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 Ca²⁺ dynamics induced by cyclical stretching stimuli between the control group (normal dermal fibroblasts) and the keloid group (keloid‐derived fibroblasts). Each group was cyclically exposed to a two‐dimensional stretch (10% strain). A confocal laser microscope was used to examine intracellular Ca²⁺ for 30 min fluorescently. The fluorescence intensity ratio (Fluo‐8H/calcein red–orange) was used to evaluate intracellular Ca²⁺ concentration every 0.5 s. A calcium spike was a transient ratio increase of ≥ 20%. Receiver operating characteristic analysis was performed to determine the cutoff value of a normal calcium spike. Results No significant difference was observed between the keloid and control groups in the calcium signal response‐positive rates (26.9% vs. 25.0%; p = 0.9). However, the calcium spike amplitudes were significantly higher in the keloid group than in the control group (1.66 vs. 1.41; p = 0.02). The cutoff value was 2.12, and 9.6% of keloid‐derived fibroblasts exhibited multiple hypercalcium spikes. Discussion We are conducting further research based on the hypothesis that this keloid‐specific subpopulation triggers the pathogenesis of keloid formation, that is, collagen overproduction, accelerated angiogenesis, and chronic inflammation.

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. Therefore, the authors hypothesized that cyclical stretching also induces a specific Ca2+ spike in keloid-derived fibroblasts. METHODS: This in vitro study compared the intracellular calcium dynamics induced by cyclical stretching between control (human dermal fibroblasts) and keloid (human keloid-derived fibroblasts) groups. Each group was exposed to two-dimensional stretch using an originally developed stretch microdevice. Intracellular Ca2+ was observed for 5 minutes, including 30 seconds of baseline, under a fluorescent confocal laser microscope. The intracellular Ca2+ concentration was evaluated every 0.5 second using the fluorescence intensity ratio. A positive cellular response was defined as a rise of the ratio by greater than or equal to 20%. The normal response cutoff value was determined by receiver operating characteristic analysis. RESULTS: The keloid groups were significantly more responsive than the control groups (15.7% versus 8.2%; P = 0.029). In the cellular response-positive cells, the keloid groups reached significantly higher intracellular Ca2+ concentration peaks than the control groups (2.20 versus 1.26; P = 0.0022). The cutoff value was 1.77, and 10.4% of the keloid-derived fibroblasts exhibited a hyper-Ca2+ spike above the normal range. CONCLUSIONS: Keloid-derived fibroblasts with a hyper-Ca2+ spike might constitute a keloid-specific subpopulation. Hereafter, the authors will study whether the normalization of excessive intracellular Ca2+ concentration leads to keloid treatment in vivo. CLINICAL RELEVANCE STATEMENT: This study result provided a clue to the onset mechanism of keloids, which the authors hope will lead to the development of new therapy in the future.

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. METHODS: We conducted a retrospective study of 40 patients with pressure ulcers (69 sites). We calculated the significant difference in the incidence of wound dehiscence between the groups for the following 15 factors : age, obesity, emaciation, diabetes mellitus, smoking, ulcer site, musculocutaneous flap, methicillin-resistant Staphylococcus aureus, presence of two or more types of bacteria, albumin level, C-reactive protein level, white blood cell count, hemoglobin level, operative time, and ulcer size. RESULTS: Bacteria were detected in all wounds with early dehiscence, which was found in 28 (40.6%) of the 69 cases. C-reactive protein level, albumin level, musculocutaneous flap, and operative time were found to be risk factors for early wound dehiscence using the χ2-test and t-test. (P?=?0.011, 0.045, 0.018, and 0.003, respectively). CONCLUSION: The cause of dehiscence was considered to be surgical site infection. C-reactive protein level, albumin level, musculocutaneous flap, and operative time may be risk factors of the occurrence of early wound dehiscence. J. Med. Invest. 70 : 101-104, February, 2023.

