Abstract
We report the first measurement of low-energy proton-capture cross sections of ^{124}Xe in a heavy-ion storage ring. ^{124}Xe^{54+} ions of five different beam energies between 5.5 and 8 AMeV were stored to collide with a windowless hydrogen target. The ^{125}Cs reaction products were directly detected. The interaction energies are located on the high energy tail of the Gamow window for hot, explosive scenarios such as supernovae and x-ray binaries. The results serve as an important test of predicted astrophysical reaction rates in this mass range. Good agreement in the prediction of the astrophysically important proton width at low energy is found, with only a 30% difference between measurement and theory. Larger deviations are found above the neutron emission threshold, where also neutron and γ widths significantly impact the cross sections. The newly established experimental method is a very powerful tool to investigate nuclear reactions on rare ion beams at low center-of-mass energies.

Abstract
SummaryPrevious studies investigating continuous unfractionated heparin (UFH) therapy report age-related differences in UFH response in children, as measured by APTT and anti-Xa assay. This study determined the age-related response following administration of a single UFH bolus of 75–100 IU/kg in children. Venous blood samples were collected from children (n=56) at 15, 30, 45 and 120 minutes post-UFH. Anti-Xa, anti-IIa, APTT, TCT and protamine titration were performed on all samples. Age-dependent differences in the effect and concentration of UFH were identified for the anti-Xa, anti-IIa and protamine titration as-says, respectively. In addition, a trend suggesting a proportional increase in anti-Xa and anti-IIa-mediated UFH effect with age was evident. Logistic regression demonstrated an increase in protamine titration of 0.6 IU/ml for every year of age in samples collected 15 minutes post-UFH. UFH-mediated anti-IIa activity was reduced compared to anti-Xa activity across childhood, with a two-fold increase in anti-Xa to anti-IIa ratio in infants less than one year of age compared to teenagers in the setting of high UFH concentrations. This study demonstrates that the previously reported age-dependent response to UFH occurs in the context of an age-dependent serum concentration of UFH. The trend toward increased UFH serum concentration and anticoagulant activity with age may be related to short-term differences in UFH binding to coagulant and competitive plasma proteins in vivo.

Abstract
Large cell neuroendocrine cervical carcinoma (LCNEC) is a rare and aggressive cancer that tends to spread and recur early despite intensive multimodal treatment. Conventional treatment strategies for early stage neuroendocrine tumour (NET) include radical hysterectomy followed by adjuvant chemotherapy. There are only 2 reported cases of fertility sparing treatment for NET. We report on the first case of successful conception and delivery at term following radical trachelectomy for early stage LCNEC. First reported case of delivery at term following radical trachelectomy for LCNEC 3 year recurrence free survival following radical trachelectomy in LCNEC Continue data collection on both oncologic and fertility outcomes in LCNEC

