Fulltext Paraneoplastic dermatomyositis: a 12-year retrospective review in the Department of Dermatology Hospital Kuala Lumpur

Tang MM, Thevarajah S

Med J Malaysia, 2010 Jun;65(2):138-42.
PMID: 23756799 MyJurnal

Adult-onset dermatomyositis has been found to be associated with underlying malignancies in up to 40% of patients. The aims of this study were to determine the demographic profile, the underlying cancer and outcome in patients with dermatomyositis. This was a retrospective review of 38 patients with dermatomyositis seen over a 12-year period in the Department of Dermatology, Kuala Lumpur Hospital. Of these, 18 (47.4%) had an associated underlying malignancy. The male to female ratio was 2:1. Ten patients (55.6%) were Chinese. The youngest patient encountered was 32 years old. Nasopharyngeal carcinoma (61.1%) was the most common malignancy in our study population. Tumour markers were not useful as the initial screening for malignancies. Thorough screening for malignancy is imperative in adult dermatomyositis especially those above 40 years old.
Fulltext Dapsone syndrome--first Malaysian paediatric case report

Zurina Z, Elizawaty O, Thevarajah S, Norlijah O

Med J Malaysia, 2012 Feb;67(1):105-7.
PMID: 22582558

Dapsone syndrome is a potentially fatal hypersensitivity reaction to sulphone. We report a 12-year-old girl who developed high grade fever associated with intense jaundice, exfoliative skin rash and hepatomegaly after five weeks of starting the multidrug regimen for the treatment of Hansen's disease. Laboratory investigations revealed presence of leucocytosis with eosinophilia, deranged liver enzymes and an abnormal coagulation profile. Immediate cessation of the offending drug and administration of steroid proved successful. A high level of clinical awareness is fundamental for early diagnosis of dapsone syndrome as initiation of a prompt treatment may lead to rapid recovery.
Penicillium marneffei infection in an African man

Yap FB, Thevarajah S, Asmah J

Dermatol. Online J., 2010;16(7):2.
PMID: 20673530

Penicilliosis is a systemic fungal infection caused by Penicillium marneffei. The infection is most commonly seen in Southeast Asia, Southern China, Hong Kong, and Taiwan. It is rarely seen among individuals of African descent. Here, we report a case of penicilliosis in an African man from Namibia who was studying in Malaysia. He presented with multiple umbilicated papules associated with cough, fever, loss of appetite, and weight. He also had urethral discharge and admitted to unprotected sexual intercourse with multiple partners. Histopathological examination of a skin papule showed the presence of multiple 2 to 4 microm intracellular yeast cells. Culture of the papule revealed Penicillium marneffei. The serology for human immunodeficiency virus (HIV) was positive. This case illustrates the need to recognize penicilliosis in any individuals staying or travelling to Southeast Asia and the need to look for underlying HIV infection in adults with umbilicated papules.
Invasive squamous cell carcinoma arising from chromoblastomycosis

Jamil A, Lee YY, Thevarajah S

Med Mycol, 2012 Jan;50(1):99-102.
PMID: 21449695 DOI: 10.3109/13693786.2011.571295

Chromoblastomycosis is a chronic subcutaneous mycosis seen mainly in tropical regions. While malignant transformation rarely occurs, the present report describes a 69-year-old man with a 21-year history of chromoblastomycosis complicated by invasive squamous cell carcinoma requiring amputation of the affected limb. A review of previous reported cases shows malignancy arising after 20-30 years of infection in ≥60-year-old males who have received inadequate treatment of chromoblastomycosis and have had relapses. An immunocompromised state is not an associated feature of such cases. The extremities are commonly affected as carcinomas occur from the most chronic lesions which are generally found on these limbs.

