Each time frame for counting is can also used to look for morphologic abnormalities of white several seconds and many thousands of cells are counted. The blood cells (when circulating abnormal white blood cell computer processes the counting data first by determining the population such as immature or atypical cells is suspected for agreement between the three counts. If acceptable criteria are diagnostic or monitoring reasons; this requires a high level of met, the counts are accepted and used to calculate the result. Principleand Procedure for Staining Thin Blood Film potassium cyanide that reacts with the hemoglobin to form Staining usually take place at a neutral pH. The voltage pulses produced by the white part of stain methylene blue stained the acidic part of the cell blood cells depend upon the size of the cell and its nuclear i. The to cell sizing, automated instruments may use any of three slide was diluted with buffered distilled water and allowed to other methods to distinguish between subpopulations.

The slide was allowed to air dry and examined under differential blood count provides a high level of accuracy and microscope using X100 objective lens [40, 41, 42]. Automation Techniques (Electronic Blood Cell method is not sensitive at identifying abnormal or immature Counting) Its Principle and Procedure cells and is not able to accurately identifying and classifying all types of white blood cells. To overcome this problem, most Electronic blood cell counting is based upon the principle of automated analyzers will flag samples with possible abnormal impedance (resistance to current flow). Some hematology white blood cell populations, indicating the need for analyzers combine both impedance counting with light peripheral smear examination to be examined by trained scattering to measure platelets. It remains a frontline diagnostic in agent) is added to destroy (hemolyze) the red blood cells. A unraveling mysteries behind cryptic symptoms and signs in small portion of the diluted fluid in each bath is allowed to primary and secondary haemopathies. An electrical current is produced in laboratory test or more advanced investigations may be each aperture by two electrodes, one on the inside and the required to confirm the diagnosis. The saline solution is responsible for conducting current between the electrodes [7, 43]. The cells move through the aperture one at a time, when a Recommendation cell enters the aperture, it displaces a volume of electrolyte Baseline parameters of complete blood cell count and equal to its size. The cell acts as an electrical resistor, and peripheral blood film is necessary especially for patients to be impedes the flow of current. This produces a voltage pulse, the placed on medication or chemotherapy, this will help in magnitude of which is proportional to the size of the cell. Instrument electronics are adjusted to discriminate voltage pulses produced by different cells, these adjustments are called thresholds.

Object discrimination allergy injections order cheapest periactin and periactin, which tests for higher cortical functions allergy medicine itchy eyes discount periactin 4mg online, can be done using coins allergy testing elizabethtown ky periactin 4 mg with visa, paper clips allergy forecast nyc mold discount 4mg periactin free shipping, or rubber bands allergy treatment therapy 4mg periactin sale. This sign can be elicited when the plantar surface of the foot is stimulated with a stiff object allergy testing requirements periactin 4 mg overnight delivery. This response can be normally seen in children up to 2 years of age or sometimes after a seizure. Another sign is clonus that can be tested by maintaining dorsiflexion of the foot. Sustained clonus is abnormal at all ages and signifies a lesion in the pyramidal tract or the cortical origin of the pyramidal tract. The neurological examination of the infant can be organized in the following fashion: 1) Posture and muscle tone, 2) Primitive reflexes, 3) Age invariable items. This can be divided in three ways: 1) resting posture, 2) passive tone, 3) active tone. Hypertonia in the extremities decreases after 3 months of age, with the upper extremities then the lower extremities. Passive tone is done by determining resistance of passive movements of the joints while the infant is awake and not crying. The scarf sign is where the arm is pulled across the chest and if the elbow passes the midline, then hypotonia is present. If hypotonia is present, then the head lags backward, then as the erect position is assumed, the head then drops forward. Primitive reflexes are usually present from the time of birth and represents spinal reflexes until the infant becomes older and higher cortical functions suppress them. Although there are many types of reflexes, it would be a good idea to do some of them and not necessarily all since they would not give more information than what was already done. The infant is suspended by holding the chest with both hands and lifting the patient in an upright position, with the legs dangling. If there is scissoring of the legs, then spasticity may be present making it suspicious that cerebral palsy may be present. Normally, the spine extends a little so that the eyes are looking just below the horizontal. This is done by having the head hyperextended, falling back about 3 centimeters in