Pain Among Children and Adolescents: Restrictions in Daily Living and Triggering Factors

Abstract: Objectives. Pain among children and adolescents has been identified as an important public health problem. Most studies evaluating recurrent or chronic pain conditions among children have been limited to descriptions of pain intensity and duration. The effects of pain states and their impact on daily living have rarely been studied. The objective of this study was to investigate the impact of perceived pain on the daily lives and activities of children and adolescents. In addition, we sought to delineate self-perceived triggers of pain among children and adolescents. In this study, we (1) document the 3-month prevalence of painful conditions among children and adolescents, (2) delineate their features (location, intensity, frequency, and duration), (3) describe their consequences (restrictions and health care utilization), and (4) elucidate factors that contribute to the occurrence of pain episodes among young subjects. Methods. The study was conducted in 1 elementary school and 2 secondary schools in the district of Ostholstein, Germany. Children and adolescents, as well as their parents/guardians, were contacted through their school administrators. The teachers distributed an information leaflet, explaining the conduct and aim of the study, to the parents a few days before the official enrollment of the youths in the study. Parents of children in grades 1 to 4 of elementary school were asked to complete the pain questionnaire for their children at home, whereas children from grade 5 upward completed the questionnaire on their own during class, under the supervision of their teachers. The response rate was 80.3%. As previously stated, chronic pain was defined as any prolonged pain that lasted a minimum of 3 months or any pain that recurred throughout a minimal period of 3 months. The children and adolescents were surveyed with the Luebeck Pain-Screening Questionnaire, which was specifically designed for an epidemiologic study of the characteristics and consequences of pain among children and adolescents. The questionnaire evaluates the prevalence of pain in the preceding 3 months. The body area, frequency, intensity, and duration of pain are addressed by the questionnaire. In addition, the questionnaire inquires about the private and public consequences of pain among young subjects. Specifically, the questionnaire aims to delineate the self-perceived factors for the development and maintenance of pain and the impact of these conditions on daily life. Results. Of the 749 children and adolescents, 622 (83%) had experienced pain during the preceding 3 months. A total of 30.8% of the children and adolescents stated that the pain had been present for >6 months. Headache (60.5%), abdominal pain (43.3%), limb pain (33.6%), and back pain (30.2) were the most prevalent pain types among the respondents. Children and adolescents with pain reported that their pain caused the following sequelae: sleep problems (53.6%), inability to pursue hobbies (53.3%), eating problems (51.1%), school absence (48.8%), and inability to meet friends (46.7%). The prevalence of restrictions in daily living attributable to pain increased with age. A total of 50.9% of children and adolescents with pain sought professional help for their conditions, and 51.5% reported the use of pain medications. The prevalence of doctor visits and medication use increased with age. Weather conditions (33%), illness (30.7%), and physical exertion (21.9%) were the most frequent self-perceived triggers for pain noted by the respondents. A total of 30.4% of study participants registered headache as the most bothersome pain, whereas 12.3% cited abdominal pain, 10.7% pain in the extremities, 8.9% back pain, and 3.9% sore throat as being most bothersome. A total of 35.2% of children and adolescents reported pain episodes occurring ≥1 time per week or even more often. Health care utilization because of pain differed among children and adolescents according to the location of pain. Children and adolescents with back pain (56.7%), limb pain (55.0%), and abdominal pain (53.3%) visited a doctor more often than did those with headache (32.5%). In contrast, children and adolescents with headache (59.2%) reported taking medication because of pain more often than did those with back pain (16.4%), limb pain (22.5%), and abdominal pain (38.0%). The prevalence of self-reported medication use and doctor visits because of pain increased significantly with age (χ 2 test). The prevalence of self-reported medication use was significantly higher among girls than among boys of the same age, except between the ages of 4 and 9 years (χ 2 test). The prevalence of restrictions in daily activities varied among children and adolescents with different pain locations; 51.1% of children and adolescents with abdominal pain and 43.0% with headache but only 19.4% with back pain reported having been absent from school because of pain. The prevalence of restrictions attributable to pain was significantly higher among girls than among boys of the same age, except between the ages of 4 and 9 years (χ 2 test). The self-reported triggers for pain varied between girls and boys. Girls stated more often than boys that their pain was triggered by weather conditions (39% vs 25%), illness (eg, common cold or injury) (35.9% vs 23.9%), anger/disputes (20.9% vs 11.9%), family conditions (12.1% vs 5.2%), and sadness (11.9% vs 3.4%). In contrast, boys stated more often than girls that their pain was triggered by physical exertion (28% vs 17.2%). We used a logistic regression model to predict the likelihood of a child paying a visit to the doctor and/or using pain medication. Health care utilization was predicted by increasing age, greater intensity of pain, and longer duration of pain but not by the frequency of pain. We used a logistic regression model to predict restrictions in daily activities. Only the intensity of pain was predictive of the degree of restrictions in daily life attributable to pain; the duration of pain and the frequency of pain episodes had no bearing on the degree to which the daily lives of the children were restricted because of pain. Conclusions. More than two thirds of the respondents reported restrictions in daily living activities attributable to pain. However, 30 to 40% of children and adolescents with pain reported moderate effects of their pain on school attendance, participation in hobbies, maintenance of social contacts, appetite, and sleep, as well as increased utilization of health services because of their pain. Restrictions in daily activities in general and health care utilization because of pain increased with age. Girls ≥10 years of age reported more restrictions in daily living and used more medications for their pain than did boys of the same age. We found gender-specific differences in self-perceived triggers for pain. Pain intensity was the most robust variable for predicting functional impairment in ≥1 areas of daily life. Increasing age of the child and increasing intensity and duration of pain had effects in predicting health care utilization (visiting a doctor and/or taking medication), whereas restrictions in daily activities were predicted only by the intensity of pain. Our results underscore the relevance of pediatric pain for public health policy. Additional studies are necessary and may enhance our knowledge about pediatric pain, to enable parents, teachers, and health care professionals to assist young people with pain management, allowing the young people to intervene positively in their conditions before they become recurrent or persistent.

