Congenital high-airway obstruction syndrome (CHAOS) is due to rare malformations and has been reported previously in only few cases. If the diagnosis can be made prenatally, the ex utero intrapartum treatment (EXIT) procedure may be life-saving. A healthy 28-year old nulli-para was referred because of isolated ascites found at gestational week 16 during routine ultrasound scan. Repeated scans showed overdistended hyperechogenic lungs with inverted diaphragm and a dilated trachea, which was interpreted as a CHAOS resulting from laryngeal atresia. The ascites eventually disappeared. An EXIT procedure was performed at 35 weeks of gestation. Anesthesia of the mother was induced with thiopental, succinylcholine and fentanyl followed by intubation, and maintained with isoflurane and nitrous oxide. A low abdominal midline incision was performed followed by a low transverse incision of the uterus. The fetal head, right arm and shoulder were delivered and intramuscular anesthesia was administered to the fetus. Immediate laryngoscopy confirmed the diagnosis and a tracheostomy was therefore performed. Surfactant was given after a few minutes of ventilation. Compliance improved and when the fetus was easy to ventilate, it was delivered. The baby is developing normally at 18 months of age. Surgical correction of the malformation will be performed after two years of age. It is concluded that some fetuses with a prenatal diagnosis of CHAOS can benefit from the EXIT procedure at delivery. This necessitates a multidisciplinary management team.

The aim of this study was to examine the occurrence of urinary incontinence (UI) in mostly nulliparous women with a history of regular organised trampoline training as adolescents and to identify possible predictors. Female trampolinists in Sweden with licence for trampolining between 1995--1999 (n = 305), with a median age of 21 (range 18-44) years answered retrospectively a validated questionnaire. Competition with double somersaults had been performed by 85 women, the "competition group" (CG), while 220 women comprised the "recreational group" (RG). Of the trampolinists with UI during trampolining, 76% continued to leak. In CG, 57% and, in RG, 48% reported current UI. Strong predictors for UI were inability to interrupt micturition (p < 0.001) and constipation (p = 0.007). Training factors such as frequency/week x years of trampolining (p < 0.001) and years of trampolining after menarche increased the risk of UI (p < 0.001). The prevalence of current UI was higher in ex-trampolinists than in normals (p < 0.001), and hence the negative effects of trampolining cannot be ruled out.

It is concluded that anti-M immunization in a few cases may cause severe fetal hemolytic anemia and intrauterine death. It remains to be elucidated why a normally clinically insignificant antibody is this aggressive in a small proportion of cases. Because the condition is treatable, anti-M must be considered as a possible cause of fetal anemia and intrauterine death.
