2.A study on the morphologic differences between long-face adults and normal-face adults on the lateral and P-A cephalograms.
Korean Journal of Orthodontics 1990;20(2):293-304
The purpose of this study was to describe the morphologic differences between long-face adults and normal-face adults on the lateral and P-A cephalograms. Long-face and normal-face subifects were selected clinically, and then each of them was taken the lateral cephalogram. According to SN-MP angle and ATFH on the lateral cephalogram, long-face group and normal-face group were classified. 2 long-face adults and 18 normal-face adults were collected, and each of them was taken the P-A cephalogram. The results were as follows: 1. The morphologic differences between long-face adults and normal-face adults were closely related to mandibular morphology. 2. Long-face adults, compared with normal-face adults, demonstrated significant increase in ALFH, and significant decrease in ramus height. 3. Long-face adults, compared with normal-face adults, demonstrated significant increase in AUDH and, ALDH, especially in ALDH. 4. On the P-A cephalogram, no measures of transverse dimension demonstrated significant differences between two groups. 5. On the P-A cephalogram, facial height/facial width ratio was significantly larger than normal in the long-face adults, and in the normal-face adults, facial height/facial width ratio was approximately 90%. 6. In the correlation analysis of SN-MP angle and ATFH with all the other variables, the correlation coefficients of SN-MP angle and PTFH/ATFH that of ATFH and ALFH on the lateral cephalogram demonstrated the highest value, and on the P-A cephalogram, SN-MP angle and Cg-GA-Me (Lt.), ATFH and lower facial height demonstrated the highest value of correlation coefficients.

OBJECTIVE: Fetal heart rate in embryos(6-8 gestational weeks) have been significantly related to fetal outcome, but have rarely been studied. We attempted to identify fetal heart rate during 6-8 gestational weeks. Our purpose was to determine the lower limit of the heart rate associated with a favorable outcome and to evaluate the prognosis for those embryos with slow heart rates in early period. METHODS: We prospectively studied 798 singleton pregnancies between Jul. 1997-Dec. 1999 visiting our hospital. Gestational age was calculated from the beginning of the last menstrual period in the case of regular cycle and was confirmed by the crown-rump length. Other cases were measured by crown-rump length or mean gestational sac diameter. Color doppler sonography was used to calculate the fetal heart rate in beats per minute as the mean of 3 waves. RESULTS: Mean fetal heart rate (+/-SD) were 114.08+/-15.40 bpm for group 1, 126.49+/-18.78 for group 2, 139.83+/-19.92 for group 3, and 149.58+/-23.34 for group 4(p<0.001). Prognosis in the first trimester improved as heart rate increased to 100 bpm in group 1 and 120 bpm in group 2. In group 3 and 4, most of fetus with heart rates below 110 bpm died. CONCLUSIONS: The fetal heart rate during 6-8 gestational weeks is associated with fetal outcome at the end of the first trimester and we can identify the fetuses that are in risk.

We treated 4 patients with uric acid calculi in the renal pelvis or ureter with alkaline fluid irrigation through percutaneous nephrostomy (PCN) tube. Initial presentations were anuria or severe flank discomfort, we performed PCN to relieve such obstructive symptoms caused by uric acid calculi. We tried to dissolve uric acid calculi with normal saline mixed to sodium bicarbonate through a PCN tube. The success of therapy is believed to be related to the direct and constant urinary alkalinization effect obtained with irrigation compared to be the intermittent alkalization that occurs when oral agent are used.

