Menarche stories: reminiscences of college students from Lithuania, Malaysia, Sudan, and the United States.
Women college students in four countries were invited to write the story of their first menstruation in as much detail as memory allowed. Stories were received from 26 Lithuanians, 27 Americans, 20 Malaysians, and 23 Sudanese. The stories were read and their contents analyzed for the presence or absence of information on such topics as emotional reaction, preparedness, sources of information about menstruation, changes in body image, and celebrations of this rite of passage. Similarities and differences among the groups are discussed, and passages from particularly interesting stories are quoted.

Menstruation and control of diabetes.
Seventy per cent of the patients aged 45 years or under and suffering from diabetic ketoacidosis who were seen in one diabetic clinic over five years were women. The association of menstruation with ketoacidosis was assessed over two and a half years, and it was found that menstruation was associated with ketoacidosis more often than would be expected by chance (P less than 0-01). Two hundred women were interviewed and 76 observed that menstruation changed their diabetic control. Fifty-three found that control deteriorated and hyperglycaemia occurred, while 23 found that control improved and hypoglycaemia was a common problem. Menstruation appears to be an important factor in influencing control of diabetes. The mechanism of the changes observed has not yet been determined, but it seems to be a subject worthy of further investigation.

[On the position of the human foetus and the probability of spontaneous change in position during pregnancy (author's transl)].
Since ultrasonic examinations became routine practice in pregnancy rather often breech presentations are being found in the course of pregnancy. The amounts of breech, vertex presentation and cross position in the course of pregnancy are shown in a curve which is made from 2.240 single measurements. There are significant differences between primiparae and multiparae as to the frequency of breech and vertex presentation. The analysis of all repeated determinations of fetal presentations allows predications about the probability of changing of a breech into a vertex presentation and vice versa in a determined week of pregnancy. For example the probability of the turning of a breech presentation into a vertex presentation is 44.6% in the 29th week post menstruation, 23.2% in the 33rd week post menstruation. From the 37th week onwards the fetus won't turn any more into the vertex presentation. A vertex presentation, for example in the 29th week post menstruation changes into a breech presentation with a probability of only 0.55%. From the 33rd week onwards a turn into a breech presentation is no longer to be expected. A diagram for the probabilities of the fetal presentations' turnings into the opposite presentations is given for the 13.-40. week post menstruation, from which the patient can immediately be informed about the individual chance. The turn into the vertex presentation is the most common one and seems to be the physiologic one. This turn occurs more or less constantly, not abruptly.

Menstrual patterns and progesterone circulating levels following different procedures of tubal occlusion.
This study was undertaken to assess the effects of different tubal occlusion procedures on ovarian function. Three groups of subjects randomized to tubal occlusion by laparoscopy and Yoon ring (24 subjects), minilaparotomy and Yoon ring (19 subjects) and minilaparotomy and Pomeroy (22 subjects), and one separate control group of 26 healthy subjects not using any form of contraception were studied in a prospective design. The characteristics of the menstrual patterns were studied for one year after sterilization. Determination of the circulating progesterone levels were made on days 15, 20 and 25 of menstrual cycles initiated 1, 3, 6 and 12 months following the tubal ligation. In the analysis of the bleeding pattern there was a statistically significant difference in the mean segment length and in the longest bleeding-free interval in the subjects who had been sterilized by minilaparotomy with Yoon ring, when compared to the other two study groups and to the control group. However, the magnitude of this difference in number of days was not considered clinically significant. There was no statistically significant difference in the percentage of ovulatory cycles within the study and the control groups, or when the results of the study groups were compared with each other or to the control group.

Postponement of withdrawal bleeding with a monophasic oral contraceptive containing desogestrel and ethinylestradiol.
This study investigated the ability of a monophasic sub-50 oral contraceptive, containing desogestrel and ethinylestradiol, to postpone withdrawal bleeding in normal healthy women. In the analyzed group of 105 regular users of Marvelon, about 75% did not experience any vaginal bleeding during the 21 days of postponement. A 95% confidence interval was calculated which suggests that the percentage of women able to postpone their withdrawal bleeding successfully for 19 days ranges between 67.0% and 83.5%. Women with no vaginal blood loss in the postponement period were more willing to try this method of postponement again, compared to women who experienced vaginal blood loss in the postponement period. This difference was statistically significant. Nevertheless, the majority of women with vaginal blood loss were also willing to try this method again if necessary. The study results suggest that Marvelon offers an effective and acceptable method of postponing withdrawal bleeding for three weeks for most regular users of this contraceptive.

