Bonjour tout le monde,

Two questions for this one


How Should a Postmenopausal Woman Be Examined?


Question 1
You are following up on the results of routine testing of a 68-year-old G4P3 for her well-woman examination. Her physical examination was normal for a postmenopausal woman. Her Pap smear revealed parabasal cells, her mammogram was normal, lipid profile was normal, and the urinalysis shows hematuria. Which of the following is the most appropriate next step in the management of this patient?

a- Colposcopy
b- Endometrial biopsy
c- Renal sonogram
d- Urine culture
e- No further treatment/evaluation is necessary if the patient is asymptomatic

Pap smear = Frottis Cervico-Vaginal (Pap = Papanicolaou, smear = frottis)


Question 2
A 74-year-old woman presents to your office for well-woman exam. Her last Pap smear and mammogram were 3 years ago. She has hypertension, high cholesterol, and osteoarthritis. She stopped smoking 15 years ago, and denies alcohol use. What is the leading cause of death in women of this patient's age?

a- Alzheimer's disease
b- Breast cancer
c- Cerebrovascular disease
d- Heart disease
e- Lung cance
f- Trauma

osteoarthritis = arthrose (et non pas arthrite car arthrite = arthritis)
Breast = sein
Lung= poumon


Answer 01 :
The answer is d, Urine culture [1,2]
>>> A urinalysis that is positive for blood should be followed up with a urine culture to detect an asymptomatic urinary tract infection before further workup is done or referral to a urologist is made. Parabasal cells on a Pap smear indicate lack of estrogen and are a normal finding in postmenopausal women.

Answer 02 :
The answer is d, heart disease.[1,2]
>>> In order of decreasing incidence, the leading causes of death in women over 65 years old are the following: diseases of the heart, cancer, cerebrovascular diseases, chronic obstructive pulmonary diseases, pneumonia and influenza, diabetes mellitus, accidents, and Alzheimer's disease.

These questions are full of information...

Question 01 :
Is Fruit Juice Causing This Infant's Health Problems?
A 6-month-old infant has been exclusively fed a commercially available infant formula. Upon introduction of fruit juices, however, the child develops jaundice, hepatomegaly, vomiting, lethargy, irritability, and seizures. Tests for urine-reducing substances are positive. Which of the following is likely to explain this child's condition?

a- Tyrosinosis
b- Galactosemia
c- Fructosemia
d- a1-antitrypsin
e- Glucose-6-phosphatase deficiency

jaundice = ictère
seizures = crises convulsives/epileptiques


Answer to Question 01 :
The answer is c, Fructosemia.[1-2]
>>> The patient in the question likely has fructosemia, manifest only when fructose in fruit juice is provided in the diet. Galactosemia, fructosemia, tyrosinosis, and glucose-6-phosphatase deficiency represent diseases in which a congenital deficiency of enzyme causes an interruption of a normal metabolic pathway and an accumulation of metabolic precursors that damage vital organs. Galactosemia (found in milk) and fructosemia (found in fruit juices) produce urinary-reducing substances. The mode of inheritance of galactosemia, fructosemia, and most forms of glucose-6-phosphatase deficiency is autosomal recessive. In galactosemia and fructosemia, errors in carbohydrate metabolism cause the accumulation of toxic metabolites when specific dietary sugars are introduced (lactose in galactosemia; fructose and sucrose in fructosemia). Exclusion of the offending carbohydrate from the diet will prevent liver damage. In tyrosinemia type I, or tyrosinosis, the accumulation of tyrosine and its metabolites is associated with severe involvement of liver, kidney, and central nervous system (CNS). Manifestations of acute liver failure can appear in infancy. A chronic form of the disorder presents as progressive cirrhosis and leads to liver failure or hepatoma. Dietary management does not prevent liver disease. Glucose-6-phosphatase deficiency often presents at 3 to 4 months of age with failure to thrive, hypoglycemia, hepatomegaly, and acidosis. Alpha-1-antitrypsin deficiency causes liver disease through accumulation of an abnormal protein, caused by a single amino acid substitution on chromosome 14. It has a variable presentation, but the following are common in infancy: cholestasis; bleeding into the CNS, GI tract, or at the umbilical stump; and elevation of transaminase concentrations. In childhood, a picture of chronic hepatitis with cirrhosis and portal hypertension is seen.

