Many methods of correcting secondary cleft lip nose deformity have been introduced, but a single best method that can be uniformly adjusted for all cases does not exist. Since it is difficult to make the nostril of the cleft side symmetric with that of normal side, the authors tried to formulate the basis for correction of unilateral secondary cleft lip nose deformity according to the varying amounts of deformed nostril. We then adopted 4 different methods of correcting the soft tissue and nostril deformity in 63 patients from 1996 to 1998 and surveyed the results. Our principles were as follows: 1) Alar rim incision was done in cases of different-shaped cleft-side nostrils with nearly the same measured area in comparison to the normal side. 2) When deformity of the alar-columellar web was severe, we performed modified Z-plasty. 3) When the nostril of the cleft-side nostril was smaller than the normal side with slight asymmetry, reverse W-plasty was done. 4) We adopted a reverse-U incision when there was a discrepancy in height with moderate asymmetry compared with the normal nostril. After dissection, repositioning of alar cartilage was done by same method in each case. A nasal stent was kept in position for at least 6 months postoperatively in almost all cases. After follow-up of 6 to 24 months, we concluded that our choice was correct in selecting the optimal operative method, considering the characteristics of deformity of the cleft side nostril in an effort to make it symmetric with that of the normal side.

A preliminary study was performed to investigate the staining characteristics of trabecula. endothelial cells with low density lipoprotein (LDL) and acetylated low density lipoprotein (Ac-LDL) labeled with a fluorescent probe, 1, 1`- dioctadecyl-3,3,3`, 3`- tetramethyl-indocarbocyanine perchlorate (Dil). Trabecular endothelial cells revealed a strong fluorescence with Dil-LDL, which was contradictory to the previous results obtained from other types of endothelial cells. These cells also showed a moderate fluorescence with Dil-Ac-LDL. Scleral fibroblasts and keratocytes showed a moderate to strong fluorescence with Dil-LDL and a weak fluorescence with Dil-Ac-LDL. Corneal endothelial cells revealed a very weak background fluorescence with Dil-LDL and a moderate fluorescence with Dil-Ar-LDL. Therefore, these four kinds of cells could not be definitely differentiated depending only on the staining characteristics with Dil-LDL and Dil-Ac-LDt.

This experiment used 30 rabbits (40 normal eyes) to determine the applicability of an expanded polytetrafluoroethylene (e-PTFE) surgical membrane as a glaucoma seton. The e-PTFE membrane had 0.1 mm thickness and was cut into T-shaped pieces measuring about 2x7 mm. One end of the implant was introduced into the anterior chamber through a sclerectomy opening and the other ends were allowed to extend from the Iamellar scleral flap into the subconjunctival space. During the follew-up at the end of 8 weeks, all the eyes with an implant showed an apparent filtering bleb, while only one of 6 eyes that had undergone a trabeculectomy alone did. The location of the created filtering blebs depended on the implant position. Pestoperative inflammatory changes were unremarkable. Histologic examinations reyealed a tissue-free cystic space surrounding the e-PTFE implants which maintained their original color, thickness, pliability and size. Transmission electron microscopy showed few myofibroblast-like cells in the fibrous wall containing the implant. With scanning electron microscopy, the internal end of the implant strip had a clean surface and no adhesions to adjacent structures of the anterior chamber angle. The corneal endothelial cells were intact in the area close to the tip of the implant. Considering the clinical and histologic findings, it appeared that the e-PTFE was acceptably innocuous in the anterior segment of the eye and a convenient material as a glaucoma seton.

Purpose: Genu valgum in Legg-Calve-Perthes disease (LCPD) is not a known complication. We investigated whether this valgus tendency is a complication of femoral varus osteotomy (FVO) or the sequela of the disease process itself, and what are the related factors. Materials and Methods: 35 patients treated by FVO and 38 by abduction orthosis (AO) were selected for this study. Only those patients with unilateral involvement, fragmentation stage, Catterall Group III or IV, and who were followed-up to full skeletal maturity were included in the study. We measured mechanical axis deviation percentage and hip-knee-ankle angle for femorotibial alignment, and mechanical lateral distal femoral angle and medial proximal tibial angle (mMPTA) for knee orientation on teleoroentgenograms and compared the affected and normal limbs. Results: All measurements, excluding the mMPTA, demonstrated a tendency of relative genu valgum versus the opposite normal limbs. This tendency was observed in both groups. There was no statistically significant difference between the two groups. Conclusion: Genu valgum occurred in 66% to 70% of the LCPD patients. Four factors were found to be significantly correlated with valgus shift: increased medial bowing of the femoral neck, decreased acetabulum head index, coxa magna, and limb shortening. Multivariate regression analysis identified limb shortening as the factor most responsible for valgus shift.

