Eficácia da auriculoterapia para diminuição de estresse em estudantes de enfermagem: ensaio clínico randomizado

Trata-se de estudo clínico randomizado, simples cego, com o objetivo de avaliar a eficácia da auriculoterapia verdadeira e placebo na diminuição dos níveis de estresse em alunos de nível médio, da Escola de Enfermagem do Hospital Beneficência Portuguesa. Setenta e um estudantes com escores médio, alto e altíssimo, pela Lista de Sintomas de Estresse de Vasconcellos, foram divididos em 3 grupos: controle (25), auriculoterapia (24) e placebo/Sham (22). Foram avaliados, no início, com 8, 12 sessões e follow-up (15 dias) e receberam os pontos Shen Men, tronco cerebral (auriculoterapia) e punho e ouvido externo (placebo/Sham). Na análise de variância (Anova) constataram-se diferenças estatísticas significativas entre os grupos controle/auriculoterapia a partir de 8 sessões, mantendo-se após a terceira e a quarta avaliação (p=0,000) e entre controle/placebo (p<0,05), nas três avaliações. Concluiu-se que a auriculoterapia verdadeira obteve melhores respostas (45,39%) do que o placebo (34,18%) na redução do estresse, mas recomendam-se mais estudos para reavaliação de pontos Sham para estresse.

Aplicabilidade da auriculoterapia para reduzir estresse e como estratégia de coping em profissionais de enfermagem

OBJETIVOS: trata-se de ensaio clínico randomizado com o objetivo de avaliar a auriculoterapia, para diminuição de níveis de estresse, em 75 profissionais de enfermagem de um hospital e analisar os principais domínios de coping que se modificaram após o tratamento. METODOLOGIA: os sujeitos foram divididos em grupos (controle, agulhas, sementes), receberam 8 sessões nos pontos Shenmen, rim e tronco cerebral. O grupo controle não recebeu nenhuma intervenção. RESULTADOS: constataram-se diferenças significativas pela ANOVA, para níveis de estresse entre o grupo agulha/controle na terceira e quarta avaliações, segundo escores de estresse da Lista de Sintoma de Stress de Vasconcelos. Para o Inventário de Folkman e Lazarus, obteve-se diferença estatística para o domínio afastamento entre os grupos agulha/controle, após tratamento; e, na análise dentro do mesmo grupo, obtiveram-se diferenças significativas para o domínio confronto, na quarta avaliação entre grupos agulha/controle e para suporte social, na terceira avaliação para os grupos agulha/semente. CONCLUSÕES: a auriculoterapia com agulhas diminuiu os níveis de estresse significativamente e houve diminuição da utilização dos domínios afastamento, confronto e suporte social para os grupos de intervenção, após o tratamento, sugerindo que a auriculoterapia tanto com agulhas quanto com sementes pode produzir impacto positivo para melhorar a estratégia de coping na equipe de enfermagem. Mais estudos, porém, fazem-se necessários para que se possa conhecer o alcance da técnica.

The combined effect of acupuncture and Tanacetum parthenium on quality of life in women with headache: randomised study

Background The aim of the present study was to investigate the efficacy and tolerability of acupuncture (AC), Tanacetum (TAN) or combined treatment on quality of life in women with chronic migraine (CM). Methods A total of 69 women volunteers were randomly divided into 3 groups: AC, acupuncture administered in 20 sessions over 10 weeks (n=22); TAN, at 150 mg/day (n=23); and AC+TAN (n=23). The primary outcome was Short-Form 36 (SF-36) quality of life assessment score. Secondary outcomes included the Migraine Disability Assessment (MIDAS) and visual analogue scale (VAS) score experienced after randomisation. Results AC+TAN was statistically significantly more effective than AC or TAN alone in overall health-related quality of life (SF-36; p<0.05), on MIDAS score (-35.1 (10.6) AC vs -24.8 (11.7) TAN vs -42.5 (9.8) AC+TAN; p<0.05) and in reducing the mean score of pain on VAS (-5.6 (2.4) AC vs -3.7 (2.1) TAN vs -6.4 (3.1) AC+TAN; p<0.05). Conclusions The present work shows an improvement of the quality of life and better analgesic effect of acupuncture combined with TAN treatment on migraine pain in women when compared with acupuncture or TAN alone.

