Frontiers in Pediatrics 2024This study sought to analyze the value of point of care ultrasound (POCUS) in early diagnosis and monitoring of deep abscess in newborns.
OBJECTIVE
This study sought to analyze the value of point of care ultrasound (POCUS) in early diagnosis and monitoring of deep abscess in newborns.
METHODS
Retrospective analysis of the clinical data of two newborns admitted to the Neonatal Intensive Care Unit (NICU) of our hospital and diagnosed with deep abscess of the newborn. Combined with literature analysis, the value of POCUS in early diagnosis and monitoring of deep abscess of the newborn was evaluated.
RESULTS
The two newborns reported in this article were all admitted to NICU due to" "fever". POCUS was used to assist in early diagnosis of "liver abscess" and "lung abscess". Subsequently, POCUS was used to monitor lesion changes and adjust treatment plans. All patients were cured and discharged with a good prognosis.
CONCLUSIONS
Deep abscesses in newborns are very rare and often life-threatening, but apart from fever, they often have no specific clinical manifestations and are easily misdiagnosed or missed. POCUS, as a bedside auxiliary examination tool, has high accuracy, radiation free, non-invasive, and convenient, and has high diagnostic and monitoring value in early diagnosis and monitoring of deep abscess in newborns.

Lung abscess and empyema represent significant complications of community-acquired pneumonia, particularly in patients with comorbidities such as obesity, asthma, and vaping (which can lead to vaping-associated lung injury). While these conditions rarely occur simultaneously, their coexistence significantly escalates both mortality and morbidity. Management strategies typically involve a multidisciplinary approach, incorporating diagnostic evaluation through imaging, administration of antibiotics, and often surgical drainage. While antibiotics are fundamental in treating both conditions, empyema management almost invariably necessitates surgical intervention. Initial imaging usually involves plain radiographs, although ultrasound and lung CT scans provide heightened sensitivity and fluid characterization. Here, we present the case of a 24-year-old morbidly obese patient with a history of bronchial asthma initially presenting with community-acquired pneumonia, which subsequently deteriorated into lung abscess and empyema, ultimately requiring surgical intervention.

INTRODUCTION
Pulmonary sarcomatoid carcinoma is a very rare primary tumor of the lung. Although usually aggressive, these tumors have not been described previously to invade through the diaphragm into the liver. We present a patient with a pulmonary sarcomatoid carcinoma with transdiaphragmatic spread into the dome of the liver.
PRESENTATION OF CASE
An 82-year-old female with a lifetime non-smoking history presented with generalized fatigue, fever, night sweats, cough, and pleuritic chest pain. She had recently traveled to the western United States. Additionally, she had recently undergone periodontal deep cleaning with no peri-procedural antibiotics. Laboratory testing was significant for a leukocytosis of 13.5 white blood cells per microliter and a negative viral panel. Computed tomography and magnetic resonance imaging revealed a large heterogeneous mass extending from the right pulmonary hilum through the diaphragm. Although initial radiology reports suggested hepatic abscess, percutaneous fine needle aspiration was performed. Biopsy revealed pulmonary sarcomatoid carcinoma. She was begun on systemic treatment.
DISCUSSION
Pulmonary sarcomatoid carcinoma can exhibit transdiaphragmatic invasion into the liver. This clinical situation can easily be confused with a hepatic abscess, but suspicion should remain for abscess. Clinical suspicion for neoplasm should warrant biopsy when technically possible.
CONCLUSION
Although hepatic abscesses can exhibit transdiaphragmatic spread into the chest, pulmonary sarcomatoid carcinoma can also invade the abdomen. Biopsy should be performed during the evaluation and workup of the patient.

