BACKGROUND The late descent of a testicle into the scrotum may impair its development. Reduced fertility is the main risk of primary cryptorchidism even after timely treatment, as histopathological changes (Leydig cell hypoplasia) already become apparent in the first few months of life. There is evidence, however, that treatment is often delayed. Hormonal(More)
We reviewed the results of arthroscopic lateral release using electrosurgery in 39 patients (45 knees) with a history of recurrent patellar subluxation or dislocation. The average follow-up time was 28 months (range, 24-36). At follow-up, the patients had decreased swelling, instability, and pain. There was an improvement in flexion activities, sports(More)
Recent reports of the impact of estrogen receptor alpha and aromatase deficiency have shed new light on the importance of estrogen for bone formation in man. We describe a novel mutation of the CYP19 gene in a 27-yr-old homozygous male of consanguinous parents. A C to A substitution in intron V, at position -3 of the splicing acceptor site before exon VI of(More)
OBJECTIVES To examine a potential association between the response to the phosphodiesterase-5 inhibitor sildenafil and angiotensin-converting enzyme (ACE), as well as NOS3 G894T genotypes in patients with erectile dysfunction (ED). An insertion/deletion (I/D) polymorphism in the gene encoding the ACE and a single nucleotide exchange polymorphism (G894T) in(More)
Erectile dysfunction (ED) is often associated with cardiovascular disorders such as hypertension, coronary heart disease, hypercholesterolaemia and diabetes mellitus. The genotypes in the GNB3 C825T, the ACE I/D and the eNOS G894T polymorphisms have been identified as genetic risk factors for cardiovascular disorders. The association between the genotypes(More)
Titanocene dichloride was capable of inhibiting the growth of different types of human tumors in vitro. A total of 14 patients with metastatic renal-cell carcinoma (RCC) received 270 mg/m2 titanocene dichloride every 3 weeks for 6 weeks. Although the toxicities and side effects encountered were mild to moderate, no partial or complete response was(More)
PURPOSE Sildenafil is the oral phosphodiesterase-5 inhibitor that revolutionized treatment for erectile dysfunction. We investigated a potential association of the G protein beta 3 subunit (GNB3) C825T polymorphism, a determinant of intracellular signal transduction, with the drug response to sildenafil in patients with erectile dysfunction. MATERIALS AND(More)
A patient with Cronkhite-Canada syndrome had multiple juvenile colonic polyps with hyperplastic, adenomatous, and mixed villous and adenomatous changes. A Dukes B mucus-secreting adenocarcinoma of the cecum was also present. Currently considered a benign disease, the Cronkhite-Canada syndrome may be a premalignant disorder, as our patient's course suggests.(More)
OBJECTIVE To determine the affinities of human penile alpha-adrenoceptors and cloned human alpha-adrenoceptor subtypes for trazodone, an antidepressant with reported beneficial effects in erectile dysfunction. Materials and methods Competition radioligand binding studies were performed with trazodone in human penile tissue and in cell lines stably(More)
OBJECTIVES Young men often complain about problems with condom use, but very little information exists about the influence of men's age on penile dimensions and therefore on possible problems in the use of the most important means of contraception in the young. METHODS We performed a prospective measurement of penile dimensions in 111 men,18 to 19 years(More)
