Women who smoke during pregnancy are more likely to be referred to an obstetrician during pregnancy and birth: results from a cohort study. BMC Pregnancy Childbirth 2022; 22:479. [PMID: 35698051 PMCID: PMC9190098 DOI: 10.1186/s12884-022-04808-7] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/30/2021] [Accepted: 06/03/2022] [Indexed: 11/13/2022] Open
Abstract
Background Women who smoke during pregnancy make less use of prenatal care; the relation of smoking behavior with the use of other forms of maternal healthcare is unknown. The objective of this study is to investigate the association between women’s smoking behavior and their use of healthcare during pregnancy, birth and six weeks postpartum. Methods We analyzed data from the Dutch Midwifery Case Registration System (VeCaS), period 2012–2019. We included women with a known smoking status, singleton pregnancies, and who had their first appointment before 24 weeks of gestation with the primary care midwife. We compared three groups: non-smokers, early stoppers (stopped smoking in the first trimester), and late- or non-stoppers (stopped smoking after the first trimester or continued smoking). Descriptive statistics were used to report maternal healthcare utilization (during pregnancy, birth and six weeks postpartum), statistical differences between the groups were calculated with Kruskal–Wallis tests. Multivariable logistic regression was conducted to assess the association between smoking behavior and referrals to primary, secondary or tertiary care. Results We included 41 088 pregnant women. The groups differed significantly on maternal healthcare utilization. The late- or non-stoppers initiated prenatal care later and had less face-to-face consultations with primary care midwives during pregnancy. Compared to the non-smokers, the early- and late- or non-stoppers were statistically signficiantly more likely to be referred to the obstetrician during pregnancy and birth. Postpartum, the early- and late- or non-stoppers were statistically signficantly less likely to be referred to the obstetrician compared to the non-smokers. Conclusions Although the early- and late- or non-stoppers initiated prenatal care later than the non-smokers, they did receive adequate prenatal care (according to the recommendations). The results suggest that not smoking during pregnancy may decrease the likelihood of referral to secondary or tertiary care. The large population of smokers being referred during pregnancy underlines the important role of the collaboration between healthcare professionals in primary and secondary or tertiary care. They need to be more aware of the importance of smoking as a medical and as a non-medical risk factor.

Rotavirus and illness severity in children presenting with acute gastroenteritis at the primary care out-of-hours service. Eur J Gen Pract 2021; 27:346-353. [PMID: 34894994 PMCID: PMC8741236 DOI: 10.1080/13814788.2021.2011205] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/12/2021] [Revised: 11/16/2021] [Accepted: 11/19/2021] [Indexed: 10/24/2022] Open
Abstract
BACKGROUND Rotavirus is a common cause of acute gastroenteritis in young children in the Netherlands, where rotavirus vaccination has not yet been implemented. OBJECTIVES To evaluate a difference in illness severity course depending on the presence of rotavirus infection and assess the prevalence of viruses and the referral rate in children with acute gastroenteritis. METHODS A prospective cohort of children aged 6 months to 6 years presenting with acute gastroenteritis to a primary care out-of-hours service from October 2016 to March 2018. Faeces were sampled and sent to a laboratory where viral pathogens were identified and quantified by real-time polymerase chain reaction. Severe course of acute gastroenteritis was defined as a Modified Vesikari Score of ≥11. In addition, we assessed referral rates. Chi-square tests were used to evaluate differences between groups. RESULTS We included 75 children (34 boys) with a median age of 1.5 years (interquartile range, 0.9-2.0 years). The prevalence of rotavirus was 65.3% (95% confidence interval, 53.5-76.0) with a median cycle threshold of 16.0. Severe course of acute gastroenteritis was present in 31 of 71 children (4 were lost to follow-up). Those with rotavirus (20/47) did not have a severe course more often than those without (11/24): odds ratio, 0.88 (95% confidence interval, 0.33-2.36). Referral rates were comparable for rotavirus (15.2%) and non-rotavirus (14.3%). CONCLUSION In out-of-hours primary care, rotavirus is common but not associated with increased severity and higher referral rates in children with acute gastroenteritis.

Abstract
Objective To evaluate the costs and non‐inferiority of a strategy starting with the levonorgestrel intrauterine system (LNG‐IUS) compared with endometrial ablation (EA) in the treatment of heavy menstrual bleeding (HMB). Design Cost‐effectiveness analysis from a societal perspective alongside a multicentre randomised non‐inferiority trial. Setting General practices and gynaecology departments in the Netherlands. Population In all, 270 women with HMB, aged ≥34 years old, without intracavitary pathology or wish for a future child. Methods Randomisation to a strategy starting with the LNG‐IUS (n = 132) or EA (n = 138). The incremental cost‐effectiveness ratio was estimated. Main outcome measures Direct medical costs and (in)direct non‐medical costs were calculated. The primary outcome was menstrual blood loss after 24 months, measured with the mean Pictorial Blood Assessment Chart (PBAC)‐score (non‐inferiority margin 25 points). A secondary outcome was successful blood loss reduction (PBAC‐score ≤75 points). Results Total costs per patient were €2,285 in the LNG‐IUS strategy and €3,465 in the EA strategy (difference: €1,180). At 24 months, mean PBAC‐scores were 64.8 in the LNG‐IUS group (n = 115) and 14.2 in the EA group (n = 132); difference 50.5 points (95% CI 4.3–96.7). In the LNG‐IUS group, 87% of women had a PBAC‐score ≤75 points versus 94% in the EA group (relative risk [RR] 0.93, 95% CI 0.85–1.01). The ICER was €23 (95% CI €5–111) per PBAC‐point. Conclusions A strategy starting with the LNG‐IUS was cheaper than starting with EA, but non‐inferiority could not be demonstrated. The LNG‐IUS is reversible and less invasive and can be a cost‐effective treatment option, depending on the success rate women are willing to accept. Tweetable abstract Treatment of heavy menstrual bleeding starting with LNG‐IUS is cheaper but slightly less effective than endometrial ablation. Treatment of heavy menstrual bleeding starting with LNG‐IUS is cheaper but slightly less effective than endometrial ablation.

