Biofilm delays wound healing: A review of the evidence

Biofilm is the predominant mode of life for bacteria and today it is implicated in numerous human diseases. A growing body of scientific and clinical evidence now exists regarding the presence of biofilm in wounds. This review summarizes the clinical experiences and in vivo evidence that implicate biofilm in delayed wound healing. The various mechanisms by which biofilm may impede healing are highlighted, including impaired epithelialization and granulation tissue formation, and reduced susceptibilities to antimicrobial agents and host defenses. Strategies to manage biofilm and encourage progression to wound healing are discussed;these include debridement and appropriate antimicrobial therapies which may be improved upon in the future with the emergence of anti-biofilm technologies.

Minimally invasive treatment of forearm double fracture in adult using Acumed forearm intramedullary nail: A case report

BACKGROUND Currently,open reduction internal fixation is the conventional surgical method for treatment of double ulna and radius fracture.However,open reduction is associated with a high risk of complications.This case of forearm double fracture involved a patient treated using an Acumed intramedullary nail.The patient experienced good follow-up outcomes.The Acumed forearm intramedullary nail enables early functional exercise and hastens healing of the fracture.Few studies have reported on the use of this approach for the treatment of fractures.CASE SUMMARY A 23-year-old male patient was admitted to hospital after 5 h of pain,swelling,and limited activity of left forearm caused by a careless fall.Physical examination showed stable basic vital signs,swelling of the left forearm,and severe pain when pressing on the injured part of the forearm.Further,friction was felt at the broken end of the bone;the skin was not punctured.Movement of the left hand was normal,and the left radial artery pulse was normal.Three-dimensional computed tomography examination showed an ulna fracture of the left forearm and comminuted fracture of the radius.The fracture was located in the upper third of the radius,with significant displacement on the fracture side.Clinical diagnosis further confirmed the left radius comminuted fracture and ulna fracture.After analyzing the fracture pattern,age,and other patient characteristics,we chose an Acumed nail for treatment and achieved good follow-up outcomes.CONCLUSION Acumed forearm intramedullary nail for fixation of ulna and radius fracture reduced complication risk and resulted in good follow-up outcomes.

Breast Reduction Complications

Background: Breast reduction surgery is increasing in popularity, with so many techniques all around the world, and the community’s knowledge of the details of this procedure increases thanks to the Internet and easy access to information, which increases breast reduction reviews for plastic surgery clinics. Reduction mammaplasty is an established and effective technique to treat symptomatic macromastia. Variable rates of complications have been reported, and there is a continued need for better outcome assessment studies. Aim: The purpose of this study was to identify the complications occurred during the first year of breast reduction surgery. Materials and Methods: A prospective study over a 1-year period from October 2018 to October 2019, that included 32 patients who underwent breast reduction surgery using the same technique (inferior pedicle and inverted T scar) in the Department of Plastic Surgery at Al-Mouassat University Hospital, Damascus, Syria. Patients were followed through a whole year after surgery and complications that occurred were recorded. Results: Complications that occurred in 14 patients (43%), and, and were more common in patients with larger breasts and worse symptoms before surgery. The most common complication was delayed wound healing, and it was associated with breast volume before surgery and with smoking. In general, the most relevant factor influencing the incidence of complications was the weight of the resected breast tissue, which is mainly related to the size of the breast before surgery. Conclusion: The weight of the resected breast tissue was the most important factor influencing the occurrence of complications after breast reduction surgery. The most prevalent complication was delayed wound healing and it was associated with the weight of the removed tissue.
