Dual-wavelength micro-resonator combining photonic crystal membrane and Fabry-Perot cavity.

We propose a novel system of dual-wavelength micro-cavity based on the coupling between a photonic crystal membrane (PCM); operating at the Γ- point of the Brillouin zone, with a Fabry-Perot vertical cavity (FP). The optical coupling, which can be adjusted by the overlap between both optical modes, leads to the generation of two hybrid modes separated by a frequency difference which can be tuned using micro-opto-electromechanical structures. The proposed dual-wavelength micro-cavity is attractive for application where dual-mode behaviour is desirable as dual-lasing, frequency conversion.

[Diluted injectable quinine in the intramuscular and intrarectal route: comparative efficacity and tolerance in malaria treatment for children ].

The intramuscular (i.m.) route is generally used for treatment of childhood falciparum malaria in outlying health care units in Togo.

[Treatment of cerebral malaria in African children by intravenous quinine: comparison of a loading dose regimen to a regimen without a loading dose].

Objective: To compare in a randomized study the efficacy and the toxicity of the new WHO intravenous quinine treatment of cerebral malaria including a loading dose regimen to a regimen without loading dose.

Patients And Methods: Seventy-two children eight months to 15 years of age with cerebral malaria were included. Quinine formiate was administered to a group of 35 patients in an initial loading dose of 20 mg salt/kg (equivalent to 17.

Priapism in sickle cell anemia in Togo: prevalence and knowledge of this complication.

Prevalence of priapism and knowledge on this disease was assessed by interviewing a group of 114 sickle cell anemia patients, 5 years and older, considered to be genotypically homogenous (Benin or #19 haplotype). Prevalence of priapism in homozygous sickle cell patients was 26.3% (30/114) and that of the control group of subjects with Hb AA was 2% (2/102) (the difference was very significant: p = 5.

[Upper arm circumference reference values for children aged 1 to 36 months in Lome (Togo)].

Background: Mid-upper-arm circumference (MUAC) is widely used as a nutritional status index for children. The aim of our study was to construct MUAC-for-age curves for well-fed 1-36-month-old children of a developing country and to compare them with the WHO reference charts based on samples of American children.

Population And Methods: Five thousand thirty-eight boys and 4,972 girls aged 1-36 months were recruited cross-sectionally from 1994 to 1997.
