"Clandestine" home delivery with mifepristone.

Denial of pregnancy is a rare psychic process associated with an increased risk of infant death. Forensic examinations to determine viability at birth can heavily influence the legal proceedings in cases of clandestine deliveries that result in the death of the infant. A 32-year-old woman who experienced a denial of pregnancy up to 30 weeks of amenorrhea reported giving birth at home at an estimated term of 35 weeks of amenorrhea.

Lack of everolimus diffusion in pleural fluid during pleural progression of breast cancer: A case report.

Background: We report here a case where no everolimus pleural diffusion was evidenced at the same time of pleural progression of a metastatic breast cancer treated with everolimus and exemestane.

Case Description: A 69-year-old woman was diagnosed in October 2006 with stage III invasive ductal breast adenocarcinoma. After nine months of everolimus and exemestane treatment, she presented with a pleural progression.

Sudden Death by Spontaneous Epiglottic Hematoma Secondary to High Blood Levels of Warfarin.

A 67-year-old man was found dead, at his home. On external examination, we found a voluminous purplish black ecchymosis of the anterior neck area. On internal examination, we found a voluminous epiglottis hematoma completely obstructing the upper airway.

Accuracy in obtaining 100 μg from 10 mg of morphine for spinal anesthesia.

Study Objective: Dilution is often required to obtain appropriate concentrations of intrathecal morphine for analgesia. We compared techniques of diluting by measuring the quantity of morphine actually obtained in the final solution.

Design: This is an experimental study by 3 experienced anesthesiologists.

In vivo efficacy of ceftaroline fosamil in a methicillin-resistant panton-valentine leukocidin-producing Staphylococcus aureus rabbit pneumonia model.

Ceftaroline, the active metabolite of the prodrug ceftaroline fosamil, is a cephalosporin with broad-spectrum in vitro activity against Gram-positive organisms, including methicillin-resistant Staphylococcus aureus (MRSA) and multidrug-resistant Streptococcus pneumoniae (MDRSP), and common Gram-negative pathogens. This study investigated the in vivo activity of ceftaroline fosamil compared with clindamycin, linezolid, and vancomycin in a severe pneumonia model due to MRSA-producing Panton-Valentine leukocidin (PVL). A USA300 PVL-positive clone was used to induce pneumonia in rabbits.

Celecoxib but not the combination of celecoxib+atorvastatin prevents the development of monocrotaline-induced pulmonary hypertension in the rat.

The present study aimed to assess the effects of a COX-2 inhibitor, celecoxib, a HMG-CoA reductase inhibitor, atorvastatin, and the association of both on monocrotaline (MC)-induced pulmonary hypertension in rats. Celecoxib (Cib, 25 mg kg(-1) day(-1)), atorvastatin (AS, 10 mg kg(-1) day(-1)) or vehicle, were given orally, separately or in combination, for 26 days to Wistar male rats injected or not with MC (60 mg/kg intraperitoneally). At 4 weeks, MC-injected rats developed a severe pulmonary hypertension, with an increase in lung to body weight ratio (L/BW), right ventricular pressure (RVP in mmHg, 31 +/- 3 and 14 +/- 1 for MC and control groups, respectively, P < 0.

The protective effect of HMG-CoA reductase inhibitors against monocrotaline-induced pulmonary hypertension in the rat might not be a class effect: comparison of pravastatin and atorvastatin.

Hydroxymethylglutaryl coenzyme A (HMG-CoA) reductase inhibitors, so called statins, improve endothelial function and exert antiproliferative effects on vascular smooth muscle cells of systemic vessels. This study aimed at comparing the protective effects of two statins, pravastatin and atorvastatin, against monocrotaline (MC)-induced pulmonary hypertension in rats. Pravastatin or atorvastatin (PS or AS, 10 mg/kg per day) or vehicle were given orally for 28 days to Wistar male rats injected or not with MC (60 mg/kg intraperitoneally).

The HMG-CoA reductase inhibitor, pravastatin, prevents the development of monocrotaline-induced pulmonary hypertension in the rat through reduction of endothelial cell apoptosis and overexpression of eNOS.

HMG-CoA reductase inhibitors improve endothelial function and exert antiproliferative effects on vascular smooth muscle cells of systemic vessels. This study was aimed to assess the protective effects of pravastatin (an HMG-CoA reductase inhibitor) against monocrotaline-induced pulmonary hypertension in rats. Pravastatin (PS, 10 mg/kg/day) or vehicle were given orally for 28 days to Wistar male rats injected or not with monocrotaline (MC, 60 mg/kg intraperitonealy) and treated or not by N(omega)-nitro-L-arginine methyl ester (L-NAME) 15 mg/kg/day.

Arachidonic acid relaxes human pulmonary arteries through K+ channels and nitric oxide pathways.

We aimed to investigate the role of K(+) channels and nitric oxide (NO) on the relaxant effects of arachidonic acid in the human intralobar pulmonary arteries. Arachidonic acid produced a concentration-dependent relaxation (E(max)=93+/-3% of maximal relaxation induced by papaverine 0.1 mM;-log EC(30)=7.

ETA, mixed ETA/ETB receptor antagonists, and protein kinase C inhibitor prevent acute hypoxic pulmonary vasoconstriction: influence of potassium channels.

The aims of this study were to investigate the effects of a selective ETA (BQ-123), a selective ETB (BQ-788), and a specific mixed ETA/ETB receptor antagonist (bosentan) on the pulmonary vasoconstriction induced by hypoxia in the isolated perfused rat lung, and the role of nitric oxide, adenosine triphosphate-sensitive (KATP), large conductance Ca+-activated (BKCa) and 4-aminopyridine-sensitive voltage-gated K channels (K+) in the relaxant effects of the selective ETA receptor antagonist BQ-123 and a protein kinase C inhibitor, bisindolylmaleimide I. K+ channels were inhibited by glibenclamide, charybdotoxin, and 4-aminopyridine and nitric oxide synthase by L-NG-nitroarginine methyl ester (L-NAME). Hypoxic ventilation produced a significant pressure response (+57%, p < 0.

Relaxant effects of selective phosphodiesterase inhibitors on U46619 precontracted human intralobar pulmonary arteries and role of potassium channels.

We examined the influence of K+ channel antagonists on the vasorelaxation induced by theophylline (non selective PDEI), siguazodan (PDE3I), rolipram (PDE4I) and zaprinast (PDE5I) in human intralobar pulmonary arteries. All PDEI tested induced a concentration-dependent relaxation with theophylline being significantly (p < 0.05) more efficient and rolipram more potent than PDE5I and PDE3I (Emax values, expressed as a percentage of maximal relaxation by papaverine 10(-4)M, were 92% +/- 2%, 84% +/- 8%, 90% +/- 4% and 99% +/- 1%, and pD2 values were 7.
