    Possible association between loudness dependence of auditory evoked potentials and tryptophan hydroxylase-alleles in alcoholics (2000)
    Oxford, UK : Blackwell Publishing Ltd
    Addiction biology 5 (2000), S. 0

    Notizen: The serotonergic neurotransmission was suggested to play an important role in the aetiology of alcoholism. This study explores the association between tryptophan hydroxylase (TPH)-alleles and Loudness Dependence of Auditory Evoked N1/P2 Potentials (LDAEP). The TPH is the rate-limiting biosynthetic enzyme in serotonergic pathway. The LDAEP is one of the best validated non-invasive indicators for serotonergic neurotransmission. A sample of 54 alcoholics was recruited. N1/P2 potentials were evoked by five different sound intensities. A dipole source analysis using BESA (brain electric signal topography) was performed and intensity dependence was computed. The TPH intron 7 polymorphism was determined by using PCR in DNA samples. There was a weak but significant association between low LDAEP and the L-TPH allele. No influence from an individual's history of alcohol dependence or a positive family history of alcohol dependence on LDAEP was found. The weak but significant relationship found between L-TPH-allele and high serotonergic neurotransmission may contribute to a more detailed neurobiological characterization of alcohol dependents using functional and genetic parameters.

    Melanocytes in nevi and melanomas synthesize basement membrane and basement membrane-like material. An immunohistochemical and electron microscopic study including immunoelectron microscopy (2000)

    Notizen: Light microscopic studies have shown that nevus cell nests and melanoma nests are surrounded by basement membrane (BM) material containing type IV collagen and laminin. This study confirms this by electron microscopy and relates it to proteins which interact with the basement membrane. Nevi except for dysplastic and Spitz nevi, malignant melanomas, and melanoma metastases were studied by immunohistopathology, routine electron microscopy (EM), and immunoelectron microscopy. The lesions were incubated with monoclonal antibody (moAb) against type IV collagen, laminin, and the integrin α6 and studied by light microscopy. In addition, melanomas were studied by immuno-EM after incubation with a moAb against matrix metalloproteinase-2 (MMP-2). Nevus cell nests and melanoma nests are surrounded by BM material containing type IV collagen and laminin by immuno-EM. The BM material various in thickness and is amorphous. Type IV collagen, laminin, and MMP-2 are synthesized by melanoma cells as well as adjacent fibroblasts. Destruction or loss of the BM is not mandatory for melanoma invasion or even metastasis. Possibly the BM material is a protective wall for melanoma cells. Interactions between melanocytes and the extracellular matrix of which the BM is a part, can be traced back to the migration of melanocytes from the neural crest.

    Notizen: Objective:  A possible contact allergy to herbal teas, in particular those derived from the Asteraceae plant family, was investigated in patients allergic to sesquiterpene lactones (SL).Method:  Twenty patients with a contact allergy to SL were recalled and patch-tested with aqueous, ethanol and acetone extracts of 8 different herbal teas based on Asteraceae plants as well as with parthenolide and other SL.Results:  In 18/20 patients with SL allergy there were positive test reactions to the Asteraceae teas, mainly to those based on German chamomile, dandelion and milfoil. Among the SL, parthenolide was the most frequent co-reactor.Conclusion:  Most patients with a contact allergy to SL are allergic to commercial teas derived from the Asteraceae plant family as well.

