Comparison of two methods for cleaning breast pump milk collection kits in human milk banks.

BACKGROUND: Appropriate decontamination of breast pump milk collection kits (BPKs) is critical to obtain safe milk for infants and to avoid discarding donor human milk (DHM). AIM: To evaluate two strategies for BPK decontamination by assessing microbial cultures and the proportion of discarded DHM, according to the criteria of the National Institute for Health and Care Excellence for pre-pasteurization cultures. METHODS: Prospective comparative study, allocation ratio 1:1, microbiologist-blind. PARTICIPANTS: 47 new donors in a human milk bank in Madrid. INTERVENTIONS: Study group (N=21): BPKs washed with water and detergent after each use and further steam decontamination within a microwavable bag. Control group (N=26): washing, rinsing and drying only. Five samples: first sample by hand expression and four samples (one per week) collected using the same pump and method. OUTCOMES: Primary: proportion of DHM discarded due to contamination. Secondary: comparison of the microbiota between samples obtained by hand expression and breast pump in both groups. FINDINGS: In total, 217 milk samples were collected: 47 by hand expression and 170 by pump expression (78 from study group). Steam decontamination of BPKs using a microwavable bag after washing resulted in a lower proportion of discarded DHM samples (1.3% vs 18.5%, P<0.001) and samples contaminated with Enterobacteriaceae (1.3% vs 22.8%, P<0.001) and Candida spp. (1.3% vs 14.1%, P<0.05) compared with samples collected with BPKs that were washed but not steam decontaminated. There were no differences in bacterial contamination between samples obtained using steam decontaminated BPKs and those obtained by hand expression. CONCLUSIONS: Steam decontamination of BPKs using a microwavable bag after washing decreases the amount of discarded DHM and the number of samples with potentially pathogenic bacteria.

Association between maltreatment and polydrug use among adolescents.

Different studies have related sexual and physical abuse during childhood and adolescence to the development of substance abuse disorders. Nevertheless, we are not aware of the role that other more common maltreatment types, such as neglect, will play among the most risky pattern of consumption: the polydrug use. A clinical sample of 655 adolescents, divided into two groups: polydrug users and non-polydrug users, were assessed on their pattern of drug consumption, history of childhood maltreatment, current psychopathology and their family history of alcoholism. Polydrug users had a greater prevalence of all types of maltreatment, although the most associated to this group were sexual abuse and emotional neglect. Other relevant variables to adolescent consumption were: the diagnosis of depressive disorder, the presence of anxiety traits and the family history of alcohol dependence. Polydrug users have higher risks of having had problems during infancy and adolescence, such as maltreatment and other psychopathological conditions, with the addition of family history of alcoholism. Accordingly, practitioners should take into account that those variables may influence polydrug abuse because it is the most risky pattern for subsequent dependence of substances, and they should always be considered during treatment.

Comparative study of RetCamRetCam II vs. binocular ophthalmoscopy in a screening program for retinopathy of prematurity.

OBJECTIVE: To determine the performance of RetCam vs. binocular ophthalmoscopy (BIO) in a screening program for retinopathy of prematurity (ROP). METHODS: Observational comparative study with prospective data collection. Examinations with RetCam (n=169) were performed on 83 infants included in a screening program for ROP and stored for analysis at a later stage. An experienced ophthalmologist examined the ocular fundus with binocular indirect ophthalmoscopy (BIO). The RetCam images were assessed for the presence of ROP, zone, grade, and presence of plus disease. RetCam and BIO data were compared by visually to estimate sensitivity, specificity, positive (VPP) and negative (VPN) predictive values. RESULTS: ROP disease was detected in 108 eyes with BIO, and in 74 with RetCam. Out of 306 eyes examined with RetCam, false negative results were found in 34 eyes, with no false positives. Sensitivity of RetCam exam vs. BIO was 0.68, and specificity was 0.99. Positive predictive value was 0.93 and negative predictive value was 0.85. All 34 ROP cases not detected with RetCam were in zone III or outer zone II. They were all mild and regressed spontaneously. No threshold ROP was missed with RetCam. CONCLUSION: Binocular indirect ophthalmoscopy is the reference method for the diagnosis of ROP. RetCam may be used as an alternative for ROP screening.

