Hematologist

Hematologists are physicians who specialize in diagnosing and treating ailments related to blood, and blood systems such as bone marrow, vascular systems etc. They deal with conditions such as anemia, leukemia etc. Hematologists should be strong in the field of internal medicine, anatomy, physiology, and bio-chemistry too. A hematologist completes medical school and undergoes internship for three years in the field of internal medicine and further specializes for two years in the field of hematology. Few hematologists are also trained oncologists, who treat problems related to blood cancer. Hematologists are specialists in treating blood disorders and anything to do with blood. They

Tubal Pregnancy

Tubal pregnancy is also known as ectopic pregnancy - a condition where the fertilized egg implants itself in the fallopian tubes or any other tissue outside of the uterus. Tubal pregnancy can be life threatening, if not attended to in time. This is because it can lead to the rupture of the pelvic organ and consequent hemorrhage. It can also affect the woman's ability to become pregnant later. Since it is impossible to carry a tubal pregnancy to term, it becomes imperative to resort to surgery to remove the products of conception since they cannot develop into a fetus. This is done without damage to fallopian tubes, as far as possible. This can be done with laparoscopy in non-emergency situations. Tubal pregnancy can happen to any woman but there are some causes that can increase the likelihood of such a pregnancy condition. Some of the causes for tubal pregnancy are: Pelvic Inflammatory Disease, endometriosis or tubal scarring. Infection of the fallopian tubes such as gonorrhea or chlamydia can lead to a tubal pregnancy. The risk of ectopic pregnancy is manifold in cases of pregnancy after tubal sterilization. The use of the 'morning after pill' - emergency contraception is often noticed as a cause for tubal pregnancy.

An ectopic pregnancy is usually detected in the first 5 - 10 weeks of pregnancy. Ultrasound tests and hCG levels in the blood can help in identifying an ectopic pregnancy. The rate of increase of hCG in the blood is much slower in the case of an ectopic pregnancy or a potential miscarriage. Lower progesterone levels can also be an indication of likely tubal pregnancy. A woman having a tubal pregnancy will experience lower abdominal pain with cramping. There may be abnormal vaginal bleeding and breast tenderness. Lower back pain is another symptom. Severe bleeding and hemorrhage is the most dangerous symptom of ectopic pregnancy and needs prompt medical attention. If there is an emergency situation, there may be a need for blood transfusion.

Placenta Previa

Placenta Previa is a condition where the placenta embeds itself in such a way that it partially or completely covers the cervix. In such a case, the placenta lies low in the uterus and is at risk of separation from the uterine wall during labor contractions. When a pregnant woman experiences painles vaginal bleeding during the third trimester, the doctor may conduct an ultrasound to check for placenta previa. Other symptoms that might indicate placenta previa are a large uterine size, breech or transverse position of the baby or premature contractions.

usually placenta previa is detected during routine ultrasound scans of the growing fetus. Women who are over 35 years or have had multiple pregnancies are at higher risk of placenta previa. If a woman is diagnosed with placenta previa, she will need to take bed rest. Often hospitalization is necessary. Travel must be avoided and pelvic examination by the doctor is not advisable. Instead the doctor will resort to ultrasounds and MRI.

Placenta previa can cause growth retardation in the fetus due to irregularly placed placenta. This can lead to increased chances of congenital anomalies. The expectant mother is at risk for hemorrhage. Blood transfusion is resorted to in cases of severe bleeding.
