Abstract
Bronchiolar adenoma (BA) is a rare benign lung tumor that shows proliferation of bland bronchiolar-type epithelium containing a continuous layer of basal cells. This tumor entity has been newly added to the recent World Health Organization (WHO) classification 5th edition. This entity encompasses a spectrum of lesions: the classic ciliated muconodular papillary tumor (CMPT) and the non-classic CMPT. Although BA is reported to have driver mutations including BRAF V600E, EGFR, and KRAS, the molecular profile of BA is still incompletely understood. Five resected BAs at our institutions were analyzed. The BA lesions were subdivided into two groups: three proximal-type BAs and two distal-type BAs. NRAS codon 12/13 mutation and EML4 exon 20-ALK exon 20 fusion were found in two of the three proximal-types. BRAF V600E mutation was found in one of the two distal-types. Two cases coexisted with lung adenocarcinoma, with EGFR exon 19 deletion and KRAS mutation, respectively. No recurrence was observed at a median of 12 months (range 2-84 months) of follow-up. BA has uncommon variants of mutation seen in lung adenocarcinoma. NRAS mutation and ALK fusion partner has not been reported previously. The present cases may reinforce the distinctive biology of BA from lung adenocarcinoma.

Abstract
Abstract
Background
The diagnosis of acute (AM) is difficult because of the variable, unspecific clinical presentation. Cardiac magnetic resonance (CMR) is the noninvasive gold standard diagnostic tool, but limited availability and high costs make a quick and inexpensive test necessary to clarify the need for CMR. Quantification of high sensitive Troponin T (hsTNT) is a broadly available, specific blood test for cardiomyocyte damage.
Aim
The aim of this study was to evaluate hsTNT as a gatekeeper for CMR with a lower cut off-value for exclusion and an upper cut-off value for confirmation of acute myocarditis as defined by CMR.
Methods
This retrospective analysis included 244 patients (age 39±17 years, 71% male) who received CMR for clinically suspected AM and quantification of hsTNT within 28 days (Median: 2 days) of CMR. CMR (1.5 Tesla) consisted of cine-sequences, edema-sensitive T2 and late gadolinium enhancement (LGE) imaging. AM was diagnosed in presence of both, myocardial edema and LGE consistent with acute myocarditis.
Results
Of 244 patients, 78 (32%) were CMR-positive (CMR+) for AM. 166 (68%) were CMR negative (CMR−). Mean hsTNT was 206±454 pg/ml.
HsTNT was significantly higher in CMR+ than in CMR− (604±639 pg/ml vs 20±56 pg/ml, p<0.001, see figure A). 8 CMR+ patients (10%) had hsTNT in the normal range (<14 ng/ml).
HsTNT showed good discriminatory performance in the Receiver Operator Characteristic (ROC) analysis (AUC 0.91, see figure B).
A lower cut-off value of 4 pg/ml had a sensitivity of 98.7% for diagnosis of AM (hsTNT ≥4 pg/ml) and a negative predictive value of 98.2% for rule out of AM (hsTNT<4 pg/ml) as defined by CMR, leading to a reduction of 23.4% of CMR exams. An upper cut-off value of >343 pg/ml had a specificity of 99.4% and positive predictive value of 97.8% for diagnosis of AM, leading to a reduction of 18.4% of CMR exams (see table).
Conclusions
hsTNT showed good discriminatory capacity for acute myocarditis (AM) as defined by CMR. However, 10% of patients had hsTNT in the normal range (<14 pg/ml). A lower cut-off value of <4 pg/ml ruled out AM with very high negative predictive value, whereas an upper cut-off of >343 pg/ml had a very high positive predictive value for confirmation of AM as defined by CMR. Performing CMR only in patients with hsTNT between 4 and 343 pg/ml would have led to a reduction of 41.8% of CMR exams.

Abstract
Advanced granulocyte colony-stimulating factor (G-CSF)-producing lung tumours are generally refractory to platinum-based chemotherapy and are associated with poor prognosis. However, therapeutic strategies for these tumours remain unknown. A 74-year-old man was diagnosed with non-small cell lung cancer-not otherwise specified (NSCLC-NOS); the clinical stage was T4N0M1c stage IVb. Blood testing showed leucocytosis and aberrant G-CSF expression. We chose single-agent pembrolizumab as the initial treatment because PD-L1 was highly expressed in the tumours. A clinically favourable response was achieved from seven courses of pembrolizumab with a total disease-free survival of 10 months. During this period, the blood leucocyte count was concordant with the disease condition. These observations showed that pembrolizumab monotherapy may be an effective treatment for patients with advanced G-CSF-producing NSCLC-NOS and that the monitoring of leucocyte count may be a useful biomarker for predicting the efficacy of pembrolizumab monotherapy.

