Despite of highly effective new therapeutic strategies, chemotherapy still is an important treatment option in metastatic melanoma. Since predictors of chemotherapy response are rare, drugs and regimens are currently chosen arbitrarily. The present study was aimed at the identification of molecular markers predicting the outcome of chemotherapy in melanoma. Tumor biopsies from metastatic lesions were collected from 203 stage IV melanoma patients prior to chemotherapy onset and used for gene expression profiling (n = 6; marker identification set), quantitative real-time PCR (n = 127; validation set 1), and immunohistochemistry on tissue microarrays (n = 70; validation set 2)...

Cell-derived vesicles in particular extracellular vesicles (EVs) such as microparticles (MPs) and microvesicles besides exosomes are raising more and more attention as a novel and unique approach to detect diseases. It has recently become apparent that disease specific MP signatures or profiles might be beneficial to differentiate chronic liver diseases such as non-alcoholic fatty liver disease and chronic hepatitis C, to monitor their progression or possibly to assess treatment outcome. Therefore EVs might serve as a novel inexpensive and minimally invasive method to screen risk patients for the outbreak of a disease even before the initial symptoms, to follow up treatment complications and disease relapse...

Merkel cell carcinoma (MCC) is an aggressive, polyomavirus-associated skin cancer. Robust cellular immune responses are associated with excellent outcomes in patients with MCC, but these responses are typically absent. We determined the prevalence and reversibility of major histocompatibility complex class I (MHC-I) downregulation in MCC, a potentially reversible immune-evasion mechanism. Cell-surface MHC-I expression was assessed on five MCC cell lines using flow cytometry as well as immunohistochemistry on tissue microarrays representing 114 patients...

Abdominal actinomycosis is a rare, chronic and slowly progressive granulomatous disease. The clinical presentation of abdominal actinomycosis shows a great variability and it often mimics other intraabdominal pathologies like chronic inflammatory bowel diseases or malignancies. A correct diagnosis can rarely be established before radical surgery especially in patients with advanced tumors and an acute clinical presentation. Actinomyces are considered to be residential saprophytes in the gastroinstetinal tract and require a mucosal lesion to cause an opportunistic infection...

The skeleton is a potential metastatic target of many malignant tumors. Up to 85% of prostate and breast cancer patients may develop bone metastases causing severe pain syndromes in many of them. In patients suffering from multilocular, mainly osteoblastic lesions and pain syndrome, radionuclide therapy is recommended for pain palliation. Low-energy beta-emitting radionuclides ((153)samarium-ethylenediaminetetrameth-ylenephosphonate (EDTMP) and (89)strontium) deliver high radiation doses to bone metastases and micrometastases in the bone marrow, but only negligible doses to the hematopoietic marrow...

A 39-year-old man experienced total obstruction of a distal tracheal plastic stent by a tumor mass, preventing effective ventilation and resulting in cardiac arrest. Resuscitation by emergency bedside venoarterial extracorporeal membrane oxygenation (ECMO) permitted time to physically remove the obstructing tumor and reestablish successful ventilation and liberation from ventilatory support. We review several other reported cases of emergency ECMO to resuscitate patients with acute airway obstruction.

Merkel cell carcinoma (MCC) is a rare and highly aggressive skin cancer associated with the Merkel cell polyomavirus (MCV). As MCC cell lines show oncogene addiction to the MCV T antigens, pharmacologic interference of the large T antigen (LTA) may represent an effective therapeutic approach for this deadly cancer. In this study, we investigated the effects of IFNs on MCC cell lines, especially on MCV-positive (MCV(+)) lines. Type I IFNs (i.e., Multiferon, a mix of different IFN-α subtypes, and IFN-β) strongly inhibited the cellular viability...

A key host response to limit microbial spread is the induction of cell death when foreign nucleic acids are sensed within infected cells. In mouse macrophages, transfected DNA or infection with modified vaccinia virus Ankara (MVA) can trigger cell death via the absent in melanoma 2 (AIM2) inflammasome. In this article, we show that nonmyeloid human cell types lacking a functional AIM2 inflammasome still die in response to cytosolic delivery of different DNAs or infection with MVA. This cell death induced by foreign DNA is independent of caspase-8 and carries features of mitochondrial apoptosis: dependence on BAX, APAF-1, and caspase-9...

BACKGROUND: Electronic patient files generate an enormous amount of medical data. These data can be used for research, such as prognostic modeling. Automatization of statistical prognostication processes allows automatic updating of models when new data is gathered. The increase of power behind an automated prognostic model makes its predictive capability more reliable. Cox proportional hazard regression is most frequently used in prognostication. Automatization of a Cox model is possible, but we expect the updating process to be time-consuming...

The effect of newly acquired central pareses on functional MRI (fMRI) signal pattern is not known, since up to now all investigated patients were examined while they already experienced the motor weakness. We describe the first prospective and controlled study demonstrating the impact of new, acquired central pareses on fMRI motor activation pattern. Six patients suffering from a new central paresis after resection of a brain tumor infiltrating the central region were prospectively compared with a control group of five patients without postoperative paresis and a group of six healthy, age-matched controls who were investigated at two time points...

Veno-occlusive disease (VOD) is a rare complication of chemotherapy in children with cancer. In the literature successful treatment of severe VOD has not been well determined. The authors report a 5-year-old boy with Willms tumor whose condition was complicated with VOD while receiving chemotherapy. He was treated successfully with high-dose methylprednisolone. After therapy, the clinical signs of VOD, such as abdominal ascites, oliguria, and jaundice, disappeared without any adverse effects of therapy.

OBJECTIVE: To demonstrate whether cortical activation within different cortical motor regions in neurosurgical patients varies with the degree of paresis induced by mass lesions near the central region. METHODS: A total of 110 patients with brain tumors infiltrating the central region and with varying degrees of paresis were investigated employing fMRI during the performance of hand motor tasks. The percent signal change between rest and activation was calculated for four cortical regions: primary motor cortex (M1), supplementary motor area, premotor area, and superior parietal lobule...

Prognosis was analyzed as a function of histologic grade, axillary gland spread and hormonal receptors in a consecutive series of 1000 patients with breast cancer (stages I and II) treated by conservative tumorectomy and axillary curettage, combined with radiotherapy, and followed up for between 3 and 12 years. The three factors analyzed are of major importance in that they constituted a veritable tumoral identity card. Grade I tumors, the absence of glandular spread and the presence of hormonal receptors are correlated with cancer of good prognosis, whereas grade III tumors, major axillary spread and absence of hormonal receptors are related to a poor prognosis...

Acute abdominal pain is the presenting manifestation in approximately 30% of all patients with Willms' tumor. In a small proportion of these patients this pain is significant enough to engender a diagnosis of an acute surgical abdomen. Six of 38 patients with Wilms' tumors treated between the years 1965 and 1975 at the Shands Teaching Hospital of the University of Florida Medical Center have had significant pain. Our experience with these patients emphasizes the importance of thoroughly palpating the abdomen of any child with a suspected acute surgical condition, following induction of anesthesia and prior to initiating the operation...
