1/82. Endoscopic sinus surgery in the management of mucormycosis.This is a report of the use of endoscopic sinus surgery in the management of three patients diagnosed with rhino-orbital or rhino-orbito-cerebral mucormycosis. A retrospective review was performed of the clinical examinations and imaging studies of three patients who underwent endoscopic sinus surgery as part of their therapy for mucormycosis. In addition to endoscopic surgery, all patients had aggressive control of underlying risk factors (diabetes mellitus, immunosuppression) and prolonged intravenous amphotericin b therapy. All three patients survived and avoided orbital exenteration. In selected patients with rhino-orbito-cerebral mucormycosis, endoscopic techniques can play a valuable role in diagnosis and management.- - - - - - - - - - ranking = 1keywords = mucormycosis (Clic here for more details about this article) |
2/82. Rhinocerebral mucormycosis in patients with burns: case report and review of the literature.mucormycosis is an opportunistic infection most commonly occurring in patients with impaired host defenses or diabetes mellitus. In patients with burns the rhinocerebral form is rare, and mucormycotic infections more commonly involve the cutaneous burn wound. Both forms are associated with a high mortality rate that increases with delays in treatment. The initial management of these types of infections includes vigorous glucose control, correction of acidosis, and the administration of systemic antifungal agents such as amphotericin b. The rhinocerebral form of mucormycosis is extremely virulent and may warrant the use of interstitial and intraventricular antifungal therapy. Despite these measures, the mainstay of treatment for both forms of mucormycosis is the extensive surgical debridement of all infected and necrotic tissue.- - - - - - - - - - ranking = 0.85714285714286keywords = mucormycosis (Clic here for more details about this article) |
3/82. Rhinocerebral mucormycosis: a case of a rare, but deadly disease.Rhinocerebral mucormycosis is a rare fungal infection of the nasal cavity and sinuses that can spread to the orbits and cranium within days. Its presentation can be confused with those of sinusitis, viral infections, diabetic ketoacidosis, or carotid sinus thrombosis, and it is often missed at early presentation. survival is directly linked to early detection and treatment. We present a case of rhinocerebral mucormycosis and discuss the literature on its early signs and symptoms, pathophysiology, and treatment options.- - - - - - - - - - ranking = 0.85714285714286keywords = mucormycosis (Clic here for more details about this article) |
4/82. survival after rhino-orbital-cerebral mucormycosis in an immunocompetent patient.OBJECTIVE: Rhino-orbital-cerebral mucormycosis is usually associated with a poor prognosis and is almost exclusively seen in immunocompromised patients. We report the third documented case of rhino-orbital-cerebral mucormycosis caused by Apophysomyces elegans (a new genus of the family Mucoraceae first isolated in 1979) in an immunocompetent individual. Orbital exenteration and radical debridement of involved adjacent structures combined with intravenous liposomal amphotericin resulted in patient survival. DESIGN: Interventional case report. METHOD: A 59-year-old immunocompetent white man sustained a high-pressure water jet injury to the right inner canthus while cleaning an air conditioner filter. He later had "orbital cellulitis" develop that did not respond to antibiotics and progressed to orbital infarction. Imaging studies and biopsy results led to a diagnosis of mucormycosis. Tissue culture grew Apophysomyces elegans, a new genus of the family Mucoraceae first isolated in 1979. Orbital exenteration and radical debridement of involved adjacent structures, combined with intravenous liposomal amphotericin, resulted in patient survival. RESULTS: After orbital exenteration and debridement of involved adjacent structures along with intravenous liposomal amphotericin, our patient has remained free from relapse with long-term follow-up. CONCLUSIONS: The agent causing this case of rhino-orbital-cerebral mucormycosis (Apophysomyces elegans) contrasts with the three genera most commonly responsible for mucormycosis (rhizopus, Mucor, and absidia) in that infections with this agent tend to occur in warm climates, by means of traumatic inoculation, and in immunocompetent patients. Rhino-orbital-cerebral mucormycosis should be considered in all patients with orbital inflammation associated with multiple cranial nerve palsies and retinal or orbital infarction, regardless of their immunologic status. A team approach to management is recommended for early, appropriate surgery and systemic antifungal agents.- - - - - - - - - - ranking = 1.4285714285714keywords = mucormycosis (Clic here for more details about this article) |
