Ultrasound measurement of anatomical parameters of the upper airway in adults. / Medición ecográfica de parámetros anatómicos de la vía aérea superior en adultos.

BACKGROUND: Most of the works on ultrasound airway anatomy are limited to a morphological description. A study was conducted in order to provide an objective normal range of measurements. MATERIALS AND METHODS: Observational study to describe the ultrasound characteristics of the upper airway in adults without clinical difficult airway criteria, compared to cadaver dissection anatomical models. RESULTS: The study included 45 volunteers (27 men and 18 women), and 3fresh cadavers. The quality of the examination was very good/good in 93% of the cases. MEASUREMENTS: tracheal diameter (1.3±0.3cm), vocal cord (1.6±0.5cm), cricothyroid membrane (0.94±0.32cm), cricotracheal membrane (0.3±0.09cm), thickness of the muscles in the floor of the mouth (MFM) (1.5±0.26cm), sub-mandibular subcutaneous fat plus MFM (2.11±0.34cm), hyoid-mandible distance (5.35±0.69cm), palate-floor of the mouth distance (4.92±0.5cm), palate-anterior border of the mandible (5.51±0.7cm), and palate-pharynx angle (114±14). Observed differences: Males had a larger tracheal diameter than females (M: 1.4±0.3 vs. F: 1.2±0.2cm, p=0.014). Subject height showed a significant correlation with the tracheal diameter (R: 0.501, p<0.001), as well as the length of the vocal cord (R: 0.363, p=0.016), the thickness of MFM (R=0.299, p=0.046) as well as the hyoid-mandible (R: 0.556; p<0.001) and palate-mandible distances (R: 0.362; p=0.015). CONCLUSIONS: Ultrasound allows the anatomy of upper airway to be evaluated, as well as to calculate distances between the anatomical structures. The study defines these distances in adult volunteers without clinical difficult airway criteria.

Outpatient intravenous multimodal elastomeric pump with methadone in ambulatory surgery. / Analgesia multimodal domiciliaria con metadona en perfusión intravenosa mediante bomba elastomérica en cirugía mayor ambulatoria.

BACKGROUND AND OBJECTIVE: Analgesia in Ambulatory Surgery (AS) needs to evolve in parallel with surgical complexity. We designed a study to try to improve analgesia in painful surgery using an intravenous elastomeric pump. As a novelty, methadone was included. PATIENTS AND METHODS: An observational study, physical status ASA I-II, underwent ambulatory surgeries with moderate-severe postoperative pain. Analgesia was administered for 48h by an intravenous multimodal elastomeric pump (methadone, tramadol, dexketoprofen and ondansetron at low doses). Visual Analogue Scale (VAS) at rest and movement were evaluated at 24 and 48h. Andersen Scale, Lattinen Test, rescue analgesia and side-effects were recorded at 24h after surgery. RESULTS: We included 73 patients: 37% abdominal wall surgery, 30% hemorrhoidectomies and 33% perineal surgery. Median VAS score at rest and movement were 0 and 3 at 24h, and 0 and 2 at 48h. At 24h, Andersen's Scale score was ≤1 in 89%, and Lattinen Test ≤6 in 90% of patients. Rescue medication was administered in 30% of patients. Two patients had vomiting at 24 and 48h. Minor catheter and pump dysfunctions were observed in 8% of patients. CONCLUSIONS: Multimodal analgesia with intravenous methadone administered by elastomeric perfusion at home is effective and safe. However, monitoring is needed to diagnosis dysfunction of devices.

[Spontaneous expulsive choroidal hemorrhage. Case report]. / Hemorragia coroidea expulsiva espontánea. Caso clínico.

CLINICAL CASE: A case is presented of an 85-year-old woman living in a geriatric residence, who was admitted to the emergency department of our hospital with a spontaneous expulsive choroidal hemorrhage in her left eye. There was no a history of ophthalmic disease, and the patient only reported having intracapsular cataract surgery in both eyes 25 years ago, and that she also became blind in her left eye in the past few years. DISCUSSION: Non-surgical spontaneous expulsive choroidal hemorrhage is a very rare and disastrous clinical event. The predisposing factors involved are: advancing age, vascular illness (especially atherosclerosis), glaucoma, and severe corneal damage.

Factors predicting distress among parents/caregivers of children with neurological disease and home enteral nutrition.

