Concurrent hypereosinophilic syndrome and deep vein thrombosis after Pfizer-BioNTech COVID-19 vaccination: A case report.

Herein, we report a case of eosinophilia syndrome and deep vein thrombosis presenting concurrently after the administration of the BNT162b2 mRNA-based coronavirus disease 2019 (COVID-19) vaccine. It is extremely rare to have both hypereosinophilic syndrome and deep vein thrombosis simultaneously. Both are serious diseases and should be treated with caution.

Dietary Intake in Older Patients with Dementia Prior to and After the Onset of Coronavirus Disease 2019.

This was an observational study of hospitalized patients with dementia who developed COVID-19. The disease course, dietary intake, and disease severity (mild/severe) were evaluated. Twenty-nine patients with a median age of 84 years, with both mild (18) and severe conditions, (11) were evaluated. Mild group had decreased food intake from the day of symptom onset. In the severe group, the decline began the day before symptom onset. On day 30 of the disease, the median food intake of the mild group returned to levels observed prior to symptom onset, in contrast to those in the severe group.

Cavitary pulmonary Kaposi's sarcoma in AIDS.

Many different pulmonary diseases occur in human immunodeficiency virus-infected patients. This was a case of a cavity lesion, although differentiation was extremely difficult pictorially. This was a rare case that led to a definitive diagnosis because the cavity lesions were complicated by pneumothorax, and we could perform a biopsy.

Boerhaave syndrome due to excessive alcohol consumption: two case reports.

BACKGROUND: Spontaneous esophageal rupture, or Boerhaave syndrome, is a fatal disorder caused by an elevated esophageal pressure owing to forceful vomiting. Patients with Boerhaave syndrome often present with chest pain, dyspnea, and shock. We report on two patients of Boerhaave syndrome with different severities that was triggered by excessive alcohol consumption and was diagnosed immediately in the emergency room. CASE PRESENTATION: The patient in case 1 complained of severe chest pain and nausea and vomited on arrival at the hospital. He was subsequently diagnosed with Boerhaave syndrome coupled with mediastinitis using computed tomography (CT) and esophagogram. An emergency operation was successfully performed, in which a 3-cm tear was found on the left posterior wall of the distal esophagus. The patient subsequently had anastomotic leakage but was discharged 41 days later. The patient in case 2 complained of severe chest pain, nausea, vomiting, and hematemesis on arrival. He was suggested of having Boerhaave syndrome without mediastinitis on CT. The symptoms gradually disappeared after conservative treatment. Upper gastrointestinal endoscopy performed on the ninth day revealed a scar on the left wall of the distal esophagus. The patient was discharged 11 days later. In addition to the varying severity between the cases, the patient in case 2 was initially considered to have Mallory-Weiss syndrome. CONCLUSION: Owing to similar histories and symptoms, Boerhaave syndrome and Mallory-Weiss syndrome must be accurately distinguished by emergency clinicians. CT can be a useful modality to detect any severity of Boerhaave syndrome and also offers the possibility to distinguish Boerhaave syndrome from Mallory-Weiss syndrome.
