An analysis of seven sporadic cases of Legionnaires' disease confirmed clinical features recorded during epidemics and identified aspects of the illness either unreported or not emphasized. Four patients had central nervous system abnormalities. Mental status changes included somnolence, obtundation, delirium, disorientation, and confusion. Three patients experienced visual hallucinations, and one patient without pneumonia had a grand mal seizure with residual memory deficit. Two patients had disseminated intravascular coagulation with thrombocytopenia, elevated split fibrin products, and prolonged partial thromboplastin and prothrombin times. Four patients had severe hypoxia; one patient had an exudative pleuritis. One patient whose treatment included erythromycin had radiologic improvement of his pneumonia despite deteriorating ventilatory function that led to death. The concept of Legionnaires' disease as a severe, diagnostically perplexing pneumonic illness is valid but too narrow. The emerging spectrum is that of a multisystem disease that, besides the lungs, often involves the central nervous system and can be accompanied by disseminated intravascular coagulation.

Benzonal was given to 52 epileptics. In 50 cases the duration of treatment ranged from 3 months to 7 years (mean 18 months) in doses of 100-500 mg daily, in 2 cases it had to be withdrawn after a short-term treatment because of intolerance. In all cases the drug was given together with other anticonvulsants: hydantoin, derivatives, mysodin, Tegretol, pheneturid or Ospolot in place of previously administered phenobarbital. It was found that benzonal reduced significantly the frequency of partial simple seizures (in 6 out of 20 cases) and grand mal seizures (in 24 out of 34 cases), while its action on the partial complex seizures was much weaker (improvement in only 7 out of 20 cases). The drug was usually well tolerated, side effects of greater intensity developed in 2 cases only, transient somnolence was observed in another 6 cases. In EEG records a slight favourable effect was exerted on pathological background activity with absent effect in focal changes and increase of seizure activity. The authors believe that in view of its favourable clinical action and good tolerance the drug may be widely used in properly selected cases of epilepsy.

Benign myoclonic epilepsy in infancy (BME) is characterized by the occurrence of brief myoclonic attacks in normal infants aged 4 months to 3 years. There is no prior personal history, although in some patients 1 or 2 isolated febrile convulsions may occur prior to the onset of myoclonias. A family history of epilepsy or febrile convulsions is present in 30% of cases. Myoclonic attacks are short and mild, they involve mainly the head and upper limbs. The psychomotor development continues normally after the onset of seizures. The EEG shows a normal background activity and generalized spike-wave or polyspike-wave discharges associated with the myoclonias. These abnormalities are activated by drowsiness and during the first stages of sleep. A clinical and EEG photosensitivity is present in one-third of the patients. Myoclonias can be easily controlled by valproate monotherapy. Rare grand mal seizures can occur during adolescence, after withdrawal of drug treatment. The psychomotor evolution is good if treatment is started early. When myoclonias begin during the first year of life, the diagnoses of cryptogenic infantile spasms and of non-epileptic benign infantile myoclonus must be eliminated. In cases with a later onset, the following diagnoses can usually be easily discarded: cryptogenic Lennox-Gastaut syndrome, myoclonic-astatic epilepsy and unclassified epilepsies with the association of myoclonias and other types of seizures.

We report a patient with encephalitis who showed anterograde and retrograde amnesia with MRI abnormalities localized in the bilateral amygdala (AM) and hippocampus (HIPP). A 25-year-old man suddenly experienced a generalized tonic-clonic seizure (GTCS). He was admitted because of increasing lethargy with two further GTCSs during the following 6 days. The patient had high fever, and neurological examination revealed somnolence, disorientation, amnesia, and nuchal stiffness. MRI revealed bilateral symmetrical abnormalities localized in the AM and HIPP, which showed low intensity on T1-weighted images and high intensity on T2-weighted images. Cerebrospinal fluid examination showed a mildly elevated cell count. We suspected herpes simplex virus type I encephalitis and began treatment with acyclovir. After the patient regained a clear consciousness, his antero- and retrograde amnesia continued for several months. The MRI abnormality became less distinct with the improvement of amnesia. We consider that the MRI abnormality was indicative of inflammation and edema, and that the lesion in the AM and HIPP had induced the amnesia.

The principal action of the sedative-hypnotic drugs, of whom the barbiturates are the most widely known and utilized, is to produce drowsiness and promote sleep. At one time these were also the only drugs available to calm seriously anxious or disturbed people. Unfortunately, in addition to their clinical applications these drugs manifest a very high abuse potential. Experienced drug abusers report feelings of well-being and euphoria while under the influence of these drugs. Self-administration experiments conducted in animals have shown that the barbiturates are potent reinforcing agents. In controlled studies in humans, former drug abusers express a preference for barbiturates over benzodiazepines and will "work" to receive barbiturates. Long term consumption of the sedative-hypnotics, particularly barbiturates, leads to dependence characterized by a severe, potentially life-threatening abstinence syndrome following the abrupt withdrawal of the drug. Withdrawal manifestations include delirium and grand mal seizures. Because of the high abuse potential of these drugs, their manufacture and distribution has been greatly curtailed, and for most clinical applications they have been largely replaced by drugs, e.g., the benzodiazepines, which appear to have much less abuse liability.

