Prognostic Factors for Niche Development in the Uterine Caesarean Section Scar.

In a prospective study on 134 women after their first cesarean section prognostic factors for developing an uterine niche (scar defect) measured with sonohysterography were evaluated. With multivariable logistic regression anlaysis the following prognostic factors were identified; enlarged cervical dilatation and induction of labour. Contractions before labour reduced the risk for niche development.

Intussusception presenting with malignant hypertension and lethargy.

The most common cause of malignant hypertension in children is renal or renovascular pathology. The combination with lethargy suggests a diagnosis of hypertensive crisis with hypertensive encephalopathy. Here, we present a case of severe hypertension with lethargy as the sole presenting symptoms of ileocecal intussusception.

Therapeutic options of caesarean scar pregnancy: case series and literature review.

We describe our experience with the treatment of 4 caesarean scar pregnancies and provide an overview of current literature. Four women diagnosed with a caesarean scar pregnancy in our hospital between 1996 and 2007 were treated with local or systemic methotrexate and had a steady decline of the serum beta-hCG level. The uterus was preserved in all women and 3 of them had an uneventful subsequent pregnancy and delivery.

Principles behind the multifarious control of signal transduction. ERK phosphorylation and kinase/phosphatase control.

General and simple principles are identified that govern signal transduction. The effects of kinase and phosphatase inhibition on a MAP kinase pathway are first examined in silico. Quantitative measures for the control of signal amplitude, duration and integral strength are introduced.
