Intractable oesophageal variceal bleeding caused by splenic arteriovenous fistula: treatment by transcatheter arterial embolization. (1/106)We describe a rare case of splenic arteriovenous fistula and venous aneurysm which developed after splenectomy in a 40-year-old woman who presented with epigastralgia, watery diarrhoea, repeated haematemesis and melaena caused by hyperkinetic status of the portal system and bleeding of oesophageal varices. It was diagnosed by computed tomography and angiography, and obliterated with giant Gianturco steel coils. (+info)
Anthranoid laxative use is not a risk factor for colorectal neoplasia: results of a prospective case control study. (2/106)BACKGROUND: Anthranoid laxatives are the most commonly used purgatives in the therapy of acute and chronic constipation. Recent experimental data and a prospective cohort study provide evidence of a possible risk of anthranoid use for the development of colorectal neoplasms. MATERIALS AND METHODS: We performed a prospective case control study at the University of Erlangen to investigate the risk of anthranoid laxative use for the development of colorectal adenomas or carcinomas. A total of 202 patients with newly diagnosed colorectal carcinomas, 114 patients with adenomatous polyps, and 238 patients (controls) with no colorectal neoplasms who had been referred for total colonoscopy were studied. The use of anthranoid preparations was assessed by standardised interview, and endoscopically visible or microscopic melanosis coli was studied by histopathological examination. RESULTS: There was no statistically significant risk of anthranoid use for the development of colorectal adenomas (unadjusted odds ratio 1.0; 95% CI 0.5-1.9) or carcinomas (unadjusted odds ratio 1.0; 95% CI 0.6-1.8). Even after adjustment for the risk factors age, sex, and blood in the stools by logistic regression analysis the odds ratio for adenomas was 0.84 (95% CI 0. 4-1.7) and for carcinomas 0.93 (95% CI 0.5-1.7). Also, there were no differences between the patient and control groups for duration of intake. Macroscopic and high grade microscopic melanosis coli were not significant risk factors for the development of adenomas or carcinomas. CONCLUSION: Neither anthranoid laxative use, even in the long term, nor macroscopic or marked microscopic melanosis coli were associated with any significant risk for the development of colorectal adenoma or carcinoma.

Further studies of canine von Willebrand's disease. (3/106)Additional characterization of von Willebrand's disease (VWD) in a family of German shepherd dogs is presented. Genetic studies of three generations of affected dogs indicate that about 50% of the progeny are affected if one parent has VWD and about 60% if both parents have the defect. Some of these progeny manifested an incomplete form of VWD, suggesting autosomal dominant inheritance with variable expressivity. The disease become progressively less severe with advancing age and repeated pregnancies. Ristocetin-induced platelet aggregation was significantly reduced in VWD dogs as compared with normal, thrombopathic, and hemophilic carrier dogs. Immunodiffusion and electroimmunodiffusion studies with rabbit anticanine factor VII showed the level of factor VII-related antigen to be low in VWD dogs but present in increased amounts in hemophilic dogs. VWD affected dogs had markedly delayed hemostatic plug formation, but their plugs appeared normal by light and electron microscopy. Their platelet nucleotides, ATP/ADP ration, and platelet protein content were normal. Platelet and fibrinogen survival times with [75Se] selenomethionine were also normal, although platelets from VWD dogs incorporated more radioactivity than did those from normal dogs or from dogs with incomplete VWD.

