1/45. drowning due to cyclobenzaprine and ethanol.The deceased was a 35 year old female who was found by her husband in the bathtub with her head and face submerged in the water. autopsy findings were unremarkable. Toxicological analysis revealed the presence of ethanol (215 mg/dL) and cyclobenzaprine (1.786 mg/l) in the blood. This high concentration of cyclobenzaprine (Flexeril) in combination with alcohol proved to be fatal.- - - - - - - - - - ranking = 1keywords = water (Clic here for more details about this article) |
2/45. Hydrocution in a case of Coxsackie virus infection.An apparently healthy 7-year-old boy attempted to demonstrate his ability to dive into a whirlpool but was retrieved from the water in a state of unconsciousness after several minutes. resuscitation was unsuccessful. No characteristic signs of drowning were found at the autopsy but examination of the lymph nodes and the cardiac muscle indicated a pre-existent infection. The histological examination revealed a slight degree of predominantly lymphocytic infiltration of the cardiac muscle. IgM antibodies against Coxsackie virus were detected in the serum sample by means of ELISA. The reverse transcriptase polymerase chain reaction (RT-PCR) performed on an extract of formalin-fixed, paraffin-embedded cardiac muscle tissue revealed a dna sequence specific for Coxsackie B3 virus. Therefore, cardiac failure was due to a myocardial virus infection and the additional strain caused by diving. This case report emphasizes the importance of modern molecular biological methods in cases of sudden death including death by hydrocution.- - - - - - - - - - ranking = 1keywords = water (Clic here for more details about this article) |
3/45. Limbs found in water: investigation using anthropological analysis and the diatom test.We report the investigation, using a multi-disciplinary approach, of five cases of dismembered limbs which were recovered from Lake ontario, Lake Erie and the Niagara River, and examined at the Office of the Chief Coroner for ontario. In all cases, postmortem examination revealed that the limbs had been disarticulated in the postmortem period, by non-human taphonomic processes. In addition to routine gross examination, the femur and/or tibia were assessed using anthropological methods to give estimates of the sex, age, race and stature of the individual. The anthropologic data facilitated the identification of one of the cases. In all cases, nitric acid extracts of the femoral bone marrow were prepared and examined for the presence of diatoms. In all instances, diatom frustules were recovered from marrow extracts, indicating that drowning was the cause of death or at least a significant contributing factor in the cause of death. The use of the diatom test was helpful in excluding the possibility that the limbs were dismembered from individuals who had died by means other than drowning, and had been subsequently 'dumped' into water. The application of anthropological methods and the diatom test for drowning may significantly enhance the medico-legal investigation of body parts recovered from water, and we present an overview of useful techniques here. Anthropological data may facilitate identification, and the diatom test may establish a cause of death.- - - - - - - - - - ranking = 6keywords = water (Clic here for more details about this article) |
4/45. Diatom numbers around the continental shelf break.Diatom concentrations in seawater were examined monthly at four aquatic areas. Diatom concentrations inside a bay showed a monthly variation, but these were detectable. On the other hand, in the open sea around the continental shelf break, there were few diatoms in any season. When a person drowns in the open sea, the diatom test cannot be expected to function reliably.- - - - - - - - - - ranking = 1keywords = water (Clic here for more details about this article) |
5/45. Pulmonary interstitial fibrosis following near-drowning and exposure to short-term high oxygen concentrations.Following near-drowning in fresh water, a 19-year-old man experienced severe adult respiratory distress syndrome, necessitating ventilatory support with positive end-expiratory pressure and high oxygen concentrations. Post-extubation, his course was highlighted by persistent hypoxemia and interrupted by a lung abscess which responded promptly to antibiotics. Pulmonary function tests were consistent with severe restrictive disease and chest radiograph revealed persistent bilateral alveolar and interstitial infiltrates. An open lung biopsy on the 26th hospital day showed interstitial fibrosis. Over the ensuing two months, the chest radiograph and pulmonary function tests returned towards normal. We attribute the pulmonary fibrosis to incomplete resolution of the alveolar interstitial pathology secondary to the near-drowning and exposure to high oxygen mixtures.- - - - - - - - - - ranking = 1keywords = water (Clic here for more details about this article) |
