ABSTRACT

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

ABSTRACT

The paper introduces professor ZHUANG Li-xing's clinical experience in treatment of intra-uterine residue and lochia after drug abortion. Professor ZHUANG believes that this disorder is related to "dysfunction of the thoroughfare vessel and the conception vessel, qi deficiency and blood stagnation, and retention of turbid qi in the uterus" in pathogenesis. The treating principle should focus on "regulating the functions of the thoroughfare vessel and the conception vessel, tonifying qi and eliminating stasis, as well as promoting qi movement". Besides Hegu (LI 4) and Sanyinjiao (SP 6), the acupoints are added from the conception vessel. The Daoqi Tongjing needling technique (the specific technique for directing qi and preserving essence) is exerted flexibly instead of traditional reinforcing and reducing technique of acupuncture to tonify qi and remove stasis.

ABSTRACT

Professor WU Lian-zhong's experience in treating spasmodic torticollis by Kaiqiao Shunjin method (resuscitation and regulating muscle) is summarized in this paper. The pathogenesis of spasmodic torticollis is the occluded brain orifices and delirium, qi disorder of meridian tendons, specifically divided into five categories: damp-heat, liver-yang hyperactivity, liver-kidney yin deficiency, deficiency of the governor vessel, excess of the governor vessel. The treatment should be based on the symptoms and the root causes, the symptoms should be the main treatment, and the root cause should be treated based on syndrome differentiation. The main treatment is Kaiqiao Shunjin method (resuscitation and regulating muscle), and to take the chief (five heart acupoints-Shuigou [GV 26], Laogong [PC 8], Yongquan [KI 1]), deputy (Yintang [GV 24+], Shangxing [GV 23] through Baihui [GV 20], Ximen [PC 4]), assistant (Fenglong [ST 40], Lianquan [CV 23], combined with tongue needle prick), envoy (Hanyan [GB 4]) as the basic main acupoints, at the same time cooperate with local acupoints to remove knots and accumulation. Finally, syndrome differentiation is adopted to dredge meridians and disperse knots, regulate the governor vessel, and nourish yin and dispel wind.

ABSTRACT

OBJECTIVE@#To observe the clinical efficacy of micro needle knife therapy on cervical vertigo.@*METHODS@#A total of 300 patients with cervical vertigo treated from January 1, 2017 to December 31, 2019 were randomly divided into micro needle knife group (96 cases, 4 cases falling off), traditional acupuncture group (96 cases, 4 cases falling off) and oral drug group(95 cases, 5 cases falling off). The micro needle knife group was treated with micro needle knife in the local upper cervical segment once every other day for 7 times; the traditional acupuncture group was treated with traditional acupuncture once a day for 2 weeks;the oral drug group was given Merislon (betahistine mesilate tablets) orally, 6 mg each time, 3 times a day for 2 weeks. The patients were followed up before treatment, at the end of treatment and 3 months after treatment. The dizziness handicap inventory(DHI) was observed and the curative effect was evaluated according to the DHI score.@*RESULTS@#At the end of the course of treatment and 3 months after the treatment, DHI scores of the three groups were significantly lower than those before treatment(P<0.01), and the DHI scores of micro needle knife group were lower than those of traditional acupuncture group and oral drug group at the same time point after treatment (P<0.01). There was no statistically significant difference in DHI scores between traditional acupuncture group and oral drug group at the same time after treatment(P< 0.05). The curative effect was evaluated according to DHI score:in micro needle knife group, 50 cases were cured, 28 cases were markedly effective, 14 cases were improved, the total effective rate was 95.83%; in traditional acupuncture group, 28 cases were cured, 26 cases were markedly effective, and 24 cases were improved, with the total effective rate of 81.25%;in oral drug group, 18 cases were cured, 20 cases were markedly effective, and 28 cases were improved, with the total effective rate of 69.47%. The total effective rate of micro needle knife group was significantly higher than that of other two groups (χ2=45.956, P=0.000). Among the cured patients in the three groups, the time required in the micro needle knife group was significantly less than that in the traditional acupuncture group and oral drug group(F=18.796, P=0.000).@*CONCLUSION@#Micro needle knife loosening atlantoaxial soft tissue has obvious curative effect on cervical vertigo which clinical cure rate, effective rate and treatment time required for cured patients are better than traditional acupuncture and oral drug.

