[Clinical evaluation of sultamicillin in lower respiratory tract infections].

Clinical efficacy and safety of sultamicillin (SBTPC) in patients with lower respiratory tract infections, mainly pneumonia and bronchitis, have been evaluated in a multicenter trial by 19 institutions in the Kyushu area during a period of 12 months from December 1988 to November 1989. 1. Clinical evaluation was made in 132 patients and efficacy rates of SBTPC were 80.0% (28/35) for pneumonia, 78.5% (73/93) for bronchitis and 100% for the remaining 1 patient with other respiratory tract infections. The overall efficacy rate was 79.1% (102/129). 2. Clinical efficacy rate of SBTPC for respiratory tract infections in patients with underlying diseases such as chronic bronchitis, old pulmonary tuberculosis etc., was 75.0% (60/80) which was not significantly different from the efficacy rate of 85.7% (42/49) in patients without underlying diseases. 3. Of 13 patients who failed to respond to previous antibiotic treatments, 8 (61.5%) were effectively treated with SBTPC. 4. Clinical efficacy rates against infections caused by single species of organisms were 90.9% (10/11) for Haemophilus influenzae, 100% (8/8) for Streptococcus viridans and 100% (3/3) for Staphylococcus aureus. The overall clinical efficacy rate in all cases of monomicrobial infections was 88.6% (31/35), in polymicrobial infection 45.5% (5/11) and the overall efficacy rate in cases in which causative bacteria were identified was 78.3% (35/46). 5. Adverse reactions occurred in 6.8% (9/132) of the patients. The symptoms included allergic reaction in 1 patient, gastrointestinal system disorders in 7 patients and general fatigability in 1 patient. As abnormalities in laboratory test values, elevations of A1-P, GOT, and GPT were observed in 3 patients during the study, but returned to normal after discontinuation of SBTPC administration. 6. SBTPC is a useful antibiotic in the treatment of lower respiratory tract infections under the current medical environment where resistant organisms which produce beta-lactamases have been increasing.

Sarcoid reaction observed in a worker with a history of asbestos exposure.

Bilateral hilar and mediastinal lymphadenopathy was observed in a 32-year-old man who had been engaged in asbestos spraying for 16 years. Lymph nodes obtained from Daniel's biopsy revealed tissue reaction compatible with sarcoidosis. On the other hand, a large number of asbestos particles were detected in the lung tissue from transbronchial lung biopsy and in bronchoalveolar lavage fluid, but no epithelioid granuloma was observed in the lung tissue. Various immunoserological findings such as PPD skin test, serum angiotensin converting enzyme activity, serum beta-glucuronidase and lysozyme level, serum antinuclear antibody, lymphocyte subset of blood and bronchoalveolar lavage fluid were inconsistent with sarcoidosis. However, lymph node enlargement and immunological abnormalities in this patient may be related to asbestos exposure and may not have occurred merely by chance.

Four cases of lung cancer associated with idiopathic interstitial pneumonia.

It is well known that lung cancer develops frequently in patients with idiopathic interstitial pneumonia (IIP) (9.8-22.8%). We investigated 4 patients who developed lung cancer among the 28 patients with IIP (14.3%) who were admitted to our hospital from June 1981 to March 1989. Many reports have pointed out the clinical features of lung cancer associated with IIP as male sex, old age, heavy smoking, and poor prognosis. Our 4 series were agreed with these clinical features. Lung cancer associated with IIP have been often reported to occur in the lower and peripheral regions of the lung, and honeycomb structures are frequently seen. But we found that lung cancer in IIP could actually occur in both the lower and upper regions of the lung and does not occur only in the honeycomb structures. There was no obvious dominance of any histological type among the tumors. If lung cancer is suspected in a patient with IIP, tumor markers are of some value for diagnosis, but are not sensitive enough to be used alone.

Study of asbestos bodies in Japanese urban patients.

To study whether low-level exposure to asbestos contributes to lung cancer risk, the asbestos body (AB) content in lung tissue was measured in 476 patients with lung cancer and 369 patients with other diseases, all from a Japanese industrialized city. Eleven patients with histologically confirmed asbestosis were included. The findings were stratified into four groups. A significant number of patients with lung cancer were seen in the groups with high counts, as compared to controls. There was no significant difference in histologic type and site of lung cancer among four groups. The patients with lung cancer in high count groups were significantly younger than those with lower counts. A significant number of smokers were seen in the groups with high AB counts among patients with lung cancer as compared to controls, even if the patients with asbestosis were excluded. These findings suggest that there may be a positive interaction of smoking and exposure to asbestos relative to the incidence of lung cancer even at a low exposure level.

[Clinical evaluation of sulbactam/cefoperazone in lower respiratory tract infections].

