BACKGROUND: Total knee arthroplasty is associated with blood loss during the intervention and may require allogenic blood transfusion. Treatments such as tranexamic acid and fibrin sealants improved the bleeding control in several clinical trials, but the hemorrhage associated with the intervention is still significant. Thus far, very few studies have evaluated hemostatic treatments in animal models of total knee arthroplasty. This work describes a sheep model of bleeding associated with total knee arthroplasty and investigates a new class of hemostatic treatment based on recombinant tissue factor...

Differentiation between accessory sutures and fractures in the skull of an infant can be difficult. Apart from the regular sutures there is a multitude of variations that may be mistaken for a fracture line. Such variations include for instance the intraparietal suture between the two ossification centers of the parietal bone or the mendosal suture between the supraoccipital and interparietal bone of the occipital squama. The presented case refers to an approximately 20-month-old female child. During autopsy, a discontinuity in the right paramedian posterior cranial fossa parallel to the internal occipital crest with connection to the foramen magnum was observed...

The aim of the study was to define and solve main problems in nasal defects reconstruction procedures planning. Fifty-two patients with nasal defects treated in Central Research Institute of Dentistry and Maxillofacial Surgery in 2010-2015 were included in the study. In 28 cases the defects were reconstructed by means of paramedial forehead flap. The authors highlight typical procedure pitfalls mainly associated with the planning stage. The study results prove paramedical forehead flap to be the most useful tool for subtotal and total nasal defects reconstruction but meticulous procedure planning is a must for success...

PURPOSE: Paramedial mandibulotomy facilitates access for the resection of tumors in the oral and oropharyngeal space; however, severe complications related to surgical techniques and radiotherapy have been reported for this procedure. This study evaluated whether preservation of the periosteum during a mandibulotomy would decrease postoperative complications owing to the increased healing capacity provided by preserving more tissue. MATERIALS AND METHODS: Patients who underwent mandibulotomy for surgical tumor ablation from 2007 through 2012 were included in a retrospective controlled cohort study...

BACKGROUND AND OBJECTIVE: Cervical spondylotic amyotrophy (CSA) is a relatively rare disorder. This study was conducted to elucidate the prognosis of proximal-type CSA after anterior decompressive surgery by evaluating clinical factors and imaging findings. METHODS: Anterior decompressive surgery was performed in 40 patients with proximal-type CSA between March 2000 and December 2011. Patients were classified into 2 categories based on axial T2-weighted magnetic resonance imaging (MRI) findings: "nerve root compression (NRC)", with nerve root compressed at the intervertebral foramen, and "spinal cord compression (SCC)" with spinal cord compressed at the medial or paramedial site of spinal canal...

The larvsal trunk wall of Sabatinca chalcophanes (Meyrick, 1885), representing the "sabatincoid morphotype," is described (brightfield and polarization microscopies, scanning and transmission electron microscopies). Eight sensillum types are identified, including four previously undescribed subventral and ventral kinds. The cuticle is nonsolid, the exocuticle being chambered in a honeycomb-like fashion with chamber walls apparently secreted along epidermal cells boundaries. The chamber contents open to the exterior via minute pores in the chamber roofs...

Sirenomelia is the most severe malformation complex affecting the human caudal pole, although its etiology is unclear, a primary defect of blastogenesis has been proposed. Studies consider sirenomelia as the most severe form of caudal dysgenesis, VACTERL association, or axial mesodermal dysplasia, although others still support the idea of a different pathologic entity. We report the prenatal, clinical, and pathologic features of a fetus with cleft lip and palate, microtia, cardiac, renal and intestinal malformations, radial aplasia, and sirenomelia...

OBJECTIVES: The superficial layer of deep cervical fascia represents a valuable material for the reconstruction of defects secondary to partial vertical laryngeal resections. However, there are drawbacks to the use of this flap, which include possible weakness and subsequent instability of the laryngeal wall. METHODS: To overcome this problem, we included platysma along with the superficial layer of deep cervical fascia to form a composite soft tissue flap that will meet all reconstructive needs following partial vertical laryngeal resection...

OBJECTIVES: To assess a surgical technique and the postoperative outcomes of a consecutive series of 22 patients treated for degenerative lumbar spondylolisthesis (DLS) through a minimally invasive unilateral approach associating interbody fusion and percutaneous osteosynthesis. PATIENTS AND METHODS: Twenty-two patients were included in this study, with a mean age of 60 years (range, 35-77 years). All had low-grade single-level DLS. In all cases, the technique included a posterior unilateral paramedial approach through a tubular retractor that decompressed the vertebral canal and transforaminal intervertebral cage arthrodesis...

Gross dissection for demonstrating anatomy of the human pelvis has traditionally involved one of two approaches, each with advantages and disadvantages. Classic hemisection in the median plane through the pelvic ring transects the visceral organs but maintains two symmetric pelvic halves. An alternative paramedial transection compromises one side of the bony pelvis but leaves the internal organs intact. The authors propose a modified technique that combines advantages of both classical dissections. This novel approach involves dividing the pubic symphysis and sacrum in the median plane after shifting all internal organs to one side...

The gastric bypass is a good option in the therapy of morbid obesity. Nevertheless, it must be considered the rare condition as occurred in a patient with previous abdominal surgery with Situs Inversus Totalis. A 24 year-old male patient with body mass index of 40 Kg/ m(2), multiple dietary failures, and arterial hypertension as co-morbidities, with a anterior paramedial right incision due to a previous appendicectomy (8 years ago).With a indication for bariatric surgery, was performed Roux-en-Y gastric bypass by laparoscopic procedure, with previous planning of Situs Inversus Totalis...

PURPOSE: The use of bioabsorbable self-reinforced poly(L/DL)lactide 70/30 (SR-PLDLA) miniplates and screws could offer many benefits compared with conventional metallic devices for fixation of access osteotomies in oral cancer surgery. The material neither interferes with imaging nor with postoperative radiotherapy. The plates and screws do not need to be removed. The number of operations can be diminished and rehabilitation with dental implants shortened. The purpose of the present study was to report our experience with bioabsorbable osteosynthesis in the fixation of access osteotomies of the mandible...

Ocular tilt reaction (OTR) includes skew deviation, eye torsion and head tilt. It is usually accompanied by a tilt in the subjective visual vertical. OTR seems to reflect an otolithic dysfunction. This case report shows an OTR of central origin as a result of simultaneous paramedial thalamic and mesencephalon rostral infarcts.
