Introduction: The standard treatment for complex wound care is autografting. The advent of dermal substitutes has provided a novel tool for the preparation of the bed to be grafted. However, most types of dermal matrices require the application of a skin graft a second time. Currently, other strategies have been developed to improve the vascularization process, such as negative pressure wound therapy (NPWT), which has been reported to reduce the time required for vascular growth and dermal matrix integration and thus achieve a shorter waiting period for autologous graft application. The present study aims to evaluate the effectiveness and safety of dermal matrix management associated with NPWT in the treatment of complex wounds. Methods: Seven patients with a diagnosis of complex wounds were enrolled in this study between July 1, 2015, and June 31, 2016. After debridement and having an adequate wound bed, patients who met the criteria for the application of combined therapy were treated with dermal substitutes and a negative pressure system. The percentage of graft integration into the wound bed, complications, length of hospital stay, and duration of therapy were analyzed. Results: The mean age was 42.5 ± 16 (39 - 54) years old;three women and four men were included in the study. The approximate size of skin loss was 120.7 ± 75 cm2 (25 - 250 cm2). The combined therapy of dermal matrix plus NPWT was instituted in all cases for a period of 14 days. There were no complications, with 100% graft integration in 6 of 7 cases. Patients were discharged after a mean hospital stay of 5.4 days. Conclusions: This study demonstrates that the utilization of combined dermal matrix plus NPWT therapy can be performed safely and effectively in patients with complex wounds with low complication rates and a short hospital stay.

Poland Syndrome: Breast Reconstruction Outcomes in 10 Years (2013-2023)

Summary: Poland syndrome is a rare congenital anomaly characterized by the partial or complete absence of the pectoralis major muscle and a wide spectrum of thoracic anomalies, predominantly on the ipsilateral side. These anomalies include hypoplasia or aplasia of the breast and its components, hypotrophy of subcutaneous fat, and absence of axillary hair, as well as hand deformities that can range from syndactyly to ectrodactyly. The aim of this study was to gather information about patients diagnosed with Poland syndrome at the Central South High Specialty Hospital of Petróleos Mexicanos over a period of 10 years and to identify their reconstructive algorithm. Materials and Methods: A retrospective, observational, and descriptive study was conducted to identify the population diagnosed with Poland syndrome at the “Central South High Specialty Hospital of Petróleos Mexicanos” during the period from 2013 to 2023. Results: The database of patients with Poland syndrome from 2013 to 2023 was analyzed, identifying a total of 8 patients with this diagnosis. Of these, 7 were women (90%) and 1 was a man (10%). The left side was more frequently affected (80%) compared to the right side (20%). The average reconstructive process required two surgical stages, mainly consisting of breast expander reconstruction (first stage) and replacement of the expander with an implant (second stage). Conclusions: Despite being a rare congenital condition, the volume of patients treated at the Central South High Specialty Hospital allows for improved diagnosis and contributes to their reconstructive process. The lack of diagnosis in the male population is notable, likely due to the absence of adequate screening.

Epidemiology of Fingertip Injuries at South Central Hospital Petróleos Mexicanos “Pemex” with a Review of the Literature

引用

Journal of Biosciences and Medicines 2023年第6期11卷 182-195页

作者： Fernando Barbosa-Villarreal Cuahutémoc Márquez-Espriella Erika Barlandas-Quintana Ana Priscila Campollo-López Mauricio Gutiérrez-Álvarez Carlos Emiliano García-Córdova Jesús Ricardo García-Corral Alfredo Chama-Naranjo Ricardo Alberto Pulido-López Patricia Llizette López-Medellín Edgar Alan Guillen-Martínez Jonathan Steve Rodríguez-Alaníz Edwing Michel Jaimes-Duran Carlos Manuel Cortes-Aguilar mauro garibaldi-bernot Omar Alberto Pérez-Benítez Miguel Eduardo Marín-Canto Luis Arturo Herrera-Lozano Héctor Manuel Suarez-Ortega Alejandro Cruz-Zarate Department of Plastic and Reconstructive Surgery Hospital Central Sur Petróleos Mexicanos Mexico City Mexico

Background: The hand is an essential component for performing our daily tasks;as a result, injuries to the fingertip are frequently seen. Accurate evaluation and treatment of fingertip injuries are essential to avoiding long-term disability, job loss and psychological issues. No matter the injury classification system, maintaining finger length, regaining sensation, and improving appearance are the three main objectives of treatment. The objective of this research was to outline the epidemiology of fingertip injuries treated between 2021 and 2022 at a highly specialized referral hospital in Mexico City. Methodology: This investigation is cross-sectional, retrospective, and observational. From January 2021 to December 2022, 60 patients with a diagnosis of fingertip injury from the South Central Hospital “Pemex” were included. The descriptive statistical analysis was performed using SPSS29. Results: 60 patients were included, 27 (45%) were women and 33 (55%) were men. Allen’s classification was able to classify only 19 patients, of which 18 (94.7%) had a type 1 classification and one (5.26%) had a type 2 classification. 10% of patients experienced complications, which included 2 patients with surgical site infections (3.3%), 3 patients with persistent pain (5%), and 1 patient (1.6%) with graft rejection. Conclusions: There are currently insufficient epidemiological data on hand and wrist injuries and its effects on labor in Mexico. Fingertip injuries require particular care in order to prevent complications and long-term damage. The creation of national registries could help with the creation of reference manuals for the care of hand and wrist injuries in our nation.
