Electrochromic graduated filters with symmetric electrode configuration.

Graduated optical filters are commonly used for spatial image control as they are capable of darkening the overexposed parts of the image specifically. However, they lack flexibility because each filter has a fixed transmission distribution. We herein present a fully controllable graduated filter based on the electrochromic device.

Following in the footsteps of Hippocrates-interrelation between the incidence of odontogenic abscess and meteorological parameters.

Objectives: Although many physicians in daily practice assume a connection between odontogenic infections and meteorological parameters, this has not yet been scientifically proven. Therefore, the aim of the present study was to evaluate the incidence of odontogenic abscess (OA) in relation to outdoor temperature and atmospheric pressure.

Patients And Methods: An analysis of patients with an odontogenic abscess who presented at the emergency department within a period of 24 months was performed.

Odontogenic Abscess-Related Emergency Hospital Admissions: A Retrospective Data Analysis of 120 Children and Young People Requiring Surgical Drainage.

Introduction: Even today, despite medical progress and intensive health education, odontogenic infections leading to surgical intervention and hospitalization are common in children and young people. The aim of this study was to give a detailed overview of clinical and economic data on children and young people treated and hospitalized due to an odontogenic abscess at a tertiary university hospital.

Methods: A single-center retrospective analysis of patients under the age of 18 years who were hospitalized and surgically treated under local or general anesthesia for an odontogenic abscess during a period of 24 months was performed.

HealthDesk for Hemophilia: an interactive computer and communications system for chronic illness self-management.

HealthDesk for Hemophilia is an interactive computer software application designed on the premise that successful chronic illness self-management requires information, self-care skills, on-going communication with health care providers, and user-friendly record keeping. The software was pilot tested for six months in the homes of eight hemophilia patients. The purpose of the pilot was to assess the impact of HealthDesk for Hemophilia on patient satisfaction, patient-provider communication, and user confidence in chronic illness self-management.

Anticonvulsant-induced changes in tissue manganese, zinc, copper, and iron concentrations in Wistar rats.

Human epileptics have been reported to have low blood manganese (Mn) concentrations in comparison to nonepileptics, an observation that is important because Mn deficiency can increase seizure susceptibility in experimental animals. Factors that have been suggested to contribute to the low blood Mn levels in epileptics include anticonvulsant use, seizure-induced tissue redistribution of Mn, and genetics; in the present study, the first of these possibilities was tested. Wistar rats were fed semipurified diets containing diphenylhydantoin ([DPH] 3 g/kg diet), phenobarbital ([PB] 2 g/kg diet), or primidone ([PRIM] 3 g/kg diet) for 7 weeks, at which time they were killed and tissues collected and analyzed for Mn, zinc (Zn), copper (Cu), and iron (Fe) concentrations.