Question 02 :
A 12-year-old healthy Jewish girl is found on routine blood count to have a mild anemia, leukopenia, and thrombocytopenia. Physical examination reveals an enlarged spleen. An x-ray of the femur is described as "appearing to be an Erlenmeyer flask." Bone marrow examination shows abnormal cells. The diagnosis can be confirmed by measurement of activity of which of the following?

a- Sphingomyelinase activity
b- Hexosamidase A
c- Sulfatase A
d- Glucocerebrosidase
e- Ceramide trihexosidase

Jewish = juive
enlarged spleen = splenomegalie
x-ray = radiographie standard
Erlenmeyer flask = flacon d'Erlenmeyer
Bone marrow = Moelle osseuse

Answer to Question 02 :
The answer is d, Glucocerebrosidase.[3-4]
>>> Gaucher disease is characterized by a glucocerebrosidase deficiency, which causes an abnormal accumulation of glucocerebroside in the reticuloendothelial system. Bone marrow aspirate shows the typical Gaucher cells engorged with glucocerebroside. Replacement of marrow with these cells leads to anemia, leukopenia, and thrombocytopenia. The liver and spleen can also be involved. Serum acid phosphatase is elevated. X-ray demonstrates an Erlenmeyer-flask appearance of the long bones. The diagnosis of Gaucher disease is confirmed by the absence of glucocerebrosidase activity in leukocytes, in cultured skin fibroblasts, and in liver cells. Prenatal diagnosis by enzyme analysis is now possible. In the most common form of Gaucher disease, adult type I, there is no involvement of the central nervous system. Therefore, MRI of the brain is not indicated.

Sphingomyelinase deficiency causes type A Niemann-Pick disease; hexosaminidase A deficiency causes Sandhoff disease; sulfatase A deficiency causes juvenile metachromatic leukodystrophy; and serum trihexosidase causes Fabry disease

Hi,

Question 01 :


A 17-year-old boy is brought to the emergency department by his parents with the complaint of coughing up blood. He is stabilized, and his hemoglobin and hematocrit levels are determined to be in the safe range. During his hospitalization, he is noted to have persistently elevated blood pressures, and his urinalysis is remarkable for hematuria and proteinuria.


You are suspicious the patient has which of the following?

a- Hemolytic-uremic syndrome
b- Goodpasture syndrome
c- Nephrotic syndrome
d- Poststreptococcal glomerulonephritis
e- Renal vein thrombosis


Coughing up blood = hemoptysis = hémoptysie.

Answer to Question 01 :

---> The answer is b, Goodpasture syndrome.

The patient in the question has a classic description of Goodpasture syndrome, a rare disease in children. The pulmonary hemorrhage can be life-threatening and the renal function progressive. Diagnosis is suggested by kidney biopsy and finding antibodies to the glomerular basement membrane.

Answer to Question 02 :

The answer is c, Trimethadione.

The patient described appears to have nephrotic syndrome (protein excretion of greater than 3.5 g/24 h). Drug-related nephrotic syndrome has been described in connection with the use of trimethadione, penicillamine, captopril, probenicid, ethosuximide, methimazole, lithium, procainamide, chlorpropamide, phenytoin, paramethadione, tolbutamide, some of the nonsteroidal anti-inflammatory drugs (NSAIDs), and certain heavy metals (e.g., gold, mercury-containing medications).

NSAIDs = AINS

Question 03 :

A 1-year-old child presents with failure to thrive, frequent large voids of dilute urine, excessive thirst, and three episodes of dehydration not associated with vomiting or diarrhea. Over the years, other family members reportedly have had similar histories.


Which of the following is the most likely diagnosis?

a- Water intoxication
b- Diabetes mellitus
c- Diabetes insipidus
d- Child abuse
e- Nephrotic syndrome

large voids of dilute urine = polyuria = polyurie.