[Developmental centered care. Situation in Spanish neonatal units]. / Cuidados centrados en el desarrollo. Situación en las unidades de neonatología de España.

INTRODUCTION: Developmental centered care (DC) is focused on sensorineural and emotional development of the newborns. In Spain we have had information on the application of DC since 1999, but the extent of actual implementation is unknown. OBJETIVE: To determine the level of implementation of DC in Spanish neonatal units where more than 50 infants weighing under 1500g were cared for in 2012. A comparison was made with previous data published in 2006. MATERIAL AND METHODS: A descriptive observational cross-sectional study was performed using a survey with seven questions as in the 2006 questionnaire. RESULTS: The survey was sent to 27 units. The response rate was 81% in 2012 versus 96% in 2006. Noise control measures were introduced in 73% of units in 2012 versus 11% in 2006 (P<.01). The use of saccharose was 50% in 2012 versus 46% in 2006 (P=.6). Parents free entry was 82% in 2012 versus 11% in 2006 (P<.01). Kangaroo care was used without restriction by 82% in 2012 compared to 31% in 2006 (P<.01). CONCLUSIONS: The implementation of the DC in Spain has improved. There is still room for improvement in areas, such as the use of saccharose or noise control. However, it is important to highlight the positive change that has occurred in relation to unrestricted parental visits.

[Study of anxiety levels in neonatal unit staff]. / Estudio de los niveles de ansiedad en los profesionales de una unidad neonatal.

INTRODUCTION: The professionals who routinely work in neonatal units become under stress due to the working conditions and the nature of the tasks carried out. As a consequence of this, they may have high levels of anxiety. Anxiety is defined as an emotional response or response patterns that include cognitive, physiological and behavioural aspects. METHODS: A prospective cross-sectional study was conducted on all neonatologist, nurses and care assistants who were given two self-administered questionnaires under baseline conditions, to assess Sate Anxiety and Trait Anxiety. (IDDA-EA; STAI, State-Trait Anxiety Inventory). RESULTS: The response rate was 88.5%, and 36% scored between 30 and 70 percentiles on State Anxiety, with 11.8% above the 70 percentile and 51% below the 30 percentile. There were no significant differences in relation to occupation or age. There were also no significant differences between State and Trait Anxiety. Regarding gender, it has obtained A statistically significant difference of 8 points higher was obtained for women. CONCLUSIONS: For the majority professionals everyday situations in which are involved do not significantly raise the burden of anxiety, as half of them have levels below the average. They perceive themselves as competent and able to cope with their tasks. They have a high degree of interest and attention in the activities performed.

Prospective study in critically ill non-neutropenic patients: diagnostic potential of (1,3)-ß-D-glucan assay and circulating galactomannan for the diagnosis of invasive fungal disease.

Diagnosis of invasive fungal disease (IFD) in patients under intensive care is challenging. Circulating biomarkers, (1,3)-ß-D-glucan (BG) and galactomannan (GM), were prospectively assessed in 98 critically ill patients at risk of IFD. There were 11 cases of invasive aspergillosis (IA; 4 proven and 7 probable), 9 cases of proven invasive candidiasis (IC), 1 case of mixed proven IC and probable IA, 1 case of proven zygomycosis, and 1 case of mixed mycelial proven IFD. In all IA cases there was no significant difference when the area under the receiver operating characteristic curve (AUC) of GM (0.873 [95%CI, 0.75-0.99]) and BG (0.856 [95% CI, 0.71-0.99]) were compared (p = 0.871). The AUC for BG in IC and for the rest of the IFD cases was 0.605 (95% CI, 0.39-0.82) and 0.768 (95% CI, 0.63-0.90) respectively. Positive BG (40%) predated blood culture (n = 3) and abdominal pus (n = 1) a mean of 3.25 days before Candida was grown. In patients with IFD caused by molds, BG appeared a mean of 5.65 days before culture results. For the diagnosis of patients at risk of IC, BG has shown a high NPV (94.5%), with positive results also predating blood cultures in 30% of patients. In conclusion, early BG results permit a timely initiation of antifungal therapy in patients at risk of IFD.

