Clinical implementation of routine diagnostic laparoscopy to guide initial treatment in patients with advanced-stage epithelial ovarian cancer in Dutch clinical practice: Evaluation of support and a budget impact analysis.

OBJECTIVE: In patients with advanced-stage epithelial ovarian cancer (EOC), a diagnostic laparoscopy (DLS) to determine treatment regime prevents futile laparotomies and seems cost-neutral. The uptake of DLS in current practice is unknown. We evaluated the clinical application of routine DLS in treatment planning in patients with advanced-stage EOC in the Netherlands. METHODS: The implementation was evaluated over the period 2017-2019, using a health technology assessment including clinical, organizational, and economic factors. Barriers for implementation were identified and DLS use was assessed using semi-structured surveys with healthcare professionals. Data from the Dutch Gynecological Oncology Audit were used to determine (un)successful CRS rates. To assess the economic impact, we performed a budget impact analysis (BIA) of the combined interventions of DLS and primary CRS. RESULTS: The DLS use to guide treatment planning increased from 16% to 20%. The majority of the centers did not support routine DLS implementation, mainly because of logistic barriers and its invasive nature. The primary CRS rate of all CRS decreased from 44% to 36%, in favor of interval CRS. The unsuccessful primary CRS rate decreased from 15% to 9% resulting in fewer patients needed a second interval CRS. Consequently, total health care costs decreased from €4.457.496 to €4.274.751. CONCLUSIONS: The implementation of routine DLS for guiding treatment planning in patients with advanced-stage EOC has limited support in the Netherlands. Over the years, total health care costs decreased. For current practice, it is advised that a DLS is useful in case it is uncertain whether a successful primary CRS is feasible based on conventional work-up.

Can serum human epididymis protein 4 (HE4) support the decision to refer a patient with an ovarian mass to an oncology hospital?

INTRODUCTION: The value of serum human epididymis protein 4 (HE4) in guiding referral decisions in patients with an ovarian mass remains unclear, because the majority of studies investigating HE4 were performed in oncology hospitals. However, the decision to refer is made at general hospitals with a low ovarian cancer prevalence. We assessed accuracies of HE4 in differentiating benign or borderline from malignant tumors in patients presenting with an ovarian mass at general hospitals. METHOD: Patients with an ovarian mass were prospectively included between 2017 and 2021 in nine general hospitals. HE4 and CA125 were preoperatively measured and the risk of malignancy index (RMI) was calculated. Histological diagnosis was the reference standard. RESULTS: We included 316 patients, of whom 195 had a benign, 39 had a borderline and 82 had a malignant ovarian mass. HE4 had the highest AUC of 0.80 (95%CI 0.74-0.86), followed by RMI (0.71, 95%CI 0.64-0.78) and CA125 (0.69, 95%CI 0.62-0.75). Clinical setting significantly influenced biomarker performances. Applying age-dependent cut-off values for HE4 resulted in a better performance than one cut-off. Addition of HE4 to RMI resulted in a 32% decrease of unnecessary referred patients, while the number of correctly referred patients remained the same. CONCLUSION: HE4 is superior to RMI in predicting malignancy in patients with an ovarian mass from general hospitals. The addition of HE4 to the RMI improved HE4 alone. Although, there is still room for improvement, HE4 can guide referral decisions in patients with an ovarian mass to an oncology hospital.

An outbreak of hepatitis A virus infection in a secondary school in England with no undetected asymptomatic transmission among students.

