We conducted this cohort analytic study to determine whether women with unexplained elevations of maternal serum hCG at 15-18 weeks' gestation are at increased risk for pregnancy complications and adverse perinatal outcomes. The inclusion criteria were a singleton gestation, a confirmed gestational age, and an hCG level greater than 2.0 multiples of the median (MoM). The exclusion criteria were fetal anomalies, an abnormal karyotype, molar pregnancy, and an MSAFP level greater than 2.5 multiples of the median (MoM). A group of randomly selected women with hCG levels under 2.0 MoM served as controls. Patients with elevated levels of hCG had a significantly higher risk for PIH (17.9% versus 4.5%; P <.05) and preterm delivery (17.9% versus 3.5%; P<, 05) than control. But no significant differences were observed in the incidence of intrauterine growth restriction and low birth weight and in the newborn weight. We suggested that pregnancies with unexplained elevated hCG levels should be regarded as high-risk pregnancies. And these patients require careful monitoring with adequate obstetric management.

In order to evaluate the confounding factors of neurobehavioral tests and the neurobehavioral effects in the workers exposed to organic solvents, NCTB was carried out on 100 workers. 46 workers had never been exposed to neurotoxic substances, and the others were being exposed to the solvents, mainly toluene. Simple reaction time, digit symbol, Santa Ana dexterity test and persuit aiming were different with age in non exposure group. Simple reaction time was carried out well in males, and digit symbol and persuit aiming were in females. There was no difference at educational level when the subject was educated over 12 years. Santa Ana dexterity and Benton visual test differed according to exposure level to toluene, however simple reaction time didn't. The acute neurotoxic effect was not excluded in this study. But, NCTB could be used to evaluate and prevent neurobehavioral changes in workers exposed to neurotoxic solvents in Korea.

In unanesthetized rabbits, alcohol, glyserin, or heavy water was injected intravenously and nystagmic reaction elicited by passive alteration of body position was recorded by means of nystagmography, and the specific direction of the nystagmus was also observed. The following results were obtained 1. After Injection of alcohol (2.5~3.5ml/kg), right sloe down or lelf side down position elicited nystagmus in both eyes (FAN I) Right sloe down position elicited supero-dorsal nystagmus in the ipsilateral eye anti Infero-central nystagmus In the contralateral eye Left side down position produced nystagmus towards reversed directions 2. Returning to neutral position from one sloe down also elicited nystagmus towards the same direction. 3 From 5~6 hours after Injection of alcohol, the direction of the positional nystagmus was reversed, manifesting phase II of the PAN (PANII) 4. Injection of glycerin (2.0~3.0ml/kg) or heavy water (2.0~25ml/kg) also elicited positional nystagmus. The direction of the nystagmus was the same as and opposite to that Induced by alcohol Injection

PURPOSE: The purpose of this study was to describe the anglographic finding and clinical result of transarterial embolotherapy(TAE) in patients with injuries of renal artery branches by blunt trauma. MATERIALS AND METHODS: The study was based on retrospective analysis of seven cases, in which TAE was attempted for the control of traumatic renal arterial bleeding. All procedures were performed via the transfemoral approach. TAE was performed with stainless steel coil in two cases, Gelfoam in one case, and Gelfoam and stainless steel coil in four cases. RESULTS: Angiographic findings of vascular injuries were pseudoaneurysm in four cases, extravasation in two cases and arteriocalyceal fistula in one case. All procedures were performed successfully without complication. CONCLUSION: Pseudoaneurysm is a common anglographic finding in patients with injury of renal artery branches and TAE is considered a safe and effective method for treating such cases.

We report a case of an intraparenchymal schwannoma of the left parietal lobe. A 51-year-old woman was admitted to our hospital with complaints of intermittent headaches. Computed tomography and magnetic resonance images revealed a 1.3 cm sized intra-axial homogeneous enhancing mass in the left parietal lobe. The lesion was pathologically confirmed to be a schwannoma.

Background:
The World Health Organization (WHO) proposed a global action plan for dementia and aimed to have 75% of their member states formulating National Dementia Plans (NDPs) by 2025. The Organization for Economic Cooperation and Development (OECD) proposed the ten key objectives of dementia policy in 2015. Among previous studies on NDPs, few studies have investigated measures for proper implementation of NDPs. This study aimed to compare the implementation basis and specific action plans of NDPs between the G7 countries and South Korea.
Methods:
We investigated the measures for proper implementation of the NDPs of G7 countries and South Korea. To compare the specific policy approaches, the seven action areas of the WHO action plan and the ten key objectives of dementia policy proposed by the OECD were integrated into 11 targets (prevention, diagnosis, awareness, caregiver support, appropriate environments, long-term care, health service, end-of-life care, care coordination, research and technology, information systems).
Results:
Although most NDPs included specific action plans of the 11 targets, caregiver support, safe environments, healthcare services, and end-of-life care were lacking in some NDPs. For implementation, some countries reinforced the policy priority of their NDPs by timely updates, evaluation, legislations, or head-of-state leadership. However, only three countries had a legislative basis, and three countries included outcome measures in their latest NDP.
Conclusion
Effective measures for feasible implementation are needed. The WHO should promote not only the establishment of NDPs, but also their proper implementation.

Benign metastasizing leiomyoma usually occurs in women and is associated with a past hysterectomy in 80% of the cases, which is a rare entity. The patient was a 39-year-old woman who complained of cough and sputum. She underwent hysterectomy beacuse of benign leiomyoma ten years age. Chest X-ray showed nodular lesion in the left lung field. Chest CT showed a 3cm sized round well defined mass at left hilum with mild indentation of segmental bronchi of left upper lobe and a small tiny nodule in right lower lung field. Nodular lesion of left upper lobe was resected by thoracotomy.Pathological evaluation showed benign spindle-like cells having nuclei without cytotic atypia similar to those of benign leiomyoma. Immunohistochemical stainings for desmin and smooth muscle actin were positive. Therefore these nodules are considered as benign metastasizing leiomyoma from a uterine leiomyoma. We report this case with the review of literature.

Relapsing polychondritis (RP) is an uncommon disorder of unknown etiology characterized by inflammation and destruction of the cartilaginous structures of many organs, including the tracheobronchial tree. We experienced a rare case of RP diagnosed after stellate ganglion block. A 56-year-old female has been treated under impression of rheumatoid arthritis and bronchial asthma for several years, but her symptoms were not markedly relieved. We performed right stellate ganglion block with 8 mL of 1% mepivacaine for the relief of the right shoulder pain. About 5 minutes later, she complained severe dyspnea and became cyanotic. Bronchoscopic finding was diffuse bronchoconstriction during expiration. We confirmed the diagnosis of relapsing polychondritis by bronchoscopic biopsy finding. Unfortunately, she died 3 months later due to recurrent pneumonia and acute respiratory distress syndrome.

Placement of endotracheal tube, even for extremely short periods, can result in injury to laryngeal and tracheal tissue. This may be clinically insignificant, but in rare cases, it could be life threatening and results in permanent disability. Especially, tracheoesophageal fistula (TEF) is a serious and challenging problem because it may contaminate the tracheobronchial tree and interfere with nutrition. This uncommon but lethal complication has been reported to be associated with certain risk factors in tracheally intubated patients, and better knowledge of these factors could reduce the incidence of post-intubation TEF. We report a case of 49-year old male patient who has acquired TEF caused by endotracheal intubation and positive pressure ventilation.
