BACKGROUND/AIMS: There is limited data to compare the clinical characteristics and recurrence rates between left-sided primary epiploic appendagitis (PEA) versus left-sided acute colonic diverticulitis (ACD), and right-sided PEA versus right-sided ACD, respectively.METHODS: We retrospectively reviewed the medical records and radiologic images of the patients who presented with left-sided or right-sided acute abdominal pain and had computer tomography performed at the time of presentation showing radiological signs of PEA or ACD between January 2004 and December 2014. We compared the clinical characteristics of left PEA versus left ACD and right PEA versus right ACD, respectively.RESULTS: Fifty-six patients (left:right = 27:29) and 308 patients (left:right = 24:284) were diagnosed with symptomatic PEA and ACD, respectively. Left-sided PEA were statistically significantly younger (50.2 ± 15.4 years vs. 62.1 ± 15.8 years, P= 0.009), more obese (body mass index [BMI]: 26.3 ± 2.9 kg/m² vs. 22.3 ± 3.1 kg/m² , P< 0.001), and had more tendencies with normal or mildly elevated high-sensitivity C-reactive protein (hsCRP) (1.2 ± 1.3 mg/dL vs. 8.4 ± 7.9 mg/dL, P< 0.001) than patients with left-sided ACD. The discriminative function of age, BMI and CRP between left-sided PEA versus left-sided ACD was 0.71 (cutoff: age ≤ 59 years, sensitivity of 66.7%, specificity of 77.8%), 0.84 (cutoff: BMI > 24.5 kg/m² , sensitivity of 80.0%, specificity of 80.0%) and 0.80 (cutoff: CRP < 1.8 mg/dL, sensitivity of 72.2%, specificity of 85.7%).CONCLUSIONS: If patients with left lower quadrant abdominal pain are less than 60 years, obese (BMI > 24.5 kg/m² ) with or without normal to mild elevated CRP levels (CRP < 1.8 mg/dL), it might be necessary for clinicians to suspect the diagnosis of PEA rather than ACD.

OBJECTIVE: Patterns of clinical use of antipsychotics have changed greatly in the past decade. The authors' goal was to examine these patterns in an inpatient unit at a university hospital between 1997, 2003-2004, and 2009-2010. METHODS: We evaluated medication use in inpatients treated with antipsychotic drugs during 2009-2010 (n=379) and compared the results with inpatients treated with antipsychotics in 2003-2004 (n=379) and inpatients treated with antipsychotics in 1997 (n=165). RESULTS: The distribution of psychiatric diagnoses in 2009-2010 was different from that in 2003-2004 and 1997. The proportion of patients with schizophrenia spectrum disorders was higher in 2009-2010 (p=0.013, p<0.001). An atypical agent was prescribed for 98.7% (n=374) of patients in 2009-2010. This represents a significant proportional increase over both 2003-2004 (93.7%, n=355; p<0.001) and 1997 (57.6%, n=95; p<0.001). In 2009-2010 the number of patients receiving prescriptions of two or more antipsychotics in combination was 16.1% (n=61), which represents a significant proportional increase over 2003-2004 (9.0%, n=34; p=0.007) and 1997 (4.8%, n=8; p=0.001). CONCLUSION: The present study demonstrates that atypical antipsychotic medications have replaced typical antipsychotic medications. Polypharmacy increased markedly despite limited empirical evidence of cost-risk-benefit relationships.

Idiopathic chronic ulcerative enteritis (ICUE) is a rare disease with a mortality rate exceeding 75%, which manifests as an ulceration of the small bowel in the absence of a recognizable cause. It is diagnosed by biopsy. A 31-year-old man who had a 10-year history of recurrent episodes of abdominal pain was admitted with a 10-day occurrence of abdominal pain and fever. Upper endoscopy showed multiple active ulcers from duodenal second to distal portion. Colonoscopy revealed diffuse ulcerations at the terminal ileum. Colonic findings were normal. The patient was treated with intravenous antibiotics, systemic steroids, and total parenteral nutrition in the intensive care unit. Ten days after admission, the patient fell into shock due to massive hematochezia and underwent an emergency surgical resection, which revealed Meckel's diverticulum. Bleeding was uncontrolled and the following day surgical resection and intraoperative endoscopy of the highly involved jejunum revealed severe ulcerative bleeding. Microscopic examination revealed ulcerations with pseudopolyps and granulation tissue and no evidence of vasculitis, suggestive of ICUE.