Irritable bowel syndrome in the United States: prevalence, symptom patterns and impact.

Abstract: Summary Background : The impact of irritable bowel syndrome, a gastrointestinal motility disorder, is underestimated and poorly quantified, as clinicians may see only a minority of sufferers. Aim : To determine the prevalence, symptom patterns and impact of irritable bowel syndrome in the US. Methods : This two-phase community survey used quota sampling and random-digit telephone dialling (screening interview) to identify individuals with medically diagnosed irritable bowel syndrome or individuals not formally diagnosed, but fulfilling irritable bowel syndrome diagnostic criteria (Manning, Rome I or II). Information on irritable bowel syndrome symptoms, general health status, lifestyle and impact of symptoms on individuals’ lives was collected using in-depth follow-up interviews. Data were also collected for healthy controls identified in the screening interviews. Results : The total prevalence of irritable bowel syndrome in 5009 screening interviews was 14.1% (medically diagnosed: 3.3%; undiagnosed, but meeting irritable bowel syndrome criteria: 10.8%). Abdominal pain/discomfort was the most common symptom prompting consultation. Most sufferers (74% medically diagnosed; 63% undiagnosed) reported alternating constipation and diarrhoea. Previously diagnosed gastrointestinal disorders occurred more often in sufferers than non-sufferers. Irritable bowel syndrome sufferers had more days off work (6.4 vs. 3.0) and days in bed, and reduced activities to a greater extent than non-sufferers. Conclusions : Most (76.6%) irritable bowel syndrome sufferers in the US are undiagnosed. Irritable bowel syndrome has a substantial impact on sufferers’ well-being and health, with considerable socioeconomic consequences.

