49
Q

Most malignant form of melanoma

A

Nodular melanoma
In the polypoid variant of NODULAR MELANOMA, melanoma cells accumulate in large volume above the skin’s surface. This increase in tumor volume encourages dislodgment of melanoma cells that are carried to superficial lymphatic vessels without invading the reticular dermis; this feature differentiates polypoid melanoma from the nonpolypoid nodular variant. Polypoid melanoma is considered the most malignant form of melanoma

50
Q

Superficial spreading melanoma is the most common form of melanoma. This accounts for approximately 70% of all cases. It is common in young people.

53
Q

Lesch-Nyhan syndrome

A

X-linked recessive disorders, such as Lesch-Nyhan syndrome, occur much more frequently in males. It occurs due to mutations in the HPRT1 gene located on the X chromosome, and is caused by a deficiency of the enzyme hypoxanthine-guanine phosphoribosyltransferase (HGPRT). The HGPRT deficiency causes a build-up of large volumes of uric acid.

54
Q

55
Q

Genu valgum in children

A

While genu valgum is often benign, it is often caused by rickets in children. Rickets results in soft, weak bones in children. Symptoms include vitamin D deficiency, inadequate bone mineralization, bone weakening, and bowing in the lower extremities. The primary cause of congenital rickets is vitamin D deficiency.

56
Q

Severity of disease is associated with age

57
Q

Epoetin alpha (PROCRIT)

A

A male with a hemoglobin level of of 7.6 g/dL would require anemia treatment prior to undergoing midfoot amputation. Epoetin alpha (PROCRIT) is commonly used to treat anemia in those undergoing cancer treatment (chemotherapy and radiation) and chronic kidney disease (but not on dialysis). For those who require dialysis iron should be given with erythropoietin.

58
Q

Gout appearance on microscope

A

Under polarized light and parallel to the axis of the lens, needle-shaped monosodium urate gout crystals display negative birefringence.

61
Q

Anaplastic cells are…

A

Malignant
Anaplastic cells describe cancer cells that divide rapidly with minimal resemblance to normal, healthy cells. Malignant neoplasms that are composed of undifferentiated cells are said to be - anaplastic. Benign cells do not invade surrounding tissues. Metaplastic cells transform from one differentiated cell type to another differentiated cell type. They are cells that change from one cell type to another. Neoplastic cells are cells that grow abnormal, excessive, and autonomously. Neoplasias are often caused by genetic mutations. Neoplasias can be benign or malignant.

62

A

Volkmann’s contracture is compartment syndrome of the forearm. Much like the lower leg, symptoms include: 5 P’s of compartment syndrome: pain, pallor, pulselessness, paresthesias, and paralysis. Of these, pain is the earliest sign. Pain is expressed with passive extension.

66
Q

Manifestations of sickle cell disease

A

Sickle cell disease is the most common autosomal recessive disorder in African-Americans. Patients are predisposed to infections with capsulated organisms (S pneumoniae&raquo_space; H influenzae type b > N meningitidis) dues to functional asplenia from consecutive splenic infarcts. Cardiac complication due to ischemic events typically happen later in life.

67
Q

Primary versus secondary syphilis

73
Q

Chronic hemolytic anemia

A

Sickle cell disease causes a chronic hemolytic anemia. An inherited disorder, the sickle-shaped red blood cells cause vaso-occlusion and are prone to hemolysis, leading to severe pain crises, organ ischemia, and other systemic complications.

74
Q

Green skin and nail rash

A

Acute green skin and nail discoloration can be caused by Pseudomonas aeruginosa infection of the nail plate and skin. Ciprofloxacin would be the most appropriate antibiotic listed for the safe treatment of this patients bacterial infection.
