Abstract
Background: Malignant-associated abdominal wall endometriosis (AWE) is a rare pathology, likely to occur in 1% of scar endometriosis. The objectives of this study were to update the evidence on tumor degeneration arising from AWE to notify about the clinical characteristics, the different treatments offered to patients and their outcomes. Methods: A comprehensive systematic review of the literature was conducted. PubMed, Embase and Cochrane Library databases were used. Prospero (ID number: CRD42024505274). Results: Out of the 152 studies identified, 63 were included, which involved 73 patients. The main signs and symptoms were a palpable abdominal mass (85.2%) and cyclic pelvic pain (60.6%). The size of the mass varied between 3 and 25 cm. Mean time interval from the first operation to onset of malignant transformation was 20 years. Most common cancerous histological types were clear cell and endometrioid subtypes. Most widely accepted treatment is the surgical resection of local lesions with wide margins combined with adjuvant chemotherapy. The prognosis for endometriosis-associated malignancy in abdominal wall scars is poor, with a five-year survival rate of around 40%. High rates of relapse have been reported. Conclusions: Endometrial implants in the abdominal wall should be considered as preventable complications of gynecological surgeries. Special attention should be paid to women with a history of cesarean section or uterine surgery.

Abstract
A standardized consensus for the management of cesarean scar pregnancy (CSP) is lacking. The study objective is to evaluate the efficacy, safety and outcomes of the laparoscopic management of CSP as a single therapeutic surgical approach without being preceded by vascular pretreatment or vasoconstrictors injection. This is a retrospective bi-centric study, a case series. Eight patients with a future desire to conceive underwent the laparoscopic treatment of unruptured CSPs. Surgery consisted of "en bloc" excision of the deficient uterine scar with the adherent tissue of conception, followed by immediate uterine repair. The data collected for each patient was age, gestity, parity, number of previous c-sections, pre-pregnancy isthmocele-related symptoms, gestational age, fetal cardiac activity, initial β-human chorionic gonadotropin levels, intra-operative blood loss, blood transfusion, operative time and the postoperative complications, evaluated according to Clavien-Dindo classification. The CSP was successfully removed in all patients by laparoscopy. The surgical outcomes were favorable. All patients with histories of isthmocele-related symptoms reported postoperative resolution of symptoms. The median residual myometrium thickness increased significantly from 1.2 mm pre-operatively to 8 mm 3 to 6 months after surgery. The laparoscopic management seems to be an appropriate treatment of CSP when performed by skilled laparoscopic surgeons. It can be safely proposed as a single surgical therapeutic approach. Larger series and further prospective studies are needed to confirm this observation and to affirm the long-term gynecological and obstetrical outcomes of this management.

Abstract
Ectopic pregnancy is a gynecological emergency. The hCG level, the clinical presentation and the ultrasound remain the key steps for the diagnosis. The criteria tend to be more and more codified to decide on the optimal treatment, however, there is no consensus. The aim of this study was to evaluate the impact of applying a mathematical formula to predict the failure rate of metho-trexate for tubal ectopic pregnancy. A retrospective, monocentric study was conducted on a cohort of 193 patients for whom the formula could be calculated. Regarding our professional practice, the success rate of first-line metho-trexate is 93 %. It would increase to 96 % if the formula had been applied. The use of the formula would also reduce the rate of first-line surgery by 12 %.

Abstract
Contrary to popular belief, we have known for many years that the endometrium is not a sterile environment and is considered to be a low-biomass milieu compared to the vagina. Numerous trials and studies have attempted to establish a valid sampling method and assess its physiological composition, but no consensus has been reached. Many factors, such as ethnicity, age and inflammation, can influence the microbiome. Moreover, it possesses a higher alpha-diversity and, therefore, contains more diverse bacteria than the vagina. For instance, Lactobacillus has been shown to be a predominant genus in the vaginal microbiome of healthy women. Consequently, even if a majority of scientists postulate that a predominance of Lactobacillus inside the uterus improves reproductive outcomes, vaginal contamination by these bacteria during sampling cannot be ruled out. Certain pathologies, such as chronic endometritis, have been identified as inflammation perpetrators that hinder the embryo implantation process. This pro-inflammatory climate created by dysbiosis of the endometrial microbiota could induce secondary inflammatory mediators via Toll-like receptors, creating an environment conducive to the development of endometriosis and even promoting carcinogenesis. However, studies to this day have focused on small populations. In addition, there is no clearly defined healthy uterine composition yet. At most, only a few taxa have been identified as pathogenic. As sampling and analysis methods become increasingly precise, we can expect the endometrial microbiota to be incorporated into future diagnostic tools and treatments for women's health.

