Abstract
Abstract
Background/Introduction
The National Nutrition Survey in Japan indicated that dietary salt intake of the Japanese is gradually decreasing for the last several decades, while salt intakes are higher in elderly than young people. There is no survey on the alteration of salt intakes with advancing age in individuals.
Purpose
The present study investigated effects of aging on salt intakes in individuals.
Methods
A total of 2600 subjects (men; 1787, age; 30 to 79 years-old at 2008) who participated in our physical check-up program both in 2008 and 2018 were enrolled. Individual dietary salt intakes in 2008 and 2018, which were estimated using a spot urine by a previously reported method, were compared.
Results
The mean age and salt intakes at 2008 were 53.9±10.0 years and 12.2±3.2 g/day in men and 54.4±9.2 years and 8.3±2.1 g/day in women, respectively. Salt intake increased to 13.2±3.3 g/day in men and 8.8±2.2 g/day in women during the 10 years. Salt intakes were higher in hypertensive than normotensive subjects both at 2008 and 2018, but changes of blood pressure category were not associated with those of salt intakes during the 10 years (table). Changes in salt intakes in each decade are shown in Figure. Salt intakes in each decade increased with advancing age both in men and women until their 70s. Salt intakes in people in their 60s and 70s at 2018 were higher than those at 2008. Similar results were obtained in subjects without any anti-hypertensive medications (n=1667) (data not shown).
Conclusions
The observational follow-up study revealed that salt intakes in each individual increased after the interval of 10 years in both men and women. The results suggest that the sense of taste changes with advancing age in young adults as well as elderly persons, which may be related with alterations of lifestyle.

Abstract
Abstract
Background/Introduction
Hypertension induces kidney dysfunction, and vice versa. Furthermore, kidney dysfunction can be a risk factor for cardiovascular diseases as well as end-stage of kidney disease. Although blood pressure (BP) control is necessary to prevent deterioration of kidney function, strict BP control may deteriorate kidney function.
Purpose
The present observational study investigated effects of BP levels on the incidence of chronic kidney disease (CKD) in the general population.
Methods
A total of 12,753 subjects with normal kidney function (estimated glomerular filtration rate [eGFR] ≥60 mL/min per 1.73 m2) (male 7,707, mean age 51.8 years) who visited our hospital for an annual physical check-up from April 2010 to March 2018 were enrolled. After baseline examination, subjects were followed up until March 2019 (median 1769 days) with the endpoint being the development of CKD (eGFR<60 mL/min per 1.73 m2). The modified MDRD formula for Japanese was used to calculate eGFR. Hypertension was defined as BP ≥140/90mmHg or the use of antihypertensive medication.
Results
During the follow-up period, 1,604 subjects developed CKD (26.9 per 1,000 person-years) with the incidence being more frequent in hypertensive (n=3,098) than normotensive (n=9,655) subjects at enrollment (44.2 vs. 21.5 per 1,000 person-years, respectively; hazard ratio [95% confidence interval] from multivariate Cox proportional analysis 1.205 [1.061–1.369]). Hazard ratio of systolic BP at baseline was 1.006 [1.002–1.010] in a multivariate Cox proportional hazard regression model adjusted for possible risk factors. The incidence was lower in subjects without hypertension throughout the follow-up period (normotension group, n=7,866) than those who were diagnosed as having hypertension at least once during the period (hypertension group, n=4,887) (23.1 vs. 32.3 per 1,000 person-years, p<0.001). In the normotension group, subjects with average BP <120/80mmHg had lower incidence of CKD than in those with BP ≥120/80mmHg (17.2 vs. 36.1 per 1,000 person-years, p<0.001). In contrast, in the hypertension group, the incidences of CKD in subjects with average BP <120/80, 120–139/80–89 and ≥140/90mmHg were 34.3, 25.8, and 54.4 per 1,000 person-years, respectively (p<0.001). Moreover, in hypertensive subjects under medication (n=2,002) with average BP <120/80, 120–139/80–89 and ≥140/90mmHg, the incidence of CKD was 65.5, 41.3, and 64.3 per 1,000 person-years, respectively (p<0.01).
Conclusions
The incidence of CKD was higher in hypertensive than in normotensive subjects. The lower BP was associated with the lower incidence of CKD in normotensive subjects, while strict BP control may increase the risk of CKD in hypertensive subjects.

