Abstract
Introduction : The purpose of this study was to identify the function of outpatients' explanatory models by qualitative research.
Methods : Medical records of ninety one patients from our department were investigated from 1st September 2011 to 28th February 2012 inclusive, and were analyzed by the modified grounded theory approach.
Results : The explanatory models were categorized into three groups according to their narrative, which included the following : Diagnostic model, Pathological model and Psycho-social model. Patients in the psycho-social model had no organic diseases except one pneumonia case. In the other two models, one half of the patients had organic diseases. However, the patients' self-diagnoses were frequently incorrect. We considered that their diagnostically incorrect narratives contained potential hidden messages. We therefore generated an hypothesis that patients projected their cognitive images onto the diseases they suspected.
Conclusion : We consider that a patient's self-diagnosis, such as cancer or cerebral infarction, appears to contain both medical information and a metaphorical message. Further investigation is needed to understand the meaning of such hidden messages.

Background: Urosepsis is a potentially fatal syndrome that is sometimes difficult to diagnose. Thus, the aim of the present study was to clarify the clinical and laboratory characteristics and pitfalls in the diagnosis of urosepsis.
Methods: We enrolled the study participants based on clinical records of patients with urosepsis treated between January 2009 and April 2012 inclusive, in the Department of General Internal Medicine, Toyama University Hospital and retrospectively surveyed underlying diseases, clinical symptoms, physical findings, and laboratory data, respectively.
Results: Ten definitive patients were selected (nine females and one male; age, 55–86 years). Fever was the most frequent symptom followed by nausea. Lower back pain was the chief complaint in only two patients. One patient complained of dysuria, and on examination half of the patients lacked costovertebral angle (CVA) tenderness. Five patients showed elevated liver enzymes without evidence of hyperbilirubinemia.
Conclusions: There were no specific clinical characteristics of urosepsis, and symptoms in some patients resembled digestive diseases such as cholangitis. Our results demonstrate that use of dipstick urinalysis and microscopic urinalysis are essential for the diagnosis in patients with sepsis. Abdominal ultrasonography and/or computed tomography should also be considered to rule out false negative results of urinalysis related to urinary tract obstruction, and to detect other focal infections when appropriate.
