Quinton-Scribner shunts have been used as a reliable access to the blood-stream in 56 patients treated with intermittent hemodialysis in the years 1965-71. The mean age of 29 men and 27 women was 39 years. Two hundred and thirty-two cannulae showed a mean survival time of 11.2 months for 103 arterial cannulae and 9.0 months for 129 venous cannulae. 700 shunt clotting episodes occurred during 1157 patient months, i.e. 0.6 clotting episode/month. In 350 episodes where saline flushing could not remove the clot, the effect of treatment with streptokinase was considered evident in 79.7%. Shunt cannula infection was a common complication while aseptic cutaneous necrosis and bleeding from the cannulated vessel were seen less frequently. Both severe and less harmful bleeding episodes were seen as a complication of dicumarol therapy. The number of complications to streptokinase treatments was low. The advantages and disadvantages of the Quinton-Scribner shunt for hemodialysis are discussed.

Treatment was interrupted abruptly in 6 hypertensive patients receiving clonidine 0-45-5-4 mg daily. Blood-pressure rose to pretreatment levels within 24-48 h of withdrawal and was accompanied by insomnia, headache, flushing, sweating, and apprehension. These symptoms began 18-20 h after the last dose of clonidine. Plasma-noradrenaline levels and urinary catecholamine excretion increased 24-72 h after withdrawal of clonidine. The subjective symptoms were most prominent in patients on higher doses (greater than 1 mg/day) and in those who had previously been receiving treatment with other antihypertensive drugs. One patient on a very low daily dose (0-15 mg) of clonidine had no symptoms and no significant changes in blood-pressure or catecholamine production after drug withdrawal.

Plasma levels of oestrone and oestradiol-17beta were determined at 20 or 30 minute intervals for up to 24 hours in 26 postmenopausal or ovariectomised women of similar age, weight, and number of years since menopause or operation. Results in women with both superficial dyspareunia and flushes were compared with those in women with flushes only, and with those in symptomless women. Women with superficial dyspareunia had significantly lower mean concentrations of plasma-oestradiol, but not of oestrone, than symptomless women. Flushes were not related to plasma-oestrogen. The implications of these findings in relation to the optimum dose of oestrogen for treating climacteric symptoms are discussed.

Non-insulin-dependent diabetes is associated with facial flushing after alcohol in patients on chlorpropamide (chlorpropamide alcohol flushing, C.P.A.F.) especially when there is a family history of diabetes. C.P.A.F. in three subjects (two diabetics, one non-diabetic) was blocked by the specific opiate antagonist naloxone. In nine subjects (six diabetics) C.P.A.F. was reproduced by the enkephalin analogue with opiate-like activity [D-Ala2, MePhe4, Met (O)-ol] enkephalin (DAMME). C.P.A.F. thus may be due to increased sensitivity to endogenous opiates. DAMME and other substances with opiate-like activity, such as morphine and beta-endorphin, affect carbohydrate metabolism and insulin secretion. Increased sensitivity to endogenous opiates such as enkephalin may thus give rise to non-insulin-dependent diabetes associated with C.P.A.F.

"Mason-type" diabetics (mild diabetes which is dominantly inherited) are relatively free of retinopathy. Alcohol almost invariably causes facial flushing in these patients when they are given chlorpropamide (chlorpropamide alcohol flush, C.P.A.F.). 291 non-insulin-dependent diabetics were examined to see whether there was a difference in frequency of retinopathy between C.P.A.F. positive and negative cases who were of comparable age and duration of diabetes. Retinopathy was commoner and often severe in CPAF negative patients. Blindness from retinopathy was almost confined to C.P.A.F.-negative cases. Lens opacities, on the other hand, were equally common in both groups. Since C.P.A.F. is an inherited trait, retinopathy in non-insulin-dependent diabetics is to a considerable extent, although not entirely, determined by genetic factors.

