Treatment of "frozen shoulder" with distension and glucorticoid compared with glucorticoid alone. A randomised controlled trial.

This study is a comparison of treatments of idiopathic "Frozen Shoulder" (adhesive capsulitis), distension combined with steroid is compared with steroid alone. Evaluation was based on pain scales, analgesic usage, and range of motion outcome scales. Out of one-hundred twenty patients (age, mean 51, range 21-70) that were referred under the diagnosis FS, twenty-six fulfilled the criteria for inclusion in the study, but four patients did not want to participate in the trial, giving a total of 22 patients (age, mean 53, range 40-65) in the study. Patients were randomised by the envelope method. Two patients dropped-out, one in each treatment group thus leaving the study with 20 patients for the final statistical analysis. Eight were treated with steroid alone and 12 with distension combined with steroid. Patients received one treatment per week for a six weeks period with a follow-up at 12 weeks. They were evaluated by pain VAS on function and at rest within the study period, the different ranges of motion (ROM) were measured at inclusion time and subsequent afterwards at 3, 6, and 12 weeks. The VAS outcomes showed no difference between the treatments (VAS-function p=0,1; VAS-rest p=0.1), while in the distension group ROM showed significant improvement in all directions except extension (external p=0.0007, flexion p=0.03, extension p=0,01). The analgesic usage was significantly lower in the group treated with distension at the end of the study (p=0.008). A blinded clinical assessment of ROM also showed significant improvement (p=0.002). It is concluded that distension with steroid can seem to help in management of "Frozen Shoulder". Other studies seems to support the conclusion.

Intra-articular hyaluronan injections in the treatment of osteoarthritis of the knee: a randomised, double blind, placebo controlled multicentre trial. Hyaluronan Multicentre Trial Group.

OBJECTIVE: To assess the effects of intra-articular injections of hyaluronan on symptoms of knee osteoarthritis (OA). METHODS: Two hundred and forty patients with symptomatic, radiological knee OA were randomly assigned to treatment with weekly injections for five weeks with either 25 mg of high molecular weight hyaluronan or vehicle. Results were evaluated at weeks 1, 2, 3, 4, 5, 13, and 20 by visual analogue scales (pain, function, motion, activity), algofunctional index, and global evaluation by patient and investigator. Analysis was by "intention to treat', "per protocol', and area under the curve principles on unstratified patient groups and for patients stratified into four groups of equal size by age and baseline algofunctional index. RESULTS: No serious side effects were reported. At 20 weeks both treatment groups were improved compared with baseline, with no difference between unstratified groups treated with placebo or hyaluronan. Comparison of treatment groups stratified by age and baseline algofunctional index revealed a significant difference in favour of hyaluronan over placebo (pain, activity, algofunctional index, global evaluations by patient and investigator) for patients older than 60 years and with a baseline algofunctional index greater than 10. There was no clinically relevant difference between the two treatments for the other three stratified subgroups of younger age or fewer symptoms. Similar results were obtained by area under the curve, intention to treat, and per protocol analysis. CONCLUSIONS: Patients older than 60 years with knee osteoarthritis and with significant symptoms corresponding to an index of severity of knee disease of 10 or more, comprise the group most likely to benefit from treatment with intra-articular hyaluronan injections.

Severe low-back pain. I: Clinical assessment of two weeks conservative therapy.

A standard clinical examination was performed by two independent investigators, before and after two weeks of conservative therapy, on 33 patients with severe low-back pain. Kappa coefficients indicated a higher reproducibility of neurological tests than of e.g. muscular tenderness or scoliosis. All patients were diagnosed by CT-scan and a disc herniation was found in 20. The clinical diagnosis was more in agreement with the CT-diagnosis after than before treatment. By discriminant analyses six variables were found to classify the clinical diagnosis correctly in 32 of the 33 patients: sensory loss, ankle jerk, soreness of back extensors, lumbosacral soreness, radiating pain and back extension test. Similarly, the CT-diagnosis was classified in 25 of 33 patients by the variables: sensory loss and limping.

[Humero-scapular periarthrosis].

Humero-scapular periarthrosis (PH) is defined as an idiopathic painful condition in the shoulder with simultaneous limitation of active and passive movements in all directions. The condition is characterized by three phases: a painful period, a period dominated by stiffness and a period of recovery. PH is commonest between the ages of 40 and 60 years and the cumulated risk is estimated to be 2%. The incidence is higher in diabetics. The cause of PH is unknown and knowledge of the pathogenesis is very limited. Histological examination shows inflammation and fibrosis. Association with other pathological conditions of the upper limb or medical conditions, except diabetes mellitus, has not been documented with certainty. The average duration is 30 months but recovery without functional defects is common. Treatment is symptomatic and consists primarily of analgesics and rest during the painful phase. Local injections of steroids may be of effect. Exercises may be employed once the pain is under control and these have the object of improving mobility and increasing muscular strength.

Effect of osmotic pressure on uptake of chemotherapeutic agents by carcinoma cells.