BACKGROUND & AIMS: Caregivers of children with chronic diseases included in a home enteral nutrition (HEN) programme are at risk of experiencing a feeling of burden, high level of anxiety and psychological distress. The aims of this study were: first, to examine the prevalence of symptoms of anxiety-depression in caregivers of children with neurological diseases requiring HEN by gastrostomy tube (GT); second, to compare the characteristics of caregivers with high or low risk of exhibiting symptoms of anxiety-depression; and third, to investigate possible associations to child disease severity and nutrition support mode. METHODS: A cross-sectional observational study was performed in 58 caregivers of children (31 boys, aged 0.3-18 years) with neurological diseases and GT feeding. The characteristics of caregivers with high or low risk of presenting symptoms of anxiety-depression were compared regarding the following variables: socio-demographic characteristics, the primary caregiver's intrapsychic factors, anthropometric parameters of the child, length of HEN, type of nutrients delivered by GT and infusion regime. RESULTS: All primary caregivers were mothers. Fifty-three per cent of them showed high risk of exhibiting symptoms of anxiety-depression. Mothers with high or low risk of presenting symptoms of anxiety-depression were comparable in age and family socio-economic status. They were also similar in terms of age, anthropometric conditions and length of HEN in their children.No differences were found between the two groups of mothers according to the level of the child's motor function impairment, type of nutrients delivered by GT and infusion regime. Higher levels of psychological distress and perception of burden overload were found in mothers with high risk of exhibiting symptoms of anxiety-depression. CONCLUSIONS: This study found a high prevalence of symptoms of anxiety-depression, perception of burden overload and psychological distress in caregivers of children with HEN. Thus, greater practical and emotional support is required for these families.

Analysis of the Spanish national registry for pediatric home enteral nutrition (NEPAD): implementation rates and observed trends during the past 8 years.

BACKGROUND/OBJECTIVES: The home enteral nutrition (HEN) provides nutritional support to children with chronic diseases who are nutritionally compromised and allows them to be discharged more quickly from hospitals. In 2003, a web-based registry (Nutrición Enteral Pediátrica Ambulatoria y Domiciliaria, Pediatric Ambulatory and Home Enteral Nutrition -NEPAD-) was created with the objective of gathering information about pediatric HEN practices in Spain. AIM: The aim of this study was to report the implementation of the NEPAD (Nutrición Enteral Pediátrica Ambulatoria y Domiciliaria, Pediatric Ambulatory and Home Enteral Nutrition) registry of pediatric HEN in Spain and to analyze data evolution trends from 2003 to 2010. SUBJECTS/METHODS: The data from the Spanish NEPAD registry were analyzed according to the following variables: demographic data, diagnosis, indication for HEN, nutritional support regime and administration route. RESULTS: Over the study period, 952 patients (1048 episodes) from 20 Spanish hospitals were included in the NEPAD registry. The most frequent indication for HEN was decreased oral intake (64%), and neurological disease was the most prevalent illness. HEN was delivered via a nasogastric tube in 573 episodes (54.7%), by gastrostomy in 375 episodes (35.8%), oral feeding in 77 episodes (7.3%) and by jejunal access in 23 episodes (2.2%). Significant differences in the mode of administration were observed based on the pathology of the child (χ(2), P<0.0001). The cyclic feeding was the most widely used technique for the administration of HEN. Most of the patients used a pump and a polymeric formula. Transition to oral feeding was the primary reason for discontinuation of this type of support. CONCLUSIONS: Since the NEPAD registry was established in Spain, the number of documented patients has increased more than 25-fold. Many children with chronic illness benefit from HEN, mainly those suffering from neurological diseases.

Psychometric properties of the structured Satisfaction Questionnaire with Gastrostomy Feeding (SAGA-8) for caregivers of children with gastrostomy tube nutritional support.

BACKGROUND: To analyse the psychometric properties of the structured Satisfaction Questionnaire with Gastrostomy Feeding (SAGA-8) in parents/caregivers of children with home enteral nutrition (HEN) by gastrostomy tube (GT). METHODS: Eighty-six caregivers (mothers) of paediatric patients with HEN by GT were recruited. Patients suffered from neurological disease (61.6%) and other chronic diseases. The SAGA-8 scale, a structured questionnaire to explore satisfaction with HEN by GT, and the Caregiver Burden Inventory (Zarit) were completed. The discriminating power of each of the SAGA-8 items, internal consistency and external validity were evaluated. An exploratory factor analysis and Kaiser-Meyer-Olkin (KMO) was performed as well. RESULTS: Eighty-four percent of the families expressed high satisfaction with GT feeding. All eight items of SAGA-8 gave additional information. The exploratory factor analysis revealed that a significant part of the items' variability could be explained by two independent factors: Factor 1 (direct benefit), which compiled the variables related to the perception of children's overall improvement by GT feeding; Factor 2 (indirect benefit), which grouped the variables related to a decrease in respiratory infections, feeding time and institutional support. Results from KMO (0.628) indicated the high adequacy of the items assessed in the factorial analysis. Moreover, the questionnaire presented high internal consistency (0.76), and the external validation analysis confirmed the correlation between SAGA-8 and Zarit, thereby emphasising the approptiate use of the SAGA-8 to detect carers' satisfaction. CONCLUSIONS: The SAGA-8 questionnaire has a high discriminatory power to assess the degree of satisfaction experienced by parents/caregivers of children with HEN by GT and, subsequently, the patients' wellbeing.

