Injuries in the industries has been steadily increasing in this country in recent years. Injuries in the industries intricate in accoriance with the industrial environment, mechanism of injuries and the other factors of employees. In 6 years 201 patients with industrial injuries underwent treatment in the Department of Orthopaedic Surgery of the National Medical Center, and the result of treatment is reported in this paper. 1. 70 cases out of 201 cases were in the age group between 21 to 30 year. 186 cases were male and 15 were female. The incidence is remarkably higher in male. 2. In 80 cases the injuries were caused by machinery with pressor parts. The patients were chiefly manual workers in factories. 3. Of 280 injuries, 148 (62.8%) were upper extremities, 105 (37.5%) were lower extremities and 27 (96%) were trunks. The most common site of injuries was hand. 4 Of 146 injuries with fractures, 94 were treated by manual reduction and cast, and 52 were treated by open reduction. 5. Treatment for open wounds was debridement followed by delayed primary closure and/or skin graft. The primarily closed open wounds by local clinics were observed and treated according to wound condition. 6, 17 cases out of 22 phalangeal bone fractures were treated by manual reduction and splint. 5 cases were treated by K-wire internal fixation, among them 3 cases had to be treated by amputation. 7. Incidence of early camplication was considerably high with 137 sites out of 280 sites and the late complication was 79 sites after treatment of the early complications.

Malignant thymoma is usually manifested as a mediastinal mass. Occasiomally, these tumors may be associated with a variety of systemic syndromes, such as myasthenia gravis, pure red cell aplasia or hypogammaglobulinemia. However, it is generally accepted that thymomas rarely metastasize and the frequency of extrathoracic metastasis has been reported as 1 to 15%. In general, nuclear changes of tumor cells such as enlarged size, irregular shape and altered textures are determining feactors in the assessment of the grade of malignancy. We experienced a case of malignant thymoma of anterior mediastinum in a 35-year-old woman. After 3 years, she developed recurrent malignant thymoma in the right supraclavicular area, diagnosed by aspiration biopsy cytology.

Juvenile dermatomyositis is a common inflammatory muscle disease of childhood, characterized by weakness in proximal muscles and specific skin rash. In case of juvenile dermatomyositis without characteristic clinical features, non-invasive imaging tools such as (99m)Tc-HDP three-phase bone scan are very helpful in diagnostic workup of myopathies. We report a case of 13-year old female with juvenile dermatomyositis, in which (99m)Tc-HDP three-phase bone scan was useful in diagnosis and assessing therapy response.

OBJECTIVE: Helicobacter pylori (H. pylori) has been implicated in the pathogenesis of chronic gastritis, gastric ulcer, duodenal ulcer and gastric cancer. Histological examination and culture are considered to be the most specific tests, and rapid urease test and serological test are rapid but less specific tests. 'I he aim of this study was to investigate the efficiency of the polymerase chain reaction (PCR) assay as a procedure for the diagnosis of H, pylori infection in gastric biopsy specimens. METHODS: Biopsy specimens were obtained from the gastric antrum within 2cm from the pyloric channel of 42 patients during endoscopy and submitted for the histological examination, CLO test, and PCR assay. At the same time, another biopsy specimens were obtained from the lesion for the diagnosis of the diseases. Also, blood was sampled for the measure of the value of IgM and IgG. RESULTS: As the result of the histopathological examination, chronic gastritis was diagnosed in 13 patients, gastric ulcer in 11, duodenal ulcer in H, and gastric cancer in 10. By the histological examination of the antrum, H, pylori were found in 77% of chronic gastritis, 55% of gastric ulcer, 75% of duodenal ulcer, and 40% of gastric cancer. As a whole, the bacteria was identified in 62%, 60%, 88%, 90%, 69% of patients by histological test, CLD test, IgM, IgG, and P(;R respectively. The gold standard we used for the presence of bacteria was histological examination. Sensitivity, specificity, positive predictive value, ancl negative predictive value for PCR assay were 92%, 69%, 83% and 85% respectively. The results of other test were as follows. CLO test: 89%, 88%, 92%, 82%, IgM:92%, 19%, 65%, 60%, IgG:100%, 25%, 68%, 100%. CONCLUSION: CR is a very sensitive but some- what less specific test for the detection of H. pylori. This is mainly due to the contamination of H. pylori during endoscopy and biopsy. So, minimization of the contamination would make PCR clinically useful test.

