ABSTRACT

Resumen Introducción: la alergia a la proteína de leche de vaca (APLV) es la alergia alimentaria más frecuente en el primer año de vida. La evidencia actual acerca de la respuesta a una fórmula extensamente hidrolizada (FEH) a base de suero es insuficiente. Objetivo: determinar los desenlaces clínicos en lactantes con APLV a una FEH a base de suero (Nutrilón Pepti Junior®). Metodología: estudio retrospectivo, tipo serie de casos. Se incluyeron lactantes (≤12 meses) con APLV valorados en la consulta externa entre enero de 2011 y octubre de 2015 en un servicio de gastroenterología pediátrica. La información de datos demográficos, manifestaciones digestivas, tiempo de inicio de síntomas, antropometría y respuesta clínica a la fórmula fue abstraída a partir de la revisión de la historia clínica. Se comparó el estado nutricional de los pacientes en la primera y en la consulta de control un año después utilizando la prueba t de Student. Resultados: se incluyeron 40 lactantes (42,5% varones) de 3,3 ± 2,4 meses, con síntomas como vómito/regurgitación, cólico/irritabilidad y deposición con sangre. Los antecedentes familiares y perinatales relacionados con el desarrollo de APLV fueron la ingesta de biberón en la primera semana de vida: 27 (67,5%), madre ≥30 años: 33 (82,5%), atopia en 2 familiares: 12 (30%) y parto por cesárea: 30 (75%). 37 (92,5%) pacientes mostraron una respuesta positiva a una FEH a base de suero, mientras que 3 (7,5%) pacientes no respondieron y requirieron una fórmula a base de aminoácidos (FAA) libres. Los z-score de peso/edad: -0,69 ± 1,03 y peso/talla: -0,79 ± 1,00 de la primera consulta mejoraron en el seguimiento posterior al año (p <0,05): peso/edad: -0,27 ± 0,98 y peso/talla: -0,14 ± 0,98. Conclusión: se encontró recuperación nutricional y tolerancia a la leche de vaca en un alto porcentaje de lactantes con APLV que recibieron una FEH a base de suero.


Abstract Introduction: Cow's milk protein allergies (CMPA) are the most frequent food allergies in the first year of life. Current evidence about responses to an extensively hydrolyzed serum based formula is insufficient. Objective: This study's objective was to determine clinical outcomes in infants with CMPA to an extensively hydrolyzed serum based formula (Nutrilón Pepti Junior®). Methodology: This is a retrospective case series study of infants 12 months old or younger diagnosed with CMPA in the outpatient clinic of a pediatric gastroenterology service between January 2011 and October 2015. Information including demographic data, digestive manifestations, time of onset of symptoms, anthropometry and clinical responses to formula was abstracted from a review of clinical histories. Patients' nutritional statuses at first and one year follow-up consultations were compared using Student's t-test. Results: Forty infants (42.5% males) whose average age was 3.3 ± 2.4 months were included. Their symptoms included vomiting/regurgitation, colic/irritability and bloody stools. Family and perinatal history related to the development of CMPA included bottle feeding in the first week of life (27 patients, 67.5%), mothers who were thirty years of age or older (33 patients, 82.5%), atopy in two family members (12 patients, 30 %) and cesarean deliveries (30 patients, 75%). Thirty-seven patients (92.5%) responded positively to an extensively hydrolyzed serum based formula while three patients (7.5%) did not respond and required a milk-free amino acid based formula. The first consultation z-score of P/E was -0.69 ± 1.03 while the first consultation z-score of P/T was -0.79 ± 1.00. These improved at the one year follow-up to (p <0.05) P/E: -0.27 ± 0.98 and P/T: -0.14 ± 0.98, respectively. Conclusion: Nutritional recovery and tolerance to cow's milk was found in a high percentage of infants with CMPA who received an extensively hydrolyzed serum based formula.

