Paget-Schroetter syndrome: the importance of early detection and effective surgical intervention.

Paget-Schroetter syndrome (PSS) is relatively rare condition of thoracic outlet syndrome characterized by thrombosis or blood clot formation in the subclavian vein. Due to the non-specific symptoms and low incidence rate, PSS is frequently missed by medical professionals, and as such it often leads to wrong diagnosis and untreated patients. We present the case of a 30-year-old CrossFit trainer who developed a thrombosis of the subclavian vein.

Disease progression in Parkinson subtypes: the PPMI dataset.

Introduction: Discrete patterns of progression have been suggested for patients with Parkinson disease and presenting tremor dominant (TD) or postural instability gait disorders (PIGD). However, longitudinal prospective assessments need to take into consideration the variability in clinical manifestations and the evidence that only 40% of initially classified PIGD remain in this subtype at subsequent visits.

Methods: We analyzed clinical progression of PIGD compared to TD using longitudinal clinical data from the PPMI.

Possibilities of association of azoospermia and oligospermia with some HLA system antigens.

Modern knowledge of the HLA system structure and its role in the organism supports the statement that the presence of HLA antigens in a person increases his/her predisposition to some diseases. Association of HLA antigens with some diseases has already been confirmed by many authors.
