Abstract
BACKGROUND Implant-based breast reconstruction is one of the most common procedures among women with breast cancer undergoing mastectomy. Prosthetic devices may be positioned either beneath or above the pectoralis major muscle, which is considered an accessory muscle of ventilation. This preliminary prospective study aimed to investigate whether subpectoral unilateral implant-based breast reconstruction has any effect on patients' pulmonary functions. METHODS A prospective study of fourteen women who underwent immediate unilateral implant-based subpectoral breast reconstruction by a single surgeon over 10 months was conducted. Spirometry and maximal voluntary ventilation tests were conducted 1 day prior to surgery, and 1- and 3 months following breast reconstruction. ANOVA or Friedman test were used to compare pulmonary function tests before and after surgery. RESULTS Fourteen patients completed the study protocol. No statistically significant differences were found when comparing spirometry parameters in the three time points. CONCLUSIONS Pectoralis muscle release does not impair pulmonary function among patients undergoing immediate unilateral implant-based breast reconstruction following mastectomy.

Abstract
Postburned auricular keloids are a challenging problem for the patient and physician. We describe a successful combined treatment of a bulky postburn auricular keloid employing intralesional cryosurgery followed by multiple W-plasty. An EAR-Q pre- and postoperative patient-reported outcome assessments have revealed a significant improvement in all ear parameters of appearance, adverse effects, and quality of life. This combined treatment might be added to the armamentarium of possible treatment modalities for this perplexing problem.

Safety of troclosene sodium solution in decontamination of wounds: A prospective clinical and laboratory study. Wound Repair Regen 2023; 31:635-640. [PMID: 37358433 DOI: 10.1111/wrr.13105] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/21/2023] [Revised: 05/15/2023] [Accepted: 06/14/2023] [Indexed: 06/27/2023]
Abstract
Debate persists regarding the safety of hypochlorite-containing solutions in the decontamination of infected wounds. In 2006, the Israeli Ministry of Health withdrew licensing approval for troclosene sodium as a wound irrigation solution. The aim of this prospective clinical and laboratory study was to investigate the safety of troclosene sodium solution for decontamination of infected wounds. Troclosene sodium solution was used to treat 30 patients with 35 infected skin wounds of various etiologies and body areas, over a treatment period of 8 days. Data were gathered according to a prospectively designed protocol including general findings, wound-specific observations on Day 1 and Day 8 and laboratory parameters on Day 1 and Day 8. Wound swabs and tissue biopsy for culture were taken on Day 1 and Day 8. Statistical analysis was executed. Tests were 2-sided and p values of <0.05 were considered statistically significant. Eighteen males and 12 females, with 35 infected skin wounds were enrolled. There were no adverse clinical events. No significant changes were observed in general clinical observations. Statistically significant improvements were observed in: pain (p < 0.0001); edema (p < 0.0001); area of wound covered by granulation tissue (p < 0.0001); exudate (p < 0.0001); and erythema (p = 0.002). Prior to treatment, bacteria were demonstrated on microscopy or on culture in 90% of wound samples. On Day 8, this frequency reduced to 40%. There were no abnormal laboratory tests. Serum sodium concentration increased significantly between Day 1 and Day 8, whilst serum concentration of urea and concentrations of thrombocytes, leucocytes and neutrophils showed statistically significant reductions, but all values remained within normal laboratory ranges throughout the study period. Troclosene sodium solution is clinically safe in the management of infected wounds. These findings were presented to the Israel Ministry of Health and as a result, troclosene sodium was re-approved and licensed for decontamination of infected wounds in Israel.

Abstract
OBJECTIVE To identify risk factors associated with accidental fetal skin lacerations (AFL) during cesarean section (CS). METHODS This retrospective cohort study was obtained from the registry of two large medical centers between 2014 and 2019. The study group comprised all newborns identified with AFL. The rates of various potential risk factors were compared between the study group and a group of CS at which no AFL had occurred (the control group). RESULTS Of the 14 666 CS deliveries, 48 cases of AFL (0.33%) were documented, 52% of these following urgent CS. Compared with the control group (n = 14 618), the only risk factors associated with AFL were premature rupture of membranes (PROM) (odds ratio [OR] 5.38, 95% convidence interval [CI] 2.97-9.74) and meconium-stained amniotic fluid (OR 6.50, 95% CI 2.55-16.54). In subgroup analysis by CS urgency, no significance for these factors was noted in elective CS group; but higher rates of both PROM and meconium-stained amniotic fluid were noted in the AFL during urgent CS (OR 14.23, 95% CI 6.30-32.16 and OR 15.36, (95% CI 5.65-41.75, respectively). CONCLUSIONS During urgent CS, the surgeon should bear in mind that the presence of PROM or meconium-stained amniotic fluid should prompt extra care and application of preventive measures to decrease the rates of AFL.

