    Acute gastrointestinal hemorrhage is a common problem that requires prompt recognition and management to prevent serious morbidity and mortality. Management goals are stabilization of the patient with vigorous fluid resuscitation followed by investigation and definitive treatment of the bleeding source. Endoscopy is often the initial diagnostic test and allows therapeutic measures to be performed at the same time. Images Figure 1 Figure 2 PMID:8563510

    Selective serotonin reuptake inhibitors (SSRI) are widely used antidepressants characterized by less-frequent adverse effects compared with classical anti-depressive agents. On the other hand, SSRI can cause hemorrhagic events more due to impaired platelet aggregation induced by a depletion of serotonin in the peripheral platelet. Epidemiological studies have indicated that patients taking SSRI are predisposed to gastrointestinal hemorrhage, especially in case that nonsteroidal anti-inflammatory drugs are prescribed concomitantly. Here we describe a risk of the gastrointestinal hemorrhage in patients taking SSRI.

    Poisoning, both accidental and intentional, is a significant contributor to the mortality and morbidity throughout the world. The commonest pesticide poisoning is organophosphates followed by phosphides. Ingestion of phosphides can induce severe gastrointestinal irritation leading to hemorrhage and ulcerations. Gastrointestinal hemorrhages and ulcerations beyond the duodenum have not been reported in the literature. Here, we report a case of severe hemorrhages and ulcerations in stomach, duodenum, jejunum, and ileum observed in a 45-year-old male who had consumed five tablets of Celphos(®) (each 3 g with 56% aluminum phosphide and 44% Ammonium carbonate) to commit suicide. He started vomiting after consumption, and the vomitus was blood-tinged. Once the treatment was instituted, he was stable for a day and thereafter his condition gradually deteriorated. He died on the 4th day of hospitalization, and autopsy revealed features of multiorgan failure and extensive gastrointestinal hemorrhages.

    In the past few years gastric resection has become the therapy of choice for patients with massive hemorrhage from duodenal ulcer. When this is done as an emergency procedure the ability of the surgeon is often taxed to the limit. Although sometimes easy, control is often extraordinarily difficult. Many important technical details must be considered in order to attain a successful outcome. This method of therapy has proved to be very satisfactory with patients who are in good condition for operation, and even in the poorer risks seen on ward service has resulted in a surgical mortality of only 7 per cent in all patients less than 60 years of age treated for this extremely severe type of hemorrhage. In the older age groups mortality rates still remain high. PMID:13284635

    Cystic dystrophy of the duodenal wall (CDDW) is a complication of heterotopic pancreatic tissue located in the wall of the gastrointestinal tract, characterized by the presence of multiple small cysts, usually found in the wall of the second part of the duodenum. Gastrointestinal hemorrhage due to CDDW is a rare complication. We report the case of a 50-year-old man who was admitted to our hospital for persistent vomiting. The imaging tests confirmed the diagnosis of CDDW. During his stay in hospital, the patient had a gastrointestinal hemorrhage secondary to this disorder, which made it necessary to perform a Roux-en-Y gastrojejunostomy (Billroth III). PMID:27957010

    Endovascular embolization has been used to control gastrointestinal tumor bleeding. Lots of embolic agents have been applied in embolization, but liquid embolic materials such as Onyx have been rarely used because of concerns about severe ischemic complications. To evaluate the clinical efficacy and safety of transcatheter arterial embolization (TAE) with Onyx for acute gastrointestinal tumor hemorrhage. Between September 2011 and July 2013, nine patients were diagnosed as acute gastrointestinal tumor hemorrhage by clinical feature and imaging examination. The angiographic findings were extravasation of contrast media in the five patients. The site of hemorrhage included upper gastrointestinal bleeding in seven cases and lower gastrointestinal bleeding in two cases. TAE was performed using Onyx in all the patients, and the blood pressure and heart rate were monitored, the angiographic and clinical success rate, recurrent bleeding rate, procedure related complications and clinical outcomes were evaluated after therapy. The clinical parameters and embolization data were studied retrospectively. All the patients (100%) who underwent TAE with Onyx achieved complete hemostasis without rebleeding and the patients were discharged after clinical improvement without a second surgery. No one of the patients expired during the hospital course. All the patients were discharged after clinical improvement without a second surgery. Postembolization bowel ischemia or necrosis was not observed in any of the patients who received TAE with Onyx. TAE with Onyx is a highly effective and safe treatment modality for acute gastrointestinal tumor hemorrhage, even with pre-existing coagulopathy.

    Gastrointestinal (GI) bleeding refers to any hemorrhage ascribed to the pathologies of the gastrointestinal tract, extending from the mouth to the anal canal. Despite the recent improvements in the endoscopic, hemostatic and adjuvant pharmacologic techniques, the reported mortality is still around 5%-10% for peptic ulcer bleeding and about 15%-20% for variceal hemorrhages. Although endoscopic management reduces the rates of re-bleeding, surgery, and mortality in active bleeding; early recurrence ratios still occur in around 20% of the cases even with effective initial hemostatic measures. In this quest for an alternative pro-hemostatic agent for the management of GI bleedings, Ankaferd blood stopper (ABS) offers a successful candidate, specifically for “difficult-to-manage” situations as evidenced by data presented in several studies. ABS is a standardized mixture of the plants Thymus vulgaris, Glycyrrhiza glabra, Vitis vinifera, Alpinia officinarum, and Urtica dioica. It is effective in both bleeding individuals with normal hemostatic parameters and in patients with deficient primary and/or secondary hemostasis. ABS also modulates the cellular apoptotic responses to hemorrhagic stress, as well as hemostatic hemodynamic activity. Through its effects on the endothelium, blood cells, angiogenesis, cellular proliferation, vascular dynamics, and wound healing, ABS is now becoming an effective alternative hemostatic medicine for gastrointestinal bleedings that are resistant to conventional anti-hemorrhagic measurements. The aim of this review is to outline current literature experience suggesting the place of ABS in the management of GI bleeding, and potential future controlled trials in this complicated field.

    Gastrointestinal and abdominal bleeding can lead to life-threatening situations. Embolization is considered a feasible and safe treatment option. The relevance of surgery has thus diminished in the past. The aim of the present study was to evaluate the role of surgery in the management of patients after embolization. We performed a retrospective single-center analysis of outcomes after transarterial embolization of acute abdominal and gastrointestinal hemorrhage between January 2009 and December 2012 at the Sisters of Charity Hospital, Linz. Patients were divided into three groups, as follows: upper gastrointestinal bleeding (UGIB), lower gastrointestinal bleeding (LGIB), and abdominal hemorrhage. Fifty-four patients with 55 bleeding events were included. The bleeding source could be localized angiographically in 80 %, and the primary clinical success rate of embolization was 81.8 % (45/55 cases). Early recurrent bleeding (<30 days) occurred in 18.2 % (10/55) of the patients, and delayed recurrent hemorrhage (>30 days) developed in 3.6 % (2/55). The mean follow-up was 8.4 months, and data were available for 85.2 % (46/54) of the patients. Surgery after embolization was required in 20.4 % of these patients (11/54). Failure to localize the bleeding site was identified as predictive of recurrent bleeding (p = 0.009). More than one embolization effort increased the risk of complications (p = 0.02) and rebleeding (p = 0.07). Surgery still has an important role after embolization in patients with gastrointestinal and abdominal hemorrhage. One of five patients required surgery in cases of early and delayed rebleeding or because of ischemic complications (2/55 both had ischemic damage of the gallbladder) and bleeding consequences.

    The incidence rate of the upper gastrointestinal haemorrhage in Nowy Sacz region in years 1991-1995 was 43.5/100 thousand/year among men and 20.1/100 thousand/year among women. The most common causes of bleeding among male were: duodenal ulcer, gastric ulcer and haemorrhagic gastritis. Among female gastric ulcer was more frequent than duodenal ulcer. In the whole group of haemorrhage, the average age of men was lower than the age of women. In similar, in the bleeding duodenal ulcer, gastric ulcer, haemorrhagic gastritis and gastric cancer groups--male were significantly younger.

    ObjectiveThis study was designed to evaluate the role of a negative computed tomography angiogram (CTA) in patients who present with gastrointestinal (GI) hemorrhage.MethodsA review of all patients who had CTAs for GI hemorrhage over an 8-year period from January 2005 to December 2012 was performed. Data for patient demographics, location of hemorrhage, hemodynamic stability, and details of angiograms and/or the embolization procedure were obtained from the CRIS/PACS database, interventional radiology database, secure electronic medical records, and patient’s clinical notes.ResultsA total of 180 patients had 202 CTAs during the 8-year period: 87 CTAs were performed for upper GI hemorrhage (18 positive for active bleeding, 69 negative) and 115 for lower GI hemorrhage (37 positive for active bleeding, 78 negative); 58.7 % (37/63) of patients with upper GI bleed and 77.4 % (48/62) of patients with lower GI bleed who had an initial negative CTA did not rebleed without the need for radiological or surgical intervention. This difference was statistically significant (p = 0.04). The relative risk of rebleeding, following a negative CTA, in lower GI bleeding versus upper GI bleeding patients is 0.55 (95 % confidence interval 0.32–0.95).ConclusionsPatients with upper GI bleed who had negative CTAs usually require further intervention to stop the bleeding. In contrast, most patients presenting with lower GI hemorrhage who had a negative first CTA were less likely to rebleed.

    Upper gastrointestinal hemorrhage (UGIH) is an urgent disease that is often encountered in daily medical practice. Endoscopic hemostasis is currently indispensable for the treatment of UGIH. Initially, when UGIH is suspected, a cause of UGIH is presumed from the medical interview and physical findings. After ample primary treatment, urgent endoscopy is performed. Many methods of endoscopic hemostasis are in wide use, including hemoclip, injection and thermo-coagulation methods. Although UGIH develops from a wide variety of diseases, such as esophageal varices and gastric and duodenal ulcer, hemostasis is almost always possible. Identification of the causative diseases, primary treatment and characteristic features of endoscopic hemostasis are needed to allow appropriate treatment. PMID:21160691

    A self-expanding metallic stent (Wallstent) was used to relieve obstruction of the common bile duct in a young male with a desmoplastic small cell tumor of the abdomen. Two months after insertion and following a course of chemotherapy the lower end of the stent eroded the mucosa of the second part of the duodenum causing severe gastrointestinal hemorrhage which necessitated laparotomy and trimming of the stent. This complication may have been due to shrinking of the tumor as well as thrombocytopenia following chemotherapy.

    We report a case of severe, refractory gastrointestinal (GI) bleeding in a patient with hereditary hemorrhagic telangiectasia (HHT) whose massive transfusion dependence was lifted shortly after treatment with bevacizumab, an anti-vascular endothelial growth factor. The patient’s bleeding had been refractory to repeated endoscopic interventions, tranexamic acid, and tamoxifen. However, following treatment with bevacizumab at 5 mg/kg every other week, nearly 300 units of packed red blood cell transfusions were avoided in one year’s time. Despite its relatively high cost, bevacizumab may have a more active role in the management of severe GI bleeding in HHT if such remarkable response can be consistently demonstrated. PMID:28070235

    Massive gastrointestinal hemorrhage secondary to metastatic renal cell carcinoma involving the jejunum is rare but has been previously described in the medical literature. Treatment options for metastatic renal cell carcinoma are limited, but transcatheter arterial embolization can be performed to control gastrointestinal hemorrhage either alone or prior to surgical resection. We describe a case of successful transcatheter arterial embolization for control of massive gastrointestinal hemorrhage secondary to locally recurrent renal cell carcinoma invading the jejunum and review the literature. Arteriography provided both the diagnosis of recurrent disease and the means of therapy.

    Lower gastrointestinal hemorrhage remains a common disease, frequently presenting with acute life-threatening symptoms. Although prompt detection and treatment are imperative, it is difficult to diagnose lower gastrointestinal hemorrhage in an accurate and efficient manner. Most available modalities are time consuming. Computed tomographic angiography of the abdomen and pelvis, on the other hand, has the unique capability of rapidly detecting whether life-threatening hemorrhage is occurring and accurately localizing it, thus facilitating definitive treatment. We present a case in which computed tomographic angiography was invaluable in the detection and subsequent empirical transarterial embolization of a lower gastrointestinal hemorrhage and offer evidence as to why it should be a first-line tool in the management of these patients.

    This Guideline is an official statement of the European Society of Gastrointestinal Endoscopy (ESGE). It addresses the diagnosis and management of nonvariceal upper gastrointestinal hemorrhage (NVUGIH). Main Recommendations MR1. ESGE recommends immediate assessment of hemodynamic status in patients who present with acute upper gastrointestinal hemorrhage (UGIH), with prompt intravascular volume replacement initially using crystalloid fluids if hemodynamic instability exists (strong recommendation, moderate quality evidence). MR2. ESGE recommends a restrictive red blood cell transfusion strategy that aims for a target hemoglobin between 7 g/dL and 9 g/dL. A higher target hemoglobin should be considered in patients with significant co-morbidity (e. g., ischemic cardiovascular disease) (strong recommendation, moderate quality evidence). MR3. ESGE recommends the use of the Glasgow-Blatchford Score (GBS) for pre-endoscopy risk stratification. Outpatients determined to be at very low risk, based upon a GBS score of 0 - 1, do not require early endoscopy nor hospital admission. Discharged patients should be informed of the risk of recurrent bleeding and be advised to maintain contact with the discharging hospital (strong recommendation, moderate quality evidence). MR4. ESGE recommends initiating high dose intravenous proton pump inhibitors (PPI), intravenous bolus followed by continuous infusion (80 mg then 8 mg/hour), in patients presenting with acute UGIH awaiting upper endoscopy. However, PPI infusion should not delay the performance of early endoscopy (strong recommendation, high quality evidence). MR5. ESGE does not recommend the routine use of nasogastric or orogastric aspiration/lavage in patients presenting with acute UGIH (strong recommendation, moderate quality evidence). MR6. ESGE recommends intravenous erythromycin (single dose, 250 mg given 30 - 120 minutes prior to upper gastrointestinal [GI] endoscopy) in patients with clinically severe

    Early attempts of using embolization for lower gastrointestinal hemorrhage were fraught with complications, most notably ischemic colitis or bowel infarction. Embolotherapy was eventually abandoned in favor of catheter-directed vasoconstriction (i.e., vasopressin infusion). This latter therapy is time and labor intensive. With the advent of microcatheter technology, superselective embolization emerged and is rapidly becoming the endovascular therapy of choice for patients with severe lower gastrointestinal hemorrhage refractory to medical management. Numerous studies on the subject have consistently reported high clinical success with low ischemic complications. This article will review the current status of co-axial microcatheter embolization with an emphasis on the technical aspects of the procedure.

    Primary aortodigestive fistulas (PAFs) are a rare cause of gastrointestinal bleeding, with an incidence of 0.04-0.07% in autopsy series. The diagnosis of PAF is difficult and should be considered in patients with gastrointestinal hemorrhage of obscure origin. Because of its high mortality rate, clinical recognition of prodromal symptoms for early diagnosis is crucial for effective treatment. We report on the case of a 79-year-old patient with a PAF who was admitted for hematochezia and melena. The PAF was suspected during upper gastrointestinal endoscopy and confirmed by CT angiography.

    The impact of upper endoscopy in patients with upper gastrointestinal hemorrhage treated in community practice is unknown. Thus we examined the effectiveness of endoscopy performed within 24 hours of admission (early endoscopy). Medical records of 909 consecutive hospitalized patients with upper gastrointestinal hemorrhage who underwent endoscopy at 13 hospitals in a large metropolitan area were reviewed. We evaluated unadjusted and severity-adjusted associations of early endoscopy with recurrent bleeding or surgery to control hemorrhage, length of hospital stay, and associations of endoscopic therapy in patients with bleeding ulcers or varices. Early endoscopy was performed in 64% of patients and compared with delayed endoscopy and was associated with clinically significant reductions in adjusted risk of recurrent bleeding or surgery (odds ratio [OR] 0.70: 95% CI [0.44, 1.13]) and a 31% decrease in adjusted length of stay (95% CI: [24%, 37%]). In patients at high risk for recurrent bleeding, the use of early endoscopic therapy to control hemorrhage was associated with reductions in recurrent bleeding or surgery (OR 0.21: 95% CI [0.10, 0.47]) and length of stay (-31%: 95% CI [-44%, -14%). In this study of community-based practice, the routine use of endoscopy, and in selected cases endoscopic therapy, performed early in the clinical course of patients with upper gastrointestinal hemorrhage was associated with reductions in length of stay and, possibly, the risk of recurrent bleeding and surgery.

    In patients with acute upper gastrointestinal hemorrhage, standard practice is to transfuse packed red blood cells, often to an arbitrary level of hemoglobin or hematocrit (typically 10 g/dL and 30%, respectively) before endoscopy. Therefore, we aimed to determine first whether performing endoscopy in patients with upper gastrointestinal hemorrhage and a low hematocrit is safe and whether it predicts outcomes. This cohort study included patients with carefully defined upper gastrointestinal hemorrhage captured in our gastrointestinal Healthcare Registry who underwent esophagogastroduodenoscopy. Patients were placed into 2 groups: low hematocrit (<30%) or high hematocrit (>30%). Clinical variables and outcomes, including cardiovascular events, intensive care unit transfer, and death, were measured. A total of 920 patients meeting entry criteria were identified. Baseline features among those with a low and high hematocrit were identical. Eight cardiovascular events occurred during or after esophagogastroduodenoscopy, including 5 of 587 (1%) in the less than 30% hematocrit group and 3 of 333 (1%) in the greater than 30% hematocrit group (P=.29). Blood transfusions were more common in the low hematocrit group (74% vs 24%, P<.001). However, correlation between the amount of blood transfused and hematocrit level was poor, and the number units of blood transfused was highly variable. There was no significant mortality difference in the 2 hematocrit groups. Most patients with upper gastrointestinal hemorrhage presented with a hematocrit less than 30%. Performing endoscopy in patients with a low hematocrit was clearly safe; these data strongly imply that waiting for the hematocrit to reach a certain level before endoscopy is not necessary.

    Gastrointestinal hemorrhage due to splenic artery aneurysm pancreatic duct fistula in chronic pancreatitis is rare. It is, however, important to diagnose this condition particularly in patients having chronic pancreatitis, since it may result in a life-threatening situation. The diagnosis is usually difficult to establish and it may take repeated admissions for intermittent gastrointestinal bleeding until the real source is recognized. Clinical attacks of epigastric pain followed by GI-bleeding 30–40 minutes later are characteristic. Occasionally these attacks are followed by transient jaundice. The present case report describes this rare complication and reviews the current literature. PMID:8268107

    Gastrointestinal complications after open-heart surgery are rare. Many preoperative, intraoperative, and postoperative factors may predispose patients to these complications or cause them. Our patient was a 64-year-old woman who underwent aortic valve replacement due to aortic stenosis. Free intra-abdominal hemorrhage occurred on the 2nd postoperative day. During exploratory laparotomy, it was determined that the hemorrhage was from a vein near the falciform ligament of the liver and from a bleeding laceration of the splenic capsule. The complication was repaired surgically. To our knowledge, intra-abdominal hemorrhage of both liver and spleen after open-heart surgery has never been reported before, even in large patient series. We report the case and present our ideas regarding the cause of the bleeding.

    Capsule endoscopy may play a role in the evaluation of patients presenting with acute upper gastrointestinal hemorrhage in the emergency department. We evaluated adults with acute upper gastrointestinal hemorrhage presenting to the emergency departments of two academic centers. Patients ingested a wireless video capsule, which was followed immediately by a nasogastric tube aspiration and later by esophagogastroduodenoscopy (EGD). We compared capsule endoscopy with nasogastric tube aspiration for determination of the presence of blood, and with EGD for discrimination of the source of bleeding, identification of peptic/inflammatory lesions, safety, and patient satisfaction. The study enrolled 49 patients (32 men, 17 women; mean age 58.3 ± 19 years), but three patients did not complete the capsule endoscopy and five were intolerant of the nasogastric tube. Blood was detected in the upper gastrointestinal tract significantly more often by capsule endoscopy (15 /18 [83.3 %]) than by nasogastric tube aspiration (6 /18 [33.3 %]; P = 0.035). There was no significant difference in the identification of peptic/inflammatory lesions between capsule endoscopy (27 /40 [67.5 %]) and EGD (35 /40 [87.5 %]; P = 0.10, OR 0.39 95 %CI 0.11 - 1.15). Capsule endoscopy reached the duodenum in 45 /46 patients (98 %). One patient (2.2 %) had self-limited shortness of breath and one (2.2 %) had coughing on capsule ingestion. In an emergency department setting, capsule endoscopy appears feasible and safe in people presenting with acute upper gastrointestinal hemorrhage. Capsule endoscopy identifies gross blood in the upper gastrointestinal tract, including the duodenum, significantly more often than nasogastric tube aspiration and identifies inflammatory lesions, as well as EGD. Capsule endoscopy may facilitate patient triage and earlier endoscopy, but should not be considered a substitute for EGD. © Georg Thieme Verlag KG Stuttgart · New York.

    Juvenile polyposis syndrome is an uncommon hamartomatous disorder with gastrointestinal (GI) manifestations of varying degree and malignant potential. We report the cases of an 8-year-old girl and a 5-year-old girl who suffered massive lower GI hemorrhage. Neither patient had a family history of polyposis. After the patients were stabilized, radiological evaluation, laparotomy, and intraoperative colonoscopy revealed multiple polyps in the colon. Both patients underwent total colectomy, mucosal proctectomy, and ileoanal anastomosis. The diagnosis of nonfamilial juvenile polyposis was based on the histological findings and the absence of a family history. To our knowledge, this presentation of juvenile polyposis has been reported only twice before. We discuss the clinical features and diagnosis of juvenile polyposis and the treatment options. Although juvenile polyposis is a rare condition in children, it should be considered in the differential diagnosis of life-threatening GI hemorrhage.

    Dyskeratosis congenita (DC) is a rare inherited disease in which the telomere complex cannot be maintained. Shortened telomeres can cause a number of clinical conditions. We herein report a case of unrelated bone marrow transplantation due to aplastic anemia associated with DC. The patient died of uncontrollable refractory intestinal bleeding. Three cases of DC with life-threatening hemorrhaging after transplantation have been reported; however, the bleeding origin could not be determined. Our case is the only patient in which a gastrointestinal bleeding point, jejunal multiple angioectasia, was determined.

    Behcet’s disease (BD) is a rare and life-long disorder characterized by inflammation of blood vessels throughout the body. BD was originally described in 1937 as a syndrome involving oral and genital ulceration in addition to ocular inflammation. Intestinal BD refers to colonic ulcerative lesions documented by objective measures in patients with BD. Many studies have shown that over 40% of BD patients have gastrointestinal complaints. Symptoms include abdominal pain, diarrhea, nausea, anorexia and abdominal distension. Although gastrointestinal symptoms are common, the demonstration of gastrointestinal ulcers is rare. This so-called intestinal BD accounts for approximately 1% of cases. There is no specific test for BD, and the diagnosis is based on clinical criteria. The manifestations of intestinal BD are similar to those of other colitis conditions such as Crohn’s disease or intestinal tuberculosis, thus, it is challenging for gastroenterologists to accurately diagnose intestinal BD in patients with ileo-colonic ulcers. However, giant ulcers distributed in the esophagus and ileocecal junction with gastrointestinal hemorrhage are rare in intestinal BD. Here, we present a case of untypical intestinal BD. The patient had recurrent aphthous ulceration of the oral mucosa, and esophageal and ileo-colonic ulceration, but no typical extra-intestinal symptoms. During examination, the patient had massive acute lower gastrointestinal bleeding. The patient underwent ileostomy after an emergency right hemicolectomy and partial ileectomy, and was subsequently diagnosed with incomplete-type intestinal BD by pathology. The literature on the evaluation and management of this condition is reviewed. PMID:24527178

  12. Two forensic autopsy cases of death due to upper gastrointestinal hemorrhage: a comparison of postmortem computed tomography and autopsy findings.

    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.

    Nonvariceal upper gastrointestinal (UGI) bleeding recurs after appropriate endoscopic therapy in 10 % - 15 % of cases. The mortality rate can be as high as 25 % when bleeding recurs, but there is no consensus about the best modality for endoscopic re-treatment. The aim of this study was to evaluate clipping and detachable snaring (CDS) for rescue endoscopic control of nonvariceal UGI hemorrhage. We report a case series of seven patients from a Korean tertiary center who underwent endoscopic hemostasis using the combined method of detachable snares with hemoclips. The success rate of endoscopic hemostasis with CDS was 86 %: six of the seven patients who had experienced primary endoscopic treatment failure or recurrent bleeding after endoscopic hemostasis were treated successfully. In conclusion, rescue endoscopic bleeding control by means of CDS is an option for controlling nonvariceal UGI bleeding when no other method of endoscopic treatment for recurrent bleeding and primary hemostatic failure is possible. © Georg Thieme Verlag KG Stuttgart · New York.

    Pseudoxantoma elasticum is a rare, hereditary, multisystemic disease affecting the skin, eye, and cardiovascular system. A twenty-eight-year-old female has presented to emergency unit with the complaint of gastrointestinal hemorrhage. This patient, who had been monitored in the gastroenterology clinic more than 10 times in the past 8 years, noted a repetitive hemorrhage during her previous pregnancy in her history. The examination of the patient revealed the following signs and symptoms: atrophy in the epithelium of the retina pigment; typical angioid streaks and peau d'orange finding in the fundus; thinning of the retinal nerve fiber in OCT (optic coherence tomography); bilateral and reticular papillary lesions with yellowish-color in the neck region (plucked chicken appearance); presence of bleeding foci in fundus; and nephrocalcinosis in kidneys. In light of these symptoms, the patient was diagnosed with pseudoxantoma elasticum. Skin biopsy confirmed the pseudoxantoma elasticum diagnose. PXE is an uncommon, hereditary disease. Early diagnosis of pseudoxantoma elasticum cases, is important for minimalizing systemic complications and informing the other family members through genetic counseling. PMID:17657851

    We applied multivariate analysis to the clinical findings in patients with acute gastrointestinal (GI) hemorrhage and compared the relationship between these findings and angiographic evidence of extravasation. Our study population consisted of 46 patients with acute GI bleeding. They were divided into two groups. In group 1 we retrospectively analyzed 41 angiograms obtained in 29 patients (age range, 25-91 years; average, 71 years). Their clinical findings including the shock index (SI), diastolic blood pressure, hemoglobin, platelet counts, and age, which were quantitatively analyzed. In group 2, consisting of 17 patients (age range, 21-78 years; average, 60 years), we prospectively applied statistical analysis by a logistics regression model to their clinical findings and then assessed 21 angiograms obtained in these patients to determine whether our model was useful for predicting the presence of angiographic evidence of extravasation. On 18 of 41 (43.9%) angiograms in group 1 there was evidence of extravasation; in 3 patients it was demonstrated only by selective angiography. Factors significantly associated with angiographic visualization of extravasation were the SI and patient age. For differentiation between cases with and cases without angiographic evidence of extravasation, the maximum cutoff point was between 0.51 and 0.0.53. Of the 21 angiograms obtained in group 2, 13 (61.9%) showed evidence of extravasation; in 1 patient it was demonstrated only on selective angiograms. We found that in 90% of the cases, the prospective application of our model correctly predicted the angiographically confirmed presence or absence of extravasation. We conclude that in patients with GI hemorrhage, angiographic visualization of extravasation is associated with the pre-embolization SI. Patients with a high SI value should undergo study to facilitate optimal treatment planning.

    Hepatocellular carcinoma (HCC) rarely invades the gastrointestinal (GI) tract. It occurs in 0.7% to 2% of clinical HCC cases. Moreover, gastric invasion with GI hemorrhage via peritoneal seeding is very rare. We report the case of 67-year-old woman who had a history of HCC rupture and was admitted due to left upper quadrant abdominal pain. The patient was diagnosed with three omental metastatic masses and underwent hepatic segmentectomy and omental tumorectomy. Two months later, the patient had massive melena, and an esophagogastroduodenoscopy showed very large ulcerated friable mass on the gastric body. The histology was consistent with the diagnosis of metastatic HCC. The patient died from persistent GI hemorrhage 93 days after the admission. This case illustrates the very rare event of peritoneal seeding of a ruptured HCC causing direct invasion of the stomach, followed by GI hemorrhage.

    H2-antagonists are frequently used in the management of upper gastrointestinal (UGI) hemorrhage despite their lack of proven efficacy. In order to determine the pattern of H2-antagonist usage for this indication, we retrospectively reviewed the charts of 137 patients admitted with acute UGI bleeding over a 1-year period at two teaching hospitals in West Texas. An H2-antagonist was ordered in 89% of patients (77%) intravenous, 12% oral). It was administered within 2 h of admission in 25% of these patients, within 4 h in 54%, and within 8 h in 78%. An H2-antagonist was ordered among the initial six orders in 49% and among the initial 10 orders in 77% of patients. Considering orders for specific therapies, an H2-antagonist was in the initial three orders in 60% of patients and among the initial six orders in 97%. Of the patients who were prescribed an H2-antagonist and who also had upper endoscopy, the drug was ordered prior to endoscopy in 86%. This review of H2-antagonist usage in the management of acute UGI bleeding has identified a prescribing pattern of writing for these drugs early in the sequence of order writing, with the drugs being given early in the course of hospitalization.

    AIM: To describe the prevalence, diagnosis, treatment, and outcomes of end stage liver disease (ESLD) patients with severe epistaxis thought to be severe upper gastrointestinal hemorrhage (UGIH). METHODS: This observational single center study included all consecutive patients with ESLD and epistaxis identified from consecutive subjects hospitalized with suspected UGIH and prospectively enrolled in our databases of severe UGIH between 1998 and 2011. RESULTS: A total of 1249 patients were registered for severe UGIH in the data basis, 461 (36.9%) were cirrhotics. Epistaxis rather than UGIH was the bleeding source in 20 patients. All patients had severe coagulopathy. Epistaxis was initially controlled in all cases. Fifteen (75%) subjects required posterior nasal packing and 2 (10%) embolization in addition to correction of coagulopathy. Five (25%) patients died in the hospital, 12 (60%) received orthotopic liver transplantation (OLT), and 3 (15%) were discharged without OLT. The mortality rate was 63% in patients without OLT. CONCLUSION: Severe epistaxis in patients with ESLD is (1) a diagnosis of exclusion that requires upper endoscopy to exclude severe UGIH; and (2) associated with a high mortality rate in patients not receiving OLT.

    Few prospective data are currently available on acute gastrointestinal hemorrhage (AGIH) as a complication of acute renal failure (ARF). The aim of the present study was to define incidence, sources, risk factors, and outcome of AGIH in patients with ARF. We performed a prospective study on an inception cohort of 514 patients admitted for ARF to a nephrology intermediate care unit. Data on clinical risk factors for bleeding, frequency of occurrence of AGIH, length of hospital stay, and in-hospital mortality were collected. Independent predictors of AGIH were identified. The relative odds of death and the relative increase in length of hospital stay associated with AGIH were calculated after adjusting for baseline comorbidities. Sixty-nine patients out of 514 [13.4% (95% CI, 10.6 to 16.7)] had AGIH as a complication of ARF; 59 were upper AGIH. Forty patients had clinically important bleeding. Erosions and/or ulcers accounted for 71% of cases of upper AGIH. Independent baseline predictors of AGIH were represented by severity of illness [odds ratio 1.45 (95% CI, 1.05 to 2.01) for every 10 point increase in APACHE II score], low platelet count [<50,000 mm3; 3.71 (1.70 to 8.11)], noncirrhotic chronic hepatic disease [2.22 (1.09 to 4.55)], liver cirrhosis [3.38 (1.50 to 7.60)], de novo ARF [2.77 (1.30 to 5.90)], and severe ARF [2.07 (1.10 to 3.88)]. In-hospital mortality was 63.8% in patients with AGIH and 34.2% in the other patients; after adjusting for baseline confounders, AGIH remained significantly associated with an increase in both mortality [2.57 (1.30 to 5.09), P = 0.006] and length of hospital stay [37% (1 to 87%), P = 0.047]. AGIH and clinically important bleeding are frequent complications of ARF. In this clinical condition, AGIH is more often due to upper gastrointestinal bleeding and is associated with a significantly increased risk of death and length of hospital stay. Both renal and extrarenal risk factors are related to the occurrence of AGIH.

    The purpose of this study was to identify endoscopic and clinical parameters influencing the decision-making in salvage of endoscopically unmanageable, nonvariceal upper gastrointestinal hemorrhage (UGIH) and to report the outcome of selected therapy. We retrospectively retrieved all cases of surgery and arteriography for arrest of endoscopically unmanageable UGIH. Only patients with overt bleeding on endoscopy within the previous 24 h were included. Patients with preceding nonendoscopic hemostatic interventions, portal hypertension, malignancy, and transpapillar bleeding were excluded. Potential clinical and endoscopic predictors of allocation to either surgery or arteriography were tested using statistical models. Outcome and survival were regressed on the choice of rescue and clinical variables. Forty-six arteriographed and 51 operated patients met the inclusion criteria. Univariate analysis revealed a higher number of patients with a coagulation disorder in the catheterization group (41.4%, versus 20.4% in the laparotomy group; p = 0.044). With multivariate analysis, the identification of a bleeding peptic ulcer at endoscopy significantly steered decision-making toward surgical rescue (OR = 5.2; p = 0.021). Taking into account reinterventions, hemostasis was achieved in nearly 90% of cases in both groups. Overall therapy failure (no survivors), rebleeding within 3 days (OR = 3.7; p = 0.042), and corticosteroid use (OR = 5.2; p = 0.017) had a significant negative impact on survival. The odds of dying were not different for embolotherapy or surgery. In conclusion, decision-making was endoscopy-based, with bleeding peptic ulcer significantly directing the choice of rescue toward surgery. Unsuccessful hemostasis and corticosteroid use, but not the choice of rescue, negatively affected outcome.

    From an Italian Registry of patients with upper gastrointestinal hemorrhage (UGIH), we assessed the clinical outcomes and explored the roles of clinical, endoscopic, and therapeutic factors on 30-day mortality in a real life setting. Prospective analysis of consecutive patients endoscoped for UGIH at 23 community and tertiary care institutions from 2003 to 2004. Covariates and outcomes were defined a priori and 30-day follow-up obtained. Logistic regression analysis identified predictors of mortality. One thousand and twenty patients were included. A total of 46 patients died for an overall 4.5% mortality rate. In all, 85% of deaths were associated with one or more major comorbidity. Sixteen of 46 patients (35%) died within the first 24 h of the onset of bleeding. Of these, eight had been categorized as ASA class 1 or 2 and none of them was operated upon, despite a failure of endoscopic intention to treatment in four. Regression analysis showed advanced age, presence of severe comorbidity, low hemoglobin levels at presentation, and worsening health status as the only independent predictors of 30-day mortality (P < 0.001). The acute use of a PPI exerted a protective effect (OR 0.23, 95% CI 0.09-0.73). Recurrent bleeding was low (3.2%). Rebleeders accounted for only 11% of the total patients deceased (OR 3.27, 95% CI 1.5-11.2). These results indicate that 30-day mortality for nonvariceal bleeding is low. Deaths occurred predominantly in elderly patients with severe comorbidities or those with failure of endoscopic intention to treatment.

    Background/Aim: Acute upper gastrointestinal hemorrhage (AUGIH) is a life-threatening emergency that results in high morbidity and mortality. The mortality rate varies between 4% and 14%. The aim of the study was to determine the clinical outcome of AUGIH among patients admitted to a government hospital in Egypt. Patients and Methods: This was a cross-sectional hospital-based study performed in 1000 patients presenting with AUGIH over a 7-year period between January 2004 and January 2011. Results: One thousand patients were analyzed. Fifty-four percent were male. Mean age was 52 ± 17 years. Eighty-eight percent were emergency admissions and 12% were inpatients at the time of bleeding. At presentation 68% had major comorbidity and 50% had liver disease. Seven hundred and twenty-four patients (72%) underwent endoscopy. Bleeding varices accounted for 31% of AUGIH and peptic ulcer 28%. Two hundred and thirty-two patients had endoscopically diagnosed bleeding varices or peptic ulcer with a visible vessel or active bleeding. These received endoscopic therapy. Initial hemostasis was achieved in 207 (89%). Thirteen patients (6%) had therapy at a subsequent endoscopy for further bleeding. Surgery was performed on 9 patients (0.9%) with AUGIH. Complications were reported in 70 patients (7%) mainly liver failure (4%). Six hundred and eighty-four patients (68%) were discharged improved, 162 (16%) left hospital without a diagnosis and 4 (0.4%) were referred to another facility. The overall mortality was 15%. Mortality was 24% in patients ≥60 years, 37% among inpatients, and 21% in those who had a major comorbidity. Mortality was 22% in patients who had liver disease and 9% in variceal bleeding. Conclusion: The most common cause of AUGIH was variceal in origin. Endoscopic therapy was successful in most cases. Mortality after AUGIH was particularly high among elderly patients, inpatients, and patients who had a major comorbidity, liver disease, and variceal bleeding. PMID

    Purpose: To determine whether transcatheter arterial embolization performed in the setting of active gastric or duodenal nonvariceal hemorrhage is efficacious when the bleeding source cannot be identified angiographically. Methods: Records of 115 adult patients who underwent visceral angiography for endoscopically documented gastric (50 patients) or duodenal (65 patients) nonvariceal hemorrhage were retrospectively reviewed. Patients were subdivided into three groups according to whether angiographic evidence of arterial hemorrhage was present and whether embolization was performed (group 1 = no abnormality, no embolization; group 2 = no abnormality, embolization performed [empiric embolization]; and group 3 = abnormality present, embolization performed). Thirty-day rates and duration of primary hemostasis and survival were compared.ResultsFor patients with gastric sources of hemorrhage, the rate of primary hemostasis at 30 days after embolization was greater when embolization was performed in the setting of a documented angiographic abnormality than when empiric embolization was performed (67% vs. 42%). The rate of primary hemostasis at 30 days after angiography was greater for patients with duodenal bleeding who either underwent empiric embolization (60%) or embolization in the setting of angiographically documented arterial hemorrhage (58%) compared with patients who only underwent diagnostic angiogram (33%). Patients with duodenal hemorrhage who underwent embolization were less likely to require additional invasive procedures to control rebleeding (p = 0.006). Conclusion: Empiric arterial embolization may be advantageous in patients with a duodenal source of hemorrhage but not in patients with gastric hemorrhage.

    Upper gastrointestinal tract hemorrhage (UGIH) is a common and potentially life-threatening disorder. Resource utilization can vary without adverse effect on patient outcome. Clinical practice guidelines are a potential solution to reduce variation in practice while improving patient outcomes. To validate prospectively the safety, acceptability, and impact of a clinical practice guideline defining the medically appropriate length of stay (LOS) for patients hospitalized with UGIH. Prospective, controlled time-series study with an alternate-month design. Outcome surveyors and patients were blinded to study group allocation. GUIDELINE: A retrospectively validated scoring system using 4 independent variables: hemodynamics, time from bleeding, comorbidity, and esophagogastroduodenoscopy (EGD) findings to predict risk of adverse events. The quantitative risk for the low-risk subset was 0.6% (95% confidence interval [CI], 0.0%-2.0%) for subsequent complications and 0% (95% CI, 0.0%-0.9%) for life-threatening complications from this retrospective evaluation. A 1000-bed, not-for-profit, university-affiliated teaching hospital. Consecutive adult patients hospitalized for acute UGIH. Concurrent feedback of guideline recommendation (same-day hospital discharge) to physicians caring for patients at low risk for complication. No risk information was provided during control months. Seventy percent (209/299) of UGIH patients achieved low-risk status according to the guideline and were therefore potentially suitable for early discharge from the hospital.

    We examined the interaction between race, insurance, and important outcomes in nonvariceal upper gastrointestinal hemorrhage (NVUGIH). Adults with NVUGIH were selected from the National Inpatient Sample. in-hospital mortality. treatment modalities [esophagogastroduodenoscopy (EGD), early EGD, and endoscopic or radiologic therapy], and resource utilization (length of hospital stay and total hospitalization charges). Mortality was similar for Medicare and private insurance [adjusted odds ratios (aOR): 1.15 95% confidence interval (CI) 0.90 to 1.47), P=0.24], but higher for under/uninsured patients [aOR: 1.84 (CI: 1.42 to 2.40), P<0.01]. Compared with Medicare, patients with private insurance had more EGDs [aOR: 1.35 (CI: 1.23 to 1.48), P<0.01], early EGDs [aOR: 1.29 (CI: 1.21 to 1.38), P<0.01], and endoscopic [aOR: 1.19 (CI: 1.11 to 1.27), P<0.01], or radiologic therapy [aOR:1.35 (CI: 1.06 to 1.71), P=0.01]. Patients who were under/uninsured had less EGDs [aOR: 0.84 (CI: 0.76 to 0.91), P<0.01] or endoscopic therapy [aOR: 0.74 (CI: 0.68 to 0.81), P<0.01], but similar odds of early EGD [aOR: 0.95 (CI: 0.88 to 1.02), P=0.13] or radiologic therapy [aOR: 1.01 (CI: 0.75 to 1.37), P=0.75]. Compared with whites, blacks had lower [aOR: 0.73 (CI: 0.58 to 0.93), P=0.01] and Native Americans higher mortality [aOR: 2.60 (CI: 1.57 to 4.13), P<0.01]. Blacks were less likely [aOR: 0.86 (CI: 0.79 to 0.94), P<0.01] and Asians more likely [aOR: 1.24 (CI: 1.05 to 1.47), P=0.01] to have EGDs. Both blacks and Hispanics had lower, whereas Asians had higher early EGD rates. Patients with private insurance had lower total charges [adjusted mean difference: -$2761 (CI: -$4617 to -$906), P<0.01]. Insurance and race have independent effects on NVUGIH mortality, therapeutic modalities used, and resource utilization. Black and under/uninsured patients have the worst outcomes.

    Although an increasing number of patients accept dual antiplatelet therapy (DAPT) following implantation of drug-eluting stents (DES) for coronary heart disease (CHD), the proportion of patients with DAPT who subsequently develop gastrointestinal hemorrhage continues to increase. To ensure the clinical outcomes from DES, it is important to formulate a novel continued antiplatelet therapy for patients who were administered DAPT and subsequently develop gastrointestinal hemorrhage following DES implantation. The present study aimed to evaluate the effects of continued aspirin, clopidogrel or DAPT use on the incidence of clinical adverse events and gastrointestinal rebleeding in patients who received DAPT and subsequently developed gastrointestinal hemorrhage following implantation of DES for CHD. Between 2004 and 2010, 108 consecutive patients receiving DAPT developed gastrointestinal hemorrhage following DES implantation for CHD at Liuzhou General Hospital (Liuzhou, Guangxi). These patients were divided into three groups according to the novel antiplatelet therapy. The occurrence of major adverse cardiac events (MACE), including cardiac death, non-fatal myocardial infarction, heart failure or target vessel revascularization, net adverse clinical events (NACE), including major bleeding, stroke or MACE, and gastrointestinal rebleeding during clinical follow-up following the initial procedure were compared among these three groups. The results of this analysis demonstrated that the occurrence rate of MACE, NECE and gastrointestinal rebleeding was not significantly different among these groups (P>0.05). Furthermore, survival analysis was performed and although the survival curves of MACE and NECE were not significantly different among these groups, gastrointestinal rebleeding was demonstrated to be significantly different among the three groups (P<0.05), and continued aspirin or clopidogrel use was superior to continued DAPT. In conclusion, the results of the present

    The aim of this study was to evaluate the usefulness of the limited fluid resuscitation regimen combined with blood pressure-controlling drugs in treating acute upper gastrointestinal hemorrhage concomitant with hemorrhagic shock. A total of 51 patients were enrolled and divided into a group that received traditional fluid resuscitation group (conventional group, 24 patients) and a limited fluid resuscitation group (study group, 27 patients). Before and after resuscitation, the blood lactate, base excess, and hemoglobin values, as well as the volume of fluid resuscitation and resuscitation time were examined. Compared with conventional group, study group had significantly better values of blood lactate, base excess, and hemoglobin (all p < 0.05). In addition, both volume of fluid resuscitation and resuscitation time were significantly (p < 0.05) lower in these patients. Limited fluid resuscitation combined with blood pressure-controlling drugs effectivelyxxx maintains blood perfusion of vital organs, improves whole body perfusion indicators, reduces the volume of fluid resuscitation, and achieves better bleeding control and resuscitation effectiveness.

    Etiology of hemorrhagic gastroenteritis (HGE) syndrome in dogs is unknown and histopathologic and microbial investigations have only been performed post mortem. To identify characteristic intra vitam endoscopic and histologic mucosal lesions, as well as bacterial species, within the mucosa of dogs with HGE. Ten dogs diagnosed with HGE were included. Eleven dogs with gastroduodenoscopy and different intestinal diseases were used as controls for microbial changes. Dogs pretreated with antibiotics or diagnosed with any disease known to cause bloody diarrhea were excluded from the study. In this prospective study, gastrointestinal biopsies were collected from 10 dogs with HGE. Endoscopic and histologic changes were assessed according to WSAVA guidelines. Biopsies from the stomach, duodenum, ileum, and colon were investigated by histology and by immunohistochemistry for the presence of Clostridium spp. and parvovirus. The first duodenal biopsy taken with a sterile forceps was submitted for bacterial culture. Acute mucosal lesions were only found in the intestines, not in the stomach. Clostridium spp., identified as Clostridium perfringens in 6/9 cases, were detected on the small intestinal mucosa in all dogs with HGE, either by culture or immunohistopathology. In the control group, C. perfringens could only be cultured in one of 11 dogs. The results of this study demonstrate an apparent association between C. perfringens and the occurrence of acute hemorrhagic diarrhea. The term "HGE," which implies the involvement of the stomach, should be renamed as "acute hemorrhagic diarrhea syndrome." Copyright © 2013 by the American College of Veterinary Internal Medicine.

    Postoperative coma is not uncommon in patients after craniotomy. It generally presents as mental state changes and is usually caused by intracranial hematoma, brain edema, or swelling. Hyperammonemia can also result in postoperative coma; however, it is rarely recognized as a potential cause in coma patients. Hyperammonemic coma is determined through a complicated differential diagnosis, and although it can also be induced as a side effect of valproate (VPA), this cause is frequently unrecognized or confused with upper gastrointestinal hemorrhage (UGH)-induced hepatic encephalopathy. We herein present a case of valproate-induced hyperammonemic encephalopathy (VHE) to illustrate the rarity of such cases and emphasize the importance of correct diagnosis and proper treatment. A 61-year-old woman with meningioma was admitted into our hospital. Radical resection of the tumor was performed, and the patient recovered well as expected. After administration of valproate for 7 days, the patient was suddenly found in a deep coma, and her mental state deteriorated rapidly. The diagnoses of hepatic encephalopathy was confirmed. However, whether it origins from upper gastrointestinal hemorrhage or valproate side effect is uncertain. The patient's condition fluctuated without improvement during the subsequent 3 days under the treatment of reducing ammonia. With the discontinuation of valproate treatment, the patient regained complete consciousness within 48 hours, and her blood ammonia decreased to the normal range within 4 days. VHE is a rare but serious complication in patients after craniotomy and is diagnosed by mental state changes and elevated blood ammonia. Thus, the regular perioperative administration of VPA, which is frequently neglected as a cause of VHE, should be emphasized. In addition, excluding UGH prior to providing a diagnosis and immediately discontinuing VPA administration are recommended.

