Proteção de Bromeliaceae para evitar a formação de criadouros de Aedes aegypti (Diptera: Culicidae)

As plantas da família bromeliaceae constituem criadouros de Aede aegypti. O presente estudo de campo mostrou que medidas mecânicas podem ser uma solução para o controle do mosquito nessas plantas. Na região norte do estado do Paraná, área de infestação por Ae. aegypti, q5 bromélias foram monitoradas durante um ano após receberem tratamento com palha de madeira e cascas de árvore. Nesse período não foram observadas formas imaturas de mosquitos, o que sugere que o uso deste material natural pode servir como medida complementar aos programas de controle vetorial.

A formação de professores e suas relações com cultura e sociedade: a educação escolar indígena no centro das atenções

This paper reflects the current situation surrounding indigenous teacher education by means of the construction of a dialogue among three educators, two of them non-indigenous educators involved with indigenous school education and one indigenous educator committed to the education of his people. Teacher education, situated in a socio-cultural way, is the center of attention in this paper. ""Listening"" as a way of talking with the ""other"" is one of the theoretical focuses of this exercise between teacher educators and teachers, which uses dialogue as a means to increase awareness. In the dialogic process mentione, it was possible to realize how rich a dynamic between educators from different cultural contexts can be. The desire of the indigenous educator and his/her people to contribute their ideas to the construction of the indigenous school became evident. This shows the great challenge for non-indigenous educators seeking to contribute to the organization of the school education of distinct indigenous nations.

Management of Chronic Unilateral Hematuria by Ureterorenoscopy

Background and Purpose: Chronic unilateral hematuria is characterized by intermittent or continuous gross hematuria that cannot be diagnosed using standard radiology and hematology methods. In the past, it was managed with partial or total nephrectomy. In the age of minimally invasive procedures, however, endoscopy has enabled more accurate diagnosis and management. We analyzed our experience with transurethral ureterorenoscopy using a flexible ureteroscope to determine the feasibility and success of endoscopic management of renal hematuria. Patients and Methods: We reviewed the records of 13 patients who presented with chronic unilateral hematuria, in whom radiologic and laboratory tests failed to reveal the source of bleeding. In the cases in which the lesion was identified, after complete inspection of the collecting systems, the bleeding site was treated ureteroscopically with a holmium: yttrium-aluminum-garnet ( YAG) laser. Results: Follow-up ranged from 4 to 60 months ( mean 26 mos). During the follow-up of the 13 patients, 11 remained symptom-free, with only one session of flexible ureterorenoscopy necessary. Relapse occurred in two patients after 4 months and 6 months, respectively; during a second session of flexible ureteroscopy, the bleeding site was successfully identified and cauterized with a holmium: YAG laser. No surgical complications occurred. Conclusions: Conservative treatment of patients with chronic unilateral hematuria should always be considered. Laser ureteroscopic treatment is an excellent method and should be considered as the first option for the management of chronic unilateral hematuria.

Thyroid Function After Unilateral Total Lobectomy

Objective: To evaluate the incidence of postoperative hypothyroidism among patients who underwent unilateral total lobectomy and identify related factors. Design: Retrospective medical record analysis. Setting: Oncological center and private clinic. Patients: From March 1996 to July 2005, 228 euthyroid patients underwent unilateral total lobectomy for benign diseases; 168 had all the information required for inclusion in this study. Main Outcome Measures: Serum levels of thyrotropin and antithyroidal antibodies were assessed, as well as ultrasonographic evaluation of the remaining thyroid lobe and review of all histological specimens, with emphasis on lymphocytic infiltration. Hypothyroidism was defined as thyrotropin level greater than 5.5 mU/L. Results: Most patients were female (88%), with a median (range) age of 45 (16-72) years. Hypothyroidism occurred in 61 cases (32.8%), during a median follow-up period of 29 months (range, 6-108 months). Statistically related factors included higher preoperative thyrotropin levels (2.1 mU/L among hypothyroid patients vs 1.2 mU/L in euthyroid patients; P<.001), smaller thyroid remnant volume (3.9 mL vs; 6.0 mL, respectively; P = .003); right vs left lobectomy (P = .006), and higher thyroperoxidase antibody serum levels (P = .009). Conclusions: Postoperative hypothyroidism appeared in 32.8% of the cases in this series, especially among patients with elevated preoperative thyrotropin and postoperative thyroperoxidase antibody levels, after right lobectomy and when a smaller thyroid remnant was left. After confirmation with larger prospective series, these results may support the indication for early postoperative hormone supplementation in these instances.

