•ACUTE GASTRIC DILATATION
-It is an enormous acute dilatation of stomach with atonic gastric wall without peristalsis.
-Stomach distends enormously occupying most of the abdomen and pelvis causing sequestration of lots of fluid resulting in hypovolaemia.

•What are the causes of anemia in CKD?
-Anemia is common in CKD, correlates with the severity of renal failure.
-It is usually normocytic and normochromic.
-The mechanisms are:
1-Erythropoietin deficiency (most significant)
2-Diminished erythropoiesis due to toxic effects of uremia on bone marrow suppression. Also by PTH, ACE inhibitor
3-Reduced dietary intake and absorption of hematinics (iron, vitamin B12, folic acid).
4-Increased red cell destruction (may also be during hemodialysis due to mechanical, oxidant and thermal damage)
5-Increased blood loss due to capillary fragility, poor platelet function, occult gastrointestinal bleeding and blood loss during hemodialysis.
6-Erythropoietin alpha therapy may cause anemia (by pure red cell aplasia).

In HIV&AIDS:
About Vaccines.
-All patients should be given a conjugate pneumococcal vaccine and annual influenza vaccination. Hepatitis B vaccination should be given to those who are not immune.
-In the UK, the following additional vaccines are also recommended:
• hepatitis A: in those at risk
• human papillomavirus: in people <
40 years old
• measles, mumps and rubella (MMR): in those with negative measles serology
• meningococcus: in people < 25 years old, those with asplenia or complement deficiency, during outbreaks
• diphtheria/tetanus/acellular pertussis (dTaP)/inactivated poliovirus vaccine (IPV): meeting general indications
• chickenpox: if seronegative; those who are seropositive should receive the shingles vaccine.
Bacille Calmette–Guérin (BCG) is contraindicated in all HIV-infected people.
