Research paper thumbnail of Hyperkalemia Following Parathyroidectomy in Patients with Renal Hyperparathyroidism—New Thresholds for Urgent Perioperative Dialysis

Perioperative hyperkalemia may lead to devastating cardiac complications. Distinct preoperative thresholds for serum potassium levels (SPL) were defined, but neither their usefulness nor consecutive risks are understood. This study compared the results and efficacy of different clinical procedures in preventing or treating perioperative hyperkalemia, including postoperative urgent hemodialysis (UHD). Methods: Patients from Charité-Universitätsmedizin Berlin and Rheinland Klinikum Lukaskrankenhaus, Neuss, undergoing PTX due to SHPT between 2008 and 2018 were analyzed retrospectively with regard to demographic parameters, surgery specific conditions and perioperative laboratory results. Comparisons of patient values from both centers with focus on pe...

Common criteria for assessing therapy response simplify measuring liver metastasis, as full 3D quantification is very time-consuming. Therefore, we trained a deep-learning model using manual 3D segmentation of liver metastases and hepatic parenchyma in 278 Gd-EOB MRI scans of 149 patients with neuroendocrine neoplasms (NEN). The clinical relevance of the model was evaluated in 33 additional consecutive patients with NEN and liver metastases, comparing the model’s segmentation of baseline and follow-up examinations with the therapy response evaluation of an expert multidisciplinary cancer conference (MCC). The model showed high accuracy in quantifying liver metastases and hepatic tumor load, and its measurements matched the response evaluation of an MCC so that its use...

Research paper thumbnail of CARS microscopy for the visualization of micrometer-sized iron oxide MRI contrast agents in living cells

Despite the great potential of MPIOs for in vivo imaging of labeled cells, little is known on the intracellular localization of these particles following uptake due to the lack of techniques with the ability to monitor the particle uptake in vivo at single-cell level. Here, we show that coherent anti-Stokes Raman scattering (CARS) microscopy enables non-invasive, label-free imaging of MPIOs in living cells with submicron resolution in three dimensions. CARS allows simultaneous visualization of the cell framework and the MPIOs, where the particles can be readily distinguished from other cellular components of comparable dimensions, and localized inside the cell.

Dies unterscheidet sich von anderen Ländern wie z. B. den USA und UK, bei denen das intraoperative Neuromonitoring in weniger als der Hälfte der Schilddrüsenoperationen genutzt wird [1]. Für die Nutzung des IONM spricht jedoch die damit verbundene Sicherheit, postoperative Stimmbandparesen bereits intraoperativ zu detektieren und entsprechend die OP-Strategie anpassen zu können. Ob die Zahl der einseitigen N.-laryngeus-recurrens-Paresen (NLRP) dadurch gesenkt wird, ist jedoch weiterhin fraglich und hängt von unterschiedlichsten Faktoren ab.

Research paper thumbnail of Heterotopic ileal pancreas with lipoma and coexisting fibromatosis associated with a rare case of gastrointestinal bleeding. A case report and review of the literature

This is a rare pathological and surgical entity which remains mostly asymptomatic. We present the case of a 28-year-old male, who was admitted to hospital because of a history of blood in bowel movements. After a normal gastroscopy and colonoscopy, Tc99m-tagged red blood cells scintigraphy showed enrichment in the right lower abdomen. At double-balloon endoscopy, a intraluminal polypoid mass 8 cm in diameter was revealed 120 cm from the ileocecal valve. The initial macroscopic diagnosis was a gastrointestinal stromal tumor. During surgery, the diagnosis of heterotopic pancreas with lipoma and fibromatosis was made. To our knowledge this is the first case of ileal heterotopic pancreatic tissue and lipoma described to date in the literature. Ileal heterotopic pancreas is a rare entity with potentially life-threatening complications, local...

As the general symptoms of a pregnancy might cover the clinical presentation, diagnosing remains challenging. We present one additional case of a post-partum insulinoma, combined with a systematic review of the literature to sum up relevant details in diagnosis and treatment. A systematic request of Pubmed/Medline was conducted using the following terms: “insulinoma AND pregnancy” and “insulinoma” for a second request of ClinicalTrials.gov. All publications concerning pregnant or post-partum women with insulinoma were included. Thirty-six cases could be identified for analysis. Each publication was reviewed for demographic, diagnostic and therapeutic data. The most frequent clinical signs were unconsciousness and neurological symptoms. 64.9% were diagnosed during early pregnancy and 35.1% post-partum. 91.9% underwent surgery with a third resected dur...

Adrenal metastasis of hepatocellular carcinoma (HCC) is a rare entity and can be treated by resection, local ablative therapy, or systemic therapy. Unfortunately, data about treatment outcome, especially in liver transplant recipients, are rare. Patients and Methods. From 2005 to 2015, 990 liver resections and 303 liver transplantations because of HCC were performed at our clinic. We retrospectively analyzed treatment outcome of the patients with metachronous adrenal metastasis of HCC, who received either resection, local ablation, or surveillance only. Results. 10 patients were identified (0.8%). 7 patients received liver transplantation for primary HCC therapy, 3 liver resection, and 1 a local ablative therapy. 8 patients underwent adrenalectomy (one via retroperitoneoscopy), one was treated with local ablation, and one had surveillance only. Seven out of eight patients had no surgical complications and one experienced a pancreatic fistula, treated conservatively. 37...

Research paper thumbnail of Influence of Gender on Therapy and Outcome of Neuroendocrine Tumors of Gastroenteropancreatic Origin: A Single-Center Analysis

In gastrointestinal cancer, influence of sex on outcome has been discussed, while this has not been the case in neuroendocrine tumors. Overall, the incidence of neuroendocrine neoplasms is rising, especially for appendiceal neuroendocrine neoplasms in women. Also, women seem to have a slight advantage in response to therapy, especially for liver metastases. Objectives: This single-center analysis aimed to investigate gender-specific differences in our cohort related to distribution, therapy, and outcome. Methods: Patients from the NET registry as well as the clinic database were evaluated retrospectively concerning overall survival and response to therapy with respect to gender. A subgroup analysis was carried out for patients with low grading and response to chemotherapy, as well as for patients with good and moderate grading receiving peptide receptor radionuclide therapy and for a group of patients with liver surgery. Results: No specific differences could be detected for overall survival or response to therapy between male and female patients. Mean survival was estimated with 242.2 months (±10.39 SD) altogether and 221.7 months (± 13.02 SD) for male patients and 253.5 months (±15.24 SD) for female patients from the NET registry from initial diagnosis. There was no significant difference between female and male patients (p = 0.136). For patients receiving chemotherapy, overall survival from initial diagnosis was calculated with 26 months (±2.59) and did not show any significant differences between female and male patients 24.8 months (±2.81 SD) vs. 27.8 months (±3.86 SD, p = 0.87). Patients undergoing peptide receptor radionuclide therapy showed a median progression-free survival of 26.9 months (±2.82 SD), with 16.9 (±5.595 SD) and 26.9 months (±3.019 SD) for male and female patients, respectively (p = 0.2). In the group of patients with liver surgery, female patients reached an estimated overall survival of 64.7 months (±4.16 SD), male patients 65.1 months (±2.79 SD, p = 0.562). Conclusion: Our cohort did not reveal significant differences in outcome and response to therapy with regards to gender.
