[Rates of prostate-specific antigen testing for early detection of prostate cancer: a first comparison of German results with current international data]

OBJECTIVE

Measurement of prostate-specific antigen (PSA) is not only used as a screening instrument by urologists, but also by general practitioners and internal specialists (GP-IS). Until now, there are neither data on the approach of German GP-IS in practicing this nor have data been classified in the context of available international literature on this topic.

MATERIALS AND METHODS

Between May and December 2012, a questionnaire containing 16 items was sent to 600 GP-IS in Brandenburg and Berlin. The response rate was 65% (392/600). Six indicator questions (IQ1-6) were selected and results were set in the context of available international data. The quality of present studies was evaluated by the Harden criteria.

RESULTS

Of the 392 responding physicians, 317 (81%) declared that they would use PSA testing for early detection of PCA (IQ1) and, thus, formed the study group. Of these GP-IS, 38% consider an age between 41 and 50 years as suitable for testing begin (IQ2), while 53% and 14% of the GP-IS perform early detection until the age of 80 and 90 years, respectively (IQ3). A rigid PSA cut-off of 4 ng/ml is considered to be reasonable by 47% of the involved GP-IS, whereas 16% prefer an age-adjusted PSA cut-off (IQ4). Patients with pathological PSA levels were immediately referred to a board-certified urologist by 69% of the GP-IS. On the other hand, 10% first would independently control elevated PSA levels themselves after 3-12 months (IQ5). Furthermore, 14% of the interviewed physicians consider a decrease of PCA-specific mortality by PSA screening as being proven (IQ6). Knowledge regarding PCA diagnostics is mainly based on continuous medical education for GP-IS (33%), personal contact with urologists (6%), and guideline studies (4%). While 53% indicated more than one education source, 4% did not obtain any PCA-specific training. The results provided by this questionnaire evaluating response of German GP-IS to six selected indicator questions fit well into the international context; however, further studies with sufficient methodical quality are required.

CONCLUSIONS

Despite current findings and controversial recommendations of the two large PCA screening studies on this issue, German GP-IS still frequently use PCA screening by PSA measurement. Primary strategies of early detection as well as follow-up after assessment of pathologically elevated PSA levels poorly follow international recommendations. Thus, an intensification of specific education is justified.

[Penile injury caused by a Moulinette. Result of autoerotic self-mutilation]

Autoerotic manipulations of external male genitals resulting in mutilation with different degrees of severity are rare. We report the clinical case of a 12-year-old boy who injured his glans, left corpus cavernosum and corpus spongiosum with opened urethra as a consequence of autoerotic genital self-mutilation. According to our knowledge of the current literature this is the first description of autoerotic genital self-mutilation with a Moulinette. A Moulinette is a kitchen tool with an electric engine and an extremely fast rotary double knife, which is used to reduce food into small pieces, especially vegetables and fruits.

Adenomatoidtumor des Hodens – eine seltene Entität

Adenomatoid tumor with intra-testicular localization is rare. Although most reported cases arise from the epididymis, rare cases have been reported in the testicular tunica, spermatic cord, ejaculatory ducts, prostate and suprarenal recess. Adenomatoid tumors occur in both sexes and are also found in the uterus, ovary and fallopian tubes of the female genital tract. Adenomatoid tumors are benign proliferations of mesothelial origin. We report the case of a 50-year-old male with an adenomatoid tumor of the left testis. Because of its rarity, the clinical, diagnostic and therapeutic aspects as well as the possibilities of testicular preservation are discussed.

Harnblasenscheidenfistel nach Implantation eines Harnleiterthermostents bei radiogener langstreckiger prävesikaler Harnleiterstenose

The implantation of ureteric thermo-stents in the treatment of benign and malignant ureteric strictures is, besides ureterocystoneostomy, replacement of the ureter by intestine, double-J catheter, and nephrostomy, an alternative therapeutic option. We report on a female patient with a radiological long segment stricture of the left lower ureter who developed a fistula between the bladder and vagina 6 months after implantation of a ureter thermo-stent because the distal end of the thermo-stent extended into the bladder.
