Meta-analysis of Distribution Frequency of Traditional Chinese Medicine Syndrome in Primary Osteoporosis / 中国实验方剂学杂志

ObjectiveTo systematically evaluate the distribution of traditional Chinese medicine（TCM） syndromes of primary osteoporosis（POP） in China by using evidence-based medicine methods， and to understand the distribution law of the syndromes. MethodChina National Knowledge Infrastructure（CNKI）， VIP Chinese Science and Technology Journal Database（VIP）， WanFang Data Knowledge Service Platform（WanFang） and China Biology Medicine（CBM） were searched to obtain representative literature， and each database was searched from the 1994 World Health Organization defined diagnostic criteria for osteoporosis until May 1， 2023. Two researchers independently screened literature according to the criteria， extracted data， and cross-checked them. Meta analysis was conducted using R4.1.3， and subgroup analysis was performed. ResultA total of 56 Chinese papers were included， involving 14 415 patients. After standardized classification of syndromes， 11 articles were excluded， and Meta analysis results of the ultimately included 45 Chinese articles showed that the distribution frequencies of liver-kidney Yin deficiency syndrome， spleen-kidney Yang deficiency syndrome and kidney deficiency and blood stasis syndrome in 12 723 patients were 27%［95% confidence interval（CI） 0.24-0.31］， 32%（95% CI 0.29-0.36）， 36%（95% CI 0.30-0.42）. Subgroup analysis showed that there was a statistically significant difference in the distribution of the three TCM syndromes in the north and south（P<0.05）. In addition， the incidence of TCM syndrome fractures in different types of POP was 15%（95% CI 0.09-0.24） for liver-kidney Yin deficiency syndrome， 20%（95% CI 0.12-0.30） for spleen-kidney Yang deficiency syndrome， and 31%（95% CI 0.25-0.39） for kidney deficiency and blood stasis syndrome. ConclusionThe distribution of syndromes in POP patients is mainly kidney deficiency， accompanied by liver and spleen dysfunction. Liver-kidney Yin deficiency syndrome， spleen-kidney Yang deficiency syndrome and kidney deficiency and blood stasis syndrome are all the main syndromes of POP and osteoporotic fractures， and kidney deficiency and blood stasis syndrome is most closely related to the development of osteoporotic fractures. The reference standards for syndrome determination among the included studies are inconsistent， and in the future， it is necessary to focus on their determination standards to obtain consensus research results， at the same time， conduct large-scale syndrome research to obtain representative research results， providing a basis for clinical practice and research.

Application of multidisciplinary in situ simulation training in the treatment of acute ischemic stroke: a quality improvement project / 世界急诊医学杂志（英文）

@#BACKGROUND: Ischemic stroke refers to a disorder in the blood supply to a local area of brain tissue for various reasons and is characterized by high morbidity, mortality, and disability. Early reperfusion of brain tissue at risk of injury is crucial for the treatment of acute ischemic stroke. The purpose of this study was to evaluate comfort levels in managing acute stroke patients with hypoxemia who required endotracheal intubation after multidisciplinary in situ simulation training and to shorten the door-to-image time. METHODS: This quality improvement project utilized a comprehensive multidisciplinary in situ simulation exercise. A total of 53 participants completed the two-day in situ simulation training. The main outcome was the self-reported comfort levels of participants in managing acute stroke patients with hypoxemia requiring endotracheal intubation before and after simulation training. A 5-point Likert scale was used to measure participant comfort. A paired-sample t-test was used to compare the mean self-reported comfort scores of participants, as well as the endotracheal intubation time and door-to-image time on the first and second days of in situ simulation training. The door-to-image time before and after the training was also recorded. RESULTS: The findings indicated that in situ simulation training could enhance participant comfort when managing acute stroke patients with hypoxemia who required endotracheal intubation and shorten door-to-image time. For the emergency management of hypoxemia or tracheal intubation, the mean post-training self-reported comfort score was significantly higher than the mean pre-training comfort score (hypoxemia: 4.53±0.64 vs. 3.62±0.69, t= -11.046, P<0.001; tracheal intubation: 3.98±0.72 vs. 3.43±0.72, t= -6.940, P<0.001). We also observed a decrease in the tracheal intubation and door-to-image time and a decreasing trend in the door-to-image time, which continued after the training. CONCLUSION: Our study demonstrates that the implementation of in situ simulation training in a clinical environment with a multidisciplinary approach may improve the ability and confidence of stroke team members, optimize the first-aid process, and effectively shorten the door-to-image time of stroke patients with emergency complications.

