1/172. phaeohyphomycosis in kidney transplant patients.Dematiaceous fungi are being increasingly recognized as pathogens in organ transplant recipients. This investigation reports five cases of subcutaneous phaeohyphomycosis that occurred in five kidney transplant recipients in the Renal Unit at the San Vicente de Paul Hospital, Medellin, colombia. fungi of the genus exophiala were isolated in three cases, but the agent was not identified in two cases. physicians are likely to develop increased awareness of the clinical manifestation of infection with the dematiaceous fungi as the population of immunocompromised hosts continues to grow.- - - - - - - - - - ranking = 1keywords = mycosis (Clic here for more details about this article) |
2/172. mucormycosis, a threatening opportunistic mycotic infection.mucormycosis is a rare and invasive mycotic opportunistic infection, occurring mostly in predisposed patients, mainly diabetics and immunocompromised individuals. The evolution of this fungal infection is frequently fatal unless aggressive treatment is started, or predisposing factors are handled. Our first patient was a known diabetic who had ketoacidotic coma at admission, complicated with pulmonary mucormycosis, and needed surgical resection followed by antimycotic therapy. The second patient did not survive his severe aplastic anemia (with neutropenia) and hemochromatosis (treated with desferrioxamine), complicated with a systemic rhizopus infection, despite treatment with amphotericin b and granulocyte-colony-stimulating factors.- - - - - - - - - - ranking = 329.91914821985keywords = mycotic infection, mycosis (Clic here for more details about this article) |
3/172. mucormycosis of the central airways: CT findings in three patients.Computed tomographic (CT) findings are described in three diabetic patients with central airways mucormycosis. The CT findings of the tracheobronchial mucormycosis include enhancing areas of mural thickening (n = 3), luminal narrowing (n = 3), intramural air (n = 3), low-attenuation nonenhancing bronchial wall thickening (n = 2), and bronchonodal fistula formation (n = 1). These CT features in a diabetic patient should raise a high index of suspicion for tracheobronchial mucormycosis, particularly when typical radiographic features of pulmonary tuberculosis are absent.- - - - - - - - - - ranking = 1.4keywords = mycosis (Clic here for more details about this article) |
4/172. Combined anti-fungal therapy and surgical resection as treatment of pulmonary zygomycosis in allogeneic bone marrow transplantation.Opportunistic fungal infection is a rare but severe complication in allogeneic bone marrow transplant (BMT) recipients. We report a 49-year-old patient who developed pneumonitis after BMT, due to a mucorales fungus (class Zygomycetes), absidia corymbifera. Infections due to mucormycosis are likely to become increasingly recognized even though the occurrence after BMT has only been described sporadically. We postulate that the patient was contaminated before BMT despite no intensive drug treatment or other iatrogenic features, related to his poor living conditions and developed the infection during aplasia. He immediately received i.v. liposomal amphotericin b (AmBisome) and GM-CSF. Because there was no response, the infected area and necrotic tissue were resected. Despite initial clinical and biological improvement and the absence of Mucor on mycological examination post-surgery, the patient died 3 weeks later from bilateral pulmonary infection and multiorgan failure.- - - - - - - - - - ranking = 1keywords = mycosis (Clic here for more details about this article) |
5/172. Long-term survival of a patient with invasive cranial base rhinocerebral mucormycosis treated with combined endovascular, surgical, and medical therapies: case report.OBJECTIVE: Rhinocerebral mucormycosis is a clinical syndrome resulting from an opportunistic infection caused by a fungus of the order mucorales. The prognosis of rhinocerebral mucormycosis, once considered uniformly fatal, remains poor. Even with early diagnosis and aggressive surgical and medical therapy, the mortality rate is high. We present a patient with rhinocerebral mucormycosis involving the paranasal sinuses and cranial base who experienced long-term survival after multimodality treatment. Clinical characteristics of the disease are discussed, and the literature is reviewed. CLINICAL PRESENTATION: A 24-year-old diabetic man presented with invasive rhinocerebral mucormycosis involving the paranasal sinuses, right middle fossa, and right cavernous sinus. INTERVENTION: The patient underwent endovascular sacrifice of the involved carotid artery and radical resection of the cranial base, including exenteration of the cavernous sinus. Reconstruction with a local muscle flap was performed. He continued to receive intravenous and intrathecal administration of antibiotics. CONCLUSION: Long-term survival with invasive rhinocerebral mucormycosis is rare, but possible, with aggressive multimodality treatment, including carotid sacrifice for en bloc resection of the pathology, when indicated.- - - - - - - - - - ranking = 1.8keywords = mycosis (Clic here for more details about this article) |
