Introduction: Hypokalemia is associated with increased morbidity and at times mortality. "Hypokalemic paralysis", particularly if recurrent, has often been considered synonymous with "hypokalemic periodic paralysis (HPP)"; however, diseases such as Gitelman syndrome (GS), Bartter syndrome (BS), and renal tubular acidosis (RTA) can have identical presentation. We have tried to explore the etiological spectrum along with epidemiological and certain clinical, biochemical, and electrophysiological features in patients with hypokalemic paralysis...

Sustainable wildlife populations depend on healthy individuals, and the approach to determine wellness of individuals is multifaceted. Blood gas analysis serves as a useful adjunctive diagnostic test for health assessment, but it is uncommonly applied to terrestrial reptiles. This study established reference intervals for venous blood gas panels in free-living eastern box turtles ( Terrapene carolina carolina , N = 102) from Illinois and Tennessee, and modeled the effects of environmental and physiologic parameters on each blood gas analyte...

BACKGROUND: Veno-venous extracorporeal membrane oxygenation (VV-ECMO) support has emerged as a valuable rescue therapy in patients with severe acute lung failure. A new bicaval dual-lumen percutaneous cannula can be instituted with a single puncture of the right internal jugular vein under image guidance (fluoroscopy and/or trans-esophageal echocardiography) to support VV-ECMO. However, malpositioning of the dual-lumen catheter can jeopardize the efficacy of the ECMO therapy. CASE REPORT: We report an emergency VV-ECMO instituted at a patient's bedside in the intensive care unit...

Pulmonary embolism (PE) is associated with approximately 100,000 deaths per year in the United States and the incidence of deep vein thrombosis/pulmonary embolism in the US is estimated at more than 350,000 cases annually (1). The diagnosis of pulmonary embolism poses a diagnostic challenge in the Emergency Department (ED), despite, validated decision rules, lab tests, and radiographic imaging (2, 3). While a simple lab test would be ideal for diagnosis, the well-known D-dimer test is, at its best, only about 54% specific (4)...

OBJECTIVES: High-frequency jet ventilation (HFJV) is a convenient method for providing ventilation during fiberoptic bronchoscopy. We describe an incipient approach of high-frequency jet ventilation via the working channel of a flexible bronchoscope for nonintubated patients who suffer from hypoxemia during bronchoscopy. The aim of this study was to test the efficacy of this incipient approach and determine the possible complications related to it. MATERIALS AND METHODS: Sixteen patients who had oxygen saturation below 70% that did not resolve with nasal oxygen for 20 s during interventional bronchoscopy were included in the study...

Two heavily O-glycosylated proteins and albumin co-purified with anti-α-galactoside (anti-Gal), the chief xenograft-rejecting antibody and anti-β-glucan (ABG) antibody isolated from human plasma by affinity chromatography on respective ligand-bearing matrices. Both antibodies and O-glycoproteins co-purified with plasma albumin eluted from albumin-specific matrix. Using components of affinity-purified antibody samples separated by electrophoresis binding of either albumin or antibody to the affinity matrix of the other or binding of O-glycoprotein to either matrix was ruled out...

BACKGROUND: Although the vertical banded gastroplasty (VBG) is effective in achieving weight loss without metabolic side effects during the first few years, late failures cause weight regain in about 20% of the patients. The laparoscopic Roux-en-Y gastric bypass (LRYGB) is the procedure of choice to convert a failed VBG. MATERIALS AND METHODS: Between August 2014 and June 2016, 37 patients (23 females and 14 males) underwent revisional LRYGBs after failed VBGs. Thirty-four patients had open VBGs and two patients had laparoscopic butterfly gastroplasties...

BACKGROUND: The diaphragm changes in COPD lead to functional inefficiency correlated to lung function loss. Muscle-fiber shortening follows lung hyperinflation, which results in a chronic mechanical disadvantage that impairs diaphragmatic mobility that worsens in COPD exacerbations. OBJECTIVES: To correlate the diaphragmatic mobility loss to COPD severity by using M-mode ultrasonography and to verify if the diaphragmatic mobility can improve after in-patient pulmonary rehabilitation...

INTRODUCTION: Neuromuscular diseases (NMD) are a group of rare heterogeneous disorders that may be accompanied by respiratory muscle weakness. The simplest measurements of respiratory muscle strength are maximum inspiratory pressure (PImax ) and maximum expiratory pressure (PEmax ) of the mouth. Inspiratory muscle weakness can also be evaluated by the sniff test (sniff nasal inspiratory pressure method). This study tested the agreements in PImax and PEmax (measured by using a plethysmograph and portable equipment) as well as the correlations of PImax and PEmax by using the sniff nasal inspiratory pressure method, lung function, and arterial blood gas parameters in subjects with NMD...

BACKGROUND: Despite clinical advances, late onset pulmonary complications in adult recipients of allogenic stem cell transplantation are a major cause of morbidity and mortality. Reported incidence and risk factors in the literature vary broadly and are partly contradictory. Identification of pre-transplant factors associated with major complications would be helpful to define individual treatment strategies and early initiation of preventive measures. AIM: To evaluate incidence and risk factors of late-onset non-infectious pulmonary complications, with special regards to small airways disease (SAD) and bronchiolitis obliterans syndrome (BOS), indicating Graft versus Host Disease (GvHD), following myeloablative vs...

Background: Considerable controversy remains about how much oxygen patients should receive during surgery. The 2016 World Health Organization (WHO) guidelines recommend that intubated patients receive a fractional inspired oxygen concentration (FIO2 ) of 0.8 throughout abdominal surgery to reduce the risk of surgical site infection. However, this recommendation has been widely criticised by anaesthetists and evidence from other clinical contexts has suggested that giving a high concentration of oxygen might worsen patient outcomes...

Taking arterial blood gases (ABG) is an essential part of the diagnosis and management of critically ill patients. An arterial blood sample is collected from an artery, primarily to determine the ABGs. Health professionals should only undertake this if the procedure is in the legal scope of practice for their profession in their country, and they have demonstrated skilled, proficient, safe practice after formal training. Blood samples can be obtained via an arterial catheter inserted into an artery or percutaneously by using a needle to directly puncture into the artery...

Severe eating disorders characterized by repetitive episodes of purging and vomiting can occasionally trigger acute kidney injury. However, interstitial nephritis induced by episodes of repeated vomiting has rarely been reported, and the pathophysiology of this entity remains unknown. A 26-year-old man was admitted to our hospital because of known hypokalemia. His serum electrolyte profile showed: sodium 133 mEq/L, potassium 2.6 mEq/L, chloride 72 mEq/L, total carbon dioxide 50 mEq/L, blood urea nitrogen/creatinine ratio (BUN/Cr) 21...
