Long-term results of an intensive cognitive behavioral pain management program for patients with chronic low back pain: a concise report of an extended cohort with a minimum of 5-year follow-up.

PURPOSE: Treatment options for chronic low back pain (CLBP) include cognitive behavioral interventions. Most of these interventions only have small and short-lived effects. Using strict inclusion criteria for participation in an intensive combined physical and psychological program, encouraging effects were reported at 1-year follow-up. This study evaluates the long-term follow-up results of the same program. The hypothesis is that previously reported results are maintained. METHODS: Structured interviews were conducted in a prospective extended cohort with a minimum of 5-year follow-up in a similar fashion as in the 1-year follow-up report. The median follow-up in this cohort was 6.5 years. The extended cohort consisted of 277 patients (85% response). RESULTS: Outcomes include daily functioning, quality of life, current pain intensity, pain disturbance in daily activities and indicators of the use of pain medication and healthcare services. The previously reported positive 1-year follow-up results were maintained at a minimum of 5-year follow-up. Disability as measured with the Oswestry disability index (ODIv2.1a) decreased from 40 to 27 in the first year. This positive result was maintained at the 6.5-year follow-up with an ODI of 28. Pain intensity (NRS 0-100) improved from 60 to 39 in the first year, and at 6.5 years, this had further improved to 33. Improvement in quality of life (SF 36) at 1-year follow-up was maintained at 6.5-year follow-up, and healthcare consumption had decreased substantially as measured with doctor visits and analgesics used for CLBP. CONCLUSION: Selected and motivated patients with longstanding CLBP improve fast after an intensive combined physical and psychological program in daily functioning, pain and quality of life. Positive 1-year results are maintained, and healthcare utilization was still reduced at a minimum of 5-year follow-up. These slides can be retrieved under Electronic Supplementary Material.

Horizontal gaze palsy and scoliosis: a case report and review of the literature.

BACKGROUND: The syndrome of horizontal gaze palsy with progressive scoliosis (HGPPS) is a rare human disease and while its association with scoliosis was first reported in 1974, thirty years later the responsible genetic mutations are being elucidated. This progress was due to the reporting of single interesting cases. CASE DESCRIPTION: We present the case of a 27 year-old male patient who was admitted for elective scoliosis correction surgery and who represented after an uncomplicated discharge with headache and vomiting; because of a gaze palsy he underwent brain imaging that confirmed a brainstem abnormality, consistent with the syndrome of horizontal gaze palsy with progressive scoliosis (HGPPS), a rare autosomal recessive human disease. CONCLUSION: This rare syndrome is a good example of how single case reports can lead to advances in laboratory research and genetic characterisation of diseases, together with implications for neurodevelopment. Vigilance in the neurological examination in an otherwise 'non-neurological' scoliosis will help identify potential such cases, whilst further genetic/molecular analysis may shed further light into neuro-embryological development and patterning.

Circulating levels of the cytokines IL10, IFNγ and resistin in an obese mouse model of developmental programming.

An infant's early developmental environment plays a pivotal role in the programming of its physiological phenotype. The identification of the factors in the maternal environment that mediate the effects of maternal obesity and diet is essential to the development of clinical intervention strategies. Maternal hyperglycaemia, hyperinsulinaemia, hypertriglyceridaemia, hyperleptinaemia and altered inflammatory cytokines concentrations are potentially important predictive factors of her future offspring's susceptibility to metabolic disease. Using a diet-induced obese mouse model, we have investigated which of these maternal factors could induce adverse metabolic programming in the offspring. Female C57Bl/6 mice were fed either laboratory chow (10% fat) or high fat diet (42% fat) for 10 weeks before mating and throughout gestation. At day 18 of pregnancy, maternal body weight, body composition and glucose tolerance were measured, as well as plasma insulin, adiponectin, RBP4, leptin, resistin and the inflammatory cytokines (IL6, IL10, IL12, IL1ß, IFNγ, KC, TNF-α). At day 18 of pregnancy, high fat-fed dams were significantly heavier than the chow dams and had increased fat mass. High fat-fed dams had higher 5 h fasting blood glucose than chow dams and elevated plasma insulin. Although the obese dams had both reduced plasma adiponectin and resistin levels compared with lean dams, their plasma IL6, IL10 and IFNγ levels were all increased. High fat feeding in pregnancy leads to altered plasma concentrations of both adipokines and adipocytokines in the dam that may directly pass to the fetus and affect their development.

