Mucormycosis is an opportunistic infection that has been mainly described in adults with preexisting disease affecting immune status, eg, diabetes, leukemia, lymphoma, and renal failure on peritoneal dialysis. Few cases have been described in neonates. The presentation of mucormycosis as a cause of neonatal necrotizing enterocolitis is an unusual phenomenon. Three fatal cases of mucormycosis of the gut in premature infants in the period 1990 to 1991 are described. It is not clear whether this should be considered a separate disease or a variant of necrotizing enterocolitis. All three patients died soon after laparotomy from septic shock and the histological diagnosis of mucormycosis was made too late for effective chemotherapy.

Topical and systemic steroids have proven to be invaluable agents in the treatment of a wide range of disorders, but their use is not without potential complications. Before initiation of therapy with systemic steroids, a personal or family history of cataracts, glaucoma, hypertension, diabetes, hyperlipidemia, renal stones, peptic ulceration, and current infection or pregnancy should be ascertained, because these patients have an increased risk of complications. Prior to long-term therapy with systemic steroids, blood pressure measurement, tuberculin skin test, and anergy panel are recommended. Monthly follow-up may include measurements of weight, blood pressure, electrolytes, and blood sugar and guaiac testing of the stool. To prevent the ocular complications of steroid therapy, routine screening is indicated (Table 1). Screening for cataracts, which occur most commonly as a sequela of continuous systemic steroid use, may be performed by slit-lamp examinations conducted three or four times a year for patients on long-term therapy and twice a year for patients taking intermittent topical ocular or systemic steroids. Glaucoma is more often associated with topical ocular or periocular steroids than with systemic steroids; recommended screening includes a baseline intraocular pressure measurement, then routine pressure measurements taken every few weeks initially, then every few months. Ocular rebound inflammation may develop secondary to rapid tapering or abrupt discontinuation of topical ocular steroid use and is best prevented with gradual tapering. Opportunistic infections of the eye include bacterial, viral, and fungal infections and are most often associated with the use of topical ocular steroids. Ophthalmologic evaluation is indicated promptly if patients treated with ocular steroids develop ocular discharge, pain, photophobia, or redness.

Mucormycosis is infrequently encountered in the pediatric population in any of its forms (nasopharyngeal, disseminated, pulmonary, or cutaneous) and generally is associated with the immunocompromised host. We present an adolescent with poorly controlled diabetes mellitus who developed a progressive skin lesion 3 weeks after a motor vehicle accident. Rhizopus species was isolated from the lesion, and the biopsy revealed a fungal vasculopathy. Control of her diabetes, aggressive surgical intervention and a 10-day course of antifungal therapy (amphotericin B) resulted in a favorable outcome. This article illustrates the importance of considering cutaneous fungal infections, especially those in the class zygomycetes, in the diabetic patient with unusual, severe or persistent skin lesions. Early recognition is essential in order to avoid morbidity and mortality from this unusual opportunistic infection.

Mucormycosis is an opportunistic infection caused by fungi of the order Mucorales. The commonest clinical form is rhinocerebral mucormycosis, which has been described as characteristically complicating diabetes mellitus and leukemia. Three patients with rhinocerebral mucormycosis complicating renal transplantation are described, and 11 additional cases recorded in the English-language medical literature are reviewed. The mean age of the 14 patients was 36 years, and the ratio of males to females was 1.8:1. Diabetes mellitus was present in only five patients, and polycystic kidney was the most common underlying renal disease. Most kidney grafts were obtained from cadavers. Eight patients had evidence of graft rejection, and the majority had been receiving corticosteroids and azathioprine. The initial manifestations of infections became evident two days to four years after transplantation (median, two months). Facial swelling, tissue necrosis, and cranial nerve involvement were common. Seven of 14 cases occurred in Israel, a finding suggesting the intervention of local factors. Despite antifungal and/or surgical therapy, nine patients died as a consequence of the infection days to months after diagnosis. Although a rare complication, rhinocerebral mucormycosis remains a serious threat to the kidney transplant recipient.

Persistent diabetes was induced in male Slc:ddY mice by a single intraperitoneal injection of 200 mg/kg streptozotocin (STZ). In these mice, the numbers of aerobic gram-negative bacilli, staphylococci (including micrococci), and streptococci increased, while those of other bacteria were almost unchanged in both oral and caecal floras. The mice were vulnerable to oral infection of Salmonella enteritidis, intranasal infection of Klebsiella pneumoniae and Serratia marcescens, and contact infection with mice infected with S. enteritidis and K. pneumoniae. These findings suggest that STZ-treated mice might be a useful model for investigating opportunistic infection.