Abstract
BACKGROUND Total pancreatectomy is required to completely clear tumours that are locally advanced or located in the centre of the pancreas. However, reports describing clinical outcomes after total pancreatectomy are rare. The aim of this retrospective observational study was to assess clinical outcomes following total pancreatectomy using a nationwide registry and to create a risk model for severe postoperative complications. METHODS Patients who underwent total pancreatectomy from 2013 to 2017, and who were recorded in the Japan Society of Gastroenterological Surgery and Japanese Society of Hepato-Biliary-Pancreatic Surgery database, were included. Severe complications at 30 days were defined as those with a Clavien-Dindo grade III needing reoperation, or grade IV-V. Occurrence of severe complications was modelled using data from patients treated from 2013 to 2016, and the accuracy of the model tested among patients from 2017 using c-statistics and a calibration plot. RESULTS A total of 2167 patients undergoing total pancreatectomy were included. Postoperative 30-day and in-hospital mortality rates were 1·0 per cent (22 of 2167 patients) and 2·7 per cent (58 of 167) respectively, and severe complications developed in 6·0 per cent (131 of 2167). Factors showing a strong positive association with outcome in this risk model were the ASA performance status grade and combined arterial resection. In the test cohort, the c-statistic of the model was 0·70 (95 per cent c.i. 0·59 to 0·81). CONCLUSION The risk model may be used to predict severe complications after total pancreatectomy.

Abstract
Abstract
Objectives
Abnormal pulmonary perfusion due to stenosis of the central pulmonary arteries is common after neonatal arterial switch operation (ASO) for transposition of the great arteries (TGA). We conducted a monocentric prospective study in young adults after neonatal ASO for TGA to evaluate the effects of abnormal pulmonary perfusion on the increase of the right ventricular stroke volume (RVSV) during dobutamine stress magnetic resonance (DSMR) and on cardiopulmonary exercise capacity.
Methods
68 unselected patients (age 18–29 years) underwent CMR at rest and under dobutamine stress (10 to 40 μg/kg/min). RVSV, pulmonary blood flow distribution (PBFD) and peak flow velocity were derived from phase contrast mapping in the main, right and left pulmonary artery (PA) at rest and each stress level. A cardiopulmonary exercise test (CPET) was performed at the same day. All patients reached maximal exercise effort according to heart rate and respiratory exchange rate.
Results
PBFD at rest: 9/68 patients (13%, ASO-S) had abnormal pulmonary perfusion at rest, defined as PBFD >2:1 (right/left or left/right) and/or relevant stenosis of the main PA (Vmax >2.5 m/s). 59/68 patients (87%, ASO-N) had normal pulmonary perfusion.
PBFD under DSMR: (1) In the whole patient group, there was no increase of PBFD under stress compared to PBFD at rest. On an individual patient level, no relevant worsening of abnormal PBFD was found.
(2) Under low dose dobutamine, ASO-S had a significantly lower RVSV-increase (RVSVstress/RVSVrest) compared to ASO-N (see figure). However, under high dose dobutamine, this effect was no longer significant (see figure).
(3) The RVSV-increase under low and high dose dobutamine did not correlate with peak oxygen uptake during CPET, neither in the total group nor in the subgroups (see table). Peak oxygen uptake was not significantly different between ASO-N and ASO-S (p=0,72).
RVSV-increase compared to CPET peak VO2% ASO-total ASO-S ASO-N RVSV-increase/peak VO2% RVSV-increase/peak VO2% RVSV-increase/peak VO2% low dose dobu high dose dobu low dose dobu high dose dobu low dose dobu high dose dobu Pearson correlation coefficient −0.02 −0.05 0.01 −0.22 −0.05 −0.04 p-value 0.90 0.71 0.98 0.56 0.71 0.78
Figure 1
Conclusion
(1) Patients with relevant stenosis of main PA and/or abnormal peripheral blood flow distribution (ASO-S) exhibit a reduced RVSV-increase under low dose dobutamine compared to patients without stenosis (ASO-N). This effect was not present under high dose dobutamine stress.
(2) These findings did not correlate with peak oxygen uptake during CPET, an objective parameter of cardiopulmonary exercise capacity.
(3) Therefore, a conservative proceeding rather than surgery or catheter intervention should be considered, especially in asymptomatic adult patients.

