Abstract
Objective In the present study, we aimed at determining the correlation between tomographic findings of intracranial hypertension and ultrasound measurement of the optic nerve sheath diameter (ONSD).
Methods Observational, descriptive, prospective, cross-sectional pilot study. The present research was performed in a tertiary hospital in Cali, Colombia, from March 2019 to October 2019. Twenty-five patients constituted the intracranial hypertension group, and 25 patients without intracranial hypertension constituted the control group. Ultrasound measurements of the ONSD were assessed using a Sonosite Turbo (SonoSite Inc., Bothell, WA, USA) ultrasound. The computed tomography (CT) images obtained from each patient diagnosed with intracranial hypertension were available in the software of the hospital. The primary outcome was the ultrasound measurement of the ONSD.
Results The ONSD values of the right eye of the intracranial hypertension group ranged from 5.2 to 7.6 mm, and the ONSD of the left eye ranged from 5.3 to 7.3 mm. The global ONSD values, obtained from the average between the right and left eye, were recorded between 5.25 and 7.45 mm. Overall, our study indicated that ultrasound measurements of the ONSD were effective in differentiating a group with intracranial hypertension, previously diagnosed by CT scan images, from patients without this condition. According to the ROC curve, the optimal cutoff point for detecting intracranial hypertension was 5.2 mm.
Conclusions Ultrasound measurements of the ONSD correlated with the measurements obtained from CT scan images, suggesting that the ultrasound technique can be efficient in identifying patients with intracranial hypertension and valuable in cases when CT scan images are not an available option.

Published: December 2022

AbstractMeningiomas arising from the falcotentorial junction are rare, and the selection of the optimal surgical approach is essential. We report a falcotentorial meningioma (FTM) case approached by occipitotranstentorial resection and subtotal tumor resection presenting a satisfactory clinical outcome. The present review sought to reveal the current knowledge regarding the clinical presentation, radiological imaging, and the microsurgical anatomy of FTMs as a form of improving the surgical approach. The selection of the optimal surgical approach is essential for the safe and effective removal of an FTM. Preoperative imaging analysis should identify the anatomical relations of the tumor and guide toward the least disruptive route that preserves the neurovascular structures.

Abstract
Background Ventriculoperitoneal shunt (VPS) has become the standard treatment for congenital hydrocephalus. In the neurosurgical practice, it is a common procedure which usually results in low rates of complication. However, some serious complications can occur, including infections, intestinal perforation, and even death.
Case Description A 19-year-old, female, asymptomatic patient, with a history of appendectomy and revision of the VPS 6 years before, presented spontaneous transanal extrusion of the catheter. Abdominal radiographs and tomography scans showed perforation of the descending colon without peritonitis, with expulsion of the distal tip of the catheter through the anus. The patient underwent removal of the proximal part of the VPS and installation of an external ventricular drain (EVD). On the second postoperative day, there was spontaneous elimination of the distal portion of the catheter, dispensing any additional surgical procedures. With antimicrobial prophylaxis and the contralateral VPS performed, the patient evolved without further complications until discharge. Diverging from cases reported in the literature, the patient in question did not present any abdominal manifestations.
Conclusion Intestinal perforation by VPS may be asymptomatic until anal extrusion occurs. However, the early approach should avoid infections, which are associated with increased mortality. Removing only the proximal catheter, together with antimicrobial prophylaxis, can be an effective, safe and less invasive alternative to manage this complication of VPS.

Published: December 2022

AbstractPneumocephalus is a serious complication following brain trauma. Tension pneumocephalus (TP) is entrapment of a large volume of air in the cranial vault causing mass effect on the brain parenchyma. It is the intracranial counterpart of tension pneumothorax and if neglected, can be life threatening. TP should be timely differentiated from benign pneumocephalus owing to its various nonspecific and lethal complications. Our patient is a 37-year-old male with a history of road traffic accident who presented to our hospital with headache and nasal discharge for the last two days. Computed tomography showed multiple skull fractures and extensive pneumocephalus. His preoperative heart rate was 38 beats per minute that was resistant to pharmacological interventions and required a temporary pacemaker for surgery. He underwent uneventful craniotomy for dura repair and was discharged home with no neurological deficit.

