Issue Addressed: There is a scarcity of research into portable pool drowning and its prevention. This total population study examines fatal drowning among children under five in portable pools in Australia., Methods: All child drowning deaths in portable pools for the period 1 July 2002 to 30 June 2018 were identified. A portable pool was defined as any structure used for swimming and wading which, when emptied, can be moved., Results: Twenty-three children (aged 0-17 years) drowned in portable pools. The drowning rate for children less than 5 years of age was 0.09 per 100 000 population. The peak age of death was 12-23 months (RR = 2.99; CI: 1.09-8.23), with the majority (n = 20 deaths) aged 16-31 months. Ninety per cent followed a fall into water. None were supervised. Children commonly resided in areas classified as socially and economically disadvantaged (85%; n = 17). Drowning rates in very remote areas were 15 times greater (RR = 15.41; CI: 0.03-7579.65) than city children. Eleven (55%) drowning deaths occurred in pools with a depth >300 mm, of which 10 (91%) were known to be unfenced., Conclusions: Social determinants impact child drowning in portables pools, which can occur quickly and in just 150 mm of water. Active supervision and a regulation-compliant barrier are effective prevention stratagems, factors which were absent from the deaths in this study. SO WHAT?: Portable pool drowning disproportionately impacts those aged 16-31 months who reside in very remote areas and areas classified as having high socio-economic disadvantage. Education for these groups on fencing and supervision of children must be provided., (© 2019 Australian Health Promotion Association.)

Aim: To establish the prevalence of unintentional fatal drowning in baths involving children <18 years in Australia and to identify causal factors to underpin prevention., Methods: We report a total population study of all childhood (0-17 years) unintentional drowning fatalities in baths (bathtubs, spa baths and showers) in Australia between 1 July 2002 and 30 June 2014. Demographic, forensic and aetiological data (including co-bathing, use of bath aids, supervision and enactment of cardiopulmonary resuscitation) were documented for each victim., Results: Seventy-eight children were identified; two thirds (66.7%) were under 2 years old, of which 43.6% were aged less than 1 year (1.0/100 000/annum) and 23.1% 1-2 years (0.27/100 000/annum). Nine older children (10-17 years) also drowned. Common causes included: infants and children unable to hold their head out of water while unsupervised and associated pre-existing medical conditions, including epilepsy. All children who drowned were left without adult supervision. No child drowned in a bath with water deeper than 40 cm (M = 19.4 cm). Custodian-reported 'time left unsupervised' ranged from 30 s to 60 min. Children with pre-existing medical conditions were, on average, older (9.9 years; confidence interval: 7.9-11.9) and left unsupervised for longer (M = 15.4 min; confidence interval: 3.8-27.1) than those without., Conclusions: On average, 6.5 children drown every year in baths in Australia. Children aged younger than 1 year are most affected, with both genders equally represented. Infants and toddlers left unsupervised, false confidence in the preventive role of bath aids, unrealistic expectations in the supervisory capabilities of co-bathing children and epilepsy remain threats to children in the bath., (© 2017 Paediatrics and Child Health Division (The Royal Australasian College of Physicians).)

Objectives: This study is an analysis of the contribution of pre-existing medical conditions to unintentional fatal child (0-14 years) drowning and a of critique prevention stratagems, with an exploration of issues of equity in recreation., Design: This study is a total population, cross-sectional audit of all demographic, forensic and on-site situational details surrounding unintentional fatal drowning of children 0-14 years in Australia for the period of 1 July 2002 to 30 June 2012. Data were sourced from the National (Australia) Coronial Information System. Age-specific disease patterns in the general population were obtained from the Australian Institute of Health and Welfare., Results: Four hundred and sixty-eight children drowned during the study period. Fifty-three (11.3%) had a pre-existing medical condition, of whom 19 suffered from epilepsy, 13 from autism and 5 with non-specific intellectual disabilities. Epilepsy is a risk factor in childhood drowning deaths, with a prevalence of 4.1% of drowning fatalities, compared with 0.7%-1.7% among the general 0-14 years population (relative risk: 2.4-5.8). Epilepsy was deemed to be contributory in 16 of 19 cases (84.2% of epilepsy cases) with a median age of 8 years. Asthma and intellectual disabilities were under-represented in the drowning cohort., Conclusion: Except for epilepsy, this research has indicated that the risks of drowning while undertaking aquatic activities are not increased in children with pre-existing medical conditions. Children with pre-existing medical conditions can enjoy aquatic activities when appropriately supervised., Competing Interests: Competing interests: None declared., (© Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2017.

