Spirometry for Asthma Diagnosis


There is no single precise test to diagnose asthma,hence has to be based on patterns of symptoms and response to therapy over the time.However Spirometry test aids in asthma diagnosis and its management .In this test Forced Expiration Volume in 1 second [FEV1] is measured followed by administration of bronchodilator like salbutamol . If the improvement in FEV1 is greater than 12% it is supportive of diagnosis 

What causes asthma

Asthma is caused by various factors like environmental,genetic,medical conditions .The effect of these factors on Asthma is partially  understood/known
Environmental: The low quality of air due to traffic pollution or high ozone level,smoking during pregnancy ,exposure to indoor allergens like dust mites,cockroaches,mold etc or exposure to indoor volatile organic compounds may trigger Asthma attack.
 Genetic:The genes related to immune system and inflammation modulators which are hereditary is a risk factor for asthma.Some times genetic variations take place when combined with environmental exposures which have role in asthma
Medical Condition:previous history of Atopic disease is a strong risk factor for asthma.and also the asthma attack is high in patients with eczema or hay fever.Obesity has co relationship with asthma.Beta blockers,NSAIDS,Ace -inhibitors ,Aspirin may trigger asthma.

Who are at more risk of asthma? Adults or Children, females or Males ?


Asthma generally affects all  age groups but often starts in childhood.Children who often have respiratory infections and wheeze often are at higher risk of developing asthma.In United States , there are  around 25 million with asthma among which more than 7 million are children.
    When it comes to sex , girls have less asthma than boys which is quite opposite in adults where more women have asthma than men.But as of now, role of sex hormones in asthma is not known.

what actually happens in asthma?(Process)


The airways which carry air into and out of lungs gets inflamed which makes airways  very sensitive and swollen .These sensitive airways react strongly to few inhaled substances(triggers).This reaction leads to muscle tighten around them in turn narrows airways causing reduced air flow to lungs.
                 Also,airways may make more mucus(sticky thick liquid) than normal which further blocks(narrows) air way .All these in a chain might result in asthma symptoms

Symptoms of Asthma


Symptoms of Asthma may include shortness of breath,wheezing,chest tightness, cough.These symptoms are worse at night or early in the morning or in response to physical exercise .People with asthma may have marked and persistent symptoms rarely with most of the people experience them usually in response to triggers

what is asthma ?

Asthma is a chronic lung disease  in which inflammation and narrowing of airways occur.This causes recurring periods of wheezing,shortness of breath ,cough and chest tightness.
      Genetic and environmental factors may be the cause of Asthma

Elecsys anti Mullerian Hormone (AMH) , a new fertility test for assessment of ovarian reserve for pregnancy

Elecsys anti Mullerian Hormone (AMH) , a new fertility test for assessment of  ovarian reserve  for pregnancy is introduced by Roche with  increased accuracy when compared to conventional methods.
                    Anti Mullerian Hormone is a vital fertility marker used in health care to assess ovarian reserve levels.This Elecsys Anti-Mullerian Hormone[AMH] blood test can be measured during any day of menstrual cycle which produces standardized results for ovarian reserve assessment in comparison to ultrasound which often depend on clinic or operator person.
                   This Elecys  AMH blood test will be available in all markets accepting CE mark in Latin America,Europe,Asia,Middle east,Africa.
Anti Mullerian hormone is a protein hormone (dimeric glycoprotein) which is structurally related to inhibin and also activin belonging to family TGF-β (transforming growth factor]. AMH is expressed by granulosa cells of the ovary during reproductive years .By inhibiting excessive follicular selection by FSH , it limits the formation of primary follicles.

Guaifenesin AC for Viral infections

Guaifenesin AC is a combination of Guaifenesin(an expectorant*) and Codeine phosphate(an anti tussive*) .This drug is used in treatment of cough and chest congestion due to viral infections like Flu or common cold and other respiratory diseases.
             This combination is used only for short term/temporary infections and not for long term breathing problems.
       Guaifenesin AC can be administered with 4 to 6 hours intervals. Don not exceed the prescribed dose . When symptoms of over dosing like irregular heart beat, loss of consciousness ,slow or shallow breathing etc are seen contact your doctor immediately

*Expectorant -It increases the amount of hydration of secretions(respiratory) , resulting in more yet clearer secretion and as a consequence lubricating the irritated respiratory tract .
*Antitussive- a cough suppressant

Cough still continues after Viral infection

Post viral Cough is a condition that follows viral respiratory tract infections like Flu or Common cold . This usually happens because the receptors that were responsible for cough stimulation during previous infection are up reugulated and continue to stimulate after the virus is eliminated.
    This condition usually goes away on its own . However  increase in cardiac activity such as jogging ,running and other related cardiac activities help .
Cough suppressant drugs containing codeine may help .

Radio Frequency Ablation(RFA) for Lung Cancer treatment

Radio frequency ablation (RFA) is a form of electrical energy and Ablation means killing completely.In Radio frequency ablation electrical energy heats up the the tumour cells and kill them.
      In Radio frequency ablation a small probe like a needle goes through the skin of the chest directly in to the tumour.This process is done under  computerized tomography(CT Scan) so that it is made sure probe is in exactly correct place . The electrode in the probe creates radiofrequency  energy to produce heat and consequently kill/destroy cancer(tumor) cell.The patient will be under anesthesia the whole process.
  Radio Frequency Ablaton(RFA) can be employed in patients with early stage non small cell lung cancer, who do not want to have conventional surgery and also for advanced lung cancer where tumour is blocking airway resulting in breathelessness  .
      Side effects of RA ablation include small discomfort and pain in the treatment area,feel tired , getting air in to chest cavity which usually  goes away with no treatment in few days.

Tramadol use in treatment of Pain

Tramadol is used to treat moderate to moderately severe pain . The extended release from of Tramadol is for around the clock treatment of pain.
    Tramadol is an opioid  analgesic which has two different mechanisms of action(MOA). 1.By binding to  μ-opioid receptors.  2.By inhibiting re-uptake of serotonin and norepinephrine ( Neurotransmitters which play important role in mood ).When administered Tramadol is metabolized to O-desmethyltramol which is significantly more potent opioid .
               It's analgesic effect initiates 1 hour after oral administration and reaches to peak effect in 2 to 4 hours . Common adverse effects include diziness, nause,vertigo,constipation , headache,vomitting, somnolance.
      Tramadol is first  developed and marketed as "Tramal"by Grunenthal GmbH ,a German company in 1977 .It is now available with brand names Conzip,Rybix,Ryzolt,Ultram,Ultram ER,ODT.
