Full Text Available Lung cancer has a predilection to widely metastasize to the liver, bone, brain and adrenal glands. Metastasis of primary lung tumors to the stomach is infrequent, with only sporadic cases reported. Most cases are asymptomatic and diagnosed post-mortem on autopsy. The incidence of symptomatic gastrointestinal metastases is extremely rare. Herein, we describe a case of gastric metastasis by squamous cell lung carcinoma, presenting as melena and diagnosed by esophagogastroduodenoscopy. To the best of our knowledge, only twenty other cases in the English literature have reported symptomatic gastric metastasis of lung cancer diagnosed by endoscopic biopsy. A brief review of the literature shows gastric metastasis of lung cancer to have a predilection to occur most frequently in male smokers with the most common type of tumor likely to be squamous cell carcinoma.

Full Text Available BACKGROUND: Acute variceal haemorrhage is a complication of cirrhosis that can be life threatening. It is a pharmacist’s duty to ensure therapeutic and pharmaceutical care which is not only safe and effective for the patient but also is cost-effective in order to attain improvement of the patient’s quality of life. Therefore, pharmacoeconomic evaluation especially cost-effectiveness analysis (CEA, which compares costs and consequences of drug therapy, is needed. This study was aimed to evaluate the therapeutic cost-effectiveness of hematemesis-melena treatment in hepatic cirrhotic patients. METHODS: A total of 42 patients receiving vitamin K and vitamin K-transamin were studied retrospectively from patients’ medical records in 2 years and analyzed with cost-effectiveness grid and average cost-effectiveness ratio (ACER based on Child-Turcotte-Pugh (CTP Score. RESULTS: Cost-effectiveness grid was dominant for vitamin K in patients with CTP Score A. ACER analysis showed a lower score for vitamin K in all patients included CTP Score classification. There was no significant difference in duration of cessation of bleeding treatment in patients with vitamin K compared with vitamin K-transamin in patients with CTP Score A and B, while significant difference was found in patients with CTP Score C. CONCLUSIONS: Vitamin K appeared to be more cost effective as compared with vitamin K-transamin in all patients. The use of vitamin K had greater benefit than the combination with transamin in all patients and CTP Score classification, and thus should be considered as a primary therapy. Therefore, transamin addition as an alternative therapy for hepatic cirrhosis patients with hematemesis-melena should be considered. KEYWORDS: CEA, cost-effectiveness analysis, child-turcotte-pugh score, hepatic cirrhosis, hematemesismelena, vitamin K, transamin.

The clinical features and the countermeasure were examined on 40 disturbances in the lower gastrointestinal tract developed after radiotherapy of cancer of the uterus, the ovary and the penis. Two to nine months after the irradiation with 10,000 R of Telecobalt and about 5,000 mch of 60 Co, complications such as melena, stenosis and fistula formation were developed. Seventeen of the 40 patients complained of melena and were treated as outpatient. Of the rest 23 patients, 11 were radiation proctitis with a large amount of melena, 9 were recto-sigmoid stenosis, 2 were rectovaginal fistula and 1 was fecal fistula formation. These patients received internal therapy composed of transfusion, hemostatic agent, steroid, solcoseryl suppository, antiulcerative drug and vitamin. However, the prognosis of them, particularly of the patients who were exposed a large amount of radiation, was very poor and the death rate reached 9 to 43%. (Kanao, N.)

Gastritis cystica polyposa (GCP) is an uncommon lesion that usually develops at the gastroenterostomy site. A 57 year old man visited a hospital with a complaint of melena. He did not have any surgical history or past medical history. Endoscopy was performed to evaluate the cause of melena, and a polypoid cystic mass in the stomach was found on an endoscopy and endoscopic ultrasonography. The polypoid cystic mass did not show any enhancing solid portion on a computed tomography. The gastric lesion was conclusively confirmed as GCP through endoscopic submucosal dissection. We report a rare case of GCP that occurred in an unoperated stomach.

Rotavirus gastroenteritis causes substantial morbidity and mortality worldwide in children. We report three infants with rotavirus gastroenteritis complicated by various severity of gastrointestinal bleeding. Two patients (cases 1 and 2) recovered completely without any specific treatments. One patient (case 3) died despite extensive treatments including a red blood cell transfusion and endoscopic hemostatic therapy. Rotavirus genotypes G1P and G9P were detected in cases 2 and 3, respectively. Rotavirus antigenemia levels were not high at the onset of melena, suggesting that systemic rotaviral infection does not play an important role in causing melena. © 2015 Wiley Periodicals, Inc.

Numerous reviews indicate bloody hematemesis signifies more severe bleeding than coffee-grounds hematemesis. We assessed severity and outcomes related to bleeding symptoms in a prospective study. Consecutive patients presenting with hematemesis or melena were categorized as bloody emesis (N=1209), coffee-grounds emesis without bloody emesis (N=701), or melena without hematemesis (N=1069). We assessed bleeding severity (pulse, blood pressure) and predictors of outcome (hemoglobin, risk stratification scores) at presentation, and outcomes of bleeding episodes. The primary outcome was a composite of transfusion, intervention, or mortality. Bloody and coffee-grounds emesis were similar in pulse ≥100 beats/min (35 vs. 37%), systolic blood pressure ≤100 mm Hg (12 vs. 12%), and hemoglobin ≤100 g/l (25 vs. 27%). Risk stratification scores were lower with bloody emesis. The composite end point was 34.7 vs. 38.2% for bloody vs. coffee-grounds emesis; mortality was 6.6 vs. 9.3%. Hemostatic intervention was more common (19.4 vs. 14.4%) with bloody emesis (due to a higher frequency of varices necessitating endoscopic therapy), as was rebleeding (7.8 vs. 4.5%). Outcomes were worse with hematemesis plus melena vs. isolated hematemesis for bloody (composite: 62.4 vs. 25.6%; hemostatic intervention: 36.5 vs. 13.8%) and coffee-grounds emesis (composite: 59.1 vs. 27.1%; hemostatic intervention: 26.4 vs. 8.1%). Bloody emesis is not associated with more severe bleeding episodes at presentation or higher mortality than coffee-grounds emesis, but is associated with modestly higher rates of hemostatic intervention and rebleeding. Outcomes with hematemesis are worsened with concurrent melena. The presence of bloody emesis plus melena potentially could be considered in decisions regarding timing of endoscopy.
Full Text Available Six male patients (age group: 30-60 years with aneurysm of the splenic artery presented with massive upper gastrointestinal tract hemorrhage. Five patients presented with hematemesis and one with melena. Chronic pancreatitis was noted in all the patients, four of whom were chronic alcoholics. Endoscopy was not useful in diagnosis. Bleeding through the Ampulla of Vater was seen in the patient with melena. Angiography was diagnostic in all. Pancreatic resection including the aneurysm(2, and bipolar ligation with underrunning of the aneurysm (3 were the operative procedures. Distal pancreatectomy with pancreatogastrostomy was carried out in the patient with hemosuccus pancreaticus. If endoscopy is inconclusive, angiography and early intervention is recommended to reduce the high mortality associated with conservative management.

Mallory-Weiss tears occur rarely during pregnancy, labour and delivery, and the puerperium, despite the increased frequency of retching and vomiting. We describe a Mallory-Weiss syndrome diagnosed during the immediate postpartum period in a 34-year-old primigravida. The syndrome initially manifested as lower gastrointestinal bleeding and melena. If unrecognized, this complication may lead to life-threatening internal bleeding. It is important to look for an occult bleeding source with such a presentation, and prompt intervention is essential.

We report a symptomatic infant with very rare congenital arterioportal and portosystemic venous fistulae in the liver. Multislice CT after partial transcatheter embolisation revealed not only the complicated vascular architecture of the lesion, but also an incidental jejunal arteriovenous malformation which explained the patient's melena. The patient underwent ligation of the hepatic artery and resection of the jejunal arteriovenous malformation. Postoperative multislice CT clearly demonstrated the success of the treatment. (orig.)

Surgical procedures were performed on 25 patients suffering from late-phase intestinal tract disorders induced by irradiation. The primary diseases of these cases were almost exclusively gynecological in nature, such as cancer of the uterine cervix. Symptoms observed in these cases were overwhelming ileus followed by melena, fistulation and free perforation, as well as combination thereof. The most common portion involved was the recto-sigmoidal colon, followed by the ileo-cecum and ileum. As for the relationship of symptoms to the disordered portion, ileus was seen mainly in cases of disorders at the ileocecal portion; melena was observed exclusively in cases of disorders at the rectosigmoidal colon; fistulation was manifested mainly as recto-vaginal fistula or ileo-sigmoidal fistula; free perforation was observed at both the ileum and sigmoidal colon. Colostomy was the most frequent surgical method applied. Only 3 cases were able to undergo enterectomy. Other cases were subjected to enteroanastomosis or enterostomy. In most cases it was nearly in possible to excise the disordered portions. As for the effect of surgical procedures on symptoms, cases of melena or fistulation were all subjected to colostomy; the majority of these cases showed improvement in symptoms. Moreover, a high improvement ratio was obtained in cases of ileus which were subjected to enterectomy and enteroanastomosis. Cases of free perforation showed high improvement ratio irrespective of the surgical procedure given. As for postoperative complications, one case of free perforation at the ileum showed anastomotic leakage after partial resection. For cases suffering from late-phase intestinal tract disorders induced by irradiation, immediate resection of the disordered intestinal tract and anastomosis are ideal. However, conservative operations must be considered, based on the focal condition. (author).
Full Text Available The aim of the meta-analysis was to provide more solid evidence for the reliability of the new classification. A systematic literature search was performed using PubMed, Armed Forces Pest Management Board Literature Retrieval System, and Google Scholar up to August 2012. A pooled odds ratio (OR was calculated using either a random-effect or a fixed-effect model. A total of 16 papers were identified. Among the 11 factors studied, five symptoms demonstrated an increased risk for SDD, including bleeding [OR: 13.617; 95% confidence interval (CI: 3.281, 56.508], vomiting/nausea (OR: 1.692; 95% CI: 1.256, 2.280, abdominal pain (OR: 2.278; 95% CI: 1.631, 3.182, skin rashes (OR: 2.031; 95% CI: 1.269, 3.250, and hepatomegaly (OR: 4.751; 95% CI: 1.769, 12.570. Among the four bleeding-related symptoms including hematemesis, melena, gum bleeding, and epistaxis, only hematemesis (OR: 6.174; 95% CI: 2.66, 14.334; P<0.001 and melena (OR: 10.351; 95% CI: 3.065, 34.956; P<0.001 were significantly associated with SDD. No significant associations with SDD were found for gender, lethargy, retroorbital pain, diarrhea, or tourniquet test, whereas headache appeared protective (OR: 0.555; 95% CI: 0.455, 0.676. The meta-analysis suggests that bleeding (hematemesis/melena, vomiting/nausea, abdominal pain, skin rashes, and hepatomegaly may predict the development of SDD in patients with DF, while headache may predict otherwise.

A teenager was admitted to an outside hospital ED following an episode of melena. He had been complaining of intermittent abdominal pain, nausea, malaise, and easy fatigability for 2 months, with significant worsening of symptoms 2 weeks prior to this episode. He had no significant medical, surgical, or family history. On presentation at the outside ED, he was found to be profoundly icteric and encephalopathic. Initial laboratories suggested anemia, acute kidney injury, and acute liver failure, leading to a presumptive diagnosis of acute fulminant liver failure necessitating transfer to our institution.

We present a patient who initially had melena on anticoagulation and endoscopy revealed a bleeding gastric ulcer. Hemostasis was achieved. The patient had a recurrence of symptoms despite being off anticoagulation months later and at that time repeat endoscopy showed multiple gastric ulcers with surrounding friable mucosa. Biopsy results were significant for light chain associated-amyloidosis. This case represents a rare cause of gastric ulcer.

Full Text Available We report about a previously healthy 72 year-old woman, presented with 6 days of left lower quadrant abdominal pain and constipation. There was no report of fever, melena, hematochezia or change in appetite. The physical exam demonstrated a distended abdomen with palpable left lower quadrant pain, without guarding. CT showed images compatible with a sigmoid diverticulitis and a calcification of the sigmoid colon. After antibiotic threatment, a colonoscopy was performed which revealed the presence of a shell in the sigmoid colon. Our case illustrates the need for a colonoscopy following an attack of diverticulitis to look for a cancer or rarely a foreign body.

In recent years, Obesity (defined as Body Mass Index > 30 kg/m2) has increased its prevalence reaching epidemic levels in countries such as The United States where it has became a national health issue. In Colombia the Obesity prevalence is figured around 14%. Treatment options for Obesity include life style modifications, pharmacologist management and surgical approach (Bariatric Surgery). This article describes a patient with previous bariatric surgery, who presents abdominal pain and melena owed to isquemic process of the alimentary limb caused by an internal hernia which is a potentially lethal condition if it is not highly suspected allowing its early diagnosis and treatment

Intractable bleeding caused by radiation-induced gastritis is rare. We describe a 69-year-old man with intractable hemorrhagic gastritis induced by postoperative radiotherapy for the treatment of esophageal carcinoma. Although anti-secretory therapy with or without octreotide was initiated for hemostasis over three months, melena still occurred off and on, and the patient required blood transfusions to maintain stable hemoglobin. Finally growth hormone was used in the treatment of hemorrhage for two weeks, and hemostasis was successfully achieved. This is the first report that growth hormone has been used to control intractable bleeding caused by radiation-induced gastritis.

A 58-year old man was admitted to the hospital because of melena. He had a 1-year history of mechanical aortic valve replacement and coronary stent placement because of myocardial infarction and he was taking warfarin and clopidogrel. Esophagogastroduodenoscopy and colonoscopy were negative for bleeding. Capsule endoscopy showed bleeding diffuse angiodysplasia of the small bowel. The patient was treated with octreotide 20 mg, at monthly interval. After 25 months there had been no recurrence of gastrointestinal bleeding. The case suggests that mechanical valve replacement may not prevent gastrointestinal bleeding in Heyde syndrome and that octreotide treatment should be considered in these cases.

A 76-year-old woman presented with sudden massive melena, and superior mesenteric arteriography showed an aneurysm in the middle colic artery (MCA). Because she had a history of right hemicolectomy and ligation of the inferior mesenteric artery (IMA) during open abdominal aortic aneurysm repair, embolization of the MCA aneurysm was considered to pose a risk comparable to that of colonic ischemia. A microballoon occlusion test during occlusion of the MCA confirmed retrograde visualization of the IMA branches through the collateral arteries by way of the left internal iliac artery, and embolization was successfully performed using microcoils. No colonic ischemia or aneurysm rupture occurred after embolization.

Full Text Available We report a case of a 70-year-old man, with a status after aortic valve replacement, who presented with melena and hypotension. On physical examination, he was hypotensive, but he responded to resuscitation. Esophagogastroduodenoscopy revealed a submucosal mass in the gastric fundus. Imaging of the chest, abdomen, and pelvis showed no evidence of local or distant metastasis. He underwent a partial diaphragmatic resection, gastrectomy, lymphadenectomy, and Roux-en-Y esophagojejunostomy. Pathology showed a gastric squamous cell carcinoma (SCC invading the diaphragm, with negative margins of resection, and one positive perigastric lymph node. He received chemoradiation, but the patient expired 27 months after surgery.

A 53-year-old-man underwent US-guided percutaneous thermal ablation with a cooled-tip needle of three liver metastases from gastric cancer. Six days later, the patient was re-admitted for melena, scleral jaundice, and anemia. Abdominal US disclosed echogenic material in the gallbladder lumen (hemobilia) and a focal lesion with mixed echotexture in segment III (hepatic hematoma). On day 5 portal cavernomatosis was diagnosed at US and confirmed by color Doppler and a helical CT exam. The case described emphasizes that radio-frequency interstitial hyperthermia may cause not only traumatic injury of the liver parenchyma but also thermally mediated damage of vascular structures.

Objectives The impact of dietary factors on fecal occult blood (FOB) testing has been previously evaluated in cats, but the analytical sensitivity of this point-of-care test remains unexamined. The primary goal of this study was to assess the analytical sensitivity of the FOB test in cats. Methods Five cats were used in a repeated measures study. Following oral administration of blood, feces were collected and tested every 12 h for FOB and melena. All cats were fed an animal protein-free diet starting the week before entry into the study. Blood was administered on a milligram of hemoglobin per kilogram of body weight basis, and dosed at 1.5, 3, 15, 30 and 45 mg/kg hemoglobin in series with a wash-out period between each trial. Results FOB was detected in one cat at 1.5 mg/kg hemoglobin, three cats at 3 mg/kg hemoglobin and in all five cats at 15, 30 and 45 mg/kg hemoglobin. Melena was noted in one cat at 30 mg/kg and four cats at 45 mg/kg, but not at lower doses. Conclusions and relevance Administration of 15 mg/kg hemoglobin (equivalent to about 1.5 ml blood) was sufficient for positive results in all cats. However, detection occurred with as little as 1.5 mg/kg hemoglobin. Thus, FOB has good analytical sensitivity in cats under appropriate clinical situations.

Superwarfarins (brodifacoum, difenacoum, bromodialone and chlorphacinone) are anticoagulant rodenticides that were developed in 1970s to overcome resistance to warfarin in rats. A 26-year-old previously healthy man was admitted to the emergency department with epigastric pain, severe upper and lower gastrointestinal haemorrhage, gingival bleeding and melena. The patient stated that he had been healthy with no prior hospital admissions and no personal or family history of bleeding diathesis. The patient, who later admitted attempted suicide, stated that he had taken 400 g rodenticide including brodifacoum orally for five days prior to admission to hospital. He had oral mucosal bleeding, numerous bruises over the arms, legs and abdomen, and an abdominal tenderness, together with melena. Laboratory tests revealed a haemoglobin level of 12.3 g/dl, leucocyte count of 9.1 × 10(9) /l, haematocrit of 28% and platelet count of 280 × 10(9) /l. The prothrombin time (PT) was > 200 s (normal range 10.5-15.2 s) and the activated partial thromboplastin time (aPTT) was 91 s (normal range 20-45 s). The INR (International normalised ratio) was reported to be > 17 (normal range 0.8-1.2). The thrombin time and plasma fibrinogen levels were in the normal range. The results showed the presence of brodifacoum at a concentration of 61 ng/ml, detected by reversed-phase liquid chromatography.
Full Text Available Background: To report a patient of choledochoduodenal fistulae (CDF who presented with melena and review a specific treatment for CDF. Methods: This study was designed as a retrospective chart review using patient’s clinical data, imaging, endoscopic report, treatment review, and literature review for treatment options. Results: A 74-year-old female presented with diffuse, non-tender abdominal pain and associated melena for one week. Physical examination showed mildly icteric sclera and mild epigastric tenderness on deep palpation. Initial diagnoses included cholangitis with anemia and acute kidney injury. Computed tomography of the abdomen revealed dilated common bile duct (CBD with a likely 1 cm stone at the distal common bile duct. The patient was given intravenous antibiotic and proper fluid administration. An ERCP was performed noting a fistula from the bile duct to the 2nd part of the duodenum with stone impaction. Sphincterotomy was performed from papilla to fistula. Balloon extraction of 1 cm stone from the CBD was done. Conclusion: The clinical presentation of CDF is generally quite nonspecific. In this case report, we present a presentation of a patient with gastrointestinal hemorrhage as an example of the presentation of CDF associated with a CBD stone. This study also discussed recent data concerning proposed treatment of CDF.

To evaluate the effectiveness of pentosanpolysulfate (PPS) in the treatment of gastrointestinal tract sequelae of radiotherapy. Eligible patients were those with grade 1 to 3 radiation related proctitis, diarrhea and/or melena. At least 4 weeks had to elapse since the completion of the radiotherapy course. Patients with bleeding diathesis or ulcers, and patients receiving anticoagulants or chemotherapy were excluded. Stratification criteria included the type of sequelae (proctitis, diarrhea, melena), the severity grade and the onset (3 months post-RT). Patients were randomized to one of the following arms: 100 mg PPS 3 times per day (300 mg/day), 200 mg PPS 3 times per day (600 mg/day), or placebo 3 times per day. If there was no improvement in symptoms after 2 months, the protocol treatment was discontinued. If the symptoms improved or resolved, the protocol treatment was continued for additional 4 months. Patients under treatment were evaluated monthly, than every 2 to 3 months for the next 18 months. A symptom assessment questionnaire was used to measure quality of life endpoints. From June 1999 to March 2001 180 patients were accessioned from 34 institutions. A total of 168 were analyzable. Neither the best observed response within 3 months for the entire population, nor the response rate within sequelae category or the quality of life measures differed significantly between the 3 arms of the study. Administration of PPS has not been associated with an improvement in the clinical course of radiation related morbidity of the gastrointestinal tract.

To evaluate the efficacy and safety of superselective arterial embolization using the microcoil in acute gastrointerstinal hemorrhage. We evaluated 11 of 42 patients who had undergone diagnostic angiography and transcatheter arterial embolization due to acute gastrointestinal hemorrhage and subsequently underwent superselective arterial embolization using the microcoil. Nine were males and two were females, and their age ranged from 33 to 70 (mean, 51) years. The etiologies were bleeding ulcer (n=3D5), pseudoaneurysm from pancreatitis (n=3D3), and postoperative bleeding (n=3D3). The symptoms were melena, hematemesis, and hematochzia, and the critical signs were cecreased hemoglobin and worsening of vital signs. All patients underwent superselective embolization using the microcatheter and microcoil. Bleeding occurred in the gastroduodenal artery (n=3D5), inferior pancreaticoduodenal artery (n=3D2), left gastric artery (n=3D2), right hepatic artery (n=3D1), and ileal branch of the superior mesenteric artery (n=3D1). All cases were treated succesfully, without complications. In one case in which there was bleeding in the right hepatic artery, reembolization with a microcoil was needed because of persistent melena. During follow up, three patients died from complications arising underlying diseases, namely disseminated intravascular coagulopathy, chronic renal failure, and adult resiratory distress syndrome.

Peptic ulcers are an extremely common condition, usually occurring in the stomach and proximal duodenum. However, cases of peptic ulcers accompanied with multiple complications are extremely rare and hard to treat. The present case reinforces the requirement for the early recognition and correct treatment of peptic ulcers accompanied with multiple complications. A 67-year-old man presented with recurrent abdominal pain, fever and melena. The laboratory results showed anemia (hemoglobin 62 g/l) and hypoproteinemia (23 g/l). Abdominal imaging examinations revealed stones in the gallbladder and right liver, with air in the dilated intrahepatic and extrahepatic bile ducts. Endoscopic retrograde cholangiopancreatography failed due to a deformed pylorus. The patient was finally diagnosed with peptic ulcers accompanied with gastrointestinal (GI) bleeding, pylorus obstruction and cholangitis secondary to a choledochoduodenal fistula during an emergency pancreatoduodenectomy, which was performed due to a massive hemorrhage of the GI tract. The patient recovered well after the surgery.
Full Text Available Gastroaortic fistula formation is a very rare complication following oesophageal resection and, in most cases, leads to sudden death. We report the case of a 65-year-old male with an adenocarcinoma of the oesophagus who underwent neoadjuvant chemoradiation followed by a minimally invasive transthoracic oesophagectomy with gastric tube reconstruction and intrathoracic anastomosis. After an uneventful postoperative course and hospital discharge, the patient reported blood regurgitation on postoperative day 23. Endoscopy revealed an adherent blood clot on the oesophageal wall, which after dislocation caused exsanguination. Autopsy determined the cause of death being massive haemorrhage due to a gastroaortic fistula. The sudden onset of haemorrhage makes this condition particularly difficult to treat. Recognition of warning signs such as thoracic or epigastric pain, regurgitation of blood, or the passing of bloody stools or melena is crucial in the early detection of fistula and may improve patient outcome.

