    Blastomycosis is a fungal disease that is endemic in parts of North America.It is very rare in China and also commonly misdiagnosed,often as cancer or other infectious diseases.The clinical profile of a case of disseminated blastomycosis with pulmonary changes and skin ulcers was described.He had been misdiagnosed with tuberculosis,after adequate therapy with a lipid formulation of amphotericin B,followed by itraconazole,the lung and skin lesions improved.Then the five cases reported in China and literatures were reviewed.The aim of this report was to improve the knowledge regarding blastomycosis for physicians in China to avoid delaying adequate therapy.

  5. Blastomycosis presenting as solitary nodule: A rare presentation

    Directory of Open Access Journals (Sweden)

    Ashish Dhamija


    Full Text Available Blastomycosis is a chronic granulomatous and suppurative mycosis, caused by Blastomyces dermatitidis, which in the great majority of cases presents as a primary pulmonary disease. Primary cutaneous blastomycosis is very rare. We present a 57-year-old female patient with a solitary, slowly progressive nodule over upper lip of 2½ months duration. Initially, differential diagnosis of cutaneous leishmaniasis, pyoderma and deep mycoses were entertained. Slit smear preparation was suspicious of deep mycotic infection which was subsequently confirmed by biopsy and culture.

  6. Cutaneous blastomycosis and dermatophytic pseudomycetoma in a Persian cat from Bangkok, Thailand. (United States)

    Duangkaew, Lerpen; Larsuprom, Lawan; Kasondorkbua, Chaiyan; Chen, Charles; Chindamporn, Ariya


    This is a case report of concurrent of blastomycosis and pseudomycetoma in a 3 year-old Persian cat from Bangkok, Thailand. Histopathology from antemortem and postmortem samples revealed blastomycosis and dermatophyte pseudomycetoma. The PCR analysis of the formalin-embedded tissue of antemortem sample confirmed that blastomycosis was caused by Blastomyces dermatitidis. Dermatophyte infection was caused by Microsporum canis. According to the author's knowledge, this is the first case of Blastomyces dermatitidis and dermatophyte pseudomycetoma in South-East Asia.

  7. Pulmonary blastomycosis in a professional diver: An occupational risk

    Directory of Open Access Journals (Sweden)

    Ryan R Kroll


    Full Text Available In certain parts of the United States and Canada, and northern Ontario in particular, the dimorphic fungus Blastomyces dermatitidis is endemic and can cause infection in exposed individuals. The site of infection is usually pulmonary, causing respiratory and constitutional symptoms, but can also affect other sites in the body. Symptom severity can vary substantially from no symptoms to fatal acute respiratory distress syndrome. The present report describes a 27-year-old professional diver who had recently worked in northern Ontario, who developed symptoms of pneumonia and exhibited atypical findings on chest imaging. He was diagnosed with blastomycosis based on histopathological findings and fungal culture, and was treated with amphotericin B and itraconazole in accordance with treatment guidelines. While outdoor occupations in endemic areas increase the risk of infection, there is no literature specifically identifying professional diving as an occupational risk for blastomycosis.

  8. Successful Treatment of Osseous Blastomycosis without Pulmonary or Disseminated Disease and Review of the Literature (United States)

    Day, Shandra R.; Weiss, David B.; Hazen, Kevin C.; Moore, Christopher C.


    Blastomycosis commonly occurs following inhalation of Blastomyces dermatitidis conidia causing a pulmonary infection and can disseminate to extrapulmonary sites. Osseous involvement primarily results from hematogenous spread but in rare cases direct inoculation can occur. We describe a case of osseous blastomycosis without pulmonary or disseminated disease successfully treated with posaconazole. PMID:24703876

    Directory of Open Access Journals (Sweden)

    Jay A Vachhani


    Full Text Available Background: Blastomycosis is a dimorphic fungus that is endemic to the midwest and southwestern United States. Involvement of the central nervous system (CNS is thought to only represent 5-10% of cases of disseminated Blastomycosis. Case Description: A 54-year-old Caucasian female presented to the Neurosurgery service with a 1-day history of progressive right sided hemiparesis. Magnetic resonance imaging (MRI demonstrated a 2 × 4 cm heterogeneous intracranial mass lesion involving the left motor cortex and extending into the ipsilateral parietal lobe. Single-voxel magnetic resonance spectroscopy (MRS over the enhancing area demonstrated diminished N-acetyl aspartate (NAA to creatine ratio (1.10, normal choline to NAA ratio (0.82, normal choline to creatine ratio (0.9, and a diminished myoinositol to creatine ratio (0.39. There appeared to be peaks between 3.6 and 3.8 ppm over the enhancing area that were not present in the contralateral normal brain and thought to represent a "trehalose" peak. Due to worsening symptoms and uncertain preoperative diagnosis, the patient underwent a left fronto-parietal craniotomy for open surgical biopsy with possible resection approximately one month after presentation. Pathological analysis confirmed the diagnosis of Blastomycosis. Conclusion: We present the second documented case of intracranial Blastomycosis with MRS imaging. There appears to be a characteristic peak between 3.6 and 3.8 ppm that is thought to represent a "trehalose" peak. This peak is rather specific to fungi and can be helpful in differentiating fungal abscesses from pyogenic abscesses and malignant neoplasms.