    Aberrant right subclavian artery-esophageal fistula is a rare but potentially fatal complication. It may be associated with procedures, such as tracheostomy and tracheal or esophageal intubation, and yields massive upper gastrointestinal bleeding difficult to identify and to control. A high index of suspicion is essential for early diagnosis and better prognosis. We report a rare case of a patient who survived after emergent surgical procedure for massive upper gastrointestinal bleeding secondary to aberrant right subclavian artery-esophageal fistula after prolonged intubation.

    A primary aortoduodenal fistula (PADF) is a rare cause of gastrointestinal bleeding that is difficult to diagnose (and sometimes not diagnosed until a laparotomy.) A PADF is associated with high mortality if undiagnosed and untreated (the mortality rate of nearly 100% in the absence of a surgical intervention). While this condition is extremely rare with an incidence rate at autopsy of 0.04% to 0.07%, a secondary ADF occurs much more commonly (the post-operative incidence of 0.5% to 2.3%) and is due to prior aortic surgery and/or the placement of a synthetic aortic graft. It should be considered in any elderly patient who presents with upper gastrointestinal bleeding in the context of a known abdominal aortic aneurysm or without it when no identifiable source of bleeding is found. We present an autopsy case of a 59-year-old man with no history of an abdominal aortic aneurysm who presented with intermittent massive gastrointestinal bleeding. The autopsy revealed a pinhole fistula. It was identified between an atherosclerotic abdominal aortic aneurysm and the lower horizontal part of the duodenum. Our case indicates that the aortoenteric fistula can result in fatal gastrointestinal bleeding. This case is unique in that the fistula formed as a result of a complex atherosclerotic abdominal aorta and a localized necrotizing granulomatous aortitis the etiology of which was not clear.

    Mucormycosis is an invasive and aggressive opportunistic fungal infection that usually presents with rhinocerebral or pulmonary involvement and rarely involves the gastrointestinal tract. The disease is acute with mortality rate up to 100%. A 68-year-old male was undergoing treatment at a local hospital for COPD exacerbation with IV steroids and antibiotics. Two weeks into his treatment he suddenly developed massive upper GI bleeding and hemodynamic instability that necessitated transfer to our tertiary care hospital for further treatment and management. An urgent upper endoscopy revealed multiple large and deep gastric and duodenal bulb ulcers with stigmata of recent bleeding. The ulcers were treated endoscopically. Biopsies showed fibrinopurulent debris with fungal organisms. Stains highlighted slightly irregular hyphae with rare septa and yeast suspicious for Candida. The patient was subsequently placed on fluconazole. Unfortunately, the patient’s general condition continued to worsen and he developed multiorgan failure and died. Autopsy revealed disseminated systemic mucormycosis. Most of the cases of gastrointestinal mucormycosis were reported from the tropics and few were reported in the United States. The disease occurs most frequently in immunocompromised individuals. The rare incidence of GI involvement, acute nature, severity and the problematic identification of the organisms on biopsies make antemortem diagnosis challenging. Treatment includes parenteral antifungals and debridement of the infected tissues. Gastroenterologists should be aware of this rare cause of gastrointestinal bleeding and understand the importance of communication with the reviewing pathologist so that appropriate, and often lifesaving, therapies can be administered in a timely manner.

    Here, we report a case of a young man who presented with a significant upper gastrointestinal bleed treated by endoscopic removal of multiple hyperplastic polyps. Gastric hyperplastic polyps are a relatively uncommon cause of overt gastrointestinal bleeding. While most hyperplastic gastric polyps are asymptomatic, they may present with abdominal pain, iron deficiency anemia or gastric outlet obstruction. These polyps are associated with conditions such as Helicobacter pylori gastritis and atrophic autoimmune gastritis, which predispose the epithelium to chronic inflammation and epithelial repair. The patient presented to Northwestern Memorial Hospital in July 2011. The polyps were resected by clip-assisted snare polypectomy. Histopathologic assessment of the resected polyps demonstrated multiple, non-ulcerative hyperplastic polyps measuring 1.3-1.8 cm in size, without evidence of dysplasia or malignancy. This case describes a young adult patient with multiple, large gastric polyps causing overt gastrointestinal bleeding. This is a rare presentation in a young individual, as these polyps are typically identified in patients older than 60 years of age and less commonly, pediatric populations.

    To determine the prevalence of hemorrhagic gastro-intestinal (GI) disease developing in dogs and cats admitted for management of non-GI disease in veterinary intensive care units (ICUs). Retrospective study of animals presented between October 2012 and July 2013. Three ICUs located in veterinary teaching hospitals in the United Kingdom. Dogs (n = 272) and cats (n = 94) were consecutively enrolled from 3 ICUs if they were hospitalized in the unit for at least 24 hours. Cases were excluded if they had hemorrhagic GI disease in the 48-hour period before presentation or in the 24-hour period after admission. Cases were also excluded if they suffered skull fracture, epistaxis, or hemoptysis, if they underwent surgical procedures of the GI or upper respiratory tracts, or if they were presented for management of GI disease. Hemorrhagic GI disease was observed in dogs at all 3 units, but at different rates (Center 1: 10.3%, Center 2: 4.8%, Center 3: 2.2%). Hemorrhagic GI disease was not observed in cats at any of the participating centers. Construction of a multivariable logistic regression model revealed that serum albumin concentration, administration of prophylactic gastro-protectant drugs, and institution were significantly associated with the development of hemorrhagic GI disease in dogs. Development of hemorrhagic GI disease and placement of a feeding tube were significantly associated with mortality during the period of hospitalization in dogs. Thirty-seven (13.6%) dogs and 12 (12.8%) cats died or were euthanized while hospitalized, with a higher mortality rate (42.1%) in dogs with hemorrhagic GI disease. Hemorrhagic GI disease does develop in dogs hospitalized for management of non-GI disease, but this phenomenon was not observed in cats. Development of hemorrhagic GI disease appeared to have a significant impact on survival in veterinary ICUs. © Veterinary Emergency and Critical Care Society 2015.

    Acute nonvariceal upper gastrointestinal (UGI) hemorrhage is a frequent complication associated with significant morbidity and mortality. The most common cause of UGI bleeding is peptic ulcer disease, but the differential diagnosis is diverse and includes tumors; ischemia; gastritis; arteriovenous malformations, such as Dieulafoy lesions; Mallory-Weiss tears; trauma; and iatrogenic causes. Aggressive treatment with early endoscopic hemostasis is essential for a favorable outcome. However, severe bleeding despite conservative medical treatment or endoscopic intervention occurs in 5-10% of patients, requiring surgery or transcatheter arterial embolization. Surgical intervention is usually an expeditious and gratifying endeavor, but it can be associated with high operative mortality rates. Endovascular management using superselective catheterization of the culprit vessel, < sandwich> occlusion, or blind embolization has emerged as an alternative to emergent operative intervention for high-risk patients and is now considered the first-line therapy for massive UGI bleeding refractory to endoscopic treatment. Indeed, many published studies have confirmed the feasibility of this approach and its high technical and clinical success rates, which range from 69 to 100% and from 63 to 97%, respectively, even if the choice of the best embolic agent among coils, cyanaocrylate glue, gelatin sponge, or calibrated particles remains a matter of debate. However, factors influencing clinical outcome, especially predictors of early rebleeding, are poorly understood, and few studies have addressed this issue. This review of the literature will attempt to define the role of embolotherapy for acute nonvariceal UGI hemorrhage that fails to respond to endoscopic hemostasis and to summarize data on factors predicting angiographic and embolization failure.

    Background and study aims Cameron ulcers are a rare but clinically significant cause of severe upper gastrointestinal hemorrhage (SUGIH). Our aims were to describe (1) the diagnosis, treatment and outcomes of patients with Cameron ulcers causing hospitalization for SUGIH, (2) the differences between patients with occult vs. overt bleeding and (3) between patients treated surgically and medically. Patients and methods Over the past 17 years, all consecutive patients hospitalized in our two tertiary referral medical centers for severe UGIH or severe obscure GIH and entered into our large prospective databasis were screened for Cameron ulcer diagnosis. Results Cameron ulcers were diagnosed in 25 patients of 3960 patients with SUGIH (0.6%). 21 patients had follow-up (median [IQR] time of 20.4 months [8.5–31.8]). Patients were more often elderly females with chronic anemia, always had large hiatal hernias, and were usually referred for obscure SUGIH. Twelve (57.2%) patients were referred to surgery for rebleeding and recurrent blood loss while treated with high dose of proton pump inhibitors (PPI). 9 (42.8%) other patients continued PPI without any rebleeding during the follow-up. Patients with overt bleeding had significantly more prior hospitalizations for SUGIH, more often stigmata of hemorrhage on ulcers, and more red blood cell transfusions than patients with occult bleeding. However, there was no difference in rebleeding and mortality rates between the two groups. Conclusions Cameron ulcers in large hiatal hernias are an uncommon cause of SUGIH. Most of patients are referred for obscure GIH. The choice of medical vs. surgical therapy should be individualized. PMID:23616128

    Active but intermittent gastrointestinal (GI) bleeding can be readily detected with dynamic planar scintigraphic imaging. This is a case of a 48-year-old woman who presented from an outside institution with active GI bleeding on 99mTc-labeled RBC (99mTc-RBC) scintigraphy, but the upper and lower GI evaluations failed to subsequently localize the site of persistent bleeding. Repeat 99mTc-RBC planar scintigraphy identified a focus of active extravasation in the right lower quadrant of the abdomen. Dynamic SPECT/CT imaging was immediately performed and further identified the ileocecal valve region as the precise site of active extravasation, which was confirmed at surgery.

    Background/Aims To evaluate the ability of the recently proposed albumin, international normalized ratio (INR), mental status, systolic blood pressure, age >65 years (AIMS65) score to predict mortality in patients with acute upper gastrointestinal bleeding (UGIB). Methods AIMS65 scores were calculated in 251 consecutive patients presenting with acute UGIB by allotting 1 point each for albumin level <30 g/L, INR >1.5, alteration in mental status, systolic blood pressure ≤90 mm Hg, and age ≥65 years. Risk stratification was done during the initial 12 hours of hospital admission. Results Intensive care unit (ICU) admission, endoscopic therapy, or surgery were required in 51 patients (20.3%), 64 (25.5%), and 12 (4.8%), respectively. The predictive accuracy of AIMS65 scores ≥2 was high for blood transfusion (area under the receiver operator characteristic curve [AUROC], 0.59), ICU admission (AUROC, 0.61), and mortality (AUROC, 0.74). The overall mortality was 10.3% (n=26), and was 3%, 7.8%, 20%, 36%, and 40% for AIMS65 scores of 0, 1, 2, 3, and 4, respectively; these values were significantly higher in those with scores ≥2 (30.9%) than in those with scores <2 (4.5%, p<0.001). Conclusions AIMS65 is a simple, accurate, non-endoscopic risk score that can be applied early (within 12 hours of hospital admission) in patients with acute UGIB. AIMS65 scores ≥2 predict high in-hospital mortality. PMID:26473120

    The smaller volemic state from hypertonic (7.5%) saline (HS) solution administration in hemorrhagic shock can determine lesser systemic oxygen delivery and tissue oxygenation than conventional plasma expanders. In a model of hemorrhagic shock in dogs, we studied the systemic and gastrointestinal oxygenation effects of HS and hyperoncotic (6%) dextran-70 in combination with HS (HSD) solutions in comparison with lactated Ringer's (LR) and (6%) hydroxyethyl starch (HES) solutions. Forty-eight mongrel dogs were anesthetized, mechanically ventilated, and subjected to splenectomy. A gastric air tonometer was placed in the stomach for intramucosal gastric CO(2) (Pgco(2)) determination and for the calculation of intramucosal pH (pHi): The dogs were hemorrhaged (42% of blood volume) to hold mean arterial blood pressure at 40-50 mm Hg over 30 min and were then resuscitated with LR (n = 12) in a 3:1 relation to removed blood volume; HS (n = 12), 6 mL/kg; HSD (n = 12), 6 mL/kg; and HES (mean molecular weight, 200 kDa; degree of substitution, 0.5) (n = 12) in a 1:1 relation to the removed blood volume. Hemodynamic, systemic, and gastric oxygenation variables were measured at baseline, after 30 min of hemorrhage, and 5, 60, and 120 min after intravascular fluid resuscitation. After fluid resuscitation, HS showed significantly lower arterial pH and mixed venous Po(2) and higher systemic oxygen uptake index and systemic oxygenation extraction than LR and HES (P < 0.05), whereas HSD showed significantly lower arterial pH than LR and HES (P < 0.05). Only HS and HSD did not return arterial pH and pHi to control levels (P < 0.05). In conclusion, all solutions improved systemic and gastrointestinal oxygenation after hemorrhagic shock in dogs. However, the HS solution showed the worst response in comparison to LR and HES solutions in relation to systemic oxygenation, whereas HSD showed intermediate values. HS and HSD solutions did not return regional oxygenation to control values.

    Purpose: To evaluate the efficacy and safety of subselective arterial embolization with polyvinyl alcohol (PVA) particles with or without microcoil augmentation to control postoperative lower gastrointestinal (GI) bleeding. Methods: Ten patients with clinical, scintigraphic, and angiographic evidence of postoperative lower GI bleeding were considered for subselective embolization. Subselective embolizations were performed through coaxial microcatheters with 355-500 {mu}m PVA particles with or without additional coil embolization. Results: Embolization was technically successful in 9 of 10 (90%) patients. In one patient, subselective embolization was not possible; consequently no embolization was performed. Clinical success was achieved after a single embolization in 6 of 10 (60%) patients and after a second embolization in an additional 3 of the 10 (30%) patients. While there was no rebleeding in patients with normal coagulation parameters, all three patients (100%) with coagulopathy rebled, two of them from another source. Although no acute ischemic effects developed, no long-term sequela such as ischemic stricture were specifically looked for. Seven patients developed abdominal discomfort and/or fever within 24-48 hr. Four of 10 patients died of complications other than hemorrhage or ischemia. Conclusion: Subselective PVA embolization with or without a microcoil embolization is an effective and safe means of managing postoperative lower GI hemorrhage in patients with multiorgan trauma.

    Acute upper gastrointestinal (GI) hemorrhage is a common presentation in hospital-based emergency departments (EDs). A novel diagnostic approach is to use video capsule endoscopy to directly visualize the upper GI tract and identify bleeding. Our objective was to evaluate and compare the relative costs and benefits of video capsule endoscopy compared to other strategies in low- to moderate-risk ED patients with acute upper GI hemorrhage. We constructed a model using standard decision analysis software to examine the cost-effectiveness of 4 available strategies for a base-case patient who presents to the ED with either mild- or moderate-risk scenarios (by Glasgow-Blatchford Score) for requiring invasive hemostatic intervention (ie, endoscopic, surgical, etc) The 4 available diagnostic strategies were (1) direct imaging with video capsule endoscopy performed in the ED; (2) risk stratification using the Glasgow-Blatchford score; (3) nasogastric tube placement; and, finally, (4) an admit-all strategy. In the low-risk scenario, video capsule endoscopy was the preferred strategy (cost $5691, 14.69 quality-adjusted life years [QALYs]) and was more cost-effective than the remaining strategies including nasogastric tube strategy (cost $8159, 14.69 QALYs), risk stratification strategy (cost $10,695, 14.69 QALYs), and admit-all strategy (cost $22,766, 14.68 QALYs). In the moderate-risk scenario, video capsule endoscopy continued to be the preferred strategy (cost $9190, 14.56 QALYs) compared to nasogastric tube (cost $9487, 14.58 QALYs, incremental cost-effectiveness ratio $15,891) and more cost effective than admit-all strategy (cost, $22,584, 14.54 QALYs.) Video capsule endoscopy may be cost-effective for low- and moderate-risk patients presenting to the ED with acute upper GI hemorrhage. Copyright © 2014 Elsevier Inc. All rights reserved.

    Isolated metachronous gastrointestinal metastases from advanced-stage lung cancer are rarely diagnosed on the basis of symptoms and resected. In this report, we present a case of resectable metachronous gallbladder and small intestinal metastases of lung cancer. An 86-year-old woman was treated for lung cancer with resection of the right inferior lobe. Five months after the surgery, she was re-admitted because of melena and anemia. Ultrasonography showed a gallbladder tumor with gastrointestinal hemorrhage, and laparoscopic-assisted cholecystectomy was subsequently performed. However, 2 months after this event, the patient presented again with melena and anemia and was diagnosed with a small intestinal tumor. Therefore, laparoscopic-assisted partial resection of the small intestine was performed. Immunohistochemical staining for thyroid transcription factor-1 and cytokeratin 7 confirmed that the two resected tumors were metachronous metastases of the primary lung cancer. The patient died of liver metastases 5 months after the last surgery. Our experience with this case suggests that surgical resection might not be curative but palliative for patients with isolated gallbladder and small intestinal metastases diagnosed on the basis of melena that is resistant to conservative treatment.

    This case illustrates a rare cause of gastro-intestinal bleeding following bariatric surgery. Though it is essential to rule out common causes of variceal formation accompanied by intermittent, profuse bleeding, there should be a high degree of suspicion of this rare etiology in patients who have previously undergone alteration of their anatomy, especially Roux-en-Y gastric bypass (RYGB). The case emphasizes the need for a multidisciplinary medical-surgical team in evaluating and treating patients who present with complex intra-abdominal pathology. PMID:25155016

    Prinzmetal angina or vasospastic angina is a clinical phenomenon that is often transient and self-resolving. Clinically it is associated with ST elevations on the electrocardiogram, and initially it may be difficult to differentiate from an acute myocardial infarction. The vasospasm induced in this setting occurs in normal or mildly to moderately diseased vessels and can be triggered by a number of etiologies including smoking, changes in autonomic activity, or drug ingestion. While the ischemia induced is usually transient, myocardial infarction and life-threatening arrhythmias can occur in 25% of cases. We present the case of a 65-year-old female where repetitive intermittent coronary vasospasm culminated in transmural infarction in the setting of gastrointestinal bleeding. This case highlights the mortality associated with prinzmetal angina and the importance of recognizing the underlying etiology. PMID:24826293

    The role of angiography in the diagnosis and treatment of gastrointestinal hemorrhage is discussed. Three categories of gastrointestinal bleeding are considered: upper gastrointestinal bleeding due to gastroesophageal varices, upper gastrointestinal bleeding of arterial or capillary origin, and lower gastrointestinal bleeding. The advantages and disadvantages of angiography are compared with those of radionuclide scanning and endoscopy or colonoscopy. It is anticipated that, as radionuclide scans are more widely employed, angiography will eventually be performed only in those patients with positive scans.

    In the Digestive Disease Week in 2015 there have been some new contributions in the field of gastrointestinal bleeding that deserve to be highlighted. Treatment of celecoxib with a proton pump inhibitor is safer than treatment with nonselective NSAID and a proton pump inhibitor in high risk gastrointestinal and cardiovascular patients who mostly also take acetylsalicylic acid. Several studies confirm the need to restart the antiplatelet or anticoagulant therapy at an early stage after a gastrointestinal hemorrhage. The need for urgent endoscopy before 6-12 h after the onset of upper gastrointestinal bleeding episode may be beneficial in patients with hemodynamic instability and high risk for comorbidity. It is confirmed that in Western but not in Japanese populations, gastrointestinal bleeding episodes admitted to hospital during weekend days are associated with a worse prognosis associated with delays in the clinical management of the events. The strategy of a restrictive policy on blood transfusions during an upper GI bleeding event has been challenged. Several studies have shown the benefit of identifying the bleeding vessel in non varicose underlying gastric lesions by Doppler ultrasound which allows direct endoscopic therapy in the patient with upper GI bleeding. Finally, it has been reported that lower gastrointestinal bleeding diverticula band ligation or hemoclipping are both safe and have the same long-term outcomes.

    Lower gastrointestinal hemorrhage accounts for approximately 20% of gastrointestinal hemorrhage. The most common causes of lower gastrointestinal hemorrhage in adults are diverticular disease, inflammatory bowel disease, benign anorectal diseases, intestinal neoplasias, coagulopathies and arterio-venous malformations. Hemangiomas of gastrointestinal tract are rare. Mesenteric hemangiomas are also extremely rare. We present a 25-year-old female who was admitted to the emergency room with recurrent lower gastrointestinal bleeding. An intraluminal bleeding mass inside the small intestinal segment was detected during explorative laparotomy as the cause of the recurrent lower gastrointestinal bleeding. After partial resection of small bowel segment, the histopathologic examination revealed a cavernous hemagioma of mesenteric origin. Although rare, gastrointestinal hemangioma should be thought in differential diagnosis as a cause of recurrent lower gastrointestinal bleeding. PMID:19178725

    A retrospective analysis of prognosis of GIST was used to assess the prognostic effects of hemorrhage of digestive tract induced by mucosal invasion of primary gastrointestinal stromal tumors and related mechanisms. The conclusion is that GISTs with gastrointestinal hemorrhage are more likely to recur, which indicates poor prognosis. Therefore, gastrointestinal hemorrhage may be used as a significant indicator to assess the prognosis of patients. PMID:28589146

    Alveolar hemorrhage occurs relatively rarely and is a therapeutic emergency because it can quickly lead to acute respiratory failure, which can be fatal. Hemoptysis associated with anemia and pulmonary infiltrates suggest the diagnosis of alveolar hemorrhage, but may be absent in one third of cases including patients in respiratory distress. The diagnosis of alveolar hemorrhage is based on the findings of a bronchoalveolar lavage. The causes are numerous. It is important to identify alveolar hemorrhage due to sepsis, then separate an autoimmune cause (vasculitis associated with antineutrophil cytoplasmic antibody, connective tissue disease and Goodpasture's syndrome) with the search for autoantibodies and biopsies from readily accessible organs, from a non-immune cause, performing echocardiography. Lung biopsy should be necessary only in exceptional cases. If the hemorrhage has an immune cause, treatment with steroids and cyclophosphamide may be started. The indications for treatment with rituximab are beginning to be established (forms that are not severe and refractory forms). The benefit of plasma exchange is unquestionable in Goodpasture's syndrome. In patients with an immune disease that can lead to an alveolar hemorrhage, removing any source of infection is the first priority.

  18. Intracranial Hemorrhage

    PubMed Central

    2011-01-01

    Intracranial hemorrhage is a life-threatening condition, the outcome of which can be improved by intensive care. Intracranial hemorrhage may be spontaneous, precipitated by an underlying vascular malformation, induced by trauma, or related to therapeutic anticoagulation. The goals of critical care are to assess the proximate cause, minimize the risks of hemorrhage expansion through blood pressure control and correction of coagulopathy, and obliterate vascular lesions with a high risk of acute rebleeding. Simple bedside scales and interpretation of computed tomography scans assess the severity of neurological injury. Myocardial stunning and pulmonary edema related to neurological injury should be anticipated, and can usually be managed. Fever (often not from infection) is common and can be effectively treated, although therapeutic cooling has not been shown to improve outcomes after intracranial hemorrhage. Most functional and cognitive recovery takes place weeks to months after discharge; expected levels of functional independence (no disability, disability but independence with a device, dependence) may guide conversations with patient representatives. Goals of care impact mortality, with do-not-resuscitate status increasing the predicted mortality for any level of severity of intraparenchymal hemorrhage. Future directions include refining the use of bedside neuromonitoring (electroencephalogram, invasive monitors), novel approaches to reduce intracranial hemorrhage expansion, minimizing vasospasm, and refining the assessment of quality of life to guide rehabilitation and therapy.

    A 55-year-old women developed an aortointestinal fistula between the bifurcation of the aorta and the distal ileum following implantation of multiple endovascular stents into both common iliac arteries for treatment of aortoiliac occlusive disease. Ten months before the acute onset of the gastrointestinal hemorrhage two balloon-expandable steel stents had been implanted into both common iliac arteries. Due to restenosis and recurrent intermittent claudication, three balloon-expandable covered stents were implanted 4 months later on reintervention. The patient presented with abdominal pain and melena, and fell into hemorrhagic shock with signs of upper gastrointestinal bleeding. After transfer to our hospital, she again developed hemorrhagic shock with massive upper and lower gastrointestinal bleeding and died during emergency laparotomy. The development of aortoenteric fistulas following endovascular surgery/stent implantation is very rare and has to be considered in cases of acute gastrointestinal hemorrhage.

    Clinical diagnosis of subperitoneal hemorrhage can be made in a substantial percentage of cases by recognition of a quite constant syndrome—provided the possibility of bleeding is considered. Progressive anemia, as indicated by repeated counts of erythrocytes in the blood or by hematocrit determinations, is confirmation of the diagnosis. The majority of patients recover spontaneously under conservative management. Surgical intervention is indicated if repeated episodes of hemorrhage occur or if the volume of circulating blood cannot be maintained by repeated transfusions of whole blood. PMID:13009511

    Amyloidosis is characterized by the extracellular deposition of amyloid protein in various organs. Gastrointestinal involvement in amyloidosis is common, but a diagnosis of amyloidosis is often delayed. Severe gastrointestinal hemorrhage in amyloidosis is rare but can be fatal in some cases. We experienced a case of a 49-year-old man who presented with recurrent massive hematochezia. Although embolization was performed eight times for bleeding from different sites of the small intestine, hematochezia did not cease. We report the case, with a review of the literature.

    Postpartum hemorrhage (PPH) is a very common obstetric emergency with high morbidity and mortality rates worldwide. Understanding its etiology is fundamental to effectively managing PPH in an acute setting. Active management of the third stage of labor is also a key component in its prevention. Management strategies include conservative measures (medications, uterine tamponade, and arterial embolization) as well as surgical interventions (arterial ligations, compression sutures, and hysterectomy). Creating a standardized PPH protocol and running simulation-based drills with a multidisciplinary team may also help decrease maternal morbidity and improve perinatal outcomes, although further studies are needed.

    Gastrointestinal Stromal Tumors (GISTs) are the most common mesenchymal tumors of the gastrointestinal tract (GIT). Importance of GISTs is increasing while surgeons are facing with more frequent either in emergency setting of elective cases. Delineating the presentation and management of emergency GIST is important. From 2005 to 2014, emergency cases with final diagnosis of GIST were examined retrospectively. Total of 13 operated cases were evaluated by patients characteristics, clinical presentation, operational findings and postoperative prognosis. There were 9 male and 4 female with the mean age of 48.15 years. The most frequent presentations are ileus and GIT hemorrhage both covering the 84% of patients. Small bowel was the dominating site with ileus. Stomach was the second frequent site of the disease with the finding of hemorrhage. Emergency patients are more likely to come with small bowel GIST and obstruction symptoms. Hemorrhage is the most frequent symptom for emergency GIST of stomach and duodenum.

    Gastrointestinal bleeding remains one of the most important emergencies in gastroenterology. Despite this, only about 100 abstracts concerning gastrointestinal bleeding (excluding bleeding complicating endoscopic procedures) were presented at this year's Digestive Disease Week (DDW; 7-10 May 2011; Chicago, Illinois, USA), accounting for less than 2% of all presented lectures and posters. It seems that the number of such abstracts has been decreasing over recent years. This may be due in part to the high level of medical care already achieved, especially in the areas of pharmacotherapy and endoscopic treatment of gastrointestinal bleeding. In this review of gastrointestinal bleeding, priority has been given to large epidemiological studies reflecting "real life," and abstracts dealing more or less directly with endoscopic management. © Georg Thieme Verlag KG Stuttgart · New York.

Submucosal injection of sterile india ink produces a zone of blue-black coloration that is grossly visible from both the mucosal and serosal surfaces. The pathology of gastrointestinal tattoos has only been briefly mentioned previously in the medical literature. We report two cases of gastrointestinal tattooing: one that was done to mark the margin of resection in a patient with gastric lymphoma, and the second that occurred unintentionally following the administration of activated charcoal for drug overdosage in a patient with undiagnosed active inflammatory bowel disease. Unintentional tattooing of the gastrointestinal tract has, therefore, not been reported.

    Postthoracotomy gastrointestinal complications, although relatively uncommon, can be associated with significant morbidity and mortality. It is necessary to identify patients who are at high risk for gastrointestinal complications during the preoperative evaluation. Appropriate stress ulcer prophylaxis should be provided to high-risk patients, and enteral feeds should be initiated as early in the postoperative course as possible. Postoperative hypotension and massive blood transfusions can be avoided with early reexploration in the case of postoperative hemorrhage. Finally, unexplained abdominal pain must not be ignored; a high index of suspicion should be maintained, with early and liberal use of diagnostic tools such as standard radiography, CT, endoscopy, and angiography. Consultation should be requested from a surgeon experienced in abdominal catastrophes. Early laparotomy with aggressive operative management can be lifesaving therapy but must be not applied in a cavalier fashion, as many of these disorders can and should be managed conservatively.

    Gastrointestinal bezoars are a concretion of indigested material that can be found in the gastrointestinal tract of humans and some animals. This material forms an intraluminal mass, more commonly located in the stomach. During a large period of history animal bezoars were considered antidotes to poisons and diseases. We report a historical overview since bezoars stones were thought to have medicinal properties. This magic conception was introduced in South America by Spanish conquerors. In Chile, bezoars are commonly found in a camelid named guanaco (Lama guanicoe). People at Central Chile and the Patagonia believed that bezoar stones had magical properties and they were traded at very high prices. In Santiago, during the eighteenth century the Jesuit apothecary sold preparations of bezoar stones. The human bezoars may be formed by non-digestible material like cellulose (phytobezoar), hair (trichobezoar), conglomerations of medications or his vehicles (pharmacobezoar or medication bezoar), milk and mucus component (lactobezoar) or other varieties of substances. This condition may be asymptomatic or can produce abdominal pain, ulceration, gastrointestinal bleeding, gastric outlet obstruction, perforation and mechanical intestinal obstruction. We report their classification, diagnostic modalities and treatment.

    Complaints related to gastrointestinal gas are commonly encountered in clinical practice. Various therapies have been proposed, yet none has appeared to be extremely effective. A review of the literature revealed little hard evidence to support the use of simethicone, pancreatic enzymes, anticholinergic agents or antibiotics. Evidence supporting the use of prokinetic agents has been the strongest, and there may be a pathophysiologic basis for the use of these agents if the complaints are related to abnormal intestinal motility. The use of activated charcoal for adsorbing intestinal gas has been effective in healthy subjects but has not been properly investigated in patients with gas complaints. Dietary modification may be beneficial in certain cases. Additional controlled trials are necessary to clarify the issues in the treatment of this common problem. PMID:3058280

    1978-01-01

    In 95 consecutive cases of cavaderic renal transplantation followed up for 1 to 83 months (mean 23.1 months) 17 complications developed in the upper gastrointestinal tract of 15 patients; these included duodenal ulcer in 12 and gastric ulcer, esophagitis, hemorrhagic gastritis, small-bowel obstruction and small-bowel perforation in 1 each. The occurrence of a complication was not related to the patient's age, sex, blood group or use of cigarettes or alcohol, the duration of hemodialysis before transplantation, the tissue match or the number of infusions of immunosuppressive medication. One patient died of the complication. The peptic ulcers that developed after transplantation were successfully managed conservatively in 69% of cases. Since surgical treatment in patients whose immune response has been suppressed is associated with an increased frequency of complications such as disruption of suture lines, it is preferable to reserve it for those in whom complications develop that are unresponsive to conservative measures.

    2015-01-01

    Objectives: Studies report that the risks of significant neurologic complications (including stroke, cerebral abscess, and migraine) and hemorrhagic sequelae are high in patients with hereditary hemorrhagic telangiectasia (HHT), and that life expectancy in this cohort is reduced. However, most published cohorts derive from specialist centers, which may be susceptible to bias. Methods: We used a population-based approach to estimate the risks of developing neurologic and hemorrhagic complications of HHT, the association of a diagnosis of HHT with common cardiovascular and malignant comorbidities, and also long-term survival of those with the disease. Results: From a UK primary care database of 3.5 million patients (The Health Improvement Network), we identified 675 cases with a diagnosis of HHT and compared them with 6,696 controls matched by age, sex, and primary care practice. Risks of stroke (odds ratio [OR] 1.8, 95% confidence interval [CI] 1.2–2.6), cerebral abscess (OR 30.0, CI 3.1–288), and migraine (OR 1.7, CI 1.3–2.2) were elevated over controls. Bleeding complications including epistaxis (OR 11.6, CI 9.1–14.7) and gastrointestinal hemorrhage (OR 6.1, CI 2.8–13.4) were more common in cases with HHT. Survival of cases with HHT was poorer than controls with a hazard ratio for death of 2.0 (CI 1.6–2.6) and a median age at death 3 years younger. Conclusions: Patients with HHT are at substantially increased risk of serious neurologic and hemorrhagic complications of the disease. Because a diagnosis of HHT is associated with a significantly poorer survival compared with those who have no disease, evaluation of new strategies to improve clinical management is required.

    This article reviews the epidemiology, pathophysiology, and clinical management of patients with suspected or confirmed viral hemorrhagic fever infection. The focus is on clinical management based on case series from naturally occuring outbreaks of viral hemorrhagic fever infection as well as imported cases of viral hemorrhagic fever encountered in industrialized nations. The potential risk of bioterrorism involving these agents is discussed as well as emergency department and critical care management of isolated cases or larger outbreaks. Important aspects of management, including recognition of infected patients, isolation and decontamination procedures, as well as available vaccines and therapies are emphasized.

    Ebola hemorrhagic fever is an often-fatal disease caused by a virus of the Filoviridae family, genus Ebolavirus. Initial signs and symptoms of the disease are nonspecific, often progressing on to a severe hemorrhagic illness. Special Operations Forces Medical Providers should be aware of this disease, which occurs in sporadic outbreaks throughout Africa. Treatment at the present time is mainly supportive. Special care should be taken to prevent contact with bodily fluids of those infected, which can transmit the virus to caregivers.

    We report a patient with small intestinal metastasis from lung squamous cell carcinoma. A 66-year-old man who underwent radical lung cancer surgery was admitted to our hospital. Before starting his fifth cycle of chemotherapy, he was found to have a positive fecal occult blood test. Abdominal computed tomography scan revealed an ileal tumor with mesenteric lymph node enlargement. He underwent laparoscopic resection of the involved small intestine and mesentery. Histopathological analysis confirmed metastasis from lung cancer. We conducted a review of the literature and 64 documented cases of small intestinal metastasis from lung cancer were found. The pathologic diagnosis, clinical presentation, site of metastasis, and survival time in these cases were reviewed.

    A prospective study was performed to evaluate the epidemiological characteristics and clinical outcome of patients with upper digestive bleeding. Between April 1987 and May 1993, 741 patients, 517 men and 224 women, with a mean age of 50.48 years (range, 12 to 94) were admitted to the emergency department with this diagnosis. The chief complaint was tarry stool (88.4%). A total of 717 patients underwent endoscopic examination within a mean time of 17.2 hours of arrival at the emergency department. Duodenal ulcers were found in 216 (35.9%) patients, gastric ulcer in 240 (32.4%), gastritis in 74 (10%), esophageal varices in 38 (5.1%), and other causes in 121 patients (16.5%). 478 required blood transfusion (range of 1 to 15 blood units transfused). 80.4% of patients who died necessitated transfusion versus 62.5% of the patients who had a satisfactory outcome. A total of 672 cases (92%) were managed with medical therapy. In 90 cases (12.2%) endoscopic injection treatment with 75% alcohol was performed. 60 patients (8.18%) had surgical therapy, 81.7% of whom underwent emergency operation to arrest bleeding. The global mortality was 10.6% (78 of 741 patients), compared to 18.3% in patients who were operated. The highest mortality occurred in patients with esophageal varices. We conclude that peptic ulcer is still the mayor cause of upper digestive bleeding. The high mortality found in patients who required surgical therapy creates the need to select those patients who may get benefits of alternate therapies which may improve the outcome.

    The study goal was to evaluate the efficacy, safety, and clinical outcome of transarterial embolization for postoperative hemorrhage after abdominal surgery. Thirty-three patients were referred for angiography because of gastrointestinal or intra-abdominal bleeding after abdominal surgery. Urgent angiography and transarterial embolization was performed in all 33 patients. The clinical and angiographic features were retrospectively reviewed. Angiography revealed a discrete bleeding focus in 26 (79%) of 33 patients. Transarterial embolization was technically successful in 24 (92%) of 26 patients with a discrete bleeding focus. Rebleeding occurred in four (17%) of 24 patients. They were successfully managed with repeat embolization. There was no procedure-related complication during follow-up period. Angiography has a high detection rate of bleeding site in patients with postoperative hemorrhage after abdominal surgery. Transarterial embolization is considered to be an effective and safe means in the management of postoperative hemorrhage.

    The number of sample cases of colonic diverticular hemorrhage treated with endoscopic band ligation (EBL) has been small to date. To elucidate the safety and efficacy of EBL for colonic diverticular hemorrhage. Retrospective study. General hospital. A total of 29 patients with 31 colonic diverticula with stigmata of recent hemorrhage (SRH). Urgent colonoscopy was performed after bowel preparation. When diverticula with SRH were identified, marking with hemoclips was done near the diverticula. The endoscope was removed and reinserted after a band-ligator device was attached to the tip of endoscope. At first, EBL was attempted. In patients who could not be treated with EBL, epinephrine injection or endoscopic clipping was performed. Procedure time, rate of hemostasis and rebleeding, complications. The mean procedure time was 47 ± 19 minutes. EBL was successfully completed in 27 colonic diverticula (87%); except in 3 diverticula with a small orifice and large dome and 1 diverticula in which the orifice was too large. Early rebleeding after EBL occurred in 3 of 27 cases (11%). Although 2 cases of sigmoid rebleeding could be managed by repeat EBL or conservatively, right hemicolectomy was performed in 1 ascending diverticulum, in which the bleeding source was not identified on repeat colonoscopy. Scar formation at previously banded diverticula was identified in 7 of 11 patients who underwent follow-up colonoscopy. There were no complications after EBL in any of the patients. Retrospective study. EBL is a safe and effective treatment for colonic diverticular hemorrhage, and colonic diverticula resolve after EBL.

    Lugol's solution is an iodinated agent used for treating thyroid crisis. It is primarily used in diagnostic tests for esophageal diseases. However, Lugol's solution can cause local mucosal injury and hemorrhage. We report, for the first time, a case of 34-year-old man who exhibited severe duodenal hemorrhage induced by Lugol's solution that was used to treat thyroid crisis. The quantity of Lugol's solution used for treating thyroid crisis is much higher than that used for mucosal disease investigation. Clinical practitioners should be aware of gastrointestinal hemorrhage when using Lugol's solution for the treatment of thyroid crisis.

    Viral hemorrhagic septicemia (VHS) is one of the most important viral diseases of finfish worldwide. In the past, VHS was thought to affect mainly rainbow trout Oncorhynchus mykiss reared at freshwater facilities in Western Europe where it was known by various names including Egtved disease and infectious kidney swelling and liver degeneration (Wolf 1988). Today, VHS is known as an important source of mortality for cultured and wild fish in freshwater and marine environments in several regions of the northern hemisphere (Dixon 1999; Gagné et al. 2007; Kim and Faisal 2011; Lumsden et al. 2007; Marty et al. 1998, 2003; Meyers and Winton 1995; Skall et al. 2005b; Smail 1999; Takano et al. 2001). Viral hemorrhagic septicemia is caused by the fish rhabdovirus, viral hemorrhagic septicemia virus (VHSV), a member of the genus Novirhabdovirus of the family Rhabdoviridae

    Darier disease is an autosomal-dominant inherited condition caused by mutation of a gene, which produces a protein involved in calcium channel regulation. The disease has a variety of manifestations and lacks consistent genotype-phenotype correlations. Acral hemorrhagic Darier disease causes macules, papules, vesicles and/or hemorrhagic blisters on the extremities. Other classic signs of the disease may be present in the same patient or relatives. Histopathology reveals dyskeratosis and suprabasal acantholysis with hemorrhagic lacunae. We report 3 new cases of this type of Darier disease triggered by injuries.

    Spontaneous subarachnoid hemorrhage (SAH) typically prompts a search for an underlying ruptured saccular aneurysm, which is the most common nontraumatic cause. Depending on the clinical presentation and pattern of SAH, the differential diagnosis may include a diverse group of causes other than aneurysm rupture. For the purposes of this review, we classify SAH into three main patterns, defined by the distribution of blood on unenhanced CT: diffuse, perimesencephalic, and convexal. The epicenter of the hemorrhage further refines the differential diagnosis and guides subsequent imaging. Additionally, we review multiple clinical conditions that can simulate the appearance of SAH on CT or MRI, an imaging artifact known as pseudo-SAH.

    2004-01-01

    This review addresses the pathophysiology and treatment of hemorrhagic shock – a condition produced by rapid and significant loss of intravascular volume, which may lead sequentially to hemodynamic instability, decreases in oxygen delivery, decreased tissue perfusion, cellular hypoxia, organ damage, and death. Hemorrhagic shock can be rapidly fatal. The primary goals are to stop the bleeding and to restore circulating blood volume. Resuscitation may well depend on the estimated severity of hemorrhage. It now appears that patients with moderate hypotension from bleeding may benefit by delaying massive fluid resuscitation until they reach a definitive care facility. On the other hand, the use of intravenous fluids, crystalloids or colloids, and blood products can be life saving in those patients who are in severe hemorrhagic shock. The optimal method of resuscitation has not been clearly established. A hemoglobin level of 7–8 g/dl appears to be an appropriate threshold for transfusion in critically ill patients with no evidence of tissue hypoxia. However, maintaining a higher hemoglobin level of 10 g/dl is a reasonable goal in actively bleeding patients, the elderly, or individuals who are at risk for myocardial infarction. Moreover, hemoglobin concentration should not be the only therapeutic guide in actively bleeding patients. Instead, therapy should be aimed at restoring intravascular volume and adequate hemodynamic parameters. PMID:15469601

    Major obstetric hemorrhage remains the leading cause of maternal mortality and morbidity worldwide, and is associated with a high rate of substandard care. A well-defined and multidisciplinary approach that aims to act quickly and avoid omissions or conflicting strategies is key. The most common etiologies of hemorrhage are abruptio placenta, placenta previa/accreta, uterine rupture in the antepartum period and retained placenta, uterine atony, and genital-tract trauma in the postpartum period. Basic treatment of postpartum hemorrhage relies on manual removal of the placenta or manual exploration of the uterus plus bladder emptying and oxytocin administration. If this does not arrest bleeding, or if there is any suspicion of genital-tract trauma, examination of the vagina and cervix with appropriate valves and analgesia/anesthesia must follow quickly. Postpartum uterine atony resistant to oxytocin must be treated with prostaglandin within 15 to 30 minutes; uterine balloon tamponade can be also useful at this stage. Aggressive transfusion therapy and resuscitation are mandatory in major obstetric hemorrhage. Specific invasive treatment must be considered within no more than 30 to 60 minutes, if previous measures have failed -- and even earlier in some particular etiologies. The two main options are radiologic embolization and surgical artery ligations. Recombinant factor VIIa may also be considered, but should not delay the performance of a life-saving procedure such as embolization or surgery. Hysterectomy must be implemented when all other interventions have failed.

    Ibuprofen is used for the closure of ductus arteriosus either intravenously or enterally. Although intraventricular hemorrhage, necrotizing enterocolitis, bronchopulmonary dysplasia, transient renal failure, oliguria, hyponatremia and thrombocytopenia are reported complications during or after ibuprofen treatment, gastrointestinal bleeding, to our knowledge, has not been reported previously. We herein report a premature newborn, in whom ibuprofen was used intravenously for the closure of ductus arteriosus and gastrointestinal bleeding developed as a complication, and aim to discuss this rare adverse effect. In conclusion, we emphasize the importance of close follow-up of premature newborns during intravenous ibuprofen treatment considering also the other rare systemic side effects reported in the literature.

    The aim of the present study was to identify computed tomography (CT) features to assist in differentiating gastrointestinal schwannomas from gastrointestinal stromal tumors (GISTs). CT images of gastrointestinal schwannomas (n=15) and GISTs (n=50) were analyzed. The absolute CT values of tumor/aorta during plain scan/arterial phase/venous phase were recorded as tumor plain scan (Tp)/aorta plain scan (Ap), tumor arterial phase (Ta)/aorta arterial phase (Aa) and tumor venous phase (Tv)/aorta venous phase (Av), respectively, and normalized CT values of the three phases were calculated as Sp=Tp/Ap, Sa=Ta/Aa and Sv=Tv/Av, respectively. The difference in tumor CT value between arterial and venous phases was calculated and recorded as Tv-a. CT data including tumor size, contour, margin, growth pattern, presence of calcification, cystic change, hemorrhage, ulceration, perilesional lymph nodes (PLNs), local invasion to surrounding structures, metastasis, ascites, vasculatures, enhancement pattern/degree, Tp/Ta/Tv and Sp/Sa/Sv were evaluated for each patient. Receiver operating characteristic (ROC) curve analysis was used to assess the ability of the CT data to differentiate gastrointestinal schwannomas from GISTs. Compared with GISTs, gastrointestinal schwannomas more frequently demonstrated round contouring, relatively smaller tumor size, a homogeneous enhancement pattern, with the presence of PLNs and a higher level of vasculature (P<0.05), whilst the presence of cystic changes were more common in GISTs compared with gastrointestinal schwannomas (P<0.05). The Sa, Ta and Tv-a of gastrointestinal schwannomas were less compared with those of GISTs (P<0.05). The difference in margin, growth pattern, intra-tumoral calcifications and hemorrhage were insignificant (P>0.05). ROC analysis indicated that tumor size, cystic change, the presence of PLNs, tumor enhancement pattern and Sa demonstrated improved diagnostic potential compared with others [area under the curve (AUC) >0

    1975-12-06

    The cause of upper gastrointestinal bleeding was studied in 85 cirrhotic patients by emergency endoscopy. In every patient, one or several lesions were observed and the site of bleeding was ascertained in 59. The two main causes were oesophago-gastric varices (46 p.cent) and acute mucosal lesions(42 p.cent). The source of bleeding appeared to be related to the degree of liver function impairment. In patients with no or moderate liver function impariment, bleeding usually originated from varices or from drug-associated mucosal erosions. Patients with severe impairment of liver function most often bled from spontaneous acute oeso-gastro-duodenal ulcerations. These ulcerations resembled what has been described in "stress" hemorrhage. Because of the relationship between liver function and the cause of hemorrhage, mortality was lower in variceal bleeders (29 p.cent) than in patients with spontaneous ulcerations (83 p.cent). In patients with severely impaired liver function, portacaval shunt was rarely indicated since hemorrhage was generally due to acute mucosal ulcerations.