Comparative study between endoscopy and radiology in acute upper gastrointestinal haemorrhage. (4/106)A total of 158 patients with acute upper gastrointestinal haemorrhage were studied, and the 53 patients on whom emergency endoscopies were performed were compared with the remaining 105. The cause of the bleeding was found in 51 of the endoscopy group and 39 of the control group. Three patients in the endoscopy group and 16 controls died. In the endoscopy group the correct preoperative diagnosis was made in all cases and there was less delay before operation. In the control group five patients had no diagnosis before operation, the preoperative diagnosis was wrong in nine, and five had laparotomies during which no cause of bleeding was found. The patients in the endoscopy group who did not have operations had a shorter stay in hospital than the controls. (+info)
Acute colitis in the renal allograft recipient. (5/106)Four renal allograft recipients with evidence of ischemic damage to the colon are presented and compared with 11 cases from 5 major series. Similarities in the patients included: deterioration of renal function, multiple immunosuppressive and antibiotic regimens, the use of cadaver renal allografts, and diagnostic and therapeutic measures requiring frequent enemas with barium and ion-exchange resins. Two of our patients underwent surgery for the removal of segments of necrotic colon after several weeks of fever and abdominal pain initially attributed to either acute rejection, viral infection, or pancreatitis. One patient had three days of melena and responded to non-operative therapy. The fourth patient developed ischemic colonic changes 10 weeks after allograft nephrectomy and was receiving no immunosuppression at the time. Broad spectrum antibiotics were used at various times in all patients. Early aggressive evaluation of gastrointestinal complaints--including barium enema, upper gastrointestinal series with small bowel follow-through, proctosigmoidoscopy or colonoscopy, and arteriography--is indicated, in view of the lethality of the complication of colonic ulceration. The clinical pictures presented emphasize the fact that recipients of renal allografts are commonly heir to many complications which may be considered rare in the normal population. (+info)
Post-transfusion purpura: a heterogeneous syndrome. (6/106)Three new patients with post-transfusion purpura (PTP) are described. As the manifestations in two differ significantly from those of previously reported cases, they serve to expand the definition of this syndrome. Although all 14 previously reported cases have occurred in Pl-A1-negative females, one of our patients was a Pl-A-negative male. Moreover, a female whose postrecovery platelets possessed the Pl-A1 antigen is described. Antiplatelet antibody activity was detected in all three patients by the 51Cr release test; in contrast, only one reacted in the complement (C) fixation assay. Serum obtained during the acute episode from the PlA1-positive patient reacted against platelets from four of 11 normals by C fixation and against platelets from 48 of 53 normals by 51Cr release, including five of nine Pl-A1-negative platelet samples. This case represents the first instance of PTP in which the platelet isoantibody was not specifically directed against the Pl-A1 antigen. These observations suggest that PTP may be a more heterogeneous disorder than previously realized. (+info)
Radiation enteritis: a rare complication of the transverse colon in uterine cancer. (7/106)Radiation therapy is a powerful method for the control of cancer. The utilization of abdominal or pelvic radiation has been extended, and the incidence of radiation enteritis appears to be increasing. The majority of the induced lesions is in the distal ileum, sigmoid colon, or rectum. Reported here is an unusual case of radiation enteritis which caused a severe sequelae of stricture in the transverse colon as a long-term effect of therapeutic irradiation for uterine cancer, and required a surgical resection.

Cooling for acute ischemic brain damage (cool aid): an open pilot study of induced hypothermia in acute ischemic stroke. (8/106)BACKGROUND AND PURPOSE: Hypothermia is effective in improving outcome in experimental models of brain infarction. We studied the feasibility and safety of hypothermia in patients with acute ischemic stroke treated with thrombolysis. METHODS: An open study design was used. All patients presented with major ischemic stroke (National Institutes of Health Stroke Scale [NIHSS] score >15) within 6 hours of onset. After informed consent, patients with a persistent NIHSS score of >8 were treated with hypothermia to 32+/-1 degrees C for 12 to 72 hours depending on vessel patency. All patients were monitored in the neurocritical care unit for complications. A modified Rankin Scale was measured at 90 days and compared with concurrent controls. RESULTS: Ten patients with a mean age of 71.1+/-14.3 years and an NIHSS score of 19.8+/-3.3 were treated with hypothermia. Nine patients served as concurrent controls. The mean time from symptom onset to thrombolysis was 3.1+/-1.4 hours and from symptom onset to initiation of hypothermia was 6.2+/-1.3 hours. The mean duration of hypothermia was 47.4+/-20.4 hours. Target temperature was achieved in 3.5+/-1.5 hours. Noncritical complications in hypothermia patients included bradycardia (n=5), ventricular ectopy (n=3), hypotension (n=3), melena (n=2), fever after rewarming (n=3), and infections (n=4). Four patients with chronic atrial fibrillation developed rapid ventricular rate, which was noncritical in 2 and critical in 2 patients. Three patients had myocardial infarctions without sequelae. There were 3 deaths in patients undergoing hypothermia. The mean modified Rankin Scale score at 3 months in hypothermia patients was 3.1+/-2.3. CONCLUSION: Induced hypothermia appears feasible and safe in patients with acute ischemic stroke even after thrombolysis. Refinements of the cooling process, optimal target temperature, duration of therapy, and, most important, clinical efficacy, require further study. (+info)
Melena is a medical term used to describe black, tarry stools. It is a sign of gastrointestinal bleeding that has been in the digestive system for a longer period of time, usually more than 24 hours. The black color is due to the presence of blood that has been exposed to stomach acid and has undergone chemical changes. Melena can be caused by a variety of conditions, including peptic ulcers, inflammatory bowel disease, esophageal varices (swollen veins in the esophagus), and cancer of the stomach or intestines. It is a serious condition that requires prompt medical attention, as it can lead to anemia, dehydration, and other complications.
