Therapeutic effects of lividomycin (LVDM) were studied in 33 patients with respiratory infections including pneumonia, lung abscess, chronic bronchitis, etc. LVDM was intramuscularly administered at the dose of 1 or 2 g per day for consecutive 4 to 25 days. The results obtained are summarized below: 1. At the end of the first week of the treatment, rate of improvement in such parameters as cough, sputum, rales, fever and blood sedimentation rate were 69%, 56.7%, 60%, 79.2% and 70% respectively. Also, in 16% of the patients, abnormal shadow noted in X-ray film of the chest was disappeared and in 20% of the patients, size of the same was reduced during the first week of treatment. 2. Therapeutic effects of LVDM were evaluated synthetically and were graded as excellent, good, fair and ineffective. LVDM was effective in about 70 per cent of the patients, that is, excellent results were obtained in 4 patients, good in 12 patients, fair in 6 patients, and in 10 patients this antibiotic was ineffective. 3. In one patient with slight loss of high frequency perception was observed on the audiogram, but no other ototoxic effects such as subjective hearing loss, tinnitus, etc. In addition, no untoward effects on renal and hepatic function were observed. 4. The MIC values of LVDM for clinically isolated 20 strains of Pseudomonas aeruginosa were examined, using kanamycin for comparison. The MIC values of LVDM for many strains were superior to those of kanamycin. In view of the test results mentioned above, LVDM would appear to be useful medication for the treatment of some of respiratory infections.

In 31 adult patients with cystic fibrosis (CF) who were chronically infected with Pseudomonas aeruginosa we examined the effect of giving regular three monthly oral ciprofloxacin. Patients received ciprofloxacin or placebo for 10 days every 3 months for 1 yr in a randomized, double-blind, placebo-controlled study. During each course of treatment patients receiving ciprofloxacin reported an improvement in cough, sputum production and peak expiratory flow (PEF) P = < 0.005. During the year of study patients receiving ciprofloxacin showed an improvement in PEF when compared with those receiving placebo (P = < 0.05) but the changes in FEV1 and FVC were not statistically different in either group. Regular oral ciprofloxacin was well tolerated but did not prevent hospital admissions or reduce the number of courses of intravenous antibiotics throughout the year. The median MIC to ciprofloxacin in the active treatment group rose from 0.5 mg l-1 to 0.75 mg l-1 during treatment. We conclude that CF patients are likely to benefit from oral ciprofloxacin for exacerbations of respiratory symptoms. However, regular treatment with ciprofloxacin over 1 yr improves PEF but does not reduce the rate of hospital admissions with acute exacerbations of respiratory symptoms.

Primary sarcomas of the great vessels are rare, but the most common site is the inferior vena cava. Herein are reported five new cases arising from the pulmonary veins with clinicopathologic correlation and comparison to previously reported cases. All new cases occurred in women ranging in age from 23 to 64 years at diagnosis (mean, 56 years). They had symptoms suggestive of left heart failure, including three patients with dyspnea, one with hemoptysis, and one with cough. Three cases showed tumor extension along the pulmonary veins into the left atrium. Tumors ranged in size from 2.8 to 7 cm in greatest dimension. Histologically, all were leiomyosarcomas. They were highly cellular tumors. Three cases had predominantly spindle cell morphology and two were predominantly epithelioid; one had foci of calcification. Most showed extensive necrosis. All tumors were reactive with antibodies to actin and desmin. Two cases were reactive with antibodies to MIC-2 (dotlike); two cases showed reactivity to keratin antibodies; and two showed reactivity for estrogen, progesterone receptor protein, or both. None were positive for antibodies to S-100 protein. All cases were treated with surgical excision. Follow-up ranged from 2 months to 21 years (mean, 4.8 years). Two patients were alive and well; two were alive with metastases; and one died of disease. Pulmonary vein sarcomas represent intermediate- to high-grade leiomyosarcoma. Although often lethal, complete surgical excision can lead to long-term survival. They occur predominantly in women and may express hormone receptors. Therefore, hormonal manipulation may offer promise as adjuvant therapy.

