Coping skills in Japanese women with eating disorders.

The aim of this study was to investigate coping skills in the different types of eating disorders in Japan. Groups of patients with eating disorders diagnosed with DSM-IV and 22 controls were studied. Coping skills were assessed with the Stress Coping Inventory. The mean Problem-focused coping score tended to be lower in the bulimia nervosa purging-type group (n = 20) than in the control group. The former group and the bulimia nervosa nonpurging-type group (n = 6) used significantly less planful problem solving and less positive reappraisal coping than the control group, while the anorexia nervosa restricting-type group of 11 tended to use less positive reappraisal, and the anorexia nervosa binge-eating/purging-type (n = 11) tended to use less planful problem solving and less positive reappraisal than the control group. As some uses of coping skills by patients with eating disorders were lower than those of the control group, developing coping skills may be useful in treatment for eating disorders in Japan.

[The frequency of Streptococcus pneumoniae strains and sensitivity surveillance for several antibiotics in Gifu Prefecture].

The frequency and the antibacterial sensitivity of Streptococcus pneumoniae strains isolated from 6 key hospitals (in 5 areas) and 1 otorhinolaryngology clinic in Gifu Prefecture from February to March, 1999, were investigated with several antibiotics. A total of 128 strains of Streptococcus pneumoniae were isolated throughout the study: 47 strains (36.7%) of penicillin-susceptible S. pneumoniae (PSSP), 51 strains (39.8%) of penicillin-intermediate S. pneumoniae (PISP), and 30 strains (23.4%) of penicillin-resistant S. pneumoniae (PRSP); the resistant bacteria being relatively prominent. In these hospitals, PSSP was isolated by 38.8% in all the key hospitals and by 30% in the otolaryngology clinic with almost no discernible difference. PISP was isolated by 63.3%, higher in the otolaryngology clinic and PRSP by 28.6%, higher in the key hospitals conversely. The MIC90s in PISP and PRSP were determined with the antibiotics. In result, only cefditoren (CDTR) showed favorable antibacterial activities with the MIC90 of 0.78 microgram/ml among penicillins or oral cephems. The MIC90s of carbapenems such as imipenem (IPM), meropenem (MEPM), and panipenem (PAPM) were less than 0.39 microgram/ml; particularly, PAPM showed the highest antibacterial activities. Among new quinolones such as tosufloxacin (TFLX), levofloxacin (LVFX), sparfloxacin (SPFX), and ciprofloxacin (CPFX), TFLX showed the highest antibacterial activities with the MIC90 of 0.39 microgram/ml. Other agents showed very low antibacterial activities as the MIC90s were 25 micrograms/ml in minocycline (MINO) and more than 100 micrograms/ml in clarithromycin (CAM) and clindamycin (CLDM).

Comparison of gastric lesions in dogs and cats with and without gastric spiral organisms.

OBJECTIVES: To determine prevalence of gastric spiral organisms (GSO) in dogs and cats that were clinically normal or had primary gastrointestinal disease and to compare histologic lesions of the stomach in dogs and cats with and without GSO. ANIMALS: 21 dogs and 10 cats that were clinically normal and 56 dogs and 33 cats with gastrointestinal disease. DESIGN: Case-control study. RESULTS: Unevenness of the gastric mucosal surface was detected, using endoscopic techniques in 20 and 25% of clinically normal and abnormal dogs, respectively. On histologic examination, GSO were located on the mucosal surface within or beneath the mucus, in gastric pits, and within glandular lumina in 86 and 90% of clinically normal dogs and cats, respectively, and in 61 and 64% of clinically abnormal dogs and cats, respectively. Prevalence of GSO infection in dogs and cats that were clinically abnormal was not higher than in those that were clinically normal. Infection was detected in stomachs of > 60% of dogs and cats 1 year old or less. Helicobacter pylori was not isolated from any specimen; however, specimens in which GSO were found had positive results on a urease test. CLINICAL IMPLICATIONS: Prevalence of GSO infection was high in clinically normal and abnormal dogs and cats, some of which were young. This should be considered during assessment of clinically normal animals with GSO as they can be a potential reservoir for infection in human beings.

