Relation among personality and symptoms in nonulcer dyspepsia and the irritable bowel syndrome

The importance of personality traits in nonulcer dyspepsia and irritable bowel syndrome is a controversial issue. We wished to assess the distribution of abnormal personality traits in nonulcer dyspepsia and the irritable bowel syndrome, define any relation among personality and symptoms, and determine whether personality factors discriminate among patients with functional, psychiatric, or organic gastrointestinal diseases. Patients with nonulcer dyspepsia (n = 31), irritable bowel syndrome (n = 67), organic gastrointestinal disease (n = 64), somatoform disorder (n = 36) and healthy controls (n = 128) were studied. Before diagnostic evaluation by an independent physician, all patients completed the Minnesota Multiphasic Personality Inventory and a symptom questionnaire. Symptom scores for abdominal pain and the Manning criteria, which is considered to be diagnostic for the irritable bowel syndrome, were evaluated. Personality scales in patients with nonulcer dyspepsia, irritable bowel syndrome, and organic disease were very similar. However, patients in the other groups differed from somatoform disorder on nearly all scales. In nonulcer dyspepsia, irritable bowel syndrome, and organic disease, hypochondriasis weakly correlated with pain. Subgroups of irritable bowel syndrome patients with predominant constipation and those with predominant diarrhea had similar personality traits, although hypomania was minimally increased in constipation. Patients who fulfilled the Manning criteria for irritable bowel syndrome had more psychological distress than those who did not. The Minnesota Multiphasic Personality Inventory correctly classified somatoform disorder and health 81% and 75% of the time, respectively, but it classified nonulcer dyspepsia and irritable bowel syndrome correctly in only 32% and 34% of cases. Our results suggest that psychopathology may not be the major explanation for functional gastrointestinal disorders.

The rumination syndrome: Clinical features rather than manometric diagnosis

BACKGROUND/AIMS Rumination is infrequent in adults of normal mental capacity. Upper gastrointestinal manometry reportedly confirms the diagnosis. Clinical characteristics, treatment(s), and outcomes of these patients are unclear. METHODS We assessed 38 adults and adolescents with rumination between 1987 and 1994. Esophagogastroduodenal manometric recordings (n = 36; 3-hour fasting and 2-hour postprandially) were reviewed; follow-up information was obtained from mailed questionnaires. RESULTS Patients saw a mean of five physicians and had symptoms for a mean of 2.75 years before diagnosis. Features included daily, effortless regurgitation of undigested food starting within minutes of meals. Weight loss was substantial (mean, 29 lb) in 42% of patients. Seventeen percent of female patients had a history of bulimia. Manometry confirmed the clinical diagnosis in 33% but was otherwise normal in all. Of 16 patients who responded to our questionnaires of 29 with > 6 months of follow-up (average, 35 months), 12 reported subjective improvement. In 14, the behavior persists. CONCLUSIONS The rumination syndrome is underdiagnosed. With typical clinical features, gastroduodenal manometry seems unnecessary to confirm the diagnosis. Diagnosis and reassurance are important in management to avoid unnecessary tests and treatments.

A longitudinal study of the efficacy of a comprehensive pain rehabilitation program with opioid withdrawal: Comparison of treatment outcomes based on opioid use status at admission

