The ingestion of cell batteries can cause serious complications (fistula, perforation or stenosis) at the esophageal level. The damage starts soon after ingestion (approximately 2 hours) and is directly related to the amount of time the battery is lodged in said location, the amount of electrical charge remaining in the battery, and the size of the battery itself. Injury is produced by the combination of electrochemical and chemical mechanisms and pressure necrosis. The ingestion of multiple cells and a size > = 20 mm are related with more severe and clinically significant outcomes...

Ovarian vein thrombosis (OVT) is a rare condition most often seen in the immediate post-partum period. We report a 40-year-old woman with no significant past medical or surgical history who presented to the emergency room for acute right lower quadrant pain of one day duration. A computed tomography (CT) scan showed a normal appendix but a new finding of right ovarian venous thrombosis. To date, only nine cases of idiopathic OVT have been reported. In this case report, we report a summary of these cases and review of literature regarding management of OVT...

Emerging for future spintronic/electronic applications, magnetic semiconductors have stimulated intense interest due to their promises for new functionalities and device concepts. So far, the so-called diluted magnetic semiconductors attract many attentions, yet it remains challenging to increase their Curie temperatures above room temperature, particularly those based on III-V semiconductors. In contrast to the concept of doping magnetic elements into conventional semiconductors to make diluted magnetic semiconductors, here we propose to oxidize originally ferromagnetic metals/alloys to form new species of magnetic semiconductors...

Fluorescence imaging in the second near-infrared window (NIR-II, 1000-1400 nm) is attracting extensive attention. Mn(6+) doped BaSO4 with broadband emission from 900 nm to 1400 nm is emerging as a new class of NIR phosphor for fluorescence imaging. Manganese has diverse valence states, thus it is difficult to prevent valence change of Mn(6+) during traditional synthesis process. In this work, BaSO4:Mn(6+) nanoparticles with uniform size and morphology were first successfully prepared through a fast liquid-solid solution route at room temperature...

With the number of stem cell-based therapies emerging on the increase, the need for novel and efficient delivery technologies to enable therapies to remain in damaged tissue and exert their therapeutic benefit for extended periods, has become a key requirement for their translation. Hydrogels, and in particular, thermoresponsive hydrogels, have the potential to act as such delivery systems. Thermoresponsive hydrogels, which are polymer solutions that transform into a gel upon a temperature increase, have a number of applications in the biomedical field due to their tendency to maintain a liquid state at room temperature, thereby enabling minimally invasive administration and a subsequent ability to form a robust gel upon heating to physiological temperature...

PURPOSE: Early diagnosis of systemic inflammatory response syndrome is fundamentally important for an effective and a goal-directed therapy. Various inflammation biomarkers have been used in clinical and experimental practice. However, a definitive diagnostic tool for an early detection of systemic inflammation remains to be identified. Acetylcholine (Ach) has been shown to play an important role in the inflammatory response. Serum cholinesterase (butyrylcholinesterase [BChE]) is the major Ach hydrolyzing enzyme in blood...

A 19-year-old male came to the Emergency Room of our hospital due to an episode of dystonic movements and disorientation 4 days after consuming methamphetamine, which evolved to a catatonic frank syndrome and eventually to status epilepticus. Definitive diagnosis was anti-NMDA receptor encephalitis, an acute inflammation of the limbic area of autoimmune origin in which early diagnosis and treatment are key elements for the final outcome. In this case, initial normal tests and previous methamphetamine poisoning delayed diagnosis, because inhaled-methamphetamine poisoning causes similar clinical symptoms to anti-NMDA receptor encephalitis...

BACKGROUND: Medication errors represent a noteworthy source of harm to patients. In recent years, several systematic reviews have assessed the frequency and causes of these events, as well as other factors such as commonly associated drugs, their incidence in different specialties, and their consequences to patients. Despite this past literature, there remains a need to study discrepancies between these reviews and establish the current state of the evidence. The planned review will bring together, compare, and contract existing evidence related to the occurrence of medication errors in acute and continuing/long-term care settings...

The goal of the present study was to understand how current feminist multicultural supervisors understand and implement their feminist multicultural principles into clinical supervision. We addressed this aim by answering the following research question: How do self-identified feminist multicultural psychotherapy supervisors conceptualize and practice feminist supervision that is explicitly multicultural? The perspectives of 14 participant supervisors were obtained by using semistructured initial interviews, follow-up interviews, and feedback interviews and were investigated via a feminist constructivist grounded theory design and analysis...

A 59-year-old woman with a painful right knee that became locked in extension after a trivial trauma was seen at the emergency room. This was caused by unloaded hyperextension in bed. She was diagnosed with a superior dislocation of the patella. A closed reduction was performed, but a recurrent episode was seen within a week. An arthroscopy was performed, in which the causative osteophytes were removed. In the 12-month follow-up after treatment, no recurrence was seen. A superior dislocation of the patella is caused by patellofemoral osteophytes that interlock...

Seizures can be difficult to distinguish from other causes of transient cerebral hypoxia in the emergency room. We present a case of seizure activity in a woman in whom EKG led to a diagnosis of intermittent monomorphic and polymorphic ventricular tachycardia (torsades de pointes), highlighting the need for careful consideration of alternative causes of seizures, even in patients with known epilepsy.

INTRODUCTION: Statin discontinuation has been investigated in a wide range of diseases and injuries, but there is a paucity of data in the older adult population with traumatic brain injury (TBI). The purpose of this study was to re-examine the extent to which early discontinuation of pre-injury statin (PIS) therapy increases the risk of poor patient outcomes in older adult patients suffering a TBI. METHODS: This was a retrospective observational cohort study of adult trauma patients with a blunt TBI across three trauma centres over four years...

A usual source of care (USC) in primary care improves health care quality and can result in improved health. However, current research about the type of USC (place only vs. physician with a place) is insufficient as an evidence to support the value of primary care. We analyzed data from the 2012 Korea Health Panel survey of adults aged 18 years or older (n = 11,873) who reported whether having a USC or not to compare the effects by type of USC on medical care use and out-of-pocket costs. Descriptive analysis showed significant differences in the distributions of sociodemographic and health status factors except frequency of outpatient visit by type of USC...