Angle Evaluation of Possible Routes that Can Be Used to Reach the Foramen Ovale in the Anterior Approach / Evaluación Angular de Posibles Rutas que se Pueden Utilizar para Alcanzar el Foramen Oval en el Abordaje Anterior

SUMMARY: For the treatment of trigeminal neuralgia, the foramen ovale is reached by entering the cheek with a needle. Thermocoagulation is performed with balloon compression, administration of alcohol or radiofrequency. Apart from the classical method, it is theoretically possible to reach the foramen ovale through the mouth with the anterior approach. In our study, it was aimed to examine horizontally and vertically the angular values that must be given to the needle to reach the foramen ovale in the anterior approach. Three landmark points were determined on both right and left sides of 25 dry skulls. A rod was inserted starting from these landmark points and passing through the center of the foramen ovale. The vertical and horizontal angular values of this bar were measured. For each foramen ovale, 3 vertical angles, 3 horizontal angles and 4 distance measurements were made. There was a significant difference between the right and left sides in terms of horizontal angular values. Average values of horizontal angles (in degrees); on the right, 7.29 for H1, 12.15 for H2, 32.29 for H3; 1.26 for H1, 9.46 for H2, and 30.56 for H3 on the left side (p<0.005). The angle value was measured as 0 or negative value in 5 (20 %) of the H1 angle measurements made on the right side and 14 (56 %) on the left side. The H2 angle value was found to be smaller than the H1 angle in the skull 2 (8 %) on the right and 3 (12 %) on the left. There was no difference between the right and left sides in terms of vertical angular values. A significant difference was found between the right and left sides in the D1, D2, D4 distances (p<0.005). Six important anatomical features affecting angular values were encountered.

Para el tratamiento de la neuralgia del trigémino, se alcanza el foramen oval introduciendo una aguja en la mejilla. La termocoagulación se realiza con compresión con balón, administración de alcohol o radiofrecuencia. Aparte del método clásico, en teoría es posible alcanzar el foramen oval a través de la cavidad oral mediante el abordaje anterior. En nuestro estudio se tuvo como objetivo examinar horizontal y verticalmente los valores angulares que se deben dar a la aguja para alcanzar el foramen oval en el abordaje anterior. Se determinaron tres puntos de referencia en los lados derecho e izquierdo de 25 cráneos secos. Se insertó una varilla comenzando desde estos puntos de referencia y pasando por el centro del foramen oval. Se midieron los valores angulares verticales y horizontales de esta barra. Para cada foramen oval se realizaron mediciones de 3 ángulos verticales, 3 ángulos horizontales y 4 distancias. Hubo una diferencia significativa entre los lados derecho e izquierdo en términos de valores angulares horizontales. Valores medios de ángulos horizontales (en grados); a la derecha, 7,29 para H1, 12,15 para H2, 32,29 para H3; 1,26 para H1, 9,46 para H2 y 30,56 para H3 en el lado izquierdo (p<0,005). El valor del ángulo se midió como 0 o valor negativo en 5 (20 %) de las mediciones del ángulo H1 realizadas en el lado derecho y 14 (56 %) en el lado izquierdo. Se encontró que el valor del ángulo H2 era menor que el ángulo H1 en el cráneo 2 (8 %) a la derecha y 3 (12 %) a la izquierda. No hubo diferencia entre los lados derecho e izquierdo en términos de valores angulares verticales. Se encontró diferencia significativa entre el lado derecho e izquierdo en las distancias D1, D2, D4 (p<0,005). Se encontraron seis características anatómicas importantes que afectan los valores angulares.

Endoscopic Orientation of Juxta-pituitary Carotid in Transsphenoidal Approaches: Critical Considerations for Clinical Applications

