Adopting a Diary to Support an Ecological Assessment of Neuropsychiatric Symptoms of Dementia.

Neuropsychiatric symptoms (NPS) are one of the most challenging issues in the management and care of people with dementia. Their accurate assessment is thus crucial for properly approaching subjects with cognitive disorders in the clinical setting. In parallel, the correct evaluation of NPS is also particularly relevant in the research field where they serve as critical indicators for measuring the efficacy of interventions against cognitive disorders. However, the study of NPS is extremely challenging given their extreme inter- and intra-individual variability. Moreover, the available assessment tools are often inadequate to fully capture their complexity and phenotypic expression. Based on these considerations, novel modalities for the assessment and measurement of NPS may be important to identify and develop. In this regard, a promising alternative (or, at least, a complementary aid) to traditional scales and questionnaires might be constituted by diaries. In the present article, we discuss the potential advantages and implications that may result from the adoption of this kind of instruments for the ecological assessment of NPS in subjects with dementia.

Measles outbreak on a cruise ship in the western Mediterranean, February 2014, preliminary report.

A measles outbreak occurred in February 2014 on a ship cruising the western Mediterranean Sea. Overall 27 cases were reported: 21 crew members, four passengers.For two cases the status crew or passenger was unknown. Genotype B3 was identified. Because of different nationalities of cases and persons on board,the event qualified as a cross-border health threat. The Italian Ministry of Health coordinated rapid response.Alerts were posted through the Early Warning and Response System.

Response to the 2009 influenza A(H1N1) pandemic in Italy.

In Italy, the arrival of the 2009 pandemic influenza A(H1N1) virus triggered an integrated response that was mainly based on the 2006 National Pandemic Preparedness and Response Plan. In this article we analyse the main activities implemented for epidemiological surveillance, containment and mitigation of the pandemic influenza and the lesson learned from this experience. Overall, from week 31 (27 July ­ 2 August) of 2009 to week 17 (26 April ­ 2 May) of 2010, we estimate that there were approximately 5,600,000 cases of influenza-like illness (ILI) who received medical attention (with almost 2,000 laboratory-confirmed cases of pandemic influenza from May to October 2009). A total of 1,106 confirmed cases were admitted to hospital for serious conditions, of whom 532 were admitted to intensive care units. There were 260 reported deaths due to pandemic influenza. Approximately 870,000 first doses of the pandemic vaccine were administered, representing a vaccine coverage of 4% of the target population. One of the possible reasons for the low uptake of the pandemic vaccine in the target population could be the communication strategy adopted, for both the general population and healthcare workers, which turned out to be a major challenge. Active involvement of all health professionals (at local, regional and national level) in influenza pandemic preparedness and response should be encouraged in the future.

Enhanced epidemiological surveillance of influenza A(H1N1)v in Italy.

As of 7 July 2009, a total of 158 laboratory-confirmed cases of influenza A(H1N1)v were reported in Italy, from half of the 21 Italian regions. To date all cases have had symptoms consistent with seasonal influenza and no severe or fatal cases have been reported. An active surveillance of cases has been set up in Italy in order to undertake appropriate measures to slow down the spread of the new virus. This report describes the routine and enhanced surveillance currently ongoing in Italy.

Environmental surveillance of poliovirus in Italy: pilot study.

A pilot study on environmental surveillance of poliovirus included one hundred ninety-six samples (drinking water, surface water, seawater and sewage), collected between 1996 and 1998 in different regions of Italy. Samples were screened for the presence of poliovirus and other enteric viruses. Twelve polioviruses, 35 non polio enteroviruses (NPE) and 51 enteric non entero (NE) viruses were isolated. All poliovirus isolates, namely four type 1, four type 2 and four type 3, were characterised as Sabin-like strains. Thirty-one Coxsackie B and 4 Echo viruses were also detected. The presence of Sabin-like polioviruses in the environment is not unexpected since immunization with only oral poliovirus vaccine was performed in Italy until May 1999, when a sequential schedule consisting of two doses of inactivated polio vaccine (IPV) and two of oral polio vaccine (OPV) was adopted; in July 2002 a schedule consisting of four doses of IPV was adopted. Although this is only a pilot study and the number of samples analysed is limited, so far data from this study so far supports once again evidence of lack of circulating wild poliovirus and is in line with results from AFP surveillance in Italy and stool survey on healthy children.

[Evaluation of the Surveillance System of Acute Flaccid Paralysis in Puglia: 5 years of work]. / Valutazione del Sistema di Sorveglianza delle Paralisi Flaccide Acute in Puglia: cinque anni di attività.

