Evaluation of penile arterial system with color Doppler ultrasonography in nondiabetic and diabetic males.

The parameters of the functional evaluation of the penile arterial system in sexually active males are based on a minimal number of volunteers and impotent patients of neurogenic origin who are expected to have a normal vascular system. In order to investigate these parameters in 23 sexually active diabetic and nondiabetic males, penile arterial systems were evaluated by color Doppler ultrasonography. Parameters obtained from the cavernous arteries were arterial diameter (pre- and postpapaverine), diameter increase rate and systolic peak blood flow velocity. Systolic peak blood flow velocities in papaverine-induced erection were 36.75 (+/- 9.99) and 37.50 (+/- 13.18) cm/s for right and left cavernosal arteries, respectively, in nondiabetic 16 men. The mean cavernosal artery diameter changes were 89.23 and 77.93% for right and left cavernosal arteries. Systolic peak blood flow velocities were 24.57 (+/- 7.44) and 25.42 (+/- 9.45) cm/s and diameter increase rates were 78.57 and 37.50% for right and left cavernosal arteries in diabetic sexually active men. Sexually active diabetics have a significantly lower cavernosal artery peak blood flow velocity and diameter increase rate than nondiabetics (p < 0.01). Thus a subclinic dysfunction of erection might be introduced in diabetic males. In conclusion, each investigator should determine his own standards on sexually active subjects and on those with different etiologies such as diabetics mellitus, hypertension and hypercholesterolemia, contributing to erectile dysfunction.

Cryptorchidism: is orchidopexy always preventive treatment for infertility?

Cryptorchidism is one of the testicular factors recognized as preventable disease processes. Although the effect of bilateral cryptorchidism on fertility is well documented, more studies are required in order to determine the bilateral functional and histologic effects of unilateral cryptorchidism. This clinical retrospective study analyses the effects of cryptorchidism on fertility and histopathologic changes in dystopic and eutopic testes. Among 1400 patients consulted in our infertility clinic between the years of 1989 and 1993, 47 patients (3.3%) had cryptorchidism (29 unilateral/18 bilateral). Among these patients 26 had a history of orchidopexy (mean age at the time of operation: 13.11 +/- 5.24 years). Semen analyses (3x) were available in 43 and hormone profile in 27 out of 47. The incidence of abnormal semen parameters in unilateral and bilateral group was 89.6% and 100%, respectively. Testicular biopsies were obtained from 17 patients (10 with unilateral and 7 with bilateral disease). The biopsy findings in 75% of eutopic testes in unilateral group were similar to that of dystopic testis. The high incidence and significant histologic changes in eutopic testis supports the hypothesis that the disease might be bilateral in nature. The question whether the progression of the disease can be stopped by early orchidopexy still remains unanswered until long term follow-up studies are completed.

The effect of vinasse on the growth of Helianthus annuus and Pisum sativum: part I--The effects on some enzymes and chlorophyll and protein content.

In this study, the composition of vinasse was first analysed. It was found to contain 8.43% dry matter, 3.3% total ash, 4% crude protein and 0.95% total carbohydrates; BOD load was determined as 63 g litre(-1). Subsequently, the effects of vinasse in various concentrations (1, 2.5, 5, 10, 25, 50, 75 and 100%) on the activity of cellulase and pectin methyl esterase and the chlorophyll and protein contents of Pisum sativum and Helianthus annuus were investigated. The activity of these enzymes and the protein and chlorophyll contents in potted plants showed a gradual increase from the control up to 2.5% concentration of vinasse, but decreased at higher concentrations. These different effects of the effluent may be due to the high BOD load and the presence of cell wall cations in it.

Thyroid ultrasound in IDDM.

Insulin dependent diabetes mellitus (IDMM) is often associated with autoimmune thyroiditis (AIT) and a high prevalence of thyroid antibodies (TA). Ultrasound imaging of the thyroid may contribute to the evaluation of patients with AIT. We therefore investigated ultrasound findings of the thyroid in 83 IDDM patients (44F, 39M) with an age range of 2.3-22.3 yrs (median 11.1). Thyroid volume (ml) determined by ultrasound ranged between 1.3 and 17.9 (median 5.7). Thyroid volumes of 75 healthy children (32F, 43M) with an age range of 2.0 to 11.8 yrs (median 7.6) ranged between 1.6 and 13.2 ml (median 4.8) and did not show a significant difference from the IDDM group from age 4 to 12. TA were positive in 18.8% of the IDDM group. Thyroid volume was higher in TA (+) diabetics (p = 0.05), a finding which may be attributed to a higher percentage of cases with elevated TSH in the TA (+) group. Two diabetic patients showed non-homogeneous hypoechogenicity in the ultrasound compatible with AIT which was later confirmed in one of these cases by aspiration biopsy. Ultrasound imaging of the thyroid may contribute to the evaluation of patients with AIT in IDDM.

Posttraumatic high-flow priapism treated by N-butyl-cyanoacrylate embolization.

A patient with high-flow priapism was treated by transcatheter embolization of a posttraumatic left cavernosal arteriovenous fistula using N-butyl-cyanoacrylate (NBCA), resulting in complete detumescence. Erectile function has been preserved during a 3-month follow-up. Only two patients with NBCA embolization for high-flow priapism have been reported previously.
