Little is known regarding the environmental factors at play in igniting rheumatoid arthritis (RA) autoimmunity, although an association between Mycobacteria and RA has been documented. This pilot study focused on examining a possible involvement of Mycobacterium tuberculosis (MTB) and Mycobacterium avium ss. paratuberculosis (MAP) in RA. We measured out the serum levels of IgG antibody against different mycobacterial antigens in Sardinian patients and controls, by an enzyme-linked immunosorbent assay. The population study was composed of 61 RA patients under different therapies and 52 healthy controls, whereas the antigens tested were MTB lipoarabinomannan (ManLAM), MAP heath shock protein 70, and MAP protein tyrosine phosphatase. The frequencies of anti-ManLAM antibodies were higher in the RA group (23 %) compared to the healthy controls (5.7 %) (AUC = 0.7; p < 0.0001), whereas serum reactivity to MAP antigens was not observed. ManLAM antigen was also detected in the plasma of three RA patients (which were anti-ManLAM antibody positive) by Western blot analysis using anti-Man-LAM monoclonal antibodies. The data produced corroborate the hypothesis of a potential association between MTB ManLAM and RA disease, but so far, further studies are necessary to understand its role in RA pathogenesis.

Heat shock protein (HSP) family members are highly conserved in both prokaryotic and eukaryotic organisms and are known to be immunodominant antigens in many bacteria. In particular, HSP70 has been linked to multiple sclerosis (MS), even if the available data are contradictory. Since different studies conducted on Sardinian subjects, have linked Mycobacterium avium subspecies paratuberculosis (MAP) presence to MS disease, and in view of the fact that human HSP70 is highly homologue to the majority of mycobacterial HSP70 proteins, we searched for anti-MAP HSP70 antibodies in the sera of 268 MS patients and 231 age and sex-matched healthy controls (HCs). All the subjects enrolled in the study were from Sardinia, which is an excellent setting for investigation since it has one of the highest prevalence of MS worldwide. HSP70 detection was carried out using ELISA methodology. A statistically significant difference was found between MS patients and HCs when analyzing the humoral response mounted against MAP HSP70 protein. Our study confirms that mycobacterial HSP70 might be involved in MS, and provides another piece of evidence sustaining the role played by MAP in MS in the context of Sardinian population.

In November 2011 a 75-year-old man was admitted to our emergency department with a low back pain caused by a traumatic L1 vertebral collapse with backward projection of posterior wall superior third. The indication for neurosurgical instrumentation was placed, although he refused the treatment. Hence he was treated conservatively without a significant improvement up to January 2012 when, still refusing surgery, he accepted to undergo percutaneous vertebroplasty with a novel bioactive injectable strontium-hydroxyapatite cement. Vertebroplasty was performed without complications. A CT scan, performed the day after the procedure, ruled out extravertebral cement leakage. Pain improvement was significant (preprocedure VAS 10, one-week VAS 4) with a gradual decrease up to three months when it stabilized at 2. CT examination after 1 year showed a good cement osseointegration with osteophytic spurs bridging the superior endplate of the level involved to the inferior one of the level above. The new bone ingrowing property of the strontium-hydroxyapatite containing cement permits to extend the treatment indication also to unstable collapses in which the risk of pseudoarthrosis is very high. In this reported case we evaluated the potential role of percutaneous vertebroplasty in traumatic burst fracture with spinal channel involvement.
RESUMO
INTRODUCTION: This study aims to assess the effectiveness of combined procedure of cryoablation and vertebroplasty (CVT) for reduction of pain and improvement of the quality of life in patients with single painful metastatic vertebral fractures. METHODS: We retrospectively analyzed data from 23 patients with single vertebral metastasis treated with combined procedure of CVT, compared with those obtained in 23 patients treated by vertebroplasty. Pain intensity was evaluated by a visual analog scale (VAS) score administered before and 1 day, 1 week, and 1, 3, and 6 months after procedure. Quality of life was evaluated by an Oswestry Disability Index (ODI) score administered before and at 3 and 6 months after procedure. RESULTS: Procedural success was achieved in all patients without any complications. The VAS and ODI scores showed a reduction in both groups during follow-up (VAS score, p < 0.05 and p < 0.001, respectively; ODI score, p < 0.0001). No difference of the VAS and ODI scores were observed before treatment (p = 0.33 and 0.78, respectively). VAS score showed a difference at 1 week and 1, 3, and 6 months after treatment (p < 0.001). ODI score showed a difference at 3 and 6 months after treatment (p < 0.001). CONCLUSION: Our findings suggested that combined procedure of CVT is safe and effective for pain relief in single metastatic vertebral fractures, especially when other standard palliative treatments have failed, and improves disability. Careful needle positioning and accurate fluoroscopic and CT guidance are mandatory for a complication-free treatment.

