Abstract: The main objective of this study was to analyze the effects of sex, ovariectomy (Ovx) and orchidectomy (Orx) on antidepressant and anxiolytic effect of melatonin in forced swimming test, open field test and elevated plus maze test. Initially, 4 mg/kg of melatonin was daily administered, at 4:00 pm, to intact male and female rats during 8 weeks. Our results have shown that the effect of chronic injection of Mel is sex dependent in the three behaviors tests. Females rats have responded better than males in behavior test study after administration of melatonin, this difference between the sexes may be related to the action of sex hormones (androgens and estrogens) on behavior in males as well as in females. Secondly, to determine the possible interaction between Melatonin and steroid hormones, Ovx/sham female received Mel at dose of 4mg/kg alone or NaCl (0.9%) alone, and Orx/sham male received Mel at dose of 4 mg/kg alone or NaCl (0.9%) alone daily and during 8 weeks of treatment at 4:00 pm. All animals were tested in the open-field test, elevated plus maze test for anxiety behavior study, and forced swimming test for depression behavior study. Results revealed that Mel exerts an anxiolytic and antidepressant effects in the orchidectomized males and in intact females, confirming that the suppression of androgens by orchidectomy improved anxiolytic and antidepressant effects of melatonin in males. However in females, the suppression of estrogen by ovariectomy masked the antidepressant and anxiolytic effects of melatonin. Our results confirmed that the antidepressant and anxiolytic effects of melatonin are linked to sex hormones.

Abstract: The main objective of this work was to 1) study the influence of endogenous melatonin (Mel) abolishment via pinealectomy and 2) explore exogenous Mel effect on anxiety-like and depressive-like behavior in male and female rats. Rats were shamoperated (Sh) or pinealectomized (Px) and following subgroups were selected 1) Px/NaCl (0.9%) and Sh/NaCl (0.9%) : rats injected subcutaneously, once daily for 8 weeks, with saline solution NaCl (0.9%) as vehicle; 2) Px/Mel (4 mg/Kg) and Sh/Mel (4 mg/Kg): Rats similarly injected with 4 mg/Kg of Mel. All animals were housed under a photoperiod of (LD:16/8). After different treatments animals were tested in the open-field test (OFT), elevated plus maze test (EPM) to determine anxiety-like behavior, and forced swimming test (FST) to evaluate depressive-like level. Our results revealed that level of anxiety-like and depressive-like behavior are significantly higher in Px/NaCl (0.9%) when compared to Sh/NaCl (0.9%) group, suggesting that pinelectomy induced an anxiogenic and depressant effects. The Px effects would be due to the absence of endogenous Mel synthesis and release. Additionally, we clearly demonstrated that the level of anxiety-like and depressive-like behavior are higher in Px/Mel (4 mg/Kg) and Sh/Mel when compared respectively to Px/NaCl (4 mg/Kg) and Sh/NaCl groups suggesting an anxiolytic and antidepressant effects of exogenous Mel. Behavioral responses were sex dependent since the difference between females and males, especially, after melatonin administration, were statistically significant. These experiments provide evidence that pinealectomy and Mel regulated emotionally behavior in male and female rats.

Abstract: The aim of this study was to determine the effect of pharmacological doses of melatonin (MEL) and L-tryptophan (L-TRP) on depression-like behavior in female rats submitted to the forced swimming test (FST) after 2, 4, 6 or 8 weeks of treatment. This will allow exploring the different mechanisms of L-TRP actions particularly that due to its conversion into MEL. For this purpose, four groups of 24 rats each were constituted; (Group 1: Control): received saline solution NaCl (0.9%), (Group 2: MEL4): received 4 mg/Kg of MEL, (Group 3: L-TRP4): received 4 mg/Kg of L-TRP and (Group 4: L-TRP20): received 20 mg/Kg of L-TRP. Animals of each group were distributed on 4 subgroups of 6 rats submitted to different time treatments. The duration of immobility (TIM) and struggling period (TST) of rats in FST were measured after 2, 4, 6 and 8 weeks of drug treatment and the effects of MEL and L-TRP were compared. Chronical administration of different doses of MEL or L-TRP failed to induce any anti-depressant activity in rats subjected to FST after 2 weeks of treatment. However, after 4 weeks, daily administration of MEL at 4 mg/Kg significantly reduced the immobility period and enhanced struggling time. After 6 weeks, MEL at 4 mg/Kg and L-TRP at 20 mg/Kg were both effective in reducing immobility and increasing struggling movement, their effects being statistically comparable. All treatments were able to significantly reduce immobility time and increase struggling duration after 8 weeks, but L-TRP at 4 mg/Kg was less

