    PMID: 12650596
    A total of 576 dermatophytes were isolated from patients with a variety of skin infections from January 1993 to May 2000. Ten species of dermatophytes were identified: Epidermophyton floccosum (0.7%), Microsporum audouinii (1.1%), M. canis (3.1%), M. gypseum (0.3%), Trichophyton concentricum (3.5%), T. equinum (0.2%), T. mentagrophytes (36.1%), T. rubrum (53.8%), T. verrucosum (0.2) and T. violaceum (1.0%). The body sites most frequently affected by dermatophytes were the buttocks, nails and trunk. Anthropophilic dermatophytes made up 60.1% of the isolates; the most common species was T. rubrum, T. mentagrophytes and M. canis were the two main zoophilic dermatophytes. T. mentagrophytes was isolated from all body sites except the scalp. M. canis was found to be associated with domestic dogs and was not isolated from ethnic Malays. The only geophilic dermatophyte was M. gypseum, an uncommon dermatophyte associated with tinea pedis.

    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.

    PMID: 33669627 DOI: 10.3390/molecules26041093
    Essential oils (EOs) are known to have varying degrees of antimicrobial properties that are mainly due to the presence of bioactive compounds. These include antiviral, nematicidal, antifungal, insecticidal and antioxidant properties. This review highlights the potential of EOs and their compounds for application as antifungal agents for the treatment of skin diseases via conventional and nonconventional approaches. A search was conducted using three databases (Scopus, Web of Science, Google Scholar), and all relevant articles from the period of 2010-2020 that are freely available in English were extracted. In our findings, EOs with a high percentage of monoterpenes showed strong ability as potential antifungal agents. Lavandula sp., Salvia sp., Thymus sp., Citrus sp., and Cymbopogon sp. were among the various species found to show excellent antifungal properties against various skin diseases. Some researchers developed advanced formulations such as gel, semi-solid, and ointment bases to further evaluate the effectiveness of EOs as antifungal agents. To date, most studies on the application of EOs as antifungal agents were performed using in vitro techniques, and only a limited number pursued in vivo and intervention-based research.

  4. Fulltext Phialophora richardsiae isolated from a cutaneous lesion
    Suppiah M, Chin CS, Keah KC
    Med J Malaysia, 1987 Dec;42(4):306-8.
    PMID: 3454404
    Human infections due to Phialophora richardsiae, first described in 1968, is usually associated with subcutaneous cysts, although there have been reported cases of ulcerative lesions with discharging sinuses as well as infection of bones and tendon sheaths.1,2,3 Because infections by P.richardsiae are rare and the fungus relatively unknown in Malaysia, it was thought worthwhile to report the isolation of this fungus from a cutaneous lesion.

  7. Skin and subcutaneous infections in south-east Asia
    Nor NM, Baseri MM
    Curr. Opin. Infect. Dis., 2015 Apr;28(2):133-8.
    PMID: 25706913 DOI: 10.1097/QCO.0000000000000150
    We reviewed current literature on four different skin and subcutaneous infections which are often touted as 'emerging diseases' of south-east Asia, namely melioidosis, penicilliosis, sporotrichosis and Mycobacterium marinum infection. Lack of consensus treatment guidelines, high treatment costs and limited investigative capability in certain endemic areas are among the challenges faced by managing physicians. With the increase in borderless travelling, it is hoped that this review will facilitate better understanding and heighten the clinical suspicion of such infections for clinicians in other parts of the world.

  8. In Vitro Antifungal Susceptibility of Neoscytalidium dimidiatum Clinical Isolates from Malaysia
    James JE, Santhanam J, Lee MC, Wong CX, Sabaratnam P, Yusoff H, et al.
    Mycopathologia, 2017 Apr;182(3-4):305-313.
    PMID: 27815659 DOI: 10.1007/s11046-016-0085-5
    Neoscytalidium dimidiatum is an opportunistic fungus causing cutaneous infections mostly, which are difficult to treat due to antifungal resistance. In Malaysia, N. dimidiatum is associated with skin and nail infections, especially in the elderly. These infections may be mistaken for dermatophyte infections due to similar clinical appearance. In this study, Neoscytalidium isolates from cutaneous specimens, identified using morphological and molecular methods (28 Neoscytalidium dimidiatum and 1 Neoscytalidium sp.), were evaluated for susceptibility towards antifungal agents using the CLSI broth microdilution (M38-A2) and Etest methods. Amphotericin B, voriconazole, miconazole and clotrimazole showed high in vitro activity against all isolates with MIC ranging from 0.0313 to 1 µg/mL. Susceptibility towards fluconazole and itraconazole was noted in up to 10% of isolates, while ketoconazole was inactive against all isolates. Clinical breakpoints for antifungal drugs are not yet available for most filamentous fungi, including Neoscytalidium species. However, the results indicate that clinical isolates of N. dimidiatum in Malaysia were sensitive towards miconazole, clotrimazole, voriconazole and amphotericin B, in vitro.

