- Abstract
The etiology of tinea capitis changes over time, mainly due to trends in migration. We report 19 cases of tinea capitis caused by Microsporum audouinii, an uncommon agent in South America, all of them confirmed by molecular methods. All patients were male. The average age was 6.1 years. Fifteen patients were residents of Rio de Janeiro city and four were from neighboring cities. Among the patients submitted to follow-up, griseofulvin was prescribed for eight of them. Due to medication shortages, terbinafine was prescribed for five patients, needing to be switched in three cases, with a bigger total average time until clinical improvement. The study reaffirms the emergence of a new etiological agent in Rio de Janeiro, Brazil., (© The Author(s) 2024.

- Abstract
A 47-year-old woman who lived in the metropolitan area of Rio de Janeiro and had abandoned her Acquired Immune Deficiency Syndrome (AIDS) therapy 3 years prior, was admitted to our hospital due to weight loss, cough, and fever for 2 weeks. The dermatologic examination established normochromic papules with molluscum-like central umbilication on the face (Figure 1) and hands, erythema and infiltration in the oral cavity (Figure 2), desquamative patches on the legs, and ulceration on right calcaneus (Figure 3). Her CD4 (T-cells) count was 47 cells/ mm.
3 Direct mycology examination and cultures for several agents were performed. The mycology culture done from her skin and sputum grew Sporothrix 1 week after admission (Figure 4).- Published

- Abstract
Fusarium species are filamentous fungi widely encountered in nature, and may cause invasive disease in patients with hematologic conditions. Patients at higher risk are those with acute leukemia receiving induction remission chemotherapy or allogeneic hematopoietic cell transplant recipients. In these hosts, invasive fusariosis presents typically with disseminated disease, fever, metastatic skin lesions, pneumonia, and positive blood cultures. The prognosis is poor and the outcome is largely dependent on the immune status of the host, with virtually a 100% death rate in persistently neutropenic patients, despite monotherapy or combination antifungal therapy. In this paper, we will review the epidemiology, clinical manifestations, diagnosis, and management of invasive fusariosis affecting patients with hematologic diseases.

- Abstract
Background: Epidemiological studies indicate that onychomycosis may affect up to 79% of psoriatic patients. Onychomycosis in psoriatic patients is more commonly caused by yeasts comparing with non-psoriatic., Objectives: Evaluate the prevalence of fungi in nail psoriasis. Evaluate the association between direct mycological examination (DME) and mycological culture, Nail Psoriasis Severity Index (NAPSI) and systemic treatment for psoriasis., Methods: Of 133 nails from 20 patients with nail psoriasis were evaluated as follows: 9 patients were using topical treatment and 11 were on systemic treatment. The assessment of psoriasis severity using NAPSI was performed in all psoriatic nails. The presence of fungi was confirmed in DME and culture., Results: DME showed the presence of fungal elements in 45 nails (33.83%) with a predominance of blastoconidia (95.5%) No septate hyphae were seen. Mycological culture was positive in 36 (27.06%) samples. Among them, Candida grew in 31 (86.1%): Candida parapsilosis in 15 (48.38%), Candida spp in 14 (45.16%). No growth of dermatophytes was observed. Patients with systemic treatment showed a higher frequency of positive test (DME and culture) for fungi when compared to topic treatment (p:.006). There was a positive correlation between NAPSI, mycological culture and systemic treatment (p:.0063); the risk was four times higher (OR:4.0)., Limitation of the Study: Sample size., Conclusion: These results are consistent with some previous reports, Candida was the fungus with higher frequency on the psoriatic nails, however, the role of these fungi is controversial (contamination x colonisation x infection). The fact that the immunosuppressive treatment increases the chance of fungal infection leads us to a greater attention to this patient profile, to prevent the intensification of nail psoriasis (Köbner phenomenon)., (© 2021 Wiley-VCH GmbH.)

