Knowledge, Attitudes, and Practices of Filipino Medical Interns on the Management of Superficial Cutaneous Mycoses: A Cross-sectional Study.

Background: Superficial mycoses are one of the most common skin conditions encountered in the outpatient clinics, causing significant morbidity amongst patients. Since these are highly prevalent diseases of the skin, the general practitioner should be able to manage uncomplicated cases, with no need for evaluation by a specialist. Objectives: The study aimed to determine the knowledge, attitudes, and practices of Filipino medical interns on the management of superficial cutaneous mycoses using a self-administered questionnaire. This may help identify possible gaps in knowledge, as well as obstacles these future clinicians may encounter when managing superficial mycoses. This in turn may assist in the development or improvement of dermatology training among medical students and continuing medical education programs amongst non-dermatologist physicians. Methods: This is a descriptive cross-sectional study among medical interns of the Philippine General Hospital to investigate their knowledge, attitudes, and practices regarding the management of superficial mycoses. Eligible participants were asked to complete an online self-administered survey questionnaire which assessed their capacity to recognize and manage uncomplicated superficial mycoses, and determined their attitudes regarding dermatology training in medical school. Results: The study included 170 medical interns, with majority having only 1-4 weeks of cumulative duration of dermatology training in medical school. Many of the participants (67.1%) had inadequate overall knowledge scores, but this was not significantly associated with their cumulative duration of dermatology training, as well as with their frequency of encounters with superficial mycosis patients. Most deem dermatology training (92.4%) and learning about the management of superficial mycoses (91.2%) during medical school very important. Majority are interested in attending more courses or training in the subject. Recommendations to improve medical school training on superficial mycoses include more practical approach in dermatology modules, integration of dermatology electives in medical school, and longer duration of dermatology modules/rotations during medical school. CONCLUSION: While knowledge scores of medical interns were not significantly associated with the duration of their dermatology training during medical school as well as their encounters with patients with superficial mycoses, it is shown that they have low confidence scores regarding management of superficial mycoses. They deem that learning more about this disease and dermatology in general is vital to their medical education and are desirous of more training in this subject. Recommendations to improve medical school training on superficial mycoses include dermatology modules, rotations or electives in medical school. Additionally, better training during medical school, and formulation of clinical practice guidelines specific to cutaneous mycoses were recommended to improve healthcare delivery for patients with such diseases.

Skin mycosis distribution, and burden of visits over a decade in Colombia: ecological study.

Objectives: To describe the sociodemographic distribution of dermatomycosis and the visits burden over a 10-year period of care. Methods: An ecological study was conducted using data on visits and people treated in the Colombian Health System during 2010-2019 using the International Classification of Diseases, Tenth Revision codes (ICD-10). Departments and geopolitical regions were the units of analysis, and visit burden was reported as frequency, intensity (visits per person), and rate of dermatomycosis visits (per 10,000 visits; 95% confidence interval). Results: A total of 4,570,593 visits were analyzed. The most used ICD-10 codes were B369 (superficial mycosis, unspecified), B360 (pityriasis versicolor), B354 (Tinea corporis), B359 (dermatophytosis), and B351 (Tinea unguium) (56.5%), with visits primarily involving the adult population (27-59 years; 32.2%), women (43.4%), and urban populations (57.3%). Amazonas department had the highest rate of visits (2.36 per 10,000), while Nariño had the highest intensity of visits (1.94 visits per person). Caribbean region had the highest rate of visits (17.0 per 10,000 visits; 17.0-17.0), followed by the Amazon region (16.3 per 10,000 visits; 16.2-16.4). Conclusions: The annual visits burden of dermatomycosis in Colombia is high and concentrated in susceptible geographic areas, possibly due to socio-environmental factors. This health problem is overshadowed by chronic diseases and trauma but is often recurrent, and chronic, and induces out-of-pocket costs for treatment.

Recognition of Antifungal-Resistant Dermatophytosis by Infectious Diseases Specialists, United States.

Antifungal-resistant dermatophyte infections have recently emerged as a global public health concern. A survey of US infectious diseases specialists found that only 65% had heard of this issue and just 39% knew how to obtain testing to determine resistance. Increased clinician awareness and access to testing for antifungal-resistant dermatophytosis are needed.

Global burden of fungal skin diseases: An update from the Global Burden of Diseases Study 2019.

