Over a period of 42 years, 581 patients with presumed hyperparathyroidism underwent an initial cervical exploration. Abnormal parathyroid glands were removed from 495 patients (85.2%). There was a greater probability of operative success in women, patients over 50 years of age, and patients with hypercalcemia, hypertension, or nonspecific abdominal pain. There was no association of operative outcome with some of the "classic" manifestations of hyperparathyroidism--peptic ulcer disease, neuropsychiatric symptoms, pancreatitis, bone disease, or urolithiasis. The probability of surgical success improved with time, increasing from 56 per cent in the 1950s to 97 per cent in the present decade. This improvement appears to be related to greater operative experience, since all four parathyroid glands were more likely to be found with increased experience, and there was a strong correlation between finding four parathyroids and achieving persistent normocalcemia. The most common causes of operative failure were inaccurate calcium assays (the patient was not truly hypercalcemic), an inappropriate diagnosis ("normocalcemic hyperparathyroidism"), and surgical inexperience. These three factors accounted for at least three fourths of all negative explorations. More accurate diagnostic studies, and careful exploration by an experienced surgeon should maximize the probability of a successful operation for primary hyperparathyroidism.

In many respects abdominal pain in pregnancy is managed just as in a nonpregnant patient, but the diagnostic criteria, methods of diagnosis, therapy, and consequences of mismanagement differ. This article discusses appendicitis, cholecystitis, urolithiasis, pancreatitis, and intestinal obstruction--conditions that often manifest a similar clinical picture. The article presents epidemiologic data, distinguishing characteristics, modifications of the workup, and treatment appropriate to pregnancy and perinatal complications of each condition.

The entire middle-aged male urban population of a Swedish city, as defined by a census in November 1969, was assessed for any mental hospital hospitalization during a 3-year period (1978-1980), as well as for any general hospital hospitalization during a 10-year period (1970-1979) within the catchment area. Inpatients of the mental hospital population belonging to the cohort and put in the categories 'Psychiatric alcoholic spectrum' and 'Severe depression' were studied for diagnoses of physical illness during any general hospital hospitalization. The psychiatric alcoholic spectrum was associated positively with infections, injuries, alcohol intoxication, pancreatitis, liver cirrhosis, arthritis/rheumatic diseases and duodenal peptic ulcer; and negatively with malignant neoplasms, myocardial infarction, gallstone disease and urolithiasis. Severe depression was associated positively with infections, myocardial infarction, asthma and alcohol intoxication. A nosologic taxonomy, aimed at explaining the epidemiological associations recorded, is suggested.

Our purpose is to describe the ultrasound sign for a correct non-invasive diagnosis of omental infarction in children. From January 2014 to December 2018, a total of 234 children (109 boys and 125 girls, age range 3-15 y) with acute right-sided abdominal pain, admitted to our hospital with a presumptive diagnosis of acute appendicitis, were prospectively evaluated. In all patients, abdominal ultrasound was performed, and the omental fat was always evaluated. In 228 patients, the omental fat resulted to be normal or hyperechogenic, never tethered, and they results affected by other causes of abdominal pain different from omental infarction (such as appendicitis, pancreatitis, urolithiasis and others). In the remaining 6 children, we found a hyperechoic mass between the anterior abdominal wall and the ascending or transverse colon in the right abdomen quadrant, suggesting the diagnosis of omental infarction. This subhepatic mass was always tethered to the abdominal wall, motionless during respiratory excursions. We named this finding the "tethered fat sign." The diagnosis was confirmed with laparoscopy in 4 children. The other 2 children were treated with conservative therapy. In these 2 patients, a sonographic follow-up was performed, showing a progressive reduction in size of the right-sided hyperechoic mass. In conclusion, our study suggests that the presence of the "tethered fat sign" may be an accurate sonographic sign for non-invasive diagnosis of omental infarction in children.

Thoracic and abdominal pathology are common in the emergency setting. Although computed tomography is preferred in many clinical situations, magnetic resonance imaging (MRI) and magnetic resonance angiography (MRA) have emerged as powerful techniques that often play a complementary role to computed tomography or may have a primary role in selected patient populations in which radiation is of specific concern or intravenous iodinated contrast is contraindicated. This review will highlight the role of MRI and MRA in the emergent imaging of thoracoabdominal pathology, specifically covering acute aortic pathology (acute aortic syndrome, aortic aneurysm, and aortitis), pulmonary embolism, gastrointestinal conditions such as appendicitis and Crohn disease, pancreatic and hepatobiliary disease (pancreatitis, choledocholithiasis, cholecystitis, and liver abscess), and genitourinary pathology (urolithiasis and pyelonephritis). In each section, we will highlight the specific role for MRI, discuss basic imaging protocols, and illustrate the MRI features of commonly encountered thoracoabdominal pathology.
