Human serum elements' levels and leukemia: A first pilot study from an adult Greek cohort.

Background: The present study focuses on the evaluation of potential relationships between trace elements and acute and chronic types of leukemia, via the determination of their levels in human blood serum.

Methods: A total of 199 serum samples from a Greek cohort were examined, including both leukemia cases and controls. Elements' analysis was carried out using inductively coupled plasma mass spectrometry (ICP-MS) and demographic features such as age, gender, smoking habits and area of residence were recorded and statistically treated applying Shapiro-Wilk, Kolmogorov-Smirnov, Mann Whitney and Kruskal Wallis tests (p < 0.

25-hydroxyvitamin D in malignant pleural disease: a prospective cohort study.

Introduction: Growing evidence suggests a role of vitamin D in various cancers but the significance of vitamin D in malignant pleural disease remains unexplored. We sought to investigate the concentration and diagnostic role of 25-hydroxyvitamin D (25(OH)D) in malignant pleural effusions.

Materials And Methods: Prospective study of consecutive treatment-naïve patients with a new diagnosis of pleural effusion.

Gestational diabetes exhibits lack of carnitine deficiency despite relatively low carnitine levels and alterations in ketogenesis.

Objective: Previous studies have underlined the importance of the carnitine shuttle system and its dysfunction both in normal pregnancy and in type 1 and 2 diabetes. The objective of this paper was to delineate more systematically the role of the carnitine shuttle system in normal pregnancy and in gestational diabetes.

Methods: A total of 119 women matched for age comprised three groups: 40 normal adult non-pregnant women (NNP), 46 normal pregnant women with uncomplicated pregnancy (NP) and 33 women with gestational diabetes (GDM).

Mutational spectrum of the succinate semialdehyde dehydrogenase (ALDH5A1) gene and functional analysis of 27 novel disease-causing mutations in patients with SSADH deficiency.

Succinate semialdehyde dehydrogenase (SSADH; ALDH5A1) deficiency, a rare metabolic disorder that disrupts the normal degradation of GABA, gives rise to a highly heterogeneous neurological phenotype ranging from mild to very severe. The nature of the mutation has so far been reported in patients from six families world wide and eight different mutations were described. Here we report the mutational spectrum in 48 additional unrelated families of different geographic origin.

Late onset ornithine transcarbamylase deficiency: a case report.

Ornithine transcarbamylase deficiency, an X-linked disorder, is the most common inherited urea cycle defect. Previous reports have documented the existence of several different mutations that can, partly at least, explain the phenotypic variability of the disorder. We describe the only male with T343K mutation, which also is present in his mother.

Novel disease-causing mutations in the dihydropyrimidine dehydrogenase gene interpreted by analysis of the three-dimensional protein structure.

Dihydropyrimidine dehydrogenase (DPD) deficiency is an autosomal recessive disease characterized by thymine-uraciluria in homozygous deficient patients. Cancer patients with a partial deficiency of DPD are at risk of developing severe life-threatening toxicities after the administration of 5-fluorouracil. Thus, identification of novel disease-causing mutations is of the utmost importance to allow screening of patients at risk.
