BACKGROUND: A single course of maternal glucocorticoid treatment is effective in reducing neonatal mortality after preterm birth. However, in animals, maternal glucocorticoid treatment is associated with lifelong hyperglycaemia and hypertension, and impaired nephrogenesis in offspring. Findings from studies in humans on this topic are highly contradictory due to a number of methodologic flaws and renal function after glucocorticoid exposure has never been assessed. OBJECTIVES: To assess in individuals born

The purpose of this research was to evaluate the variables that are suggested to influence the adsorption of the hydrophilic hyaluronic acid (HA) onto the surface of the hydrophobic betamethasone-17-valerate (BV) particles in order to formulate a nebulizable suspension. The adsorption of HA from aqueous solutions (0.04% to 0.16%, w/v) to a fixed BV concentration (0.04%, w/v) under different experimental conditions, was investigated. The method of preparation of HA-BV suspensions involved suspending BV particles either in the hydrated HA solution (method 1) or in water followed by addition of solid HA (method 2). Other variables like the time required for the adsorption to complete and temperature at which adsorption is carried out were studied. The nebulization of the suspensions was tested via an air jet nebulizer connected to a twin stage impinger. In order to improve the nebulization behavior of the optimized suspension, L: -leucine or sodium taurocholate was incorporated in increasing concentrations (0.01-0.04%, w/v). The optimized suspension, having a nebulization efficiency of 33.75%, was achieved following the adsorption of HA (0.1%, w/v) onto BV particles adopting method 2 of preparation and extending for three days at 4 degrees C. Incorporation of either l-leucine or sodium taurocholate significantly decreased the aggregate size of the optimized suspension and consequently caused significant increases in the nebulization efficiency to reach 46.87% and 56.25%, respectively.

Conscious sedation, used with or without peripheral or central blocks, is an elective anesthetic technique used for many outpatient procedures. The aim of this study was to evaluate the effects of a single pre-anesthetic dose of betamethasone (4 mg) on intraoperative and postoperative pain in 380 women, 18 to 75 years old, undergoing gynecologic and obstetric surgery (diagnostic curettage, operative and diagnostic hysteroscopy, conization, minilaparoscopy, cone biopsy, endometrial ablation, assisted reproduction techniques, and induced and therapeutic abortion) in a outpatient service. In this randomized, double-blind, placebo-controlled study, the patients were divided into two equal groups according to a computer-generated randomized list. One group received 4 mg of betamethasone i.v. as a premedication (group B), whereas the placebo group (group P) received only saline. All patients underwent the same sedation, associated with a peripheral block. Pain was evaluated using a 5-point verbal rating scale during surgery, after 2 h, and on discharge. In group B, intraoperative and postoperative pain was significantly less frequent than in group P (P < 0.001). Consequently, fewer women belonging to group B requested additional analgesic drugs during and after surgery (P < 0.01). Patients in group B also experienced a greater degree of satisfaction (P < 0.01). Briefly, a single dose of betamethasone seemed to reduce the incidence and severity of perioperative pain after gynecologic outpatient surgery.

To determine the expression of glucocorticoid metabolizing and action genes in the hippocampus of fetal, neonatal, and adult sheep. Pregnant ewes (or their fetuses) received intramuscular injections of saline or betamethasone (BETA, 0-5 mg/kg) at 104, 111, 118, and/or 125 days of gestation (dG). Hippocampal tissue was collected prior to (75, 84, and 101 dG), during (109 and 116 dG), or after (121, 132, and 146 dG; 6 and 12 postnatal weeks; 3.5 years of age) saline or BETA injections. Hippocampal glucocorticoid receptor (GR), mineralocorticoid receptor (MR), and 11beta-hydroxysteroid dehydrogenase (11betaHSD)1 and 11betaHSD2 mRNA levels were determined using qRT-PCR. Control animals late in gestation demonstrated a decrease in mRNA encoding GR and 11betaHSD1, whereas 11betaHSD2 was undetectable, consistent with a damping of the negative feedback influence of circulating or locally produced cortisol on the hypothalamic-pituitary-adrenal (HPA) axis. BETA-administration had transient effects on fetal GR and MR, and early in postnatal life (12 weeks of age) 11betaHSD1 mRNA was increased. Hippocampal MR mRNA was elevated in adult offspring exposed to either one or four doses of maternal BETA (P
Hypersensitivity reaction to the ingestion of mango flesh.

