RESUMO
BACKGROUND: HbA1c variability has been linked to retinopathy, renal disease and autonomic neuropathy in patients with type 1 diabetes mellitus (T1D) and type 2 diabetes mellitus (T2D). Although the same relationship has been demonstrated for diabetic peripheral neuropathy (DPN) in patients with T2D, data for T1D are still lacking. METHODS: Patients older than 17 years of age with ≥ 10 years of T1D duration and follow-up were included. All patients underwent nerve conduction studies and neurological examination. Laboratorial data was retrospectively extracted from chart review. Mean HbA1c (mHbA1c) over 10 years was calculated, as well as HbA1c variability estimated by standard deviation (HbA1c-SD) and coefficient of variation (HbA1c-CV). RESULTS: Fifty patients with T1D were included (30 females and 21 non-caucasians), with mean age and T1D duration of 25.6 ± 5.0 and 17.9 ± 6.1 years, respectively. The frequency of DPN was 24%. Higher mHbA1c (10.4 ± % vs 8.1 ± %; p < 0.001), HbA1c-SD (1.8 ± 0.8 vs 0.9 ± 0.4; p < 0.001), and HbA1c-CV (1.7 ± 0.8 vs 1.2 ± 1.1; p = 0.006) were observed in patients with DPN compared to others. SD-HbA1c and HbA1c-CV were associated with DPN, diagnosed by either clinical or NCS criteria, independent of mHbA1c, age and gender. CONCLUSIONS: Not only long-term glycemic control, but also its variability is associated with DPN in patients with T1D. Larger studies are required to confirm this finding.
RESUMO
Euphorbia hirta L., popularmente conhecida por erva andorinha, tem sido utilizada no tratamento de distúrbios respiratórios e como antiespasmódico. Esse trabalho foi realizado com a finalidade de determinar as características macroscópicas e microscópicas das folhas, caule e raiz dessa planta, uma vez que estas são as partes usadas popularmente. Algumas características de valor na sua diagnose foram apontadas e ilustradas por fotomicrografias. Reações de fitoquímica e a determinação do conteúdo de água e de cinzas foram realizadas no pó obtido da planta inteira, parte essa utilizada na fitoterapia Ayuverda. Na prospecção fitoquímica foram encontrados flavonóides, mucilagem, resinas e cumarinas. Na determinação do teor de água, de cinzas totais e de cinzas insolúveis em ácido, os valores encontrados foram 8,99%, 9,35%, 0,75%, respectivamente. Com o desenvolvimento deste trabalho foi possível obter parâmetros para o controle de qualidade das folhas, caule e raízes de E. hirta.
The Euphorbia hirta L. has been used in the treatment of respiratory disorders and as an antispasmodic. This work was carried out to determine the macroscopic and microscopic characteristics of the leaves, stems and roots of this plant, as these parts are commonly used. Some features of value in their diagnosis were identified and illustrated by photomicrographs. Phytochemical reactions and determination of water and ash contents were carried out in the powder obtained from the whole plant, the part used in Ayurveda phytomedicine. In phytochemical screening, we found flavonoids, mucilage, resins and coumarins. The values of water content, total ashes and acid insoluble ashes were 8.99%, 9.35%, 0.75%, respectively. The data obtained are important for the quality control of the leaves, stems and roots of E. hirta.

We obtain the κ-deformed versions of the retarded and advanced Green functions and show that their causality properties are blurred in a time interval of the order of a length parameter q=1/(2κ). The functions also indicate a smearing of the light cone. These results favor the interpretation of q as a fundamental length scale below which the concept of a point in space-time should be substituted by the concept of a fuzzy region of radius q, as proposed long ago by Heisenberg.
RESUMO
The oral findings of 12 patients with Moebius syndrome are described. Facial weakness, hypoplastic upper lip, microstomia, mouth-angle drooping, hypoplasia of mandible, gothic palate, tongue weakness, fissured tongue, tongue atrophy and open bite were found. In addition to describing the oral findings, this report discusses some implications for dental treatment of patients with this syndrome.