The emergence of paediatrics as a specialty in Australian medicine dates from the last two decades of the 19th century. Among the pioneers of pre-Federation paediatrics, we include Dr Henry Edward Brown (1858-1931), an Irish-born physician and surgeon who became the first paediatrician to practise in the northern half of the Australian continent. In 1885, he was appointed as the medical superintendent of the Rockhampton Children's Hospital, itself a pioneer institution in the care of sick and injured children. Dr H.E. Brown also served as medical officer of health concurrently in three Queensland shires. He was a leader in the literary and sporting life of the busy port town of Rockhampton and a scholar and significant philanthropist in the domain of French literature. His life was and remains an exemplar of a class of pre-Federation paediatricians who established the ethos of clinical and societal service, which remains as a core feature of the speciality discipline of paediatrics in the 21st century., (© 2014 The Authors.

Botanical taxonomy is a repository of medical biographical information. Such botanical memorials include the names of some indigenous orchids of Australia. By searching reference texts and journals relating to Australian botany and Australian orchidology, as well as Australian and international medical and botanical biographical texts, I identified 30 orchids indigenous to Australia whose names commemorate doctors and other medical professionals. Of these, 24 have names that commemorate a total of 16 doctors who worked in Australia. The doctors and orchids I identified include: doctor-soldiers Richard Sanders Rogers (1862-1942), after whom the Rogers' Greenhood (Pterostylis rogersii) is named, and Robert Brown (1773-1858), after whom the Purple Enamel Orchid (Elythranthera brunonis) is named; navy surgeon Archibald Menzies (1754-1842), after whom the Hare Orchid (Leptoceras menziesii) is named; radiologist Hugo Flecker (1884-1957) after whom the Slender Sphinx Orchid (Cestichis fleckeri) is named; and general medical practitioner Hereward Leighton Kesteven (1881-1964), after whom the Kesteven's Orchid (Dendrobium kestevenii) is named. Biographic references in scientific names of plants comprise a select but important library of Australian medical history. Such botanical taxonomy commemorates, in an enduring manner, clinicians who have contributed to biology outside clinical practice.

Objective: To examine the frequency and causes of snorkelling-related deaths in Australia., Design, Setting and Subjects: We conducted a retrospective analysis of snorkelling-related deaths recorded in Australia from 1994 to 2006 inclusive, based on information from the Divers Alert Network Asia-Pacific database, the National Coroners Information System, coronial files from all states and territories, and annual national drowning reports., Main Outcome Measures: Number and attributed causes of snorkelling-related deaths., Results: We identified 140 snorkelling-related deaths. Forensic details were available for 130 of these. Four principal cause-of-death categories were identified: deaths from cardiac or suspected cardiac causes (60), deaths from surface drowning (largely in inexperienced snorkellers) (33), deaths from drowning after prolonged breath-hold diving (largely in experienced divers) (19), and deaths from trauma (10). Eight people died of other causes., Conclusions: In the context of the large population sampled, snorkelling-related deaths are rare. Preventive measures for such deaths could include pre-dive medical assessments for people with a history of cardiac or respiratory disease or with a family history of sudden unexpected death; improved training in how to use snorkelling equipment; better matching of skills to health, fitness and water conditions; better supervision and quality training of supervisors in rescue and resuscitation techniques; and avoidance of hyperventilation before breath-hold diving.

Sick and injured children, like combatants wounded by shot and shell in war, are disproportionately represented in the tallies of both man-made and national disasters. Paediatricians have a particularly proud heritage of military service, a nexus dating in Australia from the early 19th century. This paper traces this link between service to children in peacetime and the care of servicemen, women and children in times of war and disaster. The extraordinary record of Australian 'paediatric' doctors who also served in the Gallipoli Campaign (1915) is documented as an illustration of this duality. Paediatricians who serve in the Defence Reserves and in civilian non-government organisations which respond to disasters and civil wars have special credentials in their advocacy for the protection of children enmeshed in conflict or disaster. Such applies particularly to the banning of the recruitment and use of child soldiers; support for children caught up in refugee and illegal immigrant confrontations; and continued advocacy for greater international compliance with the Ottawa Convention to ban the use of anti-personnel landmines. Volunteering for such service must occur in cold 'down time', ensuring that paediatricians are trained in disaster and conflict response, when such challenges inevitably confront the paediatricians of the future., (© 2012 The Author.

