Two-stage surgical treatment for medially angulated great toes in Apert feet by wedged corrective osteotomy with distraction of the inter-metatarsal space: A case report.

BACKGROUND: One of most severe clinical problems related to Apert foot anomalies is medial angulation deformities of the great toe as the foot grows. CASE PRESENTATION: The patient was a 22-month-old Japanese child with Apert syndrome, who had broad bilateral great toe showing medially angulated deformity. We performed two-stage surgical treatment including distraction of the remarkable narrowing the first inter-metatarsal space using an external distractor device, and the corrective wedge-osteotomy of the first metatarsal with a graft of wedged bone in the reverse direction and inter-positioning of the resected local bone between the first and second metatarsal to preserve the space. At 3 years after surgery, the patient did not have any disturbance of gait and could wear normal shoes without weight-bearing pain, and was satisfied with the appearance of the great toes. CONCLUSION: The two-stage surgical method could be an option for surgical treatment of Apert feet.

Correction of Cryptotia With Double Z-plasty:Modified Large Z-plasty Technique.

Some cases of moderate or severe cryptotia are accompanied by a shortage of the helix. Although various operative techniques for correcting cryptotia have been reported, elongation of the helix is not considered in most of those techniques. In cases of a shortage of the helix, a drooped wide helix like a constricted ear or a cranially and posteriorly hypoplastic ear, which is characteristic of cryptotia, can appear after surgery if the helix has not been elongated. We previously reported a large Z-plasty technique that has become one of the popular techniques for correcting cryptotia. However, satisfactory results are not always achieved by using this technique in cases with a shortage of the helix. We developed a new technique (double Z-plasty) in which a small Z-plasty in the helical rim is added to the usual large Z-plasty technique. An improved helical shape and enlargement of the ear can be achieved by using this technique. Almost all types of cryptotia can be treated by appropriately using the large Z-plasty and double Z-plasty techniques.

New Concept for Severely Burned Ear Reconstruction: Grafting of the Frame Using Banked Ear Cartilage Combined with Costal Cartilage.

Damage and loss of ear cartilage can easily occur in a burned ear accompanied by severe extensive burns due to exposure of the cartilage or chondritis. Deformity can also occur due to later development of scar contracture despite minimal damage to the ear cartilage when the injury occurred. We have developed a new technique for treatment of a deep burn in the whole ear. METHODS: In the new technique, the ear is amputated, and soft tissues are denuded. The cartilage is banked in a subcutaneous pocket in the chest and later regrafted in combination with costal cartilage. RESULTS: Although techniques for regrafting banked ear cartilage have been reported, the reconstructed ear cannot acquire a good shape because of absorption of the cartilage or lack of intensity to sustain the outline of the ear. Meanwhile, when we tried to reconstruct an ear by only using costal cartilage, we found it difficult to fabricate a frame because most patients are adults in whom the costal cartilage is too rigid and fragile to be shaved or combined. In our technique, the frame has both the advantages of sufficient intensity in costal cartilage and a smooth curved surface together with elasticity in the ear cartilage. Ears reconstructed by our technique have a natural appearance. CONCLUSION: Our technique can be used for cases in which treatment for another large area of the body surface needs to be performed first to save the patient's life.

Full-thickness total upper eyelid reconstruction with a lid switch flap and a reverse superficial temporal artery flap.

BACKGROUND: Reconstruction of the upper eyelid with the same eyelid tissue is desirable because of the ability to achieve eye opening/closing and corneal protection, and a lid switch flap is a useful method. For total defects, almost all of the tissues of the lower eyelid should be used; however, the reconstruction of the lower eyelid donor site has often been undervalued. Reconstruction with an insufficient amount of soft tissue often results in complications such as lagophthalmos and ectropion. Here, we report our method of management of total upper eyelid defects and secondary reconstruction of the lower eyelid donor site. METHOD: A lid switch flap is designed on the lower eyelid as the first operation. As important points, the height of the flap of the anterior lamina should be the same but the conjunctiva as the posterior lamina should be harvested up to the conjunctival fornix to obtain sufficient tissue. After switching the flap, the lower eyelid donor site is reconstructed with sufficient tissue: cheek mucosa, conchal cartilage, and a reverse superficial temporal artery flap as a three-layered structure. RESULTS: Three patients were treated using our method, and we achieved favorable results with a sufficient amount of soft tissue for the reconstruction of the lower eyelid. CONCLUSION: Reconstruction of the upper eyelid with sufficient tissue from the lower eyelid is important for eyelid function.

Establishment of a Standardized Technique for Concha-type Microtia-How to Incorporate the Cartilage Frame into the Remnant Ear.

We have already reported surgical procedures for lobule-type microtia that provide an excellent contour and shape of the ear with minimum sacrifice of the donor. We have succeeded in establishing a standard surgical technique for almost all types of concha-type microtia that effectively uses the remnant ear and can use a unified costal cartilage frame. METHODS AND RESULTS: The concept of our technique is that remnant cartilage should be used maximally but that the deformed area should be completely replaced by the costal cartilage frame. The differences between the cartilage frame for lobule-type microtia and that for concha-type microtia are that the lower half beneath the antihelical area and the concha cymba in the base frame are omitted in concha-type microtia. The area from the tragus to the incisura of the tragus in the antihelical-tragal frame is also omitted. The area of the helical crus in the helical frame and the lower half in the antihelix are not immobilized in the base frame and are free edges. On the other hand, the remnant cartilage outside the concha is removed, but the antitragus is preserved. When the cartilage frame and the remnant are incorporated, all of the components of the ear can be provided. CONCLUSION: The ears created by our technique have a natural appearance and clear contour.

Allopurinol, an inhibitor of uric acid synthesis--can it be used for the treatment of metabolic syndrome and related disorders?

Allopurinol is an inhibitor of xanthine oxidoreductase (XOR) and inhibits the generation of uric acid (UA) as the final product of purine catabolism, as well as the resulting generation of superoxide (O2(-)), in humans. Elevation of the serum UA (SUA) level, referred to as hyperuricemia (HU), eventually leads to gout and allopurinol has been used for the treatment of HU and gout. Studies have revealed the role of elevated SUA levels and the associated oxidative stress (OS) in a broad spectrum of pathological conditions and it is anticipated that these findings would also expand the use of allopurinol as a therapeutic drug. This article presents a review of reports, mainly of recent studies, on the efficacy of allopurinol in various diseases and explores novel potential uses of the drug. Important novel and potential uses of great interest include metabolic syndrome (MetS) and related disorders, chronic kidney disease (CKD), nonalcoholic fatty liver disease (NAFLD) and nonalcoholic steatohepatitis (NASH). Ischemia-reperfusion injury and mucositis, encountered as adverse effects of cancer treatment, have also been under investigation as potential targets for allopurinol.
