Tension Pneumothorax
Tension Pneumothorax samer kareem 4,530 Views • 2 years ago

Tension pneumothorax develops when a lung or chest wall injury is such that it allows air into the pleural space but not out of it (a one-way valve). As a result, air accumulates and compresses the lung, eventually shifting the mediastinum, compressing the contralateral lung, and increasing intrathoracic pressure enough to decrease venous return to the heart, causing shock. These effects can develop rapidly, particularly in patients undergoing positive pressure ventilation.

Achilles Suture Bridge
Achilles Suture Bridge Mohamed Ibrahim 2,431 Views • 2 years ago

The Arthrex SpeedBridge™ is an innovative soft tissue fixation device used in the treatment of Achilles injuries. While standard anchor fixation of the tendon creates only a single point of compression directly over the anchor, the SpeedBridge enables an hourglass pattern of FiberTape® suture to be laid over the distal end of the tendon. This four-anchor construct enables a true knotless repair and a greater area of compression for the Achilles tendon on the calcaneus, improving stability and possibly allowing for earlier return to normal activities.

Hypoglycemia is a common and serious medical emergency which may occur in both daibetic and non-diabetic patients. The signs and symptoms of hypoglycaemia may be present in many individuals, but may also be masked in several individuals due to a condition called hypoglycaemia induced autonomic failure. This presentation aims to deal with the causes, clinical features, diagnosis and management of various causes of hypoglycaemia. The causes of hypoglycaemia may be divided into hypoglycaemia in ill or medicated individuals and hypoglycaemia in previously asymptomatic individuals. A variety of causes are discussed under both headings. Management of hypoglycaemia is also discussed in detail. There is also a brief discussion about management of insulinoma.

Alpha blockers relax certain muscles and help small blood vessels remain open.

Primary Amenorrhea
Primary Amenorrhea samer kareem 2,274 Views • 2 years ago

Amenorrhea is the absence of menstrual bleeding.[1] Amenorrhea is a normal feature in prepubertal, pregnant, and postmenopausal females. In females of reproductive age, diagnosing amenorrhea is a matter of first determining whether pregnancy is the etiology. In the absence of pregnancy, the challenge is to determine the exact cause of absent menses.[2] Primary amenorrhea is the failure of menses to occur by age 16 years, in the presence of normal growth and secondary sexual characteristics. If by age 13 menses has not occurred and the onset of puberty, such as breast development, is absent, a workup for primary amenorrhea should start. Secondary amenorrhea is defined as the cessation of menses sometime after menarche has occurred. Oligomenorrhea is defined as menses occurring at intervals longer than 35 days apart. No consensus has been reached regarding the point at which oligomenorrhea becomes amenorrhea. Some authors suggest the absence of menses for 6 months constitutes amenorrhea, but the basis for this recommendation is unclear. For a post-menarchal girl or a reproductive-aged woman to experience a menstrual cycle interval of more than 90 days is statistically unusual. Practically speaking, this should be an indication for an evaluation to seek the cause.
