ABSTRACT

Central nervous system (CNS) fungal infections are challenging and difficult to diagnose and treat. This article introduces the high risk factors, pathogen spectrum and laboratory indicators that cause CNS fungal infection. As patients with CNS fungal infections are often accompanied by immunodeficiency, it is especially necessary for clinical early detection, early prevention, and early diagnosis, and timely and effective implementation of optimized diagnosis and treatment programs to prevent further deterioration of the disease.

ABSTRACT

Neuroparacoccidiodimycosis (NPDM) is an uncommon granulomatous disease, which more frequently affects immunocompromised male patients over 30 years of age in the course of chronic lung disease. Paracoccidioides brasiliensis (PB) is an endemic fungus in Brazil, and grows as thick-walled yeast (with round to oval bodies) measuring 10 µm to 60 µm in diameter. Neuroparacoccidiodimycosi may develop many years after transmission and/or primary lung involvement. The authors describe a case of NPDM affecting a male patient, 52 years of age, farmer, heavy smoker, with clinical complaint of headache, asthenia, seizures, and prostration in the previous nine months. Upon physical examination, the patient presented regular general condition, without other relevant physical alterations. Computed tomography (CT) showed multiple bilateral pulmonary nodules associated to enlargement of the mediastinal lymph node. Magnetic resonance imaging (MRI) and CTscans of the central nervous system showed six heterogeneous nodular lesions compromising the frontal and parietal lobes, the largest one measuring 3.8 3.2 3.2 cm. The hypothesis of a neoplastic process compromising the lung and brain was considered. A biopsy of the mediastinal lymph node showed epithelioid granulomas, which exhibited round, thin-walled fungal structures in Grocott silver stain. The stereotactic biopsy of the frontal lesion was constituted by necrotic tissue admixed with some round to oval, thin-walled fungi measuring 10 µm to 60 µm, compatible with PB (identified on Grocott silver stain/confirmed in culture). The diagnosis of NPDM was then established. The employed therapeutic regimen was intravenous amphotericin B, itraconazole, and sulfamethoxazole-trimetropin. After ninety days of clinical follow-up, no episodes of seizures/neurological deficits were identified, and a marked decrease in the number and size of the lung and brain lesions were found.

ABSTRACT

Paracoccidioidomycosis is a systemicmycosis caused by the Paracoccidioides brasiliensis fungus, which is endemic in Latin America. Brazil is the country with the highest number of cases. The affection of the central nervous system (CNS), a potentially fatal condition, occurs in 12% of the cases. The following forms of presentation are identified:meningeal, which is unusual;meningoencephalitic; and pseudotumoral, the latter two being more frequent. Imaging tests are essential for the diagnosis, but the histological identification of the fungus is required for confirmation of the pathology. The clinical picture depends on the neuraxial location.We present a case of amale rural worker, with expansive lesions in the CNS compatible with paracoccidioidomycosis.

ABSTRACT

La histoplasmosis y la leishmaniasis son enfermedades olvidadas, endémicas en Argentina, y generalmente se asocian a inmunocompromiso. Presentamos el caso de un varón de 16 años, inmunocompetente, con histoplasmosis del sistema nervioso central y leishmaniasis cutánea. Inicialmente, el paciente presentó una lesión en la pierna de un mes de evolución seguida de paraparesia leve, diagnosticada como un proceso de desmielinización mediante estudios de imágenes. El cuadro fue tratado con altas dosis de corticoides y en 72 horas evolucionó a paraparesia grave con lesiones nodulares en las vértebras cervicales, observadas en las imágenes de resonancia magnética nuclear. Se aisló Histoplasma capsulatum de líquido cefalorraquídeo, genotípicamente identificado como perteneciente a la especie filogenética LamB. El paciente recibió tratamiento intravenoso con anfotericina B deoxicolato durante 30 días y posteriormente fluconazol e itraconazol oral durante un año. A los tres meses de iniciado el tratamiento con antifúngicos se reactivó la lesión de la pierna y en el examen directo se observaron amastigotes de Leishmania. La leishmaniasis cutánea fue tratada con antimoniato de meglumina intramuscular. La respuesta clínica al tratamiento de ambas enfermedades fue favorable.