Abstract
Osteo-odontokeratoprosthesis (OOKP) is a technique invented by Strampelli in 1963, in which the patient's own tooth root is used to support an optical cylinder. It uses an autologous tooth-bone-periodontal complex to mount an optical cylinder, which is stabilised by overlying autologous buccal mucosa. OOKP involves two, staged procedures done by ophthalmologists and oral surgeons, and the main contribution from the oral surgeon is during the first stage. To date we have done nine first-stage, and completed eight second-stage, OOKP operations in Japan with a mean follow-up of eight years and 11 months by modifying the original method of the oral surgery. All OOKP procedures were unilateral, and canines were selected as the donor teeth. Patients developed ocular blindness as a result of Stevens-Johnson syndrome, ocular cicatricial pemphigoid, and chemical and thermal burns to the cornea and ocular surface. All eight patients who completed the second stage have been stable, and there have been no major perioperative or postoperative oral complications. The patients' visual acuities were stable with no serious complications. Here we report the technical details of the oral contribution to OOKP.

Abstract
BACKGROUND To prevent leakage of pancreatic juice from the main pancreatic duct (MPD), complete external drainage appears to be the most effective technique. However, because this requires a pancreatic stent tube to be ligated with MPD, duct-to-mucosa pancreaticojejunostomy (PJ) is difficult. From our histopathological examination, a large amount of pancreatic juice is drained from the ducts other than MPD. This study aimed to evaluate our new conceptual technique of PJ after pancreaticoduodenectomy (PD). METHODS We considered it important to drain pancreatic juice from the branch pancreatic ducts to the intestinal tract and to perform duct-to-mucosa PJ, while pancreatic juice from MPD is completely drained out of the body. We designed a technique that could simultaneously achieve these points. In our technique, which is based on conventional "two-row" anastomosis, a stent tube is fixed with MPD and its surrounding tissue by purse-string suture at the cut surface of the pancreas, and duct-to-mucosa PJ is concomitantly performed. RESULTS Of 45 patients undergoing PD, 12 of soft pancreas underwent surgery with this technique. According to the classification of the International Study Group on Pancreatic Fistula, a Grade A PF was observed in four patients, whereas no patient had a Grade B or C PF. CONCLUSIONS We propose our anastomotic technique that could simultaneously prevent PF and keep the pancreatic duct patent.

Abstract
Background The diagnostic value of hemoglobin (Hb) for detecting a significant hemorrhage (SH) in the early phase of trauma remains controversial. The present study aimed to assess the abilities of Hb measurements taken at different times throughout trauma management to identify patients with SH. Methods All consecutive adult trauma patients directly admitted to six French level-1 trauma centers with at least one prehospital Hb measurement were analyzed. The abilities of the following variables to identify SH (≥ 4 units of red blood cells in the first 6 h and/or death related to uncontrolled bleeding within 24 h) were determined and compared to that of shock index (SI): Hb as measured with a point-of-care (POC) device by the prehospital team on scene (POC-Hbprehosp) and upon patient’s admission to the hospital (POC-Hbhosp), the difference between POC-Hbhosp and POC-Hbprehosp (DeltaPOC-Hb) and Hb as measured by the hospital laboratory on admission (Hb-Labhosp). Results A total of 6402 patients were included, 755 with SH and 5647 controls (CL). POC-Hbprehosp significantly predicted SH with an area under ROC curve (AUC) of 0.72 and best cutoff values of 12 g/dl for women and 13 g/dl for men. POC-Hbprehosp < 12 g/dl had 90% specificity to predict of SH. POC-Hbhosp and Hb-Labhosp (AUCs of 0.92 and 0.89, respectively) predicted SH better than SI (AUC = 0.77, p < 0.001); best cutoff values of POC-Hbhosp were 10 g/dl for women and 12 g/dl for men. DeltaPOC-Hb also predicted SH with an AUC of 0.77, a best cutoff value of − 2 g/dl irrespective of the gender. For a same prehospital fluid volume infused, DeltaPOC-Hb was significantly larger in patients with significant hemorrhage than in controls. Conclusions Challenging the classical idea that early Hb measurement is not meaningful in predicting SH, POC-Hbprehosp was able, albeit modestly, to predict significant hemorrhage. POC-Hbhosp had a greater ability to predict SH when compared to shock index. For a given prehospital fluid volume infused, the magnitude of the Hb drop was significantly higher in patients with significant hemorrhage than in controls.

