Salicylate Poisoning and Rebound Toxicity.

Salicylate exposure and toxicity are associated with a myriad of symptoms and signs, and a comprehensive knowledge of diagnosing and treating salicylate poisoning is needed. Here, we present a case of a 29-year-old female with a past medical history of schizoaffective disorder and bipolar disorder with multiple suicide attempts brought to our hospital, Nassau University Medical Center, East Meadow, by the Emergency Medical Service (EMS) due to an intentional overdose of 300 pills of acetylsalicylic acid. She had mixed acid-base disturbance with respiratory alkalosis and metabolic acidosis. She was started on bicarbonate infusion in the emergency department to maintain a blood pH of 7.5 and to maintain a urine pH of more than 7.5. As her salicylate levels were 98.2 at admission with altered mental status, she was started on slow, low-efficiency hemodialysis. A few hours later, she developed a rebound increase in salicylate levels to 129, associated with a change in mental status and the patient was more confused. She was started on regular hemodialysis with improvement in mental status and elimination of salicylate steadily. Given the extensive nature of toxic effects, a patient with severe salicylate toxicity can deteriorate rapidly and can be challenging to manage. As there is no specific antidote for aspirin, the goals of therapy depend primarily on limiting the absorption of salicylate, enhancing elimination, and providing supportive care. Monitoring the acid-base status and serum salicylate levels closely and monitoring for rebound increase in salicylate levels is of paramount importance. Aggressive hydration to maintain euvolemia, alkalinization, aggressive replenishment of potassium and magnesium, activated charcoal to decrease absorption, and hemodialysis remain the cornerstones of treatment.

Pulmonologist Education of the Teach-to-Goal Inhaler Technique for Those With Asthma and COPD.

BACKGROUND: Inhaler education for patients with asthma and patients with COPD is typically provided by non-pulmonologists. We studied inhaler education by pulmonologists to determine changes in clinical outcomes and inhaler use. METHODS: This was a retrospective study of 296 subjects diagnosed with asthma, COPD, or both that evaluated use of inhaler technique education and its impact on (1) inhaler/dosage change consisting of dosage change in the same class of inhaler and/or change in number of inhalers, (2) forced expiratory volume in one second/forced vital capacity (FEV1/FVC%), (3) disease symptom control, (4) out-patient visits, (5) urgent care visits (6) emergency department visits, and (7) hospital admissions. One group received inhaler technique education by a pulmonologist while the other group did not. RESULTS: The pulmonologist inhaler technique-educated group had significantly decreased relative risk for inhaler/dosage increase (relative risk 0.57 [95% CI 0.34-0.96], P = .03) and significantly increased odds for symptom control (odds ratio 2.15 [95% CI 1.24-3.74], P = .01) at 1-y follow-up as compared to the no education group. No differences occurred for FEV1/FVC%, out-patient visits, urgent care visits, emergency department visits, and hospital admissions. CONCLUSIONS: Pulmonologist education of inhaler technique for patients with asthma and patients with COPD was associated with decreased relative risk for inhaler/dosage increase and increased odds for symptom control. We recommend pulmonologists provide education of inhaler technique to patients with asthma and patients with COPD and not rely on non-pulmonologist education alone. Prospective research is needed to confirm the importance of proper inhaler techniques.

An Oncological Emergency: Severe Type B Lactic Acidosis From Warburg Effect in Diffuse Large B-cell Lymphoma.

Lactic acidosis is the most common anion gap metabolic acidosis in critically ill patients. Type B lactic acidosis is most commonly seen with hematological malignancies, especially lymphomas. It is considered an oncological emergency and is associated with high mortality and poor outcomes if not treated promptly. Here, we present the case of a 48-year-old male who developed Type B lactic acidosis secondary to newly diagnosed diffuse large B-cell lymphoma. This case highlights the importance of including Type B lactic acidosis in the differential diagnosis in a patient with unexplained lactic acidosis and hypoglycemia with otherwise vague symptoms and the need for a thorough search for quick diagnosis and early management.
