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.

Introduction: The elements and perception of beauty vary between populations around the world. To obtain better results, surgical techniques should be planned based on anthropometric characteristics of the race, location, and body mass index (BMI). Objectives: To determine which are the standard measurements and anatomical proportions of the breast in a healthy Mexican women population. Materials and Methods: Female Mexican volunteers between 20 and 60 years of age, without any history of breast illness or breast surgery were studied. Demographic information and standard breast anthropometric measurements were collected manually by one of the authors. For the statistical analysis a Student-T test was performed, and the Pearson correlation coefficient was obtained using the latest version of SPSS software. Results: 78 volunteers were included in the analysis. Mean height, weight and BMI were 1.6 m, 68.9 Kg, and 26.6 Kg/m2 respectively. The mean anthropometric values found were: Supra Sternal notch to nipple distance (SSN:N) 22 cm, Breast volume (BV) 372.6 cm3, Upper breast pole length (UBPL) 11 cm, Lower Breast Pole length (LBPL) 7.7 cm, Midline to Nipple distance (ML:N) 10.2 cm, Transverse diameter of the Nipple areola complex (NAC-T) 4.1 cm, Height of the Nipple Areola Complex (NAC-H) 4.1 cm, Base of the breast (BB) 13.4 cm, Upper Pole to Lower Pole Ratio (UPP:LPP) 58.9:41.1. A statistically significant difference between Right and left breast was not found. The UPP/ LPP ratio in our population is far different from what is considered internationally aesthetic (45:55). A positive correlation was found between weight/ BMI and SSN:N, BV, BB, ML:N and LBPL. Also between age and SSN:N, LBPL, BV and BB. Conclusion: This study sets the Anthropometric grounds in Mexican population for an objective individual patient analysis and comparison with the female population of this and other nations.

Introduction: Breast cancer is the most common cancer in women worldwide, representing a major public health problem. There is still little information comparing the satisfaction of the patients who finished their process against the ones who start it but did not finish it. The aim of our retrospective study was to analyze the results in terms of satisfaction after one year of undergoing to complete breast reconstruction (CBR) vs incomplete breast reconstruction (IBR). Materials and Methods: Retrospective study of patients that underwent breast reconstruction (BR) surgery after mastectomy for breast cancer treatment. Performed at Hospital Central Sur de Alta Especialidad PEMEX in Mexico City, including patients from January 1, 2015 to January 01, 2020. Demographic baseline variables were included. BREAST-Q satisfaction questionnaires one year after the last reconstructive procedure were analyzed. Results: A total of 44 patients fulfilled the inclusion criteria. Of these 44 patients, 11 were included in the IBR group, and 33 patients in the CBR group. There were no statistically significant differences between the two groups in terms of age (IBR 56.09 vs CBR 53.06 years, p = 0.321);BMI (IBR 27.94 vs CBR 26.40, p = 0.253), time from mastectomy to first reconstructive procedure (IBR 22.8 vs CBR 31 months, p = 0.957), history of chemotherapy (IBR 27.3% vs CBR 33.3%, p = 0.709) and radiotherapy (IBR 54.5% vs CBR 42.4%, p = 0.484), additionally type of reconstruction, affected side or complication rate were not significantly different. Regarding postoperative satisfaction, only the second module of satisfaction with breasts displayed statistically significant differences, with a higher score in the CBR group (46.27 vs 52.27, p = 0.019). Other items explored didn’t show significant differences. Discussion: The data reported in this study suggest that regardless of whether the last stage of a BR is reached, the results in these settings can be very similar in terms of psych

作者： alfredo chama naranjo Cuahutémoc Márquez Espriella Alberto Ignacio Cahuana Quispe Barbosa Villarreal Fernando Ana Priscila Campollo López Mauricio Gutiérrez Álvarez Carlos Emiliano García Córdova Jesús Ricardo García Corral Cuervo Vergara Marco Antonio Jorge Luis Rosales Becerra Dávila Díaz Rodrigo Edgar Alan Guillen Martínez Marín Canto Miguel Eduardo Luis Arturo Herrera Lozano Ochoa Contreras Erick Cesar Martinez Villalobos Claudia Nallely Cruz Soto Randall Camacho Rodriguez Hayah Ricardo Alberto Pulido López Edwing Michel Jaimes Durán Department of Plastic and Restrictive Surgery Hospital Central Sur de Alta Especialidad Pemex Mexico City Mexico

Background: In clinical practice, acute and chronic wounds continue to be a challenge. Unfortunately, wound care is often inadequate or inappropriate. The implementation of wound clinics involving an interdisciplinary team for wound care and treatment yields favorable clinical outcomes as well as a reduction in economic expenses due to a higher rate of healing, a decrease in hospital stays, and a reduction in the number of readmissions. The establishment of wound clinics enhances the utilization of diagnostic, preventive, and therapeutic resources, improving the quality of life of patients and facilitating their reintegration into their normal lives. The objective is solely to describe the importance of wound clinics in the medical profession. Methods: A retrospective literature search was conducted to include articles no more than 10 years old that reported measures or results of the study in order to perform a literature review and describe the importance of wound clinics in medical practice. Results: A total of 7 articles were obtained with the inclusion criteria, the most recent being from the year 2023 and the oldest from 2013. Conclusion: An important area for improvement in the healthcare industry is the management and treatment of complex wounds. The establishment of wound clinics offers comprehensive and specialized care for both acute and chronic complex wounds with the goal of enhancing secondary illness patients’ prevention, treatment, and rehabilitation.

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.

Background: The trigger finger, also known as stenosing tenosynovitis of the flexor tendon, is a common cause of hand disability;This can result in significant limitations in certain daily living activities. It is possible to treat this condition with conservative or surgical methods. Methods: This is a retrospective, observational, cross-sectional and descriptive study. The source population consisted of all patients with a diagnosis of trigger finger who had been treated in the department of plastic and reconstructive surgery of our institution between 2020 and 2023. The primary objective of this study is to determine the prevalence and characterize the clinical and surgical characteristics of the population affected by trigger finger in our hospital. Results: The total population was 237 patients, of which 165 were women (70%) and 72 men (30%). The most affected hand was the right hand, with a total of 158 patients (67%). In the right hand, the middle finger was the most affected (45%). Of the 237 patients, 80 of them had obesity (34%), 86 had type 2 diabetes mellitus (36%), 95 had systemic arterial hypertension (40%). Open technique was performed in 190 (80%) patients, while percutaneous technique was performed in 47 (20%) of them. Conclusion: The female sex was twice as frequent, and the middle finger and thumb were the most affected. Most of the patients received surgical treatment with open approach and percutaneous approach in 20% of them.

Ligand effects on the structure and vibrational properties of the thiolated Au18 cluster

引用

Progress in Natural Science:Materials International 2016年第5期26卷 510-515页

作者： alfredo Tlahuice-Flores CICFIM-Facultad de Ciencias Físico-Matemáticas Universidad Autónoma de Nuevo León

Most of the studies devoted to thiolated gold clusters suppose that their core and Au-S framework do not suffer from distortion independently of the protecting ligands（-SR） and it is assumed as correct to simplify the ligand as SCH3. In this work is delivered a systematic study of the structure and vibrational properties（IR and Raman）of the Au18（SR）14cluster. The pursued goal is to understand the dependency of the displayed vibrational properties of the thiolated Au18cluster with the ligands type. A set of six ligands was considered during calculations of the vibrational properties based on density functional theory（DFT） and in its dispersioncorrected approach（DFT-D）.