Abstract
AbstractToday, plastic surgery is a well-known profession with highly respected surgeons from institutions all over the world. Over the last several decades numerous clinical and technological advances have been made, thanks to the dedication and hard work of these outstanding professionals; however, things were not always this way. At the turn of the 20th century, Israel had yet to be introduced to the field of plastic surgery. However, this all changed with the War of Independence. Humanitarian aid by the prominent South African surgeon, Jack Penn, laid the foundation for the founding fathers of plastic surgery in Israel to establish a strong legacy of producing world-renowned surgeons and innovators. Through this paper, we hope to provide a brief overview of the history of plastic surgery in Israel and what transpired to give us the state of surgical practice we have today.

Rapid, quantitative prediction of tumor invasiveness in non-melanoma skin cancers using mechanobiology-based assay. Biomech Model Mechanobiol 2021; 20:1767-1774. [PMID: 34120276 DOI: 10.1007/s10237-021-01475-z] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/19/2020] [Accepted: 06/04/2021] [Indexed: 11/29/2022]
Abstract
Non-melanoma skin cancers, including basal and squamous cell carcinomas (BCC and SCC), are the most common malignancies worldwide. BCC/SCC cancers are generally highly localized and can be surgically excised; however, invasive tumors may be fatal. Current diagnosis of skin cancer and prognosis of potential invasiveness are based mainly on clinical-pathological factors of the biopsied lesions. SCC invasiveness is also predicted by histomorphological factors, such as the degree of differentiation or the mitotic index, while BCCs are typically considered non-invasive. The above subjective measures do not provide direct, objective prognosis of cellular invasiveness in each specific sample. Hence, we have developed a mechanobiology-based approach to rapidly determine sample invasiveness. Here, cells from 15 fresh tissue samples of suspected non-melanoma skin cancer were seeded on physiological-stiffness (2.4 kPa) synthetic gels, and within 1-h invasive cell subsets were observed to push/indent the gel surface; clinicopathological results were separately obtained using standard protocols. The percentage of indenting cells from invasive (26.2 ± 2.4%) and non-invasive (4.8 ± 0.5%) SCC samples differed significantly (p < 0.0001), with well-separated invasiveness cutoffs of, respectively, > 12% and < 5%. The mechanical invasiveness directly agrees with the SCC cell-differentiation state, where over 3.3-fold more (p < 0.0001) cells from moderately differentiated samples indent the gels as compared to well-differentiated cell samples. In BCCs, < 20% of cells typically indented, and a highly migratory, desmoplastic sample was identified with 46%. By providing rapid, quantitative, early prognosis of invasiveness and potential metastatic risk, our rapid technology may facilitate informed (bed-side) decision making and choice of disease-management protocols on the time-scale of the initial diagnosis and surgical excision.

Abstract
BACKGROUND Auricular keloids belong to the most perplexing medical conditions, which have significant psychosocial impact on the patient's body image and quality of life. SUMMARY The article is purposed to provide dermatologists and plastic surgeons with the best proven practice using intralesional cryosurgery for the treatment of the different auricular keloid types in order to obtain superior clinical results by minimizing the probability of recurrence. In the past 20 years, the authors have developed novel procedures in order to increase the effectiveness of intralesional cryosurgery on auricular keloids, including hydrodissection, warm gauze technique, and excision of dangling skin. Long-lasting clinical results with a low recurrence rate and a satisfactory aesthetic outcome are achieved with no deformation of the ear framework.

Abstract
The use of sutures is a common practice in plastic surgical procedures. The potential risk of developing an allergic reaction to suture materials exists. To the best of the authors' knowledge, this is the first case reported in the literature of such a reaction in aesthetic breast surgery. The aim of this review is to raise the awareness of possible allergic and infective or inflammatory reactions to the suture material and to expand the knowledge of the management and interventions which are critical for patient safety and satisfaction. More research is needed to study this challenging topic.

Abstract
The overproduction of altered collagen fibers and the overexpression of Tumor Growth Factor-β must be blocked in order to interrupt the growth process within a keloid scar. This can barely be achieved with the classical therapeutic methods. The results of keloid treatment are difficult to predict and the recurrence rate is usually over 50 %. In addition, some of the procedures used (e. g. irradiation) may induce additional health risks. Intralesional cryosurgery offers a therapeutic alternative that has been evaluated since more than a decade. Our own experience in more than one thousand keloid treatments allows a critical evaluation of the classification in those keloid types, which are recommended to be treated with the technique and those, which may not respond.

