PURPOSE: The aim of this study was to assess the mid-term results of primary cementless total hip arthroplasty (THA) using Summit® stems. MATERIALS AND METHODS: One hundred twenty-eight arthroplasties in 121 patients who were performed THA from December 2004 to March 2013, were reviewed retrospectively a minimum of 4 years follow-up (mean age, 60.3 years; mean postoperative follow up period, 86.3 months). For a clinical evaluation, the Harris hip score (HHS) was used to assess outcome. Radiographic evaluation was done through spot welds, subsidence, stress shielding, canal filling. RESULTS: The mean HHS was 69.8 points preoperatively, and it improved significantly to 96.3 points at the final follow-up. Postoperatively, 10 patients experienced thigh pain and 7 patients showed a moderate limping gait. There was not only early stem subsidence but there was no more subsidence at last follow up. One hundred eighteen hips showed radiographic signs of stem bone ingrowth, and 10 hips showed fibrous ingrowth at the last follow-up. Stress shielding occurred in 85 hips and third degree stress shielding was observed in 6 hips. Complication arose in 10 hips due to dislocation. Although revisions due to recurrent dislocations led to acetabular component revision in one hip, no revisions arose due to isolated aseptic loosening of the femoral component. CONCLUSION: The clinical and radiological mid-term results of primary THA using Summit® stems revealed solid initial fixation and bone ingrowth stable fixation. Considering the satisfactory clinical results, Summit® stems may be a good treatment option in Korean patients who were required hip arthroplasty

PURPOSE: To compare the usefulness of double-dose contrast-enhanced CT (DDCE-CT) and conventional contrast-enhanced CT (CCE-CT) in the detection of metastatic brain lesions. MATERIALS AND METHODS: Sixteen patients with brain metastases were evaluated with both CCE-CT and thinslice DDCE-CT. For CCE-CT, an initial injection of 100 ml contrast medium was given, and DDCE-CT with both 10-mm and 5-mm thickness was performed after the addition of an extra 100 ml of contrast medium. The numbers of metastatic lesions detected by CCE-CT and by DDCE-CT were compared, as were the findings of contrast-enhanced MRI (CE-MRI) and thin-slice DDCE-CT in seven patients who underwent both these procedures. RESULTS: Fourteen metastatic brain lesions were detected by CCE-CT, 22 by 10-mm-thickness DDCE-CT, and 36 by 5-mm thickness DDCE-CT. Thus, almost 2.6 times more lesions were detected by thin-slice DDCE-CT than by CCE-CT. Metastatic lesions were detected by 10-mm-thickness DDCE-CT in 16 patients and by CCECT in seven; in five, edema only was detected, while in four there were no detectable metastases. CCE-CT detected four lesions of less than 5 mm in diameter, while 10-mm-thickness DDCE-CT and 5-mm-thickness DDCE-CT detected seven and 18 lesions, respectively. Eleven lesions were detected by thin-slice DDCE-CT and 17 by CE-MRI in the seven patients who underwent both CE-MRI and DDCE-CT. The lesions detected only by CE-MRI were less than 5 mm in diameter and were discovered in the cerebellum or inferior temporal lobe. CONCLUSION: Thin-slice DDCE-CT was superior to CCE-CT in detecting metastatic brain lesions.

BACKGROUND: Nowadays, as public awareness of t,he Acquired immunedeficiency syndrome(AIDS) epidemic was increasing, athletes have become more concerned about their risk of infection with human immunedeficiency virus(HIV) since it, was announced that Magic Johnson, hero of basketball in the United States, was infected. Because there are no exact cure method about AIDS, the only treatment is prevention through the education and awareness of AIDS. Therefore, we researched the athletes knowledge of AIDS to provide the b#asis of preventive methods. METHODS: A questionnaire was given directly to the 110 wrestling and taekwondo athletes attending a sports college. RESULT: Athletes are all men and their mean age is 24.6 years old. Concerning the question of latent period, 54.5% had correct answer that AIDS development took more than several years after HIV infection. The person who had educated about the preventive methods of infection during the sports was 4.6%. The person who answered AIDS athletes should be excluded from the sports was 64.5% and the reason of exclusion was the risk of infection through the small bleeding(49.8%), sweating(38.0%), and simple skin cont,acts(19. 7%) during the sports. The correct recognition rate of preventive method of infection during the sports was 51.8 to 62%. Concerning the risk routes and behaviors of infection during daily life, most of them recognized correctly(from 76,3% to 99.0% by each item), but some have also misconception about transfusion(61.0%), skin contact(33%) and mosquitos bite(30%) etc. CONCLUSION: Almost all of athletes recognized correctly the risky behavior of sex and blood in transmission of infection, but some have also misconception in daily activities, e.g. transfusion and mosquitos. Many persons answered AIDS infected athletes should be excluded from the sports and they didnt receive any education about preventive methods of AIDS infection during the sports. The knowledge of preventive methods of infection recommended during the sports was relatively high.

Spinal paragonimiasis is an uncommon ectopic manifestation of the lung fluke. In this paper eight cases of spinal paragonimiasis treated in the Severance Hospital are reported and the literature is reviewed. Differantial diagnosis is usually difficult because of the similarity of symptoms and signs with benign spinal cord tumors. positive chest X-ray findings, positive skin test and pleocytosis of the spinal fluid, especially of eosinsphils, are valuable findings in the diagnosis. The extradural space in the 1ower thoracic region is the most frequently affected area. Laminectomy with excision of the lesion supported by chemotherapy is the treatment of choice. When treated early, prognosis of this type of manfestation is usually favorable.

CT and MR findings of nine cases with intratemporal facial nerve nouromas were described and compared with CT findings of 3 cases with facial nerve palsy and facial nerve canal erosion which may mimic facial nerve neuroma. The tympanic segment of the facial nerve was involved in 8 cases, mastoid segment in 7 cases and labyrinthine segment in 5 cases. The lesions were easily diagnosed with high resolution CT with bone algorythms by showing the expansion of bony structures along the course of the facial nerves. In 4 cases with large vertical segment tumors. Extensive destruction of mastoid air cells and external auditory canals posed difficulty in making a diagnosis. Two out of 5 cases with labyrinthine segment imvolvement were presented as middle cranial fossa masses. MRI with enhancement was performed in 4 cases and was useful in characterizing the lesion as a tumor with its superior sensitivity to enhancement. Three cases of facial neuroma-mimicking lesion including post-inflammatory perineural thickening. Perineural extension from parotid adenoidcystic carcinoma, and congenita: cholesteatoma showed irrgular erosion or mild expansion of the facial nerve canal which may be helpful for differential diagnosis from neuromas.
