THE LINKAGE BETWEEN UPPER RESPIRATORY TRACT INFECTIONS AND OTITIS MEDIA: EVIDENCE OF THE 'UNITED AIRWAYS CONCEPT'

Upper respiratory tract infection (URTI) is a nonspecific term used to describe acute infections involving the nose, paranasal sinuses, pharynx and larynx and resulting from interplay between microbial load (viral and bacterial) and immune response. Infant and young children are prone to developing upper respiratory tract infections, which often result in bacterial complications especially acute otitis media because of the passage of bacteria (colonizing the nasopharynx) in the middle ear via Eustachian tube.

Burden of Disease in PWH Harboring a Multidrug-Resistant Virus: Data from the PRESTIGIO Registry

AbstractBackgroundCurrently, no data are available on the burden of morbidity and mortality in people with HIV-1 (PWH) harboring a 4-class drug-resistant (4DR) virus (nucleoside reverse transcriptase inhibitors, non-nucleoside reverse transcriptase inhibitors, protease inhibitors, integrase strand transfer inhibitors). The study aimed to assess the incidence of clinical events and death in this population.MethodsThis was a cohort study on PWH from the PRESTIGIO Registry with a documented 4DR virus. Burden of disease was defined as the occurrence of any new event including an AIDS-defining event (ADE) or non-AIDS-defining event (NADE) or death from any cause after 4DR evidence (baseline). Co…

Management of infants with neural tube defects (NTDs) in NICU

Neural tube defects (NTDs) are a group of congenital malformations of the central nervous system, which derive from an altered embryological development during neurulation. The different types of NTDs are closely related to their onset in the embryonic period; precocity is an index of greater severity of clinical manifestation. The myelomeningocele is one of the most common pathological conditions which is included into the spectrum of NTDs. It is characterized by the lack of fusion of the vertebral arches, resulting in eversion of the meninges and medullary content; it is the condition which clearly needs more assistance in the neonatal intensive care unit. The management of patients with …

FOLLOW-UP AFTER PEDIATRIC MYRINGOPLASTY: OUTCOME AT 5 YEARS

Anatomia e patologia del labirinto membranoso studio con sequenze RM sensibili al flusso

Nonostante i deludenti esordi nella valutazione delle strutture labirintiche costituenti l'orecchio interno, la risonanza magnetica costituisce oggi, grazie anche al miglioramento dell'hardware e del software disponibili, una modalità diagnostica di grande efficacia non solo nell'analisi della patologia espansiva o infiammatoria coinvolgente il VII ed VIII nervo cranico, ma anche nella valutazione delle alterazioni patologiche del segnale endolabirintico in rapporto a focolai emorragici o, come recentemente dimostrato mediante uso di Gd-DTPA, nell'analisi delle alterazioni a carico della capsula oticanella fase spongiotica dell'otosclerosi. Tuttavia, lo scarso contrasto esistente tra liqui…

Hearing loss in neonatal intensive care units (NICUS): Follow-up surveillance

Infants admitted to the neonatal intensive care unit (NICU), who represent the 4-8% of all births, present problems such as prematurity, low Apgar scores, infections, hyperbilirubinemia and hearing impairment. In particular significant hearing loss is the most common disorder at birth, occurring in 1 to 2 newborns per 1000 in the general population and 24% to 46% of newborns who are admitted to a NICU. This leads more difficulty to develope verbal skills (learning vocabulary, grammar, word order and idiomatic expressions), language, learning and speech. Hearing impairment influences also cognitive and affective development of infants making consequences in their interpersonal relationships.…

Extramedullary plasmacytoma of the tonsil: A new management

Introduction: Extramedullary plasmacytoma (EMP) is a rare tumor of all plasma cell neoplasms. The tumor is mainly localized in the head and neck region, but rarely involving the tonsil. Case presentation: The authors report the 5th case of EMP of the tonsil in the literature occurred in a 57-year-old Caucasian male. Conclusions: Through a review of the relevant literature, we consider adjuvant radiotherapy not necessary for EMP of tonsil because of an adequate resection achieved by surgery.

The Role of Magnetic Resonance Imaging in Central Hearing Deficits: Beyond the Acoustic Schwannoma

Acoustic schwannoma is assumed to be the most common cause of sensory-neural hearing loss (SNHL), and many papers have described the role of magnetic resonance imaging (MRI) in the diagnosis of cerebello-pontine angle (CPA) tumours, particularly schwannoma. We retrospectively examined 72 patients complaining of different clinical syndromes and SNHL or different kinds of acoustic impairment who underwent MRI brain study excluding the presence of acoustic schwannoma and other CPA masses. In conclusion, although acoustic schwannoma is the most common cause of acquired HD, a lesion involving the neural centers of the acoustic pathway can also determine SNHL or HD. Considering the high sensitiv…

Frontal sinus osteoma and palpebral abscess: Case report

Osteomas of the paranasal sinuses are slow-growing, benign tumours most frequently found in the frontal sinus with an incidence that varies from 47% to 80% of the cases; there are often no symptoms and they are diagnosed by chance during an x-ray examination. The symptoms are usually headaches and those secondary to ocular or neurological complications. The therapy to be preferred is surgery. The authors describe a case of frontal osteoma complicated by frontal sinusitis and palpebral abscess.

