Black widow spider envenomation (BWSE) is commonly associated with severe abdominal pain, muscle cramping, and hypertension. Treatment is primarily symptomatic with the use of opiates and benzodiazepines. Priapism is a complication of BWSE that has only rarely been reported. We describe a 17-month-old male who developed priapism after known BWSE. His priapism did not respond to opiates or benzodiazepines, and he was treated with black widow spider antivenin. Complete detumescence followed within several hours. The patient required no additional opiates for pain and was discharged from the hospital the following day. The patient's rapid improvement after antivenin suggests its efficacy in treating BWSE-associated priapism.

Sickle cell disease is an inherited disease characterized by the presence of an abnormal haemoglobin. It is the more prevalent genetic disease at birth in Ile-de France area. Sickle cell disease can be complicated by acute vaso-occlusive crisis, chronic visceral involvement related to ischemic process, and infectious complications. In adults, acute vaso-occlusive crisis is the major clinical problem prompting admission to hospital and the main cause of death. It mainly manifests by osteoarticular pain and acute chest syndrome and can be complicated by multiorgan failure. Acute vaso-occlusive crisis can be also manifested by priapism, ischemic or haemorrhagic stroke, or abdominal pain. The main treatment of severe acute vaso-occlusive crisis is based on transfusion.

Intracavernous injection of Trimix (Tx) is indicated for patients unsuitable for prostaglandin E1 (PgE1) injection due to lack of response, pain or cost. We believe that the ideal ratio of ingredient doses in Tx is yet to be found. We postulated that increasing the doses of individual drug components in an orderly manner would convey important data on penile hemodynamic response. Such information is needed to choose an effective and less costly alternative to PgE1 with least side effects. We set out to evaluate the impact of varying the ingredient dosage on response and short-term safety of Tx compared with PgE1. We prospectively randomized 180 consecutive patients with erectile dysfunction into nine equal groups and each group received a different dose of Tx, namely phentolamine (1 mg) plus one dose of PgE1 (2.5, 5 or 10 microg) and one dose of papaverine (5, 10 or 20 mg). Each patient was injected with 20 microg PgE1 and one dose of Tx in two clinic visits 1 week apart. Following injection, duplex ultrasound of cavernous arteries and axial rigidometry were carried out. Patients ranked the quality of erection, estimated overall satisfaction and reported time to detumescence and side effects. Patients' mean age was 50.5+/-11.7 y with underlying organic condition in 91.1%. There were no significant differences between PgE1 and Tx with regard to peak cavernous artery flow, time to erection, patients' satisfaction, average axial rigidity and pain. PgE1 produced higher end diastolic velocity, shorter duration of erection and less priapism. Patients did not show a preference for either drug or any particular dosage. We conclude that even at the smallest dose of ingredients of Tx, there are no significant differences in hemodynamic effects, rigidity, pain and self-satisfaction between the two drugs. However, Tx produces a longer duration of erection and more priapism than PgE1.

A retrospective study was conducted in nine patients with rabies admitted to a hospital of Fortaleza, Brazil. Autopsy was performed in all cases. The ages ranged from three to 81 years and six were males. They all were bitten by dogs. The time between the accident and the hospital admission ranged from 20 to 120 days (mean 45 +/- 34 days). The time until death ranged from one to nine days (mean 3.3 +/- 5.5 days). The signs and symptoms presented were fever, hydrophobia, aerophobia, agitation, disorientation, dyspnea, sialorrhea, vomiting, oliguria, sore throat, pain and hypoesthesia in the site of the bite, headache, syncope, cough, hematemesis, mydriasis, hematuria, constipation, cervical pain and priapism. In three out of six patients, there was evidence of acute renal failure, defined as serum creatinine > or = 1.4 mg/dL. The post-mortem findings in the kidneys were mild to moderate glomerular congestion and mild to intense peritubular capillary congestion. Acute tubular necrosis was seen in only two cases. This study shows some evidence of renal involvement in rabies. Histopathologic findings are nonspecific, so hemodynamic instability, caused by autonomic dysfunction, hydrophobia and dehydration must be responsible for acute renal failure in rabies.

