Background There is increasing interest in the use of noninvasive biomarkers to reduce the risks posed by invasive biopsy for monitoring of solid organ transplants (SOT). One such promising marker is the presence of donor-derived cell-free DNA (dd-cfDNA) in the urine or blood of transplant recipients. Methods We systematically reviewed the published literature investigating the use of cfDNA in monitoring of graft health following SOT. Electronic databases were searched for studies relating cfDNA fraction or levels to clinical outcomes, and data including measures of diagnostic test accuracy (DTA) were extracted. Narrative analysis was performed. Results 95 manuscripts from 47 studies met the inclusion criteria (18 kidney, 7 liver, 11 heart, 1 kidney-pancreas, 5 lung, and 5 multiorgan). The majority were retrospective and prospective cohort studies, with 19 reporting DTA data. Multiple techniques for measuring dd-cfDNA were reported, including many not requiring a donor sample. dd-cfDNA falls rapidly within 2 weeks, with baseline levels varying by organ type. Levels are elevated in the presence of allograft injury, including acute rejection (AR) and infection, and return to baseline following successful treatment. Elevation of cfDNA levels are seen in advance of clinically apparent organ injury. Discriminatory power was greatest for higher grades of T cell mediated and antibody-mediated AR, with high negative predictive values. Conclusions cfDNA is a promising biomarker for monitoring the health of solid-organ transplants. Future studies will need to define how it can be used in routine clinical practice and determine clinical benefit with routine prospective monitoring.

A worldwide survey of Live liver donor selection policies at 24 centers with a combined experience of 19 009 adult living donor liver transplants
Background While surgical technique in LDLT has evolved with a focus on donor safety and recipient challenges, the donor selection criteria remain considerably disparate. Methods A questionnaire on donor selection was sent to 41 centers worldwide. 24 centers with a combined experience of 19009 LDLTs responded. Results Centers were categorized into predominantly LDLT (18) or DDLT (6), and high (10) or low volume (14) centers. At the majority of centers, the minimum acceptable GRWR was 1 features of metabolic syndrome. On biopsy, all considered macrovesicular and 50% considered microvesicular steatosis important. Nearly all (92%) rejected donors for early fibrosis, and minority for nonspecific granuloma or mild inflammation. Most anatomical anomalies except portal vein type D/E were acceptable at high volume centers. There was no standard policy for pre or peroperative cholangiogram. Conclusions This first large live liver donor survey provides insight into donor selection practices that may aid standardization between centers, with potential expansion of the donor pool without compromising safety.

Lichen planus and lichenoid dermatoses
Deriving from the Greek word λειχήν for "tree moss" and the Latin word planus for "planar," lichen planus is a relatively uncommon and heterogeneous cutaneous disorder that typically develops in middle-aged adults. Despite the significant clinical burden associated with the disorder, little well-conducted molecular research has been undertaken, possibly because of heterogeneity impeding consistent and confident phenotyping. The multiple variants of lichenoid disease bear overlapping clinical and pathologic features despite manifesting as distinct clinical disorders.

Occurrence of aflatoxins in rice and in cassava ( Manihot esculenta ) products (meal, bread) produced in Guyana
Abstract
A survey was conducted on Guyana's main staple foods, rice, cassava meal and cassava bread to determine the presence and concentration of aflatoxins (AFs) using enzyme-linked immunosorbent assay (ELISA) and high-performance liquid chromatography (HPLC) with fluorescence detection for concurrence. Aflatoxins are secondary metabolites of the fungus Aspergillus and can be a health risk to humans and animals. Results were compared with European Union Commission (EUC) maximum levels of total aflatoxins of 10 μg/kg. Various types of rice (paddy, steamed paddy, cargo rice, white rice and parboiled rice) were randomly collected either directly from the field and rice mills in Guyana during the November 2015/March 2016 season. Of the total 186 composite samples of rice fractions collected from field and mills, 10% (19) had AF concentrations greater than the maximum EUC level of 10 μg/kg. Fifteen samples had aflatoxin concentrations ranging from 10 to 171 μg/kg, mean 54.4 μg/kg; four samples were outliers. Since Guyanese consume mainly white and parboiled rice, composite samples were taken along the marketing chain at points of sale to determine the presence of AFs. Of the sixty samples of white rice collected, 6.7% (4) had AF concentrations greater than the EUC regulatory limits ranging from 31.9 to 131 μg/kg, mean 80.8 μg/kg. For the 57 samples of parboiled rice, 3.5% (2) samples exceeded the limit with values of 72.6 and 407 μg/kg. Forty (40) samples each of cassava meal and cassava bread were analysed fresh and after 2 months of storage, and no sample exceeded the ELISA detection limit of 0.5 μg/kg.

