Data from 50 patients with juvenile myoclonic epilepsy (JME) were analyzed retrospectively to assess the response to drug therapy--long-term seizure control, relapse rates, and confounding factors in seizure recurrence. Valproate is the only available antiepileptic drug that has been shown to be effective in controlling the generalized seizure components of JME--myoclonic, tonic--clonic, and absence seizures--without significant side effects. Data were collected using the EpiMonitor software and represented case follow-up from 2 months to 9 years. Forty-three patients (86%) were seizure free for at least 1 year; 25 patients (50%) relapsed at some point during follow-up. Relapses were precipitated most frequently by fatigue, noncompliance, stress, sleep deprivation, and alcohol consumption. With accurate diagnosis and appropriate therapy, seizures in JME can be adequately controlled, although JME is a chronic disorder that may require lifelong therapy. To minimize relapse, patient management must also focus on patient lifestyle to eliminate or control lifestyle-associated precipitants of seizure relapse.

Alterations of consciousness with impaired perception and drive persisting over hours to days can be due to a nonconvulsive status epilepticus. This possibility has to be considered not only in patients with already known epilepsy, but also in those with a negative history for seizure disorders. The immediately recorded electroencephalogram (EEG) provides decisive clues. In the case of petit mal status most frequently appear tiredness, reduced vigilance and lack of drive. The EEG shows a generalized spike-wave activity. In status psychomotoricus, the clinical symptomatology varies from case to case. It can be characterized by anxiety, dreamy states or productive-psychotic states with agitation, automatisms and hallucinations. In the EEG a temporal or temporally-accentuated epileptic activity will be recorded. Transitional and mixed forms of petit mal status and status psychomotoricus can also be found. I.v. injections of benzodiazepines (clonazepam, diazepam) are an appropriate therapy for any type of nonconvulsive status epilepticus. Phenytoin is indicated in status psychomotoricus, but contra-indicated in the case of petit mal status.

rTNF was administered to 28 patients with advanced metastatic cancers by continuous intravenous infusion for 5 consecutive days every 2 weeks. The dose levels were 30, 40, 70, 110, 180 and 290 micrograms/M2/day. Groups of 3 patients were started at each successive dose level and then on subsequent courses treated with the next dose level through 4 escalations as tolerated. Tumor types were: colon cancer 14; adenocarcinoma of unknown primary, 2; renal cancer, 2; leiomyosarcoma, 2; lung cancer, 1; prostate cancer, 1; thymona, 1; bladder cancer; 1; parotid, 1; Kaposi's sarcoma 2; ovarian 1. Toxicities included fever and chills (usually within the first 8 hours of infusion), fatigue, headache, decreased performance status, hypotension and CNS. All patients experienced leukopenia and thrombocytopenia within 24 hours or less after start of infusion with return of baseline by 72 hours after rTNF was stopped. The fall in these counts averaged 50% and was not dose related. No major changes in liver or renal function, coagulation or blood lipids were seen. Major dose limiting toxicities were fatigue, confusion, thrombocytopenia, seizures, hypotension and decreased performance status. NK cell activity measured against K562 target cells was augmented from about 30% target cell lysis to about 70% target cell lysis over the first 7 days of treatment. Two patients, both with metastatic colon cancer showed transient, objective tumor regression which did not qualify as a partial response. One patient with ovarian cancer had a stable partial response but progressed after 13 courses of treatment. Continuous infusion of TNF can be safely administered to patients with a maximum tolerated dose of only between 30 and 40 micrograms/M2/day.(ABSTRACT TRUNCATED AT 250 WORDS)

The contemporary behavior analyst, to operate ethically and effectively, must be aware of many more factors affecting behavior than simple consequences. Although the literature demonstrating the effectiveness of active behavior management is impressive, a compelling argument can be made that a great number of behavior problem seen in individuals with developmental disabilities may be attributable to factors other than consequences. Our experience has been more often than not that physiological, organic, medication, or situational variables are the actual culprits in maladaptive behavior. Individuals with severe or profound retardation may respond to aversive features of their environment by displaying noncompliance, tantrums, aggression, or self-injurious behavior. These antecedents can affect their behavior just as powerfully as can the consequences of their behavior. Behavior analysts must become sensitive to these potential factors and be prepared to employ behavioral diagnostic strategies in the search for the causes of maladaptive behavior. Finally, they must be prepared to design rather unconventional passive behavior management treatment programs involving the manipulation of the antecedent environment. In the case of Carrie, from the example at the beginning of this paper, the analysis yielded the hypothesis that her face scratching was a reaction to sinus blockage caused by seasonal allergies. Her treatment involved daily dosages of antihistamines administered by our nurses and subsequent elimination of the scratching. Tom was found to be suffering from "wheelchair fatigue." When he was allowed to recline on other surfaces (e.g., bean bag chair, mat, bolster) on a regular basis, he did not attempt any form of self-injury. Melissa was found to have a severe case of Pre Menstrual Syndrome as well as seizure disorder, and was treated with the appropriate medications. Her headbanging was reduced to a few minor incidents per month. Walter's tantrums on closer inspection seemed part of a chain of behavior leading to seizure-like attacks. Preliminary evidence suggests that when he is treated with phenobarbital the tantrums and aggression disappear. And finally, Debbie was found to be very sensitive to a variety of discomforting events. She would cry, sob, and scream when she was wet, thirsty, hungry, and tired. Changing her regularly, offering her water every hour and extra snacks in the morning as well as short naps in the early afternoon eliminated the crying and sobbing. She now participates with the other clients and seems to enjoy the house activities.(ABSTRACT TRUNCATED AT 400 WORDS)

