Abstract
Serial studies of leucocyte migration in vivo were carried out in 15 patients with Behçet's syndrome using a skin window technique. Where possible, patients with and without active disease were studied during and in the absence of treatment. In patients with active disease neutrophil migration was frequently greater than normal, particularly with respect to numbers of cells migrating. There was also an increased frequency of emigrating neutrophils with less or more nuclear lobes than normal. In three patients in whom function of skin window neutrophils was studied nitroblue tetrazolium reduction and phagocytosis and killing of Candida guilliermondiae were normal. The monocyte component of the skin window was more often reduced in patients than in normal controls. Corticosteroid treatment did not exert a major effect on leucocyte migration, though the doses involved were relatively small. Neutrophil abnormalities were common in patients and particularly those with active disease. These results suggest that neutrophil hyperactivity may have an important role in the pathogenesis of Behçet's syndrome.

Abstract
Patients with Behçet's syndrome have an increased risk of arterial and venous thrombosis, and abnormal platelet function has been implicated. Platelet function was studied in nine patients with Behçet's syndrome and in nine age- and sex-matched healthy volunteers. Platelet aggregation in response to ADP was measured, and the threshold concentration required to produce irreversible aggregation determined. Sensitivity of platelets to the inhibitory effect of prostacyclin was also determined. In addition, plasma levels of the platelet-specific proteins, beta-thromboglobulin and platelet factor 4, and stimulated platelet thromboxane B2 production, were measured. Platelets from patients with Behçet's syndrome showed normal aggregation in response to ADP, irrespective of disease activity. Platelet sensitivity to prostacyclin was, however, decreased compared with controls--with a mean prostacyclin ID50 of 5.5 +/- 1.3 ng ml-1 (mean +/- SEM) and 1.9 +/- 0.3 ng ml-1, respectively (P less than 0.01). This reduction in platelet sensitivity to prostacyclin was greatest in patients with the most active disease. These results suggest that Behçet's syndrome may be associated with altered platelet function, and this may have important consequences with regard to the increased risk of thrombosis associated with this condition.

Abstract
Pulmonary tuberculosis has rarely been recorded in patients with Behçet's syndrome, but to date no report has convincingly demonstrated any possible association between these two diseases. We describe three cases of pulmonary tuberculosis in patients with Behcet's syndrome and discuss the possible underlying mechanisms.

Abstract
We carried out a prospective, randomized, controlled trial to investigate the effect of a 3-month period of supplementary oral nutrition in 14 poorly nourished outpatients with COPD. Seven patients were randomized into Group 1 who received their normal diet during Months 1 to 3, a supplemented diet during Months 4 to 6, and their original normal diet during Months 7 to 9. The other 7 patients received their normal diet for the entire 9-month study period (Group 2). Seven well-nourished patients (Group 3) matched for age and severity of air-flow obstruction served as control subjects; they received their normal diet for the 9-month study period. Measurements of nutritional status, respiratory muscle and handgrip strength, sternomastoid muscle function (including frequency/force curves, maximal relaxation rate, and a fatigability test), lung function, arterial blood gas tensions, general well-being and breathlessness scores, and 6-min walking distances were carried out monthly in all patients. At the start of the study, the poorly nourished patients had lower mean daily calorie and protein intakes than did the well-nourished patients. The poorly nourished patients had lower respiratory muscle and handgrip strength, and abnormal contractility and increased fatigability of the sternomastoid muscle compared with those in the well-nourished patients. After 3 months of supplementary oral nutrition, there was a significant improvement in the nutritional status of Group 1 patients, as evidenced by an increase in body weight, triceps skinfold thickness, and midarm muscle circumference. Respiratory muscle and handgrip strength increased in parallel with nutritional status, although there were no significant changes in lung function or arterial blood gas tensions.(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
A syndrome consisting of a rigid spine and myopathy predominantly affecting proximal limb muscles has been previously described in children, and as with most neuromuscular disorders, the respiratory muscles appear to be affected only at an advanced stage in the disease. We describe an adult male with this syndrome who presented with ventilatory failure caused by severe respiratory muscle weakness and who demonstrated profound nocturnal arterial oxygen desaturation, particularly during rapid eye movement sleep. Treatment with negative pressure ventilation initially resulted in only modest improvements in symptoms, blood gas tensions, and nocturnal desaturation. The cause of this only partial improvement was upper airway obstruction provoked by the mode of ventilatory support used. After tracheostomy there was a dramatic and sustained improvement in symptoms and blood gas tensions and complete abolition of nocturnal arterial oxygen desaturation. This is the first report of an adult with the rigid spine syndrome presenting with ventilatory failure and cor pulmonale due to severe respiratory muscle weakness.

