Pregnancy confirmation

Aloka Pro Sound SSD 4000 used for ultrasound examinations. For pregnancy confirmation, a 10 MHz linear probe (UST5542) is used. For fetal examinations, a 7.5 MHz probe (UST 5524) or 5 MHz convex probe (UST 992-5) is used depending on the size of the fetus.

From a therapeutic point of view, it is essential to confirm the presence of bacteriuria (a condition in which there are bacteria in the urine) since symptoms alone are not a reliable method of documenting infection. This applies particularly to bladder infection where the symptoms of burning micturition (dysuria) and frequency can be associated with a variety of non-bacteriuric conditions. Patients with symptomatic bacteriuria should always be treated. However, the necessity to treat asymptomatic bacteriuric patients varies with age and the presence or absence of underlying urinary tract abnormalities. In the pre-school child it is essential to treat all urinary tract infections and maintain the urine in a sterile state so that normal kidney maturation can proceed. Likewise in pregnancy there is a risk of infection ascending from the bladder to involve the kidney. This is a serious complication and may result in premature labour. Other indications for treating asymptomatic bacteriuria include the presence of underlying renal abnormalities such as stones which may be associated with repeated infections caused by Proteus spp. 

LC is a 28-year-old woman who comes to your practice because she thinks that she is pregnant. She reports that she has not had a period in 9 weeks. When she first missed her period just over 1 month ago, she was not concerned because her cycle had become very light. However, when she missed her cycle again, she took a home pregnancy test. That test was positive. In your practice, a repeat urine pregnancy test confirms that the patient is pregnant. 

There is no experimental evidence available to assess whether the toxicokinetics of -hexane differ between children and adults. Experiments in the rat model comparing kinetic parameters in weanling and mature animals after exposure to -hexane would be useful. These experiments should be designed to determine the concentration-time dependence (area under the curve) for blood levels of the neurotoxic /7-hcxane metabolite 2,5-hexanedione. w-Hcxanc and its metabolites cross the placenta in the rat (Bus et al. 1979) however, no preferential distribution to the fetus was observed. -Hexane has been detected, but not quantified, in human breast milk (Pellizzari et al. 1982), and a milk/blood partition coefficient of 2.10 has been determined experimentally in humans (Fisher et al. 1997). However, no pharmacokinetic experiments are available to confirm that -hexane or its metabolites are actually transferred to breast milk. Based on studies in humans, it appears unlikely that significant amounts of -hexane would be stored in human tissues at likely levels of exposure, so it is unlikely that maternal stores would be released upon pregnancy or lactation. A PBPK model is available for the transfer of M-hcxanc from milk to a nursing infant (Fisher et al. 1997) the model predicted that -hcxane intake by a nursing infant whose mother was exposed to 50 ppm at work would be well below the EPA advisory level for a 10-kg infant. However, this model cannot be validated without data on -hexane content in milk under known exposure conditions. 

Studies in animals confirm that endrin s main target is the nervous system, probably because the brain and other parts of the nervous system contain much fatty tissue, and endrin tends to stay in those tissues. Birth defects, especially abnormal bone formation, have been seen in some animal studies. While there are no human data on birth defects, evidence in rodents suggests that exposure to high doses of endrin during pregnancy could be a health risk to developing fetuses. 

If the woman has adhered to the prescribed regimen and misses 2 consecutive periods, rule out pregnancy. Discontinue use of the patch if pregnancy is confirmed. 

In the event of a missed menstrual period If the patient has not adhered to the prescribed regimen, consider the possibility of pregnancy at the time of the first missed period and discontinue the use of the contraceptive vaginal ring if pregnancy is confirmed. 

Pregnancy term/naf/on- Misoprostol has been used in combination with mifepristone for pregnancy termination. Patients taking mifepristone must take 400 meg misoprostol orally 2 days after taking mifepristone unless a complete abortion has already been confirmed before that time.
