Patau syndrome, or Trisomy 13 is one of the most common autosomal aberration associtated with multiple congenital abnormalities. We report a case with trisomy 13 mosacism which was found during an amniocentesis performed due to the age of the mother and abnormal nuchal translucency. The clinical features of fetus included cleft lip and palate, low set ears, polydactily, small ""micro"" penis, and Rocker-bottom feet. After termination of the pregnancy, the fetus was sent for an autopsy. The autopsy report was compatible with the gross findings and pulmonary hypoplasia, microophthalmia, hypoplasia of left ventricle of heart were found.

Chronic cough is a symptom frequently encountered by the pediatrician. Although most coughs are self-limited, chronic cough often proves to be a frustrating problem. This study was performed at Kangnam St. Mary's Hospital from January 1, 1992 to December 31, 1992, and 83 children with chronic cough persisting for longer than 3 weeks was evaluated. We categorized these patients into 5 age groups (1. Infant: uner 12 months of age, 2. Toddler: above age 1~below age 3, 3. Preschool: above age 3~below age 6,4. School: above age 6~below age 6~below age 12, 5. Adolecent: above age 12). The most common cause of chronic cough was the reactive airway disease (71.1%) such as asthma with or without sinusitis (56.6%) and bronchiolitis-reactive (14.5%). In infant age group, the most frequent causes of chronic cough were reactive airway disease(52.4%)such as bronchiolitis-reactive (28.6%) and infantile asthma (23.8%). The second and third common causes were congenital anomalies(23.8%) and bronchiolitis-nonreactive (23.8%). In toddler age, the most common cause was the reactive airway disease such as infantile asthma (10 cases: 50%) and bronchiolitis reactive (6cases; 30%) and congenital anomalies were the second common causes of chronic cough. In preschool, school and adolescent age group, asthma and sinusitis were the main causes of chronic cough. In the groups above age 3,73.2% of chronic cough were associated with sinusitis. Therefore, in the diagnostic and therapeutic approach of chronic cough, it should be considered that the cause of cough is either reactive airway disease with or without sinusitis or not. In infant and toddler age, congenital anomaly should be considered.

Three patients(1%) with recurrent molar pregnancy were managed arnong 317 registered molar pregnancies at the department of Obstetrics and Gynecology, Hanyang University Hospital between 197S and 1991. Reeurrent molar pregnancy seemed to be oaiated with a worsening histology and an increased incidence of proliferative trophoblastic sequelae in the successive episodes of hydatidiform mole. The treatment of recurrent mole is discussed and the literature regardmg recurrent rnolar pregnancy is reviewed.

OBJECTIVE: Proopiomelanocortin (POMC) gene is involved in various neuroendocrine reproductive activities and its principal areas of expression are hypothalamus and pituitary gland. However, as it is known as low copy gene, detection of its expression by in situ hybridization is challenging. This study was to examine the degree of basal expression of POMC mRNA and anatomic localization of its expression in rat hypothalamus and pituitary gland as a preliminary study for related reproductive endocrine researches. METHODS: Hypothalamus and pituitary gland of ovariectomized female Spraque-Dawley rat (weight: 250-300 g) was obtained by decapitation with preservation of POMC mRNA by cardiac perfusion of 4% paraformaldehyde. Then, coronal sections of hypothalamus and horizontal sections of pituitary gland were made after paraffin embedding. For in situ hybridization, 35S-labeled antisense RNA probe was used and after in situ hybridization reaction and serial washing procedure, detection of its signal was made by emulsion autoradiography of slide and dark field microscopic examination was done for photographic documentation. Anatomic localization of various nucleus of hypothalamus was done by method proposed by Paxinos and Watson1. RESULTS: Strong expression signal of POMC mRNA was detected in the intermediate lobe of pituitary gland. Less strong, but evenly distributed signals were also detected in the anterior lobe of pituitary gland. In hypothalamic sections, entire area of arcuate nucleus from rostral to caudal direction (between bregma -2.80 mm to bregma -4.30 mm area) showed clear and strong signal of POMC mRNA expression. CONCLUSION: Though POMC gene is known as low copy gene, its basal mRNA expression in pituitary gland and hypothalamus in ovariectomized rat were detectable by in situ hybridization technique. As subpopulation of arcuate nucleus are under complex differential regulation, this in situ hybridization model would be helpful for understanding the effects of various regulatory factors on expression of POMC gene in the specific anatomic area of hypothalamus and pituitary gland.

Doppler sonography has been introduced to evaluate uterine and ovarian diseases. It has been reported to be used to distinguish benign from malignant adnexal masses. The purpose of this study was to assess the blood flow characteristics of adnexal masses and to determine the optimal cut-off points for the Doppler indices obtained, resistance index and pulsatility index, to best differentiate benign from malignant lesions. We performed pulsed Doppler ultrasound in seventy-eight adnexal masses between February 1989 and June 1994. The pulsatility and resistance index were calculated from the waveforms generated from blood flow within the ovary. There were 51 benign and 27 malignant histologically proved ovarian lesions. All women have been operated on. The results were as follows ; Benign tumors and cysts had a significantly higher pulsatility index(mean, 1.23+/-0.74; range, 4.46-3.36) and resistance index(mean, 0.64+/-0.19; range 0.34-1.43) than did malignant tumors(pulsatility index : mean, 0.87+/-0.49; range, 0.31-2.27; resistance index : mean, 0.50+/-17; range, 0.23-0.8). However, some overlap in individual values for benign and malignant lesions was found. In conclusion, our data suggest that high pulsatility and resistance indices may indicate benign adnexal masses ; however, considerable overlap in pulsatility and resistance indices between benign and malignant lesions were noted, and further work will be needed before the validity of these factors is proved.

The retraction of anterior teeth could be performed more easier by inducing of skeletal anchorage system rather than by conventional method on orthodontic treatment. But, we wonder how effective the system draws well without anchorage loss and draws anterior teeth aside posteriorly, and if the system can reduce the time, in comparison with the anchorage of posterior teeth. For that reason we have studied on the subject of patients, who were required the maximum anchorage on orthodontic treatment and the cases without crowding. The subjects of the experimental group are 35 areas of 20 people who were inserted miniscrews after Mx or Mn 1st premolar extracted. Also, the subjects of the control group are 81 areas of 45 people who were not inserted miniscrews. Compared the anchorage loss of experimental group with control one, we could get the result that the anchorage loss of experimental group is 1.034+/-0.891mm and control group is 2.790+/-1.882mm(P<0.01). Compared the space closing time of experimental group with control one, we could get the result that the space closing time of experimental group is 369.40+/-110.81days and control group is 406.56+/-231.63days. But the result of comparing space closing time has no significance in statistics. We recognized that the experimental group is more faster than the control group in the canine retraction velocity from the result ; the speed of a experimental group has as much as 0.60+/-0.23mm/30days while the speed of a control group has 0.44+/-0.35mm/30days(P<0.05). So, we could convince that orthodontic miniscrew is used effectively in the cases required the maximum anchorage.