    A 2-year-old, exotic shorthair cat presented with baldness and mild scaling on trunk that was confirmed as Microsporum canis (M. canis) infection by the following methods. Wood's lamp and trichogram were used to demonstrate fungal elements suggestive of dermatophytosis consistent with M. canis. Dermatophyte test medium (DTM) and polymerase chain reaction (PCR) were used for identification. E-test and broth microdilution test were then utilized to estimate antifungal minimal inhibitory concentrations (MICs) towards ITZ and TRF respectively. The strain was isolated from the patient and revealed TRF MIC >32 µg/ml and ITZ MIC 0.023 µg/ml. Patient was cured of dermatophytosis with systemic ITZ.

    PMID: 16196378
    An in-house prepared M. furfur antigen was used to carry out a seroprevalence study in an urban population in Malaysia by indirect immunofluorescence assay. Of the 800 serum samples from all ages screened, 738 samples were positive for M. furfur specific IgG, giving an overall seropositive rate of 92.3%. There was no significant difference in the seropositive rates among the different gender group and races. However, there was a statistical significant difference in the seropositive rate among different age groups with a lower rate (73%) for the age group 5 years old and below, which increased rapidly to 99% for the 16 to 20 years old age group but declined slightly for the oldest age group. The degree of seropositivity, which semi-quantitatively reflect the anti-M. furfur specific IgG titre, did not show any significant difference among the gender and racial groups. On the other hand, there was a significant difference in the degree of seropositivity among the various age groups, with the 16 to 20 years old age group having the highest antibody titre and the extreme of age groups having the lower antibody titre.

  12. Prevalence and associated factors for isolated Malassezia species in patients with Dandruff in Mekelle City, Tigrai, Ethiopia
    Gebrezihier BG, Abdulkadir M, Sbhatu DB, Tsegay E, Berhe GG
    BMC Res Notes, 2024 Nov 12;17(1):336.
    PMID: 39533436 DOI: 10.1186/s13104-024-06998-z
    OBJECTIVE: Dandruff, a condition caused by lipophilic Malassezia fungi, is an excessive shed of dead skin cells from the scalp. Effective preventive and curative measures of the condition depend on knowledge and understanding of the prevalence of the condition, the common etiologic species, and the associated factors. This study aimed to investigate the prevalence, common etiologic species, and associated factors of Malassezia infection in Mekelle City, Ethiopia.

    METHOD: A facility-based cross-sectional study was conducted from February 2019 to June 2020 involving 217 participants who were visiting dermatology clinics to seek treatment for dandruff conditions. Information on the socio-demographic characteristics and hair care behaviors of the participants was obtained. Isolation and identification of Malassezia species from scalp scrapings using cultural and biochemical tests were carried out.

    RESULTS: Out of the 217 participants with dandruff, 111 (51.15%) were positive for Malassezia fungi. One hundred forty (140) Malassezia isolates were collected from the 111 positive participants. Further study of the isolates yielded three etiologic species: Malassezia globosa (67.15%), M. furfur (21.70%), and M. restricta (12.15%). Demographic characteristics, namely gender (AOR = 2.605; 95%CI: 1.427 - 4.757) and age (AOR = 2.667; 95%CI: 1.046 - 6.795), as well as hair care behaviors, namely use of hair oil (AOR = 2.964; 95%CI: 1.288 - 6.820), were associated with the presence of Malassezia species. However, the use of anti-dandruff shampoo (AOR = 2.782; 95%CI: 1.301 - 10.993) was negatively associated with the presence of Malassezia species among the participants with dandruff conditions. These findings open opportunities to devise effective prevention, management, and control measures for Malassezia-based dandruff conditions.

    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.

    Trichosporon species are opportunistic yeasts which can cause infections, especially in immunocompromised patients. This is a report of Trichosporon ovoides that caused subcutaneous infection in a patient with underlying ischemic heart disease. The identification of fungal isolate was confirmed by PCR sequencing of ITS and large subunit regions in rRNA gene. In vitro susceptibility study showed that the isolate was susceptible to amphotericin B, fluconazole and voriconazole, and resistant to caspofungin, anidulafungin and itraconazole. The lesion improved after treatment with oral fluconazole and topical miconazole.

