Effect of pelvic floor muscle training compared with watchful waiting in older women with symptomatic mild pelvic organ prolapse : randomised controlled trial in primary care

Objective To compare the effects of pelvic floor muscle training and watchful waiting on pelvic floor symptoms in a primary care population of women aged 55 years and over with symptomatic mild pelvic organ prolapse. Design Randomised controlled trial. Setting Dutch primary care. Participants Women aged 55 years or over with symptomatic mild prolapse (leading edge above the hymen) were identified by screening. Exclusion criteria were current prolapse treatment or treatment in the previous year, malignancy of pelvic organs, current treatment for another gynaecological disorder, severe/terminal illness, impaired mobility, cognitive impairment, and insufficient command of the Dutch language. Interventions Pelvic floor muscle training versus watchful waiting. Main outcome measures The primary outcome was change in bladder, bowel, and pelvic floor symptoms measured with the Pelvic Floor Distress Inventory-20 (PFDI-20), three months after the start of treatment. Secondary outcomes were changes in condition specific and general quality of life, sexual function, degree of prolapse, pelvic floor muscle function, and patients’ perceived change in symptoms. Results Of the 287 women who were randomised to pelvic floor muscle training (n=145) or watchful waiting (n=142), 250 (87%) completed follow-up. Participants in the intervention group improved by (on average) 9.1 (95% confidence interval 2.8 to 15.4) points more on the PFDI-20 than did participants in the watchful waiting group (P=0.005). Of women in the pelvic floor muscle training group, 57% (82/145) reported an improvement in overall symptoms from the start of the study compared with 13% (18/142) in the watchful waiting group (P<0.001). Other secondary outcomes showed no significant difference between the groups. Conclusions Although pelvic floor muscle training led to a significantly greater improvement in PFDI-20 score, the difference between the groups was below the presumed level of clinical relevance (15 points). Nevertheless, 57% of the participants in the intervention group reported an improvement of overall symptoms. More studies are needed to identify factors related to success of pelvic floor muscle training and to investigate long term effects.

Childhood Nonspecific Abdominal Pain in Family Practice: Incidence, Associated Factors, and Management

PURPOSE Nonspecific abdominal pain (NSAP) is a common complaint in childhood. In specialist care, childhood NSAP is considered to be a complex and time-consuming problem, and parents are hard to reassure. Little is known about NSAP in family practice, but the impression is that family physicians consider it to be a benign syndrome needing little more than reassurance. This discrepancy calls for a better understanding of NSAP in family practice. METHODS Data were obtained from the Second Dutch National Survey of General Practice (2001). Using registration data of 91 family practices, we identified children aged 4 to 17 years with NSAP. We calculated the incidence, and we studied factors associated with childhood NSAP, referrals, and prescriptions. RESULTS The incidence of NSAP was 25.0 (95% confidence interval [CI], 23.7–26.3) per 1,000 person years. Most children (92.7%) with newly diagnosed NSAP (N = 1,480) consulted their doctor for this condition once or twice. Factors independently associated with NSAP were female sex (odds ratio [OR] = 1.4; 95% CI, 1.3–1.5), nongastrointestinal-nonspecific somatic symptoms (OR = 1.3; 95% CI, 1.1–1.5), and health care use (OR = 1.04; 95% CI, 1.03–1.05). When NSAP was diagnosed at the first visit, 3% of the patients were referred to specialist care, and 1% received additional testing. Family physicians prescribed medication in 21.3% of the visits for NSAP. CONCLUSIONS Childhood NSAP is a common problem in family practice. Most patients visit their doctor once or twice for this problem. Family physicians use little additional testing and make few referrals in their management of childhood NSAP. Despite the lack of evidence for effectiveness, family physicians commonly prescribe medication for NSAP.

