Nectar production has an important role in pollinator attraction and successful fruit production in many selfincompatible angiosperm groups. The reproductive biology of Passiflora actinia was studied here and related to nectar dynamics. Passiflora actinia presented a temporal segregation of male and female functions at the beginning of anthesis. Due to the movements of floral verticils, the anthers were positioned in a way that favors pollination two hours before the stigmas reached the same position. The nectary consisted of an epidermis with stomata and a parenchyma rich in starch, which was hydrolyzed during anthesis. The nectary organization is probably associated with the continuous production of nectar during anthesis as well as with the high mean nectar concentration. Hand pollination tests indicated that Passiflora actinia is obligately xenogamous, depending on large bees for pollination, specifically the carpenter bee Xylocopa augusti. The continuous production of nectar may increase the number of bee visits, thus favoring pollen flow.

O abuso de drogas, lícitas ou ilícitas, é um dos principais problemas sociais e de saúde pública do mundo, sendo assim o contato do cirurgião dentista com pacientes dependentes dessas substâncias é inevitável. Estudos sugerem que o uso de drogas aumenta as manifestações orais, como alterações do fluxo salivar, desgaste dental, cárie, doença periodontal, xerostomia e dor. Por isso, o profissional deve estar preparado para atender esses pacientes, e ter conhecimento sobre as limitações e possíveis interações, principalmente em tratamentos invasivos, seja em ambiente hospitalar com o paciente sedado ou no consultório com anestésicos locais. O objetivo deste trabalho é relatar um caso de monitoramento da pressão arterial, saturação de oxigênio e frequência cardíaca, durante um procedimento com múltiplas exodontias em uma paciente dependente química. Apesar da paciente se manter estável, foi constatado aumento da pressão diastólica no pós-operatório, podendo estar relacionado com a vasoconstrição causada pelo uso da maconha e crack, e a ação da epinefrina do anestésico. Esse aumento se relaciona com alterações no sistema simpático e parassimpático, por isso a importância de se conhecer as substâncias empregadas no procedimento e em medicamentos receitados. Conclui-se que é preciso aprimorar o conhecimento das alterações fisiológicas, químicas e neurológicas que envolvem esses pacientes, para um tratamento odontológico seguro, e quando necessário em conjunto com uma equipe multiprofissional, saber encaminhar o paciente e identificar problemas de saúde não somente bucais.

Posterior mandible region is considered a highly predicable place for primary stability during dental implant placement. Although, this region can present a significant decrease in bone density, which can lead to implant dislocation during insertion. The present case reports an unusual dislocation of dental implant in a 59 old healthy patient's mandible and a secure solution for this kind of complication. During the drilling, bone quality type IV was observed. In sequence, implant was abruptly inserted in the perforation site and dropped into the bone marrow. Panoramic radiograph showed the implant inside bone marrow, close to mandibular base. The implant was removed through the surgical site. The screw of the implant prosthesis transfer was used to reach the displaced implant. A second implant with the same dimensions as the first one, differing by the external hexagon, was inserted into the same implant site. Therefore, the authors strongly recommend the use of the presented technique prior to osteotomy on mandibular body, reserving the second in the impossibility of reaching the internal connection of the displaced implant.

