ABSTRACT: Matters of hospital management do not figure prominently on the medical ethics agenda. However, management decisions that have to be taken in the area of hospital care are in fact riddled with ethical questions and do have significant impact on patients, staff members, and the community being served. In this decision making process evidence based medicine (EBM) plays an increasingly important role as a tool for rationalising as well as rationing health care resources. In this article, ethical issues of hospital management and the role of EBM will be explored, with particular reference to disease management programs, diagnosis related groups, and clinical pathways as recent developments in the German health care system.

ABSTRACT: Staphylococcal scaled-skin syndrome (SSSS) is a toxin-related epidermolytic disease that usually affects infants and children under 5 years. We report herein a case of a premature infant who had developed SSSS after an infection of the pharynx with staphylococci and who died of septicaemia due to pseudomonas aeruginosa. The primary mechanism of action of epidermolysin still remains unknown. We demonstrate that acantholysis is due to an early edema of the intercellular space with separation of ultrastructurally unaltered desmosomes.

ABSTRACT: Recent studies have shown that in boys a steady-state of blood lactate is maintained at exercise levels above the anaerobic threshold. Therefore, the explanation hitherto provided for the steeper increase in blood lactate beyond the anaerobic threshold, i.e. the onset of anaerobic metabolism, needs modification. Investigations were carried out in ten boys, aged 11-12 years, during treadmill running. Maximal oxygen uptake (VO2max) and maximal blood lactate were determined during incremental exercise. Subsequently each boy performed four runs at different high constant speeds of 16 min duration, in order to determine maximal steady-state blood lactate. The underlying data also served to estimate roughly the lactate anaerobic threshold. Oxygen uptaken (VO2) was measured at 0.5 min intervals during the initial 7.5 min of each constant-speed run. Maximal steady-state blood lactate was 5.6 mmol/l corresponding to 92% of VO2max. The mean blood lactate at which the anaerobic threshold was reached or just exceeded was 2.7 mmol/l corresponding to 82% of VO2max. Oxygen transport transient kinetics were computed from the mean 0.5 min VO2-values during the constant-speed runs near the maximal steady-state blood lactate and from runs near the anaerobic threshold. Half-times of VO2 response were shorter than values previously reported for adults due to a faster increase in VO2 at the onset of exercise. Half-times increased with increasing work rates as did the oxygen deficit, due to a slower increase in VO2 along with a longer time required to attain a steady-state at higher work rates.(ABSTRACT TRUNCATED AT 250 WORDS)

ABSTRACT: Restrictive dermopathy is a recently described lethal congenital disorder of the skin with an autosomal recessive mode of inheritance. The rigidity of the skin impairs fetal movements in utero and causes arthrogryposis, as well as highly characteristic facial features and pulmonary hypoplasia. We report two cases of restrictive dermopathy in prematurely born infants, describe the typical pathological findings and discuss this disorder in the context of the fetal akinesia/hypokinesia deformation sequence.

ABSTRACT: The frequencies of HLA A, B, C and DR antigens were evaluated in 220 persons from West Germany with inapparent and manifest Borrelia burgdorferi infections. Thirty-seven forest workers showing elevated antibody titres against Borrelia burgdorferi had asymptomatic infection, and are described as stage 0. One hundred and eighty-three patients presented with the clinical stages 1-3 of the infection. Control persons (n = 655) were typed in the same time period and by identical staff. HLA CW3 was present in 36.3% of patients as compared to 23.2% of the controls (RR = 1.88, pcorr = 0.03) and was significantly associated with manifest infection. In addition, the antigen A2 was found slightly but not significantly more frequent in the patients (55.2% vs 44%; pcorr = 0.41). The phenotype combination HLA A2 and Cw3, however, was significantly elevated in patients (24.6% vs 10.8%; pcorr = 0.0005). In contrast to these class 1 antigens, HLA DR3 showed a tendency of negative association with manifest infection. But this finding was not yet found to be significant (15.3% vs 25.3%; RR = 0.53, pcorr = 0.26). The frequency of HLA DR2 showed a constant decrease from stage 0 to stage 3 (inapparent infection to late complications). Using the rank correlation coefficient of Spearman, this association was found to be significant (-1.00, p less than or equal to 0.05). All other tested HLA antigens and antigen combinations showed no significant differences. The data suggest that HLA CW3 may be associated with Borrelia burgdorferi infection, whereas HLA DR2 and DR3 may be associated with less incidence of severe courses and less complications in this disorder.

