Objective: Conflicting results regarding SOX17 genes and the risk of intracranial aneurysms (IA) exist in the Korean population, although significant positive correlations were noted in genome-wide association studies in European and Japanese populations. Therefore, we aimed to investigate an association between SOX17 gene variants and IA using exome sequencing data. Methods: This study included 26 age-gender matched IA patients and 26 control subjects. The SOX17 gene variants identified from whole-exome sequencing data were examined. Genetic associations to estimate odds ratio (OR) and 95% confidence interval (CI) were performed using the software EPACTS. Results: The mean age of the IA and control groups were 51.0±9.3 years and 49.4±14.3 years, respectively (p=0.623). Seven variants of SOX17, including six single nucleotide polymorphisms and one insertion and deletion, were observed. Among these variants, rs12544958 (A>G) showed the most association with IA, but the association was not statistically significant (OR, 1.97; 95% CI, 0.81-4.74; p=0.125). Minor allele frequencies of the IA patients and controls were 0.788 and 0.653, respectively. None of the remaining variants were significantly associated with IA formation. Conclusion No significant association between SOX17 gene variants and IA were noted in the Korean population. A large-scale exome sequencing study is necessary to investigate any Korean-specific genetic susceptibility to IA.

The authors report a patient with a small traumatic cirsoid aneurysm of the scalp, diagnosed by duplex doppler ultrasonography. This 15-year-old boy was diagnosed as a cirsoid aneurysm by duplex doppler ultrasonogram which revealed an ovoid cystic lesion at left temporal area of scalp containing vascular flow mapping. The gross appearance showed an aneurysm with arteriovenous fistula, consisting of two feeding arteries and two draining veins. Total removal of mass was made and the histological examination revealed an aneurysm which showing irregular contour of inner surface and thickened fibrotic vascular wall without normal arterial layers. Noninvasive duplex doppler ultrasonography before surgical excision or direct puncture embolization of cirsoid aneurysms of the scalp could be recommended as an alternative management option.

The purpose of this study was to present the clinical result of anterolateral thigh free flap for pretibial soft tissue lesion after chronic tibia osteomyelitis. From December 2006 to September 2008, Five patients were included in our study. 4 of 5 were superficial or localized types of chronic tibia osteomyelitis, based on the classification of Cierny and Mader. Average age at the surgery was 45 years, three were males and two were females. All had a history of chronic tibia osteomyelitis and subsequent pretbial soft tissue lesions coming from previous operations or pus drainage. Pretibial soft tissue defects included small ulcers, fibrotic, bruisable soft tissue and small bony exposures, but not large-sized bony exposures nor active pus discharge. After complete debridement of large sized pretibial soft tissue lesions and decortication of anterior tibial cortical dead bone, anterolateral thigh free flap was applied to cover remained large pretibial soft tissue defect and to prevent the recurrence of infection. All flaps survived and provided satisfactory coverage of soft tissue defect on pretibial region for 16 months' mean follow up period. No patients has had recurrence of osteomyelitis. Anterolateral thigh free flap could be recommend for large sized pretibial soft tissue defect of supreficial or localized types of chronic tibia osteomyelitis after through debridement.

The purpose of this study was to present the clinical significance of rectus abdominis free muscle flap for large sized diabetic ulcer and necrosis of the foot to salvage limb. From June 2000 to February 2006, eleven patients were included in our study. There were seven males and four females with a mean age of 58.3 years (48~65) at the surgery. All had a history of diabetics and subsequent huge soft tissue defect caused by necrotizing abscess formation around the foot and the ankle. After complete debridement of large sized, infected necrotic tissue, susceptible intravenous antibiotics and wound care were done. After control of infection, confirmed by clinical and laboratory findings, the rectus abdominis free muscle flap was applied to cover remained large soft tissue defect and to prevent the recurrence of infection. All flaps survived and it provided satisfactory coverage for the soft tissue defect on the foot and the ankle area for a mean of 41.1 months (24~85) follow up period. All except of one patients did not have any recurrence of infection on the operation site and could salvage their limbs. The rectus abdominis free muscle flap could be recommended for large sized soft tissue defect after necrotizing abscess in diabetic foot to salvage major limb.

PURPOSE: Previous lumbar spinal surgery (PLSS) is not currently considered as a contraindication for regional anesthesia. However, there are still problems that make spinal anesthesia more difficult with a possibility of worsening the patient's back pain. Spinal anesthesia using combined spinal-epidural anesthesia (CSEA) in elderly patients with or without PLSS was investigated and the anesthetic characteristics, success rates, and possible complications were evaluated. MATERIALS AND METHODS: Fifty patients without PLSS (Control group) and 45 patients with PLSS (PLSS group) who were scheduled for total knee arthroplasty were studied prospectively. A CSEA was performed with patients in the left lateral position, and 10 mg of 0.5% isobaric tetracaine was injected through a 27 G spinal needle. An epidural catheter was then inserted for patient controlled analgesia. Successful spinal anesthesia was defined as adequate sensory block level more than T12. The number of skin punctures and the onset time were recorded, and maximal sensory block level (MSBL), time to 2-segment regression, success rate and complications were observed. RESULTS: The success rate of CSEA in Control group and PLSS group was 98.0%, and 93.3%, respectively. The median MSBL in PLSS group was higher than Control group [T4 (T2-L1) vs. T6 (T3-T12)] (p < 0.001). There was a significant difference in the number of patients who required ephedrine for the treatment of hypotension in PLSS group (p = 0.028). CONCLUSION: The success rate of CSEA in patients with PLSS was 93.3%, and patients experienced no significant neurological complications. The MSBL can be higher in PLSS group than Control group.

