Effect of chronic accumulation of aluminum on renal function, cortical renal oxidative stress and cortical renal organic anion transport in rats.

The aim of the present work was to study the nephrotoxicity of aluminum lactate administered for 3 months (0.57 mg/100 g bodyweight aluminum, i.p., three times per week) to male Wistar rats. Renal function was studied after 6 weeks of treatment (urine was obtained from rats in metabolic cages) and at the end of the treatment using clearance techniques. Another group of rats was used as kidneys donors at the end of treatment. The renal cortex was separated and homogenized to determine glutathione (GSH) level, glutathione S-transferase (GST) activity and lipid peroxidation (LPO) level. Renal cortex slices were also used to study the p-aminohippuric acid (PAH) accumulation during steady-state conditions and the kinetics of uptake process. Clearance results, at the end of the treatment, indicated that renal functions in treated-rats were not different from those measured in control rats, although the renal concentration parameters differ when they were measured in treated rats after 24 h of food and water deprivation. Balances of water and sodium were also modified at both 1.5 and 3 months of treatment. The activity of alkaline phosphatase (AP) relative to inulin excreted in urine was significantly impaired: controls 2.2+/-0.6 IUI/mg, Al-treated 5.1+/-0.5 IU/mg, P<0.05. These data indicated that proximal tubular cells were loosing apical brush border membranes. Data obtained in cortex homogenates indicated that both GSH and GST activity were significantly decreased, and a significant increase of LPO was noted simultaneously in Al-treated rats. Renal accumulation of PAH, estimated as slice-to-medium ratio, decreased significantly in the Al-treated rats: control rats 3.06+/-0.02 ( n=12), Al-treated rats 2.26+/-0.04 ( n=12), P<0.0001. The maximal rate of uptake was also diminished in treated rats, while the apparent affinity remained unchanged. All these results indicate that aluminum accumulation in renal tissue affects cellular metabolism, promotes oxidative stress and induces alterations in renal tubular PAH transport, together with an impairment in sodium and water balance only detected under conditions of water deprivation, without other evident changes in glomerular filtration rate or other global functions measured by clearance techniques at least at this time of chronic toxicity.

Intracoronary streptokinase thrombolytic recanalization and subsequent surgical bypass of remaining atherosclerotic stenosis in acute myocardial infarction: complementary combined approach effecting reduced infarct size, preventing reinfarction, and improving left ventricular function.

In 48 patients with acute myocardial infarction (AMI) the acutely thrombus-occluded coronary artery was successfully recanalized nonsurgically via catheter with intracoronary streptokinase (SK) infusion after a mean occlusion time of 3.1 +/- 1.6 hours. In all cases residual high-grade fixed atherosclerotic stenosis remained after percutaneous transluminal coronary recanalization (PTCR). Subsequent aortocoronary bypass surgery (ACBS) circumventing the stenotic coronary artery was performed during the acute stage of myocardial infarction (within 10 days of AMI onset) in 34 patients and electively (longer than 10 days after AMI onset) in 14 patients. No patient died from early PTCR or from ACBS intervention. There were two late post-ACBS arrhythmogenic deaths, two patients suffered nonfatal reinfarction post ACBS several months after hospital discharge, only two had occasional post-ACBS angina pectoris, and one patient had post-ACBS mild heart failure. The remaining 41 post-ACBS patients were completely asymptomatic throughout long-term follow-up evaluation. In the left ventricular (LV) segment supplied by the initially occluded coronary artery, which was recanalized early by means of SK therapy and subsequently grafted, wall motion improved significantly from the acute to the postoperative stage in patients who underwent early surgery (from 13.6% +/- 1.9% to 40.3% +/- 2.7%, p less than 0.001) and in the electively operated group (from 18.0% +/- 7.1% to 48.2% +/- 6.3%, p less than 0.001). Ischemic wall motion was improved irrespective of whether or not the bypass graft circumventing the residual stenosis of the infarct vessel remained patent. Wall motion of nonischemic segments remained essentially unchanged. In the patients who underwent surgery in the early stage, the closure rate of the bypass graft to the infarct-related vessel was 17%, and in the electively operated group no graft was found to be occluded. In conclusion, coronary artery recanalization, achieved by means of early SK-PTCR therapy with subsequent ACBS, can be performed safely in patients with AMI, and the result will be marked improvement in LV segmental wall motion and global function, diminished reinfarction rate, and reduced incidence of angina pectoris, all benefits that are consistently maintained during long-term evaluation.

