Reconstruction of penile skin loss by superficial circumflex iliac perforator (SCIP) pedicled flap after Fournier's gangrene

INTRODUCTION

Fournier's gangrene is a serious pathology with a high mortality rate. Treatment requires a large debridement of necrotized tissues, conducing to a skin loss, requiring a reconstruction, which may involve different surgical techniques, depending on the context as well as the size and location of the skin loss. The most common covering technique uses split-thickness skin grafting, which however presents a risk of contracture.

CASE

Our 63 years old patient presented a Fournier's gangrene, leading to pubic and circular penile skin defects after multiple debridements. We decided to practice a right superficial circumflex iliac perforator (SCIP) pedicled flap to reconstruct the penile skin sheath. The flap was rotated 180 degrees and rolled around the penis.

DISCUSSION

The inguinal pedicle flap is described for penile reconstruction, the SCIP flap for perineal reconstruction, and even bilateral SCIP flaps for performing phalloplasty, but SCIP pedicled flap is not already described for isolated penile skin sheath reconstruction. Skin loss in our patient was not extensive, permitting us to perform this surgical technique. To go further, note the possibility of carrying out this reconstruction by a super-thin SCIP flap, as a pure skin graft flap.

CONCLUSION

The SCIP pedicled flap seems us to be a safe technique for penile skin reconstruction and a good alternative to the usual skin grafts, especially regarding the lower risk of contracture, and low donor-site morbidity.

Is unicentric familial papillary thyroid microcarcinoma different from multicentric?

BACKGROUND

Familial papillary thyroid microcarcinoma (FPTMC) appears to be more aggressive than sporadic papillary thyroid microcarcinoma (SPTMC). However, there are authors who indicate that unicentric FPTMC has a similar prognosis to SPTMC. The objective is to analyze whether unicentric FPTMC has a better prognosis than multicentric FPTMC.

DESIGN AND METHODS

Type of study: National multicenter longitudinal analytical observational study.

STUDY POPULATION

Patients with FPTMC.

STUDY GROUPS

Two groups were compared: Group A (unicentric FPTMC) vs. Group B (multicentric FPTMC).

STUDY VARIABLES

It is analyzed whether between the groups there are: a) differentiating characteristics; and b) prognostic differences.

STATISTICAL ANALYSIS

Cox regression analysis and survival analysis.

RESULTS

Ninety-four patients were included, 44% (n = 41) with unicentric FPTMC and 56% (n = 53) with multicentric FPTMC. No differences were observed between the groups according to socio-familial, clinical or histological variables. In the group B a more aggressive treatment was performed, with higher frequency of total thyroidectomy (99 vs. 78%; p = 0.003), lymph node dissection (41 vs. 15%; p = 0.005) and therapy with radioactive iodine (96 vs. 73%; p = 0.002). Tumor stage was similar in both groups (p = 0.237), with a higher number of T3 cases in the group B (24 vs. 5%; p = 0.009). After a mean follow-up of 90 ± 68.95 months, the oncological results were similar, with a similar disease persistence rate (9 vs. 5%; p = 0.337), disease recurrence rate (21 vs. 8%; p = 0.159) and disease-free survival (p = 0.075).

CONCLUSIONS

Unicentric FPTMC should not be considered as a SPTMC due to its prognosis is similar to multicentric FPTMC.

Correlation vs. exchange competition drives the singlet-triplet excited-state inversion in non-alternant hydrocarbons

In this work, we focus on the understanding of the driving force behind the S1-T1 excited-state energy inversion (which would thus violate Hund's rule, making the S1 state lower in energy than the T1 state) of two non-benzenoid non-alternant hydrocarbons, composed of odd-membered rings. The molecules considered here have identical chemical composition but different atomic configuration in space. The delicate interplay between structural and electronic factors that might induce inversion and its energy extension, only by a few meV, is systematically investigated here by state-of-the-art calculations. Qualitative and quantitative accurate predictions are obtained employing post-HF methods, thanks to the balanced and careful inclusion of electron correlation effects. The obtained results might guide and rationalize new searches for molecules violating Hund's rule, concomitantly demonstrating the importance of key contributions from the theoretical method of choice.