Abstract
Liver metabolism undergoes robust circadian oscillations in gene expression and enzymatic activity essential for liver homeostasis, but whether the circadian clock controls homeostatic self-renewal of hepatocytes is unknown. Here we show that hepatocyte polyploidization is markedly accelerated around the central vein, the site of permanent cell self-renewal, in mice deficient in circadian Period genes. In these mice, a massive accumulation of hyperpolyploid mononuclear and binuclear hepatocytes occurs due to impaired mitogen-activated protein kinase phosphatase 1 (Mkp1)-mediated circadian modulation of the extracellular signal-regulated kinase (Erk1/2) activity. Time-lapse imaging of hepatocytes suggests that the reduced activity of Erk1/2 in the midbody during cytokinesis results in abscission failure, leading to polyploidization. Manipulation of Mkp1 phosphatase activity is sufficient to change the ploidy level of hepatocytes. These data provide clear evidence that the Period genes not only orchestrate dynamic changes in metabolic activity, but also regulate homeostatic self-renewal of hepatocytes through Mkp1-Erk1/2 signaling pathway. Circadian clock regulates hepatic gene expression and functions. Here Chao et al. show that alteration of circadian clock genes by Period deletion induces polyploidy in hepatocytes due to impaired regulation of Erk signaling by mitogen-activated protein kinase phosphatase 1.

Abstract
Streptococcus mutans produces three glucosyltransferases, coded by gtfB, gtfC, and gtfD, whose cooperative action is essential for sucrose-dependent cellular adhesion. This cellular adhesion plays an important role in the formation of dental plaque and the initiation of dental caries. Since they bear genetic similarities and are large in size, differentiation of their gene expression has been difficult, and little is known about the dynamic process of gtf expression. Using a real-time reverse-transcription/polymerase chain-reaction, we determined the expression of each gtf. Under various conditions, the relative levels of transcription were gtfB > gtfD > gtfC. Sucrose enhanced gtfD expression, whereas it reduced that of gtfB and gtfC, suggesting the presence of independent promoters. Quantitative analyses demonstrated coincidence between the ratio of expression of each gtf and the ratio previously identified as optimal for sucrose-dependent adhesion in vitro, suggesting that S. mutans produces GTF at an optimal ratio to adhere to the tooth surface.

Abstract
Recent schizophrenia (SCZ) studies have reported an increased burden of de novo copy number variants (CNVs) and identified specific high-risk CNVs, although with variable phenotype expressivity. However, the pathogenesis of SCZ has not been fully elucidated. Using array comparative genomic hybridization, we performed a high-resolution genome-wide CNV analysis on a mainly (92%) Japanese population (1699 SCZ cases and 824 controls) and identified 7066 rare CNVs, 70.0% of which were small (<100 kb). Clinically significant CNVs were significantly more frequent in cases than in controls (odds ratio=3.04, P=9.3 × 10-9, 9.0% of cases). We confirmed a significant association of X-chromosome aneuploidies with SCZ and identified 11 de novo CNVs (e.g., MBD5 deletion) in cases. In patients with clinically significant CNVs, 41.7% had a history of congenital/developmental phenotypes, and the rate of treatment resistance was significantly higher (odds ratio=2.79, P=0.0036). We found more severe clinical manifestations in patients with two clinically significant CNVs. Gene set analysis replicated previous findings (e.g., synapse, calcium signaling) and identified novel biological pathways including oxidative stress response, genomic integrity, kinase and small GTPase signaling. Furthermore, involvement of multiple SCZ candidate genes and biological pathways in the pathogenesis of SCZ was suggested in established SCZ-associated CNV loci. Our study shows the high genetic heterogeneity of SCZ and its clinical features and raises the possibility that genomic instability is involved in its pathogenesis, which may be related to the increased burden of de novo CNVs and variable expressivity of CNVs.

