Squamous-cell carcinoma arising in a lateral periodontal cyst.

A rare case of well-differentiated squamous-cell carcinoma arising in the epithelial lining of a lateral periodontal cyst is reported. Submission of surgically removed tissues for histopathologic evaluation is emphasized. The surgical site has been reconstructed and functions well.

Aggressive ossifying fibroma of the maxilla: review of the literature and report of case.

A case of a large aggressive ossifying fibroma of the maxilla has been presented. Review of the literature shows the literature shows the difficulty in establishing a definitive diagnosis through any single diagnostic modality. Much of this is due to the confusion surrounding classification of the tumor.

Effect of aspirin and acid on human jejunal mucosa. An ultrastructural study.

To determine the effects of aspirin and hydrochloric acid on human jejunal mucosa, three obese patients with a small intestinal bypass that opened on the abdominal wall as a mucous fistula were studied. An 80-mM solution of HCl, a 40-mM suspension of aspirin (equivalent to two tablets in a glass of water), and a combination suspension of 40 mM aspirin plus 40 mM HCl damaged a mean +/- SE of 26 +/- 13% (P less than 0.05), 24 +/- 5% (P less than 0.

All pustular nodules are not bacterial.

A case of lymphocutaneous sporotrichosis was thought to represent bacterial pyoderma. Lack of recognition led to excessive costs and a delay in the institution of specific therapy. The differential and an approach to diagnosis of pus-containing nodules are discussed.

The role of free fatty acids in the regulation of lipolysis by human adipose tissue cells.

The effect of added fatty acid on lipolysis and cyclic AMP concentration of human adipose tissue cells was studied. The addition of sodium oleate decreased the lipolytic response of adipocytes to 10(-7) M isoproterenol. Inhibition was detectable with the lowest quantity of oleate added, 0.

In-vitro observations on isolated adipose tissue cells from hyperobese subjects.

Isolated adipose tissue cells were prepared from subcutaneous samples obtained from nine morbidly obese subjects weighing from 187 to 306% of ideal body weight. The responsiveness of these adipocytes to a number of test substances was determined by measuring cellular cyclic AMP concentration at one-half hour and glycerol release at four hours. Theophylline (10(-3) M) and epinephrine (10(-5) M) stimulated lipolysis; theophylline stimulated an increase in cyclic AMP, while epinephrine failed to prompt a significant change in the nucleotide.

Arteriovenous malformation of the mandible: report of case.

A case of a potentially lethal arteriovenous malformation of the right side of the mandible has been presented. Procedures that may be helpful in diagnosing the lesion have been discussed, and a protocol for treatment of these lesions in the mandible has been proposed. Research of the cause and management of these lesions is greatly needed.

Unilateral relapse after oblique osteotomy of the mandibular rami: report of case.

A case of unilateral relapse of mandibular prognathism after oblique osteotomy of the mandibular rami is described. A brief review of the pertinent literature is presented and a method of intraosseous fixation by Vitallium plating is illustrated. The need for close postoperative observations and reinstitution of active therapy at the first sign of a relapse tendency is emphasized.

Some nutrient interrelations during total intravenous alimentation in adult man--a review.

Selected aspects of total parenteral nutrition in man are reviewed with emphasis on carbohydrate, lipid, and hormonal interactions. In an experiment to test for the essentiality of a specific amino acid, a normal adult man received all major and minor nutrients, except lipids, by intravenous alimentation for 48 days. A chemical deficiency of essential fatty acids without clinical symptoms was promptly observed in four plasma lipid fractions and the phospholipid fraction of erythrocytes.

Blood loss and hypotensive anesthesia in oral-facial corrective surgery.

To evaluate accurately changes in blood volume during oral-facial corrective surgery, double-tagged radioisotope blood volume studies were performed preoperatively and postoperatively. Unexpectedly large RCV deficits that were not consistent with EBL were observed in studies conducted at two separate facilities. Hypotensive general anesthesia was used for the intended purpose of reducing blood loss in oral-facial corrective surgery.

Long term ridge augmentation with rib graft.

Results of ten cases are reported to indicate the bone augmentation that may be expected in three to six years using transoral rib grafting. Some augmentation was present in all cases. This is an improvement over the continued resorption that would have taken place in these already thin mandibles.
