Celiac disease is a genetically-based intolerance to gluten. In the past, celiac disease has been considered a rare disease of infancy characterized by chronic diarrhea and delayed growth. Besides the overt enteropathy, there are many other forms which appear later in life; target organs are not limited to the gut, but include liver, thyroid, skin and reproductive tract. It is now recognized that celiac disease is a relatively frequent disorder; the overall prevalence is at least 1:300 in Western Europe. Celiac disease may impair the reproductive life of affected women, eliciting delayed puberty, infertility, amenorrhea and precocious menopause. Clinical and epidemiological studies show that female patients with celiac disease are at higher risk of spontaneous abortions, low birth weight of the newborn and reduced duration of lactation. No adequate studies are available on the rate of birth defects in the progeny of affected women; however, celiac disease induces malabsorption and deficiency of factors essential for organogenesis, e.g. iron, folic acid and vitamin K. The overall evidence suggests that celiac disease patients can be a group particularly susceptible to reproductive toxicants; however, the pathogenesis of celiac disease-related reproductive disorders still awaits clarification. At present, like the other pathologies associated with celiac disease, the possible prevention or treatment of reproductive effects can only be achieved through a life-long maintenance of a gluten-free diet.

Women with transfusion dependent thalassaemia suffer from failure of pubertal growth and delayed onset of menarche with amenorrhea, anovulation and infertility. With improved pediatric and hematological care is now possible, for patients with b thalassaemia, to achieve a pregnancy. Pre-pregnancy assessment included checks for hypothyroidism and diabetes, for hepatitis B and C, human immunodeficiency virus, Rubella, cardiac functions, liver functions by estimating aspartate and alanine aminotransferases, gamma-glutamyl transpeptidase, alkaline phospatase, and total plasma proteins. The frequency of blood transfusion needed to be increased in order to maintain the hemoglobin concentration above 10 g/dl. Desferroxamine must be stopped as soon as pregnancy is diagnosed continuing the administration of the folic acid supplements throughout pregnancy. Desferroxamine will be resumed after delivery. The safety of iron chelation with desferroxamine during the periconceptional period and pregnancy has not yet been established. Some animal studies have shown skeletal anomalies; other published studies report seven women with b thalassaemia major who became pregnant while taking desferroxamine: all the women had normal babies. The mode of delivery is usually vaginal, while Cesarean section is performed in those cases with pre-eclampsia, fetal distress, cephalopelvic dysproportion, slow progression of labor, as in women without thalassaemia. In conclusion, with the advent of regular blood transfusion associated with iron chelation therapy, pregnancy in b thalassaemia can be safe for mothers and their babies with appropriate care.

To report the frequency and intensity of anemia in a population of pregnant tunisian women. Our retrospective study concern 200 patients collected from january to july 1999 in a population of pregnancies. Mean age was 30.1 years and 68.5% of patients consult in the third trimester with a 33.5% rate of multiparity. The frequency of anemia is 37.5%. Anemia was ferriprive in 97.3% and hypochromic in 24% of cases. Mean ferritinemia is 4.19 ng/ml after 24 weeks of amenorrhea with a marqued decrease in case of multiparity and pregnancy evolution. Mean transferrinemia is significantly low in anemic (3.98 g/dl) versus non anemic (3.60 g/dl) patients (< 0.05). The comparison of anemia with parity, the delay between two pregnancies and term of pregnancy showed a higher risk with multiparity, short delay between two pregnancies and advanced term. The frequency of anemia in tunisian pregnant women is relatively high, prevention is based on iron supplementation and hygienodietetic advices.