Abstract
Glucosyltransferases (GTF)-I and GTF-SI of Streptococcus mutans synthesize water-insoluble and both water-soluble and -insoluble glucans, respectively, and play essential roles in the sucrose-dependent adhesion of the organism to tooth surfaces. To examine the interactions of different GTFs on artificial biofilm formed by S. mutans and other oral streptococci, we generated GTF-I- and GTF-SI-hyperproducing isogenic mutant strains. Transformant B42-21, which hyperexpressed GTF-SI, exhibited firm adhesion in the presence of sucrose, whereas transformant B42-10, which hyperexpressed GTF-I, failed to exhibit firm adhesion. Furthermore, co-culture of transformant B42-21 with water-soluble glucan-synthesizing Streptococcus sanguinis yielded firm adhesion, while the addition of dextran T10 to B42-21 growing culture had no effect on adhesion. These findings suggest that GTF-SI has a strong effect on sucrose-dependent adhesion and is essential for biofilm formation on smooth surfaces, in cooperation with water-soluble glucans synthesized de novo by oral streptococci that inherently lack cell adhesion ability.

Abstract
Water-insoluble α-glucans are synthesized from sucrose by glucosyltransferase-I of mutans streptococci and play an important role in the development of dental plaque. Several types of β-glucans in fungal cell wall components and water-soluble α-glucans from Streptococcus mutans are known to modulate innate immunity. In the present study, we investigated whether water-insoluble α-glucans also induced inflammatory innate immune responses. Our results showed that water-insoluble α-glucans synthesized by Streptococcus sobrinus activated mouse peritoneal exudate macrophages to produce pro-inflammatory cytokines. The immunological responses were not due to contamination by sucrose, water-soluble α-glucan, lipopolysaccharide, or peptidoglycan. Furthermore, human monocytes stimulated by water-insoluble α-glucans produced TNF-α and IL-8, while human polymorphonuclear cells were activated by water-insoluble α-glucans, resulting in chemotaxis and hydrogen peroxide production. The results demonstrated that water-soluble α-glucans modulate macrophage- and granulocyte-induced inflammatory immune responses, and suggest that inflammation induced by those α-glucans is associated with the development of periodontal diseases.

Abstract
Computed tomographic appearances of 147 surgically proven mediastinal tumors (113 benign and 34 malignant lesions) were evaluated paying special attention to their localization or extension. Ten of the 113 benign lesions (9%) showed atypical or unique localization or extension, and were divided into three groups. In the first group, two lymphangiomas and one bronchogenic cyst spread over both the precardiovascular and the retrocardiovascular compartments, mimicking a malignant lesion. In the second group, the single cases of thymic hypertrophy, thymic cyst, schwannoma, and pericardial cyst were located atypically in the retrocardiovascular compartment. In the last group, two esophageal leiomyomas and one esophageal duplication showed upward and downward longitudinal extension beyond the azygos arch and the aortic arch.

Abstract
We aimed to histologically observe portal venous gas (PVG)-causing intestinal pneumatosis (IP) and evaluate pathogenic mechanisms and therapeutic strategies, including decisions on whether emergency surgery should be performed. Autopsy was performed in two cases of nonocclusive mesenteric ischemia (NOMI). We directly histologically observed the pathogenic mechanisms of IP caused by gas-producing bacteria and IP considered to be caused by mechanical damage to the intestinal mucosa. IP can be classified hypothetically into the following types according to pathogenesis: (1) infection, (2) rupture (damage) of the intestinal mucosa + increased intestinal intraluminal pressure, and (3) mixed type. In cases of IP caused by gas-producing bacteria or IP associated with intestinal wall damage extending beyond the mucosa to the deep muscular layer, emergency surgery should be considered. However, it is highly possible that patients who test negative for infection with gas-producing bacteria whose intestinal wall damage remains only in the mucosa can be conservatively treated.

