Pediatric voice disorders are typically a low-incidence population in the average caseload of clinicians working within school and general clinic settings. This occurs despite evidence of a fairly high prevalence of childhood voice disorders and the multiple impacts the voice disorder may have on a child's social development, the perception of the child by others, and the child's academic success. There are multiple barriers that affect the identification of children with abnormal vocal qualities and their access to services. These include: the reliance on school personnel, the ability of parents and caretakers to identify abnormal vocal qualities and signs of misuse, the access to specialized medical services for appropriate diagnosis, and treatment planning and issues related to the Speech-Language Pathologists' perception of their skills and competence regarding voice management for pediatric populations. These barriers and possible solutions to them are discussed with perspectives from the school, clinic and university settings.

Abstract. Background: Insufficient evidence exists to support the safety of carotid endarterectomy (CEA) following intravenous thrombolysis (IVT) for acute ischaemic stroke. Our study aimed to report a single-centre experience of patients treated over a five-year period. Patients and methods: Departmental computerised databases were interrogated to identify patients who suffered an ischaemic stroke and subsequently underwent thrombolysis followed by CEA. Mortality and stroke within 30 days of surgery were defined as the primary outcome end points. Results: Over a five-year period, 177 out of a total of 679 carotid endarterectomies (26 %) were performed in patients presenting with acute ischaemic stroke. Twenty-five patients (14 %) received IVT prior to CEA in the form of alteplase. Sixty percent of patients were male with a mean age of 68 years. Sixteen patients (64 %) underwent CEA within 14 days of IVT and the median interval between thrombolysis and CEA was 7.5 days (range, 3–50 days). One female patient died of a further intraoperative stroke within 30 days of surgery, yielding a mortality rate of 4 %. Two patients (8 %) suffered from cardiac complications postoperatively resulting in a short high dependency unit stay. Another two patients (8 %) developed local wound complications, which were managed conservatively without the need for re-operation. The median hospital length of stay was 4.5 days (range, 1–33 days). Conclusions: Our experience indicates that CEA post-thrombolysis has a low incidence of mortality. Further high quality evidence is required before CEA can be routinely recommended following IVT for acute ischaemic stroke.

Low Incidence

Italy is considered a low incidence country for tick-borne encephalitis (TBE) in Europe. Areas at higher risk for TBE in Italy are geographically clustered in the forested and mountainous regions and provinces in the north east part of the country, as suggested by TBE case series published over the last decade.

Low Incidence

Italy is considered a low-incidence country for tick-borne encephalitis (TBE) in Europe.1 Areas at higher risk for TBE in Italy are geographically clustered in the forested and mountainous regions and provinces in the north east part of the country, as suggested by TBE case series published over the last decade.2-5 A national enhanced surveillance system for TBE has been established since 2017.6 Before this, information on the occurrence of TBE cases at the national level in Italy was lacking. Both incidence rates and the geographical distribution of the disease were mostly inferred from endemic areas where surveillance was already in place, ad hoc studies and international literature.1