Abstract
BACKGROUND Ovarian cancer is seventh most common cancer in women worldwide. Approximately 1.3% of women will be diagnosed with ovarian cancer at some point during their life time. The majority of tumours arise from surface of the ovary (epithelial). Two thirds of these women will present with advanced disease, requiring aggressive treatment, which includes debulking surgery (removal of as much disease as possible) and chemotherapy. However, most women (75%) with advanced epithelial ovarian cancer (EOC) will relapse following surgery and chemotherapy. Patients who relapse are treated with either platinum or non-platinum drugs and this is dependent on the platinum-sensitivity and platinum-free interval. These drug regimens are generally well-tolerated although there are potential severe side effects. New treatments that can be used to treat recurrence or prevent disease progression after first-line or subsequent chemotherapy are important, especially those with a low toxicity profile. Hormones such as luteinising hormone releasing hormone (LHRH) agonists have been used in the treatment of relapsed EOC. Some studies have shown objective remissions, while other studies have shown little or no benefit. Most small studies report a better side-effect profile for LHRH agonists when compared to standard chemotherapeutic agents used in EOC. OBJECTIVES To compare the effectiveness and safety of luteinising hormone releasing hormone (LHRH) agonists with chemotherapeutic agents or placebo in relapsed epithelial ovarian cancer (EOC). SEARCH METHODS We searched the Cochrane Gynaecological Cancer Group trials register, Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE and Embase up to January 2016. We also searched registers of clinical trials and abstracts of scientific meetings. SELECTION CRITERIA Randomised controlled trials (RCTs) that compared LHRH agonists with chemotherapeutic agents or placebo in relapsed EOC. DATA COLLECTION AND ANALYSIS Two review authors independently assessed whether relevant studies met the inclusion criteria, retrieved data and assessed risk of bias. MAIN RESULTS Two studies, including 97 women, met our inclusion criteria: one assessed LHRH agonist (leuprorelin) use in relapsed (platinum-resistant and platinum-refractory) EOC in comparison with a chemotherapeutic agent (treosulfan) (Du Bois 2002); the other examined LHRH agonist (decapeptyl) versus a placebo (Currie 1994). Since both studies had different control groups, a meta-analysis was not possible.There may be little or no difference between treatment with leuprorelin or treosulfan in overall survival (OS) (hazard ratio (HR) 0.98, 95% confidence interval (CI) 0.58 to 1.67; very low-quality evidence) or progression-free survival (PFS) at six and 12 months (risk ratio (RR) 0.61, 95% CI 0.22 to 1.68, and RR 0.65, 95% CI 0.12 to 3.66; very low-quality evidence), respectively (Du Bois 2002). The duration of follow-up was 2.5 years and quality of life (QoL) was not reported in this study.Alopecia and fatigue were probably more common with treosulfan than leuprorelin (alopecia RR 0.32, 95% CI 0.12 to 0.91 (very low-quality evidence)). There may be little or no difference in other Grade 3/4 side effects: nausea and vomiting (RR 0.65, 95% CI 0.12 to 3.66 (very low-quality evidence)); neurotoxicity (RR 0.32, 95% CI 0.01 to 7.71 (very low-quality evidence)) and neutropenia (RR 0.97, 95% 0.06 to 14.97 (very low-quality evidence)),The Currie 1994 study, which compared decapeptyl treatment with placebo, reported mean PFS of 16 weeks verus 11.2 weeks, respectively. No relative effects measures or P value at a particular time point were reported. Overall survival (OS) and QoL outcomes were not reported. In addition, adverse events were only mentioned for the decapeptyl group.Adverse events were incompletely reported (no adverse events in decapeptyl group, but not reported for the placebo group). AUTHORS' CONCLUSIONS Based on this review of two small RCTs, there is not enough evidence to comment on the safety and effectiveness of LHRH agonists in the treatment of platinum-refractory and platinum-resistant (relapsed) EOC. Overall, the quality of evidence for all outcomes (including OS, PFS, QoL and adverse events) is very low.

Abstract
BACKGROUND Tuberculous lymphadenitis is the commonest form of extrapulmonary tuberculosis. However, the optimal approach to diagnosis, employing biopsy by either fine needle aspiration (FNA) or surgical excision, remains uncertain. AIMS To evaluate the diagnostic value of biopsy using each of the component diagnostic modalities of FNA (microscopy, cytology and culture), and compare these with excision biopsy in the diagnosis of tuberculous lymphadenitis in a predominantly migrant population in Melbourne. METHODS A retrospective examination of tuberculous lymphadenitis cases presenting to Western Health over 12 years was conducted. Using a reference method of positive culture of Mycobacterium tuberculosis, the diagnostic sensitivities of each modality employed in FNA were determined. RESULTS Forty-two subjects having FNA and 30 having excision biopsy as the initial investigation were compared. Among specimens obtained by FNA, sensitivity of microscopy was 18% (95% confidence interval (CI): 5–40%) and sensitivity of cytology was 38% (95% CI: 20–59%). For specimens obtained by excision biopsies, sensitivities for microscopy and histology were 17% (95% CI: 2–32%) and 96% (95% CI: 88–100%) respectively. Sensitivity of culture performed on FNA specimens was 86% (95% CI: 65–97%). CONCLUSIONS Given the relatively high sensitivity of mycobacterial cultures from FNA, this study supports its routine use as the initial investigation in most patients with suspected tuberculous lymphadenitis. Microscopy and cytology add relatively little to the clinical utility of FNA

