Twelve children with severe chronic behavior disorders who benefited from treated with lithium carbonate over an extended period of time (6 to 33 months) are described. Behavioral features common to all included hostility, aggressiveness, and distractibility. Nine had cyclic mood swings, with periods of withdrawal and periods of manic excitement; six of these had neurovegetative disorders. These nine children may have manic-depressive disease of childhood. Three children had no cyclic symptoms, though their hostile and aggressive behavior was similar to that of the cyclic group; they responded similarly to lithium. Family histories were strongly positive for manic-depressive disease, depression, and alcoholism. A double-blind placebo-controlled crossover study in four patients supported the specific behavioral effect of lithium.

A large number of reports have been devoted to the physiologic and toxic effects of methyl chloride, many of which are based on case histories involving occupational exposure. The detrimental actions of methyl chloride on the central and peripheral nervous systems are well established effects. It is a moderately severe narcotic and potentially severe nerve poison. Chronic intoxication is associated with damage to the central nervous system (CNS), kidneys, liver, bone marrow, cardiovascular system, respiratory system, and intestinal tract. The signs and symptoms range from the more severe medical dysfunctions such as cardiac irregularities, respiratory paralysis, nerve degeneration, and severe convulsions to the more subtle clinical observations such as CNS depression, nervousness and emotional instability, insomnia and anorexia, ataxia, blurred vision, light-headedness, nausea, dizziness, narcosis, and disorientation. The behavioral correlates of these and other neurotoxic effects of methyl chloride suggest that a gradual behavioral degradation occurs. Pharmacodynamic studies have shown the compound to be rapidly absorbed by the blood with most authors attributing the toxicity to an enzyme-catalyzed methylation reaction in the body. Despite the fact that several investigators have attempted to correlate such biological responses of methyl chloride with its toxicity, the present knowledge of the problem still lacks a detailed mechanism of action. Until such mechanisms are verified, adequate methods to assess subclinical neurological and behavioral changes must be effectively developed.

Case histories of four elderly patients with central nervous system signs of digitalis toxicity were reviewed. Evidence of toxicity included lethargy, depression which was not present previously, confusion, restlessness, emotional instability, hyperventilation, and vertigo. Vomiting developed four days after the onset of the mental changes. No cardiac arrhythmias were observed. Digoxin serum levels ranged between 4.2 and 7.0 ng/ml. Serum potassium values were within normal limits. Three of the four patients recovered with a return of their mental status to the pretoxic state. The fourth case was fatal. At autopsy long-standing myocardial ischemia was the only significant finding.

Bipolar affective disorder (manic-depressive disease) is a mental disturbance characterized by phases of both depression and mania. Mania is essential to the diagnosis and is characterized by elevated mood, flight of ideas, and increased psychomotor activity. Current psychiatric literature not only shows that this disease is familial but has also demonstrated, through linkage studies, that an X-linked dominant mode of inheritance adequately explains the strong prevalence of bipolar affective disorder in some families. The family discussed here shows many of the known clinical aspects of bipolar affective disorder. It serves as an example consistent with the X-linked dominant mode of inheritance. Knowledge of the genetic background of this disease aids the family physician by helping to identify members of the family likely to have acquired this condition. The family physician can then look for future problems in them and in their offspring, leading to earlier diagnosis and more effective management. Thus, a member of a bipolar family with supposed unipolar illness (depression only) might be better served with the prophylactic use of lithium carbonate because of his likelihood of possessing a bipolar genotype. The prophylactic use of this drug has been shown effective in reducing the frequency, duration, and intensity of both manic and depressive mood swings.

Comparison of a series of twenty-four wrist-cutters with a control group of self-poisoners showed a number of significant differences. The wrist-cutters were younger and their acts were regarded as being of low lethality; they are no more likely to have made previous suicide attempts; they complain less often of depression, and more frequently of 'emptiness' and tension as primary complaints. Sudden, unpredictable mood swings are common and there is a greater tendency for their physicians to diagnose personality disorders, often in pejorative terms. They frequently have substantial medical interests and paramedical occupations. A high proportion complain of dysorectic symptoms (anorexia or overeating or combinations of both), use drugs and/or alcohol in excess; show sexual disturbance and distress, and also promiscuity. They more frequently have a negative reaction to menarche and menstruation; have come from broken homes and have experienced parental deprivation. A proportion of the group exhibit difficulty in verbal communication, and absconding from hospital was more common in the group of cutters. Painless cutting after a period of depersonalization, followed by relaxation and repersonalization after bleeding, was the typical pattern.

