BACKGROUND: The goal of this study was to evaluate whether a modified fluoroscopic technique for positioning a hook plate affected the clinical results of treating Neer type II distal clavicle fractures and Rockwood type V acromioclavicular (AC) joint separations with this device. METHODS: The study was a retrospective consecutive case series with data analysis. Sixty-four patients with a Neer type II distal clavicle fracture or a Rockwood type V AC joint injury treated between March 2009 and June 2013 were divided into 2 groups: traditional fluoroscopic technique (traditional view, 31 patients) or modified fluoroscopic technique ('hook' view, 33 patients). A visual analogue scale (VAS) score, the modified University of California-Los Angeles (UCLA) shoulder scale score, and radiographic osteolysis were the main outcome measures. RESULTS: The traditional group included a significantly larger number of patients with acromial osteolysis than the hook view group: 23 patients (74.2%) vs. 11 patients (33.3%), respectively (p=0.01). Before plate removal, the hook group reported less pain and higher UCLA shoulder scale scores than the traditional group: average VAS score, 1.55 vs. 2.26, respectively; average UCLA score, 30.88 vs. 27.06, respectively. However, there was no significant difference after plate removal. CONCLUSIONS: The hook view allows more accurate bending of the hook plate around the contour of the acromion, resulting in decreased osteolysis, decreased pain, and better function with the plate in situ.

PURPOSE: The purpose of this study was to evaluate the clinical results of fixation of the unstable osteochondral dissecans (OCD) lesion with autologous osteochondral plugs. MATERIALS AND METHODS: This study was conducted in 19 patients who were relevant to the International Cartilage Repair Society 2, 3, or 4 who were treated with autologous osteochondral plugs and followed-up for more than 2 years from January 2004 to January 2012. Clinical evaluation was performed by comparing the preoperative and last follow-up scores of Lysholm score and subjective International Knee Documentation Committee (IKDC) score. RESULTS: All patients were male and the average age was 19.1 years. Of the 19 cases, there were 16 cases of medial femoral condyle lateral side lesion, 2 cases of lateral femoral condyle articular surface, and 1 case of femoral intercondylar notch lesions. The average size of the lesion was 5.68 mm2, and average use of osteochodral plugs were 4.3. Average follow-up period was 38 months. Preoperative Lysholm score, IKDC subjective score showed significant improvement. CONCLUSION: Fixation with autologous osteochondral plugs for unstable OCD uses the remnant tissues therefore conserving it, which is thought to be the positive aspect of this type of operation.

PURPOSE: The purpose of this study was to retrospectively analyze the etiologic transition of the predisposing factors and organisms for septic arthritis of the knee. MATERIALS AND METHODS: Between January 1995 and December 2006, 122 cases of septic arthritis of the knee were retrospectively evaluated for the etiologic transition and causative organism with using the patients' medical records. We researched the incidence and causative factor of septic arthritis of the knee, which was diagnosed via the patients' symptoms, physical examinations, hematologic exams, culture studies & cytology of the joint fluid. We assessed the correlation of disease with age, the year the disease happened, the causative factors and the incidence. RESULTS: Septic arthritis of the knee was increased after 40 years old, and it also increased after 1998. The most common predisposing factor was intra-articular injection of the knee joint. Even though there were no detected organisms in 79 cases (64.8%), the most common causative organism was S. aureus (20.5%). CONCLUSION: The most common etiologic factor of septic arthritis of the knee was an intra-articular injection. We should be prudent for using good aseptic technique and the correct procedure to reduce the secondary infection that's recently due to increased invasive treatment of the knee joint.