In June 2019 the Health Protection Team in Yorkshire and Humber, England, was notified of cases of hepatitis A virus (HAV) infection in staff at a secondary school. Investigation revealed that an earlier case worked as a food handler in the school kitchen. Indirect transmission through food from the canteen was considered the most likely route of transmission. Cases were described according to setting of exposure. Oral fluid was obtained from students for serological testing. Environmental investigations were undertaken at settings where food handling was considered a potential transmission risk. Thirty-three confirmed cases were linked to the outbreak. All of those tested (n = 31) shared the same sequence with a HAV IB genotype. The first three cases were a household cluster and included the index case for the school. A further 19 cases (16 students, 3 staff) were associated with the school and consistent with indirect exposure to the food handler. One late onset case could not be ruled out as a secondary case within the school and resulted in vaccination of the school population. Five cases were linked to a bakery where a case from the initial household cluster worked as a food server. No concerns about hygiene standards were noted at either the school or the bakery. Oral fluid samples taken at the time of vaccination from asymptomatic students (n = 219, 11-16 years-old) showed no evidence of recent or current infection. This outbreak included household and foodborne transmission but limited (and possibly zero) person-to-person transmission among secondary school students. Where adequate hygiene exists, secondary transmission within older students may not occur.

COVID-19: public health management of the first two confirmed cases identified in the UK.

We report key learning from the public health management of the first two confirmed cases of COVID-19 identified in the UK. The first case imported, and the second associated with probable person-to-person transmission within the UK. Contact tracing was complex and fast-moving. Potential exposures for both cases were reviewed, and 52 contacts were identified. No further confirmed COVID-19 cases have been linked epidemiologically to these two cases. As steps are made to enhance contact tracing across the UK, the lessons learned from earlier contact tracing during the country's containment phase are particularly important and timely.

A randomised comparison of the effect of haemodynamic monitoring with CardioMEMS in addition to standard care on quality of life and hospitalisations in patients with chronic heart failure : Design and rationale of the MONITOR HF multicentre randomised clinical trial.

BACKGROUND: Assessing haemodynamic congestion based on filling pressures instead of clinical congestion can be a way to further improve quality of life (QoL) and clinical outcome by intervening before symptoms or weight gain occur in heart failure (HF) patients. The clinical efficacy of remote monitoring of pulmonary artery (PA) pressures (CardioMEMS; Abbott Inc., Atlanta, GA, USA) has been demonstrated in the USA. Currently, the PA sensor is not reimbursed in the European Union as its benefit when applied in addition to standard HF care is unknown in Western European countries, including the Netherlands. AIMS: To demonstrate the efficacy and cost-effectiveness of haemodynamic PA monitoring in addition to contemporary standard HF care in a high-quality Western European health care system. METHODS: The current study is a prospective, multi-centre, randomised clinical trial in 340 patients with chronic HF (New York Heart Association functional class III) randomised to HF care including remote monitoring with the CardioMEMS PA sensor or standard HF care alone. Eligible patients have at least one hospitalisation for HF in 12 months before enrolment and will be randomised in a 1:1 ratio. Minimum follow-up will be 1 year. The primary endpoint is the change in QoL as measured by the Kansas City Cardiomyopathy Questionnaire (KCCQ). Secondary endpoints are the number of HF hospital admissions and changes in health status assessed by EQ-5D-5L questionnaire including health care utilisation and formal cost-effectiveness analysis. CONCLUSION: The MONITOR HF trial will evaluate the efficacy and cost-effectiveness of haemodynamic monitoring by CardioMEMS in addition to standard HF care in patients with chronic HF. Clinical Trial Registration number NTR7672.

Analysis of Bordetella pertussis clinical isolates circulating in European countries during the period 1998-2012.

Despite more than 50 years of vaccination, pertussis is still an endemic disease, with regular epidemic outbreaks. With the exception of Poland, European countries have replaced whole-cell vaccines (WCVs) by acellular vaccines (ACVs) in the 1990s. Worldwide, antigenic divergence in vaccine antigens has been found between vaccine strains and circulating strains. In this work, 466 Bordetella pertussis isolates collected in the period 1998-2012 from 13 European countries were characterised by multi-locus antigen sequence typing (MAST) of the pertussis toxin promoter (ptxP) and of the genes coding for proteins used in the ACVs: pertussis toxin (Ptx), pertactin (Prn), type 2 fimbriae (Fim2) and type 3 fimbriae (Fim3). Isolates were further characterised by fimbrial serotyping, multi-locus variable-number tandem repeat analysis (MLVA) and pulsed-field gel electrophoresis (PFGE). The results showed a very similar B. pertussis population for 12 countries using ACVs, while Poland, which uses a WCV, was quite distinct, suggesting that ACVs and WCVs select for different B. pertussis populations. This study forms a baseline for future studies on the effect of vaccination programmes on B. pertussis populations.

