Object: Bone marrow transplantation has improved the prognosis of haematological malignancies, but patients are consequently at considerable risk of developing ocular complications, such as cataracts.
Material And Methods: A retrospective case study of 36 eyes (24 patients), with cataract extraction after the transplantation. Surgery was performed at a mean of 4.5 years after transplantation and the average age was 33 years at the time of surgery. The lens changes were all of the posterior subcapsular type. Surgery was indicated for symptoms of dazzling and glare; visual acuity was only moderately decreased (4/10, P6).
Results: Cataract surgery required specific measures such to "polish" the posterior lens capsule, since cataract changes were often very adherent. The surgery follow-up was uncomplicated with the exception of five eyes which had an inflammatory reaction (3 cyclitic membrans, 2 "pseudo-endophthalmitis") but which showed complete regression after treatement. The follow-up after surgery varied from 6 months to 4.5 years. Final visual outcome was improved. 82.5% achieved 8/10, and 96.8% achieved P2. Three YAG-laser capsulotomies were performed, mainly for posterior capsulofibrosis.
Comments: Cataract surgery after bone marrow transplantation appears to have a good prognosis. Posterior capsule "polishing", though difficult, is possible in most cases. In our study, secondary cataract appears to be less frequent, but, further long-term follow-up is needed to confirm this statement.

Influence of HLA-B Leader (-21M/T) Dimorphism With Bw4/Bw6 Epitopes on Graft Versus Host Disease After Allogenic Haematopoietic Stem Cell Transplantation in North Indians.

High degree of variability in human leukocyte antigens (HLAs) system restricts availability of histocompatible HLA-matched-related donors, thus increasing reliance on worldwide bone marrow registries network. Nevertheless, due to limited coverage/accessibility/affordability of some ethnicities in these registries, haploidentical haematopoietic stem cell transplantation (HSCT) emerged as an alternative option, though with allorecognition-mediated graft versus host disease (GvHD) (>40% cases). A dimorphism [-21 methionine (M) or threonine (T)] in HLA-B leader peptide (exon 1) which differentially influences its HLA-E binding, plausibly regulates natural killer cell functionality, affecting GvHD vulnerability and clinically in practice for donor selection.

Individuals diagnosed with Castleman disease (CD) and TAFRO syndrome (characterized by thrombocytopenia, anasarca, fever, bone marrow fibrosis, and organomegaly) displays a wide range of clinical symptoms, including varying patterns of lymph node enlargement, systemic inflammation, and impaired organ function. Some patients may present with both CD and TAFRO syndrome concurrently. A retrospective study conducted across multiple centers in Japan examined 321 cases to determine if the quantity and position of swollen lymph nodes could forecast the clinical progression and intensity of these conditions.

Hematopoietic stem cell transplantation (HSCT) is an established treatment for selected patients with inborn errors of metabolism. In this first report from the PDWP-SBTMO, we included 105 patients transplanted between 1988 and 2021 across six Brazilian HSCT centers. The most prevalent diseases were X-linked adrenoleukodystrophy (n = 61) and mucopolysaccharidosis (type I n = 20; type II n = 10), with a median age at HSCT of 8.

The objective of this study was to tailor an osteoinductive scaffold for alveolar bone regeneration and around immediately placed implants in extraction sockets of dogs. Tailored amorphous multiporous bioactive glass (TAMP -BG) was prepared and characterized for bioactivity and response of human alveolar bone marrow mesenchymal stem cells (hABMSCs). Extraction sockets of twenty-two male mongrel dogs received TAMP-BG in the right side around implant in the distal socket of the mandibular fourth premolar (P4), while the adjacent empty mesial socket of the same tooth was filled with the same graft.

Low back pain (LBP) is a commonly encountered medical disorder in Malaysia's primary care setting, though establishing a direct connection between LBP and the workplace environment in adults is challenging. This case presents a clinic nurse who developed LBP due to a prolapsed intervertebral disc and her clinical management from an Occupational Health Doctor perspective. Her occupational management involved a walk-through survey at an urban hospital, which identified bone marrow aspiration as her most physically demanding task.
