Abstract Introduction: Increasing abdominal pressures could affect pulmonary compliance and cardiac performance, a fact based on which the aim of the present study to detect the cardiopulmonary burden of multiple retractors application during supine versus lateral abdominal surgeries. We hypothesized that surgical ring multiple retractors application would affect the pulmonary and cardiac functions during both lateral and supine abdominal surgeries. Methods: Prospective observational comparative study on forty surgical patients subdivided into two groups twenty each, comparing pulmonary compliance and cardiac performance before, during and after retractors application, group (S) supine position cystectomy surgery, and group (L) lateral position nephrectomy surgery under general anesthesia, Composite 1ry outcome; dynamic compliance C-dyn and cardiac index CI and Other outcome variables ICON cardio-meter were also recorded. Results: C-dyn and C-stat were significantly decreased late during retractor application in lateral compared to supine surgery with significant decrease compared to basal values all over the surgical time. CI was significantly increased after retractor removal in both of the study groups compared to basal values. PAW P was significantly increased in -lateral compared to supine surgery -with significant increase compared to basal value all over the surgical time in both of the study groups. significant increase in DO2I compared to basal value during both supine and lateral positions. Conclusion: Surgical retraction results in a short-lived significant decreases in lung compliance and cardiac output particularly during the lateral-kidney position than the supine position compliance.

OBJECTIVE@#To investigate the effect of 300 mL carbohydrates intake two hours before sur-gery on the gastric volume (GV) in patients positioning in trendelenburg undergoing gynecological laparoscopic procedures by using gastric antrum sonography, and further assess the risk of reflux aspiration.@*METHODS@#From June 2020 to February 2021, a total of 80 patients, aged 18-65 years, body mass index (BMI) 18-35 kg/m2, falling into American Society of Anesthesiologists (ASA) physical status Ⅰ or Ⅱ, scheduled for gynecological laparoscopic procedures positioning in trendelenburg were recruited and divided into two groups: the observation group (n =40) and the control group (n=40). In the observation group, solid food was restricted after 24:00, the patients were required to take 300 mL carbohydrates two hours before surgery. In the control group, solid food and liquid intake were restricted after 24:00 the night before surgery. The cross-sectional area (CSA) of gastric antrum was measured in supine position and right lateral decubitus position before anesthesia. Primary outcome was gastric volume (GV) in each group. Secondary outcome included Perlas A semi-quantitative grading and gastric volume/weight (GV/W). All the patients received assessment of preoperative feeling of thirsty and hunger with visual analogue scale (VAS).@*RESULTS@#Complete data were available in eighty patients. GV was (58.8±23.6) mL in the intervention group vs. (56.3±22.1) mL in the control group, GV/W was (0.97±0.39) mL/kg vs. (0.95±0.35) mL/kg, respectively; all the above showed no significant difference between the two groups (P > 0.05). Perlas A semi-quantitative grading showed 0 in 24 patients (60%), 1 in 15 patients (37.5%), 2 in 1 patient (2.5%) in the intervention group and 0 in 25 (62.5%), 1 in 13 (32.5%), 2 in 2 (5%) in the control group, the proportion of Perlas A semi-quantitative grading showed no significant difference between the two groups (P > 0.05). A total of 3 patients (1 in the intervention group and 2 in the control group) with Perlas A semi-quantitative grading 2 were treated with special intervention, no aspiration case was observed in this study. The observation group endured less thirst and hunger (P<0.05).@*CONCLUSION@#Three hundred mL carbohydrates intake two hours before surgery along with ultrasound guided gastric content monitoring does not increase gastric volume and the risk of reflux aspiration in patients positioning in trendelenburg undergoing gynecological laparoscopic surgery, and is helpful in minimizing disturbance to the patient's physiological needs, therefore leading to better clinical outcome.

Horseshoe kidney (HSK) has a prevalence of 1 in every 500 individuals. The management of patients with HSK is usually conservative, except in the presence of symptoms such as obstruction, stones, glomerulopathies, and tumors. In the following case report, we describe how a bilateral en-block transmesenteric laparoscopic nephrectomy in supine position was performed. A 5-year-old boy, with proximal hypospadias and early onset of chronic kidney disease due to focal segmental glomerulosclerosis on biopsy, underwent a genetic molecular evaluation that confirmed a pathogenic mutation at the WT-1 gene. Due to the increased risk of developing Wilms tumor, he underwent a bilateral transmesenteric nephrectomy. In a five-minute video, we describe how we performed an en-block transperitoneal and transmesenteric laparoscopic nephrectomy with special attention to patient positioning, including the feasibility of performing the dissection of the left renal hilum and isthmus with the patient in supine with no need for repositioning, and then moving to the dissection of the right renal hilum and completion of the procedure. The case herein reported enables us to describe the technical key-points to perform a bilateral en-block laparoscopic nephrectomy with shorter operative time and reduction of blood loss by preserving the entire specimen, without the need for an isthmus transection.

