    Notes: Rationale Previous data have suggested that glutathione-S-transferase (GST) genotypes are important in determining the rate of lung function growth in childhood. This effect was most marked in Caucasian children with asthma.Objectives We investigated the association of lung function with GSTM1, GSTP1 and GSTT1 genotypes in Caucasian families with asthma.Methods Four hundred and eighteen children and 316 parents from 224 Caucasian families were recruited via a child with asthma, the proband. Associations between lung function and GST genotype were determined using multilevel models.Results There were no observed associations between lung function and GST genotype in parents. However, in the children, the GSTP1 val105/val105 and GSTM1 null genotypes were associated with significantly higher forced expiratory volume in 1 s (FEV1) and FVC values as percentage of predicted. This effect was not statistically significant in the probands but was marked in their siblings in whom GSTP1 val105/val105 was associated with 9.4% higher FEV1 and 10.7% higher FVC (P=0.005 and 0.001, respectively). The GSTM1 null genotype was associated with a 6.7% higher FEV1 and 4.1% higher FVC (P=0.003 and 0.063, respectively). These effects remained significant after correcting for the confounders of individual atopic status, tobacco smoke exposure and familial aggregation of lung function values.Conclusions GSTM1 and GSTP1 genotypes are important determinants of lung function in childhood. The smaller differences seen in probands are predicted by a simple model in which more rapid decline in lung function is seen in these individuals.

    Notes: Maternal factors are known to influence the heritability and expression of asthma and atopy. We report the association of maternal, paternal and proband GSTP1 genotype with lung function in 145 Caucasian children with asthma. GSTP1 Val105/Val105 and Ala114/Val114 genotypes in the child were associated with non-significant increases in lung function (forced expiratory volume in 1 second (FEV1), forced vital capacity (FVC) and the FEV1/FVC ratio). Paternal genotype had no influence on lung function in the child. In contrast, maternal GSTP1 Val105/Val105 genotype was significantly associated with offspring lung function and was strongly predictive of FEV1/FVC (Val105/Val105 105.2%, Ile105/Val105 and Ile105/Ile105 97.9% p = 0.006) and maternal GSTP1 Ala114/Val114 genotype was associated with significantly higher FEV1 (Ala114/Val114 109.0%, Ala114/Ala114 99.0% p = 0.008), and FEV1/FVC ratios (Ala114/Val114 104.1%, Ala114/Ala114 98.2% p = 0.04). The associations between maternal GSTP1 Val105/Val105 genotype and FEV1/FVC and maternal GSTP1 Ala114/Val114 genotype and FEV1 remained significant (p = 0.003 and p = 0.007) after correction for child and maternal atopic status, passive smoke exposure, smoking during pregnancy, individual and paternal GSTP1 genotype and was independent of transmission to the child. These data support the hypothesis that maternal GSTP1 genotype can act as a specific risk factor which has ex utero consequences for children with asthma. As a child's genotype is not independent of maternal genotype, effects seen in candidate gene studies may be due at least in part to this phenomenon.

    A randomized cross-over study to compare PUVA and extracorporeal photopheresis in the treatment of plaque stage (T2) mycosis fungoides (2004)

    Notes: PUVA is a well-established and effective treatment for plaque stage mycosis fungoides (MF) but its use is limited on a long-term basis because of the risk of cutaneous carcinogenesis. A further disadvantage is that nonexposed areas (sanctuary sites) often develop persistent disease. Therefore it is important to find alternative methods of treatment. Extracorporeal photopheresis (ECP) is a form of photochemotherapy that involves exposure of white blood cells to UVA with psoralens and can be effective in Sézary syndrome and erythrodermic cutaneous T-cell lymphoma. The aim of this study was to compare the efficacy of PUVA and ECP in the treatment of patients with T2 plaque stage (Stage 1B) MF who had a detectable peripheral blood T-cell clone. The study was of a cross-over design. Sixteen patients were randomized to receive either PUVA twice weekly for 3 months followed by ECP once monthly for 6 months at relapse, or vice-versa. Response was assessed by monthly skin scores and peripheral blood T-cell clonality. Ten patients received PUVA initially and six ECP initially. Eight patients completed the study. Skin scores taken at the completion of each treatment arm in patients who completed the study were 113 units better (confidence interval, 42–184 units) following 3 months PUVA than 6 months ECP (P = 0.002). Peripheral blood T-cell clones were detectable in all patients post-treatment. This study indicates that ECP is not effective in the treatment of plaque stage (1B/T2) MF even in patients with molecular evidence of a peripheral blood T-cell clone. Although PUVA was more effective than ECP, neither treatment modality cleared malignant T-cells from the peripheral blood.

