Because a woman’s birth canal is curved and only a little wider than a fetus’s head, a baby must proceed through the canal in a specific sequence of moves. A failure during the process, such as a head turned the wrong way at the wrong time, can result in difficult labor or dystocia.

Using the new software, called PREDIBIRTH, Dr. Olivier Ami and a team of researchers from the Department of Radiology at Antoine Béclères Hospital, Université Paris Sud, France, processed MR images of 24 pregnant women. The result was a three-dimensional (3-D) reconstruction of both the fetus and pelvis along with 72 possible trajectories of the baby’s head through the birth canal. The program scored each mothers likelihood of a normal birth based on these simulations.

“The mechanics of the human birth canal make for a very complicated delivery process compared to other mammals,” said Dr. Ami in a news release. “We now have computer-simulated childbirth to identify potential problems. The software simulates the properties of potential deliveries.”

For this study, the PREDIBIRTH scores were computed retrospectively and measured against delivery outcomes for the 24 women. Thirteen women had normal deliveries, which had been  scored as highly favorable by the simulator. Three women who had elective cesarean-section (C-section) were scored at high risk for dystocia.

Of the five women who had emergency C-sections, two involved heart rhythm abnormalities and had simulator scores of mildly favorable and favorable. Three involved obstructed labor, all of whom scored at high risk of dystocia. Three women delivered with vacuum extraction and had mildly favorable simulator scores.

Researchers say the results in predicting dystocia were highly accurate and are a notable improvement over pelvimetry, which measures the pelvis manually or by imaging to determine its adequacy for childbirth. While pelvimetry is commonly used, Dr. Ami said it’s not entirely reliable.

“A small pelvis may be able to deliver without problems, and a big pelvis might require mechanical help during childbirth,” he said. “This uncertainty raises the rate of C-sections.”

In the U.S., C-sections account for approximately one-third of all births. In France, the rate of mechanical problems is 30 percent, two-thirds of which are emergency procedures.

“An emergency C-section has six to seven times more morbidity and mortality than a planned C-section,” Dr. Ami said. “With this virtual childbirth software, the majority of C-sections could be planned rather than emergency, and difficult instrumental extractions might disappear in the near future.”

The study, involving 257 students, highlights that a higher degree of pain was experienced with the use of gaming devices compared to mobile phones. Pain reported by children using Xbox and Gameboy was statistically higher than pain reported for the iPhone.

Importantly, the length of time spent on the devices heightened the pain suffered, as the data demonstrated that length of time was independently associated with the pain reported, with the odds of reporting pain increasing by two for every one hour of play.

“Our study has shown the negative impact that playing computer games and using mobile phones can have on the joints of young children, raising concerns about the health impact of modern technology later in life,” said Professor Yusuf Yazici, Rheumatology, NYU Hospital for Joint Diseases, New York. “We hope that further research in this area will shed light on what could be a serious health concern for today’s gaming children, in later life.”

The study also investigated pain attributed to mobile phone usage for the sending of text messages, the number of texts sent, the use of abbreviations, and the type of keyboard used, according to age and gender.

The results indicated that female students reported twice as much pain as male students respectively, measured using the 10cm Visual Analogue Scale (VAS, a pain measurement scale) and gender was the only independent variable associated with pain.

The study involved 257, nine to 15 year old students from two schools in St Louis. They were administered with a questionnaire to aid researchers in determining the possible association device type, age of children and hours played may have on wrist and finger pain.

A multivariable generalised linear model examined whether reported pain was associated with game device usage adjusting for age, gender, school and duration of game play per game device.

The study results were presented last week during the European League Against Rheumatism 2011 Annual Congress.

The study is consistent with what doctors have long suspected, and why women of childbearing age are always asked about the possibility of pregnancy before being x- rayed.

A UK-US collaborative study found small increases in risk of cancer for children who had x-rays at ages less than three months and in children whose mothers had undergone an x-ray while pregnant. These increases were not statistically significant. The researchers report no increased risk from ultrasound scans.

Researchers studied the childhood cancer risk associated with exposure to radiation and ultrasound scans during gestation and in early infancy.

Previous studies of children born between the 1940s and the 1970s, when radiation doses were likely to be higher, found in utero x-ray exposure to be associated with an increased risk of childhood cancer, particularly leukemia. The effect of medical radiation on young children has been less clear.

Although diagnostic x-rays and other radiological imaging procedures to the abdomen and pelvis of pregnant women are rare, there are concerns about the growing use of computed tomography (CT) scans and other types of higher-dose imaging procedures on younger children.

Researchers compiled data on 2,690 children with cancer and 4,858 healthy children from the UK Childhood Cancer Study (UKCCS). All children were born between 1976 and 1996. Data on exposure to radiographic and ultrasound examinations were collected from medical records.

A total of 305 children received 319 radiographic and related examinations while in utero and 170 children received 247 diagnostic x-ray examinations in early infancy. A total of 13,723 in utero and 138 early infant ultrasound scans were carried out.

Researchers measured the risk of childhood cancer overall, and leukemia, lymphoma, and central nervous system tumors specifically.  Results showed a heightened risk following in utero exposure to x-rays for all cancers and for leukemia, though neither was statistically significant.

Exposure to diagnostic x-rays in early infancy was found to be associated with a small, non-significant extra risk for all cancers and leukemia, as well as increased risk of lymphoma, but this finding was based on small numbers (only seven cases).

The researchers conclude: “Our results, which indicate possible risks of cancer from radiation at doses lower than those associated with CT scans, suggest a need for cautious use of diagnostic radiation imaging procedures to the abdomen/pelvis of the mother during pregnancy and in children at very young ages.”

Babbling usually begins much earlier than at 12 months and is now thought to be necessary step towards learning to speak. In fact scientists have noted that babies babble in similar ways regardless of where they are born and what language they are learning. Babies begin transforming babble into the distinct sounds of their native tongue later as 2-year-olds.

By 6 or 7 months, babies’ babbling should include both consonants and vowels. If a baby makes only ooo or aaa sounds are not practicing their word formation and are not developing speech as quickly as most. At the latest, this should occur by 12 months.

Interestingly, babies must learn language from people; television and even educational videos do not work. Not only is human interaction crucial, but the type of interaction turns out to be important as well.

The moment a baby is babbling is an important teaching moment. Scientists think that while babies babble their brains are in a focused state of attention and they are primed to learn names of new objects.

A recent study found that showing a baby an object and naming it in response to the baby’s babble allowed the baby to learn the names better. So instead of just repeating the babbling or trying to guess, “Oh do you want your toy?,” we should either show them an object and name it or name the object they’re looking at.

Shoulder dystocia describes a birth in which the baby’s shoulder gets stuck behind the mother’s pubic bone, thus preventing the baby’s delivery. If the shoulder is not freed in a timely manner or is freed in a negligently manner, serious injury and death will occur. In fact, 20 percent of births involving shoulder dystocia result in the baby suffering serious injury. Examples include birth asphyxia, fractures of the humerus or collarbone, cuts, bruises or damage to the brachial plexus nerves, which can lead to paralysis of the arm and hand.

However, if a baby is determined to be at high risk for shoulder dystocia, preemptive c-sections can be performed to avoid the dangers associated with delivering a baby with shoulder dystocia. CALM is the tool of choice to predict this dangerous condition and give expecting parents some peace of mind about at least one aspect of birth. In making its prediction, the program weighs such factors as maternal history including previous shoulder dystocia and gestational diabetes, gestational age, estimated fetal weight, maternal weight and maternal height.

Though not perfect, CALM is the best tool we have to predict shoulder dystocia and can provide a measure of ease to expecting parents.
