Atlantoaxial Rotatory Fixation after Microtia Reconstruction Surgery.

Unlabelled: Nontraumatic atlantoaxial rotatory fixation after microtia reconstruction surgery is a rare complication. Intraoperative cervical hyperextension and/or excessive rotation and postoperative inflammation have been reported as causes of atlantoaxial rotatory fixation. We herein describe cases of atlantoaxial rotatory fixation after microtia reconstruction surgery.

A Herniorrhaphy Lamination Technique for the Reconstruction of Midline Abdominal Wall Defects.

The primary goal of abdominal wall reconstruction is to prevent hernia recurrence through robust and durable repair. Synthetic mesh utilization can provide sound strength but is susceptible to extrusion, infection, and intestinal fistulization. The use of autologous fasciae latae to reinforce the primary fascial reapproximation has mostly been abandoned, presumably because synthetic patches are readily available.

Costal cartilage graft with perichondrium, a possible anti-adhesive material.

Background: Adhesion occurs as a part of the wound healing process, but it sometimes compromises patients' daily activities. The authors were looking for materials and methods that could prevent adhesion, and noticed that the costal cartilage has possibility. The anti-adhesive property of the costal cartilage was examined histologically.

Assessment of a new piezoelectric transducer sensor for noninvasive cardiorespiratory monitoring of newborn infants in the NICU.

Background: Electrocardiogram (ECG) and impedance pneumography (IPG), the most widely used techniques for cardiorespiratory monitoring in the neonatal intensive care unit (NICU), have the disadvantage of causing skin damage when used for very premature newborn infants. To prevent skin damage, we designed a new piezoelectric transducer (PZT) sensor.

Objective: To assess the potential of the PZT sensor for cardiorespiratory monitoring in the NICU.

Tropoelastin regulates chemokine expression in fibroblasts in Costello syndrome.

Costello syndrome is a multiple congenital anomaly associated with growth and mental retardation, cardiac and skeletal anomalies, and a predisposition to develop neoplasia. Comprehensive expression analysis revealed remarkable up-regulation of several cytokines and chemokines including Gro family proteins, interleukin-1beta (IL-1beta), IL-8 and MCP-1 but down-regulation of extracellular matrix components including collagens and proteoglycans of skin fibroblasts derived from a Japanese Costello syndrome patient characterized by significantly reduced tropoelastin mRNA, impaired elastogenesis and enhanced cell proliferation. In contrast, decreases in these chemokines and IL-1beta expression were observed in Costello fibroblastic cell lines stably expressing the bovine tropoelastin (btEln) gene and in restored elastic fibers.
