The aim is to evaluate the efficiency of the treatment with 153-samarium hydroxyapatite (153-Sm-HA) in haemophilic arthropathy. Thirty-one patients (30 males) with ages ranging from 8 to 34 years (average age = 20.6 years) were treated with fixed intra-articular dose of 185 MBq (5 mCi) and divided into two groups: infantile-juvenile (13 patients with up to 18 years of age, an average age of 12.7 years and arthropathy evolution of 7.8 years), and adult (18 patients older than 18 years, an average age of 24 years and arthropathy evolution of 18.7 years). The clinical evaluation before and after 1 year of synovectomy used the following criteria: subjective (pain through visual scale, articulation inspection), objective (articular movement through flexion level, sensitivity to palpation and leakage through joint circumference), reduction on the use of the coagulation factor, number of haemarthrosis, and the occurrence of adverse effects. The results were classified as: 1, good (remission from 70% to 100% of manifestations); 2, moderate (remission from 40% to 69%); and 3, poor (remission from 0% to 39%). Seventy-eight joints were tested: 15 knees, 36 elbows, 24 ankles, 1 shoulder and 2 hips. Early scintigraphic (1-2 h) and late scintigraphic (24-72 h) studies were performed after synoviorthesis. The cost of the procedure per joint was also estimated. No significant difference in the synoviorthesis result between groups was observed. The results were good for 75% of elbows, 87.5% of ankles and 40% of knees; the reduction in haemarthrosis and use of the coagulation factor was respectively 78% and 80% for elbows, 82% and 85% for ankles and 30% and 35% for knees. Four cases of reactional synovitis were observed in the 31 patients. The scintigraphic control showed homogeneous distribution of the material with no articular escape. The use of 153 Sm-HA in the treatment of the haemophilic arthropathy is effective for intermediate-size joints (elbows and ankles), but less effective for knees. Moreover, this treatment presents an excellent safety profile and accessible cost.

The penetration of beta energy of 153-samarium (153Sm) (0.8 MeV) is not only appropriate for synovectomy of median articulations but is possible to improve the radiobiological effect using increased activities. The aim of this study was to assess the effectiveness of 185 MBq and 740 MBq of 153-samarium hydroxyapatite (153Sm-HA) in knees of haemophilic patients. Thirty-one patients – 36 knees, 30 males, were divided into two groups without coinjection of corticosteroid: A – 14 patients (17 knees) treated with intra-articular dose of 185 MBq of 153Sm-HA, average age 23 years; B – 17 patients (19 knees) with 740 MBq of 153Sm-HA, average age 21.3 years. The evaluation before and after 1 year of synovectomy used the following criteria: reduction in the number of haemarthroses and use of the coagulation factor and improvement in articular motility. Adverse-effects occurrence was considered too. Early and late scintigraphic studies were performed after synoviorthesis and no joint immobilization was recommended. The reduction in haemarthrosis and use of coagulation factor were: group 1 – 31.3% and 25%; group 2 – 81.5% and 79% with P < 0.001 respectively; no significant improvement in knees motility was noted for both groups. Four cases of mild reactional synovitis were observed in each group. The scintigraphic control showed homogenous distribution of the radiopharmaceuticals with no articular escape; the material was considered safe by its permanence in the articulation. We have significant improvement in the synovectomy of haemophilic knees with 740 MBq of 153Sm-HA; the less penetration of its beta radiation was compensated by the increased biological effect with the higher used activity.

This study aimed to evaluate synovectomy with samarium-153 hydroxyapatite (153Sm-HA) in synovitis of the elbows and ankles of hemophilic patients. The synovectomy was performed using 185 MBq of 153Sm-HA in 166 joints of 82 hemophilic patients, with a mean age of 24.4 years and follow-up of 12 and 42 months, comprising 63 ankles and 84 elbows. Arthropathy was characterized by recurrent joint bleeding. Episodes of hemarthrosis, use of clotting factors, and pain intensity were evaluated before and after treatment. Scintigraphic controls and adverse effects were also considered. Statistical analyses used P ≤ 0,005 as significant. The results pointed that (a) reduction in hemarthrosis was 78% and 68% in elbows and 82% and 72% in ankles; (b) use of clotting factors was 80% and 70% in elbows and 85% and 75% in ankles; (c) pain was 37% and 34% in elbows and 61% and 57% in ankles, after 12 and 42 months, respectively. Three cases of mild reactive synovitis were observed in ankles and four in elbows. There was no joint effusion in any of the cases. In conclusion, the use of 153Sm-HA in elbows and ankles was effective, very safe, minimally invasive and showed consistency over time, is another material to utilize in median hemophilic joints.

This analysis will explore the corporate governance of the Kuwait Finance House. Given that the institution is a market leader, it encompasses the revolutionary financial mall concept whereby it groups together partners such as telecommunication, insurance and also credit card providers. The concept of the financial mall is providing a degree of ease through convenient services for customers, automated systems and also financial advisors. The analysis will explore the major challenge that Kuwait Finance House is facing and also the conflict of interest between the managers and the shareholders. The analysis will utilize descriptive research study whereby interviews will be conducted to get a scope of the operation of the institution. The analysis will offer recommendations such as involvement of the customers before internal growth investment. It should also establish the reason for the conflict between the shareholders and the managers and also why the financial house requires corporate governance. Given the bank has a separate clause that defines their creation of wealth for the shareholder, the conflict between the manager will eventually result in a stunted growth of the customer deposit, shareholder equity and the total assets which are important financial indicators.
