In general. femoral neck fracture in young adult presents poor prognosis due to the high velocity injury, high angle shear fracture, and poor candidate for arthroplasty. In addition to the relative rarity of the injury, the high incidence of aseptic necrosis and nonunion have been reported in the management of these fractures. 25 cases of femoral neck fracture in young adult were treated with multiple pinning and analyzed at Sung-Ae general hospital from 1987 to 1994 after 28 months follow up in average with review of charts, X-ray and clinical result. There were 18 male and 7 female, 5 cases of them had significant polytrauma to other organs or skeletal system, authors tried to treat them as soon as possible to decrease the interval time between fracture and fixation (the average time was 39.7 hours.) Union occurred in all of Garden stage I (4 cases) and II (4 cases), but in Garden stage III (7 among 8 cases) and IV (7 among 9 cases) the union rate was lower. Average union time was 16.5 weeks. The incidence of complications (12%, 3 among 25 cases) was higher in displaced fractures group (Garden stage III, IV) and also in poorly reduced group of Garden’s alignment index. In conclusion, the prognosis of femoral neck fractures in young adult was related with mainly initial reduction and rigid fixation than the initial injury.

OBJECTIVE: This study was conducted to measure radiographic joint space width and to estimate erosion in the hands of patients with rheumatoid arthritis. It showed that joint space width, homogeneity, and invariant moments are parameters to discriminate between the normal and the rheumatoid joint. METHODS: In order to measure the joint space width and to estimate erosion in the finger joint, 32 radiographic images were used - 16 images for training and 16 images for testing. The joint space width was measured in order to quantify the joint space narrowing. Also, homogeneity and invariant moments was computed in order to quantify erosion. Finally, artificial neural networks were constructed and tested as a classifier distinguishing between the normal and the rheumatoid joint. RESULTS: The joint space width of normal was 1.04+/-0.15 mm and the width of patients with rheumatoid arthritis was 0.94+/-0.15 mm. The Homogeneity of normal was 16568.83+/-2669.83 and invariant moments were 6843.45+/-2937.55. They were statistically difference (p<.05). Using these characteristics, artificial neural networks showed that they discriminate between normal and rheumatoid arthritis (AUC=0.91). CONCLUSION: Measuring joint space width, estimating homogeneity, and invariant moments provide the capability to distinguish between a normal joint and a rheumatoid joint.

PURPOSE: To evaluate the differential features of complete and partial-thickness tears of the anteriorcruciate ligament, as seen on magnetic resonance imaging(MRI). MATERIALS AND METHODS: We retrospectvely reviewedMR images of 36 patients with ACL injuries (complete tear 16, incomplete tear 20). In all cases, the presence ofan ACL tear was determined by arthroscopy or surgery. Primary and secondary signs of ACL injury and associatedinjuries were assessed. RESULTS: Ligamentous discontinuity of the ACL was observed in ten complete tears (63 %),but in only four (10%) of those that were partial (p=0.009). In addition, complete tears were more likely to showa low degree of ACL axis, less than 45 degree(11/16 : 2/20, p=0.001). There was, however, no statistically significantdifference between complete and partial tears with regard to signal intensity of ACL, PCL buckling or angle,anterior dis-placement of the tibia, uncovered meniscus sign, deep notch sign, empty notch sign, and associatedinjuries. CONCLUSION: Ligamentous discontinuity and the ACL axis are features which usefully differentiatebetween complete and partial tears of the ACL.

Bezoars are collection of indigestible materials in the gastrointestinal tract. Many endoscopic techniques for removal of bezoars have been reported recently, but these methods need much equipment. We treated a gastric bezoar with a distal attachment device easily available for an endoscope. A 74-year-old man with a history of diabetes mellitus was admitted to hospital with hematemesis. On the second endoscopic examination, a gastric bezoar (6x4x4 cm) was detected in the stomach. Then, using a distal attachment device, we injected Coca-Cola directly into the bezoar by an injector. With tension force, the bezoar was easily broken due to the impulse of the distal attachment device. The endoscopic technique used in our case can be easily performed and has fewer complications compared to those of other techniques. Therefore, we report here on this new treatment modality that uses a distal attachment device.

Right internal jugular vein is preferred for central venous catheter insertion because of fewer complications. However, insertion-related complications can occur such as arterial puncture, pneumothorax, and hemothorax. Arrhythmia can also occur, but it has been reported to temporarily occur only during guidewire insertion. We report a case of symptomatic paroxysmal atrial fibrillation induced by right internal jugular venous catheterization for hemodialysis. The chest X-ray taken after insertion of the catheter showed that the catheter was advanced too deeply into right atrium from an unusually lower puncture site. The atrial fibrillation persisted nearly 24 hours and was corrected by removal of the catheter. We experienced that paroxysmal atrial fibrillation can be complicated by central venous catheterization, and appropriate selection of puncture site and catheter length is important to avoid it.

Zenker diverticulum is a rare condition with a reported prevalence of 0.01% to 0.11% in the general population. Challenges that can arise when treating a Zenker diverticulum through flexible endoscopy include maintaining a stable position and avoiding hemorrhage or perforation. Nevertheless, this approach is associated with less morbidity and a shorter hospital stay than conventional treatment consisting of open surgery or rigid endoscopic treatment with diverticuloscopy. We report a case of transparent cap-assisted flexible endoscopic septoplasty using a needle knife.

PURPOSE: To assess the incidence of neonatal hearing loss in a neonatal intensive care unit and the relative importance of risk factors for hearing imparement in a neonatal intensive care unit which the Joint Committee on Infant Hearing(JCIH) had recommended. METHODS: One thousand, two hundred and one newborns admitted to the Good Moonhwa Intensive Care Unit from May 2003 to December 2005 were assesed using the automated auditory brainstem response(AABR). The screening was performed on those aged more than 36 weeks and weighing more than 2,200 g. We divided the infants into two groups, 'pass' and 'refer'. The 'refer' group were retested one month later, and if classified as 'refer' during the retest, were referred to a hearing impairment clinic. RESULTS: From the 1,201 neonates, 1,187(98.8 percent) passed the test and 14(1.2 percent) failed. 293(24.4 percent) of the 1,201 neonates had a risk factor for hearing impairment; 282(96.2 percent) passed the test and 11(3.8 percent) failed. The group with risk factors were shown to have a higher incidence of hearing loss(P<0.001). The neonates in the refer group were shown to have a higher incidence of ototoxic drugs(P<0.001), low birth weight(<1,500 g)(P<0.001) and craniofacial anomalies(P=0.007). On the other hand, there were no statistical differences between the pass and refer groups in congenital infection, hyperbilirubinemia, bacterial meningitis, low Apgar scores, prolonged mechanical ventilation and syndromes known to include hearing loss. CONCLUSION: In order to identify hearing-impaired infants within an appropriate period, neonatal hearing screening tests and identification of the risk factors for neonatal hearing loss are important.
