Treatment of drug addiction in traumatised refugees. A case report

The comorbidity of post-traumatic stress disorder (PTSD) and drug addiction is quite often overlooked in refugees. However, the simultaneous treatment of both disorders is of elemental importance for a positive outcome in addicted and traumatised refugees. Furthermore, mutual misinterpretations of habits, behaviours and reactions through negligence of the distinct sociocultural context of patient and clinician often leads to unfavourable developments. These observations are exemplified in this case report.     

Emergency Department influenza vaccination campaign allows increasing influenza vaccination coverage without disrupting time interval quality indicators

To evaluate the impact of an influenza vaccination (IV) coverage (IVC) in a vaccination campaign of an Emergency Department (EDVC) and its impact on ED time interval quality indicators. We conducted a 4 year observational study, with an intervention during the 4th year. IVC was calculated during pre-and early-epidemic periods. During the final period, a 12 weeks EDVC was implemented. Physicians and nurses were trained and sensitized in the importance of vaccination, and their role in the prevention of severe forms of influenza was reinforced. The vaccine was proposed by physicians and nurses, and delivered by them. Repeated measures ANOVA is a validated method for related not independent groups (https://statistics.laerd.com/statistical-guides/repeated-measures-anova-statistical-guide.php). Overall, IVC was 987/3191 (30.9%) with an increasing trend from 28.8 to 33.2%. In the fourth period, out of 868 patients identified with IV indication, 288 had already been vaccinated (IVC?33.2%). After excluding patients presenting criteria of exclusion, IV was proposed to 475 patients: 317 (66.7%) accepted. The vaccination rate after patient’s acceptance was 89.6% (288/317). At the end of the EDVC, influenza vaccination coverage was 572 (284?+?288)/868 (65.9%). The delay between arrival at the ED and seeing the triage nurse and physician as well as the overall ED length of stay were not modified during the study period and before and during EDVC. EDVC effectively doubled the influenza vaccination coverage, without modifying ED time interval quality indicators.     

The involvement of the renin-angiotensin system gene polymorphisms in coronary heart disease

INTRODUCTION AND OBJECTIVES: Previous studies angiotensin-converting enzyme gene insertion/deletion polymorphism ACE (I/D), angiotensinogen gene polymorphism, and angiotensin II AT1 receptor polymorphism in relation to coronary heart disease controversial results. This study was designed to analyze the association between these gene polymorphisms and the first coronary event in individuals residing on Grand Canary Island, Spain. PATIENTS AND METHOD: Case-control study. Case subjects (n = 304) were recruited at the first coronary event; age-matched controls (n = 315) were randomly selected from the Grand Canary population. Participants were examined for the usual risk factors. Blood samples were obtained for biochemical analyses and DNA extraction. Genotyping was performed by PCR and restriction analysis. RESULTS: Neither ACE (I/D) nor AT1 receptor polymorphism was associated with coronary heart disease, whereas the frequency distribution of AGT M235T genotypes among patients and control subjects (TT: 29% and 19%; MT: 48% and 50%; MM: 22% and 31%, respectively) was statistically different (p = 0.003). Multiple logistic regression analysis identified the TT genotype of the angiotensinogen gene (OR = 1.9; 95% CI 1.1-3.4), diabetes (OR = 4.4; 95% CI 2.0-9.4) and hypertension (OR = 2.1; 95% CI 1.3-3.3) as risk factors predicting the coronary event. CONCLUSIONS: Our results provide no evidence of an association between ACE (I/D) or AT1 receptor polymorphism and coronary heart disease. However, homozygosity for the T allele of the angiotensinogen gene, diabetes and hypertension independently place individuals at higher risk of experiencing a coronary event on Grand Canary Island.     

Efficacy of rituximab in an aggressive form of multicentric Castleman disease associated with immune phenomena

Multicentric Castleman disease (MCD) is an uncommon lymphoproliferative disorder for which the best therapeutic option is not yet well established. Immune-related disorders are rare complications of MCD. We report on an MCD case in a 23-year-old patient with extensive abdominal involvement and associated immune hemolytic anemia and Raynaud phenomenon. He was negative for human immunodeficiency virus (HIV) and human herpesvirus-8 (HHV-8). After 8 courses of the anti-CD20 monoclonal antibody (rituximab), the patient achieved complete remission. Interestingly, Raynaud phenomenon disappeared under treatment and no new hemolytic events occurred. Anti-CD20 antibody treatment could be an attractive therapeutic approach for MCD, mainly when immune-related disorders are associated.     

