Internal validation of a telemedical system for monitoring patients with chronic respiratory diseases.

One of the most promising and innovative developments in medicine are telemedical systems. The system PulmoTel 2010 and its internal validation are presented, focusing on the system architecture, hardware, software and communication solutions. PulmoTel 2010 consists of a distant server managing users and medical devices, as well as data transmission, processing, storage and presentation.

[The evolution of ideas on surgery of frontal sinus].

The frontal sinus surgery has evolved over the past 120 years. There is an extensive literature focusing on this issue. The present review summarizes all major intranasal and external procedures in frontal sinus surgery.

Wavelet analysis of scaling properties of gastric electrical activity.

We present a novel approach to the analysis of fluctuations in human myoelectrical gastric activity measured noninvasively from the surface of the abdomen. The time intervals between successive maxima of the wavelet transformed quasi-periodic electrogastrographic waveform define the gastric rate variability (GRV) time series. By using the method of average wavelet coefficients, the statistical fluctuations in the GRV signal in healthy individuals are determined to scale in time.

[Therapeutic problems of allergy specific immunotherapy for treatment of upper respiratory tract allergies].

Allergy is an increasing problem therapeutic. The development of IgE-mediated allergy is a result of genetic and environmental factors. The severity of disease seems to be increasing.

[Classification of the rhinitis].

The development of differential diagnosis of rhinitis has multiplied their present classification. Generally, there are known two types of classifications: a) based on nasal cytology (Connell 1983); b) arising from clinical evaluations (Mygind 1985). Zeiger's work (1989) takes into consideration both types of classifications and describes them widely.
