The effect of cervical traction on stabilometric parameters in cervical radiculopathy patients: A randomized crossover study.

BACKGROUND: Cervical traction is effective on pain and function in patients with cervical radiculopathy but its effectiveness on balance disorders has not yet been studied. OBJECTIVE: To evaluate the effect of mechanical intermittent cervical traction (MICT) on stabilometric parameters in patients with cervical radiculopathy. METHODS: This randomized crossover study assigned 20 patients with cervical radiculopathy to one of the two groups: Group effective traction (ET)/sham traction (ST) (n= 10) treated firstly with ET (traction force of 12 Kg) then with ST (traction force of 2 Kg) with one-week interval and group ST/ET (n= 10) treated invertedly with a ST then ET. Each traction procedure was maintained for 10 minutes twice separated by 5 minutes of rest. Patients were assessed before and immediately after MICT procedure. Main outcome measures were stabilometric parameters: center of pressure, sway area and lateral and anteroposterior displacements using a force platform. Secondary outcome measures were pain intensity, grip strength and dizziness. RESULTS: ET has provided a significantly greater improvement in both groups and in the total population in terms of stabilometric parameters (p< 0.01), pain intensity, and grip strength (p< 0.05), compared to ST. CONCLUSION: MICT seems to have an immediate beneficial effect on stabilometric parameters, pain and grip strength in patients with cervical radiculopathy.

Combined Hip Abductor and External Rotator Strengthening and Hip Internal Rotator Stretching Improves Pain and Function in Patients With Patellofemoral Pain Syndrome: A Randomized Controlled Trial With Crossover Design.

BACKGROUND: Active rehabilitation has an important role in the management of patellofemoral pain syndrome (PFPS). Although some studies have shown the benefit of hip-muscle strengthening, the effect of combining hip-muscle stretching with strengthening has not yet been defined. PURPOSE: To evaluate the effect of combined strengthening of the hip external rotators and abductors and stretching of the hip internal rotators on pain and function in patients with PFPS. STUDY DESIGN: Randomized controlled trial; Level of evidence, 2. METHODS: A total of 109 patients with PFPS (75 female and 34 male; mean age, 31.6 ± 10.8 years) were first randomly assigned to protocol A (n = 67) of the A-B arm (AB group; standard rehabilitation) or protocol B (n = 42) of the B-A arm (BA group; standard rehabilitation with strengthening of the hip external rotators and abductors and stretching of the hip internal rotators). Each protocol consisted of 3 sessions a week for 4 weeks. After a washout period, corresponding to a symptom-free period, rehabilitation programs were crossed over. A visual analog scale (VAS) evaluating perceived pain, the Functional Index Questionnaire (FIQ), and the Kujala score were administered at baseline, the end of each rehabilitation protocol, and 12 weeks after the completion of the second protocol for each group. RESULTS: Until the final follow-up, VAS, FIQ, and Kujala scores were significantly improved in both the A-B and B-A arms (P < .05 for all). Compared with protocol A, protocol B provided significant improvement in terms of pain and function in both the BA (VAS and Kujala; P < .001) and AB (VAS and Kujala; P < .001) groups. CONCLUSION: Combined strengthening of the hip abductors and external rotators with stretching of the hip internal rotators provided better outcomes, which were maintained for at least 12 weeks, in terms of pain and function in patients with PFPS.

Intra-articular distension preceded by physical therapy versus intra-articular distension followed by physical therapy for treating adhesive capsulitis of the shoulder.

