Background: Cryptococcus neoformans is an encapsulated yeast and the most frequent cryptococcal species found in humans. Cryptococcosis is considered an opportunistic infection as it affects mainly immunosuppressed individuals. In humans, C. neoformans causes three types of infections: pulmonary cryptococcosis, cryptococcal meningitis and wound or cutaneous cryptococcosis.Case Presentation: An 81-year-old woman developed severe necrotizing cellulitis on her left arm without any preceding injury. The patient had been treated with systemic corticosteroids over twenty years for rheumatoid arthritis (RA). Skin biopsies of the wound area were initially interpreted as cutaneous vasculitis of unknown etiology. However, periodic acid Schiff staining and smear analysis later revealed structures consistent with Cryptococcus neoformans, and the infection was subsequently confirmed by culture. After the initiation of therapy with fluconazole 400 mg per day the general condition and the skin ulcers improved rapidly and the patient was discharged to a rehabilitation facility. Subsequently surgical debridement and skin grafting were performed.Conclusions: Opportunistic infections such as cryptococcosis can clinically and histologically mimic cutaneous vasculitis and have to be investigated rigorously as a differential diagnosis in immunosuppressed patients. © 2010 Probst et al; licensee BioMed Central Ltd.

BACKGROUND AND PURPOSE: The safety and efficiency of the dual-layer Woven EndoBridge (WEB) device has already been published. However, this international multicenter study sought to evaluate the safety of single-layer devices, which are the newest generation of the WEB intrasaccular flow-disrupter family. They have been designed to offer smaller-sized devices with a lower profile to optimize navigability and delivery, which may, in turn, broaden their range of use. MATERIALS AND METHODS: Data from all consecutive patients treated with a single-layer WEB device, in 10 European centers from June 2013 to May 2014 were included. Clinical presentations, technical details, intra-and perioperative complications, and outcomes at discharge were recorded. Clinical and angiographic data at last follow-up were also analyzed when available. RESULTS: Ninety patients with 98 WEB-treated aneurysms were included in this study. In 93 cases (95%), WEB placement was possible. Complete occlusion at the end of the procedure was obtained in 26 instances (26%). Additional treatment during the procedure (coiling and/or stent placement) was necessary in 12 cases (12.7%). Procedure-related complications occurred in 13 cases, leading to permanent neurologic deficits in 4 patients (4.4%). Early vascular imaging follow-up data were available for 44 patients (57%), with an average time interval of 3.3 months. Treatment-related morbidity and mortality rates at last follow-up were 2.2% and 1.1%, respectively. CONCLUSIONS: In this study, the feasibility and safety of the single-layer WEB device was comparable with that of the double-layer. However, further studies are needed to evaluate long-term efficacies.

During the last decades, symptomatic treatment of motor symptoms of Parkinson’s disease (PD) improved continuously and is reflected by long-range independency of the patient during the disease course. However, advanced stages of PD still represent an important challenge to patients, caregivers and treating physicians. In patients with advanced PD, interventional therapy strategies are increasingly applied. These device-related treatment strategies using pump-based continuous dopaminergic stimulation (CDS) or deep brain stimulation (DBS) opened new treatment options especially if motor complications predominate. Well-designed clinical studies on these interventional therapeutic approaches provided class 1 evidence for the efficacy of DBS and CDS in advanced PD and opened new perspectives for their use in earlier disease stages also. Therefore, careful selection of patients amenable to the (semi)invasive therapy options becomes more and more important and requires an interdisciplinary setting that accounts for (i) optimal patient information and awareness, (ii) selection of best individual treatment modality, (iii) training of relatives and caregivers, (iv) management of complications, and (v) follow-up care. Here, we address these topics by summarizing current state-of-the-art in patient selection, providing specificities of treatment options and troubleshooting, and defining steps towards an optimized patient-centered care. Interventional therapies pioneer in the area of individualized treatment approaches for PD, and may be complemented in the future by biomarker-based improved stratification and by closed-loop systems for adaptive therapeutic strategies. In the present review, we summarize the proceedings of an Expert Workshop on Parkinson’s disease held on November 22, 2014 in Frankfurt, Germany. © 2015, Springer-Verlag Wien.

Background: The German NOTES registry (GNR) is the largest published database for natural orifice transluminal endoscopic surgery (NOTES) worldwide. Although transvaginal cholecystectomy is the most frequent procedure in the GNR, the number of colorectal resections is increasing. The objective of this study was to analyze the first 139 colonic procedures of the GNR. Methods: All colonic procedures from the GNR were analyzed regarding patient- and therapy-related parameters. A multivariate analysis was conducted for transvaginal sigmoid resections regarding procedural time, hospital stay, conversion rate, and rate of complications. Results: From October 2008 to January 2013, 139 colon NOTES procedures (12 male, 127 female) were registered. Main diagnoses were sigmoid diverticulitis (85.6 %), colon carcinoma (9.4 %), and ulcerative colitis (3.6 %). Sigmoid resections (87.1 %), proctocolectomies (3.6 %), right-sided resections (2.9 %), left-sided resections (3.6 %), segmental resections (2.2 %), and 1 ileocecal resection (0.7 %) were performed. All procedures were conducted in transvaginal (87.8 %) or transrectal (12.2 %) hybrid technique, with a median of 3 percutaneous trocars. Conversions to laparoscopic technique were necessary in 3.6 % (none to conventional technique). Intraoperative complications were recorded in 2.9 % and postoperative complications in 12.2 %. The institutional case number in transvaginal sigmoid resections correlated negatively with procedural time (p=0.041) and the number of percutaneous trocars (p=0.002). Conclusion: The analysis of the first 139 colon NOTES operations of the GNR shows the feasibility of colon operations in hybrid technique, especially for transvaginal sigmoid resection as the most frequent procedure. © 2014 Springer-Verlag.

Broad based bifurcation aneurysms are challenging. Various endovascular techniques aim at stabilizing the coil package in the aneurysm. Among these, the waffle cone technique provides a viable alternative to Y stenting in selected cases, incorporating a less complex delivery, and the reduced inherent risk of a single stenting procedure compared with the use of two stents in Y configuration. Unlike conventional stents, the distal end of the new pCONus device opens like a blossoming flower inside of the aneurysm to facilitate the waffle cone technique. In a case with tandem unruptured broad based middle cerebral artery bifurcation aneurysms, the complex anatomical challenge was resolved by a unique combination of both techniques: two pCONus deployed in Y configuration, offering stable neck coverage for coiling both aneurysms. The angiographic results with complete occlusion of both aneurysms and the uneventful clinical course at 90 days with continued daily administration of dual antiplatelet therapy are encouraging.
