Compliance With Guidelines on Seasonal Malaria Chemoprevention in Kwara State, Northcentral Nigeria.

BACKGROUND: Seasonal malaria chemoprevention (SMC) is an effective strategy for reducing malaria morbidity and mortality in children aged 3-59 months in areas with seasonal malaria transmission. Sulphadoxine-pyrimethamine plus amodiaquine is given to an eligible child at monthly intervals during the peak malaria transmission season. The aim of this study was to determine the level of compliance with SMC guidelines by community drug distributors during SMC implementation in Kwara State. METHOD: Caregivers of eligible children from six Local Government Areas were interviewed using a structured questionnaire on the KoboCollect app downloaded on hand-held android devices. The questionnaire was composed of questions on caregiver's demographics, SMC drug administration, and adherence to SMC protocol. RESULTS: A total of 1,314 caregivers were interviewed, most of them were female 1076 (81.9%), married 1200 (91.3%) and literate 795 (60.5%). The mean SMC coverage for the 4 cycles was 1183(88.5%). SMC information was received by 1166 (88.7%) of caregivers. Most of the caregivers 1166 (88.7%) heard about SMC. Overall, SPAQ administration was directly observed in most cases 1169 (91.5%), second dose was given 1226 (96.0%) and drugs were fully ingested 1140(89.3%). Poor compliance was observed in home visits by lead mothers 988 (77.4%). The report of adverse drug reactions was low 132 (10.3% [95% CI: 8.8-12.3%]), the commonest being severe vomiting 50 (37.9%). There were significant (P<0.05) variations in SMC implementation across the 6 LGAs in virtually all the performance indicators. SPAQ administration to over-age children was low 128 (10.0%). CONCLUSION: Overall, the compliance with SMC implementation guidelines in Kwara state was good though significant differences in performance were observed across the six LGAs. Home visits by lead mothers were generally poor. The self-reported coverage of SMC by caregivers was commendable.

CONTEXTE: La chimioprévention saisonnière du paludisme (CSP) est une stratégie efficace pour réduire la morbidité et la mortalité liées au paludisme chez les enfants âgés de 3 à 59 mois dans les zones à transmission saisonnière du paludisme. La sulfadoxine-pyriméthamine associée à l'amodiaquine est administrée à un enfant éligible à intervalles mensuels pendant la saison de transmission maximale du paludisme. L'objectif de cette étude était de déterminer le niveau de conformité aux directives de la CSP par les distributeurs de médicaments communautaires lors de la mise en œuvre de la CSP dans l'État de Kwara. MÉTHODE: Les aidants des enfants éligibles de six zones de gouvernement local ont été interrogés à l'aide d'un questionnaire structuré sur l'application KoboCollect sur des appareils android portables. Le questionnaire comprenait des questions sur les caractéristiques démographiques des aidants, l'administration des médicaments de la CSP et l'adhésion au protocole de la CSP. RÉSULTATS: Au total, 1 314 aidants ont été interrogés, la plupart étaient des femmes 1 076 (81,9 %), mariées 1 200 (91,3 %) et alphabétisées 795 (60,5 %). La couverture moyenne de la CSP pour les 4 cycles était de 1 183 (88,5 %). La plupart des aidants 1 166 (88,7 %) avaient entendu parler de la CSP. Dans l'ensemble, la première administration de SPAQ a été observée directement dans la plupart des cas 1 169 (91,5 %), la deuxième dose a été administrée par 1 226 (96,0 %) aidants et les médicaments ont été entièrement ingérés sans cracher partiellement ou totalement par 1 140 (89,3 %) enfants. Une mauvaise conformité a été observée lors des visites à domicile par les mères responsables 988 (77,4 %). Le signalement des réactions indésirables aux médicaments était faible 132 (10,3 % [IC à 95 % : 8,8-12,3 %]), la plus courante étant les vomissements sévères 50 (37,9 %). Des variations significatives (P<0,05) dans la mise en œuvre de la CSP ont été observées dans les 6 LGAs pour pratiquement tous les indicateurs de performance. L'administration de SPAQ aux enfants plus âgés était faible 128 (10,0 %). CONCLUSION: Dans l'ensemble, la conformité aux directives de mise en œuvre de la CSP dans l'État de Kwara était bonne bien que des différences significatives dans les performances aient été observées dans les six LGAs. Les visites à domicile par les mères responsables étaient généralement mauvaises. La couverture autodéclarée de la CSP par les aidants était louable.

Highly pathogenic avian influenza (HPAI A H5N1) outbreak in Spain: its mitigation through the One Health approach - a short communication.

Highly pathogenic avian influenza (HPAI A H5N1) has occurred over the past few years, especially during the 1918-1919 Spanish Flu pandemic, which wiped out many people in the world. It caused acute illness in about 25-30% of the world's population, which led to the deaths of up to an estimated 40 million people. Of recent, public health authorities in Spain reported the detection of avian influenza A in two poultry workers on a single farm, following an outbreak in poultry confirmed on 20 September which was likely to be due to exposure to infected poultry or contaminated environments and poor interprofessional collaborations among the Spanish health workers. This is a public health challenge for the Spanish government and the world at large. Thus, we believed that through the One Health approach in Spain, there would be a stop to and prevention of further spread of the recent outbreak of avian influenza A in Spain, as well as other infectious diseases and future outbreaks in the country and the world at large.

Brucella melitensis Biovar 1 and Brucella abortus S19 Vaccine Strain Infections in Milkers Working at Cattle Farms in the Khartoum Area, Sudan.

