Background: This study aimed to investigate the association between type 2 diabetes mellitus (T2DM) and shoulder adhesive capsulitis (AC) using a large-scale, nationwide, population-based cohort in the Republic of Korea. Methods: A total of 3,471,745 subjects aged over 20 years who underwent a National Health Insurance Service medical checkup between 2009 and 2010 were included in this study, and followed from the date of their medical checkup to the end of 2018. Subjects were classified into the following four groups based on the presence of dysglycemia and history of diabetes medication: normal, prediabetes, newly diagnosed T2DM (new-T2DM), and T2DM (claim history for antidiabetic medication). The endpoint was new-onset AC during follow-up. The incidence rates (IRs) in 1,000 person-years and hazard ratios (HRs) of AC for each group were analyzed using Cox proportional hazard regression models. Results: The IRs of AC were 9.453 (normal), 11.912 (prediabetes), 14.933 (new-T2DM), and 24.3761 (T2DM). The adjusted HRs of AC in the prediabetes, new-T2DM, and T2DM groups were 1.084 (95% confidence interval [CI], 1.075 to 1.094), 1.312 (95% CI, 1.287 to 1.337), and 1.473 (95% CI, 1.452 to 1.494) compared to the normal group, respectively. This secular trend of the HRs of AC according to T2DM status was statistically significant (P<0.0001). Conclusion This large-scale, longitudinal, nationwide, population-based cohort study of 3,471,745 subjects confirmed that the risk of AC increases in prediabetic subjects and is associated with T2DM status.

Craniocerebral gunshot injuries (CGIs) are extremely seldom happened in Korea because possession of individual firearm is illegal. So, CGIs are rarely encountered by Korean neurosurgeons or Korean trauma surgeons, though in other developing countries or Unites states of America their cases are indefatigably increasing. Management goal should focus on early aggressive, vigorous resuscitation. The treatments consist of immediate life salvage through correction of coagulopathy, intracranial decompression, prevention of infection and preservation of nervous tissue. There have been few studies involving penetrating CGIs in Korea. Here we present a case of penetrating gunshot wound in Korea. We present a 58-year-old man who was unintentionally shot by his colleague with a shotgun. The patients underwent computed tomography (CT) for assessment of intracranial injury. The bullet passed through the left parietal bone and right lateral ventricle and exited through the posterior auricular right temporal bone. After CT scan, he arrested and the cardiopulmonary resuscitation was conducted immediately. But we were unable to resuscitate him. This case report underscores the importance of the initial clinical exam and CT studies along with adequate resuscitation to make the appropriate management decision. Physicians should be familiar with the various injury patterns and imaging findings which are poor prognostic indicators.

Non-traumatic, spontaneous urinary bladder rupture is a rare complication of urethral stricture. Furthermore, its symptoms are often nonspecific, and misdiagnosis is common. The authors experienced a case of urethral stricture with spontaneous bladder rupture and bilateral hydronephrosis, mimicking obstructive uropathy attributed to cancer metastasis. A 55-year-old woman was admitted with abdominal pain and distension, oliguria, and an elevated serum creatinine level. She had undergone radical hysterectomy for uterine cervical cancer and received post-operative concurrent chemoradiation therapy 13 years previously. Non-contrast enhanced computed tomography showed massive ascites and bilateral hydronephrosis. The initial diagnosis was acute kidney injury due to obstructive uropathy caused by malignant disease. After improvement of her renal function by bilateral percutaneous nephrostomy catheterization, contrast-enhanced computed tomography and a cytologic examination of ascites showed no evidence of malignancy. However, during retrograde pyelography, a severe urethral stricture was found, and subsequent cystography showed leakage of contrast into the peritoneal cavity and cystoscopy revealed a defect of the posterior bladder wall. After urethral dilatation and primary closure of the bladder wall, acute kidney injury and ascites were resolved.

