Orthotopic rat liver transplantation using different combinations of four inbred strains.
Orthotopic liver transplantation in the rat was performed using different combinations of four inbred strains. The influence of infection and rejection on the early fate of the grafts were studied with a particular emphasis on histomorphological changes and their diagnostic interpretation.

Hepatocellular carcinoma in type I glycogen storage disease.
Patients suffering from Type I glycogen storage disease frequently develop hepatic tumors. Some of these were classified as carcinoma, with the majority of tumors representing benign adenomata. However, no evidence exists of malignant transformation of adenomata in these patients. Here, we describe the occurrence of a hepatocellular carcinoma in the adenomata-bearing liver of the elder of two sisters suffering from Type I glycogen storage disease at the age of 20 years, 6 years after the diagnosis had been made. Surprisingly, alpha-fetoprotein levels were normal throughout the entire course of this patient, whereas the younger sister had elevated levels despite the absence of malignant lesions. Thus, the clinical significance of alpha-fetoprotein remains unclear in both cases. Nocturnal feeding, although performed continuously over the 6 years after the diagnosis, had obviously failed to prevent the development of hepatic tumors in both patients.

[Necrotizing enterocolitis: a 12-year retrospective study].
UNLABELLED: Necrotizing enterocolitis (NEC) is the most relevant intestinal acquired complication during the neonatal period. Due to the improvements in perinatal medicine during the last decade, we wanted to work out possible differences in the incidence, diagnosis and clinical courses of NEC during a 12 years period. PATIENTS AND METHODS: All premature or term newborns were eligible for the study, if a necrotizing enterocolitis > or = stage 2a according to Bell was diagnosed between January 1980-December 1991. RESULTS: During the study period, 90 preterm or term newborns were treated for necrotizing enterocolitis, 19 infants were admitted to our hospital for therapy of established NEC from other hospitals. Forty-five infants had a birthweight of < or = 1500 g. During the years 1987-1991 there was an increase in the incidence (4-12/year, median 9/year, compared to 0-6, median 3/year during the period 1980-1986). This was paralleled by an increase in very low birthweight infants admitted to the NICU (1980-1986: 35-45/year, 1987-1991: 83-108/year). Prominent clinical signs: abdominal distension (85 infants), increased gastric residuals (72), bright blood from rectum (56). Median time of manifestation in infants < or = 30 weeks was 17 days, for infants of 31-34 weeks 8 days and for infants of > or = 35 weeks of gestation 4 days. Eleven infants were fed parenterally exclusively before NEC, 12 infants received exclusively breast milk, 67 formula. Surgical treatment was indicated in 51 infants (indication: intestinal perforation or peritonitis diagnosed by abdominal paracentesis). Seventy-one infants survived, in 17 infants who died, NEC or secondary disorders were the main cause. CONCLUSION: With increasing numbers of very preterm infants, the relevance of NEC becomes more and more important. Concepts of prevention and early diagnosis further have to be worked out.

Multi-visceral resection for locally advanced gastric cancer.
Fifty-three of sixty-four patients who underwent gastrectomy for gastric carcinoma presented with advanced gastric cancer. 8 patients underwent palliative gastrectomy. In 17 patients gastrectomy and lymphadenectomy was performed. In 28 patients with locally advanced gastric carcinoma, extended resection was performed. Patients who underwent splenectomy were only included if tumorous adherence to the spleen was present. Hospital mortality and morbidity were 3.6% and 25% in extended resection and 5.9% and 18% in gastrectomy and lymphadenectomy alone. R0 resection was performed in 26/28 and in 16/17 patients, respectively. In R0 (complete) resections the mean one and two-year-survival rates were 64% and 44% in extended resection, and 67% and 47% in gastrectomy and lymphadenectomy. In patients (11) with residual tumour (R1/R2) mean one and two-year-survival rates were 27% and 0%, respectively. If complete resection (R0) is achieved, extended resection for locally advanced gastric carcinoma provides survival time, which is comparable, stage for stage, with survival rates observed after R0 resection for cancer limited to the stomach.
