1/30. lobomycosis. Report of the eighth Colombian case and review of the literature.The eighth Colombian case of lobomycosis and the one hundredth in the world literature is reported here. The patient was a 38-year-old female who showed a bilobed mass on the left forearm which had appeared at the site from where a similar lesion had been excised 19 years previously. She had always lived in a rural area, located in the humid subtropical forest. The tissue reactions to the fungus as well as the fruitless attempts to culture it are described. An analysis of the relevant literature is made and suggestions for experimental animal models are given in the text.- - - - - - - - - - ranking = 1keywords = fungus (Clic here for more details about this article) |
2/30. Imaging of mucormycosis skull base osteomyelitis.skull base osteomyelitis (SBO) is typically bacterial in origin and caused by pseudomonas, although the fungus Aspergillus has also rarely been implicated. SBO generally arises from ear infections and infrequently complicates sinonasal infection. Rhinocerebral Mucor infection is characteristically an acute, fulminant, and deadly infection also affecting the orbits and deep face and is associated with intracranial complications. Bony involvement is uncommon because of the angioinvasive nature of the fungus. More recently, chronic invasive Mucor sinusitis has been described. We report the unusual clinical and imaging features of a patient with biopsy-proven invasive mucormycosis arising from chronic isolated sphenoid sinus disease, who presented with extensive SBO and a paucity of deep facial, orbital, or intracranial involvement.- - - - - - - - - - ranking = 2keywords = fungus (Clic here for more details about this article) |
3/30. Multiple lung abscesses due to Ochroconis gallopavum, a dematiaceous fungus, in a nonimmunocompromised wood pulp worker.An occurrence of multiple chronic lung abscesses managed by lobectomy is described. These abscesses were present for 13 years in the patient, a nonimmunocompromised wood pulp worker. The patient had hemoptysis at presentation. The organism isolated was Ochroconis gallopavum, a dematiaceous fungus known to cause disease in immunocompromised patients and epidemic encephalitis in poultry. The fungus is typically found in warm environments and in decaying compost; for this reason, we postulate that his illness was occupationally acquired.- - - - - - - - - - ranking = 6keywords = fungus (Clic here for more details about this article) |
4/30. Chronic sino-naso-orbital fungal infection due to pseudallescheria boydii in a nonimmunocompromised host--a case report.A case of recurrent sino-naso-orbital fungal infection due to pseudallescheria boydii described in a 28 yrs. old man, who appeared immunocompetent, and was found negative for hiv I and II by ELISA tested on two occasions. The fungal culture was negative. It is very essential to identify P boydii as miconazole is the only antifungal drug of choice for this fungus. The pathologist plays an important role in identifying this fungus when fungal culture fails to yield the growth. The pathologist has to look for clinching clues such as "intercalary conidia" and "chlamydoconidia" to distinguish P boydii from Aspergillus.- - - - - - - - - - ranking = 2keywords = fungus (Clic here for more details about this article) |
5/30. Isolated chronic cough with sputum eosinophilia caused by Humicola fuscoatra antigen: the importance of environmental survey for fungus as an etiologic agent.We report here a 35-year-old man with isolated chronic cough associated with sputum eosinophilia in which Humicola fuscoatra (H. fuscoatra) antigen was an etiologic agent. He was admitted for the diagnosis and the treatment of his severe nonproductive cough. Although 80% of the nucleated cells in his induced sputum were eosinophils, he did not have bronchial hyperresponsiveness to methacholine or heightened bronchomotor tone. Bronchodilator therapy was not effective against his coughing. His cough worsened on his return home, suggesting the existence of some etiologic agent in his house. H. fuscoatra was isolated from his house, and the bronchoprovocation test with H. fuscoatra antigen was positive: i.e., development of coughing and decrease in capsaicin cough threshold (capsaicin concentration causing five or more coughs) from the prechallenge value of 31.3 microM to 1.95 microM at 6 and 48 hr, respectively, after the challenge. In addition, repeated environmental survey for fungi was suggestive of the importance of H. fuscoatra in the sputum eosinophilia. This is the first report concerning chronic cough with sputum eosinophilia caused by allergic reaction to H. fuscoatra antigen.- - - - - - - - - - ranking = 4keywords = fungus (Clic here for more details about this article) |
