The medical records of 54 dogs presented to the Hebrew University Veterinary Teaching Hospital and diagnosed with heat stroke were retrospectively reviewed. Data abstracted included history, clinical and clinicopathological signs at admission, treatment, disease progression, and outcome. Exertional and environmental heat stroke were present in 63% (34 of 54) and 37% (20 of 54) of the dogs, respectively, and 78% (42 of 54) were examined between June and August. The mean temperature and heat discomfort index in the particular days of heat stroke were significantly increased (P < .001, P < .001, respectively) compared with their corresponding average daily values. In 27 dogs the body temperature was > or = 41 degrees C (105.8 degrees F). Belgian Malinois (15%, odds ratio [OR] = 24, 95% confidence interval [CI95%] 8.2-64.5), Golden and Labrador Retrievers (21%, OR = 2.08, CI95% 0.95-4.2), and brachycephalic breeds (25%, OR = 1.7, CI95%], 0.81-3.21) were overrepresented, whereas small breeds (<8 kg) were underrepresented (2%, OR = 0.08, CI95%, 0.002-0.48). Thrombocytopenia (45 of 54 dogs) and prolongation of the prothrombin (PT) and activated thromboplastin (aPTT) times (27 of 47 dogs) were recorded during hospitalization. Disseminated intravascular coagulation (P = .013) and acute renal failure (P = .008), diagnosed in 28 of 54 and 18 of 54 of the cases, respectively, were risk factors for death. The overall mortality rate was 50%. Hypoglycemia (<47 mg/dL, P = .003), prolonged PT (>18 seconds, P = .05), and aPTT (>30 sec, P < .001) at admission were associated with death. Serum creatinine >1.5 mg/dL (P = .003) after 24 hours, delayed admission (>90 minutes, P = .032), seizures (P = .02), and obesity (P = .04) were also risk factors for death. Heat stroke in dogs results in serious complications and high fatality rate despite appropriate treatment.

A case report of seizure due to photic stimulation from sunlight shining through spinning helicopter rotor blades is discussed. A review of photosensitive epilepsy is provided with particular emphasis on the effects and frequencies of photic stimulation required to induce symptoms. The frequencies of flashing light produced by spinning helicopter rotor blades commonly used in air medical transport range from 24 to 27 flashes per second. These frequencies are well within the range reported in the literature to produce symptoms in the laboratory setting. The literature provides only a few case reports of individuals sustaining a seizure after photic stimulation from spinning turboprop or helicopter blades. Symptoms range from mild discomfort and headache to profound spatial disorientation and seizures and may be an underrecognized but preventable complication of air medical transport.

In order to investigate the safety of rapidly infused intravenous valproate in children with seizures, the drug was administered to 18 patients (age range, 1-16 years) at doses ranging from 7.5 to 41.5 mg/kg and rates of 1.5 to 11 mg/kg per minute. Forty-eight intravenous valproate doses were administered during 19 hospital admissions (range, 1-16 doses per admission). Only one adverse event was reported; a 9-year-old male experienced burning at the infusion site while receiving 660 mg intravenous valproate at 6 mg/kg per minute. The patient tolerated three subsequent infusions (one of 330 mg and two of 165 mg) at the same rate with no further discomfort. Electrocardiogram results, available for 18 admissions, revealed no arrhythmias, bradycardias, or hypotensive episodes. No abnormal laboratory results were reported. Rapid intravenous valproate infusion appears to be safe in pediatric patients.

In most circumstances, first aid for seizures aims to protect the individual from harm during a seizure. Many people harbor misconceptions about or simply do not know how to respond to a seizure. Guidelines for seizure first aid from the Epilepsy Foundation are readily available and widely distributed, yet data from surveys and studies illustrate a deep unmet need in seizure first aid education. Lack of knowledge increases the potential for inappropriate or inadequate responses by parents, teachers, coworkers, and the public at large to repetitive or prolonged seizures, and the associated discomfort about how to provide first aid also can contribute to the general stigma associated with epilepsy. Clinicians play a key role in educating patients, parents, caregivers, and the community about how to respond to an individual who is having a seizure. This article reviews the data regarding seizure first aid knowledge among the various groups that may be called on to respond to a repetitive or prolonged seizure, highlights important goals of seizure first aid (including the prevention of status epilepticus) that should be relayed to these groups, and discusses the positive impact of seizure first aid education.

