Study Notes
HematologÃa
- Corpuscles have normal values that are important to know to differentiate between anemia types (microcytic, normocytic, hypochromic)
- Reticulocytes should not be abundant in peripheral blood, but their presence can suggest myeloid and lymphoid series
- Blood cell types: platelets, red blood cells, granulocytes, monocytes, and lymphocytes (B and natural killer cells)
SemiologÃa en HematologÃa
- Important to consider patient's ethnicity, sex, and age when diagnosing hematological diseases
- Ethnicity: certain diseases are more common in certain ethnic groups (e.g., anemia drepanocÃtica in people of African descent)
- Sex: some diseases are linked to sex chromosomes (e.g., hemophilia)
- Age: pediatric patients may have different anemia types than adult patients (e.g., anemia ferropénica in infants)
Patient History
- Important to ask about:
- Ethnicity
- Sex
- Age
- Occupation (e.g., exposure to toxic substances)
- Residence place (e.g., different blood groups are more common in different regions)
- Dietary habits (e.g., vegetarianism can lead to vitamin B12 deficiency)
- Lifestyle habits (e.g., promiscuity, drug abuse, smoking)
- Family medical history (e.g., inherited diseases)
- Personal medical history (e.g., previous diseases, allergies)
Physical Examination
- Important to examine:
- Skin and mucosa (e.g., pallor, jaundice)
- Eyes (e.g., conjunctival pallor)
- Mouth (e.g., angular cheilitis, glossitis)
- Lymph nodes (e.g., swelling, tenderness)
- Abdomen (e.g., hepatomegaly, splenomegaly)
- Skin bleeding or petechiae (e.g., coagulation disorders)
Hematology
- Normal values of corpuscles are crucial in distinguishing between anemia types, including microcytic, normocytic, and hypochromic anemia
- Reticulocytes are normally not abundant in peripheral blood, but their presence can indicate myeloid and lymphoid series disorders
- There are five main types of blood cells: platelets, red blood cells, granulocytes, monocytes, and lymphocytes (including B cells and natural killer cells)
SemiologÃa in Hematology
- Patient's ethnicity, sex, and age are essential considerations in diagnosing hematological diseases
- Certain ethnic groups are more prone to specific diseases, such as sickle cell anemia in people of African descent
- Sex chromosomes can influence the development of certain diseases, like hemophilia
- Age is a critical factor, as pediatric patients may exhibit different anemia types compared to adult patients, such as iron deficiency anemia in infants
Patient History
- Important aspects to inquire about in patient history include:
- Ethnicity and its relationship to specific diseases
- Sex and its link to sex chromosome-related diseases
- Age and its impact on disease development
- Occupation and potential exposure to toxic substances
- Residence place and its influence on blood group distribution
- Dietary habits, such as vegetarianism, and their impact on vitamin deficiencies
- Lifestyle habits, including promiscuity, drug abuse, and smoking
- Family medical history, including inherited diseases
- Personal medical history, including previous diseases and allergies
Physical Examination
- Key areas to examine include:
- Skin and mucosa for signs of pallor or jaundice
- Eyes for conjunctival pallor
- Mouth for angular cheilitis or glossitis
- Lymph nodes for swelling or tenderness
- Abdomen for hepatomegaly or splenomegaly
- Skin for bleeding or petechiae, indicating coagulation disorders