Abstract: Two new quinoxalinone derivatives have been synthesized adopting the HONG method, and investigated for some neuropharmacological effects (anxiety- and depressive-like responses) in rats. The present experiment sought to determine whether treatment with these compounds produces changes in affective responses. We found that the chronic injection of 6-nitro-2(1H)-quinoxalinone (NQu) showed obvious anxiolytic- and antidepressant-like effects, respectively, measured in the behavioral tests of Elevated Plus Maze (EPM) and Forced Swim Test (FST). At the dose of 30 mg/kg, NQu showed a comparative anxiolytic-like effect in rats as diazepam (Dz) (1 mg/kg), and a comparative antidepressant effect as clomipramine (Clmp) (2 mg/kg; i.p). The 2(1H)-quinoxalinone (Qu) significantly reduced depressive-like responses as evaluated in FST, whereas no anxiolytic-like effect was found as measured by open field test (OF). Additionally, the locomotor activity levels were unaffected by treatment as measured by OF and EPM.

Abstract: Renal cell carcinoma (RCC) is known as a highly aggressive malignancy with frequent metastasis that the major sites being lungs, lymphatic ganglions, bones, liver and brain. Cutaneous metastasis is uncommon with only a few reported cases in the literature. We report a case of a women patient aged 49 years old with RCC who underwent nephrectomy and 8 months previously, she consulted the dermatological service due to the development of recent skin lesions that had been diagnosed as cutaneous metastasis of her RCC. The treatment has associated surgical excision and systemic therapy based on sunitinib.

Abstract: Recent studies have shown the importance of the GABA-ergic transmission in the pathophysiology of anxiety and depressive disorders in humans. Our present study aims to investigate the interaction of melatonin (MEL) with this system by exploring the effects of MEL with or without a facilitator of GABA-ergic neurotransmission, diazepam (DZ) on the levels of depression and anxiety in Wistar rats. For this purpose, different doses of MEL (2, 4 or 16 mg/kg) or DZ (2 mg/kg) are subchronically administered during 15 days. After pharmacological treatments, anxiety levels are evaluated in behavioral tests of Open Field (OFT) and elevated plus maze (EPM) and depression levels are evaluated by the forced swim test (FST). The results showed that MEL produces anxiolytic-like and antidepressant-like effects in a dose-dependent manner; the maximum effect was obtained at a dose of 16 mg/kg. However, a dose of 4 mg/kg is necessary to induce an effect. The effect of MEL and DZ reported in this study concerns selective modulation of behavioral anxiety and depression since locomotor activity assessed by the OFT and EPM was not affected. The subchronic injection of MEL at 4 mg/kg, DZ at 2 mg/kg or the two combined molecules also induces also anxiety-like and antidepressant-like behavior. In addition, a potentiating effect between MEL and DZ was observed. These effects suggest that psychopharmacological actions of MEL are due, at least in part, to its ability to improve the central GABA-ergic transmission.

Abstract:

Background: Several epidemiological studies have been carried to identify the risk factors for developing breast cancer. The aim of this study was to evaluate the risk factors associated with breast cancer in different age groups in the Moroccan women and to determine susceptible and protective factors. Methods: This was?a case control study?including 400 women with breast cancer and 400 controls of the National Institute of Oncology Sidi Mohamed Ben Abdallah, Rabat, Morocco from 2008 to 2010. These women were interviewed for epidemiological information and risk factor for breast cancer. Results: Early age at menarche, late menopause, oral contraceptive and family history with first degree were positively associated with breast cancer in all the series and in the age group between 22 and 34 years. In the age group between 44 and 34 years, a risk of breast cancer was associated only with a family history of breast cancer. In the age group of 45 years or older, the factors which seem to influence a breast cancer are: late menopause, oral contraceptive and family history in the first degree. In contrast, early childbearing, multiparity and lactation were negatively associated with breast cancer. Conclusion: This study is rather in favour of positive association between hormonal factors and breast cancer, and confirms the protective role of multiparity and lactation.

