Abstract
INTRODUCTION AND HYPOTHESIS The objective was to present endoscopic images of a meshoma and describe the complete excision of a complicated mesh after sacrocolpopexy (SCP) using a combined vaginal-endoscopic technique. METHODS We present a video documentation of an innovative technique. A 58-year-old woman was referred with painless, foul-smelling vaginal discharge and recurrent vaginal mesh erosions. She had undergone a laparoscopic SCP 12 years ago and her symptoms had begun 5 years ago. A pre-operative MRI scan revealed a cuff meshoma and an inflammatory sinus around the mesh extending from the cuff to the sacral promontory. Under general anesthesia, a 30° hysteroscope was inserted transvaginally into the sinus, where the retained mesh was seen in the form of a shrunken meshoma, and then the mesh arms were recognized extending cephalad into a sinus tract. Under direct endoscopic visualization, the mesh was carefully mobilized at its highest point with the use of laparoscopic grasping forceps. Then, the mesh was dissected with hysteroscopic scissors in close proximity to the bone. No peri-operative complications were recognized. RESULTS A combined vaginal-endoscopic approach was successfully used to remove an eroded mesh and cuff meshoma after SCP. CONCLUSION This procedure offers a minimally invasive, low-morbidity, and rapid-recovery approach.

Abstract
AIMS The European Society of Cardiology (ESC) EURObservational Research Programme (EORP) Non-ST-segment elevation myocardial infarction (NSTEMI) Registry aims to identify international patterns in NSTEMI management in clinical practice and outcomes against the 2015 ESC Guidelines for the management of acute coronary syndromes in patients presenting without ST-segment-elevation. METHODS AND RESULTS Consecutively hospitalised adult NSTEMI patients (n = 3620) were enrolled between 11 March 2019 and 6 March 2021, and individual patient data prospectively collected at 287 centres in 59 participating countries during a two-week enrolment period per centre. The registry collected data relating to baseline characteristics, major outcomes (in-hospital death, acute heart failure, cardiogenic shock, bleeding, stroke/transient ischaemic attack, and 30-day mortality) and guideline-recommended NSTEMI care interventions: electrocardiogram pre- or in-hospital, pre-hospitalization receipt of aspirin, echocardiography, coronary angiography, referral to cardiac rehabilitation, smoking cessation advice, dietary advice, and prescription on discharge of aspirin, P2Y12 inhibition, angiotensin converting enzyme inhibitor (ACEi)/angiotensin receptor blocker (ARB), beta-blocker, and statin. CONCLUSION The EORP NSTEMI Registry is an international, prospective registry of care and outcomes of patients treated for NSTEMI, which will provide unique insights into the contemporary management of hospitalised NSTEMI patients, compliance with ESC 2015 NSTEMI Guidelines, and identify potential barriers to optimal management of this common clinical presentation associated with significant morbidity and mortality.

Abstract
In educational and clinical settings, few norm-referenced tests have been utilized until now usually focusing on a single or a few language subcomponents, along with very few language rating scales for parents and educators. The need for a comprehensive language assessment tool for preschool and early school years children which could form the basis for valid and reliable screening and diagnostic decisions, led to the development of a new norm-referenced digital tool called Logometro®. The aim of the present study is to describe Logometro® as well as its psychometric characteristics. Logometro® evaluates an array of oral language skills across the different language domains such as phonological awareness, listening comprehension, vocabulary knowledge (receptive and expressive), narrative speech, morphological awareness, pragmatics, as well emergent literacy skills (letter sound knowledge and invented writing) in Greek-speaking 4–7 years old children. More specifically, Logometro® has been designed in order to: (a) map individual language development paths as well as difficulties, (b) provide a descriptive profile of children’s oral language and emergent literacy skills, and (c) assist in the identification of children who are at risk for Developmental Language Disorder (DLD) or Specific Learning Disabilities (SLD). The sample consisted of 926 children aged from 4 to 7 years, which were recruited from diverse geographical provinces and represented a variety of socioeconomic backgrounds in Greece. Eight hundred participants were typically developing children (Nboys = 384 and Ngirls = 416), 126 children (NSLI = 44 and NSLD = 82) represented children with Special Educational Needs, and 126 children were typically developing peers matched for gender and age with the clinical groups. The administration lasted 90 min, depending on the participant’s age and competence. Validity (construct, criterion, convergent, discriminant, and predictive) as well as internal consistency and test–retest reliability were assessed. Results indicated that Logometro® is characterized by good psychometric properties and can constitute a norm-referenced battery of oral language and emergent literacy skills. It could be used to inform the professionals as well as the researchers about a child’s language strengths and weaknesses and form the basis on which they can design an appropriate individualized intervention if needed.

