The impact of neonatologist performed echocardiography in an Italian neonatal unit.

BACKGROUND: The main goal of neonatologist performed echocardiography is to timely assess hemodynamic changes in order to properly manage unsteady neonates. Detailed structural heart assessment remains the domain of pediatric cardiologists. Nonetheless, many neonatologists take on an additional role in diagnosis of congenital heart defects, mostly compelled by the lack of in-house pediatric cardiology services. The experience of neonatologist performed echocardiography in an Italian neonatal unit was reported and the risk benefit profile of this practice was discussed. MATERIAL AND METHODS: We retrospectively reviewed the echocardiograms undertaken by the neonatologist on infants admitted to the neonatal unit and postnatal ward of the Hospital San Pio in Benevento, over a 2-year period. Details of scans and concordance between neonatologist and cardiologist were analyzed. RESULTS: A total of 160 echocardiographic studies were done by the neonatologist on 136 infants. The ECG was requested in a minority of infants. The most common reason for performing the echocardiogram was admission to the neonatal care unit. Around half of the echocardiograms were normal. The remaining scans resulted in functional and structural abnormalities, transitional changes, and doubtful findings. Cardiac anomalies were significantly more likely found in cases of echocardiograms performed for fetal indications. Only 28 patients were eventually referred to the cardiology services. The inter-rater agreement was satisfactory. CONCLUSIONS: The hemodynamic assessment of sick infants, as well as triaging and referral of neonates with structural heart diseases are valuable advantages of the echocardiography run by neonatologists.Collaboration with pediatric cardiologists and robust training and accreditation programs are essential to ensure safety and quality service.

Report from a Consensus Conference on the treatment of Ménière's disease with betahistine: rationale, methodology and results.

Ménière's disease is a disorder of the inner ear that causes vertigo, tinnitus, fullness and hearing loss. Although several treatments are available, the success rate is reported to be around 70%, similar to placebo. Betahistine, a weak H1 receptor agonist and an effective H3 receptor antagonist, is frequently prescribed for Ménière's disease, especially to reduce recurrent vertigo attacks. The effects of this drug on hearing and other audiological symptoms remains unclear. Given the inconclusive reports in the literature, we proposed a consensus conference on the use of betahistine in Ménière's disease. The aim was to define best practice criteria for therapy for Ménière's disease, improve clinical suitability and reduce heterogeneity of the therapeutic approach. The consensus conference on betahistine for Ménière's disease involved a group of Italian experts in vestibular disorders who were asked a series of questions prepared by opinion leaders. The Delphi method, an iterative investigation method, was used to increase consensus. Via a tele-voting system, each participant anonymously evaluated all statements using a Likert 5-point scale. Betahistine was considered useful for the treatment of dizziness and vertigo during the intercritical phase of the disease (87% agreeing answers). However, during the acute phase of the disease betahistine was considered less effective and useful only when associated with other drugs (71% agreement). Similarly, the efficacy of the drug was considered low when used to reduce progressive hearing loss, tinnitus, and ear fullness. The experts advocated the use of betahistine during the intercritical phase of Ménière's disease to reduce the number and severity of vertigo attacks. Its use seems to be at low risk of major side effects.

Oxidative Stress in Cerebral Small Vessel Disease Dizziness Patients, Basally and After Polyphenol Compound Supplementation.

BACKGROUND: Leukoaraiosis (LA) is a common radiological finding in elderly, frequently associated with several clinical disorders, including unexplained dizziness. The pathogenesis of LA is multifactorial, with a dysfunction of cerebral microcirculation resulting in chronic hypoperfusion and tissue loss, with oxidative stress involved in this cascade. OBJECTIVE: The aim of this study was to analyse some oxidative stress biomarkers in a cohort of LA patients. METHOD: Fifty-five consecutive patients (33 males, median age 75 years) with LA were recruited. In a subgroup of 33 patients with LA and unexplained dizziness, we have then performed an open study to evaluate if 60-day supplementation with a polyphenol compound may modify these biomarkers and influence quality of life, analysed with the Dizziness Handicap Inventory (DHI) scale. RESULTS: At baseline, blood oxidative stress parameters values were outside normal ranges and compared to matched healthy controls. After the two months supplementation, we observed a significant decrement of advanced oxidation protein products values and a significant improvement of DHI. CONCLUSION: Oxidative stress biomarkers may be useful to detect redox imbalance in LA and to provide non-invasive tools to monitor disease status and response to therapy.

