[Lay version of the 2018 EULAR recommendations for physical activity in people with inflammatory arthritis and osteoarthritis : Translation into German and linguistic validation in German-speaking countries with people affected]. / Die laienverständliche Version der 2018 EULAR Empfehlungen zu körperlicher Aktivität von Menschen mit entzündlich-rheumatischen und degenerativen Erkrankungen : Übersetzung ins Deutsche und sprachliche Validierung im deutschsprachigen Raum mit Betroffenen.

BACKGROUND: Physical activity and exercise are beneficial for people with rheumatic diseases; however, recommendations for the management of rheumatoid arthritis (RA), spondyloarthritis (SpA) and hip- and knee osteoarthritis (HOA/KOA) are usually unspecific with respect to mode and dose of exercise. This is why the 2018 EULAR recommendations for physical activity in people with inflammatory arthritis and osteoarthritis were formulated. The recommendations consist of 4 overarching principles and 10 recommendations. These were also published as a lay version in the English language. AIM: Translation of the lay version into German and its linguistic validation in Austria, Germany and Switzerland. METHODS: A professional translation was reviewed by the authors, including people with, RA, SpA, HOA/KOA from the three German-speaking countries, which provided a prefinal lay version. Subsequently, eight interviews with people with RA, SpA, HOA/KOA were conducted in each country to evaluate understandability, wording, completeness and feasibility of the prefinal lay version. Finally, the authors, i.e. those with RA, SpA, and osteoarthritis, anonymously rated their agreement to the final lay version on a 0-10 scale. RESULTS: The professional translation was substantially revised by the authors and based on the interviews. Formulations were adapted to increase readability and understandability and specify statements. Comments that would have changed content or structure were not considered. Average agreement with the particular recommendations was between 10 (SD 0) and 7.6 (SD 1.67). DISCUSSION: For people with RA/SpA/HOA/KOA the EULAR physical activity recommendations should be available in their mother language. The final German lay version is valid and accepted across all three German-speaking countries. Thus, the physical activity recommendations can be provided to people with rheumatic diseases in an understandable and feasible way.

Comparison of environmental risk factors for esophageal atresia, anorectal malformations, and the combined phenotype in 263 German families.

Esophageal atresia with or without tracheoesophageal fistula (EA/TEF) and anorectal malformations (ARM) represent the severe ends of the fore- and hindgut malformation spectra. Previous research suggests that environmental factors are implicated in their etiology. These risk factors might indicate the influence of specific etiological mechanisms on distinct developmental processes (e.g. fore- vs. hindgut malformation). The present study compared environmental factors in patients with isolated EA/TEF, isolated ARM, and the combined phenotype during the periconceptional period and the first trimester of pregnancy in order to investigate the hypothesis that fore- and hindgut malformations involve differing environmental factors. Patients with isolated EA/TEF (n = 98), isolated ARM (n = 123), and the combined phenotype (n = 42) were included. Families were recruited within the context of two German multicenter studies of the genetic and environmental causes of EA/TEF (great consortium) and ARM (CURE-Net). Exposures of interest were ascertained using an epidemiological questionnaire. Chi-square, Fisher's exact, and Mann-Whitney U-tests were used to assess differences between the three phenotypes. Newborns with isolated EA/TEF and the combined phenotype had significantly lower birth weights than newborns with isolated ARM (P = 0.001 and P < 0.0001, respectively). Mothers of isolated EA/TEF consumed more alcohol periconceptional (80%) than mothers of isolated ARM or the combined phenotype (each 67%). Parental smoking (P = 0.003) and artificial reproductive techniques (P = 0.03) were associated with isolated ARM. Unexpectedly, maternal periconceptional multivitamin supplementation was most frequent among patients with the most severe form of disorder, i.e. the combined phenotype (19%). Significant differences in birth weight were apparent between the three phenotype groups. This might be attributable to the limited ability of EA/TEF fetuses to swallow amniotic fluid, thus depriving them of its nutritive properties. Furthermore, the present data suggest that fore- and hindgut malformations involve differing environmental factors. Maternal periconceptional multivitamin supplementation was highest among patients with the combined phenotype. This latter finding is contrary to expectation, and warrants further analysis in large prospective epidemiological studies.

Confirmation of putative stormwater impact on water quality at a Florida beach by microbial source tracking methods and structure of indicator organism populations.