5/82. Acute subdural hematoma and intracerebral hemorrhage. Rare complications of rhinocerebral mucormycosis.Rhinocerebral mucormycosis is a short-term and often rapidly lethal fungal disease. It is generally seen in uncontrolled cases of diabetes with ketoacidosis. This case exhibits many of the features of a typical fulminating rhinocerebral mucormycosis. However, the fatal complications of acute subdural hematoma and massive intracerebral hemorrhage due to rupture of aneurysm, as demonstrated by angiography, are unique clinical manifestations of patients with rhinocerebral mucormycosis.- - - - - - - - - - ranking = 1keywords = mucormycosis (Clic here for more details about this article) |
6/82. Identification of the asexual state of rhizopus species on histologic tissue sections in a patient with rhinocerebral mucormycosis.mucormycosis is an infection caused by a group of fungi in the order mucorales in the phylum Zygomycota. The most well-known form of this disease is rhinocerebral mucormycosis, which usually develops in diabetic or immunocompromised patients. The fungal hyphal elements are easily detected in biopsy specimens by direct or histologic examination. However, the confirmatory identification of the genus or species requires culture of the specimen. This article presents a case of rhinocerebral mucormycosis in which presumptive identification of the genus was made without microbiologic cultures and was based on the extraordinarily rare appearance of fungal sporangia and sporangiospores in histologic tissue sections. Identification of these structures allowed an early and accurate diagnosis of rhinocerebral invasive mucormycosis.- - - - - - - - - - ranking = 1keywords = mucormycosis (Clic here for more details about this article) |
7/82. 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 = 0.85714285714286keywords = mucormycosis (Clic here for more details about this article) |
8/82. Rhinocerebral mucormycosis diagnosis by aspiration cytology.Rhinocerebral mucormycosis is a rapidly progressing, often fatal fungal infection that occurs commonly in diabetics and immunocompromised individuals. We present 2 cases of rhinocerebral mucormycosis with a paranasal mass. One patient had an intracranial extension. Nasal scrapings and fine-needle aspiration cytology (FNAC) of the paranasal masses showed fungal hyphae morphologically resembling Mucor. Surgical material showed features of mucormycosis. FNAC and scrape smears can give a conclusive diagnosis of mucormycosis, and the patient can be treated with appropriate antifungal therapy and surgical debridement. Preoperative cytology is an effective technique to establish a diagnosis of mucormycosis and obviates the need for a preoperative biopsy.- - - - - - - - - - ranking = 1.2857142857143keywords = mucormycosis (Clic here for more details about this article) |
9/82. mucormycosis in a transplant recipient.mucormycosis classically occurs in patients who have uncontrolled diabetes who develop rhinocerebral disease. A fatal case of rhinocerebral infection caused by rhizopus arrhizus in a 53-year-old man who had received a renal homograft three years previously is reported. Only five similar cases have been documented, all since 1970. Although direct smears of the purulent nasal exudate revealed the presence of numerous Gram-negative bacilli, later identified as haemophilus influenzae, the diagnosis of mucormycosis was made by demonstrating the typical broad, nonseptate branched hyphae in the necrotic tissue obtained by surgical debridement of the paranasal sinuses. culture of this material revealed growth of mold-like fungus which, upon direct microscopic examination, showed sporangiophores bearing spherical sporangia arising directly from a cluster of root-like structures of rhizoids. Despite the immediate institution of therapy with amphotericin b postoperatively, the patient died 48 hours later. Subsequently, the rhizopus isolated was shown to be resistant to both amphotericin b and 5-fluorocytosine. The present case and two others stress the importance of an aggressive diagnostic approach to patients suspected of having mucormycosis, because the usual microbiologic technics are frequently, inexplicably, unsuccessful, and possibly even misleading in this disease.- - - - - - - - - - ranking = 0.28571428571429keywords = mucormycosis (Clic here for more details about this article) |
10/82. head and brain scan findings in rhinocerebral mucormycosis: case report.brain and bone scan findings in two patients suffering from rhinocerebral mucormycosis following kidney transplantation are presented. Two patients who had had kidney transplants and were sustained for over a month on immunosuppressive drugs developed a rare type of opportunistic infection--mucormycosis. They were examined in various stages of their disease. Special attention was paid to the scintillagraphic findings.- - - - - - - - - - ranking = 0.85714285714286keywords = mucormycosis (Clic here for more details about this article) |