Abstract
Abstract
Introduction
Despite the health risks of smoking, some women continue smoking during pregnancy. Professional smoking cessation support (SCS) has shown to be effective in increasing the proportion of women who quit smoking during pregnancy. However, few women actually make use of professional SCS. The aim of this study is to investigate the needs of women and their partners for professional SCS.
Methods
Semi-structured interviews were held with pregnant women and recent mothers who smoked or quit smoking during pregnancy, and their partners, living in the North of the Netherlands. Recruitment was done via Facebook, LinkedIn, food banks, baby stores and healthcare professionals. The interviews were recorded, transcribed and thematically analyzed.
Results
28 interviews were conducted, 23 with pregnant women and recent mothers, and five with partners of the women. The following themes were identified: 1) Understanding women's needs, 2) Responsibility without criticism, and 3) Women and their social network. These themes reflect that women need support from an involved and understanding healthcare professional, who holds women responsible for smoking cessation but refrains from criticism. Women also prefer involvement of their social network in the professional support.
Conclusions
For tailored support, the guideline for professional SCS may need some adaptations, and women and their partners should be involved in the development of future guidelines. Women prefer healthcare professionals to address smoking cessation in a neutral way and to respect their autonomy in the decision to stop smoking.

The effect of physical activity on fatigue among survivors of colorectal cancer: a systematic review and meta-analysis. Support Care Cancer 2017; 26:393-403. [PMID: 29058127 PMCID: PMC5752739 DOI: 10.1007/s00520-017-3920-4] [Citation(s) in RCA: 23] [Impact Index Per Article: 3.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/19/2017] [Accepted: 10/02/2017] [Indexed: 12/24/2022]
Abstract
PURPOSE Favorable health outcomes among cancer survivors are increasingly being attributed to lifestyle factors like physical activity, which is now promoted in clinical guidelines. However, the available evidence indicates that physical activity may also reduce fatigue in this patient group. In this systematic review, we aimed to examine whether physical activity could reduce fatigue among survivors of colorectal cancer. METHODS The databases of Medline, CINAHL, and PsycINFO were systematically searched, using combinations of MeSH and free-text terms for colorectal cancer, physical activity, and fatigue. Randomized controlled trials and cohort studies with longitudinal data collection were included. We performed a random-effect meta-analysis. RESULTS Seven studies were included, five were randomized controlled trials, and two were cohort studies. A meta-analysis of the randomized controlled trials, which comprised 630 survivors in total, failed to show that physical activity had a significant effect on fatigue (standardized mean difference = 0.21 (- 0.07 to 0.49)); however, reduced levels of fatigue were observed in all studies. The results for the cohort studies were inconclusive: one showed that increasing levels of physical activity were significantly associated with decreasing levels of fatigue; the other showed that decreasing levels of fatigue were not associated with increasing levels of physical activity. CONCLUSIONS Based on the data reviewed, we cannot draw definitive conclusions about the effects of physical activity on fatigue. None of the included studies were performed among fatigued survivors of colorectal cancer. More research is needed in this population, ensuring that the trials are appropriately powered to find differences in fatigue.

Abstract
Screening for colorectal cancer (CRC) has both advantages (e.g. reduction in morbidity and mortality) and disadvantages (e.g. false positives and distress). A systematic review was therefore performed to improve our understanding of how false-positive CRC screening results affect patients psychologically (and to make recommendations for primary care). The PubMed, Embase, PsychINFO, CINAHL and Cochrane databases were searched in October 2014 and supplemented in December 2016 to identify studies on the psychological impact of false-positive CRC screening. Original studies were eligible when they assessed psychological impact in a screening setting, provided they also included false-positive CRC screening results. Two authors independently assessed 2,367 available manuscripts and included seven. Heterogeneity in their outcome measures meant that data could not be pooled. Two studies showed that a false-positive CRC screening result caused some moderate psychological distress shortly before and after colonoscopy. The remaining five studies illustrated that the psychological distress of patients with true-positive and false-positive CRC screening results was comparable. We conclude that a false-positive CRC screening result may cause some moderate psychological distress, especially just before or after colonoscopy. We recommend that general practitioners mention this when discussing CRC screening with patients and monitor those with a false-positive outcome for psychological distress.

Abstract
Asymptomatic microscopic haematuria is a common finding and can have many different causes. Only a small fraction of patients referred for microscopic haematuria have an underlying urological malignancy or serious nephrogenic disease. It is important that only those patients with microscopically confirmed microscopic haematuria are referred. Often no cause can be found even after thorough diagnostic work-up. The work-up of microscopic haematuria can include urethrocystoscopy, ultrasound, multi-phase CT and cytology. These procedures are not only costly, but can have associated health risks and may also cause patients anxiety and distress. There is no evidence to support the hypothesis that microscopic haematuria is the precursor of macroscopic haematuria, which is significantly more likely to have serious underlying causes. A diagnostic work-up should be initiated with caution.

Abstract
The aim of this study was to assess the efficacy of pharmacological prophylactic treatments of migraine in children. Databases were searched from inception to June 2004 and references were checked. We selected controlled trials on the effects of pharmacological prophylactic treatments in children with migraine. We assessed trial quality using the Delphi list and extracted data. Analyses were carried out according to type of intervention. A total of 20 trials were included. Headache improvement was significantly higher for flunarizine compared with placebo (relative risk 4.00, 95% confidence interval 1.60, 9.97). There is conflicting evidence for the use of propranolol. Nimodipine, clonidine, L-5HTP, trazodone and papaverine showed no effect when compared with placebo. All medications were well tolerated and adverse events showed no significant differences. Flunarizine may be effective as prophylactic treatment for migraine in children. Because of the small number of studies and the methodological shortcomings, conclusions regarding effectiveness have to be drawn with caution.

Abstract
OBJECTIVE To compare effects and cost-effectiveness of pelvic floor muscle training (PFMT) and watchful waiting in women with pelvic organ prolapse. DESIGN Randomised controlled trial. SETTING Dutch general practice. POPULATION Women (≥55 years) with symptomatic mild prolapse, identified by screening. METHODS Linear multilevel analysis. MAIN OUTCOME MEASURES Primary outcome was change of pelvic floor symptoms (Pelvic-Floor-Distress-Inventory-20 [PFDI-20]) during 24 months. Secondary outcomes were condition-specific and general quality of life, costs, sexual functioning, prolapse stage, pelvic floor muscle function and women's perceived improvement of symptoms. RESULTS PFMT (n = 145) resulted in a 12.2-point (95% CI 7.2-17.2, P < 0.001) greater improvement in PFDI-20 score during 24 months compared with watchful waiting (n = 142). Participants randomised to PFMT more often reported improved symptoms (43% versus 14% for watchful waiting). Direct medical costs per person were €330 for PFMT and €91 for watchful waiting but costs for absorbent pads were lower in the PFMT group (€40 versus €77). Other secondary outcomes did not differ between groups. Post-hoc subgroup analysis demonstrated that PFMT was more effective in women experiencing higher pelvic floor symptom distress at baseline. CONCLUSION PFMT resulted in greater pelvic floor symptom improvement compared with watchful waiting. The difference was statistically significant, but below the presumed level of clinical relevance (15 points). PFMT more often led to women's perceived improvement of symptoms, lower absorbent pads costs, and was more effective in women experiencing higher pelvic floor symptom distress. Therefore, PFMT could be advised in women with bothersome symptoms of mild prolapse. TWEETABLE ABSTRACT Pelvic floor muscle training can be effective in women with bothersome symptoms of mild prolapse.

