Allogeneic mesenchymal stromal cells: Novel therapeutic option for mutated FLNA-associated respiratory failure in the pediatric setting.

Background: Mesenchymal stromal cell (MSC)-mediated therapeutic effects have been observed in the treatment of lung diseases. For the first time, this treatment was used as rescue therapy in a pediatric patient with a life-threatening respiratory syndrome associated with the filamin A (FLNA) gene mutation.

Methods: A child with a new pathogenic variant of the FLNA gene c.

Response by Twin Italian Hub Hospitals in a Double Seismic Event: A Retrospective Observational Investigation.

Introduction: The objectives of this study were to compare prevalence rates of different pathologies, ambulance system and emergency department management times, and patient survival and hazard ratios for codes 2 and 3 in two hub hospitals in Modena in the 36-month period across the stages of two major earthquakes in short sequence in Northern Italy in 2012.

Methods: Clinical records pertaining to the emergency care of patients were analyzed and only those assigned status codes 2 and 3 by ambulance professionals were included (if the assessment was confirmed by emergency department triage). The statistical analysis of data was divided by three time periods studied: before, during/between, and after the earthquakes.

Cerebral Stroke in a Teenage Girl with Paroxysmal Nocturnal Hemoglobinuria.

We report a case of paroxysmal nocturnal hemoglobinuria (PNH) in a 14 year-old girl presenting a cerebral arterial thrombosis. The initial diagnosis was carential anemia due to menarche following identification of slight macrocytic anemia, leucopenia and mild thrombocytopenia at routine blood analysis. The child was eventually referred to a children's hospital after the onset of progressive fatigue, anorexia and paleness.

Analysis of IL-6, IL-10 and IL-17 genetic polymorphisms as risk factors for sepsis development in burned patients.

Infection risk, sepsis and mortality after severe burn are primarily determined by patient age, burn size, and depth. Whether genetic differences contribute to otherwise unexpected variability in outcomes is unknown. We sought to determine whether there was an association between IL-6, IL-10 and IL-17 polymorphisms with cytokine production and development of sepsis.

Tiny percutaneous needle biopsy: An efficient method for studying cellular and molecular aspects of skeletal muscle in humans.

Needle biopsy is widely used to obtain specimens for physiological, anatomical and biochemical studies of skeletal muscle (SM). We optimized a procedure which we termed tiny percutaneous needle biopsy (TPNB), to efficiently gather good numbers of human satellite cells and single dissociated fibers for the functional study of skeletal muscle; these samples permit isolation of high-quality RNA and sufficient amounts of proteins to allow molecular analysis. Moreover, TPNB showed a clear advantage in that the technique was easier than other procedures used on healthy volunteers in human trials.

Reduction of plasma granzyme A correlates with severity of sepsis in burn patients.

The risk of mortality is high in burn patients and correlates with age, burn area extent, and sepsis. Immunosuppression has been reported to occur after severe burn. Cytotoxic cells possess specialized granules containing perforin and a group of serine proteases (granzymes).

Skin dendritic cells in burn patients.

The body's immunological response to burn injury has been a subject of great inquiry in recent years. Burn injury disturbs the immune system, resulting in a progressive suppression of the immune response that is thought to contribute to the development of sepsis. Dendritic cells (DCs) are potent antigen-presenting cells that possess the ability to stimulate naïve T cells.

Effects of local vibrations on skeletal muscle trophism in elderly people: mechanical, cellular, and molecular events.

Several studies have examined the effects of vibrations on muscle mass and performance in young healthy people. We studied the effects of vibrations on muscles of elderly male and female volunteers (65-85 years of age) diagnosed with sarcopenia. We applied mechanical vibrations locally (local vibrational training) to the thigh muscles at 300 Hz for a period of 12 weeks, starting with a session of 15 min stimulation once a week and increasing to three sessions of 15 min per week.

Serum Levels of Cortisol, Immunoglobulin, and C-reactive Protein in Burn Patients.

Thermal injury is known to induce alterations in the immune system, but the precise mechanisms have yet to be elucidated. It has been shown that thermal injury in more than 20% of the total body surface area (TBSA) leads to disturbances in the cortisol metabolism and the equilibrium of the hypothalamic-pituitary-adrenal axis. We investigated the temporal relationship between serum cortisol levels, C-reactive protein, and immunoglobulin levels in the post-burn period.

Circulating dendritic cells following burn.

Burns are associated with immune suppression and subsequent development of sepsis. Dendritic cells (DCs) are potent antigen-presenting cells that serve as a critical link between the innate and acquired immune systems, and are essential in coordinating the host response to pathogens. Using multicolour flow cytometry, the percentages of LIN(-) DR(+) CD11c(+) myeloid (mDC) and LIN(-) DR(+) CD123(+) plasmacytoid (pDC) subsets were determined in peripheral blood from 32 people (15 septic and 5 non-septic burn victims and 12 age- and gender-matched healthy controls, up to 20 days from injury).

Concentrations of cytokines IL-6 and IL-10 in plasma of burn patients: their relationship to sepsis and outcome.

Burn injury induces a suppression of the Th1 response, which is associated with an increased susceptibility to conditions of infection, morbidity, and mortality. It is well established that cytokines modulate the pathogenesis of burn injury. In this study, plasma levels of interleukin-6 (IL-6) and interleukin-10 (IL-10) were determined in burn patients and correlated with the severity of sepsis.

Decrease of circulating dendritic cells in burn patients.