Abstract
Abstract
Background/Introduction
Dietary salt consumption is one of the most important modifiable factors in our lifestyle and restriction of dietary salt results in the reduction of blood pressure in previous studies. Excessive salt intake causes cardiovascular diseases independently of its effects on blood pressure. Since metabolic syndrome also increases a risk of cardiovascular disease, there may be some association between salt intake and metabolic syndrome.
Purpose
The present study was designed to investigate a possible relationship between salt intake and future development of metabolic syndrome in the general population.
Methods
Consecutive 12,256 subjects without metabolic syndrome (male=7,053, 52.1±12.3 year-old) who visited our hospital for an annual physical check-up from April 2010 to March 2018 were enrolled. After baseline examination, subjects were followed up until March 2019 (median 1,582 days) with the endpoint being the development of metabolic syndrome. Metabolic syndrome was diagnosed according to the Japanese criteria (2005). Individual salt intake was estimated using a spot urine by a previously reported method.
Results
Salt intake was 11.9±3.0 g/day in male and 8.2±2.1 g/day in female subjects at baseline. During the follow-up period, 1,669 subjects developed metabolic syndrome (29.9 per 1,000 person-year) with the incidence being more frequent in male than female subjects (41.8 vs. 14.2 per 1,000 person-year). Non-adjusted hazard ratio (HR) (95% confidence interval [CI]) of salt intake for the development of metabolic syndrome was 1.157 (1.142–1.173). In analysis where subjects were divided into gender-specific quartiles according to the baseline salt intake, Kaplan-Meyer curve analysis revealed that the incidence of metabolic syndrome were increased across the quartiles (20.6, 25.0, 32.4, and 42.7 per 1,000 person-years; logrank p<0.001). Multivariate Cox proportional hazard analysis adjusted for age, gender, body mass index, systolic blood pressure, heart rate, serum creatinine, uric acid, fasting plasma glucose, low-density lipoprotein cholesterol, triglyceride, hemoglobin and current smoking habit at baseline revealed that salt intake predicted the new onset of metabolic syndrome (HR: 1.036, 95% CI: 1.019–1.054).
Conclusions
Excessive salt intake is significantly associated with the new development of metabolic syndrome in the general population. The results suggest that salt restriction prevents metabolic syndrome as well as hypertension leading to cardiovascular diseases.

Abstract
Abstract
Background/Introduction
An impairment of kidney function is a risk not only for end stage renal disease but also for cardiovascular events. Hypertension is known to accelerate an age-dependent decline in glomerular filtration rate (GFR).
Purpose
Effects of antihypertensive medications on yearly changes of estimate GFR (eGFR) in hypertensive patients were investigated.
Methods
Consecutive 5110 subjects (male=3196, 52.3±11.3 year-old) who participated in our physical check-up program during 2010 and 2012 were enrolled and followed up for 5 years. The average and the yearly change of eGFR during the 5 years were calculated in each individual and the both values were compared in hypertensive and normotensive subjects. Effect of antihypertensive medication on eGFR was also investigated. The modified Modification of Diet in Renal Disease study formula for the Japanese population was used for calculating eGFR.
Results
In hypertensive subjects (n=1408), the baseline and the average of eGFR were smaller (74.8±14.6 vs. 80.4±13.6, p<0.001 and 72.1±13.2 vs. 77.9±11.9 mL/min per 1.73 m2, p<0.001, respectively) and the yearly decline of eGFR was greater (0.96±1.41 vs. 0.84±1.19 mL/min per 1.73 m2 per year, p<0.01) than in normotensive subjects (n=3702). The baseline and the average of eGFR were smaller in hypertensive patients with (n=1234) than without (n=174) antihypertensive medication (74.3±14.6 vs. 78.3±13.8, p<0.001 and 71.7±13.2 vs. 74.9±12.7 mL/min per 1.73 m2, p<0.01, respectively). Although the yearly decline of eGFR in hypertensive patients with medication tended to be smaller than the decline in those without medication (0.94±1.41 vs. 1.09±1.42 mL/min per 1.73 m2 per year), this did not reach a statistical significance (p=0.213). Neither the number, classes of antihypertensive medications nor systolic blood pressure during the follow-up period did affect the average or yearly decline of eGFR in hypertensive patients.
Conclusions
As compared to normotensive subjects, eGFR was reduced and a yearly decrease in eGFR during the 5 years was accelerated in hypertensive patients. Although antihypertensive medication may reduce an accelerated age-dependent decline of kidney function in hypertension, observational period in this study was too short to clarify such beneficial effects of antihypertensive medications.

