Pseudo-Bartter syndrome is a rare medical disease of the kidney characterized by normal blood pressure, hypokalemic metabolic alkalosis, hyperreninemia and hyperaldosteronism with drug history of diuretics. We report US, CT and MRI findings of a patient with clinically proved pseudo-Bartter syndrome. The patient was a 37-year-old woman with a history of long term ingestion of the diuretics(furosemide) for 20 years. Renal US revealed hyperechoic renal medulla at both kidneys. The resistive index(RI), calculated from the duplex doppler waveform is 0.61. Unenhanced CT revealed faint high attenuation along the medulla. Tl-weighted MRI revealed indistinct corticomedullary differentiation.

PURPOSE: To evaluate the radiologic characteristics of axillary lymph nodes which are found on mediolateral oblique(MLO) view of mammography and to assess their clinical significance. MATERIALS AND METHODS: We retrospectively evaluated 119 cases axillary lymph nodes on MLO view of 410 cases of mammography in 205 patients regarding the size, bilaterality, number, grade of density, presence of central lucency, calcification of lymph nodes and presence of associated parenchymal pathologic lesions in breast. RESULTS: Axillary lymph nodes on MLO view were demonstrated in 119 (29%) among 410 cases. Axillary lymph nodes(112 cases) in cases without breast parenchymal lesions or with benign breast lesions showed; unilaterality in 68 cases(61%), smaller than 1.5cm in 100 cases(89%), lower density than breast parenchyma in 99 cases(88%), presence of central lucency in 99 cases(88%) and calcification in 3 cases(2.7%). Axillary lymph nodes(7 cases)in cases with breast cancer showed small size of less than 1.5cm in 4 cases(57%), absence of central lucency in 7 cases(100%) and iso-to higher density than breast parenchyma in 7 c&ses(100%). CONCLUSION: Axillary lymph nodes noted on MLO view of mammography, more than 1.5cm in diameter, absence of central lucency and iso to higher density than breast parenchyma could be suggested as clinically significant.

We looked for and discussed the changes of curricula of medical course of 31 medical schools during the period of 1984 and 1993. The data used in this study were Educational State Report of Korean Med ical Schools published from Dean Association of Korean Medical Schools in 1984 and 1992-1993. The significant findings were as follows. 1. There were great variability in number of subjects and in time for lecture and exercise in each subject among 31 medical schools. 2. There were a great deal of changes during the period of 1984 and 1993. There were increased tendency in number of subjects and especially block lectures. Schools which had 1-4 subjects vanished in curriculum were most frequent among 22 schools during 9 years. Name of most frequent subjects in block lecture were clinico-patholo gical conference, reproductive medicine, hematology, oncology and cardiology in 1993. 3. Subjects which were transferred to pre-medical program were classified to two groups. One group was traditional basic medical subjects such anatomy, physiology and biochemistry, the other group was newly introduced subjects such as molecular biology and cell biology as basic medical subjects. 4. The data were suggested that long time was needed to stabilized in newly introduced subjects of clinical medicine such as neurology and plastic surgery. Time for lecture and exercise of these subjects shows increasing tendency in schools established before 1978, but decreasing tendency in schools established after 1978.

Purpose:
To compare the clinical effects of Guardcel® (Genewel. Co, Seongnam, Korea) and Nasopore®(Polyganics, Rozenburglaan, Groningen, The Netherlands), two types of absorbable nasal packing materials after endonasal dacryocystorhinostomy.
Methods:
A total of 41 patients (49 eyes) who underwent endonasal dacryocystorhinostomy from March 2017 to January 2019 were studied retrospectively. Twenty seven eyes were packed with Guardcel® and twenty two eyes with Nasopore®. We compared the postoperative anatomical and functional surgical success rates between the groups at 1 week, 1 month, 2 months, and 6 months , as well as the frequency of postoperative complications including bleeding.
Results:
There was no significant difference between the Guardcel® and Nasopore® groups in the postoperative anatomical and functional surgical success rate at 1 week, 1 month, 2 months, or 6 months. Also, there was no significant group difference in the incidence of postoperative complications.
Conclusions
The anatomical and functional surgical success rates and incidence of postoperative complications, including bleeding, synechiae, infection, granuloma, and revision were similar between the Guardcel® and Nasopore® groups. Therefore, Guardcel® can be used safely and effectively as an absorbable nasal packing material in endonasal dacryocystorhinostomy treatment.