Spare part's free contralateral medial plantar flap for emergency reconstruction in a bilateral lower legs ballistic trauma

The medial plantar flap is frequently used in heel reconstruction and has been described since 1969. We took care of a 25-year-old patient with a bilateral ballistic trauma and open fractures to the distal third of both legs. Given the seriousness of the damage to the left lower limb, a trans-tibial amputation had to be performed. Concerning the right lower limb, we decided to cover the defect with a spare part's free medial plantar flap thanks to the amputated fragment. The extremity spare tissues principle is already known and described, more particularly concerning hands, in emergency traumatic surgery and in planned surgery, mainly concerning thumb reconstruction, for example for hypoplasia or after traumatic amputation. Apart from an article on the use of foot spare part in the coverage of amputation stumps, no article has reported the use of a foot spare part in reconstructive surgery, even more in traumatic surgery. We believe that the use of an extremity spare tissues should be considered in rare cases where this is possible, in order to reduce donor-site morbidity in the context of reconstructive surgery.

[Is the internet a reliable source of information for patients eligible for breast reconstruction by DIEP flap?]

INTRODUCTION

Informing breast reconstruction patients is a major factor in shared medical decision-making. In the light of the development of multimedia, patients face a paradoxical duality: the possibility of consulting various sources while having impression of a lacking the needed information. The objective of this study is to assess the quality of the available information around MR by DIEP on Youtube.

METHODS

For this descriptive study, we reviewed 531 videos resulted from the terms "DIEP breast reconstruction". 39 videos were analyzed in detail. The evaluation criteria established from the SOFCPRE sheet were listed in 43 items divided into 4 themes. A score representing the percentage of correct information is then calculated.

RESULTS

The average length of the videos is 40'05″±46'45″. The average total score is 42.52%. Concerning the subgroups, the themes generalities and physiopathology have the highest result (66.10% of the correct items). This is followed by technique and perioperative preparation (51.65%), postoperative (27.35%) and finally complications (22.76%). Only 2 videos have an excellent total score (>80%).

CONCLUSION

The information on breast reconstruction by DIEP flap on Youtube seems insufficient and lacks quality. The surgeon should strive to provide the highest quality of information and refer patients to reliable sources.

[Satisfaction and quality of life after DIEP-flap breast reconstruction]

Satisfaction and quality of life of patients who have undergone DIEP-flap breast reconstruction have been assessed by many authors in many countries using standardized tools. However, some simple and practical information is often not found in these studies. The aim of our work was to carry out a practical satisfaction survey of patients reconstructed by DIEP flap in our center. Our cohort was made up of 207 patients who underwent DIEP-flap breast reconstruction in Marseille between January 2014 and December 2020. A letter containing our original satisfaction survey was sent to all the patients in our sample. We received 104 responses, which were statistically analyzed using the flat sorting method. Nine-two percent of patients were globally satisfied with the result of their breast reconstruction. A large majority of patients are in favor of the idea of performing their reconstruction again using a DIEP flap. Fifty-five percent of participants were "not bothered at all" by their abdomen after their surgery. The DIEP flap is a versatile technique that allows surgeons to offer it in multiple breast reconstruction situations and to obtain a high degree of patient satisfaction.

[Classification of mammary asymmetries and principles of treatment]

Constitutional breast asymmetries are responsible not only for esthetic unsightliness, but also, at times, for psychological disorders, and medical management is necessitated. While surgical treatment is the only viable therapeutic option, given the wide variety of morphological presentations of mammary asymmetries, the surgeon is called upon to be well versed in breast surgery techniques. The authors have put forward a classification of mammary asymmetries and principles of treatment.

Biological behavior of familial papillary thyroid microcarcinoma: Spanish multicenter study

PURPOSE

Familial papillary thyroid microcarcinoma (FPTMC) can present a more aggressive behavior than the sporadic microcarcinoma. However, few studies have analyzed this situation. The objective is to analyze the recurrence rate of FPTMC and the prognostic factors which determine that recurrence in Spain.

METHODS

Spanish multicenter longitudinal analytical observational study was conducted. Patients with FPTMC received treatment with curative intent and presented cure criteria 6 months after treatment. Recurrence rate and disease-free survival (DFS) were analyzed. Two groups were analyzed: group A (no tumor recurrence) vs. group B (tumor recurrence).

