BACKGROUND: Advancing knowledge in molecular pathogenesis of hepatocellular carcinoma (HCC) opens up new horizons in the diagnostic, prognostic and therapeutic perspectives. Assessing the expression of molecular targets prior to definitive treatment is gaining importance in clinical practice. In this study, we investigated the variation in expression pattern of stemness markers in synchronous multi-focal HCC. METHODS: In the first cohort, 21 liver explants with multi-focal HCC were examined for expression of stemness markers EpCAM, Sox9 and CK19 by immunohistochemistry (IHC)...

BACKGROUND: Conservative wait-and-scan management for vestibular schwannomas (VSs) is an important treatment option, but its role is unclear because of discordance between tumor growth and hearing outcomes. METHODS: The present study was a retrospective analysis of 97 patients with sporadic VSs who were followed-up without treatment between 2003 and 2012. Tumor volume was measured by three-dimensional volumetry at each follow-up visit. The median follow-up duration was 47 months (range, 13-122 months)...

Fetal malformations are more frequent in twins than in singletons. The aim of our study was to define the influence of a malformed twin on di-chorionic pregnancy outcomes. We performed a retrospective cohort study of di-chorionic pregnancies delivered between 2000 and 2015. Exclusion criteria were: both twins affected by fetal malformations, double intra-uterine fetal death in pregnancies without fetal malformation, selective feticide and therapeutic pregnancy termination. We compared maternal and fetal outcomes of di-chorionic pregnancies not complicated by fetal malformations with pregnancies affected by a single malformed fetus with conservative management...

Massive perivillous fibrinoid deposition (MFD) and maternal floor infarction (MFI) are lesions of unknown etiology associated with poor perinatal outcomes, including fetal intrauterine growth restriction and neurodevelopmental injury, high risks of pregnancy loss, and recurrence in subsequent gestations. MFI comprises massive intervillous fibrinoid deposition concentrated at the maternal floor. MFD is a similar lesion but is diffuse within the parenchyma. MFD/MFI lesions represent a spectrum of severity of cloak-like perivillous fibrinoid deposition, and there is mounting evidence that, often, they represent sequelae of immune-mediated phenomena and/or an imbalance in factors that normally maintain the fluidity of blood in the maternal space...

BACKGROUND: Solitary fibrous tumor is an uncommon soft tissue neoplasm with intermediate biological behavior, which rarely metastasizes. Malignant solitary fibrous tumor, although not clearly defined, is rarely described in the prostate. The present case is characterized by some peculiarities if compared with previously reported cases of prostatic malignant solitary fibrous tumor. Firstly, it does not show a homogeneous morphology: part of the neoplasm (about 50%) showed the features of a conventional solitary fibrous tumor, while the remaining part showed the features of a malignant solitary fibrous tumor...

OBJECTIVE: Exposure to adverse social environments has been associated with psychotic and depressive symptoms in adolescence in cross-sectional studies, but the longitudinal relation is unclear. This study examined whether longitudinal trajectories of exposure to adverse social environments across childhood are associated with psychotic experiences and depressive symptoms in adolescence. METHOD: Data on participants from the Avon Longitudinal Study of Parents and Children (ALSPAC) were used to estimate longitudinal trajectories of childhood exposure to neighborhood cohesion (NC), discord (ND), and stress (NS) using latent class growth modeling...

Molecular tests to detect the presence of Mycobacterium tuberculosis and genetic polymorphisms in the rpoB gene conferring resistance to rifampicin (RMP) have become integral parts of tuberculosis diagnostics worldwide. These assays are often performed sequentially or in parallel to phenotypic drug susceptibility testing. Discordances between molecular and phenotypic tests invariably occur. Root causes range from pre-, post- and analytic errors to co-existence of non-tuberculous mycobacteria, silent mutations, mutations outside the 81 base-pair RMP resistance-determining region, non-canonical mutations conferring increased minimal inhibitory concentrations below the critical concentration in some phenotypic drug susceptibility tests, and heteroresistance...

Plant morphogenesis requires differential and often asymmetric growth. A key role in controlling anisotropic expansion of individual cells is played by the cortical microtubule array. Although highly organized, the array can nevertheless rapidly change in response to internal and external cues. Experiments have identified the microtubule-severing enzyme katanin as a central player in controlling the organizational state of the array. Katanin action is required both for normal alignment and the adaptation of array orientation to mechanical, environmental, and developmental stimuli...