  10. Development of a slide agglutination assay for detection of blastomycosis. (United States)

    Hatch, Wayne O; Scalarone, Gene M


    Blastomycosis, caused by the thermally dimorphic fungus Blastomyces dermatitides, which is endemic to eastern regions of the USA, is commonly misdiagnosed as a viral or bacterial infection and therefore treated improperly. Over the years, many immunodiagnostic assays to aid in the diagnosis of blastomycosis have been developed; however, a reliable assay for use in local clinics still remains elusive. Procedures for a slide agglutination assay for detection of antibody in serum from rabbits immunized with B. dermatitidis were evaluated with antigenic preparations from B. dermatitidis adsorbed to polystyrene microparticles. Yeast-phase lysates from five isolates of B. dermatitides: namely ER-593 (Eagle River, WI, USA), ER-598 (Eagle River, WI, USA), 48938 (India), B5896 (Mt. Iron, MN, USA), and T-58 (TN, USA) were evaluated for their sensitivity and specificity. Sensitivities of the lysates ranged from 29% to 83% whereas specificities ranged from 13% to 100%. Lysate ER-593 provided the most promising results with a sensitivity of 82% and specificity of 100%. This study provides suggests that a simple rapid slide agglutination assay for detecting blastomycosis may be used for screening patients with suspected B. dermatitidis infection.

  11. Pulmonary Blastomycosis in Vilas County, Wisconsin: Weather, Exposures and Symptoms

    Directory of Open Access Journals (Sweden)

    Dennis J. Baumgardner


    Full Text Available Purpose: Blastomycosis is a serious fungal infection contracted by inhalation of Blastomyces spores from the environment. Case occurrence in dogs in Vilas County, Wisconsin, has been associated with antecedent weather. We aimed to explore the effects of weather on the occurrence of human pulmonary blastomycosis in this area, and update exposure factors and symptoms since last published reports. Methods: Mandatory case reports were reviewed. Chi-square test was used for categorical data of exposures, comparing 1979–1996 (n=101 versus 1997–June 2013 (n=95. Linear regression was used to model local weather data (available 1990–2013; n=126; Southern Oscillation Index (SOI, North Atlantic Oscillation Index (NAOI, and Wisconsin River water discharge (WRD from the adjacent county (all available for 1984–2013; n=174; and case counts of known onset by warm (April–September and cold (October–March 6-month periods. Results: Distribution of pulmonary blastomycosis cases did not vary by season. Environmental exposures for the 1997–June 2013 group (mean age 45, 59% male were: residence(76%, excavation (42% and gardening (31%, all similar to the 1979–1996 group. Fishing (23% vs. 37%; P=0.09 and hunting (15% vs. 26%; P=0.13 exposures were less common in 1997–June 2013, but not significantly different. Overall, 69% of cases recalled some prior soil-disturbing activities. Considering the 6-month warm/cold periods, 19% of variation is explained by a direct relationship with total precipitation from two periods prior (P=0.005. There was no association of case occurrence with SOI, NAOI or WRD. Estimated annual incidence of blastomycosis for 1997–June 2013 was 27/100,000 compared with 44/100,000 for 1984–1996. Several symptoms were significantly less frequent in 2002–June 2013 compared to earlier years. Conclusions: As with dogs, human pulmonary blastomycosis occurrence is partially determined by antecedent precipitation. It is unclear if

  12. Probable Pulmonary Blastomycosis in a Wild Coyote (Canis latrans

    Directory of Open Access Journals (Sweden)

    Luis E. Rodríguez-Tovar


    Full Text Available A female coyote (Canis latrans was fatally injured by a vehicle on a road in San Luis Potosi, Mexico. Because of deteriorating clinical signs, the animal was euthanized. Postmortem examination of the lungs showed numerous small multifocal white nodules (0.5–1 cm diameter disseminated throughout. Histopathologic examination revealed multifocal coalescing granulomas with abundant macrophages, numerous neutrophils, fibroblasts, plasma cells, and lymphocytes. Abundant intracellular and extracellular thick-walled, refractile, spherical yeasts (10–15 μm were observed within the granulomas. The yeasts were intensely PAS-positive, with granular protoplasm. Broad-based single budding yeasts were occasionally present. Based on the microscopic findings of the pulmonary lesions and the morphological features of the organism, a diagnosis of chronic pyogranulomatous pneumonia caused by Blastomyces dermatitidis was made. To our knowledge, the case described herein is the first report of pulmonary blastomycosis in a wild coyote.

