Remission of Angiographically Confirmed Minocycline-induced Renal Polyarteritis Nodosa: A Case Report and Literature Review.
A 23-year-old man presented with severe hypertension. Based on his history of minocycline treatment for over three years and clinical symptoms, such as myalgias and renovascular hypertension with multiple intrarenal aneurysms, he was diagnosed with minocycline-induced renal polyarteritis nodosa (PAN). ⋯ Seven and a half years later, repeated angiography found that the aneurysms had resolved. This is the first report in English describing a case of minocycline-induced renal PAN that was reversed functionally and morphologically without steroids or immunosuppressive drugs.

Review Case Reports
Onset of Aortic Dissection Complicated with Cushing's Disease: A Case Report and Review of the Literature.
Cushing's syndrome and Cushing's disease cause various metabolic disorders associated with high cortisol levels. Some reports have shown that Cushing's syndrome is complicated with dissecting aortic aneurysm and aortic dissection after long-term exposure to high cortisol levels. ⋯ Aortic dissection may occur even under relatively short periods of high cortisol conditions. This case suggests that hypercortisolemia should be treated as soon as possible in order to prevent aortic dissection in subjects with Cushing's disease.

Imported African Tick Bite Fever in Japan: A Literature Review and Report of Three Cases.
African tick bite fever (ATBF) is an acute febrile illness caused by Rickettsia africae. ATBF is an important differential diagnosis of acute febrile illness among returned travelers. However, little information is available on ATBF cases imported to Japan, as only seven have been reported to date. To characterize the epidemiological and clinical profiles of patients diagnosed with ATBF in Japan, we reported three new ATBF cases at our hospital between May 2015 and April 2018 and conducted a literature review.

A 65-year-old man experienced cough and shortness of breath 3 days after receiving the first dose of the Pfizer-BioNTech coronavirus disease 2019 (COVID-19) vaccine. Chest X-ray revealed bilateral infiltrates, and the desaturation deteriorated rapidly. ⋯ Based on these findings, the patient was diagnosed with COVID-19 vaccine-induced pneumonitis. The timing of the onset of pneumonitis after vaccination and the results of intradermal testing suggest that Type IV hypersensitivity against COVID-19 vaccine may have been responsible for this clinical condition.
