Methods: In this retrospective study, we reviewed 37 IL and 34 CL approaches. Postoperative magnetic resonance imaging of the segment involved was carried out on the same day as the operation for comparison with preoperative imaging. Radiological assessments of recess angle, recess height, facet length, and recess dural sac diameters were compared. In addition, pre- and postoperative Visual Analog Scale (VAS) pain scores for the lower limb were analyzed. Results: For IL versus CL approaches, we observed statistical differences in the postoperative recess angle (36.0° vs. 43.7°), recess height (4.27 vs. 5.06 mm), and the dural sac expansion ratio for recess diameter (1.54 vs. 2.17). There was better preservation of facet length in the CL approach than in the IL approach (91.9% vs. 83.7%). There was no difference in VAS improvement between the groups (69.3% vs. 63.6%). Conclusions Unilateral biportal decompression via the CL interlaminar approach may offer better lateral recess clearance and facet preservation than can be achieved via the IL approach. Larger-scale studies are needed for better delineation and for correlation of radiological features with clinical manifestations.

Background: Although numerous studies have indicated that lower levels of physical activity correlate with a higher risk of depression, an association between the type of physical activity and depression has not been identified in Korea. This study aimed to examine whether the type and intensity of physical activity are associated with depression in Korean adults. Methods: This cross-sectional study used data from the Korea National Health and Nutrition Examination Survey (KNHANES). A total of 11,679 individuals were analyzed using multiple logistic regression analyses to identify any association between the type of physical activity and depressive disorders in the sample subjects. Results: Measured weekly in units of energy expenditure, known as metabolic equivalents (METs), the amount of work-related physical activity was higher in individuals with depression according to the Patient Health Questionnaire- 9 than the participants without depression (386.7 vs. 206.7 MET-min/wk, P=0.01). Those diagnosed with depression tended to engage in less recreational activity per week (143.7 vs. 316.3 MET-min/wk, P<0.001) than those without depression. After controlling for covariates, the risk of depression among all participants was 1.012 times higher with a 100-unit increase in total work-related activity measured in METs (95% confidence interval [CI], 1.006–1.017; P<0.001) and 0.962 times lower with a 100-unit increase in total leisure activity measured in METs (95% CI, 0.937–0.987; P=0.003). Conclusion Different types of physical activity were shown to be differently associated with depressive disorders in Korean adults. This study might guide in reducing work-related physical activity and increasing leisure activity to prevent the occurrence of depression.

PURPOSE: Clinical performance examination (CPX) has been used to assess clinical competence as one step of medical license examination. Initial CPX score of the fourth year medical student is important since it indicates how to prepare successfully for the final examination. This study was conducted to assess the predictors of CPX scores of the fourth year medical students who completed core clinical clerkship. METHODS: One hundred eleven fourth year medical students took a formative CPX in February. The score was compared with the scores of cognitive area and those of behavioral area which students had acquired in the past. We analyzed the correlation between the scores and determined the predictors of the fourth year CPX score. RESULTS: The fourth year CPX score showed stronger correlation with the scores of behavioral area than those of cognitive area. The significant predictors of fourth year CPX score included third year simple procedure exam score and third year clerkship CPX score. The risk factors for low fourth year CPX score included second year patient-physician interaction (PPI) score and third year CPX score after adjusted for age, sex, and school type. The risk factors of being selected as a low PPI score group of fourth year included low PPI scores of first, second, and third year exams. CONCLUSION: Our study highlights importance of educational balance between cognitive and behavioral areas. To improve clinical competence of final year medical students, clinical interview training using standardized patient with other modules is to be enhanced and initiated early in the medical curriculum.

Epithelioid hemangioendothelioma (EH) is a rate pulmonary vascular malignancy. Clinically, EH has been considered as an indolent, generally non-aggressive tumor. We report a case of EH which was confirmed by open lung biopsy. A 34-year-old woman was admitted for further evaluation of multiple small (less than 2cm in size) nodules, incidentally detected on screening chest radiograph. The chest CT showed multiple, relatively well-marginated, variable sized nodules at both whole lung. Transbronchial lung biopsy and transthoracic needle aspiration were nondiagnostic and open lung biopsy was performed from right middle lobe of lung. On light-microscopic examination, the nodules were composed of a poorly cellular hyaline core and a more cellular peripheral zone which extended into air space in a micropolypoid fashion and obliterated blood vessels. The tumor cells at the peripheral zone had intracytoplasmic vacuoles which suggested primitive, vascular differentiation. Immuno-histochemical study revealed the cellular area which gave positive reaction to factor VIII-related antigen. She received no specific therapy after open lung biopsy and chest X-ray films had showed no change for about two years.

Background: Many studies have reported that dog ownership is effective in encouraging physical activity. However, the association between living with a dog and enhanced physical activity has not been clearly verified. Thus, this study aimed to investigate the effects of dog ownership on the amount of physical activity in a representative sample of Korean adults. Methods: This cross-sectional study administered the International Physical Activity Questionnaire (IPAQ) to 1,299 individuals who visited the international healthcare center of one hospital in Seoul, Korea, between August and December in 2018. Based on responses to the IPAQ survey, the amount and duration of physical activity was calculated to analyze relationships with dog ownership. Results: The total amount (P=0.02) and duration of physical activity (P=0.02) and the duration of vigorous-intensity physical activity (P=0.04) were significantly higher among dog owners than non-dog owners. The duration of daily physical activity increased with dog ownership by 18.6 minutes (P=0.01). A comparison of dog owners according to whether they walked with their dogs revealed that dog walking had no significant effect on the amount and duration of physical activity, inactivity, or health-enhancing physical activity status. There was a sex-specific association between dog ownership and total duration of physical activity in females. Conclusion The duration of physical activity increased by dog ownership. However, the higher levels of physical activity among dog owners may not necessarily be explained by dog ownership or walking with dogs. This outcome suggests that raising a dog can help promote physical activity.

Background: This study aimed to examine the relationship between patient experience and medication compliance of patients with dyslipidemia.
Methods: Based on data from the Korea National Health and Nutrition Examination Survey in 2015, the study examined 764 patients treated with dyslipidemia medication. Subjects who responded to the question “Do you currently take medication to lower your blood cholesterol?” with “daily taking” were categorized as the compliant group, and the remaining subjects were classified under the non-compliant group. The patient experience survey included four indicators, in which subjects were divided into groups with a positive and negative patient experience. Data on sociodemographic factors, health-related behaviors, and self-reported comorbid conditions were also collected.
Results: After adjusting the variables, the group with a positive response for the patient experience indicator “doctor spends enough time with the patient during consultation” was 1.89 times more compliant than the group with a negative response (95% confidence interval [CI], 1.03–3.48; P=0.04). For the indicator “doctor provides easy-to-understand explanations,” the group that showed a positive response was 2.74 times more compliant than the group with a negative response (95% CI, 1.39–5.39; P=0.004). For the indicator “doctor involves patients in decisions about care or treatment,” the group that showed a positive response was 2.07 times more compliant than the group with a negative response (95% CI, 1.02–4.22; P=0.04). However, for the indicator “doctor provides the patient a chance to ask questions about treatment,” positive patient experience had no significant association with medication compliance (95% CI, 0.77–2.36; P=0.30).
Conclusion Building a good doctor-patient relationship with positive patient experiences can result in better outcomes for patient care through high medication compliance.