______________________________________________________________________________________________________________________Resumo: Produzir leite dentro dos requisitos de qualidade previstos pela legislação brasileira ainda é um desafio a ser superado por muitos produtores. O presente estudo teve por objetivo avaliar a qualidade do leite produzido por produtores da região Norte Pioneiro do Estado do Paraná. Foram selecionados 25 produtores de leite dos municípios de Santo Antônio da Platina, Carlópolis, Jacarezinho, São José e Siqueira Campos, sendo coletadas três amostras de cada produtor nos meses de janeiro, fevereiro e março de 2013, totalizando 75 amostras. As amostras foram encaminhadas ao Laboratório da Associação Paranaense de Criadores de Bovinos da Raça Holandesa para Contagem Bacteriana Total (CBT), Contagem de Células Somáticas (CCS) e as análises de proteína, gordura, lactose, sólidos totais, caseína e extrato seco desengordurado (ESD). As médias de gordura, proteína, ESD e CBT estavam dentro dos padrões, enquanto que a média de CCS extrapolou o limite máximo determinado pela legislação. Avaliando os resultados individualmente, verificou-se que 26 amostras (34,7%) apresentaram pelo menos um requisito em desacordo com os limites previstos pela legislação, sendo quatro amostras (5,3%) com resultados abaixo do estabelecido para gordura, onze amostras (14,5%) acima do limite previsto para CBT e 13 (17,3%) para CCS. A CCS apresentou correlação positiva com a porcentagem de proteína e negativa para a lactose, enquanto que a CBT não apresentou correlação com nenhum dos componentes avaliados.Palavras-chave: Contagem de Células Somáticas; Contagem Bacteriana Total; Componentes do Leite; Instrução Normativa número 62.Abstract: Produce milk in compliance with the quality requirements established by Brazilian legislation is still a challenge to be overcome by many producers. The objective of this study was to evaluate the quality of milk produced by producers of Pioneer North of Paraná State. Twenty-five milk producers from the cities of Santo Antônio da Platina, Carlópolis, Jacarézinho, São José, and Siqueira Campos were selected and three samples of each producer were collected in January, February and March 2013, totalling 75 samples. The samples were sent to the Laboratory of Paraná Association of Holstein Cattle Breeders for Total Bacterial Count (TBC), Somatic Cell Count (SCC), and analyses of protein, fat, lactose, total solids, casein and non-fat dry extract (NDE). The average values for fat, protein, NDE and TBC were in accordance with the standards, while the average of SCC exceeded the limit determined by the legislation. Evaluating the results individually, it was found that 26 samples (34.7%) had at least one requirement in disagreement with the limits established by the legislation, being four samples (5.3%) with results below the established limit for fat, eleven samples (14.5%) above the limit for TBC and 13 (17.3%) for SCC. SCC showed positive correlation with the percentage of protein and negative ...

Aspiration and ingestion of teeth, dental prostheses and other foreign bodies in maxillofacial injuries is a known complication necessitating prompt recognition and early treatment to minimize potentially serious and, sometimes, even fatal consequences.  However, an aspirated or ingested foreign body does not always produce untoward affects and may be overlooked when no acute respiratory distress is evident or multiple life-threatening injuries are present. Here, we report a case in its presentation; the patient underwent extraction of a left upper third molar. After extraction, alveolar irrigation was performed with syringe, needle and sterile saline. the patient ingested the irrigation needle. The patient was properly referred to the emergency room of the hospital of Santa Fé do Sul and referred to the care of the general surgeon, who removed the needle with endoscopic removal under sedation. Clinicians must be aware that the instrument used for dental treatment are mostly small and there is a risk of these falling into the oropharynx and being swallowed or inhaled. The paper also emphasizes that attention to the potentially serious consequences and to offer guidance on management.

Orotracheal intubation is considered the most delicate maneuver performed by anesthesiologists, and failure to manage the airways is one of the main causes of possible complications that can be catastrophic during its performance, thus requiring good team planning. Anatomical and / or physiological characteristics, such as limited mouth opening, a condition often found in patients suffering from fractures of the zygomatic arch or who have some abnormality in the temporomandibular joint (TMJ), can characterize a difficult airway, which demands attention greatest of the professional. Therefore, in order to overcome the obstacles that may occur during a difficult or unexpected intubation, new tools have been used, such as videolaryngoscopy in which an intubation device containing miniature video cameras is used in order to allow the operator has an indirect view of the glottis to increase success rates and decrease intubation time. The aim of the present study is to report a clinical case of a trauma victim, with limited mouth opening, who underwent intubation with the aid of a video laryngoscope after failed attempts at conventional intubation.
