Fifty-seven cases of meprobamate ingestion from 1974 through 1979 were reviewed. Serum meprobamate concentrations, clinical findings, and epidemiologic data were studied to determine the present status of the abuse of this compound. The average patient was a 37-year-old woman who ingested meprobamate and at least one other drug (usually a benzodiazepine, a barbiturate, ethanol, or an opiate) in a suicide attempt of gesture. She arrived at the hospital either alert or lethargic with equal frequency. Half of the time she was seen only in the emergency room, and half of the time she was hospitalized. She was usually treated with supportive care alone and survived the ingestion. Serum meprobamate concentrations exceeding 12 mg/dl were consistent with coma. Dysarthria, hypotension, tachycardia, and ataxia were the most common physical findings. Meprobamate addiction was present in six patients.

A 54-y-old man ingested 2 g of bulk laboratory diazepam and was treated with activated charcoal, enhanced diuresis and flumazenil infusion. The treatment resulted in awakening, but the patient had drowsiness, dysarthria, diplopia, and dizziness for 9 d. Blood levels of diazepam and its main metabolite, nordiazepam, were obtained for 1 mo. The half-lives in this benzodiazepine overdose were longer than those seen with therapeutic doses. Benzodiazepines should not be readministrated when patients awake after suicide attempts.

A 35-year-old female ingested a lethal dose of potassium cyanide in a suicide attempt. She survived following antidote therapy and intensive care. Following artificial coma she presented with an agitative state for several days followed by akinetic mutism, buccofacial and ideomotoric aphasia. Severe rigid-akinetic syndrome, dysarthria, dysphagia and generalized dystonia developed weeks later. MRI revealed lesions in the caudate and lentiform nuclei, precentral cortex, and cerebellum. SPECT by [123-I] 2 beta-carbomethoxy-3-beta-(4-iodophenyl)-Tropan on two occasions revealed progressive loss of dopamine transporter suggestive of nigral neuronal apoptosis. Striatal and frontal hypometabolism and hypoperfusion were found by FDG-PET and HMPAO SPECT.

Subthalamic nucleus deep brain stimulation (STN-DBS) is effective for medically refractory Parkinson's disease. We retrospectively analyzed complications in 180 consecutive patients who underwent bilateral STN-DBS. Surgery-related complications were symptomatic intracerebral hemorrhage in 2, chronic subdural hematoma in 1, and transient deterioration of medication-induced psychosis in 2 patients. Device-related complications involved device infection in 5, skin erosion in 5, and implantable pulse generator malfunction in 2 patients. All of these patients required surgical repair. Surgery and device-related complications could be reduced with increased surgical experience and the introduction of new surgical equipment and technology. Treatment or stimulation-related complications were intractable dyskinesia/dystonia in 11, problematic dysarthria in 7, apraxia of eyelid opening (ALO) in 11, back pain in 10, and restless leg syndrome in 6 patients. Neuropsychiatric complications were transient mood changes in some, impulse control disorder in 2, severe depression related to excessive reduction of dopaminergic medications in 2, rapid progression of dementia in 1, and suicide attempts in 2 patients. Most complications were mild and transient. Dysarthria and ALO were the most frequent permanent sequelae after STN-DBS. Treatment-related adverse events may be caused not only by the effect of stimulation effect but also excessive reduction of dopaminergic medication, or progression of the disease. In conclusion, STN-DBS seems to be a relatively safe procedure. Although serious complications with permanent sequelae are rare, significant incidences of adverse effects occur. Physicians engaged in this treatment should have a comprehensive understanding of the probable complications and how to avoid them.