Evaluation of left ventricular dysfunction using multiphasic reconstructions of coronary multi-slice computed tomography data in patients with chronic ischemic heart disease: validation against cine magnetic resonance imaging.

PURPOSE: Multi-slice computed tomography (MSCT) is an emerging technique for the angiographic assessment of coronary artery disease (CAD). The purpose of this work was to determine if multiphasic reconstructions of the same data used for the assessment of CAD could also be used for global functional evaluation of the left ventricle (LV). MATERIALS AND METHODS: Fifteen patients with chronic ischemic heart disease (CIHD) were imaged for CAD using a contrast-enhanced retrospective electrocardiographic-gated spiral technique on a MSCT scanner. The same data were reconstructed at both end-diastole and end-systole in order to measure left ventricular end-diastolic volume (LVEDV), end-systolic volume (LVESV), and ejection fraction (LVEF). The results were compared to values obtained using a cine true-fast imaging with steady-state precession technique on a magnetic resonance imaging (MRI) scanner. Interobserver variability in the measurement from MSCT images was also evaluated. RESULTS: For LVEF, there was substantial agreement between MSCT and MRI (intraclass correlation coefficient of 0.825); the intermodality reproducibility for LVEF (5%) was within an acceptable clinical range. However, mean values of LVEDV and LVESV with MSCT compared to cine MRI (LVEDV: 262.0 +/- 85.6 ml and 297.2 +/- 98.8 ml, LVESV: 196.2 +/- 75.6 ml and 218.6 +/- 90.99 ml, respectively) were significantly less for both volumes (p < 0.015). Intermodality variabilities for these measurements were high (15 and 13% for LVEDV and LVESV, respectively). Readers' mean measurements of LVESV from MSCT images were significantly different (p = 0.003) resulting in differences in calculation of LVEF (p < 0.024). Still, interobserver variabilities for all values were acceptable (6, 8, and 5% for LVEDV, LVESV, and LVEF, respectively). CONCLUSION: Although values for LVEDV and LVESV were less with MSCT than with MRI, LVEF values were in agreement. This suggests that combined imaging of CAD and the evaluation of global LV dysfunction due to CIHD is feasible with the same MSCT acquisition.

Influence of weight loss on myocardial performance index.

Obese patients may have a phase of asymptomatic left ventricular dysfunction. A combined myocardial performance index (MPI) has been demonstrated to be a useful index to estimate left ventricular function and to predict the prognosis of patients with heart failure. The objective of the study was to determine the influence of weight loss on MPI. A total of 18 obese patients (3 men, 15 women, mean age 49.6 +/- 5.5 years, body mass index [BMI] >30 kg/m(2)) were investigated in the study. All patients were treated with a multidisciplinary approach consisting of a hypocaloric diet and orlistat therapy (120 mg three times daily), and all of them underwent two-dimensional and Doppler echocardiographic examination two times before starting the study and after a period of weight loss. Using echo-Doppler methods, ejection fraction, peak velocities of early (E) and late (A) diastolic filling, the E/A ratio, deceleration time (DT), isovolumic contraction time (IVCT), isovolumic relaxation time, ejection time, and MPI were measured. The MPI was obtained by subtraction ejection time from the interval between cessation and onset of the mitral flow. All patients lost at least 10% of their initial body weight, with a mean decrease of 10.8 +/- 3.7 kg. This was associated with significant reductions in BMI with a mean decrease 4.5 +/- 1.4 kg/m(2). Compared with baseline, after weight loss the E/A ratio of 1.01 +/- 0.22 before treatment increased to 1.17 +/- 0.26 (P = 0.012), left ventricular mass index decreased from 88 +/- 23 to 82 +/- 19 g/m(2) (P = 0.028), IVCT from 71 +/- 20 to 53 +/- 30 ms (P = 0.004), DT from 233.65 +/- 38.14 to 196.72 +/- 47.73 s (P = 0.004), and MPI from 0.63 +/- 0.13 to 0.50 +/- 0.13 (P = 0.0001). Weight loss ameliorates MPI and seems to be a clinically relevant measurement of left ventricular global function, and may prove to be a valuable tool in assessing the risk of developing heart failure.

