Neonatale Hydronephrose : Empfehlungen zur Betreuung in der Welschschweiz

Perinatal asphyxia. Perinatal asphyxia remains one of the most important causes for high mortality and morbidity in the neonatal population. Despite intensive animal and clinical research in this field, no pharmocological strategy has been shown neuroprotective in humans. Moderate hypothermia for severely and moderately asphyctic babies has been aknowledged since a few years as therapeutical approach to improve the outcome of these infants, specifically the long-term follow up (18 months). Neonatal hydronephrosis. Neonatal hydronephrosis is a pathology that requires regular and efficient follow up by a multidisciplinary team. One of the causes of neonatal hydronephrosis is obstructive pathologies which may endanger the kidney. We have developed a strategy that allows a rapid diagnosis of obstructive pathologies with minimal radiological exams. Moreover, this strategy assures the coordination between obstetricians, neonatologists, pediatric urologists, and pediatric nephrologists.

Effects of perinatal stress and maternal traumatic stress on the cortisol regulation of preterm infants.

Preterm infants experience intense stress during the perinatal period because they endure painful and intense medical procedures. Repeated activation of the hypothalamic-pituitary-adrenal (HPA) axis during this period may have long-term effects on subsequent cortisol regulation. A premature delivery may also be intensely stressful for the parents, and they may develop symptoms of posttraumatic stress disorder (PTSD). Usable saliva samples were collected (4 times per day over 2 days, in the morning at awakening, at midday, in the afternoon, and in the evening before going to bed) to assess the diurnal cortisol regulation from 46 preterm infants when the infants were 12 months of corrected age (∼ 14 months after birth). Mothers reported their level of PTSD symptoms. The results showed an interaction between perinatal stress and maternal traumatic stress on the diurnal cortisol slope of preterm infants (R(2) = .32). This suggests that the HPA axis of preterm infants exposed to high perinatal stress may be more sensitive to subsequent environmental stress.

The application of trend surface models to the analysis of time factors in Swiss cancer mortality.

To study different temporal components on cancer mortality (age, period and cohort) methods of graphic representation were applied to Swiss mortality data from 1950 to 1984. Maps using continuous slopes ("contour maps") and based on eight tones of grey according to the absolute distribution of rates were used to represent the surfaces defined by the matrix of various age-specific rates. Further, progressively more complex regression surface equations were defined, on the basis of two independent variables (age/cohort) and a dependent one (each age-specific mortality rate). General patterns of trends in cancer mortality were thus identified, permitting definition of important cohort (e.g., upwards for lung and other tobacco-related neoplasms, or downwards for stomach) or period (e.g., downwards for intestines or thyroid cancers) effects, besides the major underlying age component. For most cancer sites, even the lower order (1st to 3rd) models utilised provided excellent fitting, allowing immediate identification of the residuals (e.g., high or low mortality points) as well as estimates of first-order interactions between the three factors, although the parameters of the main effects remained still undetermined. Thus, the method should be essentially used as summary guide to illustrate and understand the general patterns of age, period and cohort effects in (cancer) mortality, although they cannot conceptually solve the inherent problem of identifiability of the three components.
