Breaking News: No Link to Femur Fractures Found with Bisphosphonates

Results of a meta–analysis by Dr Dennis Black, of the University of California San Francisco reported online in the New England Journal of Medicine that atypical femoral fractures in patients with osteoporosis are extremely rare and not significantly more common with bisphosphonates. Among more than 14,000 patients involved in three large randomized trials, only 12 fractures of the subtrochanteric or diaphyseal femur were recorded. Data from the Fracture Intervention Trial (FIT) and its five–year extension, which compared alendronate to placebo, were analyzed including the HORIZON Pivotal Fracture Trial, which tested zoledronic acid. However Dr Elizabeth Shane, of Columbia University in New York City, said that drug holidays with careful observation should be considered for  patients with osteoporosis and fracture risk factors who are receiving long–term therapy and are found to have reduced markers of bone turnover.

New form of inhaled insulin may be less risky than Exubera

According to research presented at a chemical society meeting, Afrezza (insulin human {rDNA origin}), a new form of inhaled insulin, appears to help people with diabetes who must use insulin, with fewer potential risks than Exubera (insulin inhaled), an earlier form of inhaled insulin that is no longer on the market.

Afrezza, which is awaiting approval from the US FDA, works faster, keeps blood sugar levels at a closer to normal level, and has less risk of causing hypoglycemia than currently available injectable insulins. It also appears to have less risk of causing lung problems than Exubera.

Meeting Update: Multidisciplinary Head and Neck Cancer Symposium Chandler, AZ • February 25 – 27, 2010

1. PET predicts cancer aggression

Pretreatment PET imaging help predict survival in patients with head and neck squamous cell carcinoma treated with intensity–modulated radiation therapy. Uptake of fluorodeoxy glucose (FDG) tracer in the primary tumor had a significant association with disease–specific survival and a strong trend with overall survival. Nodal uptake of FDG had a significant association with distant disease–free survival. (Dr Min Yao)

2. Elderly can go for aggressive therapy

Older patients benefit as much as younger ones from aggressive chemoradiation for head and neck cancer. Patients ages 70 and older had more toxicity and required more supportive care, but their disease–specific survival, recurrence rate, and patterns of failure did not differ from those of younger patients. (Dr Stephanie A. Michal, Cleveland Clinic)

3. Preserving larynx preserves voice

Larynx preservation led to little difficulty speaking in a majority of five–year survivors of laryngeal and hypopharyngeal cancer with no laryngo–esophageal dysfunction. Among patients treated with induction chemotherapy followed by radiation therapy, 57% had low voice disability and 15% had severe disability. The degree of disability correlated directly with the extent of vocal cord mobility after induction chemotherapy. (Dr Gilles Calais, Hôpital Bretonneau, Tours, France)

4. Lymphedema common in head and neck cancer

Treatment of head and neck cancer causes potentially severe lymphedema, which responds to complete decongestive therapy in most cases. The most severe lymphedema occurred in patients treated with surgery and radiation therapy, followed by definitive surgery alone. Complete decongestive therapy led to clinical improvement in a majority of the patients, including 83% of those treated with surgery alone. (Dr Jan S. Lewin, M.D. Anderson Cancer Center, Houston)

5. Ipsilateral radiation controls tonsil cancer

Patients with newly diagnosed tonsillar cancer can have long–term disease control and minimal risk of contralateral recurrence with ipsilateral radiation therapy. Only two of 102 patients had contralateral failure during a treatment experience dating back to 1970. Ipsilateral radiation therapy resulted in 100% locoregional control at the primary site and ipsilateral neck. (Dr Gregory Chronowski, M.D. Anderson Cancer Center, in Houston)

What’s New

PTU and children: Not to be prescribed as the first line drug in most children or adults. PTU is still preferred to methimazole during the first trimester of pregnancy and in patients with life–threatening thyrotoxicosis or thyroid storm. (Bahn RS, Burch HS, Cooper DS, et al.

Trans fat not more than 2 grams per day

Trans fats are bad for the heart said Dr K K Aggarwal, President, Heart Care Foundation of India and Editor eMedinewS. Though small amounts of Trans fat occurs naturally, most trans fat is artificially produced when vegetable oil is partially hydrogenated. Partial hydrogenation results in fats that are easier to cook with and spoil less easily than naturally occurring oils. They make the food tastier and increase its shelf life.

Trans fat promotes heart disease by elevating LDL, or the "bad" cholesterol, in blood. They go further by lowering one’s HDL—the good cholesterol that actually helps prevent heart disease.

Consumption of saturated fats raises the LDL cholesterol concentration, but does not lower HDL. Thus, while saturated fats adversely affect the lipid profile, they may not be as harmful as trans fatty acids. Trans fatty acids may also interfere with the desaturation and elongation of n–3 (omega–3) fatty acids. These are important for the prevention of heart disease and complications of pregnancy. In an analysis from the Nurses’ Health Study, for each increase of 2 percent of energy from trans fat, the relative risk for incident coronary heart disease was 1.93.

