Presentation and outcome of 1107 cases of schistosomiasis from Africa diagnosed in a non-endemic country.

Schistosomiasis is found in a significant proportion of returning travellers and immigrants to Britain. This study is a retrospective review of 1107 consecutive cases of schistosomiasis from Africa diagnosed by microscopy or serology presenting to the Hospital for Tropical Diseases, London, UK. 50.4% of cases were asymptomatic. The most common symptom which resolved on treatment was tiredness. Serology was positive in 951 (86%), and ova seen in 45%. Urine dipstick testing was positive for blood in 21% and protein in 15%, with eosinophilia in 44%. In this population urine dipstick, full blood count and serology were all insufficient screening tools used alone. Among patients with full follow-up data 3 months or more after treatment with praziquantel, definite treatment failure occured in 4 of 271 (1.5%), restricting the analysis to those with ova seen at diagnosis. There was no significant difference in treatment failure between 1 and 3 days of treatment. Antibody level was the same or higher than at treatment in 55% of cases seen after about 3 months and 38% after 1 year, confirming it is probably of limited clinical use in detecting treatment failure.

Case reports: acute hookworm infection: an unusual cause of profuse watery diarrhoea in returned travellers.

We describe 3 returned travellers who developed profuse watery diarrhoea associated with marked blood eosinophilia. Delayed appearance of ova in stool samples caused difficulty in establishing diagnoses of acute hookworm infection. Low activity of ivermectin against hookworm resulted in failure of empiric treatment with this agent prior to parasitological diagnosis.

Blood pressure monitoring with home monitors versus mercury sphygmomanometer.

OBJECTIVE: To determine the accuracy of three automatic monitors (arm, wrist, finger) for blood pressure measurement manufactured by Omron compared with a standard mercury sphygmomanometer. PRIMRY END POINT: Difference in the mean blood pressure readings from each monitor; the secondary end point was difference in pulse readings. DESIGN: A single-visit, crossover trial tested each device twice on the left arm of each participant; the average of the two readings was recorded. The pulse readings from each monitor were also recorded. ANOVA was used to compare mean blood pressure readings and pulse readings from each device. RESULTS: A total of 55 persons (mean age 53 y; 36 women) met inclusion criteria and completed the study. The mean systolic and diastolic readings obtained from the electronic arm unit were comparable to the mercury readings (124.4/78.02 vs. 129.45/77.87 mm Hg, respectively; p > 0.05 for both readings). The mean results obtained from the wrist and finger monitors differed significantly from those of the mercury readings (145.44/89.58 and 113.94/69.07 mm Hg, respectively; p < 0.05 for both monitors compared with control). No difference was measured in the mean pulse readings between the comparisons (p = 0.72). The absolute difference in systolic and diastolic blood pressure readings from control varied the least wih the arm monitor. CONCLUSIONS: Compared with the mercury sphygmomanometer, the arm monitor was the most accurate in measuring blood pressure. The wrist and finger monitors resulted in statistically significant mean systolic and diastolic differences compared with the mercury sphygmomanometer.

The role of the nurse: extended or expanded?

The subject of role extension has been much debated, particularly in recent years as a result of changing healthcare policies, growing demands by nurses and the public, and arguments about the very nature of nursing itself. The recent media furore over the theatre sister who performed an appendectomy is but one example. This article will take account of recent trends and look at the different concepts of role extension and role expansion. How nursing can best adapt these roles to meet patients' needs will also be considered.

A study of 235 cases of human brucellosis in Sana'a, Republic of Yemen.

We studied the clinical characteristics of brucellosis among all patients with brucellosis referred to the Central Health Laboratory from the main hospitals in Sana'a during a 2-year period (1992-93) (235 adults and children). A history was taken from each patient and clinical examination, general laboratory tests and brucellosis laboratory tests carried out. The overall clinical picture of brucellosis in this study is very similar to that reported by other workers in this geographical area. Awareness of the presenting features and the realization that brucellosis should be part of the differential diagnosis of febrile patients with enlarged liver, spleen and lymph nodes will lead to an increasing index of suspicion for this disease.

Clinical supervision: making it happen.

When owned and governed by those who implement it, clinical supervision can become a living, breathing part of professional working life, and not just another ritual. A multidisciplinary team from Southampton explains.