Noninvasive Tests for Inflammatory Bowel Disease: A Meta-analysis

BACKGROUND: The clinical presentation of pediatric inflammatory bowel disease (IBD) is often nonspecific and overlaps with functional gastrointestinal disorders. OBJECTIVE: To determine the diagnostic accuracy of symptoms, signs, noninvasive tests, and test combinations that can assist the clinician with the diagnosis of IBD in symptomatic children. METHODS: A literature search was conducted of Medline and Embase. Two reviewers independently selected studies reporting on the diagnostic accuracy of tests for IBD, with confirmation by endoscopy and histopathology or clinical follow-up, in children with chronic gastrointestinal symptoms. Two reviewers independently extracted data and assessed study quality with the QUADAS-2, an evidence-based quality assessment tool for diagnostic accuracy studies. RESULTS: Nineteen studies were included (N = 2806). Symptoms (abdominal pain, diarrhea, rectal bleeding, and weight loss) had pooled sensitivities ranging from 0.48 to 0.82 and specificities ranging from 0.17 to 0.78. Of all the blood markers, C-reactive protein (CRP) (9 studies) and albumin (6 studies) had the best performance, with pooled sensitivities of 0.63 (0.51–0.73) and 0.48 (0.31–0.66), respectively, and specificities of 0.88 (0.80–0.93) and 0.94 (0.86–0.98). Assessment of fecal calprotectin (FCal) (10 studies) had a pooled sensitivity of 0.99 (0.92–1.00) and a specificity of 0.65 (0.54–0.74). One limitation was that none of the studies was conducted in nonreferred children. CONCLUSIONS: In children whose pediatrician is considering an endoscopy, symptoms are not accurate enough to identify low-risk patients in whom an endoscopy can be avoided. FCal, CRP, and albumin findings are potentially of clinical value, given their ability to select children at low risk (negative FCal test result) or high risk (positive CRP or albumin test result) for IBD.

Prognostic factors for persistence of chronic abdominal pain in children

Objectives: The aim of the study was to identify prognostic factors for the persistence of chronic abdominal pain (CAP) in children. Materials and Methods: For this systematic review, MEDLINE, EMBASE, and PsycINFO were searched up to June 2008 for prospective follow-up studies of pediatric CAP as defined by the criteria of Apley, von Baeyer, or the Rome committee. The outcome measure of interest was persistence of CAP. Persistent CAP was considered only when the abdominal pain of children with CAP persisted during follow-up at the same level of frequency and severity. For each study the risk for bias was assessed. The evidence for prognostic factors was summarized according to a best-evidence synthesis. Results: Eight studies, which examined 17 prognostic factors, were included. Moderate evidence was found that having a parent with gastrointestinal symptoms predicts the persistence of CAP. Strong evidence was found for no association between female sex and the duration of CAP, and moderate evidence that the severity of abdominal pain does not predict persistence of CAP. There is conflicting evidence as to whether psychological factors prevent, or have no relation with, persistence of CAP. Conclusions: Because there are few prognostic follow-up studies on pediatric CAP, the evidence for prognostic factors is limited. Physicians should ask about parental gastrointestinal problems because this is a risk factor for persistence of CAP in children. The hypothesis that psychological factors of the child predict persistence of CAP is not supported by evidence from the follow-up studies.

Prevalence, characteristics, and management of childhood functional abdominal pain in general practice

Abstract Objective. To (i) describe the proportion of children presenting with abdominal pain diagnosed by the GP as functional abdominal pain (GPFAP); (ii) evaluate the association between patient and disease characteristics and GPFAP; (iii) describe diagnostic management by the GP in children presenting with abdominal pain, and (iv) evaluate whether children with GPFAP fulfill diagnostic criteria for functional abdominal pain (FAP) as described in current literature: chronic abdominal pain (CAP) and the Rome III criteria (PRC-III) for abdominal pain-related functional gastrointestinal disorders (FGID). Design. Cross-sectional study. Setting. General practices in the Netherlands. Subjects. 305 children aged 4–17 years consulting for abdominal pain. Main outcome measures. GPFAP, CAP, FGIDs. Results. 89.2% of children were diagnosed with GPFAP. Headaches and bloating were positively associated with GPFAP whereas fever and > 3 red flag symptoms were inversely associated. Additional diagnostic tests were performed in 26.8% of children. Less than 50% of all children with GPFAP fulfilled criteria for CAP and FGIDs; in 47.9% of patients the duration of symptoms at presentation was less than three months. Conclusions. In almost 90% of children included in this study the GP suspected no organic cause for the abdominal pain. GPs diagnose FAP in children without alarm symptoms and order diagnostic testing in one out of four children presenting with abdominal pain. No difference was found in GPs’ management between children with a diagnosis of GPFAP and other diagnoses. Only about half of the children with a GP diagnosis of FAP fulfilled time-criteria of FAP as defined in the literature.

