The British Columbia Positive Women's Survey: a detailed profile of 110 HIV-infected women

OBJECTIVE: To describe the health, social environment, medical care received and satisfaction with medical care of HIV-infected women in British Columbia. DESIGN: Self-administered 75-item questionnaire distributed by mail or in person between March 1994 and February 1996 through community AIDS organizations and physicians'' offices. SETTING: British Columbia. PARTICIPANTS: A total of 110 HIV-positive women. OUTCOME MEASURES: Sociodemographic data, risk factors for HIV infection, details about HIV testing, health status and medical treatment, use of health care services, degree of satisfaction with medical care and psychosocial stressors. RESULTS: Most of the women surveyed were aged 25 to 39 years (70.0%), were Canadian born (76.4%) and were white (80.9%). Over one-third did not complete high school, and half had an annual household income of less than $20,000. Of the 110 women 51.8% had children, who were HIV-positive in 12.3% of cases. The most frequently reported risk factor for HIV infection was sex with a man (49.1%); 19.1% reported both sex with a man and injection drug use, and 12.7% reported injection drug use only. Seventy-five women indicated that they had become infected through sex with a man, with or without injection drug use. Of these, 65 indicated whether or not this was the result of sexual assault or rape; 8 (12.3%) answered affirmatively. Of the 81 women who responded to the question regarding prior sexual assault or abuse, 43 (53.1%) reported being sexually assaulted as an adult, 35 (43.2%) reported being sexually abused as a child, and 22 (27.2%) reported being sexually abused or assaulted both as a child and as an adult. Women who were sexually abused as a child were more likely than those who were not abused as a child to have injection drug use as a risk factor (54.3% v. 7.5%). Menstrual cycle changes were reported by 70.1% of the respondents. Most women stated that they had not received adequate pre- or post-test counselling, and 47.0% were not satisfied with their doctor''s care. Psychosocial concerns identified to be of greatest importance were financial problems, lack of intimacy or satisfying sexual relationship, and fear of rejection or discrimination. CONCLUSION: Several important concerns for HIV-positive women were identified, including dissatisfaction with medical care, fear of discrimination, violence and abuse, and poverty.     

Babies with spina bifida treated without surgery: parents' views on home versus hospital care.

From 1971 to 1981, 98 babies born with meningomyelocoele at the North Staffordshire Hospital Centre''s district maternity hospital, were thought not suitable for surgery. Sixty three survived for more than one week. Over the period the hospital''s policy changed: initially all such babies were kept in hospital, but later parents were given the choice of taking their baby home for palliative and terminal care. In an attempt to determine parents'' views on the care of their baby the parents of 44 of the babies who survived to one week were traced in 1985-6, five to 14 years later; 80 of them were asked how they felt about the lives and deaths of their babies. Eighteen babies had been taken home, and they had lived longer than the 26 who had been cared for in hospital. Parents whose baby had remained in hospital were sadder than those who had taken their baby home when they looked back at their experiences, and they also considered that their baby''s life had been of poor quality. Most of those who had taken their baby home had a more positive view of their child''s life. The figures suggest that the bereavement process after a baby''s death is longer than has been thought, but despite residual sadness just over half of the parents interviewed thought that something positive had come out of their experience.     

Results of case-control study of leukaemia and lymphoma among young people near Sellafield nuclear plant in West Cumbria.

