The clinical practice examination (CPX) was introduced in 2010, and the Seoul-Gyeonggi CPX Consortium developed the patient-physician interaction (PPI) assessment tool in 2004. Both institutions use rating scales on classified sections of PPI but differ in their scoring of key components. This study investigated the accuracy of standardized patient scores across rating scales by comparing checklist methods and verified the concurrent validity of two comparable PPI rating tools.
An educational CPX module dyspepsia case was administered to 116 fourth-year medical students at Hanyang University College of Medicine. One experienced standardized patient rated exams using two different PPI scales. She scored checklists composed of 43 items related to the two original PPI scales through video clips of the same students. From these checklists, we calculated Pearson's correlation coefficient.
The correlations of total PPI score between the checklist and rating scale methods were 0.29 for the Korean Medical Licensing Examination (KMLE) tool and 0.30 for the consortium tool. The correlations between the KMLE and consortium tools were 0.74 for checklists and 0.83 for rating scales. In terms of section scores, the consortium tool showed only three significant correlations between the two methods out of seven sections and the KMLE tool showed only two statistically significant correlations out of five sections.
The rating scale and checklist methods exhibited a weak relationship in the PPI assessment, but a high correlation between assessment tools using the same method. However, the current rating scale requires modification by reorganizing key scoring components through factor analysis.

The main aim of this study was to evaluate the achievements of some important goals of Iran's urban family physician plan. This plan was implemented when the country experienced economic instability. We examine whether an economic crisis affects the efficacy of a healthcare program.
We used the household income and expenditures survey data for 2011 (before program implementation) and 2012 (after program implementation). Changes in out-of-pocket payments and healthcare utilization were investigated using the propensity score matching estimator. Furthermore, changes in inequality in these two dimensions were examined.
No changes in out-of-pocket payments and healthcare utilization were found after the implementation of this program; however, inequality in out-of-pocket payments increased during the reform.
The urban family physician program was not implemented completely and many of its fundamental settings were not conducted because of lack of necessary healthcare infrastructure and budget limitations. Family physician programs should be implemented under a strong healthcare infrastructure and favorable economic conditions.

The aim of this study was to determine the association between carotid intima-media thickness (IMT) and newly developed 10-year atherosclerotic cardiovascular disease (ASCVD) risk score.
Participants were 201 Korean adults who underwent carotid ultrasonography at the Health Promotion Center of the Eulji General Hospital. We obtained information about medical history and lifestyle, and conducted laboratory tests. Carotid IMT by B-mode ultrasonography was measured. Carotid injury was considered present when the maximum carotid IMT was ≥0.9 mm or when arteriosclerotic plaques were detected. The 10-year ASCVD risk score was calculated using the 2013 American College of Cardiology/American Heart Association guidelines.
Men had higher 10-year ASCVD risk score than did women (mean±standard deviation: 7.15±6.04 vs. 2.53±3.67, respectively; P<0.001). Ten-year ASCVD risk was significantly correlated with right maximum carotid IMT (r=0.307), left maximum carotid IMT (r=0.230), right mean carotid IMT (r=0.322), and left mean carotid IMT (r=0.264). The group with high 10-year ASCVD risk were at even higher risk of carotid injury than were the group with low 10-year ASCVD risk (odds ratio, 2.201; 95% confidence interval, 1.162-4.1706; P=0.019). Only 10-year ASCVD risk score was significantly associated with carotid injury (odds ratio, 4.104; 95% confidence interval, 1.570-10.729). Variables that were not included in the 10-year ASCVD risk score were not significantly associated with carotid injury.
The findings of this study suggest that 10-year ASCVD risk score is associated with carotid injury.

Neck circumference, as a predicator of obesity, is a well-known risk factor for obstructive sleep apnea and cardiovascular diseases. However, little research exists on neck length associated with these factors. This study explored the association of neck length with sleep and cardiovascular risk factors by measuring midline neck length (MNL) and lateral neck length (LNL).
We examined 240 patients aged 30 to 75 years who visited a health check-up center between January 2012 and July 2012. Patients with depressive disorder or sleep disturbance were excluded from this study. MNL from the upper margin of the hyoid bone to the jugular notch and LNL from the mandibular angle to the mid-portion of the ipsilateral clavicle were measured twice and were adjusted by height to determine their relationship with sleep and cardiovascular disease risk factors.
Habitual snorers had shorter LNL height ratios (P = 0.011), MNL height ratios in men (P = 0.062), and MNL height ratios in women (P = 0.052). Those snoring bad enough to annoy others had shorter MNL height ratios in men (P = 0.083) and women (P = 0.035). Men with objective sleep apnea had longer distances from the mandible to the hyoid bone to the mandible (P = 0.057). Men with metabolic syndrome had significantly shorter LNL height ratios (P = 0.021), and women with diabetes, hyperlipidemia, and metabolic syndrome had shorter MNL height ratios (P < 0.05).
This study shows that a short neck by measuring the MNL is probably associated with snoring. In addition, MNL is related to cardiovascular disease risk factors in women.

The prevalence of gallstone disease is increasing in Korea. Gallstone disease and atherosclerosis share common risk factors. Ultrasonographic carotid intima-media thickness is an independent predictor of atherosclerosis. We measured the carotid intima-media thickness among men who had gallstones to establish the association between atherosclerosis and gallstones.
A total of 330 men who visited the health promotion center of the IS Hallym Hospital from January 2011 to July 2012 were recruited. Both abdomen and carotid ultrasonographies were performed. Demographic, anthropometric, and biochemical data were collected.
The prevalence of gallstones was 6.6%. The carotid intima-media thickness, age, and body mass index were higher in subjects with gallstones (P < 0.05 for all). After Pearson correlation analysis, gallstone, age, body mass index, and fasting blood sugar were significantly associated with carotid intima-media thickness. A statistically positive association between gallstone and carotid intima-media thickness was demonstrated in a multivariate analysis adjusted for age, body mass index, and fasting blood sugar.
Carotid intima-media thickness is higher in male subjects with gallstones, indicating that they are at greater risk for atherosclerosis.

Thoracolumbar junction syndrome is characterized by referred pain which may originate at the thoracolumbar junction, which extends from 12th thoracic vertebra to 2nd lumbar vertebra, due to functional abnormalities. Clinical manifestations include back pain, pseudo-visceral pain and pseudo-pain on the posterior iliac crest, as well as irritable bowel symptoms. During clinical examination, pain can be demonstrated by applying pressure on the facet joints or to the sides of the spinous processes. Radiological studies show only mild and insignificant degenerative changes in most cases. We report a 42-year-old female patient with osteogenesis imperfecta who suffered from chronic low back pain. Under the diagnosis of thoracolumbar junction syndrome, she was treated with an epidural block and a sympathetic nerve block, which improved her symptoms.