Soluble CTLA-4 as a favorable predictive biomarker in metastatic melanoma patients treated with ipilimumab: an Italian melanoma intergroup study
Abstract
CTLA-4 blockade by means of ipilimumab (IPI) potentiates the immune response and improves overall survival (OS) in a minority of metastatic melanoma (MM) patients. We investigated the role of soluble CTLA-4 (sCTLA-4) as a possible biomarker for identifying this subset of patients. sCTLA-4 levels were analyzed at baseline in sera from 113 IPI-treated MM patients by ELISA, and the median value (200 pg/ml) was used to create two equally sized subgroups. Associations of sCTLA-4 with best overall response (BOR) to IPI and immune-related adverse events (irAEs) were evaluated through logistic regression. Kaplan–Meier and Cox regression methods were used to analyze OS. A remarkable association between sCTLA-4 levels and BOR was found. Specifically, the proportion of patients with sCTLA-4 > 200 pg/ml in irSD or irPD (immune-related stable or progressive disease) was, respectively, 80% (OR = 0.23; 95%CL = 0.03–1.88) and 89% (OR = 0.11; 95%CL = 0.02–0.71) and was lower than that observed among patients in irCR/irPR (immune-related complete/partial response). sCTLA-4 levels increased during IPI treatment, since the proportion of patients showing sCTLA > 200 pg/ml after 3 cycles was 4 times higher (OR = 4.41, 95%CL = 1.02–19.1) than that after 1 cycle. Moreover, a significantly lower death rate was estimated for patients with sCTLA-4 > 200 pg/ml (HR = 0.61, 95%CL = 0.39–0.98). Higher baseline sCTLA-4 levels were also associated with the onset of any irAE (p value = 0.029), in particular irAEs of the digestive tract (p value = 0.041). In conclusion, our results suggest that high sCTLA-4 serum levels might predict favorable clinical outcome and higher risk of irAEs in IPI-treated MM patients.

Empirical Proton Pump Inhibitor Therapy
For over a decade, publications in medical literature have raised several concerns regarding the use of proton pump inhibitors (PPIs). More recently, the pace of publication has quickened. This class of medications has been associated with pulmonary and gastrointestinal negative effects both in adults and children. For children, concern exists regarding elevated rates of viral and bacterial infections of the gastrointestinal tract, including Clostridium difficile, as well as increases in bacterial pneumonia. Changes in the microbiome may be related to these negative effects, and the length of PPI use may not matter. Although these concerns have been raised through studies that demonstrate correlation rather than cause and effect, word is getting out in gastroenterology, pediatrics, and neonatology. These findings have spread more slowly to those closely related fields of pulmonology and otolaryngology. These are fields in which physicians may be very comfortable and familiar with prescribing this class of medications to their pediatric patients, yet may be less aware of possible adverse effects than gastroenterologists and pediatricians.

The clinical value of assays detecting antibodies against domain I of β2-glycoprotein I in the antiphospholipid syndrome
Publication date: Available online 11 October 2018
Source: Autoimmunity Reviews
Author(s): Dongmei Yin, Bas de Laat, Katrien M.J. Devreese, Hilde Kelchtermans
Abstract
As the clinical symptoms of the antiphospholipid syndrome (APS) frequently occur irrespective of the syndrome, diagnosis predominantly depends on the laboratory assays measuring the level or function of antiphospholipid antibodies (aPLs). β2-glycoprotein I (β2GPI) is increasingly accepted as the most important target of aPLs. Anti-β2GPI antibodies constitute a heterogeneous population, but current in vivo and in vitro evidence show that especially the first domain (DI) of β2GPI contains an important pathogenic epitope. This epitope containing Glycine40-Arginine43 (G40-R43) has proven to be cryptic and only exposed when β2GPI is in its open conformation. A previous study demonstrated a highly variable exposure of the cryptic epitope in commercial anti-β2GPI assays, with implications on correct patient classification. Unexpectedly, recent unpublished data revealed impaired exposure of the pathogenic epitope in the commercially available anti-DI chemiluminescence immunoassay (CIA) assay detecting specific antibodies directed to DI.
In this review we summarize the laboratory and clinical performance characteristics of the different anti-DI assays in published data and conclude with inconsistent results for both the correlation of anti-DI antibodies with clinical symptoms and the added value of anti-DI antibodies in the classification criteria of APS. Additionally, we hypothesize on possible explanations for the observed discrepancies. Finally, we highly advise manufacturers to use normal pooled plasma spiked with the monoclonal anti-DI antibodies to verify correct exposure of the cryptic epitope.

Abstract
Objective
Because the impact of conditioned fear stress on apical bone resorption is unknown, the aim of the current studywas to use a rat model to evaluate the impact of conditioned fear stress on the bone resorption of inflammatory apical periodontitis lesions.
Methods
Twenty-five animals were divided into two groups. They underwent a surgical procedure in the first left lower molar tooth to expose the dental pulp and induce inflammatory apical periodontitis lesions through the retention of contamination (bacterial infection) during a 56-day period. The animals in the case group were stressed daily by using electrical stimuli (1.10 mA), whereas the animals in the control group were absent from the stressful stimuli (shocks). The open field test was performed to validate the stress methodology. The jaws were removed and collected for histological and radiographic analyses.
Results
Stressed animals presented increased levels of bone loss and inflammatory cells in the root apex in comparison with the control group (P = 0.0001). However, no radiographic differences were observed between the groups (P > 0.05).
Conclusions
Our results demonstrated that conditioned fear stress could modify a periapical lesion by increasing the size of bone loss there. Conditioned fear stress also increased the total number of inflammatory cells compared with the control group. Studies evaluating the impact of conditioned fear stress on human periapical inflammatory lesions should be encouraged.

