OBJECTIVE To assess short- and long-term effects of rapid maxillary expansion (RME) on nasal flow in young children. Since RME has been reported to positively influence nasal obstruction in subjects with respiratory problems by reducing nasal resistance, a similar efficacy of RME could be expected in children with deciduous and/or mixed dentition who are(More)
OBJECTIVE To determine whether antisperm antibodies can interfere with the induction of the acrosome reaction (AR) by the zona pellucida (ZP) and whether this interference also can occur in the absence of an inhibitory effect on ZP binding. DESIGN Prospective in vitro study. SETTING A tertiary care center, the Andrologic Clinic, University of L'Aquila.(More)
PROBLEM This study was performed to evaluate the occurrence as well as the level of the interference of sperm-associated antibodies on fertilization process. METHOD Motile sperm suspensions from 28 infertile patients with high degree of autoimmunization against the sperm head were tested with the zona pellucida (ZP) binding test and with the sperm(More)
OBJECTIVE To determine if a low acrosin activity in otherwise normal ejaculate from infertile patients is associated with an impairment of sperm functions involved in the hamster egg penetration. SETTING A tertiary care center, the Andrology Clinic, Department of Internal Medicine, University of L'Aquila. PATIENTS Nine infertile patients with low(More)
Paget's disease (PD) is a common focal progressive osteometabolic disorder characterised by a disturbance in bone modelling and remodelling, because of an increase in osteoblastic and osteoclastic activity. It is a condition of unknown aetiology affecting approximately 3% of the population over 40 years of age and, approximately 10% of those over the age of(More)
OBJECTIVE To determine if the overcoming of the cervical mucus barrier removes the interference of sperm-bound antibodies with fertility. DESIGN Prospective case series. SETTINGS University-based intrauterine insemination (IUI) homologous program. PATIENTS Nineteen patients with all spermatozoa in the ejaculate coated by antisperm antibodies. As(More)
OBJECTIVE To determine the relationship between acrosome reactions and hamster egg penetration after ionophore challenge in nonteratozoospermic semen samples. SETTING A tertiary care center, the Andrologic Clinic, Department of Internal Medicine, University of L'Aquila. PATIENTS Twenty-five nonteratozoospermic patients with infertile marriages and nine(More)
OBJECTIVE To identify eventual correlations between the effect of low-pressure treatment and endolymphatic hydrops in Ménière patients. MATERIAL AND METHODS The study group consisted of subjects affected by definite Ménière disease (2015) and a severe degree of disability, who received a ventilation tube with or without a low-pressure treatment before(More)
CONCLUSIONS The RetroX outer ear hearing aid seems to represent a means of overcoming problems with understanding speech in noise in patients with high-frequency sensorineural hearing loss (SNHL) without the need to wear conventional completely-in-the-canal (CIC) hearing aids, which are usually reported to annoy patients as a result of the occlusion effect.(More)
