Due to a low acceptance of active immunisation against Bordetella pertussis, whooping cough continues to be a frequent childhood disease in parts of Germany. The age distribution in the lower Rhine area showed a peak incidence at 4.3 years of age, whereas 11% of all cases were observed in infants, and 6% were observed in adults. A significant sex difference was not found in children suffering from pertussis; in adult patients, however, women were more often affected. Whooping cough occurred during the whole year, its peak incidence was found during early winter. In children, paroxysmal coughing fits, vomiting and whooping were the primary symptoms of disease; adults and infants, however, developed these symptoms only in reduced frequency. About 25% of all cases showed an atypical course, and could only be diagnosed by laboratory tests. While leukocyte count and ESR did not have diagnostic significance, a combination of microbiological and serological tests showed a high diagnostic sensitivity and specificity. In contrast to the former GDR and to most European neighbours, the former Federal Republic overrated the side effects of active vaccination as compared to the various risks of natural infection. This resulted in a decline of vaccine acceptance to less than 10% in several areas of the former FRG. It is anticipated that the altered recommendation in favour of vaccination, and especially the future application of acellular vaccines with less side effects, will result in the elimination of whooping cough in all areas of Germany.

Eighty-two patients were hospitalized following an accidental exposure to chlorine. All patients presented with dyspnoea and cough. The other symptoms included irritation of throat (53.6%), irritation of eyes (42.3%), headache (29.2%), abdominal pain (26.8%), vomiting (24.3%) and giddiness (9.7%). All of them had bronchospasm and 5 (6%) had cyanosis at the onset. An x-ray of the chest revealed patchy infiltrates in 3 (3.85%) and hilar congestion in 2 (2.44%). Pulmonary function tests showed an obstructive pattern in 27.4%, restrictive in 3.25% and mixed in 53.2%. Pulmonary functions were normal in 16.1% of the patients. Bronchoscopy revealed tracheobronchial mucosal congestion in all cases, hemorrhagic spots in 35.7%, erosions and ulcers in 12.5%. All patients were treated with oxygen, aminophylline, hydrocortisone and antibiotics. Haematemesis (n = 1) and pulmonary oedema (n = 2) developed 12 hours after the admission. Two other patients developed pneumonia 48 hours later. All patients recovered satisfactorily. On follow-up 16 patients had no sequelae after one year. Pulmonary functions were normal in 5 patients after 3 years of follow-up.

Cough variant asthma is characterized as a persistent, nonproductive cough with minimal or no wheezing and dyspnea. The diagnosis can be overlooked or misdisagnosed. We describe the severity of cough, the misery of some patients who have this syndrome and the usefulness of a diagnostic-therapeutic trial in ten patients with cough variant asthma. We evaluated ten patients whose chief complaint was persistent nonproductive cough. During the course of evaluation, all patients received a diagnostic-therapeutic trial of prednisone for cough variant asthma after other major causes of cough had been excluded. The duration of cough ranged from 2 months to 20 years. Some patients had significant side effects from coughing including interference with social life, work and sleep, urinary incontinence, stool incontinence, hoarseness, and vomiting. After a diagnostic-therapeutic trial with prednisone, nine patients reported significant improvement of cough in three days. One patient required 2 weeks of therapy for optimal improvement. All were subsequently controlled primarily with inhaled conticosteroids. The diagnosis of cough variant asthma may not be made for a prolonged time. A short course of prednisone as a diagnostic-therapeutic trial can establish a diagnosis and be followed by an effective method of control of cough by inhaled corticosteroids.

Regional variations in the discharge patterns of the internal and external intercostal muscles of the middle and caudad thorax were studied in decerebrate, spontaneously breathing cats during coughing and vomiting. Coughing, induced by electrical stimulation of the superior laryngeal nerves, consisted of increased and prolonged diaphragmatic activity followed by a burst of abdominal activity. Mid-thoracic external and internal intercostal muscles discharged synchronously with the diaphragm and abdominal muscles, respectively. Caudal external and internal intercostal muscles, however, discharged synchronously with the abdominal muscles. Vomiting, induced by stimulation of the lower thoracic vagi, consisted of a series of synchronous bursts of diaphragmatic and abdominal activity (retching) followed by a prolonged abdominal discharge after the cessation of diaphragmatic activity (expulsion). Caudal external and internal intercostals discharged in phase with diaphragmatic and abdominal activity but both mid-thoracic intercostal muscles discharged out of phase with these muscles. These results indicate major differences in the control and functional roles of intercostal muscles at different thoracic levels during these behaviours.