A 66-year-old woman was admitted to our hospital because of vomiting and appetite loss. For the 2 days prior to admission, she had a cold, which had developed into acute viral bronchitis on admission. Because laboratory data on admission showed hyponatremia, intravenous infusion of Ringer's lactate solution was started. However, generalized seizures appeared, and she developed a coma on the day of admission. Her plasma antidiuretic hormone (ADH) level was high in the context of a low serum osmolality on the second hospital day. The infusion rate was increased, and the patient's consciousness level returned to normal. However, her normalized serum Na level declined again as she drank much water to reduce throat discomfort. As the throat discomfort caused by the throat inflammation improved with azulene gargling, her water intake was reduced, and the serum Na concentration returned to normal. Thus, polydipsia caused by a throat inflammation partially contributed to hyponatremia in this patient. We note that increased ADH secretion has been reported in adults with acute respiratory infection. Therefore, we concluded that polydipsia caused by the throat inflammation, plus increased ADH secretion, resulted in hyponatremia in this patient. We should pay attention to the behavior of drinking extra fluid in patients with acute respiratory infections.

It has been well known for a number of years that abrupt withdrawal from alcohol following chronic use is associated with adverse consequences, ranging from mild tremors to withdrawal seizures. The overall purposes of treating alcohol withdrawal (AW) are to relieve patient discomfort, to prevent the development of more serious withdrawal symptoms, and to initiate long-term alcohol rehabilitation. Several areas of controversy exist in the clinical management of AW, including the optimal treatment setting, the need for pharmacologic management, and the most appropriate agent to prescribe when medication is deemed necessary. This article reviews the clinical features, general management, and treatment of AW.

A comparative analysis of treatment with keppra and topamax of various types of epilepsy has been carried out in 37 patients aged from 1 to 35 years. Symptomatic temporal-frontal-lobe epilepsy was diagnosed in 22 patients, symptomatic temporal lobe epilepsy in 15 including "urgent aid" cases with previous antiepileptic therapy being ineffective. Effect of the drugs on the cerebral blood flow was studied with the single proton emission CT. Keppra treatment was assigned to 20 patients in dosages varying from 500 to 2,500 mg (30-50 mg/kg/daily) for single intake. Then the patients received the drug two times daily under the clinical and EEG control. The drug was tested for using in the "urgent care mode". The clinical effect by 43% decreasing (p<0,001) of seizures was observed in the first 12 h. The "stability state" was 80% after 8 months of the treatment. Topamax was administered to 17 patients in two dosages depending on patient's age and weight starting with 25-50 mg (from 3 to 12,5 mg/kg/daily) with the dose adjustment during 2 days. The latter was depended on the dynamics of clinical data and EEG. For the first 2 days, patients revealed changes in seizures quality: the seizure structure became less complex, without generalized seizures, and period of a seizure was shorter. Reduction of seizures frequency was observed on the 7-10th day and made up on average 73,9% (p<0,01). Comparing to keppra, topamax did not cause signs of autonomic and psychological discomfort. Generalized seizures became less frequent by the 3rd day.

Intraoperative brain mapping has the goal of aiding with maximal surgical resection of brain tumors while minimizing functional sequelae. Retrospective randomized studies on large populations have shown that this technique can optimize the surgical approach while reducing postoperative morbidity. During direct electrical stimulation of the language areas adjacent to the tumor, the patient should be collaborative and be able to speak to participate in language testing. Different anesthesiological protocols have been proposed to allow intraoperative brain mapping, which range from local anesthesia to conscious sedation or general anesthesia, with or without airway instrumentation. The most common intraoperative complications are seizure, respiratory depression, and patients' stress and discomfort. Since awake craniotomy carries both benefits and potential risks, the following factors are crucial in the management of patients: 1) careful selection of the patients and 2) communication between the anesthesiological and surgical teams. To date, there remains no consensus about the optimal anesthesiological regimen to use. Only prospective, multicentre randomized studies focused on evaluating the role of different anesthesiological techniques on intraoperative monitoring, postoperative deficits, and intraoperative complications can answer the question of which anesthesiological approach should be chosen when intraoperative brain mapping is requested.

The ratings of discomfort from a wide variety of images can be predicted from the energy at different spatial scales in the image, as measured by the Fourier amplitude spectrum of the luminance. Whereas comfortable images show the regression of Fourier amplitude against spatial frequency common in natural scenes, uncomfortable images show a regression with disproportionately greater amplitude at spatial frequencies within two octaves of 3 cycles deg(-1). In six studies, the amplitude in this spatial frequency range relative to that elsewhere in the spectrum explains variance in judgments of discomfort from art, from images constructed from filtered noise, and from art in which the phase or amplitude spectra have been altered. Striped patterns with spatial frequency within the above range are known to be uncomfortable and capable of provoking headaches and seizures in susceptible persons. The present findings show for the first time that, even in more complex images, the energy in this spatial-frequency range is associated with aversion. We propose a simple measurement that can predict aversion to those works of art that have reached the national media because of negative public reaction.

Many electronic games have violent contents. A growing population of adolescent boys and girls report to regularly play violent electronic games (VEGs). Extensive video game use has been linked with obesity, physical discomfort and seizures. We report on a young, healthy man who participated in an online VEG and developed a life threatening stress-induced cardiomyopathy (SICMP) with ventricular tachyarrhythmia and apical thrombus.
