Spondylolysis is a major cause of back pain in children and adolescents. The prevalence of spondylolysis depends on the sex, race, and congenital abnormality. These biases suggest hereditary predisposition as an etiology of spondylolysis. However, no conclusive evidence still exists regarding the inheritance for spondylolysis. Herein, we report rare cases with familial occurrence of lumbar spondylolysis. In two generations of a Japanese family, three brothers including identical twins complained of back pain related to sports activities...

INTRODUCTION: Musculoskeletal symptoms related to using traditional computer workstations are common. To improve ergonomics of workstations quantitative methods for measuring muscle stress and strain are needed. We hypothesize that infrared thermography (IRT) is suited for this purpose. METHODS: This hypothesis was evaluated by estimating muscle activity in upright and traditional working postures with IRT and surface electromyography (sEMG). IRT and sEMG measurements were conducted in 14 female participants with both working postures...

Histoplasmosis is an infection caused by a fungus called Histoplasma. Diagnosis of histoplasmosis is based on the culture of biological samples and detection of fungus in tissues. Histoplasmosis can mimic malignant lesions. We report a 65-year-old, immunocompetent, male patient with back pain. We describe the main clinical and radiological characteristics in our patient who had vertebral histoplasmosis that mimicked cancer. A computed tomography scan showed lytic lesions of the right side of T4, T5, and T6 vertebral bodies...

Maximum muscle stress (MMS) is a critical parameter in musculoskeletal modeling, defining the maximum force that a muscle of given size can produce. However, a wide range of MMS values have been reported in literature, and few studies have estimated MMS in trunk muscles. Due to widespread use of musculoskeletal models in studies of the spine and trunk, there is a need to determine reasonable magnitude and range of trunk MMS. We measured trunk extension strength in 49 participants over 65 years of age, surveyed participants about low back pain, and acquired quantitative computed tomography (QCT) scans of their lumbar spines...

BACKGROUND: Low back pain (LBP) is a major problem for office workers. Individuals adopting poor postures during prolonged sitting have a considerably increased risk of experiencing LBP. This study aimed to investigate seat pressure distribution characteristics, i.e., average pressure, peak pressure ratio, frequency of postural shift, and body perceived discomfort (BPD), during 1 hour of sitting among office workers with and without chronic LBP. METHODS: Forty-six participants (chronic LBP = 23, control = 23) typed a standardized text passage at a computer work station for an hour...

Granulomatosis with polyangiitis (GPA) is a systemic disease characterized by necrotizing, granulomatous vasculitis of the upper and lower respiratory tracts and glomerulonephritis, and is classified as a classical or limited form. The classical form of GPA demonstrates the involvement of the upper respiratory tract, sinuses, lungs and kidneys, whereas the limited form is characterized by the lack of the renal involvement with female predominance. On the other hand, mixed connective tissue disease (MCTD) shows the clinical and laboratorial features of systemic lupus erythematosus, systemic sclerosis and polymyositis, along with high titers of anti-ribonucleoprotein antibodies and is characterized by good response to corticosteroid therapy and favorable prognosis...

Damage at the intervertebral disc-vertebra interface associates with back pain and disc herniation. However, the structural and biomechanical properties of the disc-vertebra interface remain underexplored. We sought to measure mechanical properties and failure mechanisms, quantify architectural features, and assess structure-function relationships at this vulnerable location. Vertebra-disc-vertebra specimens from human cadaver thoracic spines were scanned with micro-computed tomography (μCT), surface speckle-coated, and loaded to failure in uniaxial tension...

Facet joint osteoarthritis is considered a consequence of the aging process; however, there is evidence that it may be associated with degenerative changes of other structures. The goal of this study was to investigate the correlation between lumbar multifidus muscle features and facet joint osteoarthritis. This retrospective study included 160 patients who had acute or chronic low back pain and were diagnosed with facet joint osteoarthritis on computed tomography scan. Morphometric parameters, including cross-sectional area, muscle-fat index, and percentage of bilateral multifidus asymmetry at L3-L4, L4-L5, and L5-S1, were evaluated with T2-weighted magnetic resonance imaging...

The main reason for waist and back pain in patients with gigantomasty is increased thoracic kyphosis and lumber lordosis. These symptoms and abnormal spinal angulations regress after reduction mammoplasty operations. However, the effect of chronic mechanical stress caused by gigantomasty on the spinal degenerative process is not clear yet. In this study with computed tomography it is shown that degenerative spondylosis is more widespread and severe in patients with large breasts.

Endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) is of limited usefulness for diagnosing thyroid disease, and few studies have reported its use in diagnosing and treating thyroid cysts. The present study investigated a unique case of diagnosis and treatment of a thyroid cyst by EBUS-TBNA. A 67-year-old male presented with back pain. Positron emission tomography/computed tomography scanning revealed low-density signals in the right lobe of the thyroid. Needle aspiration biopsies and drainage at this site was performed, and EBUS was used for guidance in diagnosing the thyroid cyst...

Thoracic endovascular aortic repair (TEVAR) has been reported to be an effective treatment option for aortic emergencies. However, there are few reports about TEVAR for aortic rupture due to radiation injury. A 54-year-old man presented with haemoptysis. He had a history of lung cancer, which had been treated with chemotherapy and radiation therapy (72 Gy/16 times) 3 years previously, and the cancer lesion did not progress. On chest radiography, pneumonia was suspected in the radiated lesion. However, after admission, he presented with back pain, progressive anaemia and hypotension...
