Clinical characteristics and outcome of infective endocarditis involving implantable cardiac devices.

CONTEXT: Infection of implantable cardiac devices is an emerging disease with significant morbidity, mortality, and health care costs. OBJECTIVES: To describe the clinical characteristics and outcome of cardiac device infective endocarditis (CDIE) with attention to its health care association and to evaluate the association between device removal during index hospitalization and outcome. DESIGN, SETTING, AND PATIENTS: Prospective cohort study using data from the International Collaboration on Endocarditis-Prospective Cohort Study (ICE-PCS), conducted June 2000 through August 2006 in 61 centers in 28 countries. Patients were hospitalized adults with definite endocarditis as defined by modified Duke endocarditis criteria. MAIN OUTCOME MEASURES: In-hospital and 1-year mortality. RESULTS: CDIE was diagnosed in 177 (6.4% [95% CI, 5.5%-7.4%]) of a total cohort of 2760 patients with definite infective endocarditis. The clinical profile of CDIE included advanced patient age (median, 71.2 years [interquartile range, 59.8-77.6]); causation by staphylococci (62 [35.0% {95% CI, 28.0%-42.5%}] Staphylococcus aureus and 56 [31.6% {95% CI, 24.9%-39.0%}] coagulase-negative staphylococci); and a high prevalence of health care-associated infection (81 [45.8% {95% CI, 38.3%-53.4%}]). There was coexisting valve involvement in 66 (37.3% [95% CI, 30.2%-44.9%]) patients, predominantly tricuspid valve infection (43/177 [24.3%]), with associated higher mortality. In-hospital and 1-year mortality rates were 14.7% (26/177 [95% CI, 9.8%-20.8%]) and 23.2% (41/177 [95% CI, 17.2%-30.1%]), respectively. Proportional hazards regression analysis showed a survival benefit at 1 year for device removal during the initial hospitalization (28/141 patients [19.9%] who underwent device removal during the index hospitalization had died at 1 year, vs 13/34 [38.2%] who did not undergo device removal; hazard ratio, 0.42 [95% CI, 0.22-0.82]). CONCLUSIONS: Among patients with CDIE, the rate of concomitant valve infection is high, as is mortality, particularly if there is valve involvement. Early device removal is associated with improved survival at 1 year.

Clinical outcome after trimipramine in patients with delusional depression - a pilot study

The treatment of delusional depression is a major challenge in psychopharmacology. Hypothalamic-pituitary-adrenocortical (HPA) overdrive may contribute, via increased dopaminergic activity, to the pathophysiology of the disorder. Trimipramine appears to be an interesting potential candidate, since it is an atypical antidepressant that is known to inhibit HPA activity. In a four-week open trial we investigated its effects in 15 inpatients with delusional depression. The dosage was increased within 7 days up to 300 - 400 mg/d and was then maintained for three weeks. Psychometric assessments and safety monitoring were conducted weekly. Assessment of the HPA activity was achieved by a combined dexamethasone suppression/corticotropin-releasing hormone stimulation (Dex/CRH) test before and after four weeks of treatment. Therapeutic response was defined as a decrease in the HAMD-score of at least 50 %. Eight out of 13 completers were rated as responders. Therapeutic response was associated with L, D-trimipramine concentrations higher than 160 ng/ml. Intent-to-treat analysis showed significant improvement in psychometric variables. Despite the high dosage, the substance was generally well tolerated, with the exception of one patient who suffered from a hypotensive reaction. Mean +/- SD concentration of L-trimipramine and D-trimipramine were 138 +/- 61 ng/ml and 119 +/- 50 ng/ml at a final dose of 346 +/- 50 mg/d. The ACTH and cortisol area under the curve in the Dex/CRH tests decreased significantly, reflecting a decrease of activity in the HPA system. We suggest that the clinical use of high-dose trimipramine in delusional depression seems to be a promising treatment strategy.

Congenital hydrocephalus--prevalence, prenatal diagnosis and outcome of pregnancy in four European regions.