Abstract
Chronic pelvic pain (CPP) is one of the main isthmocele symptoms, together with abnormal uterine bleeding and secondary infertility. When patients undergo a laparoscopic niche repair surgery, it is important to determine if they present associated pathologies, such as adenomyosis and/or endometriosis, which are also a cause of CPP. A retrospective study was performed on 31 patients with CPP undergoing a laparoscopic niche repair. The pre-operative ultrasound was analyzed to determine the presence of adenomyosis. Endometriosis was histologically diagnosed. CPP outcome was evaluated at early (3-6 months) and late (12 months) post-operative follow ups. In our population of 31 women presenting CPP, only six of them (19.4%) did not have any associated pathology. In the group of 25 patients with associated pathology, 10 (40%) had no benefit from the reconstructive surgery in terms of CPP at early follow-up (3-6 months) and 8 (32%) in the post-operative period at 12 months. Patients with CPP who undergo niche repair should be carefully selected as CPP does not seem to be a good indication for uterine scar repair in patients with concomitant adenomyosis and endometriosis.

Abstract
Background Septate uterus is the most common uterine malformation found in women presenting poor reproductive history. Hysteroscopic septoplasty (HS) restores the uterine anatomy in a safe procedure. Objectives The goal of our study is to determine the reproductive outcomes after HS of symptomatic septate uterus. Materials and Methods In a retrospective observational single centre study the reproductive outcomes and complications after HS were evaluated in 31 women with symptomatic septate uterus. The patients were separated into two groups according to the symptoms - infertility or recurrent pregnancy loss (RPL). Main outcome measures were the pregnancy and live birth rate and secondarily the complication rate. Furthermore, the results were analysed depending on the need of assisted reproductive techniques (ART). Results The treatment has resulted in an overall pregnancy rate of 71% for both groups. The spontaneous pregnancy rate is 45% and 8 pregnancies resulted from ART (26%). The overall first live birth rate is 51.6%. A decrease has been noticed in the miscarriage rate from 95.24% to 24% (p<0.001) in the overall population. Conclusions In patients with a symptomatic septate uterus hysteroscopic septoplasty is a safe and effective procedure. The favourable results pointing out the benefits of surgery on the reproductive outcomes as well as the relatively simple and safe technique of HS make the intervention attractive.

Abstract
OBJECTIVE Despite being the most important prognostic factor for prolonged overall survival in epithelial ovarian cancer (EOC), the measurement of residual disease is hampered by its subjective character. Additional assessment tools are needed to establish the success of cytoreductive surgery in order to predict patients' prognosis more accurately. The aim of this study is to evaluate the independent prognostic value of perioperative CA125 change in advanced stage EOC patients. STUDY DESIGN We identified all patients who underwent primary cytoreductive surgery for advanced stage (FIGO IIB-IV) EOC between 2008 and 2015, from the Netherlands Cancer Registry. The relative perioperative change in CA125 was categorized into four groups; increase, <50% decline, 50-79% decline and ≥80% decline. Overall survival (OS) was analyzed using Kaplan-Meier survival curves and multivariable cox regression models. RESULTS We included 1232 eligible patients with known pre- and postoperative CA125 serum levels. Patients with a decline of ≥80% in CA125 levels experienced improved OS compared to those with a decline of <50% (univariable Hazard Ratio (HR) 0.45, 95%CI 0.36-0.57). The prognostic effect of perioperative CA125 change was independent of patient- and treatment characteristics, such as the extent of residual disease after cytoreductive surgery (multivariable HR≥80% 0.52(0.41-0.66)). CONCLUSIONS This study shows that the perioperative change in CA125 is an independent prognostic factor for overall survival after primary surgery for EOC patients. This pleads for the use of a combined model, consisting of perioperative CA125 change and the outcome of residual disease, in order to predict the prognosis of EOC patients more accurately.

Abstract
INTRODUCTION The care for patients with epithelial ovarian cancer(EOC) is organised in eight different geographical regions in the Netherlands. This situation allows us to study differences in practice patterns and outcomes between geographical regions for patients with FIGO stage IIIC and IV. METHODS We identified all EOC patients who were diagnosed with FIGO stage IIIC or IV between 01.01.2008 and 31.12.2015 from the Netherlands Cancer Registry. Descriptive statistics were used to summarize treatment and treatment sequence(primary cytoreductive surgery(PCS) or neoadjuvant chemotherapy and interval cytoreductive surgery(NACT-ICS)). Moreover, outcome of surgery was compared between geographical regions. Multilevel logistic regression was used to assess whether existing variation is explained by geographical region and case-mix factors. RESULTS Overall, 6,741 patients were diagnosed with FIGO IIIC or IV disease. There were no differences in the percentage of patients that received any form of treatment between the geographical regions(range 80-86%, P = 0.162). In patients that received cytoreductive surgery and chemotherapy, a significant variation between the geographical regions was observed in the use of PCS and NACT-ICS(PCS: 24-48%, P < 0.001). The percentage of complete cytoreductive surgeries after PCS ranged from 10 to 59%(P < 0.001) and after NACT-ICS from 37 to 70%(P < 0.001). Moreover, geographical region was independently associated with the outcome of surgery, also when adjusted for treatment sequence(P < 0.001). CONCLUSION We observed a significant variation in treatment approach for advanced EOC between geographical regions in the Netherlands. Furthermore, the probability to achieve no residual disease differed significantly between regions, regardless of treatment sequence. This may suggest that surgical outcomes can be improved across geographical regions.

