Although avulsion fractures of the calcaneal tuberosity are rare injuries, these can be a challenging problem with frequent complications, such as loss of reduction and soft tissue problem. Anatomical reduction and internal fixation are indicated to avoid these pitfalls and to restore function of the triceps surae. However, the best fixation device and operative technique are still controversial. A case that achieved satisfactory clinical outcome through a reattachment technique using the suture bridge augmentation for Achilles tendon avulsion fracture with osteoporotic bony fragment is presented...

STUDY DESIGN: Randomized complete block animal spinal implant infection model with internal control. OBJECTIVE: To develop a spinal implant animal infection model to simulate postoperative gram-negative wound infection. SUMMARY OF BACKGROUND DATA: Implant-associated surgical site infections (SSI) remain a dreaded complication of spinal surgery. Currently, over 30% of all spine SSIs are secondary to gram-negative bacteria. Traditional animal models have utilized gram-positive inoculums to simulate postoperative infection, but there exists no model in the literature for gram-negative infection in the setting of spinal instrumentation...

X-linked hypophosphataemic rickets (XLHR) is a genetic disorder resulting from a genetic mutation in the PHEX gene. This may cause ossification of soft tissue structures risking spinal cord compression. We present the first known case of cervical dural calcification secondary to XLHR to cause myelopathic symptoms due to cord compression.

BACKGROUND: Zirconia abutments are frequently used for implant-supported single crowns. Even though demonstrating esthetic benefits compared to metal abutments, zirconia abutments lead to an increased brightness of the peri-implant mucosa compared to natural teeth and are not ideal from an esthetic point of view. PURPOSE: To test whether or not a fluorescent hybrid zirconia abutment offers superior esthetics compared to a non-fluorescent one-piece zirconia abutment based on spectrophotometric analysis...

OBJECTIVES: Fetal soft tissue can be assessed by using fractional limb volume as a proxy for in utero nutritional status. We investigated automated fractional limb volume for rapid estimate fetal weight assessment. METHODS: Pregnant women were prospectively scanned for 2- and 3-dimensional fetal biometric measurements within 4 days of delivery. Performance of birth weight prediction models was compared: (1) Hadlock (Am J Obstet Gynecol 1985; 151:333-337; biparietal diameter, abdominal circumference, and femur diaphysis length); and (2) Lee (Ultrasound Obstet Gynecol 2009; 34:556-565; biparietal diameter, abdominal circumference, and automated fractional limb volume)...

BACKGROUND: The current staging system for pancreatic ductal adenocarcinoma (PDAC) includes information about size and local extension of the primary tumor (T stage). The value of incorporating any local tumor extension into pancreatic staging systems has been questioned because it often is difficult to evaluate tumor extension to the peri-pancreatic soft tissues and because most carcinomas of the head of the pancreas infiltrate the intra-pancreatic common bile duct. This study sought to evaluate the prognostic implications of having PDAC with local tumor extension...

INTRODUCTION: Many surgical techniques have been described for the treatment of TMJ ankylosis, but no strategy has been uniformly agreed upon underscoring the difficulty of the problem. Despite new guidelines and updated methods, treating patients with TMJ Ankylosis remains a challenge as the incidence of recurrence after treatment is soaring. This study exemplifies our experience in using an unsullied method to treat TMJ Ankylosis to restore the structure of TMJ in conjunction with convalescing secondary maxillofacial deformity...

OBJECTIVES: Approximately 1 % of all malignant solid tumours of the head and neck area are metastases from primary tumours beneath the clavicles. The aim of this study was to analyse the distribution of primary tumours since meta-analyses might have been biased due to the usually extraordinary character of case reports. MATERIALS AND METHODS: All patient files from 1970 to 2012 from the Oral and Maxillofacial Surgery unit at a University Hospital were analysed regarding the existence of metastases to the head and neck area from distant primaries...

Staphylococcus aureus is a major cause of skin and soft-tissue infection. The bacterium expresses four major proteases emerging as virulence factors; aureolysin (Aur), V8 protease (SspA), staphopain A (ScpA), and staphopain B (SspB). We hypothesized that human galectin-3, a β-galactoside-binding lectin involved in immune regulation and antimicrobial defense, is a target for these proteases, and that proteolysis of galectin-3 is a novel immune evasion mechanism. Indeed, supernatants from laboratory strains and clinical isolates of S...

The pericytic (perivascular myoid cell) family of tumors is a distinctive group of mesenchymal neoplasms encountered in superficial sites and only rarely seen in viscera. The pericytic family subtends a spectrum of lesions, namely, glomus tumors and variants; myopericytoma, including myofibroma; and angioleiomyoma. In light of the contemporary classification of pericytic lesions, we identified and reviewed 17 cases of renal pericytic tumors from the files of 6 referral centers. These tumors presented over an age range of 17 to 76years (mean 46...