Priapism is defined as prolonged and painful penile erection that does not subside on orgasm. It is considered to be a urological emergency. However, patients do not always seek prompt medical help. The incidence of priapism is increased by sickle cell disease, where it is a complication of the characteristic sickling of the red blood cells. Little is known about the psychological or social implications of this complication or the strategies that sickle cell patients use to manage it. A qualitative study was carried out in order to investigate these topics. Semi-structured interviews were carried out with adult male patients of the Sickle Cell and Thalassaemia Centre in Birmingham in the UK who experienced priapism. These were subsequently analysed using grounded theory. Ten themes were elicited: first occurrence of priapism, pain, precipitants, emotional consequences, self-management, experience of hospital, impact on work and social life, impact on sexual relationships, erectile dysfunction, and disclosure. The dominant experiences were ones of despair, embarrassment, and isolation. Participants described finding it difficult to disclose priapism, with the result that it was often unreported until late in its course. Attempts to manage priapism at home varied, with there being little consensus on their efficacy. The results are discussed with respect to the healthcare services that cater for these patients.

In daily clinical practice, the frequency of painful crises (pain rate) is an important parameter of sickle cell disease severity. We assessed the prevalence of sickle cell disease-related organ damage and complications and their relation to pain rate. Organ damage and history of vaso-occlusive complications were obtained via systematic screening of consecutive patients and by chart review. In 104 adult sickle cell patients pain rate was related to a history of acute chest syndromes, avascular osteonecrosis, iron overload, priapism and cholelithiasis. However, major disease-related complications, such as microalbuminuria and pulmonary hypertension, were detected in 23% and 24% respectively of patients without painful crises in the study period underlining the importance of systematic screening for developing organ damage in sickle cell patients irrespective of pain rate.

Erectile dysfunction (ED) is becoming an increasingly common problem and although oral therapies offer first-line treatment for many men, they are contraindicated or ineffective in substantial groups of patients. Intracavernosal injection (ICI) therapy is the most effective nonsurgical treatment for ED and offers an effective alternative to oral therapy. Sufficient arterial blood supply and a functional veno-occlusive mechanism are prerequisites in the attainment and maintenance of a functional erection. Invicorp (Plethora Solutions, London, UK) is a combination of vasoactive intestinal polypeptide (VIP) 25 microg and phentolamine mesylate 1 or 2 mg for ICI in the management of moderate to severe ED. The two active components have complementary modes of action; VIP has a potent effect on the veno-occlusive mechanism, but little effect on arterial inflow, whereas phentolamine increases arterial blood flow with no effect on the veno-occlusive mechanism. Clinical studies showed that Invicorp is effective in >or=80% of men with ED, including those who have failed to respond to other therapies and, unlike existing intracavernosal therapies, is associated with a very low incidence of penile pain and virtually negligible risk of priapism. We estimate that there are >5.9 million men in the USA alone for whom oral ED drugs are not a viable treatment option, and for whom Invicorp might offer a safe and effective alternative.

A hemolysis-linked subphenotype of sickle cell disease (SCD), characterized by pulmonary hypertension, stroke, priapism and leg ulcers, is associated with decreased nitric oxide bioavailability and vasculopathy. Vasculopathy appears to have a multifactorial etiology, including mechanisms primarily that involve deficient nitric oxide (NO) signaling, but also involving altered function of NO synthase related to substrate availability and cooperating factors such as apolipoproteins. Improved understanding of the vascular pathophysiology of SCD has led to new vascular targets for translational research in SCD. This growing vascular therapeutics field in SCD is complementary to the ongoing efforts to reduce the morbidity of vaso-occlusive pain crisis. This presentation will review the current biology and translational clinical development of novel small molecules targeting sickle cell vasculopathy. Strategies targeting the hemeoxygenase-carbon monoxide pathway, the arginine-NO synthase-cGMP-phosphodiesterase 5 pathway, the nitrate-nitrite-NO pathway, and the apolipoprotein A-I pathways will be reviewed. In this context, current clinical trials of inhaled NO, CO, nitrite, sildenafil and apoA-I mimetics will be discussed.

A 12-year-old boy had been suffering from intermittent episodes of penile erection for 2 weeks. For the last 2 days, however, the patient had been having sustained priapism and had to be admitted in a private hospital for management. Investigations revealed high total leukocyte counts. He was referred to the authors' hospital where a diagnosis of chronic myeloid leukemia was made. He was started on intravenous hydration, hydroxyurea, and allopurinol. Imatinib was added 2 days later. The parents refused surgical intervention. Despite a reduction in the counts the priapism persisted and the pain was unresponsive to opioids. Administration of terbutaline was associated with a successful outcome resulting in relief from pain within 20 min. The priapism also resolved completely in 1 day.
