A 12-year-old girl underwent laparoscopy-assisted splenectomy and cholecystectomy with removal of her spleen through a small Pfannenstiel incision. She had an unremarkable postoperative course but returned 16 days later because of increasing right-sided abdominal pain. The pain was constant, sharp, and stabbing without radiation. Abdominal examination showed diffuse right upper quadrant and epigastric tenderness without peritoneal irritation. Laboratory test results included white blood cell count, 14.4 x 10(9)/mm3; hemoglobin, 8.5 g/dL; platelets, 1,483,000; and normal values for lipase, amylase, aspartate transaminase, and alanine transaminase. Evaluation with ultrasonography and vessel Doppler studies showed an occlusive thrombus throughout the portal and splenic veins. The patient underwent intravenous heparin anticoagulation therapy. Her symptoms resolved completely over the next 2 days. The patient is currently receiving warfarin and anagrelide as an outpatient (international normalized ratio, 2). There were no long-term complications caused by portal vein thrombosis. This is the first reported case of portal vein thrombosis after laparoscopic splenectomy in the pediatric population.

We report on a 68-year-old female patient who was admitted with abdominal pain. Elevated lipase and CRP caused us to suspect pancreatitis. Because an enlarged pancreas head was found on ultrasound, an endoscopic retrograde cholangio- and pancreaticography was performed with a pethidine-containing premedication. Thereafter, bilirubin, gamma-glutamyl transpeptidase and alkaline phosphatase increased dramatically. There was also a moderate elevation of aspartate aminotransferase and alanine aminotransferase. A second endoscopic retrograde cholangio- and pancreaticography with the same premedication was performed in order to exclude an undetected concretion. This led to a further increase of bilirubin. An association with the drugs given as premedication was therefore suspected, and in fact, a hypersensitivity reaction towards pethidine was confirmed by the lymphocyte transformation test. We thus conclude that pethidine caused an immunologically mediated hepatic injury.

Portal vein thrombosis (PVT) has rarely been documented in patients after splenectomy for gastric malignancy. We report a case of PVT that occurred after splenectomy as part of an en-bloc node dissection performed to treat gastric malignant lymphoma. A 38-year-old man underwent total gastrectomy and splenectomy with en-bloc D2 lymph node dissection. The spleen weighed 480 g. On postoperative day (POD) 31, the patient complained of abdominal pain in the right upper quadrant accompanied by fever. Moderate elevations of C-reactive protein (CRP), aspartate transaminase (AST), and alanine transaminase (ALT) were noted. Contrast-enhanced computed tomography (CT) and ultrasonography disclosed thrombus in the portal vein and the splenic vein. There were no abnormalities in the levels of lupus anticoagulant, protein C antigen, protein S antigen, or antithrombin III (AT III). A diagnosis of PVT was made, and prompt treatment, including intravenous heparin combined with tissue plasminogen activator (tPA) was initiated, followed by longterm warfarin. This treatment resulted in clinical improvement, but failed to achieve thrombolysis in the portal vein. At follow-up after 6 months, the patient complained of postprandial abdominal pain with persistent peripheral edema and ascites. This case indicates that splenectomy for en-bloc node dissection in gastric malignancy is a possible cause of PVT. Because both the symptoms and the laboratory data in PVT are nonspecific, a high level of clinical suspicion and a low threshold for obtaining imaging examinations are important in the early diagnosis of PVT. Surgeons should remember PVT among several other complications whenever patients treated with radical gastrectomies are symptomatic and imaging studies are considered necessary.

Hyperamylasemia has been reported in more than 65% of patients with severe leptospirosis, and the true diagnosis of acute pancreatitis is complicated by the fact that renal failure can increase serum amylase levels. Based on these data we retrospectively analyzed the clinical and histopathological features of pancreas involvement in 13 cases of fatal human leptospirosis. The most common signs and symptoms presented at admission were fever, chills, vomiting, myalgia, dehydratation, abdominal pain and diarrhea. Trombocytopenia was evident in 11 patients. Mild increased of AST and ALT levels was seen in 9 patients. Hyperamylasemia was recorded in every patient in whom it was measured, with values above 180 IU/L (3 cases). All patients presented acute renal failure and five have been submitted to dialytic treatment. The main cause of death was acute respiratory failure due to pulmonary hemorrhage. Pancreas fragments were collected for histological study and fat necrosis was the criterion used to classify acute pancreatitis. Histological pancreatic findings were edema, mild inflammatory infiltrate of lymphocytes, hemorrhage, congestion, fat necrosis and calcification. All the patients infected with severe form of leptospirosis who develop abdominal pain should raise the suspect of pancreatic involvement.

