- ANS-A midgut volvulus is a trouble of malrotated bowel and consequences in a proximal
bowel obstruction and ischaemia.
Epidemiology
A midgut volvulus of malrotated bowel can doubtlessly arise at any age but in about seventy
five% of cases is inside a month of beginning, most within the first week, and 90% inside 1 yr.
Clinical presentation
Typically the neonate is totally regular for a length earlier than unexpectedly imparting with
bilious vomiting. If the volvulus does now not spontaneously lessen, then the venous obstruction
created by means of the advanced mesenteric vein wrapped across the advanced mesenteric
artery effects in venous obstruction and sluggish onset of ischaemia and eventual necrosis. As
this takes place, the stomach becomes swollen as fluid accumulates inside the lumen of the
bowel, and turns into soft. Eventually peritonitis and surprise grow to be installed.
Forty two-yr-antique guy involves the doctor because of progressive swelling of the legs over
the last 2 months. He has a records of level IIA Hodgkin's disease dealt with 1 year ago with
radiation remedy to the neck and chest. His temperature is 37 C (ninety eight.6 F), blood
pressure is 102/eighty mm Hg, pulse is one hundred ten/min, and respirations are 22/min.
Examination shows jugular venous distention that will increase with proposal. The lungs are
clean to auscultation. Cardiac examination indicates a nondisplaced point of maximal impulse;
heart sounds are remote. An early diastolic sound is heard on the apex. Abdominal examination
shows mild distention with transferring dullness. The liver is pulsatile, and its edge is palpated 4
cm below the proper costal margin. There is 2+ peripheral edema extending up to the knees.
Which of the following is the maximum probably mechanism of this affected person's increased
crucial venous strain?
A) Constrictive pericarditis - ANS-Constrictive pericarditis
The diagnosis on this affected person is Constrictive Pericarditis. It effects from obliteration of
pericardial space and fibrosis of pericardium following an acute fibrinous or serofibrinous
pericarditis or continual pericardial effusion.
Some reasons of constrictive pericarditis are
,Tuberculosis,
Post radiotherapy (31% in USA),
Post surgical (eleven%),
Connective tissue issues, neoplasm, uremia, sarcoidosis, and many others.
Constrictive pericarditis will lead to inability of ventricle to fill properly at some stage in diastole
and might similarly motive the signs and symptoms and signs and symptoms of decreased
cardiac output (fatigue, muscle wasting and so on) and /or signs and symptoms of venous
overload like multiplied JVP, dyspnea, ascites, advantageous Kussmaul's signal (Jugular
venous distention that will increase with suggestion), pedal edema, soft hepatomegaly and
many others. Sharp 'x' and 'y' descent on critical venous tracing is feature of constrictive
pericarditis as is the presence of pericardial knock (early heart sound heard after S2).
A 2-month-old child has uneven gluteal folds. If untreated, the underlying pelvic circumstance
will maximum in all likelihood progress to an erosive arthropathy. Which of the following is the
maximum in all likelihood prognosis?
A- Dislocation
B- Fascitis
C- Ganglion
D- Myositis ossificans
E- Sprain
F- Strain - ANS-A- Dislocation
A 26 year vintage lady with pain and stiffness of each hands. Physical exam shows swelling and
redness of PIP joints. Xray indicates joint area narrowing and marginal erosions of PIP joints.
DIP joints spared. Biopsy show?
A. Necrotizing granulomas
B. Neutrophilic infiltrates
C. Pigmented villonodular synovitis
D. Synovial pannus formation
E. Urate crystals - ANS-D. Synovial pannus formation
DIP spared , swelling, and redness suggests RA
A 38-year-old female visits your office complaining of several years of joint swelling and stiffness
that is worse within the morning and improves during the day. Physical examination exhibits
bilateral deformities at her proximal interphalangeal and metacarpophalangeal joints. The
presence of which of the following on this patient's serum might maximum assist 'rule in' a
diagnosis of rheumatoid arthritis:
1. Rheumatoid factor
, 2. Anti-nuclear antibody
three. Anti-citrullinated protein antibody
4. Anti-centromere antibody
five. Anti-clean muscle antibody - ANS-3. Anti-citrullinated protein antibody
Anti-citrullinated protein antibody (ACPA, or anti-CCP) has greater than 90% specificity for
diagnosing RA
RF is not specific
A 44 yr old female has had ache, swelling, and stiffness in each arms over the past 6
months.The ache and stiffness are worst within the mornings,however signs enhance with
activity.Examination suggests painless nodules on the extensor surfaces of the arms and
tenderness and swelling of the metocarpophalangeal and proximal interphalangeal joints.Which
of the following is involved within the pathologiv procedure affecting her joints?
A)Bacterial invasion
B)Caseating necrosis
C)Crystal deposition
D)Necrotising vasulitis
E)Pannus formation - ANS-E)Pannus formation
A forty seven-year-old woman involves the physician for a habitual health maintenance
examination. She has a 2-12 months records of venous insufficiency and notes every day
swelling of her ankles that worsesn in the evening. She takes no medicines. Her pulse is
80/min, and BP is 160/one hundred mm Hg. Cardiopulmonary examination indicates no
abnormalities. Examination of the decrease extermities display 2+ edema and improved
pigmentation. Which of the following hypertensive pills could maximum probably exacerbate this
affected person's swelling?
A) Atenolol
B) Clonidine
C) Lisniopril
D) Losartan
E) Nifedipine - ANS-E) Nifedipine
Bilateral edema of the lower limbs is one of the maximum not unusual unfavorable results of
DHPs and is in all likelihood related to the vasodilatory mechanism of motion of those drugs.
A 48-12 months-old woman provides with "tight and puffy pores and skin" that includes her
entire frame. Her disease path is swiftly innovative. Given her presumptive prognosis and the
priority for end organ harm, she is cited a dermatologist, pulmonologist, and gastroenterologist.
Which of the subsequent autoantibodies does the patient possibly have?
