Morphological and Histological Changes Following Triamcinolone Injection Alone or Mixed Injection of Triamcinolone and Botulinum Toxin in Upper Eyelid.

Objective: The purpose of this experiment was to evaluate the functional and histologic changes in the upper eyelid muscles after injection of triamcinolone acetonide (TA) alone or TA combined with botulinum toxin A (Botox or BTXA) in the cynomolgus monkey model.

Methods: Twenty eyes of 10 cynomolgus monkeys were divided into 4 groups: 3 experimental groups (1, 2, and 3) and the control group (group 4) based on the injection type. In group 1, 0.

Data-driven Identification of Parametric Governing Equations of Dynamical Systems Using the Signed Cumulative Distribution Transform.

This paper presents a novel data-driven approach to identify partial differential equation (PDE) parameters of a dynamical system. Specifically, we adopt a mathematical "transport" model for the solution of the dynamical system at specific spatial locations that allows us to accurately estimate the model parameters, including those associated with structural damage. This is accomplished by means of a newly-developed mathematical transform, the signed cumulative distribution transform (SCDT), which is shown to convert the general nonlinear parameter estimation problem into a simple linear regression.

Effect of a Team Approach to Pressure Injury Management over 5 Years in a Tertiary Hospital.

Objective: The authors' facility established a novel integrated wound care team (IWCT), which included the implementation of a strict treatment algorithm by the patients' attending providers and a specialized wound care team led by a plastic surgeon. Investigators then retrospectively analyzed clinical outcomes of pressure injury (PI) management by the IWCT over 5 years.

Methods: The authors performed a retrospective chart review and periodic statistical analysis of the data for all patients with PI referred to the IWCT in the authors' center from May 2015 to April 2019.

Impact of perioperative vasopressors on lower extremity free flap reconstruction.

Purpose: Free tissue transfer is a treatment option for soft tissue defects of the lower extremity. For a successful outcome, it is necessary to evaluate the vessel condition and blood flow patency. The administration of a vasopressor could impact the survival rate of free tissue transfer; however, there is a lack of studies on vasopressor use and lower extremity reconstruction.

Factors affecting the outcome of lower extremity osteomyelitis treated with microvascular free flaps: an analysis of 65 patients.

Background: Free flaps have been a useful modality in the management of lower extremity osteomyelitis particularly in limb salvage. This study aimed to determine the factors affecting the outcome of free flap reconstruction in the treatment of osteomyelitis.

Methods: This retrospective study assessed 65 osteomyelitis patients treated with free flap transfer from 2015 to 2020.

Early mobilization vs delayed mobilisation following the use of a volar locking plate with non-vascularized bone graft in scaphoid non-union. A multicentred randomised controlled-trial.

Purpose: This randomized clinical trial investigated the potential for early mobilization of the wrist following open reduction and internal fixation (ORIF) with a scaphoid specific volar locking plate and non-vascularized bone graft for scaphoid non-union.

Methods: 16 patients with scaphoid non-union underwent internal fixation with a scaphoid-specific volar locking plate and iliac crest bone graft and were randomized to one of two treatment arms (A) The control were immobilized in a below elbow cast for 6 weeks (n = 9) and (B) The experimental arm were mobilized early with a removable wrist splint (n = 7). Outcomes were measured preoperatively, and at 3 months post operatively.

What is the impact of infrapopliteal endovascular intervention on free flap survival in diabetic foot reconstruction?

Background: The combination of endovascular intervention and microvascular free flap transfer has been effectively used for chronic ischemic wounds of lower limb. The aim of this study was to determine the influence of angioplasty on free flap survival in diabetic foot ulcer reconstruction.

Methods: A retrospective research was conducted for 46 diabetic patients with chronic ulcer of the foot.

Scaphoid specific volar locking plate and non-vascularised iliac crest bone graft in scaphoid non-union. A comparative cohort study.

Scaphoid non-union develops in 10% of scaphoid fractures. There is sparse literature on fixation methods other than screws. We compared union rates following fixation of scaphoid non-union using screw fixation and a novel method of plate fixation.

Filter Design and Performance Evaluation for Fingerprint Image Segmentation.

Fingerprint recognition plays an important role in many commercial applications and is used by millions of people every day, e.g. for unlocking mobile phones.

Outcome of surgical management of bony metastases to the humerus and shoulder girdle: a retrospective analysis of 93 patients.

Background: Metastatic disease to the shoulder girdle is a challenging problem because of the potential for pain, pathologic fracture and loss of function of that limb. Management of the bone disease centers around palliation, prevention of further complications and the preservation of residual function. A variety of surgical options exist for managing metastatic disease to the shoulder girdle and our experience with over 90 patients is reported.
