Bloqueo del grupo de nervios pericapsulares en cirugía de cadera. ¿Una alternativa que supera lo que conocemos? / Pericapsular nerve group block in hip surgery. An alternative that goes beyond what we know?

La fractura de cadera es una afección usualmente observada en pacientes mayores, propensos a presentar complicaciones y aumento de la morbimortalidad durante el ingreso hospitalario. Recientemente se ha descrito el bloqueo del grupo de nervios pericapsulares (PENG) de cadera, diseñado para proporcionar una analgesia de mayor calidad, favoreciendo la deambulación temprana de los pacientes. Se realizó la búsqueda bibliográfica desde noviembre de 2018 hasta julio de 2021 con las siguientes palabras clave: bloqueo del grupo de nervios pericapsulares, bloqueo PENG, fractura de cadera, artroplastia total de cadera. Se excluyeron los estudios realizados en población pediátrica o en adultos con una indicación diferente a cirugía de cadera; obteniendo 18 artículos para leer a texto completo. Los estudios analizados tuvieron resultados positivos a favor de la realización del bloqueo PENG en la cirugía de cadera. Desafortunadamente la evidencia actual es insuficiente para poder integrar los resultados obtenidos y sacar conclusiones acerca de la efectividad y seguridad del bloqueo PENG.(AU)

Toxina botulínica en el tratamiento del síndrome de dolor miofascial / Botulinum toxin in the treatment of myofascial pain syndrome

Las infiltraciones con toxina botulínica han sido utilizadas en el tratamiento del dolor asociado a múltiples patologías, como distonías focales, espasticidad, cefaleas y dolor miofascial. Sin embargo, los resultados de los diferentes estudios realizados con toxina botulínica en el síndrome de dolor miofascial (SDM) son contradictorios. El objetivo de la presente revisión es analizar la evidencia de la eficacia de la toxina botulínica tipo A (TBA) frente a placebo en la disminución del dolor crónico de origen miofascial.Se realizó una búsqueda bibliográfica en PubMed, Web of Science (WoS), Scielo y Scopus, utilizando las siguientes palabras clave: dolor miofascial, punto gatillo, toxina botulínica y bótox. Los estudios que cumplieron los criterios inclusión fueron once ensayos clínicos que comparaban la TBA frente a solución salina normal (SSN).Aunque en la mayoría de los ensayos clínicos ana­lizados no podemos evidenciar un beneficio de la TBA frente a SSN, no sería acertado concluir que la toxina botulínica no está indicada en el tratamiento de dolor asociado al SDM, dado que existe una selección de pacien­tes muy heterogénea, hay una gran variabilidad en la dosis de toxina botulínica, se usan diferentes técnicas de infiltración de los puntos gatillo (PG), la duración de los estudios es variable y no hay estudios que realicen un análisis costo-efectivo.Se necesitan ensayos clínicos más específicos, con muestras más homogéneas, que nos permitan sacar conclusiones acerca del papel de la TBA en el tratamiento del SDM.(AU)

Botulinum toxin injections have been used in pain treatment associated with pathologies such as focal dystonia, spasticity, headaches and myofascial pain. However, results from botulinum toxin trials in myofascial pain syndrome (MPS) are contradictory.The objective of this paper is to analyze the evidence of botulinum toxin type A (BTA) efficacy compared to placebo in myofascial pain management. Literature search was performed in PubMed, Web of Science (WoS), Scielo and Scopus, using the following key words: myofascial pain, trigger point, botulinum toxin and botox. Eleven clinical trials comparing BTA versus normal saline solution (NSS) met the inclusion criteria. Although most of the clinical trials analyzed cannot demonstrate a BTA superiority, it would not be correct to conclude that botulinum toxin is not indicated in miofascial pain treatment due to the great heterogeneous patient selection, variability in BTA doses, different trigger points (TP) injections techniques, variability in trials duration, and absence of cost-effective analysis.More specific clinical trials are required using homogeneous samples to provide conclusive evidence for BTA in the MPS treatment.(AU)

