A review of 685 rhytidectomies: a new method of analysis based on digitally processed photographs with computer-processed data.

It is the aim of this work to present a simple method to assess the surgery used for facial aging (face-neck lift), based on a digital computerized analysis of images, and to include an evaluation of the results obtained from its use on 685 cases of face lift, which our team resolved from January of 1990 to December of 1997. To this end, we reviewed 4110 preoperative and postoperative slides of these patients and processed them using a computer, obtaining the results presented herein. It is worthy of note that in this new method of analysis that we have used, data, measurements, or aspects of facial aging have revealed the most homogeneity and reliability when comparing the results obtained with the reality observed by both the surgeon and the patient. Likewise, we rejected other analyzed data, as they gave different or unreal results when compared with the reality.

Variations of plasma immunoreactive motilin, pancreatic polypeptide, gastrin and somatostatin along the duodenal motility cycle in the pig.

The peripheral plasma concentrations of immunoreactive motilin, pancreatic polypeptide (PP), somatostatin and gastrin were measured in 7 pigs fasted to 24 h and subsequently fed a standard meal. Plasma motilin peaked during the last part of phase II activity of the migrating myoelectric complex (MMC) sequence (25.2 +/- 2.3 pM), the lowest value being recorded during phase I (10.6 +/- 1.5 pM) after a 24 h fast. Plasma motilin remained at a low level during the digestive pattern of duodenal activity, no fluctuation occurring when the first postprandial MMC recurred. At variance analysis, gastrin and PP were not released phasically with MMC in the fasting state, while at autocovariance both peptides tended to fluctuate during the MMC sequence with positive and negative peaks at regular intervals along MMC cycles. No variation of plasma somatostatin was observed in the fasting animals. These findings argue against a major role of circulating PP, gastrin and somatostatin-like components in the control of fasted and post absorptive duodenal motility in pigs while the role of motilin remains equivocal.

Echocardiographic changes after successful renal transplantation in young nondiabetic patients.

Eighteen young nondiabetic patients with chronic renal failure were studied by M-mode echocardiography before and three to 67 weeks after a successful renal transplant. Left ventricular mass (LVM), cardiac output (CO), and stroke work, which were increased before the operation, decreased afterward, in some cases to normal values. Both regression of the LVM and normalization of CO were detected as early as three weeks postoperatively and probably resulted from changes in the end-diastolic volume, mean systemic blood pressure, and hematocrit as a consequence of normal renal function. Because all the patients had normal left ventricular function and only moderate dilatation of the left ventricle, it is not known whether these striking beneficial changes after SRT also will occur in patients with significant dilatation or dysfunction of the left ventricle.
