Variação da temperatura superficial dos músculos masseter e temporal anterior durante o apertamento dental voluntário com placas interoclusais maxilares de duas diferentes espessuras

Muscle activity has been studied indirectly through analyses of temperature variation in skin surface temperature on the masticatory muscles. These procedure may be an important tool for clinical evaluation and assessment of the evolution of temporomandibular disorders, as well as monitoring the adopted protocol. Thus, its utilization for identified pathological alterations on blood circulation and/or on metabolic activity in subcutaneous tissues, such as the masticatory muscles, is justified. The aim of this study was to investigate the effect of occlusal splints’ thickness on the variation of surface temperature of the anterior temporal and masseter muscles during rest and clenching. It were analyzed 20 symptomatic subjects (10 males and 10 females) selected through the Research Diagnostic Criteria (RDC) questionnaire. Temperature expressed in degrees Celsius (ºC) was measured on the surface of both muscles measured with the aid of a digital thermometer with an infrared radiation reading system. The surface temperature of the anterior temporal and masseter muscles presented significant reduction during teeth clenching in relation to the mandibular rest position. However, there were no significant differences between conditions with and without occlusal splint or between the different thicknesses of splints analyzed. Masticatory muscles showed a considerable similar behavior for both sides, and no significant distinctions were observed between male and female patients.

Lymphoepithelial cyst in jugal mucosa

Mouth lymphoepithelial cyst is rare, with few cases reported in literature. The aim of this article is to describe a clinical case, focusing on clinical and diagnostic aspects, treatment and prognosis. The lesion was one year old and had developed as a fibrous nodule in the jugal mucosa of a 71-year-old leucoderma patient. Considering focal inflammatory fibrous hyperplasia, fibroma and mucocele as differential diagnosis, excisional biopsy was carried out. A cystic cavity limited by pseudostratified epithelium without projections into the conjunctive tissue, with lymphoid tissue within, was microscopically identified. Without postoperative adverse events, the one-year clinical followup confirmed the favorable prognosis of this kind of lesion.

Carcinoma de células escamosas em epitélio nasal de um hamster chinês: relato de caso

The squamous cell carcinoma (SCC) is a neoplasm that affect pets, production animals and exotic animals, and it’s very common in tropical countries like Brazil, once it develops a sparsely pigmented, stratified squamous epithelium and on surfaces mucosa exposed to ultraviolet action. The SCC is quite infiltrative but rarely causes metastases. Its occurrence in the nasal epithelium is widely reported in cats. This case is a chinese hamster (Cricetulus griséus), female, young, who developed a nasal nodule, and their only clinical sign was intense itching. The animal underwent surgery to perform an incisional biopsy, which was referred to the Veterinary Pathology Service of UNESP, campus of Araçatuba (SP) for histopathological evaluation. The material showed features consistent with squamous cell carcinoma well differentiated.

Lissencefalia em cães e gatos: revisão

Lissencephaly is a condition characterized by a lack of cerebral convolutions and sulci, which results from defective migration of nervous cells precursors in the telencephalus. The cause is presumably genetic. Lhasa-Apso dogs are most frequently affected, even though it may also occur in association with cerebellar hypoplasia in the Irish Setter, Wire-Haired Terrier and Samoieda breeds. This association was also reported in a cat. Clinical signs consist of dementia, aggressiveness, seizures, visual and olfactive dysfunctions, slow postural reactions and reduced menace response. Definitive diagnosis requires exams such as magnetic resonance imaging, cerebral biopsy or necropsy. There is no specific therapy for this disease, and seizures must be treated with anticonvulsants. The aim of this study is to review the literature regarding lissencephaly.

