Small Airways and Asthma Control
Small Airways and Asthma Control samer kareem 4,394 Views • 3 years ago

Asthma was originally described as an inflammatory disease that predominantly involves the central airways. Pathological and physiological evidence reported during the past few years suggests that the inflammatory process extends beyond the central airways to the peripheral airways and the lung parenchyma. The small airways are capable of producing T-helper-2 cytokines, as well as chemokines, and they have recently been recognized as a predominant site of airflow obstruction in asthmatic persons. The inflammation at this distal site has been described as more severe than large airway inflammation. These findings are of great clinical significance, and highlight the need to consider the peripheral airways as a target in any therapeutic strategy for treatment of asthma.

Middle cerebral artery stroke - Axiom Neuro 3D Neurology and Neuroanatomy
Middle cerebral artery stroke - Axiom Neuro 3D Neurology and Neuroanatomy samer kareem 3,166 Views • 3 years ago

Middle cerebral artery syndrome is a condition whereby the blood supply from the middle cerebral artery (MCA) is restricted, leading to a reduction of the function of the portions of the brain supplied by that vessel: the lateral aspects of frontal, temporal and parietal lobes, the corona radiata, globus pallidus, caudate and putamen. The MCA is the most common site for the occurrence of ischemic stroke.[1] Depending upon the location and severity of the occlusion, signs and symptoms may vary within the population affected with MCA syndrome. More distal blockages tend to produce milder deficits due to more extensive branching of the artery and less ischemic response. In contrast, the most proximal occlusions result in widespread effects that can lead to significant cerebral edema, increased intracranial pressure, loss of consciousness and could even be fatal.[1] In such occasions, mannitol (osmotic diuretic) or hypertonic saline are given to draw fluid out of the oedematus cerebrum to minimise secondary injury. Hypertonic saline is better than mannitol, as mannitol being a diuretic will decrease the mean arterial pressure and since cerebral perfusion is mean arterial pressure minus intracranial pressure, mannitol will also cause a decrease in cerebral perfusion. Contralateral hemiparesis and hemisensory loss of the face, upper and lower extremities is the most common presentation of MCA syndrome.[1] Lower extremity function is more spared than that of the faciobrachial region.[2] The majority of the primary motor and somatosensory cortices are supplied by the MCA and the cortical homunculus can, therefore, be used to localize the defects more precisely.it is important to note that middle cerebral artery lesions mostly affect the dominant hemisphere i.e. the left cerebral hemisphere.

Pneumothorax Easy explanation
Pneumothorax Easy explanation samer kareem 1,895 Views • 3 years ago

A pneumothorax occurs when some of the tiny air sacs (alveoli) in a baby's lung become overinflated and burst. This causes air to leak into the space between the lung and chest wall (pleural space). The most common cause of pneumothorax is respiratory distress syndrome. This is a condition that occurs in babies who are born too early (premature). The baby's lungs lack the slippery substance (surfactant) that helps them stay open. Therefore, the tiny air sacs are not able to expand as easily. If the baby is put on a breathing machine (mechanical ventilator), there is extra pressure on the baby's lungs, which can sometimes burst the air sacs.

Keratoderma Blennorrhagicum is a manifestation on the skin that appears in patients diagnosed with reactive arthritis (this condition was previously known as Reiter syndrome). The condition manifests itself by lesions that appear on the skin, initially on the palm of the hands and soles of the feet. The lesions have the tendency to spread, affecting other parts of the body, such as the scrotum, scalp or trunk. Because of their appearance, the lesions might be easily confused with the ones from psoriasis. Keratoderma blennorrhagicum is one of the symptoms that can be used for the clinical diagnosis of reactive arthritis.

Your baby measures about 20.7 inches from head to toe and weighs about 6 pounds. The baby may drop lower in your abdomen, usually assuming the head-down position to prepare for birth. The brain has been developing rapidly, and your baby is practicing blinking. Mom-to-be: Your uterus has grown bigger these last few weeks and is probably up under your ribs. But you're in the home stretch! After this week, you'll see your doctor weekly. You may switch between fatigue and extra bursts of energy. You may also have an achier back and feel heaviness and discomfort in your buttocks and pelvis. Tip of the Week: Start stocking your freezer with foods that can be easily popped into the oven or microwave after you bring your baby home. Chili, casseroles, and other simple dishes can be prepared and frozen ahead of time for use later.

Lumpectomy means that a focal area of cancer is going to be removed. A lot of patients with a lumpectomy don’t need any specific breast reconstruction, explains Dr. Miguel Angel Medina, Director of Microsurgery with Miami Cancer Institute.
Al the end of surgical treatment, all those patients go on to need radiation therapy. For patients who have large breasts, physicians have to take a larger lumpectomy than normal.

Baby Ultrasound early pregnancy
Baby Ultrasound early pregnancy samer kareem 4,063 Views • 3 years ago

Pregnancy ultrasounds are performed mainly using transabdominal ultrasound. For many women, especially after 8 weeks gestation, sufficient information about the baby may be obtained with transabdominal ultrasound only. However, in the early pregnancy, the developing embryo is very small (at 6 weeks gestation, the baby is only 5-9mm long) and a transvaginal ultrasound may be required to get a better image of the baby. Transvaginal ultrasound is safe and commonly performed during all stages of pregnancy, including the first trimester. It will not harm you or your baby.

The procedure is used most often to treat a condition called supraventricular tachycardia, or SVT, which occurs because of abnormal conduction fibers in the heart. Catheter ablation is also used to help control other heart rhythm problems such as atrial flutter and atrial fibrillation.
