[Rickettsiosis after tick bite: A subtle clinic picture on many occasions, we must be vigilant]. / Rickettsiosis tras la picadura de una garrapata: una clínica sutil en muchas ocasiones, debemos estar atentos.

Rickettsia diseases are a group of tick-borne transmitted diseases, classified into 2 large groups: spotted fevers and typhus fevers. In addition, a new condition has been described recently, known as tick-borne lymphadenopathy. A retrospective series is presented of paediatric cases of rickettsia diseases diagnosed in 2013 and 2014. A total of 8 patients were included, of which 2 of them were diagnosed as Mediterranean spotted fever, and 6 as tick-borne lymphadenopathy. Rickettsia slovaca, Rickettsia sibirica mongolitimonae, and Rickettsia massiliae were identified in 3 of them. Aetiology, clinical features and treatment carried out in each of them are described. The interest of these cases is that, although most have a benign course, the high diagnostic suspicion and early treatment seem to be beneficial for its outcome.

Effect of Protein Intake Early in Life on Kidney Volume and Blood Pressure at 11 Years of Age.

High protein intake has been associated with kidney hypertrophy, which is usually reversible; however, when it occurs early in life, it could lead to cell programming with a long-lasting effect. This study aimed to assess whether higher protein ingestion early in life has a persistent effect on kidney volume at 11 years of age, as well as its influence on blood pressure. This is a secondary analysis of a randomized control trial that compared the growth of infants fed with a higher-protein formula versus those fed with a lower-protein formula, with a control group of breastfed infants. Renal ultrasound and anthropometric measurements were assessed at 6 months and 11 years of age. At 11 years, urinary protein, albumin and creatinine, and blood pressure were measured in 232 children. Feeding with a higher-protein formula was associated with a larger kidney volume (ß = 8.71, 95%CI 0.09-17.33, p = 0.048) and higher systolic blood pressure (ß = 3.43, 95%CI 0.78-6.08, p = 0.011) at 11 years of age. Microalbuminuria was detected in 7% of the patients, with no differences among groups (p = 0.56). The effect of increased protein ingestion early in life may condition kidney volume and blood pressure in later childhood.

[Treatment for children and adolescents with pain in Spain: data from a survey on current specialized programs]. / El tratamiento del dolor en población infantojuvenil en España: Datos de una encuesta sobre los programas especializados existentes.

OBJECTIVE: The treatment of children and adolescents with pain has improved considerably in the last 30 years. In Spain, progress is also evident, and specialized units or programs have emerged as part of the care provided for this population. However, there are no studies on the characteristics or activities of these specialized units or programs. This lack of information prevents an adequate evaluation of the current procedures, and hinders an adequate administration and management of these resources. The objective of this work was to study the characteristics of these units and programs for the treatment of children and adolescents with pain in Spain. METHODS: A total of 10 specialized units or specific treatment programs for pediatric pain in Spain were identified, and the person responsible was contacted. Through a self-administered online survey, information was collected on the organization of the program, the involvement in relevant fields such as research, training of professionals and the raising of awareness and visibility of the problem, the specialties involved, the type of treatments offered, the evaluation of results and the services provided. RESULTS: Of the ten units or programs contacted, eight answered the survey (80%). Pain programs for children and adolescents proved to be primarily pharmacological, also for chronic pain. They reported to promote awareness about the problem (88%), to contribute to the training of specialists (88%) and to a lesser extent to research and knowledge generation (75%). CONCLUSIONS: This survey provides valuable information on the current characteristics of specialized programs and units for the treatment of children and adolescents with pain in Spain, and can be used to propose actions that improve its current management and administration.

OBJETIVO: El tratamiento de la población infantojuvenil con dolor ha mejorado considerablemente en los últimos 30 años. En España, el progreso también es evidente, y han surgido unidades o programas especializados como parte de la atención a esta población, aunque no existen estudios sobre las características o la actividad de estas unidades o programas especializados. Esta falta de información impide una evaluación adecuada de los procedimientos vigentes y dificulta una adecuada administración y gestión de estos recursos. El objetivo de este trabajo fue conocer las características de estas unidades y programas para el tratamiento de la población infantojuvenil con dolor en España. METODOS: Se identificaron un total de 10 unidades especializadas o programas de tratamiento específicos del dolor infantil en España y se contactó con la persona responsable. A través de una encuesta autoadministrada online se recogió información sobre la organización del programa, su implicación en ámbitos relevantes como la investigación, la formación de los profesionales, la sensibilización y visibilidad del problema en la sociedad y entre los profesionales, las especialidades implicadas, el tipo de tratamientos que se ofrecen, la evaluación de resultados y los servicios prestados. Se han utilizado medias y porcentajes para describir los resultados. RESULTADOS: De las diez unidades o programas contactados, ocho contestaron a la encuesta (80%). Los programas de tratamiento del dolor infantojuvenil demostraron ser fundamentalmente farmacológicos, también en los casos de dolor crónico. Informaban de que se preocupaban por impulsar la sensibilización de los especialistas y la sociedad sobre el problema (88%), de contribuir también a la formación de especialistas (88%) y, en menor medida, de investigar y generar conocimiento (75%). CONCLUSIONES: Esta encuesta proporciona información valiosa sobre las características actuales de los programas y unidades especializadas para el tratamiento de la población infantojuvenil con dolor en España. Puede servir para proponer acciones que mejoren la gestión y administración actual.