Abstract
Increased care provision and clinical activity in General Practice in Ireland will have important manpower implications. Recent developments in medical education policy including the introduction of graduate-entry medical degree programmes may help address this issue. The aim of this study was to determine GP career intentions among students on an Irish graduate-entry medical degree programme and to identify factors that influence these. An electronic cross-sectional study of students at University of Limerick Graduate-Entry Medical School (UL-GEMS) was undertaken. We received 139 replies (78% response rate). 41 (29%) reported GP was their current preferred career choice, while 29 (19%) reported it was their preferred career choice on entry to medical school. This first study to present data on GP career intentions among graduate-entry students in Ireland highlights the specialty as a popular preferred career choice among students, both on entry to, and during medical school. The study also identifies factors which are likely to be important in determining career intentions. Further research to examine this issue at other graduate-entry medical schools in Ireland and to determine whether our findings are pursued over time amongst graduates is a priority.

Abstract
The main water-soluble carbohydrates in temperate forage grasses are polymeric fructans. Fructans consist of fructose chains of various chain lengths attached to sucrose as a core molecule. In grasses, fructans are a complex mixture of a large number of isomeric oligomers with a degree of polymerisation ranging from 3 to >100. Accurate monitoring and unambiguous peak identification requires chromatographic separation coupled to mass spectrometry. The mass range of ion trap mass spectrometers is limited, and we show here how monitoring selected multiply charged ions can be used for the detection and quantification of individual isomers and oligomers of high mass, particularly those of high degree of polymerization (DP > 20) in complex plant extracts. Previously reported methods using linear ion traps with low mass resolution have been shown to be useful for the detection of fructans with a DP up to 49. Here, we report a method using high-resolution mass spectrometry (MS) using an Exactive Orbitrap MS which greatly improves the signal-to-noise ratio and allows the detection of fructans up to DP = 100. High-sugar (HS) Lolium perenne cultivars with high concentrations of these fructans have been shown to be of benefit to the pastoral agricultural industry because they improve rumen nitrogen use efficiency and reduce nitrous oxide emissions from pastures. We demonstrate with our method that these HS grasses not only contain increased amounts of fructans in leaf blades but also accumulate fructans with much higher DP compared to cultivars with normal sugar levels.

Abstract
The identification of quantitative trait loci (QTL) for plant metabolites requires the quantitation of these metabolites across a large range of progeny. We developed a rapid metabolic profiling method using both untargeted and targeted direct infusion tandem mass spectrometry (DIMSMS) with a linear ion trap mass spectrometer yielding sufficient precision and accuracy for the quantification of a large number of metabolites in a high-throughput environment. The untargeted DIMSMS method uses top-down data-dependent fragmentation yielding MS(2) and MS(3) spectra. We have developed software tools to assess the structural homogeneity of the MS(2) and MS(3) spectra hence their utility for phenotyping and genetical metabolomics. In addition we used a targeted DIMS(MS) method for rapid quantitation of specific compounds. This method was compared with targeted LC/MS/MS methods for these compounds. The DIMSMS methods showed sufficient precision and accuracy for QTL discovery. We phenotyped 200 individual Lolium perenne genotypes from a mapping population harvested in two consecutive years. Computational and statistical analyses identified 246 nominal m/z bins with sufficient precision and homogeneity for QTL discovery. Comparison of the data for specific metabolites obtained by DIMSMS with the results from targeted LC/MS/MS analysis showed that quantitation by this metabolic profiling method is reasonably accurate. Of the top 100 MS(1) bins, 22 ions gave one or more reproducible QTL across the 2 years.