  8. Gastrointestinal Morbidity in Obesity

    Obesity is a complex disease that results from increased energy intake and decreased energy expenditure. The gastrointestinal system plays a key role in the pathogenesis of obesity and facilitates caloric imbalance. Changes in gastrointestinal hormones and the inhibition of mechanisms that curtail caloric intake result in weight gain. It is not clear if the gastrointestinal role in obesity is a cause or an effect of this disease. Obesity is often associated with type 2 diabetes mellitus (T2DM) and cardiovascular diseases (CVD). Obesity is also associated with gastrointestinal disorders, which are more frequent and present earlier than T2DM and CVD. Diseases such as gastro-esophageal reflux disease, cholelithiasis or non-alcoholic steatohepatitis are directly related to body weight and abdominal adiposity. Our objective is to assess the role of each gastrointestinal organ in obesity and the gastrointestinal morbidity resulting in those organs from effects of obesity. PMID:24602085

    Brain hemorrhage is the most fatal form of stroke and has the highest morbidity of any stroke subtype. Intraventricular extension of hemorrhage (IVH) is a particularly poor prognostic sign, with expected mortality between 50% and 80%. IVH is a significant and independent contributor to morbidity and mortality, yet therapy directed at ameliorating intraventricular clot has been limited. Conventional therapy centers on managing hypertension and intracranial pressure while correcting coagulopathy and avoiding complications such as rebleeding and hydrocephalus. Surgical therapy alone has not changed the natural history of the disease significantly. However, fibrinolysis in combination with extraventricular drainage shows promise as a technique to reduce intraventricular clot volume and to manage the concomitant complications of IVH.

    2010-01-01

    Nontraumatic subarachnoid hemorrhage is a neurosurgical emergency characterized by the extravasation of blood into the spaces covering the central nervous system that are filled with cerebrospinal fluid. The leading cause of nontraumatic subarachnoid hemorrhage is rupture of an intracranial aneurysm, which accounts for about 80 percent of cases and has a high rate of death and complications. The management of aneurysmal SAH has changed significantly over the past few years. This change is mostly due to the demonstration of the superiority of early diagnosis, surgical clipping or endovascular embolization of ruptured aneurysms. This superiority derives from the relative safety of early aneurysm occlusion and the major threat of early rebleeding (approximately 25% in three weeks after SAH).

    /sup 99m/Tc sulfur colloid scintigraphy is a technique which can be used to localize sites of lower gastrointestinal hemorrhage. Two reports of patients illustrate its use clinically. This procedure is non-invasive, relatively inexpensive, easily performed and has a high degree of sensitivity. The technique may, in some instances, replace angiography or endoscopy as the initial procedure used to diagnose the site of lower gastrointestinal bleeding or, more likely, serve as a complementary diagnostic modality.

    Very rarely, spinal subarachnoid hemorrhage (SSAH) can occur without any direct spinal injury in patients with traumatic intracranial SAH. A-59-year-old male with traumatic intracranial subarachnoid hemorrhage (SAH) presented with pain and numbness in his buttock and thigh two days after trauma. Pain and numbness rapidly worsened and perianal numbness and voiding difficulty began on the next day. Magnetic resonance imaging showed intraspinal hemorrhage in the lumbosacral region. The cauda equina was displaced and compressed. Emergent laminectomy and drainage of hemorrhage were performed and SSAH was found intraoperatively. The symptoms were relieved immediately after the surgery. Patients with traumatic intracranial hemorrhage who present with delayed pain or neurological deficits should be evaluated for intraspinal hemorrhage promptly, even when the patients had no history of direct spinal injury and had no apparent symptoms related to the spinal injury in the initial period of trauma.

    Recent data indicate that in patients with hereditary hemorrhagic teleangiectasia (HHT), low iron levels due to inadequate replacement after hemorrhagic iron losses are associated with elevated factor-VIII plasma levels and consecutively increased risk of venous thrombo-embolism. Here, we report a patient with HHT, low iron levels, elevated factor-VIII, and recurrent venous thrombo-embolism. A 64-year-old multimorbid Serbian gipsy was diagnosed with HHT at age 62 years. He had a history of recurrent epistaxis, teleangiectasias on the lips, renal and pulmonary arterio-venous malformations, and a family history positive for HHT. He had experienced recurrent venous thrombosis (mesenteric vein thrombosis, portal venous thrombosis, deep venous thrombosis), insufficiently treated with phenprocoumon during 16 months and gastro-intestinal bleeding. Blood tests revealed sideropenia and elevated plasma levels of coagulation factor-VIII. His history was positive for diabetes, arterial hypertension, hyperlipidemia, smoking, cerebral abscess, recurrent ischemic stroke, recurrent ileus, peripheral arterial occluding disease, polyneuropathy, mild renal insufficiency, and epilepsy. Following recent findings, hypercoagulability was attributed to the sideropenia-induced elevation of coagulation factor-VIII. In conclusion, HHT may be associated with hypercoagulability due to elevated factor-VIII associated with low serum iron levels from recurrent bleeding. Iron substitution may prevent HHT patients from hypercoagulability. PMID:26167029

    2011-01-01

    Gastrointestinal tract is the most common extranodal site involved by lymphoma with the majority being non-Hodgkin type. Although lymphoma can involve any part of the gastrointestinal tract, the most frequent sites in order of its occurrence are the stomach followed by small intestine and ileocecal region. Gastrointestinal tract lymphoma is usually secondary to the widespread nodal diseases and primary gastrointestinal tract lymphoma is relatively rare. Gastrointestinal lymphomas are usually not clinically specific and indistinguishable from other benign and malignant conditions. Diffuse large B-cell lymphoma is the most common pathological type of gastrointestinal lymphoma in essentially all sites of the gastrointestinal tract, although recently the frequency of other forms has also increased in certain regions of the world. Although some radiological features such as bulky lymph nodes and maintenance of fat plane are more suggestive of lymphoma, they are not specific, thus mandating histopathological analysis for its definitive diagnosis. There has been a tremendous leap in the diagnosis, staging and management of gastrointestinal lymphoma in the last two decades attributed to a better insight into its etiology and molecular aspect as well as the knowledge about its critical signaling pathways.

    2016-09-01

    The main innovations of the latest meeting of the Gastroenterological Association (2016) concerning upper gastrointestinal bleeding from the clinician's perspective can be summarised as follows: a) The Glasgow-Blatchford scale has the best accuracy in predicting the need for surgical intervention and hospital mortality; b) Prognostic scales for non-variceal upper gastrointestinal bleeding are also useful for lower gastrointestinal bleeding; c) Preliminary data suggest that treatment with hemospray does not seem to be superior to current standard treatment in controlling active peptic ulcer bleeding; d) Either famotidine or a proton pump inhibitor may be effective in preventing haemorrhagic recurrence in patients taking aspirin, but this finding needs to be confirmed in further studies; e) There was confirmation of the need to re-introduce antiplatelet therapy as early as possible in patients with antiplatelet-associated gastrointestinal bleeding in order to prevent cardiovascular mortality; f) Routine clinical practice suggests that gastrointestinal or cardiovascular complications with celecoxib or traditional NSAIDs are very low; g) Dabigatran is associated with an increased incidence of gastrointestinal bleeding compared with apixaban or warfarin. At least half of the episodes are located in the lower gastrointestinal tract; h) Implant devices for external ventricular circulatory support are associated with early gastrointestinal bleeding in up to one third of patients; the bleeding is often secondary to arteriovenous malformations.

    2003-11-01

    Perforations of the gastrointestinal tract have many causes. Holes in the wall of gastrointestinal organs can be created by blunt or penetrating trauma, iatrogenic injury, inflammatory conditions that penetrate the serosa or adventitia, extrinsic neoplasms that invade the gastrointestinal tract, or primary neoplasms that penetrate outside the wall of gastrointestinal organs. This article provides a radiologic approach for investigating the wide variety of gastrointestinal perforations. General principles about contrast agents and studies are reviewed, and then perforations in specific gastrointestinal organs are discussed.

    This study reports major gastrointestinal complications in a group of 416 patients following kidney transplantation. Three hundred and ninety-nine patients received a cadaveric kidney while the other 17 received a living related organ. The immunosuppressive regimen changed somewhat during the course of the study but included azathioprine, prednisolone, antilymphocyte globulin, and cyclosporin. Perforations occurred in the colon (n = 6), small bowel (n = 4), duodenum (n = 2), stomach (n = 1), and esophagus (n = 1). There were five cases of acute pancreatitis, four of upper gastrointestinal and two of lower intestinal hemorrhage, two of acute appendicitis, one of acute cholecystitis, one postoperative mesenteric infarction, and two small bowel obstructions. Fifty percent of the complications occurred while patients were being given high-dose immunosuppression to manage either the early postoperative period or episodes of acute rejection. Ten percent of the complications had an iatrogenic cause. Of the 31 patients affected, 10 (30%) died as a direct result of their gastrointestinal complication. This high mortality appears to be related to the effects of the immunosuppression and the associated response to sepsis. Reduction of these complications can be achieved by improved surgical management, preventive measures, prompt diagnosis, and a reduced immunosuppressive protocol.

  5. Swallowable fluorometric capsule for wireless triage of gastrointestinal bleeding.

    PubMed

    2015-12-07

    Real-time detection of gastrointestinal bleeding remains a major challenge because there does not yet exist a minimally invasive technology that can both i) monitor for blood from an active hemorrhage and ii) uniquely distinguish it from blood left over from an inactive hemorrhage. Such a device would be an important tool for clinical triage. One promising solution, which we have proposed previously, is to inject a fluorescent dye into the blood stream and to use it as a distinctive marker of active bleeding by monitoring leakage into the gastrointestinal tract with a wireless fluorometer. This paper reports, for the first time to our knowledge, the development of a swallowable, wireless capsule with a built-in fluorometer capable of detecting fluorescein in blood, and intended for monitoring gastrointestinal bleeding in the stomach. The embedded, compact fluorometer uses pinholes to define a microliter sensing volume and to eliminate bulky optical components. The proof-of-concept capsule integrates optics, low-noise analog sensing electronics, a microcontroller, battery, and low power Zigbee radio, all into a cylindrical package measuring 11 mm × 27 mm and weighing 10 g. Bench-top experiments demonstrate wireless fluorometry with a limit-of-detection of 20 nM aqueous fluorescein. This device represents a major step towards a technology that would enable simple, rapid detection of active gastrointestinal bleeding, a capability that would save precious time and resources and, ultimately, reduce complications in patients.

    We present a case of a patient with a failed pancreaticoduodenal allograft with exocrine enteric-drainage who developed catastrophic gastrointestinal (GI) hemorrhage. Over the course of a week, she presented with recurrent GI bleeds of obscure etiology. Multiple esophago-gastro-duodenoscopic (EGD) and colonoscopic evaluations failed to reveal the source of the hemorrhage. A capsule endoscopy and a technetium-labeled red blood cells (RBC) imaging study were similarly unrevealing for source of bleeding. She subsequently developed hemorrhagic shock requiring emergent superior mesenteric arteriography. Run off images revealed an external iliac artery aneurysm with fistulization into the jejunum. Coiled embolization was attempted but abandoned because of hemodynamic instability. Deployment of a covered endovascular stent into the right external iliac artery over the fistula site resulted in immediate hemodynamic stabilization. A high index of suspicion for arterioenteric fistulae is needed for diagnosis of this uncommon but eminently treatable form of GI hemorrhage in this patient population. PMID:24455393

    Gross and microscopic lesions associated with Bolivan hemorrhagic fever virus infection in the rhesus monkey were studied in 10 animals which died following inoculation. Gross lesions included skin rash, lymphadenopathy, splenomegaly, meningeal edema, hydropericardium and enlarged friable livers. Hemorrhagic manifestations of the infection were not consistently observed, but hemorrhages were present in the skin, heart, brain and nares in some monkeys. Histopathologic lesions were fairly consistent. Hepatic necrosis with the presence of acidophilic hyaline bodies, necrotizing enteritis, epithelial necrosis and adrenal cortical necrosis were present in all monkeys. Those monkeys which died after the seventeenth day of infection had nonsupurative meningoencephalitis; lymphoid necrosis was present in 3 monkeys that died after day 18. Other microscopic lesions included myocardial degeneration, lymphoid and reticuloendothelial cell hyperplasia and lymphoid depletion. Most of the histopathologic lesions described in human autopsy material were reproduced; however, the necrosis in the skin and oral mucosa, mucosa of the gastrointestinal tract and the adrenal cortex have not been described in man. Despite these apparent discrepancies the results of this investigation indicate that the rhesus monkey is a good experimental model for the study of Bolivian hemorrhagic fever infection.

    Nontraumatic subarachnoid hemorrhage from intracranial aneurysm rupture presents with sudden severe headache. Initial treatment focuses on airway management, blood pressure control, and extraventricular drain for hydrocephalus. After identifying the aneurysm, they may be clipped surgically or endovascularly coiled. Nimodipine is administered to maintain a euvolemic state and prevent delayed cerebral ischemia (DCI). Patients may receive anticonvulsants. Monitoring includes serial neurologic assessments, transcranial Doppler ultrasonography, computed tomography perfusion, and angiographic studies. Treatment includes augmentation of blood pressure and cardiac output, cerebral angioplasty, and intra-arterial infusions of vasodilators. Although early mortality is high, about one half of survivors recover with little disability. Copyright © 2014 Elsevier Inc. All rights reserved.

    Bleeding complications of dengue hemorrhagic fever such as epistaxis, gum bleeding, gastrointestinal bleeding, hypermenorrhea, hematuria, and thrombocytopenia have been documented. A 49-year-old female presented with complaints of intermittent high-grade fever for the past 4 days, lower abdominal pain and altered sensorium for 1 day. Laboratory investigations revealed severe anemia, mild thrombocytopenia, hypofibrinogenemia, and positive dengue serology. Emergency ultrasound examination of the abdomen revealed a possible rapidly expanding hematoma from the inferior epigastric artery and suggested urgent computed tomography (CT) angiogram for confirmation of the same. CT angiogram was confirmatory, and patient underwent emergency embolization of the right inferior epigastric artery. We report the first case of inferior epigastric hemorrhage and rectus sheath hematoma as a consequence of dengue. PMID:27275081

    This article surveys the most important gastrointestinal parasites that affect humans. The modes of acquisition, pathology, epidemiology, diagnosis, and treatment are all briefly examined. Gastrointestinal parasites have become increasingly important in the differential diagnosis of gastrointestinal disease, as a result of a number of circumstances. These circumstances include: increasing travel to developing countries; increased numbers, for one reason or another, of immunocompromised individuals; increased consumption of raw or partially cooked ethnic delicacies; more crowding in day-care centres; increased immigration from developing countries; and an endemic pocket of individuals with certain unhygienic or unsanitary practices.

    PubMed

    Roessler, M; Bode, K; Bauer, M

    2014-10-01

    How fluid resuscitation has to be performed for acute hemorrhage situations is still controversially discussed. Although the forced administration of crystalloids and colloids has been and still is practiced, nowadays there are good arguments that a cautious infusion of crystalloids may be initially sufficient. Saline should no longer be used for fluid resuscitation. The main argument for cautious fluid resuscitation is that no large prospective randomized clinical trials exist which have provided evidence of improved survival when fluid resuscitation is applied in an aggressive manner. The explanation that no positive effect has so far been observed is that fluid resuscitation is thought to boost bleeding by increasing blood pressure and dilutional coagulopathy. Nevertheless, national and international guidelines recommend that fluid resuscitation should be applied at the latest when hemorrhage causes hemodynamic instability. Consideration should be given to the fact that damage control resuscitation per se will neither improve already reduced tissue perfusion nor hemostasis. In acute and possibly rapidly progressing hypovolemic shock, colloids can be used. The third and fourth generations of hydroxyethyl starch (HES) are safe and effective if used correctly and within prescribed limits. If fluid resuscitation is applied with ongoing re-evaluation of the parameters which determine oxygen supply, it should be possible to keep fluid resuscitation restricted without causing undesirable side effects and also to administer a sufficient quantity so that survival of patients is ensured.

    Argentine hemorrhagic fever (AHF), an acute disease caused by Junin virus (JUNV, Arenaviridae), has been an important issue to public health in Argentina since the early 1950s. The field rodent Calomys musculinus is JUNV natural reservoir and human disease is a consequence of contact with infected rodents. A steady extention of AHF endemic area is being observed since the first reports of the disease. Important achievements have been made in: (a) improvement of methods for the etiological diagnosis; (b) implementation and validation of therapeutical measures; (c) development of vaccines to protect against AHF. Reference is made to different research strategies used to obtain anti-AHF vaccines in the past and anti-arenaviral diseases in the present. Information is updated on features and field performance of Candid #1 vaccine, a live attenuted vaccine currently used to prevent AHF. This vaccine was developed through a joint international effort that envisioned it as an orphan drug. With transferred technology, Argentine government was committed to be Candid #1 manufacturer and to register this vaccine as a novel medical product under the Argentine regulatory authority. Candid #1 vaccine is the first one used to control an arenaviral hemorrhagic fever, the first live viral vaccine to be manufactured and registered in Argentina, reaching its target population through governmental effort.

    Introduction. Mural intestinal hematoma (MIH) is an uncommon complication of anticoagulant therapy. Hemorrhagic shock has been rarely reported as a revealing modality. Results. We report two cases of shock induced by mural intestinal hematoma in patients under oral anticoagulant for aortic prosthetic valve and atrial fibrillation. Patients were admitted to the ICU for gastrointestinal tract bleeding associated with hemodynamic instability. After resuscitation, an abdominal CT scan has confirmed the diagnosis showing an extensive hematoma. Medical treatment was sufficient and there was no need for surgery. Conclusion. Gastrointestinal bleeding associated with shock in patients treated by oral anticoagulant should alert physicians to research a probable MIH. Urgent diagnosis and appropriate medical treatment can avoid surgical interventions. PMID:28299212

    2010-01-01

    Gastrointestinal disease is often overlooked or simply forgotten as a cause of osteoporosis. Yet, the consequences of osteoporotic fractures can be devastating. Although the bulk of the published experience regarding osteoporosis is derived from the postmenopausal population, this review will focus on gastrointestinal disorders implicated in osteoporosis, with an emphasis on inflammatory bowel disease and celiac disease. The unique aspects of gastrointestinal diseases associated with osteoporosis include early onset of disease (and, therefore, prolonged exposure to risk factors for developing osteoporosis, particularly with inflammatory bowel disease and celiac disease), malabsorption, and maldigestion of nutrients necessary for bone health and maintenance (eg, calcium, vitamin D), as well as the impact of glucocorticoids. These factors, when added to smoking, a sedentary lifestyle, hypogonadism, and a family history of osteoporosis, accumulate into an imposing package of predictors for osteoporotic fracture. This paper will review the identification and treatment strategies for patients with gastrointestinal disorders and osteoporosis. PMID:20978554

    Abstract Spontaneous intracerebral hemorrhage (sICH) is one of the most dangerous cerebrovascular diseases, especially when in deep brain. The treatment of spontaneous deep supratentorial intracerebral hemorrhage is still controversial. We conducted a retrospective case-control study using propensity score matching to compare the efficacy of surgery and conservative treatment for patients with deep surpatentorial hemorrhage. We observed the outcomes of consecutive patients with spontaneous deep supratentorial hemorrhage retrospectively from December 2008 to July 2013. Clinical outcomes of surgery and conservative treatments were compared in patients with deep sICH using propensity score matching method. The primary outcome was neurological function status at 6 months post ictus. The second outcomes included mortality at 30 days and 6 months, and the incidence of complications. Subgroup analyses of 6-month outcome were conducted. Sixty-three (22.66%) of the 278 patients who received surgery had a favorable neurological function status at 6 months, whereas in the conservative group, 66 of 278 (23.74%) had the same result (P = 0.763). The 30-day mortality in the surgical group was 19.06%, whereas 30.58% in the conservative group (P = 0.002). There was significant difference in the mortality at 6 months after ictus as well (23.38% vs 36.33%, P = 0.001). The subgroup analyses showed significantly better outcomes for the surgical group when hematoma was >40 mL (13.33% vs 0%, P = 0.005) or complicated with intraventricular hemorrhage (16.67% vs 7.27%, P = 0.034). For complications, the risk of pulmonary infection, gastrointestinal hemorrhage, urinary infection, pulmonary embolus, and need for tracheostomy/long term ventilation in the surgical group was higher than the conservative group (31.29% vs 15.47%, P < 0.001; 6.83% vs 3.96%, P = 0.133; 2.88% vs 1.80%, P = 0.400; 1.80% vs 1.08%, P = 0.476; 32.73% vs 23.38%, P = 0

    The incidence of gastrointestinal involvement is relatively observed in patients with vasculitis processes. Vasculitis can be primary (necrotising or hypersensitivity) or secondary to another primary disease. Gastrointestinal involvement is present in up to 50% of the various forms of systemic vasculitis. Primary or secondary vasculitic process, according to the classification in necrotizing and hypersensitivity vasculitis, are described in this paper. A review of the literature on the the subject is also presented.

    New insights gained through the use of state-of-the-art technologies, including next-generation sequencing, are starting to reveal that the association between the gastrointestinal tract and the resident mycobiota (fungal community) is complex and multifaceted, in which fungi are active participants influencing health and disease. Characterizing the human mycobiome (the fungi and their genome) in healthy individuals showed that the gastrointestinal tract contains 66 fungal genera and 184 fungal species, with Candida as the dominant fungal genera. Although fungi have been associated with a number of gastrointestinal diseases, characterization of the mycobiome has mainly been focused on patients with IBD and graft-versus-host disease. In this Review, we summarize the findings from studies investigating the relationship between the gut mycobiota and gastrointestinal diseases, which indicate that fungi contribute to the aggravation of the inflammatory response, leading to increased disease severity. A model explaining the mechanisms underlying the role of the mycobiota in gastrointestinal diseases is also presented. Our understanding of the contribution of the mycobiota to health and disease is still in its infancy and leaves a number of questions to be addressed. Answering these questions might lead to novel approaches to prevent and/or manage acute as well as chronic gastrointestinal disease.

    Oh, Do-Youn; Bang, Yung-Jue

    2016-01-01

    Human epidermal growth factor receptor 2 (HER2) and HER3 are altered in multiple tumor types, including gastrointestinal cancer. The HER2/HER3 dimer is crucial for HER2-mediated signaling in HER2-positive tumors. HER2-targeting agents, including trastuzumab, lapatinib, trastuzumab emtansine, and pertuzumab, have been approved for the treatment of HER2-positive breast cancer, with trastuzumab also approved for the treatment of HER2-positive gastric cancer. Pertuzumab, a recombinant humanized immunoglobulin (Ig) G1 monoclonal antibody targeting HER-2, binds to the dimerization domain (extracellular domain II) of HER2, which leads to blocking of ligand-induced HER2 heterodimerization. It is under investigation in gastrointestinal cancers, including HER2-positive gastric cancer. In this review, the authors summarize the biology of HER2/HER3 and its alterations in gastrointestinal cancers. The authors focus specifically on the current status of development of pertuzumab in gastrointestinal cancers. The HER2/HER3 alteration in gastrointestinal cancers is quite interesting. In HER2-positive gastric cancer, the dual blockade of HER2 and HER3 using trastuzumab and pertuzumab is being tested in an international phase III trial, the JACOB study. This strategy may benefit HER2-positive gastric cancer patients more as in the case of HER2-positive breast cancer. In other gastrointestinal cancers, including biliary tract cancer, esophageal cancer, pancreatic cancer, and colorectal cancer, there is huge room for the development of pertuzumab.

    Exposure to asbestos is among several factors cited as possible causes of esophageal, gastric and colorectal cancer. More than 45 published studies have presented mortality data on asbestos-exposed workers. For each cohort, we listed the observed and expected rates of deaths from types of gastrointestinal cancer based on the latest published follow-up. Summary standardized mortality ratios (SMRs) were then derived. Finally, we calculated summary SMRs for total gastrointestinal tract cancer for three occupational groups: asbestos factory workers, insulators/shipyard workers and asbestos miners. Statistically significant elevations in summary SMRs were found for esophageal, stomach and total gastrointestinal tract cancer in all asbestos-exposed workers. Esophageal cancer summary SMRs remained significantly elevated when data were reanalyzed to include only those cohorts with death certificate diagnoses for cause of observed deaths. However, summary SMRs were not statistically significant for stomach and total gastrointestinal tract cancer after reanalysis. Summary SMRs by occupational group showed a significant elevation for total gastrointestinal cancer in insulators/shipyard workers. The elevation was not significant after reanalysis. Based on the results after reanalysis, the elevations in summary SMRs for stomach and total gastrointestinal tract cancer are of a magnitude that could result from diagnostic and investigator error. We conclude that more studies are required before stomach and colorectal cancers are documented as asbestos-related diseases. PMID:4036114

    Acute subarachnoid hemorrhage (SAH) is a severe and acute life-threatening cerebrovascular disease. Approximately 80% of all acute non-traumatic SAHs are the result of a ruptured cerebrovascular aneurysm. Despite advances in diagnosis and treatment a high morbidity and mortality still exists. Apart from the primary cerebral damage there are also secondary complications, such as vasospasm, rebleeding, hydrocephalus, cerebral edema or hydrocephalus. For an appropriate therapy an understanding of the extensive pathophysiology, the options in diagnostics and therapy and the complications of the disease are essential. Anesthesiologists are decisively involved in the therapy of the primary and secondary damages and subsequently in the outcome as well. This article provides an overview of the perioperative and intensive care management of patients with SAH.

    Spontaneous intracerebral hemorrhage (ICH) is a particularly severe type of stroke for which no specific treatment has been established yet. Although preclinical models of ICH have substantial methodological limitations, important insight into the pathophysiology has been gained. Mounting evidence suggests an important contribution of inflammatory mechanisms to brain damage and potential repair. Neuroinflammation evoked by intracerebral blood involves the activation of resident microglia, the infiltration of systemic immune cells and the production of cytokines, chemokines, extracellular proteases and reactive oxygen species (ROS). Previous studies focused on innate immunity including microglia, monocytes and granulocytes. More recently, the role of adaptive immune cells has received increasing attention. Little is currently known about the interactions among different immune cell populations in the setting of ICH. Nevertheless, immunomodulatory strategies are already being explored in ICH. To improve the chances of translation from preclinical models to patients, a better characterization of the neuroinflammation in patients is desirable. PMID:25477782

    Ruptured cerebral aneurysm is the most common cause of spontaneous subarachnoid hemorrhage (SAH). Rarely cerebral venous sinus thrombosis (CVST) may present initially as acute SAH, and clinically mimics aneurysmal bleed. We report 2 cases of CVST who presented with severe headache associated with neck pain and focal seizures. Non-contrast brain CT showed SAH, involving the sulci of the convexity of hemisphere (cSAH) without involving the basal cisterns. Both patients received treatment with anticoagulants and improved. Awareness of this unusual presentation of CVST is important for early diagnosis and treatment. The purpose of this paper is to emphasize the inclusion of vascular neuroimaging like MRI with venography or CT venography in the diagnostic workup of SAH, especially in a patient with strong clinical suspicion of CVST or in a patient where neuroimaging showed cSAH.

    There are 4 families of viruses that cause viral hemorrhagic fever (VHF), including Filoviridae. Ebola virus is one virus within the family Filoviridae and the cause of the current outbreak of VHF in West Africa. VHF-endemic areas are found throughout the world, yet traditional diagnosis of VHF has been performed in large reference laboratories centered in Europe and the United States. The large amount of capital needed, as well as highly trained and skilled personnel, has limited the availability of diagnostics in endemic areas except in conjunction with governmental and nongovernmental entities. However, rapid diagnosis of VHF is essential to efforts that will limit outbreaks. In addition, increased global travel suggests VHF diagnoses may be made outside of the endemic areas. Thus, understanding how to diagnose VHF is imperative for laboratories worldwide. This article reviews traditional and current diagnostic modalities for VHF. PMID:26354968

    Duodenal diverticulum is well-known pathologic entity. Most such diverticula are asymptomatic and located on the second stage of the duodenum. The diagnosis is most often established by endoscopy or upper gastrointestinal radiography. Hemorrhage has been described but is an infrequent complication. We report on a patient who presented with massive upper gastrointestinal bleeding, originating from a fourth-stage duodenal diverticulum. The diagnosis was made with a combination of arteriography and scanning with technetium 99-labelled red cells. Diverticulectomy was performed with a successful outcome. This report underlines the diagnostic limits of fiberoptic endoscopy for hemorrhagic lesions located past the third stage of the duodenum. PMID:8956821

    Spontaneous non-traumatic intracerebral hemorrhage (ICH) is associated with high morbidity and mortality throughout the world with no proven effective treatment. Majority of hematoma expansion occur within 4 h after symptom onset and is associated with early deterioration and poor clinical outcome. There is a vital role of ultra-early hemostatic therapy in ICH to limit hematoma expansion. Patients at risk for hematoma expansion are with underlying hemostatic abnormalities. Treatment strategy should include appropriate intervention based on the history of use of antithrombotic use or an underlying coagulopathy in patients with ICH. For antiplatelet-associated ICH, recommendation is to discontinue antiplatelet agent and transfuse platelets to those who will undergo neurosurgical procedure with moderate quality of evidence. For vitamin K antagonist-associated ICH, administration of 3-factor or 4-factor prothrombin complex concentrates (PCCs) rather than fresh frozen plasma to patients with INR >1.4 is strongly recommended. For patients with novel oral anticoagulant-associated ICH, administering activated charcoal to those who present within 2 h of ingestion is recommended. Idarucizumab, a humanized monoclonal antibody fragment against dabigatran (direct thrombin inhibitor) is approved by FDA for emergency situations. Administer activated PCC (50 U/kg) or 4-factor PCC (50 U/kg) to patients with ICH associated with direct thrombin inhibitors (DTI) if idarucizumab is not available or if the hemorrhage is associated with a DTI other than dabigatran. For factor Xa inhibitor-associated ICH, administration of 4-factor PCC or aPCC is preferred over recombinant FVIIa because of the lower risk of adverse thrombotic events. PMID:28360881

    Aflibercept (Ziv-aflibercept, VEGF Trap, AVE005) is an engineered protein that functions as a decoy receptor to bind vascular endothelial growth factor A (VEGF-A). Hemorrhagic events, including epistaxis, gastrointestinal bleeding, and pulmonary bleeding, is one of its major adverse effects, but the incidence rate and overall risk has not been systematically studied. Therefore, we conducted a meta-analysis of published clinical trials to investigate the incidence and relative risk of hemorrhagic events in cancer patients treated with aflibercept. Electronic databases including PubMed, Embase, Cochrane databases, and American Society of Clinical Oncology abstracts were searched. Eligible studies were phase II and III prospective clinical trials of cancer patients treated with aflibercept with toxicity profile on hemorrhagic events. Overall incidence rates, relative risk (RR), and 95 % confidence intervals (CI) were calculated using fixed or random effects models depending on the heterogeneity of the included studies. A total of 4,538 patients with a variety of solid tumors from 13 prospective clinical trials were included for the meta-analysis. The overall incidences of all-grade and high-grade hemorrhagic events in cancer patients were 22.1 % (95 % CI, 16.5-29.7 %) and 4.2 % (95 % CI, 3.9-4.6 %), respectively. The relative risks of hemorrhagic events of aflibercept compared to control were increased for all-grade (RR = 2.63; 95 % CI, 2.07-3.34) and high-grade (RR = 2.45, 95 % CI, 1.62-3.72) hemorrhagic events. The risk of developing high-grade hemorrhagic events with aflibercept was comparable to that of bevacizumab (RR = 1.26; 95 % CI, 0.89-1.79). Aflibercept is associated with an increased risk of developing hemorrhagic events in patients with solid tumors. Close monitoring and management of hemorrhagic events are recommended.

    Acute gastrointestinal bleeding is a common reason for emergency department admissions and an important cause of morbidity and mortality. Factors that complicate its clinical management include patient debility due to comorbidities; intermittence of hemorrhage; and multiple sites of simultaneous bleeding. Its management, therefore, must be multidisciplinary and include emergency physicians, gastroenterologists, and surgeons, as well as radiologists for diagnostic imaging and interventional therapy. Upper gastrointestinal tract bleeding is usually managed endoscopically, with radiologic intervention reserved as an alternative to be used if endoscopic therapy fails. Endoscopy is often less successful in the management of acute lower gastrointestinal tract bleeding, where colonoscopy may be more effective. The merits of performing bowel cleansing before colonoscopy in such cases might be offset by the resultant increase in response time and should be weighed carefully against the deficits in visualization and diagnostic accuracy that would result from performing colonoscopy without bowel preparation. In recent years, multidetector computed tomographic (CT) angiography has gained acceptance as a first-line option for the diagnosis and management of lower gastrointestinal tract bleeding. In selected cases of upper gastrointestinal tract bleeding, CT angiography also provides accurate information about the presence or absence of active bleeding, its source, and its cause. This information helps shorten the total diagnostic time and minimizes or eliminates the need for more expensive and more invasive procedures. © RSNA, 2013.

  13. Analysis of Hemorrhage Volumes After Angiogram-Negative Subarachnoid Hemorrhage.

    Antiplatelet medication use is associated with worsened outcome after angiogram-negative subarachnoid hemorrhage (SAH). It has been hypothesized that these worsened outcomes may be the result of an association between antiplatelet medication use and increased hemorrhage volumes after angiogram-negative SAH. To test this hypothesis, we performed volumetric analysis of computed tomography (CT)-defined hemorrhage after angiogram-negative SAH. This was a retrospective analysis of patients presenting with nontraumatic, angiogram-negative SAH in the Columbia University Subarachnoid Hemorrhage Outcomes database between 2000 and 2013. SAH volumes on admission head CT scans were measured using the MIPAV software package, version 7.20 in a semiautomated fashion. A total of 108 presenting CT scans from patients with angiogram-negative SAH were analyzed. The mean hemorrhage volume was 14.3 mL in the patients with a history of antiplatelet medication use, compared with 6.8 mL in those with no history of antiplatelet use. This difference was found to be significant (P = 0.0029). Antiplatelet medication use is associated with increased SAH volumes in patients with angiogram-negative SAH. Increased hemorrhage volumes may contribute to poor outcomes in this patient population. Prospective studies are warranted to confirm this association. Copyright © 2016 Elsevier Inc.

    1985-07-01

    Exposure to asbestos is among several factors cited as possible causes of esophageal, gastric and colorectal cancer. More than 45 published studies have presented mortality data on asbestos-exposed workers. For each cohort, the authors listed the observed and expected rates of deaths from types of gastrointestinal cancer based on the latest published follow-up. Summary standardized mortality ratios (SMRs) were then derived. Finally, summary SMRs were calculated for total gastrointestinal tract cancer for three occupational groups: asbestos factory workers, insulators/shipyard workers and asbestos miners. Statistically significant elevations in summary SMRs were found for esophageal, stomach and total gastrointestinal tract cancer in all asbestos-exposed workers. Esophageal cancer summary SMR remained significantly elevated when data were reanalyzed to include only those cohorts with death certificate diagnoses for cause of observed deaths. However, summary SMRs were not statistically significant for stomach and total gastrointestinal tract cancer after reanalysis. Summary SMRs by occupational group showed a significant elevation for total gastrointestinal cancer in insulators/shipyard workers. The elevation was not significant after reanalysis. 59 references, 5 tables.

    2011-07-01

    Postpartum hemorrhage remains a major cause of maternal morbidity and mortality. The incidence of postpartum hemorrhage appears to be increasing in developed countries due to an increased number of placenta accreta or percreta after previous Cesarean deliveries. The initial therapy of postpartum hemorrhage consists of uterotonic drugs and inspection of the uterine cavum. At the same time, optimization of the clotting potential should be initiated early. Tranexamic acid may be considered as a first line choice, followed by fibrinogen if necessary. If bleeding continues, fresh frozen plasma and packed red cells should be ordered in a ratio of 1:1, as this ratio has been shown to improve survival in trauma victims. All labor and delivery suites should have standard operating procedures for the management of postpartum hemorrhage in place with regular drills.

    2011-01-01

    Viral hemorrhagic fevers (VHFs) caused by arenaviruses belong to the most devastating emerging human diseases and represent serious public health problems. Arenavirus VHFs in humans are acute diseases characterized by fever and, in severe cases, different degrees of hemorrhages associated with a shock syndrome in the terminal stage. Over the past years, much has been learned about the pathogenesis of arenaviruses at the cellular level, in particular their ability to subvert the host cell's innate antiviral defenses. Clinical studies and novel animal models have provided important new information about the interaction of hemorrhagic arenaviruses with the host's adaptive immune system, in particular virus-induced immunosuppression, and have provided the first hints towards an understanding of the terminal hemorrhagic shock syndrome. The scope of this article is to review our current knowledge on arenavirus VHF pathogenesis with an emphasis on recent developments.

    The authors present a case of monozygotic twins with hereditary hemorrhagic telangiectasia (HHT) who experienced cerebral arteriovenous malformation (AVM) hemorrhage at a very young age. The clinical variables influencing HHT-related AVM rupture are discussed, and questions surrounding the timing of screening and intervention are explored. This is only the second known case of monozygotic HHT twins published in the medical literature, and the youngest pair of first-degree relatives to experience AVM-related cerebral hemorrhage. Evidence guiding the screening and management of familial HHT is lacking, and cases such as this underscore the need for objective and validated protocols.

    Background In 2008 a nosocomial outbreak of five cases of viral hemorrhagic fever due to a novel arenavirus, Lujo virus, occurred in Johannesburg, South Africa. Lujo virus is only the second pathogenic arenavirus, after Lassa virus, to be recognized in Africa and the first in over 40 years. Because of the remote, resource-poor, and often politically unstable regions where Lassa fever and other viral hemorrhagic fevers typically occur, there have been few opportunities to undertake in-depth study of their clinical manifestations, transmission dynamics, pathogenesis, or response to treatment options typically available in industrialized countries. Methods and Findings We describe the clinical features of five cases of Lujo hemorrhagic fever and summarize their clinical management, as well as providing additional epidemiologic detail regarding the 2008 outbreak. Illness typically began with the abrupt onset of fever, malaise, headache, and myalgias followed successively by sore throat, chest pain, gastrointestinal symptoms, rash, minor hemorrhage, subconjunctival injection, and neck and facial swelling over the first week of illness. No major hemorrhage was noted. Neurological signs were sometimes seen in the late stages. Shock and multi-organ system failure, often with evidence of disseminated intravascular coagulopathy, ensued in the second week, with death in four of the five cases. Distinctive treatment components of the one surviving patient included rapid commencement of the antiviral drug ribavirin and administration of HMG-CoA reductase inhibitors (statins), N-acetylcysteine, and recombinant factor VIIa. Conclusions Lujo virus causes a clinical syndrome remarkably similar to Lassa fever. Considering the high case-fatality and significant logistical impediments to controlled treatment efficacy trials for viral hemorrhagic fever, it is both logical and ethical to explore the use of the various compounds used in the treatment of the surviving case reported here

  2. Gastrointestinal Stent Update

    PubMed Central

    2010-01-01

    The use of self-expanding metallic stents in the upper gastrointestinal tract, placed under radiologic imaging or endoscopic guidance, is the current treatment of choice for the palliation of malignant gastrointestinal outlet obstructions. Advances in metallic stent design and delivery systems have progressed to the stage where this treatment is now considered a minimally invasive therapy. Metallic stent placement will broaden further into the field of nonsurgical therapy for the gastrointestinal tract. To date, metallic stents placed in the esophagus, gastric outlet, colorectum, and bile ducts are not intended to be curative, but rather to provide a palliative treatment for obstructions. The evolution of metallic stent technology will render such procedures not only palliative but also therapeutic, by enabling local drug delivery, and the use of biodegradable materials will reduce procedure-related complications.

    Dengue fever, a very old disease, has reemerged in the past 20 years with an expanded geographic distribution of both the viruses and the mosquito vectors, increased epidemic activity, the development of hyperendemicity (the cocirculation of multiple serotypes), and the emergence of dengue hemorrhagic fever in new geographic regions. In 1998 this mosquito-borne disease is the most important tropical infectious disease after malaria, with an estimated 100 million cases of dengue fever, 500,000 cases of dengue hemorrhagic fever, and 25,000 deaths annually. The reasons for this resurgence and emergence of dengue hemorrhagic fever in the waning years of the 20th century are complex and not fully understood, but demographic, societal, and public health infrastructure changes in the past 30 years have contributed greatly. This paper reviews the changing epidemiology of dengue and dengue hemorrhagic fever by geographic region, the natural history and transmission cycles, clinical diagnosis of both dengue fever and dengue hemorrhagic fever, serologic and virologic laboratory diagnoses, pathogenesis, surveillance, prevention, and control. A major challenge for public health officials in all tropical areas of the world is to devleop and implement sustainable prevention and control programs that will reverse the trend of emergent dengue hemorrhagic fever.

  6. Diffuse Alveolar Hemorrhage

    2013-01-01

    Diffuse alveolar hemorrhage (DAH) is a life-threatening and medical emergency that can be caused by numerous disorders and presents with hemoptysis, anemia, and diffuse alveolar infiltrates. Early bronchoscopy with bronchoalveolar lavage is usually required to confirm the diagnosis and rule out infection. Most cases of DAH are caused by capillaritis associated with systemic autoimmune diseases such as anti-neutrophil cytoplasmic antibody-associated vasculitis, anti-glomerular basement membrane disease, and systemic lupus erythematosus, but DAH may also result from coagulation disorders, drugs, inhaled toxins, or transplantation. The diagnosis of DAH relies on clinical suspicion combined with laboratory, radiologic, and pathologic findings. Early recognition is crucial, because prompt diagnosis and treatment is necessary for survival. Corticosteroids and immunosuppressive agents remain the gold standard. In patients with DAH, biopsy of involved sites can help to identify the cause and to direct therapy. This article aims to provide a general review of the causes and clinical presentation of DAH and to recommend a diagnostic approach and a management plan for the most common causes. PMID:23678356

    2017-01-01

    Spontaneous non-traumatic intracerebral hemorrhage (ICH) remains a significant cause of mortality and morbidity throughout the world. To improve the devastating course of ICH, various clinical trials for medical and surgical interventions have been conducted in the last 10 years. Recent large-scale clinical trials have reported that early intensive blood pressure reduction can be a safe and feasible strategy for ICH, and have suggested a safe target range for systolic blood pressure. While new medical therapies associated with warfarin and non-vitamin K antagonist oral anticoagulants have been developed to treat ICH, recent trials have not been able to demonstrate the overall beneficial effects of surgical intervention on mortality and functional outcomes. However, some patients with ICH may benefit from surgical management in specific clinical contexts and/or at specific times. Furthermore, clinical trials for minimally invasive surgical evacuation methods are ongoing and may provide positive evidence. Upon understanding the current guidelines for the management of ICH, clinicians can administer appropriate treatment and attempt to improve the clinical outcome of ICH. The purpose of this review is to help in the decision-making of the medical and surgical management of ICH. PMID:28178413

    Machupo virus, the cause of Bolivian hemorrhagic fever, is a highly lethal viral hemorrhagic fever with no Food and Drug Administration-approved vaccines or therapeutics. This study evaluated the guinea pig as a model using the Machupo virus-Chicava strain administered via aerosol challenge. Guinea pigs (Cavia porcellus) were serially sampled to evaluate the temporal progression of infection, gross and histologic lesions, and sequential changes in serum chemistry and hematology. The incubation period was 5 to 12 days, and complete blood counts revealed leukopenia with lymphopenia and thrombocytopenia. Gross pathologic findings included congestion and hemorrhage of the gastrointestinal mucosa and serosa, noncollapsing lungs with fluid exudation, enlarged lymph nodes, and progressive pallor and friability of the liver. Histologic lesions consisted of foci of degeneration and cell death in the haired skin, liver, pancreas, adrenal glands, lymph nodes, tongue, esophagus, salivary glands, renal pelvis, small intestine, and large intestine. Lymphohistiocytic interstitial pneumonia was also present. Inflammation within the central nervous system, interpreted as nonsuppurative encephalitis, was histologically apparent approximately 16 days postexposure and was generally progressive. Macrophages in the tracheobronchial lymph node, on day 5 postexposure, were the first cells to demonstrate visible viral antigen. Viral antigen was detected throughout the lymphoid system by day 9 postexposure, followed by prominent spread within epithelial tissues and then brain. This study provides insight into the course of Machupo virus infection and supports the utility of guinea pigs as an additional animal model for vaccine and therapeutic development.

  9. Circulatory contributors to the phenotype in hereditary hemorrhagic telangiectasia

    PubMed Central

    Shovlin, Claire L.

    2015-01-01

    Hereditary hemorrhagic telangiectasia (HHT) is mechanistically and therapeutically challenging, not only because of the molecular and cellular perturbations that generate vascular abnormalities, but also the modifications to circulatory physiology that result, and are likely to exacerbate vascular injury. First, most HHT patients have visceral arteriovenous malformations (AVMs). Significant visceral AVMs reduce the systemic vascular resistance: supra-normal cardiac outputs are required to maintain arterial blood pressure, and may result in significant pulmonary venous hypertension. Secondly, bleeding from nasal and gastrointestinal telangiectasia leads to iron losses of such magnitude that in most cases, diet is insufficient to meet the ‘hemorrhage adjusted iron requirement.’ Resultant iron deficiency restricts erythropoiesis, leading to anemia and further increases in cardiac output. Low iron levels are also associated with venous and arterial thromboses, elevated Factor VIII, and increased platelet aggregation to circulating 5HT (serotonin). Third, recent data highlight that reduced oxygenation of blood due to pulmonary AVMs results in a graded erythrocytotic response to maintain arterial oxygen content, and higher stroke volumes and/or heart rates to maintain oxygen delivery. Finally, HHT-independent factors such as diet, pregnancy, sepsis, and other intercurrent illnesses also influence vascular structures, hemorrhage, and iron handling in HHT patients. These considerations emphasize the complexity of mechanisms that impact on vascular structures in HHT, and also offer opportunities for targeted therapeutic approaches. PMID:25914716

    Upper gastrointestinal hemorrhage secondary to gastric varices still has a high death rate. Fourteen patients were admitted to our unit with bleeding gastric varices from November 1989 to August 1991. Endoscopic injection sclerotherapy obtained control of the bleeding in 92.3%; however, recurrences occurred in 33% of these cases in the first 24-48 hours, with a death rate of 50% during the second stage of the upper gastrointestinal hemorrhage. Total mortality rate was 21.4%. Of the fourteen patients, nine exhibited junctional varices, while five hand fundic varices. In ten of the fourteen patients, gastric varices developed during esophageal sclerotherapy. While hospitalized, it was observed that patients with gastric varices in the fundus had more recurrences and mortality, than those located next to the cardio-esophageal junction. Sclerosis of the varices only obtained temporary control of the bleeding with greater frequency of recurrences and mortality.