RESULTS

Ninety-four patients were analyzed. During a mean follow-up of 73.3 ± 59.3 months, 13 recurrences of FPTMC (13.83%) were detected and mean DFS was 207.9 ± 11.5 months. There were multifocality in 56%, bilateral thyroid involvement in 30%, and vascular invasion in 7.5%; that is to say, they are tumors with histological factors of poor prognosis in a high percentage of cases. The main risk factors for recurrence obtained in the multivariate analysis were the tumor size (OR: 2.574, 95% CI 1.210-5.473; p = 0.014) and the assessment of the risk of recurrence of the American Thyroid Association (ATA), both intermediate risk versus low risk (OR: 125, 95% CI 10.638-1000; p < 0.001) and high risk versus low risk (OR: 45.454, 95% CI 5.405-333.333; p < 0.001).

CONCLUSION

FPTMC has a recurrence rate higher than sporadic cases. Poor prognosis is mainly associated with the tumor size and the risk of recurrence of the ATA.

Assessing the effect of PRP addition to facial micro-lipofilling for patients suffering from Scleroderma: A prospective routine care analysis

BACKGROUND

Combining fat graft with platelet derived products is now common practice in regenerative surgery. We proposed to assess the safety and efficacy of Platelet-Rich Plasma (PRP) addition to a micro-lipofilling protocol for facial treatment of patients suffering from Systemic Sclerosis (SSc).

OBJECTIVE

Main objective was to evaluate the improvement of the Mouth Handicap In Systemic Sclerosis (MHISS) scale score at 6 months post-therapy.

METHOD

Included SSc patients had a MHISS score equal or up to 20. Surgery was performed under general anesthesia. Micro-fat and PRP (CCA-NA from DEPA Classification) were mixed in a 70/30 ratio, before injection in peri-oral sites according to a specific protocol. Efficacy criteria were recorded at baseline, 3 and 6 months. Moreover, we compared this cohort (current study) to a former (2015) non-enriched micro-lipofilling cohort in the same indication, using the same protocol.

RESULTS

Thirteen women patients with mean age of 53.2 years (±14.3) have been included. At baseline, mean MHISS score was 29.5 (±8.7) and significantly decreased to 22.5 (±7.8) at 6 months (P=0.016), corresponding to a 22.0% of improvement from baseline, with a mean decrease of 6.5 points (±7.5) at 6 months. Patients received a mean volume of 30.8ml PRP-micro-fat (±8.1ml).

CONCLUSION

PRP addition appeared beneficial, however, controlled studies are required to determine its superiority to facial micro-lipofilling.

X-Ray cardiac angiographic vessel segmentation based on pixel classification using machine learning and region growing

This work proposes a pixel-classification approach for vessel segmentation in x-ray angiograms. The proposal uses textural features such as anisotropic diffusion, features based on the Hessian matrix, mathematical morphology and statistics. These features are extracted from the neighborhood of each pixel. The approach also uses the ELEMENT methodology, which consists of creating a pixel-classification controlled by region-growing where the result of the classification affects further classifications of pixels. The Random Forests classifier is used to predict whether the pixel belongs to the vessel structure. The approach achieved the best accuracy in the literature (95.48%) outperforming unsupervised state-of-the-art approaches.

The two-stage free flap strategy: An alternative to reconstruct major oncological surgical defects with noble organ exposure

BACKGROUND

To minimize the risk of viscera exposure for parietal or calverial reconstruction after tumor removal, we used the two-stage free flap strategy. The flap was transferred a few days before tumor resection and left in a standby position until the second stage.

PATIENTS AND METHOD

We conducted a retrospective monocentric study. All patients who underwent reconstruction with the two-stage free flap strategy after tumor resection since 2000 were included.

RESULTS

We performed 14 two-stage flaps (8 for calvaria, 3 for abdomen, and 3 for thorax) on 12 patients. The average skin paddle surface was 318 cm². The mean operative time was 274min for the first stage and 172min for the second stage. The average time between the two stages was 8.8 days (2 to 24 days). One flap necrosis, one venous thrombosis, and one hematoma were observed after the first stage. Partial skin paddle necrosis (2 flaps) and infections (3 flaps) occurred after the second stage. The mean follow-up was 20 months (6 to 61 months), and two patients had tumor recurrence.

CONCLUSIONS

The two-stage free flap strategy is another option for major oncological reconstructions, to be safe and reliable some rules must be followed. The flap must contain a large skin paddle to ensure flap autonomization and to allow for complete tight plication of the flap between the two stages, which limits germ colonization. A short delay between the two stages (<12 days) decreases the risk of infection. The presence of a plastic surgeon during the second stage decreases the risk of pedicle trauma.