BACKGROUND: Fungal skin diseases are the most common and widespread fungal infections, exerting a significant impact on patients' socio-psychological health and the quality of life. OBJECTIVES: To assess and compare the global burden of fungal skin diseases in 2019 and over the past 30 years. METHODS: Data were retrieved from the Global Burden of Disease Study 2019. Incidence and years lived with disability (YLDs) were used to assess the burden of fungal skin diseases. A total of 204 countries and territories were hierarchically organised into 21 regions and seven super-regions. Data were presented as absolute numbers and rates per 100,000 population, stratified by sex, age, year and location. RESULTS: In 2019, the global incidence rate and YLD rate of fungal skin diseases were 21,277 (95% UI 19 298-23,399) and 42 (95% UI 17-88) per 100,000 population, respectively. Sub-Saharan Africa bore the heaviest disease burden, especially children aged 5-9 years had a significantly higher incidence rate, YLD rate and YLDs to incidence ratio compared to other regions. Moreover, more than half of the incident cases among the elderly came from high-income regions and Southeast Asia, East Asia, and Oceania. Over the past 30 years, the number of incident cases and YLDs of fungal skin diseases has been continuously increasing worldwide, but the incidence rates and YLD rates have not shown significant changes. CONCLUSIONS: The global burden of fungal skin diseases has been continuously rising. Children in Sub-Saharan Africa are experiencing higher disease incidence and severity compared to other regions.

Awareness of people using municipal swimming pools about the prevention, symptoms, and treatment of athlete's foot and onychomycosis before COVID-19.

Introduction: Superficial mycosis is one of the most common diseases worldwide; however, its epidemiology is changing over time. Aim: To present the awareness of people using swimming pools about athlete's foot and onychomycosis. Material and methods: A total of 690 participants were subjected to an extensive survey administered via Google Documents. The questionnaire consisted of 30 online polling items and aimed to evaluate respondents' knowledge pertaining to fungal infections, encompassing aspects such as prevention strategies, disease trajectory, and therapeutic modalities. The survey sample specifically encompassed students and sports enthusiasts associated with 33 Internet groups, and data collection transpired during the period spanning 12 January to 15 March, 2018, predating the advent of the COVID-19 pandemic. Results: In the study, 85.2% of participants regularly inspected their feet, with 4.8% seeking podiatric services. While 75.2% demonstrated hygienic behaviour by changing towels after each pool visit, 41.4% acknowledged sharing nail tools. Notably, 75.7% preferred professional assistance for symptoms, with 24.3% opting for home remedies. Gender disparities were evident, with women showing significantly better hygiene practices and pool usage than men (p < 0.001). Women also exhibited a stronger tendency to disinfect grooming tools and prioritise sterility during beautician services (p < 0.001). These findings emphasise the importance of gender-specific health behaviour analysis in promoting preventive measures. Conclusions: The study highlights onychomycosis as a significant societal concern. Pre-COVID-19, awareness among municipal swimming pool users regarding prevention, symptoms, and treatment of athlete's foot and onychomycosis was insufficient.

Synergistic activity between conventional antifungals and chalcone-derived compound against dermatophyte fungi and Candida spp.

The scarce antifungal arsenal, changes in the susceptibility profile of fungal agents, and lack of adherence to treatment have contributed to the increase of cases of dermatomycoses. In this context, new antimicrobial substances have gained importance. Chalcones are precursors of the flavonoid family that have multiple biological activities, have high tolerability by humans, and easy synthesis. In this study, we evaluated the in vitro antifungal activity, alone and in combination with conventional antifungal drugs, of the VS02-4'ethyl chalcone-derived compound against dermatophytes and Candida spp. Susceptibility testing was carried out by broth microdilution. Experiments for determination of the target of the compound on the fungal cell, time-kill kinetics, and toxicity tests in Galleria mellonella model were also performed. Combinatory effects were evaluated by the checkerboard method. Results showed high activity of the compound VS02-4'ethyl against dermatophytes (MIC of 7.81-31.25 µg/ml). The compound targeted the cell membrane, and the time-kill test showed the compound continues to exert gradual activity after 5 days on dermatophytes, but no significant activity on Candida. Low toxicity was observed at 250 mg/kg. Excellent results were observed in the combinatory test, where VS02-4'ethyl showed synergistic interactions with itraconazole, fluconazole, terbinafine, and griseofulvin, against all isolates tested. Although further investigation is needed, these results revealed the great potential of chalcone-derived compounds against fungal infections for which treatments are long and laborious.

Potential Sexual Transmission of Antifungal-Resistant Trichophyton indotineae.

We describe a case of tinea genitalis in an immunocompetent woman in Pennsylvania, USA. Infection was caused by Trichophyton indotineae potentially acquired through sexual contact. The fungus was resistant to terbinafine (first-line antifungal) but improved with itraconazole. Clinicians should be aware of T. indotineae as a potential cause of antifungal-resistant genital lesions.

