Two-stage cranial reconstruction with a custom-made titanium plate using a preliminary bipedicled scalp flap : A case report.

A 75-year-old woman presented with scalp and cranial defects caused by implant exposure, infection,and cranial necrosis following multiple craniotomies. To reduce the risk of complications after cranioplasty, weplanned a two-stage cranial reconstruction. A wide bipedicled scalp flap with a long longitudinal axis above the cranium covered the scalp defect after debridement, and skin grafting was performed on the periosteum after flap harvesting during the first surgery.

Plantar pressure and shear stress during gait in people with diabetic neuropathy.

Aims: Diabetic foot ulcers are a leading cause of lower extremity amputations, significantly affecting the quality of life. Excessive plantar surface pressure and shear stress are key factors in ulcer development and aggravation. This study aimed to determine the association of these forces with the progression of diabetic peripheral neuropathy to help in foot-ulcer treatment and prevention.

Total Contact Cast after Sole Free Flap Reconstruction for Early Ambulation.

 Free flap reconstruction can be performed in patients with chronic limb-threatening ischemia (CLTI). However, early walking training may increase the risk of wound dehiscence and prolong hospitalization. Total contact cast (TCC) treatment effectively addresses diabetic plantar ulcers by immobilizing the foot and distributing weight away from the ulcer area.

Specific Calcium Signal Responses in Human Keloid-Derived Fibroblasts During Cyclical Stretching: Basic Research.

Background: Keloids most commonly develop in the regions where the skin is constantly stretched. Although some keloid-derived fibroblasts exhibit higher single calcium spikes than normal dermal fibroblasts during short-time cyclical stretching, the calcium signal responses to long-time stretching remain unclear.

Methods: This study compared the intracellular Ca dynamics induced by cyclical stretching stimuli between the control group (normal dermal fibroblasts) and the keloid group (keloid-derived fibroblasts).

Functional outcomes of reconstructive flap surgery for soft tissue sarcoma: Long-term outcomes of functional restoration using innervated muscle transplantation.

Functional outcomes associated with prognostic factors and innervated muscle transplantation after wide soft tissue sarcoma resection remain unclear. We retrospectively examined the functional outcomes of reconstructive flap surgery for soft tissue sarcoma. Twenty patients underwent innervated muscle transplantation with pedicled or free flaps for functional reconstruction of resected muscles.

Reconstruction methods for and cosmetic evaluation of external nasal tumour resections: flap versus graft.

Nose reconstruction is challenging given the three-dimensional structure and free edge, and various methods have been reported. In general, local flaps provide cosmetic outcomes that are better than those following skin grafts, but there are no published comparative studies on Asians. To determine whether local flaps or skin grafts may optimally be used to reconstruct external nasal defects among Asians.

Effect of joint limitation and balance control on gait changes in diabetic peripheral neuropathy.

Aims: This study analyzed the gait patterns of diabetic peripheral neuropathy (DPN) patients and changes in the center of mass sway to prevent the formation and recurrence of foot ulcers.

Methods: Forty-two subjects were divided into the diabetes mellitus (DM), DPN, and diabetic foot ulcer (DFU) groups. We measured the range of motion (ROM) of the lower limb joints in the resting position and the center of mass sway in the standing position.

Risk factors for early wound dehiscence by surgical site infection after pressure ulcer surgery.

Aims: The most common postoperative complication when treating a pressure ulcer with a flap or primary closure is early wound dehiscence. In this study, we aimed to investigate the cause of early wound dehiscence and its associated risk factors. Early wound dehiscence was defined as the wound dehiscence within the post operation period where no weight or tension is applied to the wound.

Cyclical Stretching Induces Excess Intracellular Ca2+ Influx in Human Keloid-Derived Fibroblasts In Vitro.

Background: The incidence of keloids is higher in the case of darker skin. It is more common in the parts exposed to stretching (thorax, abdomen, and joints). Cyclical stretching reportedly induced each Ca2+ spike through differential mechanosensitive channels in human synovial and dermal fibroblasts.

Nationwide time-series surveys of pressure ulcer prevalence in Japan.

Objective: The Japanese Society of Pressure Ulcers (JSPU) has two purposes: first, to improve knowledge and skills among health professionals related to preventing and managing pressure ulcers (PUs); and second, to represent those in the field managing PUs, including with government and health authorities. Since 2006, JSPU has conducted fact-finding surveys about every four years to identify PU prevalence in Japan (2006, 2010, 2013 and 2016). Based on the prevalence identified by these surveys, an attempt was made to validate the achievements of JSPU's activities.

Radiographic Study Evaluating Perforator Vessels in the Ischiorectal Fossa for Safe Elevation of Island Flaps.

