Background: There have been an increasing number of reports about infection-related complications after epidural block, and the analysis of these previous reports may offer valuable information for the prevention and treatment of such complications. Methods: We searched for complications about infection that was related to epidural blockade procedures by using the Medline Search program. We analyzed the types of infection-related complications as well as the potential risk factors, the time course from symptom development to treatment, the causative organisms and the treatment outcomes. Results: Seventeen cases were identified. The types of complications were epidural abscess, subdural abscess, spinal arachnoiditis, bacterial meningitis and aseptic meningitis. Five patients received a single block and twelve patients received a continuous block with catheterization. The most common site of epidural catheterization was the lumbar area and eight patients had indwelling catheters for less than fifteen days. Eight patients had a diabetes mellitus as a risk factor and fourteen patients showed less than seven days from the development of symptoms to treatment. Eleven patients received laminectomy and intravenous antibiotics as a treatment and eight patients had full recovery without neurological deficit. Conclusions: Early diagnosis and treatment is essential for the favorable outcome of infection-related complication after epidural block. In addition, absolute sterile technique should always be performed and patient education concerning these potential complications must be accompanied.

Sorafenib is indicated for the treatment of advanced hepatocellular carcinoma (HCC), but although rare, tumor lysis syndrome (TLS) can be fatal in HCC patients with a large tumor burden. The authors describe the case of a 55-year-old hepatitis B carrier who visited our clinic with progressive dyspnea for 3 weeks. Chest and abdominal computed tomography revealed a huge HCC in the left lobe of the liver with invasion of the inferior vena cava, right atrium, and pulmonary arteries. After 8 days of sorafenib administration, TLS was diagnosed based on the characteristic findings of hyperuricemia, hyperkalemia, and acute kidney injury with massive tumor necrosis by follow-up imaging. Despite discontinuation of sorafenib and supportive care, the patient's clinical course rapidly deteriorated. The authors describe a rare but fatal complication that occurred soon after sorafenib initiation for HCC. Careful follow-up is required after commencing sorafenib therapy for the early diagnosis and management of TLS.

In this report, we present a rare case of solid silicone implant displacement to the contralateral side after aesthetic gluteal augmentation, a phenomenon that has never been reported before in the literature. A 29-year-old woman with a history of gluteal augmentation 9 months previously and soft tissue infection presented for a consultation due to 3 days of sudden progressive pain in the right gluteus with erythema and edema, without a history of trauma. Displacement of the left gluteal implant to the right gluteal pocket was shown by magnetic resonance imaging. Because the patient refused implant removal, the decision was made to perform capsulotomy, to reconstruct the gluteal pockets, and to preserve the implants. The patient showed a satisfactory early and late postoperative course. Possible causes of this complication include poor surgical technique, with insufficient tissue preservation to keep the pockets apart, and the presence of seroma or hematoma that favored an infectious process, thereby leading to deterioration of the dissected soft tissues with dehiscence of the wound favoring the displacement of the implant.

Background: To report the radiological and clinical outcomes of internal fixation using distal clavicle hook plates for distal clavicle fractures. Methods: From April 2008 to December 2012, 32 patients with distal clavicle fractures underwent surgery using an AO hook plate. The reduction was qualified and evaluated according to the radiological findings. The evaluation of the clinical outcomes was performed with the University of California at Los Angeles (UCLA) score, the Korean Shoulder score, and the visual analogue scale (VAS) pain score. Results: By radiological evaluation, we found that 31 of 32 patients showed anatomical reduction and solid bone union. Although we obtained satisfactory UCLA scores, Korean Shoulder Scale scores, and VAS pain scores, 12 cases of complications were present. We found 4 cases of osteolysis of the acromion, 1 case of nonunion, 3 cases of periprosthetic fractures, 3 cases of subacromial pain, and 1 case of skin irritation. We performed re-operations in 2 patients. Conclusions: To avoid complications associated with clavicle hook plates, choosing the appropriate hook size and bending of the hook according to the slope of the acromion undersurface is critical. Also, we believe that early removal of clavicle plates may help reduce complications.

An esophageal perforation following anterior cervical fusion is rare. Early development of an esophageal perforation after anterior cervical fusion is usually due to iatrogenic injury from retraction, injury associated with the original traumatic incident, improperly placed instruments or a bone graft. A 31-year-old man had a cervical dislocation and spinal cord injury because of severe cervical trauma after a traffic accident. He was quadriplegic and had no feeling below T4 dermatome. Anterior decompression of the cervical spine and anterior fusion with mesh with autobone were performed. An esophagocutaneous fistula occurred 7 days after anterior cervical surgery. A second anterior surgery was done because of pus drainage. The mesh was changed with an iliac bone graft, and the esophagocutaneous fistula site was primary repaired, but pus continued to drain. Conservative treatment, which consisted of wound drainage and intravenous administration of antibiotics, was tried, but was unsuccessful. After all, we removed the plate and screws, but did not removed the iliac bone graft, We closed the esophageal fistula, and transposed the sternocleidomastoid muscle flap to the interspace between the esophagus and the cervical spine. The wound to the esophagus was well repaired. In conclusion, precautionary measures are needed to avoid the complication, and adequate treatment is necessary to resolve those complications when they occur.

