Clostridium paraputrificum bacteremia is very rare, and its clinical importance is poorly understood. An 86-year-old man was receiving lascufloxacin therapy for acute pharyngolaryngitis before presenting to our emergency department with a recurrent fever. Two sets of blood cultures on admission revealed C. paraputrificum. ⋯ Colonoscopy revealed a rectal tumor. Rectal tumor and microbial substitutions caused by antibiotics may have led to bacteremia. When treating C. paraputrificum bacteremia, physicians should be mindful of coexisting gastrointestinal disorders and a history of antibiotic administration.

Objective Of the highly accurate tests for current Helicobacter pylori infection, the urea breath test (UBT) and stool antigen test (SAT) are noninvasive and do not require endoscopy. We conducted a prospective study to evaluate the accuracy of the newly developed SAT in a medical checkup setting. ⋯ Conclusion The newly developed H. pylori SAT may be useful for diagnosing H. pylori infection. Patients should be suspected of being infected even after H. pylori eradication if they have a high cutoff index in this test.

Case Reports
Osmotic Demyelination Syndrome in a Patient with Diabetic Ketoacidosis Despite No Rapid Sodium Correction.
Osmotic demyelination syndrome (ODS) occurs in patients with diabetes and hyponatremia. We herein report a case of ODS with chorea detected on serial magnetic resonance imaging (MRI), despite no prompt hyponatremia correction. ⋯ Clinicians should consider ODS in patients with DKA and a hyperosmolar hyperglycemic state displaying unconsciousness and neurological manifestations, including chorea, even without substantial changes in serum sodium levels. An MRI re-examination can help capture missing ODS complications.

Case Reports
Zinc Administration Favorably Affects Prophylactic Therapy-refractory Migraine Attacks: A Case Series.
Notably, certain nutrients are effective in preventing migraine. Nonetheless, zinc replacement therapy for migraine treatment has yet to be explored. ⋯ Zinc administration may be an option for treating patients with prophylaxis-refractory migraine. Further investigation is required to determine the efficacy of zinc replacement therapy as a treatment option for migraine.

A 69-year-old woman was referred to our hospital because of an acute kidney injury with macroscopic hematuria. She had been taking dabigatran for atrial flutter for six years. Based on the typical histological findings of her kidney biopsy and her history of dabigatran use with prolonged activated partial thromboplastin time, she was diagnosed with dabigatran-related nephropathy complicated by tubulointerstitial nephritis with IgA nephropathy. ⋯ Direct-acting oral anticoagulants, including dabigatran, may cause anticoagulant-related nephropathy similar to warfarin, even in patients with a normal renal function. Tubulointerstitial nephritis may coexist with dabigatran-related nephropathy, and prednisolone therapy should be considered in such cases. IgA nephropathy has been reported as a background disease, and caution should be exercised when encountering it.
