A new tuning fork with different vibration frequencies as an aid to bronchopulmonary hygiene physiotherapy

Background: The main function of the mucociliary system is the removal of particles or substances that are potentially harmful to the respiratory tract. The tuning fork therapeutic for the purpose of bronchial hygiene has still not been described in the literature. The optimal vibration frequency to mobilize secretions is widely debated and varies between 3 and 25 Hz. It is expected that a tuning fork is able to generate vibrations in the thorax, facilitating bronchial hygiene. The aim of the present study is to develop tuning forks with different frequencies, for use in bronchopulmonary hygiene therapy. Methods: The first tuning fork was made with a fixed frequency of 25 Hz and it was recorded in the Brazilian institution of patent registration. This device generated a frequency of 25 Hz and had a weight of 521 g, with dimensions of 600 mm in total length. The device is characterized by a bottom end containing a transducer with a diameter of 62 mm and a thickness of 5/16 mm (8''), a rod removable 148 mm, fork length of 362 mm and an extension at the upper end of sinuous shape bilaterally.The tuning forks must be applied at an angle of 90° directly on the chest wall of the patient after pulmonary auscultation for location of secretions. The tuning fork is activated by squeezing the tips of the extensions together and releasing them in a sudden movement. Results: This study shows the result of the development of others three tuning forks of different dimensions to generate different frequencies. Each equipment reaches a fixed frequency preset of 12, 15 and 20 Hz measured by digital oscilloscope. Conclusions: The tuning fork models developed in this study generated different frequencies proposed by the scientific literature as effective in the mobilization of pulmonary secretions.

Investigation of chemical changes in sealers during application of the warm vertical compaction technique

Aim To assess (i) heat generated by pluggers during warm vertical compaction of gutta-percha and investigation of temperature changes on the external root surface during canal filling, and (ii) the chemical changes of root canal sealers induced by heat.Methodology Four sealers, namely AH Plus, MTA Plus and two other experimental sealers based on tricalcium silicate, were characterised. External temperatures generated on the root surface during warm vertical compaction of gutta-percha with different sealers inside the root canal were monitored using an infrared thermography camera. Chemical changes induced by heating the sealers were assessed by Fourier transform infrared (FT-IR) spectroscopy.Results MTA Plus and the experimental sealers were composed of a cement and radiopacifier, with epoxy resin or a water-soluble polymer as dispersant, whilst AH Plus was epoxy resin-based. The heat generated at the tips of the continuous wave pluggers was found to be lower than the temperature set and indicated on the device LCD display. The sealers reduced the heat generated on the external root surfaces during the heating phase. AH Plus sustained changes to its chemical structure after exposure to heat, whilst the other sealers were unaffected.Conclusions The temperatures recorded at the tips of continuous wave pluggers varied with their taper and were lower than the temperature set on the System B LCD display. Root canal sealers reduced the dissipation of heat generated during warm vertical compaction, with the temperature at the external root surface maintained at 37-41 degrees C, a temperature below that is necessary to cause irreversible damage to bone and periodontium. The use of AH Plus sealer during warm vertical compaction techniques results in chemical changes in the sealer. The effect on sealer properties needs to be further investigated.

O uso da chupeta: elaboração de material pedagógico para orientação dos profissionais das escolas de educação infantil

What is the relationship of a pacifier as for nutrition, speech, dental and psychotherapy? What are its benefits and harm? Which strategies should be developed as a teaching material which can guide employees and teachers of early childhood education regarding the use of pacifier in schools? The survey is a qualitative and an exploratory one. By taking literature as a starting point. We found out that there are many doubts regarding the use of pacifier, even among health professionals. The booklet was prepared containing topics such as: social and historical aspects; psycho-physiological aspects of development, speech therapy and dental aspects; pros and cons of using a pacifier; teaching materials on the pedagogical use of pacifiers. Tips and information to the teacher

Comparação das técnicas semi-quantitativa e quantitativa nas infecções relacionadas a cateter em neonatos e determinação da resistência à oxacilina nos Staphylococcus spp

Study the semi-quantitative and quantitative technique in the diagnosis of catheter-related infections in newborns and to determine oxacillin resistance in Staphylococcus isolated. It was analyzed 353 catheter tips from 273 newborns in the Neonatal Unit of Hospital FMB. To confirm the diagnosis of infection, were analyzed the clinical data of newborns, the presence of at least one positive blood culture and growth of ≥ 1000 CFU/mL on quantitative culture and/or ³15 UFC on semiquantitative culture, with the same microorganism isolation (species and drug sensitivity) in blood culture and no other focus of infection except the catheter. The disk diffusion technique was used to check similarity of strains and resistance to oxacillin. Of the 353 tips analyzed, 39 were included in this study as the inclusion criteria. The semiquantitative culture was positive in 26 (66.7%) catheters and quantitative culture was positive in 24 (61.5%). Of 273 patients, 19 (6.9%) had a diagnosis of catheter-related bloodstream Infection (CR-BSI). Of the 19 episodes of CR-BSI, S. epidermidis was the predominant etiological agent (84.2%). The resistance to the antibiotic methicillin was found in 14 (73.7%) strains of Staphylococcus. The semiquantitative method was more sensitive (79%) compared with the quantitative method (63%). The use of antibiotics may have influenced the sensitivity of the quantitative method as the microorganisms present in the lumen are exposed to higher concentrations of antibiotics administered via the catheter

Square stepping exercise: uma revisão

Many studies inform that with aging process there’s a drop, not only in the cognitive functions, but also in the functional fitness. This drop can damage the old people’s daily activities, making them lose their independence. These declines can be softened with the practice of physical exercises. So, the aim of this study is to develop a systematic review in the literature which is the quantity of lectures done using the Square Stepping Exercise, we use a follow keyword “Square Stepping Exercise”. We performed a search in the following databases: PUBMED, Portal de Periódicos CAPES, Google Acadêmico e Catálogo Athena (acervo da Biblioteca de todos os campus da UNESP). Those procedures were complemented for manual searches in the references of the found lectures, like the access to the curriculum vitae, plataforma Lattes. There were analyzed articles, in Portuguese and English. Language were selected 11 studies (2 monografies, 1 masters lecture, 1 experience relatorie, 1 book chapter and 6 articles). The references found had improvement in motor and cognitive aspects. With this review, it was concluded that the SSE showed itself as a useful method to get better and/or maintain the analyzed aspects. It’s also necessary new studies with different populations, tips of analyse, periods of time and other aspects