Comparative study of the Weil osteotomy with and without fixation.

BACKGROUND: Weil osteotomy is a technique widely used in patients with metatarsalgia which shortens the metatarsal and reduces the load under the metatarsal head. METHODS: The aim of this paper is to compare the results of the Weil osteotomy with and without any fixation system. We present a retrospective study of 92 patients (97 feet) who underwent treatment for metatarsalgia between 1999 and 2005. One hundred and six osteotomies were vixed using a screw amd no fixation was used in 92. The mean follow-up was 51.2 and 46.6 months respectively. RESULTS: All the patients were evaluated following the AOFAS LMIS scale, obtaining a mean score of 69.8 points (ranged 15-100) and 75.3 points (from 47 to 100) in each group (P=0.11). CONCLUSIONS: The results of fixed and unfixed Weil osteotomies were not significantly different. Our study could not find a significant relationship between metatarsal shortening and main complications (recurrent metatarsalgia, transfer metatarsalgia and stiffness of the metatarsophalangeal joint).

[Ages of sitting up and walking in preterm newborns less than 1,500 G with bronchopulmonary dysplasia]. / Edades de sedestación y marcha en recién nacidos pretérmino menores de 1. 500 gr con displasia broncopulmonar.

INTRODUCTION: Adverse neurological events in very low birth weight (VLBW) children with bronchopulmonary dysplasia (BPD) are more frequent than in children without. An understanding of the ages when preterm infants acquire certain motor skills will give parents more appropriate information on motor development. The objective of the present study is to estimate the influence between BPD and the age of acquisition of sitting unsupported and independent walking in VLBW children with normal neurological examination at 2 years of corrected age. PATIENTS AND METHODS: A longitudinal study was conducted on a cohort of 885 children with VLBW, admitted to the Hospital "12 de Octubre" between January 1991 and December 2003. Age for both skills was established by interview with parents. Means were compared with t-test and Bonferroni adjustment where appropriate. RESULTS: Both motor skills were acquired later in the group with BPD (7.8±2m vs. 7.1±1.3m for sitting unsupported and 14.5±3.8m vs. 13.4±2.5m for walking) (P<.001). BPD was associated with delayed acquisition (above p90) of these skills, OR=2.6 (1.6-4.1) for sitting and OR=2.8 (1.6-4.8) for walking. Association was found after adjusting for gestational age (GA) and weight. CONCLUSION: BPD was associated with delayed acquisition of both skills in VLBW children with normal neurological examination at 2 years.

[Congenital cataracts: complications and functional results according to different surgical techniques]. / Cataratas congénitas: complicaciones y resultados funcionales según diferentes técnicas quirúrgicas.

PURPOSE: To evaluate visual results, refractive error and complications in a series of congenital cataracts treated with different surgical techniques. METHODS: Retrospective review of 51 eyes with congenital cataracts which were surgically treated between 1989 and 2005. Eleven were unilateral cataracts and 40 were bilateral cataracts. Thirty-three eyes were treated with a primary intraocular lens (IOL) and 18 were aphakic eyes. RESULTS: The best outcomes were observed in bilateral cataracts and in those that received early primary IOL. Three eyes achieved 0.8-1, two eyes achieved 0.6-0.7. All of them were eyes with primary IOL. Seventeen percent of unilateral cataracts and 23.8% of bilateral cataracts achieved 0.4 or better. The most serious complication was visual axis opacification (VAO), 27 of 51 eyes developed VAO. Fifty percent of eyes with primary IOL and 63% of aphakic eyes developed VAO. The VAO developed sooner in the IOL group (6.5 months on average). There was a high myopic shift in 3 eyes. There was a significantly greater myopic shift in the unilateral cases. CONCLUSIONS: The best acuities were achieved in the eyes which had been treated with early primary IOL, but they had a higher rate of complications (VAO), thus requiring reoperation. Final refraction in the unilateral group was significantly more myopic than in the bilateral group.

