AT the last meeting of the Assembly of the League of Nations in September it was claimed that the League is now in possession of an effective instrument "’ four securing the limitation of manufacture and the regulation of distribution of narcotic drugs." The Assembly, nevertheless, expressed the view that such limitation of manufacture was but the " first step towards the limitation of the production of the raw material." It accordingly proceeded to instruct the Opium Advisory Committee to undertake, as soon as possible, the collection of material for a further conference on the limitation of the production of opium and of the cultivation and harvesting of the coca leaf. The representatives of some of the pro- ducing countries were not slow to point out the - economic difficulties in which the contemplated limitation of production would involve them, the Persian delegate remarking that the opium exports from his country amounted to 25 per cent. of its foreign trade. The report of the League of Nations Opium Commission in the Far East, dealt with in THE LANCET of Oct. 31st, fully confirms the contention that the radical method of dealing with the abuse of narcotics and the illicit traffic therein is by control of production at the source. The Assembly indeed recorded their opinion that " the enormous ravages caused by the illicit traffic revealed the fact that quantities of narcotics greatly in excess of those needed for medical and scientific requirements are being produced and circulated throughout the world." While there has been some recent reduction in the world manufacture of morphine and cocaine this appears to have been offset by an increase in the production of heroin. In 1930 more than 10 tons of pure narcotic drugs have leaked into illicit traffic. A conference is now sitting at Bangkok to deal with the traffic in opium " prepared " for smoking in the Far East, where the problem is complicated by a vast amount of smuggling. The evil has attained to such proportions that one of the American " observers " has reported to his Government that complete prohibition is the only method whereby it can be overcome. ____ END-RESULTS OF OPERATIONS FOR PEPTIC ULCER. THE comparative merits of resection and gastro- enterostomy for gastric and duodenal ulcers, as judged by the test of time, are discussed 1 boy Dr. Erik Brattstrom, of Prof. Petren’s Surgical Clinic in Lund, Sweden. His material consists of the patients operated on for chronic gastric or duodenal ulcer between Jan. 1st, 1900, and Dec. 31st, .1920. * The subsequent fate of these patients was investigated some 2 to 11 years after the operation, and this first inquiry was completed in 1923. In 1930 a second investigation of the same material was carried out. The pathological changes were approximately the same in the two groups, one of which consisted of 93 patients treated bv resection, and the other of 60 patients treated by gastro-enterostomy. The observation period for those living was, for the resection series, 8 to 21 years, and for the gastro- enterostomy series, 21 to 29 years. Good results could be claimed for 78 per cent. of the resections, and for 66 per cent. of the gastro-enterostomies. The incidence of cancer of the stomach developing after the operation was twice as high in the gastro- enterostomy group as in the resection group. Dr. Brattstrom concludes : " If then, finally, we should inquire into the question that constitutes the main object of the present investigation, namely, a comparison between the resected cases and those treated by gastro-enterostomy, we find an undoubtedly greater percentage of good results on the part of the resections." He finds, however, that what he calls the " stability " of the results after operation was . a little more favourable for the gastro-enterostomies than for the resections.

STERILISATION OF YEASTS AND FUNGI.

SOME recent laboratory experiments by E. Kadischdeserve notice because his observations affect not

only dermatologists but all who are trying to discovertherapeutic weapons against the mycotic group of

organisms. His paper, of which the second instal-ment has now appeared,2 is highly technical, but theconclusions may be quoted. He finds that smallpieces of cloth smeared with the agar-culturedcolonies are a practical, reliable, and easily handledmaterial for sterilisation tests. The resistance of theorganisms is often variable, and sometimes greaterthan was expected-both facts being probably depen-dent on the protective character of the agar in whichthey grow. The resistance of the naked organismdepends on its type and age. Yeasts are more

resistant than mycelial fungi of the epidermophytongroup, and Aspergillus niger, which he regards as apure parasite, is more resistant than the pathogenicvarieties of fungi. Alcohol he finds to be a valuabledisinfectant, and thymol will kill Oidium albicans(the cause of thrush) in a concentration of only 1/2000in glycerin broth in 48 hours. A 1 per cent. solution

of thymol in commercial alcohol proved a reliable anti-mycotic agent, and it is interesting to note that anincrease in the concentration of the drug did not haveany marked influence in reducing the times-minutesfor the mycelial group, and hours for the yeasts-in which the results were achieved. Kadisch statesthat silk stockings, for instance, can be disinfectedof all mycotic organisms, both fungi and yeasts,by six hours’ immersion in this fluid.

