The 12-lead surface electrocardiogram (ECG) is of great importance for the diagnostics of cardiac arrhythmias. For the correct and systematic analysis it has a sensitivity and specificity for the correct diagnosis of supraventricular tachycardia or ventricular tachycardia of more than 95%. Nevertheless, the assessment of cardiac rhythm disorders is difficult for many physicians. In this way errors can occur, frequently due to a non-systematic analysis of the ECG; therefore, the aim of this article is to present the techniques and the necessary knowledge for assessment of the most frequent bradycardiac and tachycardiac heart rhythm disorders...

BACKGROUND: Root canal anatomy is a complex entity. The main objective of root canal treatment is to get rid of the infection and have a good apical and coronal seal with an appropriate filling. Inability to achieve thorough cleaning and shaping followed by three-dimensional obturation of the root canal system usually causes root canal treatment failure. For this reason, clinicians should be aware of these anatomical variations to achieve successful treatment. AIM: The aim of this article is to report on the successful treatment and follow-up of mandibular first molar with additional middle mesial (MM) and middle distal (MD) canals...

As obesity prevalence increases worldwide, healthcare professionals are often faced with challenging cases associated with massive obesity. A 33-year-old woman (weight 342 kg, body mass index = 100 kg/m²) presented with respiratory failure, limb edema and ascites. Abdominal CT scan became feasible after initial weight loss and showed a large pelvic mass in contact with the left ovary. The surgical removal performed despite a high-risk profile led to the diagnosis of a giant mucinous borderline tumor whose growth was due to delayed care and responsible for multiple severe complications: sepsis, anemia, esophagitis, constipation, anorexia due to mechanical compression, undernutrition, sarcopenia and lower limb edema contributing to a severe disability...

BACKGROUND: Diagnostic outcomes in eating disorder (ED) risk reduction trials are important but rarely reported. METHODS: An online pragmatic randomized-controlled trial was conducted with young-adult women in Australia and New Zealand seeking to improve their body image. Media Smart-Targeted (MS-T) was a 9-module program released weekly while control participants received tips for positive body image. Eating Disorder Examination-Questionnaire (EDE-Q) scores from baseline and 12-month follow-up were used to investigate two outcomes: ED onset in those who were asymptomatic at baseline (prevention effects); and, ED remission in those who met diagnosis at baseline (treatment effects)...

OBJECTIVE: Anatomy of the posterior ascending artery (PAA) has been well documented. The PAA forms an apical arcade which supplies the small branches to the tip of the dens. However, morphometrics of this artery such as diameter and distance from the midline which could be applied to the diagnosis and surgical procedure is scant. We aimed to investigate the anatomy of the PAA in order to apply to surgical procedure such as C2 pedicle screw placement. METHODS: Ten sides from five Caucasian cadaveric heads in which red latex was injected were used...

INTRODUCTION: Intrarenal inflammation has been implicated in the pathogenesis of nephrolithiasis, with prior work showing increased urine levels of IL-6, IL-8, and CCL-2 in stone patients. However, no studies have assessed for inflammation in the renal papillae. We sought to characterize novel papillary tip and urinary biomarkers in stone patients. METHODS: 92 patients with nephrolithiasis undergoing percutaneous nephrolithotomy were enrolled. Papillary tip biopsies, kidney urine, and bladder urine were collected, as well as voided urine from 8 healthy volunteers...

Since 1998 pulmonary hypertension has been clinically classified into five well-defined, distinct categories. A definitive diagnosis of pulmonary hypertension requires the invasive confirmation of an elevated mean pulmonary artery pressure of 25 mm Hg or above during a right heart catheterization. From a hemodynamic point of view, pulmonary hypertension is classified into precapillary and postcapillary pulmonary hypertension on the basis of a pulmonary artery wedge pressure threshold value of 15 mm Hg. Pulmonary vascular resistance is better characterized by multi-point pressure/flow measurements than by single-point determination...

Yong Lv, Guohong Han, Daiming Fan
Hepatic hydrothorax (HH) is a pleural effusion that develops in a patient with cirrhosis and portal hypertension in the absence of cardiopulmonary disease. Although the development of HH remains incompletely understood, the most acceptable explanation is that the pleural effusion is a result of a direct passage of ascitic fluid into the pleural cavity through a defect in the diaphragm due to the raised abdominal pressure and the negative pressure within the pleural space. Patients with HH can be asymptomatic or present with pulmonary symptoms such as shortness of breath, cough, hypoxemia, or respiratory failure associated with large pleural effusions...

Mechanical complications in peritoneal dialysis (PD), including intraluminal clogging of the PD catheter by fibrin, omentum, or blood clot, are major causes of outflow problems and, in rare cases, lead to technical failure. To visualize an intraluminal image of patients undergoing PD with ineffective ultrafiltration (UF), a SpyGlass fiber optic probe was inserted into the catheter, together with SpyBite biopsy forceps, should the removal of clogging materials be needed. Applying these transcatheter devices in 2 PD patients with unexplained UF failure led to the demonstration of omental plugging at the catheter tip in the first patient and demonstration of intraluminal blood clots in the second patient from whom clots were removal successfully...
