Conditions required for safe percutaneous liver biopsy:

• Prothrombin time < 4 secs prolonged
• Platelet count > 80 × 109/L
• Exclusion of bile duct obstruction, localised skin infection, advanced chronic obstructive pulmonary disease, marked ascites and severe anaemia.

#Liver
What are the causes of fluctuating jaundice?

1-Choledocholithiasis
2-Choledochal cyst
3-Sometimes in primary sclerosing cholangitis
4-Hemolytic jaundice
5-Wilson disease
6-Gilbert’s syndrome
7-Benign recurrent intrahepatic cholestasis (BRIC)
8-Recurrent pancreatitis.

#Liver
What are the causes of progressive jaundice?

1-Carcinoma of the head of the pancreas
2-Cholangiocarcinoma
3-Primary biliary cirrhosis
4-Primary sclerosing cholangitis.

#Liver
What are the intrahepatic causes of cholestatic (obstructive) jaundice

1-Primary biliary cirrhosis
2-Primary sclerosing cholangitis
3-Viral hepatitis (especially HEV)
4-Drugs and alcohol
5-Autoimmune hepatitis
6-Cystic fibrosis
7-Postoperative
8-Benign recurrent intrahepatic cholestasis
9-Pregnancy.

#Liver
What are the congenital nonhemolytic hyperbilirubinemia?

1.Gilbert’s syndrome (unconjugated hyperbilirubinemia)

2.Crigler-Najjar syndrome (unconjugated hyperbilirubinemia)

3. Dubin-Johnson syndrome (conjugated hyperbilirubinaemia)

4. Rotor’s syndrome (conjugated hyperbilirubinemia).

#Liver
Gilbert’s syndrome:


-It is inherited as autosomal dominant.

-There is reduction of glucuronyl transferase and abnormality in uptake of bilirubin.

-Mild jaundice, especially with fasting.

-No treatment is necessary, only reassurance is sufficient.


#Liver
Crigler-Najjar syndrome:

There are two types:
Type I is inherited as autosomal recessive.
-There is absence of glucuronyl transferase, the patient dies in neonatal period due to kernicterus.

Type II is inherited as autosomal dominant.
-There is reduction of glucuronyl transferase.
-The patient usually survives up to adulthood.
-Treatment is by phenobarbitone, ultraviolet light or liver transplantation.


#Liver
Rotor’s syndrome:

- It is inherited as autosomal recessive.

-There is defect in uptake and conjugation bilirubin in the liver.

-Mild disease.

-Urinary total coproporphyrin is increased.

-No treatment is necessary
.

#Liver
Dubin-Johnson syndrome:

- It is inherited as autosomal recessive.

-There is defect in excretion of bilirubin.

-Usually mild disease.

-Liver is black due to deposition of lipofuscin and melanin.

-Urinary coproporphyrin I is increased.

-No treatment is necessary.

#Liver
Remember:

Post-hepatitis syndrome:

-It is seen in anxious patient who complains of malaise, anorexia, nausea, vomiting, right hypochondrial pain or discomfort in the absence of clinical or biochemical evidence of liver disease.
-Reassurance is necessary
.

#Liver
Palmar erythema (liver palm):

-Redness in thenar and hypothenar eminence and pulp of fingers.
-Blanches on pressure.With glass slide, flushes synchronously with pulse.

#Liver
#General
Causes of palmar erythema:

1.Physiological:
-Normal people, may be familial
-Pregnanc
y.

2.Pathological:
-CLD (commonly alcoholic cirrhosis)
-Thyrotoxicosis
-Polycythemia
-Prolonged rheumatoid arthritis
-Chronic leukemia
-Febrile illness.

Mechanism of palmar erythema in CLD:
-Hyperdynamic circulation
-Probably, high estrogen (controversial).

#Liver
#General
Flapping tremor (asterixis):

-It is characterized by irregular, flexion-extension movement of wrist and MCP joints, abduction-adduction of fingers, produced by dorsiflexion of wrist and spreading of the fingers.

-It is called flapping, because of resemblance to a bird flapping its wings.

-It is demonstrated by asking the patient to stretch out arms in front, separate the fingers, dorsiflexion of wrist with fixed forearm by the examiner’s hand.

#Neurology
Features of flapping tremor:

-It is absent at rest, produced by intentional movement, maximum at sustained posture.

-Usually bilateral, and not necessarily synchronous on each side.

-Disappears during coma.

-Occasionally arms, face, neck, tongue,
jaw and eyelids are involved.


#Neurology
Causes of flapping tremor:

1-Hepatic encephalopathy (the commonest cause)
2-Severe cardiac failure
3-Respiratory failure
4-Renal failure
5-Other causes (rare) cerebrovascular accident (CVA), drug toxicity (phenytoin and barbiturate), acute focal parietal or thalamic lesion (vascular) and hypoglycemia.


#Neurology
Mechanism of flapping tremor in CLD:

-It is due to impaired inflow of joint position sense and other afferent informations to the brainstem reticular formation, resulting in rhythmical lapse of postural muscle tone.

#Neurology
#Liver
Causes of Dupuytren’s contracture:

1-Cirrhosis of liver (commonly alcoholic)
2-Alcoholism (itself, not by cirrhosis)
3-Prolonged antiepileptic drug (phenytoin)
4-Manual worker (gardener) and chronic vibration injury
5-Traumatic
6-Familial:
(as autosomal dominant, associated with Garrod’s patch on dorsum of hand)
7-Diabetes mellitus:
(diabetic cheiroarthropathy, confuses with systemic sclerosis)
8-Peyronie’s disease
9-Idiopathic (in many cases).

What are the causes of granuloma in liver?

1-PBC
2-Tuberculosis
3-Sarcoidosis
4-Brucellosis
5-Parasitic (strongyloidiasis)
6-Schistosomiasis
7-Drug (phenylbutazone).

#Liver
Pickwickian syndrome:

-It's called Obesity hypoventilation syndrome.
-Sleep-related hypoventilation disorder
-BMI of ≥ 30 kg/m2 Obesity
-Daytime sleeping.


#Respiratory
GN's in which the COMPLEMENT is low:

1-Lupus nephritis
2-IE
3-Post-infectious GN
4-Cryoglobulinemia
5-HSP
6-MPGN.

Normal complement:
Anti-GBM
1-Good pasture syndrome
2-Anti-GBM renal disease.

#Renal
What are the reversible conditions in obesity?

-Hypothyroidism
-Cushing’s syndrome
-Insulinoma
-Hypothalamic disorder.
