A Randomized, Prospective, Comparative, Multicenter Study of Rabeprazole and Ranitidine in the Treatment of Reflux Esophagitis / 대한소화기학회지

BACKGROUND/AIMS: This study was done to evaluate the efficacy of rabeprazole (proton-pump-inhibitor) and ranitidine (H2-receptor antagonist) in the symptom relief and treatment of erosive esophagitis diagnosed by endoscopy. METHODS: A total of 110 patients with typical gastroesophageal reflux disease (GERD) symptoms were enrolled in this multicenter study. They were randomized into rabeprazole group (53 patients) and ranitidine group (57 patients) respectively. The patients in rabeprazole group were given 10 mg of rabeprazole and ranitidine group received 300 mg of ranitidine before breakfast and dinner for 8 weeks. After the end of treatment, we evaluated the endoscopic healing rate of reflux esophagitis and symptomatic improvement. RESULTS: After 8 weeks of treatment, rabeprazole group showed significantly higher complete endoscopic cure rate than ranitidine group (86.8% [46/53] vs. 57.9% [33/57], p=0.001) and higher symptomatic improvement of heartburn (91.2% [31/34] vs. 76.2% [32/42], p=0.085), especially in the first 7 days (76.7% vs. 45.3%, p=0.008). Also, rabeprazole group showed significantly higher improvement of regurgitation symptom than ranitidine group (100% [35/35] vs. 83% [39/47], p=0.009). Both group showed no differences in the improvement of chest pain and globus sensation. All the adverse events (rabeprazole group 4 events vs. ranitidine group 3 events) were mild and there was no abnormality in laboratory test. CONCLUSIONS: In patients with GERD, rabeprazole 10 mg b.i.d. is superior to ranitidine 300 mg b.i.d. in healing of reflux esophagitis and resolving typical GERD symptoms. Rabeprazole is an effective and well-tolerated drug for GERD treatment.

A Case of Triple Synchronous Primary Colon Cancer Diagnosed by Colonoscopy before Operation / 대한소화기내시경학회지

Multiple primary colorectal carcinomas are not rare and occur more often than what can be ascribed to chance, but the frequencies on record vary. The tumors are usually classified as synchronous if they are present at the same time. It is often difficult to detect all these multiple lesions preoperatively:a correct diagnosis is frequently obtained only upon examination of the resected specimen. Triple synchronous primary colon cancer is an exceedingly rare disease. Despite of its rarity, multiple colon cancers should be investigated in the patients in whom clinical or laboratory evidence of colon cancer is suspected. Recently, we experienced one case of triple synchronous primary colon cancer diagnosed by colonoscopy before operation and report here with the review of the literature.

A Case of Totally Calcified Meningioma

Meningioma is a common brain tumor and the associated calcification is frequently found in imaging study. However, calcification of entire tumor bulk in meningioma is very rare finding. We present the clinical and radiological summery of our case which showed totally calcified meningioma and discuss the pathogenesis and clinical significance of such a tumoral calcification.

A Case of Chronic Inflammatory Demyelinating Polyneuropathy in Lupas Nephritis / 대한신장학회잡지

Systemic lupus erythematosus(SLE) is a multisys-temic disease. Peripheral neuropathy occurs in about 10% of patients with SLE. Chronic inflammatory demyelinating polyneurpathy has been reported rarely in SLE. We experienced a case of chronic inflammatory polyneuropathy in lupus nephritis. 32-year-old housewife presented to chronic progressive muscle weakness and heavy proteinuria. Kidney biopsy showed compatible with lupus nephritis (WHO Class V, membranous nephropathy). Nerve conduction studies showed reduction in conduction velocity and sural nerve biopsy revealed demyeli-nating polyneuropathy. Steroid therapy led to improvement in clinical symptoms and proteinuria.

