ABSTRACT

Resumen La paracoccidioidomicosis es una infección fúngica endémica de América del Sur, que afecta predominantemente a los hombres y, según su campo laboral, granjeros y agricultores. Es ocasionada por la aspiración del hongo en su forma micelar y debuta en tres formas de presentación: aguda, subaguda y crónica; esta última es más frecuente en adultos, cuyo tratamiento dependerá de los azoles, anfotericina B y sulfonamidas. El presente caso trata de un hombre de 57 años, colombiano, agricultor, sin antecedentes patológicos, quien presentaba dos meses de disfagia para sólidos que progresó a líquidos, sialorrea y pérdida de peso, a quien se le realizó endoscopia de vías digestivas altas y se observaron lesiones blanquecinas, por lo cual se realizó una biopsia que evidenció levaduras en múltiple gemación compatibles con paracoccidioidomicosis; a su vez, se observó en una tomografía de tórax compromiso parenquimatoso intersticial generalizado; posteriormente, recibió tratamiento con itraconazol, con el que mostró mejoría y resolución del cuadro clínico. En vista de que América del Sur es endémica de la patología descrita y puede presentarse de forma diseminada en inmunocompetentes, se debe tener en cuenta en aquellos pacientes que poseen factores de riesgo, sintomatología y hallazgos en estudios de extensión sugestivos de dicha enfermedad, dado el gran espectro de presentación de la infección, para así dar tratamiento oportuno y dirigido.


Abstract Paracoccidioidomycosis (PCM) is a fungal infection endemic to South America. It predominantly affects men, depending on their work field: farmers and agriculturists. Paracoccidioidomycosis is caused by the aspiration of the fungus in its micellar form and manifests in three conditions: acute, subacute, and chronic; the latter is more frequent in adults, whose treatment will depend on azoles, amphotericin B, and sulfonamides. This case concerns a 57-year-old Colombian man, a farmer with no pathological history who showed dysphagia for solids that progressed to liquids, sialorrhea, and weight loss for two months. He underwent upper GI endoscopy, and whitish lesions were observed; thus, he was biopsied, displaying yeasts in multiple gemmations compatible with paracoccidioidomycosis. In turn, a chest CT scan showed generalized interstitial parenchymal involvement. Subsequently, he was treated with itraconazole, showing improvement and resolution in his clinical picture. Since the pathology described is endemic in South America and can be disseminated in immunocompromised patients. Given the broad infection spectrum, consideration should be given to patients with risk factors, symptomatology, and findings in extension studies suggesting this disease to provide timely and specific treatment.

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

OBJECTIVES: Imported systemic mycoses is a severe fungal infection that can cause diseases in healthy people. However, there is a serious lack of epidemiological data about imported systemic mycoses. Therefore, an epidemiological characterization of imported systemic mycoses in Korea was performed. METHODS: We collected health insurance data between 2008 and 2012 from the Health Insurance Corporation and analyzed the data to determine the prevalence and treatment management of imported systemic mycoses. RESULTS: The prevalence of imported systemic mycoses between 2008 and 2012 increased slowly by 0.49/100,000 to 0.53/100,000 persons. The prevalence of coccidioidomycosis increased from 0.28/100,000 in 2008 to 0.36/100,000 persons in 2012. A mean of 229.6 cases occurred each year. Children and the elderly showed higher prevalence than adults in the 20- to 59-year-old age group. The rate of infection according to region ranged from 0.18/100,000 persons in Ulsan, to 0.59/100,000 persons in Gyeonggi. The prevalence in females was higher than that in males. Inpatient treatment was 3.3% (38 cases), with 96.7% treated as outpatients. Hospitalizations cost 272.7 million won and outpatient treatments cost 111.7 million won. The treatment cost for coccidioidomycosis from 2008 to 2012 was 330.9 million won, with personal charges of 79.2 million won and insurance charges of 251.7 million won. Most of the expenses for the coccidioidomycosis treatment were for inpatient treatment. CONCLUSION: The results in this study may be a useful resource for determining the changes in the trend of imported systemic mycoses.

ABSTRACT

AbstractJorge Lobo's Disease is a rare, chronic granulomatous cutaneous mycosis, which is typical of tropical and subtropical regions. It is caused by the traumatic implantation of the fungus Lacazia loboi into the skin and subcutaneous tissue. The disease was first described in 1931 by Jorge Lobo, in Recife (PE), Brazil. It is common in Central and South America, and predominates in the Amazon region. We report a case of Jorge Lobo's Disease, which had been initially referred as being paracoccidioidomycosis. We emphasize clinical and diagnostic features of the disease.

