Purpose: This study was performed to calculate and analyze the effective radiation doses from computed tomography (CT) and radiologic intervention in patients in the emergency department (ED) with trauma critical pathway (CP) activation and further to estimate the lifetime attributable risks (LARs) for the incidence of and mortality from cancers induced by the radiation dose. Methods: Through a retrospective electrical chart review of 104 injured patients who trauma critical pathway were activated from November 2012 to March 2013, we calculated effective radiologic doses by taking the product of the dose-linear product of the scan and the conversion coefficient. After a determination of the image results, we divided the patients into two groups, negative or positive, and calculated the effective dose for each group. With these results, we estimated the LARs for the incidence of and the mortality from cancers by using the table in the Biologic Effects of Ionizing Radiation (BEIR)-VII report. Results: A total of 76 patients were enrolled. The mean age was $49.0{\pm}8.5$ years. The mean injury severity score (ISS) was $12.7{\pm}8.4$. The cumulative effective dose (CED) for individual patients varied from 2.8 mSv to 238.8 mSv, and the mean was $47.6{\pm}39.9$ mSv. The CED in patients with an $ISS{\geq}16$($63.2{\pm}26.6$ mSv) was higher than that of patients whose ISS<16($33.5{\pm}23.1$ mSv) (p<0.001). The CED in patients who were treated with surgery or intervention($69.0{\pm}45.2$ mSv) was higher than that of patients who were treated conservatively($33.6{\pm}22.4$ mSv) (p<0.001). The LARs for cancer incidence and mortality were $328.5{\pm}308.6$ and $189.0{\pm}159.3$ per 100,000 people, respectively. Conclusion: The CED and the LAR for trauma CP-activated patients in the ED were significant, so efforts should be made to decrease the effective dose received by severely injured patients.

Oligomeganephronia is a rare congenital form of bilateral renal hypoplasia histologically characterized by reduction in number and hypertrophy of nephrons. Clinically, this condition is presented in early infancy with vomiting, polyuria, polydipsia and dehydration. The problems are readily corrected, but slowly progressive renal failure follows accompanied by failure to thrive, short stature, and renal osteodystrophy. We experienced three cases of oligomeganephronia. Case 1. : A 3 2/12 years old female child was incidentally diagnosed as renal failure at age of 2 months when she was hospitalized due to pneumonia. She had open renal biopsy and was diagnosed as bilateral dysplastic kidney. On OPD follow-up, she progressed to end-stage renal failure (BUN/Cr 114/4.6 mg/dl) and had renal transplantation. The specimen was shrunk remarkably and light microscopy showed oligomeganephronia. Case 2. : A 14 8/12 years old female child with proteinuria was detected in an annual urine screening program for school children, she was diagnosed as renal failure (BUN/Cr 33.9/4.1 mg/dl), and had $5{\times}4{\times}3\;cm$ sized mass on abdominal CT scan. She had renal biopsy, and the specimen showed oligomeganephronia. She had hemodialysis for six months, and renal transplantation along with bilateral nephrectomy was performed. Case 3. : A 14 8/12 years old male child was diagnosed having chronic nephritis and chronic renal failure at 3 years old, progressed to end-stage renal failure (BUN/Cr 87/9.6 mg/dl) on OPD follow-up, and had a rephrectomy and renal transplantation. The biopsy specimen showed oligomeganephronic hypoplasia, secondary focal segmental glomerolosclerosis, and chronic interstitial nephritis. We report 3 cases of oligomeganephronia that progressed to end-stage renal failure and had successful renal transplantation with a brief review of related literatures.

Purpose: Hyoid bone is a U-shaped bone in the anterior of the neck. Hyoid bone fractures are exceedingly rare and represent only 0.002% of all fractures because of its protective position relative to the mandible and its suspension by elastic musculature. We report a patient who presented hyoid bone fracture associated with hypoglossal nerve palsy. We also discuss the possible complication and treatment. Methods: A 69-year-old man was transferred from another institution because of persistent purulent discharge from the left chin. He had a history of trauma in which a knuckle crane grabbed his face and neck in the construction site. A CT scan at the time of the accident demonstrated a comminuted fracture of the right side of the mandible and hyoid bone fracture at the junction between body and right greater cornua. The displaced fracture of hyoid bone and fullness in the pre-epiglottic space were noted, probably indicating some edema. The patient was transferred into ICU after treatment of emergency tracheostomy because the patient showed respiratory distress rapidly. When the patient was hospitalized in our emergency room, he complained of dysphagia and pain when swallowing. On examination of oral cavity, the presence of muscle wasting with fasciculation of the tongue was noted and the tongue deviates to the left side on protruding from the mouth. Pharyngolarygoscopy was performed to make sure that there was no evidence of progressive swelling and pharyngeal laceration. Results: The patient underwent surgical removal of dead and infected tissue from the wound and reconstruction of mandibular bony defect by iliac bone grafting. Hyoid bone fracture was managed conservatively with oral analgesics, soft diet and restricted movement. Hypoglossal nerve palsy was resolved within 7 weeks after trauma without complications. Conclusion: Closed hyoid bone fracture is usually uncomplicated and thus it can be treated conservatively. Surgical intervention for hyoid bone fracture is recommended for patient with airway compromise, pharyngeal perforation and painful symptoms which show no response to conservative care. Furthermore, since respiratory distress syndrome may develop quickly, close observation is required. Besides, hypoglossal nerve palsy is a rarely recognized complication of hyoid bone fracture.