Paroxysmal positional vertigo despite complete vestibular impairment: the role of instrumental assessment.

Lindsay-Hemenway syndrome is characterised by a posterior canal benign paroxysmal positional vertigo following a partial unilateral vestibular loss affecting the same side. The syndrome is caused by damage of structures innervated by the superior division of the vestibular nerve and perfused by the anterior vestibular artery; the detached otoconia can cause vertigo in the still intact posterior semicircular canal. The most recent vestibular instrumental techniques allow reaching an accurate topodiagnosis in case of peripheral vestibular failure. We report on two cases of Lindsay-Hemenway syndrome despite complete vestibular failure demonstrated by vestibular instrumental assessment. After making some critical considerations on these findings, we underline the importance of not disregarding the diagnosis of paroxysmal positional vertigo in an established complete labyrinthine loss of function.

Prevalence, molecular characterization, and clinical relevance of sensitization to Anisakis simplex in children with sensitization and/or allergy to Dermatophagoides pteronyssinus.

SUMMARY: Prevalence of the Anisakis Simplex's (AS) sensitization in children sensitized to Dermatophagoides pteronissynus (DP) is not known, neither it is to which percentage it might be due to cross-reactivity. The primary objective of the present retrospective cross-sectional study is to evaluate the prevalence of sensitization to AS in children sensitized or allergic to DP. Secondary outcomes were the prevalence of cross-reactivity and clinical relevance of the condition. The prevalence of sensitization to AS differs significantly among patients sensitized and not to DP (13.43% vs. 3.80%; p=0.019). The higher prevalence is mainly due to cross-reactivity with Der p10 (OR=8.86; 95% CI=4.33-40.74; p=0.0001). Currently, the sensitization to AS seems to have no clinical relevance in the pediatric population.

Italian survey on benign paroxysmal positional vertigo.

Benign paroxysmal positional vertigo (BPPV) is the most common type of peripheral vertigo. BPPV often relapses after the first episode, with a recurrence rate between 15% and 50%. To date both the aetiopathogenetic processes that lead to otoconia detachment and the factors that make BPPV a relapsing disease are still unclear, but recent epidemiological studies have shown a possible association with cardiovascular risk factors. The aim of the present study (Sesto Senso Survey) was to evaluate in the Italian population through an observational survey, the main demographic and clinical characteristics of patients with BPPV (first episode or recurrent) with particular focus on the potential cardiovascular risk factors. The survey was conducted in 158 vestibology centres across Italy on 2,682 patients (mean age 59.3 ± 15.0 years; 39.1% males and 60.9% females) suffering from BPPV, from January 2013 to December 2014. The results showed a high prevalence of cardiovascular risk factors such as high blood pressure (55.8%), hypercholesterolaemia (38.6%) and diabetes (17.7%), as well as a family history of cardiovascular disease (49.4%). A high percentage of patients also had hearing loss (42.9%), tinnitus (41.2%), or both (26.8%). The presence of hypertension, dyslipidaemia and pre-existing cardiovascular comorbidities were significantly related to recurrent BPPV episodes (OR range between 1.84 and 2.31). In addition, the association with diabetes and thyroid/autoimmune disease (OR range between 1.73 and 1.89) was relevant. The survey results confirm the significant association between cardiovascular comorbidities and recurrent BPPV and identify them as a potential important risk factor for recurrence of BPPV in the Italian population, paving the way for the evaluation of new therapeutic strategies in the treatment of this disease.

Surgical complications in orbital decompression for Graves' orbitopathy.

