Objective : The purpose of this study was to compare the results of three types of short segment screw fixation for thoracolumbar burst fracture accompanying osteopenia. Methods : The records of 70 patients who underwent short segment screw fixation for a thoracolumbar burst fracture accompanying osteopenia (-2.5< mean T score by bone mineral densitometry <-1.0) from January 2005 to January 2008 were reviewed. Patients were divided into three groups based on whether or not bone fusion and bone cement augmentation procedure 1) Group I (n=26) : short segment fixation with posterolateral bone fusion; 2) Group II (n=23) : bone cement augmented short segment fixation with posterolateral bone fusion; 3) Group III (n=21) : bone cement augmented, short segment percutaneous screw fixation without bone fusion. Clinical outcomes were assessed using a visual analogue scale and modified MacNab's criteria. Radiological findings, including kyphotic angle and vertebral height, and procedure-related complications, such as screw loosening or pull-out, were analyzed. Results : No significant difference in radiographic or clinical outcomes was noted between patients managed using the three different techniques at last follow up. However, Group I showed more correction loss of kyphotic deformities and vertebral height loss at final follow-up, and Group I had higher screw loosening and implant failure rates than Group II or III. Conclusion : Bone cement augmented procedure can be an efficient and safe surgical techniques in terms of achieving better outcomes with minimal complications for thoracolumbar burst fracture accompanying osteopenia.

Objective : We compared the results of two surgical techniques by retrospective study of 60 elderly patients (65 years or older) who underwent either decompression alone or fusion for the treatment of two-level or more lumbar spinal stenosis. Methods : During the period of 2003 and 2008, two-level or more decompression alone or fusion was performed for lumbar spinal stenosis by three surgeons at our institution. Patients were allocated to two groups by surgical modality, namely, to a decompression group (31 patients) or a fusion group (29 patients). Overall mean age was 71.1 years (range, 65-84) and mean follow-up was 5.5 years (range, 3-9). A retrospective review of clinical, radiological, and surgical data was conducted. Results : No significant difference between the two groups was found with respect to age, follow-up period, surgical levels, or preoperative condition. At the last follow-up, correction of lumbar lordotic angle (determined radiologically) was better in the fusion group. However, clinical outcomes including visual analogue scale, Oswestry Disability Index, and the Odom's criteria were not significantly different in the two groups. On the other hand, surgical outcomes, such as, operation time, estimated blood loss, and surgical complications were significantly better in the decompression alone group. Conclusion : Our findings suggest that decompressive laminectomy alone achieves good outcomes in patients with two-level or more lumbar spinal stenosis, associated with an advanced age, poor general condition, or osteoporosis.

Background: Lung cancer is the most frequent cancer among men and second highest among women overall, including in Turkey. Cigarette smoking is the most important etiologic factor for the development of cancer in both men and women. Objective: To determine the lung cancer incidence in Northeastern Anatolia Region of Turkey with a focus on clinical properties, cancer subtypes, the relationships of tumors with cigarette smoking and radiological properties of the lesions. Materials and Methods: In a retrospective study design, 566 lung cancer cases diagnosed at the Pathology Department of Ataturk University in Erzurum over the last seven years extending from January 2006 to June 2012 were investigated. The results were compared with statistical analyses. Results: The most common histopathological subtype of primary bronchogenic carcinoma in our study was found to be the squamous cell carcinoma, 46.1% (261 out of 566), and the second was small cell lung carcinoma 15.7% (89 out of 566). Based on our data, an overall male predominance was noted with a male/female ratio of 6.1/1. While 296 (52.2%) of the patients were found to be smokers at the time of diagnosis, 125 (22.0%) were nonsmokers and 145 (25.6%) were ex-smokers. Smoking status was found to have a strong correlation with primary lung cancer (p<0.05), and there were significant differences between males and females (p<0.001). Conclusion: Although relative prominence of subtypes of lung cancers differ between Turkish and other populations, lung cancer overall remains as an important health problem in Turkey. Our findings stress the critical need for effective cancer prevention programs such as anti-smoking campaigns.

Purpose: We investigate the characteristic morphologic features and suggest proper treatment of postaxial polydactyly of the foot Materials and Methods: We analysed 37 cases of postaxial polydactyly. Mean post operative follow up period was 2 years 10 months. We analysed them according to morphological, radiological and operative findings. Patients were classified into extra 5th toe polydactyly and extra 6th toe polydactyly based on the abnormal extradigit, and subdivided into joint origin type, bone origin type and floating type based on duplication pattern. Results: 23 cases were extra 5th toe polydactyly and 14 cases were extra 6th toe polydactyly. Most common types were metatarsophalangeal joint origin type of extra 6th toe polydactyly. Compared with extra 5th toe polydactyly, extra 6th toe polydactyly originated from more proximal part and had not syndactylism. Conclusion: As the duplication level was more distal, degree of syndactylism and nail union was more severe. In case of syndactyly between 5th and 6th toe, abnormal extradigit was 5th toe.

Purpose: We conducted this study to examine the clinical results of the proximal metatarsal wedge osteotomy using a single screw fixation and the distal soft tissue procedure in patients with moderate to severe hallux valgus deformity. Materials and Methods: Between February 2002 and February 2004, we performed these procedures on 12 patients (15 cases). The 6 cases of all patients had mild to moderate instability in the first MTC (metatarsocuneiform) joint. We estimated the clinical outcomes, the radiological findings and complications. Results: AOFAS score was improved from preoperative 41.5 points to 87.7 points lastly on average. The mean correction angle of HVA and IMA was $23.8^{\circ}$ and $6.6^{\circ}$, respectively. The mean position of tibial sesamoid was 2.67 before surgery and 0.87 after surgery. The mean shortening of the first metatarsal bone was 3.07 mm after surgery. There was no pain and complications on the first MTC joint except the breakage of screw in one case and instability of the first MTC joint was improved postoperatively. Conclusion: We obtained good clinical and radiographic outcomes in our series. So, proximal metatarsal wedge osteotomy using a single screw fixation and distal soft tissue procedure seems one of the good surgical treatments for moderate hallux valgus deformity.

