Objectives: Full thickness skin grafts (FTSG) offer several advantages; they are esthetically superb, have less postoperative shrinkage, and offer minimal postoperative pain and scar formation at the donor site. As a donor site of FTSG, the groin offers a relatively large area of skin with high elasticity. The aim of this study was to evaluate FTSG from the groin for reconstruction in oral and maxillofacial surgery. Materials and Methods: In a retrospective study, 50 patients (27 males, 23 females) who received FTSG from the groin were evaluated for their operation records, clinical photography, and medical records. Results: The width of skin from the groin was distributed from 2-8 cm (mean: 5.1 cm) at the donor site, while the long axis length was distributed from 3-13 cm (mean: 7.4 cm). A high number of patients, 47 patients (94%) out of 50, showed good healing at the donor site. Wound impairment was seen in 3 patients (6%), minor wound dehiscence in 2 patients, and severe wound dehiscence in 1 patient. In the recipient site, delayed healing was observed in 2 patients (4%). Conclusion: FTSG from the groin to repair soft tissue defects in reconstruction surgery is a good method due to the relatively big size of the graft, decreasing morbidity at the donor site, and higher graft survival rates.

The specialized structure of the upper eyelid ensures complete closure of the eye and eyeball sealing. An upper eyelid injury can cause various symptoms associated with eyeball trauma, not just scar formation or eyelid deformity. In this report, we describe a case of lagophthalmos observed after wound repair in a patient with a crushing injury caused by a grinder. Several surgical techniques are used to treat lagophthalmos or scar contracture. In most cases, a releasing procedure is performed after 6 months of initial repair. However, if the patient has severe symptoms that are not relieved by conservative care, early revision is inevitable. We describe a case of early lagophthalmos successfully resolved with pentagonal wedge resection, fat redistribution, and full-thickness skin grafting. After the revisional surgery, we observed that the patient regained the ability to completely close the injured eyelid, with restoration of function and favorable cosmetic outcomes. Pentagonal wedge resection to release a retracted structure, fat redistribution to prevent readhesion, and full-thickness skin grafting for enough amount of skin to regain upper eyelid function is useful for scar release and lagophthalmos following crushing injuries of the upper eyelid.

Background Full-thickness skin grafts (FTSGs) are generally considered unreliable for coverage of full-thickness finger defects with bone or tendon exposure, and there are few clinical reports of its use in this context. However, animal studies have shown that an FTSG can survive over an avascular area ranging up to 12 mm in diameter. In our experience, the width of the exposed bones or tendons in full-thickness finger defects is <7 mm. Therefore, we covered the bone- or tendon-exposed defects of 16 fingers of 10 patients with FTSGs. Methods The surgical objectives were healthy granulation tissue formation in the wound bed, marginal de-epithelization of the normal skin surrounding the defect, preservation of the subdermal plexus of the central graft, and partial excision of the dermis along the graft margin. The donor site was the mastoid for small defects and the groin for large defects. Results Most of the grafts (15 of 16 fingers) survived without significant surgical complications and achieved satisfactory functional and aesthetic results. Minor complications included partial graft loss in one patient, a minimal extension deformity in two patients, a depression deformity in one patient, and mild hyperpigmentation in four patients. Conclusions We observed excellent graft survival with this method with no additional surgical injury of the normal finger, satisfactory functional and aesthetic outcomes, and no need for secondary debulking procedures. Potential disadvantages include an insufficient volume of soft tissue and graft hyperpigmentation. Therefore, FTSGs may be an option for treatment of full-thickness finger defects with bone or tendon exposure.

Purpose: Skin grafting is used for the transfer of cutaneous tissue from one site of the body to another. To improve graft survival, close contact between the graft and the wound bed is essential for vessels to grow across the gap. Here, we introduce an easy and efficient dressing method to improve graft survival. Materials and Methods: A retrospective chart review was performed to identify patients who underwent split thickness skin graft and negative pressure wound therapy (NPWT) or conventional treatment between January 2007 and April 2015. Overall, 25 consecutive patients were included in the NPWT group and 49 were included in the conventional dressing group to compare the outcome of the procedure. The data were obtained from medical records, including age, sex, cause of the skin defect, size of graft, time for healing, wound preparation time, and complications. Results: Of the NPWT group, the average wound size was $147.04{\pm}146.74cm^2$ (range, $9{\sim}900cm^2$). With the exception of one patient, all wounds healed without the need for further procedure. The average duration of time required for the NPWT group, which was defined as removal of stitches (or staples) and no need for additional active dressing, was $6.4{\pm}1.97days$ (range, 5~15 days). The average time for the conventional dressing group was $10.78{\pm}2.38days$ (range, 5~15 days). Conclusion: NPWT can be used to cover regions in which wound healing does not occur fully or when neither tie-over nor compressive dressings are applicable. This treatment also reduced wound healing time and allowed earlier patient mobilization and hospital discharge.

