BACKGROUND: The Helicobacter pylori(H. pylori) is associated with chronic gastritis and is now recognized to be the main factor in the pathogenesis of peptic ulcer disease. The eradication treatment of H. pylori significantly lowers ulcer relapse rate, which is accompanied by important histological change. We evaluated the prevalence of H. pylori infection in upper gastrointestinal diseases. METHODS: Total 491 patients(274 with chronic gastritis, 134 with gastric ulcer, 57 with duodenal ulcer, and 26 with gastroduodenal ulcer) were tested for H. pylori infection by the CLO test, hematoxylin-eosin stain and Giemsa stain. RESULTS: The prevalence of H. pylori infection was 74.0% in male and 58.6% in female. The prevalence of H. pylori infection was 73.2% in 30-59 year-old group and 60.2% in older age group. The sex and age adjusted prevalence of H. pylori infection was 64.7% in chronic gastritis, 69.4% in gastric ulcer, 84.5% in duodenal ulcer and 87.8% in gastroduodenal ulcer. CONCLUSIONS: The prevalence of H. pylori infection of upper gastrointestinal diseases is significantly higher in male, 30-59 year-old group, peptic ulcer and duodenal ulcer than in female, older age group(over 60), chronic gastritis and gastric ulcer, respectively.

Thirty-one distal femoral and nine proximal tibial primary bone tumor patients who had prosthetic replacements were reviewed retrospectively. Average follow-up was thirty-eight months(range: 12- 109 months). There were thirty-two(osteosarcoma: 29, chondrosarcoma: 3) stage IIB lesions and eight 1B lesions(giant cell tumor). Twenty-nine patients were surviving at final follow-up. Overall prosthetic survival was 81%, 27% at 2 and 5 year respectively. Eleven prostheses were revised. The causes of revisions were infection(7), metal failure(2), fracture of host bone(1), and loosening(1). Eight revisions were successful, one was fair, and two patients needed an amputation. Prognostic factors which were analyzed for survival of prostheses were age, sex, location of primary lesion, percent of bone resected, and stage. Only the location of primary lesion showed statistical significance and diabolic pattern of survival curve was noted between two groups in resection length(<40% versus >40%). Average functional score was 26. The tibial side had worse prosthetic survival and a major threat to this procedure was due to infection.

Chronic inflammatory demyelinating polyradiculoneuropathy (CIDP) represents an important acquired condition characterized by progressive, symmetrical, proximal and distal weakness. CIDP is characterized by sensory loss and weakness, areflexia, elevated CSF protein and electrodiagnostic evidence of multifocal demyelination with or without superimposed axonal degeneration. Some reports are made that an antecedent illness in the weeks preceding the onset of symptoms such as upper respiratory syndrome or flu-like illness, gastrointestinal syndrome etc., but intestinal pseudoobstruction as the main clinical feature in CIDP is an uncommon finding. The clinical course is variable. The condition is responsive to immunosuppressive therapy, especially prednisone and plasma exchange. We report a case of intestinal pseudoobstruction secondary to CIDP diagnosed by clinical features, electrodiagnostic study and nerve biopsy pathology.