Eight cases of feline pancreatic adenocarcinoma and two cases of pancreatic adenoma were reviewed. The adenomas were incidental findings. Most cats with adenocarcinomas had anorexia (75%) and vomiting (63%), while 38% had abdominal pain, a palpable abdominal mass, and/or jaundice. Diagnostic abnormalities included leukocytosis, hyperglycemia, increased alanine aminotransferase activity, poor serosal detail on abdominal radiography, and an abdominal mass effect on ultrasonography. The majority of cats with carcinomas had metastases (mostly to liver, lung, and small intestine), and all were euthanized or died within 7 days of diagnosis. Clinically, feline pancreatic carcinoma may be difficult to distinguish from feline pancreatitis.

Between the dates of May 4th-August 6th 2002, 46 cases were detected with abdominal pain nausea, vomiting, arthralgia/myalgia, headache, fever, diarrhea and rash, in the middle Blacksea and north inner Anatolia regions. Their laboratory findings yielded elevated levels of liver enzymes (AST, ALT, LDH), leucopenia and thrombocytopenia. As the infection was treated easily with tetracyclines, clinical diagnosis was considered to be rickettsiosis or ehrlichiosis. Serum and blood samples obtained from some of the patients were tested against Rickettsia, Ehrlichia, Leptospira and Coxiella, in the national and international laboratories. Samples from 19 patients were sent to National Reference Centre and WHO Collaborating Centre for Rickettsial Reference and Research Laboratory, France, and 7 of them were reported as acute Q fever while 8 of them were reported as passed Q fever (QF) cases. In May 2003, new cases with similar symptoms have been reported from the same regions, with different epidemiologic and serologic findings (tick exposure history was higher, response to tetracycline was lower, C. burnetii antibodies were negative), indicating a viral etiology. The samples of these patients have been sent to National Reference Centre and WHO Collaborating Centre for Arboviruses and Viral Heamorrhagic Fevers, France, and the initial reports were marked as Crimean Congo hemorrhagic fever virus (CCHFV). Then the serum samples of previous 26 patients which were stored in National Serum Bank have been retrospectively investigated for viral aetiology in the same center, and 17 of them have been found positive for CCHFV IgM antibodies. Four of these patients were diagnosed as acute QF in 2002, one was passed QF, 2 were negative for QF and 10 were patients not investigated for QF. As a result, the detection of the both infections together in the same area shows the essential need for further epidemiological investigations.

A study in healthy men and women was performed to assess the safety, tolerability, pharmacokinetics (PK) and pharmacodynamics (PD) of orally administered recombinant human interleukin-11 (oprelvekin) (OAO). Four cohorts of 10 subjects each received 3, 5, 10 or 30 mg (8:2/OAO:placebo ratio), first as a single dose with a 7-day washout period, then 7 consecutive daily doses. Safety was assessed by ongoing evaluation of adverse events (AEs) and laboratory values. PK samples were collected on the first and last day of dose administration. The established effects of subcutaneous oprelvekin on C-reactive protein (CRP, upward arrow), platelet count (upward arrow), fibrinogen (upward arrow) and hemoglobin (downward arrow), were evaluated. PK analysis showed that most subjects (27/34, 79%) had undetectable serum levels of IL-11. PD measures showed no changes from baseline between any OAO group and the placebo group. Orally administered oprelvekin was safe and well tolerated at all doses. A total of five AEs (abdominal pain, diarrhea, headache, rhinitis, grade 3 alanine aminotransferase elevation) were reported across all groups. Evaluations of serum IL-11 levels indicate that OAO is not systemically absorbed at levels above the lower limit of the bioanalytic assay. These data in addition to the lack of effect on PD measures suggest that there is a decreased potential of systemic adverse events with OAO.

