OBJECTIVE: The purpose of this study was to investigate the relationship between menarche and cervical vertebral maturation. METHODS: Lateral cephalograms of 67 young korean girls within the range of 1 year before or after their menarche were gathered. The concavity of the cervical vertebrae base and the ratio of the base length to the 3rd and 4th cervical vertebrae anterior height were measured and analyzed. RESULTS: The mean measured values were as follows; concavity of the 3rd cervical vertebrae base: 1.27 (+/- 0.18) mm, concavity of the 4th cervical vertebrae base: 1.06 (+/- 0.15) mm, ratio of the base length to the 3rd cervical vertebrae anterior height: 0.73 (+/- 0.06) and ratio of the base length to the 4th cervical vertebrae anterior height: 0.70 (+/- 0.05). There was a significant increase in the ratio of the base length to the 3rd vertebrae anterior height and the base concavity of the 3rd and 4th cervical vertebrae during the period of 1 year before to 1 year after their menarche. CONCLUSIONS: These characteristics of the 3rd and 4th cervical vertebrae on the lateral cephalogram can provide useful clues on evaluating the growth stage.

OBJECTIVE: This study aimed to evaluate the mean age of menarche, its secular trend in Korean women, and the relationship between malocclusion and the rate of skeletal maturation, as defined by menarcheal age. METHODS: We retrospectively collected data on menarcheal age from 931 Korean women born during 1961 - 1997. Subjects were divided by the malocclusion type and birth-year decade into 3 and 4 groups, respectively. The mean menarcheal age for each group was determined, and one-way ANOVA was performed for intergroup comparison (p = 0.05). Two-way ANOVA was also performed to compare all the 12 subgroups (p = 0.05). RESULTS: The mean age of menarche was 12.82 years for Korean women born during 1961 - 1997. A distinct downward secular trend of menarcheal age was noticed (p < 0.05). For the birth-year decade 1961 - 1970, the Class III malocclusion group showed earlier onset of menarche than the other malocclusion groups (p < 0.05), but the other birth-year groups did not show any significant difference in the type of malocclusion (p > 0.05). CONCLUSIONS: A positive secular trend towards earlier menarche exists among Korean women. Malocclusion does not show any significant relationship with the rate of skeletal maturation, as defined by menarcheal age.

Uterine leiomyoma is the most common type of benign tumor in women of reproductive age. This disease is rare before menarche, and its incidence decreases after menopause. Uterine leiomyoma is known to be related to hormonal changes, but the precise underlying mechanism has yet to be determined. Although it is a benign disease, the most common form of management involves surgical intervention. Uterine leiomyoma is also related to infertility and obstetric complications. Here, we present a review of the literature regarding uterine leiomyoma and discuss management of this disease.

OBJECTIVE: This study analyzed the morphologic changes of the fourth cervical vertebra body to determine the skeletal age of orthodntic patients during growth. METHODS: Eighty-one female patients aged from 11 to 14 who had cephalograms taken on the same day were examined. The subjects were divided into three groups depending on the depth of the concavity of the lower border of the fourth cervical vertebra (Group A: less than 1.05 mm, Group B: 1.05 - 2.07 mm, Group C: greater than 2.07 mm). Menarcheal timing, SMI stage, length, width and ratio of length and width of the fourth cervical vertebra body were analyzed and the following results were obtained. RESULTS: The average SMI stage of group A,B and C were 5.67 +/- 2.57, 8.73 +/- 2.41, and 10.00 +/- 1.47, respectively. Length, width, ratio of length and width, and SMI stage were greater in group B than group A and in group C than group B. Mean menarcheal timing was 11.64 +/- 0.92 years. Concavity depth, length, width, ratio of length and width showed a significant positive correlation with SMI stage, especially with the concavity depth. CONCLUSION: The results of this study propose a simple method for determining the timing of orthopedic treatment by measuring the concavity depth of the fourth cervical vertebra on the cephalogram.