Investigations into the emergence of pertactin-deficient Bordetella pertussis isolates in six European countries, 1996 to 2012.

Pathogen adaptation has been proposed to contribute to the resurgence of pertussis. A striking recent example is the emergence of isolates deficient in the vaccine component pertactin (Prn). This study explores the emergence of such Prn-deficient isolates in six European countries. During 2007 to 2009, 0/83 isolates from the Netherlands, 0/18 from the United Kingdom, 0/17 Finland, 0/23 Denmark, 4/99 Sweden and 5/20 from Norway of the isolates collected were Prn-deficient. In the Netherlands and Sweden, respectively 4/146 and 1/8 were observed in a later period (2010­12). The Prn-deficient isolates were genetically diverse and different mutations were found to inactivate the prn gene. These are indications that Prn-deficiency is subject to positive selective pressure. We hypothesise that the switch from whole cell to acellular pertussis vaccines has affected the balance between 'costs and benefits' of Prn production by Bordetella pertussis to the extent that isolates that do not produce Prn are able to expand. The absence of Prn-deficient isolates in some countries may point to ways to prevent or delay the spread of Prn-deficient strains. In order to substantiate this hypothesis, trends in the European B. pertussis population should be monitored continuously.

Clinical evaluation of a PHMB-impregnated biocellulose dressing on paediatric lacerations.

OBJECTIVE: To evaluate the clinical benefits, primarily tolerability and reduction in pain levels, associated with the use of a PHMB-impregnated biosynthetic cellulose dressing (Suprasorb X + PHMB) on paediatric heel lacerations. METHOD: These lacerations were caused when children, who were being transported on their parents' bicycles, got their heels trapped in the wheel spokes. Where these injuries just comprised skin contusion and laceration, treatment had previously comprised cleansing followed by application of conventional dressings and moist wound healing dressings. However, the high incidence of infection necessitated regular dressing changes, which caused parents and children stress and anxiety. This clinical evaluation assessed the benefits of a new treatment protocol, where the PHMB-impregnated biocellulose dressing was applied and left in situ until epithelialisation occurred. A cork splint was used for 3 days to prevent pes equinus and to let the ankle joint rest. Change in wound size (cm²), incidence of local infection, wound bed characteristics and pain levels (measured on a 0-10 paediatric pain scale) were assessed at 3-day intervals during the 14-day treatment period. Satisfaction with the dressing was also evaluated. RESULTS: Twenty children (mean age 5.6 years (± 1.33) were recruited into the study and included in the analysis. The mean baseline wound area was 8.60cm² (± 6.57). The mean time to complete wound closure was 12.95 days (± 7.69) with a mean total of 4.70 visits (± 1.56). The mean VAS pain score was 9.55 (± 0.69), compared with 0.15 (± 0.37) on day 14 (p<0.003). At the second visit (after 3 days) 17 of the 20 children were reported to be free of pain. No cases of local infection were noted. CONCLUSION: The dressing was found to be child and parent friendly. The evaluation also showed that it was well tolerated and achieved good healing outcome. It has now been incorporated into the clinic's treatment protocol for these wounds. CONFLICT OF INTEREST: None. The authors have no relevant financial interest in this article.

Screening for pulmonary arteriovenous malformations using transthoracic contrast echocardiography: a prospective study.