Prognosis of Abdominal Pain in Children in Primary Care—A Prospective Cohort Study

PURPOSE Abdominal pain is a common complaint in children. Because few data exist on its natural history, we wanted to investigate the prognosis of abdominal pain in children in general practice. METHODS In a prospective cohort study of children (aged 4 to 17 years) complaining of abdominal pain, follow-up was at 3, 6, 9, and 12 months using standardized questionnaires. The primary outcome measure was chronic abdominal pain: abdominal pain at least 1 time a month during at least 3 consecutive months that had an impact on daily activities. Prevalence, incidence, and duration of chronic abdominal pain were assessed. RESULTS Three hundred five children (116 boys, 189 girls), with a median age of 7.8 years (interquartile range [IQR] = 5.7–10.5 years) were included. Chronic abdominal pain was present in 142 (46.6%) children at an initial visit to the primary care physician for this complaint. During follow-up, 78.7% fulfilled the criteria for chronic abdominal pain at 1 or more follow-up points. Among 163 children at risk for developing chronic abdominal pain, the cumulative incidence of chronic abdominal pain was 60.1% (95% CI, 52.1%–67.7%) and was higher in girls than in boys (RR = 1.23; 95% CI, 0.94–1.61). Median duration of abdominal pain was 7.5 months (IQR = 4.5–12.0 months). Children aged 10 to 17 years had the longest duration of abdominal pain (median = 9.0 months; IQR = 7.5–12.4 months). Children with symptoms of irritable bowel syndrome seemed to have a less favorable prognosis compared with children with symptoms of functional dyspepsia or functional abdominal pain. CONCLUSIONS The presence and development of chronic abdominal pain is common and of long duration among children consulting in primary care for abdominal pain. These poor outcome data warrant follow-up.

The course of mental health problems in children presenting with abdominal pain in general practice

Abstract Objective. To investigate the course of mental health problems in children presenting to general practice with abdominal pain and to evaluate the extent to which abdominal pain characteristics during follow-up predict the presence of mental health problems at 12 months’ follow-up. Design. A prospective cohort study with one-year follow-up. Setting. 53 general practices in the Netherlands, between May 2004 and March 2006. Subjects. 281 children aged 4–17 years. Main outcome measures. The presence of a depressive problem, an anxiety problem, and multiple non-specific somatic symptoms at follow-up and odds ratios of duration, frequency, and severity of abdominal pain with these mental health problems at follow-up. Results. A depressive problem persisted in 24/74 children (32.9%; 95% CI 22.3–44.9%), an anxiety problem in 13/43 (30.2%; 95% CI 17.2–46.1%) and the presence of multiple non-specific somatic symptoms in 75/170 children (44.1%; 95% CI 36.7–51.6%). None of the abdominal pain characteristics predicted a depressive or an anxiety problem at 12 months’ follow-up. More moments of moderate to severe abdominal pain predicted the presence of multiple non-specific somatic symptoms at follow-up. Conclusions. In one-third of the children presenting to general practice for abdominal pain, anxiety and depressive problems persist during one year of follow-up. Characteristics of the abdominal pain during the follow-up period do not predict anxiety or depressive problems after one-year follow-up. We recommend following over time children seen in primary care with abdominal pain.

