Resumo O objetivo deste estudo foi avaliar associação entre dor pré-operatória, ansiedade e impacto da condição bucal na qualidade de vida dos pacientes atendidos no serviço de Urgência Odontológica da Universidade Federal dos Vales do Jequitinhonha e Mucuri. Estudo transversal retrospectivo foi conduzido avaliando dados clínicos de 240 prontuários de pacientes com idades entre 18 e 65 anos. A dor foi mensurada pela Heft-Parker Visual Analogue Scale; ansiedade, pela Corah’s Detal Anxiety Scale e qualidade de vida, pelo Oral Health Impact Profile (OHIP-14). Associações foram analisadas pelo Teste qui-quadrado de Pearson (p < 0,05). Foi observada associação estatisticamente significante entre dor e pior qualidade de vida, com impacto nos domínios desconforto psicológico (p < 0,001), incapacidade física (p < 0,001), psicológica (p < 0,001) e social (p < 0,001). Ansiedade influenciou na pior qualidade de vida, com impacto nos domínios desconforto psicológico (p = 0,009), incapacidade fisica (p = 0,016), psicológica (p = 0,011) e desvantagem social (p = 0,028). Esse estudo é relevante para o planejamento de ações voltadas para a saúde bucal dos pacientes atendidos nos serviços de urgência odontológica, priorizando aqueles com maiores impactos psicossociais decorrentes dos problemas bucais.

Multiple Desmoplastic Cellular Neurothekeomas in Child: Report of the First Oral Case and Review of the Literature

Cellular neurothekeomas (CNs) are distinctive benign tumors of uncertain histogenesis, with predilection for the skin of the head and neck region. We describe the first case of multiple desmoplastic CNs (DCNs) affecting the oral cavity in a 9-year-old girl. Histopathologic evaluation showed a proliferation of spindle and epithelioid cells, forming nests and bundles, supported by exuberant fibrous stroma, as well as scattered multinucleated floret-like giant cells. The tumor cells were immunopositive for vimentin, CD63, CD56, whereas AE1/AE3, S100, CD34, α-SMA, GFAP, EMA, CD57 and NSE were negative. Ki-67 was <2%. Multiple DCNs should be considered in the differential diagnosis of oral nodular lesions.

Epidemiological profile of individuals with American cutaneous leishmaniasis in Jequitinhonha Valley, Brazil

This study aimed to characterize the epidemiological profile of patients with American cutaneous leishmaniasis (ACL) in 34 municipalities in Jequitinhonha Valley, Minas Gerais, Brazil, registered from 2005 to 2010 with the Regional Health Superintendence, using data from the Brazilian Disease Notification Information System. Among 281 cases, 156 (55.5%) were included in the study. A statistically significant difference was found in ACL among men between 21 and 60 years of age (P = 0.034) in relation to women and other age groups. Analysing the male sample, a significant association was found between ACL and occupation (P = 0.04). The cutaneous form occurred in 87.3% of cases. The medication most often employed was pentavalent antimony (87.3%), with cure achieved in 91.1% of cases. The epidemiological profile of ACL in the Jequitinhonha Valley is similar to that reported for other regions of Brazil, exhibiting a rural occupational nature and affecting men with low levels of schooling within the productive age.

Morphological characterization of the nasopalatine region in human fetuses and its association to pathologies

The nasopalatine region is composed of structures such as the vomeronasal organ and nasopalatine duct. The nasopalatine duct may provide the communication of the mouth to the nasal cavity in human fetuses and can be obliterated in an adult human. Knowledge on the development of the nasopalatine region and nasopalatine duct in humans is necessary for understanding the morphology and etiopathogenesis of lesions that occur in this region.

Basosquamous carcinoma: histopathological features

Basosquamous carcinoma (BSC) is a rare aggressive epithelial neoplasm with features of both basal cell carcinoma and squamous cell carcinoma, with a tendency toward local recurrence and a propensity for lymph node and distant metastases. The aim of the present study was to report the case of a 63-year-old Caucasian male with BSC in the auricular region.

Effect of topical application of different substances on fibroplasia in cutaneous surgical wounds

BACKGROUND

Fibroblasts on the edges of a surgical wound are induced to synthesize collagen during the healing process which is known as fibroplasia.

OBJECTIVE

The aim of this study was to determine the effect of the application of different substances on fibroplasia of cutaneous surgical wounds on rats.

MATERIALS AND METHODS

Forty-eight Wistar rats were divided into three groups. A surgical wound 1 cm in diameter and 1 mm in depth was created on the dorsum of each animal. The surgical wounds were submitted to the topical application of an alcoholic extract of 30% propolis, 70% alcohol, or 0.001% dexamethasone in a cream base every 12 hours. The animals were sacrificed three, seven, 14, and 28 days postoperatively. The specimens were histologically processed and stained with Masson's trichome. The assessment of fibroplasia was performed using a scoring system: (1) 5 to 25% collagen deposition; (2) 26 to 50% collagen deposition; (3) 51 to 75% collagen deposition; and (4) more than 75% collagen deposition.

RESULTS

There were statistically significant differences in collagen deposition between the substances at all postoperative evaluation times.

CONCLUSION

Propolis and alcohol promoted greater collagen deposition in surgical wounds than dexamethasone.

