ABSTRACT
OBJECTIVES: Clostridioides difficile infection (CDI) burden is not well-characterized in Japan. Therefore, we conducted a population-based, hospitalized CDI incidence study, compared the results with standard-of-care (SOC) CDI testing, and generalized the results for nationwide incidence estimates. METHODS: Surveillance identified inpatients ≥50 years-of-age with diarrhea in nine Tokyo hospitals from December 17, 2018-March 30, 2020. A CDI case was defined as a patient with a PCR-positive/cell cytotoxicity neutralization assay (CCNA)-positive stool or a PCR-positive stool and pseudomembranous colitis (PMC). Incidence estimates were adjusted for the hospitalization share of participating hospitals and, in the sensitivity analysis, for missing CDI test results. SOC specimen collection and CDI testing occurred independently. RESULTS: Surveillance during 318 840 patient-days identified 4633 inpatients with diarrhea. Sixty-three CDI cases were identified; 11 (17·5%) had PMC, eight (12·7%) recurrent CDI, and nine (14·3%) died. The hospitalized CDI incidence was 97/100 000 population per year (PPY) in persons ≥50 years-of-age and, in the sensitivity analysis, 324/100 000 PPY. The incidence was 170 and 481/100 000 PPY in persons ≥65 and ≥85 years-of-age, respectively; these estimates increased to 569 and 1609/100 000 PPY in the sensitivity analysis, respectively. There were 12 primary SOC CDI cases in persons ≥50 years-of-age (18/100 000 PPY). CONCLUSIONS: The CDI incidence was high in older adults, with severe clinical consequences. SOC specimen collection and testing under-estimated CDI burden. There are >57 000 hospitalized CDI cases per year in Japan in persons ≥50 years-of-age. Public health interventions are needed to reduce the CDI burden in Japan.

BACKGROUND: Traumatic aneurysm of the cavernous internal carotid artery (ICA) with extension into the subarachnoid space is associated with increased risk of fatality especially when it is accompanied by severe subarachnoid hemorrhage (SAH). Only cases of patients who survived the acute stage and who were treated in a delayed setting have been reported. There has been no successfully treated case immediately after an injury. CASE DESCRIPTION: We encountered a 48-year-old man who presented with dense SAH immediately after being involved in a motor vehicle accident. Emergent angiography revealed traumatic aneurysm of the left cavernous ICA with extension beyond the superior wall of the cavernous sinus into the subarachnoid space and concomitant direct high-flow carotid cavernous fistula. Detachable platinum coil occlusion of the cavernous ICA followed by superficial temporal artery-middle cerebral artery anastomosis on day 0 and aggressive therapy to SAH, including ventriculocisternal irrigation and drainage, was performed. The patient eventually made a good recovery. CONCLUSION: Considering the extremely poor prognosis and unstable nature of a ruptured traumatic aneurysm with extensive SAH in the acute stage, definitive and immediate prevention of rebleeding in conjunction with proper revascularization would be warranted, such as in the present case.

A 19-year-old woman ingested 2.2 L of "umeshu", a Japanese apricot liquor made with a large amount of sugar. She was unconscious and in shock. The estimated blood ethanol concentration was 607 mg/dl, and the blood glucose level was 576 mg/dl. Because her respiration and circulation was highly suppressed, blood purification was indicated. Continuous hemodiafiltration (CHDF) was performed instead of hemodialysis because her hemodynamics was unstable. After CHDF was instituted, her blood glucose level reduced to normal range, and her consciousness became alert. CHDF was effective in eliminating ethanol and stabilizing her hemodynamics within an early stage. Though acute ethanol intoxication is known to inhibit glucogenesis, leading to hypoglycemia, marked hyperglycemia was seen in this case. Ingestion of a large amount of glucose-rich liquor and being in shock seemed to be the causes of hyperglycemia.
