Landlocked shad is a freshwater clupeid fish ( Alosa fallax lacustris ) whose consumption is associated with the risk of scombrotoxin poisoning. Traditionally, fresh shad are subjected to an artisanal processing procedure, consisting of dry salting and maturation under pressure, to give a fish product named missoltino , which is stored in large metallic barrels and is sold to local consumers and restaurants. In recent years, the introduction of modern food packaging technologies has enabled this product to also be distributed in shops and supermarkets...

BACKGROUND: Labeling prohibits delivery of insulin at the site of subcutaneous continuous glucose monitoring (CGM). Integration of the sensing and insulin delivery functions into a single device would likely increase the usage of CGM in persons with type 1 diabetes. METHODS: To understand the nature of such interference, we measured glucose at the site of bolus insulin delivery in swine using a flexible electrode strip that was laminated to the outer wall of an insulin delivery cannula...

Trehani Mary Fonseka, Gerald P McKinley, Sidney H Kennedy
Prior to the mid-1980s, suicide in Indigenous population in Northwestern Ontario, Canada, was rare, occurring at rates of 1-2 per year among over 20 communities. By the early 1990s, the completed suicide rates in the same communities were among the highest in the world. Prior to the outbreak of the suicide epidemic, sniffing of gasoline containing tetraethyl was common in many communities. Existing literature confirms that tetraethyl lead poisoning is associated with alterations to the amyloid-β protein precursor and amyloid-β as well as the 5-HT-1B receptor...

John Jacob Cannell
An increasing amount of evidence points to the possibility that gestational and early childhood vitamin D deficiency [25(OH)D < 40 ng/ml] cause some cases of autism. Vitamin D is metabolized into a seco-steroid hormone that regulates about 3% of the 26,000 genes in the coding human genome. It is also a neurosteroid that is active in brain development, having effects on cellular proliferation, differentiation, calcium signaling, neurotrophic and neuroprotective actions; it also appears to have an effect on neurotransmission and synaptic plasticity...

Ciguatoxins are produced by toxic benthic dinoflagellates and cause ciguatera fish poisoning worldwide, but the toxic effects on developing marine fish have not been well investigated. The Pacific ciguatoxin (P-CTX-1), is a potent sodium channel agonist, which is one of the most toxic members among all CTXs. This study evaluated the toxic effects of microinjecting purified Pacific ciguatoxin-1 (P-CTX-1) on embryonic development of marine medaka Oryzias melastigma. A lower 96h-LD50 value was estimated for eleuthero-embryos (1...

Clostridium perfringens is a spore-forming bacterium and a major cause of bacterial food-borne illness. In this study, we evaluated the inhibitory effects of chitosan against spore germination, spore outgrowth and vegetative growth of C. perfringens food poisoning (FP) isolates. Chitosan of differing molecular weights inhibited germination of spores of all tested FP isolates in a KCl germinant solution containing 0.1 mg/ml chitosan at pH 4.5. However, higher level (0.25 mg/ml) of chitosan was required to effectively arrest outgrowth of the germinated C...

Caregiver-fabricated illness in a child is a form of child maltreatment caused by a caregiver inducing a child's illness, leading to unnecessary and potentially harmful medical procedures and treatments. This condition can result in significant morbidity and mortality. We present the case of three siblings in Tunisia who were poisoned with chloralose by their own mother. The symptoms that the children presented with led to misdiagnoses, which resulted in the death of two of the children. Characteristics of the clinical presentation are articulated, followed by a discussion of the legal measures that apply to the offender and the role of physicians, nurses, and medicolegal experts involved in such a complex medical situation...

Hydrocarbons are a wide-ranging group of flammable chemicals and are often used in suicide attempts either by ingestion or as accelerant in self-immolation. In this case study, we present a 37-year-old female who suffered 6% TBSA partial-thickness burns to her perineum and buttocks, which she claims resulted from diarrhea after ingesting a bottle of lighter fluid. The patient underwent decontamination and medical treatment for her burns and during her inpatient stay, it became apparent that the burns were more likely sustained from an intentional rectal administration of lighter fluid...

Protists kill their bacterial prey using toxic metals such as copper. Here we hypothesize that the metalloid arsenic has a similar role. To test this hypothesis, we examined intracellular survival of Escherichia coli (E. coli) in the amoeba Dictyostelium discoideum (D. discoideum). Deletion of the E. coli ars operon led to significantly lower intracellular survival compared to wild type E. coli. This suggests that protists use arsenic to poison bacterial cells in the phagosome, similar to their use of copper...

Childhood Lead Poisoning Prevention Programs throughout the U.S. have addressed childhood lead poisoning by implementing primary and secondary prevention efforts. While many programs have helped increase screening rates, in some states children under the age of six still have not been tested for lead. This study aims to identify the barriers to childhood blood lead testing and develop a strategy to increase the number of children tested. Clark County physicians who work with children six and under were surveyed about blood lead level (BLL) testing practices, particularly, adherence to Centers for Disease Control and Prevention (CDC) guidelines, and parental compliance with orders to have their children tested to determine their blood lead levels...