This study was carried out as a part of the semi-longitudinal study on growth and development of Korean children, with purpose of observing the growth change in arch form, 736 pairs of study models were taken for 3 years. Mesio-distal diameter of each tooth, intercanine width, intermolar width, canine arch depth, molar arch depth and arch perimeters were measured. Afterwards, mean value and each standard deviation of each age group and each gender were obtained, and corresponding graphs were drawn. The following conclusions were obtained: 1. Mesio-distal diameters of maxillary central incisor, maxillary 2nd molar, mandibular canine, and mandibular 2nd molar showed statistical differences between boys and girls. 2. Intercanine width shows a gradual increase until age of 11. 3. Intennolar width in maxilla shows continuous increase, and the tendency of increase is more apparent between age of 9 and 14. In mandible, various pattern was shown until age of 9, and after, a slight increase. 4. Canine arch depth shows the increasing tendency until age of 13 in maxilla and 11 in mandible. 5. Molar arch depth shows the pattern of increase until age of 10 in male and 9 in female, which is more apparent in maxilla. After age of 9 or 10, dereasing pattern was significantly shown until age of 15 in maxilla and age of 12 in mandible. 6. Arch perimeters in maxilla and mandible showed gradual increase until age of 10, and the tendency of increase was more apparent in maxilla; however, between the age of 10 and 14, arch perimeters of maxilla and mandible showed gradual decrease which was more apparent in mandible.

We tried to evaluate frequencies and severities of malocclusion of various socioeconomic areas according to growth and development. To obtain objective validity, we used Handicapping Labiolingual Deviation (HLD) suggested by Draker, Treatment Priority Index (TPI) by Grainger, Handicapped Malocclusion Assessing Record (HMAR) by American Dental Association and American Association of Orthodontist. Seoul and Kwangju were selected as an urban group, Ahnyang as an middle socioeconomic group and Hwasun near the Kwangju area as an rural group. 140 (male 63, female 73) of 5th grade in 'E' elementary school students in Seoul, 202 (male 101, female 101) of 'S' elementary school students in Kwangju, 207(male 105, female 102) of 'H' elementary school students in Hwasun, and 100(male 49, female 51) of 'M' elementary school students of in Ahnyang of all the same grade were analyzed and we obtained the results as follows; 1. TPI, HLD, and HMAR showed high coincidence and reproducibility between different observer. (p<0.01) 2. In comparison of TPI, HLD, and HMAR according to clinical decision, there was statistically difference between each other. (p<0.01) 3. As the severity of malocclusion increases there was high correlation between TPI and HLD, and between HLD and HMAR (p<0.05) 4. With respect to differences between areas in TPI and HLD, there was statistically difference between Ahnyang and other areas. 5. In Seoul as an urban group there was a high incidence of periodic checkup and history of orthodontic treatment than other area. 6. Mode of feeding and posture during sleeping did not affect the severity of malocclusion. As a conclusion, TPI, HLD and HMAR are so reproducible and coincident that they can be used as a guide on evaluating the frequency and severity of malocclusion and determining the priority of orthodontic treatment to determine the need and supply of orthodontic treatment. Furthermore these indices can provide objectively valid data for establishing public health problem solution.

Enlow's counterpart analysis explains the complex with anatomic and developmental characteristics where craniofacial aspect of individuals has been developed. Counterpart analysis does not compare individual measurement with the normal value from the average of majority but analyzes by comparison of values that each individual has. In this study we examined surgical changes in skeletal Class III malocclusion patients(male 40, female 40) and compared them with normal occlusion patients using counterpart analysis. The results indicated that : 1. Skeletal anterior-posterior discrepancy was relieved by shortening of the ramus width(B3). 2. The ramus alignment(R3, R4) was displaced posteriorly and the occlusal plane angle(R5) was rotated clockwise. 3. Skeletal Class III pattern was relieved in the post-operative group, but differences in the level of the cranium(R1, R2) was remaining compared to the normal occlusion patients. 4. In the comparison of surgery methods, the two-jaw surgery group presented changes in the maxillary length(A4), ramus alignment(R3,R4) and occlusal plane angle(R5) compared to the one-jaw surgery group, but the differences were not significant. In the past study about Korean skeletal Class III patients, the skeletal characteristics are upward backward rotation of the cranial base, posterior displacement of the maxilla, forward inclination of the ramus and lengthening of the mandibular body, but in this study, skeletal Class III pattern was relieved by shortening of the ramus width and maxillary advancement by orthognathic surgery, because orthognathic surgery is usually performed on limited areas in the maxilla and the mandible.