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. METHODS: IRF vessels were examined in 200 bilateral computed tomography angiography scans performed in 100 patients. We examined branching patterns arising from the internal iliac artery and the origins of the skin perforators in the IRF. RESULTS: The branching patterns of the internal iliac artery were divided into three groups: perforators derived exclusively from the internal pudendal artery (78%), perforators derived from the internal pudendal artery and the inferior gluteal artery (18%), and perforators derived exclusively from the inferior gluteal artery (4%). The average number of perforators in the IRF was 1.5 ± 0.7. The number of perforators was significantly higher in women than in men. The perforator arteries were found exclusively around the medial and dorsal sides of the ischial tuberosity. CONCLUSIONS: We found that perforators in the IRF were stable. All cases had more than one skin perforator, which was mainly derived from the internal pudendal artery. Although perforators cannot be identified during flap elevation because the fatty tissue in the IRF is very thick, physicians must focus on preserving the perforator-containing fatty tissue around the ischial tuberosity.

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. This study aimed to quantify the aesthetic outcomes on using this flap and reveal the risk factors associated with nasal deformities. METHODS: Twenty patients underwent nasal reconstruction using the LNA flap with a cranial perforator adjacent to the nasal defect. Postoperative protuberant deformities were scored by 2 independent plastic surgeons using a 5-point Likert scale and classified as excellent, good, or poor. The risk factors of deformities were identified using univariate analyses. A nasal alar deviation index was developed to analyze correlations with flap harvesting. The sensory function was assessed by the Semmes-Weinstein test. RESULTS: Flaps survived in 19 patients (95%), and 1 flap showed distal necrosis. All arterial perforators used remained within 5 mm lateral to the boundary between the cheek and nasal ala. The flaps were most often used to cover 2 subunits, including the nasal sidewall defects. Protuberant deformities in 6 (30%), 8 (40%), and 6 (30%) patients were classified as excellent, good, and poor, respectively. Nasal defects involving more than 3 subunits caused severe protuberant deformity. Only 2 patients (5%) in the good and fair groups underwent additional debulking surgery. Nasal alar deviation was not significantly correlated with flap harvesting, when the nasal alar deviation index before and after surgery were compared. Sensory function was retained in all patients. CONCLUSIONS: Aesthetic outcomes and sensory function were good on using the LNA perforator flap as a propeller flap having a wide arc of rotation. This flap is suitable for nasal reconstruction involving less than 2 nasal subunits without any severe nasal alar deviation deformity. In addition, this flap allows for better outcomes because it requires less invasive 1-stage surgery.

Background : Patients with chronic limb-threatening ischemia are often on hemodialysis. It is unclear which skin perfusion pressure (SPP) values, i.e., those measured immediately after hemodialysis on a hemodialysis day or those measured on a non-hemodialysis day, reflect the actual wound healing course in chronic limb-threatening ischemia. Methods : Eighteen patients undergoing hemodialysis (49 measurements) who were treated for leg ulcers due to critical limb ischemia were included in the study. The SPP values were divided into two groups : those measured immediately after hemodialysis (HD day group) and those measured on non-hemodialysis days (non-HD day group). The wound healing outcomes were investigated. The cutoff SPP value for predicting wound healing was set to ≥ 35 mmHg. The sensitivity, specificity, positive predictive value, negative predictive value, and accuracy of SPP in each group were measured. The relationship between SPP and blood pressure was analyzed by regression analysis. Results : Significant differences were observed in the positive predictive value (HD day : 100%, non-HD day : 50% ; P = 0.002), The correlation coefficient was 0.698 in the HD day group and 0.292 in the non-HD day group. Diastolic blood pressure had a significant effect on SPP (P = 0.039). Conclusions : The measurements are best taken immediately after hemodialysis for more accuracy. J. Med.

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. METHODS: Our study group included 28 patients who underwent full-thickness lower eyelid reconstruction using a cheek rotation flap for anterior lamella reconstruction. We developed the drooping index to classify postreconstruction outcomes as good (index <1.2), fair (index between 1.2 and 1.5), and poor (index >1.5). We identified risk factors for a drooping deformity using univariate analyses (Mann-Whitney U or Spearman rank correlation, depending on data distribution). RESULTS: Overall, the drooping index ranged between 1.0 and 2.11, with an average value of 1.3. A good outcome was obtained in 11, a fair outcome in 12, and a poor outcome in 5 patients. Clinically severe ectropion was observed in five of the 17 patients in the fair and poor outcome groups, with four of these patients requiring revision surgery. Risk factors for postreconstruction drooping deformity included medial location of the tumor, resection involving more than 50% of the horizontal width of the lower eyelid, and dissection of subcutaneous tissue of the cheek extending below the zygomatic arch. CONCLUSIONS: A cheek rotation flap provides satisfactory outcomes for full-thickness reconstruction of the lower eyelid. Extension of dissection of subcutaneous tissue of the cheek below the zygomatic arch increases the risk of postsurgical drooping deformity. Our drooping index provides a quantitative measure of drooping deformity and is clinically useful to classify outcomes.

