[Epidemiologic data on breast feeding in Florence and the province. Survey carried out in 1364 children born between 1985 and 1987].

We have studied the breast-feeding frequency in Florentine Area. We investigate a group of 1364 children born between January 1985 and June 1987. We collected following data: 1) Kind of feeding at birth. 2) Duration of breast-feeding related with birth-weight, kind of delivery, mother's age, mother's working activity. 3) Growth in relation to feeding practices from birth to 3rd month. The percentage of infants breast-feed in the hospital was 81.6%, 50.5% at the end of third month, 21.9% at the end of sixth month. We have found that children weighing more than 3000 g at birth had an higher frequency of breast-feeding at birth and last longer than children weighing less than 3000 g (p less than 0.01). Maternal age had a clear effect on both the incidence and the duration of breast-feeding. Mother aged 30 years or more begin to breast-feed in lower percentage but they continue breast-feeding for a longer time. One of the factors that has a negative influence on breast-feeding at birth is caesarean section since it precludes early mother-infant contact and early initiation of breast-feeding. Mother's resume working has a negative influence on breast-feeding duration. With regard to growth in first three months of life related with different kind of feeding we have found no differences between breast-feeding and artificial-fed infants.

[A new case of fronto-nasal dysplasia associated with craniosynostosis].

The Authors report a case of frontonasal dysplasia, a rare congenital syndrome, accompanied by multiple cranial synostosis. According to Cohen, frontonasal dysplasia associated with craniosynostosis may be considered as a separate syndrome and Cohen himself has described its occurrence in members of two families as "Craniofrontonasal Dysplasia". The Authors describe a sporadical case presenting various minor abnormality reported by Cohen, in addition to the hypoplasia of the corpus callosum, demonstrated by the Cranial Ultrasonography and by the NMR study of the brain.

[Sjogren-Larsson syndrome. Description of a case].

The authors describe a typical case of Sjogren-Larsson Syndrome showing a clear improvement of the spastic paresis after 2 years of physiotherapy and a diet rich in polyunsaturated fatty acids.

[A case of 9p partial monosomy caused by paternal translocation. Clinical and cytogenetic aspects].

The authors describe a case of partial monosomy 9p in a newborn infant, with breakpoint in the region p221, due to a father's balanced translocation with karyotype 46 XY t(9;16)(p221;q224). The phenotypical features of our patient reproduce those reported in other 35 cases described up to now in the literature: trigonocephaly, upward slanting palpebral fistures, little and horizontal mouth, disproportionally long fingers and toes. Some peculiar clinical and cytogenetical features of the case are discussed, particularly the early closure of the sternal body ossification centers (already detected during the prenatal life), the partial agenesia of the splenium corporis callosi and the partial anomalous pulmonary venous return. The Authors point out the importance of an early diagnosis, based on the awareness to the clinical abnormalities and dysmorphisms, in order to provide for an adequate and opportune genetic counseling.

[Pulmonary calcification in vitamin D poisoning in an infant].

We describe the case of a child aged 11 months with vitamin D intoxication and hypercalcemia, who developed acute renal failure and dyspnea. Chest X-rays showed interstitial changes compatible with either pulmonary alveolar proteinosis or pulmonary edema. The hypercalcemia suggested the possibility of metastatic calcifications of the lung. This hypothesis was subsequently confirmed by the progressive disappearance of pulmonary findings as calcemic levels returned to normal values... Our report emphasize the opportunity of studying the respiratory system in each patient with hypercalcemia, whichever the etiology may be.

[Treatment of nocturnal enuresis with a sound alarm. Study of 130 cases].

Nocturnal enuresis is a very common problem in childhood, various treatment have been suggested to cure bed-wetting, but the two most commonly used methods are the buzzer alarm and drugs. At Children's Hospital of Florence University, we dealt a trial to evaluate the effectiveness of conditioning treatment for nocturnal enuresis. We used a model alarm called "bell and pad". The child sleeps on a detector mechanism such as two separate metal mats that are connected with a buzzer alarm. When the voided urine wets the sheet, completing the electrical circuit, triggers the alarm and the child awakes. With repetition and unconscious inhibitory reflex is developed. 130 children were treated, 84 males and 46 females. Subjects were at least 6 years of age and not older than 15. 112 children had nocturnal primary enuresis and 18 secondary. The family history was positive in 70%. We had an initial interview with child and his parents. During this initial approach we explained the conditioning treatment. The child was given a diary card to record the bedwetting nights. We liked to see the child at three weekly intervals. After the child was dry for three consecutive weeks the metal mats was removed the bed. After a further three weeks of dryness the alarm was returned. Out of 130 cases there have been 109 cures (83%), whereas 21 (17%) haven't achieved dryness. There have been 14 relapses. Most children (77%) became dry within 12 weeks. The children with nocturnal secondary enuresis achieved later dryness. We believe that the use of enuresis alarm gives a high cure rate.(ABSTRACT TRUNCATED AT 250 WORDS)

[Rare case of double cyst of the omentum].

In Pediatric Surgery "A. Meyer's" Hospital of Florence in the period 1973-1982 a people of 140.000 children is recovered. The AA report a case of double omental cyst, that is arrived in Hospital only for an increase of the abdomen. The omental cyst are uncommon in pediatric age and presents etiopathogenetic aspects still controverted.

[Bilateral extrinsic ophthalmoplegia in infectious mononucleosis].

The AA. describe an eight years old child with extrinsic bilateral ophthalmoplegia associated with infectious mononucleosis. On the right (eye) a compromise of the VI (partial) and the III (total) pairs of cranial nerves was evident. On the left all extrinsic oculomotor nerves were interested.

Cardiac troponin I in patients with hematologic malignancies.

BACKGROUND: The cardiac isoform of troponin I (cTnI) is a myofibrillar protein highly specific for myocardial injury. We used a recently developed new-generation immunoassay with high analytical sensitivity to measure cTnI in patients diagnosed with hematologic malignancies, before chemotherapy and after an intermediate cumulative dose of anthracyclines. We hypothesized that measurement of cTnI with this sensitive method would provide evidence of myocardial injury in these patients. METHODS: Sera from 115 individuals (60 healthy controls, 25 anthracycline-naive patients and 30 patients treated with intermediate cumulative doses of anthracyclines) were assessed for cTnI, creatine kinase MB (CKMB) mass and myoglobin. Radionuclide left ventricular ejection fraction (LVEF) was also determined. RESULTS: Using this sensitive assay, detectable concentrations of cTnl were measured in the healthy population [mean, 19.5 pg/ml, 95% confidence interval (CI) 13.5-25.5 pg/ml]. Anthracycline-naive patients had cTnI mean values (36.5 pg/ml, 95% CI 25.1-47.9 pg/ml) that were significantly (P < 0.01) greater than those in the control group. cTnI was significantly (P < 0.00001) increased in anthracycline-treated patients (76.4 pg/ml, 95% CI 67.0-85.8 pg/ml) compared with both the anthracycline-naive patients and the controls. CKMB, myoglobin and LVEF were within the normal range in all patients. CONCLUSIONS: These data provide evidence for cardiac involvement in patients with hematological malignancies before and during the course of anthracycline chemotherapy. They suggest that detection of myocardial injury may be facilitated by measurement of cTnI with a highly sensitive assay.
