BACKGROUND Saline breast implant rupture remains problematic after implantation. Company reports and previous studies implicate the valve as a common site of implant failure. This study evaluates the rupture rate of the Mentor posterior valve compared with the anterior valve in breast augmentation and reconstruction. METHODS This is a retrospective analysis of consecutive breast implantations...

OBJECTIVE To determine the prevalence of uterine rupture worldwide. DESIGN Systematic review of all available data since 1990. SETTING Community-based and facility-based reports from urban and rural studies worldwide. Sample Eighty-three reports of uterine rupture rates are included in the systematic review. Most are facility based using cross-sectional study designs. METHODS Following a ...

OBJECTIVE In this study, the incidence, etiologies, and management with respect to clinical outcome of patients with iatrogenic aneurysmal rupture during attempted coil embolization of intracranial aneurysms are reviewed. METHODS A retrospective analysis was conducted of 274 patients with intracranial aneurysms treated with Guglielmi detachable coils over a 6-year period from 1994 to 2000. Pa...

case presentation we report a case of anaphylactic shock during surgery of pulmonary hydatid cyst in a 42 year old woman and its management. conclusions during the surgery of hydatid cyst, any hemodynamic instability should raise the suspension of anaphylaxis and early resuscitation should be instituted. introduction hydatid cyst is a parasitic disease caused by a tapeworm echinococcusgranulosu...

OBJECTIVE The purpose of this study was to determine the cause and frequency of aneurysm rupture after endovascular aneurysm repair. METHODS We reviewed each patient who sustained aneurysm rupture among all patients enrolled for endovascular aortic aneurysm repair in phases I, II, and III of the US AneuRx Multicenter Clinical Trial from June 1996 through October 1999. RESULTS A total of 106...

We have determined a source rupture model for the 1992 Landers earthquake (Mw 7.2) compatible with multiple data sets, spanning a frequency range from zero to 0.5 Hz. Geodetic survey displacements, near-field and regional strong motions, broadband teleseismic waveforms, and surface offset measurements have been used explicitly to constrain both the spatial and temporal slip variations along the...

We use the 2D finite element method to determine how geometrical parameters determine whether rupture will propagate across a linked stepover in a strike-slip fault. The end segments of the fault system are aligned in the direction of maximum shear, and the length and angle of the linking segment are allowed to vary. We observe that ruptures propagate through extensional stepovers with steeper ...

BACKGROUND Recent reports of the risk of morbidity due to uterine rupture are thought to have contributed in some countries to a decrease in the number of women attempting a vaginal birth after caesarean section. The aims of this study were to estimate the incidence of true uterine rupture in the UK and to investigate and quantify the associated risk factors and outcomes, on the basis of intend...

Background: Ventricular septal rupture is a rare but fatal mechanical complication of acute myocardial infarction. Although the incidence has decreased, the mortality rate from ventricular septal rupture has remained extremely high. Objectives: The aim of this study was to assess the patient with acute myocardial infarction complicating with ventricular septal rupture and to identify the risk f...

Anterior cruciate ligament (ACL) rupture is a common condition that can be devastating and life changing, particularly in young adults. A non-contact mechanism is typical. Second ACL ruptures through rupture of the contralateral ACL or rupture of a graft repair is also common. Risk of rupture is increased in females. ACL rupture is also common in dogs. Disease prevalence exceeds 5% in several d...
