Use of split thickness plantar skin grafts in the treatment of hyperpigmented skin-grafted fingers and palms in previously burned patients.

Palmar and finger burns are often seen in children, and are usually as a result of contact burns. Some patients with deep hand burns are treated with full-thickness or split-thickness skin grafts. Skin graft is commonly used for hand reconstruction.

Glomus tumour within digital nerve: a case report.

Glomus tumour is a rare soft-tissue tumour developing in the hand. As it presents classic symptoms, it is most often diagnosed clinically. Preoperative radiological studies have been used to both determine exact location and size of the tumour as well as distinguish glomus tumour from other benign tumours of neural or non-neural origin.

Recurrent dissociation of the tibial insert after mini-subvastus posterior-stabilized total knee arthroplasty: a case report.

We report here on an unusual case of recurrent dissociation of a polyethylene tibial insert from its metal baseplate after high-flex posterior-stabilized (PS) Genesis II total knee arthroplasty with using the mini-subvastus approach. After the 1st episode of dissociation, which had happened 1 month after the primary surgery, we changed the tibial insert and found damages on the dovetails and the post of the retrieved insert. Unfortunately, the patient suffered the same dissociation 1 month after the tibial insert was changed.

Spinal cord injury in cervical spinal stenosis by minor trauma.

Background: The size of the spinal canal is a factor that contributes to the neurologic deficits associated with cervical OPLL and CSM. We investigate the development of neurologic deterioration after minor trauma and the clinical results of decompressive surgery in cervical spinal stenosis retrospectively.

Method: We treated 200 cases (98 cervical OPLLs and 102 CSMs) of cervical spinal stenosis for 8 years.

The effects of applying adhesion prevention gel on the range of motion and pain after TKA.

A mixed solution of sodium hyaluronate and sodium carboxymethylcellulose (HA/CMC) has been shown to be effective for decreasing postoperative adhesions in various kinds of surgeries. We evaluated the clinical efficacy and safety of HA/CMC gel on the early postoperative range of motion and pain relief after total knee arthroplasty (TKA). Thirty one patients who underwent bilateral TKA as a single-stage procedure for primary osteoarthritis were included in the study.

Surgical treatment of a giant lipoma in the parotid gland.

Recently, a case of deep-lobe lipoma with enucleation was reported, but frozen-section biopsy for the confirmation of the malignancy was not done. It has been suggested that lipoma in the deeper tissues should be regarded as a well-differentiated liposarcoma and be treated with wide excision. Our experience is that of a 75-year-old woman who had a mass with fat density in the deep lobe of the right parotid gland, which extended through the parapharyngeal and the buccal spaces.

Clinical application of accelerated osteogenic orthodontics and partially osseointegrated mini-implants for minor tooth movement.

Introduction: This article illustrates a new treatment system combining accelerated osteogenic orthodontics and osseointegrated mini-implants for minor tooth movement in severely compromised conditions. The procedures, advantages, efficacy, and indications of this method are discussed.

Methods: Three patients who needed minor tooth movement and orthodontic mini-implant treatment were recruited to use this combined technique; 1 required molar intrusion, and 2 required molar uprighting.

Overexpression of protein phosphatase non-receptor type 11 (PTPN11) in gastric carcinomas.

Background: Tyrosine phosphorylation and dephosphorylation by protein tyrosine kinases and phosphatases (PTPs), respectively, play crucial roles in cellular signal transduction. Protein phosphatase non-receptor type 11 (PTPN11) is a positive signaling PTP that activates RAS and ERK signaling. Also, the PTPN11 binds with CagA of Helicobacter pylori in gastric epithelial cells.

Analysis of temporary skeletal anchorage devices used for en-masse retraction: a preliminary study.

Introduction: The aim of this preliminary study was to analyze the results of en-masse incisor and canine retraction with temporary skeletal anchorage devices (TSADs) as the exclusive source of anchorage.

Methods: A retrospective clinical investigation supported by preliminary case reports was performed comparing pretreatment cephalometric radiographs with those taken after en-masse retraction of the 6 anterior teeth. The sample consisted of 17 nongrowing patients with an average age of 24.

Epidermoid cyst appearing as a malignancy-mimicking subcutaneous lesion on ultrasonography.

Purpose: It is challenging to diagnose epidermoid cysts on ultrasonography; except in typical, benign-appearing cases. The purpose of this study was to include epidermoid cysts in the differential diagnosis of diverse subcutaneous lesions, especially malignancy-mimicking lesions, as seen on ultrasonography.

Methods: We reviewed 19 cases of pathologically confirmed epidermoid cysts in 19 patients (male, 8; female, 11).

The combination effect of sodium butyrate and 5-Aza-2'-deoxycytidine on radiosensitivity in RKO colorectal cancer and MCF-7 breast cancer cell lines.

Background: The overall level of chromatin compaction is an important mechanism of radiosensitivity, and modification of DNA methylation and histone deacetylation may increase radiosensitivity by altering chromatin compaction. In this study, we investigated the effect of a demethylating agent, a histone deacetylase(HDAC) inhibitor, and the two agents combined on radiosensitivity in human colon and breast cancer cell lines.

Methods: In this study, we used RKO colorectal cancer cell line and MCF-7 breast cancer cell lines and normal colon cell lines.

Clinical application of a stereolithographic surgical guide for simple positioning of orthodontic mini-implants.

