Abstract: objective: to correlate the ophthalmic complications in patients with extra-orbital malignant tumors with the site of origin and histopathologic diagnosis of the tumors by computed tomography. methods: twenty-nine patients diagnosed to have extra-orbital malignant neoplasms, with clinical and radiological evidence of orbital involvement, were studied by computed tomography. no patient had previous treatment of the tumor. results: squamous cell carcinoma was the most common neoplasm (28%), followed by basal cell carcinoma (14%). the most frequent ophthalmic complications were proptosis (38%), epiphora (24%) and ocular pain (24%). decreased visual acuity was noticed in 14% of the cases. the most common sites of origin of the tumors were the maxillary sinus (28%), ethmoidal sinus (17%) and skin and subcutaneous tissue of the face (17%). ocular proptosis was mainly caused by non-carcinomatous and ethmoidal sinus tumors. epiphora was more often noticed in carcinomas and maxillary sinus tumors. decreased ocular motility, visual disturbance and ocular secretion were the commonest ophthalmic complications in patients with ocular anexial tumors. on the other hand, ocular pain was the most frequent feature in patients with soft tissue tumors of the face. conclusion: the authors suggest that, in patients with epiphora and nasomaxillary mass, carcinoma of the maxillary sinus should be considered as the first diagnosis. non-carcinomatous tumors, like sarcomas and lymphomas, should mainly be considered in patients with proptosis and nasoethmoidal mass.

Abstract: systemic diseases, primary orbital diseases and extraorbital lesions extending into the orbit may lead to ocular proptosis. eleven patients with ocular proptosis caused by non previously treated extraorbital malignant tumors were studied with computed tomography. nonepithelial neoplasms were the most common tumors (82%) including three rabdomyosarcomas (27%), three non-hodgkin's lymphomas (27%), and other sarcomas in two patients (18%). squamous cell carcinoma (9%), burkitt's lymphoma (9%) and poorly differentiated carcinoma (9%) were also identified. the most common primary sites of the tumors were the sinonasal cavities (nine cases; 82%), particularly the ethmoidal sinus (five cases). ocular proptosis was the only ophthalmic sign in four patients (36%) whereas one patient had bilateral ocular proptosis as the only sign of disease. seventeen orbits were involved due to six patients had bilateral tumor extension into the orbits. tumor extension into the orbits was mainly through the orbital bone (16 orbits; 94%). there was involvement of all compartments in most of the orbits (59%). the tumor was extraconal in 16 orbits. computed tomography revealed ocular proptosis in 15 of the 17 orbits (88%), which was bilateral in four cases (eight orbits). grade 2 ocular proptosis was observed in seven patients (47%). forty-four regions of the face and skull were involved, excluding the orbits and the primary site of the tumor, indicating extensive loco-regional disease at the time of the diagnosis.

Abstract: malignant tumors of the sinonasal cavities are rare and often diagnosed late in the course of the disease. these tumors can extend into regions such as the orbit and brain, where treatment is difficult. ten patients with nontreated sinonasal malignant neoplasms and radiological evidence of tumor extension into the orbit and brain were studied with computed tomography. five (50%) tumors were epithelial neoplasms whereas squamous cell carcinoma was the most common type (3 cases). the ethmoidal sinus was the most common site of origin of the tumors (40%), followed by the maxillary sinus (30%) and nasal cavity (30%). a total of 16 orbits were involved since 6 patients (60%) had bilateral orbital involvement. the tumors extended more often into the orbits through erosion of the medial and inferior orbital bones. all orbital compartments were involved in the majority of the orbits. tumoral extension into the cranial cavity was more common through the ethmoidal (70%) and orbital roof (30%). the anterior cranial fossa was involved in 8 cases (80%), followed by the medial cranial fossa (40%) and frontal lobe (excluding the anterior fossa) (30%). thirty-seven regions of the face, other that the site of tumor origin, orbits and cranial cavity, were involved by the 10 tumors, indicating the extensive loco-regional disease at the time of diagnosis.

