Universal Newborn Screening for Congenital Cytomegalovirus Infection - From Infant to Maternal Infection: A Prospective Multicenter Study.

Introduction: Most infants at risk for cytomegalovirus (CMV)-associated sensorineural hearing loss (SNHL) are unrecognized because of the absence of a universal neonatal CMV screening. The search of CMV-DNA by molecular methods in salivary swabs was demonstrated to be a reliable approach. This study describes the results obtained by carrying out a universal screening for congenital CMV (cCMV) infection including all live-born newborns in three Italian sites, as well as the therapeutic interventions and clinical outcome of the CMV-infected neonates.

Chronic-Relapsing cutaneous leukocytoclastic vasculitis in a young patient with reduced EBV-specific T cell response using enzyme-linked immunospot (ELISPOT) assay successfully treated with Valaciclovir.

Among different pathogens, opportunistic viral infection caused by EBV is particularly relevant. This gammaherpesvirus, belonging to the Herpesviridae family, may complicate the disease course in different clinical settings by inducing pathological EBV pictures in patients with a defective immunologic response. Our report evaluated EBV-specific T cell responses by IFN- γ ELISPOT assay, which revealed defective EBV specific immunological response.

Case Report: Molecular Detection of Dirofilaria repens in an Italian Patient after a Stay in Tanzania.

A 35-year-old man was admitted to a hospital in the south of Italy because of a periocular nodule and subpalpebral edema. The patient reported having been stayed in Tanzania five months before. Hematologic parameters were within the normality range, the Acanthocheilonema viteae ELISA did not detect significant levels of antifilarial IgG, and no further symptoms were described.

Collaborative national multicenter for the identification of conversion factors from copies/mL to international units/mL for the normalization of HCMV DNA load.

The present multicentric (n = 11 laboratories) study aimed to identify conversion factors from copies/mL to international units (IU)/mL for the normalization of HCMV DNA load using the first WHO International Standard for HCMV nucleic acid amplification techniques and to enhance interlaboratory agreement of HCMV DNA quantification methods. Study protocols for whole blood and plasma (extraction and amplification) were performed to calculate conversion factors from HCMV DNA copy number to IU. The greatest variability was observed in samples with lower HCMV concentrations (3.

Congenital and proposal of a new classification for the likelihood of primary maternal infection: analysis of 375 cases in Southeast Italy.

The aim of this study was to propose a classification in order to stratify the probability of an acute Toxoplasma infection in pregnancy and to estimate the risk of vertical transmission. We evaluated the likelihood of a primary maternal infection according to the Lebech classification and to the modified-Lebech classification proposed for our group of 375 patients referred for a suspected primary maternal infection. Fetal diagnosis included the examination of amniotic fluid by PCR to detect Toxoplasma DNA as a confirmation test.

Leukocytoclastic Vasculitis Associated with HHV6-A/ciHHV6-A and HHV6-B Coinfection in an Immunocompetent Woman.

Background And Objective: Leukocytoclastic vasculitis (LCV) is a small vessel vasculitis that can be limited to the skin but may also affect other organs. Often, its cause is unknown. LCV has previously been reported to occur with the reactivation of human herpesvirus 6 (HHV-6).

Atypical Herpetic Whitlow: A Diagnosis to Consider.

Context: Herpetic whitlow is caused by herpes virus (type1 or 2) during primary infection or as result of autoinoculation. Commonly, it is caused by HSV-2 in adults with positive history for genital infection.

Case Description: We report the case of a 44-year-old woman that came to our attention with a 3- year history of recurrent cutaneous eruption on the ring finger of her left hand associated to lymphangitis of the homolateral arm.

Nation-wide measure of variability in HCMV, EBV and BKV DNA quantification among centers involved in monitoring transplanted patients.

Background: Inter-laboratory variability in quantifying pathogens involved in viral disease following transplantation may have a great impact on patient care, especially when pre-emptive strategies are used for prevention.

Objectives: The aim of this study was to analyze the variability in quantifying CMV, EBV and BKV DNA from 15 virology laboratories of the Italian Infections in Transplant Working Group (GLaIT) involved in monitoring transplanted patients.

