OBJECTIVEs: Cytogenetic investigations were carried out on 770 women with primary (n=560) and secondary amenorrhea (n=210) to determine the frequency of chromosomal or genetic causes of amenorrhea. MATERIALS AND METHODS: In 770 women with primary amenorrhea (n=560) and secondary amenorrhea (n=210), chromosomal analysis were performed. RESULTS: 1) The most prevalent age group is 16-20 years of age group with primary amenorrhea and 26-30 years of age group with secondary amenorrhea. 2) Out of 560 cases of primary amenorrhea, 343 cases (61.3%) had the normal chromosome constitution and 217 cases (38.7%) had the abnormal chromosome constitution including 46,XY. 3) In 217 cases of abnormal chromosome of primary amenorrhea, 57 cases (26.3%) had 45,X and 34 cases (15.8%) had the 46,XY, 24 cases (11.0%) had 45,X/46,X,i (Xq), 23 cases (10.6%) had 45,X/46,X,+mar and 14 cases (6.6%) had 45,X/46,XY. 4) Out of 210 cases of secondary amenorrhea, 181 cases (86.2%) had the normal chromosome constitution and 29 cases (13.8%) had 45,X/46,XX. CONCLUSION: High percentage of chromosomal abnormalities was diagnosed in primary amenorrhea and most of them were sex chromosome anomalies. In secondary amenorrhea, the prevalence was lower than primary amenorrhea, so a preselection of patients with secondary amenorrhea for cytogenetic investigations seems to be necessary.

Meningioma of unusual age of onset, location, histogenesis and histologic type is reported. The patient, 4 year-old girl, had an intradural spinal meningioma arising from lumbar nerve root with no dural attachement. The meningioma revealed glycogen-rich, clear cell type with extensive and blocky hyalinization of the stroma. The tumor shared common fibrous sheath with attached lumbar nerve, and nerve fibers were scattered within the tumor. Ultrastructurally, the tumor cells had abundant glycogen particles, intermediate filaments and intercellular desmosomes. Hyalinized material revealed large amianthoid collagen fibers.

PURPOSE: This study was done to identify the influence of workplace violence on anger and post traumatic stress disorder among nurses. METHODS: The research design for this study was a descriptive survey design using a random sampling. Data collection was done using self-questionnaire with 477 nurses. The collected data were analyzed by descriptive statistics, chi2-test and logistics regression. RESULTS: The incidences of total violence, verbal, physical, and sexual violence were 31.2%, 28.7%, 6.3%, 3.6% of the nurses, respectively. Anger was significantly associated with verbal violence (OR: 2.34, CI: 1.40~3.91) and physical violence (OR:4.85 CI: 1.67~14.13). Post traumatic stress disorder was significantly associated with verbal violence (OR: 15.99, CI: 9.58~26.69) and physical violence (OR: 5.37, CI: 1.66~17.40). CONCLUSION: To promote psychological health in nurses, there is a need to develop prevention programs to decrease workplace violence and to develop programs supporting psychological aspects of verbal violence that nurses experience.

OBJECTIVE: The purpose of this investigation is to determine the frequency of chromosomal or genetic causes of recurrent spontaneous abortion. METHODS : A cytogenetic study was made in of 921 couples for 13 years from January 1984 to December 1997 in which the woman was ascertained to have had two or more spontaneous abortions at our Cytogenetic Laboratory, Institute of Reproductive Medicine and Population, Seoul National University. RESULTS : The overall incidence of chromosome anomaly was 80 out of 921 (8.7%). There were 34 cases (3.69%) of reciprocal balanced translocation and 13 cases (1.41%) of Robertsonian translocation. Also 17 cases (1.85%) of inversion and 5 cases (0.54%) of X chromosome mosiacism was observed. In the case of reciprocal balanced translocation, chromosome 8,6,7,13 were preferentially involved over others. And in the case of Robertsonian translocation, chromosome 13 was preferentially involved. CONCLUSION: Our study demonstrates that cytogenetic analysis is indicated in couples with 2 or more spontaneous abortion and about half of these disorders are reciprocal balanced or Robertsonian translocations.