OBJECTIVE: To describe prevalence, prenatal diagnosis and outcome for fetuses and infants with congenital hydrocephalus. METHODS: Data were taken from four European registries of congenital malformations (EUROCAT). The registries included are based on multiple sources of information and include information about livebirths, fetal deaths with GA > or = 20 weeks and terminations of pregnancy for fetal anomaly (TOPFA). All cases from the four registries diagnosed with congenital hydrocephalus and born in the period 1996-2003 were included in the study. Cases with hydrocephalus associated with neural tube defects were not included in the study. RESULTS: Eighty-seven cases with congenital hydrocephalus were identified during the study period giving an overall prevalence of 4.65 per 10,000 births. There were 41 livebirths (47%), four fetal deaths (5%) and 42 TOPFA (48%). Nine percent of all cases were from a multiple pregnancy. Additional non-cerebral major malformations were diagnosed in 38 cases (44%) and karyotype anomalies in eight cases (9%). Median GA at TOPFA was 21 weeks. Among livebirths 61% were diagnosed prenatally at a median GA of 31 weeks (range 17-40 weeks) and median GA at birth was 37 weeks. Fourteen liveborn infants (34%) died within the first year of life with the majority of deaths during the first week after birth. CONCLUSION: Congenital hydrocephalus is a severe congenital malformation often associated with other congenital anomalies. CH is often diagnosed prenatally, although sometimes late in pregnancy. A high proportion of affected pregnancies result in termination for severe fetal anomaly and there is a high mortality in livebirths.

Pregnancy outcome following maternal exposure to statins: a multicenter prospective study

Introduction Statin use in women of childbearing age is increasingly common. However, published data on pregnancy outcome after exposure to statins are scarce and conflicting. This contribution addresses the safety of statin use during pregnancy.Materials and Methods In a multi-centre (n = 11), prospective study we compared the outcomes of 249 women exposed during the 1st trimester of pregnancy to simvastatin (n = 124), atorvastatin (n = 67), pravastatin (n = 32), rosuvastatin (n = 18), fl uvastatin (n = 7) or cerivastatin (n = 1) with a control group exposed to agents known to be non-teratogenic (n = 249). Data were collected by members of the European Network of Teratology Information Services during individual risk counselling.Results The difference in the rate of major birth defects between the statinexposed and the control group was statistically insignificant (4.0% versus 2.7% OR 1.5; 95% CI 0.5-4.5, p = 0.44). The crude rate of spontaneous abortions (12.8% versus 7.1%, OR 1.9, 95% CI 1.0-3.6, p = 0.04) was higher in the exposed group. However, after adjustment to maternal age and gestational age at initial contact, the difference became insignificant. The rate of elective pregnancy-termination (8.8% versus 4.4%, p = 0.05) was higher and the rate of live births was lower in the exposed group (77.9% versus 88.4%, p = 0.002). Prematurity was more frequent in exposed pregnancies (16.1% versus 8.5%; OR 2.1, 95% CI 1.1- 3.8, p = 0.02). Nonetheless, gestational age at birth (median 39 weeks, IQR 37-40 versus 39 weeks, IQR 38-40, p = 0.27) and birth weight (median 3280 g, IQR 2835-3590 versus 3250 g, IQR 2880- 3600, p = 0.95) did not differ between exposed and non-exposed pregnancies.Conclusion This study did not detect a teratogenic effect of statins. Its statistical power however is not sufficient to reverse the recommendation of treatment discontinuation during pregnancy.

Factors affecting cognitive outcome in early pediatric stroke.

OBJECTIVE: We examined cognitive performance in children after stroke to study the influence of age at stroke, seizures, lesion characteristics, neurologic impairment (NI), and functional outcome on cognitive outcome. METHODS: This was a prospectively designed study conducted in 99 children who sustained an arterial ischemic stroke (AIS) between the age of 1 month and 16 years. All children underwent cognitive and neurologic follow-up examination sessions 2 years after the insult. Cognitive development was assessed with age-appropriate instruments. RESULTS: Although mean cognitive performance was in the lower normative range, we found poorer results in subtests measuring visuoconstructive skills, short-term memory, and processing speed. Risk factors for negative cognitive outcome were young age at stroke, seizures, combined lesion location (cortical and subcortical), as well as marked NI. CONCLUSIONS: We recommend that all children with a history of AIS undergo regularly scheduled neuropsychological assessment to ensure implementation of appropriate interventions and environmental adjustments as early as possible.