GYNÆCOLOGY IN VIENNA,

THE large volume before us 1 describes the techniqueof operative gynaecology employed at the First

University Women’s Clinic, Vienna, and the resultsobtained there. The opening section is devoted to adescription of the precautions against infection,anaesthesia. (including a very detailed descriptionof local and sacral anaesthesia), post-operativecomplications, general operative technique, and

preparatory and after-treatment. The second sectionis given to anatomy, and the third and last sectionto descriptions of the various gynaecological operations,starting with cancer of the cervix, to which 160 pagesare devoted, mostly occupied by a detailed description,with plates, of the extended vaginal operation whichis chiefly used by the authors, though a very full andbeautifully illustrated description of radical abdominalhysterectomy is also given. The numbers of casesdealt with are impressive. Thus between the years1901 and 1920 were seen 1787 cases of cancer of thecervix, and from 1921 to 1925 a further 461 cases, ofwhich 258 were operable-an operability-rate of 56 percent., the primary mortality-rate being 6.6 per cent.In most cases the extended vaginal operation wasdone. From Jan. lst, 1921, to May 31st, 1922,161 cases were seen, and of these, 92 came to operation,82 of which were done by the vaginal route, and 10by the abdominal. In this group the primarymortality was 9-8 per cent., the five-year cure-

rate being 26-7 per cent. of all cases seen (161).The results which are given in detail will repay carefulstudy. Few cases seem to have been treated by radium,and the results obtained are, on the whole, poor,though of 249 inoperable cases treated by radiumbetween 1913 and 1919, 26 (10.5 per cent.) were wellin 1924. From 1921 to 1925 (five years), 921 myomaswere seen in the clinic, 620 of which came to operation.In 349 vaginal hysterectomy was done with onlyone death, while supravaginal hysterectomy was

carried out in 176 cases with six deaths, and totalabdominal hysterectomy in 69 cases with six deaths ;the total death-rate in the series being 1-6 per cent.Cancer of the cervical stumps the authors found to berare, only eight cases in 1253 supravaginal hysterec-tomies. As the frequency of cancer of the cervixin the general population is 0-025 per cent., theconclusion is reached that subtotal hysterectomypredisposes to cancer in the stump. Since howeverthe patients know that menstruation has finished,and therefore do not expect bleeding, they comeearly, and so most cases are operable. The absenceof menstruation and accompanying hyperaemia tendto limit infiltration of the parametrium, so that of 13cases in the authors’ experience only two were inoper-able. Of metropathia hsemorrhagica 580 cases wereseen in the five years from 1921 to 1925 ; of these,

239 were treated by vaginal hysterectomy, of whichfour died, and 332 were treated with X rays-success-fully in all but seven cases. In treatment of cancerof the body, operation by the vaginal route is againfavoured. The results from radium have been poor; xit was used in nine cases, of which seven were operable,and only one of them was completely cured. For retro-version the Baldy operation is preferred. Eighteenpages and 15 colour plates are occupied with inter-positio uteri. A feature of the book is the beauty ofthe illustrations, all but two of which are original.The book, which is a notable addition to gynaeco-logical literature, constitutes the last work from thepen of the late Prof. Peham, and really amounts to arecord of his unique and lifelong experience.

SERUM IN ACUTE POLIOMYELITIS.

THE value of immune serum in the treatment ofthe acute stages of anterior poliomyelitis is nowfirmly established,1 but it is difficult to get a readyand sufficient supply. In America some workershave adopted the practice of collecting and poolingsmall quantities from patients recovered from thedisease. This, however, is not altogether devoid offallacies, as Shaughnessy, Harmon, and Gordon a

have shown, since they found that of seven personswho had been attacked by poliomyelitis from 6 to 24months previously in only four was the serum potentto neutralise the virus. But in addition theseworkers confirmed the previously recognised fact thatthe serum of many people who have never sufferedfrom the disease contains immune bodies in highconcentration. For these reasons H. K. Faber 3,

urges firstly, that all convalescent serum intended tobe used therapeutically should be tested, and,secondlv, that bv testina the serum of transfusiondonors a large and readily accessible supply ofimmune serum could be obtained. It was foundthat 77 per cent. of the donors tested were immuneand use was made of this fact in the recent epidemicin California with satisfactory results. M. Neustaedter 4has attacked the problem from a different aspect.Despite Flexner’s original failure, he has attemptedto immunise horses to the virus of poliomyelitis,and he succeeded in producing a serum which is

capable of protecting monkeys from large intra-cerebral injections of potent virus. Pettit and otherFrench workers have confirmed his findings and reportthe successful use of this serum clinically. In thiscountry R. W. Fairbrother and W. T. J. Morganhave done a good deal of work on the immunisationof horses, and a limited supply of their serum isavailable for tria1,1 but so far they have not drawnconclusions about its clinical efficacy.5 5 Meanwhilethese results are of great interest, and prompt oneto hope that eventually we shall have a supplyof efficient serum for use whenever necessary.
