Journal of the Korean Medical Association 2002;45(2):176-190
Distinguishing epileptic seizure from non-epileptic seizure is a common diagnostic problem. Neurogenic or cardiac syncope can appear similar to atonic and even convulsive seizures. Classic migraine and transient ischemic attacks may also resemble epileptic seizures. Sleep disorders including REM sleep behavior disorder, nocturnal paroxysmal dystonia, and narcolepsy likewise simulate an epileptic seizure. Movement disorders such as paroxysmal dyskinesia can be misinterpreted as epileptic seizures (reflex epilepsy or myoclonic seizures). Psychogenic seizures are often misdiagnosed as an intractable epilepsy. Prior to the definitive diagnosis of epilepsy, possible non-epileptic seizures should be excluded. For the correct decision, a thorough and systematic history taking is important. In addition, EEG, pseudoseizure induction test, head-up tilt test, EKG, sleep studies, and video-EEG monitoring may be necessary. Misdiagnosis of non-epileptic seizures as epilepsy may result in unnecessary anti-epileptic drug use. At the same time, we should let the patients understand what the epilepsy is and that epilepsy is a treatable disease.

Death by drowning is a major cause of unnatural death worldwide. It is therefore important to conduct forensic examination of immersed bodies following drowning, in order to determine the diagnosis of drowning, because no specific methods have been established thus far. Therefore, we performed a series of rat experiments to compare autopsy findings between seawater and fresh water drowning cases, which included the presence of pleural effusion and histologic findings of the lung. The results showed that the volume of pleural effusion increased in the seawater drowning group compared to the fresh water drowning group, and the total weight of lung was affected by the type of drowning medium and postmortem interval. However, histologic findings of the lung showed no significant difference between the 2 types of drowning mediums.

The purpose of this study was to investigate what the intermediate filaments in the cells of rat mandibular fossa fibrous layer are and any relationships between the presence of these filaments and aging. Mandibular fossae of 4 groups of rats(14-day, 28-day, 55-day and adult groups) were removed on bloc and processed for immunostaining and were subjected to light microscopic examination. The results were as follows : In 14-day group, there were no immunoreactive cells in fibrous layer of mandibular condyle articular surface. But in 28-day group, many immunoreactive cells were seen in fibrous layer, especially central portion of articular surface of mandibular fossa. These cells were fusiform shaped and immunoreactivities were seen in the cytoplasm around the nucleus. In 55-day group many immunoreactive cells were seen in fibrous layer of mandibular fossa. These cells were fusiform shaped and distributed evenly in central portion of this fibrous layer. Immunoreactivities were seen in the cytoplasm around the nucleus. In adult group, the results were similar to 55-day group, Many immunoreactive cells were seen in fibrous layer of mandibular fossa especially central portion. According to these results, vimentin immunoreactive filaments appear with aging and increment of mechanical load associated with incision or mastication.

We performed case-control studies for the 1, 138 Korean adult men. According to the results of UGIS, we classified the gastritis into the erosive gastritis, superficial gastritis, and hypertrophic gastritis. And then, we selected controls among non-gastritis group after matching. Alcohol intake and smoking history was obtained by questionnaire. And we observed the effects of alcohol intake and smoking to the each gastritis. The results obtained were as follows; 1. Smokers had a risk of getting erosive gastritis more than twice (2.6) than non-smokers and there was dose-response relationships between smoking and erosive gastritis. Alcohol intake, however, had no significant relation with the erosive gastritis. 2. Both smoking and alcohol intake had no significant relations with superficial gastritis. 3. Smoking had no significant relation with hypertrophic gastritis, but dividing between those who drank more than 100gm of alcohol a week and those who drank less, we obtained the odds ratio of 3. 4 suggesting that there existed a significant relation between moderate or excessive alcohol intake and hypertrophic gastritis. 4. Among the gastritis patients, those who had erosive gastritis smoked most heavily, and those who had hypertrophic gastritis drank most excessively.

PURPOSE: The ictal perfusion patterns of cerebellum and basal ganglia have not been systematically investigated in patients with temporal lobe epilepsy (TLE). Their ictal perfusion patterns were analyzed in relation with temporal lobe and frontal lobe hyperperfusion during TLE seizures using SPECT subtraction. MATERIALS AND METHODS: Thirty-three TLE patients had interictal and ictal SPECT, video-EEG monitoring, SPGR MRI, and SPECT subtraction with MRI co-registration. RESULTS: The vermian cerebellar hyperperfusion (CH) was observed in 26 patients (78.8%) and hemispheric CH in 25 (75.8%). Compared to the side of epileptogenic temporal lobe, there were seven ipsilateral hemispheric CH (28.0%), fifteen contralateral hemispheric CH (60.0%) and three bilateral hemispheric CH (12.0%). CH was more frequently observed in patients with additional frontal hyperperfusion (14/15, 93.3%) than in patients without frontal hyperperfusion (11/18, 61.1%). The basal ganglia hyperperfusion (BGH) was seen in 11 of the 15 patients with frontotemporal hyperperfusion (73.3%) and 11 of the 18 with temporal hyperperfusion only (61.1%). In 17 patients with unilateral BGH, contralateral CH to the BGH was observed in 14 (82.5%) and ipsilateral CH to BGH in 2 (11.8%) and bilateral CH in 1 (5.9%). CONCLUSION: The cerebellar hyperperfusion and basal ganglia hyperperfusion during seizures of TLE can be contralateral, ipsilateral or bilateral to the seizure focus. The presence of additional frontal or basal ganglia hyperperfusion was more frequently associated with contralateral hemispheric CH to their sides. However, temporal lobe hyperperfusion appears to be related with both ipsilateral and contralateral hemispheric CH.

OBJECTIVE: To evaluate the basophil histamine releasability in response to IgE- and non- IgE-mediated stimuli in children with atopic asthma. Met: Basophil histamine releasability was measured in Dermatophagoides farinae (D. farinae)-sensitive atopic asthmatics, D.farinae-sensitive healthy atopics, non-atopic asthmatics, and healthy non-atopics. Basophils were stimulated with D.farinae, goat antihuman IgE antibody, formyl-Met-Leu-Phe(fMLP), and Calcium ionophore A23187. Histamine was measured by automated fluorometric technique. RESULTS: Sponianeous histamine release was higher in atopic asthmatics compared to healthy non-atopics. Histamine release by D.farinae and by anti-IgE antibody was higher in atopic asthmatics compared to the other groups. There was no difference in histamine release by fMLP among all groups. Histamine release by Calcium ionophore was higher in healthy atopics and non-atopic asthmatics compared to healthy non-atopics. The atopics showed correlation between histamine release by D.farinae, by anti-IgE antibody and total serum IgE levels. CONCLUSIONS: Spontaneous and IgE-mediated histamine release were related to the presence of both atopy and asthma, whereas non-IgE mediated histamine release was different depending on the stimuli.