relation to the trunk. A normal response is seen when the infant opens his hands, extends and abducts the arms, and then brings them together, followed by a cry. A normal response is extension of the arm and leg on the side that the head is turned, and flexion of the arm and leg on the opposite side (similar to a fencing stance). Abnormal responses occur when this response is sustained or if it occurs Page 556 differently when the head is turned to the right or left. An abnormal response occurs when this response is absent before 2 to 3 months of age, persistence after this time, or asymmetry. The infant is suspended horizontally with the face down, and is brought quickly down toward the floor, making sure that the infant is firmly held. Reflex placing is seen when the dorsum of the foot is placed against the edge of the examination table. Reflex stepping is seen when the sole of the foot is placed on the table, and the infant appears to be walking. A black sheet paper is used and multiple strips of white tape (about 2 cm wide) are attached so that there are alternating strips of black and white. A straight piece of metal, such as from a dressing hanger, is used to pierce the top and bottom parts of the can and is thus the handle to rotate the drum. Examination of the skull, cranial nerves, strength, cerebellar function, sensory, and reflexes. Signifies that cortical vision is intact, in addition to showing the integrity of the frontal and parietal lobes, and visual fields. When the arms are lifted, a positive sign is when an arm is hyperpronated with the elbow flexed. It tests for strength of the upper extremities, and a positive sign signifies weakness. In newborns up to 2-1/2 years of age and sometimes in patients just after a febrile seizure. He was born at term by normal vaginal delivery without complications and his birth weight was 3300g. He is able to roll over from his stomach to his back but he is not able to sit or stand. His height and weight are both between the 25 50th percentiles and his head circumference is within 2 standard deviations of the mean. Intellectual, sensory, and/or behavioral problems may also exist although the primary abnormality must be a motor deficit. The majority of the cases are not caused by hypoxic ischemic incidents occurring perinatally as it was believed until recently. For example, in spastic diplegia, the lower extremities are more involved than the upper extremities. All the extremities and often trunk and oral motor function are also affected in spastic quadriplegia. Choreiform movements are asymmetric, uncoordinated, involuntary muscle contractions. It may not be apparent until about 12 to 18 months of age when a toddler starts to show athetoid or dystonic posturing on voluntary movements. For example, a child who has spastic quadriplegia may also have choreoathetoid movements. He or she may be difficult to feed, or require an excessive amount of time for feeding. A child may have failure to thrive or a poor rate of head growth due to a serious insult to the brain. The child may show a premature handedness preference during the first 18 months of life. By simple observation, you may be able to see poor head control, scissoring of the lower extremities, or flexor posturing of upper extremities. There are three patterns of movements: 1) Normal movements, 2) Abnormal movements which are never seen in normally developing children. E) Gross motor skills are usually affected but other developmental milestones should be also assessed to determine if delays are more global. These may include sensory impairments, seizures, cognitive impairment, orthopedic problems, impaired speech and language, feeding issues, dental problems, skin breakdown and respiratory infections. The treatment plans and programs must be individualized and modified over time as the child grows. There is also an increased incidence of sensorineural and conductive type hearing impairment. Seizures are most commonly seen among the children with spastic quadriplegia and hemiplegia. Although children with more severe motor involvement tend to have mental retardation more frequently, this is not always the case. Among children with normal intelligence, there is a higher incidence of learning disabilities. Because of the difficulties in motor control, assistance is needed to maintain good posture and alignment and good range of motion of the joints. Poor posture or positioning can result in scoliosis due to the unequal muscle tension. The interventions used to treat these conditions include physical therapy, orthopedic surgery, muscle tone management. The prognosis regarding ambulation is also dependent on the type and the severity of the motor dysfunction. With or without assistive devices, 80-90% of children with diplegia, 70% of children with dyskinesia and 50% of children with quadriplegia may achieve some degree of ambulation (1). For example, there is a good prognosis for attaining some ambulation if a child is able to sit independently by 24 months. It is important for the primary care physician to communicate with the therapists, specialists, and school personnel. The physician needs to advocate for the necessary services for the child and his/her family. Primary care physicians should be aware of the different problems and needs that the children experience as they get older and help them transition