Gonadotropin hormone-releasing hormone (GnRH) is the major regulator of the reproductive axis.  GnRH stimulates the anterior pituitary gland to release luteinizing hormone (LH) and follicle-stimulating hormone (FSH), which in turn activate the gonads to produce sex steroids. Thelarche is stimulated by estrogen and is usually the first sign of puberty in girls. Adrenarche, although associated temporally with puberty, is mediated by the adrenal cortex and is unrelated to pubertal maturation. A growth spurt occurs mid-puberty.  Menarche, usually occurring 2-3 years after thelarche, is considered the end of puberty. After menarche, only about 1-2 additional inches of height are accrued.  Understanding what is considered the normal timeline of sexual development allows better recognition of precocious or delayed puberty, both of which may be associated with serious underlying health issues\u0000This review contains 4 tables, 5 figures, and 29 references.\u0000Keywords: puberty, pubertal development, hypothalamic-pituitary-gonadal axis, thelarche, menarche, normal sexual development","PeriodicalId":120074,"journal":{"name":"DeckerMed Obstetrics and Gynecology","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-07-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125432330","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Preterm Premature Rupture of Membranes Preterm胎膜过早破裂

{"title":"Preterm Premature Rupture of Membranes","authors":"D. Castro, E. Norwitz","doi":"10.2310/OBG.19056","DOIUrl":"https://doi.org/10.2310/OBG.19056","url":null,"abstract":"Preterm premature rupture of membranes (PPROM) refers to rupture of the fetal membranes prior to 37-0/7 weeks’ gestation and prior to the onset of labor. PPROM complicates 2-4% of singleton pregnancies and 7-20% of twin pregnancies, and has been implicated in 30-40% of preterm births. Antepartum management involves confirming the diagnosis, excluding contraindications to expectant management (such as stillbirth, nonreassuring fetal testing, and intrauterine infection), and continued inpatient care with perinatology/NICU consultation, antenatal corticosteroids, broad-spectrum antibiotics (to prolong latency), and serial fetal surveillance. Delivery is indicated in the setting of nonreassuring fetal testing, intrauterine infection, excessive vaginal bleeding, preterm labor, and/or a gestational age of 34 weeks or beyond. Latency (time from rupture of membranes to delivery) depends on gestational age, severity of oligohydramnios, number of fetuses (shorter in twins), pregnancy complications (placental abruption, infection), fetal wellbeing, and use of broad-spectrum antibiotics. PPROM cannot be accurately predicted or prevented. Appropriate evidence-based management is essential to optimize outcome for both the mother and fetus in the setting of PPROM.\u0000This review contains 1 table, 2 figures and 57 references.\u0000Key words: chorioamnionitis, preterm birth, perinatal morbidity, twin pregnancies, preterm premature rupture of membranes (PPROM), fetal complications, maternal complications, labor and delivery, inpatient care, antepartum management","PeriodicalId":120074,"journal":{"name":"DeckerMed Obstetrics and Gynecology","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-05-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134041436","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Recurrent UTI is defined by two or more symptomatic infections in the past 6 months or three or more symptomatic infections in the past 12 months where each UTI follows a complete resolution of the previous UTI. This review describes the risk factors, diagnosis, work-up and treatment, and prevention of recurrent UTIs. Prevention strategies can be divided into antimicrobial and nonantimicrobial strategies. Nonantimicrobial prevention with behavioral changes, cranberry products, or probiotics did not significantly reduce the occurrence of symptomatic UTIs. Compared with placebo, oral estrogens did not reduce UTIs. However, vaginal estrogens do play a role in prevention of recurrence, particularly in postmenopausal women. There are three main strategies for antibiotic prevention: (1) low-dose daily antimicrobial prophylaxis, (2) postcoital antimicrobial prophylaxis, and (3) patient-initiated antimicrobial treatment. All of these strategies decrease infections during prophylaxis period.The choice of regimen should be based on susceptibilities and antibiotic allergy.\u0000\u0000This review contains 1 figure, 7 tables and 37 references.\u0000Keywords: antimicrobial prophylaxis, continuous antibiotics, CT urography, cystoscopy, postcoital prophylaxis, recurrent UTI, risk factors, self-directed therapy, treatment and diagnosis","PeriodicalId":120074,"journal":{"name":"DeckerMed Obstetrics and Gynecology","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-03-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116138883","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The Puerperium

Ricciotti","doi":"10.2310/obg.19030","DOIUrl":"https://doi.org/10.2310/obg.19030","url":null,"abstract":"The puerperium starts after the birth of a baby and continues until 6 to 8 weeks postpartum. Several recent interventions in management have been shown to improve outcomes. Delayed cord clamping, the practice of waiting for a period of time after a baby is born before clamping and cutting the umbilical cord, can increase hemoglobin levels, improve iron stores, and increase birth weight in newborns. Rooming in, the practice of mothers and newborns staying together, improves infant sleep and breast-feeding without affecting maternal sleep. Immediately after birth, significant physiologic and anatomic changes occur. Thromboembolic events are more common in the postpartum state than during pregnancy, but the majority of women do not require specific thromboprophylaxis but should be encouraged to walk after birth. Women who have not been previously immunized for influenza; tetanus, diphtheria, pertussis (Tdap); and rubella should be offered these immunizations. Women with uncomplicated pregnancies may engage in exercise within days after delivery. Pelvic floor physical therapy performed during pregnancy and postpartum may assist in maintaining or regaining muscle tone of the pelvic floor and may prevent or treat urinary incontinence. Perinatal depression affects one in seven women. Baby blues, which include mood swings, anxiety, tearfulness, and insomnia, should resolve by 2 weeks after delivery. Patients should be screened for depression using a standardized, validated tool and appropriate treatment initiated. All women should undergo a comprehensive postpartum visit within 6 weeks of delivery.\u0000 \u0000This review contains 2 figures, 4 tables and 34 references\u0000Key words: delayed cord clamping, hemodynamic changes, perinatal depression, postpartum, puerperium, rooming in, skin-to-skin contact\u0000 ","PeriodicalId":120074,"journal":{"name":"DeckerMed Obstetrics and Gynecology","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-02-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122371078","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