6/45. Respiratory colonization with pseudomonas putrefaciens after near-drowning in salt water.pseudomonas putrefaciens, a marine organism infrequently found in human culture material, was repeatedly isolated from the sputum of a patient with pneumonia during a three-week period following a salt-water drowning accident. Similar organisms were found in the water at the site of the accident in boston, and at ocean bathing beaches on nearby Martha's Vineyard.- - - - - - - - - - ranking = 6keywords = water (Clic here for more details about this article) |
7/45. drowning as a cause of death in angelman syndrome.angelman syndrome is characterized by mental retardation, seizures, ataxia, inappropriate laughter, lack of speech, a particular facial appearance, and generally a chromosome 15q11-q13 deletion. Recently, a fascination with water and water-related activities has been reported in individuals with the syndrome. We report on a 9.6-year-old male previously diagnosed with angelman syndrome who died unexpectedly by drowning in a shallow backyard wading pool. This case further illustrates the fascination with water by individuals with angelman syndrome and highlights that this fascination may lead to death. We wish to alert careproviders that this fascination with water and water-related activities may contribute to death and that these individuals should be closely supervised when in the presence of water.- - - - - - - - - - ranking = 6keywords = water (Clic here for more details about this article) |
8/45. Neurodevelopmental outcome for extended cold water drowning: a longitudinal case study.There is little longitudinal data examining outcome of pediatric near-drowning. Most literature tracks status 5 years or less post insult, focusing primarily on gross neurologic status as opposed to more subtle neurocognitive deficits. The present case tracks the neuropsychological profile of a child who was submerged for 66 min, the longest time documented. Acute medical support was aggressive, and recovery was dramatic, being featured in multiple media reports. Although an article published 6 years after the near-drowning described the child as "recovering completely," the longitudinal profile indicates a pronounced pattern of broad cognitive difficulties, particularly notable for global memory impairment. Neuropsychological test results were significant despite the fact that the patient's recent MRI and MEG were within normal limits. This case demonstrates the need for long-term neuropsychological follow-up of pediatric patients with histories of neurologic injury, as gross neurological examination and MRI and MEG scans may not reveal underlying brain dysfunction.- - - - - - - - - - ranking = 4keywords = water (Clic here for more details about this article) |
9/45. Did he drown or was he murdered?An unemployed, 60-year-old Singaporean gentleman died during a brief overseas trip to another South-East Asian country. He had, presumably, drowned in the bathtub of his hotel room, which he shared with his then 44-year-old companion, who was supposedly his nephew. The relevant public health and medico-legal authorities of the host country conducted an external examination of the body at the scene, whereupon they agreed with the police that his death was probably due to accidental drowning following an episode of syncope. It would appear that this verdict was based almost entirely on circumstantial and hearsay evidence. No autopsy was performed. In its place, considerable reliance was placed on the observation that abdominal compression resulted in the outflow of a small amount of water from the mouth, as being proof of drowning. A few days later, the body was cremated in the host country and the remains (ashes) were subsequently repatriated to singapore. It later transpired that, shortly before they embarked on the ill-fated trip, the deceased's 'nephew' had purchased, on the former's behalf, travel insurance policies (covering accidental injury and death) amounting to a total of S$800,000 from five different insurance companies, as well as a separate life policy for a further S$100,000, most of which had been issued within the fortnight prior to their departure. Interestingly, the beneficiary (later the plaintiff in the ensuing civil trial some three years later) of all of these policies, was the ex-wife of the deceased's 'nephew', with whom he had, in fact, continued to live although they were officially divorced several years ago. Whilst the claim against the life policy had been settled, the first five insurers declined to issue payment on grounds of suspicion that the deceased had