from the toddler to school age to adulthood as smoothly as possible. The goal for the treatment program is to maximize function and optimize development to help them participate in as many activities as possible in multiple social settings. Subtypes first a person has the choreoathetoid type, then the spastic type, and then becomes quadriplegic. Currently, most cases of cerebral palsy with a known etiology are thought to be a. True/False: Children with hemiplegia have a higher rate of ambulation than diplegia and quadriplegia References 1. Disorders of Development and Learning: A Practical Guide to Assessment and Management, 2nd edition. He has been in good health except for a high fever that developed today to about 103-104 degrees. About 20 minutes ago when the mother was checking up on her child, she noticed shaking of the arms and legs and his eyes had a blank stare. He has been ill with a high fever today and a slight cough and mild nasal congestion. His mother appears anxious and there appears to be good bonding between her and her child. It is the most common reason for convulsions in children less than 5 years of age, and they occur in 2 to 5% of all children, although it has been reported to be more frequent in Asian countries. It is thought that the rates in these areas are higher because some of the common infections of childhood may occur earlier in life when children are most susceptible to febrile seizures. Also, since more families sleep in the same room, this may make recognition better than in Western countries (1). The age at which febrile seizures most frequently occur is in the second year of life, and they occur slightly more commonly in boys than in girls. Simple febrile seizures are characterized by the following: duration less than 15 minutes, and generalized. Complex febrile seizures have the following features: duration greater than 15 minutes, multiple within 24 hours, and/or focal (2). The risk of recurrence after the first febrile seizure is about 33%, and about 9% will have three or more recurrences. The risks for recurrence are: occurrence of the first febrile seizure at a young age; family history of febrile seizures; short duration of fever before the seizure; relatively low fever at the time of the initial seizure; and possibly a family history of an afebrile seizure. It has been observed that the time of recurrence is usually within the first year of onset. Although complex febrile seizures are not usually associated with recurrent febrile seizures, they may be a risk factor for epilepsy later in life. Febrile seizures seem to run in families, but their mode of inheritance is unknown. The risk for other siblings developing febrile seizures is about 10-20%, but may be higher if the parents also have a history of febrile seizures themselves (2). The seizures are usually generalized and tonic-clonic, but other types may be present as well. Parents may describe stiffening, jerking, apnea, cyanosis and incontinence, usually followed by drowsiness (commonly called post-ictal for short). There may be variations to this such as staring without stiffness, jerking movements without prior stiffening, and localized stiffness or jerking. Simple, benign febrile seizures should be short, usually 1 to 2 minutes, but some may be longer (up to 15 minutes). Because of the short duration, medical attention usually occurs after the seizure has ended (2). Although the diagnosis of febrile seizure is likely in a 6 month to 5 year old with fever and a convulsion, one should consider other causes such as meningitis, encephalitis, Shigella gastroenteritis, medications/toxins (such as diphenhydramine, tricyclic antidepressants, amphetamines, and cocaine), hypoglycemia, electrolyte abnormalities (that could be due to dehydration), shaken baby syndrome, accidental head trauma, and epilepsy (2). Many of these other diseases can be ruled out by a good history, physical examination, and clinical appearance after the seizure has ended. How should these patients be managed in terms of diagnostic work-up and treatment The American Academy of Pediatrics attempted to answer this in two practice parameters on the evaluation and treatment of children with febrile seizures that were published in 1996 and 1999 (3,4). It should be kept in mind that these are guidelines only and that each case should be individualized according to the particular child, and the situation. One should remember that these guidelines are written for practitioners with a wide range of experience and training; therefore, the points mentioned here are meant to be conservative. Also these guidelines are written for children from 6 months to 5 years of age who had a simple febrile seizure and are neurologically normal. This is because antibiotics can mask the signs and symptoms of meningitis (partially treated meningitis). The clinical appearance of the child after the seizure has ended plays a very significant role, in that the playful, active child who appears normal, probably does not have meningitis. For example, electrolytes and glucose can be checked in a patient who is vomiting. A lumbar puncture should be strongly considered if the patient is young, if there are signs and symptoms of meningitis, if the patient is already on antibiotics, if there is no rapid improvement, or if the patient does not regain full consciousness (5).

