In nine cases of phencyclidine hydrochloride poisoning, early signs of overdose included drowsiness, nystagmus, miotic pupils, blood pressure elevation, increased deep tendon reflexes, ataxia, anxiety, and agitation. In more severe cases, seizures, spasticity, and opisthotonos were seen in addition to deep coma and respiratory depression. Treatment included removal by emetics or lavage, hydration, and a quiet, reassuring environment. Spasticity, agitation, and ocular manifestions responded to diazepam. Psychiatric intervention was instituted after the patients were stable and no longer agitated.

Delayed neurological deterioration following anoxia is known to result from carbon monoxide exposure. However, it may also occur with anoxia of other types as well. The present report describes a case of delayed postanoxic encephalopathy with bilateral striatal lesions demonstrated by magnetic resonance imaging. A 27-year-old man exhibited anoxic anoxia caused by upper airway obstruction following general anesthesia for shoulder fracture surgery. Initially he was delirious and markedly excited for one day and became apparently normal for the following three days. Then he relapsed into delayed neurological deterioration with speech and gait disturbance, clumsiness of hand, pyramidal signs and metamorphopsia. Thereafter, he became bed-ridden and fell into semicomatose state with marked motor restlessness, involuntary movement of the tongue and decorticate posture. Twenty-five days later he had a second recovery period after hyperbaric oxygenation that lead to the sequelae with speech and motor disturbances and mild mental changes. I examined the present case as an expert witness in a civil suit eleven years after initial anoxia. The patient showed slight intellectual impairment and personality change. Impairment in figure-ground differentiation and disorders of spatial thought were also observed. Neurological examination revealed anisocoria, dysarthria with acquired stuttering, disturbances of fractionated movement of fingers, writer's cramp and Babinski's sign bilaterally. Postural dystonia of both hands and fingers, rigidity and spasticity of all extremities were also present. Magnetic resonance imaging (MRI) showed bilateral lesions of the corpus striatum, especially of the putamen. Some portion of the caudate nucleus was also involved. Cerebral cortices and white matter were slightly atrophic. From the above clinical course and neurological findings, we diagnosed the present case as delayed postanoxic encephalopathy. Ginsberg (1979) noted that in cases of anoxia not related to carbon monoxide, diffuse demyelinative changes of cerebral hemispheral white matter tended to be associated with relapsing clinical course, and gray matter injury was only seen in a few cases. MRI findings in the present case suggest that main site of the lesion to be in gray matter of the corpus striatum. In this respect, the present case is considered to be noteworthy.

Positioning and seating are important for premature and young infants with tonal problems. Positioning with pillows and sandbags, the use of special handling techniques (Bobath's neural developmental treatment), as well as other specialized approaches, have not proved satisfactory in reducing tone or spasticity in these infants. We developed an adaptive seat designed to reduce extensor tone through proper positioning. This seat has also been helpful in diminishing agitation. Without these benefits, infants are often immobilized in extension and cannot actively explore their environments. Diminution in agitation has also been important in increasing interaction with nurses.

Stereotaxic subthalamotomy of 55 patients with cerebral palsy gave a good result in 65% of the selected cases. The result was uncertain in 15 and poor in 20%. An independent socio-medical follow-up study confirmed the clinical finding. The more rapid the involuntary movements, the better was the effect of subthalamotomy. Intention tremor was the most suitable symptom for stereotaxic treatment. Rigidospasticity was alleviated in the distal muscles only. Speech and gait were often improved. Good results were obtained in patients with normal intelligence, while feeble-minded patients did not benefit from the operation. Subthalamotomy was followed by transitory side-effects in 20%, of which increased involuntary movements on the ipsilateral side and mental restlessness were the most frequent. The operation had no mortality. Spinal longitudinal myelotomy effectively relieved the spasticity of the lower limbs in the three patients operated upon.

Baclofen is widely used in the treatment of spasticity of spinal origin. It is relatively free of side effects or toxic actions on the nervous system or other organs. Agitation, personality change, and auditory and visual hallucinations have been described following its abrupt withdrawal. One patient with generalized seizures and one with complex partial seizures after baclofen withdrawal have been reported. This paper presents a patient who developed status epilepticus after baclofen withdrawal, and who sustained hypoxic cerebral injury. This observation further emphasizes the possibility of infrequent complications of baclofen therapy, and the advisability of gradual changes in baclofen dosage.