BACKGROUND AND AIMS: A demographic analysis in the Mediterranean island of Sardinia revealed marked differences in extreme longevity across the 377 municipalities and particularly identified a mountain inner area where the proportion of oldest subjects among male population has one of the highest validated value worldwide. The cause(s) of this unequal distribution of male longevity may be attributed to a concurrence of environmental, lifestyle and genetic factors. METHODS AND RESULTS: In this study we focussed on some lifestyle and nutrition variables recorded in the island's population in early decades of 20th century, when agricultural and pastoral economy was still prevalent, and try to verify through ecological spatial models if they may account for the variability in male longevity. By computing the Extreme Longevity Index (the proportion of newborns in a given municipality who reach age 100) the island's territory was divided in two areas with relatively higher and lower level of population longevity. Most nutritional variables do not show any significant difference between these two areas whereas a significant difference was found with respect to pastoralism (P = 0.0001), physical activity estimated by the average slope of the territory in each municipality (P = 0.0001), and average daily distance required by the active population to reach the usual workplace (P = 0.0001). CONCLUSION: Overall, these findings suggest that factors affecting the average energy expenditure of male population such as occupational activity and geographic characteristics of the area where the population mainly resides, are important in explaining the spatial variation of Sardinian extreme longevity.

INTRODUCTION: The aim of this study was to examine the role of palliative percutaneous secondary lesions bone treatment by comparing the visual analogue scale (VAS) scores of cryoablation plus vertebroplasty versus radiofrequency (RF) plus vertebroplasty so as to determine their feasibility, reliability and efficacy in a short-term series. METHODS: Combined RF thermal ablation plus osteoplasty or cryoablation plus osteoplasty was performed in osteolytic secondary bone localisations in 30 consecutive patients who were suffering from pain refractory to conservative therapies. We evaluated pain with the VAS during the preoperative period and at four hours, 24 hours, one week, one month, three months and six months post procedure. RESULTS: There were no statistically significant differences in the VAS score between patients treated with cryoablation plus osteoplasty and those treated with RF ablation plus osteoplasty at one week (p-value is 0.34), one month (p-value is 1), three months (p-value is 0.68) and six months (p-value is 0.65) post procedure. Patients treated with cryoablation plus vertebroplasty have less pain at four hours (p-value less than 0.001) and 24 hours (p-value less than 0.001) than patients treated with RF ablation plus vertebroplasty. CONCLUSION: Both RF ablation and cryoablation are optimal techniques in the treatment of painful bone metastatic cancer. Cryoablation achieves less treatment-related pain during the early period of follow-up and better volume control by real-time depiction of ablation margins.

BACKGROUND: Percutaneous vertebroplasty is currently an alternative for treating vertebral fractures of the thoracic and lumbar spine, providing both pain control and vertebral stabilization. In the cervical spine, however, percutaneous vertebroplasty is technically challenging because of the complex anatomy of this region. QUESTIONS/PURPOSES: We evaluated the technical feasibility, complication rate, and ability of percutaneous vertebroplasty to provide pain relief in patients with painful metastatic cervical fractures. METHODS: We retrospectively reviewed 62 patients (24 men) who, between May 2005 and May 2009, underwent vertebroplasty to treat painful metastatic cervical fractures. Each patient was evaluated by a visual analog scale for pain, number of pain analgesics, and CT and MRI before, the day after, and at 3 months after the procedure. RESULTS: Two of the 62 patients had asymptomatic cement leakage in the soft tissues. We observed no delayed complications. Mean pretreatment and 24-hour posttreatment visual analog scale pain scores were 7.9±1.7 and 1.5±2, respectively. Immediately after surgery, the pain completely disappeared in 25 (40%) patients. Administration of analgesics was suspended in 34 (55%) patients whereas in 27 (39%) patients the median analgesics use decreased from two pills per day (range, 0-3) to 0 (range, 0-3). In two (3%) patients, analgesics administration was continued due to the persistence of pain. At 3 months, the patients reported a mean visual analog scale pain score of 1.7±2. CONCLUSIONS: Our data suggest, in selected patients, percutaneous vertebroplasty may be performed with a high technical success rate combined with a low complication rate, providing immediate pain relief lasting at least 3 months and a reduction in the use of analgesic drugs. LEVEL OF EVIDENCE: Level IV, therapeutic study. See Guidelines for Authors for a complete description of levels of evidence.

Percutaneous vertebral augmentation techniques performed with vertebroplasty or kyphoplasty are safe and effective for the treatment of osteoporotic vertebral compression fractures, primary or secondary spine tumors, and selected traumatic fractures. This article compares the procedures and outlines their advantages and disadvantages. It concludes that vertebroplasty should be performed in most cases, but kyphoplasty is preferable in selected cases.