    Progressive osseous heteroplasia resulting from a new mutation in the GNAS1 gene (2004)

    Notes: Progressive osseous heteroplasia (OMIM 166350) is a rare autosomal dominant condition that presents in childhood as dermal ossification and may progress deeper to involve subcutaneous fat and connective tissue. Recently, paternally inherited inactivating mutations in the GNAS1 gene on chromosome 20q13 have been implicated in the pathogenesis, although sporadic cases have also been reported. We report a 9-year-old British Chinese girl with progressive osseous heteroplasia resulting from a de novo missense mutation (W281R) in the GNAS1 gene. She is of small stature (0.4th centile) and started to develop skin lesions at the age of 9 months. These have been confirmed histologically as osteoma cutis. She is of normal intelligence and development and has no dysmorphic features. The GNAS1 gene exhibits imprinting and maternally inherited mutations have previously been shown to result in Albright's hereditary osteodystrophy (OMIM 103580) with pseudohypothyroidism type 1a, whereas paternally inherited mutations result in progressive osseous heteroplasia or the Albright's hereditary osteodystrophy phenotype with pseudopseudohypothyroidism (OMIM 300800). With only nine mutations of the GNAS1 gene reported so far in progressive osseous heteroplasia, this new mutation helps to extend further the genotype–phenotype correlation.

    Notes: We present a patient with a desquamating predominantly flexural erythema and glossitis due to a combination of alcoholism, zinc deficiency and amino acid deficiency. A similar clinical picture to necrolytic migratory erythema can be seen with zinc deficiency or protein malnutrition, often in patients with alcoholic liver disease, in the absence of glucagonoma. The speed of clinical improvement following zinc replacement therapy, usually within days to weeks, is striking, confirming the clinical diagnosis.

    Systemic Hodgkin’s lymphoma in a patient with Sézary syndrome (2000)

    Notes: We report a case of a 71-year-old male with Sézary syndrome diagnosed in 1996 who subsequently developed systemic Hodgkin’s lymphoma. His only past treatment was bath psoralen plus ultraviolet A. He has since been treated with multiagent chemotherapy (ChlVPP/PABLOE) which induced a remission in his Hodgkin’s disease. Eighteen months later he remains in remission from Hodgkin’s disease but the Sézary syndrome remains active. He has also developed a squamous cell carcinoma on the upper lip. Sézary syndrome is a primary cutaneous T-cell lymphoma characterized by a malignant proliferation of CD4-positive cells in the skin and peripheral circulation. The CD4 count may be markedly elevated but this results from expansion of a neoplastic T-cell clone and there is a relative lymphopenia of normal T cells leading to a degree of immunoparesis. Immunosuppression is known to be associated with an increased rate of malignancies and this may account for the occurrence of Hodgkin’s disease and squamous cell carcinoma in this patient with Sézary syndrome.

    Notes: Zusammenfassung Eine Methode für selektive Solubilisierung der Zellen und verschiedener Organellen von Ciliaten, welche auf einer speziellen Anwendung der MethodeMazia undDan zur Gewinnung isolierter Mitoseapparate von Seeigeleiern beruht, wird beschrieben. Die Ciliaten werden bei niedriger Temperatur in 40% Ethanol extrahiert und mit Digitonin behandelt. In salzfreier Digitoninlösung (1% aq) bleiben nur das Wimpernsystem und damit verbundene Strukturen erhalten und können in genügender Menge für chemische Analysen gewonnen werden. Durch Zugabe verschiedener Mengen von KCl ist es möglich, auch Zellkerne, Pellicula, usw. vor der Auflösung zu schützen und durch differentielle Zentrifugierung zu isolieren.