Full Text Available Acute esophageal necrosis (AEN, also called “black esophagus,” is a condition characterized by circumferential necrosis of the esophagus with universal distal involvement and variable proximal extension with clear demarcation at the gastroesophageal junction. It is an unusual cause of upper gastrointestinal bleeding and is recognized with distinct and striking mucosal findings on endoscopy. The patients are usually older and are critically ill with shared comorbidities, which include atherosclerotic cardiovascular disease, diabetes mellitus, hypertension, chronic renal insufficiency, and malnutrition. Alcoholism and substance abuse could be seen in younger patients. Patients usually have systemic hypotension along with upper abdominal pain in the background of clinical presentation of hematemesis and melena. The endoscopic findings confirm the diagnosis and biopsy is not always necessary unless clinically indicated in atypical presentations. Herein we present two cases with distinct clinical presentation and discuss the endoscopic findings along with a review of the published literature on the management of AEN.
Full Text Available Hookworm infection is a common intestinal nematodes in the world. Patients with a light hookworm infection are usually asymptomatic, but a moderate or heavy hookworm burden can result in fatigue, recurrent abdominal pain, and iron-deficiency anemia. We presented a case of 61-year-old man complained of general malaise and melena for 6 months due to hookworm infection. There is no eosinophilia, and the stool exam only revealed positive of occult blood, without ova or parasite identified. Upper endoscopy revealed several squirming red worms in duodenum. Hookworm (Ancylostoma duodenale infection is diagnosed and eradiated by mebendazole successfully. His anemia is corrected after treatment. Hence, hookworm infection should be noted in eldler patients with long term anemia in Taiwan. It is also important to check carefully in the duodenum at routine upper gastrointestinal endoscopy.

A 2-month-old boy was referred for assessment of severe upper gastrointestinal tract bleeding and melena. On physical examination, a continuous murmur was heard over the right upper quadrant of the abdomen. A splenomegaly and dilated veins were also noted on the abdominal wall. Liver functions were normal. There was no history of trauma or jaundice. Doppler ultrasonography, magnetic resonance arteriography and angiography suggested the presence of an intrahepatic arteriovenous fistula between the phrenic artery and the portal vein. Management consisted of successful embolization by coiling of the phrenic artery. To our knowledge this is the first documented case report of a congenital fistula between the phrenic artery and the portal vein.

Common complications of Henoch-Schönlein purpura (HSP) that lead to surgical intervention include intussusception, perforation, necrosis, and massive gastrointestinal bleeding. Acute appendicitis is rarely seen as a complication of HSP. A seven-year-old boy was admitted for arthralgia, abdominal pain, hematochezia, melena, and purpuric rash on the lower extremities. On admission day abdominal ultrasonography was normal, but on day 5, he became pyrexial and developed right iliac fossa pain and tenderness with guarding. Ultrasonography showed distended appendix surrounded by hyperechoic inflamed fat. On exploration an acutely inflamed, necrotic appendix was removed and grossly there was an appendiceal perforation in the appendiceal tip. Microscopically some of the small blood vessels in the submucosa showed fibrinoid necrosis with neutrophilic infiltrations. The authors report the case of a child who developed acute perforative appendicitis requiring appendectomy while on treatment for HSP. PMID:16224172

Radiation-induced gastritis is an infrequent cause of gastrointestinal bleeding. It is a serious complication arising from radiation therapy, and the standard treatment method has not been established. The initial injury is characteristically acute inflammation of gastric mucosa. We presented a 46-year-old male patient with hemorrhagic gastritis induced by external radiotherapy for metastatic retroperitoneal lymph node of hepatocellular carcinoma. The endoscopic examination showed diffuse edematous hyperemicmucosa with telangiectasias in the whole muscosa of the stomach and duodenal bulb. Multiple hemorrhagic patches with active oozing were found over the antrum. Anti-secretary therapy was initiated for hemostasis, but melena still occurred off and on. Finally, he was successfully treated by prednisolone therapy. We therefore strongly argue in favor of perdnisolone therapy to effectively treat patients with radiation-induced hemorrhagic gastritis.

The authors describe the discovery of ascending colonic variceal veins via celiomesenteric diagnostic angiography following a bout of melena in a 44-year-old woman. Magnetic resonance imaging, including phase-contrast MR venography, allowed visualization of the portal and systemic veins immediately after the initial angiograms. The hemorrhagic episode did not resolve until after transjugular intrahepatic shunt insertion and selective variceal embolization through the shunt. At 1 week-, 3 months-, and 6 months post treatment, follow-up MR venography no longer revealed the presence of colonic varices. Colonoscopy at 6 months was normal and the patient did not have any further episodes of bleeding until a liver transplantation was performed after 9 months. (orig.)

Enfermedad Actual: Se inició hace unos dos años por la aparición de constipación pertinaz, pirosis, acedías, dolor epigástrico y sensación de hambre dolorosa que calmaba con las comidas; ocasionalmente ha presentado melenas. Hace seis días, sintió intenso dolor epigástrico de tipo punzante, irradiado hacia el ángulo inferior del omoplato izquierdo, seguido poco después de gran distención abdominal con retención de heces y gases, vómito y hematemesis inicial. Estos fenómenos fueron tratados fuera del hospital con purgantes y enemas sin ningún resultado, pues no retuvo los enemas y vomitó los purgantes. El cuadro se agudizó adquiriendo los caracteres de un abdomen agudo, por lo cual ingresa al hospital.

A 69-year-old man visited our hospital because of melena and anemia. Colonoscopy revealed a type 3 tumor at sigmoid colon, and by abdominal CT, we detected a sigmoid colon cancer invading the urinary bladder with a single liver metastasis. The patient required sigmoidectomy with partial hepatectomy and total urinary bladder resection. Preoperative chemotherapy with mFOLFOX6 was initiated as a part of multidisciplinary therapy. After the 6th course was completed, CT revealed a reduction in the primary tumor's size and the disappearance of liver metastasis. After the 8th course was completed, we performed urinary bladder conserving sigmoidectomy. The pathological diagnosis of the surgical specimen was tub1, pSS, ly0, v0, pN0, and pStage II. Down-sizing chemotherapy might improve the quality of life(QOL)of colon cancer patients with extensive invasion of the urinary bladder.

Bleeding is a common problem in cancer patients, related to local tumor invasion, tumor angiogenesis, systemic effects of the cancer, or anti-cancer treatments. Existing bleeds can also be exacerbated by medications such as bevacizumab, nonsteroidal anti-inflammatory drugs (NSAIDs), and anticoagulants. Patients may develop acute catastrophic bleeding, episodic major bleeding, or low-volume oozing. Bleeding may present as bruising, petechiae, epistaxis, hemoptysis, hematemesis, hematochezia, melena, hematuria, or vaginal bleeding. Therapeutic intervention for bleeding should start by establishing goals of care, and treatment choice should be guided by life expectancy and quality of life. Careful thought should be given to discontinuation of medications and reversal of anticoagulation. Interventions to stop or slow bleeding may include systemic agents or transfusion of blood products. Noninvasive local treatment options include applied pressure, dressings, packing, and radiation therapy. Invasive local treatments include percutaneous embolization, endoscopic procedures, and surgical treatment.

Angiodysplasia of the colon is one of the most common causes of major lower intestinal tract bleeding in the elderly; it occurs predominantly in the cecum and on the right side of the colon and is thought to result from degenerative changes associated with aging. The clinical presentation is varied, ranging from hematochezia or melena to iron-deficiency anemia resulting from long-term blood loss. Accurate diagnosis may require a combination of diagnostic techniques, such as angiography, nuclear scanning, and colonoscopy. The management plan should be individualized for each patient depending on severity, rate of rebleeding, and issues of comorbidity. Although conservative medical management is a reasonable option for many patients, endoscopic treatment has generally replaced surgery as the first line of definitive treatment for angiodysplasias in most of these patients. The risk of rebleeding is a considerable problem, and surgical therapy yields better results in this aspect. The role of hormonal therapy is not clearly established.

We present a case of a 56-year-old man with 3 synchronous gastric tumors. The patient presented with melena, and 3 gastric abnormalities were detected on gastroduodenoscopic examination, including a small ulcerative lesion in the gastric antrum, a submucosal mass in the gastric body, and severe erosion in the fundus. Histological examination of biopsy samples yielded respective diagnoses of gastric adenocarcinoma, gastritis, and mucosa-associated lymphoid tissue (MALT) lymphoma. The patient first received medication to eradicate any underlying Helicobacter pylori infection, which might have been a cause of the MALT lymphoma. Four weeks later, after examination of repeat biopsy samples revealed that the MALT lymphoma had resolved, the patient underwent subtotal gastrectomy. Further histological examination of resected tissue confirmed the antrum lesion as adenocarcinoma and the body lesion as schwannoma. To our knowledge, this is the first reported case of synchronous triple primary gastric adenocarcinoma, MALT lymphoma, and schwannoma.

Peptic ulcer bleeding is treated using endoscopic hemostasis using clips or bands. Pancreas divisum (PD), a congenital anomaly of the pancreas, usually has no clinical symptoms; however, pancreatitis may occur if there are disturbances in the drainage of pancreatic secretions. We report an unusual case of PD accompanied by acute pancreatitis, following endoscopic band ligation for duodenal ulcer bleeding. A 48-year-old woman was admitted to our hospital due to melena. An upper endoscopy revealed a small ulcer with oozing adjacent minor papilla. An endoscopic band ligation was performed on this lesion. Acute pancreatitis developed suddenly 6 hours after the band ligation and improved dramatically after removal of the band. Magnetic resonance cholangiopancreatography was performed, revealing complete PD. Endoscopic band ligation is known as the effective method for peptic ulcer bleeding; however, it should be used carefully in duodenal ulcer bleeding near the minor duodenal papilla due to the possibility of PD.

Pancreatitis can be associated with significant complications. Bowel hematoma is a rare complication and the second part of the duodenum is the most commonly affected site. Hematomas affecting other parts of the bowel are extremely rare. A 53-year-old female with a history of atrial fibrillation and ischemic heart disease on anticoagulants and aspirin presented with abdominal pain of a few days duration which had worsened prior to presentation. This was associated with abdominal distension, vomiting and melena. Laboratory investigations showed elevated serum amylase, coagulopathy and severe anemia. Computed tomography imaging showed a jejunal hematoma and pancreatitis with peripancreatic inflammation. She responded to conservative treatment in addition to correction of the coagulopathy and a blood transfusion. Her symptoms were resolved within a few days and a repeat computed tomography scan two months later showed complete resolution of the hematoma and the pancreatitis. Our case demonstrates a rare complication of acute pancreatitis in a patient with risk factors.

In South Korea, nationwide surveillance for severe fever with thrombocytopenia syndrome (SFTS) began during 2013. Among 301 surveillance cases, 35 hospitalized case-patients in 25 areas were confirmed by using virologic testing, and 16 (46%) case-patients subsequently died. The SFTS cases occurred during May-November and peaked during June (9 cases, 26%). The incidence of SFTS was higher in the southern regions of South Korea. Age and neurologic symptoms, including decreased level of consciousness and slurred speech, were heavily associated with death; neurologic symptoms during the first week after disease onset were also associated with death. Although melena was common among patients who died, no other hemorrhagic manifestations were substantively more common among those who died. No effective treatments, including ribavirin, were identified. Expansion of SFTS surveillance to include the outpatient sector and development of an antibody test would enhance completeness of SFTS detection in South Korea.

A woman, aged 84 years, presented to our emergency department with posteriorly radiating chest pain that began following dinner. She reported no change in bowel habits, hematochezia, or melena. She had previous peptic ulcer disease and a long-standing history of gastroesophageal reflux disease. Her medications included acetylsalicylic acid and rabeprazole. Electrocardiogram and troponin analyses were negative for ischemic heart disease. The emergency physician suspected an aortic dissection, and computed tomography (CT) chest and abdomen scans were performed with and without IV and oral contrast. The aorta was normal and the noncontrast images demonstrated a hyperdense mass (not shown) that did not enhance consistent with a large intramural hematoma extending from the upper esophagus (level of T2 vertebral body) to the fundus of the stomach (Figures 1A and B).

Diagnostic imaging and embolization therapy for the uncommon portal and mesenteric vein-inferior vena cave shunt (PV·SMV-IVC shunt) are reported. As the frequency of clinical symptoms such as hematemesis, melena and confusion caused by gastrointestinal varices, or hepatoencephalopathy was about 40%, it was important for this disease entity to be diagnosed with noninvasive diagnostic images. The careful examination of the area around the right renal vein was able to overcome the low diagnostic rate of 20-40% obtained with US and CT images. In cases of simple PV·SMV-IVC shut without gastrointestinal varices, embolization therapy using steel coils and done by the intravenous approach is easy and noninvasive. On the other hand, in cases of complex PV-SMV-IVC shunt with gastrointestinal varices, dual balloon occluded embolization therapy using a liquid sclerosing agent and done by the intravenous and portal approaches is preferable.

Full Text Available We report a case of bevacizumab- (BEV- induced thrombocytopenia in a 59-year-old man with adenocarcinoma of colon. After colectomy, the patient was treated with twelve cycles of FOLFOX-4 (folinic acid, 5-fluorouracil, and oxaliplatin regimen. On relapse, he was treated with FOLFIRI (folinic acid, 5-fluorouracil, and irinotecan regimen along with BEV 10 mg/kg for 6 cycles. After that, BEV was continued for maintenance as a single agent at an interval of three weeks. After the13th cycle of BEV, the patient developed melena with epistaxis and thrombocytopenia, from which he recovered on withdrawal of BEV. On rechallenge with half the initial dose, there was once again a reversible drop in platelet count. The proposed mechanism of thrombocytopenia may be immune-mediated peripheral destruction of platelets.

A 50-year-old male immigrant from Ethiopia presented for consultation after 3 years of hematochezia/melena requiring > 25 units of blood transfusions. Physical examination revealed severe proximal muscle wasting and weakness, central obesity, proptosis, and abdominal striae, accompanied by eosinophilia, elevated hemoglobin A1c, elevated 24-hour urinary cortisol, lack of suppression of 8 am cortisol levels by 1 mg dexamethasone, and inappropriately elevated random adrenocorticotropic hormone (ACTH) level. Histopathological examination of gastrointestinal biopsies showed large numbers of Strongyloides stercoralis, indicating Strongyloides hyperinfection. Treatment with 2 days of ivermectin led to resolution of gastrointestinal bleeding. This syndrome was due to chronic immunosuppression from a pituitary ACTH (corticotroph) microadenoma, of which resection led to gradual normalization of urine cortisol, improved glycemic control, resolution of eosinophilia, and no recurrence of infection.

Abdominal aortic aneurysms (AAAs) are mostly asymptomatic. If aortic aneurysms become symptomatic, complications include peripheral embolization, acute aortic occlusion, and aortic rupture. However, there are also unusual complications caused by aortic aneurysms. An 87-old male with dabigatran therapy presented with newly developed melena and acute renal failure. Radiological imaging revealed an AAA with thrombotic and calcified deposits which affected the renal arteries. Gastrointestinal bleeding and hypercoagulation caused by renal failure which was triggered in turn due to an AAA. Adapted antihypertensive therapy and initiation of simvastatin 40mg once daily as well as antiplatelet therapy with aspirin 50 mg once daily due to patient's refusal of any aneurysm intervention. Neither bleeding event nor aneurysm rupture occurred with the adapted antihypertensive therapy, simvastatin and aspirin. Nonruptured AAAs can cause rare, unusual, and even life-threatening complications depending on their size and anatomical position.

Abstract Rationale: Abdominal aortic aneurysms (AAAs) are mostly asymptomatic. If aortic aneurysms become symptomatic, complications include peripheral embolization, acute aortic occlusion, and aortic rupture. However, there are also unusual complications caused by aortic aneurysms. Patient concerns: An 87-old male with dabigatran therapy presented with newly developed melena and acute renal failure. Radiological imaging revealed an AAA with thrombotic and calcified deposits which affected the renal arteries. Diagnoses: Gastrointestinal bleeding and hypercoagulation caused by renal failure which was triggered in turn due to an AAA. Interventions: Adapted antihypertensive therapy and initiation of simvastatin 40mg once daily as well as antiplatelet therapy with aspirin 50 mg once daily due to patient's refusal of any aneurysm intervention. Outcome: Neither bleeding event nor aneurysm rupture occurred with the adapted antihypertensive therapy, simvastatin and aspirin. Lessons: Nonruptured AAAs can cause rare, unusual, and even life-threatening complications depending on their size and anatomical position. PMID:28445318
Full Text Available Heterotopic pancreatic tissue of the stomach is a rare condition. Gastric diverticulum is also a rare condition, mostly located at the fornix. Therefore, the existence of a pyloric gastric diverticulum containing a submucosal tumor proved to be heterotopic pancreatic tissue of the stomach is an extremely rare condition. The patient was a young thin male with epigastralgia chronically treated for gastritis/ulcer. Following an episode of melena, he underwent gastroscopy that diagnosed antral gastric diverticulum containing a polyp. The lesion was surgically removed. The pathology report stated: heterotopic pancreatic tissue of the stomach with secondary development of a traction diverticulum. Heterotopic pancreas tissue of the stomach is a rare condition but the association with gastric diverticulum is completely unusual. The possibility of the ectopic tissue leading to secondary diverticulum development should be considered.

We report a rare case of diffuse tracheo-bronchitis as a complication of Crohn's disease. A young man with a long-standing history of Crohn's enterocolitis initially presented with epigastric pain and melena. Upper endoscopy revealed erythematous, edematous, and friable mucosa with erosions, particularly in the pyloric channel, causing gastric outlet obstruction, and a nonbleeding ulcer in the corpus of stomach. Biopsy of these lesions showed chronic gastritis and a noncaseating epithelioid granuloma, consistent with active Crohn's disease. The patient was treated with a course of corticosteroids and the gastric symptoms resolved. A few months later, he developed fever, cough, hemoptysis, and rash. Bronchoscopy demonstrated a markedly thickened and very inflamed trachea with extensive friable, whitish lesions and ulcerations. Histology showed severe noncaseating granulomatous inflammation. The patient improved with a 6-week oral, followed by an additional 4-week inhaled, corticosteroid treatment. Since then, he has been doing well without relapse of pulmonary symptoms for 2 years.

Symptoms of epigastric pain raise the possibility of peptic ulcer disease and lead to an examination of the stomach and duodenum. Hematemesis or melena is also a strong indication. The nausea-vomiting complex on a subacute or chronic basis raises the possibility of an obstructive lesion. A palpable mass in the upper abdomen may involve the stomach. Weight loss and anorexia are less specific symptoms but can occur with gastric cancer. Major changes in indications have occurred now that ultrasonography, computed tomography (CT), and magnetic resonance (MR) imaging are available. No longer is the gut studied to detect extra-gut disease. Currently, the duodenal contour is not important in the search for pancreatic disease. All intra-abdominal structures can now be seen directly using CT or ultrasound
Full Text Available Objective: In this study, it was aimed to evaluate demographic and laboratory characteristics of the patients with upper gastrointestinal system (GIS bleeding define the factors leading to bleeding. Methods: The study included 285 patients aged between 18 and 89 years who were followed and treated for upper GIS bleeding in our Internal Medicine Clinics. Patients’ demographic and aboratory data, endoscopic findings, treatment methods, ospitalization length and need for blood transfusions were determined. Results: The mean age was 62.7±18.3 years with the male/female ratio of 2.2/1. The most common finding was melena (45.3%, and the second melena with hematemesis (33%. 76.84% of the patients had the history of drug use, mostly non-steroid anti-inflammatory drugs (NSAIDs (45.26% and aspirin (23.86%. The mean hospitalization length was 8.3±4.9 days. Blood transfusion was required in 74.04% with the mean 3,14±1,41 units. Bleeding recurrence was seen in 10.25%. Duodenal ulcer was observed as the most common cause of GIS bleeding (29.82% and gastric ulcer was the second (21.75%. The treatment methods were medical in 73.34%, endoscopic sclerotherapy in 22.46%, hemoclips in 1.40% and band ligation in 0.70% of the patients. Upper GIS bleedings were mostly occurred in August (11.9% and least occurred in December (3.5%. Conclusion: The majority of the patients have history of drug use, like NSAIDs and aspirin leading to bleeding. We suggest that the usage of these drugs should be controlled and used only with accurate indications especially in elderly patients.
Full Text Available The incidence of abomasal mucosal diseases in dairy cows suffering from gastrointestinal disorders is becoming more frequent in modern intensive production. Clinical signs are often non-specific. In this study, 67 dairy cows with gastrointestinal disorders and 9 healthy dairy cows as the control group were used. In order to make a tentative diagnosis, a complete physical examination was performed, and the fecal samples were taken from each cow for the fecal occult blood (FOB and the fecal egg count (FEC. Blood samples were taken from the coccygeal vein for WBC, Hematocrit (PCV evaluations, and serum biochemical analysis. Serum pepsinogen activity and total protein; albumin and globulin were measured using validated standard methods. The statistical analysis was performed using SPSS software. The level of significance was set at P<0.05. A significant increase in serum pepsinogen activity was seen in all the cases of abomasal displacements compared to the control group. Among the abomasal displacement groups a significant increase in serum pepsinogen activity was seen in abomasal displacements with suspected abomasal ulcer in comparison with those without any signs of abomasal ulcer (positive FOB and melena. No considerable differences were observed between WBC, PCV, and total protein and globulin in different gastrointestinal disorders and the control group. In this study, the serum pepsinogen activity in all dairy cows with signs of abomasal ulcer (melena and positive fecal occult blood test was higher than the control group, since all of the cases had negative abomasal parasites; these increases in the signs of abomasal ulcer could predict abomasal ulcer complication in the cases of displacements.

We present the case of an 80 years old man, with upper gastrointestinal bleeding who developed a black esophagus after hypotensive episodes. Necrosis was confirmed histologically. Hematemesis and melena are present in more than 70% of the cases. Endoscopic findings show black discoloration of the distal esophagus with proximal extension ending sharply at the gastroesophageal junction. Diagnosis is reached endoscopically with histological support. Mortality is high (up to 50% even though related to the patient's underlying condition. Finally, we may say that to keep in mind the posibility of AEN is a key factor in its diagnosis, particularly in older patients with associated morbidity and evidence of upper gastrointestinal bleeding.

