Comorbid subjective health complaints in patients with sciatica: a prospective study including comparison with the general population.
ABSTRACT Chronic nonspecific low back pain is accompanied by high rates of comorbid mental and physical conditions. The aims of this study were to investigate if patients with specific back pain, that is, sciatica caused by lumbar herniation, report higher rates of subjective health complaints (SHCs) than the general population and if there is an association between change in sciatica symptoms and change in SHCs over a 12-month period.
A multicenter cohort study of 466 sciatica patients was conducted with follow-up at 3 months and 1 year. Comorbid SHCs were measured by 27 items of the SHC inventory. Odds ratios (ORs) for each SHC were calculated with comparison to a general population sample (n=928) by logistic regression. The SHC number was calculated by summing all complaints present.
At baseline, the ORs for reporting SHCs for the sciatica patients were significantly elevated in 15 of the 27 items with a mean (S.D.) SHC number of 7.5 (4.4), compared to 5.2 (4.4) in the general population (P<.01). Among those who during the 1-year follow-up period fully recovered from their sciatica, the SHC number was reduced to normal levels. Among those with persisting or worsening sciatica, the number increased to a level almost double that of the general population.
Compared to the general population, the prevalence of subjective health complaints in sciatica is increased. During follow-up, the number of health complaints increased in patients with persisting or worsening sciatica.

ABSTRACT: Earlier observations show that development of persistent pain may be associated with the genetic variability in the gene encoding for the mu-opioid receptor 1, the OPRM1 A118G (rs1799971). The aim of this study was to investigate the association between OPRM1 genotype and subjective health complaints in patients with radicular pain and disc herniation.BMC Musculoskeletal Disorders 05/2014; 15(1):161. · 1.88 Impact Factor

ABSTRACT: Objectives Somatic/psychiatric symptoms are frequently found in chronic pain patients (CPPs). The objectives of this study were to determine 1) which somatic/psychiatric symptoms are more commonly found in acute pain patients (APPs) and CPPs vs community nonpatients without pain (CNPWPs) and 2) if somatic/psychiatric symptom prevalence differs between APPs and CPPs.DesignThe above groups were compared statistically for endorsement of 15 symptoms: fatigue, numbness/tingling, dizziness, difficulty opening/closing mouth, muscle weakness, difficulty staying asleep, depression, muscle tightness, nervousness, irritability, memory, falling, nausea, concentration, and headaches.ResultsAfter controlling for age, gender, and level of pain, APPs and CPPs had a statistically significantly greater prevalence (at a P < 0.01 level) for 11 and 13 symptoms, respectively, vs CNPWPs. After controlling for age, gender, and level of pain, CPPs had a statistically significantly greater prevalence (at a P < 0.01 level) for eight symptoms vs APPs. Symptoms were highly correlated in both APPs and CPPs.ConclusionsCPPs are characterized to a significantly greater extent than comparison groups by somatic/psychiatric symptoms that are highly intercorrelated. This has implications for clinical practice and future research.Pain Medicine 09/2014; · 2.46 Impact Factor

ABSTRACT: Chronic low back pain (CLBP) has a significant effect on quality of life and imposes a great economical burden on society. In a number of studies, validated questionnaires had been given to CLBP patients to determine their health-associated quality of life, sleep disturbance, and psychological status. However, such outcome studies had not been performed previously in Korea.Korean journal of anesthesiology. 06/2014; 66(6):444-50.
