Acupuncture for chronic prostatitis/chronic pelvic pain syndrome: a randomized controlled trial / 中国针灸

OBJECTIVE@#To observe the short-term efficacy, long-term efficacy and safety of acupuncture for chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS).@*METHODS@#Forty-two patients with CP/CPPS were randomly divided into an acupuncture group (21 cases, 1 case dropped off) and a sham acupuncture group (21 cases). The patients in the acupuncture group were treated with acupuncture at bilateral Zhongliao (BL 33), Huiyang (BL 35), Shenshu (BL 23) and Sanyinjiao (SP 6); the needling depth of Zhongliao (BL 33) and Huiyang (BL 35) was 60 to 80 mm, while Shenshu (BL 23) and Sanyinjiao (SP 6) was directly punctured of 30 mm. The patients in the sham acupuncture group were treated with acupuncture at non-acupoints, including points 2 cm next to Shenshu (BL 23), Zhongliao (BL 33) and Huiyang (BL 35), and the midpoint of the connecting line between the spleen meridian and the kidney meridian. All the non-acupoints were treated with directly puncture of 2 to 3 mm. The needles were left for 30 min in both groups, once every other day in the first four weeks, three times a week, and twice a week in the next four weeks, totally 20 treatments. Before treatment, after treatment and in follow-up of 24 weeks after treatment completion, the National Institutes of Health-chronic prostatitis symptom index (NIH-CPSI) score and urinary flow rate were observed in both groups; the clinical efficacy and safety were evaluated.@*RESULTS@#Compared with those before treatment, the pain and discomfort scores, urination symptoms scores, quality of life scores and total scores of NIH-CPSI in both groups were reduced after treatment in the two groups (P<0.01), while each item score and total score of NIH-CPSI in the acupuncture group were reduced in follow-up (P<0.01, P<0.05). After treatment and in follow-up, each item score and total score of NIH-CPSI in the acupuncture group were lower than those in the sham acupuncture group (P<0.05, P<0.01). After treatment, the maximum and average urinary flow rates in the acupuncture group were higher than those before treatment (P<0.05), and the average urinary flow rate in the acupuncture group was higher than that in the sham acupuncture group (P<0.05). The total effective rate was 75.0% (15/20) in the acupuncture group, which was higher than 42.9% (9/21) in the sham acupuncture group (P<0.05). No significant adverse reactions were observed in the two groups, and there was no significant difference in the incidence of adverse reactions between the two groups (P>0.05).@*CONCLUSION@#Acupuncture could effectively alleviate the clinical symptoms, improve quality of life, and has a sustained, safe and reliable therapeutic effect in patients with CP/CPPS.

Clinical experience of REcanalisation and balloon-oriented puncture for Re-insertion of long- term dialysis catheter in nonpatent central veins / 中华肝脏病杂志

It is difficult to insert long-term dialysis catheters after severe stenosis or occlusion of the internal jugular vein and innominate vein. We used REcanalisation and balloon-oriented puncture for Re-insertion of dialysis catheter in nonpatent central veins (REBORN) in seven patients with severe central venous lesions, and all patients were inserted with long-term dialysis catheters successfully. None had severe complications such as pneumothorax, hemothorax, or pulmonary embolism during operation. All catheters functioned well after postoperative follow-up of 2 months. REBORN provides a novel approach to establish difficult dialysis pathways.

Application of different puncture techniques to inject bone cement in osteoporotic vertebral compression fractures / 中国骨伤