Full Text Available Portal hypertension commonly arises in the setting of advanced liver cirrhosis and is the consequence of increased resistance within the portal vasculature. Less commonly, left-sided noncirrhotic portal hypertension can develop in a patient secondary to isolated obstruction of the splenic vein. We present a rare case of left-sided portal hypertension and isolated gastric varices in a patient with large B-cell lymphoma, who was treated with splenic artery embolization. The patient is a 73-year-old male with no previous history of liver disease, who presented with coffee ground emesis and melena. On admission to hospital, he was found to have a hemoglobin level of 3.4 g/l. Emergent esophagogastroduodenoscopy showed isolated bleeding gastric varices (IGV1 by Sarin classification in the fundus and cardia with subsequent argon plasma coagulation injection. He was transferred to our tertiary center where work-up revealed normal liver function tests, and abdominal ultrasound showed patent hepatic/portal vasculature without cirrhosis. MRI demonstrated a large heterogeneously enhancing mass in the pancreatic tail, with invasion into the spleen and associated splenic vein thrombosis. Surgery consultation was obtained, but urgent splenectomy was not recommended. The patient instead underwent splenic artery embolization to prevent future bleeding from his known gastric varices. Pathology from a CT-guided biopsy was consistent with diffuse large B-cell lymphoma. PET imaging showed uptake in the splenic hilum/pancreatic tail region with no additional metastatic involvement. He was evaluated by the Hematology Department to initiate R-CHOP chemotherapy. During his outpatient follow-up, he reported no further episodes of melena or hematemesis. To the best of our knowledge, there have only been two published case reports of large B-cell lymphoma causing upper gastrointestinal bleeding from isolated gastric varices. These cases were treated with splenectomy or

Full Text Available BACKGROUND: Angiodysplasia is a distinct mucosal vascular lesion associated with acute or chronic gastrointestinal bleeding. It occurs most frequently in the right colon and is extremely rare. Its etiology is unknown, but theories of its pathogenesis have evolved from its similarity to colonic angiodysplasia and the lesion appears to be associated with renal insufficiency. CASE REPORT: Sixty-five-year-old woman with repeated melena and severe anemia due to angiodysplasia in the first portion of the duodenum. The diagnosis was done by upper endoscopy. As the patient presented repeated gastrointestinal bleeding with hemodynamic instability and recurrent anemia, surgery was indicated. At laparotomy the lesion was identified and resected with an Y-en-Roux reconstruction. The patient went on well at the immediate and late (four years postoperative periods with no more recurrent gastrointestinal bleeding. CONCLUSION: Although most of the patients suffering from gastrointestinal angiodysplasia goes on well with conservative management, there is a small portion of them that will need a more aggressive approach, as in this case.RACIONAL: Angiodisplasia duodenal é uma lesão vascular distinta da mucosa intestinal associada com sangramento agudo ou crônico. Embora seja extremamente rara no duodeno, ocorre com maior freqüência no cólon direito. Tem etiologia desconhecida, mas sua patogênese parece semelhante com a do cólon. Em alguns casos está associada à insuficiência renal. RELATO DO CASO: Paciente de 65 anos de idade com episódios repetidos de melena e anemia severa devido à presença de lesão angiodisplásica na primeira porção do duodeno, cujo diagnóstico fôra estabelecido por endoscopia digestiva alta.

The treatment of iron-deficiency anemia with oral iron supplements can present side-effects on the GI tract mucosa including necrosis, ulceration, or ischemia. The particular endoscopic findings and the histopathological exam will establish the diagnosis of erosive gastritis with iron deposits in the gastric mucosa. We present the case of a 14-year-old female admitted in our clinic for upper digestive hemorrhage, nausea, melena, and abdominal pain. Her personal history revealed iron deficiency anemia receiving oral iron supplements for approximately 2 weeks. The laboratory tests at the moment of admission pointed out anemia, increased level of serum iron, increased liver transaminases, a decreased level of ferritin, but with normal levels of both total iron-binding capacity and transferrin. The eso-gastro-duodenoscopy revealed multiple brown deposits on the surface of the gastric mucosa and multiple hemorrhagic lesions, under the aspect of erosions all over the gastric mucosa, but more severe in the antral part, and the histopathological exam confirmed the presence of iron deposits at this level. Iron-pill induced gastritis is a rare, under-diagnosed entity that can be present even at pediatric ages with potential severe clinical impact.

Female patient aged 18 years and 8 months, with diagnosis of hypertrophic gastritis since the age of 10, when she started having sporadic vomiting, weight loss, and anemia (Hb = 5.0 at diagnosis in August 2007). On her first upper gastrointestinal endoscopy (UGE) performed at the Instituto da Crianca (ICr) at HC-FMUSP, in August 2007, it was seem globally hypertrophied and swollen gastric mucosa, with an infiltrative lesion with ill-defined margins. A biopsy confirmed hyperplastic gastritis with a pattern of Menetrier's disease. Outpatient follow-up was initiated at Pediatric Gastroenterology Service of ICr in January 2008, with periodic clinical evaluation and UGE. The patient progressed in the following months with poor appetite and episodes of upper gastrointestinal bleeding and melena, requiring hospitalization in the city of origin and transfusions of blood concentrates. In the following years, she showed less recurrent episodes of bleeding than as seen in the first years after diagnosis, but continued undergoing serial UGEs for disease control and malignant surveillance, maintaining the same macroscopic and microscopic pattern. The patient has been submitted to extensive research for Helicobacter pylori in gastric biopsies, all with negative results, the same occurring with immunophenotyping for cytomegalovirus (CMV). Clinically, she continued to show poor weight gain, but with proper growth and no generalized edema at any time. (author)
Full Text Available Background. To investigate the safety and efficacy of superselective transcatheter arterial embolization (TAE with n-butyl cyanoacrylate (NBCA in treating lower gastrointestinal bleeding caused by angiodysplasia. Methods. A retrospective study was performed to evaluate the clinical data of the patients with lower gastrointestinal bleeding caused by angiodysplasia. The patients were treated with superselective TAE with NBCA between September 2013 and March 2015. Angiography was performed after the embolization. The clinical signs including melena, anemia, and blood transfusion treatment were evaluated. The complications including abdominal pain and intestinal ischemia necrosis were recorded. The patients were followed up to evaluate the efficacy in the long run. Results. Seven cases (2 males, 5 females; age of 69.55±2.25 were evaluated in the study. The embolization was successfully performed in all cases. About 0.2–0.8 mL (mean 0.48±0.19 mL NCBA was used. Immediate angiography after the embolization operation showed that the abnormal symptoms disappeared. The patients were followed up for a range of 2–19 months and six patients did not reoccur. No serious complications, such as femoral artery puncture point anomaly, vascular injury, and intestinal necrosis perforation were observed. Conclusion. For the patients with refractory and repeated lower gastrointestinal hemorrhage due to angiodysplasia, superselective TAE with NBCA seem to be a safe and effective alternative therapy when endoscopy examination and treatment do not work.

Vascular-targeted photodynamic therapy (V-PDT) has been used for several benign vascular diseases. The aim of this pilot study was to demonstrate the potential benefits of VPDT in the treatment of gastric antral vascular ectasia (GAVE). Data from patients with GAVE (n=5) who underwent endoscopic V-PDT were analyzed retrospectively. Pre- and post-V-PDT clinical and endoscopic features, hemoglobin levels, and transfusion requirement were compared. The five GAVE patients received one to four sessions of V-PDT. The hemoglobin levels of all five patients increased steadily following V-PDT. Within 6-48months of follow-up, gastrointestinal bleeding and melena disappeared in all five patients and none of the patients needed a transfusion. Endoscopy examinations showed that the dilated vessels had disappeared without scar formation. No significant side effects or adverse reactions were reported. This preliminary study indicates the good selectivity, safety, and efficacy of V-PDT in the treatment of patients with GAVE. Larger prospective studies are needed to further confirm the feasibility of using V-PDT to treat patients with GAVE. Copyright © 2016. Published by Elsevier B.V.

Gastric polyps are often an incidental finding on upper gastrointestinal endoscopy, with an incidence up to 5%. The majority of gastric polyps are asymptomatic, occurring secondary to inflammation. Prior reviews discussed Helicobacter pylori (H pylori)-associated singular gastric polyposis; however, we present a rare and unusual case of recurrent multiple benign gastric polyposis post H pylori eradication resulting in intermittent gastric outlet obstruction. A 70-year-old independent male, Chinese in ethnicity, with a background of diabetes mellitus, hypertension, and a simple renal cyst presented with a combination of melena, anemia, and intermittent vomiting of partially digested food after meals. Initial gastroscopy was positive for H pylori; thus he was treated with H pylori eradication and proton pump inhibitors. Serial gastroscopy demonstrated multiple sessile gastric antral polyps, the largest measuring 4 cm. Histopathologic examination confirmed a benign hyperplastic lesion. Computed tomography identified a pyloric mass with absent surrounding infiltration or metastasis. A distal gastrectomy was performed, whereby multiple small pyloric polyps were found, the largest prolapsing into the pyloric opening, thus explaining the intermittent nature of gastric outlet obstruction. Such polyps often develop from gastric ulcers and, if left untreated, may undergo neoplasia to form malignant cells. A distal gastrectomy was an effective choice of treatment, taking into account the polyp size, quantity, and potential for malignancy as opposed to an endoscopic approach, which may not guarantee a complete removal of safer margins and depth. Therefore, surgical excision is favorable for multiple large gastric polyps with risk of malignancy.

Full Text Available Metastatic choriocarcinoma is a rare nonseminomatous germ-cell tumor with a characteristic hemorrhagic tendency due to its trophoblastic origin. Gastrointestinal tube involvement is present in less than 5% of cases, and location or therapy of these lesions can be achieved by endoscopy, angiography or surgery. Despite its being a highly curable malignant disease, the ocurrence of gastrointestinal bleeding worsens prognosis. We report a case of metastatic choriocarcinoma which manifested as melaena and was diagnosed by the presence of metastatic lesions in the stomach and right bowel on endoscopy.El coriocarcinoma metastático es una infrecuente tumoración de células germinales con una marcada tendencia hemorrágica debido a su origen trofloblástico. La invasión del tubo digestivo ocurre en menos del 5% de los casos. A pesar de ser una enfermedad maligna con buena respuesta a la quimioterapia, la hemorragia gastrointestinal ensombrece el pronóstico. Presentamos un caso de un paciente de 37 años con un coriocarcinoma diseminado en el que la presentación clínica fue hemorragia digestiva en forma de melenas, encontrándose por endoscopia lesiones metastáticas en estómago y colon derecho.
Diverticulosis of the terminal ileum is very rare. We report a case of diverticulitis of multiple diverticula of the terminal ileum. A 67-year-old Japanese woman consulted to our hospital because of abdominal pain and melena. A blood laboratory revealed severe anemia increased CRP (11.21 mg/dl). The upper and lower gastrointestinal endoscopic examination revealed no significant changes. The colon was free from diverticulum. CT demonstrated two tumors in the small intestine. PET identified a few shadows identical to the tumors detected by CT. The clinical diagnosis was small intestinal tumors, particularly malignant lymphoma. Operation was performed, and it revealed multiple tumor-like masses in the terminal ileum. The ulcers are deep and appeared diverticula. Microscopically, the diverticula were located in the proper muscle and subserosa. The walls of the diverticula were composed of granulation tissue with heavy lymphocytic and neutrophilic infiltration. Diverticular mucosal walls were recognized in some areas. The lymphocytes were free from atypia, and no features of malignant lymphoma were recognized. The pathological diagnosis was severe diverticulitis of multiple diverticula in the terminal ileum.

We report a unique case of intramucosal carcinoma in a tubulovillous adenoma arising from a single diverticulum. Endoscopic mucosal resection (EMR) was carried out successfully and completely with the assistance of laparoscopy. A 71-year-old man was admitted to our hospital because of melena and anemia. Emergent colonoscopy showed diverticulosis in the right-sided colon. However, endoscopy could not exactly detect the bleeding site. A flat elevated polyp was found within a single diverticulum located in the descending colon and diagnosed as an intramucosal carcinoma, as magnifying chromoendoscopy revealed a type IV pit pattern. As his diverticular bleeding repeated, a right-sided hemicolectomy was decided for treatment, the polyp within the diverticulum was also completely removed by EMR with the assistance of laparoscopy. Although a colonic perforation was detected immediately after EMR, the perforation was closed with endoclips intraluminally and also repaired laparoscopically from the serosal side. Histologically, the resected lesion was an intramucosal well-differentiated adenocarcinoma and the surgical margin was free of tumor. PMID:20333800

Upper gastrointestinal (GI) bleeding is a serious complication that sometimes occurs after percutaneous radiologic gastrostomy (PRG). We evaluated the incidence of bleeding complications after a PRG and its management including transcatheter arterial embolization (TAE). We retrospectively reviewed 574 patients who underwent PRG in our institution between 2000 and 2010. Eight patients (1.4%) had symptoms or signs of upper GI bleeding after PRG. The initial presentation was hematemesis (n = 3), melena (n = 2), hematochezia (n = 2) and bloody drainage through the gastrostomy tube (n = 1). The time interval between PRG placement and detection of bleeding ranged from immediately after to 3 days later (mean: 28 hours). The mean decrease in hemoglobin concentration was 3.69 g/dL (range, 0.9 to 6.8 g/dL). In three patients, bleeding was controlled by transfusion (n = 2) or compression of the gastrostomy site (n = 1). The remaining five patients underwent an angiography because bleeding could not be controlled by transfusion only. In one patient, the bleeding focus was not evident on angiography or endoscopy, and wedge resection including the tube insertion site was performed for hemostasis. The other four patients underwent prophylactic (n = 1) or therapeutic (n = 3) TAEs. In three patients, successful hemostasis was achieved by TAE, whereas the remaining one patient underwent exploration due to persistent bleeding despite TAE. We observed an incidence of upper GI bleeding complicating the PRG of 1.4%. TAE following conservative management appears to be safe and effective for hemostasis.

Acute upper gastrointestinal (UGI) bleeding manifests as hematemesis, melena, or hematochezia. Initial management is identical, irrespective of nasogastric (NG) aspirate results. Current practice includes early upper endoscopy. Significantly fewer high-risk bleeding lesions are found on endoscopy in patients with coffee grounds vs. bloody NG aspirates. We present a case series to illustrate that patients with coffee grounds emesis (CGE) often have other unsuspected illnesses that may be overlooked due to preoccupation with the GI bleed. A retrospective chart review of a series of 6 patients presenting with CGE and admitted for upper GI bleeding was performed. All 6 patients were hemodynamically stable at admission. NG lavage showed coffee grounds that cleared easily. None of the patients required blood transfusions during their hospital stay. Endoscopy in 3 of 6 patients failed to find any significant UGI lesions or stigmata of recent bleed. Although patients were admitted for UGI bleeding, the more significant associated diagnoses included acute myocardial infarction, urosepsis, small bowel obstruction, bilateral pulmonary emboli, and acute renal failure. Hemodynamically stable patients presenting with coffee grounds NG aspirate and no fall in hemoglobin/hematocrit should be evaluated for other non-GI bleeding-related conditions even as the GI bleed is being managed.

In this report, we describe two autopsy cases of death due to upper gastrointestinal hemorrhage (Case 1: gastric ulcer, Case 2: aortoduodenal fistula). Postmortem computed tomography (CT) images from both cases revealed pooling of gastric fluid, which contained high attenuation areas, although these images also mirrored the different sources of the gastrointestinal hemorrhage. Fluid collection was observed in the small intestine for both cases, although the high attenuation areas were only remarkable in Case 2. The autopsy in Case 1 revealed a peptic ulcer, with small vessels exposed on the surface of the ulcer. Melena was also observed throughout the intestine, although clotting was only observed inside the stomach. The autopsy in Case 2 revealed diffuse massive clotting from the stomach to the upper portion of the ileum, which was due to a primary aortoduodenal fistula. Given our autopsy findings, the extent of the high attenuation areas in the digestive tract during postmortem CT scanning may be correlated with the speed of the gastrointestinal hemorrhage before death. Carefully evaluating the radiodensity of the gastrointestinal contents during postmortem CT scanning may indicate the primary site of the hemorrhage before the autopsy, thereby facilitating the accurate identification of the cause of death during forensic autopsy.

Polyarteritis nodosa (PAN) is a primary systemic necrotizing vasculitis with diffuse organ involvements, resulting in a high mortality rate due to multiple organ failure. Although the small bowel is the frequently targeted organ of PAN-associated vasculitis, rectal involvement is very rare, and only one case of rectal bleeding has been previously reported. The mortality rate of PAN with gastrointestinal (GI) perforation is reportedly much higher than that of without severe GI involvement. We herein report the first case of rectal perforation due to PAN, successfully managed with an adequate surgical intervention. A 66-year-old woman with PAN had abdominal pain and melena with guarding. Computed tomography scan showed abdominal free air and bubbles in the rectal hematoma. We diagnosed it acute peritonitis, and emergency surgery was performed. After removing rectal hematoma and necrotic tissue, a huge lack of rectal wall spreading to the pelvirectal space was observed. In order to totally remove the necrotic tissue, abdominoperineal resection was needed. Together with histopathological examinations which showed neutrophils and fibrinous necrosis, we finally diagnosed rectal perforation due to PAN. At 19-month follow-up after surgery, she was still healthy with a stable disease of PAN. We herein reported the first case of successfully managed rectal perforation due to PAN. Early adequate surgical resection may be important for the case with rectal perforation.

To determine clinical, clinicopathologic, radiographic, ultrasonographic, and coagulation abnormalities in dogs in which acute pancreatitis was fatal. Retrospective study. 70 dogs. History, clinical signs, and physical examination findings at the time of initial evaluation at the veterinary teaching hospital; results of pretreatment laboratory tests, abdominal radiography, and ultrasonography; and histologic abnormalities were obtained from medical records. Clinical signs included anorexia, vomiting, Weakness, diarrhea, polyuria and polydipsia, neurologic abnormalities, melena, weight loss, hematemesis, and passage of frank blood in feces. At the time of initial examination at the veterinary teaching hospital, 68 (97%) dogs were dehydrated, 18 (26%) were icteric, 22 (32%) were febrile, 40 (58%) had signs of abdominal pain, and 30 (43%) were classified as overweight or obese. Most dogs had leukocytosis, neutrophilia with a left shift, and thrombocytopenia. Various serum biochemical abnormalities were identified, including hypoglycemia, azotemia, hypercalcemia and other electrolyte abnormalities, hypoalbuminemia, high hepatic and pancreatic enzyme activities, hypercholesterolemia, and lipemia. For 17 of 28 (61%) dogs, results of coagulation function tests were abnormal. Results of abdominal ultrasonography and radiography were consistent with a diagnosis of acute pancreatitis in 23 of 34 (68%) and 10 of 41 (24%) dogs, respectively. For 2 dogs, results of abdominal ultrasonography were not suggestive of acute pancreatitis, but results of abdominal radiography were. Clinical signs and results of clinicopathologic tests are inconsistent. Abdominal ultrasonography may be valuable in the diagnostic evaluation of dogs suspected to have acute pancreatitis

Full Text Available Background: Copper sulfate ingestion is a relatively popular method for committing suicide in Indian subcontinent. It causes a high mortality rate, and so a growing concern has been raised to identify the severe alarming signs suggestive of poor prognosis and to improve treatment approaches. Case report: A 22-year-old unmarried man working as a painter was found unconscious at his friend residence. The patient developed hypotension, hemorrhagic gastroenteritis with hematemesis and melena, renal and hepatic failure, severe metabolic acidosis and intravascular hemolysis during admission at hospital. His signs were refractory to treatment with fluid replacement therapy, vasoactive drugs, antiemetic drugs, ranitidine, furosemide, methylene blue and 2,3 dimercaptopropane-1-sulphonate. He died six hours post-admission. In post-mortem examinations, there were multiple sub-pleural and sub-epicardial hemorrhages and the gastrointestinal mucosa was congested, hemorrhagic, and greenish blue in color. The liver, on histological examination, showed sub-massive hepatic necrosis. On toxicological analyses, copper sulfate was detected in preserved viscera and results for other heavy metals were negative. Conclusion: Hypotension, cyanosis, uremia and jaundice can be considered as signs of poor prognosis in copper sulfate poisoning. Copper sulfate ingestion is life-threatening due to its deleterious effects on the upper GI, kidneys, liver and blood. Having no time to waste, aggressive treatments should be immediately instituted and signs of poor prognosis should be kept in mind.

To describe chelation therapy with d-penicillamine for treatment of zinc toxicosis in a dog. A 1.5-year-old intact female Maltese dog weighing 2.7 kg was presented with acute, progressive anorexia, lethargy, pigmenturia, and melena. The owner reported that the dog had ingested a hook from a dog leash made of a zinc-based alloy 9 days prior. A blood transfusion was administered and an abdominal radiograph revealed a metal-dense foreign body in the stomach. Laboratory findings revealed a serum zinc concentration of 1845.12 μg/dL (reference interval, 70-200 μg/dL) and a decreased hematocrit that remained low despite removal of the zinc foreign body. On day 3, another blood transfusion was performed and d-penicillamine therapy was instituted. After the administration of d-penicillamine, the clinical signs and hemogram progressively improved and the dog was discharged 2 days later. On day 9 after initial presentation, the hematocrit and platelet values were within normal limits and the serum zinc concentration was 280.16 μg/dL. This case demonstrates the use of d-penicillamine in the treatment of zinc toxicosis. Serum zinc concentration appeared to decline more rapidly after administration of d-penicillamine than before chelation therapy. This is the first report to evaluate serial serum zinc concentrations before and during chelation therapy with d-penicillamine. © Veterinary Emergency and Critical Care Society 2015.

Pulmonary pleomorphic carcinoma is an uncommon malignant lesion of the lung. A chest radiograph of 53-year-old man who was suffering from a cough revealed a well-defined mass-like opacity with a broad base on the pleura at the apico-posterior segment of the right upper lobe of the lung. The subsequent chest computed tomography (CT) scan demonstrated an inhomogeneous enhancing mass with central low-attenuation in the right upper lobe. A lobectomy was performed and the mass was determined to be a pleomorphic carcinoma with visceral pleura invasion. Forty days after the operation, the patient complained of melena and an abdominal CT revealed an intraluminal and extraluminal protruding mass around the prepyloric antrum and duodenal bulb. The mass was removed by en-block surgery and diagnosed as metastatic pleomorphic carcinoma from the lung. Previous articles reported a median survival time of 3–10 months for pleomorphic carcinoma, but in this case, the patient has continued to survive, 11 years after surgery. Chest and abdominal CTs have revealed no evidence of tumor recurrence or metastasis.

Full Text Available Intravenous bevacizumab decreased mucosal bleeding in some patients with hereditary hemorrhagic telangiectasia (HHT. We treated a 47-year-old male who had HHT, severe epistaxis, and gastrointestinal bleeding, alcoholic cirrhosis, and portal hypertension with intravenous bevacizumab 2.5 mg/kg every 2 weeks. We tabulated these measures weekly during weeks 1–33 (no bevacizumab; 34–57 (bevacizumab; and 58–97 (no bevacizumab: hemoglobin (Hb levels; platelet counts; units of transfused packed erythrocytes (PRBC units; and quantities of iron infused as iron dextran to support erythropoiesis. We performed univariate and multivariable analyses. We sequenced his ENG and ACVRL1 genes. Epistaxis and melena decreased markedly during bevacizumab treatment. He reported no adverse effects due to bevacizumab. Mean weekly Hb levels were significantly higher and mean weekly PRBC units and quantities of intravenous iron were significantly lower during bevacizumab treatment. We performed a multiple regression on weekly Hb levels using these independent variables: bevacizumab treatment (dichotomous; weekly platelet counts; weekly PRBC units; and weekly quantities of intravenous iron. There was 1 positive association: (bevacizumab treatment; p = 0.0046 and 1 negative association (PRBC units; p = 0.0004. This patient had the novel ENG mutation E137K (exon 4; c.409G→A. Intravenous bevacizumab treatment 2.5 mg/kg every 2 weeks for 24 weeks was well-tolerated by a patient with HHT due to ENG E137K and was associated with higher weekly Hb levels and fewer weekly PRBC units.
Full Text Available Purpose. We report a novel technique which aided recanalization of an occluded portal vein for transjugular intrahepatic portosystemic shunt (TIPS creation in a patient with symptomatic portal vein thrombosis with cavernous transformation. Some have previously considered cavernous transformation a contraindication to TIPS. Case Presentation. 62-year-old man with chronic pancreatitis, portal vein thrombosis, portal hypertension and recurrent variceal bleeding presents with melena and hematemesis. The patient was severely anemic, hemodynamically unstable, and required emergent portal decompression. Attempts to recanalize the main portal vein using traditional transjugular access were unsuccessful. After percutaneous transhepatic right portal vein access and navigation of a wire through the occluded main portal vein, an angioplasty balloon was inflated at the desired site of shunt takeoff. The balloon was targeted and punctured from the transjugular approach, and a wire was passed into the portal system. TIPS placement then proceeded routinely. Conclusion. Although occlusion of the portal vein increases difficulty of performing TIPS, it should not be considered an absolute contraindication. We have described a method for recanalizing an occluded portal vein using a combined transhepatic and transjugular approach for TIPS. This approach may be useful to relieve portal hypertension in patients who fail endoscopic and/or surgical therapies.

