Optic neuropathy associated with laser in situ keratomileusis.

Abstract: Purpose To report 4 cases of optic neuropathy following laser in situ keratomileusis (LASIK). Setting Tertiary care ophthalmic practices. Methods In this retrospective observational case series, 4 patients who developed acute visual loss following LASIK are reported. All had clinical evidence of optic neuropathy. Two had optic disc edema and 2 had normal appearing optic discs initially. None of the patients experienced significant visual recovery, and all developed optic atrophy in the affected eye. Results All patients had evaluations for alternative etiologies of their optic neuropathy, with negative results. All patients were therefore presumed to have experienced an ischemic optic neuropathy following LASIK. Conclusions Patients who have LASIK may experience an acute anterior or retrobulbar optic neuropathy. The etiology is unknown but may be related to the marked increase in intraocular pressure that occurs during a portion of the procedure.

The Role of Extracorporeal Shockwave Treatment in Musculoskeletal Disorders.

Abstract: Increasing evidence suggests that extracorporeal shockwave treatment (ESWT) is safe and effective for treating several musculoskeletal disorders.Two types of technical principles are usually included in ESWT: focused ESWT (F-ESWT) and radial pressure waves (RPW). These 2 technologies differ with res

The principle of helical implants. Unusual ideas worth considering.

Abstract: The clinical use of helical implants (implants extruded over helical paths either periosteal (plates / internal fixators) or intramedullary implants for bone fixation is presented. A helical nail permits more degrees of freedom when choosing an entry point. With a helical periosteal device it is possible to position an implant on different aspects of bone (for instance, laterally in the proximal part of the bone or anteriorly in the distal part of the bone). These options have proven particularly useful when attempting to avoid damage to the vascular system of the femoral head and when performing MIPO bridge plating of humeral shaft fractures. Helical implants open up a new and still unexplored field in bone fixation. Early results have been very encouraging. It is hoped that indications for its use will broaden once the international community of orthopaedic surgeons realizes its existence and its major innovative features.

A simplified lesion classification for predicting success and complications of coronary angioplasty

Abstract: In 1988, the American College of Cardiology/American Heart Association (ACC/AHA) Task Force on Assessment of Diagnostic and Therapeutic Cardiovascular Procedures presented a classification of coronary lesions utilizing 26 lesion features to predict the success and complications of balloon angioplasty. Using data from the Registry of the Society for Cardiac Angiography and Interventions (SCAI) we evaluated the ability of this classification to predict success and complications. Lesion success, death in hospital, emergency cardiac bypass surgery, and major adverse events were evaluated in 41,071 patients who underwent single-vessel angioplasty from January 1993 to June 1996. Logistic models using the ACC/AHA lesion classification, vessel patency, or both, were compared. A new classification based on the interaction of the ACC/AHA classification plus lesion patency was compared with the existing ACC/AHA classification. Vessel patency, added to the ACC/AHA classification, improved prediction of lesion success (p ≤0.0001). Class A and patent B lesions had similar success and complication rates, so a simplified classification (SCAI) using only 7 lesion characteristics could be created. This system (I: non-C patent, II: C patent, III: non-C occluded, and IV: C occluded) improved prediction of lesion success compared with the ACC/AHA classification (Bayesian Information Criterion statistic: ACC/AHA 16539, SCAI 15956; and area under the receiver- operating characteristics curve 0.659, 0.693, respectively). The SCAI classification was preferred for predicting major complications and in-hospital death and was similar to the ACC/AHA classification for predicting emergency bypass surgery.