[Brachioplasty and its complications]

Due to an increasing number of major weight loss after bariatic surgery, the demand for body-coutouring surgery increase in paralell. Among all the technics which can be realized, brachioplastyis one of them. The goal is to reach a functionnal but an aesthetic improvement too. The literature show that the rate of major complication is very low (or not reported in the majority of the series). Minor complication is more common : hypertrophic scar, large scar, paresthesia, and wound dehiscence. Re-operation can be asked by the patient in order to improve the result. With the help of clinical cases and literature review the authors try to analyse the balance between benefice and risk to realize a second operation.

[Surgical treatment of recurrent pressure ulcers in spinal cord injured patients]

Not to burn one's bridges. This is the basic principle that comes immediately to the mind of the plastic surgeon when one brings up the secondary surgery of pressure ulcers, which is a common pathology in the spinal cord injured patients. Which ones are good candidates for surgical treatment? When? What preoperative, infectious, rehabilitative management is most likely to minimize the number of failures and recurrences? Which operative technique to prefer in first intention? And in case of secondary surgery, how to choose the best strategy? We will see that some cases can be treated by primarily closing or flap remobilization but, in case of greater loss of substance the realization of a flap from another anatomical region will be essential.

From cyclic nanorings to single-walled carbon nanotubes: disclosing the evolution of their electronic structure with the help of theoretical methods

We systematically investigate the relationships between structural and electronic effects of finite size zigzag or armchair carbon nanotubes of various diameters and lengths, starting from a molecular template of varying shape and diameter, i.e. cyclic oligoacene or oligophenacene molecules, and disclosing how adding layers and/or end-caps (i.e. hemifullerenes) can modify their (poly)radicaloid nature. We mostly used tight-binding and finite-temperature density-based methods, the former providing a simple but intuitive picture about their electronic structure, and the latter dealing effectively with strong correlation effects by relying on a fractional occupation number weighted electron density (ρFOD), with additional RAS-SF calculations backing up the latter results. We also explore how minor structural modifications of nanotube end-caps might influence the results, showing that topology, together with the chemical nature of the systems, is pivotal for the understanding of the electronic properties of these and other related systems.

[To harvest a SIEA flap instead of a DIEP flap in breast reconstruction: A technical note]

Breast reconstruction by abdominal flap has evolved to ensure minimal donor-site morbidity with the description of Deep Inferior Epigastric artery Perforator flap (DIEP flap). Being of the same thickness and the same surface, the Superficial Inferior Epigastric Artery flap (SIEA flap) does not require, for it harvesting, to open the abdominal fascia or to dissect through the muscles minimizing again donor-site sequelae. However, it is little used because of the variability of its vascularization and a higher failure rate than the DIEP in the literature. We believe that it is reasonable, in some cases, to harvest a SIEA flap instead of DIEP flap in mammary reconstruction. We present a technical note explaining our operative strategy for reliably taking a SIEA when the caliber of the vessels allows.

Potential Use of Squarates and Croconates as Singlet Fission Sensitizers

The geometrical and electronic structures of 44 squarate and croconate derivatives are computationally studied by quantum chemistry methods, in the pursuit of new singlet fission sensitizers. A non-negligible singlet open-shell diradical character is observed for most of the studied molecules, which can be controlled through chemical substitution as well as by the size of the central ring. Such a diradical character is related to small singlet-triplet energy gaps, facilitating the accomplishment of the singlet fission energetic requirements. In general, the present results indicate that squarates hold superior singlet fission capabilities than croconates, although we have identified several derivatives within both families as promising singlet fission sensitizers.