- Abstract
Candidemia is a major complication in hematopoietic cell transplantation (HCT), and antifungal prophylaxis with fluconazole decreases the incidence of this complication. We compared 2 strategies for fluconazole prophylaxis in patients with hematologic malignancy undergoing autologous HCT between 1997 and 2017. From 1997 to 2003, fluconazole prophylaxis (400 mg/d) was given to all HCTs, started with the conditioning regimen (early prophylaxis), and given until neutrophil engraftment or the need of non-prophylactic antifungal therapy. From 2004 on, fluconazole (400mg daily) was started only if (and when) the patient developed oral mucositis (late prophylaxis). Among 571 HCT, 270 received early prophylaxis, 112 received late prophylaxis, and 189 did not receive fluconazole because they did not develop oral mucositis. The incidence of candidemia was 1.8% in the early prophylaxis group, 0% in the late prophylaxis group, and 1.1% in the no prophylaxis group (P = .31). Among patients receiving fluconazole, the median duration of prophylaxis was 17 days (range, 6-36 days) in the early prophylaxis group and 6 days (range, 2-16 days) in the late prophylaxis group (P < .001). The initiation of fluconazole prophylaxis guided by the occurrence of oral mucositis (late prophylaxis) was as good as early fluconazole prophylaxis., (Copyright © 2021 The American Society for Transplantation and Cellular Therapy.

- Abstract
Background: The incidence of candidemia in our hospital has been stable over an 18-year period (1.3 episodes per 1000 admissions). Since March 2020, we have observed an increase in cases of candidemia., Methods: In March 2020, the hospital was prepared to receive patients with COVID-19, with cancellation of elective procedures, discharge of less sick patients and the activation of beds for COVID-19. We compared the incidence of candidemia in 2 periods: from January 2019 to February 2020 (period 1) and from March to September 2020 (period 2)., Results: We diagnosed 41 episodes of candidemia, 16 in period 1 and 25 in period 2 (9 COVID-19 patients). Compared with non-COVID-19 patients, COVID-19 patients with candidemia were more likely to be under mechanical ventilation (100% vs. 34.4%, P < .001). The median number of monthly admissions in period 1 and 2 was 723 (interquartile range 655-836) and 523 (interquartile range 389-574), respectively. The incidence of candidemia (per 1000 admissions) was 1.54 in period 1 and 7.44 in period 2 (P < .001). In period 2, the incidence of candidemia (per 1000 admissions) was 4.76 if we consider only cases of candidemia in non-COVID-19 patients, 2.68 if we consider only cases of candidemia in COVID-19 patients and 14.80 considering only admissions of patients with COVID-19., Conclusions: The increase in the incidence of candidemia in our hospital may be attributed to 2 factors: a reduction in the number of admissions (denominator) and the occurrence of candidemia in COVID-19 patients., (© 2020 Wiley-VCH GmbH.)

- Abstract
Invasive fusariosis (IF) usually presents with high fungal burden at diagnosis, and this may contribute to its high mortality rate. The use 1,3-beta-D-glucan (BDG) may help to establish the diagnosis at an earlier disease stage and to monitor treatment. To evaluate the performance of BDG in the diagnosis of IF and its kinetics in relation to the outcome, we retrospectively tested serum samples of 13 cases of IF, analysed the temporal relationship between the first positive BDG test and the date of the diagnosis of IF, and the kinetics of BDG in relation to patients' outcome. We selected 13 controls with similar underlying diseases as cases, at least two serum samples stored, and no invasive fungal disease. Twelve patients with IF had at least one positive BDG (median 4, range 1-16). The test was positive before the diagnosis of IF in 11 of the 12 patients (91.6%), at a median of 10 days (range 1-32). The median BDG value increased (from 109 to 316 pg/mL, P = 0.04) in patients who died by day 30, and did not change significantly (99-101 pg/mL, P = 0.60) in survivors. Using two consecutive BDG tests, sensitivity, specificity, and positive and negative predictive values were 85%, 69%, 7% and 99%, respectively. BDG is positive in the majority of patients with IF, usually before the diagnosis, but the low positive predictive value limits its use to diagnose IF earlier. Once therapy is started, decreasing BDG values suggests treatment response., (© 2019 Blackwell Verlag GmbH.)

