Abstract: A persistência da veia cava superior esquerda com ausência da veia cava superior direita é uma anomalia rara, com menos de 150 casos descritos na literatura. A n o-oblitera o e regress o da veia cardinal anterior esquerda durante o desenvolvimento embriológico promove uma varia o sistêmica de retorno venoso ao cora o, com persistência da veia cava superior esquerda. Sua incidência varia de 0,3% em pacientes sem altera es cardíacas congênitas concomitantes a 4,3% naqueles com cardiopatias. Na maioria das vezes coexiste a veia cava superior direita, porém se houver regress o e degenera o da veia cardinal anterior direita, implicará a sua ausência e a drenagem venosa para o cora o será feita pela veia cava superior esquerda ao átrio direito, através do seio coronariano. Mostramos um caso de um paciente submetido a radiografia de tórax e tomografia computadorizada para avalia o de doen a pulmonar obstrutiva cr nica, tendo como achado a persistência da veia cava superior esquerda com ausência da direita, sem qualquer cardiopatia associada e com a drenagem cardíaca sendo feita, através do seio coronariano, para o átrio direito.

Abstract: fibrodysplasia ossificans progressiva is a rare hereditary connective tissue disease characterized by disseminated soft tissue ossification and congenital abnormality of the extremities. it is genetically inherited as a dominant trait with complete penetrance but variable expression. the onset takes place during childhood and the progressive involvement of the spine and proximal extremities leads to immobilization and articular deformity. we report a case of a 22-year-old male patient with typical symptoms of fibrodysplasia ossificans progressiva and discuss the new advances in the diagnosis and pathophysiology.

Abstract: purpose: to evaluate macroscopically the growth degree of self-transplantation of endometriosis in rats. methods: forty female rats, after a 7-day period for adpating and evaluating of the estrous cycle regularity, underwent tail abdominal midline laparotomy with 3-cm cuts. the average third of the left uterine horn was removed, 4mm x 4mm patches in liquid environment were made, and self-transplanted in the rat mesenterium with a single stitch, and the endometrial surface of the endometriotic implant facing the lumen of the peritoneal cavity. the rats were programmed to die after three weeks. the abdominal cavity displaying was held and self-transplants were identified and classified. results: the results achieved were: one case for degree 0 (2,5%), three cases for degree 1 (7,5%), eleven cases for degree ii (27,5%) and twenty-five cases for degree iii (62,5%). conclusion: the experimental endometriosis development, through the self-transplantation technique, showed to be most common in degrees 3 and 2 of development.

Abstract: purpose: to analyze the macroscopic and histological changes that occur with the use of sinvastatin in experimental endometriosis in female rats. methods: forty wistar female rats were submitted to the technique of uterine self-transplant in mesenterium. after three weeks, 24 of them developed experimental endometriosis grade iii, and were divided in two groups: one group received sinvastatin orally (20 mg/kg/day) and the other (control group) received 0.9% of sodium chloride orally (1 ml/100 g of body weight/day). both groups received gavage for 14 days, followed by death. the implant volume was calculated [4p (lenght/2) x (width/2) x (height/2)/3] at the surgical intervention and after the animal?s death. the self-transplants were removed, dyed with hematoxylin-eosin and analyzed by light microscopy. the mann-whitney?s test was used in the independent samples and the wilcoxon?s test for the related samples. the fisher?s exact test was used for the histological evaluation, with a significance level of 5%. results: the difference between groups of the initial average volumes of the self-transplants was not significant (p=1.00), but became significant for the final average volumes (p=0.04). there was a significant increase (p=0.01) between the initial and final average volumes in the control group, and a no significant decrease in the sinvastatin group (p=0.95). histologically, the sinvastatin group (n=9) presented seven cases (77.8%) of moderately preserved and two cases (22.2%) of well preserved epithelial wall, while the control group (n=12) presented seven cases (58.3%) of moderately preserved and five cases (41.7%) of well preserved epithelial wall. conclusions: sinvastatin prevented the growth of experimental endometriosis. studies with sinvastatin for longer periods are promising.

Abstract: persistent left superior vena cava with absent right superior vena cava is a rare anomaly, with less than 150 cases reported in the literature. congenitally persistent left superior vena cava is the most common variant of systemic venous return to the heart, resulting embryologically from failure of the left anterior cardinal vein to become obliterated. its incidence varies from 0.3% in patients with otherwise normal heart to 4.3% in patients with congenital heart disease. in the majority of the patients, a right superior vena cava is present as well, but rarely the right anterior cardinal vein degenerates resulting in the absence of the normal right superior vena cava. the blood from the right side is carried by the persistent left superior vena cava to the right atrium through the coronary sinus. we report the case of a patient with a persistent left superior vena cava and absence of right superior vena cava identified by chance during a chest radiograph and computed tomography examination for investigation of chronic pulmonary obstructive disease. the patient had no congenital heart disease and the blood from the right side was drained by the persistent left superior vena cava into the right atrium through the coronary sinus.
Manifesta??es extrapulmonares da paracoccidioidomicose
Costa, Marlos Augusto Bitencourt;Carvalho, Tarcísio Nunes;Araújo Júnior, Cyrillo Rodrigues de;Borba, Ana Olívia Cardoso;Veloso, Gerson Augusto;Teixeira, Kim-Ir-Sen Santos;
Radiologia Brasileira , 2005, DOI: 10.1590/S0100-39842005000100010
Abstract: the authors present a review and iconographic study of patients with disseminated paracoccidioidomycosis, including the main radiographic findings seen in the central nervous system, adrenal glands, osteoarticular system, lymph nodes and digestive tract. imaging diagnostic methods have allowed a more precise approach of these patients due to their high sensitivity in detecting lesions, even in asymptomatic patients. in most cases these abnormalities are unspecific, simulating either neoplasic or chronic infectious lesions, and sometimes difficult to distinguish from tuberculosis. although these findings are nonspecific and only the mycologic and histologic fungus demonstration can confirm the diagnosis, they may suggest a presumptive one, when these imaging findings are considered in an appropriate clinical and epidemiological setting.
