The traditional surgical treatment of severe spinal deformities, both in adult and pediatric patients, consisted of a 360° approach. Posterior-based spinal osteotomy has recently been reported as a useful and safe technique in maximizing kyphosis and/or kyphoscoliosis correction. It obviates the deleterious effects of an anterior approach and can increase the magnitude of correction both in the coronal and sagittal plane. There are few reports in the literature focusing on the surgical treatment of severe spinal deformities in large pediatric-only series (age <16 years old) by means of a posterior-based spinal osteotomy, with no consistent results on the use of a single posterior-based thoracic pedicle subtraction osteotomy in the treatment of such challenging group of patients. The purpose of the present study was to review our operative experience with pediatric patients undergoing a single level PSO for the correction of thoracic kyphosis/kyphoscoliosis in the region of the spinal cord (T12 and cephalad), and determine the safety and efficacy of posterior thoracic pedicle subtraction osteotomy (PSO) in the treatment of severe pediatric deformities. A retrospective review was performed on 12 consecutive pediatric patients (6 F, 6 M) treated by means of a posterior thoracic PSO between 2002 and 2006 in a single Institution. Average age at surgery was 12.6 years (range, 9-16), whereas the deformity was due to a severe juvenile idiopathic scoliosis in seven cases (average preoperative main thoracic 113°; 90-135); an infantile idiopathic scoliosis in two cases (preoperative main thoracic of 95° and 105°, respectively); a post-laminectomy kypho-scoliosis of 95° (for a intra-medullar ependimoma); an angular kypho-scoliosis due to a spondylo-epiphisary dysplasia (already operated on four times); and a sharp congenital kypho-scoliosis (already operated on by means of a anterior-posterior in situ fusion). In all patients a pedicle screws instrumentation was used, under continuous intra-operative neuromonitoring (SSEP, NMEP, EMG). At an average follow-up of 2.4 years (range, 2-6) the main thoracic curve showed a mean correction of 61°, or a 62.3% (range, 55-70%), with an average thoracic kyphosis of 38.5° (range, 30°-45°), for an overall correction of 65% (range, 60-72%). Mean estimated intra-operative blood loss accounted 19.3 cc/kg (range, 7.7-27.27). In a single case (a post-laminectomy kypho-scoliosis) a complete loss of NMEP occurred, promptly assessed by loosening of the initial correction, with a final negative wake-up test. No permanent neurologic damage, or instrumentation related complications, were observed. According to our experience, posterior-based thoracic pedicle subtraction osteotomies represent a valuable tool in the surgical treatment of severe pediatric spinal deformities, even in revision cases. A dramatic correction of both the coronal and sagittal profile may be achieved. Mandatory the use of a pedicle screws-only instrumentation and a continuous intra-operative neuromonitoring to obviate catastro...

Multiple myeloma (MM) is a B cell malignancy characterized by important alterations of physiologic bone turnover, wherein increased osteoclastic bone resorption is not accompanied by a comparable increase in bone formation, resulting in diffuse osteopenia, focal lytic lesions, pathologic fractures, hypercalcemia, and bony pain. Consequently, patients with MM frequently require for quality of life's improvement and pain's treatment radiation therapy, surgery, and analgesic medication. Minimally invasive surgical procedures such as the kyphoplasty allows patients with pathological osteolytic vertebral lesions to have immediate improvement in their quality of life. This surgical technique provides in myeloma vertebral collapses same quick pain relief as in osteoporotic vertebral fractures, and a minor morphological restoration of the interested vertebra, but sufficient to restore sagittal alignment. The aim of the study was to evaluate the functional and morphological results of kyphoplasty for the treatment of vertebral osteolysis due to MM. We report a retrospective study in 30 such patients (45 vertebral lesions) who were evaluated before and after kyphoplasty, with regard to pain, general condition, quality of life, use of analgesics, by means of evaluation forms: Short-Form-36, Visual Analog Scale, Oswestry Disability Index, and with regard to percentage height restored and reduction of segmental kyphosis. Marked clinical improvement was observed in all patients during the first 12 postoperative months, with gradual a little worsening thereafter from deterioration of their general condition to 60-month follow-up. The restoration of vertebral body mean height was maintained to 5 years clinical and radiographic control. Segmental kyphosis angle correction showed a mean decrease of 1.7 degrees (range 0 degrees -2.5 degrees ) at radiographic control at 5-year follow-up, with respect to the immediate postoperative X-ray, although lower than preoperative. The data obtained demonstrated the effectiveness of kyphoplasty in the treatment of vertebral collapse in MM. The results achieved with this minimally invasive technique were clinically and biomechanically satisfactory.

The modified S-plasty reconstruction can represent a valid alternative to elliptical excision if the lesion to be removed is sufficiently large and when a shorter and curved suture line is preferable.

Basal cell carcinoma (BCC) is a common skin cancer worldwide. However, BCC of the nipple and areola complex is rare. Men are more affected than women. Most of the cases were treated with simple excision. We report a case of BCC of the right nipple-areola complex in a 75-year-old man, treated with Mohs surgery and simple mastectomy.
