Persons who contacted the Anorexia/Bulimia Association of Norway for information and stated that they had an eating disorder were asked to participate in this questionnaire study. The answers from the 32 women who fulfilled the DSM-III-R criteria for bulimia nervosa are presented. Usually the women's eating problems had started in the teens after a period of voluntary dieting. The mean duration of bulimia nervosa was six years. 31% had a history of anorexia nervosa. At the time of the study almost all had normal body weight, but nevertheless felt overweight. 78% practised self-induced vomiting, 22% used laxatives and 16% used diuretics to reduce weight. Depressive and anxiety symptoms were common in connection with the overeating episodes, but also more generally, which interfered with everyday life. Somatic symptoms (abdominal pain, diarrhoea, constipation, dyspepsia, headache, dry mouth and eyes, parotid gland swelling, muscular symptoms, fatigue, and oligomenorrhoea) were also common.

To determine whether there was a metabolic basis for recent reports that bulimic patients had low energy requirements for weight maintenance, energy expenditure measurements were made in 15 women with bulimia nervosa during abstinence from bingeing and vomiting. Resting metabolic rate, adjusted for differences in lean body mass, was significantly lower in bulimics (mean +/- SE, 4201 +/- 126 kJ/d) than healthy volunteers (4694 +/- 172 kJ/d). Bulimic patients had a blunted increase in oxygen consumption in response to low and moderate levels of exercise (421 +/- 16 and 689 +/- 17 mL/min) compared with values for healthy volunteers (491 +/- 28 and 795 +/- 26 mL/min). Plasma triiodothyronine (1.1 +/- 0.07 vs 1.4 +/- 0.08 nmol/L) levels, plasma norepinephrine levels in supine (0.58 +/- 0.04 vs 1.06 +/-0.17 nmol/L) and standing (1.34 +/- 0.15 vs 2.46 +/- 0.30 nmol/L) subjects, and the increase in norepinephrine levels during orthostatic challenge (0.76 +/- 0.15 vs 1.40 +/- 0.25 nmol/L) all were significantly less in bulimics than volunteers. These results are consistent with previous reports of decreased energy requirements for weight maintenance and decreased plasma levels of metabolism-related hormones in patients with bulimia. However, the effects of reduced energy intake in metabolic studies of patients with bulimia need to be further investigated.

Because binge eating in obese individuals has been postulated to be a reaction to dietary restriction, we examined the recorded food intake of 17 obese women with and 16 obese women without binge eating disorder (BED) during 1-week periods before and 3 months after a very low calorie diet program in order to determine the effects of dietary restriction on binge eating frequency and severity. Before weight loss, rather than reporting severe caloric restriction, women with BED reported greater average energy intake than nonbinge eaters on both a total (2707 vs. 1869 k cal/day, p < .01) and weight-adjusted (25.1 vs. 18.1 kcal/kg, p < .01) basis, with both higher intake on nonbinge days and an increased frequency of binge days. After weight loss, there was no significant difference in energy intake, on either a total or weight-adjusted basis, between subjects with and without BED. Although average daily energy intake fell for both groups after weight loss, only subjects with BED reported significantly decreased energy intake when adjusted for change in body weight. This resulted from decreased intake on nonbinge days and a decreased frequency of binge days. Before weight loss, subjects with BED reported an average energy intake equivalent to 94% of their predicted energy expenditure. Whereas subjects without BED reported intake only 64% of predicted (p = .002). After weight loss, there was no significant difference between subjects with and without BED in the percentage of predicted energy expenditure reported as intake (64% vs. 58%). Restraint was similar in both groups before weight loss, but those with BED reported greater hunger and disinhibition. After weight loss treatment, restraint increased significantly, whereas disinhibition and hunger remained elevated in subjects with BED. Disinhibition, rather than restraint, appears to be a major contributor to the disordered eating of these individuals. Unlike normal-weight women with bulimia nervosa, dietary restriction does not appear to worsen symptoms of binge eating in obese women with BED. Over the short term, subjects with BED may respond to a standard weight loss treatment program with improvements in binge eating behaviors.

