which in return are often adopted widely for thecommon good. CtTSHiNG always insisted, however,that the freshness of these young branches must notobscure the primary function of general medicineand surgery, with its role of support and linkage,both in training and in treatment. The necessarybalance in outlook is one that can be achieved onlythrough inspired clinical leadership, not by administra-tion, and CuSHiNG’s own life is an example of thatinspiration. He showed that the specialist can andshould have an influence far beyond his own sphere,and should add to the strength of the parent stock,instead of taking it away. And incidentally hisqualities of mind and heart made him what he alwayswanted to be-a good doctor to his patients.

CARE OF THE CHILD AFTER POLIOMYELITIS
WHEN children leave hospital after a bout of polio-myelitis, nicely booted and callipered, is there any moreto be done 1 The parents can be told that there is achance of further recovery of muscle power up to 18months after the onset of paralysis ; and that, later on,an arthrodesis, transplantation of tendons, or sympa-thectomy may diminish the patient’s disability. It isalso worth discussing how they themselves propose totreat the child in his daily life, for much depends on this.It is sensible to guide a crippled child towards intel-lectual and artistic activities, but the over-ambitiousparent should be reminded that, though her offspringmay become a Roosevelt, he can easily be strained
beyond his capacity and be additionally disabled byanxiety ; or, particularly at a boarding-school, he may
develop a disproportionate envy of his athletic colleagueswhich may haunt him beyond his schooldays. Physicalrecreation should be discussed with the parents; for itis common to meet crippled children, or adults crippledin early life, whose incapacity has never been questionedbecause of their outward appearance, so they finallydo not know what they cannot do, what they are afraidto do, and what they have never acquired the habit ofdoing. Exercise also has important social and symbolicvalues, apart from its physical benefits, and there aredangers in a purely intellectual life.Many normal children feel insecure, and a lower-limbpalsy may turn a phantasy of insecurity into reality.Confidence can be restored by games in which balance iscontrolled mainly by other muscles than those of thelegs. Diving involves poise in the air by means of trunkand neck muscles. - The legs -are of minor importance,particularly in diving off a spring-board, and any childwho can hop or jump a few inches can enjoy this sport.Bicycling in fairly flat country can be performed by achild with one or even half an active leg, provided thata light machine, with a three-speed gear and a fixedwheel, is used. Horse-riding, for those who can afford it,is more a matter of balance than of leg-grip and iswithin the capacity of many apparently disabled olderchildren. The physical exercise of power is also missedunnecessarily by some of these children. If shouldermuscles are weak, a golf shot of fair length can still bemade with wrists and forearms. Municipal golf-coursesand artisans’ clubs are scattered over Britain, thoughmore thickly in the north. Six or seven years is probablythe best age for a child to learn to swim, but four-year-olds can be taught, even ii their legs are paralysed.Leg action is essential in the breast-stroke but of minorimportance in the crawl, and swimmers such as Arne Borgobtained nine-tenths of their propulsive power fromthe arms. An exercise suitable for those with one weak
upper or lower limb is jujitsu. One of the principles of
this art is that the opponent, though rendered incapableof doing injury, should not himself be injured. Itsmoral value is considerable, and instructors can befound in clubs in most large towns. The overt aim in allthese activities should be that of achievement ratherthan competition, for failure in competition is more
likely to dishearten the partially paralysed than the fit.Esthetics must not be neglected. A case of polio-
myelitis should be reviewed at intervals, when perhapsa walking-iron which was helpful and unobjectionableon rough fields may be discarded while going to schoolthrough town streets under the eye of other children.A night splint alone may be sufficient to prevent a drop-foot from contracting after the first year of the disease.An early promotion to long trousers can make a smallboy the envy of his friends and hide a withered limb ofwhich he is more conscious than he seems. A paddedstocking or padded shoulders for a fourteen-year-oldgirl are more justifiable artifices than lipstick. Onecannot dogmatise about individuals of different characterwho resemble one another only in having weakness ofone or more muscle groups. But it may be said thatthe mental effects of poliomyelitis often outweigh thephysical and are no less amenable to prevention andtreatment.
