Advanced practice registered nurses, such as Nurse Practitioners (NPs), can be found working in a variety of settings. Niche practices, such as Interventional Radiology, are highly specialized areas and are often specialties in which few NPs get to orient through during their graduate nursing program clinical rotations. For the NP transitioning into an Interventional Radiology practice, formal on-the-job orientation and training can assist in gaining specialty-based knowledge and competencies in performing interventional procedures...

BACKGROUND: Traditionally, Billroth I procedure or bypass gastrojejunostomy were the recommended approaches for management of postcorrosive complete gastric outlet obstruction (GOO), whereas Heineke Mickulicz pyloroplasty was recommended for moderate mucosal injury with partial cicatrization. In this study, laparoscopic diamond antroduodenostomy was carried out as an alternative minimally invasive approach for cases with pyloric cicatricial obstruction. PATIENTS AND METHODS: Between January and December 2017, children who were referred to Pediatric Surgery Department, Cairo University Hospital, with GOO as a consequence of caustic liquid ingestions were included in this study...

Diagnosis of invasive aspergillosis (IA) is challenging, particularly in high-risk patients with lung lesions other than typical according to 2008-EORTC/MSG criteria. Even if microbiology is positive, they still remain unclassified according to 2008-EORTC/MSG. Quantitative polymerase chain reaction (qPCR) provides new mycological documentation of IA. This retrospective study assessed Aspergillus fumigatus real time qPCR (MycoGENIE®) in BAL to diagnose IA and identify azole-resistant strains. Clinical, radiological, and microbiological data from 114 hematology patients (69% HSCT recipients; 29% on mould active agents) from years 2012-2017 were collected; and 123 BAL samples were tested with qPCR (cutoff: Ct < 40) and galactomannan (GM, Platelia®, cutoff: 0...

Pelvic floor disorders negatively impact millions of women worldwide. Although there is a strong epidemiological association with childbirth, the mechanisms leading to the dysfunction of the integral constituents of the female pelvic floor, including pelvic floor skeletal muscles, are not well understood. This is in part due to the constraints associated with directly probing these muscles, which are located deep in the pelvis. Thus, experimental models and non-invasive techniques are essential for advancing knowledge of various phenotypes of pelvic floor muscle injury and pathogenesis of muscle dysfunction, as well as developing minimally invasive approaches for the delivery of novel therapeutics...

Cell-free DNA (cfDNA), which are small DNA fragments in blood derived from dead cells including tumor cells, could serve as useful biomarkers and provide valuable genetic information about the tumors. cfDNA is now used for the genetic analysis of several types of cancers, as a surrogate for tumor biopsy, designated as "liquid biopsy." Rhabdomyosarcoma (RMS), the most frequent soft tissue tumor in childhood, can arise in any part of the body, and radiological imaging is the only available method for estimating the tumor burden, because no useful specific biological markers are present in the blood...

Locoregional therapies are commonly used to treat patients with hepatocellular carcinoma. It has been noted for many years that locoregional therapies may have additional systemic effects other than simple tumor elimination. Immunological "side effects" have been described in response to locoregional therapies in animal studies and also in patients. With the advent of immunotherapy for hepatocellular carcinoma, there is an increasing interest in understanding how immunotherapy may be best combined with locoregional therapies...

Aspergillosis, which is saprophytic in nature, is known to cause massive destruction of paranasal sinuses in immunocompromised hosts, but in immunocompetent individuals invasive aspergillosis is rare. Diagnosis is posed from history, physical examination including anterior and posterior rhinoscopy, endoscopy of the nose and paranasal sinuses, radiological findings (CT and/or MRI), fungus cultures and histopathological examination. Non-specific presenting symptoms provide time for infection to extent from sinuses to vital surroundings such as bony, vascular and central nervous system structures, thereby increasing morbidity and mortality...
