Benign paroxysmal positional vertigo (BPPV): it may occur after dental implantology. A mini topical review.

OBJECTIVE: Benign Paroxysmal Positional Vertigo (BPPV) is one of the most frequent vestibular disorders. BPPV as a complication of Osteotome Sinus Floor Elevation (OSFE) is a complication that rarely occurs. The aim of this paper is to better understand the mechanisms underlying the BPPV after SFE with the osteotomes. This could be important for all the dental and maxillofacial surgeons that should know and manage this clinical occurrence. DISCUSSION: The osteotome sinus floor elevation (OSFE), firstly described by Summers requires the use of a surgical mallet for striking the bone, until the optimal depth is reached. The surgical mallet develops a mechanical trauma, even if the striking is performed with a gentle percussion. The recent literature describes an average occurrence of OSFE-induced BPPV quite low, but the symptoms show to be unpleasant and severe, often able to alter the patient's daily life. CONCLUSIONS: A successful remission of BPPV following treatment with a particle repositioning maneuver will be necessary and relatively urgent for the surgeons who have experienced this clinical complication. The surgeons, therefore, must be aware of these complications and about the ways to manage them.

Comparison between PRP, PRGF and PRF: lights and shadows in three similar but different protocols.

OBJECTIVE: The main goal of the modern surgery is to get a low invasiveness and a high rate of clinical healing: in the last years, it has been introduced the concept of a "regenerative surgery", and many techniques has been widely described in the literature. The most used are PRP, PRGF and PRF techniques. Aim of this research is to compare the three protocol of PRP, PRF and PRGF in their essential features, so to suggest to the practitioners the best blood product to use in the regenerative surgery. DISCUSSION AND CONCLUSIONS: Among the advantages that shows the PRF, compared to PRP and PRGF, we can cite a greater simplicity of production for the absence of manipulation that leads to a reduced possibility of alteration of the protocol due to an error of the operator. The special texture of the PRF and its biological features shows clearly an interesting surgical versatility and all the characteristics that can support a faster tissues regeneration and high-quality clinical outcomes.

Primary aldosteronism with concurrent primary hyperparathyroidism: clinical case load in a single centre.

OBJECTIVE: Primary aldosteronism (PA) represents the main cause of endocrine secondary arterial hypertension in which aldosterone production is inappropriately elevated. Primary hyperparathyroidism (PHPT) is an endocrine disease characterized by hypercalcemia due to overproduction of parathyroid hormone (PTH). Although these two endocrine pathologies are secondary to hypertension in middle aged population, the occurrence of the PHPT in PA patients has rarely reported in the literature. The aim of the study was to describe some PA patients with concurrent PHPT, referred in a tertiary center of arterial hypertension. PATIENTS: We performed a retrospective study. In particular, the registry of 306 patients with PA seen in our center since 2004 was examined and revealed 8 patients (2.6%) with concurrent PHPT. CONCLUSIONS: There are several possible explanations for the association of these two endocrine disorders, including the combination was a random finding that PA inheres PHPT or vice versa.
