New surgical approach in the management of pseudophakic malignant glaucoma

Purpose: To describe a new surgical approach in the management of pseudophakic malignant glaucoma. Design: Noncomparative case series. Participants: Five consecutive patients with pseudophakic malignant glaucoma. Methods: All patients underwent zonulo-hyaloido-vitrectomy. The procedure involves the performance of zonulectomy, hyaloidectomy, and anterior vitrectomy (zonulo-hyaloido-vitrectomy) through a peripheral iridectomy or iridotomy via the anterior chamber. Main Outcome Measures: Medications, visual acuity, intraocular pressure, and anterior and posterior segment findings were recorded before and after surgery. Results: Resolution of the malignant glaucoma was achieved in all cases. No recurrences were observed after a median follow-up of 5.5 months (range, 1-9 months). In one patient with extensive anterior synechiae, bleb failure occurred after the resolution of the malignant glaucoma. This patient was treated successfully with a guarded filtration procedure supplemented with 5-fluorouracil. No other complications were observed. Conclusions: Zonulo-hyaloido-vitrectomy via the anterior segment appears to be an alternative option in the treatment of patients with pseudophakic malignant glaucoma. © 2001 by the American Academy of Ophthalmology.

Working with fathers to improve children's well-being: Results of a survey exploring service provision and intervention approach in the UK

Interventions for fathers are a recent growth area in family services. Although some specific approaches are beginning to be evaluated, there is little known about what kinds of interventions are more generally being used in practice. A web-based survey of practitioners was conducted in the UK, with contact being made via local authority service managers. Two hundred and twenty-one responses were received from 53% of local authorities. Both interventions specifically for fathers and services for both parents were targeted in the survey. Results are reported on organisational location; targeting of services; type of intervention; numbers and percentages of men attending services, recruitment of fathers; evaluation strategies; and ideological and theoretical approaches. Numbers of fathers engaged are relatively low - e.g. the median annual number of fathers attending structured parenting courses was eight and in courses for both parents, 21% of those attending were men. Responses on ideological and theoretical approaches suggest that overt gender politics play only a small part, but that the dominant views of practitioners are in line with mainstream approaches to parenting support. Cognitive and behavioral approaches were the most popular.

Sphingosine Kinase 1 Promotes Malignant Progression in Colon Cancer and Independently Predicts Survival of Patients With Colon Cancer by Competing Risk Approach in South Asian Population

OBJECTIVES: Sphingosine kinase 1 (SphK1) phosphorylates the membrane sphingolipid, sphingosine, to sphingosine-1-phosphate (S1P), an oncogenic mediator, which drives tumor cell growth and survival. Although SphK1 has gained increasing prominence as an oncogenic determinant in several cancers, its potential as a therapeutic target in colon cancer remains uncertain. We investigated the clinical relevance of SphK1 expression in colon cancer as well as its inhibitory effects in vitro.

METHODS: SphK1 expression in human colon tumor tissues was determined by immunohistochemistry and its clinicopathological significance was ascertained in 303 colon cancer cases. The effects of SphK1 inhibition on colon cancer cell viability and the phosphoinositide 3-kinase (PI3K)/Akt cell survival pathway were investigated using a SphK1-selective inhibitor-compound 5c (5c). The cytotoxicity of a novel combination using SphK1 inhibition with the chemotherapeutic drug, 5-fluorouracil (5-FU), was also determined.

RESULTS: High SphK1 expression correlated with advanced tumor stages (AJCC classification). Using a competing risk analysis model to take into account disease recurrence, we found that SphK1 is a significant independent predictor for mortality in colon cancer patients. In vitro, the inhibition of SphK1 induced cell death in colon cancer cell lines and attenuated the serum-dependent PI3K/Akt signaling. Inhibition of SphK1 also enhanced the sensitivity of colon cancer cells to 5-FU.

CONCLUSION: Our findings highlight the impact of SphK1 in colon cancer progression and patient survival, and provide evidence supportive of further development in combination strategies that incorporate SphK1 inhibition with current chemotherapeutic agents to improve colon cancer outcomes.
