The importance of bacterial superantigens produced by Staphylococcus aureus in the treatment of atopic dermatitis using povidone-iodine.

Atopic dermatitis (AD) is frequently associated with intestinal and cervical lesions. Staphylococcus aureus produces many kinds of toxins, the bacterial superantigens. The detection rate of toxins was 80.1% from 196 S. aureus strains. Neurological examinations revealed abnormalities in 59 out of 81 AD patients. Cervical magnetic resonance imaging (MRI) was performed in 46 patients randomly and showed abnormal findings in 38 of these patients. In 23 patients who underwent MRI and duodenal biopsy, 3 were found to be normal neurologically and 2 patients showed normal duodenal tissue. However, 18 patients had abnormal findings both on neurological examination and in duodenal tissue. Serial duodenal biopsy tests were performed in 10 AD patients. In 5 patients, the findings of chronic duodenitis disappeared after the therapy with povidone-iodine. These data indicate that the therapy was effective not only for the skin lesions, but improved gastrointestinal tract lesions and cervical myelopathy, by eradicating bacterial superantigens.

Assessment of myocardial perfusion and fatty acid metabolism in a patient with Churg-Strauss syndrome associated with eosinophilic heart disease.

Churg-Strauss syndrome is characterized by asthma, eosinophilia and systemic necrotizing vasculitis; cardiac involvement (ie, eosinophilic heart disease) is the major cause of morbidity and mortality, although there are no reports of an association between left ventricular dysfunction because of eosinophilic heart disease and myocardial blood flow or myocardial fatty acid metabolism. A patient presented with Churg-Strauss syndrome associated with eosinophilic heart disease that had progressed to dilated cardiomyopathy. Coronary angiography, thallium-201 ((201)Tl) and iodine-123 beta-methyl-iodophenyl pentadecanoic acid ((123)I BMIPP) myocardial single photon emission computed tomography (SPECT) were performed to evaluate left ventricular dysfunction. Although coronary angiography was normal and (201)Tl SPECT showed no apparent image defect, (123)I BMIPP SPECT showed diffuse decreased accumulation, excepting the apex. The left ventricular dysfunction in patients with eosinophilic heart disease is associated with impaired myocardial fatty acid metabolism rather than with impaired myocardial blood flow.

n-3 long-chain FA decrease serum levels of TG and remnant-like particle-cholesterol in humans.

A large number of papers have reported that administration of n-3 FA reduced serum TG concentrations in hypertriglyceridemic patients. However, few studies have examined the effect of n-3 FA on serum concentrations of remnant-like particle (RLP) cholesterol. Volunteers (n = 41) whose serum TG concentrations were 100-300 mg/dL were recruited and randomly assigned to either an n-3 FA group or a control group with stratification by sex, age, and serum TG level in a double-blind manner. The subjects in the n-3 FA group were administered 125 mL of fermented soybean milk with fish oil containing 600 mg of EPA and 260 mg of DHA/d for 12 wk. The controls consumed control soybean milk with olive oil. Fasting blood samples were obtained before the start of administration and at 4, 8, and 12 wk. EPA concentrations in red blood cells increased significantly in all but one subject in the n-3 FA group, with no significant changes in the control group. TG levels decreased more in the n-3 FA group than in the control group at weeks 4 (P < 0.05), 8 (P < 0.01), and 12 (P < 0.05) with their baseline as covariate. RLP cholesterol levels decreased more in the n-3 FA group than in the control at weeks 8 (P < 0.01) and 12 (P < 0.05) with their baseline as covariate. The groups did not differ in the other lipid levels. It is likely that n-3 long-chain FA may exert anti-atherosclerotic effects by lowering serum TG and RLP-cholesterol levels even at the dose of 860 mg/d.

Localized necrotizing angiitis of the ileum.

A 20-year-old woman was hospitalized repeatedly because of intermittent bouts of intestinal obstruction and the symptoms usually improved with conservative treatments. One year after the first admission the patient was hospitalized in emergency and a laparotomy revealed a circular stricture with a pinhole perforation in the ileum. Histological sections of the stricture showed the characteristic features of microscopic polyangiitis varying from active to resolving stages, which were localized in the ileum. Fibrinoid necrosis, fibroblastic and fibrous proliferation of the intima and fibrous replacement of the media with a variable pan- and perivascular inflammatory cell infiltrate were characteristic in the muscular arteries and arterioles. Vascular occlusion by pale eosinophilic, fibrillar-like materials resembling livedo racemosa of the skin, was noticed in the small arterioles and capillaries. Under no prophylaxis, the postoperative course was uneventful with no recurrence of the illness at an 18-month follow up. The pathological alterations were distributed focally, occasionally segmentally, and haphazardly, and required detailed examination by stepwise sections for the histological diagnosis.

Lung abscess caused by Actinomyces odontolyticus.

A 64-year-old woman with periodontal disease was admitted because of fever, right chest pain, and bloody sputum. Her chest radiograph revealed a nodular shadow in the right middle lung fields. From the results of a needle aspiration biopsy, she was diagnosed with a lung abscess due to Actinomyces odontolyticus (A. odontolyticus) and Streptococcus spp. The patient improved quickly with antibiotics. To our knowledge, only nine cases of pulmonary infection due to A. odontolyticus have been reported, and we report the first case in Japan. Although respiratory disease caused by A. odontolyticus is rare, the association of this organism should be considered even in healthy individuals.

[Role of public hospitals regarding the support of patients at home].

Eight sickbeds for the support of patients at home were established in Chiba Municipal Hospital in response to a request from the Chiba City Medical Association in 1997. These sickbeds were run by physicians and nurses in the hospital and nurses from Chiba City Public Health Center to promote a tight relation among the medical care, the health care and the public welfare systems. The role of the public health nurses is to receive and manage the documents of the patients from regional medical practitioners and to communicate with the related organizations. These sickbeds were set up to offer medical care, educational teaching to the family, and the social environment to support the patients at home. The patients, who were consulted by regional medical practitioners, were pre-registered by them. The length of stay at the hospital was limited to 2 weeks. The number of patients who were registered and hospitalized increased every year: thus 374 patients receiving treatment from 44 medical practitioners have already been registered. The average age of the patients was 81.1 and almost all of the patients were sick in bed for the whole day at home. Sixty-three patients were hospitalized making use of those sickbeds this year. Further promotion of the relation among the organizations involved in medical care, health care, and welfare is very important to support the patients to be able to stay at home.