Abstract
Background It is unanimously recognized that the maternal nutritional status at the pregnancy onset influence both short-term and long-term health of the mother and offspring. Among several nutrients, LCPUFA, particularly from the omega-3 family, are of utmost importance. This study was carried out to determine fatty acids profile of maternal erythrocyte membranes in early pregnancy and to identify potential determinants impacting on this status. Methods A cohort of 122 healthy women with a singleton pregnancy was included. Fatty acids were analyzed using gas chromatography. Because of the lack of cutoff values, reference ranges were used to determine fatty acids categories. Results Of concern, our data revealed low monounsaturated and long-chain omega-3 fatty acid status in most participants. More than 75% of Belgian pregnant women exhibited Pal, AO and EPA levels as well as IOM3 values below the laboratory reference ranges. Higher DHA concentrations and IOM3 values were found among foreign-nationality participants, non-smokers and physically active women. With regard to dietary factors, omega-3 supplements and diet seem to be complementary since DHA from supplements (but not from diet) and EPA from diet (but not from supplements) were found to be associated with higher concentrations of DHA and EPA, respectively. Conclusions Our study presents evidence demonstrating that the fatty acid status of most early pregnant women is far from being optimal based on the admitted general reference values. Clinicians should be advice to carefully evaluate and improve this status to guarantee the best possible outcome for both the mother and the baby.

Abstract
BCAR1/p130Cas is a docking protein involved in intracellular signaling pathways and in vitro resistance of estrogen-dependent breast cancer cells to antiestrogens. The BCAR1/p130Cas protein level in primary breast cancer cytosols was found to correlate with rapid recurrence of disease. A high BCAR1/p130Cas level was also associated with a higher likelihood of resistance to first-line tamoxifen treatment in patients with advanced breast cancer. Using antibodies raised against the rat p130Cas protein, we determined by immunohistochemical methods the BCAR1/p130Cas localization in primary breast carcinomas, in tumors of stromal origin, and in non-neoplastic breast tissues. The BCAR1/p130Cas protein was detected in the cytoplasm of non-malignant and neoplastic epithelial cells and in the vascular compartment of all tissue sections analyzed. Immunohistochemistry demonstrated variable intensity of BCAR1/p130Cas staining and variation in the proportion of BCAR1/p130Cas-positive epithelial tumor cells for the different breast carcinomas. Double immunohistochemical staining for BCAR1/p130Cas and estrogen receptor confirmed coexpression in non-malignant luminal epithelial cells and malignant breast tumor cells. The stromal cells in non-malignant tissues and tumor tissues as well as breast tumors of mesodermal origin did not stain for BCAR1/p130Cas. This immunohistochemical study demonstrates a variable expression of BCAR1/p130Cas in malignant and non-malignant breast epithelial cells, which may be of benefit for diagnostic purposes.

Abstract
AIM This study investigates changes in therapy and long-term survival for patients with epithelial ovarian cancer (EOC) in the Netherlands. METHODS All patients with EOC, including peritoneal and fallopian tube carcinoma, diagnosed in the Netherlands between 1989 and 2014 were selected from the Netherlands Cancer Registry. Changes in therapy were studied and related to overall survival (OS) using multivariable Cox regression models. RESULTS A total of 32,540 patients were diagnosed with EOC of whom 22,047 (68%) had advanced stage disease. In early stage, lymph node dissection as part of surgical staging procedures increased over time from 4% in 1989-1993 to 62% in 2009-2014 (P < 0.001). In advanced stage, the number of patients receiving optimal treatment with surgery and chemotherapy increased from 55% in 1989-1993 to 67% in 2009-2014 (P < 0.001). Five-year survival rates improved in both early stage (74% versus 79%) and advanced stage (16% versus 24%) as well as in all patients combined (31% versus 34%). Ten-year survival rates, however, slightly improved in early stage (62% versus 67%) and advanced stage (10% versus 13%) but remained essentially unchanged at 24% for all patients combined. CONCLUSION Despite intensified treatment and staging procedures, long-term survival for women with EOC has not improved in the last 25 years. The observed improvements in 5-year OS reflect a more prolonged disease control rather than better chances for cure. Furthermore, the apparent better long-term outcome, when early and advanced stage patients are analysed separately, is largely due to improved staging procedures and the ensuing stage migration. These effects disappear in a combined analysis of all patients.

