1/773. Delayed hemorrhage after nonoperative management of blunt hepatic trauma in children: a rare but significant event.PURPOSE: Nonoperative management of blunt hepatic injury (BHI) has become widely accepted in hemodynamically stable children without ongoing transfusion requirements. However, late hemorrhage, especially after discharge from the hospital can be devastating. The authors report the occurrence of serious late hemorrhage and the sentinel signs and symptoms in children at risk for this complication. methods: Nonoperative management of hemodynamically stable children included computed tomography (CT) evaluation on admission and hospitalization with bed rest for 7 days, regardless of injury grade. Activity was restricted for 3 months after discharge. Hepatic injuries were classified according to grade, amount of hemoperitoneum, and periportal hypoattenuation. RESULTS: Over 5 years, nonoperative management was successful in 74 of 75 children. One child returned to the hospital 3 days after discharge with recurrent hemorrhage necessitating surgical control. review of the CT findings demonstrated that he was the only child with severe liver injury in all four classifications. A second child, initially treated at an outside hospital, presented 10 days after injury with ongoing bleeding and died despite surgical intervention. Only the two children with delayed bleeding had persistent right abdominal and shoulder discomfort in the week after BHI. CONCLUSIONS: Our findings support nonoperative management of BHI. However, late hemorrhage heralded by persistence of right abdominal and shoulder pain may occur in children with severe hepatic trauma and high injury severity scores in multiple classifications.- - - - - - - - - - ranking = 1keywords = rate (Clic here for more details about this article) |
2/773. Reactive lymphoid hyperplasia of liver coexisting with chronic thyroiditis: radiographical characteristics of the disorder.BACKGROUND: Reactive lymphoid hyperplasia of the liver is an extremely rare entity, with six cases reported so far. methods: We encountered a 47-year-old Japanese female with reactive lymphoid hyperplasia of the liver, which coexisted with chronic thyroiditis. The lesion was discovered incidentally as a hypo-echoic mass with a hyper-echoic rim at a routine ultrasonography examination. It increased from 12 to 17 mm diameter in 6 months. Radiological studies, such as contrast-enhanced computerized tomography (CT) and angiography demonstrated a hypervascular lesion. RESULTS: It was consequently diagnosed as a neoplasm with malignant potentiality and she underwent partial hepatectomy. The lesion was composed of small mature lymphocytes which formed prominent lymphoid follicles with germinal centres, scattered plasma cells and stromal fibrosis. Immunohistochemical study revealed polyclonal origins of the involved lymphocytes. dna analysis for the immunoglobulin heavy gene and the T cell receptor beta gene using Southern blot hybridization showed no monoclonality. The following features have characterized the images in past cases, as well as ours: hypo-echoic mass, occasionally with a rim, in ultrasonography and hypervascularity, shown by angiography and enhanced CT.- - - - - - - - - - ranking = 1keywords = rate (Clic here for more details about this article) |
3/773. Isolated polycystic liver disease not linked to polycystic kidney disease 1 and 2.Autosomal dominant polycystic liver disease occurs commonly in association with autosomal dominant polycystic kidney disease, types 1 and 2. It may also exist as a separate entity, genetically distinct from autosomal dominant polycystic kidney disease types 1 and 2, as has been recently established to exist in a Belgian family. We report here a large Argentinian family of Spanish-Belgian ancestry with autosomal dominant polycystic liver disease, where proximal and distal markers for both polycystic kidney disease 1 and 2 failed to demonstrate genetic linkage. The data support the notion that polycystic liver disease and autosomal dominant polycystic kidney disease may have separate chromosomal loci.- - - - - - - - - - ranking = 3keywords = rate (Clic here for more details about this article) |
4/773. Nodular lymphoid lesion of the liver: an immune-mediated disorder mimicking low-grade malignant lymphoma.Three cases of unusual lymphoid infiltrate forming nodular macroscopic masses in the liver were studied in the authors' surgical pathology laboratory. These lesions posed difficulty in diagnosis, and their differentiation from low-grade lymphoma was not possible on histopathologic evaluation alone. The liver masses were analyzed histologically and immunohistochemically as well as for clonal immunoglobulin heavy chain (IgH) and T-cell receptor gamma (TCR-gamma) gene rearrangements. The lesions were seen as solitary grossly distinct firm nodules in all three patients, measuring 0.4, 0.7, and 1.5 cm, respectively, in their greatest dimensions. Two were found in livers removed because of end-stage primary biliary cirrhosis at the time of orthotopic liver transplantation, and the third was an incidental finding during laparotomy. Microscopically, these were nodules composed of small lymphocytes, plasma cells, and immunoblasts, with varying degrees of admixed acute inflammatory cells and scattered lymphoid follicles. By immunohistochemistry and molecular studies, these were found to be reactive lymphoid proliferations. All patients are alive and well at 2, 4, and 13 years, respectively. It is concluded that these cases represent a unique type of nodular lymphoid lesion, which is probably an immune-mediated benign reactive hyperplasia. It constitutes an entity by itself and must be distinguished from low-grade lymphoma. For a definitive diagnosis, immunohistochemistry and molecular studies are required.- - - - - - - - - - ranking = 1keywords = rate (Clic here for more details about this article) |
