Efeitos esqueléticos e dentários decorrentes da expansão rápida maxilar

This study evaluated the maxillary transversal changes caused by the rapid maxillary expansion (RME) accomplished by Hyrax appliance. Sixteen children from both genders were selected and treated, with ages between 7.7 to 10.8 years, who presented unilateral or bilateral posterior crossbite. Postero-anterior radiographs were taken at the beginning of the treatment, end and post-retention period. The treatment promoted an average opening of 8.8 mm of IMD (intermolar distance), 2.33 mm of IAD (interapex distance) and none of IID (interincisal distance). At the end of retention period, relapse was observed, with a decrease of 4.3 mm of IMD, 1.23 mm of IAD, a non-significant enlargement of IID (0,38 mm).These results confirm the significant influence of Hyrax appliance on transverse dimensions, represented by enlargement of IMD and IAD and its effectiveness to solve posterior crossbites.

Estabilidade oclusal a longo prazo de Classe II, divisão 1, após tratamento com extração de pré-molares

Patients are looking for esthetic and functional changes when seeking orthodontic treatment and expect the remaining of a stable occlusion. Occlusion stability is one of the goals of the orthodontist; however, dental relationships changes in long-term can occur leading to a relapse of the treatment. Teeth and shape of arches tend to return to the original form, been the retention phase important after the appliance removal, even after several years of post-treatment. This article approaches a submission of a clinical case of Class II division 1 treated with extraction of premolars analyzing its long-term stability.

Via Láctea: História (parnasiana) de uma paixão

Poesias (1888), Olavo Bilac’s first book, contains Via Láctea, a collection of sonnets of love that, in frank rupture with the romantic sentimentalism, is characterized by neoclassical moderation and contention. Universalizing treatment of the themes results in concealment of the particular circumstances in which the poems were composed. It is intended in these few pages to evidence the links between these texts and known episodes of the courtship of the poet and Amélia de Oliveira, the sister of Alberto de Oliveira, with the goal of providing an understanding of Via Láctea as a “love diary” in which the painful stations of a frustrated passion were registered.

Transconversações queer: sussurros e gemidos lusófonos Quatro cadelas mirando a(s) Psicologia(s)

To follow the cartographies’ path throughout pernicious (dis)courses of the capitalized Psychology. Com/positions both around desires and binary desires raised from binary norms, followed by (un)folding the beds, the “family”, the clinical thought and practice, the research, the geni(t)ality. Profane writing. Epistemic micro-rebellion promised and incorporated by the ass, because in the beginning it was and it (also) is the ass. A distorted and a trans-barked way of writing by four female dogs looking at Psychology. To (d)enounce the ménage that psychologists, supported by a history without history, intent to build over their empty beds which are blemished by modern Truth(s). Towards a minor psychology, this is a schizo-queer-analytic manifesto on desires-pleasures-senses within the lusophone transcontemporaneity. In the absence of a conclusion, we propose rather the provocative state that only a bitchy-psychology-to-come could edify the visibility of the invisible human. Otherwise, we believe it is in the promising barks that Psychology can be withdrawn from its betraying and betrayed contention of multitudes

Replantation as treatment for extrusive luxation

In the treatment of extrusive luxation cases, it is important that the repositioning of extruded tooth in the socket is done as soon as possible. If this does not occur, periapical clot becomes organized and makes replantation difficult reposition. In this article the patient referred to the Clinics for dental trauma sustaining extrusive luxation of the maxillary right central incisor. The patient reported having suffered a bicycle accident 12 days before, which caused traumatic tooth injuries. The repositioning was attempted without success and an alternative form of treatment was necessary to solve the case. Intentional tooth replantation, which is the deliberate extraction of the tooth and its replantation, was indicated. This technique allows clot removal and correct repositioning of the extruded tooth. Care should be taken as endodontic treatment is required for the prevention of subsequent infection-related resorption. Intracanal dressing with calcium hydroxide was used for 30 days before final root filling. Splint, systemic antibiotics and avoidance of further damage to the root surface is also important. After 49 months, showed clinical and radiographic characteristics of normality and demonstrates the availability of this technique to adversity in trauma.

Ophthalmic parameters in adult Shih Tzu dogs

Ocular surface diseases are often diagnosed in brachycephalic dogs. The ophthalmic parameters of the Shih Tzu dogs are evaluated in this study since this breed is among the most commonly affected by these diseases. In this study, ophthalmic parameters of this breed were partly studied under physical restraint. Schirmer tear test, breakup time test, aesthesiometry, biomicroscopy, non-contact specular microscopy, laser flaremetry, applanation tonometry, ultrasonography and ophthalmoscopy were carried in 48 eyes of 24 male and female dogs, aged from two to four years, weighing between 5 and 10kg. All dogs were from a breeding kennel. Descriptive statistics were applied to the data. Mean and standard error for Schirmer tear test was 26.145±0.803mm min-1; breakup time test, 13.668±0.538s; and aesthesiometry, 2.395±0.071cm. The biomicroscopy evaluation showed that 70.83% of the eyes had medial entropion; 42% caruncular trichiasis; 33% distichiasis, 27% mild paracentral corneal opacity; and 13% corneal melanosis. Mean and standard error for endothelial cell density was 2221.591±20.161cells mm-2; endothelial cell hexagonality, 63.770±1.805%; endothelial cell area, 451.895±4.179mm2; central corneal thickness, 0.490±0.007 mm; laser flaremetry, 1.720±0.216PC ms-1; applanation tonometry, 16.118±0.460mmHg; axial length, 20.255±0.134mm; lens thickness, 6.624±0.031mm; anterior chamber, 4.064±0.109mm; and vitreous chamber, 9.565±0.054mm. Ophthalmoscopy findings were not different from previous reports for other breeds. The results showed that the ophthalmic Shih Tzu parameters did not differ from other breeds according to data in the literature, except for the breakup time and Cochet-Bonnet aesthesiometry.

