INTRODUCTION: Fetal growth restriction is associated with short-term and long-term mortality and morbidity. We hypothesized that adverse outcome in children with fetal growth restriction at primary school age is associated with fetoplacental circulatory abnormalities. MATERIAL AND METHODS: Comprehensive ultrasonographic assessment of fetoplacental hemodynamics was performed in 72 growth-restricted fetuses prenatally, and short-term outcome data were collected. At the median age of 9 years, mortality and morbidity were determined using medical charts and questionnaires...

This case report describes a 37-year-old female who was admitted to our Emergency Department because of shortness of breath. On physical examination, she had dyspnea and tachycardia and blood pressure was 80/50 mmHg with a pulsus paradoxus of 22 mmHg. Neck veins were distended, heart sounds were distant, and dullness was found on both lung bases. Her chest X-ray revealed bilateral pleural effusion and cardiomegaly. On both computed tomography and echocardiography the heart was of normal size and a large pericardial effusion was noted...

We present the case of a patient who came to our attention for enlargement of the cardiac silhouette on chest X-ray. Echocardiography showed moderate diastolic overload of both ventricles with enhanced cardiac output without valvular disease or cardiac shunt that could account for this cardiomegaly. A subsequent abdominal echocardiographic exploration showed an angiomatous transformation of the liver due to diffuse lacunar enlargement of hepatic portal vein branches and arterial-venous shunts. Computed tomography and magnetic resonance imaging confirmed the echocardiographic findings...

This report describes 2 sheep with enzootic calcinosis characterized by abnormal cardiovascular and respiratory findings and ascites causing abdominal distension. Both sheep were anorexic and listless and had increased heart and respiratory rates. Auscultation of the heart revealed a gallop rhythm in sheep 1 and a loud systolic heart murmur in sheep 2. The activities of liver enzymes were severely increased in both sheep. Abdominal ultrasonography showed severe ascites and congestion of the liver and caudal vena cava...

OBJECTIVES: Convolutional neural networks (CNNs) are a subtype of artificial neural network that have shown strong performance in computer vision tasks including image classification. To date, there has been limited application of CNNs to chest radiographs, the most frequently performed medical imaging study. We hypothesize CNNs can learn to classify frontal chest radiographs according to common findings from a sufficiently large data set. MATERIALS AND METHODS: Our institution's research ethics board approved a single-center retrospective review of 35,038 adult posterior-anterior chest radiographs and final reports performed between 2005 and 2015 (56% men, average age of 56, patient type: 24% inpatient, 39% outpatient, 37% emergency department) with a waiver for informed consent...

A previously healthy 3-year-old boy presented to the emergency department with abdominal pain, fever, and emesis. Laboratory and radiologic evaluation for causes of acute abdomen were negative; however, review of the abdominal x-ray demonstrated cardiomegaly with the subsequent diagnosis of pericardial cyst by echocardiogram and computed tomography. The patient underwent surgical decompression and attempted removal of the cystic structure revealing that the cyst originated from the epicardium. His abdominal pain and fever resolved postoperatively and he completed a 3-week course of ceftriaxone for treatment of Propionibacterium acnes infected congenital epicardial cyst...

Pulmonary arteriovenous malformations are rare vascular anomalies of the lung, only a few cases of which have been diagnosed prenatally. The diagnostic clue for prenatal diagnosis was cardiomegaly with a particularly enlarged left atrium. All previous cases of pulmonary arteriovenous malformations diagnosed prenatally have been reported as an isolated anomaly or in association with simple heart defects. We here describe the first case of a pulmonary arteriovenous malformation with a complex heart defect that was diagnosed prenatally at 21...

BACKGROUND: The adenosine triphosphate-sensitive potassium (KATP) channel opener diazoxide (DZX) prevents myocyte volume derangement and reduced contractility secondary to stress. KATP channels are composed of pore-forming (Kir6.1 or Kir6.2) and regulatory (sulfonylurea receptor, SUR1 or SUR2) subunits. Gain of function (GOF) of Kir6.1 subunits has been implicated in cardiac pathology in Cantu syndrome in humans (cardiomegaly, lymphedema, and pericardial effusions). We hypothesized that GOF of Kir6...

INTRODUCTION: The endothelin system, for its vasoconstrictor action, is related to the development of essential hypertension (HTAe). The polymorphism analysis of their genes represents a new approach to the study of this disease. We propose to analyze the interaction between stages of essential hypertension (HTAe) and risk factors with polymorphisms 138ex1 ins/del A gene endothelin-1 (ET-1) and H323H receptor gene A ET-1 (ETRA). PATIENTS AND METHODS: We included 300 patients of both sexes, unrelated, who consecutively attended the clinic hypertension medical service...

