[Do We Need more Volunteer Work in Medicine? Project Examples from Trauma Surgery].

The nursing shortage, legal requirements, and funding deficits have led to increasingly poor patient care in German hospitals.Volunteer patient companions offer support by conversing with and caring for patients. This can work to relieve hospital staff while diminishing patients' fears/worries.

Community Service as Patients' Tutor to Avoid Delirium.

Background: Today, nearly two thirds of inpatients in trauma surgery hospitals are over 70 years old and at significant risk for comorbidities. These patients frequently suffer delirium. Delirium occurs in 15 - 30% of these trauma patients and increases the risk of mortality in up to 15 - 25% of cases.

Surgical and Non-surgical Treatment of Vertebral Fractures in Elderly.

Demographic development in Germany has led to an aging of the population. Particularly for these patients, osteoporosis-induced vertebral fractures represent a significant decrease in quality of life and level of activity. According to current guidelines, the initial treatment of stable osteoporotic vertebral fractures is conservative management with analgesic, anti-osteoporotic, physical therapy, and orthotic measures as first line options.

[Foreign Material-Free Anterior Cruciate Ligament Repair with Hamstring Graft, Felmet Technique].

Rupture of the anterior cruciate ligament (ACL) is a common sports injury. Shear forces can damage the articular cartilage and lead to early osteoarthritis. Ligamentary stabilisation of the knee is necessary.

[Venous Paravasation After Augmentation of Pedicle Screws - An Underestimated Risk].

Cement-augmented pedicle screws can increase the stability of fixators for unstable vertebral fractures in the elderly. Fixators can be inserted quickly and with minimally invasive techniques, reducing surgical risks. From March 2012 until July 2014, we treated 40 patients with percutaneous augmented fixators for unstable vertebral fractures.

Hemiprosthesis for Femoral Neck Fractures in the Elderly: A Retrospective Study of 319 Patients.

Background: In geriatric patients with Pauwels types II and III femoral neck fractures, hemiprosthesis is the therapy of choice.

Objectives: This study was conducted to analyze the results after cemented hemiprosthesis placement, the first year after surgery.

Patients And Methods: This retrospective study was conducted on 319 patients over 70 years with displaced femoral neck fractures treated surgically at our hospital from 2007 to 2012.

Cyclic AMP increases cytoplasmic free calcium in renin-secreting cells from rat kidney.

The renin-secreting juxtaglomerular cells (JGC) in the media of the afferent arteriole at the vessel pole are the major source of circulating renin. The control of renin secretion is complex with increases in cAMP being the major stimulus and increases in intracellular free Ca2+ concentration ([Ca2+]i) being inhibitory. We measured [Ca2+]i in the afferent arteriole from mostly JGC.