Age of sitting unsupported and independent walking in very low birth weight preterm infants with normal motor development at 2 years.

AIMS: The aims of this study is to (i) determine the age of sitting unsupported and independent walking in preterm infants with birth weight under 1500 g (very low birth weight, VLBW); (ii) estimate differences between VLBW children and a reference population and (iii) estimate the association between clinical characteristics and late age at sitting and walking. METHODS: A longitudinal study was conducted of a cohort of 876 children with VLBW. The World Health Organization (WHO) motor development study population was used as a reference. Ages for both skills were established by interview with parents. Means were compared with t-test, ANOVA and Bonferroni adjustment where appropriate. RESULTS: The inclusion criteria were complied with 694 patients; 50% of VLBW sat at 7 m corrected age (CA) and walked at 13 m CA. Both motor skills were acquired later (7.3 +/- 1.5 and 13.6 +/- 2.8 m) compared with the control group (6 +/- 1.1 and 12.1 +/- 1.8 m). Weight or head circumference at birth below the 10th percentile or the presence of bronchopulmonary dysplasia were associated with delayed acquisition of both skills. CONCLUSION: Very low birth weight infants typically sit unsupported and walk later than term infants. Tables describing reference values for milestones acquisition for different categories of infants (gestational age, birth weight and other determinants) may contribute to inform the decision making process on access to available resources.

[Reticulocyte haemoglobin content in the diagnosis of iron deficiency]. / Contenido de hemoglobina reticulocitaria para el diagnóstico de la ferropenia.

INTRODUCTION: The detection of iron deficiency is essential in order to start early treatment to prevent long-term systemic complications of iron deficiency anaemia. Reticulocyte haemoglobin content (CHr) has been shown to be a helpful indicator for detecting iron deficiency before the development of anaemia. The objectives of this study were to evaluate the efficiency of CHr in the assessment of iron deficiency with or without anaemia and to determine the cut-off value with the best diagnostic yield. STUDY DESIGN: A descriptive cross-sectional study was carried out on an urban population of both sexes aged 6 months to 14 years. The study protocol included a questionnaire and taking a venous blood sample for a complete blood cell count with CHr and biochemical indicators of iron status. RESULTS: Samples were obtained for 237 children. A CHr cut-off value of 25 pg had an overall sensitivity of 90.7% and specificity of 80.1% for the diagnosis of iron deficiency with or without anaemia. The value of CHr was below 25 pg in the diagnostic groups with iron deficiency and iron deficiency anaemia, and above this value in the diagnostic groups with non-iron deficient anaemia or normal. CONCLUSIONS: CHr is a useful hematological marker to identify iron deficiency and iron deficiency anaemia in childhood. A CHr value of 25 pg showed the best performance to identify iron deficiency with or without anaemia.

[Review of haematology and biochemistry parameters to identify iron deficiency]. / Revisión de los parámetros hematológicos y bioquímicos para identificar la ferropenia.

INTRODUCTION: There has been a continuous improvement in the methods to detect iron deficiency, a common condition in children, in the last decades or so, but it is still difficult to establish which parameters should be included in a diagnostic panel for iron deficiency and iron deficiency anaemia. The objectives of this study were to evaluate the diagnostic efficiency of commonly used haematological and biochemical markers, as well as the reticulocyte haemoglobin content (CHr) in the diagnosis of iron deficiency with or without anaemia. STUDY DESIGN: A descriptive cross-sectional study was carried out on an urban population of both sexes aged 6 months to 14 years. A complete blood cell count with CHr was obtained. Biochemical markers of iron metabolism, transferrin saturation, serum iron, ferritin and total iron binding capacity were also measured. RESULTS: Samples were obtained for 237 children. A multiple stepwise logistic regression analysis identified CHr and iron serum as the only parameters independently associated to iron deficiency (P<0.05). CHr was the strongest predictor of iron deficiency and iron deficiency anaemia. CONCLUSIONS: Our study indicates that the measurement of CHr may be a reliable method to assess deficiencies in tissue iron supply. CHr together with a complete blood count may provide an alternative to the traditional biochemical panel for the diagnosis of iron deficiency in children.

