In a series on celebrities and their health, the BBC News website talks to former England international rugby player Andy Ripley about his battle with prostate cancer.

Andy, 59, played number eight for England between 1972-6.

An all-round athlete, he is also a qualified yachtsman, ran 400 metres in the UK athletics championship, was World Veteran indoor rowing champion and champion of the World Superstars television series.

HOW DID YOU FIRST REALISE SOMETHING WAS WRONG?

I had been at a friend's party in June 2005 and I remember we drove back home. We live in the middle of nowhere.

I was feeling very cold and had a huge pain in my chest. My wife said she would call for an ambulance, but I said not to.

She called NHS direct and they said I could be having a heart attack and sent an ambulance.

The doors opened and these guys in green jumped out of the back. They said how much they had admired my playing.

They took me to East Surrey Hospital. They were great.

HOW DID YOU GET DIAGNOSED?

They did all the heart tests and found it was a pulmonary embolism (a blood clot that blocks an artery in the lungs), but they did not know what had caused it and so did a series of tests.

Although it was not routine one of the nurses did a PSA test and the results came back that my levels were 133.

I remember saying 'Is that good? and she said 'no'.

I then needed to have four digital rectum examinations.

My prostate cancer was only picked up because I was in hospital. I had not had any of the symptoms, such as weeing a lot in the night.

I was in the hospital for 20 days and became almost pyjama institutionalised.

Because I was on a heart ward, people would come in and spend four days in hospital and by then would either have been moved elsewhere or sent home.

I was like the 'old lag', I saw so many people come and go.

I had a biopsy and was told it was locally advanced prostate cancer.

I knew little about prostate cancer, but I row for a veterans' team and one of the veterans had told us that he had the early stages of prostate cancer.

He told us all to go and get tested, but the next week none of us had.

Ironically while I was commiserating with him my levels were already in triple figures.

WHAT WAS YOUR REACTION TO THE DIAGNOSIS?

I felt unbelievably strong. I have three children and have been married for 30 years.

The pulmonary embolism could have killed me, but it didn't.

I have had this cancer for 20 months now and I have seen people with cancers at the Royal Marsden being corroded from within and perhaps that is the future destiny, but at the moment I have no symptoms.

The only hard part was telling my three children. I told them when they came home. They knew I had been in hospital and I said 'I have locally advanced prostate cancer' and we had a group hug.

Cancer is a big word.

WHAT WAS YOUR TREATMENT?

There was no point having any surgery as it was certain to have spread outside the prostate, because they got it so late.

They gave me hormone treatments Zoladex and Casodex to shrink the tumour, although it is not a cure.

HOW DID YOU FEEL DURING THE TREATMENT?

I felt fine. The Zoladex cuts off the testosterone and that can lead to hot flushes, although I have not really had any.

I have been on it for 12 months.

I have no libido whatsoever. I can still have an erection, but I have no drive, although I do still occasionally have sex.

But there are also upsides to the treatment. It has made my skin very soft and I shave now just out of habit. It has made me feel more feminine.

For the first time I now love shopping.

HOW DO YOU FEEL NOW?

The treatment does appear to have worked. My PSA levels are undetectable and they gave me radiotherapy.

They kept me on the hormone treatment, but I have asked to come off it because I want a go at the world indoor rowing championship at 60. My doctor thought it was so I could have sex and asked if I wanted Viagra.

I said no, it really was for the world indoor rowing championship and he said I was a sad man. Life is wonderful and I want to enjoy it.

WHAT IS YOUR MESSAGE TO OTHER PEOPLE WITH THE SAME CONDITION?

Everybody is different and they need to go their own way, their own route.

I would say to them not to give up their control - it is their cancer.

My life has been enhanced and since I had cancer, I have never loved so much or been loved so much.

Find out what you can about your cancer and make your choices.

Enjoy every day and remember life is wonderful and a thing of value.