Abstract
Infantile Digital Fibromatosis (IDF) is a rare benign lesion that can affect the fingers, often appearing at birth or early on in life. Treatment is controversial due to a high recurrence rate following surgical excision, and the tendency of the lesions to regress or resolve completely after the age of one year. Functional loss has rarely been described. We describe a case of IDF with joint contracture and significant functional deficit that was treated with cryotherapy and post procedural occupational therapy with an excellent result. Indications for treatment and cryotherapy as a therapeutic modality for IDF are discussed.

Abstract
ZusammenfassungDie Überproduktion veränderter Kollagenfasern und die Überexpression von Tumor-Growth-Factor-β muss gehemmt werden, um den Wachstumsprozess innerhalb einer Keloidnarbe zu unterbrechen. Dies kann mit den klassischen Therapieverfahren kaum gelingen. Die Behandlungsergebnisse der Keloidtherapie sind nur schwer vorherzusagen und die Rezidivrate liegt meist über 50 %. Darüber hinaus können einige der eingesetzten Verfahren (z. B. Bestrahlung) zusätzliche gesundheitliche Risiken verursachen. Die intraläsionale Kryochirurgie bietet eine seit nunmehr 10 Jahren erprobte Therapiealternative an. Eigene Ergebnisse von weit über tausend Behandlungen von Patienten mit Keloiden ermöglichen eine kritische Analyse, um eine Unterscheidung der Keloide, die gut zu behandeln sind, von denen, die sich für eine Behandlung weniger oder gar nicht eignen, treffen zu können.

Abstract
Keloid disease is a recurrent fibroproliferative cutaneous tumor of unknown pathogenesis for which clinical management remains unsatisfactory. To obtain new insights into hitherto underappreciated aspects of keloid pathobiology, we took a laser capture microdissection-based, whole-genome microarray analysis approach to identify distinct keloid disease-associated gene expression patterns within defined keloid regions. Identification of the aldo-keto reductase enzyme AKR1B10 as highly up-regulated in keloid epidermis suggested that an imbalance of retinoic acid metabolism is likely associated with keloid disease. Here, we show that AKR1B10 transfection into normal human keratinocytes reproduced the abnormal retinoic acid pathway expression pattern we had identified in keloid epidermis. Cotransfection of AKR1B10 with a luciferase reporter plasmid showed reduced retinoic acid response element activity, supporting the hypothesis of retinoic acid synthesis deficiency in keloid epidermis. Paracrine signals released by AKR1B10-overexpressing keratinocytes into conditioned medium resulted in up-regulation of transforming growth factor-β1, transforming growth factor-β2, and collagens I and III in both keloid and normal skin fibroblasts, mimicking the typical profibrotic keloid profile. Our study results suggest that insufficient retinoic acid synthesis by keloid epidermal keratinocytes may contribute to the pathogenesis of keloid disease. We refocus attention on the role of injured epithelium in keloid disease and identify AKR1B10 as a potential new target in future management of keloid disease.

Abstract
BACKGROUND Incidences of basal cell carcinoma (BCC) on the lower extremities in elderly patients are rising. Surgical approaches to the treatment of BCC are subject to possible difficulties in healing, failure of skin grafts, and wound infection. This study assessed the efficacy of intralesional cryosurgery in the treatment of BCC of the lower limbs in elderly patients. METHODS This study included eight patients aged >60 years in whom a total of 10 nodular or superficial BCCs of the lower limbs were confirmed by biopsy. The patients' medical histories revealed comorbidities including hypertension, diabetes, hypercholesterolemia, venous insufficiency, and deep vein thrombosis of the legs, congestive heart failure, chronic renal failure, and ischemic heart disease. Using liquid nitrogen, an intralesional cryosurgery needle (CryoShape) was inserted into the tumor to facilitate its complete freezing. Treatment success was confirmed by biopsy taken approximately 3 months after complete healing of the cryo-wound. RESULTS The average size of the lesions treated was 2.49 cm(2) (16.4 × 15.2 mm). Mean recovery time was 79.9 days. Biopsies were obtained at a mean of 85.3 days after the wound had healed. All 10 biopsies verified the complete destruction of the tumor. There was no evidence of wound infection or tumor recurrence over a follow-up period of 28 months. CONCLUSIONS This study demonstrates that a single intralesional cryosurgery session can completely eradicate BCC on the lower extremities in elderly patients. This technique is associated with relatively minor complications, is well tolerated, and represents a safe and effective therapeutic modality for BCC of the lower limbs.

Abstract
Pressure necrosis which might be followed by skin necrosis and implant extrusion is a dreaded complication of breast reconstructive surgery. Over the years, several techniques have been introduced to address this challenging problem. We offer a novel surgical technique to confront this perplexing complication. By using the capsule of the implant as a turnover flap, the soft tissue coverage is enhanced thereby decreasing the pressure between the breast prosthesis and the over-laying skin. The technique is simply reproduced, requires no new incisions, and avoids further morbidity to the involved breast reconstructed patient.

