Epidemiology of Invasive Fungal Infections in Latin America

The pathogenic role of invasive fungal infections (IFIs) has increased during the past two decades in Latin America and worldwide, and the number of patients at risk has risen dramatically. Working habits and leisure activities have also been a focus of attention by public health officials, as endemic mycoses have provoked a number of outbreaks. An extensive search of medical literature from Latin America suggests that the incidence of IFIs from both endemic and opportunistic fungi has increased. The increase in endemic mycoses is probably related to population changes (migration, tourism, and increased population growth), whereas the increase in opportunistic mycoses may be associated with the greater number of people at risk. In both cases, the early and appropriate use of diagnostic procedures has improved diagnosis and outcome

Oral Manifestations Associated to Paracoccidioidomicosis and Histoplasmosis

Objective: To determine the frequency and clinical forms of oral manifestations associated to Paracoccidioidomycosis (PCM) and Histoplasmosis. Material and Methods: 481 medical records of outpatients referred to the Medical Mycology Department were reviewed since 2009 to 2016. Data were analyzed using descriptive statistical methods. Results: 47 (9.77%) cases had oral manifestations, 29 (61.70%) were associated to PCM and 18 (38.29%) to histoplasmosis. For PCM, male-female ratio was 8:1 and 1:1 for histoplasmosis. The average age for PCM was 48 years old and 53 for histoplasmosis. All the PCM patients had more than 1 oral structure affected: 44.82% were gingival lesions and 27.58% palate. In patients with histoplasmosis, 6 (33.33%) were lesions affecting palate and 6 (33.33%) involving tongue. For both entities, painful ulcers and granulomatous-like lesions were the most prevalent clinical forms; however, we observed a wide range of other oral manifestations. Regarding PCM patient’s comorbidities, 3 (10.34%) cases had HIV/AIDS, 8 (27.58%) histoplasmosis and 2 (6.89%) carcinomas. Whereas the comorbidities of patients with histoplasmosis, 2 (11.11%) had HIV/AIDS and 1 (5.55%) had carcinoma. Conclusion: In endemic countries for both mycoses, dentists must be aware of patients with mouth lesions, take advantage of epidemiologic clues that suggest risk factors and be acquainted with all the current diagnostic tests in order to make a quick diagnosis and treatment in highly suspicious cases