Clinical Effects of Scalp Electrical Acupuncture in Stroke: A Sham-Controlled Randomized Clinical Trial

Objectives: The majority of individuals who survive a stroke are disabled because of persisting neurological impairments. The objective of this study was to evaluate the efficacy of subcutaneous electrical stimulation of the scalp in spontaneous functional recovery of patients with chronic ischemic stroke, by evaluating clinical, neurological, and functional findings. Subjects and methods: Sixty-two (62) subjects who were at least 18 months postdiagnosis of ischemic stroke were randomized to receive 10 sessions of placebo or active low-frequency electrical stimulation (2/100 Hz) using subcutaneous acupuncture needles over the scalp. Functional and neurological evaluations were indexed by the Barthel, Rankin, and National Institutes of Health Stroke Scale (NIHSS). Results: Results show that there was a significant difference in functional improvement between the sham and active group as indexed by NIHSS scale. The active group had a larger functional improvement after 10 sessions of scalp electrical acupuncture. The other two functional scales (Rankin and Barthel) failed to show significant differences between the two treatment groups. Conclusions: These results support further testing of scalp electrical acupuncture for the treatment of stroke as well further mechanistic studies to understand mechanisms associated with the observed improvement. Further studies need to consider longer follow-up assessments to investigate potential functional changes associated with electrical acupuncture.

Amitriptyline prolongs the antihyperalgesic effect of 2- or 100-Hz electro-acupuncture in a rat model of post-incision pain

The mechanisms through which electro-acupuncture (EA) and tricyclic antidepressants produce analgesia seem to be complementary: EA inhibits the transmission of noxious messages by activating supraspinal serotonergic and noradrenergic neurons that project to the spinal cord, whereas tricyclic antidepressants affect pain transmission by inhibiting the reuptake of norepinephrine and serotonin at the spinal level. This study utilized the tail-flick test and a model of post-incision pain to compare the antihyperalgesic effects of EA at frequencies of 2 or 100 Hz in rats treated with intraperitoneal or intrathecal amitriptyline (a tricyclic antidepressant). A gradual increase in the tail-flick latency (TFL) occurred during a 20-min period of EA. A strong and long-lasting reduction in post-incision hyperalgesia was observed after stimulation; the effect after 2 Hz lasting longer than after 100-Hz EA. Intraperitoneal or intrathecal amitriptyline potentiated the increase in TFL in the early moments of 2- or 100-Hz EA, and the intensity of the antihyperalgesic effect of 100-Hz EA in both the incised and non-incised paw. In contrast, it did not significantly change the intensity of the antihyperalgesic effect of 2-Hz EA. The EA-induced antihyperalgesic effects lasted longer after intraperitoneal or intrathecal amitriptyline than after saline, with this effect of amitriptyline being more evident after 100-than after 2-Hz EA. The synergetic effect of amitriptyline and EA against post-incision pain shown here may therefore represent an alternative for prolonging the efficacy of EA in the management of post-surgical clinical pain.

SLEEP QUALITY OF OBESE WORKERS OF A TEACHING HOSPITAL: ACUPUNCTURE AS A COMPLEMENTARY THERAPY

The objective of this study was to verify the effect of acupuncture on the sleep quality of obese workers in a teaching hospital. Data were collected from July to October 2009, focusing on 37 workers who attended eight weekly acupuncture sessions. The Pittsburgh Sleep Quality Index was used to assess their sleep quality before and after the intervention. Results show that before the intervention, five (13.5%) people experienced good quality of sleep whereas at the end of the study 14 (37.8%) showed this condition. Statistic significance (p=0.0001) was found in comparing the mean scores obtained before and after acupuncture. Acupuncture had effects on the quality of sleep in the studied sample, presenting itself as a complementary technique for treating sleep disorders and consequently improving the quality of life in this population.

The immediate effects of local and adjacent acupuncture on the tibialis anterior muscle: a human study

Abstract Background This study compares the immediate effects of local and adjacent acupuncture on the tibialis anterior muscle and the amount of force generated or strength in Kilogram Force (KGF) evaluated by a surface electromyography. Methods The study consisted of a single blinded trial of 30 subjects assigned to two groups: local acupoint (ST36) and adjacent acupoint (SP9). Bipolar surface electrodes were placed on the tibialis anterior muscle, while a force transducer was attached to the foot of the subject and to the floor. An electromyograph (EMG) connected to a computer registered the KGF and root mean square (RMS) before and after acupuncture at maximum isometric contraction. The RMS values and surface electrodes were analyzed with Student's t-test. Results Thirty subjects were selected from a total of 56 volunteers according to specific inclusion and exclusion criteria and were assigned to one of the two groups for acupuncture. A significant decrease in the RMS values was observed in both ST36 (t = -3.80, P = 0,001) and SP9 (t = 6.24, P = 0.001) groups after acupuncture. There was a decrease in force in the ST36 group after acupuncture (t = -2.98, P = 0.006). The RMS values did not have a significant difference (t = 0.36, P = 0.71); however, there was a significant decrease in strength after acupuncture in the ST36 group compared to the SP9 group (t = 2.51, P = 0.01). No adverse events were found. Conclusion Acupuncture at the local acupoint ST36 or adjacent acupoints SP9 reduced the tibialis anterior electromyography muscle activity. However, acupuncture at SP9 did not decrease muscle strength while acupuncture at ST36 did.

