“…The most common are rotation, Z‐plasty, advancement, transposition, and interpolation. Making an S‐shaped skin incision to change the shape of the scar is not rare in operations in which a linear incision can be made 1–3 . The lazy‐S is an incision type for which the scar is effectively lengthened and the linear distance between the two constant points is conserved.…”

“…The lazy‐S is an incision type for which the scar is effectively lengthened and the linear distance between the two constant points is conserved. The primary repair of skin defects in which the final scar design is S‐shaped is known as an S‐plasty and can be classified as a variation of fusiform skin excision 2–5 . This technique is based on the conversion of the directions of the skin tension vectors using incisions that include maximal convexity to remove dog ears and to obtain a more aesthetically pleasing outcome.…”

“…This technique is based on the conversion of the directions of the skin tension vectors using incisions that include maximal convexity to remove dog ears and to obtain a more aesthetically pleasing outcome. Several advantages, including a decrease in the suture line tension and thus a decrease in factors such as tension that interfere with wound healing, a decrease in the risk of central scar depression, and a positive gain in aesthetic outcomes, have been reported for surgical procedures with an S‐shaped scar 1–4 …”

“…The final scar is Z‐shaped after Z‐plasty (Limberg flap), semi‐lunar after a rotation flap, and rectangular after transposition and interpolation flaps. Although an S‐shaped incision is preferred because of the S‐shaped scar, in many surgical procedures, 1–4 the repair of a defect with a technique that results in an S‐shaped scar has not yet been discussed. This article describes a local skin closure technique that we have named the S‐flap.…”

“…For example, mecadox (carbadox) I [2], methylnitrone II [3], and its analogues [4] are highly effective antibacterial and growth promoting agents. In addition to the above quinoxalines, quinacilline III [5], caroverine IV [6], and other quinoxalines [7][8][9] possess antibacterial activity.…”

A new series of potential antibacterial agents having tricyclic 1, 2, 4‐triazolo‐[4, 3‐a] quinoxaline fused with one or more heterocyclic rings was synthesized via several routes. The tricyclic 1‐amino‐4‐chloro‐1, 2, 4‐triazolo[4, 3‐a] quinoxaline (2 ) and tetracyclic 1, 6‐diamino‐bis‐1, 2, 4‐triazolo[4, 3‐a:3, 4‐c] quinoxaline (3) were synthesized from 2, 3‐dichloroquinoxaline (1) with two or four equivalents of thiosemicarbazide, respectively. Compound 2 was allowed to react with different aldehydes, alkoxides, cyclic amines, phenyl isothiocyanate, and t‐butyl isocyanate to afford the corresponding quinoxaline derivatives. Moreover, compound 2 reactedwithhydrazine hydrate to give compound 4 which was cyclized by carbondisulfide inalcoholic potassium hydroxide to give the tetracyclic compound 5 . Compound 2 was subjected to another cyclocondensation reaction using diethyl ethoxymethylene malonate (DEMM), dimethyl acetylenedicarboxylate (DMAD), and ethyl cyanoacetate to give the tetracyclic compounds 18 , 20 , and 21, respectively. All the synthesized compounds were evaluated in vitro for antibacterial activity; compounds 18 and 20 were found to display the greatest antibacterial activities. Structural identification was provided by elemental analyses, IR, and 1H‐NMR spectroscopy.

Background In staged excision procedures, it is difficult to estimate the number of excisions that will be required and the extent of scar lengthening. The purpose of this study was to investigate the effects of the size, shape, and resection amount of lesions on the outcomes of staged excision through an animal experiment. Methods In total, 20 ellipses with five different designs (n=4) were evaluated on pig skin. The experiment consisted of two groups: group 1 had excisions of the same length, but with different widths, while group 2 had excisions of the same size, but with different amounts of resection. The size of the lesions and the amount of resection were analyzed in terms of the ratio of length (long axis) and width (short axis) (S/L ratio). Results In the first group, initial ellipses measuring 5×4, 5×3, and 5×2 cm increased in size to 9.25±0.07 (185%), 8.55±0.07 (171%), and 8.10±0.14 cm (162%), respectively. In the second group, in which all ellipses measured 5×3 cm, those with a resection amount of 5×1.5, 5×2, and 5×2 cm with a fish fin grew to 8.75±0.15 (175%), 8.55±0.07 (171%), and 8.60±0.17 cm (172%), respectively. In group 1, the larger the S/L ratio, the longer the final length. In group 2, a greater resection amount was associated with a shorter final length. Conclusions We believe that the measurements of this study in terms of shape, size, and excision amount will be reasonable predictive references for staged excision procedures.
