Site-specific association between supragingival plaque and bleeding upon probing in young adults.

The aim of the present study was to consider supragingival plaque as a risk factor for gingivitis in a group of young adults without destructive periodontal disease. A total of 127 subjects, 17 to 30 years of age, participated. Periodontal probing depth, clinical attachment level as well as bleeding upon probing and supragingival plaque was assessed at 6 sites of every tooth present. The individual odds ratios between plaque and bleeding ranged between 0.237 and 66.6. 23% volunteers had an odds ratio of below 1.2. Only 15% individuals presented with an attributable risk of supragingival plaque for bleeding upon probing of 50% or more. Overall, the odds of bleeding, adjusted for periodontal probing depth, was increased by 67% in the presence of plaque. Large differences were observed at different teeth with the highest odds ratio at mandibular premolars with 2.557 (95% confidence interval 2.033-3.216) and the lowest at maxillary molars with 1.355 (1.161-1.732). It was concluded that there was high interindividual and intraindividual variation of the relative risk for bleeding in the presence of plaque. The observed low overall relative risk has important consequences in educational and health care programmes since the risk of supragingival plaque which is actually attributable for the observed bleeding on probing may be rather small.

Muscle fragment welding for control of massive presacral bleeding during rectal mobilization: a review of eight cases.

INTRODUCTION: Although massive presacral bleeding during rectal mobilization is uncommon, it can rapidly destabilize a patient. Traditional attempts at control include tamponade with pelvic packing and application of sacral thumbtacks. The aim of this review is to describe the anatomic basis of injury and summarize our experience with this challenging problem, with emphasis on the simple, readily available, effective technique of rectus abdominis muscle fragment welding. METHODS: A retrospective review of eight patients who underwent muscle fragment welding for presacral bleeding incurred during rectal mobilization was undertaken. This technique involves harvesting a small piece of rectus abdominis muscle, which is held in place with a forceps to occlude the bleeding site. Electrocautery adjusted to the highest setting is then applied to the forceps to "weld" closed the bleeding point. RESULTS: Control of presacral bleeding was achieved in all eight patients (3 males) with this technique without complications attributable to this method. Previous attempts at pelvic packing failed in all eight patients. CONCLUSION: Muscle fragment welding is a safe, readily available, and highly effective method of controlling massive presacral bleeding.

A retrospective review of enteroclysis in patients with obscure gastrointestinal bleeding and chronic abdominal pain of undetermined etiology.

Our purpose was to determine the diagnostic utility of enteroclysis in the evaluation of obscure gastrointestinal bleeding and abdominal pain of unknown etiology. This is a retrospective review of 97 consecutive patients (mean age, 54.1+/-17.5 [SD] years; 49 male and 48 female) who underwent enteroclysis at Temple University Hospital from January 1994 to October 2001 for the evaluation of obscure GI bleeding or chronic abdominal pain of undetermined etiology. Prior to enteroclysis all patients had an EGD and colonoscopy, which were nondiagnostic for their symptoms. Sixty-three patients (64.9%) had enteroscopy performed prior to enteroclysis that was also negative. Enteroclysis results were defined as positive based on anatomical or functional abnormalities. Analysis of the data included the percentage yield of positive exams, the percentage of positive results per symptom category, and the percentage of patients with a change in clinical management based on positive enteroclysis results. Ninety-seven patients underwent enteroclysis. The indications for enteroclysis were obscure GI bleeding in 67 patients (69.1%) and chronic abdominal pain in 30 patients (30.9%). The number of positive exams was 19 (19.6%). Fourteen of the 67 patients with the indication of GI bleeding had a positive exam (21%), while 5 of the 30 patients with chronic abdominal pain had a positive result (16.7%). There was a change in clinical management due to the enteroclysis results in 10 patients: 7 patients with GI bleeding (10%) and 3 patients with chronic abdominal pain (10%). Positive enteroclysis findings included adhesions (7), filling defects and masses (5), strictures (2), small bowel diverticulosis (1), mucosal abnormalities (3), and a motility disorder (1). The overall positive yield for enteroclysis was 19.6%, with a yield of 16.7% for chronic abdominal pain and 21% for gastrointestinal bleeding. Enteroclysis results changed the clinical management in approximately 10% of the patients.

Minidose aspirin and gastrointestinal bleeding--a retrospective, case-control study in hospitalized patients.