Histoplasmosis and leishmaniasis are neglected and endemic diseases in Argentina, and generally are found associated with immunosuppression. We report the case of an immunocompetent 16-years-old man with simultaneous occurrence of central nervous system histoplasmosis and cutaneous leishmaniasis. Upon admission, the patient showed a one-month old skin lesion in a leg and mild paraparesis. Imaging studies detected thickening and edema in the spinal cord and the cerebrospinal fluid analysis was within normal range. The case was diagnosed as a demyelinating disorder and treated with high-dose short-term steroids. Seventy-two hours later the patient showed severe paraparesis and nuclear magnetic resonance imaging revealed nodular lesions in the spinal cord. Histoplasma capsulatum belonging to the phylogenetic species LamB was isolated from cerebrospinal fluid samples. The patient received intravenous antifungal therapy with amphotericin B for 30 days, followed by oral fluconazole and itraconazole for one year. Three months after initiation of antifungal treatment, the cutaneous lesion recrudesced and Leishmania amastigotes were observed on microscopic examination. The cutaneous leishmaniasis was treated with intramuscular meglumine antimoniate. The patient´s outcome was favorable after treatment for both diseases.

ABSTRACT

ABSTRACT CONTEXT: Central nervous system (CNS) infectious diseases have high prevalence in developing countries and their proper diagnosis and treatment are very important for public health planning. Cryptococcus neoformans is a fungus that may cause several CNS manifestations, especially in immunocompromised patients. Cryptococcal meningitis is the most common type of involvement. Mass-effect lesions are uncommon: they are described as cryptococcomas and their prevalence is even lower among immunocompetent patients. The aim here was to report an extremely rare case of cryptococcoma causing a mass effect and mimicking a brain tumor in an immunocompetent patient. The literature on CNS cryptococcal infections was reviewed with emphasis on cryptococcomas. Clinical, surgical and radiological data on a female patient with this rare presentation of cryptococcoma mimicking a brain tumor are described. Case Report: A 54-year-old female patient presented to the emergency department with a rapid-onset progressive history of confusion and completely dependency for basic activities. Neuroimaging showed a left occipital lesion and neurosurgical treatment was proposed. From histopathological evaluation, a diagnosis of cryptococcoma was established. She received clinical support with antifungals, but despite optimal clinical treatment, her condition evolved to death. CONCLUSIONS: Cryptococcal infections have several forms of presentation and, in immunocompetent patients, their manifestation may be even more different. Cryptococcoma is an extremely rare presentation in which proper surgical and clinical treatment should be instituted as quickly as possible, but even so, there is a high mortality rate.

ABSTRACT

Introduction Paracoccidioidomycosis (PCM) is a systemic mycosis caused by the fungus Paracoccidioides brasiliensis, and it can compromise the central nervous system (CNS) in 10­27% of all cases. Case Report A 31-year-old man presented to the Emergency Department with headache, left-sided weakness, clonus at the ankle and a positive Babinski sign. Head computed tomography (CT) and magnetic resonance imaging (MRI) scans showed a 5.1 3.8 cm lobulated lesion with areas of liquefaction in the right centrum semiovale. Discussion Central nervous system PCM can mimic a brain tumor, and most cases are diagnosed by biopsy of the lesion. The treatment includes antibiotics, but some cases require surgery. Conclusion Due to high morbimortality rates, the diagnosis must be considered, and early treatment started in patients who live in rural regions endemic for PCM when a ring-enhancing mass associated with perilesional edema is observed on MRI scans.


Introdução Paracoccidioidomicose (PCM) é uma micose sistêmica causada pelo fungo Paracoccidioides brasiliensis e que pode comprometer o sistema nervoso central (SNC) em 10­27% dos casos. Relato de caso Um homem de 31 anos é admitido no pronto socorro com cefaleia, hemiparesia esquerda com clonus e presença de sinal de Babinski. As imagens da tomografia computadorizada (TC) de crânio e da ressonância nuclear magnética (RNM) demonstraram uma lesão de 5,1 3,8 cm no centro semioval direito de aspecto lobulado com áreas de liquefação no centro semioval direito. Discussão Paracoccidioidomicose do SNC pode simular um tumor cerebral, sendo a maioria dos casos diagnosticada por biopsia da lesão. O tratamento inclui antibióticos, mas alguns casos necessitam de abordagem cirúrgica. Conclusão Devido à alta morbimortalidade, o diagnóstico deve ser considerado e o tratamento precoce iniciado em pacientes que vivem em áreas rurais endêmicas para PCM e que apresentam lesão com captação anelar de contraste associada a edema perilesional nas imagens de RNM.