Abstract
Abstract
Background/Introduction
Health check-up has been carried out for individual health management. One of its main objectives is the early detection and prevention of major adverse cardiovascular event (MACE).
Purpose
We investigated predictive factors for MACE among clinical test items in health check-up program.
Methods
A total of 13522 subjects (male=8140, 52.8±12.3 year-old at baseline), who visited our hospital for a health check-up between 2008 and 2015, were enrolled. After the baseline examination, they were followed up until December 2016 (median 1827 days) with the endpoint being the incident of MACE. The outcome was confirmed using a questionnaire at health check-up, medical record, telephone, or letter. Possible association between MACE and clinical test items including gender, age, waist circumference, blood pressure, kidney function, fasting plasma glucose, lipid profile, hemoglobin, electrocardiogram (ECG), smoking habit and alcohol consumption was investigated.
Results
During the follow-up period, MACE occurred in 196 subjects (3.03 per 1000 person-year), with the incidence being more frequent in male than female subjects (4.07 vs. 1.42 per 1000 person-year). Multivariate Cox-hazard analysis demonstrated that male gender (hazard ratio [HR] = 2.457, 95% confidence intervals [CI] = 1.498–4.028), age (HR = 1.056, 95% CI = 1.040–1.071), waist circumference (HR = 1.023, 95% CI = 1.004–1.042), systolic blood pressure (HR = 1.015, 95% CI = 1.005–1.024), hemoglobin (HR = 0.868, 95% CI = 0.758–0.994) and Sokolow–Lyon voltage in the ECG (HR = 1.227, 95% CI = 1.033–1.458) were significant predictors for MACE. However, in a model where B-type natriuretic peptide (BNP) was also added as an independent variable, BNP (HR = 2.593, 95% CI = 1.602–4.196) was the strongest predictor for MACE.
Conclusions
In participants underwent health check-up, systolic blood pressure and hemoglobin as well as age and gender were the risk factors of MACE. Appropriate control of blood pressure and treatment of anemia may be useful for the prevention of MACE. Measurement of BNP may give us additional important information associated with future MACE.

Abstract
BACKGROUND Over the past decade, numerous reports describe the generation and increasing utility of non-small-cell lung cancer (NSCLC) patient-derived xenografts (PDX) from tissue biopsies. While PDX have proven useful for genetic profiling and preclinical drug testing, the requirement of a tissue biopsy limits the available patient population, particularly those with advanced oligometastatic disease. Conversely, 'liquid biopsies' such as circulating tumour cells (CTCs) are minimally invasive and easier to obtain. Here, we present a clinical case study of a NSCLC patient with advanced metastatic disease, a never smoker whose primary tumour was EGFR and ALK wild-type. We demonstrate for the first time, tumorigenicity of their CTCs to generate a patient CTC-derived eXplant (CDX). PATIENTS AND METHODS CTCs were enriched at diagnosis and again 2 months later during disease progression from 10 ml blood from a 48-year-old NSCLC patient and implanted into immunocompromised mice. Resultant tumours were morphologically, immunohistochemically, and genetically compared with the donor patient's diagnostic specimen. Mice were treated with cisplatin and pemetrexed to assess preclinical efficacy of the chemotherapy regimen given to the donor patient. RESULTS The NSCLC CDX expressed lung lineage markers TTF1 and CK7 and was unresponsive to cisplatin and pemetrexed. Examination of blood samples matched to that used for CDX generation revealed absence of CTCs using the CellSearch EpCAM-dependent platform, whereas size-based CTC enrichment revealed abundant heterogeneous CTCs of which ∼80% were mesenchymal marker vimentin positive. Molecular analysis of the CDX, mesenchymal and epithelial CTCs revealed a common somatic mutation confirming tumour origin and showed CDX RNA and protein profiles consistent with the predominantly mesenchymal phenotype. CONCLUSIONS This study shows that the absence of NSCLC CTCs detected by CellSearch (EpCAM(+)) does not preclude CDX generation, highlighting epithelial to mesenchymal transition and the functional importance of mesenchymal CTCs in dissemination of this disease.

Abstract
Epithelioid haemangioma of the penis is a rare condition which usually presents a solid single nodule. We report a case in a 43-year-old man who presented with painful erections and sleep disturbance with two palpable penile nodules. Magnetic resonance imaging with an artificially induced erection revealed these as individual lesions, and local excision was successfully undertaken. Pathological diagnosis of epithelioid haemangioma was confirmed with positive staining for CD31. Although rare, penile epithelioid haemangioma should be considered as a differential in an atypical penile mass. Induction in of an artificial erection prior to MRI can aid diagnosis and treatment is typically with surgical excision.