Abstract
The aims of this study were: (i) to elucidate clinicopathological characteristics of pcCHS of long bones (L), limb girdles (LG) and trunk (T) in Japan; (ii) to investigate predictive pathological findings for outcome of pcCHS of L, LG and T, objectively; and (iii) to elucidate a discrepancy of grade between biopsy and resected specimens. Clinicopathological profiles of 174 pcCHS (79 male, 95 female), of L, LG, and T were retrieved. For each case, a numerical score was given to 18 pathological findings. The average age was 50.5 years (15-80 years). Frequently involved sites were femur, humerus, pelvis and rib. The 5-year and 10-year disease-specific survival (DSS) rates [follow-up: 1-258 months (average 65.5)] were 87.0% and 80.4%, respectively. By Cox hazards analysis on pathological findings, age, sex and location, histologically higher grade and older age were unfavorable predictors, and calcification was a favorable predictor in DSS. The histological grade of resected specimen was higher than that of biopsy in 37.7% (26/69 cases). In conclusion, higher histological grade and older age were predictors for poor, but calcification was for good prognosis. Because there was a discrepancy in grade between biopsy and resected specimens, comprehensive evaluation is necessary before definitive operation for pcCHS.

Abstract
OBJECTIVES To determine whether uterine artery (UtA) Doppler findings and three-dimensional (3D) ultrasound measurement of placental volume during the first trimester allowed prediction of early- and late-onset pregnancy-induced hypertension (early PIH and late PIH). METHODS Subjects with singleton pregnancy who underwent an ultrasound scan at 11-13 weeks' gestation and delivered between 2011 and 2013 were enrolled prospectively into the study. The UtA Doppler indices and placental volume on 3D ultrasound at 11-13 weeks' gestation in cases that developed early PIH (< 34 weeks) or PIH later in pregnancy (≥ 34 weeks) were compared with values in unaffected pregnancies. RESULTS Ten cases of early PIH, 67 cases of late PIH and 1285 unaffected pregnancies were analyzed. The UtA pulsatility index (PI) was higher in cases of early PIH than that in unaffected pregnancies (median, 2.35 vs. 1.79; P = 0.043) but did not differ between cases of late PIH and unaffected pregnancies. Placental volume was smaller in cases of early PIH than that in unaffected pregnancies (median, 43 cm3 vs. 62 cm(3) ; P = 0.003) but did not differ between cases of late PIH and unaffected pregnancies. The area under the receiver-operating characteristics curve for the prediction of early PIH, by combining UtA-PI and placental volume, was 0.832 (95% CI, 0.742-0.921), with this combination providing a detection rate for early PIH of 67.5% for a 5% false-positive rate. CONCLUSIONS High UtA-PI and small placental volume were observed more often in cases of early PIH compared with unaffected pregnancies, but not in cases of late PIH. These results may indicate that there are differences in pathophysiology between early PIH and late PIH.

Abstract
PURPOSE Corneal collagen crosslinking (CXL) is a relatively new technique to reduce the progression of keratoconus. The technique can be performed with or without complete debridement of the corneal epithelium. We describe a novel intermediate technique involving mechanical disruption of the epithelium, and evaluate its safety and efficacy. METHODS The case notes of 128 eyes with progressive keratoconus or iatrogenic corneal ectasia who had undergone CXL using the epithelial disruption technique were retrospectively reviewed. Thin corneas were treated with hypotonic riboflavin. All others were treated with an isotonic solution. Note was made of preoperative and postoperative parameters, including uncorrected visual acuity (UCVA), best spectacle-corrected visual acuity (BSCVA), refraction, endothelial cell count, and corneal tomography. Occurrence of procedure-related complications was recorded. Statistical analyses were performed using the paired sample t-test and Wilcoxon signed-rank test, with a level of P<0.05 being accepted as statistically significant. RESULTS At 12 months, 41.8% of patients treated with isotonic riboflavin had improved UCVA and 29.7% had improved BSCVA. Only 13.4% lost lines of UCVA and 14.9% lost BSCVA. Of the patients treated with hypotonic riboflavin, at 12 months, 75% demonstrated stability of BSCVA and 25% had stable Kmax. In addition, 25% showed improved visual acuity at 12 months, and 58.3% showed regression of their Kmax. Our rate of short-term complications was comparable to studies using complete epithelial removal. CONCLUSIONS CXL with epithelial disruption is a safe and effective treatment for keratoconus or iatrogenic corneal ectasia, and may be better tolerated by patients than the epithelium-off technique.