Abstract: Background: Pregnancy is typically accompanied by an increase of micronutrient requirements in general and especially iron. This increased need may be an additional risk factor for developing anemia. Purpose of the study: The aim of this study is to provide data on the prevalence of anemia of pregnancy in the maternity ward of the regional hospital in the city of Temara, and examine risk factors that may expose women to anemia during pregnancy. Materiel and Methods: A prospective cross-sectional study of a year was conducted to the hospital Sidi Lahcen in the city of Temara. Sociodemographic and nutritional data were collected through a questionnaire, obstetric and medical histories of women in labor and the results of biological tests were recorded from the patient obstetric file. Results: Among the 849 women surveyed, 690 (82%) had performed a blood count, and among these 117 (16.8%) were found anemic, with the following proportions: 57.6% had mild anemia, 41.5% had moderate anemia and a minority (0.8%) had severe anemia. The pregnant women aged over 35 years were the most exposed to anemia during pregnancy (47%) compared with younger women (p < 0.001). Women who had a history of anemia aside from pregnancy and those who had anemia in earlier pregnancies were more prone to developing anemia in the current pregnancy with a statistically significant difference (p < 0.001). The number of pregnancies, number of previous abortions and place of residence had no influence on the occurrence of anemia of pregnancy. The consumption of fortified flour with iron and vitamins as well as consuming iron rich foods was not a protective factor against the development of anemia of pregnancy. Tea consumption near the meal was not a factor exposing to anemia during pregnancy. Conclusion: Anemia is a public health problem in Morocco. Evidence from our study emphasizes the need to implement educational programs to improve the nutritional knowledge and sensitization of women.

Abstract: Background: The practice of exclusive breastfeeding (EB) in Morocco has witnessed a worrying decline in recent decades, contrary to the recommendations of the World Health Organization (WHO) which advocates it during the first six months as a significant public health tool. The present study aims to assess the impact of educational materials on mothers’ behaviour with regard to keeping up EB as long as six months, at least. Methods: This is a cohort study with a prospective collection of data over a period of one year, through a questionnaire-based survey of 500 women who delivered at the Souissi Maternity Hospital in Rabat. The subjects were divided into an intervention group sensitized, during the medical visit, by means of information delivered orally about breastfeeding and a booklet containing instructions on breastfeeding management and the benefits of EB, especially when extended for the first six months; and a control group attending the same operation with no awareness-rising through educational materials. To assess EB rates, the subjects had been followed for six months through telephone. Results: 372 women who delivered were followed, 194 from the intervention group and 178 from the control group. The remaining 128 women not followed were lost sight of. A higher percentage of mothers in the intervention group exclusively breastfed their babies up to the age of six months compared to the control group, 55.2% against 38.8% (p = 0.002). The main reason produced by most mothers who ceased to exclusively breastfeed their babies is milk insufficiency. Conclusion: The postnatal nutritional education strategy based

Abstract:

Multiple myeloma, a disease of elderly, is extremely rare in those about 30 years of age. A patient with MM diagnosed at age 27 is described. He was a male with a four-month history of back pain and later, hemurus and tibia pain persisting despite NSAIDS. X-rays had shown lytic lesions on lateral radiograph of the skull and the humerus. His ESR was 120 mm. Serum calcium was 125 mg/l and glomerular filtration rate at 25 ml/min. There was a beta2 peak in the serum protein electrophoresis. The Immunohistochemical examination demonstrated a strong reaction for the Lambda light chain in all tumor cells. Bence Jones protein was present in urine. Bone marrow biopsy confirmed the diagnosis of multiple myeloma. Our patient was treated with dexamethasone, zoledronic acid, cyclophosphamide and thalidomide with good evolution. Actually, he was proposed for stem cell transplantation. This report illustrated that multiple myeloma should be even evoked in young patients.