Pulmonary arteriovenous malformations (PAVMs) are associated with severe neurological complications in patients with hereditary haemorrhagic telangiectasia (HHT). The objective of the present study was to prospectively establish the diagnostic value of transthoracic contrast echocardiography (TTCE) as a screening technique for PAVM using chest high-resolution computed tomography (HRCT) as the gold standard for PAVMs. All consecutive adult patients referred for HHT screening underwent a chest HRCT (n = 299), TTCE (n = 281), arterial blood gas analysis (n = 291), shunt fraction measurement (n = 111) and chest radiography (n = 296). TTCE was positive in 87 (58.8%), 12 (16.7%) and four (6.7%) patients, and chest HRCT was positive in 54 (36.5%), three (4.2%) and zero (0%) patients with a definite, possible and negative clinical diagnosis of HHT, respectively. Two patients with a negative TTCE were diagnosed with PAVMs after computed tomography; in both cases the PAVMs were too small to be treated by embolotherapy. The sensitivity of TTCE was 97% (95% confidence interval (CI) 93.6-98.3) and negative predictive value 99% (95% CI 96.9-99.8). The other diagnostic tests showed a considerable lower diagnostic value. The present prospective study shows that transthoracic contrast echocardiography has an excellent diagnostic value and can be used as an initial screening procedure for pulmonary arteriovenous malformations. The high false-positive rate of transthoracic contrast echocardiography possibly represents microscopic pulmonary arteriovenous malformations.

Pulmonary arteriovenous malformations associated with migraine with aura.

Migraine with aura (MA) is associated with cardiac right-to-left shunt. We prospectively studied the association between pulmonary arteriovenous malformations (PAVMs) and MA in hereditary haemorrhagic telangiectasia (HHT). All 220 consecutive HHT patients who underwent high-resolution chest computed tomography for PAVM screening were included prospectively. Prior to screening, a structured validated headache questionnaire was completed by 196 patients (57% female; mean+/-sd age 44.6+/-15.2 yrs). Two neurologists diagnosed migraine according to the International Headache Society Criteria. A PAVM was present in 70 (36%) patients. The prevalence of MA was 24% in the presence of a PAVM compared with 6% in the absence of a PAVM (OR 4.6, 95% CI 1.84-11.2; p = 0.001), and MA was an independent predictor for the presence of PAVM using multivariate analysis (OR 3.6, 95% CI 1.21-10.5; p = 0.02). A PAVM was present in 68% of the patients with MA compared with 32% in the non-migraine controls (OR 4.6, 95% CI 1.84-11.2; p = 0.001), and a PAVM was an independent predictor for MA using multivariate analysis (OR 3.0, 95% CI 1.00-9.20; p = 0.05). In conclusion, PAVMs are associated with MA in HHT patients.

Effects of cyclosporine immunosuppression in insulin-dependent diabetes mellitus of recent onset.

Type I diabetes may be an autoimmune disorder, although the evidence is largely circumstantial. The natural history of the disease after diagnosis includes partial remission in most patients, but only about 3 percent achieve transient insulin independence. beta Cell function, as indicated by the plasma concentration of C-peptide, is lost over 6 to 30 months and islet cell antibodies disappeared over 1 to 2 years. This article describes a pilot study in which 41 patients were treated with the immunosuppressive agent cyclosporine for 2 to 12 months. Of 30 patients treated within 6 weeks of diagnosis, 16 became insulin independent with concentrations of plasma C-peptide in the normal range and decreasing titers of islet cell antibodies. Of 11 patients who entered the study 8 to 44 weeks after diagnosis, two achieved this state. These results indicate that a controlled trial of the effects of cyclosporine in type I diabetes should be conducted.

Pulmonary arteriovenous malformations and migraine: a new vision.

Migraine is a common neurological disorder with a great impact on the quality of life and social activities. Pulmonary arteriovenous malformations (PAVMs) are mostly congenital, with a prevalence of 5-50% in patients with hereditary hemorrhagic telangiectasia (HHT). A high prevalence of PAVMs is found in patients with HHT and migraine. Embolization of PAVMs seems to decrease the prevalence of migraine. Different pathophysiological hypotheses have been proposed to explain the association between migraine and the different right-to-left shunts. This review article describes the association between a pulmonary right-to-left shunt and the occurrence of migraine.

