Abstract Background The revolving door flap, although well described in the literature, is not widely used in general plastic surgery practice. The flap has been used for anterior auricular and conchal defects and is considered elegant for its unique flap design and peculiarity of flap harvest. However, due to its use for a very specific purpose and unique flap harvest technique that may be difficult to grasp, the flap is not very popular in reconstructive practice. Objectives This study aims to evaluate the understanding and learning curve of the revolving door flap, assess surgical outcome, and reemphasize its utility and elegance in reconstruction of ear defects. Methodology This is a case series of nine surgeries performed between January 2014 and 2018. Three cases were performed by the senior author and six cases by two junior authors. Patients were observed for complications and aesthetic outcomes. Results The mean dimension of the flaps was 27.22 mm × 22.78 mm. The mean operative time was 56.56 minutes (standard deviation 22.50, standard error of the mean 7.5). Flap congestion was noted in three cases postoperatively which resolved completely by the second week. Major “pinning” of the ear was noted in four cases. Conclusion Though infrequently performed, the revolving door flap has an easy learning curve once the proper harvest technique and flap movement has been grasped. The flap harvest is convenient, safe, and yields predictable results. Not only is total or partial flap loss extremely rare, the flap is sensate, color match is good, auricular contour is maintained, and the donor site can be closed primarily and remains well hidden.

Objective: To determine if suprafascial harvest of the radial forearm free flap improves postoperative donor site outcomes compared to subfascial harvest. Methods: Retrospective chart review. Results: Forty-six patients underwent reconstruction of a head and neck defect with a radial forearm free flap (RFFF). Subfascial harvest of the RFFF was performed in 25 (53%) patients and suprafascial harvest performed in 22 (47%) patients. All donor sites were covered with a split thickness skin graft and a bolster that remained in place for 6 days. Postoperative tendon exposure at the donor site occurred in 5 (20%) of the patients in the subfascial group and in 0 (0%) of the patients in the suprafascial group ( P = .05; Fisher’s exact test). Average tourniquet time was 117 minutes in the subfascial group and 102 minutes in the suprafascial group. Hematoma formation occurred at the donor site in 2 (8%) and 1 (5%) patients in the subfascial and suprafascial groups, respectively. There were no complete or partial flap losses in either group. Conclusions: Suprafascial harvest of the RFFF decreases the risk of postoperative tendon exposure. The suprafascial harvest technique does not increase harvest time or donor site complications, nor does it negatively impact flap vascularity.

Harvest Technique

Water, wind and tillage erosion are well-studied soil erosion processes. However, there is another process of soil erosion that is rarely considered in the field of earth sciences but one that should not be neglected when calculating soil denudation rates and sediment budgets, i.e., soil loss due to crop harvesting (SLCH). Loose soil and soil adhering to the crop and rock fragments are harvested and exported from the field along with crops such as sugar beet (Beta vulgaris L.), potato (Solanum tuberosum L.) and chicory (Cichorium intybus L.). In this paper several assessments of SLCH found in the literature are listed, revealing that soil loss due to crop harvesting may range from a few Mg up to a few tens of Mg per hectare per harvest. As most literature discussing this soil loss does not originate from the field of earth sciences, and terms used to describe this phenomenon are not standardized, a terminology is proposed to describe soil losses due to crop harvesting compatible with terms used in the field of soil erosion. Furthermore, the parameters determining SLCH are reviewed based on a detailed literature study that focuses mainly on sugar beet. These parameters may be grouped into four factors, i.e. soil, crop, agronomic practices and harvest technique. Variations in soil moisture and soil texture cause the largest variations in SLCH, although other factors, such as harvest technique, also play an important role. Given the importance of SLCH in terms of on-site and off-site effects, more research is needed to quantify SLCH under different environmental conditions.

Mushrooms are macrofungi that serve as a vegetarian source of protein along with various bio-active molecules of primary health importance. The activity of the bio-active molecules range from antioxidant, immunomodulation, hepatoprotection. Cultivated oyster mushrooms are also rich in these components which may be estimated quantitatively by skill intensive ‘destructive’ chemical techniques. Infra Red spectroscopy provides a non-destructive user friendly technique to quickly assess the presence of bio-active compounds in mushroom species to be used as a quality control measure as this non-destructive tool can be used to segregate mushroom harvest according to availability of bioactive compounds. IR spectra based strain classification and taxa delimitation of mushroom samples are also attempted vis a vis DNA sequence based phylogeny analysis of the same, but no correlation is observed between the two types of phylogeny analysis.

Aloe barbadensis (Aloe vera) plants remain in production fields for several years, with their lower leaves harvested periodically. A long-term experiment was initiated in November 1993 to determine the effects of fertilization and severeness of harvest on leaf yield. Plants were grown in large pots with or without monthly applications of a 20N–8.6P–16.6K soluble fertilizer from March to October. Beginning in June 1994, the lower leaves were harvested quarterly to have 18, 15, or 12 leaves remaining. Fertilization doubled the number of leaves harvested and tripled the total yield over a 2-year period. The lower leaves on the nonfertilized plants, particularly on plants with 18 leaves remaining, sometimes became dry or partially dry at harvest. The initial quarterly yield and cumulated yield were higher in plants with 12 leaves remaining; however, this trend disappeared over time. The fertilized plants produced an average of 10 kg per plant, while the nonfertilized plants produced only 3.2 kg per plant annually. At several harvests, plants with 18 leaves remaining had higher % dry mass in the inner semi-translucent tissue than those having 12 leaves. Leaves of nonfertilized plants had high % dry mass in the inner leaf tissue when harvested in June and September 1995. Plants with 12 leaves remaining can become unstable and the tops break off in gusty wind.
