Bleeding following pregnancy loss before 6 weeks' gestation.

BACKGROUND: Pregnancy loss before 6 weeks' gestation is common, but little has been reported about the associated bleeding. We compared women's bleeding following a pregnancy loss before 6 weeks' gestation with their typical menstruation. METHODS: Women provided daily urine samples while trying to become pregnant and recorded the number of pads and tampons used each day. Thirty-six women had complete bleed data for a loss before 6 weeks' gestation and one or more non-pregnant cycles. RESULTS: Mean bleed length following a pregnancy loss was 0.4 days longer than the woman's average menstrual bleed (P = 0.01), primarily because of more days of light bleeding. Although there was no overall increase in the total number of pads plus tampons used, women with losses bled less than their typical menses following pregnancies of very short duration and more than usual for the pregnancies lasting the longest. CONCLUSIONS: Overall, the bleeding associated with pregnancy loss before 6 weeks' gestation is similar to menstrual bleeding and unlikely to be recognized as pregnancy loss. The intriguing finding that pregnancies of very short duration were associated with less bleeding than the woman's typical menses might reflect endometrial factors associated with loss.

Early gestational bleeding and pregnancy outcome: a multivariable analysis.

The effect of early vaginal bleeding on pregnancy outcome was assessed for 16 305 singleton stillborn and liveborn deliveries at three obstetric units in Jerusalem, Israel during 1975-1976. A total of 2385 women (14.6%) reported gestational bleeding before the seventh month of pregnancy. Of these, 2166 reported light bleeding (spotting), 191 heavy bleeding, and 28 both light and heavy bleeding. Logistic regression models revealed an unexpected interaction among light bleeding, hormone usage, and pregnancy outcome in that the risks of a low birth weight, pre-term and small-for-dates term delivery were significantly increased only for those women who had light bleeding and who had not used therapeutic hormones. Heavy vaginal bleeding, in contrast, was associated with an excess risk of these perinatal complications regardless of hormone usage. There was also a suggestion that certain subgroups of women with vaginal bleeding might be at an increased risk of delivering an offspring with congenital malformations.

Ethnic differences in the duration and amount of menstrual bleeding during the postmenarcheal period.

In 1989, 125 African-American and 123 European-American girls aged 12-14 years living in Durham, North Carolina, were enrolled in a 2-year study in which they maintained a menstrual calendar, recording the date and amount of menstrual bleeding. Weight, exercise, and stress during the previous week were recorded at the start of the menstrual cycle. Ethnicity was the strongest determinant of the duration of menstrual bleeding and of the probability of heavy bleeding. The mean duration of bleeding was 5.1 days for African-American girls and 5.6 days for European-American girls. Low body mass index, high stress, and dieting also influenced bleed duration, but the effects of low body mass index and stress were modified by ethnicity. european-American girls were less likely to have an episode of heavy bleeding (odds ratio = 0.48) than were African-American girls, while high stress increased the risk of having heavy bleeding episode (odds ratio = 1.51). Further investigation of potential ethnic differences in menstrual bleeding characteristics and of the role of stress in provoking heavy bleeding is warranted.

The influence of cyclo-oxygenase specificity of non-steroidal anti-inflammatory drugs on bleeding complications in concomitant coumarine users.

BACKGROUND: Concomitant use of coumarines and non-steroidal anti-inflammatory drugs (NSAIDs) may induce bleeding complications, due to the inhibition of both coagulant factors and platelet function. Unlike non-selective NSAIDs, cyclo-oxygenase-2 (COX-2)-selective NSAIDs interfere very little with platelet aggregation. AIM: To determine whether COX-2-selective NSAIDs are associated with less bleeding complications in coumarine users, compared with non-selective NSAIDs. DESIGN: Prospective, nested case-control study. METHODS: We studied concomitant coumarine and NSAID users over two years. Patients with bleeding (cases), and frequency-matched patients without bleeding (controls), were sent questionnaires regarding possible risk factors for bleeding. International normalized ratio (INR) values were recorded. Univariate and multivariate analyses were used to detect factors contributing to bleeding. RESULTS: There were 1491 reported bleeds. NSAIDs were involved in 14.8%; 3.9% involving COX-2-selective NSAIDs. In non-bleeders, 2601 prescriptions with a coumarine/NSAID combination were detected; 9.7% were COX-2-selective. Adjusted ORs (95% CI) for a bleeding complication were 3.07 (1.18-8.03) for non-selective NSAID use, 3.01 (1.42-6.37) for NSAID use > 1 month, and 1.89 (1.03-3.49) for INR > or = 4.0. DISCUSSION: In coumarine users, COX-2-selective NSAIDs are associated with less bleeding complications than non-selective NSAIDs are. Duration of NSAID use, as well as intensity of coumarine treatment, plays an important additional role. When the coumarine-NSAID combination is inevitable in an individual patient, a COX-2-selective NSAID may be preferred, with careful monitoring of the INR.