1. The anticonvulsant potency of vigabatrin (gamma-vinyl GABA, GVG) was studied in an open trial in a group of 21 mentally handicapped patients with drug-resistant epilepsy. 2. With this treatment one third of these patients had more than 50% reduction in seizure frequency. The anticonvulsant effect appeared during the first month of therapy and was maintained during a 7-month study. The side effects were mild: mainly tiredness, aggressiveness, and ataxia. Other anticonvulsant drugs remained at baseline levels during GVG therapy. GVG was not found to modulate EEG recordings. 3. According to our results, GVG is effective for treating intractable epilepsy in mentally handicapped patients.

Episodic conjugate tonic upgaze unassociated with seizures or downgaze palsy was noted in three infants during the first months of life. With age, the episodes became shorter and less frequent and were most notable during periods of fatigue or illness. This phenomenon may be analogous to transient tonic downward deviation of the eyes in healthy infants.

A 60-year-old woman who for many years had been taking salicylate-containing tablets for headaches, was admitted to hospital, in a somnolent state, because of increasing weakness, tiredness, memory and speech disorders, and tinnitus. Laboratory tests revealed a decompensated metabolic acidosis (pH 7.25), renal insufficiency (creatinine 2.3 mg/dl) and a decreased Quick value (63%). Whole-blood acetylsalicylic acid concentration was markedly elevated to 330 micrograms/ml. After treatment of the acidosis with bicarbonate and forced diuresis she at first regained consciousness, but clouding of consciousness again occurred eight hours later progressing to coma with unequal pupils and seizure potentials in the electroencephalogram. Status epilepticus without motor component was diagnosed, perhaps the result of a dysequilibrium of acid-base balance between blood and cerebrospinal fluid. The signs and symptoms were quickly reversed under treatment with clonazepam.

A case of hyponatremia is presented with water intoxication due to treatment with oxcarbazepine (OxCZ). The patient was admitted because of exceeding dullness and increasing seizures. Low values for serum sodium and osmolality were found. Simultaneously with the reduction in OxCZ, values of sodium and osmolality increased, normalizing on discontinuation of the drug, and the exceeding tiredness as well as the generalized seizures disappeared. Low values of arginine-vasopressin were found, suggesting that the mode of action of OxCZ was directly or indirectly at the level of the kidney.

Thirty-six children with epilepsy resistant to conventional treatment were treated with bromides in addition to the current therapy. Six out of 19 cases with prevailingly or exclusively generalized tonic-clonic seizures became seizure-free and in 9 cases a reduction in seizure frequency of more than 50% was achieved. Freedom from seizures could not be obtained in 13 cases, who had frequent minor seizures in addition to generalized tonic-clonic seizures. In some, minor seizures were even activated. Tonic and focal seizures showed no response. Side effects were observed in one-third of the cases (acne, loss of appetite, loss of weight, fatigue) but in no case they did become intolerable. Fifty to 80 mg potassium bromide per kg body weight seems to be an effective daily dose range. There is a preferential indication of bromides for patients suffering from early onset epilepsy with generalized tonic-clonic seizures and/or alternating hemi-grand mal, for whom other treatment is ineffective. This disorder is characterized by a high familial incidence of epileptic seizures, onset between 6 months and 3 years of age, normal development until the onset of seizures, generalized tonic-clonic seizures and often alternating hemi-grand mal, seizure precipitation by fever, and occasional combination with or transition to myoclonic-astatic and/or myoclonic seizures. EEG is often normal or shows slight slowing in the initial phase; later it shows theta rhythms and generalized spikes and waves. Especially, if the onset is during the first year of life, the course of the epilepsy is often unfavourable.

Of over forty known epileptogenic mechanisms, some eight involve transient conditions, the regulation of which necessarily involves the understanding cooperation of the patient/parents. Tension states, alterations of the wake-sleep cycle, fatigue and sleep deprivation, CNS stimulation by sensory or drug means, and shifts of the water and acid-base balances constitute the bulk of such seizure-inducing factors. The relative lack of CNS homeostatic control, due to immature development of the blood-brain barrier and cerebral maturation, serve to exaggerate these problems in childhood. In a referred group of 150 refractory epileptic children, the seizure-inducing mechanisms were found to be important (50% reduction of seizure incidence) in 20% and to be of "crucial" importance (complete control) in an additional 14%. These results indicate the importance of such mechanisms in selected children with epilepsy, who were only marginally or inadequately controlled by drug therapy. Reviews of the literature have suggested that this more comprehensive approach to the therapeutic management of epilepsy has not been adequately exploited.
