Abstract The incidence of von Recklinghausen's disease is most frequent among neurocutaneous syndrome. It is an intractable neurological disease. About half of the disease is caused by an autosomal dominant inheritance and another half by mutation. It is characterized by neurofibroma which arises on various parts of the body and gradually increases with age. We recently encountered a case where a growth of neurofibroma within the foreskin had disturbed voiding.

OBJECTIVE: To study the role of tobacco in squamous cell carcinoma of the penis. SUBJECTS AND METHODS: The use of tobacco in the form of cigarettes, chewing tobacco and snuff was studied in a total of 503 patients and age-matched controls. RESULTS: By multivariate analysis, a significant association was found between smoking (P = 0.002) or chewing tobacco (P < 0.001) and the use of snuff (P = 0.004) in patients with penile carcinoma as compared with controls. A dose-response relationship was observed for both smoking and chewing. CONCLUSIONS: The use of tobacco is a significant risk factor for penile carcinoma, and the use of more than one form of tobacco increases this risk.
The American Academy of Pediatrics has stated that there is no valid medical reason for performing routine neonatal circumcision. Although the issue is hotly debated in medical circles, little attention has been given to the issue in the nursing literature. It is important that nurses understand the medical, social, religious, and child care issues involved in order to help parents make informed decisions regarding circumcision of their neonate.

One hundred consecutive cases of boys with foreskin problems referred to local paediatric surgeons in the Edinburgh area were studied. Fifty five underwent circumcision and the remainder were managed more conservatively with or without the use of local or general anaesthetic. Although sometimes avoiding general anaesthetic, the more conservative methods involved more frequent visits to the clinic, a larger number of complications, and a longer follow up period. Despite the vogue for conservatism, circumcision still has an important part to play in the management of troublesome foreskins in children.
AIMS/BACKGROUND: Compared with nanosecond (ns) pulses of conventional Nd-YAG lasers, picosecond (ps) laser pulses allow intraocular surgery at considerably lower pulse energy. The authors report initial clinical experiences using a Nd:YLF ps laser for the treatment of various indications for photodisruption. METHODS: A Nd:YLF laser system (ISL 2001, wavelength 1053 nm) was used to apply pulse series of 100-400 microJ single pulse energy at a repetition rate of 0.12-1.0 kHz. Computer controlled patterns were used to perform iridectomies (n = 53), capsulotomies (n = 9), synechiolysis (n = 3), and pupilloplasties (n = 2). Other procedures were vitreoretinal strand incision (n = 2) and peripheral retinotomy (n = 1). For comparison, 10 capsulotomies and 20 iridotomies were performed with a Nd:YAG ns laser. The ps laser cut of an anterior capsule was assessed by scanning electron microscopy (SEM). RESULTS: Open, well defined iridectomies (mean total energy 4028 mJ, mean diameter 724 microns), were achieved at first attempt in 92% of the cases. In 64% an iris bleeding and in 21% an IOP increase of > 10 mm Hg occurred. All capsulotomies were performed successfully (mean energy 690 mJ/mm cutting length) but with a high incidence of intraocular lens damage. The attempted vitreoretinal applications remained unsuccessful as a result of optical aberrations of the eye and contact lens. Although ps laser capsulotomies and iridectomies required much higher total energy than ns procedures, the resulting tissue effects of the ps pulses were more clearly defined. SEM examination of a ps incision of the anterior lens capsule demonstrated, nevertheless, that the cut was more irregular than the edge of a continuous curvilinear capsulorhexis. CONCLUSION: Series of ps pulses applied in computer controlled patterns can be used effectively for laser surgery in the anterior segment and are considerably less disruptive than ns pulses. The ps laser is well suited for laser iridectomies while the ns laser is preferable for posterior capsulotomies. As vitreoretinal applications remained unsuccessful, the range of indications for intraocular photodisruption could not be extended by the ps laser.

This paper reports seven cases of penile paraphimosis which occurred in both entire and castrated horses in association with general debility. Two cases were discharged after treatment while still suffering from partial paralysis; one was discharged at the owner's request with complete paralysis; three were destroyed and one died during treatment. Identified causes of debility were malnutrition, severe parasitism, glucose malabsorption and salmonellosis.

A 4-year follow-up study of 2 brothers affected by Schwartz-Jampel syndrome is reported. The children, aged 16 and 7 years, respectively, showed the clinical and electromyographical signs of the disorder. Further investigation showed some typical facial features of the syndrome, percussion myotonia and abnormal EMG pattern characterized by continuous muscle activity at rest in 3 other members of the same family. On the basis of our data, we suggest that inheritance of the Schwartz-Jampel syndrome may not only be recessive, as reported by most authors, but also dominant, with a different clinical expression.

Penile nerve block via the subpubic space was performed to relief the postoperative pain of children who underwent superficial surgery of the penis. Thirty-one male children were subdivided into two groups. After dorsal split procedure had been carried out under general anesthesia, 16 patients underwent subpubic penile nerve block (group 1), while 15 patients had no additional anesthetic procedure (group 2). Time to the first postoperative pain in group 1 was statistically longer than that in group 2 (p < 0.05). Most patients in group 1 did not require postoperative analgesics during the first 24 h after surgery. This technique appeared to be effective in relieving the postoperative pain of children who underwent superficial operation of the penis.
