Não preferência para alimentação e antibiose em cultivares de amendoim a Stegasta bosquella (Chambers) (Lepidoptera: Gelechiidae)

This work aimed to evaluate the attractiveness, non-preference for feeding and antibiosis in straight and runner growth habit peanut cultivars to Stegasta bosquella (Chambers). Eight cultivars were evaluated, four of straight growth habit (IAC Tatu, IAC 22, IAC 8112 and IAC 5) and four of runner growth habit (IAC Runner 886, IAC 147, IAC 125 and IAC 503). Free-choice and no-choice feeding tests were performed, using pairs of overlapped leaf discs with 1.0 cm diameter, which were placed in Petri dishes where third instar larvae of S. bosquella were released. The attractiveness to the larvae was assessed in predetermined times, in addition to the dry mass consumed. In the antibiosis assay, the biological parameters were evaluated: period and viability of larvae, pre-pupae, pupae, and total, weight of larvae and pupae, sex ratio and longevity. None of the runner growth habit cultivars exhibited non-preference for feeding-type resistance. Among the straight growth habit cultivars, IAC 5 and IAC 22 were the least attractive and consumed in the free-choice feeding test, and IAC 5 and IAC 8112 were the least attractive in the no-choice test. The runner growth habit cultivars IAC 147 and IAC Runner 886 affected the larval survival of S. bosquella, exhibiting antibiosis-type resistance. For the straight growth habit cultivars, IAC 22 and IAC 8112 affected the larval viability, presenting antibiosis-type resistance. The straight and runner growth habit cultivars did not influence the biological parameters of weight of pupae, sex ratio and longevity of S. bosquella.

Características da carcaça e alometria dos tecidos de cabritos F1 Boer × Saanen

Com o objetivo de avaliar as características de carcaça e a alometria dos cortes comerciais e dos tecidos de cabritos F1 Boer × Saanen, 35 animais foram abatidos ao atingirem 5, 10, 15, 20 e 25 kg de peso vivo (PV). A dieta dos animais foi composta de leite de vaca nos primeiros 49 dias e ração à vontade do sétimo dia até o abate. Os cortes foram obtidos após o resfriamento da carcaça e a perna foi dissecada em músculo, osso e gordura. O PV teve efeito linear decrescente no rendimento de carcaça fria e na área de olho-de-lombo por kg de carcaça. Os pesos de perna, paleta e pescoço em relação à carcaça fria decresceram linearmente, mas houve efeito quadrático sobre o rendimento de costelas e lombo. O crescimento de paleta, pescoço e perna foi isométrico (b=1) ao do corpo, enquanto o das costelas e do lombo foi mais lento (b¹ 1). Os músculos da perna cresceram igualmente, a gordura mais lenta e os ossos mais rapidamente que a perna, enquanto o desenvolvimento da gordura subcutânea foi mais tardio que o da intermuscular. Para obtenção de carcaça de 8 a 11 kg com rendimento superior a 44%, boa proporção de músculo e gordura com menor perda durante o resfriamento, recomenda-se abater os animais com PV entre 20 e 25 kg, mas, se o objetivo for carcaça de menor peso, o abate dos animais deve ser feito ao final do aleitamento com aproximadamente 10 kg de peso corporal.

Epidemiological aspects of dog bites considering biter dogs and victims

The aim of this study was to characterize dog bites using data on biter dogs and victims. An exploratory cross-sectional study was performed using 203 records of individuals who had attended in public health services in 2009 in the municipality of Araçatuba, São Paulo, Brazil, after they had been bitten by a dog. Over 70% (92/129) of the biter dogs were male and most of them (71%) received as a gift. Dog owners reported companionship as the main reason for acquiring the dog. The victims who were children were predominantly male, while the victims who were elderly were predominantly female. Most children were bitten on the head/neck, while adults were bitten on the hands/feet and lower limbs (p<0.0001). The owner of the dog was known in 83.2% of cases. However, rabies observation of the biter dog following the attack was only reported in 59.4% of cases. Situations involving aggression were related to dogs having escaped from their home (18.7%) or roaming free on the streets (17.0%). The analysis of biting dog characteristics using information obtained from dog bite victims and biting dog owners can help direct the medical treatment for dog bite victims. Moreover, concepts of responsible dog ownership can reduce the occurrence of bites.

The osteoradionecrosis (ORN) during long was considered as hum type of osteomyelitis spent bone, being one of the major complications of radiotherapy head and neck. This complicate are presents despite advances in the treatment of cancer patients, Therefore, the objective of this work was to emphasize the main factors predisposing ORN, its clinical features and treatment through a literature review.

