Seventy-four pulmonologists and one allergist were recruited to assess the efficacy and safety of iodinated glycerol (Organidin), 60 mg qid, vs placebo in patients with stable chronic obstructive bronchitis in a randomized, double-blind, placebo-controlled, parallel design. A total of 361 patients (180 to iodinated glycerol and 181 to placebo) who complained of cough and difficulty bringing up sputum entered the eight-week study. Evaluations were based upon eight primary symptom efficacy parameters (cough frequency, cough severity, chest discomfort, dyspnea, ease in bringing up sputum, patient and physician global assessments, and a derived patients' global assessment), and six secondary parameters (frequency of aerosol bronchodilator use, incidence and duration of acute exacerbations, frequency of concomitant medication use, incidences of adverse experiences and dropouts). Cough frequency, cough severity, chest discomfort, patients' ease in bringing up sputum, patients' overall condition, and a derived subject global assessment were significantly (p less than 0.05) improved by iodinated glycerol as compared with placebo within eight weeks of treatment. Dyspnea showed a trend toward improvement and the physicians' global evaluation showed no significant difference between groups. Similar findings were noted in a subgroup analysis of moderately-to-severely affected patients. The mean duration (days) of acute exacerbations and number of dropouts attributable to adverse experiences were significantly less (p less than 0.05) in the iodinated glycerol group.(ABSTRACT TRUNCATED AT 250 WORDS)

The above study was carried out in 30 patients, 22 males, 8 females, aged between 30 and 66 years, average age 57.17 +/- 1.43 years, 19 of whom with flare-ups of chronic or asthmatic bronchitis, 6 suffering from flare-ups of chronic bronchoectasic bronchitis, and 5 with acute tracheobronchitis. Treatment with two 300 mg tablets of enoxacin daily lasted from 10 to 15 days. The clinical result was good in 95% of the cases, and microbiological results were also satisfactory in that the micro-organisms isolated were sensitive to the antibiotic. Tolerance was good both locally and generally, only two patients complained of slight stomach discomfort. Both symptoms and laboratory findings improved progressively, and the result was considered excellent in four cases, good in 25 and only fair in one.

Patients with pneumonia or bronchitis were randomized to receive ceftriaxone or cefamandole. A total of 30 of 38 patients were evaluable, 16 in the ceftriaxone group (average age 66.3 years) and 14 in the cefamandole group (average age 69.4 years). All but one had underlying diseases. Patients usually received 1 g of ceftriaxone intravenously every 12 h (mean duration 8.7 days) or 1.5 g of cefamandole intravenously every 6 h (mean duration 8.2 days). Adverse experiences attributable to the drugs were confined to one episode of discomfort at the infusion site in each group. Bacteriological results with ceftriaxone were 83% cured, 11% superinfected after eradication of pretherapy isolate, and 6% failed. Bacteriological results with cefamandole were 76% cured, 24% failed. Clinical results with ceftriaxone were 38% cured, 56% improved, 6% failed. Clinical results with cefamandole were 57% cured, 21% improved, 21% failed. Emergence of a resistant Serratia marcescens was seen in a ceftriaxone-treated patient. Disc diffusion susceptibility testing identified six of the seven pretherapy nonfastidious Gram-negative isolates as susceptible; however, two of the six could not be eradicated with the assigned drug and another two were eradicated with ensuing super-infection with susceptible isolates of Pseudomonas aeruginosa. In contrast, MBCs were an accurate guide to clinical outcome with nonfastidious Gram-negative bacilli.

Transnasal total ethmoidectomy appears to be the surgical treatment of choice for cases of severe polyposis of the ethmoid. A thorough knowledge of the surgical anatomy, special instruments, including a new suction-irrigation-endoscope, and basic concept of flanking surgical measures are prerequisite. On the basis of the experience with 372 interventions, the own technique and results are reported. In a consecutive series of 84 patients, controlled over more than one year postoperatively, a success rate of 83 percent was achieved. The low incidence of complications, and the minimal postoperative discomfort of the patients are emphasized. The method also offers changes for the effective treatment of sinu-bronchitis and bronchial asthma.