Abstract: OBJETIVO: Correlacionar as complica es oftálmicas, presentes em pacientes portadores de tumores malignos extra-orbitários, com o sítio de origem e diagnóstico histopatológico destas neoplasias, por meio de tomografia computadorizada. MéTODOS: Foram estudados retrospectivamente, por tomografia computadorizada, 29 pacientes com neoplasias malignas extra-orbitárias, sem qualquer tratamento prévio do tumor, e evidência clínico-radiológica de comprometimento orbitário associado. RESULTADOS: Houve predomínio do carcinoma epidermóide (28%), seguido pelo carcinoma basocelular (14%). As complica es oftálmicas mais comumente observadas foram proptose (38%), epífora (24%) e dor ocular (24%). Redu o da acuidade visual foi referida em 14 % dos casos. Os sítios de origem mais comuns das neoplasias foram o seio maxilar (28%), o seio etmoidal (17%) e a pele e subcutaneo da face (17%). Proptose ocular foi causada predominantemente por tumores n o carcinomatosos e tumores originados no seio etmoidal, ao passo que epífora ocorreu preferencialmente nos casos de tumores carcinomatosos e de neoplasias do seio maxilar. Redu o da motilidade ocular, irrita o ocular e secre o no olho foram as complica es oftálmicas mais freqüentes em pacientes com tumores dos anexos oculares, ao passo que dor ocular foi a complica o oftálmica dominante nos pacientes com neoplasias originadas na pele e subcutaneo da face. CONCLUS ES: Os autores sugerem que, diante de paciente com epífora e massa maxilo-nasal, carcinoma do seio maxilar deve ser considerado primariamente no diagnóstico diferencial da les o. Da mesma forma, tumores n o carcinomatosos, como sarcomas e linfomas, devem ser considerados, sobretudo no diagnóstico de pacientes com proptose e massa naso-etmoidal.

Abstract: Tumores malignos das cavidades sinonasais s o raros e freqüentemente diagnosticados em estágio avan ado da doen a. A extens o destes tumores para locais críticos como a órbita e o cranio gera dificuldades no tratamento destas les es. Dez pacientes com neoplasia maligna sinonasal, sem qualquer tratamento prévio e com evidência radiológica de extens o órbito-craniana, foram estudados por tomografia computadorizada. Dos dez tumores, cinco (50%) foram neoplasias epiteliais, tendo sido a mais comum o carcinoma epidermóide (três casos). O sítio de origem tumoral mais comum foi o seio etmoidal, em quatro pacientes (40%), seguido pelo seio maxilar (30%) e pela fossa nasal (30%). Dezesseis órbitas foram comprometidas, já que seis pacientes (60%) apresentaram acometimento orbitário tumoral bilateral. Os tumores se estenderam mais freqüentemente para as órbitas através de eros o da parede medial e do soalho orbitários. A maioria das órbitas teve todos os compartimentos acometidos. Extens o dos tumores para a cavidade craniana foi mais comum através do teto etmoidal (70%) e teto orbitário (30%). A fossa craniana anterior foi acometida em oito casos (80%), seguida pela fossa craniana média (40%) e pelo lobo frontal (excluindo-se a fossa anterior) (30%). Trinta e sete regi es da face foram acometidas pelos dez tumores, excluindo-se o sítio de origem da neoplasia e a regi o órbito-craniana, corroborando a grande extens o loco-regional do tumor no momento do diagnóstico.

