Late diagnosis of leukocyte adhesion deficiency type II and Bombay blood type in a child: a rare case report.

Leukocyte adhesion deficiency type II (LAD II) is a rare, autosomal, recessive inherited immunodeficiency disease that induces frequent and recurrent infections, persistent leukocytosis, severe mental and growth retardation, and impaired wound healing. The Bombay blood group is a rare blood group phenotype that is characterised by the deficiency of H, A, and B antigens on the surface of red cells. LAD II and the Bombay blood group are always seen together, because both of them are associated with a global defect in the common pathway of fucose metabolism.

Targeted high-throughput sequencing for genetic diagnostics of hemophagocytic lymphohistiocytosis.

Background: Hemophagocytic lymphohistiocytosis (HLH) is a rapid-onset, potentially fatal hyperinflammatory syndrome. A prompt molecular diagnosis is crucial for appropriate clinical management. Here, we validated and prospectively evaluated a targeted high-throughput sequencing approach for HLH diagnostics.

herg1b expression as a potential specific marker in pediatric acute myeloid leukemia patients with HERG 897K/K genotype.

Human ether-a-go-go related gene (herg) encoding HERG K(+) channel has been demonstrated in many previous studies with its association to cell cycle progression and growth in tumor cells. The upregulated expression of HERG K+ channels was determined in different tumor types. Furthermore, not only full-length transcript herg1 but also a truncated isoform herg1b was shown to be expressed in cancer cells.

Infantile hemangiomas, complications and follow-up.

Objective: To study the risk factors for hemangioma-related complications, treatment indications and analyze the outcome of patients with infantile hemangioma.

Design: Retrospective.

Setting: University hospital.

How to manage an unresectable or recurrent sialoblastoma.

Only 2-5% of all salivary gland tumors occur in children. Sialoblastoma is an extremely rare salivary gland tumor diagnosed at birth or shortly thereafter with significant variability in histological range and clinical course, so that it may be difficult to predict the most appropriate therapy. In cases where surgical removal is not curative or technically feasible, chemotherapy may be attempted.

Allogeneic versus autologous versus peripheral stem cell transplantation in CR1 pediatric AML patients: a single center experience.

Background: Treatment of childhood acute myelocytic leukemia (AML) in first remission, is still evolving. Allogeneic bone marrow transplantation (BMT) in patients with a donor has been well established, but the role of autologous transplantation remains of interest, particularly in the light of some encouraging results in adults.

Procedure: Out of 81 pediatric patients with AML in first CR, 67 were biologically randomized for allogeneic (n = 31), autologous (n = 20), or peripheral stem cell transplant (n = 16) after completing consolidation treatment, with the remaining (n = 11) dropping out or receiving chemotherapy.

Neuroblastoma: an unusual presentation with bilateral ptosis.

Neuroblastoma, a common tumor of neural crest origin, demonstrates an extremely variable clinical presentation and behavior. Paraspinal tumors may occur anywhere along the spinal column where they may invade the intervertebral foramina and produce cord compression. Cervical involvement may produce Horner's syndrome.
