Clinical features of the impact of eating disorders on the results of 13C-methacetin breath test for assessment of liver function in girls with anore…

2019

Introduction: This study was designed to assess the influence of chosen aspects of anorexia nervosa eating disorders (AN ED) on 13C-methacetin breath test (MBT) results. Material and methods: We investigated a group of 81 girls, including 41 patients with confirmed diagnosis of AN ED. The study group was divided in two subgroups. According to the DSM-5 classification, 25 underweight patients met the criteria of anorexia nervosa (AN), and 16 girls with BMI value > 5th percentile for age and sex were diagnosed as atypical anorexia nervosa (AAN). Laboratory tests assessing the liver function and the MBT were performed in all the participants of the study. Results: In all healthy females the va…

Effect of gastric acid suppression on 13 C-urea breath test: comparison of ranitidine with omeprazole

2000

Background: The assessment of the effect of H2 antagonists on the results of the urea breath test has produced controversial results. Aim: To assess whether standard doses of both omeprazole and H2 blockers can adversely influence the accuracy of the urea breath test. Methods: Sixty dyspeptic patients with ascertained Helicobacter pylori infection were recruited for this prospective, open study. They were randomized to receive either omeprazole 20 mg at 08:00 hours (n = 30) or ranitidine 300 mg at 22:00 hours (n = 30) for 14 days. The urea breath test was performed at baseline, on day 14, while patients were still taking the antisecretory drugs, and on day 21, 1 week after their cessation. …

Stool antigen assay (HpSA) is less reliable than urea breath test for post-treatment diagnosis of Helicobacter pylori infection

2002

Summary Background : The diagnostic yield of the stool antigen test (HpSA) in evaluating the results of Helicobacter pylori eradication therapy is controversial, but many studies have used only the 13C-urea breath test (13C-UBT) as a gold standard which has greatly reduced their relevance. Aim : To compare the reliability of HpSA and 13C-UBT in patients post-treatment using biopsy-based methods as reference tests. Methods : A total of 100 consecutive dyspeptic patients (42 male and 58 female; mean age, 56 ± 18 years) were enrolled in our study. All patients were H. pylori positive on the basis of at least two biopsy-based methods, and underwent 1 week of treatment with various triple therap…

Diagnostic Accuracy of <sup>13</sup>C-Urea Breath Test in the Diagnosis of <i>Helicobacter pylori</i> Infection in Patients w…

2001

<i>Aims:</i> We investigated the diagnostic properties of the <sup>13</sup>C-urea breath test (<sup>13</sup>C-UBT) prospectively. These are well validated in nonresected patients before and after treatment of <i>Helicobacter pylori</i> infection but not in patients with partial gastric resection due to peptic ulcer disease. <i>Methods:</i> Hospitalized patients with previous gastric resection and indications for upper gastrointestinal endoscopy were recruited for the study. Biopsy specimens were obtained from the fundus mucosa and the gastric remnant adjacent to the gastroenteric anastomosis for histological examination and rapid u…

Automatic bilevel ventilation in sleep-disordered breathing: A real-life experience in southern Italy

2016

Automatic bilevel ventilation (AutoBI) has been recently introduced to treat obstructive sleep-disordered breathing (SDB), but clinical experience is still limited. We revised the charts of patients treated for obstructive SDB in our sleep clinic in 2015 (n=214) to assess the frequency of trials of AutoBI ventilators (ResMed Auto25 or Respironics BiFlex), the clinical characteristics of these patients, the reason to shift from CPAP to AutoBI, and the outcome of AutoBI titration. A trial of domiciliary AutoBI was made in 44 patients (20.5%) intolerant to CPAP due to high CPAP levels (n=11) or who showed incomplete resolution of SDB on CPAP (n=33). The table reports the clinical data accordin…

Episodic Breathlessness with and without Background Dyspnea in Advanced Cancer Patients Admitted to an Acute Supportive Care Unit

2020

Aim: To characterize episodic breathlessness (EB) in patients with advanced cancer, and to determine factors influencing its clinical appearance. Methods: A consecutive sample of advanced cancer patients admitted to an acute palliative care unit was surveyed. Continuous dyspnea and EB were measured by a numerical scale. The use of drugs used for continuous dyspnea and EB was recorded. Patients were asked about the characteristics of EB (frequency, intensity, duration and triggers). The Multidimensional dyspnea profile (MDP), the Brief dyspnea inventory (BDI), the Athens sleep scale (AIS) and the Hospital Anxiety and Depression Scale (HADS) were also administered. Results: From 439 advanced …

Sleep disordered breathing in medically stable patients with myasthenia gravis

2007

We investigate sleep and breathing in clinically stable myasthenia gravis (MG) patients and ask weather sleep disordered breathing (SDB) is causally linked with MG. Nineteen MG patients with a mean disease duration of 9.7 years underwent sleep studies in two consecutive nights. The primary outcome measure was the respiratory disturbance index (RDI) in terms of snoring and apneas/hypopneas. Further outcome measurements were total sleep time, sleep stage distribution and the number of arousals. A clinically relevant SDB in terms of obstructive sleep apnea (OSA) (defined as RDI > 10/h) was found in four patients. There were only a few central apneas (central apnea index: 0.19 +/- 0.4/h). We di…

Effects of adenotonsillectomy on neurocognitive and behavioural function in pediatric obstructive sleep apnea syndrome

2018

Effects of adenotonsillectomy on neurocognitive and behavioural function in pediatric obstructive sleep apnea syndrome. Objectives: Aim of this study is to verify the presence of neurocognitive, neurobehavioral or sleep disturbances in children affected by adenotonsillar hypertrophy (ATH) and Obstructive Sleep Apnea Syndrome (OSAS) and verify their improvement after Adeno-Tonsillectomy (AT). Methods: Eighty children suffering from adenotonsillar hypertrophy and OSAS were recruited for AT in the ENT Department of the University of Palermo. All the children underwent clinical evaluation, including rhinofibroscopy for grading the obstruction due to the adenotonsillar hypertrophy (before and 6 …
