Lumbar intervertebral discs and paraspinal muscles in 74 healthy volunteers ranging in age from 19 to 74 years were evaluated with MRI, and the occurrence of degeneration was correlated to age and body mass. Muscle size and the amount of fat in the muscles was studied from MRI cross sections. When the back muscles were degenerated, they were small and contained fat deposits. By contrast, the psoas muscles never showed gross fat deposits. Degeneration of both the lumbar discs and muscles increased with age. No correlation was found between muscle degeneration and overweight. Muscle degeneration is as common as disc degeneration in the lumbar area. MRI is an excellent method to assess both muscle and disc degeneration.

A 31-year-old overweight man, suffering from high-blood pressure, was hospitalized for transient fits and hemiparesis. MRI disclosed a large irregular mass affecting the vault, meninges and invading the parietal lobe. At neurosurgery, the lesion was necrotic, hemorrhagic and poorly demarcated from the surrounding brain. Histopathology revealed a benign Langerhans cell histiocytosis. No other systemic nor organic lesions could be discovered. After additional local radiotherapy, the patient recovered completely and regained normal activities 6 months later.

A 54-year-old black male with a 15-year history progressive lower extremity weakness was evaluated with a thoracic MRI that revealed epidural lipomatosis extending from T1-T10 with an associated syrinx at T1-3. He was neither overweight nor taking steroids. A multilevel thoracic laminectomy with resection of lipoma was performed without directly addressing the syrinx. Postoperatively, his symptoms improved and an MRI obtained 1 year after surgery demonstrated resolution of the syrinx. This is the only case of epidural lipomatosis with an associated syrinx that we have seen reported in the world literature.

Osteoarthritis of the hip joint is a very common disease. There is a minor prevalence of males. By etiology one can distinguish primary (idiopathic) from secondary osteoarthritis. Secondary are due to well-known etiologies as overweight, repetitive traumata, malposture, muscle- and tendon-imbalance etc. Osteoarthritis includes not only cartilage abnormalities, but also such of the subchondral-region, synovialis, synovial fluid and periarticular muscles. The cartilage shows in osteoarthritis typically edema and swelling, defects with tears, fibrillation, and "baldness" and (or) cartilagenous repair-islands and joint space narrowing as well, while subchondrally micro-edema, necrosis, ev. microfractures, "cysts", demineralisation followed by sclerosis, osteophyte-formation and deformity is seen. With conventional radiographs and CT joint space narrowing, subchondral cysts, sclerosis and osteophytes and deformities are well delineated, MRI however allows visualization of subtle bone marrow and cartilage abnormalities. Clinically, the diagnosis of pre-osteoarthritis becomes more and more important. This includes e.g. deformities and malpostures, labrum-pathologies and structural imbalances. There are three prognostic different types of hip-osteoarthritis depending on the migration of the head of the hip joint: the most common are the latero-cranial and the medio-caudal ones, while the central one is found very rarely. Basic imaging method are conventional radiographs, and CT, followed by MRI. The diagnosis of an "activated osteoarthritis" is made by bone-scintigraphy or MRI with i.v. application of contrast-media. The labrum- and cartilage diagnosis should be done with MRI or MR-arthrography. Functional computer-animated analysis will be of great diagnostic value in the near future. MRI indications are differences between clinical results and imaging, missing clinical improvement of an "activated" osteoarthritis under standard therapy, unclear joint-pain and before any arthroscopy.

Obesity has been shown to increase lumbar CSF pressure in healthy subjects. The authors studied lumbar CSF opening pressure in 18 obese, 33 overweight, and 49 nonoverweight subjects with normal MRI and MR venography (MRV) of the brain. No subject had a CSF pressure above 200 mm H2O. Obesity does not cause abnormal CSF pressure in subjects with normal MRV. Individuals with a CSF pressure higher than 200 mm H2O should undergo MRV to exclude cerebral venous thrombosis.

The association between lipoprotein (a) [Lp(a)] and cardiovascular diseases is well known. Lp(a) is an independent risk factor for the development of atherosclerosis. Little information concerning Lp(a) during childhood is available. The aim of the present investigation was to determine the Lp(a) concentration in a cohort of children aged between 4 and 15 yr and to correlate Lp(a) with: a) overweight status; b) body fat distribution; c) family history of vascular diseases in their parents and grandparents. Six hundred and eighty-nine children (350 males, 339 females), were enrolled in the study. BMI as index of being overweight was calculated; the waist-to-hip ratio (WHR) and the waist-to-thigh ratio (WTR) were calculated to obtain two anthropometric indexes for the pattern of body fat distribution. The areas of visceral (VAT) and subcutaneous adipose tissue (SAT) were evaluated by MRI at the L4-L5 level in only 30 overweight subjects. The serum of Lp(a), total cholesterol (TC), HDL-cholesterol, LDL-cholesterol and triglycerides were evaluated in the whole population. Moreover, the same biochemical study was performed in 70 children's parents randomly chosen. A structured questionnaire was administered to the children's parents to investigate the presence of cardiovascular disease (CVD) in family stories. Our data show no Lp(a) serum differences between children according to sex, age and body composition. The strong correlation between the children's and the parents' Lp(a) concentrations and the occurrence of CVD in their grandparents suggests that Lp(a) represents an important independent early risk factor for the development of CVD in adulthood. Measurements of Lp(a) in childhood may help to evaluate this risk in subjects with family history of cardiovascular diseases.

