A 24-year-old pregnant woman started to have hyperemesis gravidarum 6 weeks before admission. Four weeks later she had vertigo, diplopia, staggering gait, mild dyspnea, dysphagia, and incontinence of urine. On admission she presented with ophthalmoplegia, ptosis, ataxia, decreased tendon reflex, and memory disturbance. Brain magnetic resonance imaging revealed abnormal intensities in medial thalamic-hypothalamic regions and the periaqueductal area, and she was diagnosed with Wernicke's encephalopathy. Urodynamic studies revealed decreased bladder volume and detrusor hyperreflexia. Six weeks after the administration of 100 mg/day of thiamine, urge incontinence gradually recovered, together with neurological signs. Lesions of the medial thalamic-hypothalamic area and the periaqueductal gray matter seemed to be mainly responsible for micturitional disturbance in our patient with Wernicke's encephalopathy.

Adult-onset myasthenia gravis is an acquired autoimmune disorder of neuromuscular transmission in which acetylcholine receptor antibodies attack the postsynaptic membrane of the neuromuscular junction. Although the cause of this disease is unknown, the role of immune responses in its pathogenesis is well established. Circulating acetylcholine receptor antibodies are present in 80% to 90% of patients with the generalized form of myasthenia gravis. Most patients have ptosis, diplopia, dysarthria and dysphagia. The weakness and fatigue worsen on exertion and improve with rest. Respiratory muscle and limb weakness are rare at the onset of the disease. For the past two decades, there has been considerable progress in understanding the diagnosis and management of myasthenia gravis. The diagnosis is based on clinical presentation, neurologic examination, and confirmation by means of electrophysiologic testing and immunologic studies. Myasthenia gravis mimics many neuromuscular diseases and even illnesses such as depression and chronic fatigue syndrome. One should always exclude drug-induced myasthenia gravis for all patients. With the introduction of new modalities of treatment, particularly immunosuppressive or immunomodulating drugs, plasma exchange and thymectomy, the morbidity and mortality of myasthenia gravis have decreased dramatically to the point that myasthenia gravis should not be considered as serious a disease as it once was. Although the several therapeutic options are usually effective and have meant independence in daily life to many patients with myasthenia gravis, well-designed, controlled, prospective studies are still lacking.

A 55-years-old woman had left neck pain and headache, dizziness, left Horner's sign, left abducens palsy, diplopia, left peripheral facial palsy, left loss of hearing, left tinnitus, left paralysis of vocal cord and soft palate, dysphagia, left limb ataxia, truncal ataxia, disturbance of temperature and pain sensation over Th10 on the right involving the right face. Left vertebral angiography revealed tapering occlusion of the left vertebral artery. Right vertebral angiography showed normal angiogram of the basilar artery and bilateral anterior inferior cerebellar arteries. MRI disclosed infarcts in the left lateral inferior pons, left lateral medulla, and cerebellum of territories in the anterior inferior cerebellar artery and posterior inferior cerebellar artery. T2 weighted image showed septum (intimal flap) in the left vertebral artery. This is the very rare case of lateral inferior pontine syndrome and lateral medullary syndrome due to the vertebral artery dissection.

