Epstein-Barr Virus-Associated Carcinoma of the Larynx: A Systematic Review with Meta-Analysis.

Over the past few decades, several publications have investigated the role of Epstein-Barr virus (EBV) in head and neck squamous cell carcinomas, and an increasing number of them have shown its presence in laryngeal tumors. The purpose of this meta-analysis was to evaluate the association of EBV with laryngeal carcinoma. The search was carried out in two databases, Scopus and PubMed, using the following terms: "Epstein-Barr virus" and "laryngeal carcinoma". A total of 187 records were found, of which 31 were selected for meeting the inclusion and exclusion criteria. The meta-analysis yielded an overall pooled prevalence of 43.72% (95% confidence interval (CI): 34.35-53.08). Studies carried out in Europe and Eurasia had slightly higher pooled prevalence than other subgroups, while the prevalence of studies performed in developed countries was higher than in developing countries (46.37% vs. 34.02%). Furthermore, laryngeal carcinoma occurred almost three times as often among EBV-infected individuals compared to those without EBV infection (odds ratio = 2.86 (95% CI: 1.18-6.90); Begg's test, p = 0.843 and Egger's test, p = 0.866). Our findings support the idea that EBV is related to laryngeal carcinoma. However, further studies are needed before recognizing a definitive etiological role of EBV in the development and/or progression of laryngeal carcinomas.

American cutaneous leishmaniasis in a northeast Brazilian city: clinical and epidemiological features.

INTRODUCTION: This study characterized the clinico-epidemiological profile of American cutaneous leishmaniasis (ACL) cases in Barbalha, Ceará State, Brazil. METHODS: Medical records of 363 patients visiting Federal University of Cariri between 2009 and 2014 were analyzed. RESULTS: ACL was more prevalent in men with low education level from rural zones. The main presentation was a single ulcer, mainly in the lower limbs, and 49.8% also presented lymphadenomegaly. The annual incidence ranged from 2.83 to 22.60 per 10,000 inhabitants. CONCLUSIONS: The rates observed in this study indicate the importance of additional research to contribute to the control of this endemic disease.

Atypical presentations of cutaneous leishmaniasis: A systematic review.

Cutaneous Leishmaniasis (CL) is endemic in 88 countries, showing relevant prevalences. The aim of this study was to perform a systematic review on atypical lesions of CL around the world, addressing clinico-epidemiological, immunological and therapeutic aspects. A search of the literature was conducted via electronic databases Scopus and PubMed for articles published between 2010 and 2015. The search terms browsed were "cutaneous leishmaniasis", "atypical" and "unusual". Based on the eligibility criteria, 34 out of 122 articles were included in the final sample. Atypical lesions may include the following forms: erythematous volcanic ulcer, lupoid, eczematous, erysipeloid, verrucous, dry, zosteriform, paronychial, sporotrichoid, chancriform and annular. In any cases, they seem to be another disease like subcutaneous and deep mycosis, cutaneous lymphoma, pseudolymphoma, basal and squamous cell carcinoma. The lesions have been reported in the face, cheeks, ears, nose, eyelid, limbs, trunk, buttocks, as well as in palmoplantar and genital regions; sometimes occurring in more than one area. The reason for clinical cutaneous leishmaniasis pleomorphism is unclear but immunosuppression seems to play an important role in some cases. There are no established guidelines for the treatment of atypical cutaneous leishmaniasis. However, pentavalent antimonials remain as first line treatment for all forms of leishmaniasis even for HIV-infected patients and atpical forms. Finally, to diagnose an atypical lesion properly, the focus has to be on the medical history and the origin of the patient, comparing them to the natural history of leishmaniasis and always reminding of possible atypical presentations, to then start searching for the best diagnostic method and treatment, reducing the misdiagnosis rate and, subsequently, controlling the disease progression. Thereby, contributing for breaking the transmission chain of the parasite, due to early correct diagnosis which, in turn, contributes to reduce the prevalence.
