ABSTRACT
Neurological diseases are common in inflammatory bowel disease (IBD) patients, but their exact prevalence is unknown. Method We prospectively evaluated the presence of neurological disorders in 121 patients with IBD [51 with Crohn's disease (CD) and 70 with ulcerative colitis (UC)] and 50 controls (gastritis and dyspepsia) over 3 years. Results Our standard neurological evaluation (that included electrodiagnostic testing) revealed that CD patients were 7.4 times more likely to develop large-fiber neuropathy than controls (p = 0.045), 7.1 times more likely to develop any type of neuromuscular condition (p = 0.001) and 5.1 times more likely to develop autonomic complaints (p = 0.027). UC patients were 5 times more likely to develop large-fiber neuropathy (p = 0.027) and 3.1 times more likely to develop any type of neuromuscular condition (p = 0.015). Conclusion In summary, this is the first study to prospectively establish that both CD and UC patients are more prone to neuromuscular diseases than patients with gastritis and dyspepsia. .
Doenças neurológicas são comuns em pacientes com doença inflamatória intestinal (DII), mas sua prevalência exata é desconhecida. Métodos Nós estudamos prospectivamente a presença de distúrbios neurológicos em 121 pacientes com DII [51 com doença de Crohn (DC) e 70 com colite ulcerativa (RCU)] e 50 controles (gastrite e dispepsia) ao longo de 3 anos. Resultados A avaliação neurológica padronizada (que incluiu testes eletrodiagnósticos) demonstrou que pacientes com DC foram 7,4 vezes mais propensos a desenvolver neuropatias de fibras grossas do que os controles (p = 0,045), 7,1 vezes mais propensos a desenvolver qualquer tipo de condição neuromuscular (p = 0,001) e 5,1 vezes mais propensos a desenvolver queixas autonômicas (p = 0,027). Pacientes com RCU foram 5 vezes mais propensos de desenvolver neuropatia de fibras grossas (p = 0,027) e 3,1 vezes mais propensos a desenvolver qualquer tipo de condição neuromuscular (p = 0,015). Conclusão Em resumo, este é o primeiro estudo prospectivo a estabelecer que os pacientes tanto com DC quanto de RCU são mais propensos a doenças neuromusculares do que os pacientes com gastrite e dispepsia. .

Arterial variations of the femoral triangle are rarely reported in the literature. In the present article, we have reported a case of high origin of the deep femoral artery, which was originating just lower to the inguinal ligament. It was also observed that the lateral circumflex femoral artery arose directly from the femoral artery instead from the deep femoral artery. We have discussed the anatomy, embryological basis, and clinical implications of these variations along with relevant literature review. The importance of knowledge about these variations in therapeutic and diagnostic interventions is discussed.
Variações arteriais no triângulo femoral têm sido pouco relatadas na literatura. No presente artigo, relatou-se um caso de origem alta da artéria femoral profunda, que estava se originando pouco abaixo do ligamento inguinal. Também foi observado que a artéria femoral circunflexa originava-se diretamente da artéria femoral, ao invés de ser originada da artéria femoral profunda. Discutiu-se sobre anatomia, base embriológica e implicações clínicas dessas variações junto com uma revisão da literatura pertinente. A importância do conhecimento sobre essas variações no quadro das intervenções diagnósticas e terapêuticas é discutida.

The purpose of this study was to determine if mild hypoxia alters the responsiveness to vasoactive agents in the renal and the femoral arteries in the fetal sheep. Ten pregnant sheep were operated under halothane anesthesia at 116 to 124 days' gestation. A maternal tracheal catheter was placed for infusing compressed air (control group, n=5) or nitrogen (hypoxia group, n=5) starting on post operative day 6 and maintained for 5 days. Femoral and renal arteries were harvested from the fetus to study the constriction response to phenylephrine (PE 10(-9) to 10(-5) mol/L). To determine the involvement of nitric oxide as a modulator of vessel constriction, N-nitro-Larginine methyl ester (L-NAME) was used at a concentration of 10(-4) mol/L in parallel chambers. In the hypoxia group, maternal Pao2 significantly decreased from a base-line of 110.4 +/-1.4 to 80.5 +/-1.6 (mmHg, p <0.01), fetal Pao2 significantly decreased from a baseline of 20.9 +/-0.3 to 15.5 +/-0.1 (mmHg, p <0.01). Hypoxia was associated with a significant increase in PE maximal response in the absence (184.5 +/-6.6 vs. 146.2 +/-4.3) and presence (166.9 +/-6.3 vs. 145.0 +/-4.5) of L-NAME, and a decrease in EC50 in the absence (6.0 +/-1.1 vs. 27.0 +/-4.1) of L-NAME of femoral arteries. However, there were no significant differences in PE maximal response and EC50 in the absence and presence of L-NAME of renal arteries. We concluded that mild chronic hypoxia seems to increase the fetal femoral artery response to PE, but not in the fetal renal artery. This observation is consistent with a redistribution of cardiac output away from the carcass.