Compensatory interactions between developing maxillary anterior teeth in a sample of twins
Publication date: Available online 10 October 2018
Source: Archives of Oral Biology
Author(s): Marianne Tadros, Alan H Brook, Sarbin Ranjitkar, Grant C Townsend
Abstract
Objectives
The objective of this study was to revisit the topic of compensatory interactions between maxillary anterior teeth during development advanced by Sofaer et al. (1971). We addressed the hypotheses listed by Sofaer and colleagues using data derived from our Australian twin sample to investigate whether final tooth size in permanent maxillary central incisors and canines showed evidence of developmental compensation for adjacent missing or microdont lateral incisors. Such compensation is one factor interacting in the complex system of dental development.
Materials and methods
A 2D image analysis system was used to measure crown height from the labial view, labiopalatal crown width from the incisal view, and mesiodistal crown width from both the labial (MDl) and incisal (MDi) views of the permanent maxillary central incisors and canines on the dental study model of twins enrolled in a longitudinal study of dental development.
Results
Developmental variations of maxillary lateral incisors influence the morphogenesis of the adjacent teeth. For example, individuals with one missing lateral incisor and one lateral incisor of average dimensions, had significantly larger central incisors than the control group for the MDl and MDi dimensions (p < 0.05). Of the 7 monozygotic twin pairs, 6 were discordant in maxillary anterior hypodontia and microdontia, and 13 out of 14 dizygotic twin pairs were discordant.
Conclusions
This study provides further evidence of developmental interactions in the maxillary anterior region, partially supporting Sofaer and colleagues' hypotheses. These interactions are part of a complex adaptive system involving genetic, epigenetic and environmental factors.

microRNA-199a may be involved in the pathogenesis of lupus nephritis via modulating the activation of NF-κB by targeting Klotho
Publication date: November 2018
Source: Molecular Immunology, Volume 103
Author(s): Hong Ye, Bofeng Su, Haizhen Ni, Linlin Li, Xuduan Chen, Xiaohan You, Huidi Zhang
Abstract
Klotho is considered to have renal protective effect by prohibiting the activation of the nuclear factor (NF)-κB pathway, while the role of microRNA-199a (miR-199a)/Klotho in lupus nephritis (LN) is still unknown. A single dose of pristane (0.5 ml) was intraperitoneally injected into 8 weeks-old female mice to establish the LN model. MiR-199a mimic or miR-199a inhibitor, Klotho plasmid or Klotho siRNA, and miR-199a inhibitor plus si-Klotho were transfected into lipopolysaccharides (LPS) stimulated human embryonic kidney 293 T (HEK293 T) cells. Western Blot was adopted to measure p-P65 expression. Tumor necrosis factor (TNF)-α and interleukin (IL)-1β in the supernatant were determined by enzyme-linked immunosorbent assay (ELISA). The expression of Klotho was suppressed by miR-199a through direct binding to the three prime untranslated regions (3'-UTR). The high miR-199a level was accompanied by low Klotho expression in the LN kidney. MiR-199a promoted LPS-induced NF-κB activation and improved the secretion of TNF-α and IL-1β by regulation of Klotho in HEK293 T cells. If miR-199a antagomir was administrated after 48 h of pristane administration, the expression of p-P65 and the secretion of TNF-α and IL-1β were significantly down-regulated in LN kidney. Although the direct involvement and detailed mechanism of miR-199a in LN still need further investigation, our data show that MiR-199a could regulate the activation of NF-κB by directly targeting Klotho.

Author(s): Rena Hirani, Melinda M. Dean, Zsolt J. Balogh, Natalie J. Lott, Julie Seggie, Jeremy M. Hsu, Susan Taggart, Peter Maitz, Lesley Survela, Anthony Joseph, Mark Gillett, David O. Irving
Abstract
Background
The potential for the co-existence of genetically disparate cells (microchimerism) and associated cytokine profiles following red blood cell (RBC) transfusion in trauma patients has not been well characterized to date. This study investigated the incidence of surviving donor white blood cells (known as transfused-associated microchimerism (TAM)) and cytokine changes following blood transfusion in trauma patients.
Study design and methods
Trauma patients with an injury severity score (ISS) >12 who had been transfused between 2012–2016 with at least 5 units of RBC units over a 4 h period were recruited. Trauma patients with ISS > 12 who did not require blood transfusion were recruited as controls. The incidence of TAM was determined using a panel of insertion/deletion (InDel) bi-allelic polymorphisms. Selected pro- and anti-inflammatory cytokine profiles were analyzed using cytometric bead array.
Results
The transfused cohort (n = 40) had median ISS of 28 [12–66], received a median of 11 RBC units [4–114] and had median hospital length of stay of 35 days [1–152]. Only 11 (27.5%) patients returned for follow-up blood sampling after discharge. Of these, one patient showed an InDel pattern indicating the presence of TAM. No patients in the control cohort (n = 49) showed TAM. Cytokines IL-10 and IL-6 were found to be elevated in the transfused trauma patients.
Conclusion
In this cohort, TAM was found to occur in one patient of the 11 who received a blood transfusion. Elevated IL-6 and IL-10 cytokines were detected in those patients who were transfused. However, the incidence of TAM could not be correlated with the elevated cytokine profiles for this cohort.

