Clinicopathologic differences between early gastric remnant cancer and early primary gastric cancer in the upper third of the stomach

BACKGROUND/AIMS: This study was designed to clarify the clinicopathologic characteristics and survival in early gastric remnant cancer and compare with early primary cancer in the upper third of the stomach. METHODOLOGY: Twenty-five patients with early gastric remnant cancer, who underwent resection at Kanagawa Cancer Center and First Department of Surgery, Yokohama City University between 1974 and 1996 were evaluated in this study. Various clinicopathologic characteristics, such as age, sex, symptoms, size of tumor, depth of invasion, lymph node metastasis, cell differentiation, and survival were investigated and early gastric remnant cancer was compared with early primary cancer in the upper third of the stomach. RESULTS: According to the macroscopic type, protruded type such as I or II type accounted for a great majority in early gastric remnant cancer, while II c depressed type was common in early primary cancer in the upper third of the stomach, comprising 64.2% of all cases. Pathological examination disclosed that well-differentiated carcinoma and mucosal carcinoma were more frequently observed in early gastric remnant cancer than in early primary cancer in the upper-third of the stomach. The 5-year survival rate was 83.5% for early primary cancer in the upper-third of the stomach. In contrast, no patients experienced recurrence after operation for early gastric remnant cancer. CONCLUSIONS: From the view point of clinicopathological evaluation, gastric remnant cancer is a special from of gastric cancer. A follow-up program is important in order to detect early gastric remnant cancer. A low incidence of lymph node metastasis suggests that endoscopic mucosal resection of the tumor or limited operation could be performed under strict indication.     

Perioperative management of benign hepatic tumors in patients with glycogen storage disease type Ia

Glycogen storage disease type Ia (GSD-Ia; von Gierke disease) is an inherited disorder caused by glucose-6-phosphatase deficiency, and there have been some reports of hepatic tumors in patients with this disease. We report two patients with benign hepatic tumors with GSD-Ia. One is a 19-year-old man who underwent segmentectomy 4 for a focal nodular hyperplasia, and the other is a 31-year-old woman who underwent segmentectomies 3, 5, and 6 for hepatic adenomas. Two significant perioperative complications, resulting from the carbohydrate metabolic disorders, hypoglycemia and metabolic acidosis, occurred in both patients. We managed the metabolic complications successfully by administering a sufficient volume of glucose intravenously. Close perioperative monitoring of blood glucose and lactate concentrations is essential in the perioperative management of patients with GSD-Ia. The intravenous administration of glucose, starting with a smaller dose and then increasing the dose, is adequate management for lactic acidosis with or without hypoglycemia during the perioperative period.     

Clinical features of liver disturbance in rheumatoid diseases: clinicopathological study with special reference to the cause of liver disturbance

Background: Background: Liver disturbance in rheumatoid diseases results not only from liver disease associated with the rheumatoid diseases themselves but also from various other causes. This study aimed to elucidate the clinical features of liver disturbance in rheumatoid diseases, focusing on the cause of this disturbance. Methods: A clinicopathological study was performed in 306 patients (106 with systemic lupus erythematosus, 71 with Sj?gren's syndrome, 59 with rheumatoid arthritis, 27 with scleroderma, 30 with polymyositis, and 13 with polyarteritis nodosa). Results: Liver disturbance occurred in 43% of these patients and resulted from various causes. Its degree and duration varied from one cause to another. Liver disease associated with rheumatoid diseases was the leading cause of the liver disturbance in these patients and was characterized by mild and transient liver disturbance (maximum alanine aminotransferase [ALT] level during the study period, 68 ± 8 IU/ml; maximum alkaline phosphatase [ALP] level, 410 ± 31 IU/ml; duration of liver disturbance, 6 ± 2 months). Most patients with this type of liver disease showed minimal change in liver histology, although two-thirds of those evaluated by the international scoring system for autoimmune hepatitis (AIH) were classified as “probable” or “definite”. Eight of 14 patients with histologically proven chronic hepatitis or cirrhosis were infected with hepatotropic virus (7 with hepatitis C virus [HCV] and 1 with hepatitis B virus [HBV]). Five of 9 patients in whom the hepatic lesion progressed had hepatotropic virus infection (4 with HCV and 1 with HBV), and the other 4 patients suffered from autoimmune liver diseases. Conclusions: Liver disease associated with rheumatoid diseases was the leading cause of liver disturbance in these patients and was characterized by mild and transient liver disturbance, whereas progressive liver diseases were often associated with hepatotropic virus, mainly HCV, or autoimmune liver diseases. Liver histology is indispensable for differentiating AIH from liver disease associated with rheumatoid diseases. Received: August 27, 2001 / Accepted: January 7, 2002

Aplastic Anemia in a Patient with Cronkhite-Canada Syndrome

Cronkhite-Canada syndrome (CCS) is a rare polyposis disorder accompanied by alopecia and onychodystrophy. A 63-year-old man with a history of CCS and repeated embolism developed progressive thrombocytopenia and mild anemia. Laboratory testing, a bone marrow examination, and magnetic resonance imaging of the spine resulted in a diagnosis of concurrent aplastic anemia (AA). Paroxysmal nocturnal hemoglobinuria (PNH)-type cells were detected in a peripheral blood specimen. In addition, human leukocyte antigen (HLA) included DRB1*15:01 and DRB1*15:02. Mesalazine was discontinued in consideration of possible drug-induced pancytopenia. Immunosuppressive therapy ameliorated both the gastrointestinal symptoms of CCS and pancytopenia. A common autoimmune abnormality might underlie both CCS and AA.     

Isolation of MRSA from inpatients, staff and environment in the hospital]

The state of MRSA contamination of inpatients, hospital staff, and the hospital environment was evaluated. Nasal, pharyngeal, and digital samples from 182 patients admitted in September and October, 1990, and 288 hospital staff members and sputum, urine, and feces of the inpatients were cultured. Environmental contamination was examined in samples collected from the air by air sampling and from the floor by the wiping method. The MIC and the coagulase type of the MRSA obtained were determined, and their relationships were evaluated. MRSA was detected in 9.5% of nasal samples, 7% of pharyngeal samples, 10% of sputum samples, 0% of urine samples, and 2.6% of fecal samples from the 182 inpatients. It was detected in 4% of nasal samples, 0.7% of pharyngeal samples, and 1% of digital samples from the 288 hospital staff members. From the environment, MRSA was detected from hospital rooms of the surgery and neurosurgery wards, the nursing room and corridors of the obstetrics and gynecology ward, and the recovery room of the urology ward. The coagulase type of the MRSA obtained was the primarily type II regardless or whether the samples were obtained from the subjects or the environment. Concerning the drug sensitivity, many MRSA strains were highly resistant to DMPPC and FOM, but the sensitivity to RFP was 0.1 microgram/ml or less in all strains except for one highly resistant strain (200 micrograms/ml or above).(ABSTRACT TRUNCATED AT 250 WORDS)