Abstract
RATIONALE The European Position Paper on Sinusitis (EPOS) guidelines provide composite criteria to evaluate chronic rhinosinusitis (CRS) control, taking into consideration the severity of patients' symptoms, aspect of nasal mucosa and medical intake as parameters of CRS control. OBJECTIVES To study the degree of CRS control using novel EPOS control criteria at 3-5 years after a functional endoscopic sinus surgery (FESS) and correlate these data to symptoms scores. METHODS Adult CRS patients (n = 560) who had undergone bilateral FESS for chronic inflammatory sinonasal disease 3-5 years prior to the study were included. Patients received a postal questionnaire asking for control items according to EPOS control criteria, visual analogue scale (VAS) scores for total and individual sinonasal symptoms, sinonasal outcome test (SNOT)-22 and Short Form (SF)-36 questionnaires. MEASUREMENTS AND MAIN RESULTS About 19.5% of CRS patients were well controlled, with 36.8% of patients being partly controlled and 43.7% uncontrolled. The levels of control corresponded to mean total VAS, SNOT-22 and SF-36 scores. Subgroup analysis revealed that female gender, aspirin intolerance and revision FESS were associated with higher prevalence of uncontrolled CRS, whereas allergy, asthma and smoking status did not alter the percentage of patients in each category of control. In 81 patients attending the outpatient clinic, nasal endoscopy changed classification in only four patients (4.9%). CONCLUSIONS Based on the novel EPOS control criteria, at least 40% of CRS patients are uncontrolled at 3-5 years after FESS. Therefore, better treatment strategies leading to higher disease control are warranted in CRS care.

Abstract
BACKGROUND Treatment for allergic rhinitis (AR) aims at reducing the burden of allergic inflammation, either by suppression of the nasal inflammation with pharmacotherapy or by inducing tolerance via immunotherapy (IT). At present, we lack information on the comparison between the degree of symptom control in AR patients treated with IT and those on pharmacotherapy. AIMS An observational study was conducted evaluating the degree of symptom control, the total and individual nasal symptom severity and current medication use at 3 years after starting either pharmacotherapy or subcutaneous immunotherapy (SCIT) for AR. METHODS A total number of 800 patients diagnosed with AR between October 2007 and February 2010 at the Ear, Nose and Throat Unit and Allergology Clinical Department of the University Hospitals of KU Leuven, Belgium, were included. Among these patients, 120 had been started on IT at the time of their initial visit, and 680 were prescribed guideline-based pharmacotherapy. In 2013, patients were sent a questionnaire asking for the current severity of nasal symptoms using a visual analogue scale (VAS) score, duration of nasal symptoms and presence or absence of abnormal sleep, impairment of daily activities, sport, leisure, impaired functioning at work/school, troublesome symptoms, and current medication use. A VAS score for total nasal symptoms (TNS) was used to distinguish between controlled and uncontrolled AR. RESULTS An overall response rate of 54%. At 3 years after the initiation of the treatment, the IT group showed lower VAS scores for TNS than the pharmacotherapy group, with lower percentages of patients having a VAS score of equal or higher than 5. The IT group consisted of more patients with mild AR than the pharmacotherapy group despite the higher percentage of polysensitization at the onset of treatment in the IT group. 18% of the IT patients met the criteria of persistent AR whereas this was 51% amongst non-IT patients. Interestingly, 70% of IT patients did not use any medical treatment for AR anymore, whereas 61% of pharmacotherapy patients were still on medical treatment. CONCLUSIONS This observational study demonstrates that IT is associated with higher control of AR, reduced symptom severity and reduced medication use at 3 years after the onset of treatment. Therefore, this real-life study reinforces the clinical value of immunotherapy in allergic rhinitis.

Abstract
UNLABELLED Draf III frontal sinusotomy: influence of patient characteristics on outcome. OBJECTIVE To identify positive and negative predictive outcome factors for the Draf III procedure based on the experience of a single center. METHODS Seventy-two patients who underwent a Draf III procedure between 2005 and 2011 at the ENT department of University Hospitals Leuven were included. Patient demographics, history of frontal sinus surgery, clinical features, and computed tomographic evaluations were reviewed and analyzed for associations with symptom control and endoscopic outcome. RESULTS The mean age was 48 years (16-82 years), and the male-to-female-ratio was 2:1. Major indications were chronic rhinosinusitis (with or without nasal polyps) and mucoceles. Supplementary frontal (recess) cells were found in the majority of patients. Osteoneogenesis was present in one out of four patients. At the end of follow-up (mean 35 months), the neo-ostium patency rate was 89%. Stenosis or closure of the neo-ostium was seen in 11% of patients, and 15% of patients required revision surgery. Subjective improvement was reported by 88%. CONCLUSION The results of Draf III frontal sinusotomy were positive in the long term. Previous frontal sinus surgery, the presence of allergy or aspirin-exacerbated respiratory disease (AERD), asthma, smoking, and variants in frontal recess anatomy did not affect outcome. Osteoneogenesis and chronic mucosal inflammation could be controlled by creating a large drainage pathway.

