During eight weeks of a recent influenza epidemic 29 patients with ketoacidosis were admitted to the General Hospital, Birmingham. This was an exceptionally large number of cases. Of these, 14 had complained of a cough, nine had clinical evidence of respiratory infection, and four extensive bronchopneumonia. Hypokalaemia was present on admission in several instances and caused respiratory failure and death in three patients. Since the dangers of initial hypokalaemia are increased during the treatment of ketoacidosis, especially when sodium bicarbonate is used, serum potassium levels must be estimated initially and, if necessary, potassium chloride given intravenously at more frequent intervals than usual.

The red tide toxin produced by Ptychodiscus brevis ( PBTX ) may cause cough, sneezing, and asthma. Previous in vitro studies with isolated canine tracheal smooth muscle demonstrated that PBTX stimulates sodium channels of parasympathetic nerve endings and thus causes a contractile response. The present study investigated the mechanism of the PBTX effect on canine tracheal smooth muscle. Repeated exposure of the muscle strip to PBTX (final concentration 46 micrograms/ml) followed by washout of the toxin resulted in reestablishment of baseline tension but a failure of contraction on further addition of PBTX . However, veratridine and scorpion toxin (SCT), which are voltage-sensitive sodium channel activators, still induced contraction. Furthermore, the contraction caused by veratridine was enhanced by a high dose of PBTX , whereas contraction caused by SCT was not. Responses to veratridine and SCT as well as PBTX (previously reported) were blocked by tetrodotoxin (a sodium channel blocker), while acetylcholine responsiveness remained intact. These results indicate that PBTX receptors in parasympathetic nerves influence Na+ flux at the h gate, that these receptors differ from the veratridine and SCT receptors, and that the conformational change in the receptors induced by PBTX affects the tissue response to veratridine.

The inhalation of capsaicin for 1 min, delivered as an aerosol by nebulising solutions of capsaicin at concentrations of 2-65 mumol 1(-1), caused dose-dependent coughing in normal volunteers and subjects with mild asthma. Capsaicin did not cause a feeling of breathlessness, and had no effect on forced expiratory volume in 1 s (FEV1) measured at the 1st, 5th and 9th min after the challenge was completed. Coughing started within seconds of applying the face mask, continued throughout the minute of capsaicin inhalation, and stopped within seconds of the mask being removed. In any one subject the number of coughs was reproducible when repeated on the same day or after an interval of several days. Experiments using local anaesthesia applied to the buccal mucosa or larynx indicated that the cough was caused by the stimulation of capsaicin-sensitive nerve terminals situated in the larynx. Cough response was not altered by the prior inhalation of sodium cromoglycate.

In a group of patients with mild asthma the inhalation of mist derived from ultrasonically nebulised distilled water caused an increase in cough and a fall in FEV1. Double blind administration for five minutes of sodium cromoglycate (from an original solution containing 30 mg/ml) or atropine (2 mg/ml) by inhalation from a Minineb nebuliser, 30 minutes before the mist challenge, caused a significant reduction in the fall in FEV1 (p less than 0.05), but not in cough, by comparison with the protection afforded by placebo (saline). In a second study the fall in FEV1 caused by the inhalation of distilled water was not significantly different from that seen in response to hypotonic sodium chloride (1.7 g/l, 58 mmol/l), but both produced a significantly greater fall than did a similar mist containing sodium cromoglycate at an original concentration of 10 mg/ml (58 mmol/l). The results show that both atropine and sodium cromoglycate can block the fall in FEV1 due to mist and that protection by sodium cromoglycate is immediate. These results suggest that sodium cromoglycate blocks the nervous reflexes concerned in the response to mist, probably in the afferent limb of the reflex.

Two cases of bronchial asthma due to spiramycin in workers of a pharmaceutical factory are reported. The subjects complained of cough, breathlessness and symptoms of asthma at work when coming into contact with spiramycin's powder. The symptoms cleared when away from work for more than 3 or 4 days. Inhalation challenge tests by aerosolization of solutions of spiramycin reproduced asthmatic reactions dual in type in both patients, the immediate component of the response has not been previously described for this antibiotic. Furthermore, one of the patients developed an immediate asthmatic reaction also after inhalation of a solution of adipic acid, and additive to bind spiramycin and diminish its irritant action. The reaction was obtained at a non-irritant concentration of the acid, was reproducible and inhibited by previous administration of sodium cromoglycate: this finding and the failure to elicit the reaction in the other patient suggest a hypersensitivity reaction to this substance.

