Pleural fluid cytokines correlate with tissue inflammatory expression in tuberculosis

SETTING: A tertiary care research centre in Sao Paolo, Brazil. OBJECTIVE: To quantify interleukin (IL) 8, tumour necrosis factor alpha (TNF-alpha), vascular endothelial growth factor (VEGF) and transforming growth factor beta(1), (TGF-beta(1))in pleural fluid from tuberculous patients, correlating its values with the histopathological patterns in pleural biopsies. DESIGN: Cytokines were quantified in patients with transudatcs secondary to congestive heart failure (n = 8) and exudates secondary to tuberculosis (TB; n = 39). In parietal pleural biopsies from TB patients, the histological patterns of the inflammatory response were quantified by morphometric analysis (stereological point-counting method). RESULTS: IL-8, TNF-alpha, VEGF and TGF-beta(1) levels were higher in TB than in transudates. A positive correlation existed between components of the fibrinoid exudative phase with pleural fluid IL-8 (R = 0.52, P = 0.004) and VEGF (R = 0.42, P = 0.0021) levels. A negative correlation existed between pleural fluid IL-8 (R = -0.37, P = 0.048) and VEGF (R = -0.44, P = 0.0015) levels with tissue components of fibroproliferation. CONCLUSION: The high pleural levels of TNF-a, IL-8, VEGF and TGF-beta(1) suggest the involvement of these cytokines in the TB immunological response. The positive correlation between pleural fluid IL-8 and VEGF with the components of the acute exudative phase and the negative correlation between these cytokines with the fibroproliferative components suggest a temporary inflammatory response in the pleural space.

Associations of serious mental illness with earnings: results from the WHO World Mental Health surveys

Background Burden-of-illness data, which are often used in setting healthcare policy-spending priorities, are unavailable for mental disorders in most countries. Aims To examine one central aspect of illness burden, the association of serious mental illness with earnings, in the World Health Organization (WHO) World Mental Health (WMH) Surveys. Method The WMH Surveys were carried out in 10 high-income and 9 low- and middle-income countries. The associations of personal earnings with serious mental illness were estimated. Results Respondents with serious mental illness earned on average a third less than median earnings, with no significant between-country differences (chi(2)(9)=5.5-8.1, P=0.5-0.79). These losses are equivalent to 0.3-0.8% of total national earnings. Reduced earnings among those with earnings and the increased probability of not earning are both important components of these associations: Conclusions These results add to a growing body of evidence that mental disorders have high societal costs. Decisions about healthcare resource allocation should take these costs into consideration.

The Prognosis of the Traumatic Subarachnoid Hemorrhage: A Prospective Report of 121 Patients

Recent investigations have shown the significance of subarachnoid bleeding on computed tomography scans first taken after admission for head injuries. In our study, we describe a prospective follow-up of 121 patients with traumatic subarachnoid hemorrhage (tSAH). From January 2004 to January 2007 we collected data prospectively from 121 patients admitted with diagnosis of tSAH to our trauma intensive care unit, on the basis of admission with a computed tomography scan. The classification of tSAH was performed using the Fisher scale with modification, and the follow-up was performed using the Glasgow Outcome Scale (GOS). The minimum period for a follow-up was established 6 months after the injury. Traffic accident was the main cause of head injuries (72% in total; 48% involving cars and 24% involving motorcycles), followed by falls (23%) and aggression (5%). Twenty-eight percent of patients sustained major multiple injuries, with spinal injury as the main associated trauma. The outcome was favorable (GOS score 4 or 5) in 54 patients (45%) and unfavorable (GOS score 1, 2, or 3) in 67 patients (55%). The mortality rate was proportionally greater in patients who had cisternal clots >1 mm (P < 0.001), assessed by the Fisher scale with modification. When functional recovery was evaluated using the GOS, the recovery rate and the daily life activities were lower in patients with intraventricular bleeding (P = 0.001). Our results showed that patients with severe tSAH had the worst prognosis.

Short- and long-term survival of patients with metastatic solid cancer admitted to the intensive care unit: prognostic factors

Decisions for intensive care unit (ICU) admissions in patients with advanced cancer are complex, and the knowledge of survival rates and prognostic factors are essential to these decisions. Ours objectives were to describe the short- and long-term survival of patients with metastatic solid cancer admitted to an ICU due to emergencies and to study the prognostic factors presented at ICU admission that could be associated with hospital mortality. We retrospectively analysed the charts of all patients with metastatic solid cancer admitted over a 1-year period. This gave a study sample of 83 patients. The ICU, hospital, 1-year and 2-year survival rates were 55.4%, 28.9%, 12.0% and 2.4% respectively. Thrombocytopenia (odds ratio 26.2; P = 0.006) and simplified acute physiology score (SAPS II) (odds ratio 1.09; P = 0.026) were independent factors associated with higher hospital mortality. In conclusion, the survival rates of patients with metastatic solid cancer admitted to the ICU due to emergencies were low, but of the same magnitude as other groups of cancer patients admitted to the ICU. The SAPS II score and thrombocytopenia on admission were associated with higher hospital mortality. The characteristics of the metastatic disease, such as number of organs with metastasis and central nervous system metastasis were not associated with the hospital mortality.