Clinical evaluation, safety and kinetics in serum of sulbactam/cefoperazone (SBT/CPZ) in patients with lower respiratory tract infections have been studied in a multicenter trial participated by 28 institutions in Kyushu area during a period of 13 months from March 1987 to March 1988. 1. Mean peak serum levels of SBT and CPZ in 35 patients up to 4 hours after intravenous infusion of 2 g of SBT/CPZ were 38.2 +/- 17.3 micrograms/ml for SBT and 104.3 +/- 31.4 micrograms/ml for CPZ. Serum half-lives of SBT and CPZ were 0.76 hour and 1.53 hours, respectively. These results were in similar ranges to those reported elsewhere for SBT/CPZ. 2. Serum half-lives of SBT and CPZ after intravenous infusion of 2 g of SBT/CPZ were not significantly prolonged in patients with moderate liver or kidney dysfunctions. 3. Clinical efficacy rates of SBT/CPZ in 217 patients were 93.1% (81/87) for pneumonia, 93.3% (14/15) for lung abscess, 78.9% (15/19) for acute exacerbation of chronic bronchitis, 57.1% (4/7) for diffuse panbronchiolitis, 72.4% (21/29), 74.4% (32/43) and 100% (9/9) for infections concurrent to bronchiectasis, chronic respiratory disease and pulmonary emphysema, respectively. Those were 50% (1/2) for bronchitis associated with lung cancer and 66.7% (4/6) for empyema. The overall efficacy rate was 83.4% (181/217). 4. Clinical efficacy rate of SBT/CPZ for pneumonia in patients with underlying diseases such as lung cancer, pulmonary tuberculosis and pneumoconiosis, etc, was 85.3% (29/34) and was not significantly different from the efficacy rate of 98.1% (52/53) in patients without these underlying diseases. 5. Of 30 patients who failed to respond of previous antibiotic treatments, 21 were effectively treated by SBT/CPZ. 6. Bacteriological eradication rates against Pseudomonas aeruginosa, Haemophilus influenzae and Streptococcus pneumoniae were 42.9% (9/21), 87.5% (14/16) and 100% (5/5), respectively. The overall eradication rate in all cases including polymicrobial infections was 72.8% (67/92). 7. The high levels of peak serum concentration of CPZ, and the difference between serum levels of SBT and of CPZ seemed to contribute to the high clinical efficacy. 8. Adverse reactions occurred in 2.8% (6/217) of the patients, and consisted primarily of rash and diarrhea. Laboratory abnormalities were observed in 8 patients during the study. These were elevations of S-GOT and S-GPT, and eosinophilia. 9. SBT/CPZ is a very useful drug in the treatment of lower respiratory tract infections as it has become available just in time when increase in resistant organisms to beta-lactams is notable.

[Membranous and respiratory bronchiole disease in patients with normal air-flow and mild air-flow limitation].

In order to evaluate the role of membranous (MB) and respiratory bronchioles (RB) in patients with normal and mild airflow limitation, we quantitatively assessed the pathological change of MB, RB and alveoli in the pathological specimens of 42 patients who required surgery for removal of a solitary pulmonary nodule. We also measured the destructive index (DI), to evaluate the destruction of alveolar walls. High resolution CT scan and pulmonary function tests were performed within 1 month of resection. Results of the pulmonary function tests correlated with pathological changes of RB better than with MB. Significant correlation between the emphysema score of resected lung and the pathological change of MB and RB was observed. There was also significant correlations between the CT score or DI and RB changes. However, there was no significant correlation between the CT score or DI and the change of MB. There were significant differences between smokers and nonsmokers in the results of pulmonary function test, pathological changes of RB and severity of emphysema. We postulate that RB is responsible for subtle functional abnormalities in the early stages of chronic obstructive pulmonary disease.

[The marrow granulocyte reserve in lung cancer patients].

The marrow granulocyte reserve (MGR) of patients with lung cancer have been estimated by measuring the maximum neutrophil increment after administration of hydrocortisone. The MGR was found to have decreased in four of 19 untreated patients, but the reason for this decrement was not clear. Further, there were no differences in the MGR between the cell types or cancer stages. The MGR in patients 70 years old or older tended to be decreased. After chemotherapy or radiation therapy, the MGR depressed significantly. However, on administration of OK 432, the MGR significantly increased in two patients who had received radiation therapy and whose MGR had been deficient initially.

A case of giant cell interstitial pneumonia.

This report is of a case of giant cell interstitial pneumonia (GIP) diagnosed by transbronchial lung biopsy (TBLB) and treated effectively with corticosteroid. The patient was a 61-year-old man with cough, dyspnea and findings of diffuse reticular opacities on chest X-ray. In the microscopic section of a biopsied specimen, varied forms of giant cells were observed, some with a cannibalistic appearance. Numerous giant cells and some lymphocytes were also observed in the bronchoalveolar lavage fluid. The possibility of measles pneumonia was ruled out by a negative serum antibody test and the absence of inclusion bodies in the giant cells. The patient had neither a past history of exposure to heavy metals nor to organic dusts. A distinct improvement was obtained with 30 mg of prednisolone administered daily for two weeks and then tapered off gradually.