Abstract
INTRODUCTION Award schemes and self-evaluation systems have been developed to implement the 'Health-Promoting School (HPS)' concept in European and Asian countries. While there have been many successes in these regions, the implementation of HPS in African countries has been minimal. This study evaluated the impact of a self-evaluation system on school health in Niger. METHODS A school health activity guide was developed and distributed to 1999 primary schools in the Niger Tahoua region to raise awareness and solve problems related to school health and hygiene. The number of schools that planned or implemented health-related activities, and the budget and implementation status of their activities was compared over 3 years (before, soon after, and 1 year after distribution). Focus group discussions (FGDs) were also conducted targeting Conseillers Pédagogiques (CPs), who supervise primary schools and teachers, primary school principals and members of Comité de Gestion des Etablissement Scolaire (COGES), which is a type of school steering committee. RESULTS The number of schools planning at least one health-related activity increased from 47% to 79% soon after distribution of the guide (p <0.001).The number of schools implementing activities increased from 44% to 65% one year after distribution (p <0.001). Health-related budget per school also increased after distribution (p <0.0001) and increases were maintained 1 year after the intervention (p=0.8414). Fulfilment or partial fulfilment rates for health-related activities were lower compared with other (non-health) activities in all three years (80%, 77% & 84% in health-related activities vs 88%, 90% & 91% in others; p <0.001, p <0.001, & p=0.004, respectively). Most FGD participants expressed a positive impression of the program and noted the usefulness of the guide. However, some respondents reported difficulties, especially in relation to budget. CONCLUSION The introduction of a health activity guide for self-assessment was effective in increasing health-related activities in primary schools in Niger, where a simple monitoring system should be introduced to establish the HPS concept.

Abstract
BACKGROUND Salivary adenoid cystic carcinoma (ACC) is an insidious slow-growing cancer with the propensity to recur and metastasise to distant sites. Basal-like breast carcinoma (BBC) is a molecular subtype that constitutes 15-20% of breast cancers, shares histological similarities and basal cell markers with ACC, lacks expression of ER (oestrogen receptor), PR (progesterone receptor), and HER2 (human epidermal growth factor receptor 2), and, similar to ACC, metastasises predominantly to the lung and brain. Both cancers lack targeted therapies owing to poor understanding of their molecular drivers. METHODS Gene expression profiling, immunohistochemical staining, western blot, RT-PCR, and in silico analysis of massive cancer data sets were used to identify novel markers and potential therapeutic targets for ACC and BBC. For the detection and comparison of gene signatures, we performed co-expression analysis using a recently developed web-based multi-experiment matrix tool for visualisation and rank aggregation. RESULTS In ACC and BBC we identified characteristic and overlapping SOX10 gene signatures that contained a large set of novel potential molecular markers. SOX10 was validated as a sensitive diagnostic marker for both cancers and its expression was linked to normal and malignant myoepithelial/basal cells. In ACC, BBC, and melanoma (MEL), SOX10 expression strongly co-segregated with the expression of ROPN1B, GPM6B, COL9A3, and MIA. In ACC and breast cancers, SOX10 expression negatively correlated with FOXA1, a cell identity marker and major regulator of the luminal breast subtype. Diagnostic significance of several conserved elements of the SOX10 signature (MIA, TRIM2, ROPN1, and ROPN1B) was validated on BBC cell lines. CONCLUSION SOX10 expression in ACC and BBC appears to be a part of a highly coordinated transcriptional programme characteristic for cancers with basal/myoepithelial features. Comparison between ACC/BBC and other cancers, such as neuroblastomaand MEL, reveals potential molecular markers specific for these cancers that are likely linked to their cell identity. SOX10 as a novel diagnostic marker for ACC and BBC provides important molecular insight into their molecular aetiology and cell origin. Given that SOX10 was recently described as a principal driver of MEL, identification of conserved elements of the SOX10 signatures may help in better understanding of SOX10-related signalling and development of novel diagnostic and therapeutic tools.

Abstract
11069 Background: Recent advances in biologically directed therapies for non-small cell lung carcinoma (NSCLC) emphasize the need for more accurate sub-classification of NSCLC, as treatment may be dictated by histologic subtype. In particular, squamous histology can be a counter-indication for treatment by VEGF inhibitors. MicroRNAs are highly tissue-specific biomarkers with potential clinical applicability for defining cancer type and origin. MicroRNAs are well preserved in formalin fixed tissue, making them ideal candidates for molecular markers for use in routinely processed material. Here we report on the development and performance of a microRNA-based assay for the differential diagnosis of squamous from non-squamous NSCLC. Methods: We developed protocols for extraction of high-quality RNA that retain the microRNA fraction from FFPE archival tissue samples. MicroRNA microarrays were used to profile more than a hundred NSCLC samples. Specific microRNA qRT-PCR was used to validate results, and to develop a diagnostic assay. Results: We identified a microRNA biomarker that is strongly overexpressed in squamous cell NSCLC. A diagnostic assay (miRview squamous) was developed, that utilizes qRT-PCR measurement of this microRNA, normalized by an additional microRNA and a small nuclear RNA. This assay was validated on a blinded test set of 64 tumor samples, and had sensitivity of 97% and specificity of 91%. More than ¾ of the samples were classified with high confidence, and these classifications were accurate in 96% of the cases. Conclusions: MicroRNAs are becoming an important tool for classification of cancers. A diagnostic assay based on the specificity of a single microRNA accurately identifies squamous from non-squamous NSCLC. This assay provides an important new tool for the classification of NSCLC.