Abstract
Intoxication from calcium channel blockers exhibits almost 50% mortality rates. Amlodipine is a long-acting dihydropyridine and inappropriate dosage poses a great threat for profound vasodilation, hypotension, and refractory vasopressor-resistant shock. A 72-year-old woman with unremarkable medical history presented to the emergency department due to amlodipine overdose after a suicide attempt attributed to COVID-19 pandemic severe anxiety disorder. Vital signs at presentation: heart rate 82 beats/ min, arterial pressure 72/55 mmHg, and oxygen saturation 98%. Resuscitation was initiated with intravenous infusion of normal saline 0,9%, noradrenaline, and calcium chloride, while activated charcoal was orally administrated; however, blood pressure remained at 70/45 mmHg. Abruptly, she experienced acute pulmonary edema and was finally intubated. We commenced high-dose insulin infusion with Dextrose 10% infusion to maintain euglycemic hyperinsulinemia. Hemodynamic improvement occurred after 30 min, systolic blood pressure raised to 95 mmHg, and decongestion was achieved with intravenous furosemide. Insulin effect was dose-dependent and patient’s hemodynamic status improved after insulin uptitration. Eight days later, the patient was weaned from the mechanical ventilation and she was successfully discharged after 14 days. High-dose intravenous infusion of insulin up to 10 units/kg per hour appears as an inotropic agent possibly through alterations in myocardial metabolism of fatty acids and augmentation of insulin secretion and uptake. This regimen possibly exhibits additional vasotropic properties. We conclude that euglycemic hyperinsulinemia is a potentially advantageous treatment in CCB toxicity.

Abstract
Oral language and narrative skills constitute very critical factors for children's academic performance and social competence. The aim of the present study was to investigate the developmental patterns of story retelling, as well as the relationship between oral language and story retelling in preschool and primary school children. Two hundred and thirty-seven Greek-speaking children (4-5, 5-6 and 6-7 years old) participated in the study. Vocabulary knowledge, phonological awareness, morphological awareness skills and pragmatics were examined through a standardized psychometric test. Story retelling was measured by inviting the children to listen to a story and then retell it. Children's narratives were evaluated according to microstructure (use of conjunctions and lexical cohesion) and macrostructure (story grammar and temporal sequencing) criteria. The results showed that children performed better as they got older across all the oral language and story retelling tasks. Structural equation modeling revealed that vocabulary skills stand out as a stable predictor across all the three age groups. A new finding was also demonstrated, highlighting that morphological awareness, phonological awareness skills and pragmatics work together with vocabulary skills in diverse patterns at different points of a child's development, in order to support his/her ability to retell a story.

Background/Introduction
Atrial fibrillation (AF) is a common heart arrhythmia predominantly in advanced age patients and in diabetic’s type II (DMPII). Even if the risk of stroke in AF in DMPII is relative high, 25% of AF patients remains undiagnosed and also cryptogenic AF is very common in the diabetic population. During a 12-month study project, podiatrists and podologists performed foot pulse-checks in their routine podiatry assessment, when encountering visual symptoms that suggest an underlying circulatory disorder in diabetics. This simple non-invasive method aims to increase screening and diagnosis of AF from allied health professionals, in order to reveal patients with previously undiagnosed AF and patients with cryptogenic Af, challenging the potential reduction of AF complications and mainly of stroke.
Purpose
Early detection of AF in diabetics from allied health professionals during routine podiatry assessment. Revealing of previously undiagnosed AF contributes to stroke and other AF complications incidence reduction in the diabetics population.
Methods
During a 12-month study, 2 podiatrists and 6 podologists performed foot pulse-checks on diabetics, during their annual foot screening appointments, since they have been trained from medical doctors to spot rhythm abnormalities during pulse palpation of the foot arteries. They have been also trained to confirm their pulse palpation evidence thought Doppler ultrasound wave assessments during evaluation of arterial blood supply (anterior-posterior tibial arteries and ramifications) of the diabetic foot. During the study 300 diabetics (mean age 60 years old, 180 males, 120 females) had their feet pulse-tested. Spss statistical software had been used.
Results
17% of diabetics during foot pulse-checks presents undiagnosed AF. There was no statistically significant difference (p < 0.05) between sex (males and females AF screening percents were similar).
Conclusion(s)
Early detection and properly managed during AF screening reduces AF complications and specifically stroke incidence. Opportunistic podiatric detection of previously undiagnosed and cryptogenic AF from allied professionals is a non invasive, safe, fast and economic method with potential contributions in this direction. More studies must be designed in order to support the routine podiatry assessment, as a useful Screening diagnostic tool of AF for reducing cardiovascular complications incidence in diabetics but also in the general population.