Changes in the delivery of health care have resulted in new sites for rehabilitation of patients with severe brain injury (BI). Adjustments in the training of resident physicians in physical medicine and rehabilitation are likely to ensue. We utilized Likert scales and open-ended questions to survey residents who were assigned over a 2(1/2)-year period to a subacute BI rehabilitation unit (SRU). Residents were surveyed about their desire to participate in a SRU training site, and the usefulness of such a rotation, and compared the rotation to traditional settings in which patients with similar diagnoses were treated. The results indicated that significant positive changes in residents' attitudes towards this type of training site occurred (p = 0.01). The rotation was felt to be useful (p = 0.008) despite initial misgivings. Positive educational aspects were exposure to the unique problems of patients with severe BI (e.g. spasticity and agitation) and a sense of independence and competence in leadership roles. Problematic aspects included the management of medically unstable patients without supportive resources, and a lack of nurses trained in rehabilitation principles. Training of residents in the rehabilitation management of patients with severe BI can be perceived as a valuable educational experience by trainees.

Glutamate is the major excitatory neurotransmitter of the central nervous system. Besides its importance in many physiological processes, increased glutamate release and subsequent excessive stimulation of the various glutamate receptors are thought to play critical roles in the pathophysiological mechanisms underlying many neurologic diseases. Experimental data suggest that blockade of glutamate receptors or inhibition of glutamate release has positive effects in many disease models. Glutamate antagonists are already in clinical use for the treatment of Parkinson's disease, epilepsy, spasticity, and neuropathic pain. Overall, glutamate antagonists have not been found clinically effective for neuroprotective treatment of cerebral ischemia or chronic neurodegenerative diseases, with one exception. Side effects of glutamate antagonists can be mainly attributed to central mechanisms and include psychosis, agitation, and disorientation. It is to be hoped that further development of new glutamate antagonists that block disease-relevant subtypes of glutamate receptors will lead to more effective drugs with fewer side effects.

Intrathecal baclofen is used as a muscle relaxant and antispasmodic in cases of spasticity resulting from central nervous system trauma. The baclofen withdrawal syndrome may include hyperthermia, tachycardia, hypertension, seizures, altered mental status, and psychomotor agitation. We report a case in which the removal of a baclofen pump lead tothe development of severe withdrawal symptoms despite oral baclofen replacement therapy. In order to avoid the development of withdrawal, adequate doses of GABA agonist agents should be administered immediately prior to, and following, baclofen pump removal.

Patients with amyotrophic lateral sclerosis (ALS) have symptoms of progressive muscle weakness, of disturbed speech and swallowing, and in the terminal phase those of respiratory weakness. Treatment options, in particular those for excessive weight loss and respiratory weakness, should be introduced to the patients and their families when the patient is emotionally capable and before dysarthria severely hampers communication. Special equipment for keeping the patient as mobile as possible should be made available much earlier than in the case of other diseases of the muscles as in ALS progression is much faster. Cramps, pathological crying or laughter, spasms, and spasticity can all be treated by medication. When speech can no longer be understood, adaptive strategies such as sign language, mime, posture and communication apparatus varying from a note pad to advanced computer systems can be used. Sialorrhoea, caused by difficulty swallowing with its accompanying danger of aspiration can be halted by the use of medication, by radiotherapy and by the injection into the salivary glands of botulin A toxin. Weight loss, also a result of dysphagia, can be avoided by eating frequent small meals or if necessary performing a percutaneous endoscopic or radiological gastroscopy. Excess mucus in the respiratory tract can be treated with anticholinergics. Difficulty in coughing up thick and sticky mucus cannot always be adequately helped. Respiratory weakness is treatable by external respiratory supportive therapy using a nasal mask, as well as invasive respiratory support via a trachcostoma and by treating the symptoms of respiratory weakness. The latter form of treatment is palliative and forms part of terminal care. During the terminal phase restlessness, anxiety, pain, and dyspnoea require the most attention. Treatment requires careful multidisciplinary cooperation.

An initial report on the therapeutic application of delta 9-THC (THC) (Dronabinol, Marinol) in 8 children resp. adolescents suffering from the following conditions, is given: neurodegenerative disease, mitochondriopathy, posthypoxic state, epilepsy, posttraumatic reaction. THC effected reduced spasticity, improved dystonia, increased initiative (with low dose), increased interest in the surroundings, and anticonvulsive action. The doses ranged from 0.04 to 0.12 mg/kg body weight a day. The medication was given as an oily solution orally in 7 patients, via percutaneous gastroenterostomy tube in one patient. At higher doses disinhibition and increased restlessness were observed. In several cases treatment was discontinued and in none of them discontinuing resulted in any problems. The possibility that THC-induced effects on ion channels and transmitters may explain its therapeutic activity seen in epileptic patients is discussed.
