Surgical treatment of midgut nonrotation in the adult patient.

For a period of four years, five adult patients with nonrotation of the intestine and midgut volvulus have been treated. Two distinct clinical presentations were encountered. The chronic presentation is that of colicky abdominal pain, often present for many years, which is corrected by surgical intervention. The acute presentation with strangulation of the intestine may occur without pre-existing symptoms. Knowledge of this entity and a high index of suspicion are necessary for the diagnosis because massive gangrene of the intestine may result from a delay in treatment. Prophylactic surgical treatment in the asymptomatic patient is recommended to prevent this catastrophic occurrence.

Endotoxin-induced tumor necrosis factor.

The serum of BCG-infected mice treated with endotoxin contains a substance (tumor necrosis factor, TNF) which mimics the tumor-necrotizing action of endotoxin itself. TNF is not residual endotoxin, but a factor released from host cells, probably macrophages. TNF induced in the same way in rats and rabbits also causes necrosis of transplanted murine tumors. Unlike endotoxin, TNF is toxic in vitro for neoplastic murine and human cell lines but not for mouse embryo culture. TNF has striking effects on immunologic reactions in vitro, some like those of endotoxin and others unlike those of endotoxin. TNF is a glycoprotein; its molecular weight is less than 70,000. Highly purified preparations do not contain lysosomal or nonlysosomal serum enzymes, interferon or prostaglandin E1.

The psychological and social effects of myocardial infarction on wives.

Eighty-two wives of men suffering a first myocardial infarction were interviewed while their husbands were in hospital, and again two months and a year after they went home. The wives had substantial and persistent psychological symptoms, and the husbands' illness had continuing effects on their work, leisure and social activities, and family life and marriage, their psychosocial disability being comparable to that of the patients. Measures of psychosocial adjustment before the illness and the quality of the marriage and of family life were good predictors of outcome for the wives. The women had a major role in the patients' readjustment during convalescence, and their attitudes and behaviour as well as the general quality of family life were important determinants of the rate and extent of the patients' recovery. The wives of patients with myocardial infarction should have more practical help and advice during the hospital period, and the whole family should be given advice and help throughout the convalescence.

Diagnosis and evaluation of retroperitoneal tumors by computed tomography.

Nineteen patients with primary and recurrent retroperitoneal tumors were examined by computed tomography. Correlation between CT and subsequent operative findings was remarkably accurate. CT provided clinically useful information regarding the presence, size, extent, and composition of the tumors and also their effect on adjacent structures. CT is recommended for any patient suspected to have a primary or recurrent retroperitoneal tumor.

Computed tomography of the retroperitoneal space.

Computed body tomography is an easily accomplished method that precisely displays the normal and pathologic anatomy of the retroperitoneal space. Suspected retroperitoneal disorders, which are often clinically confusing or obscure, can now be detected or excluded with remarkable accuracy. Few innovations in radiology have more effectively fulfilled such a conspicuous need.

Attitudes and advice after myocardial infarction.

While medical opinion increasingly favours an active approach to rehabilitation after myocardial infarction, interviews with 40 patients and their relatives showed a low degree of understanding of medical advice and information. There was general satisfaction with treatment, but communication was seen as often being inadequate, vague, and conflicting.

Urinary tract tomography.

The application of the priniciples of linear tomography to enhance the visualization of the kidneys during excretory urography represents a major advancement in the quality of excretory urography. The ability to visualize the renal parenchyma and renal outlines on tomograms has resulted in a significant increase in the detection of renal masses, parenchymal scars, and adrenal tumors. The use of tomography may also contribute significantly to the evaluation of patients with various other urinary tract diseases. It has been our practice during the past 5 years to obtain linear tomograms as a routine procedure during excretory urography in all adults and in selected pediatric patients. We believe that tomograms of the kidneys represent an important part of the excretory urogram and should be done as a routine procedure.