OBJECTIVE--To examine whether the observed excess of childhood leukaemia and lymphoma near the Sellafield nuclear plant is associated with established risk factors or with factors related to the plant. DESIGN--A case-control study. SETTING--West Cumbria health district. SUBJECTS--52 Cases of leukaemia, 22 of non-Hodgkin''s lymphoma, and 23 of Hodgkin''s disease occurring in people born in the area and diagnosed there in 1950-85 under the age of 25 and 1001 controls matched for sex and date of birth taken from the same birth registers as the cases. MAIN OUTCOME MEASURES--Antenatal abdominal x ray examinations, viral infections, habit factors, proximity to and employment characteristics of parents at Sellafield. RESULTS--Expected associations with prenatal exposure to x rays were found, but little information was available on viral illnesses. Relative risks for leukaemia and non-Hodgkin''s lymphoma were higher in children born near Sellafield and in children of fathers employed at the plant, particularly those with high radiation dose recordings before their child''s conception. For example, the relative risks compared with area controls were 0.17 (95% confidence interval 0.05 to 0.53) for being born further than 5 km from Sellafield 2.44 (1.04 to 5.71) for children of fathers employed at Sellafield at their conception, and 6.42 (1.57 to 26.3) for children of fathers receiving a total preconceptual ionising radiation dose of 100 mSv or more. Other factors, including exposure to x rays, maternal age, employment elsewhere, eating seafood, and playing on the beach did not explain these relationships. Focusing on Seascale, where the excess incidence has predominantly been reported, showed for the four out of five cases of leukaemia and one case of non-Hodgkin''s lymphoma whose fathers were employed at Sellafield and for whom dose information was obtained that the fathers of each case had higher radiation doses before their child''s conception than all their matched control fathers; the father of the other Seascale case (non-Hodgkin''s lymphoma) was not employed at the plant. These results seem to explain statistically the geographical association. For Hodgkin''s disease neither geographical nor employment associations with Sellafield were found. CONCLUSIONS--The raised incidence of leukaemia, particularly, and non-Hodgkin''s lymphoma among children near Sellafield was associated with paternal employment and recorded external dose of whole body penetrating radiation during work at the plant before conception. The association can explain statistically the observed geographical excess. This result suggests an effect of ionising radiation on fathers that may be leukaemogenic in their offspring, though other, less likely, explanations are possible. There are important potential implications for radiobiology and for protection of radiation workers and their children.     

Case-control study of leukaemia and non-Hodgkin's lymphoma among children aged 0-4 years living in west Berkshire and north Hampshire health districts.

OBJECTIVE--To investigate the relation between parental employment in the nuclear industry and childhood leukaemia and non-Hodgkin''s lymphoma. DESIGN--Case-control study. SETTING-West Berkshire and Basingstoke and North Hampshire District Health Authorities. SUBJECTS--54 children aged 0-4 years who had leukaemia or non-Hodgkin''s lymphoma diagnosed during 1972-89, who were born in the study area and were resident there when cancer was diagnosed. Six controls were selected for each case: four from hospital delivery registers and two from livebirth registers maintained by the NHS central register. Controls were matched for sex, date of birth (within six months), and area of residence at birth and time of diagnosis. MAIN OUTCOME MEASURES--Parents'' employment by the nuclear industry and exposure to ionising radiation at work. RESULTS--Five (9%) of the 54 cases and 14 (4%) of the 324 controls had fathers or mothers, or both, who had been employed by the nuclear industry (relative risk 2.2, 95% confidence interval 0.6 to 6.9). Nuclear industry employees who work in areas where exposure to radiation is possible are given film badges to monitor their exposure to external penetrating ionising radiation. Three fathers of cases and two fathers of controls (and no mothers of either) had been monitored in this way before their child was conceived (relative risk 9.0, 95% confidence interval 1.0 to 107.8). No father (of a case or control) had accumulated a recorded dose of more than 5 mSv before his child was conceived, and no father had been monitored at any time in the four years before his child was conceived. A dose-response relation was not evident among fathers who had been monitored. CONCLUSIONS--These results suggest that the children of fathers who had been monitored for exposure to external penetrating ionising radiation in the nuclear industry may be at increased risk of developing leukaemia before their fifth birthday. The finding is based on small numbers and could be due to chance. If the relationship is real the mechanisms are far from clear, except that the effect is unlikely to be due to external radiation; the possibility that it could be due to internal contamination by radioactive substances or some other exposure at work should be pursued. The above average rates of leukaemia in the study area cannot be accounted for by these findings.     

Perinatal characteristics in relation to incidence of and mortality from prostate cancer.

OBJECTIVE--To test the hypothesis that factors causing morbidity and mortality from prostate cancer may operate in utero. DESIGN--Matched case-control study of singleton men born between 1874 and 1946 at one hospital. SETTING--Uppsala University Hospital. SUBJECTS--250 patients with prostate cancer and 691 controls, including 80 patients who died from prostate cancer and their 196 matched controls. MAIN OUTCOME MEASURES--Mother''s age at menarche, parity, pre-eclampsia or eclampsia before delivery, age at delivery and socioeconomic status; case or control''s birth length and weight, placental weight, prematurity derived from gestational age, and presence of jaundice. RESULTS--Both pre-eclampsia (odds ratio 0, 95% confidence interval 0 to 0.71) and prematurity (0.31, 0.09 to 1.04) were inversely associated with incidence of prostate cancer. Among subjects born full term, placental weight, birth weight, and ponderal index (weight/height 3) showed non-significant positive associations with prostate cancer incidence, and stronger associations with mortality. CONCLUSION--Prenatal exposures that are likely correlates of pregnancy hormones and other growth factors are important in prostate carcinogenesis and influence the natural course as well as the occurrence of this cancer.     