Enxerto composto auricular na reconstrução da asa nasal

O nariz ocupa o centro da face, o que torna pequenas assimetrias e imperfeições evidentes. Uma de suas subunidades é a asa nasal, região que exige não apenas resultados estéticos, mas também funcionais, em sua reconstrução, tornando-se um desafio ao cirurgião plástico. Neste artigo são descritos 3 casos em que foi utilizado enxerto composto auricular para reconstrução da asa nasal. Os enxertos apresentaram integração total, com resultados estéticos e funcionais adequados. Segundo revisão da literatura, não há diferença nos índices de complicação comparando-se os enxertos com os retalhos locais e, a longo prazo, a cartilagem auricular tende a manter-se no formato moldado, sofrendo raras distorções e mínima ou nenhuma absorção, diferentemente das cartilagens costais e dos enxertos ósseos. O enxerto composto auricular é uma técnica versátil e segura, com excelentes resultados na reconstrução da asa nasal e com baixa morbidade das áreas doadoras, cumprindo com eficiência seu objetivo reparador.

THE APPLICABILITY OF AURICULOTHERAPY WITH NEEDLES OR SEEDS TO REDUCE STRESS IN NURSING PROFESSIONALS

This clinical randomized trial was performed with the objective to evaluate the stress levels of the nursing staff of a hospital and analyze the effectiveness of auriculotherapy with needles and seeds. The 75 participants with mean (44/58.7%) and high (31/41.3%) scores according to the Stress Symptoms List were divided into groups (control, needles, and seeds), who received eight sessions on the Shenmen, Kidney and Brainstem points and were evaluated at the baseline, fourth and eighth sessions and on the 15-day follow-up session. The analysis of variance (ANOVA) showed significant differences among the groups at the third assessment (F=3.963/P=0.023) and follow-up (F=6.136/P=0.003). These differences occurred between the control and needle groups. The 'seeds' and needles groups both showed differences (p < 0.05) at the second assessment when compared within the same group. In conclusion, auriculotherapy reduced the stress in the nursing staff, with needles showing better results than seeds for high scores, maintaining the effects for 15 days.

Extraoral Implants in the Rehabilitation of Craniofacial Defects: Implant and Prosthesis Survival Rates and Peri-Implant Soft Tissue Evaluation

Purpose: Few reports have evaluated cumulative survival rates of extraoral rehabilitation and peri-implant soft tissue reaction at long-term follow-up. The objective of this study was to evaluate implant and prosthesis survival rates and the soft tissue reactions around the extraoral implants used to support craniofacial prostheses. Materials and Methods: A retrospective study was performed of patients who received implants for craniofacial rehabilitation from 2003 to 2010. Two outcome variables were considered: implant and prosthetic success. The following predictor variables were recorded: gender, age, implant placement location, number and size of implants, irradiation status in the treated field, date of prosthesis delivery, soft tissue response, and date of last follow-up. A statistical model was used to estimate survival rates and associated confidence intervals. We randomly selected 1 implant per patient for analysis. Data were analyzed using the Kaplan-Meier method and log-rank test to compare survival curves. Results: A total of 150 titanium implants were placed in 56 patients. The 2-year overall implant survival rates were 94.1% for auricular implants, 90.9% for nasal implants, 100% for orbital implants, and 100% for complex midfacial implants (P = .585). The implant survival rates were 100% for implants placed in irradiated patients and 94.4% for those placed in nonirradiated patients (P = .324). The 2-year overall prosthesis survival rates were 100% for auricular implants, 90.0% for nasal implants, 92.3% for orbital implants, and 100% for complex midfacial implants (P = .363). The evaluation of the peri-implant soft tissue response showed that 15 patients (26.7%) had a grade 0 soft tissue reaction, 30 (53.5%) had grade 1, 6 (10.7%) had grade 2, and 5 (8.9%) had grade 3. Conclusions: From this study, it was concluded that craniofacial rehabilitation with extraoral implants is a safe, reliable, and predictable method to restore the patient's normal appearance.