ABSTRACT

La criptococosis es la micosis sistémica más frecuente entre los pacientes con HIV SIDA. Su prevalencia oscila entre el 5% y el 25%, de acuerdo con la región geográfica que se considere. La localización habitual de esta micosis en el paciente VIH es el sistema nervioso central (SNC). La diseminación sanguínea del agente causal ocurre ante defectos de la inmunidad mediada por células, asociándose con frecuencia a linfomas, leucemia, enfermedades del sistema retículo endotelial. A partir de la eclosión del HIV se redujo un aumento significativo del número de casos, transformándose esta última condición en la causa favorecedora más importante.


Cryptococcosis is the most frequent systemic mycosis among patients with HIV AIDS. Its prevalence ranges between 5% and 25%, according to the geographical region considered. The usual location of this mycosis in the HIV patient is the central nervous system (CNS). Blood dissemination of the causative agent occurs due to defects of cell-mediated immunity, frequently associated with lymphomas, leukemia, reticuloendothelial system diseases. From the emergence of HIV, there was a significant increase in the number of cases, with the latter condition becoming the most important favorable cause

ABSTRACT

A criptococose é uma micose sistêmica, de ocorrência relativamente rara, potencialmente grave, geralmente oportunista e de elevada frequência em pacientes imunossuprimidos, com amplo espectro de acometimento de órgãos, tropismo especial para o sistema nervoso central (SNC), evolução subaguda ou crônica, e manifestações clínicas variadas. Este estudo descritivo, retrospectivo, observacional, transversal, objetivou descrever os dados demográficos, clínicos, comorbidades, sintomas ou sinais, e o prognóstico de pacientes com neurocriptococose, atendidos e internados no Hospital das Clínicas (HC) da Universidade Federal de Minas Gerais desde 2000 até 2013. O HC é unidade universitária, pública e geral, de nível terciário e quaternário, com 450 leitos de internação, integrado ao Sistema Único de Saúde (SUS), com clientela universalizada, cerca de 40% do total proveniente do interior do estado de Minas Gerais, predominando da região Metropolitana de Belo Horizonte, aberto à transferência de pacientes de todo o território mineiro, com área de abrangência de população de mais de cinco milhões de pessoas, de todas as faixas etárias e todas as especialidades médicas, encaminhados pela intensidade de sua expressão clínica, especialmente em situação crítica, o que torna sua casuísticade máxima gravidade. Os pacientes foram internados a partir do Pronto Socorro do HC que admite, em média, 80 pacientes com urgência clínicas por dia, incluindo obstétricas, e excluídas aquelas devido à acidente ou violência de qualquer natureza. Foram analisados 40 pacientes com neurocriptococose o que significou 0,13% de toda demanda de admissão de urgência para o período estudado, cerca de 603.000 pessoas, isto é 12% da população referida, e associou-se à letalidade de 25%; com frequência da distribuição de acordo com o gênero em 2:1, entre homens e mulheres, respectivamente; e nas faixas etárias entre 20-40, 40-60 e mais de 60 anos de idade, de 36%, 42%, e 22%, respectivamente, sendo a proporção entre 20 a 60 e mais de 60 de aproximadamente, 2:1. A neurocriptococose associou-se em mais de 50% dos pacientes com a: SIDA (57,5%); internação prévia (52,5%) relacionada à quimio e corticoterapia, transplante, cirurgias para ressecção de neoplasias; e, em menos de 20% com doença cardiovascular hipertensiva sistêmica (17,5%), cirurgia prévia (15%) e tuberculose (5%). A sintomatologia isolada presente em pelo menos 40% dos pacientes foi: cefaleia (70%), astenia (50%), febre (45%), vômitos (40%); entretanto, em até um terço deles constituiu-se de: emagrecimento (30%), tontura (30%), dor abdominal (27,5%), convulsão (22,5%). As anormalidades mais e menos especificamente indicadoras de acometimento do SNC foram cefaleia; e, vômito, tontura e convulsão,respectivamente. As alterações do exame neurológico foram relacionadas aos distúrbios da consciência (35%), lesão focal (30%), alteração da marcha (25%) e distúrbio do comportamento (15%). A concomitância de cefaléia, convulsão e vômitos foi anotada em 5% dos pacientes; enquanto de cefaléia e convulsão em 22,5%. Foi observada, à admissão hospitalar, em 40%, dos pacientes a associação de cefaléia e vômito; mas todos os pacientes com vômito e também os com lesão focal apresentavam cefaleia. A presença de cefaleia não foi descrita em 35% dos pacientes com alteração da consciência à admissão hospitalar. O diagnóstico presuntivo de neurocriptococose deve ser realizado, independentemente da sintomatologia clínica neurológica, o que realça a percepção geral do paciente, incluindo epidemiologia, história familiar, história prévia, manifestações clínicas, presença de imunossupressão, para surpreender a criptococose, e iniciar a terapêutica o mais apidamente possível para que possa ser reduzida sua letalidade. A limitação deste estudo relaciona-se ao fato de ter sido retrospectivo, em que o controle dos dados registrados é muito limitada, sendo impossível corrigir a ausência de dados registrados. (AU)


