We report on the clinical efficacy of a slow-release formulation of bromocriptine studied in a multi-center, double-blind trial using standard bromocriptine as the control. We randomly allocated enrolled patients (N = 243) to either the slow-release or normal bromocriptine group. Sixty of them were de novo patients. The maintenance dose of slow-release bromocriptine was 14.2 +/- 0.7 mg/d and that of standard bromocriptine 13.5 +/- 0.7 mg/d (mean +/- SE). The slow-release formulation was taken twice and the standard three times a day. Forty-one percent of the patients treated with the slow-release bromocriptine and 32% of the patients treated with the standard bromocriptine showed moderate or marked improvement in the global improvement rating. There were no serious side effects, and the frequency of vomiting and epigastric discomfort was lower in the patients treated with the slow-release bromocriptine. Clinical efficacies for tremor, rigidity, akinesia, and gait disturbance were comparable between the two drugs tested. The slow-release bromocriptine seems to be a valuable drug for the treatment of Parkinson's disease with less severe side effects than regular bromocriptine.

The DSM-III-R criteria for uncomplicated alcohol withdrawal require the presence of coarse tremor of the hands, tongue, or eyelids plus one of a number of other clinical features. We examined the validity and other characteristics of these items in 137 patients in pure alcohol withdrawal using the reliable and valid Clinical Institute Withdrawal Assessment for Alcohol. The DSM-III-R items of hand tremor amplitude, nausea or vomiting, headache, transient hallucinations, autonomic hyperactivity (increased pulse or sweating), and anxiety correlated significantly with total score and significantly indicated clinical severity. Addition of an "agitation" item improved the correlation. The diagnostic accuracy is greater than 95% if any two or more items are present. The number of positive items, of which tremor can be one, to grade clinical severity shows that a score of 2 indicates "very mild"; 3, "mild"; 4, "moderate"; and 5, "severe.". We propose that an Alcohol Withdrawal Diagnostic Inventory and a DSM-III-R-compatible brief Clinical Institute Withdrawal Assessment for Alcohol are useful for clinical research, where graded symptom characterization is needed. Our data may be helpful in the development of criteria for DSM-IV.

A case of hypertrophic cranial pachymeningitis was reported. A 58-year-old female presented the symptoms of headache and vomiting. At the age of 27, she had suffered from tuberculosis. Neurological examination on admission revealed bilateral papilledema, bilateral hearing disturbance, right hypoglossal nerve palsy, ataxic gait, and bilateral intentional tremor. CT scan showed dilatation of the lateral and third ventricles, and compression of the fourth ventricle with marked enhancement of cerebellar tentorium. A ventriculoperitoneal shunt was installed bringing about improvement in bilateral papilledema, ataxic gait, and bilateral intentional tremor. One month later, ataxic gait and bilateral intentional tremor recurred, and monoparesis of the left upper extremity developed. MRI demonstrated hypertrophic dura mater in the posterior fossa and compressed cervical spinal cord. Decompressive surgery was performed bringing about remarkable clinical improvement. The pathological specimen showed thickening of the dura mater with concentric layers of dense fibrous tissue infiltrated with plasma cells. A diagnosis of hypertrophic cranial pachymeningitis was established. Three years later, the clinical features were found unchanged, but contrast enhancement of cerebellar tentorium had progressed markedly. Hypertrophic pachymeningitis is a uncommon disease. But it should be noted that intracranial involvement is very rare. The etiology, symptomatology, neuroradiology, and treatment are discussed and the literature is reviewed.

Four mature infants developed intracranial haemorrhage at ages from ten hours to five weeks. No predisposing or provoking factors could be demonstrated. The symptoms were apnoea, vomiting, pyrexia, irritability, tremor, hypertonicity, seizures and tense fontanelle. The diagnosis was established by ultrasound scanning and confirmed by computed tomographic scanning. The infants developed hydrocephalus requiring treatment. During the period of observation, these infants showed normal psychomotor development and the neurological findings were normal.

Violent shaking causes severe injury in infants, but the diagnosis of shaken baby syndrome is often difficult to make because of the lack of obvious external signs. Consultations by other specialists may not be helpful, since the findings of most organ systems, taken in isolation, are usually nonspecific. Shaken baby syndrome should be considered in infants presenting with seizures, failure to thrive, vomiting associated with lethargy or drowsiness, hypothermia, bradycardia, hypertension or hypotension, respiratory irregularities, coma or death. Shaken babies are usually less than one year old, and most are under six months of age. Head injury (notably subdural hemorrhage) and retinal hemorrhages are the hallmarks of the syndrome.

According to the hypothesis that the development of physical dependence on and tolerance to opiates depends on the inhibition by opiates of L-asparaginase and L-glutaminase activities in the brain, and the blockade by opiates of the aspartatergic/glutamatergic receptors especially NMDA, four female and fourty-four male heroin addicts were included in a double-blind clinical trial. Four mg chlorpromazine (CPZ) was administered every hour and 10 mg diazepam (DIA) every 6 hours to a group consisting of two female and nineteen male inpatients. The remaining subjects received 15 mg non-opioid antitussive dextromethorphan (DM) instead of CPZ. The withdrawn addicts were controlled twice a day and yawning, lacrimation, rhinorrhoea, perspiration, goose flesh, muscle tremor, dilated pupils, anorexia, joint and muscle aches, restlessness, insomnia, emesis, diarrhea, craving and rejection of smoking as abstinence syndrome signs were observed and rated on a scale of 1, 2 and 3 points according to their intensity. All signs, except perspiration and emesis, were significantly less intense in the group given DM + DIA than CPZ + DIA. The other plus points included the immediate stop of craving and the early onset of smoking in DM + DIA group. The results are considered to be supporting evidence for the hypothesis emphasizing the blockade of NMDA receptors by opiates in opiate addiction. Furthermore, the decrease caused by non-opioid NMDA antagonists in the responsiveness of NMDA receptors appears very promising for the treatment of opiate addicts.

