A 3-year-old boy developed confusion, generalized tonic-clonic seizures, and sustained ventricular tachycardia following ingestion of an unknown quantity of orphenadrine (Norflex). Although refractory to precordial thump, synchronous cardioversion, and lidocaine, the ventricular tachycardia was reversed by intravenous administration of the tertiary acetylcholinesterase inhibitor physostigmine. We discuss the underlying physiology and manifestations of anticholinergic overdose, the specific manifestations of orphenadrine overdose, and the current recommendations regarding the utilization and toxicity of physostigmine in the treatment of anticholinergic syndromes and orphenadrine intoxication.

A prospective study of the neurological manifestations in all patients with systemic lupus erythematous (SLE) was conducted between February 1985 to January 1989. Excluding herpes zoster infection of peripheral or cranial nerves, post-herpetic neuralgia and migraine, 36 neurological episodes occurred in 33 patients. The presenting symptoms were mental confusion (10), psychosis (five), seizures (six), focal neurological deficit (three), coma (two), headache (five), blurring of vision (three), neuropathy (one) and myelopathy (one). Of these manifestations, only eight episodes were due to primary involvement by SLE: psychosis (two), seizure (two), multiple cerebral infarcts (one), papillitis (one), neuropathy (one) and myelopathy (one). Infection was the most common secondary cause of neurological episodes: all 10 episodes of mental confusion (fungal seven, pyogenic two, tuberculous one, nocardial one); two of six seizures (tuberculous one, pyogenic one); all five headaches (tuberculous meningitis three, cryptococcal meningitis two). The other secondary causes included steroid psychosis (two), hypertensive encephalopathy with seizure (one) and hypertensive retinopathy (one). Three of five cases of focal neurological deficit were due to macrovascular disease rather than to vasculitic infarction. We concluded that cerebral psychosis was a relatively rare presentation in our patients with SLE. In patients who presented with a neurological problem, especially mental confusion, efforts should be made to ascertain the underlying cause, especially if this may be an infection.

A case of Listeria monocytogenes bacteraemia and meningitis with intracerebral abscesses in a girl with acute lymphoblastic leukaemia in relapse is reported. The clinical features included subacute onset with fever and marked irritability followed by seizures, meningism and confusion. The pathogen was isolated from blood and cerebrospinal fluid. Computerised tomography of the brain showed two intracerebral parenchymal localisations, in the left frontal lobe and in the right occipital lobe, respectively. The patient survived this severe infection without neurological sequelae. 2 months later she underwent allogeneic bone marrow transplantation without major complications. This case report should alert pediatric oncologists about the possible occurrence of severe intracerebral listerial infections in the immunocompromised child and suggests that this infection can be treated successfully and should not necessarily preclude continuation of antineoplastic treatments.

Ictal sexual manifestations, like somatosensory genital phenomena, sexual emotions or sexual automatisms during a partial complex seizure, are very rare. So far the literature has above all described cases in adulthood. We report on a 6-year-old boy with partial complex epileptic seizures which led to confusion, oral and genital automatisms and the urge to urinate. During one epileptic seizure with these urogenital manifestations the EEG showed an epileptic rhythmic discharge over the left temporal region.

Multicenter noncomparative trials of intramuscular administration of imipenem/cilastatin for the treatment of a variety of infections requiring multiple-dose therapy are reviewed. Fourteen centers in the United States and 18 centers elsewhere participated in these studies. A total of 686 patients (461 evaluable) were treated worldwide. The severity of the infection was rated as moderate in 58.9%, mild in 37.2% and severe in 0.6%. The most common sites of infection were the skin and soft tissue (36.2%) and intra-abdominal (17.6%). Polymicrobial infections were relatively common (27%). Dosing regimens in evaluable patients were 500 mg every 12 h (45.1%), 750 mg every 12 h (36.2%) and 500 mg every 8 h (18.6%). The overall clinical outcome was favorable (clinical cure or improvement) for 95% or more of the evaluable patients with the various body system infections, except in gynecologic infections where 89% of the evaluable patients had a favorable outcome and for sepsis where the favorable outcome was 76%. Where data were available for analysis (skin and soft tissue infections) there was no difference in favorable clinical outcome among patients with moderate infection treated with 1.0 g/day (95% favorable) compared with 1.5 g/day (94% favorable). The overall bacteriologic eradication rate was 91%. Clinical adverse effects were similar in type but less common in frequency than those noted in other studies with the intravenous formulation, with nausea, vomiting and diarrhea being most common; no instances of seizures or confusion were observed. The laboratory adverse effects were similar to those seen in other studies with the intravenous formulation, with increased liver enzyme values the most common. The intramuscular injection was well tolerated in 87% of the patients and moderately well tolerated in 6.6%. The efficacy and low incidence of side effects of the intramuscular formulation of imipenem/cilastatin are significant advantages in the cost-effective treatment of infections.

