BACKGROUND: Passive smoking is an important worldwide public health issue. In many Korean studies, parental smoking has been reported to be associated with reduced pulmonary function in children. But few studies have evaluated the effects of passive smoking on pulmonary function in adults. Therefore, we looked into this association in the study. METHODS: Participants in the study included non-smoking, healthy men (n=46) and women (n=326) from rural Korea enrolled from June to December 2006. Exposure to passive smoking was assessed by a self-administered questionnaire, and standardized pulmonary function tests were performed. RESULTS: There were significant reductions in forced expiratory volume in 1 second (FEV1, % of predicted) and forced mean expiratory flow rate 25-75% (%) among the men exposed to passive smoke compared with those not exposed (55.7 vs 75.8, P=0.010; 33.9 vs 58.6, P=0.029, respectively). There were significant reductions in FEV1 among men exposed at both workplace and home compared with men exposed only at either workplace or home (42.8 vs 49.3, 64.6; P=0.034). No significant difference in pulmonary function was found between women exposed to passive smoke compared those not exposed. There were, however, reductions in FEV1 and FEV1/forced vital capacity among the women exposed at workplace. Regression analysis showed that passive smoking negatively affected lung function, which were not statistically significant. CONCLUSIONS: Exposure to environmental tobacco smoke, particularly at the workplace, adversely affects pulmonary function in adults.

OBJECTIVE: The purpose of this study was to evaluate of course of delivery & perinatal outcomes for postterm pregnancy compared with fullterm pregnancy. METHODS: This study included 360 cases of postterm pregnancy out of 16,992 cases delivered at Department of Obstetrics and Gynecology from January 1, 1993 to December 31, 1997. 16,143 cases of full term deliveries of 38 to 42 gestational weeks conducted in same period were used as the control group. Postterm pregnancy was defined as a pregnancy that it exceeds 295 days calculated from first day of the last menstrual period. RESULTS: The incidence of postterm pregnancy was 2.13% with the highest incidence occurring in the 26 ~30 years age group. This study group was significantly different from the control group in the incidence of fetal distress (10.28% vs. 2.20%), large fetus (10.83% vs. 6.95%), perinatal death (1.67% vs. 0.27%). CONCLUSIONS: Adverse perinatal outcomes were increased markedly as the gestational weeks to be prolonged. Therefore, careful prenatal care, accurate determination of delivery date is very important.

Cerebral venous sinus thrombosis (CVST) following a closed head injury in pediatric patients is a rare condition, and an early spontaneous recanalization of this condition is extremely rare. A 10-year-old boy was admitted with a mild, intermittent headache and nausea five days after a bicycle accident. The brain computed tomography showed an epidural hematoma at the right occipital area with pneumocephalus due to a fracture of the occipital skull bone. The brain magnetic resonance imaging and the magnetic resonance venography demonstrated a flow signal loss from the right sigmoid sinus to the right jugular vein. The diagnosis was sigmoid sinus thrombosis, so close observations were selected as a treatment for the patient because of his gradually improving symptoms; however, he complained of vomiting 14 days the after conservative treatment. The patient was readmitted for a further examination of his symptoms. The laboratory and the gastroenterological examinations were normal. Due to concern regarding the worsening of the sigmoid sinus thrombosis, the brain magnetic resonance venography was rechecked and it revealed the recanalization of the venous flow in the sigmoid sinus and in the jugular vein.

The shortage of available organ donors is a significant problem and various efforts have been made to avoid the loss of organ donors. Among these, extracorporeal membrane oxygenation (ECMO) has been introduced to help support and manage potential donors. Many traumatic brain injury patients have healthy organs that might be eligible for donation for transplantation. However, the condition of a donor with a fatal brain injury may rapidly deteriorate prior to brain death determination; this frequently results in the loss of eligible donors. Here, we report the use of venoarterial ECMO to support a potential donor with a fatal brain injury before brain death determination, and thereby preserve donor organs. The patient successfully donated his liver and kidneys after brain death determination.

