Purpose:
To report a series of patients with acute-onset bacterial endophthalmitis caused by culture proven Staphylococcus lugdunensis, and to characterize clinical outcomes and microbiologic susceptibilities of this organism.
Observations:
The study included six eyes of 6 patients. The etiologies included cataract surgery (3), open globe injury (2), and intravitreal injection (1). Isolates of S. lugdunensis demonstrated sensitivity to vancomycin in all cases reported. Three of 6 isolates of S. lugdunensis demonstrated resistance to oxacillin and 1 isolate demonstrated resistance to ciprofloxacin. Best-corrected visual acuity was ≥20/400 in 6/6 (100%) of eyes and ≥20/40 in 3/6 (50%) of cases.
Conclusion And Importance:
Acute-onset endophthalmitis caused by S. lugdunensis is associated with variable visual outcomes. Vancomycin provides consistent coverage of acute-onset endophthalmitis cause by S. lugdunensis.

Acute Pharyngitis
Acute pharyngitis is the inflammation of the back of the throat (pharynx), commonly resulting in a sore throat. It is a frequently encountered condition that prompts individuals to seek medical advice.
Classification
Acute pharyngitis can be categorized based on its underlying cause:
Acute Pancreatitis I: Introduction
Acute pancreatitis is characterized by rapid inflammation of the pancreas, often caused by factors like gallstone blockage or excessive alcohol consumption. Chronic pancreatitis, on the other hand, is a slow, progressive inflammation that may result from long-term alcohol abuse, obstructions in the pancreatic duct, or genetic factors.
The causes of acute pancreatitis include:
Acute Pyelonephritis I: Introduction
Acute Respiratory Failure-I
Definition: It is defined by specific criteria based on blood gas measurements. Hypoxemia happens when the partial pressure of oxygen (PaO2) falls below 60 mmHg. At the same time,...
Acute Respiratory Failure-II
The underlying physiological abnormalities that contribute to hypoxemic respiratory failure include:
Acute Respiratory Failure-V
Ensure that patients are monitored continuously for their response to therapy, including changes in...
