To evaluate the effects of nicorandil in a rat kidney model of partial unilateral ureteral obstruction (PUUO). Thirty male rats were randomly divided into three groups as follows: (1) Group 1 (Sham-control), ureters of the rats were manipulated but not ligated; (2) Group 2 (PUUO-untreated), PUUO was performed with two-thirds of the left ureter embedded in the psoas muscle; and (3) Group 3 (PUUO-nicorandil treated). After PUUO was established, nicorandil (15 mg/kg/day) was administered by gastric lavage for 21 days to determine its effects on PUUO-induced histopathological-, functional-, and oxidative stress-induced changes...

BACKGROUND: Laparoscopic ventral mesh rectopexy for rectal prolapse has been widely used over the past decade to reduce postoperative functional bowel disorders. We aimed to compare changes in functional outcome 12 months after laparoscopic ventral mesh rectopexy versus laparoscopic posterior sutured rectopexy in patients with rectal prolapse. METHODS: In this double-blind, randomised trial, consecutive patients aged 18 years or older at a single centre in Denmark with full-thickness rectal prolapse were randomly assigned (1:1) to either laparoscopic ventral mesh rectopexy or laparoscopic posterior sutured rectopexy by drawing numbers from opaque envelopes, in blocks of four for patients with or without preoperative constipation...

In its typical form, spinal tuberculosis (TB) presents as destroyed contiguous vertebral bodies with involvement of intervertebral discs and paravertebral or psoas abscesses. Atypical forms are uncommonly reported. Here, we describe 8 patients with noncontiguous multisegmental spinal TB with no intervertebral disc involvement. From 2013 to 2014, we surgically treated 384 patients with spinal TB to relieve spinal cord compression, re-establish spinal stability, confirm the diagnosis, and debride the TB foci...

OBJECTIVE: Spinal epidural abscess (SEA) is a serious infection requiring prompt treatment and potential neurosurgical intervention. Although contrast-enhanced spine MRI is the mainstay for diagnosis of SEA, unenhanced MRI is typically performed for patients with nonspecific symptoms or insufficient clinical information. We evaluated the sensitivity and specificity of imaging features suggestive of SEA at unenhanced spine MRI. MATERIALS AND METHODS: We searched our database for contrast-enhanced lumbar spine MRI examinations from January 1, 2000, through August 1, 2014, with "epidural abscess" in the report...

Malignant psoas syndrome is a rare malignant condition presenting as lumbosacral plexopathy and painful fixed flexion of the hip. Metastasis to the psoas muscle is observed, which damages the nerve bundles in the lumbosacral plexuses. The syndrome presents as refractory lower back pain with several other neurological symptoms. The pain is difficult to control because it is a mixture of nociceptive and neuropathic pain, which indicates that treatment requires a versatile approach. The authors report a case of severe back pain caused by metastasis to the psoas muscle of advanced gastric cancer in a patient who underwent palliative radiotherapy under epidural analgesia...

Label-free strategy was applied to elucidate muscle-specific beef (M. longissimuss lumborum (LL) and M. psoas major (PM)) color stability of Holstein cattle during post-mortem storage at 4°C±1°C. LL showed greater (p<0.05) redness (a(∗)) value than PM at day 4 and 9 storage, while the proportion of metmyoglobin in PM exhibited a greater increase than in LL muscle. Furthermore, an overabundance of proteins with the functions of antioxidation, protection, and repair in LL were conducive to its color stability, whereas the overabundant proteins/subunits involved in tricarboxylic acid (TCA) cycle and mitochondrial electron transport chain (ETC) in PM indicated greater oxidative metabolism and degradation of ETC complexes, resulting in poor color stability...

OBJECTIVES: The purpose of this study was to identify the cut-off value of sarcopenia based on the psoas muscle area index and evaluate early and late outcomes following elective total arch replacement in the elderly. METHODS: Sarcopenia was assessed by the psoas muscle area index [defined as the psoas muscle area at the L3 level on computed tomography (cm 2 )/body surface area (m 2 )]. The cut-off value for sarcopenia was defined as > 2 standard deviations below the mean psoas muscle area index value obtained from 464 normal control patients...

Maja Babic, Claus S Simpfendorfer
Pyogenic infections of the bony spinal column and the intervertebral discs are on a steady rise in an aging western population. Despite advanced medical imaging, this clinical entity of devastating consequences if missed, still presents a diagnostic conundrum and is plagued by an unacceptably long diagnostic delay. The aim of this article is to raise awareness of the heterogeneity of spinal infections paralleling the complex structure of the spinal column and neighboring soft tissues. Emphasis is placed on the clinical presentation and management of septic facet joints and psoas muscle abscesses associated with lumbar spondylodiscitis...

BACKGROUND CONTEXT: Injuries to the lumbar plexus during lateral approaches to the spine are not uncommon and may result in permanent deficits. However, the literature contains few studies that provide landmarks for avoiding the branches of the lumbar plexus. PURPOSE: The present anatomical study was performed to elucidate the course of these nerves in relation to lateral approaches to the lumbar spine. STUDY DESIGN: This is a quantitative anatomical cadaveric study...

