To investigate the application of a cough-creating thrust for the removal of airway-obstructing foreign material, the thrust was applied to six adult male anesthetized volunteers at the waist, at the low chest level, and at the midchest level, with the subjects in both the horizontal-lateral and the sitting positions. Air volume, peak air flow rate, and airway measurements were made. Both the low chest and midchest thrusts produced significantly better results than did the abdominal thrust. There were no side effects attributable to the thrusts. The ease of application and consistently better level of results indicate that the chest thrust is the technique of choice. The application of the chest thrust should be integrated into the concepts of basic life-support and cardiopulmonary resuscitation.

A 50-year-old Japanese female with choriocarcinoma showed three unusual features: the primary tumor developed in the vagina ectopically without uterine lesion; the first symptoms of atypical vaginal bleeding and coughing occurred 23 years after the last pregnancy; and the tumor appeared during postmenopause. The possible mechanisms for the ectopic location and latency are discussed.

The eyes of an 81-year-old man were obtained three and ten days after intracapsular extractions had been made through limbal incisions under limbal-based flaps of conjunctiva and Tenon's capsule. The wounds were closed with 7-0 chromic collagen. Before death from bronchopneumonia, the patient developed bilateral filtrations in association with violent coughing spells. In both specimens, the healing processes of the conjunctiva and Tenon's capsule were advanced, confining the escaping aqueous humor to the subepithelial tissues of the flap. In contrast, the stromal wounds were still inert in accordance with our earlier observations that these wounds are precariously weak during the first two weeks after surgery. In cataract surgery, flaps including both conjunctiva and Tenon's capsule should be prepared and closed to support the slower healing stromal wound. Prevention of filtrations is not a simple matter of using many sutures. This patient's eyes demonstrated that improperly placed or too tightly tied sutures may be directly responsible for leaking wounds.

The safety of outpatient surgery depends mainly on patient selection, the type of operation, and the anesthetic technique. Subjects of this study were 500 women who as outpatients underwent tubal electrocoagulation through a laparoscope. After an interval of 1 week to 4 months postoperatively, each was sent a questionnaire regarding postanesthetic complications. The questionnaire was returned by 418 patients (83.6%). Several anesthetic agents had been used. Premedication was given only to very nervous patients (18%). Atropine .4 mg was given to all just before the operation. The trachae of all patients were untubated after a dose of succinylcholine and in 60% of cases 3-6 mg of D-tubocurare. There were no immediate anesthetic complications. Most patients were discharged within 3 hours. Postanesthetic complications were common. Muscle pains occurred in 45%, many lasting 2-5 days. Sore throat followed in 28.2% but was usually mild. Headache, nausea, vomiting, cough, and sputum were noted in 8-17%. A mild dizziness was sometimes a complaint. Inability to concentrate was experienced by 30% of patients for over 2 days. In 32.9 %, return to usual work took up to 48 hours; in 57.9%, it was 2-5 days w hile the others required over 5 days. 81% of the patients reported that they would accept the procedure again, while 16.7% would refuse. Return to preoperative mental status usually took several days and in a few over 5 days. Too early use of alcoholic beverages or driving an automob ile were warned against. Most patients considered that the advantage of having the operation as outpatients made up for the discomforts.

The localization of the central cough mechanism was studied by electrically stimulating the lower brainstem in cats lightly anesthetized with pentobarbital sodium or in unanesthetized midcollicular decerebrate preparations. Cough responses were recorded with the aid of a microphone. The cough responsive region was concentrated in an area dorsomedial to the trigeminal tract and nucleus. The sites of action of antitussive agents (dextromethorphan, codeine, clonazepam, diazepam and caramiphen) were studied on the centrally induced cough responses. Each of these drugs was administered intravenously to determine the dorsal levels for cough suppression. In other series, the threshold dose via the intravertebral route was determined first. Because the agent necessary to prevent cough via this route was so small in amount, recovery usually occurred in 20 to 90 minutes. Then the same agent was given intravenously in an attempt to obtain an effective dose which was close to the minimum dose for blocking the cough. The mean effective doses of these agents to abolish the cough via the vertebral artery were only about 1/20 of those required via intravenous injection. The findings suggest that these agents act centrally to suppress the cough responses. Clonazepam was found to be the most potent antitussive among these agents, the mean effective dose being about 1/35 of that of codeine. The antitussive potency of benzodiazepines is not well correlated with their muscle relaxant activity. For instance, clonazepam and diazepam have the same potency in depressing polysynaptic spinal reflexes, whereas the former is 6 times more potent than diazepam as an antitussive. This finding indicates that clonazepam has a high specificity as an antitussive.

