Dimensions of anger-hostility and cardiovascular reactivity in provoked and angered men.

This study investigated the relationship between two dimensions of anger-hostility--the expression of anger-hostility and the experience of anger-hostility--and cardiovascular reactivity in provoked and angered men. A serial subtraction task was administered to 41 male undergraduates who were provoked and angered. A measure of the expression of anger-hostility correlated positively and significantly with systolic and diastolic blood pressure (BP) reactivity. There were no significant correlations between a measure of the experience of anger-hostility and cardiovascular reactivity. The two types of anger-hostility were also found to relate differentially to life-style variables that have been identified as risk factors for coronary heart disease (CHD), with only the expression of anger-hostility showing positive relationships with these life-style CHD risk factors. These findings are discussed within the context of a similar differential relationship between the two dimensions of anger-hostility and CAD and CHD. Finally, significant negative relationships were obtained between the experience of anger-hostility and resting BP and heart rate levels. These findings are discussed within the context of other data suggesting that trait anxiety-neuroticism may have protective properties.

Robinow syndrome with parental consanguinity.

We describe the clinical features of Robinow syndrome in the first child of a consanguineous Turkish couple. This observation supports the view that severe vertebral anomalies are a feature of the autosomal-recessive form of Robinow syndrome.

Further linkage data on cystic fibrosis: the Utah Study.

We reported earlier complete linkage between cystic fibrosis and an RFLP of the met proto-oncogene revealed by the probe pmetH. Another clone, pmetD, detects another polymorphism with the TaqI restriction enzyme. Further linkage studies, now involving 22 families, have confirmed the tight linkage of cystic fibrosis to the MET and D7S8 loci. Significant allelic association was found between CF and allelic series defined by the pmetH probe.

Focal and diffuse liver disease studied by quantitative microstructural sonography.

Quantitative microstructural sonography differs from conventional sonography in several ways. The frequency as well as the amplitude of echoes is recorded and assessed using spectral analysis techniques. The effects of diffraction of the ultrasound beam are calibrated, as are the transfer characteristics of the system. Studies of patients with alcoholic liver disease revealed significantly increased attenuation, heterogeneity of scatterers, and local scattering strength in those with severe disease; in contrast, patients with mild cirrhosis exhibited decreased local scattering strength compared to normal individuals. Using retrospective three-parameter discriminant analysis, 23 out of 24 patients were successfully categorized, suggesting that the parameters used were capable of measuring microstructural changes associated with these disease states. Parameters varied widely among 6 types of hepatic tumors, suggesting that this method may offer promise in distinguishing tumors from normal cases and alcoholic liver disease as well as from each other. Further applications and evaluation of this method appear justified.

[Clinical picture in patients with 46,X,i(Xq) karyotype. Are there differences from Turner syndrome?].

Clinical presentation in 2 patients with 46,X,i(Xq)-Karyotype are described. In both cases no mosaicism could be detected. The two patients show the classical features of gonadal dysgenesis: short stature, sexual infantilism and primary amenorrhea due to streak ovaries. Other characteristic somatic manifestations of the Turner syndrome such as webbing of the neck, however, were missing. In one of the two cases a Hashimoto's thyroiditis was present, which has been repeatedly reported before in the literature in cases with 46,X,i(Xq)-karyotype.

Solitary rectal ulcer progressing to pseudo-cloaca: a case report.

A 57 year old diabetic patient is reported with the progression of a solitary ulcer of the anterior rectal wall which resulted in destruction of the posterior bladder wall, and subsequent pseudocloaca. The patient was successfully treated by colonic and urinary diversion. The etiology of this condition remains obscure. A review of the literature on this uncommon lesion is discussed.

[The evaluation of cortisol in amniotic fluid and in maternal blood as parameter for foetal lung maturity (author's transl)].

The lecithin/sphingomyelin-ratio (L/S-ratio) in amniotic fluid has become established in recent years as a valuable laboratory parameter for determining foetal lung maturity and has thus helped to avoid the neonatal respiratory distress syndrome. Since glucocorticosteroids are a decisive factor in stimulating foetal lung development, we were prompted to investigate whether the determination of cortisol in amniotic fluid or maternal blood could also serve as an indicator of foetal lung maturity. The cortisol concentration was measured by radioimmunoassay in amniotic fluid (n = 91) and in maternal venous plasma (n = 70) from normal and complicated pregnancies and was compared with the L/S-ratio. A significant correlation between gestational age and cortisol in amniotic fluid (r = 0.711) and in maternal venous plasma (r = 0.625) was observed. There was also a significant correlation between the L/S-ratio and amniotic fluid cortisol (r = 0.701). However, compared to the L/S-ratio, measurements of cortisol yielded 10% false positive and 11% false negative results. A significant correlation between the L/S-ratio and the maternal plasma cortisol could also be demonstrated (r = 0.631). Here the comparison with the L/S-ratio gave even poorer results: 16% false positive and 6% false negative. The high percentage of false results, especially false positive results yielded by cortisol estimations in both fluids leads to the conclusion that the L/S-ratio remains the superior diagnostic parameter in determining foetal lung maturity.
