Management of Chronic Hand Eczema.

Management of hand eczema is complex because of the broad range of different pathogeneses, courses, and prognoses. Furthermore, the efficacy of most available treatments is not well established and the more severe forms can have a major impact on the patient's quality of life. Patient education, preventive measures, and the use of emollients are the mainstays in the management of hand eczema. High-potency topical corticosteroids are the treatment of choice, with calcineurin inhibitors used for maintenance. Phototherapy or systemic treatments are indicated in patients who do not respond to topical treatments. Switching from topical treatments should not be delayed to avoid sensitizations, time off work, and a negative impact on quality of life. Alitretinoin is the only oral treatment approved for use in chronic hand eczema.

Comorbidity in heart failure. Results of the Spanish RICA Registry.

BACKGROUND: We sought to identify the comorbidities associated with heart failure (HF) in a non-selected cohort of patients, and its influence on mortality and rehospitalization. DESIGN AND METHODS: Data were obtained from the 'Registro de Insuficiencia Cardiaca' (RICA) of the Spanish Society of Internal Medicine. The registry includes patients prospectively admitted in Internal Medicine units for acute HF. Variables included in Charlson Index (ChI) were collected and analysed according to age, gender, left ventricular ejection fraction (LVEF) and Barthel Index. The primary end point of study was the likelihood of rehospitalization and death for any cause during the year after discharge. RESULTS: We included 2051 patients, mean age 78 and 53% females. LVEF was ⩾ 50% in 59.1% of the cohort. There was a high degree of dependency as measured by Barthel Index (14.8 % had an index ≤ 60). Mean ChI was 2.91 (SD ± 2.4). The most frequent comorbidities included in ChI were diabetes mellitus (44.3%), chronic renal impairment (30.8%) and chronic obstructive pulmonary disease (COPD) (27.4%). Age, myocardial infarction, peripheral artery disease, dementia, COPD, chronic renal impairment and diabetes with target-organ damage were all identified as independent prognostic factors for the combined end point of rehospitalization and death at 1 year. However, if multivariate analysis was done including ChI, only this remained as an independent prognostic factor for the combined end point (P < 0.001). CONCLUSIONS: HF is a comorbid condition. ChI is a simple and feasible tool for estimating the burden of comorbidities in such population. We believe that a holistic approach to HF would improve prognosis and the relief the pressure exerted on public health services.

Antibacterial activity of the essential oil from Lippia aff. gracillis.

The essential oil of fresh leaves of Lippia aff. gracillis was analyzed by GC/MS and evaluated for its antibacterial effects. The results showed a moderate antibacterial activity and confirm the traditional uses of L. aff. gracillis.

Different regulation of cardiac and renal corticosteroid receptors in aldosterone-salt treated rats: effect of hypertension and glucocorticoids.

This study analysed the regulation of cardiac mineraloreceptor (MR) and glucoreceptor (GR) in aldosterone-salt treatment (AST). AST causes hypertension, left ventricle (LV) hypertrophy and decreases plasma corticosterone level. Ribonuclease protection assay and Western blot analysis showed a rise of MR mRNA (1.5- and 1.4-fold at day 15 and 30, respectively) and protein levels (1.8- and 4.1-fold at day 30 and 60, respectively) in the LV, but not in either the right ventricle (RV) or in kidney of treated rats. Addition of MR antagonist spironolactone (20 mg/kg/day) for 30 days failed to prevent these changes but was able to reduce AST-induced cardiac fibrosis. Similar hypertension-induced MR upregulations were observed in the LV of AngII-hypertensive rats and of 12-week-old SHR when compared to 4-week-old prehypertensive SHR. AST also enhanced left ventricular GR mRNA (2.0- and 3.0-fold at day 7 and 15, respectively) and protein contents (2.0- and 1.7-fold at day 30 and 60, respectively). In contrast to MR, GR levels were also upregulated in both RV and kidney. Such an upregulation was equally observed at mRNA and protein levels in LV, RV and kidney after adrenalectomy (15 days) and was prevented in both tissues after glucocorticoid replacement (adrenalectomy + dexamethasone at 100 micro g/kg/day for 15 days). Therefore, MR level may be controlled by hemodynamical factors whereas that of GR depends upon glucocorticoids level.

Subtypes of ataques de nervios: the influence of coexisting psychiatric diagnosis.

The current study assesses the relationship between presenting symptomatology of the self-labeled Hispanic popular diagnosis of ataques de nervios and the specific co-morbid psychiatric diagnoses. Hispanic subjects seeking treatment at an anxiety disorders clinic (n = 156) were assessed with a specially designed self-report instrument for both traditional ataque de nervios and panic symptoms, and with structured or semistructured psychiatric interviews for Axis-I disorders. This report focuses on 102 subjects with ataque de nervios who also met criteria for panic disorder, other anxiety disorders, or an affective disorder. Distinct ataque symptom patterns correlated with co-existing panic disorder, affective disorders, or other anxiety disorders. Individuals with both ataque and panic disorder reported the most asphyxia, fear of dying, and increased fear during their ataques. People with ataques who also met criteria for affective disorder reported the most anger, screaming, becoming aggressive, and breaking things during ataques. Ataque positive subjects with other anxiety disorders were less salient for both panic-like and emotional-anger symptoms. The findings suggest that (a) ataque de nervios is a popular label referring to several distinct patterns of loss of emotional control, (b) the type of loss of emotional control is influenced by the associated psychiatric disorder, and (c) ataque symptom patterns may be a useful clinical marker for detecting psychiatric disorders. Further study is needed to examine the relationship between ataque de nervios and psychiatric disorders, as well as the relationship to cultural, demographic, environmental, and personality factors.