Ferreira TA, Trope BM, Barreiros G, Quintela DC, and Ramos-E-Silva M
- Abstract
Sporotrichosis is an infection caused by fungi of the Sporothrix complex. The clinical lymphocutaneous presentation corresponds to the great majority of cases. With the increased incidence of sporotrichosis in the State of Rio de Janeiro, Brazil, atypical clinical forms have been reported with increasing frequency, usually associated with immunosuppression. We report the case of a 47-year-old female, with HIV and disseminated sporotrichosis, presenting molluscum-like skin lesions, as well as lung, nasal, and oral mucosa involvement. We also report the first demonstration of culture of Sporothrix in scales of the skin lesion, a fact not identified in the consulted literature.

- Abstract
Background: Candidemia is the most frequent invasive fungal disease in hospitalized patients, and is associated with high mortality rates. The main objective of this study was to evaluate changes in the epidemiology of candidemia at a tertiary care hospital in a 21-year period., Methods: We evaluated all episodes of candidemia diagnosed between 1996 and 2016 at a University-affiliated tertiary care hospital in Brazil. We arbitrarily divided the study period in 3: 1996-2002 (period 1), 2003-2009 (period 2) and 2010-2016 (period 3). Incidence rates were calculated using hospital admissions as denominator., Results: We observed 331 episodes of candidemia. The incidence was 1.30 episodes per 1000 admissions, with no significant change over time. Candida albicans (37.5%), C. tropicalis (28.1%), C. parapsilosis (18.4%) and C. glabrata (6.9%) were the most frequent species. The proportion of patients receiving treatment increased (65.5%, 79.4% and 74.7% in periods 1, 2 and 3, respectively, p = 0.04), and the median time from candidemia to treatment initiation decreased from 4 days in period 1 (range 0-32 days) to 2 days in period 2 (range 0-33 days) and 2 days in period 3 (range 0-14 days, p < 0.001). We observed a significant decrease in the use of deoxycholate amphotericin B (47.4%, 14.8% and 11.9%), and an increase in the use of echinocandins (0%, 2.8% and 49.1%; p < 0.001). The APACHE II score increased over time (median 16, 17.5, and 22, p < 0.001). The overall 30-day mortality was 58.9%, and did not change significantly over the study period., Conclusions: There was an improvement in patient care, with an increase in the proportion of patients receiving treatment and a decrease in the time to treatment initiation, but no improvement in the outcome, possibly because the proportion of sicker patients increased over time., (Copyright © 2018 Sociedade Brasileira de Infectologia.

- Abstract
Fonsecaea spp. are melanized fungi which cause most cases of chromoblastomycosis. The taxonomy of this genus has been revised, now encompassing four species, with different pathogenic potential: F. pedrosoi, F. nubica, F. pugnacius, and F. monophora. The latter two species present wider clinical spectrum and have been associated with cases of visceral infection, most often affecting the brain. To our knowledge, this is the first report of proven case of F. monophora respiratory tract infection. A Brazilian 57-year-old-female patient underwent kidney transplantation on January 12, 2013. On the fourth postoperative month, the patient presented with fever, productive cough, and pleuritic pain in the right hemithorax. A thoracic CT scan showed a subpleural 2.2-cm nodular lesion in the right lung lower lobe, with other smaller nodules (0.5-0.7 cm) scattered in both lungs. Bronchoscopy revealed a grayish plaque on the right bronchus which was biopsied. Microscopic examination demonstrated invasion of bronchial mucosa by pigmented hyphae. Culture from the bronchial biopsy and bronchoalveolar lavage samples yielded a melanized mold, which was eventually identified as F. monophora. She started treatment with voriconazole (400 mg q.12h on the first day, followed by 200 mg q.12h). After 4 weeks of therapy, voriconazole dose was escalated to 200 mg q.8h and associated with amphotericin B (deoxycolate 1 mg/kg/day) because of a suspected dissemination to the brain. The patient eventually died of sepsis 8 weeks after the start of antifungal therapy. In conclusion, F. monophora may cause respiratory tract infection in solid organ transplant recipients.