  13. Unusual osseous presentation of blastomycosis in an immigrant child: a challenge for European pediatricians

    Directory of Open Access Journals (Sweden)

    Codifava Margherita


    Full Text Available Abstract Background Blastomycosis, caused by the thermally dimorphic fungus Blastomyces dermatitidis is a systemic pyogranulomatous infection, endemic in United States and Canada, with few reported cases in Africa and Asia. It is uncommon among children and adolescents, ranging from 3% to 10%. Clinical features vary from asymptomatic spontaneously healing pneumonia, through acute or chronic pneumonia, to a malignant appearing lung mass. Blastomycosis can originate a "metastatic disease" in the skin, bones, genitourinary tract and central nervous system. Bone is the third most common site of blastomycotic lesions, after lung and skin. Bones may be involved in 14-60% of cases of blastomycosis. Direct visualization of single broadbased budding yeast with specific stains in sputum or tissue samples at microscopy is the primary method for diagnosis, while culture is timeconsuming and other methods are unreliable. Case presentation We report a case of severe osteoarticular Blastomycosis occurring in a 3-years-old presented to our Emergency Department with pain and swelling of the left knee, successfully treated with surgical curettage and antifungal therapy. To our knowledge this is the first case reported in Europe. Conclusions Blastomycosis represents a challenge for European physicians, and it should be included in the differential diagnosis of unexplained infections in patients coming from endemic areas.

  14. Endemic systemic mycoses: coccidioidomycosis, histoplasmosis, paracoccidioidomycosis and blastomycosis. (United States)

    Bonifaz, Alexandro; Vázquez-González, Denisse; Perusquía-Ortiz, Ana María


    Endemic deep or systemic mycoses are common in specific geographical areas of the world. Coccidioidomycosis is present in semi-desert areas, histoplasmosis and paracoccidioidomycosis in tropical regions and blastomycosis belongs to temperate climates. The two former are widely distributed in the American continent and some tropical regions of the world; the third is limited to Central and South America, and the last to North America and Central and East Africa. These mycoses all have a similar pathogenesis, as the inoculum enters the host through the respiratory tract. Cutaneous manifestations are secondary to lymphatic and hematogenous dissemination. These deep mycoses are exceptional in Europe. Most cases are observed in returning travelers from endemic areas, aid workers, archaeologists, speleologist and immigrants. However, there have been some autochthonous cases of histoplasmosis due to Histoplasma capsulatum var. capsulatum reported in European countries such as Italy and Germany. In this article, we provide up-to-date epidemiological, clinical, diagnostic and therapeutic data on the four most important imported systemic mycoses in Europe.

    Full Text Available We describe the clinical, laboratory, and imaging data of three patients who are proven cases of blastomycosis with cranial involvement. In this review, we discuss the imaging features of cranial blastomycosis with relevant clinical case examples including computed tomography (CT, magnetic resonance imaging (MRI, and advanced MR imaging techniques like magnetic resonance spectroscopy (MRS and MR perfusion. Literature is reviewed for modern-day diagnosis and treatment of this fatal intracranial infection, if not diagnosed promptly and managed effectively.

  17. Blastomycosis infection of the knee treated with staged total knee arthroplasty. (United States)

    MacLean, Ian S; Day, Shandra R; Moore, Christopher C; Browne, James A


    Blastomycosis is a rare fungal disease that can cause intraarticular infection and joint destruction requiring surgical reconstruction. We describe a patient who presented with destruction of the knee joint of unknown etiology. The patient was initially treated with debridement and spacer placement followed by antifungal therapy after cultures grew blastomycosis. Following adequate treatment of the infection, the patient was taken back to the operating room for reconstruction with a total knee arthroplasty. The patient had a successful outcome with no evidence of infection at two years following surgery. To our knowledge, this case report represents the first documented case in which a blastomycotic infection of a native knee was successfully treated with a two-stage total knee arthroplasty.

  18. Safety, tolerability, and immunogenicity of a recombinant, genetically engineered, live-attenuated vaccine against canine blastomycosis. (United States)

    Wüthrich, Marcel; Krajaejun, Theerapong; Shearn-Bochsler, Valerie; Bass, Chris; Filutowicz, Hanna I; Legendre, Alfred M; Klein, Bruce S


    Blastomycosis is a severe, commonly fatal infection caused by the dimorphic fungus Blastomyces dermatitidis in dogs that live in the United States, Canada, and parts of Africa. The cost of treating an infection can be expensive, and no vaccine against this infection is commercially available. A genetically engineered live-attenuated strain of B. dermatitidis lacking the major virulence factor BAD-1 successfully vaccinates against lethal experimental infection in mice. Here we studied the safety, toxicity, and immunogenicity of this strain as a vaccine in dogs, using 25 beagles at a teaching laboratory and 78 foxhounds in a field trial. In the beagles, escalating doses of live vaccine ranging from 2 × 10⁴ to 2 × 10⁷ yeast cells given subcutaneously were safe and did not disseminate to the lung or induce systemic illness, but a dose of vaccine dose of 10⁵ yeast cells was also well tolerated in vaccinated foxhounds who had never had blastomycosis; however, vaccinated dogs with prior infection had more local reactions at the vaccine site. The draining lymph node cells and peripheral blood lymphocytes from vaccinated dogs demonstrated gamma interferon (IFN-γ), tumor necrosis factor alpha (TNF-α), and granulocyte-macrophage colony-stimulating factor (GM-CSF) specifically in response to stimulation with Blastomyces antigens. Thus, the live-attenuated vaccine against blastomycosis studied here proved safe, well tolerated, and immunogenic in dogs and merits further studies of vaccine efficacy.