The effect of a stormwater conveyance system on indicator bacteria levels at a Florida beach was assessed using microbial source tracking methods, and by investigating indicator bacteria population structure in water and sediments. During a rain event, regulatory standards for both fecal coliforms and Enterococcus spp. were exceeded, contrasting with significantly lower levels under dry conditions. Indicator bacteria levels were high in sediments under all conditions. The involvement of human sewage in the contamination was investigated using polymerase chain reaction (PCR) assays for the esp gene of Enterococcus faecium and for the conserved T antigen of human polyomaviruses, all of which were negative. BOX-PCR subtyping of Escherichia coli and Enterococcus showed higher population diversity during the rain event; and higher population similarity during dry conditions, suggesting that without fresh inputs, only a subset of the population survives the selective pressure of the secondary habitat. These data indicate that high indicator bacteria levels were attributable to a stormwater system that acted as a reservoir and conduit, flushing high levels of indicator bacteria to the beach during a rain event. Such environmental reservoirs of indicator bacteria further complicate the already questionable relationship between indicator organisms and human pathogens, and call for a better understanding of the ecology, fate and persistence of indicator bacteria.

Carbamazepine maintenance treatment in outpatient schizophrenics.

A double-blind crossover trial was used to evaluate carbamazepine as the sole maintenance treatment of chronic, nonmanic schizophrenic outpatients whose conditions had been stabilized with the use of neuroleptics prior to study. Criteria of treatment effectiveness included the number of patients relapsing and time to relapse over a 95-day neuroleptic-free period during which either carbamazepine or placebo was administered. Relapse was determined by the concordance of psychiatric ratings and independent clinical judgements indicating significant worsening. Results for 27 patients (13 receiving carbamazepine and 14 receiving placebo) involved in the first phase of this treatment comparison were nondifferentiating. Corroborating descriptive findings in the second phase were available for 14 of these patients. There was no evidence supporting the existence of a treatment-relevant subgroup defined by episodic dyscontrol phenomena.

Effects of sex and age on growth hormone response to growth hormone-releasing hormone in healthy individuals.

The influence of age and sex on human GH secretion is controversial. In previous studies, serum GH responses to arginine and insulin-induced hypoglycemia were significantly higher in pre- and postovulatory women than in men. In contrast, recent studies suggest that GH responsiveness to GHRH is higher in normal young men than in age-matched women. To clarify the question of sex and age influence on GHRH-(1-44)-stimulated GH secretion, we studied 116 normal women and men (with body mass indexes of 18-25 and 19-26, respectively) between the ages of 18 and 95 yr. The peak serum GH increments after GHRH administration were significantly higher in premenopausal women than in age-matched men (P less than 0.003 for the age group 18-30 yr and P less than 0.03 for the age group 30-50 yr, as assessed by analysis of variance). The responses were not different in postmenopausal women and age-matched men. Multiple regression analysis revealed a significant negative correlation between GHRH-induced GH responses (integrated area under the curve) and age in both women (P less than 0.002) and men (P less than 0.001). In addition, we determined basal serum testosterone, estradiol, cortisol, and PRL levels in all subjects. Multivariate regression analysis of the GH responses to GHRH administration revealed a significant positive correlation (P less than 0.01) between serum estradiol and both GH increase and the area under the GH response curve. No correlation was found between GHRH-stimulated GH secretion and basal serum cortisol, testosterone, or PRL concentrations. Our data clearly demonstrate a marked influence of both sex and age on GHRH-stimulated GH secretion. We found a higher GH increase in premenopausal women compared with age matched-men and an age-dependent decrease in GHRH-stimulated GH secretion in both sexes. Furthermore, in women a significant influence of estradiol on GH secretion after GHRH administration could be demonstrated.

Tolerability of a new vitamin K1 preparation for parenteral administration to adults: one case of anaphylactoid reaction.

The efficacy and tolerability of a conventional vitamin K1 preparation containing polyoxyethylated castor oil as solubilizer were compared with those of a new compound containing mixed micelles as solubilizer in 30 patients. A statistically significant increase in the thrombotest was detected after treatment in both groups. No hematological or chemical toxicity was observed during the observation period. One patient had an anaphylactoid reaction after intravenous injection of the mixed micelles preparation. Intradermal testing yielded positive results. The authors conclude that intravenous administration of vitamin K preparations should be reserved for acute emergencies.

Prophylactic use of hyperimmunoglobulin for cytomegalovirus infection in heart transplantation.

