Use of a new, flexible lipidocolloid dressing on acute and chronic wounds: results of a clinical study.

OBJECTIVE: To document the performance (efficacy, tolerability and acceptability) of Urgotul Flex, a new, more flexible version of the lipidocolloid dressing Urgotul, in the management of acute and chronic wounds. Efficacy was defined as the reduction in ulcer surface area after 4 weeks of treatment. METHOD: This open, non-comparative, multicentre clinical trial recruited patients from 11 centres, which included surgical, burns and rehabilitation units and paediatric, geriatric and dermatology wards. Inclusion criteria were non-infected wounds of any aetiology that were <120cm2 in size. Ulcer surface area was assessed by tracing and planimetry. Acceptability parameters were: ease of dressing application; pain at dressing change; dressing adherence to wound bed and bleeding at removal; maceration of surrounding skin; these were all assessed qualitatively. Patients were followed up for a maximum of 4 weeks, or until they healed if this occurred first. Efficacy and tolerability were assessed by the physicians on a weekly basis, and acceptability by the nursing staff at each dressing change. All of the physicians/nurses had previously participated in clinical evaluations of Urgotul using the same outcomes and assessments, and so performed a retrospective assessment of the two dressings. RESULTS: Forty-four patients from 11 investigating centres were included in the study. The mean baseline surface area at was 21cm2 and 6cm2 for the acute and chronic wounds respectively. Twenty wounds (17 acute wounds and three chronic wounds) healed. Of the remainder, the mean surface area reduction was 78% and 42% for the acute and chronic wounds respectively at the end of the 4-week treatment period. Only two local adverse events were reported, but these were not considered to be dressing related. Based on the 345 documented dressing changes, conformability of the new dressing was considered to be superior to that of Urgotul, particularly when used on acute wounds. CONCLUSION: These findings show that the efficacy and tolerability of Urgotul Flex is similar to that reported in previous observational studies on Urgotul. However, results show it is more flexible and thus more conformable, particularly when used on wounds in awkward locations, including paediatric wounds and hand surgery. CONFLICT OF INTEREST: This evaluation was sponsored by Laboratoires URGO, Chenôve, France.

The sagittal anatomy of the sacrum among young adults, infants, and spondylolisthesis patients.

The anatomic pelvic parameter "incidence" - the angle between the line perpendicular to the middle of the sacral plate and the line joining the middle of the sacral plate to the center of the bicoxo-femoral axis - has been shown to be strongly correlated with the sacral slope and lumbar lordosis, and ensures the individual an economical standing position. It is important for determining the sagittal curve of the spine. The angle of incidence has also been shown to depend partly on the sagittal anatomy of sacrum, which is established in childhood while learning to stand and walk. The purpose of this study was (1) to define the relationship between the sacrum and the angle of incidence, and (2) to compare these parameters in three populations: young adults, infants before walking, and patients with spondylolisthesis. Forty-four normal young adults, 32 infants not yet walking and 39 patients with spondylolisthesis due to isthmic spondylolysis underwent a sagittal full-spine radiography. A graphic table and the software for bidimensional study of the sacrum developed by J. Hecquet were used to determine various anatomic and positional parameters. Comparison tests of means, and multiple and partial correlation tests were used. A study of the reliability of the measurements using factorial plan methods was performed. The sagittal anatomic parameters of the sacrum were found to have a close relationship with the pelvic parameter of incidence angle, and therefore with the sagittal balance of the spine. The anatomy of the sacrum in spondylolisthesis patients is particular in that some features are much like those of young infants, but it is more curved and the incidence angle is significantly larger. There is a close relationship between angle of incidence and the slip of spondylolisthesis. All the parameters of young infants are significantly smaller than those of adults. It can be concluded that the sagittal anatomy of the sacrum plays a key role in spinal sagittal balance. The sacral bone is an integral a part of the pelvis and constitutes the undistorted part of the spinal curves. Organization of sagittal curves during growth can be followed up by looking at the sacrum. The sacrum in the spondylolisthesis group differs from the normal, and the greater angle of incidence and sacral slope in this group could predispose to vertebral slip.

Inflammatory lesions of peripheral nerve in a patient with human T-lymphotropic virus type I--associated myelopathy.

In a patient with tropical spastic paraparesis associated with a positive titer for human T-lymphotropic virus type I, electrophysiological study detected a mixed, axonal and demyelinating, multifocal neuropathy. Perineural and perivascular infiltrates, moderate axon loss, wallerian degeneration, and demyelinating lesions of isolated fibers were present in the nerve biopsy specimen. These inflammatory lesions resembled those found in the central nervous system of patients with tropical spastic paraparesis.

[Myasthenia in children: long-term course]. / La myasthénie de l'enfant: évolution à long terme.

Twenty three children with myasthenia were followed up in our Department for 10 years. There were no familial forms of the disease; there were no patients with the pure ophthalmic form but 61 p. 100 of patients had serious respiratory disease. Steroid therapy was possible in 10 cases: in 4 patients under 15 years of age, short courses of steroids were ineffective; in 6 patients over the age of 15, long term steroid therapy resulted in some improvement but cortico-dependence developed in 4 cases. One child responded to treatment with veinoglobulin (R). Sixteen children underwent thymectomy; the symptoms in the 7 non-thymectomized patients were equivalent. The myasthenic syndrome was stable or worsened in 75 p. 100 of cases after thymectomy; only 56 p. 100 of children improved 2 years after surgery. The incidence of complete remission was the same in the children undergoing thymectomy and in those not treated surgically at 7 years after thymectomy. Our attitude is therefore not to refer myasthenic children for routine thymectomy and to avoid steroid therapy whenever possible.

[Gynecomastia in boys before puberty]. / Les gynécomasties du garçon avant la puberté.

Gynecomastia is seldom observed in prepubertal boys. Sixteen cases are reported in this work, 3 of them being related to a defect of 11 hydroxylase with virilizing adrenal hyperplasia and 13 being considered as idiopathic. These gynecomastias consist of a slight breast enlargement, often unilateral (10 of 16) and may spontaneously disappear after 3 to 12 months (5 of 16 cases). In the so-called idiopathic cases, the hormonal investigations performed gave normal results, so that no physiopathological explanation could be suggested.
