[Urinary tract ultrasonography in newborns with late oligohydramnios]. / Indagine ecografica dell'apparato urinario in neonati con oligoidramnios tardivo.

BACKGROUND AND AIM: The aim of this study was to evaluate the value of neonatal renal ultrasonography in the diagnosis of urinary tract malformation pathologies in newborns from pregnancies complicated by late oligohydramnios. METHODS: During the period January 1994-October 1997, 119 newborns from pregnancies complicated by oligohydramnios occurring in the third trimester of pregnancy underwent ultrasonography of the urinary tract at our Centre. All newborns had previously undergone prenatal ultrasonography. RESULTS: Ultrasonography revealed calicopyelic dilatation < 10 mm in 7 newborns (5.8%), 5 of whom had already been reported at the prenatal ultrasonography. One new-born (0.8%) also showed the presence of an ectopic kidney that had not been diagnosed at the prenatal scan. By the next follow-up all the calico-pyelic dilatations had become normal. CONCLUSIONS: Neonatal ultrasonography did not show any alterations to the urinary tract that might be responsible for the reduction of amniotic liquid. We therefore feel that is useful to perform neonatal ultrasonography in those situations in which the onset of oligohydramnios occurred in the second trimester of pregnancy and in cases in which no scan was performed during the prenatal period.

Renal blood flow velocity in preterm and term neonates during the fourth day of life: changes in relation to gestational age and birth weight.

Measurements of renal artery blood flow velocity have been previously reported during prenatal life and during the first month of life in neonates. Since renal flow velocity increases during the first 3 days of postnatal age we determined, during the fourth day of life, the changes of renal blood flow velocity in relation to gestational age and birth weight in 109 healthy preterm and term infants with gestational age between 26 and 42 weeks and birth weight between 750 and 3,730 g. Renal arteries were insonated about 3 mm from the abdominal aorta, by placement of a microconvex 7-MHz transducer below the costal margin in the dorsolateral area of the right or left flank. Mean flow velocity significantly increased with advancing of gestational age and birth weight. This study provides normative data for renal artery blood flow velocity in healthy preterm and term infants during the fourth day of life.

[Middle lobe syndrome in children. Critical review]. / La sindrome del lobo medio nel bambino. Rivisitazione critica.

The clinical, radiological and anatomo-evolutive pictures of this syndrome are typical. It is suggested that cases are more frequent than is generally thought and that their recognition is delayed on account of the considerable time that often elapses before repeated infection of the respiratory system, particularly the middle lobe, results in the onset of the syndrome.

[Guideline for the prevention of sexually transmitted diseases in adolescents (University of Florence, Pediatric Department)]. / Linee guida per la prevenzione delle malattie sessualmente trasmesse (MST) nell'adolescente.

Adolescent had in the past rarely been affected by sexually transmitted infections. Nowadays they must be considered possibly running such risks as they begin their sexual activity earlier or do not know enough about these kinds of troubles. Therefore a valid primary prevention is necessary based upon correct information.

[Leukorrhea in adolescents: an underestimated problem]. / Le leucorree nell'adolescente: un problema sottostimato.

It is by now clear that pediatrician's interest about adolescent's matters is very much increasing. The Authors take into consideration vulvovaginitis, a particular matter which is very frequent during this period of life and describe its most important clinical aspects.

[Infantile idiopathic scoliosis with onset in the 1st year of life]. / La scoliosi idiopatica infantile ad insorgenza entro il primo anno di vita.

The clinical and radiological characteristics of idiopathic scoliosis with onset in the first year of life is described. The importance of a careful objective examination of nurslings with respect to scoliosis is stressed.
