Extensive laceration of the lung itself has relatively little attention as a threat to life compared with other intrathoracic organ injuries. The incidence of pulmonary laceration extensive enough to require thoracotomy is rare, but is higher than expected. The diagnosis of extensive pulmonary laceration may be difficult, but this injury should be suspected with attention and early thoracotomy can be carried out in indicated cases. Recently, thoracoscopy has assumed a major role in the management of a variety of surgical diseases of the chest. We experienced a case of extensive pulmonary laceration caused by nonpenetrating trauma, which underwent lobectomy by thoracoscopic surgery. A 21-year-old man who was injured in a motocycle accident was brought to Emergency Room from the scene by an ambulance, and complained of chest pain and dyspnea. A chest roentgenogram showed a hemothorax and fractures of the posterior ends of the right seventh, eighth, and ninth ribs. A chest tube was inserted. Thirteen hundred ml of blood was drained through the chest tube during the next one hour. Emergency right mini-thoracotomy revealed extensive laceration of the lower lobe extending to the pulmonary hilum. The lower lobe was the most badly torn. A lower lobectomy was done by video-assisted thoracic surgery (VATS). He complained less postoperative pain and the postoperative course was uneventful.

PURPOSE: The purpose of this study was to compare the results of treatment of distal tibial fractures between intramedullary (IM) nailing and minimally invasive plate osteosynthesis (MIPO). MATERIALS AND METHODS: Between January 2007 and February 2012, 57 patients (57 cases) were treated for distal tibial fractures. Thirty-two patients (32 cases) were treated with IM nailing (nail group) and the 25 patients (25 feet) were treated with MIPO (plate group). Clinical results were compared using range of motion (ROM) of the ankle joint, American Orthopaedic Foot and Ankle Society (AOFAS) score, and Olerud-Molander score between nail group and plate group. Radiographic results were compared using mean bony union time, coronal and sagittal malunions, and shortening between the groups. RESULTS: Mean ROM of the ankle joint was significantly larger in nail group until 6 months after surgery; however, it was not different between two groups at the last follow-up. AOFAS score and Olerud-Molander score were not different between two groups at the last follow-up. In the nail group, two malunions more than 5 degrees were observed in coronal and sagittal planes, respectively. One case showed non-union in the plate group, however, bone union was obtained after autogeneous bone graft. CONCLUSION: Treatment using IM nailing is more advantageous in terms of postoperative rehabilitation than MIPO in distal tibial fractures.

BACKGROUND AND OBJECTIVES: For patients with bilateral carotid artery stenosis, simultaneous bilateral carotid endarterectomy is rarely performed due to a higher perioperative risk for death and strokes. We assessed the immediate and long-term outcomes of simultaneous bilateral carotid stenting (SBCS) for internal carotid stenosis in patients at high surgical risk. MATERIALS AND METHODS: We analyzed 10 patients who underwent SBCS for de novo stenoses of both internal carotid arteries (ICA). Included were those who had 60% to 99% stenosis of extracranial ICAs irrespective of neurologic symptoms and had more than 2 risk factors of Mayo grade III (medical risks) or IV (neurologic risks). RESULTS: The patients had a mean age of 67+/-7 years. Technical success was achieved in all lesions. The mean percent diameter stenosis was reduced from 79+/-13% to 8+/-8%. A total of 21 Wallstents were deployed at 20 lesions. One patient had a minor stroke just after the procedure which was completely resolved with local injection of urokinase. There were no deaths, major strokes or myocardial infarctions during the 30 day follow-up. Six months imaging studies were available on all 9 eligible patients with 18 lesions by duplex sonography and angiography. Late clinical follow-up at a mean of 15.1+/-8.1 months revealed no occurrence of neurologic event or death. CONCLUSION: SBCS is feasible, safe and effective to treat bilateral de novo ICA stenoses in patients at high surgical risk. The procedure, however, is investigational and more experience is required to define its role in the treatment of this patient population.

Postoperative infection from total knee arthroplasty (TKA) is an issue drawing great attention, which can manifest as a local or general infection. Its development into sepsis has also occasionally been reported. Such sepsis is a critical complication that can spread to various parts of the body, which can ultimately lead to mortality. However, the cases where infection has spread to the spine do not have clear clinical signs, making diagnosis difficult. These cases are not found in the literature. Therefore, this is a case study on both postoperative infection from TKA that has developed into sepsis and spread to the spine.

Purpose: The purpose of this study was to evaluate the wear and survival rates of third-generation ceramic heads on a conventional ultra-high molecular weight polyethylene liner. Materials and Methods: A total of 160 hips (147 patients with a mean age of 55.9 years) who underwent total hip arthroplasty using the third-generation ceramic head on a conventional polyethylene liner from March 1998 to August 2003 were reviewed retrospectively. Evaluation of the wear rate for 56 hips (49 patients) followed-up for at least 15 years was performed using the PolyWare program version 8 (Draftware Developers, USA). The Kaplan–Meier survivorship was also evaluated. Results: Linear wear and volumetric wear rates were 0.11±0.47 mm/year and 32.75±24.50 mm 3 /year, respectively. Nine revisions were performed during the follow-up period because of cup or stem loosening. The Kaplan–Meier survival rate, using cup revision or total revision total hip arthroplasty (THA) as the endpoint of analysis, was 93.7% at 15 years and 73.6% at 20 years. Conclusion Because all revisions were performed between 15 and 20 years in our study, surgeons should pay greater attention to patients who underwent THA with ceramic-on-polyethylene bearing from 15 years postoperatively. Contemporary alumina ceramic on highly cross-linked polyethylene could certainly be a good alternative bearing couple providing better longevity.

