Pregnancy Safety Precautions
NEW YORK, May 3, 2003
(CBS) Alisa Kotler-Berkowitz and her son Matan are the picture of health today, but two-thirds of the way through her pregnancy, Kotler-Berkowitz got an unexpected diagnosis. She learned she had gestational diabetes. "I was concerned because I wasn't sure what it meant, I didn't know a lot about diabetes," says Kotler-Berkowitz.
A woman with gestational diabetes produces the right amount of insulin, but the insulin's effects are blocked by hormones made in her placenta. It's a condition that affects between 3 and 6 percent of non-diabetic women. Risk factors include a family history of diabetes, high blood pressure, obesity and being over the age of 30.
"It is very important that we screen pregnant women because there are no symptoms," says Mt. Sinai Hospital's Dr. Michelle Morgan. Women are tested for gestational diabetes between the 24th and 28th week of pregnancy. They begin by drinking a sugary solution. After one hour, their blood is drawn to check the glucose level. If it's too high, the expecting mom will have to undergo further testing. If it is determined a pregnant woman does have gestational diabetes, she must get it under control immediately. Failure to treat the condition can lead to serious problems for the baby, including excessive birth weight, low blood sugar, jaundice, respiratory problems and sometimes death.
In most cases, gestational diabetes is fairly easy to deal with.
"The main stays of treatment generally consist of a program of diet and exercise, and in some cases if the diabetes is not controlled, an addition insulin would be used," says Morgan.
Kotler-Berkowitz keeps her diabetes in check by following a healthy diet she hopes to maintain. "Lately I've rediscovered my love for chocolate so I'm sort of thinking about it, remembering my diabetic diet."
Dr. Mallika Marshall from WBZ-TV explained on The Saturday Early Show that regular exercise and a healthy diet have been shown to lower the chances of diabetes in people who are at risk. There's also a medication, called Metformin, that can help prevent diabetes in people who have mildly elevated blood sugar levels high enough for a diagnosis of diabetes.
Another problem some pregnant women may be concerned about is preeclampsia, says Marshall. It is commonly known as toxemia, or pregnancy-induced hypertension. It only occurs during pregnancy and affects about 5 percent of pregnant women in the United States. It usually develops in the second or third trimester.
Women with preeclampsia develop high blood pressure, protein in the urine and swelling of the legs, hands and sometimes the entire body. In rare cases, women can develop seizures and can even die from the condition.
The cause of preeclampsia is unknown, but it results in constriction of the blood vessels in the mother, which can decrease blood flow to placenta and to the fetus. This can slow the baby's growth.
Marshall says some women may develop swelling, headaches, blurry vision or abdominal pain if they have preeclampsia. But many women don't develop symptoms at all. That's why it's so important that pregnant women get regular prenatal care and have their blood pressure checked throughout their pregnancy.
The only cure for preeclampsia is to deliver the baby, because it resolves itself as soon as the pregnancy is over. If the symptoms are mild and it's too soon to deliver the baby safely, the woman will usually be put on bed rest and will be monitored closely by doctors and nurses. Sometimes women are hospitalized and treated with intravenous medications. But if symptoms are severe or the woman develops seizures, the baby has to be delivered.
Another problem to be on the lookout for in the later stages on pregnancy is bleeding. Some women may suffer from placenta previa, which happens when the placenta is located in an abnormally low position in the uterus, partially or completely blocking the cervix. In some cases, as the pregnancy progresses, the placenta changes locations and no longer obstructs the cervix. In some cases, a C-section is required for delivery.
In placental abruption another pregnancy-related problem, a part of the placenta detaches from the wall of the uterus, and can cause pain and bleeding. If minor, bed rest may be all that's required. If severe, the baby may have to be delivered by C-section.
Marshall says pregnant women with asthma are also at high risk of endangering their unborn child. About a third of women with asthma will notice their asthma symptoms worsen during pregnancy. However about a third of women get better during their pregnancy. Severe uncontrolled asthma can reduce the supply of oxygen to the baby and can increase the risk of premature birth.

SARS: Relapses, mutations puzzling
Saturday, May 3, 2003 Posted: 4:41 AM EDT (0841 GMT)
HONG KONG, China (CNN) -- Mutations of the SARS virus and relapses among patients are puzzling scientists trying to understand the disease, amid a five-fold increase in the number of deaths in the past month.
Doctors at the Chinese University of Hong Kong said there were two forms of SARS present in the hard-hit Chinese territory, which could complicate efforts to develop a diagnosis and vaccine.
"This rapid evolution is like that of a murderer who is trying to change his fingertips or even his appearance to try and escape detection," Dr Dennis Lo said. Lo added that more research needed to be done to determine if the virus had become more infectious or deadly.
There were ten new cases and nine deaths reported in Hong Kong on Saturday, bringing to 1621 the total number of infections recorded in the former British colony. A total of 179 people have died from SARS there, while almost 900 have been discharged. Also worrying scientists is at least a dozen cases of SARS relapses among discharged patients. The World Health Organization is set to discuss the issue with Hong Kong authorities on Monday. The territory's health chief has also admitted Hong Kong did not respond quickly enough to the SARS outbreak. This was because little was known about the disease, Health Secretary Dr. Yeoh Eng-kiong said in a radio interview on Saturday. Hong Kong authorities have been criticized for being tardy in imposing quarantines on people who might have been exposed to the virus.
However, recent figures in Hong Kong have backed a declaration from the WHO the SARS outbreak had peaked there. Across the border in mainland China, SARS cases continued to mount.
There were another 181 new cases and 9 more deaths in China on Saturday. Most cases and deaths have been reported in the capital, Beijing. So far around 1,600 people have been infected with SARS and 96 have died from it in China's hardest-hit mainland city to date. The deputy director of Beijing Health Bureau, Liang Wannian, said on Friday he believed the SARS epidemic "was in a stable period with the upward trend contained [in the capital]," China's official Xinhua news agency reported. Beijing authorities are hoping isolation may help. They have opened a new 1,000-bed hospital to handle patients with the virus and barricaded some roads as patients were being transferred.
The Xiaotangshan Hospital threw open its doors after more than 7,000 builders worked feverishly to erect the structure in just eight days.
China's central government has also reversed its stance and agreed to allow WHO send experts to Taiwan to assess the SARS outbreak there. China, which regards Taiwan as a renegade province, has blocked efforts by the island to join the United Nations body as an independent country. Taiwan has complained that its non-membership to the U.N. is behind a lack of response from the WHO to its requests for help against SARS. Taiwan authorities have reported nearly 100 SARS cases. There were five new fatalities Friday.
Globally more than 400 have died, and more than 6,000 have been infected with SARS.

