[Surgical therapy of penis shaft induration in congenital penis deviation and induratio penis plastica].

The therapy of Peyronie's disease is an operative one primarily. Indication for the operative treatment is the penile deviation which prevents the patient from intercourse. The method of choice is plaque excision and subsequent corporoplasty with dermal graft. Good long-term results can also be achieved with a sole straightening of the penile shaft without plaque excision. However, this procedure (Nesbit's operation) results in a shortening of the length. In patients who are suffering from an additional erectile dysfunction an implantation of a penile prosthesis is done accompanied by plaque excision and a corporoplasty with alloplastic material (Dacron, Goretex). In 80% of all cases good postoperative results can be achieved with the operative treatment of Peyronie's disease. Patient's satisfaction is very good with all procedures described above. The exact diagnosis of the erectile quality seems to have a prognostic value for the postoperative result.

Nucleotide sequence of the penicillinase repressor gene penI of Bacillus licheniformis and regulation of penP and penI by the repressor.

Bacillus licheniformis penicillinase genes, penP and penI, are coded on a 4.2-kilobase EcoRI fragment of pTTE21 (T. Imanaka, T. Tanaka, H. Tsunekawa, and S. Aiba, J. Bacteriol. 147:776-186, 1981). The EcoRI fragment was subcloned in a low-copy-number plasmid pTB522 in Bacillus subtilis. B. subtilis carrying the recombinant plasmid pPTB60 (Tcr penP+ penI+) was chemically mutagenized. Of about 150,000 colonies, two penI(Ts) mutant plasmids, pPTB60D13 and pPTB60E24, were screened by the plate assay at 30 and 48 degrees C for penicillinase. By constructing recombinant plasmids between wild-type and mutant plasmids, the mutation points were shown to be located in a 1.7-kilobase EcoRI-PstI fragment. The EcoRI-PstI fragments of the wild-type plasmid and two mutant plasmids were sequenced. A large open reading frame, composed of 384 bases and 128 amino acid residues (molecular weight, 14,983), was found. Since the mutation points were located at different positions in the protein coding region (Ala to Val for pPTB60D13 and Pro to Leu for pPTB60E24), the coding region was concluded to be the penI gene. A Shine-Dalgarno sequence was found 7 bases upstream from the translation start site (ATG). A probable promoter sequence which is very similar to the consensus sequence was also found upstream of the penP promoter, but in the opposite direction. A consensus twofold symmetric sequence (AAAGTATTA CATATGTAAGNTTT) which might have been used as a repressor binding region was found downstream and in the midst of the penP promoter and also downstream of the penI promoter. The regulation of penP and penI by the repressor is discussed.

[Combined anesthesia with blockade of nn.dorsalis penis and inhalation anesthetics in surgery of the penis in children].

The studies were carried out in 21 patients with abnormalities of the penis (coronal and penile hypospadia, webbed penis) aged 5-15 years. Central hemodynamics, heart rate, and arterial pressure were evaluated at 6 stages of anesthesia and surgery. Premedication, induction, and maintenance anesthesia were carried out routinely. Laryngeal mask was used during maintenance anesthesia. The nn. dorsalis penis was blocked with 0.25% marcaine in a dose of 0.1 ml/kg for each side. The results indicate that penile blockade in combination with inhalation anesthesia is an effective method for anesthesiological protection of children operated on the penis.

The effect of a surgically created shunt between the corpus cavernosum penis and corpus spongiosum penis of stallions on erectile and ejaculatory function.

OBJECTIVE: To evaluate the effect of a shunt created between the corpus cavernosum penis (CCP) and corpus spongiosum penis (CSP) on erectile and ejaculatory function of normal stallions and to verify persistence of the shunt. STUDY DESIGN: The capability of stallions to develop an erection and to ejaculate was evaluated before and after creation of a corporeal shunt. Persistence of the shunt was determined by dye injection into the CCP at necropsy. ANIMALS: Six stallions. METHODS: A CCP-CSP shunt was created in five stallions. Semen was collected before and 4 to 14 weeks after surgery, before the horses were euthanatized. Dye was injected into the CCP to determine persistence of the shunt. Dye was also injected into the CCP of a control stallion. RESULTS: All stallions had normal erectile and ejaculatory function before and after surgery. Dye, injected into the CCP, entered the CSP in three of five treated stallions, demonstrating persistence of the shunt, whereas in two stallions, dye was found only in the CCP, indicating closure of the shunt. No dye was detected in the CSP of the control stallion. CONCLUSIONS: Creation of a corporeal shunt does not interfere with normal erection and ejaculation of stallions. Shunt closure is not necessary for stallions to retain normal erectile and ejaculatory function. CLINICAL RELEVANCE: Failure of a stallion affected by priapism to achieve normal erection or to ejaculate after creation of a corporeal shunt would likely be because of damage to corporeal tissue than from an effect of the shunt.