Median Arcuate Ligament Syndrome: Evaluation with CT Angiography

Abstract: The median arcuate ligament is a fibrous arch that unites the diaphragmatic crura on either side of the aortic hiatus. The ligament usually passes superior to the origin of the celiac axis. However, in some people, the ligament inserts low and thus crosses the proximal portion of the celiac axis, causing compression and sometimes resulting in abdominal pain. The diagnosis of clinically significant celiac axis compression, referred to as median arcuate ligament syndrome, is traditionally made with conventional angiography; however, the condition can now be diagnosed with three-dimensional computed tomographic (CT) angiography. In patients with median arcuate ligament syndrome, CT angiograms demonstrate a characteristic focal narrowing in the proximal celiac axis. The focal narrowing has a characteristic hooked appearance, which can help distinguish this condition from other causes of celiac artery narrowing, such as atherosclerotic disease. Once the disorder has been diagnosed, surgery can be performed to ...

Randomized controlled trial of appendicectomy versus antibiotic therapy for acute appendicitis

Abstract: In a prospective controlled study the effect of antibiotics as the only treatment in acute appendicitis was evaluated. Of 40 patients admitted with a duration of abdominal pain of less than 72 h, 20 received antibiotics intravenously for 2 days followed by oral treatment for 8 days and 20 considered as controls were randomized to surgery. All patients treated conservatively were discharged within 2 days, except one who required surgery after 12 h because of peritonitis secondary to perforated appendicitis. Seven patients were readmitted within 1 year as a result of recurrent appendicitis and underwent surgery, when appendicitis was confirmed. The diagnostic accuracy within the operated group was 85 per cent. One patient had perforated appendicitis at operation. Antibiotic treatment in patients with acute appendicitis was as effective as surgery. The patients had less pain and required less analgesia, but the recurrence rate was high.

Clinical features of colorectal cancer before diagnosis: a population-based case–control study

Abstract: Most colorectal cancers are diagnosed after the onset of symptoms. However, the risk of colorectal cancer posed by particular symptoms is largely unknown, especially in unselected populations like primary care. This was a population-based case–control study in all 21 general practices in Exeter, Devon, UK, aiming to identify and quantify the prediagnostic features of colorectal cancer. In total, 349 patients with colorectal cancer, aged 40 years or more, and 1744 controls, matched by age, sex and general practice, were studied. The full medical record for 2 years before diagnosis was coded using the International Classification of Primary Care-2. We calculated odds ratios for variables independently associated with cancer, using multivariable conditional logistic regressions, and then calculated the positive predictive values of these variables, both individually and in combination. In total, 10 features were associated with colorectal cancer before diagnosis. The positive predictive values (95% confidence interval) of these were rectal bleeding 2.4% (1.9, 3.2); weight loss 1.2% (0.91, 1.6); abdominal pain 1.1% (0.86, 1.3); diarrhoea 0.94% (0.73, 1.1); constipation 0.42% (0.34, 0.52); abnormal rectal examination 4.0% (2.4, 7.4); abdominal tenderness 1.1% (0.77, 1.5); haemoglobin 10 mmol l−1 0.78% (0.51, 1.1): all P<0.001. Earlier diagnosis of colorectal cancer may be possible using the predictive values for single or multiple symptoms, physical signs or test results.

A controlled crossover study of the selective serotonin reuptake inhibitor citalopram in irritable bowel syndrome

