How much do patients in Blantyre, Malawi know about antibiotics and other prescription only medicines?

Introduction This qualitative and quantitative exploratory study was conducted to assess patients’/customers’ knowledge, beliefs and practices about antibiotics and other prescription only medication (POM) in 10 community pharmacies in Blantyre, Malawi. Method 5 out of 10 pharmacies were selected by simple random sampling and 54 participants attending the selected pharmacies were interviewed. Results The major antibiotic drugs frequently requested without a doctor’s prescription were Bactrim (Cotrimoxazole) and amoxicillin. Knowledge of these medicines was attributed to the patients’ previous medical conditions and doctor’s prescription. However this knowledge does not extend to understanding of proper therapeutic indications and dosage regimens for antibiotic therapy. The majority (30 out of 54 participants) did not know about the importance of completing a prescribed course of antibiotics. All 54 participants believed in the efficiancy of antibiotics. Conclusion Study participants had wide range of knowledge about antibiotics and other POM from hospital, but the majority had limited knowledge regarding clinical indications and correct dosage schedules.

Analysis of only 0-1 min clip or 1-4 min Clip for focal liver lesions during contrast-enhanced ultrasonography

Purpose: To evaluate the reliability of analysis of only 0-1min clips and 1-4min clips versus the entire clips in performing contrast-enhanced ultrasonography (CEUS) of focal liver lesions (FLLs). Methods: Contrast-enhanced ultrasonography (CEUS) examinations of 43 single FLLs were performed. All clips were analyzed in three ways, the entire clips, 0-1 min clips and 1-4 min clips, benign or malignant diagnosis and pathological diagnosis of each FLL were concluded by the three ways subsequently. Results: The results of correct diagnosis were assessed using Chi-square test. There was no difference with regard to benign or malignant diagnosis, between 0-1min clips and the entire clips, or between 1-4 min clips and the entire clips (p = 0.243 and p = 0.747, respectively). Moreover, no significant differences in pathological diagnosis existed between 0-1min clips and the entire clips, and 1- 4min clips versus entire clips (p=0.808 and p = 0.808, respectively). No significant differences existed among CEUS entire clip, 0-1min clip and 1-4min clip in identifying FLLs, and based on which the diagnosis of two different FLLs during CEUS with only one injection of contrast agent can be available. Conclusion: Only 0-1min clips or 1-4 min clips can be used to instead of the entre clip in performing CEUS of FLLs.