Endoscopic therapy has been demonstrated to be effective in achieving hemostasis for bleeding peptic ulcers. Thermal coagulation is one of the most commonly used methods, with a high success rate. Recently, endoscopic submucosal dissection for early gastric carcinoma was developed and hemostasis with soft coagulation using hemostatic forceps was introduced. The aim of this study was to compare the hemostatic efficacy of soft coagulation with heater probe thermocoagulation for peptic ulcer bleeding. Patients who visited our hospital with hematemesis or melena underwent emergency endoscopy. Inclusion criteria were presentation with an actively bleeding ulcer, a nonbleeding visible vessel, or an adherent clot. Patients were excluded if they were unwilling to give written informed consent or had a bleeding gastric malignancy. Patients were randomized to receive endoscopic hemostasis with soft coagulation (Group S) or heater probe thermocoagulation (Group H). The primary endpoint was the primary hemostasis rate and secondary endpoints were rebleeding rate, complications, and the procedure time. Between May 2010 and February 2012, a total of 111 patients (89 gastric ulcers and 22 duodenal ulcers) were enrolled. Primary hemostasis was achieved in 54 patients (96%) in Group S and 37 (67%) in Group H (Pheater probe thermocoagulation for achieving hemostasis.

Full Text Available Background - Upper gastrointestinal bleeding implies significant clinical and economic repercussions. The correct establishment of the latest therapies for the upper gastrointestinal bleeding is associated with reduced in-hospital mortality. The use of clinical pathways for the upper gastrointestinal bleeding is associated with shorter hospital stay and lower hospital costs. Objective - The primary objective is the development of a clinical care pathway for the management of patients with upper gastrointestinal bleeding, to be used in tertiary hospital. Methods - It was conducted an extensive literature review on the management of upper gastrointestinal bleeding, contained in the primary and secondary information sources. Results - The result is a clinical care pathway for the upper gastrointestinal bleeding in patients with evidence of recent bleeding, diagnosed by melena or hematemesis in the last 12 hours, who are admitted in the emergency rooms and intensive care units of tertiary hospitals. In this compact and understandable pathway, it is well demonstrated the management since the admission, with definition of the inclusion and exclusion criteria, passing through the initial clinical treatment, posterior guidance for endoscopic therapy, and referral to rescue therapies in cases of persistent or rebleeding. It was also included the care that must be taken before hospital discharge for all patients who recover from an episode of bleeding. Conclusion - The introduction of a clinical care pathway for patients with upper gastrointestinal bleeding may contribute to standardization of medical practices, decrease in waiting time for medications and services, length of hospital stay and costs.
Full Text Available We report a rare case of angiosarcoma involving the gastrointestinal tract, liver, spleen, pancreas, kidney, lung and vertebrae, as well as bulky dissemination in the pleuroperitoneal membranes. A 72-year-old man with no history of illness became aware of melena. Laboratory findings revealed anemia, and upper gastrointestinal endoscopy revealed multiple reddish nodules in the stomach and duodenum. However, biopsy specimens showed no evidence of histological features. Computed tomography and fluorodeoxyglucose positron emission tomography showed space-occupying lesions in the spleen, liver and vertebrae. Angiosarcoma was diagnosed by endoscopic ultrasound and fine needle aspiration biopsy of the spleen and repeated endoscopic biopsy of the stomach. We performed laparoscopic splenectomy to avoid rupture of the involved spleen. Due to continuous gastrointestinal bleeding, double balloon endoscopy was performed and multiple bleeding lesions were detected throughout the small intestine. Surgical hemostasis was performed by partial enterectomy, but anemia continued to worsen. Therefore, we conducted transcatheter arterial embolization. Despite attempting several modalities and frequent daily blood transfusion, the anemia did not improve, and the patient expired due to hemorrhagic shock. Subsequent autopsy revealed the cause of death as rupture and bleeding due to disseminated involvement of the small intestine.

Although the risk of bleeding after endoscopic ultrasound-guided fine needle aspiration (EUS-FNA) is low, the safety of EUS-FNA in patients prescribed antithrombotic agents is unclear. Therefore, this study evaluated the incidence of bleeding after EUS-FNA in those patients. Between September 2012 and September 2015, patients who were prescribed antithrombotic agents underwent EUS-FNA at 13 institutions in Japan were prospectively enrolled in the study. The antithrombotic agents were managed according to the guidelines of the Japanese Gastrointestinal Endoscopy Society. The rate of bleeding events, thromboembolic events and other complications within 2 weeks after EUS-FNA were analyzed. Of the 2,629 patients who underwent EUS-FNA during the study period, 85 (62 males; median age, 74 years) patients were included in this stduy. Two patients (2.4%; 95% confidence interval [CI], 0.6% to 8.3%) experienced bleeding events. One patient required surgical intervention for hemothorax 5 hours after EUS-FNA, and the other experienced melena 8 days after EUS-FNA and required red blood cell transfusions. No thromboembolic events occurred (0%; 95% CI, 0.0% to 4.4%). Three patients (3.5%; 95% CI, 1.2% to 10.0%) experienced peri-puncture abscess formation. The rate of bleeding after EUS-FNA in patients prescribed antithrombotic agents might be considerable.

Portal cavernoma is a venous vascular anomaly characterized by the formation of a network of veins whose caliber is increased and carrying portal blood. It is due to a thrombotic and always chronic occlusion of the extra-hepatic portal venous system. This is one of the most common causes of portal hypertension in children. Its severity is mainly associated with an high risk of gastrointestinal haemorrhage. Very few cases have been described mainly in African literature. We report the case of a 4-year old boy admitted with very abundant haematemesis, melena and dizziness associated with anemic syndrome on examination. Laboratory tests showed severe microcytic hypochromic anemia with normal renal and hepatic function. Gastrointestinal endoscopy showed esophageal varices (grade III) with red signs. Abdominal ultrasound showed portal vein formation resulting in the classic "spiderweb", in favor of a cavernoma. Abdominal CT scan confirmed portal cavernoma associated with portal hypertensive syndrome and vascular anomaly like an ectopic splenic vein anastomosis with the trunk formed by the gonadal vein and the inferior mesenteric vein. Therapeutic approach was based on blood transfusion and beta-blocker treatment. Portal cavernoma can be a major complication of vascular malformations often unknown. In case of gastrointestinal haemorrhage in children, diagnosis should be suspected. Its management requires early treatment and should be adapted to the patient's condition in order to prevent a fatal evolution.

Full Text Available Abstract Introduction Ischemic bowel disease comprises both mesenteric ischemia and colonic ischemia. Mesenteric ischemia can be divided into acute and chronic ischemia. These are two separate entities, each with their specific clinical presentation and diagnostic and therapeutic modalities. However, diagnosis may be difficult due to the vague symptomatology and subtle signs. Case presentation We report the case of a 68-year-old Caucasian woman who presented with abdominal discomfort, anorexia, melena and fever. A physical examination revealed left lower quadrant tenderness and an irregular pulse. Computed tomography of her abdomen as well as computed tomography enterography, enteroscopy, angiography and small bowel enteroclysis demonstrated an ischemic jejunal segment caused by occlusion of a branch of the superior mesenteric artery. The ischemic segment was resected and an end-to-end anastomosis was performed. The diagnosis of segmental small bowel ischemia was confirmed by histopathological study. Conclusion Mesenteric ischemia is a pathology well-known by surgeons, gastroenterologists and radiologists. Acute and chronic mesenteric ischemia are two separate entities with their own specific clinical presentation, radiological signs and therapeutic modalities. We present the case of a patient with symptoms and signs of chronic mesenteric ischemia despite an acute etiology. To the best of our knowledge, this is the first report presenting a case of acute mesenteric ischemia with segmental superior mesenteric artery occlusion.

AIM: To investigate acute nonvariceal bleeding in the upper gastrointestinal (GI) tract and evaluate the effects of endoscopic hemoclipping. METHODS: Sixty-eight cases of acute nonvariceal bleeding in the upper GI tract were given endoscopic treatment with hemoclip application. Clinical data, endoscopic findings, and the effects of the therapy were evaluated. RESULTS: The 68 cases (male:female = 42:26, age from 9 to 70 years, average 54.4) presented with hematemesis in 26 cases (38.2%), melena in nine cases (13.3%), and both in 33 cases (48.5%). The causes of the bleeding included gastric ulcer (29 cases), duodenal ulcer (11 cases), Dieulafoy’s lesion (11 cases), Mallory-Weiss syndrome (six cases), post-operative (three cases), post-polypectomy bleeding (five cases), and post-sphincterotomy bleeding (three cases); 42 cases had active bleeding. The mean number of hemoclips applied was four. Permanent hemostasis was obtained by hemoclip application in 59 cases; 6 cases required emergent surgery (three cases had peptic ulcers, one had Dieulafoy’s lesion, and two were caused by sphincterotomy); three patients died (two had Dieulafoy’s lesion and one was caused by sphincterotomy); and one had recurrent bleeding with Dieulafoy’s lesion 10 mo later, but in a different location. CONCLUSION: Endoscopic hemoclip application was an effective and safe method for acute nonvariceal bleeding in the upper GI tract with satisfactory outcomes. PMID:19750577

Intra-arterial infusion of yttrium-90 (Y-90) microspheres is locoregional radiation therapy for unresectable hepatic neoplasms. Literature on GI complications of this novel therapy is sparse. Clinically and pictorially characterize selective internal radiation therapy (SIRT)-induced GI injury and review the published literature. Retrospective chart analysis. Single-center tertiary referral community hospital. One hundred three patients treated with SIRT for hepatic neoplasms between 2006 and 2008. SIRT for unresectable hepatic neoplasms followed by upper endoscopy with biopsy in symptomatic patients. GI ulcers after SIRT. Five patients with suspected GI injury after SIRT were identified. Significant postprocedural symptoms included nausea/vomiting, odynophagia, hematemesis, and melena. Radiation ulcers occurred mostly in the gastric antrum, pylorus, and duodenum. Biopsy specimens of ulcer margins in 4 patients showed pathognomonic radiation microspheres. Angiographic review of the fifth patient revealed a previously unrecognized arterial branch supplying the corresponding region of GI ulceration noted on endoscopy. Small retrospective study and follow-up limited by terminal disease states in most patients. The reported incidence of GI complications after SIRT for hepatic neoplasia varies from 3% to 24% of patients. Incidence can be minimized by strict adherence to published SIRT protocols. Diagnosis requires a high degree of clinical suspicion along with endoscopy and biopsy of ulcer margins. Characteristic radiation microspheres in biopsy specimens are pathognomonic. Gastroenterologists and pathologists must be cognizant of this complication.

Neuroendocrine tumors (NETs) are a heterogeneous group of neoplasms composed of cells containing dense-core neuroendocrine secretory granules in their cytoplasm. NETs of the esophagus are exceedingly uncommon, with a parallel absence of data published on clinical features, prognosis, and proposed treatment strategies. As relevant classification is not well-established, knowledge acquired in NETs of lung and gastrointestinal sites usually guides esophageal NET management. Associated subtypes are divided based upon shared neuroendocrine features into small and large cell NET, typical and atypical carcinoid. Common presenting symptoms include dysphagia, abdominal discomfort, weight loss, melena, and on occasion, signs of carcinoid syndrome. Endoscopic findings describe a polypoid, nodular elevated lesion with an overlying surface depicted as mostly smooth and glistening. Disease metastasis is assessed using anatomical imaging, including computed tomography (CT), endoscopic ultrasonography (EUS), and positron emission tomography (PET)-CT. Prognosis is influenced by the extent of lymph node metastasis and potential lymphovascular invasion. Furthermore, proliferative activity, estimated using mitotic count or Ki-67 immunostaining, has been suggested as a significant prognostic parameter. Therapeutic approach depends on clinical staging. Nevertheless, currently, a specific treatment algorithm for esophageal NETs has not been elucidated. Endoscopic resection has been proposed in NETs less than 1 cm in size with absence of regional lymph node metastasis, while surgical excision combined with adjuvant chemotherapy remains the treatment of choice.

The patient was a 72-year-old female who underwent radiation therapy following surgical treatment for an ovarian tumor in 1963. Radiation therapy resulted in chronic radiodermatitis which has persisted since then. Twenty-five years after radiation therapy, painful indurative erythema appeared on her leoins (the site of irradiation) accompanied by fever. Histologically, acanthosis, edema and capillary dilatation in the upper dermis, amorphous collagen fibers and scarcity of vasculature in the deep dermis were observed. We found no mitosis but did observe swollen keratinocytes in the epidermal layer. The patient did not respond to antibiotics; however, the administration of oral steroids gradually alleviated the fever and local symptoms. Steroids could not be completely discontinued; she was given low-dose steroids for maintenance of remission. We speculated that the acute inflammatory reaction which was superimposed on the patient's chronic radiodermatitis constituted the earliest signs of malignant transformation. Intermittent bloody stools due to radiation colitis had been present since 3 years before, but after administration of steroids, melena was no longer seen. (author).

Reflux Esophagitis is a common complaint from the upper gastrointestinal tract with a figured out prevalence of about 2%. Therapeutic results in this pathology have been unsatisfactory. To compare lansoprazole and omeprazole therapeutic effects in patients with reflux esophagitis. A clinical, double-blinded, balanced survey was randomly designed with patients who would daily receive 30 mg lansoprazole (Group A) or 20 mg omeprazole (Group B) during a 4-week period. All patients were submitted to endoscopy and biopsy both at the beginning and at the end of the survey. Ten patients in each group were treated without any significant differences in sex, age, nicotinism, alcoholism, AINES ingestion, development time, pain regurgitations, pyrrosis, hematemesis, dysphagia, melena, nausea or vomiting, and esophagitis degree. A complete cure in 8/10 (omeprazole) and 7/10 (lansoprazole) patients was obtained (p = n.s.). However, the histological results of the biopsy at the end of the four-week period proved to be a failure in 4/10 (omeprazole) and in 5/10 (lansoprazole) patients (p = n.s.). The endoscopy and clinical result at the end of the study were similarly effective; but not so the histological damage to the esophagus, which continues to be important. The use of bomb inhibitors in esophagitis by reflux is advisable. Future surveys must assess the average time of treatment for the disappearance of the histologic lesion.

Surgery is one of the modalities of treatment of portal hypertension with bleeding esophageal varices. Between 1992 and 2003, a total of 33 patients with esophageal varices secondary to hepatic or pre-hepatic causes of portal hypertension underwent proto-azygeal disconnection surgery at Tikur Anbessa Hospital, Addis Ababa University. Twenty-five, (69. 7%) were men and 8 (24.3%) were women. Their age ranged between 13 and 54 years with a mean age of 24.3 years. Eighty two percent of the patients had hematemesis and melena. Thirty-two, (97%) patients had splenomegaly and of these; 27 (84%) had splenomegaqly with hyperslenism. Twenty-one, (63.6%) and 12 (36.6%) patients had child's A and B functional class, respectively. None of the patients was in class C. The condition of the liver as assessed macroscopically at surgery showed portal fibrosis in 22 (66.7%), cirrhosis in 3 (9.1%) and normal liver in 8 (24.2%) patients. There was no significant correlation between variceal bleeding episode and type of liver pathology. Four patients (12%) died after surgery and re-bleeding occurred in one (3%) patients. Porto-azygeal disconnection surgery can be done safely in patients with esophageal varices and good liver function in order to prevent further bleeding episode.

Two percent of gastrointestinal hemorrhages are caused by Dieulafoy's lesions, which are located in duodenum in only 15% of cases. There are no recommendations regarding the prime endoscopic treatment technique for this condition. A 61-year-old woman presented with melena without signs of hemodynamic instability. During an urgent upper endoscopy, blood oozing from the normal mucosa of the duodenum was seen and this was classified as a Dieulafoy's lesion. A mini-loop was opened at the rim of a transparent ligation chamber, at the end of the endoscope, and after aspiration of the lesion, closed and detached. Complete hemostasis was achieved without early or postponed complications. In every day clinical practice, mini-loop ligation is rarely used because of possible complications, such as site ulceration, organ perforation, re-bleeding and possible inexperience of the operator. To the best of our knowledge this is the first case of successful treatment of bleeding duodenal Dieulafoy's lesion by mini-loop ligation.
Full Text Available Dengue is a viral disease that is mediated by a mosquito, which causes morbidity and mortality. Viruses can increase vascular permeability which can lead to hemorrhagic diathesis or disseminated intravascular coagulation (DIC known as dengue hemorrhagic fever (DHF. In Indonesia, dengue hemorrhagic fever (DHF are caused by dengue virus infection which was found to be endemic accompanied by an explosion of extraordinary events that appear at various specified period. The diagnosis of dengue is determined based on the criteria of the World Health Organization (WHO, 1999, which are sudden high fever accompanied by a marked tendency to hemorrhage positive tourniquet test, petechiae, ecchymosis, purpura, mucosal hemorrhagic, hematemesis or melena and thrombocytopenia. The problem that still exists today is the mechanism of thrombocytopenia in patients with varying degrees of dengue involving levels of vWF (von Willebrand factor and prostaglandin I2 (PGI2 can not be explained. The mechanism of hemorrhagic in dengue virus infections acquired as a result of thrombocytopenia, platelet disfunction decreased coagulation factors, vasculopathy with endothelial injury and disseminated intravascular coagulation (DIC.

Objective: To determine the diagnostic value of CT in acute mesenteric infarction (AMI). Methods: Ten patients with mesenteric infarction (6 male, 4 female, average age 67.2 years old) were analysed from April 2003 to September 2004, whose symptoms include abdominal pain, melena, nausea and vomiting, etc. Nine cases were confirmed by surgery and pathology except one diedimmediately after CT scan. They included superior mesenteric arterial (SMA) thrombosis (n=4), superior mesenteric venous (SMV) thrombosis (n=5) and inferior mesenteric venous (IMV) thrombosis (n=1). Except one routine CT scan, all the other cases were performed by contrast-enhanced CT examination. Results: The direct sign of acute mesenteric infarction in CT images was filling defect in mesentery vessels (n=8). The indirect signs included dilatation of bowl loops (n=4), bowel wall thickening (n=6), the paper-thin wall sign (n=4), mesenteric stranding (n=5), mesenteric haziness (n=3), pneumatosis of bowel wall (n=2), portal veno gas (n=1) and ascites (n=3). Conclusion: Computed tomography is sensitive to acute mesenteric infarction and is valuable in diagnosis. (authors)

Bleeding ectopic small bowel varices pose a clinical dilemma for the physician, given their diagnostic obscurity and the lack of evidence-based medicine to guide therapy. They often occur in the context of portal hypertension, secondary to either liver disease or extrahepatic causes. Rarely is their presence associated with chronic superior mesenteric vein thrombosis and hereditary coagulopathies. A 74-year-old white woman, with a heterozygous Factor V Leiden mutation and no underlying liver disease or portal hypertension, presented over the course of 13 months for recurrent episodes of melena and per rectal bleeding. An initial endoscopy showed a clean-based chronic gastric ulcer, while colonoscopies showed multiple, non-bleeding angioectasias which were treated with argon plasma coagulation. Subsequent video capsule endoscopy and double balloon enteroscopy revealed red wale marks overlying engorged submucosal veins in her distal ileum, consistent with ectopic varices. A chronic superior mesenteric vein thrombus, found via computed tomography venogram, was the cause of the ileal varices. She underwent curative surgical resection of the affected bowel, with no re-bleeding episodes 17 months post-surgery, despite needing lifelong anticoagulation for recurrent venous thromboembolisms. Clinicians should consider ectopic varices in patients who present with obscure gastrointestinal bleeding, even in the absence of portal hypertension or liver disease. In those with a known thrombophilia, patients should be screened for splanchnic thrombosis, which may precipitate ectopic varices.
Full Text Available Herbal medicine is usually safe and popular in Iranian communities. Peppermint herbal products may interact with warfarin, which is an essential lifelong drug used in patients with prosthetic heart valves. Herein, we report a case of possible interaction between warfarin and peppermint herbal tea.We described a 68-year-old woman who was on warfarin treatment due to bileaflet mechanical aortic valve, and mitral valve replacement presented with severe dyspnea in the setting of large obstructive prosthetic mitral valve thrombosis diagnosed by echocardiography. Therefore, cardiac surgery was conducted in the emergent setting. Warfarin was started the day after the procedure. She developed melena with a volatile and elevated international normalized ratio (INR of 4.8 and prothrombin time > 30 s on the 7th post-operation day. She reported no changes in drug or dietary habits except for drinking high amounts of peppermint tea the day before. After the discontinuation of warfarin and medical consultation for gastrointestinal bleeding, the INR level decreased to 1.8 within two days.Consumption of peppermint herbal products are usually safe; however, caution should be taken with patients under warfarin treatment. Full disclosure for patients on anticoagulant treatment is necessary before discharge and during clinical follow-up

Although the gastrointestinal tract is a fairly frequent site of melanoma metastases, reports of small bowel intussusception caused by melanoma are very rare. We report the case of a 77-year-old man who was admitted to our hospital with epigastric pain, melena and anaemia. After clinical examination, laboratory evaluation and radiological work-up the diagnosis of a jejunal intussusception was made. Exploratory laparoscopy revealed a large tumour arising from the jejunum, approximately 20 cm distal to the angle of Treitz. Small bowel resection with an end-to-end anastomosis was performed. Histological examination showed an intestinal melanoma. There are different theories concerning the origin of malignant melanoma in the small bowel. Although the small and large intestines normally contain no melanocytes, these cells have occasionally been found in the alimentary and respiratory tracts and even in lymph nodes, which supports the theory of a primary origin of melanoma at these sites. Since this was a solitary intestinal lesion and there was no history of cutaneous melanoma, we conclude that this could be an example of a very rare primary melanoma of the small intestine.

Full Text Available Diarrhea, melena, and lower abdominal pain developed in a male in his 20s and colonoscopy showed pancolitis-type severe ulcerative colitis (UC. Treatment was initiated with 4,000 mg of 5-aminosalicylic acid and 60 mg/day of prednisolone, but the symptoms and inflammatory reaction worsened with prednisolone dose reduction. Tacrolimus was added to the treatment, which subsequently induced remission. Serial colonoscopies during the treatment showed improvement in ulcer and mucosal edema throughout the entire large intestine, but a new solitary round ulcer appeared at the end of the ileum. Since no signs of Behçet’s disease were noted, it was considered as a simple ulcer, a complication of UC. Tacrolimus treatment was continued based on continued improvement in clinical features and colonic mucosa, excluding the end of the ileum. Colonoscopy at 6 months after initiation of tacrolimus showed healing of the large intestinal mucosa, although mild congestion was still noted. The solitary round ulcer at the end of the ileum improved to a small erosion. We report the improvement of a simple ulcer that developed during tacrolimus treatment.

Full Text Available An unusual cause of upper gastrointestinal bleeding is described in a previously healthy 45-year-old man who was admitted to hospital with weakness and fatigue, and had experienced an episode of melena two days before admission. His medical and surgical history was unremarkable. Upon admission to hospital, he showed evidence of iron-deficiency anemia, with a hemoglobin concentration of 61 g/L (normal range 135 to 175 g/L, a mean corpuscular volume of 73 fL (normal range 85.0 to 95.0 fL and a ferritin concentration of 1.0 µg/L (normal range in males 15 to 400 µg/L. Upper gastrointestinal endoscopy revealed a 3.5 cm ulcerated submucosal mass in the third portion of the duodenum, for which mucosal biopsies were nondiagnostic. A subsequent endoscopic ultrasound revealed a 2.7×4.0 cm hyperechoic, cystic, submucosal tumour in the third portion of the duodenum. Endoscopic ultrasound-guided fine needle aspiration revealed no malignant cells. The patient eventually underwent a resection of the third portion of his duodenum. Surgical pathology revealed that this tumour was a Brunner’s gland hamartoma, 4.5 cm in its greatest dimension.

