2.Hybrid Total Hip Replacement Arthroplasty: Minimum 3 Year Follow - Up Result.
The Journal of the Korean Orthopaedic Association 1998;33(2):246-253
Fifty-eight primary total hip arthroplasties with hyhrid cemented femoral component using contemporary cementing technique and cementless acctahular cup were followed for a minimum 3 year(ranged, 36 to 67 months, mean 4.1 years). Thc average age of the patients at the time of the operation was 54 years(ranged, 22 to 73 years). The preoperative common diagnosis were avascular necrosis of femoral head in 38 hips and miscellaneou. in 20 hips. The mean Harris hip score was 61 in preoperative and 91 in postoperative at last Follow-up. 5-1 hips(92%) were rated excellent and good clinically. One hip was revised for aseptic loosening of the femoral stem at 52 months follow-up. Radiographically no acetahular component was loose. Three femoral stems were definitely loose, one stem was classfied as prohahle loosenine and another one was ratde as possible loosening. There was no progressive radiolucent dermaation ol' cement-hone interf'ace in stable fermoral steni. Non progressive cement-bone radiolucency was lound seven hips in zone 1, two hips in zone 6, one hip in zone 2 and one hip in zone 7 at last follow-up. There were two postoperalive dislocations. Other complications included superficial infection(two hips) and sciatic nervc palsy(one hip). Our experience showed that the hyhrid hip replaccment with improved cementing technique provided satisfactory results at minimum 3 year follow-up study and emphasized the importantance of careful cementing techniques in survival ot cemented I'cmoral stem.

Korean Journal of Aerospace and Environmental Medicine 1999;9(1):83-89
This study is based on the result of oral examination of 'A' airliner employees in the period of June 1997 and December 1997. The purpose of this study is to analyze the distribution of dental diseases among workers and the relationship between income level and dental healthiness. Based on the above analysis, this study further tries to indirectly evaluate the method of prophylaxis. Following is the list of basic findings of this study: Firstly, it was found that male workers tend to have inferior dental condition compared with female workers. Also, dental condition of technicians was found to be worse than that of office workers. Secondly, it was found that dental caries decreased with the age. However, periodontal disease was increasing with the age. Therefore, this result leads us to convince that the education should be focused on 'how to brush your teeth' in order to prevent periodontal diseases. Thirdly, more than 40% of the examined were found to be carrying dental calculus related diseases (67.2%) and cervical abrasion (40.5%), respectively. In conclusion, we became to know that the treatment of cervical abrasion and dental calculus at the Dental Clinic is effective in helping 'A' Airliner employees to have better dental status.

Background: It is well known that the addition of CO2 gas during cardiopulmonary bypass (CPB) can increase cerebral blood flow (CBF). In this study, we tried to find whether the increase of CBF by CO2 gas could be expressed on the measurement of body temperatures. Methods: This study included 22 adult patients who underwent CPB with moderate hypothermia and were assigned randomly to two groups by adding CO2 gas (CO2 group and Air group). We measured each tympanic (TM), nasopharyngeal (NP), oral, forehead, finger, rectal and CPB arterial line temperatures of CPB circuit for 20 times during cooling in every one minute for 20 minutes and during rewarming every two minutes for 40 minutes. Results: During cooling and rewarming, the TM, NP and oral temperatures changed more rapidly than the rectal and finger temperatures. In TM temperature, as time changed, the percent changes of temperature varied more prominently in the CO2 gas group than in the Air group. The statistical differences were significant especially during 13 minutes to 20 minutes in cooling and 8 minutes to 20 minutes during rewarming. Conclusion: From this data, we can postulate the effect of CO2 gas on CBF indirectly by measuring several sites of body temperatures.

5.The Usefulness of High Resolution Ultrasonography in the Differentiation of Thyroid Nodule.
Journal of Korean Society of Endocrinology 2005;20(3):242-251
BACKGROUND: Fine needle aspiration(FNA) is regarded as the best procedure in the diagnosis of thyroid malignancies. However, the rate of false negative and indeterminate results are between 5~10 and 10~30%, respectively. Therefore, a new diagnostic tool to assist FNA is required. Recently, high resolution ultrasonography(US) has become a useful tool in the detection of malignant thyroid nodules. Therefore, the sonographic characteristics differentiating malignant from benign nodules were analyzed, and the usefulness of US in the diagnosis of thyroid malignancy assessed. METHODS: Of the 212 patients that underwent surgery due to a thyroid nodule, at the Daegu Catholic University Hospital between January 2002 and June 2004, and 181 patients(199 nodules) who underwent high resolution US examination before surgery, were included in this study. The characteristics of the sonographic parameters, such as depth/width ratio, shape, margin, structure, sponge sign, calcification and halo, and the homogeneity and echogenicity of the solid component and invasion, were observed. RESULTS: In a univariate analysis of the nonfollicular neoplasms, the depth/width ratio, shape, margin, structure, calcification and halo, and the homogeneity and echogenicity of the solid component were found to be significant parameters. The "sponge sign", a new parameter suggested by us, was found only in benign nodules. In a multiple logistic regression analysis, only the depth/width ratio, shape, presence of calcification and echogenicity of the solid component were significant parameters. According to the results of the multiple logistic regression analysis, the point and estimate of each characteristic of the significant parameters were found, and a formula for calculating a score for the prediction of malignancy computed. At a score of 0.44, the sensitivity and specificity of US were 85.9 and 88.7%, respectively. In a univariate analysis of follicular neop-lasms, the shape, calcification and echogenicity were found to be significant parameters. CONCLUSION: It was conclude that high resolution US is a very useful tool in the differentiation of benign and malignant nodules, especially in nonfollicular neoplasms. It is also suggested that the "sponge sign" might be used as a strong indicator for the confirmation of benign nodules