ABSTRACT

Professor JIAO Mian-zhai 's academic characteristics and needling essentials in acupuncture field are introduced in the paper. Professor JIAO integrated martial arts and qigong with acupuncture needling technique, and then created his own "yunzhang bafa" (eight kinds of palm movement and qi training method) and modified the basic skills for finger strength practice and needling techniques. On the base of the needling techniques exerted by both hands, he developed a set of "JIAO 's needling techniques", including the manipulations of needle insertion and withdrawal. He proposed that the compound needling techniques for reinforcing and reducing should be cooperated with the physician's respiratory rhythm. Besides, he clarified the operation timing of reinforcing and reducing techniques to ensure the full play to the curative effect of acupuncture.

ABSTRACT

This device is an auxiliary device with reasonable design for placebo acupuncture research, so as to make double-blind placebo acupuncture control possible. This new auxiliary acupuncture device includes an acupuncture device and a placebo acupuncture device with exactly the same appearance. Both of them are composed of a hemispherical base and a telescopic tube. Through the rotation of the telescopic tube in the notch of the base, the insertion angle of needles can be adjusted from 15 degrees to 165 degrees. The operation of twisting and lifting and inserting can be carried out through the horizontal rotation and vertical sliding of the telescopic tube. A silicone needle pad is arranged in the base, which can simulate the blocking feeling of skin and muscle during needle insertion. The bottom of the base is attached with hydrogel, which has good fixity. The auxiliary device is applicable to multiple parts of the human body and can effectively reduce the risk of unblinding.

ABSTRACT

Professor ZHANG Shan-chen's clinical experience and academic thoughts in the field of acupuncture are summarized. Professor ZHANG stresses on theoretical exploration and has written Zhenjiu Jiayijing Shuxue Chongji, published a series of articles on textual research and expounded the nomenclature of acupoints. He believes that clinical practice should be guided by theory and the comprehensive syndrome differentiation be emphasized. Hence, a holistic idea should be cultivated, in which, the human body is considered as an organic whole and should be adaptive to the nature. Based on the theory above, the diagnosis can be determined and the effective treatment be received. He suggests selecting few acupoints, identifying the deficiency from the excess so as to determine the reinforcing or replenishing method and exerting appropriate needling manipulation. Additionally, the response should be enhanced on the identification of deqi after needle insertion. Moreover, a great consideration is laid on the clinical trial and application of moxibustion, which is complemented with acupuncture technique each other and mutually conductive to the clinical effect.

ABSTRACT

OBJECTIVE@#To observe the effect of thumb-tack needles based on "Biaoben acupoint compatibility" on sequela symptoms, mental state and pulmonary ventilation function in patients with coronavirus disease 2019 (COVID-19) during recovery period.@*METHODS@#Fifty cases of COVID-19 during recovery period were randomly divided into an observation group and a control group, 25 cases in each group. The patients in the observation group were treated with thumb-tack needles at Guanyuan (CV 4), Zusanli (ST 36) and Taiyuan (LU 9). The patients in the control group were treated with sham thumb-tack needles at identical acupoints as the observation group. The treatment in the two groups was given once a day, 7-day treatment was taken as a course of treatment, and totally two courses of treatment were given. The TCM symptom score, Hamilton anxiety scale (HAMA) score, Hamilton depression scale (HAMD) score, pulmonary function (forced vital capacity [FVC], forced expiratory volume in the first second [FEV1], peak expiratory flow [PEF]), the severity of pulmonary ventilation dysfunction and pulmonary imaging changes in the two groups were compared before and after treatment.@*RESULTS@#Compared before treatment, the total scores and each item scores of TCM symptom scale, HAMA scores and HAMD scores in the two groups were reduced after treatment (P<0.05). Except for the symptom scores of dry throat and dry stool, the total score and each item score of TCM symptom scale, HAMA score and HAMD score in the observation group were lower than those in the control group (P<0.05). Compared before treatment, FVC, FEV1 and PEF in the two groups were increased after treatment (P<0.05), and those in the observation group were higher than the control group (P<0.05). The severity of pulmonary ventilation dysfunction in the two groups was reduced after treatment (P<0.05), and the severity in the observation group was better than that in the control group (P<0.05). After treatment, the lung shadow area in the two groups was decreased (P<0.05), and that in the observation group was smaller than the control group (P<0.05). The improvement of imaging change in the observation group was better than that in the control group (P<0.05).@*CONCLUSION@#The thumb-tack needles based on "Biaoben acupoint compatibility" could significantly reduce the sequela symptoms, anxiety and depression in patients with COVID-19 during recovery stage, and improve the pulmonary ventilation function.

