Abstract
Tinea capitis is a common disease in children but rare in newborns younger than 1 month of age. Only 29 cases of tinea capitis in newborns have been described in indexed literature from 1990 until now. While antifungal agents can be used topically and systemically, systemic antifungal therapy is generally accepted as the treatment of choice for tinea capitis due to limited penetration of topical agents into the hair follicle. However, there is a lack of data on the use of systemic antifungal agents in newborns, and there are reports of successful treatment of tinea capitis in newborns using only topical therapy. In this paper, we present a case of tinea capitis in a 29-day-old female baby and review the previous 29 reported cases.

Abstract
BACKGROUND Numerous reports of resistance to terbinafine in Trichophyton spp. from all over the world are arousing justified attention and concern. Point mutations in the gene that encodes the squalene epoxidase (SQLE) enzyme are responsible for these therapeutic resistances. OBJECTIVES Primary objective of the study was to describe first isolates of Trichophyton spp. resistant to terbinafine among the patients treated between September 2019 and June 2022 at the Dermatology Units of Ospedale Maggiore Policlinico and San Bortolo Hospital. Secondary objective was to study the resistance mechanism. METHODS Patients with confirmed Trichophyton spp. infection has been treated with systemic and topical terbinafine. Patients were then re-evaluated 12 weeks after the therapy. Patients with incomplete or absent response to terbinafine underwent a new skin scraping for direct mycological examination, new identification of dermatophyte species from culture and MALDI-TOF, molecular species identification, antifungal susceptibility testing and molecular analysis of SQLE gene. RESULTS We identified five patients without clinical response to treatment with terbinafine. The DNA sequencing of the ITS region identified one Trichophyton rubrum and four Trichophyton indotineae. The T. rubrum strain showed minimum inhibitory concentration (MIC) (90% growth inhibition) of 4 mg/L for terbinafine. The four T. indotineae strains showed a MICs range of 0.25-4 mg/L for terbinafine. The analysis of the SQLE gene in the T. rubrum strain showed a nucleotide substitution generating a missense mutation (L393F). The SQLE gene sequencing in the T. indotineae strains showed a nucleotide substitution generating a missense mutation (F397L) in two strains, a nucleotide substitution L393S in one strain and a nucleotide substitution F415C in another strain. CONCLUSIONS We report the first cases of terbinafine-resistant Trichophyton isolates in the Italian population. Solid antifungal management programs will be needed to promote more responsible use of antimycotics and preserve their therapeutic efficacy to control antifungal resistance.

Abstract
BACKGROUND In August 2020, in the context of COVID-19 pandemics, an autochthonous dengue outbreak was identified for the first time in Italy. METHODS Following the reporting of the index case of autochthonous dengue, epidemiological investigation, vector control and substances of human origin safety measures were immediately activated, according to the national arbovirus surveillance plan. Dengue cases were followed-up with weekly visits and laboratory tests until recovery and clearance of viral RNA from blood. RESULTS The primary dengue case was identified in a young woman, who developed fever after returning from Indonesia to northern Italy, on 27 July 2020. She spent the mandatory quarantine for COVID-19 at home with relatives, six of whom developed dengue within two weeks. Epidemiological investigation identified further five autochthonous dengue cases among people who lived or stayed near the residence of the primary case. The last case of the outbreak developed fever on 29 September 2020. Dengue cases had a mild febrile illness, except one with persistent asthenia and myalgia. DENV-1 RNA was detected in blood and/or urine in all autochthonous cases, up to 35 days after fever onset. All cases developed IgM and IgG antibodies which cross-reacted with West Nile virus (WNV) and other flaviviruses. Sequencing of the full viral genome from blood samples showed over 99% nucleotide identity with DENV-1 strains isolated in China in 2014-2015; phylogenetic analysis classified the virus within Genotype I. Entomological site inspection identified a high density of Aedes albopictus mosquitoes, which conceivably sustained local DENV-1 transmission. Aedes koreicus mosquitoes were also collected in the site. CONCLUSIONS Areas in Europe with high density of Aedes mosquitoes should be considered at risk for dengue transmission. The presence of endemic flaviviruses, such as WNV, might pose problems in the laboratory diagnosis.

