THE COMPLETE BLOOD COUNT (CBC) is one of the more common laboratory tests ordered during the neonatal period. The CBC may be obtained to evaluate for anemia, infection, and thrombocytopenia.1 The test offers a wealth of clinical information about the hematopoietic system, including erythrocyte, leukocyte, and thrombocyte values. Establishing normal neonatal ranges has been difficult because blood has not been drawn on healthy neonates of similar ages.2 Reference ranges that consist of the 5th to 95th percentile compiled from various studies have been used to approximate normal neonatal values.3 A variety of factors such as sample site, timing of the sample, gestational age, and the neonate’s degree of health can affect the CBC.1 Therefore, the astute practitioner must be able to recognize the clues and nuances of the CBC to guide the diagnostic assessment.4

Aim: To establish the reference values of hematological parameters in blood donors of all the four provinces of Pakistan as a general population. Methods: This was a multicenter cross-sectional study conducted from Jan 2017-Oct 2017 in the blood bank and the Dept. of Haematology, The CH&ICH, Lahore, Fatimid Foundation, Karachi, Bolan medical college, Quetta, Armed Forces Institute of Transfusion, Rawalpindi & Ayub medical college, Abbottabad, KPK. Blood samples of 1060 male and female blood donors were collected from the blood banks of all the centers mentioned above. CBC and differential were performed using an automated hematology analyzer in the respective departments. Results: The mean and 95% reference values (2.5th-97.5th) for males WBC 7.752+4.506×109 cells/L, RBC 4.958 +1.331, HB 14.258 +3.423 g/dl, HCT 41.967 +16.345, MCV 84.584 +15.933, PLT 219.485 +197.331, LYM 3.346 +10.112, NEUT 6.843+23.557, MONO 0.811 +3.601, EO 0.327 +0.995. For females WBC 7.174+3.037, RBC4.567 +1.086, HB 12.972 +2.752, HCT39.647 +48.186, PLT 264.07+175.079, LYM 2.537+5.005, NEUT 4.769+11.314, MONO 0.460 +0.909, EO 0.188+0.39 Conclusion: The hematological profile of the population in all four provinces of Pakistan differed from the reports of other countries and the standard reference ranges described in the textbook. So, our own hematological parameters must be followed. More studies must be carried out on other age groups and even on adults to strengthen our results.

Objective. To determine primary-care pediatricians' management of febrile infants and compare them with published practice guidelines. Design. Case scenarios were sent to 194 primary-care pediatricians in Utah, describing three febrile infants, ages 21 days, 60 days, and 20 months, corresponding to the three age groups: 0 to 28 days; 29 to 90 days, and 91 days to 36 months for which the guidelines suggest different strategies. Results. Ninety-four pediatricians responded (response rate, 48%). Compliance with the guidelines was 39% for the 21 day old, 9.6% for the 60 day old, and 75% for the 20 month old. No respondent followed the guidelines for all three infants. Performance of tests to determine if an infant was low risk varied from 3%, for a stool white cell examination in a febrile 2 month old with diarrhea, to 75% for a complete blood count in a 20 month old with a temperature of 40°C. Compliance did not differ between private and academic practitioners. Those in practice less than 5 years (n = 22) were more likely than those with more experience to follow the guidelines for the 21 day old but not the other two infants. Conclusion. Primary-care pediatricians in Utah manage febrile infants with fewer laboratory tests and less hospitalization than recent practice guidelines developed by an expert panel of academic specialists suggest.

