This maneuver represents a simple and effective approach to the treatment of the apogeotropic variant of horizontal canal benign paroxysmal positional vertigo. It favors the shifting of the canaliths from the anterior into the posterior arm of the horizontal canal from where they can migrate into the utricle with Gufoni's maneuver.

This approach represents a simple and effective approach to the management of the geotropic form of HC-PPV.

An update of the geographical distribution of the sabellariid polychaete Sabellaria alveolata (Linnaeus, 1767) within the Mediterranean Sea is provided after checking the known literature. This shallow-water, reef-forming species is first recorded from new sites in southeastern Sicily, both along the Sicily Straits and the Ionian Sea, from where S. alveolata was so far unknown.These new collections also provided material for a detailed description and SEM documentation of morphological features of the operculum and the body.

In order to achieve perfusion of both lobes of the liver for hepatic arterial infusion chemotherapy, several surgical techniques can be used when the right hepatic artery arises from the superior mesenteric artery. Three of these techniques (utilization of cystic artery, end-to-side anastomosis between the right hepatic artery and proper hepatic artery, and insertion of a fine-tipped special catheter in the right hepatic artery) often require microsurgery applications.
