Chemotherapy-induced neuropathy and pain in pediatric oncology patients: impact of combination therapies.

Unlabelled: Chemotherapy-induced peripheral neuropathy (CIPN) and associated pain are prevalent adverse effects of pediatric cancer treatment, significantly affecting the patient's quality of life. Their impact and risk factors have yet to be assessed in our country. This study aimed to assess the prevalence and clinical characteristics of CIPN, as well as to explore associations with patient- and treatment-related variables, within a cohort of Argentinean pediatric oncology patients.

Changes in the expression of endocannabinoid system components in an experimental model of chemotherapy-induced peripheral neuropathic pain: Evaluation of sex-related differences.

Chemotherapy-induced neuropathic pain is a serious clinical problem and one of the major side effects in cancer treatment. The endocannabinoid system (ECS) plays a crucial role in regulating pain neurotransmission, and changes in the expression of different components of the ECS have been reported in experimental models of persistent pain. In addition, sex differences have been observed in ECS regulation and function.

Further evidence of anxiety- and depression-like behavior for total genetic ablation of cannabinoid receptor type 1.

Cannabinoid receptor type 1 (CB1R) is the most abundant cannabinoid receptor in central nervous system. Clinical studies and animal models have shown that the attenuation of endocannabinoid system signaling correlates with the development of psychiatric disorders such as anxiety, depression and schizophrenia. In the present work, multiple behavioral tests were performed to evaluate behaviors related to anxiety and depression in CB1R and CB1R.

Neuronal and synaptic morphological alterations in the hippocampus of cannabinoid receptor type 1 knockout mice.

Cannabinoid receptor type 1 (CB1R) modulates synaptic activity and is widely distributed in brain areas such as the hippocampus, cerebellum, cerebral cortex, and striatum, among others. CB1R is involved in processes such as memory, learning, motor coordination, and mood. Genetic deletion of CB1R causes behavioral alterations.

Anxious Behavior of Adult CD1 Mice Perinatally Exposed to Low Concentrations of Ethanol Correlates With Morphological Changes in Cingulate Cortex and Amygdala.

Perinatal ethanol (EtOH) exposure is associated with high incidence of behavioral disorders such as depression and anxiety. The cerebral areas related with these consequences involve the corticolimbic system, in particular the prefrontal cortex, hippocampus, amygdala, and cingulate cortex, although the latter has not been thoroughly studied yet. Different animal models of prenatal or perinatal EtOH exposure have reported morphofunctional alterations in the central nervous system, which could explain behavioral disorders along life; these results focus on youth and adolescents and are still controversial.
