A new antidepressant, amoxapine, which is a dibenzoxazepine deprivative, was compared with amitriptyline in a randomised double-blind trial. Forty-eight patients were included and 41 completed a 4-week treatment. Most of the patients were maintained on 150 mg daily. Assessments were made by the Hamilton Psychiatric Rating Scale for Depression (HAM-D), Nurses' Observation Scale for Inpatient Evaluation (NOSIE), Clinical Global Impression (CGI) scale and Patient's Self-Evaluation. The total HAM-D score was considerably reduced in the majority of the patients. Amitriptyline was the most effective with regard to symptoms included in the factor Sleep Disturbances and-secondary maybe-towards some items included in the factor Somatization. For the remaining items,including the items of the factors Anxiety/Depression and Apathy, the last score was lower in the amoxapine group than in those treated with amitriptyline. Among the unipolar cases the amoxapine treated patients were more satisfied with regard to efficacy (P = 6.3%). The frequency of side effects such as tremor and dizziness was considerably lower in the amoxapine group. In total, the side effects lasted longer in the amitriptyline group. We conclude that amoxapine seems to be an effective antidepressant with a low frequency of side effects.

In this report, we described a case of acute lymphoblastic leukemia with leukoencephalopathy that responded to oxygenation under hyperbaric pressure (OHP) therapy. The patient was 6 year-old female who was diagnosed as acute lymphoblastic leukemia (ALL) one year and 9 months earlier. After the first relapse of the central nervous system (CNS) leukemia, intrathecal administration of methotrexate (MTX) and skull irradiation induced CNS remission. The patient was readmitted because of second CNS relapse. After the third administration of weekly intrathecal MTX injection, apathy and finger tremor were observed. Her conscious disturbance continued for two weeks and magnetic resonance imaging (MRI) revealed abnormal findings in the white matter of her brain. Subsequently OHP therapy was commenced, and the conscious disturbance was improved gradually. One month later, neuro-disturbance resolved completely and the findings of MRI were improved. We could not find any case of leukoencephalopathy which was treated with OHP in the literature. But our case suggested that OHP therapy is valuable in patient with leukoencephalopathy in the early stage.

Depressive mood is frequently associated with Parkinson's syndrome, but it may also occur as a precursor of this disease. As regards the subtypes of Parkinson's disease, the frequency of depressive states is significantly higher in the type dominated by akinesia and rigidity than in the type dominated by tremor. On the basis of biochemical changes, certain aspects of the depression can be successfully treated by substitution therapy: L-dopa medication may increase the reduced dopamine values in the striatum, thereby improving drive. Substitution with L-tryptophan raises the lowered serotonin values in the reticular formation, which may influence sleep disturbances. The changes of basic mood, however, which are characteristic of depression, such as cheerlessness and apathy, are the dopamine of antidepressive medication; only these drugs can re-establish the biochemical balance to a large extent.

Apathy, mood depression and extrapyramidal signs consisting of akinesia, amimia, gait apraxia, slight rigidity and tremor were induced in 10 patients by long-term treatment with flunarizine for trivial complaints. These symptoms suggest a mild antidopaminergic activity of flunarizine. Long-term administration of flunarizine should be avoided particularly in the elderly and in patients with extrapyramidal disorders.

Of 70 autopsied patients with the acquired immune deficiency syndrome (AIDS), 46 suffered progressive dementia that was frequently accompanied by motor and behavioral dysfunction. Impaired memory and concentration with psychomotor slowing represented the most common early presentation of this disorder, but in nearly one half of the patients either motor or behavioral changes predominated. Early motor deficits commonly included ataxia, leg weakness, tremor, and loss of fine-motor coordination, while behavioral disturbances were manifested most commonly as apathy or withdrawal, but occasionally as a frank organic psychosis. The course of the disease was steadily progressive in most patients, and at times was punctuated by an abrupt acceleration. However, in 20% of patients a more protracted indolent course was observed. In the most advanced stage of this disease, patients exhibited a stereotyped picture of severe dementia, mutism, incontinence, paraplegia, and in some cases, myoclonus. The high incidence and unique clinical presentation of this AIDS dementia complex is consistent with the emerging concept that this complication is due to direct brain infection by the retrovirus that causes AIDS.