Abstract
11036 Background: Hundreds of thousands of patients are diagnosed each year with metastatic cancer. For ∼10% of these, the tumor primary site is never identified, and they are defined as Cancer of Unknown Primary (CUP). Identification of tumor tissue-of- origin has significant therapeutic implications and presents a major diagnostic challenge. In previous work we showed that by combining expression profiles of tissue-specific microRNAs with a biologically-motivated classification scheme, tumor tissue-of-origin can be identified with high accuracy. Here we describe the development of this approach into a practical diagnostic assay. Methods: We developed protocols for extraction of high-quality RNA that retain the microRNA fraction from FFPE archival tissue samples. Proprietary, highly specific qRT-PCR was used to profile microRNA expression levels in hundreds of samples. Results: A training set of nearly 400 primary and metastatic tumors samples with known primary sites, representing 25 different tumor types, was used to define a standardized diagnostics assay (miRview mets). The assay uses a qRT-PCR protocol to measure a panel of 48 microRNA biomarkers. The assay was validated on a test set of nearly 200 primary and metastatic tumors whose primary sites were blinded. The classification protocol identifies either a single, high-confidence origin or two possible low-confidence predictions. Overall, correct primary site was identified for 83% of the tumors. For 70% of the cases a single high-confidence prediction was made; these cases had a higher accuracy: 90% of the primary sites predicted with high confidence were accurately identified. Conclusions: Previous studies highlighted the tissue-specificity of microRNA expression. We developed this potential into a diagnostic assay that identifies tumor origins with high accuracy. This assay provides an important new tool for diagnosing tumor tissue origin. [Table: see text]

Abstract
BACKGROUND Multicystic peritoneal mesothelioma (MPM) and well-differentiated papillary peritoneal mesothelioma (WDPPM) are exceedingly uncommon lesions with uncertain malignant potential and no uniform treatment strategy. The aim of the current study was to review our experience with cytoreduction and hyperthermic intraperitoneal chemotherapy (HIPEC) in these clinical settings. METHODS Four women with MPM and eight with WDPPM underwent 13 procedures of cytoreduction and close-abdomen HIPEC with cis-platin and doxorubicin. Seven patients had recurrent disease after previous debulking (one operation in five patients, two in one, four in one). Potential clinicopathological prognostic factors were assessed. RESULTS Optimal cytoreduction (residual tumor nodules <or=2.5 mm) was performed in 12 of 13 procedures. Median follow-up was 27 months (range 6-94). One grade 4 postoperative complication (NCI/CTCAE v.3.0) and no operative mortalities occurred. One patient underwent the procedure twice due to locoregional MPM recurrence. Transition of typical WDPPM to malignant biphasic mesothelioma was documented in one patient who died of disease progression following incomplete cytoreduction and HIPEC. Following multimodality treatment, 5-year overall and progression-free survival were 90.0% (standard error = 9.0) and 79.7% (11.9), respectively. Progression-free survival following previous debulking surgery (median 24 months; range 2-87) was statistically worse (P = .0156). Incomplete cytoreduction and poor performance status correlated to both reduced overall and progression-free survival after cytoreduction and HIPEC. CONCLUSIONS MPM and WDPPM are borderline tumors capable of transformation into potentially lethal processes. Definitive tumor eradication by means of cytoreduction and HIPEC seems more effective than debulking surgery in preventing disease recurrence or transition to aggressive malignancies.