Abstract
The central component of the complement cascade, C3, is involved in various biological functions, including opsonization of foreign bodies, clearance of waste material, activation of immune cells, and triggering of pathways controlling development. Given its broad role in immune responses, particularly in phagocytosis and the clearance of microbes, a deficiency in complement C3 in humans is often associated with multiple bacterial infections. Interestingly, an increased susceptibility to infections appears to occur mainly in the first two years of life and then wanes throughout adulthood. In view of the well-established connection between C3 deficiency and infections, therapeutic inhibition of complement at the level of C3 is often considered with caution or disregarded. We therefore set out to investigate the immune and biochemical profile of non-human primates under prolonged treatment with the C3 inhibitor compstatin (Cp40 analog). Cynomolgus monkeys were dosed subcutaneously with Cp40, resulting in systemic inhibition of C3, for 1 week, 2 weeks, or 3 months. Plasma concentrations of both C3 and Cp40 were measured periodically and complete saturation of plasma C3 was confirmed. No differences in hematological, biochemical, or immunological parameters were identified in the blood or tissues of animals treated with Cp40 when compared to those injected with vehicle alone. Further, skin wounds showed no signs of infection in those treated with Cp40. In fact, Cp40 treatment was associated with a trend toward accelerated wound healing when compared with the control group. In addition, a biodistribution study in a rhesus monkey indicated that the distribution of Cp40 in the body is associated with the presence of C3, concentrating in organs that accumulate blood and produce C3. Overall, our data suggest that systemic C3 inhibition in healthy adult non-human primates is not associated with a weakened immune system or susceptibility to infections.

Abstract
Background
IgG4 production is regulated by type 2 (IL-4 and IL-13) and regulatory (IL-10) cytokines involved in the pathophysiology of chronic rhinosinusitis (CRS). We sought to determine the pathophysiological characteristics of IgG4-positive cells in sinonasal tissues in CRS, especially eosinophilic CRS (ECRS).
Methods
IgG4-positive cells in uncinate tissues (UT) and nasal polyps (NP) were examined by immunohistochemistry. Associations between the number of IgG4-positive cells and clinicopathological factors were analyzed. Receiver operating characteristics (ROC) analysis was performed to determine the cut-off value of IgG4-positive cells in tissue that can predict the post-operative course.
Results
IgG4 was mainly expressed in infiltrating plasma and plasmacytoid cells, and the number of IgG4-positive cells was significantly higher in NP, especially those from severe ECRS patients, than in UT. In CRS patients, the number of IgG4-positive cells significantly and positively correlated with blood and tissue eosinophilia, radiological severity, and serum level of total IgE. The number of infiltrating IgG4-positive cells was significantly higher in patients with a poor post-operative course (sustained sinus shadow 6 months after surgery) than in those with a good one. The number of IgG4-positive cells in NP could discriminate patients with a good or a poor post-operative course (area under the curve: 0.769). Also, 73.3% sensitivity and 82.5% specificity were achieved when the cut-off value was set at 17 cells/high-power field.
Conclusions
Our results suggest that the local expression of IgG4 on cells may be used as a biomarker that reflects the pathophysiology of CRS, including the post-operative course.

Complete unilateral ureteral duplication encountered during intersphincteric resection for low rectal cancer
Abstract
Complete duplication of ureters is a very rare clinical entity that may either be asymptomatic or present with a variety of clinical findings. In the presented case a 51-year-old Caucasian female underwent an intersphincteric resection for low rectal cancer. Intraoperatively, during the standard bilateral recognition and mobilization of the ureters, complete unilateral duplication of the left ureter was incidentally detected, deriving from a single renal parenchyma. Such a congenital abnormality though constitutes a major risk-factor of accidental ureteral injury during operations including pelvis. Conclusively, meticulous exposure of both ureters combined with surgeons' unceasing awareness constitute the cornerstone of a safe operation.https://ift.tt/2QHHs6A
High-grade angiosarcoma presenting with cytology-negative hemorrhagic ascites
Abstract
Angiosarcomas are a rare subtype of soft-tissue sarcomas originating from the vascular endothelium. Both retroperitoneal and omental angiosarcomas tend to be aggressive and rapidly fatal if not amenable to early intervention. In this report, we describe an unusual case of high-grade angiosarcoma with cytology-negative hemorrhagic ascites and diffuse omental invasion. Multiple investigations into the origin of the hemorrhagic ascites, including cytological analysis, tumor marker measurements, serum-ascites albumin gradient calculation and frozen section pathological examination, failed to reveal a diagnosis. We conclude that malignancy should be considered in the differential diagnosis in the presence of suspicious cytology-negative hemorrhagic ascites and concomitant retroperitoneal and abdominal findings.https://ift.tt/2A4j21y
Distraction osteogenesis for brachymetatarsia using initial circular fixator and early trans-fixation metatarsal K—wires—a series of three cases†
Abstract
Brachymetatarsia is a rare forefoot deformity predominantly affecting the fourth metatarsal. Current treatment include gradual lengthening by distraction osteogenesis using an external fixator or single-stage lengthening with bone grafting or a combination of the above two procedures. Our aim was to assess outcomes and complications of a novel technique for gradual metatarsal lengthening using a circular fixator. The procedure was performed on three female patients with unilateral congenital shortening of the fourth ray. All participants reported aesthetic dissatisfaction as well as pressure related complications of the deformity and opted for lengthening and distraction osteogenesis using a frame. Mean duration of the treatment was 122 days and average length gained was 12 mm. The desired metatarsal length was achieved in all three patients with no significant complications.

