BCG vaccine



-----------------------------------
BCG vaccine in Japan
-----------------------------------
In 1967, the injection method of Bacillus Calmette et Guérin(BCG 
vaccine was changed from intradermal injection into 18-needles
-press method in Japan.  I don't know the real reason. Probably, 
this method is remained less skin scars at injection site.

----------------------------------Photo:   brown ampule contain Freezed dry BCG vaccine,  
---------------------------------------------Right; 9-needles device.


BCG vaccine was originally produced by French researchers, 
Drs. Calmette and Guérin in Pasteur institute. They attenuated 
Mycobacterium bovis by sequential passage of cultures.

In 1934, Dr. Kiyoshi Shiga (http://en.wikipedia.org/wiki/Kiyoshi_Shiga
, the discoverer of shigella, the bacilluscausing dysentery )
 introduced this strain into Japan.

The side effect of Japan made-BCG vaccine(Tokyo 172 strain), 
such as subaxillary lymph node's swelling , is very few.
---------------------------------One month after BCG injection.  
---------------------------------Note the small abscesses at inoculation sites.

C-reactive protein

----------------------
C-reactive Protein
----------------------
C-Reactive protein is named for its property of precipitating with
the group-specific C polysaccharides of the cell wall of the
pneumococcus in the presence of Ca ions. It was discovered in
1941 by Dr. MacLeod and Avey.

    Acute phase protein
    M.Wt.                           : 110,000~ 144,000
    site of production       : liver
    Normal serum value :  less than 1.0 mg/100ml
    Increased in :   acute infections and inflammatory change 
                            or necrosis.
    measurement method:  precipitation with specific antiserum.

WBC count: past & present

                 → http://www.horiba.com/medical-diagnostics/
             You can measure to Leukocyte, Red blood cell, Hb
             Ht ; Platelet. using whole blood of 20 micro-litter.

Leukocyte count
---------------------------------
We, pediatricians frequently have been order to measure White
Blood Cells(leukocyte) and its differential, as described in the
clinical records of first human trial on penicillin.

At present, the counting of white blood cell is very easy to do
, less than 5 minutes.  Doctors need no technician.

In the past, the enumeration of leukocyte was counting manually
using Hemacytometer under light microscope.

Manual determination of White Blood Cells :
1) a few micro-litter of whole blood were filled to the pipette.
2) diluted with stain solution, and squeeze gently several times.
3) charge Neubauer Hemacytometer with stained blood.
4) using 100x magnification, count leukocytes in the 4 corner
     squares( total: 16 corners), of the counting camber.
5) multiply number of leukocytes counted by 50 = Total WBC
     count. if 210 leukocytes are counted, total count is 210x50=
     10,500/cu mm.

Cough or cold medicines


There are a variety of over-the-counter cough or cold medicines 
(syrup) for children are sold in Drug stores in Japan. Its taste and 
flavor are excellent if you drink, in spite of its contain bitter codeine.           

The ingredients of OTC cold medicine ;
------------------------------------------------------------------------
1) Cough suppressant: many contain codeine phosphate,                 
    and dl-methylephedorine or dextromethorohan HBr.
2) Anti-histamine: d- Chloropheniramine
3) Expectorant: guanethidine sulfate
4) Fever reducer: acetaminophen
5) Vitamins: B1, B2, C
6) Caffeine
-------------------------------------------------------------------------    

Usually, Pediatrician prescribe 1),2),3),4) with the various combination 
of its volume and ingredients, depending upon the child condition. 
But not use 5), 6).  

1) Be careful !   Please buy the child-resistant Safely caps. 
2) In mild cold case, it may OK to use OTC drugs. 
3) The cost of OTC cold drugs is expensive. 

We pediatricians prescribe more reasonable and effective cold medicines, 
but, Public Insurances regulate its cost too much lower.  I can’t accept 
this Japan Insurance Policy.

Staphyloccal Scalded Skin Syndrome in child

-----------------------------------------------------------
Staphylococcal scalded skin syndrome in child
----------------------------------------------------------
SSSS arises mainly in the newborn infant, rarely in older child,
because they possess the antibody against the exfoliative toxin
A or B.

