Case Report of Proliferative Peripheral Retinopathy in Two Familial Lissencephaly Infants with Miller-Dieker Syndrome.

A complete ophthalmic examination is not routinely performed on infants with Miller-Dieker syndrome (MDS, chromosome 17p13.3 microdeletion). The authors present the cases of four cousins with MDS who also carried a 16p13.

Treatment-related MDS/AML in a patient after treatment for large-cell neuroendocrine lung cancer.

Secondary leukemia is a common late complication after exposure to cancer therapies such as chemotherapy and radiotherapy. With the increase in the overall survival of cancer patients over the past 3 decades, treatment-related malignant neoplasms have increased in incidence. Secondary leukemias due to breast cancer and Hodgkin lymphoma have been studied in detail, but to our knowledge only a few case studies have reported secondary leukemias with previous lung cancer.

Venous endothelial injury in central nervous system diseases.

The role of the venous system in the pathogenesis of inflammatory neurological/neurodegenerative diseases remains largely unknown and underinvestigated. Aside from cerebral venous infarcts, thromboembolic events, and cerebrovascular bleeding, several inflammatory central nervous system (CNS) diseases, such as multiple sclerosis (MS), acute disseminated encephalomyelitis (ADEM), and optic neuritis, appear to be associated with venous vascular dysfunction, and the neuropathologic hallmark of these diseases is a perivenous, rather than arterial, lesion. Such findings raise fundamental questions about the nature of these diseases, such as the reasons why their pathognomonic lesions do not develop around the arteries and what exactly are the roles of cerebral venous inflammation in their pathogenesis.

Association between fine particulate matter and oxidative DNA damage may be modified in individuals with hypertension.

Objective: To investigate the association between particulate matter (PM2.5) and urinary 8-hydroxy-2'-deoxyguanosine (8-OHdG) in hypertensive and non-hypertensive individuals.

Methods: Twelve hypertensives and nine non-hypertensives were monitored during a 36-hour period using a repeated-measures panel study design.

Protective effects of 17beta-estradiol and trivalent chromium on interleukin-6 secretion, oxidative stress, and adhesion of monocytes: relevance to heart disease in postmenopausal women.

Postmenopausal diabetic women are at greater risk for heart disease compared with men of similar age and with other risk factors. We examined the hypothesis that 17beta-estradiol and trivalent chromium inhibit secretion of the pro-inflammatory cytokine interleukin (IL)-6 and oxidative stress in monocytes exposed to high glucose (HG). U937 human monocytes were cultured with HG (30 mM) with and without 17beta-estradiol (0-1000 nM) and chromium chloride (Cr(3+), 0-10 muM) at 37 degrees C for 24 h.
