    ABSTRACT: This case report reviews features of negative pressure wound therapy, particularly for the exposed Achilles tendon, and describes an additional effective procedure. An 87-year-old man presented with a soft-tissue defect measuring 3×5 cm with the exposed Achilles tendon as a sequela of deep burn. The condition of his affected leg was ischemic because of arteriosclerosis. We used negative pressure wound therapy and made 2 longitudinal slits penetrating the tendon to induce blood flow from the ventral side to the dorsal surface. By this combination therapy, the surface of the exposed Achilles tendon was completely epithelialized and the tendon was spared without disuse syndrome. The authors conclude that this combination therapy is useful for covering the widely exposed tendon in aged patients.

    ABSTRACT: Objective: Anthropological studies divided the Japanese into the Yayoi migrants, who had narrow eye, no visible superior palpebral crease, and high-positioned round supraorbital margins for cold tolerance, and the Jomon natives, who had wide eye, visible superior palpebral crease, and low-positioned straight supraorbital margins, thus suggesting an anatomical discrepancy between the vertical palpebral fissure and the height of the supraorbital margin. Because Japanese subjects without visible superior palpebral crease open their eyelids by lifting the eyebrows with the anterior lamella owing to increased tonic contraction of the frontalis muscle, we hypothesized that persistently lifting the eyebrows in primary gaze mechanically remodels the supraorbital margin to be high positioned and round. Method: We evaluated whether subjects without visible superior palpebral crease persistently lifted their eyelids more than subjects with visible superior palpebral crease, whether the presence of persistently lifted eyebrow in primary gaze affected the relative height of the supraorbital margin in coronal view 3-dimensional computed tomography imaging, and whether the shape of the supraorbital margin in the coronal view affected that in the sagittal view 3-dimensional computed tomography imaging. Results: Eyebrow height in subjects without visible superior palpebral crease was significantly larger than that in subjects with visible superior palpebral crease. The supraorbital margin of subjects without visible superior palpebral crease who persistently lifted the eyebrows in primary gaze was higher (rounder) and more obtuse than that of Japanese subjects with visible superior palpebral crease who did not. Conclusions: The mechanical pressure applied to the supraorbital margin by persistently lifting the eyebrows appears to functionally, rather than genetically, create the high (round) and obtuse supraorbital margin.

    ABSTRACT: We report a patient with primary systemic AL amyloidosis who suffered from remarkable bilateral cervical lymphadenopathy. Intensive chemotherapies, including two cycles of high-dose melphalan with autologous peripheral blood stem cell transplantation, were insufficiently effective for both the lymphadenopathy and amyloidogenic IgGλ-type M-protein in serum, but the patient showed complete haematological remission after extensive surgical removal of enlarged lymph nodes that had massive depositions of λ-type immunoglobulin light chain-derived amyloid. Lymphadenectomy may be a possible therapeutic approach with regard to both cosmetic and haematological aspects in primary systemic AL amyloidosis patients with focal lymphadenopathy.

    ABSTRACT: The tumescent technique, which involves injection of large volumes of dilute epinephrine solution into subcutaneous fat, has been shown to markedly increase the safety of liposuction surgery, which is associated with risks of blood loss. The authors use this technique during burn surgery and developed a practical method of determining the amount of solution injected. The authors have applied the tumescent technique consisting of subeschar infiltration of dilute epinephrine (1 mg/L) in thermoneutral (37 degrees C) saline. Preoperatively, a 5 x 5 cm square grid pattern is drawn on the burn wound, which facilitates estimation of the amount of infiltrated solution. The authors injected 20 ml of solution per square in the grid. Ten consecutive patients underwent 15 surgical procedures for tangential excision and split-thickness skin grafting. There were no complications during the intraoperative or postoperative period. Their method using a grid pattern drawn on the tissue being treated by the tumescent technique in burn surgery facilitates the excision of burn eschar.

    ABSTRACT: We report the long-term results of nail fusion plasty in eight duplicated thumbs. These eight cases were hypoplastic, with nails less than 80% the size of that on the normal side. We operated on these duplicated thumbs using a technique that we developed. We evaluated postoperative nail shape in our series using both our and Tada's scoring systems. The average follow-up period was 12 years. Excellent results were obtained in six cases, with natural-looking nails and even curvature. One case showed acceptable results. Only one case had uneven curvature and a gap in the nail. To reconstruct a natural-looking nail, it is important to correctly design and suture together two nails under no tension. To obtain one nail with even curvature, bones are left floating so that the nail can grow with a natural transverse curve without interference. This technique yielded promising results on long-term follow-up.