Abstract Introduction In sphenoid sinuses with ill-defined carotid bony landmarks, accidental injury of the internal carotid artery (ICA) remains one of the most challenging complications, which is particularly reported in the endoscopic endonasal transsphenoidal approaches (EETAs). Objectives To describe an anatomical model for the endoscopic orientation of the juxta-pituitary segment of the ICA in relation to the lateral opticocarotid recess (OCR) as a nearby bony landmark. Methods Dissection was performed progressively, simulating the EETA, in twenty fresh adult cadavers. After reducing the posterior and lateral walls of the sphenoid sinuses, various measurements were taken from both lateral OCRs to "contact points" on the juxta-pituitary segment of the ICA and lateral margins of the pituitary gland. Results The current results have enabled us to divide the region between the lateral OCRs into 3 compartments: 2 lateral parasellar compartments contain juxta-pituitary segments of the ICA with a mean width of 8 mm and a narrow range from 7 mm to 10 mm; and a central intercarotid sellar compartment represents the safe region for bone drilling, showing widely variable widths ranging from 9 mm to 20 mm. In all specimens, the variation in the width of the intercarotid compartment correlated with the distance between both lateral OCRs. Conclusion The present study improves surgeon awareness of the variations in the course of the ICA through the EETA along sphenoid sinuses with ill-defined bony landmarks. An appreciation of the measurements taken in the present study can help in operative training, and can also provide a base for future studies to confirm ICA courses associated with a higher risk of injury.

Postauricular Transcanal Posterior Tympanectomy (PT2) Approach - A Modified Surgical Technique for Jugulotympanic Paragangliomas

Abstract Introduction The surgical management of jugulotympanic paragangliomas has remained challenging. They are the second most common type of tumor of the temporal bone after acoustic neuroma. It has been noticed by the authors that the jugulotympanic paragangliomas may have extensions to the epitympanum and aditus in addition to the mesotympanum and hypotympanum. The modified technique could be an alternative to the conventional facial recess technique for complete removal of the tumors. Objective To highlight the modified surgical technique for the surgical treatment of jugulotympanic paragangliomas. Methods This is a retrospective review of 34 cases of jugulotympanic paragangliomas treated in a tertiary center with respect to clinical presentation, diagnosis, and surgical treatment. Tinnitus and hearing loss were predominant symptoms. A modified technique of postauricular transcanal posterior tympanectomy with extended hypo-tympanic access was performed in 29 patients. Only two cases were operated with a classical transcanal approach. A canal wall down the mastoidectomy was required in three patients. Results The patients operated on with the modified technique had complete excision evident by absence of any lesion in computed tomography and the disappearance of tinnitus. However, two patients had recurrence of symptoms and presence of tumor in the follow-up period. These two patients underwent revision surgery. None of the patients required postoperative radiotherapy or gamma knife therapy. Conclusions Jugulotympanic paragangliomas can be effectively managed with the modified technique to ensure complete removal of the lesions. This technique has not been reported earlier in the literature.

RESUMEN INTRODUCCIÓN: La pandemia por COVID-19 incidió en los ritmos y frecuencias de consumo de sustancias, así como en su abordaje. El objetivo fue analizar las modificaciones en el consumo de sustancias y en los dispositivos de abordaje territorial respecto a la demanda de atención, y las limitaciones y oportunidades para dar respuesta en contexto de crisis sociosanitaria. MÉTODOS: Se llevó a cabo una investigación cualitativa a través de 10 entrevistas a trabajadores/as que se desempeñaban en dispositivos territoriales del Área Metropolitana de Buenos Aires. El relevamiento de los datos secundarios fue realizado a través de buscadores de la web en sitios oficiales. RESULTADOS: Se identificaron variaciones en el consumo de sustancias y las frecuencias. Se incrementaron las situaciones de vulnerabilidad psicosocial de la población. Las consultas relacionadas con acceso a derechos fueron las más frecuentes. La modalidad remota y el uso de herramientas digitales permitieron continuar con ciertas intervenciones, pero al mismo tiempo tuvieron limitaciones (como sobrecarga de trabajo). Las estrategias implementadas para facilitar la accesibilidad fueron variables. Los equipos refirieron una compleja adaptación a las nuevas modalidades y dinámicas de atención, asistencia y acompañamiento. DISCUSIÓN: La pandemia ha demostrado el rol invaluable de los dispositivos de abordaje territorial. Resulta imperioso acrecentar y fortalecer la red con recursos humanos y materiales acordes.