Abstract
In patients with severe respiratory disease, the work of breathing is increased and the respiratory muscles, particularly those of inspiration, may become fatigued. Hitherto, there has been little information on the incidence of respiratory muscle fatigue in acutely breathless patients. We studied 34 patients with severe respiratory disease on admission to hospital when they were most breathless, and then, if possible, 7 to 14 days later after recovery for evidence of sternomastoid muscle fatigue or increased fatigability. Frequency/force curves, numerically expressed as the 20:50 ratio, were carried out in all patients on admission. Three of the 34 patients had evidence of low frequency fatigue (i.e., greater than 15% reduction in 20:50 ratio) in the sternomastoid muscle on admission when first studied (mean +/- SEM 20:50 ratio, 56.3 +/- 1.2%; n = 3). The mean 20:50 ratio in the remaining 31 patients on admission was 75.7 +/- 1.6% (n = 31) compared with 77.8 +/- 1.4% (n = 25) when symptomatically better (p less than 0.05). The mean 20:50 ratio on admission was also significantly lower than the mean 20:50 ratio in a group of age- and sex-matched normal control subjects (i.e., 78.5 +/- 1.4%, n = 25; p less than 0.05). Twenty-five patients were studied completely both on admission and recovery, including a fatigability test that involved the performance of 50 fatiguing head lifts with measurements of the 20:50 ratio 10 and 60 min later. Sternomastoid muscle fatigability was significantly increased on admission when the patients were most breathless, compared with recovery when they were less breathless (p less than 0.001 at both 10 and 60 min).(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
A patient with Noonan's syndrome and fundal colobomata in both eyes is described. To our knowledge, this is the first report of the association of colobomata with Noonan's syndrome. Although the patient had poor sight since early childhood and dyspnea on exertion as a teenager, the diagnosis of Noonan's syndrome was not made until early adulthood. We hope this report will encourage recognition of this syndrome and its implications at an earlier stage.

Abstract
In a randomised controlled trial, twelve matched pairs of patients with chronic obstructive pulmonary disease received traditional Chinese acupuncture or placebo acupuncture. After three weeks' treatment the traditional-acupuncture group showed significantly greater benefit in terms of subjective scores of breathlessness and six-minute walking distance. Objective measures of lung function were unchanged in either group. Whether these differences are mediated by endogenous opiate and/or peptide release remains speculative.

Abstract
Factors precipitating nocturnal myocardial ischaemia were investigated in 10 patients with frequent daytime and nocturnal angina pectoris. Eight patients had fixed obstructive coronary artery disease or a low exercise threshold or both before the onset of ischaemia. Two patients had variant angina with normal coronary arteries and negative exercise tests. During sleep the electrocardiogram, electroencephalogram, electro-oculogram, electromyogram, chest wall movements, nasal airflow, and oxygen saturation were continuously measured. Forty two episodes of transient ST segment depression were recorded in the eight patients with coronary artery disease and 26 episodes of ST segment depression and elevation in the two patients with variant angina and normal coronary arteries. All episodes of ST segment depression in the former group of patients were preceded by an increase in heart rate as a result of arousal and lightening of sleep, bodily movements, rapid eye movement sleep, or sleep apnoea (one episode). In contrast, in the variant angina group no increase in heart rate, arousal, or apnoea preceded 23 of the 26 episodes of ST segment change. Thus increase in myocardial oxygen demand was important in precipitating nocturnal angina in patients with coronary artery disease and reduced coronary reserve. In the patients with coronary spasm these factors did not often precede the onset of nocturnal myocardial ischaemia.

Abstract
We describe a patient with myasthenia gravis, systemic lupus erythematosus, and angioedema associated with heterozygous complement factor 2 (C2) deficiency. The significance of this association is controversial, though the association of C2 deficiency with certain histocompatibility antigens suggests possible linkage to immune response genes. To our knowledge this is the first report of heterozygous C2 deficiency in association with this combination of 'autoimmune' disorders, and we discuss the aetiological implications.

