Review Case Reports
Severe extrapiramidal symptoms after nonintentional risperidone exposure in a child: case report and review of the literature.
Increase in use of atypical antipsychotics has been paralleled by an increase in the incidence of intentional and nonintentional overdose. Pediatric cases are uncommon, but may be severe. We describe a case of a child presenting with severe extrapiramidal symptoms, initially interpreted as seizures, caused by a nonintentional intoxication with risperidone, and review management options and the literature.

Fibromyalgia (FM) is a mysterious pain syndrome with progressive and widespread pain, explicit areas of tender points, stiffness, sleep disturbance, fatigue, and psychological distress without any obvious disease. FM is commonly perceived as a condition of central pain and sensory augmentation. There are documented functional abnormalities in pain and sensory processing in FM. ⋯ Pre-emptive analgesia and pro-active treatment may offer the momentum for acute pain control based on model of central sensitization and pain in FM. This review article on FM appraises the modern practice of multimodal therapy focus on both acute and chronic pain management. Meanwhile, the evolving nonpharmacological approach is summarized and stressed as an essential component of integrated care in FM.

We present a case of a significant insulin overdose that was managed by monitoring daily plasma insulin levels. A 39-year-old male with poorly controlled diabetes mellitus presented to the Emergency Department via emergency medical services after an attempted suicide by insulin overdose. In the attempted suicide, he injected 800 U of insulin lispro and 3800 U of insulin glargine subcutaneously over several parts of his abdomen. ⋯ He was transferred to an inpatient psychiatric facility 109 hours after initial presentation. Monitoring daily plasma insulin levels and adjusting treatment on a day-to-day basis in terms of basal glucose infusions provides fewer opportunities for episodic hypoglycemia. Furthermore, it was easier to predict daily glucose requirements and eventual medical clearance based on the plasma levels.

Currently, the Category (CAT) II regimen is recommended for patients who have failed the CAT I regimen. We have determined before that prevalence of multidrug-resistant tuberculosis (MDR TB) is relatively high among these patients. On the other hand, the retreatment success rate with CAT II in CAT I treatment failures and defaults is nearly 50%. ⋯ A retreatment strategy based on DST and replacing the Category II regimen with an intermediate regimen called revised CAT II may improve clinical outcomes among Category I treatment failures and defaults who found to have active, infectious MDR TB. This strategy significantly reduces delays to MDR TB diagnosis and to the initiation of MDR TB therapy. Success rate of this strategy is 62.2% and 72% in MDR TB and overall CAT I failure cases and defaulters, respectively.

Sulfobutylether-β-cyclodextrin (SBE-CD) is a pharmaceutical excipient known to bind verapamil. After intravenous administration, clearance of SBE-CD approximates glomerular filtration rate. We hypothesized that SBE-CD would complex with verapamil in vivo, enhance renal elimination, and increase time to death in a rat model of verapamil toxicity. ⋯ Verapamil poisoned rats treated with 2.25 g/kg of SBE-CD showed increased toxicity. We propose that this effect was related to the large hyperosmolar CD infusion combined with verapamil-induced cardiogenic shock. Additional studies are warranted to clarify the mechanism of increased toxicity in our study and to assess for potential beneficial effects at lower SBE-CD concentrations.
