Thyroid transcription factor 1 (TTF-1) is primarily expressed in lung and thyroid cancers, but it has also been observed in other cancers. A 60-year-old woman presented with worsening dyspnea, pleural effusion, lung metastases, a right ovarian tumor, and para-aortic intra-abdominal lymph node metastasis. ⋯ An adenocarcinoma positive for TTF-1 was identified, thus confirming the diagnosis of ovarian cancer. Our findings revealed that TTF-1 positivity does not always signify a lung cancer origin.

Objective Angiotensin receptor-neprilysin inhibitors (ARNIs) have been widely used as a treatment for heart failure. However, they have only been approved for the treatment of hypertension in a limited number of countries. We investigated the effect of ARNIs on arterial stiffness using the cardio-ankle vascular index (CAVI) in patients with hypertension to reveal the mechanism underlying cardiovascular interaction. ⋯ Forty-eight of the 50 patients (96%) were switched from angiotensin II receptor blockers (ARBs) due to inadequate antihypertensive control. Results The systolic blood pressure (BP), diastolic BP, and CAVI were significantly decreased by ARNI administration (systolic BP: 145 [135, 162] to 131 [123, 143] mmHg [p=0.000]; diastolic BP: 92 [78, 100] to 82 [74, 89] mmHg [p=0.000]; and CAVI: 9.9 [9.1, 10.5] to 9.5 [8.8, 10.2] mmHg [p=0.005], respectively). Conclusion Hypertension treatment with ARNIs may improve not only the blood pressure but also the CAVI, reducing the afterload on the heart.

Coronavirus disease 2019 (COVID-19) vaccines are effective in reducing the prevalence of this disease. However, some patients develop autoimmune diseases after vaccination. ⋯ Intestinal BD with trisomy 8, exacerbated by COVID-19, was treated with high-dose glucocorticoids and infliximab; however, surgical intervention was required. The findings of this case suggest that the COVID-19 vaccination may induce BD.

Objective Crohn's disease (CD) is a chronic inflammatory bowel disease that is associated with malnutrition. Sarcopenia is a malnutrition condition characterized by skeletal muscle loss that impairs the physical function. We investigated the clinical characteristics of patients with CD with sarcopenia and sarcopenic obesity (sarcopenic-o). ⋯ Conclusion Sarcopenia and sarcopenic-o are relatively common conditions among patients with CD. Sarcopenia can be predicted using the clinical parameters of BMI and CDAI. Sarcopenic-o can be a severe form of sarcopenia.

A 79-year-old man with smoldering multiple myeloma (MM) developed sudden severe thrombocytopenia and active bleeding. Since anti-GPIIb/IIIa autoantibodies were detected on the platelet surface, thrombocytopenia due to an autoimmune etiology was diagnosed. ⋯ MM is rarely associated with immune thrombocytopenic purpura (ITP). Although the underlying pathogenesis of MM and ITP remains elusive, anti-myeloma drugs might be beneficial.