Malignant psoas syndrome (MPS) is an uncommon condition first described by Stevens et al. MPS is caused by malignant infiltration of the psoas muscle and adjacent nerves and is characterised by (fixed) flexion deformity of the ipsilateral hip and proximal lumbosacral plexopathy. It has previously been described in relation to metastatic carcinoma, melanoma and liposarcoma, as well as non-Hodgkins lymphoma. We present the case of a 68-year-old woman with a sarcoma arising in the left psoas muscle at the level of L4 who presented with symptoms of MPS...

Purpose: Aim of our study was to evaluate the effect of stepwise reduced doses on objective and subjective image parameters and on oncologic readings in whole-body (18)F-FDG-PET/MRI. Material and Methods: We retrospectively simulated the stepwise reduction of (18)F-FDG doses of 19 patients (50.9 ± 11.7 y/o, Body-Mass-Index (BMI) 22.8 ± 3.2) who received a whole-body PET/MRI examination from 3 to 0.5 MBq/kgBW in intervals of 0.25. Objective imaging parameters were assessed by measuring the standardized uptake value (SUV) and coefficient of variation (CV) in different regions (aorta, liver, spleen, kidney, small bowel, lumbar vertebra, psoas muscle, urinary bladder) as well as the noise equivalent count rates (NECR) in each bed position...

BACKGROUND: Although the significance of preoperative nutritional status has been investigated, there is no report regarding the relationship of their postoperative changes on outcomes in patients who underwent radical cystectomy for bladder cancer. Here, we report the clinical impact of the change, from baseline, in nutritional status and volume of abdominal skeletal muscle mass and adipose tissue after radical cystetomy. METHODS: A retrospective analysis of 89 patients with bladder cancer, who underwent curative radical cystectomy, was conducted to assess the time course of change, from baseline, in body composition and nutritional status at 1, 3, 6, 12, and 24 months, after surgery...

We aimed to determine whether comprehensive imaging analysis with analytic morphomics (AM) enhances or replaces geriatric assessment (GA) in risk-stratifying pancreatic surgery patients. One hundred thirty-four pancreatic surgery patients were identified from a prospective cohort. Sixty-three patients in the cohort had preoperative CT scans in addition to comprehensive geriatric assessments. CT scans were processed using AM. Associations with National Surgical Quality Improvement Program (NSQIP) serious complications were evaluated using univariate analysis and robust elastic net modeling to obtain AUROC curves by adding AM and GA measures to our previously defined clinical base risk model (age, body mass index, American Society of Anesthesiologists classification, and Charlson comorbidity index)...

We present a 49 year old man who presented to the emergency department with severe lower back pain of 5 days duration. One week prior he had been diagnosed with a right psoas muscle abscess and was discharged with a 28 day course of moxifloxacin after the preliminary culture from the psoas grew an anaerobic organism. MRI of the lumbar spine showed marrow edema in the L2 body, occupying most of the anterior two thirds of the body, with cortical erosion at the anteroinferior aspect of L1. Blood cultures were negative and bone biopsy of L2 showed neutrophilic invasion and reactive changes...

Hip flexion weakness is relatively common after lateral transpsoas surgery. Persistent weakness may result from injury to the innervation of the psoas major muscles (PMMs); however, anatomical texts have conflicting descriptions of this innervation, and the branching pattern of the nerves within the psoas major, particularly relative to vertebral anatomy, has not been described. The authors dissected human cadavers to describe the branching pattern of nerves supplying the PMMs. Sixteen embalmed cadavers were dissected, and the fine branching pattern of the innervation to the PMM was studied in 24 specimens...

The identification of a dysferlin-deficient animal model that accurately displays both the physiological and behavior aspects of human dysferlinopathy is critical for the evaluation of potential therapeutics. Disease progression in dysferlin-deficient mice is relatively mild, compared to the debilitating human disease which manifests in impairment of particular motor functions. Since there are no other known models of dysferlinopathy in other species, locomotor proficiency and muscular anatomy through MRI (both lower leg and hip region) were evaluated in dysferlin-deficient B6...

An 84-year-old Japanese man taking warfarin to prevent cerebral infarction secondary to atrial fibrillation was admitted to our hospital for evaluation of a painless right back mass. Magnetic resonance imaging (MRI) showed an oval-shaped mass in the right psoas major muscle. The mass showed high intensity on T1-, T2-, and diffusion-weighted imaging and mimicked an acute-phase hematoma. However, it showed no chronological changes typical of a hematoma, and MRI revealed enlargement of the mass 1 week after admission...

BACKGROUND: Protein oxidation is widespread in biochemical systems. The objective of the study was to investigate the differences in protein oxidation, μ-calpain activity, desmin proteolysis and protein solubility of beef psoas major (PM) and semimembranosus (SM) muscles under three packaging systems during postmortem aging. At 24 h postmortem, beef muscles were packaged respectively in air-permeable film overwrap (AP), vacuum pack (VP) or modified atmosphere (MAP, 80% O2 + 20% CO2 ), and then displayed for 10 days (d) at 4 °C...

Asymptomatic spontaneous nephrocutaneous fistula is a rare and severe complication of chronic urolithiasis. We report a case of 56-year-old woman with a nephrocutaneous fistula (NFC) which developed from a superinfected urinoma following calyceal rupture due to an obstructing calculus in the left ureter. The patient was clinically asymptomatic and came to the emergency department for a painless left flank fluctuating mass. This urinoma was superinfected, with a delayed development of renal abscesses and perirenal phlegmon found on contrast-enhanced uro-computed tomography (CT), responsible for left renal vein thrombophlebitis and left psoas abscess...
