Penile carcinoma: a challenge for the developing world.

Although rare in developed countries, carcinoma of the penis is an important problem in the developing world. Circumcision done in childhood offers the greatest protection against this disease. Poor penile hygiene and phimosis are strong risk factors for development of penile carcinoma. Early disease can be treated by conventional resection of the penis, or in selected patients by organ preserving techniques including Mohs micrographic surgery, and laser and radiation therapy. For more advanced primary disease, partial or total penectomy is needed. Elective or therapeutic lymph-node dissection is recommended for inguinal metastatic disease, and depending on the disease status, unilateral or bilateral inguinal or ilioinguinal lymphadenectomy might be needed. The role of chemotherapy, as adjuvant or primary treatment in metastatic disease, needs to be defined in prospective clinical trials, which can be done in developing countries.

Pagetoid dyskeratosis of the prepuce. An incidental histologic finding resembling extramammary Paget's disease.

BACKGROUND: Pale cells resembling those of paget's disease have been seen as an incidental finding within the epidermis in a variety of benign papules most commonly located in intertriginous areas. This lesion, called pagetoid dyskeratosis, is considered a reactive process in which a small part of the normal population of keratinocytes is induced to proliferate. Among the inductors friction is suspected. As far as we know, these cells have not been reported in the penis. METHODS: Here we describe the location of the lesion in the foreskin and the incidence of this lesion in a group of 281 unselected patients surgically treated for phimosis. In selected cases histochemical staining and immunohistochemical studies were performed. RESULTS: Pagetoid dyskeratosis was found in 105 cases (37.4%) but only in 5 cases (1.8%) the lesion was conspicuous. The cells of pagetoid dyskeratosis show an immunohistochemical profile different from the surrounding keratinocytes characterized by premature keratinization. Pagetoid dyskeratosis cells must be distinguished from the artefactual clear cells of the epidermis, from reactive melanocytes, and from pale-cell acanthosis. In cases in which pagetoid dyskeratosis shows a florid expression there is a hazard of overdiagnosis to the patient. The main differential diagnosis includes extramammary Paget's disease, pagetoid squamous cell carcinoma in situ, epidermotropic metastasis, superficial spreading malignant melanoma, clear cell papulosis, and penile koilocytoses. CONCLUSIONS: The pathologist should be familiar with the histologic features of pagetoid dyskeratosis in the foreskin in order to avoid misdiagnosis and unnecessary treatment. Routine histologic study is usually sufficient to identify the lesion.

Granisetron reduces post-operative vomiting in children: a dose-ranging study.

This study was undertaken to determine the minimum effective dose of granisetron, 5-hydroxytryptamine type 3 receptor antagonist, for the prevention of post-operative vomiting in children undergoing general inhalational anaesthesia for surgery (inguinal hernia and phimosis). In a randomized, double-blind manner, 120 children, ASA physical status I, aged 4-10 years, were assigned to receive placebo (saline) or granisetron at three different doses (20 micrograms kg-1, 40 micrograms kg-1, 100 micrograms kg-1) intravenously immediately after inhalation induction of anaesthesia (n = 30 of each). A complete response, defined as no emesis and no need for another rescue antiemetic during the first 24 h after anaesthesia, occurred in 57% with placebo, 67% with granisetron 20 micrograms kg-1, 90% with granisetron 40 micrograms kg-1 and 90% with granisetron 100 micrograms kg-1 respectively (P < 0.05; overall Fisher's exact probability test). No clinically important adverse events were observed in any of the groups. Our results suggest that granisetron 40 micrograms kg-1 is the minimum effective dose for the prevention of emesis after paediatric surgery, and that increasing its dose to 100 micrograms kg-1 provides no demonstrable benefit.

Prophylactic therapy with combined granisetron and dexamethasone for the prevention of post-operative vomiting in children.

