The World Health Organization, in response to the growing burden of fungal disease, established a process to develop a fungal pathogen priority list. This systematic review aimed to evaluate the epidemiology and impact of infections caused by Talaromyces marneffei, Coccidioides species, and Paracoccidioides species. PubMed and Web of Sciences databases were searched to identify studies published between 1 January 2011 and 23 February 2021 reporting on mortality, complications and sequelae, antifungal susceptibility, preventability, annual incidence, and trends. Overall, 25, 17, and 6 articles were included for T. marneffei, Coccidioides spp. and Paracoccidioides spp., respectively. Mortality rates were high in those with invasive talaromycosis and paracoccidioidomycosis (up to 21% and 22.7%, respectively). Hospitalization was frequent in those with coccidioidomycosis (up to 84%), and while the duration was short (mean/median 3-7 days), readmission was common (38%). Reduced susceptibility to fluconazole and echinocandins was observed for T. marneffei and Coccidioides spp., whereas >88% of T. marneffei isolates had minimum inhibitory concentration values ≤0.015 μg/ml for itraconazole, posaconazole, and voriconazole. Risk factors for mortality in those with talaromycosis included low CD4 counts (odds ratio 2.90 when CD4 count <200 cells/μl compared with 24.26 when CD4 count <50 cells/μl). Outbreaks of coccidioidomycosis and paracoccidioidomycosis were associated with construction work (relative risk 4.4-210.6 and 5.7-times increase, respectively). In the United States of America, cases of coccidioidomycosis increased between 2014 and 2017 (from 8232 to 14 364/year). National and global surveillance as well as more detailed studies to better define sequelae, risk factors, outcomes, global distribution, and trends are required.

Review
Endemic systemic mycoses such as blastomycosis, coccidioidomycosis, histoplasmosis, talaromycosis, paracoccidioidomycosis are emerging as an important cause of morbidity and mortality worldwide. We conducted a systematic review on endemic systemic mycoses reported in Italy from 1914 to nowadays. We found out: 105 cases of histoplasmosis, 15 of paracoccidioidomycosis, 10 of coccidioidomycosis, 10 of blastomycosis and 3 of talaromycosis. Most cases have been reported in returning travelers and expatriates or immigrants. Thirtytwo patients did not have a story of traveling to an endemic area. Fortysix subjects had HIV/AIDS. Immunosuppression was the major risk factor for getting these infections and for severe outcomes. We provided an overview on microbiological characteristics and clinical management principles of systemic endemic mycoses with a focus on the cases reported in Italy.

Review
BACKGROUND
Advanced neuroimaging demonstrated that neurological involvement occurs in up to 30% of paracoccidioidomycosis (PCM) cases. Current knowledge of neuroparacoccidioidomycosis (NPCM) is based on a 2009 systematic review. However, in the last decade, several new cases have been published, with modern neuroimaging techniques.
OBJECTIVES
We believe a new systematic review is needed to summarise these advances.
METHODS
We searched PubMed/MEDLINE, Embase and LILACS for studies from January 2010 to May 2022. Case series and case reports of NPCM were included. We performed a metaproportion to estimate a summary proportion with 95% confidence intervals (CI).
RESULTS
Thirty-four studies including 104 patients were evaluated. We combined our data with the results from the previous review that included 257 cases, totalling 361 patients. We found no new important demographic, clinical or laboratory characteristics. On magnetic resonance imaging (MRI), we found that 72% (95%CI: 38-91) had hyperintensity on T1-weighted image; 84% (95%CI: 71%-92%) had hypointensity on T2-weighted image; 80% (95%CI: 66-89) had contrast enhancement with the classical ring-enhancing pattern. All 8 patients undergoing spectroscopy presented lipid peaks. We found a 16% mortality, lower than in the previous review (44%).
CONCLUSION
NPCM presents a characteristic pattern on MRI that may help to differentiate it from other causes of single or multiple brain lesions. Albeit there is a frequent pattern, it is not specific, as other granulomatous diseases may show similar findings. Advances in neuroimaging with early diagnosis and appropriate management of the disease may have contributed to reducing its mortality.

BACKGROUND
Paracoccidioidomycosis is a systemic mycosis considered endemic and limited to Latin America with the majority of registered cases originating from Brazil. The purpose of this paper was to report a case of a female patient with paracoccidioidomycosis mimicking inflammatory bowel disease and to systematically review available cases of the intestinal presentation of this infectious disease.
CASE REPORT
Female patient, 32-years old, previously asymptomatic, presenting with acute pain in the lower right abdomen, associated with signs of peritoneal irritation and abdominal distension. Urgent surgery was performed, which identified a severe suppurative perforated ileitis. The anatomopathological study revealed fungal structures shaped as a ship's pilot wheel in Grocott-Gomori's staining, suggestive of Paracoccidioides spp.
METHODS
Studies were retrieved based on Medical Subject Headings and Health Sciences Descriptors, which were combined using Boolean operators. Searches were run on the electronic databases Scopus, Web of Science, MEDLINE (PubMed), BIREME (Biblioteca Regional de Medicina), LILACS (Latin American and Caribbean Health Sciences Literature), SciELO (Scientific Electronic Library Online), Embase, and Opengray.eu. Languages were restricted to English, Spanish and Portuguese. There was no date of publication restrictions. The reference lists of the studies retrieved were searched manually. Simple descriptive analysis was used to summarize the results.
RESULTS
Our search strategy retrieved 581 references. In the final analysis, 34 references were included, with a total of 46 case reports. The most common clinical finding was abdominal pain and weight loss present in 31 (67.3%) patients. Most patients were treated with itraconazole (41.3%) and amphotericin B (36.9%). All-cause mortality was 12.8%.
CONCLUSIONS
Paracoccidioidomycosis should be suspected in endemics areas, specially as a differential diagnosis for inflammatory bowel disease. Endoscopic tests and biopsy are useful for diagnosis and treatment with antifungal drugs seem to be the first treatment option to achieve a significant success rate.

