Correlations between metabolic syndrome, serologic factors, and gallstones.

[Purpose] This study investigated the serologic factors associated with metabolic syndrome and gallstones. [Subjects and Methods] The study evaluated subjects who visited a health promotion center in Seoul from March 2, 2013 to February 28, 2014, and had undergone abdominal ultrasonography. Height, weight, and blood pressure were measured.

Risk factors for fatigue and stress among Korean police officers.

[Purpose] This study investigated factors that affect the health of police officers by analyzing job stress, psychosocial stress, and fatigue faced by police officers in order to provide basic data for the efficient management of police officers and future comparative research. [Subjects and Methods] Police officers admitted to the National Police Hospital from March to May 2013 were surveyed to investigate their degree of stress. The questionnaire consisted of 4 areas related to patient characteristics: general and demographic characteristics factors, job stress, psychosocial stress, and fatigue.

Blood levels related to the Z-score of bone mineral density in young males and females.

[Purpose] The purpose of this study was to investigate the blood levels related to the bone mineral density by using the dual energy X-ray absorption for females before menopause and males younger than 50 years old. [Subjects and Methods] Between August 1, and September 15, 2013, the Z-score was measured in females before menopause and males younger than 50 years old using a bone mineral density measuring instrument. After the measurement, the subjects were classified into two groups, that is, the below expectations and within expectations groups.

Risk factors for musculoskeletal symptoms among Korean radiation workers.

The first aim of this study was to determine the prevalence of musculoskeletal symptoms. The second aim was to study the association between musculoskeletal symptoms and factors in radiation workers from the active lists of clinics and hospitals and then to provide basic data for a systematic and effective resource management of radiation workers' musculoskeletal problems in the future. A questionnaire survey was conducted on radiation workers in clinics, general hospitals, and Dong-A university hospitals around the Korean city Buscan from July 10 to 31, 2011.

Measurement of T2 value by using 3.0T MRI for patient with ankle arthritis.

This study intended to evaluate shape of ankle joint cartilage and damage to the ankle joint cartilage by measuring changes in T2 value of cartilage of healthy people without ankle arthritis and patients with ankle arthritis. The multi-echo technique was used for 20 healthy persons who had no ankle arthritis in the past or in the present clinically and 20 patients who were examined to have ankle arthritis in order to obtain T2 map image of knee joint cartilage. We divided the talotibial joint into medial position, middle position and lateral position to calculate the mean values of T2 in 18 spots that included anterior part, middle part and posterior part of cartilage of neck bone and ankle bone.

Exiting root injury in transforaminal endoscopic discectomy: preoperative image considerations for safety.

Purpose: To evaluate the clinical and radiological risk factors for exiting root injuries during transforaminal endoscopic discectomy.

Methods: We retrospectively examined cohort data from 233 patients who underwent percutaneous endoscopic lumbar discectomy for lumbar disc herniation between January 1st, 2010 and December 31st, 2011. We divided the patients into the two groups: those who presented a postoperative exiting root injury, such as postoperative dysesthesia or motor weakness (Group A, n = 20), and those who did not suffer from a root injury (Group B, n = 213).

Associations between sympathetic activity, plasma concentrations of renin, aldosterone, and parathyroid hormone, and the degree of intractability of blood pressure control in modialysis patients.

This study was designed to examine how such factors as hemodialysis parameters, body mass index, renin and aldosterone concentrations, sympathetic nervous activity, and parathyroid hormone concentrations are associated with the control of hypertension in hemodialysis patients. Hemodialysis patients (n=114) were grouped into four categories. Group 1 had normal BP without antihypertensive medication.

Relationship between serum prostate-specific antigen levels and body mass index in healthy younger men.

Objectives: To understand further the physiologic characteristics of serum prostate-specific antigen (PSA) concentrations in healthy younger men.

Methods: A total of 2032 men, 20 to 39 years old, who visited our hospital for a routine health checkup were entered into the study. Pearson correlation coefficients were determined to evaluate the association between serum PSA and clinical parameters.

Computerized physician order entry and electronic medical record systems in Korean teaching and general hospitals: results of a 2004 survey.

Objective: To determine the availability of computerized physician order entry (CPOE) and electronic medical record (EMR) systems in teaching and general hospitals in the Republic of Korea.

Design: A combined mail and telephone survey of 283 hospitals.

Measurements: The surveys assessed the availability of CPOE and EMRs in the hospitals, as well as inducement, participation, and saturation regarding CPOE use by physicians.

Influence of age, anthropometry, and hepatic and renal function on serum prostate-specific antigen levels in healthy middle-age men.

Objectives: To test the hypothesis of a causal relationship between clinical parameters, including age, anthropometry, and hepatic or renal function tests and serum prostate-specific antigen (PSA) levels and to determine the predictors of high serum PSA concentrations in healthy middle-age men.

Methods: Between January 1999 and December 2000, 6005 healthy men 40 to 59 years old who visited our hospital for a routine health checkup were entered into the study. The association between the clinical parameters and a high serum PSA level (greater than 2.

Distribution of serum prostate-specific antigen in healthy Korean men: influence of ethnicity.

Objectives: To evaluate the normal distribution of serum prostate-specific antigen (PSA) levels in healthy Korean men. The subjects included men younger than 40 years of age, because information on serum PSA levels in younger men is scarce.

Methods: Between January 1997 and December 1998, the serum PSA levels of the subjects who visited our hospital for a routine health checkup were determined.