The Isoparaffins covered in this manuscript are branched aliphatic hydrocarbons with a carbon skeleton length ranging from approximately C10 to C15. They are used in the manufacture of liquid imaging toners, paint formulations, charcoal lighter fluid, furniture polishes and floor clearners. Potential exposure exists in the petroleum, printing and paint industries. Isoparaffins have a very low order of acute toxicity, being practically non-toxic by oral, dermal and inhalation routes. However, aspiration of liquid isoparaffins into the lungs during oral ingestion could result in severe pulmonary injury. Dermally, isoparaffins have produced slight to moderate irritation in animals and humans under occluded patch conditions where evaporation cannot freely occur. However, they are not irritating in non-occluded tests, which are a more realistic simulation of human exposure. They have not been found to be sensitizers in guinea pig or human patch testing. However, occasional rare idiosyncratic sensitization reactions in humans have been reported. Instillation of isoparaffins into rabbit eyes produces only slight irritation. Several studies have evaluated sensory irritation in laboratory animals or odor or sensory response in humans. When evaluated by a standard procedure to assess upper airway irritation, isoparaffins did not produce sensory irritation in mice exposed to up to 400 ppm isoparaffin in air. Human volunteers were exposed for six hours to 100 ppm isoparaffin. The subjects were given a self-administered questionnaire to evaluate symptoms, which included dryness of the mucous membranes, loss of appetite, nausea, vomiting, diarrhea, fatigue, headache, dizziness, feeling of inebriation, visual disturbances, tremor, muscular weakness, impairment of coordination or paresthesia. No symptoms associated with solvent exposure were observed.(ABSTRACT TRUNCATED AT 250 WORDS)

The in vivo neurophysiological interactions of the non-competitive NMDA receptor antagonist MK801 with the High Pressure Neurological Syndrome have been investigated in the primate Papio anubis. A hyperbaric chamber was used to achieve environmental pressures of 61 ATA (atmospheres absolute) over a period of 5 hr. Eight animals underwent 2 compressions each, one following pretreatment with 0.03 mg/kg (i.v.) MK801, the other a control. Half of the animals received MK801 on their first exposure. Mild signs of the high pressure neurological syndrome, e.g. paw and limb tremor were first observed between 10 and 20 ATA and more severe signs, e.g. whole body tremor, myoclonus and vomiting, appeared after 50 ATA. The onset pressures for the various signs were increased by 10-17 ATA when the animals received MK801 (P = 0.06) and the severity of the signs, over the whole range of pressures at which they appeared, was significantly reduced (P less than 0.001). Additional experiments showed that MK801 afforded considerable protection, at pressures up to 81 ATA, but doses larger than those used for the main experiment produced signs of tranquilisation and sedation. Changes in the EEG were observed in channels associated with the frontal, parietal and occipital regions. Amplitude and frequency spectra were calculated and trends with pressure in the 4 conventional wavebands were analysed. The most striking change was a decrease in amplitude of delta waves (P less than 0.001), which was ameliorated by MK801 (P less than 0.001).

Effects of various types of motion stimuli were compared to investigate optimum method to elicit motion sickness and adaptation in Suncus murinus (suncus). Three different direction of shaking in the horizontal plane, back and forth, right and left and revolving, induced emetic response to the similar extent. However, vertical shaking was far less effective in inducing motion sickness. Mild and severe horizontal shaking (15 min per day) was continued for 14 days and emetic response to standard motion stimulus was compared before and after the training. The severe daily acceleration strongly depressed the susceptibility to motion stimulus. The mild acceleration which was not emetic stimulus in itself also remarkably attenuated the vomiting response to standard motion stimulus. These results indicate that 1) the emetic responsiveness of the suncus does not depend on the modes of shaking as long as the direction is in the horizontal plane, 2) the suncus is relatively refractory to the vertical linear acceleration and 3) the adaptation to motion stimulus does not develop on the latest peripheral steps of the vomiting reflex pathways.

A five-year-old male was admitted to the hospital with generalized seizures. Enlarged lymph nodes raised the suspicion of cat-scratch disease. The diagnosis was confirmed by a positive history of a cat bite, typical histopathologic findings in the biopsy of the lymph nodes, and a positive skin test. Brain CT scan and LP were repeatedly normal. The clinical course was remarkable for recurrent episodes of status epilepticus refractory to usual anticonvulsant therapy and prolonged encephalopathy consisting of mental confusion, hemiparesis, tremor, chorea, and vomiting. All neurologic symptoms gradually resolved within nine months, without sequelae. Cat-scratch encephalopathy should be suspected in a child presenting with status epilepticus and enlarged lymph nodes. Aggressive and prolonged anticonvulsant therapy is strongly recommended.
