Aspergillosis is an opportunistic mycosis that generally affects the lungs. The fungus was cleared by the immune system of a healthy host. Extrapulmonary forms are very rare, and there are few reports of urinary aspergillosis. In this case report, we describe a 62-year-old woman with systemic lupus erythematosus (SLE) with complaints of fever and dysuria. The patient had recurrent episodes of urinary tract infection and several hospitalizations. A computed tomography revealed an amorphous mass in the left kidney and bladder. After partial resection of the material was referred for analysis, Aspergillus infection was suspected and confirmed by culture. Successful treatment with voriconazole was provided. Diagnosis of localized primary renal Aspergillus infection in a patient with SLE requires careful investigation due to its benign presentation and lack of associated systemic clinical features.

Meningococcemia is the infection of the blood caused by Neisseria meningitidis. Herein, we report a case of meningococcemia in an 11 months old infant who had a high-grade fever, nonblanching purpuric rash over the face and limbs, low blood pressure, tachycardia, and prolonged capillary refill time, but without neck rigidity and focal neurologic signs. He recovered after supportive care and treatment with antibiotics (intravenous ceftriaxone, vancomycin, and teicoplanin). Therefore, in a febrile, ill-looking child in shock with a nonblanching rash, meningococcal disease should be suspected. The study shows the importance of vaccination against meningococcal disease.

Cerebritis and infective endocarditis caused by Listeria monocytogenes are very rare. A 56-year-old man presented with slurring of speech and generalized body weakness of 1 week duration. He did not have any past medical history. On systemic examination, he had mild slurring of speech and facial asymmetry and was initially treated for multifocal chronic cerebral infarcts. Listeria monocytogenes was isolated from blood culture on day 5 of admission. A diagnosis of neurolisteriosis was made as contrast-enhanced-computed tomography (CECT) of the brain showed right frontal cerebritis. He was treated with intravenous benzyl penicillin. His general condition was improving until day 13 of hospitalization whereby he developed haemoptysis and severe Type 1 respiratory failure requiring reintubation. An urgent transthoracic echocardiogram revealed a large vegetation at the anterior mitral valve leaflet measuring 2.01 cm. No active arterial bleeding was seen on computed tomography angiography (CTA) of the thorax. Magnetic resonance imaging (MRI) of the brain showed evidence of right frontal cerebritis. He continued to deteriorate and succumbed to his illness after 3 weeks of hospitalization. Clinicians should be aware of such an occurrence and prompt recognition and adequate treatment are necessary in cases of Listeria monocytogenes cerebritis and infective endocarditis as both are deadly entities.

Mucormycosis is a rare but fatal disease caused by a filamentous fungus involving the nose, paranasal sinuses, and brain. These organisms usually cause severe infections in immunocompromised individuals. Granulomatous polyangiitis (GPA), also known as Wegner's granulomatosis, is a rare, aseptic necrotizing granulomatous vasculitis involving small and medium-sized vessels commonly affecting the nose, ears, lungs, and kidneys. The simultaneous occurrence of mucormycosis and GPA, two rare diseases, in the same patient is exceedingly rare. In this case study, we describe a 40-year-old woman who presented with manifestations of both GPA and mucormycosis. She was started with steroids and antifungal agents and achieved significant improvement.

Roseomonas mucosa (R. mucosa) is a pink-pigmented, aerobic, nonfermentative, slow-growing Gram-negative coccus typically isolated from the natural environment, human skin, and hospital environment. This pathogen, in most circumstances, leads to infections in immunocompromised hosts, but it may sometimes invade immunocompetent individuals. Bacteraemia is the most common form of infection caused by R. mucosa. In contrast, only two case reports have described R. mucosa-related epidural abscess formation and infective spondylitis. In this case report, we shared the history and treatment experience of a 76-year-old female who was diagnosed with infective spondylitis and epidural abscess caused by R. mucosa. She received a local transdermal injection into the lower back to relieve her back pain two months before symptom onset, which was considered to be associated with this infection episode. After admission to the hospital, neurosurgeons performed emergent decompression and debridement. She was treated with intravenous ceftriaxone for four weeks, followed by oral ciprofloxacin for another eight weeks. The patient recovered well without any sequelae and had no relapse of infection at least six months after the end of treatment. In addition to the case report, we reviewed the literature for reported cases caused by R. mucosa. Our experience suggests that clinicians should include R. mucosa as one of the possible healthcare-associated pathogens among individuals who have undergone transdermal procedures. We believe that this article will help clinicians better recognize R. mucosa infection.

We describe the case of a 13-year-old girl who presented with a new-onset seizure and fever and subsequently developed severe cardiac dysfunction, coronary artery dilation, and shock due to the surprising diagnosis of multisystem inflammatory syndrome in children (MIS-C). Although the clinical entity we now call MIS-C was first mentioned in the medical literature in April 2020, the full picture of this disease process is still evolving. Neurologic involvement has been described in cases with MIS-C; however, seizures are not a typical presenting symptom. Additionally, because children infected with SARS-CoV-2 are often asymptomatic, a documented preceding COVID-19 infection might not be available to raise suspicion of MIS-C early on. Febrile seizures, meningitis, and encephalitis are childhood illnesses that pediatricians are generally familiar with, but associating these clinical pictures with MIS-C is uncommon. Given the possibility of rapid clinical cardiogenic decline, as seen in our patient, a prompt diagnosis and appropriate monitoring and treatment are of utmost importance. This case report aims to raise awareness that new-onset seizures with fevers can be early or the first presenting symptoms in children with MIS-C, and further workup and close monitoring may be required.

A 31-year-old male was admitted to the hospital because of fever for 2 days. He also had chills, headaches, muscle aches, fatigue, and diarrhea. His vital signs were stable. Dengue virus nonstructural protein 1 (NS1) antigen was positive. Laboratory tests were significant for thrombocytopenia of 67.000/mm³ and high hematocrit of 45%. On the fifth day of the onset of fever, he experienced sudden epigastric pain. Laboratory results showed elevated serum amylase and lipase. Noncontrast abdominal CT findings were consistent with acute pancreatitis, Balthazar grade D. The patient was managed with supportive care and bowel rest. Two days later, his condition became stable, and he was discharged without complications.

Dengue viral infection is considered endemic in Ecuador. It is more frequent during winter, caused by an RNA virus in the Flavivirus group. Its presentation can range from an asymptomatic state to hemorrhagic fever with shock signs. Acute pancreatitis could be a rare form of acute abdomen presentation associated with dengue virus infection. This case illustrates a 26-year-old man who presents to the hospital with cramp-like pain in the epigastrium and radiation to the right upper quadrant, accompanied by nausea and vomiting. He also endorsed additional symptoms such as throbbing-like headache, myoarthralgias, and fever of 40.4°C (104.72°F). Laboratory tests revealed elevated hematocrit, thrombocytopenia, elevated pancreatic enzymes, transaminitis, elevated alkaline phosphatase (ALP), and gamma-glutamyl transferase (GGT). Ultrasonography of the abdomen revealed hepatic steatosis, free fluid in the abdominal cavity, and small bilateral pleural effusions. Additional testing revealed IgM and IgG antibodies positivity to dengue virus. The patient was treated conservatively with intravenous (IV) fluid hydration and bowel rest. Acute pancreatitis should be considered when a patient presents with a suspected acute abdomen in the emergency department, and a detailed medical history is necessary to make a correct approach to the differential diagnosis.