Background: Hydroxyethyl starch (HES, 6% 130/0.4) has been used as a volume expander for the treatment of cerebral hypoperfusion in acute ischemic stroke. Although HES use was associated with renal failure in sepsis or critical illness, it still remains to be elucidated whether HES is linked to renal adverse events in patients with acute ischemic stroke. Methods: A total of 524 patients with acute ischemic stroke within 7 days of onset were included between January 2012 and May 2016. Renal function on admission and follow-up on day 7 ± 2 was assessed using serum creatinine (SCr) and estimated glomerular filtration rate (eGFR). Propensity score matching (PSM) was used to perform a 1:1 matched-pair analysis to minimize the group differences caused by covariates. The percentage of patients with newonset acute renal injury (AKI) using the Kidney Disease: Improving Global Outcomes or good functional outcome (modified Rankin Scale 0–2) at 90 days were compared between HES cohort and controls. Results: Among the included patients (mean age, 68.6 years; male, 56.5%), 81 patients (15.5%) were HES cohort (median cumulative dose, 1,450 mL). Baseline renal function was better in HES cohort compared to that in the controls (SCr, 0.87 ± 0.43 mg/dL vs. 1.15 ± 1.15 mg/dL, P < 0.001; eGFR, 86.91 ± 24.27 mL/min vs. 74.55 ± 29.58 mL/min, P < 0.001), which became not significant in PSM cohort (72 pairs). The percentage of new-onset AKI did not differ between the HES cohort and controls (1.4% vs. 1.4%, P = 1.000). In addition, newonset AKI was not related to HES (odds ratio, 1.422; 95% confidence interval, 0.072–28.068; P = 0.817) after adjusting for confounders. HES cohort tended to have higher percentage of good functional outcome at 90 days compared to controls, which failed to reach statistical significance (68.1% vs. 54.2%, P = 0.087). Conclusion A low cumulative dose of HES was not associated with renal adverse events in patients with acute ischemic stroke.

PURPOSE: To determine the locations and incidences of sesamoids and accessory bones of the forefoot in normal Korean adults. MATERIALS AND METHODS: The plain radiographs of the forefoot of 400 volunteers, 200 males and 200 females, were taken. The three orthopedic surgeons participated in the radiographic evaluation independently. Persons who had history of foot problem or injury were excluded. RESULTS: Sesamoids of first metatarsophalangeal joint were nearly always present; medial 99% and lateral 100%. The bipartite sesamoid was more common in medial (9.8%) and in female (17.0%) than in lateral (0.3%) and in male (2.5%). Sesamoids of the interphalangeal joint of the first toe were seen in 35.8%. Sesamoids of metatarsophalangeal joints in other four toes were rarely observed. Their incidences were 5% in second toe, 0.8% in third, 0% in fourth, and 2.8% (lateral) and 7.5% (medial) in fifth. Sesamoids of interphalangeal joint in four lesser toes were not observed except two cases (0.5%) in the fifth toe. Accessory bone was very rarely observed. Os vesalianum was observed in five feet (1.3%), Os intermetatarseum in 14 feet (3.5%), and Os cuneo-metatarsal I tibiale in none. CONCLUSION: We determined the location and incidences of sesamoids and accessory bones of the forefoot, and we expected this to help to diagnose the forefoot problem.

PURPOSE: To evaluate the usefulness of total hip arthroplasty with the mini-incision technique (mini-incision THA) by comparing it with conventional THA. MATERIALS AND METHODS: Two groups were compared; one group received conventional THA, the other group mini-incision THA. All these patients were treated using same prosthesis. We compared the postoperative clinical and radiological results. RESULTS: Skin incisions ranging from 13 cm to 28 cm were needed for conventional THA and 5.5-9 cm for mini-incision THA. The mean operative time was 53 minutes for the conventional method and 52 minutes for the mini-incision method. Mean blood loss in mini-incisionTHA was less than in conventional THA by about 240 cc, mean length of hospital stay was shortened by 5 days. Using a 5-point scale, pain was reduced in mini-incision THA. No differences were found between the two groups in terms of the opening angle of the acetabularcomponent and the intramedullary status of the femoral stem insertion. CONCLUSION: Mini-incision THA produced better clinical results and no differences were observed in the radiological findings versus conventional THA. Mini-incision THA is believed to be a useful method of reducing the skin incision and soft tissue dissection, and permits earlyrehabilitation and increases patient satisfaction.

BACKGROUND AND OBJECTIVES: The newly developed 2-dimensional ultrasound speckle tracking imaging (2D-STI) has enabled researchers to assess the changes of left ventricular (LV) rotation and torsion. The aims of the present study are to establish normal values and to examine the effect of advancing age on left ventricular torsion. SUBJECTS AND METHODS: We enrolled 182 healthy persons in this study. After examined the standard clinical echocardiographic parameters, we obtained the degree of the LV rotation at the basal and apical levels of the short axis view with using a customized software program EchoPAC, GE. RESULTS: Among the 182 healthy subjects, 109 healthy subjects were finally included (49 males and 60 females) due to the failure of obtaining reliable rotational patterns (feasibility: 59.8%). The basal and apical peak LV rotations during systole were 8.14+/-3.55 degrees and 8.48+/-3.70 degrees, respectively. The basal peak LV rotation and peak LV torsion had a tendency to increase with aging (r=0.277, p=0.004 and r=0.253, p=0.008, respectively). All the values of the basal LV rotation during systole tended to increase with aging. The apical LV rotation had no relationship with aging throughout the entire cardiac cycle. CONCLUSION: 2D-STI was a feasible methodology to measure the LV rotation. The peak LV torsion during systole shows statistically significant augmentation with advancing age, and this is mainly due to the increased basal LV rotation.
