The shifting paradigm in the management of giant congenital melanocytic nevi: review and clinical applications.

Summary: Congenital melanocytic nevi remain a subject of controversy with respect to risk of malignant transformation and recommended management. Recent studies indicate a lower malignant risk (0.7 to 2.9 percent) than had previously been estimated. Surgery has not been proven to reduce malignant risk or improve quality of life, and may result in undesirable aesthetic and functional outcomes. In this article, the authors review key controversial issues in the management of congenital melanocytic nevi and re-evaluate indications for surgical treatment. An updated review of controversial topics in the management of congenital melanocytic nevi is presented, and clinical applications are demonstrated through clinical cases. Updates regarding the risks and outcomes of congenital melanocytic nevi patients open a renewed debate with respect to the indications for surgery as well as the extent of surgery that may be suitable. Treatment should be tailored to achieve optimal aesthetic results whereby complete nevus excision is not the goal. As such, nonsurgical management and incomplete nevus excision should be integrated as legitimate parts of any treatment algorithm.

Anatomic sites of origin of the suprascapular and lateral pectoral nerves within the brachial plexus.

Background: The goal of this study was to clarify the anatomical origins of the suprascapular and lateral pectoral nerves from the brachial plexus as an aid to surgical exploration. Methods: Both nerves were studied in 100 adult cadaver specimens. Topographic points of origin were described as distance from the bifurcation of the upper trunk or distance from the formation point of the lateral cord, using visual anatomical models. Results: The suprascapular nerve originated from (1) the posterior division of the upper trunk distal to the bifurcation of the upper trunk (61 specimens); (2) the point of upper trunk bifurcation (29 cases); (3) the upper trunk proximal to the bifurcation point (six cases); and (4) directly from the C5 root (four cases). The lateral pectoral nerve originated from (1) the anterior division of the upper trunk proximal to the point of lateral cord formation (88 cases); (2) the point of lateral cord formation (five cases); (3) the lateral cord distal to the lateral cord formation point (four cases); and (4) the anterior division of the middle trunk (three cases). Eighty-two cases had origins from both the anterior upper trunk and the anterior middle trunk. Conclusions: The suprascapular nerve most frequently originates from the posterior division of the upper trunk, and the lateral pectoral nerve from the anterior divisions of the upper and middle trunks. This information can be used to guide the surgeon in identifying the key landmarks of the supraclavicular brachial plexus at surgical exploration.

Botulinum toxin for the treatment of motor imbalance in obstetrical brachial plexus palsy.

Background: Residual muscle imbalance is a common problem affecting obstetrical brachial plexus palsy patients. The goal of this study was to examine the efficacy of botulinum toxin type A (Botox) in improving this muscle imbalance. Methods: The authors retrospectively reviewed obstetrical brachial plexus palsy patients treated with Botox for muscle imbalance as an isolated procedure. Outcomes were the change in Active Movement Scale scores from pre–Botox scores to scores at 1 month after Botox and 1 year after Botox. Results: Twenty-seven patients were included, 19 treated for shoulder imbalance and eight treated for elbow imbalance. Active Movement Scale scores (mean ± SD) for shoulder external rotation improved from 0.6 ± 1.0 before Botox to 2.6 ± 2.14 (p < 0.01) at 1 month after Botox, and declined to 1.3 ± 1.2 (p < 0.01) at 1 year after Botox. Scores for elbow flexion were 3.3 ± 2.1 before Botox, unchanged at 4.4 ± 1.8 (p = 0.07) 1 month after Botox, and improved to 5.8 ± 0.5 (p < 0.01) at 1 year after Botox. Scores for elbow supination were 2.9 ± 1.7 before Botox and 3.4 ± 1.5 (p = 0.2) at 1 month after Botox, and improved to 3.9 ± 2.0 (p < 0.01) at 1 year after Botox. Conclusions: Botox for shoulder movement imbalance produces improvement in external rotation that is not sufficiently sustained over time to be of clinical benefit. However, Botox for elbow movement imbalance produces a sustained and clinically useful improvement. CLINICAL QUESTION/LEVEL OF EVIDENCE: Therapeutic, IV.