It should be understood that these half-life values do not represent clearance of iron from the body allergy forecast irving tx purchase generic periactin on-line. Iron is not easily eliminated from the body and accumulation of iron can be toxic allergy symptoms under chin purchase periactin mastercard. Six different dialyzer membranes were investigated (polysulfone allergy shots bee stings discount 4 mg periactin mastercard, cuprophane allergy medicine vs cold medicine cheapest generic periactin uk, cellulose acetate allergy symptoms during period buy periactin no prescription, cellulose triacetate allergy forecast santa fe buy generic periactin from india, polymethylmethacrylate and polyacrylonitrile), including those considered high efficiency and high flux. Although reactions are usually evident within a few minutes, observe patients for a least one hour before administering the therapeutic dose. Fatal reactions have followed the test dose of iron dextran and have also occurred in situations where the test dose was tolerated. The factors that affect the risk for anaphylactic-type reactions to iron dextran products are not fully known but limited clinical data suggest the risk may be increased among patients with a history of drug allergy or multiple drug allergies. Additionally, concomitant use of angiotensin-converting enzyme inhibitor drugs may increase the risk for reactions to an iron dextran product. The extent of risk for anaphylactic-type reactions following exposure to any specific iron dextran product is unknown and may vary among the products. Iron dextran products differ in chemical characteristics and may differ in clinical effects. The adverse effects frequently are delayed (1-2 days) reactions typified by one or more of the following symptoms: arthralgia, backache, chills, dizziness, moderate to high fever, headache, malaise, myalgia, nausea, and vomiting. The onset is usually 24-48 hours after administration and symptoms generally subside within 3-4 days. The potential for a delayed reaction must be considered when estimating the risk/benefit of treatment. Carcinogenesis: A risk of carcinogenesis may attend the intramuscular injection of iron-carbohydrate complexes. Such complexes have been found under experimental conditions to produce sarcoma when large doses or small doses injected repeatedly at the same site were given to rats, mice, and rabbits, and possibly in hamsters. The long latent period between the injection of a potential carcinogen and the appearance of a tumor makes it impossible to measure accurately the risk in man. There have, however, been several reports in the literature describing tumors at the injection site in humans who had previously received intramuscular injections of iron-carbohydrate complexes. Such iron overload is particularly apt to occur in patients with hemoglobinopathies and other refractory anemias that might be erroneously diagnosed as iron deficiency anemias. Anaphylaxis and other hypersensitivity reactions have been reported after uneventful test doses as well as therapeutic doses of iron dextran injection. Reports in the literature from countries outside the United States (in particular, New Zealand) have suggested that the use of intramuscular iron dextran in neonates has been associated with an increased incidence of gram-negative sepsis, primarily due to E. The drug may cause falsely elevated values of serum bilirubin and falsely decreased values of serum calcium. Serum iron determinations (especially by colorimetric assays) may not be meaningful for 3 weeks following the administration of iron dextran. Examination of the bone marrow for iron stores may not be meaningful for prolonged periods following iron dextran therapy because residual iron dextran may remain in the reticuloendothelial cells. Bone scans involving 99m Tc-diphosphonate have been reported to show a dense, crescentic area of activity in the buttocks, following the contour of the iliac crest, 1 to 6 days after intramuscular injections of iron dextran. Bone scans with 99m Tc-labeled bone seeking agents, in the presence of high serum ferritin levels or following iron dextran infusions, have been reported to show reduction of bony uptake, marked renal activity, and excessive blood pool and soft tissue accumulation. Pregnancy: Pregnancy Category C: Iron dextran has been shown to be teratogenic and