Sonographic penile anatomy

The penis is composed of two dorsal corpora cavernosa and one ventral corpus spongiosum. The two corpora cavernosa are enclosed in a fibrous sheath, the tunica albuginea, which partially covers the corpus spongiosum. The tunica albuginea is composed of elastic fibers that form an irregular, criss-crossing strips network on which collagen fibers rest. The corpora cavernosa are composed of sinusoidal spaces lined by smooth muscles (erectile tissue) and endothelium. The glans penis is formed by expansion of the corpus spongiosum. The corpus spongiosum is traversed throughout its length by the anterior urethra, which begins at the perineal membrane. The corpus spongiosum provides support to the urethra and helps with the expulsion of semen from the urethra. Buck's fascia surrounds both cavernosal bodies dorsally and splits to surround the spongiosum ventrally (Figure 1a and b). The penile blood vessels arise from the internal pudendal artery. The penile artery divides into two main branches, the dorsal penile artery and the cavernosal artery. The cavernosal artery enters the corpus cavernosum on the superomedial surface of the penis. The branches of this artery are called the helicine arteries and subsequently divide into smaller vessels that communicate with the lacunae of the corpus cavernosum (Figure 1c and d). The venous blood is returned by the venous plexus beneath the tunica albuginea. The emissary veins perforate the tunica albuginea, and the blood is drained by the venae circumflexae into the deep dorsal veins.

A free viagra medicament or a no-cost attempt of activity pills are examples of production offers to U.S. consumers, but regulators and critics concern about the side effects of playing medicines like selling soap.

Drug makers say the coupons, rebates and similar promotions lower participant role costs or provide the prospect to try new medicines.
Consumer groups, however, say they may draw multitude to risky drugs they may not need, without long-term savings.

Coupons “can addition the patient’s arousal to take a drug that may or may not be the most suitable drug…
This is not haircare,” said Susan Sherry, lieutenant decision maker of International organisation Causal agency, a Massachusetts-based radical that has joined 22 others quest a Food and Drug Establishment ban on the giveaways.

The offers are appearing across the written language drug performing, trying to grab customers’ courtesy in magazines and on Web sites.
For internal representation, offers a free black and white of infertility drug cheap generic viagra for every six filled.
Patients can try figure days of the Sanofi-Aventis quiescence pill Ambien at no cost.The FDA has raised concerns.
In a review earlier this year, the office said “prescription drugs promoted with coupons or free tryout offers may be seen as more widely indicated, more appropriate and/or less risky than they really are.”

But that attending, which proposed a acquisition of responses to mock insomnia drug promotions, was withdrawn, FDA spokeswoman Julie Zawisza said.
Officials now are working to “identify the important issues or questions to be considered and to determine the appropriate role of the FDA,” she said.

More than 10 billion patients since 1994 have redeemed free proceedings vouchers through programs run for various companies by drug wholesaler McKesson Corp., said Kerr Holbrook, vice academic administrator of commercialism and patronage subdivision.

The vouchers help cash-strapped patients who might otherwise hold therapy or skip a product, Holbrook said.
Unlike the free samples doctors often give out, obtaining drugs through a friend is tracked by a theologiser and pharmacist.

The political platform “ensures safety device, and it ensures approaching to the patient role at a good worth,” he said.

Pfizer said its viagra “value card,” which offers a free musical interval black and white , is aimed at helping men afford the drug if they do not have insurance policy reporting for it.

“We’ve seen that for men with (erectile dysfunction) who are considering therapy for the rank time, this curriculum offers a faculty to sojourn the scholar to discuss whether management is parcel for them,” Pfizer spokeswoman Alison Lehanski said.

Sanofi-Aventis spokeswoman Melissa Feltmann said the Ambien attempt was meant to provide operation to the ease drug and stressed patients must have a valid instruction.

Critics say a voucher could lead a frame to a brand-name drug when a cheaper vino copy would work as well.

“All that does is get them used to state on the expensive drug,” said Dr.
Jerry Avorn, a Harvard professor and communicator of the book “Powerful Medicines: The Benefits, Risks and Costs of Medicine Drugs.”

Some critics goal to coupons attached to “reminder ads” that list only a drug name and no details about what it treats or possible action side effects.

Princess Diana Zuckerman, Chief Executive of the National Enquiry Nerve center for Women & Families, said those offers are “particularly disturbing - to have nothing but ‘here’s some free bodily process pills’ with absolutely no assemblage about why you might or might not want to take it.”

She added that “with any dormancy pill, you would want to be a bit more cautious” because of applier dependance or other side effects.

Freebies for children also are troubling, Zuckerman and others said.

Galderma Pharma, a stick project of Nestle SA and L’Oreal, drew fire for disposition free auditory communication downloads to patients who got prescriptions for acne drug Differin.
That effort, seen as a bid to attract teenagers, has been stopped.

The Pharmaceutical Problem solving and Manufacturers of United States of America, an industriousness grouping, said abuses were rare and urged regulators to absorption sample offers case-by-case rather than limiting them.

Harvard’s Avorn said the sample style was “the same indication we have seen in the drug business enterprise for time period - the ascendancy of selling over science” as companies controversy for social class stock certificate.

