Background: Dysmegakaryocytopoiesis in patients with the plasma cell neoplasm (PCN) is rarely discussed in the literature. The puzzling phenomenon, which PCN patients maintaining normal platelet count even when the marrow is mostly replaced by plasma cells, is hardly explored.

Aim: This study was aimed to determine the frequency of dysmegakaryocytopoiesis in PCN and the relationships between bone marrow (BM) plasma cell percentage, plasma cell immunomarkers, the severity of dysmegakaryocytopoiesis, and peripheral blood platelet count in PCN.

Materials And Methods: We randomly selected 16 cases of PCN, among which 4 were with monoclonal gammopathy of undetermined significance and 12 were with plasma cell myeloma.

Results: OUR STUDY SHOWED THAT: (1) Dysmegakaryocytopoiesis was present in all the selected cases of PCN and its severity was not correlated with the percentage of the plasma cells in BM; (2) almost all patients maintained normal platelet count even when BM was mostly replaced by plasma cells; (3) immunomarkers of the neoplastic plasma cells were not associated with dysmegakaryocytopoiesis or maintaining of platelet count. The possible mechanisms behind dysmegakaryocytopoiesis and maintaining of platelet count were also discussed.

Conclusion: Despite the universal presence of dysmegakaryocytopoiesis in PCN, the platelet count is maintained at normal range.

Pediatric thrombocytopenia is frequently observed in critical care and oncology settings with an increased risk of bleeding and platelet transfusions. However, little is known about low platelets in childhood during seasonal influence. This study aimed to evaluate the frequency and severity of pediatric thrombocytopenia in the postflood period.

Thrombotic thrombocytopenic purpura (TTP) is an exceptionally rare complication during pregnancy and even rarer when it coincides with severe preeclampsia in the same index pregnancy. We report the case of a 36-year-old female who presented with confusion at 38 weeks of gestation. Although her signs and symptoms strongly suggested severe preeclampsia, she was expected to make a full recovery after an emergency C-section.

Background: The lactation period is a crucial period where the nutritional status and the mother's environment influence milk production, impacting organ differentiation, function, and structure in the baby's body.

Aim: The study aimed to determine the impact of providing lactating rats with quail egg supplements enriched with marine macroalgae on their physiological condition (blood cells, lipids, blood glucose, antioxidant activity, and prolactin hormone levels) and the growth of their offspring.

Methods: The study involved 25 lactating Sprague Dawley white rats aged 3 months old and weighing approximately 200 g divided into five treatment groups thus; T0 as the control, T1 with quail eggs enriched with commercial feed, T2 with quail eggs enriched with 3% of marine macroalgae, T3 with quail eggs enriched with 4% of marine macroalgae, and T4 with quail eggs enriched with 5% of marine macroalgae, which received one quail egg for 21 days.

Background: Age-related changes in physiological parameters are crucial in understanding the health and performance of working dogs, particularly those in demanding roles such as military and law enforcement. However, limited research exists on how aging affects the hematological and biochemical health of these dogs.

Aim: This study aims to characterize age-related variations in hematological and biochemical parameters in working Belgian Shepherd dogs to provide insights that could inform health management strategies for these animals.

Olanzapine, a second-generation antipsychotic widely used for schizophrenia, is primarily known for its efficacy in managing both positive and negative symptoms. While its metabolic side effects are well-documented, hematologic complications such as thrombocytopenia are rare and often underrecognized. A 30-year-old Middle Eastern male with a longstanding history of schizophrenia developed persistent thrombocytopenia after several years of olanzapine use, with platelet counts consistently below the normal range.
