Uterine Fibroid - Case Study
History
A 36-year-old African-Caribbean woman has noticed abdominal swelling for 10 months. She has to wear larger clothes and people have asked her if she is pregnant, which she finds distressing having been trying to conceive. She has no abdominal pain and her bowel habit is normal. She feels nauseated when she eats large amounts. She has urinary frequency but no dysuria or haematuria.
Her periods are regular, every 27 days, and have always been heavy, with clots and flooding on the second and third days. She has never received any treatment for her heavy periods.
She has been with her partner for 7 years and despite not using contraception she has never been pregnant.
Examination
The woman has a very distended abdomen. A smooth firm mass is palpable extending from the symphysis pubis to midway between the umbilicus and the xiphisternum (equivalent to a 32-week size pregnancy). It is non-tender and mobile. It is not fluctuant and it is not possible to palpate beneath the mass. On speculum examination it is not possible to visualize the cervix. Bimanual examination reveals a non-tender firm mass occupying the pelvis.
Investigations
Haemoglobin = 6.3 g/dL ( normal = 11.7–15.7 g/dL)
Mean cell volume = 68 fL ( normal = 80–99 fL)
The pelvic ultrasound revealed a large uterine fibroid .
Case Discussion:
Uterine Fibroid (Leiomyoma)
The woman has a large uterine fibroid (leiomyoma). This is causing menorrhagia and hence the microcytic anaemia from iron deficiency. It is also likely that the fibroid is accounting for her infertility history, although this warrants investigation as a separate
problem.
Fibroids are benign tumours of the myometrium which may be extrinsic (subserous) as in this case. Alternatively they may be intramural or submucosal (projecting into the endometrial cavity).

8. What are the specific causes of primary and secondary adrenal failure?
Answers And Discussion
1. What are the general categories of adrenocortical insufficiency?
Adrenocortical insufficiency results primarily from deficient cortisol production and in some cases deficient aldosterone and androgen production by the adrenal gland. Because the adrenal cortex is normally stimulated by pituitary adrenocorticotropic hormone (ACTH; corticotropin), cortisol
deficiency may result from adrenal disease (primary adrenal insufficiency or Addison's disease) or from pituitary or hypothalamic disease with ACTH deficiency (secondary adrenal insufficiency).

A 56-year-old man is seen because of progressive fatigue, dyspnea on exertion, orthopnea, and paroxysmal nocturnal dyspnea.
On physical examination his blood pressure is 160/60 mm Hg. There is no jugular venous distention, but systolic pulsations of the uvula are noted, as is quick collapse of the arterial pulses, which is seen in the nail beds with gentle pressure. The lungs are clear to percussion and auscultation. There is a diffuse and hyperdynamic apex beat that is displaced laterally and inferiorly, soft first and second heart sounds, a loud third heart sound, and a grade 3/6, high-pitched, nearly holodiastolic murmur heard best at the upper left sternal border along with a grade 3/6 systolic ejection type murmur at the upper left sternal border radiating to the carotids. A late diastolic rumble is heard at the apex as well
as a third heart sound.

Answers:
1. What is the most likely valvular lesion in this patient?
This patient has chronic severe aortic regurgitation.
There are many physical signs to look for in the setting of aortic regurgitation, some of which are
seen in this patient. These include
- de Musset's sign (the head bobs with each heartbeat),
- Corrigan's sign or waterhammer pulses,
- Traube's sign (booming systolic and diastolic sounds heard over the femoral arteries),
- Muller's sign (systolic pulsation of the uvula),
- Quincke's sign (capillary pulsations seen in the nail beds), and others.
All of these are signs of large stroke volume and wide pulse pressure characteristic of chronic aortic
regurgitation. The loud 3/6 diastolic murmur heard at the upper left sternal border is the murmur of aortic insufficiency and the systolic murmur is due to turbulent flow across the aortic valve because of the large amount of blood crossing the aortic valve. The mid-to-late diastolic rumble, namely the Austin Flint murmur, is created by rapid retrograde flow from the aorta striking the anterior mitral leaflet. Another explanation for this murmur is that the large volume of regurgitant flow partially closes the mitral valve, creating a late diastolic mitral valve gradient.

