Background: Alveolar periosteoplasty during primary repair of cleft lip is still a topic of debate due to the fear exacerbating maxillary retrusion. The authors present their experience with early closure of alveolar clefts. The study aims to analyze gingivoperiosteoplasty (GPP) by comparing the use of locoregional flaps versus distant grafts for reconstruction of the lower layer of the primary palate cleft.

Background: Only a few studies have directly compared outcomes of different arm contouring techniques across matched cohorts of patients. In this study, the authors present preliminary data comparing outcomes of conventional open suction-assisted brachioplasty (using the Pascal and Le Louarn procedure) versus combined liposuction/laser skin tightening in (grade 2b arm ptosis per El Khatib classification).

Methods: Thirty patients (60 arms) (28 women, two men) with moderate brachial ptosis (severe upper arm adiposity and a moderate degree of skin laxity) (grade 2b arm ptosis per El Khatib classification) were included.

Background: Drug penetration into the deeper arterial wall of heavily calcified lesions is one of the limitations of drug-coated balloons and drug-eluting stents in vascular interventions. The Temporary Spur Stent (TSS) system is characterized by a self-expanding nitinol stent that is uniformly covered in radialspikes, which, when coated, should allow a deeper penetration and longer retention of the drug into the diseased artery walls by penetrating through the calcified plaques.

Materials And Methods And Results: Uncoated TSS and paclitaxel (PTX)-coated TSS systems have been deployed in porcine peripheral arteries.

Aim: To compare Visian lens (model V4c) and Artiflex lens regarding quality (contrast sensitivity) and quantity (efficacy, predictability, safety and stability) of vision in correcting high myopia with recording and analysis of complications.

Methods: The comparative prospective study included 39 eyes of 23 patients with high myopia, 19 eyes had Visian lens implantation (model V4c) and 20 eyes had Artiflex lens implantation. The inclusion criteria were high myopia (higher than 6.

The present clinical trial was conducted to obtain additional data for the safety and efficacy of a head lice shampoo that is free of silicone compared with an anti-head lice product containing dimethicone. Both products act by a physical mode of action. This randomized, investigator-blinded, controlled clinical study was conducted between July and November 2016 in households of two villages (Abou Rawash and Shandalat) in Egypt.
