Increased CD3, CD8, or FoxP3 T Lymphocyte Infiltrations Are Associated with the Pathogenesis of Colorectal Cancer but Not with the Overall Survival of Patients.

Tumor-infiltrating lymphocytes include heterogeneous populations of T lymphocytes that play crucial roles in the tumor immune response; importantly, their presence in the tumor tissue may predict clinical outcomes. Therefore, we herein studied the prognostic significance of the presence and location of CD3, CD8, and FoxP3 T lymphocytes in colorectal cancer samples. In the intratumor analysis, our data did not reveal any association between lymphocyte infiltrations with clinical or pathological data.

Recurrent fetal triploidy: is there a genetic cause?

Triploidy is currently understood as a sporadic genetic disorder, with no recognisable risk of recurrence nor identifiable risk factors. In cases of triploidy, chances of thriving through the second trimester of fetal development are very slim, with most of these pregnancies ending as early miscarriage. We report a case of repeated triploid pregnancies in the same woman, from different fathers, achieving the second trimester of pregnancy; elective termination was decided in both cases, after an amniocentesis revealing a triploid karyotype.

Prenatal diagnosis of Bardet-Biedl syndrome: a multidisciplinary approach.

Bardet-Biedl syndrome (BBS) is a rare ciliopathic human genetic disorder with mainly an autosomal recessive inheritance. BBS phenotype develops over the years and diagnosis is usually made in late childhood or early adulthood. Prenatal diagnosis is rare in the absence of family history or consanguinity.

Prenatal diagnosis of fibular aplasia-tibial campomelia-oligosyndactyly syndrome: Two case reports and review of the literature.

Fibular aplasia-tibial campomelia-oligosyndactyly also known as FATCO syndrome is a rare condition characterized by fibular aplasia, shortening and anterior bowing of the lower limb at the tibia with overlying soft tissue dimpling and oligosyndactyly. Its etiology is currently unknown, but there is a male predominance. There are less than 30 cases reported in the literature but only three with prenatal diagnosis.

Prenatal diagnosis of frontal encephalocele.

Encephalocele is a rare congenital form of neural tube defect characterized by a protrusion of the meninges and cerebral tissue through a skull defect. These defects are classified according to their location: frontal, parietal and occipital, the last one being the most common form of presentation. The prognosis is related to the anatomical site, the volume of the neural contents and the presence of coexisting abnormalities.

Dichorionic twins discordant for body-stalk anomaly: a management challenge.

Body-stalk anomaly is a sporadic and rare maldevelopment disorder characterised by large abdominal wall defect, spinal deformity and rudimentary umbilical cord. It is considered a lethal condition as there are only few reports of survival but there was at least one case of long-term survival after neonatal surgery.Differential diagnosis includes isolated omphalocele or gastroschisis, short umbilical cord, amniotic band, limb body-wall complex and other polymalformative syndromes.

DOK7 myasthenic syndrome with subacute adult onset during pregnancy and partial response to fluoxetine.

DOK7 congenital myasthenic syndrome (DOK7-CMS) generally presents early in life and is treated with salbutamol or ephedrine. This report describes an atypical case of a 39-year-old woman who presented with proximal upper limb weakness in the third trimester of pregnancy and was initially diagnosed with seronegative myasthenia gravis. Dramatic clinical worsening under pyridostigmine and further inefficacy of steroids, intravenous human immunoglobulin (IVIG) and plasma exchange (PLEX) led to the presumptive diagnosis of a CMS.

V280G Mutation, Potential Role in Imatinib Resistance: First Case Report.

Introduction: The identification of as the defining leukemogenic event in chronic myeloid leukemia (CML) and the introduction of tyrosine kinase inhibitors in 2001 have revolutionized disease management, leading to a reduction in mortality rates and accordingly an increase in the estimated prevalence of CML.

Case Report: Based on medical records and clinical follow-up, the authors present the case of a Philadelphia chromosome-positive CML patient who developed resistance to imatinib. Quantitative reverse transcription-polymerase chain reaction testing revealed a V280G mutation.

Prenatal ultrasound and postmortem histologic evaluation of tooth germs: an observational, transversal study.

Introduction: Hypodontia is the most frequent developmental anomaly of the orofacial complex, and its detection in prenatal ultrasound may indicate the presence of congenital malformations, genetic syndromes and chromosomal abnormalities. To date, only a few studies have evaluated the histological relationship of human tooth germs identified by two-dimensional (2D) ultrasonography. In order to analyze whether two-dimensional ultrasonography of tooth germs may be successfully used for identifying genetic syndromes, prenatal ultrasound images of fetal tooth germs obtained from a Portuguese population sample were compared with histological images obtained from fetal autopsies.