Multiple giant aneurysms involving the coronary arteries are uncommon and rarely reported. In the presented case, a 63-year-old man with poorly controlled hypertension died suddenly. Gross autopsy examination showed multiple giant thrombus-filled coronary artery aneurysms, atherosclerotic coronary artery disease, and cardiomegaly. Histological sections of the coronary aneurysms showed atherosclerotic changes with both organized and fresh thrombus. Giant coronary aneurysm is defined as a segmental enlargement of a coronary artery with a diameter exceeding 20 mm or more...

A 6-year-old, male, mongrel dog was presented for acute onset of dyspnea and cough. At admission, the dog was cachectic and severely depressed. The electrocardiogram showed a sinus rhythm conducted with left bundle truncular branch block and interrupted by frequent multiform ventricular ectopic beats organized in allorhythmias. Thoracic radiographs revealed a marked cardiomegaly with perihilar edema, whereas transthoracic echocardiography revealed a dilated cardiomyopathy with segmental dyskinesis. Furosemide, enalapril, pimobendan, and mexiletine were prescribed, and a Holter was scheduled after resolution of congestive heart failure...

The Townes mouse model of homozygous sickle cell disease (SS) has emerged as the major experimental model for studying pathophysiological mechanisms of human sickle cell disease (SCD). We therefore investigated hematological and hemorheological parameters as well as organ-specific inflammatory and oxidative stress molecular profiles in these animals in steady state conditions. Evidences of SCD-related intravascular hemolysis, impaired red blood cell (RBC) deformability, leukocytosis and altered plasma nitric oxide byproducts (NOx) level were found in the SS mice...

The authors present a case of carnitine transporter deficiency, which was unmasked after an episode of respiratory distress resistant to treatment with bronchodilators. Chest radiograph showed cardiomegaly; electrocardiogram showed left ventricular hypertrophy and echocardiography revealed dilated cardiomyopathy. Heart failure therapy was initiated and metabolic screening was requested, as family history was indicative of inborn errors of metabolism. Very low levels of free carnitine and carnitine esters in blood were found and genetic testing confirmed the diagnosis of carnitine transporter deficiency...

We report a case who presented to us with dyspnea and was found to have ML in the absence of steroid use, diabetes, Cushing syndrome and obesity. This case provides an important differential diagnosis in a patient presenting with dyspnea widened mediastinum and cardiomegaly. This is probably among very few cases of ML with dyslipidemia.

A 49-year-old man visiting New Orleans from Chile comes to the hospital complaining of exertional dyspnea for 2 months with the more recent onset of ankle edema. He is a slender man with a blood pressure of 91/60 mmHg, crackles at both lung bases, and markedly distended neck veins. His cardiac rhythm is irregular. A soft murmur of mitral regurgitation and a soft S-3 are heard at the left ventricular apex. All four pedal pulses are easily palpable. Epigastric tenderness is noted on palpation; although the patient has a history of peptic ulcer disease, the tenderness is probably due to an enlarged left lobe of his liver, the result of hepatic congestion from his heart failure...

Case 1 A 60-year-old African American man presented with a medical history of morbid obesity (weighing more than 550 lb), benign prostatic hyperplasia, hyperlipidemia, gynecomastia, atrial fibrillation, hypertension, chronic obstructive pulmonary disease, psoriasis, sleep apnea, and cardiomegaly. His size has limited his ability to clean himself properly. He experiences chronic and recurrent skin irritation and cellulitis possibly secondary to intertriginous superinfection, lymphedema, and venous stasis. On examination, his abdomen showed heavy skinfolding with hyperpigmentation, cobblestone and velvety changes, thickening and fibrotic induration of the skin, focal areas of redness, and tenderness on palpation (Figure 1A and 1B)...

INTRODUCTION: Differences in systolic blood pressure reading between arms are common but could signal trouble if the discrepancy is significant. Early detection of aortic dissection could invariably determine patient's survivability. Hence, a high index of suspicion with prompt diagnostic imaging is vital for accurate diagnosis.

Vitamin D is implicated in the etiology of cancers of the gastrointestinal tract, usually characterized by alteration in the APC/β-catenin/TCF tumor suppressor pathway. The vitamin D receptor (VDR) is also implicated in cardiovascular and skin diseases as well as in immunity. Activated VDR can indirectly alter β-catenin nuclear localization and directly suppress β-catenin/TCF mediated transcriptional activity. We treated VDR null mice with the carcinogen azoxymethane (AOM) and generated mice bearing a mutated APC (hypomorph) on a VDR null background (Apc1638N/+Vdr-/-)...

BACKGROUND AND RATIONALE: Respiratory system involvement in scrub typhus is seen in 20-72% of patients. In endemic areas, good understanding and familiarity with the various radiologic findings of scrub typhus are essential in identifying pulmonary complications. MATERIALS AND METHODS: Patients admitted to a tertiary care center with scrub typhus between October 2012 and September 2013 and had a chest X ray done were included in the analysis. Details and radiographic findings were noted and factors associated with abnormal X-rays were analyzed...