Here we present the development of a specific DNA detection method using fluorescent semiconductor quantum dots (QDs) and magnetic beads (MBs) for fast detection of Mycobacterium spp., dispensing with the need for DNA amplification. Two biotinylated oligonucleotide probes were used to recognize and detect specific complementary mycobacterial target DNA through a sandwich hybridization reaction. Cadmium selenite QDs conjugated with streptavidin and species-specific probes were used to produce a fluorescent signal. MBs conjugated with streptavidin and a genus-specific probe were used to isolate and concentrate the DNA targets. The application of the proposed method to isolated bacteria produced the expected result in all cases. The minimum detection limit of the assay was defined as 12.5 ng of DNA diluted in a sample volume of 20 microl. In order to obtain an indication of the method's performance with clinical samples, we applied the optimized assay to the detection of Mycobacterium tuberculosis in DNA isolated from bronchoalveolar lavage specimens from patients with tuberculosis and Mycobacterium avium subsp. paratuberculosis in DNA isolated from feces and paraffin-embedded tissues in comparison with culture, Ziehl-Neelsen staining, and real-time PCR. The concordance of these methods compared to the proposed method with regard to positive and negative samples varied between 53.84% and 87.23% and between 84.61% and 100%, respectively. The overall accuracy of the QD assay compared to real-time PCR was 70 to 90% depending on the type of clinical material. The proposed diagnostic assay offers a simple, rapid, specific, and cost-effective method for direct detection and identification of mycobacterial DNA in clinical samples.

This study was designed to confirm relationships between decrease of bone mineral density and increase of marrow fat and to delineate, through MR spectroscopy, vertebral body at high risk for compression fracture onset to justify prophylactic vertebroplasty. We enrolled 127 women: 48 osteoporotic, 36 osteopenic, and 43 normal subjects, who underwent DXA and MR examination of spine. Then, we selected 48 patients with at least two acute osteoporotic vertebral fractures with interposed normal "sandwich" vertebrae; all patients underwent MR examination of spine. Significant statistical differences were found among "Fat Fraction" (FF) values in normal, osteopenic, and osteoporotic subjects: 59.8 ± 5.1%; 64.8 ± 4.4%; and 67.1 ± 3.3%. A mild, significant, negative correlation was observed between T-score and vertebral fat content (r = - 0.585; P = 0.0000). In the second part of the study, 9 new vertebral fractures were observed in 48 patients (19%): 6 were "sandwich" vertebrae (12.5%), and 3 were located in distant vertebral body. The mean FF in sandwich fractured vertebrae was 72.75 ± 1.95 compared with the FF of the nonfractured sandwich, and distant control vertebrae were 61.83 ± 3.42 and 61.42 ± 3.64. We found a significant statistical difference between fractured and nonfractured vertebrae (P < 0.001). The results of this study suggest that MR spectroscopy could be a reliable index to predict the risk of new compression vertebral fracture and could be used for vertebroplasty planning contributing to clarify the possibility to add prophylactic PVP to standard treatment.

A case report of a non-diabetic alcoholic patient (ethanol intake >220 g/d) who experienced severe hypertriglyceridemia (12.679 mg/dL) without pancreatitis or detectable genetic factors responsible for severe dyslipidemia is described. Following the normalization of triglyceride and cholesterol levels, through lipid-free parenteral nutrition therapy, a regimen of alcohol withdrawal and a well-balanced diet with less than 10% saturated fat maintained a normal lipid profile without requiring any lipid-lowering drug. The absence of organ damage in the patient is likely to be attributed to the short duration of the elevated triglyceride peak. The treatment of this disorder does not necessarily require LDL-apheresis but can be simply managed by parenteral therapy provided that no other risk factors are present.

The first percutaneous vertebroplasty, used to treat a painful cervical haemangioma, was performed by a French team in 1984 and reported in the literature in 1987. This technique has rapidly become the standard of care for treatment of medically refractory painful vertebral compression fractures. Vertebral fractures usually become evident because of pain of varying intensity that reduces the patient's quality of life, producing functional limitations, depression, disability, height loss, spinal instability and kyphotic deformity associated with impaired lung capacity. Many diseases may underlie vertebral compression fractures, such as osteoporosis, trauma, neoplasms and haemangioma. Vertebroplasty, as derived from our experience and a review of the literature data, has more than 70%-90% effectiveness for short-term pain reduction and return to activity. The aim of this paper was to describe the state of the art of this spinal interventional radiology procedure and to examine the future directions of percutaneous vertebroplasty.

