Laxative abuse as a variant of bulimia.

Two groups of bulimic patients, one group characterized by a pattern of laxative abuse for purposes of weight control and the other group characterized by no history of laxative abuse, were compared on several behavioral variables associated with bulimia. Relative to the nonabusers, the laxative abusers were more likely to abuse diuretics; to use diet pills; to chew and spit out food; and to report a history of suicide attempts, self-injurious behavior, and prior inpatient treatment for depression.

Characteristics of 275 patients with bulimia.

The authors present data on 275 patients who met DSM-III criteria for bulimia. The mean age of the patients was 24.8 years, and the average duration of illness was approximately 7 years. These patients reported a variety of abnormal eating-related behaviors: binge eating (100%), self-induced vomiting (88.1%), laxative abuse (60.6%), diuretic abuse (33.1%), and chewing and spitting out food (64.5%). Over one-third reported a history of problems with alcohol or other drugs and most indicated substantial social impairment.

The interruption of bulimic behaviors. A review of three treatment programs.

This article reviews three programs for treating bulimic behaviors. Although the structures of these programs differ considerably, all are geared to an outpatient approach and stress patient education, behavioral self-monitoring, and healthy eating behaviors. The programs described demonstrate a heavy reliance on behavioral treatments including cognitive restructuring, emphasis on individual patient responsibility for progress in treatment, and an expectation for success by supportive therapists and by patients.

The dexamethasone suppression test in patients with bulimia.

In a series of 28 patients with bulimia who did not meet weight criteria for anorexia nervosa, 14 (50%) failed to suppress on the dexamethasone suppression test. Nonsuppression was not associated with degree of depression, body weight, or severity of abnormal eating-related behaviors. However, nonsuppression was associated with a higher rate of treatment for affective disorders in first-degree family members. The utility of the DST as a biologic marker for affective disorder in patients with bulimia is questioned, although a substantial level of depressive symptomatology was documented in patients with bulimia.

Treatment of canine blastomycosis with ketoconazole.

Four dogs with blastomycosis were treated with ketoconazole, and good results were obtained in 3 of the 4 cases. Dogs that responded to treatment had manifested a variety of the clinical forms of blastomycosis (osseous, pulmonary, lymphatic, and ocular), and all lesions in the dogs abated. There were no clinical signs or clinicopathologic evidence of adverse drug reaction or toxicosis. The results of the study suggested that ketoconazole is effective for the treatment of canine blastomycosis.

Electrolyte and other physiological abnormalities in patients with bulimia.

The frequencies of various forms of eating-related behaviour (such as vomiting and laxative abuse) are reported for a series of non-anorectic bulimia patients seen for evaluation in an eating disorders clinic. The results of serum electrolyte, glucose and other screening tests in these patients are presented. Electrolyte abnormalities were found in 82 of the 168 patients (48.8%) who were diagnosed as having either bulimia or atypical eating disorder. The most common abnormality was metabolic alkalosis (27.4%); hypochloremia (23.8%) and hypokalemia (13.7%) were also commonly seen. No significant blood sugar abnormalities were encountered. An elevated serum amylase level was found to be associated with frequent binge-eating and vomiting behaviour. The pathophysiology of electrolyte abnormalities in this patient group is briefly reviewed.

Patent ductus arteriosus with pulmonary hypertension in the dog.

The clinical, physiologic, and pathologic manifestations of patent ductus arteriosus (PDA) with pulmonary hypertension (right to left type PDA) were studied in 5 dogs. Cyanosis, hindlimb collapse, low-intensity heart murmurs, and splitting of the 2nd heart sound were prominent clinical findings. Secondary polycythemia was a feature in 3 dogs. Electrocardiography revealed marked frontal plane right axis deviation in all dogs. Radiographic findings in all dogs consisted of an enlarged right ventricle and main pulmonary artery segment, with a hypovascular pulmonary pattern. A wide descending aorta was evident in 4 dogs. Pulmonary arteriography revealed blunt, tortuous secondary and tertiary vessels. Blood flow through the PDA was from right to left in 4 dogs and bidirectional in 1. Necropsy of 1 dog revealed extensive pulmonary arterial disease characterized by fibromuscular intimal proliferation. Surgical correction was contraindicated, and medical therapy was not required in the 4 dogs retained by the owners as pets. Due to the persisting congenital heart defect and the real and potential sequelae, the prognosis is guarded.

Requesting previous psychiatric records. Do they come and are they worth obtaining?

This study examines the response rate to requests for previous records on adult psychiatric outpatients and the usefulness of the records received. Usable records were received in response to only 64.6 per cent of requests. In 40.9 per cent of the records examined, previous records revealed important information which had not been gathered at the time of outpatient evaluation. Possible reasons for the rate of response are discussed. The authors conclude that important information can be missed during the process of evaluation and that previous records may significantly add to the available data base on which to make diagnostic and treatment decisions. However, not infrequently requests for previous records are not answered.