[Epidemiological study of the metabolic diseases with homocystinuria in Spain]. / Estudio epidemiológico de las enfermedades metabólicas con homocistinuria en España.

OBJECTIVES: To determine the prevalence of homocystinuria in Spain and to establish the measures and mechanisms to ensure its prevention, diagnosis and treatment. MATERIAL AND METHODS: A national cross-sectional survey was conducted by means of a questionnaire sent to 35 hospitals in which children and adult patients are treated. RESULTS: Using the questionnaires submitted by 25 physicians from 16 centres, 75 patients were identified: 41 transsulphuration defects (one deceased), 27 remethylation (six deaths) and 7 without a syndromic diagnosis. The age at diagnosis varied widely, and 18 cases had more than one sibling affected. The more severe clinical manifestations involved the patients with remethylation defects. There was a high percentage of cognitive impairment, followed by lens diseases. Almost half of the patients had neurological disorders. There was increased vascular involvement in CBS-deficient adults. The therapeutic options most used were, folic acid, hydroxycobalamin and betaine. CONCLUSIONS: In view of these results and especially the small number of CBS deficiencies detected, we conclude that there is a need to introduce newborn screening for classical homocystinuria and ensure implementation of an appropriate diagnostic workup in all patients at risk.

Consensus on paediatric enteral nutrition access: a document approved by SENPE/SEGHNP/ANECIPN/SECP.

Standardization of clinical procedures has become a desirable objective in contemporary medical practice. To this effect, the Spanish Society of Parenteral and Enteral Nutrition (SENPE) has endeavoured to create clinical practice guidelines and/or documents of consensus as well as quality standards in artificial nutrition. As a result, the SENPE´s Standardization Team has put together the "Document of Consensus in Enteral Access for Paediatric Nutritional Support" supported by the Spanish Society of Pediatric Gastroenterology, Hepatology and Nutrition (SEGHNP), the National Association of Pediatric and Neonatal Intensive Care Nursery (ANECIPN), and the Spanish Society of Pediatric Surgery (SECP). The present publication is a reduced version of our work; the complete document will be published as a monographic issue. It analyzes enteral access options in the pediatric patient, reviews the levels of evidence and provides the team-members' experience. Similarly, it details general and specific indications for pediatric enteral support, current techniques, care guidelines, methods of administration and complications of each enteral access. The data published by the American Society for Parenteral and Enteral Nutrition (ASPEN) and several European Societies has also been incorporated.

Long-chain polyunsaturated fatty acid concentration in patients with inborn errors of metabolism.

INTRODUCTION: Long-chain polyunsaturated fatty acid (LCPUFA) can be provided by diet (fatty fish, eggs, viscera and human milk) or synthetised from essential fatty acids linoleic and α-linolenic acids through the microsomal pathway. However, endogenous LCPUFA synthesis is rather low, especially for docosahexaenoic (DHA), and seems insufficient to achieve normal DHA values in individuals devoid of preformed dietary supply. Inborn errors of metabolism (IEMs) are therefore diseases with a special risk for LCPUFA deficient status. AIM: Our aim was to evaluate LCPUFA status in 132 patients with different IEMs. METHODS: We performed a cross-sectional study of plasma and erythrocyte LCPUFA composition of 63 patients with IEMs treated with protein-restricted diets compared with data from 69 patients with IEMs on protein-unrestricted diets, and 43 own reference values. RESULTS: Erythrocyte and plasma DHA and arachidonic acid concentrations were significantly decreased in patients treated with protein-restriction compared with those on protein-unrestricted diets and with our reference values (p < 0.0001). In the protein-restricted group, 45% of patients showed decreased erythrocyte and plasma DHA values (only 7% and 10%, respectively in the protein-unrestricted group) (p < 0.0001). Erythrocyte and plasma DHA values correlated with the natural protein intake in patients on protein-restriction (r = 0.257; p = 0.045; r = 0.313; p = 0.014, respectively). CONCLUSION: Plasma and erythrocyte DHA concentrations are decreased in patients with IEMs treated with protein restriction. DHA concentration correlates with the patients' protein intake. Supplementation of patients with LCPUFA would have a beneficial influence on their nutritional status.

