[Demonstration of a species specific determinant of Bacteroides fragilis lipopolysaccharides using monoclonal antibodies].

The reactivity of two monoclonal antibodies to Bacteroides fragilis was tested (ELISA) with 37 strains of B. fragilis, 1 strain each of B. thetaiotaomicron, B. ovatus, B. vulgatus and B. eggerthii, 1 strain of Fusobacterium, as well as Pseudomonas aeruginosa (6 strains), E coli (8 strains), Klebsiella (2 strains), Yersinia enterocolitica (1 strain) and LPS from Salmonella minnesota. Both monoclonal antibodies proved to be specific for B. fragilis. The determinants recognized by these antibodies are localized in the LPS of this gram-negative anaerobe.

The influence of third-generation cephalosporins on the aerobic intestinal flora.

The influence of three third-generation cephalosporins with varying degrees of biliary excretion on the aerobic flora was investigated. The faecal flora prior to therapy with one of these substances consisted mainly of anaerobic bacilli. Escherichia coli was present in concentrations of 10(9) organisms/g stool. Candida albicans and enterococci were observed in concentrations of 10(5) - 10(6) organisms/g stool. Within 24 hours after the administration of ceftriaxone and cefoperazone, the gram-negative aerobic flora was completely eradicated. C. albicans and enterococci increased to 10(9) organisms/g stool. Between the third and tenth days (mean 6.7 days) of therapy Pseudomonas aeruginosa, Enterobacter and Citrobacter in this order of frequency reappeared in the faecal flora with complete resistance to all betalactam antibiotics. C. albicans and enterococci decreased to 10(7) organisms/g stool. The anaerobic flora was largely unaltered. In contrast, cefotaxime had only a moderate influence on the aerobic faecal flora. Concentrations of gram-negative organisms decreased to 5 X 10(7) organisms/g stool during the first five days of therapy; the concomitant increase in C. albicans and enterococci was approximately 1 log 10. No alterations in the susceptibility pattern were observed. We would like to emphasize that substantial alterations of the faecal flora and the susceptibility pattern of antibiotics may accompany the use of antimicrobial agents, particularly those with a high degree of biliary elimination.

Influence of third-generation cephalosporins on aerobic intestinal flora.

Excretion of an antibiotic in bile may result in high intra-intestinal concentrations and thus alteration in the faecal flora. We investigated the effects of cefoperazone (75% biliary excretion), ceftriaxone (45%) and cefotaxime (5%) on the aerobic faecal flora. Cefoperazone reduced numbers of normal Gram-negative bacilli and selected resistant Pseudomonas, Serratia and Klebsiella-Enterobacter. Ceftriaxone was similar. However, cefotaxime had little effect on the normal Gram-negative flora, and did not promote the emergence of resistant organisms.

Familial occurrence of syngnathia congenita syndrome.

A case of familial occurrence of syngnathia congenita in mother and child is described; this syndrome has been seen only sporadically until now. Due to the distinct appearance of the intraoral chords--they were situated on both sides between the ridges of the jaw and also between the left half of the bifid uvula and the retrolingual region--a relationship to the autosomal-dominantly transmitted Cleft Palate Lateral Synechiae Syndrome (CPLS-Syndrome) is suspected. Complete penetrance with different expressivity may explain the different clinical manifestations of the cases seen up to now and the absence of bifid uvula in the mother of our patient. The probable pathogenesis during embryological development is discussed.

[Frequency of Kongenital Adrenal Hyperplasia (author's transl)].

The frequency of homozygous congenital adrenal hyperplasia in Tyrol is found to be 1 : 8991, the gene-frequency for congenital adrenal hyperplasia 1 : 95 and the frequency of heterozygous congenital adrenal hyperplasia 1 : 48. Our data is compared on a numerical and statistical base with that in Zürich and Munich with regard to the frequency of congenital adrenal hyperplasia, to its distribution with and without salt loss and to its sex-distribution. According to our study one may assume a frequency of homozygous congenital adrenal hyperplasia in Tyrol, Zürich and Munich of 1 : 7000--10,000.

