The purpose of this study was to investigate the angle formed by the Sella-Nasion(SN) plane and Frankort-Horizontal(FH) plane and evaluate the correlation and difference of the FH plane to other horizontal reference planes. Through this study we hope to present a basis for selecting a horizontal reference plane which can be implemented in cephalometric studies and in surgical orthodontic treatment planning. 600 subjects were chosen following a clinical examination and lateral cephlometric X-rays were taken. According to cephalometric analysis the subjects were classified into 3 groups; Skeletal Class I malocclusion or normal occlusion group(male 50, female 50), Skeletal Class II malocclusion group(male 50, female 65) and Skeletal Class III malocclusion group(male 50, female 50). The results were as follows. 1. The angle formed by the SN plane and FH plane showed no difference among the malocclusion groups, but there was a significant sex difference. For males the angle measured was 7.47degrees+/-2.40degrees whereas for females it was 8.93degrees+/-2.72degrees. 2. The angle formed by the SN plane or FH plane and Mandibular plane was higher in females for all malocclusion groups. This angle in the Skeletal Class I malocclusion group was 1 awer than in the other two groups. 3. There was no difference among the sexes or malocclusion groups con ,idering the angle formed by the FH plane and Palatal plane. 4. The gonial angle in the Skeletal Class III malocclusion group was higher than in the Skeletal Class I and Class II malocclusion groups- in both sexes.

Black hairy tongue is the name given to the appearance of an abnormal coating of the tongue and occurs in adults. It is the result of hyperkeratosis of the filiform lingual papillae which, on gross examination appear hair-like with a variable tinctorial aspect from yellow-brown to black. The pathogenesis is unknown. A number of etiologic factors have been implicated including the administration of topical or systemic antibiotics, poor hygiene, smoking, alcohol and the use of mouthwashes. We report a case of black hairy tongue that may be associated with oral administration of minocycline.

The Brunner's gland adenoma is characterized by a nodular proliferation of histologically normal Brunner's gland, accompanied by ducts and scattered stromal elements. First descrived by Salvioli in 1876, the tumor is relatively rare, with 119 cases reported by 1977, The most common benign tumor of the small bowel is the adenoma, 25% of which occur in the duodenum. They make up 30% to 50% of all hyperplastic polyps of the duodenum. Most frequently these tumors are discovered in patients in the fourth to sixed decades of life, though the age in reported caes ranges from l 1 days to 80 years. The benign tumors of the duodenum 30% to 50% contain elements of Brunner's gland and 10.6% of them are adenomas of Brunner's gland. We report a case of Brunner's gland adenoma treated by endoscopic polypectomy in 63 year-old woman, and reviewed the literatues of adenoma of the Brunne'r gland.

Condyloma acuminata represent a difficult therapeutic challenge, especially to infants and children who are unable to endure the pain during the treatment process. All the conventional treatments including cryotherapy, CO2 laser ablation cause pain and postoperative scars. It may be traumatic mentally to the infants and children as well as physically. Pulsed dye laser has been introduced as the new treatment of verruca. The results of the pulsed dye laser treatment of verruca have been inconsistent. However, it showed many advantages, such as no need for anesthesia, no destruction of collagen tissue, and the fact that mast patients may remain ambulatory. With the experience of our patient treated by pulsed dye laser, we suggest that pulsed dye laser may be an alternative choice of treatment for condyloma acuminala in children and infants with less pain, no scarring, use of simple anesthesia, less difficulty in management of postoperative wound.

This study was performed to evaluate soft tissue cephalometric norms for Korean adults which can be implemented in surgical orthodontic treatment planning using selected horizontal reference plane especially for Koreans (Male: SN-7.5degreeC, Female: SN-9.0degreeC) and a simplified analytical method. 70 males and 70 females consisting of freshmen of Yonsei University from 1996 to 1997 and students from the Dental College of Yonsei University were chosen according to clinical examination and cephalometric analysis. The samples had normal profiles, normal anteroposterior skeletal relationship(ANB angle of 0degreeC to 4degreeC and Wits appraisal of -4.0mm to 0mm), and Class I molar and canine relationship. They had no missing or supernumerary teeth and had no experience of orthodontic or prosthetic treatment. After the selection of 15 soft tissue landmarks and the construction of horizontal and vertical reference lines, 25 measurements were taken. These consisted of vertical and horizontal linear measurements and angular measurements. The results were as follows. 1. Mean and standard deviation of the measurements were calculated in males and females. 2. Vertical measurements were comparably bigger in males than females whereas anterior facial height ratio(sN-Sn/Sn-sMe) and lower anterior facial height ratio(Sn-Stms/Stmi-sMe) showed no significant difference between sexes. 3. Most of the horizontal measurements in relation to the vertical reference line(G-perpendicular) showed no significant difference between sexes. 4. Nasofacial angle, columellar angle, nasolabial angle and facial contour angle showed no significant difference between sexes. 5. The upper and lower lip were positioned about -1.0+/-2.0mm and +1.0+/-2.0mm in relation to the Ricketts' esthetic line in both sexes. In this study, soft tissue cephalometric norms of Korean adults for orthognathic surgery were obtained.