Hemodynamic and endocrine responsiveness to mental arithmetic task and mirror drawing test in patients with essential hypertension.

To evaluate the reactivity to psychological stress in patients with essential hypertension we investigated hemodynamic and endocrinologic changes during a mental arithmetic task (MAT) and a mirror drawing test (MDT) in 10 hypertensive subjects. Hemodynamic changes were assessed continuously using an ambulatory radionuclide cardiac detector. There were significant increases in systolic blood pressure (deltaSBP: +37.8 +/- 11.1 and +41.0 +/- 9.4 mm Hg during MAT and MDT, respectively, P < .01) and diastolic blood pressure (deltaDBP: +17.5 +/- 3.1 and +21.2 +/- 3.9 mm Hg, P < .01) and in heart rate (deltaHR: +17.1 +/- 5.3 and +12.5 +/- 2.9 beats/min, P < .01) during both tasks in association with an increase in cardiac output (CO). The plasma levels of norepinephrine and epinephrine increased during both the MAT (deltaNE: +0.074 +/- 0.022 ng/mL, P < .01; deltaEP: +0.068 +/- 0.025 ng/mL, P < .01) and the MDT (deltaNE: +0.067 +/- 0.034 ng/mL, P < .01; deltaEP: +0.030 +/- 0.011 ng/mL, .05 < P < .1). Although the deltaNE was similar in response to the MAT and MDT, the deltaEP during the MDT tended to be less than half the deltaEP during the MAT (.05 < P < .10). The deltaEP was positively correlated with the deltaDBP and the deltaCO during both tasks and with the deltaSBP and the deltaHR during the MAT. These findings suggest that MAT- and MDT-induced increases in BP were attributable mainly to an increase in CO, possibly as the result of stimulation of the sympathoadrenomedullary system. However, the sympathoadrenomedullary system appeared to be more closely associated with the hemodynamic responses during the MAT than during the MDT.

EEG-driven photic stimulation effect on plasma cortisol and beta-endorphin.

The effect of EEG-driven photic stimulation on stress-related endocrine function was studied. Subjects were 16 healthy males divided into a photic stimulation group (n = 8) and a control group (n = 8). Electrodermal and emotional lability measures were assessed by nonspecific skin conductance response and the Maudsley Personality Inventory, respectively. Plasma cortisol and beta-endorphin concentrations were measured both before and after EEG-driven photic stimulation as well as the resting condition. Subjects with electrodermal, emotional, or both lability showed comparable decreases of plasma beta-endorphin on photic stimulation as did the stable subjects. Under resting control conditions, however, they showed significant increases of beta-endorphin compared to both stable subjects as well as the photic stimulation condition. In addition, labile subjects showed significant alpha enhancement on photic stimulation compared to stable subjects and to the resting control condition. The data suggest that increases of plasma beta-endorphin in labile control subjects may denote a stress response to the conditions of these experiments, and that any decrease by EEG-driven photic stimulation may indicate a reduction of responsiveness to an acute stress.

Comparison of gastric and duodenal lesions in dogs and cats with and without lymphocytic-plasmacytic enteritis.

OBJECTIVE--To compare histologic lesions in the stomach and duodenum of dogs and cats with and without lymphocytic-plasmacytic enteritis (LPE). DESIGN--Case-control study. ANIMALS--20 clinically normal dogs, 40 dogs with LPE, 10 clinically normal cats, and 20 cats with LPE. RESULTS--Unevenness of the mucosal surface was detected in the stomach of 4 of the 20 (20%) clinically normal dogs and 10 of the 40 (25%) dogs with LPE. Mucosal friability was detected in the duodenum of 16 (40%) of the dogs with LPE and 10 of the 20 (50%) cats with LPE. Histologically, clinically normal dogs and dogs with LPE had various degrees of fibrosis in the gastric lamina propria. All of the clinically normal cats and the cats with LPE had slight gastric fibrosis. Clinically normal cats had infiltrates of inflammatory cells similar to those seen in the clinically normal dogs. Significantly more plasma cells and lymphocytes were seen in the duodenal lamina propria of dogs and cats with LPE than in the duodenal lamina propria of clinically normal animals. CLINICAL IMPLICATIONS--LPE should be diagnosed by counting the number of inflammatory cells in the duodenal lamina propria and then comparing that number with the number seen in clinically normal animals.

