BACKGROUND: Clear cell (hemangioblastoma-like) stromal tumor of the lung (CCSTL) is a rare pulmonary neoplasm. Recently, 9 cases of CCSTL harboring the YAP1-TFE3 gene fusion have been described, and it has been suggested that this aberration could be a characteristic feature of this tumor. CASE PRESENTATION: We here report another case of CCSTL in a 57-year-old male, which presented as a solitary lung nodule 45 mm in the greatest dimension. Microscopically, the tumor consisted of epithelioid to spindled cells with mild-to-moderate nuclear atypia, finely granular or vesicular chromatin, and small nucleoli. Nuclear indentations were a common finding. There were up to 3 mitoses per 10 HPF. The cytoplasm was slightly eosinophilic or clear. Scattered non-tumor large multinucleated cells were present. Immunohistochemically, the tumor cells showed diffuse positivity for TFE3, CD10, vimentin, and IFITM1. Other markers examined were negative, and the expression of lineage-specific markers was not found. NGS analysis revealed a fusion transcript of the YAP1 and TFE3 genes, and a pathogenic variant of the MUTYH gene. CONCLUSION: Our finding supports the recent data suggesting that CCSTL represents a distinct entity characterized by the recurrent YAP1-TFE3 fusion.

BACKGROUND: The aim of this study was to compare plasma levobupivacaine concentrations in thoracic epidural and subpleural paravertebral analgesia. METHODS: Forty-four patients indicated for open lung resection had an epidural catheter inserted preoperatively or a subpleural catheter surgically. A bolus of 0.25% levobupivacaine at a dosage of 0.5 mg × kg-1 was given after the thoracotomy closure. Plasma levobupivacaine level at 30 min was the primary outcome. Pharmacokinetic modeling was performed subsequently. Secondary outcomes included the quality of analgesia, complications, and patients'mobility. RESULTS: Plasma concentrations were similar 30 min after application-0.389 mg × L-1 in the epidural and 0.318 mg × L-1 in the subpleural group (p = 0.33) and lower in the subpleural group at 120 min (p = 0.03). The areas under the curve but not maximum concentrations were lower in the subpleural group. The time to reach maximum plasma level was similar in both groups-27.6 vs. 24.2 min. No clinical symptoms of local anesthetic toxicity were recorded. CONCLUSIONS: Levobupivacaine systemic concentrations were low in both groups without the symptoms of toxicity. This dosage should be safe for postoperative analgesia after thoracotomy.

Extravasal guide wire entrapment due to fraying during central venous catheter placement using the Seldinger technique is a rare complication, which should be resolved as soon as possible. A 68-year-old male was scheduled for open right-side decortication. After the induction of general anesthesia, an attempt was made to place a central venous line in the right subclavian vein. However, the guide wire was entrapped extravasally between the right clavicle and the first rib. The exact site was located by palpating the bend of the guide wire in the subclavian triangle and the thoracic surgeon was available. Therefore, it was decided not to try to visualize the guide wire any further and to immediately proceed with surgical removal of the guide wire. The platysma muscle was dissected allowing access to the subclavian triangle. Venotomy of the external jugular vein was performed and the entrapped guide wire was removed via the venotomy. The whole complication was resolved within 30 minutes and the primary procedure was then performed. Managing rare complications of central venous line placement requires skill, ingenuity and, sometimes, interdisciplinary cooperation, either with a radiologist or a surgeon. The decision to proceed with immediate surgical removal of the guide wire proved a right one, and, to the best of our knowledge, such a strategy has not been described in the relevant literature to date.

Hip trauma and surgery are associated with systemic inflammatory reaction. However, little evidence exists about the role of IL-6. In order to assess the inflammatory response, we evaluated white blood cell (WBC) count, C-reactive protein (CRP) and IL-6 dynamics in sequential pre- and postsurgical samples collected from 125 elderly patients (mean age 78+/-9 years) undergoing osteosynthesis (OS) for extracapsular hip fractures (n=69), hemiarthroplasty (HA) or urgent total hip arthroplasty for intracapsular fractures (UA) (n=35), and elective total hip arthroplasty for osteoarthrosis (OA) (n=21). Both preoperative CRP and IL-6 levels were higher in patients with intracapsular fractures. IL-6 levels reached peak values immediately after the surgery, while CRP peak levels were reached 48 h after the surgery. The overall inflammatory reaction was more intense in HA patients compared to the other subgroups. Independent of each other, older age and the hip fracture type affected the IL-6 response, while the CRP response depended only on the type of surgery. The abrupt increase in IL-6 immediately after the procedure suggests its involvement in the early stages of the postoperative inflammatory reaction after hip surgery. This reaction is particularly pronounced in elderly patients receiving HA.
