BACKGROUND/AIMS: Because of rarity, role of chemotherapy of bladder adenocarcinoma are still unidentified. Therefore, we performed a retrospective analysis of the clinical features and chemotherapy outcomes of bladder adenocarcinoma. METHODS: Eligible patients for this retrospective analysis were initially diagnosed with bladder adenocarcinoma and presented with a clinically no other primary site of origin. The collected data included age, gender, performance status, stage, hemoglobin, albumin, initial date of diagnosis, treatment modality utilized, response to treatment, presence of relapse, last status of patient, and last date of follow-up. RESULTS: We retrospectively reviewed 29 patients, who were treated with chemotherapy for bladder adenocarcinoma at 10 Korean medical institutions from 2004 to 2014. The median age of patients was 58 years (range, 17 to 78) and 51.7% of the patients were female. Urachal adenocarcinoma was identified in 15 patients. Of 27 symptomatic patients, 22 experienced gross hematuria. Twelve patients were treated with 5-f luorouracil based chemotherapy, five were gemcitabine based, three were taxane and others. Thirteen of them achieved complete response (10.3%) or partial response (34.5%). Median progression-free survival (PFS) and overall survival (OS) for all patients were 10.6 months (95% confidence interval [CI], 9.5 to 11.6) and 24.5 months (95% CI, 1.2 to 47.8), respectively. The cases of urachal adenocarcinoma exhibited worse tendency in PFS and OS (p = 0.024 and p = 0.046, respectively). CONCLUSIONS: Even though bladder adenocarcinoma had been observed moderate effectiveness to chemotherapy, bladder adenocarcinoma is a highly aggressive form of bladder cancer. PFS and OS were short especially in urachal carcinoma.

BACKGROUND: In cirrhotic patients, left ventricular diastolic dysfunction is associated with poor outcomes. Diastolic wall strain (DWS) is a new index of left ventricular diastolic function that correlates with the myocardial stiffness. In this study, we aimed to determine whether DWS calculated from preoperative transthoracic echocardiography can predict the survival of liver transplantation recipients. METHODS: A total of 981 patients who underwent liver transplantation were enrolled. We collected the clinical, laboratory and echocardiographic data retrospectively. The left ventricular posterior wall thickness at end-systole (LVPWs) and end-diastole (LVPWd) were measured using M-mode imaging. DWS was calculated as follows: DWS = (LVPWs – LVPWd) / LVPWs. As previously reported, DWS ≤ 0.33 was defined as low DWS and DWS > 0.33 was defined as normal DWS. The primary outcome of this study was 2-years survival after liver transplantation. RESULTS: The 2-years mortality rate following liver transplantation was higher in low DWS group than normal DWS group (14.6% vs.10.0%, P = 0.038). In univariate Cox regression analysis, age, model for end-stage liver disease score, Child-Turcotte-Pugh score, creatinine, b-type natriuretic peptide, heart rate, left ventricular end-diastolic volume index, left ventricular stroke volume index, left ventricular ejection fraction, E/A ratio, e′, E/e′ ratio, and DWS were associated with 2-years survival after liver transplantation. In multivariate Cox regression analysis, DWS was an independent predictor of 2-years survival after adjusting significant univariate covariates. CONCLUSIONS: This study results indicated that the DWS is an independent prognostic predictor in liver transplantation recipients.

BACKGROUND/AIMS: In spite of increased concerns about the overlaps among the various functional gastrointestinal disorders (FGIDs), studies for the overlap between constipation and other common FGIDs are rare. Therefore, we investigated the patterns of overlaps between constipation and other common FGIDs. METHODS: This study was designed as a prospective nationwide multi-center questionnaire study using Rome III questionnaires for functional dyspepsia (FD), irritable bowel syndrome (IBS), and functional constipation (FC), as well as various questionnaires about patients’ information, degree of symptoms, and quality of life. For the evaluation of gastroesophageal reflux disease (GERD), GERD-Q was used. RESULTS: From 19 centers, 759 patients with constipation were enrolled. The proportions of FC and IBS subtypes of constipation (IBS-C) were 59.4% and 40.6%, respectively. Among them, 492 (64.8%) showed no overlap. One hundred and thirty-six patients (17.9%) presented overlapping GERD, and 80 patients (10.5%) presented overlapping FD. Fifty one (6.7%) of patients were overlapped by both GERD and FD. Coincidental herniated nucleus pulposus (HNP) (P = 0.026) or pulmonary diseases (P = 0.034), reduced fiber intake (P = 0.013), and laxative use (P < 0.001) independently affected the rate of overlaps. These overlapping conditions negatively affected the constipation-associated quality of life, general quality of life, and degree of constipation. CONCLUSIONS: The overlap of GERD or FD was common in patients with constipation. Coincidental HNP or pulmonary diseases, reduced fiber intake, and laxatives use were found to be independent associated factors for overlapping common FGIDs in Korean patients with constipation.

