Medical and surgical management of priapism.

Priapism is a pathological condition of penile erection that persists beyond, or is unrelated to, sexual stimulation. Pathologically and clinically, two subtypes are seen-the high flow (non-ischaemic) variety and the low flow (ischaemic) priapism. The low flow type is more dangerous, as these patients are susceptible to greater complications and the long term recovery of erectile function is dependent on prompt and urgent intervention. Many of the causes of priapism are medical, including pharmacological agents, and as such, priapism should be considered as a medical and surgical emergency.

Molecular changes in prostatic cancer.

Prostate cancer is one of the most commonly diagnosed and potentially devastating cancers in men, throughout the world. However, the clinical manifestation of this disease varies greatly, from indolent tumours, requiring little or no treatment, to those aggressive cancers which require radical therapies. Prostate cancer, like all other cancers, develops and progresses as a consequence of an accumulation of genetic changes. While several putative genes have been isolated for the development of breast, ovarian and colon cancer, the aetiology and pathogenesis of prostate cancer remains poorly understood. In this review, we discuss important genetic markers in early, metastatic and hormone refractory prostate cancer which may, in the future, be used as markers for diagnosis and prognosis, as well as targets for therapeutic intervention.

Autonomic dysreflexia: a medical emergency.

Autonomic dysreflexia is an important clinical diagnosis that requires prompt treatment to avoid devastating complications. The condition may present itself to all members of medical and surgical specialties, who may not be accustomed to treating it. It is the clinician's responsibility to have a basic understanding of the pathophysiology of the condition and the simple steps required to treat it.

Testicular torsion: a twist to the tale.

Testicular torsion is a surgical emergency that requires prompt exploration if testicular viability is to be maintained. Although rare, it is essential to be aware that it may occur despite previous fixation (orchidopexy). Testicular torsion occurring after previous orchidopexy is rare, but recognition of this possibility is essential to prevent testicular infarction and subsequent orchidectomy. During scrotal exploration a wide variety of methods for orchidopexy exist. We present a case of testicular torsion despite previous fixation and discuss the merits of various techniques available for orchidopexy.

Intratesticular cysts and malignant potential: conservative management is an option.

Benign intratesticular cysts are rare, but recognition is essential to prevent unnecessary surgical intervention. The diagnostic dilemma is to differentiate these cysts from testicular malignancy. As they are extremely uncommon, experience of their management is limited and controversial. We present a case of a simple intratesticular cyst and discuss the diagnostic and management principles.

Testicular torsion unravelled.

Testicular torsion is a true vascular emergency-prompt diagnosis and surgical management is critical. If treatment is not instigated within 4-6 hours of the onset of pain, irreversible testicular infarction may result, necessitating orchidectomy. This review presents the key features, management principles and medicolegal considerations of this serious condition.