Abstract Use of opioids for chronic non‐cancer pain is controversial and the efficacy of comprehensive pain rehabilitation programs (CPRPs) that incorporate opioid withdrawal requires further investigation. We test the hypothesis that patients with chronic pain and longstanding opioid use who undergo opioid withdrawal in the course of rehabilitative treatment will experience significant and sustained improvement in pain and functioning similar to patients who were not taking opioids. A longitudinal design study compared 373 consecutive patients admitted to the Mayo Clinic Pain Rehabilitation Center at admission, discharge and six‐month posttreatment by opioid status at admission. Measures of pain severity, depression, psychosocial functioning, health status, and pain catastrophizing were used to assess between‐ and within‐group differences. Treatment involved a 3‐week interdisciplinary pain rehabilitation program focused on functional restoration. Over one‐half of patients (57.1%) were taking opioids daily at admission. The majority of patients (91%) completed rehabilitation and 70% of patients who completed the program returned questionnaires six months posttreatment. On admission, patients taking low‐ and high‐dose opioids reported significantly greater pain severity (P = .001) and depression (P = .001) than the non‐opioid group. Significant improvement was found on all outcome variables following treatment (P < .001) and six‐month posttreatment (P < .001) regardless of opioid status at admission. There were no differences between the opioid and non‐opioid groups upon discharge from the program or at six months following treatment. Conclusion: Patients with longstanding CPRP on chronic opioid therapy, who choose to participate in interdisciplinary rehabilitation that incorporates opioid withdrawal, can experience significant and sustained improvement in pain severity and functioning.

Prevalence and Clinical Correlates of Vitamin D Inadequacy among Patients with Chronic Pain

OBJECTIVE Vitamin D inadequacy is associated with medication refractory musculoskeletal pain and neuromuscular dysfunction. This vitamin deficiency could subsist as an unrecognized comorbid condition among patients with chronic pain. The primary objective of this study was to determine the prevalence and clinical correlates of vitamin D inadequacy in patients seeking treatment for chronic pain. DESIGN Retrospective case series. SETTING Multidisciplinary pain rehabilitation center at a tertiary referral medical center. PATIENTS The study involved 267 chronic pain patients admitted from February to December 2006. INTERVENTION Serum 25-hydroxyvitamin D (25[OH]D) was drawn at admission. OUTCOME MEASURES Patients with serum 25[OH]D levels < or=20 ng/mL were considered to have inadequate levels and those with levels >20 ng/mL were considered to have adequate levels. Upon admission, opioid intake was documented and patients completed the Short Form-36 Health Status Questionnaire. RESULTS The prevalence of vitamin D inadequacy was 26% (95% confidence interval, 20.6-31.1%). Among patients using opioids, the mean morphine equivalent dose for the inadequate vitamin D group was 133.5 mg/day compared with 70.0 mg/day for the adequate group (P = 0.001). The mean duration of opioid use for the inadequate and adequate groups were 71.1 months and 43.8 months, respectively (P = 0.023). Opioid users with inadequate levels reported worse physical functioning (P = 0.041) and health perception (P = 0.003) than opioid users with adequate levels. CONCLUSION The prevalence and clinical correlates identified in this pilot study provide the basis for the assertion that vitamin D inadequacy may represent an under-recognized source of nociception and impaired neuromuscular functioning among patients with chronic pain.

Chronic Noncancer Pain Rehabilitation With Opioid Withdrawal: Comparison of Treatment Outcomes Based on Opioid Use Status at Admission

OBJECTIVE To study differences in treatment outcomes between patients with chronic noncancer pain taking vs those not taking maintenance opioids at admission to a pain rehabilitation program. PATIENTS AND METHODS A nonrandomized 2-group prepost design was used to compare 356 patients admitted to the Mayo Comprehensive Pain Rehabilitation Center from January 2002 to December 2002 at admission and discharge by opioid status at admission. Measures of pain severity, interference due to pain, perceived life control, affective distress, activity level, depression, and catastrophizing (an exaggerated negative mental set associated with actual or anticipated pain experiences) were used to compare opioid and nonopioid groups. The patients entered a 3-week intensive outpatient multidisciplinary pain rehabilitation program designed to improve adaptation to chronic noncancer pain. The program uses a cognitive-behavioral model and incorporates opioid withdrawal. RESULTS More than one third of patients (135/356) were taking opioids daily at admission. At completion of the program, all but 3 of the 135 patients had successfully discontinued opioid treatment. No significant pretreatment differences were found between the opioid and nonopioid group regarding demographics, pain duration, treatment completion, or all outcome variables, including pain severity. Significant improvement was noted at discharge for all outcome variables assessed regardless of opioid status at admission. CONCLUSION Patients with symptomatically severe and disabling pain while taking maintenance opioid therapy can experience significant improvement in physical and emotional functioning while participating in a pain rehabilitation program that incorporates opioid withdrawal.

