The relative merits of cartilage scoring versus suturing in techniques for correcting the prominent ear remains a subject of debate among leading plastic surgeons. We compared a variety of echniques for correcting the prominent ear in 72 rabbit ears using scoring, horizontal mattress sutures, and combination scoring and suturing. The ears were splinted with a right-angle fold for 3 postoperative weeks, and the animals were sacrificed after 8 weeks. Suturing techniques in combination with scoring maintained an angulation significantly closer to the desired 90 degrees than cartilage scoring or cartilage suturing only(p<0.05). Histological analysis demonstrated a significant increase in cartilage hyperplasia by suturing alone, whereas the other techniques achieved only mild to moderate increases. We recommend cartilage scoring and suturing through skin incision on severe degrees of prominent ear, and cartilage needle scoring and buried suturing through slit incision on mile-to-moderate degrees of prominent ear.

Pityriasis lichenoides chronica is characterized by unknown etiology, chronicity and by being essentially asymptomatic and refractory to therapy. Nine patients with pityriasis lichenoides chronica were treated with orally administrated 8-Methoxypsoralen and UVA irradiation(PUVA Therapy). After S-45 PUVA treatments, lesions were completely cleared.

Partial trisomy 10q syndrome is a rare chromosome anomaly characterized by severe mental and growth retardation, craniofacial dysmorphia with prominent forehead, fine arched eyebrows, deep set small eyes and micrognathia, In addition, other physical manifestations have been reported as skeletal anomaly, congenital heart disease, inguinal hernia, and so on. We report a case of partial trisomy 10q syndrorne with certain stigmata which confirmed by chromosome analysis.

The incidence of cervical pregnancy and the number of combined intrauterine pregnancy and ectopic pregnancy seems to be increasing. So the possibility of heterotopic pregnancy should always be considered by every gynecologist, especially those who treat infertility problem. We experience a case of a heterotopic pregnancy coexisting of an intrauterine pregnancy and a cervical pregnancy after in-vitro fertilization and embryo transfer, and was successfully managed by transcervical evacuation and resulted in a normal intrauterine pregnancy. Here we present the case with review of literatures.

Most of the peripheral nerve injuries from crushing or compressive forces are accompanied by surrounding soft tissue injuries. As a result, poor vascularity due to fibrosis and sacr formation compromises regeneration of the grafted nerve. Vascularized nerve graft shows superior regeneration to that of a non-vascularized one. However, the human body provides few donor sites of vascularized nerve graft clinically. We presumed that the prefabricated myoneural or adiponeural flap, which include fabricated nerves wrapped with surrounding vascularized muscle or adipose tissue flap, influences superiorly on the regeneration of grafted nerve because that surrounding vasculatity indirectly enhances the vascularity of the grafted nerve itself. Thirty adult male Sprague-Dawley rats were divided into three groups: 1) conventional reversed autogenous graft of the femoral nerve alone(n=10); 2) nerve graft entubulated with abdominal adipose tissue flap with a pedicle of inferior epigastric artery(n=10); 3) nerve graft entubulated with adductor muscle flap with a pedicle of the first muscular branch of the femoral artery(n=10). At three months postoperatively, grafted nerves were examined by electrophysiologic study to check amplitudes and motor nerve conduction velocities, as well as histopathologic study for evaluation of regenerated nerve cells, fibrosis and neo-vascularization. Consquently, nerve regeneration was found in all three groups. Both the myoneural and adiponeural flap groups had better improved results of nerve regeneration compared to that of the conventional nerve graft group. The result of myoneural flap group was superior to that of the adiponeural flap group. The myoneural flap group showed minimal fibrosis and less prominent neovascularization around moderately regenerated nerves. The adiponeural flap group showed more severe perineural and endoneural fibrosis, as well as vascular proliferation around focal regenerated nerves. The results of myoneural flap group proved to be statistically significant. We concluded that it is possible to use nerve graft entubulated with a vascularized muscle flap (myoneural flap) as a substitute for vascularized nerve graft.

Osteoclast-like giant cell tumor of the liver is an extremely rare malignancy with poor prognosis. To our knowledge, 5 cases have been reported in English literatures, but there was no report about fine needle aspiration cytologic(FNAC) features. We experienced a case of osteoclast-like giant cell tumor of the liver obtained by computed tomography(CT)-guided FNAC and needle biopsy. The cytologic findings mimicked giant cell tumor of the bone. A large hepatic mass of the left lobe with abdominal wall invasion was found by CT in a 46- year-old female complaining of epigastric pain. The FNAC showed moderately cellular smears consisting of osteoclast-like giant cells and mononuclear cells, which were individually scattered or intermingled in clusters. The osteoclast-like giant cells had abundant cytoplasms and multiple small round nuclei with fine chromatin and distinct nucleoli. The mononuclear cells had moderate amount of cytoplasm and relatively bland-looking oval nuclei with single small nucleoli. All of the cytologic features recapitulated the histologic findings of bland-looking osteoclast-like multinucleated giant cells evenly dispersed throughout the background of mononuclear cell. The immunohistochemical study showed positive reaction for CD68 and vimentin, but negative for cytokeratin in both osteoclast-like giant cells and mononuclear cells.
