A 17 year old high school boy experienced fever and diarrhea, which subsided within 4 days by appropriate medications. Six days later, however, he developed unsteadiness and limb spasm. On the morning of admission, he was found to have drowsiness, dysarthria, gait disturbance and involuntary jerks. When he was brought to the hospital, he was lethargic but could follow simple verbal commands. Frequent involuntary movements manifested by facial grimacings, limb spasms and twitchings with dystonic features were seen. Decorticate posturing was readily elicited by painful stimuli. There was no meningeal irritation sign or gross sensory impairment. The deep tendon reflexes were symmetrically exaggerated with bilateral Babinski signs. Bilateral lateral rectus muscle weakness was found together with mild ptosis and upward gaze limitation. Nystagmus was not present and the funduscopic examination was normal. Immediately he was placed on anticonvulsants, steroid hormone, gamma-globulin and antibiotics as well. A brain CT scan and a CSF examination revealed no abnormality. Meanwhile he continued to show a progressive deterioration associated with fever and status epilepticus, and within 24 hours he lapsed into coma in decorticate posture. An EEG obtained at the 3rd hospital day was compatible with spindle coma. In spite of aggressive treatment he remained febrile and comatous. Therefore, vidarabine (adenine arabinoside) was initiated from the 3rd hospital day for 5 days. Then he began to groan and show frequent choreic movements. For the subsequent 2 weeks he made a slow recovery.(ABSTRACT TRUNCATED AT 250 WORDS)

Blood concentrations and clinical findings in 25 cases of overdose involving chlordiazepoxide (CDZ) alone ("pure") were compared with those in 23 cases of overdose involving ethanol in addition to CDZ ("mixed"). Both groups consisted predominantly of men who were chronic alcoholics. The mean blood CDZ concentrations did not show statistically significant difference between the two groups ("pure," 5 mg/L; "mixed," 6 mg/L). Following "pure" ingestion, patients were usually alert, and the level of consciousness showed no statistically significant correlation with the blood CDZ concentration. In contrast, after "mixed" ingestion patients were usually lethargic, and the level of consciousness correlated significantly with the blood CDZ concentration (P less than 0.05) but not with the blood ethanol concentration. In neither group was coma noted. For both groups the most common physical findings were tachycardia and dysarthria. Nystagmus was much more common following "mixed" ingestion while seizures, hyperreflexia, and hypertension were more frequent after CDZ overdose alone. Most patients were seen only in the emergency room and were discharged. The implications of these findings are discussed.

In 1,000 cases of phencyclidine (PCP) intoxication evaluated at the time of first examination in an emergency department, the incidence of "typical" findings was found to be lower than has been reported previously. Nystagmus and hypertension occurred in only 57% of our cases; some patients had only one of these findings and many had neither. The incidence of violence was 35%; bizarre behavior, 29%; and agitation, 34%. Changes in sensorium consisted of coma, lethargy/stupor, and acute brain syndrome; however, 46% of patients were alert and oriented. Motor signs included grand mal seizures, generalized rigidity, localized dystonias, catalepsy, and athetosis. Profuse diaphoresis, hypersalivation, bronchospasm, and urinary retention occurred in less than 5%. A small percentage had severe disturbances in vital signs, including three cases (0.3%) of cardiac arrest and 28 cases (2.8%) of apnea. Hypoglycemia and elevated serum CPK, uric acid, and SGOT/SPGT were common. Urine PCP levels did not correlate with the severity of the clinical findings.

We conducted a masked, crossover, therapeutic trial of gabapentin (1,200mg/day) versus memantine (40 mg/day) for acquired nystagmus in 10 patients (aged 28-61 years; 7 female; 3 multiple sclerosis [MS]; 6 post-stroke; 1 post-traumatic). Nystagmus was pendular in 6 patients (4 oculopalatal tremor; 2 MS) and jerk upbeat, hemi-seesaw, torsional, or upbeat-diagonal in each of the others. For the group, both drugs reduced median eye speed (p < 0.001), gabapentin by 32.8% and memantine by 27.8%, and improved visual acuity (p < 0.05). Each patient improved with 1 or both drugs. Side effects included unsteadiness with gabapentin and lethargy with memantine. Both drugs should be considered as treatment for acquired forms of nystagmus.
