Development and validation of a newly developed nomogram for predicting the risk of deep vein thrombosis after surgery for lower limb fractures in elderly patients.

Background: Prevention of deep vein thrombosis (DVT) is indispensable in the treatment of lower limb fractures during the perioperative period. This study aimed to develop and validate a novel model for predicting the risk of DVT in elderly patients after orthopedic surgeries for lower limb fractures.

Methods: This observational study included 576 elderly patients with lower limb fractures who were surgically treated from January 2016 to December 2018.

[Treatment of type c fractures of the distal radius with volar locking compression plate and radial styloid process plate].

Objective: To analyze the effectiveness ofvolar locking compression plate (LCP) and radial styloid process plate for the treatment of type C fractures of the distal radius.

Methods: Between May 2010 and May 2011, 24 cases of type C fractures of the distal radius were treated, including 8 males and 16 females with an average age of 52 years (range, 23-73 years). Injury was caused by falling in 20 cases and by traffic accident in 4 cases.

A randomized trial to compare 24 h versus 12 h double dose regimen of levonorgestrel for emergency contraception.

Background: Levonorgestrel (0.75 mg given for two doses 12 h apart) has been proven to be an effective regimen for emergency contraception when the first dose is given within 72 h of unprotected coitus. However, the dosing interval is inconvenient for those taking the first dose in the afternoon.

Low dose mifepristone and two regimens of levonorgestrel for emergency contraception: a WHO multicentre randomised trial.

Background: A single 10 mg dose of mifepristone, and two 0.75 mg doses of levonorgestrel 12 h apart, are effective for emergency contraception. Because no studies had compared the efficacies of both compounds, or investigated a single dose of 1.