Low or minimal doses of aspirin are widely used for prevention of cardiovascular diseases. Aspirin is known to produce severe adverse gastrointestinal effects, such as bleeding and perforation. Less is known about the risk associated with minidose aspirin. Our aim was to assess the possible association of upper gastrointestinal tract bleeding with minidose aspirin therapy. A retrospective controlled design was used. Patients hospitalized for melena or hematemesis between January 1, 2000, and December 31, 2001, were identified by ICD-9 codes, and their clinical findings were compared to these of patients without upper gastrointestinal bleeding hospitalized during the same period and matched for age and sex. Bleeding was attributed to therapy if patients used a nonsteroidal anti-inflammatory drug or aspirin therapy within 30 days before hospitalization. The study group included 318 patients (59% male), and the control group 141 (65% male). Mean ages were 67 +/- 19 and 64 +/- 19 years, respectively. Study patients had more accompanying diseases, used more medications, and required more blood transfusions than controls (37%, vs. 2% of controls; P < 0.001). Minidose aspirin was used by 28% of the study group and 18% of the controls (P = 0.03). The average dose was 40 +/- 86 and 21 +/- 55 mg/day, respectively (P = 0.012). Only 26% of the study patients received a gastric protective agent. On multivariate analysis, aspirin consumption was the only independent risk factor for upper gastrointestinal tract bleeding. There appears to be an association between minidose aspirin treatment and hospitalization for upper gastrointestinal tract bleeding. Despite the advanced age of the patients, only one-quarter were treated with gastric protective agent.

Variceal Bleeding.

Cirrhotic patients should receive an endoscopy. Those with medium to large varices identified by endoscopy should receive beta-blocker therapy. The initial episode of variceal bleeding should be managed with endoscopic therapy to control the acute bleeding and concurrent infusion of octreotide. Portal hypertension and liver disease should be fully evaluated after such an episode, and patients should be started on first-line treatment (endoscopic therapy and pharmacologic therapy) to reduce the risk of further bleeding. Patients who bleed again after first-line therapy, and those with persistent risk factors whose varices are not obliterated by first-line treatment should be considered for second-line treatment, which is variceal decompression with transjugular intrahepatic portosystemic shunt (TIPS) or surgical shunt. For patients with end-stage liver disease, liver transplantation may be the most appropriate treatment option. The management of variceal bleeding leading up to transplantation depends on the severity of the bleeding and available expertise. Minimal therapy to bridge the patient to transplantation is the goal. Devascularization procedures are reserved for patients who are not candidates for decompression because of venous thrombosis.

Prevention of acute stress bleeding with sucralfate, antacids, or cimetidine. A controlled study with pirenzepine as a basic medication.

In a prospective, controlled, randomized study of a prophylaxis for stress bleeding, 100 high-risk patients in an intensive care unit received, on a daily basis, 1 g of sucralfate every four hours, an antacid every two hours, or 2 g of cimetidine intravenously. All patients also received 50 mg of pirenzepine by intravenous infusion each day. Gastric pH was determined every eight hours. Bleeding was defined as macroscopically visible bleeding. The intragastric pH was less than 4 significantly more often in patients treated with sucralfate than in patients treated with the other agents, but stress bleeding occurred only in patients treated with cimetidine (n = 2) or antacids (n = 2). In the latter two treatment groups, the probability of bleeding correlated with the incidence of pH values below 4. No side effects of sucralfate therapy were observed. The results indicate that prophylactic treatment of stress bleeding with pirenzepine and sucralfate is at least as effective as combined treatment with pirenzepine and cimetidine or antacids.

Identification and preliminary validation of predictors of major bleeding in hospitalized patients starting anticoagulant therapy.

Among 617 hospitalized patients who started long-term anticoagulant therapy, major bleeding developed before discharge in 28 (5 percent) and minor bleeding in another 38 (6 percent), with daily incidence rates of 0.4 and 0.5 percent, respectively. The most common site of bleeding was gastrointestinal, and one patient died from bleeding. Four independent risk factors for major in-hospital bleeding were identified and weighted using multivariate discriminant analysis in a randomly chosen group of 411 patients: co-morbid conditions other than the indication for anticoagulant therapy (specific signs of heart, liver, or kidney dysfunction, cancer, and severe anemia); the use of heparin to begin therapy in patients age 60 years or older; the intensity of therapy (measured by the maximal prothrombin time or partial thromboplastin time); and liver dysfunction that worsened during treatment. These findings were validated in an independent testing group of 206 patients; the risk factors identified 151 patients at low (1 percent) risk of major bleeding, 33 at moderate (6 percent) risk, and 22 at high (23 percent) risk. The accuracy and clinical impact of this prediction rule should be evaluated further in other hospitals.