Allogeneic hematopoietic stem cell transplantation (HSCT) is considered the optimal curative treatment for acute myeloid leukemia (AML), but some patients develop bone marrow relapse due to remnant leukemia, and few patients develop extramedullary relapse without bone marrow relapse. Isolated extramedullary relapse (IMER) is defined as extramedullary relapse without bone marrow relapse. IMER has been reported in various sites, including the skin, soft tissue, and central nervous system(CNS). Isolated CNS relapse is relatively rare and is associated with poor prognosis due to the absence of an optimal treatment for it. Reported herein is a case involving an adult AML woman who suffered from isolated extramedullary relapse in the CNS after allogeneic HSCT. She was treated with intrathecal chemotherapy and whole-brain and spine radiotherapy, followed by systemic chemotherapy. She is currently well, with no evidence of leukemia recurrence for over six years.

Volkmann's ischemic contracture is the end result of an untreated, delayed or Inadequately decompressed compartment syndrome in which muscle ischemia and necrosis have occurred. Once the muscle necrosis have happened, the involved muscle undergo permanent change into fibrous tissue. So secondary shortening and distal joint contracture will be a final outcome, which results in marked functional impairment of hand and forearm. Even though several procedures, such as muscle sliding operation has been attempted, overall results were far from satisfaction, compare to healthy opposite hand. The management of these unfavorable condition of the forearm and hand was regarded as one of challenging area in orthopedics. Recently new approach, using microsurgical technique which transfers functioning muscle unit, has been developed and its result was much better than any other methods in the aspect of an active motion. Among these musculocutaneous free flaps, gracilis has obtained special reputation due to its easiness to handle such as elevation of flap and reliable neurovascular pedicle. Other advantages are flexibility of flap size to adjust variable size of the defect in the forearm and minor morbidity of the donor site. Authors have performed 7 cases of functioning gracilis musulocutaneous free flap transplantation for the functional loss of forearm and hand due to Volkmann's ischemic contracture or muscle and skin defect due to severe trauma since November, 1981 till May, 1991. The results in most cases were satisfactory and acceptable.

Acute graft-versus-host-disease (GVHD) is characterized by selective damage to the liver, the skin, and the gastrointestinal tract. Following allogeneic hematopoietic stem cell transplantation, donor bone marrow (BM) cells repopulate the immune system of the recipient. We previously demonstrated that the acute intestinal GVHD (iGVHD) mortality rate was higher in MyD88-deficient BM recipients than that in the control BM recipients. In the present study, the role of MyD88 (expressed by donor BM) in the pathophysiology of hepatic GVHD (hGVHD) was examined. Unlike iGVHD, transplantation with MyD88-deficient T-cell depleted (TCD) BM attenuated hGVHD severity and was associated with low infiltration of T cells into the liver of the recipients. Moreover, GVHD hosts, transplanted with MyD88-deficient TCD BM, exhibited markedly reduced expansion of $CD11b^+Gr-1^+$ myeloidderived suppressor cells (MDSC) in the liver. Adoptive injection of the MDSC from wild type mice, but not MyD88-deficient mice, enhanced hepatic T cell infiltration in the MyD88-deficient TCD BM recipients. Pre-treatment of BM donors with LPS increased MDSC levels in the liver of allogeneic wild type BM recipients. In conclusion, hGVHD and iGVHD may occur through various mechanisms based on the presence of MyD88 in the non-T cell compartment of the allograft.

Pulmonary complications occur in 40~60% of patients who receive hematopoietic stem cell transplantation (HSCT) and are a source of substantial morbidity and mortality. Acute eosinophilic pneumonia (AEP) is an uncommon, non-infectious pulmonary complication occurring in HSCT recipients. We now report the case of a 52-year-old man with AEP who was treated with allogenic HSCT due to acute myeloid leukemia. He complained of fever, cough and dyspnea 390 days after allogenic HSCT. He also had skin and hepatic graft versus host disease (GVHD). Hypoxemia, diffuse pulmonary infiltrates on a chest x-ray and eosinophilia in bronchoalveolar lavage fluid were also noted in several tests. His symptoms, pulmonary infiltrates, hepatic dysfunction and skin lesions rapidly improved after treatment with corticosteroid therapy. Our case supports the idea that AEP is a late phase non-infectious pulmonary complication and one of the manifestations of chronic GVHD.

Background : Facial capillary malformations (CMs) rarely recede; they often become darker and raised in proportion to their growth. These malformations may hypertrophy in adulthood, resulting in increased disfigurement and dysfunction. Laser treatment is considered a first-line therapy for focal CMs, but thick wide lesions, which are accompanied by hypertrophy and have a well-circumscribed nodularity, may be treated with surgical excision and reconstruction. Methods : We retrospectively reviewed the records of 25 consecutive patients who had undergone complete or partial excisions of facial capillary malformations in our unit. After the excisions, the defects that encompassed their facial aesthetic units were subsequently covered by various methods, including primary closures, local flaps, expanded flaps, split-thickness skin grafts, and full thickness skin grafts. Results : The data demonstrated satisfactory results and reliability. Our patients were treated without significant complications, and all of the patients were moderately or fully satisfied with the outcome of their surgeries. Conclusions : Among the many reconstructive options for adult patients with facial capillary malformations, thick split-thickness skin grafts can be a good choice for the coverage of widely excised wounds.