    Hereditary hemorrhagic telangiectasia (HHT), also known by the eponym Osler–Weber–Rendu syndrome, is a group of related disorders inherited in an autosomal dominant fashion and characterized by the development of arteriovenous malformations (AVM) in the skin, mucous membranes, and/or internal organs such as brain, lungs, and liver. Its prevalence is currently estimated at one in 5,000 to 8,000. Most cases are due to mutations in the endoglin (HHT1) or ACVRLK1 (HHT2) genes. Telangiectasias in nasal and gastrointestinal mucosa generally present with recurrent/chronic bleeding and iron deficiency anemia. Larger AVMs occur in lungs (~40%–60% of affected individuals), liver (~40%–70%), brain (~10%), and spine (~1%). Due to the devastating and potentially fatal complications of some of these lesions (for example, strokes and brain abscesses with pulmonary AVMs), presymptomatic screening and treatment are of utmost importance. However, due to the rarity of this condition, many providers lack an appreciation for the whole gamut of its manifestations and complications, age-dependent penetrance, and marked intrafamilial variation. As a result, HHT remains frequently underdiagnosed and many families do not receive the appropriate screening and treatments. This article provides an overview of the clinical features of HHT, discusses the clinical and genetic diagnostic strategies, and presents an up-to-date review of literature and detailed considerations regarding screening for visceral AVMs, preventive modalities, and treatment options.

    Introduction. The main adverse effect of anticoagulant therapy is bleeding, and major bleeding, including intracranial, gastrointestinal, and retroperitoneal bleeding, has been reported as an adverse effect of edoxaban, a direct oral anticoagulant (DOAC). Bleeding during systemic anticoagulation with edoxaban presents a therapeutic conundrum, because there is currently no safe or efficacious reversal agent to stop major bleeding. Case Report. A 51-year-old woman had multiple traumatic injuries, including lower limb fractures. On day 8, she developed deep venous thrombosis, and edoxaban was administered orally. On day 38, she developed fungemia, which was treated with an antifungal drug. On day 43, she presented with dyspnea. Chest computed tomography scan showed bilateral diffuse ground-glass opacities in the whole lung fields. The results of the subsequent workup (i.e., serum levels of the antineutrophil cytoplasmic antibody, antinuclear antibody, and antiglomerular basement membrane antibody) and microbiological study were unremarkable. Based on these findings, her condition was diagnosed as diffuse alveolar hemorrhage (DAH) associated with edoxaban therapy. The lung opacities disappeared spontaneously after edoxaban therapy was discontinued. Conclusion. DAH is a dangerous complication associated with edoxaban therapy. DOACs, including edoxaban, should be prescribed with caution, especially for patients in a critical condition. PMID:27872767

    Fecal bile acid patterns for the Apollo 17 flight were studied to determine the cause of diarrhea on the mission. The fecal sterol analysis gave no indication of an infectious diarrhea, or specific, or nonspecific etiology occurring during the entire flight. It is assumed that the gastrointestinal problems encountered are the consequences of altered physiology, perhaps secondary to physical or emotional stress of flight.

    Gastrointestinal endoscopy has a major diagnostic and therapeutic role in most gastrointestinal disorders; however, limited information is available about clinical efficacy and safety in pregnant patients. The major risks of endoscopy during pregnancy include potential harm to the fetus because of hypoxia, premature labor, trauma and teratogenesis. In some cases, endoscopic procedures may be postponed until after delivery. When emergency or urgent indications are present, endoscopic procedures may be considered with some precautions. United States Food and Drug Administration category B drugs may be used in low doses. Endoscopic procedures during pregnancy may include upper gastrointestinal endoscopy, percutaneous endoscopic gastrostomy, sigmoidoscopy, colonoscopy, enteroscopy of the small bowel or video capsule endoscopy, endoscopic retrograde cholangiopancreatography and endoscopic ultrasonography. All gastrointestinal endoscopic procedures in pregnant patients should be performed in hospitals by expert endoscopists and an obstetrician should be informed about all endoscopic procedures. The endoscopy and flexible sigmoidoscopy may be safe for the fetus and pregnant patient, and may be performed during pregnancy when strong indications are present. Colonoscopy for pregnant patients may be considered for strong indications during the second trimester. Although therapeutic endoscopic retrograde cholangiopancreatography may be considered during pregnancy, this procedure should be performed only for strong indications and attempts should be made to minimize radiation exposure.

    We experienced three cases of postoperative hemorrhage from a stapled gastrointestinal anastomosis, and established endoscopic microwave coagulation therapy (EMCT) with a cylinder-type electrode. We were able to treat postoperative hemorrhage over the entire circumference of stapled anastomosis successfully. Two patients had undergone a lower third thoracic esophagogastrectomy through a left thoraco-abdominal approach for gastric cancer in the cardia, while the other case had undergone Billroth I gastrectomy. They each had fresh bleeding from the stapled anastomosis after the operation. Emergency endoscopic examination was immediately performed. Endoscopy revealed bleeding on the suture line. We performed hemostasis endoscopically with microwave coagulation therapy safely. They were discharged from the hospital without complications such as leakage and stenosis. Since EMCT with the cylinder-type electrode can coagulate shallowly and widely, it is very effective for hemorrhage from a stapled anastomosis.

    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.

    Heterotopic pancreas is a relatively common variant of foregut embryologic dystopia that can be described as pancreatic tissue found outside the normal anatomic location, being independent from vascular supply of normal pancreas. Having all features of pancreatic tissue except for the major duct structures, this ectopic tissue may be clinically recognized when pathologic changes take place. Inflammation, hemorrhagic or obstructive states, and eventually malignancy-related problems may become a diagnostic challenge for clinician and finally lead to consequences of misdiagnosis. In this article we will discuss a case of heterotopic pancreatic tissue located in gastric cardia, which was diagnosed preoperatively as gastrointestinal stromal tumor. PMID:25785332

  2. Aneurysmal Subarachnoid Hemorrhage

    PubMed Central

    2015-01-01

    Aneurysmal subarachnoid hemorrhage (SAH) is a worldwide health burden with high fatality and permanent disability rates. The overall prognosis depends on the volume of the initial bleed, rebleeding, and degree of delayed cerebral ischemia (DCI). Cardiac manifestations and neurogenic pulmonary edema indicate the severity of SAH. The International Subarachnoid Aneurysm Trial (ISAT) reported a favorable neurological outcome with the endovascular coiling procedure compared with surgical clipping at the end of 1 year. The ISAT trial recruits were primarily neurologically good grade patients with smaller anterior circulation aneurysms, and therefore the results cannot be reliably extrapolated to larger aneurysms, posterior circulation aneurysms, patients presenting with complex aneurysm morphology, and poor neurological grades. The role of hypothermia is not proven to be neuroprotective according to a large randomized controlled trial, Intraoperative Hypothermia for Aneurysms Surgery Trial (IHAST II), which recruited patients with good neurological grades. Patients in this trial were subjected to slow cooling and inadequate cooling time and were rewarmed rapidly. This methodology would have reduced the beneficial effects of hypothermia. Adenosine is found to be beneficial for transient induced hypotension in 2 retrospective analyses, without increasing the risk for cardiac and neurological morbidity. The neurological benefit of pharmacological neuroprotection and neuromonitoring is not proven in patients undergoing clipping of aneurysms. DCI is an important cause of morbidity and mortality following SAH, and the pathophysiology is likely multifactorial and not yet understood. At present, oral nimodipine has an established role in the management of DCI, along with maintenance of euvolemia and induced hypertension. Following SAH, hypernatremia, although less common than hyponatremia, is a predictor of poor neurological outcome. PMID:25272066

    Postpartum hemorrhage remains the number one cause of maternal death globally despite the fact that it is largely a preventable and most often a treatable condition. While the global problem is appreciated, some may not realize that in the United States postpartum hemorrhage is a leading cause of mortality and unfortunately, the incidence is on the rise. In New York, obstetric hemorrhage is the second leading cause of maternal mortality in the state. National data suggests that hemorrhage is disproportionally overrepresented as a contributor to severe maternal morbidity and we suspect as we explore further this will be true in New York State as well. Given the persistent and significant contribution to maternal mortality, it may be useful to analyze the persistence of this largely preventable cause of death within the framework of the historic "Three Delays" model of maternal mortality. The ongoing national and statewide problem with postpartum hemorrhage will be reviewed in this context of delays in an effort to inform potential solutions.

  5. Reactionary Hemorrhage in Gynecological Surgery

    Background: Bleeding is a major complication in contemporary gynecological surgery. We discusses this rare, albeit potentially serious, unexpected complication. The authors mean by “reactionary,” hemorrhage that occurs within the first 24 hours after surgery. More or less, all gynecological surgeons have had to deal with this situation at some stage of their career. The seriousness of this complication stems from the fact that often the surgeon is not in the immediate vicinity to promptly step in and treat the patient. Nevertheless, the key to successful management is prompt diagnosis, immediate resuscitation, and operative intervention. Methods: By using the collective hospital database, we reviewed 719 patient records. The authors operated on these patients between November 1990 and March 2007 (inclusive) in one hospital, Royal Brisbane and Women's Hospital, the main teaching hospital in Brisbane, Queensland, Australia. The procedures performed in the 719 patients comprised 476 vaginal hysterectomies and 243 laparoscopic hysterectomies. Both public and private patients were included. The objective of the review was to establish the incidence of postoperative reactionary hemorrhage following the initial operation, as defined by the number of patients returning to the operating theatre (OT) because of postoperative hemorrhage within 24 hours of the initial hysterectomy. Results: Of the 719 patients, 6 experienced reactionary postoperative hemorrhage, 3 each in the vaginal hysterectomy and laparoscopic hysterectomy groups. That would make the incidence of postoperative reactionary hemorrhage 0.6% in the vaginal hysterectomy and 1.2% in the laparoscopic hysterectomy group. None of these 6 patients had any preoperative hemorrhagica diatheses. There was neither ureteric, bladder, intestinal, nor any other injuries in the whole series. No long-term complications or mortalities occurred. Conclusion: Reactionary postoperative hemorrhage is a rare, albeit serious

    Ebola and Marburg viruses cause a severe viral hemorrhagic fever disease mainly in Sub-Saharan Africa. Although outbreaks are sporadic, there is the potential for filoviruses to spread to other continents unintentionally because of air travel or intentionally because of bioterrorism. This article discusses the natural history, epidemiology, and clinical presentation of patients infected with Ebola and Marburg viruses. Clinicians in the United States should be aware of the symptoms of these viral infections in humans and know the appropriate procedures for contacting local, state, and national reference laboratories in the event of a suspected case of filoviral hemorrhagic fever.

    Choroidal fissure cysts are often incidentally discovered. They are usually asymptomatic. The authors report a case of growing and hemorrhagic choroidal fissure cyst which was treated surgically. A 22-year-old female presented with headache. Cranial MRI showed a left-sided choroidal fissure cyst. Follow-up MRI showed that the size of the cyst had increased gradually. Twenty months later, the patient was admitted to our emergency department with severe headache. MRI and CT showed an intracystic hematoma. Although such cysts usually have a benign course without symptoms and progression, they may rarely present with intracystic hemorrhage, enlargement of the cyst and increasing symptomatology.

    Hemorrhage in regions remote from the site of initial intracranial operations is rare, but does occur. We report three cases of cerebellar hemorrhage that developed after supratentorial surgery, all of which had similar clinical findings and CT images. The first case was a 37-year-old man with a craniopharyngioma in the suprasellar lesion. Partial removal of the tumor was performed through frontal craniotomy and the translaminaterminals approach. A large quantity of cerebospinal fluid (CSF) was suctioned from the third ventricle during the operation, resulting in marked brain shrinkage. The second and third cases were 34- and 51-year-old women with unruptured right middle cerebral aneurysms. Clipping of the aneurysms through the pterional approach was performed in both cases. In the second case, CSF was suctioned in large quantity from the carotid and prechiasmal cistern at the operation, resulting in marked brain shrinkage. In the third case, however, only a small volume of CSF was suctioned from the carotid and prechiasmal cistern during the operation, and no marked brain shrinkage was observed. CT scan showed that the hematomas were located mainly in the subdural or the subarachnoid spaces over the cerebellar hemisphere and partially extending into the cerebellar cortex. The mechanism of cerebellar hemorrhage in these series of patients was thought to be multifactorial. The possible etiology for cerebellar hemorrhage in the three cases presented was examined, including the role of CSF suction during surgery and disturbance of venous circulation in the posterior fossa. Suction of the CSF may cause intracranial hypotension. Further reduction of intracranial pressure leads to an increased transluminal venous pressure. There was no episode of hypertension or disturbed blood coagulation during or after the operation. The preoperative angiogram also revealed no abnormality at the region of the posterior fossa.

    Sheehan's syndrome is described as panhypopituitarism secondary to a pituitary hypoperfusion during or just after obstetric hemorrhage. Advances in obstetric care make this syndrome quite unusual, but some cases are reported in underdeveloped countries. Clinical presentation may change depending on the severity of the hormone deficiencies. The diagnosis is clinical, but abnormalities are observed in the magnetic resonance in up to 70% of patients. We present a case of a woman with hypotension, hypothermia and edemas in relation to a previous massive postpartum hemorrhage. Failure in lactation was the clue to the diagnosis. A review of its main features, its diagnosis and treatment in the current literature is also presented.

    The bacterial colonisation is established immediately after birth, through direct contact with maternal microbiota, and may be influenced during lactation. There is emerging evidence indicating that quantitative and qualitative changes on gut microbiota contribute to alterations in the mucosal activation of the immune system, leading to intra- or extra-intestinal diseases. A balance between pathogenic and beneficial microbiota throughout childhood and adolescence is important to gastrointestinal health, including protection against pathogens, inhibition of pathogens, nutrient processing (synthesis of vitamin K), stimulation of angiogenesis, and regulation of host fat storage. Probiotics can promote an intentional modulation of intestinal microbiota favouring the health of the host. A review is presented on the modulation of intestinal microbiota on prevention, and adjuvant treatment of some paediatric gastrointestinal diseases.

    Obesity usually is associated with morbidity related to diabetes mellitus and cardiovascular diseases. However, there are many gastrointestinal and hepatic diseases for which obesity is the direct cause (eg, nonalcoholic fatty liver disease) or is a significant risk factor, such as reflux esophagitis and gallstones. When obesity is a risk factor, it may interact with other mechanisms and result in earlier presentation or complicated diseases. There are increased odds ratios or relative risks of several gastrointestinal complications of obesity: gastroesophageal reflux disease, erosive esophagitis, Barrett's esophagus, esophageal adenocarcinoma, erosive gastritis, gastric cancer, diarrhea, colonic diverticular disease, polyps, cancer, liver disease including nonalcoholic fatty liver disease, cirrhosis, hepatocellular carcinoma, gallstones, acute pancreatitis, and pancreatic cancer. Gastroenterologists are uniquely poised to participate in the multidisciplinary management of obesity as physicians caring for people with obesity-related diseases, in addition to their expertise in nutrition and endoscopic interventions.

    Twenty-five percent of the world's population could be suffering parasitic infestation. Highest prevalence is in underdeveloped agricultural and rural areas in the tropical and subtropical regions. In some areas incidence may reach 90% of the population. In contrast, some major economic projects intended to promote local development have, paradoxically, caused parasitic proliferation, e.g. bilharziasis in Egypt and Sudan and Chagas disease in Brazil. The commonest cosmopolitan gastrointestinal parasite is Entamoeba histolytica. Some intestinal parasite are endemic in temperate climates, e.g. Entrobius vermicularis. The AIDS epidemic has increased the prevalence and severity of parasitic disease, particularly Strongyloides stercolaris. Tropical parasites are seen in Western people who travel to tropical countries. Radiology has acquired a major role in diagnosis and management of gastrointestinal parasite infestations and their complications.

    Gastrointestinal stromal tumor has received a lot of attention over the last 10 years due to its unique biologic behavior, clinicopathological features, molecular mechanisms, and treatment implications. GIST is the most common mesenchymal neoplasm in the gastrointestinal tract and has emerged from a poorly understood and treatment resistant neoplasm to a well-defined tumor entity since the discovery of particular molecular abnormalities, KIT and PDGFRA gene mutations. The understanding of GIST biology at the molecular level promised the development of novel treatment modalities. Diagnosis of GIST depends on the integrity of histology, immunohistochemistry and molecular analysis. The risk assessment of the tumor behavior relies heavily on pathological evaluation and significantly impacts clinical management. In this review, historic review, epidemiology, pathogenesis and genetics, diagnosis, role of molecular analysis, prognostic factor and treatment strategies have been discussed. PMID:22943011

  1. Gastrointestinal food allergies.

    PubMed

    Heine, Ralf G

    2015-01-01

    Gastrointestinal food allergies present during early childhood with a diverse range of symptoms. Cow's milk, soy and wheat are the three most common gastrointestinal food allergens. Several clinical syndromes have been described, including food protein-induced enteropathy, proctocolitis and enterocolitis. In contrast with immediate, IgE-mediated food allergies, the onset of gastrointestinal symptoms is delayed for at least 1-2 hours after ingestion in non-IgE-mediated allergic disorders. The pathophysiology of these non-IgE-mediated allergic disorders is poorly understood, and useful in vitro markers are lacking. The results of the skin prick test or measurement of the food-specific serum IgE level is generally negative, although low-positive results may occur. Diagnosis therefore relies on the recognition of a particular clinical phenotype as well as the demonstration of clear clinical improvement after food allergen elimination and the re-emergence of symptoms upon challenge. There is a significant clinical overlap between non-IgE-mediated food allergy and several common paediatric gastroenterological conditions, which may lead to diagnostic confusion. The treatment of gastrointestinal food allergies requires the strict elimination of offending food allergens until tolerance has developed. In breast-fed infants, a maternal elimination diet is often sufficient to control symptoms. In formula-fed infants, treatment usually involves the use an extensively hydrolysed or amino acid-based formula. Apart from the use of hypoallergenic formulae, the solid diets of these children also need to be kept free of specific food allergens, as clinically indicated. The nutritional progress of infants and young children should be carefully monitored, and they should undergo ongoing, regular food protein elimination reassessments by cautious food challenges to monitor for possible tolerance development.

    Crimean-Congo Hemorrhagic Fever (CCHF) is a disease transmitted by the Crimean-Congo hemorrhagic fever virus (CCHFV), characterized by severe fever and hemorrhage and with a reported fatality level of 3-30%. Cerebral hemorrhage, gastrointestinal hemorrhage, severe anemia, shock, myocardial infarction, pulmonary edema, and pleural effusion may be seen as causes of death. Cardiac troponin T (cTn-T) is a biochemical marker with high sensitivity and specificity in myocardial injury. The purpose of this study was to determine the prognostic significance of serum troponin T levels in CCHF patients. Patients hospitalized with a diagnosis of CCHF and whose serum cTn-T was investigated were examined retrospectively. Patients were divided into two groups on the basis of presence or absence of hemorrhage. Data were subjected to statistical analysis. One hundred thirty-five CCHF patients and 72 control subjects were included. Hemorrhage was present in 48 (35.6%) patients. Mean serum cTn-T level was 17.3 ± 28.0 ng/L in the patients with hemorrhage, 9.98 ± 5.97 ng/L in the non-hemorrhage patients (P = 0.001) and 6.6P = 2.6 ng/L in the control samples (P < 0.001). At a cTn-T level cut-off point of 9 ng/L, area under the ROC curve was 0.797 (95%CI: 0.730-0.854), sensitivity 83.0%, specificity 87.5%, PPD 95.7%, and NPV 60.3%. At logistic regression analysis, a rise in cTn-T level above 14 ng/L increased the probability of hemorrhage in CCHF patients approximately threefold. An increased troponin T level may be a prognostic risk factor for hemorrhage in CCHF patients. This marker should therefore be borne in mind in determining treatment strategy in these patients. J.

    Bilateral adrenal hemorrhage with subsequent adrenal insufficiency is a recognized complication of anticoagulant therapy. Because the clinical manifestations are often nonspecific, the antemortem diagnosis of adrenal hemorrhage has been a difficult clinical problem. Computed tomography (CT) provides detailed images of the adrenal glands that are not possible with conventional imaging methods. The CT findings of bilateral adrenal hemorrhage in an anticoagulated patient are reported.

    Convulsive and nonconvulsive seizures frequently complicate acute brain injury particularly central nervous system hemorrhages and both have been associated with poor outcome. No randomized controlled trials have been conducted to guide decisions on seizure prophylaxis or treatment. The magnitude of additional injury from nonconvulsive seizures remains controversial and some argue that these epileptiform patterns primarily represent surrogate markers of severely injured brain. The deleterious effects of seizures on brain recovering from a recent injury have to be weighed against the deleterious effects of antiepileptic medications when making decisions on prophylaxis and treatment. Currently seizure prophylaxis is not generally recommended for patients with spontaneous intracerebral hemorrhage (ICH) or aneurysmal subarachnoid hemorrhage (aSAH). However, short-term prophylaxis (during the acute critical illness) is commonly instituted for patients in whom seizures would likely lead to additional injury such as herniation or rebleeding. ICH or aSAH patients with seizures at the onset of their hemorrhage, patients with ICH in close proximity to the cortical surface, and aSAH patients with a poor clinical grade (poor neurologic examination and/or thick cisternal blood) are at high risk of seizures, especially nonconvulsive, and are frequently kept on short-term prophylaxis. Convulsive seizures occur in 7% to 17% of patients with spontaneous ICH and in between 6% and 26% of those with aneurysmal aSAH. These should be treated as soon as possible regardless of the underlying causative factors. Nonconvulsive seizures are seen in about 20% of patients with ICH and in 8% to 18% of those with aSAH. It is controversial how aggressively to treat nonconvulsive seizures. Convulsive and nonconvulsive seizures are frequent after central nervous system hemorrhage and treatment is controversial, particularly for nonconvulsive seizures. Randomized controlled trials need to be

    Argon plasma coagulation (APC) is a new method of non-contact electrocoagulation in which current is applied to tissues by means of ionised argon gas (argon plasma). The development of special applicators has made this method applicable for gastrointestinal endoscopy. The primary indication for APC is the treatment of hemorrhage in the gastrointestinal tract. APC has been proven to be highly effective and easily used, with clear advantages over previously used methods. This article describes the introduction of APC in Slovenia and the first experiences with this method in the clinical department of internal medicine in Maribor.

    Acute lower gastrointestinal hemorrhage is an uncommon and severe symptom. The overall mortality rate ranges from 5 to 12 percent and can approach 40 percent for persistent or recurring bleedings. We report a case of a patient with severe recurrent lower bleeding in whom, despite several repeated explorations and a blind subtotal colectomy, no lesion could be found. Multiple (n = 4) leveled stomas of the small bowel with succus entericus reinfusion were required to localize and treat the cause of the bleeding. This case report is followed by a review of the literature of the management of lower gastrointestinal bleeding.

    Hemorrhagic myelopathy or myelomalacia is an uncommon cause of failure to stand after general anesthesia. Affected horses are usually young and have been anesthetized for relatively short times in dorsal recumbency. Clinical signs involve the hind limbs and include loss of deep pain perception. Etiology of this condition is not known. Differentiation from other forms of neuropathy and myopathy is important to the prognosis.

    Hereditary hemorrhagic telangiectasia is an inherited autosomal dominant disease presenting with recurrent bleeding episodes and iron deficiency anemia due to vascular malformations. Hereditary hemorrhagic telangiectasia is associated with an increased risk of stroke, gastrointestinal bleeding and pulmonary hypertension and life expectancy is significantly reduced. Excess vascular endothelial growth factor (VEGF) plays a key role in the pathophysiology of the disease. Here we report about a male patient with hereditary hemorrhagic telangiectasia presenting with pulmonary and central nervous system involvement experiencing repetitive nosebleeds, necessitating frequent local cauterization and transfusion of more than 100 units of packed red blood cells. After initiation of temporary therapy with the anti-VEGF antibody bevacizumab at a dosage of 1 mg/kg body weight every 2 weeks, the nose bleeding episodes and the epistaxis severity score significantly decreased and long-lasting transfusion independence was achieved. Reinitiation of low-dose bevacizumab after relapse again proved effective without any documented therapy-related adverse events. In comparison to other reported anti-VEGF antibody protocols in hereditary hemorrhagic telangiectasia, our treatment approach proved to be cost-efficient. Intermittent low-dose therapy with bevacizumab represents an effective and cost-efficient treatment option for transfusion-dependent patients with hereditary hemorrhagic telangiectasia.

  10. New Insights into Nonvitamin K Antagonist Oral Anticoagulants' Reversal of Intracerebral Hemorrhage.

    2015-01-01

    The nonvitamin K antagonist oral anticoagulants (NOACs) dabigatran, rivaroxaban, apixaban, and edoxaban are associated with an equal or lower incidence of stroke and systemic embolism and a much lower incidence of intracranial hemorrhage and hemorrhagic stroke than warfarin is, without the need for routine laboratory monitoring. However, reversal strategies are not currently established in the case of NOAC-related hemorrhagic stroke. In emergency situations, well-defined management for NOAC-related hemorrhagic stroke may improve clinical outcomes. Thus, in this chapter, general measures initially required to prevent the expansion of intracerebral hematomas, charcoal administration to reduce NOAC absorption from the gastrointestinal tract, application of hemodialysis to remove dabigatran, and coagulation factor therapy including 4-factor prothrombin complex concentrate and recombinant activated factor VII are reviewed. The specific reversal agents idarucizumab, which is a monoclonal antibody against dabigatran; andexanet alfa, a recombinant human factor Xa decoy for Xa inhibitors; and PER977, a small synthetic molecule for reversal of both Xa and thrombin inhibitors, are currently under development. These agents will facilitate the clinical management of NOAC-associated hemorrhagic stroke and other severe bleeding.

  11. Familial perimesencephalic subarachnoid hemorrhage: two case reports

    PubMed Central

    2014-01-01

    Introduction Non-aneurysmal spontaneous subarachnoid hemorrhage is characterized by an accumulation of a limited amount of subarachnoid hemorrhage, predominantly around the midbrain, and a lack of blood in the brain parenchyma or ventricular system. It represents 5% of all spontaneous subarachnoid hemorrhage cases. In spite of extensive investigation, understanding of the mechanisms leading to perimesencephalic non-aneurysmal subarachnoid hemorrhage remains incompletely defined. A growing body of evidence has supported a familial predisposition for non-aneurysmal spontaneous subarachnoid hemorrhage. Case presentation A 39-year-old Caucasian man presented with sudden onset headache associated with diplopia. His computed tomography scan revealed perimesencephalic subarachnoid hemorrhage. A cerebral angiogram showed no apparent source of bleeding. He was treated conservatively and discharged after 1 week without any neurological deficits. The older brother of the first case, a 44-year-old Caucasian man, presented 1.5 years later with acute onset of headache and his computed tomography scan also showed perimesencephalic non-aneurysmal subarachnoid hemorrhage. He was discharged home with normal neurological examination 1 week later. Follow-up angiograms did not reveal any source of bleeding in either patient. Conclusions We report the cases of two siblings with perimesencephalic non-aneurysmal subarachnoid hemorrhage, which may further suggest a familial predisposition of non-aneurysmal spontaneous subarachnoid hemorrhage and may also point out the possible higher risk of perimesencephalic non-aneurysmal subarachnoid hemorrhage in the first-degree relatives of patients with perimesencephalic non-aneurysmal subarachnoid hemorrhage.

    Intracerebral hemorrhage after spinal surgery is a rare but dreaded complication. The most commonly described form of intracranial hemorrhage after spinal surgery is remote cerebellar hemorrhage (i.e. anatomically distant from the surgical site) (Brockmann MA, Groden C. Remote cerebellar hemorrhage: a review. The Cerebellum 2006;5:64-8); however subdural, subarachnoid, and intraventricular hemorrhage can also occur in combination or isolated (Kaloostian PE, Kim JE, Bydon A, Sciubba DM, Wolinsky JP, Gokaslan ZL, Witham TF. Intracranial hemorrhage after spine surgery. J Neurosurg Spine 2013;19:370-80; Khalatbari MR, Khalatbari J, Moharamzad Y. Intracranial hemorrhage following lumbar spine surgery. Eur Spine J 2012;21:2092-96). Isolated intraventricular hemorrhage after spinal surgery is extremely rare; to our knowledge, there are only two cases reported in the literature (Kaloostian PE, Kim JE, Bydon A, Sciubba DM, Wolinsky JP, Gokaslan ZL, Witham TF.

    Hemorrhagic stroke which consists of subarachnoid hemorrhage and intracerebral hemorrhage is a dominant cause of death and disability worldwide. Although great efforts have been made, the physiological mechanisms of these diseases are not fully understood and effective pharmacological interventions are still lacking. Melatonin (N-acetyl-5-methoxytryptamine), a neurohormone produced by the pineal gland, is a broad-spectrum antioxidant and potent free radical scavenger. More importantly, there is extensive evidence demonstrating that melatonin confers neuroprotective effects in experimental models of hemorrhagic stroke. Multiple molecular mechanisms such as antioxidant, anti-apoptosis, and anti-inflammation, contribute to melatonin-mediated neuroprotection against brain injury after hemorrhagic stroke. This review article aims to summarize current knowledge regarding the beneficial effects of melatonin in experimental models of hemorrhagic stroke and explores the underlying mechanisms. We propose that melatonin is a promising neuroprotective candidate that is worthy of further evaluation for its potential therapeutic applications in hemorrhagic stroke.

    In clinical descriptions of human plague, fever and tender lymphadenitis are emphasized and gastrointestinal manifestations are rarely mentioned. A review of 71 human plague cases showed that gastrointestinal symptoms occurred commonly (57%). Vomiting (39%) was the most frequent symptom, with nausea (34%), diarrhea (28%) and abdominal pain (17%) occurring less often. Physicians treating patients who reside in or have recently visited plague-endemic areas should include plague in the differential diagnosis in the presence of gastrointestinal symptoms and fever.

    2011-07-01

    The rapid growth of molecular genetics and its attendant germline mutation discoveries has enabled identification of persons who are at an inordinately high cancer risk and, therefore, ideal candidates for prevention. However, one must fully appreciate the extensive genotypic and phenotypic heterogeneity that exists in hereditary cancer. Once the causative germline mutation has been identified in a patient, high-risk members of the family can be similarly tested and identified and provided highly targeted surveillance and management opportunities. DNA testing can change the individual's presumed risk status and affect decision making by patients and their physicians regarding surveillance and management. Our purpose is to describe familial/hereditary cancers of the gastrointestinal tract, including familial Barrett's esophagus, hereditary diffuse gastric cancer, gastrointestinal stromal tumors, familial adenomatous polyposis and desmoid tumors, Lynch syndrome, small bowel cancer, and familial pancreatic cancer. We use our discussion of Lynch syndrome as a model for diagnostic and clinical translation strategies for all hereditary gastrointestinal tract cancers, which clearly can then be extended to cancer of all anatomic sites. Highly pertinent questions from the patient's perspective include the following: What kind of counseling will be provided to a patient with a Lynch syndrome mutation, and should that counseling be mandatory? Does the proband have the responsibility to inform relatives about the familial mutation, even if the relatives do not want to know whether they carry it? Is the patient is responsible for notifying family members that a parent or sibling has Lynch syndrome? Can notification be forced and, if so, under what circumstances? These questions point out the need for criteria regarding which family members to inform and how to inform them.

    A variety of endoscopic haemostatic techniques have enabled major advances in the management of not only bleeding peptic ulcers and bleeding varices, but also in a variety of bleeding lesions in the small intestine and in the colon. Indeed, the development and widespread implementation of endoscopic haemostasis has been one of the most important developments in clinical gastroenterology in the past two decades. An increasingly ageing cohort of patients with multiple co-morbidity are being treated and therefore improving the outcome of gastrointestinal bleeding continues to pose major challenges.

    Cystic fibrosis has historically been considered a pulmonary disease, but with the increasing life expectancy of these patients, gastrointestinal manifestations are becoming more important. Furthermore, nutritional status is closely linked to pulmonary function and, thus, overall mortality. This article discusses gastrointestinal manifestations (which involve nutritional, pancreatic, hepatobiliary, and, in particular, gastrointestinal tract issues) of cystic fibrosis as well as management of the disease. In addition, the article discusses studies that have been critical to our understanding of gastrointestinal manifestations of cystic fibrosis. PMID:27330503

    Carcinoid tumors are low-grade malignant tumors that arise from neuroendocrine cells. Primary renal carcinoid tumors are extremely uncommon. A 63-year-old woman presented with a right abdominal mass and fever. Abdominal computed tomography demonstrated a mass in the right kidney; the mass measured 120 mm in diameter and showed hemorrhage. The patient underwent an uneventful right radical nephrectomy, and histological appearance was typical of carcinoid tumor. Immunohistochemistry demonstrated strong cytoplasmic labeling for neuron-specific enolase and synaptophysin. Additional examinations of the gastrointestinal tract did not show any evidence of carcinoid tumors. The patient remains free from disease recurrence at 8 months after the operation. The prognosis for primary renal carcinoid tumor is relatively optimistic. Complete surgical excision is the only recommended treatment for localized renal carcinoid tumor.

    The diagnosis-related-groups (DRG) is the cost-based system for hospital reimbursement. However, the proceeds does not coincide with the costs. Aim of the study was to identify the profit, which we could gained with 147, 155, 158, 162, 165, 198 gastrointestinal surgery DRG. 30 consecutive patients, undergone to surgery in Clinica Chirurgica of L'Aquila University, had been studied. We had calculated the daily costs of medical and nursing practice, diagnostic tests, drugs, hospitalization, surgical instruments for every patient's therapy. The DRG-proceeds had been correlated with the DRG-costs. The "major gastrointestinal surgery" had not profit (147 DRG: anterior resection of rectum = -354428 Pounds, Miles = -94020 Pounds; 155 DRG: total gastrectomy = -1920641 Pounds). On the contrary, "minimal surgery" had good profits (158 DRG: hemorroidectomy with local anestesia = 1469605 Pounds;162 DRG: sutureless groin hernioplasty = 1561200 Pounds; 198 DRG: videolaparochole-cystectomy: 1208807 Pounds). The study seems to demonstrate the disparity of the reimbursement system related to DRG. However, the surgeons, as managers, must employ warily the resources for producing DRG.

    The "chronology of cancer" is a concept that describes the nature of cancers through the measure of time. The field extends from carcinogenesis to development, progression, and metastasis. Carcinogenesis is a multi-step process, which results from the accumulation of multiple genetic or epigenetic alterations. Various chronologies of gastrointestinal cancers have been reported for carcinogenesis caused by different risk factors. These chronologies are useful for developing cancer prevention strategies. The tumor growth rate is one of the most important factors in this field. Combining the factors of time and tumor growth enables us to estimate the time at which cancer or metastasis occurred, retrospectively, and to predict the survival of cancer patients, prospectively. It is noteworthy that these chronologies differ significantly among individual cases, even of cancers derived from the same organ. Thus, they are useful for individualization. We can apply the knowledge obtained in this field to the basic research and the diagnosis and treatment of cancers. The chronology of cancer is a classical but interesting field, which helps us consider and explore the essence of cancer. We review the topics related to the chronology of gastrointestinal cancer, ranging from carcinogenesis to metastasis.

  1. Gastrointestinal physiology and functions.

    PubMed

    Schneeman, Barbara O

    2002-11-01

    While the health benefit of a functional food may be a metabolic response that lowers risk for disease, the actual target for the food or food component may be on the functioning of the gastrointestinal tract (GIT). For example, slowing absorption from the intestine, as measured by examining the appearance of the nutrient or food component in the blood, the hormone response associated with absorption of the compound or excretion of the compound, may provide a health benefit. However, the food component may slow absorption by delaying gastric emptying, altering the mixing within the intestinal contents or decreasing the availability of digestive enzymes in the intestine. These measures of GIT function provide validation of the mechanisms by which the functional food or food components affect metabolism. Bioavailability of physiologically active compounds from foods will be determined by the digestibility of foods that contain these compounds, their subsequent absorption and utilization by tissues. The physical structure of foods contributes to the functional effects of foods as well as to the availability of compounds from foods. For example, recent studies have demonstrated that changing the viscosity of the gut contents alters absorption and GIT response. Additionally, food structures such as the plant cell wall change the availability of absorbable compounds along the gastrointestinal contents. The areas of probiotics and prebiotics have highlighted the potential importance of gut microflora in health. While evidence suggests biological activity relevant to disease risk reduction, the long-term implications of the microbial activity have yet to be established.

    Crimean-Congo hemorrhagic fever virus (CCHFV) is a member of the Bunyaviridae family and Nairovirus genus. The viral genome consists of 3 RNA segments of 12 kb (L), 6.8 kb (M), and 3 kb (S). Crimean-Congo hemorrhagic fever (CCHF) is the most widespread tickborne viral infection worldwide: it has been reported in many regions of Africa, the Middle East, and Asia. The geographical distribution of CCHFV corresponds most closely with the distribution of members of the tick genera, and Hyalomma ticks are the principal source of human infection. In contrast to human infection, CCHFV infection is asymptomatic in all species. Treatment options for CCHF are limited; immunotherapy and ribavirin are effective in the treatment of CCHF; the efficacy of ribavirin in the treatment of CCHF has not yet been proven. This article reviews the history, epidemiology, clinical symptoms, pathogenesis, diagnosis, and treatment of CCHFV, as well as the development of a vaccine against it.

    Acute Hemorrhagic Edema of Infancy is a small vessel leucocytoclastic vasculitis affecting young infants. It is characterized by large, target-like, macular to purpuric plaques predominantly affecting the face, ear lobes and extremities. Non-pitting edema of the distal extremities and low-grade fever may also be present. Extra-cutaneous involvement is very rare. Although the lesions have a dramatic onset in a twenty-four to forty-eight hour period, usually the child has a non-toxic appearance. In most cases there are no changes in laboratory parameters. The cutaneous biopsy reveals an inflammatory perivascular infiltrate. It is a benign and auto-limited disease, with complete resolution within two to three weeks leaving no sequelae in the majority of cases. No recurrences are described. We report a case of a 42-day old girl admitted at our hospital with Acute Hemorrhagic Edema of Infancy.

    Postpartum hemorrhage is defined by bleeding > 500 mL through the vagina. It is one of the obstetrical complications that obstetricians fear most. It is the leading cause of maternal mortality in the world, especially in developing countries. The reference treatments in France are parenteral oxytocin and sulprostone. Sulprostone involves sometimes fatal side effects, and must be administered only in appropriate health care facilities. It also has the major disadvantage of requiring refrigeration. Misoprostol has uterotonic properties that have led to its occasional off-label use in the treatment of postpartum hemorrhage, by rectal or sublingual administration, as an alternative to sulprostone. A careful review of the literature on this particular use of misoprostol is essential.

    Hemorrhage of the kidneys and adrenal glands has many etiologies. In the adrenal glands, trauma, anticoagulation, stress, sepsis, surgery, and neoplasms are common causes of hemorrhage. In the kidneys, reasons for hemorrhage include trauma, bleeding diathesis, vascular diseases, infection, infarction, hemorrhagic cyst rupture, the Antopol-Goldman lesion, and neoplasms. Angiomyolipoma and renal cell carcinoma are the neoplasms most commonly associated with hemorrhage in the kidneys and adrenal cortical carcinoma, metastases, and pheochromocytoma are associated with hemorrhage in the adrenal glands. Understanding the computed tomography and magnetic resonance imaging features, and causes of hemorrhage in the kidneys and adrenal glands is critical. It is also important to keep in mind that mimickers of hemorrhage exist, including lymphoma in both the kidneys and adrenal glands, and melanoma metastases in the adrenal glands. Appropriate imaging follow-up of renal and adrenal hemorrhage should occur to exclude an underlying malignancy as the cause. If there is suspicion for malignancy that cannot be definitively diagnosed on imaging, surgery or biopsy may be warranted. Angiography may be indicated when there is a suspected underlying vascular disease. Unnecessary intervention, such as nephrectomy, may be avoided in patients with benign causes or no underlying disease. Appropriate management is dependent on accurate diagnosis of the cause of renal or adrenal hemorrhage and it is incumbent upon the radiologist to determine the etiology.

    The aim of this study was to assess the incidence and contributing factors of hypophosphatemia and the association with poor long-term outcome after nontraumatic intracranial hemorrhage. This was a prospective, observational study of patients with nontraumatic intracranial hemorrhage (i.e., aneurysmal or perimesencephalic subarachnoid hemorrhage, or spontaneous intracerebral or intraventricular hemorrhage) treated in the intensive care unit (ICU) at our university hospital. Plasma phosphate concentrations were measured serially in 2-day sections during the 6 day study period. The ICU mortality was recorded, 3-month and 1-year outcomes were assessed using the Glasgow Outcome Scale. One hundred patients were enrolled. The frequency of hypophosphatemia (Pi ≤ 0.65 mmol/l) was 70%. Chronic hypertension, acute hydrocephalus, and diffuse brain edema were more common in patients with hypophosphatemia compared with normophosphatemics (44% vs. 21%, P = 0.021; 59% vs. 33%, P = 0.021; and 43% vs. 13%, P = 0.004, respectively). Hypophosphatemic patients had higher maximum SOFA scores [10 (7-11) vs. 7.5 (5.75-10), P = 0.024]. Initial phosphate concentration correlated inversely with APACHE II score on admission (ρ = -0.304, P = 0.002) and SOFA score on the first ICU day (ρ = -0.269, P = 0.008). There was no difference in outcome between hypophosphatemic and normophosphatemic patients. In all five patients with severe hypophosphatemia (Pi < 0.32 mmol/l) the functional outcome was good. Hypophosphatemia was common in this patient population. The outcome was similar between hypophosphatemic and normophosphatemic patients. Chronic hypertension, acute hydrocephalus, diffuse brain edema and higher SOFA scores were more common in patients with hypophosphatemia. © 2017 The Acta Anaesthesiologica Scandinavica Foundation.

    Hereditary hemorrhagic telangiectasia (HHT) is a rare autosomal-dominantly inherited disease that occurs in approximately one in 5000 to 8000 people. Clinical diagnosis of HHT is made when a person presents three of the following four criteria: family history, recurrent nosebleeds, mucocutaneous telangiectasis, and arteriovenous malformations (AVM) in the brain, lung, liver and gastrointestinal (GI) tract. Although epistaxis is the most common presenting symptom, AVMs affecting the lungs, brain and GI tract provoke a more serious outcome. Heterozygous mutations in endoglin, activin receptor-like kinase 1 (ACVRL1; ALK1), and SMAD4, the genes involved in the transforming growth factor-β family signaling cascade, cause HHT. We report here the case of a 63 year-old male patient who presented melena and GI bleeding episodes, proven to be caused by bleeding from multiple gastric angiodysplasia. Esophagogastroduodenoscopy revealed multiple angiodysplasia throughout the stomach. Endoscopic argon plasma coagulation was performed to control bleeding from a gastric angiodysplasia. The patient has been admitted several times with episodes of hemoptysis and hematochezia. One year ago, the patient was hospitalized due to right-sided weakness, which was caused by left basal ganglia hemorrhage as the part of HHT presentation. In family history, the patient's mother and elder sister had died, due to intracranial hemorrhage, and his eldest son has been suffered from recurrent epistaxis for 20 years. A genetic study revealed a mutation in exon 3 of ALK1 (c.199C > T; p.Arg67Trp) in the proband and his eldest son presenting epistaxis.

    A 20-year-old woman with a 2-year history of histologically confirmed palmoplantar keratoderma due to psoriasis, resistant to several topical agents, was admitted to the Department of Dermatology, Uludag University, Bursa, Turkey. Therapy with oral acitretin (0.5 mg/kg/day, 35 mg/day) was initiated. A month after starting acitretin treatment, she noted slight reddening of the second left fingernail. Clinical examination revealed red-brown discoloration of the second fingernail associated with subungual hemorrhage involving the proximal nail bed (lunula region) (Fig. 1). The nail change was asymptomatic. The patient complained only of discoloration underneath the nail plate. No abnormalities were detected on the skin, mucous membranes, or toenails/other fingernails. The patient denied exposure to microtrauma or any other drugs. The erythrocyte sedimentation rate, full blood cell count, electrolytes, renal and hepatic tests, and serum lipids were normal. Coagulation tests, including blood clotting time, international normalized ratio, activated partial thromboplastin time, thrombin time, platelet number, and function tests, were within normal levels. Treatment with acitretin was discontinued, and the nail change resolved completely after 3 weeks. A similar episode of subungual hemorrhage recurred, however, within 48 h after re-challenge with a lower dose of acitretin (25 mg/day). The drug was definitively stopped and the eruption faded again within a week. An objective causality assessment suggests that subungual hemorrhage was probably related to acitretin in this patient.

    Objective Acute aneurysmal subarachnoid hemorrhage (SAH) is a complex multifaceted disorder that plays out over days to weeks. Many SAH patients are seriously ill and require a prolonged ICU stay. Cardiopulmonary complications are common. The management of SAH patients focuses on the anticipation, prevention and management of these secondary complications. Data Sources Source data were obtained from a PubMed search of the medical literature. Data Synthesis and Conclusion The rupture of an intracranial aneurysm is a sudden devastating event with immediate neurologic and cardiac consequences that require stabilization to allow for early diagnostic angiography. Early complications include rebleeding, hydrocephalus, and seizures. Early repair of the aneurysm (within 1-3 days) should take place by surgical or endovascular means. Over the first 1-2 weeks after hemorrhage, patients are at risk for delayed ischemic deficits due to vasospasm, autoregulatory failure and intravascular volume contraction. Delayed ischemia is treated with combinations of volume expansion, induced hypertension, augmentation of cardiac output, angioplasty and intra-arterial vasodilators. Subarachnoid hemorrhage is a complex disease with a prolonged course that can be particularly challenging and rewarding to the intensivist. PMID:19114880

    There are studies reporting primary headaches to be associated with gastrointestinal disorders, and some report resolution of headache following the treatment of the associated gastrointestinal disorder. Headache disorders are classified by The International Headache Society as primary or secondary; however, among the secondary headaches, those attributed to gastrointestinal disorders are not appreciated. Therefore, we aimed to review the literature to provide evidence for headaches, which originate from the gastrointestinal system. Gastrointestinal disorders that are reported to be associated with primary headaches include dyspepsia, gastro esophageal reflux disease (GERD), constipation, functional abdominal pain, inflammatory bowel syndrome (IBS), inflammatory bowel disorders (IBD), celiac disease, and helicobacter pylori (H. Pylori) infection. Some studies have demonstrated remission or improvement of headache following the treatment of the accompanying gastrointestinal disorders. Hypotheses explaining this association are considered to be central sensitization and parasympathetic referred pain, serotonin pathways, autonomic nervous system dysfunction, systemic vasculopathy, and food allergy. Traditional Persian physicians, namely Ebn-e-Sina (Avicenna) and Râzi (Rhazes) believed in a type of headache originating from disorders of the stomach and named it as an individual entity, the "Participatory Headache of Gastric Origin". We suggest providing a unique diagnostic entity for headaches coexisting with any gastrointestinal abnormality that are improved or cured along with the treatment of the gastrointestinal disorder.