The objective of this study is to analyse the complications of orbital decompression in Graves' orbitopathy. The clinical records of 946 patients who had been operated on with orbital decompression for Graves' orbitopathy were reviewed and the intra- and post-operative complications with minimum follow-up of six months were analysed. An extensive review of the literature was carried out to compare results. In the case-series reported here the most frequent complications were: wasting of the temporal region (100%) in patients operated on using a coronal approach; permanent hypoesthesia of V2 (13%) and V1 (8%) in patients operated on with an upper eyelid incision. In only one patient was a total monolateral lesion of V2 reported. The most severe complications consisted in reduction of visual acuity in 5 patients, and CSF leak with cerebral complications in 2 patients, who were operated on with a non-endoscopic endonasal approach. Three patients had intra-operative haemorrhages and 3 patients had post-operative haemorrhages requiring further surgical intervention. The incidence of symptomatic sinusitis/mucoceles was 0.75%. In conclusion, orbital decompression carried out with endoscopic endonasal technique and via transpalpebral accesses appears to be associated with a low incidence of complications. Knowledge of the causes of the possible complications in the different surgical approaches can definitely help to reduce their incidence.

Isolated laryngeal leishmaniasis in an immunocompetent patient: a case report.

Isolated laryngeal leishmaniasis in an immunocompetent patient: a case report. OBJECTIVE: Isolated laryngeal Leishmaniasis presents neither explicit laryngeal lesions nor specific symptoms. In fact, it may mimic many inflammatory and neoplastic diseases. Considering the low incidence of this atypical localization, laryngeal Leishmaniasis, is rarely contemplated by physicians in differential diagnoses of laryngeal tumour lesions. We present the case of a 62-year-old immunocompetent subject who developed a single Leishmania mucosal lesion on the left vocal cord, simulating a laryngeal cancer. METHODS: A case report and discussion of the clinical case by referring to the literature. RESULTS: Specific therapy with miltefosine led to clinical and endoscopic improvement. We had no relapse after three years of follow-up. CONCLUSIONS: This clinical case highlights the need to consider isolated laryngeal Leishmaniasis in the differential diagnoses of laryngeal tumour lesions, even in immunocompetent subjects who live in endemic zones, in order to ensure an early and correct therapeutic approach.

Vertigo in childhood: proposal for a diagnostic algorithm based upon clinical experience.

The aim of this paper is to analyse, after clinical experience with a series of patients with established diagnoses and review of the literature, all relevant anamnestic features in order to build a simple diagnostic algorithm for vertigo in childhood. This study is a retrospective chart review. A series of 37 children underwent complete clinical and instrumental vestibular examination. Only neurological disorders or genetic diseases represented exclusion criteria. All diagnoses were reviewed after applying the most recent diagnostic guidelines. In our experience, the most common aetiology for dizziness is vestibular migraine (38%), followed by acute labyrinthitis/neuritis (16%) and somatoform vertigo (16%). Benign paroxysmal vertigo was diagnosed in 4 patients (11%) and paroxysmal torticollis was diagnosed in a 1-year-old child. In 8% (3 patients) of cases, the dizziness had a post-traumatic origin: 1 canalolithiasis of the posterior semicircular canal and 2 labyrinthine concussions, respectively. Menière's disease was diagnosed in 2 cases. A bilateral vestibular failure of unknown origin caused chronic dizziness in 1 patient. In conclusion, this algorithm could represent a good tool for guiding clinical suspicion to correct diagnostic assessment in dizzy children where no neurological findings are detectable. The algorithm has just a few simple steps, based mainly on two aspects to be investigated early: temporal features of vertigo and presence of hearing impairment. A different algorithm has been proposed for cases in which a traumatic origin is suspected.

Benign tumours affecting the deep lobe of the parotid gland: how to select the optimal surgical approach.

