[Constipation in postmenopausal women].

OBJECTIVES: To investigate the prevalence and factors associated with constipation in postmenopausal women and evaluate the level of agreement between different diagnostic criteria. METHODS: A cross-sectional study was conducted with 100 postmenopausal women more than 45 old. The Rome II criteria, stool frequency per week and patient self-evaluation were the diagnostic criteria applied. Social demographic and clinical characteristics with their descriptive analysis were assessed. Subsequently, kappa (ê) statistics was used to assess the level of agreement between diagnostic criteria. The association between constipation and its possible determinants was studied by bivariate and multivariate analyses, using the prevalence ratio (PR). The confidence interval was set at 95% (95% CI). RESULTS: The mean age of participants was 58.9+/-5.9 years (range, 46-76 years). The prevalence of constipation was 47%, 37% and 26%, according to patient self-evaluation, the Rome II criteria and < 3 bowel movements per week, respectively. The best agreement found was between patient self-evaluation and the Rome II criteria (k: 0.63; 95% CI: 0.48-0.78). After multivariate analysis, the history of perianal surgery (PR: 2.69; 95% CI: 1.03-7.01), according to the Rome II criteria; the presence of hemorrhoids, according to stool frequency (PR: 2.53; 95% CI: 1.16-5.51) and patient self-evaluation (PR: 1.78; 95% CI: 1.01-3.15) were associated with constipation. CONCLUSIONS: Prevalence of constipation in postmenopausal women was high. Agreement between diagnostic criteria ranged from moderate to good. History of perianal surgery and presence of hemorrhoids were associated with constipation.

Comparison of tests for fecal lactoferrin and fecal occult blood for colorectal diseases: a prospective pilot study.

OBJECTIVE: This prospective pilot study was conducted to compare the usefulness of measuring fecal lactoferrin (Lf) to that of fecal occult blood (FOB) test for detection of colorectal diseases. PATIENTS AND METHODS: The subjects were 351 patients who underwent colonoscopy. A fecal sample was obtained on the day before colonoscopy. Fecal Lf was measured by enzyme-linked immunosorbent assay. The FOB test was performed by combined assay (latex agglutination) of hemoglobin and transferrin. RESULTS: The specificities of the fecal Lf and FOB tests were the same (88.7%). For patients with colorectal cancer (13), colorectal polyp (69), ulcerative colitis (18), Crohn's disease (13), non-specific colitis (8), internal hemorrhoids (60), colon diverticulum (27), and miscellaneous diseases of the colon (10), the rates of positivity for fecal Lf were 7/13, 14/69, 12/18, 7/13, 4/8, 22/60, 8/27, and 6/10, respectively. The corresponding rates for FOB were 8/13, 12/69, 11/18, 4/13, 4/8, 9/60, 2/27, and 1/10. For patients with internal hemorrhoids, the rate of positivity for fecal Lf was significantly higher than that for FOB. In other disease groups, there was no significant difference in the rate of positivity between fecal Lf and FOB. CONCLUSION: These findings suggest that measurement of fecal Lf is as useful as FOB in detecting colorectal diseases.

Diagnosis and treatment of acute lower gastrointestinal bleeding.

Diagnostic sigmoidoscopy and barium enema examinations (n = 214) or colonoscopy (n = 52) were performed for acute lower gastrointestinal (GI) bleeding. The cause of bleeding was detected in 76% (203 of 266) of the primary examinations, and the cause remained unclear after subsequent examinations in 17% of the cases. Hemorrhoids were the cause of bleeding in 28% (56 of 203) of the cases, colonic diverticular disease in 19% (39 of 203), adenomatous polyps in 11% (23 of 203), and colorectal cancer in 10% (20 of 203). The sources of bleeding did not differ significantly by sex. An anorectal site of bleeding was most often detected in patients less than 50 years of age (p < 0.0001) and a left colonic site in those more than 70 years (p < 0.0001). Hemorrhoids significantly more often caused rectal bleeding among the youngest patients (p < 0.0001) and colonic diverticular disease among the oldest patients (p < 0.0001) and colonic diverticular disease among the oldest patients (p < 0.0001) than among the others. Of the 266 patients, 19% have been operated on for the bleeding lesion. The mortality related to lower GI bleeding was 4% (11 of 266). The mean age of the patients who died was higher than that of those who survived (p < 0.05).

[An elderly case of idiopathic thrombocytopenic purpura associated with acute myocardial infarction].

