Percutaneous vertebroplasty is a relatively recent procedure in the treatment of osteoporotic vertebral compression fractures. Bone cement embolism is a severe and potentially life-threatening complication of percutaneous vertebroplasty with cement. The risk for cement pulmonary embolism ranges between 3.5 and 23% for osteoporotic fractures. Bone cement leakage may be usually more frequent with vertebroplasty than with kyphoplasty. We experienced a 69-year-old female patient of an asymptomatic pulmonary embolus (length 8 cm) after kyphoplasty for an osteoporotic vertebral compression fracture

Symptomatic aneurysmal bone cysts with expansible lesions in the pelvis are rare in children. The management of an aggressive vascular lesion in a female child is challenging. The standard treatment for aneurysmal bone cysts is accompanied by a high risk of local recurrence. A 12-year-old female presented with a history of pelvic pain for 5 months. Plain radiographs and magnetic resonance imaging showed a very large expansile lytic lesion arising from the right iliac bone. Intralesional curettage, electric cauterization, chemical sclerotherapy and allogeneic bone graft were performed through the window of the iliac crest. At a follow-up consultation 3.5 years post-surgery, the child had painless full-range movement in the hip joint with no recurrence. Although many treatment options are described, our patient was treated successfully using curettage and allogeneic bone graft without recurrence.

Achondrogenesis type 2 is a lethal form of congenital skeletal dysplasia characterized by severe short-limbed dwarfism, decreased vertebral ossification and normal ossification of the skull. We report an autopsy case of achondrogenesis type 2 in a female fetus terminated at 29 weeks of gestation. External morphology revealed a relatively large head, short upper and lower extremities, short neck, and distended abdomen. The x-ray finding showed normal calvarial ossification, hypoplastic ilium and unossified ischium, and metaphyseal flares of the femur and tibia. Histologically, chondrocytes were large and irregular with increased vascularity.

There is no single characteristic clinical or radiological feature to diagnose xanthogranulomatous pyelonephritis, so it makes accurate preoperative diagnosis difficult. In our case, the renal parenchyme of affected kidney was well preserved on excretory urogram. The abnormal finding was only a filling defect within the right upper pelvocalyceal system. Herein we report a case of xanthogranulomatous pyelonephritis in a 18 years old girl which was confused with renal pelvic tumor.

While a sprain of the hamstring muscle is relatively common in athletes or those who participate in physically active sports, a complete rupture of the proximal hamstring is relatively rare. A rupture of the long head of the biceps femoris without rupture of the semimembranosus and semitendinosus muscles has rarely been reported. In this study, we saw relatively favorable outcomes after reattachment with a suture anchor at the ischial tuberosity in two patients who had a rupture of the long head of the biceps femoris.

Retmperitoneal neurilemmoma are exceedingly rare and difficult to diagnose both pre- and post- operatively. The vast majority arise in cranial nerve, with occasional occurrence in nerve of extremity, and only rare presentation in retroperitoneum. We report here a case of retroperitoneal neurilemmoma in a 38-year-old woman, which was confused with lymphosarcoma.

BACKGROUND: The purpose of this study was to calculate the measurement uncertainty of the process of bone mineral density (BMD) analysis using dual energy X-ray absorptiometry with traceability. METHODS: Between March 2015 and October 2016, among healthy participants in their 20s and 30s, the study included those who had not taken calcium, vitamin D supplements and steroids and were without a history of osteoporosis, osteopenia and diseases related to osteoporosis. Relational expression of the model was established based on Guide to the Expression of Uncertainty in Measurements and Eurachem and the uncertainty from each factor was evaluated. RESULTS: The combined standard uncertainty was 0.015, while the expanded uncertainty was 0.0298. The factor-specific standard uncertainties that occurred in the process of measuring BMD were 0.72% for the calibration curve, 0.9% for the internal quality control (IQC) using Aluminum Spine Phantom, 0.58% for European Spine Phantom (ESP), and 0.9% for the inspector precision (IP). CONCLUSIONS: The combined standard uncertainty of the spine BMD corrected with ESP was 0.015 when measured at one time and targeting one participant. The uncertainties of the accuracy of the IQC and the IP were higher than that of the other factors. Therefore, there will be a need for establishment of protocols to lower these uncertainties.

BACKGROUND: Opioids are known to increase the incidence of postoperative nausea and vomiting (PONV). Remifentanil is an ultrashort-acting opioid with a potent analgesic effect and is useful for rapid emergence. This study compared the effect of remifentanil on the incidence and severity of PONV and postoperative pain with that of fentanyl in patients undergoing laparoscopic surgery, which is normally associated with a high incidence of PONV. METHODS: Forty-four adult female patients, who were scheduled for laparoscopic ovarian cyst enucleation, were randomly assigned to either the remifentanil or fentanyl group. Anesthesia was induced with propofol after injecting fentanyl 2 microgram/kg or remifentnail 1 microgram/kg and was maintained with sevoflurane. Remifentanil and fentanyl was infused continuously in the range of 0.2-0.5 microgram/kg/min and 0.03-0.05 microgram/kg/min, respectively. Ketorolac 0.5 mg/kg was injected 30 min before the end of surgery. The incidence and severity of PONV and pain were recorded upon arrival at the recovery room and 2, 6, 12 and 24 hours thereafter. RESULTS: The incidence and severity of PONV and pain were significantly higher in the remifentanil group upon arrival at the recovery room than in the fentanyl group. The incidence and severity of PONV and pain at the other measurement times were similar. CONCLUSIONS: Despite the ultrashort action duration of the remifentanil, the incidence and severity of PONV and postoperative pain immediately after awakening was higher in the remifentanil group undergoing laparoscopic ovarian cyst enucleation than in the fentanyl group. However, there were no significant differences after two hours in the recovery phase.
