The Incidental Discovery of an Ileal Conduit Calculus: A Case Report.

In patients who have undergone radical cystectomy, urinary diversion procedures such as ileal conduits may pose a considerable problem for urologists when they result in stone formation. While an ileal conduit stone is only one of many potential complications of this procedure, its management may be particularly challenging; symptoms and treatments vary depending on factors such as stone location, composition, and the patient's BMI. We present a unique case of a 91-year-old male with a history of prostate and bladder cancer status post-radical prostatectomy, cystectomy, and ileal conduit who presented to the emergency department complaining of abdominal pain, nausea, vomiting, and disorientation for the last 24 hours. The patient was diagnosed with a complete bowel obstruction secondary to gallstone ileus. Consequently, an exploratory laparotomy was performed, which revealed that his small bowel obstruction was not caused by gallstone ileus but rather secondary to an internal hernia and volvulus associated with a previous bowel resection and anastomosis. The stone that was originally thought to be causing the small bowel obstruction turned out to be a 3.3 cm stone in his ileal conduit, which ultimately had no part in causing the patient's small bowel obstruction. Calculus formation is an infrequent complication of ileal conduit placement. Our aim in presenting this case is to increase awareness of this rare complication that can arise without symptoms with the hopes of increasing early intervention and improving outcomes.

Myocardial Bridging as a Differential Diagnosis for Myocardial Infarction: A Case Report.

We present a case of a 55-year-old male who presented to the emergency department with complaints of acute onset of chest pain. As part of the workup, an electrocardiogram (ECG) revealed ST-segment elevation in leads V1-V5. Upon cardiac catheterization, myocardial bridging of the left anterior descending (LAD) artery was discovered without evidence of any obstructive coronary artery disease. The purpose of this report is to add to the existing literature that myocardial bridging, although traditionally thought to be a benign pathology, can also present risks for ischemia and infarction.

A Rare Phenomenon of Isaacs Syndrome: A Case Report.

We illustrate the case of a 71-year-old male who initially presented with sudden onset muscle weakness and ambulation difficulty. Following medication discontinuation and additional clinical studies, he failed to improve and was admitted to the hospital 11 weeks later. He had an associated 20-pound weight loss, sudorrhea, and muscle stiffness only when weight-bearing. A complete connective tissue cascade and a paraneoplastic panel were obtained. Clinical diagnosis of acquired neuromyotonia, or Isaacs syndrome (IS), was made, and he began experiencing significant improvement after intravenous steroid infusion. IS is a rare disease that has been poorly documented in the literature. There have only been a limited number of cases which are globally documented. One of the difficulties is a lack of definite autoantibody with which to correlate the disease; however, there has been some correlation linking the disease to voltage-gated potassium channels. Ultimately, the diagnosis should be driven by history and clinical presentation. The aim of this case report is to highlight a rare disease process and increase awareness among clinicians. We also describe the associated evaluation and recommended treatment for an optimal patient outcome.

Variability of Steroid Response Time in Polymyalgia Rheumatica: A Case Report.

We present a unique case of a 75-year-old Caucasian female who presented with a two-month history of unrelenting proximal muscle pain and stiffness in the neck, shoulders, and pelvic girdle that lasted for 45 minutes each morning upon waking. Due to clinical suspicion of polymyalgia rheumatica (PMR), the patient was started on the standard therapy of low-dose glucocorticoid therapy and was noted to have a dramatic improvement in terms of pain, strength, mobility, and range of motion. Current literature shows high variability in the standard response time to treatment. Typical resolution of symptoms occurs within a span of one day to months. The case presented in our study shows symptom resolution as well as marked improvement in muscle strength and mobility within 12 hours. The purpose of this case report is to provide additional information for physicians when considering symptom-resolution time related to low-dose glucocorticoid therapy and PMR. Additionally, we briefly explore the literature on the correlation between giant cell arteritis (GCA) and glucocorticoid therapy for PMR as well as the data associated with adjuvant therapy using immunomodulatory treatment.

Evaluating Acute Bilateral Foot Drop: A Case Report.

We illustrate the case of an 84-year-old Caucasian female who presented with complaints of bilateral lower extremity weakness and ambulation difficulties complicated by a unilateral deep venous thrombosis. Physical examination on hospital admission revealed an acute onset of bilateral foot drop with pes cavus deformity. Bilateral foot drop has been associated with a more chronic presentation due to metabolic, neurologic, and musculoskeletal etiologies. Acute onset of bilateral foot drop has been poorly defined in the literature and is considered a rare pathologic phenomenon, requiring additional investigation into the underlying cause of the presentation. We hypothesize that a spinal cord compression at the T12-L1 level resulted in L5 nerve root compression, resulting in our patient's presentation. Definitive treatment has not been established for this condition; however, studies have been completed to evaluate surgical versus conservative approaches to help restore patients' ambulatory function. Our aim is to incorporate this case report into the limited current literature on acute bilateral foot drop as well as outline possible treatment methods to restore impaired functionality.

Layer-By-Layer Nanoparticle Vaccines Carrying the G Protein CX3C Motif Protect against RSV Infection and Disease.