Morphological and Biometric Study of the Infraorbital Foramen (E2-Sibai Point) in Adult Skulls

The objective of this work was to study the morphology and biometry of the infraorbital foramen (FIO), variations in its shape, size and number as well as to obtain measurements of its location. 60 dry skulls were analyzed. The test of Qui-quadrant and the T Test were used in measurements with a 5% significance. On the right side, the FIO was measured at a distance of 6.49(+/- 1.68) mm from the lower, 39.65(+/- 3) mm from the upper, 17.7(+/- 2.97) mm from the medial and 20.46(+/- 2.9) mm from the lateral margin of the orbit; its pear-shaped opening distance was 13.67(+/- 2.17) mm. On the left side, the distance of the FIO to the lower margin of the orbit was 6.52(+/- 1.82) mm; to the upper margin was 39.9(+/- 2.62) mm and to the lateral and medial margin were 17.93(+/- 2.58) mm and 21.12(+/- 3) mm, respectively; its distance to the pear-shaped opening was 14.26(+/- 1.83) mm. It was found predominately in an oval shape, in 39 (65%) of the skulls, on both sides. Accessory foramens were present in 11 samples on the right and in 15 samples on the left side. The FIO was most frequently found on the side of, or laterally to the sagittal plane that passes through the middle of the supraorbital foramen/incisures, in 38 skulls (63.3%) on the right side and in 45 skulls (75%) on the left and middle to the zigomatic-maxillary suture, in 41 skulls (68.3%) on right and in 42 skulls (70%) on the left side, besides being most frequently found in a region between the first and second premolars, in 22 skulls (36.7%) on the right side and in 17 skulls (28.3%) on the left.

AURICULOTHERAPY EFFECTIVENESS IN THE REDUCTION OF ANXIETY IN NURSING STUDENTS

The objective of this single-blinded randomized controlled trial was to assess anxiety levels in nursing school students of the Beneficencia Portuguesa Hospital (Sao Paulo) and the effectiveness of auriculotherapy in the reduction of these levels. The Trait-Anxiety Inventory State was applied at the beginning of the study, after 8 and 12 sessions, and at follow-up (15 days). The sample was comprised of 71 students divided into 3 groups: control without intervention (25), auriculotherapy (24), and placebo (22). The analysis of variance (ANOVA) showed statistically significant differences post hoc between the control and auriculotherapy groups at 2nd (p=0.000), 3rd (p=0.012) and 4th assessments (p=0.005), and between placebo and control groups at 2nd assessment (p=0.003). Auriculotherapy with Shenmen and Brain Stem points was more effective (20.97%) than sham points (13.74%) for reduction of anxiety levels in Nursing students, but studies with more representative samples are recommended.

Short-term efficacy of physical interventions in osteoarthritic knee pain. A systematic review and meta-analysis of randomised placebo-controlled trials

Abstract Background Treatment efficacy of physical agents in osteoarthritis of the knee (OAK) pain has been largely unknown, and this systematic review was aimed at assessing their short-term efficacies for pain relief. Methods Systematic review with meta-analysis of efficacy within 1–4 weeks and at follow up at 1–12 weeks after the end of treament. Results 36 randomised placebo-controlled trials (RCTs) were identified with 2434 patients where 1391 patients received active treatment. 33 trials satisfied three or more out of five methodological criteria (Jadad scale). The patient sample had a mean age of 65.1 years and mean baseline pain of 62.9 mm on a 100 mm visual analogue scale (VAS). Within 4 weeks of the commencement of treatment manual acupuncture, static magnets and ultrasound therapies did not offer statistically significant short-term pain relief over placebo. Pulsed electromagnetic fields offered a small reduction in pain of 6.9 mm [95% CI: 2.2 to 11.6] (n = 487). Transcutaneous electrical nerve stimulation (TENS, including interferential currents), electro-acupuncture (EA) and low level laser therapy (LLLT) offered clinically relevant pain relieving effects of 18.8 mm [95% CI: 9.6 to 28.1] (n = 414), 21.9 mm [95% CI: 17.3 to 26.5] (n = 73) and 17.7 mm [95% CI: 8.1 to 27.3] (n = 343) on VAS respectively versus placebo control. In a subgroup analysis of trials with assumed optimal doses, short-term efficacy increased to 22.2 mm [95% CI: 18.1 to 26.3] for TENS, and 24.2 mm [95% CI: 17.3 to 31.3] for LLLT on VAS. Follow-up data up to 12 weeks were sparse, but positive effects seemed to persist for at least 4 weeks after the course of LLLT, EA and TENS treatment was stopped. Conclusion TENS, EA and LLLT administered with optimal doses in an intensive 2–4 week treatment regimen, seem to offer clinically relevant short-term pain relief for OAK.