Current management of upper gastrointestinal bleeding.

Over a four-year period, 585 patients were hospitalized for massive upper gastrointestinal bleeding. Endoscopy diagnosed the cause of bleeding in 80% of 200 patients so studied. Selective angiography localized the bleeding site in 12 of 20 patients, and infusion of vasopressor stopped hemorrhage in six. Barium studies was 90% accurate in diagnosing ulcer disease but failed to detect gastritis. One hundred thirty (22%) patients were operated upon for medically uncontrolled bleeding. The proportion of patients requiring surgery fell from 33% in year one to 13% in year four. Benign ulcer disease caused bleeding in 51% of surgical patients, while gastritis was found in 20%, esophageal varices in 15% and stress ulcer in 8%. Overall operative mortality was 29%. Among 38 duodenal ulcer patients, mortality was 18%. Vagotomy and pyloroplasty were more effective than resection in this group. Resection for distal gastric ulcers in 22 patients resulted in a mortality of 14% and no rebleeding. While V&P controlled bleeding in 12 alcoholics with gastritis, five (42%) died postoperatively. Mortality among 20 patients with esophageal varices was 35%, although all five survived who had porto-caval shunts. Eight of 10 patients operated upon for stress ulcer bleeding died. Postoperative rebleeding occurred in 14 patients, eight of whom were again operated upon. In all but one a new lesion was found to be responsible for hemorrhage. Increasing use of gastroscopy and selective angiography can be expected to improve diagnostic capabilities in patients with upper gastrointestinal bleeding. Infusing vasopressor into selected arteries should reduce the need for surgical control of gastritis, variceal and stress ulcer bleeding, conditions poorly managed by current operative techniques.

Bleeding colonic diverticula. A reappraisal of natural history and management.

OBJECTIVE: The study was undertaken to correct or reaffirm current recommendations based on old observations of doubtful validity because of their lack of routine colonoscopy, scintigraphy, or angiography. METHOD: Patterns of bleeding were derived from transfusion records of 78 patients admitted 106 times for lower gastrointestinal bleeding with no detectable cause other than colon diverticula. RESULT: Bleeding stopped spontaneously in 82 of 108 episodes and in 66 of 67 patients requiring less than four units of transfusion on any day. When four or more units were required in a day, 25 of 42 patients required emergency surgery. When a bleeding site was identified and removed, only 1 of 25 patients bled again from another diverticulum. After discharge without surgery, 28 of 73 began to bled again. After "blind" colectomy and ileoproctostomy, four of seven patients developed leaks or abscesses, and two died. CONCLUSIONS: Bleeding stopped spontaneously in 75% of episodes and in 99% of patients requiring less than four units of transfusion per day. Bleeding continued in 25% of episodes and in most patients who required four or more units per day. Bleeding sites of those patients who continued to bleed were shown by scintigraphy or angiography. When a bleeding diverticulum is removed, rebleeding is rare. "Blind" resection is unsafe.

Endoscopic control of upper gastrointestinal bleeding.

