Hemifacial microsomia is a common congenital craniofacial deformity involving bone and soft-tissue. Mandibular hypoplasia is the most obvious skeletal manifestation of hemifacial microsomia. In the past, complete realignment of the skeleton was preferred to soft-tissue correction, which was clearly second choice. However, in this study, simultaneous correction of bone and soft tissue deformities were equally important in treatment of hemifacial microsomia. One-stage and simultaneous bone and soft tissue reconstruction is possible and staged operations of the skeleton and soft tissue are no longer necessary, except in special cases. Even in children and adolescents, good results and normal growth potential can be achieved with simultaneous correction of bone and soft tissue.

PURPOSE: To report three cases of severe endothelial cell density loss after iris claw phakic intraocular lens (Artisan® lens) implantation. CASE SUMMARY: A 32-year-old woman underwent iris claw intraocular lens implantation in both eyes. Preoperative corneal endothelial cell count was 2,556 cells/mm² in the right eye and 2,674 cells/mm² in the left eye. After 4 years, the corneal endothelial cell count was 1,968 cells/mm² in the right eye and 1,997 cells/mm² in the left eye. A 27-year-old woman underwent iris claw intraocular lens implantation in both eyes. Preoperative corneal endothelial cell count was 3,222 cells/mm² in the right eye and 3,122 cells/mm² in the left eye. After 4 years 8 months, the corneal endothelial cell count was 2,729 cells/mm² in the right eye and 2,488 cells/mm² in the left eye. A 39-year-old woman underwent phakic intraocular lens implantation in other clinic, and the lens of left eye was removed the same day because of elevated intraocular pressure. She underwent iris claw intraocular lens implantation in the left eye. Preoperative corneal endothelial cell count was 2,500 cells/mm² in the left eye, which decreased to 1,873 cells/mm² after 8 years. Six months after intraocular lens removal and cataract surgery, her cornea endothelial cell count was 1,412 cells/mm². CONCLUSIONS: Although iris-fixed intraocular lens implantation is safe and effective for correcting myopia, at least 4 years of long-term observation for evaluating corneal endothelial cell density maybe necessary.

6.Fusobacterium nucleatum GroEL signaling via Toll-like receptor 4 in human microvascular endothelial cells.
International Journal of Oral Biology 2012;37(3):130-136
The GroEL heat-shock protein from Fusobacterium nucleatum, a periodontopathogen, activates risk factors for atherosclerosis in human microvascular endothelial cells (HMEC-1) and ApoE-/- mice. In this study, we analyzed the signaling pathways by which F. nucleatum GroEL induces the proinflammatory factors in HMEC-1 cells known to be risk factors associated with the development of atherosclerosis and identified the cellular receptor used by GroEL. The MAPK and NF-kappaB signaling pathways were found to be activated by GroEL to induce the expression of interleukin-8 (IL-8), monocyte chemoattractant protein 1 (MCP-1), intercellular adhesion molecule 1 (ICAM-1), vascular cell adhesion molecule 1 (VCAM-1), E-selectin, and tissue factor (TF). These effects were inhibited by a TLR4 knockdown. Our results thus indicate that TLR4 is a key receptor that mediates the interaction of F. nucleatum GroEL with HMEC-1 cells and subsequently induces an inflammatory response via the MAPK and NF-kappaB pathways.

The purpose of this study is to introduce a new method to reduce the donor morbidity of radial forearm free flap using ulnar forearm flap, and to evaluate its usefulness and results. 6 patients underwent radial forearm free flap designed by authors and we repaired radial forearm flap donor defect using ulnar forearm flap following ablative surgery for oropharyngeal cancers from June 1995 to February 1997. Radial forearm flap was designed just proximal to wrist crease, and its vascular pedicle was placed in the center of flap. Donor defect was repaired with V-Y fashion closure using ulnar artery axial pattern fasciocutaneous flap. Mean closing time of donor site was 30 minutes. and mean healing period of donor site was 10 days. There was no difficulty in closure. All donor sites healed completely without complication. Limitation of motion was not noticed in the wrist and forearm. We conclude that repair of radial forearm flap donor defect using ulnar forearm flap is new excellent method to prevent the prominent scar of forearm in cases of conventional skin graft for donor defect, and provide rapid healing of wound with low risk of complication

PURPOSE: The aim of this study was to examine the sensitivity and specificity of the influenza rapid antigen test, in comparison with reverse transcription polymerase chain reaction (RT-PCR), according to the time of the test from symptom onset and the clinical manifestations in the patients tested for suspected infection of the influenza A (H1N1) at a second hospital. METHODS: A total of 529 pediatric patients, aged between 6 and 12 years old, who visited the emergency department from October 1, 2009 to December 31, 2009, received the influenza rapid antigen test and RT-PCR. We examined the sensitivity and specificity of the influenza rapid antigen test in comparison with RT-PCR according to the time of the test from symptom onset (<24 hours, 24 to 48 hours, 48 to 72 hours, >72 hours) and clinical manifestations (fever, cough, rhinorrhea.nasal obstruction, sore throat, gastrointestinal symptoms, and general symptoms) in a retrospective study based on hospital charts. RESULTS: The sensitivity of the influenza rapid antigen test at elapsed times of less than 24 hours, 24 to 48 hours, and 48 to 72 hours after the onset of the symptoms was 53.9%, 61.4%, and 62.1% respectively. When the elapse time was greater than 72 hours, the sensitivity was 31.6%; thus, the sensitivity of the influenza rapid antigen test tended to decrease with elapsed time. The sensitivity of the test was 79% in patients presenting with gastrointestinal symptoms, which was the highest, but there was no statistical difference according to the clinical manifestations of the patients. CONCLUSION: Our study suggests that more accurate results might be gained when the influenza rapid antigen test is performed within 72 hours after symptom onset.
