- Does the hyperglycemia impact on COVID-19 outcomes depend upon the presence of diabetes? An observational studyPublication . Manique, Inês; Matias, Alexandra Abegão; Bouça, Bruno; Rego, Teresa; Cortez, Luísa; Sabino, Teresa; Panarra, António; Rizzo, Manfredi; Silva-Nunes, JoséDiabetes mellitus (DM) has emerged as a major risk factor for COVID-19 severity and SARS-CoV-2 infection can worsen glycemic control and may precipitate new-onset diabetes. At-admission hyperglycemia (AH) is a known predictor for worse outcomes in many diseases and seems to have a similar effect in COVID-19 patients. In this study, we aimed to assess the impact of AH regardless of pre-existing diabetes mellitus and new-onset diabetes diagnosis in the clinical severity of COVID-19 inpatients in the first months of the pandemic. A retrospective monocentric study on 374 COVID-19 inpatients (209 males) was developed to assess associations between AH (blood glucose levels in the Emergency Department or the first 24 h of hospitalization greater than 140 mg/dL) and severity outcomes (disease severity, respiratory support, admission to Intensive Care Unit (ICU) and mortality) in patients with and without diabetes. Considering diabetic patients with AH (N = 68;18.1%) there was a correlation with COVID-19 severity (p = 0.03), invasive mechanical ventilation (p = 0.008), and ICU admission (p = 0.026). No correlation was present with any severity outcomes in diabetic patients without AH (N = 33; 8.8%). All of the New-onset Diabetes patients (N = 15; 4%) had AH, and 12 had severe COVID-19; additionally, five patients were admitted to the ICU and three patients died. However, severity outcomes did not reach statistical correlation significance in this group. In nondiabetic patients with AH (N = 51; 13.6%), there was a statistically significant association with the need for oxygen therapy (p = 0.001), invasive mechanical ventilation (p = 0.01), and ICU admission (p = 0.03). Our results support data regarding the impact of AH on severity outcomes. It also suggests an effect of AH on the prognosis of COVID-19 inpatients, regardless of the presence of pre-existing diabetes or new-onset diabetes. We reinforce the importance to assess at admission glycemia in all patients admitted with COVID-19.
- Horner’s syndrome after an ultrasound-guided fine-needle aspiration puncture of a thyroid nodulePublication . Matias, Alexandra Abegão; Sabino, Teresa; Silva-Nunes, JoséHorner’s syndrome is a rare condition that results from damage to the oculosympathetic chain. The classical presentation consists of miosis, unilateral ptosis, and hemifacial anhidrosis due to a deficiency of sympathetic activity. Although it has been described as a result of different types of trauma, we present the first clinical report of Horner’s syndrome that was developed after a fine-needle aspiration puncture of a thyroid nodule. A 48-year-old woman with a non-toxic multinodular goiter underwent an ultrasound-guided fine-needle aspiration for the second time for a nodule located in the right thyroid lobe. Four hours after the procedure, she developed homolateral eyelid ptosis, miosis, and enophthalmos and went to the emergency department for observation. Structural causes potentially related to the manifestations were excluded. Horner’s syndrome was diagnosed, and the patient was discharged with symptomatic measures. Three months after the event, the patient reported partial improvement. We discuss the pathophysiology associated with Horner’s syndrome, the association with thyroid diagnostic and therapeutic procedures, clinical presentation, patient management, and prognosis. Although fine-needle aspiration of a thyroid nodule has few associated complications, Horner’s syndrome should be considered when the patient develops ophthalmologic symptoms. Preventive measures should be observed to minimize its occurrence. Horner’s syndrome is a potential complication of diagnostic and therapeutic procedures directed at the thyroid gland, including ultrasound-guided fine-needle aspiration. It is characterized by eyelid ptosis, miosis, enophthalmos, and anhidrosis homolateral to the lesion. The diagnosis of Horner’s syndrome is clinical after excluding structural causes and establishing the temporal relationship between the procedure and the manifestations. There is no targeted treatment for Horner’s syndrome, but it can be prevented.
