Autosomal dominant polycystic kidney disease (ADPKD), one of the most common human monogenic diseases, is characterized by the presence of numerous fluid-filled renal cysts and is a leading cause of end-stage renal disease (ESRD). Urinary biomarkers may be useful for predicting the variable course of ADPKD progression from cyst growth to ESRD. Methods: To identify candidate urinary biomarkers of ADPKD progression, we used CRISPR/Cas9 genome editing to generate porcine fibroblasts with mono- and biallelic ADPKD gene knockout (PKD2+/– and PKD2–/–, respectively). We then performed RNA-sequencing analysis on these cells. Results: Levels of osteopontin (OPN), which is expressed by renal epithelial tubular cells and excreted into urine, were reduced in PKD2–/– cells but not in PKD2+/– cells. OPN levels were also reduced in the renal cyst cells of ADPKD patients. Next, we investigated whether OPN excretion was decreased in patients with ADPKD via enzyme-linked immunosorbent assay. OPN levels excreted into renal cyst cell culture media and urine from ADPKD patients were decreased. To investigate whether OPN can predict the rate of ADPKD progression, we compared urinary excretion of OPN in ADPKD patients with slow progression and those with rapid progression. Those with rapid progression had an estimated glomerular filtration rate of >60 mL/min/1.73 m2 . Urinary OPN excretion levels were lower in rapid progressors than in slow progressors. Conclusion: These findings suggest that OPN is a useful urinary biomarker for predicting ADPKD progression.

A 44-year-old woman presented with right upper abdominal pain and nausea with a 4-day duration. An abdominopelvic CT scan revealed a 2.3-cm sized cystic lesion in the duodenum with inflammatory changes and partial thrombosis in the distal main portal vein. Empirical antibiotics were initiated considering acute duodenal diverticulitis, but the symptoms worsened. Side-viewing duodenoscopy revealed purulent fluid draining spontaneously from a small diverticular opening. After enlarging the opening using an extraction balloon, sweeping followed by saline irrigation was performed, and pus and food debris gushed out into the duodenal lumen. The patient recovered rapidly and was discharged uneventfully on the 5th day post-hospitalization with oral antibiotics and warfarin. A follow-up CT scan and duodenoscopy 1 month later revealed a normal-appearing duodenal diverticulum and complete resolution of the portal vein thrombosis. This paper reports a rare case of portal vein thrombosis associated with duodenal diverticulitis. Overall, endoscopic therapy can be effective when conservative management fails and might be a viable alternative to surgery for treating duodenal diverticulitis.

Diabetic ketoacidosis (DKA) is an acute complication related to severe hyperglycemia. While the mortality rate for DKA is low with appropriate therapy, several complications may lead to deterioration of the clinical course. Here, we report a case of a 23-year-old patient with DKA who suffered from a rare but hemodynamically unstable cardiac arrhythmia, polymorphic ventricular tachycardia with prolonged QT interval, or Torsades de Pointes. During the recovery phase of DKA, three episodes of Torsades de Pointes suddenly occurred, and were recovered by immediate defibrillation. The patient did not have structural heart disease or a genetic predisposition. To the best of our knowledge, this is the first report of an adult with DKA complicated with QT prolongation related to Torsades de Points after correction of ketosis. To manage DKA, more attention may be needed on changes in the QT interval as well as risk factors for Torsades de Points.

OBJECTIVE: To investigate trends of the research designs and statistical methods in the Annals of Rehabilitation Medicine (ARM) published from 2005 to 2015 through a comparison of articles with the Archives of Physical Medicine and Rehabilitation (APMR). METHODS: The authors reviewed all articles published in ARM and APMR for the years 2005 and 2015 in order to determine their research designs as well as their statistical methods used in each article. RESULTS: In ARM, randomized controlled trials increased from 4.5% in 2005 to 6.5% in 2015. In APMR, randomized controlled trials increased from 8.1% in 2005 to 14.0% in 2015, meta-analyses increased to 5.3%, and systematic reviews increased to 6%. The number of studies using statistical methods increased in ARM from 1.9 to 2.6 per article and in APMR, from 2.7 to 3.1. Use of advanced methods in ARM also showed an increase from 2005 to 2015. CONCLUSION: This study concludes that there is a trend of increased awareness and attempts to use varied research approaches in ARM articles. There should also be more in-depth discussions and opportunities for researchers to share their experiences regarding statistical methods in the clinical field.

Mechanisms and causes of cerebral infarction, usually two mechanisms, are identified: hemodynamics and thrombotic or thromboembolic causes. Compressive causes by tumor are not reported in the main etiological classifications as Trial of Org10172 in Acute Stroke Treatment (TOAST) classification and ASCO (atherosclerosis, small vessel disease, cardiac source, and other causes). However tumors found in these locations often involve an intracranial portion of the internal carotid artery (ICA) and may compromise cerebral blood flow. Cerebral infarction related to meningioma, the common extra-axial brain tumor in adults, has been rarely reported. We experienced an extremely rare case of cerebellar infarction resulting from direct compression of the vertebral artery by cervical meningioma. To the best of our knowledge, there are no documented cases of a meningioma causing stroke by vertebral artery occlusion. We report on a case of meningioma presenting with cerebellar infarction as a result of vertebral artery compression.

The objective of this study was to examine job performance and importance, and job satisfaction of school foodservice dietitians, nutrition teacher in Jeonnam and Gwangju area according to the school types (elementary school, middle school, high school). A total of 646 questionnaires were distributed, 244 questionnaires were analyzed using SPSS 12.0 for a descriptive analysis, t-test and ANOVA. There were significant differences between the school dietitians', nutrition teachers' job performance and importance in all areas of the job analysis for all school types. In the foodservice management/evaluation and nutrition education area, elementary and middle school foodservice dietitians, nutrition teacher showed a significantly higher performance, compared to that of high school dietitians, nutrition teacher. Nutrition education was recognized by elementary and middle school dietitians, nutrition teacher to be more significantly important than that of high school dietitian, nutrition teacher. Elementary school foodservice dietitians, nutrition teacher was most satisfied with their job condition. Dietitian working in middle school was least satisfied with the salary and compensation. These results suggest that appropriate curriculum should be structured according to foodservice dietitians, nutrition teacher of the school type for improving the work efficiency. In order to increase the job satisfaction, the employment status of school dietitian should be guaranteed by the government and school officials, especially in the middle and high schools.

Renal artery aneurysm (RAA) is a rare disease, and the precise incidence has not been very well known. It appears that with the increasing use of diagnostic ultrasound, computed tomography and arteriography, RAA are being identified more frequently than in the past. Rupture of RAA is associated with 10% mortality and the chance of nephrectomy is very high. Although, most of renal artery aneurysms are treated by endovascular technique, surgery is often necessary for aneurysms associated with bifurcation area or large braches. Here, we report a case of saccular renal artery aneurysm which was managed by open surgery.
