At the Surgery Clinic of the Endocrinology Institute in Lódź we operated 12 344 patients between 1974 and 1992 because of various types of goitre. Among these there were 295 children and adolescents, 2.4%- aged between 9-18 years: 268 girls (90.8%) and 27 boys (9.2%). The goitre was 9.9 times more frequent in girls than in boys. In adults the ratio was 8:1.
The purpose of the presented study was the assessment of diagnostic and therapeutic efficacy of percutaneous drainage of pancreatic pseudocysts and abscesses, guided by ultrasound (US). The study population comprised 65 patients, aged 21-79 years: in 18 of them pancreatic abscess and in remaining 47--pancreatic pseudocyst were diagnosed. Causes of the fluid accumulation were: acute pancreatitis--in 57, trauma--in 3 and in 5 the specific etiological factor was not found. Ultrasound was performed with Aloka Hellige SSD 280-LS scanner and Braun Melsungen Nephrofix and Cystofix kits were used for drainage. Enzymatic, bacteriologic and cytologic examination of aspirate was performed. Duration of catheter drainage in pseudocysts was 10-40 days (mean 18) and from abscesses--21-56 days (mean 32). A variety of organisms was cultured from pancreatic fluid, Escherichia coli being most prevalent, also Proteus, Staphylococcus, aureus etc were found. Definite cure was obtained in 54 (83%) patients, among them in 40 (85.1%) with pseudocysts and in 14 (77.7%) with abscesses, which was confirmed in control imaging examinations (US and/or CT) after 4-6 months after catheter was removed. In 10 (15.38%) cases surgical intervention appeared necessary--in 7 patients during unsuccessful drainage and in 3--because of late recurrence. One patient died after relaparotomy. Percutaneous drainage is effective in the treatment of pancreatic fluid collections, allowing in most cases avoiding surgical intervention and providing additional diagnostic data.

Cyclic AMP concentrations in a non-toxic nodular goiter were measured by means of the radiocompetitive protein-binding assay. It has been shown that cold thyroid nodules contain a higher concentration of cAMP than the macroscopically normal, extra-nodular thyroid tissue.
