Insights

Urinary tract infections (UTIs) in children caused by Streptococcus pneumoniae are rare but often linked to underlying renal or urological issues. Prompt urinary tract imaging is recommended for these atypical pediatric UTIs.

Area of Science:

  • Pediatric Infectious Diseases
  • Urology
  • Microbiology

Background:

  • Urinary tract infections (UTIs) are common in children, typically caused by enterobacteria.
  • Streptococcus pneumoniae is an infrequent cause of pediatric UTIs.

Purpose of the Study:

  • To present a case of pediatric UTI caused by Streptococcus pneumoniae.
  • To review literature and discuss the necessity of urinary tract imaging in such cases.

Main Methods:

  • A case report of a 2-year-old girl with recurrent febrile UTI due to Streptococcus pneumoniae.
  • Literature review of 16 additional cases of pediatric UTIs caused by Streptococcus pneumoniae.
  • Diagnostic imaging including voiding cystourethrogram and renal scintigraphy.

Main Results:

  • The patient had a history of megaureter, left hydronephrosis, and grade V vesicoureteral reflux.
  • Renal scintigraphy indicated severe left kidney functional compromise.
  • Of the 17 total cases reviewed, 70% (12 cases) had associated renal-urological abnormalities.

Conclusions:

  • Pediatric UTIs caused by Streptococcus pneumoniae are often associated with significant renal-urological alterations.
  • Urinary tract imaging studies are crucial for identifying these underlying conditions in children with atypical UTIs.

Disorders of the Urinary System

The urinary system is responsible for eliminating waste and excess fluids from the body. However, disorders of the urinary system can arise due to various reasons like infections, stress, age, congenital abnormalities, and lifestyle.
Urinary tract infections (UTIs) are one of the most common urinary system disorders. They are caused by bacteria that enter the urethra and can spread to the bladder resulting in cystitis. Pyelonephritis is the result of a UTI that has ascended to the level of the...

Pneumonia I: Introduction01:30

Pneumonia I: Introduction

Pneumonia is an acute respiratory infection that targets the lungs, specifically the alveoli. These tiny air sacs, essential for oxygen exchange, become engorged with pus and fluid, severely hindering breathing, decreasing oxygen absorption, and causing significant pain and discomfort during respiration.
Risk Factors
Various factors influence the likelihood of developing pneumonia. Age plays a crucial role, with infants, children under two, and individuals over 65 at increased risk due to their...

Teratogenicity01:07

Teratogenicity

The ability of a drug to produce structural deformations and functional abnormalities in the developing embryo or the fetus is called teratogenicity, and the drug producing this effect is known as a teratogen. Teratogenic effects include stillbirth, miscarriage, intrauterine growth restriction, and neurocognitive delay. A teratogen may affect the embryo at different stages of development, which is important in determining the type and extent of the damage. During blastocyst formation, the early...

Physiology of Urine Formation01:24

Physiology of Urine Formation

Urine formation is an essential function of the human body. It plays a critical role in maintaining homeostasis by regulating the volume and composition of body fluids. The kidneys, the primary organs involved in this process, filter blood to remove waste products and excess substances, ultimately producing urine.
Glomerular Filtration
The first stage in urine formation is glomerular filtration. Each kidney contains approximately 1 million nephrons, the functional units of filtration, with a...

Sexually Transmitted Infections

Sexually transmitted infections (STIs) are diseases transmitted primarily through unsafe sexual interactions. Bacteria, viruses, or parasites cause them and can result in severe health complications if untreated.ChlamydiaThe bacterium Chlamydia trachomatis is responsible for the disease Chlamydia, the most common STI in the United States. This peculiar pathogen requires human cells to reproduce, residing intracellularly. The initial infection often goes unnoticed because it typically does not...
