Preganglionic Injury of C8 Nerve Root Secondary to Shoulder Disloca tion: Diagnosis based on MRI Findings.

INTRODUCTION: Traumatic spinal root injury caused by shoulder dislocation may involve the brachial plexus or, in some cases, a single nerve. The degree of severity of the injury depends on many patient-specific factors as well as the mechanism of injury. It is essential to suspect this type of lesion by means of a thorough physical examination in order to have better patient outcomes. CASE PRESENTATION: We presented the subtle magnetic resonance imaging (MRI) findings in a 35-yearold male with left shoulder trauma and dislocation after falling off a bicycle. He complained of decreased muscle strength and sensitivity in the C8 dermatome. Atrophy of the hypothenar region and flexion deformity of the 4th and 5th digits were noted. Magnetic resonance imaging findings were consistent with a partial preganglionic C8 motor root lesion. We found T2 increased signal intensity and thinning of the intradural segment of the C8 motor nerve root and low signal in the sequence of a multi- echo gradient recalled echo (GRE). CONCLUSION: MRI is a noninvasive tool that allows a detailed anatomical characterization of the nerves. In brachial plexus injuries, the use of the GRE sequence is useful to identify the lesions, even if they are subtle; however, some lesions may go unnoticed. It is important to note that these patients require an interdisciplinary group to reach a correct diagnosis, which is vital to establish the appropriate treatment and follow-up.

Ergonomics in digestive endoscopy: Prevalence, types of musculoskeletal disorders, and risk factors in endoscopists in Colombia / Ergonomía en endoscopia digestiva: prevalencia, tipos de trastornos musculoesqueléticos y factores de riesgo en endoscopistas de Colombia

Abstract Introduction: The practice of digestive endoscopy is a physically demanding activity, with musculoskeletal disorders present in 39 % to 89 % of endoscopists, associated with "excessive use" maneuvers. Due to a lack of knowledge of this problem in endoscopists in Colombia, the main objective is to determine the prevalence, types, and risk factors of musculoskeletal disorders in specialists and graduate students. The secondary objective is to identify the occupational impact, treatments used, and importance of prevention and education in ergonomics. Materials and methods: Analytical cross-sectional observational study. Electronic survey methodology, open from June 1 to 30, 2021. Purposive sampling of 450 endoscopists from four scientific associations and eleven graduate programs, including 50 questions in six groups according to the objectives. We validated 203 responses, with 131 confirmations of musculoskeletal disorders, the group on which the analysis was performed. Results: Global prevalence of musculoskeletal disorders of 64.5 % and prevalence in graduate students of 58.6 %. There was more significant involvement of the upper limbs (right shoulder, left thumb, right elbow), followed by lower back, neck, knees, and hips. Graduate students reported pain in the right hand/fingers (right thumb) and the lower back. There was no significant difference due to work factors, but there was a tendency for more reports when increasing the volume of procedures and years of professional practice. The labor impact showed 78 % absenteeism. The most used treatments were medication, physiotherapy, and rest; 93.8 % had not received ergonomic education. However, there is a positive perception (74.1 % to 90.9 %) of receiving formal training. Discussion: The prevalence reflected the health and safety problem for the endoscopist. Demographic risk factors plus those of the endoscopic practice give rise to an individualized risk framework that enables endoscopists to understand learning and training as a way to prevent musculoskeletal disorders in themselves and their work team.

