In the last decade, methicillin-resistant Staphylococcus aureus (MRSA) has been identified in livestock animals, such as swine, poultry, and veal calves, and has been termed livestock-associated MRSA (LA-MRSA). LA-MRSA sequence type (ST) 398 strains can effectively infect and colonize humans, with subsequent human-to-human transmission in both community and hospital settings. Unlike other countries, LA-MRSA had not been reported in Japanese patients until 2019. However, we recently reported a case of intractable arthritis caused by an LA-MRSA CC398 (ST1232) clone, which is a single-locus variant of ST398, in a patient in Tokyo, Japan, with no animal contact (Nakaminami H, et al. Emerg Infect Dis. 2020; 26: 795-7.). Uniquely, the strain was positive for Panton-Valentine leukocidin. Here, we report the second such case in Japan. To prevent the dissemination of LA-MRSA in the Japanese community, the prevalence of the CC398 MRSA clone should be closely monitored in the future.

An 81-year-old man was admitted to our hospital because of general fatigue. Hormonal examination showed that he had panhypopituitarism and central diabetes insipidus. MRI imaging revealed the presence of large cystic mass with suprasellar extension in his hypothalamo-pituitary region. Interestingly, the cystic mass shrank following the start of glucocorticoid replacement, and since then relatively high doses of cortisol administration were needed to prevent the re-enlargement of cystic size. Because of the concern over possible side effects of supraphysiological doses of glucocorticoid replacement, surgical treatment was eventually carried out, confirming the pathological feature of Rathke's cleft cyst. The present case suggests that the inflammatory nature of Rathke's cleft cyst may explain the observed short-term size changes in response to glucocorticoid administration.

We describe a patient in whom a fish bone penetrated the duodenum and migrated into the right renal vein. The bone was successfully removed with surgery. The 75-year-old man was admitted to Nippon Medical School Tama Nagayama Hospital because of right upper abdominal pain persisting for 7 days. The patient's medical history was not relevant to the current disorder. Plain radiography showed no abnormalities. Computed tomography revealed a linear object of high intensity that had penetrated the duodenum and migrated into the right renal vein with thrombus. The object was surrounded by a low-density area, suggesting severe inflammation. The patient had eaten fish 1 day before the onset of abdominal pain. We diagnosed duodenal penetration caused by an ingested fish bone. Endoscopic examination showed erosion, but no fish bone or ulceration was detected in the duodenum. The patient was treated conservatively with fasting, peripheral parental nutrition, and intravenous antibiotics. Three days after admission, non-contrast-enhanced computed tomography showed no movement of the foreign body. The patient continued to have pain, and the decision was made to surgically explore the abdomen. Intraoperative ultrasonography showed that the foreign body had migrated completely into the right renal vein with thrombus. Severe inflammation of the right renal vein was observed. Because we could not remove the foreign body without seriously injuring the right renal vein, right nephrectomy was performed. Macroscopic examination of the surgical specimen confirmed the presence of a fish bone with thrombus in the right renal vein. The patient was discharged 9 days after operation, with no complications.
