Transitory force decrease following a sudden reduction in stimulation frequency in motor units of rat medial gastrocnemius.

Effects of a sudden decrease in the stimulation frequency for motor unit force were studied in rat medial gastrocnemius. For 161 functionally isolated single motor units of three types (S, FR, FF), unfused tetanic contractions were evoked by three-phase trains of stimuli (low-high-low frequency). The course of the tetanus at the onset of the third phase of the force recording was analyzed in tetani with variable fusion degree.

The Impact of Brain Breaks Classroom-Based Physical Activities on Attitudes toward Physical Activity in Polish School Children in Third to Fifth Grade.

The purpose of this study was to examine the effectiveness of the Brain Breaks® Physical Activity Solutions in changing attitudes toward physical activity of school children in a community in Poland. In 2015, a sample of 326 pupils aged 9-11 years old from 19 classes at three selected primary schools were randomly assigned to control and experimental groups within the study. During the classes, children in the experimental group performed physical activities two times per day in three to five minutes using Brain Breaks® videos for four months, while the control group did not use the videos during the test period.

[Terminology concerning intravenous ports].

Ports are more and more often applied with patients requiring the permanent intravenous access, not only in the cancer treatment. Very devices, as well as procedures associated with applying them are determined in the heterogeneous way. Therefore during the last conference "Intravenous Port--implantation, care, complications" an attempt to systematize the applied terminology was made.

Translumbar inferior vena cava cannulation.

Background: The aim of the study was to review our three year experience with translumbar insertion of dialysis catheters.

Methods: In five adult patients (4 males and one female, mean age 45 yr), requiring dialysis due to end-stage chronic renal failure, the inferior vena cava was cannulated because of the impossibility of using any other approach. All procedures were performed under fluoroscopy.

[Translumbar cannulation of vena cava inferior as an alternative method of vascular access for hemodialysis].

The aim of our report is description of the first in Poland translumbar cannulation of vena cava inferior used as an alternative vascular access for hemodialysis in 62 years old patient without further access for hemodialysis and no access for peritoneal dialysis.

Successful treatment of gastric fistula following rhabdomyolysis after vertical banded gastroplasty.

Vertical banded gastroplasty is a gastric restrictive operation which has been performed with very satisfactory results in our department. We present a 46 year-old male with BMI 48, who experienced rhabdomyolsis after a VBG operation, complicated by perforation of an upper pouch ulcer and subsequent gastric fistula. Cardiac and renal failure occurred, necessitating intensive therapy with catecholamines, diuretics and hemodialysis.