Abstract
INTRODUCTION Anti-Factor Xa (Anti-Xa) assays specifically determine the anticoagulant activity of UFH by measuring the ability of heparin-bound Antithrombin (AT) to inhibit a single enzyme, Factor Xa (FXa). Recent improvements in the automation, cost-effectiveness and accessibility of the assay to clinicians, have resulted in the Anti-Xa assay becoming a part of daily clinical practice in many institutions. OBJECTIVES We hypothesized that different Anti-Xa assays have different applicability for use in clinical settings, depending on the amount of UFH administered. This was investigated in a tertiary paediatric institution. MATERIALS AND METHODS Samples were collected from children receiving Low-dose of UFH of at least 10 IU/kg/h, with or without a previous bolus of up to 25 IU/kg/h, within the previous 6 h in the PICU and HDU. High-dose UFH population consisted of children undergoing Cardiac Catheterization (CC), who received a bolus of UFH of 100 IU/kg body weight, 30 min prior to sampling. RESULTS AND CONCLUSIONS The Anti-Xa activity for a given dose of UFH was found to vary significantly based on the Anti-Xa assay and the population being monitored. Our study suggests that the MODIFIED COMATIC Anti-Xa assay provides the best physiological measure of the UFH effect in children, as it does not introduce sources of error, such as exogenous AT, which may increase the measured ant Factor Xa activity, nor Dextran Sulphate which can displace plasma protein bound heparin and once again leading to falsely elevated assay results. Further studies that include assessment of clinical outcomes are required to confirm the applicability of use of this particular assay in monitoring UFH therapy.

Abstract
OBJECTIVES To evaluate the use of image-guided biopsy (IGB) in routine clinical practice to obtain site-specific diagnoses in women presenting with peritoneal carcinomatosis (PC). STUDY DESIGN Retrospective case study. SETTING Tertiary referral centre. POPULATION A total of 149 consecutive women with PC who underwent IGB. METHODS Biopsy was performed in women considered unsuitable for primary surgery because of poor performance status or disease unlikely to be optimally debulked, with a prior history of malignancy or where there was clinicoradiological uncertainty about primary tumour site. Standard haematoxylin-eosin histological analysis was supplemented with immunohistochemistry. MAIN OUTCOME MEASURES The rate of site-specific diagnosis. RESULTS A total of 149 women underwent IGB using computed tomography or ultrasound over a 6-year period. The only complication was one rectus sheath haematoma. In 138 (93%) women, a site-specific cancer diagnosis was made on the IGB (including 111 müllerian tract, 8 gastrointestinal tract, 4 breast and 3 lymphoma); in ten women, a repeat biopsy was necessary, giving an overall failure rate of 7%. In a further six women, malignancy was confirmed but a site-specific diagnosis could not be made, and in four women, biopsy showed benign tissue. A site-specific diagnosis was obtained in 29 of the 32 women (94%) with previous malignancy, of which 18/32 (56%) showed a new primary cancer. CONCLUSIONS IGB is a safe and accurate technique for providing site-specific diagnoses in women with PC in routine clinical practice, including those with a previous relevant malignancy. IGB can replace laparoscopic or open biopsy in defining primary therapeutic options. The data would suggest that the biopsy should be performed with ultrasound where feasible.

Abstract
When women with a history of breast cancer present with peritoneal carcinomatosis, the differential diagnosis lies between recurrent breast cancer or a new primary tumor. This scenario is of particular relevance to women with a BRCA gene mutation, who have a genetic predisposition to develop second primary tumors of the ovary, fallopian tube, and peritoneum. We describe the use of image-guided core biopsy as an alternative to laparoscopy or exploratory laparotomy in providing minimally invasive diagnosis in this increasingly common clinical dilemma.

