Abstract Background: Praziquantel (PZQ) is the standard treatment for Schistosomiasis in sub-Saharan Africa. However, there is evidence suggesting praziquantel treatment failure in Schistosome infections with associated potential renal impairment. The objective of this study was to determine the effect of three monthly doses of 60 mg/kg/day PZQ on schistosome egg count, liver and renal function during the treatment of urinary schistosomiasis in Ghana.Methods: A nested case-control study was designed from a cohort screened for schistosomiasis; 28 schistosomiasis positive cases by microscopy matched with 53 healthy controls by age and gender. The study population was urban dwellers from the Asokwa sub-metropolitan area, Kumasi in Ghana. Participants were within the age range of 6 to 30 years. We assessed S. haematobium egg counts in urine and its associated impact on liver and renal function at baseline, treatment and post-treatment phases. Results: Of the 28 cases and 53 controls, 78.6% and (81.1% were males respectively. Globulin levels before treatment was higher in cases [(36.92±1.46 vrs 27.88±1.49), p=0001] at pre-treatment but not at post-treatment [(35.35±1.28 vrs 37.26±1.77), p= 0.391]. Estimated cure rate was 42.9%, 46.4% and 96.4% after first, second and third dose respectively. Schistosome egg counts dropped significantly (p= 0.001) from before second dose to post-treatment. Similarly, levels of alanine aminotransferase (p=0.001), aspartate aminotransferase (p=0.028) and gamma glutamyl transferase (p=0.001) significantly declined towards post-treatment. Estimated glomerular filtration rate significantly improved from before second dose to post-treatment using both the Chronic Kidney Disease Epidemiology Program (p=0.001) and 4-variable Modification of Diet in Renal Disease (p=0.002) equations. Conclusion: Treatment of urinary Schistosoma hematobium infections with a repeated high monthly dose of 60 mg/kg of praziquantel for 3 months could be an effective and safe alternative for the current treatment option 40 mg/kg body weight.

AbstractBackgroundCadmium serves as a major pollutant in the environment and it has been documented for its widespread harmful effects. This study sought to investigate the prophylactic and the curative effects of aqueous and methanolic leaf extracts of Polyalthia longifolia against cadmium-induced hepatotoxicity in rats.MethodsAnimals in group I served as the normal control and administered distilled water only for 14 days, group II was administered cadmium (4 mg/kg/body weight) for 7 days, groups III and IV rats served as the prophylactic group and were pre-treated with P. longifolia aqueous and methanolic leaf extract for 7 days and then exposed to cadmium for another 7 days, serving as pre-treatment group, groups V, VI, VII, and VIII served as curative groups and were first exposed to cadmium for 7 days and then post-treated with 100 and 200 mg/kg body weight of aqueous extract and 100 and 200 mg/kg body weight of methanolic extract P. longifolia for another 7 days.ResultsPre- and post-treatment with both extracts of P. longifolia revealed a significant hepatoprotective ability by decreasing the alanine transaminase, alkaline phosphatase, aspartate transaminase, acid phosphatase, gamma glutamyl transferase enzymatic activities were elevated due to cadmium intoxication. Pre- and post-treatment with aqueous and methanolic extract of P. longifolia extract significantly decreased hepatic malondialdehyde levels, together with an improvement in the antioxidant status of superoxide dismutase, glutathione peroxidase, catalase, glutathione S-transferase, and reduced glutathione of rats exposed to cadmium. Histopathology examinations also confirm the above biochemical findings.ConclusionThe findings from this work suggested that P. longifolia may be beneficial in ameliorating the cadmium-induced hepatotoxicity and oxidative stress in rats.

Abstract During the 11th International Conference on Typhoid and Other Invasive Salmonelloses held in Hanoi, Vietnam, a number of papers were presented on the burden of disease, epidemiology, genomics, management, and control strategies for invasive nontyphoidal Salmonella (iNTS) disease, which is increasingly becoming an important public health threat in low- and middle-income countries, but especially in sub-Saharan Africa (sSA). Although there were minor variations in characteristics of iNTS in different settings (urban vs rural, country to country), it was observed that iNTS has gained greater recognition as a major disease entity in children younger than 5 years. Renewed efforts towards greater understanding of the burden of illness, detection and diagnostic strategies, and management and control of the disease in communities in sSA through the introduction of vaccines will be important.

Schistosomiasis is a disease caused by a flatworm parasite that infects people in tropical and subtropical regions of Sub-Saharan Africa, South America, China, and Southeast Asia. The reliance on just one drug for current treatment emphasizes the need for new chemotherapeutic strategies. The aim of this study was to determine the phenotypic effects of extracts and fractions of leaf and stem bark of Erythrophleum ivorense (family Euphorbiaceae), a tree that grows in tropical parts of Africa, on two developmental stages of Schistosoma mansoni, namely, postinfective larvae (schistosomula or somules) and adults. Methanol leaf and stem bark extracts of E. ivorense were successively fractionated with acetone, petroleum ether, ethyl acetate, and methanol. These fractions were then incubated with somules at 0.3125 to 100 μg/mL and with adults at 1.25 μg/mL. The acetone fractions of both the methanol leaf and bark of E. ivorense were most active against the somules whereas the petroleum ether fractions showed least activity. For adult parasites, the acetone fraction of methanol bark extract also elicited phenotypic changes. The data arising provide the first step in the discovery of new treatments for an endemic infectious disease using locally sourced African medicinal plants.

Spine metastatic disease is an increasingly common occurrence in cancer patients due to improved patient survival. Close proximity of the bony spinal column to the spinal cord limits many conventional treatments for metastatic disease. In the past decade, we have witnessed dramatic advancements in therapies, with improvements in surgical techniques and recent adoption of spine stereotactic radiotherapy techniques leading to improved patient outcomes. Multidisciplinary approaches to patient evaluation, treatment and follow-up are essential. Imaging plays an ever increasing role in disease detection, pre-treatment planning and assessment of patient outcomes. It is important for the radiologist to be familiar with imaging algorithms, best practices for surgery and/or radiotherapy and imaging findings in the post-treatment period that may indicate disease recurrence. In this review, we present a multidisciplinary discussion of spine metastases, with specific focus on pre-treatment imaging, planning, current treatment approaches, and post-treatment assessment.

Pre Treatment

Bacterial meningitis is an important cause of death and disability in sub-Saharan Africa and, with pre-treatment in peripheral health centres, the poorest populations could avoid early death, especially if they live far from hospital. During the 2001 meningitis epidemic in south Chad, Moyen Chari sanitary district peripheral health centres were equipped with oily chloramphenicol (CAP) to administer before hospital referral in suspected cases of meningitis. Eighty-six patients treated with CAP in whom the diagnosis was definitively confirmed subsequently in hospital were compared with patients receiving CAP at hospital admission during the same period. A statistically significant reduction in lethality rate, need of second line treatment or adjunctive antibiotics, and mean hospital stay were confirmed in pre-treated patients.
