BackgroundThere is convincing evidence that dancers suffer injuries to the triceps surae musculature. Research on the immediate effects of dry needling (DN) is limited, and it is important to understand the acute effects of this treatment prior to performance.PurposeThe purpose of this pilot study was to assess the immediate effects of DN on myofascial trigger points in terms of skin surface temperature, pain, active and passive range of motion, and torque production in the triceps surae of ballet dancers.Study DesignRandomized, double-blinded pilot studyMethodsProfessional ballet dancers that fit inclusion and exclusion criteria (n=11) were randomly assigned to an experimental or control group. The dancers had three pre-determined standard point (SP) measurement spots that were used as a baseline for surface temperature comparisons. The dancers were also palpated for trigger point (TP) spots. Both SP and TP spots were marked for future measurements. The experimental group received DN, while the control group received sham DN (SHAM) to their bilateral calves at the TP spots. Immediately prior to and following treatment, both DN and SHAM groups were tested for skin surface temperature, pain, range of motion, and plantar flexion torque by blinded assessors. Paired t-tests and independent t-tests were performed to examine for differences between groups.ResultsThe surface temperature for the TP was higher than the SP measurements prior to intervention (Right calf p= .014; Left calf p= .031). There were no significant changes in VAS scale reported pain and ROM. The plantar flexion torque measurements showed an increase in the DN group of the left calf at the angular velocity of 60 degrees/sec.ConclusionThis was a unique pilot study examining the acute effects of DN on professional ballet dancers. The results were limited due to low sample size. However, the methodology for this study and surface temperature results invites future research.Level of evidenceLevel 1b 相似文献

PurposeA multidisciplinary team at our institution developed a novel method of intraoperative breast radiation therapy (precision breast intraoperative radiation therapy [PB-IORT]) that uses high-dose-rate brachytherapy with CT on-rails imaging to deliver high-dose, customized radiotherapy to patients with early-stage breast cancer. This report summarizes our program's experience developing and implementing PB-IORT.Methods and MaterialsLiterature on PB-IORT was reviewed including published articles and abstracts. To evaluate case volume, all patients with a breast cancer diagnosis who underwent breast surgery or breast radiation (2010–2017) at our academic institution were identified. Patients were stratified into pre-IORT and post-IORT eras with initiation of our PB-IORT program in October 2013. Overall trends in surgical and radiation therapy volume in each era were analyzed by linear regression. Travel distance for all surgical patients was calculated using Google Maps (Alphabet Inc.) and then compared between IORT and non-IORT patients.ResultsData from a PB-IORT Phase 1 trial found that the primary endpoints were met and that PB-IORT is feasible and safe. The direct health system's delivery costs for PB-IORT exceed those of 16-fraction whole-breast irradiation when accounting for consumable supplies (multilumen balloon applicator = $2,750 per patient). There was a significant increase in yearly growth of breast cancer surgical volume with PB-IORT.ConclusionsAccrual rates for the ongoing Phase II trial have been quicker than expected in an area where more research is needed. The rapid accrual indicates patient interest and demand for this treatment and that it is very feasible to get more data from randomized trials. 相似文献

The purpose of this study was to analyse the associations of emotional control with sociodemographic and clinical variables in a sample of patients with a range of chronic somatic diseases. The relationships between emotional control, coping styles and adjustment to the disease were investigated. The sample consisted of 300 patients with the mean age of 54.60 ± 17.57 years. Courtauld Emotional Control Scale was used to measure the patients' tendency to suppress negative emotions, Coping Inventory for Stressful Situations was used to measure coping styles and Acceptance of Illness Scale was applied to determine adjustment to the disease. Patients with neurological conditions showed significantly lower suppression of anger. Levels of emotional control were found to be related to gender, age and educational level but not to the place of residence. Task‐oriented style of coping with stress correlated positively with suppression of depression and anxiety, whereas acceptance of illness correlated negatively with suppression of anger. Levels of emotional control are only weakly related to the type of diagnosis; however, some clinical samples may show lower suppression of anger. Suppression of negative emotions is weakly related to adjustment indicators such as certain coping styles and acceptance of illness. Copyright © 2013 John Wiley & Sons, Ltd. 相似文献

In the paper we presented results of clinical and epidemiological analysis of 32 patients with botulism hospitalized at the Department of Infectious Diseases, Medical University of Lublin in 1990-2000. In the studied group, the relationships between botulism incidence and sex and place of residence were not significant. The incubation period ranged from 7 hours to 5 days (average 36 hrs). The clinical manifestations of botulism were typical in all cases. In one female patient the course of disease was complicated. She developed right-sided bronchopneumonia and left-sided purulent parotitis. The type B botulinum toxin occurred more frequently than the other types and the cases without serological confirmation (Chi 2 = 6.125 p = 0.01). It was found in serum of 23 patients (in 2 cases together with the type A toxin). The type E toxin was found in serum of one patient. The presence of toxin in serum was not detected in 8 patients. In all patients trivalent (types A, B and E) equine antitoxin was administered. The dose ranged from 50 to 150 cm3. Symptomatic treatment was given in all cases. Nobody required mechanical ventilation. The duration of hospitalization ranged from 5 to 28 days (average 16.6 days). A few patients complained of long-lasting blurred vision or dry mouth. 相似文献

