Introduction: An unusual case of a 19 year old female, presenting with fever, pallor and hepatosplenomegaly for one month. She had microcytic anemia on peripheral smear examination but her bone marrow aspiration & biopsy revealed a hypercelluar marrow with megaloblastic erythroid hyperplasia. Resolution of fever within 48 hours of Vitamin B12 supplementation, initiated in view of the megaloblastic bone marrow picture & low serumVitamin B12 level, suggests a causal association. Conclusion: Vitamin B12 deficiency seems to be an unusual cause of PUO (Pyrexia of unkown origin) which should be ruled out in every case of PUO.

This article addresses a new method for classification of white blood cells (WBCs) using image processing techniques and machine learning methods. The proposed method consists of three steps: detecting the nucleus and cytoplasm, extracting features, and classification. At first, a new algorithm is designed to segment the nucleus. For the cytoplasm to be detected, only a part of it which is located inside the convex hull of the nucleus is involved in the process. This attitude helps us overcome the difficulties of segmenting the cytoplasm. In the second phase, three shape and four novel color features are devised and extracted. Finally, by using an SVM model, the WBCs are classified. The segmentation algorithm can detect the nucleus with a dice similarity coefficient of 0.9675. The proposed method can categorize WBCs in Raabin-WBC, LISC, and BCCD datasets with accuracies of 94.47 %, 92.21 %, and 94.20 %, respectively. It is worth mentioning that the hyperparameters of the classifier are fixed only with Raabin-WBC dataset, and these parameters are not readjusted for LISC and BCCD datasets. The obtained results demonstrate that the proposed method is robust, fast, and accurate.

Background: Malaria, despite intensive efforts to control, remains a leading cause of morbidity and mortality in humans. India contributes to 61 per cent of malaria cases and 41 per cent of malaria deaths in SEAR countries. The objective of the present study was to find out an incidence of mortality due to malaria with typical and atypical presentation.Methods: The present was conducted over a period of three years. During the study period 630 patients with clinical suspicion of malaria were tested for malaria using peripheral smear, QBC and RDT.Results: The mortality rate in this study group 161 (25.55%) out of which maximum mortality observed in patients with falciparum malaria either singly or with mixed infestation. There is no significant correlation between the typical and atypical presentations in the different age groups with mortality.Conclusions: For timely diagnosis and treatment a high index of suspicion for the disease should be maintained by treating physicians, especially in endemic areas. They should be aware of the varied manifestations to minimize the mortality due to malaria.

Background: Often, the first test used to diagnose anemia is a complete blood count (CBC). It determines the number, size, volume, and hemoglobin content of red blood cells. Peripheral smear is done for typing of anaemia. Such evaluation is necessary for proper treatment.Methods: A retrospective study was done in 300 anaemic patients at Shakuntala pathology laboratory, Nagpur. Patients were randomly selected including males and females. CBC and peripheral smear were analyzed.Results: Out of total 300 patients evaluated, the prevalence of anaemia was quite significant in females 225 (75%) than males 75 (25%). 66 females (22%) had mild anemia while 129 females (43%) had moderate anemia and 30 females (10%) had severe anaemia 36 males (12%) had mild anaemia, 30 males (10%) had moderate anaemia while 9 males (3%) had severe anaemia. In morphology of red blood cells, normocytic normochromic anaemia was seen in 132 (44%) females and in 45 (15%) of males. Microcytic hypochromic anaemia was seen in 90 (30%) females and 27 (9%) males. Macrocytic anaemia was seen in 3 (1%) females and 3 (1%) males.Conclusions: Prevalence of anaemia is quite high in females than males. Also, the severity of anaemia is more in females than males. So, heath programmes should be directed more towards females since adolescent age.

Marrow Fibrosis

Objectives: Primary myelofibrosis is rare in pediatrics, often manifesting as persistent idiopathic thrombocytosis.Transitions from pediatric to adult medical care can be complicated by workup requiring invasive procedures. J.M., an 18-year-old healthy male, presented for excessive gingival bleeding after wisdom tooth extraction. Workup revealed persistent thrombocytosis to 1,165K, prompting a referral to hematology-oncology. A peripheral smear was notable for many platelets but normal RBC morphology. He had splenomegaly on abdominal ultrasound and a decreased von-Willebrand's activity to antigen ratio, suggesting acquired vWD. A bone marrow biopsy was advised; however, J.M. became lost to follow up for over 9 months owing to self-reported anxiety about the procedure. He remained asymptomatic in this interim until he re-presented to clinic for easy bruising, with no other evidence of bleeding at the time. The biopsy was pursued, revealing hypercellular marrow for age with left shifted granulocytic and erythroid maturation, abnormal megakaryocytes, and 3% blasts. This was consistent with primary early myelofibrosis (PMF), positive for MF-1, CALR, and TP53 mutations and negative for JAK2 and BCR-ABL. He was transitioned to adult hematology, maintained on baby aspirin, and referred for potential allogeneic hematopoietic stem cell transplant (HSCT). PMF is characterized by marrow fibrosis due to secretion of fibroblast growth factor by clonally proliferative megakaryocytes. It is a disease of adulthood, with 67 years being the median age at diagnosis. Only 100 cases have been reported in children, most of which are secondary to AML, ALL or other malignancies.1 Most patients present with complications of extramedullary hematopoiesis or bleeding.2 Diagnosis is suggested by a leukoerythroblastic picture on peripheral smear and confirmed with a bone marrow biopsy "dry tap" revealing marrow fibrosis.3 Prognosis in pediatric PMF is difficult to predict but outcomes tend to be worse;4 TP53 mutation is rare and based on limited adult studies may portend a poorer prognosis.5 Our young patient with this rare mutation was therefore referred for HSCT evaluation. Further complicating this case was J.M.'s anxiety, which delayed definitive diagnosis by biopsy. He only agreed to it when, at the med-peds clinic, the concept of local pain management was discussed. Anticipation of upcoming procedures by primary care physicians and close follow-up is especially important for patients transitioning from pediatric to adult providers.

A 49-year-old African American woman was admitted to our hospital with abdominal pain, nausea, vomiting, lethargy, and confusion. She was receiving ciprofloxacin for a urinary-tract infection prior to admission. Laboratory examination revealed anemia, thrombocytopenia, elevated lactate dehydrogenase, and serum creatinine. Peripheral smear showed numerous schistocytes, and the patient was diagnosed with thrombotic thrombocytopenic purpura (TTP). Ciprofloxacin was identified as the offending agent. The patient received treatment with steroids and plasmapheresis, which led to rapid clinical recovery. This is the first case to our knowledge of successfully treated ciprofloxacin-induced TTP; previously reported cases had fulminant outcomes. Quinolones are an important part of the antibiotic armamentarium, and this case can raise awareness of the association between quinolones and TTP. A high index of suspicion for detection and early and aggressive management are vitally important for a successful outcome.

Abstract Tumor cells circulate in the blood, but it is unusual to find cancer cells on a routine peripheral smear. The term carcinocythemia is used to describe this phenomenon. Four patients have been reported previously with small cell lung cancer and carcinocythemia. A fifth case is described in this article. These patients presented with advanced disease and had generalized lymphadenopathy and liver involvement; 3 had splenic metastases. All of these patients experienced rapid clinical deterioration. Death occurred 3 days to 2 weeks from the time carcinocythemia was detected. The presence of small cell carcinocythemia can be one of the manifestations of end-stage disease and is associated with an extremely poor prognosis.