Fulltext Anaesthetic challenges in a patient with Wolff-Parkinson-White (WPW) syndrome for orchidectomy

Yeap TB, Teah MK, Thevarajah S, Azerai S

BMJ Case Rep, 2021 Mar 25;14(3).
PMID: 33766970 DOI: 10.1136/bcr-2020-241176

Wolff-Parkinson-White (WPW) syndrome is an extremely rare congenital cardiac conduction disorder. It is due to an aberrant pathway between the atrium and ventricle. This manuscript entails a man with an underlying WPW who was posted for an elective orchidectomy. We discussed the important perioperative precautions to prevent the precipitation of acute cardiac events.
Fulltext Case report: A rare occurrence of a huge mediastinal mass from disseminated prostate carcinoma

Teah KM, Bong CP, Mudin K, Soe MZ, Thevarajah S, Yeap BT

Ann Med Surg (Lond), 2021 Nov;71:102952.
PMID: 34703592 DOI: 10.1016/j.amsu.2021.102952

Background: Prostatic carcinoma is the commonest malignancy among men. It usually metastasizes to the spine and regional lymph nodes. However, it is extremely rare for it to metastasize to the mediastinum.
Case presentation: An elderly man presented to us with progressive onset of bilateral lower limb weakness which was associated with thoracic radiculopathy and urinary incontinence. An urgent magnetic resonance imaging (MRI) of the spine showed severe cord compression with enlarged prostate and superior mediastinal mass. A computed tomography (CT) guided biopsy of the mediastinal mass was suggestive of prostatic malignancy. An emergency posterior instrumentation and fusion (PSIF) in prone position was successfully done. Histopathological examination of the spine showed malignant glandular tissues, suggestive of prostate.
Discussion: A huge mediastinal mass can compromise the cardiorespiratory system and is very challenging for the anaesthetist to safely secure the airway for surgical procedures. Androgen deprivation therapy (ADT) for patients with metastatic prostatic carcinoma can be achieved either by medical castration or with bilateral orchidectomy.
Conclusion: It is extremely uncommon for a prostatic carcinoma to metastasize to the mediastinum. Patients with a huge mediastinal mass possess risks of cardiorespiratory collapse perioperatively. Chemoradiotherapy and androgen deprivation therapy (ADT) can be utilized for metastatic prostatic carcinoma with good outcomes.
Fulltext Asian consensus on assessment and management of mild to moderate plaque psoriasis with topical therapy

Imafuku S, Zheng M, Tada Y, Zhang X, Theng C, Thevarajah S, et al.

J Dermatol, 2018 Jul;45(7):805-811.
PMID: 29740870 DOI: 10.1111/1346-8138.14338

A working group of dermatologists in Asian countries assessed the current status of psoriatic management in the region to prepare a consensus report on topical treatment in mild to moderate plaque psoriasis. Even though the association of psoriasis with systemic comorbidities is increasingly acknowledged, psoriasis is still lower in health-care priority lists in the region. The psychosocial impact of psoriasis may be greater in Asian countries due to cultural norms and social discrimination. Non-adherence to treatment is also common among Asians. The current care given to patients with mild to moderate psoriasis needs to be streamlined, enhanced and organized with a patient-centered care approach to achieve better outcomes. A comprehensive assessment of the disease severity and its impact on a patient's life is required before initiating treatment. Education and active involvement of the patient in the treatment plan is an important part of psoriatic management. It is recommended to personalize topical treatment to meet the needs of the patient, depending on disease severity, psychosocial impact, the patient's expectations and, more importantly, the patient's willingness and ability to actively follow the treatment procedure. Fixed-dose combination of corticosteroid and vitamin D analogs is the preferred topical medication for both initial and maintenance phases of treatment. The fast containment of the disease is the goal of the initial phase of 4-8 weeks and it demands a potent fast-acting topical therapy. Satisfactory control of the disease and prevention of relapses should be achieved during the maintenance phase with twice a week or weekend applications.
Fulltext A rare occurrence of a metastatic urothelial carcinoma to the thoracic vertebra: A case report

Soe MZ, Bong CP, Thevarajah S, Teah KM, Yeap BT

Ann Med Surg (Lond), 2022 Feb;74:103297.
PMID: 35127072 DOI: 10.1016/j.amsu.2022.103297

