[Hemorrhagic Onset of Subependymal Giant Cell Astrocytoma Associated with Tuberous Sclerosis:A Case Report and Review of Literature].

We report on a case of subependymal giant cell astrocytoma(SEGA)in a patient with tuberous sclerosis(TSC)that presented with intratumoral hemorrhage and acute hydrocephalus. Initial treatment was external ventricular drainage to control the intracranial pressure;however, the tumor increased in size due to recurrent hemorrhage. Subsequently, the tumor was successfully removed via the transcortical-transventricular approach without neurological deterioration.

Chronological change of antibiotic use and antibiotic resistance in Escherichia coli causing urinary tract infections.

Overuse of antibiotics can cause the emergence of resistant bacterial strains. This study retrospectively investigated recent trends in Escherichia coli causing urinary tract infections (UTIs), focusing on antibiotic use and antibiotic susceptibilities. Patients diagnosed with UTIs caused by E.

[Comparison of detection sensitivity in rapid-diagnosis influenza virus kits].

Rapid-diagnosis kits able to detect influenza A and B virus by immunochromatography developed by different manufacturers, while useful in early diagnosis, may vary widely in detection sensitivity. We compared sensitivity results for eight virus-detection kits in current use--Quick Chaser FluA, B (Mizuho Medy), Espline Influenza A & B-N (Fujirebio), Capilia Flu A + B (Nippon Beckton Dickinson & Alfesa Pharma), Poctem Influenza A/B (Otsuka Pharma & Sysmex), BD Flu Examan (Nippon Beckton Dickinson), Quick Ex-Flu "Seiken" (Denka Seiken), Quick Vue Rapid SP Influ (DP Pharma Biomedical), and Rapid Testa FLU stick (Daiichi Pure Chemicals)--against influenza virus stocks, contained five vaccination strains (one A/H1N1, two A/H3N2, and two B) and six clinical strains (two A/H1N1, two A/H3N2, and two B). Minimum detection concentrations giving immunologically positive signals in serial dilution and RNA copies in positive dilution in real-time reverse transcriptase-polymerase chain reaction (RT-PCR) were assayed for all kits and virus stock combinations.
