There are few reports in the literature on how to care and manage bi!ateral congenital dislocation of the hip. Six patients have been encountered at this hospital from June 1979, of them four children had operative treat ment and the other two conservative. As a result of our experience about the management of bilateral congenital dislocation of the hip. The authors obtained the following conceptions; 1. The patient with bilateral dislocation was rather delayed in diagnosis. Therefore, in comp the treatment of bilateral cases was poorer than that of unilateral case. 2. In the case of the dislocated hip that might be easily reduced and maintained in the stab servative care was usually recommeded even in the older child. Unstable, unreduced hip,; hip in old children, the more definitive operation and internal & external rigid immobilization mandatory to get good result. 3. It might be beneficial to operate the more deformed and resistive hip first, and then to p with the same procedure 2 weeks after the first operation.

Avascular osteonecrosis has frequently occured in patients who have undergone transplantation of a kidney and generally has been considered to be a complication of the use of corticosteroids. But there are controversies regarding their dosage and duration of use in its influence on prevalence of avascular osteonecrosis. We analyzed the cases of our patients who underwent transplantation of a kidney and who we were able to follow up more than 8 months. l. Of a total of 300 patients, osteonecrosis developed in 24 joints of 12 patients. 2. Osteonecrosis was more frequently found in group of patients who were administered with larger doses of steroid. 3. Rejections of the transplanted kidney occured more frequently in those groups with osteonecrosis. 4. Most of rejections occured within 3 months after renal transplantation. 5. It took 4–26 months (average 12.3 months) the osteonecrosis could be found. 6. There were no differences in blood concentration of calcium phosphate and creatinine between osteonecrosis and non-osteonecrosis group. 7. Replacement arthroplasties were done in 10 joints without significant complication.

From September 1992 to April 1994, we reviewed 7 patients after arthroscopic surgery for anterior impingement in the ankle, who complained ankle pain and limitation of motion. All patients were mem and main symptoms were severe pain at full dorsiflexion of ankle and limitation of motion. Bony spur was located on the anterior aspect of tibia, and it was possible to resect the tibial bony spur arthroscopically without distraction devices. Mean operation time was 55 minutes. Pain, swelling and limitation of motion were much improved. There was no postoperative complication. Arthroscopic resection of the anterior tibial bony spur is an effective treatment for anterior impingement in the ankle.

OBJECTIVES: This study evaluated the availability of mandibular symphysis corticocancellous block grafts in patients treated for reconstruction of intraoral jaw defects. MATERIALS AND METHODS: 8 patients with mandibular and maxillary bony defects were treated with corticocancellous block of symphysis. The types of defects included 4 pathologic jaw defects and 4 vertical and/or horizontal alveolar deficiencies. The age ranged from 13 to 45 years. Additional treatments such as plate fixation, alloplastic bony substitutes, and/or barrier membrane application were perfomred. They were evaluated for complications and healing of defects. Follow-up period ranged from 6 to 15 months. RESULTS: 2 patients experienced complications such as wound dehiscence and mild resorption of exposed bone. None of the patients needed secondary operation. Paresthesia of lip, chin, and teeth were recovered completely by 6 months postoperatively. Reconstructed wound showed favorable healing and bony consolidation. CONCLUSION: Corticocancellous block of mandibular symphysis can be used for the reconstruction of a variety of intraoral local jaw defects selectively. Advantages were easy fixation of graft, possibility of restoration of original alveolar contour, and decreased donor site morbidity.

As more individuals were coronavirus disease 2019 (COVID-19) vaccinated, unexpected side effects appeared. Herein, we present the case of a 30-year-old male patient with myopathy in both extremities after the second dose of the Pfizer-BioNTech (BNT162b2) COVID-19 vaccine. Symptoms, swelling and pain, started from the proximal upper and lower extremities and extended to the distal parts. Although he underwent massive hydration, the muscle enzyme level continuously increased. He complained of dysphagia and dysarthria.Microscopically, muscle biopsy showed multifocal or scattered macrophage infiltration and degenerated myofibers. In contrast to general myopathy including inflammatory myositis and rhabdomyolysis, vaccine-induced inflammatory myositis shows a prolonged increase in muscle enzyme levels and multifocal macrophage infiltration with necrosis of the muscle fibers. Symptoms improved with glucocorticoid and immunosuppressive treatment. If vaccinated individuals experience severe and continuous muscle pain and swelling, clinicians should consider vaccine-induced inflammatory myositis, measure the muscle enzyme levels, and perform muscle biopsy for a definite diagnosis.

