ABSTRACT
Background: There is great variability between centers regarding contrast injection protocols. They should only be injected if they can provide useful information for diagnosis with the necessary and sufficient quantity of iodine. We wanted to know through this study if the use of iodinated contrast media is optimised in abdominal CT scans performed for cancer assessment in Lomé. Materials and Methods: It was a cross-sectional, descriptive, and analytical study with a prospective collection over a period of 6 months in three CT units in Lomé. It involved abdominal CT scans performed for oncological evaluation. Data were reported as the mean ± standard deviation. The Pearson correlation coefficient, ANOVA, chi-square, and the Fisher test were used. Results: A total of 218 examinations were recorded. The female sex represented 56.88% of the patients. The mean age was 50.92 ± 15.78 years. The mean weight was 70.46 ± 15.23 kg. The mean BMI was 24.91 ± 5.32 kg/m2. The examinations were performed with a voltage of 120 kV in 195 cases (89.45%). The mean dose of injected iodine was 0.42 ± 0.09 gI/kg with a dose of 0.40 gI/kg at 80 kV and 0.45 gI/kg at 130 kV. The mean injection rate was 2.90 ± 0.34 mL/s. The mean injected volume was 83.19 ± 7.29 mL. The mean duration of the injection was 30.60 ± 7.39 s. The mean iodine delivery rate was 0.98 ± 0.17 gI/s. There was no saline injection in 152 cases (69.72%). Liver contrast enhancement was satisfactory in 94.5% of cases. There was a strong negative linear correlation between the dose of injected iodine and weight. Conclusions: Optimization guidelines for the use of iodinated contrast media are not always applied. Therefore, monitoring and benchmarking programmes for iodinated contrast injection protocols that involve all radiology personnel should be implemented.
ABSTRACT
The association of breast cancer and abscess is rare in daily practice. The authors report a short series of 3 cases of cancer of the breast in nonlactating women presented as breast abscess, reviewing aspects in radiology (ultrasound and mammography), correlating them with the histopathology findings and the bacteriological profile of the isolated germs.
ABSTRACT
Objectifs : Cette etude etait menee dans le but de determiner la frequence des demandes de radiographie standard du thorax dans le diagnostic de la toux; de decrire les differentes lesions radiographiques elementaires observees et de repertorier les differentes etiologies mises en evidence. Patients et methode : Il s'est agi d'une etude prospective de dix (10) mois portant sur 981 patients adultes recus pour radiographie du thorax dans le cadre de la toux. Les cas pathologiques diagnostiques nous ont permis d'etablir le diagnostic etiologique et la correlation entre les lesions radiographiques et les etiologies retenues. Resultats : La frequence de prescription de la radiographie du thorax dans le cadre de la toux etait de 17;02%. L'age de nos patients a varie de 18 a 87 ans avec 40 ans comme age moyen. Une predominance feminine s'etait degagee de notre etude 504 femmes contre 477 hommes. Les resultats etaient pathologiques dans 63;10% des cas (n=619). Les lesions pulmonaires de siege apical (45;88%; n=284) etaient dominantes. Les lesions elementaires se sont presentees en majorite sous forme d'opacites (73;83%; n=457). Les syndromes mixte (34;89%); alveolaire (21;97%) et interstitiel (18;09%) etaient les plus dominants. La tuberculose (50;46%; n=218) et la pneumonie communautaire (23;38%; n=101) etaient les principales etiologies repertoriees alors que le pneumothorax (01;39%; n=06) et le cancer broncho-pulmonaire (0;46%; n=02) etaient les moins representes. Toutes les lesions elementaires ont ete retrouvees dans la tuberculose avec une predominance des opacites micronodulaires (22;02%; n= 48) suivies des opacites alveolo-interstitielles (13;76%; n= 30). Les opacites systematisees avec bronchogramme aerien ont ete caracteristiques de la pneumonie dans 51;49% des cas (n= 52). Conclusion : La radiographie pulmonaire est d'un grand apport dans le diagnostic de la toux chez l'adulte

Cervicogenic headaches are a nosologic entity recently recognized. In our common practice, we have noticed a relative frequency of the atlas spina-bifida occulta during the brain CT scan realized for headaches without cranio-encephalic causes or any other anomaly of the upper cervical region. The aim of this study was to determine a possible connection between cervicogenic headaches (CEH) and atlas spina-bifida occulta. A 2 years prospective and descriptive study in 20 black patients having an atlas spina-bifida occulta diagnosed with a brain CT scan. The mean age of the patients was 43.17 ± 18.35 years (extremes: 24 and 72 years). A light female predominance was noticed (sex-ratio = 1.5). The frequency of symptomatic spina-bifida was 1.72 % (17 cases). The mean age at onset was 31.84 years. The pain was sub-occipital in 14 cases, occipital in 8 cases, bilateral in 12 cases and unilateral in 5 cases. The mean duration of the attacks was 72 ± 24 h and the pain intensity was moderate (16 cases); mean and range were 3.6 and 3-6. The frequency of attacks varied between 1 per 7 months (n = 2) and 2 per week (n = 1) in those with non-daily headache. One attack per 5-7 weeks was the most commonly occurring attack frequency. The pain was reproduced by the pressure of the occipital region or upper cervical in 15 cases. The mean number of criteria was five and there was a strong positive correlation between criteria and CEH (χ (2) = 45.57; V = 0.62). The associated signs were photophobia and nausea in one case each. Indomethacin, Ergotamine and/or Sumatriptan were without any antalgic effect in 16 cases. Pain ceased after an anesthetic blockade of C2 (16 cases). The results show that atlas spina-bifida occulta is not involved in CEH pure form genesis. On a small sample, the atlas spina-bifida seems to be a cause of CEH associated with headache and disorders of the neck.