Características de los neonatos trasladados al hospital de referencia regional en Asturias / Characteristics of the newborns transferred to the regional reference hospital in Asturias

INTRODUCCIÓN: La regionalización de la asistencia neonatal es un punto importante de la asistencia pediátrica de calidad. Los traslados interhospitalarios neonatales forman parte de esta regionalización. OBJETIVO: Analizar las características de los neonatos trasladados al hospital de referencia en Asturias. MATERIAL Y MÉTODOS: Estudio observacional retrospectivo y descriptivo de los pacientes neonatales trasladados al Servicio de Neonatología del hospital regional de referencia, entre enero de 2017 y diciembre de 2018 en Asturias. RESULTADOS: Se incluyeron 136 pacientes (56 mujeres y 80 varones), lo que supone un traslado cada 5 días, el 1,8% de los neonatos nacidos en los hospitales emisores y el 14,4% de los ingresos en el hospital receptor. El 63,2% ingresaron en la unidad de cuidados intensivos y el 36,7% en la sala de cuidados intermedios, con un tiempo de ingreso medio de 9,5 días. El 20,7% eran prematuros. El peso medio al nacimiento fue de 2.983 g. La edad media al traslado fue de 5 días y el 46,3% de los traslados se realizaron durante las primeras 24 horas de vida. Las causas más frecuentes de traslado fueron: respiratorias (25%), neurológicas (14,7%), digestivas (13,2%) e infecciosas (12,5%). El 38% de los pacientes precisó soporte ventilatorio y el 1,4% falleció durante el ingreso. CONCLUSIONES: Los traslados neonatales interhospitalarios son relativamente frecuentes en nuestra región, siendo el distrés respiratorio y los problemas neurológicos las causas más comunes. El análisis de la regionalización de la asistencia neonatal resulta especialmente importante en regiones con escasa natalidad debido a la crisis demográfica

INTRODUCTION: Regionalization of neonatal care is an important point of quality in pediatric care. Neonatal interhospital transfers between regional hospitals and referral centers are part of this regionalization. OBJECTIVE: To analyze characteristics of newborns transferred from the different regional and private hospitals to theregional reference hospital in Asturias during 2017 and 2018. MATERIALS AND METHODS: An observational, descriptive and retrospective study was conducted, including all neonatal patients transferred fron other Asturian hospital to Neonatology Service of HUCA between January 2017 and December 2018, in Asturias. RESULTS: 136 patients were included (56 female and 80 male), which represents a transfer every 5 days, 1.8% of the 7,563 neonates born in the sending hospitals and 14.4% of the neonatal admissions in the receiving hospital. 63.2% of patients were admitted to the neonatal Intensive Care Unit and 36.7% to the neonatal Intermiediate care room with a mean admission time of 9.5 days. 20.7% were preterm newborns. The average born weight was 2,983 g. 20.6% were less than 2,500 g. Average age at transfer was 5 days, being the 46.3% made during first 24 hours of life. The most frequent causes of transfer were: respiratory (25%) neurological (14.7%), digestive (13.2%) and infectous (12.5%). 38% required ventilatory support and 1,4% died during admission. CONCLUSIONS: Neonatal inter-hospital transfers are relatively frequent in our region, with respiratory distress and neurological problems being the most common causes. The analysis of neonatal care regionalization is especially important in regions with low birth rates due to demographic crisis

Cerebral oximetry monitoring in the management of severe hypoxaemia associated with transposition of the great arteries with balloon atrial septostomy. / Monitorización de la oximetría cerebral en el manejo de la hipoxemia severa asociada a la transposición de grandes arterias mediante atrioseptostomía con balón.

Transposition of the great arteries (D-TGA) is one of the most common congenital heart diseases requiring neonatal surgical intervention. In the desperately ill neonate with TGA and the resultant hypoxaemia, acidemia, and congestive heart failure, improvement is often obtained with balloon atrial septostomy (BAS). Current methods employed to evaluate oxygen delivery and tissue consumption are frequently nonspecific. Near infrared spectroscopy (NIRS) allows a continuous non-invasive measurement of tissue oxygenation which reflects perfusion status in real time. Because little is known about the direct effect of BAS on the neonatal brain and on cerebral oxygenation, we measured the effectiveness of BAS in two patients with D-TGA using NIRS before and after BAS. We concluded BAS improves cerebral oxygen saturation in neonates with D-TGA.

