Detection of Shigella sonnei in a respiratory specimen in a patient with subacute atypical pneumonia.

Background: Pneumonia caused by shigellosis with or without typical dysentery in immunocompetent patients is an uncommon entity.

Case Report: We describe a case of pneumonia in an immunocompetent, previously healthy middle-aged man from Switzerland without relevant travel history which was presumably caused by Shigella sonnei. He was originally admitted for suspected lung cancer.

Reference curves of symphysis-fundus height in twin pregnancies.

Objective: To generate reliable new reference ranges for symphysis-fundus height (SFH) in twin pregnancies using modern statistical methods and to evaluate whether small-for-gestational age (SGA) babies of women who had a SFH measurement after the 25th gestational week could be predicted by the SFH measurement in the reference curves and other maternal data.

Study Design: In a retrospective cross-sectional study at the obstetric outpatient clinic, Zurich University Hospital, SFH was determined in 257 twin-pregnant women with accurately dateable twin pregnancies (Caucasians: N=217, Asians: N=15, Blacks: N=10, and 15 others). Exclusion criteria were intrauterine fetal death, and known fetal and maternal diseases, which influence SFH.