In this paper we investigated the effect of fluoxetine (60 mg/d) on serum lipids, glucose and insulin concentrations and blood pressure by means of a randomized, double-blind placebo controlled trial. Thirty-eight overweight (BMI: 26-30 kg/m2), nondiabetic, nonhypertensive men with an abdominal fat distribution (waist/hip ratio: > 0.97) received dietary advice and placebo or fluoxetine for 12 weeks. The changes in serum parameters and blood pressure in the fluoxetine treated group were not different from the placebo treated group, despite a significantly larger weight loss in the fluoxetine group. In both groups serum total-cholesterol concentrations, serum LDL-cholesterol concentrations and the HDL/LDL ratio were significantly improved after treatment. Reductions in fasting glucose concentration and systolic blood pressure were only significant in the placebo group. A reduction of serum triglycerides and an increase of HDL-cholesterol were found in the fluoxetine treated group. In the total study population the changes in serum lipids seemed to be more strongly related to the change in total body fat or subcutaneous abdominal fat (assessed by MRI) compared to the change in visceral fat. The improvement of most of the serum lipids was related to the change in total body fat independent of the mechanism for attaining this fat loss. Our results indicate that fluoxetine treatment has no specific effect beyond that expected for weight loss on serum lipid, glucose and insulin concentrations, and blood pressure in overweight men.

Clinical studies in adults indicate there is a positive and significant association between insulin resistance, dyslipidaemia, fasting intestinally derived lipoproteins [via apoB48 (apolipoprotein B48)] and visceral fat. All of these factors contribute to increased risk of CVD (cardiovascular disease). Since little is known about postprandial dyslipidaemia in overweight children, we sought to compare fasting levels of apoB48 with the HOMA-IR (homoeostasis model assessment of insulin resistance) score, classic lipid profile and VAT (visceral adipose tissue). Pre-pubertal, overweight boys and girls were recruited from the wider-Edmonton area (Alberta). Body composition was determined using both dual-energy X-ray absorptiometry and MRI (magnetic resonance imaging). Fasting apoB48 was quantified in plasma using an adapted SDS/PAGE immunoblotting technique, and insulin, glucose, TC (total cholesterol), TAG (triacylglycerol), LDL (low-density lipoprotein) and HDL (high-density lipoprotein) were determined by calorimetric assay. In this overweight sample, we observed elevated fasting apoB48 concentrations, greater than the normal adult range. In addition, apoB48 was significantly related to HOMA-IR and TAG levels. Although apoB48 was positively correlated with TC and LDL and negatively associated with HDL, these relationships did not achieve significance. Our ongoing MRI analysis reveals a positive relationship between apoB48 and VAT volume. To our knowledge, this is the first study to report apoB48 concentrations in overweight pre-pubertal children. Thus this article will provide a brief rationale for our study and its methodology.

The purpose of this study was to examine interrelationships between IGF-I, IGF binding proteins (IGFBPs) and adiposity in 178 overweight Hispanic adolescents (11.2 +/- 1.7 yr; body mass index: 28.2 +/- 5.4 kg/m2). Immunoradiometric assays were used to measure IGF-I, IGFBP-1 and IGFBP-3. Total fat and lean tissue mass were measured by DEXA and visceral and subcutaneous adipose tissue by MRI. IGF-I and IGFBP-3 remained inversely correlated with total body fat mass (r = -0.52, p < 0.001 and r = -0.25, p < 0.01, respectively) after controlling for covariates. IGFBP-1 was inversely correlated to total fat mass (r = -0.55, p < 0.001) in simple correlations; however, this relationship was eliminated after controlling for covariates (r = 0.02, p = 0.85). Correlations with visceral and subcutaneous adipose tissue yielded similar results. These results demonstrate that IGF-I, IGFBP-1 and IGFBP-3 are all inversely related to adiposity in Hispanic children.

Obesity is a global epidemic, responsible for 2000 premature deaths in Ireland each year. The extent of this epidemic was quantified by the National Taskforce on Obesity (IOTF), whose report, published in 2005, found that 39% of adults in Ireland were overweight and 18% obese with obesity in adults predicted to increase by 1% per year. In light of the clear evidence that we, as a nation, are quite literally expanding, how well equipped are Irish hospitals and, in particular, radiology departments, to deal with patients of increasing size and weight? The purpose of this study was to quantify the weight limits and girth restrictions of the radiology equipment, in particular CT, MRI and fluoroscopy, in hospitals, both public and private, in Ireland in an attempt to answer this question.
