A Challenging Case of Miliary Tuberculosis in Pregnancy.

Miliary tuberculosis (TB) is an uncommon yet severe condition that can pose substantial risks to pregnant women and their unborn child. This case study describes a 22-year-old pregnant female at 23 weeks of gestation presented with breathlessness, fever accompanied by chills, dry cough, and loss of appetite. With no significant comorbidities, her initial symptoms were inconclusive, leading to her initial diagnosis as a case of pyrexia of unknown origin.

Cat scratch disease in children with nocturnal fever: A case report.

Background: Cat scratch disease (CSD) is the most common human infection caused by (). The main manifestation is self-limited lymphadenopathy that primarily affects adolescents, and typically resolves without treatment within 2-4 months. However, individuals with compromised immune systems or immunodeficiency require specific antibacterial therapy following diagnosis.

Acute Hemorrhagic Rectal Ulcer Presenting With Severe Lower Gastrointestinal Bleeding: A Case Report of an Emerging Entity.

Acute hemorrhagic rectal ulcer (AHRU) is a rare but potentially life-threatening condition. We present the case of a 74-year-old man who developed sudden massive hematochezia and hypotension during hospitalization for fever of unknown origin. He was known to have alcohol-related liver cirrhosis, hypoalbuminemia and coronary artery disease (CAD) and was on daily aspirin.

[Fever in adults].

Fever is an important and common symptom. The science of fever is as old as humanity itself. Fever is often associated - by patients and healthcare professionals - with the need for antipyretics and antibiotics and can cause uncertainty and anxiety.

Intravascular Large B-cell Lymphoma Associated With Hemophagocytosis as a Cause of Fever of Unknown Origin: A Review of Literature.

A 53-year-old woman was hospitalized due to a fever of unknown origin for three weeks. Given the presence of fever and fatigue, the laboratory findings, and a bone marrow biopsy confirming hemophagocytic lymphohistiocytosis (HLH), a hematological malignancy was suspected. Peripheral lymphocytic typing, bone marrow biopsy, and imaging could not identify an underlying cause of HLH.

A Pathological Diagnosis Method for Fever of Unknown Origin Based on Multipath Hierarchical Classification: Model Design and Validation.

Background: Fever of unknown origin (FUO) is a significant challenge for the medical community due to its association with a wide range of diseases, the complexity of diagnosis, and the likelihood of misdiagnosis. Machine learning can extract valuable information from the extensive data of patient indicators, aiding doctors in diagnosing the underlying cause of FUO.

Objective: The study aims to design a multipath hierarchical classification algorithm to diagnose FUO due to the hierarchical structure of the etiology of FUO.

Overlap of Adult-Onset Still Disease and Kikuchi-Fujimoto Disease: A Case Report and Literature Review.

Kikuchi-Fujimoto disease (KFD) and adult-onset Still disease (AOSD) are two rare conditions whose association poses a significant diagnostic challenge. KFD is characterized by subacute necrotizing lymphadenitis of unknown etiology, primarily affecting young adults, and often presents with fever and posterior cervical lymphadenopathy. AOSD is a systemic inflammatory disorder of unclear origin, defined by high-spiking fever, lymphadenopathy, hepatosplenomegaly, hyperferritinemia, and leukocytosis.

Severe hypertransaminasaemia during the acute hepatitis of unknown origin alert of 2022.

Introduction: The impact of acute severe hepatitis of unknown origin in children (SHIC) subject to a medical alert in 2022 medical alert is poorly understood.

Materials And Methods: Observational study of the incidence, aetiology and clinical presentation of acute hypertransaminasaemia (HTRA) with laboratory values in the severe range (ALT and/or AST ≥ 500 U/L) in paediatric patients (age 0 to 16 years) in one health care zone from 2012 to 2022, comparing the periods of the SHIC alert and the SARS-CoV2 pandemic with previous years.

Results: The incidence of severe HTRA of any cause was 195.

[PET/CT MOLECULAR CELL IMAGING OF ACUTE PYELONEPHRITIS IN THE DIAGNOSIS OF FEVER OF UNKNOWN ORIGIN].