Resumen Introducción: la práctica de la endoscopia digestiva es una actividad físicamente exigente, con trastornos musculoesqueléticos presentes en el 39 % a 89 %, asociados con maniobras de "uso excesivo". Debido al desconocimiento de este problema en endoscopistas de Colombia, el objetivo principal fue determinar la prevalencia, tipos y factores de riesgo del trastorno musculoesquelético en especialistas y estudiantes de posgrado. El objetivo secundario fue identificar el impacto laboral, los tratamientos utilizados y la importancia atribuida a la prevención y educación en ergonomía. Metodología: estudio observacional de corte transversal analítico. Metodología de encuesta electrónica, abierta del 1 al 30 de junio de 2021. Muestreo intencionado a 450 endoscopistas de 4 asociaciones científicas y 11 programas de posgrado, en el que se incluyeron 50 preguntas en 6 grupos según los objetivos. Se validaron 203 respuestas, con 131 confirmaciones de trastornos musculoesqueléticos, grupo al cual se le realizó el análisis. Resultados: prevalencia global de trastornos musculoesqueléticos de 64,5 % y prevalencia en estudiantes de posgrado de 58,6 %. Hubo mayor afectación de miembros superiores (hombro derecho, pulgar izquierdo, codo derecho); luego, en la espalda baja y cuello; y en las rodillas y caderas. En estudiantes de posgrado se registró dolor en la mano-dedos derechos (pulgar derecho) y en la espalda baja. No hubo diferencia significativa por aspectos laborales, pero hubo tendencia a un mayor reporte al aumentar el volumen de procedimientos y años de práctica profesional. El impacto laboral mostró 78 % de ausentismo laboral. Los tratamientos más empleados fueron medicamentos, fisioterapia y reposo. El 93,8 % no había recibido capacitación ergonómica y hay percepción positiva (74,1 % a 90,9 %) de recibir una didáctica formal. Discusión: la prevalencia evidenció el problema de salud y seguridad para el endoscopista. Los factores de riesgo demográficos más los propios de la práctica endoscópica generan un marco de riesgo individualizado que le permite al endoscopista entender el aprendizaje y la capacitación para prevenir trastornos musculoesqueléticos en sí mismo y su equipo de trabajo.

Impact of the COVID-19 pandemic on digestive endoscopists: an Ibero-American study.

INTRODUCTION: the COVID-19 pandemic has seriously affected the world population, and has put health personnel in the spotlight as they are tasked with its management. Given their important role in the current health crisis, physicians have been heavily affected in terms of their professional practice, financial conditions and physical and mental health. The objective of this study was to determine the consequences of the COVID-19 pandemic for Colombian endoscopists and compare the effects on endoscopists from South America and from Spain. METHODS: in June 2021, an electronic survey was sent to 292 endoscopists from Colombia, South America and Spain to determine the impact of the pandemic on their professional practice, economic situation, physical and mental health, and training of the residents under their charge. Participants were recruited via convenience sampling. RESULTS: a reduction in the number of endoscopic procedures was reported by 69.9 % of the respondents, and 72.3 % of endoscopists in Colombia stated that their income had decreased. Regarding the doctor-patient relationship, 43.8 % of the respondents believed it had worsened. In addition, 70.9 % reported having experienced changes in their emotional state, especially those related to feeling sad or depressed, and 56.5 % reported that the pandemic had negatively affected the training of residents. Finally, 24.7 % of endoscopists tested positive for COVID-19, and 19.2 % reported the death of a family member due to COVID-19. CONCLUSION: the COVID-19 pandemic has had a negative impact on the professional practice, financial situation and physical and mental health of Ibero-American endoscopists. These problems must be identified in a timely manner to develop and implement strategies aimed to prevent their occurrence.

Teleneurorehabilitation program (virtual reality) for patients with balance disorders: descriptive study.

BACKGROUND: Balance disorders are common in patients with neurological or vestibular diseases. Telerehabilitation program is a treatment to be as safe as conventional treatment. One of the most used methods to perform telerehabilitation is the incorporation of Virtual Reality. In general, rehabilitation programs train predictive postural control, so the patient does not always acquire the necessary autonomy to react to situations of instability. On the other hand, the objective and systematic supervision and measurement of these programs is limited, making it necessary to create clinical protocols with precise and measurable rehabilitation objectives. This study present the training selection methodology and clinical protocol for patients with balance disorders inserted in a Telerehabilitation Program based on Virtual Reality. METHODS: Descriptive study where physiotherapists were trained to use RehaMetrics®. To evaluate their level of agreement in the selection of the exercise clusters developed, the Interobserver Reliability was measured through the kappa statistic. Subsequently, the exercises were applied to a group of patients recruited with sedentary trunk control (Berg Balance Scale = 3 points in item 3), mild or normal cognitive level (Montreal Cognitive Assessment> 21 points), and prescribed for tele-rehabilitation by a doctor. RESULTS: The agreement among the expert physiotherapists irrespective of the cluster exceeds 80%, which indicates a very good strength of agreement, while the novices reached a level of agreement of 45%, which suggests a moderate strength of agreement. All clinical outcomes showed statistically significant differences between the median times, as did the Maximum Width Left Side (MWLS) (cm). The average number of minutes of training was 485.81 (SD 246.49 min), and the number of sessions performed during the 4 weeks of intervention was 17 (SD 7.15 sessions). CONCLUSIONS: This analysis what had excellent interobserver reliability with trained physiotherapists. Regarding the second phase of the study, the results show a statistically significant difference between the initial and final evaluation of the clinical tests, which could result in better performance in aspects such as: balance, gait functionality, meter walked and cognition. Telerehabilitation Program based on Virtual Reality is an excellent alternative to provide continuity of treatment to patients with balance disorders.