Abstract
The Netherlands Federation of University Medical Centres (NFU) has published a report 'Research Agenda for Sustainable Health', in which the authors outline the Netherlands' medical scientific agenda for the coming years. Although this is a laudable initiative, we question the sustainability of this agenda, which seems to promise a world without disease thanks to the efforts of medical researchers as they delve deep into the human genome and cellular mechanisms. In our opinion, putting this agenda into practice will not address many of the current health problems, and the underlying causes of these problems, with which patients and doctors struggle daily. Moreover, this agenda might strengthen expectations of what doctors and patients can achieve, which are already too high.

Abstract
BACKGROUND Around the world, maternal psychopathology during pregnancy is associated with a range of negative consequences for mother and child. Nevertheless, in Central America the magnitude of this public health problem is still unknown. The objective of this first explorative study was to investigate the prevalence and severity of anxiety and depression during pregnancy in the Central American developing country Nicaragua, as well as the availability of mental health care and to compare with a developed country. METHODS A population-based cohort of pregnant women in Nicaragua (N = 98) was compared with a parallel cohort in the Netherlands (N = 4725) on symptoms of anxiety (Spielberger State Trait Anxiety Inventory) and depression (Edinburgh Postnatal Depression Scale). Associations with the women's knowledge how to reach professional psychological support were assessed using multivariable linear regression analyses. RESULTS Of the Nicaraguan women, 41 % had symptoms of anxiety and 57 % symptoms of depression, versus 15 % and 6 % of the Dutch women. Symptom scores of both anxiety and depression were significantly higher in Nicaragua (p < 0.001). However, only 9.6 % of the women indicated that professional psychological help was available for the Nicaraguan pregnant women, which was associated with an increased anxiety score. CONCLUSIONS In Nicaragua, both prevalence and severity of symptoms of antenatal anxiety and depression are substantially higher than in developed countries. However, availability of psychological help is very limited for pregnant Nicaraguan women. These findings indicate that there is need for further research and support for these women, to prevent negative consequences for both mother and child.

Abstract
BACKGROUND One of the long-term effects in childhood cancer survivors (CCS) is the development of second cancers. In a cohort of CCS, this study describes how second cancers were presented, the way they were diagnosed, and the knowledge CCS had about their increased risk to develop a second cancer. PATIENTS AND METHODS Selected participants were all adult five-year CCS (n = 1275) who were treated at the University Medical Center Groningen since 1965. Of these, 84 (6.6%) had developed a second cancer, of which 27 had died. The 57 survivors were asked to participate in a telephone interview. RESULTS Of the 57 CCS, 35 (61%) participated. Together they had developed 45 second cancers. Most participants (97%) were seen at the long-term follow-up clinic. Of all second cancers, 89% caused symptoms. Of all second cancers, the majority (56%) were first presented at the general practitioner's (GP's) office and 20% at follow-up testing. Of these CCS, only 28% were aware of their increased risk of developing a second cancer. CONCLUSIONS It is important to inform CCS continuously regarding their increased risk, as a relatively small percentage are aware of this. Since most of these patients first reported their symptoms to the GP, all GPs should be aware of this increased risk, in particular because this concerns cancer at a younger age than normally expected. A survivor care plan might be an effective way of communication with both CCS and GPs.

Abstract
BACKGROUND Although back pain is common among older people, limited information is available about the characteristics of these patients in primary care. Earlier research suggests that the severity of back symptoms increases with older age. METHODS Patients aged >55 years visiting a general practitioner with a new episode of back pain were included in the BACE study. Information on patients' characteristics, characteristics of the complaint and physical examination were derived from the baseline measurement. Cross-sectional differences between patients aged >55-74 and ≥75 years were analysed using an unpaired t-test, Mann-Whitney U-test or a chi-square test. RESULTS A total of 675 back pain patients were included in the BACE study, with a median age of 65 (interquartile range 60-71) years. Patients aged >55-74 years had a mean disability score (measured with the Roland Disability Questionnaire) of 9.4 [standard deviation (SD) 5.8] compared with 12.1 (SD 5.5) in patients aged ≥75 years (p ≤ 0.01). The older group reported more additional musculoskeletal disorders and more often had low bone quality (based on ultrasound measurement of the heel) than patients aged >55-74 years. Average back pain severity over the previous week showed no difference (p = 0.11) between the age groups, but severity of back pain at the moment of filling in the questionnaire was higher (p = 0.03) in the older age group. CONCLUSIONS In this study, older back pain patients reported more disabilities and co-morbidity. However, the clinical relevance of these differences for the course of the back pain episode in older patients remains a subject for further research.

Abstract
OBJECTIVE To assess the effectiveness of supervised exercise therapy compared with usual care with respect to recovery, pain, and function in patients with patellofemoral pain syndrome. DESIGN Open label randomised controlled trial. SETTING General practice and sport physician practice. PARTICIPANTS Patients with a new episode of patellofemoral pain syndrome recruited by their general practitioner or sport physician. INTERVENTIONS The intervention group received a standardised exercise programme for 6 weeks tailored to individual performance and supervised by a physical therapist, and were instructed to practise the tailored exercises at home for 3 months. The control group were assigned usual care, which comprised a "wait and see" approach of rest during periods of pain and refraining from pain provoking activities. Both the intervention group and the control group received written information about patellofemoral pain syndrome and general instructions for home exercises. MAIN OUTCOME MEASURES The primary outcomes were self reported recovery (7 point Likert scale), pain at rest and pain on activity (0-10 point numerical rating scale), and function (0-100 point Kujala patellofemoral score) at 3 months and 12 months follow-up. RESULTS A total of 131 participants were included in the study: 65 in the intervention group and 66 in the control group. After 3 months, the intervention group showed better outcomes than the control group with regard to pain at rest (adjusted difference -1.07, 95% confidence interval -1.92 to -0.22; effect size 0.47), pain on activity (-1.00, -1.91 to -0.08; 0.45), and function (4.92, 0.14 to 9.72; 0.34). At 12 months, the intervention group continued to show better outcomes than the control group with regard to pain (adjusted difference in pain at rest -1.29, -2.16 to -0.42; effect size 0.56; pain on activity -1.19, -2.22 to -0.16; effect size 0.54), but not function (4.52, -0.73 to 9.76). A higher proportion of patients in the exercise group than in the control group reported recovery (41.9% v 35.0% at 3 months and 62.1% v 50.8% at 12 months), although the differences in self reported recovery between the two groups were not statistically significant. Predefined subgroup analyses revealed that patients recruited by sport physicians (n=30) did not benefit from the intervention, whereas those recruited by general practitioners (n=101) showed significant and clinically relevant differences in pain and function in favour of the intervention group. CONCLUSION Supervised exercise therapy resulted in less pain and better function at short term and long term follow-up compared with usual care in patients with patellofemoral pain syndrome in general practice. Exercise therapy did not produce a significant difference in the rate of self reported recovery. TRIAL REGISTRATION ISRCTN83938749.

