Subclinical endometritis in beef cattle in early and late postpartum: Cytology, bacteriology, haptoglobin and test strip efficiency to evaluate the evolution of the disease.

In cows, detrimental effects on fertility are mainly caused by clinical and subclinical endometritis (SEM). As demonstrated in previous work, Piedmontese cattle are affected by a higher rate of infertility and presence of SEM. The objective of this study is to assess the pattern of SEM at 30 and 60 days postpartum by evaluating the correlation between uterine cytology and microbiology, analyzing SEM consequences on reproductive career and verifying the reliability of rising inflammatory proteins - haptoglobin and the test strip test.

Left ventricular torsion in paced patients.

Background: In healthy people the left ventricle presents a counter-clockwise apical rotation and a clockwise basal rotation ending in late systole. In early systole (during isovolumic contraction) there is a fast and inverse rotation (counter-clockwise at the base and clockwise at the apex). This opposite rotation between apex and base produces the systolic torsion of the left ventricle.

Cardiac dyssynchrony quantitated by time-to-peak or temporal uniformity of strain at longitudinal, circumferential, and radial level: implications for resynchronization therapy.

Background: The standard deviation of time to peak strain (TPS-SD) has been proposed as an index of left ventricular (LV) dyssynchrony in patients to be resynchronized. However, TPS-SD is sensitive to noise, and the influence of outliers on TPS-SD is also relevant. Alternatively, dyssynchrony can be indexed by temporal uniformity of strain (TUS), whereby a time plot of regional strains, arranged for LV location, is subjected to Fourier analysis.

[Intracardiac ectopic thyroid: a report of a clinical case with a long-term follow-up].

We describe the prolonged follow-up of a 64-year-old female patient, with an ectopic intracardiac thyroid gland. The mass was first detected 14 years ago, during a routine echocardiographic examination. The patient suffered from episodes of palpitation and cardiac auscultation revealed a systolic murmur.

[Dual-chamber DDD pacing in NYHA III-IV functional class dilated cardiomyopathy: short and middle-term evaluation].

Effectiveness of dual-chamber pacing in patients with dilated cardiomyopathy is still controversial. Our study was performed: to select the most favorable individual atrioventricular (AV) delay; to compare hemodynamic short-term effects in each patient after 2 periods of DDD pacing and sinus rhythm (AV spontaneous); to assess hemodynamic long-term (1 year) effects after DDD pacing at optimum AV delay. In 1996, 9 patients (7 men, 2 women; mean age 69 +/- 5 years) with dilated cardiomyopathy (5 idiopathic, 4 ischemic), NYHA functional class III-IV, ejection fraction < 30%, end-diastolic volume > 60 ml/m2, mitral regurgitation +2/+3, PR interval > or = 200 ms, were enrolled.