Background: Urothelial carcinoma (UC) is a common urinary tract malignancy that predominantly affect the urinary bladder with a low recurrence rate after surgical removal. It usually metastasizes to the lungs, regional lymph nodes, and liver. However, it rarely spread to the thoracic spine and bones, especially in the Asian populations.
Case presentation: A 50-years-old Asian man, with a one-year history of surgically resected UC, presented to us with a complaint of worsening upper back pain for three months. Magnetic resonance imaging (MRI) showed a destructed second thoracic (T2) vertebra with lytic lesion. A thoracic vertebrectomy was performed and histopathological examination (HPE) showed high-grade infiltrating metastatic malignant UC. Postoperatively, he was well and did not have any back pain. He was followed up under combined spine and oncology clinic regularly and was planned for chemoradiotherapy.
Discussion: UC commonly metastasizes to the lungs, liver, and lymph nodes. In young Asians, thoracic spinal metastases are rare. Urgent palliative spinal surgery is indicated to prevent further deterioration of function. Intraoperative usage of targeted controlled infusion (TCI) of remifentanil and propofol as maintenance of anaesthesia are gold standard in assisting spine surgeons who are guided by neuromuscular monitoring.
Conclusion: Spinal metastasis to the thoracic vertebra is rare among young Asian men. Patients presented with acute neurological deficits and back pain are indicated for spinal surgery. Multidisciplinary approach is needed for management of patients with spinal metastasis. Targeted controlled infusion (TCI) of remifentanil and propofol are gold standard for maintenance of anaesthesia for spine surgeries which are guided by somatosensory, and motor evoked potential monitoring.
Nasal carriers are more likely to acquire exogenous Staphylococcus aureus strains than non-carriers

Ghasemzadeh-Moghaddam H, Neela V, van Wamel W, Hamat RA, Shamsudin MN, Hussin NS, et al.

Clin Microbiol Infect, 2015 Nov;21(11):998.e1-7.
PMID: 26183299 DOI: 10.1016/j.cmi.2015.07.006

We performed a prospective observational study in a clinical setting to test the hypothesis that prior colonization by a Staphylococcus aureus strain would protect, by colonization interference or other processes, against de novo colonization and, hence, possible endo-infections by newly acquired S. aureus strains. Three hundred and six patients hospitalized for >7 days were enrolled. For every patient, four nasal swabs (days 1, 3, 5, and 7) were taken, and patients were identified as carriers when a positive nasal culture for S. aureus was obtained on day 1 of hospitalization. For all patients who acquired methicillin-resistant S. aureus (MRSA) or methicillin-susceptible S. aureus via colonization and/or infection during hospitalization, strains were collected. We note that our study may suffer from false-negative cultures, local problems with infection control and hospital hygiene, or staphylococcal carriage at alternative anatomical sites. Among all patients, 22% were prior carriers of S. aureus, including 1.9% whom carried MRSA upon admission. The overall nasal staphylococcal carriage rate among dermatology patients was significantly higher than that among neurosurgery patients (n = 25 (55.5%) vs. n = 42 (16.1%), p 0.005). This conclusion held when the carriage definition included individuals who were nasal culture positive on day 1 and day 3 of hospitalization (p 0.0001). All MRSA carriers were dermatology patients. There was significantly less S. aureus acquisition among non-carriers than among carriers during hospitalization (p 0.005). The mean number of days spent in the hospital before experiencing MRSA acquisition in nasal carriers was 5.1, which was significantly lower than the score among non-carriers (22 days, p 0.012). In conclusion, we found that nasal carriage of S. aureus predisposes to rather than protects against staphylococcal acquisition in the nose, thereby refuting our null hypothesis.
Fulltext Socioeconomic and sociocultural determinants of psychological distress and quality of life among patients with psoriasis in a selected multi-ethnic Malaysian population

Kwan Z, Bong YB, Tan LL, Lim SX, Yong AS, Ch'ng CC, et al.