Many types of approaches allow extra-capsular dissection in the deep parotid parenchyma in the treatment of benign tumours. A transcervical approach (TCA), transparotid approach (TPA) and a combined transcervical-transparotid approach (TPTCA) are the three main procedures performed to expose the deep parenchyma. We conducted a retrospective chart review enrolling 24 consecutive patients treated for benign tumours affecting the deep lobe of the parotid. Review of the surgical data was accompanied by careful follow-up to establish surgical morbidity, functional (Frey's Syndrome and first-bite syndrome) and aesthetical outcomes. A TPA was performed in the majority of cases; in 26% superficial parotidectomy was not required (selective deep parotidectomy). Minor's test showed a low rate of Frey's syndrome (3 cases of 23, 13%). No long-lasting first-bite syndrome was reported. Some additional procedures were easily performed in order to improve aesthetical results (rotational flap of sternocleidomastoid muscle, free abdominal fat transfer); these had the same results as selective deep parotidectomy. TCA (or TPTCA) ensures the best control of the facial nerve, providing good exposure and good functional and aesthetical results (without sparing the superficial parenchyma if additional techniques are performed with the aim of reducing skin depression in the treated area). The choice of the approach should have only the aim of safe resection and should not be influenced by aesthetical outcome; the craniocaudal level of the tumour seems to be the best indicator of the feasibility of the procedure also considering the branches of the facial nerve. In our experience, mandibulotomy can always be avoided.

Long-term follow up of sudden sensorineural hearing loss patients treated with intratympanic steroids: audiological and quality of life evaluation.

OBJECTIVE: To evaluate the long-term stability of intratympanic steroids and investigate the 'real' impact of sudden sensorineural hearing loss on patients. METHOD: A total of 14 patients treated with intratympanic steroids were evaluated by audiometric and vestibular examinations. The modified Glasgow Benefit Inventory was used to evaluate quality of life changes after intratympanic steroid treatment. RESULTS: There was no significant difference between pure tone average post-intratympanic steroids and at follow up. The general Glasgow Benefit Inventory score was not significantly associated with the presence of tinnitus or dizziness, or with patient age. The change in pure tone average after intratympanic steroid treatment did not correlate with social or physical scores, but correlated strongly with the general Glasgow Benefit Inventory score (p = 0.0023). Intratympanic steroid administration led to a stable improvement in hearing. Quality of life assessment showed that patients can feel satisfaction regardless of the hearing outcome. Patients who regained a social hearing level expressed greater satisfaction than patients without serviceable hearing. Overall, quality of life improvement was not related to hearing improvement. CONCLUSION: Sudden sensorineural hearing loss is devastating. Considering the audiological effects alone ignores the 'human' perspective. Audiological success can correlate with poor quality of life outcome.

aEEG in preterm infants.

Over the last decade, the survival of premature babies has improved dramatically. Such infants, especially those with extremely low birth weight, are still affected by dangerous complications occurring during the neonatal period that often cause brain damage. Intraventricular-intraparenchymal haemorrhage (IVH-IPH), periventricular leukomalacia (PVL), seizures, meningitis and hypoxic-ischaemic encephalopathy are the most common complications. Such problems require more specialized monitoring of brain function during this critical period. In recent years, many studies on very premature infants have shown that aEEG has a high predictive value for both short-term and long-term outcome. In fact, it has been proven that some types of background activity patterns, the absence of a sleep-wake cycle, and seizure activity are related to the onset of early complications such as IVH-IPH and PVL. Most recent studies have shown that an aEEG performed in the early hours or during the first days of life can predict the neurobehavioural development of preterm infants at 2 years and 3 years (Bayley Scale). In particular our study demonstrates that loss of sleep-wake cycling, shown by aEEG, has a high positive predictive value for the development of posthaemorrhagic hydrocephalus (PPH) in preterm infants with IVH; therefore, the study of cerebral background activity and in particular of sleep-wake cycling can be used as an early prognostic tool in patients at risk of PPH.

Intratympanic methylprednisolone as first-line therapy in sudden sensorineural hearing loss: preliminary results from a case-control series.

BACKGROUND: Sudden sensorineural hearing loss is a true audiological emergency, and its management is much discussed. Currently, no single therapy has been proven effective according to evidence criteria. Recently, intratympanic application of steroids has been increasingly used in refractory cases; however, it has only rarely been reported as first-line therapy. MATERIALS AND METHODS: Twenty consecutive patients with sudden sensorineural hearing loss treated between July 2008 and January 2010 were enrolled in this prospective, case-control study. Ten patients were treated with intratympanic steroids and 10 with systemic 'shotgun' therapy (including steroids, pentoxifylline, low molecular weight heparin and vitamin E). The two groups were homogeneous in all respects. Pure tone averages were assessed before and after treatment for both groups. RESULTS: There were no statistically significant differences between the two groups. CONCLUSION: Intratympanic steroids seem to offer a valid alternative to systemic therapy, with few risks, in sudden sensorineural hearing loss patients, and we recommend their use as first-line therapy.