- Abstract
Sporotrichosis is the subcutaneous mycosis caused by several species of the Sporothrix genus. With worldwide occurrence, the State of Rio de Janeiro is presently undergoing a zoonotic sporotrichosis epidemic. The form of lymphocutaneous nocardiosis is rare, being caused especially by Nocardia brasiliensis. It appears as a nodular or ulcerated lesion, with multiple painful erythematous nodules or satellite pustules distributed along the lymphatic tract, similar to the lymphocutaneous variant of sporotrichosis. We present a 61-year-old man who, after an insect bite in the left leg, developed an ulcerated lesion associated with ascending lymphangitis, nonresponsive to previous antibiotic therapies. The patient was admitted for investigation, based on the main diagnostic hypothesis of lymphatic cutaneous sporotrichosis entailed by the highly suggestive morphology, associated with the epidemiologic information that he is a resident of the city of Rio de Janeiro. While culture results were being awaited, the patient was medicated with sulfamethoxazole-trimethoprim to cover CA-MRSA and evolved with total healing of the lesions. After hospital discharge, using an ulcer fragment, an Actinomyces sp. was cultivated and N. brasiliensis was identified by molecular biology. The objective of this report is to demonstrate a case of lymphocutaneous nocardiosis caused by N. brasiliensis after a probable insect bite. Despite the patient being a resident of the State of Rio de Janeiro (endemic region for sporotrichosis), it is highlighted that it is necessary to be aware of the differential diagnoses of an ulcerated lesion with lymphangitis, favoring an early diagnosis and appropriate treatment of the illness.

- Abstract
Hematologic patients with superficial skin lesions on admission growing Fusarium spp. are at a high risk for developing invasive fusariosis during neutropenia. We evaluated the impact of primary prophylaxis with a mold-active azole in preventing invasive fusariosis in these patients. Between August 2008 and December 2014, patients with acute leukemia or aplastic anemia and recipients of hematopoietic cell transplants were screened on admission with dermatologic and direct exams and fungal cultures of superficial skin lesions. Until November 2009, no interventions were made. Beginning in December 2009, patients with baseline skin lesions and a direct exam and/or culture suggestive of the presence of Fusarium spp. received prophylaxis with voriconazole or posaconazole. Skin lesions in the extremities (mostly onychomycosis and interdigital intertrigo) were present on admission in 88 of 239 episodes (36.8%); 44 lesions had hyaline septate hyphae identified by direct exam, and cultures from 11 lesions grew Fusarium spp. Antimold prophylaxis was given for 20 episodes (voriconazole for 17 and posaconazole for 3). Invasive fusariosis was diagnosed in 14 episodes (5.8%). Among patients with baseline skin lesions with positive cultures for Fusarium spp., 4 of 5 without antimold prophylaxis developed invasive fusariosis versus 0 of 6 with antimold prophylaxis (P = 0.01; 95% confidence interval for the difference between proportions, 22% to 96%). Primary antifungal prophylaxis with an antimold azole may prevent the occurrence of invasive fusariosis in high-risk hematologic patients with superficial skin lesions on admission growing Fusarium spp., (Copyright © 2016, American Society for Microbiology.