A nationwide survey was conducted to investigate the annual occurrence rate of neonatal sepsis, maternal risk factor in neonatal sepsis, localized infection in neonate, causative organism in nosocomial infection and the most common causative organism in neonatal sepsis in Korea. Clinical and bacteriological data were collected from thirty seven neonatal units through retrospective review of the medical records of the newborn infants who were confirmed as neonatal sepsis by isolating organisms from blood culture during one year study period from January to December in 1997. 78,463 neonates were born at 37 hospital in 1997 and 20,869 neonates were admitted to the neonatal units. During this period, 772 episodes of neonatal sepsis were recorded in 517 neonates. The occurrence rate of neonatal sepsis was 0.73%(0~2.95%). Male to female ratio was 1.15:1 and 303 cases(42.1%) were born prematurely. The main pathogens of early onset sepsis were S. aureus(20%), S. epidermidis(14.4%) and coagulase negative Staphylococcus( 14.4%). Gram negative bacilli including Enterobacter spp (7.2%), E.coli(5.1%), Klepsiella(4.5%), Pseudomonas(3.7%) Enterobacter faecium(3.6%) constitute 24.1%. Only two cases of group B beta-hemolytic Streptococcus were isolated. Common obstetric factors were PROM(21.1%), difficulty delivery(18.7%), fetal tachycardia(5.3%), chorioamnionitis(4.9%), maternal fever(4.7%). The main pathogens of late-onset sepsis were S. aureus(22.3%), S. epidermidis(20.4%) and CONS(9.9%). There were 6 cases (1.0%) of Candida sepsis. Frequent focal infections accompanying sepsis were pneumonia(26.1%), urinary tract infection(10.5%), meningitis(8.2%), and arthritis(3.6%). S. epidermidis(22.0%) and S. aureus(21.7%) were also the most common pathogens in 373 nosocomial infection.

OBJECTIVE: The purpose of this study is to evaluate the clinicopathologic characteristics of the torsion of the ovarian tumor in postmenopausal women. METHODS: We reviewed the medical records of 20 postmenopausal patients with a postoperative diagnosis of torsion of the ovarian tumor in Department of Obstetrics and Gynecology, Hanyang University Hospital from January 1989 to December 1998. RESULTS: The postmenopausal patients with torsion of the ovarian tumor constitute 20/94 (21.3%) of all adnexal torsion patients encountered during this period. The mean (+/-SD) age of the 20 patients was 63.5+/-9.0 years, with a range of 52-90 years. The mean time since menopause was 16.5+/-10.3 years, with a range of 1-39 years. The mean parity was 5.4+/-2.0 (range of 3-10). Lower abdominal pain (65%) was the most frequently presenting symptom, palpable mass(20%) or diagnosed mass(15%) being the second. But, in 20% of cases there was no lower abdominal pain. The torsion occurred at the right side in 11cases (55%) and at the left side in 9 cases. The most frequent degree of torsion was those cases that was rotated twice (720 degrees). The neoplasms undergoing torsion ranged in diameter between 5cm and 30cm and the most prevalent size was 6 to 10 cm (8 cases). Most of the patients (17cases) were treated by total abdominal hysterectomy and bilateral salpingo-oophorectomy. The tumors that produce torsion varied histologically and the most common type was cystic teratoma (in 5 cases), simple cyst(in 3 cases), serous cystadenoma(in 2 cases), mucinous cystadenoma(in 2 cases). CONCLUSIONS: In our study, ovarian tumor torsion occurring in postmenopausal patients constituted approximately 20% of all torsion patients, therefore adnexal torsion should be considered when a postmenopausal woman presents with lower abdominal pain. When torsion is diagnosed, total abdominal hysterectomy and bilateral salpingo-oophorectomy is the usual treatment for postmenopausal patients. Histologically, in more than 90% of cases, the tumors that produce torsion were benign. If cancer is evident, more extensive surgery is required.
