On the Virus Pneumonia Discovered in the Northern Mountain Regions of Okayama Prefecture

Ever since June 1956 mainly centering around Hayashino, Mimasakacho, the mountain regions in the northern part of Okayama Prefecture we have frequently encountered virus pneumonia which by their roentgenographs were misdiagnosed for pulmonary tuberculosis. By November of the same year there appeared the patients indicative of virus pneumonia from their roentgenographs of chest, among pupils of such grade schools as Hayashino, Toyokuni, Toyoda, Narahara, and Kumon Grade Schools, all around Hayashino. Therefore, indirect x-ray photographs had been taken of 2, 019 pupils and found 381 cases whose shadow indicated what might be thought to be of virus pneumonia. We present herewith a report on x-ray findings of thes cases, percentage of the position of shadow appearance, clinical symptoms as well as on x-ray differentiation

On the Two Cases of What are Thought to be "Porzellangallenblase"

The application of x-rays in the diagnosis of gall-bladder diseases is an old, well-known method, but since this is used mainly in taking a simple photograph, it is difficult to obtain a good roentgenological picture. Recently with the successive advent of excellent opaque substances such as Biligrafin, Telepaque and Priodax the diagnosis of gall bladder diseases has become quite easy, but two cases on which we report here are, on the contrary, the cases whose diagnosis has been made more difficult on account of the appearance of these excellent contrast media. This "Porzellangallenblase" is an extremely rare disease and it was first reported by H. D. Flörchen (1929) in the "Zentralblatt d. Chirurgie". It presents a piture identical with the one taken at the time when opaque substance is administered. As for the symptoms, the patient mainly complains of something similar to gall-stone; and in our cases, one was suspected of kidney stone and the other was of gall-bladder disease. Both of these were discovered at the x-ray examinations of the stomach, and each in their roentgenograph presented the stone in their bile duct. In addition their roentgenograph of the gall-bladder gave the picture identical with the one taken when opaque substance had been given. We present this case report as these are very rare cases among Japanese people in the light of available literatures