Psychol Health Med, 2017 02;22(2):184-195.
PMID: 27541601 DOI: 10.1080/13548506.2016.1220603

Patients with psoriasis may have increased risk of psychological comorbidities. This cross-sectional study aimed at determining associations between sociocultural and socioeconomic factors with the Depression Anxiety Stress Scale (DASS) scores and the Dermatology Life Quality Index (DLQI) scores. Adult patients with psoriasis were recruited from a Dermatology outpatient clinic via convenience sampling. Interviews were conducted regarding socio-demographic factors and willing subjects were requested to complete the DASS and DLQI questionnaires. The Pearson χ2 test, Fisher's exact test and multivariate logistic regression were used for statistical analysis to determine independent predictors of depression, anxiety, stress and severe impairment of quality of life. Unadjusted analysis revealed that depression was associated with Indian ethnicity (p = .041) and severe impairment of quality of life was associated with Indian ethnicity (p = .032), higher education (p = .013), higher income (p = .042), and employment status (p = .014). Multivariate analysis revealed that Indian ethnicity was a predictor of depression (p = .024). For stress, tertiary level of education (p = .020) was an independent risk factor while a higher monthly income was a protective factor (p = .042). The ethnic Indians and Malays were significantly more likely than the ethnic Chinese to suffer reduced quality of life (p = .001 and p = .006 respectively) and subjects with tertiary education were more likely to have severe impairment of quality of life (p = .002). Our study was unique in determining sociocultural influences on psychological complications of psoriasis in a South East Asian population. This has provided invaluable insight into factors predictive of adverse effects of psoriasis on psychological distress and quality of life in our patient population. Future studies should devise interventions to specifically target at risk groups in the development of strategies to reduce morbidity associated with psoriasis.

Correlation of whole blood hydroxychloroquine concentration with cutaneous lupus erythematosus and factors associated with it: First multicenter, cross-sectional analysis in Malaysia

Peh D, Wan Ahmad Kammal WSL, Beh PJ, Yong ACH, Tan WC, Lim AL, et al.

J Dermatol, 2022 Jan 24.
PMID: 35067938 DOI: 10.1111/1346-8138.16292

Hydroxychloroquine (HCQ) is the first-line systemic treatment for cutaneous lupus erythematosus (CLE). Whole blood HCQ concentration (WBHCQ) was found to correlate with CLE severity among Caucasians. However, studies on Asians are scarce. We aim to explore the relationship of WBHCQ with CLE disease activity among multi-racial Malaysians and the factors associated with WBHCQ. A cross-sectional study targeting patients with CLE was conducted from 1 June till 30 November 2019. Disease activity was assessed using Cutaneous Lupus Erythematosus Disease Area and Severity Index - Activity Score (CLASI-AS). Blood was analyzed for WBHCQ concentration using a high-performance liquid chromatography technique. Statistical analysis was done using R studio version 1.2.1335. A total of 88 subjects (male : female, 4.5:1) with a median age of 41 years old were recruited. The median duration CLE was 5 years. The majority had acute cutaneous lupus (n = 45, 51.1%). The median WBHCQ was 946.8 ng/mL. Indians were found to have the highest WBHCQ (median ± interquartile range [IQR], 1515.4 ± 1494.8 ng/mL). Males had a lower WBHCQ (median ± IQR, 733.5 ± 573.8 ng/mL) than females (995.5 ± 925.1 ng/mL). However, no statistically significant association between race and sex with WBHCQ was demonstrable (p = 0.247, p = 0.066). No correlation was demonstrated between WBHCQ and CLASI-AS (r = -0.02, p = 0.851). A positive correlation was found between HCQ dosage (ideal bodyweight) and WBHCQ (r = 0.24, p = 0.027). No other factors were found associated with WBHCQ. Indians and females were observed to have higher WBCHQ; however, no significant correlation was identified. Further study is required to confirm the finding.
Fulltext Position Statement on Secukinumab in the Management of Plaque Psoriasis: The Malaysian Perspective

Johar A, Thevarajah S, Heng A, Chan LC, Ch'ng CC, Mohd Safdar NA, et al.