We report a rare case of idiopathic thrombocytopenic purpura (ITP) associated with acute myocardial infarction (AMI). A 72-year-old woman with hypertension and hemorrhoids was admitted because of chest pain, severe anemia (RBC 340 x 10(4)/microliter, Hb 5.4 g/dl, Ht 21.7%) and thrombocytopenia (0.2 x 10(4)/microliter). AMI was diagnosed by electrocardiogram (ST elevation and negative T in V2-5), echocardiogram (hypokinesis in anteroseptal wall) and laboratory (CPK 470 U/l) findings and was treated with only blood transfusion. Chest pain disappeared the day after admission, and neither heart failure nor arrhythmia occurred. Based on bone marrow findings (hyperplasia of erythroblast and megakaryocyte), endoscopic (internal hemorrhoids) and laboratory (antiplatelet antibody positive, platelet associated IgG 257.8 ng/10(7) cells) findings, iron deficiency anemia and ITP were diagnosed. Anemia improved after blood transfusion, but thrombocytopenia (< 1.0 x 10(4)/microliter) without active bleeding continued after steroid and gamma-globulin therapy. At discharge, electrocardiogram showed a negative T in I, aVL and V2-5, and T1 and BMIPP myocardial scintigram showed defects in the anteroseptal and apical wall.

[Anorectal diseases in HIV-positive patients. A prospective study].

BACKGROUND: The acquired immunodeficiency syndrome (AIDS) has transformed in a illness pandemic and it is thought that 120 million of people will be infected by the year 2000. About thirty five percent of HIV positive patients will have rectal manifestations during their illness, and from these the most important anorectal manifestation are perianal sepsis, anal condyloma, hemorrhoidal disease, chronic diarrhea syndrome, anal ulcer and anorectal tumors. PURPOSE: To determinate in our medical environment which anorectal manifestation have the most frequency in HIV positive patients. PATIENTS AND METHOD: We developed a linear prospective, comparative and observational trial between December 1993 and December 1994, which included 83 patients distributed in 4 groups: 1) HIV homosexual patients with AIDS, 2) positive HIV homosexual patients without AIDS, 3) negative HIV homosexual patients, 4) negative HIV heterosexual patients. The statistical analysis was done through a chi 2 (Chi square) test. RESULTS: In homosexual HIV patients with the disease, the most common lesion was the anal ulcer (55%). In positive HIV homosexual patients without disease and negative HIV homosexual patients the most frequent lesion is Condyloma acuminata (48 y 84%). In negative HIV heterosexual patients the most frequent disease was anal fistula (40%) and hemorrhoidal disease (36%). CONCLUSION: In negative HIV patients and positive HIV patients without disease the most frequent anorectal lesion is condyloma acuminata; when immunosuppression begins by AIDS, anal ulcer appears and is transformed in the most frequent anorectal disease in AIDS patients.

[Screening for colorectal cancer with an immunological fecal occult blood test].

UNLABELLED: Despite worldwide recommendations, the screening for colorectal cancer (CRC) is not routinely performed in our country. Consequently, we conducted a pilot study to evaluate an immunological fecal occult blood test (FOBT). METHODS: We studied 332 average-risk patients (age over 50 years, asymptomatic, with no personal or family history of CRC) who consulted primary care-generalists from Buenos Aires. They were randomly assigned to screening with one (group I) or three (group II) samples of FOBT (OC-Hemodia). Colonoscopy and/or barium enema and upper gastrointestinal endoscopy were indicated to patients with one or more positive samples. RESULTS: 141 of 162 patients in group I (87.0%) and 142 of 170 patients in group II (83.5%) returned samples (NS). Three of 162 patients were tested positive in group I (1.8%) and 15 of 170 in group II (8.8%) (P = 0.005), with a global positivity of 5.4%. The colon was examined in 14 patients (77.8%) and 4 did not attend after repeated calls. Colonic study showed: CRC 1, adenomatous polyps 3, adenomatous polyps and hemorrhoids 1, diverticula 5, hemorrhoids 1, normal 2, intolerance 1. Upper endoscopy was performed in 9 patients: erosive gastritis 4, duodenal ulcer 1, normal 4. Both studies were normal in only 1 patient. CONCLUSIONS: 1) Immunological FOBT had a good compliance and an adequate positivity rate to be used in the screening for CRC. 2) Despite the use of an immunological test three samples are required to improve results. 3) Upper and lower gastrointestinal lesions, including CRC and polyps, were detected in almost all patients who were examined. 4) Our data justify the use of FOBT in wider population studies to assess its efficacy in the prevention of CRC.

