    Description / Table of Contents: Zusammenfassung Es wird über einen Fall von testiculärer Feminisierung berichtet. Patient erstrebt Geschlechtsumwandlung, nachdem er bis zum 3. Jahr als Mädchen, dann als Junge aufgezogen wurde und unter seinen überwiegend weiblichen sekundären Geschlechtsmerkmalen leidet. Körperlich sind hervorzuheben: Männliches Kerngeschlecht, Leistenhoden mit normal entwickelten Leydig-Zellen, überwiegend weibliches äußeres Genitale mit fehlenden inneren Genitalorganen, Klitorishypertrophie, Mammae-Entwicklung zur Zeit der Pubertät, fehlende Bart- und Axillarbehaarung, Genitalbehaarung vom weiblichen Typ. Die endokrinologische Untersuchung ergab: Hoch normale Gonadotropinwerte, für Männer hoch normale Plasmatestosteronwerte, leichter Anstieg des Testosteron auf HCG, kein Anstieg auf ACTH, niedrig normale Östrogenwerte. Wenn testiculäre Feminisierung mit Klitorishyperplasie und anderen maskulinen Zeichen verbunden ist, können psychosexuelle Probleme auftreten. Ein deutlich transsexuelles Begehren ist aber auch bei diesen „unvollständigen“ Fällen testiculärer Feminisierung bisher nicht berichtet worden. Unsere Beobachtung verweist auf die Bedeutung der genital sichtbaren Intersexualität für die Bestimmung des Geschlechts nach der Geburt und für die Übernahme der Geschlechtsrolle durch den Heranwachsenden.
    Notes: Summary A case of testicular feminization is described. The patient, brought up as a girl up to the age of three years, then as a boy, suffers from his predominantly female sex characteristics and requests sex reversal. Physical examination: male nuclear sex, inguinal testes with normally developed Leydig cells, predominantly female external genitalia without internal genitalia, hypertrophy of the clitoris, development of mammae at time of puberty, pubic hair of the female type, no facial or axillary hair. Endocrinologic findings: high normal gnoadotrophins, plasma testosterone in the upper normal range for males, slight increase of testosterone after injection of HCG, no increase after ACTH, low normal oestrogene. In cases of testicular feminization with hypertrophy of the clitoris and other signs of masculinization, psycho-sexual problems often arise. Transsexualism has not yet been described even in the incomplete syndrome. Our observation points to the importance of visible signs of intersexuality for the determination of the sex after birth and for the acceptance of the gender role in childhood and adolescence.

    Notes: The consequences of a diagnosis of occupational contact dermatitis (OCD) were investigated using cases available from the voluntary surveillance scheme, EPIDERM. Cases of OCD reported from November 1994 to September 1995 were identified and sampled to give at least 100 cases of allergic, irritant and mixed OCD reported by consultant dermatologists (344 cases) and occupational physicians (377 cases). A questionnaire was sent to the reporting physician to elicit further information. 512 completed questionnaires were returned, of which 510 were eligible for analysis. Among cases reported by dermatologists (n = 286) and occupational physicians (n = 224), 7% (6.3%) had been unemployed and 16.8% (20.1%) had taken sick leave. 3 factors independently predicted time off work in a logistic regression analysis: age OR = 1.25 (95% CI, 1.05–1.49), allergic dermatitis OR = 1.77 (95% CI, 1.13–2.79) and medicolegal assessment OR = 4.42 (95% CI, 2.20–8.89). Overall, 15.7% did not improve clinically between the first and last visit. Those who did not improve had been exposed to the agent for longer (mean 7.6 years) than those who did (5.3 years) (p = 0.09). In patients ≤ 45 years, those reported to be atopic failed to improve (25.4%) more often than those not atopic (13.4%) (p = 0.04). The substantial numbers (21%) with time off work and with persistent dermatitis suggest that OCD continues to have a significant impact on workers and their employers.