Lithium as a disease-modifying agent for prion diseases

Prion diseases still remain incurable despite multiple efforts to develop a treatment. Therefore, it is important to find strategies to at least reduce the symptoms. Lithium has been considered as a neuroprotective agent for years, and the objective of this preclinical study was to evaluate the efficacy of lithium delivered as a water-in-oil microemulsion (Aonys^®). This delivery system allows using low doses of lithium and to avoid the toxicity observed in chronic treatments. C57BL/6J mice were intracranially inoculated with ME7 prion-infected brain homogenates and then were treated with lithium from day 90 post inoculation until their death. Lithium was administered at traditional doses (16 mg/kg/day) by the gavage route and at lower doses (40 or 160 µg/kg/day; Aonys^®) by the rectal mucosa route. Low doses of lithium (Aonys^®) improved the survival of prion-inoculated mice, and also decreased vacuolization, astrogliosis, and neuronal loss compared with controls (vehicle alone). The extent of the protective effects in mice treated with low-dose lithium was comparable or even higher than what was observed in mice that received lithium at the traditional dose. These results indicate that lithium administered using this innovative delivery system could represent a potential therapeutic approach not only for prion diseases but also for other neurodegenerative diseases.

The role of topology in organic molecules: origin and comparison of the radical character in linear and cyclic oligoacenes and related oligomers

We discuss the nature of electron-correlation effects in carbon nanorings and nanobelts by a combined approach based on FT-DFT and RAS-SF methods.

[Treatment of wrinkles of the upper lip by emulsified fat or "Nanofat": Biological and clinical study about 4 cases]

OBJECTIVE

Emulsified fat injection showed its interest in aesthetic facial surgery. The adipose tissue harvested is mechanically emulsified and filtered. The suspension obtained is injected into the dermis through small diameter needles (27 to 30 gauges). The objective of our study was to evaluate the biological composition of emulsified fat and its clinical effectiveness in the treatment of peri-oral wrinkles in 4 patients aged 50 to 59 years.

MATERIAL AND METHOD

Each patient received an intradermal injection of emulsified fat in the peri-oral wrinkles prepared from abdominal fat under local anesthesia. The cell viability, stromal vascular fraction (FVS) composition in emulsified fat and the adipocyte differentiation capacity of mesenchymal stem cells (MSC) were studied. The clinical results were evaluated by standardized photographs, 3D microphotography, confocal microscopy, and self-evaluation of patient satisfaction over a period of 4 months.

RESULTS

The biological study of the emulsified fat found a lysis of all the adipocytes. The mean number of FVS cells was 126,330±2758 cells by cc of emulsified fat with preserved cell viability (85.1±6.84 %) and a good proportion of regeneratives cells (18.77±6.2 %). The clinical study found a tendency to decrease the volume of wrinkles on standardized photography and 3D microphotography no significative. Patients were satisfied with treatment with an average score of 7±1.15/10 to 4 months.

CONCLUSION

Intradermal injection of emulsified fat seems to be an interesting treatment of face wrinkles. Our study has shown its safety, but additional studies seems necessary to confirm its clinical efficacy.

A 1-Year Follow-Up of Post-operative Scars After the Use of a 1210-nm Laser-Assisted Skin Healing (LASH) Technology: A Randomized Controlled Trial

BACKGROUND

Laser therapies are used prophylactically for excessive scar formation. The Laser-Assisted Skin Healing treatment induces a controlled heat stress that promotes tissue regeneration. This comparative trial is the first to evaluate the performance of a new automated 1210-nm laser system, compatible with all Fitzpatrick scale phototypes.

METHODS

Forty women undergoing bilateral breast reduction were enrolled in this double-blinded randomized controlled trial. The horizontal sutured incision of one breast was treated with the portable 1210-nm laser while in the operating theatre. The other breast was used as the study control. Objective measurements, subjective clinical assessments and safety evaluation were carried out over 1 year by both clinicians and patients.

RESULTS

Six weeks following surgery, better overall appearance and modified OSAS scores were reported for the laser-treated scars when compared to the control group (p = 0.024 and p = 0.079). This supports an early effect of the laser treatment during the inflammatory stage of the healing process. After a post-treatment period of 6 months, there continued to be a strong tendency in favour of the laser treatment based on the subjective scores and corroborated by the objective improvement of the treated scar volume (p = 0.038). At 1 year, the laser-treated scars continued to improve compared to the control ones in terms of volume (p = 0.004), surface (p = 0.017) and roughness (p = 0.002), and these comparatively better results were strengthened with the blind expression of patients' preference for their laser-treated scar (p = 0.025).

CONCLUSIONS

This new 1210-nm laser treatment, used as a single session performed immediately after surgery, provides significant objective and subjective improvements in scar appearance. These data can be useful when preparing patients to undergo their surgical procedure.