Many disorders and abnormalities are accompanied by cavitary lesoin of the lung and one of the most common causes of cavitary lung disease are primary and metastatic lung neoplasms. but cavitary formation of primary lung cancer is not frequent and cavitary or cystic pulmonary metastases of this is also rare. We report a case of cavitary pulmonry metastases of primary lung cancer proven by bronchoscopic biopsy and chest CT. The patients was 60 year-old heavy smoker who had never been underlying lung diseases 7 years ago and complained chronic cough. The chest CT showed primary lung cancer in right low lobe with multiple cavitary or cystic metastases in both lungs and multiple lymphatic metastases.

Salmonella infection occurs in 5 different clinical forms; gasteroenteritis, enteric fever, bacteremia, chronic carried state and localization at one or more sites. Extraintestinal pyogenic infections caused by salmonella species include soft tissue abscesses, bone and joint infections, cholecystitis, liver abscess and splenic abscess etc. Pancreatic abscess due to Salmonella typhi is a very rare extraintestinal manifestation of salmonellosis. Infection pathways may be considered as reflux of infected bile through the pancreatic duct, hematogenous spread from a distant site or lymphatic spread from the intestinal tract. Treatment of pancreatic abscess needs surgical intervention and antibiotics therapy. We have experienced a case of a 40-years-old female with pancreatic abscess due to Salmonella typhi. She was treated with ultrasonography-guided catheter drainage and intravenous ceftriaxone for 18 days. After 14 days, the sonographic examination revealed the abscess cavity in pancreas almost disappeared. We report this case with review of literatures.

BACKGROUND/AIMS: Lamivudine, a nucleoside analogue has been widely used as an effective antiviral agent for the treatment of patients with chronic hepatitis B infection. However, the YMDD motif mutation of HBV polymerase resistant to lamivudine very frequently occurs after long-term use of lamivudine. It is well known that the mutation is selected by the lamivudine. We hypothesized that a few mutant strains of YMDD motif are present as quasispacies before the lamivudine treatment, are selected by the treatment, and breakthrough during treatment. We investigated the prevalence of the YMDD motif mutants in patients with chronic hepatitis B infection who had not been treated by antiviral agents before. METHODS: The study included the serums of 40 patients with chronic heptitis B infection, which stored at -70 degrees C. Thirty-four patients had chronic hepatitis and 6 patients had cirrhosis. Thirty-one patients were diagnosed by liver biopsy. The average age and range were 29 years and 13-57 years respectively. None had taken any antiviral agents before. To detect YMDD mutants, YVDD (M552V), and YIDD (M552I), we used direct sequencing and the restriction fragment length polymorphism (RFLP) method. RESULTS: The YMDD mutant was detected by RFLP method in 7.5% (3/40) of the patients with chronic hepatitis B infection, in two patients with chronic hepatitis and one with cirrhosis. All were YMDD+ YIDD mutants. CONCLUSIONS: The YMDD motif mutation occurs spontaneously without antiviral therapy in patients with chronic hepatitis B infection.

BACKGROUND: Compared with classic achalasia, vigorous achalasia has been defined as achalasia with relatively high esophageal contraction amplitudes, often with minimal esophageal dilation and prominent tertiary contractions on radiographs and the presence of chest pain. The lesser success of pneumatic balloon dilation, also, has been reported for the subset with vigorous achalasia. Nevertheless, some authors have questioned the usefulness of making this distinction. We evaluated the difference of clinical manifestations and response to pneumatic balloon dilation between classic and vigorous achalaisia. METHODS: 28 cases involving patients with achalasia who underwent balloon dilation treatment were available for the review of their clinical findings, radiographic, manometric, esophageal scintigraphic parameters. Patients with vigorous achalasia [n=10] were defined by contraction amplitude >or=37 mmHg on esophageal manometry and patients with classic achalasia [n=18] as contraction amplitude <37 mmHg. RESULTS: Both groups of patients had substantial overlap in clinical findings, radiographic, manometric and esophageal scintigraphic parameters. The success rates of balloon dilation, also, were similar for both groups (classic vs vigorous, 78% vs 70%). CONCLUSION: It is concluded that the distiction of achalasia as classic and vigorous by an amplitude criterion is arbitrary and not useful.
