Rhinocerebral mucormycosis (RCM) is a rare, fulminant fungal infection that usually occurs in diabetic or immunocompromised patients. The mortality rate has been reduced recently with the advent of amphotericin B combined with aggressive surgery. Eleven RCM patients have been treated over the past five years at Srinagarind Hospital. Eight had underlying diabetes, five had renal failure and three of them had both. In eight patients, the diagnosis was established by KOH preparation before histological confirmation. Only two cases revealed positive cultures for Rhizopus spp and Cunninghamella spp. All patients underwent surgical treatments (extensive debridement, 8 cases; sphenoidectomy, 7 cases; ethmoidectomy 8 cases; maxillectomy 5 cases and orbital exenteration, 6 cases). Amphotericin B was administered to all patients as soon as the diagnosis of RCM was made. Only three patients survived. Early diagnosis and cooperation among ophthalmologist, otolaryngologist and physician are the most important factors for the survival of patients with mucormycosis.

Fifty-nine cases of mucormycosis in dialysis patients have been reported to the registry (25 new cases and 34 previously reported cases). The presenting forms of mucormycosis included disseminated in 44%, rhinocerebral in 31%, and other forms in 25%. The diagnosis was made during life in only 39%, while the diagnosis was discovered at autopsy in 61% of the cases. The fungus, cultured in only 36%, was always Rhizopus. The infection was fatal in 86% of cases. No known risk factors for fungal infections, eg, diabetes mellitus, liver disease, splenectomy, neutropenia, steroid therapy, or other immunosuppressive therapy, were present in 70% of patients, but 78% of patients were being treated with deferoxamine. The role played by this drug and more particularly by its iron chelate, feroxamine, in the pathogenesis of mucormycosis in these patients is underscored. Because of this risk, deferoxamine therapy in dialysis patients should be limited to severe aluminum toxicity, the deferoxamine should be given at the lowest possible dose, and dialytic methods to augment the removal of feroxamine should be studied.

Pulmonarycosis is a rare disease, which refers to an infection by fungi belonging to the order Mucorales. This organism usually invades the skin, nose mouth, paranasal sinus, gastrointestinal tract, lung, brain, eyes and so forth. It usually occurs in patients with diabetes mellitus, hematological malignancy or other immunocompromised states. Until recently, this disease was rarely diagnosed before death. We report a case of pulmonary mucormycosis in a woman with poorly controlled diabetes mellitus. This is the first case in Taiwan of pulmonary mucormycosis diagnosed preoperatively and treated successfully by lobectomy only. Persistent pulmonary lesions resistant to antibiotic treatment in high risk patients should arouse the suspicion of mucormycosis. Prompt bronchoscopic examination, open lung biopsy and transthoracic pulmonary aspiration cytology and biopsy should be done. Surgical resection of localized lesions remains the treatment of choice.

Mucormycosis is a very serious fungal infection caused by habitual saprophytes of the human organism, in many cases concomitant with various pathological conditions marked by immunodepression. The rhinocerebral variant habitually accompanies ketoacidotic diabetes. We report a case of rhinocerebral mucormycosis in a subject free from immunodepression and non-diabetic, in apparently normal health. Following treatment with amphotericin B combined with 5-fluorocytosine and surgery, remission of the disease was finally secured and about one year after the last operation there are no sign of resumption.

Mucormycosis (synonymous with phycomycosis and zygomycosis) is a devastating fungal infection which usually involves patients with diabetes mellitus, often complicated by ketoacidosis, and malignant neoplasms, commonly leukemia and lymphoma. Clinical manifestations include rhinocerebral, pulmonary, disseminated, isolated cerebral, gastrointestinal and cutaneous disease. Common to all forms of mucormycosis is vascular invasion with production of necrotic tissue. The diagnosis is achieved by demonstrating broad, non-septate hyphae with right-angle branching in a tissue biopsy specimen. Successful treatment consists of early diagnosis, intensive systemic antifungal therapy with amphotericin B, aggressive surgical debridement and control of the underlying disease. In our experience with mucormycosis at Huntsville Hospital, the patients were immuno- compromised and the infection was restricted to the lung. Despite use of amphotericin B in all patients, the only one who survived underwent surgical section of infected tissue.