Abstract
OBJECTIVE To assess the prognostic value of the clinical American College of Rheumatism (ACR) classification criteria of knee osteoarthritis (OA) on persisting knee complaints and increase of disability in adult patients with knee pain in general practice after 1-year follow-up. METHODS Patients (aged >35 years) consulting for non-traumatic knee complaints in general practice were enrolled in the study. At baseline and 1-year follow-up knee complaints and function were assessed by questionnaires and a physical examination was performed. The prognostic value of fulfilling the clinical ACR criteria of knee OA at baseline on the outcomes persisting knee complaints and increase of disability was determined. RESULTS 549 patients were included in the study of which 480 (87.4%) were available for follow-up. The studied population consisted of 236 (49.2%) women with mean age 53.6 [standard deviation (sd) 11.3], mean body mass index (BMI) 27.1 (sd 4.2), 288 (60.0%) patients had payed employment, and 292 (60.8%) patients fulfilled the clinical ACR criteria of knee OA. After 1-year follow-up, 236 (49.2%) patients reported persisting knee complaints, and 84 (17.5%) reported an increase of disability. There was no association of fulfilling the clinical ACR criteria of knee OA at baseline with persisting knee complaints [odds ratio (OR) 1.15; 95% Confidence Interval (CI) 0.80; 1.67] or increase of disability (OR 1.05; 95% CI 0.43; 2.58) at follow-up. CONCLUSION The clinical ACR classification criteria of knee OA have no prognostic value for predicting persisting knee complaints or an increase of disability at 1-year of follow-up in adult patients with non-traumatic knee complaints in GP.

Abstract
INTRODUCTION Constipation is a common complaint in children and early intervention with oral laxatives may improve complete resolution of functional constipation. However, most treatment guidelines are based on reviews of the literature that do not incorporate a quality assessment of the studies. OBJECTIVE To investigate and summarise the quantity and quality of the current evidence for the effect of laxatives and dietary measures on functional childhood constipation. METHODS The Medline and Embase databases were searched to identify studies evaluating the effect of a medicamentous treatment or dietary intervention on functional constipation. Methodological quality was assessed using a validated list of criteria. Data were statistically pooled, and in case of clinical heterogeneity results were summarised according to a best evidence synthesis. RESULTS Of the 736 studies found, 28 met the inclusion criteria. In total 10 studies were of high quality. The included studies were clinically and statistically heterogeneous in design. Most laxatives were not compared to placebo. Compared to all other laxatives, polyethylene glycol (PEG) achieved more treatment success (pooled relative risk (RR): 1.47; 95% CI 1.23 to 1.76). Lactulose was less than or equally effective in increasing the defecation frequency compared to all other laxatives investigated. There was no difference in effect on defecation frequency between fibre and placebo (weighted standardised mean difference 0.35 bowel movements per week in favour of fibre, 95% CI -0.04 to 0.74). CONCLUSION Insufficient evidence exists supporting that laxative treatment is better than placebo in children with constipation. Compared to all other laxatives, PEG achieved more treatment success, but results on defecation frequency were conflicting. Based on the results of this review, we can give no recommendations to support one laxative over the other for childhood constipation.

Abstract
In the second revision of the practice guideline 'Children with fever' from the Dutch College of General Practitioners, due to its greater reliability rectal measurement of the body temperature above measurement with an ear thermometer is recommended in the case of children younger than 3 months, where the classical signs of infectious diseases are often less apparent. The practice guideline distinguishes between alarm signs which can be recognised by the parents and alarm symptoms which can be diagnosed by the physician during a physical examination. In children younger than 2 years who are feverish with no apparent cause, the urine should be examined at the first consultation. An X-ray of the thorax of a child with fever is only necessary if pneumonia is suspected. As it is not possible at an early stage to identify serious cases among children who are feverish without an apparent cause, these children should be re-examined within 24-48 hours. Children with fever who are younger than 3 months should be referred to a paediatrician. A typical febrile seizure is harmless, nevertheless an underlying meningitis should be excluded.

Abstract
BACKGROUND Adherence is essential for effective treatment. Although several trials on the efficacy of sublingual immunotherapy (SLIT) in youngsters have been published, few contain data on medication intake. OBJECTIVE We aimed to quantify adherence both to study protocol and medication intake as well as to identify factors that may influence adherence to SLIT in youngsters with rhinoconjunctivitis. METHODS Two hundred and four youngsters (6-18 years) with hayfever participated in a randomized controlled trial and used grass pollen extract or placebo for 2 years. The primary outcome of the trial was the mean daily total rhinoconjunctivitis symptom score in the second grass pollen season. Participants having completed the follow-up were considered adherent to the study protocol. Adherence to medication intake was assessed by weighing the study medication. Participants who completed the follow-up and used > or = 80% of the prescribed medication were considered adherent to medication intake. Patient-, disease- and treatment-related factors were analysed. RESULTS One hundred and fifty-four youngsters completed the study. The main reason for discontinuation was the inability to take medication according to schedule. Drop-outs were older, had more difficulty following the medication instructions and their overall evaluation of the treatment effect was lower. The number and reasons for drop-out did not differ between treatment groups. In total, 77% of the participants was adherent to medication intake. Self-reported adherence was 99%. Non-adherent participants experienced more severe symptoms before the trial. Symptom scores did not differ between adherent and non-adherent participants. In adherent as well as non-adherent participants, no difference was found between verum and placebo group with respect to symptom scores. CONCLUSION Adherence to both study protocol and medication intake was good. Drop-out was affected by age, evaluation of the treatment effect and medication instructions. Non-adherence to medication intake was influenced by the severity of the disease before the trial. The ineffectiveness of SLIT could not be explained by non-adherence.