DANGERS OF GLOVE POWDER
TALC granuloma is now a recognised late complicationof operation wounds, though few surgeons would beprepared to diagnose it clinically. A more serious resultof contamination of the peritoneum with glove powderhas been described by Roberts 1-granuloma of the
fallopian tubes, producing sterility. This disastrousresult of an otherwise uncomplicated operation had notpreviously been recognised because the symptoms arenot very severe and may take several years to appear ;and when the tubes are examined histologically the
similarity to tuberculous granuloma is close enough toconfuse the diagnosis. Several of the tubal lesionsdescribed by Roberts had previously been diagnosed astuberculous, and only the detection of doubly -refractivematerial in the sections revealed their true nature.Roberts has raised the question whether some cases
diagnosed histologically as tuberculous endometritis maynot also be silicious granuloma, since the talc may passvia the fimbriated ends of the fallopian tubes to theendometrium.The long latent period between the original operation
and the detection of the granulomata is well illustratedby the history of the seven cases reported by Roberts.Each patient had had a previous appendicectomy. Two
patients came under observation on account of swellingof the scar, one 12 and the other 11 years after operation.The scars excised resembled keloids, and were nodularon section. Histologically the mass in each case wascomposed of multiple follicles containing giant andendotheloid cells. Numerous small anisotropic particleswere demonstrated with the polarising microscope.These were intimately related to the giant cells, whichwere in the main grouped around them, and theirsilicious nature was established by microchemicalmethods. The five other cases in Roberts’s series allhad granulomatous changes in the fallopian tubes, andhistological examination revealed the same intimate
relationship of anisotropic particles to-giant cells, the
particles sometimes being actually inside the cells.
Appendicectomy had been performed in these cases
2, 17, 10, 8, and 11 years before the pelvic operations.Only one of the patients had become pregnant after theappendix operation, and this single pregnancy hadended in abortion. All the women were married andwere apparently sterile. Their symptoms suggested alow-grade pelvic inflammation.

Further evidence of the irritating effect of glovepowder on the peritoneum appears in the experimentalwork on dogs done by Lee and Lehman 2 in the UnitedStates. Small quantities of powder from the surface ofrubber gloves introduced into the peritoneal cavityproduced a violent peritoneal reaction with denseadhesions between the coils of gut. These writers thinkit dangerous to use talc on surgical gloves, so they havebeen looking for an efficient substitute. They havechosen a commercially prepared dusting powder derivedfrom corn starch, which is treated by physical andchemical means so that it no longer tends to agglutinatein the autoclave and thus lose its lubricating power, asdo many other physiologically safe powders. The flowand fineness of the powder are unimpaired by auto-
claving, and its complete absorption from the peritoneumhas been proved experimentally. A brief clinical trialhas demonstrated its practical efficiency, and autoclavedsamples have proved completely sterile. An alternative
powder has been prepared by Correll and Wise 3 fromgelatin flour. They have rendered the gelatin relativelyinsoluble in water and at the same time amenable toproteolytic digestion in vitro by subjecting the finelyground flour to a temperature of 145°C in an electricoven for 25 hours. The denatured powder has proved asatisfactory lubricant. When injected into the peri-toneal cavity of rats it produced no granulomata, and itwas completely absorbed by the end of 4-5 weeks.
Surgeons should be aware of the potential dangers oftalc powder and be willing to give a trial to substitutes.In the meantime surplus powder should be washed offthe outside of gloves before operations begin ; nurses
should be careful not to load the finger tips with excesspowder which may escape if the glove is punctured;and if a puncture is suspected the gloves should certainlybe changed before the hand is used to manipulate thecontents of the peritoneal cavity.
CAUDAL ANALGESIA IN CHILDBIRTH
To the obstetric anaesthetist asked to assess the valueof a new technique the fundamental question is-doesthe new method effectively relieve pain without increasingthe risk to mother or child 1 This can be answered onlyby the statistical analysis of a large series of cases,, andthis has now been done for caudal analgesia 4 with’Metycaine,’ .as introduced early in 1942 by Edwardsand Hingson.5 Analgesia by this method can be startedearly in labour and maintained throughout delivery, andwhere necessary continued for postpartum repair.