Authors: Nogueira Rúben Malcata , Teixeira Nelson , Ramos Nuno 
Published: December 2022

ResumenEl síndrome del nervio interóseo posterior (NIP) es una condición definida por la neuropatía por compresión de esta rama del nervio radial causada por traumatismos, lesiones ocupantes de espacio, neuritis braquial, o compresión espontánea. Su presentación clínica se caracteriza por un inicio insidioso de los síntomas, generalmente un déficit en la extensión de los dedos sin alteración sensitiva. En este artículo, presentamos un caso clínico de una mujer de 72 años con un lipoma intraneural que causó compresión extrínseca por 11 meses y tuvo una recuperación completa después de la extirpación quirúrgica. Además de la escasez de casos clínicos descritos en la literatura (solo tres hasta la fecha), también destacamos la excelente evolución de la paciente, independientemente de su edad y de la duración de los síntomas.

Published: December 2022

ResumenVarios autores han descrito variaciones en el calibre de las arterias palmares y dorsales propias de cada dedo, que podrían condicionar el éxito de la cirugía reconstructiva de los dedos, especialmente en lo que respecta al uso de colgajos. El objetivo de este estudio es comparar cualitativamente el tamaño de dichas arterias en cada dedo de la mano. Para ello, se han inyectado con látex seis manos procedentes de cadáveres frescos criopreservados. Los dedos han sido preparados mediante la técnica de transparentación de Spalteholz y una variante de ésta con glicerina.Los resultados obtenidos muestran una predominancia de la arteria digital palmar propia del lado cubital en los dedos índice y medio, y en el lado radial en el dedo meñique. Las únicas arterias digitales dorsales propias visibles han sido las del pulgar y la del lado radial del índice. Pese a la regularidad del patrón vascular descrito, se pueden producir variaciones anatómicas en cualquier dedo, lo que obliga al cirujano a explorar al paciente mediante el test de Allen modificado y la ecografía Doppler previamente a cualquier intervención quirúrgica.

Published: December 2022

Abstract
Introduction Endoscopic spine surgery enables the minimally invasive treatment of pathologies affecting the spinal cord and roots. Herein we describe an unprecedented technique Ultrasound-Guided in-plane interlaminar lumbar endoscopic approach with a smartphone and portable light source.
Methods The interlaminar approach was performed in a cadaveric specimen at L4 to 5 and L5 to S1 bilaterally. A curvilinear 2 to 5 MHz ultrasound probe was employed, the puncture was performed with the needle, a guide wire was inserted until the flavum ligament, followed by the dilator and working cannula. A 30° spinal endoscope, with an optical adapter of the endoscope camera for smartphone and portable endoscope lighting was inserted, the flavum ligament was visualized, and an opening in this site was performed with the scissors. Open dissection of the specimen was subsequently performed by identifying the puncture site in the interlaminar window.
Results The four interlaminar punctures were successfully guided by ultrasound; the opening of the ligamentum flavum was performed in the most lateral part of the interlaminar space, near the junction of the superior and inferior articular processes of the corresponding vertebrae in all the punctures.
Discussion The ultrasound makes possible to identify facets, foramina, transverse processes, and the interlaminar space. It is possible to minimize the use of radioscopy and its associated risks, both for patients and health professionals.
Conclusions The ultrasound-guided, in-plane, interlaminar, lumbar endoscopic approach with smartphone-adapted endoscope and portable light source is feasible and practical, minimizing radiation risks and making it possible to perform endoscopic spinal surgery.

AbstractThe learning curve reflects surgeons' experience in managing several patients with the same disease. In skull base surgery, the professional's place on the curve could be related to the number of times the same procedure was performed. Where does curve begin? What amount of training is necessary prior to its application in surgical settings? What were the results of the first few skull base tumor surgeries performed by a surgeon who goes on to produce excellent results, and how is reflected in the start of their learning curve? The only way for neurosurgeons to improve their results from the start is with prior training in the microsurgery laboratory. This learning technique is essential to maximize the chance of success of a neurosurgical procedures, minimizing the morbidity rate to which patients are subjected by less experienced neurosurgeons. This article is divided in two parts, and its purpose is to show how training in the microsurgical laboratory fits into the construction of knowledge about skull base surgery, based on authors' experience and reflections. This first part discusses the technical, psychological, and philosophical aspects of medical knowledge, primarily addressing those training in skull base surgery, the principles of some selected philosophical currents, and their influence on the development of current medical knowledge.