  19. Blastomycosis in Quebec (1981–90: Report of 23 Cases and Review of Published Cases from Quebec

    Directory of Open Access Journals (Sweden)

    G St-Germain


    Full Text Available Twenty-three cases of blastomycosis were reported in a survey conducted in the province of Quebec from 1981–90. Thirteen patients resided south of the St Lawrence River and the other 10, north. Two small geographical clusters were apparent in and around the cities of Sherbrooke and Quebec. The male to female ratio was 1.6:1 and the median age was 47 years (range 26 to 77. Lung involvement was observed in 19 cases and was the only site involved in 11. Cutaneous manifestations were reported in 11 cases while bone infection (three cases and central nervous system (CNS infections were also noted. Diagnosis was confirmed by culture in 21 cases and by histopathology in two cases. Of the 21 culture-positive cases, 12 strains of Blastomyces dermatitidis were isolated from lungs, nine from skin, and one each from bone and brain. Serodiagnostic tests by immunodiffusion or complement fixation were positive for only one of the 10 patients known to have been tested. Ten patients were treated with amphotericin B, 11 with ketoconazole, one with fluconazole and eight underwent surgery. While amphotericin B was used in eight of the 10 earliest treated cases, ketoconazole was administered in 10 of the 13 more recent cases. Of the patients for whom follow-up data have been obtained, 21 are reported cured (one of whom was not treated and one patient died of another cause. This survey confirms that blastomycosis is a rare disease in this endemic area and that patterns of therapy are changing.

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.

    Woods, Katharine S.; Barry, Maureen; Richardson, Danielle


    A 6-month-old male castrated Labrador retriever was presented for coughing and forelimb lameness. Blastomyces dermatitidis was identified in cytology of sputum and synovial fluid. Repeat arthrocentesis 7 months later revealed resolution of septic arthritis. Fungal septic arthritis should be considered for cases of monoarthritis and may respond to oral itraconazole treatment.

  3. Results of miconazole therapy in twenty-eight patients with paracoccidioidomycosis (South American blastomycosis). (United States)

    Negroni, R; Rubinstein, P; Herrmann, A; Gimenez, A


    Results are presented of treatment with miconazole, orally and intravenously, in patients with paracoccidioidomycosis. Twenty-eight male patients aged from 34 to 66 years and exhibiting various clinical forms of the disease were studied. Twenty-five came from endemic areas in north east Argentina (Chaco, Formosa, Misiones, Corrientes and northern Santa Fe) and the remaining three from Paraguay. Twenty patients were engaged in agricultural work or at woodmills. single or multiple lesions were observed in 24 cases. Thirteen were suffering from infection of the larynx and in two of them a tracheotomy was necessary. Twenty-three showed pulmonary lesions on X-rays. Twelve had ganglionic lesions, eight had cutaneous lesions and one patient had osteoarthritis of the knee. One patient had hepatomegaly which was unrelated to chronic alcoholism. Fourteen patients had received previous treatments such as sulphonamides and amphotericin B (7 cases); sulphonamides (3), sulphonamides and the combination sulfamethoxazole + trimethoprim (3), and one patient had received all three medications. All patients had relapsed before starting miconazole therapy. Diagnosis was established by the presence of P. brasiliensis in all cases, recovered either from cutaneous or mucosal biopsy samples or from the sputum. Complement fixation tests were positive in all patients at the onset of the treatment and the immunodiffusion reactions showed precipitation bands in 27/28 patients. Skin tests with P. brasiliensis antigens proved to be positive in 18 cases and negative in 10. The erythrocyte sedimentation rate was markedly accelerated in 22 patients (greater than 20 mm in the first hour).(ABSTRACT TRUNCATED AT 250 WORDS) Images p24-a Fig 1 Fig 2 PMID:122643

  11. Blastomyces dermatitidis prostatic and testicular infection in eight dogs (1992-2005). (United States)

    Totten, Amy Kaye; Ridgway, Marcella D; Sauberli, Debra S


    This was a retrospective case study of eight dogs diagnosed with prostatic or testicular B. dermatitidis infection. Signalment, clinical presentation, diagnostic procedures, and treatment options were evaluated. Review of medical records of dogs diagnosed with blastomycosis at the University of Illinois Veterinary Teaching Hospital from 1992 to 2005 yielded four dogs with prostatic blastomycosis (PB) and four dogs with testicular blastomycosis (TB). Three of the four dogs with PB and all four dogs with TB had evidence of urogenital disease. Three dogs with PB had an elevated body temperature and all had systemic disease. All dogs with TB had a normal body temperature, and three had systemic disease and one had clinical signs limited to testicular disease. Cytology or histopathology was used to diagnose PB or TB. Treatment included itraconazole or fluconazole with or without nonsteroidal anti-inflammatory drugs. PB and TB are infrequently recognized and may be under diagnosed due to failure to specifically evaluate these tissues. PB or TB should be considered in the evaluation and staging of male dogs with blastomycosis. Male dogs with urogenital signs should be evaluated via prostatic or testicular cytology or histopathology since proper identification and management of PB or TB may improve overall treatment success.