A systematic review with procedural assessments and meta-analysis of Low Level Laser Therapy in lateral elbow tendinopathy (tennis elbow)

Abstract Background Recent reviews have indicated that low level level laser therapy (LLLT) is ineffective in lateral elbow tendinopathy (LET) without assessing validity of treatment procedures and doses or the influence of prior steroid injections. Methods Systematic review with meta-analysis, with primary outcome measures of pain relief and/or global improvement and subgroup analyses of methodological quality, wavelengths and treatment procedures. Results 18 randomised placebo-controlled trials (RCTs) were identified with 13 RCTs (730 patients) meeting the criteria for meta-analysis. 12 RCTs satisfied half or more of the methodological criteria. Publication bias was detected by Egger's graphical test, which showed a negative direction of bias. Ten of the trials included patients with poor prognosis caused by failed steroid injections or other treatment failures, or long symptom duration or severe baseline pain. The weighted mean difference (WMD) for pain relief was 10.2 mm [95% CI: 3.0 to 17.5] and the RR for global improvement was 1.36 [1.16 to 1.60]. Trials which targeted acupuncture points reported negative results, as did trials with wavelengths 820, 830 and 1064 nm. In a subgroup of five trials with 904 nm lasers and one trial with 632 nm wavelength where the lateral elbow tendon insertions were directly irradiated, WMD for pain relief was 17.2 mm [95% CI: 8.5 to 25.9] and 14.0 mm [95% CI: 7.4 to 20.6] respectively, while RR for global pain improvement was only reported for 904 nm at 1.53 [95% CI: 1.28 to 1.83]. LLLT doses in this subgroup ranged between 0.5 and 7.2 Joules. Secondary outcome measures of painfree grip strength, pain pressure threshold, sick leave and follow-up data from 3 to 8 weeks after the end of treatment, showed consistently significant results in favour of the same LLLT subgroup (p < 0.02). No serious side-effects were reported. Conclusion LLLT administered with optimal doses of 904 nm and possibly 632 nm wavelengths directly to the lateral elbow tendon insertions, seem to offer short-term pain relief and less disability in LET, both alone and in conjunction with an exercise regimen. This finding contradicts the conclusions of previous reviews which failed to assess treatment procedures, wavelengths and optimal doses.

The antinociceptive effect of electroacupuncture at different depths of acupoints and under the needling surface

Background The stimulation of acupoints along the meridians, but not the non-acupoints outside of the meridians, produces analgesia. Although the acupoint is defined at the body surface, the exact location of the acupoints is not known. This study aims to examine whether the intensity and duration of the analgesic effect of electroacupuncture (EA) at the Zusanli (ST36) and Sanynjiao acupoints (SP6) change according to the depth of the stimulation. Methods Ninety-six male Wistar rats classified as responders were arbitrarily allocated into 16 groups of six rats each. Six groups received EA with uninsulated acupuncture needles (type I) or needles that were immersed in varnish and had the varnish circularly peeled 0.2 mm from the tip (type II), 0.2 mm at 3 mm (type III) or 5 mm (type IV) from the tip, or 0.2 mm at 5 and 1 mm from the tip (type V), or EA sham for 20 min. Five groups received injection of formalin into the acupoint bilaterally at 5 mm or 1 mm deep into ST36, 5 mm below ST36 but inserting the needle at 45° to the skin surface, or 5 mm deep into non-acupoints. The remaining groups received intraplantar injection of saline, 1% or 2.5% formalin. The analgesic effects were measured by the rat tail-flick test. Results The bilateral stimulation of ST36 and SP6 by uninsulated or insulated needles produced analgesia in the rat tail-flick test. The stronger and longer lasting effects occurred after EA with the types I and V needles, or injection of formalin 5 mm deep into ST36. The remaining needles produced weaker and shorter lasting effects. Slow analgesic effect also occurred after formalin injection at 1 mm or 5 mm below ST36 by inserting the needle at 45° to the skin surface. Conclusion The experimental results suggest that the efficacy of the EA stimulation depends on the spatial distribution of the current density under the needling surface rather than only the acupoint or the depth of needling.