Common anorectal conditions: Part I. Symptoms and complaints.

Anorectal symptoms and complaints are common and may be caused by a wide spectrum of conditions. Although most conditions are benign and may be successfully treated by primary care practitioners, a high index of suspicion for colorectal cancer should be maintained, and all patients should be appropriately investigated. Inspection, palpation and anoscopic examination using an Ive's slotted anoscope provide adequate initial assessment. Pruritus ani usually represents a self-perpetuating itch-scratch cycle and is uncommonly due to infection. The history, as well as the physical examination, can distinguish anal pain due to hemorrhoids, fissure, abscess, cancer or proctalgia fugax. The most frequent causes of rectal bleeding are hemorrhoids, fissures and polyps. Diagnoses associated with difficulty in passing stool can range from constipation to fecal incontinence.

Occult gastrointestinal bleeding in rugby player.

BACKGROUND: Local ischemia and mechanical trauma to hollow abdominal organs are quoted as a cause of gastrointestinal (GI) bleeding during and after long distance running. There are no data on athletes from rugby and other contact sports where mechanical trauma of the abdomen is frequent. METHODS: Occult bleeding in the stool of Croatian national rugby team players has been investigated during and after qualification match with Italy for the World Cup 1999 on June 6th 1998 in Makarska, Croatia. One player with positive test was followed and examined in detail after the game. RESULTS: Among 11 Croatian players authors discovered one with a history of GI symptoms and one with conversion of negative to positive test for occult bleeding in stool after the match. The latter player had no GI symptoms or diseases, took no medications, played only 20 minutes in the match on forward position. Conversion has been found in the second stool sample after game (24 to 48 hours after game). The athlete was followed for 18 months. Persistent low values of hemoglobin, hematocrit and serum iron were revealed, as well as expressed hemorrhoids without signs of haemorrhage or inflammation. CONCLUSIONS: Lower incidence of GI bleeding among rugby players than among long distance runners minimize the importance of mechanical abdominal trauma in the etiology of GI bleeding during sports activity. Hemorrhoids are not quoted as a cause of GI bleeding after sport activity among athletes.

[Results of treatment of anorectal diseases over a 2-year period].

For the success of surgical treatment of anorectal diseases it is necessary to be familiar with different surgical methods for solving the problem. After examination, a surgeon needs to choose optimal method or a combination of two, in order to achieve the best effect. A correct choice of patients suitable for outpatient treatment is of extreme importance because enforcement of such treatment in patients who are suitable for stationary treatment would compromise the method. In this study we have presented the results of outpatient treatment of anorectal diseases during a two-year period (2000-2001). During this period we have studied 597 cases, out of which 524 patients were successfully treated in an outpatient clinic while for 31 patient (5%) we have concluded that they need a stationary treatment to which they were sent and in whom malignant tumors were found. Methods used in the treatment of different stages of hemorrhoides as being the most frequent disease were Barron's elastic ligature, infrared coagulation, sclerotherapy, HAL (Hemorrhoidal Artery Ligation), with two methods combined most commonly. We achieved excellent or very good results of the treatment in 87% of the patients, and only 2 patients had to be sent for surgical treatment. Beside hemoorhoides, methods that can be performed in local anesthesia in an outpatient institutions can be performed as well in cases of other benign conditions (such as lateral sphincterotomy in cases of anal fissure, fistulotomy and similar). Therefore, we have successfully solved 88% of the cases in out-patient clinic. An increased flow of proetologic lesions that were discovered. During 2-year period, we have solved 90% of anorectal diseases by using minimally invasive surgical methods. Successful and simple treatment of benign anorectal diseases increases the flow of patients having such symptoms, which increases the number of discovered malignant tumors.

[Anatomically-induced diagnostic and technical surgical problems and complications in surgery of the anorectum].