Abstract
A typical bile duct branching patterns represent one of the major causes of bile duct injury (BDI) during laparoscopic cholecystectomy (LC). The most common classified variations of bile duct branching, involve the right posterior sectoral duct (RPSD) and its joining with the right anterior or left hepatic duct. Variant bile duct anatomy can rarely be extremely complex and unclassified. This report describes an extremely rare case of an isolated injury to an aberrant right hepatic duct formed by the joining of ducts from segments V, VII, and VIII draining into the cystic duct (cysticohepatic duct) during LC, associated with an inferior RPSD opening to left hepatic duct. Detailed evaluation of both endoscopic and magnetic cholangiograms established the diagnosis. Bile duct injury was subsequently managed surgically by a demanding Roux-en-Y hepaticojejunostomy. This extremely rare case aims to serve as a useful reminder of the consistent inconsistency of biliary anatomy, alerting surgeons to beware of variant bile duct branching patterns during open or LC that constitute a dreadful pitfall for severe and life-threatening bile duct injuries.

We enrolled a total of 153 patients as follows: 49 patients with STEMI, 35 NSTEMI, 38 with unstable angina (UA), 15 with stable CAD (SCAD) and 16 non-CAD (controls). Flow cytometry analysis was used to quantify circulating apoptotic (annexin+) and non-apoptotic endothelial cell (EMP), red blood cell (RMP) and platelet (PMP) derived microparticles. Circulating C-reactive protein (hsCRP) levels and cardiac troponin I (cTnI) were also assessed. Brachial FMD was also determined as a marker of endothelial function.
Results
There was a stepwise increase in the total number of EMP, RMP and PMP in patients with ACS (STEMI/NSTEMI) compared to UA, SCAD and non-CAD patients. This was mainly explained by the increase in the number of apoptotic EMP, RMP and PMP (a-c), while there were no significant differences in the level of apoptotic EMP, RMP or PMP between patient subgroups (not shown). There was no association between circulating levels of apoptotic or non-apoptotic EMP, RBP or PMP with hsCRP (p=NS for all). Apoptotic EMP only were negatively associated with brachial FMD (rho=−0.185, p=0.04) and positively with cTnI levels (rho= 0.307, p<0.0001).
Conclusions
Circulating apoptotic (but not non-apoptotic) MP are increased in patients with ACS. A negative association is observed between the numbers of circulating apoptotic EMP only and systemic endothelial function. The biological role of circulating apoptotic microparticles' in the pathogenesis of ACS merits further investigation.

Abstract
Abstract
Background
Circulating microparticles (MP) are surrogate biomarkers of atherosclerosis and are elevated in acute coronary syndromes (ACS) but its exact biological role remains unknown.
Purpose
To explore the diagnostic and biological significance of circulating apoptotic MP signature in patients with ACS.
Methods
We enrolled 122 ACS patients: n=38 with unstable angina (UA), n=49 with STEMI, 35 with NSTEMI. Flow cytometry analysis was used to quantify circulating apoptotic (annexin+) endothelial cell (EMP), red blood cell (RMP) and platelet (PMP) derived microparticles. Endothelial function was estimated with flow mediated dilation (FMD), and inflammatory status with C-reactive protein (hsCRP).
Results
The association between EMP, RMP and PMP is shown on a cloud plot (A). Using an unbiased approach, we performed hierarchical clustering (A) of the total population of patients with ACS by using the circulating levels of EMP, RMP and PMP (B). Hierachical clustering identified two discreet clusters of patients (Cluster A and B) without any differences in the presence of traditional risk factors (not shown), but significant differences in the distribution of ACS type (C). STEMI subtype (a surrogate for definite plaque rupture) was significantly increased in Cluster B, which also had significantly decreased FMD (D), but not hsCRP (p=NS).
Conclusions
Apoptotic MP are involved in the pathogenesis of acute coronary syndromes via promotion of endothelial dysfunction and plaque rupture. The diagnostic and/or predictive value of microparticles' profiling for plaque vulnerability should be explored in future studies.

Abstract
Bacterial resistance has become a worldwide concern, particularly after the emergence of resistant strains overproducing carbapenemases. Among these, the KPC-2 carbapenemase represents a significant clinical challenge, being characterized by a broad substrate spectrum that includes aminothiazoleoxime and cephalosporins such as cefotaxime. Moreover, strains harboring KPC-type β-lactamases are often reported as resistant to available β-lactamase inhibitors (clavulanic acid, tazobactam and sulbactam). Therefore, the identification of novel non β-lactam KPC-2 inhibitors is strongly necessary to maintain treatment options. This study explored novel, non-covalent inhibitors active against KPC-2, as putative hit candidates. We performed a structure-based in silico screening of commercially available compounds for non-β-lactam KPC-2 inhibitors. Thirty-two commercially available high-scoring, fragment-like hits were selected for in vitro validation and their activity and mechanism of action vs the target was experimentally evaluated using recombinant KPC-2. N-(3-(1H-tetrazol-5-yl)phenyl)-3-fluorobenzamide (11a), in light of its ligand efficiency (LE = 0.28 kcal/mol/non-hydrogen atom) and chemistry, was selected as hit to be directed to chemical optimization to improve potency vs the enzyme and explore structural requirement for inhibition in KPC-2 binding site. Further, the compounds were evaluated against clinical strains overexpressing KPC-2 and the most promising compound reduced the MIC of the β-lactam antibiotic meropenem by four-fold.