embryocidal in mice, rats, rabbits, dogs, and monkeys when given in doses of about 3 times the maximum human dose. No consistent adverse fetal effects were observed in mice, rats, rabbits, dogs and monkeys at doses of 50 mg iron/kg or less. Fetal and maternal toxicity has been reported in monkeys at a total intravenous dose of 90 mg iron/kg over a 14 day period. Similar effects were observed in mice and rats on administration of a single dose of 125 mg iron/kg. Fetal abnormalities in rats and dogs were observed at doses of 250 mg iron/kg and higher. Placental Transfer: Various animal studies and studies in pregnant humans have demonstrated inconclusive results with respect to the placental transfer of iron dextran as iron dextran. It appears that some iron does reach the fetus, but the form in which it crosses the placenta is not clear. Such reactions, which occur most often within the first several minutes of administration, have been generally characterized by sudden onset of respiratory difficulty and/or cardiovascular collapse. Because fatal anaphylactic reactions have been reported after administration of iron dextran injection, the drug should be given only when resuscitation techniques and treatment of anaphylactic and anaphylactoid shock are readily available. Neurologic: Convulsions, seizures, syncope, headache, weakness, unresponsiveness, paresthesia, febrile episodes, chills, dizziness, disorientation, numbness, unconsciousness. Miscellaneous: Febrile episodes, sweating, shivering, chills, malaise, altered taste. Dosages of iron dextran in excess of the requirements for restoration of hemoglobin and replenishment of iron stores may lead to hemosiderosis. Periodic monitoring of serum ferritin levels may be helpful in recognizing a deleterious progressive accumulation of iron resulting from impaired uptake of iron from the reticuloendothelial system in concurrent medical conditions such as chronic renal failure, Hodgkins disease, and rheumatoid arthritis. Iron Deficiency Anemia: Periodic hematologic determination (hemoglobin and hematocrit) is a simple and accurate technique for monitoring hematological response, and should be used as a guide in therapy. It should be recognized that iron storage may lag behind the appearance of normal blood morphology. After administration of iron dextran complex, evidence of a therapeutic response can be seen in a few days as an increase in the reticulocyte count. Although serum ferritin is usually a good guide to body iron stores, the correlation of body iron stores and serum ferritin may not be valid in patients on chronic renal dialysis who are also receiving iron dextran complex. Although there are significant variations in body build and weight distribution among males and females, the accompanying table and formulas represent a convenient means for estimating the total iron required. This total iron requirement reflects the amount of iron needed to restore hemoglobin concentration to normal or near normal levels plus an additional allowance to provide adequate replenishment of iron stores in most individuals with moderately or severely reduced levels of hemoglobin. It should be remembered that iron deficiency anemia will not appear until essentially all iron stores have been depleted. Therapy, thus, should aim at not only replenishment of hemoglobin iron but iron stores as well. Note:the table and accompanying formulas are applicable for dosage determinations only in patients with iron deficiency anemia; they are not to be used for dosage determinations in patients requiring iron replacement for blood loss. A patients lean body weight (or actual body weight if less than lean body weight) should be utilized when determining dosage. To calculate a patients weight in kg when lbs are known: patients weight in pounds = weight in kilograms 2. Iron Replacement for Blood Loss: Some individuals sustain blood losses on an intermittent or repetitive basis. Such blood losses may occur periodically in patients with hemorrhagic diatheses (familial telangiectasia; hemophilia; gastrointestinal bleeding) and on a repetitive basis from procedures such as renal hemodialysis. Iron therapy in these patients should be directed toward replacement of the equivalent amount of iron represented in the blood loss. Quantitative estimates of the individuals periodic blood loss and hematocrit during the bleeding