Introduction: Non-intentional child drowning remains a leading cause of child mortality. A related and secondary syndrome is composed of those who drown in impulsive, altruistic attempts to go to the aid of a drowning child. Such 'rescuers' who attempt to save a drowning child may themselves drown, a tragic event we term the AVIR syndrome or aquatic victim-instead-of-rescuer., Methods: This study is composed of a five-year (1 July 2002 to 30 June 2007) total population Australian survey, using the National Coroners Information System to identify cases and an analysis of every immersion rescuer-victim dyad where the primary 'victim' was a child and where the 'rescuer' drowned., Results: In Australia (2002-2007), 17 rescuers drowned in 15 incidents in which the primary victim was a drowning child. In 93% of the incidents, the primary 'child-victim' survived, 82% of the victims were unfamiliar with the aquatic location (i.e. were a visitor) and 76% of the victims were a male parent, partner of first-degree relative. Alcohol was not generally involved., Conclusion: We define the AVIR syndrome as one that typically involves the following: a male, parent, partner or relative; an unfamiliar water hazard; a 'rescuer' who is a tourist; alcohol is not usually involved; and the primary victim usually survives. We posit that an increased awareness of such risks, the promotion of rudimentary rescue skills (e.g. being able to throw a lifeline) and increased advocacy for parents to learn the simple and basic life-saving skills of non-contact rescue will help reduce these drowning tragedies., (© 2010 The Authors.

Objective: To explore 5 years of drowning deaths in Australia compared with a previous Australian study a decade earlier, and to assess the feasibility of achieving a 50% reduction in unintentional drowning deaths by 2020., Design and Setting: An audit of all unintentional drowning deaths in Australia using data from the National Coroners Information System for 1 July 2002 to 30 June 2007., Main Outcome Measures: Number and rate of drowning deaths, by age, sex, location, activity, place of birth, visitor status, and involvement of alcohol or drugs., Results: There were 1452 drowning deaths during the study period (76.4% male). The age-adjusted rate per 100 000 people ranged from 1.61 in 2002-03 to 1.23 in 2006-07. Children aged 0-4 years had the highest rate (2.63 per 100 000 people), and 29% of deaths were of people aged 55 years or older. Over half of all deaths occurred in rivers (20.3%), at beaches (18.3%), or in swimming pools (13.3%). Alcohol was involved in 21.6% of all drowning deaths, although this varied by age., Conclusions: This audit suggests that a 50% reduction in drowning fatalities by 2020 may be achievable using current knowledge and preventive systems in certain types of immersions. However, further research and new initiatives will be required, particularly to prevent drowning deaths in rivers and of older people.

Ciguatera is a common form of fish poisoning, endemic in all nations of the Pacific region. Several thousand cases have been notified to Queensland authorities over a 10-year period. However, many cases remain undiagnosed and most go unreported. The public health implications include raising awareness of the condition, ensuring that ciguatera is considered in differential diagnosis and promoting better documentation and reporting.

In the aftermath of the Rwandan civil war, Australia's defence forces deployed a medical force to support the United Nations Assistance Mission. In this article, Wayne Ramsey, Commander of the Australian contingent, Lindsay R Bridgford, Officer Commanding Bravo Section, Robert J Lusby, Lt.-Colonel (Surgeon), Australian Medical Support Force Hospital, and John H Pearn, Colonel, and Director of Intensive Care in the Australian Medical Support Force Hospital, describe the Australian effort in the rebuilding of a shattered people and, in particular, of Kigali Central Hospital, the country's major medical facility.

Objectives: To define the risk of snake envenomation in herpetologists, assess factors which lead to their being bitten, assess their occupational morbidity and propose preventive stratagems., Subjects and Design: Interview of 14 of the most experienced professional herpetologists in Queensland; and questionnaire to 14 members of the Cape York Peninsula Herpetological Society, Cairns, Queensland., Results: The 28 herpetologists had sustained 119 bites by potentially dangerous species, and hundreds of clinically insignificant bites. Seventeen had been admitted to hospital. Only five had never been bitten by a medically dangerous snake and 14 had been bitten on two or more occasions. Correct first-aid techniques were applied in less than half the bites. Two had permanent morbidity--renal damage, and permanent tissue damage to the hands. Anaphylactic reactions from the repeated use of antivenom did not occur. The experienced herpetologists sustained a life-threatening bite every 10 years (median). Four herpetologists had been bitten by the western taipan (Oxyuranus microlepidotus), the world's most venomous snake., Conclusions: Herpetologists working with highly venomous snakes are at high risk. Prevention involves recognising the risk; possessing a first-aid certificate; applying standard first-aid if a bite is sustained; carrying a mobile telephone; and not working alone.