PURPOSE: This study was undertaken to investigate the relationship between the Risser sign and chronological age and menarche in elementary, middle, and high school students, and to investigate the reliability of the Risser sign. MATERIALS AND METHODS: We reviewed 1, 870 spine standing AP X-rays, which included the iliac crest. We tried to identify a correlationbetween the Risser stage and chronological age, and between Risser stage and menarche. In addition, we investigated inter-observer error in the determination of Risser stage. RESULTS AND CONCLUSION: The mean ages of Risser 1, 2, 3 and 4 female students were 12.9, 13.3, 13.6, and 14.3 years, and the mean ages of Risser 1, 2, 3 and 4 male students were 14.0, 14.3, 14.5, and 15.6 years (Spearman's rho=0.560, p<0.01). The mean menarchal age of female students were 12 years 4 months, which is 7 months earlier than the mean chronological age of Risser 1 in female students. Wefound that it takes 24 months to progress from menarche to iliac crest maturation (Risser 4) (Spearman's rho=0.571, p<0.01). The percentage of agreement in the determination of Risser stage by three orthopaedic surgeons was 73.3%, showing good reliability with a Kappa value of 0.739-0.783.

Among many maturation indicators of growing patients, menarche and skeletal maturity are useful to assess growth and development, and the changes of the first and third finger are relatively important in hand-wrist X-rays. The objective of this study was to evaluate the relationship between menarche and the changes of the phalanx of the first and third finger and compare skeletal maturation among different malocclusion types. The sample used in this study was 29 Class I, 27 Class II and 27 Class III females whose hand-wrist X-rays had been taken with 6 month interval before the appearance of ulnar sesamoid ossification till the phalanges of the fingers were almost fused. The results were as follows. 1. There was no skeletal maturity difference among malocclusion types. 2. There was no difference in the mean chronologic age of menarche among different malocclusion types and that was 12.30+/-0.98 years. 3. The ulnar sesamoid was observed at 10.35+/-1.01 years, and on distal phalanx of the first finger, epiphyseal capping appeared at 11.26+/-1.04 years and fusion at 13.12+/-1.06 years. The epiphyseal capping on middle phalanx of the third finger was observed at 11.57+/-1.02 years and fusion at 13.72+/-1.04 years. 4. The timing of menarche occurred around the same time as the fusion process of distal phalanx of the first finger(p<0.001, r=0.82) and the initiation of fusion of middle phalanx of the third finger(p<0.001, r=0.78). Therefore, we can give the aid when we evaluate the growth and development of growing females seeing the changes at phalanx of the first and finger.

The 123 left hand-wrist radiographs and menarcheal ages attained by direct questioning to patients or her mothers are used, in order to exploit the relationship between the bone maturity and the menarcheal age of girls in adolescence. The results were as follows: 1. The mean age at menarche was 12.31+/-0.99. 2. The onset of menarche occurred at SNIT 7 and SNII 8 (73.33%). The onset of menarche was correlated with skeletal age rather than chronological age. 3. There was statistically significant difference among the time passed from menarche according to skeletal maturity level. 4. The distal epiphyseal union of radius began at about 20 months after menarche. 5. In comparision of the time intervals from menarche to radial epiphyseal fusion among early, average, and late menarcheal age groups, late group had lesser time interval than other two groups.

In order to correct a maxillofacial-skeletal disharmony successfully and achieve a favorable facial profile, orthodontic treatment must begin at pubertal growth spurt. Therefore predicting the pubertal growth pattern and evaluating the growth potential is very important For an orthodontist, estimating skeletal maturity in relation to one's personal growth spurt is essential and it must be considered into the treatment. The objective of this study was to find out whether there was a difference in menacheal age among different malocclusion groups and to evaluate the skeletal maturity at menarche. The subjects were 64 Class I malocclusion patients, 51 Class 1I patients and 38 Class III patients. Skeletal maturity was estimated from handwrist radiographs of these patients. Handwrist radiographs were taken between 3 months before and after the menarche. The results were as follows. 1. The mean chronologic age of menarche was 12.50+/-1.01 years. 2. For the Class I malocclusion group the mean age cf menarche was 12.36+/-1.04 years, for Class II 12.81+/-1,03 years and for Class III 12.32+/-0.82 years. According to these results Class II malocclusion patients started mensturation later than Class I and. Class III malocclusion patients. 3. No difference was found considering the skeletal maturity at menarche among the malocclusion groups. 4. The skeletal maturity index at menarche was SMI 7 for 45.10%, SMI 8 for 27.25%, SW 9 for 10.46%, SMI 6 for 7.84%, SMI 10 for 7.84% and SMI 5 for 1.31% patients. 5. Statistically there was a significant correlation between skeletal maturity estimated by handwrist radiographs and menacheal age( P<0.05, r-0.25430).