episode provide a convenient method for the calculation of the required iron dose. The formula shown below is based on the approximation that 1 mL of normocytic, normochromic red cells contains 1 mg of elemental iron: Replacement iron (in mg) = Blood loss (in mL) x hematocrit Example: Blood loss of 500 mL with 20% hematocrit Replacement Iron = 500 x 0. The test dose should be administered in the buttock using the same technique as described in the last paragraph of this section. If the patient is standing, he/she should be bearing his/her weight on the leg opposite the injection site, or if in bed, he/she should be in the lateral position with injection site uppermost. To avoid injection or leakage into the subcutaneous tissue, a Z-track technique (displacement of the skin laterally prior to injection) is recommended. Parenteral drug products should be inspected visually for particulate matter and discoloration prior to administration, whenever the solution and container permit. Defects9 9 Pancytopenia is a common haematological condition often encountered in day to day clinical practice. It is defned in the stem cells or in the stroma or microenvironment as a decrease in all the three cell lines of blood viz. Severe pancytopenia is bone marrow hypoplasia, fatal bone marrow aplasia, and defned as absolute neutrophil count < 500/cmm, platelet leukaemias. It can result from failure of production of count < 20,000/cmm, and corrected reticulocyte count < stem cells in bone marrow, infltration of bone marrow 1%. Neutropenia may present with febrile non-immune mediated increased destruction of blood illness due to increased susceptibility to infections. Marrow damage may be caused by infltration Patients with thrombocytopenia may present with of marrow with tumour or fbrosis that crowds normal mucocutaneous bleed or bruising. Tumour or fbrosis that infltrates the be suspected on clinical grounds in any patient presenting marrow may originate in the marrow as in leukaemia with unexplained anaemia, prolonged fever and bleeding or myelofbrosis or be secondary to process originating tendency. The severity of pancytopenia and underlying outside marrow as in metastatic cancer or myelophthisis. Incidence of various disorders causing pancytopenia Pancytopenia usually presents with the clinical sign varies according to geographical distribution and genetic and symptoms of bone marrow failure such as pallor, mutations. Main causes of pancytopenia in our country easy fatigability, dyspnoea, bleeding or bruising, and are megaloblastic anaemia due to nutritional defciencies, increased tendency to infection. As platelets have shortest hypersplenism (congestive splenomegaly, malaria, half life, platelet count is frst to be afected leading to and leishmaniasis), aplastic anaemia, myelodysplastic thrombocytopenia. Mucocutaneous bleed is typical syndrome, subleukaemic leukaemias, military manifestation of decreased platelet count with petechial tuberculosis, multiple myeloma, paroxysmal nocturnal haemorrhages in the skin and mucous membrane. Epistaxis, haematuria, gastrointestinal bleeding, According to a study of 200 cases of pancytopenia menorrhagia, and rarely intracranial bleeding are the conducted by Khunger et al at a large general hospital presenting features of thrombocytopenia. Early megaloblastic anaemia seen in 72% cases, followed manifestation of neutropenia is often a sore throat, or chest by aplastic anaemia (14%). The other causes included or soft tissue infection with poor response to antibiotics. In another Normal marrow has tremendous capacity to increase prospective study of 104 pancytopenic patients conducted the output of peripheral blood cells whenever necessary by Gayatri and Rao at a teaching institute in South India for with the help of growth factors and cytokines. All the a period of two years, commonest cause of pancytopenia peripheral cells arise from common progenitor pluripotent was megaloblastosis (74%) followed by aplastic anaemia cells having enormous capacity of self renewal. Vitamin B defciency may also cause12 451 conducted by Jain and Naniwadekar at a tertiary care subacute combined degeneration of cord and psychiatric hospital in Maharashtra hypersplenism (29. In this signifcant anaemia and neurological defcit is thought to study a male preponderance was observed, male to female be rare. In an analysis of 166 