OBJECTIVE@#To study the application of different puncture techniques to inject bone cement in osteoporotic vertebral compression fractures (OVCFs).@*METHODS@#The clinical data of 282 patients with OVCFs treated from January 2017 to December 2019 were collected for a retrospective study. According to the surgical plan the patients were divided into group A and B, with 141 cases in each group. In group A, extreme lateral puncture was used to inject bone cement through unilateral puncture and bilateral puncture. In group B, bone cement was injected through unilateral pedicle puncture through pedicle approach. The operation status(operation time, radiation exposure time, bone cement injection volume, hospital stay) and complications were observed between two groups. Before operation and 6, 12 months after operation, the pain mediators such as serotonin 5-hydroxytryptamine (5-HT), prostaglandin E2(PGE2), substance P(SP) were compared, bone mineral density, anatomical parameters of the injured vertebrae (height of the anterior edge of the vertebral body, height of the posterior edge of the vertebral body, Cobb angle), visual analogue scale (VAS) and Oswestry disability index (ODI) were evaluated between two groups.@*RESULTS@#There were no significant difference in operation time, radiation exposure time, hospital stay between two groups (P>0.05). The amount of bone cement injected in group A was greater than that in group B (P<0.05). The serum 5-HT, SP and PGE2 levels of group A were lower than those of group B at 12 months after operation (P<0.05). The height of anterior edge and height of the posterior edge of vertebral body in group A were greater than those of group B at 12 months after operation, Cobb angle of group A was smaller than that of group B, VAS and ODI were lower than those of group B(P<0.05). There was no significant difference in bone mineral density between two groups at 6 and 12 months postoperatively(P<0.05). There was no significant difference between two groups in postoperative complications (P>0.05).@*CONCLUSION@#Compared with unilateral puncture of the pedicle approach, unilateral puncture and bilateral cement injection technique is more conducive to the recovery of the injured vertebral anatomy and function, and do not prolong operation time, radiation exposure time, hospital stay, nor do increase the risk of nerve damage and bone cement leakage, and postoperative bone metabolism and bone mineral density are improved well, which is a safe and reliable surgical method for the treatment of OVCFs.

Epidural hydroxyethyl starch ameliorating postdural puncture headache after accidental dural puncture / 中华医学杂志(英文版)

BACKGROUND@#No convincing modalities have been shown to completely prevent postdural puncture headache (PDPH) after accidental dural puncture (ADP) during obstetric epidural procedures. We aimed to evaluate the role of epidural administration of hydroxyethyl starch (HES) in preventing PDPH following ADP, regarding the prophylactic efficacy and side effects.@*METHODS@#Between January 2019 and February 2021, patients with a recognized ADP during epidural procedures for labor or cesarean delivery were retrospectively reviewed to evaluate the prophylactic strategies for the development of PDPH at a single tertiary hospital. The development of PDPH, severity and duration of headache, adverse events associated with prophylactic strategies, and hospital length of stay postpartum were reported.@*RESULTS@#A total of 105 patients experiencing ADP received a re-sited epidural catheter. For PDPH prophylaxis, 46 patients solely received epidural analgesia, 25 patients were administered epidural HES on epidural analgesia, and 34 patients received two doses of epidural HES on and after epidural analgesia, respectively. A significant difference was observed in the incidence of PDPH across the groups (epidural analgesia alone, 31 [67.4%]; HES-Epidural analgesia, ten [40.0%]; HES-Epidural analgesia-HES, five [14.7%]; P <0.001). No neurologic deficits, including paresthesias and motor deficits related to prophylactic strategies, were reported from at least 2 months to up to more than 2 years after delivery. An overall backache rate related to HES administration was 10%. The multivariable regression analysis revealed that the HES-Epidural analgesia-HES strategy was significantly associated with reduced risk of PDPH following ADP (OR = 0.030, 95% confidence interval: 0.006-0.143; P < 0.001).@*CONCLUSIONS@#The incorporated prophylactic strategy was associated with a great decrease in the risk of PDPH following obstetric ADP. This strategy consisted of re-siting an epidural catheter with continuous epidural analgesia and two doses of epidural HES, respectively, on and after epidural analgesia. The efficacy and safety profiles of this strategy have to be investigated further.

Estrategias no farmacológicas como adyuvantes para manejo del dolor agudo por punción en pediatría / Non-pharmacological strategies as adjuvants in needle associated acute pain management in pediatrics

El dolor en pediatría es un problema de salud pública que afecta al 78 % de pacientes hospitalizados y está frecuentemente asociado a punciones, por lo que es necesario un control rápido y efectivo. Existen en la actualidad estrategias psicológicas y físicas de estimulación sensorial para abordarlo. Se pretende describir el uso de estas como coadyuvantes en el manejo del dolor agudo por punción en pediatría. Se realizó una revisión narrativa de artículos originales y revisiones bibliográficas. El mecanismo del dolor involucra a las fibras C y a las fibras Aδ, que responden al dolor por punción. Entre las estrategias innovadoras se encuentra el dispositivo Buzzy®, que actúa mediante la teoría de compuerta del dolor, desviando la atención del dolor hacia un estímulo sensorial placentero (frío y vibración) que disminuye la intensidad en comparación con anestésicos locales (p < 0,001); así mismo, la realidad virtual desvía la atención del niño hacia un estímulo placentero, visual o auditivo, creando un ambiente tridimensional y produciendo analgesia por distracción en comparación al control (p < 0,05). El uso de estrategias no farmacológicas como coadyuvantes para el manejo de dolor por punción son efectivas para disminuir el dolor en el paciente pediátrico, así como el estrés y la ansiedad, tanto en los padres como en el personal de salud