Biopsias luteais em vacas Nelore

The present study describes a technique to obtain consecutive luteal samples by colpotomy. The animals received an epidural anesthesia and local anesthesia (vaginal vault) and after ten minutes the vaginal vault was incised with a scalpel blade and tissue was dissected to provide access to the pelvic cavity and to retract the ovary into the vagina. Then, a luteal biopsy was performed with a Yomann biopsy nipper. Signs indicative of pain and stress during the vaginal vault incision, traction of ovary or luteal biopsy were observed only in two collections. However, these signs were observed in ten collections during dissection of the vaginal wall and peritoneum. The occurrence of ataxia was observed in 26 collections and it was usually related to a longer duration of the procedure. Ataxia could be divided in light (15/26), moderate (6/26) and severe (5/26). The occurrence of ovarian adhesions ipsilateral to the incision was evaluated only in the initial four collections. Adhesions were present in 16 collections. The protocol described above provided a safe and efficient method to acquire luteal samples. The low incidence of adhesions allows the consecutive use of females without any interference in subsequent ovulations and collections.

[Shape and function of the perineal muscles of viscacha (Lagostomus maximus).] Forma e funcao dos musculos perineais da viscacha (Lagostomus maximus). Pesquisa Veterinaria Brasileira 32(2):183-187. Departamento de Zootecnia, Faculdade de Zootecnia e Engenharia de Alimentos, Universidade de Sao Paulo, Av. Duque de Caxias Norte 225, Pirassununga, SP 13635-900, Brazil. E-mail: daniele@usp.br. Among the rodent species studied we can highlight the wide variation in the morphology of the male reproductive system. Thus, considering the ecological importance of rodents, and the large number and geographical representation of this animal, as well as shortages regarding the reproductive anatomy, we developed this study with viscacha, a South American histricomorph rodent. As this species has some very peculiar reproductive features, we described the gross anatomy of the perineal muscles and the role of copulatory behavior. The perineal region of viscacha is composed of five muscles, three of which are arranged in the superficial genitourinary diaphragm, as Musculus ischiocavernosus, M. bulbocavernosus and M. bulbospongiosus, and the muscles that lie at the pelvic diaphragm, M. levator ani and M. retractor penis. Therefore, we emphasize that the study of the pelvic floor in wild animals is of great value, then contribute to a better understanding of the mechanisms related to erection and ejaculation or collaborate with studies on the reproduction of animals.

Tratamiento conservador de tumor epitelial odontogénico calcificante asociado al canino inferior retenido: relato de caso clínico

The calcifying epithelial odontogenic tumour is a rare benign odontogenic neoplasm that accounts for approximately 1% of all odontogenic tumours. They are mainly located in the premolar/molar mandibular region, and are associated with an unerupted molar tooth. We present a literature review of the clinical, radiographic, pathological findings and treatment options of the calcifying epithelial odontogenic tumour, as well as describing the case of an calcifying epithelial odontogenic tumour associated with an impacted right mandibular in a 32-year-old male patient, who was treated conservatively, without no sign of recurrence of the lesion after five years.

