1/98. Nontraumatic clostridial myonecrosis.We describe three cases of nontraumatic clostridial myonecrosis seen at the Victorian Institute of forensic medicine. Nontraumatic clostridial myonecrosis is an uncommon and often fatal condition that requires immediate institution of appropriate medical and surgical therapy. It is most commonly caused by clostridium perfringens and clostridium septicum and is associated with gastrointestinal and hematologic malignancies, diabetes mellitus, and peripheral vascular disease. The clinical features include a rapidly evolving acute illness with severe pain, marked tachycardia, and brawny discoloration of the skin with bullae formation and crepitus, followed by hypotension and acute renal failure. Features at autopsy include reddish brown skin discoloration with bullae formation and necrotic skeletal muscle. Radiographs may be of use prior to the postmortem in detecting gas within the soft tissues. Gram stain and microbiologic culture are important in establishing a definitive diagnosis; although the major factors in suggesting the diagnosis are the recognition of the typical clinical history and macroscopic autopsy findings.- - - - - - - - - - ranking = 1keywords = diabetes mellitus, diabetes, mellitus (Clic here for more details about this article) |
2/98. 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 = 1keywords = diabetes mellitus, diabetes, mellitus (Clic here for more details about this article) |
3/98. Adrenal vein thromboses in an infant of diabetic mother.Maternal diabetes is common condition complicating pregnancy and may have serious consequences for the offspring. We report on an infant of a mother with multisubstance abuse and poorly controlled type I diabetes with complications that include multifocal fetal myocardial infarcts, macrosomia, hypoxic encephalopathy and islet cell hyperplasia, and bilateral adrenal vein thromboses with necrosis, a relatively rare complication of maternal diabetes.- - - - - - - - - - ranking = 0.66306213034486keywords = diabetes (Clic here for more details about this article) |
4/98. A fatal case of craniofacial necrotizing fasciitis.A case of fatal craniofacial necrotizing fasciitis is described in a 72-year-old diabetic woman and management is discussed. Progressive infection of the eyelids occurred with involvement of the right side of the face. Computed tomography revealed soft tissue swelling. Antibiotic treatment was started and debridement performed; histopathology showed acute inflammation and thrombosis of the epidermis and dermis. Despite treatment, scepticemia occurred, resulting in death less than 48 h after presentation. At this time extensive necrosis had developed in the superficial fascia with undermining and gangrene of surrounding tissues. streptococcus and staphylococcus were the pathogens involved. Poor prognosis in similar patients has been associated with extensive infection, involvement of the lower face and neck, delayed treatment, advanced age, diabetes and vascular disease.- - - - - - - - - - ranking = 0.22102071011495keywords = diabetes (Clic here for more details about this article) |
5/98. Cervical necrotizing fasciitis of odontogenic origin: a case report and review of 12 cases.PURPOSE: This article reviews the demographics, presentation, cause, clinical findings, and treatment of 12 cases of cervical necrotizing fasciitis of odontogenic origin. patients AND methods: A retrospective chart review of 12 cases treated between 1987 and 1997 was done. RESULTS: Most cases resulted from an abscessed mandibular molar. The most common significant medical conditions in the patient's history were diabetes, hypertension, obesity, and substance abuse. All patients were treated surgically within 24 hours of admission. Hyperbaric oxygen (HBO) was used as adjunctive treatment in all cases. The average length of hospital stay was 31 days. All patients recovered. CONCLUSION: Early surgical intervention and the use of HBO decreases morbidity and improves the clinical outcome.- - - - - - - - - - ranking = 0.22102071011495keywords = diabetes (Clic here for more details about this article) |
6/98. enteritis necroticans (pigbel) in a diabetic child.BACKGROUND AND methods: enteritis necroticans (pigbel), an often fatal illness characterized by hemorrhagic, inflammatory, or ischemic necrosis of the jejunum, occurs in developing countries but is rare in developed countries, where its occurrence is confined to adults with chronic illnesses. The causative organism of enteritis necroticans is clostridium perfringens type C, an anaerobic gram-positive bacillus. In December 1998, enteritis necroticans developed in a 12-year-old boy with poorly controlled diabetes mellitus after he consumed pig intestines (chitterlings). He presented with hematemesis, abdominal distention, and severe diabetic ketoacidosis with hypotension. At laparotomy, extensive jejunal necrosis required bowel resection, jejunostomy, and ileostomy. Samples were obtained for histopathological examination. Polymerase-chain-reaction (PCR) assay was performed on paraffin-embedded bowel tissue with primers specific for the cpa and cpb genes, which code for the alpha and beta toxins produced by C. perfringens. RESULTS: Histologic examination of resected bowel tissue showed extensive mucosal necrosis, the formation of pseudomembrane, pneumatosis, and areas of epithelial regeneration that alternated with necrotic segments--findings consistent with a diagnosis of enteritis necroticans. Gram's staining showed large gram-positive bacilli whose features were consistent with those of clostridium species. Through PCR amplification, we detected products of the cpa and cpb genes, which indicated the presence of C. perfringens type C. Assay of ileal tissue obtained during surgery to restore the continuity of the patient's bowel was negative for C. perfringens. CONCLUSIONS: The preparation or consumption of chitterlings by diabetic patients and other chronically ill persons can result in potentially life-threatening infectious complications.- - - - - - - - - - ranking = 1keywords = diabetes mellitus, diabetes, mellitus (Clic here for more details about this article) |
