Detection of thymoma in myasthenia gravis.

Twenty patients with myasthenia gravis had chest radiography, conventional tomography, and computed tomography (CT) of the thorax within 1 month of thymectomy. Four of the six macroscopic tumors were detected on routine chest radiography; conventional tomography provided no additional information. CT detected all six macroscopic tumors and provided additional information that was not available by other procedures. However, 18 patients (90%) had anterior mediastinum densities on CT, which could not be distinguished preoperatively from thymic tumors. All six patients with macroscopic tumors had serum antistriational muscle antibody titers; this test was negative in 10 of 11 patients (91%) without thymoma. Chest radiography, CT of the thorax, and antistriational antibodies are the tests recommended for detection of a thymoma in patients with myasthenia gravis.

Follow-up of 2000 second-trimester amniocenteses.

The authors analyzed the outcome of 2000 consecutive second-trimester amniocenteses. Seventy-three percent were performed for maternal age of 34 years or more. The risk of spontaneous abortion before 28 weeks' gestation was 1.3% and for stillbirth or neonatal death, 1.4%. Total fetal loss was 2.7%, compared with 2.2% in a control population. Congenital malformations were found in 1.6% of the study group and in 1.9% of controls; no increase in skeletal problems was observed. Prematurity, defined as a birth weight of less than 2500 g, was noted in 3.6%, compared with 3.7% and 3.9% in 2 control populations. Respiratory difficulties persisting for more than 24 hours were observed in 0.8% of patients, compared with 0.7% of controls. Analyses of the outcome of amniocenteses performed at a single large center do not show an increase in perinatal complications or malformations.

Ultrasonic evaluation of abdominal gastrointestinal tract duplication in children.

Ultrasonographic evaluation of a suspected abdominal mass in children is becoming routine. Recognition of a rare congenital anomaly known as duplication of the gastrointestinal tract might aid in diagnosis and obviate the need for an extensive workup. Two cases are presented that clearly demonstrate the ultrasonographic spectrum of findings in this condition, ranging from a sonolucent cyst to an echogenic mass. An echogenic inner rim seen ultrasonographically is highly suggestive of the diagnosis.

Value of gallbladder B-scan ultrasonography.

The gallbladder B-scans of 20 patients who had subsequent surgery were separated into three categories based upon certain sonographic criteria. Our data, in this limited series, revealed gallbladder pathology in each patient who had any one or combination of the following scan characteristics: (1) internal echos, (2) irregular wall, or (3) absence of recognizable gallbladder sonolucency. The category which demonstrated a normal sonographic gallbladder, namely a smooth wall and no internal echos, contained a number of false negatives which proved to have either small stone cholelithiasis or extraphepatic ductal obstruction. Within the described limitations, the B-scan can be a valuable test in confirming the significance of a radiographically nonvisualized gallbladder or in detecting a biliary tract lesion in a patient with a disease entity that precludes radiographic visualization by conventional techniques.