We report a case of large cystic acoustic neurinoma. A 52-year-old male was admitted to hospital with a history of progressive dysphagia, gait disturbance and diplopia for 2 months. On admission, neurological examinations revealed Bruns' type nystagmus to the left side, hypesthesia in the distribution of the second and third divisions of the left trigeminal nerve, and partial paresis of cranial nerves IX, X, and XII on the left side, and truncal ataxia. A pure-tone threshold audiogram indicated the presence of 32 dB hearing loss in the left ear. Speech discrimination was 80%. Caloric vestibular responses were absent on the left side. Skull radiographs with polytomographs of the internal auditory canal (IAC) were normal. Bony changes in the IAC were not found by high-resolution bone-window computed tomography (CT) scan. A plain CT scan revealed a large low-attenuated cystic mass in the left cerebellopontine angle (CPA), which was associated with displacement of the fourth ventricle. An enhanced CT scan demonstrated a thin rim-enhancement in the cyst wall. Magnetic resonance imaging (MRI) scans disclosed a large rim-enhanced cystic mass extending superiorly into the tentorial incisura and inferiorly into the foramen magnum. At surgery via a left suboccipital approach, a large cystic mass was found at the left CPA arising from the VIIIth nerve, and compressing the Vth, VIth, VIIth and lower cranial nerves. The cyst was filled with a xanthochromic fluid and was firmly attached to the internal auditory meatus (IAM). However no tumor extension into the IAM was confirmed. The tumor was excised completely. The postoperative course was uneventful, except for impairment of the VIIth and VIIIth nerves. At 6 months after the first operation, the facial nerve had improved up to grade III (Hause-Brackmann stage). Histological examinations revealed a typical benign acoustic neurinoma with predominant representation of Antoni B tissues. The cyst wall contained numerous abnormal sinusoid and telangiectasia-like vessels which showed occasional thromboses. The vessel walls displayed endothelial proliferations and were frequently hyalinized. Hemosiderin deposits and hemosiderin-containing phagocytes were also found near these vessels. Myxoid degeneration and necrosis were evident in vast areas. These degenerative changes appeared to be the principal causes of the large cystic formation. 16 cases including our case have been reported. The broad characteristics of the clinical symptoms and radiological findings of these tumors are discussed.

The incidence of wound botulism is increasing and the epidemiology of the disease is changing. The majority of new cases are associated with injection drug use, in particular, the use of Mexican black tar heroin. This case report and discussion of wound botulism illustrate the following important points: Dysphagia, dysphonia, diplopia, and descending paralysis, in association with injection drug use, should alert the treating physician to the possibility of wound botulism. In such patients, the onset of respiratory failure may be sudden and without clinically obvious signs of respiratory weakness. For the reported patient, maximum inspiratory force measurements were the only reliable indicator of respiratory muscle weakness. This is a measurement not routinely performed in the ED, but may prove essential for patients with suspected wound botulism. To minimize the effect of the botulinum toxin and to decrease length of hospital stay, antitoxin administration and surgical wound debridement should be performed early.

Here we present a 53-year-old woman with rheumatoid pachymeningitis. The subject had rheumatoid arthritis (RA) for 15 years. In April, 1996 she began to experience intermittent headaches. In September, her headaches became severe and continuous. In October, she suddenly developed ptosis of the left eye and diplopia. She also started to have dysphagia and she found it increasingly difficult to eat. She was admitted to our hospital on November 1, 1996. Neurological examinations revealed palsies of the left IIIrd, IVth, and VIth, and bilateral IXth, and Xth cranial nerves. Laboratory findings showed leukocytosis, elevated blood sedimentation rate, and positive CRP. Serum RA titer was positive (30x). The cerebrospinal fluid was normal and bacteriological examination was negative. T1-weighted MRI demonstrated hypertrophic cranial dura extending from the falx cerebri to tentorium cerebelli, which was enhanced markedly by Gd-DTPA. The dura adjacent to the cavernous sinus and the clivus were also thickened, which probably caused her cranial polyneuropathies. The dural biopsy showed massive infiltration of the inflammatory cells throughout the dura, proliferation of collagen fibers, and necrotic granuloma with neutrophilic infiltrations. Neither rheumatoid nodules, nor vasculitis were found. Despite the absence of rheumatoid nodules in the dural biopsy, the clinical features, pathologic specimens, and MRI findings of the thickened dura were most consistent with rheumatoid pachymeningitis. Administration of dexamethason ameliorated her headache on the 4th hospital day, and the cranial polyneuropathies completely disappeared on the 35th hospital day. The dural enhancement previously seen on the contrast T1-weighted MRI was diminished. Serum RA titer was also normalized (10x). Rheumatoid pachymeningitis is an extremely rare disease, and only 16 cases were reported in the literatures. Hypertrophic pachymeningitis should be considered as a diagnostic possibility in RA patients who have prolonged headache, and Gd-DTPA MRI is recommended to demonstrate the dural involvement.

