The normal umbilicus is a simple structure, but the intrauterine development of the umbilicus is highly complex. Neonatal umbilical mass anomalies usually represent failure of obliteration of the vitelline duct or the allantois which results in persistence of remnants, which can lead to a wide variety of disorders. In this paper, we present a case of an appendicoumbilical fistula in a neonate a...

Medical practice and life sciences take full advantage of progress in engineering disciplines, in particular the computer assisted placement technique in hip surgery. This paper describes the three dimensional model reconstruction of human femur from MRI images. The developed program enables to obtain digital shape of 3D femur recognized by all CAD software and allows an accurate placement of t...

Bioengineering reasons for increased wear and failure of metal-on-metal (MoM) bearings in hip prostheses have been described. Low wear occurs in MoM hips when the centre of the femoral head is concentric with the centre of the acetabular component and the implants are correctly positioned. Translational or rotational malpositioning of the components can lead to the contact-patch of the femoral ...

Persistent left superior vena cava is a congenital vascular anomaly, which is possibly arrhythmogenic and thrombogenic, rarely complicated with coronary sinus atresia. We treated a 42-year-old male with Hodgkin's lymphoma requiring central venous catheter placement for intensive chemotherapy. Persistent left superior vena cava was revealed after the insertion of the central venous catheter by t...

Cephalic malposition of lower lateral cartilage (CMLLC) is one of the most common objects of aesthetic and functional rhinoplasty. Constantian wrote in his article that 68% of his primary rhinoplasty cases had lateral crural malpositioning.1 To diagnose CMLLC the surgeon has to observe several parameters that were described by Sheen: malposition is “any displacement of the lateral crura from th...

We describe a rare intraaortic balloon pump (IABP) vascular complication as a result of malpositioning of the IABP. A 61-year-old man with unstable angina underwent emergency coronary artery bypass grafting soon after the insertion of an IABP. Postoperative hemodynamics were stable, but acute hepatic dysfunction occurred on the second postoperative day. Doppler echography revealed the absence o...

original article   one type of electromagnetic fields, based on frequency range, is extremely low frequency (elf) fields. there are lots of reports about measuring elf-magnetic field (mf) in substations, power plants, cities and etc. this study aimed to compare the difference between measurement of three-axis and single-axis probe mf meters. elf-mf was measured by tes-1394 mf tester (three-axis...

The malpositioning of a pacemaker lead is an uncommon and under-reported complication of pacemaker/Automated Implantable Cardioverter-Defibrillator (AICD) placement. It can be associated with complications such as pericardial effusions and tamponade. We describe a case of an elderly woman who developed cardiac tamponade after inadvertent placement of a permanent pacing lead in the left ventricl...

We conducted a contemporary review covering advances and trends in primary and functional rhinoplasty as published during the past decade. Specifically, we reviewed studies supporting the evidence for functional rhinoplasty, nasal valve surgery, and septal reconstruction. In addition, key articles discussing cephalic malpositioning of the lower lateral cartilages and tip contouring are reviewed...

Bilateral carpal tunnel syndrome should prompt consideration of systemic diseases that infiltrate or impinge both canals (eg, rheumatoid arthritis, acromegaly, hypothyroidism, amyloidosis), although it is most frequently explained by a bilateral repetitive stress (eg, workplace typing). The development of upper extremity weakness suggests that an alternative condition such as cervical myelopath...
