Abstract PURPOSE: Automated hematology analyzers yield a complete hematological profile including a complete blood count and a differential white blood cell count. The differential count is based on analyses of three parameters, namely, volume, conductance, and scatter (VCS). We aimed to evaluate the VCS parameters, histograms, and scatterplots of neoplastic and nonneoplastic lymphocytes. MATERIAL AND METHODS: Patients were grouped into four categories, namely, acute lymphoblastic leukemia (ALL), chronic systemic disorders, chronic lymphocytic leukemia (CLL), and acute viral disease. Lymphocytes from all four groups were compared with lymphocytes from normal participants. RESULTS AND CONCLUSIONS: The histogram for acute viral disease showed a trough at T1, which was slightly obliterated, and the F1 curve mildly extended to the right. The T1 for ALL was replaced with a peak at >40% of the preset limit. The F1 peak was shifted to left for CLL. The scatterplot for viral disease showed lymphocytes extending to the variant lymphocyte window. The lymphocytes of ALL extended to the blast window, with both increase in volume and mild increase in scatter. The lymphocytes in CLL were smaller and located below the normal lymphocyte region. Mean lymphocyte volume was significantly increased in ALL and was significantly decreased in CLL. Mean lymphocyte conductance was significantly increased in CLL and significantly decreased in both acute viral disease and ALL. Mean lymphocyte scatter was significantly decreased in acute viral disease and significantly increased in ALL.

Leukemia Cutis

Chronic lymphocytic leukemia (CLL) is a malignant, low-grade, monoclonal disorder characterized by the accumulation of lymphocytes with variable clinical features. Cutaneous manifestations or leukemia cutis are non-specific, uncommon presentations of CLL and can present in many different ways. In this case report, we discuss a 76-year-old male who presented with skin lesions of the lower limbs and severe itching. Due to the lack of response to the treatment with topical corticosteroids, initial tests were carried out. Complete blood count results indicated lymphocytosis. Eventually Ultimately, the skin lesions led to the diagnosis of CLL. The patient was treated with bendamustine-rituximab (BR). After receiving the treatment, all cutaneous manifestations and generalized itching disappeared. This case highlights the importance of comparing similar cases of CLL presented with dermatological conditions in order to to understand proper management and practice.

Anemia Of Inflammation

Sialolithiasis is a chronic disease in which a sialolith (salivary stone) causes recurrent inflammation of the affected salivary gland. Anemia of inflammation is a well-described pathology in which a chronic inflammatory disease leads to a reduction in the red blood cell count, hemoglobin and hematocrit values. In this retrospective cohort study, we aim to find whether removal of the sialolith and alleviation of the inflammation affect the complete blood count results. We examined data regarding forty-nine patients who underwent surgery for the removal of a submandibular gland sialolith using the duct-stretching technique. Complete blood counts two years before and after the surgical procedure were collected. The average pre-procedure and post-procedure values were calculated for each patient to establish the average blood profile. The pre- and post-procedure values were compared to evaluate the effect of the surgical treatment on the blood profile. We found that the average blood count values for patients with sialolithiasis were towards the lower end of the normal range. Post-surgery, a significant increase in hematocrit, hemoglobin and red blood cell count was observed, which was more pronounced in the older age group and in patients with co-morbidities. We conclude that sialolith removal surgery is associated with significant improvement in the complete blood count values, especially in the elderly and in patients and with co-morbidities. The speculated pathogenesis is relative anemia of inflammation.

150 febrile patients included children (50), adult (50) and neonates (50) from outpatient departments and inpatients of private clinics and hospitals. Patients presented with fever and chills for more than 1 day to 3 days, throat infection, ear infection and cold and fever and only fever as the principal symptoms. After clinical examination all the patients were prescribed for Complete Blood Count (CBC) with differential count(DC) and C-reactive protein(CRP) tests, and in children below 14 years anti-Streptolysin O(ASO) tests ( 75) were prescribed. Patients treated with antibiotics previously two weeks before the study period were not included. Qualitative and quantitative tests were performed on all patients’ samples included in the study depending on the need/prescription by the physician or paediatrician. CBC, neutrophil count and CRP have been very useful indicators and significant in the diagnosis and treatment as well as follow-up of the febrile condition of the patients specially in patients suffering with bacterial infections. Even in patients with Dengue and malaria it gives a fair idea if there were leucocytosis or leukopenia, neutrophilia or neutropenia, thrombocytosis or thrombocytopenia. CBC: Complete blood count, DC: Differential count; MP: malarial parasite, CRP: C-reactive protein, ASO: Anti-Streptolysin O.

