Current management of hemorrhage in cirrhotic patients is disappointing, probably because it deals only with the portal hypertension, while the coagulation disorders are neglected. Some new suggestions can be made : 1) Hemorrhage originates in coagulation disorders. The mechanical lesion of the mucosa is only the opportunity for these disorders to become apparent. The lesion may be : infrequently, a ruptured esophageal varix or a gastroduodenal peptic ulcer ; a lesion of the cardia (hiatal hernia, reflux, esophagitis, minimal traumatic tears) ; a gastric anomaly (hemorrhagic gastritis, superficial ulcerations, petechiae) ; in some cases no mucosal lesion is apparent. 2) Any widespread liver disease results in lasting hypercoagulability which is responsible for : permanent lysis, consumption, DIC. The spleen is responsible for the functional alteration of the platelets. Splenectomy is followed by permanent recovery. 3) Changes involving the platelets are responsible for most hemorrhages. Thrombopenia and severe anomalies of platelet aggregation are common findings in liver cirrhosis. Further deterioration can be induced by acetylsalicylic acid, especially if it is absorbed after an immoderate ingestion of alcohol. Emergency treatment consists in platelet transfusions. 4) Stasis in the portal system may, however, result in permanent activation of coagulation. 5) Cirrhosis results in chronic hypercoagulability and severe platelet deterioration. Any stress involving coagulation mechanisms may therefore induce hemorrhage : infection, acetyl salicylic acid, respiratory distress, estrogens, massive transfusion. It is always dangerous to "feed" consumption or to restrain lysis. 6) Coagulation tests should be performed rapidly, in order to evaluate hypercoagulability, consumption, lysis, and evidence of DIC ; FDP can probably be responsible for inflammatory changes in the liver and spleen. 8) Coagulation disorders are permanent since the hepatic alterations are irreversible.

The coagulation parameters of fourteen patients with advanced liver cirrhosis (3 in Child class B and 11 in class C) were prospectively determined quarterly for one year in order to evaluate the possible relationship between high D-dimer levels and incidence of disseminated intravascular coagulation (DIC) and of gastrointestinal bleeding. The values of D-dimer, fibrin(ogen) degradation products, platelets, fibrinogen, prothrombin activity and antithrombin III were fairly stable in almost all patients and no patient developed an overt DIC; one patient had a significant increase in D-dimer three months after the first control. During the one year follow-up, four patients died, one by the occurrence of hepatocellular carcinoma and three by digestive bleeding. Overall, four patients had upper digestive tract bleeding, three from esophageal varices and one from hemorrhagic gastritis. Hemorrhage was more frequent in patients with high D-dimer levels (3/7, 43%) than in patients with normal D-dimer levels (1/7, 14%). In conclusion, the detection of high D-dimer levels in patients with advanced cirrhosis is not predictive for the occurrence of a overt DIC but seems to be related with an increased risk of gastrointestinal bleeding.

We report an autopsy case of severe portal hypertensive gastropathy with a large shunt from the superior mesenteric to left renal vein in a patient with alcoholic liver cirrhosis. A 60-year-old man with alcoholic cirrhosis was admitted for tarry stool and ascites. Endoscopic finding revealed multiple red spots and hemorrhagic gastritis at prepylorus of the stomach. Angiography showed a large shunt vessel originating from the superior mesenteric to left renal vein. He died of hepatic failure and DIC following frequent gastrointestinal bleeding. At autopsy, the stomach showed marked congestion of the capillary vessels in the tunica propria mucosa. This finding showed that the gastropathy resulted in the congestion of the gastric veins connecting with the large shunt vessel.

There are many common and significant medical complications of head injury. These include (1) cardiovascular problems such as hyperdynamic state, myocardial injury, and dysrhythmias; (2) respiratory changes such as neurogenic pulmonary edema, hypoxia, abnormal ventilatory patterns, pulmonary infections, and pulmonary emboli secondary to deep vein thrombosis; (3) consumption coagulopathy; (4) water and electrolyte derangements--hypo- and hypernatremia; (5) hypothalamic/pituitary dysfunction--syndrome of inappropriate secretion of antidiuretic hormone and diabetes insipidus; (6) increased general metabolism with loss of immunocompetence, respiratory compromise, and complications of decreased activity; (7) gastrointestinal difficulties, particularly stress gastritis; and (8) infectious problems including those related to contamination from open wounds and foreign bodies such as monitors.

We report the first case in a preterm infant given oral sulindac for treatment of symptomatic patent ductus arteriosus who subsequently developed severe acute haemorrhagic gastritis leading to disseminated intravascular coagulation, massive pulmonary haemorrhage and death. The postmortem examination suggested that the mechanism was likely a direct irritant insult causing ischaemia on the gastric mucosa. Although sulindac is supposed to be a renal-sparing non-steroidal anti-inflammatory prodrug associated with minimal renal and gastrointestinal adverse effects, clinicians should be alerted to this potential life-threatening complication in preterm infants. Until the question of safety could be adequately addressed, the use of sulindac for ductal closure should remain experimental.