Forty-one patients suffering from autosomal dominant cerebellar ataxia type I (ADCA-I) were subjected to a genotype-phenotype correlation analysis using molecular genetic assignment to the spinocerebellar ataxia type 1, 2 or 3 (SCA1, -2 or -3) genetic locus, clinical examination and nerve conduction as well as evoked potential studies. Pyramidal tract signs, pale discs, and dysphagia were more frequent in SCA1 compared with SCA2 and SCA3 patients, while double vision occurred less frequently. Visual evoked potentials and motor evoked potentials following transcranial magnetic stimulation were abnormal in almost all SCA1 patients, but only in a minority of SCA2 and SCA3 patients. In contrast, somatosensory evoked potentials were delayed or absent in the majority of patients with no significant differences between the mutations. Abnormalities of brainstem auditory evoked potentials were found in about half of the patients irrespective of the underlying mutation. In addition, reduced sensory nerve action potentials, suggesting sensory axonal neuropathy were found in all three mutations. These findings provide electrophysiological evidence that pyramidal and visual pathways are differentially affected in SCA1, SCA2 and SCA3 patients.

Botulism is a rare disease which usually is caused by preformed botulinum toxin in food. However, this article describes a case of wound botulism in a 29-year-old male heroin addict who developed progressive diplopia, dysphagia and proximal weakness of skeletal limb muscles. He needed mechanical ventilation for two weeks. The clinical diagnosis of botulism was supported by neurophysiological tests. Assays for detection of botulinum toxin and Clostridium botulinum were negative. The patient had not eaten any contaminated food the last two weeks before symptoms appeared, but he had multiple contaminated skin wounds. After treatment with botulinum antitoxins and antibiotics he gradually recovered, and six weeks later he was discharged from hospital in good condition. To the best of our knowledge this is the first case of wound botulism reported in Norway.

A 61-year-old woman in excellent health and taking no medications presented with progressive dyspnea on exertion. She did not exhibit diplopia, dysphagia, dysarthria or muscle weakness. Her condition deteriorated, and respiratory distress developed. The patient was intubated and placed on mechanical ventilation. A computed tomogram of her chest revealed a moderately enlarged thymus gland unsuspected on a plain x-ray film. Myasthenia gravis was diagnosed on the basis of a high acetylcholine receptor antibody titer. Treatment started with prednisolone, anticholinesterase agent, and plasma exchange. The patient underwent a thymectomy 3 weeks after her diagnosis. Her symptoms were brought under control by anticholinesterase agent and prednisolone. This case illustrates the need to consider myasthenia gravis as well as other motor-neuron disorders when evaluating individuals presenting acute respiratory failure of unknown origin.

We have retrospectively analysed the records of patients diagnosed as having myasthenia gravis and followed up in our department from February 1973 to March 1995. The main clinical findings were ptosis, diplopia, dysphagia, dysphonia or dysarthria, mastigatory impairment, dyspnea, asthenia, weakness of the cervical muscles and of the extremities, as well as findings of the physical and neurological examination. Based on the information collected, the patients were classified clinically according the modified Osserman-Gerkins scale, but considering the non-dynamic aspects of that scale, we used the modified functional scale of Niakan and classified the patients clinically as follows: remission, controlled, stable, partially controlled, poorly controlled, no response. We collected 153 patients, 104 (68.0%) females and 49 (32.0%) males producing a female/male ratio of 2.2:1. The duration of the disease varied from seven days to 27 years, mean 6.26 years (+/- 5.44). Age at the first symptoms varied between 24 hours to 80 years, mean of 32.13 years (+/- 19.48). We had 30 patients ranging from 0 to 15 years of age, 91 patients were observed between 15 and 50 years and 32 patients after the age of 50 years. Above the age of 60 years, the disease aflicts males more than females with a ratio of 1.5:1. The acquired autoimmune form with generalized weakness was the most frequent presentation. However, ocular muscle weakness with ptosis and diplopia were the most common clinical presentation in our series.