El riñón en herradura (RH) tiene una prevalencia de 1 en cada 500 individuos. El manejo del RH es usualmente conservador, excepto cuando genera síntomas como obstrucción, litiasis, glomerulopatías o tumores. Con este reporte de caso, describimos como se realizó una nefrectomia bilateral en bloque transmesentérica en un paciente con riñón en herradura. Un paciente de 5 años de edad, con hypospadias proximal y desarrollo temprano de enfermedad renal crónica por glomeruloesclerosis focal segmentaria, fue sometido a un estudio molecular que confirmó la presencia de una mutación en el gen WT-1. Dado el alto riesgo de desarrollar tumor de Wilms, se decidió realizar una nefrectomía transperitoneal laparoscópica bilateral. En un video de cinco minutos, describimos como se realizó una nefrectomía transperitoneal y transmesentérica en bloque, con especial atención al posicionamiento del paciente, incluso la viabilidad de realizar la disección del hilio renal izquierdo y el istmo con el paciente en supino, sin necesidad de reposicionarlo, y, después, la disección del hilio renal derecho y el fin del procedimiento. El caso reportado nos permite describir los puntos clave técnicos para realizar una nefrectomía laparoscópica bilateral en bloque con un tiempo operativo más corto y reducción del sangrado al preservar todo el espécimen, sin la necesidad de realizar la transección del istmo.

INTRODUCCIÓN: El síndrome compartimental es una complicación infrecuente pero severa que puede aparecer ante una posición de litotomía prolongada y el uso de perneras. OBJETIVO: Presentar un caso de síndrome compartimental bilateral tras posición de litotomía prolongada asociada con el uso de perneras. MATERIAL Y MÉTODOS: Paciente varón de 43 años sometido a una cirugía urológica en posición habitual de litotomía durante un periodo de 6 horas. A las 2 horas de finalizar la cirugía, el paciente presentó dolor intenso y endurecimiento de compartimento anterior y lateral de ambas piernas, junto con una elevación de la creatina quinasa sérica (valor inicial de 109 U/L que se elevó hasta 7.689 U/L a las 12 horas) y una imposibilidad para la flexión dorsal pasiva de ambos tobillos. El paciente no sentía dolor en el resto de los compartimentos. RESULTADOS: Ante la sospecha de un síndrome compartimental anterolateral, se realizó fasciotomía bilateral urgente, y se observó una disminución de la perfusión muscular y mejoría de la misma tras apertura de la fascia. Se realizaron curas periódicas cada 48 horas, y se observó viabilidad del tejido hasta su cierre definitivo a los 4 días. A las 2 semanas, el paciente presentó fatiga ligera para la deambulación sin ayuda, con tumefacción en el compartimento lateral de ambas piernas. A los 10 meses de evolución, el paciente caminaba sin ayuda y con función muscular completa. CONCLUSIONES: El conocimiento de la asociación del síndrome compartimental y la cirugía laparoscópica prolongada es esencial para un diagnóstico precoz y un tratamiento quirúrgico inmediato, para evitar graves secuelas. Los buenos resultados de nuestro paciente se deben a la rápida actuación, ya que normalmente se suele demorar. Para evitar su aparición o disminuir su incidencia, la posición de litotomía debería limitarse a aquellos momentos de la cirugía en los que sea imprescindible, modificando la posición de las piernas cada dos horas en caso de cirugías prolongadas, para prevenir dicha complicación.

Compartment syndrome is a rare but severe complication resulting from a prolonged lithotomy position and the use of leg loops. PURPOSE: To present a case of bilateral compartment syndrome after prolonged lithotomy position associated with the use of leg loops. METHODS: A 43-year-old man underwent urological surgery in the usual lithotomy position for a 6-hour period. Two hours after the end of the surgery, the patient presented severe pain and stiffening of the anterior and lateral compartments of both legs, elevated serum creatine kinase levels (the baseline value of 109 U/L increased to 7,689 U/L at 12 hours), and inability for passive dorsiflexion of both ankles. The patient reported no pain in the other compartments. RESULTS: Suspicion of an anterolateral compartment syndrome resulted in an urgent bilateral fasciotomy; muscle perfusion was decreased, and it improved after fascial opening. Dressings were changed every 48 hours, and tissue viability was observed until the final closure at 4 days. At two weeks, the patient presented slight fatigue when walking with no assistance, in addition to swelling in the lateral compartment of both legs. Ten months after surgery, the patient walked with no assistance and with complete muscle function. CONCLUSION: Knowledge of the association between compartment syndrome and prolonged laparoscopic surgery is essential for an early diagnosis and immediate surgical treatment to avoid serious sequelae. In our patient, the good outcomes resulted from quick action, since diagnosis is often delayed. Limiting the lithotomy position to those surgical moments in which it is essential and changing the position of the legs every 2 hours during prolonged procedures can reduce the occurrence and incidence of compartment syndrome, preventing this complication.

