[Sepsis due to Salmonella Oranienburg--a case report].

A previously healthy 15-year-old female was admitted to our hospital complaining of nausea and vomiting. She did not complain of diarrhea. A physical examination revealed a lower right quadrant abdominal tenderness without rebound or spontaneous pain and a knocking pain of the costovertebral angle. A high fever, knocking pain of costovertebral angle, and urinary findings including Gram's stain, lead us to suspect a urinary tract infection, cefotiam was administered intravenously. Spiking fever with shaking chills continued for three days, and three sets of blood cultures were positive for Salmonella Oranienburg, but her urine culture was negative. Her history was taken again, revealing an intake of a processed squid product. The product was confirmed by the local public health center to be Salmonella Oranienburg. Finally food poisoning by Salmonella Oranienburg with sepsis was diagnosed. With cefotiam she became better and was discharged from the hospital on the 10th hospital day. During admission to the hospital she did not experience any diarrhea, and her stool culture was negative. Epidemics of Salmonella Oranienburg food poisoning are relatively rare in the literature. In Japan, one has arisen as a result of contamination of a processed squid product in March 1999. However, there have been no cases without so-called gastroenteritic symptoms (abdominal pain and diarrhea) who were previously healthy and developed sepsis caused by Salmonella Oranienburg, reported in Japan. Even in previously healthy patients, with an epidemic situation of non-typhoidal salmonellosis, salmonella sepsis must be ruled out. Among such cases, those who present with spiking fever and shaking chills should be given antibiotic therapy after taking appropriate cultures.

Differences in quantitative EEG between frontotemporal dementia and Alzheimer's disease as revealed by LORETA.

OBJECTIVE: To determine the electrophysiological characteristics of frontotemporal dementia (FTD) and the distinction with Alzheimer's disease (AD). METHODS: We performed analyses of global field power (GFP) which is a measure of whole brain electric field strength, and EEG neuroimaging analyses with sLORETA (standardized low resolution electromagnetic tomography), in the mild stages of FTD (n = 19; mean age = 68.11 ± 7.77) and AD (n = 19; mean age = 69.42 ± 9.57) patients, and normal control (NC) subjects (n = 22; mean age = 66.13 ± 6.02). RESULTS: In the GFP analysis, significant group effects were observed in the delta (1.5-6.0 Hz), alpha1 (8.5-10.0 Hz), and beta1 (12.5-18.0 Hz) bands. In sLORETA analysis, differences in activity were observed in the alpha1 band (NC > FTD) in the orbital frontal and temporal lobe, in the delta band (AD>NC) in widespread areas including the frontal lobe, and in the beta1 band (FTD > AD) in the parietal lobe and sensorimotor area. CONCLUSIONS: Differential patterns of brain regions and EEG frequency bands were observed between the FTD and AD groups in terms of pathological activity. SIGNIFICANCE: FTD and AD patients in the early stages displayed different patterns in the cortical localization of oscillatory activity across different frequency bands.
