Introduction: Lymphoma is the most common neck mass malignancy in adults but can present diagnostic challenges due to controversy surrounding the best initial biopsy approach. In this study, the authors characterize the diagnostic pathway in adults with lymphoma (or leukemia) presenting initially as a neck mass and examine the biopsy procedures required for diagnosis in a large community-based practice setting.
Methods: Using data from a retrospective cohort of 4103 adults referred to otolaryngology with a neck mass (5% found to be malignant), the authors identified the subset with lymphoma (or leukemia) and examined the time to diagnosis and the number and type of biopsies required for diagnosis.
Rehospitalization for neonatal dehydration: a nested case-control study.
Arch Pediatr Adolesc Med
February 2002
Objectives: To determine the incidence of neonatal dehydration leading to rehospitalization, whether clinical and health services data could predict its occurrence, and the outcome of dehydrated infants.
Methods: We employed a retrospective case-control design nested within a cohort of 51 383 newborns weighing 2000 g or more, with a gestational age of 36 weeks or more born at 11 Kaiser Permanente hospitals during 1995 and 1996. Cases were 110 infants who were rehospitalized within 15 days of discharge with dehydration, and who either had 12% or greater weight loss or a serum sodium level of 150 mEq/L or greater.