ABSTRACT

Resumen: La falla en la regeneración de las neuronas del sistema nervioso central (SNC) en vertebrados superiores es un problema que no se ha resuelto completamente, esto limita la rehabilitación de muchas conductas motoras después de una lesión en la médula espinal. En la regeneración neuronal intervienen múltiples factores y de estos, los que inducen el crecimiento neurítico se han estudiado para intentar favorecer la extensión y la reconexión de las neuronas lesionadas con sus blancos. La regeneración del SNC de sanguijuelas se ha estudiado intensamente porque permite abordar el problema a diferentes niveles con distintas técnicas, en este trabajo se obtuvo el espectro de absorción óptico, con espectroscopía fotoacústica (EFA), del SNC y de tejido de la sanguijuela Haementeria officinalis, con el objetivo de conocer las longitudes de onda óptimas para la irradiación posterior de células del SNC y de tejido H. officinalis. Los resultados de este estudio muestran que el SNC de estos organismos absorbe en la region comprendida de 300 nm a 500 nm, y las muestras de tejido tienen un máximo de absorción óptico proximo a 300 nm, además se observaron diferencias evidentes entre los espectros de absorción ópticos del SNC con lesión y el control (sin lesión).


Abstract: The failure in the neuron regeneration in the central nervous system (CNS) in higher vertebrates, is a not completely solved problem, this limits the rehabilitation of many motor conducts after an injury in the spinal cord. In neuronal regeneration multiple factors are involved, between them those that induce the neurite outgrowth which has been studied to try to encourage the extension and reconnection of the injury neurons with their blanks. The regeneration of the CNS of leeches has been intensely studied because allows to approach the problem at different levels with different techniques. In this study the optical absorption spectrum of the CNS and the tissue of the leech H. officinalis was obtained, by using photoacoustic spectroscopy (PAS), in order to investigate the optimal wavelenghts for later irradiation of CNS cells and tissue of H. officinalis. The results of this study show that the CNS of these organisms absorbs in the region of 300 nm to 500 nm, and the tissue samples has a maximun of optical absorption near to 300 nm, besides were observed evident differences between the optical absorption spectra of CNS with injury and the control (without injury).

ABSTRACT

Background: It is still debated which is the best treatment for Basedow-Graves' hyperthyroidism (BGH). We reviewed 195 patients treated and followed-up during the past 30 years: 88 treated with propylthiouracil (PTU), 70 with 131I and 37 thyroidectomized Aim: to analyze the efficacy of each therapy in terms of achieving euthyroidism and the search of possible indexes for success. Surgery attained euthyroidism in 70.2 percent but has disadvantages; 131I accounted for the highest hypothyroid rate (72.1percent) irrespective of the dose administered; PTU alone was successful in only 26.4 percent but combined with T4, success rose to 62.5 percent (p < 0.025). Suppression test and/or TRAb measurements after 6 mo PTU therapy were used to decide if therapy continued or was changed to other form of treatment. Using this criteria, 87.5 percent of pts with positive results achieved longstanding euthyroidism. Pretreatment predictive indexes were goiter size, T4 levels and 24 h/RAI uptake. Conclusions: As 131I induces hypothyroidism in over 2/3 of pts and surgery besides its cost is not devoid of serious complications, we advocate for the use of PTU as first line therapy; combined treatment (PTU + T4) seems promising. If after 6 mo on PTU, TRAb or Suppression test do not improve, we recommend 131I or surgery

ABSTRACT

El tronco posterior del nervio mandibular es en su mayor parte sensitivo, aunque recibe algunos filetes de la raíz motora. Se divide en nervios auriculotemporal, lingual y alveolar (dentario) inferior. El nervio auriculotemporal surge generalmente por dos raíces que rodean la arteria meníngea media, corre hacia atrás bajo el pterigoideo externo sobre la superficie del periestafilino externo y pasa entre el ligamento esfenomaxilar y el cuello de la mandíbula. Pasa luego lateralmente por detrás de la articulación temporomandibular en relación con la porción superior de la glándula parótida. Finalmente, emergiendo por detrás de la articulación, asciende posterior a los vasos temporales superficiales, y por encima del arco cigomático, dando los ramos temporales superficiales.

