Prevalence and Outpatient Clinical Diagnostic Approaches for Common Acute Respiratory Tract Infections in Children Under Five Years of Age: A Cross-Sectional Study.

Background: Acute respiratory tract infections are among the leading causes of child morbidity and mortality worldwide. Although the diagnosis of acute respiratory tract infections requires simple outpatient medical techniques and care, it is still misdiagnosed among primary care physicians, leading to delayed treatment and increased mortality. This study described the prevalence of common acute respiratory tract infections and simple techniques that effectively detect and diagnose children presenting with acute respiratory symptoms to primary healthcare physicians in remote settings. Patients and Methods: This descriptive cross-sectional study was conducted at the pediatric outpatient clinic of a tertiary hospital in western Uganda in April, May and June 2019. A total of 896 children aged 2-59 months attending the clinic were recruited consecutively into the study and examined for the presence of acute respiratory infection. Participants' sociodemographic and clinical data were collected through history taking and clinical examination using a validated Uganda Ministry of Health Uganda outpatient clinical checklist (FORM 5). The outcome variable was the presence of an acute upper or lower respiratory condition. Data was analyzed using STATA version 13.0 (StataCorp, College Station, USA) and summarized using descriptive statistics. Results: The overall period prevalence of acute respiratory tract infections among children aged 2 to 59 months was 36.9% (36,942 per 100,000 population). Upper respiratory tract infections with a prevalence of 24.8% were more common than lower respiratory tract infections. The most frequent upper respiratory tract infection in this setting was common cold (52%), followed by tonsillopharyngitis (10.7%), while pneumonia (26%) was the most frequent lower respiratory tract infection. Conclusion: Acute respiratory tract infections contribute to the high burden of disease in pediatric outpatient clinics. Simple, affordable, and approved diagnostic clinical techniques that involve physical examination of the upper and lower respiratory systems can precisely diagnose acute respiratory tract infections in resource-limited settings where there is no access to sophisticated diagnostic equipment.

Sickle Cell Disease in Children and Adolescents: A Review of the Historical, Clinical, and Public Health Perspective of Sub-Saharan Africa and Beyond.

Sickle cell disease (SCD) is an umbrella term for a group of life-long debilitating autosomal recessive disorders that are caused by a single-point mutation (Glu→Val) that results in polymerization of hemoglobin (Hb) and reversible sickle-shape deformation of erythrocytes. This leads to increased hemolysis of erythrocytes and microvascular occlusion, ischemia-reperfusion injury, and tissue infarction, ultimately causing multisystem end-organ complications. Sickle cell anemia (HbSS) is the most common and most severe genotype of SCD, followed by HbSC, HbSß 0thalassemia, HbSß+thalassemia, and rare and benign genotypes. Clinical manifestations of SCD occur early in life, are variable, and are modified by several genetic and environmental factors. Nearly 500 children with SCD continue to die prematurely every day, due to delayed diagnosis and/or lack of access to comprehensive care in sub-Saharan Africa (SSA), a trend that needs to be urgently reversed. Despite proven efficacy in developed countries, newborn screening programs are not universal in SSA. This calls for a consolidated effort to make this possible, through the use of rapid, accurate, and cheap point-of-care test kits which require minimal training. For almost two decades, hydroxyurea (hydroxycarbamide), a century-old drug, was the only disease-modifying therapy approved by the U.S. Food and Drug Administration. Recently, the list expanded to L-glutamine, crizanlizumab, and voxelotor, with several promising novel therapies in the pipeline. Despite its several limitations, hematopoietic stem cell transplant (HSCT) remains the only curative intervention for SCD. Meanwhile, recent advances in gene therapy trials offer a glimpse of hope for the near future, although its use maybe limited to developed countries for several decades.

Germinal Matrix-Intraventricular Hemorrhage: A Tale of Preterm Infants.

Germinal matrix-intraventricular hemorrhage (GM-IVH) is a common intracranial complication in preterm infants, especially those born before 32 weeks of gestation and very-low-birth-weight infants. Hemorrhage originates in the fragile capillary network of the subependymal germinal matrix of the developing brain and may disrupt the ependymal lining and progress into the lateral cerebral ventricle. GM-IVH is associated with increased mortality and abnormal neurodevelopmental outcomes such as posthemorrhagic hydrocephalus, cerebral palsy, epilepsy, severe cognitive impairment, and visual and hearing impairment. Most affected neonates are asymptomatic, and thus, diagnosis is usually made using real-time transfontanellar ultrasound. The present review provides a synopsis of the pathogenesis, grading, incidence, risk factors, and diagnosis of GM-IVH in preterm neonates. We explore brief literature related to outcomes, management interventions, and pharmacological and nonpharmacological prevention strategies for GM-IVH and posthemorrhagic hydrocephalus.

