The occurrence of specific adverse events involving visual disturbances viagra 100 mg amex, including blurry 79-84 purchase viagra 75 mg,86,88,90,91,94,95,97,98,107,109,115, 122,125,126,131,135, vision and chromatopsia, were reported in 33 trials. These events were numerically more frequent in participants treated with sildenafil, ranging from 94 97 101 97 3 percent to 29 percent, compared with the range of 0 percent to 12 percent for placebo- treated participants. In the majority of these trials, the rate for withdrawals due to adverse events in placebo-treated participants ranged between 2 and 8. The specific events leading to withdrawals were 88,101,109,137,142,151 86,88,137 headache, nausea, vomiting, gastrointestinal symptoms, visual 88,165 87,89,99,101,165,166 166 101 disturbances, cardiovascular events, urinary tract infection, chest pain, 160 and cerebrovascular events. These events were reported for participants treated with sildenafil, 89 with the exception of one case of myocardial infarction and one case of urinary tract 166 infection in placebo-treated participants. In 29 trials, no 78,80,81,85,90,91,98,99,101,105,108,110-112, 124,125,128,131,133,134, patient experienced any serious adverse event. In general, the quality of reporting 82, serious adverse events was poor, and some studies did not provide a full description of events. For the 95,96 remaining 27 participants in two trials, the treatment group designation was not reported. These included 83 myocardial infarctions, which occurred in one participant taking sildenafil, two participants 89,126 96 taking placebo, and one participant whose group designation was unknown. Severe angina 33 87 pectoris occurred in a participant taking 100 mg sildenafil and in another patient taking 84 placebo. Heart failure, atrial fibrillation, and arrhythmia occurred in two participants taking 143 143,160 sildenafil. Cerebrovascular events occurred in two participants taking sildenafil, one of 160 which was taking 100 mg of sildenafil. Respiratory events included pneumococcal pneumonia 143 143 in one participant on placebo and pulmonary edema in another participant on sildenafil. Accidental injuries were reported in two participants, one severe vertebral fracture in a 83 87 participant taking sildenafil, and the other a hand injury in a participant taking placebo. Four of the eight deaths occurred in placebo groups, one resulting from 126 123,171 myocardial infarction. Two 123 deaths occurred in participants treated with sildenafil; one of these resulted from an accident, 88 and the other from cardiac arrest. For more details on serious adverse events in each trial, please refer to Table 10. Similarly, two other trials showed that participants treaded with sildenafil compared with those on placebo, experienced a significantly greater mean number of erections (grade 3–4) per month. Five trials indicated a statistically significant longer mean duration of erections (≥60 percent rigidity) for participants treated with sildenafil compared with those who received placebo. The results of analyses provided for these trials did not reveal any treatment effect modification by the above-mentioned factors. Additionally, two other trials examined and compared two different dosage regimens of sildenafil (i. In one trial, which reported the incidence of any adverse events, specifically, events in >5 percent of participants in one or more treatment groups, the proportions of participants experiencing at least one adverse event (due to all causes) in either the sildenafil 25 mg, 50 mg, and 100 mg treatment groups were 49, 61, and 72 percent, respectively. The 86 corresponding dose-specific proportions observed in another trial, a were 32, 69, and 86 percent, respectively. Both trials indicated a numerically increasing trend in the incidence of any 96 adverse events observed with the higher dose of sildenafil. None of these three trials reported any 35 85,93 statistical test results for the observed between-treatment differences. In two trials, the number of participants with