Two cases of hypnotic sequelae occurring in a research context (with a non-clinical college population) are reported. Case 1 was a male who experienced retroactive amnesia following hypnosis: He was unable to recall familiar telephone numbers later that day. This was not a continuation of an earlier confusion or drowsiness (as is often found) since he indicated he was wide awake following hypnosis. Two parallels exist with previous reports: unpleasant childhood experiences with chemical anesthesia and a conflict involving a wish to experience hypnosis but a reluctance to relinquish control. Case 2 was a female who, while in hypnosis, experienced an apparent epileptic seizure that had characteristics of both petit mal and grand mal seizures. Although having a history of epilepsy, she had not had a seizure in 7 years. We suspect that the seizure was psychogenic and may have been triggered by wording used in the hypnotic scale or other similarities. Possible mechanisms are discussed and preventative recommendations are made.

A 15-year-old girl was admitted to our clinic on July 16, 1985 with the epilepsy which had been resistant to various anticonvulsant therapies. At the age of 10 years automatism seizure, characterized by purposeless movement of arms and head of which the patient was unaware, began to occur and became as frequent as two to three times each day. From the age of 13 years, there were also grand mal seizures several times a year in spite of medical treatment. She had normal delivery and no history of febrile convulsion. There was no family history of epilepsy or mental disease. When examined on admission, she had normal personality and intelligence. There was no neurological abnormality. She complained of sleepiness and hirsutiness. Fit of automatism occurred two to three times a day during admission, though the blood levels of anticonvulsant drugs such as phenobarbital, phenytoin and carbamazepine reached to therapeutic concentration. EEG examination including infratemporal lead recording showed right temporal spike focus. But all the neuroradiological studies such as skull X-rays, CT, cerebral angiography and magnetic resonance imaging failed to show abnormal finding. Right temporal lobectomy was carried out under general anesthesia on Aug 22, 1985, and anterior two-thirds of the middle and the inferior temporal gyri were resected deeply to anterior hippocampus. To the naked eye, no abnormal finding was noted during the operation. In the surgical specimen, macroscopically nothing abnormal was found. Microscopically, serial sections of the lobe revealed clusters of oligodendroglial cells in cortical to subcortical region of the medial basal part of the temporal lobe.(ABSTRACT TRUNCATED AT 250 WORDS)

For 18 previously untreated patients with absence, myoclonic, or grand mal seizures--or combinations--results of clinical and electroencephalographical monitoring are reported. Sodium valproate was given once daily in the evening. Monitoring included repeated 24-48 h EEG recordings and drug blood level measurements. Results indicated the evening monodose to be an adequate therapeutic schedule for a considerable number of patients. Apart from the aspect of simplification, a further important aim is to individually minimize the drug dose. An average of 15.6 mg/kg sodium valproate (range, 10.0-25.5 mg/kg) per day was administered. In some cases the EEG discharge activity continued to be lowered even after the drug blood level had reached steady state. With medication, frequency and total duration of paroxysms were significantly lowered (by more than 90%) in over 80% of the patients, whereas the mean duration of paroxysmal activity did not change uniformly. Before treatment, short paroxysms (1-5 s) were seen together with longer ones in 11 patients. During treatment either all paroxysms disappeared or, in cases of remaining activity, most discharges were short and not accompanied by seizure manifestations. Blood level profiles over 24 h showed maximal values between midnight and 2 a.m. The minimal values (about half of the maximum) were found between 10 p.m. and midnight. The 8 a.m. value was 70-80% of the maximum. Only three patients complained of slight side effects (temporary drowsiness, loss of hair). Because of the simplified handling, the relatively low dose per day, and the few side effects, it seems possible that for primary generalized epilepsies once daily evening administration of sodium valproate is appropriate without diminishing the antiepileptic effect.

1. Intravenous clonazepam was investigated in an open trial conducted in 24 patients suffering from status epilepticus. 2. The administration of 1-2 mg clonazepam resulted in the complete control of 7/7 Petit Mal, 7/14 Grand Mal and 2/3 partial complex cases. 3. The mean time to obtain clinical control of seizures after injection was 1.75 min. In all successfully treated cases normalization or improvement of the post-ictal EEG tracing was observed. 4. Vital signs measured before and immediately after clonazepam injections showed no clinically significant changes in blood pressure, heart rate or respiration. Side effects consisted exclusively of transient mild to moderate drowsiness in 40% of patients. 5. These results indicate that intravenous clonazepam is rapidly effective and safe in the treatment of Petit Mal status and in certain cases of Grand Mal and partial complex status epilepticus. This agent therefore represents a useful alternative to diazepam in the treatment of status epilepticus.

A placebo-controlled crossover design, with each treatment period lasting 6 weeks, was used to investigate effects of dronabinol in 15 patients with a diagnosis of probable Alzhemer's disease who were refusing food. Eleven patients completed both study periods; one patient who died of a heart attack 2 weeks before the end of the study was also included in the analysis. The study was terminated in 3 patients: one developed a grand mal seizure and 2 developed serious intercurrent infections. Body weight of study subjects increased more during the dronabinol treatment than during the placebo periods. Dronabinol treatment decreased severity of disturbed behavior and this effect persisted during the placebo period in patients who received dronabinol first. Adverse reactions observed more commonly during the dronabinol treatment than during placebo periods included euphoria, somnolence and tiredness, but did not require discontinuation of therapy. These results indicate that dronabinol is a promising novel therapeutic agent which may be useful not only for treatment of anorexia but also to improve disturbed behavior in patients with Alzheimer's disease.
