Posterior Elbow Dislocation Reduction
Posterior Elbow Dislocation Reduction samer kareem 1,941 Views • 2 years ago

Posterior dislocations with associated fractures, also known as complex posterior dislocations, often require open reduction and fixation (ORIF). These dislocations are often associated with significant ligamentous injury. In some cases, complex posterior elbow dislocations may be managed with closed reduction. Posterior elbow dislocations that are neglected, as is not uncommon in developing countries, can often be effectively treated with open reduction. [9] Delayed vascular compromise is an important complication after reduction. All patients should be observed for a period of approximately 2-3 hours after reduction. If no evidence of vascular compromise arises, patients can be sent home with appropriate follow-up and instructions to watch for further problems.

HIV Virus Life Cycle and Drug Reaction
HIV Virus Life Cycle and Drug Reaction Magdy 11,448 Views • 2 years ago

Binding and Fusion: HIV begins its life cycle
when it binds to a CD4 receptor and one of two
co-receptors on the surface of a CD4+
Tlymphocyte. The virus then fuses with the host
cell. After fusion, the virus releases RNA, its
genetic material, into the host cell.

Reverse Transcription: An HIV enzyme
called reverse transcriptase converts the singlestranded HIV RNA to double-stranded HIV DNA.

Integration: The newly formed HIV DNA
enters the host cell's nucleus, where an HIV
enzyme called integrase "hides" the HIV DNA
within the host cell's own DNA. The integrated
HIV DNA is called provirus. The provirus may
remain inactive for several years, producing few or
no new copies of HIV

Transcription: When the host cell receives a
signal to become active, the provirus uses a host
enzyme called RNA polymerase to create copies of
the HIV genomic material, as well as shorter
strands of RNA called messenger RNA (mRNA).
The mRNA is used as a blueprint to make long
chains of HIV proteins.

Assembly: An HIV enzyme called protease cuts
the long chains of HIV proteins into smaller
individual proteins. As the smaller HIV proteins
come together with copies of HIV's RNA genetic
material, a new virus particle is assembled.

Budding: The newly assembled virus pushes out
("buds") from the host cell. During budding, the new
virus steals part of the cell's outer envelope. This
envelope, which acts as a covering, is studded with
protein/sugar combinations called HIV
glycoproteins. These HIV glycoproteins are
necessary for the virus to bind CD4 and coreceptors. The new copies of HIV can now move
on to infect other cells.

Acalculous Cholecystopathy - Umbilical Hernia Doctor 9,243 Views • 2 years ago

Patient 65-year-old of age who comes to the medical consultation with pain moderated pain in the right hypochondrium of “several years of evolution” but that it increased one week ago. Also, she shows pain in the umbilical region of “many years of evolution”, that is supported according to the patient - in a constant way.rnTo the examination, we observe an umbilical hernia, apparently divided into two parts. The hernia of the external region measures 25.1 centimeters x 18.0 centimeters and the one that occupies the average region measures 12.0 centimeters x 10.0 centimeters.rnPatient who comes to the medical consultation with moderated pain in the right hypochondrium of one year of evolution but it increased one week ago after eat duck.rnIn the ultrasound scan of the region of the right hypochondrium (patient came having breakfast, that is to say, without previous preparation ) we can observe the liver of 123.8 millimeters high, as well as the porta vein with a diameter of 7.3 millimeters.rnOn having observed the Gallbladder, we think that a side wall is increased in 2.7 mm (hyperechogenic) with several “echogenics points” in the interior (”Biliary Mud”).

The measurements of the gallbladder were: 39.0 x 17.4 millimeters.rnWe can appreciates an echogenic image in the interior that it would make think about stone. The stones are identified as echogenic foci casting acoustic shadowing but but this image did not appear and a re-evaluation is decided in 15 days.

Acalculous cholecystopathy which means disease or condition of the gallbladder without the presence of gallstones. You might also call it functional gallbladder disorder or impaired gallbladder emptying. Some causes may be chronic inflammation, a problem with the smooth muscles of the gallbladder or the muscle of the Sphincter of Oddi being too tight.

REMEMBER:
Umbilical hernia is a congenital malformation, especially common in infants of African descent, and more frequent in boys. An Acquired umbilical hernia directly results from increased intra-abdominal pressure and are most commonly seen in obese individuals.
Presentation:A hernia is present at the site of the umbilicus (commonly called a navel, or belly button) in the newborn; although sometimes quite large, these hernias tend to resolve without any treatment by around the age of 5 years. Obstruction and strangulation of the hernia is rare because the underlying defect in the abdominal wall is larger than in an inguinal hernia of the newborn. The size of the base of the herniated tissued is inversely correlated with risk of strangulation (i.e. narrow base is more likely to strangulate).
Babies are prone to this malformation because of the process during fetal development by which the abdominal organs form outside the abdominal cavity, later returning into it through an opening which will become the umbilicus.
Differential diagnosisrnImportantly this type of hernia must be distinguished from a paraumbilical hernia which occurs in adults and involves a defect in the midline near to the umbilicus, and from omphalocele.

Hemophilia A
Hemophilia A samer kareem 6,691 Views • 2 years ago

Hemophilia A, also called factor VIII (FVIII) deficiency or classic hemophilia, is a genetic disorder caused by missing or defective factor VIII, a clotting protein. Although it is passed down from parents to children, about 1/3 of cases are caused by a spontaneous mutation, a change in a gene. According to the US Centers for Disease Control and Prevention, hemophilia occurs in approximately 1 in 5,000 live births. There are about 20,000 people with hemophilia in the US. All races and ethnic groups are affected. Hemophilia A is four times as common as hemophilia B while more than half of patients with hemophilia A have the severe form of hemophilia.
