Endoscopic Dacryocystorhinostomy
Endoscopic Dacryocystorhinostomy samer kareem 7,133 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.

Scoliosis
Scoliosis samer kareem 18,804 Views • 2 years ago

If you look at someone’s back, you’ll see that the spine runs straight down the middle. When a person has scoliosis, their backbone curves to the side. The angle of the curve may be small, large or somewhere in between. But anything that measures more than 10 degrees is considered scoliosis. Doctors may use the letters “C” and “S” to describe the curve of the backbone. You probably don’t look directly at too many spines, but what you might notice about someone with scoliosis is the way they stand. They may lean a little or have shoulders or hips that look uneven. What Causes Scoliosis? In as many as 80% of cases, doctors don’t find the exact reason for a curved spine. Scoliosis without a known cause is what doctors call “idiopathic.” Some kinds of scoliosis do have clear causes. Doctors divide those curves into two types -- structural and nonstructural. In nonstructural scoliosis, the spine works normally, but looks curved. Why does this happen? There are a number of reasons, such as one leg’s being longer than the other, muscle spasms, and inflammations like appendicitis. When these problems are treated, this type of scoliosis often goes away.

Heparin Induced Thrombocytopenia (HIT)
Heparin Induced Thrombocytopenia (HIT) samer kareem 9,366 Views • 2 years ago

All forms of heparin (including low-molecular-weight heparin such as enoxaparin) must be stopped immediately in patients with suspected heparin-induced thrombocytopenia (HIT) while awaiting diagnostic confirmation. Patients with HIT remain at high risk of thrombosis even after discontinuation of heparin. Therefore, an alternate, rapidly acting, non-heparin anticoagulant such as direct thrombin inhibitor (eg, argatroban, bivalirudin) must be started immediately.

Cerclage is indicated in a patient with a history of painless cervical dilation and a second trimester loss. It is also indicated in a patient with a history of preterm birth and a short cervix found on ultrasound between 16-24 weeks gestation.

Complex Regional Pain Syndrome
Complex Regional Pain Syndrome samer kareem 7,783 Views • 2 years ago

This syndrome was previously known as reflex sympathetic dystrophy, algodystrophy, causalgia, Sudeck atrophy, transient osteoporosis, and acute atrophy of bone. Usually occurring after an injury, CRPS presents with pain out of proportion to the injury, temperature change, edema, and abnormal skin color. Type I CRPS (90% of CRPS cases) occurs without a definable nerve lesion, while type II occurs with a definable nerve lesion. The pathogenesis is likely due to an injury causing increased sensitivity to sympathetic nerves, an abnormal response to and sensation of pain, and increased neuropeptide release causing burning pain to light touch (allodynia).

Atrioventricular Septal Defect - AV Canal
Atrioventricular Septal Defect - AV Canal samer kareem 9,625 Views • 2 years ago

An atrioventricular septal defect (AVSD) is a heart defect in which there are holes between the chambers of the right and left sides of the heart, and the valves that control the flow of blood between these chambers may not be formed correctly. This condition is also called atrioventricular canal (AV canal) defect or endocardial cushion defect. In AVSD, blood flows where it normally should not go. The blood may also have a lower than normal amount of oxygen, and extra blood can flow to the lungs. This extra blood being pumped into the lungs forces the heart and lungs to work hard and may lead to

Antiarrhythmics are drugs that are used to treat abnormal heart rhythms resulting from irregular electrical activity of the heart. There are many different types of antiarrhythmic drugs. Examples include: Amiodarone (Cordarone) Flecainide (Tambocor) Procainamide (Procanbid) Sotalol (Betapace) In addition, there are other types of heart drugs that can be used to treat arrhythmias, including: Beta-blockers such as metoprolol or Toprol XL, which reduce the heart's workload and heart rate. Calcium channel blockers such as verapamil or Calan, which also reduces the heart rate.
