Hoarseness is a common presentation in primary care practices. Combined with other voice-related changes, it falls under the umbrella diagnosis of dysphonia. Hoarseness has a number of causes, ranging from simple inflammatory processes to less common psychiatric disorders to more serious systemic, neurologic, or cancerous conditions. ⋯ Patients who experience symptoms lasting longer than two weeks and who have risk factors for dysplasia (e.g., tobacco use, heavy alcohol use, hemoptysis) may require earlier laryngoscopic evaluation. Voice therapy is effective for improving voice quality in patients with dysphonia if conservative measures are unsuccessful, and it can also be helpful for prophylaxis in high-risk individuals (e.g., vocalists, public speakers). Surgical management is indicated for laryngeal or vocal fold dysplasia or malignancy, airway obstruction, or benign pathology resistant to conservative treatment.

Hyperosmolar hyperglycemic state is a life-threatening emergency manifested by marked elevation of blood glucose and hyperosmolarity with little or no ketosis. Although there are multiple precipitating causes, underlying infections are the most common. Other causes include certain medications, nonadherence to therapy, undiagnosed diabetes mellitus, substance abuse, and coexisting disease. ⋯ Once dehydration is partially corrected, adults should receive an initial bolus of 0.1 units of intravenous insulin per kg of body weight, followed by a continuous infusion of 0.1 units per kg per hour (or a continuous infusion of 0.14 units per kg per hour without an initial bolus) until the blood glucose level decreases below 300 mg per dL. In children and adolescents, dehydration should be corrected at a rate of no more than 3 mOsm per hour to avoid cerebral edema. Identification and treatment of underlying and precipitating causes are necessary.

ReviewHerpes Zoster and Postherpetic Neuralgia: Prevention and Management.
Herpes zoster, or shingles, is caused by reactivation of varicella zoster virus, which causes chickenpox. There are an estimated 1 million cases in the Unites States annually, with an individual lifetime risk of 30%. Patients with conditions that decrease cell-mediated immunity are 20 to 100 times more likely to develop herpes zoster. ⋯ Treatment is focused on symptom control and includes topical lidocaine or capsaicin and oral gabapentin, pregabalin, or tricyclic antidepressants. The varicella zoster virus vaccine decreases the incidence of herpes zoster and is approved for adults 50 years and older. The Centers for Disease Control and Prevention's Advisory Committee on Immunization Practices recommends this vaccine for adults 60 years and older, except for certain immunosuppressed patients.