Cryptococcosis is a systemic, relatively rare, potentially severe, often opportunistic and systemic mycosis in immunosuppressed patients with a broad spectrum of organ involvement, a special central nervous system (CNS) tropism, subacute or chronic clinical manifestations. This descriptive, retrospective, observational, cross-sectional study aimed to describe the demographic, clinical, comorbidities, symptoms or signs, and the prognosis of patients with neurocryptococcosis, attended and hospitalized at the Hospital das Clínicas (HC) of the Universidade Federal de Minas Gerais since 2000 until 2013. The HC is a university unit, public and general, tertiary and quaternary level, with 450 beds of hospitalization, integrated into the Unified Health System (SUS), with a universalized clientele, about 40% of the total coming from the interior of the state of Minas Gerais, predominating in the metropolitan region of Belo Horizonte, which is open to the transfer of patients from all over Minas Gerais, with an area of population of more than five million people, of all age groups and all medical specialties. intensity of its clinical expression, especially in a critical situation, which makes its series of age.The patients were hospitalized from the HC Emergency Room, which admitted, on average, 80 urgently needed clinics per day, including obstetrics, and excluded due to accidents or violence of any kind. We analyzed 40 patients with neurocryptococcosis, which represented 0.13% of all urgent admission demands for the period studied, about 603,000 people, ie 12% of the referred population, and was associated with a 25% lethality; with frequency of distribution according to gender in 2: 1, between men and women, respectively; and in the age groups between 20-40, 40-60 and over 60 years of age, of 36%, 42%, and 22% respectively, the ratio being between 20 to 60 and more than 60 of approximately 2: 1. Neurocryptococcosis was associated in more than 50% of patients with: AIDS (57.5%); previous hospitalization (52.5%) related to chemo and corticoid therapy, transplantation, surgeries for resection of neoplasias; and in less than 20% with systemic hypertensive cardiovascular disease (17.5%), previous surgery (15%) and tuberculosis (5%). The isolated symptoms present in at least 40% of the patients were: headache (70%), asthenia (50%), fever (45%), vomiting (40%); (30%), dizziness (30%), abdominal pain (27.5%), and seizure (22.5%). The most and least specific abnormalities of CNS involvement were headache; and, vomiting, dizziness and convulsion, respectively. Changes in neurological examination were related to disturbances of consciousness (35%), focal lesion (30%), gait alteration (25%) and behavior disorder (15%). The concomitance of headache, convulsion and vomiting was noted in 5% of the patients; while headache and seizure in 22.5%. The association of headache and vomiting was observed in 40% of patients; but all patients with vomiting and those with focal lesion also had headache. The presence of headache was not described in 35% of patients with altered consciousness at hospital admission. The presumptive diagnosis of neurocryptococcosis should be performed independently of the clinical neurological symptomatology, which highlights the general perception of the patient, including epidemiology, family history, previous history, clinical manifestations, presence of immunosuppression, to start cryptococcosis, and initiate therapy. as soon as possible so that their lethality can be reduced. The limitation of this study is the fact that it was retrospective, in which the control of the recorded data is very limited, and it is impossible to correct the absence of recorded data. (AU)

