Brain Abscess l: Introduction

Brain 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,...

Endocarditis II: Clinical Features of Infective Endocarditis

Endocarditis can present various clinical features depending on the causative organism and the patient's underlying health conditions. Initially, the clinical features of infective endocarditis develop gradually, presenting with nonspecific symptoms that can be easily mistaken for other illnesses.General SymptomsEarly symptoms of infective endocarditis are fever, chills, weakness, malaise, fatigue, and weight loss. These symptoms reflect the systemic nature of the infection and the body's...

Acute 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...

Healthcare Associated Infections I: Iatrogenic, Exogenic and Endogenic

Healthcare Associated Infections I: Iatrogenic, Exogenic and Endogenic

Healthcare-associated infections (HAIs) occur in a healthcare facility while a person receives care for another ailment. This category also includes work-related infections among healthcare staff.
HAIs significantly increase the cost of health care. Extended stays in healthcare institutions, increased disability, increased costs of medications, including specialized antibiotics, and prolonged recovery times add to the patient's expenses and the healthcare institution and funding bodies. Common...

Acute Pyelonephritis I: Introduction

Acute 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,...

Bacterial Meningitis I: Introduction

Bacterial 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...

Summary

Necrotizing external otitis (NEO) is a severe ear infection. Early diagnosis and treatment of resistant otalgia and otorrhea in older, diabetic patients are crucial for preventing complications and mortality.

Area of Science:

Otolaryngology
Infectious Diseases

Background:

Necrotizing external otitis (NEO) is a life-threatening infection of the external auditory canal, mastoid, and skull base.
Increasing life expectancy in diabetic and immunocompromised populations necessitates a focus on conditions like NEO.

Purpose of the Study:

To review the clinical findings of patients diagnosed with NEO.
To identify common presentations and complications of NEO.

Main Methods:

A case review of 18 patients with NEO hospitalized between 2007-2011.
Analysis of patient demographics, clinical presentations, microbiological findings, and treatment outcomes.

Main Results:

Common symptoms included otalgia (100%), otorrhea (83.33%), ear canal edema/erythema (77.77%), and hearing loss (61.11%).

Endaural Endoscopic Atticoantrotomy (Retrograde Mastoidectomy) using a Constant Suction Bone-drilling Technique

Published on: May 23, 2021

Skull base osteomyelitis involving cranial nerves, particularly the facial nerve, occurred in 44.44% of patients.

Pseudomonas aeruginosa was identified in 38.88% of cultures, possibly due to prior antibiotic use. All patients responded to systemic antibiotics, with no mortality, though two experienced recurrence.

Conclusions:

Older diabetic patients with persistent otalgia and otorrhea resistant to routine treatment are at high risk for NEO.
Prompt diagnosis and appropriate treatment are essential to prevent severe complications and mortality from NEO.
