    UNLABELLED: No standards for the assessment of axillary odor intensity and the effects of therapy for osmidrosis have been established. This study presents an objective method for assessing odor severity in patients with osmidrosis and investigates the volatile odorants and skin flora. METHODS: The odor intensity was measured pre- and postoperatively using an industrial odor sensor in 79 patients with osmidrosis. Cultures of the axillary skin were obtained during skin flap surgery. Volatile odorants of the patients were assessed using an odor-sensor gas chromatograph mass spectrometer, and samples collected from clothing worn by the patients before and after surgery. The skin pH of the axilla was measured before and after surgery. The locations of odorants and bacteria in the skin were observed using electron microscopy. RESULTS: The mean patient age was 28.8 years, and the male-to-female ratio was 4:3. The odor significantly decreased from 52.6 preoperatively to 20.5 postoperatively (P < 0.001). The bacterial flora on the skin included mostly Staphylococcus. Multiple causative substances (volatile proteins) were identified on gas chromatography. The mean preoperative axillary skin pH was 6.21, which was significantly different than that of patients without osmidrosis (5.92; P < 0.01). CONCLUSIONS: An odor sensor accurately assesses odor intensity in patients with osmidrosis. The neutralization of axillary pH may promote the production of odorants by creating the optimal pH for bacterial growth. Odor sensor and pH values can be used pre- and postoperatively as objective assessment measurements for patients with osmidrosis.

    Objective: The choice between local flap designs for burn reconstruction is largely shaped by aesthetic, vascularity, procedural complexity, and wound-closure considerations. However, another key consideration is how well specific local flap designs release post-burn scar contractures. This is because constant tension on wound edges can generate pathological scarring. However, the ability of specific local flap to release post-burn scar contractures is poorly understood. This question was addressed by this study of patients who underwent local flap surgery to release post-burn scar contractures.Methods: The flap type, its original size, and the degree to which the flap extended 6 months after surgery were recorded.Results: Of the 40 patients enrolled, 20 received an island flap and 20 received a skin-pedicled flap. The scars were most commonly located on the anterior chest, axilla, and cubital fossa, followed by the lateral chest, abdomen, thigh, and popliteal fossa. Six months after surgery, the skin-pedicled and island flaps had extended on average by 1.53-and 1.28-fold, respectively.Conclusions: While it was technically easier to transfer island flaps to the recipient site, they released contractures less effectively than skin-pedicled flaps. The postoperative extensibility of flaps should be considered when determining which flap design is optimal for the individual patient. (C) 2017 Elsevier Ltd and ISBI. All rights reserved.

  • Periauricular Keloids on Face-Lift Scars in a Patient with Facial Nerve Paralysis. Reviewed International journal

    Keloids are caused by excessive scar formation that leads to scar growth beyond the initial scar boundaries. Keloid formation and progression is promoted by mechanical stress such as skin stretch force. Consequently, keloids rarely occur in paralyzed areas and areas with little skin tension, such as the periauricular region. Therefore, periauricular incision is commonly performed for face lifts. We report a rare case of keloids that arose from face-lift scars in a patient with bilateral facial nerve paralysis. A 51-year-old Japanese man presented with abnormal proliferative skin masses in bilateral periauricular scars. Seventeen years before, he had a cerebral infarction that resulted in permanent bilateral facial nerve paralysis. Three years before presentation, the patient underwent face-lift surgery with periauricular incisions. We diagnosed multiple keloids. We removed the masses surgically, closed the wounds with sutures in the superficial musculoaponeurotic system layer to reduce tension on the wound edges, reconstructed the earlobes with local skin flaps, and provided 2 consecutive days of radiotherapy. The wounds/scars were managed with steroid plasters and injections. Histology confirmed that the lesions were keloids. Ten months after surgery, the lesions did not exhibit marked regrowth. The keloids appeared to be caused by the patient's helmet, worn during his 3-hour daily motorcycle rides, which placed repeated tension on the periauricular area. This rare case illustrates how physical force contributes to auricular and periauricular keloid development and progression. It also shows that when performing surgery with periauricular incisions, care should be taken to eliminate wound/scar stretching.

    This study aimed to establish objective diagnostic criteria and optimize treatment selection for axillary osmidrosis by analyzing the ABCC11 gene single nucleotide polymorphism (SNP), axillary skin pH, and resident microbiota in 216 individuals. The findings demonstrated clear correlations between odor intensity and changes in the axillary environment before and after surgery. These factors proved useful as objective indicators for diagnosis and treatment planning. In particular, the significance of combining genetic and environmental assessments for distinguishing axillary osmidrosis from olfactory reference syndrome was highlighted. The results are expected to contribute to a more scientific understanding and the development of non-invasive management approaches for axillary osmidrosis.