Review
Paracoccidioidomycosis is a systemic mycosis that is endemic in geographical regions of Central and South America. Cases that occur in nonendemic regions of the world are imported through migration and travel. Due to the limited number of cases in Europe, most physicians are not familiar with paracoccidioidomycosis and its close clinical and histopathological resemblance to other infectious and noninfectious disease. To increase awareness of this insidious mycosis, we conducted a systematic review to summarize the evidence on cases diagnosed and reported in Europe. We searched PubMed and Embase to identify cases of paracoccidioidomycosis diagnosed in European countries. In addition, we used Scopus for citation tracking and manually screened bibliographies of relevant articles. We conducted dual abstract and full-text screening of references yielded by our searches. To identify publications published prior to 1985, we used the previously published review by Ajello et al. Overall, we identified 83 cases of paracoccidioidomycosis diagnosed in 11 European countries, published in 68 articles. Age of patients ranged from 24 to 77 years; the majority were male. Time from leaving the endemic region and first occurrence of symptoms considerably varied. Our review illustrates the challenges of considering systemic mycosis in the differential diagnosis of people returning or immigrating to Europe from endemic areas. Travel history is important for diagnostic-workup, though it might be difficult to obtain due to possible long latency period of the disease.

UNLABELLED
Paracoccidioidomycosis (PCM) is an infection caused by fungi of the genus Paracoccidioides and is marked by a strong predilection for men; nevertheless, some women have had developed PCM and have presented oral involvement by the disease.
OBJECTIVES
To review all published cases until August 2020 of oral PCM in women, with emphasis on the presence of systemic changes, deleterious habits (tobacco and alcohol) and oral manifestation features through a systematic review.
METHODS
Observational studies (both prospective and retrospective) and case reports indexed in the Embase, PubMed, Scopus, Web of Science and LIVIVO databases were selected by two reviewers in a two-phase process following the pre-established PICOS criteria.
RESULTS
Twenty-five studies met the eligibility criteria and were selected for qualitative synthesis, of which 72 participants were enrolled. Brazilian White women between 40 and 50 years were the most affected and social history revealed them to be housewives or rural workers. Fifteen women (33.3% of the informed cases) presented any systemic change at the time of PCM diagnosis, namely pregnancy, HIV infection and/or depression. Moriform stomatitis was predominant and affected preferentially the gingivae and alveolar processes in the form of a single painful lesion. Most patients were treated with sulfamethoxazole + trimethoprim or itraconazole.
CONCLUSIONS
Oral PCM in women is rare; some cases showed systemic changes at the time of PCM diagnosis, namely HIV infection, pregnancy and depression. New studies should be conducted to elucidate the influence of systemic alterations on the development of oral PCM in women.

Meta-Analysis
OBJECTIVES
To analyse the accuracy of American tegumentary leishmaniasis (ATL) diagnostic methods and evaluate the quality of the existing publications by means of a systematic review.
METHODS
Diagnostic tests evaluated in at least two studies with common reference standards were included in the sensitivity and/or specificity meta-analyses. Quality and susceptibility to bias were analysed using the QUADAS-2 and STARD tools.
RESULTS
The title and abstract of 3387 publications were evaluated after deduplication resulting from database searches. Thirty-eight studies were included in the review, and 26 of them had results inserted in meta-analyses. The diagnostic methods with the highest pooled sensitivity values were ELISA, polymerase chain reaction (PCR), indirect immunofluorescence reaction and Montenegro's intradermal reaction. Cytometry was assessed in only two studies and presented 100% sensitivity in both. Smear slide microscopy and histopathology showed low pooled values of sensitivity. For specificity, the highest pooled values were identified for PCR. High values were also identified for ELISA, except for studies in which the reference standard for defining negative participants included individuals with Chagas' disease or paracoccidioidomycosis, which also occurred for cytometry. IFR had lower specificities than ELISA. There was a predominance of case-control designs of phase 1 or 2 and only four studies were strongly recommended as evidence generators. Several reference standards were adopted, and different methods were assessed in a small number of studies.
CONCLUSION
PCR showed the highest accuracy for the diagnosis of ATL, and its use should be encouraged in clinical practice. ELISA is recommended for the screening of suspected individuals, but the possibility of cross-reactions should be considered. New validation studies for the tests evaluated in few publications and studies of phase 3 with appropriate methods are needed.
