Objective: Percutaneous vertebroplasty (VP) has been used for the safe treatment of osteoporotic compression fracture. However, cement leakage is the most common complication. To reduce the leakage of bone cement, we did the gelfoam embolization during VP. The purpose of this study is to compare the safety and feasibility of different two gelfoam embolization technique during VP. Methods: Total 127 patients (146 level) who had the thoracolumbar osteoporotic compression fracture were enrolled. Group A was treated by gelfoam-only technique and, Group B was treated by gelfoam with venography technique. We compared the incidence of bone cement leakage between two groups using post-operative computed tomography scan and X-ray. Results: Seventy-four patients (81 levels) were treated with gelfoam-only technique (A), and 53 patients (65 levels) were treated with gelfoam with venography technique (B). There were 22 leakages on group A, and 19 leakages on group B. There was no statistical significant difference between two groups (Chi-square test, p-value =0.958). Incidence of leakage to spinal canal was 11 levels in Group A, 3 levels in group B, and there was statistical significant difference (Fisher's exact test, p-value=0.027). Conclusion Complication induced by the bone cement leakage are the most careful point during VP. Gelfoam embolization with venography is very easy and safe method. Gelfoam with venography technique could make lower the incidence of cement leakage to spinal canal.

BACKGROUND: Few studies have investigated magnetic resonance (MR) characteristics of traumatic posterosuperior rotator cuff tears involving the supraspinatus and infraspinatus. We hypothesized that traumatic rotator cuff tears may have MR characteristics distinguishable from those of non-traumatic tears. METHODS: Preoperative MR arthrography and intraoperative tear size measurements were compared in 302 patients who underwent MR arthrography and subsequent arthroscopic rotator cuff repairs for traumatic (group T, 61 patients) or non-traumatic (group NT, 241 patients) tears. The inclusion criteria for both groups were posterosuperior full-thickness rotator cuff tear and age between 40 and 60 years. For group T, traumas were limited to accidental falls or slips, or sports injuries, motor vehicle accidents; injuries were associated with acute onset of pain followed by functional shoulder impairment; and time between injury and magnetic resonance imaging (MRI) was 6 weeks or less. RESULTS: In group T, 72.1% of shoulders (44 patients) had tendon tears with blunt edges while 27.9% of shoulders (17 patients) had tears with tapering edges. In contrast, 21.2% of patients in group NT (51 patients) had blunt-edge tears, while 78.8% (190 patients) of tears had tapering edges. These results were statistically significant (p<0.001) and estimated odds ratio was 9.6. The size of tear did not vary significantly between groups. CONCLUSIONS: We found no exclusive MR characteristic to define traumatic tears. However, oblique coronal MRI of traumatic tears showed a significant tendency for abrupt and rough torn tendon edges and relatively consistent tendon thicknesses (without lateral tapering) compared to non-traumatic cuff tears.

The chin plays a decisive role in the contour of the lower face. And harmonious jaw will correspond to good facial profile and positive image. Osseous genioplasty is a widely used method to correct the 3-dimensional(sagittal, vertical, tranverse) deformity of the chin with minimal complications. During an 8 year period from 1988, the authors at the In-Je University Seoul Paik Hospital experienced 198 patients of osseous genioplasty. Results of clinical analysis are as follows : 1) Male to female ratio was 1 : 3 with female being predoniment. The average age was 24.9 years. 2) Horizontal advancement genioplasty in 169 cases was the most common procedure with 7.0mm of average advancement. There was 4 cases of horizontal retrusion with average retrusion of 4.3mm. 52 cases had vertical augmentation with average of 7.5mm increase. 9 cases had vertical reduction with average redution of 4.9mm. 3) Although malocclusion is not necessarilly contraindication to genioplasty alone, genioplasty following surgical with or without orthodontical correction of malocclusion is the way to get better result with patient satisfaction. 4) 77% of the patients had adjunctive procedures simultaneously to acheive a better contour and profile 5) Complications such as hematoma, infection, fracture, nerve damage were minimal.

OBJECTIVE: We evaluate the rates and outcomes of major procedure-related complications during coiling. MATERIALS AND METHODS: Between 2007 and 2015, 436 intracranial saccular aneurysms were treated. Complications are categorized as three types: intraprocedural aneurysm rupture (IAR), thromboembolism (TE), and post-procedural early rebleeding (PER). And we evaluated the risk factors of procedure related complications by multivariate analysis. RESULTS: Complications occurred in 61 aneurysms (14%). The overall incidence of complications in subarachnoid hemorrhage (SAH) was significantly higher than in unruptured intracranial aneurysm (UIA) (20% vs. 6%). The incidence of IAR and TE were higher in SAH than in UIA (IAR 12% vs. 4%, TE 7% vs. 3%, p < 0.05). Five PER occurred only in SAH. In 34 UIA which were treated with balloon-assisted coiling (BAC), all these patients had good recovery despite 3 patients had the IAR. The incidence of IAR and TE were not different between BAC and non-BAC groups (p > 0.05). All 7 patients who had IAR during BAC had good recovery. In multiple logistic regression analysis, female gender, SAH, and intraventricular hemorrhage were associated with procedure related complication (p < 0.05). CONCLUSION: Endovascular coil embolization is a minimally invasive procedure, but incidence of its complication is not low, especially in SAH. BAC can be a good tool to avoid poor outcome from unexpected IAR during coiling. While IA tirofiban injection is a useful therapy in TE during coiling, sometimes we are aware of the risk of the early rebleeding in SAH patients.

We evaluated the effect of the pregnane X receptor agonist, pregnenolone 16 alpha-carbonitrile (PCN) on the expression levels of plasma monoamine transporter (PMAT) in the intestine. Male C57/BL6 mice were divided into two 2 groups: mice in the PCN group (n=3) were administered PCN once a day for 4 days, while those in the control group (n=3) received the same volume of vehicle once a day for 4 days. After the mice were killed 24 h after administration of the last dose of PCN or vehicle, and the expression levels of PMAT in the intestine tissues were isolated and measured the expression level of PMAT using immunohistochemical and western blotting analyses. The expression level of PMAT expression levels in the small intestine increased after PCN treatment. These results suggest that the induction of PMAT may play a clinically significant role by increasing intestinal absorption of PMAT substrates such as metformin.