Objetivos: Evaluar la frecuencia y gravedad de la hemorragia parenquimatosa pulmonar tras la biopsia pulmonar con aguja transtorácica coaxial, según factores de procedimiento, aún no descritos en la literatura. El objetivo de este estudio fue determinar si la elección de la tecnología de biopsia coaxial, el posicionamiento del paciente y la dignidad de la lesión son tres nuevas variables que influyen en el riesgo de hemorragia parenquimatosa tras biopsias coaxiales de pulmón. Métodos: Se revisaron retrospectivamente los registros de 117 pacientes que se sometieron a biopsias con aguja transtorácica del pulmón entre enero de 2018 y abril de 2020. El resultado primario fue la hemorragia pulmonar. Se ha utilizado un sistema de clasificación para clasificar la hemorragia parenquimatosa pulmonar: Grado 0 - Grado 3. Se evaluaron tres variables novedosas relacionadas con el paciente, la técnica y la lesión como predictores de hemorragia pulmonar: tecnología de biopsia coaxial, posición del paciente y dignidad de la lesión. Resultados: De los 117 pacientes, 18 (15,4%) pacientes con tecnología de biopsia coaxial de corte, versus 29 (24,8%) pacientes con tecnología coaxial de núcleo completo mostraron hemorragia significativa en las exploraciones de control posteriores a la biopsia. (IC del 95% 0,06-0,33, p <0,0001). No hubo diferencias significativas en la hemorragia pulmonar entre el diagnóstico histológico benigno y maligno (IC 95% 0,84-4,44, p = 0,1199) y la posición del paciente en decúbito prono o supino (IC 95%: 0,57-2,57, p = 0,6232). Conclusiones: La incidencia y gravedad de la hemorragia pulmonar depende de la tecnología de biopsia coaxial utilizada; siendo mayor en pacientes sometidos a una biopsia con tecnología full-core y menor después del uso de tecnología de corte. En este estudio de pronóstico no se estableció una correlación significativa entre la hemorragia pulmonar parenquimatosa y la posición del paciente o la dignidad de la lesión

Objectives: To evaluate the frequency and severity of pulmonary parenchymal hemorrhage after coaxial transthoracic needle biopsy of the lung, according to procedural factors, not yet described in literature. The aim of this study was to determine whether the choice of the coaxial biopsy technology, patient positioning and the lesion dignity are three new variables influencing the risk of parenchymal hemorrhage after coaxial biopsies of the lung. Methods: Records from 117 patients who underwent transthoracic needle biopsies of the lung between January 2018 and April 2020 have been retrospectively reviewed. The primary outcome was pulmonary hemorrhage. A grading system has been used to classify pulmonary parenchymal hemorrhage: Grade 0 ­ Grade 3. Three novel patient, technique and lesion-related variables were evaluated as predictors of pulmonary hemorrhage: coaxial biopsy technology, patient positioning and lesion dignity. Results: Out of the 117 patients, 18 (15,4%) patients with cutting coaxial biopsy technology, versus 29 (24,8%) patients with full core coaxial technology showed significant hemorrhage on the post-biopsy control scans. (95% CI 0,06-0,33, p<0,0001). No significant difference in pulmonary hemorrhage between benign and malignant histological diagnosis (95% CI 0,84-4,44, p=0,1199) and prone or supine patient positioning (95% CI: 0,57-2,57, p= 0,6232) was found. Conclusions: The incidence and severity of pulmonary hemorrhage depends on the coaxial biopsy technology used; being higher in patients undergoing a biopsy with full-core technology and lower after the use of cutting technology. No significant correlation between parenchymal pulmonary hemorrhage and patient positioning or lesion dignity was established in this prognostic study.

Resumo Contexto A ultrassonografia vascular é o exame de imagem de escolha para rastreamento inicial da compressão na veia ilíaca comum esquerda, cujo achado assintomático pode ser encontrado em até 25% em algumas casuísticas. Objetivo Identificar, pela ultrassonografia vascular, se há diferença na avaliação da compressão na veia ilíaca comum esquerda em mulheres assintomáticas em decúbito dorsal e ao ortostatismo. Métodos Trata-se de um estudo observacional transversal em 50 mulheres voluntárias, sem sintomas de compressão venosa pélvica. Os parâmetros avaliados pela ultrassonografia vascular em decúbito dorsal e ao ortostatismo foram os diâmetros e as velocidades máximas na veia ilíaca comum esquerda no local do cruzamento com a artéria ilíaca comum direita e antes desse cruzamento, além dos índices de velocidade na veia ilíaca comum esquerda no local do cruzamento. Resultados Foram identificados oito casos de compressão significativa na veia ilíaca comum esquerda na avaliação em decúbito dorsal (16%) e somente dois casos (4%) ao ortostatismo. Os diâmetros na veia ilíaca comum esquerda foram estatisticamente maiores (p = 0,002) no local de cruzamento com a artéria ilíaca comum direita ao ortostatismo, e as velocidades e índices de velocidades foram estatisticamente maiores (p < 0,001) em decúbito dorsal. Não houve identificação de compressão significativa na veia ilíaca comum esquerda em ortostatismo quando os índices de velocidades estavam normais em decúbito dorsal. Conclusão Não houve diferença na detecção de compressão significativa da veia ilíaca comum esquerda ao ortostatismo em relação ao decúbito dorsal; no entanto, o estudo mostrou que pode haver menor compressão anatômica da veia ilíaca comum esquerda em posição ortostática.