ABSTRACT INTRODUCTION: The COVID-19 pandemic affected both rhythms and frequencies of substance use as well as its approach. The aim was to analyze the changes in substance use and in territorial community centers related to health care demand, along with limitations and opportunities to provide solutions in the context of a social and health crisis. METHODS: A qualitative research was conducted through 10 interviews to employees working in territorial community centers in the Metropolitan Area of Buenos Aires. The secondary data were collected through web search engines in official sites. RESULTS: Variations in substance use and frequencies have been identified. There was a higher psychosocial vulnerability among the population. Inquiries related to access to rights were the most frequent ones. The remote modality and the use of digital tools allowed some interventions to continue, but at the same time they had limitations (such as work overload). The strategies implemented to facilitate accessibility varied. Teams reported a complex adaptation to new modalities and dynamics of care, assistance and support. DISCUSSION: The pandemic has shown the invaluable role played by territorial community centers. It is of utmost importance to provide human resources and necessary materials to extend and strengthen the network of territorial community centers.

Resumen: Introducción: el bloqueo de plexo braquial con abordaje costoclavicular, ofrece ventajas como sitio de inyección único, sitio adecuado para colocación de catéter de analgesia continua. Objetivo: identificar la visibilidad de los tres cordones del plexo braquial en el espacio costoclavicular según la angulación del brazo. Material y métodos: se realizó un estudio observacional descriptivo y transversal; se incluyeron 99 pacientes entre 18 a 90 años de edad, en un período de dos meses. Se describieron variables continuas, se aplicó la prueba no paramétrica de Friedman para K muestras relacionadas, una regresión lineal para confirmar la correlación entre la distancia de la piel a plexo braquial, peso e índice de masa corporal (IMC). Resultados: se encontró una menor profundidad en relación piel plexo bajo abducción del brazo a una angulación de 90o y 110o, que permite la visualización sonoanatómica del plexo braquial a nivel costoclavicular con significancia estadística. El peso es un factor independiente que determina la distancia entre la profundidad piel plexo. Conclusiones: se determinó que el abordaje del bloqueo costoclavicular ecoguiado es anatómicamente factible con elevada eficacia clínica, el cual concluye ser un sitio anatómico innovador y seguro.

Abstract: Introduction: the brachial plexus block with a costoclavicular approach offers advantages as a single injection site, being a suitable site for continuous analgesia catheter placement. Objective: to identify the visibility of the 3 brachial plexus cords in the costoclavicular space according to the angulation of the arm. Material and methods: a descriptive and cross-sectional observational study was carried out; 99 healthy patients between 18 and 90 years of age were included, in a period of two months. Continuous variables were described, the nonparametric Friedman test was applied for K related samples, a linear regression was performed to confirm the correlation between the distance from the skin to the brachial plexus, weight and body mass index (BMI). Results: a smaller depth was found in relation to the skin plexus under abduction of the arm at an angulation of 90o and 110o, which allows an adequate sonoanatomical visualization of the brachial plexus at the costoclavicular level with statistical significance. Weight is an independent factor that determine the distance between the skin plexus depth. Conclusions: it was determined that the ultrasound-guided costoclavicular block approach is anatomically feasible with greater clinical efficacy, which concludes to be an innovative and safe anatomical site.

A Nonlinear Identification Approach for Gait Analysis of Amyotrophic Lateral SclerosisPatients

Gait data analysis, is giving mixing results regarding locomotion changes associated to Amyotrophic Lateral Sclerosis (ALS) development; the need has been claimed for new tools. We applied a nonlinear identification approach to the study of gait data from both healthy and ALS patients, available from Physionet.org. Kernel nonparametric nonlinear autoregression allowed to obtain noise-free realizations (NFR) that mimicked original traces, though correlation between original data and corresponding NFR was lower among ALS patients (p=0.03), suggesting a higher contribution of stochastic influences. Visual inspection of phase portraits, reconstructed from NFR via Takens theorem application, suggested dynamics differences between control subjects and patients. This was confirmed when phase portrait features were quantified and submitted to discriminant analysis (89% of correct classifications; 24/28). Application of a nonlinear dissimilarity measure for comparing pairs gait recordings, defined as a distance between underlying nonlinear autoregressive functions allowed an excellent separation between ALS and controls, via multidimensional scaling. Obtained projection map clearly suggested that ALS traces lay in a narrower dynamical space. This might reflect the known fact about neuronal degeneration accompanying ALS progression. When dissimilarity matrix principal components were introduced as predicting variables, discriminant analysis yielded an 82% of correct classifications (23/28). Overall, our results suggest that a nonlinear identification approach, centered in the characterization of the dynamics of the gait process can bring new insights to gait data interpretation.

