Rett syndrome is a newly characterized developmental disorder that affect girls exclusively. These girls are born clinically normal, but their psychomotor development stagnates and deteriorates between the age of 6 months and 2 1/2 years. The full syndrome comprises; aquired microcephaly, severe dementia, autism, loss of purposeful use of the hands, characteristic hand-wringing stereotypies, jerky ataxia of the trunk, epilepsy with various types of fits, and in later years spastic and trophic changes of the lower limbs. There is no known cytogenetic, biochemical or molecular marker for the disorder; the diagnosis is based on clinical criteria. We report a case of Rett syndrome with a brief review of related literatues.

BACKGROUND: The regional fat distribution is known to be related with some cardiovasular risk factors independently to total body fat amount. Regional fat distribution pattern can be assessed by waist to-hip ratio(WHR). WHR distribution patterns depend on age, sex, race and show regional difference. But, our own unique data are inadequate, so we tried to investigate distribution patterns, cut off points and related factors of WHR in middle aged men and women among Korean. METHODS: The study population were middle aged men and women above 40 years old who visited our hospital for routine check up from April to July, 1996. We measured height, weight, blood pressure, waist circumference, hip circumference, fasting blood sugar and total cholesterol in 1,000 persons. We gathered data about diet habits, exercise, smoking and drinking status by standard questionnaire. We analized above data by using SAS for Window 6.10. RESULTS: The study population numbers of men and women were 494 and 499, and average ages of men and women were 49.3 and 50.5 years respectively. For men, the average WHRs as a whole were 0.895, and 0.893, 0.893 and 0.911 in their forties, fifties and above sixties respectively. For women, the average WHRs as a whole were 0.827, and 0.816, 0.837 and 0.850 in their forties, fifties and above sixties respectively. The percentage above WHR 1.0, 0.95, and 0.90 in men were 2.4%, 11.7% and 46% and the percentage above WHR 0.90, 0.85, and 0.80 in women were 8.2%, 32.9% and 68.7%. Adjusting by age, body mass index, WHR was significantly correlated with weight, systolic blood pressure, diastolic blood pressure in men only. For men, WHR was associated with alcohol drinking positively and with exercise negatively. For women, WHR was associated with alcohol drinking and smoking status positively. CONCLUSIONS: The WHR had a tendency to increase according to age. The 90th percentile points in men and women were 0.957 and 0.894 respectively. WHR was related with several cardiovascular risk factors and several life styles.

Pulmonary vein velocities have recently been estimated in conjunction with mitral flow velocities to increase our understanding o ventricular filling. The advent of transesophageal echocardiography with pulsed Doppler imaging capability has provided a method by which both the mitral valve and pulmonary vein velocities can be easily recorded because of the posterior approach providing unimpeded interrogation of cardiac structures. The purpose of this present study was to evaluate the normal pulmonary venous, mitral and aortic flow pattern by transthoracic echocardiography in neonate according to the postnatal age. The results were as follows. 1) With regard to the aortic flow, the early systolic was of pulmonary flow peaked after the onset of aortic flow and the late systolic wave occured consistently before aortic valve closure. 2) The peak velocities of early systolic, late systolic, late systolic, diastolic and atrial systolic in the pulmonary venous flow were 36.4 (13.2cm/sec, 45.3 (15.3cm/sec, 48.5 (14.1cm/sec and 16.6( 5.7cm/sec at 1 day old. the difference according to the postnatal age was not significant. 3) The ratio of peak systolic to peak distolic velocity of pulmonary venous flow was 1.0( 0.3 at 1 day o1, 1.1( 0.4 at 1 week old and 1.2 (0.3 at 1 month old. The difference between old and 1 month old was statistically significant(p<0.05). 4) The peak early diastolic velocity of mitral flow was 51.3 (15.2cm/sec at 1 day old, 54.7( 13.7cm/sec at 1 week old and 80.7 (16.6cm/sec at 1 month old. The difference between 1 week old and 1month old was statistically significant(p<0.01). 5) The peak late diastolic velocity of mitral flow was 48.3 (14.6cm/sec at 1 day old, 50.1( 9.9cm/sec at 1 week old and 71.8 (16.6cm/sec at 1 month old. The difference between 1 week old and 1 month old was statistically significant(p<0.01). 6) The ratio of peak mitral early diastolic to peak late diastolic velocity was 1.1( 0.2 at 1 day old, 1.1( 0.3 at 1 week old and 1.2( 0.7at 1 month old. The difference between 1 week old and 1 month old was statistically significant(p<0.01). 7) The peak aortic valve flow velocity was 62.1 (14.2cm/sec at 1 day old, 67.8 13.4cm/sec at 1 week old and 76.6 14.1cm/sec at 1 month old. The difference between old and 1 month old was statistically significant(p<0.05). In conclusion, improvement of left ventricular diastolic function was noted at 1 month old by echocardiography. These normal data will be useful in comprisons with the data, which obtained in newborn with various congenital heart disease that affects flow dynamics.

PURPOSE: This study was done to investigate the effects of university hospital nurses' organizational conflict between organizational commitment and labor union commitment, so as to provide data on prevention of conflict with the hospital and to improve work achievement with commitment of two different groups: hospital and labor union commitment. METHODS: Data collection was conducted from May 15 to 31, 2011 for nurses registered in the labor union of a university hospital. The collected data were analyzed using t-test, ANOVA, Scheffe test and multiple regression. RESULTS: Organizational commitment of the nurses showed significant differences according to age, position and work experience, and degree of labor union commitment according to academic achievement. The factors affecting labor union commitment were organizational conflict and recognition of need for labor union, which accounted for 19% of the variance. Factors affecting organizational commitment were organizational conflict, recognition of need for labor union, participation in organizational events, and renewal of membership in the union, which accounted for 33% of the variance. CONCLUSION: The results of this study indicate that there is a need to improve work achievement by minimizing conflict and preventing labor disputes for better organizational commitment and labor union commitment of nurses.

Twenty-five neonates were observed for the relationship between phenobrbital loading dose, plasma concentrations and control of seizures. Nineteen neonates (76%) had seizures controlled by phenobarbital alone. Effective plasma concentration were 10.0~31.1microgram/ml. Although 14 neonates had seizures controlled by phenobarbital concentration below 20microgram/ml, neonate required level above 30microgram/ml. We found that continued benefit was obtained until phenobarbital plasma concentrations reached 40microgram/ml and there was no adverse effects on cardiorespiratory function. We recommend that plasma phenobarbital concentrations should equal or surpass 40microgram/ml before additional anticonvulsants are used for neonates with seizure.

We studied the incidence and morphological variation of the metopic suture in Korean. Ninety-six adult Korean dried skulls and 141 cases of antero-posterior skull roentgenograms from age of 1 month to 80years old. We divided metopic suture into complete and incomplete type. Incidence of complete type was 8.3% in dried skulls. In roentgenograms the incidence was decreased according to aging, especially around 6-8 years old, and over 20 years old age group the incidence was 4.0%. The incidence of incomplete type was 32.3%.