The reference values of laboratory tests are affected by factors such as instruments and methods of tests, which are always beingdeveloped. For these reasons, each laboratory is recommended to determine their own reference values. To determine the reference valuesof complete blood count in healthy adult people, and compare them to the reference values which is taken from the references. A crosssectional study was conducted on 200 healthy adult people, aged 18-60 years, selected during blood donation. The eight haematologicalparameters were estimated using Sysmex Xt-1800i at Dr.Wahidin Sudirohusodo Hospital. The data were analyzed statistically by SPSS11.5 programs. The reference values of leukocyte, erythrocyte, haemoglobin, hematocrit, MCV, MCH, MCHC and platelet were: 4400 to10000 /µL; %:4.2–6.2 × 106/µL; &:3.8–5.5 × 106/µL; %:12.5–17.3 g/dL; &:11.8–15.4 g/dL; %:38.1–50.4 %; &:31.1–49.7 %; 80,1to 94,3 fL, 25,9–31,9 pg, 31,4–35,2 g/dL, and %:171.2–405.1 × 103/µL; &:191.8–441.5 × 103/µL, respectively. Significant differenceswere observed in the MCH and platelet values (p< 0,005). The values found in this study were similar to the reference value commonlyused in our laboratory, except for the MCH value which was lower and the platelet value which was higher..

Acute appendicitis is one of the most common causes of acute abdominal diseases seen between the ages of 10 and 19, mostly seen in males. The lifetime risk of developing acute appendicitis is 8.6% for males and 6.7% for females. We aimed to investigate the efficacy of the complete blood count parameters, C-reactive protein, and Lymphocyte-C-reactive Protein Ratio laboratory tests in the diagnosis of acute appendicitis, as well as their relationship with appendix diameter. We retrospectively examined all patients who underwent appendectomy between 1 January 2012 and 30 June 2019 in the General Surgery Clinic of Gaziosmanpasa University Faculty of Medicine. Laboratory tests, imaging findings, age, and gender were recorded. Lymphoid hyperplasia is considered as normal appendix—in other words, as negative appendicitis. The distribution of Lymphoid hyperplasia and appendicitis rates were statistically different in the groups formed according to appendix diameter (≤6 and >6 mm) (p < 0.001). We found a significant correlation between appendix diameter and WBC (White blood count), Lymphocyte, Neutrophil, RDW(Red blood cell distribution width), NLR(Neutrophil to lymphocyte ratio), and PLT/L (Platelet to lymphocyte ratio), MPV (Mean platelet volume) and RDW were significantly different in patients with an appendix diameter of ≤6 mm (p = 0.007, p = 0.006, respectively). WBC, Neutrophil, PDW, and NLR values were significantly different between appendicitis and hyperplasia groups in patients with an appendix diameter of >6 mm. The sensitivity of the NLR score (cutoff = 2.6057) in the diagnosis of appendicitis was 86.1% and selectivity was 50% in these patients. Complete blood count parameters evaluation with the clinical findings revealed that NLR is an important parameter that may help the diagnosis of acute appendicitis with an appendix diameter of >6 mm. In patients whose pathological results indicated acute appendicitis but who had a diameter of ≤6 mm, we found an elevated MPV and low RDW values.

The PDF was correct.Introduction: Reference hematological values in newborns are informative in evaluation of newborns to determine state of health or disease. For a given population, reference values may differ in accordance with various factors such as age, sex, race, diet, drug intake, altitude, socio-economic status and also the method employed for determination of the values. The aim of this study was to establish reference ranges of complete blood count using umbilical cord blood of normal, healthy, full term neonates born in Manipal Teaching Hospital (MTH), Pokhara, Nepal.Material and Method: The study was conducted in 210 full term, healthy newborns delivered in MTH between Jan 2014 to Feb 2015. Cord blood was collected and a complete blood count was obtained using an automated hematology analyzer.Result: Mean hemoglobin was 15.24 ± 1.96 gm/dl and mean red blood cell count was 4.30 ± 0.63 (range 3.05 – 6.36) X 1012/L. Mean white blood cell count was 14.93 ± 4.44 (range 6.10 ± 31.7) X 109/L and platelet count was 226.88 ± 61.28 (range 105 ± 392) X 109/L. There was no significant difference found in hemoglobin, red cell, white cell and platelet counts between males and females in this study.Conclusion: The values obtained from our study provide ranges for some hematological values in healthy newborns of Pokhara Nepal. However, the hematological reference values for Nepalese cord blood needs to be confirmed by larger numbers of samples from different centers of Nepal.J Nepal Paediatr Soc 2016;36(2):160-164.