In other developments:
• Toronto officials insist the disease is under control in the city after no new SARS cases were reported on Friday. The Canadian city has had the largest outbreak of the virus outside of Asia with 140 probable cases and 23 SARS deaths.
• Singaporean authorities have arrested a man who repeatedly flouted home quarantine. The man, who skipped quarantine and went out drinking on two occasions, was jailed in isolation on Friday. Singapore has put in place strict control measures and has recorded 25 deaths out of 203 cases.
• The World Health Organization says laboratory tests for SARS being used in India are inaccurate. So far, India has reported 19 cases of the disease and has quarantined 200 people.

Double Duty: Study Finds Viagra Works for Women
April 28 — A new study has found that the impotence drug Viagra could ramp up the sex lives of women who take it, just as it has done for men.
The 12-week study focused on 202 post-menopausal or post-hysterectomy women who complained of female sexual arousal disorder. The women in the group who took Sildenafil — the little blue pill commonly known as Viagra — took notes after each sexual experience, and reported better overall sexual satisfaction compared with those who took a placebo. Their enhanced sex lives included better arousal, lubrication and orgasm.
The study was conducted by Laura Berman, director of the Berman Center and a professor of OB-GYN and psychiatry at Northwestern University in Chicago, and Dr. Jennifer Berman, director of the Female Sexual Medicine Center at UCLA Medical Center in Los Angeles. The researchers say that the results are preliminary.
"In terms of ability to achieve orgasm, there was a statistically significant movement," Laura Berman said on ABCNEWS' Good Morning America.
"It increases blood flow to the genital area, increases the sensation of warmth, tingling and fullness," she said.
More than 50 million women experience some type of sexual dysfunction. Jennifer Berman said it's important for women to remember that this pill can't overcome mental and emotional barriers to a satisfying sex life.
"At this point, we can say that women with significant emotional or relationship problems and women that have desire problems related to their interest in being sexual might not be the best candidates," Jennifer Berman said. "It's for women who were satisfied with their sexual response at one point and now, for whatever medical reason, are no longer able to respond," she said.

Increased Blood Flow Theory
Women who suffer from female sexual arousal disorder can experience a variety of symptoms, including lack of "excitement," vaginal dryness, loss of sensation and sensitivity in the genitals and nipples and low blood flow to the genitals. Women in the study were screened to make sure that psychological or relationship issues were not the cause of the problem.
Since Viagra enhances sexual arousal in men by increasing the blood flow to the penis, the Bermans theorized that the drug could have a similar effect on women, increasing the blood flow to the female genitals and thereby producing better arousal, sensation and lubrication in the genital area.
Women in the study were given doses of 50 milligrams, which was increased to 100 milligrams only once during the study based on how well the lower dose was working, and the women's tolerance to it. The pill was to be taken prior to sexual activity but no more than once daily.
Each patient had to engage in sexual activity at least once a week and keep a personal log about it. During the course of the study, neither the patients nor the doctors knew which patients were receiving the Viagra. Women taking Viagra reported mild to moderate side effects, including headache, flushing, nausea, and vision symptoms — the same side effects reported by men who take the drug.

Bali suspect faces possible death
Wednesday, April 30, 2003 Posted: 12:28 AM EDT (0428 GMT)
BALI, Indonesia (AP) -- Indonesian prosecutors formally charged their first suspect Wednesday in last year's terror bombings on the resort island of Bali, which killed 202 people, mostly foreign tourists. The suspect, known by the single name Amrozi, allegedly belongs to Jemaah Islamiyah, the al Qaeda linked regional terror group blamed for the near-simultaneous bombings at two Bali nightclubs.
One of 29 people detained in connection with the October 12 attack, Amrozi faces charges of violating anti-terrorism laws that could carry the death penalty, a spokesman for the prosecution said.
His trial was expected to begin before May 12. No more details of the charges were immediately available.
Amrozi's arrest in November last year was considered the first major break in the investigation into the bombings.
Police claim he bought the explosives used in the attack and drove the van that blew up outside one of the clubs.
The blasts were the bloodiest terror assault since the September 11 attacks in the United States.
Jemaah Islamiyah also is thought to be behind a series of Christmas Eve church bombings in Indonesia in 2000, as well as a foiled plot to blow up U.S., Australian, British and Israeli missions in Singapore.
The group's alleged leader, Abu Bakar Ba'asyir, is currently on trial in Jakarta charged with treason in connection with the church attacks. He has not been charged in the Bali bombing.
Dozens of its alleged members have been arrested in Singapore and Malaysia. The group's goal, according to regional law enforcement officials, is to establish a pan-Islamic state in Southeast Asia.
Other suspects arrested over the Bali blasts are expected to go on trial later this year. All the trials are scheduled to take place on Bali island.
