“…Renal length and cortical thickness have been studied extensively in animals and their parameters are well documented [ 8 , 9 ]. In humans, however, there have been only a few studies actually designed to measure these parameters in adults who do not have renal disease [ 10 , 11 ]. Unfortunately, in previous studies, some of the adults included had diseases such as diabetes and hypertension that could affect the kidneys [ 12 ].…”

Objective: To assess the normal sonographic values of renal length and cortical thickness in healthy adults and establish reference ranges in our population for comparison when examining renal disease. Subjects and Methods: Sonographic assessment of renal length and cortical thickness were performed from January 2006 to December 2011 in 252 healthy individuals who were self-referred to the El-Reshaid Renal Clinic in Kuwait. They were screened for the absence of renal abnormalities. Weight and height were measured, and body mass index (BMI) and body surface area calculated. Patients were divided into 5 age groups: 18-30, 31-40, 41-50, 51-60 and 61 -80 years, in order to generate reference graphs for renal length and cortical thickness. Results: The mean renal lengths for the right and left kidney were 10.68 ± 1.4 and 10.71 ± 1.0 cm, respectively (p = 0.56) without a significant change with age. The minimum cortical thickness was 0.6 cm. The renal length correlated with the weight of the patients (p < 0.01) and their BMI (p < 0.01) but not with their height. There was no difference in renal size or cortical thickness in patients older than 60 years despite an age-related decline in the glomerular filtration rate (p < 0.001). Conclusions: Renal length and cortical thickness did not vary significantly with age. Renal length correlated well with weight and BMI but not with height. Hence, establishing normal ranges of renal parameters is essential for comparison in situations where possible renal disease is being investigated.

Im Mittel findet sich ein Durchmesser der VCI von 14 mm und ein inspiratorischer Kollaps bei normaler Atmung von 35 % [19].…”

Dehydratation verstehen – wie viel Wasser braucht der ältere Mensch?

ZusammenfassungAls Exsikkose oder auch Dehydratation bezeichnet man ganz allgemein eine Symptomatik, die auf einen unphysiologisch niedrigen Wassergehalt des Organismus zurückzuführen ist. Aufgrund vieler im Alter häufigen Erkrankungen, aber auch vor dem Hintergrund des im Alter oft nachlassenden Durstgefühls, sind ältere Menschen besonders gefährdet, eine Dehydratation zu entwickeln. Die Symptomatik der Dehydratation geht nicht nur mit Schwäche und ggf. Verwirrtheit einher, sondern kann zu vielen Sekundärerkrankungen führen. Beispielsweise ist das Orthostasesyndrom, welches gehäuft zu Stürzen und Frakturen führt, meist durch eine Dehydratation bedingt. Die Diagnosestellung der Dehydratation ist gelegentlich schwierig, da keines der diagnostischen Zeichen über eine ausreichende Sensitivität und Spezifität verfügt. So kann die Diagnose meist nur aus der Gesamtschau des Patienten gestellt werden und durch eine erfolgreiche Therapie bestätigt werden. Für eine wirksame Prävention ist eine ausreichende tägliche Flüssigkeitszufuhr unumgänglich. Die 2018 veröffentlichte ESPEN-Leitlinie zur Klinischen Ernährung und Flüssigkeitsversorgung geriatrischer Patienten empfiehlt die Zufuhr von 1,6 und 2,0 Liter Getränken pro Tag für ältere Frauen und Männer.

“…However, the diagnostic value of conventional ultrasound is highly operator-dependent. Moreover, the documentation of ultrasound examinations is traditionally performed in poorly standardized two-dimensional images [2–4]. This neither permits a retrospective review of the entire examination nor allows a sufficient comparison with radiological imaging (computed tomography, CT; magnetic resonance imaging, MRI).…”

Evaluation of a novel tomographic ultrasound device for abdominal examinations

Conventional ultrasound (US) is the first-line imaging method for abdominal pathologies, but its diagnostic accuracy is operator-dependent, and data storage is usually limited to two-dimensional images. A novel tomographic US system (Curefab CS, Munich, Germany) processes imaging data combined with three-dimensional spatial information using a magnetic field tracking. This enables standardized image presentation in axial planes and a review of the entire examination. The applicability and diagnostic performance of this tomographic US approach was analyzed in an abdominal setting using conventional US as reference. Tomographic US data were successfully compiled in all subjects of a training cohort (20 healthy volunteers) and in 50 patients with abdominal lesions. Image quality (35% and 79% for training and patient cohort respectively) and completeness of organ visualization (45% and 44%) were frequently impaired in tomographic US compared to conventional US. Conventional and tomographic US showed good agreement for measurement of organ sizes in the training cohort (right liver lobe and both kidneys with a median deviation of 5%). In the patient cohort, tomographic US identified 57 of 74 hepatic or renal lesions detected by conventional ultrasound (sensitivity 77%). In conclusion, this study illustrates the diagnostic potential of abdominal tomographic US, but current significant limitations of the tomographic ultrasound device demand further technical improvements before this and comparable approaches can be implemented in clinical practice.