Objective This study was aimed to establish local reference values for hematological indices and hemoglobin (Hb) fractions in umbilical cord blood (UCB) for the northern population of Tunisia. Study Design Our study included full-term newborns by vaginal deliveries. Hematological parameters were collected using an automated blood cell counter. The amounts of Hb fractions were measured by capillary electrophoresis of Hb. Statistical analysis was performed using R software. Results A total of 328 cord blood samples were analyzed. Among them, 154 (male: 44.8%, female: 55.2%) were used to establish reference values. The normal reference values of complete blood count (CBC) and Hb fractions were calculated. Mean neonatal Hb was 14.75 ± 2.26 g/dL. Gestational age affects the expression of CBC values as red blood cell (RBC), Hb, hematocrit (Hct), mean corpuscular volume (MCV), white blood cell (WBC), and the Hb profile. Umbilical blood hemogram parameters and Hb profile are affected by the environment; higher in newborns from urban regions but not affected by gender ratio. Conclusion Reference ranges of normal CBC indices and Hb fractions have been successfully established in Tunisian neonates' UCB. Our data suggest reference values that could be useful for neonatal patients' laboratory results and clinical interpretation. Key Points

A 15-month-old intact female Pitbull was referred because of recurrent, episodic, self-limiting, excitement-induced bleeding from nontraumatised skin. No abnormalities were detected upon physical examination. Subsequently, the dog went for a walk under the direct supervision of one of the authors, became overexcited and, after approximately five minutes, bloody liquid, with a patchy distribution, appeared along the hair shafts of the face and neck. The affected skin was congested, partially blanching on diascopy and bloody liquid was oozing from the follicular openings. Urticaria, dermographism and hypertension were excluded, the complete blood count and coagulation profile were within the reference ranges and an analysis of the bloody exudate confirmed its blood components. The cutaneous bleeding of the dog followed a self-limited course, with no episodes during the last two years. Clinical and laboratory findings and the long-term evolution of this dog bear striking similarities to haematidrosis, a rare human disease of multifactorial aetiology and equivocal pathogenesis.

Aim: This study assesses the effects of HAART on complete blood count parameters among HIV infected participants. Study Design: Case control study. Place and Methods: This study was conducted in Tamale, Ghana from August, 2016 to December, 2017. Methodology: A total of 300 HIV infected participants with ages ranging from 19–79 years, administered with HAART for at least 6 months were recruited. Pre-HAART administration (baseline) demographic and clinical information, with initial full blood count results were retrieved from the medical records of the participants. Post HAART administration blood sample (5mLs) was taken from each participant into an EDTA vacutainer tube and complete blood count (CBC) performed using URIT 5250 haematology analyser. Participants transfused with blood over the last 4 months were excluded from the study. Results: The study recorded significant decreases in WBC and Neutrophil (%) post HAART administration. Lymphocyte (%), Haemoglobin, Haematocrit, MCV, MCHC, RDW-SD were all significantly higher post HAART administration. Total Platelets count, MPV, PDW-SD, PCT and P-LCR were significantly lower post-HAART administration. A comparison of the effects of EFV and NVP administered with AZT/3TC backbone yielded the following results. The NVP group recorded a significantly higher HCT compared with the EFV group (p-0.0073). A significantly higher mean PCT, MPV, P-LCR, PLCC, PDW-SD were recorded in the EFV group compared to the NVP group respectively. Conclusion: The administration of HAART is associated with significant improvements in erythroid and lymphoid lineages, reduce anaemia, improves immunity and general patient well-being. NVP improve erythroid cell indices while EFV ameliorate platelet indices. HAART regimen should be chosen based on the pre-HAART laboratory tests conducted on the individual.