Abstract
Gestational trophoblastic diseases include placental pathologies comprising fertilization abnormalities (hydatidiform moles) and malignant lesions (choriocarcinoma, placental site trophoblastic tumor and epithelioid trophoblastic tumor). Due to their low incidence and heterogeneity, their diagnosis, management and treatment are not always optimal. Following the example of other European countries, a national registration system with two reference centers has been set up to guide physicians and patients and to propose individualized management. The centers offer their expertise through a systematic centralised pathology review by a panel of experts. HCG values are plotted in regression curves. In case of gestational trophoblastic neoplasia, an imaging work-up is proposed, from which the FIGO score and stage are derived and will guide the choice of treatment. Belgian centers offer a multidisciplinary approach, in partnership with the referent physician. More information for practitioners and patients is available on a web site: www.mole-chorio-bgog.eu, which also harbours a forum of discussion.

Abstract
State-of-the-art documents like ARIA and EPOS provide clinicians with evidence-based treatment algorithms for allergic rhinitis (AR) and chronic rhinosinusitis (CRS), respectively. The currently available medications can alleviate symptoms associated with AR and RS. In real life, a significant percentage of patients with AR and CRS continue to experience bothersome symptoms despite adequate treatment. This group with so-called severe chronic upper airway disease (SCUAD) represents a therapeutic challenge. The concept of control of disease has only recently been introduced in the field of AR and CRS. In case of poor control of symptoms despite guideline-directed pharmacotherapy, one needs to consider the presence of SCUAD but also treatment-related, diagnosis-related and/or patient-related factors. Treatment-related issues of uncontrolled upper airway disease are linked with the correct choice of treatment and route of administration, symptom-oriented treatment and the evaluation of the need for immunotherapy in allergic patients. The diagnosis of AR and CRS should be reconsidered in case of uncontrolled disease, excluding concomitant anatomic nasal deformities, global airway dysfunction and systemic diseases. Patient-related issues responsible for the lack of control in chronic upper airway inflammation are often but not always linked with adherence to the prescribed medication and education. This review is an initiative taken by the ENT section of the EAACI in conjunction with ARIA and EPOS experts who felt the need to provide a comprehensive overview of the current state of the art of control in upper airway inflammation and stressing the unmet needs in this domain.

Abstract
Draf in 1991. The procedure--which is also known as the modified endoscopic Lothrop procedure--aims to create the largest possible anteroposterior and lateral to lateral opening between both frontal sinuses and the nasal cavities. This requires the resection of the medial floor of both frontal sinuses, the intersinus septum and the superior nasal septum. The authors present a retrospective study including a cohort of 120 patients who underwent surgery in six Belgian university ENT departments. Mean follow-up was 24.6 months (range: 5-36 months). This paper describes the surgical procedure and reviews the indications, comorbidities, outcomes and complications of the type III frontal sinusotomy. Some correlations are also established with the data published in the worldwide literature. The authors conclude that the Draf III is a demanding procedure requiring considerable expertise in endoscopic sinus surgery. The procedure is effective with a success rate of 87.5%. Indeed, 12.5% of patients only experienced closure of the neoostium while 20% of all the patients had unchanged or worse symptomatology. The percentage of post-operative complications is 7.5%. All complications were managed successfully.

Abstract
The ability of Bluetongue virus serotype 8 (BTV-8) originating from the 2006 European outbreak to cross the ovine placenta during early and mid gestation was investigated in two separate experiments. In the first experiment, 16 ewes were infected with BTV-8 at 70-75 days gestation. The foetuses were collected at 18-19 days after infection (dpi). BTV-8 could be isolated from at least two organs of 19 out of 40 lambs and from 11 out of 16 infected ewes. In the second experiment, 20 BTV-8 infected ewes in early gestation (day 40-45) were euthanized at 10 days (10 ewes) or 30 days (10 ewes) after infection. The presence of BTV could be demonstrated in two foetuses from two ewes at 10 dpi and in 4 foetuses from four ewes at 30 dpi. The main pathological findings in the foetuses in mid gestation were meningo-encephalitis and vacuolation of the cerebrum. In the foetuses early at gestation, haemorrhages in various foetal tissues and necrosis and haemorrhages in the placentomes were found. These experiments demonstrate for the first time the presence of infectious BTV in lamb foetuses at different stages of gestation, combined with a difference in transmission rate depending on the gestation stage. The high transmission rate found at mid term gestation (69%) makes our model very suitable for further research into the mechanisms of transplacental transmission and for research into the reduction of this route of transmission through vaccination.