Advances in mechanisms of allergic disease 2017
Publication date: Available online 11 October 2018
Source: Journal of Allergy and Clinical Immunology
Author(s): Chrysanthi Skevaki, Harald Renz
Abstract
This review highlights advances in mechanisms of allergic disease, particularly type 2 innate lymphoid cells; TH2 lymphocytes; B cells; dendritic cells: microbiome and barrier function; eosinophils, mast cells. During the last year, considerable progress has been made in the further characterization of type 2 inflammation controlled by both adaptive (TH2) as well as innate (ILC2) effector cells. New pathways of lymphocyte activation, trafficking and recruitment, and effector cell mechanisms have been discovered. The plasticity of lymphocyte effector cell responses is another area where major progress has been achieved. Accumulating evidence will influence both our understanding of allergic disease but also our efforts for allergy prevention and treatment.

Neuroplastic changes in the olfactory bulb associated with nasal inflammation in mice
Publication date: Available online 10 October 2018
Source: Journal of Allergy and Clinical Immunology
Author(s): Sanae Hasegawa-Ishii, Atsuyoshi Shimada, Fumiaki Imamura
Abstract
Background
Rhinitis and rhinosinusitis are olfactory disorders caused by inflammation of the nasal passage and paranasal sinuses. Although chronic rhinosinusitis patients have smaller olfactory bulbs (OBs), there is limited knowledge regarding the influence of chronic nasal inflammation on OB neurons.
Objective
Repeated intranasal administration of lipopolysaccharide (LPS) that induced persistent nasal inflammation in mice caused a loss of olfactory sensory neurons (OSNs) and gliosis and synaptic loss in the OB within three weeks. The present study aimed to clarify the effects of long-term LPS treatment on the OB neurocircuit.
Methods
LPS was repeatedly administered into a mouse nostril for up to 24 weeks. For the recovery analyses, the mice received LPS for 10 weeks and were subsequently maintained without additional treatment for another 10 weeks. The effects of these treatments on the OB were histologically examined. Three or more mice were analyzed per group.
Results
Long-term repeated LPS administration caused OB atrophy, particularly in the layers along which OSN axons travel and in the superficial external plexiform layer (sEPL), in which tufted cells form synapses with interneurons. Interestingly, the OB recovered from atrophy following the cessation of LPS administration: the OB volume and sEPL thickness returned to the pretreatment level after the nontreatment period. In contrast, the regeneration of OSN was incomplete.
Conclusion
These results suggest that chronic nasal inflammation induces structural changes in a specific OB circuit related to tufted cells, while tufted cells retain a high degree of plasticity that enables recovery from structural damages after inflammation subsides.

Abstract
Introduction/objective
Oral and oropharyngeal mucositis (OM) represents a multifactorial and complex interplay of patient-, tumor-, and treatment-related factors. We aimed to build a predictive model for acute OM for locally advanced nasopharyngeal carcinoma (NPC) patients by combining clinical and dosimetric factors.
Materials/methods
A series of consecutive NPC patients treated curatively with IMRT/VMAT + chemotherapy at 70 Gy (2–2.12 Gy/fr) was considered. For each patient, clinical- tumor- and treatment-related data were retrospectively collected. oral cavity (OC) and parotid glands (PG, considered as a single organ) were selected as organs-at-risk (OARs). Acute OM was assessed according to CTCAE v4.0 at baseline and weekly during RT. Two endpoints were considered: grade ≥3 and mean grade ≥1.5. DVHs were reduced to Equivalent Uniform Dose (EUD). Dosimetric and clinical/treatment features selected via LASSO were inserted into a multivariable logistic model. Goodness of fit was evaluated through Hosmer-Lemeshow test and calibration plot.
Results
Data were collected for 132 patients. G ≥ 3 and mean G ≥ 1.5 OM were reported in 40 patients (30%). Analyses resulted in a 3-variables model for G ≥ 3 OM, including OC EUD with n = 0.05 (OR = 1.02), PG EUD with n = 1 (OR = 1.06), BMI ≥ 30 (OR = 3.8, for obese patients), and a single variable model for mean G ≥ 1.5 OM, i.e. OC EUD with n = 1 (mean dose) (OR = 1.07). Calibration was good in both cases.
Conclusion
OC mean dose was found to impact most on OM duration (mean G ≥ 1.5), while G ≥ 3 OM was associated to a synergic effect between PG mean dose and high dose received by small OC volumes, with BMI acting as a dose-modifying factor.

