Ultrasonic diagnosis of primary carcinoma of the gallbladder: a review of 16 cases.

Sonographic findings in 16 patients (10 women, six men) with surgically documented gallbladder carcinoma are reported. Two principal forms are described: localized infiltrating, or fungating, tumors (eight patients) and diffuse tumors infiltrating the entire gallbladder wall (eight patients). In all cases, the tumors were adenocarcinomas. Eleven patients also had cholelithiasis. Contiguous extension and metastasis did not correlate with tumor size. The difficulties encountered an the differential diagnosis are discussed in relation to the different sonographic appearances.

[Ultrasonography characteristics of primary cancers of the gallbladder. A report on 16 cases (author's transl)].

Primary cancer of gallbladder was detected by ultrasonography in 16 patients (10 women, 6 men), and confirmed at operation. Two main types of lesion were found: 8 localized forms (infiltrating or vegetating), and 8 diffuse forms with infiltration of the gallbladder wall. The lesion was an adenocarcinoma in each case, and there was associated lithiasis in 11 patients. Extension by contiguity or metastases is independent of the size of the cancer. Problems related to etiological and differential diagnosis of these lesions are discussed in relation to the different ultrasonography appearances observed.

Systolic time intervals and echocardiographic findings in borderline hypertension.

Systolic time intervals, echocardiographic dimensions and hemodynamic parameters were determined in 42 borderline hypertensive patients with high cardiac output and 33 normal subjects. In borderline hypertensive patients, the preejection period was significantly reduced (P less than 0.001) and was negatively correlated to cardiac index (P less than 0.001). The interventricular septum thickness (IVS) was significantly increased (P less than 0.001) while the posterior wall thickness (PW) was within normal values. The IVS/PW ratio was significantly elevated (P less than 0.001) and was correlated negatively with the cardiac index (P less than 0.01) and positively with the preejection period (P less than 0.01). These findings suggest that (i) myocardial hypertrophy and increased left ventricular performance exist in borderline hypertension, (ii) myocardial contractility is reduced as myocardial hypertrophy increases.

[Critical study of echocardiography in mitral cardiopathies].

The importance of the echocardiogram in a study of mitral disorders has been analysed by examining 107 echocardiograms set against a clinical examination, an investigation of haemodynamic function (57), left-sided angiography (42), and/or examination at the time of operation (40). This study confirms the great diagnostic value of the echocardiographic findings in mitral stenosis (56 patients): the amplitude DE, the slope EF, the percentage of mid-diastolic closure, the echo from the valves, and the dimension of the left atria (P less than 0.001). This association remains valid if there is mitral incomptence as well as stenosis, or if there is also an aortic lesion, provided all the parameters are used. The degree of stenosis of the mitral orifice cannot be determined with sufficient certainty to allow surgical exploration to be undertaken solely on echocardiographic results, however the patients are selected (sinus rhythm, absence of calcification, mobile valve...). The echocardiographic diagnosis of the 17 cases of mitral incompetence was incomplete (except for rupture of the chords); the volume of the regurgitation is poorly appreciated.