Acute mood changes occur with various forms of physical activity. Increased levels of endogenous opioids (endorphins) in response to exercise may mediate activity-induced shifts in mood state. Thirteen female and six male aerobics class participants aged 20-46 years received the opiate receptor antagonist naltrexone and a placebo in randomized, double-blind crossover fashion on two separate occasions at the same 75-min high-intensity aerobics class. Mood states were assessed before and after each class, which were spaced 5 days apart, using the Profile of Mood States questionnaire (POMS), a mood adjective checklist, and a Visual Analogue Scale (VAS) which measured mood in relation to several emotional extremes. Mood changes over the course of each aerobics class were compared in the naltrexone and placebo groups. For men and women, significant differences between conditions were observed in overall mood by both the POMS (P less than 0.005) and VAS (P less than 0.02). There were significant differences between conditions for most subscales of each mood instrument (P less than 0.05); with the placebo, mood states became calmer, more relaxed and pleasant, tending away from depression, anger and confusion. Positive mood shifts did not occur when subjects were preloaded with naltrexone, suggesting that activity-generated mood changes are mediated through endorphinergic mechanisms.

Neurofibromatosis is one of the most frequent autosomal-dominant hereditary disorders. Neoplastic, dysplastic and dysraphic lesions characterize the disease from the viewpoint of a neurologist. Depression, suicide, emotional instability, learning disability and behavior disorder are important aspects for the neuropsychiatric evaluation. Treatment of the patients will be facilitated by following the diagnostic criteria and by an interdisciplinary approach to diagnosis. The gene-molecular differentiation of NF I and NF II provides a basis for a more profound understanding of the disease which allows for more than just the clinical description. Cloning of the gene of NF I will give the possibility of predictive diagnosis of NF I. At present an indirect prenatal diagnosis of the genetic disorder is possible by flanking markers of NF I.

The relative contribution of the instructions and the music to the effects of the Musical Mood Induction Procedure (MMIP) were investigated. Using an experimental procedure which minimised covert experimenter bias, subjects performed under both elation and depression mood inductions in one of four conditions: music present or absent by mood change instructions present or absent, using a crossover design. Results indicated that instructions were both necessary and sufficient to produce change on mood sensitive measures. Mood change effects were reduced by controlling for the effect of subjects who responded so as not to 'louse-up' the experiment. The MMIP seems to be much less musical than the name implies. Further research is needed to determine which aspects of the instructions contribute most to the changes on mood sensitive measures.

Adiposis dolorosa or Dercum's disease consists of a painful progressive localized state of obesity with four cardinal symptoms: a) painful circumscribed or diffuse fatty deposits, b) generalized obesity in women usually of menopausal age, c) asthenia, weakness and frequently tendency to fatigue and d) mental phenomena including emotional instability, depression, epilepsy, mental confusion and true dementia. Only a few cases in men have been described. The pain may be treated with intravenous administration of lignocaine or oral mexitil while no causal treatment is known. An illustrative case is reported.

This double-blind, randomized, crossover study compared the efficacy and safety of danazol (100 mg twice daily) with matching placebo in the treatment of severe premenstrual syndrome. Nineteen patients were randomly allocated to receive danazol for 3 months followed by placebo, and 18 to receive treatment in the reverse order. Assessments of overall condition showed improvement to be statistically significantly more likely with danazol than with placebo (P less than 0.001) after 3 months' treatment. Furthermore, daily visual analogue scale assessments demonstrated statistically significantly better premenstrual scores with danazol in comparison to placebo for breast discomfort, irritability, depression, anxiety, mood swings, crying, depressed libido and abdominal swelling. It is concluded that danazol provides effective and generally well tolerated treatment for severe premenstrual syndrome.
