Island flaps have been widely used for the management of soft tissue defects in reconstructive surgery. The necrosis of the flap has been a catastrophe in clinical fields. It is well known that revascularization to the flap after ligation of its pedicle comes from the recipient bed and flap margins. The authors investigated the effects of the ischemic recipient bed on island flap survival after the ligation of its pedicle in the rats. One hundred and thirty inferior epigastric island flaps were divided into three groups (Group I, Group II, and Group III) according to the degree (0%,20%, and 60%) of interruption of contact of flap with the recipient bed, respectively. In Group I,the vascular pedicles were ligated before and on the 0, 2nd, 3rd, 4th and 5th days after flap elevation, and in Group II & III, the vascular pedicles were ligated on the 2nd, 3rd, 4th and 5th days after flap elevation. Flap survival was assessed on the 3rd day after pedicle ligation. Microangiographic studies were also performed on the 3rd day after pedicle ligation to study revascularization within the flap and the change of blood vessels around the flap margins. The results were as follows: 1. Flap survival was increased significantly in the flaps with pedicle ligation on the 4th and 5th postoperative days compared to those at the 2nd and 3rd postoperative days. 2. From the 3rd postoperative day, flap survival was not influenced significantly by the degree of limited bed contact and the date of pedicle ligation. 3. In spite of limited bed contact, the flap will likely survive with abundant revascularization from the flap margins. In conclusion, the flaps with limited bed contact were revascularized significantly from the flap margin by the 3rd postoperative day.

A 72-year-old woman developed pruritic erythematous patches on sun-exposed areas for 2 months following treatment with hydrochlorothiazide (Dichlozid) for hypertension. A phototest revealed a decreased minimal erythemal dose to UVA (MED(UVA)=2 J/cm²). A photopatch test with 0.5%, 1%, and 5% hydrochlorothiazide ointment revealed no response. Two weeks after discontinuation of hydrochlorothiazide, the skin lesions improved with complete loss of photosensitivity without any therapy. At that time, an oral provocation phototest with hydrochlorothiazide was performed and it showed a decreased MED to UVA (MED(UVA)=2 J/cm²).

Macrostomia is a relatively rare malformation. There have been many surgical methods for the correction of macrostomia. The old method, a simple straight line closure , did not include reconstruction of the orbicularis oris muscle. Postoperatively, a depressed scar and severe contraction on the cheek were found, especially with animation. As a result, many authors have known that reconstruction of the orbicularis oris muscle was very important to avoid a depressed scar for the correction of macrostomia. The tendency toward lateral displacement of the reconstructed commissure has been attributed to linear scar contraction, and Z-plasty is advocated to prevent this deformity. However, we found that the Z-plasty scar may be conspicuous when the patient smiles. So we performed reconstruction of the orbicularis oris muscle to avoid a depressed scar, and straight line closure to avoid a conspicuous scar. In order to prevent linear scar contracture due to straight line closure, we overcorrected the new commissure. We treated 6 cases of macrostomia form May 1, 1996 to April 30, 1999 using straight line closure and reconstruction of the orbicularis oris muscle. Periods of follow-up were from 12 months to 35 months, with an average of 20,2 months. Every patient was analyzed clinically by ordinary scale method and anthropometrically by the ratio of abnormal distances to normal distances between cheilion and crista philtri. In 3 clinical assessments : symmetry of the commissure was excellent: degree of the scar at rest was good: and degree of depression with animation was excellent. The anthropometrical ratio was 1:1.05. Despite the fact that the linear scars were perpendicular to the minimal skin tension lines, the scars were inconspicuous. The muscle repair provided reconstruction to the modiolus and gave a natural appearance to the commissure, however it did not seem to provide sufficient bulkiness around the commissure. The straight line skin closure and repair of the orbicularis oris muscle provide effective functional and aesthetic reconstruction.

A patient with extraskeletal cervical epidural Ewing's sarcoma who presented with cervical radiculopathy is reported. A 58-year-old woman presented with right posterolateral neck pain and upper extremity radiculopathy. The computed tomography myelography showed epidural and paravertebral masses on right side, with widening of the ipsilateral neural foramina at the C2-C3 level. On magnetic resonance images, the mass was isointense to soft tissue on T1-weighted images, hyperintense on T2-weighted images, and showed diffuse enhancement on GdTA enhanced T1-weighted images. The staged, combined posterior and anterior approach were done and the tumor mass was subtotally removed. During postoperative adjuvant chemotherapy with Cytoxane, Adriamycin, Vincristine, Prednisolone regimen, the patient died of severe compression of upper cervical cord by recurrent, extended tumor mass in the spinal canal.

BACKGROUND: Longer RBC storage will benefit blood banker by reduced outdating and patients by receiving fewer nonviable cells and RBC breakdown products as well as by having the opportunity to participate in markedly improved autologous storage system. METHODS: We rejuvenated whole blood 10 units and RBC 15 units, on 1-3 days after expiration, then they were divided into four, washed, and suspended with four kinds of solutions containing saline adenine glucose, mannitol, and phosphate, in closed system. For the evaluation of RBCs, 30 min saline stability (SS), 2 h SS, % hemolysis, ATP, 2,3-DPG, P50, LDH, potassium, and plasma hemoglobin were tested at every week during 42 days. RESULTS: On 35th day, 30 min SS of RBCs was higher than 88% and % hemolysis of RBCs was lower than 1% in solutions containing phosphate. ATP of RBCs was the 50% of the reference value of healthy persons and 2,3-DPG of RBCs was relatively higher in solutions containing phosphate (SAGMP1, 2, 3) than in solution without phosphate (SAGM). CONCLUSION: We could successfully rejuvenate outdated RBCs and extend the expiration date to additive 35 days, but for practical use, post transfusion RBC survival and safety should be evaluated in the future.
