Evaluation of flow in nodular tumors of the breast by Doppler and duplex scanning.

Evaluation of flow in nodular tumors of the breast may be performed by Doppler and computerized frequency analysis. In 46 nodules of the breast (22 malignant) the nodular flow velocity and frequency analysis revealed a faster flow with a significantly higher peak frequency and mean velocity. The intensity of sound which may be considered an index of the entity of flow in the nodule was larger than that observed in the normal surrounding breast tissue. In malignant nodules and generally in fast growing nodules the flow velocity and intensity was even larger. The flow intensity and velocity was also well correlated with the growth rate as reported by single patients. In elder patients a slow rate of growth even in tumors of larger size was associated with a significantly increased flow in comparison with the normal breast tissue but this increase was not particularly large when compared with fast growing nodules in younger subjects. In conclusion the evaluation of flow characteristics (mainly velocity, frequency analysis and intensity) may be a useful index of the growth rate of nodular tumors of the breast and these data may be useful to evaluate and monitor the evolution and pathophysiology of these nodules.

[Carotid thromboendarterectomy. The authors' personal experience].

Carotid endarterectomy is the most frequently employed surgical intervention in the treatment of strokes due to atherosclerosis obstruction of the blood flow in extracranial carotid district. The presence of cerebrovascular clinical symptoms is accepted indication for surgical treatment. For the patients without symptoms there is, however, not yet a complete agreement on the treatment modalities. The authors believe that, due to the low morbidity and mortality of carotid endarterectomy, a surgical approach can be used in patients in which is present a degree of stenosis > 75% and, moreover, in patients where the degree of stenosis is > 50%, but in which the atherosclerotic plaque is non homogeneous due to the presence of ulceration or hemorrhage. Non invasive ultrasonic techniques constitute the mainstay of the diagnostic procedures for carotid artery disease and in recent years they have led to improved sensitivity and ability in differentiating between the operable carotid stenoses and the inoperable obstructions. With these techniques it is possible to arrive to a 90% diagnostic accuracy. Also the recently introduced angio-RM has comparable results, but the high costs do not make it possible to use it in screening procedures. Many doubts are present regarding the possibility of evaluating the occurrence of neurologic deficits during the surgical procedures. Local anaesthetic techniques are somewhat popular among vascular surgeons in that they allow an immediate evaluation of the neurologic activity of the patients during surgical treatment. However reports have been published in the literature of neurologic deficits arising after the period of test occlusion.

[Gynecomastia].

Gynaecomastia is a benign enlargement of the male breast commonly occurring in healthy adolescent boys and in adults (50 to 80 years old). It is a source of cosmetic and psychologic problems. The secondary forms usually require no therapy other than the removal of any identified inciting cause. Most of the idiopathic forms last only a few months and then gradually disappear. In secondary gynaecomastia and idiopathic forms present for more than 12 months a medical hormonal treatment often fails and the only therapy is surgery consisting in a subtotal subcutaneous mastectomy. In the last years the surgical treatment is often completed with suction lipectomy: this procedure reduces the surgical traumatism. The authors present their experience concerning 47 patients: 27 were surgical treated with subcutaneous subtotal mastectomy and 18 had an abjunctive liposuction treatment with good results.
