After widespread vaccination with COVID-19 vaccines, there have been worldwide reports on thrombosis, bleeding, and thrombocytopenia. Recently, a rare syndrome with a high mortality rate consisting of an unusual combination of thrombocytopenia and thrombosis, in particular cerebral venous sinus thrombosis, which clinically resembles heparin-induced thrombocytopenia, was reported following vaccination. Different statements and recommendations were developed regarding the definition, diagnosis, and treatment of these rare complications. We present here a protocol with recommendations, based on current evidence.

Chromosome abnormalities contribute to about 10% of cases of premature ovarian insufficiency. Most are associated with X chromosome. Fragile mental retardation 1 (FMR1) gene premutation has an estimated prevalence of 1% - 7% in sporadic cases and up to 13% in familial cases. Our aim was to describe the clinical characteristics, cytogenetic and FMR1 testing of a Portuguese population with premature ovarian insufficiency. ⋯ Our results underline the importance of genetic screening in premature ovarian insufficiency patients in both etiological study and genetic counselling.