ABSTRACT

A case of pulmonary blastomycosis on autopsy in a middle aged male from rural background is presented herewith. Blastomycosis is a pyogranulomatous disease caused by the dimorphic fungus blastomyces dermatitidis. Blastomycosis is endemic in regions of North America that border the Great Lakes. It is one of the great mimickers in medicine. Pulmonary blastomycosis has a broad range of clinical presentations, varying from completely asymptomatic pulmonary infiltrates to diffuse and massive parenchymal involvement that can lead to Acute Respiratory Distress Syndrome (ARDS). Human infection occurs when soil containing microfoci of mycelia is distributed and airborne conidia are inhaled. If natural defences in the alveoli fail to contain the infection, lymphohematogenous dissemination ensues. Diagnosis is based on culture and direct visualization of round, multinucleated yeast forms that produce daughter cells from a single broad- based bud. Most of the cases of blastomycosis reported in India are imported from the endemic areas of the World except a few authochthonous cases in North India.

ABSTRACT

A Doença de Jorge Lobo é uma micose subcutânea que tem como agente etiológico o fungo Paracoccidioides loboi. Este fungo pode infectar tanto humanos quanto golfinhos. O primeiro caso em humanos foi registrado no Brasil em 1931. A história natural da doença se inicia pela instalação do microorganismo nos tecidos subcutâneos e as lesões são nodulares, isoladas, com aspecto queloideano, acometendo principalmente o pavilhão auricular e os membros inferiores e superiores. Geograficamente, esta micose ocorre mais em regiões de florestas densas, quentes e úmidas. O presente artigo teve por objetivo mostrar as características da doença em homens e em golfinhos.


Jorge Lobo's disease is a subcutaneous mycosis caused by the Paracoccidioides loboi, which can infect both humans and dolphins. The first case in humans was described in Brazil, in 1931. The disease´s natural history initiates after the infection by the microorganism. The lesions are solitary nodular keloid-looking that arises, mainly, in the ear and in the upper and lower limbs. Geographically, this mycosis shows itself in dense, hot and humid forest regions. This article aimed the presentation of the disease in humans and dolphins.

ABSTRACT

TEMA: identificar as alterações morfofuncionais decorrentes de quinze anos de obstrução nasal total em um caso de sinéquia de palato mole e paredes faríngeas pós blastomicose. PROCEDIMENTOS: o trabalho foi baseado no estudo de caso de um adulto do gênero feminino, de 26 anos de idade, que chegou a um centro especializado em deformidades craniofaciais, com a queixa de não conseguir respirar pelo nariz. Sua dificuldade respiratória é decorrente de uma aderência total do palato mole com as paredes faríngeas, como sequela da blastomicose que teve no palato aos 11 anos de idade. RESULTADOS: na entrevista, a paciente relatou queixa de cefaléia, halitose, pouco rendimento físico, sonolência diurna e sono agitado durante a noite. Referiu também anosmia, mastigação lenta e engasgos frequentes. Durante a avaliação, observou-se respiração exclusivamente oral do tipo superior, mastigação bilateral alternada e lenta, deglutição adaptada e ressonância hiponasal de grau grave. Observou-se ainda face longa, perfil convexo, mandíbula retruída e olheiras. Os lábios da paciente encontravam-se entreabertos e ressecados, sendo o superior fino e o inferior evertido e avolumado e o palato duro apresenta-se atrésico, estreito e profundo. CONCLUSÃO: as características da paciente em questão são compatíveis com a Síndrome do Respirador Oral e pode-se supor que sejam consequências morfofuncionais de uma obstrução nasal total.


BACKGROUND: to identify the consequences that arising from fifteen years of total nasal obstruction in a case of post blastomicose palato and pharynx's lesion. PROCEDURES: this article was based on a case report of a 26-years-old female subject, who came to a specialized center on craniofacial deformities, complaining about her mouth breathing. Her respiratory difficulty stems from a total tack of palate and pharynx, as a blastomicose sequel that she had when 11-year-old. RESULTS: during the interview, the patient said that she had poor physical conditioning, daytime sleepiness, slow chewing and choking during the swallowing process. At evaluation, it was noted exclusive oral breath of the superior type, alternate chew on both sides, adapted swallowing and serious hyponasal resonance. we also noted long face, with convex profile, retruded jaw and dark circles under the eyes. Her lips were half-opened and dried up, with the upper one thinner and the lower part turned round and augmented. The patient's palate is atresic, strait and deep. CONCLUSION: the patient's characteristics are compatible with Oral Breath Syndrome and anatomic-functional consequences of a total nasal obstruction.