BACKGROUND: Intra-articular distension is a validated treatment in adhesive capsulitis of the shoulder and is commonly followed by intensive in-patient physical therapy. A recent meta-analysis found that physical therapy is as effective as intra-articular distension (IAD) and that an early distension could be the primary choice for treating frozen shoulder. The question of the additional contribution of physical therapy prior to IAD compared with IAD followed by physical therapy has not been raised. OBJECTIVES: We compared IAD preceded by physical therapy to that followed by physical therapy in terms of pain relief and functional outcome. METHODS: We enrolled patients with primitive adhesive capsulitis of the shoulder. The eligible patients were randomized into three groups: A, B and C. Group A received intra-articular distension followed by physical therapy, group B received intra-articular distension in the middle of physical therapy and group C received physical therapy alone. Patients were assessed at the beginning of the protocol (T0), after 6 weeks (T1) and after 12 weeks (T2). The main outcome measures were pain using a Visual Analog Scale and the Disabilities of Arm, Shoulder and Hand Questionnaire. RESULTS: Out of the 179 enrolled patients, only 122 completed the follow up: group A (n= 34), group B (n= 46) and group C (n= 42). Compared to intra-articular distension preceded by physical therapy, IAD followed by physical therapy did not improve significantly the outcome in terms of pain relief (p= 0.123) but it enhanced the upper extremity function (p= 0.002). Upper extremity pain and function were found to improve with time regardless of the protocol (p< 0.001). CONCLUSIONS: IAD followed by physical therapy is more beneficial than IAD preceded by physical therapy in terms of upper extremity function. IAD, whether or not preceded by physical therapy, does not significantly improve pain compared to physical therapy alone. Time is a crucial factor to take into consideration while treating adhesive capsulitis of the shoulder.

[Discordance between spine and hip Bone Mineral Density measurement using DXA in osteoporosis diagnosis: prevalence and risk factors]. / Prévalence et facteurs de risque de discordance de la dentisté minérale osseuse au rachis lombaire et à la hanche dans diagnostic d'ostéporose.

BACKGROUND: Diagnostic discordance for osteoporosis is the presence of different categories of T-scores in 2 skeletal sites of an individual patient, falling into 2 different diagnostic categories identified by the World Health Organization classification. AIM: To determinate the prevalence and risk factors for T-score discordance between spine and hip measurement sites. METHODS: Demographic data, anthropometric measurements, and risk factors for osteoporosis were derived from a database of 1780 patients referred to the outpatient osteoporosis testing center of the departement of Rheumatology between September 2006 and February 2010. Bone mineral density (BMD) was performed by Dual-energy x-ray absorptiometry (DXA) on L1-L4 lumbar spine and total hips for all cases. Minor discordance was considered when the difference between 2 sites was no more than 1 World Health Organization diagnostic class. Major discordance was present when 1 site is osteoporotic and the other is normal. RESULTS: In 1780 participants (1606 women and 174 males; mean age, 59.5 ± 14.3 years), concordance of T-scores, minor discordance, and major discordance were seen in 49.4%, 45.7%, and 4.8% of the cases, respectively. In both minor and major discordance BMD was lower in lumbar spine than total hips. In univariate and multivariate logistic regression analysis only menopause was identified as risk factors against T-score discordance with p<0.001 and [OR=5.47; IC: 2.61- 12.79]. The others factors: age, gender, BMI, fracture history, corticotherapy, rheumatoid arthritis, tobacco and diabetes were not associated with the T-score discordance. CONCLUSION: Clinicians should expect that at least half of patients tested by DXA will demonstrate T-score discordance between spine and total hip measurement sites. T-score discordance can occur for a variety of reasons related to physiologic and pathologic patient factors as well as the performance or analysis of DXA itself.

[Survival prognosis factors in multiple myeloma]. / Les facteurs pronostiques de survie au cours du myélome multiple.