Abstract
Purpose: To compare the visual outcome in terms of multifocality in Manual Small Incision Cataract Surgery (MSICS) with and without intraoperative manipulation of corneal curvature. Methods: This was a prospective study on 80 subjects (80 eyes) who underwent MSICS with monofocal posterior chamber intraocular lens (PCIOL) implantation between January 2018 and October 2019. Intraoperative manipulation of corneal curvature using viscoelastics was performed during MSICS in 40 subjects (cases) while this intraoperative manipulation was not performed in the remaining 40 subjects (controls). Uncorrected distance visual acuity (UDVA) and uncorrected near visual acuity (UNVA) were compared at day 1, 7, 30 and 180postoperatively. Results: At 1 month and 6 months of follow up, UDVA was comparable in the 2 groups. UNVA was better in cases than controls at 1 month and6 months (P < 0.001). At 6 months of follow up,76% of cases with UDVA of 6/9 or better had UNVA of N8 while only 15% of controls with UDVA of 6/9 or better had UNVA of N8 (P <0.001). Mean near add requirement to achieve a best corrected near vision (BCNV)of N6 at 6 months was significantly lesser (P =0.002) in cases (+2.05 D) compared to controls (+2.43D). Conclusion: MSICS with intra operative manipulation of corneal curvature resulted in better unaided near visual acuity compared to that without intra operative manipulation of corneal curvature, without compromising unaided distant visual acuity.

Abstract
In August 2020, during the coronavirus disease (COVID-19) pandemic, five locally acquired cases of dengue virus type 1 were detected in a family cluster in Vicenza Province, North-East Italy where Aedes albopictus mosquitoes are endemic. The primary case was an importation from West Sumatra, Indonesia. This is the first outbreak of autochthonous dengue reported in Italy. During the COVID-19 pandemic, screening of febrile travelers from endemic countries is crucial in areas where competent vectors are present.

Abstract
Acoustic noise levels were measured in the Gulf of Catania (Ionian Sea) from July 2012 to May 2013 by a low frequency (<1000Hz) hydrophone, installed on board the NEMO-SN1 multidisciplinary observatory. NEMO-SN1 is a cabled node of EMSO-ERIC, which was deployed at a water depth of 2100m, 25km off Catania. The study area is characterized by the proximity of mid-size harbors and shipping lanes. Measured noise levels were correlated with the passage of ships tracked with a dedicated AIS antenna. Noise power was measured in the frequency range between 10Hz and 1000Hz. Experimental data were compared with the results of a fast numerical model based on AIS data to evaluate the contribution of shipping noise in six consecutive 1/3 octave frequency bands, including the 1/3 octave frequency bands centered at 63Hz and 125Hz, indicated by the Marine Strategy Framework Directive (2008/56/EC).

Abstract
Concern is growing that marine fauna can be affected by noise such as naval sonar, pile driving or geophysical surveys, among others. Literature reports a variety of animal reactions to human noise (from apparently null or negligible to strong). However, conclusive results on its effects on marine mammals at individual and population level are still lacking. In 2015, the Italian Environmental Impact Assessment Commission mandated seismic operators apply a standard scientific protocol comparing marine mammal presence before, during, and after offshore seismic survey. For 60days before and after the survey, marine mammals are monitored using visual and acoustic methods. One or more acoustic autonomous recorders, depending on area size, must also be deployed throughout the three phases for continuous monitoring. Consistent data gathered from many surveys will enable robust statistical analysis of results. Diffusion of this monitoring method internationally would improve the study of far-reaching, intense, low frequency noise.

The aim of the study is the identification of genetic factors that influence the long-term response to interferon-β (IFNβ) (4-year follow-up). We performed a genome-wide association study in 337 IFNβ-treated Italian multiple sclerosis patients at the extreme of treatment response, and we meta-analyzed association effects, integrating results with pathway analysis, gene-expression profiling of IFNβ-stimulated peripheral blood mononuclear cells from 20 healthy controls (HC) and expression quantitative locus (eQTL) analyses. From meta-analysis, 43 markers were associated at P<10-4, and two of them (rs7298096 and rs4726460) pointed to two genes, NINJ2 and TBXAS1, that were significantly downregulated after IFNβ stimulation in HC (P=3.1 × 10-9 and 5.6 × 10-10). We also observed an eQTL effect for the allele associated with favorable treatment response (rs4726460A); moreover, TBXAS1 appeared downregulated upon IFNβ administration (β=-0.39; P=0.02). Finally, we found an enrichment of pathways related to inflammatory processes and presynaptic membrane, the latter with involvement of genes related to glutamatergic system (GRM3 and GRIK2), confirming its potential role in the response to IFNβ.

