Abstract
BACKGROUND Neisseria meningitidis is one of the most important causes of meningitis and pathogens-associated deaths in developing and developed countries. Effective anti-microbial agents are pivotal to treat and control N. meningitidis infections. The aim of the present study was to systematically review published studies on the antibiotic resistance of N. meningitidis in the last 20 years (2000-2020) in the world. METHODS Published researches were identified through a literature search using reputable databases including PubMed, Scopus, and Web of Science. Finally, 24 studies were included for a random-effects model meta-analysis. RESULTS The overall resistance to most commonly used antibiotics such as ceftriaxone, cefotaxime, ciprofloxacin and rifampin was low, ranging from 1 to 3.4%. However, non-sensitivity to penicillin, as the first-line antibiotic against N. meningitidis, was higher (27.2%). Altogether, the resistance to the first-line antibiotics (except penicillin) is still low indicating these drugs are effective against meningococcal meningitis. We also found a significant gap between MIC and disk diffusion for evaluating resistance to antibiotics in which disk diffusion overestimate the resistance rate. CONCLUSIONS To properly management and prevent the spread of N. miningitidis isolates resistant antibiotics, it is necessary to monitor the pattern of antibiotic susceptibility regionally and globally using the MIC methods.

Abstract
In the Middle East and North Africa (MENA) region, dogs are the main reservoir for rabies. In this region, rabies affects more domestic carnivores (50% of cases) than farm animals (40% of cases). Rabies in large livestock animals, which are infected mainly by dogs, results in economic losses, undermines food safety and poses a risk for humans. In the MENA region, rabies is largely an urban problem, the virus being transmitted to humans by free-roaming dogs, 30% of which are less than one year old. In cities, the density of the free-roaming dog population varies between 0.6 and 1.5 dogs per km2, and almost double this figure in suburban and rural areas, where 80% of canine rabies cases occur. In the Maghreb, the annual average number of confirmed human deaths from rabies is around 47, showing a strong correlation with the number of animal cases declared (approximately 1,442 cases a year). In the Middle East, only a few rabies cases in humans are officially reported, suggesting that rabies cases in humans are grossly underreported. National strategies to control rabies include vaccination, controlling the freeroaming dog population and raising awareness among the human population at risk. Owing to limited resources and poor coordination between the different stakeholders, these strategies are only partially implemented. The Food and Agriculture Organization of the United Nations, in close collaboration with the World Organisation for Animal Health and the World Health Organization, supports countries in formulating and implementing coordinated strategies between the ministries concerned, local authorities and non-governmental organisations.

Abstract
The increasing rate of autoimmunity in recent decades cannot be related to only genetic instabilities and disorders. Diet can directly influence our health. Studies have shown that there is a relationship between nutritional elements and alteration in the immune system. Among immune cells, the function of T lymphocyte is important in directing immune response. T CD4+ cells lead other immune cells to respond to pathogens by secreting cytokines. HIV+ patients, who have largely lost their T CD4+ cells, are susceptible to opportunistic infections, which do not normally affect healthy people. It seems that the metabolism of T cells is critical for their differentiation and their consequent functions. After activation, T cells need to undergo clonal expansion, which is a high energy- consuming process. Studies have shown that specific metabolites deprivation or their excess supply affects T CD4+cells subsets differentiation. Abnormal induction of subsets of T CD4+ cells causes some autoimmunity reactions and hyper-sensitivity as well, which may result from imbalance of diet uptake. In this mini-review, we describe the findings about fatty acids, glucose, amino acids, and vitamins, which are effective in determining the fates of T CD4+ cells. These findings may help us uncover the role of diet in autoimmune diseases.

