Foot ulcers are a significant complication of diabetes mellitus and often precede lower-extremity amputation. The most frequent underlying etiologies are neuropathy, trauma, deformity, high plantar pressures, and peripheral arterial disease. Thorough and systematic evaluation and categorization of foot ulcers help guide appropriate treatment. ⋯ Prompt and aggressive treatment of diabetic foot ulcers can often prevent exacerbation of the problem and eliminate the potential for amputation. The aim of therapy should be early intervention to allow prompt healing of the lesion and prevent recurrence once it is healed. Multidisciplinary management programs that focus on prevention, education, regular foot examinations, aggressive intervention, and optimal use of therapeutic footwear have demonstrated significant reductions in the incidence of lower-extremity amputations.

ReviewEvaluation and management of herpes zoster ophthalmicus.
Herpes zoster ophthalmicus occurs when the varicella-zoster virus is reactivated in the ophthalmic division of the trigeminal nerve. Herpes zoster ophthalmicus represents up to one fourth of all cases of herpes zoster. Most patients with herpes zoster ophthalmicus present with a periorbital vesicular rash distributed according to the affected dermatome. ⋯ Permanent sequelae of ophthalmic zoster infection may include chronic ocular inflammation, loss of vision, and debilitating pain. Antiviral medications such as acyclovir, valacyclovir, and famcidovir remain the mainstay of therapy and are most effective in preventing ocular involvement when begun within 72 hours after the onset of the rash. Timely diagnosis and management of herpes zoster ophthalmicus. with referral to an ophthalmologist when ophthalmic involvement is present, are critical in limiting visual morbidity.

What to do when SSRIs fail: eight strategies for optimizing treatment of panic disorder.
Selective serotonin reuptake inhibitors (SSRIs) are the drug of choice for treatment of patients with panic disorder. Most patients have a favorable response to SSRI therapy; however, 30 percent will not be able to tolerate these drugs or will have an unfavorable or incomplete response. Strategies to improve management of such patients include optimizing SSRI dosing (starting at a low dose and slowly increasing the dose to reach the target dose) and ensuring an adequate trial before switching to a different drug. ⋯ All patients should be encouraged to try cognitive behavior therapy. Augmentation therapy should be considered in patients who do not have a complete response. Drugs to consider for use in augmentation therapy include benzodiazepines, buspirone, beta blockers, tricyclic antidepressants, and valproate sodium.

Epilepsy in women raises special reproductive and general health concerns. Seizure frequency and severity may change at puberty, over the menstrual cycle, with pregnancy, and at menopause. Estrogen is known to increase the risk of seizures, while progesterone has an inhibitory effect. ⋯ Children who are born to women with epilepsy are at greater risk of birth defects, in part related to maternal use of antiepileptic drugs. This risk is reduced by using a single antiepileptic drug at the lowest effective dose and by providing preconceptional folic acid supplementation. Breastfeeding is generally thought to be safe for women using antiepileptic medications.
