Background The Boesch technique 1 , 2 is a minimally-invasive and time-saving subcutaneous subcapital metatarsal osteotomy. Since 1984, we have been using this osteotomy technique for patients with a symptomatic tailor's bunion in whom conservative treatment has failed. This distal osteotomy is stabilized by a combination of a Kirschner wire and a special dressing. The results of this technique in patients with symptomatic tailor's bunion were reviewed. Methods Between March, 1998, and June, 2002, surgery was done in 77 feet of 65 patients with a mean age of 64.6 years. The mean followup was 56.6 (range 14 to 79) months. The 100-point American Orthopaedic foot and Ankle Society (AOFAS) Lesser Metatarsophalangeal-Interphalangeal Scale was used for scoring. Results 86.4% of 57 patients (66 feet) were free of pain at final followup. The mean 4–5 intermetatarsal angle was 12 degrees before and 8 degrees after surgery. The mean lateral deviation of the fifth metatarsal was 5.7 degrees before and 5.1 degrees after surgery. The mean fifth metatarsophalangeal angle was 17.8 degrees before and 6.2 degrees after surgery. The mean preoperative 100-point AOFAS score was 59.1 (range 23 to 88) and the postoperative score, 95.2 (range 73 to 100). The overall results were excellent in 87.9%, (58 feet) good in 6.1% (4 feet), and satisfactory in 6.1%; none was poor. Conclusions The advantages of the subcutaneous subcapital Boesch technique are that it is time saving, it causes less bone and soft-tissue trauma, and it is performed under local anesthesia without a tourniquet. It is an effective operative option for symptomatic tailor's bunion; excellent and good clinical and radiographic results were found in 86.4% (57 patients, 66 feet) of the patients.

Techniques for three-dimensional reconstruction of macromolecular complexes from electron micrographs have been successfully used for many years. These include methods which take advantage of the natural symmetry properties of the structure (for example helical or icosahedral) as well as those that use single axis or other tilting geometries to reconstruct from a set of projection images. These techniques have traditionally relied on a very experienced operator to manually perform the often numerous and time consuming steps required to obtain the final reconstruction. While the guidance and oversight of an experienced and critical operator will always be an essential component of these techniques, recent advances in computer technology, microprocessor controlled microscopes and the availability of high quality CCD cameras have provided the means to automate many of the individual steps.During the acquisition of data automation provides benefits not only in terms of convenience and time saving but also in circumstances where manual procedures limit the quality of the final reconstruction.

Abstract. The present study aimed at evaluating if the three-item sense of coherence (SOC) scale developed by Lundberg and Nystrom Peck (1995) can be effectively used for research purpose in both nonclinical and clinical samples. To provide evidence that it represents adequately the measured construct we tested its validity in a nonclinical (N = 658) and clinical sample (N = 764 patients with cancer). Results obtained in the nonclinical sample attested a positive relation of SOC – as measured by the three-item SOC scale – with Antonovsky’s 13-item and 29-item SOC scales (convergent validity), and with dispositional optimism, sense of mastery, anxiety, and depression symptoms (concurrent validity). Results obtained in the clinical sample confirmed the criterion validity of the scale attesting the positive role of SOC – as measured by the three-item SOC scale – on the person’s capacity to respond to illness and treatment. The current study provides evidence that the three-item SOC scale is a valid, low-loading, and time-saving instrument for research purposes on large sample.