1. Cellular properties were studied before and after bath application of the dihydropyridine L-type calcium channel antagonist nimodipine in aging and young rabbit hippocampal CA1 pyramidal cells in vitro. Various concentrations of nimodipine, ranging from 10 nM to 10 microM, were tested to investigate age- and concentration-dependent effects on cellular excitability. Drug studies were performed on a population of neurons at similar holding potentials to equate voltage-dependent effects. The properties studied under current-clamp conditions included steady-state current-voltage relations (I-V), the amplitude and integrated area of the postburst afterhyperpolarization (AHP), accommodation to a prolonged depolarizing current pulse (spike frequency adaptation), and single action-potential waveform characteristics following synaptic activation. 2. Numerous aging-related differences in cellular properties were noted. Aging hippocampal CA1 neurons exhibited significantly larger postburst AHPs (both the amplitude and the integrated area were enhanced). Aging CA1 neurons also exhibited more hyperpolarized resting membrane potentials with a concomitant decrease in input resistance. When cells were grouped to equate resting potentials, no differences in input resistance were noted, but the AHPs were still significantly larger in aging neurons. Aging CA1 neurons also fired fewer action potentials during a prolonged depolarizing current injection than young CA1 neurons. 3. Nimodipine decreased both the peak amplitude and the integrated area of the AHP in an age- and concentration-dependent manner. At concentrations as low as 100 nM, nimodipine significantly reduced the AHP in aging CA1 neurons. In young CA1 neurons, nimodipine decreased the AHP only at 10 microM. No effects on input resistance or action-potential characteristics were seen. 4. Nimodipine increased excitability in an age- and concentration-dependent manner by decreasing spike frequency accommodation (increasing the number of action potentials during prolonged depolarizing current injection). In aging CA1 neurons, this effect was significant at concentrations as low as 10 nM. In young CA1 neurons, nimodipine decreased accommodation only at higher concentrations (> or = 1.0 microM). 5. We conclude that aging CA1 neurons were less excitable than young neurons. In aging hippocampus, nimodipine restores excitability, as measured by size of the AHP and degree of accommodation, to levels closely resembling those of young adult CA1 neurons. These actions of nimodipine on aging CA1 hippocampal neurons may partly underlie the drug's notable ability to improve associative learning in aging rabbits and other mammals. Reversal of inhibitory postsynaptic potentials (IPSPs) by chloride ion and/or current injections into six motoneurons revealed the presence of inhibition during the period between phrenic bursts during fictive vomiting and also during the final phase of expulsion when phrenic discharge ceased by abdominal discharge continued. 3. Fictive coughing, evoked by repetitive electrical stimulation of superior laryngeal nerve afferents, was characterized by a large phrenic discharge followed immediately by a large abdominal nerve discharge. During fictive coughing, phrenic motoneurons retained their ramplike depolarizations throughout phrenic discharge; however, the amplitude of depolarization was greater than during inspiration. During the subsequent abdominal nerve discharge, the phrenic membrane potential usually underwent an initial rapid, transient hyperpolarization followed by a gradual repolarization associated with increased synaptic noise.(ABSTRACT TRUNCATED AT 400 WORDS)

1. The patterns of membrane potential changes of phrenic motoneurons were compared during fictive vomiting, fictive coughing, and fictive swallowing in decerebrate, paralyzed cats. These fictive behaviors were identified by motor nerve discharge patterns similar to those recorded from the muscles of nonparalyzed animals. Phrenic motoneurons (n = 54) were identified by antidromic activation from the thoracic phrenic nerve. Intracellular recordings were obtained from 27 motoneurons during fictive vomiting, 40 during fictive coughing, and 27 during fictive swallowing. Sixteen motoneurons were recorded during both fictive coughing and fictive swallowing, eight during both fictive coughing and fictive vomiting, and two during both fictive vomiting and fictive swallowing. Seven motoneurons were studied during all three behaviors. 2. Fictive vomiting, typically evoked by electrical stimulation of abdominal vagal afferents, was characterized by a series of bursts of coactivation of phrenic and abdominal motor nerves, culminating in an expulsion phase in which abdominal discharge was prolonged both with respect to phrenic discharge and to abdominal discharge during the preceding retching phase. During fictive vomiting, phrenic motoneurons depolarized abruptly, and the amplitude of depolarization was significantly greater than during control inspirations. They then repolarized slowly throughout the phrenic burst, rapidly repolarizing at the end of each phrenic burst during retching and reaching a level similar to that observed during expiration. During the expulsion phase, the pattern was initially the same. However, after the cessation of phrenic discharge, the membrane potential repolarized slowly until the end of the abdominal burst, exhibiting greater synaptic noise than during expiration. One phrenic motoneuron, presumably innervating the periesophageal region of the diaphragm, received a strong hyperpolarization just before the onset of the emetic episode and fired for shorter periods during fictive vomiting than did other phrenic motoneurons.(ABSTRACT TRUNCATED AT 250 WORDS)