Gastrointestinal bleeding in the elderly. Morbidity, mortality and cause.

One hundred thirty-six consecutive patients with upper gastrointestinal bleeding were divided by age into three groups, young, middle aged and elderly, and evaluated for the causes and complications of the bleeding episode. Hemorrhagic gastritis was the most frequent source of bleeding in the young, while gastric ulcer was more common in the middle aged and elderly groups. The high mortality in the young (20 percent) was often attributable to associated liver functional abnormalities secondary to alcoholism. The elderly fared better than the young when the source of bleeding was hemorrhagic gastritis, although the results were not statistically significant. On the other hand, the elderly had a significantly higher mortality than the young when the source was gastric ulcer. All three groups did poorly when the source of bleeding was esophageal varices. The mortality rate was essentially the same in the young and elderly patients requiring surgery, suggesting that age alone should not be a deterrent for surgical management of acute gastrointestinal bleeding.

Moderate anticoagulation by salicylate prevents thrombosis without bleeding complications. An experimental study in rats.

It has previously been shown that salicylate (S) acts as a vitamin K (vit K)-antagonist inducing a decrease in plasma levels of vit K-dependent clotting factors and inhibiting the vit K-dependent carboxylation reaction in the liver. In this study we evaluated whether this biochemical effect had a possible functional role. Indeed, we tested in rats the antithrombotic potency of S (175 mg/kg/i.p. twice a day for 3 days) on experimentally induced venous thrombosis. Its possible haemorrhagic effect was evaluated by measuring the bleeding time. Low-dose warfarin (W) (0.2, 0.1, 0.1 mg/kg/i.v. for 3 days) was utilized as control drug. To check for a possible potentiation between S and W, we tested the effects of their combination (S + W). Thrombotest was used to monitor the anticoagulant effect of each treatment. The incidence of thrombus formation, after venous stasis, was not significantly affected by any of the treatments used, but a significant reduction in thrombus weight was observed after either S or W treatment. Both drugs partially prolonged the Thrombotest without affecting either the bleeding time or the peri-operative mortality (mainly due to internal bleeding). When the combination S + W was used, no significant benefit was observed on the prevention of thrombus incidence or weight, although a marked Thrombotest prolongation was recorded. On the other hand this combination resulted in a pronounced bleeding tendency, as expressed in a significant prolongation of bleeding time and increased total mortality. Thus S, at doses inducing moderate anticoagulation may prevent venous thrombosis without relevant bleeding complications.

Clinical assessment of treatments for prolonged bleeding in users of Norplant implants.

The effectiveness of three drugs in controlling prolonged bleeding in the first year of NORPLANT implants use was tested. The drugs were levonorgestrel (L-Ng, 0.03 mg twice a day for 20 days), ethinylestradiol (EE, 0.05 mg per day for 20 days) and ibuprofen (Ib, 800 mg three times a day for 5 days) and were given orally. A control group received a placebo (PL, one pill of lactose for 20 days). Treatment should start each time a woman experienced eight consecutive days of bleeding or spotting. The 183 volunteers were not aware of the drug administered. A daily record of bleeding and spotting and of treatment intake was maintained. One-hundred-forty women completed the study period; 60 never used the prescribed treatment. Women treated with the three test drugs had significantly fewer bleeding and spotting days during the treated month and also throughout the study year than women using the placebo. The mean number of bleeding plus spotting days per actually treated subject in the first year was 77, 94, 101 and 129 days for the EE, Ib, L-Ng and PL groups, respectively. The administration of EE might help in the management of prolonged bleeding during the first year of NORPLANT implants use.

Sugiura procedure in the surgical treatment of bleeding esophageal varices in children: long-term results.

Recurrent bleeding, the high occurrence of encephalopathy, and the impairment of hepatic function in the successful cases of portasystemic shunts have led to increasing dissatisfaction with these procedures in recent years. Between March 1974 and November 1990 we have operated on 15 children for bleeding esophageal varices using the Sugiura procedure (esophageal transection with paraesophagogastric devascularization). In two cases the entire procedure was performed via the thoracic approach. The spleen was left in place in five cases. We have had no mortality. Operative complications included bleeding in the early postoperative period in two children and partial leakage from the esophageal suture in two others. Follow-up was from 4 years 3 months to 16 years 8 months with an average of 10 years 4 months. Long-term results have been gratifying in 12 patients (80%) with disappearance of the varices and no evidence of recurrent bleeding. Three children (20% of the patients) had recurrent bleeding 4 1/2 years, 4 years 2 months, and 2 1/2 years after the surgical procedure. In all cases there was no evidence of esophageal stenosis, gastroesophageal reflux, or hiatal hernia, nor signs of encephalopathy nor impairment of hepatic function. In our opinion the Sugiura procedure is a valid procedure in the surgical treatment of esophageal varices bleeding in the pediatric age with a high rate of success (80%) and without late complications.

