PURPOSE: To report a case of subhyaloid hemorrhage which resulted from bungee jumping and to describe the clinical course. METHODS: A 21-year-old man who presented with acute diminution in vision following bungee jumping from a height of approximately 64m visited our ophthalmologic department 3 days after the jump. RESULTS: Best uncorrected visual acuity (UCVA) was right eye 1.0 and left eye F.C 10cm initially. He demonstrated a periocular contusion of about 1cm in the left lateral eyebrow. A full examination of the anterior segment was normal but his left fundus showed a subhyaloid hemorrhage of about 7 disc-diameters in size. There were surrounding superficial retinal hemorrhages and peripheral retinal edema. At 54 days follow-up, subhyaloid hemorrhage of about 5 disc-diameters in size remained and visual acuity was not improved. Trans pars plana vitrectomy was performed in his left eye and improved his vision. One month after the operation, the vision was 1.0 unaided in the left eye. The visual acuity remained as 1.0 eight months after the operation. CONCLUSIONS: It is important that the public should be educated about the potential hazard of bungee jumping and we recommend the use of safety glasses during the bungee jump.

Purpose: To evaluate the clinical and radiographic results of primary bipolar arthroplasty during average 9.8-year period, using a non-cemented Multilock femoral stem and a biarticular acetabular cup. Materials and Methods: This study included 24 patients (29 hips) who underwent primary bipolar hemiarthroplasties with Multilock femoral stems and biarticular cups and who could be followed for more than seven years. Clinically, we evaluated the Harris Hip scores and patient complaints of thigh and inguinal pain. We also evaluated the radiographic measurements around the femoral stems and the bipolar cups. Results: The average Harris Hip score improved from 57.4 points to 91.6 points; and 3 (10.3%) hips were associated with thigh pain and 4 (13.8%) hips with inguinal pain. Around the femoral stem there was a non-progressive radiolucent line less than 1 mm in length in 4 (13.8%) hips and osteolysis was present in 6 (20.6%) hips. With respect to the stability of the fixations, there was osseous ingrowth in 26 (89.7%) hips and fibrous ingrowth in 3 (10.3%) hips. Around the acetabulum there was osteolysis in 5 (17.2%) hips, proximal migration of the cup in 2 (6.9%) hips, and erosion of the acetabular cartilage in 10 (34.5%) hips. There were 3 (10.3%) biarticular cups, which were converted to total hip arthroplasties, but no femoral stems were revised. The overall failure rate of the primary operations was 10.3%. Conclusion: The current study demonstrated favorable results after bipolar hemiarthroplasties with Multilock femoral stems. However, the osteolysis that occurred around the femoral stems and the acetabula emerged as a problem after the total hip arthroplasties. In particular, it is expected that the osteolysis would increase over time and become the main cause for the need for surgical revision.

BACKGROUND/AIMS: Radiopaque metal markers are required to improve X-ray absorption by self-expandable metal stents (SEMSs) to enable precise stent placement. A new tantalum radiopaque marker was recently developed using an ultrasonic spray technique. The aim of the present study was to evaluate the safety and visibility of tantalum markers. METHODS: A total of three beagle dogs were used for a gastrointestinal tract absorption test. Five tantalum markers were placed in the stomach of each dog endoscopically. Excreted tantalum markers were collected, and their weights were compared to the original weights. In radiopacity tests, marker radiopacities on X-ray images were quantified using ImageJ software and compared with those of commercially available metal markers. Finally, the radiographic images of six patients who underwent biliary SEMS placement using tantalum marker Nitinol SEMSs (n=3) or gold marker Nitinol SEMSs (n=3) were compared with respect to marker brightness on fluoroscopic images. RESULTS: Absorption testing showed that the marker structures and weights were unaffected. Radiopacity tests showed that the mean brightness and total brightness scores were greater for tantalum markers (226.22 and 757, respectively) than for gold (A, 209 and 355, respectively; B, 204.96 and 394, respectively; C, 194.34 and 281, respectively) or platinum markers (D, 203.6 and 98, respectively). On fluoroscopic images, tantalum markers had higher brightness and total brightness scores (41.47 and 497.67, respectively) in human bile ducts than gold markers (28.37 and 227, respectively). CONCLUSIONS: Tantalum markers were found to be more visible than other commercially available markers in X-ray images and to be resistant to gastrointestinal absorption.

