Acute and chronic eosinophilic pneumonia: clinical evaluation and the criteria.

The clinical courses of 11 cases of eosinophilic pneumonia which were clinico-pathohistologically diagnosed and found to be unassociated with organic disorders producing peripheral blood eosinophilia were extensively investigated and compared with various types of eosinophilic pneumonia previously reported. Five cases of acute eosinophilic pneumonia fulfilled the following criteria: 1) less than a one-month history of symptoms prior to diagnosis, 2) a short clinical course and 3) no recurrence. Six cases of chronic eosinophilic pneumonia fulfilled the following criteria: 1) more than a two-month history of symptoms prior to diagnosis, 2) a prolonged clinical course and 3) recurrence. The results suggested that various types of previously reported eosinophilic pneumonia classified by sex, the presence or absence of peripheral blood eosinophilia, the degree of clinical symptoms or peripheral blood eosinophilia, and the degree of abnormalities on chest X-ray films should be extensively reevaluated.

[A case of endobronchial fibroma associated with recurrent pneumonia].

We present a case of endobronchial fibroma in a 59-year-old man admitted for repeated pneumonia, successfully treated by endoscopic Nd-YAG laser. His chest X-ray showed an infiltrative shadow in the right lower lung field and a mass shadow within the truncus intermedius. Bronchoscopy revealed a polypoid mass with lobulated whitish surface, obstructing 90% of the lumen. A biopsy taken from the tumor was suggestive of fibroma histologically. Two previous case reports stated that endobronchial fibroma readily detaches from the bronchial wall during removal. The tumor was successfully removed without dropping any tumor fragment to obstruct the distal bronchus by means of biopsy forceps manually attached to an endoscope with endoscopic Nd-YAG laser. The resected tumor was mainly composed of collagen fibers with scanty spindle-shaped fibroblastic cells, which was considered consistent with endobronchial fibroma. Endobronchial fibroma is a rare benign lung tumor, and only seven cases have been reported in the Japanese literature. There was no recurrence at three years and nine months.

[Age-dependent alterations in clinical features of pulmonary tuberculosis].

Age-related changes in clinical features of 182 patients diagnosed as having pulmonary tuberculosis from positive culture results of tubercle bacilli were extensively investigated. The percentage of cases detected using mass miniature radiophotography (MMR) was highest in the patients aged 30-39 years, and then decreased with increasing age. It was only 16-19% in those aged 60 years or older. Certain conditions, such as cardiovascular diseases, hypertension, diabetes mellitus, malignancy and other lung diseases, were common in the patients aged 60 years or older. Systemic symptoms, including weight loss and anorexia, and physical abnormalities, including fever and crackles, were common in these patients. Anemia tended to be predominant in the patients aged 60 years or older. The middle/lower lobes were involved more frequently in these patients, in whom the disease distribution was more than one lobe, or disseminated. Positive smear results and negative anergy were more frequently noted in the patients aged 60 years or older. The mortality from tuberculosis in these patients was 4% (7 cases). Although gastrointestinal disorder due to antitubercular drugs was more common in the patients aged 80 years or older, eosinophilia was less frequently observed. Today, improved conditions, better sanitation and the development of new chemotherapeutic agents have contributed to the decline of tuberculosis among the general population. But more efficient procedures that allow the early detection or diagnosis of pulmonary tuberculosis in the elderly should be achieved as soon as possible.

[A comparative study between cefpirome (CPR) and ceftazidime (CAZ) in respiratory tract infections].