Relationship between sonographic endometrial thickness and progestin-induced withdrawal bleeding.

OBJECTIVE: To determine whether the response to the progestin challenge test can be predicted from the endometrial thickness measured sonographically. METHODS: Progestin challenge tests were performed on 44 women with secondary amenorrhea, each of whom also had her endometrial thickness measured by transvaginal ultrasonography and her serum estradiol (E2) levels determined. The relationships between the response to the challenge test, endometrial thickness, and serum E2 levels were studied, as well as whether the presence or absence of withdrawal bleeding could be predicted from the endometrial thickness and serum E2 levels. RESULTS: The endometrium was significantly thicker in 32 women who had withdrawal bleeding (10.3 +/-4.1 mm) than in the 12 who did not bleed (5.0 +/- 1.3 mm) (P < .001). The serum E2 level was also significantly higher in the positive group: 45.3 +/- 19.4 versus 18.6 +/- 8.0 pg/mL (P < .001). Endometrial thickness of 6.0 mm or more predicted the occurrence of withdrawal bleeding with an accuracy of 95.5%. Endometrial thickness was superior to the serum E2 level in predicting withdrawal bleeding. CONCLUSION: Progestin-induced withdrawal bleeding can be predicted from the endometrial thickness measured sonographically.

Somatostatin versus Sengstaken balloon tamponade for primary haemostasia of bleeding esophageal varices. A randomized pilot study.

In this study we evaluate the efficacy of somatostatin (ST) versus balloon tamponade (BT) in controlling bleeding from esophageal varices. Forty-four consecutive patients with active variceal bleeding were randomly assigned to treatment with a continuous infusion of ST at 250 micrograms/h after an initial bolus of 50 micrograms (group A) or to treatment with BT (group B). Five cases were excluded from the final analysis because of methodological issues. Nineteen patients were allocated to group A and twenty to group B. No differences in age, sex, alcohol intake, severity of bleeding or liver failure were found between the groups. Initial haemostasia within the first 4 h of treatment was obtained in 14 (74%) of the patients receiving ST and in 12 (60%) of those receiving BT. Three patients in group A and two in group B had early rebleeding. Bleeding was controlled over a 24-h period or until elective sclerotherapy could be performed in 11 (58%) and 10 (50%) of the patients, in groups A and B, respectively. One BT-treated patient developed aspiration pneumonia. No complications were observed in patients treated with ST. No significant differences in initial haemostasia, definite control of bleeding or complications were found between the two groups. In this study, somatostatin infusion was found to be as effective as Sengstaken BT in controlling acute variceal bleeding until an elective session of endoscopic sclerotherapy could be performed. However, larger studies are still needed to confirm this theory.

Pancreatic pseudocyst as a cause of upper gastrointestinal bleeding.

A 67-year-old man with a history of an attack of pancreatitis was repeatedly investigated for recurrent gastrointestinal bleeding necessitating blood transfusions. Routine investigations did not reveal the source of bleeding. Repeated angiograms also were not diagnostic. A hot spot identified on a 99mTc-pertechnate-labelled erythrocyte scan prompted an endoscopic retrograde cholangio-pancreatography (ERCP), which showed bleeding through the papilla of Vater. The source of bleeding appeared to be a small pancreatic pseudocyst. The patient was treated with a duodenopancreatectomy in which the pylorus was preserved. No rebleeding occurred since the operation. Pancreatic pseudocysts must be considered as a source of upper gastrointestinal bleeding in patients with bleeding of "obscure" origin. 99mTc-pertechnate-labelled erythrocyte scanning and ERCP may be helpful, even when angiography is normal.

A novel statistical approach to analysis of bleeding patterns during continuous hormone replacement therapy.