Abstract
BACKGROUND In some leg ulcer patients there is cancer that is responsible for lack of healing of such a wound. AIM This study was aimed at prospective analysis of histopathology of non-healing wounds (NHWs) in the patient presenting with high and low suspicion for ulcerating carcinoma. MATERIAL AND METHODS Forty patients with NHWs were enrolled and had been prospectively divided into two groups: 25 patients with high suspicion for ulcerating carcinoma according to their medical history and physical examination, and the second group of 15 patients without suspicion for malignancy (control group). All NHWs were photographed and underwent biopsies. RESULTS In the control group biopsies did not reveal cancers. On the contrary, in 10 patients (40%) from high suspicion group biopsies revealed cancers: seven basal cell carcinomas (BCCs), one - malignant melanoma, one - Bowen's disease and one - squamous cell carcinomas. Histopathology of six of seven BCCs suggested that non-healing benign wound might have preceded malignancy. We found that leg ulcers which were small (wound area less than 3 cm(2) ), longstanding (duration 24 ≤ weeks), presenting with granulation tissue covering ≥75% of the wound area, with a dull pink appearance of the granulation tissue, or an atypical clinical presentation, can actually be an ulcerating carcinoma. Dull pink granulation tissue or an atypical clinical presentation of ulceration, as a single clinical finding, suggested an underlying malignancy with a statistical significance (71.5% vs. 0%; P = 0.001 and 27.8% vs. 0%; P = 0.0049 respectively). CONCLUSIONS Prevalence of malignancy, primarily: BCCs in NHWs, may be higher than expected and clinical features suggestive of such a nature of ulcer are an indication for diagnostic biopsy.

Abstract
Hypertrophic scars and keloids following aesthetic surgery, which ignite patient dissatisfaction, are difficult to handle. Intralesional cryosurgery for the treatment of such scars has been introduced. This study was designed to evaluate the efficacy of this technology in the treatment of such scars and to assess the reduction of dissatisfaction. Eleven scars (on 11 patients) were treated by intralesional cryosurgery, following breast surgery, otoplasty, face-lifting, and brachioplasty. Each patient scored the concern from the scar and the scar deformity (scale from 1 to 5) prior and following treatment (higher score represents least satisfaction and a severe deformity). The follow-up period was between 3 months and 8 years. The results demonstrated a significant reduction in concern and deformity scores compared with before the cryotreatment (P = .001). The intralesional cryosurgery technique provides the plastic surgeon with an effective instrument to treat hypertrophic scars and keloids following aesthetic surgery, thus reducing the dissatisfaction of patients.

Abstract
BACKGROUND Eyebrow ptosis and hooding gives the eye a sad, heavy look that often disturbs the visual field. OBJECTIVE A direct extended scalpel-shaped brow lift is proposed to correct this functional and aesthetic disfigurement. This manuscript reviews our experience with the presented technique and evaluates the clinical results in the light of ongoing concerns regarding the appearance of the postoperative scar. In addition, the indications and patient selection criteria are elaborated. METHODS An incision was made along the superior border of the brow, extending laterally and downward, often within a "crow's feet" crease. The upper border of the incision joined the 2 extremities of the skin outline of the lower incision in a gentle convex curve. The general outline of the incision resembled the shape of a No. 20 scalpel blade, in which the maximal width is located laterally at the temple "crow's feet" area. RESULTS Fourteen patients, including 8 males (48-74 yrs of age) and 6 females (67-71 yrs of age) underwent this procedure. The surgical scar was hardly noticeable after 6 to 9 months, and often fell within a preexisting crow's feet crease. Elimination of some of the crow's feet occurred in all the patients. Subjective and objective functional relief with respect to the vision field and the heavy-feeling brow and satisfaction with the aesthetic result were reported by all patients. CONCLUSIONS The most appropriate candidates for the direct extended scalpel-shaped brow lift are patients older than 50 years of age, with eyebrow ptosis accompanied with lateral hooding, well developed crow's feet, and forehead skin laxity; long, dense eyebrows, and low transverse forehead wrinkles aid in concealment of the scar.