Contractile activity of human decidual stromal cells. II. Effect of interleukin-10

CONTEXT: Human decidual stromal cells (DSC) are myofibroblast-like cells that express alpha-smooth muscle (alpha-SM) actin, a protein associated with cell contractility. Several lines of experimental evidence in humans and mice show that antiinflammatory cytokines favor normal pregnancy, whereas Th1 and inflammatory cytokines play a role in abortion. We previously demonstrated that IL-2, a Th1 cytokine, increased the contractility of human DSC. OBJECTIVE: We studied the effect of the antiinflammatory cytokines IL-10 and IL-4 on the contractility of DSC from first-trimester pregnancy. SETTING AND PATIENTS: We studied 10 healthy women who underwent elective vaginal termination of first-trimester pregnancy at Clínica El Sur, Málaga, and Clínica Ginegranada, Granada. MAIN OUTCOME MEASURE(S): After isolation of DSC, cell contractility was measured with the collagen gel contraction assay. alpha-SM actin was detected with Western blotting and immunofluorescence. RESULTS: We found that IL-10, but not IL-4, increased the volume of the collagen gel matrixes in which the cytokine-treated DSC were cultured, showing that IL-10 decreased DSC contractility. By Western blotting we demonstrated that this effect was not related to an alteration in the synthesis of alpha-SM actin. Nevertheless, we observed by immunofluorescence microscopy that DSC treated with IL-10 exhibited stress fibers with a lower content of alpha-SM actin than untreated control DSC. CONCLUSIONS: IL-10 relaxes DSC by reducing the incorporation of alpha-SM actin into their stress fibers. This relaxing activity may be of relevance for the maintenance of pregnancy.     

Intraductal papillary mucinous tumor: diagnostic and therapeutic approach

Primary cystic pancreatic neoplasms are rare tumors, with an approximate prevalence of 10% of cystic pancreatic lesions. Most of these lesions correspond to mucinous cystic neoplasm, serous cystoadenoma and intraductal papillary mucinous tumor (IPMT). IPMT is characterized by diffuse dilatation of the main pancreatic duct and/or side branches with inner defects related to mucin or tumor, or mucin extrusion from a patent ampulla. IPMT has a low potential for malignancy, with a low growth rate, a low rate of metastatic spread and postsurgical recurrence. Over the last few years, major advances have been made in the diagnostic and therapeutic management of this tumor.     

Cost of care of arterial hypertension and its impact on the budget assigned to health in Mexico

OBJECTIVE: To assess the medical care costs of hypertension and their impact on the health care expenditures and on Mexico's Gross National Product (GNP). MATERIAL AND METHODS: An ecological study was conducted from June to November 1999, at Instituto Mexicano del Seguro Social (Mexican Institute of Social Security, IMSS), in Monterrey, Nuevo Leon, Mexico. A random sample of medical charts of patients with hypertension was selected, to extract data on utilization of health services and unitary costs per care episode. The cost per care episode and per hypertensive patient was calculated by adjusting the unitary cost as a function of standard and extreme utilization of IMSS health services. The resulting figure was then projected to the total population of hypertensive patients and compared to the annual health care expenditures of Mexico. RESULTS: The annual cost per patient with hypertension was $1,067 in the standard scenario and $3,913 in the extreme scenario. The annual expenditures from hypertension corresponded to 13.95% of the budget allocated to health care and to 0.71%, of Mexico's GNP. These figures changed to 51.17% and 2.61% in the extreme scenario, respectively. CONCLUSIONS: The costs of hypertension medical care account for a good portion of healthcare resources. This problem should be analyzed by multidisciplinary health teams in search of more efficient medical care alternatives.     

Impact of physician specialty on the cost of nonvariceal upper GI bleeding care

OBJECTIVE: Upper GI bleeding (UGIB) is a common medical emergency that leads to a high consumption of medical resources and costs. We aimed to analyze the influence of physician specialty on the costs of nonvariceal UGIB care. METHODS: We retrospectively assessed 350 nonvariceal UGIB episodes that were primarily cared for by gastroenterologists (n = 142), internists (n = 67), or surgeons (n = 141). Gastroenterologists followed evidence-based clinical protocols that included early endoscopy and early hospital discharge for uncomplicated bleeding. A risk score system was used to control for severity of illness. Linear regression analyses were performed to find out predictors of costs and the influence of specialist care on length of stay (LOS). RESULTS: The overall mean hospital cost was significantly lower in patients cared for by gastroenterologists (EUR 1,630) than in those managed by internists (EUR 3,745, p < 0.001) or surgeons (EUR 2,513, p < 0.05). The mean LOS was the variable with highest influence on total cost. Patients cared for by gastroenterologists had a mean LOS significantly shorter (7.3 days) than that of those treated by internists (16.2 days, p < 0.001) or surgeons (11 days, p < 0.001). Hospital costs and LOS differences were maintained when adjusting for severity of illness. In caring for low risk patients, nongastroenterologists had a higher probability of having a hospital stay longer than 4 days (odds ratio = 18.4, Cl = 4.6-73.6, p < 0.001). CONCLUSION: The implementation of specific evidence-based protocols by gastroenterologists reduces length of hospital stay and saves medical costs in patients with nonvariceal UGIB, especially those at low risk.