Abstract
BACKGROUND Patients with an acute myocardial infarction require a rapid response to their symptoms and the earlier fibrinolysis is given (where indicated), the better the outcome. AIMS The aim of this study is to compare 'door to needle times' for fibrinolysis in Acute Myocardial Infarction (AMI) in three phases of one year each, at Letterkenny General Hospital. METHODS In the PREINTERVENTION year all fibrinolysis was performed in the Coronary Care Unit (CCU). In the INTERVENTION year Emergency Department (ED) fast track fibrinolysis was introduced and in the POST INTERVENTION year most fibrinolysis was performed on fast track in the ED. RESULTS The time saved by the introduction of ED fibrinolysis was significant, 41 minutes on average per patient. Elderly, female patients were more likely to bypass ED fast track fibrinolysis and to be brought to CCU for fibrinolysis, with attendant delays. This has educational implications in relation to the variation in clinical presentation of AMI with age and sex. CONCLUSION The ED fast track fibrinolysis system is recommended as an effective, safe, achievable and worthwhile intervention towards improving 'door to needle times' for fibrinolysis in AMI.

Abstract
PURPOSE Germline mutations in the BRCA1 and BRCA2 genes confer increased susceptibility to ovarian cancer. There is evidence that tumors in carriers may exhibit a distinct distribution of pathological features, but previous studies on the pathology of such tumors have been small. Our aim was to evaluate the morphologies and immunophenotypes in a large cohort of patients with familial ovarian cancer. EXPERIMENTAL DESIGN We performed a systematic review of ovarian tumors from 178 BRCA1 mutation carriers, 29 BRCA2 mutation carriers, and 235 controls with a similar age distribution. Tumors were evaluated by four pathologists blinded to mutation status. Both morphological features and immunochemical staining for p53 and HER2 were evaluated. RESULTS Tumors in BRCA1 mutation carriers were more likely than tumors in age-matched controls to be invasive serous adenocarcinomas (odds ratio, 1.84; 95% confidence interval, 1.21-2.79) and unlikely to be borderline or mucinous tumors. Tumors in BRCA1 carriers were of higher grade (P < 0.0001), had a higher percentage solid component (P = 0.001), and were more likely to stain strongly for p53 (P = 0.018). The distribution of pathological features in BRCA2 carriers was similar to that in BRCA1 carriers. CONCLUSIONS Use of pathological features can substantially improve the targeting of predictive genetic testing. Results also suggest that BRCA1 and BRCA2 tumors are relatively aggressive and may be expected to have poor prognosis, although this may be treatment dependent.

Abstract
Nine transitions of dipole character have been identified linking an excited superdeformed (SD) band in 152Dy to the yrast SD band. As a result, the excitation energy of the lowest level in the excited SD band has been measured to be 14 238 keV. This corresponds to a 1.3 MeV excitation above the SD ground state. The levels in this band have tentatively been determined to be of negative parity and odd spin. The measured properties are consistent with an interpretation in terms of a rotational band built on a collective octupole vibration.

Abstract
The excitation energy, spin, and parity of the yrast superdeformed band in 152Dy have been firmly established. The evidence comes mainly from the measured properties of a 4011 keV single-step transition connecting the yrast superdeformed level fed by the 693 keV transition to the 27- yrast state. Four additional, weaker, linking gamma rays have been placed as well. The excitation energy of the lowest superdeformed band member is 10 644 keV and its spin and parity are determined to be 24+.

