Background:
Readmissions related to lack of quality care harm both patients and health insurance finances. If the factors affecting readmission are identified, the readmission can be managed by controlling those factors. This paper aims to identify factors that affect readmissions of convalescent rehabilitation patients.
Methods:
Health Insurance Review and Assessment Service claims data were used to identify readmissions of convalescent patients who were admitted in hospitals and long-term care hospitals nationwide in 2018. Based on prior research, the socio-demographics, clinical, medical institution, and staffing levels characteristics were included in the research model as independent variables. Readmissions for convalescent rehabilitation treatment within 30 days after discharge were analyzed using logistic regression and generalization estimation equation.
Results:
The average readmission rate of the study subjects was 24.4%, and the risk of readmission decreases as age, length of stay, and the number of patients per physical therapist increase. In the patient group, the risk of readmission is lower in the spinal cord injury group and the musculoskeletal system group than in the brain injury group. The risk of readmission increases as the severity of patients and the number of patients per rehabilitation medicine specialist increases. Besides, the readmission risk is higher in men than women and long-term care hospitals than hospitals.
Conclusion
“Reducing the readmission rate” is consistent with the ultimate goal of the convalescent rehabilitation system. Thus, it is necessary to prepare a mechanism for policy management of readmission.

Background/Aims:
The objective of this study was to determine the more appropriate wound-closure method by comparing the effectiveness of two methods in a group of patients who underwent ileostomy repair.
Methods:
The study conducted after obtaining the approval of the Institutional Review Board (IRB) included 58 patients ≥19 years of age who underwent ileostomy at the Department of Surgery at the Presbyterian Medical Center. This was a retrospective, single-center trial. Patients who underwent ileostomy closure between January 2011 and September 2017 were assigned to the primary wound-closure (PC, n=25) group and the purse-string wound-closure (PSC, n=33) group. Post-repair complications, such as wound infection, delayed healing, and patient satisfaction related to wound management, were investigated and compared according to the wound-closure method.
Results:
The PSC group had a significantly lower surgical site infection rate than the PC group (0% vs. 44%, p<0.001). The wound-healing period was also significantly different between the PC and PSC groups (mean 27.18 days vs. 20.96 days, p=0.023). However, the postoperative wound-healing delay of >30 days was not significantly different (39% vs. 20%, p=0.114). In addition, there were no significant differences in the response to questionnaires on patient satisfaction between the two groups.
Conclusions
PSC has a lower surgical site infection rate and the wound-healing delay was not very different from that of PC. Therefore, if patients are at risk of wound infection, such as in severe wound contamination, long operating time, and immunocompromised conditions, we should consider PSC as a wound closure method of choice.

Kommerell diverticulum is a rare congenital anomaly of the aortic arch characterized by dilation at the proximal descending aorta, which gives rise to an aberrant subclavian artery. Kommerell diverticulum is usually asymptomatic, but can also be associated with symptoms due to compression of the esophagus or trachea, and can rarely be fatal due to dissection or rupture of the diverticulum. Here, we report a rare case of dysphagia caused by compression of the esophagus by Kommerell diverticulum originating from the right-sided aortic arch.

BACKGROUND: Perfusion scintigraphy with dipyridamole have been reported to be useful for diagnosis of coronary artery disease and the assessment of the presence and extent of myocardium at ischemic risk, especially in patients who can not undergo dynamic exercise testing. Dipyridamole, pharmacologic coronary vasodilator, also induces fall in blood pressure and rise in heart rate. The purpose of this study was to answer the question if dipyridamole induced peripheral hemodynamic responses were related to chest pain, ST changes on EKG, scintigraphic defect or extent of coronary stenosis. METHODS: Dipyridamole 99mTc-MIBI myocardial scintigraphy and coronary angiography on 43 subjects who were suspected to have coronary artery disease. The peripheral hemodynamic response was graded as absent(group 0) if there was a < or =10mm fall in systolic blood pressure (SBP) and/or < or =10 beats/min rise in geart rate(HR) ; moderate(group 1) if there was >10 but < or =20mm fall in SBP and/or >10 but < or =20 beats/min rise in HR ; and marked (group 2) if there was >20mm fall in SBP and/or >20 beats/min rise in HR. RESULTS: The overall diagnostic sensitivity and specificity for coronary artery disease of dipyridamole perfusion scintigraphy were 68%, 83% while per vessel sensitivity and specificity for coronary artery disease were 66%, 97%. The numbers of induced chest pain and ischemic ST changes among hemodynamic subgroups, were 40%, 40% in group 0, 33%, 27% in group 1 and 50%, 40% in group 2 without significant difference in each hemodynamic subgroups. Either the numbers of diseased coronary arteries or the numbers of patients demonstrationg reversible scintigraphic defects were not statically different among each subgroups. CONCLUSION: Although the peripheral hemodynamic response dose not always correlate with its central coronary effect but dipyridamlole 99mTc-MIBI myocardial perfusion scintigraphy is an useful test for diagnosis of coronary artery disease.

OBJECTIVE: To find simple screening method for assessment of patients with diabetic neuropathy by use of brief questionnaire, scored physical examination including vibration perception threshold, and mixed median conduction study. METHOD: Subjects were 24 patients with diabetes mellitus. Conventional nerve conduction study was performed in 24 patients and the patients were divided into two groups: 11 patients with polyneuropathy; 13 patients of normal findings. The questionnaires were given for evaluation of sensory function in all the subjects. The questionnaires were followed by physical examination including two point discrimination, vibration perception threshold by using biothesiometer, 10 gram filament test, pin prick test, DTR check, and muscle strength test. Abnormality was determined by the number of positive responses or abnormal clinical findings. Finally, we recorded the conduction velocity and amplitude of median mixed nerve and compared these parameters to values of 20 normal adults. RESULTS: The questionnaire and physical exam scores were higher in patients with polyneuropathy (p<0.01). The patients with polyneuropathy showed higher vibration perception threshold values (p<0.01) and slower conduction velocity and smaller amplitude of median mixed nerve (p<0.05). In correlation with conventional nerve conduction study, the median mixed nerve conduction velocity had higher kappa value than amplitude in screening for diabetic polyneuropathy. CONCLUSION: We suggest the questionnaires, scored physical examination, vibration perception threshold, and median mixed nerve conduction velocity to be a simple screening method for assessment of patients with diabetic plyneuropathy.

