It has been emphasized that treatment of hemoral neck fracture is early anatomical reduction and rigid internal fixation to reduce severe complications such as avascular necrosis or non-union.Operative treatment were developed recently with development of radiological technique. This study reviewed twenty-nine patients of femoral neck fracture treated by internal fixation between December 1973 and December 1979. There are eleven casesof Garden's stage I or II fracture with multiple Knowles pinning and eighteen cases (All Gardens stage) treated with compression hip screw, and followed for a minimum of nine months with an average eighteen months. The results were as follows; 1. Eleven cases with minimal displaced fracture (Garden's stage I or II) treated by multiple Knowles pinning were revealed good results. 2. In total eighteen cases treated by compression hip screw, nine cases (Garden's stage I or II) were revealed good results and other nine cases (Garden's stage I or II) were revealed fair or poor results. 3. Eleven cases of mlutiple Knowles pinning and nine case of compressian hip screw used for undisplaced fracture (Garden's stage I or II) were revealed good results without regard to internal fixation devices. 4. Avascular necrosis were four cases in nine cases(44%) of displaced fracture. 5. Non-union were not found in this aeries.

The utility of computerized tomogaphy in the study of the anatomy, and pathology of the musculoskeletal system has been the subject of considerable interest since the introduction of CT scanning. It provides an accurate and detailed cross-sectional image of normal anatomical structures and shows the relation of masses to these structures. In order to assess the utility of computed tomography, we analyzed the 92 clinical cases. We divided our experience into three major categories: spinal lesios, pelvic (including hip) lesions, and lesions of extremities. The advent of a new prototype scanning device has made it possible to exam a variety of abonormalities in the orthopedic diseases in a manner not previously possible.

A case of child fasciola liver abscess was reported. This case was a. A 5-years-old boy who had a history of fever and abdominal pain for 2 days. There was eosinophilia (15%) and an abdominal ultrasound demonstrated heterogenous hypoechoic mass in the liver. He was diagnosed with bacterial liver abscess and was treated with Unasyn, Amikin, Cefotaxime, and metronidazole. But, the fever did not subside completely and blood eosinophil count was increased to 50%. New hypoechoic lesion in the liver was revealed on the follow-up abdominal ultrasound. Liver biopsy was done and it revealed eosinophil infiltration. Also, there was eosinophil infiltration (20%) in his bone marrow. The serologic test for parasite-specific IgG antibody by micro-ELISA confirmed the diagnosis of Fasciola hepatica infection. He was successfully treated for two days with oral Triclabendazole, 15 mg/kg, daily. Blood eosinophil count was down to 10% and there was no abnormal lesion in the liver on abdominal ultrasound finding.

PURPOSE: Foreign body aspiration in the tracheobronchial tree is a common medical emergency in children and represents an important cause of morbidity and mortality. This study was aimed to analyze the clinical spectrum of tracheobronchial foreign bodies in children and to evaluate the causes of late diagnoses. METHODS: A total of 108 patients with foreign body aspiration were recruited in the last 10 years, who had a flexible or rigid bronchoscopic examination. The age, sex, symptoms, causes of aspiration, radiologic findings, and clinical courses were investigated retrospectively. Patients were divided into 2 groups according to the elapsed time from aspiration to a definite diagnosis as early (< or =24 hours after aspiration) and late diagnoses (>24 hours after aspiration). The two groups were compared for clinical courses, radiologic findings, and the duration of admission of early- and late-diagnosed foreign body aspiration. RESULTS: Approximately 80% of the patients were less than 24 months of age and the most common symptoms were the sudden onset of a cough. Hyperinflation or obstructive emphysema (52.8%) and normal chest radiographs (19.4%) were the most frequent radiologic findings. Plain chest radiographies revealed visible foreign bodies in 7.4% of all patients with foreign body aspiration. Nuts were the most common foreign bodies aspirated. Sudden onset of a persistent cough and fever were predominant in the late-diagnosed group.(P<0.05) CONCLUSION: Our results suggest that clinical suspicion upon interviewing is enough to indicate bronchoscopy. The best way to reduce the number of accidents and deaths associated with foreign body aspiration is to promote public prevention polices.

BACKGROUND: Electromagnetic fields (EMF) are ubiquitous in modern society including medical field. As the technology of medical instruments and telecommunications has developed rapidly, it has influenced on our lives in many ways. Modern medical practice requires high quality medical equipments, which have a great deal of electromagnetic interference and susceptibility. The purpose of this study were to evaluate electromagnetic condition under usual clinical condition and to suggest a practical guideline in general hospital. MATERIALS AND METHODS: The actual state of the electromagnetic interference in the medical field was studied under usual clinical conditions including operating rooms, intensive care units, magnetic resonance imaging unit, and hyperthermia unit. RESULTS: There was considerable noise as a result of electromagnetic fields from medical equipments including electrosurgical units and hyperthermia unit, and cellular phones, which could induce serious functional derangements of functioning medical devices. CONCLUSION: It will be necessary to evaluate the individual electromagnetic situations under various medical conditions and to define a limited zone for cellular phone as well as reposition medical equipments to secure a safer medical practice and to minimize electromagnetic interference.