BACKGROUND: Outcome in multiple myeloma (MM) is very heterogeneous in survival and therapeutic response, constantly fatale despite her therapy progress. AIM: To determine the prognostic factors and survival in MM. METHODS: We carried out a transversal study of 100 patients in the rheumatology department of hospital Monastir between 1991 and 2010. In each case we determinate the survival delay and also the clinical, laboratory, radiological data at diagnosis and therapeutic response. RESULTS: The mean age was 64.4 years and sex ratio H/F=1.27. MM is IgG type in 57%, IgA in 28% and light chain in 11% of cases. The survival mean is 34 months and the survival median is 26 months. Univariate analysis showed five prognostic factors: age (p = 0.016), anaemia (p=0.033), ß2 microglobulin ( p < 0.0001) , CRP (p = 0.0001), albumin (p = 0.002), LDH (p=0.001), plasmocyte proliferation rate (p=0.003) and rapidly therapeutic response (p <0.001). ß2 microgrobulin-CRP classification and the international staging system (ISS) presented a high prognosis signification (p < 0.0001). Multivariate analysis demonstrated two prognostic factors: ß2 microglobulin and CRP. CONCLUSIONS: Our study showed that MM presented many prognostic factors, which easily realised in daly practice. These prognostic factors are essentially to evaluate prognosis and select patients for appropriate therapeutic indication. ß2 microgrobulin- CRP classification and the international staging system (ISS) are more predictive than Durie Salmon classification in MM survival.

Lipid profile in Tunisian patients with rheumatoid arthritis.

This study aims to assess the prevalence of dyslipidaemia in Tunisian patients with active RA and to investigate the clinical and biological associated factors. A cross-sectional study was conducted on 92 unselected patients with active RA (77 females and 15 males, aged 49.1 ± 12.5 years) and 82 healthy subjects (68 females and 14 males, aged 50.8 ± 13.3 years). We recorded the patients' characteristics and the results of a lipid profile test (total cholesterol, TC; high-density lipoprotein cholesterol, HDL-c; low-density lipoprotein cholesterol, LDL-c; triglyceride, TG; lipoprotein (a), Lp (a); apolipoprotein A-1, apo A-1 and apolipoprotein B, apo B). In comparison to the control group, RA patients showed a higher prevalence of associated dyslipidaemia (95.7% versus 65.9% of cases, p < 0.001). Sera of patients showed higher TC (4.86 ± 1.07 versus 3.98 ± 0.73 mmol/L, p < 0.001), LDL-c (3.49 ± 0.98 versus 1.99 ± 0.62 mmol/L, p < 0.001), Lp (a) (288.04 ± 254.59 versus 187.94 ± 181.37 mmol/L, p = 0.004) and lower HDL-c (0.66 ± 0.24 versus 1.12 ± 0.3 mmol/L, p < 0.001). TC/HDL-c, LDL-c/HDL-c and non-HDL-c/HDL-c were also higher in RA patients; they were 8.24 ± 3.20 versus 3.76 ± 1.26 (p < 0.001), 5.91 ± 2.48 versus 1.92 ± 0.99 (p < 0.001) and 7.24 ± 3.20 versus 2.76 ± 1.26 (p < 0.001), respectively. Apo A-1 was correlated to Lp (a) (r = 0.291, p = 0.005). Corticoid dose was not associated to dyslipidaemia, but in multiple regression models, corticoid dose may be negatively related to some atherogenic markers, in particular non-HDL-c. Tunisian patients with markedly active RA experience substantially reduced serum HDL-c and increased TC, LDL-c and Lp (a) concentrations as well as increased TC/HDL-c, LDL-c/HDL-c and non-HDL-c/HDL-c ratios.

[Quality of life in ankylosing spondylitis]. / Qualité de vie au cours de la spondylarthrite ankylosante.

BACKGROUND: Ankylosing Spondylarthritis (AS) involves by its frequency and its repercussion on the functional capacity an important handicap and deterioration of the patients quality of life. AIMS: To evaluate the handicap and the quality of life during the AS and to seek the predictive factors of the deterioration of this quality of life. METHODS: A prospective study relating to 50 patients recruited in the Department of Rheumatology of F. B. Hospital of Monastir during 6 months period (Mars to September 2008). The studied parameters were the quality of life evaluated by a specific sore (ASQOL) and a generic score (SF-12). Also the physical, social and economic felt handicap was evaluated using a qualitative scale. Predictive factors (clinical, biological and radiological) of the quality of life were carried out. RESULTS: Our patients are divided in 42 men and 8 women with an average age of 38.9 ± 10.7 years. The average duration of AS is of 11.9 ± 7.6 years. The average of ASQOL is of 11.9 ± 4 (extremes: 0- 17). The average of physical SF12 is of 29.8 ± 6 (21.7-53.2) and of mental SF-12 of 35.3 ± 6.6 (22.5-55.8). The physical, social and economic felt handicap was considered to be average or important in respectively 88%, 72% and 86% of the cases. The predictive factors of a high ASQOL (faded quality of life) are absence of occupation, high BASMI, a high number of painful articulations and high BASFI, BASDAI, BASG, BASRI and EVA total pain. The factors associated to the alteration of the quality of life according to SF-12'S are male sex, professional statute, high number of painful articulations and high BASDAI, BASFI and BASRI. CONCLUSION: Our study shows the important deterioration of the quality of life in AS patients. The existence of the predictive factors of quality of life primarily related to the functional capacity of the patients and to the disease activity implicates an early and adequate disease management in order to decrease this repercussion.