  13. Gastrointestinal hormones regulating appetite

    PubMed Central

    Chaudhri, Owais; Small, Caroline; Bloom, Steve

    2006-01-01

    The role of gastrointestinal hormones in the regulation of appetite is reviewed. The gastrointestinal tract is the largest endocrine organ in the body. Gut hormones function to optimize the process of digestion and absorption of nutrients by the gut. In this capacity, their local effects on gastrointestinal motility and secretion have been well characterized. By altering the rate at which nutrients are delivered to compartments of the alimentary canal, the control of food intake arguably constitutes another point at which intervention may promote efficient digestion and nutrient uptake. In recent decades, gut hormones have come to occupy a central place in the complex neuroendocrine interactions that underlie the regulation of energy balance. Many gut peptides have been shown to influence energy intake. The most well studied in this regard are cholecystokinin (CCK), pancreatic polypeptide, peptide YY, glucagon-like peptide-1 (GLP-1), oxyntomodulin and ghrelin. With the exception of ghrelin, these hormones act to increase satiety and decrease food intake. The mechanisms by which gut hormones modify feeding are the subject of ongoing investigation. Local effects such as the inhibition of gastric emptying might contribute to the decrease in energy intake. Activation of mechanoreceptors as a result of gastric distension may inhibit further food intake via neural reflex arcs. Circulating gut hormones have also been shown to act directly on neurons in hypothalamic and brainstem centres of appetite control. The median eminence and area postrema are characterized by a deficiency of the blood–brain barrier. Some investigators argue that this renders neighbouring structures, such as the arcuate nucleus of the hypothalamus and the nucleus of the tractus solitarius in the brainstem, susceptible to influence by circulating factors. Extensive reciprocal connections exist between these areas and the hypothalamic paraventricular nucleus and other energy-regulating centres of the

    Gastrointestinal bleeding represents a common medical emergency, with considerable morbidity and mortality rates, and a prompt diagnosis is essential for a better prognosis. In such a context, endoscopy is the main diagnostic tool; however, in cases where the gastrointestinal hemorrhage is massive, the exact bleeding site might go undetected. In addition, a trained professional is not always present to perform the procedure. In an emergency setting, optical colonoscopy presents limitations connected with the absence of bowel preparation, so most of the small bowel cannot be assessed. Scintigraphy cannot accurately demonstrate the anatomic location of the bleeding and is not available at emergency settings. The use of capsule endoscopy is inappropriate in the acute setting, particularly in the emergency department at night, and is a highly expensive method. Digital angiography, despite its high sensitivity, is invasive, presents catheterization-related risks, in addition to its low availability at emergency settings. On the other hand, computed tomography angiography is fast, widely available and minimally invasive, emerging as a promising method in the diagnostic algorithm of these patients, being capable of determining the location and cause of bleeding with high accuracy. Based on a critical literature review and on their own experience, the authors propose a computed tomography angiography protocol to assess the patient with gastrointestinal bleeding. PMID:26811556

  16. Effective treatment of gastrointestinal bleeding with thalidomide - Chances and limitations

    2016-01-01

    For more than 50 years bleeding from gastrointestinal angiodysplasias has been treated by hormonal therapy with estrogens and progesterons. After a randomized study finally demonstrated that hormones have no effect on bleeding events and transfusion requirements, therapy has switched to endoscopic coagulation. However, angiodysplasias tend to recur over months to years and endoscopy often has to be repeated for long time periods. Thalidomide, which caused severe deformities in newborn children in the 1960s, is now increasingly used after it was shown to suppress tumor necrosis factor alpha, inhibit angiogenesis and to be also effective for treatment of multiple myeloma. In 2011 thalidomide was proven to be highly effective for treatment of bleeding from gastrointestinal angiodysplasias in a randomized study. Further evidence by uncontrolled studies exists that thalidomide is also useful for treatment of bleeding in hereditary hemorrhagic telangiectasia. In spite of this data, endoscopic therapy remains the treatment of choice in many hospitals, as thalidomide is still notorious for its teratogenicity. However, patients with gastrointestinal bleeding related to angiodysplasias are generally at an age in which women have no child-bearing potential. Teratogenicity is therefore no issue for these elderly patients. Other side-effects of thalidomide like neurotoxicity may limit treatment options but can be monitored safely. PMID:27003992

    The reactivation of varicella-zoster virus occurs in immunocompromised patients, especially in cases of hematological malignancy. Disseminated reactivation could involve digestive tract with life-threatening condition. A 76-year-old woman, with a history of chronic lymphocytic leukemia, presented with left hypochondrium pain, and a vesicular rash with hemorrhagic shock that revealed an hemorrhagic gastritis due to varicella-zoster virus. The literature review identified 28 additional cases of gastrointestinal mucosal damage during reactivation of varicella-zoster virus. Mortality is 40%. We report here the first case in the course of low-grade lymphoid malignancy. Acute gastrointestinal symptoms in immunocompromised patients should evoke a varicella-zoster virus reactivation with gastrointestinal involvement. This clinical manifestation, although rare, should not be ignored because of its severity. Copyright © 2013 Société nationale française de médecine interne (SNFMI). Published by Elsevier SAS.

    Gastrointestinal (GI) cancer, including gastric and colorectal cancer, is a major cause of death worldwide. A substantial proportion of patients with GI cancer have a familial history, and several causative genes have been identified. Gene carriers with these hereditary GI syndromes often harbor several kinds of cancer at an early age, and genetic testing and specific surveillance may save their lives through early detection. Gastroenterologists and GI surgeons should be familiar with these syndromes, even though they are not always associated with a high penetrance of GI cancer. In this review, we provide an overview and discuss the diagnosis, genetic testing, and management of four major hereditary GI cancers: familial adenomatous polyposis, Lynch syndrome, hereditary diffuse gastric cancer, and Li-Fraumeni syndrome.

    Motility disorders were previously impossible to penetrate, but new technics have made it possible to investigate these disorders. An overview of neurophysiological functions of the gastrointestinal tract is given, and various conditions representing primary and secondary motility disorders are discussed. Diagnostic procedures and treatment options are presented. The clinical picture of such disorders is demonstrated by two cases. A girl born in 1995, having megacystis microcolon hypoperistalsis syndrome was the first Norwegian individual to have an intestinal transplantation, which was performed in London, UK. A girl with hypoganglionosis is also reported. Since May 1998, manometry of the oesophagus was performed in 44 children, and pathological findings were demonstrated in 18 of these patients. The motoric activity of the stomach was investigated in 17 patients using two-dimensional ultrasound and electrogastrography pre- and post-prandially. Disturbed function was found in nine of these children. Anorectal manometry was performed in 147 individuals, and Hirschsprung's disease was diagnosed in four.

    The recent development of advanced sequencing techniques has revealed the complexity and diverse functions of the gut microbiota. Furthermore, alterations in the composition or balance of the intestinal microbiota, or dysbiosis, are associated with many gastrointestinal diseases. The looming question is whether dysbiosis is a cause or effect of these diseases. In this review, we will evaluate the contribution of intestinal microbiota in obesity, fatty liver, inflammatory bowel disease, and irritable bowel syndrome. Promising results from microbiota or metabolite transfer experiments in animals suggest the microbiota may be sufficient to reproduce disease features in the appropriate host in certain disorders. Less compelling causal associations may reflect complex, multi-factorial disease pathogenesis, in which dysbiosis is a necessary condition. Understanding the contributions of the microbiota in GI diseases should offer novel insight into disease pathophysiology and deliver new treatment strategies such as therapeutic manipulation of the microbiota.

    Gastrointestinal infections in children are a major cause of morbidity and mortality worldwide. Children living in developing countries are particularly susceptible to infectious diarrhea because of poor standards of hygiene and sanitation. Although the magnitude of diarrheal illnesses in developed countries is less, costly hospital admissions are still frequent. The causal agent of infectious diarrhea is most frequently related to age, geographical location, lifestyle habits, use of antibiotics, associated medical conditions, social circumstances, and degree of immune competence. In this article we present some of the most important articles published in the field during the last year. The role of Helicobacter pylori in the pathogenesis of gastritis and peptic ulcer disease has been shown in adults and children. Information about the natural history of H. pylori, symptomatology, and diagnostic therapeutic approaches for children are being generated constantly; we discuss some of the most relevant information in this review.

    Viral hemorrhagic fever (VHF) is defined as virus infections that usually cause pyrexia and hemorrhagic symptoms with multiple organ failure. VHF includes following viral infections: Ebola hemorrhagic fever (EHF), Marburg hemorrhagic fever (MHF), Crimean-Congo hemorrhagic fever (CCHF) and Lassa fever. In particular, the causative agents of EHF, MHF, CCHF, and Lassa fever are Ebola, Marburg, CCHF, Lassa viruses, respectively, and regarded as biosafety level-4 pathogens because of their high virulence to humans. Recently, relatively large outbreaks of EHF and MHF have occurred in Africa, and areas of EHF- and MHF-outbreaks seem to be expanding. Although outbreaks of VHF have not been reported in Japan, there is a possibility that the deadly hemorrhagic fever viruses would be introduced to Japan in future. Therefore, preparedness for possible future outbreaks of VHF is necessary in areas without VHF outbreaks.

  3. Disorders of gastrointestinal hypomotility

    Bielefeldt, Klaus; Tuteja, Ashok; Nusrat, Salman

    2016-01-01

    Ingestion and digestion of food as well as expulsion of residual material from our gastrointestinal tract requires normal propulsive, i.e. motor, function. Hypomotility refers to inherited or acquired changes that come with decreased contractile forces or slower transit. It not only often causes symptoms but also may compromise nutritional status or lead to other complications. While severe forms, such as pseudo-obstruction or ileus, may have a tremendous functional impact, the less severe forms of hypomotility may well be more relevant, as they contribute to common disorders, such as functional dyspepsia, gastroparesis, chronic constipation, and irritable bowel syndrome (IBS). Clinical testing can identify changes in contractile activity, defined by lower amplitudes or abnormal patterns, and the related effects on transit. However, such biomarkers show a limited correlation with overall symptom severity as experienced by patients. Similarly, targeting hypomotility with pharmacological interventions often alters gut motor function but does not consistently improve symptoms. Novel diagnostic approaches may change this apparent paradox and enable us to obtain more comprehensive information by integrating data on electrical activity, mechanical forces, patterns, wall stiffness, and motions with information of the flow of luminal contents. New drugs with more selective effects or more specific delivery may improve benefits and limit adverse effects. Lastly, the complex regulation of gastrointestinal motility involves the brain-gut axis as a reciprocal pathway for afferent and efferent signaling. Considering the role of visceral input in emotion and the effects of emotion on visceral activity, understanding and managing hypomotility disorders requires an integrative approach based on the mind-body continuum or biopsychosocial model of diseases.

    Light stand photography with direct illumination of the retina is a common method of demonstrating retinal hemorrhages. The lack of contrast between dark hemorrhages and surrounding dark retina, and the difficulty of photographing into the concavity of an eye limit this technique. Transillumination of a bivalved globe with a bright external light source such as a colonoscope or microscope light yields high contrast superior photographs. This technique is useful to document retinal hemorrhages, and provides quality photographs for courtroom demonstrations.

    Brunner's gland adenoma is an extremely rare benign small bowel neoplasm, often discovered incidentally during upper gastrointestinal endoscopy or radiological diagnostics. In few cases, it tends to cause gastrointestinal hemorrhage or intestinal obstruction. We report here our experience with a 47-year-old woman with a Brunner's gland adenoma of more than 6 cm in size, located in the first part of the duodenum and causing gastrointestinal bleeding. Initially, we performed a partial endoscopic resection using endoloop and snare alternatively to prevent severe bleeding. A rest endoscopic polypectomy with the submucosal dissection technique was planned. However, on request of the patient, an elective surgical duodenotomy with submucosal resection of the remaining small duodenal tumor was performed. To better define the patient's characteristics and treatment options of such lesions, we performed a systematic review of the available literature in PubMed. Recently, an endoscopic removal is being increasingly practiced and is considered as a safe treatment modality of such lesions. PMID:28203131

    Abstract Adrenal hemorrhage (AH) is a rare but life-threatening condition. Small focal hemorrhage may present subclinically, but massive hemorrhage may lead to rapid cardiovascular collapse and ultimately death if not diagnosed appropriately and treated quickly. Most cases reported in the literature have been treated conservatively. In an event of increasing hemorrhage during conservative management, it may be tricky to intervene surgically because of the hematoma around the gland. Here we describe a case where we managed a large spontaneous AH by a combination of angioembolization and laparoscopic adrenalectomy. PMID:27579389

    Shoulder dystocia and postpartum hemorrhage represent two of the most common emergencies faced in obstetric clinical practice, both requiring prompt recognition and management to avoid significant morbidity or mortality. Shoulder dystocia is an uncommon, unpredictable, and unpreventable obstetric emergency and can be managed with appropriate intervention. Postpartum hemorrhage occurs more commonly and carries significant risk of maternal morbidity. Institutional protocols and algorithms for the prevention and management of shoulder dystocia and postpartum hemorrhage have become mainstays for clinicians. The goal of this review is to summarize the diagnosis, incidence, risk factors, and management of shoulder dystocia and postpartum hemorrhage. Copyright © 2017 Elsevier Inc. All rights reserved.

    Spontaneous adrenal hemorrhage (SAH) is a serious medical condition associated with variable clinical presentation depending on the extent of the hemorrhage. Pregnancy-induced adrenal hemorrhage is poorly understood. A low cortisol level in the peripartum period with radiological findings is sufficient to establish the diagnosis. Prompt hormone replacement and supportive care to ensure good clinical outcomes is crucial. Due to the potentially life-threatening complications, physicians should have a high suspicion for adrenal hemorrhage when they evaluate patients with hypotension, fatigue, and abdominal pain during the peripartum period.

    Background Variceal hemorrhage is associated with high morbidity and mortality. A balloon tamponade device (BTD), such as the Sengstaken-Blakemore or Minnesota tube, may be used in cases of variceal hemorrhage. While these devices may be effective at controlling acute bleeding, the effect on patient outcomes remains less clear. We sought to describe the number of patients with variceal hemorrhage and a BTD who survive to discharge, survive to one-year, and develop complications related to a BTD. Methods In this retrospective study, we identified patients at a single, tertiary care center who underwent placement of a BTD for upper gastrointestinal hemorrhage between 2003 and 2014. Patient characteristics and outcomes were summarized using descriptive statistics. Results 34 patients with a BTD were identified. Median age was 57.5 (IQR 47–63) and 76% (26/34) were male. Approximately 59% (20/34) of patients survived to discharge, and 41% (13/32) were alive after one year. Two patients were lost to follow-up. Of those surviving to discharge, 95% (19/20) had undergone transjugular intrahepatic portosystemic shunt (TIPS), while 36% (5/14) of patients who did not survive to discharge had TIPS (p < 0.01). One complication, an esophageal perforation, was identified and managed conservatively. Conclusion In this cohort of patients undergoing BTD placement for variceal hemorrhage, approximately 59% of patients were alive at discharge and 41% were alive after one year. Placement of a BTD as a temporizing measure in the management of acute variceal hemorrhage may be helpful, particularly when utilized as a bridge to more definitive therapy. PMID:28460805

    The University HealthSystem Consortium (UHC), a national hospital engagement network (HEN), establishes health-system metrics to assess and improve quality of care. In 2012, a metric for inpatient anticoagulant hemorrhage was developed. The utility of this metric to improve anticoagulation care has not been assessed. To identify opportunities to improve anticoagulation safety through the use of a HEN metric for inpatient anticoagulant-associated hemorrhage. This was a single-center, retrospective, observational study of metric identified patients with presumed inpatient anticoagulant hemorrhage. Records were reviewed to confirm anticoagulant hemorrhage and identify bleed site and severity. A structured process was used to assess bleed preventability and subsequently identify opportunities for improving care. Each bleed was reviewed by 2 investigators. Anticoagulant hemorrhage was confirmed in 85.9% (61/71) with heparin infusion the most common anticoagulant. Patients were primarily medical, with a mean age of 72.7 ± 15 years. The most common bleed sites were gastrointestinal (24.6%) and retroperitoneal (21.3%). Major bleeding occurred in 60.7% (37/61). Anticoagulant hemorrhage was preventable in 18% (11/61) of cases with heparin protocol noncompliance the most common cause of a preventable bleed. Several opportunities for improving heparin infusion therapy were recognized and protocol changes were implemented. The UHC metric accurately captures inpatient anticoagulant-associated hemorrhage the majority of time. The UHC metric on anticoagulant-associated hemorrhage can be a useful part of a health system's overall plan for the safe use of anticoagulants in the hospital setting. © The Author(s) 2015.

  16. Autistic disorder and gastrointestinal disease.

    Autistic disorder is a pervasive developmental disorder manifested in the first 3 years of life by dysfunction in social interaction and communication. Many efforts have been made to explore the biologic basis of this disorder, but the etiology remains unknown. Recent publications describing upper gastrointestinal abnormalities and ileocolitis have focused attention on gastrointestinal function and morphology in these children. High prevalence of histologic abnormalities in the esophagus, stomach, small intestine and colon, and dysfunction of liver conjugation capacity and intestinal permeability were reported. Three surveys conducted in the United States described high prevalence of gastrointestinal symptoms in children with autistic disorder. Treatment of the digestive problems may have positive effects on their behavior.

    Background In the critically ill, mineralocorticoid deficiency (MD) is associated with greater disease severity, the development of acute renal insufficiency, and increased mortality. We hypothesized that severely injured trauma patients presenting with hemorrhagic shock would demonstrate a high degree of MD. We also hypothesized that MD in these patients would be associated with increased length of stay, hypotension, fluid requirements, and acute kidney injury (AKI). Materials and methods Thirty-two trauma patients in hemorrhagic shock on admission to the trauma bay (SBP <90 mm Hg × 2) were enrolled. Blood samples were obtained on ICU admission and 8, 16, 24, and 48 hours later. Plasma aldosterone (PA) and renin (PR) were assayed by radioimmunoassay. MD was defined as a ratio of PA/PR ≤2. Demographic data, injury severity score, ICU and hospital length of stay, fluid requirements, mean arterial pressure, serum sodium, hypotension, and risk for AKI were compared for patients with and without MD. Results At ICU admission, 48% of patients met criteria for MD. Patients with MD were significantly more likely to experience hypotension (MAP ≤60 mm Hg) during the study period. MD patients required significantly more units of blood in 48 h than non-MD patients (13 [7–22] versus 5 [2–7], P = 0.015) and had increased crystalloid requirements (18L [14–23] versus 9L [6–10], P < 0.001). MD patients were at higher risk for AKI according to RIFLE and AKIN criteria. Conclusions MD is a common entity in trauma patients presenting in hemorrhagic shock. Patients with MD required a more aggressive resuscitative effort, were more likely to experience hypotension, and had a higher risk of AKI than non-MD patients. Future studies are needed to fully understand the impact of MD following trauma and the potential role for hormonal replacement therapy. PMID:22683082

    Pathogenetic, diagnostic, and therapeutic problems and questions associated with ruptured cerebral aneurysms assume good knowledge of hemostatic processes. The three factors affecting hemostasia, namely, vasoactive, coagulative, and fibrinolytic risk factors in the blood, cerebro--spinal fluid, and at the site of damage to the vessel wall, are discussed withparticular reference to a thrombosing aneurysm. In the case of secondary hemorrhages it is necessary to determine the cause or pathogenesis, respectively, of the disturbance of coagulation or increase in fibrinolysis in order to be able to take suitable therapeutic measures and reduce the risk of secondary bleeding occurring within the first critical weeks after aneurysmal rupture.

    The clinical presentation of adrenal hemorrhage varies, depending on the extent of hemorrhage as well as the amount of adrenal cortex involved by the hemorrhage. We report here a case of neonatal adrenal hemorrhage revealed by late onset of neonatal jaundice. This adrenal hemorrhage most probably resulted from shoulder dystocia. The aim of this work was to focus on the fact that jaundice can be caused by adrenal hemorrhage and to emphasize the crucial importance of abdominal ultrasound in cases of persistent jaundice.

    Some 99,000 new cases of cancer of the colon are expected next year, an incidence rate higher than that for both cancer of the lung and cancer of the breast. Evidence from geographic pathology suggests that some environmental factors play a strong role in its etiology. Data obtained in the 1959 survey of one million people by the American Cancer Society and followed since, has failed to show correlation with any of the large number of factors listed. It is suggested that the etiology is one of multiple factors. The synergistic effect of exposure to asbestos and cigarette smoking in the production of bronchogenic carcinoma is demonstrated by data on cohorts of insulation workers. There was also a modest increase in the number of deaths from gastrointestinal cancer in asbestos workers, but smoking did not seem to act in synergistic fashion at that site, except perhaps in the esophagus. Deaths from cancer occurred almost entirely after a period of 20 years or more from initial exposure. The death rate from cancer tended to increase with duration of exposure, but a distinct rise over the expected was seen in those who had been exposed less than one year to amosite dust. PMID:4470947

    Gastrointestinal cancers represent a major public health problem worldwide. Immunotherapeutic strategies are currently under investigation in this setting and preliminary results of ongoing trials adopting checkpoint inhibitors are striking. Indeed, although a poor immunogenicity for GI has been reported, a strong biological rationale supports the development of immunotherapy in this field. The clinical and translational research on immunotherapy for the treatment of GI cancers started firstly with the identification of immune-related mechanisms possibly relevant to GI tumours and secondly with the development of immunotherapy-based agents in clinical trials. In the present review a general overview is firstly provided followed by a focus on major findings on gastric, colorectal, and hepatocellular carcinomas. Finally, pathological and molecular perspectives are provided since many efforts are ongoing in order to identify possible predictive biomarkers and to improve patients' selection. Many issues are still unsolved in this field; however, we strongly believe that immunotherapy might positively affect the natural history of a subgroup of GI cancer patients improving outcome and the overall quality of life.

    The excessive use of alcohol is a global problem causing many adverse pathological health effects and a significant financial health care burden. This review addresses the effect of alcohol consumption on the microbiota in the gastrointestinal tract (GIT). Although data are limited in humans, studies highlight the importance of changes in the intestinal microbiota in alcohol-related disorders. Alcohol-induced changes in the GIT microbiota composition and metabolic function may contribute to the well-established link between alcohol-induced oxidative stress, intestinal hyperpermeability to luminal bacterial products, and the subsequent development of alcoholic liver disease (ALD), as well as other diseases. In addition, clinical and preclinical data suggest that alcohol-related disorders are associated with quantitative and qualitative dysbiotic changes in the intestinal microbiota and may be associated with increased GIT inflammation, intestinal hyperpermeability resulting in endotoxemia, systemic inflammation, and tissue damage/organ pathologies including ALD. Thus, gut-directed interventions, such as probiotic and synbiotic modulation of the intestinal microbiota, should be considered and evaluated for prevention and treatment of alcohol-associated pathologies.

    The domestic chicken is a common model organism for human biological research and of course also forms the basis of a global protein industry. Recent methodological advances have spurred the recognition of microbiomes as complex communities with important influences on the health and disease status of the host. In this minireview, we provide an overview of the current state of knowledge of the chicken gastrointestinal microbiome focusing on spatial and temporal variability, the presence and importance of human pathogens, the influence of the microbiota on the immune system, and the importance of the microbiome for poultry nutrition. Review and meta-analysis of public data showed cecal communities dominated by Firmicutes and Bacteroides at the phylum level, while at finer levels of taxonomic resolution, a phylogenetically diverse assemblage of microorganisms appears to have similar metabolic functions that provide important benefits to the host as inferred from metagenomic data. This observation of functional redundancy may have important implications for management of the microbiome. We foresee advances in strategies to improve gut health in commercial operations through management of the intestinal microbiota as an alternative to in-feed subtherapeutic antibiotics, improvements in pre- and probiotics, improved management of polymicrobial poultry diseases, and better control of human pathogens via colonization reduction or competitive exclusion strategies. © 2014 Federation of European Microbiological Societies.

    The link between thromboembolism and cancer has been recognized for over 100 years. Venous thromboembolism (VTE) is associated with considerable morbidity in patients with cancer, with emerging research also indicating a detrimental effect on survival. Investigations aimed at improving outcomes for patients with cancer have focused on the role of low molecular weight heparin in primary and secondary prevention of VTE and in improving patient survival. Important fundamental questions remain unanswered, however, and a significant line of research needs to be dedicated to investigating VTE in GI cancers. The effect of VTE on survival needs to be clarified, as does the role of anticoagulation in this patient population. Opportunities for additional research include investigating methods to identify patients at risk of developing VTE and developing new strategies and therapeutic interventions to reduce the morbidity and mortality associated with VTE. This review focuses on the current understanding of VTE related to gastrointestinal cancers and directions of interest in research specific to GI cancers and VTE. PMID:19259275

    Sleep deprivation and impaired sleep quality have been associated with poor health outcomes. Many patients experience sleep disturbances, which can increase the risk of medical conditions such as hypertension, obesity, stroke, and heart disease as well as increase overall mortality. Recent studies have suggested that there is a strong association between sleep disturbances and gastrointestinal diseases. Proinflammatory cytokines, such as tumor necrosis factor, interleukin-1, and interleukin-6, have been associated with sleep dysfunction. Alterations in these cytokines have been seen in certain gastrointestinal diseases, such as gastroesophageal reflux disease, inflammatory bowel disease, liver disorders, and colorectal cancer. It is important for gastroenterologists to be aware of the relationship between sleep disorders and gastrointestinal illnesses to ensure good care for patients. This article reviews the current research on the interplay between sleep disorders, immune function, and gastrointestinal diseases.

    The most common and challenging gastrointestinal motility disorders in children include gastroesophageal reflux disease (GERD), esophageal achalasia, gastroparesis, chronic intestinal pseudo-obstruction, and constipation. GERD is the most common gastrointestinal motility disorder affecting children and is diagnosed clinically and treated primarily with acid secretion blockade. Esophageal achalasia, a less common disorder in the pediatric patient population, is characterized by dysphagia and treated with pneumatic balloon dilation and/or esophagomyotomy. Gastroparesis and chronic intestinal pseudo-obstruction are poorly characterized in children and are associated with significant morbidity. Constipation is among the most common complaints in children and is associated with significant morbidity as well as poor quality of life. Data on epidemiology and outcomes, clinical trials, and evaluation of new diagnostic techniques are needed to better diagnose and treat gastrointestinal motility disorders in children. We present a review of the conditions and challenges related to these common gastrointestinal motility disorders in children. PMID:24799835

    Hedgehog (Hh) signaling is critical for embryonic development and in differentiation, proliferation, and maintenance of multiple adult tissues. De-regulation of the Hh pathway is associated with birth defects and cancer. In the gastrointestinal tract, Hh ligands Sonic (Shh) and Indian (Ihh), as well as the receptor Patched (Ptch1), and transcription factors of Glioblastoma family (Gli) are all expressed during development. In the adult, Shh expression is restricted to the stomach and colon, while Ihh expression occurs throughout the luminal gastrointestinal tract, its expression being highest in the proximal duodenum. Several studies have demonstrated a requirement for Hh signaling during gastrointestinal tract development. However to date, the specific role of the Hh pathway in the adult stomach and intestine is not completely understood. The current review will place into context the implications of recent published data related to the biochemistry and cell biology of Hh signaling on the luminal gastrointestinal tract during development, normal physiology and subsequently carcinogenesis.

    Placenta previa is associated with maternal hemorrhage, but most literature focuses on morbidity in the setting of placenta accreta. We aim to characterize maternal morbidity associated with previa and to define risk factors for hemorrhage. This is a secondary cohort analysis of the NICHD Maternal-Fetal Medicine Units Network Cesarean Section Registry. This analysis included all women undergoing primary Cesarean delivery without placenta accreta. About 496 women with previa were compared with 24,201 women without previa. Primary outcome was composite maternal hemorrhagic morbidity. Non-hemorrhagic morbidities and risk factors for hemorrhage were also evaluated. Maternal hemorrhagic morbidity was more common in women with previa (19 versus 7%, aRR 2.6, 95% CI 1.9-3.5). Atony requiring uterotonics (aRR 3.1, 95% CI 2.0-4.9), red blood cell transfusion (aRR 3.8, 95% CI 2.5-5.7), and hysterectomy (aRR 5.1, 95% CI 1.5-17.3) were also more common with previa. For women with previa, factors associated with maternal hemorrhage were pre-delivery anemia, thrombocytopenia, diabetes, magnesium use, and general anesthesia. Placenta previa is an independent risk factor for maternal hemorrhagic morbidity. Some risk factors are modifiable, but many are intrinsic to the clinical scenario.

    Clinical deterioration in patients with spontaneous intracerebral hemorrhage has rarely been studied. It has been previously thought that intracranial hematomas bleed in a monophasic fashion. Recent studies have demonstrated continuous active bleeding within hours after the event, resulting in enlargement of the hematoma. However, acute sudden and fatal deterioration suggesting a rebleed is rarely reported. An 84-year-old man was admitted with a moderate-size hemorrhage in the putamen and was treated for hypertension during the first day of admission. He acutely demonstrated extensor posturing and light-fixed pupils. Repeat CT scan showed massive enlargement of the intracranial hematoma and extension into the ventricles causing acute hydrocephalus. A 72-year-old man was admitted with a mid-size hemorrhage in the putamen. Acute deterioration with loss of all brain stem reflexes except for cornea reflexes was associated with a large increase in volume of the hematoma, 7 hours after the initial hemorrhage. An 85-year-old woman was admitted with a small hemorrhage in the putamen and recovered to be able to walk unassisted. She suddenly died from a recurrent massive putaminal hemorrhage 2 weeks after the ictus. Patients with spontaneous intracerebral hemorrhage in the putamen may die acutely from fatal catastrophic enlargement of the initial hematoma hours to days after the ictus. In some patients with spontaneous intracerebral hemorrhage and clinical deterioration, rebleeding may be a possible mechanism.

    2008-04-01

    Argentine hemorrhagic fever (AHF) is a rodent-borne illness caused by the arenavirus Junin that is endemic to the humid pampas of Argentina. AHF has had significant morbidity since its emergence in the 1950s, with a case-fatality rate of the illness without treatment between 15% and 30%. The use of a live attenuated vaccine has markedly reduced the incidence of AHF. Present specific therapy involves the transfusion of immune plasma in defined doses of neutralizing antibodies during the prodromal phase of illness. However, alternative forms of treatment are called for due to current difficulties in early detection of AHF, related to its decrease in incidence, troubles in maintaining adequate stocks of immune plasma, and the absence of effective therapies for severely ill patients that progress to a neurologic-hemorrhagic phase. Ribavirin might be a substitute for immune plasma, provided that the supply is guaranteed. Immune immunoglobulin or monoclonal antibodies should also be considered. New therapeutic options such as those being developed for systemic inflammatory syndromes should also be valuated in severe forms of AHF.

    Invasive mucormycosis is a rare fungal infection in immunocompromised hosts, but it carries a high mortality rate. Primary gastrointestinal disease is the least frequent form of presentation. Early diagnosis and treatment are critical in the management; however, symptoms are typically non-specific in gastrointestinal disease, leading to delayed therapy. To describe the clinical presentation, diagnosis, treatment and outcomes of gastrointestinal mucormycosis in immunocompromised hosts, we reviewed all cases of primary gastrointestinal mucormycosis in immunocompromised hosts reported in English literature as well as in our Institution from January 1st 1991 to December 31st 2013 for a total of 31 patients. About 52% of patients underwent solid organ transplant (SOT), while the rest had an underlying haematologic malignancy. Abdominal pain was the most common presenting symptom, followed by gastrointestinal bleeding and fever. Gastric disease was more common in SOT, whereas those with haematologic malignancy presented with intestinal disease (P = 0.002). Although gastrointestinal mucormycosis remains an uncommon condition in immunocompromised hosts, it carries significant morbidity and mortality, particularly in cases with intestinal involvement. A high index of suspicion is of utmost importance to institute early and appropriate therapy and improve outcomes.

  1. Lipomas of the gastrointestinal system.

    2012-01-01

    Lipomas are rare benign tumors in the gastrointestinal system. Within the gastrointestinal system, 65% of the lipomas are located in the colon (sigmoid part of the colon or rectum) and rarely in the stomach and esophagus. The paper presents two gastrointestinal lipomas. First is the case of lipoma of the sigmoid colon and the other one is gastric lipoma. In both cases the material was sent for histopathological analysis due to suspicion of malignancy of the lesions. In both cases, the histopathologic analysis showed tumor made of mature adipocytes, localized in the submucosa both of the stomach and intestine. Hypercellularity and/or atypia of the cell was found in neither case. Lipomas are shown because of its atypical localization and clinically suspicious malignancy in the stomach and sigmoid colon. These cases show that the applied methods of preoperative diagnosis of tumors in the gastrointestinal system are not sufficient to determine the origin and biological behavior of tumors. Histopathological diagnosis provides a correct insight into the nature of tumors and determine the course of treatment. This paper presents a rare localization of lipomas in the gastrointestinal system. The preoperative diagnosis of lesions in the gastrointestinal system may not be sufficient to determine the origin and biological behavior of the lesions, hence the histopathological diagnosis gives an accurate insight into the nature of the change, preventing the possibility of further aggressive therapy.

    2011-03-01

    The determination of the cause and manner of death for a body recovered from the water can be difficult because of a lack of autopsy findings specific for drowning. This case report describes a 30-year-old man found submerged at the bottom of a hotel pool. An autopsy revealed scleral hemorrhages and fascial hemorrhages of multiple muscles of the anterior and posterior neck bilaterally. No evidence of traumatic injury was on the surface of the body. An investigation by law enforcement found no evidence of foul play. The occurrence of petechial and neck hemorrhage in a body recovered from the water is controversial, and a review of this literature will be given. We suggest that fascial hemorrhages of the muscles of the neck, as well as cephalic hemorrhages, can be explained by drowning-related elevated central venous pressure that is communicated to the head through the valveless veins of the neck.

    The incidence of upper gastrointestinal (GI) bleeding in mechanically ventilated ICU patients receiving enteral alimentation was reviewed and compared to bleeding occurring in ventilated patients receiving prophylactic antacids or cimetidine. Of 250 patients admitted to our ICU during a 1-yr time period, 43 ventilated patients were studied. Patients in each group were comparable with respect to age, respiratory diagnosis, number of GI hemorrhage risk factors, and number of ventilator, ICU, and hospital days. Twenty-one patients had evidence of GI bleeding. Fourteen of 20 patients receiving antacids and 7 of 9 patients receiving cimetidine had evidence of GI bleeding. No bleeding occurred in 14 patients receiving enteral alimentation. Complications of enteral alimentation were few and none required discontinuation of enteral alimentation. Our preliminary data suggest the role of enteral alimentation in critically ill patients may include not only protection against malnutrition but also protection against GI bleeding.

    This is the first attempt at defining criteria for functional gastrointestinal disorders (FGIDs) in infancy, childhood, and adolescence. The decision-making process was as for adults and consisted of arriving at consensus, based on clinical experience. This paper is intended to be a quick reference. The classification system selected differs from the one used in the adult population in that it is organized according to main complaints instead of being organ-targeted. Because the child is still developing, some disorders such as toddler's diarrhea (or functional diarrhea) are linked to certain physiologic stages; others may result from behavioral responses to sphincter function acquisition such as fecal retention; others will only be recognizable after the child is cognitively mature enough to report the symptoms (e.g., dyspepsia). Infant regurgitation, rumination, and cyclic vomiting constitute the vomiting disorders. Abdominal pain disorders are classified as: functional dyspepsia, irritable bowel syndrome (IBS), functional abdominal pain, abdominal migraine, and aerophagia. Disorders of defecation include: infant dyschezia, functional constipation, functional fecal retention, and functional non-retentive fecal soiling. Some disorders, such as IBS and dyspepsia and functional abdominal pain, are exact replications of the adult criteria because there are enough data to confirm that they represent specific and similar disorders in pediatrics. Other disorders not included in the pediatric classification, such as functional biliary disorders, do occur in children; however, existing data are insufficient to warrant including them at the present time. For these disorders, it is suggested that, for the time being, clinicians refer to the criteria established for the adult population.

However, in certain parts of the intestine, such as the rectum and gastroesophagus, the sensation of pain can be preceded by a non-painful sensation of distension at low levels of stimulation. GI pain is often dull, poorly defined and difficult to pinpoint. In some cases, GI pain is projected to areas of the body distant from the source organ ("referred" pain). These characteristics indicate that the representation of internal organs within the nervous system is very imprecise. Experimental evidence based on behavioral, neurological and clinical testing shows that most GI pain is the result of activity in afferent visceral sensory fibers contained in sympathetic nerves, and that the afferent intestinal innervation by means of parasympathetic nerves is not essentially related to GI pain signalling and transmission. As for the peripheral sensory receptor coding mechanism in the intestine, experimental tests have shown the existence of specific visceral nociceptors in certain places (e.g., the biliary system) and the existence of a king of non-specific "intensity" receptors in others (e.g. the colon). In any case, the number of afferent nociceptive fibers in the intestine is minimal, and this accounts for the fact that large areas of the GI tract appear to be insensitive or to require considerable stimulation before pain can be elicited. The few afferent nociceptive fibers contained in the sympathetic nerves can excite quite a few second order neurons in the medulla spinalis, which in turn generate an extensive divergence within the medulla spinalis and brain stem, including at times long supraspinal branches. This divergent input can activate different motor, autonomous and sensory systems, thus triggering the general reactions which characterize visceral nociception: diffuse pain which is difficult to pinpoint

    Evidence for positive health benefits of Lactobacilli applies to only a few strains used for commercial applications. It is generally agreed that a probiotic must be capable of colonizing the intestinal tract to influence human health; this requirement disqualifies many of the strains currently used in fermented dairy products. Lactobacillus GG, a variant of L. casei sps rhamnosus, has been studied extensively in adults and children. When consumed as a dairy product or as a lyophilized powder, LGG colonizes the gastrointestinal tract for 1-3 days in most individuals and up to 7 days in about 30% of subjects. Traveler's diarrhea, antibiotic-associated diarrhea, and relapsing Clostridium difficile colitis are improved with LGG. In infantile diarrhea, the severity and duration of the attack is reduced. LGG-fermented milk lessens the intestinal permeability defects caused by exposure to cows milk or rotavirus infection. LGG has proven beneficial effects on intestinal immunity. It increases the numbers of IgA and other immunoglobulin-secreting cells in the intestinal mucosa. LGG stimulates local release of interferon. It facilitates antigen transport to underlying lymphoid cells, which serves to increase antigen uptake in Peyer's patches. LGG also acts as an immunoadjuvant for oral vaccines. In an animal model of colon cancer, LGG reduced the incidence of chemically induced tumors in the large bowel of rodents. Extensive safety testing has shown no pathogenic potential in humans or animals. Probiotic cultures of Lactobacilli have the potential to bring substantial health benefits to the consumer. The purported benefits for any probiotic must pass the highest standards of scientific scrutiny before the claims can be accepted.

    Background: Extranodal lymphoma may arise anywhere outside lymph nodes mostly in the gastrointestinal (GI) tract as non-Hodgkin's disease. We reviewed the clinicopathological features and treatment results of patients with primary GI lymphoma. Materials and Methods: A total number of 30 cases with primary GI lymphoma were included in this study. Patients referred to the Radiation Oncology Department of Omid Hospital (Mashhad, Iran) during a 5-year period (2006-11). Clinical, paraclinical, and radiological data was collected from medical records of the patients. Results: Out of the 30 patients with primary GI lymphoma in the study, 12 were female (40%) and 18 were male (60%) (male to female ratio: 3/2). B symptoms were present in 27 patients (90%). Antidiuretic hormone (LDH) levels were elevated in 9 patients (32.1%). The most common primary site was stomach in 14 cases (46.7%). Other common sites included small intestine and colon each in 8 patients (26.7%). All patients had histopathologically proven non-Hodgkin's lymphoma. The most common histologic subtype was diffuse large B-cell lymphoma (DLBL) in 16 patients (53.3%). In addition, 28 patients (93.3%) received chemotherapy with cyclophosphamide, vincristine, doxorubicin, prednisolone (CHOP regimen). The median course of chemotherapy was 6 cources. Moreover, 8 patients (26.7%) received radiotherapy with cobalt 60. The median follow-up time was 26 months. The overall 5-year survival rate was 53% and the median survival time was 60 months. Conclusion: Primary GI lymphoma is commonly seen in stomach and small intestine and mostly is DLBCL or mucosa-associated lymphoid tissue (MALT) lymphoma. PMID:23626617

    The gastrointestinal (GI) system is responsible for the digestion and absorption of ingested food and liquids. Due to the complexity of the GI tract and the substantial volume of material that could be covered under the scope of GI physiology, this chapter briefly reviews the overall function of the GI tract, and discusses the major factors affecting GI physiology and function, including the intestinal microbiota, chronic stress, inflammation, and aging with a focus on the neural regulation of the GI tract and an emphasis on basic brain-gut interactions that serve to modulate the GI tract. GI diseases refer to diseases of the esophagus, stomach, small intestine, colon, and rectum. The major symptoms of common GI disorders include recurrent abdominal pain and bloating, heartburn, indigestion/dyspepsia, nausea and vomiting, diarrhea, and constipation. GI disorders rank among the most prevalent disorders, with the most common including esophageal and swallowing disorders, gastric and peptic ulcer disease, gastroparesis or delayed gastric emptying, irritable bowel syndrome (IBS), and inflammatory bowel disease (IBD). Many GI disorders are difficult to diagnose and their symptoms are not effectively managed. Thus, basic research is required to drive the development of novel therapeutics which are urgently needed. One approach is to enhance our understanding of gut physiology and pathophysiology especially as it relates to gut-brain communications since they have clinical relevance to a number of GI complaints and represent a therapeutic target for the treatment of conditions including inflammatory diseases of the GI tract such as IBD and functional gut disorders such as IBS.

    Systematic revue of different conservative and non-conservative surgical treatment of postpartum hemorrhage (PPH). Elaboration of surgical strategy after failed medical treatment of PPH. French and English publications were identified through PubMed and Cochrane databases. Each obstetrical unit has to rewrite a full protocol of management of PPH depending on local environment quickly available in theatre (professional consensus). Conservative surgical treatment of PPH: efficacy of vascular ligature (bilateral uterine artery ligation (BUAL) or bilateral hypogastric artery ligation (BHAL)) as a first line of surgical treatment of PPH is about 60 % to 70 % (EL4). Bilateral uterine artery ligation (BUAL) is easy to perform with low rate of immediate severe complication (professional consensus). BUAL as BHAL seems not to affected fertility and obstetrical outcomes of next pregnancies (EL4). Efficacy of haemostatics brace suturing in case of failed medical treatment of PPH is about 75 % (EL3), without risk of major obstetrical complications at the next pregnancy (EL4). Radical surgical treatment of PPH: total hysterectomy is not significantly associated with more urinary tract injury in comparison with subtotal hysterectomy (EL3). Choice of surgical procedure of hysterectomy (total or subtotal) will depend on local consideration and clinicians habits (professional consensus). Surgical strategy: conservative surgical treatment are efficient and associated with low morbidity, they have to be primarily performed in women with further fertility desire. Specific medical consideration as massive PPH or cardiovascular instability has to consider performing haemostatic hysterectomy as the first line surgical treatment of PPH. PPH during caesarean delivery: in case of PPH during caesarean section, embolisation is not recommended, surgical treatment using vascular devascularisation or compression brace suturing should be performed (professional consensus).

    Dieulafoy reported three cases of massive gastric hemorrhage due to a dilated submucosal artery in 1898, and since then, more than 100 cases of this gastric vascular malformation have been reported in the literature. These same pathologic lesions are even a rarer occurrence in the small bowel. This article reports a 38-year-old hypotensive male who presented to the hospital after an acute onset of massive lower gastrointestinal hemorrhage; superior mesenteric angiography demonstrated an actively bleeding lesion in a proximal jejunal branch. Intraoperative small bowel endoscopy via an enterotomy demonstrated a 4 mm bleeding submucosal lesion 30 cm distal to the ligament of Treitz. A literature review revealed six other cases of Dieulafoy's vascular malformation that occurred in the small bowel, with the lesions located in the proximal jejunum between 15 cm and 45 cm distal to the ligament of Treitz. The cause of these lesions is unknown. This case demonstrates the importance of preoperative angiography and intraoperative endoscopy when massive lower gastrointestinal hemorrhage is suspected to be from a small bowel source.

    To describe the natural history of intraocular hemorrhages related to subarachnoid hemorrhage (SAH) as a result of ruptured intracranial aneurysms. Retrospective review of patients with cerebral aneurysms examined by a referral neuro-ophthalmology service between 1980 and 1998. Patients with intraocular hemorrhages associated with SAH as a result of ruptured aneurysms were followed up without vitrectomy, unless bilateral vitreous hemorrhage occurred. Seventy of 450 patients with cerebral aneurysms had an SAH. Of these, 30 eyes of 19 patients had intraocular hemorrhages. Fourteen eyes had a vitreous hemorrhage; 12 had subhyaloid blood without a vitreous hemorrhage; and four had retinal hemorrhages alone. Two patients died shortly after presentation. Twenty-eight eyes were followed up for a mean of 4.8 years. Initial visual acuity was 20/100 to light perception in eyes with a vitreous hemorrhage, 20/20 to 20/400 in eyes with subhyaloid blood, and 20/20 to 20/40 in eyes with retinal hemorrhages. Three of the 12 eyes with a vitreous hemorrhage underwent vitrectomy. Of the nonoperated eyes, final visual acuity was at least 20/30 in 19 (76%) eyes, 20/40 to 20/60 in four (16%) eyes, and 20/100 in both eyes of one patient with premacular subhyaloid blood. None of the nonoperated eyes developed cataract formation or progression, retinal tears, or retinal detachment. Epiretinal membrane developed in one eye and pigmentary maculopathy developed in five. Except for patients with bilateral vitreous hemorrhages, early vitrectomy may not be necessary in most cases of intraocular hemorrhages associated with nontraumatic SAH.