Abstract Background Vascular ultrasonography is the imaging exam of choice for initial screening for left common iliac vein compression, which is an asymptomatic finding that can be detected in up to 25% of some patient samples. Objective To determine, using vascular ultrasonography, whether findings of left common iliac vein compression in asymptomatic women are different when assessed in the prone and standing positions. Methods This is a cross-sectional observational study of 50 adult female volunteers with no symptoms of pelvic venous compression. The parameters assessed with vascular ultrasonography in the prone and standing positions were diameters and maximum velocities of the left common iliac vein at the point at which it crosses behind the right common iliac artery and before this point, in addition to left common iliac vein velocity indices at the crossing. Results Eight cases of significant compression of the left common iliac vein were identified when assessed in prone position (16%) and just two cases (4%) were identified in the standing position. Left common iliac vein diameters were statistically larger (p = 0.002) at the point where it crosses behind the right common iliac artery in the standing position and velocities and velocity indices were statistically higher (p < 0.001) in the prone position. No significant compression of the left common iliac vein was identified in the standing position when velocity indices were normal in the prone position. Conclusions There was no difference in detection of significant compression of the left common iliac vein when assessed in the standing position in comparison with assessment in the prone position. However, the study showed that anatomic compression of the left common iliac vein may be reduced in the standing position.

ABSTRACT Objective To evaluate the displacement of nerve structures according to the decubitus position of the patient in a magnetic resonance imaging (MRI) study. Methods MRI was performed at a radiology clinic in 20 patients in dorsal and right lateral decubitus. The measurement considered was the shortest distance between the dura mater and the medial wall of the pedicle. Results The largest measurement was 11.6 mm in left lateral decubitus, 12.2 mm in right lateral decubitus, 10.5 mm in right dorsal decubitus, and 9.2 mm in left dorsal decubitus. In some patients the space between the medial wall of the pedicle and the dura mater was larger when in lateral decubitus, while in others when in dorsal decubitus. The mean displacement of the measurements on the left was 1.14 mm and on the right 1.355 mm. Conclusions The structures moved on average little more than 1 mm in the positions studied. The positioning of the patient for surgery does not change the space to be approached, being the surgeon's choice according to his learning curve. Level of evidence II; Prospective study of lower quality.

Abstract Background: There are various approaches to perform an ultrasound guided Quadratus Lumborum Block (QLB). The lateral, posterior, anterior or trans muscular and subcostal paramedian are the various approaches described for performing a QLB. Each of these blocks are aimed to achieve a maximum spread with high volume and low concentration of local anesthetics. Case report: In this novel approach a curvilinear ultrasound probe was used with the patient lying in supine position. The probe was placed longitudinally in the mid axillary line to visualize Quadratus Lumborum Muscle (QLM) in the coronal plane. The needle was then introduced from cranial to caudal direction and catheters were inserted in the Anterior Thoracolumbar Fascia (ATLF) up to a distance of 4-5 cm in 24 patients for an anterior approach to acetabulum fractures. The needle tip and the Local Anesthetic (LA) spread was visible in all patients. All patients except 4 had excellent perioperative pain relief considering stable hemodynamics and VAS 2-3/10 for the first 48 hours. All patients received 1 g intravenous paracetamol each 8 hours. VAS in postoperative period was 2-3/10, in 20/24 patients. In the postoperative period, 4 patients complained of persistent pain, requiring intravenous fentanyl boluses and multimodal analgesia. Mean VAS score was 2.87 from 0-12 hours, 3.14 from 12-24 hours and 3.35 from 24-48 hours. There were no block-related complications in any patient. Conclusion: The supine midaxillary coronal approach to anterior QLB is an effective and feasible approach to QLB which can be performed in supine position.

Resumo Justificativa: Existem várias abordagens para a realização do Bloqueio do Quadrado Lombar (BQL) guiado por ultrassom. Diversas abordagens são descritas para a realização do BQL: paramediana lateral, posterior, anterior ou transmuscular e subcostal, todas com o objetivo de obter a máxima dispersão da solução injetada, usando-se alto volume e baixa concentração de anestésico local. Relato de caso: Nesta nova abordagem, a sonda de ultrassom curvilínea foi usada com o paciente em decúbito dorsal. A sonda foi posicionada longitudinalmente na linha axilar média para visualizar o Músculo Quadrado Lombar (MQL) no plano coronal. A agulha foi introduzida na direção cranial-caudal, e foram inseridos cateteres na Fáscia Toracolombar Anterior (FTLA) até uma distância de 4-5 cm, em 24 pacientes a serem submetidos à correção de fratura do acetábulo pela via anterior. O bisel da agulha e a dispersão do Anestésico Local (AL) eram visíveis em todos os pacientes. Os 24 pacientes, com exceção de quatro, apresentaram excelente analgesia perioperatória, baseando-se na estabilidade hemodinâmica e nos escores EVA de 2-3/10 nas primeiras 48 horas. Todos os pacientes receberam 1 g de paracetamol intravenoso a cada 8 horas. O escore EVA no período pós-operatório foi de 2-3/10, em 20 dos 24 pacientes. No período pós-operatório, quatro pacientes apresentaram queixa de dor persistente, necessitando de bolus de fentanil por via intravenosa e analgesia multimodal. O escore médio da EVA no pós-operatório foi 2,87 entre 0-12 horas; 3,14 entre 12-24 horas e 3,35 entre 24-48 horas pós-operatórias. Não houve complicações relacionadas ao bloqueio em nenhum paciente. Conclusão: A abordagem supina axilar média coronal para BQL anterior é eficaz e viável para BQL, e pode ser realizada com os pacientes em decúbito dorsal.