Leanness in postnatally nutritionally programmed rats is associated with increased sensitivity to leptin and a melanocortin receptor agonist and decreased sensitivity to neuropeptide Y.

BACKGROUND: Pups of normally nourished dams that are cross-fostered after birth to dams fed a low-protein (8% by weight) diet (postnatal low protein (PLP)) grow slower during the suckling period and remain small and lean throughout adulthood. At weaning, they have increased expression in the arcuate nucleus (ARC) of the hypothalamus of the orexigenic neuropeptide Y (NPY) and decreased expression of pro-opiomelanocortin, the precursor of anorexigenic melanocortins. OBJECTIVES AND METHODS: We investigated, using third ventricle administration, whether 3-month-old male PLP rats display altered sensitivity to leptin with respect to food intake, NPY and the melanocortin 3/4-receptor agonist MTII, and using in situ hybridization or laser capture microdissection of the ARC followed by RT-PCR, whether the differences observed were associated with changes in the hypothalamic expression of NPY or the leptin receptor, NPY receptors and melanocortin receptors. RESULTS: PLP rats were smaller and had reduced percentage body fat content and plasma leptin concentration compared with control rats. Leptin (5 µg) reduced food intake over 0-48 h more in PLP than control rats (P<0.05). Submaximal doses of NPY increased the food intake less in PLP rats than in controls, whereas submaximal doses of MTII reduced the food intake more in PLP rats. Maximal responses did not differ between PLP and control rats. Leptin and melanocortin-3 receptor (MC3R) expression were increased in both ARC and ventromedial hypothalamic nuclei in PLP animals compared with the controls. MC4R, NPY Y1R, Y5R and NPY expression were unchanged. CONCLUSION: Postnatal undernourishment results in food intake in adult rats being more sensitive to reduction by leptin and melanocortins, and less sensitive to stimulation by NPY. We propose that this contributes to increased leptin sensitivity and resistance to obesity. Increased expression of ObRb and MC3R may partly explain these findings but other downstream mechanisms must also be involved.

Polarization dependence of a GaAs-based two-photon absorption microcavity photodetector.

In this paper, the polarization response of a GaAs based two-photon absorption microcavity photodetector has been studied. The deviation in the dependence of the detector response from that of bulk GaAs is shown to be due to the birefringence of the cavity. A theoretical model based on the convolution of the cavity birefringence and the polarization dependence of two-photon absorption in GaAs is described and shown to match the measured polarization dependence of the microcavity detector very well.

Metabolic responses to BRL37344 and clenbuterol in soleus muscle and C2C12 cells via different atypical pharmacologies and beta2-adrenoceptor mechanisms.

BACKGROUND AND PURPOSE: Picomolar concentrations of the beta3-adrenoceptor agonist BRL37344 stimulate 2-deoxyglucose uptake in soleus muscle via undefined receptors. Higher concentrations alter uptake, apparently via beta2-adrenoceptors. Effects of BRL37344 and beta2-adrenoceptor agonists are compared. EXPERIMENTAL APPROACH: Mouse soleus muscles were incubated with 2-deoxy[1-(14)C]-glucose, [1-(14)C]-palmitate or [2-(14)C]-pyruvate, and BRL37344, beta2-adrenoceptor agonists and selective beta-adrenoceptor antagonists. Formation of 2-deoxy[1-(14)C]-glucose-6-phosphate or (14)CO2 was measured. 2-Deoxy[1-(14)C]-glucose uptake and beta-adrenoceptor mRNA were measured in C2C12 cells. KEY RESULTS: 10 pM BRL37344, 10 pM clenbuterol and 100 pM salbutamol stimulated 2-deoxyglucose uptake in soleus muscle by 33-54%. The effect of BRL37344 was prevented by 1 microM atenolol but not by 300 nM CGP20712A or IC3118551, or 1 microM SR59230A; that of clenbuterol was prevented by ICI118551 but not atenolol. 10 nM BRL37344 stimulated 2-deoxyglucose uptake, whereas 100 nM clenbuterol and salbutamol inhibited uptake. These effects were blocked by ICI118551. Similar results were obtained in C2C12 cells, in which only beta2-adrenoceptor mRNA could be detected by RT-PCR. 10 nM BRL37344 and 10 pM clenbuterol stimulated muscle palmitate oxidation. In the presence of palmitate, BRL37344 no longer stimulated 2-deoxyglucose uptake and the effect of clenbuterol was not significant. CONCLUSIONS AND IMPLICATIONS: Stimulation of glucose uptake by 10 pM BRL37344 and clenbuterol involves different atypical pharmacologies. Nanomolar concentrations of BRL37344 and clenbuterol, probably acting via beta2-adrenoceptors, have opposite effects on glucose uptake. The agonists preferentially stimulate fat rather than carbohydrate oxidation, but stimulation of endogenous fat oxidation cannot explain why 100 nM clenbuterol inhibited 2-deoxyglucose uptake.

