Summary: A new advanced technology, noncontact diffuse correlation spectroscopy, has been recently developed for the measurement of tissue blood flow through analyzing the motions of red blood cells in deep tissues. This technology is portable, inexpensive, and noninvasive, and can measure up to 1.5-cm tissue depth. In this prospective study, the authors aimed to explore the use of this novel device in the prediction of mastectomy skin flap necrosis. The noncontact diffuse correlation spectroscopy device was used to measure mastectomy skin flap flow in patients undergoing mastectomy and immediate implant-based breast reconstruction before and immediately after mastectomy, and after placement of the prosthesis. Patients were tracked for the development of complications, including skin necrosis and the need for further surgery. Nineteen patients were enrolled in the study. Four patients (21 percent) developed skin necrosis, one of which required additional surgery. The difference in relative blood flow levels immediately after mastectomy in patients with or without necrosis was statistically significant, with values of 0.27 ± 0.11 and 0.66 ± 0.22, respectively (p = 0.0005). Relative blood flow measurements immediately after mastectomy show a significant high accuracy in prediction of skin flap necrosis, with an area under the receiver operating characteristic curve of 0.95 (95 percent confidence interval, 0.81 to 1). The noncontact diffuse correlation spectroscopy device is a promising tool that provides objective information regarding mastectomy skin flap viability intraoperatively, allowing surgeons early identification of those compromised and ischemic flaps with the hope of potentially salvaging them. CLINICAL QUESTION/LEVEL OF EVIDENCE: Diagnostic, IV.

Dermal Regenerative Template as a Cost-Effective Alternative for Complex Scalp Reconstruction

Nneamaka Agochukwu; Lesley Wong; James Y. Liau

Background: Use of dermal regeneration template (DRT) is well documented in the literature for complex wounds ranging from the scalp, trunk, and lower extremity. Methods: A retrospective cohort study was performed of the use of dermal regeneration template and skin grafting. A literature review was performed of all studies where DRT was used for scalp reconstruction. Results: Patients in the DRT cohort had an average age of 70, with wounds averaging 108 cm2 in size. These patients also had a relatively low rate of complications (0.4), a short hospital stay (average 2 days), and a relatively short operating room time (114 minutes). Conclusion: This study demonstrates dermal regeneration template to be an effective and reliable option for soft tissue reconstruction with minimal morbidity and complications in patients with extensive medical comorbidities. Emerging applications include radiation exposure and hypercoaguable states.

Diabetic Mastopathy: A Systematic Review of Surgical Management of a Rare Breast Disease

Nneamaka Agochukwu; Lesley Wong

Abstract Diabetic mastopathy is a benign condition of the breast that typically manifests in patients with diabetes mellitus. Lymphocytic mastopathy is the term used to describe this condition in patients without diabetes mellitus. Most patients undergo excisional biopsy, but the use of mastectomy, even in cases of diffuse, bilateral disease, is rarely reported. We present a 32-year-old female patient with type 1 diabetes and bilateral diabetic mastopathy. Because of pain, and concern for limitations in future cancer detection, she underwent bilateral nipple-sparing mastectomies with immediate direct-to-implant reconstruction. A systematic literature review was performed to examine the treatment options for this disease, particularly from a plastic surgery perspective. Sixty articles were reviewed which contained information regarding 313 patients. Of these patients, only 4 underwent mastectomy. This case is the first report of bilateral nipple sparing mastectomy and immediate implant reconstruction for a patient with bilateral, symptomatic diabetic mastopathy.

Symptomatic Nonsyndromic Pancarpal Coalition: Report of a Rare Case and Review of the Literature

Nneamaka Agochukwu; Betty Yan; Daniel H. Stewart

Carpal coalition, the union of 2 or more carpal bones, can be congenital or acquired. Congenital, nonsyndromic carpal coalition usually presents in otherwise healthy individuals. The most common coalition is between the lunate and the triquetrum, followed by the capitate and the hamate. Pancarpal coalition, or coalition of all or most of the bones of the carpus, is an extremely rare finding and usually occurs as part of a syndrome. We present a nonsyndromic case of this rare entity, in a 28-year-old woman of West African descent, with symptoms of left hand and wrist pain. Our literature review revealed only 1 other reported case of isolated, nonsyndromic symptomatic pancarpal coalition.
