Congenital anomalies are already the second cause of infant mortality in Brazil, as in many other middle-income countries in Latin America. Birth defects are a result of both genetic and environmental factors, but a multifactorial etiology has been more frequently observed. Here, we address the environmental causes of birth defects - or teratogens - as a public health issue and present their mechanisms of action, categories and their respective maternal-fetal deleterious effects. We also present a survey from 2008 to 2013 of Brazilian cases involving congenital anomalies (annual average of 20,205), fetal deaths (annual average of 1,530), infant hospitalizations (annual average of 82,452), number of deaths of hospitalized infants (annual average of 2,175), and the average cost of hospitalizations (annual cost of $7,758)...

Thalidomide and its derivatives lenalidomide and pomalidomide (IMiDs) are effective treatments of haematologic malignancies. It was shown that IMiDs impart gain-of-function properties to the CUL4-RBX1-DDB1-CRBN (CRL4(CRBN)) ubiquitin ligase that enable binding, ubiquitination and degradation of key therapeutic targets such as IKZF1, IKZF3 and CSNK1A1. While these substrates have been implicated as efficacy targets in multiple myeloma (MM) and 5q deletion associated myelodysplastic syndrome (del(5q)-MDS), other targets likely exist...

Thalidomide, previously banned owing to the issues of teratogenicity is being used and tested for a variety of dermatological and non dermatological conditions. The drug has been approved for the management of ENL and Multiple myeloma. The drug is commonly known to produce adverse effects like peripheral neuropathy and constipation. Deep vein thrombosis (DVT) is one of the serious adverse effects seen with thalidomide use, especially in malignancies and is relatively uncommon in non cancer settings like ENL...

Evidence has been presented for auto-induced human cytochrome P450 3A enzyme involvement in the teratogenicity and clinical outcome of thalidomide due to oxidation to 5-hydroxythalidomide and subsequent metabolic activation in livers. In this study, more relevant human placenta preparations and placental BeWo cells showed low but detectable P450 3A4/5 mRNA expression and drug oxidation activities. Human placental microsomal fractions from three subjects showed detectable midazolam 1´- and 4-hydroxylation and thalidomide 5-hydroxylation activities...

BACKGROUND: Discoid lupus erythematosus (DLE) is a chronic form of cutaneous lupus, which can cause scarring. Many drugs have been used to treat this disease and some (such as thalidomide, cyclophosphamide and azathioprine) are potentially toxic. This is an update of a Cochrane Review first published in 2000, and previously updated in 2009. We wanted to update the review to assess whether any new information was available to treat DLE, as we were still unsure of the effectiveness of available drugs and how to select the most appropriate treatment for an individual with DLE...

Congenital heart disease is the leading cause of death in the first year of life. Mutations only in few genes have been linked to some cases of CHD. Thalidomide was used by pregnant women for morning sickness but was removed from the market because it caused severe malformations including CHDs. We used both in silico docking software, and in vitro molecular and biochemical methods to document a novel interaction involving Thalidomide, TBX5, and HAND2. Thalidomide binds readily to TBX5 through amino acids R81, R82, and K226 all implicated in DNA binding...

Multiple myeloma (MM) is a clonal proliferation of malignant plasma cells in the bone marrow (BM) that secretes monoclonal paraproteins in the blood serum and urine. Bone marrow MM cells can invade and damage the functions of other tissues and organs, such as the lungs, spleen, liver, pancreas, kidneys and lymph nodes. However, the invasion of MM cells primarily located in the BM to the anterior mediastinum at the site of the thymus is an extremely rare event. The current study reports the case of a 53-year-old female who presented with MM with involvement of the anterior mediastinum...

Multiple myeloma is a plasma cell dyscrasia accounting for 10% of haematologic malignancies. Lenalidomide is an immunomodulatory drug analogous to thalidomide that is approved for use in patients with myelodysplastic syndrome, and in combination with dexamethasone for refractory or relapsed multiple myeloma. Lenalidomide is preferred to thalidomide because of reduced toxicity, and pulmonary side effects are considered rare. We present, to our knowledge, an unusual and first reported case of a patient with relapsed multiple myeloma who received lenalidomide after autologous stem cell transplant, then developed eosinophilic pneumonia presenting as dyspnoea, peripheral eosinophilia, and bilateral pulmonary opacities...

Multiple myeloma (MM) is a hematologic malignancy characterized by proliferation of malignant plasma cells. patient outcome has improved markedly over the last decades due to the introduction of novel therapeutic agents such as bortezomib, thalidomide and lenalidomide. However, MM still remains largely incurable and patients eventually become refractory to available treatments. To address this unmet medical need, a variety of new molecules are currently being developed in preclinical models and/or are being investigated in clinical studies...

Psychiatric and personality disorders have been extensively documented in patients with systemic lupus erythematosus (SLE). However, the prevalence of personality disorders in skin-restricted lupus (SRL) patients remains unknown. The aim of this study was to assess the prevalence of personality disorders in SRL outpatients and to examine the associated factors. We evaluated 60 SRL outpatients and 118 controls matched for sex, age and education level. On the basis of the Personality Diagnostic Questionnaire 4+, 38% of patients vs 20 % of controls fulfilled the criteria for at least one personality disorder (OR 2...

Drug resistance of multiple myeloma(MM) has become more and more common, and greatly decreased the survival rate of these patients. The occurence of drug-resistance involves in many factors such as bone marrow microenveronment, tumor cell self-metabolism, cytokines, specific targets and so on. In this review, the potential mechanisms of resistance to glucocorticoid/proteasome inhibitor/immunomodulatory druges are briefly expounded in the aspect of tumor cell self-metabolism, including the changes of heat slock protein expression, mRNA expression, related cytokine levels and down-regulation of thalidomid-effecting site CRBN expression...
