Summary
Bartonella henselae can cause neuroretinitis, an eye condition, even without typical cat scratch disease symptoms. Prompt antibiotic treatment is crucial for recovery and preventing serious complications.
Area of Science:
- Ophthalmology
- Infectious Diseases
- Microbiology
Background:
- Cat scratch disease (CSD) is typically caused by Bartonella henselae, presenting with lymphadenopathy and fever.
- Neuroretinitis is an ocular condition involving inflammation of the optic nerve and retina.
- This study investigates atypical presentations of Bartonella neuroretinitis.
Observation:
- Three patients with neuroretinitis were evaluated for Bartonella henselae infection.
- None of the patients reported a history of cat contact or exhibited classic CSD symptoms.
- Ocular examinations revealed optic disc edema and macular exudates.
Findings:
- Serologic testing using indirect immunofluorescence assay (IFA) confirmed Bartonella henselae infection in all three patients.
- Two patients treated with antibiotics showed gradual resolution of ocular signs.
- The untreated patient experienced serious complications, highlighting the importance of timely intervention.
Implications:
- Bartonella henselae should be considered in the differential diagnosis of neuroretinitis, even in the absence of systemic CSD signs.
- Early antibiotic treatment is vital for favorable visual outcomes and preventing severe complications.
- This expands the known clinical spectrum of Bartonella henselae infections.

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...

01:15Drug 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...

In the United States, obesity is a prominent concern. It is linked to heightened mortality rates due to increased occurrences of conditions such as hypertension, atherosclerosis, coronary artery disease, and diabetes compared to nonobese individuals. A patient is classified as obese if their actual body weight surpasses the ideal or desirable body weight by 20%, based on Metropolitan Life Insurance Company data. Ideal body weights consider average weights and heights for males and females...

01:27Pharmacodynamics in Geriatric Patients: Effects of Age
239
Age-related pharmacokinetic changes are extensively documented, but understanding age-related pharmacodynamic alterations is relatively limited. This knowledge gap can be partly attributed to the complexity of developing appropriate measures of drug responses compared to bioanalytical methods for determining drug concentrations.Most information regarding age-related differences in human pharmacodynamics originates from cross-sectional studies. However, these studies assume that observed mean...

01:26Pharmacokinetics in Pediatric Patients: Drug Excretion
266
In pediatric medicine, understanding the renal function and drug elimination nuances is crucial for administering safe and effective treatments. Newborns, in particular, display markedly slower renal functions than adults, profoundly affecting how drugs are cleared from their bodies. This slower drug clearance requires clinicians to extend the dosing intervals for many medications to prevent drug accumulation and toxicity while ensuring therapeutic efficacy.One key area where these adjustments...

Drug distribution in the pediatric population exhibits unique challenges and considerations due to the physiological differences between children, particularly neonates and infants, and adults. A crucial aspect of pediatric pharmacology is understanding how these differences impact the pharmacokinetics of various drugs, necessitating age-specific dosing strategies to ensure efficacy and safety.Neonates and infants have a higher total body water content, ~75%–90% of their body weight,...
