The epidemiology of trematode infections in cattle was investigated within highland and lowland areas of Iringa Rural District, in southern Tanzania. Fecal samples were collected from 450 cattle in 15 villages at altitudes ranging from 696 to 1800 m above the sea level. Freshwater snails were collected from selected water bodies and screened for emergence of cercariae. The infection rates in cattle were Fasciola gigantica 28·2%, paramphistomes 62·8% and Schistosoma bovis 4·8%. Notably, prevalence of trematode infections in cattle was much higher in highland (altitude > 1500 m) as compared with lowland (altitude < 1500 m) areas and was statistically significant (P-value = 0·000) for F. gigantica and paramphistomes but not for S. bovis. The snails collected included Lymnaea natalensis, Bulinus africanus, Bulinus tropicus, Bulinus forskali, Biomphalaria pfeifferi, Melanoides tuberculata and Bellamya constricta with a greater proportion of highland (75%) than lowland (36%) water bodies harbouring snails. Altitude is a major factor shaping the epidemiology of F. gigantica and paramphistomes infections in cattle in Iringa Rural District with greater emphasis upon control needed in highland areas.
During a longitudinal study investigating the dynamics of malaria in Ugandan lakeshore communities, a consistently high malaria prevalence was observed in young children despite regular treatment. To explore the short-term performance of artemether-lumefantrine (AL), a pilot investigation into parasite carriage after treatment(s) was conducted in Bukoba village. A total of 163 children (aged 2–7 years) with a positive blood film and rapid antigen test were treated with AL; only 8·7% of these had elevated axillary temperatures. On day 7 and then on day 17, 40 children (26·3%) and 33 (22·3%) were positive by microscopy, respectively. Real-time PCR analysis demonstrated that multi-species Plasmodium infections were common at baseline, with 41·1% of children positive for Plasmodium falciparum/Plasmodium malariae, 9·2% for P. falciparum/ Plasmodium ovale spp. and 8·0% for all three species. Moreover, on day 17, 39·9% of children infected with falciparum malaria at baseline were again positive for the same species, and 9·2% of those infected with P. malariae at baseline were positive for P. malariae. Here, chronic multi-species malaria infections persisted in children after AL treatment(s). Better point-of-care diagnostics for non-falciparum infections are needed, as well as further investigation of AL performance in asymptomatic individuals.
Here we revisit and reinterpret the original study in which the so-called
‘Maudsley (London) model’ of family therapy was compared with individual
therapy for anorexia nervosa. Family therapy was more effective in
adolescents with a short duration of illness. However, this is only part of
the story. A later study describing the 5-year outcome contains important
information. Those adolescents randomised to family therapy achieved a
better outcome 5 years later. Moreover, the group with an onset in
adolescence but who had been ill for over 3 years had a poor response to
both family and individual therapy, suggesting that unless effective
treatment is given within the first 3 years of illness onset, the outcome is
poor. We examine other evidence supporting this conclusion and consider the
developmental and neurobiological factors that can account for this.
Lord Owen has alerted us to the dangers of ill health in heads of government, especially if they strive to keep their illnesses secret. The description of the hubris syndrome is still at an early stage but Owen has provided psychiatrists and other physicians with useful guidance on how to recognise its appearance in persons who hold positions of power. He has also provided advice to doctors caring for such persons.
Silvio Benaim died on 10 January 2008 at Highgate Nursing Home, London, after a long illness. He was a senior consultant psychiatrist at the Royal Free Hospital since 1968, having been a consultant at Halliwick Hospital from 1959. He retired from the National Health Service (NHS) in 1983 but continued his private practice at the Charter Nightingale Clinic until 2004.
