Purpose: To evaluate therapeutic effects and usefulness of a combination treatment of intravitreal injection of triamcinolone acetonide (IVTA) and panretinal photocoagulation (PRP) in patients with clinically significant macular edema secondary to proliferative diabetic retinopathy (PDR). Methods: Visual acuity test, fundoscopy, fluorescein angiography, and optical coherence tomography (OCT) were taken in 20 patients (20 eyes) of macular edema and PDR. A combination of intravitreal injection of triamcinolone acetonide and PRP was performed in 10 patients (10 eyes) and a combination of focal or grid laser photocoaqulation and PRP in the remaining 10 eyes. The postoperative outcomes were compared between the two combination treatments by best corrected visual acuity (BCVA), tonometry, fluorescein angiography, and OCT at 2 weeks, 1, 2, and 3 months. Results: Average BCVA (log MAR) significantly improved from preoperative 0.56±0.20 to 0.43±0.08 at 1 month (P=0.042) and it was maintained until 3 months after a combination of IVTA and PRP in 10 eyes (P=0.007). The thickness of fovea decreased from average 433.3±114.9 μm to average 279.5±34.1 μm at 2 weeks after combined treatment of IVTA and PRP (P=0.005), which was significantly maintained until 3 months, but there was a transient visual disturbance and no significant difference in thickness of the fovea before and after treatment in the groups with PRP and focal or grid laser photocoagulation. Conclusions: A combination of IVTA and PRP might be an effective treatment modality in the treatment of macular edema and PDR and prevent the subsequent PRP-induced macular edema result in visual dysfunction. In combination with PRP, IVTA might be more effective than focal or grid laser photocoagulation and PRP for reducing diabetic macular edema and preventing aggravation of macular edema without transient visual disturbance in patients requiring immediate PRP.

목적 : 초음파 기기의 발달로 임신 중의 태아 임신 주수에 따른 발육 상태를 태아의 아두 대횡경, 대퇴골 길이, 복부 둘레 등을 측정함으로써 예측할 수 있게 되었다. 그러나 아직 정확한 한국의 태아 신체 각 부분의 평균 표준치가 없다는 것은 빨리 해결해야 할 과제라 생각된다. 따라서 본 연구는 정상 태아의 평균치 및 제태 연령을 예측할 수 있는 회귀 방정식을 구하고자 하였다. 연구 방법 : 1996년 6월부터 1998년 3월까지 삼성제일병원에서 산전 검사를 받은 300명의 산모 중, 태아 성장에 영향을 줄 수 있는 요인을 가진 29명을 제외한 총 271명의 산모를 대상으로 하였다. 이들에서 태아의 전둔장 (CRL), 아두 대횡경 (BPD), 머리 둘레 (HC), 복부 둘레 (AC), 대퇴골 길이 (HL), 경골 길이 (TL)를 측정하였으며, 제태 연령을 예측하는 회귀 방정식은 선형 회귀 분석을 통해 구하였다. 결과 : 임신 11주에서 29주 사이의 태아의 전둔장, 아두 대횡경, 머리 둘레, 복부 둘레, 대퇴골 길이, 경골 길이의 백분율을 산출하였으며, 제태 연령을 예측하는 이차 방정식을 추론하였다. 결론 : 본 연구는 정상 태아의 생체 계측의 평균치 및 백분율을 구하였다. 많은 수의 산모를 전향적으로 측정하였고, 측정자 수를 제한함으로써 계측자간의 오차를 최소화하였다. 또한 한국 태아의 경골의 평균치 및 백분율을 처음으로 산출함으로써 임신 연령 측정에 좀더 정확한 자료를 제시하였다. Objective : The purpose of this study was to assess the mean fetal biometry and to create a formulae for estimation of gestational week using sonographic biometry measurement. Methods : A total 271 women of singleton gestation were involved in this study of ultrasonographic fetal biometry. During the period from June 1996 to March 1998, the length of CRL (Crown Rump Length), BPD (Biparietal Diameter), HC (Head Circumference), AC (Abdominal Circumference), HL (Humerus Length) and TL (Tibia Length) of fetuses in normal pregnancy were measured by ultrasonography at Samsung Cheil Hospital & Women`s Healthcare Center. The gestational age prediction equations were derived form sigletons with the use of liner regression analysis. Results : We present the percentile ranks of fetal CRL, BPD, HC, AC, HL and TL measurement from 11 to 39 week`s gestation and mean value of fetal size at each week. These data were analyzed and several second grade equations were derived from the data. Conclusion : We created these authentic equations and tables for mean value of fetal biometry in normal pregnancy at each gestation week with minimal intervariable errors.

Osteoradionecrosis is one of the most serious complications of patients receiving radiation therapy. It is characterized by hypovascularity, hypocellularity, and hypoxia-inducing necrosis of bone and soft tissue following delayed healing. In this case, a 72-year-old man was referred to the Department of Oral and Maxillofacial Surgery complaining of trismus following extraction three months before first visit. He had a history of right tonsillectomy, radical neck dissection and radiotherapy performed due to right tonsillar cancer seven years prior. After the diagnosis of osteoradionecrosis on right mandibular body and angle, conservative antibiotic therapy was used first, but an orocutaneous fistula gradually formed, and extensive bony destruction and sequestrum were observed. Sequestrectomy, free particulated iliac bone and umbilical fat pad graft were performed via a submandibular approach under general anesthesia. Preoperative regular exams and delicate wound care led to secondary healing of the wound without vascularized free flap reconstruction.