Nineteen bulimic women and 22 age-matched controls were randomly assigned to receive 25 g of glucose or a placebo injection under double-blind conditions. Blood samples of glucose, insulin, and glucagon, and psychometric assessments of mood and food cravings were obtained 10 min before, and 0, 5, 10, 20, 30, 45, and 60 min after injection. Blood levels of the large neutral amino acids (LNAAs) tryptophan, tyrosine, leucine, valine, phenylalanine, and leucine were determined at 10 min before and 60 min after the injection. Bulimic subjects were found to report more symptoms of distressed mood throughout the entire monitoring period than controls. Five minutes following glucose ingestion the self-reports of depression, fatigue, anxiety, and bewilderment rose to a level among the bulimic subjects that was above that at baseline, and was higher than that of bulimia nervosa (BN) subjects receiving placebo. No comparable change in mood was observed among controls. Blood glucose levels were correlated with mood in the bulimic group, but not in controls. In addition, the glucose injection induced a heightened urge to binge in the bulimic group (compared to placebo at 10 and 60 min), whereas reducing food cravings (for sweets) in the controls (at 5 min). When collapsed across time and injection condition, the blood glucose level of bulimics was lower than that of controls. There were no differences in insulin response between the groups. The bulimic group was found to have lower baseline levels of blood tryptophan, whereas no differences in the tryptophan/LNAA ratio were observed either at baseline or following glucose.(ABSTRACT TRUNCATED AT 250 WORDS)

The eating disorder bulimia nervosa is characterized by alternating periods of strict dieting and overeating. Patients also report mood fluctuations, frequent eating related thoughts, fear of loss of control over eating, impairment of cognitive abilities such as concentration, and somatic complaints. The present study attempted to clarify to what extent these symptoms are consequences of the dieting behavior. Nine healthy young women, classified as unrestrained eaters, were set on a intermittent dieting schedule over 4 weeks. Four days each week (Tue, Wed, Thu, Fri) they had to reduce their intake below 600 kcal/day, the other 3 days they could eat without restrictions. Psychological variables were assessed by means of a standardized diary. Biological indices of starvation were also measured repeatedly. There was no substantial weight loss after the 4 weeks, although subjects had significantly increased levels of beta-hydroxybutyric acid during the dieting periods, and decreased levels of t3 after 2 weeks. The reported tendency to overeat and the actual calorie intake during the days of unlimited access to food showed a significant increase over the 4-week period. Eating-related thoughts, feelings of hunger, and fear of loss of control were significantly more frequent during periods of dieting, compared to days of normal eating. Subjects also reported worse mood, heightened irritability, difficulties concentrating, and increased fatigue. These results suggest that a substantial part of symptoms of bulimic patients might be associated with the frequent periods of an extremely restrained eating behavior.

In order to clarify the differences in mood states between anorexia and bulimia nervosa, the Profile of Mood States (POMS) with tension-anxiety, depression, anger-hostility, vigour, fatigue and confusion scales was administered to 32 female patients with anorexia nervosa (age range 14 to 32 years, mean age 20 years), 49 female patients with bulimia nervosa (age range 15 to 33 years, mean age 23 years) and 410 'normal' female subjects (age range 14 to 35 years, mean age 23 years). The scores on the depression, fatigue and confusion scales for both anorexia and bulimia nervosa and those on the tension-anxiety and anger-hostility scales for bulimia nervosa were significantly higher than those for the control subjects. The score on the fatigue scale for bulimia nervosa was significantly higher than that for anorexia nervosa. Moreover, the result of the multiple logistic regression analysis including all of the POMS scales indicated that the fatigue scale significantly discriminated between the two disorders. Fatigue mood appears to be a principal indicator for differentiating between the two disorders.