This study was undertaken to compare the efficacy and safety of granisetron, a 5-hydroxytryptamine type 3 receptor antagonist, and dexamethasone and each drug alone for the prevention of post-operative vomiting by children, with no history of motion sickness and/or previous post-operative vomiting, undergoing general inhalational anaesthesia for surgery (inguinal hernia and phimosis). In a randomized, double-blind manner, 150 children, ASA physical status 1, aged 4-10 years, were assigned to receive granisetron 40 mg kg-1, dexamethasone 150 mg kg-1, or granisetron 40 mg kg-1 plus dexamethasone 150 mg kg-1 intravenously immediately after inhalation induction of anaesthesia (n = 50 of each). A complete response, defined as no emesis and no need for another rescue anti-emetic during the first 24 h after anaesthesia, was 86% with granisetron, 68% with dexamethasone and 98% with granisetron plus dexamethasone, respectively (P < 0.05; overall Fisher's exact probability test). No clinically serious adverse events were observed in any of the groups. In conclusion, prophylactic therapy with combined granisetron and dexamethasone was more effective than was each anti-emetic alone for the prevention of vomiting after paediatric surgery.

Kindler syndrome.

Kindler syndrome is a rare genodermatosis characterized by acral bullae and photosensitivity. The photosensitivity improves with advancing age and results in progressive poikiloderma and cutaneous atrophy, and many additional features have also been described. This report describes two male Kindler syndrome patients with classical features of acral blistering and photosensitivity in childhood, and subsequent development of poikiloderma, leukokeratosis of oro-ano-genital mucosae, phimosis and meatal stenosis. The first patient had additional ophthalmic features of chronic simple conjunctivitis caused by persistent irritation, multiple stromal nebular corneal opacities and thickened corneal nerves. The second patient showed skeletal changes, namely a dome-shaped skull (turri-cephaly), bifid fourth rib, missing fifth rib, short fourth and fifth metacarpals and mandibular abnormalities. This is the first report of such ophthalmic and skeletal features of Kindler syndrome.

Meatus tightly covered by the prepuce is associated with urinary infection.

BACKGROUND: Almost all newborns have phimosis, which is known as one of the risk factors for urinary infection. The present study analyzed which specific prepuce conditions correlated with the development of febrile urinary infection in Japanese male infants. METHODS: The subjects consisted of 100 children, 64 boys and 36 girls, with febrile urinary infection. Prepuces were classified by their retractability in the male patients and in 714 healthy boys. RESULTS: Ninety-four percent of first febrile urinary infections occurred before 7 months of age in boys, whereas only 37% of the girls had first infections by that age. The prepuce covered the external urethral meatus in 96% of the healthy boys aged 3 years or less. A gentle retraction maneuver could not uncover the urethral meatus in approximately 40% of the boys aged 0-6 months. The frequency started to decline spontaneously after that age. Male patients aged 0-6 months significantly more often had tightly covered meatus than did healthy neonates (85%vs 42%, P < 0.0001). CONCLUSIONS: These findings indicate that it is specifically those boys whose external urethral meatus are tightly covered with foreskin who constitute the high-risk group for urinary infection. Awareness of this observation should help with diagnosing and managing urinary infection in young boys.

Persistent anaphylactic reaction after induction with thiopentone and cisatracurium.

A 6-year-old boy presented for surgery for phimosis. The anaesthetic technique included intravenous induction with thiopentone and neuromuscular blockade with cisatracurium. Severe persistent bronchospasm and central cyanosis followed the administration of these drugs. A continuous i.v. infusion of epinephrine at 0.2 microg. kg(-1) x min(-1) was necessary to break the severe refractory bronchial hyperresponsiveness. There was no previous exposure to anaesthetic drugs and no definite family history of allergy. Through increased serum eosinophil cationic protein, tryptase and histamine levels and IgE levels specific to cisatracurium, we demonstrated an IgE-mediated anaphylactic reaction to cisatracurium in the child's first exposure to this new neuromuscular blocking agent. Anaphylactic reactions to new anaesthetic drugs may be challenging to recognize and treat during general anaesthesia in children. The pathogenesis, diagnosis and management of life threatening persistent allergic reactions to intravenous anaesthetics are discussed.

"Triple incision plasty". A convenient procedure for preputial relief.

