iGrow





The new iGrow isn't the latest Apple product, but instead is a hair growth system. The iGrow uses low-level light therapy to stimulate cellular activity which causes an increase in the natural function of hair follicles. Thicker and fuller hair can be seen in six months. 



Safe



This patented red light technology device is FDA cleared for the treatment of androgenetic alopecia, or male pattern hair loss. This system treats affected areas of the scalp and is the first hands-free low level laser therapy hair growth device cleared by the FDA for use at home. The device must be repeated at intervals to maintain results. The suggested treatment frequency is 3 to 4 sessions per week for about 25 minutes each. Results usually take 4 to 6 months. Once hair growth is achieved, an ongoing maintenance schedule of 1 to 2 sessions per week is strongly recommended to maintain new growth. It can be purchased without a prescription but the cost is about $700 currently.

Antibiotics Linked to Childhood Obesity

The study "Association of Antibiotics in Infancy With Early Childhood Obesity" published in JAMA Pediatrics stated that repeated exposure to broad spectrum antibiotics before the age of two years old is associated with early childhood (2-5 years old) obesity. Sixty-nine percent of the children in the study had taken antibiotics before the age of two. They averaged 2.3 antibiotic courses per child during that time. They also found that broad-spectrum antibiotics put kids at the highest risk compared to narrow-spectrum drugs. They believe that altering the gut microbes, alters digestion of food which changes the amount of calories and how energy gets extracted. Obesity in early childhood is a risk factor for obesity in adulthood, but it's still early enough to intervene and change the outcome. The authors state that using more specific antibiotics, and not broad spectrum antibiotics, might help lower the risk for childhood obesity. This was an observational cohort study so cause and effect can't be determined, but it is an interesting association that could help identify modifiable factors for the risk of obesity during childhood.

Essential Tremor

Essential tremor (ET) is a common neurological disorder with a prevalence estimated of 5% world wide. The incidence of ET increases with age and has a big genetic component to it. ET is treated most effectively by primidone and propranolol. Primidone should be taken 12.5-25 mg/day at bedtime to start out. It can then be titrated up to 250 mg/day in 1 to 2 divided doses.  Doses up to 750mg total per day may be beneficial in ET. Propranolol should be taken 40 mg twice daily to start out, but then increased to a usual maintenance dose of 120-320 mg/day in two divided doses. Common alternative treatments include atenolol, gabapentin, and topiramate.

NLA Cholesterol Guidelines

The National Lipid Association recently released their recommendations for the management of dyslipidemia. The NLA guidelines have a few different thoughts compared to the 2013 AHA/ACC guidelines. One major change is that the NLA has set specific treatment goals for both LDL-C and non-HDL-C based on risk categories and when to consider initiating therapy.

They stated that non-HDL-C is the cholesterol that is carried by all potentially atherogenic particles (root cause of atherosclerosis), which is total cholesterol minus HDL-C.

If a patient is in the desired range, labs and ASVD risk assessment should be repeated in 5 years (or sooner if clinically needed).

Statin Intensity and Benefit Groups

The 2013 ACC/AHA Cholesterol Guidelines stated the different statin intensities, four statin benefit groups and which statin dose each group would benefit the most from.

Low-Intensity Statins
Moderate-Intensity Statins
High-Intensity Statins
daily dose lowers LDL by < 30%
lowers LDL by 30 – 50%
lowers LDL by ≥ 50%

Pravastatin 10 – 20 mg
Lovastatin 20 mg
Simvastatin 10 mg
Fluvastatin 20 – 40 mg
Pitavastatin 1 mg

Simvastatin 20 – 40 mg
Lovastatin 40 mg
Atorvastatin 10 (20) mg
Rosuvastatin 10 (5) mg
Pravastatin 40 (80) mg
Fluvastatin 40 mg BID
Pitavastatin 2 – 4 mg

Atorvastatin 40 – 80 mg
Rosuvastatin 20 (40) mg
Bold = evaluated in RCT, Italics = FDA approved doses but not studied














Four Statin Benefit Groups:

1. Individuals with clinical ASCVD
    - Clinical ASCVD = acute coronary syndromes or history of MI, TIA, stroke, angina, coronary or other arterial revascularization, or peripheral arterial disease 

2. Individuals with primary elevations of LDL ≥190 mg/dL

3. Individuals 40 to 75 years of age with diabetes and LDL 70 to 189 mg/dL without clinical ASCVD

4. Individuals without clinical ASCVD or diabetes who are 40 to 75 years of age and have LDL 70 to 189 mg/dL and an estimated 10-year ASCVD risk of ≥7.5%. This requires a clinician-patient discussion.

What's New for Cholesterol Guidelines

When the ACC/AHA Cholesterol Guidelines were released in November 2013, it changed the view on how to treat high cholesterol. Not everyone in the healthcare field is familiar with the changes in this newer guideline. I had to refresh my memory since it has been a long time since I last looked over it myself.

