Etiopatogenia e tratamento do deslocamento de abomaso em bovinos leiteiros de alta produção

The dairy business is in constant development, in order to achieve better results and higher profits to the producer, and this search for improvement has led to the selection of a herd more productive. But this has caused some problems heightened, among them the displacement of the abomasum, a disease that affects much of the high producing dairy herd. The main reasons are apparently related to the feeding management, with the abrupt changes that the animal suffers in the post partum period, with diseases that would cause abomasal atony favoring its displacement, among others. When affected, the animals lose their appetite and in milk production, and may even, in severe cases, death to come. Treatments described in literature are varied and there are conservative and chirurgical methods. The choice of a particular technique depends on the financial condition of the producer, the economic value of the cow and from personal experience and technique of the veterinarian. Understanding the clinical implications of displaced abomasum is necessary not only for its animal identification in the field and its appropriate treatment but also for finding the errors and inadequacies in the management system of production that trigger this disease

Considerações clínicas em implantes imediatos

The biological principles of osseointegration caused the rehabilitation treatment with osseointegrated implant become a safe, well alternative accepted by the dental community for the high success rate, allowing the preparation of functional and aesthetic prostheses in edentulous and partial patients. We passed the initial phase of functional vision for an aesthetic approach, too, depending on the demands of the patient and the quest for excellence by professionals. Over these last years, implant treatment has undergone many changes in surgical and prosthetic protocols. The less invasive surgical techniques and the development of restorative materials, especially ceramics allow the prosthetic rehabilitation of high functional quality and aesthetics. The installation of implants in sockets immediately after extraction of teeth involved by fracture, periodontal disease, endodontic lesions, is part of the arsenal of techniques for rehabilitating a number of advantages that we get to the outcome of multidisciplinary treatment. For this, we must consider several criteria in its planning as a fundamental unit, adjacent teeth, multiple losses, system, form and number of implants, type of retention of the prosthesis components, the patient expectation of the outcome perspective, gingival biotype, standard of ridge resorption, the smile line, etc. occlusal analysis. With the three-dimensional placement of the implant can immediately join the biological processes of repair of the socket, implant osseointegration, speeding treatment time. Much has been made by companies in the surface treatment of endosseous implants to be osseointegration shortened and restorative procedures started earlier, bringing benefits to the patient and professional. Among the main advantages we can emphasize the preservation of the structures adjacent to the teeth replaced, minor resorption of bone tissue involved...

Checklist de cirurgias da OMS: análise da segurança e comunicação da equipe cirúrgica de um hospital escola

WHO has launched the “Safe Surgery Saves Lives” program with the purpose to reduce damage to surgical patients and define safety standards specifically in order to reduce such patients’ morbi-mortality by providing surgery teams and hospital managers with orientation about the standards of safe surgery and a uniform service evaluation instrument for national and international surveillance. Hence, this study aimed at applying the WHO safe-surgery checklist to the surgical specialties of a university hospital and evaluating the team’s opinion about the influence of its application on the safety of surgical process and on the team’s interpersonal communication. It was a descriptive, analytical, qualitative field study conducted in the surgery facilities of a university hospital in a public establishment in São Paulo state. The checklist was applied to eight surgical specialties, resulting in a total number of 30 surgeries. Its application was conducted by the researcher in three phases: Sign in, Time out, Sign Out. Next, one member of the surgery team was invited to voluntarily participate in the study by signing an informed consent form and answering guiding questions. Thirty members of the surgery team participated in the study. Bardin’s Content Analysis Method was used to organize and analyze the data. As regards the safety provided by the checklist, the following thematic categories emerged: “It reduces risk and possible complications”; “It standardizes conducts and reviews safety steps”; “It allows for better understanding of the process”; and “It provides safety to the team as a whole”. The category “It is not included in the institution’s routine” emerged from the subjects’ statements when they understood that, in this form, the checklist does not provide safety to surgical procedures. As regards communication, two thematic categories emerged: ...(Complete abstract click electronic access below)

Avaliação do Efeito Fotodinâmico sobre o Crescimento in vitro de Pythium insidiosum

Photodynamic Therapy (PDT) is a therapeutic method which employs a photosensitizer and light to cause cellular death. The chemical compounds have low or none toxicity for hosts cells. Under the incidence of light, in an appropriated wavelength, these chemical compounds produce reactive oxygen which affects the biomolecules of the target-cells. The specific illumination of the affected area increases the selectivity of the therapy, since the photodynamic process occurs only in the irradiated area. Pythiosis, for instance, is a life-threatening emerging disease caused by a fungus-like organism called Pythium insidiosum. The disease occurs in man and other animals, being mostly observed in horses. Human pythiosis may present as ophthalmic, cutaneous-subcutaneous and systemic forms of lesions. Due to the fact that P. insidiosum is not a true fungus, it is refractory to most antifungal drugs and the treatment of the disease is difficult. Extensive surgery procedures, such as limb amputation, are the treatment of choice, however relapses may occur frequently. Although not totally effective, the use of immunotherapy associated to surgery have shown some results. Considering that pythiosis is an emerging disease few explored in its etiological and therapeutic aspects, which are limited and few effective, it is of great importance to encourage the development of researches for new strategies of treatment. In this sense, it was evaluated the effect of PDT on in vitro growth of the pathogen employing two chemical compounds as photosensitizer, porphyrin and chlorine, at different concentrations in combination with several energetic dosages. Porphyrin showed inhibition of growth at 25mg/mL with 100J/cm2 of energetic dosage and chlorine showed similar results employing low concentrations (0,7, 1,0 and 1,3mg/mL) with 70J/cm2 of energetic dosage...

Produção de biofilme por bastonetes gram negativos isolados de água de hemodiálise

No Brasil, 90% de pacientes com insuficiência renal crônica ou aguda dependem dos procedimentos de hemodiálise para remover produtos de degradação metabólica, excesso de água e de sais minerais do organismo, a fim de restaurar o equilíbrio ácido-base e eletrolítico. Entretanto, o processo de osmose reversa, que visa remover todos os íons da água, também remove o cloro, que exerce efeito bacteriostático sob diversas bactérias autóctones, que passam a se multiplicar na água. Entre os principais grupos dessas bactérias, estão os bastonetes Gram negativos não fermentadores (BGN) e os mais frequentemente associados a bacteremias, em pacientes de hemodiálise são Pseudomonas aeruginosa, Stenotrophomonas maltophilia e Burkholderia cepacia. Essas bactérias podem produzir biofilmes, o que torna sua eliminação do encanamento quase impossível. Assim, o objetivo do trabalho foi a análise de água e do dialisato, da Unidade de Hemodiálise de um Hospital Universitário, na pesquisa dos três BGNs citados. Também foram utilizadas 42 cepas previamente isoladas do mesmo local. Entre as 67 amostras de água, foram isoladas 8 cepas de Pseudomonas aeruginosa e as 50 cepas foram submetidas à pesquisa do gene rpoS, um dos responsáveis pela produção de biofilme. Esse gene foi observado em 20 (40%) cepas, sendo 16 (80%) P. aeruginosa, seguida por 3 (15%) cepas de S. maltophilia e 1 (5%) de B. cepacia. Essas cepas foram submetidas à produção de biofilme a 35ºC (temperatura ótima de crescimento) e a 20ºC (temperatura média da água no encanamento da Unidade de Hemodiálise), em aço inoxidável (material de muitos instrumentos cirúrgicos), PVC (matéria prima da tubulação) e plástico de poliestireno (capacidade de produção de biofilmes em diferentes materiais). Em poliestireno, somente 1 (5%) cepa de P. aeruginosa produziu biofilme a 35ºC e a 20ºC, 2 (10%) cepas foram... (Resumo completo, clicar acesso eletrônico abaixo)

The World Health Organization (WHO) has created a program “Safe Surgery Saves Lives”, focusing on reduce and minimize life threatening or cause serious risk to health for patients submitted to a surgery. This primary goal for this presented study is to apply the checklist from the WHO´s program for children´s surgery in a public university hospital, located in the countryside of São Paulo State, Brazil. Having the responses from professionals surgery´s team, there is an opportunity for evaluation of the features and easiest parts, which are filled in a quickly and in a easy way; focus, supporting and assistance; issues, such as lack of time for filling in, and viability of application of this protocol considering the improvement of the cross functions relationship, and quality of services, providing better assistance and support to the patient

Associações neuroleptoanalgésicas em equinos

The equine anesthesia is proven to be a high risk procedure, for both patient and anesthetist, compared to other animal species. In these conditions, a good anesthetic protocol that can deliver sedation, making access and manipulation easier, analgesia fair enough to realize cirurgical procedures, and minimal physiologic changes would be ideal. Since there aren’t any drugs suporting all these qualities, the Neuroleptoanalgesic Associations show themselves as a valuable technique to provide anesthetic quality and safety, possibly diminishing our drug of choice’s doses, therefore offering less fisiological changes and easier monetary access in some cases. This paper objective was to list all these associations found in literature, evaluating their advantages and practical applications