Risk of schizophrenia in adults born after obstetric complications and their association with early onset of illness: a controlled study.

OBJECTIVE--To determine whether obstetric complications occur to excess in the early histories of individuals who go on to develop schizophrenia when compared with controls, and to seek clinical correlates of any such excess. DESIGN--Contemporaneous maternity hospital records were identified and extracted verbatim, and these extracts evaluated for obstetric complications by two independent assessors who were blind to subjects'' status. SUBJECTS--65 patients having an ICD-9 diagnosis of schizophrenia, the records of the previous same sex live birth being deemed to be those of a control subject. MAIN OUTCOME MEASURE--Presence of one or more obstetric complications recorded in maternity notes of patients and controls. RESULTS--When two recognised scales for specifying obstetric complications were used the patients with schizophrenia were significantly more likely than controls to have experienced at least one obstetric complication (odds ratio 2.44, 95% confidence interval 1.08 to 6.03). Patients also showed a greater number and severity of and total score for obstetric complications, fetal distress being the only complication to occur to significant individual excess (present in five (8%) patients, absent in controls). There was a marked sex effect, male patients being more vulnerable (odds ratio 4.24, 1.39 to 12.90) to such complications. Obstetric complications in patients were unrelated to family history or season of birth but were associated with a significantly younger age at onset of illness (mean difference--4.5 years,--1.2 to--7.8 years). CONCLUSIONS--Patients with schizophrenia, particularly males, have an excess of obstetric complications in their early developmental histories, and such complications are associated with a younger age at onset of their disease. Though the data are not conclusive, they also suggest that obstetric complications may be secondary to yet earlier events.     

Gonococcal Ophthalmia Neonatorum Despite Treatment with Antibacterial Eye-drops

Over a five-year period, 1964-8, 48 cases of gonococcal ophthalmia neonatorum were notified to the department of venereology in Glasgow. Thirty-seven babies were born in hospital and 11 at home. The conjunctivitis, usually recorded as a “sticky eye,” developed between 1 and 13 days of birth, 36 by the fourth day.Diagnosis by culture of Neisseria gonorrhoeae was delayed in some cases up to 30 days after the appearance of the signs for those born in hospital and 15 days for those born at home, usually because of the blind use of antibacterial eye-drops which produced temporary alleviation of the signs without eradicating the infection; chloramphenicol was noteworthy in this respect.A “sticky eye” will resolve without the use of antibacterial agents, ophthalmia neonatorum will not. When it is decided to use an antibacterial agent pretreatment conjunctival smears for immediate staining and swabs for culture should be taken and the case notified to the medical officer of health.Gonococcal ophthalmia is a preventable disease. In view of the obstetricians'' already heavily committed clinical work load there is need for venereologists to collaborate, on consultation and within the maternity hospitals wherever possible, in the screening of antenatal patients for candidiasis and trichomoniasis as well as for gonorrhoea. Some target groups, those with a pathological vaginal discharge or with certain adverse social factors, warrant more thorough investigation, while all those treated require further examination to ensure cure.     

Outcome of breech delivery at term.

OBJECTIVE--To compare neonatal mortality and morbidity in term infants presenting by the breech and delivered vaginally or by caesarean section. DESIGN--Population based comparison of outcomes. Data derived from the St Mary''s maternity information system. SETTING--North West Thames Regional Health Authority, 1988-90. SUBJECTS--3447 singleton fetuses presenting by the breech at term. MAIN OUTCOME MEASURES--Intrapartum and neonatal mortality, low Apgar scores, intubation at birth, and admission to special care baby units. RESULTS--After the exclusion of babies with congenital anomalies the incidence of intrapartum and neonatal death associated with vaginal birth was 8/961 (0.83%) compared with 1/2486 (0.03%) in babies born by caesarean section (relative risk 20, 95% confidence interval 2.5 to 163). The numbers of low Apgar scores and neonatal intubation were doubled in babies born vaginally or by emergency caesarean section compared with those delivered by elective operation. CONCLUSIONS--The good neonatal outcome associated with elective caesarean delivery of the term breech fetus may influence the decision of women and their obstetricians about mode of delivery.     