Gangliocytic paragangliomas are rare tumors that almost exclusively occur within the second portion of the duodenum. Although these tumors generally have a benign clinical course, they have the potential to recur or metastasize to regional lymph nodes. The case report presented here describes a 57-year-old female patient with melena, progressive asthenia, anemia, and a mass in the second-third portion of the duodenum that was treated by local excision. The patient was diagnosed with a friable bleeding tumor. The histologic analysis showed that the tumor was a 4 cm gangliocytic paraganglioma without a malignant cell pattern. In the absence of local invasion or distant metastasis, endoscopic resection represents a feasible, curative therapy. Although endoscopic polypectomy is currently considered the treatment of choice, it is not recommended if the size of the tumor is > 3 cm and/or there is active or recent bleeding. Patients diagnosed with a gangliocytic paraganglioma should be closely followed-up for possible local recurrence. PMID:26328037

The authors described clinical pictures and those treatments of 40 patients with complications of the lower part of the large intestine resulting from radiotherapy for cancer of the uterus, ovarium or the penis. As the radiotherapy, 60 Co-telecobalt (6,000-16,000R) and 60 Co-needle (1,000-8,568 mch) intracavitary irradiation were used alone or in combination. Findings in the complications of the lower part of the large intestine were classified into Grade I (13 cases), II (14), III (14), and IV (4) according to Sherman. The prodromal symptoms of the complications appeared in 2-6 months following the irradiation in more than a half of the patients, and it appeared within a year in most of the patients. Most of the patients complained about melena, anemia, proctagra, tenesmus and diarrhea. In the cases of Grade III, the symptoms of ileus such as constipation, abdominal distention, and abdominal pain appeared. Internal treatment was given principally, and preternal anus was made when frequent blood transfusion was required. Fourteen cases of those in Grade I and II recovered within 1-3 years. The cases which received proctostomy, including those who had bleeding, stricture and fistulation, had favorable prognosis. This result suggested that the radiotherapy for intra-pelvic cancer should be controlled to prevent further development of the complications in the rectum beyond Grade I. (Serizawa, K.)
Full Text Available GIST tumors is very unusual in the young and middle aged and a high index of suspicion is needed for the diagnosis in young patients who present with upper gastrointestinal bleeding. Appropriate imaging such as a Computed tomographic scan (CT scan may identify this tumor which may easily be misdiagnosed as a bleeding Peptic Ulcer Disease in the young. We present a case of a healthy 38 year old man with no alcohol use who presented with epigastric pain and melena and subsequent torrential bleeding uncontrolled during endoscopy necessitating an emergency exploratory laparotomy by the general surgery team. The bleeding intraluminal component of the tumor with gross splenic and pancreatic involvement was identified and surgical management consisted of a wedge resection of the greater curvature of the stomach incorporating the tumor and the spleen with successful dissection of the tumor off the tail of the pancreas. Histology was positive for C-KIT and DOG-1 markers. Postoperative course was uneventful and he is presently on Imatinib Mesylate.
Full Text Available A 62-year-old man with a history of mechanical aortic valve insertion and ascending aorta replacement in 1997 presented to his family doctor in August 2004 with a two-week history of melena after recently returning from a six-month vacation in Mexico. The patient had no other abdominal complaints. He took warfarin but did not take nonsteroidal anti-inflammatory agents, acetylsalicylic acid or alcohol. The patient had no history of liver or peptic ulcer disease. He had lost 7 kg over the past month, but did not complain of fever or night sweats. On physical examination, vital signs were normal, the second heart sound was mechanical, and there were no abnormal findings. Laboratory investigations showed a borderline microcytic anemia (hemoglobin 76 g/L; mean corpuscular volume 79 fL; mean corpuscular hemoglobin concentration 323 g/L, a therapeutic international normalized ratio (2.6 and an elevated creatinine level (112 µmol/L. His stool was positive for occult blood, although the ferritin level was high (623 µg/L. Other routine blood work was normal. The patient was admitted to hospital for investigation of the anemia.

Full Text Available INTRODUCCIÓN. El sangramiento digestivo alto continúa siendo un problema de salud, y junto al abdomen agudo, las heridas y los traumatismos es prácticamente la razón de ser de una guardia de cirugía. MÉTODOS. Se realizó un estudio observacional, descriptivo y de corte transversal, cuyo universo estuvo constituido por todos los pacientes con este diagnóstico ingresados en el Hospital Docente Clinicoquirúrgico «Joaquín Albarrán», entre enero del 2006 y diciembre del 2007 (2 años. RESULTADOS. Las edades más frecuentes estuvieron entre los 70 y 79 años, y fue más frecuente el sexo masculino y el antecedente de enfermedad cardiovascular. La melena fue la principal manifestación clínica. La endoscopia solo se realizó en el 25,16 % de los casos, y en ella se observó principalmente duodenitis y gastritis. Como medidas terapéuticas más comunes se practicaron la hidratación y el uso sondas de Levine. Solo el 20,48 % de los pacientes recibieron tratamiento contra Helicobacter pylori. La estadía hospitalaria promedio fue de 6 días o más. CONCLUSIONES. Las medidas generales de apoyo hemodinámico y la estrecha vigilancia de los pacientes pueden lograr salvaguardar sus vidas aunque no se disponga de un diagnóstico certero. La infección por Helicobacter pylori y su asociación a lesiones erosivas o ulcerosas de la mucosa gastroduodenal no ha sido totalmente asimilada en el pensamiento médico de los cirujanos. La función de la cirugía es cada vez menor en la terapéutica del sangramiento digestivo alto, a pesar de ser uno de los pilares fundamentales para enfrentarlo.INTRODUCTION.

Full Text Available Parvovirus is an infectious viral disease, highly contagious, affecting dogs causing acute enteritis. Dehydration is a minor problem and acute evolution, which is the main focus of treatment. The objective of this study was to evaluate two treatments volume replacement in dogs with confirmed diagnosis of parvovirus infection by antigen detection in stool by ELISA. A total of 15 dogs, mixed, male and female, aged from 3 to 6 months, these four they had died during treatment and 11 were included in the study. Patients were randomly divided into two groups: hydroxyethyl starch 130/0.4 (HES, n=6 and Group Ringer Lactate (RL, n=5, which received fluid resuscitation with hydroxyethyl starch 130/0.4 and Ringer’s solution lactate, respectively, based on calculations of fluid deficit. All animals received intravenously: cephalothin, metronidazole, ranitidine and metoclopramide. During hospitalization, every 12 hours were evaluated arterial blood gas, electrolyte dosing and clinical examination (heart rate, respiratory rate, rectal temperature, capillary refill time, vomiting, appetite, dehydration, weight gain, hematochezia, melena, hematemesis and presence abdominal pain and 24 hours each blood count was performed.

Full Text Available RACIONAL: O carcinoma basalóide escamoso ocorre com maior freqüência no trato aerodigestivo superior e raramente acomete o esôfago. OBJETIVO: Apresentar os aspectos clínico-patológicos e os atributos imunoistoquímicos de um paciente com carcinoma basalóide escamoso do esôfago. RELATO DO CASO: Dos 134 pacientes com câncer do esôfago atendidos no Hospital Universitário de Botucatu-Unesp, São Paulo, de 1990 a 1999, somente um paciente (0,74% apresentou carcinoma basalóide escamoso do esôfago. Tratava-se de paciente masculino, 41 anos, branco, lavrador com disfagia, regurgitação e emagrecimento há três meses. Referia tabagismo e etilismo há muitos anos. O esofagograma e o exame endoscópico revelaram lesão vegetante no terço distal do esôfago. A biópsia demonstrou neoplasia intraepitelial de alto grau associada a blocos de células basalóides que infiltravam o cório da mucosa, caracterizando o carcinoma basalóide escamoso. Os marcadores imunoistoquímicos foram positivos para o antígeno carcinoembriônico e para citoceratinas de alto peso molecular. A tomografia computadorizada revelou múltiplas metástases nos pulmões, fígado, e nódulos linfáticos regionais, documentando a fase avançada de evolução da doença. O tratamento consistiu apenas na realização de gastrostomia. O paciente apresentou queda acentuada do estado geral e evoluiu para óbito com quadro de melena quatro meses após o diagnóstico. CONCLUSÃO: O carcinoma basalóide escamoso é uma forma rara e agressiva de câncer do esôfago e o prognóstico depende do estadiamento da lesão e das condições clínicas do paciente no momento do diagnóstico.BACKGROUND: Basaloid squamous carcinoma is more frequently found in the upper aerodigestive tract, being rarely found in the esophagus.

Our purpose was to analyze risks versus benefits of nasogastric (NG) intubation for gastrointestinal (GI) bleeding performed soon after myocardial infarction (MI). While NG intubation and aspiration is relatively safe, clinically beneficial, and routinely performed in the general population for recent GI bleeding, its safety after MI is unstudied and unknown. In addition to the usual complications of NG tubes, patients status post-MI may be particularly susceptible to myocardial ischemia or cardiac arrhythmias from anxiety or discomfort during intubation. We studied NG intubation within 30 days of MI in 125 patients at two hospitals from 1986 through 2001. Indications for NG intubation included melena in 55 patients; fecal occult blood with an acute hematocrit decline, severe anemia, or sudden hypotension in 37; hematemesis in 18; bright red blood per rectum in 8; and dark red blood per rectum in 7. The intubation was performed on average 5.3 +/- 7.2 (SD) days after MI. NG aspiration revealed bright red blood in 38 patients, "coffee grounds"-appearing blood in 45, and clear (or bilious) fluid in 42. Among 114 of the patients undergoing esophagogastroduodenoscopy (EGD), EGD revealed the cause of bleeding in 79 (95%) of 83 patients with a grossly bloody NG aspirate versus 12 (39%) of 31 patients with a clear aspirate (P tube complications (epistaxis during intubation and gastric erosions from NG suctioning) were neither cardiac nor major (requiring blood transfusions). This study suggests that short-term NG intubation is relatively safe and may be beneficial and indicated for acute GI bleeding after recent MI. Aside from improving visualization at EGD, the potential benefits include providing a rational basis for the timing of endoscopy (urgent versus semielective), for prioritizing the order of endoscopy (EGD versus colonoscopy), and for avoiding or deferring endoscopy in low-yield situations (e.g., colonoscopy when the NG aspirate is bloody). These benefits may be

Objectives: To provide early data regarding clinical utility of dabigatran in Al-Ain, United Arab Emirates (UAE). Methods: This was an ethics approved retrospective cross sectional study. We retrieved a total of 76 patients who were using dabigatran from September to December 2014 in the Cardiology Clinic at Al-Ain Hospital, Al-Ain, UAE. The primary analysis was designed to test the frequency of bleeding events (rate) with dabigatran 75, 110, and 150 mg. Results: The mean age ± standard deviation of cohort was 67.9 ± 1.5 years (range; 29-98 years), composed of males (52.6%) with mean age of 66.3 ± 1.7 years, and females (47.4%) with mean age of 69.6 ± 1.1 years. The highest age group was those between 61-80 years (60.5%). Most comprised the age strata of ≤75 years (73.7%). The main indication for dabigatran use was atrial fibrillation. The rate of bleeding with dabigatran was 18/76 (23.7%), and melena was the leading cause of bleeding 8/76 (10.7%). The hospitalization rate was 67.1%, dabigatran withdrawal rate was 0.01%, and mortality rate was 6.5%. The cohort had exhibited incidences of minor bleeding with one fatal major bleeding, high co-morbidities, admission, and readmission, which was not directly linked to dabigatran. We did not identify any relation of death due to dabigatran. Conclusion: Dabigatran is a suitable alternative to warfarin obviating the need for repetitive international normalized ratio monitoring, however, it may need plasma drug monitoring. PMID:26593161

Proton pump inhibitor can effectively prevent recurrent peptic ulcers among atherosclerotic patients receiving clopidogrel monotherapy. However, the interaction between proton pump inhibitors and clopidogrel has raised concerns over the safety of combined use of the two medicines in clinical practice. The aims of this randomized-controlled, double-blind and double-dummy trial were to investigate the efficacy of histamine-2 receptor antagonist (H2RA) in the prevention of recurrent peptic ulcer in patients undergoing thienopyridine monotherapy. From January 2012 to 2016, long-termed thienopyridine users with a peptic ulcer history who did not have peptic ulcers at initial endoscopy were randomly assigned to receive either famotidine (40 mg, before bedtime) or placebo (before bedtime) for 6 months. Follow-up endoscopy was performed at the end of the 6th month and whenever dyspepsia, hematemesis, or melena occurred. The cumulative incidence of recurrent peptic ulcer during the 6-month period was 7.0% in famotidine group (n=114) and 11.4% in the placebo group (n=114). The two patient groups had comparable cumulative incidence of peptic ulcer (difference, 4.4%; 95% confidence interval (CI), -11.7 to 2.9%; P=0.239). Additionally, there was no difference in the cumulative incidence of ulcer bleeding (2.6% vs. 1.8%; difference, 0.8%; 95% CI, -0.6 to 2.4%, P=1.000) between famotidine and placebo groups. However, the former had a lower incidence of gastroduodenal erosion than the latter (21.1% vs. 36.8%; difference, 15.7%; 95% CI, -27.3 to -4.1%; P=0.013). Famotidine cannot decrease the incidence of peptic ulcer or ulcer bleeding in thienopyridine users with atherosclerotic disease and a history of peptic ulcer.

The purpose of the present study was to evaluate the number and proportion of various causes of upper gastrointestinal bleeding and actual numbers of non-NSAID, non-Helicobacter pylori (H.pylori) peptic ulcers seen in endoscopy of these patients. The number and the proportion of patients with non- H.pylori, non-NSAIDs peptic ulcer disease leading to upper gastrointestinal bleeding is believed to be increasing after eradication therapy for H.pylori. Medical records of patients referred to the emergency room of Taleghani hospital from 2010 with a clinical diagnosis of upper gastrointestinal bleeding (hematemesis, coffee ground vomiting and melena) were included in this study. Patients with hematochezia with evidence of a source of bleeding from upper gastrointestinal tract in endoscopy were also included in this study. In this study, peptic ulcer disease (all kinds of ulcers) was seen in 61 patients which were about 44.85% of abnormalities seen on endoscopy of patients. Among these 61 ulcers, 44 were duodenal ulcer, 22 gastric ulcer (5 patients had the both duodenal and gastric ulcers). Multiple biopsies were taken and be sent to laboratory for Rapid Urease Test and pathological examination. About 65.53% of patients had ulcers associated with H.pylori, 9.83% had peptic ulcer disease associated with NSAIDs and 11.47% of patients had ulcers associated with both H.pylori and consumption of NSAIDs. 13.11% of patients had non-NSAIDs non- H.pylori peptic ulcer disease. The results of this study supports the results of other studies that suggest the incidence of H.pylori infection related with duodenal ulcer is common, and that non-H pylori and non-NSAIDs duodenal ulcer is also common.

Multi-detector row computed tomography (MDCT) enables fast and thin acquisition of the abdominal anatomy. This allows multi-pass multi-planar studies that can be obtained during defined circulatory phases. When bolus timing is adequate, arterial phases with high contrast levels provide 'free lunch' CT angiographies eliminating the need for diagnostic angiographies in most cases. In addition to established clinical indications for abdominal CT such as preoperative MDCT of the liver or pancreas, MDCT of the abdomen is especially gaining ground in the work up for acute abdominal pain and abdominal trauma and is opening new indications for MDCT of the gastrointestinal tract. Indications for gastrointestinal MDCT include tumors, bleeding and ischemia of the small and large bowel as well as diverticulitis. The question of whether to use positive or negative contrast material for bowel distention for MDCT of the gastrointestinal tract is still a controversial issue. In selected cases, modifying the protocol to perform a 'CT enteroclysis' might improve sensitivity and specificity in depicting small bowel tumors or inflammatory changes such as in Crohn's disease. The most common gastrointestinal mesenchymal tumor is the gastrointestinal stromal tumor (GIST). MDCT may show hypervascular submucosal masses. Acute gastrointestinal (GI) bleeding is common with patients presenting with melena, hematemesis or hematochezia. In addition to the established initial work-up MDCT is beginning to establish itself for this indication. It may be especially helpful in the work up of obscure bleeding. Another relatively rare but important cause for acute abdominal pain is mesenteric ischemia. It may be caused by many conditions and may mimic various intestinal diseases. Bowel ischemia severity ranges from transient superficial changes of the intestinal mucosa to life-threatening transmural bowel wall necrosis. CT can demonstrate changes in ischemic bowel segments

Anal metastasis of colorectal cancer is very rare and is usually associated with a history of anal disease, including anal fistula, fissure, hemorrhoidectomy, and anastomotic injury. We report a case of rectal cancer with a synchronous anal metastasis consisting of adenocarcinoma of squamous cells without a history of anal disease. A 60-year-old woman had a chief complaint of melena. She had a 1.5-cm anal tumor on the perianal skin, and a Bollman type 2 rectal tumor on the Ra portion was found on colonoscopy. Biopsy of both tumors revealed a similar histology of well- to moderately differentiated adenocarcinoma. There was no sign of metastases in lymph nodes or other organs. For the purpose of diagnosis and treatment, transperineal local resection of the anal tumor was performed, and it was histologically identified as adenocarcinoma of squamous cells with no invasion to muscles, lymph ducts, or microvessels. The pathological margin was free. Then, to achieve radical cure, laparoscopic low anterior resection (LAR) with D3 lymphadenectomy was performed. The histological diagnosis of the anal tumor was adenocarcinoma of squamous cells without invasion to muscles, lymph ducts, or vessels. The surgical margin was completely free. Immunohistochemical analysis of both tumors revealed similar staining patterns, and the final diagnosis was rectal cancer with metastasis to the anal skin. The patient received no postoperative therapy, and no recurrences have been observed 12 months after surgery. We expect that our sphincter-preserving surgical strategy provided a good prognosis for the synchronous rectal cancer and anal metastasis. This is a rare report of a case with an anal metastasis of colorectal cancer on perianal squamous cells without a history of anal disease that was resected while preserving anal function.

Peptic ulcer disease is a multifactorial health problem, and its prevalence and risk factors have changed considerably within the past century. To determine the prevalence of peptic ulcer among the population of Arar city and to identify risk factors for peptic ulcer and to estimate their relative impact on ulcer incidence. A cross-sectional study was carried out on the population of Arar city, Northern Saudi Arabia from November 01, 2016 to April 30, 2017. Data were analyzed by SPSS version 16, using descriptive statistics, prevalence, and Chi-square test. Total prevalence of peptic ulcer among the studied respondents was thus: 21.9% had peptic ulcer; 16.2% gastric ulcer and 5.6% duodenal ulcer. In 19.7% of the cases, the pain was severe, 92.4% reported that pain was precipitated by certain food. In addition to heartburn, 78.8% reported loss of appetite, 71.2% indigestion, 66.7% regurgitation, 59.1% nausea and vomiting and 42.4% with chest pain. Regarding the risk factors, coffee drinking came in first place (81.8%) followed by physical stress in 77.3%, spicy food in 57.6%, prolonged use of Non-steroidal anti-inflammatory drugs (NSAIDs) in 33.3% and Helicobacter pylori (H. pylori) infection in 24.2%. A further 22.7% reported melena as a complication while only 10.6% reported hematemesis. This is the first population-based study in Arar, Northern Saudi Arabia reporting point prevalence of peptic ulcer disease. The rate of 16.2% for gastric ulcer and 5.6% for duodenal ulcers are substantially high. Coffee drinking, physical stress, spicy food, prolonged use of NSAID and H. pylori infection were the reported risk factors. Population-based endoscopic studies are recommended.
Full Text Available A 77-year-old man presented with repeated episodes of melena. He had a medical history of hypertension, atrial fibrillation and cardiogenic brain infarction and took medications, i.e. an antiplatelet agent. Laboratory data revealed iron deficiency anemia. Colonoscopy revealed a yellowish smooth submucosal tumor, 50 mm in diameter, on the Bauhin valve. The lesion was soft and compressible. The overlying mucosa was erosive. CT scan showed a uniform mass with very low density in the ascending colon, corresponding to the above-detected lesion. The clinical diagnosis of colonic lipoma was established. Using a 25 mm electrocautery snare (Olympus, Tokyo, Japan, we transected the upper portion of the mass to unroof the lesion. The mucosa layer was thick and hard. Fat tissue was observed extruding from the cut surface, consistent with the diagnostic hypothesis. After dissecting the overlying mucosa on the anal side by means of an IT knife (Olympus in order to completely extrude the mass, the fat tissue was further exposed. It took about 26 min to perform the whole procedure. There were no procedure-related complications. Macroscopically, the resected lesion was a yellow solid tumor, 1.6 × 1.5 × 0.7 cm in diameter. Histopathologic examination of the excised specimen confirmed the diagnosis of a lipoma. The clinical course was uneventful. A follow-up endoscopy 1 month later showed a scarred mucosa at the resection site. Similarly, a follow-up CT scan 2 months later revealed no evidence of residual lipoma. The unroofing technique is safe, easy and suitable for the treatment of large lipomas.