There is no history of fever, hoarseness of voice, difficulty in deglutition, contact with TB patients. He smokes about 25 sticks a day for the last 30 years. He used to take some cough syrup and occasionally antibiotics, the name of which he cannot mention.
Examination:
Respiratory System
(Supposing right sided)
Inspection:
- Movement is restricted on right upper chest
- There is radiation mark on the chest (if any).
Palpation:
- Trachea is central in position
- Apex beat is in left 5th intercostal space, just medial to the midclavicular line
- Vocal fremitus is reduced (or absent) in right upper chest
- Pleural rub is present (mention where).
Percussion:
- Percussion note is dull in right upper chest (mention up to which space)
- Upper border of the liver dullness is in the right 5th intercostal space in the midclavicular line
- Cardiac dullness is normal.
Auscultation:
- Breath sound is reduced (or absent)
- Vocal resonance is reduced (or absent)
- Few crepitations (may be present)
- Pleural rub is present (mention where).
Examination of the other systems reveals no abnormalities.
1. What is your diagnosis?
My diagnosis is bronchial carcinoma with metastasis (in right supracalvicular Lymph node).
2. Why bronchial carcinoma?
The patient is elderly and heavy smoker. There is history of cough with hemoptysis and marked loss
of weight. On examination, the patient is emaciated, has generalized clubbing with nicotine stain and
examination of chest shows evidence of mass lesion. All the features are suggestive of bronchial carcinoma.
3. What are your differential diagnoses?
As follows:
- Pulmonary TB
- Other mass lesion (hydatid cyst, dermoid cyst, neurofibroma).
4. Why pulmonary TB is not your primary diagnosis?
This may be pulmonary tuberculosis, because all the features like cough, hemoptysis and weight
loss are present in tuberculosis. However in this case, there is no history of fever or contact with TB
patient. The patient has gross clubbing, enlarged supraclavicular lymph node, which is hard in
consistency and evidence of mass lesion in chest. All these are against pulmonary tuberculosis.

A Previously Healthy 42 Year old Man Presents To The Emergency With Syncope
A previously healthy but inactive 42-year-old man is seen in the ER after a first episode of syncope, which occurred while he was playing basketball.
On questioning, he describes a 2-month history of exertional chest pain. He has not seen a physician during his adult life.
Physical examination reveals the following findings. His supine blood pressure is 116/80 mm Hg without any significant orthostatic change. There is no jugular venous distention, but there are slowly rising, small-amplitude, and somewhat sustained carotid pulses. His lungs are clear. A sustained and slightly laterally displaced apex impulse is noted, as well as a soft first heart sound and a single second heart sound, a prominent fourth heart sound, and a grade 3/6 harsh, late-peaking, crescendo–decrescendo systolic murmur heard best at the cardiac base and radiating to the carotids with a high-frequency component at the cardiac apex. No clubbing, cyanosis, or edema is noted.
1. What is the most likely valvular lesion in this patient?
2. What is the most likely cause of aortic stenosis in this age-group?
3. What is the average survival of patients w ith uncorrected aortic stenosis
after the onset of syncope?
4. How is the severity of aortic stenosis most accurately determined?
5. What is the best therapy for symptomatic aortic stenosis?
Answers:
1. What is the most likely valvular lesion in this patient?
The history of angina and syncope and the classic physical examination findings make aortic stenosis an almost certain diagnosis in this patient.
The characteristic arterial pulses described have been referred to as pulsus parvus et tardus. The single second heart sound indicates the absence of the aortic component, suggesting severe immobility of the aortic valve. The murmur is also characteristic of aortic stenosis with its crescendo– decrescendo quality and the late peaking. Do not be fooled by the high frequency
component at the cardiac apex. Although the murmur of aortic stenosis is most often heard at the upper cardiac border with radiation to the carotid arteries, the murmur may also radiate to the apex, where it may be mistaken for the murmur of mitral regurgitation.
