Biochemical profiling study in umbilical cord blood in mothers with metabolic disorders.

Background: During pregnancy metabolic disorders that affect differently the fetus, are known. These could be early or late disorders.

Objectives: To analyze different biochemical parameters in umbilical cord blood (UCB) of healthy and pathological newborns from mothers with metabolic disorders.

Structural changes in endocrine pancreas of male Wistar rats due to chronic cola drink consumption. Role of PDX-1.

The objective of this work was to analyze the structural changes of the pancreatic islets in rats, after 6 month consuming regular and light cola for 6 months. Also, we have analyzed the possible role of PDX-1 in that process. Finally, with the available knowledge, we propose a general working hypothesis that explains the succession of phenomena observed.

[Microbiological analysis of the maternal genital tract and umbilical cord blood and its association with neonatal damage].

The etiology leading to neonatal damage is multifactorial, being genital infections one of the causes. The objective of the study was to identify microorganisms of the maternal genital tract that are associated with neonatal damage, in order to prevent future perinatal complications. Seven hundred and eleven pregnant patients attended their prenatal control during the period January 2010-July 2013.

Pulmonary hypertension and pregnancy outcomes: data from the Registry Of Pregnancy and Cardiac Disease (ROPAC) of the European Society of Cardiology.

Aims: To describe the outcomes of pregnancy in women with pulmonary hypertension.

Methods And Results: In 2007 the European Registry on Pregnancy and Heart Disease was initiated by the European Society of Cardiology. Consecutive patients with all forms of cardiovascular disease, presenting with pregnancy, were enrolled with the aim of investigating the pregnancy outcomes.

Short-term amiodarone therapy after reversion of persistent atrial fibrillation reduces recurrences at 18 months.

Background: The aim of this study was to compare the outcome of 3 months vs. 18 months of amiodarone treatment after atrial fibrillation (AF) conversion in patients who experienced the first episode of persistent AF.

Methods: We included 51 patients who experienced the first episode of persistent AF receiving amiodarone (600 mg) daily for 4-6 weeks.

[Right ventricular outflow tachycardia during pregnancy].

During pregnancy, there is an increase in metabolism, oxygen consumption, heart rate, stroke volume, cardiac output, blood volume and a decrease in blood pressure and peripheral resistance. Studies have shown that during this period the occurrence of cardiac arrhythmias is not uncommon. Fortunately, malignant arrhythmias are rare.

Leflunomide-induced pulmonary hypertension in a young woman with rheumatoid arthritis: a case report.

Leflunomide, a disease-modifying antirheumatic drug, has been shown to be effective in the management of rheumatoid arthritis (RA). Among other side effects, systemic hypertension has been described, and also a case of possible pulmonary hypertension (PH) has been reported. Symptomatic PH in RA is rare.

[Sudden death due to commotio cordis associated to non compacted myocardium].

Non compact of the left ventricular myocardium is a rare congenital cardiomyopathy characterized by the presence of multiple and prominent deep trabeculations in the ventricular wall, that define recesses communicated with the main ventricular chamber. This is a condition with low incidence and prevalence, diagnosed through imaging techniques such as Doppler echocardiogram (DE), multi-slice computed tomography (MSCT) or magnetic resonance imaging (MRI). Clinically, it may be asymptomatic or manifested by cardiac arrhythmias, heart failure or thromboembolism.

Brugada type 1 electrocardiographic pattern induced by severe hyponatremia.

Brugada syndrome is characterized electrocardiographically by ST segment elevation in the right precordial leads, followed by a negative T wave unrelated to ischemia, electrolyte disturbance or drug effects and prone to rapid polymorphic ventricular tachycardia capable of degenerating into ventricular fibrillation. The ECG pattern may be dynamic and is often concealed. Sodium channel blockers, drugs, electrolyte imbalances, fever and several other clinical circumstances are recognized inducers of a Brugada type 1 ECG in susceptible patients.

[Hypothyroidism, dilated cardiomyopathy and nephrotic syndrome during pregnancy].

Hypothyroidism during pregnancy is infrequent, but its presence is associated with maternal and fetal complications. We present the case of a young pregnant woman with no previous history of cardiovascular disease, who consulted for orthopnea, chest pain and edema in both legs. Laboratory tests demonstrated a hypothyroid condition and a nephrotic syndrome with renal failure.

[Young woman with hyperthyroidism associated with severe tricuspid regurgitation].

Cardiovascular manifestations of hyperthyroidism are frequent and sometimes are relevant in the clinical picture. Usually an hyperdynamic circulatory state hallmarks the disease with low peripheral resistance, increased intravascular volume and cardiac output. However, right chamber dilatation with tricuspid valve regurgitation and cardiac failure are unusual.

[Generalized eruptive histiocytoma].

We present the case of a 64-year-old male who developed multiple asymptomatic papules over a four-month period, distributed symmetrically on the trunk and proximal regions of the limbs, while the scalp, palms, soles and mucous membranes were spared. The lesions were discrete papules, brownish-erythematous, rounded, ranging from slightly raised to hemispherical, from 1 to 3 mm in diameter and firm to the touch. Clinical, histopathological, immunohistochemical and ultrastructural studies were consistent with generalized eruptive histiocytoma.

[Pigmented apocrine hidradenoma].

Apocrine hidradenoma is a benign adnexal neoplasm. It has no specific site predilection, and usually affects middle-aged people. The same as other tumors of the sweat glands, there is a pigmented variety.

[Poroid hidradenoma].

Poroid hidradenoma is a recently described variant of eccrine poroma. This neoplasm presents structural findings of hidradenoma (solid and cystic areas) and cytological characteristics of poromas (poroid and cuticular cells, the latter showing ductal differentiation). We present a case of poroid hidradenoma in a 74-year-old woman, who consulted her physician because of a nodular lesion on the left buttock.

Pharmacologic reversion of persistent atrial fibrillation with amiodarone predicts long-term sinus rhythm maintenance.

Objective: The study analyzed the role of different variables that determine long-term sinus rhythm maintenance in patients with persistent atrial fibrillation who are treated with amiodarone.

Background: It has been recognized that different factors influence long-term sinus rhythm preservation after the conversion of persistent atrial fibrillation. Although the duration of the arrhythmia appears to be the most important factor, consistent information regarding the role of the mode of arrhythmia conversion (pharmacologic or electric) is still lacking.
