The risk of hemorrhage in stereotactic biopsy for brain tumors.

Conclusion : Stereotactic biopsy is a less invasive procedure for obtaining samples of brain tumors for diagnosis. The bleeding of the tissue-resection cavity that includes asymptomatic hemorrhage occurs at a constant rate. It is important to reduce the symptomatic bleeding associated with stereotactic biopsy. J. Med. Invest. 66 : 314-318, August, 2019. PMID: 31656296 [PubMed - in process]

Conclusion: We report a 33.9% positive yield, with 65.8% of patients undergoing further workup as a result of CE and 12.7% requiring therapeutic intervention. We conclude that CE plays an important role in the investigation of IDA and occult gastrointestinal bleeding and has important implications on further management.

We report a case of the pathologically evaluated antitumor effect of pembrolizumab, a programmed death-1 immune checkpoint inhibitor antibody, in G-CSF-producing bladder cancer. A 53-year-old male patient underwent 4 courses chemotherapy with a combination of gemcitabine and carboplatin before a radical cystectomy with ileal neobladder. Four months after the surgery, local recurrence was detected in the pelvis and therefore pembrolizumab was used. One week after its administration, the patient showed increased mucus in his urine. A computed tomography scan and cystoscopy revealed a fistula between the ileum and the neoblad...

Conclusions: M1 disease at PC diagnosis was associated with worse survival after CRPC onset versus M0. Higher Gleason score at diagnosis was associated with higher mortality after CRPC onset in M0 patients at diagnosis. PMID: 32266854 [PubMed - as supplied by publisher]

CONCLUSIONS: Large ranges of FOV and PKA were found for a given indication, demonstrating the importance of establishing DRLs as well as FOV recommendations in view of optimizing the present practice. For now, only DRLs for dental and maxillofacial could be defined; because of a lack of ENT data, no DRL values for ENT practices could be derived from this survey.

Conclusions: This is an institution-based, detailed, and descriptive epidemiological study of patients with primary CNS tumors in Saudi Arabia. In contrast to other regional and international studies, the medulloblastomas in our institution are more frequent than pilocytic astrocytomas. Limitations to our study included the referral bias and histology-based methodology. PMID: 32256589 [PubMed]

Background: Reduced bone mineral mass by dual x-ray absorptiometry is reported in children living with HIV (CLWH), but few studies of bone microarchitecture, particularly in sub-Saharan Africa, have been conducted. Here, we compare bone architecture and strength in black South African CLWH and uninfected control children by peripheral quantitative computed tomography (pQCT). Setting and Methods: One hundred seventy-two CLWH on antiretroviral therapy (ART) and 98 controls in the CHANGES Bone Study in Johannesburg, South Africa received pQCT scans of the radius and tibia. Measurements included trabecular and cortical vo...

AbstractPatients with primary or metastatic brain tumors are at increased risk of developing venous thromboses. However, the potential benefit of therapeutic anticoagulation in these patients must be weighed against the deadly complication of intracranial hemorrhage. In this review, we summarize available evidence and recent studies of intracranial bleeding risks in primary and metastatic tumors and the impact of therapeutic anticoagulation. We find that for the majority of primary and treated metastatic brain tumors, the risk of spontaneous bleeding is acceptable and not further increased by careful therapeutic anticoagul...