A Case of Left Ventricular Thrombophilia after Anterior Wall Acute Myocardial Infarction

In acute myocardial infarction, mural thrombi occur in approximately 20 per cent of patients who do not receive anticoagulant therapy and about 10 percent of thrombi result in systemic embolization. Threrfore, in acute phase of myocardial infarction, heparinization is considered as essential therapeutic regimen which afterwards acute phase, might have no clinical significance. We experienced a patient with recurrent LV apical thrombi inspite of an sufficient anticoagulation. This patient was treated with primary balloon PTCA and optimal duration of anticoa-gulation with IV heparin was maintained. At predischarge follow-up, TTE revealed huge LV apical thrombi and warfarinization was started. Three episodes of appearance and disappearance of thrombi have been noted and we report this patient as thrombophilia associated with acute myocardial infarction.

Three Cases of Peripartum Cardiomyopathy

Peripartum cardiomyopathy(PPCM) is a rare form of cardiomyopathy of unclear cause that can have life-threatening consequences. Cardiac dilatation and congestive heart failure of unexplained cause may develop during the last month of pregnancy or within the first few months after delivery. It is rare, but it varies among geographic regions. Recent estimates of incidence range from 1: 15,000 in the United States, 1: 6000 in Japan, and 1: 1000 in South Africa. The cause of this disorder is unknown but in some patients endomyocardial biopsy has shown evidence of myocarditis, Necropsy shows cardiac enlargement, often with mural thrombi, endocardial thickening and pericardial effusion, along with histologic evidence of myocardial degeneration, fibrosis and lymphocyte infiltration. However, based on recent data, it seems that endocardial biopsies are currently of minor diagnostic and therapeutic benifit in patients with PPCM. The symptoms, signs, and treatment are similar to those in patients with idiopathic dilated cardiomyopathy, but thromboembolic complications are particularly common. The mortality rate is quite variable but may be as high as 25 to 50 percent. We experienced three case of peripartum cardiomyopathy after delivery. The patients were treated with digitalis, vasodilator and diuretic, which induced improvement of the clinical and echocardiographic finding.

The Role of Helicobacter pylori in Cirrhotic Patients with Peptic Ulcers / 대한소화기내시경학회지

BACKGROUND AND AIMS: The overall age-matched incidence of gastroduodenal ulcers was considerably higher in cirrhotic patients compared to the general population. There are several possible underlying mechanisms which may explain the ulcerogenic factors in cirrhotic patients. Recently, Helicobacter pylori (H. pylori) was proven as the cause of peptic ulcer disease in the general population. But the role of H. pylori infection in the pathogenesis of peptic ulcers of cirrhotic patients has not been clearly elucidated. The purpose of this study was to determine the role of H. pylori infection in cirrhotic patients with peptic ulcers. METHODS: From 1995 to 1997, 105 patients with histologically or radiologically proven liver cirrhosis (LC) who received panendoscopic examination due to presence of any upper gastrointestinal symptoms were studied. During endoscopic examination, a CLO (campylobacter like organism) test or gastric antral mucosal biopsy was performed in all patients. The severity of LC assessed by Child's criteria revealed that 31 patients had Child's A, 26 patients Child's B, and the remain 48 patients, Child's C. Child B or C was classified as decompensated LC. An esophageal varix was present in 73 patients or absent in 32. RESULTS: There was no statistical difference in the H. pylori prevalance between the ulcer group and non-ulcer group (67% vs 52%). In Child A group, the H. pylori prevalence was significantly higher in the ulcer group when compared with the non-ulcer group (87% vs 50%, p<0.05). In contrast, in the Child B or C group, there was no statistical difference between the ulcer group and non-ulcer group. In the abscence of esophageal varix, the ulcer group showed significantly higher prevalence of H. pylori than the non-ulcer group (87% vs 59%, p<0.05). But in the esophageal variceal group, there was no significant difference in the H. pylori prevalence between the ulcer and non-ulcer group (60% vs 40%). CONCLUSIONS: These observations suggest that H. pylori infection may play a role in the pathogenesis of peptic ulcer in compensated cirrhotic patients. However, in cirrhotic patients with decompensation or an esophageal varix, the association between H. pylori infection and peptic ulcers was weak, so other factors (portal hypertension etc.) should be considered as more potent etiology of peptic ulcers in cases of decompensated cirrhosis.