Importância da avaliação da qualidade de vida em pacientes com endometriose

OBJETIVO: Examinar a relação entre aspectos clínicos e qualidade de vida em um grupo de pacientes com endometriose. MÉTODOS: Participaram desse estudo 130 mulheres atendidas durante o ano de 2008 em um centro multiprofissional de ginecologia especializado em endometriose. Este é um estudo de corte transversal realizado com uma amostra de conveniência. O diagnóstico de endometriose foi realizado por biopsia pós-laparoscopia, segundo os critérios da Sociedade Americana de Medicina Reprodutiva. Os dados clínicos e demográficos foram coletados a partir dos prontuários dos pacientes. A intensidade da dor foi avaliada com o uso de uma escala visual numérica (0-10) e os dados referentes à qualidade de vida foram coletados por meio do questionário SF-36. A análise dos dados consistiu de estatística descritiva e inferencial, teste de coeficiente de correlação de Spearman e o teste de Kruskal-Wallis para comparar escores entre grupos. RESULTADOS: As pacientes apresentaram idade entre 21 e 54 anos [ ou = 34, desvio padrão (DP)=6,56], sendo que 87% tinham terceiro grau completo e 75% eram casadas. Dezessete por cento referiram casos de endometriose na família. O tempo médio de manifestação dos sintomas foi de 4,5 anos (DP=6,6), 63% das pacientes estavam no estágio 3 ou 4 de endometriose, 36% das pacientes sofriam de dismenorreia severa ou incapacitante e a intensidade média da dor, segundo escala visual numérica, foi de 5,6 (DP=3,5). Os resultados sugeriram que o estadiamento da doença não é determinante da intensidade da dor. Por um lado, o tempo de manifestação dos sintomas também não apresentou relação com a intensidade da dor e com os escores do SF-36. Por outro, a intensidade da dor apresentou associação com menores escores em algumas escalas do SF-36. CONCLUSÃO: As pacientes com endometriose apresentaram escores de qualidade de vida inferiores ao da população em geral e inferiores a algumas outras patologias.

Ruolo dell'elastometria pulsata monodimensionale ad ultrasuoni (fibroscan) nella stadiazione della fibrosi epatica in pazienti sottoposti a trapianto ortotopico di fegato con recidiva di epatite C

PREMESSA: La progressione della recidiva d’epatite C è accelerata nei pazienti sottoposti a trapianto di fegato e ciò ha portato alla necessità di sviluppare nuove e validate metodiche non invasive per la quantificazione e la misura della fibrosi epatica. SCOPI: Stabilire l’efficacia dell’elastometria epatica (Fibroscan®) e dei parametri sierici di fibrosi, attualmente disponibili nella pratica clinica, per predire il grado di fibrosi nei pazienti sottoposti a trapianto epatico. METODI: La correlazione fra fibrosi epatica, determinata mediante biopsia epatica ed esame istologico, e Fibroscan® o indici clinico-sierologici di fibrosi (Benlloch, Apri, Forns, Fibrotest and Doppler resistance index), è stata studiata in pazienti che avevano ricevuto un trapianto ortotopico di fegato con evidenza di recidiva d’epatite da HCV. Un totale di 36 pazienti, con la seguente classificazione istologica: fibrosi secondom METAVIR F1=24, F2=8, F3=3, F4=1, sono stati arruolati nella popolazione oggetto di studio. Un totale di 29 individui volontari sani sono serviti come controllo. Le differenze fra gli stadi di fibrosi sono state calcolate mediante analisi statistica non parametrica. Il miglior cut-off per la differenziazione di fibrosi significativa (F2-F4) è stato identificato mediante l’analisi delle curve ROC. RISULTATI: La rigidità epatica ha presentato valori di 4.4 KPa (2.7-6.9) nei controlli (mediane e ranges), con valori in tutti i soggeti <7.0 KPa; 7.75 KPa (4.2-28.0) negli F1; 16.95 KPa (10.2-31.6) negli F2; 21.10 KPa nell’unico paziente F4 cirrotico. Le differenze sono state statisticamente significative per i soggetti controllo versus F1 e F2 (p<0.0001) e per F1 versus F2 (p<0.0001). Un cut-off elastografico di 11.2 KPagarantisce 88% di Sensibilità, 90% di Specificità, 79% di PPV e 95% di NPV nel differenziare i soggetti F1 dagli F2-F4. Le AUROC, relativamente alla capacità di discriminare fra i differenti gradi di fibrosi, evidenziavano un netto vantaggio per il Fibroscan® rispetto ad ognuno degli indici non invasivi di fibrosi. CONCLUSIONI: L’elastometria epatica presenta una buona accuratezza diagnostica nell’identificare pazienti con fibrosi epatica di grado significativo, superiore a quella di tutti gli altri test non invasivi al momento disponibili nella clinica, nei pazienti portatori di trapianto epatico ortotopico da cadavere con recidiva di HCV.