Pediatric pain is a public healthcare problem present in 78 % of hospitalized patients and it is frequently associated to needles. Fast and effective controls are needed, therefore, sensory stimulation and psychological strategies have been developed. The aim of this study was to describe the use of non-pharmacological strategies as adjuvants in needle associated children pain management. A review was made searching through original articles and other reviews. Pain mechanism involves C fibers and Aδ fibers, which respond to short term needle pain. Buzzy® device is among the innovative physical strategies to relieve pain, which acts according to the pain threshold theory, diverting attention from pain to a pleasurable sensory stimulus (cold and vibration) decreasing its intensity when compared to topical anesthesia (p < 0,001). Meanwhile psychological strategies such as virtual reality divert the child's attention to a pleasant visual and auditory stimulus. It creates a tridimensional environment with an electronic device, decreasing pain while distracting the child when compared to the control group (p < 0,05). The use of innovative non-pharmacological strategies as adjuvants for needle pain management is effective decreasing children pain and reducing stress and anxiety in parents and healthcare workers

A method of lung puncture path planning based on multi-level constraint / 生物医学工程学杂志

Percutaneous pulmonary puncture guided by computed tomography (CT) is one of the most effective tools for obtaining lung tissue and diagnosing lung cancer. Path planning is an important procedure to avoid puncture complications and reduce patient pain and puncture mortality. In this work, a path planning method for lung puncture is proposed based on multi-level constraints. A digital model of the chest is firstly established using patient's CT image. A Fibonacci lattice sampling is secondly conducted on an ideal sphere centered on the tumor lesion in order to obtain a set of candidate paths. Finally, by considering clinical puncture guidelines, an optimal path can be obtained by a proposed multi-level constraint strategy, which is combined with oriented bounding box tree (OBBTree) algorithm and Pareto optimization algorithm. Results of simulation experiments demonstrated the effectiveness of the proposed method, which has good performance for avoiding physical and physiological barriers. Hence, the method could be used as an aid for physicians to select the puncture path.

Abdominal puncture drainage alleviates severe acute pancreatitis in rats by activating Nrf-2/HO-1 pathway and promoting autophagy / 南方医科大学学报

OBJECTIVE@#To assess the effect of early abdominal puncture drainage (APD) on autophagy and Nrf-2/HO-1 pathway in rats with severe acute pancreatitis (SAP) and explore the possibile mechanism.@*METHODS@#Thirty-two male SD rats were randomly divided into sham-operated (SO) group, SAP group with retrograde injection of 4% sodium taurocholate, APD group with insertion of a drainage tube into the lower right abdomen after SAP induction, and APD + ZnPP group with intraperitoneal injection of 30 mg/kg ZnPP 12 h before APD modeling. Blood samples were collected from the rats 12 h after modeling for analysis of amylase and lipase levels and serum inflammatory factors. The pathological changes of the pancreatic tissue were observed with HE staining. Oxidative stress in the pancreatic tissue was detected with colorimetry, and sub-organelle structure and autophagy in pancreatic acinar cells were observed by transmission electron microscopy. The expressions of autophagy-related proteins and Nrf-2/HO-1 pathway were detected using RT-PCR and Western blotting.@*RESULTS@#Compared with those in SAP group, the rats with APD treatment showed significantly alleviated pathologies in the pancreas, reduced serum levels of lipase, amylase and inflammatory factors, lowered levels of oxidative stress, and activated expressions of Nrf-2/HO-1 pathway in the pancreas. The ameliorating effect of ADP was significantly inhibited by ZnPP treatment before modeling. APD obviously reversed mitochondrial and endoplasmic reticulum damages and p62 accumulation induced by SAP.@*CONCLUSION@#APD treatment can suppress oxidative stress and repair impaired autophagy in rats with SAP by activating the Nrf-2/HO-1 pathway, thereby reducing the severity of SAP.

