Dendritic ulcer is a corneal ulcer that is typically caused by herpes simplex virus (HSV) infection.
The diagnosis is typically made based on clinical presentation, which includes a branching, tree-like appearance of the ulcer on fluorescein staining. The initial management of dendritic ulcers involves topical antiviral medications, such as acyclovir or ganciclovir ophthalmic gel, which can help to shorten the duration of the infection and prevent complications. Additionally, supportive measures such as lubrication and protection of the affected eye may be helpful. It is important to refer patients with dendritic ulcers to an ophthalmologist for further evaluation and management, particularly if the ulcer is large, there is associated inflammation or edema, or if the patient has a history of recurrent or severe infections. Close monitoring and follow-up are essential to ensure that the infection resolves completely and to prevent further damage to the cornea.

The pain started after she ate fatty food. she has had similar but less intense episode that lasted a few hours, exam reveals a + Murphys sign What is the most likely diagnosis?
The most likely diagnosis is acute cholecystitis with positive Murphy's sign.
What is the likely diagnosis for RUQ pain?Based on the given information, the most likely diagnosis for this patient is acute cholecystitis.
Acute cholecystitis is inflammation of the gallbladder, usually caused by an obstruction of the cystic duct by a gallstone. It typically presents with pain in the right upper quadrant (RUQ) of the abdomen that may radiate to the right shoulder or scapula. The pain can be severe and is often accompanied by nausea, vomiting, and fever.The fact that the pain started after the patient ate fatty food is a classic symptom of acute cholecystitis. This is because the gallbladder is responsible for storing and releasing bile, which helps to break down fats in the small intestine. When the cystic duct is obstructed, bile can back up into the gallbladder, causing it to become inflamed and painful.The presence of a positive Murphy's sign is another important clue to the diagnosis of acute cholecystitis. This sign is elicited by placing pressure on the patient's right upper quadrant and asking them to take a deep breath. If they stop breathing due to pain, this suggests inflammation of the gallbladder.The patient's history of previous, less intense episodes is also consistent with acute cholecystitis, as this condition can present with recurrent bouts of pain.In summary, the patient's presentation of RUQ abdominal pain, nausea, vomiting, fever, and a positive Murphy's sign, along with a history of previous episodes of similar pain, all point towards a diagnosis of acute cholecystitis. Further evaluation with imaging studies, such as ultrasound or CT scan, would be necessary to confirm the diagnosis and guide management.

Why is donated blood irradiated?
Donated blood is irradiated as a precautionary measure to prevent graft versus host disease (GVHD) in recipients who have weakened immune systems.
GVHD is a potentially life-threatening condition that occurs when white blood cells from the donor attack the recipient's tissues. Irradiation helps to eliminate T cells in the donated blood that are responsible for GVHD by damaging their DNA and preventing them from multiplying. This process is called "leukocyte reduction."
Irradiation also reduces the risk of transfusion-associated graft-versus-host disease (TA-GVHD) which is caused by undetected T cells in donated blood. This condition occurs when the donor's immune cells recognize the recipient's body as foreign and attack it. Irradiation is therefore recommended for all transfusions, but it is especially important for patients receiving blood from a close relative or a directed donation.
It is worth noting that while irradiation is an effective way to prevent GVHD and TA-GVHD, it can also cause some changes to the blood components, such as a reduction in clotting factors and red cell deformability. These changes are usually minimal and do not affect the safety or efficacy of the transfusion. Overall, irradiation is a crucial step in ensuring the safety of blood transfusions and protecting vulnerable patients from serious complications.

18 yo M boxer presents with severe LUQ abdominal pain that radiates to the left scapula. He had infectious mononucleosis three weeks ago. What the diagnose?
Based on the presented symptoms, the likely diagnosis for the 18-year-old male boxer is splenic rupture. The LUQ abdominal pain that radiates to the left scapula is a classic symptom of splenic rupture.
This condition is characterized by the tearing or rupture of the spleen, which is a vital organ that filters the blood and helps fight infections. Infectious mononucleosis, which the patient had three weeks ago, can cause splenomegaly or enlargement of the spleen. This enlargement can make the spleen more vulnerable to rupture, especially if the patient engages in contact sports or activities that put pressure on the abdomen.It is important to note that splenic rupture is a medical emergency and requires immediate treatment. The patient should be transported to the hospital for evaluation, where diagnostic tests such as ultrasound or CT scan may be performed to confirm the diagnosis. If a splenic rupture is confirmed, surgical intervention may be necessary to repair or remove the spleen.In conclusion, the 18-year-old male boxer's severe LUQ abdominal pain that radiates to the left scapula, along with his recent history of infectious mononucleosis, suggests a diagnosis of splenic rupture. It is important to seek medical attention immediately in cases of suspected splenic rupture.