    Klippel-Trenaunay syndrome is a congenital vascular anomaly characterized by a triad of varicose veins, cutaneous capillary malformation, and hypertrophy of bone and (or) soft tissue. Gastrointestinal vascular malformations in Klippel-Trenaunay syndrome may present with gastrointestinal bleeding. The majority of patients with splenic hemangiomatosis and/or left inferior vena cava are asymptomatic. We herein report a case admitted to the gastroenterology clinic with life-threatening hematochezia and symptomatic iron deficiency anemia. Due to the asymptomatic mild intermittent hematochezia, splenic hemangiomas and left inferior vena cava, the patient did not seek any help for gastrointestinal bleeding until his admittance to our department for evaluation of massive gastrointestinal bleeding. He was referred to angiography because of his serious pathogenetic condition and inefficiency of medical therapy. The method showed that hemostasis was successfully achieved in the hemorrhage site by embolism of corresponding vessels. Further endoscopy revealed vascular malformations starting from the stomach to the descending colon. On the other hand, computed tomography revealed splenic hemangiomas and left inferior vena cava. To the best of our knowledge, this is the first Klippel-Trenaunay syndrome case presenting with gastrointestinal bleeding, splenic hemangiomas and left inferior vena cava. The literature on the evaluation and management of this case is reviewed.

    This pictorial review is based on our experience of the follow-up of 120 patients at our multidisciplinary center for hereditary hemorrhagic telangiectasia (HHT). Rendu-Osler-Weber disease or HHT is a multiorgan autosomal dominant disorder with high penetrance, characterized by epistaxis, mucocutaneous telangiectasis, and visceral arteriovenous malformations (AVMs). The research on gene mutations is fundamental and family screening by clinical examination, chest X-ray, research of pulmonary shunting, and abdominal color Doppler sonography is absolutely necessary. The angioarchitecture of pulmonary AVMs can be studied by unenhanced multidetector computed tomography; however, all other explorations of liver, digestive bowels, or brain require administration of contrast media. Magnetic resonance angiography is helpful for central nervous system screening, in particular for the spinal cord, but also for pulmonary, hepatic, and pelvic AVMs. Knowledge of the multiorgan involvement of HHT, mechanism of complications, and radiologic findings is fundamental for the correct management of these patients.

    Introduction Paroxysmal sympathetic hyperactivity (PSH) is a hyperadrenergic syndrome that may follow acute brain injury characterized by episodic, hyperadrenergic alterations in vital signs. Identifying commonality in lesion localization in patients with PSH is challenging, but intraparenchymal hemorrhage (IPH) represents a focal injury that might provide insight. We describe a series of patients with IPH that developed PSH, and review the literature. Methods Patients with IPH who developed PSH were identified from OHSU hospital records. A literature review was conducted to identify similar cases through PUBMED, OVID, and Google Scholar. Results Three cases meeting criteria for PSH were identified. Hemorrhage volume ranged from 70 to 128 mL, and intracranial hemorrhage score ranged from 2 to 3. The laterality of the hemorrhage and significant volume of hemorrhage was similar in each of the patients, specifically all hemorrhages were large, subcortical, and right-sided. A literature search identified six additional cases, half of whom reported a right hemisphere hemorrhage and the majority also had subcortical localization. Conclusions Our literature review identified six cases of IPH associated with PSH with five cases having subcortical lesion locations, echoing the areas of disruption in our three cases. On the basis of these observations, we hypothesize that injuries along the pathway from the insular cortex to downstream sympathetic centers may remove tonic inhibition leading to unchecked sympathetic outflow. Prospective investigations of lesion location in patients with IPH and PSH are warranted to test this hypothesis, especially with advanced neuroimaging techniques. PMID:24904923

    Developmental venous anomalies (DVA) and cavernous malformations (CM) are a common form of mixed vascular malformation. The relationship between DVA, CM and hemorrhage is complicated. It is important to differentiate hemorrhagic CM and hemorrhagic DVA. A retrospective review of all patients with acute spontaneous intracerebral hemorrhages (ICH) between 1 May 2008 and 1 May 2013 was performed. ICH due to DVA or CM were identified and compared for demographic features, clinical symptoms, neurological deficits, and radiological findings. A total of 1706 patients with acute spontaneous ICH were admitted to our hospital during the study period. Among these, 10 (0.59%) were caused by DVA and 42 (2.47%) were caused by CM. No significant differences were found in age (p=0.252) or sex ratio (p=1.000) between the two groups. Compared with CM-induced ICH, DVA-induced ICH were characterized by cerebellar predominance (p=0.000) and less severe neurological deficits (p=0.008). Infratentorial hemorrhagic DVA are characterized by cerebellar predominance and benign clinical course. Infratentorial hemorrhagic CM are mainly located in the brainstem. DVA should be given suspected rather than CM when considering the etiology of a cerebellar hemorrhage, especially in young adults. Copyright © 2015 Elsevier Ltd. All rights reserved.

    The purpose of this study is to estimate the cumulative incidence, patient characteristics, and potential risk factors for secondary hemorrhage after total laparoscopic hysterectomy. All women who underwent total laparoscopic hysterectomy at Paul's Hospital between January 2004 and April 2012 were included in the study. Patients who had bleeding per vaginam between 24 hours and 6 weeks after primary surgery were included in the analysis. A total of 1613 patients underwent total laparoscopic hysterectomy during the study period, and 21 patients had secondary hemorrhage after hysterectomy. The overall cumulative incidence of secondary hemorrhage after total laparoscopic hysterectomy was 1.3%. The mean size of the uterus was 541.4 g in the secondary hemorrhage group and 318.9 g in patients without hemorrhage, which was statistically significant. The median time interval between hysterectomy and secondary hemorrhage was 13 days. Packing was sufficient to control the bleeding in 13 patients, and 6 patients required vault suturing. Laparoscopic coagulation of the uterine artery was performed in 1 patient. Uterine artery embolization was performed twice in 1 patient to control the bleeding. Our data suggest that secondary hemorrhage is rare but may occur more often after total laparoscopic hysterectomy than after other hysterectomy approaches. Whether it is related to the application of thermal energy to tissues, which causes more tissue necrosis and devascularization than sharp culdotomy in abdominal and vaginal hysterectomies, is not clear. A large uterus size, excessive use of an energy source for the uterine artery, and culdotomy may play a role.

    Post-tonsillectomy hemorrhage (PTH) seems to be a rare but unavoidable complication. Due to the frequency of performed tonsillectomies, it can be estimated that a certain amount may result in a lethal outcome. This study was undertaken to evaluate the clinical features of these rare cases. Retrospective case series of five patients with lethal post-tonsillectomy hemorrhage are reported after they had undergone tonsillectomy by four different surgeons. The relevant literature was reviewed. The youngest patient was 42 months and the oldest almost 13 years old. All patients were male. Three patients had left the hospital against surgeon's recommendation 5 days following tonsillectomy. Preceding episodes of bleeding prior to the lethal bleeding occurred in two patients. Lethal PTH occurred in four patients within 5-9 days, the latest bleeding 39 days after surgery. In the literature, lethal PTH was described for eight patients since 1958. The youngest patient was 4 years, the oldest 18 years old (mean: 8.6 years; median: 6.5 years). In three patients, lethal PTH occurred on the day of surgery and the latest bleeding 54 days after surgery. Due to the paucity of reports, little reliable information can be obtained from the literature. It remains unclear, whether or not this reflects the true incidence of this complication. The experience with the five reported cases suggests, that immediate surgical treatment may have avoided lethal outcome in most cases. Therefore, a close postoperative follow-up is advisable to detect any episode of bleeding as soon as possible which should be referred to a specialist. Certainly, the collected data do not suffice to establish general guidelines, indicating that further collection of cases is required to assess characteristics of lethal PTH.

    Abstract Primary gastrointestinal lymphoma (PGIL) is a rare malignant tumor without standard diagnosis and treatment methods. This study is aimed to systematically analyze its clinical characteristics and draw out an appropriate flow chart of diagnosis and treatment process for PGIL in China. This study retrospectively analyzed the clinicopathological characteristics, diagnostic approaches, prognostic factors, and therapeutic modalities in 415 cases of PGIL in Chinese province of Guangdong. A systematic review was conducted in 118 studies containing 5075 patients to further identify clinical manifestations and mortalities of therapeutic modalities. The most common clinical presentations were abdominal pain and bloody stools. Endoscopic biopsy was an important diagnostic means, and usually more than once to make a definite diagnosis. Retrospective multicenter clinical study showed that younger onset age (<60 years), female, one region involved, one lesion, early stage, International Prognostic Index (IPI ≤1), normal lactate dehydrogenase (LDH), normal albumin, and nonemergency operation were significant prognostic factors for B-cell lymphoma; non-B symptom, tumor restricted to gastric or ileocecal region, one lesion, performance status (PS ≤1), normal LDH, and nonsurgery alone were significant prognostic factors for T-cell lymphoma. Site of origin and IPI were independent prognostic factors for B-cell lymphoma; PS was the independent prognostic factor for T-cell lymphoma. And T-cell lymphoma had worse overall survival (OS) and progression-free survival (PFS) than B-cell lymphoma. Among different therapeutic modalities, chemotherapy alone or combined with surgery showed better OS and PFS than surgery alone for diffuse large B-cell lymphoma (DLBCL) of stage I/II E and T-cell lymphoma. For DLBCL of stage III E/IV and mucosa-associated lymphoid tissue lymphoma, OS and PFS did not differ among different therapeutic groups. In meta-analysis, surgery plus chemotherapy

    To elucidate the characteristics of hemorrhagic gastric/duodenal ulcers in a post-earthquake period within one medical district. Hemorrhagic gastric/duodenal ulcers in the Iwate Prefectural Kamaishi Hospital during the 6-mo period after the Great East Japan Earthquake Disaster were reviewed retrospectively. The subjects were 27 patients who visited our hospital with a chief complaint of hematemesis or hemorrhagic stool and were diagnosed as having hemorrhagic gastric/duodenal ulcers by upper gastrointestinal endoscopy during a 6-mo period starting on March 11, 2011. This period was divided into two phases: the acute stress phase, comprising the first month after the earthquake disaster, and the chronic stress phase, from the second through the sixth month. The following items were analyzed according to these phases: age, sex, sites and number of ulcers, peptic ulcer history, status of Helicobacter pylori (H. pylori) infection, intake of non-steroidal anti-inflammatory drugs, and degree of impact of the earthquake disaster. In the acute stress phase from 10 d to 1 mo after the disaster, the number of patients increased rapidly, with a nearly equal male-to-female ratio, and the rate of multiple ulcers was significantly higher than in the previous year (88.9% vs 25%, P < 0.005). In the chronic stress phase starting 1 mo after the earthquake disaster, the number of patients decreased to a level similar to that of the previous year. There were more male patients during this period, and many patients tended to have a solitary ulcer. All patients with duodenal ulcers found in the acute stress phase were negative for serum H. pylori antibodies, and this was significantly different from the previous year's positive rate of 75% (P < 0.05). Severe stress caused by an earthquake disaster may have affected the characteristics of hemorrhagic gastric/duodenal ulcers.

    Wabitsch, Martin

    2017-01-01

    The long-lasting weight-reducing effect of bariatric surgical procedures cannot simply be explained by the malabsorption of nutrients and the subsequent energy deficit due to this malabsorption. Clinical studies have shown that the reorganization of the anatomy of the gut and the subsequent alterations of gastrointestinal physiology have a large impact on the secretion and function of gastrointestinal hormones, which regulate hunger and satiety. These changes have been named the BRAVE effect: bile flow alteration, reduction of gastric size, anatomical gut rearrangement and altered flow of nutrients, vagal manipulation, and enteric gut modulation. In addition, the metabolic improvements, for example, increased insulin secretion and improved glucose sensitivity after bariatric surgery cannot simply be explained by the weight loss achieved by the operation. Several metabolic improvements occur directly after bariatric surgery even before significant weight loss has occurred. Clinical studies revealed that the altered gastrointestinal physiology and the postoperative profile of gastrointestinal hormones are responsible for these metabolic alterations. Further insights into the changes of gastrointestinal hormone profiles before and after bariatric surgery may open new ways to prevent the surgical procedure and probably obtain equivalent results by nutraceuticals. © 2017 S.

    Acute kidney injury occurs in 33-50% of patients with rhabdomyolysis and infections remain one of the major contributing factors. The incidence of rhabdomyolysis in non-hemorrhagic dengue virus infection is quite low and may go unnoticed, especially if the presentation is not florid. We report a case of a young male patient, sero-positive for dengue, with no hemorrhagic manifestations or hypotension, who developed rhabdomyolysis complicated by renal failure. The patient eventually needed dialysis support and later recovered fully. Clinicians need to be aware of the occurrence of rhabdomyolysis even in patients without the hemorrhagic manifestations of dengue viral infection and should employ early preventive strategies in such cases.

    Argentine hemorrhagic fever is a systemic viral disease caused by Junin virus, with a mortality of 15-30% in untreated individuals. Current specific therapy is highly effective in reducing mortality, and consists of the early administration of immune plasma in defined doses of specific neutralizing antibodies per kg of body weight. However, several reasons suggest the need to investigate alternative therapies. Ribavirin, a broad spectrum antiviral agent, is effective in the treatment of other viral hemorrhagic fevers, and the studies done with Junin virus infections to date indicate that this drug may also have a beneficial effect in Argentine hemorrhagic fever.

    There are few data on platelet function in intracerebral hemorrhage (ICH). We prospectively enrolled 69 patients with ICH and measured platelet function on admission. Aspirin use before ICH was associated with reduced platelet activity. Less platelet activity was associated with intraventricular hemorrhage (516.5 [interquartile range (IQR), 454-629.25] vs 637 [IQR, 493-654] aspirin reaction units; p = 0.04) and death at 14 days (480.5 [IQR, 444.5-632.5] vs 626 [IQR, 494-652] aspirin reaction units; p = 0.04). Objective measures of platelet function on admission are associated with intraventricular hemorrhage and death after ICH.

    Two patients with Meckel's Cave meningiomas were initially hospitalized as a result of subarachnoid hemorrhage. Four-vessel angiography was necessary to exclude other causes of bleeding while demonstrating these lesions. Apoplectic presentation in both cases led to early diagnosis and successful surgical therapy. A review of the literature reveals subarachnoid hemorrhage to be a rarity in association with meningiomas. The two patients currently reported are believed to be the only examples on record of hemorrhagic meningiomas arising from the region of Meckel's Cave.

The urge to defecate, both during and immediately after running, occurred in over a third of runners. Bowel movements (35%) and diarrhea (19%) were relatively common after running, and runners occasionally interrupted hard runs or races for bowel movements (18%) or diarrhea (10%). Lower gastrointestinal disturbances were more frequent in women than in men and in younger than in older runners. Awareness of the frequency and nature of gastrointestinal symptoms documented by this survey will assist physicians in evaluating abdominal complaints in runners. PMID:6506684

    A gastrointestinal fistula is a common occurrence, especially after surgery. Patients who develop a fistula may have an infection, surgically altered anatomy, nutritional deficiency, or organ failure, making surgical revision more difficult. With advancements in flexible endoscopic devices and technology, new endoscopic options are available for the management of gastrointestinal fistulae. Endoscopically deployable stents, endoscopic suturing devices, through-the-scope and over-the-scope clips, sealants, and fistula plugs can be used to treat fistulae. These therapies are even more effective in combination. Despite the inherent challenges in patients with fistulae, endoscopic therapies for treatment of fistulae have demonstrated safety and efficacy, allowing many patients to avoid surgical fistula repair. In this paper, we review the emerging role of endoscopy in the management of gastrointestinal fistulae. PMID:28845140

    Gastrointestinal endoscopy has become an important modality for the diagnosis and treatment of various gastrointestinal disorders. One of its major advantages is that it is minimally invasive and has an excellent safety record. Nevertheless, some complications do occur, and endoscopists are well aware and prepared to deal with the commonly recognized ones including bleeding, perforation, infection, and adverse effects from the sedative medications. Air embolism is a very rare endoscopic complication but possesses the potential to be severe and fatal. It can present with cardiopulmonary instability and neurologic symptoms. The diagnosis may be difficult because of its clinical presentation, which can overlap with sedation-related cardiopulmonary problems or neurologic symptoms possibly attributed to an ischemic or hemorrhagic central nervous system event. Increased awareness is essential for prompt recognition of the air embolism, which can allow potentially life-saving therapy to be provided. Therefore, we wanted to review the risk factors, the clinical presentation, and the therapy of an air embolism from the perspective of the practicing endoscopist.

    Upper gastrointestinal bleeding (UGIB) is a potentially life threatening medical emergency requiring an appropriate diagnostic and therapeutic approach. Therefore, the primary focus in a child with UGIB is resuscitation and stabilization followed by a diagnostic evaluation. The differential diagnosis of UGIB in children is determined by age and severity of bleed. In infants and toddlers mucosal bleed (gastritis and stress ulcers) is a common cause. In children above 2 y variceal bleeding due to Extra-Hepatic Portal Venous Obstruction (EHPVO) is the commonest cause of significant UGIB in developing countries as against peptic ulcer in the developed countries. Upper gastrointestinal endoscopy is the most accurate and useful diagnostic tool to evaluate UGIB in children. Parenteral vitamin K (infants, 1-2 mg/dose; children, 5-10 mg) and parenteral Proton Pump Inhibitors (PPI's), should be administered empirically in case of a major UGIB. Octreotide infusion is useful in control of significant UGIB due to variceal hemorrhage. A temporarily placed, Sengstaken-Blakemore tube can be life saving if pharmacologic/ endoscopic methods fail to control variceal bleeding. Therapy in patients having mucosal bleed is directed at neutralization and/or prevention of gastric acid release; High dose Proton Pump Inhibitors (PPIs, Pantoprazole) are more efficacious than H2 receptor antagonists for this purpose.

    Mycosis fungoides (MF) is an uncommon T-cell lymphoma which characteristically involves the skin. Two patients with MF are described who developed fatal complications secondary to involvement of the gastrointestinal tract. One developed malabsorption due to small intestinal involvement; the other had a massive haemorrhage from an ulcerated nodule of tumour in the stomach. The potential for extracutaneous spread is discussed, and it is emphasized that bowel infiltration should be considered in any patient with MF who develops gastrointestinal symptoms or complications.

    As the number of diagnostic and therapeutic gastrointestinal endoscopies is increasing, and there is an increase in number of patients taking blood thinners, we are seeing more and more patients on blood thinners prior to endoscopic procedures. Gastrointestinal bleeding or thromboembolism can occur in this category of patients in the periendoscopic period. To better manage these patients, endoscopists should have a clear concept about the various blood thinners in the market. Patients’ risk of thromboembolism off anticoagulation, and the risk of bleeding from endoscopic procedures should be assessed prior to endoscopy. The endoscopic procedure should be done when it is safe to do it. PMID:27668068

    The gastrointestinal stromal tumours (GIST) are the most common soft tissue sarcomas of the digestive tract. They are usually found in the stomach (60-70%) and small intestine (25-30%) and, less commonly, in the oesophagus, mesentery, colon, or rectum. The symptoms present at diagnosis are, gastrointestinal bleeding, abdominal pain, abdominal mass, or intestinal obstruction. The type of symptomatology will depend on the location and size of the tumour. The definitive diagnosis is histopathological, with 95% of the tumours being positive for CD117. This is an observational and descriptive study of 5cases of small intestinal GIST that presented with gastrointestinal bleeding as the main symptom. The period from the initial symptom to the diagnosis varied from 1 to 84 months. The endoscopy was inconclusive in all of the patients, and the diagnosis was made using computed tomography and angiography. Treatment included resection in all patients. The histopathological results are also described. GIST can have multiple clinical pictures and unusual symptoms, such as obscure gastrointestinal bleeding. The use of computed tomography and angiography has shown to be an important tool in the diagnosis with patients with small intestine GISTs. Copyright © 2016. Publicado por Masson Doyma México S.A.

    Cryptic intracerebral hemorrhage as an etiological factor in fetal hydrocephalus has been postulated but not described at autopsy. Four fetuses with overt hydrocephalus diagnosed by in utero ultrasound examination were examined at autopsy at 19-22 weeks gestation. Although a hemorrhagic etiology was not evident on ultrasound, hemosiderin-containing macrophages and associated reactive changes were found to obstruct the otherwise well-formed cerebral aqueduct in all four. Coagulopathy due to thrombocytopenia was implicated in one case. Anomalies involving other parts of the body were identified in two cases, although a direct link to the hydrocephalus was not obvious. The abnormality was isolated in one case. In three cases, possible sites of hemorrhage in the ventricles were identified. This abnormality represents a significant proportion of the fetuses examined for hydrocephalus in our referral center. We discuss the importance of careful autopsy examination in the diagnosis of cryptic intracerebral hemorrhage and the implications for counseling.

    A 33-year-old man who presented with prolonged epigastric pain was referred to our hospital. He had experienced recurrent epistaxis and had a family history of hereditary hemorrhagic telangiectasia. Computed tomography and magnetic resonance imaging revealed splenomegaly and a 9 cm hypervascular mass in his spleen. Computed tomography also showed a pulmonary arteriovenous malformation and heterogeneous enhancement of the liver parenchyma, suggesting the presence of arteriosystemic shunts and telangiectases. Based on these findings, the patient was definitely diagnosed with hereditary hemorrhagic telangiectasia according to Curaçao criteria. He underwent splenectomy, and his symptoms disappeared after surgery. Pathological examination of the resected specimen revealed that the hypervascular lesion of the spleen was not a tumor but was composed of abnormal vessels associated with hereditary hemorrhagic telangiectasia. Symptomatic splenic involvement may be a rare manifestation of hereditary hemorrhagic telangiectasia but can be revealed by imaging modalities. PMID:27807449

    1996-09-01

    Although chronic arterial hypertension is the leading cause of intracranial hemorrhage, an abrupt rise in systemic arterial pressure in normotensive people may sometimes induce a hemorrhagic stroke. Dental treatment is rarely associated with such an event. We report here on two middle-aged women, apparently healthy, who suffered from a fatal intracerebral hemorrhage following a dental treatment. On admission, high levels of arterial hypertension were found. It seems that trigeminal manipulation during dental treatment as well as increased serum levels of induced epinephrine mainly by stress and pain, and the small amounts absorbed from the site of local anesthesia might produce abrupt elevation of blood pressure, subsequent increase in cerebral blood flow and severe, even fatal intracerebral hemorrhage. The addition of catecholamines to local anesthetics should be considered. We recommend the use of benzodiazepin as a premedication drug to reduce stress during dental treatment.

    Marburg virus belongs to the genus Marburgvirus in the family Filoviridae and causes a severe hemorrhagic fever, known as Marburg hemorrhagic fever (MHF), in both humans and nonhuman primates. Similar to the more widely known Ebola hemorrhagic fever, MHF is characterized by systemic viral replication, immunosuppression and abnormal inflammatory responses. These pathological features of the disease contribute to a number of systemic dysfunctions including hemorrhages, edema, coagulation abnormalities and, ultimately, multiorgan failure and shock, often resulting in death. A detailed understanding of the pathological processes that lead to this devastating disease remains elusive, a fact that contributes to the lack of licensed vaccines or effective therapeutics. This article will review the clinical aspects of MHF and discuss the pathogenesis and possible options for diagnosis, treatment and prevention. PMID:22046196

    We report a case of bilateral orbital hemorrhage as a complication of peribulbar anesthesia in a 78 year old man. Initially, unilateral orbital hemorrhage occurred but quickly spread to the contralateral side. Neuroophthalmological assessment revealed a proptosed tense globe with normal retinovascular findings. Visual acuity was adversely affected and this was conservatively managed with no lasting ophthalmic sequela. This patient’s case was reported as it illustrates an unusual complication of bilateral spread of orbital hemorrhage secondary to peribulbar anesthesia. It highlights how early ophthalmic assessment can ensure a good visual outcome in the setting of appropriate ophthalmic monitoring. The mechanisms of orbital hemorrhage spread and appropriate management options are discussed. PMID:27013899

A retrospective analysis of the medical records of patients with suprachoroidal hemorrhages at the Instituto Universitario de Oftalmobiología Aplicada (IOBA) - University Hospital of Valladolid. Bibliographic search by Med-Line/Pub Med from 1995 to 2000 was performed. 8 patients who fulfill these criteria have been treated and 8 papers, also complying with the criteria, have been found. The functional and anatomic results of post-surgical suprachoroidal hemorrhages are still poor, even though the prognosis seems to have improved in the last 20 years. The standardized classification of massive suprachoroidal hemorrhages based on severity and the standardization of the follow-up would improve these results.

    We have recently demonstrated that acrylonitrile (VCN) causes acute gastric hemorrhage and mucosal erosions. The current studies were undertaken to investigate the effects of the sulfhydryl-containing compounds, cysteine and cysteamine, the cholinergic blocking agent atropine and the histamine H2 receptor antagonist, cimetidine on the VCN-induced gastrointestinal (GI) bleeding in rats. Our data shows that pretreatment with L-cysteine, cysteamine, atropine or cimetidine has significantly protected rats against the VCN-induced GI bleeding. A possible mechanism of the VCN-induced GI bleeding may involve the interaction of VCN with critical sulfhydryl groups that, in turn, causes alteration of acetylcholine muscarinic receptors to lead to gastric hemorrhagic lesions and bleeding.

    To estimate whether maternal obesity was associated with an increased risk for postpartum hemorrhage more than 1,000 mL and whether there was an association between maternal obesity and causes of postpartum hemorrhage and mode of delivery. A population-based cohort study including 1,114,071 women with singleton pregnancies who gave birth in Sweden from January 1, 1997 through December 31, 2008, who were divided into six body mass index (BMI) classes. Obese women (class I-III) were compared with normal-weight women concerning the risk for postpartum hemorrhage after suitable adjustments. The use of heparin-like drugs over the BMI strata was analyzed in a subgroup. There was an increased prevalence of postpartum hemorrhage over the study period associated primarily with changes in maternal characteristics. The risk of atonic uterine hemorrhage increased rapidly with increasing BMI. There was a twofold increased risk in obesity class III (1.8%). No association was found between postpartum hemorrhage with retained placenta and maternal obesity. There was an increased risk for postpartum hemorrhage for women with a BMI of 40 or higher (5.2%) after normal delivery (odds ratio [OR] 1.23, 95% confidence interval [CI] 1.04-1.45]) compared with normal-weight women (4.4%) and even more pronounced (13.6%) after instrumental delivery (OR 1.69, 95% CI 1.22-2.34) compared with normal-weight women (8.8%). Maternal obesity was a risk factor for the use of heparin-like drugs (OR 2.86, 95% CI 2.22-3.68). The increased risk for atonic postpartum hemorrhage in the obese group has important clinical implications, such as considering administration of prophylactic postpartum uterotonic drugs to this group.

    Modulating the activity of the endocannabinoid system influences various gastrointestinal physiological and pathophysiological processes, and cannabinoid receptors as well as regulatory enzymes responsible for the synthesis or degradation of endocannabinoids representing potential targets to reduce the development of gastrointestinal mucosal lesions, hemorrhage and inflammation. Direct activation of CB1 receptors by plant-derived, endogenous or synthetic cannabinoids effectively reduces both gastric acid secretion and gastric motor activity, and decreases the formation of gastric mucosal lesions induced by stress, pylorus ligation, nonsteroidal anti-inflammatory drugs (NSAIDs) or alcohol, partly by peripheral, partly by central mechanisms. Similarly, indirect activation of cannabinoid receptors through elevation of endocannabinoid levels by globally acting or peripherally restricted inhibitors of their metabolizing enzymes (FAAH, MAGL) or by inhibitors of their cellular uptake reduces the gastric mucosal lesions induced by NSAIDs in a CB1 receptor-dependent fashion. Dual inhibition of FAAH and cyclooxygenase enzymes induces protection against both NSAID-induced gastrointestinal damage and intestinal inflammation. Moreover, in intestinal inflammation direct or indirect activation of CB1 and CB2 receptors exerts also multiple beneficial effects. Namely, activation of both CB receptors was shown to ameliorate intestinal inflammation in various murine colitis models, to decrease visceral hypersensitivity and abdominal pain, as well as to reduce colitis-associated hypermotility and diarrhea. In addition, CB1 receptors suppress secretory processes and also modulate intestinal epithelial barrier functions. Thus, experimental data suggest that the endocannabinoid system represents a promising target in the treatment of inflammatory bowel diseases, and this assumption is also confirmed by preliminary clinical studies.

    Abstract Introduction: Fast-growing congenital hepatic cysts with intracystic hemorrhage are rare in clinical practice. Additionally, the clinical manifestations of and laboratory and imaging findings for this condition are often nonspecific and are particularly difficult to differentiate from those of hepatobiliary cystadenoma and cystadenocarcinoma, thus posing great challenges for diagnosis and treatment. The 2 case reports presented here aim to analyze the diagnosis and treatment of 2 rare cases of congenital hepatic cysts with intracystic hemorrhage in the Chinese Han population to provide an important reference for the clinical diagnosis and treatment of this condition. Diagnoses: These 2 case reports present 2 rare cases of congenital hepatic cysts with intracystic hemorrhage. Case 1 involved a 31-year-old patient with a very large, fast-growing hepatic cyst with intracystic hemorrhage and elevated carbohydrate antigen 199. Case 2 involved a patient with intense, paroxysmal right upper abdominal pain; computed tomography suggested a hepatic cyst with intracystic hemorrhage and possibly hepatobiliary cystadenoma. Outcomes: Both patients underwent liver resection. Postoperative follow-up showed that for both patients, the symptoms improved, the laboratory findings returned to normal levels, and the surgical outcomes were satisfactory. Conclusion: Liver resection is an ideal treatment for patients with congenital hepatic cysts with intracystic hemorrhage, and especially those with fast-growing, symptomatic hepatic cysts or hepatic cysts that are difficult to differentiate from hepatobiliary cystadenoma and cystadenocarcinoma.

    Impaired fracture healing can occur in severely injured patients with hemorrhagic shock due to decreased soft tissue perfusion after trauma. We investigated the effects of fracture healing in a standardized pressure controlled hemorrhagic shock model in mice, to test the hypothesis that bleeding is relevant in the bone healing response. Male C57/BL6 mice were subjected to a closed femoral shaft fracture stabilized by intramedullary nailing. One group was additionally subjected to pressure controlled hemorrhagic shock (HS, mean arterial pressure (MAP) of 35 mmHg for 90 minutes). Serum cytokines (IL-6, KC, MCP-1, and TNF-α) were analyzed 6 hours after shock. Fracture healing was assessed 21 days after fracture. Hemorrhagic shock is associated with a significant increase in serum inflammatory cytokines in the early phase. Histologic analysis demonstrated a significantly decreased number of osteoclasts, a decrease in bone quality, and more cartilage islands after hemorrhagic shock. μCT analysis showed a trend towards decreased bone tissue mineral density in the HS group. Mechanical testing revealed no difference in tensile failure. Our results suggest a delay in fracture healing after hemorrhagic shock. This may be due to significantly diminished osteoclast recruitment. The exact mechanisms should be studied further, particularly during earlier stages of fracture healing.

    We assessed the role of laparoscopic management in patients following spontaneous retroperitoneal hemorrhage from a renal tumor. A retrospective chart review revealed 4 patients with spontaneous retroperitoneal hemorrhage treated at our institution in the last 2 years. After conservative management elsewhere patients were referred for definitive therapy. Patient characteristics and tumor size were examined and correlated with ease of surgical dissection and surgical outcome. No patient had any history of trauma. Computerized tomography was used to identify the initial extent of hemorrhage in all patients. All patients underwent successful laparoscopic exploration without the need for open conversion. Three patients underwent radical nephrectomy and 1 underwent laparoscopic partial nephrectomy. Renal hemorrhage extending outside of the renal capsule was associated with significantly more adhesions than renal hemorrhage confined to the renal capsule. Mean patient age was 56 years (range 36 to 70). Mean retroperitoneal tumor size was 5.3 cm (range 2.5 to 10). Three renal hematomas were extracapsular and 1 was subcapsular. Mean operative time was 182.3 minutes (range 59 to 235). Average estimated blood loss was 800 cc (range 150 to 2,100). Nontraumatic retroperitoneal hemorrhage of renal origin may be managed using traditional laparoscopic techniques with results similar to those achieved with open renal exploration. These cases may prove technically challenging due to fibrosis and associated tissue plane loss.

    The concept of mucoadhesion is one that has the potential to improve the highly variable residence times experienced by drugs and dosage forms at various sites in the gastrointestinal tract, and consequently, to reduce variability and improve efficacy. Intimate contact with the mucosa should enhance absorption or improve topical therapy. A variety of approaches have been investigated for mucoadhesion in the gastrointestinal tract, particularly for the stomach and small intestine. Despite interesting results in these sites, mucoadhesive approaches have not yet shown success in humans. The potential of the lower gut for these applications has been largely neglected, although the large intestine in particular may benefit, and the colon has several factors that suggest mucoadhesion could be successful there, including lower motility and the possibility of a lower mucus turnover and thicker mucus layer. In vitro studies on colonic mucoadhesion show promise, and rectal administration has shown some positive results in vivo. This review considers the background to mucoadhesion with respect to the physiological conditions of the gastrointestinal tract as well as the principles that underlie this concept. Mucoadhesive approaches to gastrointestinal drug delivery will be examined, with particular attention given to the lower gut.

Thus, we have gained new data on microinflammation, genetics, microbiota, psychological aspects, etc. Symptoms such as abdominal distension have gained interest in the scientific community, both in terms of patients with irritable bowel syndrome and those with constipation. From the diagnostic point of view, the search continues for a biomarker for functional gastrointestinal disorders, especially for irritable bowel syndrome. In the therapeutic area, the importance of diet for these patients (FODMAP, fructans, etc.) is once again confirmed, and data is provided that backs the efficacy of already marketed drugs such as linaclotide, which rule out the use of other drugs such as mesalazine for patients with irritable bowel syndrome. This year, new forms of drug administration have been presented, including metoclopramide nasal sprays and granisetron transdermal patches for patients with gastroparesis. Lastly, a curiosity that caught our attention was the use of a vibrating capsule to stimulate gastrointestinal transit in patients with constipation.

  20. Hemorrhagic aspects of Gaucher disease.

    PubMed

    Rosenbaum, Hanna

    2014-10-01

    Gaucher disease (GD) is an inherited lysosomal disorder, originating from deficient activity of the lysosomal enzyme glucocerebrosidase (GCase). Normally, GCase hydrolyzes glucocerebroside (GC) to glucose and ceramide; however, impaired activity of this enzyme leads to the accumulation of GC in macrophages, termed "Gaucher cells." Gaucher disease is associated with hepatosplenomegaly, cytopenias, skeletal complications and in some forms involves the central nervous system. Coagulation abnormalities are common among GD patients due to impaired production and chronic consumption of coagulation factors. Bleeding phenomena are variable (as are other symptoms of GD) and include mucosal and surgical hemorrhages. FOUR MAIN ETIOLOGICAL FACTORS ACCOUNT FOR THE HEMOSTATIC DEFECT IN GD: thrombocytopenia, abnormal platelet function, reduced production of coagulation factors, and activation of fibrinolysis. Thrombocytopenia relates not only to hypersplenism and decreased megakaryopoiesis by the infiltrated bone marrow but also to immune thrombocytopenia. Autoimmunity, especially the induction of platelet antibody production, might cause persistent thrombocytopenia. Enzyme replacement therapy reverses only part of the impaired coagulation system in Gaucher disease. Other therapeutic and supportive measures should be considered to prevent and/or treat bleeding in GD. Gaucher patients should be evaluated routinely for coagulation abnormalities especially prior to surgery and dental and obstetric procedures.

    Tamoxifen is a selective estrogen receptor modulator. In this study we investigated whether or not tamoxifen reduces intracerebral hemorrhage (ICH)-induced brain injury in rats. In all experiments, adult male Sprague-Dawley rats received an injection of 100 μL autologous whole blood into the right basal ganglia. In the first set of experiments, rats were treated with tamoxifen (2.5 mg/kg or 5 mg/kg, i.p.) or vehicle 2 and 24 h after ICH and were killed at day 3 for brain edema measurement. In the second set of experiments, rats were treated with tamoxifen (5 mg/kg) or vehicle and magnetic resonance imaging (MRI), and behavior tests were performed at days 1, 7, 14 and 28. Rats were killed at day 28 for brain histology. We found that tamoxifen at 5 but not at 2.5 mg/kg reduced perihematomal brain edema at day 3 (p<0.05). Brain histology showed that tamoxifen reduced caudate atrophy at day 28 (p<0.01). Tamoxifen also improved functional outcome (p<0.05). MRI demonstrated a tendency to smaller T2* lesions in tamoxifen-treated rats. However, two out of five rats treated with tamoxifen developed hydrocephalus. These results suggest that tamoxifen has neuroprotective effects in ICH, but the cause of hydrocephalus development following tamoxifen treatment needs to be examined further.

    Bleeding from dialysis vascular access (arteriovenous fistulas, arteriovenous grafts, and vascular catheters) is uncommon. Death from these bleeds is rare and likely to be under-reported, with incident rates of fewer than 1 episode for every 1,000 patient-years on dialysis, meaning that dialysis units may experience this catastrophic event only once a decade. There is an opportunity to learn from (and therefore prevent) these bleeding deaths. We reviewed all reported episodes of death due to vascular access bleeding in Australia and New Zealand over a 14-year period together with individual dialysis units' root cause analyses on each event. In this perspective, we provide a clinically useful summary of the evidence and knowledge gained from these rare events. Our conclusion is that death due to dialysis vascular access hemorrhage is an uncommon, catastrophic, but potentially preventable event if the right policies and procedures are put in place.

    2002-05-01

    The authors present a very rare case of impaired gastric evacuation, known as Bouveret's syndrome, caused by a large biliary concrement wedged in the duodenum as a result of the development of a cholecystoduodenal fistula in a 77-year-old man. The condition was manifested clinically by developed high ileus and subsequent haemorrhage into the upper GIT. The diagnosis was established on the background of the clinical picture, passage through the upper GIT and endoscopy. As the attempt to remove the concrement endoscopically failed, laparotomy had to be used. In the conclusion of this case-record the authors discuss the method of assessment of the correct diagnosis endoscopically and possibilities of therapeutic strategy.

    A 71-year-old man presented to the emergency department with his first episode of hematemesis. He was anemic and coagulopathic on admission, and became hemodynamically unstable requiring surgical intervention to control the bleeding. Prior to surgery, he required 100% plasma exchange with human plasma derived prothrombin complex concentrate (Octaplex) as the exchange fluid. At induction of anesthesia, he received tranexamic acid, prothrombin complex concentrate, and platelets. At the time of knife to skin, he was given coagulation factor VIIa intravenously as a bolus. This treatment was on the recommendation of the hematology team who suspected a diagnosis of acquired hemophilia on the basis of his history and coagulation screen. His bleeding was controlled and a diagnosis of acquired hemophilia A was confirmed in the postoperative period. This was managed with immunosuppressive therapy, and at the 2 year follow-up he remains well and is off all treatment.

    The hospital records of 30 infants with a diagnosis of intracranial hemorrhage (ICH) due to late onset of vitamin K deficiency, seen during a 5-year period (2001-2005) were retrospectively evaluated. Signs and symptoms of the patients were convulsions (80%), poor sucking (50%), irritability (40%), vomiting (47%), acute diarrhea (33%), and fever (40%). On physical examination there were bulging or full fontanel in 19 patients (63%), collapsed fontanel in one (3%), diminished or absent neonatal reflexes in 11 (37%), pallor in 14 (47%), and cyanosis in one (3%) patient. Gastrointestinal disorder, skin hemorrhagic findings, and epistaxis each were noted in two (7%) patients. All the infants had prolonged prothrombin time (PT) and seven had prolonged activated partial thromboplastin time (APTT), both of which were corrected by the administration of vitamin K. All the infants had ICH, with the most common being intraparenchymal hemorrhage, followed by multiple type ICH (27%). Neurosurgical intervention was performed in five patients (17%). The overall case fatality rate was 33%. In conclusion, we would like to stress that ICH due to vitamin K deficiency in infants is still an important health problem in Turkey resulting in high mortality rate.

    Gangliocytic paraganglioma (GP) is an uncommon benign neurogenic tumor of the digestive tract that is usually located in the descending duodenum. Patients with GP usually present with upper gastrointestinal hemorrhage, which reflects the tendency of the tumor to ulcerate the mucosa. The authors report a patient in whom the tumor was overlooked on routine radiologic examinations and initial endoscopy. It was discovered in the distal transverse duodenum at small bowel enteroscopy. The findings of endoscopic ultrasonography are correlated with radiographic and histologic examination. 10 refs.

    We represent a case of a 54-year-old male who presented to the emergency department with right upper quadrant abdominal pain and melena three weeks after percutaneous liver biopsy. He was found to have anemia secondary to an upper gastrointestinal hemorrhage, unresponsive to multiple blood transfusions. Angiography later revealed an arteriobiliary fistula with contrast extravasation entering the duodenum. The fistula was successfully embolized and the patient was discharged without complication. This report demonstrates the importance in considering a vascular intrahepatic fistula in patients with right upper quadrant abdominal pain after remote liver biopsy.

    Intestinal barrier dysfunction remains a critical problem in patients with intracerebral hemorrhage (ICH) and is associated with poor prognosis. Ghrelin, a brain-gut peptide, has been shown to exert protection in animal models of gastrointestinal injury. However, the effect of ghrelin on intestinal barrier dysfunction post-ICH and its possible underlying mechanisms are still unknown. This study was designed to investigate whether ghrelin administration attenuates intestinal barrier dysfunction in experimental ICH using an intrastriatal autologous blood infusion mouse model. Our data showed that treatment with ghrelin markedly attenuated intestinal mucosal injury at both histomorphometric and ultrastructural levels post-ICH. Ghrelin reduced ICH-induced intestinal permeability according to fluorescein isothiocyanate conjugated-dextran (FITC-D) and Evans blue extravasation assays. Concomitantly, the intestinal tight junction-related protein markers, Zonula occludens-1 (ZO-1) and claudin-5 were upregulated by ghrelin post-ICH. Additionally, ghrelin reduced intestinal intercellular adhesion molecule-1 (ICAM-1) expression at the mRNA and protein levels following ICH. Furthermore, ghrelin suppressed the translocation of intestinal endotoxin post-ICH. These changes were accompanied by improved survival rates and an attenuation of body weight loss post-ICH. In conclusion, our results suggest that ghrelin reduced intestinal barrier dysfunction, thereby reducing mortality and weight loss, indicating that ghrelin is a potential therapeutic agent in ICH-induced intestinal barrier dysfunction therapy.

    Background and Objectives: The purpose of this study is to estimate the cumulative incidence, patient characteristics, and potential risk factors for secondary hemorrhage after total laparoscopic hysterectomy. Methods: All women who underwent total laparoscopic hysterectomy at Paul's Hospital between January 2004 and April 2012 were included in the study. Patients who had bleeding per vaginam between 24 hours and 6 weeks after primary surgery were included in the analysis. Results: A total of 1613 patients underwent total laparoscopic hysterectomy during the study period, and 21 patients had secondary hemorrhage after hysterectomy. The overall cumulative incidence of secondary hemorrhage after total laparoscopic hysterectomy was 1.3%. The mean size of the uterus was 541.4 g in the secondary hemorrhage group and 318.9 g in patients without hemorrhage, which was statistically significant. The median time interval between hysterectomy and secondary hemorrhage was 13 days. Packing was sufficient to control the bleeding in 13 patients, and 6 patients required vault suturing. Laparoscopic coagulation of the uterine artery was performed in 1 patient. Uterine artery embolization was performed twice in 1 patient to control the bleeding. Conclusions: Our data suggest that secondary hemorrhage is rare but may occur more often after total laparoscopic hysterectomy than after other hysterectomy approaches. Whether it is related to the application of thermal energy to tissues, which causes more tissue necrosis and devascularization than sharp culdotomy in abdominal and vaginal hysterectomies, is not clear. A large uterus size, excessive use of an energy source for the uterine artery, and culdotomy may play a role. PMID:25392609

    The objective was to determine whether post-tonsillectomy hemorrhages occur more frequently in redheaded children, in patterns of threes, on Friday-the-13th days, or with the full moon. Case-control analysis. The authors performed multiple statistical analyses of all children undergoing tonsillectomy at Temple University Children's Medical Center (Philadelphia, PA) during a 29-month period. Children readmitted to the hospital with or without surgical control of bleeding were compared with children who did not bleed. Relation of post-tonsillectomy hemorrhages to the phase of the moon was evaluated using a standard normal deviate. The frequency of surgery performed on Friday-the-13th days was compared with a differently dated Friday chosen at random. Clusters of three hemorrhages in a 7-day period were recorded. Families of children were contacted and asked whether their child had red hair. A chi analysis compared redheaded and non-redheaded tonsillectomy patients. Twenty-eight of 589 tonsillectomy cases performed required readmission for bleeding events. Twenty tonsillectomies occurred on a full-moon day, resulting in one bleeding event. One cluster of three post-tonsillectomy hemorrhages occurred in a 7-day period. Four of the children who bled had red hair. Two tonsillectomies occurred on Friday the 13th, with no associated hemorrhage. Statistical analysis revealed a random pattern to post-tonsillectomy hemorrhage. Post-tonsillectomy hemorrhages do not occur in clusters of three and are not more frequent with the full moon or on Friday the 13th. The bleeding rate among children with red hair is similar to that of non-redheaded children.

    Microcirculatory dysfunction has been well reported in clinical studies in septic shock. However, no clinical studies have investigated microcirculatory blood flow behavior in hemorrhagic shock. The main objective of this study was to assess the time course of sublingual microcirculation in traumatic hemorrhagic shock during the first 4 days after trauma. Prospective observational study. Eighteen traumatic hemorrhagic shock patients. The sublingual microcirculation was estimated at the study inclusion after surgical or angiographic embolization to control bleeding (D1), and then three times at 24-hour intervals (D2, D3, and D4). Sublingual microcirculation was impaired for 72 hours despite restoration of the macrovascular circulation after control of bleeding in traumatic hemorrhagic shock patients. Furthermore, we found significantly higher decreases in the microvascular flow index and proportion of perfused vessels in high Sequential Organ Failure Assessment score patients at D4 (Sequential Organ Failure Assessment score ≥ 6) compared to low Sequential Organ Failure Assessment score patients at D4 (Sequential Organ Failure Assessment score < 6) without any differences in global hemodynamics between these two groups. Finally, the initial proportion of perfused vessels at D1 appears to be a good predictor of high Sequential Organ Failure Assessment score at D4. Alterations of microcirculation in traumatic hemorrhagic shock patients result from the interplay among hemorrhage-induced tissue hypoperfusion, trauma injuries, inflammatory response, and subsequent resuscitation interventions. Despite restoration of the macrocirculation, the sublingual microcirculation was impaired for at least 72 hours. The initial proportion of perfused vessels appears to be a good predictor of high Sequential Organ Failure Assessment score at D4. Further studies are required to firmly establish the link between microvascular alterations and organ dysfunction in traumatic hemorrhagic

    Sudden hearing deterioration may occur in our population, but it is difficult to explain the exact pathophysiology and the cause. Magnetic resonance imaging (MRI) in sudden sensorineural hearing loss (SSNHL) is usually useful to evaluate neural lesions such as acoustic schwannoma and hemorrhage in labyrinth. Recently some cases of SSNHL caused by intralabyrintine hemorrhage were reported by the advance of MRI. In the case of intralabyrintine hemorrhage, MRI showed a hyperintense signal in the labyrinth on the pre-contrast and contrast enhanced T1-weighted image and relatively weak intensity on T2-weighted image. The prognosis SSNHL by intralabyrintine hemorrhage is generally known to be poor. We report a case of sudden deafness with intralabyrintine hemorrhage who has a history of anticoagulant administration, with a review of literature. PMID:26771018

    Hemorrhage represents the most feared complication of cerebral arteriovenous malformations (AVMs) in both untreated patients and those treated with gamma knife radiosurgery. Radiosurgery does not immediately lead to obliteration of the malformation, which often does not occur until years following treatment. Post-obliteration hemorrhage is rare, occurring months to years after radiosurgery, and has been associated with residual or recurrent AVM despite prior apparent nidus elimination. Three cases are reported of delayed intracranial hemorrhage in patients with cerebral AVMs treated with radiosurgery in which no residual AVM was found on catheter angiography at the time of delayed post-treatment hemorrhage. That the pathophysiology of these hemorrhages involves progressive venous outflow occlusion is speculated and the possible mechanistic link to subsequent vascular rupture is discussed.

