New C. difficile guidelines

Two professional societies (Society for Healthcare Epidemiology of America and the Infectious Diseases Society of America) have issued updated Clostridium difficile guidelines to address epidemiologic and treatment changes since guidelines were first released in 1995.The update was published in the May Infection Control and Hospital Epidemiology

  1. In the last 15 years, new more virulent strain of C. difficile has been identified.

  2. New dates shows decreased effectiveness of metronidazole in severe disease.

  3. While stool culture is the most sensitive test, it is not clinically practical due to slow turnaround time.

  4. Toxin testing is most important clinically, but lacks sensitivity.

  5. A potential strategy is to employ a two–step method that uses enzyme immunoassay testing of glutamate dehydrogenase (GDH) as initial screening, and then uses the cell cytotoxicity assay or toxigenic culture as the confirmatory test for GDH–positive stool specimens. Results seem to differ based on the GDH kit used, so this is an interim recommendation.

  6. Polymerase chain reaction (PCR) testing seems to be rapid, sensitive and specific, but more data are needed before it can be recommended for routine testing.

  7. Repeat testing during the same episode of diarrhea is discouraged, as it has limited value.

  8. Use metronidazole for an initial episode of mild–to–moderate C. difficile infection (CDI). The dosage is 500 mg orally three times per day for 10 to 14 days.

  9. For an initial episode of severe CDI, use vancomycin. The dosage is 125 mg orally four times per day for 10 to 14 days.

  10. For the first recurrence of CDI, usually use the same regimen as the initial episode, though stratify by disease severity.

  11. For the second or later recurrence, use vancomycin with a tapered and/or pulse regimen.

  12. Do not use metronidazole after the first recurrence or for long–term chronic therapy, due to the potential for cumulative neurotoxicity.

Medpage Meeting Notes: American College of Cardiology
Atlanta, GA • March 14 – 16, 2010

1. Pushing blood pressure too low may be harmful

Lower is not necessarily better for blood pressure control in patients with diabetes and coronary artery disease.
There was no difference in a composite endpoint of death, myocardial infarction, or stroke between patients with an average systolic pressure 130–140 mm Hg and those with a lower average pressure, according to Rhonda Cooper–DeHoff, of the University of Florida in Gainesville. Patients who had uncontrolled systolic blood pressure (140 mm Hg and higher) had significantly increased cardiovascular risk. Patients who were most tightly controlled, however, had an increased risk of all–cause mortality compared with those in the middle range, during both the trial and an extended follow–up of about five years.

2. BP variability linked to adverse CV outcomes

Hypertensive patients with the most variability in blood pressure between healthcare visits have a greater risk of stroke and coronary heart disease than patients with more stable pressure. In an analysis of the Anglo–Scandinavian Cardiac Outcomes Trial –– Blood Pressure Lowering Arm (ASCOT–BPLA), mean blood pressure during the study weakly predicted stroke risk and was not associated with risk of adverse cardiovascular outcomes.Visit–to–visit variability in blood pressure, however, acted as a strong predictor of both, such that patients with the most variability had a fourfold increased risk of stroke and a threefold increased risk of coronary heart disease events. One is better off with a higher pressure and less variability than a lower pressure and more variability.

3. Dual action antihypertensive outperforms ARB alone

A novel agent that counteracts vasoconstriction as both an angiotensin receptor blocker (ARB) and neprilysin inhibitor appears to fight hypertension better than an ARB alone. LCZ696 reduced diastolic pressure by a mean of 2.17 mm Hg (P<0.0001) more than comparable doses of the ARB valsartan (Diovan) upon which it is based. (Dr Luis M. Ruilope, of the Hospital 12 de Octubre in Madrid).

4. Close lipid and BP control fail in diabetes

Intensive blood pressure and lipid management does little against elevated cardiovascular risk in diabetes, according to results from the ACCORD study. Using a blood pressure target of 120 mm Hg rather than the general population standard of 140 did not reduce the primary outcome of nonfatal MI, nonfatal stroke, and death from cardiovascular causes. (Dr William C. Cushman, VA Medical Center Memphis, Tenn). Likewise, adding fenofibrate to standard statin therapy did not reduce the major adverse cardiovascular events (Dr Henry C. Ginsberg, Columbia University New York City). (NEJM)

What’s New: Oral bicarbonate for CKD

In a randomized trial, treatment with oral bicarbonate slowed progression of chronic kidney disease and improved nutritional status of patients with creatinine clearances between 15 and 30 mL/min per 1.73 m2. (de Brito–Ashurst, I, Varagunam M, Raftery,MJ, Yaqoob, MM. Bicarbonate supplementation slows progression of CKD and improves nutritional status. J Am Soc Nephrol 2009;20:2075.)

