Korean Journal of Preventive Medicine 1981;14(1):13-22
A study was conducted to provide comprehensive information in epidemiological state of crippled schoolchildren in Chungnam area from November 23, 1979 to 19, 1980. In this study, two step survey was conducted upon whole primary, middle and high school, and subsequent selected 537 case in total 3,063 crippled children. The results obtained are as follows; 1. The prevalence rate of orthopedic defect children was 3.7 per 1,000 and dominant male as 6 : 4. 2. It was relatively high the school grade and prevalence rate more increased. Prevalence rate was highest in high school as 4.7 per 1,000, middle in middle school as 4.4 per 1,000 and lowest in primary school as 3.1 per 1,000. 3. The most predominant group was 15-19 age as 52.9 percent. 4. The most common job of their parent was agriculture as 52.9 percent and next job sales and service. Economic state of Cripple's parent have revealed no particular difference. 5. In a family, the most common incidence rate was first children in both sex and decreased by ordered sibling. 6. Poliomyelitis was the most common cause as 71.5 percent and next cerebral palsy 11.9 percent. 7. The most common affected sited was lower extremity (Right: 42.3%, Left: 35.5%) and next upper extremity. Right was more dominant as 55:45. 8. Intelligence was decreased in cerebral palsy predominantly than other cause of defect, including poliomyelitis. 9. For the treatment of their condition at onset of illness, crippled children was utilized private clinic and herb medicine, but was changed tendency of treatment as acupuncture and moxibustion after diagnosis of cause defect.

OBJECTIVE: Attention deficit hyperactivity disorder (ADHD) is common disorder of the school-age population. ADHD is familial and genetic studies estimate heritability at 80–90%. The aim of the present study was to investigate the association between the genetic type and alleles for RELNgene (rs736707, rs2229864, rs362746, rs362726, rs362691, rs1062831, rs607755, and rs2072403) in Korean children with ADHD. METHODS: The sample consisted of 180 ADHD children and 159 control children. We diagnosed ADHD according to DSM-IV. ADHD symptoms were evaluated with Conners' Parent Rating Scales and Dupaul Parent ADHD Rating Scales. Blood samples were taken from the 339 subjects, DNA was extracted from blood lymphocytes, and PCR was performed for RELN Polymorphism. Alleles and genotype frequencies were compared using the chi-square test. We compared the allele and genotype frequencies of RELN gene polymorphism in the ADHD and control groups. RESULTS: This study showed that there was a significant correlation among the frequencies of the rs736707 (OR=1.40, 95% CI=1.03–1.90, p=0.031) of alleles of RELN, but the final conclusions are not definite. CONCLUSION: Follow up studies with larger patient or pure subgroups are expected. These results suggested that RELN might be related to ADHD symptoms.

PURPOSE: Metastatic prostatic adenocarcinoma can be controlled by androgen ablation through the active process of programmed cell death in androgen responsive cells. However, about 20-30% of patients have no clinical response to androgen withdrawal. Because of the importance of apoptosis in effecting tumor control, factors involved in this process may be helpful in predicting androgen insensitivity. So, we evaluated the significance of bcl-2 protooncogene expression pattern with therapeutic response of prostatic cancer MATERIALS AND METHODS: We examined the cellular expression of bel-2 protein using immunohistochemical stain in tumor samples from 40 patients with metastatic prostatic cancer(stage D) and determined whether expression of blc-2 protein has related to the therapeutic response of prostatic cancer. RESULTS: The hormonal status of the patient's tumor was determined by the clinical response to therapy. Androgen independent cancer was defined as that subset of patients who experienced no initial response to androgen ablation, or who experienced disease relapse following an initial response to androgen ablation. So, we found that androgen dependent prostatic cancer was 22 patients and androgen independent prostatic cancer was 18 patients. The positive staining for bcl-2 was 27.3%(6/22) and 83.3%(15/18) in androgen dependent and independent prostatic cancer, respectively. It was significant difference(p<0.05). CONCLUSIONS: These results suggest that bcl-2 expression is associated with androgen independent prostatic cancer and used one of the factors to predict which patient with prostatic cancer will respond to androgen ablation.

PURPOSE: Intravitreal injection of bevacizumab (Avastin(R)) can lead to several intraocular complications including endophthalmitis, hemorrhage and inflammation. We present one case of acute anterior uveitis with hypopyon in an HLA-B27(+) patient following intravitreal injection of bevacizumab. CASE SUMMARY: A 40-year-old male with known central retinal vein occlusion presented with redness and decreased visual acuity in the left eye. Symptoms had developed 4 days earlier after the sixth intravitreal injection of bevacizumab in that eye. The patient had a marked anterior chamber reaction with hypopyon and posterior synechiae. Nine days after onset, similar symptoms in the left eye occurred in the uninjected right eye. Through examination and clinical manifestations, we diagnosed acute anterior uveitis associated with HLA-B27 positivity. The patient was treated with 1% prednisolone acetate, 0.5% moxifloxacin and 1% atropine in both eyes and all symptoms had resolved after 6 weeks.

BACKGROUND: A stenosis of left main coronary artery has critical prognostic importance. Recent reports on successful left main stenting are now challenging traditional treatment patterns for this lesion. We evaluated recent four-year trends in incidence, clinical, angiographic findings and treatment modalities in patients with left main coronary artery stenosis(LMS). METHODS: Patients who were diagnosed as a significant LMS at Yonsei cardiovascular hospital between 1996 and 1999 were analyzed retrospectively. RESULTS: The incidence of LMS during the period of 1996 to 1999 was 3.3%(n=24) and it was significantly higher than that of previous 15 years before 1996(p<0.01). The incidence of isolated ostial lesion was 0.28% and this lesion was more prevalent in young female patients with less risk factors compared with other types of LMS(p<0.01). After exclusion of the patients with an isolated ostial lesion, patients were grouped according to the lesion site: ostium, shaft, and shaft lesion extended to distal vessels. There were no differences in clinical and hemodynamic findings among these groups. Coronary artery bypass graft was performed in 141 patients(63%) and stent implantation in 16 patients(14%). CONCLUSION: The incidence of LMS has been increased. There was no difference in clinical and hemodynamic findings according to the types of LMS. Surgery is still a standard treatment, but in selected patients percutaneous coronary intervention can be another treatment option.

