Rückfu?valgus

The clinical finding of flatfoot is characterized by a flattening of the medial longitudinal arch and valgus deformity of the hindfoot. The differential diagnosis of flatfoot is the physiological, flexible, contracted flatfoot, which occurs as a congenital or acquired deformity. Congenital flatfoot deformity requires early intensive therapy, while a flexible flatfoot in children has a good prognosis and conservative treatment usually leads to a stable and sufficient load-bearing foot. Severe flatfoot in children can be corrected successfully by simple, minimally invasive procedures. In adults with symptomatic flatfoot, which usually occurs due to an insufficiency of the tendon of the tibialis posterior, conservative therapy with insoles, shoe modifications and physiotherapeutic measures can lead to significant improvement, otherwise surgical correction is recommended. Early, stage-appropriate therapy helps to prevent an impending decompensation of the hindfoot.     

MR-Kolonographie: Technik, Indikationen und Befunde

Magnetic resonance imaging (MRI) has evolved as a powerful tool that has been applied more and more in recent years for the assessment of gastrointestinal structures, owing to its unsurpassed soft tissue contrast, lack of radiation exposure, and implementation of fast scanning techniques. As a virtual endoscopic technique, MR colography (MRC) makes it possible to image inflammatory processes and tumor disease of the large intestine with a high degree of accuracy. In this article we describe current techniques and applications of MRC and give an overview of clinical studies comparing MRC with other diagnostic procedures.

Innovative Sonographie beim Prostatakarzinom

Zusammenfassung Zur Früherkennung und Stadieneinteilung des Prostatakarzinoms wird heutzutage fast ausschließlich die sog. systematische Mehrfachbiopsie eingesetzt. Hierbei tritt das bildgebende Verfahren – der transrektale Ultraschall – als Diagnostikum mehr und mehr in den Hintergrund und dient fast ausschließlich zur Führung der Biopsienadel in spezifische anatomische Regionen. Doch selbst bei multiplen systematischen Biopsien wird eine hohe Zahl klinisch signifikanter Karzinome übersehen. Diese Tatsache hat zu einer drastischen Steigerung der Anzahl von Gewebeproben geführt. So finden sich Zentren, in denen 6, 10, 12, ja bis zu 143 Gewebeproben in einer Sitzung entnommen werden. Diese immer invasivere heterogene Vorgehensweise bestätigt den Bedarf an Verbesserung in der Ultraschalldiagnostik. Neue und innovative bildgebende Verfahren in der Prostatasonographie werden vorgestellt mit dem Ziel, die diagnostische Aussagekraft bei Erstdiagnose sowie in der Stadienvorhersage zu verbessern. Eine verbesserte Bildgebung bei Diagnosestellung und in der Stadieneinteilung würde zu einer erheblichen Verbesserung bei den Therapieentscheidungen führen.Dieser Beitrag ist dem kürzlich verstorbenen Pathologen J. E. McNeal gewidmet, der die zonale Anatomie der Prostata erstbeschrieben hat.     

Zum Kenntnisstand von Patienten über die Aufgaben der Anästhesiologie

The anaesthesiologist's competence in anaesthesia, intensive care medicine, pain therapy and emergency medicine is accepted throughout the medical society. Nevertheless, during the last decades patient surveys demonstrated a considerable lack of information of the responsibility of our work. By continuous education and information anaesthesiologists have aimed to improve the information and decision-making process for the patient. This multicentre trial was designed to investigate the current public view on our profession in seven German hospitals. In-hospital patients were asked to fill out a standardised questionnaire prior to the anaesthesia premedication visit and a total of 692 questionnaires (77%) were analysed. Results demonstrated an increased level of knowledge for anaesthesia (>95%), intensive care medicine (74%), and pain therapy (50% acute pain; 32% severe pain). In the case of emergency medicine (10%) the in-hospital and out-of-hospital responsibilities were not clear among patients. We conclude that the continuous distribution of information in recent years has contributed to improving patients' knowledge on interdisciplinary responsibilities. Future efforts should focus on the gaps in patient's knowledge to allow the patient to ask the right questions necessary for decision-making.     

