Effects of condensates from volcanic fumaroles and cigarette smoke extracts on airway epithelial cells.

The impact of volcanic airborne products on airway epithelium homeostasis is largely unknown. This study assessed the effects of volcanic Fumarole Condensates (FC) alone or combined with Cigarette Smoke Extracts (CSE) on airway epithelial cells (16HBE and A549). Chemical composition of FC was analyzed by gas chromatography and HPLC.

A case of personalized and precision medicine: Pharmacometabolomic applications to rare cancer, microbiological investigation, and therapy.

Rationale: Advances in metabolomics, together with consolidated genetic approaches, have opened the way for investigating the health of patients using a large number of molecules simultaneously, thus providing firm scientific evidence for personalized medicine and consequent interventions. Metabolomics is an ideal approach for investigating specific biochemical alterations occurring in rare clinical situations, such as those caused by rare associations between comorbidities and immunosuppression.

Methods: Metabolomic database matching enables clear identification of molecular factors associated with a metabolic disorder and can provide a rationale for elaborating personalized therapeutic protocols.

Experimental study on strength evaluation applied for teeth extraction: an in vivo study.

Purpose: The aim of this work was to analyse all the applied movements when extracting healthy upper and lower jaw premolars for orthodontic purposes. The authors wanted to demonstrate that the different bone densities of the mandible and maxilla are not a significant parameter when related to the extraction force applied. The buccal and palatal rocking movements, plus the twisting movements were also measured in this in-vivo study during premolar extraction for orthodontic purposes.

Strategies used to inhibit postoperative swelling following removal of impacted lower third molar.

Postoperative swelling following different surgical strategies is an area of great interest. The main part of literature on the topic deals with swelling after extraction of low impacted third molar. In this review, we have analyzed publications of the last 20 years with a pubmed search using the following key words: impacted third molar, swelling third molar, wisdom tooth, edema jaw, corticosteroids and extraction third molar, antibiotic prophylaxis and tooth extraction.

The piezoelectric and rotatory osteotomy technique in impacted third molar surgery: comparison of postoperative recovery.

Purpose: The aim of this study was the comparison of postoperative outcome in mandibular impacted third molars treated by piezoelectric surgery or by rotatory osteotomy technique.

Patients And Methods: One hundred patients with impacted mandibular third molars were included in the study. Fifty patients were treated by rotatory osteotomy technique (group A) and 50 patients were treated by piezoelectric osteotomy technique (group B).

Silk and polyglycolic acid in oral surgery: a comparative study.

The inflammatory reaction caused by 2 different suture materials, black silk and polyglycolic acid, was evaluated 8 days after application and permanence in the oral environment. A randomized sample of 55 patients, aged 9 to 76, who had undergone oral urgery was examined. The suture materials (30 black silk and 25 polyglycolic acid), soon after removal, were placed in sterile containers and transferred to the laboratory.