No evidence for systemic platelet activation during or after orthotopic liver transplantation.

Platelet function is thought to deteriorate during liver transplantation as a result of platelet activation and proteolysis of platelet receptors by plasmin following reperfusion. However, this hypothesis has never been formally tested. Twenty patients undergoing a first or second liver transplant were included in the study. Blood samples were taken at standardized time points during transplantation and up to 10 days after transplantation. Platelet activation was assessed by detection of the activation markers P‐selectin and activated integrin αIIbβ3 with flow cytometry. Proteolytic cleavage of platelet receptors was assessed by flow cytometry measurement of the constitutively expressed platelet receptors glycoprotein Ibα and integrin αIIbβ3. In addition, using enzyme‐linked immunosorbent assay techniques, we measured plasma levels of platelet activation products β‐thromboglobulin and platelet factor 4 and plasma levels of cleaved fragments of glycoproteins Ibα and V. Flow cytometry analyses provided no evidence of substantial platelet activation during transplantation. In fact, the expression of activated integrin αIIbβ3 decreased postoperatively; this indicated that platelets were in a slightly activated state prior to surgery. Plasma levels of β‐thromboglobulin and platelet factor 4 also substantially decreased after transplantation. In addition, no changes were observed in the constitutively expressed platelet receptors or in the plasma levels of platelet receptor fragments, and this indicated a lack of substantial receptor proteolysis. In conclusion, no evidence was found for significant activation of circulating blood platelets or the proteolysis of key platelet receptors during liver transplantation. These findings suggest that the platelet functional capacity does not decrease during liver transplantation. Liver Transpl 15:956–962, 2009.

Sexual function in older women with pelvic floor symptoms: a cross-sectional study in general practice.

BACKGROUND Pelvic floor symptoms are common and are negatively associated with sexual function which, in turn, is an important aspect of quality of life. The majority of older women with pelvic floor symptoms are treated in general practice but evidence from studies in general practice on the sexual functioning of these women is scarce. AIM This study examined predictors of sexual inactivity in older women with pelvic floor symptoms in general practice and of sexual functioning in those women who are sexually active. DESIGN AND SETTING Cross-sectional study in women (aged ≥55 years) from 20 general practices who screened positive on a pelvic floor symptom questionnaire. METHOD Logistic and linear regression analyses were used to determine predictors of sexual inactivity and sexual functioning (PISQ-12) by assessing their association with patient characteristics, symptoms (PFDI-20) and degree of prolapse (POP-Q). RESULTS A total of 639 women were included (sexually active n = 393, sexually inactive n = 246). Predictors of sexual inactivity were increasing age (odds ratio [OR] = 1.13; 95% confidence interval [CI] = 1.10 to 1.17) and lower education (OR = 2.31; 95% CI = 1.50 to 3.54; Nagelkerke R(2) = 0.208). In sexually active women, sexual functioning was associated with pelvic floor symptom distress (P<0.001) and pelvic floor surgery (P = 0.018; R(2) = 0.138). CONCLUSION In older women with pelvic floor symptoms, increasing age and lower educational level are predictors of sexual inactivity. Many of these older women are sexually active and pelvic floor symptom distress is negatively associated with sexual functioning. These results may encourage GPs to ask about sexual problems in women with pelvic floor symptoms.

Avoid Endoscopy in Children With Suspected Inflammatory Bowel Disease Who Have Normal Calprotectin Levels

ABSTRACT In children with suspected inflammatory bowel disease, adding calprotectin stool testing to the screening strategy has been recommended to distinguish organic from nonorganic disease. In this cohort study with historical controls, we could not confirm that screening with stool calprotectin improves the diagnostic yield (ratio inflammatory bowel disease–positive endoscopies and total number of endoscopies); however, in patients with normal fecal calprotectin levels (<50 &mgr;g/g) endoscopic and histological abnormalities were not seen. We propose to refrain from endoscopy when stool calprotectin levels are normal.
