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. |

| This study attempted to discover evidence of the relationship that may exist between the development of phlebitis |
| and pulmonary emboli with the taking of oral contraceptive agents. A detailed study was made of a patient who |
| experienced anaphylactic shock following the intravenous administration of iron. As anaphylaxis is known to be |
| accompanied by profound activation of thromboplastin and development of a widely disseminated hypercoagulable |
| state such a case seemed to be an opportunity to study these conditions. Since glass tubes were found not to be as |
| accurate in determining clotting time as plastic, plastic tubes and the Lee-White method were used. A shortening |
| of clotting time was demonstrated 15 minutes after the onset of the reaction. Clot lysis was greatly activated. Both |
| clotting time and clot lysis had returned to normal 45 minutes after the reaction began. Plasma recalcification time |
| and partial thromboplastin were also greatly reduced but returned to normal when the patient had recovered from the |
| anaphylactic shock. To study the effect of steroid hormones the following functions should be evaluated: 1) the |
| hemostatic capacity of blood vessels, 2) the number and function of blood platelets, 3) the function of each |
| compartment involved in blood coagulation at each stage, 4) the degree of activity of blood coagulation inhibitors, |
| and 5) the activity of clot lysins. The total appraisal must be made at frequent and short intervals in order to detect |
| the very evanescent alterations. Another patient who had a longer than normal clotting time before taking oral |
| contraceptives was found while under such treatment to have an alarming progressive shortening of the clotting time |
| and a similar trend in plasma recalcification time and in the partial thromboplastin time. Other laboratory tests of |
| hemostatic or blood coagulation mechanisms were normal. After stopping the contraceptives, tests returned to |
| normal. Afterward it was found that the patient was in a constant emotional state and especially when she came to |
| the laboratory. She was suffering from pyelonephritis of a year's duration and gave a history of jaundice 17 years |
| previously. A septic abortion with severe hemorrhage had recently taken place. Several blood transfusions had been |
| given with severe reaction after one of them. Prolonged clotting time, the presence of coagulating inhibitors and |
| active fibrinolysis were shown. Extensive dental caries and gingival infection were present. Hyperadrenalism at the |
| time of visiting the laboratory was believed to be present due to maritial troubles attending the visits. After this |
| patient started oral contraceptives again, clotting time decreased, blood viscosity increased, thrombophlebitis and |
| thromboses occurred at the sites of venipunctures. When the contraceptives were stopped coagulation returned to |
| the pretreatment state. It is believed continuation of oral contraceptives might have precipitated a clinical |
| catastrophy. More attention should be directed to those factors which may contribute to an untoward effect of an |
| otherwise safe agent such as the presence of infection and local or generalized vascular disease. Profound |
| emotional stress may cause bizarre biological changes including alteration in blood coagulation and especially |
| thrombotic states. Prompt conduct of the proper studies when thromboembolic complications occur with oral |
| contraceptives may throw more light on this subject. (PubHealth.info Document ID: CONT9T 1080-06) |