been the victim of a homicide, planned or executed by the 'nephew', wherein the beneficiary was a conspirator of sorts. The author was approached by defence counsel (representing the various insurers), for assistance in this matter. It was felt that a proper forensic review was seriously hampered by the lack of a full autopsy which would have been indispensable in ascertaining the actual cause of death and in eliminating other possibilities, apart from drowning, such as death from natural causes, other forms of injury, poisoning, or homicide. It was also emphasized that the mere presence of ingested water is not diagnostic of drowning. Eventually, after a protracted but unsuccessful attempt at mediation (in the course of which, the plaintiff rejected the offer of a reduced, although apparently sizable quantum), the matter came before the High Court, which found in favour of the defendants. It appeared that the judge was more than convinced that the deceased was indeed the victim of a homicide of which the plaintiff was a conspirator and her ex-husband, the perpetrator, as even a cursory perusal of the written judgement would indicate. Accordingly, the court ruled that the plaintiff (in her capacity as both the beneficiary of the insurance policies and executor of the estate) and her ex-husband had, effectively, deprived the insurers of their contractual right (as stipulated in the insurance policies) to have an autopsy conducted on the body of the deceased and they were, therefore, entitled to deny liability. This case illustrates the difficulties inherent in conducting an independent review of a putative instance of drowning, where convincing and reliable forensic evidence and documentation are largely wanting; this being compounded by its occurrence in a foreign jurisdiction whose medico-legal practices differ substantially from that to which one is accustomed. It may even be said that the corpus delecti was destroyed, in this instance, by cremation. It is also unusual in that a de-facto finding of murder was made in a civil court (whose standard of proof is that of a balance of probabilities) and that this had, subsequently, spurred the police to undertake a criminal investigation for conspiracy to murder. In the event, the civil appeal was dismissed by the Court of Appeal, but no charge was laid against any of the suspects for want of sufficient forensic or investigative evidence of a criminal offence having been committed.- - - - - - - - - - ranking = 2keywords = water (Clic here for more details about this article) |
10/45. Into hot water head first: distribution of intentional and unintentional immersion burns.INTRODUCTION: Experience with several, previously unreported, intentional face-first immersion burns led us to evaluate the distribution of inflicted and unintentional immersion scald burns in a hospital series. SETTING: (1) Authors' clinical and legal practices; (2) Burn center at regional Level 1 trauma hospital. SUBJECTS:: (1) Case series of face-first, inflicted immersion burn victims; (2) Consecutive hospitalized scald burn victims younger than 5 years old, 1/3/1996 to 3/25/2000. methods: (1) Individual case reports; (2) Retrospective records review. Simple descriptive statistics, Fisher Exact test and t test. RESULTS: (1) Six cases of inflicted head and neck immersion injury are described. Four were tap water and 2 food/drink scalds. (2) 22/195 hospitalized victims had sustained immersion burns, 13 from tap water and 9 from other fluids. Six (46%) tap water immersions and no (0%) other immersions had inflicted injuries (P = 0.05). Two of the tap water immersions and one other source immersion included burning of the head and neck. Of these, one tap water immersion, but no other immersion, was inflicted. In no patients were head and neck injuries the sole or predominant site of scalding. In all, 9 children sustained inflicted scalds. Bilateral lower extremity tap water immersion scalds occurred in 100% (6/6) of abusive and 29% (2/7) of unintentional injuries (P = 0.02). Buttock and perineal injuries occurred in 67% (4/6) inflicted versus 29% (2/7) unintentional tap water immersion scalds (P = 0.28). Other fluids caused bilateral lower extremity immersion burns in 3/9 (33 %) unintentionally injured patients, but no abused children (NS). CONCLUSIONS: Craniofacial immersion injury, although seen by the authors in legal cases, is infrequent. It was present incidentally in one inflicted tap water burn in the consecutive hospital series. This series affirms the predominance of bilateral lower extremity burns in inflicted tap water immersions. Buttock/perineal immersions were more common with abuse than with unintentional injury.- - - - - - - - - - ranking = 13keywords = water (Clic here for more details about this article) |