Pediatric Escola Paulista de Medicina Range of Motion Scale: a reduced joint count scale for general use in juvenile rheumatoid arthritis.

OBJECTIVE: Different instruments are available to measure functional status in juvenile rheumatoid arthritis (JRA); however, none is based on the evaluation of joint range of motion (ROM). We designed and evaluated a ROM scale to be used as a complementary instrument in daily practice with JRA as well as in trials. METHODS: The 10 joint movements of the Pediatric Escola Paulista de Medicina Range of Motion scale (Pediatric EPM-ROM) were derived from 25 initial movements. The selection was based on 2 criteria: (1) consensus among 3 pediatric rheumatologists, one physical therapist, and one occupational therapist; and (2) choice of movements that presented the highest scores in a pilot study involving patients with JRA. The score for each joint ranges from 0 (full movement) to 3 (severe limitation) and the cutoff degrees of motion are, in general, based on the lack of ability to perform some activities of daily living. The test-retest reliability was assessed by administering the scale twice by the same observer, 4 to 10 days apart, always in the morning. The interobserver reliability was evaluated on the same day by 2 independent observers. Cross sectional construct validity was also assessed by correlating the values of some clinical variables with the scores of the Pediatric EPM-ROM scale. RESULTS: The instrument was applied to 34 patients with JRA, 11 systemic, 11 polyarticular, and 12 pauciarticular. The mean EPM-ROM score was 0.57 (SD 0.54, min 0, max 2.05). The test-retest and interobserver correlation coefficients were 0.96 and 0.98, respectively. The Pearson correlation coefficients comparing scores of the Pediatric EPM-ROM scale and other variables were satisfactory: Childhood Health Assessment Questionnaire, r=0.55 (p<0.001); American College of Rheumatology global functional class, r=0.56 (p<0.001); and number of limited joints, r=0.65 (p<0.001). CONCLUSION: Our results provide evidence that the Pediatric EPM-ROM scale is a valid instrument to measure joint ROM in JRA.

Fast technetium 99m-labeled sestamibi gated single-photon emission computed tomography for evaluation of myocardial function.

BACKGROUND: This study assesses the feasibility of 99mTc-labeled sestamibi electrocardiographic gated single-photon emission computed tomography (SPECT) with a short acquisition time (6.7 minutes, "fast" gated SPECT) for the evaluation of stress myocardial perfusion and poststress myocardial function. Simultaneous assessment of stress perfusion and poststress function is possible with standard gated SPECT acquisition (19.3 minutes) of stress-injected sestamibi. Sestamibi gated SPECT can be used to evaluate regional wall motion (RWM), thickening, and left ventricular ejection fraction (LVEF); the feasibility of fast gated SPECT has not been evaluated previously. METHODS AND RESULTS: Fifty patients were studied who underwent treadmill exercise, sestamibi injection (25 to 30 mCi), and standard gated SPECT 15 minutes after exercise, immediately followed by fast gated SPECT. All patients underwent rest 201Tl SPECT before exercise testing. All studies were analyzed by semiquantitative visual scoring. Both standard and fast gated SPECT were read for stress perfusion and poststress wall motion and thickening, dividing the left ventricle into 20 segments, on a 5-point scale described previously. The measurement of LVEF used a previously described automatic algorithm. Average myocardial counts per pixel were 58 +/- 19 for standard gated SPECT and 13 +/- 4 for fast gated SPECT (p = 0.0001). Heart/lung ratio was 10.2 +/- 4.8 for regular gated SPECT and 10.3 +/- 5.7 for fast gated SPECT (difference not significant). Perfusion analysis showed exact agreement in 92% of the segments (kappa = 0.76; p < 0.01). Correlation between LVEFs measured from standard and fast gated SPECT was 0.94. Analysis of 998 segments (two segments were uninterpretable) showed exact agreement in 96% (kappa = 0.89; p < 0.001) for RWM and 94% (kappa = 0.83; p < 0.001) for thickening between standard and fast gated SPECT. In 225 segments with abnormal RWM and 189 segments with abnormal thickening by both standard and fast gated SPECT, exact agreements were 0.92 for RWM (kappa = 0.90; p < 0.001) and 0.87 for thickening (kappa = 0.80; p < 0.01). CONCLUSIONS: Our data demonstrate that fast sestamibi gated SPECT is feasible and yields results equivalent to those of standard sestamibi gated SPECT with respect to left ventricular regional and global function.