Early clinical experience with ranibizumab for occult and minimally classic neovascular membranes in age-related macular degeneration.

BACKGROUND: In large randomized multicenter trials, ranibizumab has shown its therapeutic efficacy for exudative age-related macular degeneration (AMD). The aim of this paper is to report the real-life clinical experience with this treatment for occult and minimally classic membranes without pigment epithelium detachment. METHODS: We conducted a retrospective chart review of 37 patients with occult and minimally classic neovascular membranes in AMD, without pigment epithelium detachment. RESULTS: The mean visual improvement of 2 lines at 3, 6 and 9 months corresponds well with the results of the large trials. A mean number of 5 reinjections was reached by month 8. It may potentially exceed the mean 5.5 injections of the PrONTO study (prospective optical coherence tomography imaging of patients with neovascular AMD treated with intraocular ranibizumab). At months 6-8 recurrence was frequently observed. CONCLUSION: The early experience of ranibizumab in clinical practice brings similarly good results as the large-scale trials. However, interrupting the treatment too early may be a disadvantage.

Anatomic and functional outcome after 23-gauge sutureless transconjunctival vitrectomy, peeling and intravitreal triamcinolone for idiopathic macular epiretinal membranes

Purpose:To report the functional, anatomic outcome and safety profile of 23-gauge pars plana vitrectomy (PPV) combined with peeling and intravitreal injection of triamcinolone acetonide (TA) in eyes with idiopathic epiretinal membranes (ERM). Methods:Retrospective, nonrandomized study of consecutive patients who underwent 23-gauge transconjunctival sutureless PPV with subsequent membrane peeling and intravitreal TA injection for an idiopathic ERM. All patients were operated between February 2007 and February 2008 at the Jules Gonin University Eye Hospital. The minimum follow-up was 6-months. Results:Thirty-nine eyes of 39 patients were included. The mean follow-up was 7 months (SD: 2.2, range: 6-15 months). Twenty-two (56%) eyes were pseudophakic and 17 (44%) were phakic at the time of surgery. Mean preoperative intraocular pressure (IOP) was 14 mmHg (SD: 3.5). At the final follow-up mean IOP was 14.5 (SD: 2.7) that did not differ significantly from the IOP at baseline (P: 0.14- 2-tailed t test). Five patients (13%) needed temporary topical anti-glaucoma treatment.Mean preoperative BCVA was 0.28 decimal equivalent (logMAR 0.54, SD: 0.2, range: 1.0 - 0.2). and improved significantly (P <0.0001, 2-tailed t test) to a mean of 0.6 decimal equivalent (logMAR 0.22, SD: 0.16, range: 0.6 - 0) at the final follow-up. The visual acuity improved by a mean of 3.2 lines (SD 2.1, range 0- 8). Twenty-nine patients (74%) demonstrated a gain of 3 or more lines.Mean central macular thickness (CMT) was 456 µm (SD: 77) at the baseline that reduced significantly (P <0.0001, 2-tailed t test) at the final follow-up to 327µm (SD: 79). Average CMT reduction was 131µm (SD: 77, range: 36- 380 µm). A subgroup analysis of 15 selected cases that had CMT measurement 1 week after surgery demonstrated that 84% of the total final reduction in CMT occurred during the first week. Conclusions:23-gauge sutureless transconjunctival vitrectomy with the concomitant administration of intravitreal TA is a safe and effective technique for the treatment of idiopathic ERM and may speed up anatomical recovery.

Predicting outcome after acute basilar artery occlusion based on admission characteristics.