Abstract
PURPOSE To assess image-guided peritoneal core biopsy for the diagnosis of tumor type and treatment of patients with peritoneal carcinomatosis. MATERIALS AND METHODS Thirty-five women (age range, 47-85 years; mean age, 69 years) prospectively identified in a gynecologic oncology center underwent 18-gauge core biopsy in omental cake (n = 25), peritoneal (n = 7), or adnexal (n = 3) sites. No complications of biopsy occurred. Standard hematoxylin-eosin analysis of the biopsy cores was supplemented by immunohistochemical markers to CA-125, carcinoembryonic antigen, cytokeratin 7, and cytokeratin 20. Diagnoses were validated with further multidisciplinary review, subsequent surgery, and response to specific chemotherapy. RESULTS In 27 (77%) of the 35 women, a confident primary site diagnosis was obtained with standard hematoxylin-eosin analysis of core biopsy material from the following sites: ovary (n = 22), breast (n = 2), colon (n = 2), and lymphoma (n = 1). The finding at hematoxylin-eosin analysis in another seven (20%) women was poorly differentiated adenocarcinoma with no definite primary site but with an immunohistochemical profile suggesting ovarian cancer (CA-125 positive, carcinoembryonic antigen negative, cytokeratin 7 positive, cytokeratin 20 negative). There was one false-negative biopsy result. CONCLUSION Image-guided peritoneal core biopsy with hematoxylin-eosin analysis supplemented with immunohistochemical analysis is a simple, safe, and accurate technique for providing site-specific diagnoses in women with undiagnosed peritoneal carcinomatosis.

Abstract
PURPOSE We created viable bladder tissue by transplantation with immunosuppression. MATERIALS AND METHODS For bladder transplantation the bladder of newborn Brown-Norway rats was excised and each was transplanted into a pouch created in the distal omentum of a 5-week-old Lewis rat. In 15 group 1 rats no immunosuppressive agent was used. In 20 group 2 rats 0.6 mg./kg. FK-506 daily were given intramuscularly until a predetermined day of harvest. Recipient rats were sacrificed on day 3, 5, 7 or 14 after bladder transplantation, and the bladder grafts were harvested and formalin fixed. Hematoxylin and eosin staining was done to examine bladder graft survival and the degree of rejection, and immunohistochemical testing was performed for assessing the vesical nervous system. In 5 rats in the control group bladder augmentation was performed by anastomosing the bladder graft to the native bladder. Each augmented bladder was harvested 21 days later for histopathological assessment. RESULTS Overall bladder graft survival was 96.4%. Each successfully transplanted bladder graft appeared macroscopically as a thin walled cyst. In group 1 all bladder grafts showed rejection with cellular infiltration. In group 2 there was mild rejection in 5 rats and no evidence of rejection in the remaining 15. All group 2 bladder grafts had intact nerve distribution. Bladder augmentation was successful in all 5 cases and the mucosa was normal throughout each augmented bladder. CONCLUSION Because FK-506 successfully prevents rejection, our technique would appear to have the potential for creating viable bladder tissue that may be used for bladder augmentation in cases of vesical exstrophy or neurogenic bladder.