Debates exist about the appropriate treatment for pancreatic trauma in children. We intended to examine the safety of the operation of pancreatic trauma in children. This is a retrospective study of 13 patients, younger than 15, who underwent surgery for pancreatic trauma, between 1993 and 2011 in Seoul National University Children's Hospital. Medical records were reviewed for mechanism of trauma, clinical characteristics, radiological findings, operation and outcomes. Organ injury scaling from the AAST (American Association for Surgery of Trauma) was used. All injuries were caused by blunt trauma. Patients with grade III, IV, and those who were difficult to distinguish grade II from IV, underwent surgery due to severe peritonitis. Three patients with grade II were operated for reasons of mesenteric bleeding, tumor rupture of the pancreas, and progression of peritonitis. Distal pancreatectomy was performed in 10 patients and subtotal pancreatectomy and pylorus preserving pancreaticoduodenectomy in 1 patient each. The remaining one underwent surgical debridement because of severe adhesions. The location of injury, before and after operation, coincided in 83.3%. The degree of injury, before and after the operation, was identical in all the patients except for those who were difficult to tell apart grade II from grade IV, and those cannot be graded due to severe adhesion. Postoperative complications occurred in 23.1%, which improved with conservative treatment. Patients were discharged at mean postoperative 12(range 8~42) days. Even though patients with complications took longer in time from diagnosis to operation, time of trauma to operation and hospital stay, this difference was not significant. In conclusion, When pancreatic duct injury is present, or patient shows deterioration of clinical manifestation without evidence of definite duct injury, or trauma is accompanied by other organ injury or tumor rupture, operative management is advisable, and we believe it is a safe and feasible method of treatment.

Diffuse panbronchiollitis (DPB), a rare progressive disorder, has lately been receiving increasing attention. DPB is a disease of obscure etiology, characterized by chronic inflammation localized mainly in the region of respiratory bronchiole just distal to the terminal bronchioles. In 1983, Homma and coworkers reported 82 cases of a new clinicopathological entity, DPB, in Japan. Also DPB is a disease largely restricted geographically to Japan but the prevalence in other countries is extremely low. Histoloically, it is characterized by a suppurative bronchiolitis involving primarily the respiratory and terminal bronchioles with subsequent progression to bronchiectasis. The disease progresses rapidly and results in respiratory failure due to repeated respiratory infections. We experienced a cases of DPB accompanied with chronic maxillary sinusitis in both sinuses. Diagnosis of DPB was comfirmed by pathological results from thoracoscopic lung biopsy, typical radiological findings, clinical symptoms and pulmonary function test. After treatment with erythromycin for 6 months, the patient's condition and the typical micronodular densities on the chest radiography improved. A few case of DPB was reported in Korea. We report a case of DPB through thoracoscopic lung biopsy.

The purpose of this study was to investigate implant-supported restoration as a technique for restoring missing teeth in patients with aplastic anemia. Recurrent bleeding from wound sites leads to persistent release of iron in the tissue. Excessive iron in tissue is related to clinical findings, including fibrosis, poor wound healing, and high level of angiogenesis, which are possible etiological factors of reduced osseointegration. A 44-year-old female patient with aplastic anemia was treated with multiple endosseous implants throughout the mandible and in the posterior region of the maxilla. After 14 implants were placed, radiological and clinical parameters were assessed during the follow-up period. Marginal bone did not change significantly during the follow-up period. The fine trabecular bone in intimate contact and enclosing the implant fixture was sufficient for successful osseointegration. None of the 14 implants were associated with compilations during the seven-year experimental period. This study suggests that dental implant procedures are a safe and reliable treatment option for restoration of missing dentition in patients with aplastic anemia.

Adenomatoid odontogenic tumor (AOT) is a rare benign odontogenic jaw lesion. It usually occurs in the anterior maxilla and is mostly related to impacted canines in teenagers. A 3-year-old girl was referred from a local dental clinic due to delayed eruption of the right primary mandibular 2nd molar. There was no history of pain or swelling. Radiography revealed a large radiolucency lesion with radiopacities around the unerupted right primary mandibular 2nd molar. Surgical enucleation with extraction of the right primary mandibular 2nd molar and surgical biopsy were performed. Based on the clinical and radiological findings, this lesion was defined as an ameloblastic fibro-odontoma which often develops in the mandible of adolescents. However, this lesion was diagnosed as AOT from the results of the histological examination. This report aimed to present a rare case of AOT in the posterior mandibular area in a very young patient.

Acute eosinophilic pneumonia (AEP) has been described as an idiopathic febrile illness with a duration of less than seven days with severe hypoxemia, pulmonary infiltrates, and no history of asthma. It has been reported that AEP is associated with smoking. Although the pathogenesis of smoking induced AEP is being actively studied, there is no direct histological evidence that smoking actually induces AEP. Recently, we encountered a case of AEP that may have been caused by smoking. We performed a cigarette smoking challenge test to verify that smoking was indeed the cause of AEP in this patient. Smoking induced an increase the proportion of eosinophils in the bronchoalveolar lavage fluid without any respiratory symptoms or abnormal radiological findings. This result suggests that smoking was the cause of AEP in this patient.
