Three-dimensional anatomical structure formed by granule cell layer and pyramidal cell layer in human hippocampus.

In the human hippocampus, the pyramidal layer consists of the inferior aspect of the hippocampus which is organized segmentally. Each segment, together with granule layer of the dentate gyrus, exhibits structural unity. In humans, ellipsoidal protrusions called pyramidal hillocks (PHs), which consist of a thick pyramidal cell layer (PL), are present in the inferior aspect of the hippocampus, and are segmentally organized along a longitudinal axis.

Minced Skin Grafting for Promoting Wound Healing and Improving Donor-Site Appearance after Split-Thickness Skin Grafting: A Prospective Half-Side Comparative Trial.

Background: Minced skin grafting is a procedure that involves mincing of the harvested skin and grafting it back onto the wounds. The authors aimed to investigate whether minced skin grafting reduces the healing time and improves the sequential postoperative appearance of donor sites.

Methods: A single-center, two-treatment, half-side comparative study was performed.

A Perifascial Areolar Tissue Graft With Topical Administration of Basic Fibroblast Growth Factor for Treatment of Complex Wounds With Exposed Tendons and/or Bones.

The management of wounds with tendon and/or bone exposure is challenging because of the insufficient blood supply to the wound bed. We describe our experience with 19 patients using a perifascial areolar tissue (PAT) graft with topical administration of basic fibroblast growth factor (bFGF) in the treatment of complex wounds with exposed tendons and/or bones in the extremities. Using a PAT graft is minimally invasive and technically easy, and the donor site is relatively preserved.

The Double Volar Flap Technique for Aesthetic Repair of Syndactyly and Polysyndactyly of Toe without Skin Grafting.

Background: Aesthetic repair of syndactyly of the toes is desirable because patients may have psychological concerns about its appearance. There are 2 important factors for the aesthetic repair of syndactyly of the toe. One is to hide the operative scar from the visual site (dorsal site), whereas the other is to create an interdigital space close to the normal anatomical skin characteristics (2 general types of skin: glabrous and hairy).

Perifascial areolar tissue grafting for treating syndactyly with bone fusion in patients with Apert syndrome.

Complete syndactyly with bone fusion in patients with Apert syndrome was treated using perifascial areolar tissue (PAT) grafts via a two-stage surgery (i.e. bone separation using inter-bone PAT graft insertion followed by web separation and reconstruction with full-thickness skin grafts).

Correction of Late Posttraumatic Enophthalmos Using an Antral Balloon.

Enophthalmos is the posterior displacement of the ocular globe within the bony orbit. Correction of late posttraumatic enophthalmos is one of the most challenging surgical procedures. We have performed a corrective procedure for late enophthalmos using an antral balloon, with or without minimal bone grafting.

One-piece bone flap osteotomy using thread wire saw for fronto-orbital advancement with distraction osteogenesis in craniosynostosis.

Purpose: The objectives of this study are to describe our new technique of one-piece bone flap osteotomy for fronto-orbital advancement with distraction osteogenesis in craniosynostosis using a thin, flexible, and safe thread wire saw (the T-saw) and to compare the results with those of classic osteotomy using an osteotome.

Methods: Initial osteotomy is performed between two pterion burr holes using a craniotome with a guarded footplate. The outer sphenoid wing and lateral orbital rim are separated using a reciprocating saw.

Incidence of lower eyelid complications after a transconjunctival approach: influence of repeated incisions.

Although many authors have described advantages of the transconjunctival approach, few reports describe risks of postoperative lower eyelid complications with repeated incisions. The objective of this study was to investigate whether the incidence of postoperative lower eyelid complication using the transconjunctival approach was different, depending on the time of incision. Patients who underwent orbital bony surgery at the Kanazawa Medical University Hospital between 1996 and 2012 were reviewed.

Repair of orbital fracture: the antral balloon with implantable reservoir technique.

The antral balloon technique is a useful procedure for the treatment of orbital fracture. Its advantages include being able to apply it without any donor-site morbidity. However, the saline injection catheter, which is inserted nasally from the natural ostium, sometimes causes discomfort.

Intraoperative acquired pressure ulcer on lower lip: a complication of rhinoplasty.

Device-related pressure ulcers are not rare. However, few studies have reported pressure ulcers of the lower lip. We encountered 2 patients with an intraoperative pressure ulcer on the lower lip caused by an endotracheal tube during rhinoplasty.

The human hippocampus observed by scanning electron microscopy (SEM): the dentate gyrus is made of an array of the neuronal lamellae.

Scanning electron microscopy (SEM) was employed to clarify the three dimensional structure of the human hippocampus.The polymorphic layer was L-shaped in coronal histological sections. The superior limb and lateral two thirds of the inferior limb formed a continuous plate.

Aggressive remodelling with pedicled skin flaps of the volar surface for the release of contractures of the fingers.

We treated contractures of fingers with one or several pedicled skin flaps on one or both sides of the scar, depending on the site and spread of the scar. The length of the flap was equivalent to half the circumference of the unaffected finger, or the distance between bilateral midlateral lines. The width of the flap was the same as the distance between the scar and the midlateral line.

Recurrent meningioma with metastasis to the skin incision--case report.

A 70-year-old woman presented with meningioma with metastasis to the skin incision. Neuroimaging demonstrated a tumor of the falx extending to the frontal bone. The tumor was grossly totally resected through a coronal skin incision.

A case of Beare-Stevenson cutis gyrata syndrome confirmed by mutation analysis of the fibroblast growth factor receptor 2 gene.

This paper reports a case of Beare-Stevenson cutis gyrata syndrome confirmed by DNA analysis of the patient's fibroblast growth factor receptor (FGFR) genes. At birth, the patient had ocular proptosis, a red nevus with skin tags on her forehead and an umbilical stump. She developed craniosynostosis, craniofacial dysmorphism and hydrocephalus.