Respiratory syncytial virus (RSV) is the single most important cause of serious lower respiratory tract infections in young children; however no effective treatment or vaccine is currently available. Previous studies have shown that therapeutic treatment with a monoclonal antibody (clone 131-2G) specific to the RSV G glycoprotein CX3C motif, mediates virus clearance and decreases leukocyte trafficking to the lungs of RSV-infected mice. In this study, we show that vaccination with layer-by-layer nanoparticles (LbL-NP) carrying the G protein CX3C motif induces blocking antibodies that prevent the interaction of the RSV G protein with the fractalkine receptor (CX3CR1) and protect mice against RSV replication and disease pathogenesis. Peptides with mutations in the CX3C motif induced antibodies with diminished capacity to block G protein-CX3CR1 binding. Passive transfer of these anti-G protein antibodies to mice infected with RSV improved virus clearance and decreased immune cell trafficking to the lungs. These data suggest that vaccination with LbL-NP loaded with the CX3C motif of the RSV G protein can prevent manifestations of RSV disease by preventing the interaction between the G protein and CX3CR1 and recruitment of immune cells to the airways.

Technical advance: introducing a novel metric, directionality time, to quantify human neutrophil chemotaxis as a function of matrix composition and stiffness.

A direct consequence of cellular movement and navigation, migration incorporates elements of speed, direction, and persistence of motion. Current techniques to parameterize the trajectory of a chemotaxing cell most commonly pair migration speed with some measure of persistence by calculating MSD, RMS speed, TAD, and/or CI. We address inherent limitations in TAD and CI for comparative analysis by introducing two new analytical tools to quantify persistence: directionality index and directionality time. With the use of these tools, we show that the mechanical properties of the underlying substrate contribute significantly to the regulation of human neutrophil chemotaxis toward fMLP on Fgn-, Col-, and Fn-coated gels of varying elasticity. The ß1-integrin ligand Col demonstrated mechanosensitive speed. In contrast, ß2-integrin ligand Fgn supported mechanosensitive persistence. Fn, recognized by ß1 and ß2 integrins, mechanoregulated speed and persistence. Blocking ß2 integrins of cells migrating on Fn identified an underlying ß2-integrin-directed modulation of persistence. These data demonstrate that individual components of the neutrophil chemotactic response show integrin dependence and are finely tunable with different ligand, mechanotactic, and chemotactic cues, underscoring the need for sensitive analytical methods.

Nanoparticle vaccines encompassing the respiratory syncytial virus (RSV) G protein CX3C chemokine motif induce robust immunity protecting from challenge and disease.

Nanoparticle vaccines were produced using layer-by-layer fabrication and incorporating respiratory syncytial virus (RSV) G protein polypeptides comprising the CX3C chemokine motif. BALB/c mice immunized with G protein nanoparticle vaccines produced a neutralizing antibody response that inhibited RSV replication in the lungs following RSV challenge. ELISPOT analysis showed that G nanoparticle vaccinated mice had increased levels of RSV G protein-specific IL-4 and IFN-γ secreting cells compared to controls following RSV challenge. Remarkably, RSV challenge of G protein nanoparticle vaccinated mice resulted in increased RSV M2-specific IL-4 and IFN-γ secreting T cells, and increased M2-specific H-2Kd-tetramer positive CD8(+) T cells in the lungs compared to controls. Cell type analysis showed vaccination was not associated with increased pulmonary eosinophilia following RSV challenge. These results demonstrate that vaccination of mice with the RSV G protein nanoparticle vaccines induces a potent neutralizing antibody response, increased G protein- and M2-specific T cell responses, and a reduction in RSV disease pathogenesis.

Advances in and the potential of vaccines for respiratory syncytial virus.

Respiratory syncytial virus (RSV) is the leading cause of serious lower respiratory track illness causing bronchiolitis and some mortality in infants and the elderly. Despite decades of research there is no licensed RSV vaccine. To enable the development of RSV vaccines, several major obstacles must be overcome including immature and waning immunity to RSV infection, the capacity of RSV to evade immunity and the failure of RSV infection to induce robust enduring immunity. Since the failure of the formalin-inactivated RSV vaccine trial, more cautious and deliberate progress has been made toward RSV vaccine development using a variety of experimental approaches. The scientific rational and the state of development of these approaches are reviewed in this article.

Impact of being placed at risk of Creutzfeldt-Jakob disease: a qualitative study of blood donors to variant CJD cases and patients potentially surgically exposed to CJD.

BACKGROUND: The study objective was to describe the emotional and behavioural responses to Creutzfeldt-Jakob disease (CJD) risk notification. METHODS: A qualitative study using 11 participants' interviews, which were analysed thematically with Framework Analysis. PARTICIPANTS: Six participants purposively selected from people exposed to surgical instruments used previously on patients with or at risk of CJD (any type; n = 60), and 5 participants from a cohort of blood donors to patients who subsequently developed variant CJD (n = 110). RESULTS: Notification was initially a shocking event, but with no lasting emotional impact. Those notified were convinced they were at extremely low risk of CJD and coped by not thinking about the information. Disclosure outside the immediate family was limited by fears of stigma. All expressed concern about the possibility of onward transmission and agreed notification was appropriate. Individual adherence to public health precautions varied from those who did nothing, apart from not donating blood, to those who consistently followed all advice given. This variation was informed by an assumption that information was always shared among health professionals. CONCLUSIONS: Factors contributing to minimising emotional distress following notification of CJD risk were evident. We found little evidence of sustained emotional distress. However, implementation of behaviours to minimise onward transmission, particularly in health care settings, was variable - this requires further investigation.