Oral and cutaneous melanoma: similarities and differences

Melanomas are malignant lesions stemming from the disorganized proliferation of melanocytes. This condition is more common on skin, but may also be detected in mucosa, such as in the oral cavity. The aim of the present study was to report similarities and differences between oral and cutaneous melanoma.

Study of intussusceptive angiogenesis in inflammatory regional lymph nodes by scanning electron microscopy

The aim of the present study was to verify the occurrence of intussusceptive angiogenesis in blood vessels from submandibular lymph nodes responsible for lymphatic drainage of the tongue. A surgical wound inflicted on the ventral tongue of male Wistar rats and submandibular regional lymph nodes were evaluated at different postoperative periods. Scanning electron microscopy (SEM) was used to observe 123 lymph nodes at times 2, 3, 7, 10, 14, and 21 postoperative days. During the analysis of the vascular models with SEM, intussusceptive angiogenesis was observed in all groups evaluated. This was more extensive on the second and third postoperative days (83.33% and 80%, respectively), representing in these groups the expansion of the vascular chain of lymph nodes. At 21 postoperative days, intussusceptive angiogenesis (42.85%) was suggestive of vascular remodeling.

Angioarchitecture of the ventral surface of the tongue from Wistar rats

The goal of this study was to describe the angioarchitecture of the ventral surface of the tongue from Wistar rats using a vascular corrosion casting technique associated with scanning electron microscopy (SEM). Six Wistar rats were used for the vascular casting method with Mercox resin. Following the resin polymerization, the tongue of each animal was dissected and corroded in a 5% sodium hydroxide solution. Once the corrosion and drying of the specimens were completed, the specimens were mounted on aluminum stubs, coated with carbon and gold and analyzed under SEM. The results showed that the ventral surface of the tongue presents simple, even and abundant vasculature constituted by a vascular plexus consisting of a superficial vascular network and by the ranine veins. The superficial vascular network, made up of the ascending and descending branches, presents as a loose network, with little morphological variation between the capillary loops.

Extensive myiasis infestation over a squamous cell carcinoma in the face. Case report

Human myiasis is a parasitosis found in tropical and underdeveloped countries. It usually affects the elderly, unhealthy and mentally disabled individuals. It is caused by dipterous that lay their eggs in necrotic or infected tissues, although areas of the body that are apparently healthy can also be affected. Frequently the fly deposits several eggs on the peripheral parts of scratches and wounds. The treatment of myiasis involves mechanical removal of the larvae with hemostatic pincers. Larvae rupture must be avoided. Application of topical ether or similar volatile substance is useful. Preventive approach measures, including basic health care, hygiene, access to primary health service, and safe water and drainage, are fundamental to prevent human myiasis. The authors present a case report of myiasis infestation over an extensive head and neck squamous cell carcinoma from a 72-year-old patient living in a rural area. Approximately 200 larvae were removed and the patient was taken to the hospital's head and neck surgery service.

Vascular corrosion casting technique steps

The vascular corrosion casting technique produces a replica of vascular beds of normal or pathological tissues. Once associated with scanning electron microscopy (SEM), this technique provides details of the three-dimensional anatomic arrangement of the vascular replica, which is the main advantage of this method. The present study is intended to describe the steps of the vascular corrosion casting technique and the different ways to perform them. them.

[Clinical-epidemiologic profile of paracoccidioidomycosis at the Stomatology Department of São Lucas Hospital, Pontificia Universidade Católica of Rio Grande do Sul]

The aim of the article was to describe clinical and epidemiological features of 61 oral paracoccidioidomycosis cases from the Stomatology Department of São Lucas Hospital, analyzed from July 1976 to June 2004. The State of Rio Grande do Sul is an endemic region due to ecoepidemiologic conditions, that are favorable for the development of the yeast. Men are the most affected gender, with 58 (95%) affected compared to 3 (5%) women. Ii is most prevalent (70.5%) between 40 and 59 years of age. Agricultural labor was the most common occupation with 27/61 (44.3%) patients. Tobacco smoking was prevalent in 52 (85.3%) of the sample, and alcoholism was a frequent finding. All the patients showed stomatologic manifestations, with ulcers and mulberry-like stomatitis the most prevalent, these oral lesions were also observed in many anatomical sites. Alterations were present in 32 (65.3%) of the pulmonary radiographs.

Estudo das alterações morfológicas causadas pela uretana em modelo de carcinogênese bucal DMBA-induzida

A proposta deste trabalho resultou da necessidade de se avaliar o potencial carcinogênico da uretana, em concentragoes mais baixas, a partir do modelo experimental de carcinogenese bucal DMBA-induzida. Cem hamsters sírios dourados foram separados em cinco grupos experimentais. 0 grupo 1 recebeu aplicações topicas de uretana 0.5% na borda lateral da língua; grupo 2, uretana 6%; grupo 3 uretana 0.5% + DMBA; grupo 4, uretana 6% + DMBA, e o grupo 5 — DMBA (controle positivo). Os dados obtidos mostraram que a uretana a 0.5% e 6% não induziu alterações histolOgicas nos grupos 1 e 2. A formação de carcinomas nos animais tratados com uretana e DMBA ocorreu em proporções menores quando comparada com o grupo controle positivo (DMBA). A uretana a 0.5% e 6% reduziu a carcinogenicidade do DMBA, e não apresentou potencial carcinogenic° de iniciação, promoção e/ou progressão.