6/172. Pulmonary rhizopus infection in a diabetic renal transplant recipient.Infectious complications after renal transplantation remain a major cause of morbidity and mortality. mucormycosis is a rare infection in renal transplant recipients; however, mortality is exceedingly high. risk factors predisposing to this disease include prolonged neutropenia, diabetes, and patients who are immunosuppressed (Singh N, Gayowski T, Singh J, Yu LV. Invasive gastrointestinal zygomycosis in a liver transplant recipient: case report and review of zygomycosis in solid-organ transplant recipients, Clin Infect Dis 1995: 20: 617). life-threatening infections can occur, as this fungus has the propensity to invade blood vessel endothelium, resulting in hematological dissemination. We report a case of cavitary rhizopus lung infection, 2 months after renal transplantation, where the patient was treated successfully with amphotericin b and surgical resection of the lesions with preservation of his allograft function. In this era of intensified immunosuppression, we may see an increased incidence of mucormycosis in transplant population. Invasive diagnostic work-up is mandatory in case of suspicion; amphotericin b and, in selected cases, surgical resection are the mainstays of therapy.- - - - - - - - - - ranking = 0.8keywords = mycosis (Clic here for more details about this article) |
7/172. Management and outcome of brain abscess in renal transplant recipients.Although infection is the commonest central nervous system complication following renal transplantation, brain abscess is uncommon. Over the last 11 years, five renal transplant recipients who had brain abscesses were treated by computed tomography (CT)-guided stereotactic aspiration. Three patients had a fungal abscess, one a tuberculous abscess and the other had a methicillin-resistant staphylococcus aureus abscess. One patient required a craniotomy for the excision of a fungal abscess which was persistent after two CT-guided stereotactic aspirations. The survivors in this group are the patient with a tuberculous abscess who is alive and well 5 years after diagnosis, and another with a dematiaceous fungal abscess (phaeohyphomycosis). CT-guided stereotactic surgery is minimally invasive, and can safely be performed in these patients. It often leads to an aetiological diagnosis in renal transplant recipients with brain abscesses. Specific antibiotic management directed towards the causative organism rather than empirical treatment can be instituted following the procedure. Although the ultimate prognosis in these patients is bleak even with specific antibiotic therapy, an occasional patient might have a good outcome with prompt and appropriate therapy.- - - - - - - - - - ranking = 0.2keywords = mycosis (Clic here for more details about this article) |

9/172. stenotrophomonas maltophilia endophthalmitis after intraocular lens implantation.BACKGROUND: stenotrophomonas maltophilia is an opportunistic, gram-negative bacillus. endophthalmitis induced by S. maltophilia has been described in only two cases after intraocular lens implantation. We report S. maltophilia endophthalmitis in two patients with diabetes mellitus after intraocular lens implantation and compare the characteristics of the S. maltophilia-induced endophthalmitis with two previous cases. methods: A 68-year-old woman and a 74-year-old man with diabetes mellitus developed S. maltophilia endophthalmitis within 5 days of intraocular lens implantation. We performed intraocular lens removal and vitrectomy, which resolved the inflammation. No recurrences were found. RESULTS: Cultures grew S. maltophilia in both cases, and one of the organisms was multi-resistant. The final visual acuity was counting fingers and 0.3. The first case revealed a tractional retinal detachment during vitrectomy. CONCLUSIONS: S. maltophilia is a potential opportunistic intraocular pathogen, and the incidence of multiresistant S. maltophilia is increasing. S. maltophilia causes acute endophthalmitis, and its prognosis may not be poor unless the eye has a history of serious disease before the cataract surgery. The combined procedure of intraocular lens removal and vitrectomy was useful in resolving the inflammation and preventing recurrences.- - - - - - - - - - ranking = 0.67925648807984keywords = ocular, eye (Clic here for more details about this article) |
10/172. liver and brain mucormycosis in a diabetic patient type II successfully treated with liposomial amphotericin b.A case of liver and brain mucormycosis in a 73-y-old diabetic patient is described. The patient presented with fever and a moderate, tender hepatomegaly and a C/T scan examination of the abdomen and brain showed multiple hepatic and cerebral nodular lesions. The largest of the liver lesions was aspirated and broad hyphae of mucor were demonstrated in the purulent material obtained. The patient was treated successfully (for 40 d) with intravenous liposomal amphotericin b and then with itraconazole for 3 months. To our knowledge, this is the first case of a diabetic patient with both liver and brain mucormycosis who has been treated successfully.- - - - - - - - - - ranking = 1.2keywords = mycosis (Clic here for more details about this article) |
