Readministration of Pembrolizumab after Treatment of Tuberculosis Activated by Initial Pembrolizumab Therapy.
Increasing the T-cell immune response to Mycobacterium tuberculosis with an anti-programmed cell death 1 (anti-PD-1) antibody may ultimately have detrimental effects. We present the case of a patient with advanced non-small cell lung cancer who developed active tuberculosis (TB) after initial treatment with pembrolizumab, an anti-PD-1 antibody. ⋯ It is sometimes difficult to diagnose CIP using computed tomographic images alone. Careful testing, including bacterial examinations and bronchoscopic biopsy, should be performed.

Development of Severe Acute Pancreatitis Following Uncovered Metallic Stent Placement: A Rare Case Report.
Self-expandable metallic stents (SEMSs) are widely used for malignant biliary stricture (MBS). Acute pancreatitis is an early complication following SEMS placement. ⋯ After seven days, an uncovered SEMS was placed; however, severe acute pancreatitis occurred, and the SEMS was drawn out emergently. In SEMS placement for patients with MBS caused by non-pancreatic cancer, SEMS should be selected carefully while considering each patient's case.

A 48-year-old woman with a 9-year-history of anorexia nervosa (AN) was admitted complaining of generalized bone pain. Blood tests showed hypocalcemia and hyperphosphatasemia, and a radiological survey revealed multiple rib fractures, suggesting complication with osteomalacia. ⋯ Her serum 25-hydroxy vitamin D concentration was below the detectable level. In addition to a poor nutritional intake and insufficient sun exposure, malabsorption of fat-soluble substances in the intestine and phosphate loss from the kidneys might have contributed to the development of her osteomalacia.

A 78-year-old man suspected of having α-synucleinopathies received a high score on a validated questionnaire for rapid eye movement (REM) sleep behavior disorder (RBD). Although he did in fact have unpleasant dreams and vigorous behaviors, polysomnography (PSG) found only obstructive sleep apnea-hypopnea (OSAH). ⋯ Thus, severe OSAH might cause RBD-like symptoms. PSG can discriminate real RBD from RBD-like symptoms associated with severe OSAH and therefore may be essential for determining an appropriate course of treatment in certain patients.

We herein report two patients with early-stage autoimmune gastritis who did not exhibit complete atrophy. Endoscopic examinations showed no manifestations of severe atrophic gastritis, but revealed a mosaic pattern with slight swelling of the areae gastricae restricted to the corpus in both patients. In the patient in case 2, upper gastrointestinal barium X-ray radiography revealed a slightly protruded irregular areae gastricae throughout the gastric body, except for in the antrum. Our findings emphasize the need for clinicians to recognize that autoimmune gastritis might be present in the absence of severe atrophic gastritis; this can aid in the identification of the early stages of autoimmune gastritis.