Abstract
OBJECTIVE To determine the construct validity and responsiveness of the Lysholm knee scoring scale and the WOMAC osteoarthritis index in adolescents and young adults with knee complaints in general practice. STUDY DESIGN AND SETTING In the framework of a prospective cohort study with 1-year follow-up, we included 314 patients aged 12-35 years consulting the general practitioner for incident knee complaints. Subgroup analyses of traumatic and nontraumatic knee complaints and of adolescents and adults were performed. RESULTS Construct validity was adequate for both questionnaires both in traumatic and nontraumatic patients (aged 12-35) and in adolescents (12-17) and young adults (18-35). Effect size (ES) and standardized response mean (SRM) for both Lysholm and WOMAC global scores were moderate in nontraumatic patients and high in traumatic patients. Guyatt's responsiveness statistic was high in both subpopulations. Adolescents showed high responsiveness with all measures on the Lysholm scale, and moderate (Guyatt's statistic) to high responsiveness (ES and SRM) on the WOMAC index. Young adults showed high responsiveness with all measures on both instruments. CONCLUSION Although neither of the scales was developed for use in adolescents and young adults in general practice, both scales show adequate responsiveness, content, and construct validity in this population.

Abstract
The practice guideline 'Allergic and non-allergic rhinitis' of the Dutch College ofGeneral Practitioners has been revised based on developments that have occurred in recent years. The most important modifications are: Impermeable covers for beddings are advised only for patients with serious complaints despite the use of medication and other mite-avoidance measures, and patients with allergic rhinitis with asthma. The indication for the use ofa corticosteroid nasal spray is broadened. There is more evidence for the efficacy ofa nasal spray with antihistamines. The indication for cromoglycate has been restricted. Two major unsolved points of discussion concerned the effectiveness of sublingual immunotherapy and the link between asthma and allergic rhinitis.

Abstract
OBJECTIVE To provide an overview of prognostic factors of knee osteoarthritis (OA) progression. METHODS We searched Medline and Embase up to December 2003 according to a specified search strategy (keywords for disease, location, and study design). Studies that fulfilled predefined criteria were assessed for methodologic quality. Study characteristics and associations were extracted and the results were summarized according to a best evidence synthesis. RESULTS Of the 1,004 studies found, 37 met the inclusion criteria. Methodologic quality was assessed and only high-quality studies were included (n = 36). The best evidence synthesis yielded strong evidence that hyaluronic acid serum levels and generalized OA are predictive for progression of knee OA. Sex, knee pain, radiologic severity, knee injury, quadriceps strength, and regular sport activities were not predictive. Conflicting evidence for associations was found for several factors including body mass index and age. Limited evidence for an association with progression of knee OA was found for several factors, including the alignment (varus/valgus) of the joint. Limited evidence for no association with progression of OA was also found for several factors, including meniscectomy, several markers of bone or cartilage turnover, and the clinical diagnosis of localized OA. CONCLUSION Generalized OA and level of hyaluronic acid seem to be associated with the radiologic progression of knee OA. Knee pain, radiologic severity at baseline, sex, quadriceps strength, knee injury, and regular sport activities seem not to be related. For other factors, the evidence was limited or conflicting.

Abstract
The aim of this study was to assess the efficacy of non-pharmacological prophylactic treatments of migraine in children. Databases were searched from inception to June 2004 and references were checked. We selected controlled trials reporting the effects of non-pharmacological prophylactic treatments in children with migraine. We assessed trial quality using the Delphi list and extracted data. Analyses were carried out according to type of intervention. A total of 19 trials were included. Relaxation, relaxation + biofeedback, relaxation + biofeedback + cognitive behavioural treatment were more effective compared with waiting list controls. Relaxation + behavioural therapy was more effective than placebo. There is conflicting evidence for the use of oligoantigenic diets. A few non-pharmacological treatments such as relaxation may be effective as prophylactic treatment for migraine in children. Because of the small number of studies and the methodological shortcomings, conclusions on effectiveness have to be drawn with caution.

Abstract
BACKGROUND Molluscum contagiosum is a common skin infection, caused by a virus, which will usually resolve within months in people with a normal immune system. Many treatments have been promoted for molluscum contagiosum but a clear evidence base supporting them is lacking. OBJECTIVES To assess the effects of management strategies (including waiting for natural resolution) for cutaneous, non-genital molluscum contagiosum in healthy people. SEARCH STRATEGY We searched the Skin Group Specialised Register (March 2004), the Cochrane Central Register of Controlled Trials (2004, Issue 2), MEDLINE (from 1966 to March 2004), EMBASE (from 1980 to March 2004) and LILACS (from 1982 to March 2004) databases. We also searched reference lists and contacted pharmaceutical companies and experts in the field. SELECTION CRITERIA Randomised controlled trials for treatment of molluscum contagiosum were investigated. Trials on sexually transmitted molluscum contagiosum and in people with lowered immunity (including those with HIV infection) were excluded. DATA COLLECTION AND ANALYSIS Study selection and assessment of methodological quality were carried out by two independent authors. As similar comparisons between two interventions were not made in more than one study, statistical pooling was not performed. MAIN RESULTS Five studies, with a total number of 137 participants, examined the effects of topical (three studies), systemic and homoeopathic interventions (one study each). Limited evidence was found for sodium nitrite co-applied with salicylic acid compared to salicylic acid alone (risk ratio (RR) 3.50, 95% confidence interval (CI) 1.23 to 9.92). No statistically significant differences were found for topical povidone iodine plus salicylic acid compared to povidone iodine alone (RR of cure 1.67, 95% CI 0.81 to 3.41) or compared to salicylic acid alone. Also no statistically significant differences were found for potassium hydroxide compared to placebo; systemic treatment with cimetidine versus placebo or systemic treatment with calcarea carbonica, a homoeopathic drug, versus placebo (RR 5.57, 95% CI 0.93 to 33.54). Study limitations included no blinding (two studies), many dropouts (three studies) and no intention-to-treat analysis (two studies); small study sizes may have led to important differences being missed. None of the evaluated treatment options were associated with serious adverse effects. AUTHORS' CONCLUSIONS No single intervention has been shown to be convincingly effective in treating molluscum contagiosum.