Neuropsychological correlates of hypertension.

Twenty newly diagnosed, untreated hypertensive men (diastolic blood pressure greater than 105 mm Hg) and 20 normotensive controls were given a neuropsychological battery, including tests of generalized, more global functions (eg, reaction time and full-scale IQ) and of specific functions (eg, language and visual-spatial abilities) sensitive to focal damage. Tests of specific abilities yielded no differences between the two groups. In contrast, tests of general neuropsychological functioning revealed a deficit among hypertensives, who were significantly slower on the reaction time test and had a shorter span for digits in forward order. Results suggest that arterial hypertension is associated with impairment of vigilance and attention span. Future research will determine whether this impairment is associated with the diffuse pathological changes seen in the brain of hypertensive subjects, or with a more "functional" change (eg, reduced cerebral blood flow).

Approach to the treatment of limb disorders with botulinum toxin A. Experience with 187 patients.

OBJECTIVE: To determine the dosing, response expectation, efficacy, and most rational strategy for using intramuscular injections of botulinum toxin A (BTX) for limb disorders. DESIGN: Open-label prospective analysis of outcome after BTX treatment in patients with limb disorders. PROCEDURE: Botulinum toxin A prepared from lyophilized botulinum toxin was injected into selected upper and lower limb muscles under electromyographic guidance. Booster injections were given every 10 to 14 days during the first month (if needed) until optimal effects were achieved. Clinical data and muscle strength testing were obtained before the first injections and repeated at each visit. Level of disability, global functional improvement, and relief of pain were evaluated 6 to 8 weeks after the first set of injections. Practical and meaningful BTX doses by muscle, limb, or condition according to specified levels of efficacy were developed. MAIN OUTCOME MEASURES: Botulinum toxin A efficacy was calculated as an arithmetic combination of changes in the 3 clinical ratings before and after administration of BTX. RESULTS: Botulinum toxin A injections were given to 187 patients with limb disorders during an 8-year period (136 with dystonia, 37 with parkinsonian, essential, and cerebellar tremors, and 14 with spasticity). Four overall outcomes from no effect to almost complete improvement in the use of the limb or relief of pain were found, and determined the strategy for follow-up injections. Average BTX efficacy for all patients was 65% and ranged from 83.5% for focal hand dystonia to 35.7% for parkinsonian tremor. Botulinum toxin A injections relieved pain, independent of motor function, in 82.7% of patients with painful muscle spasms. CONCLUSIONS: Botulinum toxin A was found to be a safe and useful treatment of various limb conditions. Botulinum toxin A was significantly more effective when only a few muscles needing low doses were injected, and tended to be more useful in dystonia and spasticity than tremor. Candidates for BTX injection could be categorized functionally into 3 groups independent of the underlying disorders. The only significant adverse effect of BTX injection in limbs was transient weakness in injected or neighboring muscles.

Open-label, multicenter, phase 3 extension study of the safety and efficacy of donepezil in patients with Alzheimer disease.

