Determination of visible near-IR absorption coefficients of mammalian fat using time- and spatially resolved diffuse reflectance and transmission spectroscopy.
In-vivo optical spectroscopy and the determination of tissue absorption and scattering properties have a central role in the development of novel optical diagnostic and therapeutic modalities in medicine. A number of techniques are available for the optical characterization of tissue in the visible near-IR region of the spectrum. An important consideration for many of these techniques is the reliability of the absorption spectrum of the various constituents of tissue. The availability of accurate absorption spectra in the range 600 to 1100 nm may allow for the determination of the concentration of key tissue constituents such as oxy- and deoxy-hemoglobin, water, and lipids. The objective of the current study is the determination of a reliable absorption spectrum of lipid(s) that can be used for component analysis of in-vivo spectra. We report the absorption spectrum of a clear purified oil obtained from pig lard. In the liquid phase above 36 degrees C, the oil is transparent and thus suitable for collimated transmission measurements. At room temperature, the oil is a solid grease that is highly scattering. The absorption and scattering properties in this solid phase are measured using time- and spatially resolved diffuse reflectance spectroscopy. Using these three independent measurement techniques, we have determined an accurate estimate for the absorption spectrum of mammalian fat.

[Follow-up of children born from gestosis mothers].
Seventy children, born from mothers affected from EPH gestosis during pregnancy, were examined. They were two-ten years old, forty females and thirty males, nineteen preterms and fifty-one born at term. Their weight, and head circumference were estimated. Thirty-two children were submitted to terman Merril test and further thirty-eight to Picq Vayer test. The findings were evaluated according to term or preterm birth and to importance of mother's gestosis (EPH1, EPH2, EPH3). The auxological outcomes were satisfactory, particularly after the five-six years of age. Two children were heavily retarded. The others had a normal I.Q., but there was evident failure in immediate memory and in vocabulary's subtest. Moreover fifty % of heavier gestosis children revealed a discordant psycomotor behaviour due to specific failures.

[Up-date on the subject of neonatal convulsions].
New experimental, clinical and therapeutic results in the field of convulsive disorders of the newborn have recently come to light. Experimental studies on animals have shown that, contrary to what was assumed in the past, the immature brain is highly excitable, and during the first weeks of life excitation processes predominate over inhibitory processes. Over the last ten years, benign idiopathic convulsions in newborns, familial convulsions and benign convulsions on the fifth day of life, have been defined. Both types develop and disappear spontaneously during the first week of life and have a favourable prognosis, although they may appear at the start (especially the benign fifth-day convulsions) as status epilepticus. Recently, two types of convulsive status epilepticus in newborns have been identified: a severe idiopathic status epilepticus and focal status epilepticus. The myoclonic syndromes which occur during quiet sleep and which are not accompanied by EEG discharges should be distinguished from convulsions and do not require anti-convulsive therapy. The various EEG monitoring techniques have shown an unexpectedly high number of convulsions, especially in the form of sub-clinical convulsions and/or atypical convulsive seizures. The atypical seizures distinctly predominate in status epilepticus. The clinical evidence of the seizures in reduced by administration of anti-convulsants, which seem to block typical seizures and, viceversa, to be less active for atypical seizures and EEG seizures. In the therapeutic field, the use of phenobarbital and/or phenytoin at a high initial dosage (20 mg/kg) has been well affirmed. Drugs such as lidocaine and thiopental are currently being experimented and have given encouraging results in severe status epilepticus.
