The 12th rib syndrome is a disease that causes pain between the upper abdomen and the lower chest. It is assumed that the impinging on the nerves between the ribs causes pain in the lower chest, upper abdomen, and flank. A 74-year-old female patient visited a pain clinic complaining of pain in her back, and left chest wall at a 7 on the 0-10 Numeric Rating scale (NRS). She had a lateral fixation at T12-L2, 6 years earlier. After the operation, she had multiple osteoporotic compression fractures. When the spine was bent, the patient complained about a sharp pain in the left mid-axillary line and radiating pain toward the abdomen. On physical examination, the 10th rib was not felt, and an image of the rib-cage confirmed that the left 10th rib was severed. When applying pressure from the legs to the 9th rib of the patient, pain was reproduced. Therefore, the patient was diagnosed with 9th rib syndrome, and ultrasound-guided 9th and 10th intercostal nerve blocks were performed around the tips of the severed 10th rib. In addition, local anesthetics with triamcinolone were administered into the muscles beneath the 9th rib at the point of the greatest tenderness. The patient's pain was reduced to NRS 2 point. In this case, it is suspected that the patient had a partial resection of the left 10th rib in the past, and subsequent compression fractures at T8 and T9 led to the deformation of the rib cage, causing the tip of the remaining 10th rib to impinge on the 9th intercostal nerves, causing pain.

PURPOSE: To describe the prevalence of vitreoretinal diseases in the Korean population 50 years or older at a health screening center. METHODS: The participants of this study included 11,180 adults 50 years of age and older who visited the Health Promotion Center of Kangbuk Samsung Hospital from January to December 2006. Digital images of non-mydriatic fundus photographs were examined. We calculated the sex- and age-adjusted prevalence of vitreoretinal diseases using the direct standardized method based on the number of resident registrations. RESULTS: The age- and sex-adjusted prevalence of vitreoretinal diseases in Korean adults 50 years of age and older was 9.9%. The prevalence of vitreoretinal diseases significantly increased with age (P=0.000). There was no significant gender difference in the prevalence of vitreoretinal diseases (p=0.553). Age-related macular degeneration was the most common vitreoretinal disease, with an age- and sex-adjusted prevalence of 5.2%. Epiretinal membrane, retinal vein occlusion, and diabetic retinopathy were common vitreoretinal diseases in that order, and the age- and sex-adjusted prevalences were 1.5%, 1.1%, and 0.9%, respectively. CONCLUSIONS: The prevalence of vitreoretinal diseases in a screened Korean population 50 years and older was 9.9%. Vitreoretinal diseases are a major ophthalmic problem in Korea. As the Korean population continues to age and the prevalence of diabetes increases, further investigations about the epidemiology and prevention of vitreoretinal diseases are needed.

PURPOSE: To assess the diagnostic efficacy of magnetic resonance (MR) imaging in the detection of a vertebralartery injury occurring from major cervical spine trauma. MATERIALS AND METHODS: Conventional MR findings of 63patients and 63 control subjects were compared to detect a possible change in the vertebral arteries resulted fromtrauma. Plain films, CT and clinical records were also reviewed to correlate the degree of cervical spine injurywith vascular change. RESULTS: Nine cases of absent flow signals in vessel lumen were observed in eight patientsand one was observed in the control group. Patients more frequently demonstrated other abnormalities such asintraluminal linear signals (n=3) or focal luminal narrowing (n=9) but there was no statistical significance. There was a close relationship between degree of cord damage and occlusion of the vertebral artery. CONCLUSION: Conventional MR imaging is useful in the detection of vertebral artery occlusion resulting from cervical spinetrauma.

Purpose: To confirm that the phaco chop method using an illuminated chopper (iChopper; Oculight, Seongnam, Korea) can reduce cataract surgery complications, and that even beginners can safely and effectively perform phaco chop. Methods: We retrospectively analyzed the medical records of the first 30 phaco chop cases using illuminated chopper of four cataract surgeons. Four ophthalmologists had a variety of empirical backgrounds, from those who have experienced more than 10,000 cataract surgery, to beginners who have experienced 20 cataract surgery. Results: Of the total 120 eyes, two eyes (1.67%) had posterior capsule rupture. The chopping method was changed from phaco chop to stop and chop in three eyes (2.5%) including one eye with brown cataract with pseudoexofoliation syndrome and two eyes with nuclear opacity grade ≥5. Conclusions The rates of posterior capsule rupture of phaco chop using an illuminated chopper were very low in four surgeons with various experiences and who became proficient shortly in phaco chop.