Abstract
We demonstrate wavelength-division-multiplexed (WDM) 200 Gb/s (8 × 25 Gb/s) data transmission over 100 μm long aluminum (Al) surface-plasmon-polariton (SPP) waveguides on a Si3N4 waveguide platform at telecom wavelengths. The Al SPP waveguide was evaluated in terms of signal integrity by performing bit-error-rate (BER) measurements that revealed error-free operation for all eight 25 Gb/s non-return-to-zero (NRZ) modulated data channels with power penalties not exceeding 0.2 dB at 10-9. To the best of our knowledge, this is the first demonstration of WDM enabled data transmission over complementary-metal-oxide-semiconductor (CMOS) SPP waveguides fueling future development of CMOS compatible plasmo-photonic devices for on-chip optical interconnections.

Abstract
Different language skills are considered fundamental for successful reading and spelling acquisition. Extensive evidence has highlighted the central role of phonological awareness in early literacy experiences. However, many orthographic systems also require the contribution of morphological awareness. The goal of this study was to examine the morphological and phonological awareness skills of preschool children as longitudinal predictors of reading and spelling ability by the end of first grade, controlling for the effects of receptive and expressive vocabulary skills. At Time 1 preschool children from kindergartens in the Greek regions of Attika, Crete, Macedonia, and Thessaly were assessed on tasks tapping receptive and expressive vocabulary, phonological awareness (syllable and phoneme), and morphological awareness (inflectional and derivational). Tasks were administered through an Android application for mobile devices (tablets) featuring automatic application of ceiling rules. At Time 2 one year later the same children attending first grade were assessed on measures of word and pseudoword reading, text reading fluency, text reading comprehension, and spelling. Complete data from 104 children are available. Hierarchical linear regression and commonality analyses were conducted for each outcome variable. Reading accuracy for both words and pseudowords was predicted not only by phonological awareness, as expected, but also by morphological awareness, suggesting that understanding the functional role of word parts supports the developing phonology-orthography mappings. However, only phonological awareness predicted text reading fluency at this age. Longitudinal prediction of reading comprehension by both receptive vocabulary and morphological awareness was already evident at this age, as expected. Finally, spelling was predicted by preschool phonological awareness, as expected, as well as by morphological awareness, the contribution of which is expected to increase due to the spelling demands of Greek inflectional and derivational suffixes introduced at later grades.

Abstract
Measuring changes in core body temperature provides a valid method to detect ovulation and increase fertility. 'OvuSense' is a novel vaginal sensor that can predict the fertility window by recording and analysing the changes in intravaginal temperature records. This study aimed to determine patients 'acceptability and satisfaction after using OvuSense'. We approached 13 women to complete a patient satisfaction survey after using OvuSense in a prospective, longitudinal, comparative study, to test its validity and accuracy in detecting ovulation over a minimum period of three cycles. All 13 women agreed to participate in this survey. The majority of the participants found the usage of the reader to be very easy; 76.9% of the women said it was extremely comfortable to use the device during the night and 76.9% found the idea of using the intravaginal reader to be very convenient. Overall, 69.2% of women were extremely satisfied using the device. The idea of detecting intravaginal core body temperature changes appears to be highly acceptable by women.

Abstract
We demonstrate Wavelength Division Multiplexed (WDM)-enabled transmission of 480Gb/s aggregate data traffic (12x40Gb/s) as well as high-quality 1x2 thermo-optic tuning in Dielectric-Loaded Surface Plasmon Polariton Waveguides (DLSPPWs). The WDM transmission characteristics have been verified through BER measurements by exploiting the heterointegration of a 60 μm-long straight DLSPPW on a Silicon-on-Insulator waveguide platform, showing error-free performance for six out of the twelve channels. High-quality thermo-optic tuning has been achieved by utilizing Cycloaliphatic-Acrylate-Polymer as an efficient thermo-optic polymer loading employed in a dual-resonator DLSPPW switching structure, yielding a 9 nm wavelength shift and extinction ratio values higher than 10 dB at both output ports when heated to 90°C.

