Primary hyperparathyroidism is a heterogeneous clinical entity. In the clinical setting, the diagnosis and management of familial isolated hyperparathyroidism (FIHP) and other familial hyperparathyroidism (FHPT) forms continue to rely on clinical, laboratory, and histological findings, with careful examination of the family. In this article, we report a case series of FIHP in a four-generation Greek family, with no identifiable gene mutations. Clinical approach and long-term follow-up are discussed and a narrative review of the genetic basis of this entity has been performed.
Propylthiouracil (PTU), carbimazole (CMZ) and methimazole (MMI) are the most common drugs used today in cases of adolescent thyrotoxicosis. Skepticism has been growing regarding the use of PTU in childhood and its association with severe liver failure. The aim of this review is to present all the recent data regarding pathogenesis of PTU hepatotoxicity in children and adolescents. Specifically, reactive drug metabolites and increased oxidative stress can directly activate inflammatory and immunological pathways. Drugs are not only immunogenic because of their chemical reactivity but also because they may bind through electrostatic forces to available T-cell receptors. Redox modulation is also a key regulatory strategy in the adaptive immune system. Subtle changes in the extracellular redox status may cause profound functional changes in redox-sensitive proteins. Genetic factors that affect drug biotransformation could also be implicated in this mechanistic model of PTU-related hepatotoxicity. Further studies are needed to fully understand the pathophysiology of PTU-induced liver damage.

A new group of hypoglycemic drugs has been used to treat diabetes type 2. This group is active sodium glucose co-transporter (SGLT2) or SGLT2 inhibitors. It has been shown that besides the treatment of diabetes, this drug class is responsible for the mildness of the cardiovascular events shown in patients with diabetes type 2. However, there is an intriguing question regarding the range of SGLT2 inhibitors and if there is a difference between them or if there is a class effect among their results. EMPA-REG OUTCOME trial and the CVD-study are used to answer this question. Additional information from the DECLARE-TIMI 58 and Dapa-HF trials are studied.
Background:
To report the cardiovascular and renal effects of incretin-based therapies.
Method:
The studies of clinical trials on incretin-based therapy published in medical journals from years 2010 to 2017 were comprehensively searched using MEDLINE and EMBASE with no language restriction. The studies were reviewed and the cardiovascular and renal risks reported were recorded.
Results:
Incretin-based therapeutics represent novel and promising anti-diabetes drugs, the direct cardiovascular actions of which may translate into demonstrable clinical benefits on cardiovascular outcomes. Furthermore incretin-based therapies do not adversely affect renal function.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
