Refractive lens exchange with an array multifocal intraocular lens.

2002

ABSTRACT PURPOSE: To prospectively evaluate safety, efficacy, predictability, stability, complications, and patient satisfaction after refractive lens exchange (clear lens extraction) followed by posterior chamber implantation of a multifocal intraocular lens (IOL). METHODS: Fifty eyes of 25 patients (mean age 51 years, range 44 to 62 years) with preoperative spherical equivalent refraction between -15.50 and +5.75 D and cylinder between 0 and 1.50 D underwent bilateral implantation of a zonal progressive multifocal IOL (Array, AMO). RESULTS: Eyes were divided into group A (n=24; myopia, average preoperative spherical equivalent refraction -7.11 ± 3.25 D (-1.75 to -15.50 D), and group B (n=…

Iris-fixated toric phakic intraocular lens: Three-year follow-up

2006

Purpose To evaluate the 3-year safety, efficacy, predictability, and stability of iris-fixated toric phakic intraocular lens (pIOL) implantation for the correction of myopia or hyperopia with astigmatism. Setting Department of Ophthalmology, Johannes Gutenberg University, Mainz, and Department of Ophthalmology, University Clinic, Bochum, Germany. Methods A prospective clinical trial of 40 eyes of 23 patients with high ametropia and astigmatism was conducted. Best spectacle-corrected visual acuity (BSCVA), uncorrected visual acuity, refraction, astigmatism, intraocular pressure, slitlamp biomicroscopy, and indirect ophthalmoscopy were measured preoperatively and postoperatively. Results Of t…

Systemic chemotherapy and pressurized intraperitoneal aerosol chemotherapy (PIPAC): A bidirectional approach for gastric cancer peritoneal metastasis

2019

Abstract Background Few patients affected by gastric cancer peritoneal metastasis (GCPM) are offered locoregional treatment, despite several proof-of-efficacy trials. Pressurized intraperitoneal aerosol chemotherapy (PIPAC) has emerged in recent years as a promising tool to control peritoneal carcinomatosis. The combination of PIPAC with systemic chemotherapy may offer a greater clinical benefit than standard treatment alone. Methods A single-center cohort of 28 consecutive patients affected by GCPM was scheduled for bidirectional treatment, comprising PIPAC and systemic chemotherapy, from September 2017 to September 2019. Data recorded included safety, efficacy and survival outcomes. Ascit…

Improvement of heart iron with preserved patterns of iron store by CMR-guided chelation therapy

2014

[Formula: see text] multislice multiecho cardiac magnetic resonance (CMR) allows quantification of the segmental distribution of myocardial iron overload (MIO). We evaluated whether a preferential pattern MIO was preserved between two CMR scans in regularly chelated thalassaemia major (TM) patients.We evaluated prospectively 259 TM patients enrolled in the MIO in Thalassaemia (MIOT) network with a CMR follow-up (FU) study at 18 ± 3 months and significant MIO at baseline. The [Formula: see text] in the 16 segments and the global value were calculated. Four main circumferential regions (anterior, septal, inferior and lateral) were defined. We identified two groups: severe (n = 80, global [For…

Phase IV open-label study of the efficacy and safety of deferasirox after allogeneic stem cell transplantation

2014

This is the first prospective study of deferasirox in adult allogeneic hematopoietic stem cell transplant recipients with transfusional iron overload in hematologic malignancies. Patients at least six months post transplant were treated with deferasirox at a starting dose of 10 mg/kg/day for 52 weeks or until serum ferritin was less than 400 ng/mL on two consecutive occasions. Thirty patients were enrolled and 22 completed the study. A significant reduction from baseline in median serum ferritin and in liver iron concentration at 52 weeks was observed in the overall population: from 1440 to 755.5 ng/mL (P=0.002) and from 14.5 to 4.6 mg Fe/g dw (P=0.0007), respectively. Reduction in serum fe…

[Prognostic value of interleukin 6 for death of patients with sepsis].

2016

Abstract Background and objective To see the influence of interlukin-6 (IL-6) as an inflammatory mediator in patients with systemic inflammatory response syndrome (SIRS) and sepsis, assessing whether their serum levels during their stay in intensive care unit (ICU) serve as an early mortality prognostic marker. Material and methods A prospective observational cohort study with 203 ICU patients from a third level hospital. A descriptive analysis was made, X 2 test used to compare qualitative variables, T -Student test to compare quantitative ones. We made a logistic regression multivariant analysis on admission, third and seventh day of stay with dependent variable mortality and independent …

Long-Term Follow-Up of Patients with Chronic Hepatitis C after Interferon-Alpha Treatment

1996

In this study, 72 patients with chronic hepatitis C virus (HCV) were followed prospectively for a mean period of 27 months after interferon treatment. Fifty-seven percent (20/35) of the patients with complete response, 18/20 with HCV-RNA-negative serum, had a sustained biochemical remission. Reactivation was seen in 43% of these patients after a mean follow-up of 7.3 months. A late relapse after more than 12 months of follow-up occurred in only 2/15 patients. Patients with a long-term complete response had significantly lower pretreatment serum HCV RNA levels than complete responders with relapse (106,239 vs. 345,649 mEq/ml, p = 0.0213). A delayed sustained biochemical remission was seen in…

Hereditary Angioedema: Long-Term Treatment with One or More Injections of C1 Inhibitor Concentrate per Week

2009

<i>Background:</i> Hereditary angioedema due to C1 inhibitor deficiency (HAE-C1-INH) is characterized by recurrent edema attacks in various organs. The objective of the present study was to assess the efficacy and safety of weekly long-term replacement treatment with one or more injections of plasma-derived C1-INH concentrate per week (WLTC) in patients with HAE-C1-INH. <i>Methods:</i> Nineteen patients with HAE-C1-INH underwent WLTC for 9 years on average. The benefits and risks were determined based on regular recording by the patients of the severity and number of attacks at the beginning and the end of the study. <i>Results:</i> All patients reported …

Normal reference values of multilayer longitudinal strain according to age decades in a healthy population: A single-centre experience.

2017

Aims Recent advancements in echocardiographic technology allow to analyse myocardial strain in multiple layers. Little is known about the impact of age on layer-specific longitudinal strain in healthy subjects. The aim of this study was to analyse the influence of age on multilayer longitudinal strain and establish normal reference values of layer-specific strain according to age decades in a healthy population referring to our echo laboratory using 2D speckle-tracking echocardiography with layer-specific software. Methods and results Two-hundred sixty-six healthy, consecutive subjects (mean age = 39.2 ± 17.5 years, women/men = 137/129), free of cardiovascular risk factors, were enrolled. S…

A prospective study of the precursors to problem drinking in young adulthood.

1994

This study was part of the Jyvaskyla Longitudinal Study on Social Development. The subjects (196 males, 173 females) were studied at age 8, 14 and 26. Three components in drinking habits were obtained at age 26: social, problem and controlled drinking. Moderate to severe problem drinking was obtained for 26% of the men and 1% of the women, and mild problem drinking for 23% of the men and 15% of the women. Problem drinking (defined by the CAGE Questionnaire, arrest for alcohol abuse and other indicators of heavy drinking) was directly accounted for by poor school success at age 14 and, for men, by conduct problems and low anxiety. Variables at age 8 that contributed indirectly to adult probl…