Abstract
BACKGROUND This study presents the case of a 32-year-old male who is a chronic headache sufferer. He is a professional driver who presented with homonymous hemianopia secondary to a traumatic occipital meningoencephalocele. This is the first time such an association has been reported. CONCLUSIONS The complete lack of previous visual symptoms supports the belief of late development of the hemianopia. However, the chronicity and the nature of the patients' headaches could have justified further investigations in the past.

Abstract
PURPOSE The pancreas is an unusual but occasionally favored site for metastases in patients with advanced malignancy. The pivotal role of computed tomography (CT) and magnetic resonance imaging (MRI) examination in detecting the pancreatic mass and providing guidance to obtain a definitive tissue diagnosis is emphasized in this study. MATERIALS AND METHODS Eleven patients with pancreatic metastases, 4 women and 7 men with a mean age of 62.45 years, were examined in a period of 5 years. All patients underwent CT examination and 3 patients were further evaluated by MRI. RESULTS The primary malignancy was lung carcinoma in 7 patients, breast carcinoma in 3 patients and renal cell carcinoma in 1 patient. The pancreatic metastases were detected during initial staging in 4 cases and during follow-up in 7 cases. The type of metastases was solitary in 7 patients, multiple in 3 patients and diffuse in 1 patient, with rim or homogeneous enhancement. Seven patients had metastases to other organs. CT-guided biopsy was performed in 5 patients. CONCLUSION Disparity in prognosis and management of patients with secondary pancreatic tumors makes detection and characterization of metastases to the pancreas an important goal of CT and MRI evaluation.

Abstract
BACKGROUND Popliteal artery entrapment is an uncommon clinical entity that occurs due to compression of the popliteal artery by adjacent muscle and tendinous structures. Early diagnosis should be established through a combined approach of careful physical examination and history-taking, duplex ultrasonography, and CT angiography. PATIENTS AND METHODS We have studied retrospectively 16 patients of popliteal artery entrapment syndrome, 9 men and 7 women. All patients were scanned with a scanner Picker PQ 5000 after bolus injection of nonionic contrast medium and they all underwent a two-part examination first, with the knee in a neutral position, and, second, with the knee hyperextended. RESULTS At the second phase of the examination 3 patients showed normal findings, 10 patients have shown mild stenosis of the popliteal artery or more severe stenosis due to compression, 2 patients have exhibited bilateral stenosis and 1 patient has also showed popliteal venous compression. CONCLUSION CT angiography images and three-dimensional images are useful not only for depiction of the arterial changes but also identification of the abnormal anatomic structures responsible for the entrapment.

Abstract
Virchow-Robin spaces are enclosed spaces filled with interstitial fluid and covered with pia that accompany arteries, arterioles, veins and venules as they perforate the brain. They are round, linear or punctuate areas depending on the image that parallel cerebrospinal fluid attenuation or signal intensity. They are classically described as isointense to cerebrospinal fluid on images obtained with all pulse sequences. They appear hypointense relative to brain on T1-weighted MR scans and present a high signal intensity on T2-weighted MR scans. They also show complete signal suppression on fluid-attenuated inversion recovery (FLAIR) scans and no enhancement after intravenous contrast administration. However, many pathologic states result in abnormal dilation with an increased number of Virchow-Robin spaces visible on MRI imaging and many pathological conditions cause the spaces to enhance. The purpose of this study is to present the major causes of Virchow-Robin enhancement.

Abstract
The perivascular spaces are normally microscopic. Even in normal brain some Robin-Virchow spaces are usually seen in the area of substantia innominata at the level of anterior commissure. Many pathologic states result in abnormal dilatation with an increased number of spaces visible on MRI imaging. Dilatation is most commonly associated with anterior abnormalities that arise due to aging, diabetes, hypercholesterolemia, smoking, hypertension and other vascular risk factors. The precise etiology of dilatation is currently unknown.

Abstract
Rescue in-vitro fertilisation and embryo transfer (IVF-ET) has been used in high response gonadotrophin intrauterine insemination (IUI) cycles to minimise the risks of ovarian hyperstimulation and multiple gestation. Such unplanned IVF treatment increases the cost of treatment. But can this added cost and the risks associated with IVF be justified? We present our experience with this treatment using clinical pregnancy and live birth rates as the primary outcomes. Between 1998 to 2001, 40 women undergoing IUI cycles who over responded (>3 follicles measuring >15 mm in diameter on the planned day of hCG administration) to gonadotrophin were offered the choice of conversion to IVF-ET or cancel the cycle. 17/40 declined rescue IVF/ET and had their cycles cancelled. 23/40 converted to IVF/ET and underwent transvaginal oocyte retrieval. 21/23 had embryo transferred. The clinical pregnancy and live birth rates were 52% and 48%, respectively. Rescue IVF-ET offers excellent clinical pregnancy and live birth rates in high responders. However, affordability can be an obstacle in the utilization of this treatment option.