Objectives Down syndrome (DS) is associated with multiple complications, including a high risk of leukemia and thyroid dysfunction. This clinical study aimed to examine the complete blood cell count in patients with DS without leukemia or transient abnormal myelopoiesis. We also aimed to evaluate the effect of thyroid dysfunction on hematological anomalies in DS. Methods We analyzed the peripheral blood cell count in 23 pediatric patients with DS with and without thyroid dysfunction and in 17 pediatric patients without DS with thyroid dysfunction. Results Patients with DS showed greater neutrophilia and lymphopenia than did patients with DS and hypothyroidism and patients with hypothyroidism. Surprisingly, patients with DS showed a significant degree of eosinopenia in the peripheral blood. Interestingly, hypothyroidism had an attenuating effect on different lineages in the complete blood count. However, these anomalies were specific for DS. Conclusions Our clinical findings support previous data on DS-associated changes in the complete blood count. Our study also shows novel alterations in the complete blood count in leukemia-free patients with DS in association with hypothyroidism. The attenuating effect of thyroid dysfunction on changes in different lineages in the context of DS is novel and deserves further analysis in larger studies.

ABSTRACT A 13 yr old male neutered Bengal cat was evaluated for a ventral cervical swelling, occasional vomiting, and decreased energy. Serum biochemistry, complete blood count, and physical examination were unremarkable apart from the cervical swelling. Serosanguinous fluid was drained from the cyst-like structure; however, the mass returned. Computed tomographic imaging revealed a large rounded-to-oval–shaped cystic structure in the region of the right thyroid gland with no obvious metastatic changes to the pulmonary parenchyma. The mass was surgically excised, and the tissues were histologically consistent with thyroid carcinoma. No evidence of recurrence or metastasis was present 6 mo postoperatively. Thyroid carcinomas are rarely reported in domestic cats; consequently, there is little research available on the topic. Until more research is made available, veterinarians may look to information available in canine literature to guide their treatment plans, but no definitive statements regarding therapy and ultimate prognosis can be made.

Context.— A novel automated slide-based approach to the complete blood count and white blood cell differential count is introduced. Objective.— To present proof of concept for an image-based approach to complete blood count, based on a new slide preparation technique. A preliminary data comparison with the current flow-based technology is shown. Design.— A prototype instrument uses a proprietary method and technology to deposit a precise volume of undiluted peripheral whole blood in a monolayer onto a glass microscope slide so that every cell can be distinguished, counted, and imaged. The slide is stained, and then multispectral image analysis is used to measure the complete blood count parameters. Images from a 600-cell white blood cell differential count, as well as 5000 red blood cells and a variable number of platelets, that are present in 600 high-power fields are made available for a technologist to view on a computer screen. An initial comparison of the basic complete blood count parameters was performed, comparing 1857 specimens on both the new instrument and a flow-based hematology analyzer. Results.— Excellent correlations were obtained between the prototype instrument and a flow-based system. The primary parameters of white blood cell, red blood cell, and platelet counts resulted in correlation coefficients (r) of 0.99, 0.99, and 0.98, respectively. Other indices included hemoglobin (r = 0.99), hematocrit (r = 0.99), mean cellular volume (r = 0.90), mean corpuscular hemoglobin (r = 0.97), and mean platelet volume (r = 0.87). For the automated white blood cell differential counts, r values were calculated for neutrophils (r = 0.98), lymphocytes (r = 0.97), monocytes (r = 0.76), eosinophils (r = 0.96), and basophils (r = 0.63). Conclusions.— Quantitative results for components of the complete blood count and automated white blood cell differential count can be developed by image analysis of a monolayer preparation of a known volume of peripheral blood.

Objective This study aimed to estimate the importance of complete blood count parameters for predicting the timing of birth in threatened preterm labour cases. Methods We performed a retrospective study of 92 patients who were diagnosed with threatened preterm labour (24–34 gestational weeks). The patients were divided into two groups according to the time of birth (group 1: delivered within the first week after diagnosis; group 2: delivered later than 1 week). We compared characteristics and complete blood count parameters between these two groups. Results There were no significant differences in maternal age, body mass index, gravida, parity, haemoglobin levels, and gestational weeks between the two groups. The mean cervical length was 24.24 ± 3.60 mm in group 1 and 30.70 ± 5.32 mm in group 2. There were significant differences in the neutrophil to lymphocyte ratio, white blood cell count, red cell distribution width (RDW), absolute lymphocyte cell count, and absolute neutrophil cell count between the two groups. Conclusion Maternal serum RDW, the neutrophil to lymphocyte ratio, white blood cell count, absolute lymphocyte cell count, and the absolute neutrophil cell count profile could guide clinicians in predicting the time of birth in threatened preterm labour cases.