Intestinal Obstruction in a Child with Massive Ascariasis.

Soil-transmitted helminths are so prevalent in the tropics and low developing countries. Pediatric clinical presentation of ascariasis, the most common helminth, as the intestinal obstruction is not only rare but also less described. We present a case of a 4-year-old girl with massive ascariasis. She presented with a 3-day history of acute abdominal pain associated with vomiting and an episode of passing long white roundworms, about 5 cm in length, through the nose. The child had mild constipation and passed pellets of hard stool once in the last 72 hours. She was in fair general condition at the examination but had significant findings on abdominal examination. On palpation, there was a soft mass localized in the left paraumbilical area and no tenderness, with normal bowel sounds on auscultation. Exploratory laparotomy was sanctioned where roundworms (Ascaris lumbricoides), saucepan full, were delivered through a 2.5 cm enterotomy incision. Postoperative management was carried out, and the child discharged on the 7th day of treatment including a 3-day course of albendazole 400 mg daily.

Prevalence and associated factors of pneumonia among under-fives with acute respiratory symptoms: a cross sectional study at a Teaching Hospital in Bushenyi District, Western Uganda.

Objectives: This study assessed the prevalence and associated factors of pneumonia among children under-five years presenting with acute respiratory symptoms. Methodology: This was a cross sectional study at the Pediatric Department of Kampala International University - Teaching Hospital, from the month of April to August 2019. The study included 336 children aged 2 to 59 months presenting with acute respiratory symptoms to the pediatric clinic. Pneumonia diagnosis was made according to the World Health Organization definition, modified by a chest radiograph. Structured questionnaires were used to collect data on socio-demographic, environmental and nutrition factors and multivariate logistic regression analysis using STATA version 13.0 was done to assess for the factors independently associated with pneumonia. Results: Of the 336 children with acute respiratory symptoms, eighty-six, 86 (25.6%) had pneumonia. Factors significantly associated with pneumonia included: age below 6 months (OR=3.2, 95%CI=1.17-8.51, p=0.023), rural residence (OR=5.7, 95%CI=2.97-11.05, p <0.001), not up-to-date for age immunization status (OR=2.9, 95%CI=1.05-7.98, p=0.039), severe acute malnutrition (OR=10.8, 95%CI=2.01-58.41, p=0.006), lack of exclusive breastfeeding during the first six months (OR=2.9, 95%CI=1.53-5.53, p=0.001) and exposure to cigarette smoke (OR=3.0, 95%CI=1.35-6.80, p=0.007). Conclusion: The prevalence of pneumonia in children under-five years was high. Most of the factors associated with pneumonia are modifiable; addressing these factors could reduce this prevalence.

Bacteriology and Antibiotic Susceptibility Patterns among Neonates Diagnosed of Omphalitis at a Tertiary Special Care Baby Unit in Western Uganda.

BACKGROUND: Newborn infections remain a major cause of morbidity and mortality among neonates in low-income countries. Clinical diagnosis for omphalitis in such settings is possible but this does not depict the microbiological characteristics of the involved organisms, and clinicians have often prescribed empirical antibiotics in neonates with omphalitis, despite an increasing burden of antibiotic resistance. METHODS: A hospital-based cross-sectional study was conducted to evaluate the bacteriology and antibiotic susceptibility patterns among neonates diagnosed with omphalitis at the special care baby unit (SCBU) of Kampala International University-Teaching Hospital (KIU-TH), western Uganda from March to June 2019. Sixty-five (65) neonates with a clinical diagnosis of omphalitis were consecutively recruited in the study. Cord swabs were taken under sterile (aseptic) precautions from all neonates, and antibiotic susceptibility tests performed using the Kirby Bauer disk diffusion technique with commercially available antibiotics disks of ampicillin, cloxacillin, gentamicin, amikacin, cefotaxime, ceftriaxone, vancomycin, and imipenem on Mueller Hinton agar plates. The data was analyzed using STATA version 13.0, frequencies and proportions used to describe the variables. RESULTS: Fifty-five, 55 (84.6%), neonates with suspected omphalitis had positive cord swab culture. Staphylococcal aureus (58.2%) was the commonest cause of omphalitis followed by Neisseria spp (16.4%), E. coli 6 (10.9%), Proteus spp (5.5%), Klebsiella spp (3.6%), Citrobacter spp (3.6%), and Haemophilus spp (1.8%) in decreasing frequency. Isolates were resistant to ampicillin (87.7%), gentamicin (54.4%), and cloxacillin (34.4%), the drugs recommended for use in neonates with suspected omphalitis. CONCLUSIONS: Staphylococcal aureus is still the predominant cause of omphalitis among neonates. There was high resistance to the commonly used antibiotics in the treatment of omphalitis among newborns. This study reemphasizes that clinicians should do cord swabbing for both culture and susceptibility tests among newborns with suspected omphalitis before initiation of antibiotics.