El análisis de datos de la marcha, está dando resultados mixtos con respecto a los cambios de locomoción asociados con el desarrollo de la esclerosis lateral amiotrófica (ELA). Se ha reivindicado la necesidad de nuevas herramientas de análisis de datos de la marcha. Aplicamos un enfoque de identificación no lineal al estudio de los datos de la marcha de pacientes sanos y con ELA, disponibles en Physionet.org. La auto-regresión no lineal no paramétrica del núcleo, permitió obtener realizaciones libres de ruido (NFR) que imitaban las trazas originales, aunque la correlación entre los datos originales y la NFR correspondiente fue menor entre los pacientes con ELA (p = 0,03), lo que sugiere una mayor contribución de las influencias estocásticas. La inspección visual de los retratos de fase, reconstruidos a partir de NFR mediante la aplicación del teorema de Takens, sugirió diferencias dinámicas entre los sujetos de control y los pacientes. Esto se confirmó cuando se cuantificaron las características del retrato de fase y se sometieron a un análisis discriminante (89 % de clasificaciones correctas; 24/28). La aplicación de una medida de disimilitud no lineal para comparar registros de marcha de pares, definida como una distancia entre funciones auto-regresivas no lineales subyacentes, permitió una excelente separación entre ALS y controles, a través de una escala multidimensional. El mapa de proyección obtenido sugirió claramente que las huellas de ALS se encuentran en un espacio dinámico más estrecho. Esto podría reflejar el hecho conocido sobre la degeneración neuronal que acompaña a la progresión de la ELA. Cuando se introdujeron los componentes principales de la matriz de disimilitud como variables predictoras, el análisis discriminante arrojó un 82% de clasificaciones correctas (23/28). En general, nuestros resultados sugieren que un enfoque de identificación no lineal, centrado en la caracterización de la dinámica del proceso de la marcha, puede aportar nuevos conocimientos a la interpretación de los datos de la marcha.

SPARK: SKILL BASED PERFORMANCE ASSESSMENT & RESEARCH BASED KNOWLEDGE- APPROACH FOR IMPROVING QUALITY OF HIGHER EDUCATION IN INDIA

There has to be an immediate adjustment in the process used to evaluate students at higher education institutions. In the majority of institutions, evaluation of students is still done at the conclusion of the academic year using a single standardised exam. Students are evaluated on the basis of this single test for their subject knowledge and conceptual clarity, and they are then given a mark sheet and certificate to use when applying for jobs. The Ratta method was given more weight in the Indian examination system, which is a fundamental aw that requires immediate remedy. Since complete educational objectives like comprehension, critical and independent thinking, creativity, problem-solving ability, reflective thinking, skill development, and application of information in real life are overlooked, the memorising of content takes precedence. Numerous educational committees have drawn attention to this flaw. Examinees' anxiety and fear are further exacerbated by the "Ratta system," and occasionally this anxiety results in the usage of unfair test practises. Cramming is encouraged as a way to gain better grades across the Indian examination system, which leads to a pressured environment. This paper focuses on the application of such an assessment approach of student which is free from rote memorization and emphasises conceptual understanding, skill development and knowledge gained through search and analysis.

A Prospective Observational Study on Outcomes of Single Stage Posterior Decompression and Fixation for Dorsolumbar Spine Tuberculosis / Estudo observacional prospectivo sobre os desfechos da descompressão posterior e fixação em estágio único na tuberculose da coluna dorsolombar

Abstract Objective To study the results of only posterior decompression and instrumentation in dorsal and dorsolumbar spine tuberculosis. Methods The patients (n = 30) who were included in this study had dorsal or dorsolumbar spine tuberculosis, with or without neurological deficit, and with or without deformity. All 30 patients were managed by only posterior approach decompression and instrumentation. We studied cases for correction and maintenance of deformity at dorsal and dorsolumbar spine, functional outcome by the Oswestry disability index (ODI) and visual analogue scale (VAS) scores, as well as neurological outcome by the Frankel grade. Results In the current series, 30 patients were operated with single stage posterior decompression and instrumentation, and showed significant improvement in neurological status and functional outcomes, which were accessed by the ODI score, VAS score, and Frankel grade. Conclusion The posterior (extracavitary) approach provides optimum access to the lateral and anterior aspects of the spinal cord for good decompression. It facilitates early mobilization and avoids problems of prolonged recumbency, provides better functional outcome, and significantly better sagittal plane kyphosis correction.

