  • This study built the volcano Data Base(DB) of 289 active volcanoes around the Korean Peninsula, Japan, China (include Taiwan), and Russia Kamchatka area. Twenty nine more hazardous volcanoes including Baekdusan, Ulleungdo and 27 Japanese volcanoes that can cause a widespread ash-fall on the Korean peninsula by potentially explosive eruption were selected. This selection was based on the presence of volcanic activity, whether or not containing dangerous explosive eruption rock types, distance from Seoul, and volcanoes having Plinian eruption history with volcanic explosivity index (VEI) 4 or more. The results of this study are utilized for screening high-risk volcanoes that may affect the volcanic disaster caused by a widespread fallout ash. By predicting the extent of spread of ash caused by these hazardous volcanic activities and by analyzing the impact on the Korean peninsula, we suggest that it should be used for helping to predict volcanic ash damages and conduct hazards mitigation research as well.

  • The purpose of this study was to find out the prevalence of dental anomalies in 600 normal persons (male:363, female:237) at age 14 to 39 years, through history taking, oral examination, and radiographic observations of subjects. The obtained results were as follows: 1. The prevalences of individual dental anomalies were as follows; Congenitally missing teeth 7%; supernumerary teeth 1.33%; ectopic eruption; 8.50%, transposition;0.33% rotation; 23.67%, microdontia;11.16%(peg lateralis;5.33%, third molar;5.83%), prolonged retention of deciduous teeth;1.33%, crowding 49.83%, and spacing;15.17%. 2. Alterations in numbers of teeth : The most frequently missing teeth were mandibular lateral incisors, followed by mandibular second premolars and maxillary second premolars. In numbers of congenitally missing teeth per person, 52.38% had one missing tooth and 30.95% had two missing teeth. In supernumerary teeth, there was higher rate in male than in female. Most supernumerary teeth were mesiodens of median area in maxilla and the eruption pattern of that teeth generally was unerupted state. 3. In transposition, exchange of position of teeth involved the canine and first premolar. 4. Congenital missing rate of permanent successors in prolonged retention of deciduous teeth was 69.23%. 5. Crowing and spacing had respectively higher rate in mandible and in maxilla.

  • This report details a case of 8-year-old girl showing failure of odontogenesis after chemo-radiation therapy for the rhabdomyosarcoma at the age of 4. The observed results were as follows : 1. Past history revealed that she had received for a total radiation dose of 4430cGy, 29 fractions in 6 weeks and chemotherapy with vincristine, actinomycin D and cytoxan, followed as maintenance phase for 2 years. 2. The patient was symptom -free and appointed for the treatment of multiple dental caries. 3. Oral examination showed hypoplastic enamel on whole erupted permanent teeth and showed retarded eruption. 4. Conventional radiograms showed failure of root development including abrupt cessation of root formation and root agenesis, and microdontia, missing teeth, irregular enamel, dislocation of the impacted teeth. Additional finding showed good healing bone pattern on the left mandibular ramus and angle area. 5. Cephalometric analysis revealed failure of bite raising due to incomplete eruption of all the first molars and made it possible to suspect entrapped mandibular growth and then Class II tendency growth. 6. There was correlation between the time of chemo-radiation therapy and the damage of the teeth.

  • Zoster sine herpete (ZSH) is a varicella zoster virus (VZV) reactivation without a zoster that is difficult to diagnose early after onset. This study examined 12 patients who presented with intercostal neuralgia, had no history of trauma, cutaneous eruption and no scar of a herpes zoster on the lesion. Two patients had a vertebral compression fracture. Two patients had a history of a zoster in the other site. No other suspicious findings were observed. Ten of the twelve patients were checked for the IgG and IgM varicellar zoster virus antibody. All the patients tested positive to the Ig G antibody test and only one patient tested positive to the IgM antibody test. One patient was confirmed to have ZSH and the other patients were suspected of having ZSH. All the patients were treated for postherpetic neuralgia, resulting in a significant decrease in the intercostal neuralgia.

  • The results of the study about comparison of Eastern-Western medicine on the Atopic dermatitis were as follows. 1. Atopic dermatitis is chronic eczematous dermatosis which have severe itching, characteristic eruption, easily occur region and pass on chronic relapsing progress and have family history of Atopic disease and hereditary disposition. 2. Atopic dermatitis assume an remarkable clinical aspect and it's diagnosis depends on family history and clinical symptom. 3. In all cases of Western medical treatment is nothing but a symptomatic treatment because can not find out certainly the cause of Atopic dermatitis. 4. Atopic dermatitis is belong to the category of the 'Naesun(내癬)', 'Taeryumchang(胎斂瘡)', 'Samanpoong(四灣風)' etc. in Oriental medicine. 5. The etiology and pathogenesis of Atopic dermatitis in oriental medicine are congenital defect(稟賦不足), internal accumulation of damp and heat(濕熱內鬱), improper diet(飮食不節), exogenous pathogenic factors(外邪侵襲), etc.. 6. The treatments of Atopic dermatitis in oriental medicine are thought effective clear up heat and remove dampness with febrifugal arld diuretic drug(淸熱利濕), invigorate the spleen to resolve dampness(健脾燥濕), nourish Um and blood to relave dryness(滋陰養血潤燥), etc..

  • Irritation fibroma is a common hyperplastic lesion of the oral mucosa that can occur in response to chronic irritation or trauma. This report presents an unusual case of irritation fibroma associated with ectopic eruption of the maxillary left central incisor in a patient with Angelman syndrome. Considering the patient's medical history and cooperative ability, excisional biopsy under intramuscular sedation using midazolam was performed. The patient exhibited successful healing without lesion recurrence. It is important to perform histopathological examination followed by excisional biopsy, because other benign or malignant tumors may mimic the clinical appearance of an irritation fibroma.

  • A 72-year-old female patient was presented complaining of unbearable abdominal pain in the upper left quadrant at our hospital. Two weeks earlier she had developed a vesicular eruption on the right C3 dermatome and 1 week earlier she had experienced a vesicular eruption on the left T11 dermatome. Her medical history was unremarkable. She had suffered from severe abdominal pain in the upper left quadrant for 10 days and the mild pain in the right shoulder region for 20 days. The pain in the upper left quadrant had increased and was unresponsive to drugs prescribed by the local clinic. And we performed T11 root block with 0.5% lidocaine 5 ml and dexametasone 5 mg, and thoracic epidural blockade on 1st hospital day under diagnosis of herpes zoster infection. Her VAS were improved from 10 to 2 on 2nd hospital day. We performed thoracic epidural blockade with 0.5% lidocaine 6 ml. Her VAS were changed from 2 to 7 and so then we performed the thoracic epidural blockade with 0.5% lidocaine 5 ml and triamcinolone 40 mg on 3rd hospital day. On 4th hospital day, her VAS were from 7 to 1. After 4 month of our managements she was tolerable without any medications.

  • Incontinentia pigmenti(IP), so called Block-Sulzberger syndrome is a rare genodermatosis that occurs almost in female infant; usually lethal in males, X-linked dominantly inherited disorder. IP is characterized by abnormalities of mesodermal and ectodermal tissues including eye, tooth, skin, nail, breast and hair as well as neurological deficiencies. Dental problems are congenital missing of teeth, delayed eruption, abnormal crown shape and so on. Here is a case of 6 year-old female with IP. She had congenital missing of primary and permanent teeth, delayed eruption, maxillary deficiency and extra cusps, resulting in unstable occlusion. Systemically, she had a history of operating eyes due to problem of retina and hyperpigmented macules on her trunk and extremities as typical character of IP.