INTRODUCCIÓN: La Academia Americana de Pediatría recomienda que los lactantes menores de un año duerman en posición supina para prevenir el síndrome de muerte súbita en lactantes (SMSL). OBJETIVO: Describir la posición en que duermen un grupo de lactantes y factores de riesgo asociados al SMSL. SUJETOS Y MÉTODO: Estudio piloto, prospectivo concurrente, de lactantes < 45 días de vida en control sano en Centro Médico San Joaquín UC Christus. Criterios de exclusión: prematurez (edad gestacional < 37 semanas) y patología de base (respiratorias, metabólicas, cardiológicas). Se aplicó encuesta al cuidador principal respecto a datos demográficos y hábitos de sueño, basada en encuesta BISQ (Brief Screening Questionnaire for Infant Sleep Problems) validada en español, dado la inexistencia de instru mentos para < 3 meses. RESULTADOS: Se obtuvo muestra de 100 lactantes de edad 16,78 ± 12,88 días de vida, siendo 57% mujeres. La madre fue el principal informante (84%). El 79% de los lactantes dor mían en decúbito supino, 19% lo hacía de lado y 2% en prono. El 66% dormía en cuna en habitación de los padres, 31% en la cama de los padres. El 74% se quedaban dormidos durante la alimentación. El 28% de los lactantes estaban expuestos a tabaquismo pasivo. El 91% cuidadores estaba informa do sobre la posición segura de sueño, siendo el principal informante el pediatra (54%). CONCLUSIONES: En esta muestra se encontró alto porcentaje de lactantes < 45 días que duermen en posición no segura, siendo frecuente el colecho. Es importante implementar campañas locales de prevención del SMSL que refuercen el hábito de dormir seguro.

INTRODUCTION: The American Academy of Pediatrics recommends, through the implementation of the "Back to Sleep (BTS)" campaign, the supine sleeping position for infant sleeping since it prevents to prevent Sudden Infant Death Syndrome (SIDS). OBJECTIVE: To describe the sleeping position of a group of infants and the risk factors associated with sudden infant death syndrome (SIDS). SUBJECTS AND METHOD: Prospective pilot study, including infants < 45 days of life in well-child care visits at a medical center. Exclusion criteria: Preterm-born infant (gestational age < 37 weeks) and/or comorbidities (pulmonary, metabolic, cardiologic). A brief parental questionnaire was conducted regarding general demographic data and sleep habits. The questioner was based on the BISQ - Spanish version, due to the lack of validated instruments for infants < 3-month-old. RESULTS: We included a sample of 100 infants between 16.78 ± 12.88 days old (57% girls). Mothers were the main information source (84%). 79% of the infants slept in supine position, 19% slept on their sides, and 2% in prone position. Regarding the place where the infants slept, 66% did in their crib in the parents' room and 31% slept in parents' bed. 74% of infants fell asleep while being fed. 28% of infants were exposed to passive smoking at home. 91% of parents were informed about safe sleep positions, reporting that pediatricians were the main source of information (54%). CONCLUSION: We found a high percentage of infants < 45 days of life who slept in an unsafe position, and frequently co-sleep with their parents. Thus, it is important to implement local SIDS prevention campaigns to reinforce safe infant sleep.

The aim of this study was to assess the potential of a prone chest CT for the evaluation of esophageal cancer, as compared with a routine supine chest CT. 69 patients (67±18 years old) with pathologically confirmed esophageal cancers underwent MDCT in the supine and prone positions. The supine CT was performed first, followed by the prone position. Localization and staging of individual esophageal lesions on both the prone and supine CTs were assessed by two thoracic radiologists, using a scoring system that consisted of three confidence scales, and the results were correlated with the endoscopic and surgical findings. The mean confidence score for the detection of esophageal cancer was higher in the prone position (2.58±0.74) than that in the supine position (2.42±0.83) with statistical significance (p=0.002). The mean confidence score for predicting local invasion in the selected patients (n=18) who underwent esophagectomy was also higher in the prone position (2.39±0.85) than that in the supine position (2.06±0.73) with statistical significance (p=0.01). In 10 of 11 cases that showed definitive determination for periesophageal infiltration or adjacent organ invasion on the prone CT (score 3), the corresponding findings were also observed in the post-operative evaluations. In conclusion, prone chest CT for evaluating esophageal cancer could have advantages in regards to the localization of esophageal cancer and predicting local invasion compared to that of routine supine CT and can improve the diagnostic accuracy of chest CTs.