BACKGROUND: Donepezil hydrochloride is a selective acetylcholinesterase inhibitor approved for the symptomatic treatment of mild to moderately severe Alzheimer disease (AD). Controlled clinical trials of up to 24 weeks have demonstrated that donepezil treatment (5 and 10 mg/d) significantly improves cognition and global function. OBJECTIVE: To investigate the long-term benefits of donepezil treatment in patients with AD. DESIGN: Multicenter, open-label, 144-week extension of 2 US phase 3, double-blind, placebo-controlled clinical trials: a 15-week study (12 weeks of treatment followed by a 3-week placebo washout) and a 30-week study (24 weeks of treatment followed by a 6-week placebo washout). INTERVENTIONS: All patients (N = 763) initially received donepezil, 5 mg/d, for 6 weeks, after which an increase to 10 mg/d was encouraged. MEASURES: Primary efficacy measures were the Alzheimer's Disease Assessment Scale-cognitive subscale and the Clinical Dementia Rating-Sum of the Boxes. RESULTS: After the shorter 3-week placebo washout, donepezil-associated benefits remained above original baseline values for an additional 24 weeks of open-label treatment. Benefits on Alzheimer's Disease Assessment Scale-cognitive subscale scores for patients who received 10 mg/d in the double-blind study were evident compared with the other groups for 108 weeks of open-label treatment. In contrast, donepezil-associated benefits were lost after the 6-week placebo washout, and scores decreased below original baseline values for all patient groups. Although scores improved relative to the new open-label study baseline scores after drug use was restarted, patients remained below original baseline values. The most common adverse events were associated with the nervous and digestive systems and were generally mild and transient; 17% of patient discontinuations were associated with adverse events. CONCLUSIONS: Donepezil is an effective and safe drug for the long-term symptomatic treatment of mild to moderately severe AD for up to 144 weeks (2.8 years), and sustained treatment may confer some advantages.

A 24-week open-label extension study of memantine in moderate to severe Alzheimer disease.

BACKGROUND: This study is an extension of a 28-week, randomized, double-blind, placebo-controlled study of memantine in 252 patients with moderate to severe Alzheimer disease. OBJECTIVE: To evaluate long-term memantine treatment in moderate to severe Alzheimer disease. DESIGN, SETTING, AND PATIENTS: Open-label, 24-week extension trial. Raters remained blind to the patients' initial study treatment. Patients (n = 175) were enrolled from the previous double-blind study in an outpatient setting. INTERVENTION: Twenty mg of memantine was given daily. MAIN OUTCOME MEASURES: Efficacy assessments from the double-blind study were continued and safety parameters were monitored. RESULTS: Patients who switched to memantine treatment from their previous placebo therapy experienced a significant benefit in all main efficacy assessments (functional, global, and cognitive) relative to their mean rate of decline with placebo treatment during the double-blind period (P<.05). The completion rate for the extension phase of the study was high (78%) and the favorable adverse event profile for memantine therapy was similar to that seen in the double-blind study. CONCLUSION: These results extend previous findings that demonstrated the efficacy and safety of memantine in the treatment of patients with moderate to severe Alzheimer disease.

Progress in pharmacotherapy of borderline disorders. A double-blind study of amitriptyline, haloperidol, and placebo.

In symptomatic patients with borderline disorder, we conducted a double-blind, placebo-controlled trial of haloperidol and amitriptyline hydrochloride to test the differential efficacy of medication against the affective and schizotypal symptoms that characterize the disorder. Sixty-one patients, diagnosed by the Diagnostic Interview for Borderline of Gunderson et al, completed randomized trials of haloperidol (n = 21), amitriptyline (n = 20), and placebo (n = 20). Medications were given in dose ranges of 4 to 16 mg for haloperidol (mean, 7.24 mg) and 100 to 175 mg for amitriptyline hydrochloride (mean, 147.62 mg) for five-week periods, with weekly self-rated and observer-rated measures of mood, schizotypal symptoms, and global functioning. Haloperidol was superior to both amitriptyline and placebo on a composite measure of overall symptom severity, with no difference between amitriptyline and placebo. Haloperidol produced significant improvement on a broad spectrum of symptom patterns, including depression, anxiety, hostility, paranoid ideation, and psychoticism. In contrast, amitriptyline was minimally effective, with small gains limited to some areas of depressive content. The magnitude of change tended to be modest and was more apparent in self-rated than observer-rated measures.