Abstract
INTRODUCTION Malignancies have been reported to occur with increased frequency in chronic lymphocytic Leukemia (CLL) patients. The aim of this study was to describe which second malignancies occur in patients with CLL, whether these malignancies are related to CLL, its treatment, or both. We also attempt to study factors predicting the development of other malignancies. PATIENTS AND METHODS Between 1995 and 2009, six cases of CLL associated with solid tumor were diagnosed in Hematology Department of Military Hospital of Tunis. The diagnosis of CLL was made by immunophenotyping of peripheral blood circulating B cells, and the diagnosis of solid tumors was made by biopsy with anatomopathological exam and immunohistochemical study. RESULTS The mean age of patients was 71 years. Five patients were male. The CLL was classified Stage A in one case, Stage B in three cases and Stage C in two cases. Two patients had abnormal karyotype. Three patients have not received specific treatment for their CLL. Solid tumors were represented by skin cancer in three cases, lung cancer in two cases and breast cancer in one case. The median time between diagnosis of CLL and that of solid tumor was 53 months. CONCLUSION Patients with CLL have an increased risk of developing a second cancer. Awareness of risk factors could permit early detection.

Abstract
We report an observation of extensive and atypical dermatophytosis to Trichophyton rubrum coexisting with fingernails and tinea manuum candidiasis in a 13-year-old girl presenting inflammatory cutaneous lesions, involvement of scalp, as well as total dystrophic onychomycosis of feet associated with a perionyxis of hands. The results of the mycological examination of specimen showed fungal elements of septate hyphae and pilar parasitism. The fungal culture allowed the diagnosis of certainty of the dermatophytosis to T. rubrum. The therapeutic success of this infection was obtained thanks to the administration of antifungals by oral route.

Abstract
BACKGROUND The aim of the study was to estimate the seroprevalence and risk factors of toxoplasmosis in pregnant women in the department of Annaba, Algeria. METHODS We performed a cross-sectional study with analytical purposes. The study was collaboration between the laboratory of Parasitology-Mycology, Faculty of Medicine of Annaba and Parasite Biology Department at the Pasteur Institute of Algeria. A total of 1028 pregnant women who underwent prenatal diagnosis/visit were included over a period of 4 years from January 2006 to December 2009. Immunoglobulin G and M were assayed, using the microparticle enzyme method. The avidity test was used to determine the date of contamination according to age of pregnancy. Search for the parasite was made by inoculation of the placenta and cord blood in white mice. The study compared mother-to-child serological profiles using Western Blot (WB) IgG and IgM. Direct (not well-cooked meat) and indirect (presence of cat, gardening) indicators were recorded to search for parasite exposure. RESULTS Seroprevalence was 47.8 % (95 % CI: 44.8 to 51.0) and the rate of active toxoplasmosis was 1.1 % (95 % CI 0.6 to 1.8). According to their immune status, this was the first serology for 41 % (CI95 %: 38.0-44.0) of women; 12 % (CI95 %: 10.5-14.6) of primiparous women had only one serology test during their entire pregnancy. Major risk factors were consumption of poorly-cooked meat and exposure to cats. CONCLUSION Toxoplasmosis during pregnancy is a serious issue and an effective prevention program is needed.

Abstract
This paper deals with pole placement PI-state feedback controller design to control an integer order system. The fractional aspect of the control law is introduced by a dynamic state feedback as u(t)=K(p)x(t)+K(I)I(α)(x(t)). The closed loop characteristic polynomial is thus fractional for which the roots are complex to calculate. The proposed method allows us to decompose this polynomial into a first order fractional polynomial and an integer order polynomial of order n-1 (n being the order of the integer system). This new stabilization control algorithm is applied for an inverted pendulum-cart test-bed, and the effectiveness and robustness of the proposed control are examined by experiments.

