PURPOSE To compare two sling designs (single loop or double pentagon) and a variety of suture material that was used in frontalis suspension surgery for correction of upper eyelid ptosis. DESIGN Retrospective, nonrandomized, comparative interventional case series. METHODS Medical record review of 99 patients (164 surgeries) who underwent frontalis suspension surgery for upper eyelid ptosis ...

PURPOSE Patients with cryptorchidism can have such short spermatic vessels that it is impossible to place the testicle in a satisfactory scrotal position using conventional orchiopexy. In these cases the most commonly used operation is 1 to 2-stage Fowler-Stephens orchiopexy. We present our surgical experience using staged inguinal orchiopexy without section of the spermatic vessels in patients...

PURPOSE Analyze the morphological and structural outcomes of a patch of expanded polytetrafluoroethylene in the treatment of an iatrogenic injury of the common bile duct. METHODS In Group 1 (Sham), 7 dogs underwent 3 laparotomies with intervals of 30 days between them. In Group 2, 10 dogs underwent transient common bile duct obstruction. After 30 days, this biliary occlusion was undone and a ...

In this paper we describe a newly developed maskless projection system for lithography based on a digital mirror device and its use for the rapid creation of microfluidic structures in a polytetrafluoroethylene (PTFE) like highly fluorinated monomer.

This paper reports a comprehensive laboratory study into the thermophysical, physical-mechanical characteristics, and tribological properties of designed composite materials based on polytetrafluoroethylene. In structures machines mechanisms, significant role belongs to conjugations made from polymeric polymer-composite materials. The reliability machines, in general, depends large extent movab...

OBJECTIVE The aim of this study was to compare the results of application of 2 types of superelastic nitinol prostheses. STUDY DESIGN Temporal bones study with planned data collection. SETTING Tertiary referral center. SUBJECTS AND METHODS Malleostapedotomy was performed in 15 human temporal bones implanting 3 different prostheses: manually crimping polytetrafluoroethylene (MC-PTFE) pisto...

Patients surviving a first episode of variceal bleeding have a risk of over 60% of experiencing recurrent haemorrhages within 1 year from the index episode. Because of this, all patients surviving a variceal bleeding should receive active treatments for the prevention of rebleeding. beta-Blockers+/-isosorbide-5-mononitrate and band ligation are effective in preventing recurrent bleeding and bot...