Answer to Question 03 :

The answer is c, Diabetes insipidus.

Nephrogenic diabetes insipidus is a hereditary congenital disorder in which the urine is hypotonic and produced in large volumes because the kidneys fail to respond to antidiuretic hormone. Most North American patients thus involved are descendants of Ulster Scots who came to Nova Scotia in 1761 on the ship Hopewell. Males are primarily affected, through an X-linked recessive inheritance causing inactivating mutation of the vasopressin V2 receptor; autosomal dominant and recessive forms are also known. The disorder is felt to result from primary unresponsiveness of the distal tubule and collecting duct to vasopressin.

Although the condition is present at birth, the diagnosis is often not made until several months later, when excessive thirst, frequent voiding of large volumes of dilute urine, dehydration, and failure to thrive become obvious. Maintenance of adequate fluid intake and diet and use of saluretic drugs are the bases of therapy for this incurable disease.

Water intoxication would not present with episodes of dehydration; diabetes mellitus rarely presents with a protracted course in such a young child (it is usually a more acute illness and often with vomiting). Child abuse would be unlikely, especially with a family history as noted. Nephrotic syndrome would be expected to present with other signs such as edema and proteinuria.

A vous.

The answer is a, Urinalysis and culture.

When patients present with urinary incontinence, a urinalysis and culture should be performed. In patients diagnosed with a urinary tract infection, treatment should be initiated and then the patient should be reevaluated. It is not uncommon for symptoms of urinary leakage to resolve after appropriate therapy. After obtaining the history and physical examination and evaluating a urinalysis (including urine culture), initial evaluation of the incontinent patient includes a cystometrogram, check for residual urine volume, stress test, and urinary diary.

A cystometrogram is a test that determines urethral and bladder pressures as a function of bladder volume; also noted are the volumes and pressures when the patient first has the sensation of need to void, when maximal bladder capacity is reached, and so on. Residual urine volume is determined by bladder catheterization after the patient has voided; when urine remains after voiding, infection and incontinence may result.

The answer is c, Obstetric trauma.

The most common cause of fecal incontinence is obstetric trauma with inadequate repair. The rectal sphincter can be completely lacerated, but as long as the patient retains a functional puborectalis sling, a high degree of continence will be maintained. Generally the patient is continent of formed stool but not of flatus. Other causes of fecal incontinence include senility, central nervous system (CNS) disease, rectal prolapse, diabetes, chronic diarrhea, and inflammatory bowel disease.

While rectal prolapse, CNS disease, and senility are thus potential causes of this condition, they can be excluded by the history of the patient in the question. Approximately 20% of all diabetics complain of fecal incontinence. Therapy for fecal incontinence includes bulk-forming and antispasmodic agents, especially in those patients presenting with diarrhea.

All caffeinated beverages should be stopped. Biofeedback and electrical stimulation of the rectal sphincter are other possible conservative treatments. Surgical repair of a defect is indicated when conservative measures fail, when the defect is large, or when symptoms warrant a more aggressive treatment approach.

Question 01 :

Two weeks after a viral syndrome, a 2-year-old child develops bruising and generalized petechiae, more prominent over the legs. No hepatosplenomegaly or lymph node enlargement is noted. The examination is otherwise unremarkable. Laboratory testing shows the patient to have a normal hemoglobin, hematocrit, and white blood count and differential. The platelet count is 15,000/µL.

Which of the following is the most likely diagnosis?

a- von Willebrand disease
b- Acute leukemia
c- Idiopathic (immune) thrombocytopenic purpura
d- Aplastic anemia
e- Thrombotic thrombocytopenic purpura

Bruising = Ecchymoses
Lymph node enlargement = ADP
Platelet = Plaquette

The answer is c, Idiopathic (immune) thrombocytopenic purpura.

In children, idiopathic or immune thrombocytopenic purpura (ITP) is the most common form of thrombocytopenic purpura. In most cases, a preceding viral infection can be noted. No diagnostic test identifies this disease; exclusion of the other diseases listed in the question is necessary.

