Mortality in patients with coeliac disease and their relatives: a cohort study.
2001
Summary Background Although previous studies have shown increased mortality in patients with coeliac disease and their relatives, no data are available in relation to different patterns of clinical presentation. We assessed mortality in patients with coeliac disease and their first-degree relatives. Methods We enrolled, in a prospective cohort study, 1072 adult patients with coeliac disease consecutively diagnosed in 11 gastroenterology units between 1962 and 1994, and their 3384 first-degree relatives. We compared the number of deaths up to 1998 with expected deaths and expressed the comparison as standardised mortality ratio (SMR) and relative survival ratio. Findings 53 coeliac patients …
Endovascular treatment of CCSVI in patients with multiple sclerosis: clinical outcome of 462 cases
2013
Although it is still debated whether chronic cerebro-spinal venous insufficiency (CCSVI) plays a role in multiple sclerosis (MS) development, many patients underwent endovascular treatment (ET) of CCSVI. The objective of the study is to evaluate the outcome and safety of ET in Italian MS patients. Italian MS centers that are part of the Italian MS Study Group were all invited to participate to this retrospective study. A structured questionnaire was used to collect detailed clinical data before and after the ET. Data from 462 patients were collected in 33 centers. ET consisted of balloon dilatation (93 % of cases) or stent application. The mean follow-up duration after ET was 31 weeks. Mean…
Juvenile Xanthogranuloma and Nevus Anemicus in the Diagnosis of Neurofibromatosis Type 1
2013
Importance The diagnosis of neurofibromatosis type 1 (NF1) is based on 7 clinical criteria. However, they are of limited value before the age of 2 years. Juvenile xanthogranuloma (JXG) and nevus anemicus (NA) are commonly observed in children with NF1 and may be useful diagnostic clues. Objectives To evaluate the frequency of JXG and NA, to describe their clinical features, and to determine their diagnostic value in patients with NF1. Design, Setting, and Participants Retrospective medical record review of outpatients seen between January 1, 2005, and December 31, 2011. University hospital dermatology department affiliated with the French NF1 referral center network. Patients with NF1 diagn…
Pattern of symptoms and symptomatic treatment in adults and the aged population: a retrospective analysis of advanced cancer patients followed at hom…
2016
Context Data regarding symptom burden and symptomatic drugs in palliative population in different classes of age are lacking. Objective The aim of this retrospective study was to assess the symptom burden, and the profile of symptomatic drugs in the last four weeks of life in adults and older cancer patients followed at home. Methods Charts of 412 patients were retrospectively analyzed by using a backward analysis. Patients were divided into three groups: adults (<65 years, A), old (65-74 years, O1), very old (75-84 years, O2), and the oldest (≥85 years, O3). Results At -4W Karnofsky status was significantly lower for older people (p = 0.03). No significant effect of age on the vector of sy…
Efficacy of Therapeutic Intervention in Headache Units in Patients With Frequent Headaches: The EFUNCE Study
2006
Data confirming that therapeutic intervention in headache units is superior to care received by patients in other levels of the health system are scant. This is a pilot study that includes patients seen in 4 headache units for at least 1 year, who had a headache frequency of more than 15 days per month. The results of the first 30 patients showed a significant improvement in different headache parameters and a high degree of satisfaction with the treatment received.
PREGO (presentation of Graves' orbitopathy) study: changes in referral patterns to European Group On Graves' Orbitopathy (EUGOGO) centres over the pe…
2015
BACKGROUND/AIMS: The epidemiology of Graves' orbitopathy (GO) may be changing. The aim of the study was to identify trends in presentation of GO to tertiary centres and initial management over time.METHODS: Prospective observational study of European Group On Graves' Orbitopathy (EUGOGO) centres. All new referrals with a diagnosis of GO over a 4-month period in 2012 were included. Clinical and demographic characteristics, referral timelines and initial decisions about management were recorded. The data were compared with a similar EUGOGO survey performed in 2000.RESULTS: The demographic characteristics of 269 patients studied in 2012 were similar to those collected in the year 2000, includi…
Reproductive outcome of women with 21-hydroxylase-deficient nonclassic adrenal hyperplasia.
2006
Many women with 21-hydroxylase (21-OH)-deficient nonclassic adrenal hyperplasia (NCAH) carry at least one allele containing a severe mutation of CYP21, and as such are at risk for giving birth to an infant having classic adrenal hyperplasia (CAH). Infants with NCAH typically are asymptomatic at birth, in contrast to those with CAH, but they do develop symptoms of hyperandrogenism later in childhood or as adults. This international multicenter study, conducted both retrospectively and prospectively, was an attempt to determine how often mothers with 21-OH-deficient NCAH bear infants having CAH or NCAH. The 101 women entering the study had a total of 203 pregnancies that could be evaluated. F…
Latvian registry of familial hypercholesterolemia: The first report of three-year results.
2018
Abstract Background and aims Familial hypercholesterolemia (FH) was rarely diagnosed in Latvia before 2015, when the Latvian Registry of FH (LRFH) was established. Here, we report the first experience of the LRFH over three years (2015–2017). Methods The LRFH is an ongoing nationwide, dynamic, long-term prospective cohort. The diagnosis of FH was assessed using the Dutch Lipid Clinic Network (DLCN) criteria. Cascade screening of first-degree relatives using age- and sex-specific percentiles of low-density lipoprotein cholesterol (LDL-C) was performed in relatives of patients with definite and probable FH. Results Among the 416 individuals included in the LRFH, 181 patients were diagnosed wi…
Incidence and risk factors in sudden unexpected death in epilepsy: a prospective cohort study.
2001
Objective: To determine incidence of and risk factors for sudden unexpected death in epilepsy (SUDEP). Methods: Three epilepsy centers enrolled 4,578 patients and prospectively followed these patients for 16,463 patient-years. The cohort was screened for death annually. Deaths were investigated to determine whether SUDEP occurred. Potential risk factors were compared in SUDEP cases and in controls enrolled contemporaneously at the same center. Results: Incidence of SUDEP was 1.21/1,000 patient-years and was higher among women (1.45/1,000) than men (0.98/1,000). SUDEP accounted for 18% of all deaths. Occurrence of tonic-clonic seizures, treatment with more than two anticonvulsant medications…