Fourth goal of perinatal medicine.

Reduction in maternal mortality, infant mortality, and infant morbidity have been successively the goals of perinatal medicine. The fourth is to reduce bonding failure. In July 1978 a preventive service was started in the John Radcliffe Maternity Hospital. A twice-weekly round is made. Midwives refer families who cause them concern. In the first year the referral rate ws 20.5 per 1000 liveborn babies. The referred sample differed from the hospital population in terms of maternal psychiatric history, marital state and babies'' admission to special care. The main reasons for referral were: doubt about parenting ability (27%), psychiatric history (15%), disturbed behaviour in hospital (14%), and diffuse social and medical problems (17%). Long-term care was needed for only 14% of families. At their first birthdays, six babies were placed away from their natural parents; the sample had had a slightly higher than expected admission rate to hospital; the distribution of weights did not differ from the expected; doctors and health visitors were still concerned about one-quarter of the families. Seven cases of screening failure were found among those not referred to our service, but only one was seriously abused. No child referred in the first year has been seriously neglected or abused.     

Family Planning in the Hospital Setting

Although the availability of oral contraceptives and the development of improved intrauterine contraceptive devices have greatly increased the general utilization of family planning services, there are still great segments of our population which are not yet reached, especially in the economically deprived areas. Since over 98 percent of all obstetrical deliveries now occur in hospitals, it seems logical that it is on hospital maternity services that these deficiencies might often be best overcome. Although this is primarily a medical problem, the use of paramedical personnel can greatly augment the physician''s practice in these areas. Family planning services should be an integral part of comprehensive maternity care, not alone in the physician''s office but also in the hospital setting.     

A case-control study of maternal knowledge of malnutrition and health-care-seeking attitudes in rural South India.

INTRODUCTION: In India, approximately 20 percent of children under the age of four suffer from severe malnutrition, while half of all the children suffer from undernutrition. The contributions of knowledge and attitudes of nutrition-conscious behaviors of the mothers to childhood malnutrition has been unclear. The purpose of this study was to explore maternal knowledge of the causes of malnutrition, health-care-seeking attitudes and socioeconomic risk factors in relation to children''s nutritional status in rural south India. METHODS: A case-controlled study was conducted in a rural area in Tamil Nadu, India. Thirty-four cases and 34 controls were selected from the population of approximately 97,000 by using the local hospital''s list of young children. A case was defined as a mother of a severely malnourished child under four years of age. Severe malnutrition was defined as having less than 60 percent of expected median weight-for-age. A control had a well-nourished child and was matched by the location and the age of the child. Interviews obtained: (1) socioeconomic information on the family, (2) knowledge of the cause of malnutrition and (3) health-care-seeking attitudes for common childhood illnesses, including malnutrition. RESULTS: Poor nutritional status was associated with socioeconomic variables such as sex of the child and father''s occupation. Female gender (OR = 3.44, p = .02) and father''s occupation as a laborer (OR = 2.98, p = .05) were significant risk factors for severe malnutrition. The two groups showed a significant difference in nutrition-related knowledge of mild mixed malnutrition (OR = 2.62, p = .05). No significant difference was apparent in health-care-seeking attitudes. Based on their traditional beliefs, the mothers did not believe that medical care was an appropriate intervention for childhood illnesses such as malnutrition or measles. DISCUSSION: The results suggested that the gender of the child and socioeconomic factors were stronger risk factors for malnutrition than health-care availability and health-care-seeking attitudes. The father''s occupation was a more accurate indicator for malnutrition than household income. These results suggest a need for intensive nutritional programs targeted toward poor female children and their mothers.     

Your child is dead.