Preservation and reconstruction are the key principles for surgical therapy of the anorectal organ of continence. The occlusive strength of the sphincter system varies significantly among individuals. As a rule, women have weaker sphincter muscles than men. Both sexes experience a decrease in sphincter strength with age. The physiological weakness of the anorectal sphincters in females is explained by a relatively smaller amount of sphincter muscle mass and an asymmetric sphincter anatomy which is characteristic for the female pelvic floor. In addition, the spinal centers controlling continence are structurally less complex in women than in men. Chronic constipation and the stress of vaginal deliveries frequently cause damage to the pelvic floor in women by overstretching muscular elements. They appear to play a leading role in the development of spontaneous incontinence, a condition occurring exclusively in women. Preoperative assessment of sphincter strength can be accomplished easily by using a very simple measuring device described earlier. Sphincter pressure measurements are felt to be an essential part of any preoperative work-up in anorectal surgery. The numerous procedures described for reconstructing anorectal sphincter function in patients with incontinence are symbolic operations which at the most create an illusion of continence. Narrowing the levator muscles with plastic bands may improve continence if there is some residual sphincter musculature which is still functional. But it will never cure anorectal incontinence. Recommendable procedures for treatment of anorectal prolaps, anorectal fistulas, and hemorrhoids are discussed. Operative treatment of hemorrhoids which are caused by hyperplastic enlargement of parts of the corpus cavernosum recti is also associated with a greater risk of incontinence in women than in men.

Correlates of constipation in an ambulatory elderly population.

Constipation is a common and often perplexing problem for elderly people. The prevalence of self-reported constipation and factors associated with constipation were investigated in 3,166 people over age 65. Twenty-six percent of women and 15.8% of men reported recurrent constipation (p less than 0.0001). There was a significant increase in reported constipation with increasing age (p less than 0.0001). Multiple factors were found to correlate with self-reported constipation. A logistic regression model revealed 13 factors of significance in predicting constipation. The most important factors were age, sex, total number of drugs taken, pain in the abdomen, and hemorrhoids (p less than 0.0001). Specific drugs do not appear to be important factors in constipation in the elderly. Elderly people who report the use of multiple drugs, pain in the abdomen, and hemorrhoids are at increased risk for constipation.

Organic colonic lesions in patients with irritable bowel syndrome (IBS).

BACKGROUND: To determine whether IBS patients develop organic lesions compared to those without IBS, and to determine type and frequency of these organic colonic lesions. MATERIAL/METHODS: Retrospective review of medical records of 622 IBS patients, ages 19-91 years, over fifteen years that underwent colonoscopy for new gastrointestinal symptoms during the course of their illness. Records of 642 non-IBS patients, who had colonoscopy for gastrointestinal complaints, were reviewed retrospectively as a comparison group. We abstracted and analyzed data related to demographics, history, diagnosis of IBS, and type of colonic lesions reported in the colonoscopy reports. RESULTS: Of the 622 patients diagnosed with IBS, the median duration of the IBS was 11 years (range=1 to 62 years). Colonoscopy findings were normal in 301 patients (48.4%) in the IBS group and 301 patients (46.9%) in the non-IBS group. Among the IBS group, the common organic colonic lesions were hemorrhoids (21.1%) polyps (20.3%) and diverticuli (19%) and angiodysplasia (11.9%). Among the non-IBS group, the common organic colonic lesions were hemorrhoids (22.6%), polyps (22.4%), diverticuli (20.6%) and angiodysplasia (12.1%). There was no difference in the prevalence of organic colonic lesions among patients with or without IBS (p > 0.05). Adjusting for the demographic variables and the number of lesions, there were no differences between the groups (p > 0.05). CONCLUSIONS: IBS patients may also develop organic colonic lesions, thus colonoscopy, if indicated, should not be delayed in these patients because of the assumption that their symptoms are due to IBS alone.

[Health status of urban passenger transportation conductors in Mexico City].

Between 1985 and 1988, a two-phase epidemiological study was conducted at the "Ruta 100" company in Mexico City to examine the harmful effects of the working conditions on drivers of urban transport vehicles. In the first phase, five groups of nine drivers each were interviewed regarding their opinions about their working conditions and possible work-related disorders. On the basis of this information, an epidemiological survey was developed and applied using a polytypic sampling design to some 200 drivers plus two other groups of approximately the same size, one consisting of maintenance workers and the other of office workers, which served as controls. The driver group showed a high prevalence of respiratory and neuropsychiatric disorders, diarrhea, myopia, arterial hypertension, urinary disorders, hemorrhoids, hearing loss, back pain, varicose veins, peptic ulcers, diabetes, cardiopathies, abdominal hernias, and appendicitis. For arterial hypertension, hemorrhoids, nervous disorders, and psychiatric disorders the prevalence ratios of drivers/maintenance workers and drivers/administrative workers were statistically significant.

Efficacy of chlorhexidine gluconate use in the prevention of perirectal infections in patients with acute leukemia.