[The fracture risk assessment tool (FRAXTM), where are we in Tunisia?]. / Le score FRAX®, ou on est en Tunisie.

BACKGROUND: The fracture risk assessment tool (FRAXTM), published in February 2008, is developed based on the use of clinical risk factors with or without bone mineral density tests. AIM: To calculate the FRAX tool in a cohort of Tunisian patients in whom bone mineral density (BMD) was assessed by dual X ray absorptiometry (DXA); to correlate this score to osteoporotic fracture and to BMD assessment and to propose a threshold for therapeutic intervention. METHODS: In a cross sectional study of 582 patients older than 40 years, in whom a BMD measurement by DXA has been performed between January 2006 and December 2009, clinical risk factor for osteoporotic fracture and the occurrence of a prior fragility fracture were assessed. The French version of the FRAX tool was used. Threshold for pharmacological intervention was evaluated by ROC curve. RESULTS: Patients were aged 62.3 ± 10.4 years. They were female in 91.2% of cases. BMD measurement was under 2.5 standard deviation in 53.2%. Osteopenia was noted in 29.2% of cases and BMD was normal in 17.4 % of cases. Osteoporotic fractures were observed in 38.2% of cases. Major osteoporotic fractures (FOM) (hip, vertebra, radius occurred in 82% of cases. The FRAX® score calculated with T-score was 8.55 ± 8.54% for the FOM and 3.02 ± 6.37% for femoral neck (FN), while it was 7.81 ± 6.45% for the FOM and 2.58 ± 3.97% for the FN if calculated without T-score with a significant difference (p <10-3). For the patients having T-score under 2.5 SD, FRAX score was 11.39 ± 10.32% for the FOM and 4.74 ± 8.13% for the FN if calculated with T-score and it was 9.18 ± 6.95 % for the FOM and 3.19 ± 4.11 % if calculated without T-score. The score FRAX was correlated to BMD (r=0,53, p <10-3) and to fracture prevalence (p < 10-3). The threshold of therapeutic intervention was fixed to 30% for the FOM and 7% for the FN. CONCLUSION: Our study confirms the usefulness of the FRAX score in the prediction of fracture risk in Tunisian population. The determination of therapeutic threshold intervention requires other prospective and larger studies with medico-economic analyses.

[Safety of rheumatic disease drugs at childbearing age]. / Sécurité des médicaments à usage rhumatologique en âge de procréation.

The aim of this study is to determine the safety of commonly prescribed antirheumatic drugs at childbearing age, in pregnancy and lactation, through systematic literature review. Patients who take cytotoxic drugs should be informed of the risks of impared fertility. During pregnancy, non steroidal anti-inflammatory drugs (NSAIDs) can be safely administered until gestational week 32. Acetaminophen and low to moderate doses of corticosteroids are safe. Among, the disease-modifying agents, antimalarial agents, sulfasalazine, azathioprine and ciclosporin are compatible with pregnancy, and can be administered until birth. Paracetamol, prednison, antimalarial agents, sulfasalazine and most NSAIDs can safely be used by lactating mothers. To ensure a favourable outcome for both the mother and the child, the pregnancy should be planned, started during a period of disease stability, monitored closely and treated as needed.