OBJECTIVE--To determine parent''s views on how death of their children should have been handled. DESIGN--Retrospective questionnaire survey of parents who had experienced death of their child. SETTING--Charitable organisation of bereaved parents. SUBJECTS--150 bereaved parents, all members of the organisation, of whom 120 (80%) participated voluntarily in the study. MAIN OUTCOME MEASURES--Child''s age; date and cause of death; details of person breaking the news and handling of the interview; time parents spent with dead child, their attitude to requests for organ donation, and follow up support received. RESULTS--122 children''s deaths were described; the largest single group was due to road traffic accidents, 16 were suicides, and eight were murders. Twice as many interviews were rated as sympathetically or reasonably handled as badly or offensively handled (68 v 34). The interview ratings depended on the sensitivity and personal skills of the interviewers rather than on their previous contact or professional position; police were rated as more sympathetic than doctors and nurses. Of 109 respondents, 81 had seen their child''s body, 44 of whom thought that sufficient time had been denied. Of the 28 parents who did not see the body, 17 subsequently stated their regret. In 82 parents organ donation had not been discussed. Only 16 parents recorded any follow up support from hospital staff and very few support at the time. CONCLUSIONS--The consistency of the responses suggests a serious need to revise the in service training and education of the police and health professionals in their approach to informing of death; organ donation should be discussed sensitively and parents allowed time with their dead child with fewer restrictions.     

Maternal BMI and country of birth as indicators of childhood obesity in children of Mexican origin

Objective: The goal of this study was to evaluate the relationship between maternal and childhood BMI at baseline in a group of 5‐ to 18‐year‐old children and their mothers, all of whom were of Mexican origin, low socioeconomic status, and enrolled in a cohort study in Houston, TX. Research Methods and Procedures: Using data from 438 mother‐child dyads residing in the same household, we completed logistic regression analyses to determine maternal factors associated with the child being overweight or at‐risk‐for‐overweight, after adjusting for the child's gender, age, and level of physical activity and other maternal confounders. Results: Almost one‐half of the boys and girls (47% and 44%, respectively) were either overweight or at‐risk‐for‐overweight. Obese mothers were twice as likely to have an overweight and/or at‐risk‐for‐overweight child compared with normal‐weight mothers. Women born in the U.S. were twice as likely to have an overweight and/or at‐risk‐for‐overweight child compared with women born in Mexico. In addition, women with less than a high school education were twice as likely to have an overweight child compared with their more educated peers. Discussion: The high prevalence of overweight or at‐risk‐for‐overweight among Mexican‐origin children of low socioeconomic status suggests a continued need to develop and implement culturally sensitive preventive interventions for this minority population. Our data also suggest a need to tailor such interventions particularly for children of obese mothers and those born in the U.S.     

Effects of childhood cancer on long-term survivors and their families.

Problems experienced by families of long-term survivors of acute lymphatic leukaemia and Wilms''s tumour were investigated to find out the best way of using limited resources to improve management of such patients. All patients had received treatment at Alder Hey Children''s Hospital, and all had completed treatment at least two years before the study. A social worker interviewed the parents of each child. The results showed that various aspects of management needed improvement, including: information given to parents at diagnosis of their child''s illness and during subsequent treatment; continuity of care and multidisciplinary teamwork among those caring for the child; greater understanding by school teachers that such children have the same educational needs as others; wider communication by hospital staff with the child''s other relatives, particularly grandparents; financial help for parents; and marital counselling. To help implement these proposals full-time social workers were attached to the hospital. Preliminary results were encouraging, though it is too early to evaluate the long-term effects of the changes.     

Methods and basic data of case-control study of leukaemia and lymphoma among young people near Sellafield nuclear plant in West Cumbria.

OBJECTIVE--To examine whether the observed excess of childhood leukaemia and lymphoma near the Sellafield nuclear plant is associated with established risk factors or with factors related to the plant. DESIGN--A case-control study. SETTING--West Cumbria health district. SUBJECTS--52 Cases of leukaemia, 22 of non-Hodgkin''s lymphoma, and 23 of Hodgkin''s disease occurring in people born in the area and diagnosed there in 1950-85 under the age of 25 and 1001 controls matched for sex and date of birth taken from the same birth registers as the cases. MAIN OUTCOME MEASURES--Antenatal abdominal x ray examinations, viral infections, habit factors, proximity to and employment characteristics of parents at Sellafield. RESULTS--Ascertainment of cases through multiple sources was as complete as possible, and the diagnosis was established for nearly all cases from hospital records and by independent pathological review when suitable material (60% (58) of cases) was available. Identification and tracing of the parents of cases and controls enabled questionnaires to be forwarded to 730 (66%), and 467 (64%) of the questionnaires were returned completed. Obstetric records were located for 481 (44%) of the relevant births, more frequently in recent years. Linkage of study subjects to the Sellafield workforce file enabled dates of employment and records on external doses of whole body ionising radiation to be obtained. Concordance of information from duplicate sources (when available) was reasonably high with no indications of bias. CONCLUSION--Overall the collected data were sufficiently reliable for detailed analysis and careful interpretation.     