Study Design: Panels from international Quality Control programs for Molecular Diagnostics (QCMD, year 2012), specific for the detection of CMV in plasma, CMV in whole blood (WB), EBV and BKV were used.

Zoster ... "a lmost" ... sine herpete: diagnostic utility of real time-polymerase chain reaction.

Zoster sine herpete is a particular form of varicella zoster virus (VZV) infection characterized by segmental pain and dysesthesia, without any cutaneous lesions ever becoming perceptible. This report describes the case of a female patient, presenting with intercostal pain associated with a single papulo-vesicular lesion localized within the same area. Thanks to such a lesion, real time-polymerase chain reaction (PCR) analysis on vesicle fluid swab was possible, thus revealing a significant number of VZV genome copies.

High level immunity against poliomyelitis in African and Asian refugees in southern Italy.

The aim of this study was to evaluate the level of poliomyelitis immunization in refugees residing in the Asylum Seeker Center in Bari. The study was carried out during 2008 and involved 573 refugees. An antibody titer >or=1:8 was found in 99.

Serological survey on immunity status against polioviruses in children and adolescents living in a border region, Apulia (Southern Italy).

Background: In 1988 the World Health Assembly adopted the goal to eradicate poliomyelitis by routine immunization using Oral Polio Vaccine (OPV). On 21 June 2002 the WHO European Region was declared polio-free. In 2008 poliomyelitis is still endemic in 4 countries (Nigeria, India, Pakistan, and Afghanistan), where 1201 new cases were registered in 2007; 107 sporadic cases were also notified in countries where poliovirus is not endemic.

Unsafe tap water in households supplied from groundwater in the Salento Region of Southern Italy.

Although the fractured aquifer of the Salento supplies over 80% of the drinking water requirements of the local population, its exposure to pollution has recently increased. In recent years, owing to the arid climate and droughts, the spreading of wastewater on soil for irrigation has become much more frequent. Consequently, hazardous and pathogenic microorganisms released with wastewater have been transported into the subsoil and have contaminated groundwater.

Multicity Italian study of congenital cytomegalovirus infection.

Background: Cytomegalovirus (CMV) infection is the most frequent congenital infection in humans. Its prevalence and the frequency of disabling sequelae must be assessed in different populations to permit the formulation or assessment of preventive measures.

Objectives: To check the prevalence of congenital infection and seroprevalence in Italy; to verify the rate of sensorineural hearing loss (SNHL) in infected infants; and to assess the proportion of children with SNHL attributable to congenital CMV infection.

Epstein-barr virus induced cellular changes in nasal mucosa.

Unlabelled: A 21-year-old man presented with nasal obstruction of the right nasal fossa of 1 year duration. Nasal endoscopy revealed in the right inferior turbinate head a rounded neoplasm about 1 cm in diameter. Cytologic study of a nasal scraping specimen disclosed numerous clusters containing columnar cells with cytomegaly, prominent multinucleation, markedly sparse shortened cilia; the cytoplasm contained an acidophil area and a small round area that stained poorly; cells with a large intracytoplasmic vacuole that was acidophil and PAS+.

Recalcitrant scalp folliculitis: a possible role of herpes simplex virus type 2.

We report the case of a 70-year-old man with a 1 year history of relapsing folliculitis of the scalp. Bacteriological, mycological and the Tzanck tests from the lesions were negative. Histopathological study showed suppurative perifollicular flogosis.

Relapsing herpes simplex-2 folliculitis in the beard area.

We describe the case of a 52-year-old immunocompetent man with recurrent folliculitis on the left cheek, associated with intense pain. Bacteriological, mycological and Tzanck tests from the lesions were negative. Histopathological study showed an aspecific flogosis pattern.

Modification of CMV DNA detection from dried blood spots for diagnosing congenital CMV infection.

Background: Detection of viral DNA in dried blood spots using the Guthrie card (DBS test) is a reliable and practical method of diagnosing congenital cytomegalovirus (CMV) infection. The test lends itself to epidemiological studies to establish the prevalence of the infection, but also to neonatal screening for secondary prevention of sequelae. These applications would be facilitated if it were possible to use smaller samples and do the test on pools of individual cases.