Mucormycosis is an often-fatal opportunistic fungal infection caused by members of the class Zygomycetes (Phycomycetes), order Mucorales. Most cases are diagnosed by histologic examination, through the identification of mucormycotic hyphae in infected tissues. Chronic debilitating conditions accompanied by acidosis such as diabetes mellitus, as well as leukemia, lymphoma, and immunodeficient states, predispose to the development of this type of opportunistic infection. This report describes a hitherto undescribed finding, the presence of structures consistent with sporangia in tissue sections, in a case of pulmonary mucormycosis occurring in a nondiabetic patient with metabolic acidosis secondary to chronic salicylate poisoning.

Cutaneous infection of the thumb by a Syncephalastrum sp. is described in an adult male suffering from diabetic ketosis. The fungus was isolated from the skin and was found to produce arteritis in the dermal vessels. The patient died of diabetes mellitus without any associated systemic mycosis. Syncephalastrum in this case had occurred as an opportunistic infection.

Rhinocerebral phycomycosis is an uncommon opportunistic infection with ubiquitous fungi of the class Phycomycetes, starting in the nose and extending to the paranasal sinuses and then intracranially. The condition is often characterized by poor prognosis because of occlusion of the internal carotid artery. This disease is commonly associated with predispositions such as uncontrolled diabetes mellitus, which is the most common, immunosuppressive states and metabolic bankruptcy including leukemia, lymphoma, myeloma, malnutrition, uremic or diarrheal acidosis, severe burns, anemia, carcinoma, radiotherapy, liver cirrhosis, hemochromatosis, tuberculosis, septicemia, long-term medication of steroid, antibiotics and antimetabolite, drug addiction, cytotoxic drug administration and AIDS. Cases with unknown predisposition, however, have been infrequently reported in the literature. The authors report a case of rhinocerebral phycomycosis in which concurrence of Candida species instead of the above-mentioned common predispositions was considered a potential predisposition. To our knowledge, only 1 report in which Candida species are referred to as a potential predisposition for this disease has been previously issued. A 85-year-old man was admitted to our hospital on March 2, 1994 because of generalized convulsion. He had received a total extirpation of an ascending colon cancer in July 1993. On admission, physical inspection showed no abnormalities and neurological examination revealed obtunded consciousness without other abnormalities. He had no diabetes mellitus. Hematological and blood chemistry values were normal except for CA19-9 of 45 U/ml.(ABSTRACT TRUNCATED AT 250 WORDS)

Mucormycosis (phycomycosis, zygomycosis) is an acute opportunistic infection caused by a saprophytic fungus found in soil, bread molds, and decaying fruits and vegetables. Numerous predisposing risk factors are associated with mucormycosis, although most cases have been reported in poorly controlled diabetics or in patients with hematologic malignant conditions. This report presents two cases of oral mucormycosis. One case occurred in the maxilla in a patient with well-controlled diabetes. The other involved the mandible and overlying gingiva in a patient with acute myelogenous leukemia. A review of the literature concerning oral mucormycosis is also presented.

Pancreas transplantation has become a viable option for the patient wi th insulin-dependent diabetes mellitus with progressive renal failure. The most common type of pancreas transplantation is a simultaneous pancreas and kidney transplantation performed from a single cadaver donor (SPK). The next most common is pancreas transplantation after successful kidney transplantation (PAK). A few centers are performing pancreas transplantation alone (PTA) in diabetic recipients without renal disease but who have significant complications from their diabetes. Pancreas transplantation is associated with a higher morbidity than kidney transplantation alone. Most pancreas transplantation centers report a significant increase in acute rejection, which can lead to increased hospitalization and risk of opportunistic infection. In addition, the early era of pancreas transplantation was associated with significant surgical complications. However, with bladder drainage of the pancreas exocrine secretions, the surgical complication rate has decreased significantly. Despite medical and surgical complications, the overall results for pancreas transplantation are excellent, with 1 -year graft survival of 75% for SPK transplantations and 48% for PAK and PTA transplant recipients. The effects of a pancreas transplantation on the secondary complications of diabetes have been studied extensively. Most studies have shown a modest improvement in secondary complications with the exception of diabetic retinopathy. The major benefit of pancreas transplantation appears to be enhanced quality of life for patients successfully transplanted. For these reasons, the Kidney-Pancreas Committee of the American Society of Transplant Physicians believes the current results of pancreas-kidney transplantation justify its use as a valid option for insulin-dependent diabetic transplant recipients.