Randomized trial of dietician counseling to try to prevent weight gain associated with breast cancer adjuvant chemotherapy

This study was developed to test whether prospective dietician counseling could abrogate the unwanted weight gain seen among women receiving adjuvant chemotherapy for resected breast cancer. It was also designed to examine predictive factors for weight gain in an exploratory manner. Premenopausal women starting adjuvant chemotherapy for primary breast cancer were recruited for this trial. After appropriate stratification, they were randomized to a group which received monthly dietician counseling primarily aimed at weight maintenance versus a control group (whose attending physicians and nurses told them about possible weight gain but provided no formalized dietician counseling). One hundred and seven evaluable women were equally divided between the two protocol arms. The median weight changes 6 months after start of chemotherapy were gains of 2.0 kg in the dietician counseling group versus 3.5 kg in the control group. The median changes in average calorie consumption were reductions of 120 versus 46 cal/day on weekdays and 196 versus 20 cal/day on weekends for the counseling and control groups, respectively. Study data suggest that more weight was gained by patients with higher Quetelets indices (p = 0.01) and patients who had been on a diet in the preceding 6 months (p = 0.02). Routine prospective dietician counseling aimed at weight maintenance appeared to produce small but statistically insignificant reductions in both calorie consumption and weight gain in this group of patients.

The Effects of Smoking Status on Opioid Tapering Among Patients with Chronic Pain

OBJECTIVE: The primary aim of this study was to determine if smoking status affected the ability of patients with chronic pain to reduce opioid consumption during a 3-wk pain rehabilitation program. Secondary aims included determining the associations between smoking status, admission opioid use, and pain severity. METHODS: We used a retrospective, repeated measures design to assess pre- and post-treatment outcomes in a consecutive series of patients admitted to a 3-wk, outpatient pain treatment program from September 2003 through February 2007. Outcome measures included the frequency of successful opioid tapering, pain severity subscale of the Multidisciplinary Pain Inventory, and program completion status. RESULTS: The study cohort included 1241 patients (women 928); 313 (25%) smokers, 294 (24%) former smokers, and 634 (51%) never smokers. There were more smokers using opioids at admission (P < 0.001) compared to former and never smokers. Likewise, the mean morphine equivalent dose (P = 0.013) and pain severity scores (P < 0.001) of smokers were higher compared to former and never smokers. The success of opioid tapering did not depend on smoking status, and all groups experienced significant reductions in pain severity at program completion (P < 0.001). However, a higher proportion of smokers did not complete treatment (P < 0.001). CONCLUSIONS: For patients completing a pain rehabilitation program, most were able to eliminate opioid use, regardless of smoking status. However, significantly more smokers did not complete treatment. The most frequent reasons for program noncompletion included discrepant expectations of treatment, acute illness, and psychosocial stressors.

Psychological disorders in patients with evacuation disorders and constipation in a tertiary practice

