What causes staph? Is it related to our daily life habits or is it transmitted by a virus? The following, I will start from what the gravida is, to explain for you one by one.
1. Staphylococcal fetus
The reason is that the microvasculature of the villi stroma disappears, thus the villi stroma accumulates fluid and forms vesicles of different sizes, shaped like grapes, so it is called a staphylococcal fetus. The majority of them are complete and partial.
2. Causes of staphylococcal fetus
The true cause of staphylococcal fetus is unknown. A case-control study found that the occurrence of staphyloma is related to nutritional status, socioeconomic and age. Age is a significant correlate in the etiology, with the incidence of staphylococytes being 10 times higher in women older than 40 years than in younger women, and age less than plus years is also a high risk factor for the occurrence of complete staphylococytes, with women at these two ages being prone to fertilization defects. Partial gravidity is not associated with maternal age.
Cytogenetic studies combined with pathological studies have demonstrated the genetic characteristics of each of the two types of staphylococytes. The chromosomal genome of the complete gravida is of paternal origin, i.e. the egg develops in the absence or inactivation of the oogenic nucleus and the spermatogonial nucleus.
3. Symptoms of staph
Menorrhagia
Because gravidity occurs in the trophoblastic layer of the pregnant egg, amenorrhea occurs for 2 to 3 months or longer.
Vaginal bleeding
This is a serious symptom and is a sign of spontaneous abortion of the gravida. It usually begins 2 to 3 months after amenorrhea and is mostly intermittent with a small amount of bleeding, but it can be interrupted by repeated heavy bleeding, sometimes with blistering in the bleeding if examined carefully. The vaginal bleeding apparently comes from the uterus and, in addition to flowing from the vagina, partially accumulates in the uterus; it may also accumulate completely in the uterus for a while, thus prolonging the amenorrhea.
Enlargement of the uterus
In most patients, the uterus is larger than that of the corresponding month of menopause, and many patients come to the clinic with a palpable lower abdominal mass (distended uterus or flavin cyst), but there are a few cases in which the uterus is consistent with or even smaller than the month of menopause.
Abdominal pain
The pain can be mild or severe due to the rapid enlargement of the uterus and distension, or intrauterine bleeding that stimulates uterine contractions.
Symptoms of pregnancy toxicity
About half of the patients may develop severe vomiting after menopause, and later on, hypertension, swelling and proteinuria.
No fetal accessibility
Ultrasound monitoring around 8 weeks of amenorrhea does not reveal any fetal sac, fetal heart and fetus. Ultrasound scans show snowflake-like images without fetal images.
Ovarian flavinized cysts
Ovarian flavinizing cysts are often seen in some patients and can be detected by duplex examination or more easily by ultrasound.
Hemoptysis
Some patients may have hemoptysis or blood in the sputum and the physician should ask for this symptom.
Anemia and infection
Untreated recurrent bleeding will lead to anemia and related symptoms and, in some cases, death due to bleeding. Repeated bleeding can easily lead to infection, which is facilitated by unclean vaginal practices or sexual intercourse during bleeding. Infection can be confined to the uterus and adnexa and can lead to sepsis.