Endobronchial pseudolymphoma associated with Sjögren's syndrome. Report of a case.

A case of pseudolymphoma occurring in a patient with Sjögren's syndrome is described. The lesion, which gave rise to intraluminal tumor masses in the airway, grew progressively, resulting in severe dyspnea. Treatment with prednisolone brought relief. The lymphoproliferative disorders, the principle clinical manifestation of which was pseudolymphoma, might have given rise to the M-component of the IgA-Ktype.

Synthesis and analgesic activity of novel heterocycles, [1]benzothiopyrano[3,4-b]pyrrole derivatives.

In order to develop analgesic compounds possessing a sulfur atom in the alicyclic ring, novel cis-fused heterocycles, [1]benzothiopyrano[3,4-b]pyrrole derivatives (II) were synthesized via a unique cyclization reaction starting from 4-(4-methoxyphenylthio)-2-butanone (1) or 6-methoxy-3,4-dihydro-2H-1-benzothiopyran-4-one (7). The analgesic effects of benzothiopyranopyrroles (16, 18) were measured by means of the writhing test. The phenolic derivative 18 completely inhibited the appearance of writhing at the dose of 50 mg/kg, but the methoxy derivative 16 had no analgesic effect.

Structure of an anti-plasmin inhibitor, eckol, isolated from the brown alga Ecklonia kurome Okamura and inhibitory activities of its derivatives on plasma plasmin inhibitors.

Eckol (1), a novel phlorotannin with a dibenzo-1,4-dioxin skeleton, has been isolated from the brown alga Ecklonia kurome Okamura as a potent and specific anti-plasmin inhibitor. Its structure has been elucidated based on the spectral data, in particular, by means of negative nuclear Overhauser effect (NOE), and finally established as 1-(3,5-dihydroxyphenoxy)-2,4,7,9-tetrahydroxydibenzo-1,4-dio xin by X-ray analysis. Some partially methoxylated derivatives of eckol were prepared by methylation with diazomethane and also by selective dimethylation of eckol permethylate (1b) to establish the structural requirements for inhibitory activities on alpha 2-macroglobulin and alpha 2-plasmin inhibitor, the main plasmin inhibitors in plasma.

[Deformity of the fingers among women workers at a papermaking mill].

With regard to deformity of the fingers (chiefly Heberden's nodes) frequently occurring in Japan among workers preparing school lunches, an epidemiological study was carried out with a suspicion that this deformity might be an occupational disease. We studied the deformity of fingers among woman employees of a papermaking mill (262 mill workers in comparison with 108 office workers) who excessively use their fingers on the job like workers preparing school lunches. The results of this study showed that the number of mill workers suffering from deformity of the fingers (chiefly Heberden's nodes) was significantly (p less than 0.01) greater than that of office workers. Genetic factor, aging factor and mechanical factor have been cited as the etiological factors for the development of Heberden's nodes. However, our findings suggest that mechanical factor is a more important rather than the genetic or aging factor. As for mechanical factor, we have proposed for the first time that repetition of strong and precise pinching movement with the use of all fingers of both hands is an important factor.

[Trends in the use of antimicrobial agents in Kanagawa Dental College, Hospital].

The development and expansion of antimicrobial agents has made a remarkable improvement. Recently we began to use newqinolon agents, furthermore we began to use the third generation of oral cephem agents. We anticipate we will have a large change of trends in the use of antimicrobial agents. We investigated the trends in the use of antimicrobial agents between April 1st, 1983 to March 31st, 1988, to prepare for the trends in the future. 1) A total use of antimicrobial agents in Kanagawa Dental College, Hospital has increased 19% over the last five year. 2) Trends in the use of injection of antimicrobial agents has decreased over the same period of time, otherwise trends in the use of oral antimicrobial agents has increased tremendously 3) The use of newqinolon agents were less than 0.07% in one year.

[Comparison of high resolution computed tomography and pulmonary function tests in diagnosis of mild emphysema].

To assess the ability of high resolution CT scan and pulmonary function tests in detecting and grading mild emphysema, we correlated the high resolution CT scan and pulmonary function tests with the pathologic grade of emphysema and the destructive index of lung specimens from 42 patients undergoing thoracotomy for solitary pulmonary nodules. Using the high resolution CT scan, we could identify the pathologic grade of mild and moderate emphysema. By measuring diffusing capacity per unit alveolar gas volume (DLco/VA), it seemed to be possible to detect the mildest degree of alveolar destruction assessed by the destructive index, which was not detected by high resolution CT scan. The reason for these results seemed to be that we assessed the severity of emphysema by detecting the air space enlargement on high resolution CT scan images caused by the destruction of alveolar walls, which were detectable by measuring DLco/VA. We conclude that it is possible to detect mild emphysema using the combination of high resolution CT scan and pulmonary function tests.
