RESUMEN
INTRODUCTION: Lumbar puncture (LP) is a common invasive technique considered an essential learning milestone for anesthesiologists due to its application in spinal anesthesia. We aimed to develop an in-house LP simulator, test its effectiveness in learning the steps to perform an LP and analyze its impact on the first-year residents' self-confidence at our hospital. METHODS: We used 3D printing and silicone casting to create an LP simulator based on a lumbar spine computed tomography (CT). We divided 12 first-year anesthesiology residents into control and experimental groups. The control group received traditional training, while the experimental group practiced with the simulator for three months. We used a procedure checklist and a Likert scale survey to evaluate their procedural knowledge and self-confidence at baseline, three, and six months. Eighteen months later, we evaluated their LP performance skills. RESULTS: Both groups showed a significant improvement in their knowledge scores over time. After three months, the experimental group had a higher median knowledge score (10 (10 - 10) median (min-max)) than the control group (9 (8 - 9.5) median (min-max)) (p = 0.03). While there were no apparent differences in median self-confidence scores between the groups at any time point, the experimental group had a significant increase in their self-confidence for performing an unassisted LP, with a median score of 1/5 (1 - 2.3) at baseline and 5/5 (4.8 - 5) after six months (p = 0.006). In contrast, the control group's self-confidence scores decreased from 4/5 (3 - 4) after three months to 3/5 (2 - 5) after six months. The evaluation of performance skills did not yield statistically significant results. CONCLUSION: Our study demonstrates that an in-house LP simulator is an effective and practical approach for first-year anesthesiology residents to learn the LP procedure. This approach could be particularly useful in settings with limited resources and a lack of sufficient patients to practice on, as it provides an opportunity for faster learning and increased self-confidence.
RESUMEN
Abstract: Introduction: Simulation-based training has become a comprehensive practice to improve skill levels in procedures such as intubation. Clinicians performing endotracheal intubation must be competent to perform this technical skill safely. Objective: Determine the success of the use of mobile remote technology in learning intubation laryngoscopy during training in the hospital. Material and methods: Experimental, cross-sectional, comparative, non-blind, randomized study which was made up of 117 students of the Bachelor of Medicine degree at the Autonomous University of Nuevo Leon. Results: Group A with conventional laryngoscopy achieved successful intubation in an average of 106.86 ± 84.87 seconds, group B in 62.90 ± 65.81 and when crossing the groups in the technique, the time of video laryngoscopy was taken, where group A reported an average time of 64.25 ± 34.23, while the time recorded in group B was 84.25 ± 55.67 seconds. Conclusion: The use of mobile remote technology is effective for the preparation of doctors and future doctors when performing an orotracheal intubation. Videolaryngoscopy was significant to conventional laryngoscopy when performed in inexperienced personnel.
Resumen: Introducción: El entrenamiento basado en simulación se ha convertido en una práctica integral para mejorar los niveles de habilidad en procedimientos como la intubación. Los médicos que realizan intubación endotraqueal deben ser competentes. Objetivo: Determinar el éxito del uso de la tecnología remota móvil en el aprendizaje de la laringoscopía de intubación durante la formación en el hospital. Material y métodos: Estudio experimental, transversal, comparativo, no ciego, aleatorizado que contó con 117 estudiantes de la Licenciatura en Medicina de la Universidad Autónoma de Nuevo León. Resultados: El grupo A con laringoscopía convencional logró intubación exitosa en un promedio de 106.86 ± 84.87 segundos, el grupo B en 62.90 ± 65.81 y al cruzar los grupos en la técnica se tomó el tiempo de videolaringoscopía, donde el grupo A reportó un tiempo promedio de 64.25 ± 34.23, mientras que el tiempo registrado en el grupo B fue de 84.25 ± 55.67 segundos. Conclusión: El uso de tecnología remota móvil es efectivo para la preparación de médicos y futuros médicos a la hora de realizar una intubación orotraqueal. La videolaringoscopía fue significativa para la laringoscopía convencional cuando se realizó en personal sin experiencia.
RESUMEN
ANTECEDENTES: Una de las principales complicaciones de la diabetes mellitus es la amputación de alguna extremidad. En todo el mundo, la prevalencia de amputaciones asociadas a la diabetes es muy variada y tiene un impacto considerable en la calidad de vida del paciente. OBJETIVO: Analizar la frecuencia de las amputaciones en el Hospital Universitario Dr. José E. González y evaluar si se presenta un patrón estacional. MÉTODO: Se realizó un estudio retrospectivo de 2009 a 2012, en el que se revisaron los expedientes de pacientes diabéticos que se sometieron a amputación. La estacionalidad se analizó con la bondad de ajuste de ji al cuadrado. RESULTADOS: Se analizaron 456 amputaciones. Los resultados muestran que febrero es el mes que presenta la mayor frecuencia de amputaciones. La estación anual con mayor número de amputaciones fue el invierno. CONCLUSIONES: Las amputaciones en pacientes diabéticos del área metropolitana de Monterrey presentan un patrón estacional, siendo los meses de invierno los de mayor frecuencia. BACKGROUND: The amputation of an extremity is a main complication of Diabetes mellitus. Worldwide the prevalence of amputations associated with diabetes mellitus is variable and had a considerable impact in the quality of life. OBJECTIVE: Analyze the frequency of amputations in the University Hospital, Dr José E González and evaluate if a seasonal pattern is present. METHOD: A retrospective analysis from 2009 to 2012 was carried out. Clinical files of diabetic patients undergoing to amputation were studied. The seasonality was evaluated with a chi square goodness of fit. RESULTS: A total of 456 amputations were studied. Results shown that February was the month with highest frequency of amputations while winter was the annual season with highest frequency of amputations. CONCLUSIONS: Amputations of diabetic patients from Metropolitan Monterrey Mexico show a seasonal pattern being the winter months those that present highest frequency.

Background. Medications are not exempt from adverse drug reactions (ADR) and how the physician perceives the risk of prescription drugs could influence their availability to report ADR and their prescription behavior. Methods. We assess the perception of risk and the perception of ADR associated with COX2-Inbitors, paracetamol, NSAIDs, and morphine in medical students and residents of northeast of Mexico. Results. The analgesic with the highest risk perception in both group of students was morphine, while the drug with the least risk perceived was paracetamol. Addiction and gastrointestinal bleeding were the ADR with the highest score for morphine and NSAIDs respectively. Discussion. Our findings show that medical students give higher risk scores than residents toward risk due to analgesics. Continuing training and informing physicians about ADRs is necessary since the lack of training is known to induce inadequate use of drugs.
RESUMEN
OBJECTIVE: To analyze the place of death from cancer in México from 1999 to 2009 and find the associated factors. METHODS: We collected data on mortality by cancer from the national database including age, gender, area of residence, level of education, place of death, and type of cancer. RESULTS: The proportion of deaths at home and hospital was 55.67% and 39%, respectively. Factors associated with home deaths were old age, female gender, rural area of residence, and lack of formal education. There was a short but significant decrease in home deaths for cervical cancer and leukemia. CONCLUSIONS: In México, mortality in home is greater than in hospital for patients with cancer. Our results have important implications for palliative care professionals and health services of México.