Circumcision is the accepted operation to treat phimosis. However, when the purpose is to achieve retractility of a narrow foreskin to avoid further scarring and phimotic development after recurrent balanitis, a preputial plasty might be sufficient. Several methods with single or multiple incisions have been introduced throughout the years. None of them seems to have gained general acceptance. Single plasties tend to give cosmetically unsatisfactory results with an apparent cleft or deformity, while the multiple ones, where the deformity is more or less spread around the circumference, are not always easily done, at least not in children. Still, circumcision seems to remain the standard procedure for preputial relief. A simple technique, where three longitudinal incisions are transversely sutured, is described. It has been used in a series of 63 consecutive patients with good results, and seems to offer a good compromise between simplicity and cosmetical demands.

Epidemiological aspects of cancer of the penis in Finland.

The purpose of this study was to characterize the epidemiological features of cancer of the penis in Finland. After histological re-examination and exclusions, the final series comprised 269 patients with cancer of the penis diagnosed and reported to the Finnish Cancer Registry between 1955 and 1977. The age-adjusted incidence rate of cancer of the penis decreased slightly from the 1960s onwards and was on the order of 0.5 per 100,000 person-years in the 1970s. Cancer of the penis was a disease of elderly males, which showed no systematic geographical variation in Finland in terms of risk. The most frequent predisposing factors were phimosis, in 44% of the cases, and condylomatous lesions, in 20% of the cases. The general survival (all patients, all stages) was favourable; the 5-, 10-, and 20-year relative survival rates were 71, 69 and 78%, respectively.

Outcome after repair of congenital penile malformations.

Penile malformations seen and treated during childhood may result in voiding disorders and sexual malfunction in adults. Preputial synechia and phimosis will seldom be the reason for these problems, although some men do seek treatment to correct radical circumcision. Little is known about the satisfaction of men with neonatal or childhood circumcision. Congenital penile curvature is seen in 0.4-0.6% of men. Slight bends do not need any operative treatment and young men should be given advice and counselling accordingly. If treatment is needed, a standard Nesbit procedure or one of its modifications is used in order to avoid urethral manipulation. A hypospadiac position of the urethral meatus together with a more or less prominent ventral bending of the penis is seen in another 0.3-0.5% of boys. Reports on more than 200 operations to correct this deformity have been published. Between 5 and 25% of early complications such as fistula formation, stenosis of the neourethra and skin problems result from hypospadias repair. Long-term follow-up studies have shown that adulthood satisfaction with respect to voiding and sexual function is achieved in 2/3 and some degree of dissatisfaction in 1/3 of cases. Epispadias repair is a much more complicated procedure and long-term results are seldom reported. Nevertheless, quite good results with respect to continence (approximately 80%) and sexual function may be achieved.

Lichen planus in a child requiring circumcision.

Lichen planus is a rare disorder in infants and children where it usually has the classical cutaneous pattern and only exceptionally involves the mucosa and skin appendages. A 9-year-old boy was referred to our department with a 4-month history of erythematous keratotic papules on the trunk and the upper and lower limbs. There were no signs of mucosal involvement. Subsequently white papules and striae, occasionally forming a lace like pattern, appeared on the penis and prepuce which quickly led to phimosis necessitating circumcision. Histologic examination of skin biopsy specimens and genital mucosa fragments confirmed the clinical diagnosis of lichen planus.

A study of clinical opinion and practice regarding circumcision.

AIM: To establish clinical opinion regarding appropriate indications for circumcision and to examine actual clinical practice. METHODS: A questionnaire was sent to all NHS hospital consultants in the Yorkshire region of the UK identified as having a role to play in the management of boys (under 16 years of age) requiring circumcision. Retrospective data on actual clinical practice during a three month study period were also collected via a simple proforma. RESULTS: Of 153 questionnaires sent, 64 were returned. Responses revealed varying opinions regarding appropriate indications for circumcision within each consultant group, and between paediatricians and surgeons. Surgeons were generally more inclined to recommend circumcision for each of the indications listed in the questionnaire. Analysis of clinical practice revealed that almost two thirds of procedures were carried out for phimosis, and nearly half of these children were under the age of 5 years. CONCLUSION: There are differences in the clinical opinions of surgeons and paediatricians on what constitutes an appropriate indication for circumcision. Paediatricians' opinions are generally more in line with current evidence than those of surgeons, possibly resulting in many unnecessary circumcisions.

A prospective survey of the indications and morbidity of circumcision in children.

