Childhood CT scans linked to leukemia and brain cancer later in life

Children and young adults scanned multiple times by computed tomography (CT), have a small increased risk of leukemia and brain tumors in the decade following their first scan. These findings are from a study of more than 175,000 children and young adults that was led by researchers at the National Cancer Institute (NCI), part of the National Institutes of Health, and at the Institute of Health and Society, Newcastle University, England. The researchers emphasize that when a child suffers a major head injury or develops a life–threatening illness, the benefits of clinically appropriate CT scans should outweigh future cancer risks. The results of the study were published online in The Lancet on June 7, 2012.

"This cohort study provides the first direct evidence of a link between exposure to radiation from CT and cancer risk in children," said senior investigator Amy Berrington de González, Ph.D., Division of Cancer Epidemiology and Genetics, NCI. "Ours is the first population–based study to capture data on every CT scan to an individual during childhood or young adulthood and then measure the subsequent cancer risk."

Despite the elevation in cancer risk, these two malignancies are relatively rare and the actual number of additional cases caused by radiation exposure from CT scans is small. The most recent (2009) U.S.

annual cancer incidence rates for children from birth through age 21 for leukemia and brain and other nervous system cancers are 4.3 per 100,000 and 2.9 per 100,000, respectively. The investigators estimate that for every 10,000 head CT scans performed on children 10 years of age or younger, one case of leukemia and one brain tumor would occur in the decade following the first CT beyond what would have been expected had no CT scans been performed.

CT scans deliver a dose of ionizing radiation to the body part being scanned and to nearby tissues. Even at relatively low doses, ionizing radiation can break the chemical bonds in DNA, causing damage to genes that may increase a person’s risk of developing cancer. Children typically face a higher risk of cancer from ionizing radiation exposure than do adults exposed to similar doses. The investigators obtained CT examination records from radiology departments in hospitals across Britain and linked them to data on cancer diagnoses and deaths. The study included people who underwent CT scans at British National Health Service hospitals from birth to 22 years of age between 1985 and 2002. Information on cancer incidence and mortality from 1985 through 2008 was obtained from the National Health Service Central Registry, a national database of cancer registrations, deaths and emigrations.

Approximately sixty percent of the CT scans were of the head, with similar proportions in males and females. The investigators estimated cumulative doses from the CT scans received by each patient, and assessed the subsequent cancer risk for an average of 10 years after the first CT. The researchers found a clear relationship between the increase in cancer risk and increasing cumulative dose of radiation. A three–fold increase in the risk of brain tumors appeared following a cumulative absorbed dose to the head of 50 to 60 milligray (abbreviated mGy, which is a unit of estimated absorbed dose of ionizing radiation). Similarly, a three–fold increase in the risk of leukemia appeared after the same dose to bone marrow (the part of the body responsible for generating blood cells). The comparison group consisted of individuals who had cumulative doses of less than 5 mGy to the relevant regions of the body.

The absorbed dose from a CT scan depends on factors including age at exposure, sex, examination type, and year of scan. Broadly speaking, two or three CT scans of the head using current scanner settings would be required to yield a dose of 50 to 60 mGy to the brain. The same dose to bone marrow would be produced by five to 10 head CT scans, using current scanner settings for children under age 15.

In countries like the United States and Britain, the use of CT scans in children and adults has increased rapidly since their introduction 30 years ago. Due to efforts by medical societies, government regulators, and CT manufacturers, scans performed on young children in 2012 can have 50 percent lower radiation doses, compared to scans carried out in the 1980s and 1990s, say the investigators. However, the amount of radiation delivered during a single CT scan can still vary greatly and is often up to 10 times higher than that delivered in a conventional X–ray procedure.

The lead author of the study was Mark S. Pearce, Ph.D., Institute of Health and Society, Newcastle University. "CT can be highly beneficial for early diagnosis, for clinical decision–making, and for saving lives. However, greater efforts should be made to ensure clinical justification and to keep doses as low as reasonably achievable," said Pearce. (Source NIH)