It has been estimated that gastrointestinal (GI) bleeding occurs in more than 100,000 patients with peptic ulcer disease each year. In 75-80% of the cases, bleeding will be self-limited. A major predictor of persistent or recurrent bleeding is the magnitude of blood loss before the initial evaluation. Endoscopy has an important role in the evaluation of the patient with suspected or presumed upper GI bleeding. Active bleeding at the time of the endoscopy correlates with the more likely probability of persistent bleeding, which carries a higher morbidity and mortality. In addition, there has been continued interest in the finding of a visible vessel. Although there is some controversy as to what a visible vessel actually is and how closely observations will agree about its recognition, there is general agreement that it is an important endoscopic finding and that it carries a high likelihood of rebleeding. In addition to the finding of a visible vessel, many endoscopists feel that ulcers found in the posterior-inferior wall of the duodenal bulb and high on the lesser curve of the stomach should be considered in a separate category. Owing to their proximity to large vessels, some feel that endoscopic management carries a greater risk because of the possibility of inducing bleeding. A wide variety of endoscopic approaches are available for the therapy of upper GI bleeding. It is convenient to divide these therapies into four categories: (a) topical, (b) injection, (c) mechanical, and (d) thermal. Endoscopic therapy for bleeding ulcers has generally been performed with a high degree of safety.(ABSTRACT TRUNCATED AT 250 WORDS)

Octreotide therapy for control of acute gastrointestinal bleeding in children.

OBJECTIVES: To evaluate the outcomes of octreotide use in children with gastrointestinal bleeding with or without portal hypertension. METHODS: The medical charts of children who received continuous octreotide infusion for the indication of gastrointestinal bleeding from January 1995 to December 2000 were retrospectively reviewed. RESULTS: Twenty-one children with portal hypertension received octreotide infusions (1-2 microg/kg/h) during 35 gastrointestinal bleeding episodes. The duration of infusion ranged from 19 hours to 7 days. Bleeding ceased in 71% of children. Post-treatment rebleeding occurred in 52%, and the mortality was 19%. Response to octreotide, rebleeding, and mortality did not differ significantly between patients with or without intrinsic liver disease. Twelve children with gastrointestinal bleeding unrelated to portal hypertension received octreotide during 14 episodes. The duration of octreotide ranged from 3 hours to 36 days. Fifty percent of children had resolution of bleeding during the infusion. Post-treatment rebleeding occurred in 29%, and the mortality was 50%. No major adverse events were observed in either group. CONCLUSIONS: A high rate of bleeding control was achieved with octreotide during acute gastrointestinal bleeding in children with portal hypertension. However, controlled studies are needed for more definitive description of its clinical effects. The role of octreotide is less clear in gastrointestinal bleeding unrelated to portal hypertension.

Endovascular treatment of intractable oronasal bleeding associated with severe craniofacial injury.

BACKGROUND: Severe craniofacial injury may cause intractable oronasal bleeding, which is refractory to conventional treatments. This study will evaluate the efficacy of endovascular treatment for such oronasal bleeding. METHODS: Nine males between the ages of 19 and 62 years who had intractable oronasal bleeding resulting from severe craniofacial injuries received treatments of transarterial embolization using Gelfoam pledgets, polyvinyl alcohol particles, or platinum coils. We then reviewed their clinical and neuroradiologic characteristics retrospectively. RESULTS: In all but one case, angiography demonstrated bleeding points as extravasation. These bleeding points were multiple in seven cases. Except for bleeding from ethmoidal arteries, selective embolization was successful. In all cases, intractable oronasal bleeding was controlled. Patient survival was not directly related to oronasal bleeding, but rather was strongly correlated with associated brain injuries. CONCLUSION: Endovascular treatment is an acceptable treatment for intractable oronasal bleeding associated with severe craniofacial injuries when conventional treatments have failed.

The importance of delayed images in gastrointestinal bleeding scintigraphy.

