Samy Elian, Khaled Barakat
Closed sinus lifting is a unique technique in being simple and less invasive (Summers, Compendium 15(6):698, 1994). However, it is blind to assess the safety of sinus lining during lifting without perforation. Previously, sinus membrane was assessed endoscopically in an invasive way. We aimed to judge clinically the sinus membrane integrity after crestal elevation by a direct simple less invasive endoscopic visual assessment through the crestal osteotomy site. To confirm undetected perforation, the sinus membrane was monitored dynamically by introducing the endoscope through a trephined opening in the lateral wall of the sinus (Nkenke et al...

Barry P Levin, Stephen J Chu
The efficacy of immediate implant placement has made it an appealing treatment modality in dentistry. Over the past several decades various surgical techniques to minimize the ridge collapse and other adverse changes that occur after tooth extraction have been advocated. This case series proposes a method of soft-tissue augmentation when multiple implants are being immediately placed. The authors describe a subperiosteal tunneling technique that achieves the dual purpose of graft containment/guided bone regeneration and soft-tissue augmentation around maxillary anterior implants...

In type II sockets, the soft-tissue level is at or coronal to the cementoenamel junction, and part of the buccal plate is missing. In the esthetic zone, a patient with this type of situation often is not a good candidate for immediate implant placement until the osseous defect is repaired. Therefore, use of a conservative regenerative procedure to repair such a defective socket would be advantageous. The Cytocone procedure utilizes a nonresorbable dense polytetrafluorethylene (d-PTFE) barrier and modifies the classic "ice cream cone" technique to restore a buccal osseous defect without raising a labial flap...

Both operative and hemodynamic mechanisms have been implicated in right heart failure (RHF) following surgical left ventricular assist device (LVAD) implantation. We investigated the effects of percutaneous LVAD (pLVAD; Impella®, Abiomed) support on right ventricular (RV) load and adaptation. We reviewed all patients receiving a pLVAD for cardiogenic shock at our institution between July 2014 and April 2017, including only those with pre- and post-pLVAD invasive hemodynamic measurements. Hemodynamic data was recorded immediately prior to pLVAD implantation and up to 96 h post-implantation...

INTRODUCTION: Creating and maintaining a functional vascular access(VA) is a critical factor in the survival of a dialysis patient. However, it will not function forever, implying a creative attitude from the vascular surgeon either to maintain its functionality or built a new one wherever possible, being it autologous or synthetic. METHODS: Describe the VA history of a 59years-old male with morbid obesity and end-stage chronic kidney disease. RESULTS: His VA construction started in2012 with failed attempts in both forearms until a functional brachiocephalic artery-venous fistula(AVF) in the right upper limb was achieved, but was deemed to ligation as severe venous hypertension secondary to central venous disease related to CVC use...

Tooth replacement with a dental implant in the esthetic zone is a challenging treatment modality for the clinician. Each step of the treatment from tooth extraction to the definitive restoration should be performed meticulously to achieve a good esthetic outcome. Negative effects of the extraction can be minimized by various treatment protocols. Recent developments involving partial root retention (socket-shield technique) offer enhanced buccal tissue contour in these cases. This clinical report presents a slight modification to the socket-shield technique by preparing a thin shield and performing immediate implant placement...
