Refractory right ventricular failure (RVF) after implantation of left ventricular assist device (LVAD) is a dramatic complication. The addition of right ventricular assist device (RVAD) may improve RV recovery and lead to improve outcomes. From February 2012 to September 2014, 44 patients received a HeartMate II. These patients were retrospectively compared in two groups according to early liberal implantation of an extracorporeal membrane oxygenation (ECMO) used as a RVAD established between a femoral vein and the pulmonary artery...

Little is known about longitudinal development of the peri-implant subgingival microbiome and cytokine production as a new sulcus forms after dental implant placement. Therefore, the purpose of this observational study was to evaluate simultaneous longitudinal changes in the oral microbiome and cytokine production in the developing peri-implant sulcus compared to control natural teeth. Four and 12 weeks after implant placement and abutment connection, a dental implant and a natural tooth were sampled in 25 patients for subgingival plaque and gingival crevicular fluid (GCF [around teeth] and peri-implant crevicular fluid [PICF] around implants)...

Statement of the Problem: Despite the low failure rate of dental implants, recognition of the risk factors can enhance the predictability of failure. Purpose: The aim of this study was to evaluate the risk factors for early implant failure. Materials and Method: This retrospective cohort study was conducted on two groups of patients, the patients with a failed implant before loading and those without a failed implant. Age, gender, implant type, implant surface, implant length, bone type, type of surgery (one- or two-stage) and immediate (fresh socket) or delayed placement of implant were the variables to be assessed in this study...

Patients with ectodermal dysplasia have abnormalities of 2 or more structures that originate from the ectoderm. The oral manifestations often include the congenital absence of teeth and malformed teeth. This clinical report describes the interdisciplinary care from childhood through the definitive dental rehabilitation completed at skeletal maturation to replace the missing teeth in a patient with ectodermal dysplasia. Treatment began at 9 years of age with an implant-assisted mandibular overdenture to improve function and replace the missing mandibular teeth...

The aim of this split-mouth, randomized, double-blind, controlled clinical trial was to evaluate the influence of different insertion torque values for dental implants on bone- and angiogenesis-related marker profiles. Eighteen edentulous patients received dental implants and fixed complete-arch mandibular prostheses. The implants (n=36) were assigned randomly to two groups: reduced torque (n=18), with insertion torque <30Ncm; and conventional torque (n=18), with insertion torque ≥30Ncm. Levels of vascular endothelial growth factor (VEGF), placental growth factor, bone morphogenetic protein 9 (BMP-9), periostin, osteoprotegerin (OPG), and tartrate-resistant acid phosphatase (TRAP) in the peri-implant fluid were quantified at 7, 14, 30, and 120days after implant placement...

A tailored therapy to patient requirements by combining endovascular and surgical steps can be necessary to prolong the life of a vascular access. Stent grafts play a growing role for the therapy of dialytic access complications. Randomized multi-center trials, however, support the on-label use of stent grafts in the treatment of graft venous outflow and in-stent restenosis. The main contraindication to their use is an ongoing infection. We report two cases of new off-label application of Viabahn (Gore, flagstaff, USA) stent graft...

BACKGROUND: Massive rotator cuff tear (RCT) can result in disability and severe pain. When conservative treatment fails, surgical treatment should be considered, as various surgical options can provide relatively satisfactory results. However, choosing an optimal treatment remains controversial. A relatively new treatment for irreparable RCT is the arthroscopic implantation of a biodegradable balloon spacer into the subacromial space. Here, we examined whether placement of this balloon spacer reduces pain and improves functional outcome in patients with an irreparable RCT...

Papillon-Lefèvre syndrome (PLS) is a rare autosomal recessive disorder of keratinization associated with palmoplantar keratoderma and severe periodontitis resulting in complete edentulism in late adolescence. The pathognomonic dental features of PLS are pathologic migration, hypermobility, and exfoliation of the teeth without any signs of root resorption. It has been suggested that an effective way to treat PLS patients presenting early in the disease progression is extraction of the erupted primary dentition or hopeless permanent teeth followed by antibiotic coverage with periodontal therapy for the remaining teeth...

Clinicians very often have seen marginal bone loss around dental implants at the crest level early on after implant placement and uncovering. Early clinical publications had suggested that this bone loss occurred during the first year of loading. Thus, numerous attempts have been made to minimize or eliminate such bone loss. However, the timing and reason for this bone loss are not always apparent. The objective of this study was to review the evidence regarding marginal bone loss around dental implants from the standpoint of biologic consequences to help understand marginal bone changes around dental implants...

In aesthetic sites, the integrity of the facial bone wall dimension in the anterior maxilla is jeopardized by physiologic and structural changes postextraction. An effective regenerative protocol is key to reestablish and maintain the hard and soft tissue dimensions over time. The present prospective case series study examined the effectiveness of early implant placement with simultaneous contour augmentation through guided bone regeneration with a 2-layer composite graft in postextraction single-tooth sites over an observation period of 10 y among 20 patients...

Rib osteomyelitis is an infrequently occurring but important complication of breast implant surgery. Although prosthetic or surgical site infection (SSI) and rib osteomyelitis as separate entities are well described in the literature, only five cases of rib or sternal osteomyelitis related to implant placement have been reported globally. Historically patients who experience this complication have not demonstrated an identifiable prevalence of the traditional risk factors associated with SSI or rib osteomyelitis...

The close proximity of contraceptive implant placement to the course of the ulnar nerve can result in injury. Several factors have been implicated in this complication including: low BMI, erroneous placement of the implant, implantation over the brachial groove, and migration of the implant from its original insertion. Clinicians should familiarise themselves with the vulnerable neurovascular structures in the area and refer promptly to a specialist if any neurological symptoms develop during placement or removal of these devices...