[Female-to-male transgender chest reconstruction: A retrospective study of patient satisfaction]

BACKGROUND

Mammaplasty in gender reassignment surgery is often poorly understood, due to a lack of information about this condition and its therapy. The aim of this work was to evaluate patient satisfaction following bilateral mastectomy for female-to-male gender reassignment.

METHODS

We contacted 22 patients who underwent mammaplasty for female-to-male gender reassignment between January 2012 and March 2013 in our university hospital. Patients were sent postal questionnaires. A modified Q-breast questionnaire adapted for gender reassignment surgery enabled us to objectively evaluate patient aesthetic and psychological satisfaction. An overall score superior to 320 was considered as very satisfied for the patient.

RESULTS

A total of 73% of the patients answered the questionnaire. The mean score was 332/378. This score corresponded to "very satisfied" on our questionnaire. The psychological score was 54.5/60.

CONCLUSION

This study showed that a real benefit was obtained in terms of patient quality of life and self-confidence. The high level of patient satisfaction confirmed that gender reassignment mastectomy is a useful and valid procedure, which enables these patients to reclaim their place in society. It can only be considered if it is within the framework of structures that ensure comprehensive and pluridisciplinary treatment for the patient.

A thoracic parasternal granular cell tumor in a child: About one case and review of the literature, discussion about treatment guidelines, is complete resection compulsory?

Granular cell tumor is a well known soft tissue tumor, very rare in children; we describe here the first case of GCT in this particular location in a child. The diagnostic is easily done with histopathology. The treatment is based on the complete resection, no other validated treatment exists. We reviewed the literature to find out if it would be safe to consider a simple follow-up after partial resection of the tumor.

[The complications of skin expansion in paediatrics: Diagnostic, taking over and prevention]

Skin expansion is a difficult and long process in which can occur more or less serious complications. Overall complications rates describe in the literature vary between 13 and 37%. We can categorize them in major complications, which can lead to a failure maybe even an aggravation of the anterior status, and in minor complications that do not compromise the expansion process but can alter it. The main major complications are infection, skin suffering and necrosis which can lead to prosthesis exposition, leaks and technical problems with equipment dysfunctions that may cause difficulties or a failure of the inflations. The main minor complications are hematomas, seromas, valve or tube exposition, pains with paraesthesias caused by neighbouring organs compression, pathologic and unsightly scares and can lead to an important psychological impact. These complications can be due to a precarious skin's state, a material dysfunction or unpredictable technical problems but also by an inappropriate preoperative indication or planning. The emerging of a complication, however, is not synonymous to a failure of the procedure; a satisfactory reconstruction may still be obtained in 75% of all cases. The purpose of this article is to help to identify the situations at risk of complications in order to prevent, detect and treat them early.

[Autologous fat grafting in children]

Lipofilling or fat grafting transfer is defined as a technique of filling soft tissue by autologous fat grafting. The basic principle of lipofilling is based on a harvest of adipose tissue, followed by a reinjection after treatment. Lipofilling main objective is a volume defect filling, but also improving cutaneous trophicity. Lipofilling specificities among children is mainly based on these indications. Complications of autologous fat grafting among children are the same as those in adults: we distinguish short-term complications (intraoperative and perioperative) and the medium and long-term complications. The harvesting of fat tissue is the main limiting factor of the technique, due to low percentage of body fat of children. Indications of lipofilling among children may be specific or similar to those in adults. There are two types of indications: cosmetic, in which the aim of lipofilling is correcting a defect density, acquired (iatrogenic, post-traumatic scar) or malformation (otomandibular dysplasia, craniosynostosis, Parry Romberg syndrom, Poland syndrom, pectus excavatum…). The aim of functional indications is correcting a velar insufficiency or lagophthalmos. In the paediatric sector, lipofilling has become an alternative to the conventional techniques, by its reliability, safety, reproducibility, and good results.

[Forearm osteomusculocutaneous free filet flap for arm reconstruction after amputation as an alternative to shoulder disarticulation]

We report the case of a 55-year-old woman suffering from a type I neurofibromatosis (also known as Von Recklinghausen neurofibromatosis) who was diagnosed with a high-grade schwannosarcoma of the median nerve, between the upper third and the medium third of the arm, upon contact with the humerus, invading the humeral vessels. The oncologic treatment of this tumour consisted in the amputation of the arm through the surgical neck of the humerus. In order to create a laterothoracic claw, to bring a partial function of the upper limb back, we decided to realize a free fillet forearm flap. This composite flap was composed of the radius and the ulna, all the forearm muscles and the skin of the anterior side of the forearm. A humeroradial plate osteosynthesis was done and the flap was then harvested with the radial pedicle, and anastomosed to the axillar artery. This procedure gave our patient a functional stump, giving back the arm functionality, especially the claw movement.