OBJECTIVE: To evaluate the technical feasibility of intranodal lymphangiography and thoracic duct (TD) access in a canine model.MATERIALS AND METHODS: Five male mongrel dogs were studied. The dog was placed in the supine position, and the most prominent lymph node in the groin was accessed using a 26-gauge spinal needle under ultrasonography (US) guidance. If the cisterna chyli (CC) was not opacified by bilateral lymphangiography, the medial iliac lymph nodes were directly punctured and Lipiodol was injected. After opacification, the CC was directly punctured with a 22-gauge needle. A 0.018-in microguidewire was advanced through the CC and TD. A 4-Fr introducer and dilator were then advanced over the wire. The microguidewire was changed to a 0.035-in guidewire, and this was advanced into the left subclavian vein through the terminal valve of the TD. Retrograde TD access was performed using a snare kit.RESULTS: US-guided lymphangiography (including intranodal injection of Lipiodol [Guerbet]) was successful in all five dogs. However, in three of the five dogs (60%), the medial iliac lymph nodes were not fully opacified due to overt Lipiodol extravasation at the initial injection site. In these dogs, contralateral superficial inguinal intranodal injection was performed. However, two of these three dogs subsequently underwent direct medial iliac lymph node puncture under fluoroscopy guidance to deliver additional Lipiodol into the lymphatic system. Transabdominal CC puncture and cannulation with a 4-Fr introducer was successful in all five dogs. Transvenous retrograde catheterization of the TD (performed using a snare kit) was also successful in all five dogs.CONCLUSION: A canine model may be appropriate for intranodal lymphangiography and TD access. Most lymphatic intervention techniques can be performed in a canine using the same instruments that are employed in a clinical setting.

During this Pandemic it has been reported that 5% of cases require an Intensive Care Unit. Certain patients who present hypoxemia, acidosis, electrolyte disorders or adverse effects of drugs such as hydroxychloroquine, may end up in Cardiac Arrest. In these patients, it is recommended to provide high-quality cardiopulmonary resuscitation with all biosecurity measures. What should be done in the event of sudden cardiac arrest? The ethical obligation of health personnel is to resuscitate, but with the responsibility of personal protection, that is, with the precept of the rescuer's safety first. The purpose of this article is to review the protocol on the behavior recommended in the care of patients suffering from cardiac arrest in an environment with a Covid pandemic 19, such as that experienced by the world community today. For care and management protocol, AHA, UK and ILCOR guidelines, as well as publications on prone cardiopulmonary resuscitation, will be considered.

Durante esta Pandemia se ha comunicado que un 5% de los casos requieren de Unidad de Cuidados Intensivos. Determinados pacientes que presentan hipoxemia, acidosis, trastornos electrolíticos o efectos adversos de fármacos como la hidroxicloroquina, pueden terminar en paro cardíaco. En estos pacientes se recomienda proporcionar una reanimación cardiopulmonar de alta calidad con todas las medidas de bioseguridad. ¿Qué se debe hacer frente al caso de un paro cardíaco súbito? La obligación ética del personal de salud es reanimar, pero con la responsabilidad de protección personal, es decir, con el precepto de primero la seguridad del reanimador. El propósito del presente artículo es revisar el protocolo sobre la conducta que se recomienda en la atención del paciente que sufre paro cardíaco en un ambiente con pandemia de Covid-19, como la que vive la comunidad mundial en la actualidad. Para la atención y protocolo de manejo, se tendrán en cuenta las guías de la AHA, del Reino Unido y de la ILCOR, así como las publicaciones de reanimación cardiopulmonar en posición prona.

ABSTRACT Vitamin D is a pleiotropic steroid hormone that modulates the autonomic balance. Its deficiency has been described as an environmental risk factor for multiple sclerosis (MS). The aim of this study was to investigate the serum levels of vitamin D, vitamin D binding protein (VDBP) and vitamin D receptors (VDR) and to evaluate cardiac dysautonomia in MS patients due to bidirectional interaction between vitamin D and the autonomic nervous system. Methods: The current cross-sectional study was conducted on 26 patients with relapsing-remitting MS and on 24 healthy controls. Twenty-four-hour ambulatory blood pressure variability (BPV) was calculated and the participants were evaluated for orthostatic hypotension and supine hypertension. Serum levels of vitamin D, VDBP and VDR were measured. Results: The mean serum vitamin D level was significantly lower in MS patients than in controls (p = 0.044); however there was no significant difference in terms of VDR and VDBP levels between the groups. Supine hypertension and orthostatic hypotension were significant and the 24-hour systolic BPV was significantly decreased in patients with MS (p < 0.05) compared to controls. No correlation was found between vitamin D, VDBP and VDR with supine hypertension, orthostatic hypotension and systolic BPV values (p > 0.05). Also, there was a negative correlation between VDBP and the EDSS (p = 0.039, r = −0.406). Conclusion: There was no correlation between orthostatic hypotension, supine hypertension and systolic BPV values and serum vitamin D, VDBP and VDR in MS patients. Future prospective studies with large number of patients may help us to better understand the relationship between vitamin D and the autonomic nervous system.