Previous studies have shown that continuous oral oestrogen-progestogen therapy, which is a relatively new treatment regimen, does not induce endometrial hyperstimulation. However, bleeding disturbances are common during the early months of therapy and in the present study we used both conventional methods of statistical analysis and a stochastic model to describe the bleeding patterns. Four groups of 15 post-menopausal women were given different oral formulations continuously for 1 yr. The oestrogen component in all cases was 2 mg 17 beta-estradiol. The progestogen used was norethisterone acetate at a dose of either 1 mg or 0.5 mg (Groups A and B) or megestrol acetate at a dose of either 5 mg and 2.5 mg (Groups C and D). Each woman kept a daily record of all bleeding episodes, 80% of which occurred during the first 4 mth of therapy. Analysis of variance showed that the high doses of the two progestogens were associated with less spotting and menstrual-like bleeding than the low doses. Stochastic analysis of the bleeding data confirmed that women on the high progestogen doses experienced fewer bleeding episodes than those on the low doses. It also showed that women receiving the high progestogen doses who weighed under 67 kg or had had their last menstruation over 5 yr previously bled less than the other women in the high-dose groups.

Lack of impact of early catheterization and fibrin specificity on bleeding complications after thrombolytic therapy. The TAMI Study Group.

OBJECTIVES: The aim of this study was to assess the hemorrhagic risk associated with fibrin-specific thrombolytic therapy and invasive procedures with acute myocardial infarction. BACKGROUND: Successful coronary artery reperfusion has important prognostic implications. Because immediate coronary angiography is the only method proved to differentiate early fibrinolytic success from failure, its use may be important for selected patients. METHODS: Five hundred seventy-five patients were evaluated with six combined thrombolytic and catheterization strategies. Patients were randomized to intravenous urokinase alone, recombinant tissue-type plasminogen activator (rt-PA) alone, or both; simultaneously they were randomized to an immediate versus a deferred catheterization strategy. Hemorrhagic events were assessed. The correlation of hemorrhage with clinical and hemostatic variables was evaluated. Prespecified transfusion criteria were employed. RESULTS: No difference in baseline characteristics or in hemorrhagic complications was noted among the three thrombolytic regimens. Although mild (< 250 ml) bleeding was more common in the group with immediate catheterization, no clinically significant difference among catheterization groups was seen in moderate to life-threatening hemorrhagic events. Most bleeding occurred at vascular access sites, yet severe and life-threatening hemorrhage occurred in < 1% of patients. Baseline and nadir fibrinogen levels, change in baseline fibrinogen levels and peak fibrin and fibrinogen degradation products did not correlate with bleeding risk. A clinical predisposition for bleeding was observed in women as well as older (> or = 65 years) and lighter (< or = 70 kg) patients. With prespecified transfusion criteria, only a minimal increase in blood product usage was noted with immediate catheterization. CONCLUSIONS: Immediate cardiac catheterization can be accomplished without a clinically significant difference in bleeding risk. Fibrin specificity offers no clear advantage in reducing hemorrhagic risk. Bleeding risk correlates best with baseline patient characteristics. Finally, the amount of blood transfused can be reduced with lower transfusion criteria.

Radiological intervention in upper and lower gastrointestinal bleeding.

The role of angiography in acute upper GI tract bleeding is less a diagnostic than a therapeutic one because it provides a guide to selective embolization of either the left gastric artery, or the gastroduodenal artery and its two principal branches, the pancreaticoduodenal and the right gastroepiploic artery. Angiographic catheter techniques may also provide substantial diagnostic and therapeutic support for the management of acute lower GI bleeding from a variety of bleeding sources. The advantages are minimal invasion and relatively low risk. The intermittent nature of GI bleeding often interferes with the ability of angiography to demonstrate the source of bleeding. However, at times angiographic techniques provide the only reasonable means of localizing and controlling bleeding.

Clinical predictors of bleeding esophageal varices in the ED.

OBJECTIVES: Some authors have found that thrombocytopenia (<118,000/mm3), splenomegaly, and ascites are useful predictors of large esophageal varices in cirrhotic patients. We decide to see whether these factors could also be used to predict bleeding esophageal varices in patients known to have chronic liver disease in the ED. METHODS: A case record review was done of all patients admitted to the ED of Changi General Hospital with upper gastrointestinal bleeding from esophageal varices from October 1999 to April 2004. The criteria of thrombocytopenia, splenomegaly, and ascites were applied retrospectively to these patients to see how accurately they performed in predicting bleeding esophageal varices. RESULTS: Only 55% of patients had thrombocytopenia, whereas 45% had splenomegaly, and 27.5% had ascites. Combining thrombocytopenia with the presence of either ascites or splenomegaly did not improve the yield (only 40%), and only 6 patients had all 3 criteria. Twelve patients with bleeding varices did not have any of the criteria. CONCLUSIONS: Thrombocytopenia, splenomegaly, or ascites is an unreliable predictor of bleeding esophageal varices. Urgent or emergent endoscopy is still advocated to accurately diagnose bleeding esophageal varices.
