The prevalence of supraventricular arrhythmias with regard to the type and degree of left ventricular hypertrophy in patients with hypertensive heart disease.
We investigated the correlation between the type and degree of left ventricular hypertrophy and the prevalence of supraventricular arrhythmias in patients with hypertensive heart disease. ⋯ Concentric and eccentric types of left ventricular hypertrophy have a greater impact on the frequency of atrial arrhythmias. In the concentric type the prevalence of supraventricular premature beats correlates with the degree of left ventricular hypertrophy. Patients with moderate and severe concentric and eccentric left ventricular hypertrophy should be always tested using Holter monitoring and bicycle ergometry and treated with the maximum tolerable doses of antihypertensives, particularly with angiotensin-converting enzyme inhibitors/angiotensin receptor blockers.

Comparing stress levels in children aged 2-8 years and in their accompanying parents during first-time versus repeated voiding cystourethrograms.
Invasive procedures such as voiding cystourethrograms (VCUGs) cause distress in both children and their accompanying parents. The main purpose of this study was to examine whether stress levels in children and their parents differ during first-time and repeated VCUGs. The second objective was to examine the relationship between parental behavior (behavior promoting child coping and behavior promoting child distress), parental stress levels and child distress in first-time versus repeated VCUGs. ⋯ Repeated VCUGs and first-time VCUGs are both highly distressing procedures for children. Even though parental stress levels are lower during repeated VCUGs, spontaneous parental behavior proves to be ineffective or even counterproductive in reducing the child's distress. Further research into efficient counseling and training methods for parents and children undergoing VCUGs is required.

ReviewThe European surveillance activities EARSS and ESAC in the context of ABS International.
Development of resistance obstructs the successful use of antimicrobial drugs, since shortly after each and every introduction of a new antibiotic resistant pathogens have emerged. The hope of being able to reverse or at least slow down the occurrence of antibiotic resistance has led to a number of actions and initiatives. ⋯ The data generated by EARSS and ESAC are an essential prerequisite for targeted interventions to cope with the problem of antibiotic resistance. The project ABS International constitutes an impressive initiative to optimize the situation in hospitals in nine European member states.

Malariological baseline survey and in vitro antimalarial drug resistance in Gulu district, Northern Uganda.
A comprehensive, representative malaria survey has been carried out in a population of internally displaced persons (IDP) in the district of Gulu, Northern Uganda. It included 74 households and 390 persons, and covered socio-economic and environmental information, individual physical data, malaria and the drug sensitivity of Plasmodium falciparum. ⋯ P. falciparum turned out to be highly resistant to chloroquine and amodiaquine. It showed also reduced sensitivity against lumefantrine and artemisinin, obviously the result of the liberal use of the lumefantrine-artemether combination without evidence-based indication.

Abnormal pulmonary arterial pressure limits exercise capacity in patients with COPD.
Pulmonary hypertension (PH) is common in patients with chronic obstructive pulmonary disease (COPD). Mean pulmonary artery pressure (mPAP) is often only slightly elevated at rest but is increased by exercise. The purpose of this study was to determine whether abnormal pulmonary artery pressure impairs exercise capacity in patients with COPD. ⋯ In patients with COPD, abnormal pulmonary artery pressure impairs gas exchange, decreases maximum oxygen uptake during exercise and impairs exercise capacity.