treatment-related adverse events did not differ across the 25 mg and 78,85,86, 93,96,137 50 mg sildenafil treatment groups. Of the events observed across the trials, headache, myalgia, nausea, dyspepsia, and flushing were the most frequently experienced and were mild to moderate or transient in nature. These trials compared 93 96 25 mg to 50 mg, and 10 mg to 25 mg and 50 mg of sildenafil. There were three other instances of serious adverse events (myocardial infarction, renal cell carcinoma, and epileptic crisis) in one 96 trial. The group designation of the participants experiencing these events were not reported. The rate of 85 96 discontinuation ranged from 0 percent to 3 percent for the 10 mg dose of sildenafil, from 0 137 93,96 85 96 percent to 4. Safety data was not reported for the trial that compared different timing of sildenafil (100 161 157 mg) administration in relation to food and sexual activity. In the trial comparing "nightly" (50 mg) and "as needed" (50 mg to 100 mg) sildenafil dosing regimens, the proportion of withdrawals due to adverse events was similar across the two groups (approximately 7 percent). Overall, more participants experienced adverse events (headache, flushing, dyspepsia, and rhinitis) in the "as needed" compared with the "nightly" group. Reportedly, none of the participants in this trial 157 developed a serious adverse event. All six trials assessing the efficacy of different doses of sildenafil monotherapy (10 mg, 25 mg, 50 mg, and 100 mg), demonstrated a dose-response trend for sildenafil toward improving erectile function. Although none of these trials provided a formal statistical test for the observed between-arm (sildenafil versus placebo) differences, the degree of improvement tended to increase numerically with a higher dose of sildenafil. In two trials, the corresponding proportion of participants who received 100 mg sildenafil ranged from 84 to 88 78,86 percent. In two other trials the participants’ mean duration of penile rigidity (>80 percent and >60 percent, respectively) in minutes at the base and the tip of the penis was shown to increase numerically with higher doses of sildenafil (10 mg versus 25 mg versus 100 85 mg).
In these studies generic 100mg viagra, except for one conducted in 72 Egypt purchase viagra 50mg visa, the prevalence of hyperprolactinemia ranged from 1. These studies used similar cut-off points to define a positive or negative test result (Table 7). The cut-off values used to define a positive/negative test result were provided for two studies only (Tables 8 and 9). Prevalence of Hypogonadism and Hyperprolactinemia by Age We descriptively examined patients’ age distribution (mean and range) in individual studies to determine whether age could account for the between-study differences in the reported prevalence rates of hypogonadism and hyperprolactinemia. The results did not reveal any numerical trends between the age distribution and the prevalence rates. All three studies indicated higher prevalence of hypogonadism in men aged 50 years or older compared with those under 50 years of age. The Efficacy of Hormonal Therapy in Treating Erectile Dysfunction in Patients with Hormonal Abnormalities Overview of Trials Two studies were identified and were judged to be eligible to address the present question.

Sharma 2006 , and Salonia 2007 29 Overview of Trials 79-84,86-88,90,91,94-98,101,104,106, 107,109 Of the 73 trials, 52 (71 percent) used a parallel-arm design, 112,115,122-126,128,133,135,138,142,143,147,151,155-158,160,162,166,167,169,171,173,175,176 while the remaining 21 used 78,85,89,93,99,102,105,108,130-132,134,146,149,150,161,164,165,168 a crossover design. Two Italian trials were supported by Sigma 104,112 88,106,111,123,130,134, 149,150,155 Tau. Three 101,157,162 102,105, trials had no source of support, and five other trials reported other funding sources. The total and mean numbers of patients randomized across the 73 trials were 11,064 and 152, respectively. The 85,169 147 number of randomized patients across all trials ranged from 12 to 