Resumo Objetivo Estudar os desfechos da descompressão posterior isolada e instrumentação na tuberculose da coluna dorsal e dorsolombar. Métodos Os pacientes (n = 30) incluídos neste estudo apresentavam tuberculose na coluna dorsal ou dorsolombar, acompanhada ou não por déficit neurológico e/ou deformidade. Todos os 30 pacientes foram tratados apenas por descompressão posterior e instrumentação. Estudamos a correção e manutenção da deformidade na coluna dorsal e dorsolombar, o desfecho funcional segundo o índice de deficiência de Oswestry (ODI) e a escala visual analógica (EVA); o desfecho neurológico foi estudado de acordo com a classificação de Frankel. Resultados Na atual série, 30 pacientes foram submetidos à descompressão posterior e instrumentação em estágio único e apresentaram melhora significativa no estado neurológico e desfecho funcional segundo os scores de ODI, EVA e classificação de Frankel. Conclusão A abordagem posterior (extracavitária) permite o acesso ideal aos aspectos laterais e anteriores da medula espinhal para uma boa descompressão. Facilita a mobilização precoce, evita problemas associados ao decúbito prolongado, proporciona melhor desfecho funcional e corrige a cifose no plano sagital de maneira significativamente melhor.

Techniques of Maxillary Sinus Floor Elevation

Posterior maxillary region is often limited for standard implant placement because of reduced residual vertical bone height. An elevation of the maxillary sinus floor is one option in solving this problem. This article describes the various surgical techniques that can be used to enter the sinus cavity, elevating the sinus membrane and placing the bone grafts for placement of dental implants in the resorbed posterior maxillary region.

El presente artículo resume la metodología y las conclusiones basadas en evidencia de la GPC para el manejo de la pancreatitis aguda en EsSalud.

This article summarizes the clinical practice guideline (CPG) for the management of acute pancreatitis in the Social Security of Peru (EsSalud), to provide evidence-based clinical recommendations for the management of acute pancreatitis in EsSalud. A guideline development group (GEG) was formed that included medical specialists and methodologists. The GEG formulated 7 clinical questions to be answered by this CPG. Systematic searches of systematic reviews and -when considered relevant-primary studies were carried out in PubMed during 2022. The evidence was selected to answer each of the clinical questions posed. The certainty of the evidence was assessed using the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) methodology. In periodic work meetings, the GEG used the GRADE methodology to review the evidence and formulate the recommendations, the points of good clinical practice, and the corresponding ow charts. Finally, the CPG was approved with Resolution No. 105-IETSI-ESSALUD-2022. This CPG addressed 7 clinical questions on buid therapy, start of enteral nutrition, analgesia, type of nutrition, antibiotic, and surgical treatment. Based on these questions, 8 recommendations (1 strong and 7 conditional), 13 BPCs, and 1 flowchart were formulated. This article summarizes the methodology and evidence-based conclusions of the CPG for the management of acute pancreatitis in EsSalud.

Application of laparoscopic ultrasound in retroperitoneal radical nephrectomy for renal cell carcinoma with Type II inferior vena cava tumor thrombectomy

Background: The aim of this study was to investigate the application value of laparoscopic ultrasound (LU) in retroperitoneal radical nephrectomy for renal cell carcinoma with Type II inferior vena cava tumor thrombectomy (RRN-RCC-TII-IVCTT). Methods: The clinical data (operative time, length of tumor thrombus, tumor length, intraoperative bleeding, clinical stage, histological type, residual tumor tissue, and postoperative follow-up) of 6 patients who underwent LU-guided RRN-RCC-TII-IVCTT were retrospectively analyzed, and the intraoperative experience of LU was also summarized. Results: All 6 patients recovered well with liver and kidney functions returning to normal, and no tumor recurrence, metastasis, or vena cava tumor thrombus. Conclusions: LU-guided RRN-RCC-TII-IVCTT is a feasible treatment option, which locates the tumor accurately by retroperitoneal approach and provides the additional benefit of reduced intraoperative bleeding and shortened operative time, also achieving the much sought-after goal of precision.