Changes in menstrual bleeding, the most common side effects of progestin-only contraceptives, can worry women, leading to discontinuation. In fact, menstrual disturbances comprise the main reasons for discontinuing progestin-only contraceptives. Before prescribing these contraceptives, providers should advise women that they are likely to experience changes in menstrual bleeding. They should also guide women to compare the benefits of the contraception with these side effects. The key to user satisfaction and continuation is counseling. Counseling should help women determine what they want and are able to do. The changes in menstrual bleeding for many women have cultural implications (e.g., bleeding restricts women's activities). Providers should first ascertain whether changes in menstrual bleeding are a side effect of progestin-only contraceptives or signify another condition. For example, prolonged bleeding is also a symptom of cancer. Once the provider has eliminated other conditions, he/she should explain to clients that users of progestin-only contraceptives commonly experience menstrual disturbance. Irregular or prolonged bleeding is common during the first 3-6 months of use, then tends to subside. Amenorrhea poses no medical reason to discontinue progestin-only contraceptives. When counseling does not reassure clients or when clients experience prolonged or heavy bleeding, providers can prescribe hormonal treatments and nonsteroidal, anti-inflammatory drugs: one low-dose combined oral contraceptive pill or estrogen once a day for 7-21 days or, if bleeding is more severe, once every 12 hours; 200 mg ibuprofen, or any nonsteroidal anti-inflammatories other than aspirin 3-4 times/ day. Some providers question whether estrogen or ibuprofen should be administered on top of progestin, since the double treatment may cause undesirable side effects. Also some women use progestin-only methods because they can not use estrogen. Iron supplements can treat women susceptible to anemia.

A survey of reproductive health activities in 50 countries shows that 25% of family planning programs provided all types of reproductive health services: family planning or safe regulation of fertility, maternal health and nutrition, protection from sexually transmitted diseases (STDs), and reproductive rights. Integrated reproductive health services reduce duplication and the number of workers and facilities needed. A program providing postpartum care and family planning services in Honduras and Peru increased contraceptive prevalence and saved money. Yet, combining new health services into a family planning program may strengthen one component while hurting the other. Health planners need to reflect on how to integrate reproductive health activities. Family planning providers can screen for STDs, distribute condoms, maintain hygienic facilities, and guarantee that contraceptive services or procedures do not spread or exacerbate genital tract infections. A simple way is needed to evaluate their clients' STD risk, such as interviewing clients about symptoms. At some family planning clinics in Brazil, a cartoon soap opera helps clients in small groups discuss STDs. Family planning clients tend to be married women who generally are not a high risk group. Providers should not recommend a contraceptive method without first determining the client's STD risk. Clients should not choose a method without first considering their STD risk. Family planning prevents maternal deaths. For example, a community project in rural Bangladesh increased contraceptive prevalence, which in turn contributed to a 33% decrease in maternal mortality. Family planning caregivers can tell women about prenatal care, pregnancy complications, and the benefits of breast feeding, as well as provide them with iodine and iron supplements, tetanus toxoid, and malaria prophylaxis. They can counsel postpartum mothers about birth spacing methods (e.g., lactational amenorrhea method).

All medications have side effects in certain patients; none is 100% "safe" and the physicain must determine the benefit-to-risk ratio of each contraceptive method for a particular patient. 81% of white, nonCatholic women aged 20-24 who are college graduates use oral contraceptives, an extraordinary acceptance level for a method not even available in 1960. The various preparations available in the U.S, amount of estrogen and progestogen in each, and side effects are then surveyed. Estrogen irritates the gastric mucosa and diminishes rate of sodium excretion by the kidneys; this causes the nausea, edema, general bloating, tension, and headaches which most commonly cause women to discontinue the medication. The patient with full breasts who menstruates normally should not be overloaded with estrogen while a high-estrogen compound might benefit the woman with small breasts and scanty menses. Estrogens are known stimulants for the growth of uterine leiomyomas; if such lesions are present an antiestrogenic progestogen is indicated. High estrogen pills are more likely to stimulate breast growth and increase discomfort from fibrocyctic disease while a progestin-dominant combination will reduce this discomfort. The "19-nor" progestins are essentailly variants of testosterone and may produce hirsutism, alopecia, acne, hypomenorrhea, or even amenorrhea. T hey also may increase appetite and cause excessive weight gain. The total effect is complicated by such factors as the particular progestin used. The 19-norsteroid compounds are partly metabolized to estrogen and increase the estrogenic effect while norgestrel produces antiestrogenic activity. Newer marketing methods have tried to simplify administration by inserting 7 iron tablets or 7 placebos so the user takes a pill every day for 28 days. For patients who have noted side effects during the 7-day interval they are not taking the pill (undoubtedly related to temporary estrogen insufficiency) .02 mg ethinyl estradiol may be used. The sequential method more closely simulates the normal menstrual cycle and can be used to advantage in women who suffer prolonged anovulation after cessaton of combination therapy and in women past 35 in whom the increased risk of pregnancy is offset by declining fertility potential. Both serious and minor adverse reactions to various forms of therapy are detailed. These include cutaneous, nervous system, metabloic, and endocrine system changes.

