Postpartum Hemorrhage Postpartum hemorrhage is blood loss of > 500 mL during or immediately after the 3rd stage of labor in a vaginal delivery or > 1000 mL in a cesarean delivery. Diagnosis is clinical. Treatment depends on etiology of the hemorrhage. Causes of postpartum hemorrhage : > Uterine atony (the most common) > Lacerations of the genital tract > Extension of an episiotomy > Uterine rupture > Bleeding disorders > Retained placental tissues > Hematoma > Uterine inversion >Subinvolution (incomplete involution) of the placental site (which usually occurs early but may occur as late as 1 mo after delivery) Risk factors for uterine atony include uterine overdistention (caused by multifetal pregnancy, polyhydramnios, or an abnormally large fetus), prolonged or dysfunctional labor, grand multiparity (delivery of ≥ 5 viable fetuses), relaxant anesthetics, rapid labor, and chorioamnionitis. Uterine fibroids may contribute to postpartum hemorrhage. A hi...

Oral cotraceptive pills are tablets that prevents conception. Perhaps its the most accepted contraceptive method in developing countries. Its principle function is to prevent conception and it doesn't give any protection against HIV and other STD's. Oral Contraceptive Pills (OCP) are mainly two types. 1. Combiled OCP. 2. Progesteron OR Estrogen only Pills. The mechanism of action of OCP is very simple. We know that female Menstrual cycle is devided into three phases. 1. Proliferative phase : Here estrogen is secreted by Ovary , which causes uterine endrometrial growth. After this phase there is sudden withdrwal af estrogen which causes Ovulation ( It is the fall of mature ovum into Peritoneal Cavity , which ultimately comes into the uterine tube and finally in uterus ). 2. Secretory phase : Here both Progesterone and Estrogen Causes more and more growth if endometrium and increase secretion by the uterine glands. 3. The Menstrual phase : Here sudden Withdrawal of Progesterone ...

UNDERSTANDING CORONARY HEART DISEASE (CHD) According to current estimates, 64.4 million Americans have one or more types of cardiovascular disease. Within cardiovascular diseases, coronary heart disease (CHD) is the single largest killer of Americans. CHD caused 502,189 deaths in the US in 2001 – about 1 in every 5. The American Heart Association estimates that 13.2 million Americans have CHD. In fact, up to half of all sudden, out-of-hospital cardiac deaths occur in people with no prior diagnosis of heart disease, and over two-thirds of heart attach sufferers have blockages in their arteries considered to be clinically “insignificant” in terms of plaque burden and percent stenosis. Until recently, it was widely held that most heart attacks were caused by a gradual build-up of atherosclerotic plaque within the arteries of the heart (“hardening of the arteries”), impedes blood flow, and eventually results in blocked blood vessels that can cause acute ischemic events such as...

Research 06 : Diabetes Can Be Cured Parmanantly. Diabetes Mellitus ..... Its a very common name for some peoples of this world. Because its on the diseases that is also called a " silent killer ". But proper care can relives its symptoms. Let us Know what is Diabetes Mellitus (DM). Simply its a disease of Pancreatic B- Cells where there is less production of Insulin. As a result , blood glucose is not properly metabolised. So, there is extra amount of blood glucose which causes several symptoms.  Now , DM is a great challenge to treat. Now a days one in every 300 aged person has Insulin Dependant Type-I Diabetes (IDDM-I) . So redical cure of it can save thousands of People. Still today the only prophylaxis that causes symptomatic releive is Controlling DM. But, Researchers have reached beyond the limit. Experiment of Animals like Rat , shows that a B-Celll transplantation can prodeces sufficient amount of Insulin . And its sufficient to meet the peripheral demand of Insulin i...

Cancer which is also known as Carcinoma . There are two terms regarding cancer and these are benign and malignant. Benign cancers are not fatal and these can be cured by treatment like surgery and radiotherapy. But malignant cancers are fatal. Because it can not be cured by treatment due to its spreading nature. At first there are some stimuli that alters the normal function and growing pattern of a cell. The stimuli are called Carcinogens . Carcinogens are chemical or radiation or something like this. When carcinogens enter into the body repeatedly then it alters the normality of our cells. Then our cells show abnormality in growing and metabolism. At the same time our body tries to compensate this changes. But when fails then this abnormality takes figure into any benign lesion. This benign lesion can be the benign cancer cells in an adenoma ( Its a benign tumor of glandular tissue, like breast ) . Then these benign cells grows more rapidly due to repeated stimuli and finally spread...

A new Era is coming forward in the treatment of human body. That is the STEM CELL THERAPY. If this treatment comes forward then medical science can treat many of those major diseases that are killing a large number of people each year. There are many diseases now that can't be cured by medical treatment, like Paralysis . If a patient has paralysis then doctors give him only some supportive treatment to improve his nerve supply on that affected area. But it can't give a redical cure. Because if a nerve cell damaged it cant be regenerated due to it is mane if stable cells. But, if a stem cell is replaced on that area then it can regenerate a nerve cell because stem cell can grow in the form of any cells or tissues, it has that capacity. Although a stem cell can grow in any form of a tissue or an organ. So, if we can place a stem cell in that affected hand or leg then this stem cell will grow under control and can regenerate into that original tissue. So, the patient will be cu...

Dear Readers, do you know about risk factors of Lung cancer ? If you are residing in a city where polution is a great problem, like air pollution, then you be attacked by lung cancer. Also if you are a regular smoker then you are in great risk. Researches shows that only inhaling toxic smokes are not important. If you are containing " Genes " that causes lung cancer then you are in great risks. So, it is proved clinicaly that if you dont have a lung cancer gene then you may not attacked by lung cancer though you are a smoker or anything like this. But, the problem is we dont know that whether we have the gene responsible for lung cancer or not. So, it will better to quit smoking if you are a smoker. Also, clinicaly doctors get those poatients who have alredy developed a cancer after exposing to the risk factors for several years. So, if a person quits smoking even after 15years he will get rid from lung cancer. But, he must in a great risk.
