Clinical reports on 430 children with acute codeine intoxication are evaluated. Of 234 children who had taken more than 5 mg/kg body-weight, 8 had respiratroy arrest necessitating intubation and artificial ventilation; 2 of them died. In all other cases the intoxication produced one or more of the following symptoms: somnolence, ataxia, miosis, vomiting, rash, swelling, and itching of the skin, but no life-threatening side-effects. Close supervision of respiration is the main principle of management when more than 2 mg codeine/kg body-weight has been taken. Gastric voiding may be useful if done soon after ingestion. Charcoal and purgatives should be given in all cases.

The clinical safety of lamotrigine (LTG), assessed in four completed randomized, double-blind, placebo-controlled crossover trials and an interim analysis of 27 12-month open studies, is discussed. LTG was added to existing antiepileptic drugs (AEDs) of adult patients with refractory epilepsy, using a twice-daily regimen. In the pooled data from the four double-blind studies (n = 92), the incidence of adverse experiences with LTG and placebo did not differ significantly. Two patients were withdrawn on LTG due to adverse experiences (one rash, one nausea and vomiting). In the open studies (pooled data; n = 572) the most commonly reported adverse experiences were dizziness, diplopia, somnolence, headache, ataxia, and asthenia (10-14% incidence). Forty-nine patients (8.6%) were withdrawn with adverse events, most commonly for rash (2.3%). No patients were withdrawn from any of the studies with physical, neurological, or ECG abnormalities thought attributable to LTG treatment. Laboratory measures, vital signs, and weight did not show any consistent changes of clinical significance, and no significant changes in plasma concentrations of concomitant AEDs after the addition of LTG were observed.

A 69-year-old woman with classic glucagonoma syndrome had associated progressive neurologic disease manifest as dementia, ataxia, optic atrophy, and lower limb weakness. Visual evoked responses (VERs) were absent bilaterally. After an attempt at resection was unsuccessful, therapy was started with somatostatin analogue (Sandostatin, SMS 201-995). Over the ensuing 3 months, there was a decrease in the plasma glucagon level, resolution of the rash, weight gain, reversal of the dementia, and an improvement in coordination and limb weakness. Subsequent VERs revealed bilateral delayed responses.

Neurological disorder may be the initial manifestation of Lyme disease. Six cases of neurological Lyme disease have been seen in the years 1986-89, five of whom contracted the disease in the West of Ireland. Three presented with a radiculoneuropathy, one with myalgia/fatigue and one with bilateral sixth nerve palsies and ataxia. These cases indicate the spectrum of neurological involvement of Lyme disease in Ireland which reflects that seen in Europe. They also highlight some of the problems in diagnosis which sometimes necessitate treatment while awaiting serological studies. We feel even in the absence of a history of tick-bite or rash, Lyme disease should be considered in the differential diagnosis of many neurological disorders, especially in patients from the West of Ireland.

We report the effects of the addition of lamotrigine, a novel antiepileptic drug, to the therapy of 125 patients with severe refractory epilepsy. Forty-five patients (36%) reported adverse experiences and in 19 (15%), the drug was withdrawn. The commonest adverse experiences were diplopia, headache, ataxia, drowsiness, skin rash and deterioration in seizure control. Two patients were withdrawn for other reasons. The remaining 104 patients were followed for a mean of 11 months (range 3-27): 26 (25%) of these showed a marked improvement in seizure frequency (a 50% or more reduction when compared with the pre-trial period), but no patient was rendered seizure-free. Tolerance to the effects of the drug was not seen.

Plasma phenytoin and phenobarbitone levels were estimated in 123 adult Ethiopian epileptics by gas-liquid chromatography. Thirty four (38.2%) of the patients on phenytoin, and 52 (52%) of those on phenobarbitone, had plasma levels in the conventional therapeutic ranges of 10-20 micrograms/ml and 10-30 micrograms/ml respectively. Of the 89 patients who were taking phenytoin either singly or combined with phenobarbitone, motor disturbances (ataxia and nystagmus) were seen in 31 (34.8%) and dysmorphic and idiosyncratic side effects including gum hypertrophy, hirsutism, acne and skin rash in 37 (41.6%). Subnormal serum calcium levels were noted in 15 (30.6%) and high alkaline phosphatase was found in 13 (26.5%). Phenobarbitone was found to be an effective anticonvulsant (78.1% seizure control rate), with adverse effects of sedation and intellectual depression. Seizure control was achieved in 77.1% of patients on a single drug as opposed to 55.6% on combination of phenytoin and phenobarbitone (p less than 0.05). The overall seizure control rate was 66%.

