Hepatodiaphragmatic interposition of the colon (Chilaiditi syndrome) is considered to be rare conditions. The incidence of this condition is not exactly known in Japan. In order to know this incidence, we reviewed 116, 825 roentgenograms of chest mass survey, and detected 17 cases (0.015%) of Chilaiditi syndrome. The condition was observed in 6 males (0.016%) and 11 females (0.014%). The average age of the males was 68, 7, of the females 66.5. The frequency tends to increase with age, and no difference in two sexes was observed

Various forms of blood dyscrasias may produce chest X-ray abnormalities which are characteristic of each entity.
I) Of the diseases with decreased erythrocyte counts, long-standing iron-deficiency anemia will produce cardiomegaly which is characteristically free of development of pulmonary edema through-out the course of the disease. On the contrary, megaloblastic anemia is frequently accompanied by heart failure and pulmonary congestion.
In polycythemia, pulmonary vascular markings appear dilated and tortuous and remain so long even after effective treatment.
II) In leukemia, abnormal chest X-ray findings can be classified into five types.
1. Increased lung markings
2. Bronchopneumonia or lobar pneumonia
3. Enlarged hilar shadow
4. Disseminated densities
5. Tumor formation
Overall incidence of abnormal chest findings was 49.4% in cases with acute and 84.696 of those with chronic leukemia.
Histological studies of lung sections established that these X-ray findings are primarily the result of the presence of leukemic cells in the alveolar septal vessels or their extravascular infiltration, in association with superimposed edema, congestion, hemorrhage, infection, fibrosis or thromboembolism in various combinations.
III) Immunosuppression is not uncommon in blood dyscrasia. Especially during the course of steroid therapy, the possibilities of such complications as miliary tuberculosis or other infection, and the infestation of Pneumocystis Carinii should be kept in mind

Basing upon the informations obtained from analysing the radiographical lesions on chest film, the investigation was carried out to find useful parameters in the diagnosis and the treatment for the patients with lung cancer by elucidating the relationship between its prognosis, the radiographical appearance in the progression of the lesion and the various histological types.
Clinical materials consisted of 68 patients with adenocarcinoma and 78 patients with squamous cell carcinoma, all of them were underwent to surgical intervention and were postoperatively followed up regularly.
The study was done by comperatively analysing the tomographic findings obtained just prior to operation, the resected lungs checked in anatomically segmental fashion. The radiographical findings were classified according to the relationship between the location and size of tumor and pulmonary structure (pleura, bronchi, pulmonary arteries and veins, and lymph nodes). Further investigation was done for correlating the change seen on the chest X-ray film to the term period postoperatively in which the recurrence or metastases appeared clinically.
Ninety per cent of the pulmonary lesions with adenocarcinoma were located just beneath the visceral pleura and possessed intense pleural indentation, and this pleural indentation can be identified radiographically over 90% of cases.
Histologically, they were classified into four types; Po (not reached), P₁ (reached but not invaded), P₂ (invaded) and P₃ (invaded up to parietal pleura), and its extent of lesion is closely related with its prognosis. It has been noted that its prognosis became worse when the longest diameter exceeds over 3cm.
When considering these two findings in combination, namely in the cases with adenocarcinoma radiographically proven to have pleural indentation and tumor diameter of 3 cm, it appeared that 80% of cases would result to have metastases within one to three years postoperatively. Even in the cases with its lesion less than 3cm, the incidence of metastasis was noted to be 50% within the postoperative period of one to three years.
The pulmonary lesions due to squamous cell carcinoma can be divided patho-anatomically into the cancerous lesion extending into mucous membrane and the lesion deeply penetrating (the lesion partially invading pulmonary parenchyma extending over the outer layer of the bronchial membrane). The former results in the stenotic or obstructive lesion in the bronchial lumen and as the result of these lesions, the secondary lesions such as obstructive pneumonitis and atelectasis will develop. The latter will result in tumor formation which will produce the stenotic or obstructive lesions to the pulmonary arteries or veins adjacent to bronchus. Therefore, the extent of cancerous lesion within the bronchial lumen can be radiographically suspected by careful investigation of the degree of its secondary change, and also the location, size and degree of tumorous lesion by checking in decrease or absence of vascular shadow.
Basing upon the radiographical informations obtained from above-mentioned, analytical methods, the prognosis seems to be good in 80% in the cases with squamous cell carcinoma which originated within the area peripherally to subsegmental-bronchus but not extending proximally to segmental-bronchus.
In contrary, the cases with squamous cell carcinoma originating peripheral area invading up to segmental-bronchus or even to the large proximal bronchus or the squamous cell carcinoma originating at the bronchus proximally to segmental bronchus, one third of cases are considered to be inoperable or underwent to only conservative operation, and even one third of cases, underwent to surgical intervention, developed to have the recurrence or metastases within the follow-up period of three years. Especially, one fourth of case swith the primary lesion located in the segmental bronchus B⁶ were r

