Pikiliwè Department of hematology Campus Teaching Hospital University of Lomé Lomé Togo Department of Pediatrics Sylvanus Olympio Teaching Hospital University of Lomé Lomé Togo National Center of Research and Treatement of Sickle Cell Disease Patients (CNRSD) Lomé Togo Department of hematology Sylvanus Olympio Teaching Hospital University of Lomé Lomé Togo

Background: hemopathies were rarely observed in major sickle cell disease patients some thirty years ago, probably due to the high mortality rate among the latter as a result of progressive complications. Thanks to advances in the management of sickle cell disease, patients' life expectancy has increased considerably, exposing them more frequently to neoplasia, including hematological malignancies. The increased risk of leukemogenesis is multifactorial and linked to the pathophysiological mechanisms of the clinical manifestations of sickle cell disease. Study Setting: The clinical haematology department of campus teaching hospital and the paediatric onco-haematology unit of Sylvanus Olympio teaching hospital in Lomé were used as study settings. Observations: Four hematologic malignancies were collected in a cohort of 5847 major sickle cell syndromes. The median age of the patients was 31.25 years (extremes: 14 and 58 years) and they were predominantly female (sex ratio m/F = 0.25). Two were on background therapy with hydroxyurea. Among the four patients, there were two cases of acute lymphocytic leukemia, including ALL3 in a 58-year-old SS woman and T-ALL2 in a 12-year-old sc. Then, a case of lymphocytic lymphoma in a 20-year-old SS man was reported and finally a case of chronic myelocytic leukemia in a 33-year-old woman of Sβ+ thalassaemia phenotype. Conclusion: To further report this coexistence, it is therefore essential to systematically consider hematological malignancies during major sickle cell syndromes even if there are similarities in the symptomatology of these two serious pathological situations.

The rarity of such aecidents and the fact that no grave complications arose from serious injury to such important structures warrants, we think, the report of this case. Admission notes. A patient, T. F., hospital number 6716, male Chinese, twenty four years of age, married, helper in a bean milk shop was admitted to the Chengtu Eye, Ear, Nose and Throat hospital at eight a. m. on the eighth of April, 1936. At four a. m. the patient had been fighting with a, fellow worker who struck him with a chop-stick which entered the lower lid of the left eye at its inner corner. The chop-stick was breken off at a point 2.2

For a bounded operator T acting on an infinite dimensional separable hilbert space h, we prove the following assertions：（i） If T or T＊ ∈ sc, then generalized a- Browder＇s theorem holds for f（T） for every f ∈ hol（σ（T））. （ii） If T or T＊ ∈ hC has topological uniform descent at all λ ∈ iso（a（T））, then generalized Weyl＇s theorem holds for f（T） for every f ∈ hol（σ（T））. （iii） If T ∈ hC has topological uniform descent at all λ ∈（T）, then T satisfies generalized Weyl＇s theorem. （iv） Let T ∈ hC. If T satisfies the growth condition Gd（d 〉 1）, then generalized Weyl＇s theorem holds for f（T） for every f ∈ hol（σ（T））. （v） If T ∈ sc, then, f（OssF＋（T）） = aSBF＋（f（T）） for all f ∈ hol（σ（T））. （vi） Let T be a-isoloid such that T＊ ∈ hC. If T - AI has finite ascent at every A ∈ Eσ（T） and if F is of finite rank on hsuch that TF = FT, then T ∈ F obeys generalized a-Weyl＇s theorem.

The structural vibrational, thermodynamical, and optical properties of potentially technologically important, weakly coupled mAX compound, sc2 Al C are calculated using density functional theory(DFT). The structural properties of scAlC are compared with the results reported earlier. The vibrational, thermodynamical, and optical properties are theoretically estimated for the first time. The phonon dispersion curve is calculated and the dynamical stability of this compound is investigated. The optical and acoustic modes are observed clearly. We calculate the helmholtz free energy(F), internal energy(E), entropy(S), and specific heat capacity(Cv) from the phonon density of states. Various optical parameters are also calculated. The reflectance spectrum shows that this compound has the potential to be used as an efficient solar reflector.