Abstract
OBJECTIVE To evaluate the effect of cholecystectomy in patients with gallstones on preoperative abdominal symptoms. METHODS A systematic search was made of the Medline database in combination with reference checking. Articles were excluded if patients aged <18 years, symptom relief rates could not be calculated, if follow-up after cholecystectomy was less than 1 month, or when the included patients were at extraordinary risk for a complicated outcome. Potential differences in relief rates due to patient selection, retrospective versus prospective design, duration of follow-up, or intervention were analyzed using logistic regression. RESULTS The pooled relief rate for "biliary pain" was high 92% (95% confidence interval 86 to 96%). Symptom relief rates were consistently higher in studies that included acute cholecystectomies. For upper abdominal pain--without restrictions for intensity or duration--pooled relief rates ranged from 72% (66 to 77%) after elective cholecystectomy, to 86% (83 to 91%) after acute cholecystectomy. The relief rate of food intolerance was higher in studies with a follow-up < or =12 months (88%, 76 to 91%) compared to studies with a follow-up of more than 12 months (65%, 55 to 74%). CONCLUSION In almost all patients with gallstones biliary pain disappeared after cholecystectomy. There is insufficient evidence, however, that this relief was due to cholecystectomy. Relief rates of other isolated symptoms were low in patients with an elective cholecystectomy. A proper evaluation of the effectiveness of cholecystectomy in terms of abdominal symptom relief rates requires a randomized trial.

Abstract
BACKGROUND Patellofemoral pain syndrome (PFPS) is a common problem among adolescents and young adults, characterised by retropatellar pain (behind the kneecap) or peripatellar pain (around the kneecap) when ascending or descending stairs, squatting or sitting with flexed knees. Etiology, structures causing the pain and treatment methods are all debated in literature, but consensus has not been reached so far. Exercise therapy to strengthen the quadriceps is often prescribed, though its efficacy is still debated. OBJECTIVES This review aims to summarise the evidence of effectiveness of exercise therapy in reducing anterior knee pain and improving knee function in patients with PFPS. SEARCH STRATEGY We searched the Cochrane Musculoskeletal Injuries Group and Cochrane Rehabilitation and Related Therapies Field specialised registers, the Cochrane Controlled Trials Register, PEDro - The Physiotherapy Evidence Database, MEDLINE, EMBASE, CINAHL, up till December 2001 for controlled trials (randomised or not) comparing exercise therapy with control groups, or comparing different types of exercise therapy. SELECTION CRITERIA Only trials focusing on exercise therapy in patients with PFPS were considered. Trials in patients with other diagnoses such as tendinitis, Osgood Schlatter syndrome, bursitis, traumatic injuries, osteoarthritis, plica syndrome, Sinding-Larssen-Johansson syndrome and patellar luxations were excluded. DATA COLLECTION AND ANALYSIS From 750 publications 12 trials were selected. All included trials studied quadriceps strengthening exercises. Outcome assessments for knee pain and knee function in daily life were used in a best evidence synthesis to summarise evidence for effectiveness. MAIN RESULTS One high and two low quality studies used a control group not receiving exercise therapy. Significantly greater pain reduction in the exercise groups was found in one high and one low quality study, though at different time points. Only one low quality study reported significantly greater functional improvement with exercise. Five studies compared exercise therapies that could be designated closed kinetic chain exercise (foot in contact with a surface) versus open kinetic chain exercise (foot not in contact with a surface). Two of these studies were of high quality, but no significant differences in improvement of function or reduction of pain were apparent between the types of exercise in any of the studies. The remaining four studies, all of which were of low quality, focused on other treatment comparisons. REVIEWER'S CONCLUSIONS The evidence that exercise therapy is more effective in treating PFPS than no exercise was limited with respect to pain reduction, and conflicting with respect to functional improvement. There is strong evidence that open and closed kinetic chain exercise are equally effective. Further research to substantiate the efficacy of exercise treatment compared to a non-exercising control group is needed, and thorough consideration should be given to methodological aspects of study design and reporting.

Abstract
BACKGROUND The preferred treatment for stones in the bile duct is endoscopic sphincterotomy followed by stone extraction. When this fails, percutaneous treatment is an alternative to surgery. The purpose of this study was to evaluate the success and complication rate of percutaneous treatment. METHODS Between April 1990 and April 1997, a total of 31 consecutive patients (20 men, 11 women, mean age 70.1 years) underwent percutaneous treatment of bile duct stones (average of 2.2 per patient, range 1 to 10). The percutaneous treatment was considered successful if all stones could be removed. Time and number of sessions needed for imaging, percutaneous treatment, and complications were scored. RESULTS Twenty-seven patients (87%) were free of stones after 2 to 15 sessions (mean 5.6). The median time for treatment was 16 days (3 to 299). Complications occurred in 3 of the 31 patients: one myocardial infarction during extracorporeal shockwave lithotripsy, one pancreatitis, and one bacteremia. None of these complications were life threatening. Four patients (13%) underwent surgery after failed percutaneous treatment. CONCLUSION Percutaneous treatment of bile duct stones is an alternative with a high success rate when endoscopic stone removal fails. Surgery can be avoided in nearly 90% of cases.

Abstract
BACKGROUND Our objective was to evaluate the diagnostic accuracy of abdominal symptoms in gallstones in studies using ultrasonography or oral cholecystography as the reference standard and to assess the extent to which variability in diagnostic accuracy is explained by patient selection and other characteristics of study design. METHODS A Medline search (1966-1998) was conducted in combination with reference checking for further relevant publications. Two independent assessors selected controlled studies that included patients > or =18 years of age. Articles were excluded if sensitivity and specificity could not be extracted or the included patients were at extraordinary risk for gallstones. Seven abdominal symptoms were evaluated. Modification of the diagnostic accuracy by clinical setting, extent of the disease, blinding, age, and sex was analysed by using logistic regression. RESULTS A total of 24 publications were included. The symptoms 'biliary colic', 'radiating pain', and 'analgesics used' were consistently related to gallstones. The setting of the study had a significant effect on the diagnostic accuracy of these symptoms. The unadjusted, pooled diagnostic odds ratios, however, were low (2.6 (95% confidence interval, 2.4-2.9), 2.8 (2.2-3.7), and 2 (1.6-2.5), respectively). The diagnostic odds ratio of biliary colic increased with the extent of gallstone disease (13.3 (4.2-42). CONCLUSIONS Although biliary colic was specific for gallstones, 80% of the referred patients with gallstones presented with other abdominal symptoms. There is no current evidence that justifies the use of single abdominal symptoms, other than biliary colic, in the diagnosis of symptomatic gallstones. Further research should focus on the prognosis of patients with non-specific abdominal symptoms and gallstones.

