Summary
A rare deep neck abscess caused by multidrug-resistant Acinetobacter baumannii (A. baumannii) was successfully treated. This finding highlights the importance of considering A. baumannii in severe nosocomial infections.
Area of Science:
- Infectious Diseases
- Critical Care Medicine
- Microbiology
Background:
- Acinetobacter baumannii (A. baumannii) is a significant cause of nosocomial infections, particularly in intensive care units.
- A. baumannii infections are associated with high mortality rates and can manifest in various forms, including pneumonia and septicemia.
- Multidrug-resistant strains pose a substantial challenge in clinical management.
Observation:
- A case of an extremely rare deep neck abscess caused by multidrug-resistant A. baumannii is presented.
- The patient required surgical intervention (two neck explorations) and antibiotic therapy with tigecycline.
Findings:
- Repetitive sequence-based polymerase chain reaction (rep-PCR) typing identified the index case's A. baumannii strain.
- The analysis revealed four distinct strain profiles among hospital isolates during the study period.
- Profile A was the most prevalent (18 isolates), with the index case representing profile B.
Implications:
- This case underscores the potential for A. baumannii to cause rare but severe infections like deep neck abscesses.
- Successful treatment with tigecycline demonstrates a viable therapeutic option for such challenging infections.
- Understanding strain diversity through molecular typing is crucial for infection control and epidemiological surveillance in healthcare settings.

01:26Brain Abscess l: Introduction
A brain abscess is a focal, intracerebral infection characterized by a localized collection of pus within the brain parenchyma, resulting from microbial invasion and the body’s inflammatory response. It progresses through stages: early and late cerebritis, followed by early and late capsule formation, reflecting tissue destruction, immune response, and eventual encapsulation.Etiology and PathogenesisCausative organisms vary with source and host factors, often involving polymicrobial infections,...
01:28Acute Pyelonephritis II: Diagnostic Studies and Management
Introduction:For diagnosing acute pyelonephritis, a comprehensive patient history is collected to identify symptoms such as dysuria, frequent or urgent urination, flank pain, or costovertebral angle (CVA) tenderness that may suggest a kidney infection.Physical ExaminationDuring the physical examination, CVA tenderness is assessed. This involves gentle percussion over the costovertebral angle, where tenderness often indicates a kidney infection.Diagnostic TestsUrinalysis: Used to identify white...
01:27Acne Infection
Acne is a multifactorial skin condition primarily affecting adolescents and young adults, with a global prevalence estimated to exceed 75% in this demographic. The condition is characterized by the formation of comedones (blackheads and whiteheads), papules, pustules, nodules, and, in severe cases, cysts, particularly in areas rich in sebaceous glands such as the face, neck, chest, and back. The pathogenesis involves increased sebum production, follicular hyperkeratinization, colonization by...
01:27Acute Pyelonephritis I: Introduction
Pyelonephritis is a bacterial infection that primarily affects the renal parenchyma and collecting system, including the renal pelvis, tubules, and interstitial tissue of one or both kidneys. It can be classified as either acute—a sudden, severe infection—or chronic, which refers to long-term or recurrent kidney infections.The primary cause of acute pyelonephritis (APN) is bacterial infection, with Escherichia coli accounting for approximately 70-80% of cases. Other bacteria, such as Proteus,...

Vigilant monitoring for aneurysm rupture is essential for patients undergoing aortic surgery.Preoperative Nursing ManagementContinuously monitor the patient for manifestations of aneurysm rupture, such as pallor, weakness, tachycardia, hypotension, abdominal, back, groin, or periumbilical pain, changes in consciousness, and a pulsating abdominal mass. Regularly assess the patient's peripheral pulses.Instruct the patient to consume a clear liquid diet the day before surgery and administer...
01:22Bacterial Meningitis I: Introduction
Bacterial meningitis is a severe, life-threatening inflammation of the meninges, particularly the pia mater and arachnoid mater, affecting the subarachnoid space, ventricles, and cerebrospinal fluid (CSF). If untreated, it can lead to significant neurological complications or death.Causative AgentsCommon pathogens vary with age and immune status. In adults, major organisms include Streptococcus pneumoniae, Neisseria meningitidis, and Haemophilus influenzae. Streptococcus agalactiae (group B...
