Exploring the risk factors for vaccine-associated and non-vaccine associated febrile seizures in a large pediatric cohort.

Introduction: It is not known whether there are underlying physiologic or immunologic differences between febrile seizures (FS) triggered by vaccines versus other causes. Furthermore, while secular and individual-level factors have been associated with FS risk, they are rarely evaluated simultaneously.

Methods: Subjects included members of Kaiser Permanente Southern California aged 6 months to 3 years from July 1, 2003-December 31, 2011.

Results of computed tomography in family practitioners' patients with non-acute abdominal pain.

Objectives: The utility of abdominal computerized tomography (CT) for evaluating abdominal pain in non-emergency, primary care outpatients is unknown. Family practice patients commonly report abdominal pain.

Methods: We reviewed the records of health maintenance organization primary care outpatients <2 years after they had undergone CT for abdominal pain and assessed demographic variables, clinical and laboratory data, CT findings and final diagnoses.

Chronic abdominal wall pain: clinical features, health care costs, and long-term outcome.

Background & Aims: Chronic abdominal wall pain (CAWP) often is misdiagnosed. We evaluated CAWP patients regarding diagnosis accuracy, clinical features, comorbidity, referral frequency, use of care, and long-term outcome.

Methods: We reviewed the records of all outpatients referred to a gastroenterologist in 5 years, recorded referral indications, and identified patients initially diagnosed with CAWP or irritable bowel syndrome (IBS).