Abstract
BACKGROUND There is growing evidence on the importance of experiences of stressful events in the development of psychopathology. This study aimed to investigate the role of stressful events in the continuity of internalizing and externalizing problems, as well as the cross-influence of these problems from early childhood to late adolescence. METHOD Data came from a general population sample of 396 children followed from the ages of 3 to 18 years. Parent-ratings of internalizing and externalizing problems at ages 3, 5, 10 and 18 years were used. Parents also reported on the presence of stressful events between the ages of 3 and 5 years, and 5 and 10 years. Adolescent reports on stressful events over the ages of 10-18 years were used. Structural equation models were used to disentangle/analyse the role of stressful events in the development of internalizing and externalizing problems. RESULTS From the age of 3 years onwards externalizing symptoms predicted experiences of stressful events. In turn, these experiences predicted later externalizing problems. Stressful events also explained part of the continuity of internalizing problems from the age of 10 years onwards, but not during childhood. From childhood onwards, cross-influences from externalizing problems to subsequent internalizing problems were found to run through stressful events. Only in adolescence cross-influences from internalizing problems to externalizing problems were found, again via stressful events. CONCLUSIONS From childhood onwards to late adolescence, stressful events play a significant role in both the continuity and the co-occurrence of externalizing and internalizing problems. Theoretical and methodological implications of these findings are discussed.

Abstract
About 70-80% of breast cancers express estrogen receptor alpha (ER-alpha), and estrogens play important roles in the development and growth of hormone-dependent tumors. Together with lymph node metastasis, tumor size, and histological grade, ER status is considered as one of the prognostic factors in breast cancer, and an indicator for hormonal treatment. To investigate genes and pathways that are associated with ER status and epithelial cells in breast tumor, we applied laser capture microdissection (LCM) technology to capture epithelial tumor cells from 28 lymph node-negative breast tumor samples, in which 17 patients had ER-alpha+ tumors, and 11 patients have ER-alpha- tumors. Gene expression profiles were analysed on Affymetrix Hu133A GeneChip. Meanwhile, gene profiles using total RNA isolated from bulk tumors of the same 28 patients were also generated. In total, 146 genes and 112 genes with significant P-value and having significant differential expression between ER-alpha+ and ER-alpha- tumors were identified from the LCM data set and bulk tissue data set, respectively. A total of 61 genes were found to be common in both data sets, while 85 genes were unique to the LCM data set and 51 genes were present only in the bulk tumor data set. Pathway analysis with the 85 genes using Gene Ontology suggested that genes involved in endocytosis, ceramide generation, Ras/ERK/Ark cascade, and JAT-STAT pathways may play roles related to ER. The gene profiling with LCM-captured tumor cells provides a unique approach to study epithelial tumor cells and to gain an insight into signaling pathways associated with ER.

Abstract
OBJECTIVE To review the nature of the presentation of neurosyphilis, the value of diagnostic tests, and the classification of the disease. METHODS A retrospective review was carried out of the records of patients who had been identified as possible cases of neurosyphilis by a positive FTA-abs test in the CSF. The review extended over 10 years at a single hospital which served a population of mixed ancestry in a defined catchment area in the Western Cape province of South Africa. Patients were placed in predefined diagnostic categories, and clinical, radiological, and laboratory features were assessed. RESULTS 161 patients met diagnostic criteria for neurosyphilis: 82 presented with combinations of delirium and dementia and other neuropsychiatric conditions, and the remainder had typical presentations such as stroke (24), spinal cord disease (15), and seizures (14). The average age of presentation ranged from 35.9 to 42.6 years in the different categories of neurosyphilis. Of those followed up, 77% had residual deficits from their initial illness. Cerebrospinal fluid (CSF) VDRL was positive in 73% of cases. CONCLUSIONS The diagnosis of neurosyphilis can be made with reasonable certainty if there is an appropriate neuropsychiatric syndrome associated with a positive CSF VDRL. If the VDRL is negative, a positive FTA-abs in an appropriate clinical setting, associated with raised CSF cell count, protein, or IgG index, is a useful method of identifying neurosyphilis. Tabes dorsalis has become uncommon, but this is likely to be the only manifestation of neurosyphilis that has been altered during the antibiotic era.

Abstract
BCAR1/p130Cas is a docking protein involved in intracellular signaling pathways and in vitro resistance of estrogen-dependent breast cancer cells to antiestrogens. The BCAR1/p130Cas protein level in primary breast cancer cytosols was found to correlate with rapid recurrence of disease. A high BCAR1/p130Cas level was also associated with a higher likelihood of resistance to first-line tamoxifen treatment in patients with advanced breast cancer. Using antibodies raised against the rat p130Cas protein, we determined by immunohistochemical methods the BCAR1/p130Cas localization in primary breast carcinomas, in tumors of stromal origin, and in non-neoplastic breast tissues. The BCAR1/p130Cas protein was detected in the cytoplasm of non-malignant and neoplastic epithelial cells and in the vascular compartment of all tissue sections analyzed. Immunohistochemistry demonstrated variable intensity of BCAR1/p130Cas staining and variation in the proportion of BCAR1/p130Cas-positive epithelial tumor cells for the different breast carcinomas. Double immunohistochemical staining for BCAR1/p130Cas and estrogen receptor confirmed coexpression in non-malignant luminal epithelial cells and malignant breast tumor cells. The stromal cells in non-malignant tissues and tumor tissues as well as breast tumors of mesodermal origin did not stain for BCAR1/p130Cas. This immunohistochemical study demonstrates a variable expression of BCAR1/p130Cas in malignant and non-malignant breast epithelial cells, which may be of benefit for diagnostic purposes.