7/98. Nasal alar necrosis.OBJECTIVE: To describe an unrecognized clinical entity, nasal alar necrosis, and propose recommendations regarding the diagnosis, pathophysiology, and management of these cases. STUDY DESIGN: Retrospective review of four patients with this condition. methods: Histories, treatments, and outcomes were evaluated using office and hospital chart data. RESULTS: We noted that three patients had prior trauma or surgery, other than to the nose, in the head and neck region. All four patients had comorbidities such as diabetes, hypothyroidism, depression, or tobacco abuse. Three patients had sensory deficits over the distribution of the maxillary nerve, and three volunteered that they had a habit of picking the crusted wound. Two patients improved over several months with aggressive wound care. One patient refused treatment and another underwent successful reconstruction. CONCLUSIONS: After malignant and granulomatous diseases were ruled out, our evaluations suggested that the pathogenesis was multifactorial including several factors alone or in combination, such as, hypoesthesia, self-mutilation, and an inadequate blood supply. Deficits in vascularity and sensory innervation must be considered as potential obstacles in reconstruction. Psychological problems causing factitious wounding may complicate therapeutic interventions.- - - - - - - - - - ranking = 0.22102071011495keywords = diabetes (Clic here for more details about this article) |
8/98. Raynaud's phenomenon, anticentromere antibodies, and digital necrosis without sclerodactyly: an entity independent of scleroderma?We describe 4 women of 43, 73, 84, and 86 years with Raynaud's phenomenon, severe digital necrosis, and high serum levels of anticentromere antibodies without skin thickening or internal organ sclerosis. Investigations revealed no diabetes or arterial vascular disease leading to arterial obstruction. Histologic examination did not show any dermal sclerosis or calcinosis. The intravenous infusions of prostaglandin reversed the ischemic lesions in 3 patients. These cases suggest that the triad Raynaud's phenomenon, anticentromere antibodies and necrosis of digits without sclerodactyly and sclerosis of internal organ should be considered as an entity distinct from scleroderma with sclerosis. For this entity we propose the name RACAND syndrome.- - - - - - - - - - ranking = 0.22102071011495keywords = diabetes (Clic here for more details about this article) |
9/98. Idiopathic giant-cell granulomatous hypophysitis. Report of a case with autopsy follow-up.Idiopathic granulomatous inflammation of the pituitary gland occurs rarely, and is usually identified as an incidental finding at autopsy. However, it may present during life as a mass lesion that clinically mimics other more common pituitary gland lesions. We report a 54-year-old woman presenting with acute onset diabetes insipidus whose MRI showed a 1.1 cm pituitary mass, with infundibular thickening and meningeal enhancement. biopsy demonstrated granulomatous hypophysitis with multinucleate histiocytes. Special studies for infectious organisms were negative. The patient's disease progressed following biopsy, causing complete loss of vision in the right eye. This responded to high-dose steroids and local lowdose radiation. She later developed an acute inferior myocardial infarction. Laboratory tests failed to demonstrate an underlying autoimmune process. While recovering from this myocardial infarction, she succumbed to pulmonary embolism. autopsy revealed moderate residual chronic infundibular inflammation. No evidence of systemic or residual pituitary granulomatous disease was identified. To the best of our knowledge, this is the first case of idiopathic granulomatous hypophysitis initially diagnosed by biopsy to have post-mortem neuropathologic examination.- - - - - - - - - - ranking = 0.22102071011495keywords = diabetes (Clic here for more details about this article) |
10/98. Hepatic necrosis with cholestasis induced by long-term voglibose administration.A 76-year-old woman admitted to our hospital for jaundice had been treated for diabetes mellitus with insulin for 9 years and voglibose had been added for the 39 months preceding admission. Elevated serum bilirubin and transaminase concentration began to normalize with initiation of corticosteroid treatment 1 week after discontinuation of voglibose. In the in vitro testing of the patient's peripheral blood, lymphocytes showed stimulation by voglibose. In dramatic contrast to an initial liver biopsy specimen that demonstrated cholestasis with submassive and zonal necrosis, the follow-up specimen was normal 1 year later. We believe that patients treated with voglibose should be monitored long-term with monthly determinations of transaminases and bilirubin in serum.- - - - - - - - - - ranking = 1keywords = diabetes mellitus, diabetes, mellitus (Clic here for more details about this article) |