Kyphoscoliosis is a disease manifested as lateral curvature of spine and accompanying rotation of the vertebrae, resulting in distortion of rib cage. A curve greater than 40 degrees in considerd to be severe and most likely to be associated with physiologic derangements in cardiac and pulmonary function. Restrictive lung disease and pulmonary hypertension progressing to cor pulmonale are the major causes of mortality in patients with kyphoscoliosis. However, pregnancy itself increases cardiac output and circulating blood volume, and decreases total lung capacity due to enlarged uterus. So tidal volume is increased in pregnant women to compensate. But in kyphoscoliosis patients pulmonary fucntion is already impaired and cardiovascular reserve is minimal. So there is increasing tendency in actue cor pulmonale. Recently we experienced a case of cesarean section in patient with kyphoscoliosis, and observed severe hemodynamic changes especially in pulmonary capillary wedge pressure and cardiac output. And we investigated 7 cases of cesarean section of patients with kyposcoliosis.

Secure fixation is essential for continous epidural catheterization on a long-term-basis. Adhesive tape or surgical knots were commonly used for those patients, but the surgical knot method has a tendency to cause strangulation of catheter. Another invasive technique, subcutaneous tissue tunnelling is more safe than other methods but requires sophisticated technique and time. We employed a simple device using a blood transfusion set for patients who have epidural catheters placed safely on their backs. In 120 patients treated for postoperative and chronic pain by means of this technique, the results were as follows: 1) Five of 120 patients (4.2%) developed backache and pruritus, but there were no instances of respiratory depression, local infection and headache. 2) Nine of 120 patients (7.5%) failed booster-injections, but two cases were due to be non-technical errors. 3) The duration of fixation was 1-3 days in most cases (85%), the longest being for 21 days.

PURPOSE: This study estimated the prevalence of lower urinary tract symptoms (LUTS) in Korean men and the conditions for being diagnosed with or treated for LUTS/benign prostatic hyperplasia (BPH). METHODS: We analyzed cross-sectional data collected from 69,851 Korean men who were 40 years of age or older and had participated in the Korean Community Health Survey performed in 2011. Interviewers performed face-to-face surveys that included sociodemographic questions, the International Prostate Symptom Score (IPSS), and questions regarding whether the subjects had been diagnosed with or treated for LUTS/BPH. We estimated the prevalence of LUTS and assessed whether the subjects had been diagnosed with or treated for LUTS/BPH. RESULTS: Moderate to severe LUTS, storage symptoms, and voiding symptoms increased with age. The IPSS quality of life score was 1.5±0.004 in the mild LUTS group (n=57,701), 3.3±0.01 in the moderate LUTS group (n=9,203), and 4.3±0.02 in the severe LUTS group (n=2,947) (P<0.0001). The prevalence of moderate to severe LUTS in those who had not been diagnosed with LUTS/BPH was 64.5% (7,847 of 12,150), and the prevalence of moderate to severe LUTS in those who had been diagnosed with LUTS/BPH but had not been treated was 23.5% (2,853 of 12,150). CONCLUSIONS: The severity of LUTS in Korean men increased with age, and the IPSS quality of life score increased with the severity of LUTS. Many Korean men with moderate to severe LUTS had not been diagnosed or treated for LUTS/BPH. Socioeconomic conditions played an important role in health-seeking behavior among patients with LUTS/BPH.

Purpose:
The purpose of this study was to investigate whether obesity indicators are mediated in the association between muscle strength and inflammation levels, and further confirm the association between muscle strength level by sex and age and inflammatory levels.
Methods:
In this study, 3,234 adults living in rural areas were surveyed from 2007 to 2015 and the data was finally analyzed on 2,149 adults. To identify that obesity indicators are mediated in relation to the association between relative grip strength and C-reactive protein (CRP) level, odds ratio (OR) and 95% confidence interval (CI) were calculated using logistic regression analysis (p< 0.05).
Results:
As confounding variables were adjusted, the odds ratio for high inflammatory conditions was lower at a high (OR, 0.58; 95% CI, 0.40–0.85) or medium (OR, 0.64; 95% CI, 0.46–0.90) level of relative grip strength than a low level of relative grip strength. However, there were no significant results if the body fat percentage was added for the confounding variable. When the association between relative grip strength and inflammatory conditions was divided by sex, for women, the odds ratio about high inflammatory conditions was gradually decreased as the relative grip level increased (medium level: OR, 0.55; 95% CI, 0.35–0.87; high level: OR, 0.49; 95% CI, 0.30–0.82). The association of relative grip strength with inflammatory conditions was shown differently in age groups.
Conclusion
In conclusion, improvement of muscle strength is a factor that can lower the level of inflammation, and it is important to lower the level of inflammation that can cause cardiovascular disease through resistance exercise differentiated by age and sex.