Collapsing glomerulopathy (CG) has become an important cause of end-stage renal disease (ESRD). First delineated from other proteinuric glomerular lesions in the 1980s, CG is now recognized as a common, distinct pattern of proliferative parenchymal injury that portends a rapid loss of renal function and poor responses to empirical therapy. The first cases in the literature trace back to human-immunodeficiency-virus (HIV)-negative patients who underwent biopsy in 1979. A 45-year-old male patient complained of hematuria and proteinuria eight years ago. He showed an abrupt serum creatinine increase from 1.75 to 2.65mg/dL in the last preceding months. Afterwards, his serum creatinine progressively increased up to 6.82mg/dL. Moreover, his 24 h urine protein level was determined to have reached 6,171 mg/day, as opposed to 670 mg/day a year earlier. Consequently, renal biopsy was performed, and its result showed collapsing glomerulopathy, compatible with the diagnosis. He has undergone continuous ambulatory peritoneal dialysis as renal replacement therapy. Thus, it is reported herein that a patient clinically diagnosed with chronic kidney disease eight years ago showed a sudden renal-function decrease and was clinicopathologically diagnosed with collapsing glomerulopathy based on the results of his renal biopsy.

BACKGROUND/AIMS: The aims of our study are to assess the frequency of peripheral blood mononuclear cell (PBMC) proliferation and cytokine profiles to hepatitis C virus (HCV) core protein and NS3 protein to search the potential immunosuppressive effect of HCV core in chronically HCV-infected patients. Subjects and METHODS: Thirty two anti-HCV-positive patients with chronic liver diseases, eight HBsAg-positive patients with chronic liver diseases, and six healthy adults were the subjects of our study. Using recombinant HCV core and NS3, proliferative response of PBMC and cytokine production were determined. RESULTS: Fifty nine percent and thirteen percent of patients with HCV-related chronic liver diseases showed positive PBMC proliferation to HCV core and NS3, respectively. Thirty four percent and fifty nine percent of patients with HCV-related chronic liver diseases showed significant production of interferon-gamma to HCV core and NS3, respectively. IL-4 production was negligible. When the PBMC were treated with HCV core and NS3 concurrently, or HCV core and phytohemagglutinin concurrently, the stimulation indices were significantly decreased compared to those treated either with NS3 or PHA without core. CONCLUSIONS: Although about two thirds of chronically HCV-infected patients with liver diseases showed the PBMC proliferation and Th 1 type cytokine profile, they could not eradicate the viral infection. This ineffective immune response seems to play a role in the pathogenesis of chronic inflammatory liver disease resulting in liver cirrhosis and hepatocellular carcinoma. HCV core showed a potential immunosuppressive effect, which has important meaning for the mechanism of HCV persistence.

The clinical course and management of aneurysm by intracranial arterial dissection are not well known. Since intracranial dissecting aneurysm has a higher bleeding risk than an extracranial one, the optimal choice of treatment is controversial. We report two patients who presented with a dissecting aneurysm in the intracranial vertebral artery without subarachnoid hemorrhage. They showed successful responses to antiplatelet treatment without any surgical interventions.

Posterior reversible encephalopathy syndrome (PRES) is a rare clinico-radiological syndrome that is characterized by an acute onset of headache, vomiting, visual abnormalities, confusion, and/or seizures and is typically accompanied with edema of predominantly posterior portions of the cerebral hemispheres. Here, we report a case of PRES with cerebral hemorrhage that occurred in a female pediatric patient with uncontrolled nephrotic syndrome. The patient's magnetic resonance imaging (MRI) studies showed asymmetric white matter abnormalities, cerebral hemorrhage, and restricted diffusion. After controlling her hypertension and nephrotic syndrome, her neurologic symptoms improved, and follow-up MRI findings revealed interval resolving of the white matter lesions.

PURPOSE: Papillary thyroid cancer with level VII (anterior superior mediastinal lymph nodes) lymph node metastasis belongs to Stage IV a according to the Americal Joint Committee on Cancer cancer staging. The aim of our study was to identify clinicopathologic factors that are related to level VII cervical lymph node metastasis and to suggest recommendations for level VII dissection. METHODS: We reviewed 195 patients with papillary thyroid carcinoma who had their initial operation containing level VII dissection from April 2006 to June 2007. Level VII dissection involved lymph nodes in the anterior superior mediastinum and tracheoesophageal grooves, extending from the suprasternal notch to the innominate artery. Clinicophathologic factors, such as gender, age and lateral neck metastasis, related to Level VII metastasis were analyzed by tumor size, multifocality of tumor, extrathyroidal extension and lymphovascular invasion. RESULTS: Nine (4.6%) of 195 patients with papillary thyroid carcinoma had level VII metastasis. Clinicopathologic factors that were related to level VII metastasis included lateral neck metastasis (P < 0.01), tumor size (P < 0.01) and lymphovascular invasion (P < 0.05). CONCLUSION: If preoperatively, the tumor size is over 1.5 cm, or there is lateral neck metastasis, level VII dissection must be considered. If there is lymphovascular invasion pathologic findings postoperatively, special attention should be paid for detection of level VII recurrence.
