Survival differences between European and US patients with colorectal cancer: role of stage at diagnosis and surgery

2005

Background: Population based colorectal cancer survival among patients diagnosed in 1985–89 was lower in Europe than in the USA (45% v 59% five year relative survival). Aims: To explain this difference in survival using a new analytic approach for patients diagnosed between 1990 and 1991. Subjects: A total of 2492 European and 11 191 US colorectal adenocarcinoma patients registered by 10 European and nine US cancer registries. Methods: We obtained clinical information on disease stage, number of lymph nodes examined, and surgical treatment. We analysed three year relative survival, calculating relative excess risks of death (RERs, referent category US patients) adjusted for age, sex, site, …

Increased amplitudes of distortion product otoacoustic emissions in patients with unilateral acoustic neuroma.

2004

We present a case series of 4 patients with a unilateral acoustic neuroma and increased amplitudes of the distortion products of otoacoustic emissions (DPOAEs) at the low- and middle- frequency bandwidth on the involved side compared to the uninvolved side despite a 28-dB hearing level (HL) worse (compared to the uninvolved side) pure-tone hearing threshold average for standard audiometric frequencies between 1 and 6 kHz at the involved side. In 3 of these patients, 2 with an inferior vestibular nerve origin of the acoustic neuroma and one in whom the nerve of origin could not be unequivocally defined, the tumor was extending extrameatally. One patient had a purely intrameatal acoustic neur…

Non-chemotherapy drug-induced agranulocytosis in a tertiary hospital

2015

Drug-induced agranulocytosis is a rare haematological disorder considered as severe adverse drug reaction. Due to its low incidence, the number of studies are low and the variability of clinical features and presentation in hospitalized patients is rarely described. Awe performed an observational, transversal and retrospective study in the haematology and toxicology unit in a tertiary hospital located in Spain (Valencia) (1996–2010) in order to assess its incidence, the drugs involved, the management and outcomes of drug-induced agranulocytosis. Twenty-one cases of agranulocytosis were retrieved. All of them presented severe and symptomatic agranulocytosis (fever and infection). The most c…

Assessing audiological, pathophysiological and psychological variables in tinnitus patients with or without hearing loss

2010

The aim of this work is to study the characteristics of tinnitus both in normal hearing subjects and in patients with hearing loss. The study considered tinnitus sufferers, ranging from 21 to 83 years of age, who were referred to the Audiology Section of Palermo University in the years 2006–2008. The following parameters were considered: age, sex, hearing threshold, tinnitus laterality, tinnitus duration, tinnitus measurements and subjective disturbance caused by tinnitus. The sample was divided into Group1 (G1), 115 subjects with normal hearing, and Group2 (G2), 197 subjects with hearing loss. Especially for G2, there was a predominance of males compared to females (P = 0.011); the highest…

DPOAE‐Grams in Patients with Acute Tonal Tinnitus

2005

To investigate cochlear outer hair cell function in patients with acute tonal tinnitus and normal or near-normal hearing threshold.Prospective controlled study in an academic tertiary health center. Distortion products of otoacoustic emissions (DPOAE)-grams of 32 ears with acute tonal tinnitus and normal hearing or minimal hearing loss were compared with those of 17 healthy nontinnitus ears.Tinnitus ears exhibited relatively increased amplitudes of DPOAE at high frequencies (4-6.3 kHz) when compared with the group of healthy ears and relatively decreased DPOAE amplitudes at middle frequencies (1650-2400 Hz). Statistically significant ( P0.01) increased mean values of DPOAE amplitudes were o…

Sudden Sensorineural Hearing Loss: Results of intratympanic steroids as salvage treatment

2012

Objective: The aim of the present study was to verify the efficacy and the safety of intratympanic dexamethasone to treat sudden sensorineural hearing loss as salvage therapy. Materials and methods: A prospective study was conducted on patients affected by idiopathic sudden hearing loss who were treated before with some systemic therapy, but without recovery of the hearing The patients able to undergo the study, but who refused salvage treatment were considered as control group. A solution of Dexamethasone 4 mg/ml was then injected through the posterior–inferior quadrant filling completely the middle ear. The follow-up in the following 6 months included an audiogram every month. Results: Th…

Risk of infection and adverse outcomes among pregnant working women in selected occupational groups: A study in the Danish National Birth Cohort

2010

Abstract Background Exposure to infectious pathogens is a frequent occupational hazard for women who work with patients, children, animals or animal products. The purpose of the present study is to investigate if women working in occupations where exposure to infections agents is common have a high risk of infections and adverse pregnancy outcomes. Methods We used data from the Danish National Birth Cohort, a population-based cohort study and studied the risk of Infection and adverse outcomes in pregnant women working with patients, with children, with food products or with animals. The regression analysis were adjusted for the following covariates: maternal age, parity, history of miscarri…

Learning Curve and Fatigue Effect of Flicker Defined Form Perimetry

2011

To evaluate the learning curve and fatigue effect of flicker defined form (FDF) perimetry.Prospective cross-sectional study.One hundred forty-one eyes of 75 healthy subjects were included in the study. Every subject was measured 3 times on 3 different days within 3 months. Differences among the tests were analyzed for mean sensitivity (MS), mean deviation (MD), pattern standard deviation (PSD), reliability indices, test duration, and test points5% and0.5% in 75 right eyes on the basis of linear mixed models for repeated measurements. To assess the effect of fatigue, differences of MS, MD, and PSD values between 66 left and right eyes were evaluated regarding alterations between these 3 exam…

Is There Really Increased Cardiovascular Morbidity in Women with Polycystic Ovary Syndrome?

2018

For some time, it has been assumed that women with polycystic ovary syndrome (PCOS) are at increased risk of developing cardiovascular disease (CVD). This has largely been on the basis of having many risk factors, including abnormal lipid profile, insulin resistance, and markers of inflammation. However, despite having these and other risk factors, we argue here, in the view of the authors, that there is no credible evidence that there is greater CVD morbidity in all women with PCOS. We analyze the existing data and discuss that overall CVD risk decreases with age when more CVD events are likely to occur, and introduce the possibility that there may be some unknown inherent protective facto…

Low-molecular-weight heparin to prevent recurrent venous thromboembolism in pregnancy: Rationale and design of the Highlow study, a randomised trial …

2016

Summary Background Women with a history of venous thromboembolism (VTE) have a 2% to 10% absolute risk of VTE recurrence during subsequent pregnancies. Therefore, current guidelines recommend that all pregnant women with a history of VTE receive pharmacologic thromboprophylaxis. The optimal dose of low-molecular-weight heparin (LMWH) for thromboprophylaxis is unknown. In the Highlow study (NCT 01828697; www.highlowstudy.org ), we compare a fixed low dose of LMWH with an intermediate dose of LMWH for the prevention of pregnancy-associated recurrent VTE. We present the rationale and design features of this study. Methods The Highlow study is an investigator-initiated, multicentre, internation…
