Case Reports
Recurrent Lymphocytic Hypophysitis Presenting as Internal Carotid Artery Stenosis and Oculomotor Nerve Palsy.
A 75-year-old woman presented with nausea and vomiting. Magnetic resonance imaging (MRI) revealed that she had a pituitary mass. A biopsy revealed lymphocytic hypophysitis (LYH). ⋯ Intravenous methylprednisolone (IVMP) reduced the size of the mass; however, right ophthalmalgia and oculomotor nerve palsy developed. MRI showed that the pituitary mass had enlarged to the right oculomotor nerve in the cavernous sinus and to the right internal carotid artery (ICA), causing stenosis of the ICA. After IVMP administration, the symptoms dramatically improved, but ICA stenosis persisted.

Macitentan Administration for Pulmonary Hypertension Due to β-thalassemia with Multiple Organ Failure: A Case Report.
A 51-year-old Thai woman diagnosed with β-thalassemia underwent regular blood transfusion and iron-chelating therapy. However, after voluntarily discontinuing treatment, the patient developed progressive dyspnea and was diagnosed with pulmonary hypertension following right heart catheterization. ⋯ Despite experiencing hypotension as an adverse event, her condition remained stable during macitentan treatment. Thus, macitentan may be well tolerated in patients with pulmonary hypertension caused by β-thalassemia with multiple organ dysfunction.

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.

Case Reports
Kidney Biopsy Proven Thrombotic Microangiopathy Induced by Methamphetamine: A Case Report.
A 47-year-old man was admitted to our hospital with acute kidney injury, severe hypertension, heart failure, thrombocytopenia, and elevated lactate dehydrogenase. Renal biopsy revealed fibrin thrombi within the glomerular capillaries and moderate fibrotic intimal thickening in the interlobular arteries. ⋯ Blood concentrations of amphetamine and methamphetamine were high (14.1 ng/mL and 333 ng/mL, respectively). It is important to consider methamphetamine as a cause of renal TMA and multi-organ dysfunction.