Ecthyma gangrenosum is a cutaneous gangrenous disorder which usually follows Pseudomona aeruginosa infection and is found mainly in immunosuppressed children. We describe a case of a five-year-old female with leukemia with a severe perineal ecthyma gangrenosum resulting in a cloaca-like deformity. One year later a perineoplasty with puborectalis interposition and overlapping external anal sphincteroplasty was successfully performed, achieving satisfactory continence. 相似文献

Many types of neural progenitors from various sources have been evaluated for therapy of CNS disorders. Prerequisite for success in cell therapy is the ability for transplanted cells to reach appropriate target such as stroke lesion. We have established neural stem cell line from human umbilical cord blood neural stem (HUCB-NSC). In the present study we evaluated migratory capabilities of cells (HUCB-NSC) and the presence of various migration-related receptors. Immunocytochemical analysis revealed abundant expression of CXCR4, PDGFR-alpha, PDGFR-beta, c-Met, VEGFR, IGF-1R and PSA-NCAM receptors in non-adherent population of HUCB-NSC cultured in serum free (SF) conditions (SF cells). Biological activity of selected receptors was confirmed by HUCB-NSC in vitro migration towards SDF-1 and IGF-1 ligands. Additionally, rat brain-derived homogenates have been assessed for their chemoattractive activity of HUCB-NSC. Our experiments unveiled that brain tissue was more attracted for HUCB-NSC than single ligands with higher potency of injured than intact brain. Moreover, adherent HUCB-NSC cultured in low serum (LS) conditions (LS cells) were employed to investigate an impact of different extracellular matrix (ECM) proteins on cell motility. It turned out that laminin provided most permissive microenvironment for cell migration, followed by fibronectin and gelatin. Unexpected nuclear localization of CXCR4 in SF cells prompted us to characterize intracellular pattern of this expression in relation to developmental stage of cells cultured in different conditions. Continuous culture of LS cells revealed cytoplasmatic pattern of CXCR4 expression while HUCB-NSC cultured in high serum conditions (HS cells) resulted in gradual translocation of CXCR4 from nucleus to cytoplasm and then to arising processes. Terminal differentiation of HUCB-NSC was followed by CXCR4 expression decline. 相似文献

Pneumonia and influenza (P & I) constitute Florida's sixth leading cause of death. The P & I death rate in 1987, 10.5 per 100,000, was the highest since 1978. Major target groups for one or both vaccines used in prevention, as recommended by the Immunization Practices Advisory Committee (ACIP), include persons with chronic diseases of the heart or lungs, residents of nursing homes and other chronic care facilities, and persons aged 65 and older. Despite well-defined recommendations, vaccine coverage rates in Florida are as low as 30% in persons greater than or equal to 65 years of age. Knowledge and attitude surveys demonstrate that low coverage among various population groups may be due largely to insufficient awareness and/or negative attitudes regarding pneumococcal and influenza vaccines. Conversely, recommendations by physicians and other health care providers are strongly associated with receiving either vaccine. If the incidence of P & I is to decrease substantively in Florida, much wider use of the vaccines must occur. Because so many high-risk patients depend on private physicians for health care, their role is critical to the success of Florida public health strategies to reverse P & I trends. 相似文献

Pulmonary uptake of basic amine xenobiotics such as lidocaine may influence the onset of drug effect and ameliorate toxicity. To date, pharmacokinetic analysis of pulmonary drug uptake has been only semiquantitative and ill-suited for relating pharmacodynamics to pharmacokinetics or jar estimating the time course of the fraction of drug dose residing in the lung during a single pass. We have developed recirculatory models in an experiment in which lidocaine was injected into the right atrium simultaneously with markers of intravascular space (indocyanine green) and total body water (antipyrine): this was followed by rapid arterial and mixed venous blood sampling. Such models are interpretable physiologically and are capable of characterizing the kinetics of the pulmonary uptake of lidocaine in addition to peripheral tissue distribution and elimination. The apparent pulmonary tissue volume of lidocaine (39 ml/kg) was nearly ninefold greater than that of antipyrine (4.5 ml/kg). The recirculatory model characterized both arterial and mixed venous data, but the latter data were not essential for estimating lidocaine's pulmonary disposition either before or after recirculation of drug was evident. 相似文献