Assignment of two loci for autosomal dominant adolescent idiopathic scoliosis to chromosomes 9q31.2-q34.2 and 17q25.3-qtel.

BACKGROUND: Adolescent idiopathic scoliosis (AIS) is the most common form of spinal deformity, affecting up to 4% of children worldwide. Familial inheritance of AIS is now recognised and several potential candidate loci have been found. METHODS: We studied 25 multi-generation AIS families of British descent with at least 3 affected members in each family. A genomewide screen was performed using microsatellite markers spanning approximately 10-cM intervals throughout the genome. This analysis revealed linkage to several candidate chromosomal regions throughout the genome. Two-point linkage analysis was performed in all families to evaluate candidate loci. After identification of candidate loci, two-point linkage analysis was performed in the 10 families that segregated, to further refine disease intervals. RESULTS: Significant linkage was obtained in a total of 10 families: 8 families to the telomeric region of chromosome 9q, and 2 families to the telomeric region of 17q. A significant LOD score was detected at marker D9S2157 Z(max) = 3.64 ( theta= 0.0) in a four-generation family (SC32). Saturation mapping of the 9q region in family SC32 defined the critical disease interval to be flanked by markers D9S930 and D9S1818, spanning approximately 21 Mb at 9q31.2-q34.2. In addition, seven other families segregated with this locus on 9q. In two multi-generation families (SC36 and SC23) not segregating with the 9q locus, a maximum combined LOD score of Z(max) = 4.08 ( = 0.0) was obtained for marker AAT095 on 17q. Fine mapping of the 17q candidate region defined the AIS critical region to be distal to marker D17S1806, spanning approximately 3.2 Mb on chromosome 17q25.3-qtel. CONCLUSION: This study reports a common locus for AIS in the British population, mapping to a refined interval on chromosome 9q31.2-q34.2 and defines a novel AIS locus on chromosome 17q25.3-qtel.

Inhibition of 11beta-hydroxysteroid dehydrogenase type 1 reduces food intake and weight gain but maintains energy expenditure in diet-induced obese mice.

AIMS/HYPOTHESIS: The 11beta-hydroxysteroid dehydrogenase type-1 inhibitor BVT.2733 lowers blood glucose and insulin in mutant mouse models of obesity and diabetes. Its effects on energy balance and body composition, and their contribution to improved glucose homeostasis have received little attention. MATERIALS AND METHODS: BVT.2733 (100 mg/kg, orally) was given twice daily to lean and diet-induced obese mice for 16 or 17 days. A group of obese mice was pair-fed to the amounts consumed by BVT.2733-treated mice. RESULTS: In both obese and lean mice, BVT.2733 reduced food intake and weight gain, but increased water intake. Pair-feeding caused almost as great a decrease in body weight as BVT.2733. Energy expenditure was 38+/-8% higher in the BVT.2733-treated obese mice than in the pair-fed mice. Terminal plasma corticosterone was raised, lean body weight reduced and percentage fat unchanged in the pair-fed mice (control, 47.8+/-2.6%; pair-fed, 47.1+/-1.9%), whereas BVT.2733 did not reduce lean mass, but did reduce percentage fat (40.9+/-2.0%). BVT.2733 but not pair-feeding reduced both the glucose tolerance AUC and the plasma insulin concentration 30 min after giving glucose. CONCLUSIONS/INTERPRETATION: BVT.2733 reduced food intake but prevented a concomitant reduction in lean body mass and energy expenditure. The latter effects may have contributed to improved glucose tolerance.