Abstract
Recent observations of cetacean mass strandings, coincident with anthropogenic sounds emissions, have raised concerns on the potential environmental impact of underwater noise. Cuvier's beaked whale (Ziphius cavirostris) was reported in all the cited stranding events. Within the NATO Marine Mammal Risk Mitigation project (MMRM), multiple interdisciplinary sea trials have been conducted in the Mediterranean Sea with the objective of developing tools and procedures to mitigate the impact of underwater sound emissions. During these cruises, visual observations, passive acoustic detections and environmental data were collected. The aim of this study was to evaluate "a priori" predictions of Cuvier's beaked whale presence in the Alboran Sea, using models developed in the Ligurian Sea that employ bathymetric and chlorophyll features as predictors. The accuracy of these predictions was found adequate and elements are given to account for the uncertainties associated to the use of models developed in areas different from their calibration site.

Abstract
The genus Myroides comprises aerobic, yellow-pigmented, non-motile, non-fermenting gram-negative rods formerly classified as Flavobacterium odoratum. Members of the genus are widely distributed in the environment, especially in water, and usually behave as low-grade opportunistic pathogens, having been found to cause urinary tract infection, endocarditis, ventriculitis, and cutaneous infections in severely immunocompromised patients. We report a case of soft tissue infection, septic shock, and pneumonia due to M. odoratimimus in an immunocompetent male. To our knowledge, this is the first description of life-threatening infection caused by this organism in an immunocompetent host. We have also reviewed the medical literature on the genus Myroides.

Abstract
Acquired perforating dermatoses (APD) is an uncommon skin disorder seen in patients with diabetes mellitus, chronic kidney disease, or both together. We present the clinicopathological features of APD in patients with diabetic kidney disease and discuss the recent advances in management. We retrospectively analyzed the data of 8 patients with APD presenting to our center. All patients were known cases of Type 2 diabetes and chronic kidney disease requiring maintenance dialysis. Acquired perforating dermatoses was diagnosed based on clinical presentation of itchy, keratotic papulonodular lesions, and characteristic histopathological features of transepithelial elimination on skin biopsy. The patients were subdivided into 4 types of APD based on the biopsy features. All our patients had Type 2 diabetes over 5 years duration and were on maintenance dialysis for more than 6 months before presentation. Acquired perforating dermatoses symptoms appeared 2 to 6 months before presentation. The majority of patients (6/8) had a subtype of reactive perforating collagenosis. All the patients showed significant resolution with topical glucocorticoid therapy. Acquired perforating dermatoses is a skin complication seen in Type 2 diabetes, chronic kidney disease, or when both are present together. Early identification and therapy prevents the associated morbidity.