Study of ACTH responsiveness to oral metyrapone and insulin hypoglycemia in children with repetitive nervous system manifestations (convulsions, coma, mental confusion apathy, tremor) has led to diagnosis of isolated ACTH deficiency in nine children within a three year period. Hypoglycemia was ascertained in five children; in four cases no hypoglycemia was proved, possibly because of promptly disappearance or because of other mechanisms accounting for clinical symptoms (occurrence of intracellular overhydratation associated with corticol deficiency is considered). The incidence of isolated ACTH deficiency in children is possibly undervalued. Reappraisal of isolated ACTH deficiency in childhood as to be considered in idiopathic spontaneous hypoglycemia and perhaps in some paroxysmal neurologic and/or digestive manifestations without proved hypoglycemia and so far poorly defined or held for epileptic fits. In order to disclose further additional tropic hormone deficiencies, and to differentiate permanent from transient impairment of ACTH responsiveness which often seems to be related to emotional deprivation syndrome, more protracted follow up studies are needed.

Thermal stress was induced experimentally in the hybrid pigs LW X L, weighing 45 to 52 kg. The trials were repeated in boxes heated to the temperature of 43 to 47 degrees C. The pigs were examined for the values of tremor, pH, partial pressure of carbon dioxide (pCO2), base excess (BE), buffer base (BB), standard and actual bicarbonate (SB and AB), total carbon dioxide (tCO2) and partial oxygen pressure in blood (pO2). Thermal stress caused marked tachycardia, polypnoea, higher body temperature, increased blood pH, reduction of partial carbon dioxide pressure. Respiratory alkalosis was accompanied by cardiovascular weakness, general excitation followed by apathy, cyanosis and dyspnoea.

Serum samples from three patients with Balkan endemic nephropathy (BEN) were inoculated intraperitoneally to guinea pigs. After a very long incubation period (58-273 days) the animals developed an experimental disease characterized by apathy, tremor, convulsions and a fatal outcome. The disease could be serially propagated, the same clinical symptoms being recorded at each of the three passages performed. The morphological features of the experimental disease included glomerular and tubular lesions and the presence of interstitial fibrous and lymphoplasmocytic reactions. Different hypotheses on the etiology of BEN are discussed.

Magnesium deficiency may complicate many diseases. The causes include the following: inadequate intake during starvation or increased requirement during early childhood, pregnancy, or lactation; excessive losses of magnesium as a result of malabsorption from the gastrointestinal tract or from the kidneys during use of diuretics; and to a combination of the two, as in alcoholism. Most often the etiological factors have been operative for a month or more. Acute hypomagnesemia can occur without previous Mg deficiency after epinephrine, cold stress and stress of serious injury or extensive surgery. The clinical manifestations depend on the age of the patient and may begin insidiously or with dramatic suddenness, or there may be no overt symptoms or signs. The manifestations can be divided into the following categories: totally non-specific symptoms and signs ascribable to the primary disease; neuromuscular hyperactivity including tremor, myoclonic jerks, convulsions, Chvostek sign, Trousseau sign (rarely), spontaneous carpopedal spasm (rarely), ataxia, nystagmus and dysphagia; psychiatric disturbances from apathy and coma to some of all facets of delirium; cardiac arrhythmias including ventricular fibrillation and sudden death; hypocalcemia which is responsive only to Mg therapy; and hypokalemia which is not easily nor completely corrected without Mg therapy. The diversity of etiologies and the multiplicity of manifestations result in confusion and controversy. The documentation of normal renal function is absolutely necessary for maximum doses. The order of magnitude of dose is 1.0 meq Mg/kg on day 1, and 0.3 to 0.5 mEq/kg per day for 3 to 5 days. In emergencies such as convulsions or ventricular arrhythmias, a bolus injection of 1.0 gm (8.1 meq) of MgSO4 is indicated. Therapy of Mg deficiency in the presence of renal insufficiency requires smaller doses and frequent monitoring. Complete repletion occurs slowly.

The aim of the present work was to study the behavioral effects elicited in adult cats by the selective D1 agonist, SKF 38393, and the D2 agonist, LY 171555, comparing their effects with those evoked by apomorphine. In 10 adult cats, 0.5, 1.0, 4.0, and 8.0 mg/kg IP of SKF 38393 were administered at random. A dose-response effect was observed related to alertness, indifference, and locomotion. The overall effect of SKF 38393 was inhibitory. To the same 10 animals, LY 171555 in doses of 0.25, 0.5, and 1.0 mg/kg were injected IP. This drug had an excitatory and more complex effect than what was observed with the D1 agonist. Increases in locomotion, in alertness, indifference, fear, olfaction, pupillary dilation, hallucination, limb flicking, and head shaking were recorded. Apomorphine given to the same cats, in a dose equimolar to 1.0 mg/kg of LY 171555, elicited behaviors that resembled those elicited by the latter drug, but of a lesser intensity and duration. The interval between the different treatments was approximately 2 months. These results show clearly that the D2 receptor is the main dopaminergic receptor involved in the mechanism of production of most of the behavioral effects produced by some of the dopaminergic agonist drugs like apomorphine.
