Preparation and bioevaluation of 99mTc-carbonyl complex of 5-hydroxy tryptamine derivative.

Studies on the development of imaging agents for targeting neuroreceptors is an area of considerable interest owing to the limited availability of specific as well as selective radiolabeled agents. Therefore, with an aim of developing a receptor-specific agent, iminodiacetic acid (IDA) derivative of 5-hydroxy tryptamine viz., HTIDA has been synthesized. HTIDA could be radiolabeled with the synthon [(99m)Tc(CO)(3)(H(2)O)(3)](+) in >98% yield. The biodistribution studies in normal Swiss mice showed that the (99m)Tc(CO)(3)-HTIDA crosses the blood-brain barrier successfully with a brain uptake of 0.5%ID/g at 5min post injection. The other relevant observations from biodistribution studies included no significant uptake in any other organ and fast clearance from blood, lungs and liver.     

Extended spectrum beta lactamase-producing Klebsiella pneumoniae infections: a review of the literature.

Infections caused by extended-spectrum beta-lactamase (ESBL)-producing pathogens, particularly Klebsiella pneumoniae, are increasing. The epidemiology of ESBL-producing K. pneumoniae, the mechanisms of resistance, and treatment strategies for infections caused by these organisms are reviewed.     

Clastogenic effect of fenfluramine in mice bone marrow cells in vivo

Fenfluramine, an amphetamine derivative used in the treatment of obesity, has been evaluated in vivo in the bone marrow cells of Swiss albino mice using two cytogenetic endpoints for assessing its genotoxic and clastogenic potentials. Concentrations of 0.75, 1.5, 3.0, and 5.0 mg/kg b.w. were administered orally for the study of sister chromatid exchange frequencies and chromosome aberrations (CA). SCE frequencies showed a positive dose response; 1.5 mg/kg being the minimum effective concentration. Fen caused a prolongation of cell cycle at all concentrations. Except for the minimum therapeutic dose (0.75 mg), all other doses (1.5, 3.0, and 5.0 mg) showed a significant increase in the percentage of damaged cells over that of the vehicle control. The degree of clastogenicity was directly proportional to the dosage used and inversely related with the duration of treatment. A gradual reduction of the clastogenic potential was observed after 12 and 24 hr of exposure, indicating that the maximum effect occurs at the middle or late synthetic phase of the cell cycle. This study, probably the first detailed screening of the drug for its genotoxicity, shows that Fen is moderately clastogenic and a DNA damaging agent in vivo.     

A case of Sturge-Weber syndrome in association with phacomatosis pigmentovascularis and developmental glaucoma.

Sturge-Weber syndrome is a rare neurocutaneous disorder characterized by a facial nevus flammeus and extensive angiomatous changes involving the leptomeninges, the dura, and vessels of the gray and white matter. Oculodermal melanocytosis is characterized by hyperpigmentation of the facial skin in the distribution of the ophthalmic, maxillary, and occasionally mandibular division of the trigeminal nerve.     

Domestic Violence Research: Methodological Issues Related to a Community‐Based Intervention With a Vulnerable Population1

Presently, in our society, thousands of children, adolescents, and adults are physically, mentally, and emotionally traumatized from exposure to domestic violence (DV). Exposure to DV, defined here as male violence against their female partners, occurs among all ethnic, cultural, socioeconomic, geographical, and racial groups. DV can lead to depression, negative self‐esteem, and general psychological distress in women. Children exposed to DV have an increased risk of behavioral, emotional, and social problems. DV shelters often provide group counseling and support services for battered women, children, and adolescents residing there, but the programs do not reach the majority of women living in the broader community. Furthermore, few studies have examined the effectiveness and efficacy of support group treatment intervention programs for battered women and children. This is due, in part, to the methodological difficulties inherent in this design. As a way to meet the needs of families that have experienced DV, academic researchers from a Midwestern university and a director of counseling services from a local domestic violence agency have partnered to offer a psycho‐educational intervention designed to     

Aeromonas hydrophila and aspiration pneumonia: a diverse presentation

Although there are ever increasing reports of extraintestinal human infections caused by Aeromonads, in both immunocompromised and immunocompetent patients, respiratory tract infections remain uncommon. We describe a case of aspiration pneumonia in an immunocompetent patient with multiple sclerosis, caused by a community acquired, multidrug resistant strain of Aeromonas hydrophila sensitive only to meropenem. The case highlights the clinical significance of Aeromonas hydrophila as a respiratory pathogen, as well as the community origin of multidrug resistance and the utility of newer carbapenems in such cases.