Genitourinary Malignancies in Transplant or Dialysis Patients: The Frequency of Two Newly Described 2016 World Health Organization Histopathologic Types.

BACKGROUND: The aim of this study was to revise the histopathologic types of neoplasias in the genitourinary tract and determine the frequency of 2 new entities included in the 2016 book of World Health Organization classification of renal tumors. It is not established so far whether these 2 recently described tumors are the most frequent in association with end-stage kidney disease. METHODS: In a retrospective analysis, we revised the histopathologic type of 37 genitourinary tumors from 21 patients in dialysis and/or submitted to renal transplantation from 2003 to 2016 aiming to find the frequency of acquired cystic disease-associated renal cell carcinoma and clear cell papillary (tubulopapillary) renal cell carcinoma. RESULTS: From the total of 37 tumors, 34 were from native end-stage kidneys, 1 from the pelvis of the transplant kidney, and 2 from the urinary bladder. The frequencies from native kidneys were: papillary carcinoma, 13/34 (38.2%); papillary adenoma, 9/34 (26.5%); acquired cystic disease-associated renal cell carcinoma, 4/34 (11.8%); oncocytoma, 3/34 (8.8%); conventional clear cell renal cell carcinoma, 3/34 (8.8%); and clear cell papillary (tubulopapillary) renal cell carcinoma, 2/34 (5.34%). The pelvis and urinary bladder tumors were high-grade urothelial carcinomas. The patients with urinary bladder tumors had been treated for polyomavirus infection. CONCLUSIONS: The frequencies of acquired cystic disease-associated renal cell carcinoma and clear cell papillary renal cell carcinoma were 11.8% and 5.9%, respectively. However, the spectrum of adenoma/carcinoma papillary tumors composed the majority, 64.7%, of tumors.

Should preconditioning hyperbaric oxygenation protect the liver against ischemia-reperfusion injury? An experimental study in a rat model.

OBJECTIVES: We designed studies to test the hypotheses that hyperbaric oxygen (HBO) therapy should protect liver against subsequent ischemia/reperfusion (I/R) injury are scarce and controversial. The purpose of this study was to clarify some questions about the association of HBO with the processes of liver I/R. METHODS: We divided Wistar rats into 5 groups: (1) SHAM operation, (2) I/R, rats submitted to total pedicle ischemia for 30 minutes followed by 5 minutes of reperfusion; (3) HBO60I/R and (4) HBO120I/R, rats respectively submitted to 60 and 120 minutes of HBO therapy at 2 absolute atmospheres and immediately after submitted to the experimental protocol of I/R; (5) HBO120, rats submitted to 120 minutes of HBO therapy at 2 absolute atmospheres and then immediately after humanely killed. The experimental protocol included (1) serum levels of aspartate and alanine aminotransferase; (2) mitochondrial function; (3) tissue malondialdehyde (MDA); and (4) plasma nitrite/nitrate. Data were analyzed using the Mann-Whitney test and were considered significant P < 5%. RESULTS: The processes of liver ischemia/reperfusion caused tissue injury with hepatic mitochondrial functional impairment. A single exposure to 120 minutes of HBO caused an increase of tissue MDA. The time of HBO exposure as preconditioning before hepatic I/R is critical in the prevalence of beneficial or deleterious effects. Sixty minutes of hyperoxic preconditioning before liver I/R presents systemic benefits, but no significant tissue preservation. One hundred twenty minutes of hyperoxic preconditioning tissue liver benefits predominate compared with systemic benefits. CONCLUSIONS: The HBO preconditioning therapeutic benefits to liver I/R injury are time dependent, suggesting a therapeutic window that needs to be clearly defined in future studies.
