This study was conducted to determine the prevalence of PE in patients with V/Q scans interpreted as representing a very low probability (VLP) of PE (1-3 small segmental perfusion defects with a normal chest radiograph). An analysis of the entire data set obtained during the PIOPED study was performed. Of the total of 1,359 patients in whom the presence or absence of PE was confirmed, 80 ...

A 17-year-old female presented with dyspnea, chest pain, and a very large cyst occupying the entire right hemithorax Figure 1(A, B). The patient is under full cyst extending to membrane Figure 2 (A, B).

Background: Metabolic bone diseases (MBD), including rickets and osteopenia, are important neonatal complications among preterm infants. This study aimed to determine the prevalence and risk factors of MBD in neonates with very low birth weight (VLBW). Methods: This prospective study was conducted on VLBW infants from January 2012 to July 2013. Inclusion criteria were birth weight of ≤1500 g a...

  Human hydatid cyst is a wide spread disease. It is an endemic disease in Iran. Hydatid cyst is extremely rare in the female reproductive organs. This is a case report of ovarian hydatid cyst in a 42-year-old woman. She presented with feeling of enlargement of abdomen and abdominal pain.

We show that the algorithms which behave well on average may have difficulty only for highly structured, non-random inputs, except in a finite number of cases. The formal framework is provided by the theory of Kolmogorov complexity. An experimental verification is done for graph S-colorability with Brhlaz’s algorithm.
