Peritoneal dialysis (PD) confers many advantages, including a better quality of life for children with end-stage renal disease; however, the procedure is associated with several complications, including pleuroperitoneal leaks. Here, we report an unusual case of hydrothorax caused by long-term PD in a child, which was further complicated by pneumonia. A 9-year-old boy who had received CAPD for 22 months presented with dyspnea, swelling, and increased body weight. Chest tube drainage yielded 500 mL of transudative fluid. Computed tomography peritoneography revealed increased outflow from the peritoneum to the pleural cavity. PD was suspended, and hemodialysis (HD) was initiated. Video-assisted thoracoscopic surgery was performed; however, because the patient had pneumonia during hospitalization, pleural adhesions with a septated appearance occurred. This resulted in difficulties identifying pleuroperitoneal fistula (PPF). Right pleural effusion resolved following pleurodesis using bleomycin. Ambarsari et al.: Effective Management of PD-Associated Hydrothorax in a Child 19Regular HD was performed for 10 weeks, and PD was subsequently reinitiated. There was no recurrence of hydrothorax during long-term follow-up. We suspect that the underlying mechanism of hydrothorax in our patient was associated with a PPF that formed either due to a congenital diaphragmatic defect or an acquired defect, resulting in dialysate leakage. Our case demonstrates that a temporary switch from PD to HD, accompanied by pleurodesis, may help resolve hydrothorax that occurs as a complication of long-term PD.

Background: Descending necrotizing mediastinitis has been known to be a life-threatening condition. It is most likely to be lethal without a prompt diagnosis and aggressive surgical management. In the surgical management of this subset of mediastinitis, a debate remains as to whether a transthoracic incision should be mandatory in addition to cervical approach. Methods: This is a single-center retrospective study performed at Cipto Mangunkusumo Hospital from January 2012 to June 2014. Patients with descending necrotizing mediastinitis were treated with broad-spectrum antibiotics and with cervical and transthoracic approach (via sternotomy) surgical debridement. Results: There were 16 consecutive cases of descending necrotizing mediastinitis. One patient did not undergo sternotomy and was ruled out from the study. The mean intensive care unit stay was 26.4 days, with a mean hospital stay of 46.7 days. There were three mortality cases reported and a total of three cases that needed reoperation. There was neither post-operative sternal dehiscence nor osteomyelitis found. Conclusion: Considering there are no post-operative sternal-related infection reported in this study, sternotomy should be considered as an access in descending necrotizing mediastinitis management. In the three mortality cases reported, two patients came with preoperative sepsis and one had iatrogenic subclavian artery injury.

Primary cardiac tumors (PCTs) are extremely rare entities. More than half of PCTs are benign, with myxoma being the most common tumor. Generally, simple tumor resection is the treatment of choice for benign PCTs since it has promising results that yield low complication and recurrence rates. However, in the COVID-19 pandemic era, the mitigation protocols and/or concurrent COVID-19 infection should be taken into account in patient management for the best overall outcome. To our knowledge, this is the first case report of a patient with a left atrial myxoma and systemic embolism complication in the form of an ischemic stroke, with a concurrent confirmed COVID-19 delta variant infection.