[Evaluation of pain in a neonatal intensive care unit during endocrine-metabolic tests]. / Valoración del dolor en la unidad de cuidados intensivos neonatales durante la extracción de las pruebas endocrinometabólicas.

OBJECTIVES: To determine whether the pain suffered during the endocrine metabolic test can be lowered by adding skin to skin care to the use of sucrose. To establish factors that may modify the feeling of pain and evaluate the parents opinion during the extraction. PATIENTS AND METHODS: Controlled clinical trial. Two groups: group 1 (n= 27), skin to skin and sucrose, and group 2 (n=27), sucrose. The pain was measured with the Neonatal Infant Pain Scale (NIPS) during the endocrine metabolic test. Patients on mechanical ventilation, with HIV III or IV and those who had been given sedative analgesics in the previous 24 hours were excluded. RESULTS: The average gestational age in group 1 was 35.1 +/- 3.5 weeks and 35.4 +/- 3.2 weeks for group 2. The NIPS in group 1 was 2.51 +/- 1.42 and 2.81 +/- 2.11 (NS) in group 2. On only one occasion was severe pain noticed (group 2). There was a tendency towards a higher NIPS with a higher gestational age (r=0.19) and a lower number of previous capillary (r= -0.06) and venous (r= -0.11) extractions. Group 1 parents thought that this practice contributed to decreasing their children's irritability and increased their trust in the care team. CONCLUSION: By adding skin to skin care to the sucrose during the endocrine metabolic test does not relieve the pain feeling. Parents in the skin to skin group thought that this practice contributed to decreasing their children's irritability and increased their trust in the care team.

[EuroNeoStat: a European information system on the outcomes of care for very-low-birth-weight infants (< 1500 g)]. / EuroNeoStat: ein Europäisches Informationssystem zur erfassung der behandlungsergebnisse von sehr untergewichtigen Frühgeborenen mit einem Geburtsgewicht < 1500 g.

BACKGROUND: Prematurity rates are increasing throughout the world. Despite an overall rather small percentage of very low birth weight infants (VLBWI), which is approx. 1-2 % in most countries, these infants contribute significantly to morbidity and neonatal and infant mortality rates. METHODS: EuroNeoStat was initiated as an European information system on the outcomes of VLBWI to monitor and improve the care of these infants throughout Europe. EuroNeoStat includes an initiative, called EuroNeoSafe, to promote the safety of these high risk preterm infants. Perinatal and neonatal data from VLBWI is collected without using data that identify individuals or institutions. These data is analyzed at the coordination center in Bilbao. All institutions taking care on VLBWI in Europe can participate in this network and will be able to compare their own outcome data with other institutions from the network. Information on EuroNeoStat and the current data set is available on www.euroneostat.org. CONCLUSION: Successful initiatives aiming at improving outcomes in perinatal and neonatal care require collaborative networking, an attitude of constructive criticism and thorough comparative analysis of the outcomes and incidents in the health-care process.

[Tolerability, safety, and efficacy of sodium phosphate preparation for colonoscopy: the role of age]. / Tolerancia, seguridad y eficacia de la preparación para colonoscopia con fosfato de sodio: el papel de la edad.