Mucormycosis is an uncommon infection caused by fungi of the order Mucorales. During an 8-year period, mucormycosis was diagnosed in 13 patients from three Madrid hospitals. There were 8 males and 5 females, with ages ranging from 21 to 75 years (mean 45 years). There were several underlying diseases, and 4 patients had more than one. Five had diabetes mellitus, 4 chronic renal failure, 2 acute myeloblastic leukemia, 2 were narcotic abusers and were infected by the human immunodeficiency virus (HIV), 1 had non-Hodgkin's lymphoma, 1 was a carrier of a renal allograft and 1 had systemic necrotizing vasculitis. There were different clinical presentations: rhino-orbital in 3, paranasal in 2, cutaneous in 2, pulmonary in 2, primary cerebral in 2, rhinocerebral in 1, and peritoneal in 1. The diagnosis was made during the first week in 6 patients, in the second week in 4, and it was delayed for more than one month in 2. Fresh examination of clinical samples was carried out in 3 patients and hyphae were visualized in all 3. Cultures were taken in 10 patients and they were positive in 7. All isolates were identified as Rhizopus sp. One patient died within 24 hours without being treated, 12 were treated with amphotericin B and 9 received surgical therapy. Six patients (46%) died. The involvement of central nervous system and the absence of surgical therapy were associated with a poor outcome. These results indicate that mucormycosis can develop in several clinical contexts and has a varying clinical presentation. It is a potentially curable infections when early diagnosed and appropriately treated.

Melioidosis is an infection of humans and animals caused by a gram-negative motile bacillus, Pseudomonas pseudomallei. Forty-nine patients with melioidosis complicating diabetes mellitus, collagen vascular disorders, leukemia/lymphoma, and other hematologic malignancies are described. Twenty-nine of these patients had disseminated/septicemic infection, two developed toxic shock syndrome, and one with AIDS experienced recrudescent melioidosis. Patients with disseminated melioidosis often have a variety of defects in cellular immunity both in vitro and in vivo. In humans with recrudescent melioidosis, cellular immunity can be transferred by a transfer factor and by levamisole, a cellular immunopotentiating agent. The results of the treatment of our patients with disseminated/septicemic melioidosis with antimicrobial agents in combination have been successful. In recent years, four cases of fungal arteritis due to Pythium species and one case of keratitis due to Pythium were seen. Almost all patients with fungal arteritis had thalassemia; all presented with pain in the lower extremities and gangrenous lesions of the toes. Pythium species, an aquatic Phycomycetes, was identified in these cases as a human pathogen on the basis of clinical features, pathologic findings, and--of greatest importance--the isolation of the etiologic fungi. These five cases with remarkably similar presentations exhibited certain similarities with and differences from cases of mucormycosis, entomophthoromycosis, and peniciliosis.

We present a 43-year-old patient with a history of immunodepression secondary to a renal transplant, chronic herpetic hepatitis and steroid diabetes, who showed sudden symptomatology suggestive of rhinocerebral mucormycosis, which was confirmed through cultures of the material obtained after a Caldwell-Luc operation of the affected sinus. Once the diagnosis was confirmed, a radical left superior maxillectomy was performed and medical treatment with progressive doses of amphotericin B was given. The patient improved markedly and left the hospital four months later.

Cerebral mucormycosis is a rare disorder caused by several genera of the family Mucoraceae. The genera Rhizopus, Absidia, and Mucor are the predominant pathogenic groups. Disease caused by these organisms usually complicates an underlying chronic illness, such as diabetes mellitus or malignancy. Cerebral involvement usually occurs from an ascending infection from the paranasal sinuses via the orbit and is usually associated with poorly controlled diabetes. The pulmonary system is the most common site of infection in patients with leukemia. Isolated cerebral mucormycosis not associated with head trauma or intravenous drug abuse is a rare disorder. We report what we believe to be the first successfully treated case of isolated cerebral mucormycosis in a patient with acute lymphocytic leukemia in remission.

A 48-year-old man receiving maintenance hemodialysis for 3 years and continuous ambulatory peritoneal dialysis for 1 year developed a clinical picture compatible with peritonitis. Three successive fluid cultures were negative, and only after filtration of a large volume of peritoneal fluid a fungus identified as a Rhizopus sp was isolated in cultures of the filtering devices. The same fungus was also isolated from the peritoneal catheter cuff. Intravenous amphotericin B was administered and both the abdominal and general conditions of the patient improved transiently. Twenty days after initiation of antifungal treatment, a clinical suspicion of intestinal perforation arose and an exploratory laparotomy was scheduled, but the patient died during the anesthetic induction. The patient never received deferoxamine; any conditions predisposing to mucormycosis, such as diabetes or immunosuppression, were also absent.