Abstract: Introduction: Selective serotonin reuptake inhibitors (SSRIs) are frequently used in the treatment of irritable bowel syndrome (IBS) although evidence of their efficacy is scarce. Aim: Twenty three non-depressed IBS patients were recruited from a tertiary care centre and included in a crossover trial comparing six weeks of treatment with the SSRI citalopram (20 mg for three weeks, 40 mg for three weeks) with placebo. IBS symptom severity was the primary outcome measure, and depression and anxiety scores were also measured. The effect of acute administration of citalopram on colonic sensitivity and on colonic response to feeding was investigated as a putative predictor of symptomatic response to the drug. Results: After three and six weeks of treatment, citalopram significantly improved abdominal pain, bloating, impact of symptoms on daily life, and overall well being compared with placebo. There was only a modest effect on stool pattern. Changes in depression or anxiety scores were not related to symptom improvement. The effect of acute administration of citalopram during a colonic barostat study did not predict clinical outcome. Analysis of the first treatment period as a double blind parallel arm study confirmed the benefit of citalopram over placebo. Conclusions: The SSRI citalopram significantly improves IBS symptoms, including abdominal pain, compared with placebo. The therapeutic effect is independent of effects on anxiety, depression, and colonic sensorimotor function.

Relationship of pain and symptoms to pubertal development in adolescents

Abstract: Temporomandibular disorder (TMD) pain, abdominal pain, migraine and tension-type headache are more prevalent in women than in men. This study assessed the relationship of back pain, headache, abdominal pain, TMD pain, and the presence of multiple pain conditions to gender and pubertal development in a cross-sectional, population-based survey of adolescents. We also examined the association between pubertal development and depressive and somatic symptoms, factors often associated with pain in adults. We hypothesized that prevalence of all pain conditions, as well as rates of other symptoms, would increase as puberty progresses in females, but not males. Subjects (3,101 boys and girls, 11-17 years old, selected from an HMO population) reported on the presence of each pain condition in the prior 3 months and completed scales assessing pubertal development, and depressive and somatic symptoms. Data were analyzed using descriptive statistics and multivariate logistic regression. Prevalence rates were weighted for factors affecting response. Prevalence of back pain, headache and TMD pain increased significantly (odds ratios, OR=1.4-2.0, P<0.001) and stomach pain increased marginally with increasing pubertal development in girls. Rates of somatization, depression and probability of experiencing multiple pains also increased with pubertal development in girls (P<0.0001). For boys, prevalence of back (OR=1.9, P<0.0001) and facial pain (OR=1.5, P<0.01) increased, stomach pain decreased somewhat and headache prevalence was virtually unchanged with increasing maturity. For both sexes, pubertal development was a better predictor of pain than was age. Thus it appears that pain, other somatic symptoms and depression increase systematically with pubertal development in girls.

Abdominal pain: a surgical audit of 1190 emergency admissions

Abstract: In an audit of 1190 emergency admissions with abdominal pain (1166 patients) in a general surgical unit, the diagnosis was non-specific abdominal pain (NSAP) in 415 (35 per cent), acute appendicitis in 200 (17 per cent) and intestinal obstruction in 176 (15 per cent). The largest number of admissions occurred in the age groups 10-29 years (31 per cent) and 60-79 years (29 per cent). Surgical operations were performed in 551 patients (47 per cent) and there was a 16 per cent incidence of unnecessary appendicectomy (22 per cent in the age group 20-29 years). Fifty-one deaths resulted in a 30-day hospital mortality rate of 4.4 per cent and a perioperative mortality rate of 8 per cent. The mortality rate increased significantly in patients aged greater than or equal to 60 years, and patients aged 80-89 years had a perioperative mortality rate of 20 per cent. The causes of perioperative death included laparotomy for inoperable disease (28 per cent), ruptured abdominal aortic aneurysm (23 per cent), perforated peptic ulcer (16 per cent) and colonic resections (14 per cent). The perioperative mortality rates for ruptured aneurysm and perforated ulcer were 71 and 23 per cent respectively. The duration of inpatient stay increased significantly with the age of the patients, including those with NSAP. The results of the study indicate a need to review the methods of management of ruptured aortic aneurysm and perforated peptic ulcer, the methods of diagnosis of appendicitis, particularly in young females, and the factors that determine the duration of stay of patients suffering from NSAP.