There are no known physiologic benefits related to the consumption of trans fatty acids; thus, reduction in their intake makes sense. Trans fatty acids are a major component of many commercial baked goods, such as cookies and cakes, and most deep–fried foods.

As per American Heart Association one should consume no more than 2 grams of trans fat per day, which is about as much as someone would get from naturally occurring trans fat. The US regulation allows trans fat levels of less than 0.5 grams per serving to be labeled as 0 grams per serving. The best diet is characterized by low amounts of both saturated and trans fatty acids.

Question of the day

What is the basic principle of radiosurgery?

Radiosurgery has been around for nearly a century. Only the terminology is new. It was in 1891 that Jacques Arsene d–Arsonval made a fundamental observation that electrical current above 10,000Hz did not produce muscular stimulation but could ablate and cut tissue. Hence all the modern electrosurgery units work above 10,000Hz.

The commonly used Hyfrecator has a frequency of 500KHz or 500,000Hz or 0.5MHz. The modern radiosurgery units are all clones of the radiosurgery unit manufactured by Dr. Erving Ellman in the 1970s, which works with a frequency of 3.8Mhz.

The question of why 3.8MHz was answered in 1978 by Maness who showed that at this frequency there is least lateral heat conduction on cutting the skin. Since MHz frequency is used for FM radio transmission these newer electrosurgery units, which also work in this frequency, are called Radiosurgery units.


Quote of the Day (Dr Mayur Jain)


Whenever you want to know how rich you are?

Never count your currency, just try to drop a Tear & count how many hands reach out to WIPE it. That’s true richness.

SMS of the Day (Dr Ingole, MD)

It is better to light candle rather than to curse darkness.


Fall update (Dr G M Singh)

What is the evidence that reducing falls actually reduces fractures?

Although most fragility fractures result from falls, the clinical trials of falls prevention interventions tend to have been much smaller than pharma–funded trials of anti-osteoporosis drugs. And only 1–5% of falls result in a fracture. However because  highest risk of second fracture is in the first few months – before drug treatments for bone fragility could work so falls prevention is likely to be crucial despite the lack of direct evidence.

Otitis externa solution

If otitis externa is taking a long time to heal and a whitish, mildew–like substance is seen, local application of 1% clotrimazole solution can help. Apply the solution with a cotton swab twice daily for about 2 weeks.

Dr Good Dr Bad

Situation: A patient with diabetic nephropathy came for diet advice.
Dr Bad: Do not take proteins.
Dr Good: You can take soya proteins.
Lesson: Soy–protein consumption reduces proteinuria in type 2 diabetes with nephropathy. Consumption of soy protein reduced urinary urea nitrogen (–0.9 ± 0.8 vs. 0.2 +/– 0.6 mg/dL, respectively), proteinuria (–78 ± 37 vs. 42 +/– 39 mg/day, respectively), blood sodium (–2 ± 0.04 vs 2.0 ± 0.06 mg/dL, respectively) and serum phosphorus (–0.03 ± 0.2 vs 0.2 ± 0.3 mg/dL, respectively) compared with animal protein. (Ren Nutr 2009 Sep 14). 

Make Sure

Situation: A patient of pulmonary Koch’s talking ATT complained of numbness in fingers and toes.
Reaction: Oh my God! I forgot to prescribe vitamin B complex.

Make sure that in patients talking ATT (including INH) B–complex vitamins (especially vitamin B6) are prescribed to prevent neuropathy. Addition of antioxidants and multivitamins also boost the immune system.

Milestones in Medicine

1928 A.D.Sir Alexander Fleming discovered the germ–killing power of a mold called penicillium, later isolated as penicillin, the first antibiotic.

Mistakes in Clinical Practice

An error, which is more common than it seems to be. There is no need of IV diazepam after an episode of seizures is over. It only prolongs the post ictal drowsiness if given after seizures. Once the seizure is over the emergency is over unless the patient goes into relapse or is a state of status epilepticus. Hence, after an episode of seizures the patient should be started on anti seizure medicines.

Lab Test (Dr Naveen Dang)

CD4 and CD8 test are done to measure the strength of the immune system usually in patients diagnosed with HIV infection.

Readers Responses

  1. Dear Dr Aggarwal, First of all I thank you and congratulate you for updating medical knowledge through eMedinews. You have started a wonderful programme and it is becoming popular with high appreciation among the readers. Despite the unanimous decision taken by the Central Council of IMA against BRMS course the MCI has cleared the course. In my opinion if this new proposal materializes, then, in another 5 years, BRHC holders will numerically outnumber the MBBS degree holder by 3:1. Ultimately they will fight for a short course to achieve MBBS degree and even Postgraduate degrees. Dr.Alex Franklin.

  2. Notice: If you know anyone who has met with a fire accident or people who are born with problems / disabilities such as jointed ear, nose and mouth, they can avail free plastic surgery at Pasam Hospital, Kodaikanal from March 23rd to 4th April 2010 by German Doctors, free of cost.
