Surgical management of urachal tumors: Can the umbilicus be sparred in localized disease?

Urachal adenocarcinoma represents the third most common histological type of non-urotelial bladder cancer. A very low incidence of this disease and the lack of prospective studies have led to a rich and heterogeneous treatment history. Currently, the standard of care for these patients is represented by partial cystectomy en bloc with resection of the urachal ligament and total omphalectomy.

Epitope-specific immunotherapy targeting CD4-positive T cells in coeliac disease: two randomised, double-blind, placebo-controlled phase 1 studies.

Background: A gluten-free diet is the only means to manage coeliac disease, a permanent immune intolerance to gluten. We developed a therapeutic vaccine, Nexvax2, designed to treat coeliac disease. Nexvax2 is an adjuvant-free mix of three peptides that include immunodominant epitopes for gluten-specific CD4-positive T cells.

Good Prognosis Went Badly: Fulminant Evolution of a 29-Year-Old Patient with Verrucous Carcinoma of the Cervix.

Verrucous carcinoma (VC) is a very rare variant of squamous cell carcinoma of the cervix, difficult to point out in histology because of its benign appearance. We present the case of a 29-year-old woman with a locally advanced cervical VC who underwent radiotherapy followed by radical hysterectomy. After local relapse and despite pelvic exenteration, her condition deteriorated.

Celiac Disease Phenotype in Clinically Diagnosed Romanian Adults and Children.

Background: Once considered a disease of childhood, celiac disease (CD) is now seen quite frequently in adults also, but with different and various clinical presentation. Little data is currently available about pediatric and adult CD features in Romanian patients.

Methods: 38 newly-diagnosed CD patients (17 adults and 21 children) were recruited for this study.

Prevalence and predictors of anaemia in Romanian infants 6-23 months old.

Background: Anaemia is a public health problem that can lead to a variety of detrimental effects on physical and neurodevelopment in young children. The present study explored the epidemiology of anaemia among infants in Romania, identified risk factors and created a model for predicting it.

Methods: Data from 1532 infants aged 6-24 months were selected from a larger nationally representative cross-sectional survey.

Polycomb Repressive Complex 2 Enacts Wnt Signaling in Intestinal Homeostasis and Contributes to the Instigation of Stemness in Diseases Entailing Epithelial Hyperplasia or Neoplasia.

Canonical Wnt/β-catenin signaling regulates the homeostasis of intestinal epithelium by controlling the balance between intestinal stem cell self-renewal and differentiation but epigenetic mechanisms enacting the process are not known. We hypothesized that epigenetic regulator, Polycomb Repressive Complex-2 (PRC2), is involved in Wnt-mediated epithelial homeostasis on the crypt-villus axis and aberrancies therein are implicated both in celiac disease and in intestinal malignancies. We found that PRC2 establishes repressive crypt and villus specific trimethylation of histone H3 lysine 27 (H3K27me3) signature on genes responsible for, for example, nutrient transport and cell killing in crypts and, for example, proliferation and differentiation in mature villi, suggesting that PRC2 facilitates the Wnt-governed intestinal homeostasis.

Velamentous insertion of umbilical cord with vasa praevia: case series and literature review.

A velamentous umbilical cord is characterized by membranous umbilical vessels at the placental insertion site that are prone to compression and rupture, especially when they are located in the membranes covering the cervical os (vasa praevia). The velamentous insertion of the umbilical cord, with a reported incidence of 1% in singleton pregnancies and 15% in monochorionic twin gestations, has been associated with obstetric complications: fetal growth restriction, prematurity, congenital anomalies, low Apgar scores, fetal bleeding with acute fetal distress and placental retention. The pathogenesis is unknown, but the trophotropism theory is the most common and supported by the association of velamentous cord insertion and placenta praevia.

Endometrial Adenocarcinoma Presenting as Hematometra with Underlying Thickened Endometrial Lining in a Postmenopausal Woman - A Case Report.

Background: Although most postmenopausal women diagnosed with endometrial cancer usually present with vaginal bleeding, when complete cervical stenosis is present, this sign may be missing. In these cases, the patient usually complaints for pelvic or abdominal pain while the transvaginal ultrasonography might reveal the presence of an intrauterine fluid collection in association with a thickened endometrial lining.

Case Report: We present the case of a 65-year-old patient who presented with association of pelvic pain, enlarged uterine cavity with an underlying hematometra and an irregular, thickened endometrium who was submitted to surgery for total histerectomy, bilateral adnexectomy, pelvic and para-aortic lymph node dissection.

Regression Rates Following the Treatment of Aggressive Posterior Retinopathy of Prematurity with Bevacizumab Versus Laser: 8-Year Retrospective Analysis.

BACKGROUND Retinopathy is a serious complication related to prematurity and a leading cause of childhood blindness. The aggressive posterior form of retinopathy of prematurity (APROP) has a worse anatomical and functional outcome following laser therapy, as compared with the classic form of the disease. The main outcome measures are the APROP regression rate, structural outcomes, and complications associated with intravitreal bevacizumab (IVB) versus laser photocoagulation in APROP.

A Prospective Study on the Usefulness of Duodenal Bulb Biopsies in Celiac Disease Diagnosis in Children: Urging Caution.

Objectives: Several recent celiac disease guidelines recommend the acquisition of duodenal bulb biopsies for diagnostics. This is in conflict with previously reported evidence and routine practice from the 1960s onward. We reopened the issue in a prospective multicenter study and used morphometric variables in evaluating the usefulness of bulb biopsies in children.

Diagnostic yield of endoscopic markers for celiac disease.

Rationale: In the setting of open access endoscopy, the recognition of suggestive endoscopic features in the duodenum can select patients with probability of celiac disease (CD). This could add to the current efforts to increase the diagnostic rate of this disease.

Aim: The aim of this study was to evaluate the diagnostic accuracy of these markers for CD in an adult population undergoing endoscopy, without a prior serological testing.

A novel common large genomic deletion and two new missense mutations identified in the Romanian phenylketonuria population.

The mutation spectrum for the phenylalanine hydroxylase (PAH) gene was investigated in a cohort of 84 hyperphenylalaninemia (HPA) patients from Romania identified through newborn screening or neurometabolic investigations. Differential diagnosis identified 81 patients with classic PAH deficiency while 3 had tetrahydropterin-cofactor deficiency and/or remained uncertain due to insufficient specimen. PAH-genetic analysis included a combination of Sanger sequencing of exons and exon–intron boundaries, MLPA and NGS with genomic DNA, and cDNA analysis from immortalized lymphoblasts.
