The Angiographic Findings in a Haemophilic Pseudotumour of Bone

The angiographic findings in a patient with haemophilic pseudotumour of the femur are presented. The examination showed the position of the displaced femoro-poplited vessels, enabling these structures to be avoided at operation. Under anti-haemophilic globulin cover no complications occurred. It is suggested that angiography may be safely employed provided the coagulation defect is controlled. The examination may be useful in differentiating other bone lesions and in defining more clearly the extent of a haemophilic pseudotumour.     

Concentrations of selective metabolites of organophosphorus pesticides in the United States population

We report population-based concentrations (stratified by age, sex, and composite race/ethnicity variables) of selective metabolites of chlorpyrifos (3,5,6-trichloro-2-pyridinol; TCPY), chlorpyrifos methyl (TCPY), malathion (malathion dicarboxylic acid; MDA), diazinon (2-isopropyl-4-methyl-6-hydroxypyrimidine; IMPY), methyl parathion (para-nitrophenol; PNP), and parathion (PNP). We measured the concentrations of TCPY, MDA, IMPY, and PNP in 1997 urine samples from participants, aged 6-59 years, of the National Health and Nutrition Examination Survey, 1999-2000. We detected TCPY in more than 96% of the samples tested. Other organophosphorus pesticide metabolites were detected less frequently: MDA, 52%; IMPY, 29%; and PNP, 22%. The geometric means for TCPY were 1.77 microg/L and 1.58 microg/g creatinine. The 95th percentiles for TCPY were 9.9 microg/L and 8.42 microg/g creatinine. The 95th percentiles for MDA were 1.6 microg/L and 1.8 microg/g creatinine. The 95th percentiles for IMPY and PNP were 3.7 microg/L (3.4 microg/g creatinine) and 5.0 microg/L (4.2 microg/g creatinine), respectively. Multivariate analyses showed that children aged 6-11 years had significantly higher concentrations of TCPY than adults and adolescents. Similarly, adolescents had significantly higher TCPY concentrations than adults. Although the concentrations between sexes and among composite racial/ethnic groups varied, no significant differences were observed.     

Prevalence of different skin conditions in an outpatients' setting in north-western Nigeria

BACKGROUND: Information on skin diseases in north-western Nigeria is scanty. We therefore conducted a prospective survey of 2611 new patients seen between August 1999 and July 2001 at the consultant medical/dermatology clinics of Usmanu Danfodiyo University Teaching Hospital, Sokoto, Nigeria. METHODS: The personal bio-data of all consecutive patients with skin diseases were documented. They were examined and the diagnoses, which were based on the history of presentation and physical examination, were recorded. Bacteriologic, mycologic, and histologic confirmations were obtained as appropriate. RESULTS: Seven hundred and forty-six patients (28.6%) had skin diseases. There were 407 male and 339 female patients aged between 0.17 and 90 years; the median age was 27 years. The median ages for male and female patients were 28 and 25 years, respectively. There were 900 skin diseases seen in the 746 patients. The majority of skin diseases were found amongst the younger age group, which represented over 85% of the patients. Infectious and parasitic skin diseases accounted for 44.4% of cases; eczema, acne, papulosquamous, and pigmentary skin disorders were observed in 14.1%, 7.0%, 6.4%, and 6.0% of cases, respectively. CONCLUSIONS: Preventable skin diseases are common in north-western Nigeria and predominantly affect individuals in the highly productive age group. Health education is therefore necessary to curb their spread, reduce the associated morbidity, and improve the health status of the population. A concerted effort should be made to train health workers in the diagnosis and treatment of the more common dermatologic conditions.     

Ancestry reported by white adults with cutaneous melanoma and control subjects in central Alabama

Background  

We sought to evaluate the hypothesis that the high incidence of cutaneous melanoma in white persons in central Alabama is associated with a predominance of Irish and Scots descent.

Suspected poisoning in children. Study of the incidence of true poisoning and poisoning scare in a defined population in North East Bristol

The distinction between true and suspected poisoning in children has not been made clear in previous work on childhood poisoning. A study of suspected poisoning in children under 15 years of age in a defined population of North East Bristol from November 1970 to July 1973 carried out by the Health Education Council Medical Research Division included 53,000 child-years at risk. The number of suspected poisonings was 3-4/1000 population aged under 15 years per year, with a higher incidence in younger age groups. Detailed investigation of the circumstances of the accidents carried out by a multidisciplinary team showed that at least 65%, and possibly as many as 78% were poisoning scares and not true poisoning. The evidence used by the casualty doctor and by the parents to diagnose poisoning was explored, and in many cases was circumstantial. Children with fathers in nonmanual occupations were over-represented. This may reflect differences in patterns of utilization behaviour rather than true differences in incidence.