Forty nine subjects with acute bacterial exacerbations of chronic bronchitis (ABECB) treated with grepafloxacin were evaluated for parameters predictive of clinical outcome. Signs and symptoms associated with ABECB were serially collected and evaluated for changes. Coughs per day, sputum volume and the percentage of sputum neutrophils were associated with clinical outcome. A by groups analysis, based on clinical success was performed using Cox regression analysis to determine factors associated with time to clinical success and time to reduction in sputum volume, coughs per day and sputum neutrophil percent. Factors evaluated included AUIC (AUC/MIC), isolate species, years and type of underlying lung disease, alcohol use, smoking history and number of ABECB within the previous 12 months. AUIC<276 (mg h/l)/mg/l (P<0.03) and or the presence of mild bronchiectasis (P<0.01) were associated with longer time to clinical success. In addition a relationship was found between AUIC>212 (mg h/l)/mg/l (P<0.01) and AUIC>576 (mg h/l)/mg/l (P<0.02) and decreasing days to sputum volume reduction and coughs per day, respectively. A diagnosis of mild bronchiectasis prolonged the time to reduce coughs per day (P<0.03) and neutrophil percentage (P<0.01). Patients with mild bronchiectasis were found to have an increase in the time to clinical success, coughs per day improvement and sputum neutrophil percent improvement. AUIC is an important PK/PD parameter predictive of successful outcome in ABECB, even in subjects with mild bronchiectasis. Grepafloxicin has been withdrawn from sale since these studies were carried out. This work is published to illustrate the relationship between pharmacodynamics and clinical efficacy and the use of AUIC as a valuable predictive parameter for fluoroquinolones.

We encountered a case of pulmonary nocardiosis that responded dramatically to combined ST and sparfloxacin treatment. A 55-year-old woman presented with fever, cough and yellowish sputum. She had been under treatment with oral prednisolone (15 mg per day) since July 1997 after a diagnosis of Evans syndrome. A high fever of 39.8 degrees C was noted on January 30, 1998. The patient was hospitalized for bloody sputum, bilateral hypochondriac pain and evidence of infiltrative opacities in the left lower lobe on chest radiography. Bacterial pneumonia was suspected, and she was treated with piperacillin, but her clinical symptoms did not improve. Sputum culture and serologic examination failed to lead to a definitive diagnosis. Nocardia farcinica was isolated by culturing tissue obtained by CT-guided transcutaneous pulmonary biopsy, leading to a diagnosis of pulmonary nocardiosis. The results of an MIC test for antimicrobial agents led to treatment with a combination of ST and sparfloxacin, and the clinical symptoms improved. These clinical observations suggest that, when pneumonia is diagnosed in patients who have been receiving oral steroids for a prolonged period, pulmonary nocardiosis should be considered in the differential diagnosis to enable selection of appropriate antimicrobial agents.

We presented a case of pulmonary Rhizops microsporus var. rhizopodiformis infection which developed abruptly during treatment of bronchial asthma by systemic corticosteroids. The patient, an 85 year-old-woman, was given systemic steroid therapy for 15 days. She suddenly became febrile two days after the therapy and was coughing up yellow sputum. Chest X-ray film showed multiple nodules with cavities which became worsened rapidly. A specimen of sputum culture gave a growth of Mucoraceae, which was identified to be Rhizopus microsporus var. rhizopodiformis. She was given amphotericin B and miconazole was added on the basis of MIC value of the strain. Although she improved initially, her clinical course showed neutropenia, pseudomembranous enterocolitis, malnutrition, and then died after about six months. Because the diagnosis of pulmonary mucormycosis is difficult and prognosis is poor, further studies for investigating clinical features would be necessary.

Daucus carota L. (Family: Apiaceae alt. Umbelliferae), commonly known as 'wild carrot' or 'Queen Anne's-lace,' is an ecologically invasive erect biennial naturalized to Scotland. The ethnobotanical uses of this species include applications in the treatment of cough, diarrhea, dysentery, cancer, malaria and tumors, and as an antiseptic, abortifacient, aphrodisiac, carminative, stimulant, stomachic and tonic. The major constituents isolated from the methanol extract of D. carota seeds by reversed-phase preparative high performance chromatography were luteolin, luteolin 3'-O-beta-D-glucopyranoside and luteolin 4'-O-beta-D-glucopyranoside, three flavones. The constituents were assessed for their antibacterial and free radical scavenging activities, as well as toxicity towards brine shrimp. Among these three flavones, luteolin showed the highest degree of free radical scavenging activity (RC50 = 4.3 x 10(-4) mg/mL) in the 2,2-diphenyl-1-picrylhydrazyl (DPPH) assay. Both luteolin and its 4'-O-glucoside demonstrated bactericidal activity against Staphylococcus aureus and Escherichia coli (Minimum Inhibitory Concentration [MIC] = 5.0 x 10(-2) - 1.0 x 10(-1) mg/mL). Luteolin also demonstrated antibactericidal activity against Bacillus cereus and Citrobacter freundii (MIC = 5.0 x 10(-2) mg/mL). Luteolin 3'-O-glucoside showed bactericidal activity against Bacillus cereus and Lactobacillus plantarum (MIC = 2.5 x 10(-1) mg/mL and 5 x 10(-1) mg/ mL, respectively). In the brine shrimp lethality assay, the LD50 value of luteolin was 5.3 x 10(-2) mg/mL, and that of its 3'-O-glucoside and 4'-O-glucoside were > 1.0 mg/mL.

