Chron’s Disease is a chronic inflammatory intestinal disease, first described at the beginning of the last century. The disease is characterized by the alternation of periods of flares and remissions influenced by a complex pathogenesis in which inflammation plays a key role. Crohn’s disease evolution is mediated by a complex alteration of the inflammatory response which is characterized by alterations of the innate immunity of the intestinal mucosa barrier together with a remodeling of the extracellular matrix through the expression of metalloproteins and increased adhesion molecules expression, such as MAcCAM-1. This reshaped microenvironment enhances leucocytes migration in the sites of inflammation, promoting a TH1 response, through the production of cytokines such as IL-12 and TNF-α. IL-12 itself and IL-23 have been targeted for the medical treatment of CD. Giving the limited success of medical therapies, the treatment of the disease is invariably surgical. This review will highlight the role of inflammation in CD and describe the surgical approaches for the prevention of the almost inevitable recurrence.
While overall hospitalizations for SLE patients declined, those for cerebrovascular accident, acute coronary syndrome and chronic renal failure as underlying primary diagnosis increased during the study period.
Background: Partial surveys in sub-regions of Sardinia have suggested a high prevalence of multiple sclerosis (MS) on the island, relative to other Mediterranean populations. We assessed the island-wide prevalence of MS and its detailed distribution in Sardinia. Methods: The study population consisted of 5677 MS patients, 1735 men and 3942 women, living in Sardinia. Neurologists retrospectively examined electronic and paper-based records of patients with a diagnosis of MS. The data were then linked to the administrative health information systems. Crude, age-, and sex-specific prevalence estimates of disease were calculated. Results: The overall age-adjusted MS prevalence was 330 per 100,000 (95% confidence interval (CI) 321–338) in individuals older than 15 years, 447 in women (95% CI 433–461), and 205 in men (95% CI 195–214). The prevalence was highest in the Ogliastra and Nuoro districts, respectively, 425 (95% CI 372–478) and 419 (95% CI 387–451), and lowest in the Olbia-Tempio district, 217 (95% CI 195–239). Most cases had relapsing–remitting MS (79.3%), 16.3% had secondary-progressive MS, and 4.4% had primary-progressive MS. Conclusion: These prevalence are among the highest reported so far worldwide. They provide estimates for comparative analyses in other populations and are essential for public health interventions.
The aim of this study was to evaluate systemic sclerosis (SSc) hospitalizations through a retrospective population-based study analyzing administrative data during 2001-2012 in Sardinia, an Italian region with universal Health System coverage. Data on hospital discharge records with ICD-9-CM code for SSc (710.1) were obtained from the Department of Health and Hygiene. Two-tailed Cochran-Armitage test for trend was applied to analyze the annual trend for primary and non-primary discharge diagnoses. SSc prevalence was also estimated. This study included 4981 hospitalizations in 736 patients (84.8 % women). Hospitalizations with SSc as primary diagnosis were 3631 (72.9 %). Their annual number significantly increased during study period, from 143 in 2001 to 390 in 2012. Annual trend analysis revealed statistically significant increase in number and percentage of interstitial lung disease (p < 0.0001), pulmonary arterial hypertension (p < 0.0024), osteoporotic fragility fractures (p < 0.0001), ulcers, and gangrene (p = 0.0037) as non-primary diagnoses associated with SSc. Although the number of admissions with SSc as non-primary diagnosis showed a slight reduction during the study period, the annual number and percentage of admissions with respiratory failure (p = 0.0016) and congestive heart failure (p < 0.0001) as primary diagnosis showed a significant upward trend. Admissions for intravenous infusion, mainly day-hospital, accounted for 19.1 % of all hospitalizations for SSc and showed a significant (p = 0.0002) upward trend in 2001-2012. The 2012 SSc prevalence in Sardinia was estimated to be 34.8 per 100,000 inhabitants. Hospital care utilization for SSc is changing over time, showing increased hospitalizations aimed at the early recognition and treatment for the major manifestations and complications of SSc.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