Biotinidase deficiency is the primary biochemical defect in late-onset multiple carboxylase deficiency and an autosomal recessive disorder and characterized by seizures, ataxia, alopecia and skin rash. We describe a colorimetric semiquantitative method for screening for biotinidase activity from dried samples of whole blood spotted on filter papers. The administration of biotin to affected children can be a lifesaving procedure and can prevent irreversible neurologic damage.

Aminoglutethimide (AG) was administered as palliative therapy in 112 patients with metastatic breast cancer. In 36 patients, the dose level was 1000 mg/day; 76 patients received a dose level of 500 mg/day. Patients with brain or liver metastasis were excluded, as were patients with tumors determined to be negative for estrogen receptors. Objective regression was observed in 35 (31%) patients, with the duration of response ranging from 4 to 36 + months (mean, 12 months; median, 10 months). Response was observed in 11 of 31 (35%) patients with soft tissue metastasis; 16/59 (27%) patients with osseous metastasis; and 8 of 22 (36%) having visceral metastasis. In 93 patients with positive estrogen receptor (ER), 33 responded (35%), whereas in 19 patients with unknown ER status, two responded (11%). Response to previous treatment with tamoxifen (TAM) had occurred in 31 patients; of these, response to AG was noted in 11 (35%). Of 24 patients failing to respond to prior treatment with tamoxifen, four (17%) responded to subsequent therapy with AG. Thirteen patients had previously received combination chemotherapy, and response to AG was noted in two (15%). The side effects observed in this study included skin rash in ten patients, fever in eight, somnolence in three, weakness and dizziness in one, headache in one, insomnia in one, dyspnea in one, and ataxia in one. Treatment had to be discontinued in eight patients, due to the severity of the side effects. As expected, patients receiving AG at the lower dose level of 500 mg/day experienced fewer and less severe side effects than those treated with the higher dose. The response rate in the 1000 mg/day group was 10/36 (28%) and in the 500 mg/day group, it was 25/76 (33%). The lower dosage was better tolerated without apparent compromise in therapeutic efficacy.

Hartnup disease is an inborn abnormality of renal and intestinal transport involving the neutral amino acids. Intermittent pellagra-like rash, attacks of cerebellar ataxia and psychiatric disturbance are characteristic symptoms of this disease. We described here a patient with adult-onset Hartnup disease who presented unique neuropsychiatric symptoms but no dermatologic symptoms, and reported features of amino acids transport in this patient and his family. The patient, a man aged 37 years, was referred to us because of lasting daytime bruxism. He is the second child of healthy parents who are first cousin; his elder brother who has been mentally retarded became bed-ridden and died at 32 years of age. His younger brother is completely healthy. Although the patient's development in infancy has been slightly retarded, he completed compulsory 9-year education. At 29 years of age, he experienced episodes of diplopia, ataxic gait and insomnia, and at 33 years of age, of transient stupor. There had been no history of photosensitivity or dermatitis. On neurological examination, there were trunkal ataxia, increased muscular tone and decreased mental activity besides bruxism. These symptoms remained unchanged despite of several medications including trihexyphenidyl, diazepam, halloperidol, tiapride and sulpiride. Two months later, the patient became stuporous; bruxism and hypertonicity became exaggerated. Myerson's sign, sucking reflex and grasp reflex in both hand appeared. There was no dermal lesion. A cranial computed tomography revealed a small calcification in the right frontal subcortical region and a single photon emission tomography indicated possible bifrontal hypoperfusion. Electroencephalograms demonstrated non-specific slowing. Somatosensory evoked potentials and nerve conduction velocities were normal. There were constant indicanuria and amino-aciduria.(ABSTRACT TRUNCATED AT 250 WORDS)

The authors report 2 familial cases of biotin deficiency. The first neurological signs appeared at the age of 2 years in a boy. The diagnosis was established in his sister in the neonatal period. A review of 41 published cases summarizes the neurologic signs (seizures, ataxia, hypotonia and later, developmental delay and deafness) and the cutaneous signs (rash, alopecia). An early treatment with biotin cures or prevents the clinical signs of the disease in most cases.
