Onychomycosis is a common nail disease with numerous etiological pathogens. In order to determine and trend the local mycological pattern of culture-positive diseased nail samples sent from the Department of Dermatology, Hospital Kuala Lumpur, a five-year retrospective audit was carried out, which revealed that non-dermatophyte molds were the predominant fungi isolated, followed by yeasts and dermatophytes. This is similar to two previous studies in Malaysia, but varies greatly from other studies around the world which showed a dermatophyte-predominant prevalence. This could be due to the nature of the environment our patients encountered.
Fulltext Fatal co-infection--melioidosis and leptospirosis

Hin HS, Ramalingam R, Chunn KY, Ahmad N, Ab Rahman J, Mohamed MS

Am J Trop Med Hyg, 2012 Oct;87(4):737-40.

Co-infection of melioidosis and leptospirosis is uncommon. We report here four such cases, confirmed by blood culture for melioidosis and blood polymerase-chain reaction for leptospirosis, which occurred among rescuers involved in a search and rescue operation for a young man who was suspected to have drowned in Lubuk Yu, a recreational forest in Pahang, Malaysia. Despite treatment, three of the patients died from the co-infection.

Fulltext Biocompatible Aloe vera and Tetracycline Hydrochloride Loaded Hybrid Nanofibrous Scaffolds for Skin Tissue Engineering

Ezhilarasu H, Ramalingam R, Dhand C, Lakshminarayanan R, Sadiq A, Gandhimathi C, et al.

Aloe vera (AV) and tetracycline hydrochloride (TCH) exhibit significant properties such as anti-inflammatory, antioxidant and anti-bacterial activities to facilitate skin tissue engineering. The present study aims to develop poly-ε-caprolactone (PCL)/ AV containing curcumin (CUR), and TCH loaded hybrid nanofibrous scaffolds to validate the synergistic effect on the fibroblast proliferation and antimicrobial activity against Gram-positive and Gram-negative bacteria for wound healing. PCL/AV, PCL/CUR, PCL/AV/CUR and PCL/AV/TCH hybrid nanofibrous mats were fabricated using an electrospinning technique and were characterized for surface morphology, the successful incorporation of active compounds, hydrophilicity and the mechanical property of nanofibers. SEM revealed that there was a decrease in the fiber diameter (ranging from 360 to 770 nm) upon the addition of AV, CUR and TCH in PCL nanofibers, which were randomly oriented with bead free morphology. FTIR spectra of various electrospun samples confirmed the successful incorporation of AV, CUR and TCH into the PCL nanofibers. The fabricated nanofibrous scaffolds possessed mechanical properties within the range of human skin. The biocompatibility of electrospun nanofibrous scaffolds were evaluated on primary human dermal fibroblasts (hDF) by MTS assay, CMFDA, Sirius red and F-actin stainings. The results showed that the fabricated PCL/AV/CUR and PCL/AV/TCH nanofibrous scaffolds were non-toxic and had the potential for wound healing applications. The disc diffusion assay confirmed that the electrospun nanofibrous scaffolds possessed antibacterial activity and provided an effective wound dressing for skin tissue engineering.
Clinical characteristics, management, and quality of life of psoriasis patients with coexistent lupus erythematosus: Data from the Malaysian Psoriasis Registry

OBJECTIVE: To describe the clinical characteristics, management and quality of life of psoriasis patients with and without coexistent lupus erythematosus (LE).
METHODS: This retrospective cross-sectional study uses data from the Malaysian Psoriasis Registry (MPR) from January 2007 to December 2018.
RESULTS: Of 21 735 psoriasis patients, 34 (0.16%) had coexistent LE. The male to female ratio among psoriasis patients with coexistent LE was 1:5.8 versus 1.3:1 in patients with psoriasis but without LE. Nearly 70% presented with LE preceding psoriasis. Psoriasis patients with LE had an earlier age of psoriasis onset (27.56 ± 11.51 versus 33.31 ± 16.94 years, P = 0.006), a higher rate of psoriatic arthropathy (26.5% versus 13.0%, P = 0.02), and a significantly greater impairment of quality of life (Dermatology Quality of Life Index >10; 57.6% versus 40.3%, P = 0.04) compared with psoriasis patients without LE. The majority (87.5%) had systemic LE. The incidences of lupus nephritis (72.7% versus 40%) and hematological abnormalities (50% versus 20%) were higher among patients with LE preceding psoriasis compared with those with psoriasis preceding LE. Antinuclear antibody and double-stranded DNA were positive in 59.4% and 28.1% of psoriasis patients with LE, respectively. Hydroxychloroquine triggered the onset of psoriasis in 7 (24.1%) patients. Patients with LE were more likely to receive systemic treatment for psoriasis compared with those without LE (30.3% versus 14.2%, P = 0.008).
CONCLUSIONS: Psoriasis patients with coexistent LE were uncommon, displayed a female preponderance, were more likely to have joint involvement, and had greater quality of life impairment than those without LE. LE preceded psoriasis in most of these patients, and systemic LE was the most common subtype.