A multicenter double-blind randomized trial was performed in 22 teaching hospitals to compare the clinical effectiveness of the combination of amoxicillin (CAS 26787-78-0) plus bromhexine (CAS 3572-43-8) versus amoxicillin alone given 4 times a day for 5 to 7 days in the treatment of clinically diagnosed community-acquired bacterial lower respiratory tract infections. 392 adult patients diagnosed clinically to have acute bronchitis or pneumonia of bacterial etiology were recruited for the study with 192 subjects given amoxicillin (250 mg) plus bromhexine (8 mg) (Drug AB) and 200 receiving amoxicillin (250 mg) (Drug AA) alone 4 times a day for 5 to 7 days. Clinical response, improvement in symptom scores using a visual analogue scale, and bacteriologic response were monitored at Days 3, 5 and 7 of treatment. Results showed that although 180/192 (94%) given Drug AB and 185/200 (93%) given Drug AA had favorable clinical response at the end of treatment, the infection was completely resolved for 89/192 (46%) among the Drug AB group and in 67/200 (34%) of patients on Drug AA (p = 0.022). Also, patients given Drug AB had significantly greater reduction of their symptom scores at Day 3 for symptoms of cough discomfort, cough frequency, ease of expectoration and sputum volume. Among the subset of patients with pneumonia, the cure rates for Drug AB and Drug AA were 24/50 (47%) and 11/50 (22%), respectively (p = 0.008). A respiratory pathogen was cultured in only 72/392 (18%) of subjects.(ABSTRACT TRUNCATED AT 250 WORDS)

Many reports dealing with the toxicity of oil mist in industrial health have been published. The condition appears to be worldwide in distribution and the number of reported cases increases with increasing clinical awareness. In 158 reports published from 1965 to 1993 the following diseases were observed: Skin--contact dermatitis, oil acne and photosensitive allergic dermatitis; Scrotum--benign and malignant tumors; Respiratory system-nasal discomfort symptoms, rhinitis, nasal mucosal dysplasia, nasal mucosal tumor, laryngeal cancer, bronchitis, lipoid pneumonia, lung fibrosis, lung cancer and bronchial asthma; Others--possible carcinogenicity, high incidence of chromosomal change. This shows that oil mist appears to be involved in many industrial diseases, however, cause-and-effect relationship still remains a matter of conjecture; in which exposure dose and/or duration-dependent toxicity is highly probable. Further investigations will be required including immunotoxicological as well as environmental studies for oil mist exposure.

A 72-year-old man was exposed to the sarin gas attack in a Tokyo subway on March 20 th, 1995. After exposure, he noticed eye discomfort, chest tightness, headache and weakness of the lower limbs and oropharyngeal muscles. Despite these symptoms, he visited a hot spring on the same day with his family. On March 25 th, his muscle weakness progressed, and a low grade fever appeared. His muscle weakness disappeared 8 days after exposure to sarin, but respiratory failure rapidly developed, necessitating artificial ventilation within four day after hospitalization on March 28th. Chemotherapy with erythromycin, imipenem/cilastatin, and steroid pulse therapy was begu. PCR and culture of sputum collected by bronchofiberscopy were positive for Legionella pneumophila, serogroup I. His respiratory state improved, but subsequent infection with Pseudomonous aeruginosa. Enterobacter cloacae, and Candida tropicalis/glabrata caused his death 71 days after admission. Oropharyngeal muscle weakness caused by sarin-mediated cholinesterase inhibition was strongly suspected as the cause of hot spring water aspiration. Transbronchial lung biopsy revealed organizing pneumonia with fibrosis. Bronchoscopic findings included redness, edema and fragility of all visible areas of the airway, which was thought to be due to bronchitis caused by Legionellosis.