5/773. Adverse skin reaction from vitamin K1.Two patients with erythematous, tender, indurated plaques at the site of intramuscular injections of vitamin K1 are described. In one of these, condition was reproduced by the injection of a test dose. In both cases, there was associated liver disease. The red, indurated plaques cleared in 4-14 days. There have been two previous reports in the literature of similar lesions. Altough some of the patients showed sclerodermatous changes at the same site within 2 years of the injections. These unusual reactions have only been seen in patients with liver disease and when a variety of drugs have been administered. It may be that these factors are important in the initiation of the cutaneous response.- - - - - - - - - - ranking = 2keywords = rate (Clic here for more details about this article) |
6/773. Pseudolesion in segments II and III of the liver on CT during arterial portography caused by aberrant right gastric venous drainage.We report three cases of pseudolesions caused by aberrant right gastric venous drainage (AGVD) in segment II/III of the liver as demonstrated on CT during arterial portography (CTAP). On CTAP, the lesions were seen as wedge-shaped perfusion defects, and on hepatic arteriography, AGVD directed to the area with the perfusion defect was visible in all three cases. When a perfusion defect is detected at the edge of segments II/III at CTAP, a pseudolesion caused by AGVD should be suspected.- - - - - - - - - - ranking = 1keywords = rate (Clic here for more details about this article) |
7/773. Fibropolycystic disease of the hepatobiliary system and kidneys.This complicated case of fibropolycystic disease of the hepatobiliary system and kidneys was ably and incisively analyzed by Professor Sheila Sherlock. Her clinical acumen was revealed by her ability to differentiate congenital hepatic fibrosis, Caroli's disease, and adult polycystic disease of the liver and kidney. Interesting histologic features of this case included hepatic fibrosis with intact limiting plates anc central veins and the presence of bile plugs in the ducts, but the absence of bile statsis in the parenchyma. A percutaneous transhepatic cholangiogram demonstrated the dilated intrahepatic and extrahepatic ducts. Washing out the "gunk" from the biliary tract by T-tube drainage has great limitations in this type of case. Therefore, Dr. Adson suggested irrigation of the biliary ductal system using tubed placed transhepatically, plus a wide choledojejunostomy. Dr. Sherlock questioned this surgical approach. The use of chenodeoxycholic acid for this "gunk" was suggested. In spite of the dilated ducts and pathologic changes in the liver, the patient was not jandiced and did not have stones in her biliary tract. The genetics of this patient's problems was discussed.- - - - - - - - - - ranking = 1keywords = rate (Clic here for more details about this article) |
8/773. The diagnosis of subcapsular hematoma of the liver by scintigraphy.The diagnosis of subcapsular hematoma of the liver following blunt abdominal trauma has assumed clinical importance with recent reports of improved mortality with conservative management. There is increasing use of hepatic scintigraphy in evaluation of upper abdominal trauma. Two recently observed cases are used to illustrate the typical findings in this entity.- - - - - - - - - - ranking = 16.375406241768keywords = mortality, rate (Clic here for more details about this article) |
9/773. Acute coagulopathy following infusion of prothrombin complex concentrate.An acute coagulopathy developed in a 49 year old woman with severe liver disease after she received an infusion of prothrombin complex concentrate. The concentrate used in the infusion was subsequently studied by observing the effect of the concentrate on the partial thromboplastin times of various plasmas. The evidence suggests that activated coagulation factors, including activated factor X, were present in the concentrate, and probably played a role in initiating the acute change in the patient's coagulation status. Mechanisms whereby liver disease predisposes toward the development of such a coagulopathy are discussed. It would appear that prothrombin complex concentrates should be used in patients with liver disease only with utmost caution.- - - - - - - - - - ranking = 9keywords = rate (Clic here for more details about this article) |
10/773. The development of a pancreatic abscess, suppurative pylethrombosis, and multiple hepatic abscesses after a pancreatojejunostomy for chronic pancreatitis: report of a case.We present herein an autopsy case of 63-year-old Japanese man who died as a result of pancreatic abscess, suppurative pylethrombosis, and multiple liver abscesses that had developed 10 years after a pancreato- and cystojejunostomy with side-to-side anastomosis for chronic pancreatitis. Even after this operation, the patient had continued to consume excessive amounts of alcohol. He had first experienced back pain with leukocytosis 9 years after the operation, which relapsed the following year. Despite percutaneous transhepatic gallbladder drainage, his icterus had deteriorated into hepatic insufficiency. Computed tomographic scans of the abdomen had disclosed multiple liver abscesses. At autopsy, a pancreatic abscess and suppurative pylethrombosis as well as multiple liver abscesses were found. There have been few reported cases of such lethal complications developing after a pancreato- and cystojejunostomy for chronic pancreatitis. As the consumption of alcohol would have exacerbated the chronic pancreatitis, such patients should be strongly advised to abstain from drinking alcohol.- - - - - - - - - - ranking = 1keywords = rate (Clic here for more details about this article) |
