A 29-year-old man was bitten on the forearm by a wild Gila monster. Radiographs demonstrated subcutaneous air. During a period of observation, erythema and edema progressed from the forearm to the axilla and he developed a significant leukocytosis. No purulence was found upon surgical evaluation. We hypothesize that air was introduced into the wound by the "pulsing," chewing-like action that the Gila monster made while it was attached to the man's forearm.

Animal venoms are natural products that have served as a source of novel molecules that have inspired novel drugs for several diseases, including for metabolic diseases such as type-2 diabetes and obesity. From venoms, toxins such as exendin-4 () and crotamine () have demonstrated their potential as treatments for obesity. Moreover, other toxins such as Phospholipases A and Disintegrins have shown their potential to modulate insulin secretion in vitro.

Neoplasia in the Gila monster () is not commonly investigated, and literature regarding the prevalence and type of neoplasms that affect this species is sparse. Gastrointestinal tract adenocarcinoma (GTA) in particular has only been reported twice in Gila monsters, once in the small intestine and once in the colon. In this case series, 50% (7/14) of the Gila monsters presented to the pathology service at Smithsonian's National Zoo and Conservation Biology Institute (SNZCBI) over the span of 26 yr (1997-2023) were found to have intestinal and/or colonic adenocarcinoma.

Despite their evolutionary novelty, lizard venoms are much less studied in comparison to the intense research on snake venoms. While the venoms of helodermatid lizards have long been assumed to be for defensive purposes, there is increasing evidence of toxic activities more useful for predation than defence (such as paralytic neurotoxicity). This study aimed to ascertain the effects of , , and lizard venoms on the coagulation and cardiovascular systems.

Reptiles exhibit a variety of modes of sex determination, including both temperature-dependent and genetic mechanisms. Among those species with genetic sex determination, sex chromosomes of varying heterogamety (XX/XY and ZZ/ZW) have been observed with different degrees of differentiation. Karyotype studies have demonstrated that Gila monsters (Heloderma suspectum) have ZZ/ZW sex determination and this system is likely homologous to the ZZ/ZW system in the Komodo dragon (Varanus komodoensis), but little else is known about their sex chromosomes.

Neurodegenerative disorders, which affect millions worldwide, are marked by a steady decline of neurons that are selectively susceptible. Due to the complex pathological processes underlying neurodegeneration, at present, there is no viable therapy available for neurodegenerative disorders. Consequently, the establishment of a novel therapeutic approach for such conditions is a clinical void that remains.