Abstract
Based on clinical experience, the senior author has become convinced that wounds produced to correct the deformities of patients with neurofibromatosis (NF-1) have produced remarkably good scars, the interesting feature being that progression to keloid or hypertrophic scar is rare. The other point noted was that this situation did not change, no matter the patient's race or skin color. There have been few reports describing or discussing this hypothesis. The purpose of this study was to investigate whether wounds produced in the patients with NF-1 produce keloid or hypertrophic scars. The patients with solitary neurofibroma were also included in this study; these were compared with the NF-1 group. This was conducted as a multicenter study. Patients with neurofibromatosis/solitary neurofibroma, who were operated on from 1990 to 2000, were evaluated by reviewing their medical charts and photographs retrospectively. The patients were treated in centers from five different countries. The analysis was undertaken based on the following points: 1) age and sex at surgery; 2) race of the patients; 3) past and family histories of hypertrophic scar and keloid; 4) surgical site(s); 5) diagnosis, NF1 or solitary neurofibroma; 6) surgical complications; 7) number of reoperations to manage the complications; 8) adjuvant therapy for the tumor; 9) depth of the tumors; and 10) incidence of malignant degeneration. A total of 101 cases with neurofibromatosis or solitary neurofibroma was analyzed. The age at surgery ranged from 1 year 6 months to 74 years; sex ratio was 47 males and 54 females. The racial distribution of the patients was 13 white, 13 black, 3 Hispanic, and 58 Asian. There was no past or family history of hypertrophic scar or keloid. The surgical sites were head and neck in 70 cases, trunk in 20 cases, upper extremities in 22 cases, and lower extremities in 20 cases. The clinical diagnosis was NF-1 in 57 cases, solitary neurofibroma in 35 cases, plexiform neurofibroma in four cases, and no distinct clinical diagnosis in five cases. There were no other types of neurofibromatosis. Hematoma and white wide scar were the main postoperative complications found in six cases of NF-1. Infection was also noted in four cases. However, no patient developed hypertrophic scar or keloid in the neurofibromatosis group, whereas two cases showed hypertrophic scar in the solitary neurofibroma group. The outcome showed that the patients with NF-1 and plexiform neurofibroma, no matter the racial group, produce good scars without keloid or hypertrophic changes, whereas solitary neurofibroma has a potential to cause hypertrophic scar.

Abstract
In this case report, we present a patient who used a nasal cannula for oxygen supplementation and suffered deep, second-degree burns to his nose and left leg when an electrical spark shot out of the cable's connection socket while the cellular phone was ringing and the cable was, simultaneously, being disconnected from the socket. The cellular phone, a device commonly thought by many people to be both useful and safe, thus has the potential to serve as a heat source that might ignite and cause burns.

Abstract
BACKGROUND This 15-month study was designed to compare the effect of skin surface temperature on skin pigmentation following a single intralesional or contact cryosurgical treatment of keloids. PATIENTS/METHODS Thirty Caucasian patients with 45 keloids present for more than 6 months were included in this study. Twenty-one keloids were treated by the contact method while the remaining 24 scars were managed using an intralesional cryosurgery technique. The skin surface temperature at the keloids was measured and recorded using a Ni/Cd thermocouple. Four variables of the thermal history were evaluated with the contact and the intralesional methods, namely cooling rate, hold time, end temperature and thawing rate. Assessment of the local hypopigmentation was performed 6 months after the treatment using a pigmentation scale. RESULTS Significantly slower cooling (6.09 +/- 4.56 degrees C/min) and thawing rates (54.52 +/- 32.17 degrees C/min) were recorded with the intralesional cryosurgery method when compared with the cooling rates (13.47 +/- 9.04 degrees C/min) and thawing rates (89.00 +/- 86.42 degrees C/min) of the contact method (P < 0.000001). The end temperature of the contact technique was significantly cooler (-46.77 +/- 14.74 degrees C) when compared with that of the intralesional method (-15.55 +/- 6.77 degrees C) (P < 0.000001). There was a trend for the hold time of intralesional cryosurgery to be longer (82.67 +/- 138.03 s) than that of the contact method (16.86 +/- 23.49 s) (P < 0.059). A significant difference in skin pigmentation was demonstrated between the two cryosurgical methods. In 91.7% of the keloids treated by the contact technique a significant hypopigmentation was noticed, while no marked hypopigmentation was detected in the skin surface of the keloids treated by the intralesional method (P < 0.0001). CONCLUSION We hypothesize that the thermal history of the skin surface during the intralesional cryosurgery technique provides a better survival environment for the melanocytes than the contact method, thus producing a lower rate of permanent hypopigmentation and disfiguring.

Abstract
BACKGROUND The versatility of the gastrocnemius muscle for reconstruction of defects in the knee region from the upper third of the calf to the lower third of the thigh is well known. Possible limitations of this flap include difficulties in covering multiple separate wounds in the same area as well as contour deformity because of the flap bulkiness. The findings in this study extend the versatility of the gastrocnemius muscle flap by splitting each head into two segments allowing for the closure of multiple defects. METHODS Studied was the vascular anatomy of 15 fresh cadaveric lower extremities. Contrast material was injected into the sural artery and this showed the bifurcation of the pedicle in the upper third of the muscle. A constant intramuscular vascular pattern represented by two main longitudinal branches permitted the safe division of each head. Based on these anatomic studies, segmentation was performed of the gastrocnemius muscle flap in 29 patients. In 13 cases were used, one or two muscle segments and in 16 cases, three muscle segments were transposed. RESULTS All of the flaps survived. Minor complications, such as wound dehiscence, cellulitis, or hematoma, were encountered in seven patients. Except for one patient with persistent drainage from osteomyelitic bone, all the wounds closed successfully. CONCLUSIONS The authors report the safe splitting of the distal gastrocnemius muscle in 29 patients based on vascular anatomic studies. The advantages of gastrocnemius segmentation include the possibility of covering multiple defects with less contour deformity.