10th Perfect Health Parade in the Capital

Flagging off the 10th Perfect Health Parade from Jantar Mantar outside Commonwealth Games Office, Shri Suresh Kalmadi, Chairman, Commonwealth Games 2010 said that New Delhi is prepared to host the Commonwealth Games. He also released special tableaus – one talking about the problems faced by the widows and their children and the second on "Green Delhi" focusing on Delhi Transport Corporation’s preparations for the forthcoming Commonwealth Games. He said that widows and their children should be given a priority in the community.

The parade was organized by Heart Care Foundation of India and the Loomba Trust to create health awareness in general and the health of the widows and their children in particular. The associated partners of the event were Department of Health, Delhi Government, MCD, NDMC, Deptt. of WCD (Prohibition) Govt. of Delhi, New Delhi and Janak Puri Branches of IMA, World Fellowship of Religions and M/s Bhatnagar & Sons.

The parade in the form of tableaus made on the style of the Republic day parade, created awareness about the health issues faced by the widows and DTC’s preparedness for the forthcoming Commonwealth Games.

Present on the occasion, Mr. Raj Loomba founder trustee and Chairman of The Loomba Trust said that like in the West, India should also celebrate 23rd June as International Widows Day. He also read out a message by Ms Preiti Zinta, the Brand ambassador of The Loomba Trust, who in her message said that free education should be provided to the children of widows.

Padma Shri and Dr BC Roy Awardee Dr KK Aggarwal, President Heart Care Foundation of India, said that widows are at a higher risk of heart attack, diabetes and paralysis.The problems faced by the widows are psychological depression, social disorganization, insecurity, health deterioration, dependence on others, deviance and delinquency.

Acharya Dr Sadhvi Sadhna Ji Maharaj, Shri Naresh Kumar, IAS, CMD DTC, Ms Nalini Kamalini, famous Kathak Dancers, Dr NK. Yadav, MHO, MCD, Dr PK Sharma, MOH, NDMC, Dr KS Bhaghotia, CMO, DHS, Dr AK Kansal, President IMA Janak Puri Branch, Dr Sanjay Sood, President IMA New Delhi Branch etc. were also present at the flagging–off ceremony.

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 can 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 1970’s radiosurgery unit manufactured by Dr. Erving Ellman, which works with a frequency of 3.8 Mhz. 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.

Radiosurgery equipment: The radiosurgery equipment consists of electric and electronic circuits to take in 220Volts of current at 60Hz frequency and give out 380,00,000 Hz or other high frequency output. These frequencies are modulated by rectifiers and filters to give electrons which vibrate at 380,00,000 times per second and have various unique attributes.

As end users we either want electrons to either cut the skin or coagulate the skin.

These electrons generated are delivered to the skin by either a single electrodemonopolar or two electrode–bipolar. This is the active electrode. The electrons transmitted by the active electrode are collected by the antenna plate, which could be called passive electrode. Whether the passive electrode has to be in contact with the patient skin or not has to be ascertained according to the manufacturers recommendation.

The challenge of compliance

Maintain a "compliance book." This contains details, such as the patient’s phone number or that of a friend or relative, and information about medications and appointments. These patients are called daily by a staff member to inquire about their progress, to remind them to do certain tests (eg, blood glucose), or to help them remember scheduled visits.


Dr Good Dr Bad

Situation: A diabetic patient with allergy had high eosinophil count.

Dr Bad: The two are unrelated.

Dr Good: Get urine Microalbumin and triglyceride tests done.

Lesson: Allergic disorders may be associated with microalbuminuria in men with type 2 diabetes. Eosinophil count was positively associated with systolic BP, serum triglyceride concentration and albumin excretion rate in men. (Clin J Am Soc Nephrol 2009 Oct 1).


Make Sure

Situation: A lady took her daughter to the physician for not gaining weight.

Reaction: Doctor, inspite of munching something or the other all day long, my daughter is not gaining weight

Make sure that besides "munching" large quantities she also eats some quality food containing balanced amount of macro as well as micronutrients.
