Chemical synoviorthesis with oxytetracycline clorhydrate (Emicine) in recurrent haemarthrosis.

This is a non-controlled experimental prospective clinical study that evaluates the satisfactory results in the chemical synovectomy (synoviorthesis) with oxytetracycline clorhydrate (Emicine, Lab. Pfizer Ltda, Guarulhos, Sao Paulo, Brazil) in recurrence haemarthrosis in different joints, demonstrating that it is an effective method in the treatment of these recurrent haemarthrosis in haemophilia. 84 patients of whom 77 concluded the full course of treatment. 82 joints were injected. The dosage injected was 5 cm(3) of the drug (25 mg) in 5 cm(3) of anaesthesia for the knee, 2 cm(3) with 1 cm(3) of anaesthesia for the elbow and 1 cm(3) plus 1 cm(3) of anaesthesia for the ankle. These injections were administered once weekly with a reinforcement in 1 month. In case of failure the same can be administered repeatedly. Subjective parameters included pain, range of movement and use of the joint involved. Pain decreased from a mean of 6.5 to 0.9 (Likert scale). Range of movement increased from 5.9 to 9 and joint use increased from 5.9 to 9.2. Objective parameters included joint diameter and range of movement. Range of movement for flexion and extension improved from 72.2 and 149.2 to 73.7 and 167, respectively, for the knees. From 57.3 and 160 to 66.6 and 170, respectively, for the shoulder. And, from 22.7 and 10.8 to 34 and 18.6, respectively, for the ankle. This procedure has multiple advantages such as immediate therapeutic effect, short period of treatment, easy technique, much less AHF coverage (30% above coagulation level), less costly than radiocolloid treatment, which make it a perfect alternative treatment for developing countries.

Synovectomy with rifampicine in haemophilic haemarthrosis.

The purpose of this paper was to assess the effectiveness of intra-articular injected rifampicine in haemophilic patients in order to achieve synovectomy by preventing repeated intra-articular bleeding. We have used this technique in haemophilic patients previously and reported our results on 13 cases [1]. Two hundred and fifty milligrams of rifampicine was injected into the elbow and ankle joints and 500 mg was injected into knee joints with 3-10 mL of lidocaine, depending on the joint size. The injections were repeated once a week for 7 weeks. Patients were only covered with antihaemophilic factor on the day of the injection at 30% above their coagulation level. We evaluated the results using two measures: subjective reports from the patient and objective assessment by the examiner. In the subjective reports the patient graded the results from their own perspective from 1 (poor) to 10 (excellent): 1-3, poor; 4-6, fair; 7-8, good; and 9-10, excellent. In the objective reports the grading was: excellent ('dry joint', full function, no haemarthrosis, no synovitis); good (clinical improvement, synovitis, reduction of haemarthroses, full function); fair synovitis (reduction of haemarthroses, no change in function); poor synovitis (persistent haemarthroses). This paper reports on the results of 38 patients with 39 joints with more that 3 years follow up, mean 1.8 years. There were 22 knees, nine elbows and eight ankles. Subjectively, there were excellent results in 21 joints (11 knees, six elbows and four ankles) good results in 15 joints (eight knees, three elbows and four ankles), fair results in two knees and a poor result in one knee. Objectively, results obtained were excellent in 20 joints (11 knees, six elbows and three ankles); good in 17 (nine knees, three elbows and five ankles); fair in one knee and poor in one knee.

Hematomas within the iliopsoas muscles in hemophilic patients: the Latin American experience.

The majority of bleeding episodes in patients who have hemophilia occur within the musculoskeletal system, primarily in the joints, but approximately 30% occur within the muscles. Iliopsoas muscle bleeding episodes are often large in volume, causing muscular function inhibition, angular deformities, and nerve involvement. Recurrent hemorrhages are common (14.2%) and neural involvement is as high as 37%. Three hundred patients are being observed in the authors' hemophilia center, 63 of whom have suffered 127 hemorrhages. Absolute bed rest and long term factor replacement are the mainstay of therapy. The experiences of physicians in other countries are appendixed to this article.