In neuromuscular disorders, reduced peak cough flows (PCFs) are considered to increase the risk of respiratory complications such as pneumonia or chronic atelectasis. Different methods were described to improve PCF. However, these studies were primarily carried out in adults, and there is limited information regarding the use and efficacy of these methods in children with respiratory muscle weakness. The aim of this study was to investigate whether hyperinsufflation with an intermittent positive-pressure breathing (IPPB) device is effective in cough augmentation in pediatric patients. Spirometry (forced inspiratory vital capacity, FIVC; forced expiratory volume in 1 sec, FEV1), respiratory muscle pressures (peak inspiratory pressure, PIP; peak expiratory pressure, PEP), and PCF were measured in 29 schoolchildren with various neuromuscular disorders. IPPB-assisted hyperinsufflation was taught individually to increase lung volumes (maximum insufflation capacity, MIC) above FIVC. The impact of hyperinsufflation on peak cough flow was documented. In 28/29 patients, IPPB-assisted hyperinsufflation enhanced FIVC from 0.68 +/- 0.40 l to an MIC of 1.05 +/- 0.47 l (P < 0.001). Unassisted PCF was 119.0 +/- 57.7 l/min, and increased to 194.5 +/- 74.9 l/min (P < 0.001) in 27/29 patients. This effect was similar in young patients (ages 6-10 years) and older patients (aged >10 years). Augmentation of lung volumes from FIVC to MIC correlated with an increase of PCF (R = 0.42, P < 0.05). IPPB-assisted hyperinsufflation improves PCF in pediatric neuromuscular disorders. The results suggest that this technique can be used to improve clearance of airway secretions and therefore reduce respiratory morbidity in children with NMD.

An 80-year-old woman presenting with fever and cough was given a diagnosis of community-acquired pneumonia. She was hospitalized and treated with ampicillin/sulbactam (ABPC/SBT) and clarithromycin (CAM). Gram stain images and sputum culture results led us to believe that the causative agent was Haemophilus influenzae. Drug sensitivity testing indicated that the H. influenzae was a beta-lactamase-positive, ABPC-resistant (BLPAR) strain. Treatment with ABPC/SBT was not clinically effective. We considered the possibility of beta-lactamase-positive amoxicillin/clavulanate-resistant (BLPACR) strains. Further testing revealed that the MIC of ABPC was 128 microg/ml, that of SBT/ABPC was 8 microg/ml, and that of AMPC/CVA was 4 microg/ml. Furthermore, genetic analysis indicated the H. influenzae to be a BLPACR-I strain. The poor clinical course eventually led to a diagnosis of BLPACR. When beta-lactamase-producing H. influenzae is cultured, the possibility of a BLPACR strain resistant to ABPC/SBT and AMPC/CVA must be considered.

Primary sarcomas of lung are rare compared to metastatic sarcomas. Herein, we report a rare case of primary pulmonary synovial sarcoma with polypoid endobronchial growth in a 35-year-old lady who presented with cough and dyspnea. A malignant pulmonary tumor was suspected and left pneumonectomy was performed. Grossly, a non-encapsulated polypoidal endobronchial tumor measuring 6 cm in greatest diameter, with a solid, tan-white cut surface was identified. Microscopically, tumor was characterized by a proliferation of oval to spindle-shaped cells arranged in sheets and fascicles. Focal hemangiopericytomatous pattern was noted. Immunohistochemically, tumor cells were positive for vimentin, BCL-2, MIC-2 and calponin and focally positive for pancytokeratin and epithelial membrane antigen. A subsequent molecular analysis performed using reverse transcriptase-polymerase chain reaction with RNA extracted from paraffin-embedded tissue, revealed SYT/SSX1 fusion gene which confirmed the diagnosis of synovial sarcoma. The utility of immunohistochemistry and molecular techniques in diagnosis of such a rare case is stressed and the relevant literature is discussed.