Abstract
AIM To examine the biocompatibility of two commercial forms of mineral trioxide aggregate (MTA), by evaluating the morphology of an established cell line. METHODOLOGY The two cements were cast on glass cover slips and cured for 1 or 28 days. Saos-2 osteosarcoma cells were trypsinized and seeded at a density of 1 x 10(5) cells and were then placed in medium over the material-coated coverslips for 1, 5 and 7 days. After these time intervals the media were discarded and the cells fixed. Cell morphological investigation was performed by scanning electron microscopy at various magnifications ranging from x 250 to x 500. The biocompatibility of cement constituents, alusilicate flux and bismuth oxide was also investigated. RESULTS All cement samples cured for 1 day showed a confluent cell monolayer after 5 and 7 days. The response to both materials was similar. Materials cured for 28 days showed incomplete cell confluence after 1 and 5 days. Alusilicate flux and bismuth oxide did not demonstrate biocompatibility. CONCLUSIONS The 1-day cured samples of two commercial forms of MTA showed good biocompatibility. However, the 28-day cured samples were less biocompatible after 1 and 5 days.

Abstract
The aims of this study were to identify the role and sites of action of serine proteinases (SPs) in bone resorption, a process which involves a cascade of events, the central step of which is the removal of bone matrix by osteoclasts (OCs). This resorbing activity, however, is also determined by recruitment of new OCs to future resorption sites and removal of the osteoid layer by osteoblasts (OBs), which enables OCs to gain access to the underlying mineralized bone. The resorption systems we have studied consisted of (i) neonatal calvarial explants, (ii) isolated OCs cultured on ivory slices, (iii) mouse OBs cultured on either radiolabelled type I collagen films or bone-like matrix, (iv) bone marrow cultures to assess OC formation and (v) 17-day-old fetal mouse metatarsal bone rudiments to assess OC migration and fusion. Two separate SP inhibitors, aprotinin and alpha(2)-antiplasmin dose-dependently inhibited (45)Ca release from neonatal calvarial explants: aprotinin (10(-6) M) was the most effective SP inhibitor, producing a maximum inhibitory effect of 55.9%. Neither of the SP inhibitors influenced either OC formation or OC resorptive activity. In contrast, each SP inhibitor dose-dependently inhibited OB-mediated degradation of both type I collagen fibrils and non-mineralized bone matrix. In 17-day-old metatarsal explants aprotinin produced a 55% reduction in the migration of OCs from the periosteum to the mineralized matrix after 3 days in culture but after 6 days in culture aprotinin was without effect on OC migration. Primary mouse osteoblasts expressed mRNA for urokinase type plasminogen activator (uPA), tIssue type plasminogen activator (tPA), the type I receptor for uPA, plasminogen activator inhibitor types I and II and the broad spectrum serine proteinase inhibitor, protease nexin I. In situ hybridization demonstrated expression of tPA and uPA in osteoclasts disaggregated from 6-day-old mouse long bones. We propose that the regulation of these various enzyme systems within bone tIssue determines the sites where bone resorption will be initiated.