OBJECTIVE: The Purpose of the study was to investigate the bone morphogenic protein expression of rhBMP-2(recombinant human bone morphogenic protein-2) as singnaling molecule and beta-TCP(Tricalcium phosphate) as a bone substitute and carrier medium of rhBMP-2. MATERIALS AND METHODS: 16 rabbits divided into 2 group of each 8 rabbit. Two standardized bone defect, round bilateral defect was made in the cranium of the 8 rabbit of first group, and was grafted with 150~500micrometer diameter beta-TCP 0.25g in one side, which was soaked with rhBMP-2, and autogenous bone was grafted on another side as a positive control. Second group of 8 rabbit, only beta-TCP was grafted with same size and same manner. After 2, 4, 8, and 12 weeks, specimen was taken for microscopic immunohiostochemical and histomorphometric analysis. RESULT: Grafting beta-TCP with rhBMP show the early formation of the bone regenerative factor (BMP-4) and more quantity of new bone formation than only use of beta-TCP (8,12 week), even show less new bone formation than autogenous bone. CONCLUSION: The experimental study result that beta-TCP graft combination with rhBMP-2 as a delivery system is an effective with osteoinductive capacity and biodegradable properties, so that provide clinical availibility of composite use in reconstruction of bony defect.

The present study aimed to investigate the osteogenic potentials of differentiated osteoblast-like cells (DOCs) induced from bone marrow-derived mesenchymal stem cells (MSCs) on beta-tricalcium phosphate (beta-TCP) with recombinant human bone morphogenetic protein (rhBMP-2) in vitro. Osteoblast differentiation was induced in confluent cultures by adding 100 nM dexamethasone, 10 mM beta-glycerophosphate, 50 mM L-ascorbic acid. The Alizarin red S staining and reverse transcriptase-polymerase chain reaction (RT-PCR) were perfomed to examine the mRNA expression of alkaline phosphatase (ALP), bone sialoprotein (BSP), osteocalcin (OCN), receptor activator for nuclear factor kappaB ligand (RANKL), runt-related transcription factor 2 (RUNX2), collagen-I (COL-I). There were no significant differences in the osteogenic potentials of DOCs induced from MSCs on beta-TCP(+/-). According to the incubation period, there were significant increasing of Alizadin red S staining in the induction 3 weeks. The mRNA expression of ALP, RUNX2, and RANKL were higher in DOCs/beta-TCP(-) than DOCs/beta-TCP(+). According to rhBMP-2 concentrations, the mRNA expression of BSP was significantly increased in DOCs/beta-TCP(+) compared to that of DOCs/beta-TCP(-) on rhBMP 10 ng/ml. Our study presented the beta-TCP will have the possibility that calcium phosphate directly affect the osteoblastic differentiation of the bone marrowderived MSCs.

PURPOSE: Cyclosporine A (CsA) is a versatile immunosuppresive agent used to prevent graft rejection syndrome and treat autoimmune disease. One of the major side effects associated with CsA is the abnormal gingival hyperplasia. The purpose of this study was to investigate the relationship between the mRNA expression of the MMP-1, TIMP-1, and TGF-beta1 and the concentration of CsA in cultured human gingival keratinocytes. MATERIALS AND METHODS: Gingival keratocytes were obtained from gingival tissues of 4 healthy donors. The cultured gingival keratocytes were incubated with increasing concentrations of CsA (0-2000 ng/ml) for 24 hours and the expression of MMP-1, TIMP-1, and TGF-beta1 were determined by reverse transcription-polymerase chain reaction (RT-PCR). RESULTS: The expressions of MMP-1 and TGF-beta1 were not significantly different according to the concentrations of CsA. The expression of TIMP-1 was significantly increased at the CsA concentration of 500 ng/ml. CONCLUSION: We concluded that the gingival hyperplasia induced by CsA was more related with TIMP-1 than MMP-1 or TGF-beta1 on gingival collagen metabolism in patients treated with CsA.

