Review of recent placebo-controlled trials utilizing phytotherapeutic agents for treatment of BPH.

BACKGROUND: In order to assess the efficacy of phytotherapeutic agents for the treatment of benign prostatic hyperplasia (BPH), a review of recently published double-blind placebo-controlled trials was undertaken. METHODS: Only those studies reviewed by the Other Medical Therapies Committee of the Fourth International Consultation on BPH were included. RESULTS: These studies suggest a possible benefit for the use of phytotherapeutic preparations in the treatment of BPH. CONCLUSIONS: These studies need to be confirmed in larger long-term placebo-controlled studies in order to ascertain the true efficacy of these agents.

Long-term survival in an adult metastatic renal peripheral primitive neuroectodermal tumor (PPNET) with multimodality treatment including high-dose chemotherapy.

We describe a 42-year-old male patient with a primitive peripheral neuroectodermal tumor (PPNET) arising from the kidney. The patient was treated sequentially with surgery, radiotherapy, experimental cytokine treatment (rhIL-6), combination chemotherapy and consolidated in complete remission with high-dose chemotherapy, supported by autologous stem cells (AST) and hematopoietic growth factors. The patient remains in complete remission at 34+ months after AST and is surviving disease-free for five years after initial presentation. The case presented here is unusual because of the renal origin and the long remission duration and survival when compared with the usual outcome of adult metastatic PPNET. High-dose chemotherapy may have favorably influenced the outcome in this patient. The case is discussed in the context of the general treatment of metastatic PPNET.

Endoscopic submucosal Teflon injection (STING): an alternative treatment of vesicoureteric reflux in children.

The authors present their results in treating vesicoureteric reflux with an endoscopic submucosal teflon injection (STING) of the refluxing ureter. One hundred refluxing units in 68 children were treated with a maximum follow-up of five years. Indications were high grade reflux (III-V), persistence or progression of reflux despite conservative therapy, breakthrough urinary infections despite antibiotic prophylaxis and finally bad antibiotic compliance. Treatment was performed on an outpatient basis and appeared to be free of complications. Reflux was cured with a success rate of 75% after a single injection and 96% after two injections. With respect to the grade of reflux, best results were obtained in low grade reflux (Grade I-II). A 60-70% success rate was obtained in high grade reflux (III-V). The main advantage over open reimplantations lies in its non invasiveness, simplicity and possibility of being repeated in case of failure.

Laparoscopy: any indication in the work-up and treatment of undescended testis?

About 10% of undescended testis are non palpable. Surgical exploration of the inguinal region was the standard treatment, mainly because reliable "localisation tests" were not available. Today, laparoscopy is becoming the first step for optimal management of this problem. This technique combines relevant diagnostic information with therapeutic facilitations.

Endocrine profiles during administration of the new non-steroidal anti-androgen Casodex in prostate cancer.

OBJECTIVE: Casodex (Zeneca) is a new potent, long-acting non-steroidal anti-androgen, which produces androgen deprivation by blocking the androgen receptor. We evaluated the endocrine effects of Casodex 150 mg daily given in monotherapy as primary treatment for patients with prostate cancer. DESIGN: As part of a large, multicentre study comparing the therapeutic effects of surgical castration with 150 mg/day Casodex in monotherapy for patients with prostate cancer, a subgroup of 23 patients on Casodex were studied in detail for changes in endocrine parameters. Serum levels of LH, FSH, testosterone, DHT, oestradiol, prolactin, sex hormone binding globulin and free testosterone were measured at the start of therapy and after 1, 4, 8, 12 and 24 weeks. Effects on libido, sexual activity and the appearance of hot flushes, breast pain and gynaecomastia were recorded. RESULTS: Administration of Casodex resulted in a rise in LH levels in all patients with a mean increase after 24 weeks of 102% (P < 0.001). Mean FSH levels showed a limited increase (7%) after 24 weeks, which was significant only after 1 week (P < 0.001). As a result of the high LH levels, total testosterone levels increased after 24 weeks by 66% (P < 0.001), free testosterone by 57% (P < 0.001) and dihydrotestosterone by 24% (P = 0.0112). Parallel to testosterone, oestradiol levels rose by a mean of 66% (P < 0.001). Mean sex hormone binding globulin and prolactin levels rose by respectively 8% (P = NS) and 65% (P < 0.01). Despite an increase in testosterone levels, excellent androgen blockade was obtained, as shown by a decrease in prostate specific antigen levels in 22/23 patients. Libido was maintained in 8/11 patients, and sexual activity in 5/6. No patient complained of hot flushes. However, mild gynaecomastia and/or breast tenderness were seen in 48 and 30% of cases respectively. CONCLUSION: Casodex 150 mg/day monotherapy resembles surgical castration in achieving androgen deprivation, despite an increase in LH and testosterone levels. In contrast to castration, libido and sexual activity are usually maintained and hot flushes are rare. However, mild gynaecomastia and/or breast tenderness were noted in 48 and 30% of patients.

