From a computerized database comprising 28 pertinent items in each of a consecutive series of 664 patients with cholelithiasis, differences were studied between men and women. In 52 patients there was a documented attack of acute pancreatitis (7.8%). Twenty-five of 174 men had pancreatitis, compared with 27 of 490 women (p less than 0.0001). Men developed gallstones later in life than women, but suffered gallstone pancreatitis earlier in life and in the course of their gallstone-related disease. A history of flatulent dyspepsia, chronic cholecystitis, and biliary colic was less common in men than in women with pancreatitis (p less than 0.0001). Men with pancreatitis had fewer stones in their gallbladders than did women (p = 0.0002). The cystic duct and the common bile duct in the pancreatitic patient were more likely to be dilated (p less than 0.0001). In the nonpancreatic group, these ducts were larger in men. Pancreatic duct reflux on operative cholangiography was more common both in patients with pancreatitis 62% cf 14% (p less than 0.0001), and in men (p less than 0.001). Predisposition to pancreatitis relates to duct size rather than stone size per se. Men are more susceptible to gallstone migration at an early stage of their disease. In addition they have a larger diameter duct system and possibly a different anatomic disposition of the sphincter of Oddi, which predisposes them to a higher incidence of pancreatitis than women. The data suggest that it is cystic duct size that is critical in the pathogenesis of gallstone pancreatitis.

Ulcer-like epigastric symptoms constitute the most common presentation in acute abdominal complaints. A prospective study of such patients attending a surgical emergency unit is presented. Among the patients with dyspepsia, the numbers per thousand population varied between different parts of the city from 0 to 45. Most of the patients with dyspepsia were seen early in the week. Men, unmarried persons and immigrants were overrepresented in the dyspepsia group, and the relative figures for low educational status, history of alcohol abuse and smoking were higher than expected from city averages. Sick-listing during the preceding year exceeded 90 days in 17% of this group. The observed associations indicated the advisability of preventive measures.

The value of insulin and augmented histamine tests in predicting recurrence of duodenal ulcer within six to eight years after truncal vagotomy and drainage was assessed in a series of 500 consecutively and electively operated patients. Criteria of recurrence were established by a discriminative analysis of gastric acid secretion parameters. Recurrence was predicted with a probability of about 75% in patients with dyspepsia, the proportion between recurrences and dyspeptic nonrecurrences being 1:1. The discriminatory ability of the insulin test was no better than that of the postoperative histamine test. Men with a preoperative PAO > 46.1 m-equiv/h had a risk of recurrence of 21%, women with a PAO > 41.5 m-equiv/h, 28%. Below these levels the risk was 5 and 1% respectively, demonstrating that recurrence after vagotomy is related to the number of parietal cells before vagotomy. A rationale is provided for antrectomy and vagotomy in duodenal ulcer patients with a high number of parietal cells.

One thousand five hundred and eighty-three patients who were x-rayed for dyspepsia showed varioliform erosions in 15.3%. Men had an incidence of 9.8%, almost twice as common as in women (5.5%). Mucosal polyps, usually of the hyperplastic type, occurred in 2.4%. 15% of patients with gastric ulcers and 16% of patients with duodenal ulcers had varioliform erosions. On the other hand, amongst patients with erosions, 11% had gastric ulcers and 8.3% duodenal ulcers. The definitions of erosion which have been given in the literature are partly contradictory, and are discussed. Varioliform erosions, also known as complete erosions, may be acute or chronic. They are the third most common cause of bleeding from the upper gastrointestinal tract. With modern radiological methods of examining the stomach, they are no longer a rare finding.

