The aim of this study was to test the effect of agricultural and forestry land use on the structure of mayfly assemblages in low-order streams. Twenty-nine headwater streams were investigated in the state of São Paulo. We analyzed 15 streams in pristine areas (mixed tropical rainforest, semideciduous forest and dense tropical rainforest), and 14 streams covered with sugarcane, eucalyptus and pasture. Mayfly richness obtained by rarefaction curves was higher in pristine areas (21 genera), especially in mixed and semideciduous forest when compared to land use (9 genera), where values were particularly low in sugarcane plantation (3 genera). The non-metric multidimensional scaling (NMDS) ordination showed clear difference in mayfly assemblages between land uses and pristine areas, supported by analysis of similarity (R=0.67, p=0.001). In partial redundancy analysis (pRDA), the environmental descriptors that best explained differences in assemblage structure were Riparian, Channel and Environmental Inventory (RCE) index score, percentage of fine sediment stream substrate, water pH and land elevation. Our results show that agricultural and forestry land use has a strong negative effect on the structure of mayfly assemblages. These results also support the use of mayfies as environmental indicators, as some genera were sensitive to changes in land use, while others responded to naturally occurring changes in the study area. © 2014 Academia Brasileira de Ciencias.

Purpose: To analyse the rate of clinical recurrences in Brazilian patients with Vogt–Koyanagi–Harada (VKH) disease after early high-dose corticosteroid treatment. Methods: Retrospective study including patients treated with early high-dose corticosteroids (prednisone, 1–1.5 mg/kg/day, or 3-day 1 g methylprednisolone pulsetherapy) within 1 month from disease onset followed by slow taper (at least 6 months). Patients with a minimum 12-month follow-up were subdivided based on the presence of disease recurrence or persistence after 6 months from initial presentation into: acute–resolved (AR, no recurrences), chronic–recurrent (CR), and chronic–recurrent with subretinal fibrosis (SRF). Recurrences were defined as the presence of clinical and/or fluorescein angiography findings. Results: Twenty-nine patients (58 eyes) with a median follow-up of 65 months were included. Six (21 %), 11 (38 %) and 12 (41 %) patients were allocated to AR, CR, and SRF groups respectively. Though having received treatment within 1 month of onset, median time to initial treatment differed among groups (11, 15, and 25 days, in AR, CR, and SRF groups respectively). Intensity of immunosuppression, cataract development, and longer time to achieve logMAR visual acuity ≤0.8 differed significantly among the groups, being more severe in SRF group. HLA-DRB1*0405 allele followed the same trend, though not reaching significance (0.5 in AR group, 0.6 in CR, and 0.8 in SRF). Conclusion: VKH disease in Brazilian patients evolved to chronic–recurrent disease in 79 % of cases; 38 % developed subretinal fibrosis, in spite of similar initial treatment regimens. Time to initiate treatment influenced outcomes. © 2015, Springer-Verlag Berlin Heidelberg.

Objective: To describe the prevalence of medical visits and associated factors in an adult population of a medium-sized municipality in Southern Brazil. Methods: A cross-sectional population-based study was carried out in a representative random cluster sampling in Lages, state of Santa Catarina, Brazil. The reference population comprised adults (aged 20 to 59 years) and 2,022 individual were interviewed. The outcome was medical visits during the 12 months prior to the study. Data related to the type of service (public/private) and evaluation of this services were also collected. The independent variables were gender, race/skin color, marital status, income, schooling, health self-perception, nutritional status, self-reported diabetes, high blood pressure, smoking, and alcohol-related problems. Poisson regression was carried out and the prevalence rate was obtained. Results: The prevalence of medical visits was 76.0% (95%CI 73.6-78.4). Women, those with higher income, those who had diabetes, smokers, ex-smokers, those having alcohol-related problems, and those who evaluated their health negatively reported a higher prevalence of medical visits. We also found that among lower income people, medical visits to the Unified Health System (Sistema Único de Saúde) were more frequent. Conclusion: Prevalence of medical visits varied according to the population studied. Health policies at the three government levels must acknowledge such inequality to subsidize actions in the sector to suggest equality policies.