    Hemorrhage is known to occur in posterior reversible encephalopathy syndrome (PRES), but the characteristics have not been analyzed in detail. The purpose of this study was to evaluate the imaging and clinical features of hemorrhage in PRES. Retrospective assessment of 151 patients with PRES was performed, and 23 patients were identified who had intracranial hemorrhage at toxicity. Hemorrhage types were identified and tabulated, including minute focal hemorrhages (<5 mm), sulcal subarachnoid hemorrhage, and focal hematoma. Clinical features of hemorrhage and nonhemorrhage PRES groups were evaluated, including toxicity blood pressure, coagulation profile/platelet counts, coagulation-altering medication, and clinical conditions associated with PRES. Toxicity mean arterial pressure (MAP) groups were defined as normal (<106 mm Hg), mildly hypertensive (106-116 mm Hg), or severely hypertensive (>116 mm Hg). The overall incidence of hemorrhage was 15.2%, with borderline statistical significance noted between the observed clinical associations (P = .07). Hemorrhage was significantly more common (P = .02) after allogeneic bone marrow transplantation (allo-BMT) than after solid-organ transplantation. The 3 hemorrhage types were noted with equal frequency. A single hemorrhage type was found in 16 patients, with multiple types noted in 7. Patients undergoing therapeutic anticoagulation were statistically more likely to develop hemorrhage (P = .04). No difference in hemorrhage incidence was found among the 3 blood pressure subgroups (range, 14.9%-15.9%). Three distinct types of hemorrhage (minute hemorrhage, sulcal subarachnoid hemorrhage, hematoma) were identified in PRES with equal frequency. The greatest hemorrhage frequency was seen after allo-BMT and in patients undergoing therapeutic anticoagulation. Hemorrhage rate was independent of the toxicity blood pressure.

    2017-01-01

    Abstract Rationale: We are reporting the first-to our knowledge-case of duodenal Plexiform Fibromyxoma causing obscure upper gastrointestinal bleeding. Patient concerns: Plexiform fibromyxoma triggered recurrent upper gastrointestinal bleeding episodes in a 63-year-old man who remained undiagnosed, despite multiple hospitalizations, extensive diagnostic workups and surgical interventions (including gastrectomies), for almost 17 years. Diagnoses-Interventions: During hospitalization for the last bleeding episode, an upper gastrointestinal endoscopy revealed an intestinal hemorrhagic nodule. The lesion was deemed unresectable by endoscopic means. An abdominal computerized tomography disclosed no further lesions and surgery was decided. The lesion at operation was found near the edge of the duodenal stump and treated with pancreas-preserving duodenectomy (1st and 2nd portion). Outcomes: Postoperative recovery was mainly uneventful and a 20-month follow-up finds the patient in good health with no need for blood transfusions. Plexiform fibromyxomas stand for a rare and widely unknown mesenchymal entity. Despite the fact that they closely resemble other gastrointestinal tumors, they distinctly vary in clinical management as well as the histopathology. Clinical awareness and further research are compulsory to elucidate its clinical course and prognosis. PMID:28072751

    Diffusion Tensor Imaging (DTI) has evolved considerably over the last decade to now be knocking on the doors of wider clinical applications. There have been several efforts over the last decade to seek valuable and reliable application of DTI in different neurological disorders. The role of DTI in predicting outcomes in patients with brain tumors has been extensively studied and has become a fairly established clinical tool in this scenario. More recently DTI has been applied in mild traumatic brain injury to predict clinical outcomes based on DTI of the white matter tracts. The resolution of white matter fiber tractography based on DTI has improved over the years with increased magnet strength and better tractography post processing. The role of DTI in hemorrhagic stroke has been studied preliminarily in the scientific literature. There is some evidence that DTI may be efficacious in predicting outcomes of motor function in animal models of intracranial hemorrhage. Only a handful of studies of DTI have been performed in subarachnoid hemorrhage or intraventricular hemorrhage scenarios. In this manuscript we will review the evolution of DTI, the existing evidence for its role in hemorrhagic stroke and discuss possible application of this non-invasive evaluation technique of human cerebral white matter tracts in the future.

    Objective Hemorrhagic cystitis is a challenging clinical entity with limited evidence available to guide treatment. The use of intravesical silver nitrate has been reported, though supporting literature is sparse. Here, we sought to assess outcomes of patients treated with intravesical silver nitrate for refractory hemorrhagic cystitis. Material and methods We identified nine patients with refractory hemorrhagic cystitis treated at our institution with intravesical silver nitrate between 2000–2015. All patients had failed previous continuous bladder irrigation with normal saline and clot evacuation. Treatment success was defined as requiring no additional therapy beyond normal saline irrigation after silver nitrate instillation prior to hospital discharge. Results Median patient age was 80 years (IQR 73, 82). Radiation was the most common etiology for hemorrhagic cystitis 89% (8/9). Two patients underwent high dose (0.1%–0.4%) silver nitrate under anesthesia, while the remaining seven were treated with doses from 0.01% to 0.1% via continuous bladder irrigation for a median of 3 days (range 2–4). All nine patients (100%) had persistent hematuria despite intravesical silver nitrate therapy, requiring additional interventions and red blood cell transfusion during the hospitalization. There were no identified complications related to intravesical silver nitrate instillation. Conclusion Although well tolerated, we found that intravesical silver nitrate was ineffective for bleeding control, suggesting a limited role for this agent in the management of patients with hemorrhagic cystitis.

    2011-11-01

    A number of concerns have been raised regarding the advisability of the classic principles of aggressive crystalloid resuscitation in traumatic hemorrhagic shock. This issue reviews the advances that have led to a shift in the emergency department (ED) protocols in resuscitation from shock state, including recent literature regarding the new paradigm for the treatment of traumatic hemorrhagic shock, which is most generally known as damage control resuscitation (DCR). Goals and endpoints for resuscitation and a review of initial fluid choice are discussed, along with the coagulopathy of trauma and its management, how to address hemorrhagic shock in traumatic brain injury (TBI), and new pharmacologic treatment for hemorrhagic shock. The primary conclusions include the administration of tranexamic acid (TXA) for all patients with uncontrolled hemorrhage (Class I), the implementation of a massive transfusion protocol (MTP) with fixed blood product ratios (Class II), avoidance of large-volume crystalloid resuscitation (Class III), and appropriate usage of permissive hypotension (Class III). The choice of fluid for initial resuscitation has not been shown to affect outcomes in trauma (Class I).

    The rapidly moving technological advances in gastrointestinal endoscopy have enhanced an endoscopist’s ability to diagnose and treat lesions within the gastrointestinal tract. The improvement in image quality created by the advent of high-definition and magnification endoscopy, alongside image enhancement, produces images of superb quality and detail that empower the endoscopist to identify important lesions that have previously been undetectable. Additionally, we are now seeing technologies emerge, such as optical coherence tomography and confocal laser endomicroscopy, that allow the endoscopist to visualize individual cells on a microscopic level and provide a real time, in vivo histological assessment. Within this article we discuss these technologies, as well as some of the results from their early use in clinical studies. PMID:26918137

    We analyzed the Mexican legal framework, identifying the vectors that characterize quality and control in gastrointestinal surgery. Quality is contemplated in the health protection rights determined according to the Mexican Constitution, established in the general health law and included as a specific goal in the actual National Development Plan and Health Sector Plan. Quality control implies planning, verification and application of corrective measures. Mexico has implemented several quality strategies such as certification of hospitals and regulatory agreements by the General Salubrity Council, creation of the National Health Quality Committee, generation of Clinical Practice Guidelines and the Certification of Medical Specialties, among others. Quality control in gastrointestinal surgery must begin at the time of medical education and continue during professional activities of surgeons, encouraging multidisciplinary teamwork, knowledge, abilities, attitudes, values and skills that promote homogeneous, safe and quality health services for the Mexican population.

    The amino acid glutamine has become one of the most intensively studied nutrients in the field of nutrition and metabolic support. A variety of studies in cell culture systems, animal models of gut mucosal atrophy, injury/repair and adaptation and a limited number of clinical trials demonstrate trophic and cytoprotective effects of glutamine in small bowel and colonic mucosal cells. Although the routine clinical use of glutamine-enriched parenteral and enteral nutrient solutions remains controversial, available data demonstrate both the safety and metabolic and clinical efficacy of glutamine treatment in selected patient groups. Basic investigations are elucidating underlying mechanisms of glutamine action in intestinal cells. These will inform preclinical and clinical investigations designed to determine glutamine efficacy in selected gastrointestinal disorders. Emerging clinical trials will further define the utility of adjunctive glutamine supplementation as a component of specialized nutrition support in gastrointestinal disease.

    Subclinical gut inflammation has been described in up to two-thirds of patients with spondyloarthropathies (SpA). Arthritis represents an extra-intestinal manifestation of several gastrointestinal diseases, including inflammatory bowel disease (IBD), Whipple’s disease, Behcet’s disease, celiac disease, intestinal bypass surgery, parasitic infections of the gut and pseudomembranous colitis. Moreover about two-thirds of nonsteroidal anti-inflammatory drug users demonstrate intestinal inflammation. Arthritis may manifest as a peripheral or axial arthritis. The spondyloarthropathy family consists of the following entities: ankylosing spondylitis, undifferentiated spondyloarthritis, reactive arthritis, psoriatic arthritis, spondyloarthritis associated with IBD, juvenile onset spondyloarthritis. This topic reviews the major gastrointestinal manifestations that can occur in patients with SpA and in nonsteroidal anti-inflammatory drugs users. PMID:19468992

    It has been demonstrated recently in several solid tumors that thrombocytosis at diagnosis may correlate with tumor invasion, metastatic progression and worse outcome. Several details of the pathomechanism of the relationship of thrombocytosis and cancer have been elucidated; however, the complete process is not clearly understood. Several hypotheses have been proposed. Recently, it was suggested that in ovarian cancer elevated IL-6 production by the tumor may induce increased megakaryopoiesis via hepatic thrombopoietin production leading to thrombocytosis. The importance of the prognostic power of elevated platelet count is still debated in gastrointestinal cancer. The aims of this review were to evaluate the prognostic significance of thrombocytosis in gastrointestinal tumors, to see whether clinical practice confirmed the hypotheses and to reveal the causes of the inconsistent findings.

    Nordic research on physiology and pathophysiology of the upper gastrointestinal tract has flourished during the last 50 years. Swedish surgeons and physiologists were in the frontline of research on the regulation of gastric acid secretion. This research finally led to the development of omeprazole, the first proton pump inhibitor. When Swedish physiologists developed methods allowing the assessment of acid secretion in isolated oxyntic glands and isolated parietal cells, the understanding of mechanisms by which gastric acid secretion is regulated took a great step forward. Similarly, in Trondheim, Norway, the acid producing isolated rat stomach model combined with a sensitive and specific method for determination of histamine made it possible to evaluate this regulation qualitatively as well as quantitatively. In Lund, Sweden, the identification of the enterochromaffin-like cell as the cell taking part in the regulation of acid secretion by producing and releasing histamine was of fundamental importance both physiologically and clinically. Jorpes and Mutt established a center at Karolinska Institutet in Stockholm for the purification of gastrointestinal hormones in the 1960s, and Danes followed up this work by excelling in the field of determination and assessment of biological role of gastrointestinal hormones. A Finnish group was for a long period in the forefront of research on gastritis, and the authors' own studies on the classification of gastric cancer and the role of gastrin in the development of gastric neoplasia are of importance. It can, accordingly, be concluded that Nordic researchers have been central in the research on area of the upper gastrointestinal physiology and diseases.

    Cysteine and serine proteases are involved in cancer invasion and metastasis. In the past few years we investigated the tissue levels of these proteases in gastric cancer (GC), gastric precancerous changes (CAG), colorectal cancer (CRC) and the plasma and serum levels of proteases in several gastrointestinal tumours, using ELISA methods. Significantly higher antigen levels were found not only in GC tissue but also in CAG with respect to the levels found normal tissue; with respect to CAG, patients with dysplasia had higher levels than patients without dysplasia. The same findings were obtained in CRC. In general protease levels correlated with the major histomorphological parameters, such as grading and histotype in GC as well as in CRC. Tissue protease levels had a strong prognostic impact in GC, in which UPA was singled out by multivariate analysis as the major prognostic factor, and CRC. The plasma levels of urokinase-type plasminogen activator (UPA) and the serum levels of cathepsin B were significantly increased in patients with gastrointestinal tumours. In conclusions, cysteine and serine proteases may have a part not only in GC and CRC invasion and metastasis, but also in the progression of gastric precancerous changes into cancer. They are strong prognostic factors in GC and CRC. These proteases may also have a role as tumour markers in the early diagnosis of gastrointestinal tract tumours.

    2015-01-01

    Diet is believed to modulate cancer risk and this relationship has been widely studied in the gastrointestinal tract. Observational epidemiologic studies have provided most of the evidence for the effects of diet on cancer risk, because clinical trials to determine nutritional exposures are often impossible, impractical, or unaffordable. Although a few foods or nutrients are thought to protect against specific types of cancer, it seems clear that the strength and even direction of dietary associations (increasing or decreasing risk) is organ site- and even histology-specific, along the gastrointestinal tract. Although some hypotheses are supported by a substantial body of observational data (drinking hot maté contributes to esophageal cancer), there is not much data to support others. We discuss some highly touted hypotheses and draw interim conclusions about what is known, and what could be done to improve the level of evidence. The complex nature of diet and its associations can be productively investigated with disease-specific studies. However, public health recommendations for normal-risk individuals regarding diet and gastrointestinal cancer should probably emphasize the importance of eating for overall health, rather than eating specific foods to reduce risk for specific cancers.

    Collagen vascular diseases are known to present with a diverse array of gastrointestinal manifestations. These can be classified as: 1) gastrointestinal damage due to the collagen vascular disease itself; 2) adverse events caused by pharmacotherapies; or 3) gastrointestinal infections following immunosuppression due to corticosteroid (CS) administration. The first group includes lupus enteritis and protein-losing gastroenteropathy in systemic lupus erythematosus (SLE), reflux esophagitis, chronic intestinal pseudo-obstruction, and pneumatosis cystoids intestinalis in systemic sclerosis, amyloidosis in rheumatoid arthritis, bowel ulcer and bleeding in rheumatoid vasculitis and microscopic polyangiitis, and ileocecal ulcer in Behcet disease. In particular, colonic ulcers associated with SLE represent refractory lesions resistant to CS. Analysis of reported cases showing colonic lesions with SLE (22 cases in Japan) revealed that mean duration of SLE was 9.9 years and 77% of colonic lesions were observed in the rectum and sigmoid colon. Half of the patients developed intestinal perforation or penetration, and 6 of the 11 patients with perforation died. The second group includes lesions in the small and large intestine due to nonsteroidal anti-inflammatory drugs (NSAIDs) and CSs, in addition to peptic ulcers. As perforation in CS-treated patients displays relatively high incidence with poor prognosis, careful attention to such complications is needed. The third group includes candidal esophagitis and cytomegalovirus (CMV) enteritis. Prompt diagnosis is required to prevent colonic bleeding and perforation due to CMV.

    Reversible cerebral vasoconstriction syndrome (RCVS) is characterized by sudden-onset headache with focal neurologic deficit and prolonged but reversible multifocal narrowing of the distal cerebral arteries. Stroke, either hemorrhagic or ischemic, is a relatively frequent presentation in RCVS, but progressive manifestations of subarachnoid hemorrhage, intracerebral hemorrhage, cerebral infarction in a patient is seldom described. We report a rare case of a 56-year-old woman with reversible cerebral vasoconstriction syndrome consecutively presenting as cortical subarachnoid hemorrhage, intracerebral hemorrhage, and cerebral infarction. When she complained of severe headache with subtle cortical subarachnoid hemorrhage, her angiography was non-specific. But, computed tomographic angiography showed typical angiographic features of this syndrome after four days. Day 12, she suffered mental deterioration and hemiplegia due to contralateral intracerebral hematoma, and she was surgically treated. For recurrent attacks of headache, medical management with calcium channel blockers has been instituted. Normalized angiographic features were documented after 8 weeks. Reversible cerebral vasoconstriction syndrome should be considered as differential diagnosis of non-aneurysmal subarachnoid hemorrhage, and repeated angiography is recommended for the diagnosis of this under-recognized syndrome.

Herein, we reported a 28-year-old female patient with a cerebellar dermoid cyst, which was found accidently on neuro-imaging after head trauma. MR scanning revealed that the lesion was located within the cerebellar vermis and was measured 3.5cm×3.9cm×3.0cm, with hyper-intensity on T1WI and hypo-intensity on T2WI. However, on CT imaging, it showed hyper-dense signals. It was removed completely via midline sub-occipital approach under surgical microscope. Histological examination proved it was a dermoid cyst with internal hemorrhage. In combination with literature review, we discussed the factors that might be responsible for the hemorrhage within dermoid cysts. PMID:22211083

Chronic femoral arterial (for measurement of mean arterial pressure - MAP) and venous (for drug infusion) catheters were implanted at least 5 days before experimentation. Hem was administered in < 2 min. 10 rats (CTL) were exposed to a total of 21 episodes of hemorrhage. 13 rats (B-block) were given 1 mg/kg propranolol hydrochloride iv 20 min prior to hem (24 episodes total). Plasma renin activity (PRA) was measured by radioimmunoassay. Pre-hem PRA levels were measured in the first 1 ml of hem blood. Hem resulted in hem volume-dependent decreases in blood pressure and increase-response to hemorrhage.

    The present paper establishes a narrative and analytical review of diffuse alveolar hemorrhage (DAH) in ANCA-associated vasculitis, systemic lupus erythematosus, and antiphospholipid syndrome. Recent studies found a frequent association between DAH and infections and systemic lupus erythematosus and its associated factors. Biological therapies like rituximab have demonstrated benefit mainly in patients with ANCA-associated vasculitis. Main clinical manifestations of diffuse alveolar hemorrhage in these three diseases include dyspnea, pulmonary infiltrates, cough, and hypoxemia. The presence of hemorrhagic bronchoalveolar lavage, hemosiderin containing macrophages, or an increase of carbon monoxide diffusing capacity have been described in some series as helpful findings for the diagnosis. Hemoptysis has been seen mainly in systemic lupus erythematosus. The cornerstone of therapy includes glucocorticoids and cyclophosphamide, and recent findings in ANCA-associated vasculitis suggest the similar benefit of rituximab. Future evaluations and systematic reviews will help to define the real benefit for therapies that appeared to be controversial at the moment.

    Post-clipping intraparenchymal hemorrhage of the contralateral hemisphere is a very unusual phenomenon in a patient with aneurysmal subarachnoid hemorrhage, unless there is an underlying condition. We report a complicated case of 47-year-old man, who underwent uneventful clipping of ruptured aneurysm and experienced vasospasm two weeks later. Vasospasm was treated by intra-arterial nimodipine and systemic hyperdynamic therapy. One week thereafter, he became unconscious due to intraparenchymal hemorrhage on the anterior border-zone of contalateral hemisphere, but intraoperative and pathologic findings failed to disclose any vascular anomaly. We suggest that the anti-spastic regimens cause local hemodynamic redistribution through the vasodilatory effect and in turn, resulted in such an unexpected bleeding. PMID:19096626

    Colloid cysts are benign slow-growing cystic lesions located on the roof of the third ventricle that usually present with symptoms related to gradual rise of intracranial pressure. They mostly remain asymptomatic and sometimes grow progressively and cause diverse symptoms associated with increased intracranial pressure such as headache, diplopia, and sixth cranial nerve palsy. Here we report a 47-year-old female who presented to the emergency department with acute severe headache and nausea/vomiting. On MRI examination acute hydrocephaly due to hemorrhagic colloid cyst was detected. Acute hemorrhage in colloid cysts is extremely rare and may present with symptoms of acute increase in the intracranial pressure. Intracystic hemorrhage is very rarely reported as a complication of colloid cyst presenting with paroxysmal symptoms of acute hydrocephaly. PMID:28210514

    Lichen sclerosus is a chronic inflammatory disease, usually located in the genital area. The etiology of lichen sclerosus is multifactorial, with participation of genetic, autoimmune, infectious and hormonal factors. Bullous clinical form stems from hydropic degeneration of the basal membrane, constituting a less frequent variant of the disease. In this work, we report the case of a female patient, 55 years old, who in the last three years presented whitish plaques, with horny spikes, located on back and arms. Some of these lesions evolved with hemorrhagic blisters, which after histopathological examination confirmed the diagnosis of bullous and hemorrhagic lichen sclerosus. The patient was treated with high-potency topical corticosteroid for two months, resulting in remission of bullous and hemorrhagic lesions. PMID:26312692

    Neuropeptide Y (NPY) is one of the most potent endogenous vasoconstrictors, and its contribution to the multifactorial cascade of cerebral vasospasm due to nontraumatic subarachnoid hemorrhage (SAH) is not yet fully understood. This experimental study compared the hemorrhage-specific course of NPY secretion into cerebrospinal fluid (CSF) and into plasma between 2 groups: patients with SAH and patients with basal ganglia hemorrhage (BGH) or cerebellar hemorrhage (CH) over the first 10 days after hemorrhage. Seventy-nine patients were prospectively included: SAH patients (n=66) (historic population) and intracerebral hemorrhage patients (n=13). All patients received an external ventricular drain within 24 hours of the onset of bleeding. CSF and plasma were drawn daily from day 1 to day 10. The levels of NPY were determined by means of competitive enzyme immunoassay. The CSF samples of 29 patients (historic population) who had undergone spinal anesthesia due to orthopedic surgery served as the control group. NPY levels in CSF were significantly higher in the 2 hemorrhage groups than in the control group. However, the 2 hemorrhage groups showed significant differences in NPY levels in CSF (SAH mean, 0.842 ng/mL vs. BGH/CH mean, 0.250 ng/mL; P<0.001) as well as in the course of NPY secretion into CSF over the 10-day period. NPY levels in plasma did not differ significantly among SAH, BGH/CH, and controls. Our findings support the hypothesis that excessive release of NPY into CSF but not into plasma is specific to aneurysmal SAH in the acute period of 10 days after hemorrhage. In BGH/CH, CSF levels of NPY were also increased, but the range was much lower.

    With advancing technology, the sensitivity of computed tomography (CT) for the detection of traumatic subarachnoid hemorrhage (tSAH) continues to improve. Increased resolution has allowed for the detection of hemorrhage that is limited to one or two images of the CT exam. At our institution, all patients with a SAH require intensive care unit (ICU) admission, regardless of size. It was our hypothesis that patients with small subarachnoid hemorrhage experience favorable outcomes, and may not require the intensive monitoring offered in the ICU. This retrospective study evaluated 62 patients between 2011 and 2014 who presented to our Level I trauma center emergency room for acute traumatic injuries, and found to have subarachnoid hemorrhages on CT examination. The grade of subarachnoid hemorrhage was determined using previously utilized scoring systems, such as the Fisher, Modified Fisher, and Claassen grading systems. Electronic medical records were used to evaluate for medical decline, neurological decline, neurosurgical intervention, and overall hospital course. Admitting co-morbidities were noted, as were the presence of patient intoxication and use of anticoagulants. Patient outcomes were based on discharge summaries upon which the neurological status of the patient was assessed. Each patient was given a score based on the Glasgow outcome scale. The clinical and imaging profile of 62 patients with traumatic SAH were studied. Of the 62 patients, 0 % underwent neurosurgical intervention, 6.5 % had calvarial fractures, 25.8 % had additional intracranial hemorrhages, 27.4 % of the patients had significant co-morbidities, and 1.6 % of the patients expired. Patients with low-grade tSAH spent less time in the ICU, demonstrated neurological and medical stability during hospitalization. None of the patients with low-grade SAH experienced seizure during their admission. In our study, patients with low-grade tSAH demonstrated favorable clinical outcomes. This suggests

    Hemorrhagic shock is generally characterized by hemodynamic instability with cellular hypoxia and diminishing cellular function, resulting from an imbalance between systemic oxygen delivery and consumption and redistribution of fluid and electrolytes. Magnesium (Mg) is the fourth most abundant cation overall and second most abundant intracellular cation in the body and an essential cofactor for the energy production and cellular metabolism. Data for blood total Mg (tMg; free-ionized, protein-bound, and anion-bound forms) and free Mg(2+) levels after a traumatic injury are inconsistent and only limited information is available on hemorrhagic effects on free Mg(2+) as the physiologically active form. The aim of this study was to determine changes in blood Mg(2+) and tMg after hemorrhage in rats identifying mechanism and origin of the changes in blood Mg(2+). Hemorrhagic shock produced significant increases in blood Mg(2+), plasma tMg, Na(+), K(+), Cl(-), anion gap, partial pressures of oxygen, glucose, and blood urea nitrogen but significant decreases in RBC tMg, blood Ca(2+), HCO3(-), pH, partial pressures of carbon dioxide, hematocrit, hemoglobin, total cholesterol, and plasma/RBC ATP. During hemorrhagic shock, K(+), anion gap, and BUN showed significant positive correlations with changes in blood Mg(2+) level, while Ca(2+), pH, and T-CHO correlated to Mg(2+) in a negative manner. In conclusion, hemorrhagic shock induced an increase in both blood-free Mg(2+) and tMg, resulted from Mg(2+) efflux from metabolic damaged cell with acidosis and ATP depletion.

  6. Cannabinoids and the gastrointestinal tract

    PubMed Central

    PERTWEE, R

    2001-01-01

    The enteric nervous system of several species, including the mouse, rat, guinea pig and humans, contains cannabinoid CB1 receptors that depress gastrointestinal motility, mainly by inhibiting ongoing contractile transmitter release. Signs of this depressant effect are, in the whole organism, delayed gastric emptying and inhibition of the transit of non-absorbable markers through the small intestine and, in isolated strips of ileal tissue, inhibition of evoked acetylcholine release, peristalsis, and cholinergic and non-adrenergic non-cholinergic (NANC) contractions of longitudinal or circular smooth muscle. These are contractions evoked electrically or by agents that are thought to stimulate contractile transmitter release either in tissue taken from morphine pretreated animals (naloxone) or in unpretreated tissue (γ-aminobutyric acid and 5-hydroxytryptamine). The inhibitory effects of cannabinoid receptor agonists on gastric emptying and intestinal transit are mediated to some extent by CB1 receptors in the brain as well as by enteric CB1 receptors. Gastric acid secretion is also inhibited in response to CB1 receptor activation, although the detailed underlying mechanism has yet to be elucidated. Cannabinoid receptor agonists delay gastric emptying in humans as well as in rodents and probably also inhibit human gastric acid secretion. Cannabinoid pretreatment induces tolerance to the inhibitory effects of cannabinoid receptor agonists on gastrointestinal motility. Findings that the CB1 selective antagonist/inverse agonist SR141716A produces in vivo and in vitro signs of increased motility of rodent small intestine probably reflect the presence in the enteric nervous system of a population of CB1 receptors that are precoupled to their effector mechanisms. SR141716A has been reported not to behave in this manner in the myenteric plexus-longitudinal muscle preparation (MPLM) of human ileum unless this has first been rendered cannabinoid tolerant. Nor has it been

    Automated hemorrhage detection and segmentation in traumatic pelvic injuries is vital for fast and accurate treatment decision making. Hemorrhage is the main cause of deaths in patients within first 24 hours after the injury. It is very time consuming for physicians to analyze all Computed Tomography (CT) images manually. As time is crucial in emergence medicine, analyzing medical images manually delays the decision-making process. Automated hemorrhage detection and segmentation can significantly help physicians to analyze these images and make fast and accurate decisions. Hemorrhage segmentation is a crucial step in the accurate diagnosis and treatment decision-making process. This paper presents a novel rule-based hemorrhage segmentation technique that utilizes pelvic anatomical information to segment hemorrhage accurately. An evaluation measure is used to quantify the accuracy of hemorrhage segmentation. The results show that the proposed method is able to segment hemorrhage very well, and the results are promising.

    Intracerebral hemorrhage (ICH) is a common and often fatal subtype of stroke and produces severe neurological deficits in survivors. At present, there is lack of effective treatments that improve outcome in ICH. A neglected aspect of ICH research is the development of approaches that can be effectively used to improve recovery. Although previous studies have showed that thrombin induces blood-brain barrier leakage, brain edema and neuronal death after intracerebral hemorrhage (ICH), our recent studies have shown that thrombin may have a role in brain recovery after ICH. An understanding of the mechanisms by which thrombin affects neurogenesis, angiogenesis and plasticity may facilitate brain recovery after ICH. PMID:19064789

    Subarachnoid hemorrhage is a serious neurological disorder that is often complicated by the occurrence of electrocardiographic abnormalities unexplained by preexisting cardiac conditions. These morphological waveform changes and arrhythmias often are unrecognized or misinterpreted, potentially placing patients at risk for inappropriate management. Many previous investigations were retrospective and relied on data collected in an unsystematic manner. More recent studies that included use of serial electrocardiograms and Holter recordings have provided new insight into the high prevalence of electrocardiographic changes in subarachnoid hemorrhage. Research on the prevalence, duration, and clinical significance of these electrocardiographic abnormalities and on associated factors and etiological theories is reviewed.

    We report a peculiar case of hemorrhagic pellagra in an exhausted Albanian refugee who had walked for 3 days under sunny skies on his way from his country to Greece. The peculiarities of the case are the fulminant course of the disorder; the "terrifying" appearance of the patient (initially he was admitted to an emergency unit); the gangrenous appearance of the hemorrhagic lesions of the palms and fingernails; the disturbed hepatic function that gradually returned to normal; and the absence of a history of alcohol consumption, alcohol malabsorption, or drug intake.

  12. Hemorrhagic unilateral moyamoya: report of one case.

    2004-06-01

    A 29 year old woman presented with an intracerebral hemorrhage. Angiographic findings were consistent with unilateral moyamoya. The patient was managed non-surgically and discharged with the indication of periodical followup angiography. Moyamoya is a rare entity that must be considered in the differential diagnosis of ischemic or hemorrhagic cerebrovascular events. At present, the natural history of unilateral moyamoya is not well established in relation to the progression to a bilateral form and to rebleeding risk. Periodical follow-up angiography (conventional or MRI) seems a reasonable management strategy.

    A 50-year-old man presented with progressive visual loss, headache, and two days of confusion. A computed tomography of his head suggested subarachnoid hemorrhage with accompanying right parietal ischemic infarction. The magnetic resonance image was consistent with right parietal perisulcal pial and superficial cortical inflammation; a subjacent vasogenic edema with a 1 cm diameter abscess was also present. Funduscopy revealed bilateral multifocal choroidal lesions and retinal perivascular sheathing. He was diagnosed with pseudosubarachnoid hemorrhage secondary to cryptococcal meningitis and choroidal microabscesses with retinal inflammation after a cerebrospinal fluid (CSF) examination revealed cryptococcal yeast forms, as well as high titers of CSF cryptococcal antigen, but no CSF red blood cells.

    The adrenal hemorrhage is a relatively rare event in newborns but must be considered in the presence of a persistent unexplained jaundice, especially in presence of predisposing factors. Serial ultrasonography is the modality of choice for initial diagnosis and follow-up of neonatal adrenal hemorrhage. We report two cases of neonatal adrenal hemorrhage presenting with persistent jaundice. The causes of the neonatal adrenal hemorrhages were a difficult vaginal delivery in macrosomic infant and a neonatal infection.

    Background Iron deficiency anemia remains a major global health problem. Higher iron demands provide the potential for a targeted preventative approach before anemia develops. The primary study objective was to develop and validate a metric that stratifies recommended dietary iron intake to compensate for patient-specific non-menstrual hemorrhagic losses. The secondary objective was to examine whether iron deficiency can be attributed to under-replacement of epistaxis (nosebleed) hemorrhagic iron losses in hereditary hemorrhagic telangiectasia (HHT). Methodology/Principal Findings The hemorrhage adjusted iron requirement (HAIR) sums the recommended dietary allowance, and iron required to replace additional quantified hemorrhagic losses, based on the pre-menopausal increment to compensate for menstrual losses (formula provided). In a study population of 50 HHT patients completing concurrent dietary and nosebleed questionnaires, 43/50 (86%) met their recommended dietary allowance, but only 10/50 (20%) met their HAIR. Higher HAIR was a powerful predictor of lower hemoglobin (p = 0.009), lower mean corpuscular hemoglobin content (p<0.001), lower log-transformed serum iron (p = 0.009), and higher log-transformed red cell distribution width (p<0.001). There was no evidence of generalised abnormalities in iron handling Ferritin and ferritin2 explained 60% of the hepcidin variance (p<0.001), and the mean hepcidinferritin ratio was similar to reported controls. Iron supplement use increased the proportion of individuals meeting their HAIR, and blunted associations between HAIR and hematinic indices. Once adjusted for supplement use however, reciprocal relationships between HAIR and hemoglobin/serum iron persisted. Of 568 individuals using iron tablets, most reported problems completing the course. For patients with hereditary hemorrhagic telangiectasia, persistent anemia was reported three-times more frequently if iron tablets caused diarrhea or needed to be stopped

    Purpose To report bilateral hemorrhagic retinopathy in an adult female following lumbar spinal surgery and seizure. Case Report A 38 year old female presented with bilateral blurry vision and spots in the visual field. The patient had lumbar spondylosis surgery which was complicated by a dural tear with persistent cerebrospinal fluid leak. Visual symptoms started immediately following witnessed seizure-like activity. At presentation, visual acuity was 20/100 and 20/25 in the right and left eye, respectively. Dilated fundus examination demonstrated bilateral hemorrhagic retinopathy with subhyaloid, intraretinal and subretinal involvement. At 4 month follow up, visual acuity improved to 20/60 and 20/20 in the right and left eye, respectively. Dilated fundus examination and fundus photography showed resolution of retinal hemorrhages in both eyes. Conclusions The first case of bilateral hemorrhagic retinopathy following lumbar spondylosis surgery and witnessed seizure in an adult was reported. Ophthalmic examination may be warranted following episodes of seizure in adults. PMID:26099062

    To describe cases of obstetric hemorrhage that have called for selective intra-arterial embolization and the different embolization techniques used. To assess the clinical outcomes and postprocedural fertility. We studied 27 women with obstetric hemorrhage. In 24 patients, embolization was performed by catheterizing both uterine arteries and in 2 patients only one uterine artery was catheterized (pseudoaneurysm). The materials used for embolization consisted of Spongostan in 17/27, particles in 9/27, and coils in 1/27. Clinical follow-up included an analysis of early and late complications and of postprocedural fertility. Hemorrhage was classified as primary (25/27) or secondary (2/27). The cause of bleeding was vaginal delivery (20), cesarean sections (5), abortion (1), and cervical ectopic pregnancy (1). The initial technical success rate was 100% and the clinical success rate was 92.6% (25 of the 27 patients). Bleeding ceased and the outcome was satisfactory in 25 patients. During clinical follow-up ranging from one to seven years, 23 patients had normal menstruation and 6 patients completed 7 full-term pregnancies. Intra-arterial embolization for obstetric hemorrhage leads to good outcomes and few complications and it preserves fertility. Copyright © 2011 SERAM. Published by Elsevier Espana.

    2014-01-01

    Purpose. To identify and study causes of vitreous hemorrhage (VH) in pediatric age group and to investigate factors predicting visual and anatomical outcomes. Procedure. A retrospective review of patients aged 16 years or less with the diagnosis of vitreous hemorrhage from January 2005 until December 2010. Results. A total number of 230 patients (240 eyes) were identified. Traumatic vitreous hemorrhage accounted for 82.5%. In cases of accidental trauma, final visual acuity of 20/200 was significantly associated with visual acuity of ≥20/200 at presentation and the absence of retinal detachment at last follow-up. Patients with nontraumatic vitreous hemorrhage were significantly younger with higher rates of enucleation/evisceration/exenteration and retinal detachment at last follow-up compared to traumatic cases. Conclusion. Trauma is the most common cause of VH in pediatric age group. In this group, initial visual acuity was the most important predictor for visual outcome, and the presence of retinal detachment is a negative predictor for final good visual outcome. The outcome is significantly worse in nontraumatic cases compared to traumatic cases. PMID:25505975

    Background: Postpartum hemorrhage is the leading cause of severe maternal morbidity and death. A prompt management of uterine artery embolization (UAE) is important for a good outcome. UAE is generally accepted to be a safe and reliable procedure. Objective: To estimate critical patient characteristics influencing the success of UAE for the treatment of emergent primary postpartum hemorrhage. Materials and Methods: This was a cross sectional study that reviewed 121 patients who were diagnosed primary postpartum hemorrhage between February 2002 and December 2009 at a tertiary treatment center among 4,022 deliveries. We evaluated patient clinical characteristics associated with a successful surgical outcome of UAE. Results: The success rate for UAE was 96%. For two cases, UAE complication was associated with fever (>38.5oC). Five patients had problems that required admission to the intensive care unit (ICU). Conclusion: To increase the surgical success rate and lower the number of ICU admissions, the decision to treat primary postpartum hemorrhage using UAE should be based on individual patient clinical findings under the direction of obstetrics staff and an interventional radiologist.

    Platelets play an important role in the development of acute coronary syndromes. Evidence indicates that platelet-inhibiting drugs, such as glycoprotein IIb/IIIa inhibitors, can be beneficial when they are administered at the time of primary percutaneous coronary intervention for acute ST-segment-elevation myocardial infarction. However, an associated increase in the risk of bleeding is well documented. Diffuse alveolar hemorrhage is a rare but life-threatening and underdiagnosed complication of therapy with glycoprotein IIb/IIIa inhibitors. Diffuse alveolar hemorrhage can easily be mistaken for acute pulmonary edema, a condition commonly seen in patients with acute coronary syndrome. Physicians need to be aware of this diagnostic dilemma, because early treatment increases the chance that the patients will survive. Herein, we report the fatal outcome of diffuse alveolar hemorrhage in a 73-year-old man who presented with acute ST-segment-elevation myocardial infarction and was treated with tirofiban in conjunction with primary percutaneous coronary intervention. In addition, we review the medical literature pertaining to the sequelae of glycoprotein IIb/IIIa inhibitor therapy in the presence of diffuse alveolar hemorrhage. PMID:22412240

    Hemorrhage after pancreatoduodenectomy is a severe, life-threatening complication. This study was conducted to determine the guidelines appropriate for the prevention and management of hemorrhagic complications. We reviewed the medical records of 456 patients who had undergone pancreatoduodenectomy at our hospital between 1991 and 2000. Significant postoperative bleeding occurred in 21 patients (4.6%). Early bleeding (within the 5th postoperative day) caused by improper intraoperative hemostasis occurred in 5 of these cases; 3 of whom were saved by prompt operation and one by conservative management. The other 16 cases consisted of late bleeding (after the 5th postoperative day), of which 12 patients (75%) experienced pancreatic leaks and 8 pseudoaneurysms of major arteries. "Sentinel bleeding" was evident in 8 cases. Angiographic embolization was performed in 8 cases, 7 of which were successful. Reoperation was tried in 7 cases with complete hemostasis being achieved in 2. As a result, 15 of 21 patients obtained complete hemostasis and the mortality rate from hemorrhage was 28.6% (6/21). Rapid decision-making is mandatory when bleeding stigmata such as pseudoaneurysm on CT and sentinel bleeding are noted. Prompt operation for early bleeding and angiographic embolization for late bleeding are recommended. In order to prevent hemorrhage after pancreatoduodenectomy, meticulously performed hemostasis and the avoidance of pancreatic anastomotic leaks are essential.

  7. Massive obstetric hemorrhage: Current approach to management.

    PubMed

    Guasch, E; Gilsanz, F

    2016-01-01

    Massive obstetric hemorrhage is a major cause of maternal mortality and morbidity worldwide. It is defined (among others) as the loss of>2,500ml of blood, and is associated to a need for admission to critical care and/or hysterectomy. The relative hemodilution and high cardiac output found in normal pregnancy allows substantial bleeding before a drop in hemoglobin and/or hematocrit can be identified. Some comorbidities associated with pregnancy can contribute to the occurrence of catastrophic bleeding with consumption coagulopathy, which makes the situation even worse. Optimization, preparation, rational use of resources and protocolization of actions are often useful to improve outcomes in patients with postpartum hemorrhage. Using massive obstetric hemorrhage protocols is useful for facilitating rapid transfusion if needed, and can also be cost-effective. If hypofibrinogenemia during the bleeding episode is identified, early fibrinogen administration can be very useful. Other coagulation factors in addition to fibrinogen may be necessary during postpartum hemorrhage replacement measures in order to effectively correct coagulopathy. A hysterectomy is recommended if the medical and surgical measures prove ineffective.

    To know the arbovirus causing hemorrhagic fever in patients at the Mexican Institute of Social Security. A follow-up study was made in patients with probable diagnosis of hemorrhagic dengue. Blood samples were taken to look for dengue fever, yellow fever and San Luis, Tonate and Mayaro encephalitis viruses. Frequencies and proportions of the interest variables were analyzed. 35 patients were studied. Isolation and PCR results of the 13 samples were negative in 12 of them and positive to denguevirus-3 in one of them. The determination of IgM was positive for dengue fever in 25 cases; 2 were positive to Mayaro virus and 8 were negative to what was looked for. Hemorrhages and thrombocytopenia were more frequent in patients infected with dengue and Mayaro viruses; jaundice and encephalopathy were more frequent in the latter, and renal dysfunction, in patients with a negative result. Evolution was satisfactory in all cases, except for one (Mayaro), which presented hemorrhages, thrombocytopenia, jaundice and encephalopathy that lead to death. The results show the risk of appearance and dissemination of several vector-born diseases in Mexico. Thus, they require intensive epidemiological surveillance to identify them and to know their real occurrence and specific clinical profile.

    The plaintiff alleged that failure of the attending physician to manage her husband's hypertension properly resulted in his death from intracerebral hemorrhage. Four lines of evidence supported the defendant: (1) In 1970 to 1971 there was uncertainty in the medical community whether mild hypertension should be treated with drugs; this uncertainty still existed at the time of the trial. (2) Severe hypertension and advanced age are the two most important predisposing factors leading to intracerebral hemorrhage; the deceased patient had neither. (3) Hemorrhage into the cerebral cortex and underlying white matter is not typical of hypertensive intracerebral bleeding; more likely, rupture of an arteriovenous malformation occurred. (4) A diagnosis of hypertensive intracerebral hemorrhage is not one of exclusion but requires objective evidence of vascular change in the brain, heart and kidney; these changes were not found in the deceased patient. In conclusion, an expert witness should testify objectively rather than be the advocate of a lawyer's theory of liability. ImagesFig. 6.Fig. 7.Fig. 9.Fig. 10. PMID:7233893

    Individuals with eating disorders, including anorexia nervosa and bulimia nervosa, may present with a range of gastrointestinal (GI) manifestations. The oral cavity, salivary glands, GI tract, pancreas, and liver can be impacted by nutritional restrictive and binge/purging behaviors. Complications are often reversible with appropriate nutritional therapy. At times, however, the complications in these disorders may be severe, irreversible and even life threatening. Given the often covert nature of eating disorders, the practitioner must be attentive to subtle clues that may indicate their presence. Extensive diagnostic evaluations of the GI manifestations of eating disorders should be used only when nutritional rehabilitation does not remedy the problems.

    Gastrointestinal stromal tumors had the reputation for poor outcomes because of their lack of response to nonsurgical interventions. The discovery of gain-of-function mutations involving receptor tyrosine kinase growth factor receptors altered the biological understanding and management. Beginning in 2000, management of these tumors has changed dramatically because of the availability of tyrosine kinase inhibitors. The role of surgery continues to be refined. This article reviews how surgery and systemic therapy are being used, incorporating definitions of risk. Decisions on how to treat a patient is based on the risk of progression, pathologic characteristics, and tumor location. Copyright © 2016 Elsevier Inc. All rights reserved.

    PubMed

    Galant, S P

    1976-06-01

    The interplay between the gut and immune abnormality appears to be a logical extension of the thesis that secretory IgA is the major immunologic line of defense between the outside environment and the host. Thus immunologic deficiency, particularly of IgA and combined T- and B-lymphocyte abnormalites, profoundly influences gut integrity. Conversely, gut pathology is bound to interfere with immunologic function, so that both humoral and cellular immunity may be impaired. Finally, hypersensitivity phenomena in the gut, resulting in immune injury, may cause gastrointestinal disturbances. As better diagnostic tools have become available, more direct evidence of hypersensitivity immune injury has been described.

    Cancer stem cells (CSCs) are thought to be responsible for tumor initiation, drug and radiation resistance, invasive growth, metastasis, and tumor relapse, which are the main causes of cancer-related deaths. Gastrointestinal cancers are the most common malignancies and still the most frequent cause of cancer-related mortality worldwide. Because gastrointestinal CSCs are also thought to be resistant to conventional therapies, an effective and novel cancer treatment is imperative. The first reported CSCs in a gastrointestinal tumor were found in colorectal cancer in 2007. Subsequently, CSCs were reported in other gastrointestinal cancers, such as esophagus, stomach, liver, and pancreas. Specific phenotypes could be used to distinguish CSCs from non-CSCs. For example, gastrointestinal CSCs express unique surface markers, exist in a side-population fraction, show high aldehyde dehydrogenase-1 activity, form tumorspheres when cultured in non-adherent conditions, and demonstrate high tumorigenic potential in immunocompromised mice. The signal transduction pathways in gastrointestinal CSCs are similar to those involved in normal embryonic development. Moreover, CSCs are modified by the aberrant expression of several microRNAs. Thus, it is very difficult to target gastrointestinal CSCs. This review focuses on the current research on gastrointestinal CSCs and future strategies to abolish the gastrointestinal CSC phenotype. © 2016 The Authors.