Prolonged Periorbicular Edema After Injection of Hyaluronic Acid for Nasojugal Groove Correction.

The injection of hyaluronic acid (HA), a naturally occurring biopolymer, is a common cosmetic procedure. Despite their efficacy and growing adaptation by the medical community, HA fillers occasionally give rise to adverse events. Adverse events from HA fillers range from temporary, such as edema and erythema, to more long-term effects, including granulomas or, in rare cases, sequelae from vascular occlusion. Here, we present a case of a 61-year-old Caucasian woman with prolonged infraorbital hollow edema after injection of HA filler for nasojugal groove correction. We review the anatomy of the nasojugal area and differing injection techniques as a possible explanation for the development of prolonged edema. Similarly, the rheological properties of the specific hyaluronic acid used during this procedure might be crucial in the development of this complication.

Barbed Suture versus Conventional Suture for Vaginal Cuff Closure in Total Laparoscopic Hysterectomy: Randomized Controlled Clinical Trial.

STUDY OBJECTIVE: To determine the surgical time, suture time, presence of postoperative dyspareunia, and complications that occur after closing the vaginal cuff with a barbed suture compared with conventional suture. DESIGN: A randomized, controlled clinical trial (Canadian Task Force classification I). SETTING: Private gynecologic clinic in Medellin, Colombia. PATIENTS: One hundred fifty women who underwent total laparoscopic hysterectomy for benign pathology. INTERVENTIONS: The patients underwent total laparoscopic hysterectomy with intracorporeal closure of the vaginal cuff and were randomized to 2 groups, 1 using a barbed suture (V-Loc 90; Medtronic/Covidien, New Haven, CT) and 1 using polyglactin 910 (coated Vicryl suture; Ethicon/Johnson & Johnson, New Brunswick, NJ). MEASUREMENTS AND MAIN RESULTS: The total operative time, closing time of the vaginal vault, presence of complications in the cuff, and incidence of postoperative dyspareunia were recorded. The patients were evaluated at a postoperative office visit 2 weeks after the procedure and by telephone interview at 24 weeks. Seventy-five patients were included in the barbed suture group and 75 patients in the polyglactin 910 group. The average time to complete the suture of the vaginal cuff was 12.01 minutes (± 5.37 standard deviation) for the barbed suture group versus 13.49 minutes (± 6.48) in the polyglactin 910 group (95% confidence interval, -.44 to 3.4; p = .130). Blood loss was 31.56 ± 22.93 mL in the barbed suture group versus 30.82 ± 21.75 mL in the polyglactin 910 group (95% confidence interval, -7.95 to 6.47; p = .840). The frequency of postoperative events such as hematoma, cellulitis, cuff dehiscence, fever, emergency consultation, and hospitalization was not statistically significant between groups. No statistically significant difference was found regarding deep dyspareunia at 24 postoperative weeks. CONCLUSION: No differences were found in surgical time or frequency of adverse events when comparing patients after vaginal cuff closure with barbed suture versus polyglactin 910.

Esclerodermia en el Caribe: características en una serie de casos dominicana / Scleroderma in the caribbean: characteristics in a dominican case series