Cytomegalovirus (CMV) infection in solid organ recipients can endanger the immunosuppressed patient and increase vulnerability to secondary infections and the high risk of rejection triggered by the viral disease. The effect of passive immunization against CMV was examined in 69 heart transplant patients. The patients received weekly administrations of 1 ml/kg of CMV hyperimmunoglobulin from the day of transplantation until the 30th postoperative day. Forty-four of the patients were monitored clinically and serologically up to the 120th postoperative day. Nine patients showed clinical and serologic signs of CMV infection; in 15 the only evidence of CMV infection was a rise in antibody titers. The remaining 20 patients showed no clinical or serologic signs of CMV infection. Three patients who were seronegative preoperatively remained seronegative until the end of the observation period. The results indicate a potential therapeutic benefit of hyperimmunoglobulin prophylaxis to prevent infectious complications due to CMV in heart transplant patients.

Removal of purgeable organic chlorine compounds by activated carbon adsorption.

The increasing demand for drinking water in the city of Cologne could no longer be met solely by ground water resources. A group of wells was placed in a meander of the Rhine River south of Cologne in order to draw bank-infiltrated ground water from the river. Geohydrological conditions at that location assure that the pumped raw water is mainly bank-infiltrated water from the Rhine River. The relatively long underground passage, of about 600 m, provides significant pretreatment of the river water.

Neurological status, sleep apnea frequency and blood oxygenation in six weeks old infants.

A study was carried out to investigate the correlation between sleep apnea frequency, blood oxygenation and neurological condition in 21 infants at six weeks of age with inconspicuous medical history. Polygraphic recordings of respiratory behaviour and transcutaneous blood gas monitoring lasted for at least five hours. To quantify the results of the neurological examination we established a neurological optimality score (NOS). We found statistically significant correlations between several indexes of apneas and indexes of blood oxygenation and NOS. Thus, a reduced NOS was strongly correlated with higher apnea frequencies and with pronounced drops of transcutaneous PO2-values. In addition all but one infant who were diagnosed as having a sleep apnea syndrome showed a greater than ten percent reduction of NOS. Some pathophysiological considerations to explain our findings are put forward and the possible role of the neuromodulator adenosine is emphasized.

Treatment and metabolic findings in extreme short-bowel syndrome with 11 cm jejunal remnant.

A full term girl survived nonresected, subtotal small-bowel gangrene. The length of the small-bowel remnant (only jejunum) measured 11 cm. Anastomosis was performed with insertion of a 3-cm-long antiperistaltic segment. The ileocecal valve remained intact. The jejunal remnant showed an increase in length of at least 1 m. The resorptive functions of the bowel residue recovered incompletely, particularly the ileal functions. Disturbances of calcium and phosphorus metabolism are now in the foreground; nevertheless, the child now manages to live without parenteral feeding.

Serum-erythropoietin concentration during acute cardiogenic pulmonary edema.

Reduced oxygen tension is regarded as the primary physiologic signal for the production of erythropoietin (EPO). There is little information available about early changes of EPO production in man due to severe hypoxia. The purpose of the present study was to examine the time course of EPO in serum of patients with acute cardiogenic pulmonary edema (ACPE). In 29 patients (seventy-five +/- six years, mean age +/- SEM) who were hospitalized within two hours after onset of symptoms of ACPE, serum EPO concentrations were monitored for up to seventy-two hours. At the moment of admission all patients showed significantly increased EPO concentrations of 121 +/- 64 mU/mL (mean +/- SEM) compared with a healthy population (15-35 mU/mL). Twenty-three patients who recovered within thirty minutes (group A) exhibited a quick return of their EPO serum levels to normal. The remaining 6 patients (group B) had a protracted clinical course and their EPO concentration showed a further increase up to the end of the observation period. The comparative monitoring of concentrations of alpha-1-proteinase inhibitor, antithrombin III, C-reactive protein, fibronectin, hapotoglobin, and transerrin in serum and plasma revealed no significant changes. Thus a major contribution of fluid shifts into or from the intravascular compartment to the observed changes in EPO concentration seems to be unlikely. The data suggest that the production and release of EPO in the kidneys due to altered oxygen delivery is a fast-responding mechanism.

Effect of manual lymphdrainage massage on blood components and urinary neurohormones in chronic lymphedema.