BACKGROUND/AIMS: Esophageal cancer and dysplasia are relatively rare in Korea, compared to other Far Eastern countries. So, the feasibility and safety of endoscopic treatments for these diseases is not well established in Korea. This study aimed to assess the technical feasibility, safety and the clinical outcomes of endoscopic treatment for esophageal epithelial lesions. MATERIALS AND METHODS: Between April 2005 and March 2013, 25 esophageal epithelial lesions from 22 patients were treated with endoscopic treatment such as endoscopic submucosal dissection or endoscopic mucosal resection. RESULTS: Of the 25 lesions, 11 lesions were treated with endoscopic submucosal dissection (ESD) (ESD group) and 14 lesions with endoscopic mucosal resection (EMR group). In the ESD group, the diagnosis was squamous cell carcinoma in 7 patients (64%), high grade dysplasia in 3 patients (27%), and low grade dysplasia in 1 patient (9%). In the EMR group, thediagnosis was squamous cell carcinoma in 8 patients (57%), high grade dysplasia in 2 patients (14%), and low grade dysplasia in 4 patients (29%). En bloc resection rates were 100% in ESD and 42.9% in EMR, respectively. For the median 12 months follow up period, there was no recurrence in the ESD group. However, there were three recurrences in the EMR group. CONCLUSIONS: Endoscopic treatment for esophageal epithelial lesions is safe and feasible therapeutic modalities. Especially, ESD can provide higher rate of en bloc and curative resection for early esophageal cancer and dysplasia.

BACKGROUND/AIMS: Cardiovascular complications are commonly seen in patients with chronic kidney disease (CKD). Recently, the prevalence of left ventricular diastolic dysfunction (LVDD) has increased, and the importance of LVDD has emerged in patients with CKD. The objectives of this study were to identify diagnostic criteria for LVDD related to ischemic heart disease (IHD) and evaluate the prognostic impact of diastolic dysfunction in patients with CKD. METHODS: A total of 71 patients with CKD who were evaluated between January 2005 and May 2010 were included in this study. These patients were evaluated by conventional echocardiography and tissue Doppler imaging (TDI) for diastolic dysfunction. RESULTS: Diagnostic cutoff values for LVDD related to IHD were E/E' = 15.55 (sensitivity: 100%, specificity: 64.7%, p = 0.005) and E/A = 0.79 (sensitivity: 84.6%, specificity: 55.9%, p = 0.006). Group I consisted of 19 patients with an E/E' > 15.55 and E/A > 0.79. Group II consisted of the remaining patients. Factors contributing to LVDD were age, history of ischemic heart disease, anemia, and high low-density lipoprotein (LDL) level. Factors contributing to IHD were LVDD, smoking, high LDL level, and high parathyroid hormone (PTH) level. The disease-free survival for IHD was significantly lower in group I compared to group II (p = 0.001). However, there was no significant difference in overall survival between groups I and II (p = 0.177). CONCLUSIONS: Our study showed that moderate LVDD (E/E' > 15.55 and E/A > 0.79) in patients with CKD is positively associated with IHD.

A 42-year-old male was hospitalized with abdominal pain, dyspnea, and turbid peritoneal fluid. He was diagnosed with hypertension, diabetes and started continuous ambulatory peritoneal dialysis (CAPD) 11 months ago. He was treated with intraperitoneal cefazolin and ceftazidime, and then white blood cell counts of dialysate decreased. Incidentally, liver abscess was found in chest CT performed for the evaluation of dyspnea, and patient was febrile persistently. So percutaneous abscess drainage was done by pigtail catheter. We changed the antibiotics to ceftriaxone and metronidazole, and hemodialysis was started. Klebsiella pneumoniae was cultured from peritoneal fluid and blood simultaneously. We concluded that liver abscess is a primary cause of CAPD peritonitis.

The rate of dependence among ever-users of a drug indicates the risk of developing dependence once an individual has been exposed to the drug. This is the first study to investigate 12-month tobacco dependence (TD) among ever-smokers in a community-based population. Analyses were based on two national studies of representative samples aged 18-64 in 1984 (n=5,025) and in 2001 (n=6,275), conducted with household visits and face-to-face interviews. The rates of 12-month TD among ever-smokers in men showed no significant difference between 51.6% in 1984 and 50.6% in 2001. On the contrary, the rates in women significantly increased from 33.3% in 1984 to 52.8% in 2001. After adjusting for the sociodemographic variables, 'male gender' was significantly associated with 12-month TD among eversmokers in 1984, but not in 2001. 'Unmarried' was significantly associated in 2001 but not in 1984. 'Alcohol dependence' was the only psychiatric disorder associated with 12-month TD in both study years. In conclusion, 12-month TD was found in about 50% of ever-smokers, and gender differences between the rates of 12-month TD which was observed in 1984 disappeared in 2001. Individuals with 12-month TD showed higher comorbidity with alcohol dependence than ever-smokers without TD.