OBJECTIVES: To compare subjective tolerance and secondary adverse events to bowel cleansing prior to colonoscopy with polyethylene glycol (PEG) and sodium phosphate (NaP) in adult patients and in those 65 or more years old. MATERIAL AND METHODS: Retrospective matched study, choosing 140 patients among all of those who underwent colonoscopy from March 2004 to May 2005. We investigated the presence of the next adverse events during bowel preparation: Fever, low digestive bleeding, abdominal pain, perianal pain, nausea, vomiting, thirst, somnolence, agitation, tremor and convulsions. We considered bad objective tolerance if the patient presented any one of these events. We also asked patients about subjective tolerance to preparation. RESULTS: Seventy patients prepared with PEG and seventy with NaP were included (69 women and 71 men, mean age 60.6 +/- 14.8 years). There was no relationship between subjective tolerance or the presence of adverse events and bowel cleansing with any of the products in general population or in elderly patients (p = 0.09 and p = 0.45 in the elderly). However, patients prepared with NaP showed more nausea than those who employed PEG (p < 0.009), overall women of 65 or more years old. There were no severe adverse events in patients prepared with NaP. Elderly showed better tolerance than younger patients, and women worst tolerance than men, irrespective of the lavage preparation employed. Patients prepared with PEG unfinished bowel cleansing more frequently than those with NaP. Cleanliness achieved with NaP was significantly better than that obtained with PEG. CONCLUSIONS: Bowel cleansing prior to colonoscopy with NaP is as well tolerated, safe and effective as with PEG, even in elderly healthy patients, although it causes more nausea. Cleanliness with NaP is better than that achieved with PEG.

[Retinopathy of prematurity screening in Spanish neonatal units]. / Cribado de la retinopatía de la prematuridad en las unidades neonatales españolas.

INTRODUCTION: A wide variety of retinopathy of prematurity (ROP) screening criteria exists in the different hospitals. In 1988, the benefits of cryotherapy treatment in severe ROP cases were demonstrated, and since then, some scientific societies have made recommendations on the screening and treatment of ROP. Within the Spanish scientific community, there are no specific recommendations on screening, diagnosis or treatment. OBJECTIVES: To describe the criteria used in the screening of retinopathy in premature newborns by those Spanish hospitals caring for babies with birth weights below 1,500 g. MATERIAL AND METHOD: A cross-sectional study was performed based on a 50 question questionnaire on screening criteria and other related issues. This questionnaire was sent to those public and private neonatal units in Spain caring for babies with birth weights below 1,500 grams. The questionnaire was sent and returned between January 2002 and May 2003. RESULTS: Units in all of the 17 autonomous communities and both autonomous cities in territorial Spain (Ceuta and Melilla) responded. There was a 90% response rate. All the participating hospitals perform ROP screening. Only 62.9% of the hospitals follow a written protocol on screening. A large majority of hospitals (79.8%) perform a retinal eye examination on all newborns below 1500 g at birth. Half of the hospitals included in the study, 51.6%, determine the cut-off point for performing the screening at 32 weeks of gestational age. Around 73% of the hospitals include the administering of oxygen supplements to premature babies as part of the criteria for screening, regardless of the babies' weight and gestational age. Weight, gestational age and oxygen are the only criteria used in 51% of the units. That all hospitals in Spain should establish some screening criteria was suggested by 90% of the responses. Only 10% use analgesia or sedation, other than topical, when examining the retina. CONCLUSIONS: Even though all the hospitals participating in the study screen for ROP, there is little agreement on which criteria should be followed when screening and on other aspects related to its practice.

[Cerebral palsy: the concept and population-based registers]. / Parálisis cerebral: concepto y registros de base poblacional.