ABSTRACT

Through reviewing acupuncture technique in various editions of the state-compiled teaching material of Acupuncture and Moxibustion, the hierarchical structure, definitions, and variations of acupuncture manipulation were collected, the theory of contemporary acupuncture manipulation as well as its application characteristics were explored. In the perspective of the hierarchical structure, acupuncture technique with filiform needle is predominated. It is implied in the description of the definition of acupuncture technique that the devices of acupuncture have been developed from single form to multivariant one and the stimulation regions have no longer limited to acupoints. The types of acupuncture manipulations have been enriched gradually during the development of teaching materials. But a part of acupuncture manipulation have been deleted from the knowledge hierarchy of acupuncture technique in textbooks. Acupuncture and Moxibustion is comprehensive and normative, which is important in the inheritance and application of the theory of acupuncture and moxibustion. However, it has to some extent restricted the diversified development of knowledge on acupuncture manipulation.

ABSTRACT

Introdução: O tipo de agulha e fluxo de irrigação é importante para a limpeza adequada no terço apical do canal radicular. Objetivo: Avaliar a influência do tipo de agulha e fluxo de irrigação na limpeza do canal radicular e canais laterais simulados e na extrusão apical do irrigante. Métodos: Trinta e dois dentes de resina foram utiliza- dos. Após a instrumentação do canal radicular, foram feitos quatro canais laterais a 2 e 7 mm do ápice. Os canais radiculares foram preenchidos com solução de contraste. Os canais foram irrigados com dois tipos de agulha, 29G e 31G, com diferentes designs (abertura lateral e apical) e dois fluxos (2 ou 5 mL/min), a 1 mm aquém do comprimento de trabalho. O volume da solução de contraste nos canais principal e laterais após irrigação e a extrusão apical do irrigante (mm3 ) foi avaliado por micro-CT, em comparação com a análise inicial. Os dados em porcentagem foram analisados pelos testes ANOVA e Tukey (α=0,05). Resultados: não houve diferença entre os protocolos de irrigação para limpeza da solução de contraste. Maior volume de extrusão apical com agulha 29G com abertura apical e 5 mL/min foi observado, em comparação ao mesmo tipo de agulha e 2 mL/min (p<0,05). Conclusão: Todos os protocolos de irrigação foram associados à limpeza dos canais radiculares. Maior extrusão apical foi observada com agulha 29G ­ abertura apical com maior fluxo de irrigação (5 mL/min). Implicações clínicas: Irrigação endodôntica com agulha com abertura apical e maior fluxo da solução pode favorecer a extrusão dos irrigantes para os tecidos periapicais (AU).