PURPOSE: Recent advances and wider application of imaging diagnostic techniques, especially ultrasonography(USG) and computed tomography(CT), account for the increasing incidentaloma in adrenal and renal tumors. We have studied these incidentalomas to investigate the incidences, occasions of detection, pathological findings, prognosis and other clinical properties. MATERIALS AND METHODS: The 186 cases of adrenal and renal tumors, treated surgically in Kyoungpook National University Hospital between 1987 and 1997 were reviewed and compared incidentally detected group(59cases) to symptomatically suspected group(127cases). RESULTS: The analysis of 186 cases demonstrated a marked increase in the frequency of incidentaloma from 15.6%(1987?1992) to 43.1%(1993?1997). The proportions of incidentaloma in adrenal and renal tumors were 20.4% in adrenal tumor, 36.4% in renal tumor and 31.7% in total. The chief method of detection was USG(57.6%), followed by CT(33.9%) and IVP(6.8%). The main reasons for examination leading to the diagnosis in incidentaloma were evaluation of unrelated symptoms(44.1%), follow up of other diseases(35.6%), general health check(18.6%) and during other operation(1.7%). In case of adrenal incidentaloma, the mean tumor diameter was larger than in suspected group(4.8+/-3.4cm vs 3.1+/-2.3cm). The main histologic diagnosis of adrenal incidentaloma was adrenal adenoma and hormonally functional tumors were less than suspected group (63.6% vs 88.4%). In case of renal incidentaloma, the mean tumor diameter was smaller than in suspected group(5.3+/-2.1cm vs 8.7+/-2.2cm) and paraneoplastic syndromes were less than in suspected group(20.8% vs 57.1%). The grade and stage of renal incidentaloma were lower and survival rate was higher than suspected group(5 year survival rate, 83.3% vs 64.3%). CONCLUSIONS: These results indicated that abdominal USG or CT should be performed with special attention to adrenal and renal lesions, where at a health examination or evaluation to unrelated disease.

PURPOSE: This study was to evaluate the beam quality of intraoral X-ray equipments used at Yonsei University Dental Hospital(YUDH) using the half value layer(HVL) and the characteristic curve of intraoral standard X-ray film. MATERIALS AND METHODS: The study was done using the intraoral X-ray equipments used at each clinical department at YUDH. Aluminum filter was used to determine the HVL. Intraoral standard film was used to get the characteristic curve of each intraoral X-ray equipment. RESULTS: Most of the HVLs of intraoral X-ray equipments were higher than the least recommended thickness, but the REX 601 model used at the operative dentistry department and the X-707 model used at the pediatric dentistry department had HVLs lower than the recommended thickness. The slopes of the characteristic curves of films taken using the PANPAS 601 model and REX 601 model at operative dentistry department, the X-70S model of prosthodontic dentistry department, and the REX 601 model at the student clinic were relatively low. CONCLUSION: HVL and the characteristic curve of X-ray film can be used to evaluate the beam quality of intraoral X-ray equipment. In order to get the best X-ray films with the least radiation exposure to patients and best diagnostic information in clinical dentistry, X-ray equipment should be managed in the planned and organized fashion.

PURPOSE: Oral UFT is known to be a safe and effective antineoplastic regimen for adjuvant chemotherapy of colorectal cancer. As it sometimes produces upper gastrointestinal symptoms such as anorexia, nausea, vomiting and abdominal pain, medication should be stopped transiently or dosage reduced. UFT-E, an enteric coated granule of UFT was introduced to reduce UGI toxicity. We analyzed the toxicity of UFT and UFT-E prospectively for the purpose of comparison between the two types. METHODS: The toxicity of UFT and UFT-E were evaluated in 83 patients (UFT; 45, UFT-E; 38) with colorectal cancer who underwent curative surgery according to the WHO toxicity criteria. All patients were selected consecutively with patients' approval and by the "Institutional Review Board, Asan Medical Center". RESULTS: The toxicity incidence in UFT-E group was slightly less than that in UFT group without statistical significance. The severity of toxicity seemed to be mild within grade 1 or 2 and most of them toxicity self-limiting. The regimen was completely interrupted in 9 patients (20%) in the UFT group, 3 patients (7.9%) in the UFT-E group due to severe UGI symptoms, prolonged leukopenia, derrangement of liver function and skin rash. CONCLUSIONS: Toxicity rate of UFT-E was not higher than that of UFT. But we cannot prove superiority of UFT-E on UGI toxicity. Oral UFT-E can be administered safely on an outpatient basis without lethal toxicity requiring hospitalization.

Background/Aims: This study aimed to identify the clinical characteristics of patients with concurrent rheumatoid arthritis (RA) and suspected non-tuberculous mycobacterial (NTM) infections as well as determine their prognostic factors. Methods: We retrospectively reviewed the medical records of 91 patients with RA whose computed tomography (CT) findings suggested NTM infection. Subsequently, we compared the clinical characteristics between patients with and without clinical or radiological exacerbation of NTM-pulmonary disease (PD) and investigated the risk factors for the exacerbation and associated mortality. Results: The mean age of patients with RA and suspected NTM-PD was 65.0 ± 10.2 years. The nodular/bronchiectatic (NB) form of NTM-PD was the predominant radiographic feature (78.0%). During follow-up, 36 patients (41.9%) experienced a radiological or clinical exacerbation of NTM-PD, whereas 12 patients (13.2%) died. Combined interstitial lung disease (ILD), microbiologically confirmed NTM-PD, and NB with the fibrocavitary (FC) form on chest CT were identified as risk factors for the clinical or radiological exacerbation of NTM-PD. Hydroxychloroquine use was identified as a good prognostic factor. Conversely, history of tuberculosis, ILD, smoking, microbiologically confirmed NTM-PD, and NB with the FC form on chest CT were identified as poor prognostic factors for mortality in suspected NTM-PD. Conclusions ILD and NB with the FC form on chest CT were associated with NTM-PD exacerbation and mortality. Hydroxychloroquine use may lower the risk of NTM-PD exacerbation. Therefore, radiographic features and presence of ILD should be considered when predicting the prognosis of patients with RA and suspected NTM-PD.