ABSTRACT

Rhino-orbito-cerebral mucormycosis is an aggressive and potentially lethal invasive fungal infection. Surgical debridement and amphotericin B remain the mainstay of treatment, however, associated side effects of amphotericin B like nephrotoxicity, hypokalemia, hypertension and arrhythmias need to be addressed. We discuss the anesthetic management of a 47 year old male with uncontrolled diabetes diagnosed with left sinoorbital mucormycosis posted for surgical debridement. The patient received amphotericin B and insulin preoperatively. Nephrotoxicity due to amphotericin B led to hypokalemia in this patient. We also discuss the role of liposomal formulation in preventing hypokalemia and other side effects associated with use of amphotericin

ABSTRACT

Paracoccidioidomycosis and histoplasmosis are systemic fungal infections endemic in Brazil. Disseminated clinical forms are uncommon in immunocompetent individuals. We describe two HIV-negative patients with disseminated fungal infections, paracoccidioidomycosis and histoplasmosis, who were diagnosed by biopsies of suprarenal lesions. Both were treated for a prolonged period with oral antifungal agents, and both showed favorable outcomes.


A paracoccidioidomicose e a histoplasmose são infecções fúngicas sistêmicas endêmicas no Brasil. As formas clínicas disseminadas são incomuns em pacientes imunocompetentes. Nós descrevemos dois pacientes HIV-negativos com infecções fúngicas disseminadas, paracoccidioidomicose e histoplasmose, que foram diagnosticadas por biópsias de lesões de supra-renal. Ambos foram tratados por períodos prolongados com antifúngicos orais, evoluindo com boa resposta terapêutica.

ABSTRACT

SUMMARYConsidered to be an emerging endemic mycosis in Latin America, paracoccidioidomycosis is characterized by a chronic course and involvement of multiple organs in immunocompromised hosts. Infection sequelae are mainly related to pulmonary and adrenal insufficiency. The host-parasite interaction results in different expressions of the immune response depending on parasite pathogenicity, fungal load and genetic characteristics of the host. A few controlled and case series reports have shown that azoles and fast-acting sulfa derivatives are useful treatment alternatives in milder forms of the disease. For moderate/severe cases, more prolonged treatments or even parenteral routes are required especially when there is involvement of the digestive tract mucosa, resulting in poor drug absorption. Although comparative studies have reported that shorter treatment regimens with itraconazole are able to induce cure in chronically-infected patients, there are still treatment challenges such as the need for more controlled studies involving acute cases, the search for new drugs and combinations, and the search for compounds capable of modulating the immune response in severe cases as well as the paradoxical reactions.


RESUMOConsiderada micose endêmica emergente na América Latina, a paracoccidioidomicose é caracterizada por uma evolução crônica e envolvimento de múltiplos órgãos em pacientes com comprometimento imunológico. Sequelas da infecção estão relacionadas principalmente à insuficiência pulmonar e adrenal. A interação hospedeiro-parasito resulta em diferentes expressões da resposta imune dependendo da patogenicidade do parasito, carga fúngica e características genéticas do hospedeiro. Alguns estudos controlados e séries de casos têm demonstrado que azóis de ação rápida e derivados de sulfa constituem alternativas terapêuticas úteis nas formas mais leves da doença. Para casos moderados/graves, tratamentos mais prolongados ou mesmo por via parenteral são necessários especialmente quando há envolvimento de mucosa do trato digestivo, resultando em absorção deficiente de drogas. Embora estudos comparativos tenham relatado que esquemas terapêuticos mais curtos com itraconazol sejam capazes de induzir cura em pacientes cronicamente infectados, ainda existem desafios no tratamento, tais como a necessidade de maior número de estudos controlados envolvendo casos agudos, busca por novas drogas e combinações, compostos capazes de modular a resposta imune nos casos graves, e reações paradoxais.

