Cardiac pseudoaneurysm is a contained rupture of the myocardium limited by pericardial adhesions or the epicardial wall. Cardiac pseudoaneurysm may cause sudden death with a mortality of 30-45% in the first year, mostly resulting from rupture. Coronal and axial T2-weighted magnetic resonance images of a 65-year-old male patient admitted with dyspnoea, coughing and chest pain, present for the last 10 days, revealed a large pseudoaneursym of the left ventricle. Coronary bypass and left ventricular restoration operation was performed...

Sinus of Valsalva aneurysms are unusual, particularly when located on the left coronary sinus. They are mainly asymptomatic, however once ruptured, they are associated with high mortality. We present hereinafter an atypical case of a 71-year-old patient with an unruptured left sinus of Valsalva aneurysm causing myocardial ischaemia due to a compressed left main coronary artery. Surgical endoaneurysmorrhaphy was performed; however, a dehiscence of the suture line between the patch and the aortic wall required additional percutaneous implantation of a vascular occluder...

Left ventricular free wall rupture is a complication following acute myocardial infarction or mitral valve replacement. We report the case of a 56-year-old female patient with idiopathic left ventricular rupture confirmed by contrast-enhanced computed tomography (CT). CT also showed no coronary artery obstruction and severe mitral annular calcification. Left ventricular rupture was successfully repaired internally with bovine pericardium. Mitral valve replacement with annular decalcification was also performed...

Spontaneous haemothorax is a subcategory of haemothorax that occurs in the absence of trauma or other causes. It is a rare emergency that can progress rapidly with massive blood loss leading to haemorrhagic shock and death. We describe a patient with massive spontaneous haemothorax caused by the disruption of an oesophageal artery from the middle segment of descending thoracic aorta. We sutured the bleeding artery in an emergency thoracotomy after the failure of interventional procedure.

BACKGROUND: Increasing number of patients with preexisting breast implants desire breast conservation therapy for breast cancer. There is paucity of comparative data on tumor margins and re-excisions in these patients. High re-excision rates up to 25% have been reported in breast conservation therapy patients; efforts to obtain cosmesis and avoid implant rupture might increase this further. We analyzed tumor margins, re-excision rates, and recurrence in previously augmented versus non-augmented patients undergoing lumpectomy for breast cancer...

PURPOSE: An epidermal cyst is one of the most common benign tumors of the skin and its major treatment method is excision. Surgical excision is treatment of choice for epidermal cysts, but the cyst wall may be ruptured during operation, especially when the cyst wall is relatively thin. The incomplete excision of the cyst sometimes occurs because of a rupture of the cyst and incomplete excision may cause recurrence. The purpose of this study is to evaluate the factors that can influence the thickness of the cyst wall of epidermal cysts...

Wayne R Cohen, Emanuel A Friedman
In the 1930s, investigators in the US, Germany and Switzerland made the first attempts to quantify the course of labor in a clinically meaningful way. They emphasized the rupture of membranes as a pivotal event governing labor progress. Attention was also placed on the total number of contractions as a guide to normality. Beginning in the 1950s, Friedman determined that changes in cervical dilatation and fetal station over time were the most useful parameters for the assessment of labor progress. He showed all normal labors had similar patterns of dilatation and descent, differing only in the durations and slopes of their component parts...

BACKGROUND: Management of ruptured arteriovenous malformations (AVMs) with a mass-producing intracerebral hematoma (ICH) represents a surgical dilemma. OBJECTIVE: To evaluate the clinical outcome and obliteration rates of microsurgical resection of AVM when performed concomitantly with evacuation of an associated space-occupying ICH. METHODS: Data of patients with AVM were collected prospectively. Cases were identified in which an AVM was resected and an associated space-occupying ICH was evacuated at the same time, and divided into "group 1," in which the surgery was performed acutely within 48 h of presentation (secondary to elevated intracranial pressure); and "group 2," in which selected patients were operated upon in the presence of a liquefying ICH in the "subacute" stage...

BACKGROUND: Approximately 17% of ruptured anterior communicating artery (ACoA) aneurysms were deemed unsuitable for coil embolization during the Barrow Ruptured Aneurysm Trial (BRAT), most commonly due to unfavorable dome-to-neck ratio or small size. OBJECTIVE: To compare patients treated by coil embolization for ruptured ACoA aneurysms during the trial to those treated after the trial to determine whether advances in endovascular techniques have allowed for effective treatment of these lesions...

