Background Hiccups are involuntary diaphragmatic muscle contractions with early glottis closure terminating inspiration. They are classified into two types: acute (<48 hours) and persistent (>48 hours). COVID-19 is the defining health crisis of our generation. Although there are common symptoms of the disease (e.g. fever, cough), several atypical presentations have appeared as the pandemic has evolved. Here, we present a patient with COVID-19 presenting with fever, sore throat, and persistent hiccups. Methods and Results A 48-year-old man presented to the hospital with a seven-day history of persistent hiccups, fever, and sore throat. Physical examination was unremarkable and abdominal ultrasound showed gaseous abdominal distension. Laboratory values were remarkable for elevated C-reactive protein, ferritin, and lactate dehydrogenase levels. Computed tomography of the chest showed bilateral subpleural areas of ground-glass attenuation and crazy-paving pattern. A COVID-19 test was positive, and hydroxychloroquine, oseltamivir, baclofen, and symptomatic treatment were initiated. The hiccups improved, and the patient was discharged home after ten days. Conclusion Physicians should maintain a high level of suspicion and be aware of atypical presentations of COVID-19.

Despite the promising results from the placement of covered or uncovered self-expandable metallic stent (SEMS) as a nonsurgical therapeutic option for the malignant gastric outlet obstruction (GOO), the long patency of the stent is still limited because of stent-induced tissue hyperplasia. Here, a local heat treatment using a nanofunctionalized SEMS is proposed for suppressing stent-induced tissue hyperplasia during GOO treatment. Highly efficient photothermal gold nanoparticle (GNP) transducer-coated SEMSs (GNP-SEMSs) were prepared for local heat treatment in rat gastric outlet. The in vivo heating temperature in rat gastric outlet model was evaluated and compared with in vitro heating temperature. Three groups of our developed 45 rat gastric outlet models were used: group A, noncoated SEMS only; group B, GNP-SEMS plus local heating; and group C, GNP-SEMS only to investigate in vivo efficacy of GNP-SEMS mediated local heating. Ten rats per group were sacrificed for 4 weeks, and five rats per group were sacrificed immediately after local heat treatment. The in vivo heating temperature was found to be 10.8% lower than the in vitro heating temperatures. GNP-SEMSs were successfully placed through a percutaneous approach into the rat gastric outlet (n = 45). The therapeutic effects of GNP-SEMS were assessed by histologic examination including hematoxylin-eosin, Masson trichrome, immunohistochemistry (TUNEL and CD31), and immunofluorescence (Ki67), and the results showed significant prevention of tissue hyperplasia following stent placement without adjacent gastrointestinal tissue damage. GNP-SEMS-mediated local heating could be an alternative therapeutic option for the suppression of tissue hyperplasia following stent placement in benign and malignant GOOs.
