Intrahepatic Gallbladder Rupture and Biloma Mimicking Pulmonary Embolism Following Orthopedic Surgery.

In this case report, a 75-year-old male with a history of coronary artery disease, type 2 diabetes, hypertension, and benign prostate hypertrophy developed postoperative fever and chest pain following left knee arthroplasty. Upon admission to the emergency department, pulmonary embolism was considered highly probable, and the patient was treated with anticoagulation and antibiotics due to diagnostic uncertainty. However, further investigations revealed a complex condition involving an intraparenchymal gallbladder rupture resulting in a biloma secondary to choledocholithiasis. The patient's history of receiving spinal anesthesia with intrathecal morphine was identified as a potential causative factor to the sphincter of Oddi constriction, leading to increased biliary pressure and gallbladder rupture. This case highlights the importance of having a broad differential diagnosis in postoperative patients, especially when the clinical presentation is atypical. With the diagnosis being confirmed, the patient underwent successful treatment, including biliary stenting, drainage of the biloma, and ultimately cholecystectomy. This case underlines the need for vigilance and a multidisciplinary approach in managing complex postoperative complications, emphasizing that clinical presentations may sometimes deviate significantly from the expected, requiring further investigation and individualized treatment.

Anti-Ro52/Anti-nuclear Matrix Protein 2 Positive Clinically Amyopathic Dermatomyositis Presented Only With Interstitial Lung Disease.

This report contemplates a unique case of clinically amyopathic dermatomyositis (CADM) that presented as interstitial lung disease. The patient was a 55-year-old woman who showed up with progressive exercise intolerance and a dry cough without muscular or dermatological clinical manifestations. Diagnostic workup and imaging revealed the presence of interstitial lung disease, and further evaluation led to a positive autoimmune panel for anti-nuclear matrix protein 2 (anti-NXP2) and anti-Ro52 antibodies, establishing the diagnosis of anti-NXP2 plus anti-Ro52 antibodies-positive amyopathic idiopathic inflammatory dermatomyositis. The patient was started on intravenous corticosteroids. She showed improvement on her chest X-ray (CXR) and was then switched to oral corticosteroids. After six months of steroid treatment, corticosteroids were stopped, and the patient was re-evaluated one month later disease relapse.

A Unique Case of Conservatively Treated Actinomyces Empyema Complicated Due to Drug Reaction With Eosinophilia and Systemic Symptoms Syndrome.

This case contemplates the unusual presentation, challenging diagnostic workup and conservative therapeutic process of a patient with Actinomyces empyema complicated along the way due to drug reaction with eosinophilia and systemic symptoms (DRESS) syndrome. The patient was a 40-year-old male, who presented with pleurodynia and fever. Laboratory exams showed elevated inflammatory markers and imaging revealed two biconvex fluid pockets located in the right lower lobe, from which the fluid was positive for Actinomyces meyeri. The initial conservative process with intravenous antibiotics and successful drainage with intrapleural fibrinolysis improved our patient. However, after a few days, the patient's fevers relapsed, and as regress of the empyema was discussed as a complication, he developed a maculopapular symmetrical rash of the trunk and legs accompanied by enlarged lymph nodes, eosinophilia, thrombocytopenia, and atypical lymphocytes. The diagnosis of DRESS syndrome due to antibiotic therapy for actinomyces empyema was established and a balance between bactericidal and immunosuppression medication had to be found. Fortunately, the patient withstood prolonged antibiotic therapy and got fully treated without any relapses.

Familial Mediterranean Fever in a 28-Year-Old Male Presented as a Painless Massive Pleural Effusion.

This case describes the first patient with familial Mediterranean fever (FMF) with massive left pleural effusion as the first clinical manifestation, to whom a video-assisted thoracoscopic surgery was performed to support the diagnosis. The patient was a 28-year-old male, who presented with dry cough and dyspnea but no fever. The lab findings showed hypoxemia (partial pressure of oxygen = 65 mm Hg) accompanied by elevated inflammatory markers, including C-reactive protein at 7 mg/dl (<0.5 mg/dl), erythrocyte sedimentation rate of 46 mm/h (<20 mm/h), and serum amyloid at 56.7 mg/L (<10 mg/L). X-ray indicated the left pleural effusion was part of a bilateral recurrent painless pleuritis, as the right pleural thickening implied. Numerous biopsies were taken during the thoracoscopy, and the histopathology examination reported non-specific fibrous pleurisy. Colchicine administration, at first empirically for upcoming pericarditis, at the end was a significant clue for the diagnosis. Positive molecular testing for mutations in the familial Mediterranean fever (MEFV) gene contributed to the diagnosis of FMF, which was based on the Tel-Hashomer clinical criteria. The purpose of this article is hopefully to raise further awareness about patients with FMF presented with unusual manifestations of the disease.

Secondary bacterial infections are a leading factor triggering New Onset Atrial Fibrillation in intubated ICU Covid-19 ARDS patients.

BACKGROUND: Cardiac arrhythmias, mainly atrial fibrillation (AF), is frequently reported in COVID-19 patients, more often in Intensive Care Unit (ICU) patients, yet causality has not been virtually explored. Moreover, non-Covid ICU patients frequently present AF, sepsis being the major trigger. We aimed to examine whether sepsis or other factors-apart from Covid-19 myocardial involvement-contribute to elicit New Onset AF (NOAF) in intubated ICU patients. METHODS: Consecutive intubated, Covid-19ARDS patients, were prospectively studied for factors triggering NOAF. Demographics, data on Covid-19 infection duration, laboratory findings (troponin as well), severity of illness and ARDS were compared between NOAF and control group (no AF) on admission. In NOAF patients, echocardiographic findings, laboratory and secondary infection data on the AF day were compared to the preceding days and/or ICU admission data. RESULTS: Among 105 patients screened, 79 were eligible; nineteen presented NOAF (24%). Baseline characteristics did not differ between the NOAF and control groups. Troponin levels were mildly elevated upon ICU admission in both groups. Left ventricular global longitudinal strain was impaired (<16.5%) in 63% vs 78% in the two groups, respectively. The right ventricle was mildly dilated, and pericardial effusion was present in 52 vs 43%, respectively. NOAF occurred on the 18 ± 4.8 days from Covid-19 symptoms' onset, and the 8.5 ± 2.1 ICUday. A septic secondary infection episode occurred in 89.5% of the patients in the NOAF group ( vs 41.6% in the control group (p < 0.001). In fact, NOAF occurred concurrently with a secondary septic episode in 84.2% of the patients. Sepsis presence was the only factor associated to NOAF occurrence (OR 16.63, p = 0.002). Noradrenaline, lactate and inflammation biomarkers gradually increased in the days before AF (all p < 0.05). Echocardiographic findings did not change on NOAF occurrence. CONCLUSION: Secondary infections seem to be major contributors for NOAF occurrence in Covid-19 patients, probably playing the role of the "second hit" in an affected myocardium from Covid-19.
