Preventive Chemotherapy and Transmission Control (PCT) databank: a tool for planning, implementation and monitoring of integrated preventive chemotherapy for control of neglected tropical diseases.

The integration of vertical control programmes of neglected tropical diseases (NTDs) aims to contain operational cost, simplify the application of the control measures and further extend the coverage of interventions. The Preventive Chemotherapy and Transmission Control (PCT) databank was established by the WHO to facilitate access and sharing of information from national programmes with stakeholders involved in NTD control. The PCT databank contains compilations of historical and current information on disease-specific epidemiological situations, the geographical overlapping of NTDs and progress of control activities in all the NTD-endemic countries.

Prospective, multicenter demographic and epidemiological study on vernal keratoconjunctivitis: a glimpse of ocular surface in Italian population.

Purpose: To evaluate the frequency and epidemiological features of vernal keratoconjunctivitis (VKC) in Italy.

Methods: a specific electronic clinical chart for vernal keratoconjunctivitis was created to standardize: 1) medical history; 2) diagnostic criteria; 3) signs and symptoms; and 4) treatments. This study involved 6 Italian referral centers for ocular surface diseases: between March 2005 and March 2006, all referred patients were included, clinical data collected and statistically examined.

Human idiopathic epiretinal membranes express NGF and NGF receptors.

Purpose: Glial cells and fibroblasts (FBs) play a key role in epiretinal membrane (ERM) development and progression. Myofibroblasts (myoFBs), arising from these cells, can lead to the hypertrophic scars and tissue contraction observed in ERMs. Nerve growth factor (NGF) and transforming growth factor-beta1 (TGF-beta1) play a crucial role in FB activities.
