Hyper-IgE syndrome: a case report.

Introduction and importance: Hyper-IgE syndrome (HIES), also known as Job syndrome, is a rare primary immunodeficiency disorder characterized by elevated serum IgE levels, recurrent infections, and various clinical features. Early diagnosis, prompt management of infections, and supportive care are essential in improving outcomes for individuals with HIES. Genetic testing, including STAT3 gene sequencing, plays a crucial role in confirming the diagnosis. Further research is needed to enhance our understanding of HIES and develop targeted therapies to improve the quality of life for affected individuals. Case presentation: This case report presents the clinical features and management of a 37-year-old male with HIES, diagnosed at the age of 2 due to recurrent cold abscesses caused by Staphylococcal infections. Clinical discussion: The patient exhibited typical symptoms of HIES, including recurrent eczema, frequent bacterial infections, mucocutaneous candidiasis, and various physical abnormalities. Diagnostic markers such as elevated IgE levels and eosinophilia supported the HIES diagnosis, which was further confirmed by the identification of a STAT3 gene mutation. Treatment primarily involved supportive measures and antibiotics for infections. The patient's blood test results and imaging findings revealed abnormalities such as low red blood cell count, elevated erythrocyte sedimentation rate, and pulmonary nodules. Conclusion: This case report highlights the importance of early diagnosis, prompt management of infections, and the need for ongoing research to improve our understanding and treatment of HIES.

Neurological and Psychiatric Manifestations of Long COVID-19 and Their [18F]FDG PET Findings: A Review.

For more than two years, lingering sequalae of COVID-19 have been extensively investigated. Approximately 10% of individuals infected by COVID-19 have been found to experience long-term symptoms termed "long COVID-19". The neurological and psychiatric manifestations of long COVID-19 are of particular concern. While pathogenesis remains unclear, emerging imaging studies have begun to better elucidate certain pathological manifestation. Of specific interest is imaging with [18F]FDG PET which directly reflects cellular glycolysis often linked to metabolic and inflammatory processes. Seeking to understand the molecular basis of neurological features of long COVID-19, this review encompasses the most recent [18F]FDG PET literature in this area.

Klebsiella ozaenae cholecystitis.

The authors report a case of Klebsiella ozaenae septicemia, cholecystitis and urinary tract infection in a 65-year-old morbidly obese woman with diabetes. Klebsiella ozaenae is considered a nonpathogen or colonizer rarely causing septicemia. This is the first reported case of cholecystitis due to this agent.

Intrinsic Klebsiella pneumoniae contamination of liquid germicidal hand soap containing chlorhexidine.

We describe intrinsic contamination with Klebsiella pneumoniae occurring during the manufacture of germicidal hand soap, labeled as containing 2% chlorhexidine, used throughout a 350-bed community medical center. A 3-year retrospective study failed to find evidence of increased incidence of clinical isolates of this strain.

Chlorhexidine resistance in antibiotic-resistant bacteria isolated from the surfaces of dispensers of soap containing chlorhexidine.

Bacterial contamination with pan-resistant Acinetobacter and Klebsiella, multidrug-resistant Pseudomonas, and methicillin-resistant Staphylococcus aureus (MRSA) was noted on the surfaces of dispensers of hand soap with 2% chlorhexidine. Gram-negative isolates could multiply in the presence of 1% chlorhexidine. In contrast, MRSA was inhibited in vitro by chlorhexidine at concentrations as low as 0.0019%.
