Chronic obstructive pulmonary disease is progressive and is characterized by abnormal inflammation of the lungs in response to inhalation of noxious particles or toxic gases, especially cigarette smoke. Although this infirmity primarily affects the lungs, diverse extrapulmonary manifestations have been described. The likely mechanisms involved in the local and systemic inflammation seen in this disease include an increase in the number of inflammatory cells (resulting in abnormal production of inflammatory cytokines) and an imbalance between the formation of reactive oxygen species and antioxidant capacity (leading to oxidative stress). Weakened physical condition secondary to airflow limitation can also lead to the development of altered muscle function. Chronic obstructive pulmonary disease presents diverse systemic effects including nutritional depletion and musculoskeletal dysfunction (causing a reduction in exercise tolerance), as well as other effects related to the comorbidities generally observed in these patients. These manifestations have been correlated with survival and overall health status in chronic obstructive pulmonary disease patients. In view of these facts, the aim of this review was to discuss findings in the literature related to the systemic manifestations of chronic obstructive pulmonary disease, emphasizing the role played by systemic inflammation and evaluating various therapeutic strategies.

This study was performed to standardize parasite egg counting in feces of sheep by TF-Test, in addition to compare this test to the Gordon & Whitlock technique (G&W). Twenty-four lambs were artificially infected with Haemonchus contortus throughout 12 weeks. At the end of this time, faecal samples were taken and animals were slaughtered for worm identification and counting. G&W and TF-Test methods were carried out on each fecal sample. Both tests showed Haemonchus eggs in 95.8% of the samples (P>0.05). The correlation coefficients (r) between fecal egg counts (FEC) using G&W × Total Worm Count (TWC) were r=0.52 (not transformed data) and r=0.85 (transformed data); between FEC by TF-Test × TWC were r=0.51 (not transformed data) and r=0.87 (transformed data). Other 100 fecal samples were taken from naturally infected sheep. In these animals, the G&W and TF-Test methods showed 85% and 86% of fecal samples positive for Strongylidea eggs, respectively (P>0.05). Also in those animals, Eimeria oocysts were found in 33% of fecal samples by TF-Test, whereas in the G&W only 12% were positive (P<0.001). For Strongyloides spp., TF-Test showed 15% of positive fecal samples, whereas G&W showed 5% (P<0.05). In conclusion, both methods were efficient to diagnose gastrointestinal nematodes and TF-Test was superior to diagnose oocysts of Eimeria spp. and eggs of Strongyloides spp; conversely, Strongylidea eggs counting using TF-Test was underestimated.

Purpose: To describe alterations observed in patients with congenital clinical anophthalmia and the occurrence of association with other ocular and extra ocular abnormalities. Methods: An observational retrospective study was conducted evaluating 12 patients with congenital clinical anophthalmia at Faculdade de Medicina de Botucatu-UNESP, between 1992 and 2005. In those patients it was observed the ocular abnormalities, severity, laterality, follow-up and to systemic abnormalities associated. The congenital clinical anophthalmia have been associated to major severity abnormalities extra-oculars, mainly when the anophthalmia was bilateral, such agenesis of corpus callosum, others craniofacial anomalies and cardiac defects. In the cases unilateral, the alteration associated more frequently was the facial asymmetry, showing the direct correlation between anophthalmos and development of orbit and face. Conclusion: There was relation between congenital clinical anophthalmia and ocular abnormally and extra-ocular abnormally. Patients with bilateral anophthalmos disease have more severe alterations. anophthalmia congenital attends a course with abnormalities of development of the face.

Objective Determining conditions regarding possible zoonosis transmission risk based on Ilha Solteira-São Paulo citizens' habits aimed at establishing concrete recommendations for the corresponding local authorities to reduce some risk factors. Methods100 focalized interviews were held on Ilha Solteira's urban perimeter during April 2008. The people interviewed were adults who lived or worked in houses in the study area. Results This research found a significant number of cat and/or dog owners who allowed their pets to stay in internal areas of their houses. They did not define a specific place for animals to defecate and/or urinate or did not arrange appropriate final disposal of such waste. Conclusion Local authorities must make greater efforts at educating Ilha Solteira pets' owners and providing them with information and encouraging greater citizen commitment and awareness to improve habits related to caring for pets/animal sand reducing zoonosis transmission risk factors.