Gastrointestinal hemorrhage, also known as GI bleeding, is a medical condition in which there is bleeding in the digestive tract, including the esophagus, stomach, small intestine, large intestine, rectum, or anus. The bleeding can be acute or chronic, and the severity can range from mild to life-threatening. The symptoms of gastrointestinal hemorrhage can include black or tarry stools, blood in the stool, abdominal pain, nausea, vomiting, weakness, dizziness, and fainting. The cause of gastrointestinal hemorrhage can be due to a variety of factors, including peptic ulcers, inflammatory bowel disease, gastrointestinal tumors, hemorrhoids, diverticulitis, and liver disease. Diagnosis of gastrointestinal hemorrhage typically involves a physical examination, blood tests, imaging studies such as endoscopy or colonoscopy, and sometimes angiography. Treatment of gastrointestinal hemorrhage depends on the underlying cause and the severity of the bleeding. It may include medications, endoscopic procedures, surgery, or a combination of these approaches.
Hematemesis is a medical term that refers to the vomiting of blood or blood-stained saliva. It is a symptom of a bleeding disorder in the digestive tract, usually in the stomach or esophagus. Hematemesis can be caused by a variety of conditions, including peptic ulcers, gastritis, esophageal varices, esophageal cancer, and stomach cancer. It can also be a complication of certain medications, such as aspirin or nonsteroidal anti-inflammatory drugs (NSAIDs). Hematemesis is a serious medical condition that requires prompt medical attention, as it can be a sign of a life-threatening bleeding disorder.
A diverticulum of the colon is a small pouch or sac that bulges out from the wall of the colon. It is a common condition that affects people of all ages, but is more common in older adults. Diverticula are usually small and do not cause any symptoms, but in some cases, they can become inflamed or infected, leading to diverticulitis. Diverticulitis is a medical emergency that requires prompt treatment with antibiotics and, in severe cases, surgery. Diverticula can also increase the risk of developing colon cancer, so it is important for people with diverticula to have regular colonoscopies to monitor their condition.
Ileal neoplasms refer to tumors or abnormal growths that develop in the ileum, which is the final section of the small intestine. The ileum is responsible for absorbing nutrients from digested food and eliminating waste products from the body. Ileal neoplasms can be either benign or malignant, and they can occur in people of all ages. Some common types of ileal neoplasms include adenomas, carcinoids, and lymphomas. Symptoms of ileal neoplasms may include abdominal pain, diarrhea, constipation, weight loss, and anemia. Diagnosis typically involves a combination of medical history, physical examination, imaging studies, and biopsy. Treatment for ileal neoplasms depends on the type, size, and location of the tumor, as well as the overall health of the patient. Options may include surgery, chemotherapy, radiation therapy, or a combination of these approaches. Early detection and treatment are important for improving outcomes and reducing the risk of complications.
Duodenal diseases refer to medical conditions that affect the duodenum, which is the first part of the small intestine. The duodenum is responsible for receiving and mixing food from the stomach with digestive enzymes and bile from the liver and gallbladder. Some common duodenal diseases include: 1. Duodenal ulcers: These are sores that develop in the lining of the duodenum or the stomach. They are often caused by the bacteria Helicobacter pylori and can lead to bleeding, pain, and other complications. 2. Duodenal diverticulosis: This is a condition in which small pouches or sacs form in the wall of the duodenum. It is usually asymptomatic but can cause complications such as bleeding, infection, and blockage. 3. Duodenal cancer: This is a rare type of cancer that develops in the cells lining the duodenum. It can cause symptoms such as abdominal pain, weight loss, and changes in bowel habits. 4. Duodenal strictures: These are narrowing or blockages in the duodenum that can be caused by inflammation, scarring, or other factors. They can lead to symptoms such as abdominal pain, vomiting, and difficulty swallowing. 5. Duodenal polyps: These are small growths that develop on the lining of the duodenum. Most are harmless, but some can be precancerous or lead to bleeding. Treatment for duodenal diseases depends on the specific condition and its severity. It may include medications, lifestyle changes, endoscopic procedures, or surgery.
Jejunal neoplasms refer to tumors or abnormal growths that develop in the jejunum, which is a part of the small intestine. The jejunum is located between the duodenum and the ileum, and it plays a crucial role in the digestion and absorption of nutrients from food. Jejunal neoplasms can be either benign or malignant, and they can occur in people of all ages. Benign neoplasms are non-cancerous and do not spread to other parts of the body, while malignant neoplasms, also known as carcinomas, are cancerous and can invade nearby tissues and spread to other parts of the body through the bloodstream or lymphatic system. Symptoms of jejunal neoplasms may include abdominal pain, nausea, vomiting, diarrhea, weight loss, and anemia. Diagnosis typically involves a combination of medical history, physical examination, imaging studies such as CT scans or MRI, and biopsy. Treatment for jejunal neoplasms depends on the type, size, and location of the tumor, as well as the overall health of the patient. Options may include surgery, chemotherapy, radiation therapy, or a combination of these approaches. Early detection and treatment are important for improving outcomes and reducing the risk of complications.