Abstract
BACKGROUND A multicenter study was conducted to test the ability of electrical impedance scanning to differentiate between benign and malignant skin lesions. The performance of a dual electrical impedance scanning/image analysis device was also assessed. METHODS Electrical impedance scanning measurements of 449 preoperative lesions found on 382 patients and including 53 melanomas from the trunk and extremities were performed. Results were correlated with histopathologic findings. In addition, ABCD parameters for the lesions were automatically calculated by the system. RESULTS Electrical impedance scanning detected melanomas of the trunk and extremities with 91 percent sensitivity and 64 percent specificity. Moreover, sensitivity of electrical impedance scanning was increased to 100 percent for in situ and thin melanomas of smaller size (n = 27). Visual examination identified as malignant only 67 percent of these early tumors (p = 0.002). Clinical examination detected 96 percent of the larger or thicker melanomas (n = 26), whereas electrical impedance scanning detected only 81 percent of them. Combined electrical impedance scanning and image analysis detected 100 percent of the melanomas, independent of their thickness, and with no significant decrease of specificity. Because of electrical differences between the head/neck and the rest of the body, the assessed electrical impedance scanning parameters were not adequate for the diagnosis of melanomas from the head and neck. CONCLUSIONS A validation study proved the value of electrical impedance scanning as a noninvasive technique for detection of melanoma lesions of the trunk and extremities, specifically, of in situ and thin type. In addition, image analysis was shown to be a valuable, complementary procedure. New parameters should be designed to optimize the performance of electrical impedance scanning for melanomas of the head and neck.

Abstract
Evidence is accumulating in favor of classifying erectile dysfunction (ED) as a vascular disorder. There are three main clinical scenarios in which ED and coronary artery disease (CAD) may coexist: the patient with ED who later develops CAD, the patient with overt CAD who is casually found to have ED, and the patient with acute coronary syndrome who has normal sexual function. This study presents three cases and discusses a "putative" pathophysiological mechanism underlying all these clinical presentations. Further studies, coupling functional and structural changes of coronary circulation with those of penile (i.e., dynamic penile test) circulation in each of these situations are mandatory to support this hypothesis.

Abstract
The objective of this study was to report long-term success rates for penile revascularization (PR) and investigate factors responsible for failures. During the past 10 y, data were obtained on 52 patients who underwent PR. Surgical technique was selected according to preoperative arteriographic findings. The mean age was 28.5 y and the mean follow-up was 70.8 months. Success was defined as satisfactory intercourse without additional therapy. Overall success was 48%. Patients under 28 y showed a 73% success rate vs 23% in the older ones (P=0.0003). Nonsmokers had a 57% success compared to 29% in smokers (P=0.05). The presence of venous leak and type of procedure had an insignificant impact on success (P=0.33 and 0.23 respectively). To conclude, this curative treatment option is limited to a selective population with vasculogenic erectile dysfunction. We found that the cure rate of this procedure is maintained and long-term follow-up shows good results, especially in the young nonsmokers.

Extended Upper Blepharoplasty for Lateral Hooding of the Upper Eyelid Using a Scalpel-Shaped Excision: A 13-Year Experience. Plast Reconstr Surg 2004; 113:1028-35; discussion 1036.

