목적: 부인과 수술 합병증으로 발생한 비뇨기계 손상에 대한 산부인과 의사에 의한 복원술에 있어 복강경 수술의 가능성과 유용성을 보고자 하였다. 연구방법: 2003년 3월부터 2010년 2월까지 성균관대학교 의과대학 강북삼성병원 산부인과학교실에서 부인과 수술 합병증으로 발생한 비뇨기계 손상에 대한 복강경 수술을 받은 총 38명의 환자들의 의무기록을 후향적으로 분석하였다. 비뇨기계 질환으로 복강경 수술을 받은 환자들의 연령, 분만력, 체질량지수(body mass index), 복부 수술력, 비뇨기계 손상의 종류, 시행된 복원 술기, 복원술 후 임상경과를 분석하였다. 결과: 총 38예의 비뇨기계 손상 중, 27예가 방광손상이었고, 6예가 요관질누공 1예를 포함한 요관손상이었으며, 5예가 방광-질누공이었다. 환자 나이의 중앙값은 45세(범위, 31-77세), 분만 횟수의 중앙값은 2회(범위, 0-4회), 체질량지수 중앙값은 21.4 kg/m2 (범위, 18.8-31.4 kg/m2), 이전 복부수술 횟수 중앙값은 1회(범위, 0-3회)이었다. 추적관찰 기간은 39개월(범위, 16-78개월)이었다. 모든 환자에서 개복술로의 전환 없이 복강경을 통해 성공적인 복원술이 시행되었다. 복원술 이후 추적관찰 기간 동안 합병증은 발생하지 않았다. 결론: 부인과 수술과 관련된 비뇨기계 손상에 대하여 숙련된 부인과 수술팀의 복강경을 이용한 복원술로 성공적인 수술적 처치가 가능하다. Objective: To assess efficacy and feasibility of laparoscopic surgery for genitourinary tract injuries related with gynecological surgery. Methods: We conducted a retrospective study of 38 patients undergoing laparoscopic surgery to treat genitourinary tract injury which occurred during gynecologic surgery in Kangbuk Samsung Hospital from March 2003 to February 2010. We analyzed the demographic and clinical characteristics including history of previous abdominal surgery, the type of injury, type of repair procedure, and any complications. Results: Of the 38 patients, 27 had urinary bladder injury, six had ureter injury including ureterovaginal fistula in one, and five had vesicovaginal fistula. The median age of patients, the median body mass index, and the median follow-up period were 45 years (31 to 71 years), 21.4 kg/m2 (18.8 to 31.4 kg/m2), and 39 months (16 to 78 months), respectively. There were no laparoconversions. No intraoperative or postoperative complications occurred. All patients have been asymptomatic, and their follow-up intravenous pyelograms and ultrasound examinations have been normal. Conclusion: Laparoscopic repair of genitourinary tract injuries occurred during gynecologic surgery is feasible for experienced laparoscopic surgical team in gynecology.

목적: 본 연구는 배꼽을 통한 단일공 복강경하 자궁외 임신 수술의 방법, 유용성과 안전성을 평가하기 위함이다. 연구 방법: 2009년 10월부터 2010년 2월까지 울산대학교병원 산부인과에서 자궁외 임신으로 단일공 복강경 수술을 시행 받은 총 6명의 환자들의 의무기록지를 후향적 연구 방법으로 분석하였다. 결과: 환자의 나이의 중앙값은 33.5세 (범위, 32~36)였고 BMI의 중앙값은 20.6 kg/m2 (범위, 16.5~28.7)이었다. 자궁외 임신낭의 가장 큰 직경의 중앙값은 4.8 cm (범위, 3.0~5.4)이었고 모든 환자에서 임신낭 파열과 복강내 출혈을 보였다. 수술에 소요시간의 중앙값은 77.5분 (범위, 59~95)이었고, 수술 중 실혈량의 중앙값은 40 mL (범위, 20~50)이었다. 수술 후 재원 기간의 중앙값은 2일 (범위, 1~3)이었고, 재원기간과 마지막 추적 관찰 기간 동안에 합병증이 발생한 경우는 없었다. 결론: 배꼽을 통한 단일공 복강경하 자궁외 임신 수술은 자궁외 임신 치료에서 안전하고 유용하였고, 기존 다공법 복강경하 수술에 대안이 될 가능성이 있다. Objective: To evaluate the effectiveness of transumbilical single-port access laparoscopic surgery of ectopic pregnancy. Methods: Retrospective analysis was performed on six patients who underwent transumbilical single-port access laparoscopic management of ectopic pregnancies. Results: The median age of 6 cases was 33.5 years (range, 32 to 36), and the median body mass index was 20.6 kg/m2 (range, 16.5 to 28.7). The median largest diameter of G-sac was 4.8 cm (range, 3.0 to 5.4). Intracorporeal rupture and hemoperitoneum were accompanied in all cases. The median time needed for the surgery was 77.5 minutes (range, 59 to 95). The median estimated blood loss was 40 mL (range, 20 to 50). The median postoperative hospital day was 2 days (range, 1 to 3). There were no complications on postoperative course and follow-up. Conclusion: Transumbilical single-port access laparoscopic surgery for ectopic pregnancy was feasible and safe. This approach might be reasonable alternative to conventional laparoscopic surgery using 3 or 4 port in the management of ectopic pregnancy.