Abstract
Variation among vascular plants in the initiation and patterning of leaves results in a diverse array of leaf shape, including the strap-like leaf of many grasses and the broad lamina of most eudicots. Recent findings highlight the importance of interactions between the shoot apical meristem (SAM) and developing leaf primordia in axis specification and the establishment of leaf shape. Global regulators of epigenetic states have been implicated in these interactions and may play a role in distinguishing founder cells and stem cells within the SAM.

Abstract
We report 3 cases of spontaneous rupture of pancreaticoduodenal arteries (PDA). In the first case, an aneurysm of the PDA was demonstrated with stenosis of the celiac trunk; in the second case occlusion of the hepatic artery was shown. In both cases, arterial pancreatic arcades were enlarged and blood flow was retrograde from the superior mesenteric artery. Local high intravascular pressure due to retrograde blood flow through the arterial pancreatic arcades was thought to be the cause of aneurysm development and arterial rupture which necessitated surgical intervention. The third patient presented with a mycotic aneurysm that could be treated by intra-arterial embolization. The characteristics of this rare affliction are discussed, as is the treatment which first entails percutaneous embolization.

Abstract
BACKGROUND Urokinase-type plasminogen activator (uPA), its receptor (uPAR) and plasminogen activator inhibitors (PAI-1 and PAI-2), all play important roles in tumour invasion and metastasis. The tumour levels of the components of the urokinase-type plasminogen activator system (uPA-system) may help to identify individuals with a poor prognosis in postoperative non-small-cell lung cancer (NSCLC) patients. PATIENTS AND METHODS The levels of uPA, uPAR PAI-1 and PAI-2 were measured by enzyme-linked immunosorbent assay (ELISA) in triton-extracts, prepared from 88 NSCLC tissues (stage I-IIIa) and 74 normal lung tissues from the same patients. RESULTS The expression levels of uPA, uPAR, PAI-1 and PAI-2 were significantly higher in tumour tissues as compared to their normal equivalents (all, P < 0.0001). Significant relations were found between gender and uPA (P = 0.04) or uPAR (P < 0.001), and between PAI-2 and pathological stage (P = 0.03). For none of the studied factors of the uPA-system a significant relation with survival was found, neither in all patients, nor in the subgroups of patients with squamous-cell lung carcinoma or adenocarcinoma. CONCLUSIONS The expression levels of the components of the uPA-system were higher in NSCLC tissue as compared to normal lung tissue, but there were no significant relationships between their levels and survival.

Abstract
Coelomic fluid of Eisenia foetida earthworms contains a 42-kDa protein named coelomic cytolytic factor 1 (CCF-1) that was described previously to be involved in cytolytic, opsonizing, and hemolytic properties of the coelomic fluid. Cloning and sequencing of CCF-1 reveal significant homology with the putative catalytic region of beta-1,3- and beta-1,3-1,4-glucanases. CCF-1 also displays homology with coagulation factor G from Limulus polyphemus and with Gram-negative bacteria-binding protein of Bombyx mori silkworm, two proteins involved in invertebrate defense mechanisms. We show that CCF-1 efficiently binds both beta-1,3-glucan and lipopolysaccharide. Moreover, CCF-1 participates in the activation of prophenoloxidase cascade via recognition of yeast and Gram-negative bacteria cell wall components. These results suggest that the 42-kDa CCF-1 protein of E. foetida coelomic fluid likely plays a role in the protection of earthworms against microbes.

Abstract
The prognostic value of epidermal growth factor receptor (EGFR) expression and its biological role in estrogen receptor-positive (ER+) and ER-negative (ER-) primary breast cancer is controversial. In this study, distributions of ER, progesterone receptor and EGFR have been established using immunohistochemistry in both primary breast tumors and their matched axillary lymph node metastases of 26 patients or their matched distant metastases of 2 patients. In addition, 5 patients with bilateral breast cancer were studied. ER+ tumor cells were detected in 22 (69%) and EGFR+ tumor cells were detected in 11 (34%) primary breast carcinomas. Expression of ER and EGFR was inverse regarding the individual tumor cells in both primary tumors and metastases. Relationship of EGFR expression with poorly differentiated and large breast tumors was observed. Furthermore, primary tumors with a predominant lobular component were ER+ and, with one exception, EGFR-. Invasive ductal carcinomas were more frequently EGFR+. No apparent differences in receptor expression were observed between primary tumors and lymph node metastases or chronously or metachronously occurring bilateral breast cancers. Only one ER+ primary tumor showed a switch to EGFR expression in the involved lymph node. Our study shows that a shift in receptor phenotype between primary tumors and lymph node metastases is a rare event and, thus, additional analyses of involved lymph nodes will not likely serve as a better predictor for response to anti-estrogen therapy. We conclude that expression of EGFR is not a prerequisite for development of metastases.

