Male reproductive disorders are common and there is evidence for increasing incidence over recent decades. These disorders may present at birth (hypospadias and cryptorchidism) or in adulthood (infertility, testicular cancer) and can arise as a result of underlying genetic abnormalities or following environmental (e.g. phthalates) and pharmaceutical (e.g. analgesics, chemotherapy) exposures that impact fetal, neonatal of prepubertal testicular development. Understanding the re...

Background: MicroRNAs are small non-coding RNAs that regulate gene expression and play major roles in many physiological and pathological processes.Objective and hypotheses: Determine whether changes in microRNA expression contribute to β-cell dysfunction and/or loss and favor the development of diabetes.Method: Analysis of the changes in microRNA expression occurring in pancreatic islets of diabetes animal models and assessme...

Histomorphometric evaluation of transiliac bone samples represents a standardized tool for studying bone metabolism, yielding information on bone both static and dynamic parameters on bone formation and static resorption parameters. Beyond these routine evaluations, the identical bone biopsy sample can be further used to assess submicroscopic tissue characteristics of the bone matrix. At the material level, bone matrix can be considered as a mineral/organic matrix composite wh...

One potential solution in improving Type 1 Diabetes (T1D) management is the use of technology, providing additional opportunities to support management, maintain and improve communication and engagement with healthcare services. Patients use Internet to search and interact with a community of patients with similar problems; to share clinical information; and to provide and receive support. Facebook with over 2.1 billion active monthly users worldwide is important source of inf...

Background: Dopa-responsive dystonia is a genetic disease that rarely reported in domestic and foreign. Its clinical characteristics is so complex and diverse that it is easy to lead to misdiagnosis and delayed treatment. However, early diagnosis and timely and appropriate treatment can completely improve symptoms. Fortunately, now we can take advantage of gene sequencing to diagnose this rare disease.Objective and hypotheses: Understand the research pro...

Background: Hot thyroid nodules are uncommon in children and adolescents. Hyperfunctioning adenoma do not always produce hyperthyroidism, but can precede the apparition of a truly toxic adenoma. Autonomous adenoma can be associated with mutations of TSH-R and some mutations of GNAS.Patients: Patient 1 presented mild clinical hyperthyroidism. Patients 2 and 3 were asymptomatic and had clinical euthyroidism. Examination revealed a unique isolated thyroid n...

The McCune–Albright syndrome can be a disease of striking complexity, the management of which can be challenging. However, an understanding of the physiologic consequences of the underlying molecular and developmental biology makes the evaluation and treatment of this disease relatively straightforward. MAS arises from activating mutations in the ubiquitously expressed cAMP-signaling protein, Gsα. The mutations occur very early in development, prior to gas...

Background: In pediatric patients multiple pituitary hormone deficiency (MPHD) can be caused by mutations in pituitary-specific transcription factors. Among those, mutations in PROP1 gene account for ~50% of genetically determined cases of CPHD. Regarding morphology, the anterior pituitary can be normal, hypo-/aplastic or enlarged.Results: We present two unrelated patients referred for evaluation of growth retardation. Both had profound growth retardatio...

Science was formerly an integral part of philosophy, but these two broad disciplines have gradually grown apart and are now typically viewed as completely different endeavors. In this talk, I will argue in favor of a renaissance in the integration of science and philosophy. I will argue first that philosophy can fruitfully contribute to science. I will take the example of stem cells in various contexts (homeostasis, regeneration and regenerative medicine, cancer) to illustrate...

Gynecologic anomalies, including uterine agenesis and ovarian dysgenesis, are reported in clinical practice of reproductive endocrinology. They are some of several differential diagnoses in adolescent females with primary amenorrhea and delayed puberty. Primary ovarian insufficiency can be determined by conducting sex hormone tests to evaluate the hypothalamic-pituitary-ovarian axis, but accurate confirmation of Mullerian agenesis can be extremely challenging by image modaliti...