Abstract
Two brothers with Fabry's disease presenting with palpitations were found to have intermittent supraventricular tachycardias. Their electrocardiograms, when symptom-free, revealed short PR intervals consistent with ventricular pre-excitation. Treatment of one of the brothers with verapamil resulted in improvement of the palpitations and reduction in frequency of the tachycardia. Recurrent supraventricular tachycardia associated with ventricular pre-excitation has not previously been described in Fabry's disease. Evidence suggests that this complication may be due to glycolipid deposition in the conducting system around the atrioventricular node.

Abstract
It is not certain to what extent low frequency fatigue affects the performance of a muscle. We studied the endurance capacity of the sternomastoid muscle to undergo repetitive isometric neck flexion contractions for 2 s every 4 s at 35% of its maximal voluntary contraction force (MVC) in 5 normal subjects starting with different levels of fatigue. The endurance time, the duration the subjects were able to achieve the target force before exhaustion, was measured in each subject on 3 occasions: Study 1: in the fresh state, with a normal frequency/force curve and 20:50 ratio (ratio of force response at 20 Hz to that at 50 Hz) before the start of the endurance exercise; Study 2: with a moderately reduced 20:50 ratio before the start of endurance exercise (mean +/- SEM reduction in 20:50 ratio 11.4 +/- 0.8%); Study 3: with a substantially reduced 20:50 ratio before the start of the endurance exercise (29.2 +/- 3.7%). These reductions in 20:50 ratio were produced by the subjects performing 150 isometric neck flexion contractions at 50% of their MVC, followed by a period of rest to allow the 20:50 ratio to recover to approximately 10% of the starting value in Study 2, and to within 20 to 40% of the starting value in Study 3. Endurance exercise was then carried out.(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
Five patients with Behçet's syndrome presenting with haemoptysis and recurrent radiographic opacities are reported, with a review of 23 similar cases. All 28 cases conformed to a definite clinical pattern with haemoptysis, usually accompanied by pyrexia, chest pain and dyspnoea, being the major feature. Typically pulmonary disease was associated with active disease at other sites, although the patients often only complained of haemoptysis. Patients with Behçet's syndrome and haemoptysis, compared to those without haemoptysis, showed a marked male predominance, with thrombophlebitis and deep vein thrombosis being more common. Rarely pulmonary disease occurred in the absence of one or other of the so called 'major' criteria on which the diagnosis of Behçet's syndrome is usually made, as was so for four of our patients who did not have ocular disease. Immunopathological evidence suggests that the underlying pathogenesis is a pulmonary vasculitis which may result in arterial and venous thromboses, pulmonary infarction, pulmonary haemorrhage and pulmonary arterial aneurysm formation. A role for immune complexes in the pathogenesis of pulmonary disease in Behçet's syndrome is suggested by the finding of circulating immune complexes in association with active pulmonary disease. Corticosteroids were initially helpful in treating active disease in the lungs, and at other sites, in most of the patients in whom they were tried, including our five patients, but serious haemoptysis occasionally recurred, despite further treatment. Four of our patients were initially treated with anticoagulants for a presumed diagnosis of pulmonary embolism, but continued to have haemoptysis. One of these patients subsequently died following massive haemoptysis, despite good anticoagulant control. The haemoptysis in most of the 28 cases was notable for its severity, and in at least 11 (39.3 per cent), pulmonary haemorrhage was the probable cause of death. All deaths due to haemoptysis occurred within six years of the first episode. Whilst pulmonary disease with haemoptysis is infrequent, it carries a very serious prognosis and for this reason correct diagnosis and appropriate treatment is imperative. Pulmonary disease with haemoptysis should be included as one of the so called 'minor' criteria in the diagnosis of Behçet's syndrome.

Abstract
The effect of intravenous aminophylline on the contractility of the sternomastoid muscle was measured in the fresh state and after the induction of significant fatigue in five normal subjects. Fatigue was produced by repetitive isometric neck flexion, for two seconds every four seconds at 70% of the maximum voluntary contractile force, continued until exhaustion. Each subject performed three experiments, one to two weeks apart, in random order. In experiment 1 fatiguing exercise and recovery were completed without aminophylline; in experiment 2 intravenous aminophylline was started 30 minutes before exercise and continued throughout the 60 minute recovery period; and in experiment 3 intravenous aminophylline was started immediately after the end of exercise. Aminophylline did not influence the frequency-force relationships, relaxation rate, or maximum voluntary contractile force in the fresh muscle. After fatiguing exercise there was a relatively selective reduction in force response to stimulation frequencies of less than 30 Hz, with little alteration in forces at higher frequencies--that is, low frequency fatigue--and this effect was present for the entire one hour study period. Aminophylline given before or immediately after fatigue did not influence the recovery of either low frequency fatigue or maximum voluntary contractile force. Aminophylline at therapeutic concentrations had no significant effect on the contractility or fatiguability of the normal human sternomastoid muscle.