ABSTRACT

El ganglio pterigopalatino (esfenopalatino), es el mayor de los ganglios periféricos del sistema parasimpático. Se sitúa profundamente en la fosa pterigopalatina, junto al forámen esfenopalatino y por delante del conducto vidiano. Es ligeramente aplanado, de aspecto rojo grisáceo, y se localiza inmediatamente por debajo del nervio maxilar, donde éste cruza la fosa. Aun cuando está conectado funcionalmente con el nervio facial (VII par). Topográficamente establece relaciones íntimas con el nervio maxilar y sus ramos. La raíz motora o parasimpática la forma el nervio vidiano, que penetra posteriormente en el ganglio. Se cree que sus fibras proceden de un núcleo lagrimal especial, en la porción inferior de la protuberancia, y corren por la raiz sensitiva del facial (nervio intermediario de Wrisberg), y su ramo petroso superficial mayor antes de que éste se una con el petroso profundo para formar el nervio vidiano. Estas fibras preganglionares hacen escala en el ganglio y las fibras postganglionares siguen un curso complicado hasta alcanzar su destino. Dejando el ganglio por uno de los ramos ganglionares, se anastomosan con el maxilar y pasan a su ramo orbitario. Desde aquí siguen generalmente por el nervio cigomaticotemporal y posteriormente parten por el anastomótico, por el que se conectan con el nervio lagrimal. Alcanzan así la glándula lagrimal, inervándola con fibras secretomotoras. Además, a las glándulas paltinas, faríngeas y nasales llegan fibras secretomotoras, de origen dudoso. Se cree que siguen una vía similar hasta su llegada al ganglio, donde hacen escala. Sus fibras posganglionares corren por los ramos palatinos y nasales del ganglio.

ABSTRACT

Annual surveillance studies were initiated in 1985 to determine the incidence and prevalence of HIV-1 infection in female prostitutes registered through the Social Hygiene Clinic System of the Philippine Department of Health. All of the confirmed HIV-1 seropositive women detected in the above surveys who could be contacted were followed up about every three months to monitor their clinical and immunological status. Since we regularly interviewed and examined these HIV-1 seropositive women, we were able to note the occurrence of pregnancies following HIV diagnosis. By September 1990, 54 HIV-1 seropositive women (aged 18-35) detected from the above surveys had been interviewed and examined. Twenty-six of these HIV-1 positive women had a total of 37 pregnancies. Eight were pregnant at the time of HIV diagnosis: three term deliveries, one premature delivery (PD) at eight months, three abortions, and one lost to follow-up while still pregnant. Five of these eight had repeat pregnancies: two term deliveries, two abortions, and one lost to follow-up while pregnant. Eighteen other women became pregnant one or more times after HIV diagnosis: seven term deliveries, 13 abortions, two PDs, one ectopic pregnancy terminated, one currently pregnant, and one lost to follow-up during pregnancy. There was no clear indication from clinical examinations and CD4+ cell counts that pregnancy exacerbated the course of HIV-1 related disease in these women. One of the 12 term infants has died and eight have developed non-specific findings that are suggestive but not diagnostic of HIV infection.2+ strongly seropositive by both ELISA and Western blot assay at 16 months.

ABSTRACT

El nervio trigénimo o V par craneal se considera el primer arco branquial; la mayor parte de sus fibras motoras inervan los músculos de la masticación, derivados del proceso mandibular y maxilar, clasificadas como fibras Viscerales Eferentes Especiales (EVE). Las fibras sensoriales, originadas en las neuronas del ganglio trigeminal, son aferentes sensitivas que se distribuyen en el integumento (piel) de la cara y el cráneo; el nervio tiene además fibras eferentes viscerales y fibras propioceptivas aferentes somáticas (AF), para la articulación temporo-mandibular y los alvéolos dentarios (periodonto).

ABSTRACT

A study of female prostitutes in Manila who tested positive for human immunodeficiency virus (HIV) antibody ascertained demographic and sexual behavior information following diagnosis. Counselling alone did not appear to have a major impact on the sexual behavior of the HIV positive women since most continued to work as prostitutes. Switching from high risk to low risk jobs in bars is not effective in preventing HIV positive women from engaging in prostitution. Revoking work permits is only effective if enforced with adequate follow up. Alternative job training programs may offer a viable approach.
