In a clinical trial the efficacy of encainide, a newly developed class I antiarrhythmic agent, was compared with the well-known mexiletine. Nine patients with different underlying cardiac disease and chronic complex ventricular ectopies (documented by 24-h Holter monitoring, confirmed during the initial placebo period) entered the study. The dosage of encainide was increased from 25 to 75 mg three times daily and the antiarrhythmic effect monitored by repeated 24-h Holter registration and in some patients by treadmill exercise testing. During the clinical followup we noted a high incidence of so-called "minor side effects" (headache, dizziness, blurred vision, tremor, and nausea), which caused us to terminate the study. In all instances adverse effects emerged before ectopic activity was suppressed satisfactorily prohibiting further increment of dosage. These results indicate that encainide cannot be regarded as an antiarrhythmic drug of first choice in routine clinical application.

We treated four patients with corneal burns resulting from mishaps while using electric curling irons. In all cases, the burns were symptomatic with blurred vision, tearing, pain, and photophobia. Injury was limited to the corneal epithelium, and management included debridement, topical antibiotics, cycloplegia, and pressure patching. Burns resolved completely within 48 hours after debridement and patching.

Stimuli on corresponding points of both retinae that cannot be fused may cause binocular rivalry: the stimuli suppress each other alternately. This effect was used to study the influence of image sharpness upon binocular inhibition. Blurring an image means decreasing its contrast and attenuating its high spatial frequencies. Both factors diminish the time that a stimulus is perceived during rivalry. This fact has implications both for normal vision--as objects off the horopter are normally blurred--and for disturbed vision when the image of one or both eyes is (locally) deteriorated. In both cases, the binocular field of view can be combined from the 'good' parts of both eyes. Hence, the field of view may consist, in a piece-meal fashion, of parts stemming from the right or the left eye exclusively and others where both images are superimposed. We present evidence for the hypothesis that there is a common neural mechanism causing both binocular rivalry and functional amblyopia in anisometropia and strabismus. Consequences of the results on rivalry suppression for the pathophysiology and therapy of strabismic amblyopia are discussed.

A 44-year-old farmer complained blurred vision and disturbance of recent memory. During his driving car traffic accident happened due to his right homonymous hemianopsia. On the 1st admission, neurological examination revealed choked disc(1 D.), hemianopsia, memory disturbance, dyscalculia, dyslexia and dysgraphia. The angiograms showed feeding arteries from left middle cerebral artery and posterior cerebral artery. Tumor vessels looked like cork-screw in the arterial phase and homogeneous tumor shadow was depicted in late venous phase. Contrast enhancement CT scan revealed a nodular homogeneous high dense lesion on the occipital region. Hemorrhage during every craniotomy was too much to remove and at last metastasized to left II rib and right VIII rib and right radius. Their histological examination reveals numerous endothelial-lined vascular channels and atypia of tumor cells with mitoses. Silver impregnation demonstrates networks of reticulum fibers surrounding the capillaries and tumor cells. Hemangiopericytoma in meninges forms entity and our case reports the WHO classification. Total removal should have to be done once for all by means of LASER (light amplification by stimulated emission of radiation).

The new selective serotonin (5-HT)-uptake inhibitor femoxetine was compared with amitriptyline in a double-blind clinical trial comprising 77 depressed patients. The depressive symptoms were evaluated with the Hamilton rating scale, and a global clinical evaluation. Both drugs showed an antidepressive effect and no significant differences were found. Femoxetine induced a significantly lower frequency of dry mouth and blurred vision; this difference is presumably due to the weak anticholinergic effect of this substance. A small but significant weight loss was observed in the femoxetine group but not in the amitriptyline group.

Daytime drowsiness and other sleep related symptoms such as attention and concentration difficulties, blurred vision and slurred speech were evaluated using seven point rating scales in 51 drug free depressed patients and an age and sex matched control group. Degrees of depression and anxiety were quantified using the Beck Depression Inventory and State Trait Anxiety Inventory respectively. Daytime drowsiness and sleep related symptoms were seen to be significantly higher in the index group. Both depression and anxiety scores significantly correlated with daytime drowsiness.

