[reiterated L1 stage growth]

[lack of L1 stage growth]

lin-4 negatively regulates lin-14

Victor Ambros

Gary Ruvkun

lin-4 is unlikely to encode a protein.

lin-4 encodes two small RNA transcripts.

 There is partial complementarity between the lin-4 noncoding RNA and multiple elements in the lin-14 3’UTR.

Down-regulation of lin-14p occurs at a post-transcriptional step.

lin-4 and lin-14  3'-UTR is involved in the regulation.

(RAAS, sympathetic)

  • SAAG: serum albumin - ascitic albumin
  • SAAG >= 1.1 g/dL: Ascites caused by portal hypertension

  • SAAG < 1.1 g/dl: Other causes (TB, carcinomatosis, pancreatitis, ...)

Ascites

Spontaneous Bacterial Peritonitis (SBP)

  • In hospitalized patients with cirrhosis and ascites, SBP can occur in up to 30% of individuals. (Harrison)
    • ​Rare in patients without cirrhosis.
  • ​Pathophysiology: Bacterial Translocation
    • intestinal bacterial overgrowth, alterations of the intestinal mucosal barrier, deficiencies of the local immune response

    • Common Pathogen: E. coli, Klebsiella, Streptococcus

  • Diagnosis
    • ​Ascitic PMN(neutrophils) >= 250/\(\mu L\)
    • Positive culture result
    • Absence of secondary causes of peritonitis

Harrison's Principles of Internal Medicine, 21st Edition

Spontaneous Bacterial Peritonitis: Pathogenesis, Diagnosis, Treatment. Florin Alexandru Cãruntu , Loredana Benea, 2006

Ascitic Fluid Analysis

  • Lymphocyte Predominant: TB
  • Lipase/Amylase: pancreatic damage
    • amylase > 1000 or 5x serum concentration
  • Cytology: Malignancy
  • RBC: 
    • High RBC: malignancy, trauma
    • Substract 1 neutrophil/750 RBC

Conclusion?

The patient's ascites and SBP are complications of liver cirrhosis, where the SBP might contribute to the development of ascites.

Questions

1. Why did the ascites developed so quickly after the surgery?

2. Why were there two organisms cultured? May the peritonitis be secondary?
(Harrison : If more than two organisms are identified, secondary bacterial peritonitis due to a perforated viscus should be considered.)

  • fluid shift in small intestine

VIP

GIP

GLP-1

  • hypovolemia

GLP-1

Treatment: Diet
Similar for early/late dumping syndromes

  • Small, frequent meals
  • Liquids should be withheld until 30 minutes after the meal
  • Avoid simple sugar and milk products
  • Low GI, fiber-rich food
  • Adequate protein intake

Treatment: Octreotide
a somatostatin analog

  • inhibit secretion of insulin, glucagon, gastrin, secretin, VIP,...
  • reduce secretion of fluids by the intestine and pancreas
  • reduce gastrointestinal motility

Question

3. 什麼是傾倒症候群? 發生的原因為何? 要如何預防和治療? 和術後血糖的改善有關嗎?