Subjects residing in the warm, dry climate of Tucson, Arizona showed the same relationship of productive cough to smoking as noted elsewhere, but they less regularly reported seasonal or diurnal exacerbations of their symptoms and they less regularly reported phlegm production along with chronic cough. In this locale, even nonchronic dry cough was associated with an increased frequency of other respiratory symptoms and of ventilatory impairment. In comparing characteristics of subjects with a clinical diagnosis of chronic bronchitis with characteristics of subjects who had only questionnaire-detected chronic productive cough, it was found that smoking habits were more closely related to the presence of chronic cough than to the clinical diagnosis. The clinical diagnosis was associated with other features, such as wheezing, at least as often as with productive cough. This was especially true in children, in whom a suprisingly high prevalence of both chronic cough and clinically confirmed chronic bronchitis was noted. These observations led to questions concerning the appropriateness of using a common clinical term such as chronic bronchitis to describe subjects whose only known abnormality is an affirmative answer to a direct question concerning phlegm production.

We assessed the prevalence of respiratory symptoms and loose cough in 622 school-age children from an urban town in Connecticut. A higher prevalence of chronic symptoms was reported by black children, but the prevalence of recent symptoms and of loose cough in black children was similar to that in white children. The relationship between prevalence of recent symptoms and loose cough suggests that the observed racial differences in prevalence of chronic symptoms were unlikely to be due to racial differences in responses to a respiratory symptom questionnaire.

1. In forty non-smoking healthy subjects and seventy-two patients with left heart diseases measurements were made of the volume expired in the first second of a forced expiration (FEV1) and the total volume expired in a forced expiration (FVC) before and after inhalation of salbutamol. Before and after salbutamol the healthy subjects and patients also inhaled maximally an inspirate, the first part of which contained 133Xe and, during controlled expiration, the radioactivity of the expirate was measured and plotted against its volume. the resulting curves were divided into phases of different slope by eye, the point at which phase 3 changed to phase 4 being nominated the closing volume. 2. In forty non-smoking healthy subjects inhalation of salbutamol was followed by significant increase in FEV1 but FVC and closing volume did not change. 3. Change in posture from seated erect to supine in thirty of these healthy subjects was accompanied by significant reduction in FEV1 and FVC and as closing volume was not significantly different in the two positions the ratio closing volume/vital capacity was increased with recumbency. 4. In seventy-two patients with left heart diseases without a history of cough or wheeze, FEV1, FVC, closing volume and the ratio closing volume/vital capacity were significantly different from values in the healthy subjects. There was no significant difference between non-smokers and ex-smokers amongst the patients. 5. Significant increase in FEV1, FVC and reduction in closing volume and the ratio closing volume/vital capacity followed inhalation of salbutamol in patients with heart diseases but the values remained significantly different from those recorded in the healthy subjects. 6. In twenty patients with heart diseases, FEV1 and FVC were reduced by change in posture from seated erect to supine but the ratio closing volume/vital capacity and the regression with age of this ratio were not significantly changed by change in position. 7. In patients with heart diseases the ratio closing volume/vital capacity was significantly correlated with severity of breathlessness and length of symptom-history but not with left ventricular end-diastolic or pulmonary vein wedge pressures.

This is the ninth recorded case of the rare complication of unilateral pulmonary oedema following drainage of a pneumothorax. The complication should be anticipated if the pneumothorax has been present for longer than 3 days, or if coughing and shock develop after insertion of the drain. Radiological confirmation and prompt treatment are necessary. The literature is reviewed.

A 21-year-old woman was admitted to our hospital because of high fever, cough, and headache. Other clinical manifestations included hepatosplenomegaly, anemia, leukopenia, and mild liver dysfunction. As she had been diagnosed to have systemic lupus erythematosus (SLE) previously, we first suspected that this disease had become exacerbated. However, the titers of anti-EB virus (VCA-IgG) and some other viruses were high on admission, and hemophagocytosis by macrophages was observed on bone marrow examination. Therefore, she was diagnosed to have virus-associated hemophagocytic syndrome (VAHS). Prednisolone therapy was then initiated, but the patient responded poorly. We next tried gamma globulin, and the clinical findings and laboratory data were improved. Our patient showed a very favourable clinical course following gamma globulin therapy, suggesting that steroid and gamma globulin should be considered as a treatment even in the early stages of this syndrome in adults.
