Selectivity of executive function deficits in mild cognitive impairment.

Impairment in executive cognition (EC) is now recognized as relatively common among older persons with mild cognitive impairment (MCI) and may be predictive of the development of dementia. However, both MCI and executive functioning are broad and heterogeneous constructs. The present study sought to determine whether impairments in specific domains of EC are associated with specific subtypes of MCI.

Metastatic HPV-related cervical adenocarcinomas presenting with thromboembolic events (Trousseau Syndrome): clinicopathologic characteristics of 2 cases.

Two cases of systemic thromboembolism (Trousseau syndrome) associated with metastatic human papillomavirus (HPV)-related endocervical adenocarcinomas are reported. The first patient, age 36, presented with bilateral lower extremity deep vein thromboses, pulmonary embolism, and supraclavicular and cervical lymphadenopathy. Lymph node biopsy revealed metastatic mucinous adenocarcinoma with focal signet ring cell differentiation.

High-dose methotrexate in small cell lung cancer. Lack of efficacy in preventing CNS relapse.

Few studies have incorporated high-dose methotrexate (MTX) with leucovorin rescue in the treatment of small cell lung cancer (SCLC). Potentially therapeutic levels of MTX can be achieved in the central nervous system (CNS) by systemic administration of high doses of this drug. Utilizing a combination chemotherapy program of Adriamycin, vincristine, cyclophosphamide, and methotrexate, 31 patients were sequentially assigned to receive either low-dose MTX (40 mg/m2), or high-dose MTX (500 mg/m2) with leucovorin rescue.
