using direct oral provocation tests without skin tests have been found to be useful where the drug plausibility of the index reaction is low. Genetic risk associations of relevance to Asia include human leucocyte antigen (HLA)-B*1502 with carbamazepine SCAR, and HLA-B*5801 with allopurinol SCAR in some Asian ethnic groups. There remains a lack of safe and accurate diagnostic tests for antituberculous drug allergy, other than relatively high-risk desensitization regimes to first-line antituberculous therapy. NSAID hypersensitivity is common among both adults and children in Asia, with regional differences in phenotype especially among adults. Low dose aspirin desensitization is an important therapeutic modality in individuals with cross-reactive NSAID hypersensitivity and coronary artery disease following percutaneous coronary intervention. Skin testing allows patients with radiocontrast media hypersensitivity to confirm the suspected agent and test for alternatives, especially when contrasted scans are needed for future monitoring of disease relapse or progression, especially cancers.

Patients with human immunodeficiency virus (HIV) may have significant cutaneous morbidities which can potentially affect their quality of life or be life-threatening. This study aimed to describe the demographic data and the pattern of cutaneous manifestations of patients infected with HIV.

Allergic contact dermatitis affects 15 to 20% of the population. The pattern of contact allergy varies across nations. Therefore, many countries utilize their unique individual baseline series for patch testing. In this study, we aimed to assess the outcome of rubber and fragrance allergy detection with the addition of 1,3-Diphenylguanidine. N-Cyclohexyl-N-Phenyl-4-Phenylenediamine, N-Cyclohexylthiophthalimide and Ylang ylang oil.
