A carefull inspection of an AP X-ray of a normal hip reveals in the weight-bearing surface of the ilium a curved area of dense bone, called SOURCIL by Pauwels (1963). The configuration of this dense area is semilunar and represents subchnodral bony eburnation due to a respose by the articular portion of the ilium to the stress provoked by the compressive force acting on it. However, in many cases of idiopathic avascular necrosis of the femoral head, changes in SOURCIL may be seen. So we reviewed our 49 patients (unilateral 16, bilateral 33) since 1983 with comparison to normal hips (100 persons). The results are as follows; 1. SOURCIL is not visible at birth and by walking, it is developed with age and has the adult configuration at the age of 18. It is thought the configuration and sloping angle of SOURCIL is not changed with age after skeletal growth is completed. 2. Although the position of the X-ray tube may be changed, the shape and angle of SOURCIL is not changed significantly. 3. The average SOURCIL angle is 2.1° in normal hip group and 3.5° for the avascular necrosis group but, there is no meaningful statistical differences. It seems to be meaningful that the mean SOURCIL angle is 10.3° for patients under the age of 35 in avascular necrosis groups (9 persons). 4. If a high SOURCIL angle (about 10° or more) is present, the hemiarthroplasty such as bipolar endoprosthesis should be avoided because there is biomechanically far more wearing of the acetabular roof after that kind of operation. If inevitable, deepening the acetabulum by reaming is recommended for prevention of superolateral migration of prosthesis after operation. 5. With close observation of SOURCIL before and after operation, one can easily point out what is able to predict the prognosis on the biomechanical basis.

Crohn's disease is a rare inflammatory bowel disease in Korea which requires a differential diagnosis with intestinal tuberculosis. In the early stages of Crohn's diseaae, the combiation of bowel wall edema and spasm produces intermittent obstructive manifestations, so the usual subjective symptoms were appeared long standing diarrhea, low grade fever and abdominal pain and distension. We recently experienced a case of Crohn's colitis with repeated bowel obstruction in female adult who underwent surgical resection.

PURPOSE: Neutrophils are central to the defences against bacterial infection, and in neonates the number of neutrophils are decreased due to inhibited production and phagocytic function. This induces high mortality rates in infants suffering from neonatal sepsis. Exogenous GM-CSF can increase the number of neutrophils and improve the phagocytic function. To establish the most cost effective dose of exogenous granulocyte-macrophage colony-stimulating factor in infected neonates, we divided infected patients into two groups. The serum level of granulocyte-macrophage colony stimulating factor, white blood cell count and absolute granulocyte count were compared. METHODS: This study included 22 infants with infection, admitted to the neonatal intensive care unit of Chungnam National University Hospital, between February 1998 and September 1999. Infected infants were divided into two treatment groups with exogenous GM-CSF 3 microgram/kg/day & 10 microgram/kg/day. The total WBC count, the absolute granulocyte count and the serum GM-CSF concentration of peripheral blood before use of GM-CSF, and those of 2nd, 5th and 7th day after use were compared. RESULTS: In 3 microgram/kg/day group, WBC count and the absolute granulocyte count and the serum GM-CSF concentration reached a peak after the 2nd injection of GM-CSF. In 10 microgram/kg/day group, the WBC count and the absolute granulocyte count increased gradually until 7th day. There was tendency for the total WBC counts, the absolute granulocyte count and the serum GM-CSF concentration of peripheral blood in 10 microgram/kg group to increase more than those of 3 microgram/kg group, after exogenous GM-CSF treatment. CONCLUSION: In neonates, we propose the exogenous GM-CSF treatment 10 microgram/kg/day as being more effective than 3 microgram/kg/day protocol, which is one of the safest and most effective methods to increase the total WBC count, the absolute granulocyte count and the serum GM-CSF concentration of peripheral blood.

PURPOSE: To evaluate the psychometric properties of the Korean short form-36 health survey version 2 for assessing the general population and to provide normative data on the general population. METHODS: Six hundred members of the general Korean population were recruited using a multistage quota sampling method. Data quality was evaluated in terms of the completeness of the data and the response consistency index. Each psychometric property was evaluated using descriptive statistics, item internal consistency, item discriminant validity, known-group validity, internal consistency reliability, and exploratory factor analysis. RESULTS: The rate of missing data was low, and the rate of consistent responses was similar to conventional criteria. Item internal consistency was acceptable across all scales, whilst item discriminant validity was satisfactory for five of the eight scales. Social functioning was the least acceptable in terms of not only item discriminant validity but also item consistency reliability (Cronbach's alpha = .64). Test-retest Pearson correlation coefficients ranged from .54 to .80. In known group comparison, male sex, age <60 years, high educational status, and the absence of any comorbidities were associated with higher scores than their counterparts. Item factor analysis yields the presence of six factors, accounting for 68.8% of the variance. CONCLUSION: The findings of this study generally support the use of the Korean short form-36 version 2 for evaluating the general population, although caution is recommended when interpreting the vitality, social functioning, and mental health scales. Further research is needed in Korea.