Ivermectin, given in a single subcutaneous dose of 200 micrograms/kg, was evaluated for its efficacy against Dirofilaria immitis microfilariae in a trial with naturally infected dogs. Sodium thiacetarsamide (2.2 mg/kg) was administered twice daily for 2 days to 2 groups of 10 dogs. Two weeks later, 1 group was treated with ivermectin, and the other group was given the vehicle. Microfilariae were not detected (by blood sample concentration techniques) in 90% of the dogs 21 days after they were treated with ivermectin. Microfilariae were not detected in samples of any dog at days 28 and 35. However, 1 dog (not the one positive at day 21) had a detectable microfilaria at day 42. One dog with pretreatment ascites, exercise-induced cough, and high microfilaremial count was anorectic and depressed 2 days after treatment with ivermectin; the clinical signs were resolved 4 days later.

A 77-year-old, nonalcoholic man was admitted to the Omiya Red Cross Hospital with the complaint of fever and delirium state of two days' duration. Two months prior to admission he had had cough and sputum. Chest X-ray revealed honey comb lungs. Cultures of sputum revealed mycobacterium tuberculosis after eight weeks incubation. He had no liver disease in his past history. The patient appeared cachetic. His vital signs were as follows; temperature 38 degrees C, blood pressure 132/68 mmHg, with a pulse rate of 84/min. He was delirium and excited. Findings of the cranial, motor and sensory nerve examination were normal. Initial laboratory studies showed a serum sodium value of 133 mEq/l, potassium 4.5 mEq/l, chloride 98 mEq/l; a serum GOT value of 51 units, GPT 36 units; a total protein content of 7.8 g/dl and ESR rate of 87 mm/hr. Six days after admission, the patients' consciousness level began to stupor and nuchal rigidity was appeared. Spinal fluid examination revealed opening pressure 270 mm H2O, cell counts 720 (N 712, L 8)/cumm, sugar 57 mg/dl and protein 170 mg/dl. Spinal fluid cultures were positive in mycobacterium tuberculosis after eight weeks incubation. Laboratory studies showed a serum sodium value of 114 mEq/l, potassium 4.4 mEq/l, chloride 86 mEq/l, a serum osmorality (SeOs) 225 mOsm/l and urine osmorality (UOs) 958 mOsm/l.(ABSTRACT TRUNCATED AT 250 WORDS)

Pulmonary infiltrates developed in three middle-aged women while receiving naproxen sodium. Weakness, fatigue, cough, low-grade fever, and eosinophilia in blood and/or sputum were common to all. All symptoms and findings resolved within a few days after discontinuing naproxen therapy in two cases and with use of corticosteroids (prednisone) in one case. A hypersensitivity reaction due to naproxen seemed to be the likely cause.

Within 15 minutes of terminating general anaesthesia, progressive recovery of consciousness, spontaneous ventilation and cough, and limb movements were assessed in 60 young children (age range 0-5 years, mean +/- SEM; 2.83 +/- 0.34; weight 13.86 +/- 0.41 kg). All patients were ASA physical status class I-III, received a standard intravenous induction (atropine 0.02 mg X kg-1, thiopental sodium 5 mg X kg-1, diazepam 0.2 mg X kg-1), were intubated with an orotracheal tube following the administration of metocurine, 0.4 mg X kg-1, and were maintained under general anaesthesia with nitrous oxide and oxygen in a 70:30 mixture administered by a T-piece circuit. They were ventilated mechanically to maintain normal blood-oxygen tension and normocarbia. The patients were assessed in three equal groups according to the anaesthetic supplement they received. Group I received intravenous infusions of morphine sulfate (loading dose 60 micrograms X kg-1 administered over 5 minutes followed by a continuous intravenous infusion of 2 micrograms X kg-1 X min-1. Patients in Groups II and III had 0.5 per cent halothane and 1.0 per cent isoflurane respectively added to the nitrous oxide/oxygen fresh gas mixture rather than morphine sulphate infusions. By the end of the study period, there was no significant difference in the degree of recovery between the morphine and the isoflurane groups but the patients in the halothane group had recovered to a lesser degree. Generally, the patients in the morphine group were awake but not crying, while those in the other two groups were less sedated.
