[Scientific Presentations at the meetings of the Spanish Pediatric Nephrology Association (AENP), 1988-2007]. / Comunicaciones científicas en los congresos de la Asociación Española de Nefrología Pediátrica (AENP), 1988-2007.

UNLABELLED: OBJECTIVES AND STUDY: To find out that characteristics of the scientific presentations given at the AENP's meetings in the past 20 years. METHODS: We reviewed in the scientific programs of the AENP's meetings of the past 20 years: number of presentations, number of participating institutions, institutions that provided the majority of the presentations, presentation format, number of studies involving experimental nephrology, topics most commonly presented. RESULTS: There have been 1,119 presentations in the past 20 years, 45/year between 88-92 and 67/year between 03-07. Ninety-one institutions participated in the meetings, 17/year between 88-92 and 34/year between 03-07. Pediatric Nephrology unit from the H. La Paz (Madrid) contributed the most presentations. Poster presentations were accepted at the ANEP meetings after 1995. Since then, 369 of the 815 presentations followed this format. Between 88-07 only 16 presentations dealt with experimental nephrology. The most common topics of presentation were glomerular disease (203) and urinary tract infection/VUR (132). Fifty-one presentations dealt with dialysis (almost 2/3 peritoneal). Transplantation was the topic of 123 presentations. Of the 21 presentations on molecular genetics only one happened before 1998. CONCLUSIONS: The poster is a useful alternative in scientific presentations which has allowed an increase in presentations, authors and institutions participating in the ANEP meetings. The main topic of presentation was glomerular disease. The frequency of presentations dealing with transplantation has increased in the last years. The past decade has seen more presentations on molecular genetics, but presentations dealing with experimental nephrology are still infrequent.

[Treatment of obesity in a hospital endocrinology clinic. Influence of parental body mass index]. / Tratamiento de la obesidad en la consulta de endocrinología de un hospital. Influencia del índice de masa corporal de los padres.

INTRODUCTION: Parental obesity is a risk factor for childhood obesity. The aim of this study was to determine if parental obesity influences the adherence and success of obesity treatment in a hospital paediatric endocrinology clinic. MATERIAL AND METHODS: An analytical, prospective, longitudinal study was conducted on obese children aged 4-14. An initial body mass index (BMI), and again at 6 months after receiving health, hygiene and dietary recommendations. Success was considered as a decrease of 0.5 in the BMI Z-score, and adherence to attending the 6-month review. Parental BMI was determined to identify overweight. The χ(2) test was used for qualitative variables and the T-Student test for quantitative (significance, p<<.05). RESULTS: The study included 100 children (52 male), 9.9±2.7 years old, BMI 28.1± 4.5kg/m(2) and BMI Z-Score 3.11±0.98. (85% had a BMI Z-score>3). More than half (59%) of the children had one or both parents obese (41 fathers and 37 mothers were obese). Treatment was not adhered to by 25 children. Adherence was worse if both parents were obese OR 3.65 (1.3 to 10.5) (P<=.01) and adherence was better if the mother was not obese, although the father was (P=.01). The treatment had significant success in 40 patients. If the mother was the only obese one in the family, the possibility of treatment failure was greater OR 5.6 (1.4 to 22.4) (P<.01) CONCLUSIONS: A high percentage of children with severe obesity have obese parents. The mother has an important influence on adherence and response to treatment for the severely obese child.

[Evaluation of isometric force in lower limbs and body composition in preterm infants]. / Valoración de fuerza isométrica en extremidades inferiores y composición corporal en prematuros.

INTRODUCTION: Strength is a physical quality with a clear influence on quality of life. It is determined by the structure of the musculoskeletal system, and depends on the muscular structure. It has been described that prematurity conditions both qualities. The aims of this study are to determine whether prematurity is associated with strength or body composition and evaluate the relationship between prematurity, strength and muscle mass. MATERIAL AND METHODS: Case-control study. Participants were premature 7-to-11 year-old children and full-term birth controls. Strength was measured by a strength gauge and body composition from DEXA (duel-energy X-ray absorptiometry) scans. A total of 89 subjects were included and divided into three groups: 30 prematures with birth-weight ≤ 1500g, 29 prematures with birth-weight 1500-2000g, and 30 controls. RESULTS: Weight and BMI z-score was lower in the premature group. No differences were found in muscular mass or strength between groups. A ratio was established between strength and weight or muscular mass. It was observed that it was possible for them to move four times their weight, without finding any differences between groups or a relationship with birth-weight. CONCLUSIONS: Between 7 and 11 years of age, children who were premature have lower weight and BMI than the rest of the children. However, there were no differences in body composition or strength between preterm children and controls.