Efficacy and safety of a new injectable cephem antibiotic, cefpirome sulfate (hereafter, CPR), against respiratory tract infections were examined and compared with those of a control drug, ceftazidime (hereafter, CAZ). As a rule, CPR 0.5 g twice a day, 1.0 g twice a day, or CAZ 1.0 g twice a day (hereafter CPR 0.5 g group, CPR 1.0 g group, and CAZ group) was administered for 14 days and the following results were obtained. 1. The total number of cases was 470 (155 cases in the CPR 0.5 g group, 160 cases in the CPR 1.0 g group, and 155 cases in the CAZ group). Among them 390 cases were subjected to analyses of clinical efficacy by the efficacy evaluation committee (131 cases in the CPR 0.5 g group, 131 cases in the CPR 1.0 g group and 128 cases in the CAZ group). 2. Efficacy rates determined by the efficacy evaluation committee were 82.4% (108/131) for the CPR 0.5 g group, 81.7% (107/131) for the CPR 1.0 g group, and 83.6% (107/128) for the CAZ group. Efficacy rates determined by the physician in charge were 82.0% (105/128) for the CPR 0.5 g group, 80.5% (99/123) for the CPR 1.0 g group, and 88.5% (108/122) for the CAZ group. No statistically significant difference was observed among the 3 groups. In evaluation of equivalency, clinical efficacy for the CPR 0.5 g group and the CPR 1.0 g group determined by the clinical efficacy evaluation committee was proved to be statistically equivalent to that for the CAZ group. 3. In patients with pneumonia, efficacy rates determined by the efficacy evaluation committee were 87.1% (61/70) for the CPR 0.5 g group, 80.7% (71/88) for the CPR 1.0 g group, and 78.9% (56/71) for the CAZ group. Efficacy rates determined by the physician in charge were 85.3% (58/68) for the CPR 0.5 g group, 80.7% (67/83) for the CPR 1.0 g group, and 86.2% (56/65) for the CAZ group and no statistically significant difference was observed among the 3 groups. In patients with chronic respiratory tract infection, efficacy rates determined by the efficacy evaluation committee were 77.0% (47/61) for the CPR 0.5 g group, 83.7% (36/43) for the CPR 1.0 g group, and 89.5% (51/57) for the CAZ group. Efficacy rates determined by the physician in charge were 78.3% (47/60) for the CPR 0.5 g group, 80.0% (32/40) for the CPR 1.0 g group, and 91.2% (52/57) for the CAZ group. No statistically significant difference was observed among the 3 groups.(ABSTRACT TRUNCATED AT 400 WORDS)

[An optimum dose-finding study of HR810 (CPR) in chronic respiratory tract infections].

In order to determine the optimal dose of cefpirome sulfate (HR810, CPR) against respiratory tract infections (RTI), an optimal dose-finding study was conducted on cases of chronic RTI, and the clinical properties of the drug were compared with those of ceftazidime (CAZ). Inpatients with chronic RTI were randomly assigned to 3 groups: an HR 0.5 g group, receiving 0.5 g X 2/day of CPR an HR 1.0 g group, receiving 1.0 X 2/day of CPR and a CAZ group, receiving 1.0 g X 2/day of CAZ. As a rule, the drugs were administered by intravenous drip infusion for 14 days, after which period clinical efficacy, bacteriological response, safety, and utility were investigated. Of the total 121 cases, 106 were subject to analysis of clinical efficacy, including 38 cases in the HR 0.5 g group, 32 in the HR 1.0 g group, and 36 in the CAZ group. Efficacy rates in the assessment by the committee were 84.2% for the HR 0.5 g group, 75.0% for the HR 1.0 g group, and 86.1% for the CAZ group, without any significant difference between the 3 groups. The bacterial elimination rates were 73.9%, 75.0% m and 88.5%, respectively, without any significant difference between the 3 groups. Associated reactions were noted in 2 of 36 cases in the HR 1.0 g group (eruption and diarrhea), but not in the other 2 groups. The incidence of abnormal clinical laboratory findings was 23.1% in the HR 0.5 g group, 22.2% in the HR 1.0 g group, and 22.5% in the CAZ group, without any significant difference between the 3 groups. Utility rates were 84.2% for the HR 0.5 g group, 74.2% for the HR 1.0 g group, and 86.1% for the CAZ group, without any significant difference between the 3 groups. The HR 0.5 g and 1.0 groups showed no difference in clinical efficacy, bacteriological response, safety, and utility against RTI, and the results of both groups were about equal to those of the CAZ group.

[Bronchial asthma associated with primary lung cancer--comparison of extrathoracic malignancies].

