OBJECTIVES: Low back pain (LBP) is the most commonly reported chronic pain condition. In this study, a clinically relevant, induced-LBP paradigm was used to study sensory processing as a risk factor and predictor for LBP development in healthy people. Our aim was to examine sensory processing in those who do develop LBP and those who do not develop LBP with the paradigm, and to examine the relationships between scores on psychosocial questionnaires and sensory processing measures in these healthy people...

Upright stance in humans requires an intricate exchange between the neural mechanisms that control balance and those that control posture; however, the distinction between these control systems is hard to discern in healthy subjects. By studying balance and postural control of a participant with camptocormia - an involuntary flexion of the trunk during standing that resolves when supine - a divergence between balance and postural control was revealed. A kinematic and kinetic investigation of standing and walking showed a stereotyped flexion of the upper body by almost 80 degrees over a few minutes, and yet the participant's ability to control their center of mass within their base of support and to compensate for external perturbations remained intact...

A 67-year-old man with poorly controlled type II diabetes mellitus was evaluated for right lower extremity erythema and swelling and left-sided lower back pain. He was found to have Pasteurella multocida bacteremia; magnetic resonance imaging showed osteomyelitis of the lumbar spine with myositis in the adjacent left paraspinal muscles. He was initially treated with intravenous antibiotics and was later transitioned to oral amoxicillin. He recovered completely with six weeks of antimicrobial therapy.

BACKGROUND: Bertolotti's syndrome is a spinal disorder characterized by abnormal enlargement of the transverse process of the most caudal lumbar vertebra. The L5 transverse process may be enlarged either unilaterally or bilaterally and may articulate or fuse with the sacrum or ilium. Pseudoarticulation between the transverse process of the L5 and the alar of the sacrum can cause buttock pain and leg pain. In addition, the L4 exiting nerve root could be compressed by an enlarged L5 transverse process...

Malignant peripheral nerve sheath tumors (MPNST) are very rare and are frequently localized in the buttocks, thigh, arm, or paraspinal region; one variant is the malignant Triton tumor, with rhabdomyosarcomatous differentiation. The authors present a challenging differential diagnosis of a sciatic pain and foot drop in a woman with history of lumbar disk herniation, which was found to be caused by a Triton tumor of the sciatic nerve. She underwent surgical excision, followed by radiation and chemotherapy. Malignant Triton tumor cases have rarely been described and reported in the literature...

We describe the case of a 71-year-old man with a ganglioneuroma of the retropharyngeal space. The patient presented with a submucosal bulge of the left oropharyngeal wall during follow-up examination of a treated vocal cord carcinoma. CT and MRI revealed a non-specific, well-defined retropharyngeal soft tissue lesion. Positron emission tomography-CT did not show relevant metabolic activity, excluding the hypothesis of metastatic nodal disease. Surgical biopsy of the lesion was compatible with ganglioneuroma...

INTRODUCTION: A calpain-3 (CAPN3) gene heterozygous deletion (c.643_663del21) was recently linked to autosomal dominant (AD) limb girdle muscular dystrophy. However, the possibility of digenic disease was raised. We describe three families with AD calpainopathy carrying this isolated mutation. METHODS: Probands heterozygous for CAPN3 c.643_663del21 were identified by targeted next generation or whole exome sequencing. Clinical findings were collected for probands and families...

Infantile fibrosarcomas (IFS) represent a distinct group of soft tissue tumors occurring in patients under 2 years of age and most commonly involving the extremities. Most IFS show recurrent ETV6-NTRK3 gene fusions, sensitivity to chemotherapy, and an overall favorable clinical outcome. However, outside these well-defined pathologic features, no studies have investigated IFS lacking ETV6-NTRK3 fusions, or tumors with the morphology resembling IFS in older children. This study was triggered by the identification of a novel SEPT7-BRAF fusion in an unclassified retroperitoneal spindle cell sarcoma in a 16-year-old female by targeted RNA sequencing...

BACKGROUND: Knee osteoarthritis (OA) is an increasing health problem worldwide. So far, only obesity and quadriceps weakness are identified as modifiable risk factors for knee OA. Core muscle strengthening is becoming increasingly popular among older adults because of its ability to enhance the activities of daily living during old age. This study investigated the associations of the size and quality of the abdominal trunk muscles with radiographic knee osteoarthritis (RKOA). METHODS: From 2012 to 2016, data were collected from 146 males and 135 females (age 63...