Both the British Medical Association and the American Academy of Pediatrics recommend that circumcision should only be performed for medical reasons. No one has ever described which reasons are actually used, nor measured the morbidity of the procedure. Of 140 boys coming to day-case elective circumcision between the ages of 3 months and 14 years (mean 4.3 years), the commonest cause was a congenital phimosis (42.8%). Four (2.8%) patients required acute readmission postoperatively, and a further 4 developed meatal stenosis, requiring a formal meatotomy. Of 99 patients followed up in detail, 46% vomited, 36% oozed, 19% did not pass urine for more than 12 h and 26% could not wear pants for more than 7 days. Childhood circumcision has an appreciable morbidity, and should not be recommended without a medical reason.

Ectopic modified sebaceous glands in human penis.

The balanopreputial sulcus is believed to be the most frequent site of the so-called Tyson's glands. The intriguing feature of these anatomical structures is their mere existence, which has been doubted. Herein, the authors present a case of a 24-year-old man who underwent surgical treatment of his phimosis. On microscopic examination of the specimen, glands with morphological features similar to those described by Tyson were noted.

Lichen sclerosus et atrophicus. Findings after complete circumcision.

We prospectively evaluated 75 patients, 30-77 years old, with severe phimosis. All patients were treated surgically by complete circumcision and all surgical specimens were sent for histological evaluation. All patients with histologically proven lichen sclerosus et atrophicus (LSA) (eight patients, 10.6%) were re-evaluated 6 months postoperatively, and all but one were examined 5 years after the operation. All patients with histologically proven balanoposthitis (BP) (47 patients, 62.6%) were also re-evaluated 6 months postoperatively, and 41 patients 5 years after surgery. This group (BP) was the control group of our study. Six months after the operation, the eight patients with histologically proven LSA all had an excellent convalescence, and the lesions observed during the operation resolved in four patients and regressed in two patients. In one patient the glans presented with a pale grey-white-coloured plaque. Biopsy was performed and a well-differentiated squamous cell carcinoma infiltrating the glans was revealed. The control group of patients with histologically proven BP were also re-evaluated 6 months and 5 years after surgery. An excellent convalescence was observed in all patients who completed the follow-up examination. Care must be taken not to underestimate the potential relationship between LSA and squamous cell carcinoma, because the latter is usually invasive, very aggressive and requires immediate treatment.

Kindler syndrome.

Kindler syndrome is a rare autosomal recessive disorder associated with skin fragility. It is characterized by blistering in infancy, photosensitivity and progressive poikiloderma. The syndrome involves the skin and mucous membrane with radiological changes. The genetic defect has been identified on the short arm of chromosome 20. This report describes an 18-year-old patient with classical features like blistering and photosensitivity in childhood and the subsequent development of poikiloderma. The differential diagnosis of Kindler syndrome includes diseases like Bloom syndrome, Cockayne syndrome, dyskeratosis congenita, epidermolysis bullosa, Rothmund-Thomson syndrome and xeroderma pigmentosum. Our patient had classical cutaneous features of Kindler syndrome with phimosis as a complication.

Circumcision: a refined technique and 5 year review.

The vast majority of circumcisions currently performed in the UK are for phimosis or balanitis and the patients are not looking for the denuded glans appearance of a ritual circumcision. We present a refinement of the sleeve technique of circumcision, which involves Horton's test to define the proximal incision margin, and bipolar electro-dissection. A review of all patients undergoing circumcision at the Wordsley Plastic Surgery Unit, in a 5-year period, has shown this technique to be safe with a haematoma rate of only 1.4%, and an overall complication rate of 3%.

Preputial calculi: a case report.

The patient was a 92-year-old male whose chief complaint was urinary retention. The X-ray film showed multiple overlapping calcification shadows in the penile region. Renal insufficiency was speculated to be due to post-renal obstruction. Under the diagnoses of closure of the preputial orifice by balanoposthitis followed by urinary retention and preputial calculi, an urgent dorsal incision of the prepuce was made. Then, stone removal and indwelling catheter placement were performed. Renal function recovered soon after the operation, and the patient could urinate freely without catheterization. This case reminds us of the significance of surgical treatment for phimosis in elderly patients.