PURPOSE: Using proteomic analysis, this study was performed to see the characteristics of proteins expression in the muscles of spastic cerebral palsy patients. MATERIALS AND METHODS: We studied twelve specimens from six patients with spastic cerebral palsy, three patients with myelomeningocele, and three normal people who underwent orthopaedic surgeries due to trauma. We studied the extracted proteins showing differences in the two-dimensional electrophoresis, and the prominent thirteen proteins were re-evaluated by proteomics and the reverse transcriptional polymerase chain reaction, which was to clarify the relationship between gene and protein expression. RESULTS: Among fifteen proteins, six proteins were found to be higher in normal people, and nine were found to be higher in the groups of patients by spot histogram. The results of proteomic analysis with MALDI-TOF for fifteen proteins showed that the expression of DJ-1 was related to cerebral palsy. CONCLUSION: This study shows that strong expression of DJ-1 is related to spasticity and cerebral palsy. We showed for the first time the possibility of any relationship between spastic condition and DJ-1 expression.

BACKGROUND: Acid-base imbalances are common in critically ill patients; however, the incidence of acid-base imbalances in the medical intensive care units has not been fully determined. In this study, we investigated the incidence and the type of acid-base imbalances in critically ill patients and we assessed which variables were associated with the patients' outcome. METHODS: One hundred eighty-seven patients (122 men, age: 61.2+/-12.8 years) were enrolled. All the patients were admitted to the medical intensive care unit between January 2005 and December 2005. All the data sets included simultaneous measurements of an arterial blood gas with base excess, the serum electrolytes, the anion gap and the APACHE II scores. RESULTS: The mortality rate was 56.7%. The incidence of acid-base imbalances was as follows: 25.1% were single disorders that existed with only a single primary acid-base imbalance, 48.7% were double disorders, 13.4% were triple disorders and 12.8% were normal (no disorders). The incidence of metabolic acidosis was 57.8% and the mortality rate was not different according to the type of acid-base imbalances. There were significant differences between the nonsurvivors and survivors according to the pH (7.34 vs. 7.41, respectively), HCO(-)3 (20.68 mmol/L vs. 25.90 mmol/L, respectively), ECF base excess (-5.19 vs. 1.19, respectively), the anion gap (18.57 mmol/L vs. 13.77 mmol/L, respectively), the corrected anion gap (23.63 mmol/L vs. 17.96 mmol/L, respectively), the serum albumin (2.37 g/dL vs. 2.74 g/dL, respectively), and the APACHE II scores (20.7 vs 17.2, respectively). However, on the Cox proportional hazard regression analysis, only the APAHCE II scores affected the patients' outcome. CONCLUSIONS: There were diverse acid-base imbalances in the critically ill patients and the incidence of metabolic acidosis was highest among the acid-base imbalances. The best predictor of the patients' outcome was the APACHE II scores.

PURPOSE: The aim of this study is to investigate incidence and related affecting factors on bacterial colonization and bacteremia of cuffed & tunnelled dialysis catheter and noncuffed dialysis catheter. METHODS: This study was performed retrospectively through review of medical records from May 2005 to May 2006. 102 central venous catheters for hemodialysis were analyzed: cuffed & tunnelled dialysis catheter (n=32, group P); noncuffed dialysis catheter (n=70, group G). RESULTS: There was no difference between group P (15.6%) and group G (15.7%) in cumulative incidence of catheter colonization. However, in terms of risk for colonization with time, incidence density of group P was lower than group G (group P, 1.17/1,000 catheter days; group G, 12.97/1,000 catheter days). In the subgroup analysis of group G, incidence density of internal jugular vein group was lower than femoral vein group (internal jugular vein catheter, 7.54/1,000 catheter days; femoral vein catheter, 32.43/1,000 catheter days). CONCLUSION: The risk of catheter colonization turned out higher in noncuffed dialysis catheter than in cuffed & tunnelled dialysis catheter. Therefore, more delicate antiseptic cares for dialysis catheter were needed in case of emergency. Additionally, permanent vascular access should be placed earlier to avoid insertion of temporary dialysis catheter in end-stage renal disease.
