Prevalence and predicting factors of metabolic-associated fatty liver disease diagnosed by transient elastography with controlled attenuation parameters in HIV-positive people.

Metabolic disorders are increasing in people living with HIV (PLWH), and metabolic associated fatty liver disease (MAFLD) has become a common complication. A cross-sectional study was conducted in HIV-positive persons receiving anti-retroviral therapy (ART), in order to determine the prevalence and predicting factors of MAFLD in PLWH. All participants underwent bioelectrical impedance analysis, ultrasonography, and transient elastography with controlled attenuation parameter (CAP).

Added value of hepatobiliary phase gadoxetic acid-enhanced MRI for diagnosing hepatocellular carcinoma in high-risk patients.

Aim: To determine the added value of hepatobiliary phase (HBP) gadoxetic acid-enhanced magnetic resonance imaging (MRI) in evaluating hepatic nodules in high-risk patients.

Methods: The institutional review board approved this retrospective study and waived the requirement for informed consent. This study included 100 patients at high risk for hepatocellular carcinoma (HCC) and 105 hepatic nodules that were larger than 1 cm.

Ultrasound predictors of thyroid cancer.

Objective: To identify ultrasound (US) features associated with cancer in thyroid nodules.

Material And Method: During a two and a half-year period, medical charts, US images, and pathological findings in 629 consecutive patients with thyroid nodules who underwent US examination as well as fine needle aspiration biopsy (FNAB) or surgical excision or both were retrospectively reviewed. Clinical and US findings associated with thyroid cancer were identified using statistical models.

Impact and appropriateness of the emergency ultrasonography in a tertiary care hospital.

Objective: To quantify the notion of the impact of ultrasonography (US) on and the appropriateness of its use in, the diagnosis and treatment of emergency conditions.

Material And Method: A prospective study was conducted between September 2006 andApri 2007 at a tertiary care hospital. US was performed or supervised by experienced staff radiologists during the working hours and by final year radiology residents during the off-hours.

Supplement value of magnetic resonance imaging in small hepatic lesion (< or = 20 mm) detected on routine computed tomography.

Objective: To determine the supplemental MRI value in characterization of small hepatic lesions (< or = 20 mm) indetermined by routine CT scan.

Material And Method: This was a retrospective study. Sixty-four patients with 81 indeterminate small hepatic lesions on the CT scan were included in this study.

Assessment of gastrointestinal stromal tumors with computed tomography following treatment with imatinib mesylate.

Aim: To evaluate and characterize the patterns of disease progression of metastatic or unresectable gastrointestinal stromal tumor (GIST) treated with imatinib mesylate, and to determine the prognostic significance associated with disease progression.

Methods: Clinical data and computed tomography (CT) images were retrospectively reviewed in 17 GIST patients who were treated with imatinib mesylate from October 2002 to October 2006. Apart from using size measurement for evaluation of tumor response [Response Evaluation Criteria in Solid Tumors (RECIST) criteria], patterns of CT changes during treatment were evaluated and correlated with clinical data.

Primary hepatic clear cell myomelanocytic tumor. Case report and review of the literature.

A case of hepatic clear cell myomelanocytic tumor in a 31-year-old woman presenting clinically with abdominal pain is reported. Histopathologic examination showed a lesion characterized by a population of large epithelioid cells with clear or eosinophilic granular cytoplasm, rich in glycogen. Immunohistochemically, the tumor cells were positive for HMB-45, Melan-A and muscle-specific actin, but negative for epithelial markers, desmin, S-100 protein, and neuroendocrine markers.

Abdominal manifestation and complications in systemic lupus erythematosus: emphasis on CT findings.

Objective: To describe computed tomography (CT) features in SLE patients with suspected abdominal involvement or complications.

Material And Method: SLE Patients who presented with suspected abdominal involvement or complications and underwent CT between 2001 and 2005 were retrospectively reviewed. All CT studies were performed within 21 days of the onset of symptoms.

Combined hepatocellular and cholangiocarcinoma: CT findings with emphasis on multiphasic helical CT.

Objective: To describe CT findings of patients with combined hepatocellular carcinoma and cholangiocarcinoma (HCC-CC) in correlation with clinical data and histopathological results.

Material And Method: Ten from 31 cases whose CT study was available were reviewed retrospectively in the aspect of imaging findings, clinical data, and pathological results.

Results: Most of the tumors were hypodense solitary mass with gradually enhanced after contrast administration.

The efficacy of roselle (Hibicus sabdariffa Linn.) flower tea as oral negative contrast agent for MRCP study.

Objective: To evaluate the efficacy of roselle flower tea (RFT) administration as oral negative contrast agent for MRCP study.

Material And Method: Roselle flower tea was prepared by packing 4,000 mg of dry ground roselle flower in a tea bag and soaked with 480 ml of hot distilled water RFT was tested in phantom, volunteer subjects and was studied in patients for MRCP study. Quanlitative analysis was made by evaluation of the conspicuity of biliary system after RFT administration.

Factors predisposing to peptic ulcer disease in asymptomatic cirrhotic patients.

Background: There is a high prevalence of peptic ulcer in cirrhotic patients, but the pathogenesis of peptic ulcer in cirrhosis remains inconclusive.

Aim: To investigate factors associated with peptic ulcer and to evaluate peptic ulcer prevalence in asymptomatic cirrhotic patients.

Methods: A total of 130 cirrhotics were recruited into the study for endoscopic screening.
