An unusual complication of benign esophagobronchial fistula, secondary to a ruptured esophageal traction diverticulum, is reported and illustrated. The patient presented with a history of chronic, recurrent bronchitis and intermittent episodes of paroxysmal attacks of coughing and strangling on the ingestion of fluids (Ono's sign). A review of the literature with emphasis on the occurrence, pathogenesis, radiographic features, and clinical implications of esophageal traction diverticula is presented.

Squirrel monkeys were inoculated by the intratracheal inoculation of 700 Klebsiella pneumoniae organisms and developed lobar pneumonia in about 24 h. Characteristic clinical findings were fever, anorexia, and coughing. Laboratory findings included leukocytosis or leukopenia (with the latter more prominent in ultimately fatal infections), bacteremia, and shedding of bacteria into the pharynx. Infected monkeys showed increased plasma lysozyme activity as well as increased plasma ceruloplasmin, haptoglobin and alpha1-antitrypsin. The mortality rate was 60%, and the mean time of death was 50.5 h. Pathologically, the disease spread by means of Kohn's pores and other pathways that generally did not involve airways as a means of dissemination until about 30 h. Squirrel monkeys seem to be better models for human respiratory K. pneumoniae infection than rats or mice.

In 16 baboons, reproducible bronchograms could be achieved by inhalation of 400--800 mg of powdered calcium ioglycamic acid. Anesthesia, tracheal intubation, or premedication were not necessary. In patients and volunteers, the inhalation of the contrast medium dust caused strong cough. Local anesthesia allowed inhalation for about 10 minutes, which resulted in successful demonstration of the pharynx, larynx, and trachea with bifurcation. Lobular and segmental bronchi were demonstrated only after a longer inhalation time. The contrast medium was completely eliminated and did not cause any recognizable adverse reaction. Nonspecific inflammatory reaction of the bronchial mucosa was seen microscopically in baboons.

A number of newly-developed vaccines are available nowadays, whilst others, which are well-established, have been improved. The collection of epidemiological data, however, is equally important in assessing and providing insight into prophylactic measures. The beneficial effects and risks of vaccination may be calculated by special formulae. Changes in the effect of vaccines can be detected by constant reevaluation of the epidemiological situation by means of these formulae. Another possibility lies in the calculation of the borderline number of complications of a certain disease when the risks of the sequelae of the disease or of the vaccination are about equal. Examples of valuable and recommendable vaccinations are vaccination against measles, poliomyelitis, tetanus and tick-borne encephalitis. A follow-up of the case mortality of whooping-cough in Austria over the past 15 years and a consideration of the fatal complications of vacinnation, as quoted by Ehrengut, reveals that the risks of the disease balanced the risks of vaccination with usual vaccines, already in 1971 (1976 with WHO data). A beneficial effect of BCG vaccination is still present, but the influence on mortality figures is very slight only. However, the benefit of BCG may lie in the prevention of deaths from leukaemia observed by some authors. Paraspecific effects of some vaccinations are mentioned. Finally, cost-benefit calculations for Austria are presented in the case of vaccination against measles and mumps, which appear to be highly recommendable, not only from the medical, but also the economic point of view.

Reproducible immediate-type respiratory responses were evoked in conscious monkeys, sensitive to inhaled Ascaris suum, for periods up to 18 months. These responses were characterized by decreases in tidal volume and increases in breathing rate that persisted for about 40 min. Maximum changes were seen 3--5 min after exposure to the aerosolized antigen and were often accompanied by coughing and increased movement of the animals within the plethysmograph used for monitoring their ventilatory changes. Significant inhibition of the Ascaris-induced respiratory changes were seen in animals treated with either isoproterenol or cromolyn sodium. However, the latter agent was not effective in reversing histamine-induced ventilatory changes. The conscious monkey appears to be a suitable animal for evaluating potential antiallergic drugs.

An epidemic of influenza B began in January, 1977, in two rural parishes in northeastern Louisiana and quickly spread to involve 29% of their population with clinical influenza. This epidemic was investigated using a standard questionnaire and a random sample of 4.2% of the population. The clinical illness was typical of influenza, with predominant fever, cough, malaise and headache. Gastrointestinal symptoms were part of the clinical syndrome. Rhinitis and diarrhea were significantly more common in children aged five years or less. Clinical attack rates increased with larger household size. The youngest age groups had clinical attack rate of 40--55%, but the elderly had very low attack rates. The direct cost of influenza-like illness during the epidemic averaged almost $30.00 per case. Knowledge of the cost of influenza-like illness and age-specific attack rates should be useful in planning future control efforts for influenza B.

The authors studied the elicitability of the expiration and aspiration reflex and of the respiratory reaction from the tracheobronchial area in 131 anaesthetized rats (aged 1-15 days, adult and biologically old). They found that the expiration reflex could be elicited, in the rat, from the first day of life, at a time when other respiratory reflexes were not yet stable. In young rats, the expiration reflex was often followed by a cough reaction which was absent in adult animals. The findings indicate that the expiration reflex is one of the most important respiratory reflexes of the early postnatal period in the rat, because the aspiration reflex and the respiratory reaction from the bronchi were not stable until the 15th day of life. In biological old rats, the expiration reflex is less frequently elicited and its intensity attains about half the value found in adult animals. The aspiration reflex and the respiratory reaction from the bronchi are likewise less readily elicited than in adult animals, but when the intensity of their maximum expiratory effort is increased, it is far greater.

During tomography of the major air passages, the radiologist is occasionally surprised by an appearance which is indistinguishable from an intraluminal tumour. In addition to a genuine tumour, one must then consider the possibility of a mucus plug. One can distinguish between these possibilities by repeating the appropriate cuts after the patient has coughed several times. It will then be found that the position or appearance of the mucus plug will have altered, or that it will have disappeared completely. This phenomenom occurs primarily in older patients, or patients unable to cough. We report ten such cases.

Two patients had diffuse, reversible pulmonary injury possibly owing to gold sodium thiomalate treatment: a 32-year-old woman with chronic inflammatory arthritis compatible with seronegative rheumatoid arthritis and a 32-year-old man with shoulder arthralgia. The patients had received 420 mg and 325 mg of gold sodium thiomalate, respectively. Cough and dyspnea began in the seventh and fifth weeks of therapy, respectively. In both patients x-ray study showed bilateral pulmonary infiltrates, with no evidence of pleural disease. The woman had no other manifestations of hypersensitivity to gold. The man had exfoliative dermatitis fever and anemia. Lung biopsies from both patients revealed lymphocytes and plasma cells infiltrating the alveolar septa and interstitial fibrosis. The woman improved slowly during four months after discontinuation of therapy. Pulmonary symptoms recurred after additional gold therapy, and again resolved when gold was discontinued. The man, treated with prednisone, showed prompt remission and remains will without medication.

Singers and actors offer special problems to the laryngologist as far as their personality is concerned as the individual intensity of their vocal usage. A successful therapeutical approach requires that the doctor is able to involve himself into the physical and psychic conditions of an artistic usage of the voice; he also should be as well open to singing as to music in general. Knowledge in pathophysiology of larynx and voice, experiences in phoniatry and psychological interests will enable the larngologist to solve such medical problems which occur when working on diseases of the voice of singers and actors. Based on these few remarks, the report deals with the following short chapters: doctor and singer, the most frequent causes of vocal disorders, the "dry throat' of the singer, coughing out of custom, vocal nodules, the prevention of damages of the voice, the singer's voice under endocrine influences, possible damages of the voice in connection with operations and - the actor with an ill voice.