Although radionuclide methods for the detection of gastrointestinal (GI) bleeding have been available for more than 20 years, the value of delayed images in GI bleeding scintigraphy is still regarded controversially. The aim of this study was to determine the value of delayed images in a group of patients with predominantly low-grade intermittent bleeding. Eighty-nine consecutive GI bleeding scintigraphies of 75 patients were analysed retrospectively. All patients were referred to our department after other diagnostic methods had failed to identify the localization of GI bleeding. After the dynamic study, delayed images were acquired for up to 24 h until a bleeding site was identified. Data on the clinical outcome were available in all but five patients. No patient with a negative scan died from GI bleeding. A positive result was found in 41 patients (55%). The scans of 11 of these 41 patients (27%) became positive during dynamic imaging. Four required immediate surgery and, in another patient, surgery was not performed because of diffuse bleeding of the entire GI tract. One patient died without surgical intervention. Thirty-three scans of 30 of these 41 patients (73%) were positive on delayed imaging only, leading to surgery in 12 individuals. Our findings demonstrate the importance of delayed images in GI bleeding scintigraphy. Many of our patients who required surgery had scans that did not become positive for several hours.

Potentially fatal bleeding in acute pancreatitis: pathophysiology, prevention, and treatment.

INTRODUCTION: Massive bleeding may complicate the course of either acute or chronic pancreatitis. Although the latter is more frequently involved when bleeding occurs in the acute form, a poorer prognosis is to be expected. Abscess, severe inflammation, regional necrosis, and pseudocysts may cause major vessel erosion, with or without pseudoaneurysm formation, whose eventual rupture may result in massive bleeding into the gastrointestinal tract, retroperitoneum, and peritoneal cavity. AIMS: To define the most important pathophysiologic mechanisms and factors that might contribute to a better understanding, better prevention, and more efficient treatment of severe hemorrhage complicating acute necrotizing pancreatitis. Awareness of high-risk conditions occurring during the natural evolution of the disease (from extensive local severe enzymatic damage to late septic sequelae), avoidance of a too early and too aggressive approach to sterile pancreatic necrosis, and providing prompt and effective treatment of local septic complications, when they occur, are crucial steps for bleeding prevention. METHODOLOGY: Forty-four cases of severe bleeding following acute pancreatitis that were reported during the last decade since 1992 (including the six cases reported here) are reviewed, analyzed, and summarized. RESULTS: The overall mortality rate was 34.1%. Splenic artery, portal vein, spleen, and unspecified peripancreatic vessels were the most commonly involved sources of bleeding, with associated mortality rates of 33.3%, 50.0%, 30%, and 28.5%, respectively. Massive hemorrhage was more frequently associated with severe necrosis, with a mortality rate of 37.9%. CONCLUSION: The increased use of diagnostic and interventional radiology, in association with prompt surgical treatment, appears to be the way to improve survival rates in cases of arterial bleeding. Venous bleeding due to lesion of major peripancreatic veins or diffuse bleeding represents a therapeutic challenge, and treatment of these conditions should be tailored to the individual case, as no general rule can be suggested. In extreme cases, open packing or salvage emergency pancreatectomy may represent the only chances for survival.

Postmenopausal uterine bleeding profiles with two forms of continuous combined hormone replacement therapy.

OBJECTIVE: This study was designed to compare the bleeding profiles of conjugated equine estrogens 0.625 mg in combination with 2.5 mg medroxyprogesterone acetate (Prempro; CEE/MPA group), the most widely prescribed continuous combined hormone replacement therapy (CCHRT) in the United States, with 17beta-estradiol 1 mg combined with 0.5 mg norethindrone acetate (Activella; E(2)/NETA group), a newly available CCHRT preparation, over a 6-month period. DESIGN: This study was a prospective, randomized, multicenter, double-blind, controlled trial. A total of 438 healthy postmenopausal women were randomized and received treatment (Activella n = 217, Prempro n = 221). Each woman recorded bleeding diaries daily. Total cholesterol, triglycerides, and endometrial biopsies were obtained at screening and end-of-trial visits. RESULTS: The more favorable bleeding profile was found in the E(2)/NETA (Activella) group. The differences in bleeding patterns were most marked in the first 3 months of treatment in women who were 1-2 years from last menses, with no bleeding in 71.4% vs. 40.0%; ( p = 0.005) and with no bleeding and no spotting in 54.8% vs. 17.1%; (p = 0.001). Triglycerides fell by 8.5% in the E(2)/NETA group and increased by 11.7% in the CEE/MPA group (p < 0.001). Total cholesterol declined by 9.1% and 6.9%, respectively. CONCLUSION: The most important factor in the continuation of HRT is uterine bleeding. E(2)/NETA has significantly less bleeding than the most commonly prescribed CCHRT CEE/MPA, therefore; E(2)/NETA should be associated with improved continuation rates. The patient taking E(2)/NETA will receive effective treatment for her menopausal symptoms with less bleeding.