Einsatz von gecufften Endotrachealtuben bei Kindern in der Notfall- und Rettungsmedizin

Cuffed pediatric tracheal tubes are increasingly used in pediatric anesthesia and pediatric intensive care for infants and small children. High chance to select a correct-fitting tube and reliable sealing of the trachea without the use of an oversized uncuffed tube are the most import advantages of using cuffed tubes for infants and small children in emergency situations. If cuffed tubes in pediatric emergency are used a well-designed tube with a correctly placed high volume-low pressure and an adequate intubation depth mark and the presence of a printed chart with recommendations for age-related tube size selection should be available. Confirmation of an air leak around the tracheal tube after intubation with the cuff not inflated, cuff inflation by cuff pressure monitoring and limitation of cuff pressure at 20 cmH₂O allows the safe use of cuffed tracheal tubes in infants and children. In case of lack of good pediatric cuffed tubes, lack of a chart with recommendations for age-related tube size selection and lack of a cuff pressure manometer, cuffed pediatric tubes should not be used in infants and children in the emergency setting.     

Autologe Chondrozytentransplantation am oberen Sprunggelenk

Ankle sprains are one the most common injuries of the lower limb. Fractures, ligamentous lesions, and cartilaginous damage are often associated. Nevertheless the injury is often misjudged and concomitant chondral lesions are assessed late. In the case of a symptomatic osteocartilaginous lesion of the talus, which can be illustrated by MRI or X-ray, operative intervention is indicated. Methods such as microfracturing, mosaicplasty, and autologous chondrocyte transplantation (ACT) are in clinical use. The latter is well known and being established as the treatment of choice for large cartilage defects in the knee. Due to the good results in the knee and the technological improvements (three-dimensional tissue constructs seeded with autologous chondrocytes) this method is being increasingly applied for cartilage lesions of the talus. In contrast to the mosaicplasty donor site morbidity is low and the size of the defect is not a limiting factor. The current studies about ACT of the talus show a stable repair of the defect with mostly hyaline-like cartilage and high patient satisfaction. Therefore, the procedure can be recommended for lesions >1 cm². Concomitant treatment of posttraumatic deformities (malalignment), ligamentous instabilities, and especially the reconstruction of bony defects are compulsory.     

Sinnvolle bildgebende Diagnostik des lokal fortgeschrittenen Prostatakarzinoms

Prostate cancer is one of the principal medical problems facing the male population in developed countries with an increasing need for sophisticated imaging techniques and risk-adapted treatment options. This article presents an overview of the current imaging procedures in the diagnosis of locally advanced prostate cancer. Apart from conventional gray-scale transrectal ultrasound (TRUS) as the most frequently used primary imaging modality we describe computed tomography (CT), magnetic resonance imaging (MRI), and positron emission tomography (PET). CT and MRI not only allow assessment of prostate anatomy but also a specific evaluation of the pelvic region. Color-coded and contrast-enhanced ultrasound, real-time elastography, dynamic contrast enhancement in MR imaging, diffusion imaging, and MR spectroscopy may lead to a clinically relevant improvement in the diagnosis of prostate cancer. While bone scintigraphy with (99m)Tc-bisphosphonates is still the method of choice in the evaluation of bone metastasis, whole-body MRI and PET using (18)F-NaF, (18)F-FDG, (11)C-choline, (11)C-acetate, and (18)F-choline as tracers achieve higher sensitivities.     

Intraoperative Echokardiographie

Since the introduction of intraoperative echocardiography into clinical practice in the 1970’s its use and utility in the perioperative period has become increasingly more evident. Especially in patients undergoing cardiac surgical procedures intraoperative echocardiography has gained great diagnostic importance. Intraoperative transesophageal echocardiography (TEE) and epiaortic ultrasound are two important and complementing diagnostic modalities in this patient population. The clinical information obtained with intraoperative TEE in certain cases might have a direct impact on surgical decision-making and therefore may positively influence patient outcome. In patients undergoing non-cardiac surgical procedures, TEE can be a valuable tool in high-risk patients, in patients experiencing hemodynamic instability or in those suffering intraoperative cardiac arrest. Intraoperative TEE might allow a primary diagnosis of the underlying etiology and facilitate the institution of further therapeutic interventions. In addition TEE can be performed during ongoing cardiopulmonary resuscitation and does not interfere with patient management. This review introduces the clinician to the current evidence of the impact of intraoperative echocardiography on intraoperative surgical decisions during surgical procedures. It helps the clinician to identify indications and realize the potential applications of intraoperative echocardiography.     

Verteilungsplanung von Verletzten beim MANV oder Katastrophenfall

Relevant changes have occurred in disaster management in Germany due to legal alterations and the introduction of the diagnosis-related groups (DRG) system. This has resulted in a reduction in bed capacities and an increase in bed utilization. In addition to the preclinical deployment strategy the provisional aspects of disaster medicine with the problem of the emergency service/hospital interface will be described. A suggestion for a solution for optimization of patient allocation in mass disasters or catastrophes will be demonstrated with the catastrophe network of the German Society for Trauma Surgery (DGU).
