Alkaline reflux gastritis associated with abnormalities of the gastrojejunostomy.
Alkaline reflux gastritis is presently accepted as being part of the postgastrectomy syndrome complex. Our experience with this entity has revealed a frequent association of alkaline reflux gastritis with functional or organic abnormalities of the gastric remnant and/or newly formed gastrojejunostomy. The role alkaline reflux gastritis plays as a separate entity in the symptomatic patient remains to be clinically determined.

Amputations in peripheral vascular occlusive disease.
One hundred consecutive patients undergoing major lower extremity amputations were critically analyzed over a five year period. The results of surgical care and the degree of success of rehabilitation were determined. The number of patients with peripheral vascular occlusive disease who require major lower extremity amputations appears to be increasing and they continue to present a challenge to the surgeon.

Volvulus of the sigmoid colon: a ten-year study.
A ten-year study of volvulus of the sigmoid colon is presented. Although the results of treatment of volvulus of the sigmoid colon are generally improving, the challenge for further improvement remains.
Alkaline reflux gastritis. A study in forty postoperative duodenal ulcer patients.
A study to determine the incidence of alkaline reflux gastritis in forty postoperative duodenal ulcer patients has been presented. Since the majority of patients had evidence of gastritis, the precise role that gastritis plays in the production of symptoms is discussed but needs further clarification. It is suggested that the presence of gastritis may only represent an incidental or associated finding in many patients presenting with symptoms presumably characteristics of alkaline reflux gastritis.
Cancer of the esophagus: ten-year experience.
A critical analysis of 52 patients with cancer of the esophagus indicates the continuing challenge that this disease entity presents to the surgeon and radiotherapist. Difficulty of cure or palliation is further compounded by the many significant associated medical problems found in certain patient populations, such as that characteristic of our VA Hospital. Although cure is a rarity in cancer of the esophagus, continued palliative efforts must be exerted for these otherwise hopeless patients.

Lumbar sympathectomy in the treatment of uncomplicated intermittent claudication.
The precise role lumbar sympathectomy plays in the treatment of uncomplicated intermittent claudication continues to be debated. Past experience at this institution indicates that lumbar sympathectomy has a definite positive role in uncomplicated intermittent claudication. A critical analysis of the 86 patients included in this study adds further support to this contention. Properly selected patients who undergo complete anatomic sympathetic denervation of the lower limbs continue to have very satisfactory results, as they have since 1947 in this institution.
Lumbar sympathectomy in the treatment of peripheral vascular occlusive disease. Ten year study.
A study of the results of lumbar sympathectomy in the treatment of peripheral vascular occlusive disease has been presented. Results continue to be encouraging in properly selected patients, as they have been since 1947.
Quantitation of human peripheral blood T and B lymphocytes.
Centrifugation of heparinized peripheral blood on Ficoll-Hypaque under defined conditions is a most common method of lymphocyte purification in clinical studies. A loss of 25-30% of lymphocytes may occur during this procedure due to incomplete recovery of lymphocytes from the plasma layer after the gradient centrifugation and/or to poor recovery during the washing process. The loss is not selective since T and B cells are lost in the same proportions as determied by several different methods for T and B cell identification. Quantitation of T and B lymphocytes in terms of total number/mm-3 of peripheral blood is necessary in order to determine deficiencies in either of these two cell populations. The percentage values are inadequate in clinical evaluations. Thus, patients with chronic lymphocytic leukemia show elevated absolute number of T cells absolute numbers of T and B cells as well as percentages ought to be reported in all clinical studies.
