최근 조사에 따르면 당뇨병 발병 10년을 기점으로 실명위험이 높아지는 것으로 분석됐다. 그 원인은 당뇨망막병증 때문. 대한안과학회가 지난 1년간 조사한 결과 당뇨병이 발병한 지 10년 이하의 환자들은 눈질환이 나타나지 않거나(25%), 비교적 실명위험이 적은 비증석성 당뇨망막병증(45%)이 발견됐다. 하지만 11년부터는 당뇨망막병증의 발생이 급격히 증가해 20년이 넘으면 최대 72%까지 그 위험성이 높아진다. 당뇨망막병증은 일단 발생하면 혈당조절이 잘 돼도 시력이 만힝 손상되고 교정도 힘들어 당뇨병에 걸리면 초기부터 안과진료를 받아 실명 위험을 줄여야한다. 이에 공안과에서 당부하는 당뇨망막병증에 관한 내용을 판화를 통해 쉽게 이해해보고자 한다.

당뇨가 오래되면 삶의 질을 떨어뜨리는 여러 가지 합병증들이 오게 되는데 그 중에서 시력을 위협하는 제일 심각한 합병증은 당뇨망막병증으로 이는 망막에 영양을 공급하는 혈관이상에 의해 발생하는 진행성 질환이다. 당뇨망막병증의 발생빈도는 당뇨의 유병기간과 밀접한 관계가 있다. 당뇨로 진단받고 5$\sim$10년이 지나면 25$\sim$50%가 망막병증이 생기고 15년이 지나면 거의 90%환자가 망막병증이 생긴다. 이밖에도 고혈압, 임신, 신장질환, 고지혈증과 같은 위험인자들이 있으며 어린이나 사춘기에 당뇨병이 있는 경우에는 조기에 망막병증의 빈도가 매우 높게 나타난다.

당뇨병성 신경병증은 당뇨병성 망막질환, 당뇨병성 신장질환과 더불어 당뇨의 3대 합병증으로 알려져 있다. 당뇨병성 신경병증의 원인은 확실하게 정립되어 있는 것은 없으나 높은 혈당으로 인하여 유발된 신경섬유 부종이 원인이라는 보고가 많다. 당뇨와 관련된 모든 합병증과 마찬가지로 신경병증 역시 상당히 초기부터 진행한다. 대개 유병기간이 10년이 넘어 가게 되면 대부분의 당뇨병환자들이 자각적인 증상을 느끼게 되지만 사실은 발병 전 당내성이 존재하는 시기부터 신경병증은 시작된다.

당뇨발의 발생원인으로 신경병증 및 혈관병증이 있다. 신경병증의 경우 발의 자기 방어기전의 소실로 족부에 궤양이 유발되나, 혈관병증에 의한 혈액순환 장애는 궤양의 발생뿐 아니라, 산소 및 영양공급을 차단 시켜 궤양의 치료까지 어렵게 만들어 발이 까맣게 썩어가는 괴사까지 초래하게 된다.

Nerve conduction studies (NCS) are the most objective measure of nerve function and essential for the diagnosis of sub-clinical neuropathy in diabetes mellitus and diabetic polyneuropathy (DPN). This study evaluates the characteristic of electrophysiological abnormalities in DPN. Electrodiagnostic data from 120 patients with diabetic polyneuropathies and 77 control subjects were reviewed. Motor nerve conduction velocities (MNCV), distal motor latencies (DML), compound muscle action potential (CMAP) amplitudes, No potential frequency and conduction block were analyzed. Data were normalized based on normative reference values, and the proportion of nerves with abnormal values in the lower and upper limbs were evaluated. DPN was systemic demyelinating peripheral polyneuropathy and more severe abnormal nerve conduction was found in lower limbs than in upper limbs. The abnormal degree was more severe in peroneal nerve. It was no statistically significant difference of conduction block in control and DPN group. Our findings suggest that DPN had more common and severe peroneal nerve involvement in the motor nerve conduction studies (MNCS). These findings have important implications for the electrophysiological evaluation of DPN.

Purpose : This study aimed to determine the influence of low-dose oxygen ($FiO_2$ <25%) therapy through nasal cannulae on the progress and prognosis of retinopathy of prematurity (ROP) as well as methods of preventing ROP. Methods : Our subjects comprised premature infants (gestation period <37 weeks; birth weight <1,750 g) born in Daegu Fatima Hospital between February 1, 2001 and January 31, 2006. We retrospectively reviewed and analyzed the medical records of 273 patients who were available for eye examination and follow up over 6 months. Results : The factors maximally influencing the occurrence of ROP were low gestation age and low birth weight. We observed that the incidence of ROP increased with the increasing duration of low-dose oxygen therapy. ROP onset was delayed during ongoing oxygen therapy; however, rapid progression of ROP occurred after the discontinuation of oxygen therapy among premature infants up to the prethreshold stage. Conclusion : To prevent of occurrence of severe ROP and its rapid progression, the period of low-dose oxygen therapy needs to be shortened. Moreover, frequent eye examinations should be performed after the discontinuation of oxygen therapy.