Surveillance of acute flaccid paralysis (AFP) is the milestone to monitor the progress toward poliomyelitis eradication aim, fixed by WHA in 1988. Active AFP surveillance started in Apulia in 1997; this work evaluates five-year period activities. In this period, the total number of cases notified was 48, 7 of which were resident out of Apulia. Twenty-five were males and 23 females; the age ranged between 1 month and 15 years. Any collected serum specimens showed protective antibody levels against polioviruses. Polioviruses type 1 and type 2 Sabin-like were isolated from stool samples collected from two AFP patients. AFP surveillance targets improved in the years, with only exception, in 2001, of second serum specimen collected within 14 days because of children were discharged earlier form the hospitals. Apulia experience demonstrates the achievement of good levels of AFP surveillance targets. System sensitivity has been optimal in 2001 with a number of notified cases threefold the expected value and adequate specimen sampling (80%). Additional involved hospitals and availability of increased and dedicated human resources contributed to this outcome. The effort to achieve WHO targets for AFP surveillance needs to be maintained in next years until global certification of eradication will be declared.

Enterovirus surveillance of Italian healthy children.

Surveillance of acute flaccid paralysis (AFP) is the golden strategy recommended by the WHO to verify the condition of polio eradication in a country. Because of the difficulty to detect all of the expected AFP cases and to reach the target incidence of 1/100,000 requested by WHO, the surveillance of enteroviruses in the population has been adopted by several countries as an important additional method to verify the absence of wild-poliovirus circulation. To complete the results of AFP surveillance set up in Italy in 1996, we have conducted a wild poliovirus surveillance by examining stool samples from 1551 healthy children aged less than 5 years, collected during the period January 1997 to January 1998. The children were from three cities (Parma, Rome and Bari) located in northern, central and southern Italy. Thirty-nine polioviruses, 72 non-polio enteroviruses and 50 enteric, nonentero (NE), viruses were isolated from stool specimens. Polioviruses identified were nine type 1, seven type 2 and twenty-three type 3. Characterization of isolates by both antigenic and molecular methods showed that all polioviruses were of vaccine origin. As expected, most polioviruses, especially types 2 and 3, presented retromutations known to be associated with loss of the Sabin attenuated phenotype. The results of this study support the data obtained from the active AFP surveillance conducted in Italy in the same period--on the absence of paralytic disease due to wild poliovirus--and altogether demonstrate the effectiveness of the vaccination program.

[Flaccid paralysis surveillance in the Latium Region]. / La sorveglianza della paralisi flaccida nella Regione Lazio.

The goal of World Health Organization is to reach the global eradication of poliomyelitis during the first decade of the third millennium. To achieve the certification of the eradication of the disease the main strategy is the Acute Flaccid Paralysis (AFP) surveillance. In Italy the active AFP surveillance was performed at national level since 1997. In the Latium region the active surveillance was performed since January 1997 by the laboratory of virology of Institute of Hygiene G Sanarelli which established a regional hospital network. During the years of survey 7 cases were found in 1997 (0.87/100,000), 4 in 1998 (0.5/100,000), 2 in 1999 (0.25/100,000) and 2 in 2000. No wild polioviruses were detected.

Surveillance of acute flaccid paralysis in Italy: 1996-1997. AFP Study Group. Acute flaccid paralysis.

The last case of poliomyelitis due to transmission of indigenous wild poliovirus occurred in Italy in 1982. To achieve the certification of the eradication of poliomyelitis in Italy, an active surveillance of acute flaccid paralysis (AFP) in the population aged less than 15 years was set up following the World Health Organization (WHO) guidelines. The survey started in 1996 with a pilot study involving 4 out of 21 regions, and was gradually extended to a national level in 1997. The two-year survey identified five patients with diagnosis of vaccine associated paralytic poliomyelitis (VAPP). Polioviruses type 2 and 3 Sabin-like were isolated and characterized in three of them. In the remaining two cases, samples were collected late after the onset of symptoms, and poliovirus could not be isolated. No wild polioviruses were detected during the survey. The rate of non-polio AFP found in Italy in 1997 was 0.61 cases per 100,000, which is lower than the level of 1.0 case per 100,000 considered as acceptable by the WHO. This was mainly due to the delay in organizing the hospital network and starting the active search of AFP cases in the largest and most densely populated regions. Therefore, the overall rate of AFP found in Italy underestimates the global effectiveness of the program, which however will be better evaluated in the next few years. This study is the first systematic attempt to determine the rate of AFP in Italy.

Botulism surveillance in Italy: 1992-1996.

Though a relatively rare disease, botulism can be a serious problem of public health, particularly when connected with the consumption of industrial canned food; moreover, in the last years the shortage of botulism antitoxin has caused some concern in the Public Health Authorities. This work presents the results of a five-year surveillance of botulism in Italy, with the distribution of the cases by Regions (first level administrative units which, in Italy, have administrative and legislative competencies in the sanitary field) and by vehicle of transmission. All the relevant and confirmed botulism outbreaks that occurred in the period under consideration are described.