Cough is probably the most frequent symptom in chest diseases. Hence, a rational and economical diagnostic procedure is essential to prevent unnecessary costs to the health services, i.e. acute bronchitis, a self-limiting disease, which is the most frequent cause for cough should not involve extensive per case costs. History, physical examination, chest X-ray and lung function testing--which constitute both the first and second, i.e. the basic level of a stepwise approach--allows to diagnose causes in most patients with cough. Without evidence of the cause after completing this basic diagnostic procedure patients with acute cough may require blood gases analysis, electrocardiography, echocardiography, lung perfusion study, spiral CT angiography, bronchoscopy or laboratory examinations for diagnosis of pulmonary embolism, aspiration or (seldom) pleuritis sicca. Chronic persistent cough (CPC) is diagnosed if the basic standard approach to chronic cough fails to lead to final diagnosis. Patients will then need further subtle diagnostic management, i.e. bronchial provocation testing, 24 hour pH probe, ENT- or neurological examination, high resolution CT of the thorax and bronchoscopy. We present two algorithms for the rational diagnostic approach to acute (figure 1) and chronic (figure 2) cough. Each algorithm considers spectrum and frequency of causes on the one hand, the positive predictive value, costs and patient discomfort due to the examination on the other. Nonetheless, despite extensive examination up to 20% of patients suffering from CPC the cause remains unclear [11]. Frequently, the capsaicin cough challenge test can reveal an idiopathic upregulation of the cough reflex as the hypothesised underlying condition. Psychogenic cough however, a rare condition in adults should not coincide with hypersensitivity of the cough reflex. Inconsistency and low reproducibility of results of the capsaicin challenge in patients with psychogenic cough preclude his routine clinical use. In conclusion, the very common acute bronchitis and the ACE inhibitor-induced cough do not require any other diagnostic procedure except patient history and physical examination. A simple basic diagnostic approach will usually allow to evaluate acute and chronic cough. In the remaining cases the proposed algorithm should be used for best results and to prevent excessive costs.

A 66-year-old woman was admitted to our hospital because of vomiting and appetite loss. For the 2 days prior to admission, she had a cold, which had developed into acute viral bronchitis on admission. Because laboratory data on admission showed hyponatremia, intravenous infusion of Ringer's lactate solution was started. However, generalized seizures appeared, and she developed a coma on the day of admission. Her plasma antidiuretic hormone (ADH) level was high in the context of a low serum osmolality on the second hospital day. The infusion rate was increased, and the patient's consciousness level returned to normal. However, her normalized serum Na level declined again as she drank much water to reduce throat discomfort. As the throat discomfort caused by the throat inflammation improved with azulene gargling, her water intake was reduced, and the serum Na concentration returned to normal. Thus, polydipsia caused by a throat inflammation partially contributed to hyponatremia in this patient. We note that increased ADH secretion has been reported in adults with acute respiratory infection. Therefore, we concluded that polydipsia caused by the throat inflammation, plus increased ADH secretion, resulted in hyponatremia in this patient. We should pay attention to the behavior of drinking extra fluid in patients with acute respiratory infections.

Gastroesophageal reflux disease (GERD) may cause, trigger or exacerbate many pulmonary diseases. The physiological link between GERD and pulmonary disease has been extensively studied in chronic cough and asthma. A primary care physician often encounters patients with extra esophageal manifestations of GERD in the absence of heartburn. Patients may present with symptoms involving the pulmonary system; noncardiac chest pain; and ear, nose and throat disorders. Local irritation in the esophagus can cause symptoms that vary from indigestion, like chest discomfort and abdominal pain, to coughing and wheezing. If the gastric acid reaches the back of the throat, it may cause a bitter taste in the mouth and/or aspiration of the gastric acid into the lungs. The acid can cause throat irritation, postnasal drip and hoarseness, as well as recurrent cough, chest congestion and lung inflammation leading to asthma and/or bronchitis/ pneumonia. This clinical review examines the potential pathophysiological mechanisms of pulmonary manifestations of GERD. It also reviews relevant clinical information concerning GERD-related chronic cough and asthma. Finally, a potential management strategy for GERD in pulmonary patients is discussed.
