A growing body of evidence has confirmed that, after severe brain injury in adults, motoric and task-dependent factors that are essential for reliable communication, frequently interfere with an accurate assessment of cognitive status. In the current study, resting state functional magnetic resonance imaging (fMRI) in children who have sustained an anoxic brain injury following a near drowning incident suggests a similar pattern; preserved cognition amidst severe motoric impairment that effectively precludes accurate clinical diagnosis at the bedside...

The continental shelves are the most biologically dynamic regions of the ocean, and they are extensive worldwide, especially in the western North Pacific. Their area has varied dramatically over the glacial/interglacial cycles of the last million years, but the effects of this variation on ocean biological and chemical processes remain poorly understood. Conversion of nitrate to N2 by denitrification in sediments accounts for half or more of the removal of biologically available nitrogen ("fixed N") from the ocean...

A 1-year-10-month-old boy was admitted to our pediatric intensive care unit due to near drowning with pulmonary edema. A conventional ventilator with 100% oxygen supplementation was used initially, but was shifted to high frequency oscillatory ventilation as his oxygen saturation was around 84-88%. Therapeutic hypothermia was applied due to hypoxic ischemic encephalopathy with severe acidosis. His respiratory condition improved and he was extubated successfully on the 6(th) hospital day. The patient had no obvious neurological defects and he was discharged in a stable condition after 17 days of hospitalization...

BACKGROUND: In 2002, the World Congress on Drowning developed a uniform definition for drowning. The aim of this study is to determine the prevalence of "non-uniform drowning terminology" (NUDT) and "non-uniform drowning definitions" (NUDD) in peer-reviewed scientific literature from 2010 to 2016, and compare these findings with those from our unpublished study performing a similar analysis on literature from 2003 to 2010. METHODS: A systematic review was performed using drowning-specific search terms in Pubmed and Web of Science...

Scedosporium apiospermum is known to be a fungal pathogen affecting immunocompromised as well as non-immunodeficient patients. Although this fungus is found rarely, an infection can lead to severe and even fatal disease. Here, we describe the case of a 41-year-old female who developed multiple Scedosporium apiospermum brain abscesses after near-drowning with aspiration of contaminated mud and water. She showed various neurological symptoms. The patient recovered after removal of abscesses in combination with long-term antifungal treatment...

Drowning is the major cause of death in self-contained underwater breathing apparatus (SCUBA) diving. This study proposes an embedded system with a live and light-weight algorithm which detects the breathing of divers through the analysis of the intermediate pressure (IP) signal of the SCUBA regulator. A system composed mainly of two pressure sensors and a low-power microcontroller was designed and programmed to record the pressure sensors signals and provide alarms in absence of breathing. An algorithm was developed to analyze the signals and identify inhalation events of the diver...

Drowning is a crucial public safety problem and is the third leading cause of accidental fatality, claiming ~372,000 lives annually, worldwide. In near-drowning patients, acute lung injury (ALI) or acute respiratory distress syndrome (ARDS) is one of the most common complications. Approximately 1/3 of near-drowning patients fulfill the criteria for ALI or ARDS. In the present article, the current literature of near-drowning, pathophysiologic changes and the molecular mechanisms of seawater-drowning-induced ALI and ARDS was reviewed...

Introduction Drowning with submersion over 10 minutes is associated with a high mortality. Here, we present a case, in which a good neurological outcome was achieved after interdisciplinary, intensive care therapy despite submersion of 20 minutes followed by 16 hours of hypoxia. History A 19 year old man drowned in fresh-water. After 20 minutes submersion he was localized and salvaged from 8 meters depth and primarily resuscitated successfully after 10 minutes. Within the next hour, there condition worsened by respiratory deterioration due to a massive capillary leak syndrome in addition to a disseminated intravascular coagulation...

BACKGROUND: Plague, a Yersinia pestis infection, is a fatal disease with tremendous transmission capacity. However, the mechanism of how the pathogen stays in a reservoir, circulates and then re-emerges is an enigma. METHODOLOGY/PRINCIPAL FINDINGS: We studied a plague outbreak caused by the construction of a large reservoir in southwest China followed 16-years' surveillance. CONCLUSIONS/SIGNIFICANCE: The results show the prevalence of plague within the natural plague focus is closely related to the stability of local ecology...

Terrestrial insects in water can often delay or escape drowning by floating and swimming. However, we observed that flooding of pitfall traps baited with rotting carrion results in high overnight mortality of captured beetles and reasoned that this risk may be enhanced by microbial respiration. By assessing carrion beetle (Coleoptera: Silphidae) response to flooding, tolerance to immersion, and swimming behavior, we offer insights to this cause of death and beetle behavioral physiology. Response of buried Nicrophorus orbicollis Say to soil flooding resulted in beetles moving to the soil surface...

Noncardiogenic pulmonary edema is an important cause of respiratory disease in dogs and cats but few reports describe its radiographic appearance. The purpose of this retrospective case series study was to describe radiographic findings in a large cohort of dogs and cats with presumed noncardiogenic pulmonary edema and to test associations among radiographic findings versus cause of edema. Medical records were retrieved for dogs and cats with presumed noncardiogenic edema based on history, radiographic findings, and outcome...

Verdict on tracing exact place of drowning is a part of medico-legal investigation. This question often stands when circumstances remain unclear about true drowning place. Usually, when a dead body rises from the bottom of drowning site, it will appear near to the point where it had actually disappeared but rapid current may carry a body to real distance from the exact place of death before any major obstruction. Forensic methodology has suggested qualitative as well as quantitative comparison of diatoms recovered in dead body and reference water samples to corroborate drowning as cause of death and locating precise place of drowning...

Cardiac magnetic resonance imaging (cMRI) is a well-established noninvasive imaging modality in clinical cardiology. Its ability to provide tissue characterization make it well suited for the study of patients with cardiac diseases. We describe a multi-modality imaging evaluation of a 45-year-old man who experienced a near drowning event during swimming. We underline the unique capability of tissue characterization provided by cMRI, which allowed detection of subtle, clinically unrecognizable myocardial damage for understanding the causes of sudden cardiac arrest and also showed the small damages caused by cardiopulmonary resuscitation...