Epidemiological data on anorexia nervosa in Japan.

An epidemiological survey on anorexia nervosa was performed in Japanese hospitals in 1985 and 1992 using a questionnaire. The reported number of patients with anorexia nervosa was 2391 from 732 institutions. From these data, the total number of anorexia nervosa patients treated in 1985 in Japanese hospitals was estimated to be about 3500-4500. In 1992, the reported number of patients with AN was 2247. The total number of AN patients treated in 1992 was estimated to be about 4500-4600, which is a little higher than that in 1985 (3500-4500). The prevalence was 3.6-4.5 per 100000 among the general population, 6.3-9.7 per 10(5) among the female population, and 25.2-30.7 per 10(5) among the 13-29 year-old female population.

Treatment of a depressive disorder patient with EEG-driven photic stimulation.

This study examined the effects of electroencephalographic- (EEG-) driven photic stimulation on a case of depressive disorder, as measured by a psychometric test of mood states, EEG parameters, and several autonomic indices. The EEG-driven photic stimulation enhances the alpha rhythm of brain waves using photic signals, the brightness of which is modulated by a subject's own alpha rhythm. The patient was a 37-year-old businessman, who was treated for depression with medication during the 13 months prior to his first visit to our hospital. He underwent two sets of inpatient treatment sessions, comprising first 16 and then 18 treatment sessions. The treatments brought about the following changes: an improvement in general mood state, alpha rhythm increase, cardiac parasympathetic suppression, and increased skin conductance level. In addition, significant correlations between alpha rhythm increase and cardiac parasympathetic suppression or cardiac sympathetic predominance were observed with each inpatient treatment. Significant correlations between alpha rhythm increase, cardiac parasympathetic suppression, or cardiac sympathetic predominance and the improvement of general mood state were also observed. Thus, from these observations, it was concluded that the alpha enhancement induced by EEG-driven photic stimulation produced an improvement in the patient's depressive symptomatology connected with cardiac parasympathetic suppression and sympathetic predominance.

Relationship of parental bonding to child abuse and dissociation in eating disorders in Japan.

Parental bonding patterns were studied in 52 female Japanese eating disorder outpatients with and without histories of sexual or physical abuse and with dissociation. Instruments included the Parental Bonding Instrument (PBI), the Dissociative Experiences Scale (DES) and the Dissociative Disorders Interview Schedule (DDIS). Those with physical abuse history, but not sexual abuse history, had significantly different parental bonding scores and higher DES scores compared with subjects without physical abuse. DES scores and PBI scores were not correlated. Although the PBI was useful in discriminating between those with and those without abuse histories, it did not detect differences in degree of dissociation. Lack of association of sexual abuse to PBI and DES scores may have been due to mild abuse.

Dissociation and child abuse histories in an eating disorder cohort in Japan.

Dissociation and childhood abuse were studied in female eating disorder outpatients in Japan. A self-report version of the Dissociative Disorders Interview Schedule (DDIS), which includes data on physical and sexual abuse, and the Dissociative Experience Scale (DES) were used. Nine of 41 subjects who completed the DDIS reported symptoms suggesting DSM-III-R multiple personality, and 6 of the 39 subjects who completed the DES scored over 30 (reflecting a high likelihood of posttraumatic stress or multiple personality). Subjects' sexual abuse history rates were considerably greater then those in the Japanese general population. Though physical abuse history was associated with high dissociation, no difference was seen between the high and low dissociators in sexual abuse histories.