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. METHODS: This study included 52 patients who underwent reconstructive procedures using free ALT flaps. The delayed healing group included patients with wounds at the donor site that had not healed over 3 weeks after surgery, and the normal healing group included patients who showed wound healing within 3 weeks after surgery. Multivariate logistic regression models were created to identify the risk factors for delayed healing at the ALT flap donor site. RESULTS: Among the 52 patients, 24 (46.2%) showed delayed healing at the donor site, and 6 patients required additional operative treatment. A high preoperative body mass index (BMI), smoking, and skin grafting were found to be significantly associated with delayed healing at the ALT donor site. Of the 37 patients who underwent skin grafting, 23 (62%) experienced delayed healing at the donor site. CONCLUSIONS: A high preoperative BMI, smoking, and skin grafting were risk factors for delayed healing at the free ALT donor site. Skin grafting at the ALT donor site should be avoided in patients with a high BMI or a habit of smoking.

Flap transplantation has been an important procedure in plastic and reconstructive surgery to cover and fill various defects. Flap necrosis due to blood circulation failure leads to severe complications, especially in a patient undergoing reconstruction concerning the body cavity after tumor ablation. Surgical procedures for flap transplantation have been further improved and developed. We have reviewed from the random pattern flap to the newest procedure, the perforator flap. Perforator vessels were investigated in the process of development of the fasciocutaneous flap and have become important for blood supply of the skin flap. Blood circulation of the flap has become more stable and reliable than ever with the development and findings of the perforator vessels. Further development of a skin flap will be based on the perforasome concept, which involves the study of the territory and linking of perforator vessels. J. Med. Invest. 63: 159-162, August, 2016.

Pilonidal sinus is a cystic disease that occurs most often in the sacrococcygeal region. Surgical excision and coverage with a skin flap require postoperative bed rest. Most affected patients are young adults who find it difficult to obtain adequate postoperative bed rest owing to their work. The purpose of this study is to review the effectiveness of our ambulatory surgery procedure for pilonidal sinus, which involves tract excision and open treatment followed by at-home irrigation. We reviewed the 9 cases of chronic pilonidal sinus treated at our out-patient clinic by ambulatory surgery consisting of open excision without skin closure. Patients were sent home after careful observation for hemostasis at the surgical site. Postoperative wound treatment and irrigation were performed at home by the patients themselves. The mean immediate postoperative follow-up period was 22.3 days (13 to 31 days), and the mean number of follow-up visits was 3.3. No serious complication and recurrence was noted during the long-term follow-up period of 26.3 months (1 to 60 months). Although the healing time following our ambulatory procedure was not short, no postoperative rest was required, and the recurrence rate was zero. We believe this procedure is useful for selected patients with pilonidal sinus. J. Med. Invest. 63: 216-218, August, 2016.

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. We conducted a retrospective study to assess the effectiveness and reliability of this technique for digital mucous cyst excision. The study group comprised 26 patients treated for 28 digital mucous cysts. The flap was elevated on the nail matrix to expose the distal interphalangeal joint capsule. To preserve the skin in cases in which the skin covering the cyst was exceptionally thin, we did not excise the upper part of the cyst wall. Excision of the cyst and stalk was successful in all cases. Additional excision of the joint capsule or osteophyte(s) was achieved in 20 cases and 5 cases, respectively. No flap necrosis, skin defect or nail deformity resulted. Three of the cysts recurred and were treated successfully by reoperation involving the same flap elevation technique. We conclude that the proximal nail fold flap is useful for excision and reliable for wound coverage after digital mucous cyst excision. J. Med. Invest. 63: 278-280, August, 2016.