Paroxystic vasomotor skin manifestations are provoked by various etiologies. Widespread or generalized vasomotor skin manifestations may be induced by a physiological reaction (emotinal flushing), by a drug (vasodilator drugs, antabuse, antidiabetic, sulfonamides), by a discharge of histamine (urticaria, mastocytosis) or by an hypersecretion of serotonin (dumping-syndrome, carcinoid syndrome). They may be caused by an endocrinopathy (menopause, hyperthyroidism, hypoglycaemia, medullary thyroid carcinoma, pheochromocytoma, endocrine pancreas, carcinoma). More rarely vasomotor troubles happen in homocystinuria, inhalation of a toxic (trichlorethylen, calcic cyanamid) and exceptionally in some immunohaematologic diseases. Main localized vasomotor skin manifestations observed are dermographism, facial flushing (Sluder's syndrome, cluster headaches, Frey's syndrome, Riley-Day's syndrome) and acral syndromes (Raynaud's phenomenon, erythromelalgia).

An H1-receptor blocking antihistamine, clemastine, taken before aspirin gave complete or partial protection against flushing, rhinorrhea, cough, and headache in ten asthmatic patients with idiosyncrasy to aspirin. In five of the ten patients aspirin-precipitated bronchoconstriction was also reduced or prevented after pretreatment with clemastine. Thus histamine appears to play a part in the production of most non-respiratory symptoms occurring after aspirin ingestion in intolerant patients with asthma. Bronchial reactions might depend partly on histamine and partly on the action of other spasmogens. It is suggested that inhibition of prostaglandins of the E series by aspirin-like drugs plays a crucial part in the release of histamine from tissue stores in aspirin-sensitive asthmatic patients. Clemastine might be of use in the treatment of acute reactions to aspirin.

Reflux of embolic material during therapeutic transcatheter embolization is a potential complication which can result in occlusion of distal vascular beds. The conditions under which reflux was demonstrated in laboratory animals include (1) low flow states, (2) overvigorous flushing, (3) selective contrast injections, and (4) placement of embolic material too proximally. Balloon occlusion of the orifice of the vessel undergoing embolization protects against reflux and allows more homogenous embolization. Because of experience gained in the laboratory, therapeutic transcatheter embolization is now performed in patients with balloon catheter protection. Preliminary clinical experience is described.

The present study shows that in the presence of 600 nm light, sulfide acts as a specific inhibitor of photosynthetic electron transport between water and Photosystem II in the cyanobacteria Aphanothece halophytica and Synechococcus 6311 as well as in tobacco chloroplasts. In the presence of 600 nm light sulfied affects the fast fluorescence transients as does a low concentration (10 mM) of hydroxylamine; the fluorescence yield decreases in the presence of either chemical and can be restored by the addition of 3-(3,4-dichlorophenyl)-1,1-dimethylurea. In chloroplasts, however, NH2OH, an electron donor at high concentrations (40 mM), relieves the sulfide effect. In the dark, sulfide affects the cyanobacterial fluorescence transients through decrease of oxygen tension. The fluorescence yield increases in a similar pattern to that observed under nitrogen flushing. Upon omission of sulfide in A. halophytica, the characteristic aerobic fluorescence transients return, consistent with the ease of alternation between oxygenic and sulfide-dependent anoxygenic photosynthesis in many cyanobacteria.

A double-blind crossover study of the efficacy of disodium cromoglycate given by mouth to control the cutaneous, gastrointestinal and central-nervous-system manifestations of systemic mastocytosis was carried out in five patients for periods of eight to 32 months. In 15 of 18 trials, disodium cromoglycate produced marked amelioration of the clinical manifestations of pruritus, whealing, flushing, diarrhea, abdominal pain and disorders of cognitive function. By contrast, in all 19 trials with placebo, there was no improvement in these symptoms and signs. Histaminuria and peripheral-blood eosinophilia were unrelated to disease activity and were unaffected by drug therapy. Although it is poorly absorbed after administration by mouth, disodium cromoglycate is of clinical benefit to patients with systemic mastocytosis.