- Abstract
Building renovations increase the concentration of Aspergillus conidia in the air. In 2010, one wing of the hospital building was imploded due to structural problems. To evaluate the impact of building implosion on the concentration of fungi in the air, the demolition was performed in two phases: mechanical demolition of 30 m of the building, followed by implosion of the wing. Patients at high risk for aspergillosis were placed in protected wards. Air sampling was performed during mechanical demolition, on the day of implosion and after implosion. Total and specific fungal concentrations were compared in the different areas and periods of sampling, using the anova test. The incidence of IA in the year before and after implosion was calculated. The mean concentration of Aspergillus increased during mechanical demolition and on the day of implosion. However, in the most protected areas, there was no significant difference in the concentration of fungi. The incidence of invasive aspergillosis (cases per 1000 admissions) was 0.9 in the 12 months before, 0.4 during, and 0.5 in the 12 months after mechanical demolition (P > 0.05). Continuous monitoring of the quality of air and effective infection control measures are important to minimize the impact of building demolition., (© 2015 Blackwell Verlag GmbH.)

- Abstract
Objectives: To evaluate the frequency of skin colonization by Fusarium spp. in high-risk hematologic patients and its impact on the subsequent development of invasive fusariosis., Methods: We screened all high-risk hematologic patients from August 2008 to December 2009 with cultures of 6 pre-defined areas in the feet and hands on admission and at discharge. In addition, cultures of any skin lesion present on admission were performed., Results: Among 61 patients screened, alterations in the skin and/or nails were present in 32 patients (52%) on admission, mostly represented by abnormal appearing nails and intertrigo. Four patients (7.2%) presented positive baseline cultures for Fusarium spp., all in existing lesions of onychomycosis, intertrigo or both. Invasive fusariosis was diagnosed in six patients. The presence of a skin lesion at baseline that grew Fusarium spp. was associated with the subsequent development of invasive fusariosis (p = 0.04)., Conclusions: Our data suggest that: 1) baseline cultures in patients without alterations in the skin and/or nails seems not justifiable; 2) cultures of pre-existing lesions may help to identify a group of patients at higher risk to develop invasive fusariosis. The use of anti-mould prophylaxis in this setting should be explored in future studies., (Copyright © 2013 The British Infection Association. Published by Elsevier Ltd. All rights reserved.)

- Abstract
Invasive fusariosis (IF) is an infection with Fusarium spp. fungi that primarily affects patients with hematologic malignancies and hematopoietic cell transplant recipients. A cutaneous portal of entry is occasionally reported. We reviewed all cases of IF in Brazil during 2000-2010, divided into 2 periods: 2000-2005 (period 1) and 2006-2010 (period 2). We calculated incidence rates of IF and of superficial infections with Fusarium spp. fungi identified in patients at a dermatology outpatient unit. IF incidence for periods 1 and 2 was 0.86 cases versus 10.23 cases per 1,000 admissions (p<0.001), respectively; superficial fusarial infection incidence was 7.23 versus 16.26 positive cultures per 1,000 superficial cultures (p<0.001), respectively. Of 21 cases of IF, 14 showed a primary cutaneous portal of entry. Further studies are needed to identify reservoirs of these fungi in the community and to implement preventive measures for patients at risk.

- Abstract
Background: Invasive fusariosis (IF) is a rare but often fatal fungal infection in immunosuppressed patients. In 2007, cases of IF above the expected epidemiologic baseline were detected in the hematology ward of a hospital in Rio de Janeiro, Brazil. Possible sources of infection were investigated by performing environmental sampling and patient isolate collection, followed by molecular typing. Isolates from dermatology patients with superficial fusariosis were included in the study for comparison to molecular types found in the community., Methods: Environmental sampling focused on water-related sources in and around the hematology ward. Initially, we characterized 166 clinical and environmental isolates using the Fusarium translation elongation factor 1α (EF-1α) genetic locus. Isolates included 68 collected from water-related sources in the hospital environment, 55 from 18 hematology patients, and 43 from the skin/nails of 40 outpatients seen at the hospital dermatology clinic. Multi-locus sequence typing was performed on Fusarium solani species complex (FSSC) species 1 and 2 isolates to investigate their relatedness further., Results: Most of the hematology samples were FSSC species 2, with species type FSSC 2-d the most commonly isolated from these patients. Most of the outpatient dermatology samples were also FSSC 2, with type 2-d again predominating. In contrast, environmental isolates from water sources were mostly Fusarium oxysporum species complex (FOSC) and those from air samples mostly Fusarium incarnatum-equiseti species complex (FIESC). A third of the environmental samples were FSSC, with species types FSSC 1-a and FSSC 1-b predominating., Conclusions: Fusarium isolate species types from hematology patient infections were highly similar to those recovered from dermatology patients in the community. Four species types (FSSC 1-a, 1-b, 2-d and 2-f) were shared between hematology patients and the environment. Limitations in environmental sampling do not allow for nosocomial sources of infection to be ruled out. Future studies will focus on environmental factors that may have influenced the prevalence of FSSC fusariosis in this hematology ward.