Bronchoalveolar lavage (BAL) in tapirs (Tapirus terrestris) withMycobacterium tuberculosis

This paper describes the in vivo Bronchoalveolar lavage (BAL)technique by endoscopy in tapirs (Tapirus terrestris) with clinicalsigns of tuberculosis. The technique was performed in two tapirs, male and female,from Curitiba Zoo, Paraná, Brazil. A flexible endoscope and a polyethylene catheterwere used after the chemical restraint of the animals. For BAL technique, 60mL ofsaline 0.9% were infused with a polyethylene catheter, introduced by the endoscope'working channel, and 15mL of BAL were recovered, analyzed and submitted tocytocentrifugation. Slides were stained by Papanicolaou, periodic acid-Schiff (PAS)and Ziehl-Neelsen methods contained high quantity of inflammatory cells on lightmicroscopy (macrophages 27.5%, lymphocytes 0.5%, neutrophis 67% and eosinophis 5%).BAL samples were submitted to culture, bacilloscopy and PCR and were negative forboth animals. Based on this study, it was concluded that the bronchoalveolar lavagetechnique in tapirs is feasible, simple, noninvasive, practical and fast, providingan important clinical information in vivo regarding the functionalstatus of the lower respiratory tract.

Efeito do estresse crônico e benzodiazepínicos no reparo ósseo: estudo histológico em ratos

Stress is an environmental factor that may predispose individuals to depression. Benzodiazepines have been prescribed as effective drugs in these situations. The purpose of this study was histological evaluate of the effect of chronic stress and benzodiazepine drugs on bone healing. Bone cavities were created in both tibias of 40 male rats were divided into two groups: Control and Treaty. In this, the stressor stimulus was applied 40 days pre-operative and all post-operative days until sacrifice in the morning for 2 hours, by immobilizing restraint. These animals also received diazepam benzodiazepine group, daily, at a concentration of 5mg/Kg/peso body within 15 days of preoperative. In groups of five animals were sacrificed at 7, 14, 30 and 60 days post-surgery. At 7 days postoperatively, while the control group exhibited tissue rich in fibroblasts, the treated group showed newly formed tissue with few fibroblasts and capillaries along with lymphocytes and macrophages. At 14 days postsurgery, the control group showed newly formed trabecular bone while the treated group progressed to thin trabecular bone with numerous osteoblasts on their borders. At 30 days post-operative bone healing is complete in both groups. At 60 days post-operative characteristics observed in the treated and control groups are similar to the previous period, but with more advanced osteogenesis.

Dental care for cerebral palsy patients using auxiliary resources to inhibit pathological tonic reflexes

Cerebral paralysis is a chronic illness that affects the central nervous system. In this article the author describes the techniques used at CAOE (Odontological Center for Assistance to patients with special needs) to restraint CP patients during dental treatment, because they present some pathological reflexes which interfere in their odontological assistance. Also it shows how to perform a special physical restraint and how to keep the mouth open by using simple tools including a homemade one. All the devices used during the dental treatment in cerebral palsy patients, such as the physical restraint with bands or sheet to wrap them up, cylindrical pad or cushion made of a soft material, or simple tools including a homemade one to keep the mouth open are usually and safely used in CAOE. All these simple devices are necessary, because there are no available funds for the acquisition of expensive material or equipment. Despite of a shortage of resources we can easily and efficiently assist these patients.

Oportunidades de melhoria na gestão de resíduos em empresas distribuidoras de eletricidade: o caso da AES Eletropaulo

A gestão de resíduos em distribuidoras de eletricidade é bastante complexa, pois enquadram-se em vários tipos (valorizados ou não) e gerados em grande quantidade. Em 2009, a AES Eletropaulo gerou quase quatro mil toneladas de resíduos não perigosos, subdivididos em 30 tipos. Uma divisão por materiais, após desmontagem e separação dos diferentes materiais contidos nos fios, cabos, chaves, isoladores com ferragem e para-raios, subiria o valor da venda em R$ 600 mil. Isso geraria cerca de 214 toneladas de porcelana que, moídas, poderiam substituir as 210 toneladas de brita compradas anualmente pela concessionária para uso em subestações. Cerca de 160 toneladas de porcelanas intactas poderiam ser utilizadas na confecção de gabiões para contenção de encostas. Além disso, peças de ferro galvanizado poderiam ser decapadas e novamente galvanizadas para reaproveitamento.
