A neglected Mayan galactagogue - ixbut (Euphorbia lancifolia).

A herbal tea, made of leaves of ixbut (Euphorbia lancifolia Schlecht.), has been used for several centuries by postpartum Mayan women in Guatemala to stimulate and increase the flow of mother's milk. Ixbut, when mixed with cattle fodder, is reputed to have increased milk yields in cows. To date, the active principle of ixbut has never been isolated. However, this medicinal herb, a natural galactagogue of Central American origin, would appear to be worthy of further chemical and pharmacological study. The following illustrated article describes the history and use of ixbut, and includes chromatographic analyses of dried ixbut leaves from Guatemala.

Does continuing oral magnesium supplementation until delivery affect labor and puerperium outcome?

OBJECTIVE: To determine the labor and puerperal impact of continuing oral magnesium supplementation until delivery. STUDY DESIGN: Single-center study with matched controls. In 40 pairs of healthy women with vaginally delivered singleton pregnancies, matched for maternal age, race and parity, maternal and neonatal outcome endpoints were compared in those receiving continuous oral magnesium aspartate supplementation 15-30 mmol/d for at least 4 weeks until delivery (for constipation, calf cramps, preterm contraction without cervical effacement or additional tocolytics) versus non-supplemented controls. RESULTS: In the magnesium group labor was nonsignificantly longer (stage 1: 326.0+/-187.5 min versus 276.7+/-140.8 min, P = 0.19; stage 2: 52.0+/-44.5 min versus 43.5+/-44.0 min, P = 0.40) and maximum oxytocin dose nonsignificantly higher (14.5+/-9.4 [median 12.0; n=15] versus 10.5+/-6.9 [median 7.5] mU/min, P = 0.28; n = 10). Fewer women had afterpains (12 versus 20, P=0.11), required spasmolysis (3 versus 14, P = 0.005), or could breastfeed their infants exclusively at discharge (24 versus 34, P = 0.04). CONCLUSION: Continuing oral magnesium supplementation until delivery does not significantly prolong labor or increase the oxytocin requirement, but it significantly impairs breastfeeding competence.

Delayed lactogenesis II: a comparison of four cases.

Lactogenesis II is the onset of copious milk production (i.e., the milk "coming in"), which usually occurs between 30 to 40 hours postpartum. When lactogenesis II fails to occur or is delayed, it may be due to a number of underlying hormonal or non-hormonal conditions. Of the various hormonal etiologies, many can be identified with the aid of a few standard blood tests. Gestational ovarian theca lutein cysts may cause delayed lactogenesis II and are fairly easily detected by ordering testosterone levels. Although this condition can delay lactogenesis II for as long as 31 days, with proper management women affected by these cysts have established breastfeeding. Three of the four women reviewed in this article were eventually able to produce 100% of their infants' caloric requirements.

A specific PCR for the detection of Mycoplasma putrefaciens, one of the agents of the contagious agalactia syndrome of goats.

Mycoplasma putrefaciens is listed as one of the etiologic agents of the contagious agalactia syndrome by the world organisation for animal health. This species has been characterized only recently, 1974, and the number of outbreaks caused by this microorganism so far is very scarce. It induces mastitis in infected goats although other symptoms such as arthritis in adults and septicaemia in kids are also frequently described. Up to now, the identification of M. putrefaciens relied on classical isolation and identification techniques which present a number of limitations. Specific primers for PCR have been designed based on sequence comparisons of the ArcB gene among the 'Mycoplasma mycoides cluster' and related species such as Mycoplasma cottewii and Mycoplasma yeatsii. Sequence alignments confirmed the taxonomic position of M. putrefaciens, which is related to the 'M. mycoides cluster' but also very close to M. yeatsii. The polymorphism observed amongst the different ArcB sequences allowed the determination of a primer pair yielding a specific amplification of a 316 bp-long DNA fragment by PCR. This PCR was validated in two different laboratories with a variety of mycoplasma strains isolated from goats. This new PCR technique will be very useful for a quicker determination of M. putrefaciens strains as well as a better understanding of the prevalence of M. putrefaciens infections.

In vitro susceptibilities of field isolates of Mycoplasma mycoides subsp. mycoides large colony type to 15 antimicrobials.

In vitro susceptibilities of 16 Mycoplasma mycoides subsp. mycoides large colony type field isolates to 15 antimicrobial agents were determined using a broth microdilution method. The most effective antimicrobials were fluoroquinolones, tetracyclines and macrolides, with MIC values under 2 microg/ml. Resistance to nalidixic acid, gentamicin, streptomycin and spectinomycin was observed.

Identification of risk factors for delayed onset of lactation.