Diffuse analgesic effects of unilateral repetitive transcranial magnetic stimulation (rTMS) in healthy volunteers

We investigated the analgesic effects of unilateral repetitive transcranial magnetic stimulation (rTMS) of the motor cortex (M1) or dorsolateral prefrontal cortex (DLPFC) in two models of experimental pain in healthy volunteers. Two studies were carried out in parallel in two groups of 26 paid healthy volunteers. The effects of active or sham rTMS (frequency, 10 Hz; intensity, 80% resting motor threshold) applied to the right M1 or DLPFC were compared in a double-blind randomized cross-over design. In the first series of experiments, we analyzed the effects of rTMS on thermal (heat and cold) detection and pain thresholds measured on both hands and the left foot, by standardized quantitative sensory testing methods. In the second series of experiments, we measured the effects of M1 or DLPFC rTMS on the threshold and recruitment curves of the RIII nociceptive reflex evoked by ipsilateral electrical stimulation of the sural nerve and recorded on the biceps femoris of both lower limbs. In both studies, measurements were taken before and up to 60 min after the end of rTMS. Active rTMS of both M1 and DLPFC significantly increased the thermal pain thresholds, measured for both hands and the left foot, this effect being most marked for cold pain. These effects, which lasted at least 1 h after rTMS, were selective because they were not associated with changes in non-painful thermal sensations. By contrast, the second study showed that rTMS of M1 or DLPFC had no significant effect on the threshold or recruitment curve of the nociceptive flexion RIII reflex. Our findings demonstrate that unilateral rTMS of M1 or DLPFC induces diffuse and selective analgesic effects in healthy volunteers. The lack of effect on the RIII reflex suggests that such analgesic effects may not depend on the activation of descending inhibitory systems. (C) 2009 International Association for the Study of Pain.

Good surgical outcome in discordant ictal EEG-MRI unilateral mesial temporal sclerosis patients

Purpose:Video electroencephalography (vEEG) monitoring of patients with unilateral mesial temporal sclerosis (uMTS) may show concordant or discordant seizure onset in relation to magnetic resonance imaging (MRI) evidence of MTS. Contralateral seizure usually leads to an indication of invasive monitoring. Contralateral seizure onset on invasive monitoring may contraindicate surgery. We evaluated long-term outcome after anteromesial temporal lobectomy (AMTL) in a consecutive series of uMTS patients with concordant and discordant vEEG findings, uniformly submitted to AMTL on the MRI evidence of MTS side without invasive monitoring. Methods:We compared surgical outcome of all uMTS patients undergoing vEEG monitoring between January 1999 and April 2005 in our service. Discordant cases were defined by at least one seizure onset contralateral to the MRI evidence of MTS. Good surgical outcome was considered as Engel`s class I. We also evaluated ictal SPECT concordance to ictal EEG and surgical outcome. Results:Fifty-four patients had concordant (C) and 22 had discordant (D) scalp EEG and MRI. Surgical outcome was similar in both groups (C = 74% versus D = 86%). Duration of follow-up was comparable in both groups: C = 56.1 +/- 20.7 months versus D = 59.8 +/- 21.2 months (p = 0.83, nonsignificant). Discordant single-photon emission computed tomography (SPECT) results did not influence surgical outcome. Discussion:Surgical outcome was not influenced by contralateral vEEG seizure onset or contralateral increased flow on ictal SPECT. Although vEEG monitoring should still be performed in these patients, to rule out psychogenic seizures and extratemporal seizure onset, a potentially risky procedure such as invasive monitoring may not only not be indicated in this patient population, but may also lead to patients erroneously being denied surgery.

Activation of Selected Shoulder Muscles During Unilateral Wall and Bench Press Tasks Under Submaximal Isometric Effort

STUDY DESIGN: Controlled laboratory study. OBJECTIVE: To assess the activation of 7 shoulder muscles under 2 closed kinetic chain (CKC) tasks for the upper extremity using submaximal isometric effort, thus providing relative quantification of muscular isometric effort for these muscles across the CKC exercises, which may be applied to rehabilitation protocols for individuals with shoulder weakness. BACKGROUND: CKC exercises favor joint congruence, reduce shear load, and promote joint dynamic stability. Additionally, knowledge about glenohumeral and periscapular muscle activity elicited during CKC exercises may help clinicians to design protocols for shoulder rehabilitation. METHODS: Using surface electromyography, activation level was measured across 7 shoulder muscles in 20 healthy males, during the performance of a submaximal isometric wall press and bench press. Signals were normalized to the maximal voluntary isometric contraction, and, using paired t tests, data were analyzed between the exercises for each muscle. RESULTS: Compared to the wall press, the bench press elicited higher activity for most muscles, except for the upper trapezius. Levels of activity were usually low but were above 20% maximal voluntary isometric contraction for the serratus anterior on both tasks, and for the long head triceps brachii on the bench press. CONCLUSIONS: Both the bench press and wall press, as performed in this study, led to relatively low EMG activation levels for the muscles measured and may be considered for use in the early phases of rehabilitation.