Introduction: needle and irrigation flow rate are important for proper cleaning of the root canal. Aim: to evaluate the influence of type of needle and irrigation flow rate on cleaning of root canal and simulated lateral canals and the apical extrusion of irrigant. Methods: Thirty-two resin teeth were used. After root canal instrumentation, four lateral canals were made at 2 and 7 mm from the apex. Root canals were filled with contrast solution. The root canals were irrigated with two types of needle, 29G and 31G, with different designs (side and apical opening) and two flow rates (2 or 5 mL/min), at 1 mm short of the working length. The volume of the contrast solution in the main and lateral canals after irrigation and apical extrusion of the irrigant (mm3) were evaluated by Micro-CT, in comparison with the initial analysis. Data in percentage were analyzed by ANOVA and Tukeys tests (α = 0.05). Results: no difference among the irrigation protocols for contrast solution cleaning was observed. Higher volume of apical extrusion using needle 29G-apical opening and 5 mL/min in comparison with the same type of needle and 2 mL/min was observed (p < 0.05). Conclusion: all irrigation protocols were associated with root canals cleaning. Greater apical extrusion was observed for needle 29G-apical opening with higher irrigation flow rate (5 mL/min). Clinical implications: endodontic irrigation using a needle with apical opening and higher flow rate of solution may favor extrusion of irrigant to the periapical tissues (AU).

ABSTRACT

ABSTRACT Objective: To evaluate the efficacy of pre-cooling and the use of higher gauged needles in reducing pain during local anesthetic infiltration. Material and Methods: We conducted a split-mouth randomized controlled trial among 70 patients who require bilateral maxillary local anesthetic (LA) injections for dental treatment. After applying the topical anesthetic, each participant received four local anesthetic injections, two on buccal and two palatal sides. At each visit, the participants received one buccal and one palatal infiltration based on the randomization. On the buccal aspect, participants received LA with a 26G needle injection on one side (control) and a 31G needle (test) on the contralateral side. On the Palatal aspect, participants either received LA with a 31G needle on one side (control). In contrast, the opposite side was preceded by topical ice application (iced cotton swab) before LA with a 31G needle (test). Both the visits were spaced with a gap of 7-10 days based on the participants' feasibility. Participants were asked to rate the pain on a visual analog scale independently for buccal and palatal LA injections. Results: On the Buccal aspect, the mean pain scores were 2.74 ± 1.26 and 2.11 ± 1.26 for control and test groups, respectively (p=0.002). On the Palatal aspect, the mean pain scores were 4.14 ± 1.49 and 4.3 ± 1.80 for control and test groups, respectively (p=0.295). Conclusion: Significant lower pain scores were reported with higher gauge needles (31G) when compared to traditional (26G) needles on the buccal aspect. No significant difference was seen with pre-cooling the injection site on the palatal aspect when used with higher gauged needles (31G).

ABSTRACT

La presencia de elementos extraños dentro del canal raquídeo es infrecuente y no hay claro consenso respecto de su tratamiento. Las publicaciones sobre fragmentos de proyectil de arma de fuego intracanal recomiendan la exéresis de los fragmentos ante la posibilidad de migración, sobre todo, cuando están en una zona próxima al cono medular. Se debería proceder del mismo modo ante una aguja dentro del canal espinal. Presentamos a una paciente con dolor radicular invalidante provocado por un fragmento de aguja dentro del canal espinal luego de una cesárea. Nivel de Evidencia: IV


The presence of foreign elements within the spinal canal is rare and there is no clear consensus regarding its treatment. The publications on intracanal firearm projectile fragments recommend exeresis of the fragments due to the possibility of migration, especially when they are in an area close to the medullary cone. The same procedure should be applied to a needle inside the spinal canal. We present a patient with disabling radicular pain caused by a needle fragment within the spinal canal after cesarean section. Level of Evidence: IV

ABSTRACT

Microneedles have been developed rapidly in the field of transdermal administration in the past few decades. In recent years, the development of microelectronics technology has expanded the applications of microneedles by combining with microelectronic systems, especially in biological diagnosis and treatment. Different types of microneedles have been designed to extract blood and tissue fluids for detection, or as electrodes to directly detect blood sugar, melanoma and pH in real-time in vivo, both show good prospects for real-time detection applications. In this paper, we review the design of materials and structure of microelectronic-based microneedles, and discuss their advances in biological diagnosis.
