Distinct clinical picture of Cushing's syndrome in a patient with Morris' syndrome - first literature report.

Common origin of all three coronary arteries from the right sinus of Valsalva - first case study accompanied by mitral valve prolapse and vein anomaly, second case study followed by successful percutaneous coronary intervention of right coronary artery stenosis.

Congenital anomalies of the coronary arteries can be divided into two broad categories: those that alter myocardial perfusion and those that do not. In coronary anomalies not altering myocardial perfusion, the coronary arteries originate from the aorta, but their origins are in unusual positions. Although myocardial perfusion is normal, the angiographer may have trouble locating them. Patients with an anomalous left main coronary artery arising from the right sinus of Valsalva are presented. The diagnosis was made by coronary angiography, transesophageal echocardiography and multislice computed tomography (MSCT). We present two cases: the first patient with coronary abnormalities had accompanying venous anomaly of lower extremities and mitral valve prolapse as well. The second patient had a history of anterior wall myocardial infarction and angioplasty with stent implantation. The extraordinary passage of the left coronary artery between the pulmonary trunk and sternum, undetectable in coronarography, was discovered due to MSCT.

Numerical modeling of the traction process in the treatment for Pierre-Robin Sequence.

INTRODUCTION: The goal of this numerical study was to identify the results of modulated growth simulation of the mandibular bone during traction in Pierre-Robin Sequence (PRS) treatment. METHODS: Numerical simulation was conducted in the Ansys 16.2 environment. Two FEM (finite elements method) models of a newborn's mandible (a spatial and a flat model) were developed. The procedure simulated a 20-week traction period. The adopted growth measure was mandibular length increase, defined as the distance between the Co-Pog anatomic points used in cephalometric analysis. RESULTS: The simulation calculations conducted on the developed models showed that modulation had a significant influence on the pace of bone growth. In each of the analyzed cases, growth modulation resulted in an increase in pace. The largest value of increase was 6.91 mm. The modulated growth with the most beneficial load variant increased the basic value of the growth by as much as 24.6%, and growth with the least beneficial variant increased by 7.4%. CONCLUSIONS: Traction is a simple, minimally invasive and inexpensive procedure. The proposed algorithm may enable the development of a helpful forecasting tool, which could be of real use to doctors working on Pierre-Robin Sequence and other mandibular deformations in children.