Authors: Vega Pablo Nicolás López-Osornio de , Guedes Giovanni Vilardo Cerqueira 
Published: December 2022

Resumen
Introducción Diferentemente de la artrodesis, la artroplastia total de muñeca permite mantener um rango de movimiento funcional en pacientes operados por artrosis de diferentes causas. La evolución de los implantes pemitió llegar a una mayor tasa de éxito, con disminución de las complicaciones como el aflojamiento de componentes. Este estudio tiene como objetivo demostrar los resultados funcionales y las tasas de complicaciones en una serie de casos operados con el implante Motec (Swemac Orthopaedics AB, Linköping, Suecia) por un único cirujano.
Materiales y Métodos Se trata de un estudio retrospectivo con 14 pacientes intervenidos de artroplastia total de muñeca con el sistema Motec entre 2017 y 2022 y evaluados pre y posoperatoriamente por la Escala de Muñeca de la Clínica Mayo (Mayo Wrist Score, en inglés) y la Escala Visual Analógica (EVA). Se realizó revisión de historias clínicas en junio de 2022 y análisis estadístico con prueba t pareada considerando significativos valores de p < 0,05.
Resultados Fueron operados 13 hombres y 1 mujer, con una edad media de 64,8 (desviación estándar [DE] = 7,5) años, y el tiempo medio de seguimiento fue de 25,1 (DE = 10,9) meses. La puntuación en la Escala de Mayo presentó media preoperatoria de 23,2 (DE = 8,9) y posoperatoria de 82,8 (DE = 7), mientras la EVA preoperatoria tuvo una media de 7,6 (DE = 1,1), y la posoperatoria fue de 1 (DE = 1,2). Las diferencias en los resultados pre y posoperatorios de la Escala de Mayo y la EVA fueron estadísticamente significativas (p < 0,001).
Conclusión Como se demuestra en esta serie, las mejoras funcionales y en el dolor fueron importantes, no hubo complicaciones mayores en el período de tiempo evaluado, y la prótesis fue capaz de reemplazar las artrodesis parciales que fallaron. Los pacientes deben ser seguidos durante más tiempo, pero con la certeza de que, en caso de fracaso, aún se puede realizar una artrodesis total de muñeca.
Artrodesis de articulación interfalángica proximal en enfermedad de Dupuytren: Una revisión sistemática cualitativa
Authors: García Javier Francisco García , González María Segovia , González Alicia González , Baro Alejandro Mendieta , Duque Pablo Benito 
Published: December 2022

Resumen
Introducción La enfermedad de Dupuytren (ED) se caracteriza por una alta tendencia a la recidiva. Las reintervenciones asocian elevado riesgo de complicaciones, incrementado tras cada cirugía. En contracturas graves y recidivantes, con insuficiencia vascular o mala calidad tisular, nuevas fasciectomías pueden estar contraindicadas por el riesgo de comprometer gravemente la viabilidad cutánea. En estos casos, artrodesar la articulación interfalángica proximal (IFP) es una alternativa a la amputación. La artrodesis también es una alternativa en aquellas contracturas que asocien artrosis o artrofibrosis de la articulación IFP. El limitado conocimiento sobre esta intervención se justifica por su escasa frecuencia. Realizamos una revisión sistemática cualitativa de resultados y complicaciones de artrodesis de la articulación IFP del segundo al quinto dedos en adultos con ED.
Materiales y Métodos Según la declaración de los Ítems Preferidos de Reporte para Revisiones Sistemáticas y Metanálisis (Preferred Reporting Items for Systematic Reviews and Meta-Analyses, PRISMA, en inglés), desarrollamos una búsqueda en las bases de datos PubMed, Embase y Cochrane Library. Evaluamos el riesgo de sesgo mediante la Escala de Newcastle-Ottawa modificada. Junto a variables intra y preoperatorias y complicaciones, se registró las mejorías funcional y del dolor, y el grado de satisfacción.
Resultados Para esta revisión sistemática, se seleccionaron 4 series de casos, con 65 pacientes y 71 artrodesis. No evidenciamos mejorías significativas en términos de dolor o funcionalidad, pero sí un alto grado de satisfacción en todos los estudios. El 11,3% de las complicaciones incluyó una necrosis cutánea, pero ninguna lesión vascular o nerviosa.
Conclusión Pese a no demostrar mejoría en dolor o funcionalidad, este procedimiento asocia alto grado de satisfacción y muy baja tasa de afectación cutánea o de lesiones vasculares o nerviosas. El nivel de evidencia sobre resultados y complicaciones es bajo.
The hot spots and frontiers of research on the Grand Canal Culture Belt in China: Literature and academic trends
Authors: Chen Ying 
Published: December 2022