Skin necrosis after self-administered intramuscular diclofenac

Intramuscular diclofenac is used extensively for pain relief in medical practice. Tissue necrosis is a rare but serious complication of intramuscular injections. The pathogenetic mechanism is still not completely understood. A case of tissue necrosis following self-administration of diclofenac inadvertently injected into an arterial perforator branch of the superficial femoral artery is reported, supporting a vascular pathogenesis.

Paravertebral turnover flaps for closure of large spinal defects following tethered cord repair.

Reconstruction of large congenital spinal defects remains a challenge. We present our experience in closure of difficult spinal defects following repair of tethered cord, using paravertebral fascial or myofascial turnover flaps. Between 1996 and 2005, 23 patients were operated using paravertebral turnover flaps for closure of large spinal defects associated with tethered cord. Fifteen (65%) patients had lipomyelomeningoceles. Eleven (48%) patients had sacral defects, 10 (43%) had lumbosacral defects, and 2 (9%) had lumbar defects. Fourteen (61%) patients underwent closure using fascial turnover flaps. Myofascial turnover flaps were used in 9 (39%) patients. Following surgery, none of the patients developed cerebrospinal fluid (CSF) leaks, pseudomeningoceles, or subcutaneous infection. One patient suffered superficial necrosis and infection of the skin suture line, which healed secondarily. We conclude that fascial or myofascial paravertebral turnover flaps provide reliable coverage of difficult defects of the spinal CNS.

An Oncoplastic Breast Augmentation Technique for Immediate Partial Breast Reconstruction following Breast Conservation

Background: Patients with a small breast volume and a relative large lumpectomy volume are at risk of developing severe breast deformity and asymmetry following breast conservation, presenting a unique surgical challenge. Methods: A series of patients undergoing immediate reconstruction by means of an oncoplastic breast augmentation technique following breast conservation are described. The technique includes local tissue rearrangement and bilateral subpectoral breast augmentation with implants of different sizes and shapes, immediately after lumpectomy for a malignant tumor. Results: Twenty-one consecutive patients underwent the oncoplastic breast augmentation technique (mean follow-up, 23 months; range, 12 to 48 months). Three patients (14.3 percent) had tumor-positive surgical margins. Postoperative complications included grade III/IV capsular contracture in five patients (23.8 percent) and breast infection in two patients (10 percent). All patients received postoperative radiation therapy. The cosmetic outcome was evaluated at least 6 months after radiation therapy, and it was favorable according to the reported high patient satisfaction (81 percent) and independent observers’ evaluation scores (76 percent). Conclusions: The oncoplastic breast augmentation technique described in this article is an acceptable option in small-breasted patients with a relatively large lumpectomy volume who elect to undergo breast conservation. This technique allows conservation of the affected breast and minimizes potential breast deformation and asymmetry following radiation therapy. CLINICAL QUESTION/LEVEL OF EVIDENCE: Therapeutic, IV.

Body Builder’s Nightmare: Black Market Steroid Injection Gone Wrong: a Case Report

Summary: In the pursuit of success in sports, some athletes are not deterred by health risks associated with the (mis)use of black market preparations of dubious origin as performance-enhancing agents. Several studies published in the recent years demonstrated that anabolic-androgenic steroids, but also stimulants and growth hormones, are misused by numerous recreational athletes from all over the world. Trenbolone is an anabolic steroid routinely used in the finishing phase of beef production to improve animal performance and feed efficiency. A 35-year-old male patient presented to our plastic surgery clinic after self-intramuscular administration of Trenbolone to the superior gluteal area bilaterally, which led to a full-thickness defect in a cone-like distribution. The wounds underwent surgical debridement and were treated locally with mafenide acetate irrigation and wound dressings. Closure was achieved by secondary intention healing. In this report, we discuss the first documented case of full-thickness skin and subcutaneous tissue necrosis after black market anabolic steroid injection. This illustrates a plastic complication and resolution of a widespread but seldom reported problem.

