Endostatin is released during extracellular matrix remodeling and is involved in the development of vascular pathology and cardiovascular (CV) disease. However, the role of circulating endostatin as a biomarker of vascular calcification and CV events in patients undergoing hemodialysis (HD) remains unclear. Methods: A total of 372 patients undergoing HD were prospectively recruited. Plasma endostatin levels were measured at baseline, and their associations with circulating mineral bone disease (MBD) biomarkers and abdominal aortic vascular calcification scores were analyzed. The primary endpoint was defined as a composite of CV and cardiac events. Results: Plasma levels of patients in endostatin tertile 3 were significantly associated with low-density lipoprotein cholesterol levels and predialysis systolic blood pressure in multivariate analysis. However, endostatin levels did not correlate with circulating MBD biomarkers or vascular calcification scores. Patients in endostatin tertile 3 had a significantly higher cumulative event rate for the composite of CV events (p = 0.006). Endostatin tertile 3 was also associated with an increased cumulative rate of cardiac events (p = 0.04). In multivariate Cox regression analyses, endostatin tertile 3 was associated with a 4.37-fold risk for composite CV events and a 3.88-fold risk for cardiac events after adjusting for multiple variables. Conclusion: Higher circulating endostatin levels were independently associated with atherosclerotic risk factors but did not correlate with MBD markers or vascular calcification. Higher circulating endostatin levels were associated with a greater risk of composite CV events in patients undergoing HD, and endostatin is a biomarker that helps to determine the high risk of CV events.

The voltage-gated Na channel subtype Nav1.7 is important for pain and itch in rodents and humans. We previously showed that a Nav1.7-targeting monoclonal antibody (SVmab) reduces Na currents and pain and itch responses in mice. Here, we investigated whether recombinant SVmab (rSVmab) binds to and blocks Nav1.7 similar to SVmab. ELISA tests revealed that SVmab was capable of binding to Nav1.7-expressing HEK293 cells, mouse DRG neurons, human nerve tissue, and the voltage-sensor domain II of Nav1.7. In contrast, rSVmab showed no or weak binding to Nav1.7 in these tests. Patch-clamp recordings showed that SVmab, but not rSVmab, markedly inhibited Na currents in Nav1.7-expressing HEK293 cells. Notably, electrical field stimulation increased the blocking activity of SVmab and rSVmab in Nav1.7-expressing HEK293 cells. SVmab was more effective than rSVmab in inhibiting paclitaxel-induced mechanical allodynia. SVmab also bound to human DRG neurons and inhibited their Na currents. Finally, potential reasons for the differential efficacy of SVmab and rSVmab and future directions are discussed.

Breast contour deformities, lack of volume and asymmetry are common confronted problems after breast augmentation with implants. These problems can be corrected by using temporary fillers or autologous fat grafts. The purpose of this study was to introduce our experience using long lasting temporary filler (Aquafilling(R)) for the correction of unfavorable results after breast augmentation with silicone implants. Two non-pregnant, non-breastfeeding women unsatisfied with previous breast augmentation with silicone implants were recruited for this study. All procedures were performed under local anesthesia with sedation. Efficacy and safety assessments were carried out at follow-up visits (1, 3, and 6 months). The study showed that Aquafilling(R) could provide satisfactory improvement in breast shape and volume. Also it showed that the corrected volume and shape were lasting without affecting the breasts' original volume. Patients reported high satisfaction as Aquafilling(R) was generally well tolerated with no inflammatory reactions or serious adverse events. We recommend that Aquafilling(R) as a new option for the correction of minor problems after breast augmentation surgery with implants. However, further follow-up studies are required to observe long-term results.

A Middle East respiratory syndrome (MERS) - coronavirus (CoV) cluster that attacked Korea in May 2015 revealed several weaknesses in Korea's health care system in the face of the crisis of an emerging infectious disease and its public health implications. This experience has shown that is necessary to prepare comprehensive countermeasures through the cooperation of civil and public agencies to prevent a second or even third MERS outbreak and to control future crises of infectious disease and public health. The MERS Policy Committee of the Korean Medical Association has thus proposed a master plan for reform of the national infectious disease prevention and management system to prepare a new framework for national infectious disease prevention and control. The specific targets of the master plan are improvement of the system of usage of medical services and of the medical culture among national health insurance subscribers, improvement of the emergency room management system to prevent the spread of infectious disease, the establishment of a support system to promote effective voluntary infectious disease prevention activities among medical institutions, the building of a public health crisis communication system in collaboration with medical organizations, the establishment of an independent Ministry of Health and capacity building of the Korea Centers for Disease Control (KCDC), the securing of an advanced research and development system in the field of prevention and control of infectious disease, and the capacity building of professional epidemiologists and personnel needed to prevent and control infectious disease. The five core strategies of the master plan have been planned by medical experts in this order of priority: the reform of the healthcare delivery system, the independence of the Ministry of Health and capacity building of the KCDC, fundraising for a public infection management fund, enforcement of medical organization infection control, and improvement of the emergency room management system.