Abnormal clotting parameters before therapeutic ERCP: do they predict major bleeding?

A total of 399 consecutive patients undergoing 598 ERCPs (endoscopic retrograde cholangiopancreatographies), including 88 pre-cut papillotomies and 206 conventional papillotomies, are described in a retrospective study. Clotting parameters, haemoglobin levels, indications for pre-cut and/or conventional papillotomy and the use of drugs assumed to interfere with blood clotting (anticoagulants, platelet-aggregation inhibitors, low-molecular-weight heparin) were evaluated in order to detect risk factors for ERCP-associated bleeding. The overall incidence of ERCP-associated bleeding was 18/598 (3.0%). The incidence of bleeding in the group without papillotomy was 7/346 (2.0%). This group consisted of patients who underwent only a diagnostic ERCP, patients who had undergone papillotomy previously, patients in whom a renewed attempt was made to extract biliary stones, and patients in whom removal or change of a stent was necessary. The incidence of papillotomy-associated bleeding was 11/252 (4.4%). Pre-cut papillotomy did and conventional papillotomy did not significantly increase the incidence of bleeding: 15.2% (P < 0.001) and 1.9% (P= 1.00) respectively. The incidence of ERCP-associated bleeding in the group not using any drugs interfering with blood clotting was 2.5%. The use of low-molecular-weight heparin (10.3%) during ERCP significantly increased the risk of bleeding (P= 0.01). However, the use of platelet aggregation inhibitors (2.4%) did not (P= 1.00). As the incidence of bleeding in patients with normal clotting parameters, including the patients with abnormal parameters which were well corrected (4.3%), was higher than in patients with abnormal haemostatic screens (2.7%), abnormal coagulation tests did not predict ERCP-associated bleeding.

Risk of upper gastrointestinal bleeding associated with non-aspirin cardiovascular drugs, analgesics and nonsteroidal anti-inflammatory drugs.

OBJECTIVE: To evaluate the risk of upper gastrointestinal bleeding associated with non-aspirin cardiovascular drug therapy, common analgesics and individual nonsteroidal anti-inflammatory drugs (NSAIDs). METHODS: The case group was made up of 1122 consecutive patients admitted with bleeding from a peptic lesion. The 2231 control subjects consisted of 1109 patients hospitalized for other reasons and 1122 outpatients from the same geographical area. The relative risk was calculated by unconditional logistic regression after adjusting for confounding factors. RESULTS: The use of the antiplatelet agent triflusal, and other commonly used cardiovascular drugs, such as beta-receptor blockers and calcium channel blockers, was not associated with increased risk of upper gastrointestinal bleeding. The use of angiotensin-converting enzyme inhibitors reduced the risk of bleeding by 30% (odds ratio 0.7; 95% confidence interval 0.5-0.96). Use of ketorolac (odds ratio 59.4; 95% confidence interval 7.7-454) and piroxicam (odds ratio 19.6; 95% confidence interval 9.3-35.3) carried the highest risk. Use of paracetamol and tramadol was not associated with increased risk of bleeding, but the non-narcotic agent metamizol was associated with a small increase in risk of upper gastrointestinal bleeding (odds ratio 2.6; 95% confidence interval 1.3-5.2). CONCLUSIONS: The use of the antiplatelet agent triflusal and other cardiovascular drugs apart from low-dose aspirin was not associated with gastrointestinal bleeding. The use of either NSAIDs or aspirin increased the risk of gastrointestinal bleeding but, among the analgesics, only metamizol induced a small increase in the risk of gastrointestinal bleeding.

Dose/volume relationship of late rectal bleeding after external beam radiotherapy for localized prostate cancer: absolute or relative rectal volume?