Analysis of an adult Duchenne muscular dystrophy population.

BACKGROUND: Advances in management have led to increasing numbers of patients with Duchenne muscular dystrophy (DMD) reaching adulthood. Older patients with DMD are necessarily severely disabled, and their management presents particular practical issues. AIM: To review the management of a late adolescent and adult DMD population, and to identify areas in which the present service provisions may be inadequate to their needs. DESIGN: Retrospective review. METHODS: We studied 25 patients with DMD referred to an adult neuromuscular clinic over a 7-year period. Clinical details were obtained retrospectively, from case notes or direct observations. RESULTS: There were 24 males and one symptomatic female carrier. Nine patients died during the observation period. There was no significant correlation between age of wheelchair confinement and age of death. Sixteen patients received non-invasive positive pressure support. Twelve attended mainstream schools and 12, residential special schools. All the patients lived at home for some or all of the time, when their main carers were either one or both of the parents. The most striking difficulties were with the provision of practical aids, including appropriate hoists and belts, feeding and toileting aids, and the conversion of accommodation. Patients rarely wished to discuss the later stages of their disease, and death was often more precipitate than expected. Death usually occurred outside hospital and the final cause was often difficult to establish. DISCUSSION: Adult patients with DMD develop progressive impairment, due to respiratory, orthopaedic and general medical factors. However, the particular areas of difficulty in this study often reflected inadequate and poorly directed social and medical support, illustrating the need for improvements in the structure, co-ordination and breadth of rehabilitation services for adult patients with DMD.

Modulation of susceptibility to weight gain and insulin resistance in low birthweight rats by treatment of their mothers with leptin during pregnancy and lactation.

OBJECTIVES: To investigate whether administration of leptin to rats during pregnancy and lactation affects placental 11beta-hydroxysteroid dehydrogenase (11beta-HSD2) activity and the susceptibility of their offspring to weight gain and insulin resistance. DESIGN: Pregnant rats fed on a low-protein diet were administered leptin or saline by subcutaneous minipump from day 14 of gestation and throughout lactation. A further group was fed a normal diet and given saline. After weaning, the offspring of each group were fed on a normal diet until 6 weeks of age and then half of each group was transferred to a high-fat diet until 12 months of age. RESULTS: Plasma leptin levels were raised two-fold on days 16-18 of pregnancy in the leptin-treated dams, but, despite a constant rate of infusion, at parturition they dipped to control levels before rising again. The activity of placental 11beta-HSD2 was reduced by the low-protein diet; this reduction was prevented by treating the dams with leptin. The male offspring of the saline-treated dams gained more weight and had higher plasma leptin levels on the high fat than the chow diet, but the offspring of the leptin-treated dams did not. Fasting blood glucose and intraperitoneal glucose tolerance at 6 and 12 months of age was unaffected by the high-fat diet, but only the offspring of the leptin-treated dams achieved this control without raised insulin levels. CONCLUSIONS: The rate of leptin clearance appears to increase at parturition. The administration of leptin to rats during late pregnancy and lactation makes their male offspring less susceptible to high-fat-diet-induced weight gain and insulin resistance.

Borderline nuclear change in cervical smears: five-year follow-up.

Borderline nuclear changes (BNC) account for 5-20% of cervical smears, and their outcome is unpredictable. Current management involves repeat smears at 6-mo intervals, for a further 12 mo with referral for colposcopy, if the changes persist. Given the uncertainty surrounding the natural history of BNC and the claim that many patients are further investigated unnecessarily and potentially "overtreated," the aim of this study was to determine the outcome for patients with a diagnosis of BNC to define whether the management protocol is appropriate for this patient group in our laboratory. A total of 808 patients with BNC were followed up. There was a 4.05% progression to high-grade dyskaryosis, and most of these were detected within the first year of follow-up. This at least justifies the early and intense follow-up of this patient group until a reliable "triage tool" is adopted to pre-select those patients with BNC who will progress or revert to negative.

Hexosamines and nutrient excess induce leptin production and leptin receptor activation in pancreatic islets and clonal beta-cells.

