In vitro comparison of the efficacy of two fractured implant-prosthesis screw extraction methods: Conventional versus mechanical
ConclusionsMechanical extraction is more effective for extracting fractured implant-prosthetic screws, showing a higher probability of extraction than the conventional method. Prosthetic fixing screws with a smooth shaft and threaded apical area are the easiest to extract.
Conclusion: Antenatal detection of corpus callosum hypoplasia remains challenging. Counseling is difficult because neurodevelopmental outcomes are variable. PMID: 32070177 [PubMed - as supplied by publisher]

In this paper, a series of bismuth oxychloride were synthesized by ultrasonic-hydrothermal method with different ultrasonic time. By simply changing the ultrasonic time, we can control the morphology, structure, stoichiometry and photoelectric performance of bismuth oxychloride. The possible mechanism for the ...

Oleaginous yeasts have taken special attention due to the similarity of their metabolism with that of higher plants, and the numerous genetic tools available for their modification. However, a special need has been reported for efficient cell disruption technology due t...
ConclusionIn Europe in recent years for the availability of the vascular device of small dimensions and materials increasingly compatible, the "PICC-PORT" is positioned in the veins of the arm with ultrasound-guidance without complications such as pneumothorax, arterial puncture, hematoma of the neck, Pinch-off syndrome, such as the clinical case presented with extensive scars on the chest and neck. Thoracic devices (chest port, tunnel venous catheter) are not indicated in thickened and inelastic skins, due to the high risk of dehiscence of the surgical wound.
Preoperative ultrasound vessel mapping is a crucial step in operative planning for permanent hemodialysis access creation. Whereas the majority of the focus remains on vein caliber, anatomic arterial variants are often overlooked. Despite being a relatively common variation, little is known about the impact of a high brachial bifurcation on hemodialysis access outcomes. Our goal was to examine the relationship between a high brachial bifurcation and arteriovenous fistula (AVF) maturation and patency in patients undergoing upper arm hemodialysis access placement.