AGE-RELATED HEARING IMPAIRMENT (ARHI): A COMMON SENSORY DEFICIT IN THE ELDERLY

This paper aims to give a broad overview of the scientific findings related to Age-related hearing impairment that is a complex disorder, with both environmental as well as genetic factors contributing to the impairment. The involvement of several environmental factors has been partially elucidated. A first step towards the identification of the genetic factors has been made, which will result in the identification of susceptibility genes, and will provide possible targets for the future treatment and/or prevention of ARHI.

Association between sleep-disordered breathing and hearing disorders: Clinical observation in Sicilian patients

Introduction: To examine the putative association between Sleep-Disordered breathing and hearing disorders Material and methods: 120 Sicilian subjects ranging from 14 to 85 years of age who were divided in 46 cases suffering from tinnitus (G1 group) and 74 controls (G2 group) were evaluated through STOP BANG screening questionnaire and Four-Variable Screening Tool; after Data collecting each subject underwent Audiological assessment by multi-frequency audiometry (PTA) and Transient-evoked otoacoustic emissions (TEOAE-diagnostic) for each ear.

Newborn hearing screening in Sicily: Lesson learned

The motor development of preterm infants after the neonatal intensive care unit

The extra uterine environment is a hostile environment, due to noises, lights and different biological activities compared to intra uterine environment for infants born preterm or underweight. Stress and painful experiences may also impact developmental outcomes. In addition, developmental delay risks increase with the decrease in gestational age. Thus, those born with immature developed systems may need neonatal intensive care units (NICU) in order to allow a correct growth and body maturation. In general, infants that need NICUs suffer from a slower development compared to their full-term peers. This may translate in a delay in oral, tactile, kinesthetic, vestibular, auditory, olfactory, …

TINNITUS PATIENTS: ETIOLOGIC, AUDIOLOGIC AND PSYCHOLOGICAL PROFILE

ANF IN THE PAROTID GLAND IN RABBIT.

It is well known that the presence of a particular type of granule population has been discovered in the atrial cardiocytes which represent the major site of synthesis of atrial natriuretic factor. The ANF has potent natriuretic, diuretic and vasoactive functions. However, ANF evidence occurs in extracardiac tissues such as the brain, intestine, lymphoid organs and in various glands involved in water and salt regulation adrenals, pancreas, lacrimal and salivar glands with respect to salivary glands the literature reportes that ANF presence was found in the acinar cells and on the contrary in the ductal cells. In order to eliminatethese discordances researchers conducted a previous study on …

Upper respiratory tract infections in children: From case history to management

Respiratory tract infections are the most common diseases in childhood. The respiratory tract, widely branched system of ducts, is particularly exposed to the action of microorganisms transmitted by air from here the high frequency of infections they face especially in the first years of life. It is usual distinguish: upper respiratory tract infections (URTI) and lower respiratory tract infections (LRTI). In particular, in infections of the upper airways, the inflammatory process, result of the interaction between microbes and the immune response, can be localized to the mucosa of the nose or sinuses (common cold and sinusitis), or the pharynx or larynx (pharyngotonsillitis and laryngitis) …

MRI of the inner ear: use of modified GRASS and fast spin-echo sequences

We report our experience with MRI of the normal and pathological inner ear with fast spin-echo and modified gradient recalled at steady state sequences. Although earlier studies on temporal bone MRI were discouraging, improvements in MR technology combined with the use of paramagnetic contrast media can make MRI a useful diagnostic tool for the assessment of inner ear pathology. Conventional spin-echo imaging seems not to be the modality of choice because of the relatively thick slices and the long acquisition times.

Considerations on super Poincare algebras and their extensions to simple superalgebras

We consider simple superalgebras which are a supersymmetric extension of $\fspin(s,t)$ in the cases where the number of odd generators does not exceed 64. All of them contain a super Poincar\'e algebra as a contraction and another as a subalgebra. Because of the contraction property, some of these algebras can be interpreted as de Sitter or anti de Sitter superalgebras. However, the number of odd generators present in the contraction is not always minimal due to the different splitting properties of the spinor representations under a subalgebra. We consider the general case, with arbitrary dimension and signature, and examine in detail particular examples with physical implications in dimen…
