Diverticular disease of the large intestine in Northern Norway.

In 280 unselected necropsies on patients over 20 years of age in Northern Norway, diverticular disease was present in 25% of the males and 43% of the females. The frequency of diverticular disease increased in both sexes by age. Both the frequency of diverticular disease and the average number of diverticula per case with diverticular disease were higher in females than in males in all age groups. The sigmoid was the most frequent site of diverticula in both sexes and for all ages, and the average number of diverticula per diverticulum-bearing segment was also highest in the sigmoid for all ages and in both sexes. The average number of diverticula in the sigmoid of affected individuals increased with age and with the number of segments involved. Diverticular disease was not associated with adenomas of the large intestine or with malignant or benign neoplasms elsewhere in the body or with any of the common diseases thought to be related to a Western type of diet, except with cerebrovascular disease.

Polyps of the large intestine in Northern Norway.

In unselected autopsies on 171 males and 109 females over 20 years of age in Tromsø, Northern Norway, adenomas of the colon and rectum were present in 40% of the males and 33% of the females. The frequency of adenomas increased with age in both sexes. Hyperplastic polyps were found in 20% of all cases with no variation in frequency with sex or age. Before the age of 65 most adenomas were located in the distal half of the large intestine in both sexes. After 65 years in males and 75 years in females the predilection site was shifted to the proximal half of the large intestine. The average size and grade of atypia of adenomas increased with age, but no significant difference in grade of atypia was found between the proximal and distal halves of the large intestine. The occurrence of adenomas was not associated with any of the common chronic diseases thought to be related to a western-style diet or to malignant or benign neoplasms elsewhere in the body. A significant association was found between the occurrence of adenoma and high body weight. The findings support the role of adenomas as precursors of colorectal carcinoma.

Malignant appendiceal carcinoid with intussusception of the base manifesting as a cecal tumor: report of a case.

A case of an appendiceal carcinoid tumor with regional lymph-node metastases is presented. The size of the tumor was remarkable, as the appendix was infiltrated throughout its length. The proximal part of the appendix was intussuscepted into the cecum. Preoperatively, the lesion was diagnosed as a polypoid tumor of the cecum. A primary right hemicolectomy was carried out.

Natural history of adenomas.

One-third of individuals over the age of 55 years have single or multiple colorectal adenomas. During a subsequent period of 10 years, 3-5% of adenoma-bearing individuals will probably develop a carcinoma. The rather low conversion rate from benign to malignant disease indicates that most individuals with adenomas will never develop colorectal carcinoma. More knowledge is required to predict the outcome of the individual adenoma in a given patient. This will probably be obtained by increasing progress within gene technology and through large prospective follow-up studies of adenoma-bearing patients.

Lipid entrapment and cellular changes in the rat myocard, lung and liver after long-term parenteral nutrition with lipid emulsion. A light microscopic and ultrastructural study.

We have demonstrated organ damage after long-term administration of lipid-based parenteral nutrition, possibly initiated by intravascular pooling of lipid and phagocytes, in both rats and pigs. To evaluate whether accumulation of lipid could simply be caused by mechanical filtration, a comparative study of three separate capillary beds was performed. Rats were given lipid emulsion (n = 5) or isotonic saline (n = 4) through central venous catheters for 3 weeks. Using both light and electron microscopy, lipid accumulation and structural changes in the rat myocard were compared to those in the lung and liver. The study provides evidence that within myocardial capillaries both peripheral blood monocytes and endothelial cells performed phagocytosis of lipid droplets following administration of lipid emulsion, but no large-scale intravascular pooling of lipid resulted. Morphometry of the myocard detected no lipid increase in the myocytes from the rats given lipid emulsion compared with controls and in neither were there any stigmata of vasculitis or myocardial damage, in contrast to the lung and liver, where intravascular pooling of lipid and phagocytes was seen. This indicates that phagocytosis was an important mechanism involved in entrapment and elimination of lipid.