Abstract
A distinctive vocalization of the sperm whale, Physeter macrocephalus (=P. catodon), is the coda: a short click sequence with a distinctive stereotyped time pattern [Watkins and Schevill, J. Acoust. Soc. Am. 62, 1485-1490 (1977)]. Coda repertoires have been found to vary both geographically and with group affiliation [Weilgart and Whitehead, Behav. Ecol. Sociobiol. 40, 277-285 (1997)]. In this work, the click timings and repetition patterns of sperm whale codas recorded in the Mediterranean Sea are characterized statistically, and the context in which the codas occurred are also taken into consideration. A total of 138 codas were recorded in the central Mediterranean in the years 1985-1996 by several research groups using a number of different detection instruments, including stationary and towed hydrophones, sonobuoys and passive sonars. Nearly all (134) of the recorded codas share the same "3+1" (/// /) click pattern. Coda durations ranged from 456 to 1280 ms, with an average duration of 908 ms and a standard deviation of 176 ms. Most of the codas (a total of 117) belonged to 20 coda series. Each series was produced by an individual, in most cases by a mature male in a small group, and consisted of between 2 and 16 codas, emitted in one or more "bursts" of 1 to 13 codas spaced fairly regularly in time. The mean number of codas in a burst was 3.46, and the standard deviation was 2.65. The time interval ratios within a coda are parameterized by the coda duration and by the first two interclick intervals normalized by coda duration. These three parameters remained highly stable within each coda series, with coefficients of variation within the series averaging less than 5%. The interval ratios varied somewhat across the data sets, but were highly stable over 8 of the 11 data sets, which span 11 years and widely dispersed geographic locations. Somewhat different interval ratios were observed in the other three data sets; in one of these data sets, the variant codas were produced by a young whale. Two sets of presumed sperm whale codas recorded in 1996 had 5- and 6-click patterns; the observation of these new patterns suggests that sperm whale codas in the Mediterranean may have more variations than previously believed.

Abstract
Antibodies to Chlamydia pneumoniae (IOL-207) were studied by the microimmunofluorescence (MIF) assay and in vitro neutralization in serum samples from 230 healthy adults and 332 patients at risk of C. pneumoniae infection. In the MIF test, the prevalence of immunoglobulin G (IgG) antibody was 53.9% among healthy subjects and 40.7% in the patients. An MIF antibody titre of > or = 1 : 512, consistent with acute infection by C. pneumoniae was documented in 23 out of 332 patients, and in none of the healthy adults. C. pneumoniae complement-dependent neutralizing antibody was detected in 25.8% and 31.2%, respectively of MIF-positive sera from healthy subjects and patients. The neutralizing antibody detection rate was 52.2% among the 23 patients with MIF titres of > or = 1 : 512. Complement-independent neutralization was observed in only 5 sera from healthy subjects and in 3 sera from patients. The complement-dependent neutralizing ability of sera significantly (p < 0.001) correlated with MIF titres.

Abstract
Analysis by two-dimensional gel electrophoresis of the N-laurylsarkosinate(Sarkosyl)-insoluble envelope complexes of L-[35]S-cysteine-labeled elementary bodies of Chlamydia pneumoniae strain IOL-207, Chlamydia trachomatis serovar LGV2, D, and F, and Chlamydia psittaci strain 6BC showed differences in the molecular charges of chlamydial outer membrane proteins. The apparent isoelectric point (pI) of the major outer membrane protein of C. pneumoniae strain IOL-207 was 6.4, whereas the pI of the major outer membrane protein of the C. trachomatis and C. psittaci strains differed little from one another, ranging from 5.3 to 5.5. The 60-kDa cysteine-rich protein of C. pneumoniae was the only 60-kDa chlamydial protein with a pI value (5.9) more acidic than that of the corresponding major outer membrane protein. As a general rule, the charges of both the 60-kDa and the low-molecular-mass (12-15 kDa) cysteine-rich proteins were widely variable, depending on the strain. However, in each individual strain, the variation of the charge of the 60-kDa protein had a compensatory change in the low-molecular-mass cysteine-rich protein.

Abstract
The influence of centrifugation on the infectivity of Chlamydia pneumoniae IOL-207 was compared with seven serovars of C. trachomatis biovar trachoma, the three serovars of C. trachomatis biovar lymphogranuloma and four C. psittaci strains. Prolonged centrifugation from 1 to 4 hours resulted in a 3-fold increase in the infectivity of C. pneumoniae and variable or no increase in the infectivity of the other Chlamydia strains studied. These findings indicate that a 4 hour centrifugation of C. pneumoniae is recommended to improve the isolation procedures of this organism in cell cultures.

Abstract
We compared a commercially available PCR assay (Amplicor, Roche, Switzerland) and tissue culture isolation for the detection of C. trachomatis in urethral and/or endocervical swabs. Of the 200 patients studied (130 men and 70 women) PCR and tissue culture gave concordant results in 199 cases; in one case PCR was positive and culture negative. The Amplicor PCR assay proved fast and sensitive and suitable for routine use in most clinical microbiology laboratories.
