Evaluation of the Value of Fine Needle Aspiration Cytology and Cell Morphology in Determining the Histogenesis of Pancreatic Lesions With Review of Literature, Overview and Cytological Experience of 25 Years: Original Research.

Background And Aims: Benign lesions, inflammation, cysts and pseudocysts, as well as neoplasms of the exocrine and endocrine parts of the pancreas can be easily identified using cytological methods. The sensitivity and specificity can be increased with the help of additional examination methods. The sensitivity of intraoperative rapid cytology reaches about 99%.

[Interstitial lung disease in infancy and early childhood].

Diffuse interstitial lung disease of infancy (chILD) shows a spectrum of disease substantially different from that of adults. Established classification systems divide chILD into conditions that are more prevalent in infancy and conditions that occur at any age. The classification is based on a multidisciplinary approach including clinical, radiological, genetic, and histological findings.

Chronic progressive pulmonary paracoccidioidomycosis in a female immigrant from Venezuela.

Paracoccidioidomycosis (PCM) is a fungal infection caused by and . It is endemic to South and Central America. While PCM frequently remains latent, the disease can reactivate years after the initial infection.

Biocompatibility and Immunogenicity of Decellularized Allogeneic Aorta in the Orthotopic Rat Model.

The generation of a small-caliber arterial graft, utilizing a large vessel of a small animal, such as the aorta of the rat or rabbit, for clinical use in the peripheral arterial tree, can widen the options for arterial prostheses. This study demonstrated the ability of the decellularization protocol that was used to produce a noncytotoxic acellular small-caliber arterial graft, with sufficient biomechanical and biological integrity to withstand the demanding flow and pressure environment of the rat aorta. This work also demonstrated the superiority of the decellularized homograft over its intact counterpart, in terms of lower immunogenicity.

68Ga-DOTA-TATE PET/CT for Molecular Imaging of Somatostatin Receptor Expression in Metastasizing Epithelioid Hemangioendothelioma: Comparison With 18F-FDG.

Epithelioid hemangioendothelioma (EHE) is a rare tumor originating from vascular endothelial or pre-endothelial cells. It has the potential to metastasize. We present the case of a 51-year-old woman with metastasizing EHE who underwent both F-FDG and Ga-DOTA-TATE PET/CT for staging of disease and for evaluation of targeted radionuclide therapy potential.

PSMA Expression in Tumor Neovasculature Endothelial Cells of Follicular Thyroid Adenoma as Identified by Molecular Imaging Using 68Ga-PSMA Ligand PET/CT.

The prostate-specific membrane antigen (PSMA) is expressed by both prostate cancer and other neoplasms. We report the case of a 65-year-old man with castration-resistant metastatic prostate cancer who underwent Ga-PSMA ligand PET/CT for restaging of disease. Ga-PSMA ligand accumulation was noted in a thyroid lesion, suspicious for thyroid malignancy on complementary ultrasound.

Testosterone-receptor positive hepatocellular carcinoma in a 29-year old bodybuilder with a history of anabolic androgenic steroid abuse: a case report.

Background: Continuous use of anabolic androgenic steroid in high-doses is associated with substantial health risks, including hepatocellular adenoma. Malignant transformation from hepatocellular adenoma to hepatocellular carcinoma after anabolic androgenic steroid abuse has been rarely reported. The morphological distinction of adenoma from well-differentiated hepatocellular carcinoma is challenging and requires elaborated imaging techniques and histology.

Gray scale and contrast-enhanced ultrasound imaging of malignant liver tumors of vascular origin.

Objectives: Malignant vascular tumors of the liver are rare. The aim of this study was to investigate the applicability of gray scale and contrast-enhanced ultrasonography in patients with epithelioid hemangioendothelioma (EHE) of the liver and hepatic angiosarcoma (HA) and to describe the clinical presentation.

Methods: We retrospectively analyzed all patients with epithelioid hemangioendothelioma or hemangiosarcoma of the liver from 1998 to 2011, who underwent ultrasound investigation.

Wheeze in preschool age is associated with pulmonary bacterial infection and resolves after antibiotic therapy.

Background: Neonates with airways colonized by Haemophilus influenzae, Streptococcus pneumoniae or Moraxella catarrhalis are at increased risk for recurrent wheeze which may resemble asthma early in life. It is not clear whether chronic colonization by these pathogens is causative for severe persistent wheeze in some preschool children and whether these children might benefit from antibiotic treatment. We assessed the relevance of bacterial colonization and chronic airway infection in preschool children with severe persistent wheezing and evaluated the outcome of long-time antibiotic treatment on the clinical course in such children.

Grading of hypervascular hepatocellular carcinoma using late phase of contrast enhanced sonography - a prospective study.

Background: Outcome of patients with hepatocellular carcinoma is influenced by their histological grade. Invasive biopsy of the lesions is the gold standard in this regard.

Aims: We therefore analysed the diagnostic accuracy of contrast enhanced ultrasound for non-invasive grading of hypervascular hepatocellular carcinoma in liver cirrhosis.

Contact endoscopy for the evaluation of the pharyngeal and laryngeal mucosa.

Objectives: Contact endoscopy is a noninvasive tool that allows in vivo and in situ examination of superficial mucosa. Its use for early diagnosis of cancerous lesions of the oropharynx and larynx has not been evaluated. The aim of the study was to validate contact endoscopy for the examination of pharyngeal and laryngeal mucosa.

Losses of chromosome arms 4q, 8p, 13q and gain of 8q are correlated with increasing chromosomal instability in hepatocellular carcinoma.

Objective: Chromosomal instability is a key feature in hepatocellular carcinoma (HCC). Array comparative genomic hybridization (aCGH) revealed recurring structural aberrations, whereas fluorescence in situ hybridization (FISH) indicated an increasing number of numerical aberrations in dedifferentiating HCC. Therefore, we examined whether there was a correlation between structural and numerical aberrations of chromosomal instability in HCC.
