854 hydroxycorticosteroids after corticotrophin stimulation, 6 and the measurement of plasma-steroid levels.’ Robson and Kilborn 8 have described 34 patients with con- tinuous asthma who had received no treatment with corticosteroids or corticotrophin. Like earlier workers, they found that the urinary steroid metabolites were mostly in the normal range. They also found that, al- though the resting production of cortisol by these patients was normal, the production of cortisol after corticotrophin stimulation was below normal in about two-thirds of the asthmatics studied. A functional abnormality of the adrenals has been postulated on this evidence, but the problem of comparing one group of patients with " normals " is nowhere greater than in assessing adrenal function. A relation between corticosteroid production and body-size has been demonstrated.9-11 The possible influence of age and sex also needs to be taken into account in comparing such groups. Some of these difficul- ties might be resolved by relating plasma-cortisol produc- tion rates to body-weight or surface area. Even when carefully matched groups are compared, the influence of repeated stress, such as might result from asthmatic attacks, on adrenocortical reserves cannot be disregarded. PHENOTHIAZINE PIGMENTATION LAST year we discussed 12 a new side-effect attributed to chlorpromazine; and the first cases in this country have since been reported.13 Patients on long-continued high doses may get a bluish or slate-grey colour on exposed areas of skin, ’particularly the face. Sometimes ocular deposits also appear and they may impair vision. Chlor- promazine, in widest use, has been incriminated most often, but other phenothiazines can be responsible.14 The effect of the drug is cumulative and pigmentation appears gradually, especially during the summer. A dose of over 300 mg. a day for three years or more is usual, but shorter periods on higher doses may suffice. The pigmentation has been studied in the uveal tract of animals 15 and by histological techniques in the skin of patients.14 It is probable that phenothiazines accumulat- ing in the skin absorb wavelengths of light which cause an inflammatory reaction and an increase in melanin. At the same time phenothiazine is broken down and its metabolites combine with melanin to form a blue pig- ment. This product is refractory to further degradation and is disseminated throughout the reticuloendothelial system, causing a diffuse melanosis of the viscera, which has been seen post mortem.16 Endocrine or autonomic as well as local factors may be involved. Almost all reported cases were in women, many with amenorrha:a,17 suggesting a pituitary influence; -, and several phenothiazines are known to release melanin- stimulating hormone from the hypophysis in animals.18 Another contributory cause may be diminished secretion of pigment-lightening factor, melatonin, from the pineal gland, the result of an action of phenothiazines on the 6 Kass, I., Appleby, S.

PHENOTHIAZINE PIGMENTATION

LAST year we discussed 12 a new side-effect attributed to

chlorpromazine; and the first cases in this country havesince been reported.13 Patients on long-continued highdoses may get a bluish or slate-grey colour on exposedareas of skin, ’particularly the face. Sometimes ocular

deposits also appear and they may impair vision. Chlor-

promazine, in widest use, has been incriminated mostoften, but other phenothiazines can be responsible.14 Theeffect of the drug is cumulative and pigmentation appearsgradually, especially during the summer. A dose of over300 mg. a day for three years or more is usual, but shorterperiods on higher doses may suffice.The pigmentation has been studied in the uveal tract

STEPPING-STONE OR SHELTERED LIVING?

SINCE the Ministry of Health in 1959 directed localauthorities to provide hostels for patients who have latelyleft mental hospitals, there has been, with some honourableexceptions, a tardy response. Last year

20 we reviewedsome of the different kinds of accommodation that had

proved useful, and Dr. Peter Morgan 21 has now reportedanother successful enterprise at Newcastle upon Tyne.The hostel, a former commercial hotel, was opened inJanuary, 1963, by the local authority for dischargedwomen patients. Half came from a nearby hospital, andthe other half from outpatient departments and otherextramural sources. The hostel was renovated and has25 single rooms, with ample space for rest and recreation.It is run by a resident warden, deputy warden, cook, andtwo maids. There are a visiting psychiatrist, psychiatricsocial worker, and mental-health officers. Of the 32 resi-dents discharged in the first year, 15 have returned totheir own homes, 9 others have gone to lodgings, and 8to residential work. 6 were readmitted to hospital.The average length of stay in the hostel was about six

weeks, which is a good deal less than in other hostels ofthis kind. This may be partly determined by policy, forit was made clear in the first interview with the patient" that the hostel was a temporary and not a permanenthome". The local employment situation and goodsocial services of Newcastle may be other importantreasons.

The hostel at Newcastle follows the pattern of Cam-

bridge 22 and Birmingham 23 hostels. Its purpose is to

offer patients support until they are ready to resume inde-pendent lives in the community, and hostel placement isregarded as a phase in treatment. A different pattern isfollowed in the group of hostels in County Down, North-ern Ireland.z’ There the emphasis is not upon a half-wayhouse, though patients have left the hostels to rejoin thecommunity. The chief purpose of the scheme is to offera permanent home for suitable long-term patients outsidethe mental hospital. It seems clear that both kinds ofhostel are needed, and that both are an important partof the care of these patients.