The effects of consumption of environmental contaminants contained in carp (Cyprinus carpio)from Saginaw Bay, Michigan on various hematological parameters and liver integrity of adult female mink (Mustela vison) were determined. Mink were fed diets that contained 0 (control), 10, 20, or 40% carp prior to and throughout the reproductive period (182 days). The diets contained 0.015, 0.72, 1.53, and 2.56 mg polychlorinated biphenyls (PCBs)/kg diet and 1.0, 19, 40, and 81 pg 2,3,7,8-tetrachlorodibenzo-p-dioxin equivalents (TEQs)/g diet, respectively. Mink fed the diets containing carp showed a general dose-dependent occurrence of clinical signs commonly associated with chlorinated hydrocarbon toxicity, including listlessness, nervousness when approached, anorexia, and melena. Erythrocyte counts were less in mink exposed to Saginaw Bay carp than in controls, while the number of white blood cells was greater than in controls. Significant differences (pdiets were significantly less than those of mink in the control and 10% carp groups. There were no significant differences in hemoglobin concentrations among the groups. Necropsies revealed enlarged yellowish livers in many of the carp-fed mink, especially those fed the 40% carp diet. Liver, spleen, and lung weights of carp-fed mink were significantly greater than those of control mink. Histopathologic examination of the livers revealed various degrees of congestion, hepatocellular fatty changes, and scattered portal lymphocytic infiltration which were most prevalent in mink fed the carp diets. These clinical signs, hematological effects, and histologic alterations are similar to those previously described for chlorinated hydrocarbon toxicoses in mink.
Full Text Available BackgroundIn contrast to the diverticulosis of the colon jejunal diverticulosis is a rare condition. The incidence is 0.06% up to 5% in large autopsy series. Complicated diverticulosis jejuni (CDJ often presents with unspecific symptoms. Therefore diagnosis is often a challenging diagnosis and due to the clinical rarity no generally valid recommendation of perioperative management exists. Patients and MethodsWe considered only patients that were operated in our centre between April 2007 and August 2014. Patients were identified by data bank search via International Statistical Classification of Diseases and Related Health Problems (ICD diagnosis code K57.10. Data was manually screened and patients with Meckel’s and duodenal diverticula were excluded from this study. Eleven consecutive patients with CDJ were finally included in this study. We analysed symptoms, diagnostic procedures, surgical treatment and postoperative morbidity and mortality. ResultsThe median age of our patients was 76 years (range 34 87. CDJ presented most frequently as intestinal bleeding or as diverticulitis. Clinical symptoms were unspecific abdominal pain, hematemesis or melena, ileus, nausea and emesis as well as patients with acute abdomen. Esophagogastroduodenoscopies confirmed CDJ in two of three patients. An abdominal CT-scan only helped to diagnose CDJ in two of ten patients. Eight (72.7% patients received an open segmental resection with primary anastomosis. In three (27.3% cases a reoperation was necessary. Overall morbidity rate was 45.5% and perioperative mortality was 9.1%. Conclusions Due to the acute character of the disease patients with CDJ are seriously ill. To diagnose patients with CDJ remains challenging as diagnostic investigations are usually not helpful in confirming diagnosis. Still, diagnosis of CDJ is most frequently confirmed intraoperatively.Keywords: complicated jejunal diverticulitis, perioperative management, acute abdomen, visceral surgery
Full Text Available Background: Critically ill children admitted to pediatric intensive care unit (PICU are at increased risk of gastrointestinal bleeding due to stress related mucosal injury. Reducing gastric acid by acid suppressant medication is the accepted prophylaxis treatment, but there is not any definitive guideline for using prophylaxis in PICU patients. The present study aimed to assess the effect of Proton Pump Inhibitor (PPI and H2 Blocker (H2B prophylaxis on gastrointestinal bleeding in admitted patients of PICU, Mashhad- Iran.Materials and Methods: In this study, 100 patients admitted in PICU divided into two equal groups on the first day of admission. They received ranitidine or pantoprazole as prophylaxis of stress ulcer. Those patients who had history of gastrointestinal bleeding or coagulation disorder were excluded. 100 PICU patients who had not received prophylaxis during last 6 months retrospectively evaluated as control of the study. Data were collected as demographic characteristics, admission reason, definitive diagnosis, receiving corticosteroid and mechanical ventilation in each patient. Gastrointestinal bleeding (hematemesis, coffee ground aspirate, and melena and clinically significant gastrointestinal bleeding were daily monitored. Data analyzed through descriptive statistical tests, Chi-square, logistic regression, t-test and using SPSS-16 software.Results: Among 204 patients (control group=105 and case group=99, incidence of gastrointestinal bleeding (GB was 13.2% in which 6.9% of cases presented with clinically significant gastrointestinal bleeding (CSGB. Loss of consciousness and respiratory distress were the main reason of admission. There was no significant differences between the incidence of (GB and (CSGB in experimental and control groups (P>0.05 as well as ranitidine and pantoprazole prophylaxis (P>0.05. Significant risk factors of (GB were mechanical ventilation and loss of consciousness and corticosteroid therapy

This article is aimed to retrospect the clinicopathological data of 2 cases of gastric MANENCs. MANEC is a rare biphasic tumor type that is coexistence of dual neuroendocrine and adenocarcinoma differentiation with each composing exceeding 30% volume. Gastric MANEC have just been reported anecdotally in the literature due to their rarity and heterogeneity. According to our study, these neoplasms have 3 different metastasis patterns: only adenocarcinomatous or neuroendocrine carcinoma and both of the 2 components. We first focus on the correlation of metastasis characteristics with prognosis in gastric MANEC, which may be potential implications for the choice of chemotherapy. The 2 cases of patient shared several symptoms: epigastric discomfort, weight loss, hematemesis, or melena. The 2 patients were diagnosis as MANEC based on the identification of histopathological analysis. In case 1, the poor differentiated adenocarcinoma accounted for 30%, the neuroendocrine part account for 70% and both of the 2 components metastasized to the lymph nodes, whereas in case 2, poorly differentiated adenocarcinoma accounted for 70%, the neuroendocrine part for 30% and only the glandular component invaded regional lymph nodes. The first patient underwent laparoscopic radical gastrectomy and underwent adjuvant chemotherapy, combination of cisplatin, and etoposide successfully. The second patient received radical gastronomy, and did not receive any chemotherapy due to general weakness. The first patient is alive with no evidence of recurrence, and the second patient died 6 months after the operation. The assessment of metastatic sites should be a routine pathological practice, which is crucial for clinical decision-making and the selection of management. Copyright © 2017 The Authors.

BACKGROUND Percutaneous catheter radiofrequency ablation (RFA) and cryoablation of the left atrium and pulmonary vein ostia have become successful therapeutic modalities in the management of atrial fibrillation. Atrio-esophageal fistula is a rare complication. Awareness of complication risk is imperative because without prompt diagnosis and urgent surgical intervention, the outcome is often fatal. We present 3 cases of atrio-esophageal fistula following percutaneous catheter radiofrequency ablation (RFA). CASE REPORT Case 1: A 72-year old white male presented 27 days after percutaneous RFA for atrial fibrillation with fever, altered mental status, and melena. Esophagogastroduodenoscopy (EGD) revealed a 1-cm defect in the mid-esophagus. Upon thoracotomy, severe hemorrhage ensued from a concomitant injury to the left atrium. Multiple attempts to repair the left atrial perforation were unsuccessful and the patient died. Case 2: A 71-year old white male presented 29 days after percutaneous RFA for atrial fibrillation with fever and tonic-clonic seizure. Recognition of possible atrio-esophageal fistula was considered and confirmed on thoracotomy. Surgical fixation of the left atria and esophagus were performed. The patient survived and was discharged to a skilled care facility. Case 3: A 75-year old white male presented 24 days after percutaneous RFA for atrial fibrillation with chest pain. An echocardiogram revealed a large pericardial effusion and pericardiocentesis was performed. Despite aggressive measures, the patient died. The autopsy demonstrated a communicating esophageal fistula with the right pulmonary vein. CONCLUSIONS Clinicians tending to patients who have recently undergone atrial ablation need to be aware of atrio-esophageal fistula as a rare but highly fatal complication.
Full Text Available Introduction: Pseudoaneurysm is a serious complication after pancreatic surgery, which mainly depends on the presence of a preceding pancreatic fistula. Postpancreatectomy hemorrhage following total pancreatectomy is a rare complication due to the absence of a pancreatic fistula. Here we report an unusual case of massive gastrointestinal bleeding due to right hepatic artery (RHA pseudoaneurysm following total remnant pancreatectomy. Presentation of case: A 75-year-old man was diagnosed with intraductal papillary mucinous carcinoma recurrence following distal pancreatectomy and underwent total remnant pancreatectomy. After discharge, he was readmitted to our hospital with melena because of the diagnosis of gastrointestinal bleeding. Gastrointestinal endoscopy was performed to detect the origin of bleeding, but an obvious bleeding point could not be detected. Abdominal computed tomography demonstrated an expansive growth, which indicated RHA pseudoaneurysm. Emergency angiography revealed gastrointestinal bleeding into the jejunum from the ruptured RHA pseudoaneurysm. Transcatheter arterial embolization was performed; subsequently, bleeding was successfully stopped for a short duration. Because of improvements in his general condition, the patient was discharged. Discussion: To date, very few cases have described postpancreatectomy hemorrhage following total remnant pancreatectomy. We suspect that the aneurysm ruptured into the jejunum, possibly because of the scarring and inflammation associated with his two complex surgeries. Conclusion: Pseudoaneurysm should be considered when the fragility of blood vessels is suspected, despite no history of anastomotic leak and intra-abdominal abscess. Our case also highlighted that detecting gastrointestinal bleeding is necessary to recognize sentinel bleeding if the origin of bleeding is undetectable.

Full Text Available We present the case of a 68-year-old female patient who was diagnosed with cancer of the descending colon in July 1994 and underwent partial resection of the colon (type 2, moderately to well differentiated adenocarcinoma, se, ly1, v1, n(–. In April 1996, she was admitted to a nearby hospital for symptoms of ileus, which improved at the hospital. However, she was referred to our hospital for melena. In blood test, Hb was 8.7 g/dl, showing anemia, and carcinoembryonic antigen level was elevated to 50.7 ng/ml. Abdominal CT and small bowel series showed only mild expansion of the small bowel, suggesting no obvious occlusion. Abdominal surgery was performed in May 1995 for repeated development of ileus symptoms and suspicion of bleeding from the small bowel. Since the findings of the abdominal surgery showed a circular tumor in the lower ileum, partial resection of the small bowel was performed. Histopathological examination showed type 3, moderately to well differentiated adnocarcinoma, se, ly2, v0, n = 1/13. The principal tumor was located within the subserosa and grew up exclusively through the muscularis propria and the submucosa, into the mucous layer. The mucosa remained slightly on the surface layer. Based on these findings, the patient was diagnosed with metastasis of descending colon cancer to the small bowel. Her prognosis was good, and neither metastasis nor redevelopment of the cancer have been confirmed to date, 11 years and 7 months since the surgery.

Notoedric mange was responsible for a population decline of bobcats (Lynx rufus) in 2 Southern California counties from 2002–2006 and is now reported to affect bobcats in Northern and Southern California. With this study we document clinical laboratory and necropsy findings for bobcats with mange. Bobcats in this study included free-ranging bobcats with mange (n = 34), a control group of free-ranging bobcats without mange (n = 11), and a captive control group of bobcats without mange (n = 19). We used 2 control groups to evaluate potential anomalies due to capture stress or diet. Free-ranging healthy and mange-infected bobcats were trapped or salvaged. Animals were tested by serum biochemistry, complete blood count, urine protein and creatinine, body weight, necropsy, and assessment for anticoagulant rodenticide residues in liver tissue. Bobcats with severe mange were emaciated, dehydrated, and anemic with low serum creatinine, hyperphosphatemia, hypoglycemia, hypernatremia, and hyperchloremia, and sometimes septicemic when compared to control groups. Liver enzymes and leukocyte counts were elevated in free-ranging, recently captured bobcats whether or not they were infested with mange, suggesting capture stress. Bobcats with mange had lower levels of serum cholesterol, albumin, globulin, and total protein due to protein loss likely secondary to severe dermatopathy. Renal insufficiency was unlikely in most cases, as urine protein:creatinine ratios were within normal limits. A primary gastrointestinal loss of protein or blood was possible in a few cases, as evidenced by elevated blood urea nitrogen, anemia, intestinal parasitism, colitis, gastric hemorrhage, and melena. The prevalence of exposure to anticoagulant rodenticides was 100% (n = 15) in bobcats with mange. These findings paint a picture of debilitating, multisystemic disease with infectious and toxic contributing factors that can progress to death in individuals and potential decline in populations.
Full Text Available Abstract Introduction Hemobilia is a rare cause of upper gastrointestinal bleeding. More than 50% of hemobilia cases are related to iatrogenic trauma from hepatobiliary procedures, and needle biopsy of the liver represents the most common cause. A minority of hemobilia cases are due to hepatobiliary disorders such as cholangitis, hepatobiliary cancers, choledocholithiasis, and vascular abnormalities in the liver. The classic presentation of hemobilia is the triad of right upper quadrant (biliary pain, obstructive jaundice, and upper gastrointestinal bleeding. We report a rare case of hemobilia caused by a spontaneous hepatic cyst rupture, where our patient presented without the classical symptoms, in the absence of therapeutic or pathological coagulopathy, and in the absence of spontaneous or iatrogenic trauma. Case presentation A 91-year-old African-American woman was referred to our out-patient gastroenterology clinic for evaluation of mild epigastric pain and intermittent melena. An abdominal computed tomography scan was remarkable for multiple hepatic cysts. Esophagogastroduodenoscopy revealed multiple blood clots at the ampulla of Vater. Endoscopic retrograde cholangiopancreatography showed a single 18 mm-sized filling defect in the common hepatic duct wall at the junction of the right and left hepatic duct, adjacent to one of the hepatic cysts. The ruptured hepatic cyst communicated to the bile ducts and was the cause of hemobilia with an atypical clinical presentation. Conclusion Hemobilia is an infrequent cause of upper gastrointestinal bleeding and rarely occurs due to hepatic cyst rupture. To the best of our knowledge, this is only the second case report in the literature that describes hemobilia due to hepatic cyst rupture. However, it is the first case in the literature of hemobilia due to hepatic cyst rupture in the absence of iatrogenic or spontaneous trauma, and in the absence of a spontaneous or pathological coagulopathy.
Full Text Available The study was conducted on 20 adult healthy medium-sized mongrel dogs. Injection of dexamethasone @ 1 mg/kg, IV, b.i.d., was administered to create gastric ulcerations and erosions. Thereafter all the animals were randomly divided into 5 equal treatment groups. Animals of groups I, II, III, IV, and V were treated with oral administration of lansoprazole @ 1.5 mg/kg, sucralfate @ 1 g/animal, misoprostol @ 10 µg/kg, famotidine @ 1 mg/kg, and Seabuckthorn seed oil @ 5 mL/animal, twice a day, respectively. Gastroendoscopically, complete healing of GUE lesions was earliest in Seabuckthorn- (SBT- oil-treated group (7.5±0.87 followed by famotidine (8.25±1.44, lansoprazole (9.00±1.23, misoprostol (10.50±1.50, and sucralfate (13.50±0.87, respectively. A marked improvement in appetite was observed in all animals. Melena was continued till day 3 in SBT group, day 6 in lansoprazole- and famotidine-treated animals, and day 9 in sucralfate and misoprostol group animals. Fecal occult blood test was positive in all animals till there was endoscopic evidence of gastric bleeding. Hematological parameters improved markedly towards the end of the study. Serum biochemical parameters remained within normal physiological limits throughout the study. It is concluded that Seabuckthorn oil was the best therapeutic agent for dexamethasone-induced GUE in dogs followed by famotidine, lansoprazole, misoprostol, and sucralfate.

The HD97950 cluster and its immediate surroundings in the giant HII region NGC3603 were observed with the Hubble Space Telescope (HST). The ultraviolet (UV) data were taken with the High Resolution Channel (HRC) of the Advanced Camera for Surveys (ACS) in 2005 (GO 10602, PI: Jesus Maiz Apellaniz) through the F220W, F250W, F330W, and F435W filters. The HRC is characterized by a spatial resolution of 0.03"/pixel and a field of view of 29''*25''. The optical observations were carried out with the Wide Field and Planetary Camera 2 (WFPC2) in two epochs: 1997 (GO 6763, PI: Laurent Drissen) and 2007 (GO 11193, PI: Wolfgang Brandner) through the F555W, F675W, and F814W filters. The Planetary Camera (PC) chip was centered on the cluster (0.045"/pixel, 40''*40'') for both programs. Pang et al. 2013 (cat. J/ApJ/764/73) reduced the two-epoch WFPC2 data and identified more than 400 member stars on the PC chip via relative proper motions. Of these member stars, 142 are in common between the HRC and PC images and thus have UV and optical photometry available (see Table1). Among the HD97950 cluster member stars determined from relative proper motions (Pang et al. 2013, cat. J/ApJ/764/73, Table2), there are five main-sequence (MS) stars located in the cluster with projected distances of r<0.7pc from the center, for which there are also spectral types available from Table3 of Melena et al. (2008AJ....135..878M). The photometry of these five MS stars is presented in Table2. The individual color excesses and extinctions of the member main sequence stars are listed in Table3. (3 data files).

Full Text Available Aim: The aim of this study was to determine the relevant tools in the diagnosis of liver cirrhosis in dogs. Material and Methods: A total of 140 dogs presented at Veterinary Teaching Hospital, Guru Angad Dev Veterinary and Animal Sciences University, Ludhiana, showing clinical signs of hepatic insufficiency were subjected to clinico-hemato biochemical, urological, ultrasonographic (USG, and USG guided fine-needle biopsy examinations by standard methods. On the basis of these results, 6 dogs out of 140 dogs were found to be suffering from liver cirrhosis. Six clinically healthy dogs constituted the control group. Results: The dogs suffering from liver cirrhosis manifested inappetence, halitosis, abdominal distension, weight loss, melena, icterus, anemia, and neutrophilic leukocytosis with the left shift. Levels of hemoglobin, lymphocytes, packed cell volume, mean corpuscular volume, mean corpuscular Hb (MCH, and platelet count were significantly lower in liver cirrhosis group than control group while total leukocyte count, neutrophils, and MCH concentration were significantly higher. Glucose, total protein, albumin, A/G ratio, and fibrinogen were significantly lower, and creatinine, alanine aminotransferase, aspartate aminotransferase, alkaline phosphatase, prothrombin time, and APTT were significantly higher than the control values. Ultrasound revealed diffuse increase in echogenicity with rounded and irregular liver margins. Cytological examination of the ascitic fluid and fine-needle aspiration biopsy of liver was not fruitful in the diagnosis of liver cirrhosis. Conclusions: Liver cirrhosis causes clinical and hemo-biochemical alterations, which require special consideration when treating diseased animals. USG, diffuse increase in echogenicity of liver, rounding and irregularity of liver margins and microhepatica were the consistent findings. It is suggested that USG along with hemo-biochemical alterations may be used as a diagnostic tool for

Bobcats in this study included free-ranging bobcats with mange (n = 34), a control group of free-ranging bobcats without mange (n = 11), and a captive control group of bobcats without mange (n = 19). We used 2 control groups to evaluate potential anomalies due to capture stress or diet. Free-ranging healthy and mange-infected bobcats were trapped or salvaged. Animals were tested by serum biochemistry, complete blood count, urine protein and creatinine, body weight, necropsy, and assessment for anticoagulant rodenticide residues in liver tissue. Bobcats with severe mange were emaciated, dehydrated, and anemic with low serum creatinine, hyperphosphatemia, hypoglycemia, hypernatremia, and hyperchloremia, and sometimes septicemic when compared to control groups. Liver enzymes and leukocyte counts were elevated in free-ranging, recently captured bobcats whether or not they were infested with mange, suggesting capture stress. Bobcats with mange had lower levels of serum cholesterol, albumin, globulin, and total protein due to protein loss likely secondary to severe dermatopathy. Renal insufficiency was unlikely in most cases, as urine protein:creatinine ratios were within normal limits. A primary gastrointestinal loss of protein or blood was possible in a few cases, as evidenced by elevated blood urea nitrogen, anemia, intestinal parasitism, colitis, gastric hemorrhage, and melena. The prevalence of exposure to anticoagulant rodenticides was 100% (n = 15) in bobcats with mange. These findings paint a picture of debilitating, multisystemic disease with infectious and toxic contributing factors that can progress to death in individuals and potential decline in populations.
Pathogenesis of highly virulent African swine fever virus in domestic pigs exposed via intraoropharyngeal, intranasopharyngeal, and intramuscular inoculation, and by direct contact with infected pigs.
Howey, Erin B; O'Donnell, Vivian; de Carvalho Ferreira, Helena C; Borca, Manuel V; Arzt, Jonathan
To investigate the pathogenesis of African swine fever virus (ASFV), domestic pigs (n=18) were challenged with a range (10(2)-10(6) 50% hemadsorbing doses (HAD50)) of the highly virulent ASFV-Malawi strain by inoculation via the intraoropharyngeal (IOP), intranasopharyngeal (INP), or intramuscular (IM) routes. A subsequent contact challenge experiment was performed in which six IOP-inoculated donor pigs were allowed to have direct contact (DC) with six naïve pigs for exposure times that varied from 24 to 72 h. All challenge routes resulted in clinical progression and postmortem lesions similar to those previously described in experimental and natural infection. The onset of clinical signs occurred between 1 and 7 days post inoculation (dpi) and included pyrexia with variable progression to obtundation, hematochezia, melena, moribundity and death with a duration of 4-11 days. Viremia was first detected between 4 and 5 dpi in all inoculation groups whereas ASFV shedding from the nasal cavity and tonsil was first detected at 3-9 dpi. IM and DC were the most consistent modes of infection, with 12/12 (100%) of pigs challenged by these routes becoming infected. Several clinical and virological parameters were significantly different between IM and DC groups indicating dissimilarity between these modes of infection. Amongst the simulated natural routes, INP inoculation resulted in the most consistent progression of disease across the widest range of doses whilst preserving simulation of natural exposure and therefore may provide a superior system for pathogenesis and vaccine efficacy investigation.

The Helicobacter pylori (Hp) is found in patients with gastritis and peptic ulcer approximately in up to 80 percent. The eradication rates of 80 to 90 percent are achievable with some regimens. Evaluate two regimens for H pylori eradication in gastritis and peptic ulcer. Patients more than 20 years old with gastritis, gastric and duodenal ulcer disease and H pylori positive entered the study. We investigated prior history of peptic ulcer and hemorrhage, NSAID's use, smoking, alcoholism and epigastric pain. Endoscopy was performed before and at the end of the 8-12 weeks treatment, biopsies were taken from the antrum for Hp histological detection. Patients were randomly assigned to receive bismuth-metronidazole-tetracycline-ranitidine or bismuth-metronidazole-amoxicillin-ranitidine during two weeks. chi square and multivariate analysis. One hundred and eighteen patients were included in this study, 52% male and 48% female with mean age of 47 +/- 16 years. History of peptic ulcer and bleeding was present in 79% and 62% respectively. NSAID's, and tobacco use among all patients was 49%, and 30%. Epigastric pain, melena and hematemesis was present in 90%, 47% and 24% respectively. H pylori eradication treatment was successful in 70% in both regimens (pNS). Was no related to age, tobacco and alcohol for Hp eradication (pNS), and NSAID's use was inversely related to Hp eradication (p peptic ulcer was seen in 23%. Eradication treatment was successful in 70% (p NS). Peptic ulcer refractory in 23% of patients and NSAID's use was inversely related to Hp eradication (p 0.05).

Schwannomas are benign tumors derived from Schwann cells and their typical site of origin is the subcutaneous tissue of the extremities. Gastrointestinal localization of Schwannomas is extremely rare and the stomach is the prevalent site. Gastric schwannomas primarily occur in the gastric submucosa and are usually asymptomatic.We present a rare case of a solitary gastric schwannoma in a 51-year old male, which initially manifested with hematemesis by acute upper gastrointestinal (GI) bleeding. The upper GI-Endoscopy revealed a gastric submucosal tumor, 7 cm in size, located in the proximal corpus and fundus. In the endoscopical Ultrasound (EUS-Examination), the lesion appeared to arise from the fourth proper muscle layer (Muscularis propria). The fourth layer origin and the isoechogenicity, as compared to the normal muscle layer, are endoscopic ultrasonographic characteristics of gastric schwannomas and help in distinguishing them from gastrointestinal tumors (GIST). Because of the unclear histological identity, the patient underwent a "rendezvous" endoscopic-laparoscopic surgical resection of the tumor in toto. The histomorphological features of the lesion and the strong expression of S100 in combination with absence of DOG1 expression indicated the diagnosis of gastric schwannoma. There was no evidence of malignancy. The postoperative course was uncomplicated.This is a very rare manifestation of gastric schwannoma, representing a rare differenzial diagnosis in a case of acute upper GI-Bleeding. Only 14 % of gastric schwanommas are presented with gastrointestinal bleeding, including mainly melena rather than hematemesis. This case is considered to be worthy of presentation owing to the rare and unusual cause of upper GI bleeding implied in it. © Georg Thieme Verlag KG Stuttgart · New York.
Full Text Available Abstract Background Although patients with systemic lupus erythematosus (SLE may experience various gastrointestinal disorders, SLE and Crohn’s disease (CD rarely coexist. The diseases may have gastrointestinal (GI manifestations, laboratory results, and radiographic findings that appear similar and consequently differentiating between GI involvement in CD and in SLE may be difficult. We present the case of a patient with SLE and CD who developed continuous GI bleeding and diarrhea that was initially treated as SLE-related colitis to little effect. Case presentation A 55-year-old Japanese woman with systemic lupus erythematosus (SLE developed continuous gastrointestinal bleeding and diarrhea since the patient was aged 30 years that was initially treated as SLE-related colitis. Although a longitudinal ulcer and aphthous ulcers in the colon were observed every examination, biopsy showed only mild inflammation and revealed neither granuloma nor crypt abscess. The patient underwent surgery for anal fistulas twice at 50 and 54 years of age and her symptoms were atypical of lupus enteritis. Colonoscopy was performed again when the patient was 55 years of age because we suspected she had some type of inflammatory bowel disease (IBD. Cobblestone-like inflammatory polyps and many longitudinal ulcers were detected between the descending colon and the cecum. Macroscopic examination strongly suggested CD. Histopathological examination revealed non-caseating granuloma and no evidence of vasculitis, consistent with CD. Introduction of infliximab dramatically relieved the patient’s melena and abdominal symptoms. Conclusion Diagnostic criteria for CD and SLE overlap, making them difficult to diagnose correctly. It is important to consider CD for patients who have SLE with gastrointestinal manifestations. The pathology of lupus enteritis should be clarified through the accumulation of cases of SLE combined with CD.

