Sacral Resections for Primary Sacral Tumor - an Experience from a Tertiary Care Cancer Center in India.

Primary sacral tumors are uncommon and sacrectomy is a complex surgical procedure with substantial risk of morbidity. We conducted a retrospective study of patients who had undergone sacral resections for primary sacral tumors between 2010 and 2020. Ten sacral resections including five type 1 sacrectomy (S1 resected), four type 2 (S1 spared), and one type 3 (S3 spared) were performed during the above period.

Abbreviated protocol of plasma exchanges for patients with anti-factor H associated hemolytic uremic syndrome.

Background: Plasma exchanges (PEX) and immunosuppression are the cornerstone of management of anti-factor H (FH) antibody-associated atypical hemolytic uremic syndrome (aHUS), particularly if access to eculizumab is limited. The duration of therapy with PEX for anti-FH aHUS is empirical.

Methods: We compared the efficacy of abbreviated PEX protocol (10-12 sessions) in a prospective cohort of patients diagnosed with anti-FH aHUS (2020-2022), to standard PEX protocol (20-22 sessions) in a historical cohort (2016-2019; n = 65).

Unrepresented human leucocyte antigen alleles in single-antigen bead assays: A single-centre cohort study.

Human leucocyte antigen (HLA) alleles may generate antibodies that are undetectable by routine single-antigen beads (SABs) assays if their unique epitopes are unrepresented. We aimed to describe the prevalence and explore the potential impact of unrepresented HLA alleles in standard SAB kits in our cohort. All individuals who had undergone two-field HLA typing (HLA-A/B/C/DRB1/DQA1/-DQB1/-DPA1/-DPB1) from February 2021 to July 2023 were included.