Thirty-five cases of 6 collagen diseases were collected to study chest-roentgenological signs as comparing with autopsy findings during the period of thirteen years from 1958 through 1970 in Sagamihara National Hospital. They are consisted of 19 cases of systemic lupus erythematodes including 6 autopsies, 3 autopsy cases of polyarteritis nodosa, 8 cases of systemic scleroderma including 3 autopsies, an autopsy case of rheumatic fever, 2 autopsy cases of rheumatoid arthritis, and 2 autopsy cases of Wegener's granulomatosis.
Conclusions obtained were as follows;
(1) Some abnormal roentgenological findings were noted in 32 of 35 cases examined; Abnormalities interpreted as pneumonitis in 25, cardiac enlargement in 21 and pleural effusion in 22 cases.
(2) Abnormal shadows were found in 17 of 19 systemic lupus erythematodes; abnormalities interpreted as pneumonitis in 12, pleural effusion in 11 and pericarditis in 12 cases.
(3) Abnormalities were found in 2 of 3 polyarteritis nodosa; hilar vascular prominence in 2, single or multiple nodules in 2, cardiac enlargement in 2 and butterfly-shaped shadow in a case.
(4) All cases of 8 systemic scleroderma had some abnormalities in chest roentgenograms; pulmonary fibrosis in 7, ring-like appearance in 6 and cardiac enlargment in 4 cases.
(5) Peumonitis, cardiac enlargement and pulmonary edema were demonstrated in a case of rheumatic fever.
(6) Both of two cases of rheumatoid arthritis had abnormal shadows; pneumonitis, pulmonary fibrosis and cardiac enlargement in both cases.
(7) A large mass with cavitation was demonstrated in a case of Wegener's granulomatosis, and multiple nodular shadows of various size were present in another case, and in both cases perivasculitis and bronchopneumonia were found.
(8) Non-specific bacterial bronchopneumonia was found in 11 of 35 various collagen diseases.
(9) The combinations of the above various roentgenological signs might be able to play an important role in differentiation of each collagen diseases

Sarcoidosis, which had been studied mainly in the field of dermatology, had been interested widely since the international congress on sarcoidosis in 1958, and many investigations on sarcoidosis has been reported in japan. Nevertheless, the essential parts of the disease, i. e. pathogenesis and etiology have not been clarified, and the conclusive remarks would be obtained in future.
In this paper, the characteristics on chest x-ray film of sarcoidosis were compared with those on similar diseases, like as bronchiectasis, fibrosis (bronchogenic-, peribronchial-), chronic bronchitis, pneumonitis, miliary carcinosis, miliary tuberculosis, pneumoconiosis and Hodgkin's disease etc.
Basing on these findings, improvement of the diffusing capacity in sarcoidosis was observed and it runs parallel with the abnormality in chest x-ray film, and this finding differs from Marshall and Ting et al.

Two cases of Warthin's tumor were experienced among 24 operated cases of tumors of salivary glands since 1965 at our surgical service.
The first case was 64-years-old male, and had had tumor of about 5 cm diameter at the left subauricular region for 10 years.
The second case was 72-years-old female, and had had tumor at the right subauricular region for 3 years.
Both cases were diagnosed as benign tumor, and were operated upon on Nov. 5, 1970 and May 26, 1970, respectively.
Histological examination revealed they were Warthin's tumor.
In the literature, 48 cases of the tumor, including our 2 cases, are reported in Japan since 1935. Among them, 33 tumors were originated from the parotid gland.
Although no malignant evidence was reported histologically and clinically, extirpation of the tumor may be recommended.