Staphyloccal Scalded Skin Syndrome in mouse

Photo: SSSS in ddY mouse. Upper 2 mouses were subcutaneously injected
---------with different doses of the Staphylococcus aureus which were cultured 
---------from the SSSS patient. Lower one was the control(St. aureus, Cowan I )
----------(provided by Dr Hisanori Konishi, Department of Bacteriology, 
-----------Yamaguchi University School of Medicine)

--------------------------------------------------------------
--------------------------------------------------------------
The disease is caused by strains of Staphylococcal aureus, which
produce exofoliative toxins(A or B), which absorbed, cause the
separation of cells within epidermis.

The Staphylococcal aureus, which isolated from the baby with
this disease, was cultured and then Mouse(ddY) was inoculated
subcutaneously with the its Staphylococci. A positive Nikolsky
sign(peeling of skin) indicate the epidermolytic activity or
presence of exfoliative toxins.

Staphyloccal Scalded Skin Syndrome in newborn


Staphylococcal scalded skin syndrome in newborn baby;
reddishness around the neck skin and peeling(another case of this story).

Staphylococcus aureus in human skin
(Dr. Dennis Kunkel, Dennis Kunkel Microscopy, Inc. Kailua, HI )

----------------------------------------------------
Staphylococcal scalded skin syndrome
----------------------------------------------------

In early spring 1990, a newborn with
staphylococcal scalded
skin syndrome (=SSSS) came to the Department of Pediatrics,
Yamaguchi University Hospital and subsequently another 2
babies came to the outpatient clinic. Those 3 babies were born
at maternity unit of University Hospital.

The staff of maternity unit had tried to control of this staphylo-
coccus infection. So the rooms, linen, curtains, gowns, and
floors were cleaned with a disinfectants and heavy hand
washings were ordered to the staffs . But the outbreak of SSSS
continued.

The Professor of Pediatrics asked me any idea to stop of this
outbreak. In that time, I didn't knew where and when staphylo-
coccus was transmitted to newborn baby ? I went to Library
and found one paper from Guy’s Hospital, London.
It described as follow;

We described two outbreaks of staphylococcal skin infection
among neonates, Aged from 3 to 16 dates, who were delivered
in the maternity unit at Guy’s Hospital. The first outbreak,
which included six babies, began in mid-February1986 and
lasted for a period of 10 days; second, began exactly 4 weeks
later, involved a further possible nine babies and resolved in
14 days. We wish to draw attention to the work that all of this
caused, the procedures used to identify the epidemic strain,
and to show how the two outbreaks were connected by
persistent nasal carriage by one member of hospital staff.

I showed this paper to the chief of the committee for Hospital
Infection Control. Then the committee conducted same method
as described by Guy's Hospital and succeeded to control this
outbreak.
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
1990: A outbreak of neonatal SSSS in Maternity unit.
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
(only show the cases which extensive bacterial examination
were done)
May 1990 : 2 cases
June: 1 case
July: 1 case
August: 3 cases
September: 3 cases -------- and no cases after.

# The carrier of our case: Staphylococcus aureus (MRSA and
produced exofoliative toxin) were isolated from nasal swabs
of 2 obstetrician.

I thank you to Docters of Guy's Hospital of London.

-----------------------------------------------------------------------------
then, We visited the Department of Pediatrics, Children's Medical


Dr. Margaret Hammerschlag is a chief of department, a specialist
in Chlamydia pneumoniae infection in children, and the author of
the chapter " Chlamydia pneumoniae infection" in the textbook of
Pediatric Infectious Disease.


Her laboratory is to be said that the rate of Chlamydia pneumoniae's
isolation from patients is the best in the world. A Pediatrician from
the Kurume University school of Medicine was studied there.
We stayed 3 days in New York.

We stayed 5 nights in San Francisco and moved to Vanderbilt University,
Nashville, where a colleague of my University studied there for the research
on Helicobacter Pylori.


I walked around the Hospital, Faculty of Medicine and Laboratory, and also
the University campus at random direction. It's good place for study I think.
Nashville is not noisy city, also gave me a good impression.