BACKGROUND: Invasive lobular carcinoma (ILC) is characterized by an infiltrative discohesive growth pattern, making it difficult to accurately assess both clinically and by imaging studies. Despite favourable biological characteristics, challenges remain in the surgical treatment of ILC. We aimed to evaluate radiology/histology concordance and identify histological and biological parameters on core biopsies that may predict final tumour histology and guide surgical treatment decisions...

AIM: Immunohistochemistry (IHC) and fluorescence in situ hybridization (FISH) are common methods for assessment of human epidermal growth factor receptor 2 (HER2) in breast cancer. MATERIALS AND METHODS: In a cohort of 498 consecutive patients with breast cancer, we examined concordance between IHC and FISH for HER2 on tissue microarray (TMA) sections. In a subset of 116 specimens, we examined HER2 concordance from the block used for diagnostics and a randomly-chosen additional block (a proxy of the core biopsy)...

AIM: This study investigated the feasibility and safety of fetoscopic laser photocoagulation (FLP) for amniotic fluid discordance (AFD) bordering on twin-twin transfusion syndrome (TTTS) with an absent or reverse end-diastolic velocity (AREDV) in the umbilical artery (UA), and evaluated the perinatal and long-term outcomes. METHODS: A prospective intervention study was performed between 20 + 0 and 25 + 6 weeks of gestation (UMIN000004165). AFD bordering on TTTS was defined as maximum vertical pocket (MVP) of amniotic fluid in one twin's sac ≤3 cm and amniotic fluid MVP in the other twin's sac ≥7 cm excluding TTTS...

A 200∼240 kb SH2B1-containing deletion region on 16p11.2 is associated with early-onset obesity and developmental delay. Here, we describe monozygotic twin brothers with discordant clinical presentations. Intrauterine fetal growth restriction was present in both twins. Additionally, twin A exhibited coarctation of aorta, left ventricular noncompaction, atrial septal defect, pericardial effusion, left hydronephrosis, and moderate developmental delay, whereas twin B exhibited single umbilical artery. Chromosome microarray analysis was performed on both twins and their parents...

PURPOSE: It is well-known that tumor phenotype may change during the progression of breast cancer (BC). The purpose in this study was to compare the discordance in estrogen receptor (ER), progesterone receptor (PgR) and human epidermal growth factor receptor 2 (HER2) between primary and recurrent/metastatic lesions (RML) and also to evaluate the prognostic significance of change in tumor phenotype on survival in patients with metastatic BC. METHODS: The medical records of 6638 patients with BC from two breast centers treated between 1992 and 2015 were retrospectively analyzed...

BACKGROUND: Discordance in the receptor status between primary breast carcinomas (PBC) and corresponding metastasis is well documented. Interrogation of the receptor status of metastatic breast carcinoma (MBC) in cytology material is common practice; however, its utility has not been thoroughly validated. We studied patients with MBC, and evaluated the concordance rates of estrogen receptor (ER), progesterone receptor (PR) and human epidermal growth factor receptor 2 (HER2) between PBC surgical specimens and corresponding MBC cell blocks (CBs)...

Umbilical cord entanglement is the leading cause of fetal mortality in monoamniotic twin pregnancies and a pseudo monoamniotic environment. Published methods for detecting this complication include color Doppler and pulsed Doppler sonography; however, no method provides an absolute diagnosis. In this case, we report the diagnosis of umbilical cord entanglement using dual-gate Doppler imaging. A 35-year-old woman was referred to our hospital at 28 weeks of gestation for prenatal management because of diagnosis of a monochorionic diamniotic twin pregnancy with spontaneous septostomy of the dividing membranes...

Osteoarthritis (OA) is a common joint disease characterised by the focal loss of the protective cartilage layer at the ends of the bones. It is painful, disabling, multifactorial and polygenic. The growth differentiation factor 5 gene GDF5 was one of the first reported OA susceptibility signals that showed consistent association to OA, with the transcript single nucleotide polymorphism (SNP) rs143383 demonstrating association in Asians and Europeans. The functional effect of the signal is reduced expression of the gene...