A 42-year-old woman presented with a hypersensitivity reaction after the ingestion of a small amount of fresh mango gelato. She developed itchy palpable purpuric lesions over her arms, legs, neck and abdomen 4 days after ingestion. The lesions persisted for 5 weeks despite treatment with betamethasone-17 valerate 0.05% ointment and avoidance of mango. Resolution of these lesions was eventually achieved with continuing treatment. The patient denied any prior contact with mango skin but had experienced previous sensitizing reactions to mango flesh. Patch testing was strongly positive to mango skin and mango flesh. Skin-prick testing was negative. This case describes a systemic contact dermatitis to mango flesh, an entity less common than allergic contact dermatitis.

OBJECTIVE: To identify predictors of radiographic progression in a 2-year randomized, double-blind clinical study (CIMESTRA) of patients with early rheumatoid arthritis (RA). METHODS: Early RA patients (N=130) were treated with methotrexate, intra-articular betamethasone and cyclosporine/placebo-cyclosporine. Baseline magnetic resonance imaging (MRI) of the wrist (wrist-only-group:N=130) or MRI of wrist and MCP-joints (wrist+MCP-group:N=89) (OMERACT RAMRIS), x-rays of hands, wrists and forefeet (Sharp/vdHeijde Score (TSS)), disease activity score (DAS28), anti-cyclic-citrullinated-peptide-antibodies (anti-CCP), HLA-DRB1-shared-epitope (SE) and smoking status were assessed. Multiple regression analysis was performed with delta-TSS (0-2 years) as dependent variable, and baseline DAS28, TSS, MRI bone oedema score, MRI synovitis score, MRI erosion score, anti-CCP, smoking, SE, age and gender as explanatory variables. RESULTS: Baseline values: median DAS28: 5.6 (range: 2.4-8.0); anti-CCP positive: 61%; radiographic erosions: 56%. At 2 years: DAS28: 2.0 (0.5-5.7), in DAS-remission: 56%, radiographic progression: 26% (wrist+MCP-group, similar for wrist-only-group). MRI bone oedema score was the only independent predictor of delta-TSS (wrist+MCP-group: coefficient=0.75 (95%CI: 0.56-0.97), p

OBJECTIVE: Churg-Strauss syndrome (CSS) is known as autoimmune vasculitis with peripheral eosinophilia after bronchial asthma and rarely has otological findings. We present a case of CSS with refractory otitis media and discuss the relationship between otological symptoms of CSS and eosinophilic otitis media. CASE REPORT: A 60-year-old woman had suffered from recurrent sinusitis for 8 years, and also otitis media with effusion for 4 months. Eruption with peripheral eosinophilia was found in the lower legs; therefore, she was diagnosed with CSS. She was treated with systemic administration of predonisolone, intratympanic injection of betamethasone, and betamethasone nasal spray; thereafter, eosinophilia, otitis media and sinusitis rapidly improved. CONCLUSION: The features of eosinophilic otitis media are similar to the otological symptoms of CSS. It should be considered whether patients with eosinophilic otitis media have early phase CSS.

Background: Coriander oil is used as an antimicrobial agent and as a natural fragrance. The present study investigated the anti-inflammatory potency of coriander oil in the ultraviolet (UV) erythema test in vivo. Methods: 40 volunteers were enrolled in this monocentric,randomized,placebo-controlled double-blind study.Test areas on the back were irradiated with the 1.5 fold minimal erythema dose UV-B. Subsequently, the test areas were treated under occlusion for 47 hours with a lipolotion containing 0.5% or 1.0% essential coriander oil. Hydrocortisone (1.0%) and betamethasone valerate (0.1%) in the vehicle served as positive controls.The vehicle was used as place-bo.The effect of the test substances on the UV-induced erythema was measured photometrically after 48 hours.Additionally,the skin tolerance of the test preparations was assessed on non-irradiated skin. Results: Compared to placebo, the lipolotion with 0.5% coriander oil significantly reduced the UV-induced erythema, but it was not as effective as hydrocortisone. The skin tolerance of both coriander oil concentrations was excellent. Conclusions: The lipolotion containing coriander oil displayed a mild antiinflammatory effect in this study. It could be useful in the concomitant treatment of inflammatory skin diseases.

BACKGROUND: Topical preparations, high in phosphate, may cause calcification when used on a damaged corneal surface. The knowledge of the phosphate concentration in medications helps to prevent corneal calcifications. Our study gives an overview of the amount of phosphate contained in ophthalmic corticoid preparations. METHODS: Samples of 38 commercially available corticoid preparations were tested. The quantification of phosphate was performed using the molybdate method on a Modular P autoanalyzer. RESULTS: 18 of 38 preparations (47%) had a phosphate concentration above physiological levels (>1.45 mmol/l). It varied greatly, and ranged from less than 0.1 mmol/l (18 preparations) to 62.6 mmol/l. The corticoids that were tested included betamethasone sodium phosphate (18.3-35.5 mmol/l), dexamethasone (0.1-17.6 mmol/l), dexamethasone sodium phosphate (
