Treatment of Hemorrhoids: Rubber band ligation Or Sclerotherapy

We want to compare the effectiveness of sclerotherapy and rubberband ligation when it comes to symptoms. We will secondarily consider patient satisfaction, complications and recurrences. We hypothesize that both treatments are equally effective.

Is, in infertile women undergoing a basic fertility work-up, tubal flushing with oil-based contrast medium during hysterosalpingography (HSG) cost-effective compared to tubal flushing by hysterosalpingo-foam sonography (HyFoSy)? A randomized controlled trial.

The main objective of this study is to determine whether tubal flushing with oil-based contrast during HSG results into more pregnancies leading to live births when compared to tubal flushing with ExEm-foam during HyFoSy, and whether this approach…

An exploratory, multi-centre, two-part study to describe chronic induced urticaria characteristics and explore novel biomarkers with a multimodal patient profiling approach by comparing CIndU patients to chronic spontaneous urticaria patients and healthy volunteers

The objective of this study is to deep phenotype CIndU (subtype SD and ColdU) and detect novel biomarkers for diagnosis and treatment response as well as establish methodologies for (non-) invasive monitoring of treatment effects in chronic…
