PURPOSE: To evaluate the results of femoral component revision with proximal modular prosthesis in 32 hips. MATERIALS AND METHODS: Thirty-two hips of thirty patients, which were revised with proximal modular femoral component due to aseptic loosening, were investigated. These patients were followed radiologically and clinically at least for two years. RESULTS: These patients were followed for an average of 2.8 years. Complications included four intraoperative femoral fractures (three at proximal, one at distal), two progressive subsidence, one infection, and one non-union and one fibrous union of the greater trochanter. Of the 32 hips, three hips were re-revised due to progressive subsidence in two and recurrent dislocation in one. Acute postoperative infection developed in one patient, who suffered from diabetes mellitus. Radiographically, satisfactory results were noted in 27 (84.7%) of 32 hips at the latest follow-up. Harris hip score was improved from an average of 47 points to an average of 93 points. CONCLUSION: This study provides encouraging results in femoral component revision with proximal modular prosthesis.

OBJECTIVE: The accuracy of analytical results of blood and urine heavy metals came out to the main issue on occupational health from late eighties. The discrepancy of the results for same samples from different laboratories made the diagnosis for occupational diseases be unreliable. Therefore, a quality control program for analysis of samples taken from workplace had been introduced in Korea since 1992. This study aims to show the quality control program f'or analysis of blood and urine samples and its proficient rates from 1992 to 1999 and to know how they have been being used in occupational health. METHODS: The quality control program runs twice a year with mandatory items of blood lead and urine hippuvic acid and voluntary items of blood cadmium and manganese and urine mandellic acid and methyl hippuric acid. Participant laboratories are receiving three levels for each items and two out of three samples have to be qualified for being a proficient laboratory for the item. The acceptable range of blood lead and urine hippuric acid is +/-15% and that of the others is within 3 SD(standard deviation) from the reference values. RESULTS: The proficient rates of blood lead and urine hippuric acid was 89%, 90%, repectively, however those of the other voluntary items have been from 51% to 62%. The proficient rates of urine mercury and urine N-methylformamide(NMF), which are introduced since 1999, were very poor. Urine hippuric acid and blood lead were analyzed frequently for the purpose of biological monitoring conducting by special health examination organizations. Urine and blood manganese and urine metabolites of trichloroethylene, urine phenol, methylhippuric acid and cadmium were followed. CONCLUSIONS: In conclusion, the quality control program for biological monitoring has dramatically improve the ability of analysing blood and urine samples and eventually contributes to diagnose occupational diseases and to prevent occupational poisoning. However, some biological monitoring data, such as urine manganese, mercury and NMF, have been still reported from laboratories that were not accepted as a proficient laboratory.

PURPOSE: To compare the diagnostic accuracy between fine needle and large cutting needle biopies. METHODS & MATERIALS: Chest lesion was biopsied consecutively by 19 G or 22 G fine needle and 14 G large cutting needle with interval of 10-20 min. 119 patients confirmed by operation or clinical follow-up were evaluated. RESULTS: There were 65 patient confirmed as malignant lesion and 54 confirmed as benign lesions. Diagnostic accuracy was 87.7%(57/65) for malignancy and 85.2%(46/54) for benign lesion with fine needle. With large cutting needle, it was 90.8%(59/65) for malignancy and 88.9%(48/54) for benign lesion. In the benign lesion, specific diagnostic accuray was 48.1%(26/54) with fine needle, and 64.8%(35/54) with large cutting needle biopsy, respectively. Complications were hemoptysis(n=13, 10.9%), pneumothorax(n=7, 5.9%) and mild to moderate chest pain. Although, it is impossible to compare the complications by the two types of biopsy on same lesion, 10 cases of immediate hemopytsis and more severe chest pain occurred when large cutting needle biopsy was done. CONCLUSION: No significant difference in diagnostic accuracy between fine needle and large cutting needle biopsies was observed in malignant lesion. In benign lesions, larger sample volume may increase the chance of obtaining a specific diagnosis but has no influence on overall diagnostic accuracy of benignity. Thus, we believe that fine needle aspiration biopsy is an accurate, safe, and more tolerable means to be performed as first step for diagnosis of chest lesions.

PURPOSE: Many kinds of substances are produced on vascular endothelial activation. The aim of this study is to confirm an increase in Endothelin-1 (ET-1), the most potent vasoconstrictor, which is produced by endothelial activation, in patients with chronic anal fissure and to infer the relationship between ET-1 and anal fissure chronicity. METHODS: The study groups are divided into three different groups with 30 subjects each. Group 1 is comprised of healthy volunteers, group 2 of chronic anal fissure patients, and Group 3 of patients with higher than 3rd degree hemorrhoids. Blood samples were taken to measure the ET-1 levels in subject's serum and to compare the results with those for the control groups. RESULTS: Among the 90 subjects, 38 were male, and 52 were female. The average age was 36.8. The average ET-1 level marked 1.47 +/- 0.78 pg/mL for male subjects and 1.16 +/- 0.47 pg/mL for female subjects (P = 0.02). The average ET-1 level in the patient groups is as follow: 1.21 +/- 0.44 pg/mL in group 1, 1.46 +/- 0.83 pg/mL in group 2, and 1.20 +/- 0.56 pg/mL in group 3 (P = 0.14). CONCLUSION: Group 2, the chronic anal fissure patient group, showed a higher ET-1 level than groups 1 and 3, the control group and the hemorrhoid patient group, but this difference had no statistical significance.

Acute suppurative thyroiditis is an uncommon condition because the thyroid gland is remarkably resistant to infections. In children, anatomic defects, such as a left piriform sinus fistula, predispose subjects to this infection. The number of reports on acute suppurative thyroiditis and an anterior neck abscess due to piriform sinus fistula have recently increased. The sinus may be overlooked for years, with the patient receiving multiple procedures before a proper diagnosis is made and the condition correctly treated. Herein, we report our experience of a case of recurrent suppurative thyroiditis associated with piriform sinus fistula, and reviews the embryological development of the sinus, as well as clinical symptoms and treatment of acute suppurative thyroiditis.

An enteric duplication cyst is an unusual, benign congenital lesion of uncertain etiology. Duplications may be located anywhere along the alimentary tract from the mouth to the anus. Esophageal duplication cysts account for 10~15% of all duplications, and combined autopsy series have estimated an incidence of 1 in 8,200. They can occur in any position related to the esophagus, but are most common in the lower third arising from the embryonic foregut, and are represented by a common spectrum of derivatives, such as bronchogenic cysts and ciliated hepatic foregut cysts. Many cases of esophageal duplication cysts have been reported, nearly all of which were either completely or partially within the thoracic cavity. However, reports of complete intra-abdominal cysts, so called subdiaphragmatic esophageal duplication cysts, are rare, especially in children. Herein, we report such a case that occurred in a 10-year-old boy, where a duplication cyst arose from the lower esophagus, remaining entirely confined within the abdomen of a child. The boy presented with a 2 month history of intermittent epigastric pain, nausea and vomiting. After surgical excision, the symptoms disappeared, with the diagnosis confirmed by histologic examination and fitting to the pathological criteria.