Clinical observation was done on 1092 cases of cerebrovascular disease which were confirmed by Brain CT scan in Oriental Medical Hospital in Kyung Hee Univ. from May 1987 to May 1988. Specially, clinical prognosis of 250 patients who had been hospitalized for over 4 weeks, were obserbed. The results were obtained as follows; 1. In this study, Occlusive CVD was 77.9%, Cerebral hemorrhage was 18.8%, Subarachnoid hemonhage was 0.8%. 2. The ratio of male to female was 1.4:1. In the age distribution, 60th decade, 50th decade, 40th decade, 30th's, 20th's were in order of frequency and specially 60th decade was 35.53% over 70th decade was 17.1% in ratio. 3. The most common preceding disease of CVD was hypertension (54.21%) and diabetes mellitus (19.96%) was second. 4. Almost, the duration of hospitalization was 2-4 weeks in 34.8%, within 4 weeks in 78.02%. 5. Primary attack was 75.7%, 2nd attack was 17.9%, over 3rd attack was 3.1% in ratio of recurrence. 6. The level of consciousness was Grade I in 96.4%, Grade II in 3.2%, Grade III in 1% at attack. 7. A few complications of C.V.A. were observed in the studies: pneumonia was noted frequently in 3.2%, bed sore, urinary tract infection, gastro intestinal bleeding in order of frequency. 8. The ratio of neurologic deficiency in occlusive CVD decreased from 51.9% to 29.3% in upper limb, 52.6% to 24.4% in lower limb, and that in cerebral hemorrhage decreased from 69.5% to 25% in upper limb, 50% to 20% in lower limb. 9. The ratio of left side hemiplegia to right was 1.04:1 in male, 1:1.18 in female. 10. The herb medications for C.V.A. were various Chungg-Paesagantang, Sunghanggeonggisan were used most frequently to Chungyeold, Geopung, Soongi, Haldam and Chungsimtang, the drugs for Bogiheol were used as discharge. In these oriental medical therapy of C.V.A. objective diagnosis and more various therapeutic method must be obtained through east-west medical co-operation.

자궁내막 증식증은 일차적으로 골반내에 국한된 질환이나 드물게 폐실질에서 발견될 수 있다. 폐 자궁내막 증식증의 진단은 임상적 양상과 월경기간 동안의 객혈이 있으면서 조직학적 확진을 통해서 진단될 수 있다. 폐 자궁내막 증식증은 1956 년 Lattes등에 의해 처음으로 조직학적으로 확진한 후에 전세계적으로 드물게 보고되고 있다. 저자들은 25세 미혼 여성에게서 월경과 연관된 객혈을 한 여성에게서 흉부 전산화 단층촬영과 기관지 내시경을 통해서 병소를 확인한 후에 수술적 치료를 함으로 조직학적으로 확진한 폐실질 자궁내막 증식증 1예를 보고하는 바이다.

관상동맥-폐동맥 누공은 비교적 드문 질환으로 선천적 원인이 대부분이나 최근 흉부 시술이나 방사선 치료의 증가로 점차 후천적 원인이 많아지는 추세이다. 증상이 비특이적이어서 진단이 늦어질 수 있어 주의를 요한다. 저자들이 경험한 환자는 기존의 폐질환 증상 때문에 심장 혈관 질환의 진행을 예측하기 어려웠다. 약간의 논쟁이 있으나 원인에 계 없이 크기가 작은 누공에서는 추적관찰이, 중등도 이상의 크기이거나 확장 가능성이 있는 경우에는 누공을 막거나 원인혈관을 제거하는 방법이 장되고 있다. 예후는 대체로 양호한 편이다.

기관 내 사구 종양은 매우 드문 종양이며 일반적인 사구 종양의 증상을 보이지 않다가 크기가 커진 이후에 호흡 곤란이나 객혈, 기침 등의 비특이적인 증상을 보이기 때문에 진단 및 치료가 지연될 수 있다. 따라서 비특이적인 호흡기 증상을 지속적으로 호소하는 환자의 경우 흉부 전산화단층촬영 및 기관지 내시경 등의 적극적인 검사가 필요할 것으로 사료된다. 본 저자들은 호흡 곤란을 주소로 내원한 58세 남자 환자에서 상부 기관 후벽에 발생한 사구 종양 1예를 경험하였기에 이에 대한 문헌 고찰과 함께 보고하는 바이다.