An empirical study of defense mechanisms. I. Clinical interview and life vignette ratings.

The Defense Mechanism Rating Scales (DMRS) measure the use of defense mechanisms based on clinical interview or life vignette data. Using nonprofessional raters observing videotaped psychodynamic interviews of individuals with personality and affective disorders, the median intraclass interrater reliability (IR) of the defense scales was .36 but was .57 for group consensus ratings and .74 when related defenses were grouped into defense summary scales. When follow-up data on life vignettes were rated, the median interrater IR was .55 for those defenses occurring at least 5% of the time and .66 for the defense summary scales. In relation to follow-up data, so-called immature defenses (denial, projection, acting out, hypochondriasis, passive-aggression) were associated with higher levels of symptoms, poorer global functioning, and higher proportion of time impaired in psychosocial role functioning. Borderline defenses (splitting, projective identification) displayed a similar pattern. Among narcissistic and neurotic defenses, only devaluation was associated with poorer functioning, whereas intellectualization was associated with higher functioning. Finally, action and borderline defenses demonstrated significant correlations across methods and across time (video vs life vignettes), whereas obsessional, disavowal, and narcissistic defenses showed nonsignificant trends. Overall, these results support the model of a hierarchy of defenses.

Relationships over 1 year between lymphocyte subsets and psychosocial variables among adults with infection by human immunodeficiency virus.

To examine relationships between immune and psychosocial variables among adults infected with human immunodeficiency virus type 1, 221 subjects without acquired immunodeficiency syndrome were assessed for degree of depression, anxiety, psychiatric symptoms, social support, stressful life events, hardiness, hopelessness, bereavement, and intrusive and avoidant thoughts about acquired immunodeficiency syndrome. At entry, none of 22 psychosocial variables significantly correlated with lymphocyte subsets. Among subjects seen 6 and 12 months later, severity of physical symptoms was associated with greater emotional distress, but the CD4 cell count was predicted by neither clinical ratings of psychopathology and global functioning nor by standardized self-report measures of constructs used in psychoimmune research. We conclude that among our sample, physical symptoms contributed to emotional distress, but emotional distress did not contribute to the CD4 cell count, a marker of disease progression.

Impulsive aggression in personality disorder correlates with tritiated paroxetine binding in the platelet.

BACKGROUND: To examine the relationship between binding parameters of the platelet central serotonergic (5-HT) transporter and measures of aggression and impulsivity in adult human subjects. METHODS: Maximal number of platelet tritiated paroxetine binding sites (Bmax) and dissociation constant (Kd) values were measured in patients with personality disorder (n = 24) and healthy volunteers (n = 12). Measures of aggression and impulsivity included the total score and aggression subscale of the Life History of Aggression, the Motor Aggression factor and the assault subscale of the Buss-Durkee Hostility Inventory, and the total score and motor impulsivity subscale of the Barratt Impulsiveness Scale. RESULTS: The Bmax, but not Kd, values of platelet tritiated paroxetine binding was inversely correlated with the Life History of Aggression total score and aggression score and with the Buss-Durkee Hostility Inventory assault score in patients with personality disorder but not in healthy volunteer subjects. This relationship was independent of influences of factors related to depression, global function, or history of alcoholism or drug abuse. CONCLUSIONS: Reduced numbers of platelet 5-HT transporter sites may covary with life history of aggressive behavior in patients with personality disorder. This may represent another abnormality in 5-HT function in individuals with personality disorder and aggressive behavior.

Health status and health-related quality of life in long-term adult survivors of pediatric solid tumors.