Background/Aims: In Korea, changes in the prevalence of irritable bowel syndrome (IBS) after the Rome IV update have not been extensively studied.The aim of this study is to compare the prevalence and psychosocial risk factors of IBS according to Rome III and Rome IV criteria in medical and nursing students. Methods: From August 13, 2021 to October 22, 2021, participants were enrolled and surveyed online. The survey includes general and specific questions for disease diagnosis and regarding participants’ social and psychological characteristics using the 36-item short form survey, the Brief Encounter Psychosocial Instrument-Korean version, and the Hospital Anxiety and Depression Scale. Results: In total, 338 medical students and 102 nursing students completed the survey. IBS was diagnosed in 78 students (17.7%) using Rome III criteria and in 51 students (11.6%) using Rome IV criteria. Significant differences in physical functioning score and severity score were observed between patients diagnosed using Rome IV criteria and patients diagnosed using Rome III criteria. Multiple logistic regression revealed that severity score (adjusted odds ratio = 1.01; 95% confidence interval: 1.00-1.21; P = 0.022) is the only predictor of IBS that differentiates Rome IV criteria from Rome III criteria. Conclusions Even after updating the Rome IV diagnostic criteria, the prevalence of IBS in medical and nursing students in Korea remained high.Patients who met the Rome IV criteria had more severe symptoms and lower quality of life than patients who met the Rome III criteria.

BACKGROUND: The purpose of this study was to examine the sensitivity and specificity of ECG as a tool for detecting echocardiographically defined LVH in a population-based sample and to examine the impact of a variety of factors that affect the sensitivity and specificity of ECG for detection of LVH. METHODS: A total of 1,130 subjects who received a thorough medical checkup for cardiologic department voluntarily were selected. The subjects were examined using M-mode echocardiography and standard 12-lead ECG. The chi-square test was used to test for differences in sensitivity and specificity of ECG for echocardiographically defined LVH. Cochran-Mantel-Haenszel statistic was used to adjust for sex, age, and obesity and to test the association between cigarette smoking, amount of alcohol, exercise, hypertension, diabetes mellitus (DM) and sensitivity and specificity of ECG. RESULTS: Echocardiographic LVH was detected in 434 (38.4%) and electrocardiographic features of LVH were present in 146 (12.9%). ECG for diagnosis of LVH showed sensitivity of 20.0%, specificity of 91.5%, and diagnostic accuracy of 64.1%. Sensitivity of ECG for LVH was higher in persons with obesity (P=.04) or hypertension (P=.04). Specificity of ECG for LVH was lower in persons with hypertension (P=.003) CONCLUSION: ECG has a low sensitivity and a high specificity for echocardiographically defined LVH. Attention must be paid to carefully interpret ECG for diagnosis of LVH in persons with obesity or hypertension, because the rate of false positives and negatives can be increased.

PURPOSE: The Korean Society of Radiation Oncologists (KOSRO) conducted the Patterns of Care Study (PCS) of radiotherapy (RT) for spine metastases in 2009. The current study was conducted to investigate current practice patterns and compare them with the results of the PCS. MATERIALS AND METHODS: The survey questionnaire was composed of 10 questions regarding general information and seven questions for each of two clinical scenarios. RESULTS: Fifty-four members of the KOSRO answered at least one question on the web-based questionnaire. The yearly number of patients treated who underwent palliative spine RT was greater than 200 in 14 (25.9%), 51 to 100 in 13 (24.1%), and 31 to 50 in 11 respondents (20.4%). Scenario 1 described a patient presenting with cord compressive spine metastasis in multiple bones and liver metastasis from non-small cell lung cancer. Thirty gray (Gy) in 10 fractions was chosen by 35 respondents (64.8%). Scenario 2 described a case of a single spine metastasis without progression after targeted therapy. Thirty Gy in 10 fractions was chosen by 19 respondents (35.2%), and a single fraction or less than four fractions of stereotactic ablative radiotherapy (SABR) were selected by 18 respondents (33.3%). When compared with the 2009 PCS, practice patterns of Korean radiation oncologists had not changed significantly over 5 years, except that SABR emerged as a new treatment modality in the selected population. CONCLUSION: The 2014 PCS demonstrated that multiple fraction RT is still preferred in a considerable proportion of Korean radiation oncologists.