The influence of a low-dose combined oral contraceptive on menstrual blood loss and iron status.
The influence of a low-dose combined oral contraceptive (ethinyl estradiol 30 micrograms + desogestrel 0.15 mg) on menstrual blood loss (MBL) was evaluated in 20 healthy, young women. MBL prior to commencing oral contraception was 60.2 +/- 5.6 ml (range 22-116 ml), and decreased (p < 0.001) to 36.5 +/- 5.2 ml (range 7-80 ml) and 33.7 +/- 4.1 ml (range 5-70 ml) after 3 and 6 months' oral contraceptive medication, respectively. The reduction in MBL during oral contraception was most apparent during the first two days of menstruation. Five women had an MBL > 80 ml prior to commencing oral contraceptive medication. In all of these women, MBL during the 6th menstrual period after commencing oral contraception was < 80 ml. All the women included in this study had a normal blood hemoglobin concentration, hematocrit and erythrocyte indices and there were no significant changes in these variables during the course of the study. Serum ferritin concentration prior to commencing oral contraception was 44.2 +/- 9.0 micrograms/l and was largely unchanged after 6 months' oral contraception (39.7 +/- 6.3 micrograms/l). On admission to the study, two women had a serum ferritin < 10 micrograms/l, indicative of low iron stores. Both these women had an MBL > 80 ml at the baseline assessment. Serum ferritin concentration increased during oral contraceptive medication in both women (from 8.5 micrograms/l to 12.0 micrograms/l and from 5.4 micrograms/l to 6.8 micrograms/l, respectively). The duration of menstruation (p < 0.01) and the number of women suffering from dysmenorrhea (p < 0.05) was reduced during oral contraception.

A comparison of flurbiprofen, tranexamic acid, and a levonorgestrel-releasing intrauterine contraceptive device in the treatment of idiopathic menorrhagia.
Treatment with flurbiprofen (100 mg twice a day for 5 days), tranexamic acid (1.5 gm three times a day for 3 days and 1 gm twice a day for another 2 days), and an intrauterine contraceptive device releasing 20 micrograms levonorgestrel per day was compared in women with idiopathic menorrhagia. The menstrual blood loss during two control periods in 15 women subsequently treated with flurbiprofen and tranexamic acid was 295 +/- 52 ml and 203 +/- 25.2 ml in the 16 women later fitted with a levonorgestrel-releasing intrauterine contraceptive device. Menstrual blood loss was reduced by all three forms of treatment. The reduction in menstrual blood loss expressed as a percentage of the mean of two control cycles for each form of treatment was as follows: flurbiprofen, 20.7% +/- 9.9%; tranexamic acid, 44.4% +/- 8.3%; levonorgestrel-releasing intrauterine contraceptive device after 3 months, 81.6% +/- 4.5%; levonorgestrel-releasing intrauterine contraceptive device after 6 months, 88.0% +/- 3.1%; levonorgestrel-releasing intrauterine contraceptive device after 12 months, 95.8% +/- 1.2%. The reduction in menstrual blood loss achieved by the levonorgestrel-releasing intrauterine contraceptive device was greater than that recorded with flurbiprofen (p less than 0.001) and tranexamic acid (p less than 0.01), and was greater for tranexamic acid when compared with flurbiprofen (p less than 0.05). The levonorgestrel-releasing intrauterine contraceptive device was the only form of treatment to reduce mean menstrual blood loss below 80 ml per menstruation, the upper limit of normal menstrual blood loss.

Seasonality of reproductive function and weight loss in rural Nepali women.
Menstrual and hormonal disturbances have been reported in thin, dieting and exercising Western women, and also recently in rural African women. A study of salivary progesterone profiles was undertaken in a Nepali population to examine whether seasonal increases in workload and changes in energy balance influenced ovarian function. Women's energy expenditure levels were moderately heavy in the winter and very heavy in the monsoon, and body mass fluctuated by -2.8 to +4.8 kg. Samples were collected from 24 normally menstruating women in two seasons, each individual serving as her own control. Progesterone levels were significantly depressed in the monsoon relative to winter for women who lost weight, but not for women who gained weight, indicating that energy imbalance is associated with a loss of fecundity. No differences in body mass index were found between women who lost or gained weight. Progesterone levels were age-dependent, and the degree of hormonal disturbance between age-groups was related to weight loss. The study demonstrates seasonal changes in the fecundity of hard-working Nepali women and a direct link between ovarian function and weight loss (negative energy balance), which is independent of current nutritional status.

Post-tubal sterilization syndrome.
This article presents a review of the literature on post-tubal sterilization syndrome. Although studies have shortcomings they suggest the majority of women undergoing tubal sterilization do not experience changes in menstrual patterns after the procedure, but a minority do. Suggestions are made for further research, conducted from a nursing perspective. Implications for practice are suggested, given the tentative information on post-tubal sterilization syndrome.

Menstrual patterns after female sterilization: variables predicting change.
Previous studies of the changes in menstrual pattern characteristics following sterilization have been flawed by methodologic errors. As a result, contradictory findings have been reported. Appropriate methodologic approaches to the study of poststerilization menstrual patterns are presented, and a new methodologic approach-an index of menstrual pattern change-is offered, which evaluates four menstrual parameters simultaneously. A carefully controlled study using this index indicates that most women report no change in menstrual pattern at 12 months poststerilization, and among those who do experience change, changes in one direction are balanced by changes in the other direction. The changes reported include improvements as well as changes for the worse. The best predictor of whether a woman would experience menstrual pattern change after sterilization is whether her pattern had any abnormal characteristics during the three months prior to the procedure. Surgical variables and special subgroups of women are also evaluated.