In 2516 deliveries conducted at the PhiladelphiaLying-in Unit of the Pennsylvania Hospital caudal
analgesia produced complete relief from pain in 90-4%of the mothers ; in only 5-3% was no alleviation obtained.On the other hand, there was a drop in systolic blood.pressure of more than 25 mm. Hg in a third of themothers. Whether this implies any added risk to motheror child can be determined only from a controlled com-parison. Ideally, the control group should be drawnfrom a concurrent series of deliveries differing only inthe method of analgesia employed. Since this was
impracticable comparisons were made with a series of1024 cases delivered in the previous spring and summer.The two groups were very similar in all the main factorslikely to influence maternal and child mortality-age,parity, previous health, and so on-and it was thoughtunlikely that time trends, such as seasonal swings inepidemic disease or new therapeutic advances, invali-dated the comparisons. The outlet forceps rate wasrather higher among the caudal group (68%) than
among the controls (56%), but less blood was lost andthe incidence of pyrexia and subinvolution was lower in2. Lee, C. M., Lehman, E. P. Surg. Gynec. Obstet. 1947, 84, 689.3. Correll, J. T., Wise, E. C. Science, 1947, 105, 529.4. Collins, S. D., Phillips, F. R., Oliver, D. S. Publ. Hlth Rep.,

the group given. caudal analgesia. Only 2-5% of theinfants in the caudal-analgesia group required respiratorystimulants, compared with 8-7% among the controls,whose mothers had usually received inhalational anms-thetics such as nitrous oxide and ether.
’
The most striking finding was the reduction in still-birth and neonatal (’up to one week) death-rates : in the’caudal-analgesia group the stillbirth-rate was 9-1 per1000 live births, compared with 24-8 per 1000 in thecontrol group, while the neonatal death-rates were 11.5and 20-8 per 1000 live births. These differences couldnot be explained by any differing incidence of prema-turity-incidentally, caudal analgesia seemed less harmfulto the premature infant-and they were unlikely to haveoccurred by chance. The authors of the report calculatethat the employment of this method in all deliveries inthe United States with the same results would halve thepresent annual loss of 125,000 viable infants ! It would,of course, be impracticable to use caudal analgesia fordomiciliary- confinements, but this careful and compre-hensive American account should be seen by all concernedwith lessening the pain and hazard of labour conductedin hospital or maternity home.
CONVALESCENT HOMES
UNDER the National Health Service Act the definitionof a hospital includes " any institution for the receptionand treatment of persons during convalescence or personsrequiring medical rehabilitation." This is a very widedefinition and there has been much speculation on howit would be construed, especially in relation to con-
valescent homes.It is now announced that the homes owned and
managed by the Birmingham Hospitals Saturday Fundhave, with one exception, been excluded from the
operation of the Act. The criterion has been the amountof treatment given, and apparently the Minister hasdecided that these homes do not give enough to warranttheir inclusion in the National Health Service. All ofthem have a matron and an assistant matron who areState-registered nurses, and some of them have a fewassistant nurses as well; but the Birmingham HospitalSaturday Fund argued that these are really administra-tive staff. Their nursing qualifications are requiredonly in an occasional emergency such as an accidentor an unexpected relapse, and in either of these eventsthe patient is much in the same position as an ordinarymember of the public, being nursed in the home if theillness is trivial or sent to hospital if it is serious : thestaff of the homes do not undertake any serious treatment.
Again, though the homes have an honorary medicalofficer, who is available if required, he is more comparableto the family doctor than to the resident physician ina hospital.
This decision will be of great interest to all those
responsible for the management of convalescent homes.
CLINICAL CYANOSIS
THE clinical assessment of the degree of cyanosis is
notoriously difficult, even to -the observer with an artisticeye, and the clinical detection of slight cyanosis is noeasier. According to Lundsgaard and Van Slyke,cyanosis will not be detectable until 5 g. of reduced
haemoglobin is present in 100 ml. of capillary blood,which corresponds to an arterial oxygen saturation of80%. Stadie,2 however, found that the correlationbetween arterial oxygen saturation and clinical assess-ments of cyanosis varied considerably. For instance, in12 patients with " moderate cyanosis " the saturationranged from 65% to 91%, while in 12 patients with" marked cyanosis " the saturation ranged from 56%to 86%. Comroe and Botelho 3 have now measured the