Comprehensive approach in surgical reconstruction of facial nerve paralysis: a 10-year perspective.

Facial paralysis presents diverse functional and aesthetic abnormalities. Reconstruction may be achieved by several methods. We reviewed the management and outcome of facial paralysis patients to establish principles on which a comprehensive reconstructive approach may be based. Records were reviewed of all patients operated for facial paralysis at our institution between 1998 and 2007. Ninety-five patients were included, of which 15 patients had static reconstruction alone, and 80 patients had dynamic reconstruction. Presented is our experience in reconstruction of facial paralysis over the past decade, delineating a comprehensive approach to this condition. Various surgical techniques are described.

DIEP Flap Breast Reconstruction Complication Rate in Previously Irradiated Internal Mammary Nodes

Background Postmastectomy radiation therapy (PMRT) is a widely accepted treatment for locally advanced breast cancer. Some patients require additional boost radiation to the internal mammary nodes as the part of regional nodal irradiation (RNI). Delayed breast reconstruction with an autologous free flap using the internal mammary vessels for microvascular flap anastomosis is a common practice for these patients. The aim of our study was to evaluate the effect of RNI on autologous microvascular breast reconstruction. Patients and Methods A retrospective study was performed on 57 patients (69 flaps) undergoing deep inferior epigastric perforator (DIEP) flap for delayed breast reconstruction after radiation therapy. The study group included 37 patients (65%) who received PMRT and RNI to the internal mammary nodes. The control group included 20 patients (35%) who received PMRT alone. Early and delayed surgical complications, including wound complications, fat necrosis, and flap loss, were compared between the groups. Results The patient demographics in both groups were similar. Complication rate showed a higher trend in the study group for flap loss (8.3% versus 0%) and vascular anastomosis failure (5.6% versus 0%), but with no statistical difference (p = 0.54, 0.53, respectively). The control group showed a higher trend in fat necrosis (25% versus 8.3%, p = 0.11). Conclusions DIEP flap breast reconstructions with internal mammary vessels anastomosis should be performed with cautious in patients who had received RNI to internal mammary nodes because of potential added risk for surgical complications.

Pediatric burns in Israeli natives versus asylum seekers living in Israel: Lessons learned

BACKGROUND Burn injuries are one of the leading causes of morbidity and mortality in the pediatric population. In early childhood, burns have a wide range of adverse long-term consequences ranging from functional impairment to psychological implications. Children from low-income and middle-income countries are at a higher risk of suffering from burn injuries. In the last 10 years the population of asylum seekers from low-income countries in Israel has increased dramatically. About 25,000 or 60% of asylum seekers are living in the Tel Aviv area, making up roughly 6% of the citys total population (about 405,000). AIM A retrospective study aimed to profile the pediatric burn injuries treated at the Tel Aviv Sourasky Medical Center over the last 9 years in an effort to examine the distinct characteristics of African asylum seekers who suffer burn injuries in comparison with Israeli nationals. PATIENTS & METHODS Medical records of 876 patients under the age of 18 years presenting between 2007-2015 were retrospectively reviewed. The parameters collected included gender, causality, total body surface area (TBSA), burn depth and patient outcome. CONCLUSIONS There was no significant difference regarding: age; male-female ratio; scald-types burns; limb involvement. However, hospitalization and length of hospital stay were significantly higher among asylum seekers, as was family burden. Questions may be raised regarding prevention, education & social support. Our research provides a small glimpse into the world of asylum seekers in Israel. We hope it will serve as a window into the much grander problems that this population faces on a daily basis.