In order to help define the possible role of adhesion molecules in corneal inflammation, we investigated the distribution of adhesion molecules in normal and Aspergillus fumigatus keratitis-induced corneas of rabbits in process if time. Each 4 corneas were resected at 3, 12, 24, and 72 hours after intracorneal injection with A. fumigatus. Normal corneas (4 eyes) were used as a control. Monoclonal antibodies to beta 1 subunit of VLAs, alpha 1 subunit of VLA-1, LFA-1, ICAM-1,and ELAM-1 were used for immunohistochemical staining of 20 corneas.The results were as follows: In normal cornea, beta 1 subunit of VLAs was expressed on all parts of the cornea, and ICAM-1 was expressed on corneal stroma and endothelium. Vascular endothelium showed expression of beta 1 subunit of VLAs and ICAM-1 after 12 hours of intracorneal injection, and alpha1 subunit of VLA-1 and ELAM-1 at 72 hours after injection. In inflamed cornea, beta 1 subunit of VLAs was expressed strongly at 72 hours after injection. Alpha1 subunit of VLA-1 was detected on corneal stroma after 12 hours of injection, and on corneal endothelium at 72hours after injection. Expression of beta 2 subunit of LFA-1 was weak on corneal stroma after 3 hours injection, and on corneal endothelium at 72 hours after injection. ICAM-1 expression was detected weakly on corneal epithelium, and increased on corneal stroma and endothelium at 72 hours after injection. ELAM-1 was expressed weakly on corneal stroma after 3 hours of injection, and on corneal endothelium at 72 hours after injection.In this study, it was found that the invasion of A. fumigatusinto the cornea causes localized inflammatory reaction that results in activation of corneal cells (keratocytes, corneal endothelial cells and epithelial cells), and subsequent expression of adhesion molecules in the cornea. Expression of adhesion molecules facilitates the inflammatory cells to be migrated into the cornea with inflammmation.

Forty year old woman with dysphagia underwent surgical correction of complete vascular ring formed by right aortic arch, Kommerell's diverticulum and ligamentum arteriosum. Operation consisted of ligamentum division, reduction diverticuloplasty and posterior diverticulopexy via left posterolateral thoracotomy. Dysphagia was relieved postoperatively, and concentic narrowing of esophagus in the level of aortic arch disappeared on postoperative esophagography.

PURPOSE: This study was performed to analyze the position, pattern of impacted mesiodens, and their relationship to the adjacent teeth using Dental cone-beam CT. MATERIALS AND METHODS: Sixty-two dental cone-beam CT images with 81 impacted mesiodenses were selected from about 2,298 cone-beam CT images at Chonnam National University Dental Hospital from June 2006 to March 2009. The position, pattern, shape of impacted mesiodenses and their complications were analyzed in cone-beam CT including 3D images. RESULTS: The sex ratio (M : F) was 2.9 : 1. Most of the mesiodenses (87.7%) were located at palatal side to the incisors. 79% of the mesiodenses were conical in shape. 60.5% of the mesiodenses were inverted, 21% normal erupting direction, and 18.5% transverse direction. The complications due to the presence of mesiodenses were none in 43.5%, diastema in 19.4%, tooth displacement in 17.7%, delayed eruption or impaction in 12.9%, tooth rotation in 4.8%, and dentigerous cyst in 1.7%. CONCLUSION: Dental cone-beam CT images with 3D provided 3-dimensional perception of mesiodens to the neighboring teeth. This results would be helpful for management of the impacted mesiodens.

Coffin-Lowry syndrome (CLS) is a rare X-linked hereditary disorder characterized by moderate to severe mental retardation, facial dysmorphism, tapering fingers, and skeletal deformity. A 12-month-old boy was referred to our pediatric clinic for his developmental delay and seizure with fever. The boy exhibited a coarse facial appearance characterized by prominent, high-arched eyebrow, broad nose, downward palpebral fissure, high arched palate, hypodontia. The boy also showed finger tapering and puffy hand. Hypotonia, hyperextensible fingers and hypermobility of the joint were seen. Based on these findings, he was diagnosed as having Coffin-Lowry syndrome. We report a case of Coffin-Lowry syndrome with reference.
