Obtaining a complete and accurate history is one of the most crucial steps in the initial diagnosis and subsequent management of the poisoned patients. This information can then be integrated with physical evidence, clinical examination, laboratory and toxicological data in designing a therapeutic approach. Such information may include patient data, product information, and nature of exposure. The basic treatment for acute poisoning, whether of drug or chemical, is mainly symptomatic and supportive. The four cardinal principles of good management are ① identification of the causative drug or chemical as quickly as possible, ② evacuation of the poison from the stomach, except when contraindicated, ③ administration of an antidote if available, and ④ symptomatic and supportive therapy as indicated. Management in most cases of toxicity consists of supportive care, symptomatic treatment, and avoidance of exposure to the toxic material. In cases of life-threatening toxicity, maintenance of cardiopulmonary function and fluid and electrolyte balance are important. There are limited specific methods of treatment, or "antidotes". Use of oxygen counters the foxic effect and enhances the elimination of carbon monoxide. In cases acute cyanide of hydrogen sulfide poisoning, nitrites may be used to generate formation of cyanmethemoglobin or sulfmethemoglobin. Hydroxocobalamin can also be used as an antidote for cyanide. Atropine and pralidoxime can be life-saying in reversing the acute cholinesterase-inhibiting effects of organophosphate pesticides. Chelating agents may reverse acute toxicity caused by some metals.

This dental anthropological study was performed to analyse male and female students of Che-ju high school students. Cephalometric X-rays and dental casts were obtained of 60 male and 60 female students and the Mean and Standard Deviation were obtained. There was no difference in craniofacial morphology between male and female students but the size of craniofacial skeleton of the male is bigger than that of the female. The distance from NB line to pogonion is longer in the male group, and it meant that mandibular symphysis of the male is well developed than the female. The size of teeth of the male is larger than that of the female and is significant in upper and lower canine and first molar. The size of upper arch width, intercanine width, basal arch width and lower basal arch width of the male is larger than that of the female, but arch length of the male and the female showed no significant difference.

In order to compare the changes of dentofacial skeleton, teeth and soft tissue profile in Class I malocclusion patients treated with and without extraction, cephalometric radiographs were taken in 22 female patients as extraction group and 23 female as nonextraction group who were treated in the Department of Orthodontics in Chonnam National University Hospital. The results were as follows. 1. At the beginning of treatment, average age was 19.0 years in extraction group and 15.9 years in nonextraction group. Duration of treatment was 2.8 years in extraction group and 1.7 years in nonextraction group. 2. Before treatment, there were significant difference between 2 groups in the amount of protrusion and proclination in upper and lower central incisor and lower lip protrusion. After treatment, these differences were decreased. 3. In comparison before and after treatment in extraction group, upper and lower central incisor protrusion and lower lip protrusion were significantly improved. In nonextraction group, retrusion and improvement of inclination of upper and lower central incisor were not found.

Cholelithiasis is defined as the presence of stones within the lumen of the gallbladder or in the extrahepatic biliary tree. Cholecystitis, secondary to gallstones, is a common surgical disorder in Korea. Detailed microscopic descriptions, particularly the ultrastructural changes, of these diseases were not available. The goal of this study was to identify the ultrastructural alterations of gallbladder epithelium in cholecystitis with and without a stone, according to the degree of severity of inflammation, and the nature of the stone. The gallbladders of the control group, and cholecystitis cases without stone and with stone were fixed and examined with routine stain, special stain, immunohistochemical stain and trans-mission electron microscopy. The number and the volume density of the mucin containing secretary granules were not significantly increased in the calculous cholecystitis cases compared with those of the acalculous cholecystitis cases. Major findings were that the calculous cholecystitis cases showed a markedly reduced total lysosome area and volume density of the lysosome compared with those of the acalculous chole-cystitis cases. The differences between the mucin secretary granules and lysosomes, according to the degree of severity of cholecystitis and the natures of gallstones, were statistically not significant.

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.
