Current advances and novel research on minimal invasive techniques for musculoskeletal disorders.
2021
Abstract The present review summarized the current advances and novel research on minimal invasive techniques for musculoskeletal disorders. Different invasive approaches were proposed in the physical therapy field for the management of musculoskeletal disorders, such as ultrasound-guided percutaneous needle electrolysis, dry needling, acupuncture and other invasive therapy techniques, discussing about their worldwide status, safety and interventional ultrasound imaging. Indeed, dry needling may be one of the most useful and studies invasive physical therapy applications in musculoskeletal disorders of different body regions, such as back, upper limb, shoulder, arm, hand, pelvis, lower limb…
Suture needles in Oral Surgery: Alterations depending on the type and number of sutures
2011
This study examined whether the number and type of sutures used in oral surgery influence two ad hoc variables (incision plane and displaced area), which are two variables related to whether the suture needle is suitable for the task. Seventy-five TB-15 needles were studied, which were used to suture between zero and three mucosa and/subperiosteal sutures, producing 15 groups with 5 needles in each one. The incision plane and displaced area were measured for each group, which are two variables related to how the needle has worn and altered. Statistical treatment was conducted using the Kruskal-Wallis H test to compare multiple values and the Mann-Whitney U test to compare pairs. A multi-sta…
OneShot-M: A New Device for Close Laparoscopy Pneumoperitoneum
2018
Introduction. The induction of pneumoperitoneum is the first and most critical phase of laparoscopy, due to the significant risk of serious vascular and visceral complications. The closed technique for the creation of pneumoperitoneum could lead to several surgical complications. The present study aimed to overcome the complications associated with the insertion of Veress needle, improving its use, and facilitating the rapid creation of pneumoperitoneum. Methods. Thirty large white female pigs were enrolled in our study. A common plunger was modified in order to allow the passage of a 15-cm long Veress needle. This method was applied to 26 laparoscopic procedures (26 pigs) of several speci…
The effect of the calibre and length of needle on the stability of sclerosing foam.
2020
Objectives Little is known how calibre and length of needles affect the stability of sclerosing foam. Methods Foams were made of 0.5%, 1%, 2% and 3% polidocanol, and 0.2%, 0.5%, 1% and 3% sodium tetradecyl sulfate (STS), which were mixed with air in the proportion of 4:1. These foams were ejected through needles with the length of: 4 mm, 6 mm and 13 mm, and diameter of: 0.26 mm, 0.3 mm and 0.4 mm. Results Foams made of more concentrated polidocanol were more stable. Regarding STS an opposite relationship was revealed. Foams made of polidocanol were more stable if ejected through a longer needle, while the length of needle did not significantly affect stability of STS foams. Foams ejected th…
Volatile oil content of Scots Pine needles (Pinus sylvestris L.)
2016
Badania dotyczą zmienności zawartości olejku eterycznego w igliwiu sosny zwyczajnej w zależności od wieku drzew, garnituru igieł oraz jego usytuowania w koronie. Materiał do badań stanowiło igliwie zebrane z drzewostanów sosnowych w wieku 15, 44 i 89 lat. W przeprowadzonych badaniach średnia zawartość olejków wzrastała wraz z wiekiem drzew. W igliwiu pochodzącym z 15-letniego młodnika zawartość olejku wynosiła średnio 0,46%, a w igliwiu drzewostanów 44- i 89-letnich odpowiednio 0,55 i 0,61%. Średnia zawartość olejku maleje wraz z wiekiem igliwia. Najwięcej olejku zawiera igliwie jednoroczne - 0,56%, najmniej igliwie trzyletnie - 0.48%. W drzewostanie 15-letnim stwierdzono wyraźny wzrost wyd…
Microneedle-Based Delivery: An Overview of Current Applications and Trends
2020
Microneedle arrays (MNA) are considered as one of the most promising resources to achieve systemic effects by transdermal delivery of drugs. They are designed as a minimally invasive, painless system which can bypass the stratum corneum, overcoming the potential drawbacks of subcutaneous injections and other transdermal delivery systems such as chemical enhancers, nano and microparticles, or physical treatments. As a trendy field in pharmaceutical and biomedical research, its applications are constantly evolving, even though they are based on very well-established techniques. The number of molecules administered by MNA are also increasing, with insulin and vaccines administration being the …
