Coadministering two different classes of antibiotics as empirical therapy can be critical in treating healthcare-associated infections in hospitals. Herein, we report a case of acute kidney injury (AKI) caused by coadministration of vancomycin with high-dose meropenem that manifested as a rapid increase in serum creatinine levels and an associated increase in vancomycin trough concentrations. The patient was diagnosed with meningioma at 50 years and was followed up regularly. The patient underwent surgery and antibiotic treatment between 63 and 66 years for suspected meningitis and pneumonia. Coadministration of vancomycin with high-dose meropenem (6.0 g/day) caused AKI; however, no AKI occurred when vancomycin was administered alone or with a low dose of meropenem (1.5 or 3.0 g/day). To our knowledge, this report is the first to show that administering different dosages of meropenem in combination with vancomycin may contribute to the risk of developing AKI. We suggest that coadministered vancomycin and high-dose meropenem (6.0 g/day) may increase the risk of AKI. Our report adds to the limited literature documenting the coadministration of vancomycin with varying doses of meropenem and its impact on the risk of AKI and highlights the importance of investigating AKI risk in response to varying dosages of meropenem when it is coadministered with vancomycin.

Fusobacterium nucleatum (F. nucleatum) is a commensal Gram-negative anaerobic bacterium that lives in the oral cavity and gastrointestinal tract of humans. While it is a regular resident of the human oral cavity, F. nucleatum has been implicated in various infections and inflammatory conditions. This case report highlights an unusual association between F. nucleatum and isolated superior mesenteric vein (SMV) thrombosis.

We present a case of a Philippine woman in her late twenties, diagnosed with spinal tuberculosis after surgical intervention due to medullary compression. The diagnosis was preceded by four months of unexplained back pain. Differential diagnoses included ulcer, liver-gallbladder disease, musculoskeletal causes, and cancer. This case highlights the importance of considering tuberculosis as a differential diagnosis in patients from high-endemic areas to avoid diagnostic delay and the risk of disease progression.

Over 200 different serogroups of Vibrio cholerae based on O-polysaccharide specificity have been described worldwide, including the two most important serogroups, O1 and O139. Non-O1/non-O139 V. cholerae serogroups generally do not produce the cholera-causing toxin but do sporadically cause gastroenteritis and extra-intestinal infections. Recently, however, bloodstream infections caused by non-O1/non-O139 V. cholerae are being increasingly reported, and these infections are associated with high mortality in immunocompromised hosts. We describe a case of non-O1/non-O139 V. cholerae bacteremia in a patient with autoimmune pancreatitis and stenosis of the intra- and extrahepatic bile ducts. The clinical manifestations of bacteremia were fever and mild digestive symptoms. The blood cultures showed V. cholerae, which was identified as a non-O1, non-O139 serogroup by slide agglutination tests and PCR. The bloodstream infection of the patient was likely caused by the consumption of contaminated seafood at a banquet. The patient recovered after the administration of a third-generation cephalosporin. Non-O1/non-O139 V. cholerae infection presents with or without gastrointestinal manifestations; close attention should be paid to the possibility of disseminated non-O1/non-O139 V. cholerae infection in high-risk patients.

Introduction: Potts disease is extrapulmonary skeletal tuberculosis mostly affecting the thoracolumbar spine. It destroys the disc space, adjacent vertebral bodies, and spinal elements, leading to cord compression and paraplegia.

Methods: This is a case report study of a 29-month-old toddler who presented to our hospital with bilateral lower limb weakness.

Results: On clinical, laboratory, and radiological examination, she was diagnosed with Pott's spine, started on antitubercular therapy, and planned for surgery in her follow-up.

Conclusion: Tuberculosis of the spine is still prevalent in developing countries, mainly in children. Complications of the disease can be devastating because of its ability to cause bone destruction, spinal deformity, and paraplegia. So, in a tuberculosis-endemic region, clinical suspicion should be there for Potts disease when a child presents with paraplegia of the lower limbs. Children can develop tuberculosis which can spread to the spine despite vaccination. The prognosis of spinal tuberculosis is improved by early diagnosis and rapid intervention.