    Histoplasmosis is the most common endemic mycosis in North America, and is followed by coccidioidomycosis and blastomycosis. Although the majority of these infections in immunocompetent persons are self-limited, some patients can develop severe pneumonitis or various forms of chronic pulmonary infection. Cryptococcoci, Aspergillus, Candidas, and Mucorals are ubiquitous organisms, which may affect immunocompromised patients. Specific imaging findings can be expected, depending on the organisms involved, underlying patients' conditions (immune status), and specific situations after immune depleting procedures.

    No well-defined Blastomyces-specific antigens are currently available. We used sodium dodecyl sulfate-polyacrylamide gel electrophoresis and immunoblotting to identify immunologically active molecules in the cell wall of B. dermatitidis. A major immunoreactive 120-kD protein (WI-1) was present in all five strains studied and comprised 5% of the protein in the cell wall extract obtained after freezing and thawing yeast cells. WI-1 was recognized by serum from all 10 patients with blastomycosis but by none of those from 5 patients with histoplasmosis. It was purified by electroelution, radiolabeled with 125I, and incorporated into a radioimmunoassay (RIA) for serodiagnosis of blastomycosis. Antibody to WI-1 was detected in 58 (85%) of 68 patients with blastomycosis (geometric mean titer, 1:2,981), in two (3%) of 73 patients with histoplasmosis, coccidioidomycosis, sporotrichosis, or candidiasis (titers, 1:86 and 1:91) and in none of 44 healthy persons. WI-1 was shown to be a surface molecule abundant on B. dermatitidis yeasts that were indirectly stained with serum from a rabbit immunized with WI-1. Approximately 0.93 pg of WI-1 or 4.7 x 10(6) WI-1 molecules were found on the surface of an individual yeast using an antigen-inhibition RIA; none was found on Histoplasma capsulatum or Candida albicans yeasts. We conclude that WI-1 is a novel, immunologically active surface molecule on the invasive form of B. dermatitidis and that WI-1 can be used to reliably detect antibody and study the immunopathogenesis of blastomycosis.

  15. Aspergillosis and other systemic mycoses. The growing problem. (United States)

    Fraser, D W; Ward, J I; Ajello, L; Plikaytis, B D


    To measure the incidence in the United States of systemic mycoses necessitating hospitalization, we reviewed discharge records of 1,875 hospitals participating in the Professional Activity Study of the Commission on Professional and Hospital Activities. Projected incidence rates in 1976 ranged from 23.0 per million for histoplasmosis to 0.2 per million for blastomycosis. High prevalences of leukemia or lymphoma (5.9% to 10.2%) or of other malignancies (9.9% to 13.2%) were recorded in patients with aspergillosis, candidasis, or cryptococcosis. High prevalences of chronic obstructive lung disease (9.6% to 9.9%) were recorded in those with aspergillosis or histoplasmosis. Marked increases from 1970 to 1976 were found in the incidence of aspergillosis (158%), actinomycosis (92%), cryptococcosis (78%), and coccidioidomycosis (74%). Increasing numbers of persons with immunosuppressive conditions, migration of susceptible persons into hyperendemic areas, and aging of the population contributed to the increases.

  16. Generalized calcinosis cutis associated with disseminated paecilomycosis in a dog. (United States)

    Holahan, Melissa L; Loft, K Earl; Swenson, Cheryl L; Martinez-Ruzafa, Ivan


    A 4-year-old spayed female mixed breed dog was referred to the Michigan State University, Veterinary Teaching Hospital (MSU-VTH) with vomiting, lethargy and anorexia of 2 weeks duration. Abdominal radiographs and ultrasonography showed hepatosplenomegaly. Cytological evaluation of ultrasound-guided fine needle aspirates of the liver and spleen revealed fungal organisms and pyogranulomatous inflammation; fungal culture documented Paecilomyces variotii infection. The dog received antifungal therapy and supportive care. Multiple firm plaque-like skin lesions, predominantly involving the inguinal region, developed 18 days after initial presentation and were diagnosed histopathologically as calcinosis cutis. While generalized calcinosis cutis has been reported in three dogs with blastomycosis and one dog with leptospirosis, the association with disseminated Paecilomyces spp. infection is novel.