Abstract
Excess skin of the upper lids is often accompanied by lateral overlap of skin with crow's feet because of the absence of fixation to the tarsal plate, giving the eye a sad, heavy look that often disturbs the lateral visual field. The accepted crescent-shaped blepharoplasty is somewhat convex, which is widest at the center of the lid with or without a lateral extension. However, in patients who have normal brow position or minimal eyebrow ptosis and whose main concern is the excess upper eyelid skin and lateral hooding, such a crescent excision may not suffice. A scalpel-shaped excision that is widest laterally and that tapers to a point medially will extirpate the maximal skin where it is most needed and overcome the skin excess in the lateral aspect of the upper lid. Between 1990 and 2002, 301 white patients (275 women and 26 men) between the ages of 33 and 79 years were operated on using the extended scalpel-shaped upper blepharoplasty technique. The follow-up period was more than 1 year. The lower margin of the incision is along the supratarsal crease, about 10 mm above the ciliary line. It begins medially about 1 cm above and lateral to the medial canthus. Above the lateral canthus, the skin marking is gently curved upward and outward, often within a natural skin crease or crow's feet to reach a little below and slightly beyond the lateral extremity of the eyebrow. The upper border of the incision joins the two extremities of the skin outline in a gentle convex curve. The general outline of the incision takes on the shape of a number 20 scalpel blade in which the maximal width is located laterally. Following excision of the excess skin and removal of protuberant fat pads if needed, suturing is executed from lateral to medial. The final suture line is in the form of an oblique flattened lazy S. Following the removal of the stitches on the fifth postoperative day, no wound dehiscence was noticed at the lateral scar zone. In the older individuals, due to the lax skin, the scar becomes scarcely noticeable with time and often falls within a pre-existent crow's feet crease. Elimination of some of the crow's feet was also demonstrated. In patients with visual field impairment, significant functional and visual improvement was achieved. Most patients mentioned a pleasing postoperative open "Oriental" look of the eyes. The extended scalpel-shaped upper blepharoplasty adequately deals with the hooding of the skin laterally. This technique overcomes the excess of skin in both vertical and horizontal directions, since in suturing the lateral part of the skin defect in an oblique plane, slack skin is taken up transversely, and the technique provides some indirect upward support to the lateral eyebrow. In the absence of crow's feet in the younger person, this technique is not recommended because the lateral part of this suture line is visible, especially if the scar widens.

Abstract
Chest wall deformity is one of the potential complications of rib cartilage harvesting for auricular reconstruction. An eight year old boy underwent two stage microtia reconstruction using the 6th-9th costal cartilage for the 3-D cartilage framework. One year later an anterior chest wall deformity was noticed with bulging of the 5th rib, asymmetry of the lower rib cage line and deviation of the lower part of the sternum. The anterior chest wall is made of ribs, sternum and respiratory muscles forming a dynamic structure. By using these pieces of rib cartilage an imbalance is created in which the respiratory muscles pull the edges of the remaining ribs, thereby creating the deformity. It is especially critical during the growth phase. The 3-D CT scan demonstrates the chest deformity. We present a literature review and recommendations on how to reduce the complications when using rib cartilage for auricular reconstruction are presented.

Abstract
Although therapeutic management of hypertrophic scars and keloids using contact or spray cryosurgery has yielded significant improvement or complete regression of hypertrophic scars and keloids, it requires one to 20 treatment sessions. This study was designed to assess the clinical safety and efficacy of an intralesional needle cryoprobe method in the treatment of hypertrophic scars and keloids. Ten patients, ranging in age from 3 to 54 years, with a total of 12 hypertrophic scars and keloids of more than 6 months duration and of diverse causes, were included in this study. The 18-month trial evaluated volume reduction of the hypertrophic scars and keloids after a single session of intralesional cryotherapy. Objective (hardness and color) and subjective (pain/tenderness and itchiness/discomfort) parameters were examined on a scale of 0 to 3 (low score was better). Pretreatment and posttreatment histomorphometric studies of the collagen fibers included spectral picrosirius red polarization and fast Fourier transformation orientation index. A specially designed cryo-needle was inserted into the long axis of the hypertrophic scars and keloids so as to maximize the volume of the hypertrophic scars and keloids to be frozen. The cryo-needle was connected by an adaptor to a cryogun filled with liquid nitrogen, which was introduced into the cryoprobe, thereby freezing the hypertrophic scars and keloids. After the hypertrophic scars and keloids were completely frozen, the cryoprobe defrosted and was withdrawn. An average of 51.4 percent of scar volume reduction was achieved after one session of intralesional cryosurgery treatment (average preoperative hypertrophic scars and keloids volume, 1.82 +/- 0.33; average posttreatment volume, 0.95 +/- 0.21; p < 0.0022). Significant alleviation of objective and subjective clinical symptoms was documented. Mild pain or discomfort during and after the procedure was easily managed. Only mild local edema and epidermolysis, followed by a short reepithelialization period, were evident. During the 18-month follow-up period, there was no evidence of bleeding, infection, adverse effects, recurrence, or permanent depigmentation. The histomorphometric analysis demonstrated rejuvenation of the treated scars (i.e., parallelization) and a more organized architecture of the collagen fibers compared with the pretreated scars. This study demonstrated the increased efficacy of this method as a result of increased freezing area of deep scar material compared with that obtained with contact/spray probes. As a result, fewer treatment cycles are needed. Because the reepithelialization period is short, treatment intervals, if any, can be shortened to 2 to 3 weeks. This intralesional cryoneedle method is simple to operate and safe to use, it necessitates less postoperative care of the wound, and it can easily be added to any preexisting cryosurgical unit.