PURPOSE: To investigate the general epidemiologic features of upper extremity fractures in children. MATERIALS AND METHODS: The records of the 589 in-patient children treated for upper extremity fractures over a 1-year period at 7 different hospitals were collected prospectively and analyzed. The severity of trauma was classified as slight, moderate or severe. This study examined the incidence of various upper extremity fractures and performed statistical analysis according to the epidemiologic parameters including age, gender and season. RESULTS: The average age of the children was 7.8 years. The average age of boys (8.5 years) was older than girls (6.4 years). The majority of fractures occurred at between 4 and 7 years of age (36%). The male to female ratio was approximately 2:1. The male predominance increased with age and increased dramatically in the age group, 12-16 years (5.8:1). The left side was injured more frequently (56%), and there was no difference between genders. The occurrence of fractures varied with the seasons with peaks in May (14.1%) and August (12.2%), and it was closely related to the temperature (r=0.778). The most common fractures were the supracondylar fractures of the humerus (32.6%), followed by distal radius fractures (18.2%), lateral condylar fractures (15.8%), radio-ulna shaft fractures (8%), clavicle fractures (4.2%), proximal humerus fractures (2.6%) and humerus shaft fractures (2.4%). Ninety seven percent of fractures were caused by a slight and moderate trauma. Fifty four percent of injured children underwent surgery, and 84% of operations were performed on the fractures around the elbow. CONCLUSION: This study examined the epidemiologic features of the upper extremity fractures in children.

Diabetes insipidus is an unusual cause of urinary frequency during pregnancy. It occurs in 2 to 6 per 100,000 pregnancies. It is a disorder in which the abnormal secretion, degradation, or activity of vasopressin cause hypotonic polyuria, polydipsia, and dehydration. And this syndrome appears to be associated with multiple gestations, preeclampsia, and abnormal liver function. We report two cases of pregnancies complicated with diabetes insipidus. One patient was diagnosed during pregnancy and DDAVP (L-deamino-8-d-arginine vasopressin) was used to manage diabetes insipidus. The other patient was diagnosed before pregnancy and DDAVP was not used.

The purpose of this research was to investigate whether pulsed electromagnetic field (PEMF) stimulation applied to the rabbit cranial defects grafted with beta-tricalcium phosphate (beta-TCP) could affect the new bone formation. With 16 New Zealand white rabbits under the same condition, bilateral calvarial bone defects were formed around the sagittal suture line. The defect on the left side was grafted with beta-TCP, while on the right side was grafted by harvested autogenous bone. PEMF was applied to 8 rabbits for 8 hours per day. The bony specimen were divided into 3 groups, the group 1 was autogenous bone grafted specimen, the group 2 was beta-TCP grafted with PEMF, and the group 3 was beta-TCP grafted without PEMF. We investigated the bone regeneration and growth factor expression at 2, 4, 6, and 8 weeks. As a result, BMP 2 was expressed in the group 1 from 2 weeks, the group 2 from 4 weeks, and the group 3 from 6 weeks. BMP 4 was expressed in the group 1 from 2 weeks, in the group 2 and the group 3 from 4 weeks. 4. There was no significant difference in expression pattern of BMP 7, PDGF, VEGF, and TGF-beta1 during grafted bone regeneration in group 1, 2, and 3. According to our results, PEMF stimulation could be effective on the new bome formation in animal study, and have a feasibility of clinical use.