Abstract
In 223 patients admitted to hospital with cystic fibrosis mycobacteria were found in the sputa of seven. All of these cases were identified over a six year period after the introduction of routine examination and culture of sputum for acid fast bacilli in patients with cystic fibrosis. The organisms isolated were Mycobacterium tuberculosis in three patients, M chelonei in one, M fortuitum in one, and unidentified mycobacteria in two. The diagnosis was not suspected on clinical grounds in any of the cases; in one patient, however, night sweats were a prominent feature before diagnosis. In four of the patients direct sputum smear examination did not reveal the organism, which was grown subsequently in culture. An unusual phenomenon of liquefaction of the Lowenstein-Jensen culture medium was encountered in five of the seven patients described, which in one case made identification and sensitivity testing of the organism impossible. This phenomenon has been observed in sputum cultures from other patients with cystic fibrosis but not in other pulmonary diseases. Immunological studies performed in three of the patients showed normal numbers of peripheral blood T and B lymphocyte in all three; in vitro lymphocyte transformation to tuberculin PPD was, however, reduced in the patient with extensive M fortuitum infection, which proved fatal. Mycobacteria may be present in the sputa of patients with cystic fibrosis more often than previously recognised and therefore sputum examination and culture for mycobacteria should be performed periodically in these patients.

Abstract
From January to April 1980 46 young adults with cystic fibrosis were studied for evidence of infection with a wide variety of microorganisms, including viruses and Legionella pneumophila. Two groups of patients were investigated: a "deteriorated" group of 24 patients who had experienced an increase in lower respiratory tract symptoms and fall in lung function values in the course of one month before the start of the study and a "stable" group of 22 patients with no such deterioration. All serological tests were repeated at one month and then one year after the beginning of the study. A fourfold rise in titres of antibodies to various viruses, Mycoplasma pneumoniae, and Coxiella burnetii was obtained in seven (29%) of the deteriorated group but in only one (4.5%) of the stable group (p less than 0.05). One other patient showed a fourfold rise in L pneumophila antibody titre (on the basis of the indirect fluorescent antibody test), which was accompanied by a respiratory illness consistent with legionnaires' disease. Eight of the 46 patients (17.4%) had demonstrable titres of antibody against L pneumophila (1/32 or above).

Abstract
Specific antibody production and the proliferative response of peripheral blood lymphocytes (PBLs) to a variety of viruses, including herpes simplex virus-type-1 (HSV-1) and varicella zoster (VZ), were studied in 7 patients with Behçet's syndrome. None of the patients produced an antibody response against HSV-1 or VZ. Furthermore, none of the patients showed a proliferative response to VZ, and three of them also failed to mount a response to HSV-1. These results suggest that the PBLs of patients with Behçet's syndrome make an inappropriately poor antibody and proliferative response when stimulated by HSV-1 and VZ.

Abstract
The blocking effects of inhaled beclomethasone dipropionate (BDP) and fluocortin butyl ester (FCB) on the immediate and late asthmatic reactions induced by inhaled allergen were studied in two trials. In the first, a double-blind cross-over trial compared BDP (800 micrograms daily as powder) with FCB 8 mg daily (1:20 by wt.-Formulation 1). The second trial was identical in design and compared FCB 8 mg daily (1:20) with FCB 8 mg daily as Formulation 2 (1:40). Known BDP, 400 micrograms daily by pressurized aerosol was studied at the end of the second trial. Allergen provocation was performed before and after 7 days treatment with each drug, with a 2-week interval between each drug. Overall, a blocking index for the immediate reaction of greater than 50% was obtained in ten of twenty patients (50%) using BDP, and five of twenty-one (25%) using FCB (P less than 0.01). The late reaction was blocked in nine of eleven (82%) instances on BDP, and four of fourteen (33%) on FCB. Contrary to earlier reports, inhaled corticosteroid agents used for several days prior to bronchial challenge, were found to block both the immediate as well as the late reaction in many individuals.
