- ItemRestrictedA modified exercise for combined reduction mammoplasty and breast conservation therapy in the treatment of breast cancer(2007) Hudson, Donald AWide local excision combined with postoperative radiotherapy is a useful technique for patients with breast cancer. For patients with macromastia whose tumor is situated in the lower pole of the breast, a breast reduction (keyholeinverted T pattern ) can be used to achieve wide local excision. However, for patients whose tumor is not in the inferior portion of the breast, and in whom this cancer also is situated close to the skin (requiring excision of skin with a 1-cm margin for oncologic safety), the traditional keyhole pattern cannot be used. A modification of the keyhole patterninverted T is described. The pedicle used depends on the site of the tumor. Although the breast scars are in different positions, a similar breast shape as well as symmetry still can be achieved. This is a useful technique for a select subgroup of patients. The outcomes for three patients are presented.
- ItemRestrictedThe flaws of laser Doppler in negative-pressure wound therapy research(2014) Kairinos, Nicolas; McKune, Andrew; Solomons, Michael; Hudson, Donald A; Kahn, DelawirRecent studies, using modalities other than laser Doppler, have indicated that perfusion during negative-pressure wound therapy (NPWT) is reduced, contrary to world literature. The aim of the present study was to evaluate whether the measuring technique of the laser Doppler could be influenced by the compressive nature of NPWT dressings and whether this could explain the conflicting findings. A hypothesis that it may be possible for laser Doppler to record similar readings to those obtained during NPWT by merely compressing tissues manually was tested on 12 NPWT dressings, with each undergoing an alternating series of manual compressive forces and NPWT (−125 mmHg). During the periods of NPWT (n = 12), the mean perfusion recording increased in five experiments, reduced in six, and remained unchanged in one. During the period when manual pressure was applied (n = 12), there was a mean increase in perfusion in six experiments and a reduction in six. The type of change in perfusion (increase or decrease) was the same for both NPWT and manual pressure in 10 of the 12 experiments. In conclusion, laser Doppler can incorrectly record increased perfusion when tissues are compressed, implying that it is flawed in the field of NPWT research as tissues are always compressed to some degree by the NPWT dressing.
