Listeria monocytogenes is an uncommon cause of illness in the general population. Meningoencephalitis is the most common central nervous system (CNS) manifestation of listeriosis. However, brain abscess represents 1-10% of all CNS listeriosis. To our knowledge, L. monocytogenes brain abscess in multiple myeloma patients has not been previously reported. Thus we report a 58-year-old male patient with multiple myeloma who developed a brain abscess due to L. monocytogenes. Due to a history of penicillin allergy, he was treated with intravenous trimethoprim/sulfamoxazole (TMP-SMX) for a total of 12 weeks, and gentamicin for the first two weeks, followed by oral therapy of TMP-SMX for a total of nine months. He is alive six and a half years after the diagnosis of myeloma with occasional brief seizures despite being on two anticonvulsants.

Introduction: Hereditary hemorrhagic telangiectasia (HHT) is an autosomal dominant vascular disease and screening to detect pulmonary arteriovenous malformations (PAVMs) is important to prevent complications. In adults, transthoracic contrast echocardiogram (TTCE) is used to screen PAVMs. In children, a conservative screening method seems to be sufficient to rule out major PAVMs and prevent them from PAVM-related complications.

Background: Nocardia are widely present in nature and considered opportunistic pathogens. They can result in hematogenous spread infection through the ruptured skin or respiratory tract when the host's immune system is compromised. Currently, 119 species of Nocardia have been identified, with 54 capable of causing infections in humans.

Hypervirulent (hvKp) has attracted increasing attention in recent years. Diabetes and serotype K1 or K2 are risk factors for invasive liver abscess syndrome including liver abscesses and the metastatic complications such as bacteremia, meningitis, endophthalmitis, and necrotizing fasciitis. Simultaneous infections of the liver, lungs, prostate, brain, and eyes are exceedingly rare.

Peritonsillar abscesses and deep neck infection are potentially serious infections among patients with chronic kidney disease (CKD), posing risks for severe complications and drawing significant public health concern. This nationwide, population-based longitudinal study (2002-2019) assessed the extended relationship between chronic kidney disease (CKD) and the likelihood of peritonsillar abscess and deep neck infection in a Korean cohort. Using a 1:4 propensity score overlap-weighted matching, we included 16,879 individuals with CKD and 67,516 comparable controls, accounting for demographic variables and comorbidities to ensure balanced group comparisons.

In recent years, an increasing number of reports have described invasive infections caused by bacteria from (SAGs). seems to be more related with pleuropulmonary infections and abscess of the brain and deep soft tissues, and it is more likely to cause suppurative and non-bacteremic infections compared to other members of the same genus. We present two clinical cases of invasive infections in pediatric patients: a liver abscess case and a pansinusitis case associated with bilateral otomastoiditis and parapharyngeal abscess complicated by acute mediastinitis, thrombophlebitis of the cavernous sinus, and thrombosis of the cranial tract of the ipsilateral jugular vein.
