Medicine Flashcards
Type of hemoglobin in sickle cell anemia
Sickle Sell anemia
- Hemoglobin SS
- Inherit an S trait from each parent
Nutritional cause of peripheral neuropathy
Thiamine deficiency (Vitamin B1) Pernicious anemia (Vitamin B12 deficiency) Alcoholism
Zinc deficiency
Decreased appetite Growth retardation Diarrhea Hair and nail loss Skin and eye lesions
Post traumatic osteomyelitis
Staph aureus is the most common bacterial organism associated with osteo following trauma
Medications containing sulfa
Furosemide
Bactrim
Silvadene
Rabies
Most common initial symptoms are flu-like symptoms
Fever, headache, general discomfort
Progresses quickly to anxiety, confusion, agitation, abnormal behavior, delirium, hallucination
Ankylosing spondylitis
Seronegative spondyloarthritis, HLA-B 27 positive
More common in young and middle aged males
Bamboo spine
Bilateral grade 2 sacroilitis
Squaring and erosion of vertebrae
NO subchondral sclerosis
Amides
Metabolized by the liver
Contain an i before the “-caine”
Lidocaine, mepivicaine, prilocaine, bupivicaine, ropivicaine
Esters
Metabolized in the blood by pseudoesterase
Do not contain an i before the “-caine”
Procaine, chloroprocaine, tetracaine
von Willebrand disease
Clotting disorder caused by a defective or missing clotting protein - von Willebrand factor
These patients are at a greater risk of easily bruising and excessive bleeding after surgery
Post operative constipation
Loss of appetite
Lethargy
Abdominal tenderness
Contraindications to elective surgery
MI within 6 months
CVA within 2 months
Closure after laceration
Follow 6 hour golden rule to prevent infection
Nickel allergy
Nitinol contains 45% nickel
Stainless steel contains 35%
Titanium and other alloys contain <1% nickel
Thrombophlebitis
Inflammatory process that causes blood to clot and block one or more veins
Most common in lower extremities
Causes erythema, edema, pain
Risks of blood transfusion
Volume overload, hypothermia, hyperkalemia, hypocalcemia, acute transfusion reactions, hypersensitivity and anaphylaxis, and increased risk of infection
Risk of periprosthetic and surgical site infection are also increased during allogenic blood transfusion
Vitamin C deficiency
Periosteal hematomas and petechial hemorrhages are common findings in vitamin C deficiency (Scurvy)
Vitamin D deficiency
Increased risk of skeletal deformity and fractures
Deficiency in children is termed “Rickets”
Leads to insufficient mineralization of newly formed osteoid
Thrombophlebitis
Thrombophlebitis is inflammation of a vein secondary to a localized blood clot, or thrombus. This patient likely has a deep vein thrombosis which may dislodge and occlude the lungs.
Most likely complication of thrombophlebitis is pulmonary embolism
Furosemide and potassium
A normal blood potassium is 3.5 to 5.1 millimoles per liter (mmol/L). Overuse of furosemide may lead to metabolic alkalosis due to hypochloremia and hypokalemia. Hypokalemia increases risk of an abnormal cardiac rhythm
Most important aspect of CPR
Begin CPR. If a pulse is not identified within 10 seconds, immediately begin administering CPR, starting with chest compressions. Compressions should occur at a rate of 100 to 120 compressions per minute, with a depth of 2 inches. Use a compression-to-ventilation ratio of 30 compressions to 2 breaths.
Most common site of hematogenous osteomyelitis in children
Tibia. Explanation: The lower extremity is by far the most common site for location of hematogenous osteomyelitis in children. The two most common sites are femur and the tibia
Kaposi’s sarcoma
Kaposi sarcoma is a type of skin cancer that often begins as a purple skin lesion. Human herpesvirus 8 (HHV8) is found in the lesions of all those affected. Risk factors for Kaposi’s sarcoma include: HIV positive individuals and those with poor immune function. Treatment should include retroviral therapy and referral to radiation/oncology for chemotherapy treatment.
Target range INR for warfarin
The majority of indications for therapeutic INR range is 2.0-3.0.
Cafe au lait
Café au lait spots are most often harmless, but they may be associated with syndromes such as neurofibromatosis and McCune–Albright syndrome. They’re caused by a collection of pigment-producing melanocytes in the epidermis of the skin. Those with McCune-Albright syndrome often develop areas of abnormal scar-like tissue in their bones; polyostotic fibrous dysplasia.
Type I collagen
Found in bone, the most abundant collagen in the body
Type II collagen
Type II collagen is primarily found in hyaline cartilage
Type III collagen
Found in skin, blood vessels, granulation tissue
Type IV collagen
Type IV collagen is a type of collagen found primarily in the skin within the basement membrane zone.
Target cells
Target cells are red blood cells that have the generalized appearance of a shooting target with a bullseye. Thalassemia is an inherited-blood disorder, characterized by diminished hemoglobin and fewer red blood cells in the body than normal. Target cells appear in conditions that cause the surface of the red cell to increase disproportionately to its volume.