Hypersplenism is characterized by splenomegaly, cases of pancytopenia conducted by Kumar et al at two cytopenia(s), normal or hyperplastic bone marrow, tertiary care hematology centers where patients receiving and a response to splenectomy. In hypersplenism myelotoxic chemotherapy or those with leukaemic cells there is peripheral pooling and destruction of cells in peripheral blood smears were excluded from the in enlarged spleen resulting in pancytopenia. Causes study, it was observed that aplastic anaemia (49 cases) of hypersplenism include congestive splenomegaly was most common cause followed by megaloblastic (cirrhosis, congestive heart failure), malaria, hyperreactive anaemia (37cases), aleukaemic leukaemia or lymphoma malarial splenomegaly, leishmaniasis, thalassaemia, (30 cases), and hypersplenism (19 cases). Hypersplenism can rarely be was not commonest cause of pancytopenia in these series idiopathic. Megaloblastic anaemia is a Acquired aplastic anemia predominant cause of pancytopenia in India because Congenital aplastic anaemia (Fanconis anaemia) of high prevalence of nutritional anaemia in Indian Some myelodysplasias Acute myeloid leukaemia Table 1: Causes of pancytopenia with cellular bone marrow Acute lymphoid leukaemia Primary bone marrow Secondary to systemic disease Lymphoma of bone marrow disease Myelodysplasia Vitamin B defciency, folate12 defciency Table 3: Causes of Vitamin B12defciency Paroxysmal nocturnal Hypersplenism Food Decreased consumption-vegan diet, haemoglobinuria cobalamin malabsorption (common in elderly) Myelophthisis Alcoholism Stomach Pernicious anaemia, atrophic gastritis, Myelofbrosis Sepsis, enteric fever gastrectomy, gastric bypass, H. Acute lymphoblastic transient pancytopenia during the course of illness and leukaemia is the most common acute leukaemia in has also been associated with aplastic anaemia. Clinical history and symptoms usually indicate associated with pancytopenia and aplastic anaemia is bone marrow failure. Whereas hepatitis B and hepatitis C are dizziness, bleeding, easy bruising, and recurrent common causes; Epstein-Barr virus, cytomegalovirus, infections. Cytogenetic abnormalities are prognostically and rarely hepatitis A and dengue virus can also cause important and afect patient management. Disseminated miliary haematological diseases characterized by cytopenias tuberculosis is known to cause pancytopenia. Although associated with abnormal appearing cellular marrow pancytopenia is a rare presentation of tuberculosis, it producing inefective red blood cells. They are characterized by disturbance of diferentiation Wuchereria bancrofti is an endemic flarial nematode spread and maturation, and by changes in the bone marrow by a mosquito vector. Leukopenia is also common and almost always causing hypoplasia of bone marrow leading to consists of lymphopenia and not granulocytopenia. It is a potentially life Idiopathic cytopenia of undetermined signifcance threatening failure of bone marrow. Triggering factors may include drugs, viruses, that recognizes patients who present with cytopenias and toxins but most cases are idiopathic. In addition to haemolysis, there is often pancytopenia established when all possible diferential diagnosis have and a risk of venous thrombosis. In addition liver function 453 Table 5: Common drugs causing pancytopenia test, viral markers for hepatitis, coagulation profle, a. These cells are an immunosuppressive drug used for treatment of reticulocytes that have been prematurely released from various diseases, usually causes leucopenia and rarely the bone marrow. Patients typically have short stature, cafe megaloblastic anaemia bone marrow shows megaloblastic au lait spots, and anomalies involving thumb, radius, erythroid hyperplasia, sieved nuclear chromatin, and genitourinary tract. Dyskeratosis congenita is asynchronous nuclear maturation, bluish cytoplasm with characterized by mucous membrane leukoplakia, cytoplasmic blebs. Giant metamyelocytes and band forms dystrophic nails, reticular hyperpigmentation, and are predominant in granulocyte series. The causes of pancytopenia marrow is hypercellular with reduced erythroid and are diverse. Atention must be paid to history of the megakaryocytic series and majority of cells are myeloblast patient and the family. Normally, reticulocytes are disorders, or connective tissue disorder is important.
