Trioxane is a stable cyclic trimer of formaldehyde. It is an active ingredient in fuel bars for heating prepackaged foods by military and outdoorspeople. Trioxane depolymerizes to formaldehyde in an acidic environment and is further oxidized to formic acid, which causes neurologic and ocular damage. Because it is solid at room temperature, trioxane is a greater potential hazard to children than aqueous formaldehyde. Little information is available regarding the management of ingestion of solid, compressed fuel bars. We present a case of a 19-mo-old male child who ingested an unknown amount of a trioxane fuel bar, with fortunately limited consequences.Upper extremity injuries are common among the growing population of climbers. Although conditions affecting musculoskeletal structures are the most common causes of symptoms, a comprehensive differential diagnosis is necessary to avoid the misdiagnosis of high-morbidity conditions in this patient population. We present a case of a climber with acute edema, erythema, and pain of the entire right upper extremity. After confirmation of an upper extremity deep vein thrombosis by ultrasound, and in the absence of secondary causes for his thrombotic process, he was diagnosed with effort thrombosis. The patient was treated acutely with anticoagulation, catheter thrombectomy, direct thrombolysis, and balloon angioplasty followed by surgical decompression of the subclavian vein. Owing to the importance of early diagnosis and initiation of treatment, it is critical to keep disorders affecting the upper thoracic vascular structures in consideration.The term "definitive therapy" for localized prostate cancer is a misnomer. Patients may be confused as to why "definitive therapy" sometimes requires further treatment after failure. This term should be replaced with "primary therapy".

The aim of this study was to evaluate the prevalence of CYP2 C9 polymorphism among healthy controls and patients with oral squamous cell carcinoma (OSCC) and to analyze the risk of disease development. We also investigated the interaction between CYP2 C9 wild type and the polymorphic variants with benzo[a]pyrene by using molecular docking analysis.

The study included 46 patients with OSCC and 46 controls. Amplification of the genomic DNA was done by using allele-specific polymerase chain reaction and then analyzed by using agarose gel electrophoresis. Molecular docking was then carried out to determine the interaction of CYP2 C9*1, CYP2 C9*2, and CYP2 C9*3 with benzo[a]pyrene.

In the OSCC group, CYP2 C9*2 and CYP2 C9*3 polymorphisms were 17.4% and 15.2%, respectively, and in the control group, they were 8.7% and 6.5%, respectively. The OSCC group showed a statistically significant (P=.043) increase in the prevalence of CYP2 C9 polymorphic variants compared with the control group. The docking analysis showed benzo[a]pyrene to bind specifically to the altered single nucleotide catalytic site in the polymorphic CYP2 C9*3 enzyme.

This study demonstrates that functionally important CYP2 C9 polymorphism exists among patients with OSCC, with a modest increase in the risk of disease development in those individuals who acquire these poor metabolizing variants. The modified docking of CYP2 C9*3 with benzo[a]pyrene signifies altered metabolism in vivo.

This in vitro study aimed to investigate leakage of mercury from amalgam restorations after cone beam computed tomography (CBCT) and magnetic resonance imaging (MRI) examinations.

In total, 238 amalgam disks were prepared and placed in saline solution. The samples were allocated randomly to 7 groups, with 34 samples in each group. CBCT imaging was performed for 4 groups with different imaging parameters (narrow/wide field of view [FOV]; standard/high-resolution). MRI procedures were performed with 3.0-T and 1.5-T magnetic field strengths. No imaging was performed for the samples in the control group. learn more The amalgam samples were removed from the tubes 24 hours after imaging and submitted for plasma mass spectrometry analysis. Kruskal-Wallis and Dunn's tests were performed to compare data. A P value less than .05 was accepted as statistically significant.

The highest mean mercury value was found in the 3.0-T MRI group, whereas the lowest mean value was found in the narrow FOV, standard-resolution CBCT group. There were no significant differences between the control group and the experimental groups (P ≥ .338) or between the experimental groups (P > .05).

CBCT and MRI procedures similar to those used in patient care caused no significantly different mercury release compared with nonexposed samples.

The ADVANCE III trial showed that a delayed-detection strategy reduces implantable cardioverter-defibrillator (ICD) therapies. Here, we describe the adherence to and predictors of ADVANCE adoption and compare ICD therapy rates between patients with and without ADVANCE programming.

This observational retrospective study analyzed patients implanted with Medtronic ICDs included from 2005 to 2016 in a Spanish national multicenter registry (UMBRELLA database; ClinicalTrials.gov, NCT01561144). Changes in ADVANCE programming adoption were described in relation to a) publication of the ADVANCE trial, b) implementation of an "ADVANCE awareness" campaign, and c) publication of an expert consensus statement. Multivariate logistic regression identified predictors of adoption. Therapy incidence rates were compared between groups by estimating the adjusted incidence rate ratio (aIRR) using negative binomial regression.

A total of 3528 patients were included. An ADVANCE strategy was used in 20% overall and in 44% at tence-driven selection of nominal ICD settings. ADVANCE programming is associated with reduced therapy rates in real-world ICD recipients.