Abstract
8545 Purpose: This clinical trial evaluates the safety and adjuvant activity of imiquimod, a toll-like receptor (TLR)-7 agonist, when given with a NY-ESO-1 protein vaccine. Imiquimod, by locally activating and recruiting dendritic cells (DCs) into the skin, is expected to stimulate antigen uptake by DCs, induce maturation and migration to draining lymph nodes, and to induce antigen-specific T and B cell immunity. Methods: Pilot study; 9 patients with resected stage 2B-3C malignant melanoma. Four 21 day cycles consisted of topical imiquimod cream (250 mg) on days 1–5 and id. injected NY-ESO-1 protein (100 mcg) into the site on day 3. Blood was drawn at several time points for immune monitoring; skin punch biopsies were obtained from control, imiquimod and vaccination sites 48 hours after the last vaccination. Results: The regimen was tolerated well, all patients completed four vaccinations. AEs were mild and transient and included injection site reactions (8/9 patients), fatigue (4/9 patients) and fever (2/9 patients). Significant levels of antigen-specific CD4+ or CD8+ T cell responses were not detected in ex-vivo ELISPOT assays. However, intracellular cytokine staining assays after in vitro pre-stimulation indicated that 6 of 8 subjects developed NY-ESO-1 CD4+ T cell responses. Humoral immunity was manifest by the induction of anti-NY-ESO-1 antibodies in 7/9 patients post-vaccination. Histochemistry of skin sections showed significant dermal mononuclear cell infiltrates in Imiquimod treated skin, whereas none were seen in untreated skin (p<0.01). IHC revealed markedly increased numbers of CD3+ (T-cells), CD68+ (macrophages/monocytes), CD123+ (plasmacytoid DCs) and DC-LAMP+ (mature myeloid DCs) immune cells in Imiquimod treated skin when compared with control skin of the same patients (p<0.05). Conclusion: Imiquimod, a topical immune response modifier, generated clear inflammatory infiltrates in the dermis, with significant increases in antigen-presenting cells and T cells. Imiquimod was well tolerated when used as an adjuvant to an NY-ESO-1 protein vaccine. Systemic immunity of both humoral and cellular types was induced in the majority of patients; however, responses were weak and the vaccine combination needs to be optimized in future studies. No significant financial relationships to disclose.

Abstract
AIMS CDX-2 is a highly sensitive and specific marker of intestinal epithelial cells and their neoplastic counterparts. CDX-2 status in pseudomyxoma peritonei (PMP) has been barely reported. The aim of this study was to investigate the clinicopathological features of 42 cases of PMP with a special emphasis on CDX-2. METHODS AND RESULTS All patients were treated by cytoreduction. Immunohistochemistry was performed for CDX-2, MUC-2, MUC-5AC, cytokeratin (CK) 7 and CK20. Statistical correlation was evaluated for age, sex, completeness of cytoreduction and histological subtype with overall and progression-free survival (OS and PFS). PMP consisted of 32 cases of disseminated peritoneal adenomucinosis and 10 cases of peritoneal mucinous carcinomatosis. The appendix evaluated in 25 cases showed two mucinous adenocarcinomas and 21 low-grade appendiceal mucinous neoplasms. CDX-2 was diffusely positive in 40 cases, with the remaining two cases being focally positive. All cases demonstrated diffuse reactions to CK20 and MUC-2, and variable reactions to MUC-5AC, while CK7 was variably positive in 38 cases. Five-year OS was 97%. Histological type was significantly correlated with PFS (P=0.02). CONCLUSIONS CDX-2 is diffusely and strongly positive in PMP. This is a useful marker to confirm an appendiceal origin of PMP, particularly when used in conjunction with CK7, CK20, MUC-2 and MUC-5AC.

Abstract
Uterine leiomyosarcoma (ULMS) is an aggressive gynecological disease. Although ULMS are often found in association with benign leiomyoma (LMA), little is known regarding the relationship between these benign and malignant smooth muscle neoplasms. The objective of this study was to evaluate the expression of epidermal growth factor (EGFR), platelet-derived growth factor (PDGFR), and p53 in ULMS specimens, their prognostic relevance, and the expression of these molecular markers when compared to benign LMA specimens. Between 1991 and 2001, 25 patients were identified with high-grade primary ULMS and for whom tissue was available. Tissue microarray was created with three representative cores from each of the ULMS cases as well as from 19 patients with benign uterine leiomyomata. Immunohistochemical (IHC) staining was performed for EGFR, PDGFR, and p53. Negative and positive IHC staining was scored for each marker. Outcome analysis was performed only for ULMS. Survival was determined from the time of initial diagnosis to last follow-up. Twelve (48%) ULMS expressed p53 compared to none of the LMA (P < 0.001), and 15 (60%) ULMS cases showed PDGFR expression compared to 32% of LMA samples (P= 0.08). EGFR expression did not differ between ULMS and LMA groups. ULMS patients with p53 expression had a poorer survival compared to ULMS patients with negative expression (P= 0.07). ULMS tumor stage had the strongest association with overall survival (P= 0.05). Our study supports previous investigations indicating that p53 expression may serve as a prognostic marker for ULMS patients. The difference in PDGFR expression between ULMS and LMA demonstrated a trend toward significance. EGFR was not commonly expressed in ULMS. These uniquely expressed markers may assist in stratifying patients by survival and identify novel therapeutic markers. Clearly, further investigation is needed.