PURPOSE: Peanut allergy is a major cause of fatal food-induced anaphylaxis. Cooking methods can affect the allergic properties of peanut proteins. The aim of this study was to determine the allergenicity of peanut according to cooking methods. METHODS: Eight kinds of peanut were included in the study: raw peanut, boiled peanut, roasted peanut (10 min, 20 min and 30 min), peanut butter, fried peanut and vinegarish peanut. The proteins were extracted with PBS and analyzed using the SDS-PAGE IgE immunoblot assay with pooled sera from 8 patients with atopic dermatitis. These patients had peanut- specific IgE levels greater than 15 kU/L, which were measured by the CAP-FEIA. RESULTS: The SDS-PAGE IgE immunoblot assay revealed more intense protein bands of Ara h 2 in roasted peanut and peanut butter than in raw, boiled, fried and vinegarish peanut. The protein band of Ara h 1 was not undetected in fried and vinegarish peanut. Ara h 3 had a stable band pattern in all samples, but there was the most prominent band at 37-40 kDa in vinegarish peanut. The IgE immunoblot assay revealed that 10 min roasted peanut had more IgE binding to Ara h 2, and there was no IgE binding to Ara h 1 in fried and vinegarish peanut. In vinegarish peanut, there was almost no IgE binding to it. CONCLUSION: The results of this study suggest that the roasted peanut may increase the allergenicity of Ara h 2 as compared to Ara h 1. Fried and vinegarish peanut may reduce the allergenicity of peanut.

OBJECTIVE: The changes of magnetic resonance signal intensity after the local steroid injection in to the muscle and tendon in mongrel dogs and the subacromial spaces of patients were studied. MATERIALS AND METHODS: Local injection of the methylprednosolone acetate was performed in muscles and tendons of the limbs of ten mongrel dogs and rotator cuffs of patients. Normal saline was injected in to six muscles and tendons as a control. MR imaging was obtained before and after the local injection of methylprednisolone and the normal saline. RESULTS: After one week and two weeks after the injection, increased signal intensity on T2-weighted fast spin echo MR image was found in four and five of ten muscles and tendons respectively, to which methylpredisolone was injected. None of the muscles or tendons, to which normal saline was injected, showed increased signal intensity on follow-up MR imaging. The cases with increased signal intensity were interpreted as having a inflammation or injury. Moreover, in the clinical study, two of five patients who underwent local steroid injection showed an area of increased signal intensity on T2-weighted fast spin echo MR imaging. CONCLUSION: MR images after local steroid injection should be interpreted carefully with regard to the previous steroid injection.

PURPOSE: To evaluate the postoperative MR findings of the healthy anterior cruciate ligament (ACL) grafts which were confirmed by the second-look arthroscopic examination. MATERIALS AND METHODS: Among 419 cases who underwent the arthroscopic ACL reconstruction by one operator between June 1996 and January 2001, we evaluated 33 MR scans of 29 patients who underwent the postoperative MR scan and the second-look arthroscopic examination (4 patients underwent postoperative MRI twice). There were 18 male and 11 female patients, and the patient 's age ranges from 16 to 59 years-old (mean 29.7). There were 15 cases of autogeneous bone-patellar tendon-bone (BPTB) grafts, 13 cases of autogeneous double-loop hamstring grafts, and 1 case of allogeneous BPTB graft. Thirty-three MRIs were divided into 3 groups according to the time interval between operation and postoperative MR examination: less than 6 months, 7 to 12 months, and more than 13 months. The MR findings of ACL grafts - signal intensity, morphology, continuity, orientation, diameter - were analyzed. RESULTS: The increased signal intensity was found in 29 ACL grafts (87.7%) among 33 MR images. The most common pattern of the graft morphology was a longitudinal streak increased signal band (27 cases, 81.8%). The partial rupture was seen in 9 cases (27.3%), and the lax orientation in 4 cases (12.1%). According to Howell 's scoring system, the signal intensity score of the graft tended to decrease with time after operation, and the sagittal diameter of the graft tended to increase with time after operation. CONCLUSION: The main MR finding of the healthy ACL graft was longitudinal streak increased signal band. The graft signal intensity seemed to decrease, and the sagittal diameter of the graft seemed to increase, as time passes after operation.
