Background: The nematode Strongyloides stercoralis has a very particular autoinfection life-cycle which leads to chronic infections remaining undetected for decades. However, hyperinfection can occur in patients receiving immunotherapy resulting in high mortality rates. The main objective of this study was to assess the results of a 10-year multicenter surveillance program performed in an area with dense immigration in Barcelona, Spain. Methods: From January 2003 to December 2012, all individuals with Strongyloides stercoralis infection attending the four centers with diagnostic capability in the North Metropolitan area of Barcelona were recorded. Results: The annual detection rate was 0.2 new diagnosed cases x10 000 inhabitants/year and 1 case x10 000 immigrants/year. Many patients were immigrants (63; 90.0%), asymptomatic (45; 64.3%) and with a high eosinophil count (63; 90.0%). Immunosuppression was present in 11 (15.7%) patients, among whom two (2.8%) cases of disseminated hyperinfection were recorded. Ivermectin was prescribed in 45 (76.3%) and albendazole in 14 (23.7%). Following treatment seven patients (11.9%) receiving albendazole presented relapse, that is, albendazole failed to clear the parasite in 50% of these drug-treated patients (p < 0.001). Conclusions: During the study period, 90% of the cases of Strongyloides stercoralis diagnosed could be considered as imported by immigrants, most being asymptomatic and with eosinophilia. The infection is probably largely underestimated and population-based studies are needed to determine its true prevalence. Meanwhile, diagnosis must be based on active investigation of the helminth (serology and feces culture), especially in immunocompromised patients. The implementation of pre-immunosuppression protocols with the aim of identifying Strongyloides stercoralis is encouraged with empirical treatment with ivermectin being recommended in sites without diagnostic facilities. © Royal Society of Tropical Medicine and Hygiene 2013.

An 84-year-old man who was receiving oral anticoagulation therapy presented with complete lumbar plexus palsy caused by a massive psoas haematoma. Conservative treatment rather than drainage of the haematoma was undertaken, because of the risk of bleeding complications and mortality. At the one-year follow-up, the patient had no clinical signs of neurological recovery. The patient died 2 months later due to his concurrent medical problems. A high degree of suspicion is needed for the diagnosis because of the insidiously developing neurological deficit.

Background: Community-acquired pneumonia (CAP) has large impact on direct healthcare costs, especially those derived from hospitalization. This study determines impact, clinical characteristics, outcome and economic consequences of CAP in the adult (≥18 years) population attended in 6 primary-care centers and 2 hospitals in Badalona (Spain) over a two-year period.Methods: Medical records were identified by codes from the International Classification of Diseases in databases (January 1st 2008-December 31st 2009).Results: A total of 581 patients with CAP (55.6% males, mean age 57.5 years) were identified. Prevalence: 0.64% (95% CI: 0.5%-0.7%); annual incidence: 3.0 cases/1,000 inhabitants (95% CI: 0.2-0.5). Up to 241 (41.5%) required hospitalization. Hospital admission was associated (p<0.002) with liver disease (OR=5.9), stroke (OR=3.6), dementia (OR=3.5), COPD (OR=2.9), diabetes mellitus (OR=1.9) and age (OR=1.1 per year). Length of stay (4.4±0.3 days) was associated with PSI score (β=0.195), in turn associated with age (r=0.827) and Charlson index (r=0.497). Microbiological tests were performed in all inpatients but only in 35% outpatients. Among patients with microbiological tests, results were positive in 51.7%, and among them, S pneumoniae was identified in 57.5% cases. Time to recovery was 29.9±17.2 days. Up to 7.5% inpatients presented complications, 0.8% required ICU admission and 19.1% readmission. Inhospital mortality rate was 2.5%. Adjusted mean total cost was €2,332.4/inpatient and €698.6/outpatient (p<0.001). Patients with pneumococcal CAP (n=107) showed higher comorbidity and hospitalization (76.6%), higher PSI score, larger time to recovery and higher overall costs among inpatients.Conclusions: Strategies preventing CAP, thus reducing hospital admissions could likely produce substantial costs savings in addition to the reduction of CAP burden. © 2012 Sicras-Mainar et al.; licensee BioMed Central Ltd.

Background: The p53 transcription factor is located at the core of a complex wiring of signaling pathways that are critical for the preservation of cellular homeostasis. Only recently it has become clear that p53 regulates the expression of several long intergenic noncoding RNAs (lincRNAs). However, relatively little is known about the role that lincRNAs play in this pathway. Results: Here we characterize a lincRNA named Pint (p53 induced noncoding transcript). We show that Pint is a ubiquitously expressed lincRNA that is finely regulated by p53. In mouse cells, Pint promotes cell proliferation and survival by regulating the expression of genes of the TGF-β, MAPK and p53 pathways. Pint is a nuclear lincRNA that directly interacts with the Polycomb repressive complex 2 (PRC2), and is required for PRC2 targeting of specific genes for H3K27 tri-methylation and repression. Furthermore, Pint functional activity is highly dependent on PRC2 expression. We have also identified Pint human ortholog (PINT), which presents suggestive analogies with the murine lincRNA. PINT is similarly regulated by p53, and its expression significantly correlates with the same cellular pathways as the mouse ortholog, including the p53 pathway. Interestingly, PINT is downregulated in colon primary tumors, while its overexpression inhibits the proliferation of tumor cells, suggesting a possible role as tumor suppressor.Conclusions: Our results reveal a p53 autoregulatory negative mechanism where a lincRNA connects p53 activation with epigenetic silencing by PRC2. Additionally, we show analogies and differences between the murine and human orthologs, identifying a novel tumor suppressor candidate lincRNA. © 2013 Marín-Béjar et al.; licensee BioMed Central Ltd.

Objetives: This paper aims to compare the costs of initiating pregabalin or gabapentin in the therapeutic management of patients with painful axial radiculopathy in routine medical practice. Methods: A retrospective claim database analysis was carried-out using medical records of patients of both gender aged >18 years with axial painful radiculopathy (ICD-9-CM codes: 353.0 [cervical], 353.3 [thoracic] or 353.1 [lumbar]) who initiated pregabalin or gabapentin therapy between 2006 and 2008. The economic evaluation included healthcare resource utilisation and corresponding costs from a third-payer perspective during 12 months post index date. Estimates of indirect costs due to sick leave were also computed. Results: A total of 571 records were eligible for analysis: 375 (66%) treated with pregabalin and 193 (34%) gabapentin. Time since diagnosis, duration of treatment, prevalence of most co-morbidities and previous use of analgesics were comparable. However, concomitant use of analgesics was higher in the gabapentin cohort; 3.1 (1.7) vs. 2.8 (1.8); p<0.05, mainly due to greater use of opioids (31.1% vs. 21.2%; p<0.05) and non-narcotic drugs (63.7% vs. 52.1%; p<0.01). Adjusted total costs per patient were significantly lower in the pregabalin group; €2.472 (2.101-2.836) vs. €3.346 (2.866-3.825); p=0.005, due to lower absenteeism costs; €1.012 (658-1.365) vs. €1.595 (1.129-2.062); p=0.042, and lower adjusted healthcare costs; €1.460 (1.360-1.560) vs. €1.750 (1.618-1.882); p=0.001. Conclusion In a population setting, pregabalin-treated patients with painful radiculopathies were considerably less costly for the healthcare payer than those treated with gabapentin in routine clinical practice. Patients treated with pregabalin had significantly fewer days of sick leave than gabapentin-treated patients. © CLINICAL AND EXPERIMENTAL RHEUMATOLOGY 2013.