Abstract
The prevalence of Helicobacter pylori gastritis in 36 patients with a perforated ulcer undergoing endoscopy prior to or at least 2 months after perforation was 56%, intermediate between that of age and sex matched healthy blood donors (36%) who had measurement of circulating antibodies to Helicobacter pylori and of ulcer patients without perforation matched for age, sex and ulcer location (86%). In the 20 patients with Helicobacter pylori gastritis, 8 had a history of peptic ulcer and 7 of 9 patients with a follow-up of at least 12 months and no preventive treatment had a symptomatic relapse. The group of patients without infection included 6 young patients (< 40) who did not use non steroidal anti-inflammatory drugs and 10 older patients (> 60): 9 used non steroidal anti-inflammatory drugs and seven had a normal gastric mucosa on biopsy. One patient without Helicobacter pylori had a second perforation, the only relapse in this group. We conclude that patients with perforated ulcers are a heterogeneous group with a recurrent ulcer disease mainly in patients with Helicobacter pylori.

Abstract
Distribution of estrogen (ER), progesterone (PR) receptors, and epidermal growth factor (EGF) receptors was assayed by dual staining immunohistochemistry on 28 selected cytosolic ER-positive breast carcinomas and 22 nonmalignant breast tissues. ER-positive tumor cells were detected in 26 (93%) and EGF receptor positive tumor cells were detected in 7 (25%) carcinomas. In five tumors both ER and EGF receptors were detected but localized in distinct tumor cells. Only in one case of ductal carcinoma in situ co-expression was observed in a subset of tumor cells. In contrast, simultaneous expression of ER/PR and EGF receptors was observed in non-neoplastic ductal remnants in the majority of the carcinomas and the fibroadenomas. In addition, double-positive cells were occasionally detected in luminal epithelial cells of normal breast tissue and mastopathies. This study shows that ER/PR and EGF receptors in breast tumor cells are inversely related at the single cell level. However, demonstration of ER/PR and EGF receptors in individual normal luminal cells shows that expression is not mutually exclusive.

Abstract
The induction of chromosome and/or genome mutations during the first steps of skin carcinogenesis was followed in male NMRI mice, treated with a 'two-stage' [9,10-dimethyl-1,2-benzanthracene (DMBA) + phorbol-12-myristate-13-acetate (TPA)], or a 'three-stage' [DMBA+methyl methanesulphonate (MMS) + phorbol-12-retinoate-13-acetate (RPA)] protocol. The scoring of micronuclei (MN) in basal and suprabasal keratinocytes allows a relatively fast in vivo estimation of clastogenic and aneugenic effects of various compounds and treatments. Relevant stages were then further analysed by karyotyping the in vivo treated keratinocytes that were allowed to divide during short in vitro cultivation. DMBA used as initiator in both protocols was able to induce MN. The well-known clastogen MMS had an acute but transient effect on MN induction when used alone or as convertor in the three-stage protocol. Neither the propagator RPA, nor the 'full-promotor' TPA, which can carry out conversion as well as propagation, induced statistically significant numbers of MN when applied on mouse skin. Combined treatments, DMBA+MMS and MMS+RPA, showed higher MN frequencies than when MMS treatments were given alone. The full carcinogenic protocols showed significant frequencies of MN but the time points of appearance differed, indicating that the accumulation of aberrations could be more important than the order of appearance. Karyotypic analysis of those stages where the MN assay detected genome and/or chromosome aberrations revealed no specific loss of chromosomes that might be directly related to the carcinogenic process. When chromosome loss and aberrations were both taken into consideration together, chromosomes 7 and 11 and surely 9, 17 and 18 were more frequently involved than others.

Abstract
A case report and review of literature. Four types of neoplastic dissemination exist in presence of ovarian adenocarcinomas. Commonly, these tumors metastasize along intraperitoneal ways or lymphatic channels. Less frequently, the tumors are invading surrounding organs by direct extension. Rarely, there is a hematogenous dissemination. The observation of a gastric metastasis is reported; we consider it as a hematogenous one. Reviewing the literature, we find few similar cases. Gastric metastases originate more frequently from malignant melanomas, adenocarcinomas of the breast and bronchogenic tumors.

Abstract
A rare case of intestinal muscular layers agenesis is described. Ten other cases were founded in the literature and are briefly reported. Association of ischemia and congenital abnormality of the muscular layers is probably the cause of the perforation. Prognosis is very bad: all the children with clinical symptoms (occlusion or perforation) died.
