INTRODUCTION While acute appendicitis is a common surgical problem, the simultaneous occurrence of appendicitis and an infected iliac artery pseudoaneurysm is exceedingly rare. We report the successful treatment of an infected right external iliac artery pseudo aneurysm in the 1setting of acute appendicitis. PRESENTATION OF CASE The patient is an 83-year-old male who presents with severe seps...

We report the results of observations designed to investigate the spectroscopic signatures of dust clouds on the L2 brown dwarf Kelu-1. Time resolved medium resolution spectra show no significant evidence of variability in the dust sensitive TiO, CrH and FeH bandheads on the timescale of 1–24 hours. We do however report periodic variability in the psuedo-equivelent width of Hα consistent with t...

Alternation and Synchronization behaviors between the sexual communications of insects, arise as a response to the female preference to ’leaders’. As a response to this, Pholidoptera griseoptera, the dark bush cricket, has developed an interesting response model of imperfect alternating and synchronizing, or psuedo-synchronizing (P-S), for gaining the lead in a chorus of chirps. This P-S behavi...

Simulations run on sample circuits show that extremely high detection of bridging faults is possible using modifications of psuedo-exhaustive test sets. Real chips often contain bridging faults, and this research shows that stuck-at test sets are not sufficient for detecting such faults. The modified pseudo-exhaustive test sets are easy to generate and require little, or no, fault simulation. r...

This paper addresses automatic modulation classification for PSK and QAM signals under coherent and noncoherent conditions. In particular, the paper extends previous results by treating the classification of higher-state QAM signals. A maximum-likelihood algorithm is presented for coherent classification of PSK and QAM signals. We evaluate the algorithms performance for various PSK and QAM modu...

Marolt et al. have presented a very interesting case of aortoduodenal fi stula and its successful treatment1. I have read the article with great interest since it is one of the worst complications that vascular surgeon may face. We had a case of infected abscess and leakage in the thoracic aorta successfully treated with endovascular graft (TEVAR). Our approach for abdominal aorta is graft remo...

BACKGROUND The predictive factors of intima media thickness (IMT) in the HIV-infected population are still poorly understood. PATIENTS AND METHODS We studied three groups of subjects, aged 30-50 years, to find potential predictive factors of carotid and/or femoral thickening (IMT > 1 mm in at least one area): healthy controls (G1, n = 54), HIV-infected naive (G2, n = 53) and highly active ant...

AIM To investigate success of one stage exchange with retention of fixed acetabular cup. METHODS Fifteen patients treated by single stage acetabular component exchange with retention of well-fixed femoral component in infected total hip arthroplasty (THA) were retrospectively reviewed. Inclusion criteria were patients with painful chronic infected total hip. The patient had radiologically wel...

The fixation of distal femoral fractures (Vancouver type-C fractures) following a well-fixed hip arthroplasty femoral stem has become a challenging issue for orthopedic surgeons due to the inter-prosthetic biomechanical effects such as negative, positive, and torsional strain. Surgeons have applied a range of constructs to overcome these difficulties. To minimize the risk of inter-prosthetic fr...

Antibiotic cement-coated intramedullary nails maintain a locally high antibiotic concentration while contributing to bone stability. We present a case of femoral subtrochanteric fracture in a patient with an infected nonunion who was successfully treated for an infection and nonunion using an antibiotic cement-coated tibial intramedullary nail. A 79-year-old woman with a right femoral subtrocha...
