A transient but considerable rise in serum creatine phosphokinase (CPK) levels occurred in six boys aged between 8 and 11 years and suffering from phenothiazine-induced dystonia. In one boy (Case 4), after the CPK level had returned to normal after withdrawal of the drug, its reintroduction orally at lower dosage caused a slight increase in the level of CPK in the absence of any recurrence of the dystonia.

The authors study 50 case records of hiatus hernia operated according to the modified technic of Nissen or Toupet. There was no anatomical relapse, but they observed in five cases an imperfect functional result. In three cases, this imperfect result with dysphagia and esophageal dilatation, is transient and is due to restoration of the sphincter. In two other cases, the dysphagia persisted for years after the operation. The latter cases were in young subjects with digestive dystonia. From these cases, the authors distinguish hernias due to ageing and those due to deterioration of the meso-esophagus, easily curable surgically, and hernias in young subjects due to a neuro-hormonal disturbance where surgical reconstruction of the sphincter does not produce the expected functional cure.

The results of tests with physical load on a bicycle ergometer and treadmill in 50 patients with ischemic heart disease were compared. The control group was formed of 20 patients with neurocirculatory dystonia. Agreement between the results of both tests was encountered in 90% of patients with ischemic heart disease. The authors conclude that the tests do not differ essentially in the main indices (rate of cardiac contractions, index of cardiac activity at the peak of the load, time of uninterrupted work until the criteria of load cessation). It is suggested that tests on the treadmill and those on the bicycle ergometer in patients with ischemic heart disease are equivalent.

A 5-month-old infant had an unusual combination of clinical signs and symptoms. These consisted of irritability, dystonia, lack of head control, grimacing, opisthotonos, choreoathetoid movements, delayed development, and severe metabolic acidosis. Metabolic investigation by gas-liquid chromatography/mass spectrometry detected urinary organic acids. This confirmed the diagnosis of L-glutaric aciduria. The concentration of L-glutaric acid in the patient's plasma was 2.5 mg/dl (normal range, 0 to 0.1 mg/dl), and in the patient's urine was 4.6 mg/mg of creatinine (normal range, 0 to 0.05 mg/mg of creatinine), but the concentration was not elevated in the plasma and urine of the infant's parents nor of two other family members. No glutaryl-CoA dehydrogenase activity was found in leukocytes taken from the patient. Three of the four family members, including the parents, demonstrated 38%, 42%, and 42% activity, respectively, compared with the activity of normal controls. These findings are consistent with an autosomal recessive disorder involving the metabolism of glutaryl-CoA to crotonyl-Co-a. Dietary restriction was instituted on two separate occasions. First, a low protein diet of 1.6 gm/kg of body weight per day was given, then a low lysine intake of 50 mg/kg/day. These dietary manipulations caused a decrease in the plasma and urine concentrations of L-glutaric acid and beta-hydroxyglutaric acid. However, no effect on the clinical manifestations of the disease was noted.

Carbamazepine is an anticonvulsant most effective in treating complex partial and generalized tonic-clonic seizures. We have cared for three children in whom four episodes of dystonia proceeding to opisthotonus occurred in association with carbamazepine use. The patients, a 4-year-old with microcephaly and severe retardation, a 1-year-old with cerebral dysgenesis, and a 5-year-old with spastic quadriplegia and mild retardation, all had seizures unresponsive to multiple anticonvulsant combinations. In all three patients carbamazepine was introduced and gradually increased to a maximum dosage of 25 mg/kg of body weight per day. Dystonic symptoms began two to three weeks after introduction of therapy and subsided within three weeks after discontinuation. In one child, a second course of carbamazepine resulted in a return of the dystonia. The currently available clinical and neuropharmacologic data suggest that carbamazepine may be an antagonist of dopamine and that this property is responsible for the production of dystonia.

Thirteen patients with acute dystonia and extrapyramidal symptoms as a result of drug intoxication are reported. In a number of instances, the symptoms were due to more than one drug being given to the patient, among which were phenothiazine derivatives, non-phenothiazine tranquilizers and metoclopramide. Diazepam (Valium) given intravenously caused the patients to fall asleep immediately and to wake within an hour, free from all symptoms. It is felt that in patients with drug-induced extrapyramidal symptoms, diazepam should be considered as the possible drug of choice.

Four women with Parkinson's disease undergoing prolonged levodopa therapy had daily episodes of dystonic posturing, affecting one lower extremity, several years after initiation of treatment. The dystonia occurred only in the early morning, on awakening and before the first dose of levodopa, when the patients were in the akinetic-rigid state with no dyskinesias. It further interfered with gait, slowly subsided within one to two hours, and did not recur until next morning. This abnormal involuntary posture was unaffected by manipulations of daily levodopa dosage and schedule, completely disappeared after withdrawal of drug therapy, and recurred following its readministration. Additional adverse reactions including dyskinesias, "on-off" phenomena, and declining efficacy of levodopa were present in all patients. Early-morning dystonia may represent another late side effect secondary to long-term levodopa administration in parkinsonism.

After a clarifying outline on the most recent anatomo-physiopathologic acquisitions about muscular tone and spasticity, the Author presents the results of a prolonged administration (three months) which was daily controlled, in an Institute for dyskinetic subjects. At the dose of 1 mg/kg/die during the first week, 2 mg/kg/die during the second week and 3 mg/kg/die during the third and the following ones (total posology pro die divided into 3 post-prandium administrations), Dantrolene was administered to 16 subjects of both sexes, whose average age was 13, who presented marked spasticity sometimes accompanied by dystonia. An evaluation was given on these parameters: 1) spasticity estimated in three degrees according to Morosini, 2) passive articular movement (wideness and easiness of maximum excursion), 3) capability of voluntary decontraction, 4) motoricity of relation (motorial difficulty) and 5) dystonic component if present. As a global results, out of 16 cases, nine improved (56%) and seven (44%) remained unaltered. Since the drug resulted to be inefficacious in all cases with dystonia, the global improvement recorded among "pure spastics" rised to 66% of cases. Neither intolerances nor negative secundary effects were noticed.

Tiapride, a substituted benzamide derivative closely related to metoclopramide, reduced levodopa-induced peak dose involuntary movements in 16 patients with idiopathic Parkinson's disease. However, an unacceptable increase in disability from Parkinsonism with aggravation of end-of-dose akinesia led to its cessation in 14 patients. Tiapride had no effect on levodopa-induced early morning of "off-period" segmental dystonia. These results fail to support the notion that levodopa-induced dyskinesias are caused by overstimulation of a separate group of dopamine receptors.

Intramuscular neutrolysis with phenol has been used for 10 years in the management of spasticity in children. Best results depend on fastidious technique and realistic use of the procedure. Sedation or anesthesia was used in all cases -- 5% phenol in water was used for all procedures. The main indications were spasticity which interfered with function, either actual or potential, or with care. Where uninhibited vestibular or tonic neck reflexes affect muscle tone, or there is dystonia or athetosis, the procedure is less effective than where spasticity alone is present. Duration of relief of spasticity ranged from 1 month to more than 2 years. About one half of the lower extremity muscle treated required tenotomy later. Generally training was required after the procedure to obtain improved function. A representative sample of muscles treated, repeat procedures, and later surgery is discussed. The procedure is recommended for use in the management of spasticity in children as a way of improving function and/or care.