Aim: To describe a clinical application of a new surgical guide system that uses cone-beam computed tomography (CBCT) images, an implant-positioning program (SimPlant), and stereolithography to make a surgical guide for accurate placement of orthodontic mini-implants.

Methods: A patient who was planning to have orthodontic mini-implant treatment on the posterior maxilla was recruited to assess the feasibility of using CBCT images in an implant-positioning guide program (SimPlant 9.02, Materilise, Leuven, Belgium).

Two-component mini-implant as an efficient tool for orthognathic patients.

A new type of orthodontic mini-implant called the C-implant can be an effective alternative to conventional 1-component screws in orthognathic patients because of its particular design. Its small size and 2-component structure make it easily applicable for various types of difficult intermaxillary fixation cases such as 2-jaw orthognathic surgery, 1-jaw surgery with genioplasty, and orthognathic surgery without presurgical orthodontic treatment. The 2-part design highly resists fracture or deformation during placement and removal, and the long-span head allows the patient to easily attach intermaxillary elastics for traction.

Dental midline correction using two component C-orthodontic mini-implant.

Objectives: Correction of dental origin asymmetry with conventional orthodontic mechanics is at risk of developing side effects because of the inherent asymmetric nature of tooth-borne anchorage-based asymmetric mechanics. Recently, the concept of skeletal anchorage using mini-implants has been introduced in the field of orthodontics and have shown successful results. The aim of this study is to demonstrate the clinical application of osseointegration of surface treated two component mini-implants (C-implant) in managing dental midline correction.

TKA using the subvastus approach and lateral retinacular release in patients with permanent post-traumatic patellar dislocation: a report of two cases.

Permanent post-traumatic patellar dislocation is a rare condition, and total knee arthroplasty (TKA) can be performed for osteoarthritic knees with this condition. There have been only a few reports about using the standard medial parapatellar approach and extensive lateral release or extensor mechanism realignment for patients with permanent post-traumatic patellar dislocation. We performed two TKAs with using a subvastus approach and lateral release for osteoarthritic knees with permanent post-traumatic patellar dislocation.

Double-archwire mechanics using temporary anchorage devices to relocate ectopically impacted maxillary canines.

This case report introduces a novel double archwire mechanics concept using orthodontic mini-implants and a miniplate to relocate ectopically impacted maxillary canines in a 14-year-old female with a Class III subdivision left malocclusion. The objective of this orthodontic treatment was to salvage the maxillary lateral incisors so they could be used for conservative restorations upon completion of the orthodontic treatment and to guide the impacted maxillary canines to their correct anatomical positions. The authors report that an iatrogenic root resorption of the maxillary lateral incisors, which is caused by a direct root contact between teeth during the active relocating procedure, can be minimized by using double-archwire mechanics.

Chromomycosis presenting as soft-tissue mass: report of a case with MRI features.

Chromomycosis is primarily a skin disease that superficially presents as slowly growing, verrucous lesions, often warty or cauliflower-like in appearance. It may occasionally create a flat, plaque-like lesion in the skin but deep-seated tumorous presentation has not previously been reported. As the lesion is limited to the cutaneous and superficial subcutaneous tissues, hitherto reported cases have been described from the view point of dermatology and, so, without MRI study.

Reconstruction of scalp defect after Moyamoya disease surgery using an occipital pedicle V-Y advancement flap.

Scalp necrosis is an infrequent complication of Moyamoya disease surgery, which is more prevalent in the parietotemporal area. Because scalp vascularity is severely compromised after Moyamoya disease surgery, reconstruction of defects with local scalp tissue is challenging. To cover defects, a flap is needed that is highly vascularized and has great mobility and territory to avoid existing scars.

Clinical and radiographic results of unilateral transpedicular balloon kyphoplasty for the treatment of osteoporotic vertebral compression fractures.

Introduction: Most previous reports indicate that traditional bilateral kyphoplasty improves patient function and restores height of collapsed vertebral bodies, but limited data about the effects of unilateral kyphoplasty on clinical and radiological outcome are available.

Material And Methods: One hundred five patients were treated by unilateral kyphoplasty between January 2004 and December 2006. These patients underwent 105 operations to treat 132 vertebral compression fractures between T8 and L5.

Removal torque values of surface-treated mini-implants after loading.

Introduction: Although the sand-blasted, large-grit, and acid-etched surface-treated mini-implant (C-implant, CImplant Co, Seoul, South Korea) is designed to endure heavy and dynamic loads and offers high stability during orthodontic treatment, implications of its removal are still unknown. The purpose of this study was to evaluate the removal torque values (RTVs) of early-loaded mini-implants.

Methods: Sixty-four mini-implants (1.

Power Doppler needle-induced fremitus for breast localization.

Purpose: We attempted to identify the preoperative, sonography-guided breast localization technique which can be used in cases in which surgeons require the shortest incision route or exact localization of a lesion.

Materials And Methods: We performed a phantom study using a lesion-in-breast model, investigating the concept that the flash artifact is induced at the tip of the vibrating needle on power Doppler images, before attempting any clinical applications. In view of the results achieved in the phantom study, we applied this technique to patients referred to our department over a 2-year period.

Ruptured epidermal inclusion cysts in the subareolar area: sonographic findings in two cases.

Epidermal inclusion cyst of the breast is an uncommon benign lesion and it is usually located in the skin layer. We report here on two cases of ruptured epidermal inclusion cysts in the subareolar area, which is a very unusual location for these cysts and these lesions can be mistaken for breast malignancies.