Outbreaks of salmonella infection in hospitals in England and Wales 1978-87.

A total of 248 outbreaks of salmonella infection in hospital affecting over 3000 patients and 110 associated deaths were ascertained in England and Wales in 1978-87, compared with 522 outbreaks of salmonella in 1968-77. The largest reduction was found in outbreaks from children''s units and maternity units. Fifty seven (24%) outbreaks were considered to be due to foodborne salmonellosis, and 70 (30%) were reported as person to person spread of the infection. The psychiatric hospital was the type of hospital in which foodborne outbreaks most often occurred, but the risk of being affected in an outbreak not due to food seemed to be highest in maternity units. Better control of infection and better surveillance should lead to earlier investigation and control of outbreaks.     

Offspring of male and female parents with thalidomide embryopathy: birth defects and functional anomalies

BACKGROUND: The aim of the study was to evaluate congenital malformations and functional anomalies in the offspring of Swedish parents with thalidomide embryopathy (TE). METHODS: Sixty-four children (29 girls, 35 boys) with ages ranging from 0-18 years, born to 34 Swedish parents (14 women, 20 men) with TE, were studied. Data on malformations and dysfunction were collected from medical records at maternity and child healthcare units, delivery units, hospitals, outpatient clinics and schools. RESULTS: Five children had both a mother and father with TE, 23 had a mother suffering from TE, and in 36 children the father had TE. One girl had a major malformation consisting of pulmonary stenosis, and single cases of minor physical features and positional deformities were observed. One boy had autism. Four children were born preterm, all to a TE mother. One child died within 24 hr after birth. Seven spontaneous abortions were registered, five of them in TE mothers. The cesarian section rate was 39% among the TE mothers, compared to 14% among the non-TE mothers. CONCLUSIONS: Malformations or functional anomalies similar to those typical for TE were not found in this group of children born to Swedish parents with TE. Cesarian sections were more frequently performed in TE mothers, partly because of pelvic and uterine malformations.     

Breast-feeding and respiratory syncytial virus infection.

The pattern of breast-feeding in 127 infants admitted to hospital with respiratory syncytial virus infection was compared with that in 503 age-matched controls. Thirty per cent of children with infection had been breast-fed compared with 49% of controls. The approximate relative risk of being admitted to hospital with respiratory syncytial virus infection if not breast-fed was 2.2. Several other factors were also considered, including an assessment of maternal care and home environment; the mother''s age, marital state, and smoking habits; the number of siblings; and gestation. Adverse factors were all associated with an increased risk of admission with infection, but breast-feeding still appeared to provide protection after controlling for these other factors in turn. These findings provide further support for encouraging mothers to breast-feed their infants and should prompt further studies into the immune status of mothers and into the nature of the protective factors in their breast milk.     

Was Young's syndrome caused by exposure to mercury in childhood?

OBJECTIVE--To determine whether the incidence of chronic sinusitis, bronchitis, or bronchiectasis in men with obstructive azoospermia (Young''s syndrome) has fallen in men born after 1955 when calomel (mercurous chloride) was removed from teething powders and worm medication in the United Kingdom. DESIGN--A prospective study of aetiological factors in subfertile men with epididymal obstruction operated on between 1975 and 1993. SETTING--Central London. SUBJECTS--274 men with obstructive azoospermia undergoing epididymovasostomy; date of birth was recorded and illness in childhood, persistent nasal or respiratory symptoms, and previous urinary or genital infection were asked about. MAIN OUTCOME MEASURE--Site of epididymal block and association with possible aetiological factors, related to date of birth. RESULTS--146 men had hold up in the head of the epididymis (capital blocks): 119 (82%) had Young''s syndrome, and 11 gave a definite history of pink disease (mercury intoxication) in childhood. 128 had obstruction lower down towards the tail of the epididymis (caudal blocks): 64 (50%) had a history of genital or urinary infection, and only three had Young''s syndrome; none had had pink disease. The incidence of Young''s syndrome fell significantly from 114 (50%) of 227 men born up to 1955 to eight (17%) of 47 men born since then. CONCLUSIONS--The decline in incidence of Young''s syndrome in those born after 1955 is similar to that observed with pink disease, suggesting that both conditions may have had a similar aetiology--mercury intoxication.