PURPOSE: To identify the characteristic ultrasonographic findings of the normal appendix in children in order to detect it more easily and so to exclude acute appendicitis from a diagnosis with more confidence. MATERIALS AND METHODS: Among 64 patients presenting with right lower quadrant pain, 44 patients, excluding 15 patients diagnosed as acute appendicitis and 5 patients with non-visualization of the appendix due to severe ileus and obesity, were evaluated for the point of incidence, the thickness and the presence of folding of the inner hypoechoic band of the normal appendix. The age of the patients ranged from 3 to 15 years with a mean age of 6.5 years. Two patients were operated on and we correlated the preoperative ultrasonographic findings with the histologic findings. RESULTS: In all the cases of the 44 patients with normal appendix, the inner hypoechoic band was discovered, which was seen as a linear structure without folding along the whole length of appendix. This measured as 0.75 mm (0.3-1.5 mm) for the mean thickness. The inner hypoechoic band corresponded to the mucosal layer that had abundant lymphoid tissue on the histologic examination. CONCLUSION:For the pediatric normal appendix, the inner hypoechoic band without folding is present, and this corresponds to the mucosal layer with abundant lymphoid tissue.

PURPOSE: We analyzed the association of lymph node ratio (LNR) wth locoregional control (LRC) in breast cancer patients with ≥10 involved axillary lymph nodes who underwent multimodality treatment. METHODS: We retrospectively analyzed 234 breast cancer patients with ≥10 involved axillary lymph nodes between 2000 and 2011. All patients received adjuvant chemotherapy and radiotherapy (RT) after radical surgery. The cutoff value of LNR was obtained using receiver operating characteristic curve analysis. The majority of patients (87.2%) received chemotherapeutic regimen including taxane. RT consisted of tangential fields to the chest wall or intact breast, delivered at a median dose of 50 Gy, and a single anterior port to the supraclavicular lymph node area, delivered at a median dose of 50 Gy. For patients who underwent breast-conserving surgery, an electron boost with a total dose of 9 to 15 Gy was delivered to the tumor bed. RESULTS: Within a median follow-up period of 73.5 months (range, 11-183 months), locoregional recurrence (LRR) occurred in 30 patients (12.8%) and the 5-year LRC rate was 88.8%. After multivariate analysis, LNR ≥0.7 was the only independent factor significantly associated with LRC (hazard ratio, 2.06; 95% confidence interval, 0.99-4.29; p=0.05). CONCLUSION: An aggressive multimodal treatment approach showed favorable locoregional outcome in patients with ≥10 involved axillary lymph nodes. However, patients with a high LNR ≥0.7 still had an increased risk for LRR, even in the setting of current local treatments.

Lateral pharyngeal space is one of potential fascial planes of head and neck, that may become involved by various pathological processes, such as infection, inflammation and neoplasm. The calcified stylohyoid ligament with styloid process is also located in this space, so this space is more acquainted with Eagle's syndrome in oral and maxillofacial field. During the mandibular transbuccal fixation procedures of 29-year old female patient who had right condylar neck and left parasymphysis fracture, we had lost one 10.0 mm miniscrew. After confirming the location of the lost miniscrew from different angled plain skull radiographies, we tried to find it in the lateral pharyngeal space via transtonsillar approach at the time of plate removal operation. This case report is aimed to share our valuable experience of the effective approach way to the lateral pharyngeal space, which has many advantages, such as short operative time, minimal bleeding, fast post-operative recovery, and less morbidity. The related literature is also reviewed.

OBJECTIVE: To investigate the prevalence of vitamin D inadequacy in an elderly patients with hip fracture. METHODS: A prospective study was carried out for 2 years (January 2008 - December 2009). Patient records were searched for hip fracture admission and cross matched with serum vitamin D levels and bone densitometry carried out within 3 days of the hip fracture admission. RESULTS: There were data for 115 hip fracture patient, 69% of the patients were women (n = 79). The mean age at the time of fracture was 76.1 years. The mean of bone densitometry was -2.8 +/- 0.8. About 40% of the patients had a bone mineral density (BMD) below -3.0. The mean vitamin D (25-OH) level was 20.9 +/- 10 ng/mL. Over 80% of patients had a vitamin D level below 30 ng/mL. Especially, patients (n = 17) admitted from assisted nursing home had less a vitamin D level (16.3 ng/mL) than patients admitted from home (22.9 ng/mL). There were no significant differences by age or sex however, there was seasonal differences in vitamin D. CONCLUSION: This study reveals universal vitamin D inadequacy in hip fracture patients.
