Public health radiography: A scoping review of benefits, and growth opportunities for radiographers.

Introduction: There is growing adoption of radiographic techniques in public health to improve outcomes of chronic and communicable diseases. This review examines the applications, benefits, and implications of radiography in public health. It also examines the challenges and potential advanced practice roles for radiographers in public health radiography (PHR).

Bacteraemia in sickle cell anaemia is associated with low haemoglobin: a report of 890 admissions to a tertiary hospital in Tanzania.

Bacteraemia is a leading cause of morbidity in sickle cell anaemia (SCA), but information from studies in Africa is limited. We evaluated 890 admissions from 648 SCA patients at a tertiary hospital in Tanzania. Bacteraemia was present in 43 admissions (4·8%); isolates included Staphylococcus aureus (12/43; 28%), non-Typhi Salmonella (9/43; 21%), Streptococcus pneumoniae (3/43; 7%) and Salmonella Typhi (2/43; 5%).

Mortality in sickle cell anemia in Africa: a prospective cohort study in Tanzania.

Background: The World Health Organization has declared Sickle Cell Anemia (SCA) a public health priority. There are 300,000 births/year, over 75% in Africa, with estimates suggesting that 6 million Africans will be living with SCA if average survival reaches half the African norm. Countries such as United States of America and United Kingdom have reduced SCA mortality from 3 to 0.

Age specific aetiological agents of diarrhoea in hospitalized children aged less than five years in Dar es Salaam, Tanzania.

Background: This study aimed to determine the age-specific aetiologic agents of diarrhoea in children aged less than five years. The study also assessed the efficacy of the empiric treatment of childhood diarrhoea using Integrated Management of Childhood Illness (IMCI) guidelines.

Methods: This study included 280 children aged less than 5 years, admitted with diarrhoea to any of the four major hospitals in Dar es Salaam.

Malaria in patients with sickle cell anemia: burden, risk factors, and outcome at the outpatient clinic and during hospitalization.

Approximately 280,000 children are born with sickle cell anemia (SCA) in Africa annually, yet few survive beyond childhood. Falciparum malaria is considered a significant cause of this mortality. We conducted a 5-year prospective surveillance study for malaria parasitemia, clinical malaria, and severe malarial anemia (SMA) in Dar-es-Salaam, Tanzania, between 2004 and 2009.

Prevalence of enteropathogenic viruses and molecular characterization of group A rotavirus among children with diarrhea in Dar es Salaam Tanzania.

Background: Different groups of viruses have been shown to be responsible for acute diarrhea among children during their first few years of life. Epidemiological knowledge of viral agents is critical for the development of effective preventive measures, including vaccines.

Methods: In this study we determined the prevalence of the four major enteropathogenic viruses - rotavirus, norovirus, adenovirus and astrovirus - was determined in 270 stool samples collected from children aged 0 - 60 months who were admitted with diarrhea in four hospitals in Dar es Salaam, Tanzania, using commercially available ELISA kits.

Analysis of the indications for routine lumbar puncture and results of cerebrospinal fluid examination in children admitted to the paediatric wards of two hospitals in East Africa.

Lumbar puncture (LP) is an important diagnostic tool for investigating neurological conditions/diseases. This study was carried out to compare the indications for lumbar puncture and findings of cerebrospinal fluid examination in children admitted to Muhimbili National Hospital (MNH) in Dar-es-salaam, Tanzania and Kilifi District Hospital (KDH) in Kenya. Records of all children admitted to the paediatric wards of the two hospitals from 1st November 2004 to 30th April 2005 with suspected central nervous system infections and had LPs performed were analysed.

Post-transfusion hepatitis C seroprevalence in Tanzanian children.

In Tanzania, children with malaria-associated anaemia are frequently given blood transfusions, and donor blood is not screened for hepatitis C virus (HCV) infection. To determine the seroprevalence of HCV infection in Tanzanian children previously transfused with blood, 184 children (92 transfused, 92 not transfused) aged between 15 and 59 months matched for age and sex were screened for HCV antibodies by the particle agglutination test using Serodia anti-HCV (Fujirebio Inc., Japan).

Prevalence of HIV type 1 infection, associated clinical features and mortality among hospitalized children in Dar es Salaam, Tanzania.

The aim of this study was to determine the prevalence of HIV-1 infection, the clinical spectrum of HIV-1-associated conditions and HIV-1-associated mortality among children hospitalized in the medical paediatric wards at Muhimbili Medical Centre (MMC), Dar es Salaam, Tanzania. All children admitted to the medical paediatric wards of MMC between August 1995 and January 1996 were eligible for the study. Testing for HIV antibodies was done using 2 consecutive enzyme linked immunosorbent assays (ELISAs).

Acute phase proteins as markers of systemic illness in acute diarrhoea.

Fifty-seven Tanzanian children, 6-25 months, hospitalized with acute diarrhoea were grouped according to whether there was clinical evidence of systemic infection (SI) (n = 35) or not (n = 22). Serum acute phase proteins were measured in samples taken within 48 h of admission. Means for C-reactive protein (CRP) and serum amyloid A (SAA) were significantly higher in children with SI compared to those without (geometric means (95% CI); CRP, mg/l: 22.

Dietary management of acute diarrhoea in children: effect of fermented and amylase-digested weaning foods on intestinal permeability.

Background: There is a strong relationship between diarrhoea, malnutrition, and intestinal integrity. To investigate the effect of different dietary-treatment on intestinal permeability during acute diarrhoea, 87 Tanzanian children aged 6-25 months were recruited to this study when admitted to hospital.

Methods: Children with acute diarrhoea were rehydrated and then randomly assigned to one of three dietary treatment groups: a conventional low-energy density porridge, a high-energy density amylase digested porridge (AMD), or a high-energy density amylase digested and then fermented porridge (FAD).

Improved energy intakes using amylase-digested weaning foods in Tanzanian children with acute diarrhea.

Amylase from germinating cereal grains enables the preparation of porridge with a higher energy density than conventional weaning foods. This food can be combined with fermentation, which inhibits pathogen growth. These food technologies are inexpensive, can be implemented at the household level, and are therefore particularly appropriate for use in developing countries.