- Abstract
From December 1996 through September 1997, we diagnosed 19 cases of fungemia due to Exophiala jeanselmei. We conducted a matched case-control study in which we cultured specimens of blood products, intravenous solutions, and water from a hospital water system. Isolates from environmental cultures were compared to those recovered from patients by random amplification of polymorphic DNA (RAPD). Multivariate analysis showed that neutropenia, longer duration of hospitalization, and use of corticosteroids were risk factors for infection. Environmental cultures yielded E. jeanselmei from 3 of 85 sources: deionized water from the hospital pharmacy, 1 water tank, and water from a sink in a non-patient care area. Use of deionized pharmacy water to prepare antiseptic solutions was discontinued, and no additional cases of infection occurred. RAPD typing showed that isolates from case patients and isolates from the pharmacy water were highly related, whereas the patterns of isolates recovered from the 2 other sources of water were distinct.

- Abstract
Fungi have become increasingly important causes of nosocomial bloodstream infections. The major cause of nosocomial fungemia has been Candida spp, but increasingly molds and other yeasts have caused disease. Exophiala jeanselmei and members of the genus Rhinocladiella are dematiaceous moulds, which have been infrequently associated with systemic infection and have not been described as causes of fungemia. In this paper, the occurrence of 23 cases of fungemia due to these organisms over a 10-month period is reported and the clinical characteristics of patients and outcomes are described. The majority of patients were immunosuppressed; 21 of 23 (91%) had received blood products and 78% had a central venous catheter. All patients had at least one manifestation of fever, but only one patient had signs or symptoms suggesting deep-seated infection. Antifungal therapy was given to 19 of the 23 patients; of those who did not receive therapy, 3 died prior to the culture result and 1 had been discharged without therapy. Antifungal susceptibility of the organisms showed activity of amphotericin B, itraconazole, and the new triazole antifungals voriconazole and posaconazole. E. jeanselmei and Rhinocladiella species are potential causes of nosocomial fungemia and may be associated with systemic infection.

- Abstract
In order to identify prognostic factors for death among cancer patients with fungemia, an 18-month survey of fungemia in patients with cancer was undertaken in three hospitals in Rio de Janeiro. For the assessment of risk factors for death, the following variables were analyzed: age; gender; underlying cancer; last treatment for the underlying disease; previous surgery; use of antibiotics, antifungal agents, steroids, or total parenteral nutrition; use of a central venous catheter; chemotherapy; radiotherapy; presence and duration of neutropenia; etiologic agent of the fungemia; treatment of the fungemia; clinical manifestations; and performance status (Karnofsky score) on the day of the positive blood culture. In multivariate analysis, the variables associated with an increased risk for death were older age, persistent neutropenia, and low performance status. Identifying risk factors for death may help to define a group-risk patients for whom new therapeutic options should be tried.

- Abstract
World areas with chloroquine-resistant falciparum malaria are progressively spreading, in Africa from East to West. We are reporting here a new case of resistance, grade III, from Cameroon, carried out in vitro by the WHO standard macrotest. Resistance is determined by the ability of trophozoites to develop into schizonts when therapeutic doses of chloroquine have been administered.
