Objective: Inventory of patients with immunodeficiency in the Netherlands.
Design: Retrospective over the period 1970-1983.
Setting: Dutch Working Group on Immunodeficiency, University Children's Hospital, 'Het Wilhelmina Kinderziekenhuis', Utrecht.
Method: A questionnaire with specific information on immunodeficient patients was completed by clinical members of the Working Group i.e. paediatricians and internists. Diagnosis of the immunodeficiency was according to WHO recommendations.
Results: The data of 336 patients could be included and analysed. Defects in humoral immunity were the most common (62.9%), followed by combined defects (18.75%), T cell defects (7.4%), phagocytic disorders (6.8%) and complement component deficiencies (2.7%). Sixty-two patients (15.5%) died, notably those with combined T and B cell defects, selective T cell defects and those with immunodeficiency based on DNA repair defects. Autoimmunity was relatively frequent in immunodeficiency (7.7%) as was cancer (2.7%).
Conclusion: Results were similar to those of other European countries.

Combined Klippel-Feil syndrome, Sprengel deformity, and diffuse large B-cell lymphoma: A rare case report.

Klippel-Feil syndrome (KFS) is a rare congenital disorder characterized by the fusion of cervical vertebrae, with a clinical presentation that can vary widely due to genetic and phenotypic diversity. While KFS can occur as an isolated anomaly, it is often associated with other congenital conditions, such as Sprengel deformity, which may present with or without an omovertebral bone, complicating diagnosis and management. This particular case also involves diffuse large B-cell lymphoma (DLBCL), the most common subtype of non-Hodgkin lymphoma.

Alzheimer's disease (AD) is the most common neurodegenerative disorder, accounting for approximately 70% of dementia cases worldwide. Patients gradually exhibit cognitive decline, such as memory loss, aphasia, and changes in personality and behavior. Research has shown that mitochondrial dysfunction plays a critical role in the onset and progression of AD.

Biodegradable temporizing matrix (BTM) is a synthetic biodegradable dermal matrix that helps develop a non-skin graft amenable wound bed (eg, over tendon or bone) into a graftable wound bed, by acting as an inert scaffold for angiogenesis and formation of granulation tissue. There is currently a paucity of evidence to encourage its use in scalp defects following skin malignancy excision. This retrospective analysis aimed to evaluate the utility of BTM in this patient subset.

Mitochondria and lysosomes are critical for neuronal homeostasis, as highlighted by their dysfunction in various neurological diseases. Recent studies have identified dynamic membrane contact sites between mitochondria and lysosomes, independent of mitophagy and the lysosomal degradation of mitochondrial-derived vesicles (MDVs), allowing bidirectional crosstalk between these cell compartments, the dynamic regulation of organelle networks, and substance exchanges. Emerging evidence suggests that abnormalities in mitochondria-lysosome contact sites (MLCSs) contribute to neurological diseases, including Parkinson's disease, Charcot-Marie-Tooth (CMT) disease, lysosomal storage diseases, and epilepsy.

Introduction: This study utilized a injectable curcumin (Cur)-infused calcium phosphate silicate cement (CPSC) for addressing defects caused by bone cancer, and evaluated its promoting bone regeneration and exerting cytotoxic effects on osteosarcoma cells.
Methods: The material's physicochemical properties, biocompatibility with osteoblasts, and cytotoxicity toward osteosarcoma cells were rigorously analyzed.
Results: The findings demonstrate that CPSC-Cur signicantly prolongs the setting time, which can be optimized by adding silanized cellulose nanober (CNF-SH) to achieve a balance between workability and mechanical strength.