12 cases of food-borne botulism were registered in Sion, Switzerland, between 31 December, 1993 and 12 January, 1994. A type B toxin was isolated from the serum of one patient and from the incriminated ham. Clinical data of 10 male patients aged 21 to 54 years and some epidemiologic data are reported. The clinical course was mild to moderate with predominant autonomic and gastro-intestinal symptoms and signs: blurred vision (10 patients of 10), dry mouth with dysphagia (9/10), asthenia (7/10), diarrhea and/or constipation (7/10), nausea and vomiting (6/10), abdominal cramps (5/10), impaired sexual function (5/10), dilated pupils (4/10). Some discomfort (mainly blurred vision, asthenia and impaired sexual function) persisted for several months in most patients. Neuromuscular involvement was never the reason for seeking medical assistance and had often disappeared at the time of the first visit. Two patients were hospitalized, one for transient ileus of unknown origin and the second (first suspected case) for monitoring and infusion of trivalent equine botulinum antitoxin. This treatment was administered on day eight after intoxication and had no effect on this patient's outcome when compared with others. No patient died. Epidemiology, diagnosis, treatment and prognosis of botulism are discussed.

Multiple myeloma frequently affects the C.N.S with a high prevalence of spinal cord compression following vertebral neoplastic infiltration. On the other hand, solitary plasmacytomas, tumors that arise in a wide variety of locations due to the universal distribution of plasma cells, are infrequent within the cranial vault and rarely present as extramedullary lesions, arising from the intracranial soft tissues without affecting neighboring bony structures. Only 33 such cases have been reported in the medical literature. The authors report two additional cases of solitary intracranial, extramedullary plasmacytoma. Case 1.--54 year-old woman with a chief complaint of severe headache and behavioral changes of three months duration. C.N.S. imaging revealed a bifrontal mass lesion, arising from the anterior third of the falx cerebri. Case 2.--45 year old-man who complained of headache and blurred vision of a month duration C.N.S. imaging displayed a third ventricle mass lesion. In both cases the neuropathological diagnosis was extramedullary plasmacytoma. Postoperatively the confirmation of solitary intracranial plasmacytoma was achieved only after a thorough work-up to rule out the presence of neoplasm elsewhere in the body. Radiotherapy was given to both patients and follow-up has failed to reveal neoplastic disease 4 and 3 years, respectively, after the diagnosis.

Optic neuritis occurred in three of our patients receiving treatment with alpha interferon-2b (Intron-A; 3MU thrice weekly) for chronic hepatitis. The complication appeared within, 1, 9 1/2 and 10 months of treatment, respectively. In all cases, blurred vision was the initial complaint and subsequent electrophysiologic investigation confirmed the presence of optic tract neuropathy. The patients had no other neurologic signs. Computerized tomography and magnetic resonance image of the brain were not remarkable. Psychiatric symptoms, in the form of an interferon-associated depressive reaction, were present in two of them; in one case, it was severe enough to require immediate discontinuation of treatment. In two patients the visual symptoms resolved and the parameters of neurophysiologic testing returned to normal within 1 month after stopping interferon. In one case, however, residual optic tract impairment associated with a unilateral central scotoma and a substantial decrease of visual acuity was present 2 years later, despite a course of methylprednizolone. In this patient the interferon treatment was continued for 3 months despite the visual symptoms, and he later received two additional interferon courses because of relapses of hepatitis. We conclude that clinically evident optic tract neuropathy may complicate interferon administration. Candidates for interferon treatment may need routine examination of optic fields and visual evoked potentials, before and during administration of the drug to avoid possibly permanent visual sequelae.

Pterygium is known to cause corneal topographic changes that can result in decreased visual acuity. We present a case of recurrent pterygium causing blurred vision and diplopia, and document the corneal topographic changes, showing astigmatism of 15 diopters induced by lateral gaze, prior to surgical excision.