Regarding 249 bronchial asthma patients having been admitted to our division for the recent 9 years, clinical manifestations of 8 bronchial asthma with primary lung cancer (group A; squamous cell carcinoma--5 cases, adenocarcinoma--2 cases, small cell carcinoma--1 case; 3.2% of 249 cases) and 8 asthma patients with extrathoracic malignancy (group B; gastric cancer--3 cases, malignant lymphoma--2 cases, bladder cancer--1 case, laryngeal cancer--1 case, prostatic cancer--1 case) were investigated. In group A, the mean of asthmatic history was 19 years and all cases were associated with respiratory tract infections. Three of 8 patients, were mild type and other 5 were moderate type. In group B, the mean of asthmatic history was 20 years and all cases were involved with respiratory tract infections. Five of 8 patients were mild type and other 3 were moderate type. The mean smoking (Brinkmann) index (1194) in group A was significantly higher than that (166) in 241 asthmatic patients without lung cancer or that (169) in group B. The median survival duration (more than 26 months) of group A patients was significantly lower than that (more than 77 months) of group B. These results suggested that, in many bronchial asthma patients accompanied by primary lung cancer who have adult-typed infectious asthmatic history, smoking exposure and aging are deeply related to the development of lung cancer.

[A case of eosinophilic granuloma of the cervical lymph nodes associated with pulmonary cystic lesions].

A 33-year-old man was referred to our department because of left cervical lymphadenopathy for one month which did not respond to antibiotics. Histological examination of the lymph node biopsy revealed eosinophilic granuloma. However, repeated bronchoscopic examinations performed to evaluate the pulmonary lesions appearing on chest roentgenograms and chest CT scans revealed no evidence of eosinophilic granuloma. Steroid therapy resulted in resolution of the cervical lymphadenopathy, but the pulmonary lesions showed no response. The possible relationship between eosinophilic granuloma and pulmonary cystic lesions in our patient is discussed.

[A case of oral gold tablet-induced interstitial pneumonitis].

A 76-year-old woman was admitted with exertional dyspnea and chest roentgenographical abnormal shadows appearing after oral gold therapy (total 720 mg) for rheumatoid arthritis. Based on the patient's clinical course, chest roentgenograms, chest CT and pathological findings of TBLB specimens, gold pneumonitis was diagnosed. Steroid therapy improved symptoms and pulmonary function and cotton-like shadows on chest roentgenograms and chest CT scanning. However, linear and large ringed shadows on chest roentgenograms and chest CT scan remained, even after steroid therapy. This case is the first case of oral gold tablet-induced pneumonitis. Although the mechanism of oral gold tablet-induced pneumonitis is considered to be almost the same that of gold injection therapy-induced pneumonitis, this case suggested that fibrotic changes in oral gold tablet-induced pneumonitis may be delayed over a long period.

[Smoking among members of the Japan Society of Chest Diseases].

A survey of the smoking habits and attitudes toward smoking among all members of the Japan Society of Chest Diseases has been carried out. Of the 6,224 members of the Society who were sent a voluntary questionnaire, 3,640 (58.5%) responded. Of the 3,640 respondents, 24.8% were smokers, 39.4%, ex-smokers and 35.9%, non-smokers. The prevalence of smoking was lower than among physicians in general in Japan, which is estimated to be 39%, and much lower than the rate for the general male population (61.1%). For ex-smokers, the long-term health risks were the most important reason for giving up smoking, followed by the desire to set an example as medical personnel. The great majority of respondents (91.7-97.3%, depending on smoking status) believed that smoking should be restricted in certain places. Hospitals and clinics had the highest percentage for places where smoking should be restricted. About two-thirds of the respondents also believed smoking should be restricted at medical meetings.

Hydrocortisone inhibits the respiratory burst oxidase from human neutrophils in whole-cell and cell-free systems.