[Technetium 99m labeled dimercaptosuccinic acid (99m Tc-DMSA) scintigraphy in the diagnosis and follow-up of urinary infections in children].

BACKGROUND: The site of a urinary tract infection (UTI) is located by clinical findings plus imaging techniques. Renal imaging with technetium 99mTc-dimercaptosuccinic acid (99mTc-DMSA) has shown promise but its efficacy for detecting acute pyelonephritis is still debated as is its ability to differentiate between acute, potentially curable disease and scarring, definitive changes. PATIENTS AND METHODS: The files of all the 166 patients that underwent one or two (32 patients) 99mTc-DMSA imaging sessions for UTI in 1989 and 1990 in our department were analysed. The results of this technique were compared with the clinical and laboratory data and with those of other imaging techniques (ultrasonography and retrograde voiding cystourethrogram). The patients (92 girls and 74 boys, mean age: 5 years, range 15 days-17 years) were assigned to one of 3 categories: 1) acute pyelonephritis (27 patients), 2) low UTI (60 patients) and 3) uncertain UTI (79 patients), on the basis of the clinical and laboratory data. RESULTS: The first 99mTc-DMSA imaging was normal in 110 children; changes were unilateral in 45 and bilateral in 11 children. Images suggesting either acute or chronic changes were observed respectively in 19 and 48 children. 4 of the 7 acute changes were normalized on the second radioisotope scanning while 2 became worse; 19 of the 23 chronic changes were unchanged at the second scanning. Radioisotope scanning changes were seen in 81% of the patients classified as acute pyelonephritis and in only 27% of those with lower UTI. Reflux was detected in 56% of abnormal kidneys and in 36% of normal kidneys. The results of radioisotope scanning and ultrasound scan findings were not correlated in 24 patients (19 only abnormal radioisotope imaging, 5 only abnormal ultrasound scan). CONCLUSIONS: DMSA scans are useful for investigating and following UTI. They help to distinguish acute pyelonephritis and lower UTI. It is a reliable method of detecting structural abnormalities and identifying children at risk of progressive renal damage.

The use of prostaglandins for diagnosis and treatment of erectile impotence.

The authors present their experience in using PGE-1 for the assessment of 77 impotent patients. This drug can be safely used as a screening test for vasculogenic impotence but is also useful in more invasive diagnostic tests. PGE-1 is probably the only natural product that can be used commonly for the treatment of erectile impotence, because it is a safe and effective drug.

Ultrasonically guided prostatic biopsy: technical improvements.

Combining the use of a longitudinal real-time transrectal ultrasound scanner (Bruel & Kjaer 8537 7 MHz Sector Scan), an attachable puncture guide (Bruel & Kjaer UA 0875) and the Biopty-Cut apparatus (Radioplast), one can now easily perform all prostatic biopsies with ultrasonic guidance. We evaluated this method in 75 patients and found it to be a most elegant and accurate method for the histological diagnosis of prostate cancer.

[Echographic anatomy of the male urethra].

Sonographic urethrography is used as a new tool in understanding urethral pathology. Although a prospective study is necessary to demonstrate it, this examination seems to be complementary to retrograde Urethrography.
