Tooth loss and radiographic bone loss in patients without regular supportive care: A retrospective study.

Background: Very few studies have investigated the effect of patient and site factors on periodontal progression and long-term tooth loss in populations with minimal dental care. The aim of this retrospective study was to assess tooth loss and radiographic bone loss over at least 5 years in patients attending a national-health service primary care practice in Sicily and undergoing no regular care.

Methods: Records of two hundred consecutive patients with at least 5 years follow-up were screened and demographic, clinical and radiographic data were retrieved.

Minimally Invasive Surgical Strategies in Regenerative/Reconstructive Periodontal Therapy.

Focused Clinical Question: After a quick overview on the original principles of guided periodontal regeneration (GTR), the aim of this paper focuses on the advantages of minimally invasive surgical techniques for periodontal regeneration/reconstruction. The specific clinical question to answer is: Are there new clinical parameters useful to choose the best minimal invasive surgery approach for each periodontal defect? An update of the decision trees is to propose after highlighting some clinical parameters deemed relevant for the choice of the most suitable minimally invasive surgical approach and which therefore are considered by us having a place in the new decision trees.

Summary: Starting from the paper of Evian dated 1985 until that of Aslan in 2017, we have analyzed the minimal periodontal surgical techniques proposed for the periodontal regeneration.

Vitamin E and selenium in broiler breeder diets: Effect on live performance, hatching process, and chick quality.

This study evaluated the effect of different dietary vitamin E levels and different selenium sources on the productive and reproductive performance of broiler breeders. In total 640 females and 64 males between 22 and 52 weeks old were studied. A completely randomized experimental design in factorial arrangement, with 4 treatments of 8 replicates with 20 females and 2 males each, was applied.

Primary carcinoma of the hypopharynx and cervical esophagus: evolution of surgical therapy.

Carcinoma of the cervical esophagus is invariably fatal because of its advanced stage at presentation. In our surgical division, 167 patients with primary squamous-cell carcinoma of the cervical esophagus were treated over the period between 1973 and June 1992. The tumor was localized in the cervical esophagus in only 37 cases, whereas it also involved the hypopharynx in 112 patients or extended to the cervico-thoracic segment in the remaining 18 subjects.

Induction therapy for squamous carcinoma of thoracic esophagus.

From June 1987 to March 1992, 70 patients with squamous cell carcinoma of the esophagus were entered into a treatment protocol that included a preoperative course of radiotherapy (3,000 cGy) and chemotherapy (cisplatin and 5-fluorouracil). The preoperative therapy was well tolerated. Forty-nine of these patients underwent esophageal resection (total or subtotal) and 6 patients died subsequently (12.