The aim of this study was to estimate the prevalence of insufficient physical activity and to find the factors associated to this outcome in Lages, Santa Catarina, Brazil (2007). A cross-sectional population-based study was carried out in a representative sample of individuals between 20 and 59 years of age (n=2,051). Physical activity was estimated using the short version of the International Physical Activity Questionnaire. Insufficient physical activity was defined as less than 150 minutes per week spent in moderate or vigorous physical activity. The prevalence of insufficient physical activity was 29.6% (95%CI: 27.6; 31.7). The associated factors were to be male, obese, have high income, and negative self-perception of health status. The prevalence of insufficient physical activity was lower than reported by other Brazilian studies. Studies that distinguish different types of physical activity can contribute to a better understanding of the problem. The implementation of public policies that encourage the practice of regular exercises is required.

This study aims to report the incidence of Calodium hepaticum among dogs and cats, pets or stray animals, captured by the Zoonosis Control Center (CCZ) in Lages, Santa Catarina, Brazil. Fecal samples from 108 pet dogs and eight pet cats, and from 357 stray dogs and 97 stray cats, captured by CCZ, were analyzed within the period from July 2010 to November 2012. Coproparasitological exams were performed by techniques of sedimentation, centrifuge-flotation, and simple flotation. Among 465 fecal samples from dogs and 105 from cats, the overall spurious infections for C. hepaticum eggs were 1.05%. For dogs, this positivity was 0.43% and for cats it was 3.81%. The two positive dogs were stray and out of the four cats, three were stray and one was a pet. Although the occurrence of C. hepaticum eggs was low, these data reveal the existence of infected rodents, especially in public places, since, out of the six infected animals, five (83.33%) were stray. These results are discussed and analyzed with an emphasis on the risk to public health.

Autogenous bone is still considered the gold standard, and the applicability of autogenous bone grafts is well established. However, the possibility of second harvesting from the same donor region remains unclear. The aim of this study was to perform a prospective evaluation of hard tissue deposition in the mandibular ramus after bone block harvesting using cone beam computed tomography (CBCT). Twenty-two patients with indications for augmentation procedures using autogenous bone from the mandibular ramus were selected. Three CBCT scans were performed with a tomographic guide before bone harvesting (T1) and at 14 days (T2) and 6 months (T3) after the surgical procedures. Measurements were obtained in 2D (area, mm2) and 3D (volume, mm3), and were subsequently compared. In the 2D analysis, the mean bone formation rate was 56%, while for the 3D analysis the mean rate was 9.7%. Despite this difference, there was a significant correlation between area and volume measurements. Our findings demonstrated the presence of hard tissue in the mandibular ramus at 6 months after bone harvesting, which suggests that it would be possible to reuse the same region for a second block harvesting. However, the second bone harvesting would involve less bone for transplantation when compared to the first bone harvesting. © 2013 International Association of Oral and Maxillofacial Surgeons.

Introduction: Diabetic foot infections are a difficult problem to solve, often requiring hospitalization and exposing patients to the risk of amputations. Identification of the most prevalent pathogens is useful for administration of antibiotic therapy, and can reduce mutilations. Objective: To identify the microbiological profile and resistance to antimicrobial drugs in a series of patients with infected diabetic feet. Material and methods: an epidemiological, retrospective and descriptive study based on analysis of medical records from diabetic patients with plantar lesions who underwent surgical treatment over a 24-month period at a public hospital. Data were collected on age, sex, length of hospital stay, cultures from lesions, antibiotic therapy administered, bacterial resistance and surgeries conducted, with statistical analysis of means and standard deviations. Results: There were 66 admissions of diabetic patients, the majority elderly people (77%). Hospital stays ranged from 2 to 29 days, with a mean of 12.42. There were 91 surgical procedures, resulting in some kind of amputation in 65% of cases. The most common bacterial group was enterobacteria (47%), followed by staphylococci (27%). Three patients (4.5%) had multi-resistant organisms. Resistance to clindamycin was the most common at 39 admissions (59%), followed by resistance to cephalexin, seen in 24 admissions (36%). Conclusions: Diabetic foot infections were most often caused by germs found in the community, in particular the enterococci. Bacterial resistance was very widespread and was most commonly associated with drugs for oral administration, in particular clindamycin and cephalexin. © 2014, Sociedade Brasileira de Angiologia e Cirurgia Vascular.