A Randomized Controlled Trial of a Cognitive-Behavioral Family Intervention for Pediatric Recurrent Abdominal Pain

Abstract: Objective To investigate whether the combination of standard medical care (SMC) and short-term cognitive-behavioral family treatment (CBT) in the treatment of recurrent abdominal pain (RAP) was more effective than SMC alone. Methods Children recently diagnosed with RAP via physician examination were randomized into SMC (n = 29) and SMC plus CBT (n = 40) groups. Outcome measures included multiple dimensions of child and parent reported child pain, somatization, and functional disability, and school absences and physician contacts. Results Children and parents participating in the combined SMC + CBT intervention reported significantly less child and parent reported child abdominal pain than children in the SMC intervention immediately following the intervention and up to 1 year following study entry, as well as significantly fewer school absences. Significant differences in functional disability and somatization were not revealed. Conclusions These results, in combination with previous studies, add support to the effectiveness of CBT intervention in reducing the sensory aspects of RAP. Results are discussed with respect to the cost-benefit of integrated medical and short-term psychological services.

Bulking agents, antispasmodic and antidepressant medication for the treatment of irritable bowel syndrome.

Abstract: BACKGROUND Irritable bowel syndrome (IBS) is a common health problem, often presenting in primary care as well as in internal medicine and gastroenterology outpatient clinics. Therapeutic options are dominated by drug therapies but there is uncertainty about their effectiveness. OBJECTIVES The primary objective of this review was to evaluate the efficacy of bulking agents, antispasmodic and antidepressant medication for the treatment of IBS. SEARCH STRATEGY A computer assisted search of MEDLINE, EMBASE, PsychInfo and the Cochrane Library was performed for the years 1966-2001; local and national databases were searched in 10 European countries. SELECTION CRITERIA Randomised trials comparing bulking agents, antispasmodic or antidepressant medications with a placebo, in IBS patients over 12 years of age. Only studies published as a full paper were included. No language criterion was applied. DATA COLLECTION AND ANALYSIS The search identified 687 studies, 66 of which fulfilled all eligibility criteria. After removal of cross-over studies that did not report separately on the first phase, data from 40 studies remained for analysis. Relative risk (RR), risk difference (RD) and standardized mean difference (SMD) along with 95% confidence intervals were calculated for all subgroups. The number needed to treat (NNT) was also calculated where appropriate. MAIN RESULTS Forty-one study reports from 40 studies, comprising 78 comparisons, were analysed. These included 11 reports on bulking agents, 6 on antidepressants, and 24 on spasmolytics.BULKING AGENTS: Three studies comprising 159 patients reported a dichotomous outcome for relief of abdominal pain. The pooled RR using a random effects model was 1.22 (95% CI 0.86 - 1.73). Three studies comprising 128 patients reported a continuous outcome for relief of abdominal pain. Using the random effects model, the SMD was 0.68 (95% CI -0.86 - 2.33). Nine studies comprising 482 patients reported a dichotomous outcome for global assessment of improvement. The pooled RR was 1.09 (95% CI 0.78 - 1.50). Five studies comprising 253 patients reported a dichotomous outcome for improvement of symptom score. The pooled RR using a random effects model was 0.93 (95% CI 0.56 - 1.54). Two studies comprising 70 patients reported a continuous outcome for improvement of symptom score; the SMD using a fixed effects model was -0.44 (95% CI -1.20 - 0.31). SPASMOLYTIC AGENTS: Eleven studies comprising 1260 patients reported a dichotomous outcome for relief of abdominal pain. The pooled RR using a random effects model was 1.34 (95% CI 1.13 - 1.59; RD=0.17, 95% CI 0.06 -0.28; NNT=6, 95% CI 4 - 15). Seven studies comprising 467 patients reported a continuous outcome for relief of abdominal pain. Using a fixed effects model the pooled SMD was -0.65 (95% CI -0.94 to -0.35). Sixteen studies comprising 1236 patients reported a dichotomous outcome for global assessment of improvement. The pooled RR using a random effects model was 1.42 (95% CI 1.17 - 1.72; RD=0.20, 95% CI 0.09 -0.30; NNT=5, 95% CI 3 - 11). One study comprising 34 patients reported a dichotomous variable for improvement of symptom score. The RR was 1.33 (95% CI 0.96 - 1.85). Three studies reported a continuous outcome for improvement of symptom score; two studies comprising 66 patients could be pooled. Using a fixed effects model, the SMD was -0.37 (95% CI -0.85 - 0.12). ANTIDEPRESSANTS: Two studies comprising 81 patients reported a dichotomous outcome for relief of abdominal pain. Using the random effects model, the pooled RR was 0.83 (95% CI 0.33 - 2.12). Two studies comprising 101 patients reported a continuous outcome for relief of abdominal pain. The SMD using a random effects model was -0.53 (95% CI -2.29 - 1.23). Four studies comprising 241 patients reported a dichotomous variable for global assessment of improvement. The pooled RR was 1.16 (95% CI 0.78 - 1.73). AUTHORS' CONCLUSIONS The evidence for efficacy of drug therapies for IBS is weak. Although there is evidence of benefit for antispasmodic drugs for abdominal pain and global assessment of symptoms; it is unclear whether anti-spasmodic subgroups are individually effective. There is no clear evidence of benefit for antidepressants or bulking agents. The physician should be aware that global assessment is a construct containing various dimensions. For each individual, these will have a different weighting and treatment should be aimed at the most debilitating symptom. Stool problems are by definition part of the IBS symptom complex. Bulking agents may improve constipation and can be used empirically, but should be evaluated at an early stage for individual benefit. Future research should pay attention to study methodology and the use of valid outcome measures.