We have examined the influence of selected factors (gender, marital status, socio-economic status, co-morbid conditions, access to medical care, age at diagnosis, intensity of therapy and time since diagnosis) on subsequent health status and health-related quality of life (HRQL) of long-term survivors of pediatric solid tumors. Two hundred and twenty individuals who had survived a pediatric solid tumor 15 years or longer completed telephone and written assessments of their current status. Health status was assessed using the Late Effects of Normal Tissues toxicity scale. HRQL was investigated using the Ferrans and Powers Quality of Life Index-Cancer (QLIC) and the EORTC Quality of Life Questionnaire C30 (QLQ-C30). Results indicated that health status and HRQL were better in survivors treated with low-intensity therapy. One hundred and thirty respondents (59.1%) reported at least 1 serious toxicity. Dyspnea and fatigue were commonly reported in survivors of Hodgkin's disease. Correlational analyses showed that predictors of health status included socio-economic status, marital status and the presence of co-morbid factors. Mean HRQL scores for the 4 domains of the Ferrans and Powers QLIC and the functional scales of the EORTC QLQ-C30 indicated that most of the survivors were experiencing moderately good to excellent HRQL. One-third of survivors reported that their history of cancer had an adverse impact on their current financial status. Prediction models constructed for 3 of the domains from the 2 HRQL instruments are presented (health and functioning, global HRQL and financial impact). Within these 3 models, consistent predictors of HRQL outcomes included health status, presence of dyspnea or pain, marital status and socio-economic status.

Correlates of severity in bulimia nervosa.

OBJECTIVE: We sought to clarify the correlates of severity in women with bulimia nervosa. METHOD: We studied 114 bulimic women at entry to a randomized clinical trial. We used eight definitions of severity that encompassed the DSM-III-R criteria set for bulimia nervosa (i.e., binging, purging, and body dissatisfaction in the current and worst lifetime time frames) and global functioning and symptomatology. We operationalized 28 possible correlates of severity that covered demographic, Axis I psychiatric, personality, family background, symptoms, and neuropsychological domains. We used regression techniques to investigate the associations between the correlates and severity indices. RESULTS: The regression models were all statistically significant and tended to account for a sizeable proportion of variance. In particular, earlier age of onset of bulimia and lower character scores (measured by the Temperament and Character Inventory) correlated with greater severity. Worse mean parental care (from the Parental Bonding Instrument), the absence of any lifetime anxiety disorder, and the presence of any lifetime mood disorder emerged as independent correlates in several models. CONCLUSIONS: As these were hypothesis-generating analyses, confirmation or refutation of these results awaits further study. In particular, age of onset of bulimia and personality traits related to character may be important modifiers of the severity of illness in bulimia nervosa.

Personality disorders in patients with eating disorders in Japan.

We assessed the prevalence of personality disorders (PD) using the Structured Clinical Interview for DSM-III-R Personality Disorders (SCID-II) in 36 patients with restricting anorexia nervosa, 30 patients with anorexia nervosa and bulimia nervosa, and 42 patients with bulimia nervosa. Of the 108 patients, 51% met the criteria for at least one PD. The patients with PD had more severe clinical features in terms of bulimic behaviors, concurrent depressive, anxious, and obsessive-compulsive symptoms, and psychopathology related to eating disorders compared to the patients without any PD. The patients with PD, especially borderline PD, also had more severe global functioning and greater numbers of suicidal attempts and hospital admissions. We compare these results with those reported in the Western world and discuss them cross-culturally.

Multi-impulsivity among bulimic patients in Japan.

OBJECTIVE: Studies in Western world patients suggest the possible existence of a subgroup of patients with bulimia nervosa (BN) who display multiple problems with impulsivity, such as suicidal attempts. We assessed impulsive behaviors among BN patients in Japan to discuss them crossculturally. METHOD: Impulsive behaviors in 64 BN patients were assessed and multi-impulsivity (MI) was defined according to the definition proposed by Fichter, Quadflieg, and Rief (Psychological Medicine, 24, 591-604,1994). RESULTS: Nineteen patients (30%) met the definition of MI. BN patients with MI had more severe clinical features, such as concurrent depressive and anxious symptoms, global functioning, and higher prevalence of borderline personality disorder than BN patients without MI. DISCUSSION: These results showed the similarities between BN patients with MI in Japan and those patients in the Western world in clinical and psychopathological characteristics and a life-time incidence of each impulsive behavior. These findings may suggest culturally free bases for linkage between BN and MI.