  20. Management of Patients with Acute Lower Gastrointestinal Bleeding

    PubMed Central

    Strate, Lisa L.; Gralnek, Ian M.

    2016-01-01

    This guideline provides recommendations for the management of patients with acute overt lower gastrointestinal hemorrhage. Hemodynamic status should be initially assessed with intravascular volume resuscitation started as needed. Risk stratification based upon clinical parameters should be performed to help distinguish patients at high and low-risk of adverse outcomes. Hematochezia associated with hemodynamic instability may be indicative of an upper GI bleeding source and thus warrants an upper endoscopy. In the majority of patients, colonoscopy should be the initial diagnostic procedure and should be performed within 24 hours of patient presentation after adequate colon preparation. Endoscopic hemostasis therapy should be provided to patients with high risk endoscopic stigmata of bleeding including active bleeding, non-bleeding visible vessel, or adherent clot. The endoscopic hemostasis modality used (mechanical, thermal, injection or combination) is most often guided by the etiology of bleeding, access to the bleeding site, and endoscopist experience with the various hemostasis modalities. Repeat colonoscopy, with endoscopic hemostasis performed if indicated, should be considered for patients with evidence of recurrent bleeding. Radiographic interventions (tagged red blood cell scintigraphy, CT angiography, angiography) should be considered in high-risk patients with ongoing bleeding who do not respond adequately to resuscitation, and who are unlikely to tolerate bowel preparation and colonoscopy. Strategies to prevent recurrent bleeding should be considered. NSAID use should be avoided in patients with a history of acute lower GI bleeding particularly if secondary to diverticulosis or angioectasia. In patients with established cardiovascular disease who require aspirin (secondary prophylaxis), aspirin should not be discontinued. The exact timing depends on the severity of bleeding, perceived adequacy of hemostasis and the risk of a thromboembolic event. Surgery

  1. Unraveling the distinctive features of hemorrhagic and non-hemorrhagic snake venom metalloproteinases using molecular simulations

    Snake venom metalloproteinases are important toxins that play fundamental roles during envenomation. They share a structurally similar catalytic domain, but with diverse hemorrhagic capabilities. To understand the structural basis for this difference, we build and compare two dynamical models, one for the hemorrhagic atroxlysin-I from Bothrops atrox and the other for the non-hemorraghic leucurolysin-a from Bothrops leucurus. The analysis of the extended molecular dynamics simulations shows some changes in the local structure, flexibility and surface determinants that can contribute to explain the different hemorrhagic activity of the two enzymes. In agreement with previous results, the long Ω-loop (from residue 149 to 177) has a larger mobility in the hemorrhagic protein. In addition, we find some potentially-relevant differences at the base of the S1' pocket, what may be interesting for the structure-based design of new anti-venom agents. However, the sharpest differences in the computational models of atroxlysin-I and leucurolysin-a are observed in the surface electrostatic potential around the active site region, suggesting thus that the hemorrhagic versus non-hemorrhagic activity is probably determined by protein surface determinants.

    Ischemia has been considered to play a role in the development of acute pancreatitis. The aim of this study was to investigate the effect of ischemia, caused by hemorrhagic shock, on cerulein-induced acute pancreatitis in rats. Acute pancreatitis was induced by the intravenous infusion of a supramaximally stimulating dose of cerulein (10 micrograms/kg/hr) for 6 hr. Hemorrhagic shock was induced by the removal of blood until the mean arterial blood pressure reached 35 mm Hg. This level was maintained for 30 min, after which time all the blood was reinfused. Hemorrhagic shock alone induced no morphological change in the pancreas. However, after the induction of hemorrhagic shock in animals treated with cerulein, hemorrhage and parenchymal necrosis were frequently observed in the pancreas. Seven of 20 rats (35%) receiving cerulein plus hemorrhagic shock had died by 48 hr after the start of cerulein infusion, whereas none of the rats in the cerulein or shock group died during this experiment. Cathepsin B activity in the pancreas of the cerulein plus shock group was significantly higher than in the other groups at 48 hr. These results suggest that ischemia may be a contributing factor in the pathogenesis of acute pancreatitis.

  3. Risk and crisis management in intraoperative hemorrhage: Human factors in hemorrhagic critical events

    2011-01-01

    Hemorrhage is the major cause of cardiac arrest developing in the operating room. Many human factors including surgical procedures, transfusion practices, blood supply, and anesthetic management are involved in the process that leads to hemorrhage developing into a critical situation. It is desirable for hospital transfusion committees to prepare hospital regulations on 'actions to be taken to manage critical hemorrhage', and practice the implementation of these regulations by simulated drills. If intraoperative hemorrhage seems to be critical, a state of emergency should immediately be declared to the operating room staff, the blood transfusion service staff, and blood bank staff in order to organize a systematic approach to the ongoing problem and keep all responsible staff working outside the operating room informed of events developing in the operating room. To rapidly deal with critical hemorrhage, not only cooperation between anesthesiologists and surgeons but also linkage of operating rooms with blood transfusion services and a blood bank are important. When time is short, cross-matching tests are omitted, and ABO-identical red blood cells are used. When supplies of ABO-identical red blood cells are not available, ABO-compatible, non-identical red blood cells are used. Because a systematic, not individual, approach is required to prevent and manage critical hemorrhage, whether a hospital can establish a procedure to deal with it or not depends on the overall capability of critical and crisis management of the hospital.

    Snake venom metalloproteinases are important toxins that play fundamental roles during envenomation. They share a structurally similar catalytic domain, but with diverse hemorrhagic capabilities. To understand the structural basis for this difference, we build and compare two dynamical models, one for the hemorrhagic atroxlysin-I from Bothrops atrox and the other for the non-hemorraghic leucurolysin-a from Bothrops leucurus. The analysis of the extended molecular dynamics simulations shows some changes in the local structure, flexibility and surface determinants that can contribute to explain the different hemorrhagic activity of the two enzymes. In agreement with previous results, the long Ω-loop (from residue 149 to 177) has a larger mobility in the hemorrhagic protein. In addition, we find some potentially-relevant differences at the base of the S1' pocket, what may be interesting for the structure-based design of new anti-venom agents. However, the sharpest differences in the computational models of atroxlysin-I and leucurolysin-a are observed in the surface electrostatic potential around the active site region, suggesting thus that the hemorrhagic versus non-hemorrhagic activity is probably determined by protein surface determinants.

    Symptomatic intracerebral hemorrhage (sICH) is one of the most feared complications after administration of intravenous recombinant tissue plasminogen activator (IV rtPA). The aim of this study was to determine correlations between hemorrhage volume (HV) after IV rtPA treatment and risk factors for sICH. We analyzed 318 patients from the stroke registries of 4 hospitals in Korea. We confirmed hemorrhage by computed tomography (CT) or magnetic resonance imaging within 36 hours. Patient groups were classified by HV (0, 0-10, 10-25, and greater than 25 mL). Based on the HV, we evaluated the following: (1) predictors for hemorrhage; (2) rates of sICH according to various sICH definitions; and (3) 3-month functional outcomes after IV rtPA treatment. Among the 318 patients, hemorrhage occurred in 72 patients. HV was significantly correlated with atrial fibrillation (OR = 3.38, 95% CI = 1.87-6.09), early CT changes (OR = 3.17, 95% CI = 1.69-5.93), and dense artery sign (OR = 1.90, 95% CI = 1.07-3.39). Compared with the groups with HV less than 25 mL, patients with an HV of greater than 25 mL were more likely to have higher mortality rates (33.3% versus 11.8%) and worse outcomes at 3 months (good: 8.3% versus 50.3%; excellent: 0% versus 33.7%). HV after IV rtPA is an important predictor of clinical outcomes. Atrial fibrillation, early CT changes, and dense artery sign were significantly associated with large HVs; therefore, these patient factors might be considered before and after thrombolytic treatment.

    Objective to evaluate evidence of placental hemorrhage (PH) obtained through maternal interviews, patient charts, and placental pathology examinations as potential indicators of a “bleeding pathway” to preterm delivery (PTD). Design Prospective cohort Setting Fifty-two clinics in five communities in Michigan, USA (1998–2004) Population A subset (N=996) of cohort participants with complete placental pathology data Methods First trimester bleeding and placental abruption were ascertained by mid-trimester interviews and chart review, respectively. Disc-impacting blood clot was defined as a gross placental examination finding of a blood clot impacting adjacent tissue. Microscopic hemorrhage was defined as “high” (top quintile) scores on an aggregate measure of placental pathology findings suggestive of atypical maternal vessel hemorrhage. These four PH indicators were compared with one another and with risk of PTD assessed by logistic regression analyses. Main Outcome Measures PTD and PTD subtypes (i.e., <35 weeks, 35–36 weeks; spontaneous, medically indicated) compared with term deliveries. Results Placental abruption cases had 2.3 to 5.5-fold increased odds of the other 3 PH indicators. Disc-impacting blood clots and microscopic hemorrhage were associated with one another (OR=4.6), but not with first trimester bleeding. In a multivariable model that included all four PH indicators and confounders, risk of PTD <35 weeks was elevated with first trimester bleeding (OR=1.9 (1.0, 3.4)), placental abruption (OR=5.2 (1.7, 16.2)), disc-impacting blood clots (OR=2.3 (1.0, 5.0)); and microscopic hemorrhage (OR=2.4 (1.4, 4.2)). Conclusions Multiple clinical and subclinical PH indicators are associated with PTD, particularly early PTD. PMID:20074262

    Abstract Current guidelines recommend a period of moderate therapeutic hypothermia (TH) for comatose patients after cardiac arrest to improve clinical outcomes. However, in-vitro studies have reported platelet dysfunction, thrombocytopenia, and coagulopathy, results that might discourage clinicians from applying TH in clinical practice. We aimed to quantify the risks of hemorrhage observed in clinical studies. Medline and Embase were searched from inception to October 2015. Randomized controlled trials (RCTs) comparing patients undergoing TH with controls were selected, irrespective of the indications for TH. There were no restrictions for language, population, or publication year. Data on study characteristics, which included patients, details of intervention, and outcome measures, were extracted. Forty-three trials that included 7528 patients were identified from 2692 potentially relevant references. Any hemorrhage was designated as the primary outcome and was reported in 28 studies. The pooled results showed no significant increase in hemorrhage risk associated with TH (risk difference [RD] 0.005; 95% confidence interval [CI] −0.001–0.011; I2, 0%). Among secondary outcomes, patients undergoing TH were found to have increased risk of thrombocytopenia (RD 0.109; 95% CI 0.038–0.179; I2 57.3%) and transfusion requirements (RD 0.021; 95% CI 0.003–0.040; I2 0%). The meta-regression analysis indicated that prolonged duration of cooling may be associated with increased risk of hemorrhage. TH was not associated with increased risk of hemorrhage despite the increased risk of thrombocytopenia and transfusion requirements. Clinicians should cautiously assess each patient's risk-benefit profile before applying TH. PMID:26632746

  8. Effects of hemorrhage on cytokine gene transcription.

    Injury and blood loss are often followed by infection and the rapid development of organ system dysfunction, frequently involving mucosal sites, such as the lung and intestine. To examine possible mechanisms contributing to these conditions, we used semiquantitative polymerase chain reactions to determine cytokine mRNA expression among cellular populations isolated from mucosal and systemic anatomic sites of mice at predetermined time points following 30% blood volume hemorrhage with resuscitation 1 hr later. Within 1 hr after hemorrhage, significant increases were observed in mRNA levels for IL-1 alpha, IL-1 beta, IL-5, and TGF-beta in intraparenchymal pulmonary mononuclear cells. The levels of TGF-beta transcripts among alveolar macrophages were increased 1 hr following blood loss, and increase in IL-1 alpha transcripts was found starting 2 hr posthemorrhage. Cells from Peyer's patches showed significant increases in mRNA levels for IL-1 beta, IL-2, IL-5, IL-6, IFN-gamma, and TGF-beta during the 4 hr following hemorrhage. Significant increases in mRNA levels for IL-1 beta, TNF-alpha, and TGF-beta were present within 4 hr of blood loss among cells isolated from mesenteric lymph nodes. The expression of mRNA for most cytokines was not significantly altered in splenocytes or peripheral blood mononuclear cells at any time point following hemorrhage. These experiments demonstrate that blood loss, even if resuscitated, produces significant increases in proinflammatory and immunoregulatory cytokine gene transcription as early as 1 hr following hemorrhage. These posthemorrhage alterations in cytokine mRNA expression were particularly prominent at mucosal sites, suggesting a mechanism for the increased incidence of pulmonary and intestinal involvement in organ system failure following severe blood loss and injury.

    Spontaneous retroperitoneal hemorrhage is a rare clinical entity; signs and symptoms include pain, hematuria, and shock. Spontaneous retroperitoneal hemorrhage can be caused by tumors, such as renal cell carcinoma and angiomyolipoma; polyarteritis nodosa; and nephritis. The least common cause is segmental arterial mediolysis. Although computed tomography is used for the diagnosis of spontaneous retroperitoneal hemorrhage, it can miss segmental arterial mediolysis as the cause of the hemorrhage. The diagnosis of segmental arterial mediolysis as a cause of spontaneous retroperitoneal hemorrhage requires angiography, with pathologic confirmation for a definitive diagnosis.

    To assess the possible relationship between exogenous surfactant therapy and pulmonary hemorrhage in premature infants, we compared autopsy findings in 15 infants treated with exogenous surfactant and in 29 who died before the introduction of surfactant therapy. Infants who met the following criteria were included: birth weight 501 to 1500 gm, survival 4 hours to 7 days, and no congenital anomalies. Average birth weight, gestational age, and age at death were equivalent for the two groups. High rates of pulmonary hemorrhage were present in both groups (treated 80% vs untreated 83%). The untreated group had higher incidences of interstitial hemorrhage and lung hematomas and significantly more large interstitial hemorrhages: 31% untreated versus 0% treated (p < 0.05). The overall rate of intraalveolar hemorrhage was similar in the two groups, but surfactant-treated infants were more likely to have extensive intraalveolar hemorrhage: 53% versus 14% (p < 0.05). Most surfactant-treated infants who survived more than 24 hours had extensive intraalveolar hemorrhage (8/9). Patients who had extensive intraalveolar hemorrhage, with or without prior surfactant therapy, frequently had clinically significant pulmonary hemorrhage (7/12). These findings indicate that infants who die after surfactant therapy have higher rates of a specific type of pulmonary hemorrhage--extensive intraalveolar hemorrhage.

    Gastrointestinal absorption of citrate was measured in stone patients with idiopathic hypocitraturia to determine if citrate malabsorption could account for low urinary citrate. Citrate absorption was measured directly from recovery of orally administered potassium citrate (40 mEq.) in the intestinal lavage fluid, using an intestinal washout technique. In 7 stone patients citrate absorption, serum citrate levels, peak citrate concentration in serum and area under the curve were not significantly different from those of 7 normal subjects. Citrate absorption was rapid and efficient in both groups, with 96 to 98% absorbed within 3 hours. The absorption of citrate was less efficient from a tablet preparation of potassium citrate than from a liquid preparation, probably due to a delayed release of citrate from wax matrix. However, citrate absorption from solid potassium citrate was still high at 91%, compared to 98% for a liquid preparation. Thus, hypocitraturia is unlikely to be due to an impaired gastrointestinal absorption of citrate in stone patients without overt bowel disease.

    Ghrelin, as a kind of multifunctional protein polypeptide, is mainly produced in the fundus of the stomach and can promote occurrence and development of many tumors, including gastrointestinal tumors, which has been proved by the relevant researches. Most gastrointestinal stromal tumors (GISTs, about 80%), as the most common mesenchymal tumor, also develop in the fundus. Scientific research has confirmed that ghrelin, its receptors and mRNA respectively can be found in GISTs, which demonstrated the existence of a ghrelin autocrine/paracrine loop in GIST tissues. However, no reports to date have specified the mechanism whether ghrelin can promote the occurrence and development of GISTs. Studies of pulmonary artery endothelial cells in a low-oxygen environment and cardiac muscle cells in an ischemic environment have shown that ghrelin can activate the phosphatidylinositol 3-kinase/AKT/mammalian target of rapamycin (PI3K/AKT/mTOR) signaling pathway. Moreover, some studies of GISTs have confirmed that activation of the PI3K/AKT/mTOR pathway can indeed promote the growth and progression of GISTs. Whether ghrelin is involved in the development or progression of GISTs through certain pathways remains unknown. Can we find a new target for the treatment of GISTs? This review explores and summaries the relationship among ghrelin, the PI3K/AKT/mTOR pathway and the development of GISTs. PMID:28348480

    A retrospective study of cases of a unique intramural inflammatory mass within the feline gastrointestinal tract was performed in order to describe and characterize the lesion. Twenty-five cases were identified from archival surgical and postmortem tissues. The lesion most often occurred as an ulcerated intramural mass at the pyloric sphincter (n = 12) or the ileocecocolic junction or colon (n = 9); the remaining cases were in the small intestine. Seven cases also had lymph node involvement. The lesions were characterized by eosinophilic inflammation, large reactive fibroblasts, and trabeculae of dense collagen. Intralesional bacteria were identified in 56% of the cases overall and all of the ileocecocolic junction and colon lesions. Fifty-eight percent of cats tested had peripheral eosinophilia. Cats treated with prednisone had a significantly longer survival time than those receiving other treatments. We propose that this is a unique fibroblastic response of the feline gastrointestinal tract to eosinophilic inflammation that in some cases is associated with bacteria. The lesion is often grossly and sometimes histologically mistaken for neoplasia.

    Systemic vasculitis is often not considered as a possible diagnosis by clinicians because of its low prevalence compared with other more common diseases. Vasculitis can affect any end organ, and it is therefore often missed early on in disease progression. Gastrointestinal (GI) manifestations of vasculitis are considered rare and the presentation is often nonspecific. However, if there is significant involvement of the major vessels of the gastrointestinal system, life-threatening sequelae, including perforation and bowel ischemia, may occur. This makes early and immediate management crucial to improve long-term morbidity and mortality. Diagnosis of various GI vasculitides often relies on correlation of clinical manifestations with pathology and additional investigations. This paper reviews the various vasculitides that affect the GI tract, including systemic lupus erythematosus, mixed connective tissue disease, Henoch Schönlein purpura, polyarteritis nodosa, Churg-Strauss syndrome, Wegener's granulomatosis, microscopic polyangiitis, enterocolic lymphocytic phlebitis, and Behcet's disease. Segmental arterial mediolysis, mistakenly believed to be a vasculitis, is also discussed.

  17. Electrolyte Balance in Gastrointestinal Disease

    Even small losses of gastrointestinal secretions when combined with reduced intake of electrolytes may seriously disturb electrolyte balance. Knowledge of the ionic composition of secretions lost is essential in planning therapy. Loss of gastric contents usually results in excessive loss of chloride; in achlorhydria this is not the case. Loss of sodium and potassium may be large in either case and is often underestimated. Small bowel obstruction results in a more balanced loss of electrolyte which may not affect acidbase balance greatly. In diarrhea loss of base predominates, and may result in a large potassium deficit. Steatorrhea due to nontropical sprue results in large fecal losses of sodium, potassium and chloride, in addition to the large calcium and phosphorus loss. In chronic peptic ulcer excessive ingestion of milk and absorbable alkalies may result in hypercalcemia, azotemia and alkalosis, without hypercalciuria. Since renal function is usually adequate in the milder gastrointestinal disturbances, electrolyte and fluid replacement should be started early, and can be guided by generally available laboratory tests, the carbon dioxide combining power and serum chloride levels, provided the predominate ionic loss is known and potassium deficiency remedied. If this is done, development of serious fluid and electrolyte deficits can usually be prevented. PMID:13260927

    This article discusses the most interesting presentations at Digestive Disease Week, held in San Diego, in the field of functional and motor gastrointestinal disorders. One of the most important contributions was undoubtedly the presentation of the new Rome IV diagnostic criteria for functional gastrointestinal disorders. We therefore devote some space in this article to explaining these new criteria in the most common functional disorders. In fact, there has already been discussion of data comparing Rome IV and Rome III criteria in the diagnosis of irritable bowel syndrome, confirming that the new criteria are somewhat more restrictive. From the physiopathological point of view, several studies have shown that the aggregation of physiopathological alterations increases symptom severity in distinct functional disorders. From the therapeutic point of view, more data were presented on the efficacy of acotiamide and its mechanisms of action in functional dyspepsia, the safety and efficacy of domperidone in patients with gastroparesis, and the efficacy of linaclotide both in irritable bowel syndrome and constipation. In irritable bowel syndrome, more data have come to light on the favourable results of a low FODMAP diet, with emphasis on its role in modifying the microbiota. Finally, long-term efficacy data were presented on the distinct treatment options in achalasia.

    Cerebral amyloid angiopathy (CAA) usually manifests as cerebral hemorrhage, especially as nontraumatic hemorrhages in normotensive elderly patients. Other manifestations are subarachnoid (SAH), subdural, intraventricular hemorrhage (IVH) and superficial hemosiderosis. A 52-year-old hypertensive woman presented with recurrent neurological deficits over a period of 2 years. Her serial brain magnetic resonance imaging and computed tomography scans showed recurrent SAH hemorrhage, and also intracerebral, IVH and spinal hemorrhage, with superficial siderosis. Cerebral angiograms were normal. Right frontal lobe biopsy showed features of CAA. CAA can present with unexplained recurrent SAH hemorrhage, and may be the initial and prominent finding in the course of disease in addition to superficial cortical siderosis and intracerebal and spinal hemorrhages.

    Endoscopy is extremely useful for the diagnosis of upper gastrointestinal bleeding. At the present time, therapeutic measures are been used during the endoscopy to stop bleeding. This paper reports the experience of hospital de Talca in the endoscopic treatment of upper gastrointestinal bleeding. Thirty four patients (22 male) with bleeding not originating from esophageal or gastric varices were treated with direct absolute alcohol injection into the bleeding lesions. The procedure was successful in 31 patients. Three of the 34 patients required surgery, but only one of those successfully sclerosed (97% success). There were no complications attributable to the procedure. It is concluded that this therapeutic modality must be implemented in places were gastrointestinal endoscopy is performed.

    A Holstein cow was intubated with 182 mg of 97% pure T-2 toxin (0.44 mg/kg of body weight) for 15 days. A dairy ration containing 50 mg/kg (50 ppm) of T-2 toxin was refused. A calf, born four days after onset of maternal treatment, was intubated with 26.2 mg of purified T-2 toxin (0.6 mg/kg of body weight) for seven consecutive days and then on alternate days for a total of 16 days. The calf was severely affected clinically by the T-2 toxin. The T-2 toxin failed to cause bovine hemorrhagic syndrome in either animal. Unspecific gastrointestinal lesions were noted in the cow but none were detected in the calf. In the calf, severe depression, hindquarter ataxia, knuckling of the rear feet, listlessness and anorexia were caused by the T-2 toxin. PMID:7427850

    The American Association for the Study of Liver Diseases (AASLD) guidelines recommend that antibiotic prophylaxis should be instituted in any patient with cirrhosis and gastrointestinal hemorrhage, and that oral norfloxacin, intravenous ciprofloxacin, and ceftriaxone are preferable. However, the antimicrobial spectrum of the first generation of cephalosporins (cefazolin) covers a wide range of bacteria species, including community-acquired strains of Escherichia coli and Klebsiella pneumoniae, but their efficacy as prophylactic antibiotics in cirrhotic patients with acute hemorrhage was seldom warranted in the literature. This study aimed to explore the effects of cefazolin on the outcome of cirrhotic patients with acute variceal hemorrhage after endoscopic interventions. A cross-sectional, retrospective chart review study was conducted on cirrhotic patients with acute variceal hemorrhage who underwent endoscopic procedures in a medical center. Cirrhotic patients who did not receive antibiotics were classified as group A (n = 63) while patients who received intravenous cefazolin 1 g q8 h for 2-7 days were classified as group B (n = 50). The end points were the prevention of infection, length of hospital stay, time of rebleeding, and death. A total of 113 patients were studied (male/female: 82/31; age: 56.8 ± 13.5 years). The incidence of infection (including proven infections) and bacteremia were significantly lower in group B patients (38.1% vs. 16.0%, P = 0.010; 17.5% vs. 4.0%, P = 0.026; 9.5% vs. 0%, P = 0.033, respectively). The no prophylactic antibiotics treatment was the independent risk factor. There was no significant difference between the two groups with respect to the source of bleeding, type of endoscopic intervention, length of hospital stay, and mortality. Actuarial probability of remaining free of early rebleeding (<7 days) was P = 0.105 by log-rank test for all cirrhosis patients and P = 0.085 for Child-Pugh class A patients

    This study describes educational placement of school-aged children after spontaneous intracerebral hemorrhage and examines whether educational placement is associated with severity of neurological deficits. Children with spontaneous intracerebral hemorrhage presenting from 2007 to 2013 were prospectively enrolled at three tertiary children's hospitals. The Pediatric Stroke Outcome Measure and parental interview gathered information about neurological outcome, school attendance, and educational placement. The cohort of 92 enrolled children included 42 school-aged children (6 to 17 years) with intracerebral hemorrhage. Four children died; one was excluded because of preexisting cognitive deficits. Thirty-seven children completed three-month follow-up, and 30 completed 12-month follow-up. At 12 months, 14 children (46.7%) received regular age-appropriate programming, 12 (40%) attended school with in-class services, three (10%) were in special education programs, and one child (3.3%) received home-based services because of intracerebral hemorrhage-related deficits. Of 30 children with three- and 12-month follow-up, 14 (46.7%) improved their education status, 13 (43.3%) remained at the same education level, and three (10%) began to receive in-class services. An increasing Pediatric Stroke Outcome Measure score predicted the need for educational modifications at three months (odds ratio, 3.3; 95% confidence interval, 1.4 to 7.9; P = 0.007) and at 12 months (odds ratio, 2.1; 95% confidence interval, 1.1 to 3.9; P = 0.025). Most children returned to school within a year after intracerebral hemorrhage, and many had a reduction in the intensity of educational support. However, a great need for educational services persisted at 12 months after intracerebral hemorrhage with fewer than half enrolled in regular age-appropriate classes. Worse deficits on the Pediatric Stroke Outcome Measure were associated with remedial educational placement. Copyright © 2016 Elsevier

Through the conceptual innovations in metagenomics and the improvements in DNA high-throughput sequencing and bioinformatics analysis technology, gastrointestinal microbiology has entered the metagenomics era and become a hot topic worldwide. Human microbiome research is underway, however, most studies in this area have focused on the composition and function of the intestinal microbiota and the relationship between intestinal microbiota and metabolic diseases (obesity, diabetes, metabolic syndrome, etc.) and intestinal disorders [inflammatory bowel disease, colorectal cancer, irritable bowel syndrome (IBS), etc.]. Few investigations on microbiota have been conducted within the upper gastrointestinal tract (esophagus, stomach and duodenum). The upper gastrointestinal microbiota is essential for several gastrointestinal illnesses, including esophagitis, Barrett’s esophagus, and esophageal carcinoma, gastritis and gastric cancer, small intestinal bacterial overgrowth, IBS and celiac disease. However, the constitution and diversity of the microbiota in different sections of the upper gastrointestinal tract under health and various disease states, as well as the function of microbiota in the pathogenesis of various digestive diseases are still undefined. The current article provides an overview of the recent findings regarding the relationship between upper gastrointestinal microbiota and gastrointestinal diseases; and discusses the study limitations and future directions of upper gastrointestinal microbiota research.

    2017-01-01

    Periprocedural management of antithrombotics for gastrointestinal endoscopy is a common clinical issue, given the widespread use of these drugs for primary and secondary cardiovascular prevention. For diagnostic procedures, with or without biopsy, no adjustments in antithrombotics are usually needed. For operative procedures, balancing the risk of periprocedural hemorrhage with the continuation of antithrombotics against the chance of recurrent thromboembolic events with their discontinuation may be challenging. Oral anticoagulants need to be temporarily withheld, and consideration must be given to whether a periendoscopic “bridge” therapy, typically a low-molecular-weight heparin, should be used in order to minimize the risk of thromboembolic events. Although some emerging evidence has shown that patients receiving heparin bridging appear to be at increased risk of overall and major bleeding and at similar risk of thromboembolic events compared to controls, bridging therapy is still recommended for patients on vitamin K antagonists who are at high thrombotic risk. Conversely, bridging therapy is usually not needed for patients taking new oral agents, which are characterized by shorter half-lives, and a rapid offset and onset of action. Management of antiplatelet therapy requires special care in patients on secondary prevention, especially those with coronary stents. This review is intended to summarize the recommendations of updated International Guidelines designed to help the decision-making process in such an intricate field. PMID:28042233

    A small but significant percentage of vascular tumors may develop at extracutaneous location. They are difficult to detect on the physical exam and usually they require immediate intervention. Pediatric surgeons must have acknowledge of its prognostic and therapeutic implications. We report 4 of these patients. Patient 1 was a healthy newborn who presented in the second week of life, recurrent severe gastrointestinal bleeding, thrombocytopenia and anemia. Diagnosis of multifocal linfangioendoteliomatosis with thrombocytopenia was established. Patient 2 had prenatal diagnosis of ascites and presented at birth sepsis, anemia, thrombocytopenia and hypoproteinemia. Upon laparotomy hemorrhagic ascites and thickening of rectum-sigmoid wall and mesentery were found. Pathologic diagnosis was Kaposiform hemangioendothelioma and the clinical course was consistent with Kassabach-Merrit phenomenon. Patient 3 had at birth, multifocal hepatic GLUT1- hemangiomatosis with severe cardiac insufficiency and coagulopathy. She died while waiting for a liver transplantation. Patient 4 is a girl who presented in the newborn period with vomiting and hematochezia. She required several transfusions and endoscopic biopsies showed a vascular tumor that infiltrated duodenum, jejunum and mesentery. Imaging studies and histologic findings on biopsy led to the diagnostic of juvenile hemangioma GLUT-1+. Vascular tumors of the digestive tract may be difficult to diagnosis and their classification is still incomplete. Pediatric surgeons must be acquainted with these varieties of tumors because they are always involved in diagnosis and therapeutic decision making.

    Diverticulosis is the most frequent cause of lower gastrointestinal (GI) bleeding in adults in western countries. The aims of the present study were to analyze: 1) the diagnostic and therapeutic management of patients with severe lower GI bleeding due to diverticulosis; 2) associated morbidity and mortality; 3) the need for surgery, and 4) bleeding recurrence rates after hospital discharge. Were retrospectively reviewed 42 patients with severe lower GI bleeding due to diverticulosis. Patients with rectorrhagia requiring transfusion of at least three packed red blood cell units and those with a decrease in hematocrit of 10 points or more were included. As a control group, we used 133 patients with severe lower GI hemorrhage due to causes other than colonic diverticular disease. All patients were stabilized with conservative measures except one who required emergency surgery. Colonoscopy was performed in 39 patients and the most frequent finding consisted of recent signs of bleeding independently of whether colonoscopy was performed early or was delayed. Endoscopic treatment with Argon laser electrocoagulation was performed in one patient. Bleeding recurrence after hospital discharge occurred in 13 patients (31%); of these, seven (16%) required hospital readmission. Severe lower GI bleeding due to diverticulosis can usually be resolved with conservative treatment although the percentage of bleeding recurrence is high. Early endoscopy is not as important as in the remaining causes of severe lower GI bleeding.

    ABSTRACT In an autoimmune disease, the immune system attacks and harms the body's own tissues. The systemic autoimmune diseases include collagen vascular diseases, the systemic vasculitides, Wegener granulomatosis, and Churg-Strauss syndrome. These disorders can involve any part of the gastrointestinal tract, hepatobiliary system and pancreas. They can cause a variety of gastrointestinal manifestations that are influenced by the pathophysiologic characteristics of the underlying disease process. There is a wide variation of gastrointestinal manifestations from these autoimmune disorders including, but not limited to: oral ulcers, dysphagia, gastroesophageal reflux disease, abdominal pain, constipation, diarrhea, fecal incontinence, pseudo-obstruction, perforation and gastrointestinal bleeding. Clinical workup should be initiated by the patient's subjective complaints. In this review, we analyze the effects of autoimmune diseases on the gastrointestinal tract. PMID:21977190

    For more than 50 years bleeding from gastrointestinal angiodysplasias has been treated by hormonal therapy with estrogens and progesterons. After a randomized study finally demonstrated that hormones have no effect on bleeding events and transfusion requirements, therapy has switched to endoscopic coagulation. However, angiodysplasias tend to recur over months to years and endoscopy often has to be repeated for long time periods. Thalidomide, which caused severe deformities in newborn children in the 1960s, is now increasingly used after it was shown to suppress tumor necrosis factor alpha, inhibit angiogenesis and to be also effective for treatment of multiple myeloma. In 2011 thalidomide was proven to be highly effective for treatment of bleeding from gastrointestinal angiodysplasias in a randomized study. Further evidence by uncontrolled studies exists that thalidomide is also useful for treatment of bleeding in hereditary hemorrhagic telangiectasia. In spite of this data, endoscopic therapy remains the treatment of choice in many hospitals, as thalidomide is still notorious for its teratogenicity. However, patients with gastrointestinal bleeding related to angiodysplasias are generally at an age in which women have no child-bearing potential. Teratogenicity is therefore no issue for these elderly patients. Other side-effects of thalidomide like neurotoxicity may limit treatment options but can be monitored safely.

    Gastrointestinal (GI) fistulas are frequently very serious complications that are associated with high morbidity and mortality. GI fistulas can cause a wide array of pathophysiological effects by allowing abnormal diversion of the GI contents, including digestive fluid, water, electrolytes, and nutrients, from either one intestine to another or from the intestine to the skin. As an alternative to surgery, recent technical advances in interventional radiology and percutaneous techniques have been shown as advantageous to lower the morbidity and mortality rate, and allow for superior accessibility to the fistulous tracts via the use of fistulography. In addition, new interventional management techniques continue to emerge. We describe the clinical and imaging features of GI fistulas and outline the interventional management of GI fistulas.

    2014-01-01

    Microbial species participate in the genesis of a substantial number of malignancies—in conservative estimates, at least 15% of all cancer cases are attributable to infectious agents. Little is known about the contribution of the gastrointestinal (GI) microbiome to the development of malignancies. Resident microbes can promote carcinogenesis by inducing inflammation, increasing cell proliferation, altering stem cell dynamics, and producing metabolites such as butyrate, which affect DNA integrity and immune regulation. Studies in humans and rodent models of cancer have identified effector species and relationships among members of the microbial community in the stomach and colon that increase the risk for malignancy. Strategies to manipulate the microbiome, or the immune response to such bacteria, could be developed to prevent or treat certain GI cancers. PMID:24406471

  1. Mast cells in gastrointestinal disorders.

    PubMed

    2016-05-05

    Mast cells are constitutively found in the gastrointestinal (GI) tract. The three major physiological functions of GI mast cells comprise of - as far as we know - regulation of GI functions, namely epithelial and endothelial functions, crosstalk with the enteric nervous system, and contribution to the host defense against bacterial, viral and parasitic agents. A number of chronic GI diseases, including inflammatory bowel disease (Crohn's disease, ulcerative colitis), celiac disease, irritable bowel syndrome, and food allergies, are thought to be associated with mast cell hyperplasia and humoral activity. Clinical conditions characterized by a decrease in mast cell functionality are not known so far. In the present review, we summarize current evidence which show that human mast cells play a central role at the GI barrier, both in health and disease.

    Gastrointestinal lymphomas represent 5–20% of extranodal lymphomas and mainly occur in the stomach and small intestine. Clinical findings are not specific, thus often determining a delay in the diagnosis. Imaging features at conventional and cross-sectional imaging must be known by the radiologist since he/she plays a pivotal role in the diagnosis and disease assessment, thus assisting in the choice of the optimal treatment to patients. This review focuses on the wide variety of imaging presentation of esophageal, gastric, and small and large bowel lymphoma presenting their main imaging appearances at conventional and cross-sectional imaging, mainly focusing on computed tomography and magnetic resonance, helping in the choice of the best imaging technique for the disease characterization and assessment and the recognition of potential complications.

Various psychological, infectious and other stressors can disrupt this harmonious relationship and alter both the microbiome and visceral pain responses. There are critical sensitive periods that can impact visceral pain responses in adulthood. In this review we provide a brief background of the intestinal microbiome and emerging concepts of the bidirectional interactions between the microbiome, gut and brain.

    2007-01-01

    Despite substantial fluctuations in daily food intake, animals maintain a remarkably stable body weight, because overall caloric ingestion and expenditure are exquisitely matched over long periods of time, through the process of energy homeostasis. The brain receives hormonal, neural, and metabolic signals pertaining to body-energy status and, in response to these inputs, coordinates adaptive alterations of energy intake and expenditure. To regulate food consumption, the brain must modulate appetite, and the core of appetite regulation lies in the gut-brain axis. This Review summarizes current knowledge regarding the neuroendocrine regulation of food intake by the gastrointestinal system, focusing on gastric distention, intestinal and pancreatic satiation peptides, and the orexigenic gastric hormone ghrelin. We highlight mechanisms governing nutrient sensing and peptide secretion by enteroendocrine cells, including novel taste-like pathways. The increasingly nuanced understanding of the mechanisms mediating gut-peptide regulation and action provides promising targets for new strategies to combat obesity and diabetes. PMID:17200702

Researchers are still seeking biomarkers for irritable bowel syndrome and have presented new data. One study confirmed that the use of low-dose antidepressants has an antinociceptive effect without altering the psychological features of patients with functional dyspepsia. A contribution that could have immediate application is the use of transcutaneous electroacupuncture, which has demonstrated effectiveness in controlling nausea in patients with gastroparesis. New data have come to light on the importance of diet in irritable bowel syndrome, although the effectiveness of a low-FODMAP diet seems to be losing momentum with time. Multiple data were presented on the long-term efficacy of rifaximin therapy in patients with irritable bowel syndrome and diarrhoea. In addition, among other contributions, and more as a curiosity, a study evaluated the effect of histamine in the diet of patients with irritable bowel syndrome.

    Viral hemorrhagic fevers are diseases caused by viruses which belong to different families, many of them causing severe diseases. These viruses may produce different symptomatology together with a severe multisystem syndrome, and the final result might be the production of hemorrhages in several sites of the body. The majority of them have no other treatment than supportive therapy, although some antiviral drugs can be used in some circumstances. Transmission of VHF has been demonstrated through contact with animal vectors or person-to-person through the contact with body fluids. No risk of transmission has been found during the incubation period, but when the viral load is high the risk of transmission is greatest. Both health care and clinical laboratory workers must safely handle patients and specimens by taking all required precautions during their management. PMID:27014378

This requires effective identification and isolation of cases, timely contact tracing and monitoring, proper usage of barrier personal protection gear by health workers, and safely conducted burials. Solely implementing these measures is insufficient for infection control; control efforts must be culturally sensitive and conducted in a transparent manner to promote the necessary trust between the community and infection control team in order to succeed. This article provides a review of the literature on infection control during filoviral hemorrhagic fever outbreaks focusing on outbreaks in a developing setting and lessons learned from previous outbreaks.

    Tice and colleagues pioneered site-specific, sustained-release drug delivery to the brain almost 30 years ago. Currently there is one drug approved for use in this manner. Clinical trials in subarachnoid hemorrhage have led to approval of nimodipine for oral and intravenous use, but other drugs, such as clazosentan, hydroxymethylglutaryl CoA reductase inhibitors (statins) and magnesium, have not shown consistent clinical efficacy. We propose that intracranial delivery of drugs such as nimodipine, formulated in sustained-release preparations, are good candidates for improving outcome after subarachnoid hemorrhage because they can be administered to patients that are already undergoing surgery and who have a self-limited condition from which full recovery is possible.

    2009-12-01

    Trauma with resultant hypovolemic shock remains both prevalent and difficult to treat. Standard strategies using volume resuscitation and catecholamine support have historically yielded poor results. Vasopressin has emerged as a possible pharmacologic adjunct, particularly in patients with shock refractory to the administration of fluids and catecholamines. Much of the data regarding vasopressin is extrapolated from its usefulness in cases of nonhypovolemic human shock, which are supported by convincing animal studies. It is true that humans show a deficiency in vasopressin minutes after significant hemorrhage that can respond to administration of exogenous vasopressin. When given in physiological dosing regimens, vasopressin appears to be a safe adjunct to other therapy. Definite recommendations regarding indications for use, recommended dose, and long-term outcome in patients with hemorrhagic shock await a much needed prospective, randomized, controlled trial.

    Hemorrhagic stroke is a common and severe neurological disorder and is associated with high rates of mortality and morbidity, especially for intracerebral hemorrhage (ICH). Increasing evidence demonstrates that oxidative stress responses participate in the pathophysiological processes of secondary brain injury (SBI) following ICH. The mechanisms involved in interoperable systems include endoplasmic reticulum (ER) stress, neuronal apoptosis and necrosis, inflammation, and autophagy. In this review, we summarized some promising advances in the field of oxidative stress and ICH, including contained animal and human investigations. We also discussed the role of oxidative stress, systemic oxidative stress responses, and some research of potential therapeutic options aimed at reducing oxidative stress to protect the neuronal function after ICH, focusing on the challenges of translation between preclinical and clinical studies, and potential post-ICH antioxidative therapeutic approaches.

    2007-03-01

    Liver involvement in hereditary hemorrhagic telangiectasia (HHT) consists of extensive intrahepatic vascular malformations associated with blood shunting (arteriovenous, arterioportal and/or portovenous). It is a rare disorder that nevertheless can result in significant systemic and hepatobiliary abnormalities. Although hepatic vascular malformations are present in a majority of patients with HHT, symptoms occur in a only a minority with a clear predominance for the female gender. Symptoms from liver vascular malformations are often misdiagnosed and this can lead to potentially harmful interventions. In this review article, clinical findings of liver involvement in HHT and their pathophysiology are discussed as well as diagnostic methodologies, therapies used and their outcome. Data presented is based on a review of the literature performed in October 2006 using the following MEDLINE search terms: (hereditary hemorrhagic telangiectasia [ALL] OR Rendu-Osler-Weber [ALL]) AND (liver OR hepatic [ALL]). Papers were considered if they were published in English and if they included specific cases that were sufficiently described.

The mechanisms involved in interoperable systems include endoplasmic reticulum (ER) stress, neuronal apoptosis and necrosis, inflammation, and autophagy. In this review, we summarized some promising advances in the field of oxidative stress and ICH, including contained animal and human investigations. We also discussed the role of oxidative stress, systemic oxidative stress responses, and some research of potential therapeutic options aimed at reducing oxidative stress to protect the neuronal function after ICH, focusing on the challenges of translation between preclinical and clinical studies, and potential post-ICH antioxidative therapeutic approaches.

    Haemorrhage is a rare complication of meningiomas that can occur spontaneously, after embolization, stereotactic radiation and perioperatively. Our first case was a 16 year old male, admitted with spastic quadriparesis, and retention of urine. Magnetic Resonance Imaging (MRI) revealed anteriorly placed cervical intradural extramedullary mass. Patient underwent emergency surgery following sudden worsening of neurological symptoms and intratumoral bleed was noted peroperatively. Tumor was labeled as angiomatous meningioma with hemorrhage. The second case was of a 45 year female who presented with history of sudden onset weakness in right upper and lower limb followed by unconsciousness. MRI revealed heterogeneous lesion in left parasagittal area with intratumoral bleed. Left frontal craniotomy with tumour decompression was performed. Tumour was labelled as meningothelial meningioma with haemorrhage. Meningiomas with hemorrhagic onset remain rare, and pathophysiology is still incompletely understood. Prevention and outcome of intratumoral haemorrhage highly depends on early diagnosis and adequate treatment.

    An 18-year-old man, presented a lower vitreous hemorrhage of unknown cause. Multiple tests are performed, including Ophthalmic Ultrasound and Fluorescein Angioghaphy (FA), they did not find justification of bleeding. Finally, we decide to do a Biomocroscopía Ultrasonic (UBM) showing an iridociliary cyst. The iridociliary cysts are single or multiple, primary or secondary. The primaries are usually benign so, they do not require treatment. When the cyst has a considerable size, it may produce a focal plateau iris with or without angle-closure. Our case reveals an unusual complication that should take notice of when you have an unknown vitreous hemorrhage. Copyright © 2013 Sociedad Española de Oftalmología.

    Massive hemorrhagic ascites (4470 mL, range 1-10 L) in women with endometriosis is a rare condition occurring predominantly in black women. Of the 43 case reports published, 42 are compatible with the hypothesis that the hemorrhagic ascites is predominantly a consequence of excessive ovarian transudation similar to a Meigs syndrome. Indeed, bilateral ovariectomy cures the condition without recurrences, whereas after unilateral ovariectomy or cystectomy recurrence rate is more than 50%; during ovarian suppression by luteinizing hormone-releasing hormone agonist ascites disappears, but reappears after treatment. Superficial pelvic endometriosis also contributes to the ascites because after superficial endometriosis destruction the recurrence rate is only 4 in 14. Based on these data, it is suggested, to scrutinize the ovaries for tumors given the analogy with Meigs syndrome. In women desiring fertility, conservative treatment with destruction of endometriosis only can be attempted given the cure rate of some 20%. It is unknown what the effect of ovulation induction would be.

    Aneurysmal subarachnoid hemorrhage remains one of the more devastating forms of stroke due in large part to delayed cerebral ischemia that appears days to weeks following the initial hemorrhage. Therapies exclusively targeting large caliber arterial vasospasm have fallen short, and thus we asked whether capillary dysfunction contributes to delayed cerebral ischemia after subarachnoid hemorrhage. Using a mouse model of subarachnoid hemorrhage and two-photon microscopy we showed capillary dysfunction unrelated to upstream arterial constriction. Subarachnoid hemorrhage decreased RBC velocity by 30%, decreased capillary pulsatility by 50%, and increased length of non-perfusing capillaries by 15%. This was accompanied by severe brain hypoxia and neuronal loss. Hyaluronidase, an enzyme that alters capillary blood flow by removing the luminal glycocalyx, returned RBC velocity and pulsatility to normal. Hyaluronidase also reversed brain hypoxia and prevented neuron loss typically seen after subarachnoid hemorrhage. Thus, subarachnoid hemorrhage causes specific changes in capillary RBC flow independent of arterial spasm, and hyaluronidase treatment that normalizes capillary blood flow can prevent brain hypoxia and injury after subarachnoid hemorrhage. Prevention or treatment of capillary dysfunction after subarachnoid hemorrhage may reduce the incidence or severity of subarachnoid hemorrhage-induced delayed cerebral ischemia. PMID:26661183