Pancreatic adenocarcinoma: Clinical Practice Guidelines in Oncology.

Abstract: Overall, in view of the relatively high likelihood of a poor outcome for patients with all stages of pancreatic cancer, the panel recommends that investigational options be considered in all phases of disease management. Specific palliative measures are recommended for patients with advanced pancreatic adenocarcinoma characterized by biliary or gastric obstruction, severe abdominal pain, or other tumor-associated manifestations of the disease.

Melatonin improves abdominal pain in irritable bowel syndrome patients who have sleep disturbances: a randomised, double blind, placebo controlled study

Abstract: Background and aims: Melatonin, a sleep promoting agent, is involved in the regulation of gastrointestinal motility and sensation. We aimed to determine if melatonin was effective in improving bowel symptoms and sleep disturbances in irritable bowel syndrome (IBS) patients with sleep disturbance. Methods: Forty IBS patients (aged 20–64 years; 24 female) with sleep disturbances were randomly assigned to receive either melatonin 3 mg (n = 20) or matching placebo (n = 20) at bedtime for two weeks. Immediately before and after the treatment, subjects completed bowel, sleep, and psychological questionnaires, and underwent rectal manometry and overnight polysomnography. Results: Compared with placebo, melatonin taken for two weeks significantly decreased mean abdominal pain score (2.35 v 0.70; p v −1.2 mm Hg; p Conclusions: Administration of melatonin 3 mg at bedtime for two weeks significantly attenuated abdominal pain and reduced rectal pain sensitivity without improvements in sleep disturbance or psychological distress. The findings suggest that the beneficial effects of melatonin on abdominal pain in IBS patients with sleep disturbances are independent of its action on sleep disturbances or psychological profiles.

Ischemic colitis: a clinical review.