In an earlier paper we have shown that manual lymph drainage massage of edematous limbs can result in the excretion of up to 1 liter urine derived from reabsorption and transport from the interstitial fluid, simultaneously with significant changes in the excretion of urinary neurohormones. These findings indicated that histamine and serotonin were released from the edematous tissue and that circulation improved through increased output of adrenaline and noradrenaline. The results achieved led us to assume that similar changes may have occurred in the blood during treatment, and induced us to study the effect of manual lymphdrainage on various blood constituents and urinary neurohormones.

[Activity studies of an iron-vitamin B6 preparation for euteral treatment of iron deficiency anemia]. / Untersuchunger uber die Wirksamkeit eines Eisen-Vitamin B6-Präparates für die enterale Behandlung der Eisenmangelanämie

In 17 respectively 15 children with iron deficiency anemia the effect of a combined orally applicated iron-vitamin B6 therapy and iron therapy only was studied. Pyridoxal phosphate, activities of pyridoxal kinase and red cell GOT, and excretion of 4-pyridoxic acid in urine were measured as indices of vitamin B6 nutriture before therapy was started, on the 3rd and 6th day with therapy and on the 1st and 4th day after therapy was stopped. Red cells, concentration of hemoglobin, reticulocytes and hematokrit were simultaneously counted, whereas serum iron had been measured once only before therapy. A group of 22 hematologically healthy children was studied as controls. After iron therapy a decrease of vitamin B6 nutriture occured as a consequence of an increased requirement for pyridoxal phosphate for heme synthesis. Additional vitamin B6 was followed by a normal vitamin B6 nutriture and a significantly accelerating effect on heme synthesis.

[Our responsibility to children]. / Unsere Verantwortung für die Kinder.

The significant advances in medicine during this century have led to a shift in emphasis in paediatrics: whilst two thirds of all infant deaths still result from complications during the neonatal period, the sudden infant death syndrome has come to the fore, and in older children accidents and malignant disease account for most deaths. Chronic illness, physical disabilities and psychological disturbance are constantly gaining increased importance. I suggest four principal answers to the problems concerning children today: Scientific research taking into account the child's personality as a basis of real progress: Accentuation of health education in paediatrics; Training of cybernetic thinking--with respect to the child as a psychosomatic unity, the multifactorial pathogenesis of several diseases, and interdisciplinary teamwork between doctors and scientists. Empathetic attitude to the child as a special entity and wholly valid human being, with specific needs at each stage of development.

[4th Austrian SIDS Consensus-Consultation and the Viennese SIDS prevention campaign "Secure Sleep"]. / Osterreichisches SIDS-Konsensus-Gespräch anlässlich der Wiener SIDS-Präventionskampagne "Sicheres Schlafen".

Despite numerous investigations the pathophysiologic mechanisms of SIDS have not been fully elucidated. In large epidemiologic studies highly variable SIDS mortality rates were noted between different countries and cultures. This presumably is due not only to differences in diagnostics and classification of SIDS but also in lifestyle and newborn care. The common denominator is the identification and prevention of the main risk factors: smoking, sleeping in the prone position, over-heating, wrong "bedding". SIDS prevention campaigns that have focussed upon these risk factors have led to a dramatic reduction in the incidence of SIDS. In preparation for the SIDS prevention campaign of Vienna ("Safe Sleep") the content, strategy and procedure of the Austrian prevention campaigns were analysed. The current focus is to convey a clear and uniform message in personal conversations before and after birth of the child. These conversations with parents are the most important tool to detect SIDS related anxiety and a possibly increased risk of SIDS. In the last 30 years various polysomnographic parameters were published that were associated with an increased risk of SIDS. Today there is international consent that polysomnography is not an efficient screening method to demonstrate increased risk of SIDS. Therefore the use of polysomnography, besides research purposes, has been limited to investigating clinical symptoms of infants and children. Concerning monitoring it is important to note that--in contrast to the undisputed importance of monitoring breathing disorders--the effectiveness in SIDS prevention is unproven. State of the art are instruments that monitor heart and breathing rate and have adequate storage functions. The duration of monitoring should encompass the symptomatic period as well as a safety period of three months. The monitor should not be routinely prescribed for a year. The guiding principle is "As short as possible with stringent indication". Prerequisite for the monitoring is good instruction of the parents and a continuous consultation by competent outpatient clinics.

[Sudden infant death (SIDS) in Austria. How reliable is the diagnosis?]. / Der plötzliche Säuglingstod (SIDS) in Osterreich. Wie verlässlich ist die Diagnose?