    Full Text Available Paracoccidioidomycosis, formerly known as South American Blastomycosis, can be installed by inhalation or by skin lesions or mucous membranes. Poor hygiene and oral diseases are theports of entry most common for this fungus, once in the bloodstream becomes systemic to infect the lungs, spleen, liver, kidneys, pancreas, bones and lymph nodes. The fungus grows on plants and soils in geographical and climatic conditions common areas of the valley of the Paraíba do Sul. The disease has preferences for males, for white and aged between 41 and 50. The primary lesion compromises the oral tongue, gums, lips and other mucous, isolated or associated. The oral lesions appear as lesions located andbulky appearance of micro granules, resembling a blackberry. This study examined medical records of the Municipal Health Department of Volta Redonda, whose primary lesion was in the mouth. We selected 11patient records that corroborated with the literary data, emphasizing the language as the most affected andthe association with bad oral hygiene and oral habits such as smoking and alcohol consumption. All evaluated had pulmonary infection and were treated clinically by the administration of sulfa drugs, outpatient and six to twelve months. It was concluded this could be an endemic area and the importance of the role of the Dental Surgeon in the diagnosis of the disease.

    Full Text Available Nocardia spp are gram-positive, aerobic, acid-fast bacteria which exist as saprophytes in nature. Invasive disseminated infections are particularly common in immunocompromised or debilitated hosts. Superficial infections with Nocardia spp occur as a result of local trauma and contamination of the wound. Clinically, it presents as acute infection (abscesses or cellulitis, mycetoma, or sporotrichoid infection. Differential diagnosis includes eumycetoma, chromomycosis, blastomycosis, coccidioidomycosis, sporotrichosis, tuberculosis, botryomycosis, syphilis, yaws, and neoplasia. Its diagnosis is confirmed by demonstrating the causative organism in exudates (as granules, tissue specimens, or cultures. Early diagnosis will obviate need for drastic surgical measures as early institution of chemotherapy is effective in most patients. However, its diagnosis is often delayed due to diverse clinical presentations and for want of clinical suspicion, particularly in non-endemic areas. This paper presents 4 clinical forms of this not so uncommon disease, emphasizing the importance of high index of clinical suspicion, especially in non-endemic regions; and the significance of repeated examination of exudates for Nocardia granules for an early diagnosis.

    Full Text Available Several case reports of involvement of the nervous system by Paracoccidioides brasiliensis have been published, changing thus the concept that the nervous system would no be adequate to the proliferation of this fungus. In the material of the Department of Pathology of the University of São Paulo Medical School, collected up to September 1964, 145 cases of paracoccidioidomycosis were found. In 14 of them there were lesions of the nervous system, giving an incidence of 9,65%. This high incidence contradicts the frequent assumption that the involvement of the nervous system in cases of South American blastomycosis is exceptional. In our material most of the cases of neuroblastomycosis had not systemic lesions, 2 of them having isolated involvement of the nervous system. This fact does not agree with the frequent observation of patients with lesions in all organs but the nervous system. There are no pathophysiologic reasons to explain such contradiction, but it can be assumed that individual conditions, in some cases, make the nervous system vulnerable to the parasite. Of the 14 cases studied, 5 had lesions of the meninges and 9 had gra-nulomata of the brain. Of the 5 cases with meningitis, 3 had an isolated basilar leptomeningitis; in 1 case lesions of the pia-arachnoid of the brain convexity were also found, and in another one the spinal meninges were also involved as well the spinal roots. The granulomata of the brain were isolated in 5 cases and multiple in 4. The most frequent site of the lesions was the cerebral hemispheres (6 cases; in 2 cases the cerebellum was involved; the thalamus, pons and medulla were involved in one case each. This predominance of the hemispheric localization must be related to the larger blood supply of this parte of the nervous system, owing to the hematogenic route followed by the parasite. In our material no lesions of the spinal cord were found. However, no definitive conclusions can be drawn, as there was no

  1. Endemic fungal infections in inflammatory bowel disease associated with anti-TNF antibody therapy. (United States)

    Ordonez, Miguel E; Farraye, Francis A; Di Palma, Jack A


    Patients with inflammatory bowel disease are susceptible to complications from pharmacologic treatment of their disease. Tumor necrosis factor (TNF)-α inhibitors are being used increasingly in the treatment of inflammatory bowel disease and can be associated with adverse events, including common infections, and rarely the development of serious life-threatening opportunistic infections. TNF-α inhibitors have the ability to prevent an effective patient granulomatous response, and this may be associated with an increased risk of developing mycobacterial and certain fungal infections, including histoplasmosis, blastomycosis, and coccidioidomycosis, endemic in several parts of the United States. The concern for invasive fungal infection was realized during clinical trials and further demonstrated after the marketing of TNF-α inhibitors. Because of this awareness, the Food and Drug Administration developed an adverse event-reporting system to capture cases of infections associated with the use of TNF-α inhibitors. These opportunistic fungi have a great degree of regional variability, and it has been very difficult to quantify the incidence of infection in patients treated with TNF-α inhibitors. Currently, there are no formal guidelines regarding the use of TNF-α inhibitors and these fungal infections. Considering that gastroenterologists have embraced the use TNF-α inhibitors as a valuable armamentarium in the treatment of inflammatory bowel disease, they must be aware of therapy-related infectious complications, including appropriate diagnostic, therapeutic, and preventive strategies. In this article, we explore the association of these fungal entities in relation to the TNF-α inhibitor therapy by considering information provided in the gastroenterology, infectious diseases, rheumatology, and transplant literature. Finally, we provide some recommendations on diagnosis and treatment.