568. The most common reported reasons for the trial exclusion were the presence or history of penile/testicular deformity, cardiovascular disease, stroke, myocardial infarction, use of nitrates, any major hepatic or renal disease, spinal cord injury, retinitis pigmentosa, diabetes, major psychiatric disorder, alcohol/drug abuse or hypotension. In one trial, the participants’ age ranged between 19 and 35 years, and in two trials this range was from 35 to 70 130 160,175 years. Depending on the observed efficacy and tolerability of sildenafil, the daily dose was flexible (upward or downward titrations: 50 mg – 25 mg – 100 mg) in more than half of the included 79-84,87-91,94,95,97-99,107-109,115, 124-126,128,131,133,135,138,142,143,147,150,151,156,157,160,162,164-168,171 trials. In one trial, participants were randomly assigned to receive 100 mg/d of sildenafil either 1 hour before/during a meal or 30–60 minutes before sexual activity. Participants in another trial were randomly assigned to receive either fixed 157 dosing (50 mg every night) or flexible dosing (50 mg or 100 mg, as needed) of sildenafil. In five trials, patients received either mono (or combined) therapy of sildenafil or 106,124,132,155,173 106 monotherapy of another active treatment. Of the 73 trials, 66 (91 percent) were placebo-controlled (with or without an active treatment 78-91,93-99,101,102,104,105,107-111,115,122,123,125,126,128,130-135,137,138,142,143,146,147,149,151, 156,158,160-162,164-169, arm), 171,175 106,112,124,150,155,157,173 and the remaining seven trials had no placebo arm. Study and Reporting Quality The mean of Jadad total score for the 73 trials was 3. The Jadad total score for the 99,124,132,150,178,179 81,91,94,95,115,123,128,143,162,168 individual trials ranged from 1 to 5. The method for 81,84,89,91,94,95,99,101,104,106, generating the sequence of randomization was described in only 26 trials, 107,109,112,115,123,128,143,155-157,162,164,165,167,168,171 89,99,104,112 and in four of these the method was determined to be inappropriate. Of the 64 double-blind trials, 42 (66 percent) reported 79-83,86-91,94,95,97,98,102,104,107,108,112,115,122,123,125,128, 30, some description of the blinding methods. The methods used to conceal the treatment allocation for the remaining 61 trials could not be ascertained (i. For the remaining 13 78,93,99,102,105,108,130,131,134,149, 161, trials, it was not clear whether any washout periods were applied. In four placebo-controlled 158, 161,162,169 trials the efficacy and safety profiles of sildenafil and placebo were not compared (see sildenafil dose/dosage one versus dose/dosage two and sildenafil mono versus sildenafil in combination sections). Thus, results provided here are based on data obtained from 62 placebo- 78-91,93-99,101,102,104,105,107-111,115,122,123,125,126, 128,130 controlled trials. In the majority of the placebo-controlled trials, the proportion of patients with at least one adverse event was greater either numerically or with statistical significance for participants taking sildenafil compared with those taking placebo. The most commonly observed all-cause adverse events across the trials were headache, flushing, and dyspepsia. Other adverse events were myalgia, rhinitis, cardiovascular events, flu- like symptoms, nausea, respiratory events, diarrhea, vomiting, dizziness, chest pain, urinary tract infections, depression, and anxiety. Overall, these events were less frequent for participants taking placebo compared with those taking sildenafil. These effects were usually of a mild to moderate or transient nature not requiring discontinuation of the therapy. The occurrence of specific adverse events involving visual disturbances, including blurry 79-84,86,88,90,91,94,95,97,98,107,109,115, 122,125,126,131,135, vision and chromatopsia, were reported in 33 trials. These events were numerically more frequent in participants treated with sildenafil, ranging from 94 97 101 97 3 percent to 29 percent, compared with the range of 0 percent to 12 percent for placebo- treated participants.