Activation of the hexosamine biosynthesis pathway leads to insulin resistance in muscle and adipose tissue. In these tissues leptin gene expression is increased by glucosamine. In the present study we found that glucosamine rapidly activates the production of leptin and OB-Rb, which encodes the functional leptin receptor, in both primary pancreatic islets and clonal beta-cells. Secretion of leptin from clonal beta-cells into the medium was detected readily. In addition, the level of the transcripts encoding signal transducer and activator of transcription-3 and -5, both implicated in leptin signal transduction in islet beta-cells, was increased by glucosamine, although to a lesser degree than mRNA levels of leptin and OB-Rb. High glucose (16.7 mM) induced leptin biosynthesis in primary pancreatic islet cells, and the addition of 1 mM palmitate caused an additional incremental effect. The hexosamine-mediated induction of the leptin system in clonal beta-cells was associated with increased responsiveness to leptin, as demonstrated by a 2.6 +/- 0.3-fold (P < 0.01) increase in tyrosine phosphorylation of signal transducer and activator of transcription-3. These findings are the first evidence of inducible leptin production in pancreatic islets and suggest that islet cells, like skeletal muscle, demonstrate a linkage between increased nutrient availability and both leptin expression and leptin responsiveness.

Clinical utility of measuring white blood cells on vaginal wet mount and endocervical gram stain for the prediction of chlamydial and gonococcal infections.

BACKGROUND: White blood cells on endocervical Gram stain and vaginal wet mount are frequently used to predict chlamydial and gonococcal infections. Previous studies provide conflicting evidence for the clinical utility of these tests. GOAL: To evaluate the clinical utility of measuring white blood cells on vaginal wet mount and endocervical Gram stain for the prediction of chlamydial infection and gonorrhea. STUDY DESIGN: Women undergoing pelvic examinations at 10 county health department family planning and sexually transmitted disease clinics were tested for chlamydial infection by ligase chain reaction assay (n = 4550) and for gonorrhea by culture (n = 4402). Vaginal wet mount and endocervical Gram stains were performed in county laboratories at the time of examination. RESULTS: The prevalences of chlamydial infection and gonorrhea were 8.8% and 3.2%, respectively. For detection of chlamydial or gonococcal infection, the likelihood ratio was 2.85 (95% CI, 2.10-3.87) for > 30 white blood cells on vaginal wet mount and 2.91 (95% CI, 2.07-4.09) for > 30 white blood cells on endocervical Gram stain. Similar results were seen for individual diagnoses either of chlamydial infection or of gonorrhea. CONCLUSION: Vaginal wet mount and endocervical Gram stain white blood cells are useful for the presumptive diagnosis of chlamydial infection or gonorrhea only in settings with a relatively high prevalence of infection or when other predictors can increase the likelihood of infection.

Laparoscopic lumbar spine surgery.

The use of transperitoneal endoscopic approaches to the distal segments of the lumbar spine has recently been described. This has been the catalyst for the development of other minimally invasive anterior approaches to the spine. This review looks at the published results so far, and highlights the principles, techniques and complications. The limitations of laparoscopic approaches have meant that surgeons are moving on to endoscopic extraperitoneal and mini-open approaches, but important lessons have been learnt during this short rapid phase of development. The efficacy and safety of minimal access techniques in the spine have been established, and outcome standards set by which future techniques can be judged. The importance of proper training is emphasised.

Selective screening for chlamydial infection: which criteria to use?

BACKGROUND: Screening sexually active women for Chlamydia trachomatis is necessary to detect asymptomatic infections. Selective screening is a common strategy because universal screening is too costly in many settings. In order to guide local programs in the choice of selective screening criteria, we examined the performance of previously proposed screening criteria for C. trachomatis. METHODS: A clinic-based, cross-sectional study was conducted in public family planning and sexually transmitted disease (STD) clinics in ten counties in North Carolina. Women (n = 4471 in family planning and n = 2201 in STD clinics) undergoing pelvic examination were enrolled consecutively. Nine sets of screening criteria, including age alone, were compared using sensitivity, specificity, number of tests required and receiver-operator characteristic (ROC) analysis. All women underwent testing with ligase chain reaction assay of cervical specimens to identify C trachomatis infection. RESULTS: The prevalence of C. trachomatis was 7.8% and 11.0% in family planning and STD clinics, respectively. The sensitivities of published criteria ranged from 0.50 to 0.97. Specificities ranged from 0.05 to 0.66. In family planning clinics, the best performing criteria would detect 84% of infections while screening 51% of women. In STD clinics, the same criteria would detect 83% of infections but require testing 67% of women. Testing women aged < or =22 would detect 77% of infections in family planning and 74% of infections in STD clinics, while testing 51% and 48% of the women, respectively. CONCLUSIONS: When site-specific criteria cannot be developed, age alone is an acceptable strategy for selective screening for chlamydial infection.