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. We evaluated the efficacy of touch-up surgery, either reduction mammaplasty or mastopexy, performed on the contralateral breast for symmetrization. METHODS: Reduction mammaplasty was performed on the contralateral breast in 2 patients and mastopexy was performed on the contralateral breast in 1 patient after reconstruction surgery following cancer resection, between 2008 and 2014. We reviewed each patient's medical record for general clinical information and for the methods of breast cancer resection and breast reconstruction used, wait time between breast cancer resection and touch-up surgery, preservation of the sensitivity of the nipple-areola complex after the touch-up surgery, and aesthetic outcome (based on visual analog scale score). RESULTS: Wait times in the 3 cases were 4, 9, and 18 months. Nipple-areolar sensitivity was well preserved in all 3 cases. Aesthetic outcomes were judged "excellent" or "very good." CONCLUSION: Revision surgery on the contralateral breast 4 to 18 months after breast reconstruction substantially improves the aesthetic outcome. J. Med. Invest. 63: 281-285, August, 2016.

BACKGROUND: Cutaneous malignant melanoma has a poor prognosis. The detrimental effect of incisional biopsies on the outcome of malignant melanoma has been debated. The aim of this study was to determine the effect of the presence and type of biopsy on the prognosis of malignant melanoma. METHODS: The medical records of 109 malignant melanoma patients treated at Tokushima University Hospital from 1983 to 2007 were reviewed. After excluding 28 cases with stage 0 disease or incomplete data, 81 cases were analyzed in detail with respect to patient sex, age, tumor site, clinical stage at diagnosis, presence of ulceration or lymph node metastasis, and prognosis. The five-year survival and five-year disease-free survival rates of patients who underwent incisional or excisional biopsies were compared with those who did not undergo a biopsy. RESULTS: The male-to-female ratio was 1:1.19. The mean age was 61.3 years (range, 19-93 years). The most common site was a lower extremity, and the most common clinical stage was stage II. No significant differences in clinicopathological features, five-year survival rates, and five-year disease-free survival rates were observed among the three groups. CONCLUSIONS: The presence and type of biopsy neither affected the metastatic rate nor the prognosis of malignant melanoma. The use of incisional biopsies is not encouraged because tumor thickness cannot be measured accurately. However, they may be helpful for confirming the diagnosis if an excisional biopsy cannot be performed.

BACKGROUND: Hidradenitis suppurativa is a chronic and often refractory skin disease that can require radical excision of the full layer of fatty tissue under the lesion. Closure using a split-thickness skin graft often results in depression deformity and lack of tissue flexibility. We have developed a two-stage procedure to preserve fatty tissue during radical excision and apply an artificial dermis graft, and we have performed this procedure in 18 patients (33 lesions). OBJECTIVE: To describe our two-stage procedure and report results of the procedure in our patient series. METHODS: In the first step, all diseased skin including the superficial subcutaneous fatty tissue is excised; normal deep subcutaneous fatty tissue is preserved. Artificial dermis is then grafted to the preserved fatty tissue. Two weeks later, split-thickness skin grafts are applied to the skin defects. We evaluated graft success, any recurrence, and postoperative appearance in our patients, who were followed up for 8 to 36 months. RESULTS: All 32 skin grafts were successful. There was only one recurrence, which was treated using reoperation, and postoperative appearances were good. CONCLUSIONS: Our new procedure incorporating artificial dermis appears to be a good treatment option for advanced hidradenitis suppurativa.

Severe traumatic bone and soft-tissue defects are often treated by lower leg amputation. The amputation level becomes a very important factor with respect to the patient's basic daily activities. We report the case of a 51-year-old man who was referred to us with severe traumatic metatarsal bone and dorsum pedis skin and soft-tissue defects. To avoid amputation, a free fibular osteomyocutaneous flap incorporating the soleus muscle was used to reconstruct the second and third metatarsal bones and the soft-tissue defect, respectively. Now, 2 years after the procedure, the patient is able to walk independently. To the best of our knowledge, this is the first report of use of such a composite transfer for a complex midfoot defect.