This incident increases every year by 10 buy viagra 50 mg with amex,000 to 12,000 new patients (Harrop et al. In Canada, about 36,000 people live with spinal cord injuries, while 55% of them, are people in the reproductive phase of their life, aged 16-30 years, and the ratio of men to women is calculated to 4 /1(Mittmann et al. For several years there was a myth in societies that people with paraplegia or quadriplegia have no sexuality, do not have erectile function and that they are infertile. In fact, sexual expression is a component of personality and it is independent to the erectile function or fertility status. In handicaps lack of sexual interest is associated with social withdrawal and inability to recover while sexual alertness is associated with faster and better recovery. The degree of sexual rehabilitation is directly related to physical rehabilitation, social integration and quality of life (Biering-Sorensen & Sonksen, 2001; Fisher et al. Last years the medical community emphasizes on quality of life and sexuality of people with spinal cord injuries. It is shown that the 66% of patients with spinal cord injuries consider their erection sufficient for sexual activity. Sensory data from the eyes and skin are relayed to certain areas within the hypothalamus where appropriate signals are relayed to the penis. The upper centers which regulate the erectile function in the brain are located at the cortex and the hypothalamus, as mentioned above. The main involved nuclei are: paraventicular nucleus, medial preoptic area, paragigantocellular nucleus, and locus coeruleus. These centers are two: the psychogenic, sympathetic erection center which is located at the Th11-12 until L2-3 level of spinal cord and the reflexogenic, parasympathetic erection center which is located at the S2-4 level of spinal cord. The sympathetic erection center is purely autonomous, contains fibers with evoked and others with inhibitory action and travels with the inferior hypogastric plexus. The afferent fibers are coming from the pudendal nerve and the dorsal penile nerve, while the efferent fibers involve in the formation of the cavernous nerves and the inferior hypogastric and sacral plexus. The two centers of the spinal cord are under the control of the brain (Saenz de Tejada et al. Erection can be distinguished to reflective and psychogenic according to the origin of its induction and the erection center which is mainly involved. Reflective erection is the outcome of somatoaesthetic stimulation and may be independent of sexual arousal. This erection takes place through the reflexogenic, parasympathetic erection center. Psychogenic erection, which predominates in humans, is the result of sexual desire caused by images, fantasies and thoughts related to previous sexual experiences. The psychogenic, sympathetic erection center is mainly responsible for this kind of erection. In patients with upper cord lesions, reflexogenic erections are preserved in 95% of them, while in patients with complete lower cord damages this rate is only 25%. The quality of erection is better as higher the lesion is located (Eardley & Kirby, 1991). The preservation of the sacral parasympathetic neurons leads to the maintenance of reflexogenic erection. In case of sacral injury thoracolumbar pathway may take over through synaptic connections. In general, men with cervical and thoracic lesions regain their erections sooner and better than men with lumbar lesions (Courtois et al. Manipulations such as rubbing of the thighs or nipples, squeezing of the glans, suprapubic percussion, irritation of the anal region, proved to be more effective than masturbation or any other stimulation of the genitalia (Saenz de Tejada et al. Lesions higher to Th11 level are combined with erection of both corpora cavernosum and corpus spongiosum, while lesions below this level exclude the participation in the erection of the corpus spongiosum (Biering-Sorensen & Sonksen, 2001). The reflexive erections maintain in 95% of patients with total damage over the sacral center, while in lower level lesions this percentage is up to 25%. The training for the challenge of this reflex is part of the sexual rehabilitation. Psychogenic erections have been observed in 60% of patients with intact sympathetic erectile center (Th11-L2) and lesion below the L2 level. Psychogenic erections, as mentioned above, are independent from direct physical stimulation and are the result of visual or acoustic stimuli, dreams, fantasies or memories. Objectively, it is more of a swelling of the penis rather than a hard erection, rarely allowing penetration (Derry et al. These erections onset after a psychic stimulus and maintain or even are enhanced by a physical stimulus, or they are prolonged reflecting erections which are enhanced by a strong sexual desire. The comparison between the erections of quadriplegic and paraplegic patients showed that quadriplegic men had better erections (regarding hardness and duration) than paraplegic patients. Additionally, thoracic spinal lesion was associated with poor nocturnal erections comparing with cervical spinal injuries (Suh et al. Patients with lesions above the Th6 level often present the phenomenon of autonomous dysreflexia, which involves reflecting increased sympathetic tone at the level below the lesion. At the levels higher to the spinal lesion, vasodilatation takes place and causes flashing and headache. The more serious symptom is the parasympathetic activation which decreases the heart rate. This situation with excessive hypertension and bradycardia is dangerous for the patient and it was found that sexual arousal may trigger dysreflexia. The absence or presence of erections, under what circumstances they took place, the number and the frequency of them, the quality of erections (regarding hardness and duration) compared with the erectile function before injury and the frequency of sexual intercourse, are some of the questions which have to be answered.
