Predictors of amputation in patients with diabetic foot ulcers: a multi-centre retrospective cohort study.

Purpose: Investigating risk factors for amputation in patients with diabetic foot ulcer (DFU) and developing a nomogram prediction model.

Methods: We gathered case data of DFU patients from five medical institutions in Anhui Province, China. Following eligibility criteria, a retrospective case-control study was performed on data from 526 patients.

Application of free serratus anterior muscle-fascial composite tissue flap and facial lipofilling in repairing progressive hemifacial atrophy.

Introduction: Progressive hemifacial atrophy (PHA) is a nonnegligible disease, and its treatment currently lacks consensus. We aim to conduct an analysis of PHA patients to summarize the postoperative effect. Moreover, we introduced the free serratus anterior muscle-fascial composite tissue flap as a safe and novelty surgical procedure for moderate-severe PHA.