STUDY DESIGN: Retrospective study. PURPOSE: To evaluate the relationship between a new osteoporotic vertebral fracture and instrumented lumbar arthrodesis. OVERVIEW OF LITERATURE: In contrast to the growing recognition of the importance of adjacent segment disease after lumbar arthrodesis, relatively little attention has been paid to the relationship between osteoporotic vertebral fractures and instrumented lumbar arthrodesis. METHODS: Twenty five patients with a thoracolumbar vertebral fracture following instrumented arthrodesis for degenerative lumbar disorders (study group) were investigated. The influence of instrumented lumbar arthrodesis was examined by comparing the bone mineral density (BMD) of the femoral neck in the study group with that of 28 patients (control group) who had sustained a simple osteoporotic vertebral fracture. The fracture after instrumented arthrodesis was diagnosed at a mean 47 months (range, 7 to 100 months) after the surgery. RESULTS: There was a relatively better BMD in the study group, 0.67 +/- 0.12 g/cm2 compared to the control group, 0.60 +/- 0.13 g/cm2 (p = 0.013). The level of back pain improved from a mean of 7.5 +/- 1.0 at the time of the fracture to a mean of 4.9 +/- 2.0 at 1 year after the fracture (p = 0.001). However, 12 (48%) patients complained of severe back pain 1 year after the fracture. There was negative correlation between the BMD of the femoral neck and back pain at the last follow up (r = - 0.455, p = 0.022). CONCLUSIONS: Osteoporotic vertebral fractures after instrumented arthrodesis contribute to the aggravation of back pain and the final outcome of degenerative lumbar disorders. Therefore, it is important to examine the possibility of new osteoporotic vertebral fractures for new-onset back pain after lumbar instrumented arthrodesis.

STUDY DESIGN: This is a retrospective study that was done according to clinical and radiological evaluation. PURPOSE: We analyzed the clinical and radiological outcomes of minimally invasive transforaminal lumbar interbody single level fusion. OVERVIEW OF LITERATURE: Minimally invasive transforaminal lumbar interbody fusion is effective surgical method for treating degenerative lumbar disease. METHODS: The study was conducted on 56 patients who were available for longer than 2 years (range, 24 to 45 months) follow-up after undergoing minimally invasive transforminal lumbar interbody single level fusion. Clinical evaluation was performed by the analysis of the visual analogue scale (VAS) score and the Oswestry Disability Index (ODI) and the Kirkaldy-Willis score. For the radiological evaluation, the disc space height, the segmental lumbar lordotic angle and the whole lumbar lordotic angle were analyzed. At the final follow-up after operation, the fusion rate was analyzed according to Bridwell's anterior fusion grade. RESULTS: For the evaluation of clinical outcomes, the VAS score was reduced from an average of 6.7 prior to surgery to an average of 1.8 at the final follow-up. The ODI was decreased from an average of 36.5 prior to surgery to an average of 12.8 at the final follow-up. In regard to the clinical outcomes evaluated by the Kirkaldy-Willis score, better than good results were obtained in 52 cases (92.9%). For the radiological evaluation, the disc space height (p = 0.002), and the whole lumbar lordotic angle (p = 0.001) were increased at the final follow-up. At the final follow-up, regarding the interbody fusion, radiological union was obtained in 54 cases (95.4%). CONCLUSIONS: We think that if surgeons become familiar with the surgical techniques, this is a useful method for minimally invasive spinal surgery.

Charcot-Marie-Tooth disease (CMTD) comprises a group of disorders characterized by progressive distal muscle weakness and atrophy. We report the management of a 37-year-old multigravida with CMTD scheduled for Cesarean section. The combined spinal-epidural anesthesia was selected as the anesthetic management and postoperative pain control. Mother and baby had an uneventful recovery and they discharged home on the seventh postoperative day. Combined spinal-epidural anesthesia is thought to be a safe and effective method of anesthesia for Cesarean section in a patient with CMTD.

Coccygodynia is a common problem that is characterized by pain in the tailbone that radiates to the lower sacral and perineal areas. Coccygodynia may occur after a fall in the sitting position or damage to the sacrococcygeal ligament during a difficult vaginal delivery.Currently, the therapeutic options for coccygodynia are unclear, however, a number of treatment approaches have been proposed.In this case a favorable outcome was obtained by using a radiofrequency lesion generator to create a lesion on the ganglion impar in a patient with chronic coccygodynia.