RESUMO A vitamina D é um hormônio esteroide pleiotrópico que modula o equilíbrio autonômico. Sua deficiência tem sido descrita como fator de risco ambiental para esclerose múltipla (EM). O objetivo deste estudo foi investigar os níveis séricos de vitamina D, proteína de ligação à vitamina D (VDBP) e receptor de vitamina D (VDR) e avaliar a disautonomia cardíaca em pacientes com EM devida à interação bidirecional entre vitamina D e sistema nervoso autônomo. Métodos: O presente estudo transversal foi realizado em 26 pacientes com EM remitente-recorrente e em 24 controles saudáveis. A variabilidade da pressão arterial ambulatorial (BPV) por 24 horas foi calculada e os participantes foram avaliados quanto à hipotensão ortostática e hipertensão supina. Os níveis séricos de vitamina D, VDBP e VDR foram medidos. Resultados: O nível sérico médio de vitamina D foi significativamente menor nos pacientes com EM do que nos controles (p = 0,044); no entanto, não houve diferença significativa em termos de níveis de VDR e VDBP entre os grupos. Hipertensão supina e hipotensão ortostática foram significativas e a BPV sistólica de 24 horas diminuiu significativamente em pacientes com EM (p < 0,05) em comparação aos controles. Não foi encontrada correlação entre vitamina D, VDBP e VDR com hipertensão supina, hipotensão ortostática e BPV sistólica (p > 0,05). Também houve correlação negativa entre VDBP e EDSS (p = 0,039, r = −0,406). Conclusão: Não houve correlação entre hipotensão ortostática, hipertensão supina e valores de BPV sistólica e vitamina D sérica, VDBP e VDR em pacientes com EM. Futuros estudos prospectivos com grande número de pacientes podem nos ajudar a entender melhor a relação entre vitamina D e sistema nervoso autônomo.

ABSTRACT Obstructive sleep apnea (OSA) occurs in up to 66% of Parkinson's disease (PD) patients, higher than in the general population. Although it is more prevalent, the relationship between OSA and PD remains controversial, with some studies confirming and others denying the relationship of OSA with some risk factors and symptoms in patients with PD. Objective: To determine the factors associated with OSA in PD patients com DP. Methods: A cross-sectional study was performed with 88 consecutive patients with PD from the outpatient clinic. Participants underwent clinical interviews with neurologists and a psychiatrist, assessment using standardized scales (Epworth Sleepiness Scale, Parkinson's Disease Questionnaire, Pittsburgh Sleep Quality Index and, for individuals with a diagnosis of restless legs syndrome/Willis-Ekbom disease, the International Restless Legs Syndrome Rating Scale), and video-polysomnography. Results: Individuals with PD and OSA were older and had less insomnia than those with PD without OSA. Regarding the polysomnographic variables, we observed a lower percentage of stage N3 sleep, a higher arousal index, and a higher oxygen desaturation index in those individuals with OSA, relative to those without OSA. In the multivariate analysis, only the percentage of stage N3 sleep and the oxygen desaturation index were significantly different. Besides this, most of the PD patients with OSA had a correlation with sleeping in the supine position (58% of OSA individuals). Conclusion: The PD patients showed a high prevalence of OSA, with the supine position exerting a significant influence on the OSA in these patients, and some factors that are associated with OSA in the general population did not seem to have a greater impact on PD patients.

RESUMO A Apneia Obstrutiva do Sono (AOS) chega a acometer até 66% dos pacientes com doença de Parkinson (DP), prevalência maior, portanto, que a da população geral. Embora seja mais prevalente, a relação entre AOS e DP permanence controversa, com trabalhos confirmando e outros afastando a relação de AOS com alguns fatores de risco e sintomas em pacientes com DP. Objetivo: Determinar quais fatores estão relacionados à AOS em pacientes com DP. Métodos: Estudo transversal, observacional, realizado com 88 pacientes com DP, provenientes do ambulatório de hospital público. Os pacientes foram submetidos à entrevista clínica com neurologista e psiquiatra, à aplicação de escalas padronizadas (escala de sonolência de Epworth, questionário de qualidade de vida da DP, índice de qualidade de sono de Pittsburgh e, para os indivíduos com diagnóstico de Síndrome das Pernas Inquietas, a escala internacional de graduação da SPI), e vídeo-polissonografia. Resultados: Indivíduos com DP e AOS apresentaram maior idade e menor prevalência de insônia crônica que os indivíduos com DP, sem AOS. Em relação às variáveis polissonográficas, observamos uma baixa proporção de sono N3, elevado índice de microdespertares e maior índice de desaturações nos indivíduos com AOS, em comparação ao grupo sem AOS. Na análise multivariada, apenas a porcentagem de sono N3 e o índice de dessaturação permaneceu significativo. Além disso, a maior parte dos pacientes tem relação com a posição supina (58% dos pacientes com AOS). Conclusão: Pacientes com DP apresentaram prevalência elevada de AOS, a posição supina exerceu influência importante na AOS destes pacientes e alguns fatores que estão associados à AOS na população geral não mostraram impacto significativo nos pacientes com DP.