  2. AmBisome: liposomal formulation, structure, mechanism of action and pre-clinical experience. (United States)

    Adler-Moore, Jill; Proffitt, Richard T


    Amphotericin B is the treatment of choice for life-threatening systemic fungal infections such as candidosis and aspergillosis. To improve this drug's efficacy and reduce its acute and chronic toxicities, several lipid formulations of the drug have been developed, including AmBisome, a liposomal formulation of amphotericin B. The liposome is composed of high transition temperature phospholipids and cholesterol, designed to incorporate amphotericin B securely into the liposomal bilayer. AmBisome can bind to fungal cell walls, where the liposome is disrupted. The amphotericin B, after being released from the liposomes, is thought to transfer through the cell wall and bind to ergosterol in the fungal cell membrane. This mechanism of action of AmBisome results in its potent in vitro fungicidal activity while the integrity of the liposome is maintained in the presence of mammalian cells, for which it has minimal toxicity. In animal models, AmBisome is effective in treating both intracellular (leishmaniasis and histoplasmosis) and extracellular (candidosis and aspergillosis) systemic infections. Because of its low toxicity at the organ level, intravenous AmBisome can be safely delivered at markedly high doses of amphotericin B (1-30 mg/kg) for the treatment of systemic fungal infections. AmBisome has a circulating half-life of 5-24 h in animals, and in animal models appears to localize at sites of infection in the brain (cryptococcosis, aspergillosis, coccidioidomycosis), lungs (blastomycosis, paracoccidioidomycosis, aspergillosis) and kidneys (candidosis), delivering amphotericin B that remains bioavailable in tissues for several weeks following treatment.

  3. Posaconazole: Use in the Prophylaxis and Treatment of Fungal Infections. (United States)

    Clark, Nina M; Grim, Shellee A; Lynch, Joseph P


    Posaconazole, a fluorinated triazole antifungal drug, is approved by the U.S. Food and Drug Administration (FDA) for (1) prophylaxis against Aspergillus and Candida infections in immunocompromised patients at high risk for these infections and (2) oropharyngeal candidiasis (OPC), including cases refractory to fluconazole and/or itraconazole. The European Medicines Agency (EMA) has approved posaconazole for (1) treatment of aspergillosis, fusariosis, chromoblastomycosis, and coccidioidomycosis in patients who are refractory to or intolerant of other azoles or amphotericin B; (2) first-line therapy for OPC for severe disease or in those unlikely to respond to topical therapy; and (3) prophylaxis of invasive fungal infections in high-risk hematologic patients and stem cell transplant recipients. In addition to approved indications, posaconazole has been used with success as salvage therapy for invasive mold infections and endemic mycoses in patients who are refractory to or intolerant of other antifungal agents, and as prophylaxis or salvage therapy in children, for whom indications are more limited owing to a paucity of data. Posaconazole has potent in vitro activity against a broad range of fungi and molds, including Aspergillus, Candida, Cryptococcus, filamentous fungi, and endemic mycoses including coccidioidomycosis, histoplasmosis, and blastomycosis. Importantly, posaconazole is much more active than other azoles against many Mucorales species and the combination of posaconazole with other antifungal agents may be synergistic. Hence, posaconazole is a potential candidate as a single or combination agent for difficult-to-treat fungal infections. Posaconazole has an excellent safety profile; to date, serious side effects are rare, even with prolonged use. However, newer posaconazole formulations achieve higher blood levels and it remains to be seen whether this may lead to an increase in the rate of adverse effects. Currently, posaconazole is used predominantly

    Full Text Available Lacaziose ou doença de Jorge Lobo é micose crônica, granulomatosa, causada por implantação traumática do fungo Lacazia loboi - patógeno não cultivável até o presente - nos tecidos cutâneo e subcutâneo, manifestando-se clinicamente por lesões nodulares queloidianas predominantes, envolvendo sobretudo pavilhões auriculares, face, membros superiores e inferiores, e não comprometendo as mucosas. A maioria dos casos humanos está registrada em países da América do Sul. Entretanto, a enfermidade apresenta aspectos epidemiológicos destacados, como o aparecimento em tribo Caiabi, no Brasil Central e em mamíferos não humanos, golfinhos de duas espécies (Tursiops truncatus e Sotalia guianensis capturados na costa da Flórida (EUA, na foz do rio Suriname, na costa de Santa Catarina (Brasil, no golfo de Gasconha (baía de Biscaia-Europa, com manifestações cutâneas e achados histopatológicos muito similares às encontradas no homem.