OBJECTIVE: To develop a simple prognostic model to predict outcome at 1 month after acute basilar artery occlusion (BAO) with readily available predictors. METHODS: The Basilar Artery International Cooperation Study (BASICS) is a prospective, observational, international registry of consecutive patients who presented with an acute symptomatic and radiologically confirmed BAO. We considered predictors available at hospital admission in multivariable logistic regression models to predict poor outcome (modified Rankin Scale [mRS] score 4-5 or death) at 1 month. We used receiver operator characteristic curves to assess the discriminatory performance of the models. RESULTS: Of the 619 patients, 429 (69%) had a poor outcome at 1 month: 74 (12%) had a mRS score of 4, 115 (19%) had a mRS score of 5, and 240 (39%) had died. The main predictors of poor outcome were older age, absence of hyperlipidemia, presence of prodromal minor stroke, higher NIH Stroke Scale (NIHSS) score, and longer time to treatment. A prognostic model that combined demographic data and stroke risk factors had an area under the receiver operating characteristic curve (AUC) of 0.64. This performance improved by including findings from the neurologic examination (AUC 0.79) and CT imaging (AUC 0.80). A risk chart showed predictions of poor outcome at 1 month varying from 25 to 96%. CONCLUSION: Poor outcome after BAO can be reliably predicted by a simple model that includes older age, absence of hyperlipidemia, presence of prodromal minor stroke, higher NIHSS score, and longer time to treatment.

Isolated congenital atrioventricular block diagnosed in utero: natural history and outcome.

BACKGROUND: Isolated congenital atrioventricular block (CAVB) diagnosed in utero is associated with a high morbidity and mortality. Prognosis is especially poor when heart rate drops below 55 beats per minute (bpm) and when fetal hydrops develops. We describe the natural history and outcome of 24 infants with isolated CAVB diagnosed in utero, review the literature, and assess the risk factors that could predict outcome. METHODS: This was a retrospective multicenter study of 24 patients with isolated CAVB diagnosed in utero. RESULTS: CAVB was detected at a mean gestational age (GA) of 24.7 +/- 5.1 weeks. Ten fetuses initially presented with complete heart block. Low heart rate or incomplete heart block was the first documentation of bradyarrhythmia in the other 14 fetuses. In 11 of them, CAVB developed during pregnancy after a median time of 3 (range 1-16) weeks. Fetal hydrops developed in 10 of 24 (42%) fetuses at a mean GA of 27.6 +/- 5.1 weeks. Hydropic fetuses showed lower heart rates during pregnancy (47 +/- 10 bpm) than non-hydropic fetuses (57 +/- 10 bpm). There were three intrauterine deaths; all were hydropic and female. Nine viable females and 12 males were born at a mean GA of 37.1 +/- 6.1 weeks with an average birth weight of 3097 +/- 852 g. Fifteen CAVB patients required pacemaker (PM) intervention, 10 of them immediately after birth. Dilated cardiomyopathy (DCM) developed in three infants of whom two died of congestive heart failure, shortly after the diagnosis was made; one is still alive. Mortality before or after birth was 21%, and was associated with heart rates below 50 bpm and development of fetal hydrops. Poor outcome, defined as death, PM implantation, or development of DCM, occurred in 83% of cases and was associated with heart rates below 60 bpm during pregnancy. CONCLUSIONS: Isolated CAVB diagnosed in utero is associated with high morbidity and mortality. Patients who develop fetal hydrops show lower heart rates during pregnancy than patients who do not. A fetal heart rate below 50 bpm and development of fetal hydrops is associated with increased mortality. Rates below 60 bpm are associated with PM requirement and/or DCM.

Number of transferred embryos: how to reduce multiple pregnancies.

Because the diagnostic tools for predicting whether an early cleavage stage embryo can lead to a viable pregnancy are still elusive, transfer of more than one embryo remains quite common. However, the only way to reduce multiple pregnancies, considered as the main adverse effect of assisted reproductive technology, is to transfer a single embryo. In countries such as Switzerland and Germany, the law allows cryopreservation only at the 2-pronuclear stage. This restricts considerably the possibility of selecting the embryos to be transferred. Therefore, a good cryopreservation program at the 2-pronuclear stage is an essential tool to optimize the efficiency of in vitro fertilization (IVF). We therefore recommend the Cumulated Singleton Delivery Rate (CUSIDERA) as a measure of standard IVF efficiency. This rate averages approximately 23.5% when calculated over the last 10 years in our unit and reaches a value above 35% for patients with more than 10 zygotes. Elective single-embryo transfers and the decrease of iatrogenic multiple pregnancies in IVF remain dependent on better prognostic tools for the appropriate selection of patients, gametes, and zygotes.