The quality of life and alimentary comfort of 17 patients with esophageal cancer who were disease free more than 3 years after an esophageal resection were evaluated by analyzing responses to a follow-up questionnaire. Fourteen patients had subtotal esophagectomy and gastric pull-up to the neck. Three patients underwent a total esophagopharyngolaryngectomy, the digestive continuity being restored by means of an isoperistaltic colon segment interposed between the base of the tongue and the stomach. Current body weight, when compared with that existing postoperatively, was increased in 13 patients and unchanged in four. The number of meals per day was an average of 2.8, but 12 patients took additional snacks between main meals (2.3 as a mean). The major long-term complaints were a sensation of early fullness during eating in 11 patients, dysphagia in three, diarrhea in two, cough-induced vomiting in two, and postprandial sweating in two. Ratings given by self-evaluation of current alimentary comfort in comparison with that predating the initial esophageal symptoms ranged from 3 of 10 to 10 of 10 (mean 7.1/10). Thirteen patients led active lives, seven at home and six employed outside the home. The present survey suggests that most disease-free patients may obtain a satisfactory quality of life after esophagectomy and gastric or colonic pull-up; long-term alimentary comfort is conditioned mainly by the small capacity of the esophageal substitute.

During the summer of 1990 deaths, occurred in racing camels (Camelus dromedarius) associated with a specific disease syndrome. Clinical signs included pyrexia, coughing, lachrymation, oedema of the throat and submandibular region and enlargement of submandibular lymph nodes. In terminal cases nervous signs were present and sometimes there was bloody diarrhoea and vomiting. Of 480 camels at least 70 animals were affected with the disease and about 40 died. Morbidity and mortality was greater in camels recently imported. Consistent necropsy findings were extensive petechial and ecchymotic haemorrhage beneath the epicardium, endocardium and visceral pleura and in the mediastinal lymph nodes, and haemorrhagic oedema of the pharyngeal and laryngeal areas. Haemorrhages occurred more variably in abdominal organs and on the omasal and abomasal mucosa. Bronchopneumonia, omasitis and abomasitis were observed on microscopic examination, together with liver and kidney lesions of presumed toxic origin. Fungal hyphae and, occasionally, the characteristic conidial morphology of Aspergillus fumigatus were seen in sections and direct smears from lesions in the respiratory and alimentary tracts. A fumigatus was cultured from trachea, bronchi, bronchioles, lung tissue, heart blood, omasum, abomasum, ileum and submandibular lymph nodes. Whether the role of Aspergillus in the overall syndrome is primary or secondary has not been established; no other potential aetiological agent has been identified.

Severe feeding troubles were recorded in five babies with long-gap esophageal atresia who underwent, between 1985 and 1990, a delayed primary anastomosis after spontaneous growth of their esophageal stumps. A comparison with 20 cases of direct esophageal anastomosis, operated on in the same period, was carried out by means of recorded esophagrams, pH monitoring and questionnaires charting the growth pattern and feeding habits of the patients. Bottle feeding, and, later on, the introduction of semi-solid foods was significantly retarded in the group of children with delayed primary anastomosis (labeled as group B) as well as height and weight parameters. Failure to complete feeds, dysphagia, vomiting, coughing, choking and recurrent respiratory symptoms were also significantly more common in this group than in the primary anastomosis group (labeled as group A) even in the absence of stricture. Variable degrees of disordered esophageal motility were present in all patients but pooling of the contrast medium, retrograde flow and delayed clearing of the esophagus were more frequent in group B. No patient was shown to have associated hiatal hernia. A 24 hour pH recording showed severe gastroesophageal reflux in 4 out of 13 cases of group A and in 3 out of 5 cases of group B. Clearing times were significantly delayed in all refluxing children. Our data suggest that the retarded start of oral feeding and swallowing coordination in patients with delayed primary anastomosis add further negative factors to their congenitally impaired esophageal motility, causing protracted dysphagia which represents a major problem for both family and hospital staff.

The aim of the randomized multicentre double-blind study was to establish whether nonionic contrast media differ in tolerability. The controlled comparison was conducted at 4 centres on a total of 798 patients with indication for i.v. DSA and computed tomography. The nonionic contrast media Iopamidol and Iopromide with an iodine content of 300 mg/ml each were studied. The osmolality of both contrast media is virtually identical. Both groups of patients were largely homogeneous in terms of demographic data and case history. The history of allergies was positive in 32.4% of the Iopamidol group and in 32.3% of the Iopromide group. The arithmetic mean of the doses administered to each patients was 148.3 and 149.3 ml, respectively. At all 4 centres there was a higher incidence of adverse events with Iopromide than with Iopamidol. The main differences with regard to pseudo-allergic reactions was the incidence of urticarial reactions, pruritus, nausea, vomiting and coughing. 89 of the 399 patients (22.3%) receiving Iopamidol and 120 of the 399 patients (30.1%) receiving Iopromide experienced pseudo-allergic reactions. The difference between both contrast media is statistically significant (p less than 0.05). There is a 95% certainty that less pseudo-allergic reactions will occur after an Iopamidol injection than after Iopromide. Possible explanations for the differences in tolerability between the two nonionic contrast media with identical osmolality are discussed.