The effects of hydroalcoholic extract from the leaves of Gochnatia polymorpha sp. floccosa on the contractile responses of the isolated guinea-pig ileum were investigated using a force displacement transducer amplifier connected to a physiograph. Isolated ileum preparations were set up for recording of isometric contractions in 5 mL jacketed organ baths containing oxygenated Krebs-Henseleit solution at 37°C under 1 g of load. G. polymorpha floccosa extract inhibited the contractile responses in a dose-dependent manner against different agonists. The profile of inhibition was noncompetitive to acetylcholine, histamine, serotonin and bradykinin- induced contractions. IC50s (and maximal inhibitions) values obtained were 247 μg mL-1 (83.1%), 818 μg mL-1 (72.62%), 450 -μg mL-1 (75.82%) and 210.09 μg mL-1 (97.35%), respectively. These findings support the popular use in folk medicine of this plant as an antispasmodic on smooth muscles contractions. © 2011 Academic Journals Inc.

Biting behaviour of pumas at the moment of killing their prey is mentioned in the literature as being delivered either to the throat, nape of the neck and base of skull. Detailed anatomic descriptions of it are, however, largely absent in literature. In this article, the biting behaviour of a puma while attacking a peccary is described based on the perforations found on the skull of the prey. An observer looking at the prey-predator struggle would mistakenly conclude that the bite was meant to reach the throat region with the intent of suffocation, when in fact the bite reached and damaged the ventral and posterior region of the skull, and the spinal cord. According with the most likely hypothesis derived from matching a puma skull with that of the collared-peccary, the predator grasped it with its forepaws from behind, and bit at the upper throat region while the peccary held its head back exposing the throat region, allowing the upper canines to reach and damage the occipital bone and auditory bulla. Although there are no marks on the vertebrae, the evidence from the skull match indicate that the penetration of the upper canines into the skull allowed the top incisors to reach exactly where the atlas vertebrae and the occipital condyle connect. The lower canines held the upper part of the cranium, puncturing slightly at the postorbital process. The unusual behaviour of biting the skull from below may be partially due to the presence of an extended nuchal crest in collared-peccaries, which prevent predators to reach the spinal cord from above. © 2013 by Unisinos.

This study aimed to identify the medicinal arboreal species from riparian forests at three small farms in Urubici Municipality, Santa Catarina State, Brazil, and relate their ecological features to the possibilities of their use for restoration of degraded riparian environments. In order to survey individuals with circumference at breast height (CBH) ≥15 cm, the quadrant method was adopted. The sampled specimens were herborized, incorporated into the Herbarium LUSC and categorized according to their medicinal use, employed part, frequency, dispersal syndrome (anemochory, autochory and zoochory), ecological group (pioneer, early secondary, late secondary) and use for forest restoration. Of the 240 sampled specimens, 197 belonging to 22 species of 15 families were potentially medicinal. The most abundant families were Euphorbiaceae, Rosaceae, Myrtaceae, Sapindaceae, Lauraceae and Anacardiaceae. More than 85% potentially medicinal species had zoochoric dispersal syndrome, around 78% were categorized as early secondary and pioneer, and around 88% were recommended for restoration. Medicinal arboreal species are quite common in degraded riparian forests along Canoas River. They can provide genetic resources for restoration and adequacy of permanent preservation areas (PPAs) to the environmental legislation; moreover, they are exploitable non-timber forest products.
