Background: Calcium deficiency is common in pregnant women and newborn infants. There are few data about the prevalence of calcium deficiency during pregnancy and infancy in Algeria. We assessed calcium status of pregnant women and their neonates in Sidi Bel Abbes, west of Algeria. The current study aimed to determine the prevalence of hypocalcemia in pregnancy and in their new born and to correlate maternal calcium status with neonates' calcium and birth weight.
Introduction: Aluminum (Al) has the potential to be neurotoxic in human and animals, is present everywhere in the environment, many manufactured foods and medicines and is also added to drinking water for purification purposes and tooth paste cosmetic products They accumulate in living organisms and disrupt balances, and accumulate in the body biological systems, causing toxic effects (They may affect the nervous system, kidney, liver, respiratory or other functions). Nervous system is a vulnerable target for toxicants due to critical voltages which must be maintained in the cells and the all responses when voltages reach threshold levels.
Objective This study aimed to expose the impact of aluminum chloride (AlCl3) on brain architecture.
Methods: In our study, twenty healthy female rats were intraperitoneal administered of aluminum chloride (ALCL3) at 10 mg / kg body weight with consecutively for 15 day
Result. The results showed a highly significant reduction in body weight (p<0.0001). This is because aluminum has an anorectic effect contrariwise, there is no significant impact of aluminium exposure has been observed with respect to brain weight and relative brain weight respectively (p<0.912), (p<0.45).
The histological study describes the alterations in the brain marked tissue necrosis and cytoplasmic vacuolations and karyopyknosis of neuronal cells of the brain.
Conclusion; Aluminum is a toxic heavy metal and a ubiquitous environmental pollutant. It can alter the permeability of the blood-brain barrier and enter the brain, severely affecting the functioning of the nervous system.

IntroductionLes léiomyomes ou fibromyomes plus communément dénommés fibromes, sont les tumeurs les plus répandues du tractus génital féminin. Ils affectent 20 à 25% des femmes en activité génitale. Notre étude vise à élucider la réalité de ce type de pathologie dans la région de sidi bel Abbes, nord-ouest d'Algérie.MéthodesA travers une étude rétrospective allant du 1er janvier 2008 au 1 mai 2011 portant sur les patientes opérées pour fibrome au sein de la maternité de Sidi Bel Abbes, nous avons relevé les particularités épidémiologiques et cliniques de cette pathologie.RésultatsAu total 323 cas de fibromes ont été recensés. La tranche d'âge la plus touchée varie de 40 à 44 ans dans une fourchette d'âge comprise entre 20 et 74 ans. 37.83% des patientes étaient nullipares. Une prédominance des patientes dont l'âge de la ménarche est précoce, a été retenue (60.3%). 3% des femmes ont présenté un terrain familial prédisposant. La symptomatologie était dominée par les hémorragies génitales (35%). La majorité des patientes (51.70%) présentaient un utérus polymyomateux dont la localisation des fibromes était principalement corporéale (96%), sous séreuse (43%). Le traitement était conservateur dans 71.82% des cas.ConclusionSur la base des résultats obtenus, la mise au point d'un programme national de sensibilisation et de dépistage précoce, s'impose
