RESUMO Hemorragia subaracnóidea (HSA) proporciona alterações nas altas funções cerebrais. Contudo, há poucos trabalhos enfatizando as alterações da linguagem na HSA aneurismática e a influência da localização do aneurisma. Objetivos Analisar e comparar os desempenhos da linguagem e fluência verbal na HSA nos períodos pré e pós-cirúrgicos nos pacientes com aneurismas da comunicante anterior (AcomA), cerebral média (ACME) e comunicante posterior esquerdas (AcomPE). Métodos A avaliação da linguagem de 79 pacientes com HSA aneurismática foi realizada em duas ocasiões: pré e pós cirurgia. Eles foram divididos em três grupos de acordo com a localização do aneurisma. Resultados Os grupos apresentaram deterioração na avaliação pós-operatória com diferentes características. O grupo da ACME demonstraram deterioração na fluência e nomeação, enquanto o da AcomPE pioraram nos testes de linguagem escrita e fluência. Conclusões Após o tratamento cirúrgico, os pacientes deterioraram em vários itens de linguagem com diferenças relacionadas à localização do aneurisma.

ABSTRACT Sub-arachnoid hemorrhage (SAH) promotes impairment of upper cortical functions. However, few information is available emphasizing changes in language after aneurismal SAH and aneurysm location influence. Objective To assess the language and verbal fluency performance in aneurismal SAH pre- and post-surgery in patients caused by an aneurysm of the anterior communicating artery (AcomA), left middle cerebral artery (L-MCA) and left posterior comunicating artery (L-PcomA). Methods Assessment in 79 patients with SAH, on two occasions: pre- and post surgical treatment. They were divided into three groups by the aneurysms’ location. Results Deterioration is detected in the performance of all patients during the post-surgical period; L-MCA aneurysm patients displayed a reduction in verbal naming and fluency; L-PcomA patients deteriorated in the written language and fluency tasks. Conclusion After the surgical procedure the patients decreased in various language tasks and these differences in performance being directly related to the location of the aneurysm.

Mucopolysaccharidosis type I (MPS I) is a rare lysosomal disorder caused by deficiency of alph-L-iduronidase. Few clinical trials have assessed the effect of enzyme replacement therapy (ERT) for this condition. We conducted an exploratory, open-label, non-randomized, multicenter cohort study of patients with MPS I. Data were collected from questionnaires completed by attending physicians at the time of diagnosis (T1; n = 34) and at a median time of 2.5 years later (T2; n = 24/34). The 24 patients for whom data were available at T2 were allocated into groups: A, no ERT (9 patients; median age at T1 = 36 months; 6 with severe phenotype); B, on ERT (15 patients; median age at T1 = 33 months; 4 with severe phenotype). For all variables in which there was no between-group difference at baseline, a delta of ;±20% was considered clinically relevant. The following clinically relevant differences were identified in group B in T2: lower rates of mortality and reported hospitalization for respiratory infection; lower frequency of hepatosplenomegaly; increased reported rates of obstructive sleep apnea syndrome and hearing loss; and stabilization of gibbus deformity. These changes could be due to the effect of ERT or of other therapies which have also been found more frequently in group B. Our findings suggest MPS I patients on ERT also receive a better overall care. ERT may have a positive effect on respiratory morbidity and overall mortality in patients with MPS I. Additional studies focusing on these outcomes and on other therapies should be performed.

Relatamos a transformação de uma dilatação infundibular da origem da artéria comunicante posterior em aneurisma, após onze meses do diagnóstico angiográfico e cirúrgico. Apenas onze casos semelhantes foram descritos na literatura internacional. Relatos como esse trazem à tona os problemas diagnósticos e terapêuticos representados por essas lesões e suscitam a necessidade do melhor entendimento das dilatações infundibulares encontradas nas artérias cerebrais.

In this case an aneurysm of the right posterior communicating artery developed 11 months after an infundibular dilation of this artery had been angiographycally and surgically demonstrated. In the best of the authors' knowledge, there are only eleven such cases reported in the literature. This report brings about diagnostic and therapeutic questions regarding arterial infundibula and the need of a better understanding of those lesions.

La composición química aproximada y la energía de las especies acompañantes del camarón utilizadas para consumo humano y animal se estudió en Alvarado, Vereacruz (Golfo de México). Cinco muestreos se realizaron entre septiembre de 1994 y marzo de 1995 en barcos camaroneros. Las muestras se congelaron a bordo para los análisis de laboratorio de la porción comestible. Los resultados indicaron 16 familias, 22 especies de peces y 1 molusco (calamar). Después de la humedad, la fracción química más abundante fue la proteína cruda con valores entre 14.3 y 19.6%. Los hidratos de carbono fueron desde 2.1 a 7.4%. El extracto etéreo (lípidos) fue menos abundante pero variable numéricamente (0.5 a 3.8%), las cenizas se cuantificaron entre 0.10 y 0.24%. La energía presentó la menor variación numérica (4.5 a 5.2 kcal/g). 12 especies son empleadas como alimento animal y solo Pristipomoides aquilonaris se reportó como de uso exclusivo para este propósito; la composición química fue similar a la de las especies de consumo humano. Anchoa hepsetus, Synodus foetens, Cynoscion arenarius, Upeneus parvus y Trichiurus lepturus, se recomiendan para alimentación humana, especialmento por su bajo costo en la costa del Golfo de México.

Chemical composition and energy content of the shrimp by-catch used for human and livestock consumption were studied in Alvarado, Veracruz (Gulf of Mexico). Five on-board samplings were done between September 1994 and March 1995 on shrimp ships off Veracruz. The samples were frozen on board for laboratory analysis of the edible portion, they included 16 families and 22 species of fishes and 1 mollusc (squid). After moisture, the crude protein was the most abundant chemical fraction (14.3 and 19.6%); carbohydrates were numerically variable in all groups (2.1 to 7.4%); ether extract (lipids) was less abundant but variable (0.5 to 3.8%), ashes were 0.10 to 0.24%. Crude energy was less variable numerically (4.5 to 5.2 kcal/g); 12 species are used as animal feed and only Pristipomoides aquilonaris was reported as exclusively used for this purpose: chemical composition was similar in species used for human and for livestock consumption; Anchoa hepsetus, Synodus foetens, Cynoscion arenarius, Upeneus parvus and Trichiurus lepturus are recomended for human consumption, specially for low economic level areas of Gulf of Mexico.