    Notes: Abstract— We describe a method for the fluorometric determination of 5-hydroxyindoles in the physiological range of 0.010–1.30 μg/ml of whole blood by means of an autoanalytical procedure. Serotonin is dialysed free from haemolysed blood constituents and a complex between 5-HT and o-phthaldialdehyde is formed in the dialysand to provide a considerable increase over the native fluorescence of 5-HT in strong acid. The method has been evaluated and considered to be accurate for the continuous monitoring of levels of 5-HT in whole blood and for the determination of cerebral arteriovenous differences. The range of values for human patients with cerebrovascular disease was 0.09–0.34 μg/ml of whole blood. In experimental studies on the baboon the range was 0.538–1.28 μg/ml. A mean positive cerebral arteriovenous difference for 5-HT (and possibly other 5-hydroxyindoles) of 0.037 μg/ml was measured in 10 baboons. This finding suggests the possibility of physiological movement of 5-HT and 5-hydroxyindoles into brain across the blood-brain barrier.

    Notes: Background Human rhinoviruses (RVs) are the most common precipitants of asthma exacerbations. RV infection of bronchial epithelium results in local airway inflammation inducing eosinophil recruitment and activation. Induction of eosinophil chemoattractants could represent a central mechanism, as well as a prime target for intervention.Objective To assess the effect of RV infection on mRNA expression and production of eosinophil chemoattractants by bronchial epithelial cells in-vitro.Methods BEAS-2B cells were infected with major and minor RVs and the mRNA expression of IL-8, RANTES, MIP-1α, eotaxin, eotaxin-2, MCP-2, MCP-3 and MCP-4 was assessed by reverse transcription PCR. In cases where mRNA induction was observed, a fluoroimmunoassay was used to confirm protein production. To assess the virus-specificity of the observed reactions, cells were also exposed to inactivated RVs.Results RV infection was able to up-regulate mRNA expression of IL-8, RANTES, MIP-1α, eotaxin and eotaxin-2, did not affect MCP-4, while MCP-2 and MCP-3 were not expressed either at baseline or after virus infection. Protein production was confirmed for IL-8, RANTES and eotaxin, but not for MIP-1α. When RVs were inactivated cytokine up-regulation was almost completely lost.Conclusion Infection of bronchial epithelial cells with RVs results in the production of a wide array of mediators that are able to chemoattract eosinophils. These include the eosinophil-specific molecules eotaxin and eotaxin-2, in addition to IL-8 and RANTES, which are the most abundant. Eosinophil recruitment after RV infection of bronchial epithelium could represent a central event in the pathogenesis of virus-induced asthma exacerbations.

    Notes: Throughout the world there is a trend towards retaining crop residues rather than burning them. For this reason, changes in soil chemistry and aggregation in a Vertisol induced by 59 years of burning or green cane harvesting with or without annual fertilizer applications were investigated. Crop residues were either burnt prior to harvest with the harvest residues raked off (R1), burnt prior to harvest with the harvest residues left on the soil surface (R2), or left unburnt with all the trash left on the soil surface (R3). Concentrations of organic C in the surface 10 cm of soil increased with fertilizer applications and with increasing amounts of crop residue returned in the order R1 〈 R2 〈 R3. Fertilizer applications caused an accumulation of residual P in both inorganic (Pi) and organic (Po) forms. A sequential P fractionation showed that fertilizer P accumulated in both labile and recalcitrant Pi and Po forms, and trash retention caused an accumulation of recalcitrant Po. Concentrations of K decreased in the unfertilized R1 and R2 treatments because K reserves were depleted. By contrast, there was an increase in the concentrations of K in the fertilized R3 treatment. The soil became more acid on the fertilized and, to a lesser extent, trash retention plots. We attribute this to nitrification and subsequent nitrate leaching. Acidification resulted in a loss of exchangeable Ca and Mg, a decrease in ECEC, and an increase in the concentrations of total and monomeric Al in soil solution, in exchangeable Al3+ and in the buffering reserve of non-exchangeable Al associated with organic matter. Aggregate stability was increased by increasing crop residues but decreased by fertilizer applications. The decrease was attributed to an increase in the proportion of exchangeable cations present in monovalent form due to applications of fertilizer K and leaching of Ca and Mg. We conclude that trash retention and annual fertilizer applications have substantial long-term effects on both organic matter status and soil pH and therefore on other soil chemical and physical properties.