[Technical note: iliac crest bone graft harvesting in children]

Harvesting iliac crest bone in children is special because of the presence of a thick cartilage. Constant pressure on the internal iliac fossa, ascends the skin, and moves the abdominal muscles away from the iliac crest. A single incision is then used for cutaneous and subcutaneous dissection. An internal piece of cartilage is then removed and the iliac muscle retracted in order to harvest cortical and spongy bone from the internal side of the iliac crest. That pièce of cartilage is then sutured at its initial place. During the harvesting, the surgeon needs to be careful to preserve the lateral femoral cutaneous nerve.

[Resurfacing of an ischial and trochanteric recurrent pressure sore by a pedicled fasciocutaneous anterolateral thigh flap]

Ischial pressure sores, common in paraplegic patient, are the most difficult to treat, and poor prognosis associated with a high rate of postoperative recurrence. Many surgical techniques by muscular or myocutaneous flap coverage have been described. We report an original use of a fasciocutaneous pedicled anterolateral thigh (ALTp) flap for coverage of an ischial pressure sore combined with a trochanteric pressure sore, exceeded beyond any conventional therapeutic solution. A 45-year-old paraplegic patient suffered from a trochanteric and ischial pressure sore, which had already received coverage by a muscular flap of biceps femoris and gluteus maximus. At 1 year, the result is satisfactory, with good coverage without recurrence. The fasciocutaneous ALTp flap can be a solution to cover recurrent ischial pressure sores beyond conventional methods.

Inadvertent subcutaneous injection of hypertonic saline solution during lipofilling

Subcutaneous infiltration with a mixture of plain saline and adrenaline is a useful option in lipoharvesting for autologous fat grafting. This report presents the case of 34-year-old woman who experienced inadvertent subcutaneous injection of hypertonic saline solution during body fat harvesting.

[Two cases of lymphoma in an implant capsule: A difficult diagnosis, an unknown pathology]

The anaplastic large cell lymphoma (ALCL) is a rare disease, its incidence in the United States is one case per 500,000 women and three for 100 million patients for breast single location. Forty-six cases have been reported in the literature. They can grow on any type of implant: expander prosthesis silicone and saline, smooth or textured envelope. Currently, the consensus process includes capsulectomy, removal of the implant, chemotherapy and radiotherapy. However, some authors classify under indolent disease, but we believe that some cases may escape any therapeutic and become very aggressive forms. It is therefore important to make an early diagnosis and start treatment urgently. Severity and suspicion of iatrogenic nature of ALCL have an obligation to inform future with implants.

[Current place of curettage in the management of giant congenital nevi: report of 29 patients]

SUBJECT

The management of giant nevi remains discussed to date. Curettage, early superficial technique, allows a lightening of the lesions. We wanted to define the current interest in its use, from results obtained after 20 years of experience.

PATIENTS AND METHODS

Twenty-nine patients were treated by curettage between 1991 and 2011. Surgery consisting of excision of the superficial dermis was performed between the 1st and 7th week of life in an average of 1.8 procedures. The cosmetic result was judged subjectively.

RESULTS

Healing was achieved in 7 days. We noted a few local complications but no general complications. The aesthetic results, with initial variable lightening, induced an overall parental satisfaction in 100 % of cases. A secondary heterogeneous and varying pigmentation was observed in all cases.

CONCLUSION

To date, we believe that curettage is indicated for the treatment of giant nevi in some localization difficult to treat by conventional techniques (eyebrow, those associated with many satellite nevi) or those with a psychological impact too important to support a therapeutic delay.

[Hypogastric abdominal wall reconstruction with a pedicled anterolateral thigh flap]

Looking at a full-thickness abdominal wall defect, it is necessary to use reconstructive surgery techniques. The authors present an original case of reconstruction of the abdominal wall, using an anterolateral thigh flap (ALT) harvested with vascularised fascia lata. We describe the advantages of this technique, which has rarely been used for this indication. An 80-year-old woman presenting a full-thickness abdominal wall defect of 15×18cm was reconstructed by a pedicled ALT flap. Skin wound healing was obtained within 15 days, with no complication. There was no donor site sequela. The pedicled ALT flap appears to be a good solution for hypogastric abdominal wall defect in a one step procedure. Vacularised fascia lata bring with the cutaneous flap is useful to reconstruct the abdominal fascia.