[Unilateral renal agenesis. New arguments about the genetic relationship between kidney malformations and urolithiasis]. / Agenesia renal unilateral. Nuevos argumentos acerca de la relación genética entre la urolitiasis y las malformaciones renales.

BACKGROUND: In few previous works, it has been reported that hypercalciuria is associated with some types of CAKUT, namely ureteropelvic junction obstruction, vesicoureteral reflux or simple renal cysts. In addition, one higher prevalence of hypercalciuria and/or urolithiasis has been described in their family members compared to the general population. This study was carried out to find out whether children with unilateral renal agenesis (URA) have these features previously described in other CAKUT types. METHODS: In a descriptive and multicenter study we studied the prevalence of hypercalciuria, hypocitraturia and urolithiasis in 67 children (43 males and 24 females) with URA and their families. RESULTS: The two metabolic anomalies that promote stone formation were observed in 26 children (38.8%), distributed as follows: hypercalciuria in 16, hypocitraturia in 9, and both hypercalciuria and hypocitraturia in 1. Eight children (11.9%) suffered renal colic during follow-up. Familial history of urolithiasis was found in 42/67 children (62.7%): in 12 of the first-degree relatives, in 15 of the second degree relatives and in 15 patients both in the first-degree as in their second degree relatives. In contrast, in historic control group, only in 28.1% of families at least one member had urolithiasis. CONCLUSION: Our results show that the prevalence of hypercalciuria and/or hypocitraturia is greater in pediatric patients with URA than in the general population. Likewise, the prevalence of urolithiasis in the families of these children is also higher than that in the general population.

A longitudinal study on the effects of maternal smoking and secondhand smoke exposure during pregnancy on neonatal neurobehavior.

Maternal smoking during pregnancy is one of the most modifiable causes of morbidity and mortality for both pregnant women and their fetuses. The long-term effects of prenatal exposure to smoke on child behavior and development have been the subject of more extensive research than have the short-term effects. Therefore, the aim of this work is to examine the effects of smoke exposure during pregnancy on neonatal behavior, including in our study a group of mothers exposed to secondhand smoke. The behavior of 282 healthy full-term newborns was assessed using the Neonatal Behavior Assessment Scale (NBAS) at 48-72 h of life. Sixty-two mothers smoked during pregnancy (no mother smoked more than 15 cig/day) and 17 were exposed to secondhand smoke. After adjusting for socio-demographic and obstetric factors, both newborns whose mothers smoked and those whose mothers were exposed to secondhand smoke showed significantly lower scores in the habituation cluster than non-smoking mothers. Exposure to secondhand smoke was also related to lower motor system cluster scores as well as some supplementary items and the newborns of smoking mothers showed significantly lower scores in the state regulation cluster and in some items of the state organization cluster than the newborns of non-smoking mothers. We conclude that active and passive smoking during pregnancy affects several aspects of neurobehavioral development, regardless of socio-demographic, obstetric and pediatric factors.

[Conservative versus interventional treatment of primary vesicoureteral reflux in children]. / Tratamiento médico-conservador versus intervencionista del reflujo vesicoureteral primario en el niño.

OBJECTIVES: To assess the efficacy of medical and surgical treatment of vesicoureteral reflux (VUR) in children using recurrence of urinary tract infections, renal scarring and renal function as end-points. METHODS/RESULTS: We performed a MEDLINE search for articles. We selected only randomized clinical trials and meta-analysis that analyzed medical versus surgical treatment of VUR in children. A total of 820 patients were included in all studies. We found no statistatically significant differences between surgically and medically treated patients in terms of scarring, kidney function or recurrence of urinary tract infections. There was only a significant decrease in the frequency of febrile UTI in patients who were surgically corrected, compared with those receiving antibiotics alone (RR 0.43). CONCLUSIONS: We found no clinically significant differences between surgical and medical treatment for VUR in terms of kidney function or renal scarring. We suggest that a child with UTI and VUR should be treated conservatively at first.

[Current status of antibiotic prophylaxis in primary vesicoureteral reflux in children]. / Situación actual de la profilaxis antibiótica en el reflujo vesicoureteral primario en el niño.

OBJECTIVES: To assess the efficacy of antibiotic prophylaxis for prevention of urinary infections and renal parenchymal damage in children with primary vesicoureteral reflux (VUR). METHODS/RESULTS: A search based on MEDLINE and The Cochrane Library was performed selecting those clinical trials and meta-analysis which compared antibiotic prophylaxis (either continuous or intermittent) and placebo or no treatment at all in children with primary VUR. Three systematic reviews were chosen for assessing the efficacy of prophylaxis of urinary infections including trials with a predominant paediatric population without known VUR. Results showed that the use of antibiotics decreased the risk of urinary infection. The quality of the trials was, however, insufficient and therefore of questionable results. We also selected two randomized controlled trials in children with reflux: one had limited information as the degree of reflux was not stated; the second assessed the results in a population of 113 children with VUR grade I to III (55 receiving prophylaxis and 58 not) following acute pyelonephritis. There were no differences with regard to the risk of urinary infection or the risk of renal parenchymal damage. CONCLUSIONS: There is not enough evidence supporting generalized use of antibiotics to prevent urinary infections. No benefit in prophylaxis has been proven for VUR grades I to III. There is no data for high grade VUR. It will be necessary to perform more trials in order to establish more accurate recommendations on prevention of urinary infections in the presence of VUR.
