        임부상해의 병리

        大韓法醫學會 1986 대한법의학회지 Vol.10 No.2

        Pregnancy is associated with marked physiologic and anatomic changes in nearly every organ system of the body. Although these alterations are normal and necessary to meet the needs of the developing fetus and prepare the mother for parturition, their manifestations may resemble changes that in the nonpregnant woman would be indicative of pathologic states. Furthermore, the altered physiologic and anatomic relationships may change the pattern of injury or disease, and in many instances necessitate modifications in therapy. The purpose of this lecture is to review the anatomic and physiologic changes which the physician must understand to properly care for the traumatized pregnant woman.

        Miller­Fisher 증후군 환자에서의 정기적인 안과 검사 결과

        김범기(Bumgi Kim) (Jin Cho) 대한검안학회 2018 Annals of optometry and contact lens Vol.17 No.2

        Purpose: To investigate the clinical features of Miller-Fisher syndrome patients based on ophthalmologic examination. Methods: We retrospectively analyzed the medical records of patients diagnosed with Miller-Fisher syndrome at Sanggye Paik hospital from January 2011 to December 2016. We investigated the type of strabismus, angle of deviation, ocular motility disorder, anti-GQ1b antibody positivity, brain magnetic resonance imaging, cerebrospinal fluid examination, accompanying clinical features, and accompanying signs of Miller-Fisher syndrome. We analyzed and compared duration of the disease according to the type of the preceding infection, the presence of pupil involvement and ptosis, the presence of three signs in Miller-Fisher syndrome, and the treatment modalities. Results: A total of 12 patients were included. Eight men (67%) and four women (33%) were enrolled. Six patients (50%) had symptoms of respiratory infection and four patients (33%) had symptoms of gastrointestinal infection before the onset of ophthalmoplegia. Ophthalmoplegia was lateral rectus muscle palsy in 100 %, medial rectus muscle palsy in 75.0%, superior rectus muscle palsy in 58.3%, and inferior rectus muscle palsy in 50.0% of patients. 100% of patients showed esotropia and 58.3% showed esotropia with vertical strabismus. In three patients (25%), a typical Miller-Fisher syndrome that had all the signs of Miller-Fisher syndrome was present. There was no statistically significant difference in the duration of the disease, depending on the type of the preceding infection, the presence of pupil involvement, the presence of ptosis, the presence of three signs in Miller-Fisher syndrome, and treatment modalities. Conclusions: Miller-Fisher syndrome is characterized by paralysis of the horizontal extraocular muscles, accompanied by symptoms such as pupil abnormalities and ptosis. There was no effect on the duration of the disease according to the type of preceding infection, the presence of pupil involvement and ptosis, the presence of three signs in Miller-Fisher syndrome, and the treatment modalities.

      • 10년간 마취예에 관한 임상적 관찰

        현 만,,이 정 웅 慶北大學校 醫科大學 1976 慶北醫大誌 Vol.17 No.1

        1966년 1월부터 1975년 12월까지 경북대학교 의과대학 부속병원 수술실에서 시행된 마취총수 12,471예를 통계적으로 관찰하여 다음과 같은 결과를 얻었다. 전신마취가 국소마취나 척추마취에 비해서 매년 증가하는 경향을 보였고 년령별로는 21세에서 40세까지 환자가 전체의 약 반수를 차지하였으며 마취 총수 중에서 거의 대부분이 일반외과 정형외과 신경외과 산부인과의 수술이 였으며 환자의 수가 매년 증가 했음을 알 수 있고 특히 응급환자의 수가 현저한 증가를 보였으며 노인마취나 소아마취도 매년 점차로 증가하는 양상을 보였다. 일년중 9월과 10월에 환자가 가장 많은 경향을 보였다. In a total of 12,471 cases anesthetised at the Kyoungpook National University hospital from January 1966 to December 1975 was studied. They were analyzed according to age, sex, surgical section, by month, year, and anesthetic method. Recently, general anesthesia has been used with increasing frequency, while the use of spinal and local anesthsia has decreased. More than half of the total anestheitc cases were for the patients in 2nd and 3rd decade of their ages. Almost all of the total anestheitc cases were general surgery, neurosurgery, orthopedic surgery, obstetric and gynecologic surgery, Numbers of surgery patients and emergency operations increased yearly and also the numbers of cases of geriatric and infant operations increased remarkably. There are more operative patients in the months of September and October than in other months of year.

        수소 저장 탱크용 고압 밸브의 개도율에 따른 열·유동 특성 분석

        정다운, ,서현규 한국수소및신에너지학회 2022 한국수소 및 신에너지학회논문집 Vol.33 No.5

        In this study, in order to numerically analyze the heat flow characteristics in the valve according to the opening rate for the solenoid valve for hydrogen supply applied to the hydrogen storage tank, flow characteristics were comparatively analyzed. Through the analysis of pressure and temperature distributions within the valve according to the high-pressure supply condition of 70 MPa or more, the heat flow characteristics in the valve, inlet and outlet passage according to the opening rate of the valve were identified. As a result a sudden change in the fluid behavior appears in the neck region of the valve, and it is understood that the flow separation caused by the flow path shape of the expanded tube has a dominant influence on the flow characteristics. And, it was confirmed that the shape of the valve seat is a factor significantly affecting the improvement of flow rate and differential pressure performance.

