Silent Invader: A Rare Case of Enterobacter aerogenes Empyema in a Hospice Patient With Complex Comorbidities.

 (recently renamed ) is an uncommon pathogen in pleural infections and empyema, typically associated with nosocomial urinary and gastrointestinal infections. This case report describes a 69-year-old male patient with chronic kidney disease, diabetes mellitus, and other comorbidities, who developed empyema despite broad-spectrum antibiotics. Pleural fluid cultures revealed , known for its ability to develop resistance through beta-lactamase production and efflux pumps, which complicates treatment.

A Case of Legionella Pneumonia with Rhabdomyolysis, with Extremely high Creatinine Kinase without Acute Kidney Injury in an Adult.

Unlabelled: is a bacterium that usually causes pulmonary disease but can rarely present with extrapulmonary manifestations, such as rhabdomyolysis. This is a case of Legionella infection with significant rhabdomyolysis but a lack of acute kidney injury. A 38-year-old male with a history of epilepsy presented to the emergency department after a seizure episode with confusion, fever, emesis and bruises.

Etiologies of Extreme Leukocytosis.

The objective of this study was to determine the etiologies and co-morbidities associated with extreme leukocytosis, which is characterized by a white blood cell (WBC) count ≥ 35 × 10 leukocytes/L.  Method: Retrospective chart review was conducted for all patients, aged 18 years and older, admitted to the internal medicine department between 2015 and 2021 with an elevated WBC count ≥ 35 × 10 leukocytes/L within the first 24 hours of admission.  Results: Eighty patients were identified to have WBC count ≥ 35 × 10 leukocytes/L.

Perinephric Abscess Extending to the Psoas Muscle and Causing a Nephro-Cutaneous Fistula.

We present a case of a 76-year-old male with dementia transferred from a nursing home with a fever and an abscess on his back. Workup revealed an extensive perinephric abscess, which extended to his psoas muscle, with an additional fistula to his back where the abscess was noted. The extent and tracking of the perinephric abscess were unusual as well as the organisms isolated, and species.

Adult-Onset Still's Disease in a 28-Year-Old Man From Ghana.

Adult-onset Still's disease is a rare, autoinflammatory disease characterized by spiking fevers, arthritis, salmon-colored skin rash, and leukocytosis. It has been compared to systemic juvenile idiopathic arthritis because of its similar features but is much rarer than its pediatric counterpart. It is usually treated with corticosteroids and disease-modifying anti-rheumatic drugs.

Severe Lower Extremity Cellulitis Caused by an Unusual Pathogen: Haemophilus Influenzae Type F.

We present a case of unusual cellulitis of the lower extremities caused by (HI). A 64-year-old female with human immunodeficiency virus (HIV) with a suppressed viral load on treatment, presented with severe, very painful cellulitis of her lower extremity. CT scan did not show any gas or collections; however, she was taken to the operating room for concern of necrotizing fasciitis but no evidence of deep tissue involvement was found.

Fever in trauma patients: evaluation of risk factors, including traumatic brain injury.

Background: The role of fever in trauma patients remains unclear. Fever occurs as a response to release of cytokines and prostaglandins by white blood cells. Many factors, including trauma, can trigger release of these factors.

Clostridium difficile at a community hospital in the Bronx, New York: incidence prevalence and risk factors from 2006 to 2008.

Background: The rate of Clostridium difficile has increased over the last decade. This study was undertaken to determine the incidence, prevalence, and risk factors for infection at a 460-bed community hospital in the Bronx, New York.

Method: Retrospective study reviewing all patients with a positive stool test for C difficile toxin A/B from 2006 to 2008.

Mycobacterium fortuitum and anaerobic breast abscess following nipple piercing: case presentation and review of the literature.

Purpose: Body piercing has become increasingly prevalent. We describe a case of breast infection with combined mycobacteria and anaerobe following nipple piercing, and review the literature.

Case: A 17-year-old female developed a breast abscess 4 months after nipple piercing.

Characterization of intersubtype recombinant HIV type 1 genomes using a nonradioactive heteroduplex tracking assay.

The HIV-1 epidemic is characterized by the dominance of distinct viral subtypes in different regions of the world, and intersubtype recombinants are common. Traditional subtyping methods analyze only a small fragment of the HIV-1 genome, so the true extent of diversity and recombination has been difficult to examine. We developed a heteroduplex tracking assay (HTA) to identify viral subtypes and rapidly detect recombinant HIV-1 genomes.