A novel scoring model to predict benefit of additional induction chemotherapy to concurrent chemoradiotherapy in stage II–IVa nasopharyngeal carcinoma
Publication date: November 2018
Source: Oral Oncology, Volume 86
Author(s): Liang Peng, Yu-Pei Chen, Cheng Xu, Ling-Long Tang, Lei Chen, Ai-Hua Lin, Xu Liu, Ying Sun, Jun Ma
Abstract
Objectives
Induction chemotherapy (IC) is gaining recognition for the treatment of nasopharyngeal carcinoma (NPC). We aimed to develop a model to predict benefit from additional IC to concurrent chemoradiotherapy (CCRT).
Materials and methods
From an NPC-specific database, 7413 patients with stage II–IVa disease who received CCRT with or without IC were included. Distant metastasis-free survival (DMFS) was the primary outcome and benefit from IC was evaluated by adjusted hazard ratio. Interaction terms between IC and other prognostic factors were identified in multivariate Cox model, and IC benefit score (ICBS) was calculated based on β coefficients from the Cox model.
Results
Nodal category, overall stage, and pre-treatment plasma Epstein–Barr virus DNA (log transformed as continuous variable) interacted with IC and determined ICBS. ICBS could discriminate patients who benefited differently from IC in terms of DMFS well, especially for patients with high and low ICBS. As for patients with medium ICBS, predictive performance of ICBS seemed reduced.
Conclusions
Based on the ICBS model, we proposed a decision-making process to help in clinical practice. Multi-institutional and prospective studies are warranted to further validate our findings.

Abstract
Background
Few studies on the age of resolution of Food Protein Induced Enterocolitis Syndrome (FPIES) induced by solid foods are available. In particular, for FPIES induced by egg, the mean age of tolerance acquisition reported in the literature ranges from 42 to 63 months.
Objective
We have assessed whether the age of tolerance acquisition in acute egg FPIES varies depending on whether the egg is cooked or raw.
Methods
We conducted a retrospective and multicentric study of children with diagnosis of acute egg FPIES seen in 10 Italian allergy units between July 2003 and October 2017. The collected data regarded sex, presence of other allergic diseases, age of onset of symptoms, kind and severity of symptoms, cooking technique of the ingested egg, outcome of the allergy test, age of tolerance acquisition.
Results
Sixty-one children with acute egg FPIES were enrolled, 34 (56%) males and 27 (44%) females. Tolerance to cooked egg has been demonstrated by 47/61 (77%) children at a mean age of 30.2 months. For 32 of them, tolerance to raw egg has been demonstrated at a mean age of 43.9 months. No episodes of severe adverse reaction after baked egg ingestion have been recorded.
Conclusions
It is possible to perform an OFC with baked egg, to verify the possible acquisition of tolerance, at about 30 months of life in children with acute egg FPIES.

Focus group parental opinions regarding treatment with topical corticosteroids on children with atopic dermatitis
Publication date: Available online 10 October 2018
Source: Allergologia et Immunopathologia
Author(s): S. Veenje, H. Osinga, I. Antonescu, B. Bos, T.W. de Vries
Abstract
Introduction and objectives
Atopic dermatitis is common among children of 0–5 years old. Treatment consists of emollients and topical corticosteroids. Due to corticophobia, however, adherence to topical corticosteroids is low. Our aim was to find factors that influence opinions about topical corticosteroids among parents of children with atopic dermatitis.
Methods
A qualitative focus group study in secondary care with parents of children with atopic dermatitis. Questions concerned opinions, attitude, sources of information, and the use of topical corticosteroids.
Results
The parents indicated that they lack knowledge about the working mechanism and side effects of topical corticosteroids. Dermatologists and paediatricians emphasise the beneficial effects, whereas other healthcare workers and lay people often express a negative attitude.
Conclusions
This study gives a complete overview of factors influencing adherence. Treatment with topical corticosteroids can be improved by better informing parents about the working mechanisms, the use, and how to reduce the dose. Healthcare professionals need to be aware of the consequences of their negative attitude concerning topical corticosteroids.