Abstract
OBJECTIVE Human pheochromocytoma tumor cells express glucagon receptors, and bolus i.v. glucagon injection rapidly increases plasma epinephrine levels, suggesting that glucagon can directly stimulate adrenomedullary secretion. In this study, we tested whether the catecholamine secretory response to glucagon was present in bovine chromaffin cells or exclusive to the tumor cells. DESIGN AND METHODS Adrenomedullary cells were cultured in 24-well plates (10(6) cells per well). After 48-72 hours, wells were incubated for 1-20 minutes with (1) incubation medium (control), (2) catecholamine secretagogues (nicotine or potassium ion), or (3) glucagon (10(-8) to 10(-5) M). After incubation, catecholamine contents in medium and cells were assayed by high-pressure liquid chromatography with electrochemical detection. Fractional release rates of epinephrine, norepinephrine, and dopamine were calculated and compared to controls. Reverse-transcriptase PCR was performed to compare expression of mRNA of the glucagon receptor in chromaffin cells and pheochromocytoma cells. RESULTS Nicotine and potassium evoked time-dependent release of epinephrine, norepinephrine, and dopamine. Glucagon did not affect catecholamine secretion at any concentration. Reverse-transcriptase PCR failed to detect mRNA for glucagon receptor in bovine adrenomedullary cells, but did detect it in human pheochromocytoma cells. CONCLUSIONS In contrast to pheochromocytoma tumor cells, bovine adrenomedullary chromaffin cells do not express the glucagon receptor, and therefore do not secrete catecholamines in response to glucagon.

Abstract
Objectives To compare the antiviral efficacy of a salvage therapy combining lopinavir and amprenavir with 200 mg/d or 400 mg/d ritonavir, together with nucleoside reverse transcriptase inhibitors, over a 26-week period in HIV-infected patients in whom multiple anti-retroviral regimens had failed. Design Phase IIb, randomized, open-label, multicentre trial. Patients were eligible if they had <500 CD4+ cells/mm3 and >4 log10 copies/ml HIV-RNA after treatment with at least two protease inhibitors (PIs) and one non-nucleoside reverse transcriptase inhibitor. Results At baseline ( n=37), the median CD4+ cell count was 207/mm3 and the median plasma HIV-1 RNA level was 4.7 log10 copies/ml; the median number of PI mutations was seven and the median decrease in phenotypic susceptibility to lopinavir and amprenavir was 9.7 and 2.6, respectively. The mean number of antiretrovirals received prior to randomization was 7.7. The fall in the median HIV-1 RNA level at week 26 was -1.4 log10 copies/ml in the 200 mg/d ritonavir group and -2.5 log10 copies/ml in the 400 mg/d group ( P=0.02). Viral load fell below 50 copies/ml in 32% and 61% of patients, respectively ( P=0.07). After adjustment for the ritonavir dose, a smaller number of PI mutations was the only baseline characteristic associated with a better virological response at week 26. Amprenavir concentrations were significantly lower in presence of lopinavir. The lopinavir inhibitory quotient at week 6 correlated weakly with the change in the HIV-RNA level at week 26. Conclusion Combination of amprenavir, lopinavir and 400 mg/d ritonavir shows significant virological efficacy without increased toxicity in HIV-infected patients in whom multiple antiretroviral regimens have failed.

Abstract
Pneumocystis carinii pneumonia (PCP) is a severe and dangerous infection which afflicts patients with immune deficiency, particularly those with AIDS. This pathology isn't well known in Algeria. The aim of the present study is a contribution to make this disease more known in the algerian AIDS patients. It has focused on the research and the identification of P. carinii in the expectorations and in the bronchalveolar lavage (BAL) fluids of 14 patients with respiratory troubles: 13 were AIDS cases and one with an iatrogenic immune deficiency. 3 of these patients were women and the rest were men. Their average age was 35.

Abstract
The influence of horse antihuman thymocyte globulin (ATG) on renal allograft survival was assayed between March 1977 and August 1978. Fifty consecutive patients were randomly assigned to the treatment or the control group. Patients in both groups received azathioprine and prednisolone. ATG was added in the experimental group. The daily dosage was such as to maintain the rosette-forming cell (RFC) level at 10% of baseline values. The number of renal failure episodes (RFE's)was significantly lower in the experimental group during the period (1 month) ATG was given than it was in the control group during that same period of time. Two years after transplantation, kidney survival was 79% in the ATG group and 52% in the control group. The amount of steroids necessary to control RFE's was significantly lower in the ATG group. The dosages of ATG used in the experimental group were relatively small (average daily dose, 3.08 +/- 0.26 mg/kg of body wt), and adverse reactions were mild. Blood tolerance was excellent. T-cell monitoring thus appears to be an effective method in evaluating the daily dosage of ATG.