Childhood NAFLD has become an important childhood liver disease, and it is probably highly prevalent. The full of spectrum of NAFLD has been identified in children. It is not currently known whether or not simple hepatic steatosis in children is benign or whether it evolves to NASH over time. In contrast, childhood NASH certainly can have serious consequences. Cirrhosis is apparently rare in children with NAFLD, but it definitely occurs. Childhood NAFLD may occur in very young children, and there is no female predominance in the pediatric age bracket. Children present with vague abdominal pain, if they have any symptoms at all, but frequently hepatic steatosis is found incidentally on abdominal imaging. Laboratory studies show that serum aminotransferase abnormalities are rather moderate, with serum alanine aminotransferase (ALT) more elevated than serum aspartate aminotransferase (AST). Hypertriglyceridemia is the typical blood lipid abnormality, although hypercholesterolemia may occur. NASH may be more severe in children from certain ethnic groups, including Hispanics and Asians, or in association with certain metabolic disorders characterized by abnormalities in insulin receptor structure or signaling, such as lipodystrophy syndromes. Weight loss through dietary redesign and a regimen of regular exercise remains the mainstay for treatment for childhood NAFLD. A dietary strategy to minimize postprandial hyperinsulinemia and overall fat intake, such as a low glycemic index diet, may be the best dietary strategy. The real efficacy of drug treatments in children requires further investigation. The overriding message is that childhood obesity poses important health problems, including but not limited to potentially severe chronic liver disease. Early diagnosis of children who are only overweight is a worthy goal so that strategies to limit obesity can be instituted as early as possible. Identification of genetic risks is important, but management will invariably require changes in environmental factors. In addition to individual treatment, a multifaceted, societal initiative is required for solving the childhood obesity epidemic.

Clinical features of Dengue are very variable due to multiple alterations induced by the virus in the organism. Increased levels of transaminases similar to those produced by the Hepatitis virus have been reported in patients with Dengue from hiperendemic zones in Asia. The objectives of this study were to determine alterations in the liver tests in patients with Dengue and to relate them to the disease, clinically and serologically. Clinical history, hemathological tests serum transaminases (ALT y AST) and bilirubin assays were performed in 62 patients with clinical and serological diagnosis of Dengue. According to clinical features 38.7% of the patients with classical (CD) and hemorrhagic (DHF) forms of Dengue reffered abdominal pain and 2 patients with DHF had ictericia and hepatomegaly. Laboratory test findings showed leucopenia in 72.5% in both forms of Dengue and of patients with DHF severe thrombocytopenia (< 50.000 platelets x mm3), long PT and PPT in 70.9%, 23.0% and 42.3%, respectively. Transaminase values five fold higher than the normal values (p < 0.005) were observed in 36.8% and 74.4% of patients with CD and DHF respectively; AST was predominant in both groups. Our results suggest liver damage during the course of Dengue. A differential diagnosis has to be done between the hepatic involvement of Dengue cases and others viral diseases with hepatic disfunctions.

We report here on a case of non-Hodgkin's lymphoma in which liver involvement was the predominant clinical manifestation. A healthy 44-year-old man presented with upper abdominal pain, hepatosplenomegaly, thrombocytopenia, elevated AST, ALT and bilirubin, and marked elevation of lactate dehydrogenase and alkaline phosphatase. The abdominal CT scan showed only diffuse hepatosplenomegaly and uneven contrast enhancement of the spleen without any definite mass of the liver and spleen. US-guided aspiration biopsy of liver and the histologic examination confirmed a diagnosis of non-Hodgkin's lymphoma, the diffuse large B cell type. Bone marrow biopsy showed the infiltration of malignant lymphoma cells. PET-CT showed an increased FDG uptake of the liver, spleen and long bones. The patient was treated with combination regimen of cyclophosphamide, doxorubicin, vincristine and prednisone chemotherapy. Even in the absence of a mass lesion or lymphadenopathy, primary hepatic or hepatosplenic lymphoma should be considered in differential diagnosis of hepatitis or liver cirrhosis, especially for patients with diffuse hepatosplenomegaly and markedly elevated LDH.
