Double lumen dissecting aneurysms of the internal carotid artery in fibromuscular dysplasia: case report.

A young man with cerebral infarction, skeletal, cardiac and renal malformations was found to have on angiography a rare lesion involving the cervical left internal carotid artery, formed by the superposition of two arterial lumina. Anti-platelet therapy did not prevent thrombosis of the lesion and reinfarction. Extracranial-intracranial bypass graft was performed, followed by excision of the arterial lesion. Pathological examination revealed fibromuscular dysplasia and dissecting aneurysm. The few reported cases associating fibromuscular dysplasia of the internal carotid artery with dissecting aneurysm are reviewed. Surgical therapy is recommended in such cases when symptomatology progresses. Fibromuscular dysplasia occasionally coexists with somatic malformations, suggesting a congenital origin of this condition.

Long-term evaluation of venous tissue in the construction of cardiac valves.

We present the evolution of venous tissue, used as a mitral or tricuspid prosthesis or in the reconstruction of the right ventricular outlet tract, for periods of up to 18 months. A histological and hydrodynamic study is made of the valves after sacrificing the animals. The venous tissue showed fibrosis, structural disorganization, elastosis, elastorexis and, above all, intense calcification in heavy deposits. Since the venous tissue evolved toward fibrosis and calcification, its use is considered contraindicated.

[First radiological description of Morgagni's hydatid. Laparoscopic confirmation].

The authors explain the clinical case of a female patient suffering from secondary sterility; she was submitted, among other test, to the H.S.G. in order to study the possibility of a among other tests, to the H.S.G. in order to study the possibility of a cervical failure. The radiological findings obtained of Morgagni's Hydatis, not described previously in literature and their laparoscopic confirmation justify, we believe, its publication.

Will patient satisfaction set the preventive services implementation agenda?

BACKGROUND: Patient satisfaction has become a measure of the quality of health care, and in highly competitive markets like the Twin Cities metropolitan area of Minnesota, it has become a health plan marketing tool. The purpose of this analysis is to examine whether the known association between preventive services and patient satisfaction might spontaneously lead clinicians to recommend preventive services at greater rates. DESIGN: We conducted a mail survey of a stratified random sample (n = 6,830) of adult patients who had recently visited a physician in one of 44 clinics in and around Minneapolis-St. Paul, Minnesota. The main outcome measures are patient-reported rates of being advised to have eight preventive services, patient satisfaction with preventive services, patient satisfaction with overall health care, and correlations among these variables. RESULTS: Self-reports of being advised to have a preventive service when due were correlated with higher levels of satisfaction with that specific service only at levels of r = 0.16 to r = 0.35. They were correlated at levels of r = 0.01 to r = 0.27 with the Group Health Association of America satisfaction index. CONCLUSIONS: Although there is a positive association between being advised to have a preventive service on the one hand and reporting satisfaction with care on the other, this association appears too weak to spontaneously stimulate physicians to recommend preventive services to their patients. This suggests that, if preventive services are to be delivered at higher rates, they must become an explicit component of quality evaluations.