Influence of treadmill training on motor performance and organization of exploratory behavior in Meriones unguiculatus with unilateral ischemic stroke: Histological correlates in hippocampal CA1 region and the neostriatum

This study examined the effects of motor stimulation via treadmill on the behavior of male gerbils after external carotid ischemic brain lesion. The animals were assigned to five groups; ischemic with no stimulation (SIG), ischemic with stimulation (SIG 12/24/48/72 It after surgery), non-ischemic with no stimulation (CC), non-ischemic with stimulation (CE) and sham, surgery without occlusion with no stimulation (SH). All the animals were tested in the open-field (OF) and rotarod (RR), 4 days after surgery in order to evaluate exploratory behaviors and motor performance. Data were submitted to one-way variance (ANOVA) and Dunnett`s post hoc comparisons. SIG and SIG 12 groups showed a significant decrease in motor response (crossing) when compared to the control group (CC) (F = 20.65, P < 0.05) in the OF. SIG 12 group showed an increase in grooming behavior (F = 23.136, P < 0.05) and all ischemia groups (SIG, SIG 12/24/48/72) spent less time on the RR (F = 10.40, P < 0.05), when compared to the control group (CC). Histological analyses show extensive lesions in the hippocampus and neostriatum for all groups with ischemia (SIG, SIG 12/24/48/72), which are structures involved in the organization of motor behavior. Interestingly, the most pronounced damage was found in animals submitted to motor stimulation 12 h after ischemia which can be correlated to the increased number of grooming behavior showed by them in the OF. These findings suggest that motor stimulation through treadmill training improve motor behavior after ischemia, except when it starts 12h after surgery. (c) 2007 Elsevier Ireland Ltd.

Hypertrophy and neuron loss: structural changes in sheep SCG induced by unilateral sympathectomy

Recently, superior cervical ganglionectomy has been performed to investigate a variety of scientific topics from regulation of intraocular pressure to suppression of lingual tumour growth. Despite these recent advances in our understanding of the functional mechanisms underlying superior cervical ganglion (SCG) growth and development after surgical ablation, there still exists a need for information concerning the quantitative nature of the relationships between the removed SCG and its remaining contralateral ganglion and between the remaining SCG and its modified innervation territory. To this end, using design-based stereological methods, we have investigated the structural changes induced by unilateral ganglionectomy in sheep at three distinct timepoints (2, 7 and 12 weeks) after surgery. The effects of time, and lateral (left-right) differences, were examined by two-way analyses of variance and paired t-tests. Following removal of the left SCG, the main findings were: (i) the remaining right SCG was bigger at shorter survival times, i.e. 74% at 2 weeks, 55% at 7 weeks and no increase by 12 weeks, (ii) by 7 weeks after surgery, the right SCG contained fewer neurons (no decrease at 2 weeks, 6% fewer by 7 weeks and 17% fewer by 12 weeks) and (iii) by 7 weeks, right SCG neurons were also larger and the magnitude of this increase grew substantially with time (no rise at 2 weeks, 77% by 7 weeks and 215% by 12 weeks). Interaction effects between time and ganglionectomy-induced changes were significant for SCG volume and mean perikaryal volume. These findings show that unilateral superior cervical ganglionectomy has profound effects on the contralateral ganglion. For future investigations, it would be interesting to examine the interaction between SCGs and their innervation targets after ganglionectomy. Is the ganglionectomy-induced imbalance between the sizes of innervation territories the milieu in which morphoquantitative changes, particularly changes in perikaryal volume and neuron number, occur? Mechanistically, how would those changes arise? Are there any grounds for believing in a ganglionectomy-triggered SCG cross-innervation and neuroplasticity? (C) 2011 ISDN. Published by Elsevier Ltd.

Unilateral hearing loss: benefits and satisfaction from the use of hearing aids

A unilateral hearing loss is characterized by reduced hearing in one ear. The problems caused by sensory deprivation can be minimized with the use of hearing aids (HA). Aim: To analyze the correlation between the prescribed grain and the insertion gain difference and with the results obtained regarding the benefit and satisfaction with the use of hearing aids in unilateral hearing impaired patients. Materials and Methods: Prospective study with 15 subjects, mean age of 41.6 years, of both genders, users of hearing aids effectively. We used the International Questionnaire Results for hearing aids (International Outcome Inventory for Hearing Aids - IOI-HA), measured with a probe microphone. Results: The mean values in the analyses of the IOI-HA per item were positive and higher than four points. In relation to the objective measures, the frequencies in which we obtained the gain values which were closer to the target were: 1K Hz, 2K Hz and 500 Hz, respectively. Conclusion: The satisfaction of individuals using hearing aid unilaterally is not completely correlated to the prescribed gain, because even if the target is not being reached in some frequencies, the individuals were pleased as to the use of their hearing aids.