Abstract
Androgenetic Alopecia (AA) afflicts a large part of the population and of the many treatments available today none is completely satisfactory. Testing the efficacy and safety of a novel topical treatment for AA which is based on cell culture medium supplemented with insulin, thyroxin and growth hormone (CCM). The 48 participants classified as androgenetic alopecia Type II, III or IV on the Hamilton scale, concluded a randomized, vehicle-controlled, double-blind trial of 6 months duration. Under occlusive cover the gel was self applied for at least 3 hours daily. Evaluation was based on hair counts, investigator global assessment and participants self-administered questionnaire. Cessation of hair loss was reported by most participants within 28 weeks, and further confirmed by the hair count (HC) in ~80% of participants. Moreover, as early as 4 months after the start of the treatment, a time dependent increase of up to 50% in HC was observed. The average change in HC between the two groups differed significantly (p=0.007), with values of 4.1% for control and 13.8% for CCM. Following 4 months of treatment, a time dependent increase in HC (>10%) above minimal was observed in 55% of the CCM and 25% of the control and this trend continued. At 6 months 63% of the CCM and 33% of the control group exhibited increase of HC higher than 10%. The average increase in HC in the CCM and the control groups was 17.1% and 8.9% respectively (p=0.035). Self evaluation questionnaires revealed a time dependent increase in satisfaction in the CCMusers compared to the control. While the average score at T2 was similar in CCM and control (2.7 and 2.6 respectively), the score at T6 in the CCM increased to 5.9 and decreased to -0.4 in the control (p=0.007). Global-clinical evaluation following six months treatment revealed significantly (p=0.02) more hair loss in the control group (40%) compared to the CCM (7%) treated group. CCM was found effective in treating androgenetic alopecia in men. It induced cessation of hair loss, increased rate of hair growth and appearance of new hair. No side effects were reported or observed.

Abstract
One of the most difficult reconstructive procedures is the reconstruction of the auricle, since it has a very difficult form to imitate. During the last four decades there have been numerous reconstructive attempts throughout the world especially for cases of microtia. The principle is to build a framework from cartilage that will be used for the reconstruction. A prominent personality in this field is Dr. Burt Brent, who is identified with this challenge. Dr. Brent has established the method of reconstruction in four stages. In order to limit the operative stages Dr. S. Nagata suggested doing the reconstruction in two stages, using a different cartilage framework and elevating the auricle using temporo-parietal fascial flap and skin graft. His method was improved further by Dr. Francoise Firmin. The first stage is conducted at the age of 9-10, during which the ipsilateral rib cartilage is harvested, carved and put together into a cartilage framework and than inserted into a skin pocket in the area awaiting reconstruction. Half a year later, the auricle is elevated by inserting a wedge cartilage behind it, covering with temporo-parietal fascial flap and skin graft. Our experience using this method in ten microtia cases proves that it is a good choice in total auricle reconstruction for microtia patients.

Abstract
This article reports on the sensitivity and positive predictive value of clinical diagnosis of benign and malignant skin tumors by expert plastic surgeons in an Israeli clinic. Most published reports have focused on the sensitivity of clinicians' diagnoses, a general measure of the physician's skill that does not predict the rate of accuracy of a physician's diagnoses. Our study of 835 lesions in 778 patients, one of the largest Israeli series, assesses the clinical diagnosis of malignant and benign skin tumors and is one of the few that provide information on the positive predictive value, the measure that is of interest to both physicians and patients. The majority of tumors were benign (56.8 percent), 31.6 percent were malignant, and 11.6 percent were premalignant. Among the 474 benign lesions, 46 percent were nevi. The most common nevi subclass was compound nevi (53 percent), 9 percent of the nevi were dysplastic, and 5 percent were blue nevi. The most common malignant tumor was basal cell carcinoma, accounting for 78 percent of malignant tumors. Although sensitivity for clinical diagnosis of malignancy was 91.3 percent, the positive predictive value for clinical diagnosis of malignancy was 71.3 percent. The sensitivity rate for clinically diagnosing premalignant tumors was 42.3 percent, whereas the positive predictive value for these diagnoses was higher (64.1 percent). The sensitivity rate for diagnosis of all benign lesions was 85.9 percent, and the positive predictive value was 94.2 percent. The sensitivity rate for diagnosis of all nevi was 87.6 percent, and the positive predictive value was 85.7 percent: i.e., only seven of the 218 pathologically proven diagnoses of nevi (3.2 percent) were falsely diagnosed as malignant lesions. Even more interestingly, five of the 223 clinical diagnoses of nevi (2.2 percent) were pathologically proven to be malignant melanomas, and seven were found to be premalignant lesions (3.1 percent). It was concluded that publications which report only on the sensitivity neglect to provide information of interest regarding the positive predictive value. Often, positive predictive value is qualitatively different from the sensitivity, and thus relying only on the sensitivity may lead to incorrect evaluation of a clinical judgment, which may result in erroneous surgical decisions.