Familial isolated primary hyperparathyroidism(FIPH) is associated with multiple endocrine neoplasia type 1 (MEN1) syndrome, primary hyperparathyroidism accompanied by jaw-tumor syndrome, and familial hypocalciuric hypercalcemia. FIPH may be an early stage of MEN1 or an allelic variant of MEN1. Thymic carcinoid tumor is a rare tumor in MEN1 syndrome. Here, the authors report the case of a 40-year-old man diagnosed with recurrent thymic carcinoid tumor and FIPH. Both the patient and his elder sister had been previously diagnosed to have FIPH with a novel frameshift mutation in the MEN1 gene. Initially, the patient underwent thymectomy because of an incidental finding of a mediastinal mass in his chest X-ray, and had remained asymptomatic over the following 4 years. Pancreas computed tomography conducted to evaluate MEN1 syndrome revealed anterior and middle mediastinal masses, and resultantly, massive mass excision was performed. Histological findings disclosed atypical carcinoids with infiltrative margins. In view of the thymic carcinoid tumor relapse that occurred in this patient, the authors recommend that regular pancreas and pituitary imaging studies be conducted for FIPH associated with a MEN1 gene mutation.

8.A Typical Korean Case Of Carney Complex.
The Korean Journal of Internal Medicine 2003;18(4):260-265
Carney complex is a multiple neoplasia syndrome, inherited in an autosomal dominant manner, that is characterized by lentigines, cardiac myxoma, and numerous endocrine and other tumors, including primary pigmented nodular adrenocortical disease. Here, we describe a typical case of Carney complex in a 27- year-old female who exhibited spotty skin pigmentation on the lips, oral mucosa, fingers, and toes and several manifestations of Cushing's syndrome due to primary pigmented nodular adrenocortical disease. She also had pituitary adenoma, breast tumor and thyroid nodule. Only a few cases of this disorder have been reported in the Korean literature. All of them, however, had only two components of Carney complex: composed of skin pigmentation and primary pigmented nodular adrenocortical disease. Therefore, the present case seems to be the first true case of Carney complex reported in Korea.

Hip & Pelvis 2021;33(3):154-161
Purpose:
Although proximal femoral nail antirotation (PFNA; Synthes, Switzerland) has demonstrated satisfactory results when used for the treatment of intertrochanteric fractures, mechanical complications may occur. To better quantify the risk of mechanical complications when proximal femoral nail antirotation is used to treat intertrochanteric fractures, this study aimed to: (1) characterize the frequency of mechanical complications and extent of blade sliding and their correlation with reduction quality and (2) identify factors associated with mechanical complications.
Materials and Methods:
A review of medical records from 93 patients treated for intertrochanteric fractures with a minimum of 6-months of follow-up between February 2014 and February 2019 was conducted. Blade position was evaluated using Tip-apex distance (TAD) and Cleveland index. The extent of blade sliding was evaluated using the adjusted Doppelt’s method for intramedullary nailing. Individuals were classified as having or not having mechanical complications, and reduction quality and radiologic outcomes were compared between the two groups.
Results:
Mechanical complications occurred in 12 of 94 hips (12.8%), with 11 out of 12 being from the intramedullary reduction group. There was no significant difference in TAD between groups; however, there were significant differences were noted in Cleveland index, AO/OTA classification, reduction quality and extent of blade sliding. The mean blade sliding distance was 1.17 mm (anatomical group), 3.28 mm (extramedullary group), and 6.11 mm (intramedullary group), respectively (P<0.001). Data revealed that blade sliding was an associated factor for mechanical complications (odds ratio 1.25, 95% confidence interval 1.03-1.51).
Conclusion
The extent of blade sliding determined using the adjusted Doppelt’s method was significantly associated with mechanical complications suggesting that prevention of excessive sliding through proper intraoperative reduction is important to help achieve satisfactory treatment outcomes.
