Testicular persistence of Parvovirus B19: evidence for preferential infection of germ cell tumors.

Human Parvovirus B19 has previously been implicated in the pathogenesis of testicular germ cell tumors, but this could not have been confirmed. This study was designed to investigate the testicular persistence of Parvovirus B19 and possible associations with germ cell tumors. Paraffin-embedded or fresh tissues from 36 germ cell tumors, 20 germ cell aplasias, 26 normal testicular tissues, 20 liver tissues, and 20 spleen tissues were evaluated by two different molecular assays: a nested PCR for Parvovirus B19 capsid genes and a commercial quantitative real-time PCR.

Predictive factors for postoperative outcome in temporal lobe epilepsy according to two different classifications.

Purpose: The determination of prognostic factors is important for predicting outcome after epilepsy surgery. We investigated the factors related to surgical outcome within a homogeneous group of patients suffering from pathologically proven mesial temporal lobe epilepsy with hippocampal sclerosis (MTLE-HS), and compared Engel's outcome classification system with the latest one proposed by the ILAE.

Method: We included 109 patients with MTLE-HS who were followed-up for at least 1 year after epilepsy surgery.

Protein carbonyl levels in serum and gingival crevicular fluid in patients with chronic periodontitis.

Objective: Evidence reveals the role of reactive oxygen species (ROS) in many pathologies including periodontitis. Protein carbonylation is the most widely used biomarker for oxidative damage to proteins, and reflects cellular damage induced by ROS. In this study protein carbonyl (PC) levels in serum and gingival crevicular fluid (GCF) in patients with chronic periodontitis (CP) was evaluated.

Carotid intima-media thickness in children and young adults with renal transplant: Internal carotid artery vs. common carotid artery.

Cardiovascular diseases are the main causes of morbidity and mortality following renal transplantation. Atherosclerotic structural changes, which can be detected by high-resolution B-mode ultrasonography, begin before clinical findings. However, little is known about the extent of these abnormalities in children after renal transplantation.

Palisade cartilage tympanoplasty for management of subtotal perforations: a comparison with the temporalis fascia technique.

Unlabelled: The use of cartilage as a grafting material has been advocated in cases at high risk for failure, such as subtotal perforations, adhesive processes, tympanosclerosis and residual defects after primary tympanoplasties. The cartilage palisade technique, in which the TM is fully reconstructed with palisade-shaped cartilage pieces, was first described by Heermann. Cartilage material has been criticized because of concerns regarding hearing results, however, large cartilage plates with thicknesses View Article and Find Full Text PDF

Influence of previous provisional cementation on the bond strength between two definitive resin-based luting and dentin bonding agents and human dentin.

This study evaluated the effect of two different types of provisional luting agents (RelyX Temp E, eugenol-based; RelyX Temp NE, eugenol-free) on the shear bond strengths between human dentin and two different resin-based luting systems (RelyXARC-Single Bond and Duo Link-One Step) after cementation with two different techniques (dual bonding and conventional technique). One hundred human molars were trimmed parallel to the original long axis, to expose flat dentin surfaces, and were divided into three groups. After related surface treatments for each specimen, the resin-based luting agent was applied in a silicone cylindrical mold (3.

Can preschool developmental screening identify children at risk for school problems?