ABSTRACT

<p><b>OBJECTIVE</b>To study the clinical value of cranial magnetic resonance imaging (MRI) in the diagnosis and treatment of central nervous system candidiasis (CNSC), which has no specific clinical manifestations and has no rapid and specific diagnostic tools.</p><p><b>METHODS</b>A retrospective analysis was performed on the clinical data of 10 children who were diagnosed with CNSC in Beijing Children's Hospital Affiliated to Capital Medical University between 2009 and 2013.</p><p><b>RESULTS</b>Nine of the 10 children underwent cranial MRI within 8 days after admission, and 5 of the 9 children underwent contrast-enhanced MRI at the same time. Eight of the 9 children showed the features of meningoencephalitis, and 6 cases were accompanied by varying degrees of brain atrophy; one case showed hydrocephalus and cerebral abscess, and another case showed leukoencephalopathy. Six cases were found to have the features of cerebral vasculitis after infection in the first MRI after admission, including cerebral infarction (2 cases), venous sinus thrombosis (3 cases), and Moyamoya disease (1 case). Infectious granulomatous lesions were confirmed by contrast-enhanced MRI in 3 cases. Given the clinical manifestations, 8 of the 9 cases were diagnosed as suspected CNSC after MRI, and 7 of these cases received antifungal therapy before the pathogen test results were returned. The lesions on MRI were improved in 6 cases after 3-4 weeks of antifungal treatment. All the 10 children were diagnosed with CNSC by positive cerebrospinal fluid culture results.</p><p><b>CONCLUSIONS</b>Cranial MRI, especially contrast-enhanced MRI, is of great significance for the diagnosis and treatment of CNSC. To confirm the guidance of MRI in the diagnosis and treatment of CNSC, further case-control studies are needed.</p>

ABSTRACT

OBJECTIVE@#To study the clinical characteristics of invasive fungal infection secondary to systemic lupus erythematosus (SLE).@*METHODS@#We observed the clinical features and experimental examination in 91 patients treated in Xiangya Hospital in recent years, of which 48 patients with invasive fungal infection and 41 patients without invasive fungal infection.@*RESULTS@#The invasive fungal infection secondary to SLE mainly occurred in the lungs, nervous system, and urinary system. The fungi were mainly Candida albins and Aspergillus. The rate of invasive fungal infection in SLE patients and the level of CRP and TNF-α in these patients were significantly increased. The occurrence of invasive fungal infection was positively correlated with the prolonged course of disease, long-term use of immunosuppressants and antibiotics, and occurrence of complications, such as hypoproteinemia, leukocytopenia, and so on. The levels of C-reactive protein (CRP) and tumor necrosis factor-α(TNF-α) were increased in SLE patients with invasive fungal infection.@*CONCLUSION@#The clinical features of SLE patients with invasive fungal infections are long course of disease, long-time use of immunosuppressants or antibiotics, and occurrence of complications, such as hypoproteinemia or leukopenia. The level of CRP and TNF-α can be used as an important reference index for diagnosing invasive fungal infections.

The purpose of this study was to determine the microbiological air quality (psychrotrophic bacteria and airborne fungi) and distribution of fungi in different types of ready-to-eat (RTE) food-storage refrigerators (n=48) at selected retail stores in the city of Edirne, Turkey. Refrigerators were categorized according to the type of RTE food-storage: meat products, vegetables, desserts, or a mix of food types. Microbiological quality of air samples was evaluated by using a Mas-100 Eco Air Sampler. Four refrigerators (all containing meat products, 8.3%) produced air samples with undetectable microorganisms. The highest detected mean value of airborne psychrotrophic bacteria and fungi was 82.3 CFU/m³ and 54.6 CFU/m³, respectively and were found in mixed-food refrigerators. The dominant airborne fungal genera found were Penicillium (29.0%), Aspergillus (12.0%), Mucor (9%), Cladosporium (8%), Botyrtis (7%), and Acremonium (6%). By definition, RTE food does not undergo a final treatment to ensure its safety prior to consumption. Therefore, ensuring a clean storage environment for these foods is important to prevent food-borne disease and other health risks.

