Spinal cord injury (SCI) is one of the most devastating conditions and many SCI patients suffer neurological sequelae. Stem cell therapies are expected to be beneficial for many patients with central nervous system injuries, including SCI. Adult stem cells (ASCs) are not associated with the risks which embryonic stem cells have such as malignant transformation, or ethical problems, and can be obtained relatively easily. Consequently, many researchers are currently studying the effects of ASCs in clinical trials. The environment of transplanted cells applied in the injured spinal cord differs between the phases of SCI; therefore, many researchers have investigated these phases to determine the optimal time window for stem cell therapy in animals. In addition, the results of clinical trials should be evaluated according to the phase in which stem cells are transplanted. In general, the subacute phase is considered to be optimal for stem cell transplantation. Among various candidates of transplantable ASCs, mesenchymal stem cells (MSCs) are most widely studied due to their clinical safety. MSCs are also less immunogenic than neural stem/progenitor cells and consequently immunosuppressants are rarely required. Attempts have been made to enhance the effects of stem cells using scaffolds, trophic factors, cytokines, and other drugs in animal and/or human clinical studies. Over the past decade, several clinical trials have suggested that transplantation of MSCs into the injured spinal cord elicits therapeutic effects on SCI and is safe; however, the clinical effects are limited at present. Therefore, new therapeutic agents, such as genetically enhanced stem cells which effectively secrete neurotrophic factors or cytokines, must be developed based on the safety of pure MSCs.

Extradural spinal meningiomas are uncommon, and their pathophysiology is not entirely understood. Here, we present the case of a 49-year-old woman with low back and left leg pain of 5 years duration. Magnetic resonance imaging revealed a mass, 1.8-cm in size, with rim enhancement in the spinal canal at the T12 level and extending into the left T12-L1 foramen. In the surgical field, the mass presented with the characteristics of an extra-intradural spinal meningioma. The patient underwent a T12 total laminectomy. A linear durotomy was performed at the midline, and the intradural portion was removed. The extradural portion was not separable from the adjacent dura and the left T12 root, and it was removed by dural excision. Pathological examination confirmed the diagnosis of psammomatous meningioma. We also conducted a literature review of similar cases. Based on our experience with this case, we believe that it is important to clearly distinguish extradural meningiomas from other types of tumors as misdiagnosis can change the operative plan. The long term prognosis of extradural meningiomas is not clear but total excision is thought to be essential.

PURPOSE: To compare extended care facility (ECF) and home as discharge destination after total knee arthroplasty (TKA) at a single high-volume tertiary center in South Korea. MATERIALS AND METHODS: We retrospectively analyzed 1,120 primary TKAs (614 patients) performed between January 2012 and December 2013. A telephonic survey was conducted to determine discharge destination. The data reviewed included demographic and surgical data, functional outcome at 2 years and complications within 3 months. RESULTS: ECF and home received 316 patients (51%) and 298 patients (49%), respectively. The ECF group had more bilateral TKA patients than the home group (272 vs. 234; p=0.014) and more patients with additional hospital stay (44 vs. 22; p=0.009). A higher tendency of complications was seen at home (n=8, 2.7%) than the ECF (n=2, 0.6%) (p=0.057). No significant differences were found in any functional outcome measure. Home patients had better patient satisfaction than ECF patients (81.9% vs. 54.3%; p < 0.001). CONCLUSIONS: Patients who returned home after discharge had similar functional outcome at 2 years after surgery and higher patient satisfaction than those in the ECF in spite of the higher tendency of complications. Patients need adequate counseling and education regarding advantages and limitations of the two discharge destinations.

This is a case report of complete mouth rehabilitation in a patient with generalized attrition and loss of posterior support. After analyzing the condition of the temporomandibular joint, multiple implants were placed to restore collapsed occlusion. Fixture/abutment level intraoral scanning was done instead of using conventional impression materials which entail multiple bite registration for cross-mounting. A ‘jaw motion tracking’device, ‘digital face-bow transfer’, and ‘double scan technique’ which enables duplicating temporary restoration to definitive restoration were used to fabricate definitive prostheses. By using various digital techniques, complete mouth rehabilitation was done with minimal chair time in a patient with unstable occlusion.