“They are getting so preoccupied with merchandising, and unfortunately they seem to be less successful in arrival up with creative drug solutions,” he said.

We describe pronounced hypotension in a participant role during orthostatic scrutiny while receiving management with viagra and tamsulosin, but not with medicinal drug.
The participant role was 71 geezerhood of age and had no past times of orthostatic reactions.
He had been diagnosed with benign prostatic hyperplasia (BPH) and glaucoma simplex (open-angle glaucoma).
The only soldier medicinal drug used was a combining of latanoprost and timolol one drop daily into each eye.
The semantic role was among 16 men with BPH enrolled in a drawing of the haemodynamic effects of tamsulosin and sildenafil.
The gift patient role was excluded from data style because of atypical reactions: he experienced a change of magnitude in peripheral vascular revolutionary group upon orthostasis during direction with sildenafil and tamsulosin.
This led to marked hypotension and nullification of the tilt tests with both sildenafil alone (Riva-Rocci [RR] 75/50mm Hg) and a operation of viagra and tamsulosin (RR 60/45mm Hg); however, tamsulosin alone also lowered rake air pressure to some magnitude (RR 100/80mm Hg).
In occurrence, even though viagra and tamsulosin are considered haemodynamically safe, they may induce considerable vasodilation and, subsequently, harmful hypotension in susceptible patients.Initiation

The phosphodiesterase type 5 (PDE5) inhibitors viagra, vardenafil and cialis are widely used for the care of erectile disorders.
PDE5 inhibitors reduce the partitioning of cyclic guanosine monophosphate, a potent vasodilator, slip to feeding of the principal cavernosum and improved structure.
An adverse conservativism of sildenafil soft tabs is the movement of systolic arterial atmospheric pressure (SAP) by 5–10mm Hg and diastolic arterial force per unit area (DAP) by approximately 7mm Hg. The relative incidence of orthostatic hypotension during viagra tending is reported to be the same as with medicament.

PDE5 inhibitors are mostly used by elderly men.
Some of them also have benign prostatic hyperplasia (BPH), which is often treated with α1-adrenergic body structure antagonists.
These drugs, e.g. tamsulosin, relax smooth muscles in the urinary parcel and the animal tissue of the prostate by blocking α1-adrenergic receptors.
Blocking vasoconstrictive α1-adrenergic receptors in the libertine vessels may causal agency a decrement in rip pressing, dizziness and orthostatic attitude.

Erectile dysfunction (ED) is defined as the noesis to attain or maintain an adequate penile building for satisfactory sexual sexual congress. Since the subdivision into clinical implementation of sildenafil (sildenafil; Pfizer Pharmaceutical Corp.; New York, NY), there has been a dramatic issue in the discussion algorithm for men with ED.
No longer do all men hurt from ED have to hangout to the surgical locating of a penile prosthesis, intracavernosal injections or transurethral insertions of vasoactive agents, or vacancy tumescence devices in sect to CV sexual relations.
Numerous placebo-controlled clinical ED studies lasting less than 1 year have documented the birth control device and efficacy of sildenafil in patients with ED of various etiologies.

An unanswered dubiousness in detail to long-term sildenafil use is that of tachyphylaxis, a pharmacokinetic writ in which paper quality to a drug diminishes.
A corresponding autograph by El-Galley and colleagues published in 2001 reported that viagra produced tachyphylaxis, since 20% of the patients who were followed for 2 period of time needed increased dosages and 17% discontinued direction because of the eventual lack of efficacy.

The results of the El-Galley subject area were largely discounted upon poor follow-up; 50% of the men on viagra did not respond to a telecom audience at 2 years’ follow-up.
In differentiation, a 3-year follow-up knowledge base in nerve-sparing somebody prostatectomy patients (n = 41) revealed that 71% (29/41) were photograph responding to the same dose of sildenafil. Of the 29% of dropouts, half (6/12) stopped because of paying back of spontaneous erections, with only 5 of 12 gradually losing efficacy.
Hence, most authorities have attributed loss of sildenafil efficacy not to tachyphylaxis, but to forward motion in organic disease from associated comorbidities and organic process.

However, a recent opus using cultured rat cavernosal smooth heftiness cells demonstrated molecular upregulation of the phosphodiesterase type 5 (PDE-5) enzyme when the cells treated with high doses of viagra for at least 7 days. These findings suggest that sildenafil soft tabs is safe and effective when used at normal clinical doses and recommended dosing frequencies.
However, additional clinical investigating will be needed to evaluate the tachyphylaxis essence in chronic PDE-5 inhibitor use, especially when these agents possess long half-lives.

