ABSTRACT: To describe the morbidity and mortality associated with congenital gastrointestinal obstruction, assess the usefulness of prenatal diagnosis, and analyze the results in relation to the site of obstruction.
We performed a retrospective case series study of 148 patients in a 13-year period (1990-2003). Sites of obstruction was classified into three groups: I) gastric, duodenal or jejunal; II) ileal or colonic; III) anorectal.
There were 65 patients in group I, 38 in group II and 45 in group III. Surgery was performed in 137 patients. Trisomy was diagnosed in 15 patients, polymalformation syndrome in 16 patients, and cystic fibrosis in seven patients. More than one site of intestinal obstruction was found in 22 patients (15 %). Morbidity consisted of nosocomial sepsis in 32 %, necrotizing enterocolitis in 7 %, and short gut in 3.4 %. Prematurity (48 %) was associated with higher morbidity and mortality. Overall mortality was 14.2 %, mainly associated with other malformations and extraintestinal problems. When patients with other extraintestinal malformations were excluded, the highest mortality was found in group II (OR: 12.19; CI: 2.4-76.2). The overall sensitivity of prenatal diagnosis was 0.44 and the mean gestational age at diagnosis was 31.6 weeks (SD 5.2). According to the site of obstruction, sensitivity was 0.77 in group I, 0.39 in group II and 0.04 in group III. Prenatal diagnosis did not alter prognosis.
Morbidity and mortality were strongly influenced by extraintestinal problems. The most severe intestinal complications were midgut volvulus and necrotizing enterocolitis. Prenatal diagnosis was late and showed good sensitivity only in group I.

ABSTRACT: To identify the determinants associated with uremia elevation in the first days of life in extremely premature infants.
We performed a prospective cohort study in a cohort of neonates born at less than 30 weeks of gestation.
Forty-eight preterm infants were included, of which 10 died. The mean fluid administration was 55, 72, 88 and 124 mL/kg on the first, second, third and seventh days of life. Amino acid doses were low in the first two days of life and were unrelated to uremia elevation. Thirty-one percent of the infants presented hypernatremia. Uremia was measured in 31 infants between the fifth and tenth days of life and 12 infants (38.7 %) had uremia values of 100 mg/dL or higher, without creatinine elevation. All of these infants were born at less than 27 weeks of gestation, weighed less than 850 grams at birth, and showed greater weight loss (19.2 % vs. 13.8 %; p 5 0.037) and higher natremia (150.2 mEq/L vs. 146.6 mEq/L; p 5 0.023). The use of furosemide increased the risk of elevated uremia (relative risk: 2.54; 95 % confidence interval: 1.05 6.14).
Total uremia of 100 mg/dL or higher was associated with dehydration, greater weight loss, higher natremia, furosemide use, lower gestational age, and lower birth weight.

ABSTRACT: To describe the corrected age (CA) of acquisition for sitting and walking in very low birth weight infants with cerebral palsy and to estimate the probability of walking as a function of age of acquisition of sitting and type of cerebral palsy.
Follow up study of very low birth weight infants (under 1500 g) admitted to the Neonatology Department of the Hospital 12 de Octubre in Spain between January 1991 and December 1996. At a corrected age of 2 years, 11.5% (34 children) were diagnosed with cerebral palsy. Ages of attainment of sitting and walking were established by interview with the parents and were confirmed by examination. Age of attainment of sitting and type of cerebral palsy were investigated as possible predictors of ambulatory status.
Sitting was attained by 73% of the children. The probability of attainment of sitting at 9 months was 21% and at 18 months it was 68%. Only one child achieved sitting after 18 months. Fifty-three percent of the children became ambulatory. The probability of becoming ambulatory was 24% at 18 months and 47% at 30 months. If sitting was attained before 12 months of age the probability of becoming ambulatory was 47% at 18 months and 76% at 30 months. All children with spastic hemiplegia, 66% of those with diplegia and only 8% of those with quadriplegia became ambulatory.
Sitting by the age of 12 months was directly related to achieving ambulation. Irrespective of the type of cerebral palsy, all children with hemiplegia and more than 60% of those with diplegia ambulated while children with quadriplegia were much less likely to ambulate.

ABSTRACT: To describe survival rates at discharge in liveborn infants with birth-weight under 1000 g by birth-weight and gestational age categories in a third level spanish hospital in order to improve health care planning and parental counselling about the threshold of viability.
A follow-up study of 178 infants with birth-weight under 1000 g born alive between 1991 at 1997. Six newborns with lethal malformations were not included.
Overall survival at discharge was 54%. During the study period survival rate improved in the birth-weight group 750-999 g. In the group below 750 g survival rate was lower and improved more slowly. Survival rate for infants below 750 g and 26 weeks was extremely low. Over 749 g and 25 weeks survival was over 50%.
Survival rate showed an improving trend during the study period. In the last years of the study period survival in infants with birth-weight over 749 g was above 85%. For infants under 750 g and 26 weeks was extremely low. Family and medical decision making about active treatment of these newborns should be an individualized process.

