Case ReportsEarly pathology in venom-induced consumption coagulopathy by Rhabdophis tigrinus (Yamakagashi snake) envenomation.
Objective:Rhabdophis tigrinus (Yamakagashi in Japanese) is a venomous non-front-fanged colubroid snake capable of inflicting envenoming with life-threatening defibrinating coagulopathy. However, because of the uncommon incidence of bites and tendency for late development of symptoms/signs, the early effects of the venom on the coagulation system are poorly known. Case report: We describe a boy bitten by a wild R. tigrinus and report his clinical course starting at 30 min after the bite. ⋯ Venom-induced consumption coagulopathy (VICC), which is sometimes reported as disseminated intravascular coagulation (DIC), subsequently improved rapidly. Discussion: We found that TAT is the earliest marker to detect R. tigrinus envenomation and subsequent VICC occurrence. Although rTM was effective in this case, further studies are necessary to prove its safety and efficacy.

Observational StudyButton battery exposures in Australian children: a prospective observational study highlighting the role of poisons information centres.
Button battery ingestion is a worldwide problem, with evidence of increasing harms and deaths in recent decades. Australian Poisons Information Centre (PIC) experience includes cases of treatment delay due to lack of healthcare professional recognition of risks, and/or lack of local resources. This study aims to characterise Australian button battery exposures, focusing on exposure circumstances, and preventable health system shortcomings. ⋯ Button battery exposures continue to be a problem in Australia. Data collected by PICs can provide useful information for public health and product safety initiatives. A PIC-led protocol to direct initial medical management of button battery exposures could reduce delays and improve outcomes.

Sodium hypochlorite is used as a bleaching and disinfecting agent and is commonly found in household bleach. ⋯ Accidental ingestion of household bleach is not normally of clinical significance. However, those who ingest a large amount of a dilute formulation or a high concentration preparation can develop severe, and rarely fatal, corrosive injury so prompt supportive care is essential as there is no specific antidote. Treatment primarily consists of symptom-directed supportive care.

Multicenter StudyShort-term glucose dysregulation following acute poisoning with organophosphorus insecticides but not herbicides, carbamate or pyrethroid insecticides in South Asia.
Ingestion of organophosphorus (OP) insecticides is associated with acute hyperglycaemia. We conducted a prospective study to determine whether glucose dysregulation on admission associated with ingestion of OP insecticides or other pesticides is sustained to hospital discharge or to 3-12 months later. ⋯ We found in this small prospective study that acute OP insecticide poisoning caused acute glucose dysregulation that was sustained to hospital discharge but had recovered by 3-12 months. Acute glucose dysregulation was related to defects in insulin action and secretion. This study did not address long-term risk of diabetes following acute OP insecticide poisoning, but could provide the data for a power calculation for such a study.

Climate change effect on flora and fauna has been scientifically documented, but the effect on North American venomous snakebites is unknown. The objectives were to examine Californian snakebite incidence and correlate with weather patterns and climate changes. ⋯ Patterns of precipitation and drought had a significant and predictive effect on snakebites in California over a 20-year period. Snakebite incidence decreased following drought, and increased after precipitation.
