- Pathophysiology. Rupture of the membranes is the most common cause of oligohydramnios. However, because the amniotic fluid is primarily fetal urine in the latter half of the pregnancy, the absence of fetal urine production or a blockage in the fetus' urinary tract can also result in oligohydramnios.

- It is not always possible to determine what causes low levels of amniotic fluid. Oligohydramnios can be caused by a continuous leaking of amniotic fluid. It can also occur when the fetus has kidney failure. After about four months of pregnancy, the kidneys of a normal fetus will produce the amniotic fluid. If the fetus has kidney abnormalities, the amount of amniotic fluid may be too low.

Noninfectious Meningitis Disorders that most commonly cause meningitis include disorders that cause inflammation, including the inflammation that occurs when the body's immune system malfunctions and attacks the body's own tissues (autoimmune disorders). Such disorders include rheumatoid arthritis and systemic lupus erythematosus (lupus).Drugs that can cause meningitis include nonsteroidal anti-inflammatory drugs (NSAIDs) and certain antibiotics. Noninfectious meningitis may also develop after fluid leaks from a brain cyst into the subarachnoid space.Such cysts may be caused by a tapeworm infection called cysticercosis (see Cysticercosis).his space contains the cerebrospinal fluid. Noninfectious meningitis is a type of aseptic meningitis (meningitis caused by something other than the bacteria that typically cause acute meningitis). Disorders and drugs are uncommon causes of meningitis.

What Is Anhydramnios? If the anhydramnios is the result of a tear in the lining of the placenta, there is a chance that the infant can survive past birth. The infant will require assistance with breathing for a time. In most cases, however, the complete lack of amniotic fluid will leave the infant’s lungs severely underdeveloped.

- Studies show an increased risk of associated fetal anomalies in more severe forms of polyhydramnios. In a series in 1990, 20% of cases of polyhydramnios involved associated fetal anomalies, including problems of the GI system (40%), CNS (26%), cardiovascular system (22%), or genitourinary system (13%).

Intrauterine Growth Restriction (IUGR) Causes of Intrauterine Growth Restriction. IUGR has many possible causes. A common cause is a problem with the placenta. The placenta is the tissue that joins the mother and fetus, carrying oxygen and nutrients to the baby and permitting the release of waste products from the baby.

Macrosomia and Birth Injury Macrosomia is more likely to be a result of maternal diabetes, obesity or weight gain than any other causes. In addition, maternal diabetes and macrosomia are the strongest risk factors for shoulder dystocia, and the highest risk of shoulder dystocia occurs when both these factors are present.

Amniotic Fluid Excessive amniotic fluid level in the uterus is known as polyhydramnios which can lead to symptoms like difficulty breathing, excessive weight gain and edema. Various factors may be responsible for elevated fluid levels, such as maternal diabetes and infectious conditions as well as fetal abnormalities.

Overview Hemolytic uremic syndrome (HUS) Overview. Hemolytic uremic syndrome (HUS) is a condition caused by the abnormal destruction of red blood cells. The damaged red blood cells clog the filtering system in the kidneys, which can lead to life-threatening kidney failure. HUS usually develops in children after five to 10 days of diarrhea — often bloody — caused by infection with certain strains of Escherichia coli (E. coli) bacteria. Adults also can develop HUS due to E. coli or other types of infection, certain medications, or pregnancy. HUS is a serious condition.

- Renal tubular dysgenesis is characterized by abnormal kidney development before birth, the inability to produce urine (anuria), and severe low blood pressure (hypotension). These problems result in a reduction of amniotic fluid (oligohydramnios), which leads to a set of birth defects known as the Potter sequence.

What Is Oligohydramnios? The amniotic fluid is like a life support system for the baby. During pregnancy, it nourishes, protects and cushions it. The presence of amniotic fluid ensures that the development and growth of the baby takes place in an adequate manner. The optimum volume of amniotic fluid varies from person to person however if the level is dangerously low (less than 4 cm), the condition is called Oligohydramnios.

Low Amniotic Fluid Levels: Oligohydramnios It is first made up of water that is provided by the mother, and then around 20 weeks fetal urine becomes the primary substance. As the baby grows he or she will move and tumble in the womb with the help of the amniotic fluid. In the second trimester the baby will begin to breathe and swallow the amniotic fluid. In some cases the amniotic fluid may measure too low or too high. If the measurement of amniotic fluid is too low it is called oligohydramnios. If the measurement of amniotic fluid is too high it is called polyhydramnios.

- “Burning an aromatherapy candle made of paraffin is similar to preparing a healthy drink of fresh squeezed juice and adding a shot of gasoline,” says Eric Johnson of Candleworks, an Iowa City, Iowa based company that specializes in wholesaling nontoxic aromatherapy candles.) For unburnt candles, rub the tip of the wick on a piece of paper. If it leaves a gray mark, like a pencil, the wick contains a lead core. If you’ve already purchased the candle, take it back to the store and tell the manager why you’re demanding a refund.

Macrosomia and Birth Injury Causes of Fetal Macrosomia. Fetal macrosomia usually develops when a baby receives too many nutrients. This can occur when the mother is obese or suffers from diabetes, particularly gestational diabetes. In some instances, a baby has a medical condition that speeds fetal growth.

Meningitis Meningitis is most often caused by a bacterial or viral infection. It also may be caused by a fungal infection, parasite, a reaction to certain medications or medical treatments, a rheumatologic disease such as lupus, some types of cancer, or a traumatic injury to the head or spine.acterial meningitis is a rare but potentially fatal disease. It can be caused by several types of bacteria that first cause an upper respiratory tract infection and then travel through the blood stream to the brain. The disease can also occur when certain bacteria invade the meninges directly.
