Introduction: Pulmonary agenesis is a rare congenital abnormality defined by the absence of parenchyma, bronchi and pulmonary vessels, frequently associated with other malformations. We describe a case of isolated right pulmonary agenesis diagnosed in the pediatric ward of the Mali Hospital. Clinical case: He was a month-old baby boy, born at term by cesarean section of a well-followed pregnancy. He was not resuscitated. He developed dyspnea after a cold. An emergency chest X-ray revealed a right opaque lung. He was referred to the hospital for the exploration of this opacity. At the entrance, it weighed 3910 g, size: 54 cm and the temperature was 36.9°C. He had a polypnea, an intercostal print. The sounds of the heart were diverted to the right. The rest of the clinical examination was without much particularity. The chest CT scan confirmed the right pulmonary agenesis. Abdominal and cardiac ultrasound was normal. A healing includes oxygenotherapy, serum glucose 10% minding 100 ml/ Kg/day and amoxicillin minding 100 mg/ Kg/day at 3 times by oral way. After 24 hours of treatment, we observed an improvement in dyspnea. On D2,

This paper gives all the two-dimensional membrane models obtained from formal asymptotic analysis of the three-dimensional geometrically exact nonlinear model of a thin elastic shell made with a saint Venant-Kirchhoff material. Therefore, the other models can be quoted as flexural nonlinear ones. The author also gives the formal equations solved by the associated stress tensor and points out that only one of those models leads, by linearization, to the "classical" linear limiting membrane model, whose justification has already been established by a convergence theorem.

The temporal variations of the Gross Primary Productivity (GPP), the Total Ecosystem Respiration (TER) and the Net Ecosystem Exchange (NEE), and their responses to meteorological conditions (e.g. temperature, radiative flux and precipitation) at Lamto, in wet savannah region across C?te d’Ivoire are analyzed using GFED-CAsa and daily meteorological data recorded over the 2008-2015 period. The study shows the links between these carbon fluxes and climate variability at Lamto that is subject to high anthropogenic pressures and seasonal bushfires. The correlative statistics from multiple regression methods were used to assess the different relationships and show how they change in time. The results show important seasonal variability in the Gross Primary Productivity and the Total Ecosystem Respiration mainly associated with the changes in temperature and radiative flux. In addition, the statistical analysis suggests a high correlation between meteorological conditions and the GPP and TER. These climatic conditions may explain 83% and 79% of the variances of GPP and TER respectively. Moreover, the interannual variability of the Net Ecosystem Exchange indicates that around Lamto, in the subhumid savannah, the ecosystem behaves as a carbon sink similar to other West African ecosystems. On the other hand, there is no clear link between the NEE and temperature, radiative flux and precipitation. This lack of connection may suggest a limited response of the NEE interannual dynamics related to the changes in climatic features.

Introduction: The human immunodeficiency virus (HIV) is a pandemic of concern to the World Health Organization. It is all the more worrisome because if not properly managed, it can be responsible for several complications, including abnormal blood counts. These abnormalities may also be related to treatment. Objectives: The main objective of this study is to show that adequate antiretroviral therapy can correct various abnormalities exerted by HIV on patients’ blood counts. The specific objective is to determine all the abnormalities we can see in blood count before and during HIV treatment. Materials and Methods: Our study was conducted in the hematology laboratory and the dermatology departments of the Aristide Le Dantec Hospital and the Institute of Social Hygiene. It took place from December 2009 to October 2011. It is a retrospective descriptive and analytical study involving HIV-positive patients (HIV 1 and 2) and under antiretroviral treatment (at least six months of treatment). We included 110 patients in the study. Blood counts were performed at the hematology laboratory of the Aristide le Dantec hospital using a KX21 automaton. Each patient received three blood counts during the first six months of treatment (M0, M3 and M6). A univariate analysis was performed to determine the profile of the abnormalities of the blood count and the chi 2 test was used and a threshold of p 0.05 was considered significant. Results: The mean age of the patients was 38.6 ± 8.6 years (extremes of 18 and 64 years) with a sex ratio of 0.42 (77 females and 33 males). The prevalence of anemia was 80% (n = 88) at M0, 53, 63% at M3 (n = 59), and 38.20% at M6 (n = 42) (p = 0.02). We noted a favorable evolution with treatment. For the other abnormalities, the evolution was favorable for leukopenia (p = 0.011) and thrombocytopenia (p = 0.007). Conclusion: Our study showed a correction of blood count abnormalities in PLHIV with antiretroviral treatment.

In the present work, the treatment of synthetic waters doped with iron (II) has been studied. The treatment mechanism used in this study is the biological oxidation which consists, in test tubes, of bringing bacteria isolated on Petri dishes into contact with water containing divalent iron (II). These de-ironing bacteria (non-specific bacteria) are used to carry out laboratory biological oxidation experiments on iron (II) under different pH conditions (pH = 3.4 - 3.6, pH = 7.3 - 7.5 and pH = 9.8 - 10) and variable concentration of iron (II). Biological treatment trials included different concentrations of iron during time intervals of a day. Examination of the elimination kinetics of Iron (II) indicates a removal rate of 59.453% for an initial iron concentration in the synthetic solution of 1 mg·L−1 at basic pH (pH = 9.8 - 10). Therefore, the degradation of divalent iron by this method seems to be quite effective, but it should be noted that biological nitrification is impaired by the presence of high iron concentrations above 5 mg·L−1.

Acute panmyelosis with myelofibrosis (APMF) is a subtype of acute myeloid leukemia (AML) classified among the category of “AML, not otherwise specified” in the WHO 2016 classification of hematopoietic tumors. It is a rare, fatal hematological neoplasm that is characterized by acute onset of cytopenias and bone marrow fibrosis in the absence of splenomegaly or fibrosis related morphological changes in the red blood cells. The difficulty of diagnosis and management explains why APMF is rarely reported in Africa. We report here the case of a 30-year-old man who presented with dizziness, palpitations and dyspnea. Diagnosis of APMF was retained on bone marrow histology and immunohistochemistry which showed bone marrow fibrosis and high cellularity with majority of myeloid blast cells. The patient was treated by low dose cytarabine monotherapy 30 mg/m2 per week. At 3 months of treatment, the patient was transfusion-independent, with normalization of hemoglobin and platelets counts. However, the death occurred after 8 months. This case highlights the diagnosis specificity and management of AMPF, knowing the number of potential differential diagnoses and difficulties of its therapeutic management.

Roughly quadrangular, the chiasma presents many morphological variations. The optical chiasm, odd and symmetrical structure of the optical pathways, is a required passage of the axons of neurons for the visual pathways. Any modification of its morphology evokes a pathological process, generally tumoral. The quality of MRI images rivals that of anatomical slices. So the MRI is essential for the study of the chiasma. The aim of this work was to study the morphometry of the optic chiasm in patients addressed for cerebral MRI to the imaging department of the university hospital of the POINT-G, during the period from July 29, to November 30, 2016. All patients who had a normal examination of the optic chiasma, numbering 15, were included in this study. In 86.66% of cases the chiasma had a quadrilateral form. Its average length was 8.73 mm and its average width was 13 mm. The average thickness was 4.13 mm.