[Dorsi elastofibroma. About 14 cases, and review of the literature]

Elastofibroma dorsi is a benign tumor which usually occurs at the inferior angle of the scapula. We retrospectively reviewed 14 cases of elastofibroma dorsi, in nine patients. The patients were hospitalized in the departments of plastic surgery, orthopedic surgery or visceral surgery. Mean age was 67 years. The location of the lesions (bilateral in five patients) was typical, in the thoracoscapular region. Nine lesions were removed surgically, six shoulders were asymptomatic after surgery. Elastofibroma is a rare, slow-growing lesion. It occurs in connective tissue of the infrascapular region of elderly patients. The pathogenesis of the lesion still remains unclear. MRI and computed tomography are useful for assessment of elastofibroma dorsi, and can potentially help avoid the need for unnecessary biopsy and surgery, especially in the asymptomatic patient. It should be surgically removed only in symptomatic patients.

The V-Y latissimus dorsi musculocutaneous flap in the reconstruction of large posterior chest wall defects

Posterior chest wall defects are frequently encountered after excision of tumors as a result of trauma or in the setting of wound dehiscence after spine surgery. Various pedicled fasciocutaneous and musculocutaneous flaps have been described for the coverage of these wounds. The advent of perforator flaps has allowed the preservation of muscle function but their bulk is limited. Musculocutaneous flaps remain widely employed. The trapezius and the latissimus dorsi (LD) flaps have been used extensively for upper and middle posterior chest wounds, respectively. Their bulk allows for obliteration of the dead space in deep wounds. The average width of the LD skin paddle is limited to 10-12 cm if closure of the donor site is expected without skin grafting. In 2001 a modification of the skin paddle design was introduced in order to allow large flaps to be raised without requiring grafts or flaps for donor site closure. This V-Y pattern allows coverage of large anterior chest defects after mastectomy. We have modified this flap to allow its use for posterior chest wall defects. We describe the flap design, its indications, and its limitations with three clinical cases.

Influence network effectiveness in promoting couples' HIV voluntary counseling and testing in Kigali, Rwanda

OBJECTIVE

To identify predictors of promotion of couples' HIV voluntary counseling and testing (CVCT) in Kigali, Rwanda.

DESIGN

Analysis of CVCT promotional agent [influential network leaders (INLs), influential network agents (INAs)], and couple/invitation-level predictors of CVCT uptake.

METHODS

Number of invitations and couples tested were evaluated by INL, INA, and couple/contextual factors. Multivariable logistic regression accounting for two-level clustering analyzed factors predictive of couples' testing.

RESULTS

Twenty-six INLs recruited and mentored 118 INAs who delivered 24 991 invitations. 4513 couples sought CVCT services after invitation. INAs distributed an average of 212 invitations resulting in an average of 38 couples tested/agent. Characteristics predictive of CVCT in multivariate analyses included the invitee and INA being socially acquainted [adjusted odds ratio (aOR) = 1.4; 95% confidence interval (CI) 1.2-1.6]; invitations delivered after public endorsement (aOR = 1.3; 95% CI 1.1-1.5); and presence of a mobile testing unit (aOR = 1.4; 95% CI 1.0-2.0). In stratified analyses, predictors significant among cohabiting couples included invitation delivery to the couple (aOR = 1.2; 95% CI 1.0-1.4) and in the home (aOR = 1.3; 95% CI 1.1-1.4), whereas among noncohabiting couples, predictors included invitations given by unemployed INAs (aOR = 1.7; 95% CI 1.1-2.7). Cohabiting couples with older men were more likely to test, whereas younger age was associated with testing among men in noncohabiting unions.

CONCLUSIONS

Invitations distributed by influential people were successful in prompting couples to seek joint HIV testing, particularly if the invitation was given in the home to someone known to the INA and accompanied by a public endorsement of CVCT. Mobile units also increased the number of couples tested. Country-specific strategies to promote CVCT programs are needed to reduce HIV transmission among those at highest risk for HIV in sub-Saharan Africa.