Development of a Donor Tissue Holding Technique for Descemet’s Membrane Endothelial Keratoplasty Using a 25-Gauge Graft Manipulator
Purpose: To report a modified surgical technique called the "donor tissue holding technique for Descemet's membrane endothelial keratoplasty (DMEK)" using a newly developed 25-gauge graft manipulator. Methods: Six consecutive patients exhibiting endothelial dysfunction were enrolled and treated by DMEK. In brief, after insertion of a DMEK donor into the anterior chamber, the edge of the roll was grasped using a graft manipulator and this grasp was maintained throughout the centering and opening of the roll (holding technique). The following parameters were evaluated in comparison to the previous 10 consecutive DMEK cases in which the no touch technique was used: time of graft unfolding, incidence of intra-/postoperative complications, and best spectacle-corrected visual acuity (BCVA) and endothelial cell density (ECD) 6 months after the procedure. Results: In both technique groups, neither intra- nor postoperative complications were noted in any case. No differences were observed between the two groups in postoperative BCVA (p = 0.88). Also, no differences were observed between the two groups in postoperative ECD (holding technique group: 2,108.3 cells/mm2, no touch technique group: 1,491.7 cells/mm2) (p = 0.08) Most notably, the time of graft unfolding prior to filling with air was significantly reduced in the holding technique group (305.5 s) compared to that of the no touch technique group (1,310.0 s; p = 0.01). Conclusions: This donor tissue holding technique enabled rapid and safe DMEK in a reproducible manner, even in Asian eyes with shallow anterior chambers with high vitreous pressure.

CIC fusion-positive sarcoma of the spermatic cord
Abstract
In addition to germ cell tumors and tumors of the sex cord stroma, the WHO classification of testis and paratesticular tumors also contains malignant soft tissue tumors. Among them, liposarcomas of the spermatic cord are the most common entities. Other mesenchymal tumors with smooth muscle, skeletal muscle, fibroblastic/myofibroblastic, or nerve sheath differentiation are rare. Ewing sarcoma is composed of uniform small round cells and typically characterized by translocations of the EWSR1 gene. In rare cases, Ewing sarcoma-like tumors lack an EWSR1 gene fusion. Some of these tumors harbor a specific CIC translocation. However, Ewing-like sarcoma has up to now never been described in the testis or spermatic cord. The present case describes the first EWSR1-negative, undifferentiated round cell sarcoma with CIC translocation of the spermatic cord. Potential differential diagnoses are discussed.

Bilateral suprazygomatic maxillary nerve blocks vs. infraorbital and palatine nerve blocks in cleft lip and palate repair: A double-blind prospective, randomised study
BACKGROUND Cleft defects are common craniofacial malformations which require early surgical repair. These patients are at high risk of postoperative airway obstruction and respiratory failure. Cleft surgery may require high doses of opioids which may contribute to these complications. OBJECTIVES To compare the effectiveness of proximal and distal approaches to blocking the maxillary nerve in patients undergoing cleft lip or cleft palate surgery. DESIGN Randomised, controlled and double-blind study. SETTING The current study was carried out in Guwahati (Assam, India) between April 2014 and June 2014. PATIENTS A total of 114 patients older than 6 months who underwent cleft lip or cleft palate surgery were included. Exclusion criteria included coagulation disorders, peripheral neuropathy or chronic pain syndrome, infection in the puncture site, allergy to local anaesthetics, lack of consent and language problems or other barriers that could impede the assessment of postoperative pain. INTERVENTIONS Patients were randomly assigned to one of two groups: proximal group (bilateral suprazygomatic maxillary nerve blocks) and distal group (bilateral infraorbital nerve blocks for cleft lip repair and bilateral greater and lesser palatine nerve blocks and nasopalatine nerve block for cleft palate surgery). MAIN OUTCOME MEASURE The primary endpoint was the percentage of patients requiring extra doses of opioids. Secondary endpoints included pain scores, respiratory and nerve block-related complications during the first 24 h. RESULTS In the intra-operative period, there was a significant reduction of nalbuphine consumption in the proximal group (9.1 vs. 25.4%, P = 0.02). The percentage of patients requiring intra-operative fentanyl was lower in the proximal group (16.4 vs. 30.5%, P = 0.07). There were no differences in either postoperative pain scores or in postoperative complications. No technical failure or block-related complications were reported. CONCLUSION Bilateral suprazygomatic maxillary nerve block is an effective and safe alternative to the traditional peripheral nerve blocks for cleft lip and cleft palate surgery, in a mixed paediatric and adult population.

Measurement of forces applied using a Macintosh direct laryngoscope compared with a Glidescope video laryngoscope in patients with predictors of difficult laryngoscopy: A randomised controlled trial
BACKGROUND In patients with predictive features associated with easy direct laryngoscopy, videolaryngoscoy with the GlideScope has been shown to require less force when compared with Macintosh direct laryngoscopy. OBJECTIVE The aim of this study was to compare forces applied with Glidescope vs. Macintosh laryngoscopes in patients with predictive features associated with difficult direct laryngoscopy. DESIGN A prospective randomised study. SETTING Toronto General Hospital, a university tertiary centre in Canada. PATIENTS Forty-four patients aged over 18 years, with one or more features of difficult intubation, undergoing elective surgery requiring single-lumen tracheal intubation. INTERVENTION We measured the force applied to oropharyngeal tissues by attaching three FlexiForce Sensors (A201-25) to the concave surface of Macintosh and GlideScope laryngoscope blades. Anaesthetists or experienced anaesthesia residents performed laryngoscopies with both devices in a randomised sequence. MAIN OUTCOME MEASURES The primary outcome was peak force. The secondary outcomes were average force and impulse force. The latter is the integral of the force over the time during which the force acted. RESULTS Complete data were available for 40 individuals. Peak and average forces decreased with GlideScope (17 vs. 21 N, P = 0.03, and 6 vs. 11 N, P