[Complete parenteral nutrition in childhood].

Complete parenteral nutrition by means of continuous intravenous drip into large veins, over a long period, has already shown itself to be of therapeutic use in the field of pediatrics. While the nutritional-physiological aspect of this therapeutic method is clear -- it depends on an accurate and sufficient supply of water, salts, glucose, amino-acids, triglycerides and essential fatty acids, vitamins and trace elements -- in practice it presents difficulties which though often serious are not insurmountable. Especially are to cite the septic complications, which are nearly imperceptible during their development. They are only to accept in view of the often almost hopeless condition of the child, who would be lost without complete parenteral feeding. Similar problems arise through metabolic complications which are caused non rarely only by insufficient dosages and lack of careful supervision but it is generally possible to correct these at an early stage. Complete parenteral nutrition must be exactly indicated. It is indeed a great therapeutic help, particularly when over a longer period -- at least a week or longer -- oral nutrition is impossible or insufficient. Practicall experiences will be reported. A retrospective assessment of 50 cases has shown the tendency (through taking too much care?) to hold the quantity of liquids and supply of calories too short and to administer too much carbohydrates and too little fat.

Successful automatic external defibrillator operation by people trained only in basic life support in a simulated cardiac arrest situation.

OBJECTIVE: To show whether in an in-hospital cardiac arrest, early defibrillation can also be performed by hospital staff trained only in basic life support. BACKGROUND: The International Liaison Committee on Resuscitation (ILCOR) endorses the concept that in many settings non-medical individuals should be allowed and encouraged to use defibrillators. METHODS: Five different groups of hospital staff were evaluated whether they were able to correctly operate an automatic external defibrillator in a simulated sudden cardiac arrest situation without any prior instruction. The participants were assigned either to the 'basic life support-trained' group (BLS, n = 40, or to the 'advanced life support-trained' group (ALS, n = 40). RESULTS: All persons of the 'only BLS-trained' group delivered the three sequential ('stacked') shocks with the automatic external defibrillator when persistent ventricular fibrillation was simulated. The 'ALS-trained' persons successfully delivered the three shocks with the automatic external defibrillator in 98% of the cases. When this group used a conventional defibrillator, only 88% were able to deliver the three shocks, however they were able to do it significantly more quickly. CONCLUSION: Using an automatic defibrillator without any prior instruction, even persons trained only in BLS were able to deliver three sequential shocks in a simulated persistent ventricular fibrillation cardiac arrest.

[Ultrasonographic examination of the hip joint region and bony pelvis in cattle].

Transcutaneous and transrectal ultrasonographic examination of the hip joint region and the pelvis was carried out in 7 cadavers, transcutaneous ultrasonography in 17 healthy young and adult cattle, and transrectal sonography was performed in 12 healthy cows in order to study the normal ultrasonographic appearance of these regions. 7.5 MHz linear-, 5.0 MHz and 3.5 MHz convex transducers and a 7.5 MHz rectal probe were used. The bone surfaces of the greater trochanter, the femoral neck and head, the acetabulum and the other pelvic bones were visualised as hyperechoic contours. The coxofemoral joint space was identified in all cadavers and live cattle. The joint pouch could not be visualised, neither in cadavers nor in live cattle. After experimental filling of the coxofemoral joint pouch by injection of 35-45 ml eosin-solution it appeared as a large anechoic zone between the articular surface and the echogenic joint capsule. The inner contours of the pelvic girdle, both iliosacral joint spaces, the abdominal aorta and the external iliac arteries were depicted clearly by transrectal ultrasonography. The practical application of diagnostic ultrasound in these regions is demonstrated in clinical patients suffering from a septic coxarthritis and a sequestration of a part of the tuber coxae following an open fracture. These results serve as reference data for ultrasonographic investigation of disorders of the hip joint and the pelvic region in cattle.
