Frecuencia de la deficiencia mental en la provincia de Teruel (1981-82).

Estudiar los diferentes aspectos en la deficiencia mental, en este caso en la provincia de Teruel, consultando organismos púbicos, observando los tratamientos y distribución de datos estadísticos y estudiando la población en centros de Educación Especial, agrupados en grados, sexos, edad y medio. Se exponen las nociones básicas sobre la deficiencia mental, clasificaciones, características de estos sujetos, frecuencia y deficiencia. El trabajo se divide en seis capítulos: el primer capítulo muestra el concepto de deficiente mental, las dificultades en cuanto a su definición, los diferentes criterios y métodos para definir, y los factores característicos de la deficiencia mental. En el capítulo segundo se describe la clasificación de la deficiencia mental, según la clasificación de Binet-Simon, según Terman, según la Organización mundial de la salud (O.M.S.) y según Lang. En el capítulo tercero se exponen las características propias de la deficiencia, según los grados propuestos por la O.M.S, y una clasificación por posibilidades educativas. En el capítulo cuarto se desarrolla la etiología del trastorno, los trastornos genéticos, factores prenatales, natales y postnatales y los factores socioeconómicos. En el capítulo quinto se trata la frecuencia de la deficiencia mental en España, las dificultades encontradas y diferentes estudios realizados por el Instituto de Sociología aplicada en Madrid, junto con el estudio del Instituto de Ciencias del hombre. En el capítulo sexto se explica la frecuencia de la deficiencia mental en la provincia de Teruel de determinadas zonas en la provincia, determinación teórica de la frecuencia, los deficientes registrados, escolarizados y diferentes consideraciones globales. 1) Existen gran número de personas con deficiencia que no están inscritas en ninguna institución. 2) La mayor frecuencia se da en zonas mineras dentro de la zona estudiada. 3) La mayoria de los deficientes mentales estudiados estarían escolarizados en centros Nacionales, es de sospechar que en aulas de Educación Especial. 4) Sería necesario dotar al menos a las zonas con mayores frecuencias, no sólo en la capital, de gabinetes con personal cualificado. 5) La adecuada inserción de los deficientes en la vida común no se soluciona con la creación de puestos educativos, residencias, talleres, etc..

The ν2, 2ν2, 3ν2, ν4 and ν2+ν4 bands of 15NH3

The ir absorption of gaseous 15NH3 between 510 and 3040 cm−1 was recorded with a resolution of 0.06 cm−1. The ν2, 2ν2, 3ν2, ν4, and ν2 + ν4 bands were measured and analyzed on the basis of the vibration-rotation Hamiltonian developed by V. Špirko, J. M. R. Stone, and D. Papoušek (J. Mol. Spectrosc. 60, 159–178 (1976)). A set of effective molecular parameters for the ν2 = 1, 2, 3 states was derived, which reproduced the transition frequencies within the accuracy of the experimental measurements. For ν4 and ν2 + ν4 bands the standard deviation of the calculated spectrum is about four times larger than the measurements accuracy: a similar result was found for ν4 in 14NH3 by Š. Urban et al. (J. Mol. Spectrosc. 79, 455–495 (1980)). This result suggests that the present treatment takes into account only the most significant part of the rovibration interaction in the doubly degenerate vibrational states of ammonia.

Short Communication: effects of 2-hydroxy-4-(methylthio) butanoic acid isopropyl ester on milk production and composition of lactating Holstein dairy cows

Sixteen multiparous Holstein cows were used to determine the effects of 2-hydroxy-4-(methylthio) butanoic acid isopropyl ester (HMBi: 0 vs. 1.26 g/kg of total ration dry matter (DM) and dietary crude protein (CP) concentration [14.7% (low) vs. 16.9% (standard), DM basis] on milk yield and composition using a replicated 4 x 4 Latin square design experiment with 4-wk periods. Cows were fed ad libitum a total mixed ration with a 1: 1 forage-to-concentrate ratio (DM basis), and diets provided an estimated 6.71 and 1.86% lysine and methionine, respectively, in metabolizable protein for the low-protein diet and 6.74 and 1.82% in the standard protein diet. Dry matter intake, milk yield, and composition were measured during wk 4 of each period. There were no effects on DM intake, which averaged 24.7 kg/d. There was an interaction between dietary CP and HMBi for milk yield and 3.5% fat-corrected milk (FCM). Feeding HMBi decreased milk and FCM yield when fed with the low-CP diet but did not affect milk or FCM yield when fed with the standard CP diet. Feeding HMBi increased milk protein concentration regardless of diet CP concentration and increased milk protein yield when added to the standard CP diet but not the low-CP diet. The positive effect of HMBi on milk protein yield was only observed at the standard level of dietary CP, suggesting other factors limited the response to HMBi when dietary protein supply was restricted.