INTRODUCTION: Cerebral palsy (CP) is the most common cause of motor disability in the paediatric age. For several decades, a number of developed countries have kept registers that have been used to conduct population-based studies of CP. In Spain, however, little attention has been paid to the epidemiology of CP. AIM: To review the concept of CP today and to stimulate greater interest in researching into CP based on the experience of other countries. DEVELOPMENT: The different definitions of CP cover motor sequelae secondary to an isolated brain injury that occurs in a developing brain. CP registers were started as a means of monitoring the prevalence of CP and planning suitable care for patients. Over the last decade projects have been carried out that involve the coordinated efforts of several centres; this provides a larger population for study and reduces the chances of confusion with respect to the terminology employed. In this regard, one notable line of work is that of the European CP group (SCPE), which gathers information about children with CP in 15 countries. Spain has been taking part in this project since 2003 through a group of researchers from the Hospital 12 de Octubre in Madrid. CONCLUSIONS: From the very definition of the disorder, CP is a complex condition. A population-based study of CP in Spain should help to arouse a renewed interest in this condition in our country.

[Pediatric cataracts: epidemiology and diagnosis. Retrospective review of 79 cases]. / Cataratas pediátricas: estudio epidemiológico y diagnóstico. Análisis retrospectivo de 79 casos.

PURPOSE: To determine the epidemiology, diagnosis and treatment features in a group of pediatric patients with cataracts treated at our hospital. The aim was to improve the visual prognosis in these patients. METHODS: 79 children with cataracts were reviewed retrospectively during an 18 year period (1986-2004). This involved patients with congenital cataracts and those who acquired them later. Most of the latter group had a traumatic etiology (90%). RESULTS: The etiology of most cataracts was idiopathic (68%) for the congenital group and traumatic (90%) for the acquired group. Congenital cataracts were frequently nuclear in type (31%) with 56% being bilateral. 27% of the congenital group were associated with dysmorphic eye features, the most frequent being microphthalmos. The most frequent presenting feature was leucokoria, seen in 44% of patients. 75% of congenital cataracts were diagnosed within one month of clinical manifestation. 58% of the congenital cataracts were treated by surgery and 50% of these were performed within one month of the diagnosis. 90% of the acquired cataracts were treated surgically, and 95% of these were performed less than one month after diagnosis. CONCLUSIONS: We attained a prompt diagnosis and treatment in a high percentage of cases. Prompt diagnosis and treatment will determine the visual prognosis of these patients. We must continue trying to shorten this period of time in order that all children with this condition are diagnosed and treated urgently and efficiently.

Cataratas pediátricas: estudio epidemiológico y diagnóstico. Análisis retrospectivo de 79 casos / Pediatric cataracts: epidemiology and diagnosis. Retrospective review of 79 cases

Objetivo: Determinar las características epidemiológicas, diagnósticas y terapéuticas de un grupo de cataratas de nuestro medio con el propósito de mejorar el pronóstico visual de estos pacientes. Métodos: Estudio retrospectivo de 79 casos de cataratas pediátricas durante un periodo de 18 años (1986-2004). Hemos diferenciado dos grupos etiológicos de trabajo: cataratas congénitas y cataratas adquiridas. Resultados: La causa más frecuente entre las congénitas fue la idiopática (68%) y la más frecuente de las adquiridas fue traumática (90%). La morfología más frecuente de las congénitas fue la nuclear 0,31 (31%). El 56% de las cataratas congénitas fueron bilaterales. El 27% de las cataratas congénitas se asociaban a otras anomalías oculares y la más frecuente fue el microftalmos. El signo clínico de presentación más frecuente de las cataratas congénitas fue la leucocoria, en 0,44 (44%). El 75% (0,75) de las cataratas congénitas de nuestro medio tardan menos de un mes en diagnosticarse desde la manifestación clínica. El 58% (0,58) de las cataratas congénitas se trataron con cirugía y el 50% de ellas tardaron menos de 1 mes en operarse. El 90% (0,9) de las adquiridas se trataron con cirugía y el 95% de ellas tardaron menos de un mes en operarse. Conclusiones: En nuestra serie conseguimos un diagnóstico y tratamiento precoz en un alto porcentaje de pacientes. El pronóstico visual de estos niños viene determinado por la precocidad en el diagnóstico y el tratamiento, es por ello que debemos continuar intentando acortar este período de tiempo y conseguir que todos los niños sean diagnosticados y tratados precozmente