1. Purpose : The correct constitutional diagnosis and the accurate prescription are very important in clinical application of Sasang Constitutional Medicine. Lee Je-ma emphasized that symptom is the best clue to diagnose constitution in "DongYi Suse Bowon". After research the characteristics of each constitution's symptoms and the backgrounds of constitutional prescriptions, this paper is to know the correct clinical application of Sasang Constitutional Medicine. 2. Method : Through the clinical applications of "DongYi Soose Bowon" and "Dongyi Sasang Sinpeun", the characteristics of constitutional symptoms and the application of prescription were researched 3. Results & Conclusions 1) The symptoms of Sasang Constitutional Medicine were came from the Hyung-Sang Medicine(形象醫學) which were important to mind-body equally and from the summarizing spirit of four Qi such as Warm-Hot-Cool-Cold(溫熱凉寒) 2) The symptoms of Soeumin and Soyangin are the Cold-Hot symptoms of ingestive food(水穀) and the treatment of symptoms is to control the ascent-descent of up and down. The symptoms of Taeumin and Taeyangin are the Warm-Cool symptoms of Qi-Yack(氣液) and the treatment of symptom is to control the unfasten-fasten of interior and exterior. 3) The symptoms of Taeyangin are 'Weak Lower part and Firm Upper part symptom'(下虛上實病證) and 'Blood and Yack Exhasted Symptom'(血液俱耗病證), the symptoms of Soeumin are 'Fall Down Symptom'(下陷病證) and Stomach Cold Symptom(胃寒病證), the symptoms of taeumin is 'Dryness Fever Symptom'(燥熱病證) and 'Interior Fever Symptom'(燥熱病證), the symptoms of Soyangin is 'Fire Fever Symptom'(火熱病證) and 'Interior Fever Symptom'(燥熱病證). 4) The characteristics of sasang constitutional symptoms are the exterior-interior symptoms classified with nature-emotion and cool-hot, the inclusive control of exterior-interior symptoms with healthy energy, and the classification of ingestive food symptoms and Qi-Yack symptoms. 5) The characteristics to treat symptoms are the classification of seriousness and obedience, the use herbs according to each constitutions, and inclusive symptoms control.

Purpose: The relationship between retinal conditions such as macular thickness and retinal volume of the eyes with central serous chorioretinopathy(CSC) and visual acuity was investigated. Methods: A total of 136 eyes from 78 subjects was divided into 5 groups: CSC eyes under treatment and its asymptomatic contralateral eyes, fully cured CSC eyes after the diagnosis and its contralateral, and normal eyes. Their uncorrected visual acuity(UCVA), best corrected visual acuity(BCVA), retinal thickness and retinal volume were further examined. Results: All of UCVA, BCVA, retinal thickness and retinal volume of CSC eyes under treatment were significantly different from those of asymptomatic contralateral eyes, fully cured CSC eyes and normal eyes. BCVA of the asymptomatic contralateral eyes was not significantly different from it of normal eyes, however, its retinal thickness and volume were significantly different from those of normal eyes. Increased degree of retinal volume along with the increase of retinal volume was greater in CSC eyes and its asymptomatic contralateral eyes, fully cured CSC eyes and its contralateral eyes than normal eyes. Conclusions: From the present study, it was revealed that the retinal thickness and volume of asymptomatic contralateral eyes of CSC increase as well as CSC eyes, and the change of BCVA due to CSC occurs only when the retinal thickness and volume increase in some extent.

Superficial radial neuropathy is a purely sensory neuropathy, usually caused by nerve entrapment in the distal forearm. We report a case of superficial radial neuropathy caused by the anomalous course of the superficial radial nerve, which was found to be spirally encircling the brachioradialis tendon in the distal forearm. To the best of our knowledge, this is the first report of an anatomical variant of the superficial radial nerve that causes neuropathy.

본 연구는 체내 이식형 Pacemaker를 연구하면서 심장 질환을 Therapy 해 주는 방법에 대해 저전력 및 성능향상에 중점을 두고 연구 및 실험을 하였다. 우선적으로 심장의 심박동을 연산량이 적은 Peak_detection에서 체크하여 전력소모를 줄이고 나오는 각 심실 및 심방의 Interval을 Disease_episode 에서 받는다. 여기서 5가지 심실 및 심방에 관한 질환들 (VF : Ventricular Fibrillation, VT : Ventricular Tachycardia, FVT : Fast Ventricular Tachycardia, FAT_AF : Fast Atrial Tachycardia/Atrial Fibrillation, AT_AF : Atrial Tachycardia AT_AF : Atrial Fibrillation)을 판별한 후 각 병증에 맞는 Therapy 값을 출력하게 하였다. 그 외에 남아있는 병증에 대해서도 Therapy가 저전력 및 성능향상 되도록 설계하였다. 기존에 적용되어 있는 Detection 기법에서는 각각의 병증에 대해서 각 Detection이 있어 VF와 VT 사이에 있는 FVT와 같은 병증을 치료할 때 FVT 같은 경우에는 VF와 VT사이에 있는 질병이기 때문에 FVT_VF 및 FVT_VT와 같이 각각의 Detection을 두어 전력 소모가 있었다. 심장에서는 여러 질병이 한번에 나을 수 없다는 것에 착안하여 (심박동 Interval에 의해 질병이 판단되므로) 다른 병증이지만 같은 진단 기준을 쓰는 Detection을 통합함으로써 하나의 모듈로 구성하여 Gate수를 줄이고 저전력을 구현하였다. 또한 병증을 판별하는 진단 기준 모듈 중 Onset_Criterion 재설계하여 좀더 성능 향상에 중점을 두었다.
