Near drowning in frigid water: A case study of a 31-year-old woman

AbstractA 31-yr-old woman demonstrated intact neuropsychological functioning after being submerged for at least 30 minutes in icy cold water. Following submersion, the patient received CPR for approximately 1 hr. Eight hours after submersion, the patient's temperature was 31°C (87°F). She remained nonresponsive for 2 days after the accident. Extensive neuropsychological testing was completed 3 mo after the accident with no objective or subjective deficits evidenced. This case of hypothermically mediated neuroprotection from anoxia in an adult supports the need for further research on the putative neurophysiological mechanisms invoked and the potential for application of clinically induced hypothermia in the acute management of other types of cerebral insults.

Objectives: Although clear advances have been achieved in the study of early-onset schizophrenia (EOS), little is known to date about premorbid and prodromal neuropsychological functioning in EOS. Method: Here, we report on a case of an adolescent male with EOS who underwent neuropsychological testing before and after illness onset. Results: Marked cognitive deficits in the domains of attention, set-shifting, and verbal memory were present both pre-onset and during the course of schizophrenia, though only deficits in verbal memory persisted after illness-onset and antipsychotic treatment. Conclusion: The findings of this case study suggest that impairments in the verbal memory domain are particularly prominent symptoms of cognitive impairment in prodromal EOS and persist in the course of the disorder, which further demonstrates the difficult clinical situation of adequate schooling opportunities for adolescent patients with EOS.

Modified Wood

Abstract Chemical modification is increasing the durability of wood against biological deterioration. Usually, the effect of a new treatment on the durability of wood is screened in laboratory decay tests, where durability classes are assigned on the basis of the mass loss (ML) caused by degrading fungi. The aim of this study was to demonstrate how non-fixated chemicals in modified wood may affect fungal ML measurements and corresponding durability classification when wood samples are incubated under humid conditions for long periods. Wood blocks were treated with solutions of 1,3-dimethylol-4,5-dihydroxyethyleneurea (DMDHEU), methylated DMDHEU (mDMDHEU) and 1,3-dimethyl-4,5-dihydroxyethyleneurea (DMeDHEU) and subjected to consecutive cold-water leaching cycles. Significant amounts of non-fixated chemicals were removed from the wood by three leaching cycles and might lead to ML mistaken as response of fungal decay. Consequently, the treated material was assigned erroneously by up to four durability classes (DC) worse than material which did not include leachable, non-fixated chemicals. Thus, for a reliable durability classification of chemically modified wood, prolonged leaching procedures are recommended to assure that the measured ML is entirely attributed to fungal decay.

Near Drowning

There have been 81 patients brought to Treliske Hospital, Truro, UK in the last 6 years, having been rescued from near-drowning. Only 5 have been declared dead on arrival and not treated. We consider that hypothermia is a major factor in patients who have apparently drowned, particularly when it has been known that they were strong swimmers. In 1980, 45% of all drownings had rectal temperatures less than 35°C. The sea temperature around our shores varies between 5°C in January and 15.5°C in September. Hypothermia causes little problem until a central temperature of 35°C or less is reached. Between 35°C and approximately 32°C there is disorientation and incoordination, which may make swimming difficult to maintain efficiently. Below 32°C there is loss of consciousness; when this occurs, the victim's head drops below the water level and drowning occurs just as quickly as in a victim who is unconscious on entering the water.
