Background: Potentially nephrotoxic drugs play an important role in acute kidney injury (AKI) in children. In the previous pharmacovigilance study, we found a statistical correlation between diazepam and AKI in children, but the causality needs to be further verified.
Methods: An observational cohort study was conducted to investigate the association between diazepam exposure and the risk of AKI in hospitalized children. The exposed group received diazepam while the control group did not. The outcome was AKI in accordance with the Kidney Disease Improving Global Outcomes (KDIGO) guidelines. Logistic regression was used to explore the association between diazepam exposure and the risk of AKI in children after adjusting for covariates.
Results: A total of 3018 hospitalized children were included, 148 in the diazepam group and 2870 in the control group. After adjusting for covariates, diazepam exposure was associated with an increased risk of AKI in children (OR = 1.85, 95%CI: 1.11-3.09, P = 0.019). Multivariate logistic regression showed that age (P < 0.001), low baseline serum creatinine (P < 0.001), chronic kidney disease (P = 0.039), diuretics (P = 0.009), Non-steroidal anti-inflammatory drugs (NSAIDs, P = 0.046), proton pump inhibitors (P = 0.007) and vasoactive drugs (P = 0.007) were risk factors for diazepam-associated AKI in children.
Conclusions: The use of diazepam in children is associated with an increased risk of AKI. The risk factors for diazepam-associated AKI in children included age, low baseline serum creatinine, chronic kidney disease, diuretics, NSAIDs, proton pump inhibitors, and vasoactive drugs.

From cultural remedy to medical emergency: a case report of camphor toxicity in a one-year-old male patient.

Hospital Pediátrico Dr. Hugo Mendoza, Santo Domingo, Dominican Republic.
Background: Camphor (CMP) is widely used for cultural and medicinal purposes in regions like the Middle East, India, Nigeria, and Latin America. Despite its traditional uses, CMP presents serious toxic risks, particularly in infants and children, where even small ingested doses can lead to life-threatening symptoms. This case report highlights the risk posed by camphor ingestion in a pediatric patient, emphasizing its relevance to healthcare providers in regions where camphor is commonly used.

While multiple oral medications are used to treat dystonia, limited information exists on current prescribing practices. This study analyzes real-world prescribing practices for pediatric dystonia in the United States, evaluating prescription frequency, dosing, and the impact of comorbidities. Oracle electronic health record real-world data were queried from 2014 to 2019 for encounters of patients under age 18 with a dystonia diagnosis and available medication records.

Ischemia-reperfusion (IR) is a leading cause of acute kidney injury (AKI), and pigs are commonly used in preclinical AKI models. However, existing models often vary in the methods used to induce ischemia, and the resulting AKI tends to be mild-to-moderate. Moreover, follow-up is often performed under volatile anesthesia, which, in contrast to total intravenous anesthesia (TIVA), can induce malignant hyperthermia and cause hemodynamic instability.