6/30. Rectal botryomycosis mimicking carcinoma.Botryomycosis is a granulomatous disease that was first recognized in horses. The lesion is infective with fungus-like grains similar to the sulfur granules in actinomycosis. We report 54-year-old woman with a strong suspicion of rectal carcinoma that turned out to be rectal botryomycosis. She responded to erythromycin.- - - - - - - - - - ranking = 1keywords = fungus (Clic here for more details about this article) |
7/30. Bipolaris spicifera causes fungus balls of the sinuses and triggers polypoid chronic rhinosinusitis in an immunocompetent patient.We report the rare case of a 19-year-old immunocompetent male suffering both from fungus balls of the sinuses and from chronic rhinosinusitis with massive polyposis. Endoscopic sinus surgery revealed grayish brown necrotic masses embedded in viscous eosinophilic mucus. Inoculated onto petri dishes, these masses as well as the mucus grew a dark pigmented fungus, which was identified as Bipolaris spicifera.- - - - - - - - - - ranking = 6keywords = fungus (Clic here for more details about this article) |
8/30. classification of fungal sinusitis in immunocompetent patients.OBJECTIVE: The objective of this study was to review the subgroup classification of fungal sinusitis in immunocompetent patients. methods: The study design included 19 immunocompetent patients with fungal sinusitis who were operated on between 1993 and 1998. RESULTS: Ten of 19 patients showed a fungus ball. They underwent a limited surgical endoscopic procedure, and no further treatment was needed. Four patients had allergic fungal sinusitis and were treated postoperatively with irrigation, topical steroids, and oral steroids in 2 patients as well. Five patients had chronic sinusitis with significant bone erosion. All 5 underwent an extensive endoscopic procedure and were treated postoperatively by repeated irrigation, endoscopic cleaning, and no antifungal preparation. Two patients of this group are reported broadly. CONCLUSIONS: Fungal sinusitis in immunocompetent patients is not a rare condition and can be divided into 3 categories: 1) fungus ball, 2) chronic erosive (noninvasive) fungal sinusitis, and 3) allergic fungal sinusitis. The symptomatology, treatment, and prognosis varied significantly among the 3 different categories.- - - - - - - - - - ranking = 2keywords = fungus (Clic here for more details about this article) |
9/30. blastomycosis: a reminder of kentucky's other fungus.Although not as common as histoplasmosis, the disease caused by blastomyces dermatitidis is also endemic in the Commonwealth of kentucky. Greater clinical awareness of this systemic mycosis and the newer effective forms of treatment may lessen the significant morbidity and mortality of this potentially serious infection. To illustrate the varied manifestations of this illness, we contrast the presentation of an urban female with blastomycosis and atypical chest radiographic changes to the more classic features of blastomycosis described in the literature.- - - - - - - - - - ranking = 4keywords = fungus (Clic here for more details about this article) |
10/30. Chronic bilateral otomycosis caused by aspergillus niger.aspergillus niger, an opportunistic filamentous fungus, was identified as the cause of chronic bilateral otomycosis in a 46-year-old female patient who was unresponsive to different drugs. The patient showed signs of erythema, otalgia, itching, otorrhoea and presence of greyish black coloured mass in both the ear canals. The direct microscopical examination of the ear debris in potassium hydroxide preparations, Giemsa, phase contrast and Gram revealed many thin, branched septate hyphae, condia and conidiophores morphologically indistinguishable from Aspergillus spp. The histopathological section of the ear wax mass by haematoxylin and eosin and periodic acid-Schiff techniques also showed similar fungal elements. The patient responded to 1% solution of mercurochrome. The use of mercurochrome in developing countries like india may be recommended to treat the fungal otitis in patients. We also emphasize that 'Narayan' stain should be routinely employed by microbiology and public health laboratories to study the morphology of pathogenic fungi.- - - - - - - - - - ranking = 1keywords = fungus (Clic here for more details about this article) |
