Histologic dating of the endometrium: accuracy, reproducibility, and practical value

By Vilma Ruddock M. It is normal to have cyclic menstrual bleeding at the end of a packet of birth control pills or other hormonal contraception. Some women, however, might experience irregular, or breakthrough vaginal uterine bleeding on these types of birth control. Other birth control methods can also cause irregular bleeding. Vaginal Bleeding on Birth Control Pills Monthly menstruation is the normal pattern of vaginal bleeding with traditional birth control pills. Any other pattern or type of bleeding is abnormal uterine bleeding , or breakthrough bleeding. The irregularity of the pattern depends on how your uterine lining endometrium responds to the hormones in the pill. Cyclic Menstrual Bleeding The conventional birth control pills reproduce regular, normal menstrual bleeding – which tends to be lighter and shorter.

Causes of Vaginal Bleeding While on Birth Control

References Progesterone Support in Pregnancy [Figure , p. Furthermore, most of the assessment of progesterone in pregnancy as it relates to various complications of pregnancy was accomplished from the early s through the early s. In spite of improvements in the accuracy and precision of progesterone assays since that time and a better ability to date pregnancy and establish more accurate gestational ages, very little subsequent work has been accomplished in this area. However, data on the level of progesterone in normal pregnancy, and as it relates to a variety of pregnancy-related complications and features of previous reproductive history has been generated in a study which was conducted from the years through at the Pope Paul VI Institute.

Modern means of progesterone assessment with improved accuracy and precision were used along with more precise means of dating the pregnancies.

Sometimes a saline sonohysterogram may be suggested to better view the endometrium and any suspected problems.

It is asserted that examination of the endometrium during the secretory phase yields more information about the time of ovulation, degree of progestational change, and normality of the endometrium than any other test used in sterility studies. Attention to qualitative changes in 8 morphological factors is most useful in dating the endometrial biopsy. During the 1st week of luteal activity, attention should be focused on changes occurring in gland epithelium: During the 2nd week , stromal changes including edema , predecidual reaction, stromal mitosis, and leukocytic infiltration are the key criteria.

Tissue from the fundus of the uterus gives the most reliable information. These critera were used in sterility biopsies taken from normally menstruating women over a 3-year period. Absence of organic endometrial disease and availability of accurate menstrual history were the only selection criteria. To test the validity of the dating criteria, change in basal body temperature was used to correlate endometrial dating with ovulation rather than onset of menstruation. To determine whether biopsy caused early menstruation, the secretory phases of the 25 patients who had recorded temperatures in at least 2 cycles in addition to that in which the biopsy was taken were examined.

The secretory phase was definitely shorter in the biopsied than control cycle, suggesting that biopsy does accelerate the onset of flow.

La diminuzione del pH favorisce la proliferazione dei batteri gram-negativi Due possibili quadri di patologia orale possono essere identificati nella donna in gravidanza: In particolare Prevotella intermedia ha un notevole incremento nelle donne in gravidanza Diversi studi hanno dimostrato le funzioni immunosoppressive degli ormoni durante la gravidanza.

Ha generalmente una forma rotondeggiante raggiungendo anche il volume di una ciliegia. Per quanto riguarda la sua istogenesi si ritiene che il mesenchima del legamento alveolo-dentale sia il punto di partenza. In passato si pensava che la forte incidenza della carie nella gravida fosse dovuta a sottrazione di sali minerali, costituenti importanti di smalto e dentina, da parte del feto per il suo necessario sviluppo.

In sede di applicazione, a dosi terapeutiche, non provoca fenomeni irritativi locali. I vasocostrittori possono indurre direttamente contrazioni uterine e ipossia fetale mediante vasocostrizione dei vasi placentari con efficacia dose-dipendente. Nella specie umana, indagini condotte per esposizioni prolungate e ripetute superiore alle nove ore alla settimana hanno evidenziato un aumento di aborti spontanei tra le mogli di dentisti e un aumento di anomalie congenite e aborti nelle assistenti alla poltrona; non esiste, comunque, dimostrazione che singole esposizioni inferiori a 30 minuti si associno a rischio significativo.

First trimester ultrasound is performed in the first months of a pregnancy. Pregnancy ultrasounds are performed mainly using transabdominal ultrasound. For many women, especially after 8 weeks gestation, sufficient information about the baby may be obtained with transabdominal ultrasound only.

Penicillin and other antibiotics that inhibit cell wall synthesis and sulfonamides do not inhibit genital mycoplasmas.

Transvaginal ultrasound is performed using a special transducer which is slightly thicker than a tampon. It is covered with a disposable latex sheath and lubricating gel, then gently placed into the vagina. The probe sits in the vagina throughout the examination which usually takes between minutes. Most patients find the examination much more tolerable when compared to a cervical PAP smear.

During the scan the sonographer may need to gently press on the abdomen to move bowel out of the way and bring the ovaries and other pelvic structures into view. This also enables any point of tenderness in the pelvis to be identified. Transvaginal or transabdominal ultrasound: Is there a choice? It is a Sydney Ultrasound For Women protocol to offer transvaginal assessment for all Gynaecological and early pregnancy scans.

This is because the transducer is positioned close to the pelvic structures, producing superior image quality, hence, the most detailed and accurate diagnosis. Though a SUFW protocol to offer an internal scan, patients may decline and instead be scanned transabdominally. In certain circumstances a transvaginal ultrasound examination is not possible or not advisable eg.

A pelvic or gynaecologic ultrasound is an ultrasound of the female pelvis. Most pelvic ultrasounds are performed using both the transabdominal and transvaginal approaches. Transabdominal ultrasound involves scanning through your lower abdomen. Transabdominal ultrasound usually provides an overview of the pelvis rather than detailed images. The transabdominal assessment is particularly helpful for the examination of large pelvic masses extending into the abdomen, which are not always well viewed with transvaginal ultrasound.

A small amount of ultrasound gel is put on the skin of the lower abdomen, with the ultrasound probe then scanning through this gel.

Please inform the sonographer at the beginning of the ultrasound if you:
