How to Read a Research Paper: An Exercise in Critical Thinking in the Context of an Epidemiologic Study on Tamsulosin and the Risk of Dementia.

J Clin Psychiatry 2018 Dec 11;79(6). Epub 2018 Dec 11.

Department of Psychopharmacology, National Institute of Mental Health and Neurosciences, Bangalore, India.

A recent study of the relationship between tamsulosin and dementia found that, in propensity score-matched analyses that adjusted for measured risk factors for dementia, the use of tamsulosin to treat benign prostatic hyperplasia (BPH) was associated with a small but significant increase in the risk of incident dementia relative to untreated BPH, BPH treated with the 5α-reductase inhibitors dutasteride and finasteride, and BPH treated with the α adrenoceptor blockers doxazosin, terazosin, and alfuzosin. The choice of control groups addressed confounding by indication, confounding by disease severity, and confounding by pharmacologic drug class. The authors of the study provided a wealth of detail in their main paper and in supplementary materials, allowing an almost forensic examination of the findings. Read More

S. A. Richardson, Dr. A. M. Eissa, Department of Chemistry, University of Warwick, Coventry, CV4 7AL, UK.

A novel strategy for the surface functionalization of emulsion-templated highly porous (polyHIPE) materials as well as its application to in vitro 3D cell culture is presented. A heterobifunctional linker that consists of an amine-reactive N-hydroxysuccinimide ester and a photoactivatable nitrophenyl azide, N-sulfosuccinimidyl-6-(4'-azido-2'-nitrophenylamino)hexanoate (sulfo-SANPAH), is utilized to functionalize polyHIPE surfaces. The ability to conjugate a range of compounds (6-aminofluorescein, heptafluorobutylamine, poly(ethylene glycol) bis-amine, and fibronectin) to the polyHIPE surface is demonstrated using fluorescence imaging, FTIR spectroscopy, and X-ray photoelectron spectroscopy.

In-Phase and Opposed-Phase Imaging: Applications of Chemical Shift and Magnetic Susceptibility in the Chest and Abdomen.

Radiographics 2018 Dec 14:180043. Epub 2018 Dec 14.

From the Mallinckrodt Institute of Radiology, Washington University School of Medicine, 510 S Kingshighway Blvd, Campus Box 8131, St Louis, MO 63110.

For the radiologist performing body MRI, chemical shift imaging is a unique tool available to investigate the cellular composition of tissue. By leveraging the inherent difference in resonant frequency between water and fat protons that is due to their local chemical environment, chemical shift image acquisition can be timed to image water and fat protons when their collective signals are in phase or out of phase, to determine the relative amount of fat signal and water signal within an individual voxel. Loss of signal intensity between the in-phase and opposed-phase MR images indicates intravoxel lipid and can be used to make definitive benign diagnoses, characterize the tissue composition of solid organs, and serve as an adjunct imaging feature aiding in the diagnosis of a variety of benign and malignant processes in the chest and abdomen.

Uncommon presentation of postcardiac injury syndrome induced by radiofrequency catheter ablation for atrial fibrillation: Only pulmonary parenchymal inflammation.

J Cardiol Cases 2016 Jul 29;14(1):17-20. Epub 2016 Apr 29.

Department of Cardiovascular Sciences, First Affiliated Hospital, School of Medicine, Zhejiang University, Hangzhou, China.

Postcardiac injury syndrome (PCIS) is characterized by the appearance of pericardial, pleural, or pulmonary parenchymal inflammation following a cardiac operation. The autoimmune disorder is characterized by eosinophilia, pleuritic chest pain, pleural, and pericardial effusion. It is a troublesome complication, which may prolong hospital stay and lead to severe and life-threatening conditions. Read More

Transient right bundle branch block: A rare manifestation in cardiac contusion.

J Cardiol Cases 2016 Apr 11;13(4):121-124. Epub 2016 Feb 11.

Department of Medicine, Division of Cardiology, New York University School of Medicine, New York, NY, USA.

Transient right bundle branch block following blunt cardiac injury is a known but under-recognized manifestation of cardiac contusion. The first case documented in the medical literature occurred in 1952 in a 22-year-old man who was thrown from a motorcycle. Due to their relatively anterior location, the right ventricle and right bundle branch are at particular risk of injury in contusion. Read More

Complete occlusion of the left main trunk coronary artery by a cardiac papillary fibroelastoma in a hemodynamically unstable patient.

J Cardiol Cases 2016 Apr 29;13(4):97-100. Epub 2015 Dec 29.

Division of Emergency and Critical Care Medicine, Department of Acute Medicine, Nihon University School of Medicine, Tokyo, Japan.

Papillary fibroelastomas are benign cardiac tumors with high embolic potential. The majority of cases of complete obstruction of the left main trunk (LMT) of the coronary artery are diagnosed via autopsy following sudden death; survival is rare in this setting. We present the case of a 60-year-old woman who underwent stent placement in the LMT three years prior to developing chest pain and cold sweats. Read More

Corticosteroid prophylaxis for fetal immaturity in a pregnant patient with atrial myxoma.

J Cardiol Cases 2016 Mar 19;13(3):67-69. Epub 2015 Sep 19.

Department of Cardiac Surgery, "G. D'Annunzio" University, Chieti, Pescara, Italy.

We report a case of a woman at 32nd gestational week, admitted for resting dyspnea, showing left atrial (LA) myxoma. Cardiac myxomas are the most common primary benign tumors of the heart. The incidence of cardiac myxomas diagnosed in pregnancy is extremely low. Read More

Primary cardiac malignant fibrous histiocytoma with abdominal wall metastasis.

J Cardiol Cases 2015 Nov 25;12(5):139-142. Epub 2015 Jun 25.

Division of Neurosurgery, Tane General Hospital, Osaka, Japan.

We present a rare case of cardiac malignant fibrous histiocytoma (MFH; undifferentiated pleomorphic sarcoma); to date, fewer than 100 cases of cardiac MFH have been reported. In this case, transthoracic echocardiography revealed cardiac tumors in the left atrium (LA) of a 53-year-old woman with a 3-month history of worsening dyspnea; the largest tumor was found to protrude through the mitral valve in diastole, causing stenosis. Three of the four tumors were resected during emergency surgery; however, the residual tumor extension into the left pulmonary vein could not be removed. Read More

A surgical case of papillary fibroelastoma originating from the left atrial ridge.

J Cardiol Cases 2015 Jan 6;11(1):18-20. Epub 2014 Oct 6.

Department of Cardiovascular Surgery, St. Mary's Hospital, Kurume City, Fukuoka, Japan.

Papillary fibroelastomas are benign cardiac tumors with high embolic tendency, and usually originate from the cardiac valve. We report the case of a 49-year-old man who experienced sudden right hemiplegia and aphasia. Transesophageal echocardiography indicated a swinging tumor originating from the left atrial ridge between the orifice of the left atrial appendage and the anterolateral mitral annulus. Read More