Distal hereditary motor neuropathy (dHMN) is a heterogeneous disorder characterized by degeneration of motor nerves in the absence of sensory abnormalities. Recently, mutations in the small heat shock protein 27 (HSP27) gene were found to cause dHMN type II or Charcot-Marie-Tooth disease type 2F (CMT2F). The authors studied 151 Korean axonal CMT or dHMN families, and found a large Korean dHMN type II family with the Ser135Phe mutation in HSP27. This mutation was inherited in an autosomal dominant manner, and was well associated with familial members with the dHMN phenotype. This mutation site is located in the ?-crystallin domain and is highly conserved between different species. The frequency of this HSP27 mutation in Koreans was 0.6%. Magnetic resonance imaging analysis revealed that fatty infiltrations tended to progressively extend distal to proximal muscles in lower extremities. In addition, fatty infiltrations in thigh muscles progressed to affect posterior and anterior compartments but to lesser extents in medial compartment, which differs from CMT1A patients presenting with severe involvements of posterior and medial compartments but less involvement of anterior compartment. The authors describe the clinical and neuroimaging findings of the first Korean dHMN patients with the HSP27 Ser135Phe mutation. To our knowledge, this is the first report of the neuroimaging findings of dHMN type II.

BACKGROUND: Since March 1, 1989, a new health care system has been introduced. But the departments of ENT, ophthalmology, dermatology and PMR (rehabilitation medicine) in tertiary health care hospitals were exempted from the new system and were allowed to see patients directly. Thereafter, the Ministry of Health revised the National Health Insurance regulation, and required the above departments to see patients only with referral. This study was done to analyze whether the revision has contributed to providing adequate specialized medical services and to know what role family physicians can assume under revision by analyzing the referred patients. METHODS: From November 1998 to June 2000 and from July 2000 to February 2002, both 20 months, we reviewed the charts of 331 patients who were referred from family medicine department of KHMC (Kyung Hee Medical Center) to the above four departments and analysis has done. RESULTS: During both periods, the number of cases increased from 94 to 237, and the patients group had no significant difference in age and sex. Reviewing the number of referred cases, before revision, cases were concentrated to the department of ENT and to PMR. After revision, cases were evenly distributed in three departments. except for PMR. Reviewing referral contents, the three departments except for dermatology showed no significant difference. CONCLUSION: The sum of cases increased by 2.5 times, but the three departments except for dermatology showed no significant difference in referral and diagnosis content. In dermatology, the majority of the patients wanted a referral with the objective of obtaining a referral paper. Therefore, we can consider that the revision didnot contribute to specialized medical services. But after revision, referral cases to ophthalmology and dermatology increased by 4 and 6 times. We recommend that family physicians know and experience more about these.

Journal of the Korean Surgical Society 1999;56(6):822-826
Enlargement of the thyroid gland is the most frequently encountered disorder of the endocrine system. A clinical evaluation is helpful in diagnosis but has its limitation. Until recently, surgical excision has been the only means by which a precise diagnosis of thyroid nodule is made, based upon the histopathologic evaluation. Authors studied 117 cases of thyroid nodule operated at Department of Surgery, College of Medicine, Hallym University, from January 1985 to July 1994. The results were analyzed with X2-test and summarized as follows. 1. The thyroid nodules were most frequently seen in third and fourth decades (57.3%), and more in female (5.9:1). 2. The most common symptoms and duration were palpable mass (97.4%) and within 3 months (41.1%). 3. Most cases of thyroid nodules were treated with lobectomy (41.0%). 4. On the radioisotope scanning, the incidence of malignant nodule with cold nodules was 17.9% and the incidence of benign nodule with hot nodule was 91.7%. 5. The overall postoperative and specific complications were only related to the histopathologic finding (P=0.0026, P=0.0207), and not related to the type of operation and size of the thyroid nodules.
