Adrenal Crisis Mimicking COVID-19 Encephalopathy in a Teenager with Craniopharyngioma.

There is an increasing number of reported cases with neurological manifestations of COVID-19 in children. Symptoms include headache, general malaise, ageusia, seizure and alterations in consciousness. The differential diagnosis includes several potentially lethal conditions including encephalopathy, encephalitis, intracranial hemorrhage, thrombosis and adrenal crisis. We report the case of a 17-year-old boy with a positive antigen test of COVID-19 who presented with fever for one day, altered mental status and seizure, subsequently diagnosed with adrenal insufficiency. He had a history of panhypopituitarism secondary to a suprasellar craniopharyngioma treated with surgical resection; he was treated with regular hormone replacement therapy. After prompt administration of intravenous hydrocortisone, his mental status returned to normal within four hours. He recovered without neurologic complications. Adrenal insufficiency can present with neurological manifestations mimicking COVID-19 encephalopathy. Prompt recognition and treatment of adrenal insufficiency, especially in patients with brain tumors, Addison's disease or those recently treated with corticosteroids, can rapidly improve the clinical condition and prevent long-term consequences.

Diabetes Is Associated with Clinical Decompensation Events in Patients with Cirrhosis.

OBJECTIVES: Liver cirrhosis is a leading cause of morbidity and mortality in the USA. Diabetes is common and increasing in incidence. Patients with compensated cirrhosis and diabetes may be at greater risk of clinical decompensation. We examined the risk of decompensation among a large sample of working-aged insured patients dually diagnosed with compensated cirrhosis and diabetes. METHODS: This retrospective study used MarketScan® Commercial Claims and Encounters and Medicare Supplemental Databases (2000-2013). Decompensation events included incident ascites, spontaneous bacterial peritonitis, variceal bleeding, hepatic encephalopathy, acute renal failure, and hepatocellular carcinoma. Dually diagnosed patients were defined as patients with cirrhosis and diabetes using previously published ICD-9 coding strategies. Adjusted odds ratios (ORs), hazard ratios (HRs), and confidence intervals (CI) were estimated using logistic regression and Cox proportional hazard models. RESULTS: Of 72,731 patients with compensated cirrhosis, 20,477 patients (28.15 %) were diagnosed with diabetes. After controlling for patient characteristics and medication usage, the odds of developing any decompensation event were 1.14 times higher for patients with cirrhosis and diabetes than for patients with cirrhosis only (95 % CI 1.08-1.21, P value <0.01). In the Cox proportional hazard model, patients who were dually diagnosed with diabetes had a 1.32 times higher HR (95 % CI 1.26-1.39, P value <0.01) after controlling for time-to-event. CONCLUSIONS: Patients dually diagnosed with compensated cirrhosis and diabetes had a higher risk of having decompensation events. Careful management of diabetes in patients with liver disease may reduce the risk of clinical decompensation in this population.

Positron emission tomography and stage migration in head and neck cancer.

IMPORTANCE: Since 2001, there has been a rapid adoption of positron emission tomography (PET) for diagnosis and American Joint Committee on Cancer (AJCC) staging of head and neck cancer (HNC) without data describing improved clinical outcomes. OBJECTIVE: To determine the association between increased use of PET and stage and/or survival for patients with HNC in the managed care environment. DESIGN, SETTING, AND PARTICIPANTS: Adult patients diagnosed as having HNC (n = 958) from 2000 to 2008 at 4 integrated health systems were identified via tumor registries linked to administrative data. The AJCC stage distribution, patient and treatment characteristics, and survival between pre-PET era (2000-2004) vs PET era (2005-2008) and use of PET vs no use of PET during the PET era were compared. The AJCC stages were categorized to represent localized (stage I or II), locally advanced (stage III, IVA, or IVB), and metastatic (stage IVC) disease. INTERVENTIONS: Treatments were determined by billing codes for surgery, radiation treatment, and chemotherapy. MAIN OUTCOMES AND MEASURES: The primary outcome for this study was the use of PET. Secondary outcomes included treatment received and 2-year survival. A logit model estimated the effects of PET on diagnosis of locally advanced disease. Kaplan-Meier estimates described overall survival differences between PET and non-PET. Cox regression evaluated the association of PET on survival in patients with locally advanced disease. RESULTS: An association between PET and locally advanced disease was found (odds ratio, 2.86 [95% CI, 1.90-4.29) (P < .001). Two-year overall survival for patients with locally advanced disease with and without PET was 52% and 32%, respectively (P = .004), but there was no difference for all stages (P = .69). On Cox proportional hazard regression, PET had no association with survival in patients with locally advanced disease (hazard ratio, 1.208 [95% CI, 0.778-1.877]) (P = .40). CONCLUSIONS AND RELEVANCE: The increasing use of PET among patients with HNC is associated with a greater number of patients with higher-stage disease and a dilution of the population with higher-stage disease with patients who have a better prognosis. Thus, the improved survival in patients with locally advanced disease likely reflects selection bias and stage migration. Further research on PET use among patients with HNC is necessary to determine if it results in improved treatment for individual patients.