Perspectiva de Segunda Pessoa em Psicoterapia: as inovações fenomenológicas de Carl Rogers / Second Person Perspective in Psychotherapy: the phenomenological innovations of Carl Rogers

O estudo aponta e analisa as inovações clínicas e científicas de Carl Rogers introduzidas à psicoterapia. O foco está no papel da intersubjetividade, aqui entendida como perspectiva de segunda pessoa, mas sem desconsiderar as contribuições advindas das perspectivas de terceira (evidência experimental) e de primeira pessoa (vivência experiencial). O estudo argumenta que a relevância dada a intersubjetividade, a não-diretividade e a abertura à experiência testifica a confluência entre Rogers e o movimento fenomenológico. Tal confluência é realçada pela atenção ao exame dos fatos e fenômenos em múltiplas perspectivas, orientadas pela ética fenomenológica. Neste sentido, o grande equívoco das comparações entre a teoria de Rogers e a fenomenologia está em tomar como ponto de partida uma dada definição de fenomenologia, e não a vivência e a descrição de eventos fenomenais. Por fim, mostra-se como os estudos científicos de Rogers encontram ressonâncias em pesquisas fenomenológicas contemporâneas aplicadas à psicologia.

The study points out and analyzes the clinical and scientific innovations that Carl Rogers introduced to psychotherapy. The focus is on the role of intersubjectivity, here understood as a second-person perspective, but without disregarding the perspectives from third-person (experimental evidence) and first-person (experiential experience). The study argues that the relevance given to intersubjectivity, non-directivity, and openness to experience testifies to the confluence between Rogers and the phenomenological movement. Such confluence is enhanced by examining facts and phenomena from multiple perspectives, guided by phenomenological ethics. In this sense, the mistake in the comparisons between Rogers' theory and phenomenology lies in taking as a starting point given definition of phenomenology, and not the experience and description of phenomenal events. Finally, it shows how Rogers' scientific studies find resonances in contemporary phenomenological research applied to psychology.

Evidencia de la efectividad del uso de aparatología ortopédica prequirúrgica en pacientes con labio y paladar hendido: revisión sistemática / Evidence of the effectiveness of the use of presurgical orthopedic appliances in patients with cleft lip and palate: a systematic review

Resumen El objetivo de este artículo fue evaluar la evidencia sobre el uso de una aparatología ortopédica prequirúrgica (AOP) en pacientes con labio y paladar hendido. Se realizó una búsqueda en las siguientes bases de datos: Medline/PubMed, Google Scholar, Clinical Trails.gov, ProQuest y Web of Science. En la búsqueda, se encontraron 7.926 registros, de los cuales se analizaron 105 artículos de texto completo; de éstos se incluyeron 23 estudios en pacientes con uso de AOP, asi como su grupo control sin el uso del AOP, previo al mismo tipo de cirugía. Los aparatos más utilizados para la AOP en el manejo de LPH fueron: el paladar pasivo (Paladar de Hotz), el modelador nasolaveolar (NAM), aparato McNeil y por último el T-traction; los principales desenlaces evaluados fueron: la estética facial y apariencia nasal; la evaluación de medidas cefalométricas, de vías aéreas superiores, nasales, del ancho de la fisura y así como puntos de referencia anatómicos como la distancia inter-canina e inter-tuberosidad. Además, se encontraron estudios que evaluaron oclusión y la fonación. La evidencia de esta literatura sugiere que el uso de aparatos activos tiene un mejor efecto que la placa pasiva, en términos de estética facial y aproximación de los segmentos maxilares para el cierre de la fisura. Sin embargo, la heterogeneidad, el riesgo de sesgo y la baja calidad de los estudios no permite tener conclusiones sólidas.

Abstract This review article aimed to evaluate the evidence on the use of a presurgical orthopedic appliance (POP) in patients with cleft lip and palate. The search was conducted using Medline/PubMed, Scholar Google, Clinical Trails, ProQuest, Scopus, and Web of Science databases. During the search, 7,926 records were found, of which 105 full-text articles were analyzed, and 23 studies included analysis in patients with the use of POP, and their control groups without the use of POP prior to the same type of surgery. The devices most used for POP in the management of LPH were: the passive palate (Hotz palate), the nasolaveolar moulding (NAM), the McNeil device, and finally, the T-traction. The primary outcomes evaluated were: facial aesthetics and nasal appearance; the evaluation of cephalometric measurements, upper airways, nasal fissure width, as well as anatomical references such as inter-canine and intertuberosity distances. In addition, studies that evaluated occlusion and phonation were found. The evidence from this literature suggests that the use of active appliances had a better effect than passive appliances in terms of facial aesthetics and approximation of the maxillary segments for the closure of the fissure. However, the heterogeneity, the risk of bias, and the low quality of the studies do not allow to state firm conclusions.