Home parenteral nutrition in children: procedures, experiences and reflections.

This document summarizes the issues raised in a think-tank meeting held by professionals with expertise in pediatric Home Parenteral Nutrition. This nutritional technology enables patients to return home to their family and social environment, improves their quality of life and decreases health-care costs; however, it is complex and requires an experienced nutritional support team. Patient selection is normally made according to their underlying disease, the estimated duration of support and family and social characteristics. The patient''s family must agree to take on caregiver's responsibilities and should be able to perform treatment safely and effectively after receiving proper training from the nutritional support team. Close monitoring must be carried out to ensure tolerance and effectiveness of nutritional support, thereby avoiding complications. This nutritional treatment achieves, in most cases, recovery and intestinal adaptation in varying periods of time. In certain diseases, and when home parenteral nutrition becomes complicated, intestinal transplant may be recommendable, so referral to rehabilitation units and Intestinal Transplantation should be made early on.

Current status of pediatric home enteral nutrition in Spain: the importance of the NEPAD register.

Home enteral nutrition (HEN) is a type of enteral nutrition (EN) which is becoming progressively more widespread in pediatrics due to the benefits it affords to patients, their families and to reducing hospital costs. However, the true extent of its use is unknown in Spain as the data-base set up for this purpose is still underused (Registro de Nutrición Enteral Pediátrica Ambulatoria y Domiciliaria -NEPAD-). More thorough registration of patients in the NEPAD online register will provide information about the characteristics of HEN in Spain: prevalence, diagnosis, the population sector being administered HEN, complications and developments. Likewise, forecast and planning of the necessary resources could be made while those in use could be analysed.

[Childhood obesity. Recommendations of the Nutrition Committee of the Spanish Association of Pediatrics. Part II. Diagnosis. Comorbidities. Treatment]. / Obesidad Infantil. Recomendaciones del Comité de Nutrición de la Asociación Española de Pediatría. Parte II. Diagnóstico. Comorbilidades. Tratamiento.

[Home enteral nutrition in Spain. Results of the register of the Spanish Society of Pediatric Gastroenterology, Hepatology and Nutrition in 2003]. / Nutrición enteral domiciliaria en España. Resultados del registro de la Sociedad Española de Gastroenterología, Hepatología y Nutrición Pediátrica del año 2003.

INTRODUCTION: The number of children receiving prolonged home enteral nutrition (HEN) is increasing. However, precise information on the incidence and prevalence of HEN in Spain is lacking. Consequently, the Spanish Society of Pediatric Gastroenterology, Hepatology and Nutrition created a patients' register (NEPAD). The aim of the present study was to analyze the results of the first year of the NEPAD register (2003). MATERIAL AND METHODS: The NEPAD is an on-line register that gathers information on the indications for HEN, route of access, type of diet and duration of nutritional support. Quantitative data are expressed as mean and standard deviation, and qualitative data as percentages. RESULTS: In 2003, 124 children from 6 hospitals were registered. The mean age at the beginning of HEN was 3.6 years. The underlying disease was gastrointestinal in 20%, neurological or mental retardation in 20%, cystic fibrosis in 14.5%, tumor in 11%, innate error of metabolism in 10%, congenital cardiac disease in 6%, severe primary malnutrition in 6%, and other causes in 13%. A nasogastric tube was used as the first route of access in 56%, and gastrostomy was used in 42%. Sixty percent of the children received continuous nocturnal enteral nutrition and 90% used an infusion pump. The type of feeding consisted of blenderized natural food in 14%, polymeric pediatric formula in 50%, and infant formulae in 18%. On December 31st, 84 children continued to receive enteral nutrition (68%). CONCLUSIONS: Despite the efforts made to maintain the on-line national register, it has been underused in its first year of existence (2003). Patients with gastrointestinal or neurological diseases constitute the main group of patients in the register. There is a slight preference for the use of nasogastric tube over gastrostomy.

[Brucellar orchiepididymitis]. / Orquiepididimitis por Brucella.

Brucellosis is a cause of human disease, especially in regions whose brucellosis in animals is enzootic. Brucella orchitis is a rare complication of systemic brucellosis (2-14%). Necrotizing orchitis is posible and it must be distinguished from necrotizing involvement arising from other pathogens (TB or Salmonella). Treatment with specific antimicrobial medication helps to avoid unnecessary orchiectomy and prevent infectious disease in the contralateral testis as well as systemic manifestations. We report a case of brucellar epididymo-orchitis presenting as an acute scrotal mass in a 19 years old male who lived in a city. The anamnesis was crucial in the diagnosis of this rare testicular infection. We review the diagnosis and management of this patology.