Abstract
BACKGROUND The effect of cholesterol-lowering therapy on death from coronary heart disease in older patients with previous coronary heart disease and average cholesterol levels is uncertain. OBJECTIVE To compare the relative and absolute effects of pravastatin on cardiovascular disease outcomes in patients with coronary heart disease who are 65 years of age or older with those in patients 31 to 64 years of age. DESIGN Subgroup analysis of a randomized, placebo-controlled trial. SETTING 87 centers in Australia and New Zealand. PATIENTS 3514 patients 65 to 75 years of age, chosen from among 9014 patients with previous myocardial infarction or unstable angina and a baseline plasma cholesterol level of 4.0 to 7.0 mmol/L (155 to 271 mg/dL). INTERVENTION Pravastatin, 40 mg/d, or placebo. MEASUREMENTS Major cardiovascular disease events over 6 years. RESULTS Older patients were at greater risk than younger patients (31 to 64 years of age) for death (20.6% vs. 9.8%), myocardial infarction (11.4% vs. 9.5%), unstable angina (26.7% vs. 23.2%), and stroke (6.7% vs. 3.1%) (all P < 0.001). Pravastatin reduced the risk for all cardiovascular disease events, and similar relative effects were observed in older and younger patients. In patients 65 to 75 years of age, pravastatin therapy reduced mortality by 21% (CI, 7% to 32%), death from coronary heart disease by 24% (CI, 7% to 38%), coronary heart disease death or nonfatal myocardial infarction by 22% (CI, 9% to 34%), myocardial infarction by 26% (CI, 9% to 40%), and stroke by 12% (CI, -15% to 32%). For every 1000 older patients treated over 6 years, pravastatin prevented 45 deaths, 33 myocardial infarctions, 32 unstable angina events, 34 coronary revascularization procedures, 13 strokes, or 133 major cardiovascular events, compared with 22 deaths and 107 major cardiovascular events per 1000 younger patients. Among older patients, the numbers needed to treat were 22 (CI, 17 to 36) to prevent one death from any cause, 35 (CI, 24 to 67) to prevent one death from coronary heart disease, and 21 (CI, 17 to 31) to prevent one coronary heart disease death or nonfatal myocardial infarction. CONCLUSIONS In older patients with coronary heart disease and average or moderately elevated cholesterol levels, pravastatin therapy reduced the risk for all major cardiovascular events and all-cause mortality. Since older patients are at greater risk than younger patients for these events, the absolute benefit of treatment is significantly greater in older patients.

Abstract
Clinically, a venous aneurysm is seen as a nonpulsatile mass with shrinkage upon elevation and enlargement with dependency. Confirmation of the diagnosis is best made by venography. In the case presented here of a rare aneurysm of the dorsal venous arch, the diagnosis of venous aneurysm was based on the histopathologic and intraoperative findings. If a venous aneurysm is symptomatic, it should be excised, with ligation of all feeder veins. In all cases, accurate preoperative diagnosis and evaluation allows for appropriate surgical planning.

Abstract
BACKGROUND The LIPID study is a major trial of secondary prevention of coronary-heart-disease events that includes hospital admission with unstable angina (as well as myocardial infarction) as a qualifying event. In this substudy of LIPID, we compared subsequent cardiovascular risks and the effects of pravastatin in patients with previous unstable angina or previous myocardial infarction. METHODS 3260 patients diagnosed with unstable angina and 5754 with acute myocardial infarction 3-36 months previously were randomly assigned 40 mg pravastatin daily or placebo over a mean of 6.0 years. The risk reduction of a range of cardiovascular events was estimated by means of the hazard ratio in Cox's proportional hazards model. FINDINGS Among patients assigned placebo, survival in the two diagnosis groups was similar. The relative risk reduction for mortality with pravastatin was 20.6% in the myocardial infarction group and 26.3% in the unstable angina group (p=0.55). Pravastatin significantly reduced the rates of all prespecified coronary endpoints in the myocardial infarction group. In patients with previous unstable angina, coronary heart disease mortality, total mortality, myocardial infarction, a need for coronary revascularisation, the number of admissions to hospital, and the number of days in hospital were significantly lower with pravastatin. Overall, hospital admission for unstable angina was the most common endpoint (24.6% of the placebo group; 22.3% of the pravastatin group). INTERPRETATION Patients who have survived acute myocardial infarction or unstable angina have a similar long-term prognosis, a high occurrence of subsequent unstable angina, and benefit similarly from therapy with pravastatin.

Abstract
OBJECTIVE To assess the role of neural networks in predicting the likelihood of malignancy in women presenting with ovarian tumours. DESIGN Retrospective case study. SETTING University Department of Obstetrics and Gynaecology, St James's Hospital, Leeds. METHODS Information from 217 cases with histologically proven benign, borderline or malignant tumours was extracted for study. Four variables (age, ultrasound findings with and without colour Doppler imaging and CA125) were entered in the neural network classifier. The neural network results were compared with logistic regression analysis. RESULTS When used in the neural network the variables of age, CA125 and ultrasound score produced the best result with a sensitivity of 95% and a corresponding specificity of 78% in predicting malignancy. Logistic regression gave a sensitivity or 82% for a specificity of 51%. CONCLUSION The neural network is a good method of combining diagnostic variables and may be a useful predictor of malignancy in women presenting with ovarian tumours. A comparison of the performance of the neural network with conventional diagnostic methods would be warranted prior to use in clinical practice.