In addition to tumor imaging, advanced high-tech PET/CT imaging is increasingly used to elucidate the underlying causes of fever of unknown origin caused by various inflammatory processes, including pyelonephritis. Two clinical cases of whole-body PET/CT with 18F-FDG glucose, which allowed to visualize the molecular and cellular features of acute pyelonephritis as the cause of fever of unknown origin, are presented in the article. The scientifically based mechanisms of this process and the reliability of the results are discussed.

Chronicles from the Nest: A Case of Psittacosis in India.

Psittacosis is a rare zoonotic disease caused by a gram-negative obligate intracellular bacterium , which is transmitted through contact with infected birds. It comprises approximately 1% of all community-acquired pneumonia cases. However, this can be just the tip of the iceberg pertaining to the lack of routine testing and awareness of this disease entity, thereby requiring a high index of suspicion for its diagnosis.

Fever management in children and insights into fever of unknown origin: a survey among Italian pediatricians.

Background: Fever is a common symptom in children, but despite existing guidelines, pediatricians may not fully apply recommendations. Fever of Unknown Origin (FUO) is generally referred to as an unexplained prolonged fever. However, a standardized FUO definition and management is missing.

Gingival Necrosis Associated with Septic Shock of Unknown Origin in Patient with Systemic Lupus Erythematosus: A Case Report.

A 38-year-old woman with a history of systemic lupus erythematosus presented at our university hospital with fever, fatigue, and oral pain and was urgently admitted based on a diagnosis of septic shock. Initially, dental infection was suspected based on the symptoms and clinical presentation of purpura accompanied by severe tenderness along the marginal gingiva in the maxilla and mandible. However, subsequent investigations, including an oral examination, radiographic studies, and blood cultures, ruled out dental infection as the cause of the septic shock.

Retrospective study on clinical value and optimal use of [F] FDG PET/CT for inflammation of unknown origin in Japanese patients.

Despite advancements in medical technology, the challenges of diagnosing fever of unknown origin (FUO) and inflammation of unknown origin (IUO) persist. Positron emission tomography/computed tomography (PET/CT) has been used to assess these conditions; however, it is unclear which patients most benefit from this approach. This study aimed to assess the clinical value and optimal use of fluorine-18-labelled-fluorodeoxyglucose (F-FDG)-PET/CT in patients with FUO/IUO.

Clinical impact of ceftazidime/avibactam on the treatment of suspected or proven infections in a large cohort of patients with haematological malignancies: a multicentre observational real-world study.

Objectives: To evaluate clinical impact of ceftazidime/avibactam on treating infections due to MDR Gram-negative bacteria in patients with haematological malignancies (HMs).

Methods: We conducted a retrospective, observational study at 17 Italian haematological wards that included patients with HMs receiving ceftazidime/avibactam for the treatment of suspected or proven infections. The primary endpoint was all-cause mortality 30 days after infection onset.

Suspected contained rupture of a coronary artery aneurysm followed by a re-rupture: a case report.

Background: Most coronary artery aneurysms (CAAs) are clinically asymptomatic and are only detected incidentally during cardiac imaging. However, CAAs can cause fatal complications such as cardiac tamponade following a rupture. Reports of contained ruptures of CAAs are limited.

Clinical Presentation of Cat Scratch Disease in Pediatric Patients-A Single-Center Study.

Objective: Cat scratch disease (CSD) is the infectious disease caused by Bartonella henselae. Its typical presentation is regional lymphadenopathy. Also it may present with symptoms related to involved organs or disseminated disease with fever of unknown origin (FUO).

A Nomogram-Based Prognostic Model for Lymphoma Patients Initially Presenting with Fever of Unknown Origin.

Background: Patients with lymphoma who present with fever of unknown origin (FUO) as an initial symptom lack specific clinical feature analysis, prognostic factor analysis, and existing prognostic models. We aim to create a prognostic model for these patients to improve prognosis and risk assessment.

Methods: A total of 555 lymphoma patients with FUO as initial symptom studied at Huadong Hospital affiliated with Fudan University.
