Classification of periodontal biotypes with the use of CBCT. A cross-sectional study.

Objectives: The aim of this study is to investigate the relationship between periodontal morphometric parameters and to develop a biotype classification based on the variables examined with the use of cone-beam computed tomography (CBCT).

Materials And Methods: Forty-two periodontally healthy subjects that underwent a CBCT examination as part of a different diagnostic procedure participated in the study. Measurements were performed on sectional images and included gingival thickness and labial bone plate thickness midbuccally, crown width to crown length ratio, bone crest to the CEJ distance and bone crest to the gingival margin distance midbuccally, and at the approximal aspects of 186 maxillary anterior teeth.

Crestal bone resorption after the application of two periodontal surgical techniques: a randomized, controlled clinical trial.

Aim: To radiographically assess, by means of digital subtraction radiography, crestal bone loss following two periodontal surgical techniques, over a period of 6 months.

Material And Methods: A total of 30 chronic periodontitis patients participated in this randomized controlled clinical trial and were separated into two groups. Modified Widman flap was applied in the control group and apically positioned flap, without intervention to the bone, in the experimental group.

An m-Health monitoring system for children with suspected arrhythmias.

Advances in wireless communications and networking technologies as well as computer and medical technologies, enable the development of small size, power efficient and more reliable medical multi-parameter recording systems, which can be used for continuous monitoring of patients. Through this paper we present the basic architecture and initial development steps of an m-Health monitoring system that will be used in order to monitor children with suspected cardiac arrhythmias. The proposed system will be based on sensor networks, in order to monitor a subject while being in a predefined area like his/her house; while a module based on PDAs and wearable ECG recorders will be used in order to extent the coverage outside the patient's house.

Chronic hyponatremia due to reset osmostat in a patient with colon cancer.

A 62-year-old man with colon cancer who presented with hyponatremia is described. Volume depletion, renal failure, and cardiac, adrenal, hepatic, and thyroid diseases were excluded as causes of hyponatremia. The urine sodium concentration was repeatedly increased, suggesting the presence of the syndrome of inappropriate antidiuretic hormone secretion.