Management of tinea capitis in infants and children in the United States: A national survey of pediatric dermatologists.

This study aimed to evaluate the current management of tinea capitis in the United States, specifically focusing on patients aged 0-2 months, 2 months to 2 years, and 2 years to 18 years. An online survey, distributed through the Pediatric Dermatology Research Alliance and the Society of Pediatric Dermatology, revealed the following preferences: fluconazole for those under 2 months, griseofulvin for those aged 2 months to 2 years, and terbinafine for those aged 2 years and older. There exists inter-provider variation in tinea capitis treatment regimens within the pediatric dermatology community.

Tinea capitis outbreak and other superficial mycosis in an urban community of Medellín / Brote de tinea capitis y otras micosis superficiales en una comunidad urbana de Medellín

Introduction. Dermatophytoses are superficial fungal infections of the keratinized epithelium like tinea capitis. The latte mainly affects school-vulnerable populations. Carpinelo is a peripheral neighborhood in Medellín with poor socioeconomic conditions and where a suspected tinea capitis outbreak took place. Objective. To study and characterize, clinically and microbiologically, patients with suspected dermatophytosis in Carpinelo. Material and methods. We carried out a descriptive and longitudinal study with an active case search of tinea capitis in children and their relatives from the Jardín Educativo Buen Comienzo community in Carpinelo. Patients were clinically evaluated, and samples of scales and hair were taken to perform mycological studies with a 10 % potassium hydroxide and culture in Sabouraud and Mycosel agar. We analyzed the data with the statistical program SPSS™. 25 version. Results. Fifty-seven individuals were studied: 47 were children with a mean age of six years and a ratio of 2:1 male to female. Patients with confirmed diagnosis presented the following clinical forms: tinea capitis (78.95%), tinea faciei (15.79%) or tinea corporis (10.52%). Out of the total, 69.76% of the patients had previous treatment with steroids. The direct test was positive in 53.84% of the samples, and 46.15% had positive cultures. The isolated species were: Microsporum canis (77.77%), Trichophyton spp. (11.11%), Trichophyton rubrum (5.55%), and Malassezia spp. (5.55 %). Conclusion. Tinea capitis was the most common clinical form, and M. canis was the most frequently isolated species. The use of steroids as the first and only option for empiric treatment was worth of notice. The findings of this study point out the importance of microbiological diagnosis in choosing the best treatment for the patients.

Cromoblastomicosis verrugosa-cicatricial multifocal: una entidad desatendida en Colombia / Multifocal verrucous-cicatricial chromoblastomycosis: a neglected disease in Colombia

La cromoblastomicosis es una micosis subcutánea crónica de presentación clínica heterogénea que afecta principalmente a poblaciones de escasos recursos, lo que sumado al acceso limitado a los servicios de salud condiciona el retraso en el diagnóstico y tratamiento, ocasionando secuelas físicas graves. Se describe el caso de un hombre de 50 años con lesiones cutáneas verrugosas y cicatriciales de 30 años de evolución en la extremidad inferior y mano izquierda, además en cara en los últimos cinco años. Se realizó el diagnóstico de cromoblastomicosis de presentación multifocal y clínica mixta, con examen directo e histopatología compatibles, y cultivo para hongos positivo para Fonsecaea pedrosoi. Se indicó tratamiento oral con itraconazol y seguimiento clínico. Reconocer esta entidad es crucial para un diagnóstico y tratamiento oportunos, con el fin de evitar secuelas físicas y estigmatización secundaria. Se debe fortalecer en la atención primaria el reconocimiento de patologías desatendidas y de incidencia subestimada en Colombia, con una presentación multifocal mixta atípica y de un tiempo de evolución prolongado. El examen directo KOH es un herramienta accesible y económica en los primeros niveles de atención que puede contribuir al enfoque diagnóstico.

Chromoblastomycosis is a chronic subcutaneous mycosis with heterogeneous clinical presentation. It mainly affects low-income populations, which added to limited access to health services delays diagnosis and treatment, causing serious physical sequelae. We describe the case of a 50-year-old man with warty and cicatricial skin lesions of 30 years of evolution, at the level of left lower limb and left hand, with face involvement in the last five years. A diagnosis of chromoblastomycosis with multifocal and mixed clinical presentation was made, based on compatible direct examination and histopathology, and positive fungal culture for Fonsecaea pedrosoi. Oral treatment with itraconazole and clinical followup were stablished. Recognizing this entity is crucial for timely diagnosis and treatment, to avoid physical sequelae and secondary stigmatization. Primary health care should be strengthened for the recognition of neglected diseases whose incidence is underestimated in Colombia, with an atypical mixed multifocal presentation and a long evolution time. The KOH direct examination is an accessible and economical tool in the first levels of care that can contribute to the diagnostic approach.