BACKGROUND/AIMS: Treatment of gastric neuroendocrine tumors is determined by type and size of the lesion. This study aimed to compare the long-term efficacy of observation and endoscopic resection for type 1 gastric neuroendocrine tumors without metastasis. MATERIALS AND METHODS: Among the 223 cases of gastric neuroendocrine tumors diagnosed between January 1996 and December 2011, 104 cases were type 1 gastric neuroendocrine tumors. Sixty-seven patients were treated endoscopically and 27 patients were observed without treatment. Endoscopic mucosal resection, endoscopic submucosal dissection, and polypectomy were the methods used for endoscopic treatment. Therapeutic efficacy and rates of complication and recurrence were evaluated retrospectively. RESULTS: In the endoscopic resection group, complete resection was observed in 53 patients (79.1%), and recurrence was observed in 14 patients (20.9%). On analysis of the observation group, no change was observed in 19 patients (70.4%), and tumor progression was observed in 8 patients (29.6%). Median follow-up duration was 49 months (31~210 months). No mortality was reported in either group during follow-up. CONCLUSIONS: Observation of type 1 gastric neuroendocrine tumors without metastasis yields results similar to those produced by endoscopic resection. Observation alone may be a safe treatment.

BACKGROUND: Atropine is an anticholinergic drug which is commonly used in clinical practice. The effect of parasympathetic block with atropine on dynamic cerebrovascular regulation remains unclear. This study was aimed to identify effects of vagolytic atropine on cerebrovascular response during acute orthostatic hypotension in humans. METHODS: Continuous middle cerebral blood flow velocity (CBFV, transcranial Doppler) and arterial blood pressure (ABP, Finometer) were measured during a sit-to-stand procedure in 10 healthy subjects with placebo and vagolytic (10 microg/kg) doses of atropine. Cerebral vascular tone was assessed by cerebrovascular resistance (CVR = ABP / CBFV). Dynamic cerebral autoregulation was also assessed by transfer function analysis of ABP and CBFV. RESULTS: During the standing session, ABP fell to a similar extent in both groups by an average of 23 to 25 mmHg (26% to 29%). CBFV also fell in all subjects but significantly more in vagolytic atropine (-15.0 +/- 7.0 cm/s) compared with placebo (-12.0 +/- 5.8 cm/s, P < 0.05). CVR was decreased significantly in the placebo group during posture change (1.56 +/- 0.44 vs. 1.38 +/- 0.38, P < 0.05), in contrast, lesser decreased in the atropine group (1.60 +/- 0.50 vs. 1.53 +/- 0.42, P = 0.193). Transfer function coherence in the very-low-frequency range was significantly increased in the atropine group during the standing session (0.55 +/- 0.14), compared with the sitting session (0.45 +/- 0.14, P = 0.006). CONCLUSIONS: These data present that vagolytic atropine attenuates cerebral vasodilation response to acute orthostatic hypotension, suggesting the use of atropine may need care in patients with cerebrovascular disease with vagal impairment.

