chemistry for PRAME and abnormal findings on FISH analysis, in our view, the concordance was not sufficient to enable PRAME immunohistochemistry to act as a surrogate for FISH testing. Our findings reiterate the principle that interpretation of problematic superficial melanocytic proliferations requires a synthesis of all the available data, including clinical scenario, morphological features, immunohistochemistry, and ancillary molecular investigations. Hypertrophic and acneiform forms are very rare variants of discoid lupus erythematosus (DLE), which can suppose a diagnostic and therapeutic challenge. We present a South American woman with facial disfiguring lesions of 7 years of evolution with clinical and histopathological characteristic of both hypertrophic and acneiform DLE. No criteria for systemic lupus erythematosus were present in the patient. To the best of our knowledge, no patients with concomitant hypertrophic and acneiform DLE have been previously reported in the literature.Hypertrophic and acneiform forms are very rare variants of discoid lupus erythematosus (DLE), which can suppose a diagnostic and therapeutic challenge.

The aims of this study were to assess if kidney tissue surrogates (KTSs) are superior to distilled water-iodine solutions in the emulation of energy-dependent computed tomography (CT) attenuation characteristics of renal parenchyma and to estimate attenuation thresholds for definite lesion enhancement for low-kV single-energy and low-keV dual-energy virtual monoenergetic imaging. A water-filled phantom (diameter, 30 cm) with multiple vials was imaged on a dual-source dual-energy CT (DS-DE) and a single-source split-filter dual-energy CT (SF-DE), both in single-energy mode at 80, 100, 120, 140 kVp and in dual-energy mode at 80/Sn150, 90/Sn150, and 100/Sn150 kVp for DS-DE and AuSn120 kVp for SF-DE. see more Single-energy images, linear-blended dual-energy images, and virtual monoenergetic imaging at energy levels from 40 to 190 keV were reconstructed. First, attenuation characteristics of KTS in solid and liquid consistencies were compared. Second, solid KTSs were developed to match the CT attenuation of unenhanced d from 16.6 to 33.2 HU and 3.2 to 68.3 HU for single-energy and dual-energy CT scan modes for DS-DE and from 16.1 to 34.3 HU and 3.3 to 92.2 HU for SF-DE. Kidney tissue surrogates more accurately emulate the energy-dependent CT attenuation characteristics of renal parenchyma for multienergy CT compared with conventional water-iodine approaches. Energy-dependent thresholds for definite lesion enhancement could facilitate lesion characterization when imaging at different energies than the traditional 120 kVp.Kidney tissue surrogates more accurately emulate the energy-dependent CT attenuation characteristics of renal parenchyma for multienergy CT compared with conventional water-iodine approaches.

Lutetium Dotatate radiopharmaceutical therapy (Lutathera) was approved by the United States Food and Drug Administration in 2018 and is used to treat somatostatin receptor positive neuroendocrine tumors. With all new radiopharmaceutical therapies, the radiation exposure to members of the public from the patient who received the therapy must be within regulatory limits and safe. If the patient will expose members of the public to too much radiation, the therapy must be performed on an inpatient basis. This paper shows that the administration of Lutathera can be done on an outpatient basis and provides safety and travel restrictions that should be communicated to the patient prior to leaving. The guidance presented herein serves as a basis for medical institutions looking to use Lutathera to treat patients.Lutetium Dotatate radiopharmaceutical therapy (Lutathera) was approved by the United States Food and Drug Administration in 2018 and is used to treat somatostatin receptor positive neuroendocrine tumors.

This review provides an overview of arthropod-borne virus (arbovirus) infections that are important causes of human neurological infections world-wide. As many of the individual viruses in a specific genus or family cause overlapping clinical syndromes, this review discusses important viruses in groups to highlight some of the similarities and differences in groups of neuroinvasive arbovirus infections. Arboviruses that cause neurological infections in humans continue to emerge and distribute to new regions. The geographic range of the vectors, the hosts and subsequent arbovirus infections in humans continues to expand and evolve. As emerging arboviruses move into new geographic regions, it is important to examine the associated epidemiological and clinical impacts of these infections as they enter new populations. Arboviruses from the Flaviviridae, Togaviridae and Bunyaviridae families continue to emerge and spread into new regions. The arboviruses within these virus families cause characteristic neurolations. An initial intracellular phase of usually extracellular bacterial pathogens displays an important strategy to hide from the host's immune system and antibiotics therapy. It helps the bacteria, including bacterial pathogens of airway diseases, to persist and eventually switch to a typical extracellular infection. Several infectious diseases of the lung are life-threatening and their control is impeded by intracellular persistence of pathogens. Thus, molecular adaptations of the pathogens to this niche but also the host's response and potential targets to interfere are of relevance. Here we discuss examples of historically considered extracellular pathogens of the respiratory airway where the intracellular survival and proliferation is well documented, including infections by Staphylococcus aureus, Bordetella pertussis, Haemophilus influenzae, Pseudomonas aeruginosa, and others. Current studies focus on bacterial factors contributing to adhesion, iron acquisition, and intracellular survival as well as ways to target them for combatting the bacterial infections.