ABSTRACT: The objective of this study was to analyze the weight, length and head circumference development in prematurely born babies who weighed less than 1,500 grams and who were included in the follow-up program of our neonatal unit.
Review of data of the cohort included in the follow-up program between May 1990 and September 1995 was carried out. The weight and length were measured from 3 months of corrected age to 4 years of age. The head circumference was measured until 2 years of age.
We recruited 259 premature newborns (136 boys and 123 girls). The median gestational age was 30 weeks (23 to 36) and the median weight was 1,150 g (500 to 1,499 g). Twenty-seven percent were underweight for their gestational age (LWGA). The proportion of cases with weight below the 3rd percentile in the follow-up was stable around 25% in the group of adequate weight for gestational age. (AWGA). At 3 months of corrected age this proportion was 70% in the LWGA group, but there was a trend towards catch-up at 2 years of age. The worst results were obtained in the group that weighed less than 750 g at birth. The head circumference was better preserved than longitudinal growth and thus better than weight. All cases of head circumference below the 3rd percentile in the follow-up occurs in the LWGA group.
Weight was the parameter with the worst evolution during follow-up, especially in the group that weighed less than 750 g at birth. The group of LWGA tended to catch-up at 2 years of age.

ABSTRACT: The objective of this study was to establish the outcome at 3 years of age for very low birth weight newborns admitted to the Hospital 12 de Octubre from January 1991 to December 1993.
A follow-up study was performed. The pediatric assessment included a neurological, psychological, visual and audiological evaluation. At the end of the follow-up, children were blindly assessed to determine the rate of neurosensory disability. The severity of the neurosensory disability was graded as severe, moderate or mild by a functional classification. The rates of cerebral palsy, blindness and deafness were reported.
Two hundred fifty-three infants between 500 and 1,499 g were admitted to the Hospital 12 de Octubre of which 182 survived. Of these, 137 (75% of the survivors) were assessed at 3 years of age. The children who dropped out during the follow-up period had similar characteristics to those with a complete follow-up program except that the drop-out child was more likely to belong to a disadvantaged family. The rate of neurosensory disability was 28.5% (39/137), 16% were mild, 5% moderate and 7% severe. The rate of cerebral palsy was 13% (18/137), blindness 1.4% and deafness 0.7%.
Children from more disadvantaged families are less likely to continue in follow-up programs and this supposes a bias in the follow-up program. At 3 years, neurosensory disability was diagnosed in 1 out of every 4 children and cerebral palsy in 1 out of 8 children.

ABSTRACT: The objective of this study was to determine the incidence of surgical wound infection and the impact of this on the implementation of an antibiotic protocol according to the type of surgery and the prevailing endogenous flora in our neonatology unit.
Patients' charts were retrospectively reviewed in order to assess the effectiveness of a protocol of surgical prophylaxis, comparing the incidence of postsurgical wound infection in two periods of time. Surgical interventions were classified according to the period of the study in which they were performed, before (period A) and after (period B) the protocol was undertaken. In addition, if the antibiotics administered fit or not those indicated in the protocol, it was classified as correct or not.
A total of 31 (37%) of the interventions were performed in period A, whereas 53 (63%) were carried out in period B. No statistically significant differences were found between periods with regard to the proportion of infections 925.8% vs 15%). When prophylactic antibiotics were administered correctly, infection occurred in 10.2%, as compared to 31.4% when they did not fit the protocol (p < 0.05). The duration of the antibiotics was longer in period A, in infected wounds and when prophylaxis was not correct.
The correct adjustment to the protocol significantly decreases the incidence of wound infections, as well as the duration of antibiotic use. An appropriate policy of antibiotic prophylaxis in surgery is advantageous in terms of economic cost and might prevent antibiotic resistance and avoid unnecessary toxicity.

ABSTRACT: A study was performed to determine, in our population, the relationship between transcutaneous, visual and serum bilirubin values. This was done in attempts to reduce the number of serum bilirubin determinations to be performed in the future. We did a correlation coefficient between serum bilirubin and five measurements of transcutaneous bilirubin levels in a group of 60 term newborns and 60 preterm newborns, obtaining a value of 0.84 in both groups. The results were also considered from an analytical point of view where the ability of the test to predict an alteration in serum bilirubin levels, for example > or = 12 mg/dl in preterm and > or = 13 mg/dl in term newborns, was assessed. For values of 18 in preterm and 17 in term infants, the transcutaneous method was found to be both sensitive and specific. If Kramer's test is also evaluated the results improve.
