The subject of this paper is a study designed to compare power-assisted lipoplasty (PAL) to traditional lipoplasty (TL) in 30 patients. PAL was used on one side and TL was used on the matching contralateral body area. In PAL, a cannula powered by medical-grade nitrogen (N(2)) reciprocates between 2000 and 4000 cpm with a 2-mm stroke. The device is commercially offered by MicroAire Surgical Instruments. While there was no difference in the speed of recovery or in the aesthetic quality of the result between the two sides, PAL was found considerably superior as far as ease of fat extraction.
Residents of a long-stay geriatric ward at the University Hospital Basel were included in a study to investigate the effects of hypovitaminosis D and immobility. All 91 women (mean age 82.5 years) and 92 men (mean age 78.7 years) were enrolled in the study. Measurements included bone resorption, as measured by urinary deoxypyridinoline (dpd), serum 25-hydroxyvitamin D (25OHD), serum intact parathyroid hormone (iPTH), and their correlations with a four grade mobility score. Mobility score reflected the degree of weight bearing, ranging from walking independently to primarily bed bound. In 86% of all residents, serum 25OHD levels were below the normal limit of 12 ng/ml. Secondary hyperparathyroidism (HPT) was detected in 24% of all patients, using 55 pg/ml as the upper limit for serum iPTH. No significant correlation was found between urinary dpd and serum 25OHD or serum iPTH. Mobility index and both urinary dpd (f: P = 0.001, r = 0.37; m: P < 0.0001, r = 0.47) and serum calcium (female: P = 0.007, r = 0.28; male: P = 0.02, r = 0.24) were positively related. In institutionalized elderly people with a high prevalence of vitamin D deficiency serum intact PTH levels did not correlate with bone resorption as measured by urinary deoxypyridinolin. However, more immobile subjects had significantly higher excretion rates for urinary dpd and higher serum calcium levels. Our results suggest that in elderly people immobility may contribute to bone loss that might preempt the development of secondary HPT through elevation of serum calcium.
Even in the case of palmar soft-tissue defects due to infections, the expanded DMCA flap may be a valuable option for coverage. It may be possible to localise the dorsal metacarpal arteries by ultrasonic Doppler probe in a smoking patient after a period time of nicotine abstinence, if initial attempts at detection fail. If the perfusion of the rotated extended DMCA flap appears to be compromised, we recommend the repositioning of the flap. Its transposition may be safely performed after a preconditioning period.
The author discusses how wide experience with lipoplasty techniques, the development of modified brachioplasty procedures, and improved understanding of skin retraction have reduced surgeon discomfort about brachial lipoplasty and brachioplasty.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