[Subarachnoid haemorrhage presenting clinically as circulatory arrest in acute myocardial infarction]. / Subarachnoïdale bloeding met de klinische presentatie van een circulatiestilstand bij acuut myocardinfarct.

A 59-year-old woman and a 41-year-old man were both brought to the Cardiac Emergency Clinic with circulatory arrest on the basis ofpulseless electrical activity. The first patient had had no prodromal symptoms and the second patient had visited his general practitioner 2 weeks earlier because of pain in the head and neck. In both patients, electrocardiography and echocardiography suggested acute myocardial infarction. However, both patients proved to be suffering from a subarachnoid haemorrhage (SAH) and both died. One-third ofthe patients with SAH are comatose at presentation. Cardiac manifestations such as ECG-abnormalities, cardiac arrhythmias, cardiopulmonary arrest, elevated troponin values, and signs of left ventricular dysfunction are common. These findings can be misleading and may have catastrophic consequences if anticoagulant therapy is initiated because of a presumed myocardial infarction. Low-threshold CT-scanning of the brain is therefore advised for patients who remain comatose after resuscitation for cardiac arrest in the presence of an atypical anamnesis.

Enhanced platelet accumulation onto injured carotid arteries in rabbits after aspirin treatment.

Prostacyclin (PGI2) is a powerful inhibitor of platelet aggregation, but its role in the pathogenesis of arterial thrombosis is uncertain. We have studied the thrombogenic effect of inhibiting PGI2 production by aspirin (ASA) in carotid arteries of rabbits given 0, 3, 10, or 100 mg ASA/kg either 1, 3, 6, or 20 h beforehand. Platelet accumulation onto injured carotid arteries was enhanced with ASA in a dose of 10 mg/kg. A higher dose of ASA (100 mg/kg) had no further effect. The enhanced thrombogenic effect of ASA persisted for at least 20 h and was associated with a decrease in vessel wall PGI2 production. There was a strong inverse correlation (r = 0.55, P less than 0.01) between PGI2 production and platelet accumulation. The findings suggest that the margin of safety in obtaining an antithrombotic effect of ASA and producing a potential thrombotic effect in arteries may not be as large as predicted by studies using cultured endothelial cells or experimentally induced thrombosis in veins.

Resolution of experimental pulmonary emboli with heparin and streptokinase in different dosage regimens.

Thrombolytic agents may be useful in acute pulmonary embolism, but their optimal dosage remains uncertain. We have examined the relative efficacy of heparin and different doses of streptokinase, either alone or in combination, in acute experimental pulmonary embolism. A standardized massive embolus of autologous blood clot incorporating canine [(125)I]-fibrinogen was given to 40 dogs; the degree of resolution after 24 h was quantitated by measuring the radioactivity in the lungs and was compared with detailed postmortem observations. The amount of residual embolus was 49% in control animals, 28% after heparin (200 U/kg loading dose and 800 U/kg/24 h maintenance dose), and 6% after high dose streptokinase (250,000 U loading dose and 100,000 U/h maintenance dose); it was 31% after low dose streptokinase (25,000 U loading dose and 10,000 U/h maintenance dose), 7% after low dose streptokinase with heparin, 14% after very low dose streptokinase (5,000 U/h without a loading dose) with heparin, and 9% after short course streptokinase (250,000 U loading dose and no maintenance dose) with heparin. The combination of heparin and low doses or brief courses of streptokinase appeared to be synergistic and produced as much resolution as did standard high dose streptokinase alone. The enhanced resolution of pulmonary emboli in heparin-treated animals may have been due to the prevention by heparin of further deposition of fibrin on the embolus. It appears that dosage regimens of thrombolytic therapy other than those in current use may be worthy of clinical examination.