In recent years, a differentiation has been made between two syndromes that are characterized by brief abnormal paroxysmal movements occurring principally at night: 1, hypnogenic paroxysmal dystonia (HPD), sometimes considered a particular form of dystonia similar to paroxysmal kinesigenic choreoathetosis, and 2, mesiofrontal epilepsy. Whether HPD is a distinct syndrome is not clear. Twenty-three patients, 11 men and 12 women, were hospitalized between 1985 and 1989 for examination of this type of abnormal paroxysmal movements (APM) occurring at night. In order to clarify the physiopathology of these abnormal nocturnal movement as focal epilepsy or a particular form of dystonia, we analyzed the personal and familial antecedents of all 23 patients, the polygraphic records during waking and sleep periods, and the results of neuroradiological examinations. Four patients were examined by positron emission tomography (PET) using i8F deoxyglucose. Symptoms first appeared between 3 and 28 years of age (M, 10.1) and developed over 1 to 20 years (M, 10.1). APM clearly occurred more commonly (greater than 90%) during sleep, usually during phases of slow-wave sleep. The sleeping patient opened his eyes and the motor signs then variously associated affective facial expression; axial postural modifications; tonic, dystonic or choreic postural movements of the limbs; pedalling; automatisms; disordered agitation and vocalization. The seizure was abruptly interrupted after 10 to 60 seconds. There was usually no postictal confusion. Thirteen patients clearly had clear epileptic antecedents: in 9, generalized tonic-clonic seizures; in 4, focal epileptic status. During nocturnal polygraphic recording, 6 patients presented a generalized seizure following a period of APM.(ABSTRACT TRUNCATED AT 250 WORDS)

Two cases of ictal automatisms of frontal lobe origin are reported. Both two cases had automatisms characterized by abrupt onset and ending, short duration, preservation of consciousness and frequent attacks in cluster. The ictal manifestations included rocking of body and violent thrashing of limbs in prone position with loud screaming. No initial staring or postictal confusion was noted. Interictal EEGs showed spikes in the frontal area. Ictal EEGs began with attenuation of background activity and/or fast rhythmic waves dominant in the frontal area. Just after clinical seizures, high voltage slow waves in bilateral frontal areas and rhythmic alpha waves in the occipital areas were recorded. The EEG findings suggested that the paroxysmal activities were localized in bilateral frontal lobes, not spreading to the temporal lobe.

Leptomeningeal metastasis (LM) of systemic malignancy often give rise to multifocal involvement of the central (CNS) and peripheral nervous system. Signs of CNS dysfunction such as seizures and confusion often overshadow radicular deficits. We report clinical and laboratory evaluations in 10 patients with LM who presented with isolated polyradiculopathy. Our data suggest that electromyography and late response studies are sensitive indicators of radicular dysfunction in patients with LM. These studies are helpful in the early documentation of root involvement when computerized tomography, MRI and myelography are normal.

We describe 5 patients with a relapsing encephalopathy in association with Hashimoto's disease and high titers of anti-thyroid antibodies. The presentation is usually with a subacute onset of confusion, alteration in conscious level, and focal or generalized seizures. The relapsing course, association with myoclonus or tremulousness, and episodes of stroke-like deterioration are characteristic features. The long-term prognosis is favorable with steroid therapy, though additional immunosuppressive therapy may be required. Neurologic investigation typically shows a diffusely abnormal EEG, high CSF protein level without pleocytosis, and normal brain CT and cerebral angiogram. Isotope brain scan may show patchy abnormal uptake. Hashimoto's encephalopathy should be recognized as a definite neurologic entity and added to the list of CNS complications of thyroid disease.

Apart from choriocarcinoma, involvement of the central nervous system (CNS) by gynecologic malignancy is rare. A 10-year retrospective review at the University of Washington Medical Center (Seattle, WA) and Swedish Hospital and Medical Center Tumor Registry (Seattle, WA) identified 14 patients with cerebral metastases from ovarian carcinoma. Median age at diagnosis of cerebral metastases was 52.5 years. Median interval from the diagnosis of ovarian carcinoma to the diagnosis of CNS metastases was 14.5 months. Seven patients had received cisplatin therapy before CNS relapse. Seven patients underwent second-look procedures before developing CNS metastases; in three, results were negative. Eight patients had evidence of extraperitoneal spread to other sites at the time of CNS relapse. Clinical manifestations included motor weakness, seizures, headache, confusion, and speech disturbance. All lesions were contrast enhancing on computed tomography (CT) scans and were located in the cerebral hemispheres. Nine patients had single lesions, five of whom underwent surgical resection of the lesion with histologic confirmation of metastases from the primary site. Median survival was 2 months in patients receiving radiation therapy alone and 17 months in patients who received surgery and radiation. Median survival of the entire series was 3 months. The presence of multiple cerebral metastases or evidence of extraperitoneal spread elsewhere in the body was adversely associated with survival. The prognosis of patients with cerebral metastases from ovarian carcinoma appears poor. However, early diagnosis by routine CT scanning followed by surgical resection and radiation may improve overall survival in a select group of patients.
