Intricacies of the Single-Scar Technique for Donor Harvesting in Hair Transplantation Surgery

DERMATOLOGIC SURGERY, Issue 6 2004
Dominic A. Brandy MD
Background. Although single-scar techniques have been published and are used by approximately half of all surgeons, this approach is not as common as one might suspect. Objective. The objective is to demonstrate several surgical gems that make the single-scar donor technique a viable method that can be performed by the vast majority of hair restoration surgeons. Methods. The author presents various techniques such as postauricular skin elevation, subcutaneous undermining of the nape scalp, debulking of underlying scar tissue, temporary staple closure, and permanent double-layered closure using magnification (preferably 2.5 × or greater). All of these contribute to a loose closure with an aesthetically pleasing single donor scar after multiple surgeries. Results. Utilizing the various techniques described in this article, the author has been able to achieve a cosmetically attractive single scar after multiple surgeries in the vast majority of patients. Conclusion. An aesthetically pleasing single, thin donor scar is preferable to multiple scars or a thick single scar at the donor area after multiple hair restoration surgical procedures. The author presents several methods that help hair restoration surgeons conquer some of the obstacles that have deterred them from performing a single-scar technique with consistently excellent results.

Alcohol Neurolysis of the Sciatic and Femoral Nerves to Improve Pressure Ulcer Healing

PAIN PRACTICE, Issue 2 2009
Denise Wilkes MD
Abstract Successful pressure ulcer treatment is challenging and is often plagued with prolonged hospitalizations, multiple surgeries, and high recurrence rates. Pressure ulcer secondary to spinal cord injury is further complicated by spasticity, which contributes to both ulcer continuance and healing. This report illustrates the use of neurolytic regional techniques for spasticity control and pressure ulcer healing. Case report: We present our experience with a paraplegic man who suffered from chronic right trochanteric and ischial pressure ulcers that failed to heal despite surgical and conservative treatment. We report the successful treatment of knee and hip flexor spasticity with a femoral and sciatic alcohol neuroablation technique. It was not until the successful control of his lower extremity spasticity that the pressure ulcers showed signs of healing. Neuroablation nay be considered for spasticity control when more conservative approaches fail or are not feasible. [source]

Patterns of latex allergen recognition in children sensitized to natural rubber latex

PEDIATRIC ALLERGY AND IMMUNOLOGY, Issue 1 2006

Single recombinant latex allergens permit the study of the pattern of sensitization to individual allergens. We aimed to quantify the IgE-response to individual latex allergens in children sensitized to latex. The study group included 31 latex-sensitized children: 26 operated at least twice, 20 of them with spina bifida; two children with one operation and three atopic non-operated children. IgE antibodies to rHev b 1, rHev b 3, rHev b 5, rHev b 6.01, rHev b 7.02 and rHev b 8, coupled to ImmunoCAPs, were measured in each serum. IgE responses to rHev b 1, rHev b 5 and rHev b 6.01 were found in 17 children each, and their mean ± s.d. levels were 5 ± 7.4, 16.8 ± 14 and 10 ± 18 kU/l, respectively. IgE responses to rHev b 3 (4 ± 5.4 kU/l) were found in eight children. Two children had IgE to rHev b 7 (1.7 and 3.2 kU/l), and none to rHev b 8. Four sera were negative to all tested recombinant allergens. We divided the patients in three groups: sensitized only to rHev b 1, sensitized only to rHev b 5 and/or rHev b 6.01, and sensitized to both rHev b 1 and to rHev b 5 and/or rHev b 6.01. The three groups had the same profile of clinical features. Hev b 5 induces the quantitatively higher IgE responses in children with multiple surgeries sensitized to latex. Responses to Hev b 6.01 equal those of Hev b 1. [source]

Quantitative analysis of immunoglobulin E reactivity profiles in patients allergic or sensitized to natural rubber latex (Hevea brasiliensis)

CLINICAL & EXPERIMENTAL ALLERGY, Issue 11 2007

Summary Background Characterized native and recombinant Hevea brasiliensis (rHev b) natural rubber latex (NRL) allergens are available to assess patient allergen sensitization profiles. Objective Quantification of individual IgE responses to the spectrum of documented NRL allergens and evaluation of cross-reactive carbohydrate determinants (CCDs) for more definitive diagnosis. Methods Sera of 104 healthcare workers (HCW; 51 German, 21 Portuguese, 32 American), 31 spina bifida patients (SB; 11 German, 20 Portuguese) and 10 Portuguese with multiple surgeries (MS) were analysed for allergen-specific IgE antibody (sIgE) to NRL, single Hev b allergens and CCDs with ImmunoCAPÔ technology. Results In all patient groups rHev b 5-sIgE concentrations were the most pronounced. Hev b 2, 5, 6.01 and 13 were identified as the major allergens in HCW and combined with Hev b 1 and Hev b 3 in SB. In MS Hev b 1 displayed an intermediate relevance. Different sIgE antibody levels to native Hevea brasiliensis (nHev b) 2 and rHev b 6.01 allowed discrimination of SB with clinical relevant latex allergy vs. those with latex sensitization. Sensitization profiles of German, Portuguese and American patients were equivalent. rHev b 5, 6.01 and nHev b 13 combined detected 100% of the latex-allergic HCW and 80.1% of the SB. Only 8.3% of the sera showed sIgE response to CCDs. Conclusions Hev b 1, 2, 5, 6.01 and 13 were identified as the major Hev b allergens and they should be present in standardized latex extracts and in vitro allergosorbents. CCDs are only of minor relevance in patients with clinical relevant latex allergy. Component-resolved diagnostic analyses for latex allergy set the stage for an allergen-directed immunotherapy strategy. [source]