[Amount of sleep and changes in its patterns in children less than two years old]. / Cuantificación del sueño y presencia de alteraciones en la duración del sueño en niños menores de 2 años.

OBJECTIVES: The aim is to study the sleep duration and the 24-hour sleep distribution pattern in children under 2 years-old from two different areas of Spain, as well as to determine the prevalence of abnormal sleep duration and the influence of age on this prevalence, and compare them with the already published data. MATERIAL AND METHODS: An observational, descriptive and cross-sectional study on children from two health centers: one in Castilla y León and the other in Asturias. Their parents completed the Brief Infant Sleep Questionnaire (BISQ). Daytime and nighttime sleep duration was assessed, with percentiles being used to evaluate the results. Two groups were created: one according to the age (children under or above 6 months), and the other according to the area. RESULTS: A total of 125 children were studied (73 males). The nighttime sleep duration increased from 8.28±2.06 hours to 10.43±1.21 hours (P=.0001) and the daytime sleep decreased from 4.61±2.66 to 1.96±0.79 hours (P=.0001) for children under 6 months and above 6 months, respectively. The children from Castilla y León slept more during daytime than those from Asturias (3.91±2.67 vs 3.00±2.09 hours, P=.041). Nineteen children had a total sleep duration below the 2nd percentile. A sleep duration below normal percentiles was observed in children under 6 months (14/72 vs 5/53, P=.006). CONCLUSIONS: As children grow older, they substitute daytime sleep for nighttime sleep. Approximately 15% of the children under 2 years-old may have changes in sleep duration, and is more common in children under 6 months.

[Evaluation of the capacity of elderly patients to make decisions about their health]. / Evaluación de la capacidad de toma de decisiones sobre su salud en pacientes ancianos.

OBJECTIVE: To assess the decision-making capacity and variables related to this, in elderly patients in a home care program. MATERIAL AND METHODS: A cross-sectional study was conducted on 130 patients assigned to home care program or in social welfare residences of an urban health centre. Demographic variables, as well as comorbidities, social support, institutionalisation, number of drugs used, degree of dependence (Barthel Index), cognitive function (Pfeiffer) were collected. The primary endpoint was the capacity for decision-making about their health assessed using the Aid to Capacity Evaluation (ACE) tool. RESULTS: There was a prevalence of 58.5% capacity. There was an association between ability and independence for activities of daily living (odds ratio (OR): 12.214; Confidence interval 95% (95% CI): 3.90 to 32.29, P <.0001) and function intellectual intact (OR: 282.750, 95% CI 34.0 to 2351.2, P <.0001). Numeric variables associated with the capacity for decision-making that had a more important effect size were the Barthel index (d: -1.398) and Pfeiffer index (d: 3.084). CONCLUSIONS: The prevalence of incapacity to make decisions about their health in elderly patients who are cared for in their homes is high. The level of dependence in activities of daily living and the deterioration of intellectual function are factors associated with the presence of this capacity.

[Metatropic dysplasia: a new case]. / Displasia metatrópica: un nuevo caso.

A new case of metatropic dysplasia in a 2.5 month old child is presented. Diagnoses was made in base of special face, long thorax, shortness of extremities with restricted joint mobility, kyphoscoliosis and a caudal appendage overlying the sacrum. Radiologically, expanded and irregular metaphyses of shortened tubular bones, platyspondyly and kyphoscoliosis. With growth, patients develop changes in body proportions. This syndrome is transmitted as an autosomal recessive. Prevention by genetic counseling is the principal measure.

[Management of chronic non-terminal renal failure in childhood. Estimation of mean annual cost]. / Manejo del niño en insuficiencia renal crónica no terminal. Una aproximación al coste medio anual.