    Full Text Available Two cases of intramedullary paracoccidioidomycosis are reported. Paracoccidioidomycosis is a systemic disease that involves the buccopharyngeal mucosa, lungs, lymph nodes and viscera and infrequently the central nervous system. Localization in the spinal cord is rare. Case 1: a 55-year old male admitted with crural pararesis, tactile/painful hypesthesia and sphincter disturbances of 15 days duration. Cutaneous-pulmonary blastomycosis was diagnosed 17 years ago. Myelotomography showed a blockade of T3-T4 (intramedullary lesion. The lesion surgically removed was a Paracoccidioides brasiliensis granuloma. Treatment with sulfadiazine was started after the surgery. Follow-up of 15 month showed an improvement of the clinical signs. Case 2: a 57-year old male was admitted elsewhere 6 months ago and, with a radiologic diagnosis of pulmonary paracoccidioidomycosis, was treated with amphotericin B. He progressively developed paresthesia and tactile/ pain anaesthesia on the left side, sphincter disturbances and tetraparesis with bilateral extensor plantar response and clonus of the feet. Myelotomography showed a blockade of C4-C6 (intramedullary lesion. The lesion was not found during surgical exploration and the patient deteriorated and died. Post-mortem examination revealed an intramedullary tumor above the site of the mielotomy (Paracoccidioides brasiliensis granuloma. The preoperative diagnosis of intramedullary paracoccidioidomycotic granulomas is difficult because the clinical and radiologic manifestations are uncharacteristic. Clinical suspicion was possible in our cases based on the history of previous systemic disease. Contrary to intracranial localizations, paracoccidioidomycotic granulomas causing progressive spinal cord compression may require early surgery because response to clinical treatment is slow and the reversibility of neurological deficits depends on the promptness of the decompression.São relatados dois casos de granuloma blastomic

    can remain latent for many years before presenting as the host's immunocompetence wanes. It can present with a variety of skin findings or as a nonspecific febrile illness, and preferred treatment consists of ceftazidime or a carbapenem with trimethoprim/sulfamethoxazole (TMP/SMX) for 2 weeks, then continuing TMP/SMX for at least 3 months. Leptospirosis is a waterborne zoonosis that is often prevalent after heavy rains or flooding. Different forms exist, including Fort Bragg fever, which produces a distinctive erythematous papular rash on the shins. Doxycycline is often sufficient; however, volume and potassium repletion may be necessary if renal involvement exists. Chromobacterium violaceum infection may occur after open skin is exposed to stagnant or muddy water. Cultured colonies produce a unique violacein pigment, and treatment typically consists of a carbapenem. Both typical and atypical fungal infections are increased in the flooding disaster scenario, such as dermatophytosis, chromoblastomycosis, blastomycosis, and mucormycosis. Appropriate antifungals should be used. In addition, land inundated with water expands the habitat for parasites and/or vectors, thus increased vigilance for regional parasitic infections is necessary after a flood. Lastly, noninfectious consequences of a flooding disaster are also common and include miliaria, immersion foot syndromes, irritant and allergic contact dermatitis, traumatic wounds and animal bites, and arthropod assault, as well as exacerbation of existing skin conditions such as atopic dermatitis, psoriasis, and alopecia areata due to increased stress or nonavailability of daily medications.

    completamente y el paciente continúa bajo control en el servicio.Paracoccidioidomycosis (PCM or South-american Blastomycosis is the most important systemic mycosis in Latin America, is relatively common in Brazil, Venezuela, Colombia, Ecuador and Argentina. Sporadic cases can also be seen in some other countries, which is a rare progressive and fatal if not treated. It has been regarded as a multifocal disease with oral lesions as the prominent feature. It is caused by a dimorphic fungus, Paracoccidioides brasiliensis, which mainly affects the skin, lymph nodes, lungs and mucous membranes, oral, nasal and gastrointestinal. Depending on the specific immunity of the host, the infection can take many forms and affects one or more organs, becoming a serious and potentially fatal disease. It is very important for health professionals worldwide have knowledge about Paracoccidioidomycosis because sometimes the disease only manifests itself many years after you have left the endemic area. To provide useful information about the diagnosis and treatment of disease A case report of case of male patient 48 years old from a rural area of Brazil Oath, presenting multiple painful ulcers on the gums and palate of 3 months duration, referred to chronic smoking history, clinical examination extraoral lesions are discarded in other intraoral examination bodies and multiple ulcers were observed necrotic and granulomatous background located on the gums and palate. We performed an incisional biopsy of the lesion and the material was sent for pathologic examination. The pathology report confirmed the clinical impression of Paracoccidioidomycosis. The patient was treated with the use of sulfamethoxazole + trimethoprim - 800/60 mg/day, orally every 12 hours for 30 days. The oral lesions disappeared completely and the patient remains under control in the service.