Unlabelled: Perforator flaps based on the ischiorectal fossa (IRF) (ie, internal pudendal artery perforator flaps) are useful for perineal reconstruction. The three-dimensional characterization of perforator arteries in the IRF remains unclear, as the IRF contains thick adipose tissue as well as organs, such as the rectum, vagina, and urethra. This study aimed to evaluate perforators in the IRF to guide the safe elevation of skin flaps designed based on the IRF.

Relationship between fluctuations in skin perfusion pressure values and wound healing in patients with chronic limb-threatening ischemia undergoing hemodialysis.

Background : Patients with chronic limb-threatening ischemia are often on hemodialysis. It is unclear which skin perfusion pressure (SPP) values, i.e.

Suitability of the Microvascular Anastomotic Coupler System for Small Spliced Vein Grafts.

Microvascular anastomotic coupler system is used in vascular surgical procedures. By using this device, vascular anastomosis can be performed faster and more easily. It is often used for venous anastomosis during microsurgical reconstruction.

A Case of Macrodystrophia Lipomatosa of the Lower Extremity: An Effective Measuring of the Dynamic Plantar Pressure for Severe Congenital Deformity.

Macrodystrophia lipomatosa is a rare, congenital, non-hereditary form of localized gigantism characterized by abnormal fibroadipose tissue proliferation. Here, we report a case of a 39-year-old male with macrodystrophia lipomatosa of the whole left extremity with refractory foot ulcer. Imaging showed fibroadipose tissue proliferation and severe giant deformities of the second and third toes.

Lateral Nasal Artery Perforator Flap for Nasal Reconstruction: Clinical Applications and Risk Factors Associated With Nasal Deformities.

Background: Nasal reconstruction is challenging because of the difficulty in balancing superior aesthetic outcomes and less invasive surgery. The use of the lateral nasal artery (LNA) perforator flap has been reported for nasal reconstruction. However, few reports have described appropriate applications of nasal reconstruction and assessments of nasal deformity.

Analysis of Risk Factors Associated With Drooping Deformity After Lower Eyelid Reconstruction: A Newly Developed Drooping Index.

Background: Lower eyelid reconstruction is challenging because of the risk of severe postreconstruction deformities of the lower eyelid, such as drooping, entropion, and ectropion. However, the risk factors for these postreconstruction deformities are unclear. The present study aimed to quantify the drooping deformity of the lower eyelid after reconstruction using a cheek rotation flap and to identify risk factors associated with postreconstruction deformities.

Interpretation of bulk nitrogen and carbon isotopes in archaeological foodcrusts on potsherds.

Rationale: Foodcrust, the charred deposit adhering to the surface of containers, is a possible source of information on the function of ancient vessels and the subsistence of prehistoric humans. While the carbon isotope ratios in those materials are useful in detecting the usage of C plants, the reliability of nitrogen isotopic signatures has not been fully investigated.

Methods: The validity of bulk nitrogen isotope ratios has previously been investigated in coastal or riverine environments, where multiple resources from terrestrial and aquatic ecosystems were available, but not in terrestrial settings which provide a simpler mixing of terrestrial animals and plants.

The perifascial areolar tissue and negative pressure wound therapy for one-stage skin grafting on exposed bone and tendon.

Background: Factors such as exposed bones or tendons can inhibit wound healing and make it a lengthy process unless aggressive debridement or vascularized flap surgery are performed. We have developed a new procedure involving simultaneous application of a skin graft and perifascial areolar tissue (PAT) and negative pressure wound therapy.

Methods: Of 8 patients with wounds, bones, tendons, and thick fascia were exposed in 4, 2, and 2 cases, respectively.

Risk factors for delayed healing at the free anterolateral thigh flap donor site.

Background: The free anterolateral thigh (ALT) flap has been widely used for various kinds of reconstructions. However, delayed healing at the donor site occasionally occurs due to wound dehiscence or the partial loss of grafted skin at the donor site. The aim of the present study was to identify reliable predictive factors for delayed healing at the donor site after the harvest of a free ALT flap.

Topical application of nitrosonifedipine, a novel radical scavenger, ameliorates ischemic skin flap necrosis in a mouse model.

Ischemic skin flap necrosis can occur in random pattern flaps. An excess amount of reactive oxygen species is generated and causes necrosis in the ischemic tissue. Nitrosonifedipine (NO-NIF) has been demonstrated to possess potent radical scavenging ability.

Reduction mammaplasty and mastopexy for the contralateral breast after reconstruction surgery following cancer resection: A report of 3 cases.

Background: Breast reconstruction generally involves autologous tissue transplantation and placement of a mammary prosthesis. When the patient's breasts are extremely large and ptotic, breast reconstruction often results in significantly asymmetrical appearance. However, a good aesthetic outcome after reconstruction surgery following cancer resection is an important quality-of-life factor.

Proximal nail fold flap for digital mucous cyst excision.

The skin covering a digital mucous cyst is often very thin and is often excised with the cyst. Thus, transfer of a skin flap is needed for the defect. We have developed a proximal nail fold flap technique by which the thin skin covering the cyst can be preserved.
