A retrospective analysis of autotransplanted teeth including an evaluation of a novel surgical technique.

Objectives: To assess survival rates and frequency of complications for immature and mature autotransplanted teeth after at least 1 year in function.

Materials And Methods: All consecutive patients who had undergone tooth autotransplantation between 2000 and 2018 were invited to a clinical and radiographic follow-up examination. First, survival rates were calculated on the basis of a phone inquiry.

Analysis of trends in implant therapy at a surgical specialty clinic: Patient pool, indications, surgical procedures, and rate of early failures-A 15-year retrospective analysis.

Objectives: To evaluate the patient population over a 3-year period and to compare it to observations of the population at the same clinic over a period of 15 years.

Material And Methods: Records of patients receiving dental implants in the Department of Oral Surgery and Stomatology, University of Bern, between January 2014 and December 2016 were analyzed and then compared with data from patients treated between 2002 and 2004 and between 2008 and 2010. Patients were analyzed for demographics and for indications for therapy, as well as for presence or absence and type of complications.

Distances of root apices to adjacent anatomical structures in the anterior maxilla: an analysis using cone beam computed tomography.

Objectives: The aim was to assess the anatomical relationship of anterior maxillary teeth to the nasal floor in patients referred for apical surgery.

Materials And Methods: Cone beam computed tomographic images (CBCT) of 83 patients were analysed retrospectively to quantify the distances between the root apices of maxillary anterior teeth (canine to canine) to the nasal floor or maxillary sinus (whichever was closer). Secondary outcome variables were the distances of the periapical lesion to the nasal floor, distances of the apices to the labial and palatal bone plates as well as to the neighbouring teeth.

[Osseous dysplasia: an incidental radiological finding].

Osseous dysplasias (OD; formerly known as cemento-osseous dysplasias) are idiopathic changes in the area of the tooth-bearing alveolar process. The normal bone structure is replaced by fibroblasts and collagen fibres and later by mineralized tissue and bone. In the current WHO classification, ODs are categorized as bone-associated lesions or non-neoplastic, fibro-osseous lesions of the head and neck region.

Assessment of the nonoperated root after apical surgery of the other root in mandibular molars: a 5-year follow-up study.

Introduction: If a surgical approach is chosen to treat a multirooted tooth affected by persistent periapical pathosis, usually only the affected roots are operated on. The present study assessed the periapical status of the nonoperated root 5 years after apical surgery of the other root in mandibular molars.

Methods: Patients treated with apical surgery of mandibular molars with a follow-up of 5 years were selected.

[Autoimmune hepatitis].

Autoimmune hepatitis is a systemic disease, difficult to diagnose due the high variability of the clinical presentation and some non specific histological features. The recent identification of additional autoantibodies used as serological markers, as well as simplified diagnostic criteria should help the primary care physician to advance with the diagnostic process. These progresses are crucial as undiagnosed and therefore untreated autoimmune hepatitis has a poor prognosis, whereas immunosuppressive therapy leads to remission in a majority of cases.

[House dust mite allergy: myths and realities].

Since 1967, house dust mites have been shown to be the main allergens to be blamed in household dust allergy. In our countries, Dermatophagoides pteronyssinus and Dermatophagoides farinae are predominant. We find them by millions in our bedding.

Introducing DNA concepts to Swiss high school students based on a Brazilian educational game.

Subjects such as techniques for genetic diagnosis, cloning, sequencing, and gene therapy are now part of our lives and raise important questions about ethics, future medical diagnosis, and such. Students from different countries observe this explosion of biotechnological applications regardless of their social, academic, or cultural backgrounds, although they are not usually familiar with their theoretical genetic bases. To introduce some molecular biology concepts for high school students, we developed a new problem for the Brazilian board game "Discovering the cell" ("Célula Adentro©" in Portuguese), a pedagogic tool based on inquiry-, cooperative-, and problem-based learning.

Outbreak of human listeriosis associated with tomme cheese in northwest Switzerland, 2005.

During an eight week period in spring 2005, 10 cases of listeriosis were reported in a small area of northwest Switzerland (150,000 inhabitants). Eight cases were in older immunocompromised patients who became ill with bacteraemia (three deaths), and two cases were in pregnant women who had septic abortion. All cases were due to a serotype 1/2a isolate with one of two pulsovars found by PFGE.

Thrombosed aneurysmal nonpatent ductus arteriosus: a case report.

We report our observations made clinically and by conventional radiography, ultrasound, computed tomography and MRI on a newborn full-term infant with a thrombosed patent aneurysmal ductus arteriosus of Botallo. The baby had no heart murmurs, but from the beginning of the 2nd day of life developed sinus tachycardia, especially when in a left-sided position, and dyspnoea mainly when drinking. From his 1st day of life we observed generalized muscular hypotonia and a tendency for hyperextension at neurological examination.

Diagnosis of salivary gland disease using ultrasound and sialography: a comparison.

Thirty-one patients with a suspected inflammatory or neoplastic lesion of a major salivary gland were investigated with ultrasound, and in 27 of them sialography was carried out in addition. The results of the diagnostic procedures were compared. Lesions of the gland parenchyma and intra and extra-glandular duct ectasia were demonstrated by ultrasound.

Tracheal and subglottic lesions following long-standing intubation. A radiological and clinical study.

A 3-year systematic study was made for subglottic and tracheal lesions of patients who had been intubated for more than 10 h (87 patients intubated for time periods ranging from 10 to 1,960 h). The radiological aspect of the lesions was studied and classified as tracheal stenosis, cartilage lesions and granulomas. The radiological analyses were performed by tracheography (14 cases), xerography, xerotomography (87 cases) and CT (2 cases).

The relation of liver fat to computed tomography numbers: a preliminary experimental study in rabbits.

The relation of liver fat content to CT number was studied in 20 rabbits (17 experimental, 3 control), where fatty degeneration was produced by carbon tetrachloride (CCl4) ingestion. Liver scanning was performed before and 2--5 days after CCl4 administration..