Acessos cirúrgicos a articulação temporomandibular: revisão de literatura

The choice of surgical approach to diseases that affect the pre-auricular region has been subject of much discussion in the literature. Access pre-hearing, have been used with high compliance rate of success, and during the history of surgery, several modifications were made in this approach with the goal of reducing the irreversible consequences especially regarding common in condylar fractures as paralysis and facial scars. The views range from the indication of surgical treatment for all fractures, until the conviction that no fracture of the bone segment should be surgically treated. Therefore, this study is of relevance, since offers surgeons warn about the care on the anatomical structures involved in these surgical approaches and describe, seeking a comparison between them, the advantages of them by means of a literature review covering from the extensive bouts of Bellinger (1940) and Al-Kayat (1979) that provide a broad view of the surgical field to access modified and increasingly smaller as the endaural (2001) which not only allows a satisfactory field of aesthetics as maintenance the patient without any signs of scarring.

Raiz dentária impelida para o seio maxilar após exodontia: uma opção de tratamento

Introduction: Upper teeth, especially first premolars and molars, can have a close anatomical relationship with the floor of maxillary sinus. For this reason, accidental displacement of dental roots into the sinus could happen during exodontic procedures. Objective: Description the treatment performed to remove a tooth root within the maxillary sinus, displaced during an extraction procedure. Case Report: Female patient, 39 years of age, which reported being subjected to the extraction of the element 26 for about two months. The patient was reported by the practitioner who performed the extraction that a root was pushed into the maxillary sinus. The treatment plan included surgery to remove the root within the maxillary sinus. Final Comments: Clinicians should be careful during extractions, to prevent these accidents. However, if such complications occur, access to the maxillary sinus is the best treatment option.

Tumor odontogênico queratocístico: considerações clínico-cirúrgico

Introduction: The tumor odontogenic keratocyst (toq) is a benign disorder, which is controversial in its diagnosis and treatment. It is characterized by a true neoplasms arising from remnants the dental lamina. It occurs predominantly in the angle mandible, which may or may not be related to a tooth and whose importance is due to its aggressive behavior and high recurrence rate. The causes of the high recurrence rates. The thin capsule and friable tissue may favor the toq retention of epithelial debris and, moreover, the presence of satellite cells in the lesion site is responsible for the increased proliferative capacity of clinical entity. Objective: To present the peculiarities toq inherent in using a clinical case of toq in mandible. Case report: TOQ in the jaw in patient, 16 years old male presenting important lesion radiographically radiolucent related to the impacted tooth. Final comments: In consideration of the high rate of recurrence chosen treatment proved effective and was not any evidence of recurrence.

Trauma traqueal associado à fratura mandibular: relato de caso

Introduction: The mandibular injuries account for about 20% to 50% of cases of facial fractures. Some consider the jaw the second most commonly fractured bone of the skull, and is the only mobile bone of the facial framework, which results in decreased stability compared to the trauma. When one takes into account the degree of airway obstruction in patients with facial fractures, the problem becomes much more serious since it is one of the most troubling complications of trauma. Objective: the relevance of the topic is aimed to report a case of a patient victim of mandibular fracture associated with trauma to the trachea. Case report: Case report: Patient 24 years old patient with tracheal trauma concomitant mandibular fracture surgically treated in conjunction with the thoracic surgeon. After 5 months postoperatively, the patient is in good condition general, no complaints. Final comments: This form is observed that the key to proper treatment of tracheal trauma associated with facial fractures is the knowledge of the type of injury, and an accurate diagnosis multidisciplinary.

Tumor odontogênico queratocístico: relato de caso

Introduction: The odontogenic keratocyst tumor (OKT) derived from dental lamina rests with particularities and specific histological features, with high rates of relapse and aggressive clinical behavior. Presents certain predilection for males, affecting the mandible of 60% to 80% of cases may be related to impacted tooth 25 to 45% of cases. Objective: To highlight the clinical, histopathological and imaging procedures of the OKT, as well as discuss the treatment of this injury. Case Report: To report a case of 10 years of age to look for the orthodontist to correct anterior open bite was observed in panoramic radiography radiolucent area in the region of the body of the mandible associated with pathological inclusion of the lower premolar. It was performed an incisional biopsy of the lesion and the histopathologic diagnosis was odontogenic keratocyst tumor. It was performed a CT scan to assess the extent of the injury and its relation to anatomic structures. How to conduct, we opted for the extraction of the deciduous molar and enucleation of the lesion, preserving the premolar included. The same goes on clinical and radiographic control 18 months, after removal of OKT obtaining the eruption of premolar that was involved in the injury. Final Comments: It is necessary to adopt protocols that include dental care knowledge of oral diagnosis, medical history and careful clinical evaluation without forgetting the need for histopathological confirmation.

Reabsorção condilar progressiva: revisão de literatura

The progressive condylar resorption is a irreversible complication that can result in malocclusion and facial deformity that can happen especially in postoperative orthognathic surgery of mandibular advancement or combined surgery. Predominantly affect young women, bearers of malocclusions of skeletal class II and with incidence of temporomandibular disorders prior to surgical treatment. Its exact etiology and pathogenesis remain unclear. The purpose of this article is to make a literature review of the last 10 years on the progressive condylar resorption. For this, we used the Medline database for articles in the English language. Then, 13 articles were found, evaluated and compared on predisposing factors, etiology, diagnosis and clinical management.