Clinical and pathological assessment of 82 patients with cardiovascular diseases undergoing autopsy at the Hospital das Clínicas of the Faculdade de Medicina de Botucatu from 1988 to 1993

OBJECTIVE: To evaluated the clinical diagnostic, efficiency for basic death causes in patients dying of circulatory disease and de relative frequency of those diseases. METHODS: Analysis of medical record data of 82 patients, ages from 16 to 84 years old (68 over 40 years old), whose died of circulatory disease and had undergone necropsy in the period from 1988 to 1993 years in the University Hospital of Medicine Faculty of Botucatu-UNESP, Br. RESULTS: The functional class of patients were III or IV, in 78%, and 81.7% needed urgent hospitalization. By the clinical judgment the death were by ischemic heart disease in 32 (21 acute myocardial infarction), Chagas'disease in 12, valvopathy in 11, cardiomyopathy in 7, heart failure with no specification of cardiopathy in 11 and other causes in 9. At the necropsy the death cause was ischemic heart disease in 34 patients, valvopathy in 10, Chagas'disease in 10, cardiomyopathy in 5, and heart failure with no specification of cardiopathy in 2.The concordance taxes were in thhe same order: 94,6%, 90,0%, 83.3%, 71.4% and 28.5%. CONCLUSION: There was a great efficiency of clinical diagnosis for death cause in a general university hospital. The ischemic heart disease were the main causes of death.

Effect of an experimental 4% titanium tetrafluoride varnish on dental erosion by a soft drink

Objectives: This in vitro study assessed the effect of an experimental 4%TiF4 varnish on enamel erosion.Methods: Sixty bovine enamel blocks were randomly allocated to each type of varnish:Duraphat((R)) -D (NaF, 2.26%F), Duofluorid((R))-F(NaF, 2.71% F), TiF4-T(2.45%F) and no-fluoride-P. After application of the varnishes, the blocks were subjected to six sequential pH cycles (cola drink for 10 min and artificial saliva for 50 min, each) per day, during 4 days. After the pH cycles, the blocks were maintained in artificial saliva for 18 h. Enamel alterations were determined in the 2nd and 4th days, using profilometry (wear) and microhardness (%SMHC) tests. Data were tested using ANOVA and Tukey's tests (p < 0.05).Results: the mean %SMHC (+/- S.D.) at the 2nd and 4th day was, respectively, D (-77.26 +/- 5.04(a) and -88.59 +/- 5.11(A)), F (-76.79 +/- 7.82(a) and -88.78 +/- 6.10(A)), T(-88.28 +/- 3.19(b) and -92.04 +/- 2.54(A,B)) and P (-87.96 +/- 2.23(b) and -94.15 +/- 1.14(B)). The mean wear (mu m +/- S.D.) at the 2nd and 4th day was, respectively, D (3.16 +/- 0.32(a) and 7.56 +/- 0.90(A)), F(3.35 +/- 0.78(a,b) and 7.92 +/- 0.98(A)), T (3.81 +/- 0.43(b) and 7.69 +/- 0.76(A)) and P (3.43 +/- 1.13(a,b) and 7.31 +/- 0.53(A)).Conclusions: the NaF varnishes reduced the softening, but had no effect on the reduction of the wear. The TiF4 varnish was not able to reduce the softening and wear. (C) 2007 Elsevier Ltd. All rights reserved.

Carcinoma basaloide - Escamoseo de cebeça: relato de 4 casos

Basaloid squamous carcinoma is an aggressive subtype of squamous carcinoma of superior aerodigestive tract. This tumor has been recently described and it seems to have higher incidence in tongue, hypopharynx and supraglottis. It has more agressive biological behavior than pure type of squamous cell carcinoma. We report 4 cases of this tumor and we present a review of the literature.

