Sixty-two patients with hyperparathyroidism and failed prior neck surgery were examined by ultrasound before reoperation to localise abnormally enlarged glands. If mediastinal lesions are excluded, a total of 57 glands greater than 5 mm in size were removed from 48 patients. Ultrasound demonstrated only 18 of these for a true positive rate of 32%.

A case is presented of a 2 cm. renal angiomyolipoma. Computerized tomography demonstrated a region of low attenuation coefficient within this tumor, while B-mode ultrasound visualizes the tumor as a cluster of high amplitude echoes. The diagnosis of a renal angiomylipoma may be suspected preoperatively when this combination of findings is present with(More)
We previously reported a male patient with an 18q21.3 deletion, hyperuricemia and typical symptoms of the Lesch-Nyhan syndrome who lacked hypoxanthine-guanine-phosphoribosyl-transferase (HGPRT) deficiency. The patient developed progressive peripheral neuropathy in additon to his profound mental retardation and self-injurious behavior. At the age of 23 years(More)
The aim of the study was to compare clinical target volumes defined by CT and MRI for 3 dimensional conformal external beam radiotherapy of prostate cancer. CT and T2-weighed MRI images with 3 mm slice thickness were acquired for 13 patients with clinically organ-confined prostate cancer. Target volumes were contoured by two clinicians ("AP" and "SZ")(More)
The purpose of the study was a preliminary evaluation of the efficacy of preoperative intracavitary high-dose-rate brachytherapy (HDR BT) in sterilization of the specimen of operable cervical cancer patients enrolled into a prospective, randomized study. Between 2005 and 2010, 100 operable cervical cancer patients of FIGO stage I/A2 (n=4), I/B1 (n=51), I/B2(More)
The aim of our study was to evaluate the diagnostic performance of magnetic resonance imaging (MRI) in the pretreatment evaluation of myometrium invasion in endometrial cancer. Our retrospective study concerns 89 patients with endometrial cancer, who had preoperative MR evaluation of myometrium invasion and we compared it with histological results.(More)
Endometrial cancer of young (less then 40 years old) patients comprises 4-5% of all endometrial cancers in Hungary. The majority of patients did not give birth yet, so fertility sparing is very important. Fertility sparing treatment is possible if the tumor's histology is endometrial type and Grade 1 (well differentiated). The tumor localizes only to the(More)
OBJECTIVE To assess the clinical efficacy and safety of the combined alpha1- and postsynaptic alpha2-blocker GYKI-16084 compared to placebo during a 28-day active treatment of patients with benign prostatic hyperplasia (BPH). PATIENTS AND METHODS After a 28-day placebo run-in phase, 7.5 and 15 mg GYKI-16084 or placebo were administered twice daily for 28(More)