OBJECTIVES: This study was conducted to elicit quality weights for 42 EQ-5D health states with the time trade-off (TTO) method from the general population of South Korea. METHODS: We selected the same EQ-5D health states as those in the UK MVH study. The Korean version of EQ-5D questionnaire and TTO method were used for the valuation process. We interviewed 500 people as a representative sample of the general population in Seoul and Gyeonggido. The result was compared with those from UK, Japan, and USA by Spearman's rank correlation and t-test. RESULTS: TTO values for 42 EQ-5D health states and 'unconscious' state were obtained from the general South Korean population. The best one was '11112' state and the worst one was 'unconscious' state. The states worse than death were '33323', '33333', and 'unconscious' states, which had negative TTO values. There was a strong correlation between TTO values of the EQ-5D health states and those of their corresponding states from UK, Japan, and USA (Spearman's correlation coefficient: 0.885, 0.882, and 0.944, respectively, p <0.001). However, absolute TTO values of most EQ-5D health states were significantly different from those of their corresponding states in other foreign studies (UK: 41/42, USA: 32/42, Japan: 15/17). CONCLUSIONS: We found that the Korean general population TTO values for EQ-5D health states were different from those of other foreign studies, suggesting that a specific Korean valuation set should be developed and used for economic evaluation studies in South Korea.

Broncho-gastric fistula caused by benign gastric ulcer perforation after esophagectomy is very rare. In general anesthesia of a patient with broncho-gastric fistula, in spite of hyperventilation, leakage of the anesthetic gases through fistula may make the patient hypercapneic, and positive pressure ventilation may increase the risk of the pulmanary aspiration by the regurgitation of gastric fluid by stomach distension. For that reason, in this patient, denitrogenation was performed during patient's voluntary respiration with 100% oxygen for 5 minutes, and induction was performed without positive pressure ventilation, and one lung ventilation was carried out. Hypoxemia was followed by one lung ventilation because his pulmonary function was moderate obstructive type and his lung was damaged by aspiration of gastric fluid via broncho-gastric fistula. A low level of continuous positive airway pressure (CPAP) has no significant hemodynamic effect and can maintain the patency of nonventilated lung, so hypoxemia induced by one lung ventilation may be reduced. Thus we carried out one lung ventilation with CPAP (10 cmH2O) in nonventilated lung and blocked broncho-gastric fistula with a bronchial blocker for prevention of both regurgitation of gastric fluid and leakage of anesthetic gases. One lung anesthesia was performed without any problem in this case.

BACKGROUND: The SF-6D, derived from the SF-36, is a preference-based instrument measuring health-related quality of life (HRQOL). Using this tool, we measured the HRQOL of persons disabled by stroke dwelling in Gyeongju city and identified factors affecting the HRQOL. METHODS: As of March 2008, 991 persons who had had a stroke and were aged 50 and over were identified on the Gyeongju city disabled registry. Interviewers specifically trained for this face-to-face survey gathered pertinent information including general and clinical characteristics from June to October 2008. In addition, the health status was measured using the Modified Rankin Scale, the Barthel ADL index, and the SF-36. The SF-6D index was derived from the SF-36. We analyzed the known-group construct validity and convergent validity. Finally, we performed multiple regression analyses to identify factors affecting the HRQOL. RESULTS: Of the 991 potential subjects, 498 persons participated in the interviews (response rate: 50.3%). The SF-6D indices for females and those aged 70 and over were lower than indices for males and those aged 60 and less. Correlation coefficients between the Modified Rankin Scale, the Barthel index, and the SF-6D index were relatively high (-0.533 and 0.555, respectively) and statistically significant (P<0.001). Multiple regression analyses showed that sex, age, smoking, alcohol use, comorbidity, the Modified Rankin Scale, and the Barthel index had an effect on the SF-6D index of persons with stroke, and the Barthel index was the most important factor. CONCLUSIONS: Our results indicate that the SF-6D can be a valid tool for evaluating health states of persons disabled by stroke, and functional limitation was the main factor affecting the HRQOL.

Purpose: This study aimed to assess the feasibility of the Apple AirPods Pro with the headphone accommodation feature as a hearing assistive device for patients with mild to moderate hearing loss (HL). Materials and Methods: The study included a total of 35 participants with mild to moderate HL. To determine the degree of HL in the participants, a screening test using pure-tone audiometry was conducted prior to the main tests of functional gain, word recognition score (WRS), and sentence recognition in noisy environments. The study employed two hearing devices: the Bean (a personal sound amplification product, PSAP) and the AirPods Pro. Results: Regarding functional gain, there were no significant differences between the Bean and the AirPods Pro at all frequencies, except 8 kHz. In terms of WRS, both the Bean and the AirPods Pro had higher scores than the unaided condition. In sentence recognition, both the Bean and the AirPods Pro had higher scores than the unaided condition. During real-ear measurement, the Bean demonstrated consistent frequency responses, while the AirPods had a deviation exceeding 10 dB SPL at 6 kHz in the left ear.This deviation was absent for all other frequencies. Conclusion This study shows that the Apple AirPods Pro, with its headphone accommodation feature, performed similarly to a validated PSAP and improved hearing compared to unaided conditions.