The sudden infant death syndrome (SIDS) is the most frequent cause of death during the postneonatal period (2-12 months) in Austria. A retrospective analysis of the SIDS cases registered between 1988 und 1992, however, shows marked differences between the provinces with regard to the relative proportion of SIDS against total infant mortality figures. The use of different definitions for SIDS seems to be responsible for local differences. Thus, a standardized investigation for all sudden unexpected deaths is required (autopsy, histological investigations, death scene investigation). Furthermore, a uniform classification for sudden unexpected infant death should be applied.

Persistent hypercapnia in children after treatment of obstructive sleep apnea syndrome by adenotonsillectomy.

Obstructive sleep apnea syndrome (OSAS) in childhood is frequently in part a consequence of enlarged adenoids and/or tonsils and may lead to hypoxemia and hypercapnia during sleep. Whereas long-term blood gas alterations are well documented in adults, only few polygraphic data are available for children. It was the aim of this study to document blood gas alterations before and after treatment in this population. 9 children with OSAS (6 male, 3 female, median age 5.9 years, range 1.1-13.5 years) were investigated by polysomnography before and after adenotonsillectomy. Prior to intervention most children presented with moderate hypercapnia (ETCO2 mean 44.3 +/- 3.8 mm Hg, ETCO2 maximum 53.2 +/- 5.2) and hypoxemic episodes (oxygen saturation mean 93.2 +/- 3.2%, minimum 74.4 +/- 16.5%). Following adenotonsillectomy subsequent polygraphic investigations displayed normalisation of oxygen saturation (saturation mean 96.1 +/- 0.8%, minimum 90.1 +/- 3.1%). In contrast, moderate hypercapnia in several patients persisted up to five months after treatment (ETCO2 mean 44.9 +/- 2.8 mm Hg, ETCO2 maximum 51.2 +/- 3.6). Persistent hypercapnia most likely reflects an adaptation process of chemosensitivity and respiratory control due to preceding long-term hypercapnia.

[T-cell lymphoma (author's transl)]. / T-Zell-Lymphome

The percentage of T- and B-lymphocytes was determined by means of surface markers in 190 patients suffering from various lymphoproliferative disease. Characteristic T-cell lymphomas were diagnosed in 8 patients: 2 of these patients suffered from acute leukaemia, 2 from lymphoblastic lymphoma, 3 from mycosis fungoides and one from the Sézary syndrome. The clinical course of the disease in these patients, the clinical picture and the results obtained with various surface markers and with unspecific mitogens are described and discussed.

[Air pollution and sudden infant death in Graz 1982 to 1987]. / Luftverschmutzung und plötzlicher Säuglingstod in Graz im Zeitraum von 1982 bis 1987.

We correlated the incidence of the sudden infant death syndrome (SIDS) and the degree of air pollution in each district of Graz over a time period of five years. The degree of air pollution was derived from a mapping of epiphytical lichen vegetation by Grill et al. (1988). We found an increased incidence of SIDS in districts with poor air quality. Although this result is not statistically significant a possible increase in SIDS risk because of air pollution cannot be excluded. Some pathophysiological explanations are discussed.

[The chronically altered appendix in children. Cooperative work of the Austrian Society for Pediatric Surgery]. / Die "chronisch veränderte" appendix beim kind. Gemeinschaftsarbeit der Osterreichischen Gesellschaft für Kinderchirurgie.

In this multicentric study the anamnestic data and parents questionaires of 2-29 children were evaluated, whose appendix vermiformis at the time of operation showed no signs of inflammation. 31,1% macroscopically showed cicatrisation or fasciation, in 13,7% other enteral or gynaecological (1%) findings were present. In 1194 of the cases of patho-histological examination of the appendix had been made of which 36.4% were negative, 37.7% showed cicatrisation, 15,0% oxyuriasis and 10,4% coproliths. In the discussion of the significance of the chronically altered non-inflamed appendix we compared patients with and without macroscopical or microscopical alterations. We came to the conclusion that the probability-index as to sex, duration of symptoms, complexity of symptoms, incidence of postoperative well-being, proved the chronically altered appendix not to be an illness per se, but the result of spontaneously arrested inflammation. Since the rate of children admitted with a perforated appendix is high (15-20%) in comparison with the rate of complications after removal of non-inflamed appendices (2,9%), we believe that according to the diagnostical problems the principle can be maintained: in dubio pro operatione.
