Transarterial embolization for an infected internal iliac artery aneurysm without recurrence for a long period: A case report.

We report an 85-year-old man who underwent transarterial embolization (TAE) for an infected internal iliac artery aneurysm. The patient presented with fever and left lower abdominal pain. Computed tomography (CT) revealed the expansion of a left internal iliac artery aneurysm. We planned surgical treatment for an infected internal iliac artery aneurysm; however, the patient's age and general condition made the surgery high-risk. Therefore, we performed emergency TAE. The patient was administered antibiotics for 4 weeks and discharged on day 33 after the procedure with good progression. A 3-year follow-up CT scan showed aneurysm reduction and no recurrent infections. This case report highlights that TAE can be a treatment option for patients with an infected artery aneurysm.

Anorexia Nervosa With Intermittent Fever Due to Diet-Induced Thermogenesis: A Case Report.

Diet-induced thermogenesis, influenced primarily by protein intake, generates energy from food. Herein, we present the case of anorexia nervosa in a 30-year-old woman, who developed intermittent fever while transitioning from continuous to intermittent tube feeding, with an increase in protein intake. Extensive investigations ruled out infection- or drug-related causes, indicating that intermittent fever resulted from diet-induced thermogenesis due to high protein administration. Recognizing the potential for diet-induced thermogenesis in cases of fever during tube feeding is crucial to avoid unnecessary antibiotic use and prevent the discontinuation of essential medications.

Prevalence of Drug Fever among Cases of Nosocomial Fever: A Systematic Review and Meta-analysis.

Objective Drug fever is defined as a fever that temporally coincides with the start of a culprit drug and disappears after discontinuation of the drug. It is a common cause of nosocomial fever, which refers to a fever that develops beyond the first 48 h after hospital admission. However, the exact prevalence of drug fever among cases of nosocomial fever is unclear, as is the variation in prevalence depending on the clinical setting and most common causative drugs. Methods PubMed MEDLINE, Dialog EMBASE, Cochrane Central Register of Controlled Trials, World Health Organization International Clinical Trials Registry Platform, and ClinicalTrials.gov were systematically searched. Studies that reported the prevalence of drug fever in patients with nosocomial fever were included. Two of the four reviewers conducted independent assessments of the inclusion, data extraction, and quality. Pooled adjusted odds ratios were generated using a random-effects model and presented with 95% confidence intervals (CIs). Results Fifteen meta-analysis from 15 studies were included. Ten studies did not report the definition of drug fever or excluded febrile patients who were admitted to the hospital within 24-48 h. The pooled prevalence of drug fever among cases of nosocomial fever was 3.0% (95% CI, 0.6-6.8%), which was largely consistent across the settings, except for at oriental medicine hospital. Only four studies reported the causative agents, and antibiotics were the most frequently reported. Conclusions The prevalence of drug fever is low in patients with nosocomial fever. Clinicians should recognize that drug fever is a diagnosis of exclusion, even in cases of nosocomial fever.

Invasive candidiasis presenting bronchiectatic cavity as chest radiological findings: A case report.

Invasive candidiasis is rare but is associated with high mortality in immunocompromised or critically ill patients. Here, we present a case of a 55-year-old man with untreated diabetes who was diagnosed with coronavirus disease 2019 and subsequently developed invasive candidiasis. The patient presented with fever, tachycardia, and tachypnea. Chest computed tomography revealed multiple consolidations mainly distributed around the bronchovascular bundles with bronchiectatic cavity formation, which initially raised suspicion for invasive pulmonary aspergillosis. However, subsequent testing confirmed Candida albicans infection; hence, we changed the antifungal agents effective for invasive candidiasis. This improved the patient's respiratory status, and he was then successfully weaned from mechanical ventilation. This case report highlights the importance of considering invasive candidiasis in the differential diagnosis of patients with bronchiectatic cavities on chest computed tomography, particularly in immunocompromised or critically ill patients with risk factors for invasive candidiasis.