Modified ROTEM for the detection of rivaroxaban and apixaban anticoagulant activity in whole blood
BACKGROUND Rapid detection of the anticoagulant effect of oral factor Xa (FXa) inhibitors may be essential in several emergency clinical situations. Specific assays quantifying the drugs are performed in plasma and require a turnaround time that is too long to be useful in emergency situations. Rotational thromboelastometry (ROTEM) is a whole blood coagulation assay of blood viscoelasticity and could be of interest for FXa inhibitor detection in emergency. However, conventional ROTEM reagents only detect high amounts of inhibitors. OBJECTIVE The aim of this study was first to assess the effect of whole blood components on the viscoelastic measurement of the effects of FXa inhibitors, an second to evaluate whether a modified ROTEM, triggered with a low amount of tissue factor and a saturating amount of phospholipid vesicles, can reliably detect low levels of FXa inhibitor activity in whole blood. DESIGN Diagnostic test study. SETTINGS A university research laboratory. From November 2014 to April 2016. PATIENTS Sixty-six patients: 30 treated with rivaroxaban, 17 with apixaban and 19 without treatment. INTERVENTION ROTEM was triggered with 2.5 pmol l−1 of tissue factor and 10 μmol l−1 of phospholipid vesicles. MAIN OUTCOME MEASURES Modified ROTEM parameters were measured in different experimental conditions: platelet-poor plasma (PPP), platelet-rich plasma, PPP supplemented with fibrinogen and reconstituted whole blood with various haematocrit levels adjusted between 30 and 60%. Modified ROTEM was further validated using whole blood from patients who were either treated or not treated with FXa inhibitors. RESULTS Modified ROTEM allowed detection of as little as 25 ng ml−1 FXa inhibitors in PPP, with at least a 1.4-fold increase of the clotting time (P ≤ 0.02). Neither changes of fibrinogen concentration nor variations of platelet count or haematocrit precluded FXa inhibitor detection. A lengthened modified ROTEM clotting time of more than 197 s allowed detection of FXa inhibitor concentrations above 30 ng ml−1 in whole blood with 90% sensitivity and 85% specificity. CONCLUSION Modified ROTEM may be applicable in emergency situations for the detection of FXa inhibitors in whole blood. Correspondence to Charles M.

A scavenging system against internal pathogens promoted by the circulating protein apoptosis inhibitor of macrophage (AIM)
Abstract
An internal system designed to ward off and remove unnecessary or hazardous materials is intrinsic to animals. In addition to exogenous pathogens, a number of self-molecules, such as apoptotic or necrotic dead cells, their debris, and the oxides or peroxides of their cellular components, are recognized as extraneous substances. It is essential to eliminate these internal pathogens as quickly as possible because their accumulation can cause chronic inflammation as well as autoimmune responses, possibly leading to onset or progression of certain diseases. Apoptosis inhibitor of macrophage (AIM, also called CD5L) is a circulating protein that is a member of the scavenger receptor cysteine-rich superfamily, and we recently found that during acute kidney injury, AIM associates with intraluminal dead cell debris accumulated in renal proximal tubules and enhances clearance of luminal obstructions, thereby facilitating repair. Thus, AIM acts as a marker for phagocytes so that they can efficiently recognize and engulf the debris as their targets. In this chapter, we give an overview of the professional and non-professional phagocytes, and how soluble scavenging molecules such as AIM contribute to improvement of diseases by stimulating phagocytic activity.

Recurrent grade 4 panuveitis with serous retinal detachment related to nivolumab treatment in a patient with metastatic renal cell carcinoma
Abstract
Blockade of programmed cell death-1 (PD-1) has become one of the most promising immunotherapies for many human cancers. However, immune-related adverse events can be produced by anti-PD-1 therapy. Uveitis is a rare but potentially devastating side effect of anti-PD-1 therapy. Delay in diagnosis or improper treatment may eventually lead to irreversible blindness. Therefore, it is important for the oncologist and the ophthalmologist to recognize and manage this adverse event properly in patients receiving anti-PD-1 therapy in a timely manner. Here we present a grade 4 panuveitis with bilateral serous retinal detachment following treatment with nivolumab for metastatic renal cell carcinoma. Oral prednisone, topical steroid eye drops, periorbital injection of steroid and finally intravitreal injection of steroid implant were administered in our patient. We observed that intravitreal injection of dexamethasone implant, but not the periorbital injection of steroid or the steroid eye drops, was effective to control the posterior uveitis and serous retinal detachment. Oral prednisone was also effective, but it might affect the efficacy of anti-PD-1 therapy and promote tumor growth. We also summarize 15 cases of uveitis reported to date related to nivolumab or pembrolizumab therapy in the present study. The symptoms, signs, potential underlying mechanisms and treatment options regarding this adverse event are discussed.
