    Studies Confirm HPV Shot Is Safe

    The HPV vaccine gives parents a chance to prevent their children from developing some types of cancer, and two new studies reaffirm what past research has found — the vaccine is safe.

    The two studies included millions of doses of Gardasil 9 vaccine, the only vaccine currently used in the United States for the prevention of HPV-related cancers.

    “The data from our study was very reassuring. We saw nothing unexpected or surprising. With Gardasil 9, we can now prevent a large portion of cervical, oropharyngeal [mouth, tongue and throat] and other cancers,” said one of the studies’ lead author, Dr. James Donahue. He’s an epidemiologist with the Marshfield Clinic Research Institute in Wisconsin.

    The studies and an accompanying editorial were published Nov. 18 in the journal Pediatrics.

    Human papillomavirus (HPV) is a sexually transmitted virus. It’s estimated that 79 million people in the United States are already infected with HPV. Around 14 million new infections with HPV occur every year. About half of those are teens and young adults, according to the editorial. Sometimes these infections get better on their own, but many do not.

    HPV is responsible for more than 33,000 cancers each year — 20,000 in women and 13,000 in men. Routine use of the Gardasil 9 vaccine could prevent about 90% of these cancers, the editorial said.

  • Cancer Risk May Rise After Heart Attack

    Cancer Risk May Rise After Heart Attack

    Here’s some worrisome news for folks who manage to survive a heart attack: New research suggests they might be far more vulnerable to developing cancer down the road.

    People who suffered a heart health scare — a heart attack, heart failure or a dangerously erratic heart rhythm — had a more than sevenfold increased risk for subsequently developing cancer, compared to those with healthy tickers, researchers said.

    “We found that folks with certain risk factors for heart disease had an increased risk of cancer and, more intriguingly, we found up that individuals who ended up developing heart disease had a significantly increased risk of future cancer,”

    lead researcher Dr. Emily Lau, a cardiology fellow at Massachusetts General Hospital in Boston.

    These findings are based on data from the Framingham Heart Study, a famous decades-long research project following the heart health of people living in the small town of Framingham, Mass.

    Lau and her colleagues had noticed that many regular patients with heart disease were also fighting cancer.

  • Tropical liver disease

    Tropical liver disease

    The liver is frequently involved in infections that are prevalent in different regions of the tropics, and chronic liver disease, sometimes with multiple aetiological explanations, is an important cause of early morbidity and mortality. This article describes some hepatic and biliary problems that are seen in the tropics or can be imported from resource-poor settings.

    The epidemiology of hepatitis A is changing in some areas, and hepatitis E is now recognized in an increasing range of tropical and non-tropical settings. Vaccines have been developed against hepatitis E. Hepatitis B and C continue to cause chronic liver disease, cirrhosis and hepatocellular carcinoma, but these can be eclipsed in epidemiological importance by the sequelae of the emerging epidemic of non-alcoholic fatty liver disease in many parts of the tropics.

    The pathophysiology of acute and chronic liver disease caused by aflatoxins is better understood, as is the relationship of veno-occlusive disease of the liver to pyrrolizidine alkaloids. Self-poisoning with hepatotoxins is common in many countries. The diagnosis and management of cystic hydatid disease of the liver has been rationalized, based on a systematic approach to the classification of imaging findings.
