Many children in Japan developed various neuropsychological problems, including seizures, while watching the program Pocket Monster, televised on 16 December 1997. To examine the basis for this incident, we have performed a survey of volunteering children and their parents who visited our pediatric clinics for other reasons from 8 January to 28 February 1998. Children and their parents filled out questionnaires. Among the total of 662 children surveyed, the great majority (603, 91.1%) was found to have watched the Pocket Monster program and 30 individuals (5.0% of viewers) complained of variable degrees of neuropsychological abnormalities. These included seizures (two cases), headache (nine cases), nausea (eight cases), blurred vision (four cases), vertigo (two cases), dysthymia (two cases) and vomiting (one case). Nearly half (14) of these children developed symptoms during or immediately after watching the program, while the remainder did so later. Representative cases are reported and other statistical aspects are discussed.

Vertigo has long been recognized by the clinician as a frequent accompanying symptom of the adult migraine syndrome. This association has not been so readily identified in the pediatric population, and, as a consequence, children undergo unnecessary evaluations. We reviewed the charts of all children and adolescents referred for vestibular function testing to the Balance Center at the Barrow Neurological Institute between July 1994 and July 2000 (N = 31). Items analyzed included age, gender, symptoms that prompted the referral, test outcomes, family medical history, and final diagnosis. The most common justification for vestibular testing referral was the combination of dizziness and headache. Other less common reasons were "passing out" episodes, poor balance, and blurred vision. Normal test results were obtained from 70% of patients (n = 22). The most common abnormal test outcome was unilateral vestibular dysfunction (n = 5). Bilateral peripheral vestibular dysfunction was present in three patients. One patient had central vestibular dysfunction. The final diagnoses were vestibular migraine (n = 11), benign paroxysmal vertigo of childhood (n = 6), anxiety attacks (n = 3), Meniere's disease (n = 2), idiopathic sudden-onset sensorineural hearing loss (n = 1), vertigo not otherwise specified (n = 1), familial vertigo/ataxia syndrome (n = 1), and malingering (n = 1); in five patients, no definitive diagnosis was established. The stereotypical patient with vestibular migraine was a teenage female with repeated episodes of headache and dizziness, a past history of carsickness, a family history of migraine, and a normal neurologic examination. Patients who fit this profile are likely to have migrainous vertigo. Consequently, a trial of prophylactic migraine medication should be considered for both diagnostic and therapeutic purposes. Brain imaging and other tests are appropriate for patients whose symptoms deviate from this profile.

Intracranial hypotension syndrome as a complication of diagnostic lumbar puncture is a rarely observed entity. Intracranial hypotension syndrome is characterized by postural headache, neck pain/stiffness, blurred vision, nausea, vomiting, clouding of consciousness, dizziness and vertigo. The majority of cases resolve spontaneously with conservative treatment. Rarely, epidural blood patch is required. We report a 41-year-old man with multiple sclerosis, who developed intracranial hypotension syndrome after diagnostic lumbar puncture and who did not respond to conservative treatment. A subdural hematoma was subsequently found, when the patient showed considerable worsening of clinical conditions with life-threatening symptoms. Surgical evacuation of the subdural hematoma was not sufficient to improve significantly the patient's conditions, while complete symptoms remission was achieved 12 hours after epidural blood patch. We stress the need for epidural blood patch in any case of post-diagnostic lumbar puncture postural headache which does not resolve with conservative therapy.

1. The two major classifications of stroke are ischemic and hemorrhagic. Ischemic strokes account for 75% of all strokes and result from the complete occlusion of an artery. Hemorrhagic strokes, often caused by aneurysm or hypertension, are caused by the rupture of a cerebral blood vessel and bleeding into the surrounding tissue. 2. The signs and symptoms of stroke may include unilateral weakness or paralysis, a sagging of one side of the face, double or blurred vision, vertigo, numbness or tingling, and language disturbances. 3. Management of ischemic stroke may include thrombolytic agents (e.g., heparin, warfarin) if the individual is treated within 6 hours after the onset of symptoms. Diagnostic tests may include, computed tomography scan, transesophageal echocardiagraphy, Doppler ultrasonography, and electrocordiography. 4. Occupational health nurses can be actively involved in helping workers modify their risks for stroke, developing and implementing an action plan if an individual is experiencing a stroke, and facilitating the individual's reentry into the worksite after rehabilitation is completed.

Manual medicine aims at diagnosing and treating different disorders of the musculoskeletal system. It is a multidisciplinary approach with special emphasis on reversible disorders of the joints, muscles and ligaments. This treatment conception includes chirotherapy, physical therapy and drug treatment. The spine, an in particular the cervical spine, is treated primarily for joint disorders characterized by a variety of symptoms (e.g.headache, vertigo, dizziness, blurred vision). Manual medicine should be an integral part of modern clinical otolaryngology.

