Risk prediction of hepatitis B virus-related hepatocellular carcinoma in the era of antiviral therapy.

Hepatocellular carcinoma (HCC) is a grave primary liver cancer that has a limited therapeutic option because it is generally diagnosed later in an advanced stage due to its aggressive biologic behavior. The early detection of HCC has a great impact on the treatment efficacy and survival of patients at high risk for cancer. Potential host, environmental, and virus-related risk factors have been introduced. Hepatitis B virus (HBV) is a major cause of end-stage liver diseases such as liver cirrhosis or HCC in endemic areas, and its serologic or virologic status is considered an important risk factor. HCC risk prediction derived from the identification of major risk factors is necessary for providing adequate screening/surveillance strategies to high-risk individuals. Several risk prediction models for HBV-related HCC have been presented recently with simple, efficient, and readily available to use parameters applicable to average- or unknown-risk populations as well as high-risk individuals. Predictive scoring systems of risk estimation to assess HCC development can provide the way to an evidence-based clinical approach for cost- and effort-effective outcomes, capable of inducing a personalized surveillance program according to risk stratification. In this review, the concepts and perspectives of the risk prediction of HCC are discussed through the analysis of several risk prediction models of HBV-related HCC.

Transient carnitine transport defect with cholestatic jaundice: report of one case in a premature baby.

Carnitine (ß-hydroxy-γ-trimethylaminobutyric acid) is involved in the transport of long-chain fatty acids into the mitochondrial matrix and the removal of potentially toxic acylcarnitine esters. Transient carnitine transport defect is a rare condition in newborns reported in 1/90,000 live births. In this paper, we describe a case of transient carnitine transport defect found in a premature baby who had prolonged cholestatic jaundice and poor weight gain, and who responded dramatically to oral carnitine supplementation.

Comparison of the accuracy of neutrophil CD64 and C-reactive protein as a single test for the early detection of neonatal sepsis.

PURPOSE: Early identification of neonatal sepsis is a global issue because of limitations in diagnostic procedures. The objective of this study was to compare the diagnostic accuracy of neutrophil CD64 and C-reactive protein (CRP) as a single test for the early detection of neonatal sepsis. METHODS: A prospective study enrolled newborns with documented sepsis (n=11), clinical sepsis (n=12) and control newborns (n=14). CRP, neutrophil CD64, complete blood counts and blood culture were taken at the time of the suspected sepsis for the documented or clinical group and at the time of venipuncture for laboratory tests in control newborns. Neutrophil CD64 was analyzed by flow cytometry. RESULTS: CD64 was significantly elevated in the groups with documented or clinical sepsis, whereas CRP was not significantly increased compared with controls. For documented sepsis, CD64 and CRP had a sensitivity of 91% and 9%, a specificity of 83% and 83%, a positive predictive value of 83% and 33% and a negative predictive value of 91% and 50%, respectively, with a cutoff value of 3.0 mg/dL for CD64 and 1.0 mg/dL for CRP. The area under the receiver-operating characteristic curves for CD64 index and CRP were 0.955 and 0.527 (P<0.01), respectively. CONCLUSION: These preliminary data show that diagnostic accuracy of CD64 is superior to CRP when measured at the time of suspected sepsis, which implies that CD64 is a more reliable marker for the early identification of neonatal sepsis as a single determination compared with CRP.

Hypothyroidism during antithyroid drug treatment with methimazole is a favorable prognostic indicator in patients with Graves' disease.

BACKGROUND: A major problem with antithyroid drug (ATD) therapy in Graves' disease is the high relapse rate. Therefore, clinicians have sought prognostic indicators of permanent remission. Suppression of serum thyrotropin (TSH) when ATD therapy is stopped carries a poor prognosis, but little is known regarding the significance of elevated serum TSH concentrations in the course of ATD therapy. The objective of this study was to determine if elevated serum TSH concentrations during methimazole (MMI) therapy is associated with a favorable long-term prognosis. METHODS: We retrospectively studied patients with Graves' disease who were initially on MMI, in whom this drug was stopped because they had undetectable thyroid-stimulating antibodies (TSAbs) or were euthyroid after at least 24 months on MMI treatment. A strategy of high MMI doses plus T4 was not used in these patients. We identified 40 patients with elevated serum TSH concentration (>10 microIU/mL) during MMI therapy (H-TSH group). Eighty-five percent of the H-TSH group had negative tests for TSAb. The H-TSH group was sex- and age-matched with 37 patients who had similar selection criteria, but did not have elevated serum TSH concentration during MMI therapy (N-TSH group). The H-TSH and N-TSH groups were similar in gross thyroid size, percentage of patients with exophthalmos, serum free thyroxine, duration of MMI treatment, TSAb status, duration that their TSAb tests remained negative, and thyroid peroxidase antibody titers. The patients were followed for 24 months after stopping MMI. RESULTS: In the H-TSH group, MMI-associated hypothyroidism typically occurred after 7-8 months of treatment with daily doses of 10-15 mg MMI. No patient had severe symptoms of hypothyroidism. The percentage of patients in remission at 6, 12, and 24 months after discontinuation of MMI was 90.0, 87.5, and 85.0, respectively, in the H-TSH group and 70.3, 67.6, and 54.1, respectively, in the N-TSH group (p < 0.05 for the comparison of groups at 6 and 12 months and p < 0.001 for comparison of the groups at 24 months). CONCLUSIONS: In patients with Graves' disease who are treated with MMI for at least 2 years and become euthyroid, the occurrence of elevated serum TSH concentrations during MMI treatment is a favorable indicator for long-term remission and is independent of multiple other factors including TSAb status, duration of MMI treatment, and gross parameters of goiter size.

Cardiac problems in mad-honey intoxication.

Mad-honey disease or honey intoxication is caused by consuming honey produced from leaves and flowers of the Rhododendron family. Here a case of honey intoxication with cardiac involvement is reported.
