Electrical Cardioversion: A Review
Max E Valentinuzzi, EE, PhD and Luis Aguinaga Arriascu, MD
Article Type: Review Article | First Published: January 23, 2020
Atrial fibrillation (AF), not to be confused with atrial flutter, is the term used to describe an irregular or abnormal heart rate. While AF and atrial flutter are similar, AF has more serious health implications such as an increased risk of having a stroke or a blood clot (thrombosis). The resting heart rate of someone without AF is usually between 60 and 100 beats per minute but this number is usually over 100 in AF. It is usually the result of an underlying condition such as hypertension (high blood pressure) or having an overactive thyroid but may develop for no known reason. In this circu...

Leptospirosis is an infectious-contagious zoonosis caused by gram-negative bacteria, a spirochete of the genus Leptospira. It is largely related to high rainfall levels, accumulation of litter, presence of rodents and lack of basic sanitation. The present study aimed to verify the level of knowledge of the population and the risk factors of leptospirosis in a region frequently affected by floods in Blumenau/Santa Catarina/Brazil, as well as the control of rodents carried out by the interviewees. The data were collected through questionnaires applied to a sample of 270 interviewees and the resu...
Accuracy of Orthopedic Shoulder Test in Detecting Rotator Cuff Tears and Retears: A Narrative Review
Brian H Goldman, DO, Alejandro Carmona-Casillas, BS, Greg Galvin, DO, Jorge Benito, DO, Phong Truong, DO and Pedro J Tort-Saade, MD
Article Type: Narrative Review Article | First Published: January 23, 2020
The purpose of this review is to discuss the accuracy of orthopedic tests in detecting rotator cuff tears and retears, while developing new, more sensitive and specific clinical exam tools. With the ever-increasing population and consequent increased incidence of shoulder pathology, there is a vertical trend in medical cost as physical diagnosis is evermore substituted by imaging diagnosis. Unfortunately, clinical examination maneuvers have demonstrated variable specificity and sensitivity for primary rotator cuff tears, leading to the dependance of imaging modalities. Currently, there is no c...
Effect of RF Fields during Pulse on Rotational Diffusion: Influence on Spectral Density
Dennis J Sorce
Article Type: Research Article | First Published: January 13, 2020
The effect of the applied RF field in an NMR experiment on the magnitude of the Spectral Density for a Dipolar Relaxation Mechanism is demonstrated theoretically. The effect is shown with Sin Cos Pulse as a concrete example. The order of magnitude of the magnetic moment where these effects will be significant for typical Rf amplitude values is derived. The effect may be of utility in providing an alternate method of control for MRI Tissue Contrast applications with further development. In contemporary NMR methodologies, it is common to find experimental scenarios where the relaxation of the ma...
Wunderlich Syndrome: A Rare Syndrome Caused by a Polyarteritis Nodosa
Leandro Tristao Abi-Ramia de Moraes, Monica Arnaldi and Sergio Furlan
Article Type: Case Report | First Published: December 30, 2019
Wünderlich syndrome (WS) is a rare condition, in which spontaneous nontraumatic renal hemorrhage occurs into the subcapsular and perirenal spaces and was described for the first time by Bonet in 1700. The etiology of the entity is very diverse, including benign or malign neoplasms, vascular diseases, infectious and inflammatory kidney diseases, and could be combined with some diseases. Clinically the syndrome is characterized by the classic Lenk's triad. We describe a case of WS in a 37-years-old woman with loss of strength in the right superior limb for three months. After admission in the h...

Obstructive sleep apnea (OSA) is an important public health concern with numerous consequences at the societal level, including motor vehicle accidents, increased cardiovascular morbidity, metabolic dysfunction, and behavioral and cognitive deficit. OSA is characterized by a decrease in, or complete cessation of, airflow despite ongoing efforts to breathe, and is related to oxygen desaturation and sleep fragmentation. The prevalence of OSA has been estimated at 14% in men and 5% in women...
Comparative Study of the Online Over-The-Counter Hair Loss Products

There are tremendous amount of the overthe- counter (OTC) hair loss products available online and widely purchase all over the world by many consumers. We conducted this study to evaluate some popular and widely used OTC hair loss products that are introduced by famous online retailer websites. Most of hair loss products are natural products, vitamins, minerals, amino acids and proteins. The products found in the top sellers are different between the online retailers regarding their type, side, dosage forms and prices. Minoxidil, the only FDA approved OTC hair loss drug, is found only in the l...
Surgical Management of Growing Patients through Orthognathic Surgery: A Review

Article Type: Review article | First Published: January 10, 2020
Facial aesthetics has a meaningful relationship with the capacity of people to form interpersonal relationships, which can lead to cases of harassment when there are severe facial disharmonies. For a long time, orthognathic surgery has been indicated in patients whose growth has ended in order to achieve more stable and predictable results over time. However, there are cases where psychosocial stress due to dentofacial deformities makes necessary to intervene patients at a younger age. This review article aims to describe the surgical management and stability of growing patients through orthog...
