BACKGROUND Reduced bone mineral density (BMD) is commonly found in alcohol-dependent patients. Many risk factors have been reported, yet the course of markers of bone formation and resorption in abstinent alcoholic patients have not received much attention. METHODS In a prospective longitudinal study, we investigated BMD in male abstinent inpatients of an alcohol rehabilitation clinic aged 21...

BACKGROUND Pregnancy and lactation in adolescents with habitually low calcium intake may adversely affect maternal bone mass. OBJECTIVE We investigated the effect of calcium plus vitamin D supplementation during pregnancy on bone mass during lactation in Brazilian adolescent mothers with low-calcium diets (∼600 mg/d). DESIGN Pregnant adolescents (14-19 y) randomly received daily calcium (60...

Background & Aims: The purpose of the present research was to compare the bone mineral density (BMD) of lumbar spine between athletic and non-athletic premenopausal women. Methods: Fifteen female athletes (runner) with the mean age of 33.80 ± 4.81 years, mean height of 164.13 ± 5.31 cm, mean weight of 57.33 ± 4.22 kg, and mean body mass index (BMI) of 21.41 ± 2.21 kg/m2 and 15 female non-athlet...

BACKGROUND AND PURPOSE Physical therapists commonly attempt to reduce and prevent low back pain by "improving" individuals' lumbar posture. To investigate the physical therapy clinical practice of attempting to "improve" lumbar posture, measures of passive tissue stiffness and angular deformation during activities of daily living were used. PARTICIPANTS The lumbar spine posture of 150 univers...

OBJECTIVES To describe the distribution of prevalent syndesmophytes and bridges, and the occurrence of new ones in a prevalence cohort of patients with AS. METHODS Clinical and radiological data from 132 patients from the Outcome in Ankylosing Spondylitis International Study of which complete sets of radiographs were available at baseline and at 2- and 4-year follow-up were used. RESULTS At...

This article presents the evolution in medical history which leads to the surgical treatment for ruptured discs. Only at the last century the precise diagnosis of a ruptured lumbar disc could be made after tremendous efforts of the many medical pioneers in the study of the spine. The experience gained with the lumbar spine was rapidly transferred to the cervical spine. We describe the evolution...

Astronauts experience spine deconditioning during exposure to microgravity due to the lack of axial loads on the spine. Treadmill exercise in a lower body negative pressure (LBNP) chamber provides axial loads on the lumbar spine. We hypothesize that daily supine LBNP exercise helps counteract lumbar spine deconditioning during 28 days of microgravity simulated by bed rest. Twelve sets of health...

Radiologists are often plagued by limited time for completing their work, with an ever increasing workload [31]. A picture archiving and communication system (PACS) is a platform for daily image reviewing that improves their work environment, and on that platform for example spinal MR images can be reviewed. When reviewing spinal images a radiologist wants vertebrae labels, and in Sectra’s PACS...