Acetazolamide (Diamox) is a carbonic anhydrase inhibitor commonly used in patients with glaucoma in order to reduce intraocular pressure. Acetazolamide (AZ) is mostly excreted in the urine, therefore, the blood levels of AZ often tend to increase in patients with chronic renal failure. We experienced a case of chronic renal failure in a patient suffering from acute hemorrhagic gastritis associated with AZ intoxication. A 66-year-old female with chronic renal failure was referred to our hospital because of drowsiness and an acute deterioration of renal function. She had been treated with AZ, 500 mg per every day for eleven days for the treatment of glaucoma. Laboratory studies showed leukocyturia, thrombocytopenia, severe anemia, and tarry stools. The serum concentration of AZ was elevated to a maximum of 76.5 mg/ml. She was thus diagnosed as having AZ intoxication. On further examination, acute extensive hemorrhagic gastritis was also found by gastroscopy. Despite of the administration of intensive therapies, she died of disseminated intravascular coagulation (DIC) and septic shock due to bone marrow depression 6 days after admission. It is generally known that excessive blood levels of AZ inhibit not only the gastric juices but also prostaglandin levels and HCO3- excretion in the gastric mucosal barrier. We thus concluded that an excessive dose of AZ had probably destroyed the gastric mucosal barrier or thrombocytopenia due to bone marrow disorder and thus eventually led to the development of hemorrhagic gastritis. As far as we know, this is the first case report of acute hemorrhagic gastritis associated with AZ intoxication. Even though AZ tends to strongly bind to plasma protein and its clearance is generally poor by hemodialysis (HD), in our patient, HD was observed to be rather effective since the clearance of AZ was 45.8 ml/min on HD and 66 ml/min on direct hemoperfusion (DHP). DHP often reduces the number of platelets, also DHP needs a lot of heparin, therefore, we should have performed HD alone instead of DHP. In patients with an impaired renal function, AZ should therefore be administered very carefully in order to avoid an accumulation of the drug. In addition, HD alone should be used to remove any excessive amounts of AZ from the blood.

An enzymatic, kinetic method for determining serum lipase activity was evaluated and compared to a standard manual method for use in dogs. The kinetic method was a commercial kit adapted for use on a tandem access clinical chemistry analyzer and utilized a series of coupled enzymatic reactions based on the hydrolysis of 1,2-diglyceride by lipase. The manual method was the Cherry-Crandall technique based on the titration of base against the acid formed by hydrolysis of an olive oil substrate by lipase. The correlation between the two methods was very good (r = 0.94). The reference range for 56 clinically healthy dogs assayed by the kinetic method was 90 to 527 U/L. Diseases associated with a greater than twofold elevation in serum lipase activity as determined by the kinetic method included pancreatitis, gastritis with liver disease, and oliguric renal failure with metabolic acidosis. In some cases, pancreatitis was seen with other clinical problems, such as gastroenteritis, diabetic ketoacidosis, duodenal mass, disseminated intravascular coagulation, and septic peritonitis. Diseases associated with serum lipase activity within the reference range or elevated less than twofold included gastritis, gastric ulcer, cholestasis, phenobarbital-induced hepatopathy, colitis, copper hepatopathy, abdominal hematoma, apocrine gland adenocarcinoma, and thrombocytopenia with pneumonia.

An adult male chinchilla (Chinchilla lanigera) presented with severe lethargy and tachypnea; the physical examination was otherwise unremarkable. Due to the animal's clinical condition, it was submitted for necropsy but died immediately prior to euthanasia. Clinicopathologic findings included leukocytosis with a left-shift neutrophilia and lymphopenia, azotemia, hyperphosphatemia, hyperglycemia, hyperlipemia, electrolyte imbalance, cholestasis, and hepatocellular damage. Neutrophilic enteritis with gramnegative bacterial colonization, hepatic lipidosis, interstitial pneumonia, suppurative tubulonephritis, erosive gastritis, cerebral edema, and lymphoid depletion were present microscopically. Attaching and effacing, eae-positive, Escherichia coli characterized by the presence of the intimin virulence factor was isolated from both the kidney and spleen. The cause of death was attributed to acute E. coli septicemia and subsequent disseminated intravascular coagulation.

Primary Hyperparathyroidism (PHP) is a rare event in pregnancy; Maternal complications in PHP patients can be as high as 67%. It can be overlooked easily because of many similar complaints shared by hyperparathyroidism and pregnancy such as nausea and vomiting, gastritis, bone aches, easy fatigability. Hypercalcemic crisis can develop resulting in coma and death. Neonatal effects are tetany and death in about 80% of cases. We report a case, of an antenatal woman at 30 weeks gestation with complains of painful swelling in left lower jaw and below right knee, pain over right hip joint and frequent episodes of gastritis. She was finally diagnosed to have primary hyperparathyroidism and brown tumour due to parathyroid adenoma. The baby was kept in Neonatal Intensive Care Unit (NICU) for three weeks, in view of prematurity with respiratory distress and later developed sepsis with DIC. The patient's signs and symptoms regressed after parathyroid surgery and the baby was healthy at the time of discharge. This case highlights the progressive deterioration of the patient because of lack of awareness of this disease process and its impact on maternal and foetal morbidity.
