Iatrogenic superficial external pudendal artery pseudoaneurysm: Treatment with doppler us-guided compression
Pseudoaneurysms rarely occur as a serious complication following incomplete hemostasis of an arterial puncture site. As a result of the increase in diagnostic and therapeutic angiography, the frequency of iatrogenic pseudoaneurysm has increased as well. Iatrogenic pseudoaneurysms associated with angiographic catheterization occur most commonly in the common femoral artery. Here we report a case of iatrogenic superficial external pudendal artery (SEPA) pseudoaneurysm following cardiac catheterization, which was diagnosed with Doppler ultrasound (US) and multidetector computed tomographic angiography (MDCTA) before Doppler US-guided compression therapy. To the best of our knowledge, iatrogenic SEPA pseudoaneurysm, which is an unusual vessel location for pseudoaneurysm occurrence, has not been reported in the literature. In patients in whom anticoagulant-thrombolytic therapy or therapeutic catheterization with larger sized sheath is planned, determination of the precise localization of arterial puncture site is important for the prevention of iatrogenic pseudoaneurysm development. Arterial puncture guided with Doppler US might reduce complications. When suspected, MDCTA is useful in the diagnosis and demonstration of iatrogenic pseudoaneurysms. Treatment of US-guided compression should be the first choice for iatrogenic pseudoaneurysms. Interventional radiologists and cardiologists should have enough experience about the catheterization complications and their treatment in order to decrease the morbidity and mortality related to the intervention

Comparison between Capsule Endoscopy and Magnetic Resonance Enterography for the Detection of Polyps of the Small Intestine in Patients with Familial Adenomatous Polyposis
Objective. The objective of this study was to assess the utility of magnetic resonance enterography (MRE) compared with capsule endoscopy (CE) for the detection of small-bowel polyps in patients with familial adenomatous polyposis (FAP). Methods. Patients underwent MRE and CE. The polyps were classified according to size of polyp: <5 mm (small size), 5–10 mm (medium size), or >10 mm (large size). The location (jejunum or ileum) and the number of polyps (1–5, 6–20, >20) detected by CE were also assessed. MRE findings were compared with the results of CE. Results. Small-bowel polyps, were detected by CE in 4 of the 6 (66%) patients. Three patients had small-sized polyps and one patient had medium-sized polyps. CE detected polyps in four patients that, were not shown on MRE. Desmoid tumors were detected on anterior abdominal wall by MRE. Conclusion. In patients with FAP, CE can detect small-sized polyps in the small intestine not seen with MRE whereas MRE yields additional extraintestinal information
A comparative study on q-deformed fermion oscillators
In this paper, the algebras, representations, and thermostatistics of four
types of fermionic q-oscillator models, called fermionic Newton (FN),
Chaichian-Kulish-Ng (CKN), Parthasarathy-Viswanathan-Chaichian (PVC),
Viswanathan-Parthasarathy-Jagannathan-Chaichian (VPJC), are discussed.
Similarities and differences among the properties of these models are revealed.
Particular emphasis is given to the VPJC-oscillators model so that its Fock
space representation is analyzed in detail. Possible physical applications of
these models are concisely pointed out.Comment: 32 pages, 2 figures, to appear in Int. J. Theor. Phys. (IJTP
Large enhancement of radiative strength for soft transisitons in the quasicontinuum
Radiative strength functions (RSFs) for the 56,57-Fe nuclei below the
separation energy are obtained from the 57-Fe(3-He,alpha gamma)56-Fe and
57-Fe(3-He,3-He' gamma)57-Fe reactions, respectively. An enhancement of more
than a factor of ten over common theoretical models of the soft (E_gamma ~< 2
MeV) RSF for transitions in the quasicontinuum (several MeV above the yrast
line) is observed. Two-step cascade intensities with soft primary transitions
from the 56-Fe(n,2gamma)57-Fe reaction confirm the enhancement.Comment: 4 pages including 3 figure
Level density of Fe and low-energy enhancement of -strength function
The MnFe differential cross section is measured at
MeV\@. The Fe level density obtained from neutron evaporation spectra is
compared to the level density extracted from the
FeHe,Fe reaction by the Oslo-type technique.
Good agreement is found between the level densities determined by the two
methods. With the level density function obtained from the neutron evaporation
spectra, the Fe -strength function is also determined from the
first-generation matrix of the Oslo experiment. The good agreement
between the past and present results for the -strength function
supports the validity of both methods and is consistent with the low-energy
enhancement of the strength below MeV first discovered by the
Oslo method in iron and molybdenum isotopes.Comment: 7 pages, 5 figure
Thermodynamic Properties of Fe
Nuclear level densities for Fe have been extracted from the primary
-ray spectra using (He,He) and (He,) reactions. Nuclear thermodynamic properties for Fe and
Fe are investigated using the experimental level densities. These
properties include entropy, Helmholtz free energy, caloric curves, chemical
potential, and heat capacity. In particular, the breaking of Cooper pairs and
single-quasiparticle entropy are discussed and shown to be important concepts
for describing nuclear level density. Microscopic model calculations are
performed for level densities of Fe. The experimental and calculated
level densities are compared. The average number of broken Cooper pairs and the
parity distribution are extracted as a function of excitation energy for
Fe from the model calculations.Comment: 24 pages, 11 figure
