Death by chumbinho: aldicarb intoxication—regarding a corpse in decomposition

Abstract

Chumbinho is the popular name given to carbamate aldicarb (Temik), an insecticide commonly used in agriculture and highly toxic (LD50 = 0.9 mg/kg oral in rats) that has been sold clandestinely in several regions of Brazil. Chumbinho is sold illegally as raticide and is available in a formulation of small black granules which are easily mixed with food for criminal purposes, its use often being attributed to accidents and suicides, hence the importance of its inclusion in the toxicology studies of suspicious deaths. With the corpse putrefaction, many pathological and toxicological anatomical parameters are damaged or lost. This study emphasizes the importance of the gastric content observation, which in this case has, despite the advanced putrefaction, recognized the presence of chumbinho and guide its toxicological confirmation.

Characteristics of deaths by suicide in postmortem studies in Brazil: A systematic review and meta‐analysis

“…In the autopsy group (42 reports, k = 37, n = 16,231 cases of suicide; Table 2 and Table S2) five studies were single case reports (Durão & Machado, 2016; Picoli et al., 2020; Valente‐Aguiar et al., 2019; Valentini, 1965; Vasconcelos et al., 2019). The remaining 37 manuscripts (Anjos et al., 2021; Baptista & Borges, 2005; Baptista & Gomes, 2016; Cadurin et al., 2016; Camargo & Dos Santos, 2020; Carlini‐Cotrim et al., 1998; Carlini‐Cotrim & da Matta Chasin, 2000; Castro‐Espicalsky et al., 2020; Crespo et al., 2021; de Mendonça Neto et al., 2013; Franck et al., 2021; Franck, Monteiro, & Limberger, 2020; Franck & Pereira Limberger, 2020; Franck, Sgaravatti et al., 2020; Gianvecchio & Jorge, 2022; Gomes et al., 2010, 2018, 2022; Gonçalves et al., 2018, 2020; Gonsaga et al., 2012; Grossi & Vansan, 2002; Lira et al., 2020; Mello Jorge, 1981, 1982; Miziara, 2011; Nascimento et al., 2019; Oliveira et al., 2015, 2016; Parente et al., 2007; Paula et al., 2008; Ponce et al., 2008; Rocha et al., 2007; Rodrigues et al., 2008; Silva et al., 1999; Viana et al., 2008; Zerbini et al., 2012) were cross‐sectional reports of 32 samples.…”

Intoxicação com aldicarb "chumbinho": aspectos epidemiológicos, clínicos, terapêuticos, preventivos e educativos

“…Esse composto é a principal medida específica de tratamento, caracterizando-se como o antídoto mais apropriado para os casos médios e graves, que apresentem sintomas característicos da síndrome colinérgica. Em casos de o paciente apresentar grande quantidade de secreção, é recomendado que a atropinização se inicie antes da oxigenoterapia, pois a grande quantidade de secreção pode impossibilitar a administração do oxigênio (Ferreira et al, 2008;King;Aaron, 2015;Durão et al, 2016).…”