OBJECTIVE:We aimed to evaluate the prevalence of psychological impairment in patients with rectal evacuation disorders and the influence of psychological disorder on the early outcome of behavioral treatment.METHODS:We retrospectively reviewed the medical records of patients with rectal evacuation disorders referred for biofeedback retraining at a tertiary referral center. The psychological disorder was classified using the DSM IV criteria. Outcome of biofeedback treatment of evacuation at 2 wk was based on symptoms or on the ability to spontaneously expel a balloon placed in the rectum. Improvements in the groups without versus with a psychological disorder or an eating disorder were compared by Fishers exact test.RESULTS:In the 60 patients (55 women; 5 men; mean age, 38 yr), psychological disorders were identified in 39 (65%); also noted were eating disorder (n = 5), rumination syndrome (n = 3), pain disorder (n = 6), anxiety-depression (n = 10), a combination of depression and pain disorder (n = 3), and a combination of eating disorder with anxiety-depression and pain disorder (n = 12). There was an association between psychological status and outcome at 2 wk of behavioral treatment for evacuation disorder (p = 0.03). The coexistence of eating disorder and psychological disorder resulted in an unfavorable outcome (p = 0.02), compared with those without psychological disorder.CONCLUSION:Psychological impairment was identified in 65% of the patients with evacuation disorder and constipation in a tertiary care practice, and has a significant negative impact on the outcome of behavioral treatment. These data reinforce the importance of a multidisciplinary approach in the management of these patients.

Effects of smoking status on immediate treatment outcomes of multidisciplinary pain rehabilitation

OBJECTIVE The primary aim of this study was to determine the effects of smoking on treatment outcomes following multidisciplinary pain rehabilitation. A secondary aim was to assess the tobacco use characteristics of smokers with chronic pain. DESIGN A prospective, nonrandomized, repeated measures design. SETTING Multidisciplinary pain rehabilitation center at a tertiary referral medical center. PATIENTS All patients (N = 193) consecutively admitted from August 2005 through February 2006. INTERVENTIONS A 3-week outpatient multidisciplinary pain rehabilitation program. OUTCOME MEASURES The Multidimensional Pain Inventory (MPI), Short Form-36 Health Status Questionnaire (SF-36), Center for Epidemiologic Studies-Depression scale (CES-D), Pain Anxiety Symptom Scale (PASS-20) and Pain Catastrophizing Scale (PCS) were administered at admission and dismissal. RESULTS The study involved 49 (83% women) smokers and 144 (83% women) nonsmokers. The mean number of cigarettes smoked daily was 17.5 (SD 11.1) and the mean duration of smoking was 21.5 years (SD 12.1). After adjusting for demographic differences, repeated measures of analysis of covariance showed a main effect of smoking status for MPI affective distress (P = 0.008), CES-D (P = 0.001) and PCS (P = 0.011). An interaction of smoking status and time was found for the PASS-20 (P = 0.028), MPI affective distress (P = 0.033), MPI life control (P = 0.003) and SF-36 role-emotional (P = 0.004) subscale. While the majority of smokers were ready to consider smoking abstinence, 43% declined a brief smoking cessation intervention. CONCLUSIONS In this series of patients undergoing multidisciplinary treatment for chronic pain, immediate treatment effects for a variety of outcome measures were similar or significantly better in smokers compared with nonsmokers.

Inpatient treatment of severe nicotine dependence

The most severely nicotine-dependent patients who have tried traditional treatment programs without success may require maximal intervention to achieve abstinence. In the Clinical Research Center at the Mayo Clinic, we assessed the feasibility of an inpatient treatment program for 24 such subjects, who were hospitalized (in groups of 6) for 2 consecutive weeks. A combination of behavioral, chemical-dependence, and transdermal nicotine-replacement therapy was provided in a smoke-free, protected milieu. Components of the program included group therapy, management of stress, exercise, daily lectures, and supervised activities. The mean age of the 18 women and 6 men was 51.3 years (range, 29 to 69 years). The mean duration of smoking was 33.7 years, and the number of cigarettes smoked per day at the time of admission averaged 33.2. The most frequent tobacco-related medical illnesses were chronic obstructive pulmonary disease, arteriosclerosis obliterans, and coronary artery disease. All subjects but two--each smoked part of a cigarette--remained abstinent from the use of cigarettes while in the Clinical Research Center, and all completed the 2-week inpatient program. The subjects underwent follow-up for 10 weeks after dismissal and were contacted periodically thereafter. At 1 year, 7 of the 24 subjects (29%) had maintained continuous abstinence from smoking, and their self-reported status at 1 year was verified biochemically.