Preterm Neonatal Mortality and Its Determinants at a Tertiary Hospital in Western Uganda: A Prospective Cohort Study.

BACKGROUND: Prematurity contributes greatly to the neonatal mortality burden in sub-Saharan Africa. This study evaluated the proportion of preterm neonatal death, medical conditions at admission, and determinants of mortality of preterm neonates in the neonatal intensive care unit (NICU) of a tertiary hospital in Western Uganda. MATERIALS AND METHODS: A prospective cohort study of 351 consecutively enrolled preterm neonates was conducted from March to June 2019. Interviewer-administered questionnaires and physical assessment of neonates were used to obtain socio-demographic and clinical data for mothers and their preterm neonates. Descriptive statistics for participants' characteristics were generated, while bivariate and multivariate logistic regression models were fitted so as to establish the determinants of mortality outcome. A p-value <0.05 was considered statistically significant. RESULTS: In-hospital neonatal mortality of 31.6% (95% CI: 26.9-36.7) was noted, with 65.8% of deaths occurring within 72 hours from admission. The most common medical conditions at admission were: hypothermia (67.2%), respiratory distress syndrome (43.0%), small for gestational age (15.7%), and perinatal asphyxia (14.5%). Under multivariate regression modelling, maternal age ≥35 years (AOR: 4.5; 95% CI: 1.35-15.31), no antenatal care (AOR: 4.7; 95% CI: 1.05-21.21), >4 ANC visits (AOR: 5.3; 95% CI: 1.88-15.21), neonatal resuscitation (AOR: 3.4; 95% CI: 1.66-6.82), outborn status (AOR: 2.3; 95% CI: 1.20-4.50), singleton pregnancy (AOR: 3.7; 95% CI: 1.74-7.89), <28 weeks' gestation (AOR: 12.0; 95% CI: 2.24-64.27), and male sex (AOR: 2.0; 95% CI: 1.04-3.74), respiratory distress syndrome (AOR: 2.6; 95% CI: 1.22-5.70), apnea (AOR: 6.2; 95.5% CI: 1.09-35.38), hypothermia (AOR: 2.3; 95% CI: 1.09-4.92), and small for gestational age (AOR: 4.7; 95% CI: 2.06-10.74) were significantly associated with mortality. CONCLUSION AND RECOMMENDATIONS: In-hospital mortality of preterm neonates was high. We identified various maternal and neonatal risk factors, indicating a need for stakeholders to enhance efforts towards prevention of preterm-associated complications and optimize facility-based continuum of care.

Challenges Faced by Village Health Teams (VHTs) in Amuru, Gulu and Pader Districts in Northern Uganda.

Primary health care provision through innovative community level interventions such as the Village Health Team (VHT) concept in Uganda can be a rational way of achieving universal access to healthcare. This cross-sectional study interviewed 150 VHT members and 16 key informants in three districts in Northern Uganda to establish the roles of VHTs, the service gaps encountered and the measures in place to address these gaps. Quantitative data were analyzed using SPSS 16.0. Direct content analysis of themes of transcribed qualitative data was conducted manually for common codes. The majority of the respondents 64.29% (n = 72) reported to have been VHT volunteers for more than 5 years. Among the roles were community mobilization reported by 99.1% (n = 111) and home visiting of individuals reported by 97.3% (n = 109). Lack of transport, motivation, adequate skills and community appreciation with nearly no measures in place to counteract the challenges was reported by almost all respondents. Although the VHT concept can be a significant means of achieving universal access to primary health care, extensive community involvement and motivation of the volunteers are highly needed for a maximum benefit.