The anti-inflammatory effects of an ethanol extract of Angelica gigas (EAG) were investigated in vitro and in vivo using croton oil-induced inflammation models. Croton oil (20 microgram/mL) up-regulated mRNA expression of cyclooxygenase (COX)-I and COX-II in the macrophage cell line, RAW 264.7, resulting in the release of high concentrations of prostaglandin E2 (PGE2). EAG (1~10 microgram/mL) markedly suppressed croton oil-induced COX-II mRNA expression and PGE2 production. Application of croton oil (5% in acetone) to mouse ears caused severe local erythema, edema and vascular leakage, which were significantly attenuated by oral pre-treatment with EAG (50~500 mg/kg). Croton oil dramatically increased blood levels of interleukin (IL)-6 and PGE2 without affecting tumor-necrosis factor (TNF)-alpha and nitric oxide (NO) levels. EAG pre-treatment remarkably lowered IL-6 and PGE2, but did not alter TNF-alpha or NO concentrations. These results indicate that EAG attenuates inflammatory responses in part by blocking the COX-PGE2 pathway. Therefore, EAG could be a promising candidate for the treatment of inflammatory diseases.

BACKGROUND: The objective of the present study was to evaluate whether left ventricular diastolic function is altered in rheumatoid arthritis. METHODS: Thirty-six patients of rheumatoid arthritis diagnosed by 1988 revised criteria for rheumatoid arthritis and 20 cases of normal control group were matched with respect to left ventricular ejection fraction and diastolic parameters. RESULTS: Parameters of diastolic function such as peak filling rate, time to peak fillling rate and 1/3 filling rate were not significantly different between patients with rheumatoid arthritis and control groups. although time to peak filling rate was significantly prolonged in seropositive group(p<0.05). CONCLUSION: Left ventricular diastolic function is notes not to be impaired in patients with rheumatoid arthritis.

BACKGROUND: Atherosclerosis, a major problem in patients undergoing chronic dialysis treatment, has been characterized as an inflammatory disease. Cardiovascular disease is the major cause of mortality, accouting for approximately half of all deaths in this population. The present study was aimed whether CRP, an important inflammatory marker, might be associated with cardiovascular risk in dialysis patients. METHODS: We performed retrospective study in 77 dialysis patients. Patients were divided into the elevated CRP group (>8 mg/L, n=11) and the normal CRP group (8 mg/L) showed significant higher cardiovascular events (by chi-squre test, p=0.032). BMI, smoking, alcohol, dialysis modality, lipid parameters, BUN, serum creatinine, serum protein, serum albumin and seurm TIBC did not show significant difference between two groups. Correlation between CRP and other biochemical parameters was analysed. Only ESR was positively correlated with CRP. In a subsequent analysis, elevated CRP group had significantly higher cardiovascular risk (by stepwise logistic regression method, odd ratio = 6.59;95% CI, 1.13 to 38.28). CONCLUSION: These results suggest that CRP level is correlated with cardiovascular risk in dialysis patients.

A giant colonic diverticulum is a rare complication of diverticulosis, and an inguinal hernia is a common diagnosis for patients presenting with a painful groin mass. A 52-year-old male presented to the emergency room with a 3-hour complaint of progressive, constant, right-groin pain with an inguinal mass. After manual reduction of the inguinal hernia, the patient complained of pain in the right upper quadrant. Operative findings showed a transverse colon diverticulitis without perforation. We report here that case of a transverse colon giant diverticulum presenting as an atypical incarcerated inguinal hernia.

Persistent cloaca is a very rare congenital malformation with the incidence of 1/50,000-250,000 births. This malformations have a single common perineal opening for the genital, urinary and gastrointestinal tracts. Because of wide spectrum of abnormal anatomy involving upper urinary tract, gastrointestinal systems, cardiovascular system, central nervous system, and respiratory system, prenatal diagnosis is difficult through ultrasound during pregnancy. It has been reported that if the anomalies are diagnosed early, they can be corrected surgically. We present a case of persistent cloaca with meconium peritonitis and hydrometrocolpos confirmed by neonatal surgery after emergency cesarean section.
