[Decrease of frequency of male lung cancer in Umbria region. 1978-1982 and 1994-1999].

In Umbria, region of Central Italy, lung cancer is the leading cause of death due to cancer in males. The aim of this work is to highlight decrease of mortality from lung cancer in males in Umbria, in the last 20 years and to describe relationship among incidence, mortality and survival of this cancer. The incidence data derived from an ad hoc survey carried out over the period 1978-1982 and for 1994-1999 from the Umbrian Population Cancer Registry (RTUP). The mortality data were derived from official publications of the Italian Central Institute for Statistics (ISTAT) and covered the entire period 1978-1999. Estimated annual percent change (EAPC) was calculated by joinpoint regression analysis. Decrease of mortality from male lung cancer in Umbria began in the 1990-ies due to reduced quantity of tar in cigarettes, decreasing consumption of tobacco and increasing of survival derived from the quality and the effectiveness of the oncological health care system.

[The nasogastric feeding of preterm newborns].

The aim of this study is to investigate if nasogastric feeding may provide an adequate caloric intake and a good growth in preterm infants. One hundred and thirty-one newborns with gestational age less than or equal to 33 weeks, admitted to the Neonatal Unit of the Catholic University of Rome over a period of three years, were included in the study. Infants were divided according to birth weight in four groups: the first includes 22 neonates weighing less than or equal to 1000 g; the second 60 newborns with birth weight of 1001-1500 g; the third includes 36 prematures weighing 1501-2000 g; the fourth group 19 neonates with birth weight greater than 2000 grams. Body weight was measured daily and head circumference weekly for all the study period (60-90 days). Mean postnatal weight loss was greater in the lowest birth weight group (13.2% of the birth weight) as compared to the other three groups (8%-9%). Birth weight was regained at 18th day of age in the newborns of the first group and in the second week of age in the other three groups. A caloric intake greater than 100 Kcal/Kg/day was achieved in the second week, ranging between the 8th day (forth group) and 14th day (first group). The achievement of full enteral feeding was inversely related to the birth weight.(ABSTRACT TRUNCATED AT 250 WORDS)

[Imaging of enthesopathies of the ligamentum patellae in athletes. Echography and computerized telethermography].

The authors examine the diagnostic value of two non-invasive techniques--i.e. ultrasound and computerized teletermography--in the diagnosis of patellar enthesopathies. Such a pathology is quite frequent in young athletes, at various stages. The patients were grouped in two categories, according to their age when the trauma occurred, and to the peculiarities of both enthesopathic localization and imaging. The use of both techniques, either one prevailing over the other according to the different evolutive phases of enthesopathies, provides useful information as to detecting and determining the disease. Finally, the authors recommend a combined use of these techniques, especially in young athletes, possibly avoiding conventional X-rays.

[Photoprevention or phototherapy in newborn infants born prematurely?].

The authors studied the effects of different kinds of phototherapy in 186 newborns with a gestational age less than 33 weeks and weighing less than 2500 g. A control group of 60 infants was compared with a group of 31 infants submitted to photoprophylaxis, a group of 54 infants treated with day light, and a group of 41 infants treated with day light + special blue light. As far as the serum bilirubin variations in the first week, the maximum levels attained and the number of exchange transfusions are concerned, phototherapy always proved effective in reducing potentially neurotoxic serum bilirubin concentrations. Among the infants subjected to treatment, those treated with the day light showed a significant smaller decrease of serum bilirubin compared to those treated with the day light + special blue light, even if levels above 15 mg/dl were found in a similar percentage. Only 3.2% of the babies treated with photoprophylaxis showed serum bilirubin values above 15 mg/dl. The authors conclude that prophylaxis seems to be preferable to other phototherapeutic schedules used in the treatment of hyperbilirubinemia in low gestational age infants.

[Assistance procedures in the perinatal period that condition breast feeding at the time of discharge from the hospital].

The authors have evaluated the influence of some obstetric events (type and duration of labour and method of delivery) and some pharmacological factors (oxytocic drugs during labour, local infiltration, duration of general anaesthesia, oxytocic drugs and/or ergot derivatives during puerperium) on frequency of breast-feeding at the time of discharge from hospital. About 57% of 356 newborns were breast-fed (wholly or prevalently) at discharge from the "A. Gemelli" University Hospital in Rome, during two months period (march-april 1981). The results showed that all those conditions requiring medical and paramedical action, either instrumental or pharmacological (such as: induced labour, prolonged labour, operative delivery either vaginal or abdominal, particularly in emergency; use of local infiltration; use of oxytocic drugs during labour, particularly for induction; prolonged general anaesthesia in caesarean section) may have an unfavorable effect, nearly always significant, on breast-feeding. According with these results, the Authors suggest the following measures for breast-feeding promotional programme: modification of neonatal routine care to promote an earlier mother-infant interaction during lying-in; limitation of avoidable obstetric procedures and of drugs giving to mothers; a better understanding of pharmacokinetics, both in mothers (placentar passage of drugs and through milk) and in newborns during labour, delivery and puerperium.

[Physiologic hyperbilirubinemia in low birth weight newborn infants: relation to gestational age, neonatal weight and intra-uterine growth].