PURPOSE: The purpose of this study was to analyze predictors of late rectal bleeding after external-beam radiotherapy for localized prostate cancer, with a focus on the volume of rectum irradiated. MATERIALS AND METHODS: One hundred twenty-eight patients were treated with external-beam radiotherapy at the Cleveland Clinic Foundation between January 1998 and June 1999. Conformal radiotherapy (CRT) was used to deliver 78 Gy at 2 Gy per fraction in 76 cases, and short-course intensity-modulated radiotherapy (SCIM-RT) was used to deliver 70 Gy at 2.5 Gy per fraction in 52 cases. All contours were determined by one physician. The rectum was outlined from 1 cm above the target structures to 1 cm below the target structures. The entire volume of the rectum, along with the outer rectal wall, was included. All cases had detailed planning parameters that specifically determined the rectal volume receiving the prescription dose (VrPr), that is, 78 Gy for CRT and 70 Gy for SCIM-RT, and the percent of rectal volume receiving the prescription dose (%VrPr). The RTOG scales were used to evaluate late toxicity. The median follow-up was 24 months for all cases (range, 3-34 months), 21 months for SCIM-RT cases (range, 11-26 months), and 28 months for CRT cases (range, 3-34 months). RESULTS: To date, five patients have had grade 1 late rectal toxicity (one CRT case and four SCIM-RT cases), one patient had grade 2 late rectal toxicity (CRT), and three patients had grade 3 late rectal toxicity (all CRT cases). Because of the low number of events, the analysis was performed with all patients experiencing rectal bleeding grouped together. The actuarial rectal bleeding rates at 18 and 24 months were 6% and 8%, respectively. The actuarial rectal bleeding rates at 24 months were identical (8%) for both SCIM-RT and CRT. A multivariate analysis of the following parameters was performed to determine independent predictors of rectal bleeding: age (continuous variable), race (Caucasian vs African American), coverage of seminal vesicles (yes vs no), adjuvant androgen deprivation (yes vs no), technique (CRT vs SCIM-RT), Radiation Therapy Oncology Group acute rectal toxicity score (continuous variable), VrPr (continuous variable in cubic centimeters), and %VrPr (continuous variable). Only the VrPr (cubic centimeter) was an independent predictor of rectal bleeding; %VrPr was not. With different cut-off levels being used, a VrPr of 15 cm3 was significant on univariate analysis; the actuarial rectal bleeding rates at 24 months for patients with a VrPr < or = 15 cm3 versus a VrPr > 15 cm3 were 5% versus 22%, respectively. CONCLUSION> In our study sample, which included both conformal and intensity-modulated radiotherapy patients, the volume of rectum receiving the prescribed radiation dose (the equivalent of 78 Gy) was an independent predictor of late rectal bleeding. The percent of rectal volume receivingthe full dose was not. Using actual volume rather than percent volume also avoids the dependence on the extent of rectal volume contours. We recommend 15 cm3 as the cut-off of the rectal volume not to exceed the prescription dose. The rectal bleeding rate at 2 years for cases with < 15 cm3 receiving the full dose was only 5%.

Bleeding patterns during continuous estradiol with different sequential progestogens therapy.

OBJECTIVE: : To evaluate the effects on monthly bleeding of four different progestogens administered in association with transdermal estradiol in a continuous sequential estrogen-progestin therapy (CS-EPT). DESIGN: : This prospective, open, randomized, clinical trial included 100 healthy postmenopausal women. Patients were randomized into four treatment groups, each consisting of 25 women. Treatment consisted of 50 mug/day transdermal 17beta-estradiol for all women combined to receive four different progestogens (group A: medroxyprogesterone acetate, 10 mg/day; group B: nomegestrol acetate, 5 mg/day; group C: dydrogesterone, 10 mg/day; group D: micronized progesterone, 200 mg/day) per os from the 14th to 25th day of each 28-day cycle. The duration of treatment was 12 cycles. Patients were asked to record in a daily diary the occurrence of any vaginal bleeding, the days of application of each patch, the days of assumption of the different progestogens, and the exact moment of bleeding onset. RESULTS: : A total of 937 cycles could be evaluated. In 690 cycles (73.6%), regular progestogen-related bleeding was reported. Among the other cycles, we observed 73 episodes of amenorrhea (7.8%, each one lasting one cycle), 78 episodes of irregular bleeding (8.3%), and 96 episodes of spotting (10.2%). Patients receiving nomegestrol acetate had a significantly higher incidence of regular progestogen-associated bleeding in comparison with those receiving medroxyprogesterone acetate or natural progesterone, and patients receiving dydrogesterone had a significantly higher incidence of regular progestogen-associated bleeding in comparison with those receiving natural progesterone. CONCLUSION: : Our data suggest that CS-EPT generally leads to regular withdrawal bleeding in women without uterine pathology. Micronized progesterone seems to induce more irregular bleeding episodes.