ABSTRACT Objective to describe the elaboration process and implementation strategies of a bundle for pain relief during arterial puncture in hospitalized infants. Methods a qualitative approach study carried out in a neonatal intensive care unit, through conversation circles held with the Nursing team. Data collection took place from February to May 2019. Results the meetings led to the elaboration of a bundle consisting of four items, in a playful format, and which should be attached to the incubator prior to the puncture. Conclusion and Implications for the practice The process stimulated critical reflection about the practice itself and the professionals mentioned use of the bundle as something feasible within the unit, through planning for its inclusion in the care routine. The study is pioneering and presents an innovative character when using the bundle to relieve a multifaceted issue such as pain in the neonatal period. Despite having been specifically created for arterial puncture, it can also be applied in other procedures that potentially generate acute pain, as the main focus is always to minimize the discomfort felt by the infant.

Avaliação ultrassonográfica de variações anatômicas entre vasos femorais realizada por estudantes de medicina / Ultrasonographic evaluation of anatomical variations in femoral vessels done by medical students

Introdução: A punção venosa central é um procedimento médico tradicionalmente realizado seguindo os marcadores anatômicos como referência para atingir o vaso, às cegas. No entanto, nem sempre o sucesso nessa técnica é alcançado, fato que se deve principalmente às variações anatômicas. A ultrassonografia point of care (US-POC) é utilizada para auxiliar a cateterização central por visualização direta do vaso, aumentando a segurança do procedimento. Objetivo: Avaliar a prevalência das variações anatômicas de vasos femorais através da utilização da US-POC por estudantes de medicina submetidos a curto período de treinamento. Material e Métodos: Cinco estudantes de medicina, sem experiência prévia em US-POC, foram submetidos a oito horas de treinamento teórico-prático. Foram avaliados os vasos femorais de cem voluntários. Resultados: A veia femoral direita foi encontrada mais frequentemente na posição medial (43%) em relação à artéria femoral direita. À esquerda, a posição posteromedial foi a mais observada (45%).Conclusão: A técnica tradicional de punção de acesso central se baseia em marcadores anatômicos e não leva em consideração as variações anatômicas existentes. Um treinamento de curto período para uso da US-POC é capaz de capacitar o profissional para reconhecer o posicionamento real dos vasos e evitar punções inadvertidas.

Introduction: Central vein puncture is a medical procedure traditionally done following anatomical landmarks as a reference to successfully achieving the vessel. However, this traditional technique is commonly unsuccessful due to anatomical variations that may be found. Point of care ultrasonography (POC-US) is used to assist central catheterization by directly visualizing the vessel, increasing procedure security and minimizing risks. Objective: Evaluate anatomical variations prevalence in femoral vessels, utilizing POC-US, done by medical students submitted to a short period of time training in ultrasonography. Material and Methods: Five medical students, without previous experience on the use of ultrasonography, were submitted to an eight-hour theorical practical training in POC-US. The students evaluated one hundred femoral vessels of volunteers. Results: The right limb femoral vein was found more frequently in the medial position (43%) in comparison to the right limb femoral artery. On the left limb, the posteromedial position was the most found (45%). Conclusion: The insertion of a central catheter following the traditional technique is based on anatomical landmarks, and does not take into account existing anatomical variations. With a short period of training, POC-US is capable of qualifying professionals to acknowledge the real location of the vessel and avoid inadvertent punctures and complications.

Preferred display size and visual distance for ultrasound-guided radial artery cannulation / Tamaño preferido de la imagen en pantalla y distancia visual para la canalización de la arteria radial guiada por ecografía

Abstract Introduction: In-line positioning of an ultrasound image provides higher success rates and less time to completion for radial arterial cannulation. But preferable size and distance of ultrasound display has not been previously discussed. Objective: To assess the ideal visual distance and display size when using a smart phone or tablet as the ultrasound image display. Methods: Four smart phones or tablets were used as ultrasound displays in six different configurations in a simulated radial artery puncture. In a questionnaire, 116 anaesthesiologists working in Ibaraki Prefecture, Japan, were asked which of the six configurations was preferable for radial artery cannulation. Results: Sixty anaesthesiologists answered the questionnaire. About half (53%) preferred the smaller display (4- or 5.5-inch) fixed at a distance of 30 to 40 cm, and most of the rest (44%) preferred the larger display (7.9- or 9.7-inch) placed posterior to the probe with a visual distance of 45 to 60 cm. Conclusions: Among the anaesthesiologists, the preferable size and visual distance for ultrasound-guided radial artery cannulation varied using a smart phone or tablet for in-line display.