    Notizen: Background:  Hydrochloric acid is formed in water solutions of gold trichloride. Hydrochloric acid in contact with aluminium generates hydrogen gas which can reduce and transform trivalent gold to elemental gold.Objective:  To investigate whether patch testing with aqueous gold trichloride can cause false positive (irritant) reactions in patients without contact allergy to gold and false negative reactions in patients with gold allergy.Methods:  13 patients with and 13 patients without positive patch test reactions to gold sodium thiosulfate were tested with gold trichloride in 2 different vehicles, water and alkaline buffer, using 2 different test techniques, the Finn Chamber technique with aluminium chambers and van der Bend technique with polypropene chambers.Results:  Irritant patch test reactions were obtained with aqueous gold trichloride tested in van der Bend chambers in 10 patients without gold allergy. In gold-allergic patients no positive test reactions were obtained from aqueous gold trichloride in Finn chambers while 2 positive test reactions were obtained from gold trichloride in alkaline buffer tested in van der Bend chambers.Conclusion:  If gold trichloride is patch tested in wrong vehicle and with wrong test technique irritant test reactions may occur which can be misinterpreted as positive allergic reactions in patients without gold allergy as well as negative reactions in patients with gold allergy.

    Notizen: Abstract The H-basis concept allows, similarly to the Gröbner basis concept, a reformulation of nonlinear problems in terms of linear algebra. We exhibit parallels of the two concepts, show properties of H-bases, discuss their construction and uniqueness questions, and prove that n polynomials in n variables are, under mild conditions, already H-bases. We apply H-bases to the solution of polynomial systems by the eigenmethod and to multivariate interpolation.

    Have some guidelines for the treatment of acute bipolar depression gone too far in the restriction of antidepressants? (2000)
    Springer
    European archives of psychiatry and clinical neuroscience 250 (2000), S. 57-68 
    Details
    ISSN: 1433-8491
    Schlagwort(e): Key words Bipolar depression ; Tricyclic antidepressants ; Selective serotonin re-uptake inhibitors ; Drug treatment of acute bipolar depression

    Thema: Medizin
    Notizen: Abstract This paper gives a critical review of recommendations concerning the drug treatment of acute bipolar depression. The suggestions of different guidelines and consensus papers, especially in US-American and Canadian psychiatry, have a strong tendency against antidepressants in bipolar depression; they prefer mono-therapy with mood stabilizers and, in the case of co-medication with mood stabilizers and antidepressants in severe depression, to withdraw the antidepressant as early as possible. The intention of this restrictive use is to avoid the risk of mania and the risk of rapid cycling induced by antidepressants. However, apparently the risk of suicidal acts, which is as prominent in bipolar depression as in unipolar depression, has been totally neglected. Furthermore, the fact that none of the mood stabilizers have proven their antidepressive efficacy leads not only to the risk of depression-related suicidal behavior but also to the risk of chronicity of depressive symptoms due to undertreatment. Altogether the view expressed in some guidelines and consensus papers appears not well balanced. Furthermore, the fact that apparently the selective serotonin re-uptake inhibitors and possibly some other modern antidepressants have only a low risk of inducing a switch to mania should stimulate a rewriting of the guidelines on drug treatment in acute bipolar depression in a less restrictive way concerning the use of antidepressants.

    Suicidality in bipolar compared to unipolar depressed inpatients (2000)

    Notizen: Abstract The aim of the present analyses was to evaluate differences in suicidality (past suicide attempts, suicidal thoughts at time of admission and completed suicides during the hospital stay) between bipolar and unipolar depressed inpatients. Apart from a higher frequency of past suicide attempts in bipolar depressed patients (26.6% in bipolar vs. 17.8% in unipolar patients), findings do not indicate any further differences in suicidality (suicidal thoughts (about 40% in both groups) and completed suicides during the hospital stay (0.8% in both groups)) between bipolar and unipolar patients. Factors with a predictive value for suicidal thoughts at the time of admission were a positive family history for affective disorders, past suicide attempts, and the depressive and paranoid hallucinatory syndrome (all associated with an increased risk). Female gender, an older age at hospitalisation and a longer duration of the illness were found to be associated with a lower probability for having suicidal tendencies at the time of admission. The risk for committing suicide during the hospital stay was increased if the patients had a history of past suicide attempts and suicidal thoughts at the time of admission. A more pronounced depressive syndrome at time of admission was slightly associated with a lower risk of committing suicide.