ABSTRACT

El compromiso esofágico es una complicación infrecuente de la tuberculosis incluso en países con alta prevalencia de infección. Se presenta el caso de un paciente de 57 años no seropositivo al virus de inmunodeficiencia humana (VIH), con diagnóstico simultáneo de blastomicosis en cavidad oral y papilomatosis laríngea, ambas confirmadas por anatomía patológica. La biopsia de esófago reveló esofagitis granulomatosa con necrosis; la tinción de Ziehl-Neelsen mostró bacilos ácido-alcohol resistente, sugerentes de tuberculosis. El antecedente de tuberculosis pulmonar en dos oportunidades y abandono de tratamiento determinó el inicio de tratamiento antituberculoso de segunda línea a través de un tubo de gastrostomía, más itraconazol vía oral. La evolución fue favorable.


Esophageal involvement is an extremely rare complication of tuberculosis even in countries with high prevalence of infection. We report the case of a 57 year-old hiv-seronegative patient with simultaneous diagnoses of oral blastomycosis and laryngeal papillomatosis. Both were confirmed by anatomopathological analysis. The esophageal biopsy revealed granulomatous esophagitis with necrosis and ziehl-neelsen stain showed acid-fast alcohol resistant bacilli suggestive of tuberculosis. The patient’s history included pulmonary tuberculosis twice and previous abandonment of therapy. Thus, it was necessary to use oral itraconazole combined with second-line anti-tuberculosis drugs administered through a gastrostomy tube. The clinical development was favorable.

ABSTRACT

Blastomycosis, endemic in North America, has been hardly reported in Korea. We describe laboratory experience in phenotypic and molecular identification of Blastomyces dermatitidis first isolated in Korea. The patient was a 45-year-old male with pulmonary blastomycosis mimicking pulmonary tuberculosis. Diagnosis was based on culture and dimorphism combined with DNA target sequencing of internal transcribed spacers (ITS) and D1/D2 regions.

ABSTRACT

Blastomyces dermatitidis is a dimorphic fungus that causes the systemic pyogranulomatous disease known as blastomycosis. Blastomycosis most often involves the lungs, skin, and may involve nearly every organ in the body. It is difficult, however, to diagnose blastomycosis in the early stage of pulmonary disease because clinical manifestations are varied from subclinical infection to acute respiratory distress syndrome. Since blastomycosis is often accompanied by granulomatous inflammation in histopathologic findings, differentiation from other etiologic diseases is important. We report a case of a 45-year-old male with pulmonary blastomycosis who had been misdiagnosed with tuberculosis for 3 months.

ABSTRACT

Doença de Jorge Lobo (DJL) é infecção granulomatosa cutânea crônica produzida pelo fungo Lacazia loboi, cujas lesões mais típicas têm aspecto queloidiano, com localizações preferenciais em membros e orelhas. As lesões restringem-se à pele, havendo apenas uma referência, do conhecimento dos autores, à localização em semimucosa labial. Apresenta-se caso de doença de Jorge Lobo em paciente masculino, com lesão papulonodular no vermelhão do lábio superior, à esquerda, de dez anos de evolução, exitosamente submetida a tratamento cirúrgico, sem recidiva após oito anos.


Jorge Lobo's Disease (JLD) is a chronic granulomatous cutaneous mycosis caused by Lacazia loboi. The most typical lesions are keloid-like growths preferentially located on limbs and ears. To the best of the authors' knowledge, only one labial case has previously been reported. We describe the case of a man who presented with a left-sided papulonodular lesion of 10 years' duration on the vermillion border of the upper lip. A successful surgical resection of the lesion was performed and there was no recurrence in eight years of follow-up.

ABSTRACT

Objective To evaluate the performance of nested PCR in the detection of different fungi in paraffin wax embedded tissues. Methods Forty-four tissue samples were resected from rats infected with Fonsecaea monophora, patients with chromoblastomycosis, sporotrichosis or penicilliposis marneffei followed by preparation of paraffin wax embedded tissue sections for pathological examination and DNA extraction. Nested PCR was performed by using specific primers targeting the ribosomal DNA of Fonsecaea, Sporothrix and Penicillium marneffei, respectively. The sensitivity and specificity of nested PCR were analyzed and compared with those of pathological examination. Results The nested PCR showed positive results in 8 of 20 samples from rats with chromoblastomycosis, 7 of 10 samples from patients with sporotrichosis and all of the 10 samples from patients with penicilliposis marneffei, but not in the control samples. In the detection of Fonsecaea,Sporothrix schenki and Penicillium marneffei, the sensitivity was 40% ,70% and 100%, respectively, and the specificity was consistently 100%, for the nested PCR. Pathological examination revealed fungal elements in 95%, 70% and 80% of the corresponding samples, respectively. Conclusion Detection of fungal DNA in paraffin wax embedded tissue by nested PCR can be applied to the diagnosis of deep mycosis, especially to the diagnosis of penicilliposis marneffei.
