Diagnosing rhinitis: allergic vs. nonallergic.

Allergic rhinitis, the most common type of rhinitis, generally can be differentiated from the numerous types of nonallergic rhinitis through a thorough history and physical examination. Allergic rhinitis may be seasonal, perennial, or occupational. The most common cause of nonallergic rhinitis is acute viral infection. Other types of nonallergic rhinitis include vasomotor, hormonal, drug-induced, structural, and occupational (irritant) rhinitis, as well as rhinitis medicamentosa and nonallergic rhinitis with eosinophilia syndrome. Since 1998, three large expert panels have made recommendations for the diagnosis of allergic and nonallergic rhinitis. Allergy testing (e.g., percutaneous skin testing, radioallergosorbent testing) is not necessary in all patients but may be useful in ambiguous or complicated cases.

Acute shoulder injuries.

The shoulder is the most mobile joint in the human body. The cost of such versatility is an increased risk of injury. It is important that family physicians understand the anatomy of the shoulder, mechanisms of injury, typical physical and radiologic findings, approach to management of injuries, and indications for referral. Clavicle fractures are among the most common acute shoulder injuries, and more than 80 percent of them can be managed conservatively. Humeral head fractures are less common and usually occur in elderly persons; 85 percent of them can be managed nonoperatively. Common acute soft tissue injuries include shoulder dislocations, rotator cuff tears, and acromioclavicular sprains. Acromioclavicular injuries are graded from types I to VI. Types I and II are treated conservatively, types IV to VI are treated surgically, and there is debate about the best approach for type III. Eighty percent of shoulder dislocations are anterior. Diagnosis of this injury is straightforward. The injury usually can be reduced by employing a number of nonsurgical techniques. Traumatic or acute rotator cuff tears can be managed conservatively or surgically, depending on the patient and the degree of injury.