Abstract
BACKGROUND/AIMS To determine whether sonographic signs of the gallbladder can predict the long-term outcome of laparoscopic cholecystectomy (LC). METHODOLOGY All 346 patients, who underwent LC at our institution between January 1, 1993 and March 1, 1996, were interviewed using a structured questionnaire on the persistence of pre-operative abdominal symptoms. Patients without a sonographic examination 6 months prior to surgery were excluded. Sonographic parameters, scored on the pre-operative examination, were evaluated by univariate analysis using the relief of abdominal symptoms as a dependent variable. RESULTS The response rate of correctly returned questionnaires was 68%. The follow-up ranged from 14-53 months. Fourteen percent (18/133) of all patients reported persistence of abdominal complaints after cholecystectomy. Grit in the gallbladder on the pre-operative ultrasound examination was significantly associated with a higher relative risk (RR) for persistence of pre-operative abdominal symptoms (RR 4.5, 95% confidence intervals (CI) 2.0-10.1). The presence of echogenic bile (RR 1.9, 95% CI 0.8-4.9), gallbladder distention (RR 1.9, 95% CI 0.6-5.7), and gallbladder wall thickening (RR 1.5, 95% CI 0.5-4.1) were associated with the persistence of symptoms. A contracted gallbladder (RR 0.6, 95% CI 0.4-1.1) and stone impaction (RR 0.44, 95% CI 0.1-1.8) were associated with the relief of abdominal symptoms. None of these sonographic signs reached significance. There was no difference in the post-operative symptoms rate between patients with a laparoscopic cholecystectomy and those who were converted to an open cholecystectomy. CONCLUSIONS This retrospective study showed that the sonographic sign of grit in the gallbladder is associated with a high relative risk for persistent abdominal symptoms after cholecystectomy. These findings will be re-evaluated in a prospective study to estimate the definitive clinical importance.

Abstract
BACKGROUND The aim of this study was to determine whether sonographic signs can predict the risk for conversion of laparoscopic (LC) to open cholecystectomy (OC). METHODS All 346 patients who underwent LC at our institution between January 1, 1993, and March 1, 1996, were studied retrospectively. Patients who had no sonographic examination during 6 months prior to surgery and patients treated by inexperienced surgeons were excluded from the study. Patient characteristics and sonographic parameters were evaluated by univariate and multivariate analysis, using conversion to OC as a dependent variable. RESULTS In 23 of 134 patients (17.2%), LC was converted to OC. In the univariate analysis, gallbladder distention (>4.5 cm; relative risk [RR] 3.5; 95% confidence intervals [CI] 1.7-5.3), stone impaction (RR 2.4; 95% CI 1.1-5.1), thickened gallbladder wall (RR 2.4; 95% CI 1.2-5.1), and acute cholecystitis (RR 2.6; 95% CI 1.1-6.7) were able to predict the need for conversion. Logistic regression defined only the sonographic sign of distention of the gallbladder as a predictor of conversion. CONCLUSIONS Gallbladder distention as a sonographic sign is associated with a high relative risk for conversion. The predictive value of sonographic signs for conversion requires further assessment in a prospective study.

Abstract
UNLABELLED Low risk criteria have been defined to identify febrile infants unlikely to have serious bacterial infection (SBI). Using these criteria approximately 40% of all febrile infants can be defined as being at low risk. Of the remaining infants (60%) only 10%-20% have an SBI. No adequate criteria exist to identify these infants. All infants aged 2 weeks-1 year, presenting during a 1-year-period with rectal temperature > or = 38.0 degrees C to the Sophia Children's Hospital were included in a prospective study. Infants with a history of prematurity, perinatal complications, known underlying disease, antibiotic treatment or vaccination during the preceding 48 h were excluded. Clinical and laboratory variables at presentation were evaluated by a multivariate logistic regression model using SBI as the dependent variable. By using likelihood ratios a predictive model was derived, providing a post test probability of SBI for every individual patient. Of the 138 infants included in the study, 33 (24%) had SBI. Logistic regression analysis defined C-reactive protein (CRP), duration of fever, standardized clinical impression score, a history of diarrhoea and focal signs of infection as independent predictors of SBI. CONCLUSION CRP, duration of fever, the "standardized clinical impression score", a history of diarrhoea and focal signs of infection were the independent, most powerful predictors of SBI in febrile infants, identified by logistic regression analysis. Although the predictive model is not validated for direct clinical use, it illustrates the clinical potential of the used technique. This technique offers the advantage of assess the probability of SBI in every individual infant. This probability will form the best basis for well-founded decisions in the management of the individual febrile infant.

The treatment strategies are ESES, in addition to best medical treatment, and best medical treatment alone. Patients are followed-up for at least 18 months. SETTING The ESES-trial is an ongoing multicentre trial in 17 hospitals in The Netherlands. PATIENTS Patients with critical limb ischaemia, nonsuitable for either primary intervention or reintervention after failing reconstructions. CHIEF OUTCOME MEASURES Limb survival, patient survival, quality of life and cost-effectiveness. MAIN RESULTS From November 1991 until May 1994 120 patients had been enrolled. Using life-table analysis, at one year 76% of these randomised patients were alive: 41% without amputation and 35% with amputation. Quality of life of the trial patients was low, even compared to other severely ill patient groups, such as liver and heart transplant candidates. CONCLUSIONS Considering the high incidence of death and amputation, 18 months of follow-up seems adequate to detect a clinically relevant outcome improvement from ESES-treatment, if present. We hope to present the results of this study at the end of 1995.

Abstract
Shortly after extracorporeal shock wave lithotripsy (ESWL) was introduced as a promising new treatment modality for gallstone disease, a randomized controlled study was performed to assess the cost-effectiveness of ESWL compared to open cholecystectomy, the gold standard. During the performance of this study it was found that during a 3-year intake period only 8.3% (37 of 448) of the patients could be entered into the trial. Three factors were identified that hampered patient accrual: (1) restricted eligibility for ESWL (and thus for the study), which could not have been predicted on the data provided in the literature; (2) the introduction of laparoscopic cholecystectomy; and (3) strong patient preference, inhibiting randomization. All three mechanisms could not have been predicted during the design phase of the study. It is concluded that it is not always feasible to conduct a randomized study in surgery due to unforeseen circumstances. Entering patients into surgical trials is difficult in quickly evolving fields of surgery, such as the management of gallstone disease. Acquiring informed consent is also difficult when treatment characteristics are divergent. A randomized controlled study on the effects of laparoscopic cholecystectomy will therefore probably never be performed.

Abstract
To determine the value of a detailed family history for the assessment of the risk of recurrence of febrile seizures, 115 children who visited the emergency room of an academic children's hospital were studied prospectively. The recurrence risk of febrile seizures was analysed in relation to the child's family history and the proportion of relatives affected by febrile seizures using Kaplan-Meier estimates and Cox proportional hazard models. A first degree family history positive for febrile seizures (parents or siblings affected by febrile seizures) increased a child's two year recurrence risk from 27 to 52%. No significant increase of recurrence risk for febrile seizures was found in children with second degree relatives (grandparents and uncles/aunts) or cousins only affected by febrile seizures. Recurrence risk was significantly correlated with the proportion of first degree relatives affected by febrile seizures: risks were 27, 40, and 83% in children whose proportion was 0, 0-0.5, and > or = 0.5 respectively. Analysis of the recurrence risk in relation to a weighted proportion, adjusted for the attained age and sex of first degree relatives, showed similar results. It is concluded that the application of the proportion of first degree relatives affected by febrile seizures generates a more differentiated assessment of the recurrence risk of febrile seizures.