Mumbai’s population plunged 6% in last decade

MUMBAI: It may be hard to believe but Mumbai recorded its slowest population growth in almost a century in the last decade. The population of the island city shrunk by 5.75% from 2001 to 2011, recording the sharpest drop in south Mumbai since 1901, according to a detailed analysis of the latest Census data. Although the suburbs added 8.01% more people in the same 10–year–period, their growth was the slowest since the 1920s. On the occasion of World Population Day today, demographers believe the news augurs well for the city even as they differ on the reasons for the changing population dynamics. While some attribute the decline in population growth to people choosing smaller families, others point to the saturation of the financial capital, plagued as it is with disappearing job opportunities and shrinkage of affordable homes. The Census is yet to release migration–related data which might offer more insights. "This is historically the lowest population growth in the island city. In the suburbs too, the rapidly declining trend indicates that population growth there too would hit zero or touch negative in the next decade," says P Arokiasamy of the International Institute for Population Sciences, an autonomous institute under the Union ministry of health and family welfare. Demographers say Mumbai’s people shifts are in keeping with global trends where population expectedly peaks at the nascent stages of development and subsequently falls. The city’s population peaked till the fifties, with the suburbs seeing exponential growth between the 1950s and 1980s. However, the growth decline can’t undermine the challenges posed by the existing population. Five lakh more people were added in Mumbai in the past decade, taking its population to 1.24 crore, with an average of 20,038 persons packed into every square kilometre in the city and 20,925 persons in the extended suburbs.

Fake sweeteners might help keep pounds off

Can artificial sweeteners help people reach and maintain a healthy body weight? Maybe, according to two major medical societies. A scientific statement issued by the American Heart Association and the American Diabetes Association concluded that using non–nutritive sweeteners could cut down on added sugars and therefore lead to beneficial effects. But an extensive literature search found sketchy, limited, and often contradictory evidence, researchers concluded in Circulation: Journal of the American Heart Association and Diabetes Care.

Why do Kanwarias offer Ganges water in the month of Shravan?

There are some examples in mythology

  1. The custom of carrying Kanwar started in the Treta Yuga. Lord Rama had carried the holy Ganges water from Sultanganj in a kanwar and offered it to Lord Shiva at Babadham.
  2. When the churning of oceans – Samudra Manthan – took place in the month of Shravan, fourteen different types of rubies came out. Thirteen of these were distributed amongst the demons, except Halahal (poison). Lord Shiva drank the Halahal and stored it in his throat.

    Legal Question of the Day

(Dr MC Gupta)

Q. What are the latest amendments to the PC&PNDT Rules? What are your comments?

Ans.

  • Vide gazette notification dated 4–6–2012, the PNDT (Amendment) Rules, 2012, have been notified, the effect of which is as follows:
    • Sub–rule (3) has been added to Rule 3 as follows:

      (3) "Each medical practitioner qualified under the Act to conduct ultrasonography in a genetic clinic/ultrasound clinic/imaging centre shall be permitted to be registered with a maximum of two such clinics/centres within a district. The consulting hours for such medical practitioner shall be clearly specified by each clinic/centre,"
    • Application fee as per Rule 5(a) and 5(b) has been enhanced from Rs. 3000 and 4000 to Rs. 25000 and 35000 respectively.
  • The effect of sub–rule (3) above is as follows:
    • An ultrasonologist under the Act shall be permitted to be registered with a maximum of two such clinics/centres within a district.
    • The consulting hours for such medical practitioner shall be clearly specified by each clinic/centre.
  • The first question that arises is this—"Can an ultrasonologist register himself in more than one district"? This is particularly relevant to those living near district boundaries. For example, Delhi has nine districts. A doctor living in one district can reach any other district in 15 to 60 minutes.

    Will it be illegal for him to practice in a centre each in two different districts?
  • The legal answer to the above question is that this should be possible. There is nothing in the PC&PNDT Act or Rules that bars one from working in two districts.
  • The second question that arises is this—Is it legally correct that—"The consulting hours for such medical practitioner shall be clearly specified by each clinic/centre"?
  • The legal answer to the above question is that:
    • Let the centre try to get registered by submitting an application in terms of section 18(2) of the Act, specifying therein the consulting hours as follows: "The doctor will be on call duty and will be available as and when he is called".
    • If the registering authority refuses to accept this as a proper answer and rejects the application in terms of section 19(2), the applicant would be entitled to file a WP in the HC against such rejection.
    • The ground taken in the WP will be that the rule is violative of Article 19(1)(g) and places an unreasonable restriction on carrying out the profession, occupation, trade or business. My hunch is that if argued properly, the HC will decide in favour of the petitioner.
  • The third question that arises is this—"Can the increase in application fee be challenged?"
  • The answer to the above question is:
    • Yes, it can and should be challenged.
    • The first step—IMA or a radiologists’ association or a nursing home owners’ association should send a legally drafted representation to the ministry of Health, GOI, against such increase.
    • The second step—If the MOH does not take action, file a WP.
    • The grounds taken in the WP will be:
      • The increase in fee has to have a rational basis. There is no rational reason for the increase from 3000–4000 to 25000–35000.
      • The fee is non–refundable in terms of Rule 5(1). The government cannot be allowed to loot the public in this manner.
      • This will lead to an increase in charges to consumers and will thus be an anti–people act.