Abstract: Ischemic colitis is the most common form of intestinal ischemia. It manifests as a spectrum of injury from transient self-limited ischemia involving the mucosa and submucosa to acute fulminant ischemia with transmural infarction that may progress to necrosis and death. Although there are a variety of causes, the most common mechanism is an acute, self-limited compromise in intestinal blood flow. Patients typically have mild abdominal pain and tenderness over the involved segment of bowel. There is usually passage of blood mixed with stool, but hemodynamically significant bleeding is unusual. Although computed tomography may have suggestive findings, colonoscopy is the procedure of choice for diagnosis. Supportive care with intravenous fluids, optimization of hemodynamic status, avoidance of vasoconstrictive drugs, bowel rest, and empiric antibiotics will produce clinical improvement within 1 to 2 days in most patients. Twenty percent of patients will have development of peritonitis or may deteriorate despite conservative management and will require surgery.

Review article: diagnosis and management of mesenteric ischaemia with an emphasis on pharmacotherapy

Abstract: Mesenteric ischaemia results from decreased blood flow to the bowel, causing cellular injury from lack of oxygen and nutrients. Acute mesenteric ischaemia (AMI) is an uncommon disorder with high morbidity and mortality, but outcomes are improved with prompt recognition and aggressive treatment. Five subgroups of AMI have been identified, with superior mesenteric artery embolism (SMAE) the most common. Older age and cardiovascular disease are common risk factors for AMI, excepting acute mesenteric venous thrombosis (AMVT), which affects younger patients with hypercoaguable states. AMI is characterized by sudden onset of abdominal pain; a benign abdominal exam may be observed prior to bowel infarction. Conventional angiography and more recently, computed tomography angiography, are the cornerstones of diagnosis. Correction of predisposing conditions, volume resuscitation and antibiotic treatment are standard treatments for AMI, and surgery is mandated in the setting of peritoneal signs. Intra-arterial vasodilators are used routinely in the treatment of non-occlusive mesenteric ischaemia (NOMI) and also are advocated in the treatment of occlusive AMI to decrease associated vasospasm. Thrombolytics have been used on a limited basis to treat occlusive AMI. A variety of agents have been studied in animal models to treat reperfusion injury, which sometimes can be more harmful than ischaemic injury. Chronic mesenteric ischaemia (CMI) usually is caused by severe obstructive atherosclerotic disease of two or more splanchnic vessels, presents with post-prandial pain and weight loss, and is treated by either surgical revascularization or percutaneous angioplasty and stenting.

Diagnosis and treatment of caecal volvulus

Abstract: Caecal volvulus is an infrequently encountered clinical condition and an uncommon cause of intestinal obstruction. Patients with this condition may present with highly variable clinical presentations ranging from intermittent, self limiting abdominal pain to acute abdominal pain associated with intestinal strangulation and sepsis. Lack of familiarity with this condition is a factor contributing to diagnostic and treatment delays. The objective of this review is to promote clinicians' awareness of this disease through patient case illustration, discussion of disease pathogenesis, clinical features, and management strategies.

Encapsulating peritoneal sclerosis--a clinician's approach to diagnosis and medical treatment.

Abstract: Encapsulating peritoneal sclerosis (EPS) is recognized as a serious complication of continuous peritoneal dialysis. A preliminary diagnosis of EPSis usually based on clinical signs and symptoms, which commonly include abdominal pain, nausea, vomiting, anorexia, abdominal fullness, an abdominal mass, bowel obstruction, and radiologic findings, including abdominal roentgenogram, contrast studies, ultrasound studies, and computed tomography. The diagnosis is confirmed by laparoscopy or laparotomy showing the characteristic gross thickening of the peritoneum enclosing some or all of the small intestine in a cocoon of opaque tissue. A variety of therapeutic approaches to EPS have been reported. This review discusses medical treatment of EPS and includes an overview of the clinical features and diagnostic aspects of the condition.

Testing a model of pain appraisal and coping in children with chronic abdominal pain.

