INTRODUCTION First aid oxygen (FAO2) has been widely used as an emergency treatment for diving injuries, but there are few studies supporting its efficacy. METHODS 2,231 sequential diving injury reports collected by the Divers Alert Network (DAN) Injury database from 1998 to 2003 were examined. RESULTS 47% (1,045) of cases received FAO2. The median time to FAO2 treatment after surfacing was...

Neurological complications of heroin addiction have occurred only sporadically in the United Kingdom. We report the case of a young female patient who developed an acute polyradiculoneuropathy when she recommended intravenous heroin after four years abstinence. Another possible aetiological factor was a preceding flu-like illness but, after full investigations, we concluded that heroin abuse wa...

A case of spinal epidural abscess following epidural anesthesia is described. Gadolinium-enhanced magnetic resonance images were essential in diagnosis of the abscess without frank pus formation, in defining the extension of the infection, and in assessing the therapeutic effect. The patient was successfully treated non-operatively before neurological symptoms developed and full recovery was ac...

Chest wall chondrosarcomas are a rare cause for an anterior mediastinal mass. Commonly patients present with a painless palpable mass with a third of patients describing diffuse chest pain. We present a patient with an anterior mediastinal chest wall chondrosarcoma presenting with neurological symptoms and flushing. As more of these cases are seen and reported this rare entity is more likely to...

OBJECTIVE To evaluate the prevalence of the urinary excretion of BKV and JCV in HIV-infected patients without neurological symptoms. METHODS Urine samples from HIV-infected patients without neurological symptoms were tested for JC virus and BK virus by PCR. Samples were screened for the presence of polyomavirus with sets of primers complementary to the early region of JCV and BKV genome (AgT)...

Neuroimaging studies for persons in the National Collaborative Chicago-Based Congenital Toxoplasmosis Study (NCCCTS) with symptoms and signs referable to the spinal cord were reviewed. Three infants had symptomatic spinal cord lesions, another infant a Chiari malformation, and another infant a symptomatic peri-spinal cord lipoma. One patient had an unusual history of prolonged spinal cord sympt...

Down-beating positional nystagmus is typically associated with central nervous system disease. Anterior canal benign paroxysmal positional vertigo (AC-BPPV) can mimic down-beating positional nystagmus of central origin, particularly when it is bilateral. Factors that increase the probability of bilateral AC-BPPV include a history of bilateral multicanal BPPV, transient down-beating and torsiona...

Cocaine and its principal metabolite, benzoyl ecgonine, were isolated from the urine of four hospitalized children who had been exposed to the smoke of freebase cocaine ("crack") used by their adult caretakers. Two of the children had transient neurological symptoms (drowsiness and unsteady gait) and two had seizures whose cause could not be determined by laboratory investigation. Passive cocai...

INTRODUCTION The frequency of seizures in patients with multiple sclerosis (MS) ranges from 1.5% to 7.8% and is considerably more common than chance events. The etiopathogenesis of seizures in MS is still poorly understood. METHOD A review of the literature on seizures and MS using PubMed. RESULTS Cortical gray matter involvement appears to be an all-too-common pathological finding in MS to...