Body composition (BC) assessment is indispensable to evaluate nutritional status and thus health, both at the population and individual level, and to assess the efficacy of primary and secondary preventive nutritional strategies. Changes in BC, including the regional distribution of body fat, largely occur during pubertal transition, with marked differences between genders. They may, however, also occur in the elderly, who experience significant changes in the ratio between body fat and muscle with aging. The development and implementation of more sophisticated techniques (e.g. BC assessment at the molecular and atomic levels) could provide a major contribution to determining BC at different levels. This review discusses the application of dual-energy X-ray absorptiometry (DXA) on BC determination, given that DXA has the potential to provide overall and regional assessment of BC in terms of fat, lean mass and bone. DXA is widely used in many clinical settings primarily diagnosis osteoporosis. This article describes the use of whole-body DXA in assessing BC in patients with chronic diseases (e.g. metabolic syndrome) as well as in different sport activities to evaluate the effects of exercise.

PURPOSE: This study was undertaken to evaluate the diagnostic capabilities of 3-Tesla (T) magnetic resonance (MR) in vertebral osteoporosis. MATERIALS AND METHODS: Thirty subjects (ten healthy controls, ten with osteoporosis but no fracture, ten with osteoporotic vertebral fractures) underwent MR of the lumbar spine. Turbo spin echo (TSE) T1-, T2- and T2- spectral selection attenuated inversion recovery (SPAIR) weighted imaging and spectroscopy for the selective evaluation of water and fat content were performed. The apparent diffusion coefficient (ADC) was calculated, and diffusion tensor imaging (DTI) was performed to create a map of the spatial arrangement of the tissue structures. RESULTS: Morphological imaging detected recent vertebral fractures. In osteoporotic patients, spectroscopic imaging demonstrated an increase in the saturated fats and a decrease in the ADC, whereas the data provided by DTI demonstrated a bone structure with medium-degree anisotropy. DISCUSSION: Osteoporosis is characterised by trabecular thinning, with an increase in the intertrabecular spaces, which are filled with fats. The anisotropic study and the subsequent assessment of colour and vector maps can provide a noninvasive tool for assessing the risk of fracture due to osteoporosis.

UNLABELLED: Hypothalamic amenorrhea in anorexia nervosa often precedes weight loss and may persist after re-feeding and restoration of a stable normal weight. AIM: To assess the rate of persistent amenorrhea in anorexia nervosa (AN) after re-feeding and the relations of this condition with body composition changes and other endocrine parameters. METHODS: A cohort of 250 female outpatients was studied to assess persistent amenorrhea prevalence after stable weight recovery. Among these, we selected 20 AN female patients (age 16.5-35), 10 with amenorrhea (group 1) and 10 with normal menses (group 2). We collected data such as age, age at menarche, age at onset of AN, actual body mass index (BMI) and at onset of AN, duration of disease. Physical activity has been evaluated as minute per day. The following data were obtained: prolactin, growth hormone, estradiol, luteinizing hormone, follicle stimulating hormone, thyroid stimulating hormone, free triiodothyronine, free thyroxine, free urinary cortisol, serum calcium and phosphates, urinary calcium, phosphaturia and alkaline phosphatase. Body composition was assessed with a dual energy x-ray absorptiometry (DEXA). RESULTS: Thirty-five patients (14%) over a cohort of 250 where still amenorrhoic after stable weight recovery. No significance was found in the evaluation of blood biochemical tests of the 2 groups. Free urinary cortisol was significantly higher in amenorrhoic patients (58.14+/-0.4 vs 15.91+/-9.5), p=0.02. The analysis of body composition has shown a percentage of fat of 22.23+/-5.32% in group 1 and of 26.03%+/-9.1% in group 2, respectively, showing no significant differences. Amenorrhoic patients carried on doing a significantly heavier physical activity than eumenorrhoic patients. CONCLUSIONS: An adequate body composition and a well represented fat mass are certainly a necessary but not sufficient condition for the return of the menstrual cycle. Such menstrual cycle recovery would probably need other conditions at present being studied and evaluated to occur, such as secretory patterns of leptin and its correlations with adrenal function.

The purpose of this retrospective study was to assess the effectiveness and safety of Percutaneous Vertebroplasty and Kyphoplasty, in the treatment of pain deriving from neoplastic vertebral compression fractures (VCF). We treated 33 oncologic patients with these new techniques (2 pts with aggressive haemangiomas, 8 pts with myelomas and 23 pts with metastases) suffering from severe motion pain in the back, notwithstanding conservative treatment with medication and corset therapy, in the absence of neurological signs. In 3 selected patients we associated radiofrequency heat ablation with vertebroplasty in the treatment of metastases. The aim is to destroy tumor tissue and to thrombose the paravertebral and intravertebral venous plexus before stabilizing the vertebra.