        편두통이 있는 소아에서 빛간섭단층촬영을 이용한 시신경유두 주위 망막신경섬유층 두께 분석

        심하은,유수정, 대한안과학회 2023 대한안과학회지 Vol.64 No.10

        목적: 편두통이 있는 소아에서 동반된 시각적인 전조 증상에 따른 시신경유두 주위 망막신경섬유층 두께의 차이를 빛간섭단층촬영을이용하여 분석하고자 한다. 대상과 방법: 본 연구는 기질적인 질환이 없는 편두통 환아들과 정상 대조군 소아를 대상으로 빛간섭단층촬영을 이용하여 시신경유두주위 망막신경섬유층 두께를 측정하였으며, 시각적 전조 증상의 유무와 양상에 따른 차이도 함께 분석하였다. 또한 편두통의 기간, 지속 시간, 빈도가 망막시신경섬유층 두께에 미치는 영향을 함께 분석하였다. 결과: 본 연구에는 편두통 환아 45명과 대조군 30명이 포함되었다. 편두통 환아 중 시각적 전조 증상을 호소한 환아는 15명, 시각적인전조 증상이 없는 환아는 30명이었다. 시각적 전조 증상 중 시각 흐림 및 암점이 있었던 환아는 7명, 섬광 증상을 호소한 환아는8명이었다. 시신경유두 주위 망막신경섬유층 두께의 비교는 시각 흐림 및 암점을 호소한 환아에서 대조군, 전조 증상이 없는 환아, 섬광 증상을 호소한 환아보다 전체 시신경유두 주위 망막신경섬유층 평균 두께가 유의미하게 얇게 나타났다(p<0.05). 또한 두통의지속 시간과 빈도가 전체 시신경유두 주위 망막신경섬유층 두께와 음의 상관관계를 보였다(r=-0.782, p=0.022). 결론: 시각 흐림 및 암점의 전조 증상을 호소한 편두통 환아에서 시신경유두 주위 망막신경섬유층 두께가 유의하게 얇은 것으로 나타났다. Purpose: We investigated disparities in retinal nerve fiber layer (RNFL) thickness surrounding the optic disc among pediatric migraine patients based on the presence of a concomitant visual aura. Methods: We used optical coherence tomography to measure RNFL thickness around the optic disc in children with migraines and no organic diseases, along with a control group of healthy children. Differences in RNFL thickness were analyzed based on the pattern of prognostic symptoms. Additionally, we investigated the effects of migraine duration and frequency on RNFL thickness. Results: In total, 45 children with migraine and 30 healthy controls were enrolled in this study. Among the children with migraine, 15 experienced visual aura, whereas 30 did not exhibit visual aura. Visual prognostic symptoms included blurred vision, scotoma, and scintillating scotoma. Seven children presented with blurred vision and scotoma, whereas eight reported scintillating scotomas. The mean RNFL thickness around the optic disc was significantly lower in patients with blurred vision and scotomas (89.19 ± 7.99 μm) compared with the control group (98.79 ± 8.49 μm), patients without visual aura (100.55 ± 6.43 μm), and patients with scintillating scotoma (102.21 ± 10.13 μm, p < 0.05). Conclusions: RNFL thickness around the optic disc was significantly reduced in children with migraine who reported symptoms of blurred vision and scotoma.

        미숙아망막병증이 없는 미숙아에서 RETevalTM을 이용한 망막전위도 평가

        정경도,박재용,박지민,김재석, ,황제형 한국망막학회 2022 Journal of Retina Vol.7 No.2

        Purpose: This study was to conducted to evaluate the usefulness of light adapted electroretinography (ERG) using the RETevalTM system (LKC Technologies, Gaithersburg, MD, USA) in preterm infants without retinopathy of prematurity. Methods: Overall, 18 preterm infants underwent light adapted ERG using the RETevalTM system without sedation. Readable results were acquired from 11 patients (61%) and the mean gestational age at birth was 33 ± 3 weeks. Results: The amplitude and implicit time of the ‘a’ wave was -8.1 ± 6.6 μV and 17.3 ± 7.8 ms, respectively, while those of the ‘b’ wave was 20.4 ± 13.6 μV and 36.7 ± 8.8 ms, respectively. Additionally, 30-Hz flicker results were obtained with an amplitude and implicit time of 6.0 ± 3.8 μV and 32.3 ± 2.8 ms, respectively. Negative correlation was found between the ‘a’ wave amplitude and age at examination (p < 0.05). The light-adapted 3.0 ERG response was decreased in preterm infants and a larger decrease in ‘b’ wave amplitude than ‘a’ wave amplitude was observed, which corresponds to the histological maturation of the retina. Conclusions: Our study indicates that RETevalTM system is useful for evaluating retinal function in preterm infants.