The effect of thrombocytopenia on experimental arteriosclerotic lesion formation in rabbits. Smooth muscle cell proliferation and re-endothelialization.

This study was designed to investigate the mechanisms involved in fibromusculoelastic lesion formation produced by selective de-endothelialization by the intra-arterial balloon catheter technique in thrombocytopenic rabbits. Thrombocytopenia was induced and maintained for up to 30 days by daily injections fo highly specific sheep anti-rabbit platelet sera (APS). Evidence for re-endothelialization was obtained by i.v. Evans blue dye 30 min before sacrifice. Rabbits received daily injections of APS, which reduced the mean platelet count to 5,600/cm3; control animals received identically treated normal sheep sera on the same schedule, and had mean daily platelet counts of 363,000/cm3. Evaluation of intimal thickness was assessed by counting cell layers in semithin sections. Intimal thickening in aortae from rabbits treated with APS was strikingly suppressed, in contrast to those from normal sheep sera-treated animals which showed a mean intimal thickness of 18 cell layers within 28 days often after de-endothelialization. Re-endothelialization was not affected by APS treatment. These results indicate that the proliferation of smooth muscle cells is dramatically inhibited by reduction of platelets.

Subcutaneous fondaparinux versus intravenous unfractionated heparin in the initial treatment of pulmonary embolism.

BACKGROUND: The standard initial treatment of hemodynamically stable patients with pulmonary embolism is intravenous unfractionated heparin, requiring laboratory monitoring and hospitalization. METHODS: We conducted a randomized, open-label trial involving 2213 patients with acute symptomatic pulmonary embolism to compare the efficacy and safety of the synthetic antithrombotic agent fondaparinux with those of unfractionated heparin and to document noninferiority in terms of efficacy. Patients received either fondaparinux (5.0, 7.5, or 10.0 mg in patients weighing less than 50, 50 to 100, or more than 100 kg, respectively) subcutaneously once daily or a continuous intravenous infusion of unfractionated heparin (ratio of the activated partial-thromboplastin time to a control value, 1.5 to 2.5), both given for at least five days and until the use of vitamin K antagonists resulted in an international normalized ratio above 2.0. The primary efficacy outcome was the three-month incidence of the composite end point of symptomatic, recurrent pulmonary embolism (nonfatal or fatal) and new or recurrent deep-vein thrombosis. RESULTS: Forty-two of the 1103 patients randomly assigned to receive fondaparinux (3.8 percent) had recurrent thromboembolic events, as compared with 56 of the 1110 patients randomly assigned to receive unfractionated heparin (5.0 percent), for an absolute difference of -1.2 percent in favor of fondaparinux (95 percent confidence interval, -3.0 to 0.5). Major bleeding occurred in 1.3 percent of the patients treated with fondaparinux and 1.1 percent of those treated with unfractionated heparin. Mortality rates at three months were similar in the two groups. Of the patients in the fondaparinux group, 14.5 percent received the drug in part on an outpatient basis. CONCLUSIONS: Once-daily, subcutaneous administration of fondaparinux without monitoring is at least as effective and is as safe as adjusted-dose, intravenous administration of unfractionated heparin in the initial treatment of hemodynamically stable patients with pulmonary embolism.

Fondaparinux combined with intermittent pneumatic compression vs. intermittent pneumatic compression alone for prevention of venous thromboembolism after abdominal surgery: a randomized, double-blind comparison.