BACKGROUND
Melioidosis is an infection caused by , a Gram-negative bacterium. It is a disease endemic to Southeast Asia and northern Australia although its global incidence has been rising. It most commonly infects people with certain identified risk factors such as diabetes, alcoholism, thalassemia, and underlying chronic disease involving lungs, kidney and liver. This bacterium is capable of producing a wide array of clinical manifestations ranging from asymptomatic disease to localised infections such as in the lung, bone or skin to disseminated infection.
CASE DESCRIPTION
This is a case, from United Arab Emirates, of a 40-year-old male recently diagnosed with diabetes who presented with multiple abscesses and was eventually diagnosed with disseminated melioidosis. He was treated successfully with antibiotics and drainage of abscesses.
CONCLUSION
In non-endemic regions, melioidosis can be easily missed in common diagnostic approaches. This gap of awareness could delay the diagnosis and allow further deterioration of the patient due to complications. Thus, case reports like this can enlighten internists about changing incidences and complexity of clinical presentations, thus preparing them to better handle such patients in the future.
LEARNING POINTS
Owing to its considerably rare incidence in non-endemic regions including the United Arab Emirates, melioidosis can easily be overlooked or misdiagnosed.Moreover, due to similarity with multiple other diseases and infections as well as significant absence from standard medical curricula, melioidosis is rarely on the differential list of an internist.This report aims to enhance awareness and alertness to aid earlier detection and avoid severe complications.

Nephropleural fistula, a rare complication of percutaneous nephrolithotomy (PCNL), occurred in a 45-year-old male with adult autosomal dominant polycystic kidney disease (ADPKD). The patient had undergone right PCNL in 2021 and 2023 and presented to the emergency department with symptoms of fever, breathlessness, and cough lasting one week. Imaging studies, including chest radiograph and contrast-enhanced computed tomography (CECT) of the abdomen and pelvis, revealed gross right pleural effusion, right perinephric abscess, multiple renal cysts, right renal calculi and right ureteric calculi causing severe right hydronephrosis and proximal hydroureter. The imaging also confirmed a nephropleural fistula, with the right kidney's perinephric abscess communicating with the right pleura via the right subhepatic space. Subsequent thoracic ultrasound showed a large effusion of 1500ml with underlying lung collapse. Diagnostic thoracocentesis confirmed empyema, necessitating immediate tube thoracostomy. CT intravenous urography confirmed a non-functioning right kidney. The perinephric abscess was drained with a PCNL tube and meanwhile, pleural fluid and perinephric abscess isolated Klebsiella pneumonia on cultures. The patient received parenteral antibiotics and intravenous fluids and had an intercostal drain and PCNL tube in place for drainage. A right nephrectomy was recommended due to the non-functioning right kidney and the patient is awaiting the procedure.

Appendicitis is an inflammation of the vermiform appendix (located near the base of the cecum). A lung abscess is a cavitary lesion containing necrotic lung tissue or an infected fluid component. It mainly occurs as a result of lung parenchymal disease. The patient was a 25-year-old male who first presented with a 1-week history of productive cough and chest pain associated with low-grade fever. He was diagnosed with a lung abscess as a complication of perforated retro cecal appendicitis. We report this in consideration of reducing the challenge of delay in diagnosis of this rare complication, and to avoid mistreatment specifically when the patient's chest x-ray resembles empyema. Additionally, we encourage doing further studies on this topic.