ABSTRACT

The goal of this study was to review 18 cases of phaeohyphomycosis in Rio Grande do Sul. The records of all of the patients with a diagnosis of phaeohyphomycosis between 1995-2010 were reviewed. Twelve of the 18 patients (66.6%) were male. The average age of the patients was 50 years old (range: 16-74 years). Eleven patients (61%) presented with subcutaneous lesions. Seven patients (38.8%) had received a solid organ transplant. In all of the cases, the presence of melanin in the fungal cells was determined by Fontana-Masson staining of tissue sections and documented. Among the 18 patients, a total of 11 different fungal species were isolated. The causative organisms included Exophiala jeanselmei, Alternaria, Curvularia, Cladophialophora and Colletotrichum gloeosporioides. To our knowledge, this review reports the first case of subcutaneous phaeohyphomycosis caused by C. gloeosporioides in a lung transplant patient. The number of reported cases of phaeohyphomycosis has increased in the last decade. In a number of cases, this increased incidence may be primarily attributed to iatrogenic immunodeficiency.

ABSTRACT

INTRODUCTION: Paracoccidioidomycosis (PCM) is the most important systemic mycosis in South America. Central nervous system involvement is potentially fatal and can occur in 12.5% of cases. This paper aims to contribute to the literature describing eight cases of neuroparacoccidioidomycosis (NPMC) and compare their characteristics with patients without neurological involvement, to identify unique characteristics of NPCM. METHODS: A cohort of 213 PCM cases was evaluated at the Infectious Diseases Clinic of the University Hospital, Federal University of Minas Gerais, Brazil, from October 1976 to August 2008. Epidemiological, clinical, laboratory, therapeutic and follow-up data were registered. RESULTS: Eight patients presented NPCM. The observed NPCM prevalence was 3.8%. One patient presented the subacute form of PCM and the other seven presented the chronic form of the disease. The parenchymatous form of NPCM occurred in all patients. 60% of the patients who proceeded from the north/ northeast region of Minas Gerais State developed NPCM. The neurological involvement of a mother and her son was observed. NPCM patients exhibited demographical and clinical profiles similar to what is described in the literature. When NPCM cases were compared to PCM patients, there were differences in relation to origin and positive PCM family history. CONCLUSIONS: The results corroborate the clinical view that the neurological findings are extremely important in the evaluation of PCM patients. Despite the limitations of this study, the differences in relation to patient's origins and family history point to the need of further studies to determine the susceptibility factors involved in the neurological compromise.


INTRODUÇÃO: A paracoccidioidomicose (PCM) é a micose profunda mais importante na América do Sul. O comprometimento do sistema nervoso central é grave e pode ocorrer em 12,5% dos casos. Este trabalho tem como objetivo descrever oito casos de neuroparacoccidioidomicose (NPMC) e comparar suas características com pacientes sem envolvimento neurológico, a fim de identificar aspectos singulares da NPCM. MÉTODOS: Uma coorte de 213 casos de PCM foi avaliada na Clínica de Doenças Infecciosas do Hospital das Clínicas da Universidade Federal de Minas Gerais, de outubro de 1976 a agosto de 2008. Dados epidemiológicos, clínicos, laboratoriais, terapêuticos e de seguimento foram registrados. RESULTADOS: Oito pacientes apresentaram NPCM. A prevalência de NPCM observada foi de 3,8%. Um paciente apresentou a forma subaguda da PCM e sete apresentaram a forma crônica. Todos os pacientes apresentaram a forma parenquimatosa. Cerca de 60% dos pacientes provenientes das regiões norte e nordeste de Minas Gerais desenvolveram NPCM. Foi observado o desenvolvimento de NPCM em uma mãe e em seu filho. Os pacientes com NPCM apresentaram perfis demográficos e clínicos similares à descrição da literatura. Quando comparados aos pacientes com PCM, houve diferenças em relação à procedência de tais pacientes e história familiar positiva de PCM. CONCLUSÕES: Os resultados confirmam a importância da avaliação neurológica em pacientes com PCM. Apesar das limitações desse trabalho, as diferenças com relação à procedência dos pacientes e à história familiar apontam para a necessidade de mais estudos para investigar a existência de fatores de susceptibilidade envolvidos no desenvolvimento da NPCM.

ABSTRACT

Idiopathic CD4 lymphocytopenia (ICL) is a rare disorder which is often diagnosed as HIV-negative AIDS in the light of poor immunity and AIDS-defining illnesses. We present a case of a 50-year-old male who presented with a midline posterior fossa tumour with ICL diagnosed as cerebellar cryptococcoma.