In this disease, the platelet count is frequently less than 20,000/µL, but other laboratory tests yield essentially normal results, including the bone marrow aspiration (if done). For ITP, platelets are sequestered and destroyed at the spleen by the reticuloendothelial system (RES) that binds self-immunoglobulins attached to the platelet.

Treatment for ITP consists of observation and/or gamma globulin and steroids. Splenectomy is reserved for the most severe and chronic forms. Exogenous IV gamma globulin can work to saturate the RES binding sites for platelet-bound self-immunoglobulin. Thus, there is less platelet uptake and destruction by the spleen.

Aplastic anemia is unlikely if the other cell lines are normal. Von Willebrand disease might be expected to present with bleeding and not just bruising. It is unlikely that acute leukemia would present with thrombocytopenia only. Thrombotic thrombocytopenic purpura is rare in children.


Edit:
bone marrow aspiration = Ponction-aspiration de la moelle osseuse
steroids = corticoides

Question 02 :

An 11-month-old African American boy has a hematocrit of 24% on a screening laboratory done at his well-child checkup. Further testing demonstrates: hemoglobin 7.8 g/dL; hematocrit 22.9%; leukocyte count 12,200/µL with 39% neutrophils, 6% bands, 55% lymphocytes; hypochromia on smear; free erythrocyte protoporphyrin (FEP) 114 µg/dL; lead level 6 µg/dL whole blood; platelet count adequate; reticulocyte count 0.2%; sickle cell preparation negative; stool guaiac-negative; and mean corpuscular volume (MCV) 64 fl.


Which of the following is the most appropriate recommendation?


a- Blood transfusion
b- Oral ferrous sulfat
c- Intramuscular iron dextran
d- An iron-fortified cereal
e- Calcium EDTA

blood smear = frottis sanguin
lead = plomb
sickle cell anemia = drepanocytose
stool guaiac = hemocult [?] (recherche du sang dans les selles)
MCV = VGM

The answer is b, Oral ferrous sulfate.

Response to a therapeutic trial of iron is an appropriate and cost-effective method of diagnosing iron-deficiency anemia. A prompt reticulocytosis and rise in hemoglobin and hematocrit follow the administration of an oral preparation of ferrous sulfate. Intramuscular iron dextran should be reserved for situations in which compliance cannot be achieved, since this treatment is expensive, painful, and no more effective than oral iron.

Dietary modifications, such as limiting the intake of cow's milk and including iron-fortified cereals along with a mixed diet, are appropriate long-term measures, but they will not make enough iron available to replenish iron stores. The gradual onset of iron-deficiency anemia enables a child to adapt to surprisingly low hemoglobin concentrations. Transfusion is rarely indicated unless a child becomes symptomatic or is further compromised by a superimposed infection.

When the iron available for production of hemoglobin is limited, free protoporphyrins accumulate in the blood. Levels of erythrocyte protoporphyrin (EP) are also elevated in lead poisoning. Iron-deficiency anemia can be differentiated from lead intoxication by measuring blood lead, which should be less than 10 µg/dL.

The answer is a, Congenital cytomegalovirus infection.

Thrombocytopenia and hemolytic anemia, as seen in this patient, are common manifestations of the "TORCH" (toxoplasmosis, other, rubella, cytomegalovirus, and herpes simplex) infections as well as congenital syphilis. Both increased platelet destruction and impaired production of platelets may be the mechanisms involved.

Some mothers who have had ITP and who have high levels of antiplatelet antibody in the maternal plasma can give birth to thrombocytopenic infants because of transplacental crossing of antiplatelet IgG antibody. The syndrome of congenital amegakaryocytic thrombocytopenia and bilateral absence of the radii (thrombocytopenia-absent radius, or TAR, syndrome) is a well-known entity.

Maternal ingestion of aspirin can lead to bleeding in the newborn, not as a result of thrombocytopenia but as a consequence of transient impairment of the infant's platelet aggregation. Neither chlamydial conjunctivitis nor nasolacrimal duct stenosis is usually associated with thrombocytopenia.