Jejunal diseases refer to medical conditions that affect the jejunum, which is the middle part of the small intestine. The jejunum is responsible for absorbing nutrients from digested food, and any disease that affects this part of the digestive system can lead to a range of symptoms and complications. Some common jejunal diseases include: 1. Jejunoileal Atresia: This is a birth defect in which the jejunum and ileum (the last part of the small intestine) do not connect properly, leading to malnutrition and other complications. 2. Jejunal Perforation: This occurs when a hole develops in the jejunum, allowing digestive contents to leak into the abdominal cavity. This can be caused by trauma, infection, or other factors. 3. Jejunal Ulcer: This is a sore or lesion that develops in the lining of the jejunum. It can be caused by a variety of factors, including infection, inflammation, or injury. 4. Jejunal Diverticulosis: This is a condition in which small pouches or sacs form in the lining of the jejunum. These sacs can become inflamed or infected, leading to pain, fever, and other symptoms. 5. Jejunal Cancer: This is a rare type of cancer that develops in the lining of the jejunum. It can cause a range of symptoms, including abdominal pain, weight loss, and changes in bowel habits. Treatment for jejunal diseases depends on the specific condition and its severity. In some cases, surgery may be necessary to remove damaged tissue or repair a perforation. Medications, such as antibiotics or anti-inflammatory drugs, may also be used to manage symptoms or treat underlying conditions.
Duodenal neoplasms refer to abnormal growths or tumors that develop in the duodenum, which is the first part of the small intestine. These neoplasms can be either benign (non-cancerous) or malignant (cancerous). Duodenal neoplasms can present with a variety of symptoms, including abdominal pain, nausea, vomiting, weight loss, and jaundice. The diagnosis of duodenal neoplasms typically involves a combination of imaging studies, such as endoscopy and CT scans, and biopsy to confirm the presence of cancer cells. Treatment for duodenal neoplasms depends on the type and stage of the cancer, as well as the patient's overall health. Options may include surgery, chemotherapy, radiation therapy, or a combination of these approaches. Early detection and treatment are important for improving outcomes and reducing the risk of complications.
Arteriovenous malformations (AVMs) are abnormal connections between arteries and veins that are not part of the normal circulatory system. These connections can cause blood to flow directly from arteries to veins, bypassing the capillaries where oxygen and nutrients are exchanged with the body's tissues. AVMs can occur anywhere in the body, but they are most commonly found in the brain, spinal cord, and liver. They can be congenital, meaning they are present at birth, or they can develop later in life. AVMs can cause a variety of symptoms, depending on their location and size. In the brain, they can cause headaches, seizures, and strokes. In the spinal cord, they can cause weakness, numbness, and paralysis. In the liver, they can cause abdominal pain, jaundice, and liver failure. Treatment for AVMs depends on the size, location, and symptoms they cause. Small AVMs may not require treatment, while larger ones may require surgery, radiation therapy, or embolization (a procedure in which a material is injected into the AVM to block blood flow).
An ulcer is a sore or open wound that forms on the surface of the skin, mucous membranes, or other tissues in the body. In the medical field, ulcers can occur in various locations, including the stomach, small intestine, large intestine, esophagus, and mouth. Stomach ulcers, also known as peptic ulcers, are the most common type of ulcer and are caused by a combination of factors, including the bacteria Helicobacter pylori, nonsteroidal anti-inflammatory drugs (NSAIDs), and stress. Small intestine ulcers are often caused by Crohn's disease or celiac disease, while large intestine ulcers are often caused by ulcerative colitis. Esophageal ulcers, also known as Barrett's esophagus, are caused by chronic acid reflux and can increase the risk of esophageal cancer. Mouth ulcers, also known as canker sores, are usually harmless and resolve on their own within a few days to a week. Treatment for ulcers depends on the location and cause of the ulcer. In some cases, antibiotics may be prescribed to treat H. pylori infection, while NSAIDs may be stopped or replaced with other medications. In severe cases, surgery may be necessary to remove the affected tissue.
Capsule Endoscopy is a minimally invasive medical procedure used to examine the lining of the small intestine. It involves swallowing a small, wireless camera capsule that takes images of the inside of the digestive tract as it passes through the body. The capsule is equipped with a battery and a wireless transmitter that sends images to a receiver worn around the patient's waist. The procedure is painless and does not require any sedation or anesthesia. Capsule endoscopy is often used to diagnose conditions such as Crohn's disease, celiac disease, and small intestine bleeding, which can be difficult to diagnose with traditional endoscopy methods.