The efficacy and safety of oral sildenafil citrate for the treatment of erectile dysfunction (ED) were assessed in a 12-week placebo-controlled study. Men with ED of organic, psychogenic, or mixed aetiology were randomised to placebo (n = 166) or 50 mg sildenafil (n = 163), with adjustment to 100 mg or 25 mg based on efficacy and tolerability. Efficacy assessments included a global efficacy question, event log data, and an optional partner questionnaire. At the end of the study, improved erections were reported by 74% of patients receiving sildenafil versus 16% for placebo (p < 0.0001). In the final 4 weeks of treatment, 65% of all attempts at sexual intercourse were successful for all patients (responders and non-responders) receiving sildenafil versus 20% for placebo (p < 0.001). The mean number of successful attempts per month was 5.9 for patients receiving sildenafil versus 1.5 for those receiving placebo (p < 0.0001). The most common adverse events--headache, flushing, and dyspepsia--were generally mild to moderate in nature and rarely (< 1%) a reason for discontinuation of treatment. Oral sildenafil is an effective, reliable and well-tolerated treatment for ED of organic, psychogenic or mixed aetiology.

Sildenafil citrate (Viagra) has been shown to be an effective treatment for erectile dysfunction (ED) of organic aetiology. This study assessed the efficacy and tolerability of sildenafil for treating ED of psychogenic and mixed psychogenic/organic aetiology. Men with ED of psychogenic and mixed aetiology were randomised in a double-blind, fixed-dose study to placebo (n = 95) or sildenafil 10 mg (n = 90), 25 mg (n = 85), or 50 mg (n = 81) once daily for 28 days. Efficacy was evaluated with two global efficacy questions, a patient log of erectile activity, a sexual function questionnaire and a partner questionnaire. Patients receiving sildenafil had significantly more grade 3 (hard enough for penetration) or grade 4 (fully hard) erections per week than patients receiving placebo, and a greater proportion of patients receiving sildenafil reported that treatment had improved their erections (p < 0.001). Results of the sexual function questionnaire demonstrated significant improvement for patients with ED receiving sildenafil compared with patients receiving placebo for frequency, hardness and duration of erections (p < 0.01), and for enjoyment of sexual intercourse and satisfaction with sex life (p < 0.05). The results of the partner questionnaire were consistent with the results reported by patients and showed that treatment with sildenafil was associated with significant improvement in the partners' own sex lives (p < 0.001). Adverse events were mostly mild to moderate in nature. The commonest adverse events were headache, dyspepsia, flushing, myalgia, arthralgia and flu syndrome. Discontinuations due to treatment-related adverse events were few, ranging from 1.1% to 6.2% for patients receiving different doses of sildenafil and 4.2% for patients receiving placebo. Sildenafil is an effective and well-tolerated treatment for ED of psychogenic or mixed aetiology with once-daily dosing.

Evidence has begun to accumulate that suggests there may be gender differences in the presenting symptoms of acute coronary syndromes (ACS). Identification of gender differences has implications for both health care providers and the general public. Women should be instructed as to the symptoms expected with ACS on the basis of evidence obtained from studies that include both sexes. Twelve studies that identified symptoms of ACS for both women and men were identified through a review of the literature. In several of the studies, which included all types of ACS, women had significantly more back and jaw pain, nausea and/or vomiting, dyspnea, indigestion, and palpitations. In a number of the studies, which solely sampled patients with acute myocardial infarction, women demonstrated more back, jaw, and neck pain; nausea and/or vomiting; dyspnea; palpitations; indigestion; dizziness; fatigue; loss of appetite; and syncope. Men reported more chest pain and diaphoresis in the myocardial infarction sample. Results of these studies showed that women and men experienced the same symptoms with ACS. However, in some studies there were gender differences in the proportion of symptoms. Given the current state of the science, definitive conclusions regarding gender differences in the symptoms of ACS cannot be drawn. Further study is urgently needed to clarify and expand on these findings.

