Introduction: To reliably assess glomerular filtration is of vital importance if oral antidiabetics are used. We compared the CKD-EPI model, a clinically established calculation model to assess creatinine clearance (CreaClear) with specimens from 24-h urine.Method: Inpatients (university hospital) with diabetes mellitus received a 24-h urine collection (24hClear) or since 2013 calculated CreaClear using CKD-EPI-formula (EPI). From 2014 to 2015 values of ...

Background: Osteopetrosis is a rare chronic bone disease with high bone mineral densitiy due to impaired osteoclast activity or development. Genetic mutations result in severe infantile (autosomal recessive, incidence 1:200,000) and less severe adult forms (autosomal-dominant osteopetrosis/ADO). The incidence is estimated at 1:20,000 for noninfantile forms. In adults osteopetrosis is often asymptomatic with increased risk for bone fracture. Treatment is symptom-based (e.g. cal...

Background: Ectopic Cushing Syndrom (ECS) represents approximately 12% of all patients with Cushing´s disease. Either ACTH (5–10%), CRH or cortisol is produced uncontrolled from nonpituitary tissue. Half of ECS cases are neuroendocrine lung tumors [carcinoid tumors > small cell lung carcinoma (SCLC)], but ECS is clinically apparent only in 1–5% of SCLC cases. Clinical features vary according to extent and duration of exposure to ACTH/Cortisol excess and in...