Dermatology mycology diagnostics in Ireland: National deficits identified in 2022 that are relevant internationally.

BACKGROUND: Conventional testing methods for dermatophytes are time-consuming, and resource limitations in our institution have prompted curtailed access to these diagnostics. OBJECTIVES: Evaluation of our hospital's dermatological mycology diagnostic services and similar services nationally. METHODS: This was a retrospective observational study on skin, hair and nail mycology samples in our institution comparing twenty five-year periods (2011-2015 and 2016-2021), including analysis of dermatology clinic data and correspondence related to fungal infection. A survey of national public hospitals' laboratories was conducted to evaluate their mycology testing capabilities. RESULTS: The total 5 year test count prior to curtailment was 4851 specimens comprising 90% (n = 4344) from general practice and 6% (n = 290) from dermatology clinics. For the 5 years post curtailment, 64.5% (582/903) of specimens were from dermatology clinics. Dermatology clinic data demonstrated doubling of attendances (for all conditions) and of correspondence related to fungal infection. During this time also, national dermatological antifungal purchasing increased 11%. Ten of 28 Irish public hospital laboratories reported the provision of in-house dermatological mycology testing, and none had routine availability of susceptibility or molecular testing of dermatophytes. CONCLUSION: This study is the first to report an appraisal of dermatological fungal diagnostic services in Ireland. Insufficient testing capacity implies that patients are either being treated for fungal infection without appropriate diagnostic confirmation, or being left untreated because of the lack of access to diagnostics. The introduction of molecular detection methods and susceptibility systems would enhance testing capabilities and reduce the requirement for the external referral.

Kerion celsi caused by Trichophyton tonsurans in an adult

Abstract Tinea capitis is an uncommon infection in adults, and predominantly affects women and the elderly with hormonal disorders and immunosuppression. Clinical features are often polymorphic and atypical. A kerion celsi case in an elderly female patient with type 2 diabetes mellitus and menopause is presented. The diagnosis was established by direct examination and the isolation of Trichophyton tonsurans in culture and typified by microculture. Treatment with prednisone and itraconazol was very successful. Recognizing the presentation of tinea capitis in adults will help clinicians to avoid delay in the diagnosis, awareness of the risk factors and provide early treatment to minimize sequelae of the disease.

Factors influencing epidemiology of dermatomycoses at Gdansk, Poland and Grodno, Belarus.

Introduction: An increase in numbers of cutaneous fungal infections is being observed around the world. Dermatomycoses occur in every age group and can significantly decrease quality of life. Examining the prevalence and epidemiological trends of cutaneous fungal infections is necessary for developing new effective preventive, diagnostic and therapeutic methods. Many factors can influence the growth and patterns of global spread of the different species of fungi. Aim: To investigate the differences between the prevalence of dermatophytes and cutaneous fungal infections observed at two mycological laboratories and their plausible causes. Material and methods: Mycological examination was performed in 7324 patients in Gdansk, Poland and in 4729 patients in Grodno, Belarus who exhibited clinical signs and symptoms of cutaneous fungal infections. Direct preparations was made in 20% KOH with 40% DMSO. Additionally cultures were prepared on modified Sabouraud dextrose agar. Results: Dermatophytes were cultured in 642 (53.58%) cases in Gdansk. The most common species of dermatophytes were Trichophyton rubrum (306 cases), Trichophyton mentagrophytes var. granulosum (193 cases) and Microsporum canis (127 cases). Yeasts were isolated in 531 (44.40%) cases out of which Candida albicans was the most frequently identified in 323 cases. Similarly, dermatophytes were the most common in 1158 (68.72%) cases in Grodno. Candida were isolated in 527 (31.28%) cases. Analysing the localization of dermatomycoses onychomycosis was observed in majority of the infected patients in Gdansk. In Grodno the most common location of superficial cutaneous infection was tinea corporis In the Gdansk region dermatomycoses were observed in 688 female patients and in 508 male patients. In Grodno the prevalence is inverted with the majority of cases observed in 921 males and 764 females. Conclusions: The prevalence of superficial fungal infections is higher in Grodno, Belarus when compared to Gdansk, Poland. Similarly, dermatophytes were most commonly observed in both Laboratories.
