Infantile generalized pustular psoriasis: Successful disease control with intermittent etretinate

Infantile generalized pustular psoriasis is a rare form of psoriasis and the best treatment is controversial. We experienced a 2‐year‐old female with erythema on her neck and axilla starting at 3 months of age. She presented with recurrent annular and geographic scaly erythema with a few pustules on the neck, precordium and axilla, but no fever. The histopathology revealed subcorneal neutrophilic infiltration and microabscesses without Kogoj's spongiform pustules. The initial diagnosis was subcorneal pustular dermatosis. However, she developed widespread geographic erythema and numerous pustules over her entire body with a fever when she got a cold. A second skin biopsy revealed monolocular pustules and Kogoj's spongiform pustules in the subcorneal layer. Etretinate was administrated after a diagnosis of pustular psoriasis was made and her condition improved gradually. The choice of treatment depends on patient age, general condition and the disease severity.     

The relation between EEG and mental development following cardiac surgery performed under simple deep hypothermia in children

In order to assess the accuracy of electroencephalography (EEG), in children who have undergone cardiac surgery under simple deep hypothermia, the relation between IQ or schoolwork achievement and the duration of circulatory arrest was investigated in 75 such children. Abnormal preoperative EEG's were found in 16 per cent of the children while abnormal postoperative EEG's were found in 17 per cent. The children were divided into 4 groups, according to pre- and postoperative EEG results. Schoolwork achievement scores ranged between 3.0 and 3.2, the difference among the groups being insignificant. Moreover, no significant shift in IQ was found among the groups. Finally, regarding the number of children who were able to go on to a higher level of education, including high school the college or university, again no significant differences were found among the 4 groups. In a comparison with the number of such children in neighboring Nagasaki prefecture able to continue on to a higher level of education, no significant differences were seen either. The findings and statistics of this investigation therefore indicate that pre- and postoperative EEG's are not always a reliable reference for assessing the prognosis of cerebral activity.     

Quality control for MHTS region and possibility of the standardization]

There is a final purpose of the standardization of the external quality control for the resolution of the difference between facilities. Two solutions are promoted in order to unify the evaluation level. They are that it unifies the reference value and common evaluation method used common display. However, it is the prior settlement that there is some a problem on both method and that absolute value is made to agree using standard substance.     

Pericardio-peritoneal drainage using a subcostal approach

A 56-year-old man admitted to our hospital for cardiac tamponade due to dilated cardiomyopathy did not respond to treatment by usual medical means or surgery. Pericardio-peritoneal drainage was conducted using a subcostal approach. Seven months later, the patient remains well and free of signs of pericardial tamponade. This method has proved to be safe and effective in patients with persistent massive pericardial effusion.     

Impact of smoking habit on medical care use and its costs: a prospective observation of National Health Insurance beneficiaries in Japan.

BACKGROUND: To quantify excess medical use associated with smoking, a large prospective cohort study is needed. The authors examined the impact of smoking on medical care use in a large population-based cohort with an accurate data collecting system in Japan. METHOD: The data were derived from a 30-month prospective cohort study of 43,408 National Health Insurance beneficiaries aged 40--79 years living in a rural Japanese community. The smoking habit of beneficiaries was assessed in a baseline survey at the end of 1994. Medical care use and its costs were monitored by linkage with the National Health Insurance claim history files since January 1995. RESULTS: Male smokers incurred 11% more medical costs (after adjustment for age, physical functioning status, alcohol consumption, body mass index and average time spent walking) than 'never smokers' but for female smokers and never smokers the costs were almost the same. This difference was mainly attributable to increased use of inpatient medical care among smokers, especially in males, where per month cost of inpatient care was 33% higher in smokers. Age-group specific analysis in men showed that excess mortality and excess medical cost ratio for smokers peaked in those aged 60--69 years. CONCLUSIONS: Smokers consume excess medical care. Among the population aged 45 years and over, about 4% of total medical costs were attributable to smoking. To pursue both better health and lower medical costs for the nation, a comprehensive programme to reduce tobacco use is needed.     

Comparison of characteristics between frequent participants and non-participants in screening program for stomach cancer.

To clarify the differences in characteristics between participants and non-participants in the screening program for stomach cancer, life-style and medical histories were compared among 20, 169 subjects who lived in an urban area (Sendai) and a rural area (Wakuya and Tajiri) in Miyagi Prefecture, Japan. All subjects were classified into three groups according to the frequency of participation in the screening program during the last 5 years; i.e., frequent participating group (FPG) for 4 or 5 times, reference group (RG) for 1-3 times and non-participating group (NPG) for 0 times. Subjects in the FPG consumed more milk and green-yellow vegetable whereas those in the NPG consumed less these foods. The age-adjusted proportions of present smokers were higher in the NPG but lower in the FPG significantly. The proportions of subjects who had parental histories of all cancers and stomach cancer and past history of gastro-duodenal ulcer were higher in the FPG and lower in the NPG. To control influences among the variables a stepwise multiple regression analysis was done, and it revealed that smoking and parental history of cancers were strong predictors to explain the frequency of participation.     

Evaluation of cardiac autonomic nerves by iodine-123 metaiodobenzylguanidine scintigraphy and ambulatory electrocardiography in patients after arterial switch operations

The autonomic cardiac nerves reach the heart after passing through the vicinity of the aortic root and the pulmonary trunk. The arterial switch operation (ASO) completely transects the ascending aorta and the pulmonary trunk. Therefore, this surgical procedure virtually denerves the heart. Cardiac sympathetic denervation and reinnervation were evaluated in patients after ASO using iodine-123 metaiodobenzylguanidine (MIBG) myocardial scintigraphy and parasympathetic denervation and reinnervation using ambulatory electrocardiography [Holter electrocardiogram (ECG)]. MIBG scintigraphy was performed in 14 patients who underwent ASO (ASO group) and 3 patients who underwent other open heart surgery (control group). All patients in the ASO group underwent the operation in the neonatal or infantile period. Planar and single photon emission computed tomography (SPECT) images of the myocardium were obtained. Defect score was determined by the SPECT images as a semi-quantitative index. The mean interval between ASO and MIBG scintigraphy was 25.6 +/- 14.6 months. Holter ECG was also performed in 14 patients in the ASO group and 19 age-matched normal children. The Holter ECGs were plotted on a Lorenz plot. The H index, which is related to vagal tone for the cardiovascular system, was calculated from the R-R intervals. The mean interval between the ASO and Holter ECG was 8.3 +/- 9.7 months. MIBG scintigraphy in the control group demonstrated an almost normal homogeneous tracer uptake, but showed extremely reduced tracer uptake and significantly higher defect score in the ASO group. The extent and degree of the reduction of MIBG uptake improved with time after the ASO. The heart-to-mediastinum MIBG count ratio tended to increase with time. The H index of the ASO group was lower than that of normal children (< 12 months: Control group 0.0280 +/- 0.0068 vs ASO group 0.0219 +/- 0.0083), and gradually increased with time (1-3 years: 0.0470 +/- 0.0157 vs 0.0314 +/- 0.0124). These results indicate that MIBG scintigraphy reflects the presence of sympathetic denervation and the possibility of reinnervation after ASO, and that H index reflects the presence of parasympathetic denervation and the possibility of reinnervation after ASO. These are simple and useful methods for assessing the extent and degree of autonomic denervation and reinnervation.