Abstract
BACKGROUND Distant metastasis in carcinoma of the esophagus and gastroesophageal junction is associated with a poor survival after resection. To improve the selection of patients for surgical and nonsurgical treatment, this study determined the influence on survival of distant metastases, as assessed on radiologic studies or proven on cytologic studies. METHODS During the period 1989-1990, 135 patients were referred to the institution in this study. On ultrasonographic or computed tomographic studies, distant metastases were suspected in 62 patients and were absent in 73 patients. In 33 patients, metastases were proven cytologically; 32 of these patients subsequently were excluded from surgery. Twelve other patients were unfit for surgery because of their general condition. The remaining 91 patients had surgery; 77 patients had transhiatal esophagectomy, and the tumor was unresectable in 14 patients. RESULTS The 2-year survival rate for all patients in whom distant metastases were suspected on radiologic studies was 11.2%, and it was 44.3% for patients without metastases on these studies (P < 0.001). For patients with cytologically proven metastases, the 2-year survival rate (3%) was lower than for patients in whom distant metastases were suspected on radiologic studies but not cytologically confirmed (21.1%) (P < 0.001). There was no statistically significant difference in survival between this last group of patients and those without metastases identified by radiologic studies (P = 0.87). After resection, the 2-year survival rate decreased from 53.9% to 0% when distant metastases were present on histopathologic studies of the resected specimen (P = 0.04), and there was no significant difference in survival between patients with distant metastases suspected or absent on preoperative radiologic studies (P = 0.47). CONCLUSIONS Surgery should be avoided in patients with cytologically proven distant metastases because the expected survival rate is low and surgery does not seem to be a life-prolonging procedure in these patients; however, patients should not be excluded from surgery on the basis of metastases identified by radiologic studies alone.

Abstract
The ability of preoperative CT to assess resectability and to stage carcinoma of the esophagus and gastroesophageal junction was studied in 71 patients who underwent transhiatal esophagectomy. Patients with preoperatively proven distant metastases who did not have surgery were not included in the present study. At surgery the tumor invaded adjacent mediastinal or abdominal structures in 18 patients (prevalence 25%), but was nonresectable in only 7 of these 18 patients (39%). Invasions of the tracheobronchial tree, the aorta, and the diaphragm were correctly detected on CT in 5 of 6, 1 of 2, and 2 of 10 patients. There were four false-positive results on CT; tracheobronchial invasion and pericardial invasion were incorrectly predicted in one and three patients, respectively. Invasion of adjacent structures was correctly assessed on CT in 58 (82%) patients and the depth of tumor invasion was correctly determined in 49 (69%) patients. Computed tomography correctly staged 57% of patients according to the classification of the American Joint Committee on Cancer. Understaging (31%) occurred more often than overstaging (11%). In the present study, computed tomography was not effective in assessing non-resectability by diagnosing invasion because of the relatively low prevalence of invasion of adjacent structures and the fact that invasion was often not associated with nonresectability. In assessing invasion itself, CT was accurate in diagnosing tracheobronchial involvement, but was limited in diagnosing invasion of other adjacent structures. In assessing stage grouping, CT was limited in detecting either diaphragmatic invasion or lymph node involvement.

Abstract
The purpose of the study was to evaluate ultrasound and computed tomography in the assessment of distant metastases, supraclavicular and abdominal, in 113 patients with carcinoma of the oesophagus and gastrooesophageal junction. Ultrasound and computed tomographic findings were compared with the cytological data in 29 patients and with the surgical data in 84 patients. In assessing distant metastases, ultrasound and computed tomography had a sensitivity of 61% and 70%, and a specificity of 93% and 85%, respectively (p = 1.0). When ultrasound and computed tomography were combined the sensitivity increased to 83% and the specificity decreased to 81%. There was no significant difference in the assessment of supraclavicular metastases (p = 0.8), coeliac metastases (p = 1.0) or liver and other non-lymphatic abdominal metastases (p = 1.0) on ultrasound or computed tomography. The results show that both ultrasound and computed tomography should be used for assessment of distant metastases and abnormalities confirmed by image-guided biopsy.

Abstract
The use of ultrasound (US)-guided fine-needle aspiration biopsy (FNAB) for the assessment of distant metastases was prospectively studied in 135 consecutive patients with carcinoma of the esophagus and gastroesophageal junction. Patients with accessible lesions on US and computed tomographic (CT) studies of the supraclavicular regions and the abdomen underwent US-guided FNAB. In patients with multiple lesions biopsies were preferentially performed on enlarged supraclavicular nodes. Forty-nine patients underwent US-guided FNABs of 53 lesions. A cytologic diagnosis was established in 46 of 53 (87%) biopsies. Seven of 53 (13%) biopsies were nondiagnostic. Distant metastases were diagnosed by means of cytologic study in 33 of 135 (24%) patients. Supraclavicular metastases were diagnosed in 22 patients and abdominal metastases were diagnosed in 12 patients, including one patient who also had supraclavicular metastases. US-guided FNAB can improve the selection of patients for surgical and nonsurgical treatment by diagnosing distant metastases in an important number of patients.

Abstract
The preoperative assessment of supraclavicular lymph node metastases was prospectively studied in 100 patients with carcinoma of the esophagus and gastroesophageal junction. Findings at computed tomography (CT), ultrasound (US), and palpation were compared, and US-guided fine-needle aspiration biopsy of nodes with a small axis of 5 mm or greater was performed. Supraclavicular metastases were detected on CT scans in 11 of 13 patients (85%) and on US scans in 14 of 16 patients (88%) but were palpable in only three of the 16 patients (19%). The predictive value of a supraclavicular node indicating metastases was .74 at US and .85 at CT. Metastases were diagnosed in 10 of 46 patients with squamous cell carcinoma (22%) and five of 50 patients (10%) with adenocarcinoma. Nodes with metastases had a round configuration, with a statistically significant greater short-axis to long-axis ratio than that of benign nodes (0.89 vs 0.54; P = .05). In four of 16 patients (25%) with supraclavicular metastases proved with cytologic examination, neither CT nor US of the mediastinum and abdomen showed enlarged nodes.