Dermatol Res Pract, 2019;2019:8923168.
PMID: 31214257 DOI: 10.1155/2019/8923168

Psoriasis is a chronic inflammatory skin disease affecting nearly 10% of dermatologic patients in Malaysia. Treatment options include topical agents and phototherapy as well as nonbiologic and biologic systemic therapy. Mild psoriasis can often be managed with topical agents. However, managing moderate to severe psoriasis is more challenging and may require systemic treatment with nonbiologics or biologics. Despite the availability of several biologics, there are many unmet clinical needs, which may be addressed by secukinumab, an IL-17A inhibitor. This position statement is based on an expert panel discussion and is intended to provide dermatologists an overview of existing options as well as to provide a better understanding of secukinumab and how it can be integrated into current practice. During the discussion, panel members examined current approaches and the role of secukinumab in plaque psoriasis management. Panel members estimated that up to 30% of patients have moderate to severe psoriasis but only 1-2% receive biologics. Highlights from the discussion were that (i) the threshold for biologic use should be lower, in line with international guidelines; (ii) studies have shown that secukinumab has several advantages over other biologics which are greater efficacy, sustained efficacy over time, rapid onset of action, and early evidence of possible disease-modifying potential; and (iii) ideal candidates for secukinumab are all patients of moderate to severe psoriasis, including those with history of treatment failure, difficult-to-treat patterns of psoriasis (nail, scalp, and palmoplantar psoriasis), psoriatic arthritis, and comorbidities and those aiming for clear skin. Panel members recommend that secukinumab be considered first line option among biologic therapies.
Fulltext Modified J-CAPRA scoring system in predicting treatment outcomes of metastatic prostate cancer patients undergoing androgen deprivation therapy

Lim J, Hinotsu S, Onozawa M, Malek R, Sundram M, Teh GC, et al.

Cancer Med, 2020 12;9(24):9346-9352.
PMID: 33098372 DOI: 10.1002/cam4.3548

The J-CAPRA score is an assessment tool which stratifies risk and predicts outcome of primary androgen deprivation therapy (ADT) using prostate-specific antigen, Gleason score, and clinical TNM staging. Here, we aimed to assess the generalisability of this tool in multi-ethnic Asians. Performance of J-CAPRA was evaluated in 782 Malaysian and 16,946 Japanese patients undergoing ADT from the Malaysian Study Group of Prostate Cancer (M-CaP) and Japan Study Group of Prostate Cancer (J-CaP) databases, respectively. Using the original J-CAPRA, 69.6% metastatic (M1) cases without T and/or N staging were stratified as intermediate-risk disease in the M-CaP database. To address this, we first omitted clinical T and N stage variables, and calculated the score on a 0-8 scale in the modified J-CAPRA scoring system for M1 patients. Notably, treatment decisions of M1 cases were not directly affected by both T and N staging. The J-CAPRA score threshold was adjusted for intermediate (modified J-CAPRA score 3-5) and high-risk (modified J-CAPRA score ≥6) groups in M1 patients. Using J-CaP database, validation analysis showed that overall survival, prostate cancer-specific survival, and progression-free survival of modified intermediate and high-risk groups were comparable to those of original J-CAPRA (p > 0.05) with Cohen's coefficient of 0.65. Around 88% M1 cases from M-CaP database were reclassified into high-risk category. Modified J-CAPRA scoring system is instrumental in risk assessment and treatment outcome prediction for M1 patients without T and/or N staging.
Fulltext Dermatology Life Quality Index in Patients with Psoriasis Treated with Biologic Versus Non-biologic Treatment in Malaysia: A Retrospective Cross-Sectional Study

Robinson S, Moon TM, Eng TK, Yuen TT, Jong TJ, Selvarajah L, et al.

Drugs Real World Outcomes, 2023 Jun;10(2):291-298.
PMID: 36840826 DOI: 10.1007/s40801-023-00359-1

