Tandem haematopoietic stem cell transplantation versus single cell transplant and BV maintenance in relapsed/refractory Hodgkin lymphoma: A matched cohort analysis from the LYSA

Autologous hematopoietic stem cell transplant (ASCT) is the standard curative treatment for patients with high-risk relapsed/refractory Hodgkin lymphoma (R/R HL). The AETHERA study showed survival gain with Brentuximab Vedotin (BV) maintenance after ASCT in BV-naive patients, which was recently confirmed in the retrospective AMAHRELIS cohort, including a majority of BV-exposed patients. However, this approach has not been compared to intensive tandem auto/auto or auto/allo transplant strategies, which were used before BV approval. Here, we matched BV maintenance (AMAHRELIS) and tandem SCT (HR2009) cohorts, and observed that BV maintenance was associated with better survival outcome in patients with HR R/R HL.

Bilateral Breast Cancer After Prophylactic Bilateral Pulmonary Irradiation

The purpose of this article is to report a new case of a probably radio-induced bilateral breast cancer occurred after prophylactic bilateral pulmonary irradiation in the treatment of osteosarcoma. A 42-year-old woman, treated at the age of 12 years for osteosarcoma at the right lower limb with chemotherapy (methotrexate, adriamycin and cisplatin) followed by non-conservative surgery and adjuvant radiotherapy. Eighteen years after, she developed her first breast cancer, and five years later, her second contralateral breast cancer. The patient was treated for her two non-metastatic cancers and is currently in complete remission. This publication adds to several previous publications the very probable effect of ionizing radiation in the occurrence of secondary cancers.

Patients with complicated Pott's disease: management in a rehabilitation department and functional prognosis

OBJECTIVE

The objective is to study the rehabilitation management and to assess autonomy in daily life activities as well as walking recovery in patients with complicated Pott's disease.

PATIENTS AND METHODS

Retrospective study in nine patients over a period of 8 years extending from 2000 to 2008, collated in the Department of Physical Medicine and Functional Rehabilitation, CHU Sahloul, Sousse, Tunisia.

RESULTS

The mean age of our patients was 43.8 years; sex ratio was 5/4. The spine involvement of tuberculosis was dorsal in seven cases, dorso-lumbar in one patient, and multiple (cervical, dorsal and lumbar) in one case. All patients were paraplegic with a neurological involvement of the bladder. They had prior antituberculosis chemotherapy for at least 8 months. Decompression surgery was performed in six cases. Two female patients presented disorders of spinal posture during treatment requiring surgical revision with osteosynthesis. All patients received additional rehabilitation care. Following a mean duration of hospitalisation in the Rehabilitation department of 47 days with twice-daily sessions of tailored physiotherapy, three patients remained in complete paraplegia, autonomous in wheel-chair and with vesical and sphincter incontinence. The measure of functional independence (MFI) was at admission/discharge 71/92.

CONCLUSION

Rehabilitation takes an important place in the medico-surgical management in Pott's disease, to limite or compensate the disabilities and handicap related to this pathology.

New support for the large-scale purification of proteins

We propose a new affinity sorbent, matrix-linked histidine, for the large-scale purification of proteins. A variety of proteins and certain peptides, each distinct from the other, were purified. Immunoglobulin G from human placenta was chosen for a detailed study concerning the effects of coupling, spacer-arm and other parameters. Multiple interactions such as charge-transfer and other ionic reactions have been suggested to be responsible for the interactions between proteins and ligand.
