Amanita Mushroom Toxin Poisoning in Los Angeles County.

Mushroom (amatoxin) poisoning from ingestion is a rare but life-threatening medical emergency characterized by gastrointestinal symptoms before progression to multisystem organ failure in severe cases. Many therapies of amatoxin intoxication have been described, including supportive care, medical therapies, detoxification strategies, and liver transplant. The evidence supporting these therapies remains limited due to the rarity of amatoxin poisoning and challenge of a timely diagnosis.

Outcomes Following Percutaneous Cholecystostomy Tube Placement for Acalculous Versus Calculous Cholecystitis.

Background: Acute acalculous cholecystitis (AAC) is often diagnosed in critically ill patients. Percutaneous cholecystostomy tube (PCT) placement facilitates less invasive gallbladder decompression in patients who are poor surgical candidates. Specific guidelines for optimal management of AAC patients following PCT placement remain to be defined.

Percutaneous Cholecystostomy Tube for Acute Cholecystitis: Quantifying Outcomes and Prognosis.

Background: Percutaneous cholecystostomy tubes (PCT) are utilized in the management of acute cholecystitis in patients deemed unsuitable for surgery. However, the drive for these decisions and the outcomes remain understudied. We sought to characterize the practices and utilization of PCT and evaluate associated outcomes at an urban medical center.

Comparing clinical outcomes of image-guided percutaneous transperitoneal and transhepatic cholecystostomy for acute cholecystitis.

Background: Percutaneous cholecystostomy is performed by interventional radiologists for patients with calculous/acalculous cholecystitis who are poor candidates for cholecystectomy. Two anatomical approaches are widely utilized: transperitoneal and transhepatic.

Purpose: To compare the clinical outcomes of transperitoneal and transhepatic approaches to cholecystostomy catheter placement.

Effect of scheduling inferior vena cava filter removal during the placement encounter on filter removal rate.

Objective: In the present study, we sought to determine whether early pre-emptive scheduling of inferior vena cava filter (IVCF) removal during the preoperative IVCF placement visit would affect the IVCF removal rate.

Methods: All electronically documented IVCF placements at a single institution were reviewed from April 2015 to July 2019. The baseline characteristics included age, the clinical indications for IVCF placement, inpatient/outpatient status, and type of IVCF placed.

Median Arcuate Ligament Syndrome and Its Associated Conditions.

The risk factors and associated conditions of median arcuate ligament syndrome (MALS) have not been well characterized in the literature. In this study, we aim to investigate the presentation and outcomes of MALS patients with an emphasis on the prevalence of other uncommon disorders. To this end, data of patients with MALS who underwent surgery between 2013 and 2018 were collected and compiled into a retrospective database and analyzed.

Complications and retrieval characteristics of Celect Platinum inferior vena cava filters.

Background: The purpose of this study was to retrospectively assess the retrieval characteristics and rate of filter-related complications associated with use of the Celect Platinum (Cook Medical, Bloomington, Ind) inferior vena cava filter (IVCF).

Methods: A single-center, retrospective review was conducted to identify patients who received a Celect Platinum IVCF between June 2013 and February 2016. The patients' charts and imaging records (computed tomography [CT] and cavography) associated with filter placement, follow-up, and filter retrieval procedures were assessed for attempted and successful retrieval rates and filter-related complications.

Health Worker Focused Distributed Simulation for Improving Capability of Health Systems in Liberia.

Introduction: The main goal of this study was to produce an adaptable learning platform using virtual learning and distributed simulation, which can be used to train health care workers, across a wide geographical area, key safety messages regarding infection prevention control (IPC).

Methods: A situationally responsive agile methodology, Scrum, was used to develop a distributed simulation module using short 1-week iterations and continuous synchronous plus asynchronous communication including end users and IPC experts. The module contained content related to standard IPC precautions (including handwashing techniques) and was structured into 3 distinct sections related to donning, doffing, and hazard perception training.

Add-on histamine receptor-3 antagonist for allergic rhinitis: a double blind randomized crossover trial using the environmental exposure unit.

Background: Oral antihistamines that target the histamine receptor-1, such as fexofenadine, offer suboptimal relief of allergic rhinitis-associated nasal congestion. Combinations with oral sympathomimetics, such as pseudoephedrine, relieve congestion but produce side effects. Previous animal and human studies with histamine receptor-3 antagonists, such as PF-03654764, demonstrate promise.

Efficacy and safety of the oral p38 inhibitor PH-797804 in chronic obstructive pulmonary disease: a randomised clinical trial.

Rationale: Chronic obstructive pulmonary disease (COPD) is a common lung disease leading to progressive decline in lung function. Inhibition of release of inflammatory mediators by p38 inhibitors may be a useful treatment for chronic inflammation of the airways thought to underlie the pathogenesis of the disease.

Objectives: To evaluate the efficacy and safety of PH-797804, a potent and selective p38 inhibitor, in adults with moderate to severe COPD (Global Initiative for Chronic Obstructive Lung Disease stage II/III).

The effects of an H3 receptor antagonist (PF-03654746) with fexofenadine on reducing allergic rhinitis symptoms.

Background: Nasal H(3) receptors might have a role in mediating the effects of histamine in patients with allergic rhinitis.

Objective: This study explored the effect of the potent oral H(3) receptor antagonist PF-03654746 in combination with an oral H(1) receptor antagonist on the objective (acoustic rhinometry) and subjective (symptoms) responses to nasal allergen challenge.

Methods: Twenty patients with out-of-season allergic rhinitis displaying a 30% or greater decrease in minimum nasal cross-sectional area (A(min)) after bolus (ragweed) complete nasal allergen challenge at screening were studied by using a randomized, double-blind, single-dose, 4-way crossover design.

Superior sensitivity of angiographic detection of arteriovenous fistula after biopsy in a renal allograft with CO2 compared with iodinated contrast medium.

Arteriovenous (AV) fistulas are potential complications of renal transplant biopsy procedures. In the setting of renal transplant failure, angiography with CO2 as a contrast agent is a useful adjunct to angiography with conventional contrast medium in the diagnosis and treatment of such fistulas with minimal nephrotoxicity. The present report describes a case of a renal transplant AV fistula seen after biopsy that could be detected angiographically only with CO2 contrast medium.
