The present study aimed to examine the influence of lateral dominance for ball kicking on the cross-sectional areas (CSAs) of thigh and trunk muscles in Japanese elite youth and professional soccer players, and to clarify the difference between the 2 groups in the muscle CSAs of the 2 body segments in relation to that in lean body mass (LBM). The CSAs of 4 (rectus abdominis, oblique, psoas majo...

Patients with cirrhosis have increased gluconeogenesis and fatty acid oxidation that may contribute to a low respiratory quotient (RQ), and this may be linked to sarcopenia and metabolic decompensation when these patients are hospitalized. Therefore, we conducted a prospective study to measure RQ and its impact on skeletal muscle mass, survival, and related complications in hospitalized cirrhot...

The human immunodeficiency virus (HIV)-lipodystrophy syndrome is characterized by abnormalities of lipid metabolism, glucose homeostasis, and fat distribution. Overaccumulation of intramuscular lipid may contribute to insulin resistance in this population. We examined 63 men: HIV positive with lipodystrophy (n = 22), HIV positive without lipodystrophy (n = 20), and age- and body mass index-matc...

Objective: The purpose of the present study was to determine relationship between psoas muscle lipoatrophy and facet disc degeneration in patients
 with low back pain lumbar spinal Magnetic Resonance Imaging (MRI).
 Material Methods: A total 304 patients who had were included this retrospective cross-sectional study. MRIs all evaluated for signs atrophy. Fat content each graded semi-q...

We report three cases of primary psoas muscle abscess. Two of these cases were treated by open drainage through a lumbar incision and the other was by ultrasonography (USG)-guided percutaneous aspiration of the abscess. Antibiotic therapy was also instituted in all cases. Post-operatively, the patients recovered well with no sign of recurrence. USG-guided percutaneous drainage combined with app...

Tuberculosis is an ancient disease. Skeletal system involvement is seen in 1%-10% tuberculosis patients. Vertebral tuberculosis is the most common form of bone involvement and amounts for 50% cases of skeletal tuberculosis. About 5% cases of Pott’s disease develop psoas abscess. Psoas abscess secondary to Pott’s spine is rare entity. Here we are reporting a case of psoas abscess secondary to Po...

The objective of this experiment was to determine the effect of sarcomere length on postmortem proteolysis and meat tenderness. Eighteen Dorset market-weight sheep were slaughtered conventionally. The longissimus thoracis et lumborum and psoas major from each carcass were either left intact on the carcass (control), which was chilled at 0 degrees C, or excised from the carcass and chilled in an...

Psoas abscess is a pus collection within the muscle compartment. It is a very uncommon entity. It can be primary as a result of haematogenous spread or secondary as a consequence of a direct extension of an infectious focus. Diagnosis is usually delayed because nonspecific clinical presentation. Staphylococcus aureus is the most common organism cultured in this type of abscess. We describe a se...

The present study reported the case of a patient with primary anaplastic large cell lymphoma (ALCL) occurring in the left major psoas. A 24-year-old male patient presented with one-month history of left lower back pain, which had been exacerbated for 10 days prior to admission. Magnetic resonance imaging (MRI) scans revealed an enlarged major psoas muscle that protruded into the inguinal region...

Pneumothorax secondary to septic pulmonary embolism (SPE) is rare but life-threatening. We herein report a long-term hemodialysis patient with psoas abscess caused by methicillin-resistant Staphylococcus aureus, associated with other muscle and splenic abscesses and SPE. Intravenous vancomycin treatment and percutaneous drainage of the psoas abscess rapidly improved her condition. However, the ...