BACKGROUND: Psoriasis imposes a substantial burden on patients' social, emotional, physical, and family life. Although psoriasis has no complete cure, various treatments are available to control its symptoms and improve a patients' quality of life.
OBJECTIVE: We aimed to compare the effectiveness of biologic versus non-biologic treatments on health-related quality of life among patients with psoriasis in Malaysia.
METHODS: This retrospective cross-sectional study evaluated data of adult patients diagnosed with psoriasis during 2007-18 from the Malaysian Psoriasis Registry. Baseline demographics, disease, and treatment characteristics were described. For a subset of patients treated with biologics and non-biologics who had baseline and 6-month follow-up data available, changes in the mean Dermatology Life Quality Index scores and the proportion of patients with a clinically relevant improvement (≥ 4 points) post-treatment were assessed.
RESULTS: Overall, 15,238 adult patients with psoriasis from the Malaysian Psoriasis Registry were included in the analysis. Patients receiving biologics showed a statistically significant reduction in the mean Dermatology Life Quality Index scores after 6 months compared with those receiving non-biologic treatment (- 5.7 vs - 0.8%; p < 0.001). The proportion of patients who achieved a ≥ 4-point improvement in Dermatology Life Quality Index scores was approximately two times greater in the biologic-treated group versus the non-biologic-treated group (56.4 vs 27.7%).
CONCLUSIONS: Biologic treatment showed a greater reduction in the Dermatology Life Quality Index scores of patients with psoriasis versus non-biologic treatment. These results highlight the importance of early treatment with more efficacious treatment options, such as biologic therapies, to improve the overall health-related quality of life of patients with psoriasis.
Fulltext Clinical outcomes of abiraterone acetate and predictors of its treatment duration in metastatic castration-resistant prostate cancer: Real-world experience in the Southeast Asian cohort

Lim J, Amantakul A, Shariff N, Lojanapiwat B, Alip A, Ong TA, et al.

PMID: 32374087 DOI: 10.1002/cam4.3101

It is of much interest to understand the efficacy of abiraterone acetate (AA) in routine clinical practice. We assessed the clinical outcome of AA in patients with metastatic castration-resistant prostate cancer (mCRPC) and determined clinical factors associated with AA treatment duration in real-world setting. This real-world cohort consisted of 93 patients with mCRPC treated with AA in Thailand (58.1%) and Malaysia (41.9%). Primary endpoints were overall survival (OS) and biochemical progression-free survival (bPFS). Secondary endpoints were predictors associated with AA treatment duration evaluated with Cox proportional hazards regression. Around 74% were chemotherapy-naïve. The median AA treatment duration was 10 months (IQR 5.6-17.1). Malaysians had a relatively lower median OS and bPFS (OS 17.8 months; 95% CI 6.4-29.1, bPFS 10.4 months; 95% CI 8.8-12.0) compared to Thais (OS 27.0 months; 95% CI 11.3-42.7, bPFS 14.0 months; 95% CI 5.8-22.2), although it did not achieve statistical significance (P > .05). Patients with longer AA treatment duration (>10 months) had lower risk of death and longer bPFS, compared to those with shorter AA treatment duration (≤10 months) (hazard ratio [HR] 0.10, 95% CI 0.05-0.22 and HR 0.13, 95% CI 0.06-0.25, respectively). Multivariable analysis showed that PSA at AA initiation, presence of PSA response and chemotherapy-naive were independently associated with AA duration (P

Fulltext Pimecrolimus for the Treatment of Atopic Dermatitis in Infants: An Asian Perspective

Chu CY, Yao TC, Shih IH, Yang CY, Chin CL, Ibrahim SBBK, et al.

Dermatol Ther (Heidelb), 2023 Mar;13(3):717-727.
PMID: 36735214 DOI: 10.1007/s13555-022-00886-9

Atopic dermatitis (AD) is a common chronic, multisystem inflammatory skin disease in pediatric patients. There has been an increase in the incidence of AD in the pediatric population of the Asia-Pacific region. Studies have shown that genetic, epigenetic, environmental and cultural factors may lead to differences in the clinical manifestation and prevalence of AD between races. Early treatment of AD is necessary to prevent the atopic march leading to comorbidities such as asthma and allergic rhinitis. Topical corticosteroids (TCS) are used as first-line therapy for the treatment of AD, but their long-term usage poses a risk to the patient's health. Pimecrolimus (1%) is a topical calcineurin inhibitor (TCI) that is indicated for the treatment of mild to moderate AD. Pimecrolimus has no apparent increase in adverse events compared to TCS, and it causes less of a burning sensation than tacrolimus. The safety and efficacy of pimecrolimus has been established through various clinical trials; yet, in many Asian countries, the use of pimecrolimus in infants is still restricted due to safety concerns. Based on the available evidence, the expert panel recommends pimecrolimus in infants between 3 months and 2 years of age in the Asian population.