ABSTRACT Purpose We aimed to compare the outcomes of supine and prone miniaturized percutaneous nephrolithotomy (m-PNL) in the treatment of lower pole, middle pole and renal pelvic stones. Materials and Methods 54 patients who performed supine m-PNL between January 2017 and March 2018 and 498 patients who performed prone m-PNL between April 2015 and January 2018 were included in the study. Of the 498 patients, 108 matching 1: 2 in terms of age, gender, body mass index, American Association of Anesthesiology score, stone size, stone localization and hydronephrosis according to the supine m-PNL group were selected as prone m-PNL group. The patients with solitary kidney, upper pole stone, urinary system anomaly or skeletal malformation and pediatric patients (<18 years old) were excluded from the study. The success was defined as 'complete stone clearance' and was determined according to the 1st month computed tomography. Results The operation time and fluoroscopy time in supine m-PNL was significantly shorter than prone m-PNL group (58.1±45.9 vs. 80.1±40.0 min and 3.0±1.7 min vs. 4.9±4.5 min, p=0.025 and p=0.01, respectively). When post-operative complications were compared according to the modified Clavien-Dindo classification, overall and subgroup complication rates were comparable between groups. There was no significant difference between the groups in terms of the success rates (supine m-PNL; 72.2%, prone m-PNL; 71.3%, p=0.902). Conclusions Supine m-PNL procedure is more advantageous in terms of operation time and fluoroscopy time in the treatment of lower pole, middle pole and renal pelvic stones.

ABSTRACT Purpose: Obesity is accepted as a risk factor for postoperative visual loss due to possible perioperative elevations in intraocular pressure. This study investigated whether intraocular pressure changes differed according to the body mass index of patients undergoing laparoscopic cholecystectomy. Methods: Thirty obese and 30 non-obese patients (body mass index cutoff point, 30 kg/m2) undergoing laparoscopic cholecystectomy were enrolled. Intraocular pressure was measured at baseline (T1), after induction of anesthesia (T2), 5 min after initiation of mechanical ventilation (T3), 5 min after pneumoperitoneum inflation (T4), 5 min after the patient was placed in the head-up position (T5), 5 min after deflation with the patient in the supine position (T6), and 5 min after extubation with the patient in the 30 degrees upright position (T7). Results: The mean intraocular pressure values of the obese and non-obese groups were similar at T1 (16.60 ± 2.93 and 16.87 ± 2.85 mmHg respectively). In both groups, intraocular pressure decreased following initiation of anesthesia (T2) (p<0.001, T2 vs T1). Intraocular pressure values at T7 were significantly higher than those at T1 in the obese (20.38 ± 4.11 mmHg, p<0.001) and non-obese (20.93 ± 4.37 mmHg, p<0.01) groups. There were no significant differences between intraocular pressure values of obese and non-obese patients at any time point. Conclusions: Obesity is not correlated with intraocular pressure during short laparoscopic surgeries with the patient in the head-up position.

RESUMO Objetivo: A obesidade é aceita como um fator de risco para a perda visual pós-operatória devido a possíveis elevações perioperatórias da pressão intraocular. Este estudo investigou se as alterações na pressão intraocular diferem de acordo com o índice de massa corporal dos pacientes submetidos à colecistectomia laparoscópica. Métodos: Trinta pacientes obesos e 30 não-obesos (limiar de índice de massa corporal de 30 kg/m2), submetidos à colecistectomia laparoscópica foram incluídos. A pressão intraocular foi medida no início do estudo (T1), após a indução anestésica (T2), 5 min após o início da ventilação mecânica (T3), 5 min após a insuflação do pneumoperitôneo (T4), 5 min após o posicionamento vertical da cabeça (T5), 5 min após a deflação na posição em decúbito dorsal (T6) e 5 min após a extubação com o paciente na posição vertical de 30 graus (T7). Resultados: Os valores médios da pressão intraocular dos grupos obeso e não obeso foram semelhantes no T1 (16,60 ± 2,93 e 16,87 ± 2,85 mmHg, respectivamente). Em ambos os grupos, a pressão intraocular diminuiu após o início da anestesia (T2) (p<0,001, T2 vs T1). Os valores da pressão intraocular em T7 foram significativamente maiores do que aqueles em T1 nos grupos obesos (20,38 ± 4,11 mmHg, p<0,001) e não obesos (20,93 ± 4,37 mmHg, p<0,01). Não houve diferenças significativas entre os valores de pressão intraocular de pacientes obesos e não obesos em qualquer momento. Conclusões: A obesidade não está correlacionada com a pressão intraocular durante cirurgias laparoscópicas curtas com o paciente em posição de cabeça erguida.