Ovaries lie near the distal ureter where extracorporeal shock wave lithotripsy (ESWL) of calculi is performed. The question whether ESWL may induce morphological changes in ovary should be investigated in animal experiments. After applying shock waves to ovary of Sprague Dawley female rat, the histopathologic changes within the tissue of ovary were observed immediately after shock waves and after recovery. For animal subjects, 25 healthy rats weighing about 250 grams each were used. Five rats were designated as control, and remaining 20 received shock waves at 20 kV for 1,000 times using Pendulum-ESWL (Lithoring), a third generation lithotriptor. The 20 rats were divided into 4 groups before shock waves, and each group was sacrificed after 1, 7, 14, and 28 days, respectively, in order to compare the observed histopathologic changes. Edema, congestion and hemorrhage were observed in ovary after 1 and 7 days of shock waves, but the edema and congestion were significantly reduced on the 14th day and completely disappeared on the 28th day. There was no ovarian follicular changes or fibrosis on the whole. It is thought that the extracorporeal shock waves have no specific effects on the tissues of ovary, but further studies ate needed to determine its long term effects.

This study was performed to investigate the effect of octreotide on the contractility of rat vas deferens. The -smooth muscle strips isolated from the prostatic portion were myographied in isolated organ bath. Electric -field stimulation (monophasic square wave, duration : 1. mSec, voltage : 50 V, frequency : 5 Hz or 30 Hz, train : 10 Sec) produced reproducible contraction. The contraction was composed of two component, first phasic component (FPC) and second tonicc component (STC).. These contractions were abolished by -tetrodotoxin (1 microM). Octreotide inhibited the field stimulation induced contractions both FPC and STC concentration- dependently. The FPC was decreased by a desentization of purinergic receptor by pretreatment of mATP, and the STC was decreased by pr,,creatment of reserpine (3 mg/kg, EP) 24 hours before experiments. Octreotide reduced the field stimulation induced contraction in the presence of mATP and of reserpinized muscle strips. The inhibitory effect of octreotide was more potent at 5 Hz than at 30 Hz. Octreotide did not affect basal ton and exogenous norepinephrine- or ATP-induced contraction. These results suggest that octreotide inhibit the contractility of the isolated rat vas deferens by inhibition of the release of neurotransmitters, both ATP and norepinephrine from adrenergic nerve terminal.

9.Clinical Implications of Serum Biomarkers in Diabetic Cardiovascular Complications.
Korean Diabetes Journal 2009;33(5):363-372
Diabetes is associated with increased risk of cardiovascular disease, with atherosclerosis responsible for most associated morbidity and mortality. Atherosclerosis often causes acute thrombotic events through plaque rupture and formation of platelet-rich thrombi. The principal clinical manifestations of atherosclerosis are coronary artery disease, ischemic stroke, and peripheral arterial disease. Endothelial dysfunction, oxidative stress, and low-grade inflammation are key features in the pathophysiology of atherosclerosis.

BACKGROUND: Efficacy of percutaneous transluminal angioplasty(PTA) in the treatment of Peripheral arterial disease has been established. Complications such ans PTA-induced dissections or residual stenosis with occasional mural thrombi have been reported, which compromise the results. New procedures can be used in combination with PTA to improve the immediate and long term results, such ans prolonged balloon inflation, atherectomy, or implantation of endovascular prosthesis. In addition, the occurrence of other lesions, such as spontaneous or post-catheterization dissection or post-PTA restenosis, has prompted the insertion of a vascular stent. But there was few reports on stenting for peripheral arterial disease in Korea. METHODS: To evaluate the safety, efficacy and stability of stent in peripheral arterial disease, twenty-six consecutive symptomatic patients with 37 peripheral lesions were treated with 39 balloon expandable(33 Strecker and 6 Palmaz)stents with or without prior balloon angioplasty in the period of March 1991 and February 1994. RESULTS: The major cause of disease was arteriosclerosis(22 out of 26). The implantation sites for our study include 22 in common iliac artery, 11 in external iliac artery 2 in aorta, subclavian artery, superficial femoral artery each other. Indication for stent deployment were primarily suboptimal results(19 lesions), insufficient PTA such as dissections(4), restenosis after previous PTA(2), and primary stenting was performed without preceding therapeutic PTA(10). Stent deployment was technically successful in 24 of the 26 patients(92%) and clinical success rate was in 25 of the 26 patients treated(96%). Hemodynamic change revealed markedly improvement before and after stenting(peak pressure difference from 66.329.0mmHg to 9.1+/-7.1mmHg; Mean pressure difference from 33.0+/-22.5mmHg to 4.7+/-4.3mmHg). There were two procedural complications which included one stent migration and one artery perforation. During the 7 months of follow-up(1-18 momths), two restenosis occurred. One patient died due to cerebral hemorrhage during thrombolysis with urokinase. CONCLUSION: The stent deployment is relatively safe and very effective primary therapeutic modality and may abolish the limitation of PTA such as suboptimal result, dissection with sudden occlusion and restenosis in peripheral vascular disease and highly recommended in selected cases.
