Progressive acquired lymphangioma: report of a case and review of the literature

We present 2-year-old patient with a allopecia lesions in scalp, and clinique diagnostic of Cutis Aplasia. The anatomopathologic study have diagnosed the lesions as Acquired Progressive Lymphangioma (APL). Is a rare vascular tumour that has a tendency to appear in childhood an to progress slowly over the years. It could present as a solitary erythematous macule or plaque and a simple excision is usually curative. Our patient is the youngest reported in the literature.     

Infants born to narcotic dependent mothers: Physical growth patterns in the first 12 months of life

Objectives: To describe the physical growth patterns of infants born to narcotic dependent mothers (INDM) over a 12 months period and, if possible, to relate the growth to drug taking patterns during pregnancy.
Methodology: The growth of a cohort of 43 INDM was measured during the first 12 months of life. Weight and length measurements were compared with percentile charts and converted to Z scores. Questionnaire data about drug taking practices, demographic variables and the neonatal period (including withdrawal scores) were obtained.
Results: Twenty-four (55.8%) of INDM had evidence of neonatal drug withdrawal requiring treatment with phenobarbitone. At birth, Z scores for weight and length indicated relative intrauterine growth retardation. By 12 months, there had been some catch up growth, but Z scores for weight and length were still below zero. Persistent weight retardation at 12 months was correlated with methadone dosage during pregnancy, but not the need for phenobarbitone therapy.
Conclusions: The growth patterns of INDM in the first 12 months of life indicated that at birth there was evidence of intrauterine growth retardation, but by 12 months the growth was little different from the rest of the community. There appears to be some influence of narcotic agents taken while pregnant on subsequent growth of INDM.     

Identification of differentially expressed genes in aflatoxin B1- treated cultured primary rat hepatocytes and Fischer 344 rats

Aflatoxin B1 (AFB1), a mutagen and hepatocarcinogen in rats and humans, is a contaminant of the human food supply, particularly in parts of Africa and Asia. AFB1-induced changes in gene expression may play a part in the development of the toxic, immunosuppressive and carcinogenic properties of this fungal metabolite. An understanding of the-role of AFB1 in modulating gene regulation should provide insight regarding mechanisms of AFB1-induced carcinogenesis. We used three PCR- based subtractive techniques to identify AFB1-responsive genes in cultured primary rat hepatocyte RNA: differential display PCR (DD-PCR), representational difference analysis (RDA) and suppression subtractive hybridization (SSH). Each of the three techniques identified AFB1- responsive genes, although no individual cDNA was isolated by more than one technique. Nine cDNAs isolated using DD-PCR, RDA or SSH were found to represent eight genes that are differentially expressed as a result of AFB1 exposure. Genes whose mRNA levels were increased in cultured primary rat hepatocytes after AFB1 treatment were corticosteroid binding globulin (CBG), cytochrome P450 4F1 (CYP4F1), alpha-2 microglobulin, C4b-binding protein (C4BP), serum amyloid A-2 and glutathione S-transferase Yb2 (GST). Transferrin and a small CYP3A-like cDNA had reduced mRNA levels after AFB1 exposure. Full-length CYP3A mRNA levels were increased. When liver RNA from AFB1-treated male F344 rats was evaluated for transferrin, CBG, GST, CYP3A and CYP4F1 expression, a decrease in transferrin mRNA and an increase in CBG, GST, CYP3A and CYP4F1 mRNA levels was also seen. Analysis of the potential function of these genes in maintaining cellular homeostasis suggests that their differential expression could contribute to the toxicity associated with AFB1 exposure.      

Axillary hibernoma: an unusual soft tissue tumor

Hibernomas are rare soft tissue tumors of brown fat differentiation. A case of a large axillary hibernoma, along with a review of its pathology, is presented. This tumor matches the largest hibernoma in the literature and is the largest in an axillary site.     

Análisis coste-efectividad de samario-153 (Quadramet®) en el tratamiento del dolor en pacientes con cáncer de próstata y metástasis óseas

Objective. To evaluate the cost-effectiveness of samarium [¹⁵³Sm-EDTMP] (Quadramet®) compared to conventional therapy in the treatment of pain in patients with prostate cancer and bone metastases. Method. A decision tree model for the treatment of bone pain due to metastases was adapted to the Spanish context. The model represents the standard treatment patterns in Spain for the study population. The time-course of the model is 4 months and it computes an estimate for the cost of pain control per patient. The effectiveness data for the model derive from a randomised trial. The current treatment patterns have been established according to the consensus opinions of a group of medical experts. Results. The cost of pain control per patient is ? 12,515.39 for conventional therapy and ? 5,595.52 for samarium-153 (Quadramet®) therapy. The incremental cost-effectiveness analysis shows that samarium-153 (Quadramet®) is a dominant therapy. It presents lower costs and higher efficacy than the conventional strategy. The sensitivity analyses showed these results to be robust. Conclusion. Samarium-153 (Quadramet®) is costeffective in treating pain in patients with prostate cancer and bone metastases.     

Hydration status,body composition,and anxiety status in aeronautical military personnel from Spain: a cross-sectional study

Background: An adequate hydration status is critical to ensure efficiency during mental and physical activities.Our goal was to assess the hydration status of a Spanish group of aeronautical military men and to determine the association of hydration status with body composition and anxiety.Methods: A total of 188 men were evaluated through a validated hydration questionnaire, anthropometric and biochemical parameters, and an anxiety questionnaire. Based on these methods, the criteria of hydratio...