[Tuberculosis in the Zaragoza province. Estimation by means of the capture-recapture method]. / La tuberculosis en la provincia de Zaragoza. Estimación mediante el método captura-recaptura.

INTRODUCTION: Tuberculosis (TB) is an underreported condition to the Communicable Diseases Control System (CDCS). The objective of this work was to estimate the actual incidence of tuberculosis and the epidemiological characteristics of the diseases in the Zaragoza province. MATERIAL AND METHODS: Retrospective study in which the capture-recapture method was used to estimate the number of tuberculosis cases, by using the microbiology laboratories and the CDSC as data sources. The socio-demographic and clinical characteristics of diagnosed patients throughout three years in this province were analyzed. RESULTS: The mean annual incidence rate of TB was 22.02 per 100,000 inhabitants according to microbiological data, and 48.5 per 100,000 according to the capture-recapture method. A total of 569 patients were studied, and 400 of them were males (70.3%). The mean age was 43.2 years, and the 25-34 year-old group had the highest number of cases (27.9%). Twenty-three percent of cases were co-infected with HIV, and 77.4% were parenteral drug abusers, and 4.4% immigrants. CONCLUSIONS: The capture-recapture method has demonstrated to be useful to know the relevance of TB in our setting. The actual incidence of tuberculosis was higher than that pointed out by the CDCS. Relevant differences were observed regarding incidence rates by age and sex groups. HIV infection and immigration do not appear to explain the frequency of this disease in our setting.

[Acute Gastroenteritis in hospitalized children. 14-Year evolution]. / Gastroenteritis aguda en pacientes hospitalizados. Estudio evolutivo de 14 años.

OBJECTIVES: To analyze the etiology and evolution of patients with acute gastroenteritis hospitalized in our pediatric department and to study the clinical and laboratory differences between acute viral and bacterial gastroenteritis. PATIENTS AND METHODS: We studied the children with a diagnosis of acute gastroenteritis, aged between 0 and 14 years, who were consecutively admitted between 1987 and 2000. Differences were considered statistically significant if p < 0.05. RESULTS: A total of 2,613 patients diagnosed with acute gastroenteritis were hospitalized (10.4 % of hospital admissions). The most common pathogens isolated were rotaviruses (46.5 %), followed by Salmonella (32.6 %) and Campylobacter (19.3 %). Hospital admissions due to Salmonella (p < 0.0001), other bacteria (Escherichia coli and Shigella) (p < 0.002) and adenoviruses (p < 0.01) significantly decreased. Rotaviruses were the most frequently detected pathogens in winter and in children aged less than 1 year (p < 0.0001). The incidence of Salmonella spp was greater in summer and in children older than 2 years (p < 0.0001). The incidence of hyperthermia (rectal temperature higher than 38.5 degreeC) (p < 0.0001), dehydration (p < 0.0005) and fecal blood (p < 0.0001) was higher in bacterial diarrheas. Erythrocyte sedimentation rate (p < 0.001) and leukocyte counts were higher in bacterial gastroenteritis (p < 0.01). CONCLUSIONS: Rotaviruses were the most frequently isolated enteropathogens. The features that best distinguished between bacterial and viral diarrhea were hyperthermia and fecal blood. Hospital admissions due to Salmonella Shigella E. coli, and adenoviruses significantly decreased.

[Ruptured aneurysm of the sinus of Valsalva in a boy with ventricular septal defect]. / Rotura de aneurisma del seno de Valsalva en un niño con comunicación interventricular.

Aneurysmal dilatation of the sinus of Valsalva is a rare structural cardiac abnormality in children. It appears to be more common in Asia. It may be clinically silent for many years but these defects frequently coexist with other cardiac malformations, causing, when rupture occurs, unexpected symptoms that are not explained by the original defects. We report a case of ruptured aneurysm of the sinus of Valsalva in a 12-year-old boy diagnosed with ventricular septal defect in the neonatal period with an uneventful course. The boy suddenly developed acute prechordal pain, symptoms of low heart output and systolic-diastolic murmur. The diagnosis of ruptured aneurysm of the sinus of Valsalva was based on echocardiography. Surgical treatment was required to close the ventricular septal defect and repair the aorta, without valvular replacement. The postoperative course was uneventful. We conclude that is extremely important to have a degree high suspicion of this entity in previously asymptomatic children, with or without cardiac anomalies, who suddenly present this kind of heart failure and abrupt changes in cardiac auscultation.