Resumen Introducción: El posicionamiento en línea con una imagen ecográfica permite mayores tasas de éxito y reduce el tiempo para realizar la canalización de la arteria radial. Sin embargo, no se ha hablado sobre cuál es el tamaño y la distancia preferibles para la imagen en pantalla. Objetivo: Evaluar la distancia visual y el tamaño de la imagen en pantalla cuando se utiliza un teléfono inteligente o una tableta para visualizar la imagen ecográfica. Métodos: Se utilizaron cuatro teléfonos inteligentes o tabletas como pantalla para visualizar las imágenes ecográficas en seis configuraciones distintas, en una simulación de la canalización de la arteria radial. Mediante un cuestionario se preguntó a 116 anestesiólogos que trabajan para la Prefectura de Ibaraki, Japón, cuál de las seis configuraciones era preferible para la canalización de la arteria radial. Resultados: Sesenta anestesiólogos respondieron el cuestionario. Aproximadamente la mitad (53%) prefirieron la imagen más pequeña (4 o 5,5 pulgadas), fija a una distancia de 30 a 40 cm, y la mayoría de los otros (44%) prefirieron la imagen más grande (7,9- o 9,7 pulgadas), colocada en la parte posterior al transductor, con una distancia visual de 45 a 60 cm. Conclusiones: Entre los anestesiólogos, el tamaño preferido y la distancia visual para la canalización de la arteria radial guiada por ecografía, varió utilizando un teléfono inteligente o una tableta para su visualización en línea.

Nuestra conducta frente a los quistes hidatídicos primarios del páncreas / Our experience with pancreatic primary cysts

Antecedentes: Los quistes hidatídicos primarios pancreáticos son raros por no decir excepcional, siendo en las grandes series su incidencia apenas entre el 0,2 % al 0,3%. Lugar de Aplicación: Servicio de Cirugía General "Pablo Luis Mirizzi" del Hospital Nacional de Clínicas, Sanatorio Allende y Clínica Privada Caraffa de Córdoba. Diseño: Cooperativo, retrospectivo. Material y Método: Entre diciembre de 2000 y diciembre del 2019 han sido tratados quirúrgicamente 9 pacientes con hidatidosis primaria de páncreas, siendo 5 del sexo masculino y los cuatro restantes del sexo femenino, con una edad promedio de 39,4 años. En relación con la clínica, todos los pacientes tenían dolor abdominal, acompañado de vómitos, distensión abdominal y fiebre. En tres presentaban una masa abdominal palpable. A todos se les solicito laboratorio y pruebas de hidatidosis, destacándose en 6 de los 9 pacientes dieron positivo. Resultados: Se estudiaron a todos los pacientes con una ecografía abdominal, TC de abdomen y en un paciente una CPRMN más RMN de abdomen. Se realizaron previamente el tratamiento con abendazol antes del tratamiento quirúrgico en todos los casos. En relación con el tratamiento quirúrgico, se llevó a cabo el destechamiento y drenaje del quiste con la técnica de Mabit-Lagrot en 6 oportunidades y en 3 con la Técnica de Goinard. Conclusión: La localización de los quistes hidatídicos en el páncreas es rara. El diagnóstico se basa fundamentalmente en los estudios por imágenes, además si se correlacionan con la epidemiología y la serología hidatídica positiva. El tratamiento del quiste hidatídico de páncreas es quirúrgico.

Background: Pancreatic primary hydatic cysts are rare not to say exceptional, with their incidence in large series being only 0.2% to 0.3%. Setting: General Surgery Service "Pablo Luis Mirizzi" of the National Hospital of Clinics, Allende Sanatorium and Caraffa Clinic of Córdoba. Design: Retrospective and cooperative. Methods: Between December 2000 and December 2019, 9 patients with primary pancreatic hydatic have been treated surgically, with 5 of the male sex and the remaining four of the female sex, with an average age of 39.4 years. In relation to the clinic, all patients had abdominal pain, accompanied by vomiting, bloating and fever. In three they had a palpable abdominal mass. All were asked for laboratory and hydatic tests, highlighting in 6 of the 9 patients tested positive. Results: All patients with abdominal ultrasound, abdominal CT and a patient were studied for CPRMN plus MRI of the abdomen. Abendazole was previously treated prior to surgical treatment in all cases. In relation to surgical treatment, the traditional unroofing and drainage of the cyst was carried out with the Mabit-Lagrot technique in 6 opportunities and in 3 with the Goinard Technique. Conclusions: The location of hydatic cysts in the pancreas is rare. Diagnosis is based primarily on imaging studies, in addition if they correlate with epidemiology and positive hydatic serology. Treatment of the pancreas hydatic cyst is surgical