Abstract
Activating BRAF or NRAS mutations have been found in 80% of human sporadic melanomas, but only one of these genetic alterations could be detected in each tumour. This suggests that BRAF and NRAS 'double mutants' may not provide advantage for tumour growth, or may even be selected against during tumorigenesis. However, by applying mutant-allele-specific-amplification-PCR method to short-term melanoma lines, one out of 14 tumours was found to harbour both BRAFV600E and the activating NRASQ61R mutations. On the other hand, analysis of 21 melanoma clones isolated by growth in soft agar from this tumour indicated that 16/21 clones harboured a BRAFV600E, but were wild-type for NRAS, whereas the remaining had the opposite genotype (NRASQ61R/wild-type BRAF). When compared to BRAFV600E clones, NRASQ61R clones displayed reduced growth in soft agar, but higher proliferative ability in vitro in liquid medium and even in vivo after grafting into SCID/SCID mice. These data suggest that NRAS and BRAF activating mutations can coexist in the same melanoma, but are mutually exclusive at the single-cell level. Moreover, the presence of NRASQ61R or BRAFV600E is associated with distinct in vitro and in vivo growth properties of neoplastic cells.

Abstract
The term inflammatory pseudotumour was originally used in a generic fashion for any lesion which simulated a neoplastic condition at a clinical, macroscopic and microscopic level but which was thought to have an inflammatory/reactive pathogenesis. In more recent times, the term has been employed in a more restrictive sense for a mass lesion characterized microscopically by the proliferation of a spindle cell component against a heavy inflammatory infiltrate of mixed composition but usually with a predominance of mature lymphocyte and plasma cells. The spindle cell component has generally been regarded as being of mesenchymal nature and having morphological and phenotypical features consistent with fibroblasts or myofibroblasts, the latter cell being clearly preferred over the former in the more resent reports. The term inflammatory myofibroblastic tumour (IMFT) is the one currently favoured, which proposes the myofibroblastic nature of the process. It is the purpose of this review to bring forth some evidence that the neoplastic spindle cell component of IMFT may be instead derived from the subtype of cells of the accessory immune system that have been variously called fibroblastic reticulum cells, myoid cells, and dictyocytes.

Abstract
Fetal akinesia deformation sequence (FADS) is a rare condition characterized by intrauterine growth retardation (IUGR), congenital limb contractures, pulmonary hypoplasia, hydramnios and craniofacial abnormalities. The present report comprises an autopsy study of three fetuses to illustrate the variable clinical manifestations and neuropathological findings. Fetus 1 had arthrogryposis and no movement on fetal ultrasound examination. Aborted at 21 weeks, the fetus showed micrognathia, bilateral joint contracture with pterygia at the elbow and axilla. Growth retardation and pulmonary hypoplasia were not major features. Neuropathologic examination revealed anterior horn cell loss and lateral corticospinal tract degeneration in spinal cord, with marked muscular atrophy. Fetus 2, 20 weeks' gestation, had fetal akinesia, nuchal thickening, left pleural effusion, and Dandy-Walker malformation on ultrasound examination. Autopsy showed low-set ears, ocular hypertelorism, cleft palate, flexion contractures with pterygia over axilla, elbow and groin, pulmonary hypoplasia, Dandy-Walker malformation, unremarkable spinal cord and skeletal muscle. Fetus 3, 21 weeks' gestation, was aborted for fetal akinesia, neck and limb webbing and severe arthrogryposis. At autopsy, similar facial abnormalities, contracture and pterygia in neck and multiple major joints were found. Borderline pulmonary hypoplasia and severe lumbar scoliosis were also present. The brain, spinal cord and muscle were unremarkable. In these three fetuses, the prenatal ultrasound and autopsy findings were characteristic of FADS. Neurogenic spinal muscular atrophy was the basis of fetal akinesia in Case 1. Dandy-Walker malformation was present in Case 2, but the pathogenetic mechanism of fetal akinesia was not clear as spinal cord and muscle histology appeared normal. The etiology of akinesia was undetermined in Case 3; no extrinsic or intrinsic cause was identified.

