Child PsychiatryModern Approaches. Edited by MICHAEL RUTTER, F.R.C.PSYCH.Institute of Psychiatry, and LIONEL HERSOV, F.R.C.PSYCH., Beth-lem Royal and Maddstey Hospitals. Oxford: Blackwell. 1977. Pp.1024. 21.50.

CHILD psychiatry has undergone several metamorphosessince its infancy in the 19th century. It began with paediatricobservations, became attached to neurology, submerged for atime in various psychoanalytic theories, was administrativelyclaimed by adult psychiatry, education, and social services, butis at last emerging as a true medical entity. This book consistsmainly of review articles of research and thinking in this newclinical discipline. The contributors are generally connectedwith work done over the past 15-20 years in the children’s

department of the Maudsley Hospital, London. The bookoffers a confirmatory statement of the existence of child psychi-atry. However, it is also an essential source of references tocurrent thinking and research. It is difficult to select from somany contributions (there are 41), but the chapters on individ-ual differences, genetics, and antisocial conduct seem particu-larly important to the new thinking about early identificationand prevention of at least some child psychiatric problems.There are helpful accounts of adoption, diagnostic appraisal ofdisturbed children, psychological testing, and language dis-orders. The book is less helpful on treatment-with a fewexceptions, notably the management of disturbed adolescents,mentally handicapped children, and behaviour modification.Antidepressants are handled cautiously: there is a categoricalstatement, in the chapter on enuresis, that tricyclics should notbe given to children younger than 4 years, and the chapter onhyperactive children states that imipramine may not be givento children younger than age 12, except for enuresis. The bookshows evidence of haste in production. There are numerousmisprints and occasionally unhappily worded phrases, and inat least two places text seems to have been omitted. Overallthis book can, however, be warmly recommended as a refer-ence source and an authoritative statement of current thinkingin most aspects of child psychiatry.

Doing Better and Feeling Worse

Health in the United States. Edited by J. H. KNOWLES, M.D. NewYork: Norton. 1977. Pp. 287.$9.95 (paperback$3.95). York: Norton. 1977. Pp. 287.$9.95 (paperback$3.95).THIs book is the result of deliberations on the state of medi-

cine in America by twenty doctors, economists, and politicaland social scientists. Nelson Rockefeller, chairman of the Com-mission on Critical Choices for Americans, invited Dr Knowlesof the Rockefeller Foundation to coordinate this inquiry. Thecommon theme is similar to that of T. McKeown’s Role ofMedicine, A. L. Cochrane’s A Question of Quality, and evenIvan Illich’s Medical Nemesis. Aaron Wildawsky (RussellSerge Foundation) concludes: "According to the Great Equa-tion, Medical Care equals Health. But the Great Equation isWrong. More available medical care does not equal betterhealth ... Most of the bad things that happen to people areat present beyond the reach of medicine". This is the dilemma,coupled with the rising expectations of American (and other)societies, that the authors discuss at length and unanimouslyagree upon. As Walsh McDermott (Cornell University) puts it:"Today’s often repeated cliche that what the physician doeshas relatively little influence on health is more correctly statedthat what the physician does has relatively little influence onthose indicators of health that are largely irrelevant to whathe does".The nineteen chapters cover a wide range of subjects-from

increased "medicalisation" of American society, ethics, thecontribution of technology, primary care, relationshipsbetween government, consumer, and provider, to specific caregroups, such as the mentally ill and children, and to researchneeds and health finance. There is some overlap betweenchapters, and several chapters analyse the major problems fac-

ing the American health "industry": Few references are givento other countries, but issues such as national health insur-ance, private medicine, training for primary care, and methodsof financing research and medical education are of interest toall involved in health-care policy. This book is neither a

defence of medicine nor an attack on it: rather it is a critical

analysis of what medicine should be achieving. Several con-tributors make the point that we have reached a half-way stageof development. While many major advances have been madethese advances are very limited compared to what could bedone. The need for major changes in life-style does comethrough in this book, though perhaps not as forcibly as else-where. Daniel Callahan (Institute of Society, Ethics and the ’

Life Sciences) says that two social realities bedevil the task ofaltering people’s expectations. "The first is the almost total

breakdown of the ethical distinction between ’need’ and ’desire’ in our culture. The second, closely related to the first, is the continuing utopian lure of technology, the lure whoseeffect is to thwart any attempt to place limits on medical aspir-ation". Of the increasing costs of health care Lewis Thomas(Memorial Sloan-Kettering Cancer Centre) writes: "If our so-ciety wishes to be rid of the diseases, fatal and non-fatal, thatplague us the most, there is really little prospect of doing soby mounting a still larger health-care system at still greater

cost for delivering essentially today’s kind of technology on alarger scale". Eli Ginzberg (Columbia University) continuesthis theme: "... while the health-care system is responsive tothe most urgent needs of most of the population, there is noprospect whatever, no matter how much money we invest in Iit, for the system to serve as broad support for the host of illsthat already beset modern man and that may well multiply in the years ahead. In consuming over 8 per cent of the gross Inational product the health-care system is crowding the mar-

’gins of family and public income, and we should consider care-fully what we are likely to buy if we increase our expenditureto any significant degree".

These quotes reflect the flavour of this impressive collectionof essays. Nothing new is in this book but what is said is saidwell and said with the authority of those who shape opinionin the United States. But why does not the message get acrossto the public, professions, and governments? Despite whatMcKeown, Cochrane, and Illich-and now this highly res-

pected group-have said little notice is taken at the opera-tional level.

Manual for Disaster Relief Work

MURIEL SKEET, British Red Cross Society. Edinburgh: ChurchillLivingstone. 1977. Pp. 412. £ 12.

TRAINING for catastrophes can be basic or particular. Per-sonnel who may have to deal with crises as different as a hurri-cane in the tropics or a flood in near-arctic conditions, mustbe well versed in the general problems of rescue and survival.Those preparing for nuclear disasters require other, and veryspecific, skills. This manual makes a praiseworthy attempt toserve both groups. Such an encyclopaedic approach has inevi-tably led to the inclusion of some material which seems too eso-teric for any common emergency. It is not an exclusively medi-cal book, but the clinical features of actinomycosis are listedin detail, and there is a two-page list of fifty-eight arthropod-borne viruses. The notes on gunshot wounds feature instruc-tions for "fabricating a sizeable vein graft", though it is easierto imagine circumstances in which the text would be consulted,to no avail, upon the moot point as to whether T.A.B. vaccina-tion is dangerous when an epidemic has already broken out.There is a wealth of most valuable information in the book;some of it not easily to be found elsewhere. The best sectionsare those dealing with the urgent, elementary aspects of reliefwork. Future editions would be enhanced by a less academicapproach, and by references to past disasters and the lessonsto be learnt from them.
