The p48MW Flow Diverter-Initial Human Experience.

BACKGROUND AND PURPOSE: The use of flow diverters to treat aneurysms arising from small caliber parent vessels has been reported. This article reports the results of the first in experiences with the p48MW (p48 Movable Wire) in humans, a device specifically designed to target vessels 1.75-3 mm in diameter. METHODS: This monocentric study retrospectively reviewed the prospectively maintained database to identify all patients treated with the p48MW device between January 2017 and January 2019 at this institution. Patient demographics, aneurysm characteristics, angiographic and clinical follow-up were recorded as well as complications. RESULTS: A total of 25 patients (20 female) with an average age of 55 ± 12.9 years (range 34-84) with 25 aneurysms were identified. The majority of the aneurysms was located in the anterior circulation (19/25, 76%). The average aneurysm dome width was 3.98 ± 3.6 mm (range 1.2-13 mm). Complete occlusion was seen in 18/24 (75%) aneurysms with neck remnants in 1/24 (4.2%) and continued aneurysm filling seen in the remaining cases (5/24, 20.8%). Adequate occlusion was seen in 79.2% of aneurysms (Raymond Roy Classification [RRC] grade I or II) during the follow-up period. There was a single technical complication with inappropriate deployment of the first p48MW. There was a single clinical complication (4%); however, the patient made a complete recovery (modified Rankin Scale [mRS] 0) and one patient died secondary to uncontrollable status epilepticus following acute subarachnoid hemorrhage unrelated to the treatment. CONCLUSION: The p48MW is safe and effective for the treatment of aneurysms including those arising from distal vessels.

[Large multifocal basal cell carcinoma in a young man]. / Extenso carcinoma basocelular multifocal en un hombre joven.

We present an unusual large Basal cell carcinoma (7 x 7 cms.) which occurred on the cheek and temple of a 31 year old man. The lesion had been present since the age of 25 and had been excised twice previously. Following Mohs surgery fresh tissue technique his tumor has not recurred after one ye ar. Histologically the lesion was morphea in type and multifocal in origin, arising both in the epidermis and the hair follicle sheath.

Radioactive synoviorthesis in hemophilic hemarthrosis: materials, techniques, and dangers.

Radioactive synoviorthesis with 198Au, 90Y, 186Re, and 31P would seem to be the treatment of choice for recurrent hemarthroses in hemophilia. The clinical results, obtained by different centers, show a definite diminution of hemarthroses in 88% of cases. The advantages of radioactive synoviorthesis compared with surgical synovectomy are: better results, the requirement of substantially reduced antihemophilic factor, the possibility of performing the procedure on multiple cases concurrently on an ambulatory basis, no interference with articular range of movement, and the low cost of the procedure. In cases of failure, the procedure can be repeated after 6 months, and on as many as 3 occasions. Studies performed on the chromosomal changes that could be attributed to the radioactive material show the disappearance of these alterations a few years after treatment. No physical changes have been found that could be attributed to cytogenic alteration (hematologic or other) in any reported patients.

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.

Intra-articular hyaluronic acid in the treatment of haemophilic chronic arthropathy.

We report our preliminary experience with the use of hyaluronic acid (Synvisc) in 29 joints from 25 different haemophilic patients (17 knees, six shoulders, four ankles, one elbow and one hip). All the joints were grade III of our classification, characterized by synovial thickening, axial deformities and muscle atrophy (chronic arthropathy). In view of the very satisfactory results obtained with this procedure, we have substituted Synvisc for the previous use of intra-articular long-standing corticosteroids that we had been used for some years. This method is theoretically more physiological and does not destroy the joint cartilage further, as corticosteroids can.