Abstract: This prospective study of children with recurrent abdominal pain (N=133; ages 8--15 years) used path analysis to examine relations among dispositional pain beliefs and coping styles, cognitions and behavior related to a specific pain episode, and short- and long-term outcomes. Children believing they could not reduce or accept pain appraised their episode-specific coping ability as low and reported passive coping behavior. Dispositional passive coping had direct effects on both episode-specific passive coping and long-term symptoms and disability. Accommodative coping (acceptance and self-encouragement) was associated with reduced episode-specific distress, which itself predicted reduced depressive symptoms 3 months later. Results suggest that coping-skill interventions for children with chronic pain should target reductions in passive coping and consider the potential benefits of accommodative coping strategies.

Influence of cholecystectomy on symptoms

Abstract: A group of 292 consecutive patients underwent cholecystectomy for gallstones with presumed biliary pain over a 4-year period and all completed a self-assessment questionnaire before operation. Over the following 2 years 18 patients died but no others were lost to follow-up. The remaining 274 patients completed a further questionnaire 1 and 2 years after operation. Demographic characteristics and abdominal symptoms have been compared with an age- and sex-matched control group using the same questionnaire. Before operation symptoms of flatulent dyspepsia were far more frequent in patients with gallstones but operation markedly reduced these symptoms to an incidence which almost matched that of the control group. However, 1 year after cholecystectomy 34 per cent of patients still suffered some abdominal pain and of 35 patients referred back to hospital for investigation none has been shown to have a retained bile duct stone at a minimum follow-up of 5 years. A multivariate analysis indicated that preoperative flatulence together with long duration of attacks of pain are risk factors for postoperative dissatisfaction as judged by a linear analogue scale. However, both these factors are common and neither is a good discriminator of a poor outcome. The prediction of a poor symptomatic outcome after cholecystectomy from preoperative symptoms or patient characteristics had only limited success and all patients should be warned of this risk.

Chronic Abdominal Pain in Children: A Clinical Report of the American Academy of Pediatrics and the North American Society for Pediatric Gastroenterology, Hepatology and Nutrition: American Academy of Pediatrics Subcommittee on Chronic Abdominal Pain and NASPGHAN Committee on Abdominal Pain

Abstract: Children and adolescents with chronic abdominal pain pose unique challenges to their caregivers. Affected children and their families experience distress and anxiety that can interfere with their ability to perform regular daily activities. Although chronic abdominal pain in children is usually attributable to a functional disorder rather than to organic disease, numerous misconceptions, insufficient knowledge among health care professionals and inadequate application of knowledge may contribute to a lack of effective management. This clinical report accompanies a technical report on childhood chronic abdominal pain and provides guidance for the clinician in the evaluation and treatment of children with chronic abdominal pain. The conclusions are based on the evidence reviewed in the technical report and on consensus achieved among subcommittee members.

Adults with Williams syndrome.

Abstract: Reports of adults with Williams syndrome (WS) have been rare. We have evaluated 13 adult WS patients and reviewed 16 case reports of WS in patients older than age 16 years. Adults in our study had progressive multisystem medical problems. Cardiovascular complications were common (12/13) including hypertension (8), supravalvular aortic stenosis (9), aortic hypoplasia (3), pulmonic artery stenosis (4), peripheral stenoses (3), and mitral valve prolapse (2). Joint limitation (12/13) was progressive, often accompanied by kyphoscoliosis and lordosis. Recurrent urinary tract infections in 6 individuals led to radiologic studies showing urethral stenosis in 2, and bladder diverticula and vesicoureteral reflux in 3. Gastrointestinal problems included obesity (5), chronic constipation (7), diverticulosis (3), and cholelithiasis (4). Hypercalcemia was documented in 5 patients, although others had hypercalcemic symptoms (abdominal pain, polyuria, and constipation). One 45-year-old man had parathyroid hyperplasia. Previous reports likewise document significant morbidity. Thus, Williams syndrome in an adult appears to dictate aggressive evaluation and monitoring. Investigation of calcium metabolism should be undertaken in each adult WS patient.
