Situación actual de la intolerancia a la lactosa en la infancia
La Orden Izquierdo,E.; Caraba?o Aguado,I.; Pelayo García,F.J.;
Pediatría Atención Primaria , 2011, DOI: 10.4321/S1139-76322011000200010
Abstract: lactose is a widely distributed disaccharide in the diet and pharmaceutical industries. it is the sugar from the milk of mammals. the loss of intestinal lactase activity with age is frequent. it varies between ethnic and genetic conditions, and may cause its malabsorption. it may also be secondary to intestinal mucosal damage and, rarely, to congenital deficiency. malabsorption does not necessarily imply clinical intolerance, with gastrointestinal symptoms after its ingestion. the exclusion of lactose from the diet produces clinical improvement but it could lead to a defect in the recommended daily intake of other nutrients such as calcium. it can be reintroduced into the diet but there is an individual clinical threshold of tolerance.

Abstract: the birth of an infant with ambiguous genitalia represents an emotional shock for the family, a challenge for the medical doctors and a critical situation in neonatal stage. individuals with a congenital discrepancy between external genitalia, gonadal and chromosomal sex, are classified as a disorder of sex development (dsd). in 2006 a new consensus about the terminology was reached, so pejorative terms like intersex, hermaphroditism and pseudohermaphroditism were abandoned. from then on, dsd is used. dsd presents an annual incidence of 1/4500 alive newborn and the adrenal hyperplasia is the most common cause. the incidence is increased if cryptorquidia, microphallus and hypospadias are included. the evaluation of newborns with ambiguous genitalia should be carried out as soon as possible, because the most common cause, congenital adrenal hyperplasia, can be life threatening. the initial assessment should include physical examinations, serum electrolytes, 17-hydroxyprogesterone, cortisol, 11-deoxycortisol, 17-hydroxypregnenolone, dehydroepiandrosterone and adrenocorticotropic hormone in order to evaluate for the possibility of congenital adrenal hyperplasia. furthermore, karyotype, sry gen and abdominal ultrasonography must be requested. these disorders will be classified depending on karyotype as 46xx dsd, 46xy dsd or dsd due to chromosome disorders. the management of this situation must be performed by a multidisciplinary team (neonatologist, genetics, paediatric endocrinologist, paediatric surgeon and psychologist) in hospitals with documented experience.
Crisis de llanto, irritabilidad y masa en el hemiabdomen derecho no siempre son sinónimos de invaginación intestinal

Pediatría Atención Primaria , 2011, DOI: 10.4321/S1139-76322011000600010
Abstract: acute urinary retention in children is seldom described in medical literature. there is no predominance of sex, and their median age is four years. it can be primary (nephrourological diseases) or secondary to different conditions (surgery, immobility, chronic neurological disorders, mental retardation, drugs abuse, anticholinergics, constipation). it can simulate an intussusception, with severe abdominal pain and irritability. the treatment is the evacuation of urine by catheterization. it should be done in stages if the bladder volume is very high, to avoid ex-vacuo hematuria.
Disminución del nivel de conciencia: ?causa abdominal?

Abstract: intussusception is a common cause of acute abdomen and intestinal obstruction in children between 3 months and 6 years old. we describe a case of a 2-year-old child who went to the emergency department for an episode of headache, vomiting and low reactivity to stimuli. after an initial study to rule out potential causes of altered mental status, an abdominal ultrasound gave the diagnosis of ileo-ileal intussusception. the subsequent resolution was spontaneous. abdominal causes should be excluded in the pediatric age in case of changes in level of consciousness that are unexplained by other conditions. abdominal ultrasound is a noninvasive technique that can help the diagnosis.

