Primary carcinoma of the appendix.

Primary adenocarcinoma of the appendix is rare and less than 200 cases are on record. The present material consisted of 20 cases collected from different hospitals. The cases are described in respect of sex and age-distribution, symptoms, treatment and prognosis. Of 7 patients with malignant mucocele, 6 subjected to appendectomy only, were still alive 5 years after the operation. Of 12 patients with colonic type of adenocarcinoma, 3 had been treated with appendectomy only. Of these, 2 were still alive 5 years after the operation. The remaining 9 patients had undergone right hemicolectomy. Only one of them was alive 5 years after the operation. A compilation of a further 39 cases garnered from the literature, however, showed that 60% had survived at least 5 years after right hemicolectomy, compared with 46% after appendectomy alone. Appendectomy alone is probably a sufficiently radical operation for malignant mucocele provided the tumor has not grown through the submucosa and that it is confined to the tip of the appendix. Right hemicolectomy is indicated for the colonic type of adenocarcinoma.

Knowledge and communications infrastructure and regional economic change

Abstract This study is concerned with an analysis of the relations between infrastructure and productivity. It is based on a production function approach, permitting variable returns to scale with respect to the quantity and quality of labor. The infrastructural capacity of a region is represented by a geometric aggregate of air, road, rail, building capital and R&D capacities. A non-linear econometric procedure is used to estimate the influence of infrastructure upon gross productivity of regions.

Carcinoma of the colon in children: A report of six new cases and a review of the literature

Of six children with carcinoma of the colon, none had ulcerative colitis or a family history of carcinoma of the colon or colonic polyposis. In 75 cases traced in the literature, a common early symptom of carcinoma of the colon in children is acute, crampy abdominal pain. At laparotomy for suspected appendictis, the possibility of the acute pain being due to carcinoma of the colon should be borne in mind. Otherwise the symptoms of carcinoma of the colon in children do not differ substantially from those in adults. The prognosis is unfavorable; in only 2.5% of the cases on record did the children survive 5 yr after the operation.

Knowledge, Nodes and Networks: An Analytical Perspective

This paper treats knowledge stocks as endogenous public goods. Rather than being used up in the process of production, knowledge is expanded and enhanced by way of exchange processes on a network consisting of nodes and links in geographical space. The nodes take the form of human settlements such as villages, towns or metropolitan regions, and the links between nodes consist of transportation routes and communication channels which facilitate knowledge acquisition and knowledge expansion.

Volvulus of the cecum.

A series of 37 patients with cecal volvulus treated at three different Swedish hospitals during the years 1952-1973 is presented. The symptoms, physical findings and radiologic features are presented. The associated factors found at operation are described and their possible role in provoking torsion is discussed. In 5 patients the idagnosis did not become clear untio autopsy. Thirty-two patients were subjected to operation. The operation consisted of detorsion in 11 cases, cecopexy in 10, cecostomy in 3 and cecopexy plus cecostomy in 3 patients. The remaining 5 patients were subjected to right sided hemicoloectomy. Of these 5 patients one died postoperatively. There were 6 postoperative deaths after other forms of surgery. The survivors were followed, and the mean followup period was 7 years. There was recurrence in only two patients, both treated with cecopexy. The controversial problem of the preferable surgical method is discussed and a review is given of results in series reported during the last 15 years. It was concluded that when the bowel is viable, cecopexy is the treatment of choice while hemicolectomy should be performed in cases with gangrene.

The Emerging C-Society

Industrial and regional development in Europe has been shaped by the growth and change of logistical systems, i.e. the slow but steady evolution of logistical infrastructure. Logistical infrastructure is in this context defined to be equipment and networks used for the transportation and distribution of commodities, people, information, and knowledge. The logistical system of an economy also includes the infrastructure within urban nodes.

Lipomatosis of the ileocecal valve

Ten cases of lipomatosis of the ileocecal valve are reported. The age of the patients (7 females and 3 males) varied between 37 and 70 years. The chief complaint was abdominal pains, most often in the right lower quadrant. Other symptoms were obstipation, blood in the stools, flatulence, abdominal tenderness, and diarrhea. Roentgenologic examination showed radiolucent defects in the ileocecal region of all the patients. Ileocecal resection was performed in 8 cases, whereas a polypoid mass was excised at cecotomy in 2 of the patients. Gross and microscopic examinations showed a diffuse fatty infiltration in the submucous layer of the ileocecal valve, with or without a polypoid projection into the cecum. There was no capsule around the fatty tissue, and no histologic signs of malignancy occurred. It is emphasized that lipomatosis of the ileocecal valve that has been treated surgically has a good prognosis and that it is important to differentiate this condition from true benign or malignant tumors.
