Orbital Exenteration for Eyelid Skin Carcinoma
Exenteration of the orbit is a disfiguring and destructive procedure; it is generally performed for orbital malignancies and often provides a significant reconstructive
challenge. Our purpose was to evaluate the clinical indications for orbital exenteration in a tertiary referral
center and to assess the reconstructive options employed. A retrospective nonrandomized analysis was performed,
selecting all patients undergoing orbital exenteration over a 5-year period, between January 2005 and January 2010.
Patient demographics, tumor characteristics, and reconstructive techniques used were evaluated. Twenty patients with a mean age of 76.5 years underwent total orbital
exenteration. Basal cell carcinoma was the main operative indication (45%), followed by squamous cell carcinoma (15%). Reconstructive techniques included cover of the raw orbital cavity with a temporal muscular flap in all cases followed with split skin grafting (25%), bilaterally pedicle V-Y advancement flap (10%) and a fasciocutaneous island flap of the retroauricular region (65%). Twenty percent of patients had local complications and all were treated in a satisfactory fashion. Eyelid skin tumors remain an important
cause of orbital exenteration. Temporal muscle flap is a reliable and stable reconstructive solution after orbital
exenteration and additional aid is supplied with skin grafts or local flaps. This technique ensures a good aesthetic
outcome and better situation for later complementary treatments and minimal associated donor site morbidity

Evaluation of the fertilizer potential of Chlorella vulgaris and Scenedesmus obliquus grown in agricultural drainage water from maize fields
Producing microalgae with agricultural drainage water (ADW) allows recycling water and nutrients, with the produc-
tion of a biofertilizer, avoiding receiving waters' contamination. Chlorella vulgaris and Scenedesmus obliquus were culti-
vated using ADW and standard media supplementation and presented higher productivities, relatively to the control
industrial growth medium (using freshwater). Selected strains were grown outdoors in pilot flat panel
photobioreactors, reaching 2.20 g L−1 for S. obliquus and 1.15 g L−1 for C. vulgaris, and degrading herbicides in the
ADW to non-quantifiable concentrations. The potential of the C. vulgaris and S. obliquus suspensions to replace 50%
of nitrogen (N) mineral fertilization of lettuce (0.5 g pot−1) was evaluated through a pot trial, also using a 2-times
(1.0 g pot−1) and 5-times (2.5 g pot−1) higher dose, applied 31 days before lettuce transplanting. Even the lower
dose of N, applied via C. vulgaris or S. obliquus suspensions, was able to provide significantly higher lettuce fresh matter
yield, relatively to the mineral fertilized control. Soil enzymatic activities were improved, with significantly higher de-
hydrogenase, β-glucosidase, and acid phosphatase activities for the 2.5 g pot−1 dose, more marked for S. obliquus,
which was also able to increase soil organic matter content. Both the non-fertilized control and microalgae fertilized
pots led to similar soil electrical conductivities, 3-fold lower than in the N-mineral fertilized pots, evidencing the capac-
ity of microalgae fertilizers to avoid soil secondary salinization. Results suggest benefits from using ADW from maize
cultivation to produce C. vulgaris or S. obliquus suspensions, that can be further used as liquid organic slow-release
