11. Highly selective 1.55 µm InP/air gap micromachined Fabry-Perot filter for optical communications

Author

Spisser, A., Ledantec, R., Seassal, C., Leclercq, J.L., Benyattou, T., Rondi, D., Blondeau, R., Guillot, G., and Viktorovitch, P.

Abstract

The authors report a highly selective and tunable optical filter at 1.55 µm using a Fabry-Perot resonator with micromachined InP-air gap distributed Bragg reflectors. The resonance full width half maximum, as measured by micro-reflectivity experiments, is close to 0.4 nm (around 1.55 µm) and is compatible with wavelength division multiplexing specifications for optical telecommunications.

13. Brainstem anaesthesia after peribulbar anaesthesia

Author

Boret, H., Petit, D., Ledantec, P., and Bénéfice, S.

Subjects
*BRAIN stem, *ANESTHESIA, *ARTIFICIAL respiration, *AIR conditioning
Abstract

We report a case of pupilloplasty under peribulbar anaesthesia complicated by a brainstem anaesthesia requiring tracheal intubation and mechanical ventilation. Immediate outcome was good. We discuss the different mechanisms of this complication. The subarachnoidal (intrathecal) injection of local anaesthesic seems to be the most probable cause. The use of short needles should theoretically decrease the risk. Despite all these precautions, peribulbar anaesthesia should not be considered as an ordinary procedure. [Copyright &y& Elsevier]

Abstract

Noma causes tissue degeneration of the face resulting in impaired mouth opening with secondary malnutrition and metabolic disorders. Reconstructive plastic surgery for noma can be lifesaving but requires special airway and ventilation techniques because of limited mouth opening. In addition, the African context imposes logistic and budgetary constraints. The purpose of this article is to describe an upper airway management strategy that takes into account disease factors and available resources.

Abstract

Compressive pnemopericardium is an uncommon cause of shock after blunt trauma. The purpose of this report is to describe a case of air tamponnade observed during management of a patient with thoraco-abominal injuries in Dakar, Senegal. Diagnosis was suspected based on chest x-rays and subsequently confirmed by CT-scan. Clinical features included shock syndrome, small heart sign, and constant deterioration under assisted ventilation. Despite initial improvement after needle aspiration, the patient died due to probable recurrence of air tamponnade. Based on their review of the literature, the authors discuss the physiopathology of air tamponande and emergency treatment by needle aspiration that must be followed by surgery for creation of a pericardial window.
