PubHealth.info® (a subsidiary of PakMed) presents scientific information mainly based on abstracts of articles published on a variety of public health issues/topics, particularly encompassing population planning, disease prevention, maternal and child health, and communicable and non-communicable diseases (like HIV AIDS, malaria, etc) that are affecting a significant portion of population in developing and developed countries. Here you can find abstracts of articles published on a variety of public health topics under category "Contraception (Birth Control) and Family Planning". Contraception (birth control) is a regimen of one or more actions, devices, or medications followed in order to deliberately prevent or reduce the likelihood of a woman becoming pregnant or giving birth. Therefore contraception is the utilization of various and sundry surgical procedures, devices, practices, agents, or drugs with the intention of preventing conception or impregnation (pregnancy). Methods and intentions typically termed birth control may be considered a pivotal ingredient to family planning. Birth control is a controversial political and ethical issue in many cultures and religions, and although it is generally less controversial than abortion specifically.

ABSTRACT

30 controls (healthy euthyroid volunteers), 31 pregnant patients (17-41 years; 12-40 weeks gestation) and 20 patients

receiving oral contraceptives (OC) were tested to examine thyroid function. Serum was analyzed for total serum

thyroxine, T3-resin uptake, throxine binding globulin (TBG) and thyroxine-binding prealbumin (TBPA) capacities by

reverse flow paper electophoresis, and free thyroxine by equilibrium dialysis using a modification of the method of

Ingbar et al. 24 hour thyroid uptake was measured in some controls and in OC patients. "Free thyroxine index" was

calculated. The following results were obtained: 73% pregnant women and 35% OC patients had higher total serum

thyroxine than controls (p<.01); the T3-resin uptake was lower in pregnant women (65%) and OC patients than

controls (p<.01); 93% of pregnant women and 100% OC patients had higher TBG capacity than controls (p<.01);

mean value of absolute free thyroxine in pregnant women was significantly higher than controls (p<.01) and OC

patients (p<.05) confirming the euthyroid clinical status of OC patients although there were overlapping individual

values. The "free thyroxine index" was not reliable for testing small increases, the 24-hour uptake of iodine-131 was

normal in OC patients. (PubHealth.info Document ID: CONT9T 1005-06)