Neurovestibular symptoms experienced by astronauts in the post-flight period were examined using data from medical debriefs contained in the NASA Longitudinal Study of Astronaut Health database. Ten symptoms were identified (clumsiness, difficulty concentrating, persisting sensation aftereffects, nausea, vomiting, vertigo while walking, vertigo while standing, difficulty walking a straight line, blurred vision, and dry heaves), of which eight were crossed with twelve demographic parameters (mission duration, astronaut gender, age, one-g piloting experience, previous space flight experience, g-suit inflation, g-suit deflation, in-flight space motion sickness, in-flight exercise, post-flight exercise, mission role, fluid loading). Three symptoms were experienced by a majority of subjects, and another two by more than a quarter of the subjects. Intensity of the symptoms was mild, suggesting that they are unlikely to pose a risk to the crew during landing and the post-flight period. Seven of the symptoms and eight of the parameters under study were found to be significantly associated with each other.

The only venomous reptile that naturally occurs in Poland is the adder or common viper (Vipera berus). Its bites are not of great epidemiological importance, but in some cases serious life-threatening symptoms may appear. The most common symptoms of adder envenomation are: local edema, reddening and pain of the bitten site and also the general symptoms coming from the alimentary tract (vomiting, diarrhoea, abdominal pain), the circulatory system (hypotension, shock, ECG abnormalities), the central nervous system (sleepiness, vertigo, disorientation, loss of consciousness), hematological symptoms (leukocytosis, hemolysis, coagulopathy) and allergic symptoms (fever, urticaria, angio-oedema). In the present study we described the case of a twenty-year-old patient hospitalized at the Toxicology Department of the Collegium Medicum UJ after a viper bite. Except for some above-mentioned symptoms he also developed ocular symptoms like ptosis and blurred vision. Such symptoms after the common viper bite have not been described in the literature till now. The cause of them seems to be an intense allergic reaction in the region of the orbit and eyelids all the more so because the patient had the positive allergy history. However, taking into account the latest reports from the literature, a neurotoxic action of some components of the Vipera berus venom may also play a role. Because of the developing general symptoms a specific equine antivenom was administered to the patient, apart from the supportive care, without any serious side effects that usually are observed after the use of such a kind of sera. It is thought that the sheep antivenom is better than the equine one considering a lack of allergic side effects. As a result of applied treatment the local and general symptoms including ocular symptoms subsided.

The problem of health effects of electromagnetic fields (EMF) emitted by cellular phone base stations evokes much interest in view of the fact that people living in their vicinity are fated to continuous exposure to EMF. None of the studies carried out throughout the world have revealed excessive values of standards adopted by the International Commission on Non-Ionizing Radiation Protection (ICNIRP). A questionnaire was used as a study tool. The results of the questionnaire survey reveal that people living in the vicinity of base stations report various complaints mostly of the circulatory system, but also of sleep disturbances, irritability, depression, blurred vision, concentration difficulties, nausea, lack of appetite, headache and vertigo. The performed studies showed the relationship between the incidence of individual symptoms, the level of exposure, and the distance between a residential area and a base station. This association was observed in both groups of persons, those who linked their complaints with the presence of the base station and those who did not notice such a relation. Further studies, clinical and those based on questionnaires, are needed to explain the background of reported complaints.

The authors describe the case of a 27-year-old man who was examined on account of vertigo and blurred vision. In the objective case-history there was mild confusion, in the physical examination broad symmetrical mydriasis dominated. Later other similar patients were found. Atropine intoxication was proved. The source of the alkaloid was poppy seed contaminated with seeds of henbane (Hyoscyamus niger), in bakery goods served in the works canteen.

A 34-year-old man had a history of short-lasting episodes of rotatory vertigo followed by severe headache, provoked by sudden movements of the head and body. MRI of the brain revealed hydrocephalus secondary to a colloid cyst at the level of the foramen of Monro. The patient underwent microsurgery, after which he remained without symptoms. Colloid cysts are rare, benign tumours accounting for 0.5-1.0% of all primary brain tumours. They are attached by a stalklike appendage to the roof of the third ventricle between the fornices. Typical symptoms include intermittent headache, vomiting, occasional dizziness and blurred vision. These symptoms may be secondary to intermittent obstruction of cerebrospinal-fluid outflow through the foramen of Monro. The results of clinical and neurological examination are usually normal. In any patient with short-lasting episodes of severe headache, provoked by changes in position, an MRI of the brain should be done to exclude a colloid cyst. In general, these patients do not fulfil the criteria of the International Headache Society for migraine because of the short-lasting nature of the pain.