Cigarette smoking is associated with increased risk of stomach cancer in many studies but there are limited data on this relationship in women and on risk associated with use of tobacco products other than cigarettes. We examined stomach cancer death rates in relation to cigarette smoking in women and use of cigarette, cigar, pipe, or smokeless tobacco in men in a nationwide prospective mortality study in the United States (US). Cohort follow-up from 1982-96 identified 996 and 509 stomach cancer deaths among 467,788 men and 588,053 women, respectively. Cox proportional hazards models were fitted to estimate rate ratios (RR) and 95% confidence intervals (CI) using non-users of tobacco as the referent group. Multivariate-adjusted RRs were the highest for men who currently smoked cigars (RR = 2.29, 95% CI = 1.49-3.51) or cigarettes (RR = 2.16, 95% CI = 1.75-2.67) and both increased with smoking duration. Women who currently (RR = 1.49, 95% CI = 1.18-1.88) or formerly (RR = 1.36, 95% CI = 1.08-1.71) smoked cigarettes were at significantly increased risk, as were men who formerly smoked cigarettes (RR = 1.55, 95% CI = 1.28-1.88), or currently (RR = 1.81, 95% CI = 1.40-2.35) or formerly (RR: 1.57, 95% CI = 1.22-2.03) used more than one type of tobacco. Men who reported a history of chronic indigestion or gastroduodenal ulcer had substantially higher mortality rates associated with current cigarette (RR = 3.45, 95% CI = 2.05-5.80) or cigar (RR = 8.93, 95% CI = 4.02-19.90) smoking, as did men who were current aspirin users. If causal, the estimated proportion of stomach cancer deaths attributable to tobacco use would be 28% in US men and 14% in women. We conclude that prolonged use of tobacco products is associated with increased stomach cancer mortality in men and women. The accumulated evidence from this and other studies support reconsidering stomach cancer as a tobacco-related cancer.

The efficacy of sildenafil citrate (Viagra), an oral agent for the treatment of erectile dysfunction (ED), has been demonstrated in global studies. This 12-week randomized, double-blind, placebo-controlled, parallel-group, flexible-dose study assessed the efficacy and safety of sildenafil to treat ED in men in Egypt and South Africa. Men with ED of varied etiology were randomized to receive sildenafil 50 mg (n=128) or placebo (n=126); doses could be adjusted to 100 or 25 mg. Questions from the International Index of Erectile Function (IIEF) assessing the ability to achieve (Q3) and maintain (Q4) erections demonstrated a significant improvement with sildenafil compared with placebo (P<0.0001). Improved erections were reported by 74% of patients receiving sildenafil and 27% of those receiving placebo (P<0.0001). Headache, dyspepsia, and flushing were the most common adverse events in sildenafil-treated patients. These results are consistent with clinical trials in other countries. We conclude that sildenafil is an efficacious and well-tolerated treatment for men with ED in Egypt and South Africa.

Advances in molecular biology and protein chemistry, along with increasing understanding of the mechanisms of penile erection, have spurred development of pharmacologic approaches to the treatment of erectile dysfunction (ED). The next generation of oral agents includes tadalafil, a potent, highly selective phosphodiesterase 5 inhibitor. In vitro studies have shown that tadalafil enhances relaxation of trabecular smooth muscle, and clinical trials have supported its efficacy and tolerability in a broad population of men with ED. The effect of tadalafil in enhancing the erectile response to sexual stimulation is relatively rapid in onset and lasts for >or=24 hours. The ability of patients with ED treated with tadalafil to achieve improved erectile function is demonstrated by significantly increased subjective measures of penetration ability, successful intercourse, and sexual satisfaction. Partners have expressed similar or higher levels of satisfaction with the results of treatment. Men with ED of psychogenic, organic, or mixed etiology and in a range from mild to severe have experienced significant improvment with tadalafil treatment. Response to treatment in men with diabetes has been robust and not affected by disease severity. Tadalafil has been well tolerated. Adverse events have generally been mild or moderate and have abated with continued treatment. Headache and dyspepsia have been most frequently reported. Changes in color vision have been rare (<0.1%) with tadalafil across all clinical trials. Tadalafil appears to be a safe and effective treatment for men with ED.
