Priapism. Etiology, diagnosis and treatment

Priapism is a condition of prolonged penile erection which often causes pain and is unrelated to sexual desire. There is a high risk of impotence despite immediate intervention. The incidence has doubled since the introduction of intracorporeal injection therapy for impotence. Two subtypes of priapism have been described, depending on the underlying cause. The more common type, termed low flow, is characterised by inadequate venous outflow, leading to a hypoxic painful prolonged erection. The etiology is either idiopathic or related to intracorporeal injection therapy. Treatment consists of aspiration and instillation of a diluted alpha-adrenergic agent, or surgery, depending on the degree of hypoxia. The less common subtype, high flow, is arteriogenic, and causes less pain and no ischemia. Injury to a cavernous artery leads to a fistula between the artery and the corpora cavernosa. Treatment is either conservative with immediate ice pack and compression, or delayed selective embolization of the fistula.     

Acute otitis. Etiology, diagnosis, treatment

Glutaraldehyde is an antibacterial and antiviral agent commonly used for cleaning and disinfection of endoscopic equipment. The accepted glutaraldehyde air-concentration is 0.2 ppm. The irritant action, allergic potential and possible neurotoxicity of glutaral have been reported. Red eyes, cough, headache and running nose are most frequent symptoms of glutaral activity. The incidence of bronchial asthma and contact dermatitis has also been reported. In order to avoid occupational hazards of glutaraldehyde closed washing-disinfection systems, proper ventilation (20 cycles per hour), vapour recovery safety nozzle and neutralizing agent should be used.     

Chronic non-allergic rhinitis. Etiology, diagnosis and treatment

Chronic rhinitis can be defined as an inflammation of the nasal mucosa lasting for more than three months. The condition may be due to allergy or infection, or to a number of non-allergic and non-infectious causes, such as trauma, hormonal imbalance, toxic influence or locally applied drugs. The etiology, diagnostic procedures and treatment of non-allergic chronic rhinitis are discussed.