The frequency of rectal infections is increased in patients with acute leukemia. Complications associated with rectal lesions may be severe enough to cause life-threatening septicemia. Clinical research evaluating the effects of preventive perirectal skin care is scarce. This study's purpose was to determine whether using chlorhexidine gluconate (CHG) in a prophylactic perirectal skin-care regimen decreases perirectal infections and whether it produces more skin irritation than a nonmedicated skin cleanser. The sample consisted of 40 patients, 16 of whom were randomized to use chlorhexidine and 24 of whom were randomized to use nonmedicated skin cleanser. Chi-square and t-tests were used to analyze the incidence of skin breakdown and rectal infections; the correlation between the two factors; a positive history of rectal infections, fissures, or hemorrhoids; presence of hemorrhoids; severity of diarrhea; and duration and severity of granulocytopenia. A positive relationship was found between the severity of granulocytopenia and the incidence of rectal infections (p = 0.02). No significant difference was seen in the occurrence of perirectal infections (p = 0.35) or skin breakdown (p = 0.18) between the two groups. The data suggest that CHG does not offer increased protection against perirectal infections in patients undergoing intensive chemotherapy, nor is it more irritating than a nonmedicated skin cleanser. Further studies are needed to examine the efficacy of hygienic measures such as using skin disinfectants to prevent infections in patients who are immunocompromised.

Diagnostic yield of a positive fecal occult blood test found on digital rectal examination. Does the finger count?

The value of a positive fecal occult blood test (FOBT) found at the time of digital rectal examination is disputed. To determine the significance of a positive FOBT obtained in this manner, the records of 270 patients who underwent colonoscopy for any positive FOBT were retrospectively reviewed. Occult blood was found in 144 patients at the time of digital rectal examination and in 126 individuals after they submitted three spontaneously passed stool specimens. Of the patients with a positive FOBT on rectal examination, 77% were hospitalized at the time compared with only 17% of those with positive FOBTs from spontaneously passed stools. The frequency of colonic abnormalities was similar with both stool collection methods in inpatients and outpatients. No statistically significant differences in neoplastic polyp or colon cancer detection rates, nor in the finding of hemorrhoids or other anorectal abnormalities, were apparent. Therefore, the belief that a positive FOBT found at the time of digital examination can or should be discounted as a false positive (because of the presence of hemorrhoids or other lesions prone to trauma at the time of digital examination) was not substantiated by this study.

Endoscopic sclerotherapy for bleeding rectal varices: a case report.

Rectal varices are not hemorrhoids and they are dilated submucosal veins connecting the middle and inferior hemorrhoidal veins. These rectal varices may occur in patients with portal hypertension because of the formation of portosystemic shunts. Like esophageal varices, the rectal varices may also bleed massively. Herein we report a case of such bleeding which was successfully controlled with endoscopic sclerotherapy to the rectal varices.

Recurrent bleeding from anorectal varices: successful treatment with a transjugular intrahepatic portosystemic shunt.

Anorectal varices are portal-systemic collaterals commonly found in patients with portal hypertension. Although these varices rarely bleed, when bleeding does occur it may be massive and life threatening. Anorectal varices may be mistaken for hemorrhoids and there is no agreed upon method for their definitive diagnosis. Additionally, there is no standard therapy for bleeding anorectal varices, and when techniques designed for the control of hemorrhoidal bleeding are employed the results can be disastrous. We report here the first use of a transjugular intrahepatic portosystemic shunt (TIPS) for the permanent control of bleeding anorectal varices. Magnetic resonance imaging/magnetic resonance venography (MRI/V) was used as a non-invasive method for the identification of anorectal varices and to confirm the successful decompression of these varices with TIPS placement. MRI/V and TIPS may provide significant advances in the diagnosis and treatment of rectal variceal bleeding.

[Anorectal malignant melanoma].

The cases of four patients who are carriers of primitive anorectal malignant melanoma are presented, reviewing at the same time the medical literature available. The clinic of all these patients was similar: pain, proctorrhagia, tumors, tenesmus, hemorrhoids and changes in the intestinal rhythm. One of these cases was similar to thrombosed hemorrhoids, and for this reason we believe that all of the parts that are removed should be biopsied. The prognosis of this pathology is in general adverse, notwithstanding the treatment received. There are very few cases on record that have survived more than 5 years, with early diagnosis and treatment with an abdominal-perineal resection. Radiotherapy and chemotherapy can reduce the size of the lesion but it is acknowledged that the prognosis will not change.
