Abstract: The present invention relates to pharmaceutical compositions for the parenteral administration of melatonin in the form of sterile aqueous solutions, provided with good stability even if devoid of any stabilising excipients and having a concentration of melatonin up to high amounts, sufficient for an efficacious medical treatment.

Abstract: The present invention concerns an automatic method for measuring a baby's cry, comprising the following step: A. having N samples ?(i), for i=O, 1, . . . , (N?1), of an acoustic signal p(t) representing the cry, sampled at a sampling frequency? for a period of duration P; the method being characterised in that it assigns a score PainScore to the acoustic signal p(t) by means of a function AF of one or more acoustic parameters selected from the group comprising: —a root-mean-square or rms value prms of the acoustic signal p(t) in the period P; —a fundamental or pitch frequency F0 of the acoustic signal p(t), i.e. the minimum frequency at which a peak in the spectrum of the acoustic signal p(t) occurs in the period P; and—a configuration of amplitude and frequency modulation of the acoustic signal p(t) in the period P. The invention further concerns the apparatus performing the method.