Introducción. La esclerodermia es una enfermedad rara, de la cual existe información limitada en América Latina. Estudios preliminares en genética muestran que la ascendencia de República Dominicana tiene fuerte influencia africana, lo cual podría modular la expresión de la enfermedad. El propósito de este estudio es describir las características clínicas y demográficas de esclerodermia en una serie de pacientes dominicanos. Materiales y métodos. Se seleccionaron los pacientes que cumplieron con los criterios del EULAR/ACR para esclerosis sistémica de la base de datos del servicio de reumatología de un centro terciario. Se definieron los subtipos de esclerodermia de acuerdo a la clasificación EULAR. La información clínica y demográfica al momento del diagnóstico fue obtenida de forma retrospectiva de los expedientes médicos. Resultados. La prevalencia fue estimada de 9,3 por millón de habitantes. Veinte y seis pacientes entraron al estudio. La edad media al momento del primer síntoma fue 32,6 ± 15 años; el 68% de los pacientes tenía 40 años de edad o menos cuando aparecieron los síntomas. El 73,1% de los pacientes fue de sexo femenino, con una relación mujer:hombre 2,7:1. Los sistemas orgánicos más afectados fueron el pulmonar y el gastrointestinal; la afectación renal fue rara. Los anticuerpos anti-Scl-70 se encontraron positivos en el 64% de los casos y, en 2 casos, en coexistencia con anticentrómero. Conclusiones. La prevalencia de esclerosis sistémica es menor en la población dominicana que la reportada internacionalmente. La edad de inicio de la enfermedad parece ser menor en la población dominicana que la reportada en la literatura. Un patrón distinto de autoanticuerpos es observado en esta población (AU)

Introduction. Scleroderma is a rare disease with limited data in Latin America. Preliminary genetic studies suggest a strong African ascendance in the Dominican Republic, which could modulate the expression of the disease. The objective of this study is to describe the clinical and demographic characteristics of scleroderma in a series of 26 Dominican patients. Materials and methods. Patients who fulfilled the EULAR/ACR criteria for scleroderma were selected from the Rheumatology Department of a tertiary health center; systemic sclerosis subtypes were defined according to the EULAR classification. Clinical and demographic information was obtained retrospectively from clinical records. Results. Mean age at time of onset was 32.6±15 years; 68% of patients had 40 years of age or less. 73% of patients were females, with a female:male ratio of 2.7:1. The most affected systems were pulmonary and gastrointestinal; renal affection was scarce. Anti-Scl-70 antibodies were positive in 64% of patients, sometimes in coexistence with anti-centromere antibodies. Conclusions. The prevalence of systemic sclerosis is lower in the Dominican population than was reported elsewhere. The age of onset of the disease seems to be lower in the Dominican population than that reported in literature. A different pattern of autoantibodies is observed in this population (AU)

Transversus abdominis plane block after ambulatory total laparoscopic hysterectomy: randomized controlled trial.

OBJECTIVE: To determine if transversus abdominis plane anesthetic blockage (TAP block) diminishes early postoperative pain scores and facilitates ambulatory management following total laparoscopic hysterectomy. DESIGN: Randomized triple blind trial. SETTING: Gynecological endoscopy unit at a referral center for laparoscopic surgery. POPULATION: A total of 197 patients. METHODS: Comparison of a treatment group receiving TAP block with bupivacaine 0.25% and placebo group with comparably placed bilateral injection of sterile saline solution. MAIN OUTCOME MEASURES: Pain scores at discharge 24, 48 and 72 h after surgery, opioid requirement after procedure. RESULTS: Patients who had TAP block had a significant reduction in their pain score at discharge compared with the placebo group (p = 0.017). There were no significant differences in the pain scores between groups at 24 h (95% CI 1.36-0.133, p = 0.237), 48 h (95% CI 0.689-0.465, p = 0.702) and 72 h (95% CI -0.631 to 0.223, p = 0.347). No differences were found between the groups regarding opioid requirements following the procedure (χ(2)  = 3.62, p = 0.46). CONCLUSION: Although TAP block after a total laparoscopic hysterectomy reduced the pain score at discharge compared with placebo, its role in this setting is debatable due to the possible lack of clinical significance of the small difference found.

[Sciatic hernia as a cause of chronic pelvic pain]. / Hernia ciática como causa de dolor pélvico crónico.

Sciatic hernia constitutes the scarcest group of hernias of pelvic floor; however, they should be considered in the origin of chronic pelvic pain. The proper diagnosis of sciatic hernias has allowed to surgeons treating successfully patients with acute or chronic pelvic pain, with intestinal or ureteral obstruction and with urinary or gluteus sepsis. It has to be considered as differential diagnosis before the finding of a congenital or acquired gluteus mass. Laparoscopist gynecologist should know the existence of this defect, to be familiar with its aspect in laparoscopic view and to know the laparoscopic treatment of this disease.