Nutrición Hospitalaria , 2012, DOI: 10.3305/nh.2012.27.4.5848
Abstract: Introducción: La nutrición oral del prematuro no es posible hasta la adquisición del reflejo de la succión-deglución-respiración. Su retraso prolonga la estancia hospitalaria y aumenta la incidencia de trastornos oro-motores en los primeros a os de la infancia. Objetivos: Analizar la transición de la nutrición enteral a la oral, la comorbilidad asociada con su retraso y el impacto de una estimulación precoz de la succión en una cohorte de prematuros. Pacientes y métodos: Revisión retrospectiva de 95 prematuros menores de 32 semanas de gestación (SG) ingresados en una UCI neonatal en los últimos 4 a os. Se revisó la edad gestacional, somatometría al nacimiento y al alta, comorbilidad asociada, duración de la ventilación mecánica, necesidades de oxígeno, momento de inicio/fin de nutrición enteral/oral, inicio del método canguro y estimulo de la succión y ganancia ponderal media diaria. Resultados: La estimulación de la succión se inició entre la semana 29 y 40 SG (media y mediana 32 SG). La nutrición oral se inició entre la 31-40 SG (media y mediana 33SG) y completó entre la 33-44 SG (media y mediana 35 SG). La nutrición oral se retrasó en los pacientes que necesitaron más tiempo de ventilación mecánica y oxigenoterapia. Hubo una correlación positiva entre el inicio de la estimulación de la succión y el momento de adquisición de una nutrición oral completa (84% test de correlación de Spearman) y el tiempo de estancia hospitalaria (80% test de correlación de Spearman). Conclusiones: El estímulo precoz de la succión en el paciente pretérmino parece facilitar la nutrición oral completa de manera precoz, asociándose a una disminución en la estancia hospitalaria y a una mejora en la ganancia ponderal media diaria. Introduction: Premature baby's oral feeding is not possible until the reflex of sucking-swallowing-breathing adquisition. Its delay extends hospital stay and increases the incidence of oral motor disorders in early childhood. Aims: To analyze the transition from enteral to oral nutrition, the comorbidity associated with its delay and the impact of an early suction stimulation in a cohort of premature babies. Patients and methods: Retrospective checking of 95 infants less than 32 gestation weeks (GW) admitted to a neonatal ICU in the last 4 years. It was revised the gestational age, anthropometric at birth and discharge, comorbidity, duration of mechanical ventilation, oxygen requirements, time of beginning and end of enteral/oral nutrition, beginning of Kangaroo method and the suction stimulation and the daily weight gain average. Results: Suction st

Abstract: introduction: eye infections are frequent in children. the distinction between periorbital and orbital is essential because of its different prognosis. early detection and treatment are im portant because they can produce serious complications. objective: to check the epidemiology, clinical symptoms and prognosis, microbiology, complications and periorbital/orbital cellulitis treatment in children younger than fifteen admitted into hospital due to this pathology. patients and methods: retrospective study of patients under 15 years hospitalized because of periorbital cellulitis from april of 1992 to december of 2006 in getafe university hospital. the clinical criterions followed to diagnose periorbital cellulitis were the presence of inflammatory signs in eye or periorbital soft tissues; including at least palpebral swelling and conjunctival injection. signs like the disminution of visual acutennes, the alteration of the eye motility, chemosis, proptosis, alterations of the fundus examination and systemic symptoms orientated to orbital cellulitis. in doubtful cases, the location diagnosis was established by tac. results: sixty six patients were included and thirty six (55%) were males. the median of the age was 38 months (rank: 3 months-14 years). the associated pathology was: conjunctivitis 26%, upper respiratory tract infections 42%, dental pathology 6%, local cutaneous trauma 12% and others 14%. associated sinusitis was present in 19 of the 27 patients who underwent image technique. the more frequent pathogens considered were staphylococcus aureus and streptococcus pneumoniae, and with less frequency haemophilus influenzae. all the patients received an intravenous antibiotic treatment: 36% with a single antibiotic (cefuroxime or amoxicillin-clavulanic acid) and 64% multiple antibiotic therapy, associating systemic corticosteroids in the 24% and local surgical treatment in the 7.5%. all the patients improved and they had not sequelae. conclusions: the periorbital/o
Placing Place: Speech in José María Arguedas’ The Foxes  [PDF]
Lucas Izquierdo
Advances in Literary Study (ALS) , 2013, DOI: 10.4236/als.2013.14011

Critical approximations carried out from the global south entail spatial and epistemological challenges to the hegemony of western modernity. This article argues that José María Arguedas’ The Fox from Up Above and the Fox from Down Below(1971) produces a language that embodies and transforms an Aris-totelian conception of speech. Written in an avant-garde vernacular, the novelcongeals a multiplicity of worldviews, utopias, and mercantile discourses that converge in Chimbote-Peru. Guided by Jacques Ran-ciere’s Disagreement(1998) and Dissensus(2010), the analysis is divided in two stages. The first stage examines the notion of speech and a constitutive wrong that establishes a community. The second stage addresses the symbiotic relationship of speech, its place of enunciation, and the conception of an alternate social order. The analysis places Arguedas incritical dialogue with Aristotelian speech, Ranciere’s notion of wrong, and the emergence or failure of claiming speech in canonical history.

Conserved electromagnetic currents in a relativistic optical model
J. W. Van~Orden
Physics , 2006, DOI: 10.1103/PhysRevC.74.034607
Abstract: A simple model of a relativistic optical model is constructed by reducing the three-body Bethe-Salpeter equation to an effective two-body optical model. A corresponding effective current is derived for use with the optical-model wave functions. It is shown that this current satisfies a Ward-Takahashi identity involving the optical potential which results in conserved current matrix elements.