Exercise-induced or athletic menstrual dysfunction (amenorrhoea, oligomenorrhoea, anovulation, luteal phase deficiency, delayed menarche) is more common in active women and can significantly affect health and sport performance. Although athletic amenorrhoea represents the most extreme form of menstrual dysfunction, other forms can also result in suppressed estrogen levels and affect bone health and fertility. A number of factors, such as energy balance, exercise intensity and training practices, bodyweight and composition, disordered eating behaviours, and physical and emotional stress levels, may contribute to the development of athletic menstrual dysfunction. There also appears to be a high degree of individual variation with respect to the susceptibility of the reproductive axis to exercise and diet-related stresses. The dietary issues of the female athlete with athletic menstrual dysfunction are similar to those of her eumenorrhoeic counterpart. The most common nutrition issues in active women are poor energy intake and/or poor food selection, which can lead to poor intakes of protein, carbohydrate and essential fatty acids. The most common micronutrients to be low are the bone-building nutrients, especially calcium, the B vitamins, iron and zinc. If energy drain is the primary contributing factor to athletic menstrual dysfunction, improved energy balance will improve overall nutritional status and may reverse the menstrual dysfunction, thus returning the athlete to normal reproductive function. Because bone health can be compromised in female athletes with menstrual dysfunction, intakes of bone-building nutrients are especially important. Iron and zinc are typically low in the diets of female athletes if meat products are avoided. Adequate intake of the B vitamins is also important to ensure adequate energy production and the building and repair of muscle tissue. This review briefly discusses the various factors that may affect athletic menstrual dysfunction and two of the proposed mechanisms: the energy-drain and exercise-intensity hypotheses. Because energy drain can be a primary contributor to athletic menstrual dysfunction, recommendations for energy and the macro- and micronutrients are reviewed. Methods for helping the female athlete to reverse athletic menstrual dysfunction are discussed. The health consequences of trying to restrict energy intake too dramatically while training are also reviewed, as is the importance of screening athletes for disordered eating. Vitamins and minerals of greatest concern for the female athlete are addressed and recommendations for intake are given.

Nutritional status, eating behaviors and menstrual function was examined in 23 nationally ranked female adolescent volleyball players using a health/weight/ dieting/menstrual history questionnaire, the Eating Disorder Inventory (EDI), and the Body Shape Questionnaire (BSQ). Nutrient and energy intakes (El) and energy expenditure (EE) were determined by 3-d weighed food records and activity logs. Iron (Fe), vitamins C, B12, and Folate status were assessed using serum and whole blood. Mean El (2248 +/- 414 kcal/d) was less than EE (2815 +/- 306 kcal/d). Mean carbohydrate (5.4 +/-1.0g/kg/d) and protein (1.1+/-0.3g/kg/d) intakes were below recommended levels for highly active women. Mean intakes for folate, Fe, Ca, Mg, and Zn were less than the respective RDAs/DRIs and almost 50% of the athletes were consuming less than the RDAs/DRIs for the B-complex vitamins and vitamin C. Three athletes presented with Fe deficiency anemia (Hb <12 mg/dL), while marginal vitamin B12 status (<200 pg/ml) and vitamin C status (<28 mmol/L) were found in 1 and 4 athletes, respectively. Approximately 1/2 of the athletes reported actively "dieting". Mean BSQ and EDI subscales scores were within the normal ranges; yet, elevated scores on these scales were reported by 26% and 35% of athletes, respectively. Past or present amenorrhea was reported by 17% of the athletes and 13% and 48%, reported past or present oligomenorrhea and "irregular" menstrual cycles, respectively. These results indicate that elite adolescent volleyball players are at risk for menstrual dysfunction and have energy and nutrient intakes that place them at risk for nutritional deficiencies and compromised performance.