The first 2 exchange transfusions in Australia for Rhesus-induced erythroblastosis (hemolytic disease of the newborn) were conducted in the 9 mth period from December 1945 to August 1946. These pioneering endeavours in medical research were undertaken by 3 transfusionists who were, or had been, directors of the Red Cross Blood Transfusion Service in Australia. Called "substitution transfusion" or "exsanguination transfusion" they were conducted prior to the international publication of the first case series of exchange transfusions for "Rhesus Disease". The first successful exchange transfusion in Australia, and one of the first in the world, was performed by Dr George Kelsall at the King Edward Memorial Hospital for Women, in Perth. Dr Kelsall had monitored pregnancies with serum raised himself from blood from a Rhesus monkey in the Perth Zoo. The second exchange transfusion, and the first with volume-monitoring, was successfully undertaken in Brisbane by Dr Eric Shaw, pathologist and Director of the Queensland Red Cross Blood Transfusion Service, and Dr Noel Gutteridge, a former Director and senior pathologist of Brisbane. Dr Kelsall's pioneering transfusion in Perth was a direct non-anticoagulated transfusion which was undertaken within minutes of birth and was completed within 5 min. The first volume-controlled exchange transfusion, in which the input-discard volumes were matched, used a plastic tube obtained from the Telephone Branch of the Postmaster General's Department, and employed citrated blood. These heroic exchanges (heroic for the infants and families concerned as well as for the operators) form a significant milestone in the history of blood transfusion, serology and preventive medicine in Australia.

After the broad brush of the topographical features of Australia and New Zealand had been mapped, the process of fine-tuning the geographic details of these countries continued. In parallel with this, a great wave of detailed scientific exploration proceeded and it was to these expeditions that medical men brought special skills. Surgeons played a special role because of the need of their practical skills in the field. Dozens of expeditions were commissioned throughout the nineteenth century. The aim of some was to search for minerals and document the fertility and water supply for pastoral and agricultural lands. Others had as their major raison d'etre the documentation of the many groups of animals and plants which populated these domains new to Western science. Surgeons and physicians were valued not only for their professional skills in the field, but for the pursuit of botany, zoology and geology, and in many cases for ethnological studies as well.

In October 1914, a new type of medical unit was added to the order of battle of the Australian Army's casualty evacuation chain. Designated the casualty clearing hospital, it was called a Casualty Clearing Station on the beach at Anzac Cove in the Gallipoli campaign. This unit was established as the most forward unit to provide emergency surgery, freeing the forward field ambulances from the necessity of holding wounded soldiers, a task which compromised their mobility and prevented them from moving with the brigades they supported. The Casualty Clearing Station was to be the most forward unit where specialist surgeons, anaesthetists, nurses, radiologists and a dentist were to be found. The 1st Australian Casualty Clearing Station (1ACCS) was raised in Hobart and consisted of 93 men including 7 doctors. After some seven weeks of training in camp, the new unit embarked for Egypt and the Gallipoli offensive. They landed on the beach at Anzac Cove at 11 a.m. on 25th April 1915, and remained on a 20 metre stretch of beach through eight months of the Gallipoli campaign. This paper reviews the first seven days of the Station's role at Anzac Cove, during which time this essentially inexperienced medical unit treated and evacuated an estimated 2700 wounded Australian and New Zealand soldiers. This paper also reviews the Commanding Officer's hitherto unpublished war diary and other archival and family records which add to the medical story of Anzac. This frightful baptism of mass casualty evacuation, undergone by the Australian Army Medical Corps, brings a perspective to the problems of mass disasters today.

Further experimental studies to determine the mass of venom injected by medically-significant Australian elapids are reported. The use of a modified enzyme immunoassay technique to measure venom injected during snake bite is presented. The feeding biting pattern of the Australian eastern brown snake (Pseudonaja textilis) is described. Using data from ten different snakes of this species, it is established that the mass of venom delivered in a first-bite is 4.69 +/- 0.85 mg (mean +/- S.E.) and a mean of 91% of the delivered venom is injected s.c. or into deeper tissues in a first-bite. For this species, the mass of venom delivered sequentially in a bite sequence falls to 1.32 +/- 0.94 mg in the third bite in such a sequence. For the Australian rough-scaled snake (Tropidechis carinatus), the mass of venom delivered in a first feeding bite is 6.15 +/- 2.23 mg, falling to a minimum of 1.92 +/- 0.61 mg in the third bite of a sequence. for the Australian death adder (Acanthophis antarcticus) the mass of venom delivered in a feeding bite is 41.95 +/- 16.13 mg for a first bite. Biting data is also presented for three species of the genus Pseudechis (the Australian mulga (king brown) and black snakes.

Secondary drowning (and near-drowning) is one of the post-immersion respiratory syndromes. It is defined as deterioration of pulmonary function that follows deficient gas exchange due to loss or inactivation of surfactant. A review of 94 consecutive cases of near-drowning in childhood showed that this syndrome occurred in five (5%) cases. Its onset was usually rapid and characterised by a latent period of one to 48 hours of relative respiratory well-being. It occurred more rapidly after immersion in fresh water. The two children immersed in salt water died of secondary drowning, while the three immersed in fresh water recovered completely. If it is anticipated, recognised, and treated vigorously prognosis of secondary drowning is good in fresh water cases but bad after salt water immersion.
