Insights
A boy with fever and hip pain was diagnosed with Salmonella enterica infection of the hip joint. Prompt surgical drainage and antibiotics led to a favorable outcome, highlighting the importance of early intervention for invasive salmonellosis in children.
Area of Science:
- Pediatric infectious diseases
- Orthopedic surgery
- Microbiology
Background:
- Invasive Salmonella spp infections, though less common than non-invasive forms, are associated with higher hospitalization, morbidity, and mortality rates.
- Children, the elderly, and immunocompromised individuals are at increased risk for severe outcomes from Salmonella infections.
Observation:
- An 11-year-old boy presented with acute symptoms of fever and right hip pain, accompanied by limited mobility.
- Computed tomography (CT) scan of the hip revealed significant joint effusion and swelling.
Findings:
- Surgical intervention was necessary to drain purulent material from the right coxo-femoral joint.
- Cultures from the drained fluid identified Salmonella enterica as the causative pathogen.
- The patient received a four-week course of a third-generation cephalosporin, resulting in a positive clinical response.
Implications:
- This case underscores the potential for Salmonella enterica to cause severe invasive joint infections in pediatric patients.
- Early diagnosis, surgical management, and appropriate antibiotic therapy are crucial for favorable outcomes in invasive salmonellosis.
- Recognizing high-risk populations is essential for timely and effective management of Salmonella infections.
Abstract:
An eleven-year-old boy presented with fever and hip pain, with limited mobility of the right side of the hip. Computed tomography scan revealed an increased volume of the right coxo-femoral joint, requiring surgical drainage of purulent secretion, from which Salmonella enterica was isolated. After four weeks of treatment with third-generation cephalosporin, he was discharged with a favorable evolution. Invasive disease caused by Salmonella spp represents a small proportion of salmonellosis cases, although it is responsible for greater rates of hospitalization, morbidity and mortality. Children under 5 years, elders over 60 years and immunodeficient patients have greater risk for invasive salmonellosis.

Introduction to Documentation and Reporting
Nursing documentation records essential information and details regarding a patient's care and treatment in written or electronic form. It is a critical aspect of nursing practice that involves documenting assessments, interventions, outcomes, and other relevant details about a patient's health status.
Documentation maps the patient's health journey by creating a comprehensive...