The effects of hydrocortisone on the respiratory burst oxidase (NADPH oxidase, EC 1.6.99.6) from human neutrophils in both whole-cell and full soluble (cell-free) systems were investigated. In the whole-cell system, hydrocortisone inhibited the generation of superoxide by neutrophils exposed to phorbol myristate acetate, suggesting that steroids inhibit the bactericidal capacity of the body in an acute inflammatory phase. Hydrocortisone, which was added to the cuvette after the addition of NADPH and before the addition of sodium dodecyl sulfate, in a cell-free system, was found to inhibit the activation of superoxide-generating NADPH oxidase by sodium dodecyl sulfate. The concentration of hydrocortisone required for 50% inhibition of oxidase was 40 microM. Its inhibition was dose- and time-dependent in the cell-free system. However, hydrocortisone did not alter the Km of the oxidase for NADPH. These results suggest that steroids inhibit the reconstitution of NADPH oxidase by sodium dodecyl sulfate in the cell-free system, and that they do not alter the affinity to NADPH of the oxidase.

[Studies on relationships between the inhibition of human neutrophil NADPH oxidase by anti-inflammatory drugs and development of bacterial infections].

The effects of anti-inflammatory drugs (acetylsalicylic acid, ASA; salicylic acid, SA; indomethacin, IM; hydrocortisone, HC) on the respiratory burst oxidase (NADPH oxidase) from human neutrophils in both whole cell and fully soluble (cell-free) systems were investigated. These drugs were found to inhibit the superoxide generation by human neutrophils exposed to phorbol myristate acetate in a whole cell system and the activation of superoxide-generating NADPH oxidase by sodium dodecyl sulfate in cell-free systems. Concentrations of these drugs required for 50% inhibition of the oxidase (ID50) were; ASA (more than 3.0 mM in the whole cell system and 1.35 mM in the cell-free system), SA (more than 3.0 mM in the whole cell system and 1.30 mM in the cell-free system), IM (180 microM in both systems) and HC (50 microM in the whole cell system and 40 microM in the cell-free system). In addition, these drugs time-dependently inhibited the activation of NADPH oxidase in cell-free systems. In the cell-free system, all of the drugs did not change the Km values for NADPH of the oxidase. These results suggest that these anti-inflammatory drugs, especially HC and IM, inhibit the reconstitution (activation) of neutrophil NADPH oxidase enzyme in the cell-free (whole cell) system.

[A case of pneumonia caused by Chlamydia pneumoniae, strain TWAR].

A case of pneumonia caused by C. pneumoniae, strain TWAR is described in this paper. A 65 year-old male with a persistent dry cough was admitted to our division for left lower lobe infiltrates of the chest X-ray. The serum antibody titers against mycoplasma and some viruses were not elevated, but the serum antibody titers against TWAR reached the maximum level (IgG X 1024, IgA X 256) using microplate immunofluorescence antibody technique (MFA). Isolation of TWAR was tried by BAL and nasophalingial swabs, but were not successful. TBLB from Lt. S10 revealed TWAR inclusion bodies within alveolar epithelial cells using TWAR specific monoclonal antibody (Washington Research Foundation).

[A case of intrapulmonary schwannoma that should be distinguished from lung cancer].

A 32-year-old woman was referred to our division because of abnormal shadow on a chest X-ray film taken at an annual health survey. Chest X-ray films and chest CT scanning revealed a smooth-surface mass at the left hilus. A bronchoscopic examination revealed severe extraluminal compression in the left basal bronchus but no visible tumors. Surgical treatment was performed on the suspicion of lung cancer. Since the intraoperative frozen section examination revealed a benign tumor, the tumor mass was resected. Based on intraoperative and pathological findings, benign intrapulmonary schwannoma associated with the left basal bronchus was diagnosed. Only 15 cases of intrapulmonary schwannoma have been reported in Japan.

[Multiple extra-osseous accumulation of 99mTc-phosphorous compounds bone scintigraphy in small cell lung cancer associated with hypercalcemia].

Bone scintigraphy was performed in a patient with lung cancer of small cell. On bone scintigraphy the increased accumulations in kidneys were observed, while no findings of multiple skeletal accumulations suspected of bone metastases were observed. Four weeks later, when hypercalcemia has been advanced, on repeated bone scintigraphy the extra-skeletal accumulations in such as lung, heart and stomach were shown. These findings indicated that the cause of hypercalcemia in this case was due to not bone metastases but humoral hypercalcemia which the osteolytic substance was produced from tumor. In present paper, the usefulness of bone scintigraphy in hypercalcemia with malignancy, and the mechanism of hypercalcemia have been described and discussed.