Injuries to the major vessels in the thoracic inlet require early recognition and expedient operative approach. Delayed diagnosis difficulties encountered in the operative exposure of the region are the major factors limiting successful management. This report is a review of 13 patients with vascular injuries to the neck base who were managed at Busan National University Hospital from March 1975 to September 1978 about 3 years and 6 months. The important clinical problems are delineated with emphasis on the technical aspects of operative management. 1] Among 13 cases, 8 cases were male 5 cases were female. 2] Of 28 vascular injuries, subclavian axillary vascular injuries were 22 [78%]. Stab wound was the cause in 70% of these patients. 3] Without extension 7 cases[53.8%] were managed successfully with supraclavicular, and axillary incision. Posterolateral thoracotomy one of extending 4 cases, 2 cases were used right musculoskeletal flap for management of proximal part of the subclavian artery and innominate vessel, 2 cases were used left supraclavicular incision with anterolateral thoracotomy for management of left proximal subclavian artery. One Expired. 4] Repair of vascular injury was accomplished by lateral suture of debridement and end-to end anastomosis in 17[74%]. Autogenous vein was used one for interposition graft. Ligation was required 2 arterial, 6 venous injuries. Of 8 cases which were pulseless preoperatively, 5 cases were able to palpable distal pulse. 5] Post operative complications occurred 50%. Complication of vasular repair was rare. The majority was neurologic deficit (33.3%).

A cerebral fat embolism is an uncommon but serious complication of long bone fracture. It can be fatal, and early detection is not easy. Neurologic symptoms are variable, and the clinical diagnosis is difficult. The pathogenesis remains controversial, and several theories have been proposed. Magnetic resonance imaging can detect a cerebral fat embolism with a higher sensitivity than cerebral computed tomography. We report a case of a posttraumatic cerebral fat embolism without pulmonary involvement and review the existing literature.

Improved clinical performance was expected from the introduction of the low-profile model of the Ionescu-Shiley pericardial valve. The long-term clinical results were assessed on the consecutive 47 patients who underwent MVR + AVR with this valve between 1984 and 1988. Three patients died within 30 days of surgery[operative mortality, 6.4%], and 44 early survivors were followed up for a total of 203.8 patient-years [Mean + SD, 4.63 + 1.47 years]. One died during the follow-up with a linearized late mortality of 0.491%/patient~year[pt-yr]. None experienced thromboembolism. Bleeding and endocardiris were seen in each single patient with the incidences of complication of 0.491%/pt-yr respectively. The linearized rate of primary tissue failure [PTF] was 0.491%/pt-yr. The actuarial survival and rate of freedom from PTF were 97.6 _+ 2.4% and 92.6 +7.1% at 7 years of follow-up.These results are favorably comparable with the ones seen in the patients of MVR + AVR with the standard profile lonescu-Shiley valve in all respects except the higher mean age of the low-profile group. Although the clinical performance was compatible with other major reports, the durability of the valve remains to be proved with the prolonged follow-up.

Between October, 1978, and December, 1982, Glutaraldehyde-stablized pericardial xenografts [Ionescu-Shiley valve] were used for heart valve replacement in 409 patients.[251 mitral, 49 aortic, 11 tricuspid, and 98 multiple valve replacement]. There were 31 early deaths [7.6%], and 371 operative survival were observed for a total of 507.6 years over a period of 1 to 44 months. [mean 17 months]. Actuarial analysis of late results indicates an excepted survival rate at 4 years of 86.25.4% for patients with mitral, 79.37.1% for patients with aortic valve replacement. Actuarial survival rates for total patients at 4 years was 77.88.2%. The rate of systemic embolism has been 1.6% per patient-year for mitral and 1.8% per patient-year for aortic group in the presence of anticoagulation treatment. Among the 6 embolic episodes, 2 patients were died. The incidence of hemorrhagic complication was 1.3% per patient-year for anticoagulated patients. There were 6 confirmed valve failures, five in mitral and one in aortic position. Re-replacement of destructed valve was performed in one patient and others were treated medically. Among the 6 episodes, 3 occurred in children [Below 15 years], it account almost 9 times higher than adult. Our clinical data compare very favorable with those obtained with other available prostheses and tissue valves, but it should be considered to give short-term anticoagulation therapy to hemodynamically stable patients and aortic valve patients, and other prosthetic valve must be considered to use in children.

The aim of this study was to systematically investigate the complications of single implant-supported restorations followed more than 5-year. Thirty-five studies were selected for the systematic review. A total of 3932 single implants were included at the beginning of studies. Thirty-one implants were removed before loading and 91 implants after loading. The overall implant loss rate was 3.1 %. Implant losses were concentrated on the period between loading and 2-year follow-up, and, after a stable period, increased after 5-year follow-up. The mean marginal bone loss at single-tooth implants was well within 0.2 mm/year, i.e., acceptable annual bone loss by the implant success criteria. However, considerable amounts of single implants suffered a marginal bone loss at implant more than 0.2 mm/year. Fistula was a frequent biological complication in the early studies. The most frequent technical problem was a screw loosening, but its frequency was reduced after the use of a gold screw and torque controller. Within the limits of this study, the complications of single implants might be underestimated due to the lack of information about the biological and technical complications available in the relevant literature.
