A 27‐year‐old woman with panic disorder taking 20 mg olanzapine daily for 4 months was admitted to Mito Kyodo General Hospital, Mito, Ibaraki, Japan, because of disturbed consciousness with fever, hyperglycemia, hyperosmolarity and elevated creatine phosphokinase. She was diagnosed with a hyperosmolar hyperglycemic state and neuroleptic malignant syndrome. Brain magnetic resonance imaging showed transiently restricted diffusion in the splenium of the corpus callosum, with a high signal intensity on diffusion‐weighted imaging. The neurological abnormalities disappeared along with improvement of metabolic derangements, and the follow‐up magnetic resonance imaging carried out on the 26th day of admission showed complete resolution of the lesions in the splenium of the corpus callosum. These clinical and radiological features are highly suggestive of clinically mild encephalitis/encephalopathy with a reversible splenial lesion. The first case of mild encephalitis/encephalopathy with a reversible splenial lesion caused by olanzapine‐induced hyperosmolar hyperglycemic state and neuroleptic malignant syndrome is reported.

Aims/Introduction Flash and continuous glucose monitoring systems are becoming prevalent in clinical practice. We directly compared a flash glucose monitoring system (FreeStyle Libre Pro [FSL ‐Pro]) with a continuous glucose monitoring system ( iP ro2) in patients with diabetes mellitus. Materials and Methods Glucose concentrations were simultaneously measured using the FSL ‐Pro, iP ro2 and self‐monitoring blood glucose in 10 patients with diabetes mellitus, and agreement among them was assessed. Results Parkes error grid analysis showed that the 92.9 and 7.1% of glucose values measured using the FSL ‐Pro fell into areas A and B, respectively, and that 96.3, 2.8 and 0.9% of those determined using iP ro2 fell into areas A, B and C, respectively. The median absolute relative differences compared with self‐monitoring blood glucose were 8.1% (3.9–12.7%) and 5.0% (2.6–9.1%) for the FSL ‐Pro and iP ro2, respectively. Analysis of 5,555 paired values showed a close correlation between FSL ‐Pro and iP ro2 glucose values (ρ = 0.96, P < 0.01). Notably, 65.3% of all glucose values were lower for the FSL ‐Pro than the iP ro2. Median glucose values also decreased by 3.3% for the FSL ‐Pro compared with the iP ro2 (177.0 [133.0–228.0] vs 183.0 [145.0–230.0] mg/dL, P < 0.01). The difference in glucose values between the two systems was more pronounced in hypoglycemia. The median absolute relative difference between FSL ‐Pro and iP ro2 during hypoglycemia was much larger than that during euglycemia and hyperglycemia. Conclusions Both the FSL ‐Pro and iP ro2 systems are clinically acceptable, but glucose values tended to be lower when measured using the FSL ‐Pro than the iP ro2. Agreement was not close between these systems during hypoglycemia.

Haemophilus species are known to colonize the upper respiratory tract and can cause infections. However Haemophilus influenzae has been rarely described as a cause of genitourinary tract infection. We report a 44-year-old nonimmunocompromised Japanese man with bacteremic pyelonephritis caused by a nontypable H. influenzae associated with a left ureteral calculus. The organism was isolated from both blood and urine cultures. Treatment consisted of 14 days of intravenous ceftriaxone and oral amoxicillin one after than other and insertion of a left ureteral stent. After discharge, he underwent extracorporeal shock wave lithotrity for the left ureteral calculus. He had no recrudescence of the symptoms. H. influenzae should be considered as a genitourinary pathogen among patients with certain risk factors such as anatomical or functional abnormality of genitourinary tract. Collaboration between clinicians and microbiology laboratory personnel is essential for correct identification of the organism and appropriate therapy for genitourinary tract infections due to this organism.

Aims/Introduction The importance of low‐density lipoprotein cholesterol (LDL‐C) in the primary prevention of cardiovascular disease has recently been reported in the population aged ≥75 years with hypercholesterolemia. Therefore, the current status of LDL‐C management for primary prevention of coronary artery disease in patients aged ≥75 years with type 2 diabetes mellitus was investigated. Materials and Methods A total of 124 patients aged ≥75 years who had type 2 diabetes mellitus, but no coronary artery disease, were investigated. The patients' background characteristics, LDL‐C, glycemic status, ankle‐brachial index and cardio‐ankle vascular index were compared between patients taking and not taking LDL‐C‐lowering agents, such as hydroxymethylglutaryl‐CoA reductase inhibitors (statins) and ezetimibe. The details of the antihyperlipidemic and antidiabetic agents used in the present study were also examined. Results LDL‐C was significantly lower in patients taking LDL‐C‐lowering agents (LDLCLT[+]) than in patients not taking them (LDLCLT[−]), although LDL‐C was maintained <120 mg/dL in both groups (93.0 mg/dL vs 102.1 mg/dL). Approximately half of the cases in the LDLCLT(+) group received moderate‐intensity statins, with pitavastatin being the most prescribed statin. Glycated hemoglobin was significantly lower in the LDLCLT(+) group than in the LDLCLT(−) group (6.9% vs 7.3%). Sodium‐glucose transporter 2 inhibitors were more frequently used in the LDLCLT(+) group than in the LDLCLT(−) group. The ankle‐brachial index/cardio‐ankle vascular index did not differ between the groups. Conclusion Low‐density lipoprotein cholesterol was properly managed for primary prevention of coronary artery disease in patients aged ≥75 years with type 2 diabetes mellitus regardless of the presence or absence of LDL‐C‐lowering agents.
