Fingertip nail bed injuries in children: Comparison of suture repair versus glue (2-octylcyanoacrylate) with 1-year follow-up
International audienceThe main objective of this study was to compare the medium-term results of nail bed repair in children using glue (2-octylcyanoacrylate) versus absorbable sutures. The secondary objective was to compare the results of treatment in the emergency room versus the operating room. This retrospective review of 74 fingertip nail bed lacerations (68 children) evaluated the appearance and pain at the last follow-up visit (minimum of 1 year), and the operating time. Mean age was 3.3 years at time of injury (range 10 months-13 years), with a mean follow-up of 2.6 (1-7) years. Thirty-six nail beds were repaired with glue; 38 were sutured. The clinical outcomes in the two groups were similar. The rate of nail dystrophy was 14% (5% major) regardless of the technique. Nail bed repair time was significantly shorter in the glue group (10.2 vs. 20.3min, p<0.001). Forty-five repairs were performed in the operating room and 29 in the emergency room. The complication rate (early infections) was significantly higher in patients treated in the emergency room. Tissue adhesive (2-octylcyanoacrylate glue) is a reliable option for repairing nail bed lacerations, both in terms of outcomes and speed of repair. Treatment in the operating room is preferable
Active volcano-tectonic deformations: a 3D seismic reflection experiment in the resurgent dome of the NYT Caldera (Pozzuoli Bay, Campi Flegrei, Naples)
An ultra-resolution, 3D seismic reflection data cube was collected during an oceanographic cruise organized
in the frame of a joint project involving Italian research institutions, the University of Palermo, Catania
and Napoli, CNR of Napoli and INGV Roma, and two companies, the Geo Marine Survey System (The
Netherlands) and GeoSurvey (Portugal). The data acquisition approach charted during this cooperation was
based on innovative technologies for the offshore imaging of stratigraphy and structures at continental margins
with horizontal and vertical resolution at decimetric scale. In this work, we present the methodology used
for the 3D HR-seismic reflection data acquisition and the preliminary interpretation of the 3D seismic cube.
The 3D seismic data were acquired onboard the N/O Minerva Uno by using an innovative data acquisition
equipment composed by two sparker sources fired in flip-flop mode, and eight HR 48-channel, slant streamers,
with group spacing variable from 1 to 2 meters, at 10 kHz sampling rate. An innovative navigation system was
used to perform all necessary computations to determining real-time positions of sources and receivers. The
investigated area is located in the central-northern part of the Pozzuoli (Naples) Bay that represents the offshore
prolongation of the Campi Flegrei caldera. Here, an antiformal structure, corresponding to the resurgent dome
associated with Neapolitan Yellow Tuff (NYT) caldera, characterizes the structure and morphology of the
inner shelf (e.g. Sacchi et al., 2014). Previous research works based on 2 or 2.5D high-resolution reflection
seismics (e.g. Steinmann et al., 2018), have documented the presence of collapse faults on the summit (apical
graben) of the resurgent dome. However the 3D pattern of this structure and the style of ground deformation
are still poorly defined. The results of this study provide the base for the quantitative analysis of active faults
and stress field that are important for understanding the volcano-tectonic process responsible for the formation
of the resurgence dome inside the caldera and its related hazard