OBJECTIVE: To identify infant feeding, socioeconomic, demographic, and delivery-related factors that affect women's self-reported timing of the onset of lactation. DESIGN: Longitudinal survey of women from day 1 postpartum until self-reported onset of lactation. Subjects were interviewed in person on day 1 postpartum, then surveyed daily by telephone regarding infant feeding method, breast symptoms, and perception of whether the onset of lactation had occurred. Medical records were reviewed. SUBJECTS/SETTING: Data were collected from 192 women after they gave birth to a healthy, term singleton. STATISTICAL ANALYSES PERFORMED: chi 2 Analyses were used to identify variables associated with delayed onset of lactation (onset of lactation > or = 72 hours postpartum). Multivariate logistic regression was used to identify the independent association of each significant variable with delayed onset of lactation. RESULTS: Risk factors for delayed onset of lactation included white/Hispanic ethnicity, heavy/obese body build, delivery of offspring by unscheduled cesarean delivery, vaginal delivery with prolonged stage 2 labor, infant birth weight less than 8 lb, and exclusive formula-feeding before the onset of lactation. APPLICATIONS/CONCLUSIONS: Women who are at risk for delayed onset of lactation need additional breast-feeding support during the first week postpartum. During their hospitalization, these women should be instructed about the normal lactation process and the possibility that onset of lactation may occur later than 72 hours postpartum. Frequent nursing should be recommended, as delayed onset of lactation was associated with the lack of infant suckling.

Regression of pituitary microadenoma during and following bromocriptine therapy: persistent defect in prolactin regulation before and throughout pregnancy.

During 5 years of clinical, endocrinologic, and radiologic observations in a woman with a microprolactinoma treated medically with bromocriptine for 29 months, serial hypothalamic-pituitary studies revealed a defect in lactotrope function after prolactin (PRL) concentrations and ovulation were restored to normal. This defect persisted throughout a spontaneously conceived pregnancy in which the PRL, estradiol, and progesterone levels were subnormal, while, the dehydroepiandrosterone sulfate levels were normal and estriol concentrations were elevated. Levels of the beta subunit of human chorionic gonadotropin (hCG) were close to and slightly above the normal ranges. These observations are consistent with a role for PRL, interacting with hCG, in the control of estrogen and progesterone secretion by the fetoplacental unit. Lactation was initiated and maintained post partum. Pituitary function and PrL responses to suckling suggested improved lactotrope function 22 to 25 months after withdrawal of bromocriptine. The impaired lactotrope function, therefore, did not preclude normal implantation, pregnancy maintenance, onset of parturition, fetal development, and lactation.

Prolactin-secreting pituitary adenomas in women. II. Menstrual function, pituitary reserves, and prolactin production following microsurgical removal.

A prospective study of 46 women with prolactin-secreting pituitary adenomas and amenorrhea and/or galactorrhea was performed to determine the influence of the selective transsphenoidal removal of these tumors on pituitary and reproductive function. This procedure was effective in restoring menstrual function in 34 of 41 women and in eliminating lactation in 30 of 40 women. Tumor size and preoperative serum prolactin concentrations were the most important factors in predicting the postoperative disappearance of symptoms. Normal menstrual function returned in 33 of 34 women with tumors less than 2 cm in diameter but in only one of seven women with tumors greater than 2 cm. Similarly, galactorrhea disappeared in 29 of 34 women with tumors less than 2 cm but in only one of six women with larger tumors. Menses returned in 31 of 32 women and galactorrhea disappeared in 25 of 31 women with preoperative serum prolactin levels below 200 ng/ml; conversely, menses returned in only three of nine women and lactation ceased in one of six women with preoperative serum prolactin concentrations above 200 ng/ml. Prolactin concentrations decreased in 42 of 43 patients following the removal of pituitary adenomas and returned to normal in 30. Postoperative pituitary reserves of adrenocorticotropic hormone, growth hormone, luteinizing hormone, and follicle-stimulating hormone were normal in most patients. These data indicate that the removal of prolactin-secreting pituitary adenomas by a neurosurgeon accomplished in this surgical technique is effective in restoring menstrual function and eliminating lactation in most women, especially if the tumor is less than 2 cm in diameter and the preoperative serum prolactin concentration is less than 200 ng/ml.

Clinical, biochemical, and radiologic reversibility of hyperprolactinemic galactorrhea-amenorrhea and abnormal sella by thyroxine in a patient with primary hypothyroidism.

A case of primary hypothyroidism associated with postpartum galactorrhea-amenorrhea is reported. The configuration of the sella was compatible with pituitary adenoma, but prolactin dynamics did not support an autonomous secretory state. Replacement therapy with thyroxine led to complete reversal of clinical, radiologic, and biochemical abnormalities.

Recurrence odds ratios for periparturient diseases and reproductive traits of dairy cows.

The recurrence odds ratios were calculated for a number of periparturient diseases and reproductive traits from 1490 pairs of successive lactations in dairy cattle. Vulval discharge, oestrus not observed and mastitis diagnosed before service had summary recurrence ratios of 1.39, 1.37 and 1.49 respectively, all statistically significant at the 5% level. Retained foetal membranes and calf mortality had higher summary risk ratios of 1.84 and 1.76 respectively, but were not significant at the 5% level. Whilst the number of services per conception did have a recurrence ratio above 1, the result was not significant at the 5% level.