Neonatal thrombosis.

Thrombosis is a special problem of the neonatal period, particularly in premature sick neonate, where it occurs with greater frequency than at other times of childhood. The aim of this article is to review the recommendations for the diagnosis and treatment of neonatal thrombosIs.

A rare case of primary systemic amyloidosis of the neck with massive cervical lymph node involvement: a case report and review of the literature.

Amyloidosis is a term applied to a diverse group of disorders that share the deposition of amyloid protein in various extracellular tissues. Systemic amyloidosis may involve almost any organ system in the body including regions in the head and neck; however, neck lymph node involvement is rare, with only five previous cases reported. We present the case of a primary systemic AL amyloidosis with hepatic, cervical, retroperitoneal, axillary and inguinal lymphnode localizations, unresponsive to medical therapy and treated with a surgical approach followed by autologous bone marrow transplantation. We review the pertinent literature with exclusive attention to the otorhinolaryngologic aspect.

Correlations between transversal discrepancies of the upper maxilla and oral breathing.

AIM: The aim of the study was to evaluate the relationship between malocclusion with cross-bite and permeability of the upper airways, and to observe the cephalometric changes of the rhinopharyngeal space after rapid palatal expansion therapy. MATERIALS AND METHODS: The sample consisted of 17 patients (age 9-12) of which 10 were males, followed up for a period of 1 year at the Department of Paediatric Dentistry of the Dental Clinic of the University of Pisa. Clinical, radiographical and otolaryngological examinations were carried out before treatment with palatal expansor. After expansor activation, each patient underwent an otolaryngological and orthodontic evaluation followed by rhinomanometry, and, in the cooperating children, endoscopy was also performed. After 6 and 12 months from the beginning of the treatment, each patient was examined again and the radiographic examination was repeated. RESULTS AND CONCLUSION: The cephalometric analysis exhibited an increase of the rhinopharyngeal space in 16 children. Furthermore all the 17 patients showed, after therapy, an increase of the transverse dimension of the upper jaw, measured on the postero-anterior teleradiography. On the other hand, the otolaryngological examination, and in particular rhinomanometry, exhibited an improvement of the flow and of right and left nasal resistance only in 3 children, while in 6 children the graph remained unchanged, and in 8 children it worsened. The results show that the rapid palatal expansion produces an improvement of the transversal skeletal discrepancy, and an improvement of the permeability of the upper airways. To make a correct diagnosis lateral and postero-anterior teleradiography, and a cephalometric analysis are needed; instead the otolaryngological examination in our opinion it is not an essential diagnostic examination for this kind of pathology.

Frontal mucocoele communicating with an arachnoid cyst of the anterior cranial fossa.

Mucocoeles usually involve the frontal sinus and can extend to the orbit or intracranially. In this case symptoms and radiological findings were typical of a left frontal mucocoele with intracranial extension. Intraoperative findings were compatible with a left frontal mucocoele communicating with an arachnoid cyst of the anterior cranial fossa.

Bilateral, isolated, lateral semicircular canal malformation without hearing loss.

HYPOTHESIS: Inner-ear malformations are frequently found in patients with sensorineural hearing loss. However, isolated anomalies of the vestibular part of the inner ear are seldom described, and for this reason their impact on balance is poorly understood. CARE REPORT: We present the case of a 38-year-old Caucasian man with recurrent vestibular complaints, with a sensation of linear tilting, but no hearing impairment. Clinical and neuro-otological examinations showed peripheral involvement of the vestibular system, while audiological investigation was within normal limits. High-resolution magnetic resonance imaging of the inner ear, with three-dimensional reconstruction, demonstrated isolated vestibular anomalies involving both the lateral semicircular canal and the utricle. CONCLUSIONS: Bearing in mind this case, we speculate that isolated vestibular malformation may not be as rare as previously thought, and should be investigated with the aid of sophisticated imaging techniques. A review of the relative literature, focussing attention on the molecular aspects, is also reported.
