Wir beobachteten eine durchschnittliche Größenzunahme der neuen Areolen um 13,9 % bei Vollhauttransplantation aus der Leiste und 34,6 % bei Vollhauttransplantation aus den oberen Augenlidern. Die Patientinnen sollten präoperativ über Ausbleichen und Größenveränderungen der neuen Areola informiert werden.in English, German Der Ausbruch des Coronavirus SARS-CoV-2 hat inzwischen viele Länder weltweit erreicht. Trotz weitreichender Maßnahmen zur Eindämmung der Ausbreitung steigen die Fallzahlen kontinuierlich weiter. Die Diagnose der durch SARS-CoV-2 hervorgerufenen COVID-19 Erkrankung erfolgt mittels Polymerasekettenreaktion aus Proben des Respirationstrakts und computertomographischer Bildgebung der Lunge. Die Erkrankung kann asymptomatisch oder mild verlaufen und sich mit Fieber oder trockenem Husten manifestieren. Eine gefürchtete schwere Verlaufsform von COVID-19 ist die Entwicklung eines ARDS (acute respiratory distress syndrome). Da insbesondere schwere Krankheitsverläufe oftmals eine multidisziplinäre Vorgehensweise erfordern, besprechen wir hier anhand einiger 18F-FDG-PET/CT Fallbeispiele, welche Rolle die Nuklearmedizin bei COVID-19 einnehmen könnte.AIM  Recently, textural parameters assessed in FDG-PET/CT as surrogate marker for tumor heterogeneity have been shown to provide prognostic power. Therefore, we investigated the use of such parameters in FDG-PET/CT examinations before the start of immunotherapy with vemurafenib or ipilimumab in patients with malignant melanoma. METHODS  In this retrospective analysis 26 patients with histologically proven advanced melanoma were included. FGD-PET/CT was performed before the start of treatment either with vemurafenib (n = 9) or ipilimumab (n = 17) and tumors were analyzed for textural parameters as well as conventional PET features. Lesions were classified as responding or not responding following PERCIST criteria. ROC analysis was performed to analyze the predictive power and cut-off values. In addition, the change of maximum SUV of the lesions between pretherapeutic PET/CT and another PET/CT performed about 12 weeks after start of treatment was evaluated and correlated with the pretreatment parameters. RESULTS  In both groups, six textural parameters showed statistically significant predictive power as well as the metabolic tumor volume. In the group treated with vemurafenib eight additional textural parameters as well as the maximum and mean SUV and the TLG showed significance. A statistically significant correlation between the change of maximum SUV in the course of treatment and the pretherapeutic parameters was found in both treatment groups for three textural features. CONCLUSION  In patients with malignant melanoma textural parameters in pretherapeutic FDG-PET/CT examinations seem to have prognostic power for treatment response of immunotherapy with vemurafenib and ipilimumab. This can be an important step towards personalized tumor therapy. © Georg Thieme Verlag KG Stuttgart · New York.The number of total knee arthroplasties (TKAs) performed in the United States has increased considerably in recent years, with a major contribution from younger patients. Maximizing survivorship of these implants has always been a point of emphasis. Early TKA designs with cementless fixation were associated with high rates of complications and implant failures. However, recent advances in cementless designs have shown excellent results. The decision to use cemented or cementless fixation for patients undergoing TKA is typically based on the surgeon's experience and preference. However, several patient characteristics must also be taken into account. The purpose of this review was to describe the clinical outcomes of studies in which a cementless TKA system was utilized for patients who (1) were less than 60 years of age, (2) were greater than 75 years of age, (3) were obese, (4) had rheumatoid arthritis, and (5) had osteonecrosis of the knee. Based on the studies included in this review, it appears that cementless fixation is a viable option for patients who have all of the above demographics.

Therefore, this study analyzed (1) incidence, (2) patient demographics, (3) patient course, and (4) patient outcomes in obese and morbidly obese patients undergoing sd-BTKA in the United States from 2009 to 2016. The National Inpatient Sample was queried for all sd-BTKA patients from 2009 to 2016, yielding 39,901 obese and 20,394 morbidly obese patients. Analyzed variables included overall incidence, age, length of stay (LOS), sex, race, payer, Charlson comorbidity index (CCI) status, disposition, complications, location/teaching status, region of hospital, costs, and charges. Categorical variables were evaluated with chi-square analysis, while continuous variables were analyzed by Student's t-tests. Overall, the number of sd-BTKAs decreased over the study period, although the proportion of both obese and morbidly obese patients increased (p  less then  0.001 for all). The most common CCI status, 3 + , decreased in proportion for both groups (p  less then  0.001 for all). Hospital costs decreased and charges increased for both groups (p  less then  0.001 for all). Selleckchem ONO-7475 Mean LOS decreased and patients were most commonly discharged to skilled nursing facilities, although these proportions decreased (p  less then  0.001 for all). Respiratory failures (p  less then  0.001 for all) increased for both groups, while proportion of deep vein thromboses and hematomas/seromas (p  less then  0.001 for all) increased for obese patients and proportion of pulmonary emboli (p  less then  0.001) increased for morbidly obese patients. The results of this study appear to portray improving optimization and patient selection of higher body mass index (BMI) individuals undergoing this procedure. More information is needed comparing the safety of the sd-BTKA across patients of all BMI groups. Thieme Medical Publishers 333 Seventh Avenue, New York, NY 10001, USA.