Adequate nutrition is essential during adolescence, since growth and development during this period play key roles in achieving normal adult size and reproductive capacity. This article briefly reviews recommended caloric intake; the healthy balance of carbohydrates, fat and protein; and the appropriate dietary intake of iron, folic acid and calcium for the adolescent. A major potential obstacle to good nutrition for an adolescent is the development of an eating disorder such as anorexia nervosa or bulimia nervosa. Anorexia nervosa, characterized by severe underweight, fear of gaining weight, and low self-esteem and amenorrhea, is associated with many physiological and psychological complications with which the provider must be familiar. Similarly, bulimia nervosa, which presents with eating binges followed by compensatory behaviors such as vomiting, diet pill abuse and overexercise, may be harder to detect, but can also have devastating consequences, both physically and emotionally, for a young person. Both of these disorders are best treated by a multidisciplinary team of specialists to address the medical, psychological, and nutritional components of these illnesses.

Although the health benefits of breastfeeding are acknowledged widely, opinions and recommendations are divided on the optimal duration of exclusive breastfeeding. We systematically reviewed available evidence concerning the effects on child health, growth, and development and on maternal health of exclusive breastfeeding for 6 months vs. exclusive breastfeeding for 3-4 months followed by mixed breastfeeding (introduction of complementary liquid or solid foods with continued breastfeeding) to 6 months. Two independent literature searches were conducted, together comprising the following databases: MEDLINE (as of 1966), Index Medicus (prior to 1966), CINAHL, HealthSTAR, BIOSIS, CAB Abstracts, EMBASE-Medicine, EMBASE-Psychology, Econlit, Index Medicus for the WHO Eastern Mediterranean Region, African Index Medicus, Lilacs (Latin American and Carribean literature), EBM Reviews-Best Evidence, the Cochrane Database of Systematic Reviews, and the Cochrane Controlled Trials Register. No language restrictions were imposed. The two searches yielded a total of 2,668 unique citations. Contacts with experts in the field yielded additional published and unpublished studies. Studies were stratified according to study design (controlled trials vs. observational studies) and provenance (developing vs. developed countries). The main outcome measures were weight and length gain, weight-for-age and length-for-age z-scores, head circumference, iron status, gastrointestinal and respiratory infectious morbidity, atopic eczema, asthma, neuromotor development, duration of lactational amenorrhea, and maternal postpartum weight loss. Twenty independent studies meeting the selection criteria were identified by the literature search: 9 from developing countries (2 of which were controlled trials in Honduras) and 11 from developed countries (all observational studies). Neither the trials nor the observational studies suggest that infants who continue to be exclusively breastfed for 6 months show deficits in weight or length gain, although larger sample sizes would be required to rule out modest increases in the risk of undernutrition. The data are conflicting with respect to iron status but suggest that, at least in developing-country settings, where iron stores of newborn infants may be suboptimal, exclusive breastfeeding without iron supplementation through 6 months of age may compromise hematologic status. Based primarily on an observational analysis of a large randomized trial in Belarus, infants who continue exclusive breastfeeding for 6 months or more appear to have a significantly reduced risk of one or more episodes of gastrointestinal tract infection. No significant reduction in risk of atopic eczema, asthma, or other atopic outcomes has been demonstrated in studies from Finland, Australia, and Belarus. Data from the two Honduran trials suggest that exclusive breastfeeding through 6 months of age is associated with delayed resumption of menses and more rapid postpartum weight loss in the mother. Infants who are breastfed exclusively for 6 months experience less morbidity from gastrointestinal tract infection than infants who were mixed breastfed as of 3 or 4 months of age. No deficits have been demonstrated in growth among infants from either developing or developed countries who are exclusively breastfed for 6 months or longer. Moreover, the mothers of such infants have more prolonged lactational amenorrhea and faster postpartum weight loss. Based on the results of this review, the World Health Assembly adopted a resolution to recommend exclusive breastfeeding for 6 months to its member countries. Large randomized trials are recommended in both developed and developing countries to ensure that exclusive breastfeeding for 6 months does not increase the risk of undernutrition (growth faltering), to confirm the health benefits reported thus far, and to investigate other potential effects on health and development, especially over the long term.
