 Polar bear “Flocke” in 29 January, 2008.

“Flocke” was born December 2007 in Nuremburg zoo in Germany.  

On January 8th, the zoo decided to separate the baby from mother 

to protect from ”carnivores —–  eating her own baby ” .

Typical face of Kawasaki disease: strawberry tongue, red &

cracked lips, red eyes and skin rash.

Edema & erythema of hand, skin rashes
Edema & erythema of foot, maculo-rash also noted.
Skin desquamation(peeling) begin fingertips at convalescent stage

In 1967, Dr. Tomisaku Kawasaki(Japanese Red Cross Central Hospital of Tokyo)

reported the first cases of Kawasaki disease in a Japanese Journal(1). I think,

this paper is one of the best papers in clinical medicine. He described in the

details of the symptoms, signs and clinical course of patients with many photos.

Later, in 1974, he reported a paper of MLNS(=Kawasaki disease) in the official

Journal of American Academy of Pediatrics(2). However, this English version

was not well described, as comparing to the Japanese one.

Since started as pediatrician in 1975, I have been interesting the etiology of

Kawasaki disease. One day in 1992, Human herpesvirus-6 was isolated from

blood sample of 4-month-old patients, but not another patients(3). The case

might have been co-incidental.

Today in Japan, the total numbers of patients is around 6.000 ~ 9,000 cases/year.

The searches for the causative microbe such as bacterias, viruses and fungus

have been failed.

In the summer of 1994, I experienced an epidemic of whooping cough like

illness at an Junior high school in Yamaguchi Prefecture. I had consulted,

performed the physical examination, collected the sera, and taken the swabs

for the cultures of viruses and bacterias from the students with severe cough.

|||||||A 13 year-old boy had started the cough, rhinorrea and sore throat on

|||||||with chest pain and was worsening during night without whooping.

|||||||During June 22 and 23, he had fever with maximum temperature of 38.4°C.

||||||||The physical examination on June 25 showed normal findings including

||||||||1% band, 60% segmented, 3% eosinophils, 1% basophils, 1% monocytes

||||||||and 34% lymphocytes. The C-reactive protein was negative. The cold

||||||||agglutinin titres were 1:32 (normal range <1:32).

|||||||||The Minocycline and cough remedies were prescribed upon a diagnosis

A 15 year-old boy started the coughing on June 8. During June 9

and 11,he had fever with maximum temperature of 39.3°C. The cough

was associated with chest pain,nausea or vomiting and worsened night

without whoop. On June 20, he consulted a pediatrician of local hospital.

On physical examination, moist rale was audible in right lower lung.

The chest radiograph showed the infiltration in perihilar and right lower

area.

was 4.7mg/dl. The cold agglutinin titers was 1:128.

Clarithromycin and cough remedies were prescribed with a tentative

diagnosis of Mycoplasma pneumoniae infection. The cough was waned

gradually and lasted to July 6. The culture of Bordetella species,

Mycoplazma pneumoniae and viruses were all negative.

In the beginning of June 1994. A telephone call from a school doctor of Mito

Junior High School, to my laboratory room, when I had been working as a

lecturer in the Department of Pediatrics, Yamaguchi University School of

Medicine.

Said ——- “ A numbers of students have been suffering from severe

||||||||||||||||||||||||||||coughing illness in my school. It is something different

||||||||||||||||||||||||||||from that of mycoplasma infection. Do you suggest me other idea ? “

It was summer, hot weather in Yamaguchi. It is curious phenomenonto such an

epidemic was occurred among junior high school students. After the phone call,

I decided to investigate this epidemic and to determine the causative microbe.

||||||||||||||||||||||Photo: Mito Junior High School, Ooda, Yamaguchi, Japan. 1994.

My first thought of causative microbes was a type of adenoviruses, bordetella

pertussis, or parapertussis. However, the culture for viruses, bacterias were all

negative. And finally, Chlamydia pnuemoniae was identified by the methods of

antibody titres and PCR analysis with the aids of Dr. Kazunobu Ouchi( 2nd

department of Pediatrics, Kawasaki Medical School).

→　http://www.kawasaki-m.ac.jp/pediatrics2/

This was unexpected for me. Because previous reports of Chlamydia pneumoniae

infection showed that the clinical picture was similar to that of Mycoplazuma

pneumoniae infection. But in this epidemic the character of cough was different

from any other coughing illness.

I named this coughing illness as ” chlamydia cold “, or “chlamydia flu”.

||||||||||||||||||||||The cough occurred continuously and worsened during the night

||||||||||||||||||||||and early in the morning. The cough became more severe during

||||||||||||||||||||||the first week, but no patients had whooping or cough paroxysms.

||||||||||||||||||||||The mean duration of cough in cases with URI was 17.4 days and

I havest the sweet corn(maize), which  cultivate in my small garden.

After boiling, I try to eat ——-  sweet taste , but something harder 

than that of  supermarket’s one —— its too late to harvest, I think.