넓은 입력전압 범위를 갖는 게이트 드라이브용 Charge Pump Voltage Regulator

엄정민(Jeong-min Eom),김채원(Chai-won Kim),차영민(Young-min Cha) 대한전자공학회 2023 대한전자공학회 학술대회 Vol.2023 No.6

This paper proposes a voltage source design to operate the Vgs of the power transistor of the motor driver IC at 13V. The voltage source drives the low-side and charges the bootstrap capacitor. At this time, the target voltage is sufficient to drive the Power Transistor even at a low input voltage, and even at a high input voltage, a stable voltage source is generated with low ripple and high efficiency. It is expected to be used in various applications because a constant 13V voltage source is created at a very wide input voltage of 5.5V-50V through a combination of charge pump, regulator, switch, etc.

A 28-year-old primi gravida visited our department at 20 weeks gestation. The ultrasound screening revealed twin gestation, and follow up screening revealed a bilobed large fetal neck mass in the 1st twin. We measured thyroid volume with ultrasound which was 5.072 cm3. Other fetal organs appeared normal. Cordocentesis was performed for fetal thyroid function and congenital hypothyroidism was confirmed. In addition, maternal thyroid hormones were checked. The other fetus was normal. Thyroid stimulating hormone (TSH) in the maternal serum was increased, but thyroxine (T3) was (within normal range). Two weeks later, we checked TSH and free T4 in amniotic fluid and administered intra-amniotic thyroxine (200 μg). We repeated the procedures 2 more times in two consecutive weeks. After 3 intra-amniotic thyroxine injection, follow-up cordocentesis revealed euthyroid status of the fetus. Although the thyroid gland had decreased in size and volume, it was still goitrous. At 36 weeks of gestation, the patient was admitted for preterm premature rupture of the membranes and the twin was delivered vaginally. The 1st twin was proved as an euthyroid status and antithyroid antibody was not detected. During the 3 years follow up, the baby had no considerable developmental problem. The intrauterine recognition and treatment of congenital goitrous hypothyroidism may not only reduce the obstetric complications associated with large goiters, but possibly improve the prognosis for normal growth and mental development of affected fetuses.

고혈압성 뇌병증은 고혈압 환자에서 고혈압과 관련된 두통, 경련, 시각장애 및 다른 신경학적 장애를 동반하는 증후군이다. 증례는 13세 여자환아로 급성 연쇄상구균 감염후 사구체 신염에 동반된 고혈압성 뇌병증 환자였다. 내원시 혈압은 150/110 mmHg 였고 내원당시 검사소견상 단백뇨, 혈뇨, C3의 감소 소견을 보였다. 내원 2일째 자기공명영상을 시행하였고 스핀에코 T2 강조영상에서 양 후두엽과 후 측두엽에 고신호의 이상 부위들이 발견되었다. 치료후 실시한 자기공명영상은 정상 소견을 보였다. 본 저자들은 급성 사구체 신염 환자에서 자기공명영상으로 고혈압성 뇌병증을 진단하고 치료한 1례를 문헌고찰과 함께 보고하는 바이다. Hypertensive encephalopathy is a syndrome consisting of headache, seizures, visual changes, and other neurologic disturbances in patients with elevated systemic blood pressure. We experienced a 13-year-old girl who presented with the manifestations of hypertensive encephalopathy in acute post-streptococcal glomerulonephritis. She visited our hospital because of generalized tonic-clonic seizure after severe headache. On admission her blood pressure was 150/110 mmHg and initial laboratory findings revealed proteinuria, hematuria and decreased C3 level and, T2-weighted MR image showed increased T2 signal in both occipital lobes, suggesting cerebral edema. On follow-up MRI, pathologic lesions were improved. We described a case of hypertensive encephalopathy in acute post-streptococcal glomerulonephritis diagnosed by MRI with a brief review of some related literatures.