The inflammation of colonic diverticulum, diverticulitis, is occasionally accompanied by several complications, such as bleeding, bowel obstruction, fistula and abscess formation. Both colo-ovarian fistula and tuboovarian abscess formation, as complications of diverticulitis, are rare. Here, we report a case of colonic diverticulitis which ultimately resulted in colo-ovarian fistula and tuboovarian abscess formation. A 76-year-old female was presented with lower abdominal pain, diarrhea and intermittent hematochezia for about 1 month. According to the abdominal computed tomography, tuboovarian abscess was shown to adhere to the inflamed sigmoid diverticulum. Sigmoidoscopy revealed pus flowing from the opening of the diverticulum at the sigmoid colon. Hence, the patient underwent oophorosalpingectomy and low anterior resection. Thereafter, she was treated with bowel rest and broad spectrum antibiotics, and finally recovered. Although rare, colonic diverticulitis may result in colo-ovarian fistula causing tuboovarian abscess formation in postmenopausal patients. Early recognition of the condition and appropriate treatment, including surgery and antibiotics, are necessary in order to achieve full recovery from complicated diverticulitis.

There are many reports about causes of corrosive agents such as acids and alkaline and occasionally hot food in either liquid or solid forms as causes of upper gastrointestinal mucosal injury. However, there have been no reports on bowel preparation solutions as a cause of upper gastrointestinal injury. We describe a case of bowel preparation solution (PICOLIGHT powder) induced thermal injury of the gastric mucosa with a review of the literature.

Here, we report a case of newly diagnosed diabetes, with concurrent pancreatic cancer manifested as hyperglycemic crisis, and aggravated by urinary tract infection. We summarize the initial clinical manifestations and pertinent laboratory, radiologic, and clinical findings in an elderly patient with hyperglycemic emergency. A review of the documents involving pancreatic tumors and hyperglycemic hyperosmolar state, which is an acute complication of diabetes mellitus, is presented. In the absence of other identifiable conditions, it is reasonable to speculate that some factor (or factors) produced by the tumor had a role in the metabolic decompensation. In addition, this discussion should be more carefully considered in the aged people group.

BACKGROUND AND OBJECTIVES: Obliterative otitis media is a condition in which the entire middle ear cavity is filled up with fibrous tissue and with intact tympanic membrane. The aim of this study was to define the clinical features and analyze the treatment outcomes of this disease. SUBJECTS AND METHOD: Between January 2000 and August 2011, 16 patients consistent with the criteria of obliterative otitis media were analyzed retrospectively. RESULTS: All patients had intact but thickened eardrum, with mixed hearing loss of mild to moderate degree. The video pneumatic otoscopic examination revealed very limited mobility of eardrum. Myringotomy did not reveal any air-filled spaces or fluid in the tympanic cavity. There was no significant improvement of hearing after myringotomy or ventilation tube insertion. CONCLUSION: Obliterative otitis media is a discrete clinical entity and should not be confused with otitis media with effusion or adhesive otitis media.

A phytobezoar is the most common type of bezoar, which is a gastrointestinal mass composed of vegetable. A persimmon is a common cause of a phytobezoar. The majority of bezoars are found in the stomach, with the small intestine being the next most commonly involved site. The colon is a rare site for a bezoar. Recently, we experienced a colonic bezoar that caused colonic obstruction in a 66-year-old female patient who took persimmons regularly. The patient came to the hospital because of abdominal pain and distension. To differentiate a tumor or other problems that can cause intestinal obstruction, we performed an abdominal computed tomography scan and found an ovoid intraluminal mass with a mottled gas pattern in the distal descending colon. A large impacted bezoar was seen in the sigmoid colon, which was completely obstructed, and it was successfully removed by using colonoscopy.

A 59-year-old man treated with pneumococcal meningitis 4 months ago was hospitalized for acute heart failure and performed aortic valve replacement by rupture of aortic valve. The frequent association of pneumococcal meningitis and endocarditis is known as Austrian syndrome. Though Austrian syndrome is a clinically rare disease, the evolution of pneumococcal endocarditis is very aggressive and associated with high mortality, and early recognition for evidence of endocardial lesion in patients with pneumococcal meningitis is important to reduce the complications and mortality rate.
