Chronic idiopathic hyperphosphatasia with unusual dental findings: a case report
2012
Chronic idiopathic hyperphosphatasia(CIH) or juvenile Paget disease is believed to be a distinct disease characterized by an increase in the serum alkaline phosphatase, cortical thickening and bowing of the long bones, especially the femora. It is a rare autosomal recessive bone disorder, with excessive bone resorption and bone formation. Skeletal malformations in the legs may cause problems in walking and may eventually result in short stature. The radiographic appearances include widening of the diaphyses, vertebral osteoporosis, acetabular protrusion, and thickening of the skull vault. Intensive bisphosphonate treatment prevented the development of deformity and disability but there is n…
Epigenetics in spine curvature disorders
2022
Abstract Scoliosis is a three-dimensional (3D) structural deformity of the spine with a radiological lateral Cobb angle of ≥ 10°. Several classification systems exist, dividing different types regarding the age of onset or the type of etiology. The minority of cases are secondary to congenital, syndromic of neuromosucular diseases. Most of the cases are classified “idiopathic” due to unknown etiology. These were formally divided by the age of onset into “Infantile Idiopathic Scoliosis” (0–3 years), “Juvenile Idiopathic Scoliosis” (JIS—4–10 years), and “Adolescent Idiopathic Scoliosis” (AIS → 10 years). Since the initiative of the Scoliosis Research Society in 2014 all kind of scoliosis with…
Intra- and Interrater Reliability of Sagittal Spinopelvic Parameters on Full-Spine Radiographs in Adults With Symptomatic Spinal Disorders
2018
Background/Aims To evaluate the intra- and interrater reliability (I-IR) of sagittal spinopelvic parameters from digital full-spine plain radiographs with basic software tools in an unselected adult population with degenerative spinal complaints who were evaluated for surgery. Methods Forty-nine adult full-spine digital radiographs were measured twice by 3 independent observers, including an experienced spine surgeon, an experienced radiologist, and a resident orthopedic surgeon. Clinical picture archiving and communication system workstations and software tools were used and landmarks were set manually. The I-IR of the sagittal vertical axis (SVA), pelvic tilt (PT), pelvic incidence (PI), …
Kyphoscoliotic Ventilatory Insufficiency
2003
Objectives: To determine the effects of long-term nocturnal intermittent positive-pressure ventilation (NIPPV) on symptoms, pulmonary function test results, sleep, and respiratory muscle performance in patients with ventilatory insufficiency due to severe kyphoscoliosis. Design: A prospective study in which 16 severe kyphoscoliotic patients were treated with NIPPV delivered by volume-cycled and pressure-cycled ventilators, over a period of 36 months. Interventions and measurements: At baseline, pulmonary function tests, blood gas measurements, polysomnography, and respiratory muscle strength (measured by noninvasive indexes) were obtained. Symptoms and the number of hospitalizations in the …
Back Pain Characteristics in Physical and Office Workers
2018
The aim of our study was to characterize back pain according to the occupation comprising physical and office work. Accordingly questionnaires from 100 physical workers (PW) and 100 office workers (OW) were collected. This dedicated questionnaire included 19 questions, of which 7 concerned demographic, work and stature features and 12 concerned back pain. Collected data showed that lower back pain was more common in PW but cervical pain in OW (p0.001). Most common aetiology of back pain was spinal osteoarthritis, sciatica and scoliosis but of different spread in two groups (p0.001). The history of back pain was most often above 5 years and there were significant differences in frequency,…
Pulmonary hypertension caused by a severe scoliosis
1996
Background. Pulmonary hypertension in childhood is uncommon. It can be idiopathic or secondary to other pathologies (cardiovascular, skeletric,...). Case description. We report on a 9 year old girl suffering from pulmonary hypertension due to severe dorso-lumbar scoliosis. Conclusions. We discuss the etiopathogenetic relationship between scoliosis and pulmonary hypertension, with particular reference to the role of the treatment with Milwaukee's corset in the evolution of the disease.
Is there a relationship between idiopathic scoliosis and body 2 mass? A scoping review
2022
The etiopathogenesis of idiopathic scoliosis remains unknown, although genetic or hered- 12 itary factors, neurological disorders, hormonal and metabolic dysfunctions, biomechanical factors, 13 and environmental factors seem to be involved. Several studies have found that patients with scoli- 14 osis have common characteristics of taller stature, lower body mass index (BMI), and low systemic 15 bone mass. We conducted a scoping review to analyze the association between idiopathic scoliosis 16 and BMI. The search for articles was performed on PubMed and Cochrane, including the English 17 language, full-text and free-full-text articles published from December 31st, 2011 to December 31st, 18 2…

Geometric Properties of the 3D Spine Curve
2003
Through a 3D reconstruction of the human back surface using structured light techniques, we study the properties of spine curve by means of a set of parameters related to measures commonly applied in medicine. In this way, descriptors for measuring the abnormalities in the projections of the front and sagittal planes can be computed. We build the spine curve in 3D and analyse the behaviour of the Frenet frame when along the curve the deformation processes in idiophatic scoliosis appear.
Determination of the object surface function by structured light: application to the study of spinal deformities.
1999
The projection of structured light is a technique frequently used to determine the surface shape of an object. In this paper, a new procedure is described that efficiently resolves the correspondence between the knots of the projected grid and those obtained on the object when the projection is made. The method is based on the use of three images of the projected grid. In two of them the grid is projected over a flat surface placed, respectively, before and behind the object; both images are used for calibration. In the third image the grid is projected over the object. It is not reliant on accurate determination of the camera and projector pair relative to the grid and object. Once the met…
