Primary malignant melanoma occurs most often in the skin and much less frequently in the choroid layer of the eyes, in the leptomeninges, oral cavity, nasal mucosa, pharynx, esophagus, bronchus, under the nail and vaginal or anorectal mucosa. Primary melanoma of the gastrointestinal tract has been confirmed for lesions occurring in the esophagus, stomach, small bowel, and anorectum through several published reports, as these are the areas where melanocytes normally exist. The occurrence of primary malignant melanoma in the colon is relatively rare, because melanocytes are embryologically absent in the large bowel...

BACKGROUND: Most clinical guidelines in dermatology are encyclopaedic, covering a disease and its aetiology, diagnosis, treatment and prevention in their entirety. The usability and uptake of guideline recommendations might be improved by guidelines that are more concise and address specific questions ranked by users according to their perceived importance. OBJECTIVE: To survey the largest association of dermatologists in Europe, identify which questions in their everyday practice they felt would benefit from short, evidence-based guidance, and rank these systematically...

Distinct metastasis is one of the main causes of breast cancer (BC)-related mortality and epithelial-mesenchymal transition (EMT) is a primary step in metastasis dissemination. On the other hand, doxorubicin (DOX) is an effective chemotherapeutic agent against BC; unfortunately, its clinical use is limited by dose-dependent side effects. Therefore, extensive efforts have been dedicated to suppressing metastasis of BC and also to overcome DOX side effects together with keeping its antitumor efficacy. Studies supported the role of oleuropein (OLEU) in reducing DOX-induced side effects besides its antitumor actions...

PURPOSE: Tumors that secrete large volumes of mucus are chemotherapy resistant, however, mechanisms underlying this resistance are unknown. One protein highly expressed in mucin secreting breast cancers is the secreted mucin, Mucin 2 (MUC2). While MUC2 is expressed in some breast cancers it is absent in normal breast tissue, implicating it in breast cancer. However, the effects of MUC2 on breast cancer are largely unknown. This study examined the role of MUC2 in modulating breast cancer proliferation, response to chemotherapy and metastasis...

Nocardiosis is caused by various species of Nocardia and typically occurs as an opportunistic infection. It frequently disseminates, most often involving the lungs, subcutaneous tissues and central nervous system. It has rarely been reported to affect native heart valves. We report the case of a 64-year-old man with disseminated nocardiosis involving the brain, lungs, muscle and tricuspid valve of a transplanted heart. Following antimicrobial therapy, the patient improved clinically and there was no evidence of residual infection on follow-up imaging...

The main cause of cancer-related mortality, metastasis, is a complex, multi-step process. The extracellular matrix (ECM) component of solid tumors has been implicated in metastatic progression; however, the ECM exists as a complex macromolecular substrate and it is unclear how its molecular composition promotes cancer progression. ECM homeostasis is regulated by various secreted proteins including cross-linkers (e.g., lysyl oxidases and transglutaminases), modifying enzymes (e.g., sulfatases and extracellular kinases), proteases (e...

OBJECTIVE: To develop and disseminate an automated item generation (AIG) system for retrieval practice (self-testing) in radiology and to obtain trainee feedback on its educational utility. MATERIALS AND METHODS: An AIG software program (Radmatic) that is capable of generating large numbers of distinct multiple-choice self-testing items from a given "item-model" was created. Instead of writing multiple individual self-testing items, an educator creates an "item-model" for one of two distinct item styles: true/false knowledge based items and image-based items...

T2Candida that was positive for C. albicans/C. tropicalis supported antifungal treatment of a patient with hematogenously disseminated candidiasis and septic shock in whom blood cultures were negative. T2Candida, used and interpreted as a Bayesian biomarker, can identify patients with candidemia who are missed by blood cultures, including those receiving antifungal treatment.

In response to recent increases in the dissemination of Web-based parenting supports, an important consideration is whether the core benefits of self-directed participation in online parenting interventions are counterbalanced by issues such as high dropout and noncompletion rates commonly reported within the Internet intervention literature. This study outlines a randomized controlled trial of Triple P Online, a Web-based variant of the Triple P-Positive Parenting Program, delivered with varied levels of support scaffolding...

Many aspects of rickettsial infections have been characterized, including pathogenic and immune pathways, as well as mechanisms of rickettsial survival within the vertebrate host and tick vector. However, there is a remarkable paucity of studies focused on the complex pathogen-vector-host interactions during tick feeding. Therefore, our objective was to develop a tick transmission model of spotted fever group rickettsial infection to study the initial events in disease development. The most appropriate strain of mouse was identified to be evaluated as a transmission model, and the course of infection, bacterial levels, histopathologic changes, and antibody response during tick transmission in mice infested with Amblyomma maculatum ticks carrying the emerging pathogen, Rickettia parkeri, were further studied...

Indigenous small cyprinid fish species play an important role in Great Lakes ecosystems and also comprise the backbone of a multimillion-dollar baitfish industry. Due to their widespread use in sport fisheries of the Laurentian Great Lakes, there are increasing concerns that baitfish may introduce or disseminate fish pathogens. In this study, we evaluated whether baitfish purchased from 78 randomly selected retail bait dealers in Michigan harbored fish viruses. Between September 2015 and June 2016, 5,400 baitfish divided into 90 lots of 60 fish were purchased...

REVIEW
Gaspar Banfalvi
The in vitro susceptibility of gentamicin fractions against Fusarium growth was the subject of this retrospective study. Fusariosis was earlier an exceptionally rare human disease and an unrealistic idea to treat soil saprophytes and plant pathogens with expensive antibiotics such as gentamicins or their minor components. Disseminated fusariosis is now the second most frequent lethal fungal infection after aspergillosis especially in neutropenic patients with hematologic malignancy. Results of this study obtained between May and November 1973 were interesting but not practicable and remained unpublished...

BACKGROUND: Despite the wide usage of miniscalpel-needles (MSNs), information about MSN treatment-related adverse events (AEs) is insufficient. As the definition of AE might vary among physicians, without an exact definition for pain and hemorrhage, it is difficult to provide accurate information about AEs in MSN treatment to physicians, researchers, and patients. The aim of our study is to reach a consensus about the items and definitions of AEs that should be included in the survey form for prospective observational multicenter studies to record MSN treatment-related AEs...