Abstract
Oestrogen inhibits bone resorption, at least in part, by regulating the production of several cytokines, including interleukin-6 (IL-6), IL-1, receptor activator of nuclear factor kappaB ligand (RANKL) and osteoprotegerin (OPG) by cells of the osteoblastic lineage. The selective oestrogen receptor modulator raloxifene (RAL) acts on bone in a similar manner to oestrogen, although the mechanisms of action of RAL on osteoblasts still remain unclear. We investigated and compared the effects of 17-beta oestradiol (E(2)) and RAL on the regulation of IL-6, IL-1, RANKL and OPG in vitro in primary human osteoblastic (HOB) cells and in an immortalised clonal human bone marrow stromal cell line (HCC1) with osteoblastic characteristics. We tested E(2) and RAL at concentrations ranging from 10(-12) to 10(-6) M. IL-6, IL-1alpha and IL-1beta, OPG and RANKL were measured by ELISA. RANKL and OPG mRNA steady state level was assessed by quantitative PCR analysis. Both E(2) and RAL led to a significant reduction in IL-6 production in the HOB cells, although the effect was more marked with E(2) (P<0.05). IL-1alpha and IL-1beta also decreased significantly following treatment with E(2) and RAL in the HCC1 cells (E(2) (10(-8), 10(-7) and 10(-6) M), % reduction (means+/-S.E.M.) compared with vehicle-treated cells - IL-1alpha: 84+/-7.4, 70.8+/-2.9*, 78.2+/-4.8*; IL-1beta: 79+/-10, 72.8+/-8.2*, 66.6+/-2.8*; RAL (10(-8), 10(-7) and 10(-6) M) - IL-1alpha: 72.4+/-5*, 79+/- 5.2*, 102+/-7.7; IL-1beta: 67.9+/-3.2*, 69+/-2.5*, 73.8+/- 6.2*; *P<0.05). OPG protein concentration decreased significantly in a dose-dependent manner following treatment with E(2) and RAL (% reduction E(2) (10(-8), 10(-7) and 10(-6) M) - HOB: 72.5+/-8.4*, 80+/-6.7*, 62.8+/-8.9*; HCC1: 109+/-4, 98.8+/-6, 54.5+/-3.4*; RAL (10(-8), 10(-7) and 10(-6) M) - HOB: 81.5+/-5.5*, 62.7+/-7.4*, 55.2+/-10.9*; HCC1: 92.7+/-7.4, 67+/-12.2*, 39+/-4.5*; *P<0.05). In the HCC1 cells, RANKL protein did not change significantly following E(2). In contrast, a significant reduction in RANKL was seen with RAL at 10(-7) and 10(-6) M (66+/-6.4% and 74+/-3% respectively). There was no change in OPG mRNA expression following E(2) or RAL in the HCC1 cells, although in the HOB cells we observed a significant reduction in OPG mRNA. RANKL mRNA decreased significantly in the HCC1 cells following RAL (10(-8), 10(-7)and 10(-6) M) treatment (% change from controls: 52+/-2*, 62+/-1*, 53+/-5.8*; *P<0.05). Similar results were seen in the HOB cells with RAL at 10(-6) M (RANKL mRNA: 72+/-5.5, P<0.05). In addition, there was a significant decrease in the RANKL/OPG ratio after RAL at 10(-6) M (HOB: 65.6+/-5*, HCC1: 56.9+/-20*; *P<0.05). RANKL/OPG ratio did not change significantly in the HCC1 cells following E(2). However, in contrast to RAL, we observed an increase in the RANKL/OPG ratio in the HOB cells following treatment with E(2). In conclusion, the study shows that RAL and E(2) have divergent cell-specific effects on the regulation of cytokines. The data also suggest that, in contrast to E(2), RAL may exert its anti-resorptive actions, at least in part, via the RANKL/OPG pathway. Further in vivo studies are required to confirm this.

Abstract
BACKGROUND Absence of the adnexa may be congenital or acquired. However, the etiology is often uncertain. CASE A 27-year-old woman presented with a 3-year history of subfertility. Her irregular menstruation was associated with acne vulgaris, alopecia, and elevated body mass index. Transvaginal ultrasonography of the pelvis showed a normal uterus, a normal right ovary, but a polycystic-appearing left ovary. A hysterosalpingogram demonstrated a normal uterine cavity, prompt filling and spilling of contrast material from the left fallopian tube, but no filling on the right. Subsequent laparoscopy showed an unexpected absence of right adnexa and presence of a solitary rounded free-floating mass enshrouded in the omentum. She did not have a history of abdominal pain or surgery. CONCLUSION The evidence suggests that the patient might have had an asymptomatic infarction of the right adnexa.

Abstract
Biocompatibility of two variants of accelerated Portland cement (APC) were investigated in vitro by observing the cytomorphology of SaOS-2 osteosarcoma cells in the presence of test materials and the effect of these materials on the expression of markers of bone remodelling. Glass ionomer cement (GIC), mineral trioxide aggregate (MTA) and unmodified Portland cement (RC) were used for comparison. A direct contact assay was undertaken in four samples of each test material, collected at 12, 24, 48 and 72 h. Cell morphology was observed using scanning electron microscopy (SEM) and scored. Culture media were collected for cytokine quantification using enzyme-linked immunosorbent assay (ELISA). On SEM evaluation, healthy SaOS-2 cells were found adhering onto the surfaces of APC variant, RC and MTA. In contrast, rounded and dying cells were observed on GIC. Using ELISA, levels of interleukin (IL)-1beta, IL-6, IL-18 and OC were significantly higher in APC variants compared with controls and GIC (p<0.01), but these levels of cytokines were not statistically significant compared with MTA. The results of this study provide evidence that both APC variants are non-toxic and may have potential to promote bone healing. Further development of APC is indicated to produce a viable dental restorative material and possibly a material for orthopaedic

Abstract
BACKGROUND The irradiation of the ovaries of reproductive age women during fluoroscopically guided selective salpingography and tubal catheterization has raised concern about the safety of the procedure. In addition to the risk of cancer induction, which exists with the irradiation of all tissues, with the gonads, the induction of hereditary disorders is possible. The objective of this study was to estimate these risks and present them in a clinically meaningful way. METHODS Retrospective analysis was undertaken of 366 consecutive cases of selective salpingography and tubal catheterization performed at the Birmingham Women's Hospital, UK. The radiation doses of different types of procedure were compared with the background annual radiation dose. The risks of cancer and genetic disorders induction were calculated using conversion coefficients published by the International Commission on Radiological Protection. RESULTS The radiation dose women were exposed to during selective salpingography and tubal catheterization under fluoroscopic guidance was a fraction of the background annual radiation dose. The excess lifetime risks of cancer and hereditary disorders were in the order of four to 13 and two to six per million procedures respectively. CONCLUSIONS The long term risks of selective salpingography and tubal catheterization under fluoroscopic guidance are low.