We have calculated the mean annual cost (MAC) referred to 1,988 pesetas derived from the treatment and surveillance of 15 patients diagnosed of non terminal chronic renal failure (NT-CRF). The patients were aged between 1 month and 12 years at the moment of diagnosis and they were followed-up for five years at least. We have differentiated among costs from hospitalization, pharmacological treatment and outpatient control which were respectively 455,400, 47,798 and 57,917 pesetas/patient year. The costs from hospitalization decreased progressively every year after diagnosis being of 21,211 pesetas/patient year at the 5th year from diagnosis. The 30.1% of pharmacological treatment costs were due to the use of alkalines, 23.4% to phosphorus quelants (calcic carbonate mainly) and 27.3% to the active forms of vitamin D3. The outpatient surveillance costs corresponded 24,000 pesetas/year to staff expenses, 27,492 pesetas/year to laboratory work-up and 6,424 pesetas/year to radiological examination. We conclude that the total MAC for children with NT-CRF eas 561,115 pesetas/patient being the hospitalizations costs the most important concept (81.2%), followed by ambulatory care (10.3% and drug treatment (8.5%).

[Nephrotic syndrome in infancy: clinical, therapeutic and follow up characteristics in 100 cases]. / Síndrome nefrótico de la infancia: características clínicas, terapéuticas y evolutivas en 100 casos.

In order to understand the natural history, clinical features, anatomopathological findings and response to the initial treatment with steroids of the nephrotic syndrome (NS) during childhood, a group of 100 children under 14 years (46 with renal biopsy) observed for an average period of 4 years and 8 months, was reviewed retrospectively. The patients were divided into 3 groups: idopathic NC (89), secondary NS (9) and NS in the first six months of life (2). In the group of idiopathic NS, in which the significant predominance of males (2.8/1) was confirmed, in 69% of the patients the diagnosis was made between the ages of 2 and 5 years. Edemas were found, sometimes accompanied by oliguria and weigh gain, in 77% of the cases. The periods of hypertension and hematuria were infrequent and brief. Thirty eight kidney biopsies were carried out and showed: 25 minimal changes NS, 7 diffuse mesangial proliferative glomerulonephritis (DMPGN), 3 membranoproliferative glomerulonephritis (MPGN), 2 membranous glomerulonephritis (MGN) and 1 segmental and focal glomerulosclerosis. Of the 83 patients treated in first instance with corticosteroids, a positive response was obtained in 72 (87%), although 44% of them have shown to be cortico-dependent. After an average follow up period of 4 years and 8 months, only 2 children, one with MPGN and the other with MGN, are now in chronic renal failure (CRF). In 5 ot the 9 patients included in the second group, the NS was secondary to a Henoch Schönlein purpura. The kidney biopsies showed DMPGN in three of them.(ABSTRACT TRUNCATED AT 250 WORDS)

[Epidemiological study of nocturnal enuresis: analysis of associated factors]. / Estudio epidemiológico sobre enuresis nocturna en escolares: análisis de factores asociados.

OBJECTIVE: The purpose of this study was to analyze the different pathogenic factors in a large population of children. PATIENTS AND METHODS: A transverse epidemiological study was performed. Schoolchildren in the province of Leon between 6 and 10 years of age were studied during the 1991-1992 academic year. A randomly chosen sample of 2,165 children was used. The study was carried out by means of an anonymous survey given to the children's parents by the school. RESULTS: In addition to family antecedents of enuresis, the main associated factors were the mother's cultural status, with enuresis more frequent if the status was low, and the child's birth order. CONCLUSIONS: This study shows that certain family conditions favor the development of nocturnal enuresis.

[Primary and secondary nocturnal enuresis. Are they different entities?]. / Enuresis nocturna primaria y secundaria. Son entidades diferentes?

The aim of this study was to know the prevalence and predominant factors of primary and secondary enuresis in schoolchildren. For this purpose, a randomized epidemiological study was performed on a representative sample of the general population of children, aged 6 and 10 years, living in the province of Leon. Their parents responded to a questionnaire that evaluated, in both forms of enuresis, what are the predominant factors, including: familiar, socioeconomic, personal, education and psychological factors. We found that in a selected population of 1,307 children, 171 presented nocturnal enuresis when they were 6 years old (13.09% +/- 0.93%). Of these, 133 had primary (10.18 +/- 0.84%) and 38 (2.91 +/- 0.46%) secondary enuresis. We found no significant differences between the two forms in regards to familiar, socioeconomic, personal education or psychological factors. The only differences were that in secondary enuresis, the parents were older (p < 0.05) and less education (p < 0.01) on the subject of bladder control, and a later onset of the same (p < 0.05), was given. We conclude that the prevalence of primary enuresis is 10.18% +/- 0.84% and that of secondary enuresis is 2.91% +/- 0.46%. We do not find clear differences that permit us to consider these two types of enuresis as different forms.
