CASE REPORT : Dermatobia hominis: Small Migrants Hidden in Your Skin
( Lorenzo Zammarchi ),( Riccardo Viligiardi ),( Marianne Strohmeyer ),( Alessandro Bartoloni ) 대한피부과학회 2014 Annals of Dermatology Vol.26 No.5
Myiasis is a parasitic infestation of vertebrate animal tissues due to maggots of two-winged flies (Diptera) that feed on living or necrotic tissue. Dermatobia hominis occurs widely in tropical parts of Latin America; it is the most common cause of furuncular myiasis in this region. The continuous increase in international travel has increased the possibility of observing this pathology outside endemic countries, especially in travelers returning from the tropics. If clinicians are aware of the possibility of the disease and its treatment options, this dermatosis can be easily managed. However, diagnostic delay is very common because the disease is often misdiagnosed as a bacterial skin infection. Here, we report 2 cases of furuncular myiasis caused by D. hominis in travelers returning to Italy from Latin America. Surgical and noninvasive treatment approaches are also described.

<P>We report on the observation of new properties of secondary cosmic rays Li, Be, and B measured in the rigidity (momentum per unit charge) range 1.9 GV to 3.3 TV with a total of 5.4 x 10(6) nuclei collected by AMS during the first five years of operation aboard the International Space Station. The Li and B fluxes have an identical rigidity dependence above 7 GV and all three fluxes have an identical rigidity dependence above 30 GV with the Li/Be flux ratio of 2.0 +/- 0.1. The three fluxes deviate from a single power law above 200 GV in an identical way. This behavior of secondary cosmic rays has also been observed in the AMS measurement of primary cosmic rays He, C, and O but the rigidity dependences of primary cosmic rays and of secondary cosmic rays are distinctly different. In particular, above 200 GV, the secondary cosmic rays harden more than the primary cosmic rays.</P>

<P>Knowledge of the rigidity dependence of the boron to carbon flux ratio (B/C) is important in understanding the propagation of cosmic rays. The precise measurement of the B/C ratio from 1.9 GV to 2.6 TV, based on 2.3 million boron and 8.3 million carbon nuclei collected by AMS during the first 5 years of operation, is presented. The detailed variation with rigidity of the B/C spectral index is reported for the first time. The B/C ratio does not show any significant structures in contrast to many cosmic ray models that require such structures at high rigidities. Remarkably, above 65 GV, the B/C ratio is well described by a single power law R. with index. Delta = -0.333 +/- 0.014(fit) +/- 0.005(syst), in good agreement with the Kolmogorov theory of turbulence which predicts. Delta = -1/3 asymptotically.</P>

<P>We report the observation of new properties of primary cosmic rays He, C, and O measured in the rigidity (momentum/charge) range 2 GV to 3 TV with 90 x 10(6) helium, 8.4 x 10(6) carbon, and 7.0 x 10(6) oxygen nuclei collected by the Alpha Magnetic Spectrometer ( AMS) during the first five years of operation. Above 60 GV, these three spectra have identical rigidity dependence. They all deviate from a single power law above 200 GV and harden in an identical way.</P>

<P>The variety of isotopes in cosmic rays allows us to study different aspects of the processes that cosmic rays undergo between the time they are produced and the time of their arrival in the heliosphere. In this paper, we present measurements of the isotopic ratios H-2/He-4, He-3/He-4, Li-6/Li-7, Be-7/(Be-9+Be-10), and B-10/B-11 in the range 0.2-1.4 GeV of kinetic energy per nucleon. The measurements are based on the data collected by the Alpha Magnetic Spectrometer, AMS-01, during the STS-91 flight in 1998 June.</P>
