Birth Weight Distribution of Twins According to Gestational Age / 대한산부인과학회잡지

OBJECTIVE: To establish intrauterine growth curve for the birth weight of twins on the basis of gestational age. METHODS: The medical records of twin gestations delivered between 1980 and 2001 were reviewed. 610 Twin pairs (1,220 infants) were comprised our study population. The newborns were grouped according to gestational age and the median, 10th, 50th, and 90th percentile birth weight for each gestational week were calculated. Intrauterine growth curve of twins was compared with that of singletons of Wonju Christian Hospital. We studied the differences of birth weights of twins as sex, parity, chorionicity in twins. RESULTS: The birth weights of twins fall below that of singleton after 32-33 weeks. The 50th percentile for twins falls below the 10th percentile for singleton after 37 weeks, and 90th percentile for twins falls below the 50th percentile for singleton. The mean birth weight in male twin infant was heavier than in female twin infant through all gestational week. The mean brith weight in multiparity was heavier than in nulliparity through all gestational week. The mean birth weight in dichorionic twins was heavier than in monochorionic twins through all gestational week. CONCLUSION: We presented twin specific birthweight curve on the basis of gestational age. The growth pattern of twins was different from that of singleton. We recommend the twin specific birthweight curve in the management of twin gestations.

A Case of Primary Uterine Angiosarcoma / 대한산부인과학회잡지

Angiosarcoma is defined as a malignant tumor of the endothelial cells present in blood vessels and represents less than 1% of all soft tissue sarcomas. Primary uterine angiosarcomas are particularly rare, and tend to have poor prognosis mostly related to the aggressive nature and the metastatic potential of these tumors. They present most commonly with vaginal bleeding or with weight loss and a pelvic mass. Although postoperative radiation and combination chemotherapy are options being utilized, the results have only shown limited success. We report a case of primary uterine angiosarcoma with a brief review of literature.

The Efficacy of Computed Tomography in the Staging of Carcinoma of the Uterine Cervix / 대한산부인과학회잡지

OBJECTIVE: The authors have aimed to compare the efficacy of the computed tomography with other study methods, and to investigate if replacement by computed tomography is possible METHODS: From January 1998 to December 2002, 203 cervical cancer patients underwent pre-staging studies including computed tomography. The positive predictive values, negative predictive values, sensitivity, specificity of each method of study were compared. RESULTS: 1. Compared computed tomography with intravenous pyelonephrography. Each values of computed tomography for hydronephrosis or non visualization of kidney were sensitivity 91.7%, specificity 97.8%, positive predictive values 84.6%, negative predictive values 98.9%. 2. Compared computed tomography with cystoscopy. Each values of computed tomography for bladder invasion were sensitivity 90%, specificity 95.8%, positive predictive values 52.9%, negative predictive values 99.4%. 3. Compared computed tomography with sigmoidoscopy. Each values of computed tomography for rectal invasion were sensitivity 80%, specificity 94.4%, positive predictive values 26.6%, negative predictive values 99.4%. CONCLUSION: Rather than routine examination for staging of invasive cervical cancer in all patients, it is more ideal to first take a non invasive technique. then perform on intravenous pyelonephrography, cystoscopy and sigmoidoscopy only in patient showing positive findings of hydronephrosis or non visualization of kidney, bladder or rectal invasion on computed tomography.
