A case-control study was conducted 1) to determine whether maternal prenatal drug consumption increases the risk of neuroblastoma in the child and, if so, 2) to see if the size of the risk depends on whether the case is inherited or sporadic. Mothers of children with newly diagnosed neuroblastoma (n = 101) were compared with mothers of children newly diagnosed with other forms of childhood cancer (n = 690). Cases and controls were selected from the population of childhood cancer patients at St. Jude Children's Research Hospital, Memphis, Tennessee, between 1979 and 1986. The patients' mothers were interviewed to ascertain their prenatal medication, alcohol, and tobacco consumption patterns. Unconditional logistic regression models were used to adjust for maternal age at birth, patient age at diagnosis, race, social class, exposure to x-ray, miscarriage, and other confounding variables. Adjusted odds ratios were estimated for the total sample and for subgroups that had a higher probability of containing inherited cases. Drugs associated with neuroblastoma case status include diuretics for hypertension (odds ratio (OR) = 4.1, 95 percent confidence interval (CI) 1.0-16.9), tranquilizers (OR = 2.1, 95 percent CI 1.1-4.3), nonprescription pain relievers (OR = 1.9, 95 percent CI 1.1-3.1), and cigarettes (OR = 1.9, 95 percent CI 1.1-3.2). The odds ratios for maternal prenatal drug consumption for the group with inherited cases and the total sample were approximately the same. This equality is inconsistent with predictors based on Knudson's two-stage model of carcinogenesis.

Neuroblastomas are the fourth most common malignancy of childhood and account for most adrenal tumors in children. However, they are rarely reported in adults. We present herein an extremely rare case of adrenal neuroblastoma occurring in a 25-year-old woman during her first trimester of pregnancy. She had a spontaneous abortion secondary to chorioamnionitis and she was operated on for an "incidentaloma." Her tumor was curatively resected. She presented with right lower quadrant abdominal pain 26 months after her operation and there was evidence of local tumor recurrence without metastasis. Adult adrenal neuroblastoma is an uncommon malignancy and, to our knowledge, there was no case of this tumor occurring in pregnancy ever described in the English literature. The case presentation is followed by a general discussion with an emphasis on the diagnosis, treatment, and follow-up of neuroblastoma and its association with pregnancy.

We propose a biochemical mechanism for celiac disease and non-celiac gluten sensitivity that may rationalize many of the extradigestive disorders not explained by the current immunogenetic model. Our hypothesis is based on the homology between the 33-mer gliadin peptide and a component of the NMDA glutamate receptor ion channel - the human GRINA protein - using BLASTP software. Based on this homology the 33-mer may act as a natural antagonist interfering with the normal interactions of GRINA and its partners. The theory is supported by numerous independent data from the literature, and provides a mechanistic link with otherwise unrelated disorders, such as cleft lip and palate, thyroid dysfunction, restless legs syndrome, depression, ataxia, hearing loss, fibromyalgia, dermatitis herpetiformis, schizophrenia, toxoplasmosis, anemia, osteopenia, Fabry disease, Barret's adenocarcinoma, neuroblastoma, urinary incontinence, recurrent miscarriage, cardiac anomalies, reduced risk of breast cancer, stiff person syndrome, etc. The hypothesis also anticipates better animal models, and has the potential to open new avenues of research.
