From Clinical Scenarios to the Management of Lower Urinary Tract Symptoms in Children: A Focus for the General Pediatrician.

Lower urinary tract symptoms (LUTS) are a relevant problem in the pediatric population, having a very high prevalence. Diurnal incontinence and nocturnal enuresis are surely the most frequent symptoms, presenting, respectively, in up to 30% of school-age children and up to 10% of children between 6 and 7 years. Stypsis is the most common comorbidity, and it must be considered in the management of LUTS; indeed, the treatment of constipation is curative in most cases for both incontinence and enuresis.

Reactivity and event-related potentials during attentional tests in athletes.

A series of attentional tests involving reaction times (RTs) was administered to 12 high-level young (age 17-18 years) volleyball players. During the tests, event-related potentials were recorded by electroencephalogram. In a simple reaction-time test (SRT), the subjects had to respond to a letter that appeared on a white screen.

Brief report: healed myocarditis as a cause of ventricular repolarization abnormalities in athlete's heart.

In the past myocarditis has been suggested as a possible cause of repolarization abnormalities in sportsmen, but, to our knowledge, no direct in-vivo demonstration of this relationship has so far been found. We report the cases of three professional athletes with repolarization changes at rest and/or during exercise and mild segmental wall motion anomalies in the left ventricle on echocardiography, in whom myocarditis was diagnosed by non-invasive and invasive clinical investigations, including endomyocardial biopsy. We think that probably the frequency with which myocarditis is responsible for electrocardiographic and echocardiographic abnormalities in athletes has so far been underestimated, and that caution must be employed when interpreting minor segmental wall motion abnormalities on resting and exercise echocardiograms in trained subjects as being due to athlete's hart, especially when they present with repolarization changes.

Biopsy evidence of atrial myocarditis in an athlete developing transient sinoatrial disease.

Atrial myocarditis causing transient sinoatrial disease (incessant atrial tachycardia alternating with sinoatrial pauses of up to 6 s in duration) in an athlete is reported. Diagnosis was undertaken by endomyocardial biopsy; biventricular and right atrial specimens were obtained. After a 6-month rest period, the atrial arrhythmias disappeared, and the athlete was able to resume his professional sporting activities.

Echocardiographic size of conductance vessels in athletes and sedentary people.

The purpose of the present study was to assess the size of great and medium caliber arterial and venous vessels (conductance vessels) in athletes of different sports and sedentary people. Vessel size was measured by two-dimensional echocardiography in 15 professional cyclists, 15 highly-trained long-distance runners, 15 professional volley-ball players, 10 wheelchair basketball players, 11 wheelchair distance runners and 20 sedentary controls. The following vessels were imaged and measured: aortic arch, left carotid and left subclavian artery, right pulmonary artery, abdominal aorta and mesenteric artery, superior and inferior vena cava.

[Echocardiographic visualization of the coronary arteries in endurance athletes].

Visualization of left (LCA) and right coronary artery (RCA) by two-dimensional echocardiography (2-DE) was tried in 20 highly-trained endurance athletes and 20 normal sedentary controls using multiple echo planes. On the standard parasternal short axis aortic root view, the ostium of LCA was successfully visualized in all 20 athletes (100 percent) and in 18 controls (90 percent), the left main trunk in 19 athletes (95 percent) and 14 controls (70 percent) and a distinct bifurcation of the main trunk in 4 athletes (20 percent) and 2 controls (10 percent). In another 2 athletes, the initial tract of the left anterior descending artery and of the left circumflex branch could also be identified.