Schwartz-Jampel Syndrome: a paediatric dentistry approach

Schwartz-Jampel syndrome (SJS) is a rare recessive disorder characterized mainly by myotonia. As the clinical signs and symptoms are manifested in the oromaxillofacial region, paediatric dentists may be first choice of parents that seek information and assistance to their children. A female patient diagnosed with SJS was brought to our clinic for dental treatment with main complain of difficulty on oral hygiene and mastication due to tooth crowding. The treatment included preventive measures, extraction of a supernumerary tooth and the maxillary primary second molars. Furthermore, the patient was referred to orthodontic treatment for correction of tooth crowding. When dealing with children with confirmed diagnosis of SSJ, paediatric dentists should be understand the need of planning the dental treatment considering the characteristics and possible complications associated with the syndrome in order to reduce the risks to patients, especially when surgical procedures are necessary.

Innovation in pediatric surgery: the use of ultrasonic CVD tips: case report

The non-eruption of teeth due to highly keratinized gingival mucosa is a frequent event in the pediatric dentistry, which harms the oral aesthetics and function. A surgical excision of the involved area is indicated, exposing the non-erupted tooth. This procedure involves anesthesia and cutting instruments that may increase the fear and anxiety in young patients. The use of new technologies has avoided these instruments and has promoted more comfort to the patients. This study presents clinical cases in which gingivectomy was performed using the innovative method with an ultrasound-activated CVD tip. It was concluded that this method presented effectiveness, promoted more comfort, and less fear to the patients, making its use a viable alternative to pediatric surgery.

Uso de hialuronidato de sódio para tratamento de deslocamento anterior de disco articular com travamento bucal

Temporomandibular joint disorders causing limitation of mouth opening and pain may be related to the restriction of slipping or forward displacement of the mandibular condyle. Temporomandibluar arthrocentesis is the lavage of the joint and is regarded as a simple method that produces good results in patients with these symptoms. This article reports a case of disc displacement and closed lock in a patient who reported limited mouth opening and pain as the main symptoms. The treatment proposed was arthrocentesis and lavage, combining a corticosteroid with a sodium hyaluronate solution. It is concluded that arthrocentesis is a simple, efficient and barely invasive method for particular types of temporomandibular joint disorders and should be considered before opting for more invasive surgical procedures.

Aplicação do laser Er,Cr:YSGG em periodontia e implantodontia: revisão de literatura

Lasers are widely used tools in many therapeutic modalities in medical lasers and can be divided into low and high intensity. For the treatment of periodontal disease, lowintensity lasers are related to reduce the number of bacteria and to induce inflammatory and analgesic properties. The high intensity lasers can be used in surgical procedures, improving hemostasis, promoting more accurate cuts, removal of dental calculus as well as thermomechanical and photochemical interactions with tissue. The high-intensity laser Erbium impregnated with chromium: YSGG laser has shown satisfactory results when applied in endodontic, restorative denstistry, surgical procedures and non-surgical periodontal treatment. The purpose of this review is to evaluate the studies that investigated the effects of Er, Cr: YSGG laser on the morphology and biocompatibility of titanium and root surfaces irradiated with these lasers, even beyond the effect on the treatment of periodontitis and periimplantitis.

Uma opção terapêutica para o aumento da faixa de gengiva inserida: o enxerto de tecido conjuntivo livre

Several periodontal procedures have been described in the literature to correct mucogingival alterations or to achieve root coverage. The epithelized free gingival graft is a well established periodontal surgery to increase the width of keratinized gingiva with good stability in the long term follow up. However, this procedure is not commonly used in aesthetic areas since the grafted tissue presents differences of color and contrast. The free connective tissue graft emerges as a viable option to increase attached gingiva in areas where aesthetics results are required. The removal of an epithelized free gingival graft from the hard palate region creates a sore and raw surgical wound that slowly repairs, while the connective tissue graft produces only a line of incision that can be easily sutured promoting a more confortable outcome for the patient. This paper aims to report a case where a free connective tissue graft was used to increase the width of attached gingiva in a tooth with gingival recession. This technique presented satisfactory esthetics results, with a better contrast and color matching with the surrounding tissues.