Burn injury is associated with immune suppression and the subsequent development of sepsis. Severe burn injury is associated with depressed immune response, including a functional impairment of Th1 lymphocytes and natural killer cells and a decrease in interferon-a production. Dendritic cells (DCs) are potent antigen-presenting cells and play a key role in T cell activation; they are essential in coordinating the host response to pathogens.

Staphylococcal Scalded Skin Syndrome: Criteria for Differential Diagnosis from Lyell's Syndrome. Two Cases in Adult Patients.

A review of the relative international literature of the last few years is followed by a description of two cases of staphylococcal scalded skin syndrome in adults. As in both cases the initial diagnosis was that of Lyell's syndrome, the main criteria for the differential diagnosis of the two pathologies are considered in order to permit specific and effective treatment.

Progressive disorganization of the excitation-contraction coupling apparatus in aging human skeletal muscle as revealed by electron microscopy: a possible role in the decline of muscle performance.

An impairment of the mechanisms controlling the release of calcium from internal stores (excitation-contraction [EC] coupling) has been proposed to contribute to the age-related decline of muscle performance that accompanies aging (EC uncoupling theory). EC coupling in muscle fibers occurs at the junctions between sarcoplasmic reticulum and transverse tubules, in structures called calcium release units (CRUs). We studied the frequency, cellular localization, and ultrastructure of CRUs in human muscle biopsies from male and female participants with ages ranging from 28 to 83 years.

Oxidative stress after moderate to extensive burning in humans.

Lipid peroxidation products, lipid antioxidants, and hematologic and blood chemistry changes were evaluated in plasma of patients after acute burning injury involving 10% (n=8), 20% (n=8), and 40% (n=5) of total body surface area (TBSA), 24 h after burning (baseline) up to 30 days after. Markedly increased plasma levels of malondialdehyde (MDA) were observed at baseline in all patients, according to the extent of the injury, then the values declined progressively. However, levels of MDA remained above normal up to 30 days even in less injured patients.

Development and use of a prehospital-oriented EMS computer bulletin board service.

Objective: To describe a Level 1 trauma center's response to the need for centralized information for EMS providers by implementing a computer bulletin board service (BBS). This service permits rapid retrieval of continuing education and reference information as well as an electronic forum for EMS-related issues.

Methods: A desktop computer with a modem supporting 14.

Cognitive trauma care is undervalued: adult splenic injury as a paradigm.

Nonoperative management (NOM) of adult splenic injury is evolving. Economic aspects of NOM have not been examined. We hypothesize that NOM reduces hospital and professional charges.

Expression of PSA-N-CAM in human neuroblastoma cells induced to neuronal differentiation by retinoic acid.

The neural cell adhesion molecule (N-CAM) plays a significant role in the development of the nervous system. Three different isoforms of the molecule have been described, with molecular masses of 180, 140 and 120 kDa, whose differential expression in neurons seems to be related to their state of differentiation. We took advantage of the use of the human neuroblastoma cell line LAN-5, which can be differentiated in vitro by retinoic acid (RA) into neuronal cells, for studying the expression of N-CAM isoforms, and their polysialic acid (PSA) content, at the protein and mRNA levels.

Sternal fractures in blunt chest trauma: a practical algorithm for management.

A retrospective review of the medical records of blunt trauma patients with sternal fracture admitted to a level 1 trauma center from June 1990 to June 1993 was undertaken to determine the relationship between sternal fractures and clinically significant myocardial injury, and to assess the usefulness of cardiac evaluation and monitoring in these patients. Of 33 patients with sternal fracture, 31 were in motor vehicle crashes and 2 were pedestrians struck. All had Glasgow Coma Scale score = 15.

Peritoneoscintigraphy in the diagnosis of traumatic diaphragmatic rupture.

Current diagnostic modalities for traumatic diaphragmatic hernia (TDH) have limitations. Prior models differ from human injury. This study evaluates peritoneoscintigraphy in a rabbit model of TDH simulating human blunt injury.

Antibiotic patterns associated with fungal colonization in critically ill surgical patients.

Fungal infections (FI) in surgical patients are increasing; mortality approaches 50 per cent. Prior studies identified factors predicting fungal colonization (FC) including broad spectrum antibiotics (BSA). This study investigates antibiotic patterns predicting FC.

"Adult" trauma surgeons with pediatric commitment: a logical solution to the pediatric trauma manpower problem.

Pediatric trauma care by "adult" surgeons is debated, despite the paucity of pediatric trauma surgeons; 424 patients < or = 17 admitted to a Level I Center run by "adult" surgeons were analyzed. Demographics mirrored NPTR (mean ISS 11.5; mean age 10).

Computed tomography is inaccurate in estimating the severity of adult splenic injury.

Computed tomography (CT) is increasingly utilized in evaluation of adult splenic injury (SI). CT correlation with operative findings, CT relationship to successful nonoperative (NO) management, and CT reading reproducibility were examined. Records of patients > or = 15 years old admitted over a 3-year period were reviewed.

Tracheostomy and percutaneous endoscopic gastrostomy in the management of the head-injured trauma patient.

Forty-three trauma patients underwent tracheostomy (TRACH) and percutaneous endoscopic gastrostomy (PEG) over 21 months. Thirty-one patients had a head injury with Abbreviated Injury Scale > or = 3 associated with multi-trauma. This study was undertaken to analyze demographic and outcome variables with respect to timing of TRACH/PEG in this population.