5.Endovascular Treatment of a Large Partially Thrombosed Basilar Tip Aneurysm.
Journal of Korean Neurosurgical Society 2012;51(1):62-65
Despite the remarkable developments in neurosurgical and neuro-interventional procedures, the optimal treatment for large or giant partially thrombosed aneurysms with a mass effect remains controversial. The authors report a case of a partially thrombosed aneurysm with a mass effect, which was successfully treated by stent-assisted coil embolization. A 41-year-old man presented with headache. Brain computed tomography depicted an 18x18 mm sized thrombosed aneurysm in the interpeducular cistern. More than 80% of the aneurysm volume was filled with thrombus and the canalized portion beyond its neck measured 6.8x5.6 mm by diagnostic cerebral angiography. Stent-assisted endovascular coiling was performed on the canalized sac and the aneurysm was completely obliterated. Furthermore, most of the thrombosed aneurysm disappeared in the interpeduncular cistern was clearly visualized follow-up brain magnetic resonance imaging conducted at 21 months. The authors report a case of selective coiling of a large, partially thrombosed basilar tip aneurysm.

The infantile polycystic kidney disease is rare fetal urinary tract anomaly. It is inherited with an autosomal recessive pattern and recurrence rate is 25%. The gene locus is on chromosome 6p. The pathogenesis of infantile polycystic kidney is the primary defect of the collecting ducts. The ultrasonographic finding of infantile polycystic kidney is oligohydramnios, bilaterally symmetrical enlarged kidneys with maintenance of their reinform shape. The differential diagnosis with adult polycystic kidney disease is important. The massive enlargement of the kidneys is rarely seen in adult polycystic kidney disease and the examination of the parents and other members of the family is helpful to confirm the adult polycystic kidney disease. If there is severe renal involvements, stillbirth or neonatal death secondary to pulmonary hypoplasia would be developed. If it were diagnosed before viability, termination of pregnancy is recommended. In a fetus at risk, diagnosed after viability, pregnancy termination is also recommended since this condition is uniformly fatal. We present a case of infantile polycystic kidney.

10.A study of histomorphological change of curved root canal preparation using GT rotary file, profile and stainless steel K-file.
Journal of Korean Academy of Conservative Dentistry 2002;27(6):612-621
The purpose of this study was to compare the histomorphological change of curved root canal preparation using GT rotary File, Profile .04 taper and stainless steel K-file. 45 mesial canals(over 20 degree) of extracted human mandibular first molars were mounted in resin using a modified Bramante muffle system and divided into three groups. The roots were cross-sectioned at 2.5mm, 5mm and 8mm levels from apical foramen. Tracings of the canals were made from preinstrumentation pictures of the cross section. The canals were prepared using a step-back technique with stainless steel K file(group 1), Profile .04 taper rotary file(group 2) and GT rotary file(group 3). Tracings of the prepared canals were made from postinstrumentation picture. Canal centring ratio, amount of transportation, area of dentin removed and shape of canal were measured and statistically were evaluated with Student-Newman-Keuls test using Sigma Stat(Jandel Scientific Software, USA). The results were as followings: 1. Amount of transportation of group 2 was the lowest at apical part, but there was no statistical difference. The direction of transportation was the outside of curvature at apical part. 2. Centering ratio at the apical part of group 1 was the highest, and there was statistical differences between apical and middle part, apical and coronal part(p<0.05). Centering ratio at the middle part of group 3 was the lowest, and there was statistical difference between apical and middle part(p<0.05). Centring ratio of group 2 was the lowest at apical part, but there was no statistical difference. 3. Amount of dentin removed of group 1 was the highest at coronal, middle and apical part among three groups, and there was statistical difference(p<0.05). 4. The majority of the cross-sectioned canal shape after instrumentation were irregular at coronal, middle and apical part. But there are more number of round shaped canals at group 3 than other group.