  17. Invasive aspergillosis in developing countries
    Chakrabarti A, Chatterjee SS, Das A, Shivaprakash MR
    Med Mycol, 2011 Apr;49 Suppl 1:S35-47.
    PMID: 20718613 DOI: 10.3109/13693786.2010.505206
    To review invasive aspergillosis (IA) in developing countries, we included those countries, which are mentioned in the document of the International Monetary Fund (IMF), called the Emerging and Developing Economies List, 2009. A PubMed/Medline literature search was performed for studies concerning IA reported during 1970 through March 2010 from these countries. IA is an important cause of morbidity and mortality of hospitalized patients of developing countries, though the exact frequency of the disease is not known due to inadequate reporting and facilities to diagnose. Only a handful of centers from India, China, Thailand, Pakistan, Bangladesh, Sri Lanka, Malaysia, Iran, Iraq, Saudi Arabia, Egypt, Sudan, South Africa, Turkey, Hungary, Brazil, Chile, Colombia, and Argentina had reported case series of IA. As sub-optimum hospital care practice, hospital renovation work in the vicinity of immunocompromised patients, overuse or misuse of steroids and broad-spectrum antibiotics, use of contaminated infusion sets/fluid, and increase in intravenous drug abusers have been reported from those countries, it is expected to find a high rate of IA among patients with high risk, though hard data is missing in most situations. Besides classical risk factors for IA, liver failure, chronic obstructive pulmonary disease, diabetes, and tuberculosis are the newly recognized underlying diseases associated with IA. In Asia, Africa and Middle East sino-orbital or cerebral aspergillosis, and Aspergillus endophthalmitis are emerging diseases and Aspergillus flavus is the predominant species isolated from these infections. The high frequency of A. flavus isolation from these patients may be due to higher prevalence of the fungus in the environment. Cerebral aspergillosis cases are largely due to an extension of the lesion from invasive Aspergillus sinusitis. The majority of the centers rely on conventional techniques including direct microscopy, histopathology, and culture to diagnose IA. Galactomannan, β-D glucan test, and DNA detection in IA are available only in a few centers. Mortality of the patients with IA is very high due to delays in diagnosis and therapy. Antifungal use is largely restricted to amphotericin B deoxycholate and itraconazole, though other anti-Aspergillus antifungal agents are available in those countries. Clinicians are aware of good outcome after use of voriconazole/liposomal amphotericin B/caspofungin, but they are forced to use amphotericin B deoxycholate or itraconazole in public-sector hospitals due to economic reasons.

    Sains Malaysiana, 2014;43:1737-1742.
    Prevalence of dermatomycoses varies from one centre to another due to many factors. Knowledge of local prevalence is useful to aid clinical diagnosis and treatment. Due to lack of data in Malaysia, this study aimed to look at the causes of dermatomycoses in Kuala Lumpur, Malaysia. Dermatological specimens including skin scrapings, hair and nail clippings were collected carefully from clinically suspected cases of dermatomycoses between 2008 and 2010. All cultures of skin, hair and nails that yielded positive fungal growth were included. Any fungal growth outside the streaking area, duplicate and incomplete data were excluded from the study. Three-hundred-fifty-eight patients were included. Male patients were slightly more than females with a ratio of 1.2:1. The median age was 53 years old with interquartile range of 38-64 years. More than half (53.6%) belonged to 20-60 years age group. Rates of culture isolation were 89.0% for nails, 56.2% for hair and 55.6% for skin. Five-hundred-twenty-two fungi were isolated from 358 clinical specimens. Non-dermatophyte moulds (NDMs) represented the largest group (50.5%; mainly Aspergillus species 18.7%), followed by yeasts (41.6%; mainly Candida species 26.8%) and dermatophytes (7.9%; mainly Trichophyton species 7.7%). In conclusion, NDMs and yeasts were more commonly isolated than dermatophytes from dermatological specimens in this centre. Current treatment regime that focuses on dermatophytes may be ineffective to treat dermatomycoses caused by NDMs or yeasts. Antifungal susceptibility study may be needed to guide therapy in recalcitrant cases.

    Domestic maid violence is an assault and coercive behaviour, which mainly includes physical, psychological and at times sexual too, by employer or household members of employer against a person hired as a domestic help. Maid abuse is well known but poorly documented in scientific literature. This is an important global issue. In this article, two illustrated cases of maid abuse are discussed. Their employers allegedly subjected both the victims to physical and psychological trauma. The physical examination of the victims showed poor state of clothing, nutrition, and presence of injuries of different duration. The bruises were irregular to patterned, and were inflicted by beating. Both cases had eczematous contact dermatitis over palms and soles, paronechia, and sub-ungal fungal infection due to unprotected working in wet conditions. In both cases, external ears were deformed like cauliflowers due to repeated trauma. All cases had multiple injuries of varying duration. In this paper, medico-legal and social issues related to maid abuse are also discussed in detail. A possible solution to minimise maid abuse is also suggested. This paper highlights and document maid abuse.