ABSTRACT: Micromolecular proteins (molecular weight less than 68 kD) in amniotic fluid are assumed to be derived largely from fetal urinary excretion and therefore may reflect fetal kidney function and maturation. Microprotein concentrations in amniotic fluid, neonatal urine and urine of fetuses with bilateral urinary tract dilation were analyzed using microgradient gel electrophoresis to separate proteins according to their molecular size. Alpha-1-microglobulin and beta 2-microglobulin were assayed as singular micromolecular marker proteins. Microproteins in amniotic fluid decreased progressively with advancing gestation during the 3rd trimester. Micromolecular protein concentrations in the first postnatal urine of healthy infants born prematurely or at term were similar to those in amniotic fluid of corresponding fetal age and yielded an identical developmental pattern. A strong correlation existed between the microprotein concentrations in amniotic fluid and fetal urine. It is concluded that fetal urinary production is the main determinant for the microprotein content of amniotic fluid and that a major fetal pathway exists for the intrauterine metabolism of these proteins. The 3rd trimester decrease in amniotic fluid seems to be dependent on the increasing reabsorption capacity of proximal tubular cells representing morphological and functional kidney maturation. The exact diagnostic value of microprotein analysis for the assessment of disturbed fetal kidney function has still to be defined by further investigation.

ABSTRACT: Thrombin (Thr), plasmin (Pl) and elastase (ELP) are serine proteinases which are quickly inactivated by their specific inhibitors (AT III, alpha 2AP, alpha 1AT), if intravascular activation of coagulation and fibrinolytic system or if release from PMN granulocytes by different stimuli (F.I., endotoxin, activated factor XII, a.o.) occurs. The immunological determination of the developing proteinase inhibitor complexes (PIC) AT III-Thr, alpha 2AP-Pl and alpha 1AT-ELP gives information as to whether intravascular coagulation, hyperfibrinolysis or unspecific proteolysis induced by elastase have taken place. Despite the high antiprotease activity in the plasma the a.m. serine proteinases may exert their proteolytic activity towards their specific substrates in vivo. In infectious diseases, fulminant hepatic failure and cardiac shock a complex consumption of coagulation factors and inhibitors may cause severe coagulation defects, microcirculatory disturbances and bleeding tendency. The PICs behaviour was determined in more than 80 patients with infectious diseases, in 5 patients with fulminant hepatic failure (FHF) and 7 patients with cardiac shock. Only in infectious diseases, mainly in septic complications, and septic complications during FHF and cardiac shock, are alpha 1AT-ELP levels found to be highly elevated. After cardiac shock, in FHF and in infectious diseases coagulation and fibrinolysis may additionally be activated. In this case AT III-Thr and alpha 2AP-Pl complexes could be detected in the patients plasma. This indicates that intravascular coagulation and hyperfibrinolysis has additionally taken place. To prevent bleeding complications a replacement therapy with plasma derivatives (AT III, plasminogen concentrate, PPSB and FFP) has been successfully performed in several patients with septic complications and in the 5 patients with FHF and the 7 patients with cardiac shock. No bleeding complication occurred, and the haemostatic balance could be maintained in the treated patients. AT III replacement therapy is necessary to stop DIC, PPSB improves severe coagulation defects, only FFP may additionally provide alpha 1AT, alpha 2AP and factor V. In acute renal failure sometimes plasminogen replacement is necessary to maintain a normal activity of the fibrinolytic system. The complex consumption of coagulation proteins in infectious diseases, FHF and cardiac shock cannot successfully be treated with an anticoagulant such as heparin alone.

ABSTRACT: 108 adolescents with type 1 diabetes as well as their parents and physicians in charge were studied in a prospective longitudinal design. Most of the juvenile patients were of good metabolic control. The results from different questionnaires of coping are presented. The opinions of the patients, their parents and the physicians in charge differ in some important aspects. Furthermore there are significant differences between the patients of best versus worst metabolic control as far as the extent of self reported psychosocial problems related with the disease is concerned.