The effects of rexinoids and rosiglitazone on body weight and uncoupling protein isoform expression in the Zucker fa/fa rat.

Agonists for the retinoid X receptor (RXR), the rexinoids, and the peroxisome proliferator-activated receptor gamma (PPARgamma), the thiazolidinediones, are effective in the treatment of insulin resistance in rodent models by enhancing insulin action and improving glycemic control. In the present study, we compared the effects of rexinoids and a thiazolidinedione on body weight and mitochondrial uncoupling protein (UCP) isoform mRNA expression in the obese Zucker fa/fa rat. Long-term (2 weeks) oral treatment with the rexinoids LG100268 and LG100324 reduced food intake and body weight gain, whereas rosiglitazone (BRL49653) tended to increase both food intake and weight gain. LG100268 and LG100324 increased brown adipose tissue (BAT) UCP-1 mRNA content by 2.7-fold (P < .002) and 3.1-fold (P < .001), respectively, while BRL49653 had no effect on BAT UCP-1 mRNA content. Neither the rexinoids nor the thiazolidinedione had any effect on the level of mRNA encoding UCP-2 and the recently described PPARgamma coactivator-1 (PGC-1). LG100324 increased UCP-3 mRNA content by 3.6-fold (P < .0005) in muscle and 4.3-fold (P < .0002) in white adipose tissue (WAT). LG100268 increased UCP-3 mRNA content in WAT by 2-fold (P < .005) but was without any effect on muscle UCP-3. BRL49653 increased UCP-3 mRNA content by 2.1-fold (P < .005) in muscle and 2.7-fold (P < .003) in WAT. Thus, the rexinoids, but not the thiazolidinedione, have an antiobesity action by reducing food intake, and the increase in UCP-1 mRNA content in BAT may reflect a stimulation of BAT UCP-1 activity.

Do first impressions count? A comparison of subjective and psychologic assessment of spinal patients.

Psychologic factors may have a major influence on the outcome of treatment for back pain. Psychologic disturbance is manifest as emotional distress and may be associated with inappropriate symptoms and signs. Few outcome studies describe the patient population in terms of their psychologic profile. Anecdotal evidence suggested that the routine use of psychologic screening tests in British spine practice was rare. An audit of the prevalent use of psychologic testing amongst a selected group of British spinal surgeons was conducted. This was followed by a prospective, double blind comparison of subjective evaluations of patients with formal psychologic tests. The principal aim was to determine how accurately treating physicians could identify psychologically distressed patients. A postal questionnaire was sent to all consultant members of the British Orthopaedic Spine Society. Details of their current practice and frequency of use of psychologic tests was obtained. In a subsequent study, 125 consecutive new patients attending a back pain clinic were initially evaluated by questionnaires and classified as either psychologically distressed or non-distressed. These patients were then interviewed and examined by treating physicians, who then allocated them to one of four psychologic categories, using predefined criteria. The two results were compared and sensitivity, specificity and predictive values for the subjective evaluations were calculated. Sixty-three percent of respondents to the postal survey either never or only occasionally used any form of psychologic testing in assessing back pain patients. The follow-up prospective study demonstrated that experienced spinal surgeons achieved only a 26% sensitivity when trying to identify distressed patients. The specificity for identifying non-distressed patients was 96%. The predictive value of a "distressed" evaluation was 69%. The predictive value for non-distressed patients was 77%. Subjective psychologic assessment of back pain patients has a low sensitivity and predictive value for distressed patients. Formal psychologic screening should be routinely included in the clinical decision making process.

Osteoblastoma of the vertebral body of the third lumbar vertebra.

The case of a 22-year-old woman presenting with progressive low back pain as a result of a recurrent osteoblastoma of the body of L3, is reported. Total spondylectomy together with anterior and posterior fusion was carried out in a two-stage procedure. We highlight the rarity of the site of occurrence of osteoblastoma, the difficulty in diagnosis and the fact that a radical treatment needs to be performed.