In this review of studies on the hemorrhagic fevers of Southern Africa carried out in the South African Institute for Medical Research, attention has been called to occurrence of meningococcal septicemia in recruits to the mining industry and South African Army, to cases of staphylococcal and streptococcal septicemia with hemorrhagic manifestations, and to the occurrence of plague which, in its septicemic form, may cause a hemorrhagic state. "Onyalai," a bleeding disease in tropical Africa, often fatal, was related to profound thrombocytopenia possibly following administration of toxic witch doctor medicine. Spirochetal diseases, and rickettsial diseases in their severe forms, are often manifested with hemorrhagic complications. Of enterovirus infections, Coxsackie B viruses occasionally caused severe hepatitis associated with bleeding, especially in newborn babies. Cases of hemorrhagic fever presenting in February-March, 1975 are described. The first outbreak was due to Marburg virus disease and the second, which included seven fatal cases, was caused by Rift Valley fever virus. In recent cases of hemorrhagic fever a variety of infective organisms have been incriminated including bacterial infections, rickettsial diseases, and virus diseases, including Herpesvirus hominis; in one patient, the hemorrhagic state was related to rubella. A boy who died in a hemorrhagic state was found to have Congo fever; another patient who died of severe bleeding from the lungs was infected with Leptospira canicola, and two patients who developed a hemorrhagic state after a safari trip in Northern Botswana were infected with Trypanosoma rhodesiense. An illness manifested by high fever and melena developed in a young man after a visit to Zimbabwe; the patient was found to have both malaria and Marburg virus disease.

Gastrointestinal and liver disorders are often observed in high performance athletes, especially those training for the increasingly popular endurance sports including the marathon and the triathlon. The disorders often start with stress before competition or training, followed by dehydration during the event. Insufficient training is an aggravating factor as are certain environmental factors including hot climate, irregular terrain and high altitude. Athletes may also consume non-steroid anti-inflammatory drugs, for example after a minor bone lesion or joint sprain, in an attempt to maintain their highest level of performance. Gastric signs include epigastric pain known to be caused by ischaemic gastritis resulting from decreased splanchnic flow and increased vasoconstriction in the gastric mucosa. Gastrooesophageal reflux results from modifications in sphincter tone and gastric emptying. Drinking hyperosmolar liquids also plays a role. Abdominal pain, diarrhoea, melena and uncommonly ischaemic colitis are the main signs of colic disorders. Mesenteric ischaemia may occur due to lowered splanchnic blood supply (by as much as 80% in some cases). Mechanical trauma is another mechanism; in marathon runners the "caecal slap syndrome" is a repeated microtrauma of the caecum against a hypertrophied muscular wall. Waterborne infectious agents may also lead to colic lesions. Exertion heat stroke is an emergency situation which can cause multiple organ damage and usually occurs after long intense exercise, often, but not always in a hot environment. Uncompensated thermogenesis and excessive loss of water by perspiration leads to central hyperthermia and ischaemic hepatic necrosis. Fatal liver failure has been observed. More or less severe symptoms of gastrointestinal or hepatic disorders are observed in 30% of high performance athletes and the incidence may reach 40% in those who have trained insufficiently. Such disorders lead to reduced performance in 10% of these
Full Text Available Objective: To explore the value of color Doppler ultrasound in the diagnosis of portal hypertension liver cirrhosis merged with esophageal variceal bleeding. Methods: The clinical materials of 30 patients with portal hypertension liver cirrhosis merged with esophageal varices who were admitted in our hospital from August, 2014 to August, 2015 were retrospectively analyzed. According to whether there was a history of hematemesis and melena or not before and 3 months after ultrasound examination, and whether was esophageal variceal bleeding or not confirming by the electronic gastroscopy, the patients were divided into the bleeding group (17 cases and non-bleeding group (13 cases. The color Doppler ultrasonic diagnosis apparatus was used to detect the inner diameter and blood flow rate of splenic vein, portal vein, and left gastric vein. The blood flow volume of splenic vein, portal vein, and left gastric vein was calculated. Results: The inner diameter and blood flow volume of splenic vein in the bleeding group were significantly higher than those in the non-bleeding group, but the blood flow rate was significantly lower than that in the non-bleeding group (P0.05. The inner diameter of left gastric vein in the bleeding group was significantly higher than that in the non-bleeding group, but the blood flow rate was significantly lower that that in the non-bleeding group (P0.05. Conclusions: Color Doppler ultrasound can detect the inner diameter of splenic vein, portal vein, and left gastric vein, and the related hemodynamic indicators, particularly, the inner diameter, blood flow rate, and blood flow volume of splenic vein are effective in predicting the risk of esophageal variceal bleeding.

Oxygen absorbers are commonly used in packages of dried or dehydrated foods (e.g., beef jerky, dried fruit) to prolong shelf life and protect food from discoloration and decomposition. They usually contain reduced iron as the active ingredient although this is rarely stated on the external packaging. Although reduced iron typically has minimal oral bioavailability, such products are potential sources of iron poisoning in companion animals and children. We present a case of canine ingestion of an oxygen absorber from a bag of dog treats that resulted in iron intoxication necessitating chelation therapy. A 7-month-old female Jack Russell terrier presented for evaluation of vomiting and melena 8-12 h after ingesting 1-2 oxygen absorber sachets from a package of dog treats. Serum iron concentration and ALT were elevated. The dog was treated with deferoxamine and supportive care. Clinical signs resolved 14 h following treatment, but the ALT remained elevated at the 3-month recheck. The ingestion of reduced iron in humans has been reported to cause mild elevation of serum iron concentration with minimal clinical effects. To our knowledge, no cases of iron intoxication following the ingestion of oxygen absorbers have been reported. The lack of ingredient information on the packaging prompted analysis of contents of oxygen absorber sachets. Results indicate the contents contained 50-70% total iron. This case demonstrates that iron intoxication can occur following the ingestion of such products. Human and veterinary medical personnel need to be aware of this effect and monitor serum iron concentrations as chelation may be necessary.

To describe the clinical characteristics, epidemiology, predictors of fatal outcome (PFO), and management effects of Crimean-Congo haemorrhagic fever (CCHF) patients during an outbreak in Northern Balochistan. Patients presenting with a fever of less than 2 weeks duration and bleeding manifestations were included. Clinical history was recorded and patients were placed on oral ribavirin, and hematological support. Diagnosis was established by PCR for CCHF or detection of CCHF specific IgM and IgG. Eighty-four patients were received, 34 (40.5%) were suspected of suffering from classical CCHF. All 34 (100%) patients presented with a history of fever and bleeding (epistaxis, gum bleeding, melena or haematuria). Mean platelet count was 30 x 109/L and mean ALT (alanine transferase) was 288 U/L. Among fatal cases, the mean platelet count was 18.4 x 10 9/L and ALT was 781 units/L. PCR for CCHF viral RNA performed on 10 patients was positive in 3 (30%) patients. CCHF specific IgM and IgG was positive in 17.6% (6/34). Four patients were brought in moribund condition and expired before treatment could be started, 4 patients expired during treatment and 76.5% (26/34) were cured. The overall mortality was 23.5% (8/34). Main predictors of fatal outcome were ALT z 150 units/L, activated partial thromboplastin time(aPT) z 60 seconds, prothrombin time (PT) z 34 seconds, aspartate transferase (AST) z 200 units/L, platelets o 20 x 109/L, and fibrinogen o 110 mg/dL. In this series of CCHF occurring in Northern parts of Balochistan, gastrointestinal tract bleeding was the worst prognostic factor associated with fatal outcome. Providing education to healthcare workers and at risk populations, hematological support, antiviral drugs, and barrier nursing may help reduce mortality. (author)

The present study intends to validate the Rockall Score in patients with upper gastrointestinal bleeding (UGB) in our current medical setting and to find the value that best discriminates between patients with high or low risk of mortality, rebleeding and the need of more than two units of packed red blood cells (PRBC). A descriptive prospective study was made from patients who arrived to Cayetano Heredia Hospital's emergency department between February 2007 and January 2008 due to UGB symptoms (hematemesis, coffe ground remit melena or hematoquezia). The Rockall score was used to determine severity of UGB and to stratify patients with higher risk of mortality or rebleeding. All patients were interviewed and any additional information was gathered from medical history records and emergency and hospitalization endoscopic procedure reports. During the study all patients were evaluated for rebleeding, the number of units of PRBCs needed and mortality rate. 163 patients were included in our study, 107 (65.64%) were male and 56 (34.36%) female, 8 were excluded due to lack of an endoscopic procedure. The remaining 155 patients were studied to evaluate the discriminative ability of the scoring system, and to determine which value best distinguishes high and low severity patients using Receiver Operating Characteristic curve (ROC) and calculated area under the curve. The data analysis showed patients with a Rockall Score e 5 had an increased mortality rate compared to lower score with an area under the curve of 0.807, meaning an accurate relationship between mortality and a score e 5. For rebleeding and the need of two packed red blood cells for transfusion, the area under the curve were 0.65 and 0.64 respectively showing a low predictive value. The Rockall scoring system is useful to identify patients with high mortality risk, but not to predict rebleeding or the need for blood transfusion in our hospital.

Aims: Show the utility of this technique in the detection of Lower Digestive Hemorrhage (LDH) in elderly patients and propose a study algorithm. Materials and Methods: We study 39 patients (20 women and 19 men), between 61 and 92 years (media 76,3 years), in the last three years, that we strongly presume they have a LDH. In all of them we lay aside the upper digestive hemorrhage with endoscopies. In all the cases we perform a video-colonoscopy after the scintigraphy adopting in every case if its necessary surgery, medication or expectant conduct. We use the modified red cells mark 'in vivo' method (mark efficiency of 82%). We obtain anterior images of the abdomen with a planar Gamma Camera. Sequential images of 1 minute duration in the first hour post-injection I.V. of 740 MBq of Tc99- pertechnetate -Stannous Chloride and hen static images with 400 K counts at 60, 120, 180 and 240 minutes and one image at 24 hours were acquired, in two cases repeat the study. We don't do selective angiographies because we consider this a high risk and low cost / benefit study in elderly patients (high association with cardiopathy). Result: Patient with final diagnosis for VCC or Surgery: Angio dysplasia (38%), Diverticulosis (20%), Ischemic colitis (11%), Ulcerous colitis (8%) and Colon adenocarcinoma (2%). In some cases were two pathologies involved (13%). The scintigraphies were positive in 92% and negative in 8% of the cases. All the positives were in massive or recidivated bleeding and the negatives in intermittent low volume bleedings or patients with discreet melena or hidden blood in feces. The diagnostic efficiency of 92% was compare with non-invasive methods (video-colonoscopy 81% and selective angiography) and we comment the possible causes of false negatives. Conclusion: We propose a study algorithm for intermittent and low intensity LDH cases and another for higher magnitude LDH
Full Text Available Abstract Introduction Acquired factor VIII deficiency is a rare entity that can lead to severe and life-threatening bleeding. We describe a case of severe bleeding from the tongue secondary to acquired hemophilia and discuss treatment options, including aminocaproic acid and recombinant factor VIII, which have not been widely reported in the literature for the management of such patients. Case presentation A 94-year-old Caucasian man presented to our institution with diffuse bruising and extensive bleeding from the tongue secondary to mechanical trauma. He had no prior history of bleeding and his medical history was unremarkable except for dementia and hypertension. Coagulation studies revealed a prolonged activated partial thromboplastin time and a mixing study was consistent with the presence of an inhibitor. Quantitative assays revealed a reduced level of factor VIII activity (1% and the presence of a factor VIII inhibitor, measured at seven Bethesda units, in the serum. Oral prednisone therapy (60mg/day was given. He also received intravenous aminocaproic acid and human concentrate of factor VIII (Humate-P and topical anti-thrombolytic agents (100 units of topical thrombin cream. His hospital course was prolonged because of persistent bleeding and the development of profuse melena. He required eight units of packed red blood cells for transfusion. Hospitalization was also complicated by bradycardia of unclear etiology, which started after infusion of aminocaproic acid. His activated partial thromboplastin time gradually normalized. He was discharged to a rehabilitation facility three weeks later with improving symptoms, stable hematocrit and resolving bruises. Conclusions Clinicians should suspect a diagnosis of acquired hemophilia in older patients with unexplained persistent and profound bleeding from uncommon soft tissues, including the tongue. Use of factor VIII (Humate-P and aminocaproic acid can be useful in this coagulopathy but

The indications for platelet transfusion in dengue fever are clearly defined in World Health Organization (WHO) guidelines (2011) for dengue fever, but physicians face practical difficulty in its implementation in an epidemic setting. On one hand there is an intense social pressure created by the panic-struck parents to transfuse platelets in presence of bleeding and on the other hand there is a need for its judicious use as the requirement is more than its availability. The study was aimed to assess the clinico-hematological parameters, and the requirement and need for platelet transfusion in children with dengue fever. All children (0-12 yr of age) diagnosed and confirmed with dengue fever at a tertiary care hospital in Puducherry between 1 August 2012 and 31 January 2015 were reviewed retrospectively from hospital case records as per the revised WHO guidelines for dengue fever. The diagnosis was confirmed by NS1 antigen- based ELISA test or dengue serology for IgM and IgG antibodies and the data were analyzed using SPSS 16.0 statistical software. Out of 261 cases of dengue fever, hemorrhagic manifestations were observed in 52 children (19.9%), which mainly included petechiae (38.5%), gum bleeding (34.6%) and melena (26.9%). Thrombocytopenia was seen in 211 (80.8%) cases. Bleeding manifestations were present in 20(39.2%), 8(15.7%), 13(25.5%) and 11(21.6%) cases with platelet count 1.50,000/mm3 respectively. Bleeding manifestations did not always correlate with platelet count in non-severe dengue infection in comparison to severe dengue infection. The most common mode of presentation of severe dengue infection was shock with 102(39.1%) cases and among them only 22 children (21.6%) had bleeding. About 17 children (6.5%) with severe dengue infection required platelet transfusion and out of them, 12 children (70.6%) had a platelet count <20,000/ mm3 whereas five children (29.4%) had platelet count in the range of 20,000-50,000/mm3. Platelet transfusion was required

Full Text Available As fístulas biliares internas espontâneas são comunicações estabelecidas entre qualquer segmento da árvore biliar e dos órgãos abdominais. Elas constituem uma afecção rara apesar de compreender uma complicação da colecistite, patologia freqüente da prática cirúrgica. As fístulas bilioentericas ocorrem em 3-5% dos doentes com colelitíase, sendo 68% destas bilioduodenais. O objetivo desse manuscrito é relatar um caso de fístula bilioduodenal complicada com hemobilia e hemorragia digestiva, descrevendo a conduta adotada. Os dados foram coletados entre dezembro/2015 a abril/2016 através da analise de prontuário fornecido pelo Hospital Universitário Sul Fluminense (HUSF. Trata-se de um paciente masculino, 75 anos, atendido no HUSF-Vassouras/RJ com diagnóstico sindrômico de abdome agudo inflamatório por colecistite aguda, submetido a tratamento conservador para regressão da inflamação peri-colecística, diminuindo assim, o risco de lesões iatrogênicas da árvore biliar em posterior cirurgia. Evoluiu com melena, que foi investigada por endoscopia digestiva alta onde foi observada úlcera de bulbo duodenal com drenagem de secreção purulenta pela sua luz; e tomografia computadorizada de abdome que evidenciou presença de aerobilia indicando presença de fístula bileodigestiva. O tratamento conservador consistiu-se em antibioticoterapia e reposição volêmica, optado devido à remissão do quadro de colecistite após desobstrução pela fístula, devido à hemorragia que cessou espontaneamente e também pelo risco da realização do procedimento cirúrgico em paciente idoso com intensa resposta inflamatória sistêmica. Não é comum na literatura médica a ocorrência de fístulas biliodigestivas com sinais e sintomas hemorrágicos. O quadro clínico geralmente é inespecífico e frequentemente atrasado devido à falta de sinais e sintomas patognomônicos.
Background. There is no literature review on gastroduodenal perforation or ulcer (GDPU) with rotavirus (RV) and norovirus (NoV) gastroenteritis. Methods. Pediatric cases of GDPU or upper gastrointestinal bleeding with RV and NoV gastroenteritis were searched from September 1974 until October 2015 using PubMed, Google for English, other-language-publications, and Ichushi (http://www.jamas.or.jp) for Japanese-language publications. All reports confirming GDPU or upper gastrointestinal bleeding with RV and NoV gastroenteritis were eligible for inclusion in the study. In addition, clinical characteristics were reviewed. Results. A boy with duodenal ulcer (DU) and NoV gastroenteritis was described. There were 32 GDPU cases (23 RVs and 9 NoVs cases), including our case; with the exception of 1 case, all were Japanese. Mean age, male/female ratio, and symptoms' duration before admission were 21.6 months, 2.2, and 4.0 days, respectively. Vomiting was the most common symptom, followed by diarrhea, lethargy, fever, abdominal distension, and convulsion. Dehydration, hematemesis, melena, drowsiness or unconsciousness, shock, metabolic acidosis, leukocytosis, anemia, positive C-reactive protein, high blood urea nitrogen, and hyponatremia commonly occurred. Helicobacter pylori was a minor cause of GDPU. Duodenal (DP) or gastric perforation (GP) developed in 14 cases (10 DP/RVs, 1 GP/RV, and 3 DP/NoVs). Duodenal ulcer or gastric ulcer (GU) developed in 18 cases (10 DU/RVs, 4 DU/NoVs, 1 GU/RV, 1 GU + DU/NoV, and 2 upper gastrointestinal bleeding/RVs). The predominant perforation or ulcer site was in the duodenum. With the exception of 2 deaths from DU, all cases recovered. Conclusions. Race, young age, male, severe dehydration, metabolic acidosis, drowsiness and unconsciousness, and shock may be potential risk factors of GDPU associated with RV and NoV gastroenteritis. Limitation of this descriptive study warrants further investigations to determine the risk factors in

As a contribution to the knowledge of gastric cancer, a study took place at "Victor Ramos Guardia Hospital" in the city of Huaraz (3,100 meters above sea level), from August 1992 to July 1998. 170 cases were reported. All of them had biopsy exam.The accumulated incidence was of 138.2 cases per 100,000. The annual mean was 35.8 cases per year. The endoscopy incidence was of 16.7%. And 100% were advanced cancer. All of them were from the sierra of Ancash. 52.4% were males. 80% came from rural zones. And 91.7% were dedicated to agriculture. Food was mainly tubers, vegetables, ham and other salad meats. Ingestion of fruits was very scarce. Mean age was 60.6 years (32?90). 61.6 for females and 59.8 for males. When diagnosis was made 81.2% referred abdominal pain, 67.4% were pale, 38.2% had hematemesis/ melena, abdominal tumor was found in 37.7% and 28.8% had pyloric syndrome.97.7% of the biopsies were reported as adenocarcinoma. And 2.3% as linfomas. Of the 166 adenocarcinomas, 72.9% were of the intestinal type and 27.1% the diffuse type. The intestinal type was more frequent on males (77.6%) that on females (67.9%). Otherwise the diffuse type was more frequent on females (32.1%) that on males (22.4%). Lesions were classified as Bormann: I (0.6%), II (22.9%); III (62.4%) and IV (14.1%).Gastric cancer was found in the distal body in 41.7% of cases. In 2 regions: antrum and body in 26.5% and in the proximal body in 11.2%. 8.4% was localized in the cardias. The intestinal type was more frequently found an the distal body (77.5%). And on the medium body (73.3%). The diffuse type was mostly found on the proximal body (42.1%). On the following up 30 patients were lost and by April 1999, 95% were dead.We conclude that gastric cancer, probably, has a high incidence in the sierra of Ancash. The onset is of advanced gastric cancer. The intestinal type is predominant. And it is an important cause of disease and mortality in risk population.

The benefits of dual antiplatelet therapy are counterbalanced by the increased incidence of gastrointestinal (GI) complications. The aim of this study was to determine the frequency of GI bleeding, identify the predictors associated with the increased bleeding, and determine the short-term and long-term outcomes. This was an observational, case-control cohort study carried out at the Albert Einstein Medical Center. It included all patients who had a drug-eluting stent implanted between May 2003 and April 2007. A total of 1852 patients were identified; of these 50 patients were readmitted for a GI bleed. A control group of 202 patients who did not have any evidence of GI bleeding were compared with the original group. All data were expressed as mean±SD. The baseline clinical characteristics between the 2 groups were compared using the t test and the Fisher exact test. Multivariate analysis was used to determine the predictors of GI bleeding. The rate of GI bleeding was 2.7%. The mean age in the group with GI bleeding was 70.9±12.2 years, whereas in the group without GI bleeding it was 66.5±12.8 years (P<0.05). The majority of the patients presented with melena (40%). Gastritis and gastric ulcers were the most common findings seen in 49% of the patients on endoscopy. On multivariate logistic regression analysis, a history of GI bleeding was the most important independent predictor of future GI bleeding (P<0.001), whereas the use of statins was found to be protective (95% confidence interval, 0.13-0.48; P<0.001) against future GI bleeding. The 30-day mortality rate in the GI bleeding and control groups was 3.7% and 0%, respectively (P<0.01), whereas in the corresponding 1 year the mortality rate was 18.9% and 0%, respectively (P<0.001). The rate of GI bleeding in patients on dual antiplatelet therapy is low. Earlier history of GI bleeding is the most significant multivariate predictor of future GI bleeding whereas statins seemed to be protective. Patients with GI

Upper gastrointestinal bleeding (UGIB), a potentially fatal occurrence, can sometimes follow coronary artery bypass graft (CABG) surgery. However, little has been published about its prevalence, risk factors, and outcomes. This study aimed to determine the rate, etiologies, predisposing factors, and outcomes of UGIB following CABG. The authors conducted a retrospective chart review of all UGIBs which followed CABGs performed at the University of Alberta Hospital from January 1, 1998 to December 31, 2002. During the study period, 4,502 CABGs were performed at the UAH. Eighteen patients (0.4%) had a documented major UGIB (defined as evidence of melena, red or coffee-grounds emesis, blood per NG tube, or a decrease of Hgb by > 20 g/l and requiring a confirmation by endoscopy or radiological study). Two of these 18 patients (11%) had a past history of peptic ulcer disease, and one of these patients had had previous UGIB. Three patients (17%) had been taking proton pump inhibitors (PPI) before the UGIB occurred. At the time of UGIB, PPIs were prescribed for 16 patients (89%), and the PPIs achieved effective hemostasis as a single agent for 10 (62.5%). Of the 18 patients, 16 (89%) underwent upper GI endoscopy. Bleeding was found to be due to duodenal ulceration in 9 (56%), esophagitis in 4 (22%) and gastritis in 6 cases (33%); fifty percent of these patients had multiple sites of bleeding. Endoscopic therapeutic intervention was needed by 6 patients (37.5%), and successful hemostasis was achieved for 5 of these patients (83%). One patient had a recurrence of bleeding and required surgery. One patient underwent surgery as the primary hemostatic therapy after a diagnostic endoscopy. The overall surgical rate was 11.1% for this patient cohort. In this cohort, three patients died, two from multi-organ failure, and the third, a surgically managed patient, had a cardiac arrest 72 hours post-surgery. The number of complication increased as both cardiopulmonary bypass and cross

NGC 3603 is a giant H II region known to harbor a large population of massive stars. Its central cluster is the closest galactic counterpart to the R136 cluster in 30 Dor, in the Large Magellanic Cloud (Walborn 1973). It is very compact (76 arcsecs in diameter) which makes it an extremely difficult target for individual stars spectroscopy. Some stars lying mostly in the periphery of NGC 3603 have been classified from the ground by Moffat (1983), but for the highly crowded core only one study was available at present (Drissen et al. 1995), which was performed with the Faint Object Spectrograph on board of the Hubble Space Telescope (HST). Among the massive members of NGC 3603 there are some of the objects showing H-rich WN + abs spectra, also found in the R136 cluster in 30 Doradus (Massey & Hunter 1998). During 2 nights in April 2006, we have made use of the excellent seeing and large aperture of the Magellan telescopes to obtain individual spectroscopy for stars in the crowded core of NGC 3603. We used the IMACS spectrograph in F4 mode at the Baade (Magellan I) telescope, with a 600 l/mm grating and a 0.7 arcsec long slit. From these observations we were able to derive new spectral types for 26 stars: 16 of which are classified here for the first time, while for the remaining 10 we have revised previous spectral classifications, finding very good general agreement, but exact coincidence for only 2 of them. This rises to 38 the number of stars in this massive star forming region, for which spectral classification is available. Not surprisingly, most of the newly classified spectra belong to the earliest O-subtypes. This work is part of a more comprehensive study (Melena et al. 2007) in which archival HST/ACS-HRC images (P.I. Maiz-Apellaniz) have been used to derive new photometry for stars in the cluster, including those for which there is spectroscopy. Having new spectral types and improved photometry, allowed us to determine new values for the reddening (E (B

Background and Objectives: Crimean-Congo Hemorrhagic fever (CCHF is a viral disease transmitted to ruminants or human by the bite of mature tick vectors. It can be transmitted through contact with the infectious blood or viraemic tissues during slaughter and hospital contacts. 80% of the cases are sub clinical and the rest of them are presenting with an acute febrile and occasionally hemorrhagic disease. The mortality rate of the fulminate form of the disease is equal to 20% to 50%. The hemorrhage is usually in the form of hematoma, melena, nose, conjunctiva, uterine or subcutaneous bleeding. CCHF complications are: encephalitis, optic neuropathy, hepatitis, renal failure and myocardial necrosis.
Case Report: In this article, we’ve discussed a CCHF patient who presented with high fever, myalgia, headache, nausea, vomiting, abdominal pain, diffuse cutaneous and gingival hemorrhage during the course of the disease while the patient was hospitalized. Profound jaundice, petechia and global ecchymosis were considerable. Lab data showed at the beginning of hospitalization that the number of liver enzymes was increased up to 8-10 times. The number of placates were lower than 150000 ml. Moreover, during the first three days there was a decrease in the number of white blood cells and PTT was abnormal. (AST was higher than 100 units per litre. The results of serologic examination of IgM- ELISA virus for CCHF on day 5 and IgG-ELISA on day 10–which were carried out in pasture Institute-were reported to be positive. According to the patient’s history and clinical symptoms, he was also suspicious for Brucellosis and the lab data demonstrated that he is also infected with Brucella.