[Total denudation of the penis in circumcision. Description of a plastic technique for repair of the penis].

The difficulty of knowing the percentage of newborns and infants who have been circumcised in our medium, and the presence in the Surgical Pediatric Ward of our hospital, during the last five years, of patients with total denudation of the penis--secondary to a circumcision with plastibel, drove us to research and share our experience in the use of a free skin graft for its correction, the postoperative care needed and the follow-up of those patients. Circumcision is a surgical procedure which is not totally innocuous and which should be performed by surgically experienced personnel to obtain good results. It is recommended that general practitioners and pediatricians be informed that the denudation of the penis is an infrequent but severe complication, and how to avoid its occurrence.

Penis tuberculid (papulonecrotic tuberculid of the glans penis): treatment with a combination of rifampicin and an extract from tubercle bacilli (T.B. vaccine).

A case of penis tuberculid (papulonecrotic tuberculid of the glans penis) and its treatment with combination of oral rifampicin (RFP) and injection of an extract from tubercle bacilli (T.B. vaccine) were reported. We also examined the literature and discovered 37 cases of this disease in Japan in the last 10 years (between 1978 and 1987).

Penis tuberculides: papulonecrotic tuberculides on the glans penis.

Two cases of penis tuberculides are described. Although this disease once used to be comparatively common in Japan, the number of people affected by the disease has recently decreased as the prevalence of tuberculosis has fallen. However, we can still find a few cases in the Japanese literature every year. Outside Japan, we can hardly find reports of this disease, except for a few cases reported under the title of 'Papulonecrotic tuberculides on the penis' from Northern European countries. In addition to reporting 2 cases, we summarize clinical features of this disease. Racial predisposition or endemic factors may be related to the tuberculides in such a special site.

[Two cases of giant condyloma of the penis treated with penis-sparing methods].

Herein, we report two cases of giant condyloma of the penis treated with penis-sparing methods. In the first case, the papillomatous tumor disappeared with topical use of fluorouracil ointment. In the second case, the tumor was treated with topical use of fluorouracil or bleomycin hydrochloride, followed by the resection of tumor. Giant condylomas reported in the recent 13 years are reviewed and methods of treatment discussed.

The penis is not protected--in hypertension there are vascular changes in the penis which are similar to those in other vascular beds.

In hypertension, small arteries in a variety of vascular beds undergo structural changes that increase resistance. To assess whether there are differential structural changes in the penis that accompany hypertension, we began with determining structurally-based vascular resistance properties in penile and hindlimb vascular beds of adult spontaneously hypertensive rats (SHR) and Sprague-Dawley (SD) rats. In anesthetized SHR, the penile and hindlimb vasculature were isolated and perfused, maximum dilation was induced, and a flow-pressure assessment and alpha 1-adrenoceptor agonist concentration-response curves were generated. Both the baseline and maximum constrictor responses were similar in the two beds of each strain, and overall the maximum structurally-based vascular resistance in SHR was higher than in SD rats. Our data suggests that the penile vasculature is not protected from the structural changes that take place in the other vascular beds in hypertension. There does not appear to be an underlying functional control mechanism that protects the penile vasculature from structural changes that may have a negative impact on penile blood flow.

[Strangulation of glans penis by hair or "penis tourniquet syndrome"].

The authors report 5 cases of strangulation of the penis with hair in children. This affection, more seen frequently within socially disadvantaged children, needs early diagnosis and treatment because it may be responsible for glans amputation. A better knowledge of this accident by parents and physicians might prevent this barbaric aggression.