Abstract
HOXA11 is a transcription factor implicated in paired appendage development. To identify signatures of evolutionary change in the structural, and putative functional, domains of HOXA11, we studied its evolution in tetrapod and nontetrapod lineages that represent approximately 1.5 billion years of evolutionary time. Here, Hoxa-11 gene proper sequences were determined for frog (Xenopus tropicalis), coelacanth (Latimeria chalumnae), common zebrafish (Danio rerio; Hoxa-11a and Hoxa-11b paralogs), and giant zebrafish (D. aequipinnatus; Hoxa-11b) and aligned against previously published Hoxa-11 sequences of human, mouse, chick, and newt. Based on aligned Hoxa-11 amino acid sequences, the protein was demarcated into three segments: Domains I (N-terminal) and III (homeobox + C-terminal), which varied slightly in rates and patterns of evolution, and a variable, overall hydrophilic region (HyD), which partially overlaps with Domain I. As judged by character reconstructions of HOXA11 Domains I and III, no significant changes in rates of coding sequence evolution occurred in tetrapods (frog and chick), relative to coelacanth (a lobe-finned fish), i.e., across the fin-limb transition. Accelerated rates of Hoxa-11 coding sequence evolution were observed for the mammalian and newt lineages. This was shown to be a gene-specific phenomenon. The duplicated Hoxa-11a and Hoxa-11b genes of zebrafish exhibited accelerated rates of evolution and accumulated substitutions at sites that are conserved among coelacanth and all tetrapods examined. Amino acid sequence comparisons of the HyD of HOXA11 suggested that a putative repressor subdomain, containing stretches of consecutive alanine residues, emerged within the tetrapods. A high degree of nucleotide conservation in the 5' half of the Hoxa-11 intron was observed for tetrapod and nontetrapod lineages. Using electrophoretic mobility shift assays, a 35-bp intron sequence, which is 100% conserved in all Hoxa-11 loci except for the zebrafish Hoxa-11a paralog, was found to bind protein(s) in HeLa and chick whole-cell extracts.

Abstract
The interaction of hydroxylamine (HA) with Arthromyces ramosus peroxidase (ARP) was investigated by kinetic, spectroscopic, and x-ray crystallographic techniques. HA inhibited the reaction of native ARP with H(2)O(2) in a competitive manner. Electron absorption and resonance Raman spectroscopic studies indicated that pentacoordinate high spin species of native ARP are converted to hexacoordinate low spin species upon the addition of HA, strongly suggesting the occurrence of a direct interaction of HA with ARP heme iron. Kinetic analysis exhibited that the apparent dissociation constant is 6.2 mm at pH 7.0 and that only one HA molecule likely binds to the vicinity of the heme. pH dependence of HA binding suggested that the nitrogen atom of HA could be involved in the interaction with the heme iron. X-ray crystallographic analysis of ARP in complex with HA at 2.0 A resolution revealed that the electron density ascribed to HA is located in the distal pocket between the heme iron and the distal His(56). HA seems to directly interact with the heme iron but is too far away to interact with Arg(52). In HA, it is likely that the nitrogen atom is coordinated to the heme iron and that hydroxyl group is hydrogen bonded to the distal His(56).

Abstract
Pneumatosis cystoides intestinalis (PCI) is an uncommon disease manifestation characterized by the presence of air in the bowel wall. PCI is sometimes observed in patients with progressive systemic sclerosis or mixed connective tissue disease but extremely rare in patients with systemic lupus erythematosus (SLE). We here report a patient with SLE who developed PCI after the treatment with intravenous cyclophosphamide (IVCY). This is the first case that association between IVCY and PCI was suggested. A 51-year-old woman with a 24-year history of SLE was admitted to our hospital because of skin ulcers in the lower legs. She had been receiving prednisolone orally. Laboratory findings on the present admission showed a elevated titer of anti-double stranded DNA antibody and positive LE test. She was successfully treated with three pulses of methylprednisolone followed by two IVCY together with vasodilators for her disease activity of SLE including skin manifestation. Just after the second IVCY, abdominal distention was gradually developed without any other abdominal symptoms, including abdominal pain. Abdominal radiography and computed tomography revealed pneumoperitoneum and multiple intramural air collections which involved the ascending colon primarily. Gastrointestinal series, however, showed no evidence of intestinal perforation. The diagnosis of PCI was made radiologically. After she was treated with a combined therapy with intravenous hyperalimentation and breathing with high concentration of oxygen for three weeks, PCI and pneumoperitoneum disappeared. It would be necessary that IVCY is carefully administrated, especially for the patients under the risk of PCI, such as collagen diseases.

Abstract
We report a case of Pneumocystis carinii pneumonia in a patient with acquired immunodeficiency syndrome diagnosed and monitored with polymerase chain reaction (PCR) for Pneumocystis carinii on sputum and measurement of plasma (1-->3)-beta-D-glucan (G-test). Results of both studies paralleled the clinical and radiographic improvement. However, the plasma (1-->3)-beta-D-glucan level remained higher than normal when PCR for Pneumocystis carinii became negative in sputum. Both PCR for Pneumocystis carinii on sputum and measurement of plasma (1-->3)-beta-D-glucan are useful for noninvasive diagnosis and monitoring of Pneumocystis carinii, although further investigation is necessary to quantify their relationship.