Intraperitoneal chemotherapy has been used to treat cancers which are confined to the abdominal cavity. Several variables which affect drug delivery into tumor cells have been identified, but the effect of osmotic pressure has not been studied. Tumor cell lines were used to evaluate the effect of fluid tonicity on drug uptake. HeLa cells and a murine teratoma cell line were suspended in solutions of tonicities 154, 308, and 616 mosM, each containing the same quantity of 5-fluorouracil, and uptake of the drug was measured at different intervals over 30 min. At all time points the amount of 5-fluorouracil taken up by cells in solutions of 154 mosM was greater than that in 310 mosM solutions, which was greater than the uptake in 616 mosM solutions, each by an average of 40-50%. Incorporation of drug into tumor cells was also assayed in vivo using a teratoma cell line propagated i.p. in mice. Tumor cell uptake of doxorubicin was increased to a similar extent when this drug was administered in hypotonic solutions of 154 mosM and was decreased by administration in hypertonic solutions of 465 mosM, as compared to solutions of 310 mosM. These results demonstrate that the uptake of chemotherapeutic agents into tumor cells is increased significantly when these drugs are infused in solutions of lower osmolalities, a finding which may be exploited in clinical situations.

Frozen shoulder: current concepts.

The literature on frozen shoulder (FS) is reviewed. The etiology of FS is still not known and our understanding of the pathogenesis is limited. Studies on treatment programs under controlled conditions are few and incomplete. Further research is urgently needed.

[The rotator cuff syndrome--a frequent disease caused by loading].

The rotator cuff syndrome is defined as a cronical pain syndrome, originating from the rotator cuff with characteristic pain and referred pain. Disorders evolving from the rotator cuff and the rotator muscles comprise between 70 og 90% of the shoulder disorders. The rotator cuff syndrome may be of occupational origin, particularly in heavy work with tasks at or above shoulder level, e.g. shipyard welders and plate workers. Biomecanically surveys show that continuous blood flow in the rotator muscles ceases at about 30 degrees of flexion or abduction of the upper arm. Electromyographic examinations have shown high muscle tension in the same muscles in assembly plant employees. High prevalences of shoulder pain have been shown in these groups and it is considered that the workers are actually suffering from disorders in the rotator cuff and its muscles. The rotator cuff syndrome is on the list of occupational disorders in the Danish Workers' Compensation Act but, in the authors' experience knowledge on etiology, examination and treatment is insufficient. Diagnostic criteria are proposed with the object of improving clinical practice and medical insurance declarations.

[Alternative treatment of patients with rheumatism. The extent, effect and utilization of resources].

An anonymous questionnaire investigation involving 393 rheumatological patients showed that 185 patients (47%) had tried alternative treatment (52% of the women and 33% of the men). The three forms of treatment most commonly employed were chiropractor treatment, zone therapy and acupuncture. The 185 patients had, on an average, tried 2.2 types of treatment and 30% had tried more than two forms of treatment. One third of the patients had tried alternative treatment before or simultaneously with medical treatment while the remaining 2/3 had received medical treatment from weeks up to several years. The sources of information about alternative treatment were, most frequently, friends and relatives (70%) while in 16%, the general practitioner was the source. Only 58% replied to the question about the effect of the alternative treatment. Out of these, 56% had experienced improvement, 41% stated that there was no effect and 2% stated that deterioration had occurred. On an average, the patients had employed 2,444 Danish crows (approximately 200 pounds) for the alternative treatment. In addition, 6% stated that had spent more than 10,000 Danish crowns (approximately 833 pounds). It is concluded that alternative treatment frequently constitutes a considerable economical stress for the patients. Greater frankness and a increased level of information about the alternative forms of treatment are necessary.

A long-term randomised trial on tenoxicam and piroxicam in osteoarthritis of the hip or knee: a 24-month interim report focusing on the 12-24 month interval.

The long-acting antiphlogistics tenoxicam (Ro 12-0068, Tilcotil) and piroxicam in single daily oral doses of 20 mg are compared in a double-blind, group-comparative, randomised trial planned to last for five years. Results of 12 months' treatment of 108 patients with osteoarthritis of the hip or knee have been reported. This interim analysis focuses mainly on the 12 to 24 month interval. The clinical improvements obtained within the first 12 months persisted during the second year in the 55 patients remaining on treatment. After 24 months, 53 patients had been withdrawn prematurely, three-quarters because of inefficacy or intolerance. Only six patients were withdrawn between 12 and 24 months, three for lack of efficacy, two for side-effects and one for reasons unrelated to therapy. There was no difference between the treatment groups with regard to incidence, time or reason for withdrawal, and only small, insignificant differences in efficacy and tolerability. This trial shows that long-term treatment of osteoarthritis with tenoxicam and with piroxicam is beneficial. Once efficacy and tolerability have been established, maintenance of therapy is feasible.

Injection of steroids and local anaesthetics as therapy for low-back pain.

Thirty patients with low-back pain of at least one month's duration were included in a double-blind controlled study with third-party administration and treated with either methylprednisolone acetate mixed with lignocaine or isotonic saline, injected at the site of the iliolumbar ligament. The treatment was evaluated by a visual analogue scale, range of spinal flexion ad modum Wright & Moll and of the patients' self-assessments. In the methylprednisolone group, significant decreases in pain score and in patients' self-assessments were found. The range of spinal flexion did not undergo any significant change. No significant changes were found in the control group. No side effects were observed during the study.

The reflex dystrophy syndrome response to treatment with systemic corticosteroids.

Twenty-three patients with reflex dystrophy syndrome were randomly allocated to medication with oral prednisone, 10 mg thrice daily, or placebo, previous reports having indicated effect of systemic corticosteroids. The medication was continued until clinical remission, maximally 12 weeks. The diagnosis was based on fulfillment of at least four of seven criteria which included clinical, radiological and circulatory changes. All 13 patients in the prednisone-treated group showed more than 75% clinical improvement within the twelve-week period. Of the ten patients who received placebo, only two reported improvement. Prednisone appears to be superior to other treatment in reflex dystrophy syndrome, although the mode of action is not known.
