Thermometer (old & new)

It was often a troublesome thing to measure the body 
temperature of children. It took 10~15 minutes in old one.  
Thanks to the advance of microelectronics.  Now it take 
few minutes.

This is a Ear thermometer(OMRON). To measure the 
body temperature, just inserting the ear canal.  
This device can measure the temperature of tympanic 
membrane, using the refraction of infra-red beam.  
But not for suitable in child, since the ear canal of children 
is narrow and often difficult in infants.

What is croup (2) ?


http://www.youtube.com/watch?v=uJ5j4ivnPpc&feature=related

Listen to boy's voice(hoarseness) and strior (coarse musical
sound in breathing). He suffer from " Croup", not the Bronchial
Asthma.

What is Croup (1) ?

            http://fr.youtube.com/watch?v=jTCKpAalkww&feature=related
            Listen her breathing.  hoarse voice is not clear in this video.
          This is not the Bronchial Asthma.
-----------
Croup
----------
Age:        Infant and toddler,  few above 7~10 year old.
Season:   Winter
Etiology:  Virus attack the vocal cord and bronchi
                   (voice box and wind pipe) result the swelling 
                   of it , and airway become  narrow.      

Symptoms:    see and listen above You Tube.
              1) start with slight cough and hoarse voice.
                   and at night suddenly occur the barking cough 
                   , stridor(coarse musical sound in breathing) .
              2) worsening in the night~ mid night and 
                   resolved in noon.  Again worsen at night.
              3) Usually lasts 4~6 days

             ➞     If child seems to be struggling to get a breath
                       go to Emergency medical services immediately !
            
              ☆    Acute epiglottitis due to Haemophlilus influenzae
                       is similar symptoms, but rapidly progress. 
                       Very few in Japan.

Care in home:
           1)  Upright position and using vaporizer in your child room.
           2)  If barking cough and stridor are worsening in 
                the middle of the night, go to Bathroom while 
                the shower on.
           3) Steam almost always works. If it does not, 
                take your child outdoors for a few minutes. 
                Inhaling moist, cool night air may help open the air 
                passages so that she can breathe more freely. 
                If that does not help, call your pediatrician.

Christmas lighting





I have attached the Christmas decoration lights to the 
windows in my clinic.  The light bulbs are made from
LED(Light Emitting Diode), which more powerful lighting
than those of conventional light bulbs.
