Penile Fracture
Penile Fracture samer kareem 4,454 Visualizações • 2 anos atrás

Traumatic penile injury can be due to multiple factors. Penile fracture, penile amputation, penetrating penile injuries, and penile soft tissue injuries are considered urologic emergencies and typically require surgical intervention. The goals of treatment for penile trauma are universal: preservation of penile length, erectile function, and maintenance of the ability to void while standing. Traumatic injury to the penis may concomitantly involve the urethra.[1, 2] Urethral injury and repair is beyond the scope of this article but details can be found in Urethral Trauma. Penile fracture Penile fracture is the traumatic rupture of the corpus cavernosum. Traumatic rupture of the penis is relatively uncommon and is considered a urologic emergency.[3] Sudden blunt trauma or abrupt lateral bending of the penis in an erect state can break the markedly thinned and stiff tunica albuginea, resulting in a fractured penis. One or both corpora may be involved, and concomitant injury to the penile urethra may occur. Urethral trauma is more common when both corpora cavernosa are injured.[4] Penile rupture can usually be diagnosed based solely on history and physical examination findings; however, in equivocal cases, diagnostic cavernosography or MRI should be performed. Concomitant urethral injury must be considered; therefore, preoperative retrograde urethrographic studies should generally be performed. See the images below.

The differential diagnosis of chest pain
The differential diagnosis of chest pain samer kareem 4,445 Visualizações • 2 anos atrás

Chest pain is a frequent complaint of patients seeking urgent medical assistance, and accounts for an estimated 2-4 per cent of all A&E visits in the UK (Becker, 2000). Generally, acute chest pain should be considered cardiovascular in origin until proven otherwise and it is common in clinical practice to err on the conservative or ‘safe’ side when evaluating people with chest pain. Individuals with suspected ischaemic chest pain must be evaluated rapidly for several reasons: - Myocardial ischaemia, if prolonged and severe, can cause myocardial infarction (necrosis); - Treatment strategies that achieve myocardial salvage (thrombolytic therapy or primary coronary angioplasty) are available for patients with acute coronary syndromes and these treatments reduce morbidity and mortality;

What is Anemia?
What is Anemia? samer kareem 4,440 Visualizações • 2 anos atrás

Anemia is a medical condition in which the red blood cell count or hemoglobin is less than normal. The normal level of hemoglobin is generally different in males and females. For men, a normal hemoglobin level is typically defined as a level of more than 13.5 gram/100 ml, and in women as hemoglobin of more than 12.0 gram/100 ml. These definitions may vary slightly depending on the source and the laboratory reference used. Continue Reading

Treatment For Epileptic
Treatment For Epileptic samer kareem 4,437 Visualizações • 2 anos atrás

The majority of epileptic seizures are controlled by medication, particularly anticonvulsant drugs. The type of treatment prescribed will depend on several factors, including the frequency and severity of the seizures and the person's age, overall health, and medical history. An accurate diagnosis of the type of epilepsy is also critical to choosing the best treatment. Drug Therapy Many drugs are available to treat epilepsy. Although generic drugs are safely used for most medications, anticonvulsants are one category where doctors proceed with caution. Most doctors prefer to use brand-name anticonvulsants, but realize that many insurance companies will not cover the cost. As a result, it is acceptable to start taking a generic anticonvulsant medication, but if the desired control is not achieved, the patient should be switched to the brand-name drug.

Genetic Disorders And Diseases
Genetic Disorders And Diseases samer kareem 4,428 Visualizações • 2 anos atrás

Genes are the building blocks of heredity. They are passed from parent to child. They hold DNA, the instructions for making proteins. Proteins do most of the work in cells. They move molecules from one place to another, build structures, break down toxins, and do many other maintenance jobs. Sometimes there is a mutation, a change in a gene or genes. The mutation changes the gene's instructions for making a protein, so the protein does not work properly or is missing entirely. This can cause a medical condition called a genetic disorder. You can inherit a gene mutation from one or both parents. A mutation can also happen during your lifetime.

Tension Pneumothorax
Tension Pneumothorax samer kareem 4,422 Visualizações • 2 anos atrás

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.