Abstract
BACKGROUND Rapid diagnosis of coagulopathy in the bleeding patient using point-of-care (POC) devices would be ideal. The Hemochron Signature Elite(®) (HC(®)) is a POC device that determines international normalized ratio (INR) and activated partial thromboplastin time (aPTT). The aim of the study was to evaluate the agreement for INR and aPTT between the HC(®) and standard laboratory values in acute haemorrhage. METHODS This was a single-centre observational prospective study including patients with acute haemorrhage. Laboratory INR and aPTT were compared with simultaneous measurements performed with the HC(®). The diagnostic performance of HC(®) was determined; bias and limits of agreement were calculated according to the method of Bland and Altman. RESULTS Seventy-two pairs of measurements from 39 patients were analysed. The bias between the INR-HC(®) and aPTT-HC(®) measurements and the central laboratory were 0.02 and -1.13, respectively. The Spearman's correlation coefficients for the INR-HC(®)/INR-lab and the aPTT-HC(®)/aPTT-lab were 0.68 and -0.29, respectively. Twenty-seven per cent of INR-HC(®) values and 89% of the aPTT-HC(®) values exceeded the predefined limits of agreement. The INR-HC(®) measurement identified patients with a central laboratory INR >1.5 with a sensitivity, specificity, and positive and negative predictive values of 83%, 70%, 76%, and 77%, respectively. CONCLUSIONS The results showed a lack of agreement between the INR-HC(®) and the aPTT-HC(®) measurements and the standard laboratory in the context of acute haemorrhage. The INR-HC(®) showed moderate performance as a decision-making tool to detect coagulopathy in the context of acute haemorrhage.

Abstract
The initial management of trauma patient is a critical period aiming at: stabilizing the vital functions; following a rigorous injury assessment; defining a therapeutic strategy. This management has to be organized to minimize loss of time that would be deleterious for the patients outcome. Thus, before patient arrival, the trauma team alert should lead to the initiation of care procedures adapted to the announced severity of the patient. Moreover, each individual should know its role in advance and the team should be managed by only one individual (the trauma leader) to avoid conflicts of decision. A rapid trauma injury assessment aims not only at guiding resuscitation (chest drainage, pelvic contention, to define the mean arterial pressure goal) but also to decide a critical intervention in case of hemodynamic instability (laparotomy, thoracotomy, arterial embolisation). This initial assessment includes a chest and a pelvic X-ray, abdominal ultrasound (extended to the lung) and transcranial Doppler (TCD). The whole body scanner with administration of intravenous contrast material is the cornerstone of the injury assessment but can be done for patients stabilized after the initial resuscitation.

A 66-year-old man with a history of multiple transurethral resections for recurrent bladder tumors, staged as Ta according to the International Union Against Cancer staging guidelines, presented with a complaint of dry cough. A round nodule with a diameter of 7.5 cm was detected in the lung by chest computed tomography, and a video-assisted thoracoscopic lobectomy was performed. Pulmonary metastasis of recurrent bladder cancer was diagnosed by immunohistochemistry staining for the urothelium-specific protein uroplakin Ia. Subsequently, 2 cycles of systemic chemotherapy were administered. Two and a half years after treatment, no recurrence of pulmonary lesions has been detected. A combination of complete resection of pulmonary lesions and systemic chemotherapy may result in a good prognosis for patients with non-muscle-invasive bladder cancer.

Abstract
BACKGROUND Pemphigus vulgaris is a bullous auto-immune disease affecting the skin and mucosa. It is characterised by acantholysis that results in the formation of intraepithelial bullous lesions. Herein we report a case distinguished by its unusual clinical presentation. PATIENTS AND METHODS A 45-year-old man, a chronic smoker, consulted for hyperkeratotic lesions of the toes on the right foot present for 5 months. Examination revealed a violet colour of the toes associated with localised yellowish keratoderma on the sole of the foot and impaired toe nails, as well as impairment on the nails of the first, third and fourth fingers on the right hand. In addition, two hyperkeratotic plaques with crusts were noted on the patient's forehead. Histological examination of a biopsy sample taken from the nail bed of the fourth toe on the right foot showed suprabasal acantholysis with a characteristic tombstone appearance. Direct immunofluorescence confirmed the diagnosis of pemphigus. Oral corticosteroid therapy was initiated consisting of prednisone 1.5mg/kg per day. Improvement of the nail lesions and subsidence of the lesions on the patient's forehead occurred after three months of treatment. DISCUSSION During the course of pemphigus, the nail findings most commonly reported in the literature are paronychia, onychomadesis and onycholysis. However, these signs are generally seen in patients with known pemphigus vulgaris and only rarely indicate bullous disease. The case we report illustrates a special situation in which pemphigus vulgaris was revealed by unusual skin and nail lesions.
