Berücksichtigung von „KO-Leistungen“ bei der Bestimmung des Individualbudgets hausärztlicher Leistungserbringer

Abstrakt Bei der Bestimmung des Individualbudgets eines haus?rztlich t?tigen Vertragsarztes sind auch von diesem im Bemessungszeitraum zul?ssig erbrachte sog. „KO-Leistungen“ zu berücksichtigen. Es ist irrelevant, wenn diese Leistungen nach Ende des Bemessungszeitraums vom Leistungserbringer nicht mehr abgerechnet werden dürfen. (Leitsatz des Bearbeiters)     

The choriocapillaris in spontaneously diabetic rats.

During diabetes in rats, the choroid of the eye shows increased permeability to albumin, basement membrane thickening, and decreased anionic charge sites on the abluminal surfaces of the choriocapillary microvessels. In other microvascular beds, permeability differences are correlated with differences in luminal membrane microdomains as indicated by the distribution of luminal membrane anionic charge. To see whether luminal surface charge distribution or other structural features of the choroidal microvasculature become altered during diabetes, we studied spontaneously diabetic and control rats using ultrastructural tracers and morphometric techniques. Rats were injected with horseradish peroxidase and perfused with aldehydes, and then retina-choroid tissue sections were incubated with cationized ferritin, reacted to visualize peroxidase, and prepared for electron microscopic study. The most striking alterations in the diabetic rats were vascular debris and migrating cells resembling vascular cells in the choriocapillaris stroma, suggesting an increase in capillary turnover. In addition, extracellular matrix material was increased, and peroxidase uptake and ferritin binding were low in some vessels of the diabetic rats compared with the controls. Variability was large in the diabetic animals, however, and other vessels remained apparently normal.     

Azygoesophageal recess: normal CT appearance in children.

The azygoesophageal recess is the interface of the subcarinal portion of the mediastinum and the right lower lobe. The configuration of the recess on CT can be used as a sensitive indicator of abnormality in the mediastinum. In normal adults the recess is concave. A convex contour is a normal variant, particularly in young adults. The normal appearance of the azygoesophageal recess in children has not been studied. Accordingly, we reviewed chest CT examinations performed in 253 children ranging from 1 month to 20 years old. Forty patients were excluded from further analysis either because the recess could not be evaluated properly or because underlying disease caused the mediastinum to have an abnormal configuration. An age-related spectrum of normal configurations was observed in the remaining 213 patients. A convex or straight contour was found in 96% of children less than 3 years old. Scans of children 3-12 years old revealed a spectrum of configurations. The typical adult concave configuration was seen in 78% of adolescents more than 12 years old. Overall, in only 90 (42%) of 213 children in this study was a concave recess observed on CT. Our experience shows a convex azygoesophageal recess on CT should be considered the normal configuration in infants and young children. Recognition of this age-related variation is useful in the CT evaluation of the mediastinum in children.     

Corrosive injury of the oesophagus in childhood

A 10-year retrospective review of 73 children who had ingested a corrosive agent was performed. Presentation, management, and eventual outcome were assessed, and comparisons were made between those who received early medical treatment and those who did not. Results suggested that immediate proper assessment of the oesophagus and institution of appropriate therapy may reduce the incidence of complications associated with treatment of subsequent stricture formation. The importance of oesophagoscopy in the direct visualization of the oesophagus within 24-48 h of the burn is stressed.     

Psychosocial factors, curative therapies, and behavioral outcomes. A comparison of testis cancer survivors and a control group of healthy men

In a retrospective study of 223 testis cancer survivors and 120 controls matched sociodemographically, we examined the relative impact of sociodemographic and clinical factors on long-term outcomes in the areas of sexual function, relationships, employment, and mental outlook. For most of the survivors, testis cancer did not lead to unemployment (4.5%), divorce (6.8%), or disabling psychological problems. Multivariate analysis results confirm that cancer survivors report significantly more infertility and sexual performance distress, but not more desire distress, than the control group. Survivors' sexual impairment varied according to treatment received (and therefore histologic factors) and sociodemographic variables. Parental status (not having children) and education (college or less) independently predict infertility distress, whereas education and lower occupational level independently predicted sexual performance distress. Adjusting for socioeconomic status (SES), the men with advanced testis cancer who received chemotherapy and standard retroperitoneal lymph node dissection (RPLND) had significantly more infertility and performance distress than those men who received other treatments. Neither the treatment or SES variables predicted disrupted relationships or a deteriorated mental outlook. However, men with sexual impairment distress were more likely to report strained relationships and a pessimistic mental outlook. These findings have implications for treatment decisions and can be used to identify subgroups of survivors who could benefit from counseling and sexual rehabilitation services.     

Obstructive jaundice. An unusual delayed presentation of congenital diaphragmatic hernia

Most cases of congenital diaphragmatic hernia present as acute respiratory emergencies in the newborn period. Delayed presentation may be heralded by symptoms referred to the respiratory or gastrointestinal tract. An infant with unrecognized right-sided foramen of Bochdalek hernia presented with obstructive jaundice due to compression of the herniated common bile duct by the rim of the diaphragmatic defect. To our knowledge, this occurrence has not been previously observed in infancy or childhood.