BACKGROUND: The purpose of this study was to evaluate mivacurium in the pharmacokinetics of onset and offset. METHODS: In 127 adult patients of ASA physical status I or II without any factors involving the neuromuscular function under general anesthesia, onset time (lag and manifest time) and clinical duration were measured after bolus or divided doses of ED95 x 2 of succinylcholine (SCC), rocuronium (ROC), atracurium (ATR), mivacurium (MIV), pancuronium (PAN) or vecuronium (VEC). Recovery time was defined as the recovery index and total duration measured after subsequent ED95 of MIV at 25% recovery of control twitch height from neuromuscular block induced by ED95 x 2 of ATR, MIV, PAN or VEC. Plasma cholinesterase (PChE) levels were measured following PAN or ATR. RESULTS: Onset time was faster with SCC and ROC, the low potency drugs, than with ATR, MIV, PAN or VEC, the high potent drugs. Manifest time was shorter in low potency drugs but longer in high potency drugs than lag time after bolus or divided doses of muscle relaxants given. Divided doses of various drugs induced a shortened onset time, but the patterns of relationship between lag and manifest time associated with drug potency did not alter. The recovery times with administered MIV were slowest after PAN pretreatment, and fastest after MIV pretreatment. PChE levels decreased significantly from 3 min to over 180 min after PAN administeration but not ATR. CONCLUSIONS: The onset time of MIV was not improved due to high drug potency as other nondepolarizing neuromuscular blockers. However, in spite of high potency, the recovery time of MIV was faster than other drugs. This results may be depend upon PChE activity rather than drug potency. Additionally, the prolonged recovery of MIV was not only under the influence of low PChE activity but also other some factors such as: the first relaxants administered before MIV dominated the neuromuscular block so that the duration of MIV given subsequently changed to resemble that of the first. The longer elimination half-life of the underlying relaxant prolonged the effects of subsequentshorter acting MIV. Structural similarities or dis-similarities between the interacting MIV and other drugs may have effects more potent in dis-similarity than in similarity.

BACKGROUND AND PURPOSE: Primary involvement of the peripheral nerves in myotonic dystrophy type I (MyD1) is controversial. We investigated whether the involvement of peripheral nerves is a primary event of MyD1 or secondary to another complication such as diabetes mellitus (DM). METHODS: The subjects comprised 12 patients with MyD1, 12 with DM and no peripheral nerve involvement, and 25 healthy volunteers. We measured multiple excitability indices in the median motor axons. The strength-duration time constant was calculated from the duration-charge curve, the threshold electrotonus and current-threshold relationships were calculated from the sequential subthreshold current, and the recovery cycle was derived from double suprathreshold stimulation. RESULTS: The depolarizing and hyperpolarizing threshold electrotonus were significantly reduced and exhibited increased refractoriness in the MyD1 group compared with the DM and control groups. The SDTC, superexcitability, and subexcitability were not significantly altered in the MyD1 group. CONCLUSIONS: The MyD1 group exhibited a depolarized axonal membrane potential. The significant differences in peripheral nerve excitability between the MyD1 group and the DM and normal control groups suggest that peripheral neuropathy is a primary event in MyD1 rather than a secondary complication of DM.

PURPOSE: This study was performed to investigate the change of weight and body composition, and lipid profiles in the idiopathic epileptic children treated with valproate. METHODS: We measured the weight, height, left arm circumference, left triceps skinfold thickness of 30 idiopathic epileptic children treated with valproate before, at 1 month and 4 months of treatment. We also analyzed the serum lipid profiles of the patients before and at 4 months of treatment. We analyzed the change of Body Mass Index (BMI), Arm Muscle Area(AMA), Arm Fat Area(AFA), and the serum lipid profiles. Two-way analysis of variance, chi-square test and paired-t test were used for statistical analysis. RESULTS: There was no statistically significant change in BMI, AFA, AMA of the patients. But the weight of 13(44.3%) children increased greater than 10% with valproate treatment. AMA were not changed, but AFA were significantly increased, 791.2+/-209.6 mm2 before treatment, 858.1+/-246.6 mm2 at 1 month, 1051.7+/-393.2 mm2 at 4 months, in 13 patients, whose weight gain were greater than 10%(P<0.05). There was no change in cholesterols, low density lipoproteins, high density lipoproteins of the 30 children. CONCLUSION: The increase of the weight in the children treated with valproate resulted from the increase body fat. So the weight gain may be a risk factor of obesity