OBJECTIVE
To describe ventilator-associated pneumonia (VAP) recurrence in COVID-19 patients requiring extracorporeal membrane oxygenation (ECMO) support, and to evaluate the impact of antimicrobial treatment duration of the first VAP episode on VAP recurrence.
METHODS
Adult patients with COVID-19 severe pneumonia on ECMO admitted between March 2020 and January 2022 were retrospectively included. Primary outcome was incidence of VAP recurrence, and secondary outcome was the impact of duration of antimicrobial treatment on VAP recurrence.
RESULTS
Among the 252 included patients, 226 (90%) developed a first VAP. Sixteen had lung abscess and were excluded, leaving 210 patients. VAP recurrence occurred in 172 patients (82%), with a median (IQR) time from first VAP to recurrence of 10 (7-13) days. Pseudomonas aeruginosa and Enterobacteriaceae were respectively responsible for 28% and 52% of first VAP, and 51% and 62% of first recurrence episodes. Among the 210 patients with a first VAP, 158 (75%) received a short course of antibiotics [< 8 days, median (IQR) duration 6 (5-7) days] and 52 (25%) received a prolonged course of antibiotics [≥ 8 days, median (IQR) duration 9 (8-10) days]. Estimated cumulative incidence of VAP recurrence, taking into account death and extubation as competing risks, was not different in patients with short- and prolonged-antimicrobial treatment.
CONCLUSIONS
In patients with severe Covid-19-ARDS requiring ECMO support, VAP recurrence occurs frequently, with Enterobacteriaceae and Pseudomonas aeruginosa as predominant causative microorganisms. An antimicrobial treatment of ≥ 8 days for the treatment of first VAP episode did not reduce the risk of VAP recurrence, as compared to shorter duration.

bacille Calmette-Guérin (BCG) is the most effective intravesical immunotherapy for non-muscle invasive bladder cancer (NMIBC), administered after its transurethral resection. Although its instillation is generally well tolerated, BCG-related infectious complications may occur in up to 5% of patients. Clinical manifestations may arise in conjunction with initial BCG instillation or develop months or years after the last BCG instillation. The range of presentations and potential severity pose an imminent challenge for clinicians. We present a case of an isolated subcutaneous chest wall abscess in an immunocompetent 52-year-old patient nearly two years after intravesical BCG instillation for NMIBC, an absolute rarity. As the enlarging chest wall tumor may be misinterpreted as malignancy, its expedient diagnosis and prompt treatment are of critical importance.

Review
BACKGROUND
Crizotinib, an oral first-generation tyrosine kinase inhibitor (TKI), is superior to systemic chemotherapy for the treatment of non-small cell lung cancer (NSCLC) with positive rearrangement of anaplastic lymphoma kinase (ALK). However, an increased incidence of renal and hepatic cysts has been reported in the patients on crizotinib treatment.
CASE PRESENTATION
Here, we describe a case of a 71-year-old Chinese women developed multiple cystic lesions in kidney and liver during crizotinib treatment for the primary and metastatic NSCLC. The renal and hepatic cysts were noted by CT scan 3 months after crizotinib treatment, which were spontaneously and significantly regressed after stopping crizotinib.
CONCLUSIONS
Based on literature review and our experience in this case report, we concluded that crizotinib-associated renal cyst (CARCs) has features of malignancy and abscess in radiographic imaging, and thus, pathological confirmation is necessary to avoid inappropriate treatment decision. In addition, to benefit the patients with progress-free survival (PFS), switching from crizotinib to alectinib is recommended for the treatment of NSCLC patients who developed CARCs.

Allergic reactions to drugs caused by piperacillin-tazobactam are common in clinical practice. However, we also found a few cases of drug-induced hypersensitivity syndrome (DiHS)/Drug reaction with eosinophilia and systemic symptoms (DRESS) caused by piperacillin-tazobactam in our clinical work. We report a case of a 60-year-old female patient who was treated with piperacillin-tazobactam anti-infective therapy after the diagnosis of hematogenous lung abscess, developed fever, rash, and blood abnormalities after 26 days of application, and was later diagnosed as DIHS, which was improved after the administration of glucocorticoid and anti-allergic drugs. In addition, we also retrospectively analyzed 17 cases of DiHS caused by piperacillin-tazobactam from the PubMed databases between March 1980 and September 2023. The majority of the patients had an incubation period of more than 14 days, and the common clinical features included elevated eosinophil count/percentage, fever, rash, liver damage, and lymph node enlargement. After treatment with topical or systemic glucocorticoids, 16 of the 17 patients improved and one died because of the underlying condition. The clinical features of DiHS were diverse and included a long incubation period, skin rash, elevated eosinophils, and impaired organ function. Since some patients have atypical clinical features, clinicians should raise awareness of the disease, recognize these features early, and treat them promptly.
