mitral stenosis is associated with:

malar flush
- due to back pressure of blood into pulmonary system
- causing rise in CO2 and vasodilation
atrial fibrillation
- caused by left atrium struggling to push blood through stenotic valve, causing strain, electrical disruption and resulting in fibrillation

mitral regurgiation results in:

pan-systolic high pitched whistling murmur
murmur radiates to left axilla

causes:

Idiopathic weakening of the valve with age
Ischaemic heart disease
Infective Endocarditis
Rheumatic Heart Disease
Connective tissue disorders such as Ehlers Danlos syndrome or Marfan syndrome

OE: slightly flushed, temp 37.3, 88bpm, blood pressure 104/72.

Palpation of abdomen: mild tenderness in LIF.

13 y/o underweight female.

Haemglobin 80 (115-165)
MCV 110 (80-96)

strictly vegan. not yet started her periods.

most appropriate treatment?

Hydroxocobalamin (vit b12) and folic acid

notes:
Microcytic anaemia (low MCV indicating small RBCs)
Normocytic anaemia (normal MCV indicating normal sized RBCs)
Macrocytic anaemia (large MCV indicating large RBCs)

large MCV –> macrocytic anaemia

-> 1. megaloblast
-> 2. non-megaloblast

megaloblast
- —-> B12 deficiency (e.g. pernicious)
- —-> folate (e.g. diet)
non-megaloblast
- —-> alcohol
- —-> reticulocytosis
- —-> liver disease
- —-> hypothyroidism

four key features of myeloma

CRAB

C- calcium elevated

R- renal failure

A - anaemia (from replacement of bone marrow, normocytic)

B- bone lesions

Perform initial investigations:

FBC (low white blood cell count in myeloma)
Calcium (raised in myeloma)
ESR (raised in myeloma)
Plasma viscosity (raised in myeloma)
If any of these are positive or myeloma is still suspected do an urgent serum protein electrophoresis and a urine Bence-Jones protein test.

B – Bence–Jones protein (request urine electrophoresis)
L – Serum‑free Light‑chain assay
I – Serum Immunoglobulins
P – Serum Protein electrophoresis
Bone marrow biopsy is necessary to confirm the diagnosis of myeloma and get more information on the disease.

apart from miscarriage what is another differential:

cervical ectropion

do transvaginal USS to confirm

Cervical ectropion occurs when the columnar epithelium of the endocervix (the canal of the cervix) has extended out to the ectocervix (the outer area of the cervix)

The transformation zone is the border between the columnar epithelium of the endocervix (the canal), and the stratified squamous epithelium of the ectocervix (the outer area of the cervix visible on speculum examination).
