Review Case ReportsTreatment of extramammary Paget disease with topical imiquimod cream: case report and literature review.
Extramammary Paget disease is an uncommon cutaneous neoplasm that presents as erythematous plaques most frequently located in the anogenital region. Management of patients with extramammary Paget disease involves evaluation of the individual for: (1) a disease-associated, unsuspected, visceral malignancy and (2) secondary adenocarcinoma in the underlying dermis or regional lymph nodes. Several modalities, each with variable effectiveness, are available to treat the cutaneous component of the disease: electrodesiccation and curettage, laser surgery, aminolevulinic acid photodynamic therapy, radiotherapy, topical chemotherapy, and wide surgical excision. ⋯ Biopsy-confirmed complete resolution of his disease was observed after the topical application of imiquimod 5% cream 3 times per week (on alternate days) for 16 weeks. After reviewing the published reports of other patients with extramammary Paget disease whose disease was successfully treated with imiquimod cream, we suggest that topical imiquimod 5% cream-at least 3 times per week (with 1-2 d of nontreatment in between) for a minimum of 8 to 16 weeks--be considered as an initial treatment for primary cutaneous extramammary Paget disease. Surgical excision or an alternative therapeutic modality is recommended for patients whose extramammary Paget disease persists or recurs after treatment with topical imiquimod.

Dysnatremias are a common clinical entity that are often associated with poor outcomes. This review takes a case study approach to understand how dysnatremias can result in devastating neurologic consequences. ⋯ Reasons to avoid using hypotonic parenteral fluids, risk factors for hyponatremic encephalopathy such as age, gender, and hypoxia, and the appropriate use of 3% sodium chloride are discussed. Case studies in hypernatremia include hypernatremia in the ICU setting and the emerging condition of breastfeeding-associated hypernatremia in infants.

Case ReportsAn unrecognized cause of recurrent hypercalcemia: immobilization.
We report a 66-year-old Chinese man with chronic renal insufficiency (creatinine 1.7 mg/dL) and gout suffering from slurred speech and right hemiplegia for 3 days. Acute cerebral infarction was confirmed by computed tomography. Conscious disturbance occurred on the tenth hospital day without significant changes on imaging study when compared with a previous scan. ⋯ Hypercalcemia and renal failure were temporarily ameliorated after aggressive volume expansion and loop diuretic treatment but recurred 2 weeks later. Immobilization hypercalcemia was considered after the exclusion of other discernible causes and was successfully treated with rehabilitative exercises and bisphosphonates without further recurrence during a 2-year follow-up. Clinical alertness to immobilization as a possible cause of hypercalcemia may avoid unnecessary and invasive examinations, life-threatening complications and annoying recurrences.