BACKGROUND: The benefit of combined mechanical and pharmacologic methods for venous thromboembolism prevention after abdominal surgery has not been clearly established. OBJECTIVES: To compare the efficacy and safety of fondaparinux in conjunction with intermittent pneumatic compression vs. intermittent pneumatic compression alone in this context. PATIENTS AND METHODS: This was a randomized, double-blind, placebo-controlled superiority trial. Patients aged at least 40 years undergoing abdominal surgery were randomized to receive either fondaparinux 2.5 mg or placebo s.c. for 5-9 days, starting 6-8 h postoperatively. All patients received intermittent pneumatic compression. The primary efficacy outcome was venous thromboembolism up to day 10. The main safety outcomes were major bleeding and all-cause mortality. Follow-up lasted 32 days. RESULTS: Of the 1309 patients randomized, 842 (64.3%) were evaluable for efficacy. The venous thromboembolism rate was 1.7% (7/424) in the fondaparinux-treated patients and 5.3% (22/418) in the placebo-treated patients (odds ratio reduction 69.8%; 95% confidence interval 27.9-87.3; P = 0.004). Fondaparinux significantly reduced the proximal deep vein thrombosis rate from 1.7% (7/417) to 0.2% (1/424; P = 0.037). Major bleeds occurred in 1.6% (10/635) and 0.2% (1/650) of fondaparinux-treated and placebo-treated patients, respectively (P = 0.006), none being fatal or involving a critical organ. By day 32, eight patients (1.3%) receiving fondaparinux and five (0.8%) receiving placebo had died. CONCLUSIONS: In patients undergoing abdominal surgery and receiving intermittent pneumatic compression, fondaparinux 2.5 mg reduced the venous thromboembolism rate by 69.8% as compared to pneumatic compression alone, with a low bleeding risk as compared to placebo.

Effect of obesity on outcomes after fondaparinux, enoxaparin, or heparin treatment for acute venous thromboembolism in the Matisse trials.

BACKGROUND: Selecting initial anticoagulant dose by patient weight for acute pulmonary embolism and deep vein thrombosis has clinical credibility; however, uncertainty remains regarding how to dose obese patients with newer anticoagulants because outcome data are sparse. OBJECTIVES: To use the Matisse trials' comparison of sc fondaparinux once daily with control heparin therapies (intravenous unfractionated heparin for pulmonary embolism, sc enoxaparin 1 mg/kg b.i.d. for deep vein thrombosis) for initial treatment in order to compare primary outcomes (venous thromboembolism recurrence and major bleeding) in obese patients. PATIENTS AND METHODS: Primary outcomes were compared in subsets composed of patients weighing < or = and > 100 kg and with body mass index (BMI) < 30 and > or = 30 kg/m(2). Medians and ranges for weight and BMI were compared for patients suffering either recurrence or major bleeding. RESULTS: Twenty-two thousand and one patients received fondaparinux and 2217 received enoxaparin or unfractionated heparin. Four hundred and ninety-six patients (11%) weighed > 100 kg and 1216 (28%) had a BMI > or = 30. Treatment groups had similar characteristics. The upper limit in subject weight for recurrence was 166 kg (BMI 58), and for major bleeding 120 kg (BMI 39). The incidences of recurrence and major bleeding were similar for each patient subset of weight and BMI for both fondaparinux and heparin treatment groups. Among patients with a primary outcome, median weights and BMIs were also similar. CONCLUSIONS: The current recommended doses of fondaparinux and heparins for the treatment of venous thromboembolism appear to provide similar protection against recurrence and major bleeding to one another and to obese and non-obese patients.

[Manifest carcinoma of the glandula vestibularis major (Bartholin's gland), detected one year after an inguinal lymph-node metastasis]. / Manifest carcinoom van de glandula vestibularis major (Bartholini), gedetecteerd één jaar na een lieskliermetastase.

A 68-year-old woman had had a TNM stage-III rectal carcinoma at the age of 54 for which she had undergone a low anterior resection followed by postoperative radiotherapy and adjuvant chemotherapy with fluorouracil and levamisol. More than 10 years later she presented with a swelling in the right groin, which turned out to be a metastasis; this was a poorly differentiated carcinoma with some of the characteristics of a transitional epithelial carcinoma, for which no primary tumour was found. The lymph node was excised. One year later, a swelling was detected on the labium majus, caused by a poorly differentiated transitional epithelial carcinoma of the glandula vestibularis major (Bartholin's gland). The patient was treated by means ofhemivulvectomy and postoperative radiotherapy.