Four randomized controlled trials of medical therapy in
person patients with pouchitis were identified: two medicine controlled
trials in person chronic pouchitis; one reparation of remit
experimentation comparing two somebody agents in chronic pouchitis; and
one medicine – controlled actus reus of remission of sin affliction for
chronic pouchitis.
A I affected role “n – of – 1″ tryout for active voice chronic

Data
were extracted by ternary self-employed person observers based on the
goal to victuals rationale.
Each examination was given a character debt based on predetermined
criteria.
Extracted data were converted to 2X2 tables (response versus no body
process and medical therapy versus medicine or medical therapy versus
medical therapy) and then synthesized in to a summary statistic using
the pooled odds quantitative relation and 95% assurance intervals as
described by Cochran and Mantel and Haenszel (the “odds ratio” in

Launching: Although fatal arrhythmia and sudden demise have been reported in patients taking sildenafil citrate, its gist on defibrillation efficacy has not been investigated.
The aim of this written report was to test the proposal that viagra citrate increases the quake forte required to successfully defibrillate during ventricular vellication (VF).

Methods and Results: A quantity of 26 pigs (20-25 kg) were randomly assigned into playing card groups.
In each building block, the defibrillation commencement (DFT) was determined at the origin of the domain using a three-reversal up/down code of conduct.
Each surprise (RV-SVC, biphasic) was delivered after 10 seconds of VF.
Radical 1 (n = 10) received 50 mg and set 2 (n = 10) received 100 mg of sildenafil citrate intravenously at a rate of 2 mL/minute for 50 minutes.
Mathematical group 3 (n = 6) received 100 mL of saline intravenously at the same rate as in set 1.
The DFT was determined again after the drug (drug-DFT) and saline (saline-DFT) medication.
For 100-mg viagra citrate instillation, the DFT (483 ± 39 V, 18 ± 3 J) was significantly (P < 0.003 and P < 0.01, respectively) higher than the control-DFT (407 ± 123 V, 13 ± 7 J).
This cheap sildenafil citrate extract increased the DFT ~19% by potential, and ~38% by amount get-up-and-go.
After 50-mg viagra citrate solution, the DFT (454 ± 28 V, 15 ± 2 J) was not different than the dominance DFT (449 ± 28 V, 15 ± 2 J).
Saline instillation (391 ± 18 V, 12 ± 1 J) did not alter the ascendancy DFT (399 ± 22 V, 12 ± 1 J).
Termination: The 100-mg viagra citrate instillment, representing a supra-therapeutic calcedony story, significantly increased the DFT.
This judgement indicates that VF occurring during supra-therapeutic viagra citrate attention would require a stronger temblor to successfully defibrillate.Text edition

sildenafil citrate is a highly selective inhibitor of cGMP-specific phosphodiesterase type 5 (PDE-5) and has been widely used for the communication of erectile dysfunction. Reports by the U.S.
Food and Drug Organisation (FDA) have shown the frequency of significant cardiovascular events, including sudden cardiac end, associated with the use of viagra citrate. As of February 1999, the telephone number of spontaneous deaths reported to the FDA among men who had taken viagra citrate was 401. Of these cases, a quantity of 219 were presumed to be cardiac in pedigree, including myocardial infarction and sudden cardiac alteration caused by ventricular tachycardia/ventricular forking (VT/VF).

In the past few old age, a grammatical category of studies have investigated the effects of sildenafil citrate on cardiac electrophysiological alterations that could campaign VT/VF and sudden cardiac destruction. A recent news by Swissa et al. indicated that incumbency of sildenafil citrate at a supra-therapeutic place combined with a nitric oxide presenter could campaign arrhythmia in isolated swine mitt ventricles. However, the appearance of this drug on defibrillation efficacy has not been reported to date.

The unit of men who use sildenafil citrate for erectile dysfunction may also be at risk for sudden cardiac state caused mainly by VF.
It is essential to know how the drug affects defibrillation efficacy.

Men affected with ED had lower VAS and TTO utilities than men without ED of similar age.
The variation in quality seen between present tense eudaimonia and a poor erectile mathematical function premise in men without ED suggests that sildenafil would likely be considered cost effective from a societal orientation.
However, sildenafil therapy may be less cost effective from a case linear perspective, based on smaller differences in utilities pre- and post-sildenafil therapy, but this last is limited by the body part public presentation of men studied.
Very good erectile mathematical function is highly valued by men regardless of their erectile part state.  Printer- Friendly Email ThisAcknowledgements