BACKGROUND: Human brucellosis is a preventable zoonoses that may become persistent, causing, if left untreated, severe localized disease. Occupational exposure to infected animals or animal products and consumption of fresh contaminated dairy are main risk factors. METHODS: One hundred farmworkers employed at two cattle farms one in Khartoum North and one in Omdurman were screened for the presence of specific antibodies and seropositive workers were invited to donate a blood sample for blood culture. Molecular typing was used to characterize Brucella isolates. RESULTS: Ten percent of farmworkers tested seropositive and while Brucella melitensis biovar 1 was isolated from the blood of three individuals, an isolate identical to the B. abortus S19 vaccine strain was isolated from a fourth person. All four bacteremic individuals were employed as milkers and did not have obvious disease. CONCLUSIONS: The isolation of the highly infectious pathogen B. melitensis from seropositive workers is consistent with the notion that the pathogen may persist in the blood without causing overt disease. While vaccination with strain S19 is essential for the control of bovine brucellosis the vaccine strain may be transmitted to the human population and protective measures remain important to prevent exposure also in view of the presence of B. melitensis. To create awareness for this potentially severe disease more information on the prevalence of the pathogen in different risk groups and in livestock in the Sudan is needed.

Profiles of acute bacterial meningitis isolates in children in National Hospital, Abuja.

BACKGROUND: Acute bacterial meningitis (ABM) is an important cause of morbidity and mortality throughout the world. It is an acute medical emergency that requires urgent rational antibiotic therapy, especially in neonates and young infants. Determining the pattern and susceptibility of isolates of ABM among children for prompt treatment of this important cause of mortality and morbidity is very important. This study determined the types and the antimicrobial susceptibility pattern of ABM isolates among children at the National Hospital, Abuja. MATERIALS AND METHODS: This is a retrospective study carried out at the National Hospital Abuja (NHA), Nigeria. Laboratory data for a period of 3 years, January 2010-December 2013 were reviewed, and all bacterial isolates and their antibiotics sensitivity testing results for children aged 0-15 years, and other relevant information extracted and analyzed. Study center was the NHA. RESULTS: Twenty-eight bacterial pathogens were isolated from a total of 542 cerebrospinal specimens over the study period, giving a yield of 5.2%. The four most common pathogens isolated were Staphylococcus aureus (32.2%), Klebsiella pneumoniae (21.5%), Streptococcus pneumoniae (17.6%), and Escherichia coli (14.3%). Whereas, 28.6% of all the infections occurred in neonates alone, children 2 years and below had 85.7% of all the infections, with male preponderance. Isolates of S. aureus and S. pneumonia tested were both 100% susceptible to amoxicillin-clavulanic acid and Cefuroxime; S. pneumoniae was equally sensitive to Ceftriaxone. K. pneumoniae was 100% sensitive to Imipenem, but 83% to ceftriaxone. 75% of the isolated E. coli strains were sensitive to ceftriaxone, amoxicillin-clavulanic acid, and amikacin, 100% sensitive to imipenem. CONCLUSION: Meningitis in children as seen in the National hospital is almost equally caused by both Gram-positive and Gram-negative organisms, predominantly by S. aureus, S. pneumoniae, K. pneumoniae, and E. coli. Available drugs remain active against these organisms.

Study of patients with community-acquired abscesses.

BACKGROUND: Abscess incision and drainage (I&D) operations form the bulk of surgical procedures in the emergency department (ED). Nevertheless, epidemiologic, clinical, and bacteriology data are lacking for patients with abscesses presenting at Sudanese hospitals. Information also is unavailable on the magnitude of the problem of community-acquired methicillin-resistant Staphylococcus aureus (CA-MRSA) and its susceptibility to the most commonly used antibiotics. Our objectives were (1) to identify and document the epidemiologic and clinical variables of patients with superficial abscesses; (2) to isolate the causative organism(s) from the pus and determine their antibiotic sensitivity; (3) to determine the prevalence of CA-MRSA and its antibiotic susceptibility; and (4) to audit our practice of I&D of abscesses. METHODS: A prospective observational study, involving a convenience sample of patients who presented with community-acquired skin and soft tissue (superficial) abscesses to a single unit at Khartoum North Teaching Hospital (KNTH) ED, was done for the years 2009-2010. A pro-forma was designed to record the personal, epidemiologic, and clinical data of each patient. All I&D operations were performed as day cases. Swabs of pus drained from the abscess were sent to the laboratory for culture. Isolates underwent sensitivity testing against the most commonly used antibiotics. RESULTS: A total of 248 patients were included. The majority (84%) were younger than 40 years of age. There were twice as many male as female patients (69% vs. 31%, respectively). The majority of patients did not have a known predisposing factor, but 13% had a history of an abscess. A history of trauma was found in 27% of the patients, whereas diabetes mellitus was found in only 6%. The most common site of the abscess was the upper limb (46%) followed by the lower limb (20%). Most (85%) of the abscesses were drained under local anesthesia. Sensitivity tests were performed on 151 pus isolates. No growth was obtained in 28 (18.5%) of the specimens. Of the 123 specimens yielding growth, S. aureus was the most common organism (90%), followed by Klebsiella spp. (6.5%). The proportion of CA-MRSA was 24%. Many of these S. aureus isolates were resistant to other antibiotics also. CONCLUSION: This study documents some epidemiologic and bacteriological data on one of the most common surgical problems. We found a substantial proportion of the infecting organisms to be CA-MRSA. This reflects the abuse of antibiotics in the community and stresses the importance of health education. Standardized surgical and anesthetic guidelines should be followed for I&D of abscesses to avoid recurrence. Further studies are needed urgently.