What's new:

  • No randomized controlled trials that support specific LDL targets
  • New equation used to estimate 10 year ASCVD (arteriosclerotic cardiovascular disease) risk 
    • app for iPhone/Android ASCVD Risk Estimator from ACC/AHA
  • Non-statin therapies do not provide acceptable ASCVD risk reduction benefits compared to their potential adverse effects in the routine prevention of ASCVD
  • There is no data to show that adding a non-statin drug to high-intensity statin therapy will provide incremental ASCVD risk reduction benefit with an acceptable margin of safety
  • 4 statin benefit groups which focus efforts to reduce ASCVD events

Vivotif

The oral Typhoid Vaccine Vivotif for primary immunization should be taken one capsule on alternating days (day 1, 3, 5, 7) for 4 total doses. This should be completed at least one week prior to leaving on your trip. Capsules should be swallowed whole and taken with a glass of water one hour before a meal. Alcohol should be avoided one hour before or two hours after administration since it can disrupt the enteric coating. The capsules need to be stored in a refrigerator. If forgotten and left out of the fridge for less than 12 hours one time it is alright and can be taken regularly as long as they are kept in the fridge for the rest of the course. Once course is finished correctly, protection lasts for 5 years.

Severe Allergic Reactions to OTC Acne Products

The FDA is warning that certain topical acne products can cause rare serious allergic reactions or very severe irritation. You should stop using these products and seek medical help right away if a reaction occurs, such as trouble breathing or swelling of the face. These side effects are more severe than the adverse effect already listed on the products as warnings, such as irritation, minor swelling and redness of the skin. The FDA is not sure what the cause is yet. It could be from salicylic acid, benzoyl peroxide, the inactive ingredients, or a combination of the three.

Invokana

Ivokana (canagliflozan) is a recently approved drug for the treatment of type two diabetes. Approved in the US in 2013. It is a subtype 2 sodium-glucose transport protein inhibitor, or more commonly referred to as a SGLT2 inhibitor. This medication increases urinary glucose excretion by lowering the reabsorption of filtered glucose. Initial dose is 100mg before the first meal of the day. The dose can be increased to 300mg once daily. It is important to drink plenty of fluids to prevent dehydration as more fluids will be excreted through the urine once starting this medication. Common adverse effects include UTI (in women) and an increase in serum potassium. Others include nausea and orthostatic hypotension.

Growing Pains

When I hear the term "growing pains" the first thing I think of is the TV show from 1985-92. But there is condition commonly referred to as growing pains as well, which is usually described as aches or pains in the legs in growing children. There is no evidence that growth in kids hurts, but rather it could be due to a lower pain threshold or overuse of these muscles. Good news is this doesn't cause more severe problems or affects growth. Common treatments include rubbing/massaging legs, using heating pads or taking warm baths, using pain relievers (such as ibuprofen or acetaminophen), and stretching these muscles.

Iron Supplements

For the treatment of iron deficiency, the recommended oral dose in adults is about 150 - 200 mg per day of elemental iron. The key thing to notice is elemental iron since iron supplements come in multiple formulations. A box of ferrous sulfate 325 mg might look like it could be your whole daily dose, but there is actually only 65 mg of elemental iron per tablet.

Influenza Vaccine

It is that time of year again. I gave my first flu shot of the season this afternoon. The flu vaccine is your best defense in preventing the flu. The vaccine can't prevent all cases of the flu since the viruses are always changing. Each year the flu vaccine is set to help against 3 or 4 strains of the virus. It also takes about 2 weeks after receiving the vaccine for protection to develop.

Allegra

Some medications should be taken with food, some need to be on an empty stomach and other medications can be either way. Allegra, the allergy medication, shouldn't be taken with any fruit juices (such as apple, grapefruit, orange) because it can decrease the bioavailability of the medication by up to 36%.

Nutritional Needs

When it comes to vitamins and minerals, the phrase Recommended Daily Allowance or RDA comes up quite often. What does this mean? The RDA is the amount needed to meet the requirements of 97.5% of healthy individuals. Basically enough to prevent deficiencies in almost all of the population. For optimal health, quantities higher than the RDA but lower than the tolerable upper limit may be needed.

Hypomagnesium

There are many potential causes of hypomagnesium including diet, poor absorption and alcoholism. Medications such as loop and thiazide diuretics, some antibiotics, and long term use of proton pump inhibitors can also cause low magnesium. Diabetes is another common cause. If levels are low and you are exhibiting symptoms, such as weakness, muscle cramps, or confusion, your doctor might prescribe you Slow-Mag or something similar. If levels are low and symptoms are more severe than IV magnesium can be given.

Hydrocodone containing products soon to be schedule II

Recently a new law passed to regulate hydrocodone combination products (such as Vicodin, Lortab and generics) as Schedule II controlled substances. This will go into effect on October 6th, 2014. Starting on this date, prescriptions for these products will need a new written prescription for each 30 day supply. If you need a refill, your doctor will have to write a new prescription for you to take to the pharmacy. If needed, your doctor can write three separate prescriptions at the same time. These will have to have a "do not fill until after a certain date" written on them, for up to a potential 90 day supply. This is the same process for other current Schedule II controlled substances.

Sitavig

Sitavig (acyclovir buccal tablets) recently got released in North America for the treatment of recurrent cold sores. One tablet is placed on the upper lip at the first onset of symptoms and dissolves over a few hours. Sitavig is a potential alternative to current oral treatments (which usually last many doses over a few days) and other topical creams/ointments (which need to be reapplied several times a day).

Zostavax

Zostavax, or the shingles vaccination, is stored frozen and needs to be reconstituted immediately once removed from the freezer. Once it is reconstituted it can appear hazy and off-white or pale yellow in color. It is administered as a single 0.65ml dose subcutaneously in the deltoid region of the upper arm. It needs to be administered within 30 minutes of being removed from the freezer. As of now it is scheduled for only a one time dose.