Comparative Prevalence, Correlates of Impairment, and Service Utilization for Eating Disorders Across US Ethnic Groups: Implications for Reducing Ethnic Disparities in Health Care Access for Eating Disorders

Objective: The study compared the prevalence, correlates of functional impairment, and service utilization for eating disorders across Latinos, Asians, and African Americans living in the United States to non-Latino Whites. Method: Pooled data from the NIMH Collaborative Psychiatric Epidemiological Studies (CPES; NIMH, 2007) were used. Results: The prevalence of anorexia nervosa (AN) and binge-eating disorder (BED) were similar across all groups examined, but bulimia nervosa (BN) was more prevalent among Latinos and African Americans than non-Latino Whites. Despite similar prevalence of BED among ethnic groups examined, lifetime prevalence of any binge eating (ABE) was greater among each of the ethnic minority groups in comparison to non-Latino Whites. Lifetime prevalence of mental health service utilization was lower among ethnic minority groups studied than for non-Latino Whites for respondents with a lifetime history of any eating disorder. Discussion: These findings suggest the need for clinician training and health policy interventions to achieve optimal and equitable care for eating disorders across all ethnic groups in the United States.

Response to AIDS in Brazil: contributions of social movements and the sanitary reform

This paper briefly outlines how the political scenario and the mobilization of different actors have contributed to the construction of a public health policy in response to the AIDS epidemics in Brazil. Three factors are presented and discussed: the political context of the 1980s, characterized by redemocratization, growth of social movements, and consolidation of the Brazilian health care reform; the socio-cultural context of the 1970s and 1980s, characterized by achievement of individual freedom, which was key to the organization of the AIDS movement; and finally the actions carried out in the international scenario to support the sustainability of the Brazilian domestic policy and the reinforcement of a global response to face the epidemics in lower-middle income economies.

Benefit of antiretroviral therapy on survival of human immunodeficiency virus-infected patients admitted to an intensive care unit

Objective: To evaluate the impact of antiretroviral therapy (ART) and the prognostic factors for in-intensive care unit (ICU) and 6-month mortality in human immunodeficiency virus (HIV)-infected patients. Design: A retrospective cohort study was conducted in patients admitted to the ICU from 1996 through 2006. The follow-up period extended for 6 months after ICU admission. Setting: The ICU of a tertiary-care teaching hospital at the Universidade de Sao Paulo, Brazil. Participants: A total of 278 HIV-infected patients admitted to the ICU were selected. We excluded ICU readmissions (37), ICU admissions who stayed less than 24 hours (44), and patients with unavailable medical charts (36). Outcome Measure: In-ICU and 6-month mortality. Main Results: Multivariate logistic regression analysis and Cox proportional hazards models demonstrated that the variables associated with in-ICU and 6-month mortality were sepsis as the cause of admission (odds ratio [OR] = 3.16 [95% confidence interval [CI] 1.65-6.06]); hazards ratio [HR] = 1.37 [95% Cl 1.01-1.88)), an Acute Physiology and Chronic Health Evaluation 11 score >19 [OR = 2.81 (95% CI 1.57-5.04); HR = 2.18 (95% CI 1.62-2.94)], mechanical ventilation during the first 24 hours [OR = 3.92 (95% CI 2.20-6.96); HR = 2.25 (95% CI 1.65-3.07)], and year of ICU admission [OR = 0.90 (95% CI 0.81-0.99); HR = 0.92 [95% CI 0.87-0.97)]. CD4 T-cell count <50 cells/mm(3) Was only associated with ICU mortality [OR = 2.10 (95% Cl 1.17-3.76)]. The use of ART in the ICU was negatively predictive of 6-month mortality in the Cox model [HR = 0.50 (95% CI 0.35-0.71)], especially if this therapy was introduced during the first 4 days of admission to the ICU [HR = 0.58 (95% CI 0.41-0.83)]. Regarding HIV-infected patients admitted to ICU without using ART, those who have started this treatment during ICU, stay presented a better prognosis when time and potential confounding factors were adjusted for [HR 0.55 (95% CI 0.31-0.98)]. Conclusions: The ICU outcome of HIV-infected patients seems to be dependent not only on acute illness severity, but also on the administration of antiretroviral treatment.