Takayasu's arteritis is a chronic inflammatory disease of unknown etiology involving the aorta, major branches of aorta, and pulmonary arteries and leads either stenosis and occlusion of the involved artery or aneurysm formation or both. The clinical course and prognosis are variable according to two major prognostic factors, ie, complications and the pattern of the past clinical course, as well as by ESR. Though the aggressive medical and surgical treatment are required for patients with a major complication and a progressive course, surgical reconstruction entails a high incidence of suture line complications including stenosis or dilatation. Moreover all the vascular lesions are amenable for vascular surgery. Initial reports revealed excellent results of percutaneous transluminal angioplasty (PTA) in patients with Takayasu's arteritis. However the suboptimal results and restenosis have been the main limitations of the PTA. Stenting has some benefits for early elastic recoil of the fibrotic vessels and restenosis as in other large vessels in Takayasu's arteritis or atherosclerosis. We report early and long-term results of two cases of carotid stenting in patients with symptomatic carotid stenosis and Takayasu's arteritis, which revealed variable angiographic results according to clinical courses and recommend that stenting in Takayasu's arteritis may be another treatment modality in inactive Takayasu's arteritis.

OBJECTIVES: Despite remarkable development of pharmacotherapy for schizophrenia, some patients continuously have had violence problems. The violence of psychotic patients is recently becoming the focus of the attention. The aim of this study is to investigate the influence of Cognitive Behavioral Therapy (CBT) on patients with schizophrenia having violence related history. METHODS: 15 Patients with schizophrenia spectrum disorder of crime history were treated with individual CBT for 12 sessions, and assessed with 4 scales (Korean version of Aggression Questionnaire, Korean version of the Barratt Impulsiveness Scale-11-Revised, Beck Cognitive Insight Scale and Positive and Negative Syndrome Scale) to evaluate anger, impulse, insight and clinical symptoms respectively at baseline and post treatment. The comparison group consisted of 15 patients with schizophrenia spectrum disorder of crime history. They were also assessed with the same scales during the same period. RESULTS: Although impulsivity is not changed significantly after treatment, but there was significant improvement in clinical symptom, insight and aggression, especially self-reflectiveness and anger respectively. CONCLUSION: CBT can be one of the good therapeutic tools for patients with schizophrenia having violence problems in that it reduces aggression and enhances insight of patients with schizophrenia spectrum disorder.

PURPOSE: High Outerbridge grade lesions of the articular cartilage have been associated with poor outcomes of high tibial osteotomy (HTO). However, there has been no report on the efficacy of HTO in the presence of kissing lesions. The purpose of this study was to compare clinical and radiographic outcomes of HTO between kissing lesion and non-kissing lesion groups. MATERIALS AND METHODS: Of the patients with medial compartment osteoarthritis and varus deformity treated with HTO between 2007 and 2012, 21 cases with kissing lesions and 22 cases without kissing lesions were selected. Clinical outcomes were assessed using the Lysholm knee scoring scale score, visual analogue scale score, Hospital for Special Surgery score, Western Ontario and McMaster Universities score, and Tegner activity score. Radiographic outcomes were assessed using the femoral-tibial angle, mechanical axis deviation, medial proximal tibial angle, posterior tibial slope angle, and joint space width. RESULTS: Clinical outcomes were improved in both groups from the postoperative assessment to the final follow-up, which showed no statistically significant difference between groups at the final follow-up. No statistically significant differences were observed with regard to radiographic assessment. CONCLUSIONS: Since both groups showed favorable short-term clinical and radiographic outcomes, HTO might be an alternative treatment option for degenerative osteoarthritis with kissing lesions in relatively young patients.

BACKGROUND AND OBJECTIVES: Otitis media is one of the most common diseases in otolaryngology, and the stapediovestibular joint could be influenced by the inflammation of the middle ear cavity. This study was performed in order to observe the changes of the stapediovestibular joint in experimentally induced otitis media. MATERIALS AND METHODS: Otitis media was induced by innoculation of Pseudomonas aeruginosa to the tympanic bullae of a guinea pig. The temporal bone was then removed after 1 week, 2 weeks, 4 weeks, and 7 weeks and observed with a light microscope. RESULTS: In the first week, many neutrophils and monocytes were aggregated in the middle ear cavity. The continuity of the middle ear mucosa was broken especially on the stapediovestibular joint, so the joint cavity was exposed. In the second week, inflammation remained. The mucosa of the middle ear cavity had thickened and the submucosal inflammatory cells were aggregated. In the fourth week, the inflammation was nearly subsided and the mucosa around the stapediovestibular joint was nearly normalized. In the seventh week, there was no evidence of the inflammation in the middle ear cavity and around the stapediovestibular joint. CONCLUSION: These findings suggest that the stapediovestibular joint could have been damaged by the inflammation in the middle ear, and that inflammation can influence the inner ear.
