Experience in the use of the CO2 laser beam in complex surgical debridement of primary traumatic wounds in 77 children showed that in a power density range of 15 to the Wt/cm2 it led to a sharp decrease of microbial dissemination in the wound and in 81.3% of cases to sterility of the wound surface. Carbon-dioxide laser radiation has an effect on the surface leucocytic-necrotic layer, replacing it with a narrow zone of thermal coagulation necrosis, and on the polymorphonuclear leucocytes lying in the thickness of the tissue of the wound wall at different depths. As compared to the control group of patients (86 children with 91 wounds), the incidence of suppurations reduced from 14.2 to 2.6%.

Lisfranc Fracture-dislocation With Extensor Hallucis Brevis Tendon Interposition: A Case Report.
JBJS Case Connect
January 2025
Department of Orthopaedic Surgery, Nemours Children's Health, Wilmington, Delaware.
Case: A 14-year-old adolescent girl sustained a Lisfranc fracture-dislocation with an interposed extensor hallucis brevis (EHB) tendon. Following multiple failed attempts at closed reduction in both the emergency department and the operating room, the patient was treated in a staged manner with temporizing closed reduction and percutaneous pinning in improved alignment, followed by definitive open reduction and internal fixation once soft tissues allowed.
Conclusions: Anatomic reduction and stable fixation of Lisfranc injuries is vital to regain stability and reduce the risk of midfoot arthritis and collapse.
Surgical Site Infection after Craniotomy in Neuro-Oncology (SINO): A protocol for an international prospective multicentre service evaluation across the United Kingdom and Ireland.

Introduction: Given its proximity to the central nervous system, surgical site infections (SSIs) after craniotomy (SSI-CRAN) represent a serious adverse event. SSI-CRAN are associated with substantial patient morbidity and mortality. Despite the recognition of SSI in other surgical fields, there is a paucity of evidence in the neurosurgical literature devoted to skin closure, specifically in patients with brain tumors.

Circulating monocytes contribute to the defense against pathogens and play a crucial role in maintaining immune homeostasis. While there is substantial evidence regarding the triggers of monocyte activation, our understanding of how monocyte function is restored toward homeostasis after activation remains limited. Here, we assessed the changes in monocyte anisocytosis upon activation in blood, measured by monocyte distribution width (MDW), a biomarker for sepsis.

Department of Ophthalmology, Ege University Medical Faculty Hospital, Ege University, 35100, Bornova, Izmir, Turkey.
Purpose: To evaluate the severity distribution of chemical burn-induced Limbal stem cell deficiency (LSCD) according to the novel global consensus classification and to compare the treatment approach, before and after the global consensus.
Methods: Medical records of 127 eyes of 109 patients with LSCD were included. LSCD stages were categorized according to the global consensus classification published by "International LSCD Working Group".

envenomings are a public health problem in West Africa, leading to bleeding and hypocoagulability. The aim of this study was to assess the hemostasis disorders associated with envenoming. Envenomed patients with an abnormal whole blood clotting test (WBCT) were prospectively included at Tanguiéta, Benin.