HANDEDNESS INFLUENCES PASSIVE SHOULDER RANGE OF MOTION IN NONATHLETE ADULT WOMEN

Objective: The Purpose of this study was to determine whether handedness influences bilateral shoulder range of motion in nonathlete adult women. Methods: This was an observational Study. Shoulder range of motion (flexion, abduction, horizontal adduction, extension, external and internal rotation) was passively and bilaterally measured in 50 female, right-handed, and healthy university students, ranging from 20 to 29 years of age, who were not practicing repetitive activities with the upper limbs at the time Of this study. The assessment was performed with a universal goniometer, twice for each subject by the same examiner. irst and second measurements were correlated using the intraclass correlation coefficient, which was high for all movements and ranged from 0.80 to 0.97. The Student t test and Wilcoxon test were used to compare the range of motion between the dominant and nondominant shoulders and the mean differences between the 2 sides. The effect of size vias alpha = .05. Results: There is statistically significance difference between the 2 sides when the rotational range of motion is compared the dominant shoulder presented increased external rotation (mean, 4.74 degrees; 95% confidence interval, 1.61-7.87) and decreased internal rotation (mean, 3.52 degrees; 95% confidence interval, 1.64-5.4) compared to the opposite Shoulder. Conclusion: Dominance should be considered when shoulder rotation is evaluated even in nonathlete adult women. (J Manipulative Physiol Ther 2009;32:149-153)

Psoriasis in childhood and adolescence

Psoriasis is a chronic, immunologically mediated, recurrent and universal inflammatory disorder. Approximately one third of adults refer onset before 16 years of age. The sooner the onset, the worse is the prognosis. In children, lesions may be physically disfiguring, leading to psychological impairment and evident loss of quality of life. Systemic therapy used in psoriasis, as well as phototherapy, has limited use in children due to accumulative effects of drugs, low acceptance, and risk of teratogenicity. In this section, we discuss the main clinical aspects of psoriasis in childhood and adolescence. differential diagnosis, therapeutic options, and prognosis.

Evolutive physicochemical characterization of diabetic ketoacidosis in adult patients admitted to the intensive care unit

Purpose: The aim of this study was to characterize the first 48-hour evolution of metabolic acidosis of adult patients with diabetic ketoacidosis admitted to the intensive care unit. Materials and Methods: We studied 9 patients retrieved from our prospective collected database, using the physicochemical approach to acid-base disturbances. Results: Mean (SD) age was 34 (13) years; mean (SD) Acute Physiology and Chronic Health Evaluation II score was 16 (10); mean (SD) blood glucose level on admission was 480 (144) mg/dL; mean (SD) pH was 7.17 (0.18); and mean (SD) standard base excess was -16.8 (7.7) mEq/L. On admission, a great part of metabolic acidosis was attributed to unmeasured anions (strong ion gap [SIG], 20 +/- 10 mEq/L), with a wide range of strong ion difference (41 +/- 10 mEq/L). During the first 48 hours of treatment, 297 +/- 180 IU of insulin and 9240 +/- 6505 mL of fluids were used. Metabolic improvement was marked by the normalization of pH, partial correction of standard base excess, and a reduction of hyperglycemia. There was a significant improvement of SIG (7.6 +/- 6.2 mEq/L) and a worsening of strong ion difference acidosis (36 +/- 5 mEq/L) in the first 24 hours, with a trend toward recuperation between 24 and 48 hours (38 +/- 6 mEq/L). Conclusion: Initial metabolic acidosis was due to SIG, and the treatment was associated with a significant decrease of SIG with an elevation of serum chloride above the normal range.

Homeopathic practice in Intensive Care Units: objective semiology, symptom selection and a series of sepsis cases

Homeopathy has been used for more than two hundred years to treat chronic disease using various approaches in a wide range of diseases. However, for acute disease and critical illness, application has been limited by inadequate training of homeopathic physicians and the small number of pertinent clinical studies. In view of the difficulty of practising homeopathy in Intensive Care Units (ICU), a protocol was developed to facilitate description of objective homeopathic symptoms with a ranking of symptoms appropriate for these situations (Protocol for Objective Homeopathic Semiology). Examples of favorable results with individualized homeopathic treatments for a series of cases of Systemic Inflammatory Response Syndrome (sepsis) are described. Homeopathy (2008) 97, 206-213.
