Microsurgical Suturing
Microsurgical Suturing samer kareem 1,524 Views • 2 years ago

At first, grasping the needle is difficult because it will have a tendency to want to jump around. What can oftentimes help is to get hold of the thread with the left-hand forceps at a point 2 to 3 cm away from the needle. Dangle the needle until it just comes to rest on the surface. This will then allow you to use the angulated needle holder to grab the needle easily. Your needle is in a stable position if it is set up to 90 degrees to the axis of the tips of the forceps. You can make minor corrections by touching the needle with your left-hand forceps, or by partially relaxing your grip and nudging the needle tip against another firm object. You should hold the needle just behind its midpoint (If you hold it too near the tip, it will point downward. If you hold it too near the thread end, it will point upward.).

Endoscopic Dacryocystorhinostomy
Endoscopic Dacryocystorhinostomy samer kareem 7,144 Views • 2 years ago

Dacryocystorhinostomy (DCR) is a procedure performed for the treatment of tearing (epiphora) due to blockage of the nasolacrimal duct. Tears originate in the lacrimal gland, located at the upper outer margin of the eye. As tears cross the eye with each blink, they are directed into small openings in the eyelids called puncta. From this point, tears travel through a pathway known as the canalicular system into the lacrimal sac. The lacrimal sac is located between the eye and the nose, and funnels tears into the nasal cavity through the nasolacrimal duct (Figure 1). As this is quite a long path for tears to travel, there can be many causes of excessive tearing. Blockage of the nasolacrimal duct is one common cause, and can be treated by creating a direct opening from the lacrimal sac into the nasal cavity in a procedure known as DCR. The evaluation and management of tearing may involve both an ophthalmologist and an otolaryngologist.

Chordoid meningioma
Chordoid meningioma samer kareem 14,365 Views • 2 years ago

Chordoid meningioma, classified as atypical meningioma according to the World Health Organisation (WHO) classification, is a rare subtype, which represents only 0.5% of all meningiomas and is associated with a high incidence of recurrence. Multiple intracranial meningiomas are rare in non-neurofibromatosis patients. We present a female patient with both of these rare types of meningioma. The patient presented with two concurrent intracranial meningiomas, with one a meningotheliomatous subtype and the other a chordoid meningioma. Given the wide array of histological differential diagnoses in chordoid meningioma, immunohistochemistry has a significant role to play in differentiating them. Recurrence in chordoid meningioma can be generally predicted based on the extent of resection, the percentage of chordoid element, and proliferation indices.

Spina Bifida. NTD samer kareem 1,659 Views • 2 years ago

Spina bifida is a condition that affects the spine and is usually apparent at birth. It is a type of neural tube defect (NTD). Spina bifida can happen anywhere along the spine if the neural tube does not close all the way. When the neural tube doesn’t close all the way, the backbone that protects the spinal cord doesn’t form and close as it should. This often results in damage to the spinal cord and nerves. Spina bifida might cause physical and intellectual disabilities that range from mild to severe. The severity depends on: The size and location of the opening in the spine. Whether part of the spinal cord and nerves are affected.