O tratamento usual envolve a administração de FVIII humano ou recombinante parcialmente ativado eventualmente associados a imunossupressores. Relato do caso: Paciente, 86 anos, masculino, chegou ao PS com equimoses e hematomas pelo corpo. Evoluiu com obstrução da cavidade oral e entrou em insuficiência respiratória. Foi necessária traqueostomia. Exames laboratoriais: hemograma normal com leve queda da hemoglobina. Tempo de Protrombina Normal e TTPa > 100 seg. Solicitada a dosagem de Fator VIII e de inibidor se apresentando a 2% e presença de anticorpo anti-Fator VIII. O paciente recebeu Plasma Fresco Congelado e Crioprecipitado nos primeiros dias sem melhora e, após a chegada da dosagem do Fator e inibidor, foi iniciada imunossupressão com Solumedrol 1g EV por 3 dias seguido de Prednisona 1 a 2 mg/Kg. Dias depois iniciada Azathioprina, 50mg/dia e depois 100 mg/dia, além de FEIBA de acordo com a ocorrência de sangramentos. Evoluiu com melena, enterorragia e queda importante da hemoglobina, necessitando de transfusões. Após cerca de 30 dias do início da imunossupressão, foi observado resolução do quadro hemorrágico, redução do TTPa para cerca de 50 segundos e elevação do nível do FVIII para 8%. Conclusão: A imunossupressão foi essencial e conseguiu diminuir o título dos anticorpos e elevou os níveis de Fator VIII, resolvendo o quadro hemorrágico, mas isso só ocorreu após um mês de seu início. O suporte com fatores ativados foi crucial neste caso até que a imunossupressão fizesse efeito. Temia-se por eventos tromboembólicos que ocorreram tardiamente e, por isso, acreditamos ser um evento não relacionado a ele
Acute GI bleeding by multiple jejunal gastrointestinal autonomic nerve tumour associated with neurofibromatosis type I Urgencia quirúrgica por sangrado intestinal debido a tumor intestinal de nervios autónomos asociados a neurofibromatosis tipo I
Full Text Available We describe a surgical emergency due to GI-bleeding caused by gastrointestinal autonomic nerve tumours (GANT's in a patient with von Recklinghausen's disease. A 72 year old female patient with von Recklinghausen's disease was admitted with maelena. Endoscopy showed no active bleeding in the stomach and the colon. Therefore an angio-CT-scan was performed which revealed masses of the proximal jejunum as source of bleeding. Laparotomy was indicated and a 20 cm segment of jejunum which carried multiple extraluminal tumours was resected. The source of the bleeding was a 2 cm tumour which had eroded the mucosal surface. Immunohistologically, evidence of neuronal differentiation could be shown in the spindle-formed cells with positive staining for C-Kit (CD 117, CD 34, and a locally positive staining for synaptophysine and S100. This case report illustrates the association between neurofibromatosis and stromal tumours and should alert surgeons and gastroenterologist about gastrointestinal manifestations in patients with von Recklinghausen's disease.Se describe una urgencia quirúrgica por sangrado intestinal debido a tumor gastrointestinal de nervios autónomos (GANT asociado a enfermedad de von Recklinghausen.

Different oral anticoagulants may be associated with gastrointestinal bleeding (GIB) from different locations or mucosal lesions. We aimed to test this hypothesis. Two blinded gastroenterologists independently analyzed source documents from the randomized evaluation of long-term anticoagulant therapy (RE-LY) trial of dabigatran 150 mg BID (D150), dabigatran 110 mg BID (D110) versus warfarin in non-valvular atrial fibrillation (NVAF). Major GIB events (total n = 546) and life-threatening GIB events (n = 258) were more common with D150 versus warfarin (RR 1.57 [1.28-1.92] and RR 1.62 [1.20-2.18], respectively) and similar for D110 compared to warfarin (RR 1.11 [0.89-1.38] and RR 1.16 [0.84-1.61], respectively). Fatal bleeding was similarly rare across treatment groups. Lower GI major bleeding and life-threatening bleeding were more common with D150 compared to warfarin (RR 2.23 [1.47, 3.38] and RR 2.64 [1.36, 5.13], respectively) and with D110 compared to warfarin (RR 1.78 [1.16, 2.75] and RR 2.00 [1.00, 4.00], respectively). MGIB from colonic angiodysplasia was increased with dabigatran versus warfarin (P < 0.01 for both dose comparisons). Subacute and chronic MGIB events were more common with D150 than with warfarin (RR 1.72 [1.06, 2.78] and RR 1.66 [1.12, 2.45], respectively), as were hematochezia or melena (RR 1.67 [1.18, 2.36] and RR 1.72 [1.20, 2.47], respectively). In a chronic NVAF population, D150 but not D110 is associated with increased major and life-threatening GI bleeding in comparison with warfarin. At both dabigatran doses, increased bleeding from the colorectum, in particular from angiodysplasia, is seen.

Objective: To investigate the value of MR enteroclysis with air infusion in the diagnosis of small bowel disease. Methods: Sixteen patients with suspected small bowel disease, but without acute inflammatory disease or bowel obstruction, received MR enteroclysis with air infusion. There were 12 males and 4 females, and their age ranged from 17 to 75 years. 10 patients had abdominal pain, 4 with melena or blood stool, and 2 with diarrhea. The longest course was 7 years, and the shortest 1 week. Before MR imaging, a nasoenteric catheter was inserted into the distal part of duodenum, and about 1000 ml of air was infused through the tube to distend the small bowel. 20 mg of IV anisodamine was given to reduce small-bowel peristalsis. All patients were imaged with fat-saturated Gd-DTPA enhanced coronal and axial T 1 -weighted spin-echo (SE) sequence and fast spoiled gradient echo (FSPGR) sequence. Comparison between the diagnosis of MRI and the results of surgery, pathology or clinic was performed to assess the sensitivity and specificity of MRI. Results: 5 cases were normal, 6 with Crohn disease, 2 with gastric intestinal stromal tumor (GIST), and 1 each of lymphoma, tuberculosis and irritable bowel syndrome. The lumen of normal small bowel in MR enteroclysis was no signal, the wall was outlined as middle signal by intraluminal air and surrounding air-distended bowel and was between 1-3 mm thick, and the diameter of the lumen was between 17-28 mm. Crohn disease showed segmental mural thickening, increased enhancement, luminal stricture, and even extraluminal inflammatory mass or fistula. Intestinal tuberculosis invaded the distal section of ileum, cecum, and the proximal ascending colon, the wall thickened and enhanced apparently, and cecum and proximal ascending colon shortened. GIST showed a mass that was iso-signal on T 1 WI, high signal on T 2 WI, and enhanced significantly after IV Gd-DTPA. 1 recurrent lymphoma of ileum showed mural thickening and increased

Methods Clinical, hematological and serological infonnation from children diagnosed v.ith dengue infection in Cipto Mangunkusumo Hospital were collected from 2007 to 2009. Results Of611 children admitted with dengue, 143 (23.4% had dengue fever (DF, 252 (41.2% had DHF grades I and II; and 216 (35.4% had DHF grades III and IV. Of the 81 cases where dengue serotypes were identified, 12.3% were DENV1, 35.8% were DENV-2, 48.2% were DENV-3 and 3.7% were DENV-4. Mean age of subjects was 8.9 years (SD 4.4, and 48.4% of cases were boys. The mean length of fever before hospital admission was 4.2 days (SD 1.1 and mean length of stay in the hospital was 4 days (SD 2.7. Common symptoms observed were petechiae, hepatomegaly and epistaxis. Complications found mostly in those with dengue shock syndrome (DSS were hematemesis (30 cases, 4.9% of all patients, encephalopathy (19 cases, 3.1 % and melena (17 cases, 2.8%. Conclusion Signs and symptoms of fever, bleeding manifestations and thrombocytopenia were present in children 'With DF and DHF, while signs of increased vascular permeability were found only in those 'With DHF. Encephalopathy and gastrointestinal bleeding were found mostly in DSS cases. At admission, leukopenia was found in more DF patients than in DHF patients. Absence of leukopenia may be a sign of more severe dengue infection.

Gastric Gist's account for more than half of all gastrointestinal stromal tumors and represent less than 5% of all gastric tumors. The peak age for harboring Gist of the stomach is around 60 years and a slight male preponderance is reported. These tumors are identified by expression of CD117 or CD34 antigen. Symptoms at presentation usually include bleeding, ab¬dominal pain or abdominal mass. Endoscopically, they typically appear as a submucosal mass with or without ulceration and on CT scans an extra gastric mass is usually seen. Complete surgical resection provides the only chance for cure, with only l-2 cm free margins needed. However, local recurrence and/or metastases supervene in almost half the patients treated with surgery alone, even when no gross residual is left. Thereby imatinib mesylate was advocated as an adjuvant to surgery, which appears to have improved disease-free and overall survival. Aim of the Work: The aim of this work was to assess clinico-pathological features of gastrointestinal stromal tumors (GIST) of the stomach and to appraise the results of treatment by surgery in patients treated at the National Cancer Institute (NCI) of Cairo between January 2002 and December 2007. Patients and Methods: Nineteen patients with histologically and immuno-histochemically proven GIST of the stomach were treated by surgery at the NCI during the 6-year study period. Preoperative assessment included detailed history, clinical examination, full laboratory tests, endoscopy, abdominal ultrasound and CT. General medical assessment included chest X-ray, ECG and echocardiography. Results: The patients' age ranged from 26 to 77 years with a median of 51 years. Obvious male/female preponderance was noticed (68.4% to 31.6%). Tumors were located at the upper 1/3 in 42.1%, at the middle 1/3 in 31.6% and at the lower 1/3 in 26.3%. The most common clinical presentation was related to bleeding (hematemesis, melena or anaemia) and was seen in 63.2%. No tumors were

Gastrointestinal bleeding is a well-known risk of systemic anticoagulation. However, bleeding in the setting of supratherapeutic anticoagulation may have a milder natural history than unprovoked bleeding. It is a common clinical gestalt that endoscopy is common, but bleeding source identification or intervention is uncommon, yet few data exist to inform this clinical impression. Consequently, we sought to examine our institutional experience with gastrointestinal bleeding in the setting of supratherapeutic international normalized ratio (INR) with the aim of identifying predictors of endoscopically identifiable lesions, interventions, and outcomes. A retrospective review was conducted at a tertiary referral academic medical center to identify patients presenting with gastrointestinal bleeding in the setting of warfarin and a supratherapeutic INR (>3.5) who underwent an endoscopic procedure. Relevant clinical covariates, endoscopic findings, need for intervention, and outcomes were collected by review of the medical record. Logistic regression adjusting for potential confounders identified predictors of endoscopically significant lesions as well as intervention and outcomes. A total of 134 patients with INR 3.5 or greater (mean 5.5, range 3.5-17.1) presented with symptoms of gastrointestinal bleeding, most commonly as melena or symptomatic anemia. Antiplatelet agents were used by 54% of patients, and 60% of patients were on concomitant acid suppression on admission. Procedures included esophagogastroduodenoscopy (upper endoscopy; EGD) (n = 128), colonoscopy (n = 73), and video capsule endoscopy (n = 32). Active bleeding at first EGD or colonoscopy was found in only 19 patients (18%), with endoscopic intervention in only 26 patients (25%). At a critical threshold of INR 7.5 at presentation, the likelihood of finding an endoscopically significant lesion fell to therapy (odds ratio [OR] 2.59; 95% confidence interval [CI], 1.13-5.94), timing of EGD within 12 hours of

Disseminated intravascular coagulopathy (DIC) is characterized as activation of the clotting system resulting in fibrin thrombi, gradually diminishing levels of clotting factors with increased risk of bleeding. Basically two types of DIC are distinguished: (1) chronic (compensated) - with alteration of laboratory values and (2) acute (non-compensated) - with severe clinical manifestations: bleeding, shock, acute renal failure (ARF), transient focal neurologic deficit, delirium or coma. Chronic DIC related to metastatic neoplasia is caused by pancreatic, gastric or prostatic carcinoma in most of the cases. Incidence rate of DIC is 13-30% in prostate cancer, among those only 0.4-1.65% of patients had clinical signs and symptoms of DIC. In other words, chronic DIC is developed in one of eight patients with prostate cancer. DIC is considered as a poor prognostic factor in prostatic carcinoma. The similar clinical and laboratory findings of TTP-HUS (thrombotic thrombocytopenic purpura - hemolytic uremic syndrome) and DIC makes it difficult to differentiate between them. A 71 years old male patient with known chronic obstructive pulmonary disease, benign prostatic hyperplasia, significant carotid artery stenosis, gastric ulcer and alcoholic liver disease was admitted to another hospital with melena. Gastroscopy revealed intact gastric mucosa and actually non-bleeding duodenal ulcer covered by clots. Laboratory results showed hyperkalemia, elevated kidney function tests, indirect hyperbilirubinemia, increased liver function tests, leukocytosis, anemia, thrombocytopenia and elevated international normalized ratio (INR). He was treated with saline infusions, four units of red blood cells and one unit of fresh frozen plasma transfusions. Four days later he was transported to our Institution with ARF. Physical examination revealed dyspnoe, petechiae, hemoptoe, oliguria, chest-wall pain and aggressive behavior. Thrombocytopenia, signs of MAHA (fragmentocytes and helmet cells
In Peru, the incidence of gastric cancer is reported to be around 15.8 per 100,000 inhabitants and it is the second most common oncological disease in men and the third one in women. Additionally, a high mortality index was reported, especially among poor people. To address this issue, in 2008, Peru initiated several insurance treatment plans of oncological diseases with promising results. In Mexico, there is a high predominance of gastric cancer in male gender compared to female gender, even reaching a 2/1 ratio, and the detection rate of early gastric cancer is low (10% to 20%) which results in a mainly palliative treatment with an overall survival rate in 5 years about 10% to 15% only. In Peru, the average age at diagnosis is around 62.96±14.75 years old and the most frequent symptoms includes abdominal pain, indigestion, loss of appetite, weight loss and gastrointestinal bleeding, while in Mexico, some studies reported an average age at diagnosis around 60.3±4.1 years old (range, 23-78 years old) and the most frequent symptoms were postprandial fullness (74.4%), abdominal pain (37.2%), weight loss (18.6%), and melena (4.6%). The anemia rate was 65.1% with a mean Hb level of 6.14 g/dL. In Peru, the most common gastric cancer type is the intestinal-type adenocarcinoma (around 34%), followed by the diffuse-type adenocarcinoma (18.7%), whilst among Mexicans, the diffuse-type was reported in 55.2% of cases, the intestinal-type was reported in 28.2% and the undifferentiated-type corresponded to 6%. In both, Peru and Mexico, 90% of the associated factors includes tabaquismo, diets rich in salt, smoked foods, and a sedentary lifestyle. Family inheritance and advanced age and pharmacological-resistant Helicobacter pylori infection are also important. Poverty has been heavily associated with a higher incidence of gastric cancer. The management of gastric cancer patients in Peru is carried out by general surgeons or general surgical oncologists. In recent years, efforts

Objective: In recent years, a large proportion of non-Hodgkin's lymphomas of the stomach are recognized as low grade tumors of the mucosa associated lymphoid tissue (MALT) type. Since the MALT morphological subtype has only gained acceptance as a malignant lymphoma after the establishment of the Working Formulation, there is limited information about its natural history, disease pattern, and longterm treatment outcome. This study is an analysis of these parameters in patients with primary MALT lymphoma of the stomach. Materials and Methods: Consecutive patients with primary gastric MALT lymphoma who received definitive treatment at the Massachusetts General Hospital between (4(78)) and (2(95)) were included in the study. The diagnosis was pathologically verified in all cases. Clinical staging studies included chest X-ray +/- chest CT, abdomino-pelvic CT or bipedal lymphangiogram, barium swallow, and bone marrow biopsy. Treatment strategies included combinations of partial or total gastrectomy, radiation (RT) and chemotherapy (chemo). RT was given via multifield technique, with 10-25MV photons, to doses of 36-50.4 Gy (1.1-1.8 Gy per fraction, 5 days a week). Survival analyses were performed by the Kaplan-Meier actuarial method. Results: There were twenty-two patients between the ages of 45 - 93 years, with a mean follow-up of 67 months. Ten were male and 12 female. The most frequent presenting symptoms were epigastric pain (77%), dyspepsia (65%), and melena (41%). The mean duration of symptoms was 27 months. Eighteen cases were clinical stage (cs)I, two csII, one csIII, and one csIV. The treatment approaches were: 1) csI:6 gastrectomy alone, 7 gastrectomy and RT, 1 gastrectomy and chemo, 2 RT alone, 1 chemo and RT, 1 no therapy; 2) csII: 2 gastrectomy and RT; 3) csIII: 1 gastrectomy and chemo; 4) csIV: 1 chemo and RT. Among 16 gastrectomy specimens, multifocal gastric involvement was evident in 50%. The most frequently involved sites were the body (63%) and antrum

accomplished. In group I there were no significative alterations. In group II, all the dogs showed moderate episodes of vomit and diarrhea. The blood-cell profile was not modified. Two dogs had hematocrit and hemoglobin reduction. In the necropsy, hemorrhagic spots and moderate gastroduodenal lesions were seen. The microscopic analysis revealed the presence of gastritis and ulcerative enteritis. In group III, four dogs (80% showed vomit and diarrhea, without alteration in blood-cell profile. The microscopic analysis showed mild lesions in the gastric mucosa and hemorrhagic spots in the duodenum of four dogs. Histology showed lesions suggesting mild gastroenteritis. In group IV, all the dogs (n=5 showed vomit and blood diarrhea. Four of them showed anemia (p <0.05. Four and five dogs, respectively, had hematocrit and hemoglobin reduction. In addition, there was a significant (p<0.05 leukocytosis, neutrophilia and linfopenia in 60% of the dogs. The necropsy showed hiperemia, hemorrhage and severe gastric ulcers in all the dogs. In the microscopic analyses, gastroenteritis ulcerative was present in all the animals. In group V, the dogs (n=5 had serious vomit, diarrhea and melena episodes. The dogs that bore the treatment (n=4 had anemia and leukocytosis with neutrophilia and linfopenia significatives (p<0.05. All the dogs had hematocrit and hemoglobin reduction. In the necropsy, hemorrhages and severe gastroduodenal ulceration were seen. The microscopic analysis showed severe gastroenteritis. It can be concluded that, although meloxicam is a COX-2 selective inhibitor, it induces deleterious effects on gastrointestinal tract and blood cells of dogs, when given five or ten times the therapeutic dose, which demonstrate its low margin of safety in this animal specie.

Full Text Available Duas amostras brasileiras do vírus da Diarréia Viral Bovina tipo 2 (BVDV-2 foram inoculadas em bezerros com o objetivo de avaliar a sua virulência e estudar a patogenia da infecção. Previamente à inoculação, os animais foram imunodeprimidos com dexametasona. Quatro bezerros com idades entre 45 e 90 dias (grupo A foram inoculados com a amostra SV-260 (n=2 ou LV-96 (n=2 e quatro bezerros com 6 a 8 meses de idade foram inoculados com a amostra SV-260 (grupo B. Após a inoculação, os bezerros do grupo A apresentaram anorexia, depressão, hipertermia, sinais de infecção respiratória e diarréia profusa, acompanhada de melena em dois animais. Os sinais respiratórios e digestivos progrediram, e os animais morreram ou foram sacrificados in extremis entre os dias 7 e 12 pós-inoculação. Úlceras e erosões no trato digestivo (língua, n=4; esôfago, n=1; rúmen, n=1 e abomaso, n=3, edema pulmonar (n=4 e na mucosa do abomaso (n=3; equimoses e sufusões na serosa do baço (n=2, no rúmen, no intestino delgado e no ceco (n=1, no coração (n=1 e na mucosa da bexiga (n=1 e intussuscepção intestinal (n=1 foram os achados macroscópicos mais marcantes. Úlceras e erosões, acompanhadas de infiltrado mononuclear na mucosa e submucosa do trato digestivo e depleção linfóide nos linfonodos e placas de Peyer, foram as alterações microscópicas mais freqüentes. O vírus foi detectado em vários tecidos e órgãos. Antígenos virais foram demonstrados por imuno-histoquímica, principalmente em células epiteliais do trato digestivo; em células mononucleares nos espaços perivasculares e peribronquiais; na cápsula e septos de linfonodos; e em linfócitos e células mononucleares das placas de Peyer e baço. Os animais do grupo B apresentaram depressão, hipertermia, sinais moderados de infecção respiratória e digestiva, ulcerações na língua e bochecha, mas recuperaram-se após alguns dias. Esses resultados demonstram que as amostras de
