Rabies was diagnosed in bats only, and all but 2 of the 104 positive bats were E serotinus. No other animal was positive either in FA or by inoculation test even though many of the cats and foxes were sent of bat rabies. in from areas in Jutland with a high FA and inoculation studies on serotine bats are shown in table 11. (Of the 2 FA positive Myotis spp, 1 was confirmed by isolation in mouse brain.) Of the 104 bats positive by FA, material from 101 was available for IFA with monoclonal antibodies. All 101 specimens reacted similarly in IFA, confirming that these strains belonged to the rabies virus group, but not to serotype 1. Bat rabies was concentrated in southern and eastern Jutland: 88 (32 %) of 276 serotine bats sent in from the four counties in this part of Jutland were found positive. Positive bats were found in all months from June to October with a peak in August. Rabies in Danish bats was further studied by neutralisation tests on serum from 10 apparently healthy serotine bats, 9 of them being from a rabies positive colony in south-east Jutland; the other was trapped in a house where bat rabies had been diagnosed previously. FA titres were 100 in 4 bats, 10 in 4 bats, and less than 10 in 2 bats. Thus DBV-antibodies were detected in apparently healthy bats. Findings in Denmark and Germanyl° indicate that bat rabies is more common in Europe than most people think. DBV can infect and kill in the laboratory8 but our field data seem to indicate that bat rabies is rarely transmitted to other mammals. The absence of bat rabies in terrestrial animals from an area of Denmark with a cluster of bat rabies could indicate that an epizootic of bat rabies in terrestrial animals will not be readily established. 11

following changes: fewer new intravenous drug abusers, less use of the intravenous route, less sharing of needles and syringes, or active immunisation. Why should these changes have happened in 1985-86? Hepatitis B is a long-established hazard of unsterile needles and syringes: although public awareness of hepatitis B infection as a risk of intravenous drug abuse may have increased it seems improbable that this alone is sufficient to have reversed the trend. However, public warnings of the risk of acquiring the human immunodeficiency virus may have had a sufficient deterrent effect limiting intravenous drug abuse or persuading abusers not to share equipment. There can be no certainty that fear of AIDS has led to a decrease in acute hepatitis B infections but if it has acute hepatitis B reports would be encouraging evidence of the value of publicity campaigns in curbing practices that favour the spread of AIDS.

LONG-TERM FOLLOW-UP AFTER BONE-MARROW TRANSPLANTATION IN ACUTE LYMPHOBLASTIC LEUKAEMIA

SIR,-A 1986 Lancet article by Chessells et all generated lively correspondence. We wish to emphasise the curative intent of bone-marrow transplantation (BMT) and the need to report data after a follow-up of 5 or more years. We have reported on 21 children with acute lymphoblastic leukaemia (ALL) who relapsed, achieved second remission, and were treated with chemotherapy and a concurrent group of 24 patients who had a donor and were treated with BMT while in a second or subsequent marrow remission.2 Initial induction therapy was given in several institutions but, after first relapse, all patients were treated in a single centre by the same team of physicians. In a follow-up, all children treated with chemotherapy had relapsed and

DECREASE IN ACUTE HEPATITIS B INCIDENCE IN ENGLAND AND WALES IN 1985-86

SIR,—The annual total of laboratory reports of acute clinical hepatitis B to the Public Health Laboratory Service, which ranged from about 1000 to 1200 during the years 1975-83, rose sharply to almost 2000 in 1984. Thereafter, however, there has been a sharp fall to about 1300 in 1986. Drug abusers have consistently constituted the largest single group, and fluctuations in the annual totals of acute hepatitis B have been due mainly to changes in numbers of addicts. The number of cases with a history of drug abuse increased from less than 300 in 1983 to about 600 in 1984 and then fell to about 300 in 1986 (figure). Male homosexuals have constituted a smaller portion of the total but their numbers also fell from a peak of 150 in 1984 to less than 100 in 1986, the smallest annual total for this group since 1981. The observed decline in drug abuse associated cases must have been due to one or more of the

YEARS

Kaplan-Meier product limit estimates of disease-free survival for 14 children given BMT for ALL in second remission. . = long-term survivor.

381 died by 3 years while 8 of the marrow-grafted patients continued in untreated remission3 and these 8 are in remission to this day. 14 of the 24 were transplanted in second remission. The figure shows actuarial survival with 4 of the 14 in event-free survival after 7-10 years. In addition to the marrow relapse, 1 of these 4 had a central nervous system (CNS) relapse, and 1 a CNS and ovarian relapse. All 4 surviving patients lead normal lives and attend high school or college. Late effects of transplantation include cataracts in 3 and primary ovarian failure in 1. All had normal growth and the 3 who were prepubertal at transplantation developed normally through puberty. As several of your correspondents say, the results of chemotherapy are improving and the same is true for BMT. However, the optimum age, type and stage of leukaemia, and appropriate prognostic indicators for BMT are controversial.3 The answers will come from prospective studies but "rapid advances in chemotherapy regimens and in marrow grafting regimens are likely to invalidate the results of a prospective study by the time it is completed".4

report here our experience with it during the pilgrimage season of 1406 AH in the muslim calendar (August, 1986). A patient trolley (75 x 180 cm) was constructed (figure) with a stainless steel tray to limit water spillage and to wash away excreta. Two fans with 35 cm diameter blades direct room air over the patient and Extech thermocouples are used to measure core and body surface temperatures. The patient is undressed and covered with a fine gauze sheet soaked in water at 20°C. The maximum speed of airflow, 50 cm below the centre of the fan at the top of the bed, is 2-6 m/s. The skin temperature was kept at 30-32°C, if it fell below 30°C the speed of the fans was reduced. We treated 25 consecutive patients (17 males, 8 females) with heatstroke; cooling was started immediately, using the cooling bed. Other medical problems, such as convulsions, were treated by standard medications.1,6 SUMMARY OF RESULTS

The rectal temperature was reduced to 39°C in 40 min on average, at a rate ofO’087OCjmin, at which point unassisted cooling was resorted to. 19 patients recovered completely within 24 h. The other 6 also recovered, but aspiration pneumonia developed in 3, intubation was required in 2, and 1 patient had low platelet count but no evidence of disseminated vascular coagulopathy or bleeding.

reported for the cooling unit introduced by Weiner and Khogali. 6,7 Another advantage is the cheapness, portability, and simplicity of the unit, so that it can be used at any health centre near the pilgrimage camps and gatherings.

SIMPLIFIED COOLING BED FOR HEATSTROKE

SIR,-Heatstroke is a major hazard of the annual pilgrimage to Mekkah, the Haj, in which some 2 million muslims take part.l,2 For the next fifteen years this pilgrimage will be in the summer months, as high as 48°C in the shade. Rapid cooling has proved helpful in heatstroke,3though immersion of the patient in a tub of iced water has many disadvantages.4 Evaporative cooling has been more effective,2,s,6 and a specially designed body cooling unit was introduced for this purpose? Though effective its practical application on a wide scale has been questioned.2,8The unit is expensive, needs trained personnel, takes up a lot of space, and has to be installed in a special treatment centre. To overcome these difficulties we designed a simple cooling bed, the King Saud University cooling bed, and
