EGD for Refractory Toxidromes: Is It Time to Add to the Algorithm?

Toxic ingestions are an increasing concern among pediatric patients in the United States. Less common, but troubling, are those patients with persistent toxicity symptoms despite stabilization, resuscitative, and decontamination efforts. We report a case of refractory serotonin toxicity in an adolescent for whom endoscopic removal of medication remnants led to the resolution of his clinical course. A 14-year-old male patient with anxiety and depression, treated with escitalopram and clonidine, presented to an outside hospital (OSH) emergency department (ED) with tonic-clonic seizure activity and altered mental status. Non-contrast head computed tomography (CT), complete blood count, and basic metabolic panel were unrevealing. Repeated seizure activity that occurred in the OSH ED prompted transfer to a tertiary pediatric care facility for ongoing management. Based on the constellation of symptoms (tachycardia, muscle rigidity, and lower extremity clonus) and his medication history, there was concern for serotonin toxicity. His clinical course worsened, despite treatment with midazolam and cyproheptadine, requiring intubation for respiratory failure. Because of his refractory symptoms and concern for ongoing medication side effects, on hospital day 4, he underwent an esophagogastroduodenoscopy (EGD), which revealed 20 partially digested pills firmly adhered to the gastric mucosa. The pill fragments were removed and whole bowel irrigation was started, and the patient improved rapidly, allowing for extubation within 24 hours. An EGD is not routinely used for the management of toxic ingestions. In addition to this case, evidence from prior case reports supports the judicious use of EGD as a diagnostic and therapeutic decontamination modality for severe toxicities.

Apnea with ketamine sedation in a patient with severe anorexia nervosa: A case report.

BACKGROUND: There is a paucity of literature around sedation and anesthesia in patients with severe anorexia nervosa. Chronically malnourished patients are known to have myopathy, neuropathy, and altered neurotransmitter signaling. Ketamine is a non-competitive N-methyl-D-aspartate (NMDA) receptor antagonist that is an established general anesthetic and short-acting dissociative analgesic agent. It generally has a reassuring adverse event profile and rarely has been reported to result in apnea. We aim to raise awareness of this untoward adverse event in patients with severe anorexia nervosa among sedation providers and those referring patients for hospitalization or sedation. CASE PRESENTATION: We describe an episode of apnea, a rare adverse event of ketamine, which was given for procedural sedation to a severely malnourished 13-year-old female with anorexia nervosa, generalized anxiety disorder, and high-functioning autism spectrum disorder. She had no history of apnea nor of ketamine sedation. She was given a standard dose of ketamine and had no other central nervous system depressants within 24 h. Within 1 min after slow medication administration, she had a 9-min period of apnea without laryngospasm. She was supported with bag-valve-mask ventilation throughout this period and did not require intubation. She returned to baseline shortly after procedural sedation. CONCLUSIONS: This case describes apnea after ketamine sedation in a patient with severe anorexia nervosa. It supports the importance of a thorough pre-procedure review of a patient's underlying medical problems and the consideration of how sedatives may interact with these conditions. We aim to alert those who care for this complex population of the possible altered neurotransmitters, myopathy, and adverse response to sedation, anesthetics, and analgesics.

A rare case of neonatal meningoencephalitis from Paenibacillus thiaminolyticus.

Paenibacillus infections can be life threatening and are being reported with increasing incidence. There are only a few case reports of infections and are mainly described in patients who are immunocompromised, injection drug users, or those with prosthetic devices. Due to improved testing and identification, it appears that these infections may not be as rare as once perceived. We present a case of a 16-day-old term neonate who presented with status epilepticus and was found to have Paenibacillus thiaminolyticus meningoencephalitis. The patient was successfully treated with a combination of ampicillin and ceftazidime then meropenem. To our knowledge, this is the first reported case of an infant in the United States who survived this serious invasive infection. We also present an option for therapy given the difficulty treating invasive intracranial infections.
