Review Case Reports
Spinal Cord Infarction in an Adolescent with Protein S Deficiency: A Case Report and Literature Review.
Protein S deficiency causes spinal cord infarction in rare cases. We herein report the first case of severe cervicothoracic cord infarction in an adolescent with protein S deficiency. A 16-year-old boy presented with neck pain, four-limb paralysis, and numbness. ⋯ Protein S antigen and activity were decreased. The patient was diagnosed with protein S deficiency-associated cervicothoracic cord infarction, which was treated with anticoagulation. Protein S deficiency should be considered as a potential cause of spinal cord infarction in young healthy patients and should be appropriately treated with anticoagulation.

Cryptococcal meningitis is a critical disease that occasionally involves immunosuppressed patients. We herein report a 79-year-old Japanese man who received low-dose prednisolone therapy for neurosarcoidosis and panhypopituitarism. ⋯ After the diagnosis of cryptococcal meningitis, we successfully treated the patient with a recommended treatment regimen. When an immunocompromised patient presents with a subacute fever accompanying any central nervous symptoms, cryptococcal meningitis should be screened for.

Pregnancy is a known risk factor for amebic enteritis, which develops into potentially fatal fulminant amebic enteritis in some cases. We describe a case of a 27-year-old non-immunosuppressed pregnant woman with fulminant amebic enteritis complicated with cytomegalovirus enteritis. ⋯ It is difficult to diagnose amebic enteritis, especially in a non-endemic area. Amebic enteritis must be considered as a differential diagnosis for refractory diarrhea with bloody stools in women in the perinatal period, even those without immunosuppression.

Bevacizumab, a monoclonal antibody against vascular endothelial growth factor, may be associated with arterial embolisms. We herein report a case of acute myocardial infarction caused by coronary embolism during combination chemotherapy with mFOLFOX-6 and bevacizumab in a patient with metastatic colon cancer. ⋯ Sole thromboaspiration was successfully performed; the final angiogram demonstrated no stenosis in the right coronary artery. Bevacizumab may be associated with acute coronary syndrome in patients with coronary risk factors, despite no significant coronary narrowing.

Case Reports
Mid-ventricular Obstructive Cardiomyopathy after Takotsubo Cardiomyopathy: A Case Report.
A 93-year-old woman was transferred to our hospital for lightheadedness. She had had Takotsubo cardiomyopathy for seven years. ⋯ The patient was therefore diagnosed with mid-ventricular obstructive cardiomyopathy with a large apical aneurysm and paradoxical flow. The present case suggests that Takotsubo cardiomyopathy may become mid-ventricular obstructive hypertrophic cardiomyopathy without change in its structure.
