Revisiting the Fabry-Perot reflectivity method for mid-infrared optical index measurement: case study of InGaAs, AlInAs, and InP.

We revisit the Fabry-Perot (FP) reflectivity method to measure optical indices in the mid-infrared spectrum. This simple approach can be readily implemented using a standard Fourier transform infrared spectrometer. Measuring samples with multiple heights allows for enhanced precision of the measurement, making the FP method consistent in values and uncertainties with more advanced ellipsometric measurements.

[Neonatal seizures revealing incontinentia pigmenti].

Incontinentia pigmenti (IP) is a rare affection inherited as X-linked dominant disease. It is usually lethal in male infants. IP can affect ectodermal tissues such as the skin, teeth, eyes, bones, and the central nervous system.

[Systemic congenital candidiasis, a rare condition in neonates: case report in a premature infant].

Unlabelled: Congenital cutaneous candidiasis presenting at birth is very uncommon and is due to intra-uterine infection. The systemic form has to be considered when cutaneous signs are associated with sepsis symptoms.

Case Report: A female infant was born by vaginal delivery at 35 weeks' gestation to a mother whose pregnancy had been complicated by urinary tract infection treated 3 days before delivery.