Abstract
X-rays have an antiangiogenic effect in the chicken embryo chorioallantoic membrane (CAM) model of in vivo angiogenesis. Our study demonstrates that X-rays induce an early apoptosis of CAM cells, modulate the synthesis and deposition of extracellular matrix (ECM) proteins involved in regulating angiogenesis and affect angiogenesis induced by tumour cells implanted onto the CAM. Apoptosis was evident within 1-2 hr, but not later than 6 hr after irradiation. Fibronectin, laminin, collagen type I, integrin alpha(v)beta3 and MMP-2 protein amounts were all decreased 6 hr after irradiation. In contrast, collagen type IV, which is restricted to basement membrane, was not affected by irradiation of the CAM. There was a similar decrease of gene expression for fibronectin, laminin, collagen type I and MMP-2, 6 hr after irradiation. The levels of mRNA for integrin alpha(v)beta3 and collagen type IV were unaffected up to 24 hr after irradiation. The decrease in both protein and mRNA levels was reversed at later time points and 48 hr after irradiation, there was a significant increase in the expression of all the genes studied. When C6 glioma tumour cells were implanted on irradiated CAMs, there was a significant increase in the angiogenesis induced by tumour cells, compared to that in non-irradiated CAMs. Therefore, although X-rays have an initial inhibitory effect on angiogenesis, their action on the ECM enhances new vessel formation induced by glioma cells implanted on the tissue.

Abstract
There is now considerable discussion whether intracytoplasmic sperm injection (ICSI) should be used in all cases of IVF. A critical and balanced view of the current literature is presented. The difficult question is how to identify men with apparently normal semen who are likely to fail to achieve a pregnancy using IVF. In conclusion, from both the safety and scientific viewpoint, ICSI should only be used in cases where success at IVF is regarded as unlikely.

Abstract
OBJECTIVE To determine the effectiveness of aspirin to prevent preeclampsia in women identified as high risk for preeclampsia by an abnormal second-trimester uterine artery Doppler examination. DATA SOURCES Searches were conducted in MEDLINE, Embase, the Cochrane Controlled Trials Register, and Science Citation Index for randomized trials published from 1966 to 2000, using the following medical subject headings and key words: "aspirin," "antiplatelet*," "salicyl*," "acetylsalicyl*," "platelet aggregation inhibitors," "ultrasonography," "ultraso*," and "Doppler." STUDY SELECTION We included all randomized trials that evaluated the effectiveness of aspirin compared with placebo or no treatment in women with an abnormal uterine artery Doppler and that reported clinically relevant perinatal and maternal outcomes. Study selection, quality assessment, and data extraction were performed in duplicate. TABULATION, INTEGRATION, AND RESULTS There were five relevant trials. Pooling of results from these trials showed a significant benefit of aspirin in reducing preeclampsia (odds ratio [OR] 0.55, 95% confidence interval [CI] 0.32, 0.95). The baseline risk of preeclampsia in women with abnormal uterine artery Doppler was 16%, and the number of women needed to be treated with aspirin to prevent one case of preeclampsia was 16 (95% CI 8, 316). Women on aspirin had babies who were on average 82 g heavier than controls, but this result did not reach statistical significance (weighted mean difference 81.5, 95% CI 40.27, 203.27). CONCLUSION Uterine artery Doppler assessment identifies high-risk women in whom aspirin therapy results in a significant reduction in preeclampsia.

Abstract
A core activity of evidence-based practice is the search for and appraisal of evidence on specific clinical issues. Clinicians vary in their competence in this process; we therefore developed a 16-item checklist for quality of content (relevance and validity) and presentation (useability, attribution, currency and contact details). This was applied to a set of 55 consecutive appraisals conducted by clinicians and posted at a web-based medical journal club site. Questions were well formulated in 51/55 (92%) of the appraisals. However, 22% of appraisals missed the most relevant articles to answer the clinical question. Validity of articles was well appraised, with methodological information and data accurately extracted in 84% and accurate conversion to clinically meaningful summary statistics in 87%. The appraisals were presented in a useable way with appropriate and clear bottom-lines stated in 95%. The weakest link in production of good-quality critical appraisals was identification of relevant articles. This should be a focus for evidence-based medicine and critical appraisal skills.