Teens on fast food get kidney stones

Mail Today, Nalini Ravichandran

New Delhi: If you thought kidney stones were a problem reserved for those in their 40s and above, here is some disturbing news: An increasing number of teens are being diagnosed by city doctors with the problem, taking parents and the medical community by surprise. According to Dr Anant Kumar, director, urology and kidney transplant, Fortis hospital, at least 15 youngsters come in with kidney stones every month — from 8 year olds to teenagers and those in their early 20s. There has been a 10 per cent rise in the numbers, and kidney stones are more common than gall bladder stones these days. Unlike stones in the gall bladder that are often a result of malnourishment, kidney stones are the product of an unhealthy lifestyle. "Kids these days love cheeseburgers and junk food — they favour processed foods with high amount of salt and preservatives and also frozen non–vegetarian food. Most of these youngsters are obese and this predisposes them to the condition," Dr Sanjiv Saxena, head and senior consultant, nephrology, PSRI hospital said. This apart, mindless consumption of high protein supplements coupled with an extremely low fluid intake can also be blamed. "Young people don’t drink enough water and juice and end up being dehydrated. Aerated drinks are preferred, which add to the damage. Smoking and a high alcohol intake can contribute to early stone formation," Dr Kumar said. Apart from the lifestyle related triggers, about 40 per cent of the kids are genetically prone to this medical condition.

Triglycerides

  • Markedly increased triglycerides (>500 mg/dL) usually indicate a nonfasting patient (i.e., one having consumed any calories within 12–14 hour period prior to specimen collection).
  • If patient is fasting, hypertriglyceridemia is seen in hyperlipoproteinemia types I, IIb, III, IV, and V. Exact classification theoretically requires lipoprotein electrophoresis, but this is not usually necessary to assess a patient’s risk to atherosclerosis.
  • Cholestyramine, corticosteroids, estrogens, ethanol, miconazole (intravenous), oral contraceptives, spironolactone, stress, and high carbohydrate intake are known to increase triglycerides.
  • Decreased serum triglycerides are seen in abetalipoproteinemia, chronic obstructive pulmonary disease, hyperthyroidism, malnutrition and malabsorption states.

Haemophilus Influenzae Type B Vaccine (Hib)

The bacteria Haemophilus influenzae type b (Hib), is one of the 6 types (a, b, c, d, e and f) of strains of the bacteria causing almost all systemic infections (95%).

H. influenzae is transmitted through the respiratory tract from infected patient to susceptible individuals. The infections caused include severe pneumonia, meningitis and other invasive diseases, almost exclusively in children aged less than 5 years. Even with proper treatment 3–25% of affected children may die. WHO reported (2000) that these bacteria caused 2 to 3 million cases of serious disease, notably pneumonia and meningitis, and 386 000 deaths in young children. Hib disease occurs in India but is difficult to confirm because it requires prompt laboratory investigation prior to administration of any antibiotic in patients. Since 1998, WHO has recommended that Hib vaccine be included in EPI in all countries. Following use of Hib vaccines into EPI, Hib disease has largely disappeared in Australia, Canada, New Zealand, USA and W/Europe. However, this vaccine is not part of EPI in India, so far.

The CDC and WHO currently recommend that all infants be vaccinated using a polysaccharide–protein conjugate Hib vaccine, starting after the age of 6 weeks. We should endeavor to immunize the infants with conjugate Hib vaccine, even though it is not part of EPI.

Travel more than doubles risk of blood clots

Long distance travelers periodically should move around and stretch their legs instead of just sitting and also drink plenty of water to stay hydrated, said Padma Shri and Dr B C Roy National Awardee Dr KK Aggarwal, President Heart Care Foundation of India.

Long–distance travel can lead to potentially fatal blood clots in some people and the risk grows with the length of the trip. Those at increased risk of blood clots include cancer patients, people who have recently had major surgery such as a joint replacement, and women on birth control pills.

In general, travel is associated with a nearly three-fold increase in the risk of venous thromboembolism (blood clots that form in the veins), often in the legs. If such a clot dislodges and travels to the lungs, it can cause a potentially fatal condition called pulmonary embolism.

A combination of factors including dehydration and hours of sitting in cramped conditions explains why some people develop blood clots.

A review, published in the Annals of Internal Medicine, analyzed 14 studies involving more than 4,000 cases of venous thromboembolism and found that travelers had a nearly three–fold higher risk of blood clots than non–travelers. The risk climbed along with the duration of the trip –– rising 18 percent for every two hours of any type of travel, and by 26 percent for every two hours of air travel.

But there is no reason for panic, because the absolute risk to any one traveler is still low. People who travel long distances should be aware of the risk of blood clots and learn to recognize the symptoms. Symptoms of a blood clot in the leg include pain, warmth, swelling and redness in the limb. If the clot travels to the lungs, it may cause sudden shortness of breath, chest pain or a cough that produces blood.