Abstract
Although incisional metastases following surgery for cervical cancer are extremely rare, port-site disease following minimal-access surgery is becoming increasingly reported. We report a case of a metastasis which occurred at a port site following laparoscopic removal of lymph nodes affected by cervical adenosquamous carcinoma. This report adds to the literature suggesting that cutaneous tumor deposition may be enhanced by this method of surgery.

Abstract
DESIGN A retrospective review of women undergoing computed tomography (CT) as part of the investigation and management of pathologically proven ovarian cancer in a single specialist gynaecological cancer centre. OBJECTIVE To ascertain CT appearances and prognostic significance of splenic involvement in ovarian cancer. RESULTS We found a 10.3% frequency of splenic metastasis in a series of 321 patients with ovarian cancer. Thirty-three women had splenic metastases demonstrated on CT. Twenty-three women had surface lesions with an irregular scalloped shape and broad contact with the splenic surface; 17 of these women had lesions at presentation. Ten women had parenchymal lesions, five at presentation and five at relapse, typically with a rounded shape surrounded by normal splenic tissue. Four out of 10 cases with parenchymal involvement showed lesion progression during chemotherapy. However, lesion progression occurred in only one of 23 cases with surface disease (P < 0.025, Fisher's exact test). In 16 cases with disease involving both spleen and liver, the response to chemotherapy was the same in both organs. CONCLUSION We have found a higher frequency of splenic metastasis from ovarian cancer during life than previously reported. Parenchymal lesions are significantly less likely to respond to treatment than surface lesions but are more commonly a feature of relapsed disease. We have demonstrated that splenic metastases behave similarly to liver metastases in ovarian cancer. We suggest that the presence of splenic parenchymal metastasis is indicative of FIGO stage IV disease. This finding has implications for proposed cytoreductive surgery.

Abstract
Cutaneous melanomas rarely metastasize to the ovary; however, we have recently encountered three cases which have proved a diagnostic dilemma. All presented with a pelvic mass and a past history of cutaneous melanoma but both ultrasound examination and CT scanning proved inconclusive and neither was able to accurately characterize the lesions. Magnetic resonance imaging (MRI) was able to demonstrate the presence of melanin in one of the ovarian lesions as peripheral high signal change on T1-weighted images. The two lesions without melanin failed to show this feature. MRI may therefore be useful in the diagnosis of ovarian melanoma but only if melanin is present.

Abstract
Of the 187 cases of infantile choledochal cyst treated at our hospitals, we encountered 13 with spontaneous perforation. All cases were under 4 years old. Eight cases were found to have biliary peritonitis and 5 had a sealed perforation. The shape of the extrahepatic bile duct was cystic in 8 and fusiform in 5. The cyst wall around the perforation was filmy and bile was found to be oozing through the thinned wall. Nine perforations were single while 4 cases had multiple perforations. Four of 17 perforations occurred in the posterior part of the cyst wall. Only 1 case of perforation was associated with protein plugs in a common channel, while 7 of the 10 cases of choledochal cyst requiring percutaneous biliary drainage due to signs of raised intrabiliary pressure were found to have protein plugs. We consider that spontaneous perforation of a choledochal cyst is not rare in infancy. The etiology of a perforation must be epithelial irritation of the biliary tract due to refluxed pancreatic juice caused by pancreatico-biliary malunion associated with mural immaturity due to infancy, rather than an abnormal rise in ductal pressure or congenital mural weakness at a certain point.