Comparação entre o sistema Autoścan-4 e métodos convencionais na identificação de bacilos Gram-negativos não fermentadores, isolados de materiais clínicos de pacientes em Presidente Prudente - SP

Ninety eight strains of glucose-nonfermenting Gram-negative bacilli were analyzed and isolated from several clinical materials of 95 patients admitted at the Dr. Domingos Leonardo Cerávolo University Hospital and three from outpatients. All of them were assisted in the Laboratory of Clinical Analysis of Unoeste University, Presidente Prudente, SP, from the period of October of 1999 to April of 2001. In this work, the level of agreement between the semi-automated commercial system AutoScan-4 and the conventional system for the identification of those bacteria were studied comparatively. There was agreement in 81 (82.7%), showing that both methodologies are useful for identification; partial agreement in six strains (6.1%) and disagreement in 11 (11.2%). The comercial system did not identify nine (9.2%) of the strains and reported them as very rare biotypes.

Interaction of the meso-tetrakis (4-N-methylpyridyl) porphyrin with gel and liquid state phospholipid vesicles

The interaction of the cationic meso-tetrakis 4-N-methylpyridyl porphyrin (TMPyP) with large unilamellar vesicles (LUVs) was investigated in the present study. LUVs were formed by mixtures of the zwitterionic 1,2-dipalmitoyl-sn-glycero-phosphatidylcholine (DPPC) and anionic 1,2-dipalmitoyl-sn-glycero-3-phosphoglycerol (DPPG) phospholipids, at different DPPG molar percentages. All investigations were carried out above (50 degrees C) and below (25 degrees C) the main phase transition temperature of the LUVs (similar to 41 degrees C). The binding constant values, K-b, estimated from the time-resolved fluorescence study, showed a significant increase of the porphyrin affinity at higher mol% DPPG. This affinity is markedly increased when the LUVs are in the liquid crystalline state. For both situations, the increase of the K-b value was also followed by a higher porphyrin fraction bound to the LUVs. The displacement of the vesicle-bound porphyrins toward the aqueous medium, upon titration with the salt potassium chloride (KCl), was also studied. Altogether, our steady-state and frequency-domain fluorescence quenching data results indicate that the TMPyP is preferentially located at the LUVs Stern layer. This is supported by the zeta potential studies, where a partial neutralization of the LUVs surface charge, upon porphyrin titration, was observed. Dynamic light scattering (DLS) results showed that, for some phospholipid systems, this partial neutralization leads to the LUVs flocculation. (C) 2012 Elsevier Inc. All rights reserved.

Infecções de corrente sanguínea por bactérias multirresistentes em UTI de tratamento de queimados: experiência de 4 anos

INTRODUÇÃO: O conhecimento do perfil de resistência aos antibióticos das bactérias de um nosocômio é essencial para orientar tratamento adequado dos pacientes. Isso é especialmente importante para os pacientes mais graves, já que o tratamento deve ser instituído antes do resultado das culturas. O objetivo deste estudo foi analisar o perfil das bactérias multirresistentes encontradas nas hemoculturas de pacientes admitidos na Unidade de Tratamento Intensivo (UTI) da Unidade de Queimados do Hospital das Clínicas da Faculdade de Medicina da Universidade de São Paulo. MÉTODO: Foram analisados 178 pacientes internados na UTI para tratamento de queimados, no período de 2009 a 2011, sendo 131 do sexo masculino, com média de idade de 29,2 anos. RESULTADOS: Entre os pacientes analisados, 80 (44,9%) apresentaram hemocultura periférica positiva, sendo 66 (82,5%) casos com bactérias multirresistentes. Em 48 pacientes, foram isoladas Staphylococcus sp., que se apresentaram resistentes à oxacilina em 33 deles. Em 11 pacientes, foram isoladas Acinetobacter baumanii, que se apresentaram resistentes a imipenem em 8 casos. Em 19 pacientes, foram isoladas Pseudomonas sp., resistentes a imipenem em 16 casos. Em 10 pacientes foram isoladas Enterobacter sp., resistentes a amicacina e ciprofloxacina em 2 casos. A presença de bactérias multirresistentes não foi associada a maior ocorrência de óbitos, porém foi verificado maior tempo de internação (52,6 dias vs. 36,3 dias para os grupos com e sem bactérias multirresistentes, respectivamente; P = 0,0306). Não foi encontrada interação significante entre superfície corpórea queimada e presença de bactérias MR. CONCLUSÕES: A presença de bactérias multirresistentes é um problema grave, tanto pela prevalência como pela morbidade e mortalidade associadas.