Abstract: Doen as sistêmicas, doen as orbitárias primárias e les es extra-orbitárias com extens o secundária para a órbita podem causar proptose ocular. Foram estudados, por tomografia computadorizada, 11 pacientes com proptose ocular causada por tumores malignos extra-orbitários, sem qualquer tratamento prévio do tumor. Houve predomínio de neoplasias n o-epiteliais (82%), tendo sido três rabdomiossarcomas (27%) e três linfomas n o-Hodgkin (27%). Outros sarcomas estiveram presentes em dois casos (18%), seguidos por linfoma de Burkitt (9%), carcinoma epidermóide (9%) e carcinoma pouco diferenciado (9%). Nove tumores (82%) tiveram origem nas cavidades sinonasais, a maioria (cinco casos) com origem no seio etmoidal. Proptose ocular foi a única altera o oftálmica em quatro casos (36%), e um paciente teve proptose ocular bilateral como único sinal da doen a. Dezessete órbitas foram acometidas pelos 11 tumores, já que seis pacientes tiveram comprometimento orbitário tumoral bilateral. Os tumores se estenderam às órbitas preferencialmente através da parede óssea orbitária (16 órbitas; 94%). Das 17 órbitas comprometidas, a maioria (59%) teve todos os compartimentos lesados. Em 16 órbitas o tumor apresentou situa o extraconal. à tomografia computadorizada, proptose ocular esteve presente em 15 das 17 órbitas (88%), tendo sido bilateral em quatro casos (oito órbitas). Houve predomínio de proptose ocular grau 2 à tomografia computadorizada (sete pacientes; 47%). Um total de 44 regi es cranio-faciais foi comprometido, além da órbita e do sítio de origem da neoplasia, indicando a grande extens o loco-regional desses tumores no momento do diagnóstico.

Abstract: a 26-year-old patient with a voluminous primary pulmonary hemangiopericytoma in the right lung, diagnosed through previous surgical biopsy, presented irreversible cardiac arrest during the hilar dissection portion of a right pneumonectomy. the patient did not respond to resuscitation efforts. autopsy showed total obstruction of the mitral valve by a tumor embolism. in cases of large lung masses with hilar involvement, as in the case presented, we recommend preoperative evaluation using transesophageal echocardiography, magnetic resonance imaging or angiotomography. if injury to the pulmonary vessels or atrial cavities is detected, surgery with extracorporeal circulation should be arranged in order to allow resection of the intravascular or cardiac mass, together with pulmonary resection. we recommend that care be taken in order to recognize and treat this problem in patients not receiving a preoperative diagnosis.

Abstract: Objective: The effects of hindlimb unweighting by tail suspension on mice’s soleus muscle cross-sectional area (CSA) and myonuclei content were studied. Methods: Five groups of male Charles River CD 1 mice (n=10 per group) were assigned to varying hindlimb suspension (HS) periods: control (cont), 1 (1HS), 2 (2HS), 3 (3HS) and 8 (8HS) days. Immediately after the suspension period, the soleus muscles were removed in order to assess morphometry data. The CSA and number of myonuclei were determined in a total of 5011 fibers (1098, 793, 1363, 1281, 1276 fibers for the cont, 1HS, 2HS, 3HS, 8HS groups, respectively) from different areas in the mid-portion region of the soleus muscle, and the CSA per myonucleus ratio was calculated. Results: The results showed that the removing of weight bearing had a negative impact on muscle fiber CSA (1686 ± 516 μm2, 1506 ± 470 μm2, 1235 ± 340 μm2, 1277 ± 412 μm2 and 1075 ± 356 μm2 in the cont, 1HS, 2HS, 3HS and 8HS groups, respectively) and myonuclei number per fiber (1.91 ± 1.17, 1.94 ± 1.30, 1.55 ± 1.01, 1.48 ± 1.00 and 0.83 ± 0.76 in the cont, 1HS, 2HS, 3HS and 8HS groups, respectively). The CSA per myonucleus ratio was 993±522μm2,854±443μm2,815±374μm2,881±442μm2 and957±367μm2 inthecont, 1HS, 2HS, 3HS and 8HS groups, respectively. Thus, there were no significant differences between the control and 8HS groups. Conclusion: The morphological data is consistent with the hypothesis that, despite the muscle fiber atrophy induced by HS, the CSA per myonucleus ratio is apparently maintained, reinforcing the concept of myonuclear domain.