AbstractThe construction of the grand canal cultural belt is the first zonal development strategy in China starting from the Spring and Autumn Periods. In recent years, it performs the link between the oceangoing Maritime Silk Road and the land-based Silk Road to promote a national policy of “One Belt and One Road”. In order to fully understand global academic hot spots and the corresponding trajectory in the research of the grand canal culture belt from 1976 to 2022, the literature review is based on 256 publications from ISI Web of Science, 4944 bibliographic records retrieved from China Academic Journals Full-Text Database, 472 articles under the theme of the cultural economy from Chinese Social Sciences Citation Index, and visualized by the scientometric software of CiteSpace. Meanwhile, comparisons of research areas with canal studies in both China and other global famous canals are implemented, including the Grand Canal of China, the Venice Canal of Italy, the Panama Canal of Panama, the Colorado River of the USA, the Nile Delta of Egypt, Nicaragua Canal of USA, Welland Canal of Canada, especially four canal studies cases on keywords and knowledge clusters: Grand Canal of China, Venice Canal of Italy, Nile Delta of Egypt, Rhine-Marne Canal of France. The study identifies major intellectual cooperation networks, cooccurrence keywords, research clusters, and landmark articles, including: (1) International grand canal research tendencies gradually extend the discussions from water conservancy to the cultural economy since Chinese scholars publish more articles on grand canal cultural belt, especially from the year of 2016; (2) Government-issued culture development planning and high diversity of grand canal culture belt are two crucial driven factors affecting the changes in the theme of Chinese studies. Finally, this study summarizes the future research directions that could be expanded in two ways: (1) Increase the multidisciplinary perspective of research and strengthen the cooperation of researchers and (2) Transfer the theoretical research results into canal heritage protection and development practice to fully develop the value of canal.
Hydrodynamic simulations of directed flow for light hadrons in Au+Au and isobar collisions at

200 GeV*
Authors: Jing Jing , Jiang Ze-Fang , Yang C. B. , Zhang Ben-Wei 
Published: December 2022

Abstract
Using a (3+1)-D hydrodynamic model, CLVisc, we study the directed flow (

) of light hadrons produced in Au+Au, Ru+Ru, and Zr+Zr collisions at

200 GeV. The evolution of tilted energy density, pressure gradient, and radial flow along the x-direction is systematically investigated. The counter-clockwise tilt of the initial fireball is shown to be a vital source of directed flow for final light hadrons. A good description of directed flow is provided for light hadrons in central and mid-central Au+Au and isobar collisions at the RHIC. Our numerical results show a clear system size dependence for light hadron

across different collision systems. We further study the effect of nuclear structure on the directed flow and find that

for light hadrons is insensitive to nuclei with quadrupole deformation.
Hybrid normal-superconducting Aharonov-Bohm quantum thermal device
Authors: Blasi Gianmichele , Giazotto Francesco , Haack Géraldine 
Published: December 2022

Abstract
We propose and theoretically investigate the behavior of a ballistic Aharonov-Bohm (AB) ring when embedded in a N-S two-terminal setup, consisting of a normal metal (N) and superconducting (S) leads. This device is based on available current technologies and we show in this work that it constitutes a promising hybrid quantum thermal device, as a quantum heat engine and quantum thermal rectifier. Remarkably, we evidence the interplay of single-particle quantum interferences in the AB ring and of the superconducting properties of the structure to achieve the hybrid operating mode for this quantum device. Its efficiency as a quantum heat engine reaches

55
%

of the Carnot efficiency, and we predict a thermal rectification factor attaining 350%. These results make this device highly promising for future phase-coherent caloritronic nanodevices.
