[Facial myokomias in brain stem tumors].

Four cases of brain-stem tumor were described, in which myokymias were electromyographically derived from the region of several cerebral nerves. An attempt is made to interpret the effects of twitching by reference to the electromyogram. Myokymias are a positive indication of organic brain stem damage. The use subtle techniques of electromyographic examination shows that this muscular hyperkinesis is not so infrequent a symptom as is generally believed.

[The diabetic polyneuropathy. I. Relation between impaired function in peripheral nerves and clinical findings].

789 patients with diabetes mellitus were studied by clinical and electroneurographical investigation. Motor and sensory conduction velocities of the median nerve and motor conduction velocity of the tibial nerve were determined. 86.1% of the patients suffered from juvenile diabetes, and 13.9% from maturity onset diabetes. Average duration of the disease was 9.5 years, average age of the patients was 26.7 years. Clinical signs of polyneuropathy were found in 19.1%. In 40.9% of the patients at least one of 3 conduction velocities was found to be delayed. Patients with clinical signs of polyneuropathy exhibited delayed nerve conduction velocities and delayed distal latencies. Diagnosis of polyneuropathy almost with certainty is possible by determining the three nerve conduction velocities and the three corresponding distal latencies. 22% of patients without clinical signs of polyneuropathy exhibited electroneurographical signs of impaired peripheral nerve function. Heredity, body weight, lipid metabolism, actual metabolic balance, and treatment were found to be without any significant influence on nerve conduction velocity.

[The diabetic polyneuropathy. II. Polyneuropathy, angiopathy and nerve conduction velocity].

789 patients with diabetes mellitus were studied by clinical and electroneurographical examination. Motor conduction velocity of the median and the tibial nerve and sensory conduction of the median nerve were determined. 81.1% of the patients we suffering from diabetes which began in childhood or adolescence, 13.9% were suffering from maturity onset diabetes. Average duration of the disease was 9.5 years, average age was 26.7 years. Clinical signs of polyneuropathy were found in 19.1%. Typical findings were pain and paraesthesia, lack or abolition of triceps surae reflexes, impaired pallaesthesia on lower extremities. 48.3% of 151 patients with clinical signs of polyneuropathy were suffering from combined angiopathy, 32.5% from microangiopathy, 7.9% from macroangiopathy. Severity of complicating retinopathy and macroangio,athy were found to be correlated with polyneuropathy. 58.2% of 323 diabetics with at least one delayed nerve conduction velocity exhibited signs of angiopathy. In nearly 30% of children and adolescents after comparatively short duration of the disease at least one conduction velocity was delayed. In diabetic children and adolescents metabolic disturbances are assumed to cause peripheral nerve dysfunction.

[Treatment of epilepsy with clonazepam (Antelepsin)].

Clonazepam (Antelepsin) was tested on 179 patients in 8 institutions during a period of 180 days. 169 patients had been unsuccessfully treated with the usual standard medication and were additionally given Antelepsin. Typical absences and attacks of the West and Lennox syndromes yielded best to treatment with the drug, with favorable effects also being produced in cases of partial or focal epilepsy. The most important side-effect was tiredness, other collateral effects being balance disorders, sensations of dizziness, and musuclar weakness. The frequency of side-effects decreased in the course of therapy. In the electroencephalogram there was observed a significant increase in beta waves and a significant decrease in 3 Hz spike and wave complexes.

[Diabetic polyneuropathy. 3. Electroneurographic findings in diabetics and their relationships to age and duration of diabetes].

Nerve conduction velocities were determined in patients with diabetes mellitus: motor conduction of the median nerve in 778 patients, sensory conduction of the median nerve in 680 patients and motor conduction of the tibial nerve in 745 patients. In 40.9% out of 778 patients at least one of the three nerve conduction velocities were found within pathological ranges. 30.4% of 227 patients below 19 years of age in whom the duration of the disease did not exceed four years exhibited at least one delayed nerve conduction velocity. Clinical signs of polyneuropathy in children and in adolescents below 19 years of age are rare (0.6%). In contrast delayed nerve conduction velocities were found in 29.4%. Metabolic disturbance of peripheral nerve function is assumed to be responsible in these patients, for angiopathy in children and adolescents is very rare too.

[Quantitative analysis of the electromyogram using triggered correlation].

A study has been made to determine the usefulness of triggered correlation as a method of automatic quantitative analysis of graphic representations of the somatic electric currents associated with muscular action. Although an electromyogram is neither a normally distributed nor a stationary random process, the method has been found to be suitable for clinical electromyography. The method is easy to use, with measuring values that may be used for diagnostic purposes being obtained within a few seconds. In the case of normal subjects and patients with neuromuscular diseases, parameters of triggered correlograms are compared with those of visuamanually analyzed or digitally averaged potentials of individual motor units.

[The EEG in subacute sclerosing panencephalitis (SSPE)].

This article gives an overview of electroencephalographic results obtained in the case of subacute sclerosing panencephalitis. Severe disturbances of background activity have been observed in all patients. Repetitive complexes usually occur transitorily, so that they cannot always be detected in individual cases. Repetitive complexes must be regarded as being typical of the disease, and consideration must be given in this connection to their particular characteristics (repetition frequency, constancy of form, relations to disorders characterized by myoclonus) and the clinical picture.

[Changes depend on age in electromyogram -- studies about parameter of motor unit action potentials in normal subjects of different age (author's transl)].

In normal subjects of different age groups electromyographically several muscles were examined. The motor unit action potentials were registered and parameters of those were evaluated manually and digitally. For all examined muscles was found an increase in the duration of potentials with the age. The increase was greatest in the younger and older age groups. An interpretation of these findings is given.

[Parameters of digitally averaged potentials of individual motor units].

Of sixty normal subjects of different age six different muscles each were examined electromyographically. The activity pattern was recorded for moderate voluntary innervation and superposed digitally. The parameters of digitally averaged summation action potentials were compared with those of manually assessed potentials. The two methods gave identical results: The duration of potentials was between 5 and 10 ms. It increased in the younger and older age groups and showed only slight changes in middle-aged persons. Only minor differences were found between the muscles of one age group, an exception being the orbicularis oris muscle. The results obtained are compared with values reported in the literature.