Lung is the second most common locationof cystic echinococcosis (CE), after the liver. Diagnosis of lung CE is often incidental, and clinical manifestations depend on the location and size of the cyst, the most common being chest pain, shortness of breath, expectoration of fragments of endocyst, and haemoptysis. Surgery is the primary treatment, with a minor role for medical therapy. Delayed diagnosis and treatment may have important consequences. We present a case of lung CE in whichsurgical treatment was delayed due to the first wave of COVID-19. Since surgery could not be performed immediately, the patient was kept on albendazole and the cyst stage moved from CE1 to CE3a, to CE4, eventually requiring a more aggressive pericystectomy instead of the commonly performed endocystectomy. The clinical and imaging characteristics of a rare CE4 cyst of the lung are reported.

Acute pericarditis is an inflammatory condition involving the pericardium, the double-layered sac that surrounds the heart. It is characterized by chest pain, typically pleuritic and sharp, along with other clinical and laboratory findings indicative of pericardial inflammation. While acute pericarditis following influenza vaccination is rare, it has been reported in medical literature. The relationship between vaccinations, including the influenza vaccine, and pericarditis is particularly interesting, as it has implications for public health and vaccination programs. Understanding the pathophysiological mechanisms behind vaccine-induced pericarditis and recognizing the clinical presentation are essential for healthcare professionals to diagnose, manage, and educate patients appropriately.

In this case, we present an immunocompetent patient who had a wound infection secondary to Aspergillus fumigatus after undergoing a neurosurgical procedure that was complicated by an epidural abscess. The patient was treated with voriconazole and responded favorably. We highlight the need for awareness of the possibility of an Aspergillus infection in people without any obvious immunocompromise and advocate for the inclusion of this opportunistic fungus in the workup of postneurosurgical infections and dura-based collections. A brief review of relevant literature is also included.

Cat-scratch disease (CSD) is a self-limited zoonotic infection transmitted by felines caused by the Gram-negative bacillus Bartonella henselae. It usually presents with lymphadenopathy and constitutional symptoms that resolve within eight weeks, with, or without antibiotic treatment. The diagnosis is made by serology, molecular diagnosis in a biopsy, or a positive culture. The recurrence or reactivation of B. henselae has rarely been reported. We present the case of a 45-year-old man with a history of CSD two years before who presented to the clinic with groin lymphadenopathy. The patient had a history of close contact with felines though no known risk exposure was reported. The diagnosis was made with a positive serology suggestive of recent infection along with histopathological changes suggestive of CSD. Subsequently, azithromycin was administered with complete resolution of symptoms.

Background: Tuberculosis is a bacterial infection that is caused by Mycobacterium tuberculosis. Tuberculosis has arguably been the largest killer of humans historically, and it remains one of the most important infectious causes of death in the world. Tuberculosis can be classified into different forms and it manifests as pulmonary and out pulmonary, respectively, in 85% and 15% of cases. Only a few cases of tuberculosis with abdominal wall involvement have been reported. Case Presentation. Herein, we present a 27-year-old Persian woman, presented with asymmetric abdominal bulging in the right side of the periumbilical area since 6 months before admission that has no pain or secretion. The patient was oriented and not ill or toxic in general appearance. Vital signs were within normal ranges. An abdominal physical examination revealed a mobile, well-bordered, nontender mass 3 × 3 centimeter (cm) in diameter palpated in the right periumbilical area. The patient underwent surgery which revealed a cystic lesion that was carefully resected. In histopathology examination of the specimen resection, tuberculosis was confirmed.

Conclusion: We report a rare case of extrapulmonary tuberculosis that was identified at the abdominal wall. Due to the high number of cases of TB and the development of extrapulmonary forms that can present in an unusual location as an abdominal wall which are difficult to diagnose, it is very important to keep in mind the differential diagnosis of tuberculosis.
