EFFECTIVE DOSE AND RISK ESTIMATES IN ADULT PATIENTS FROM FOUR RADIOLOGICAL PROCEDURES EXTRAPOLATED OVER TWO POPULATIONS AT SOME SELECTED CENTERS IN LAGOS STATE, NIGERIA.

In this study, risk of exposure to adult patients in some common radiological procedures was estimated at selected diagnostic centers in Lagos State, Nigeria using estimated average effective doses. The results showed that pelvis lateral (LAT) examination with the lowest estimated mean effective dose level (2.61) recorded the highest probability of cancer incidence and mortality occurrences, while lumbar anteroposterior (AP) had the lowest (3.61). A high sum total of probability of fatal cancers and the total weighted probability of non-fatal cancer in a single exposure to low-dose ionizing radiation were recorded in pelvic procedure among others. Also, a high-percentage mortality increase of solid cancers was recorded in chest PA examination (53.7%), while the lowest was in lumbar spine radiography (with lumbar AP = 0.14%, lumbar LAT = 0.15%). The data obtained suggested the possibility of having higher percentage mortality and cancer-related incidence in the chest.

Outcome of non-operative management of femoral shaft fractures in children.

BACKGROUND: Femoral shaft fractures are common injuries in childhood. There is paucity of information on their presentation and outcome of the available treatment methods in the African population. This study evaluated the outcome of non-operative methods of treatment of femoral shaft fractures in our centre. PATIENTS AND METHODS: A retrospective review of the database of children aged 14 years and below with femoral shaft fractures treated non-operatively over a 10-year period. RESULTS: A total of 134 patients with 138 fractures met the study criteria. This consisted of 71 boys (mean age = 6.1 years ± SD) and 63 girls (mean age = 6.5 years ± SD). Pedestrian vehicular accident was the most common cause of femoral shaft fractures in the study population. The midshaft was the most common site of fractures. There were associated injuries to other parts of the body (especially head injury) in 34.3% of the patients. The commonest mode of treatment was skin traction only (87.7%). The mean time to fracture union was 4.9 weeks ± SD (range = 3-15 weeks). The mean length of hospitalisation was 6.7 weeks ± SD (range = 5 days-11 weeks). There was a fairly strong positive correlation between the length of hospitalisation and the presence of associated injuries, especially head injury, upper limb fractures and bilaterality of the fractures. The mean total cost of treatment was #7685 (Naira) or $51.2 (range = $14.2-$190). At the last follow up, 97.8% of the fractures united without significant angulation or shortening. CONCLUSION: The outcome of non-operative treatment of femoral shaft fractures in our setting is comparable to the results of other workers. Methods of treatment that shorten the length of hospitalisation without unduly increasing cost should be encouraged.

Femoral bifurcation with ipsilateral tibia hemimelia: early outcome of ablation and prosthetic fitting.

Femoral bifurcation and tibia hemimelia are rare anomalies. Hereby, we present a case report of a 2-year-old boy who first presented in our orthopedic clinic as a 12-day-old neonate, with a grossly deformed right lower limb from a combination of complete tibia hemimelia and ipsilateral femoral bifurcation. Excision of femoral exostosis, knee disarticulation and prosthetic fitting gives satisfactory early outcome.

Evaluation of the roll over test as predictor of gestational hypertension in African women.

Fifty-six primigravid women at 28-32 weeks gestation were studied prospectively to assess the roll over test (ROT) as a predictor of gestational hypertension in African women. Blood pressures were measured continuously in the supine and left lateral positions using an automated accutor machine. ROT was positive in only two women (3.6%). These two women later developed gestational hypertension but so did 18 others who had negative ROT. Measures that may be useful in increasing the predictive value of the ROT in these women are suggested.

Does standing up improve the predictive value of the supine pressor test for gestational hypertension?

Fifty-six primigravid women at 28-32 weeks' gestation were studied prospectively to compare the roll-over test with the stand-up pressor test in the prediction of gestational hypertension. Blood pressures were measured in the different positions continuously using an automated machine. Twenty patients developed gestational hypertension; two of these were accurately predicted by roll-over test and six by stand-up pressor test (P less than .001). However, there was no significant difference between the tests in the rates of false negatives, specificity, and negative and positive predictive values. Concomitant measurement of blood pressures in the standing position may increase the sensitivity of the roll-over test for the prediction of gestational hypertension.
