Here, we report the efficacy of the suture bridge technique for treating insertional Achilles tendinosis in an obese and athletic patient. A 48-year-old man presented to our department with a 6-month history of left posterior heel pain. The patient was an athlete (triathlon) and appeared obese (height: 197 cm, body weight: 120 kg, body mass index: 30.9). A diagnosis of insertional Achilles tendinosis was made. Because 6 months of conservative treatments had failed, we performed open resection of the calcaneal exostosis and Haglund's deformity along with debridement of the degenerative tissue of the tendon...

Mechanical damage to middle ear components in blast exposure directly causes hearing loss, and the rupture of the tympanic membrane (TM) is the most frequent injury of the ear. However, it is unclear how the severity of injury graded by different patterns of TM rupture is related to the overpressure waveforms induced by blast waves. In the present study, the relationship between the TM rupture threshold and the impulse or overpressure waveform has been investigated in chinchillas. Two groups of animals were exposed to blast overpressure simulated in our lab under two conditions: open field and shielded with a stainless steel cup covering the animal head...

INTRODUCTION: Implant neck fracture involving a non-modular femoral stem is rare in primary total hip arthroplasty (THA). Occasional cases have been reported following laser etching of the Corail(tm) stem, but risk factors have not been precisely determined. We therefore performed a retrospective study on a series of Corail(tm) stems with laser neck etching, in order to: (1) determine the exact implant neck fracture rate at 10 years, and (2) identify associated risk factors. HYPOTHESIS: Laser etching increases the rate of implant neck fracture...

BACKGROUND: Acellular dermal matrices (ADM) such as Strattice(TM) are increasingly used in UK during implant-based reconstruction. However, there are mixed opinions regarding the compatibility of radiotherapy treatment in pre- and post-reconstructed breasts. The aims of this study are to audit the rates of radiation induced complications in patients who underwent breast reconstruction using Strattice(TM) and establish whether there is an association between timing of radiotherapy and complication rates...

After decades of indolent progression, atherosclerosis may cause unheralded events, such as myocardial infarction, acute coronary syndrome and stroke due to sudden rupture of atherosclerotic plaques, and pharmacologically modulating plaque stability would reduce the risk of cardiovascular diseases. Endoplasmic reticulum stress (ERS) is responsible for the vulnerability of plaques. However, the underlying mechanism has not been fully elucidated. In this work, ApoE(-/-) mice underwent perivascular carotid collar placement surgeries or sham operations were given higher (3...

Lysophosphatidic acid (LPA) receptor 1 (LPA1) is a member of the G protein-coupled receptors mediating the biological response to LPA species. Lack of detailed mechanism underlying LPA/LPA1 interaction has hampered the development of specific antagonists. Here, novel N-terminal Lys39 has been identified as a key residue during LPA-type agonist binding and LPA1 activation. Analysis of the molecular dynamics (MD) trajectories showed that LPA-type agonist but not VPC-32183 (antagonist) evolved structures with classical GPCR activation signatures such as reduced cytoplasmic transmembrane (TM) 3/TM6 dynamic network, ruptured ionic lock, and formation of a continuous and highly ordered internal water pathway was also observed...

To describe our initial experience and early outcomes with distal placement of the Neuron 6F guiding catheter through coiled ICA for aneurysmal EVT. We examined the utility of the Neuronf 70 6F guiding catheter for the embolization procedure in such cases, fourteen cases of aneurysm with coiling of the parent ICA are presented via traditional guiding catheters. With the support of 8F ENVOY guiding catheter as a shuttle sheath, the Neuron(TM) 70 6F guiding catheter was successfully placed through coiled extracranial ICA, so the mirocatheter could be delivered to a more strategic position for embolization of the aneurysm...

Rupture of the abdominal aortic aneurysm (AAA) occurs when the local wall stress exceeds the local wall strength. Knowledge of AAA wall mechanics plays a fundamental role in the development and advancement of AAA rupture risk assessment tools. Therefore, the aim of this study is to evaluate the biaxial mechanical properties of AAA tissue. Multiple biaxial test protocols were performed on AAA samples harvested from 28 patients undergoing open surgical repair. Both the Tangential Modulus (TM) and stretch ratio (λ) were recorded and compared in both the circumferential (ϴ) and longitudinal (L) directions at physiologically relevant stress levels, the influence of patient specific factors such as sex, age AAA diameter and status were examined...

DPPC liposomes ranging from 90 nm to 160 nm in diameter were prepared and used for studies of the formation of supported lipid membranes on silica (SiO2) at temperatures below and above the gel to liquid-crystalline phase transition temperature (Tm = 41 °C), and by applying temperature gradients through Tm. The main method was the quartz crystal microbalance with dissipation (QCM-D) technique. It was found that liposomes smaller than 100 nm spontaneously rupture on the silica surface when deposited at a temperature above Tm and at a critical surface coverage, following a well-established pathway...

BACKGROUND: Preterm birth is the most common cause of neonatal morbidity and mortality. Postponing delivery for 48 hours with tocolytics to allow for maternal steroid administration and antenatal transportation to a centre with neonatal intensive care unit facilities is the standard treatment for women with threatening preterm delivery in most centres. However, there is controversy as to which tocolytic agent is the drug of first choice. Previous trials have focused on tocolytic efficacy and side effects, and are probably underpowered to detect clinically meaningfull differences in neonatal outcome...

Prehospital acute blunt thoracic trauma care remains difficult. Among then, diagnosis of atelectasis with ultrasound remains rare and unusual. We report the case of a worker who had a sharp chest pain currently after using a jackhammer. First clinical examination suspected a left tension pneumothorax but ruled out by sliding sign in left hemithorax ultrasound (US) examination. The right upper thoracic scan showed a well-defined lung point, a "hepatization" appearance with static air bronchograms, a diaphragm elevation and a dextrocardia in B mode, and a pseudobarcode with no lung pulse in Time Motion (TM) mode...