A 29-year-old woman presented to the emergency department with exhaustion, fatigue, and abdominal pain. She reported having received a diagnosis of bulimia nervosa 10 years before. On examination, she had a marked pallor and was severely malnourished. Laboratory analysis revealed a dramatically low hemoglobin level of 1.7 g/dL (ref: 11.5-15.8 g/dL). Serum iron was quantified as 1.4 micromol/L (ref: 7-26 micromol/L), ferritin as 5 ng/mL (ref: 10-120 ng/mL), and the level of serum transferrin as 212 mg/dL (ref: 200-360 mg/dL). A duodenal biopsy revealed villous atrophy in the mucosal layer indicative for celiac disease. This diagnosis was confirmed by serum levels of endomysial antibodies, tissue transglutaminase antibody, and antigliadin antibodies. The newly diagnosed gluten-sensitive enteropathy is likely to be in part responsible for the severe symptoms reported. The extent of hemoglobin decline in combination with an astonishing lack of critical symptoms seen in this patient is a rarity. We conclude that anorectic patients with severe anemia and malnutrition should be evaluated for the presence of additional somatic conditions.

Bullying is a well-known adversity among school-age children. According to data, approximately 10 percent of US children and adolescents are the victims of frequent bullying by peers. In the aftermath of being bullied, victims may develop a variety of psychological as well as somatic symptoms, some of which may persist into adulthood. Psychological symptoms may include social difficulties, internalizing symptoms, anxiety, depression, suicidal ideation, and eating disorders (i.e., anorexia or bulimia nervosa). Somatic symptoms may include poor appetite, headaches, sleep disturbances, abdominal pain, and fatigue. In both mental health and primary care settings, being aware of these types of psychological and somatic symptoms in vulnerable children and adolescents may expedite the identification and eradication of these abusive experiences.This ongoing column is dedicated to the challenging clinical interface between psychiatry and primary care-two fields that are inexorably linked.

The current study examined the features of women with bulimic-type eating disorders (n = 24) attending primary care in two smaller urban regions of the USA. The assessment included measures of eating disorder psychopathology, medical comorbidity, impairment in role functioning, potential barriers to treatment and actual use of health services. Eating disorders, primarily variants of bulimia nervosa and binge eating disorder not meeting formal diagnostic criteria, were associated with marked impairment in psychosocial functioning. Although two-thirds of participants recognized a problem with their eating, less than 40% had ever sought treatment from a health professional for an eating or weight problem and only one in ten had sought such treatment from a mental health specialist. Only one-third had ever been asked about problems with eating by a primary care practitioner or other health professional. However, more than 80% had sought treatment from a health professional for symptoms of anxiety or depression. Most reported some degree of discomfort in discussing eating problems with others, and half reported that they would not be truthful about such problems if asked. Having an eating disorder was associated with several chronic medical conditions, including joint pain, gastrointestinal problems and fatigue. Although the small sample size limits any firm conclusions, the findings suggest that the health burden of bulimic-type eating disorders is substantial but remains largely hidden. Efforts may be needed to improve the eating disorders "mental health literacy" of both patients and primary care practitioners in order to facilitate early, appropriate intervention.

Psychostimulants play a central role in the management of ADHD. Here we review the evidence pertaining to the use of methylphenidate, dexamphetamine and related amphetamine salts, the prodrug lisdexamfetamine and modafinil for the management of comorbid ADHD and non-ADHD indications. There is a growing consensus that stimulant medications are helpful at improving the emotional dysregulation and lability, and oppositional and conduct symptoms that are often associated with ADHD. There is some evidence that psychostimulants may improve outcomes in those with treatment resistant depression, reduce negative symptoms and improve cognitive performance in schizophrenia, and that methylphenidate may reduce binge eating in those with bulimia nervosa. In general medicine, whilst the evidence is at times contradictory, psychostimulants have been shown in some studies to be effective treatments for chronic fatigue and narcolepsy, and to improve outcomes post stroke, post head injury, in dementia and various cancers. It seems likely that these effects often result from a combination of, reduction in fatigue, improvements in concentration and cognitive functioning and a lifting of mood which may be a direct or indirect consequence of the medication. Further studies seem warranted and these should focus on efficacy, effectiveness and long term safety. This article is part of the Special Issue entitled 'CNS Stimulants'.
