PURPOSE: High flow rate (FR) and pressure limit (PL) strategy with time-cycled pressure-limited (TCPL) ventilator is employed routinely in the neonates. Theoretical basis of this strategy is the two-compartment theory that the lung with acute respiratory failure consists of units with different compliance and resistance. But such constant pressure strategy has the risk of ventilator induced lung injury. We compared the ventilatory indices and clinical outcomes of two different strategies, high FR-constant pressure and low FR-constant FR in the ventilator care of the neonates with acute respiratory failure. METHODS: For the neonates born in our hospital and treated with mechanical ventilation from March to August in 1997, two different ventilator strategies were employed randomly with flow control ventilator. In the high-FR group, the FR was fixed at 10 L/ min and the PL was adjusted according to the arterial blood gas analysis (ABGA) results. In the low-FR group, the FR was adjusted to 10 mL/kg of tidal volume. Sixty neonates were enrolled, 32 in high-FR and 28 in low-FR group. Ventilatory indices and clinical outcomes were statistically cornpared in the two groups. RESULTS: Perinatal factors were not different in the two groups. Initial ventilator settings, ABGA results and ventilatory indices were not different. The tidal volume, fraction of inspired oxygen, peak inspired pressure and oxygenation index were higher and dynamic compliance was lower in the high-FR group compared to the low-FR group after 3 to 72 hours of ventilator care. In clinical outcomes, incidences of pulmonary interstitial emphysema, pneumothorax and chronic lung disease were significantly lower in the low-FR group. CONCLUSION: Low-FR with constant FR strategy resulted in better clinical outcomes in the ventilator care of neonates. We conclude that constant FR strategy prevents damage of the better compliant lung units and decreases the incidence of acute and chronic complications of ventilator care.

The clinical entity of Dysplasia Epiphyseal Multiplex was first descrihed by Fairbank in 1935, characterized by the disturbance of endochondral ossification in hoth epiphyseal centers and regions of physeal growth. It manifests itself radiologically as late appearance and mottling of the ossification centers and clinically as short stature, stubby digits and painful stiffness of multiple joints. It is typically transmitted as an autosomal dominant trait though recessive forms have been described. The spine is normal apart from a mild increased lumbar lordosis. Many patients are referred to an orthopaedic surgeon for bilateral Perthes disease, as was one of the authors cases. This Paper reports four cases of multiple epiphyseal dysplasia which affected one family.

Limited data are available on inappropriate shocks in Korean patients implanted with an implantable cardioverter-defibrillator (ICD). We investigated the impact of inappropriate shocks on clinical outcomes. This retrospective, single-center study included 148 patients treated between October 1999 and June 2011. The primary outcome was a composite event of all-cause mortality or hospitalization for any cardiac reason. The median follow-up duration was 29 months (interquartile range: 8 to 53). One or more inappropriate shocks occurred in 34 (23.0%) patients. A history of atrial fibrillation was the only independent predictor of inappropriate shock (hazard ratio [HR]: 4.16, 95% confidence interval [CI]: 1.89-9.15, P < 0.001). Atrial fibrillation was the most common cause of inappropriate shock (67.7%), followed by supraventricular tachycardia (23.5%), and abnormal sensing (8.8%). A composite event of all-cause mortality or hospitalizations for any cardiac reason during follow-up was not significantly different between patients with or without inappropriate shock (inappropriate shock vs no inappropriate shock: 35.3% vs 35.4%, adjusted HR: 1.06, 95% CI: 0.49-2.29, P = 0.877). Inappropriate shocks do not affect clinical outcomes in patients implanted with an ICD, although the incidence of inappropriate shocks is high.

PURPOSE: The mechanisms underlying syncope remain unknown in about 20% of patients with recurrent syncope. The implantable loop recorder (ILR) has been shown to be a useful diagnostic tool in patients with unexplained syncope even after negative initial evaluations. Nevertheless, ILR has rarely been used in clinical practice. MATERIALS AND METHODS: This study included 18 consecutive patients who had an ILR implanted at our center because of recurrent unexplained syncope after extensive diagnostic tests between February 2006 and June 2011. RESULTS: Diagnosis was confirmed in 10 (55.6%) of the 18 enrolled patients (13 males, 61+/-15 years). The confirmed diagnoses included sick sinus syndrome (n=6, 60%), advanced atrioventricular block (n=2, 20%) and ventricular tachyarrhythmia (n=2, 20%). The mean follow-up durations of the total study subjects and the diagnosed patients were 11.3+/-10.6 months and 5.6+/-9.2 months, respectively. Of the 10 diagnosed patients, 8 (80%) were diagnosed within 6 months of loop recorder implantation. CONCLUSION: ILR may be a valuable and effective diagnostic tool for patients with unexplained syncope.

We experienced a case of clipping of an intracranial aneurysm of a 63 year old male with a subarachnoid hemorrhage under general anesthesia. Preoperative electrocardiography showed complete Left Bundle Block (LBBB) without subjective symptoms. Among the intraventricular blocks, bundle branch block is the most common type and in particular, complete LBBB may progress to the more serious condition of complete heart block. Consideration of anesthetic management in such patients requires a knowledge of normal cardiac physiology, neurophysiology, the circulatory effects of various anesthetic agents and the pathophysiology of these diseases, to prevent any hypertension in response to intubation and surgery. We report upon the anesthetic management of a patient for clipping of an intracranial aneurysm with complete LBBB, which was performed successfully without complication.

OBJECTIVES: This study was performed to investigate the nutritional status, health conditions, eating habits and experience and demand for nutrition.dietary management of senior citizens. And these data are formed foundation of development of nutrition.dietary management education program and contents in welfare facilities for the aged. METHODS: We visited 3 public health centers, 3 senior citizens centers, and 4 welfare centers in Seoul, Gyeonggi-do, Chungnam province, and Daejeon area and carried out interview by semi-structured questionnaire for senior citizens older than 65 years who use those facilities. RESULTS: The study included 17%, 30.7% and 52.3% of senior citizens from public health centers, seniorcitizen centers and and welfare centers, respectively. The age range of 43.9% of the population was 65-74 years and and 56.1% were older than 75 years. We observed that 83.2% of subjects took some medicines due to diseases that they have and 58.0% took prescription medicines for hypertension. The thing that they considered the most when selecting food was 'the taste'(p<0.05). Regarding the level of practice to keep the dietary life, they answered more than 'average' for most of items but answered less than 'average' for lot of salt intake, drinking, exercise. For the experience of nutritionddietary life education, only 19.8% answered 'Yes' and the service for nutritionddietary life management showed the highest score in the demand for 'provide nutritious food'. For the size of consulting group for nutrition/dietary life education, the public health center and welfare center preferred a larger group size but the senior citizens center preferred a smaller group. With regard to who will carry out the consulting, the demand for dietitian was the highest and the operation type showed the high demand in the order of consulting, education. The contents that they want to have consultation in nutritionddietary life education were diet therapy for diseases and the ordinary diet therapy for health. CONCLUSIONS: This study suggested the management of nutritionddietry life necessitates qualitative measures according to the different types of welfare facilities. For these, it is in need of development of counseling and education program included therapy for disease. Above all, the policy to secure dietitian of welfare facilities for the aged to perform these should be achived.
