Drug Dosing: Geriatric Patients01:15

Drug Dosing: Geriatric Patients

278
Elderly individuals encompass a diverse population with varying degrees of age-related physiological changes. Defining the elderly presents challenges, as the geriatric population is often arbitrarily categorized as individuals older than 65. However, many individuals in this group lead active and healthy lives, with an increasing number surpassing 85 years and falling into the older elderly category. Physiological changes associated with aging impact performance capacity and homeostatic...

Infection01:20

Infection

12.8K
When a pathogen enters the body and reproduces, it can cause an infection, damage body cells, and cause illness symptoms that eventually lead to disease. Therefore, its prevention requires breaking the chain of infection.
The chain begins with pathogens: bacteria, viruses, fungi, prions, or parasites such as protozoa helminths. These can be present on the skin as transient or resident flora, or they can be acquired from the environment. Identifying and treating the type of infection and...

Stages of Infection

65.5K
Stages of infection describe what happens to a susceptible host once a pathogen invades the human body. The stages of infection are incubation, prodromal, illness, stage of decline, and convalescence. The incubation stage is the period from exposure to a pathogen until symptoms start. The infected person is unaware of impending illness as the pathogens grow and multiply within the body. The duration may vary depending on the type of infection. The incubation period of measles averages ten to...

Patient-centered Care01:13

Patient-centered Care

3.1K
Patient-centered care involves delivering care beyond inpatient hospitalization. Reflective practice can enhance a patient-centered approach. Reflective practice is a process of reasoning that considers all aspects of the present situation, including practicalities, learning from personal practice, and consideration of patient needs. Patients appreciate care decisions made while considering their input. Involving the patient in their care provides the patient with a sense of contribution rather...

Defense Mechanism Against Infection01:26

Defense Mechanism Against Infection

9.8K
Natural flora, body system defenses, and inflammation are natural barriers of the body against infectious agents regardless of previous exposure. Normal floras of the human body refer to the microbial population that colonizes the skin and mucous membranes.
In addition, many body organ systems have unique defenses against infection. The skin is an intact, multilayered surface preventing invasion by microorganisms unless impaired. Mucous membranes lining the mouth, nose, and eyelids are barriers...

Sexually Transmitted Infections01:26

Sexually Transmitted Infections

1.2K
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...

Summary

Rhodococcus equi, a bacterium causing pneumonia in horses, is increasingly found in immunocompromised humans. This case highlights an exceptional laryngeal infection in an HIV-positive patient, emphasizing poor prognosis due to weakened immunity.

Area of Science:

  • Microbiology
  • Infectious Diseases
  • Immunology

Background:

  • Rhodococcus equi is an aerobic, gram-positive bacillus.
  • Initially identified as a cause of bronchopneumonia in foals.
  • Increasingly recognized as an opportunistic pathogen in humans, particularly those who are immunocompromised.

Observation:

  • This report details an unusual case of laryngeal infection caused by Rhodococcus equi.
  • The patient presented with positive serology for human immunodeficiency virus (HIV).
  • This represents a rare manifestation of Rhodococcus equi infection.

Findings:

  • The study reviews clinical and epidemiological features of Rhodococcus equi infections.
  • Treatment typically involves rifampicin and/or erythromycin.
  • The prognosis is often poor, especially in immunocompromised individuals.

Implications:

  • Highlights the expanding spectrum of Rhodococcus equi infections in vulnerable populations.
  • Underscores the importance of considering Rhodococcus equi in the differential diagnosis of infections in HIV patients.
  • Suggests the need for continued surveillance and research into effective treatment strategies for Rhodococcus equi infections.