Posterior epistaxis: identification of common bleeding sites.

OBJECTIVE: The objective of this study was to determine common bleeding sites in the nasal cavity of patients with posterior epistaxis and thus review our management protocol. STUDY DESIGN: A prospective study was carried out from 1989 to November 2003 in the otolaryngology-head and neck surgery department of a tertiary referral center. This study included patients who presented with posterior epistaxis uncontrolled with standard nasal packing and with no identifiable bleeding point on examination under local anesthesia. METHOD: All patients underwent a formal examination under general anesthesia by the senior author of this article. Findings at examination were documented along with subsequent management and its outcome. RESULTS: Forty-three patients were included in this study. Bleeding points were identified in 36 cases. Seven patients had septal bleeding points (20%). The rest were located on the lateral nasal wall (81%). Of these, 4 were on the lateral wall of inferior meatus, 7 on the lateral surface of inferior turbinate, 8 on the lateral wall of middle meatus, and 10 on the lateral surface of middle turbinate. All were located posteriorly. CONCLUSIONS: We recommend examination under general anesthesia when conservative measures fail to control bleeding, concentrating on the posterior aspect of the lateral nasal wall. In addition, the lateral aspect of the middle and inferior turbinates may contain a groove within which bleeding points may be concealed. The lateral position of most bleeding sites indicates that use of nasal packing can only attempt to indirectly tamponade blood flow and is rarely justified bilaterally. Electrothermocautery can achieve excellent results with minimal complications. Failure to identify a bleeding point, after thorough examination under general anesthesia, does not require further intervention unless complicated by further bleeding.

Prevalence and outcome of allergic colitis in healthy infants with rectal bleeding: a prospective cohort study.

OBJECTIVES: Allergic colitis is often diagnosed clinically in healthy infants with rectal bleeding and often treated with costly hypoallergenic formula. The true prevalence of allergic colitis is unknown. We tested the hypothesis that allergic colitis is overdiagnosed in healthy infants with rectal bleeding. The authors also determined whether rectal bleeding in infants without allergic colitis would resolve without diet change. METHODS: For the purposes of this study, allergic colitis was defined histologically as colonic mucosa with >or= 6 eosinophils per high power field and/or eosinophils in colonic crypts or muscularis mucosae. We surveyed all 56 Ohio NASPGHAN members to determine standard practice regarding the evaluation of rectal bleeding in infants. In addition, infants <or= 6 months old with rectal bleeding were recruited from the referral area of Cincinnati Children's Hospital Medical Center. All infants underwent flexible sigmoidoscopy with biopsies at 5, 10 and 15 cm. Formula or maternal diet was changed only for infants with histologic findings of allergic colitis as defined. Study subjects were followed for 9 weeks. RESULTS: In the survey of NASPGHAN members, 84% indicated they would empirically change the diet of an infant with rectal bleeding to treat presumed allergic colitis. In our study population, however, only 14 of 22 (64%; 95% confidence interval, 41-83) infants with rectal bleeding had allergic colitis. Five (23%) had normal biopsies and three (14%) had nonspecific colitis. Rectal bleeding in all infants with normal biopsies or nonspecific colitis resolved without diet change except for 1 infant subsequently diagnosed with infantile inflammatory bowel disease. CONCLUSION: A significant proportion of infants with rectal bleeding may not have allergic colitis and may undergo unnecessary, expensive formula or maternal diet changes that may discourage breast-feeding.