PURPOSE: The purpose was to describe comparative analysis of the surgical outcome of percutaneous K-wire fixation of bony mallet fingers reduced with towel clip and 18-gauge needle. METHODS: We analyzed the bony mallet finger patients with more than twelve months follow-up after percutaneous K-wire fixation. The patients were randomly divided into two groups. Eighteen fingers were treated with closed reduction using towel clip and 18 other fingers were treated with closed reduction using 18-gauge needle. RESULTS: Radiographs showed bony union and no subluxation in all cases after K-wire removal. The average extension lag was 2.8degrees/1.9degrees, and range of motion of distal interphalangeal joint was 70.3degrees/75degrees respectively. According to Crawford's criteria, excellent results were obtained in 9/11 fingers, good results in 8/7 fingers, and poor result in 1/0 finger, respectively. CONCLUSION: 18-gauge needle reduction in percutaneous K-wire fixation is considered less invasive and useful method for treatment of bony mallet finger with comparable results with towel clip reduction.

BACKGROUND: This study was conducted to establish reference intervals (RIs) for serum gamma-glutamyltransferase (GGT), and to evaluate the association between serum GGT levels within RIs and the prevalence of metabolic syndrome (MetS) and type 2 diabetes mellitus (DM) in men and women. METHODS: A total of 363 healthy adults (137 men and 226 women) were enrolled for establishing the RIs of serum GGT. A cross-sectional study was conducted with 919 individuals (519 men and 400 women) to evaluate the associations between gender-specific serum GGT RI quartiles and prevalence of MetS and DM. RESULTS: The RIs for serum GGT levels (central 95th percentile ranges) were 9.0-70.6 IU/L and 4.0-31.3 IU/L in men and women, respectively. In men, the odds ratios (ORs) and 95% confidence intervals (CIs) for the prevalence of MetS in 4 serum GGT quartiles (lowest to highest) were 1.0 (reference), 3.6 (0.7-18.0), 8.8 (2.0-39.1), and 17.4 (4.0-75.3), respectively, while the ORs (95% CIs) for the prevalence of DM were 1.0 (reference), 1.0 (0.3-3.0), 1.7 (0.6-4.6), and 2.6 (1.0-6.6), respectively. In women, the corresponding ORs (95% CIs) were 1.0 (reference), 3.3 (0.6-16.6), 5.8 (1.2-27.3), and 18.8 (4.3-82.2) for MetS, respectively, and 1.0 (reference), 1.6 (0.3-9.7), 1.6 (0.3-9.9), and 8.0 (1.7-36.7) for DM, respectively. These significant relationships persisted after adjusting for age, alcohol intake, body mass index, and smoking. CONCLUSIONS: Serum GGT levels, even within RIs, were proportionally associated with prevalence of metabolic syndrome and DM in both men and women. Serum GGT level may be an independent predictor for chronic degenerative diseases.

We report on two cases of anti-Jka, whose reactivity disappeared on an antibody identification test using enzyme-treated red cells. One of two patients was a 72-year-old female with cirrhosis of the liver and colon cancer, and the other was a 55-year-old female with known MDS and incomplete Behcet's disease. Results of an antibody identification test using a LISS/Coombs gel card (DiaMed AG) showed negative to one positive with red cells having the Jka antigen; however, all reactions using the enzyme-treated cells showed negative results, which was unexpected. The patients' RBC phenotype was Jk(a-b+). We obtained positive results in reactions of enzyme-treated Jka+ cells and EDTA using a patient's serum and proved that the cause of the negative reaction might be complement-related.

Arcanobacterium haemolyticum, a aerobic Gram-positive rod, has been described as an unusual pathogen causing soft tissue infections such as pharyngotonsillitis, chronic ulcer and cellulitis. In addition, the microorganism causes deep-seated infection and systemic disease including endocarditis, vertebral osteomyelitis and sepsis in patients with predisposing conditions such as diabetes mellitus. Since colonies and microscopic findings of A. haemolyticum might be confused with those of streptococci and coryneform bacteria, and it is usually isolated with other microorganisms, it is often considered to be normal flora or a contaminant in wound infections, resulting in missed or delayed diagnosis. Streptococcus agalactiae infections in neonates and pregnant women have been well recognized. However, invasive S. agalactiae infections in non-pregnant older adults with chronic medical conditions, particularly diabetes mellitus, are increasing. We report a case of diabetic foot ulcer due to A. haemolyticum and S. agalactiae in an uncontrolled diabetes mellitus patient.
