A case report of body stalk anomaly complicating a twin pregnancy.

The body stalk anomaly is described as a maldevelopment during embryonic folding in the third week after conception, resulting in a severe defect of the fetal abdominal wall. The extra-embryonic coelom fails to obliterate and parts of the fetal body remain in an exo-coelomic situation. Reports on its occurrence in multiple pregnancies have in the past focused on concordance between monozygotic twins.

MRI of the pelvic ring joints postpartum: normal and pathological findings.

Purpose: To assess the joints of the pelvic ring postpartum and to discern normal postpartum findings and pathologic lesions using MRI.

Materials And Methods: MR images were obtained in six women with severe pelvic ring pain after delivery, in 13 women after uncomplicated vaginal delivery, and in 11 healthy, nulliparous non-pregnant volunteers. Distances of the pubic gap, signal intensities of the pubic cartilage, and signal changes of the pelvic ring bones were determined and evaluated.

[Oral calcitriol pulse therapy in hemodialysis patients. Effects on histomorphometry of bone in renal hyperparathyroidism].

Background: Hemodialysis patients with symptomatic renal hyperparathyroidism should only get a surgical parathyroidectomy if the oral calcitriol pulse therapy fails. Unfortunately there is no general accepted recommendation for the dosage and intervals of the oral calcitriol pulse therapy.

Patients And Methods: In 34 hemodialysis patients (9 women, 25 men, mean age: 50 +/- 13 years, mean duration time of dialysis: 20 +/- 30 months) with renal hyperparathyroidism (intact parathormon = iPTH > 20 pmol/l) an oral calcitriol pulse therapy was performed over a period of one year.