Neonatal hyperibilirubinaemia is a real problem for its possible repercussion on the psychomotor development, mainly in low birth weight infants. The Authors studied the physiologic course of bilirubinaemia in 513 low birth weight newborns and then related it to gestational age, birth weight and intrauterine growth. Results obtained show that neonatal hyperbilirubinaemia is strictly depending on gestational age, while both the birth weight and the intrauterine growth have no significant influence on its course. Certainly the very low birth weight infants run the higher risk of Kernicterus and brain injury due to hyperbilirubinaemia; they need therefore a quicker therapeutic approach, though the treatment of physiologic hyperbilirubinaemia must always be planned on the basis of gestational age.

[Efficacy of phototherapy in the low weight newborn infant: relation to gestational age, birth weight and intra-uterine growth].

Phototherapy is largely used in the management of neonatal hyperbilirubinaemia, but its safety is very far from being proved. The Authors studied the effectiveness of daylight in low-birth-weight newborns. The results obtained show that the reduction of bilirubin induced by phototherapy is related with gestational age and intra-uterine growth. The very low-birth-weight infants, at higher risk of kernicterus, as they are more responsives to phototherapy, as well they are, probably, more susceptibles to side-effects. The Authors think that phototherapy should be planned on the basis of such observations.

[Which light for phototherapy of the low birth weight infant?].

We have compared three different fluorescent light sources (true light, blue light, true light + blue light) for phototherapy in 155 low birth weight newborn babies affected with non haemolytic hyperbilirubinaemia. Our data suggest that blue light is significantly more effective than true light. Surprisingly the association of true light with blue light is significantly more effective than both true light and blue light separately. The greater effectiveness associated with the better tolerance of true light + blue light respect to blue light only, makes it preferable than phototherapy regimen, even if more extensive study on its effectiveness and on short and long term side effects are need.

[Ineffectiveness of vitamin 25(OH)D3 in the prevention of hypocalcemia induced by phototherapy].

Phototherapy causes a higher incidence of hypocalcemia in preterm infants by still unknown pathogenetic mechanism. The authors studied 100 preterm newborns in order to verify whether Calcifediolo (25-OH-D3) could be useful to prevent the phototherapy-induced hypocalcemia. Results obtained show that Calcifediolo is not able, anyway, to lower the increase of the phototherapy-induced hypocalcemia in preterm infants. Vit D is therefore unlikely to play any important role in the patogenesis of phototherapy-induced hypocalcemia.

[Hypothyroxinemia in the low birth-weight infant in the screening of congenital hypothyroidism].

Inside a pilot screening program for Congenital Hypothyroidism, T4 and TSH have been tested in sick and healty preteam and fullterm low birth weight (LBW) newborns during the first two months of life, 36 newborns affected by respiratory distress syndrome and 15 by sepsis have been included in the study. Blood samples were collected by heel puncture on 3rd, 10th, 20th, 40th and, in some cases, up to 60th day of life, and adsorbed on filter paper. Our findings show that hypothyroxinaemia in LBW newborns is strictly related to gestational age. In fact, among preterm infants with GA less than or equal to 33 weeks, 25 subjects (69,44%) showed T4 levels less than or equal to 6 micrograms/dl and 5 infants (13,88%) had T4 concentrations less than or equal to 2 micrograms/dl. The incidence of subjects with T4 values less than or equal to 6 micrograms/dl falls to 42,18% in the group of infants with GA = 34-36 weeks and to 17,27% in the group of fullterm LBW infants. None of these newborns showed thyroxine levels less than or equal to 2 micrograms/dl. All the examined infants showed normal TSH levels. The low T4 values may appear soon after birth or later (3rd-20th day of life) and sometimes persist up to 40th or 60th day, despite of always normal TSH levels. The mean of low T4 values at each sampling time is strictly and directly related to gestational age. (ABSTRACT TRUNCATED AT 250 WORDS)

[Possible pathogenetic factors in hypocalcemia of low birth weight newborn infants (author's transl)].

The Authors studied the possible pathogenetic factors in hypocalcemia of 66 low birth weight healthy newborn infants, 28 preterm and 38 small for gestational age babies. To clarify the pathogenesis of neonatal hypocalcemia, the Authors determined daily in the first week of life serum calcium, phosphorus and magnesium concentrations, the serum natrium and kalium level and E.A.B. on capillary blood. Total serum proteins was determined on the 2nd and on the 7th day of age. The incidence of hypocalcemia was 25.7% for all considered babies: 32.1% for preterm infants and 21% for small for gestational age babies. The hypocalcemia of preterm babies appears early during the first three days of life and it results not correlated with the serum phosphorus and the serum magnesium concentrations. On the contrary the small for gestational age babies show a "late" hypocalcemia directly related with an elevated serum concentration of phosphorus and with a reduced serum magnesium level. Both the preterm and the small for gestational age newborn infants had asymptomatic hypocalcemia and the orally administration of high doses of calcium gluconate 10% was able to normalize rapidly the serum calcium level.

[The disease of beta 2-amyloid deposition in the differential diagnosis of juxta-articular subchondral geode lesions].

Beta-2 amyloidosis deposition is a new type of amyloidosis recently observed in long-term hemodialysis patients. One of the major osteoarticular complications of this disease is the appearance of subchondral bone cysts. In this paper the radiologic features of such radiolucencies are described and the criteria are outlined of the differential diagnosis from the geodes found in other arthropathies or para-physiologic conditions. The importance of the status of the joint space is stressed: on the basis of its patterns, arthropathies may be grouped as follows: inhomogeneous space narrowing in degenerative arthritis; homogeneous space narrowing in inflammatory arthritis; normal or nearly normal joint space if there is no/not-prevalent involvement of articular cartilage.