BACKGROUND: Retrospective studies have suggested that aneurysm morphology is a risk factor for subarachnoid hemorrhage (SAH). OBJECTIVE: To investigate whether various morphological indices of unruptured intracranial aneurysms (UIAs) predict a future rupture. METHODS: A total of 142 patients with UIAs diagnosed between 1956 and 1978 were followed prospectively until SAH, death, or the last contact. Morphological UIA indices from standard angiographic projections were measured at baseline and adjusted in multivariable Cox proportional hazards regression analyses for established risk factors for SAH...

BACKGROUND: Flow-diverter technology has become an important stent-based embolization tool in the treatment of complex cerebrovascular pathology. We report here the experience of 4 Spanish centers with using the SILK flow-diverter (SFD) device. OBJECTIVE: To evaluate the safety and efficacy of using the SFD in the endovascular treatment of intracranial aneurysms with complex morphology. METHODS: We retrospectively examined a prospectively maintained database of patients treated with SFD devices between July 2008 and December 2013 at 1 of 4 institutions in Spain...

Soft materials may break irreversibly upon applying sufficiently large shear oscillations, a process whose physical mechanism remains largely elusive. In this work, the rupture of protein gels made of sodium caseinate under an oscillatory stress is shown to occur in an abrupt, brittle-like manner. Upon increasing the stress amplitude, the build-up of harmonic modes in the strain response can be rescaled for all gel concentrations. This rescaling yields an empirical criterion to predict the rupture point way before the samples are significantly damaged...

Early brain injury following subarachnoid hemorrhage (SAH) strongly determines the prognosis of patients suffering from an aneurysm rupture, and apoptosis is associated with early brain injury after SAH. This study was designed to explore the role of X-linked inhibitor of apoptosis (XIAP) in early brain injury following SAH. The expression of XIAP was detected using western blotting and real-time RT-PCR in an autologous blood injection model of SAH. We also studied the role of XIAP in early brain injury and detected apoptosis-related proteins...

Members of the genus Acanthamoeba are of the most common protozoa that has been isolated from a variety of environment and affect immunocompromised individuals, causing granulomatous amoebic encephalitis and skin lesions. Acanthamoeba, in immunocompetent patients, may cause a keratitis related to corneal microtrauma. These free-living amoebas easily adapt to the host environment and wield metabolic pathways such as the energetic and respiratory ones in order to maintain viability for long periods. The energetic metabolism of cysts and trophozoites remains mostly unknown...

Chronic disruption of the extensor mechanism is a devastating problem after total knee arthroplasty. Quadriceps tendon ruptures occur at an estimated 0.1% prevalence in the setting of total knee arthroplasty. Complete tears of the quadriceps tendon generally have poor results and high rates of rerupture. We present a case of a quadriceps tendon rupture after total knee arthroplasty which reruptured after initial direct repair. The patient presented to us with a chronically retracted rerupture and was subsequently reconstructed successfully with a novel extended medial gastrocnemius-soleus-calcaneus local rotational pedicle flap...

PURPOSE: Early diagnosis of attritional wear of the flexor pollicis longus (FPL) tendon is essential in preventing subsequent tendon rupture. There are currently few objective methods of assessing FPL attrition. We hypothesized that color Doppler imaging could visibly detect FPL tendon attrition, and analyzed our results. METHODS: We evaluated ultrasound imaging of the contact between the FPL tendon and a volar locking plate using the real-time B-mode and Doppler waveforms of the FPL tendon using the continuous Doppler wave mode in 40 patients who underwent fixation of the distal volar locking plate for distal radius fracture...

REVIEW
Jourdan E Triebwasser, Marjorie C Treadwell
Pulmonary hypoplasia, although rare, is associated with significant neonatal morbidity and mortality. Conditions associated with pulmonary hypoplasia include those which limit normal thoracic capacity or movement, including skeletal dysplasias and abdominal wall defects; those with mass effect, including congenital diaphragmatic hernia and pleural effusions; and those with decreased amniotic fluid, including preterm, premature rupture of membranes, and genitourinary anomalies. The ability to predict severe pulmonary hypoplasia prenatally aids in family counseling, as well as obstetric and neonatal management...

A Toffoli, M Chammas
Rupture of the collateral ligaments in the metacarpophalangeal (MCP) joint of a finger is less common than in the thumb. Literature about these lesions is sparse but the number of chronic injuries reported underlies the number of cases overlooked by physicians at the first visit. A Stener-like lesion is characterized by interposition of the extensor hood or the sagittal band between the torn collateral ligament of the MCP joint of a finger and its insertion. It was originally described as interposition of the adductor aponeurosis of the thumb...
