Our results suggest that besides impaired production in the failing liver, an increased TPO degradation by platelets sequestered in the congested spleen may contribute to thrombocytopenia in cirrhotic patients.

Objective: To analyze the results of an intra-arterially delivered combination chemotherapy in a group of patients with regionally advanced hepatocellular carcinoma (HCC). Methods: 26 patients with proven locally advanced HCC treated with hepatic artery infusion of cisplatin (20 mg/m², days 1–5) and etoposide (75 mg/m², days 1–5) every 4 weeks were retrospectively studied. Results: In an intention-to-treat analysis, overall and complete response rates were 38 and 7%, respectively. Median duration of response was 5 months. Median survival time was 10 months and survival rates at 6, 12 and 24 months were 53, 33 and 24%, respectively. Survival was significantly longer for responders than for non-responders (median: 13 and 3 months, respectively). There were 4 treatment-related deaths among cirrhotics. Conclusions: Intra-arterial chemotherapy using cisplatin and etoposide seems to have some anti-tumor effect against advanced HCC, although a high rate of life- threatening complications precludes the indication of this regimen at least for patients with non-compensated cirrhosis.

The incidental finding of an enlarged mastoid foramen on the right posterior mastoid region of temporal bone is reported, together with a discussion of its clinical significance. A 67-year-old female underwent the pre-implant assessment of a maxillary left edentulous region. A cone-beam computed tomographic (CBCT) image was acquired and referred for consultation. Axial CBCT slices revealed a unilateral, well-defined, noncorticated, low-attenuation, transosseous defect posterior to the mastoid air cells in the right temporal bone. The borders of the osseous defect were smooth and continuous. No other radiographic signs suggestive of erosion or sclerosis were noted in the vicinity. The density within the defect was homogenous and consistent with a foramen and/or soft tissue. The patient's history and physical examination revealed no significant medical issues, and she was referred to a neuroradiologist for a second opinion. The diagnosis of an enlarged mastoid foramen was made and the patient was reassured.
