Pfizer sued for paying kickbacks to doctors
A Texas health insurance company is suing Pfizer Inc. saying the drug maker deceptively marketed three of its top-selling drugs, illegally encouraging doctors to prescribe them for non-approved uses and paying kickbacks to doctors.

Health Care Service Corp., which runs Blue Cross Blue Shield of Texas and covers 12.4 million people in four states, filed the lawsuit against Pfizer on June 4.

Pfizer has settled other similar lawsuits and agreed in September to pay $2.3 billion in civil and criminal penalties over its promotion of Bextra, Lyrica, Geodon and other drugs. MORE HERE

Menstrual cycle and oral malodor connection
J of Perio Res June 2010
Sex hormones have been suggested to be important modifying factors that may influence the pathogenesis of periodontal disease. This study examined changes in volatile sulfur compounds (VSC) levels, clinical parameters and bacterial levels during the menstrual cycle.
Results: Bleeding on probing (BOP) was significantly increased in the ovulation phase in periodontitis subjects but not in healthy subjects. The VSC levels in subjects with periodontitis increased 2.2-fold in the ovulation phase compared with the follicular phase. In the ovulation phase, VSC levels and BOP were significantly higher in subjects with periodontitis than in healthy subjects. The number, and salivary levels, of Prevotella intermedia in subjects with periodontitis were significantly higher in the ovulation phase than in the follicular phase.
Conclusion: The present study indicated changes in VSC, BOP and P. intermedia during the menstrual cycles of women with periodontitis.

Periodontal connection in Elderly Men With and Without Osteoporosis or Osteopenia ..Journal of Periodontology- June 2010.
The osteoporosis subjects exhibited a significantly higher percentage of sites with clinical attachment loss (CAL) ≥6 mm, compared to osteopenia subjects (P <0.05); the former also showed a greater percentage of sites with interproximal gingival recession (GR) ≥5 mm than the controls (P <0.05) after excluding the smokers. The osteoporosis subjects were more likely (OR = 3.3, P <0.05) to exhibit interproximal GR ≥5 mm than the controls. Osteoporosis remained significantly associated with severe CAL and interproximal GR after adjusting for age, supragingival plaque and number of teeth lost.
Conclusion: This study suggests that osteoporosis is associated with severe clinical attachment loss and interproximal gingival recession in elderly Chinese men.

Comparison of Nimesulide versus meloxicam following extraction of impacted lower third molar Int J of Oral and Maxillofacial Surgery June 2010
This study compared the efficacy of nimesulide and meloxicam in the control of pain, swelling and trismus, following the extraction of impacted inferior third molars(wisdom tooth). Twenty patients with two impacted inferior third molars, in similar positions, were selected. The patients were designated randomly to the meloxicam group (MEL: 7.5 mg twice a day for 5 days) or the nimesulide group (NIM: 100 mg for 5 days). Following the extractions, swelling was more pronounced in the MEL group than in the NIM group (P ≤ 0.001). There were no significant differences in pain intensity between the treatment groups (P > 0.05). At the 72-h evaluation, reduction was significantly larger in mouth opening in the MEL group compared with the NIM group (P < 0.05). In conclusion, pain control was similar in both treatment groups. NIM was more effective than MEL in the control of swelling and trismus following the extraction of impacted lower third molars. MORE HERE

Dental Caries Treatment- Latest innovations
So far the hype was minimal invasive dentistry, Now it is Resin infiltration technique, read on ….

You know how to handle a frank cavity and what to do with a healthy tooth. But what about the many lesions that fall in between? A brace of new studies on resin infiltration suggests it can successfully treat lesions that are too small to restore but too big to ignore (no cavitation).
Currently, only one resin infiltration product is on the market: Icon (DMG America). To use it, practitioners first open the pores of the lesion with hydrochloric acid. The low viscosity of the resins allows it to penetrate these pores by capillary action. Once hardened, the resin then protects lesions from both acid and nutrients that feed bacteria. MORE HERE

TOOTHPASTE World Collection

US dentist Dr Val Kolpakov has a vast haul of 1,800 toothpastes ranging from whiskey-flavoured, to curry and bamboo. One dates to World War II and is made with a radioactive compound.

And he is hoping world record officials will recognise his as the world’s largest toothpaste collection.

He says: ‘I’ve submitted my application, and since there is no record for a number of toothpaste tubes, they had to review whether they can open a new category. Finally it was approved, and now I need to submit evidence that I have all these toothpastes.’ MORE HERE

Mothers’ Caries Increases Odds of Children’s Caries
JDR May 2010
This population-based study was conducted in a rural, primarily Hispanic, California community. Interview and dental examination data for mother-child (children < 18 yrs old) dyads were analyzed. In a Generalized Estimation Equation (GEE) logit model for mothers (n = 179) and children (n = 387), maternal untreated caries was a statistically significant correlate of child’s untreated caries, odds ratio (OR) = 1.76 (95%CI: 1.10, 2.70), adjusted for demographic factors. This relationship did not change when behavioral and dental utilization factors were added to the model, OR = 1.85 (95% CI: 1.12, 3.07).
Maternal untreated caries almost doubled the odds of children’s untreated caries and significantly increased child’s caries severity by about 3 surfaces. Caries prevention and dental utilization programs for mothers and their children should be increased.

That Smokeless Tobacco Damages DNA

Far from having adverse effects limited to the mouth, smokeless tobacco affects the normal function of a key family of enzymes found in almost every organ in the body, according to the first report on the topic in the American Chemical Society’s monthly journal Chemical Research in Toxicology.
Krishan Khanduja and colleagues note widespread recognition of smokeless tobacco’s harmful effects on the mouth, which include an increased risk of gum disease and oral cancer. The potential carcinogens and other chemicals in chewing tobacco and other smokeless products are absorbed into the blood and travel throughout the body. However, scientists have little information on smokeless tobacco’s effects on other parts of the body. MORE HERE

Coffee cuts mouth cancer risk, new study suggests
Researchers found regular coffee drinkers were 39% less likely to develop oral and pharynx cancers than those who didn’t drink coffee.
The study, carried out in the US, analysed the outcome of nine previous studies collected by the International Head and Neck Cancer Epidemiology consortium.
The findings were released by the American Association for Cancer Research. LINK

Dental Pulp as source of Stem cells
Analysis of these data demonstrates the promising potential of dental pulp cell collections as a source of cell banks for use in regenerative medicine. Direct reprogramming of patients’ somatic cells would allow for cell transplantation therapy free from immune-mediated rejection. An alternative approach is to establish an iPS cell bank consisting of various human leukocyte antigen (HLA) types. Safety issues must be considered as to which types of somatic cells should be used for such iPS cell banks.  MORE HERE

Now use your digital Camera to Detect Cancer Cells
Using an off-the-shelf digital camera, Rice University biomedical engineers and researchers from the University of Texas M.D. Anderson Cancer Center have created an inexpensive device that is powerful enough to let doctors easily distinguish cancerous cells from healthy cells simply by viewing the LCD monitor on the back of the camera.

Amniotic Membrane to help treat Arthritis

“The objective was to evaluate the utility of cryo-preserved human amniotic membrane (HAM) as a support for repairing human articular cartilage injuries, which have a very limited capacity for self-healing,”
As the current pharmacological and surgical treatments have only palliative effects, cell therapy is a new clinical approach for repairing damaged or destroyed tissues. MORE HERE
