Bone Augmentation of Peri-Implant Dehiscence Defects Using Multilaminated Small Intestinal Submucosa as a Barrier Membrane: An Experimental Study in Dogs.

Bone Augmentation of Peri-Implant Dehiscence Defects Using Multilaminated Small Intestinal Submucosa as a Barrier Membrane: An Experimental Study in Dogs. Biomed Res Int. 2019;2019:8962730 Authors: Wang S, Wu W, Liu Y, Wang X, Tang L, You P, Han J, Li B, Zhang Y, Wang M Abstract Objective: The aim of the study is to evaluate the effects of multilaminated small intestinal submucosa (mSIS) combined with bone substitute material to repair peri-implant defects during guided bone regeneration procedures. Methods: Twelve implants were placed in bilateral lower premolars of three beagle dogs, and a peri-implant buccal bone defect (3 mm width and 4 mm height) was created at each implant site. A total of 12 sites were filled with a particulate bone substitute material and then randomly divided into three treatment groups: covered by mSIS membrane (mSIS group), covered by collagen membrane (BG group), and no treatment (control group), each group of four sites. After 12 weeks of healing, all of the animals were euthanized and dissected blocks were obtained for micro-computed tomography (micro-CT) and histological analyses. Results: Micro-CT results revealed similar horizontal width of augmented tissue and new bone formation between mSIS and BG groups (P 0.05). All of these parameters were significantly different from those in the control group (P

The J.P. Morgan Healthcare conference runs every year in San Francisco, a big draw for the biotech industry, and many organizations take the opportunity to host events at the same time. Among these, the SENS Research Foundation has for the past few years hosted a pitch day in which biotech companies in the longevity industry, largely startups, present to that portion of the Bay Area investor community interested in funding the treatment of aging as a medical condition. I was there to present on progress at Repair Biotechnologies, and took some notes on the other companies as they talked about their work. Kimera Labs ...

ConclusionMorgagni hernia is a rare form of congenital diaphragmatic hernia. It is commonly found either in the first few hours of life or in the antenatal period. It is less common in adults and is usually diagnosed accidentally in asymptomatic patients. Symptomatic adult cases are extremely rare. Respiratory symptoms are the most common presenting symptoms. The primary management for both symptomatic and incidentally discovered asymptomatic cases of Morgagni hernia is surgical correction. Various thoracic and abdominal surgical approaches have been described without a clear consensus on preference for operative repair technique.

AbstractA 58 ‐year‐old woman was referred to our hospital with progressively increasing breathlessness. She reported a history of bioprosthetic valve implantation for tricuspid valve replacement and direct closure of an atrial septal defect for Ebstein's anomaly, 31 years before presentation. Transthoracic e chocardiography revealed prosthetic valve failure, an enlarged coronary sinus, and severe mitral regurgitation. Computed tomography revealed a giant coronary sinus with thrombosis and persistent left superior vena cava. She underwent successful mitral and tricuspid valve replacement; however, severe hemodynamic det...

Conclusion: Surgical reconstruction is a common treatment for ACL injury. Computed tomography scanning of pediatric tissue clearly defines the location of the ACL and MCL with respect to the femoral and tibial physes, and may guide surgeons for physeal respecting procedures. Clinical Relevance: In addition to ACL reconstruction, recent basic science and clinical research suggest that ACL repair may be more commonly performed in the future. MCL repair and reconstruction is also occasionally required in skeletally immature patients. This information may be useful to help surgeons avoid or minimize physeal injury during ...

Conclusions: Using the "aorta-clamp" technique with continual bilateral antegrade cerebral perfusion, total arch replacement combined with an elephant trunk implantation can be performed under five minutes of mild (30 °C) HCA. Our data suggest that this technique for the surgical repair of AAAD is a safe, feasible and effective surgical approach with satisfactory early outcomes. PMID: 31903261 [PubMed]

ConclusionInterarterial segment stenting appears feasible and safe. More important population and longer follow-up are needed to include this approach in a future management algorithm for patients with ANOCOR.

ConclusionSurgical correction in AAOCA is mandatory for symptomatic and asymptomatic patients with evidence of myocardial ischemia under stress or restricted coronary artery segment. Surgical unroofing remains the gold standard but is not appropriated in all particular forms: alternative techniques should be considered in the latter. Surgical results are promising.

CONCLUSIONS: The current body of evidence suggests that intra-operative CT is superior to completion angiography at detecting clinically important EVAR complications and incurs a lower total radiation dose with no added risk of contrast-induced renal impairment. Further research directly comparing the two modalities in the same cohort is required to determine sensitivity for individual complications. PMID: 31904305 [PubMed - as supplied by publisher]

Abstract OBJECTIVE: The aim of this study was to evaluate aortic remodelling and associated complications in patients treated by thoracic endovascular aneurysm repair (TEVAR) for blunt traumatic aortic injuries (BTAI). METHODS: This was a retrospective, observational, multicentre study. Remodelling was considered as aortic diameter variations of>2 mm and distal graft and aortic axis angle modification measured by computed tomography angiography (CTA). The predefined levels of measurement were the proximal end of the graft (D1: landing in zone [LZ] 2; D2: LZ 3); distal end (D3); and control measurement...
